This layer creates a convolution kernel that is convolved
with the layer input over a single spatial (or temporal) dimension
to produce a tensor of outputs.
If use_bias
is True, a bias vector is created and added to the outputs.
Finally, if activation
is not None
,
it is applied to the outputs as well.
When using this layer as the first layer in a model,
provide an input_shape
argument
(tuple of integers or None
, e.g.
(10, 128)
for sequences of 10 vectors of 128-dimensional vectors,
or (None, 128)
for variable-length sequences of 128-dimensional vectors.
Arguments
- output_dim: Positive integer, dimensionality of each graph node output space (or dimension of graph node embedding).
- graph_conv_filters: 3D Tensor, the dimensionality of the output space (i.e. the number output of filters in the convolution).
- activation: Activation function to use
(see activations).
If you don't specify anything, no activation is applied
(ie. "linear" activation:
a(x) = x
). - use_bias: Boolean, whether the layer uses a bias vector.
- kernel_initializer: Initializer for the
kernel
weights matrix (see initializers). - bias_initializer: Initializer for the bias vector (see initializers).
- kernel_regularizer: Regularizer function applied to
the
kernel
weights matrix (see regularizer). - bias_regularizer: Regularizer function applied to the bias vector (see regularizer).
- activity_regularizer: Regularizer function applied to the output of the layer (its "activation"). (see regularizer).
- kernel_constraint: Constraint function applied to the kernel matrix (see constraints).
- bias_constraint: Constraint function applied to the bias vector (see constraints).
Input shapes
- 4D tensor with shape:
(samples, timestep, num_graph_nodes, input_dim)
Output shape
- if
return_sequences
4D tensor with shape:(samples, timestep, num_graph_nodes, output_dim)
- else
4D tensor with shape:(samples, num_graph_nodes, output_dim)

Web as a platform "is a non-starter. If I write a mashup using data from three sources, I'm relying on the reliability of all three of those sources (which opens me up to a lot of risk that I have very little control over). Given that I may be competing with one or more of them (if I make their data more valuable, I'm probably taking some of their users), they don't have incentive to continue providing me with data reliably, unless they start charging me for the data"

2 The Palmer Penguins
The data in the palmerpenguins
package in R include size measurements, clutch observations, and blood isotope ratios for adult foraging Adelie, Chinstrap, and Gentoo penguins observed on islands in the Palmer Archipelago near Palmer Station, Antarctica8. The data were collected and made available by Dr. Kristen Gorman and the Palmer Station Long Term Ecological Research (LTER) Program.
For more on the palmerpenguins
package, visit https://allisonhorst.github.io/palmerpenguins/.
2.1 Package Loading, then Dealing with Missing Data
To start, let’s load up the necessary R packages to manage the data and summarize it in a small table, and a plot. We’ve actually done this previously, but we’ll repeat the steps here, because it’s worth seeing what R is doing.
In this case, we’ll load up five packages.
library(palmerpenguins) # source for the data set
library(janitor) # some utilities for cleanup and simple tables
library(magrittr) # provides us with the pipe %>% for code management
library(dplyr) # part of the tidyverse: data management tools
library(ggplot2) # part of the tidyverse: tools for plotting data
It’s worth remembering that everything after the #
on each line above is just a comment for the reader, and is ignored by R. We’ll see later that the loading of a single package (called tidyverse
) gives us both the dplyr
and ggplot2
packages, as well as several other useful things.
Next, let’s take the penguins
data from the palmerpenguins
package, and identify those observations which have complete data (so, no missing values) in four variables of interest. We’ll store that result in a new data frame (think of this as a data set) called new_penguins
and then take a look at that result using the following code.
new_penguins <- penguins %>%
filter(complete.cases(flipper_length_mm, body_mass_g, species, sex))
new_penguins
# A tibble: 333 x 8
species island bill_length_mm bill_depth_mm
<fct> <fct> <dbl> <dbl>
1 Adelie Torgersen 39.1 18.7
2 Adelie Torgersen 39.5 17.4
3 Adelie Torgersen 40.3 18
4 Adelie Torgersen 36.7 19.3
5 Adelie Torgersen 39.3 20.6
6 Adelie Torgersen 38.9 17.8
7 Adelie Torgersen 39.2 19.6
8 Adelie Torgersen 41.1 17.6
9 Adelie Torgersen 38.6 21.2
10 Adelie Torgersen 34.6 21.1
# ... with 323 more rows, and 4 more variables:
# flipper_length_mm <int>, body_mass_g <int>, sex <fct>,
# year <int>
2.2 Counting Things and Making Tables
So, how many penguins are in our new_penguins
data? When we printed out the result, we got an answer, but (as with many things in R) there are many ways to get the same result.
nrow(new_penguins)
[1] 333
How do our new_penguins
data break down by sex and species?
new_penguins %>%
tabyl(sex, species) # tabyl comes from the janitor package
sex Adelie Chinstrap Gentoo
female 73 34 58
male 73 34 61
Note the strange spelling of tabyl
here. The output is reasonably clear, but could we make that table a little prettier, and while we’re at it, can we add the row and column totals to it?
new_penguins %>%
tabyl(sex, species) %>%
adorn_totals(where = c("row", "col")) %>% # add row, column totals
kable # one convenient way to make the table prettier
| sex | Adelie | Chinstrap | Gentoo | Total |
|---|---|---|---|---|
| female | 73 | 34 | 58 | 165 |
| male | 73 | 34 | 61 | 168 |
| Total | 146 | 68 | 119 | 333 |
2.3 Visualizing the Data in a Graph (or a few…)
Now, let’s look at the other two variables of interest. Let’s create a graph showing the association of body mass with flipper length across the complete set of 333 penguins.
ggplot(new_penguins, aes(x = body_mass_g, y = flipper_length_mm)) +
geom_point()
Some of you may want to include a straight-line model (fit by a classical linear regression) to this plot. One way to do that in R involves the addition of a single line of code, like this:
ggplot(new_penguins, aes(x = body_mass_g, y = flipper_length_mm)) +
geom_point() +
geom_smooth(method = "lm", formula = y ~ x,
col = "red", se = FALSE)
Whenever we build a graph for ourselves, these default choices may be sufficient. But I’d like to see a prettier version if I was going to show it to someone else. So, I might use a different color for each species, and I might neaten up the theme (to get rid of the default grey background) and add a title, like this.
ggplot(new_penguins, aes(x = body_mass_g, y = flipper_length_mm, col = species)) +
geom_point() +
theme_bw() +
labs(title = "Flipper Length and Body Mass for 333 of the Palmer Penguins")
2.4 Six Ways To “Improve” This Graph
Now, let’s build a new graph. Here, I want to:
- plot the relationship between body mass and flipper length in light of both Sex and Species
- increase the size of the points and add a little transparency so we can see if points overlap,
- add some smooth curves to summarize the relationships between the two quantities (body mass and flipper length) within each combination of species and sex,
- split the graph into two “facets” (one for each sex),
- improve the axis labels,
- improve the titles by adding a subtitle, and also adding in some code to count the penguins (rather than hard-coding in the total number.)
ggplot(new_penguins, aes(x = body_mass_g, y = flipper_length_mm,
col = species)) +
geom_point(size = 2, alpha = 0.5) +
geom_smooth(method = "loess", formula = y ~ x,
se = FALSE, size = 1.5) +
facet_grid(~ sex) +
theme_bw() +
labs(title = "Flipper Length and Body Mass, by Sex & Species",
subtitle = paste0(nrow(new_penguins), " of the Palmer Penguins"),
x = "Body Mass (g)",
y = "Flipper Length (mm)")
2.5 A Little Reflection
What can we learn from these plots and their construction? In particular,
- What do these plots suggest about the center of the distribution of each quantity (body mass and flipper length) overall, and within each combination of Sex and Species?
- What does the final plot suggest about the spread of the distribution of each of those quantities in each combination of Sex and Species?
- What do the plots suggest about the association of body mass and flipper length across the complete set of penguins?
- How does the shape and nature of this body mass - flipper length relationship change based on Sex and Species?
- Do you think it would be helpful to plot a straight-line relationship (rather than a smooth curve) within each combination of Sex and Species in the final plot? Why or why not? (Also, what would we have to do to the code to accomplish this?)
- How was the R code for the plot revised to accomplish each of the six “wants” specified above?

A Peer-to-Peer Electronic Cash System
Created by: Brian Phelps
What is Bitcoin
A purely peer-to-peer version of electronic cash that allows online payments to be sent directly from one party to another without going through a trusted third party.
Double Spending Problem
Back in the early 1990s, developers and cryptographers were trying to solve the double-spend problem.
Digital currencies are just another form of digital files.
Bitcoin is the first protocol to solve this problem.
Timestamp Server
Need a way to publically publish time stamps.
Each timestamp includes the previous timestamp in its hash, forming a chain, with each additional timestamp reinforcing the ones before it.
Proof of Work
In order to add a new block, you need to spend a lot of hash power. Therefore, connection between blocks should not be easy to make.
Connection requires a lot of hash power, electricity, and it takes time.
Network
Bitcoin network is comprised many nodes. Currently, nodes do not mine.
Incentive
Cost for you to mine a block.
If you're able to successfully mine a block, you will get a block reward.
First transaction on block goes to the miner.
Next transaction comes from other wallets.
First transactions on block are called coinbase transactions, no relation to the company coinbase or the exchange.
Reclaiming Disk Space
You do not need to store all of the hashes on the chain, you can store a hash of the hashes.
This is what is meant by a Merkle Tree described in the white paper.
Simplified Payment Verification
SPV only uses portion of network.
It is possible to verify transactions without running a full network node. A user needs only to keep a copy of block headers.

Why I Agreed To Become Tottenham’s Coach – Mourinho
by Oladipo AbiolaNewly appointed Tottenham manager, Jose Mourinho has revealed what made him agree to become the manager of the North London club.
Speaking after his appointment, Mourinho noted that the abundant talent in the first team, as well as the academy, convinced him to join the English Premier League side.
“I am excited to be joining a club with such a great heritage and such passionate supporters.
“The quality in both the squad and the academy excites me. Working with these players is what has attracted me,” he said.
Recall the Portuguese coach, who had coached Porto, Chelsea, Inter, Real Madrid and Manchester United in the past took over at Tottenham from Mauricio Pochettino who was sacked by the club on Tuesday.
Mourinho, who had been out of work since leaving Manchester United in December 2018 signed a deal which will see him take charge of Tottenham till the 2022/23 season.
Naija News reports his first game will be at the London Stadium on Saturday as Spurs travel to take on West Ham in the Premier League.


Preparation time

Cooking time
10 to 30 mins
Serves
Serves 4
A showy, high-class dish to impress your friends, combining tender beef fillet and succulent lobster.
For the lobster ravioli, blend the salmon and garlic in a food processor until smooth.
Add the egg whites to the blended salmon a little at a time, blending after each addition.
Add the double cream to the salmon and egg mixture in a thin stream, blending all the time, until all of the cream has been incorporated into the mixture. Season, to taste, with salt.
Transfer the salmon mixture to a bowl, cover, and chill in the fridge until firm, about 30 minutes.
Meanwhile, for the spring vegetables, bring a large pan of salted water to the boil, then add the carrots, leeks, turnips, peas, asparagus and mushrooms and boil for three minutes. (If you don’t have a pan large enough to hold all of the vegetables, divide them among several pans.)
Drain the vegetables, then plunge them into ice-cold water to refresh. When the vegetables are cold, drain again, then set aside until needed.
When the salmon has chilled, make the ravioli. Using a small teaspoon (or a piping bag), place a marble-sized amount of the chilled salmon mixture into the centre of one of the wonton wrappers.
Repeat the process until half of the wonton wrappers and all of the salmon mixture have been used up.
Place one slice of the cooked lobster and one watercress leaf on top of each portion of salmon mixture.
One by one, brush the edges of one side of each of the remaining wonton wrappers with a little cold water. Place it, moistened-side down, on top of the prepared ravioli, pressing down at the edges to seal the two wonton wrappers together. Trim away any excess using a sharp knife.
Repeat the process with the remaining wonton wrappers to create ravioli. Cover the ravioli with clingfilm and set aside.
For the beef, preheat the oven to 180C/350F/Gas 4.
Roll the beef fillet tightly in heatproof cling film (see tip below) to form a perfect cylindrical shape, then – with the cling film still on – slice the fillet into four equal portions. Season both sides of each fillet slice with salt.
Heat an ovenproof frying pan over a medium to high heat, then add the oil. When the oil is hot, fry the fillets for 20-30 seconds on each side, or until browned on both sides.
Transfer the pan to the oven and continue to cook the beef fillets for four minutes (for medium-rare), or until cooked to your liking.
Remove the beef fillets from the pan and remove the cling film from each. Return the pan to the heat and fry the parts of the beef that were wrapped in cling film, turning regularly, until browned all the way around.
Set the beef fillets aside to rest for 5-10 minutes. Keep warm.
Add the mushrooms and lobster claws to the pan that the beef was cooked in and fry for 1-2 minutes, or until warmed through.
Meanwhile, for the spinach, heat the butter in a frying pan over a low to medium heat. When the butter has melted, add the spinach and fry, stirring constantly, until wilted. Remove from the heat and keep warm.
Bring two large pans of salted water to the boil, then reduce the heat until the water is simmering.
Add the spring vegetables to one pan and the ravioli to the other (in batches if necessary). Simmer for 4-5 minutes, or until the vegetables are cooked to your liking and the ravioli are cooked through. Drain well.
To serve, divide the spring vegetables equally among four serving bowls. Spoon over some of the fried mushrooms. Place one fillet of beef on top of each portion. Rest one lobster claw on top of each fillet. Divide the ravioli among the four dishes, placing them on top of the beef and lobster. Drizzle over some of the hot beef jus.

Imagine that a task is given to extract textures of a cat in an image. A texture can be typically how a particular object appears in an image. So we need a texture descriptor model to analyze various textures. Most of the models out there work on greyscale images rather than on colour images. This is because if we convert an image into greyscale, then we will have an NxN matrix containing the values of pixel intensities of that image. Then we can analyze the distribution of these features within the image. One of the texture descriptors is GLCM ( Gray-Level Co-occurrence Matrix). And GLCM gives a global representation of the texture. Unlike GLCM Local binary pattern computes a local representation of the texture, by comparing each pixel with its neighbouring pixels.
For example consider a 3x3 matrix out of a grayscale image pixel matrix. Click on Play...

Mark 14:68
But he denied, saying, I know not, neither understand I what thou sayest.


Approximately 10 months ago, I was prescribed Effexor XR for a sudden anxiety problem that developed seemingly overnight. I was 21 at the time.
As the months went on, my doctors continued to increase my dose from 37.5 mg to 225 mg/day.
My main reason for adding this report is to describe how coming off Effexor has affected my life.
After about 5 months I started to experience severe jaw pain on the left side, which over the next few weeks moved to the right side as well. I also had night terrors nearly every night for weeks, to the point where I was afraid to sleep.
At this point, and after reading several similar reports online describing similar symptoms relating to Effexor, I decided to slowly wean myself off of it. My stomach had been upset the entire time I was on Effexor (very very badly), but even more so when I was coming off it. My doctor had warned me that if I wasn't careful coming off of it, I could end up on IV's in the hospital, unable to eat etc. She was taking Effexor as well, so I trusted her.
Eventually it took me a total of probably a month and a half to get to get down to 37.5 and from there I opened up the capsules and lessened the amount each day until I was completely off it. (this was suggested by my doctor as well)
Now the fun part.
Ever since I came off Effexor I've experienced 'brain shivers' 'zaps' whatever you want to call them, constantly (about 15 times a minute, literally). The feeling is similar to an electric shock that originates in the brain and quickly spreads to the outer limbs, many times it comes in threes and fours. It also seems to make a zapping noise, or the feeling of hitting my funny bone, but in my brain. I also lost about 15 pounds.
This has continued, unrelentingly, for more than a month now.
I used consider myself a relatively well adjusted person. I had great grades, and I attend a very reputable university. But I have never felt so disconnected from life. Nothing that used to amuse me does anymore and I have absolutely no desire to finish school.
I cry at the drop of a hat, mostly when I'm by myself. And it takes only the slightest inconvenience to completely set me off in anger.
I know exactly why it's happening, but it feels like there is nothing I can do to overcome the feelings that Effexor has left me with.
I'd also like to note an experience that happened to me when I was taking Effexor.
I had some visitors for the weekend, and we decided to go out to the bars and have night on the town. Around 10 pm, despite having company, I felt so sick that I had to leave the bar and go back to my apartment. I had about half of my first drink before I left.
From about 11pm until about 7am I vomited uncontrollably, and I couldn't understand why, because I hadn't been drinking.
At about 7:30, I clued into the fact that with all of the hustle and bustle of company arriving in the morning, I'd forgotten to take my Effexor.
I took a gravol to try to alleviate the nausea but quickly threw it up.
Eventually I was able to get my Effexor pills down, and lie in bed until everything subsided. This chemical is grossly misunderstood and understudied.

Atmospheric Model on your iOS device
Kudos to Al Hedin, who for several decades now has been the leader of a project to make the most comprehensive model of the atmosphere from the surface to the the exosphere (e.g. 500 km altitude). I never thought pouring over the MSIS FORTRAN code as a grad student that someday I would have (not only!) a phone in my pocket but one that could run that model, which needed a DEC VAX to compile (yup, pre-PC/Mac).
My new favourite iPhone app! This free app will be a useful professional, student and outreach tool.


LSD being all but extinct in Central Florida, I decided to dose on its red-headed step child, LSA. After all, how much of a difference can one letter make.
4:00pm - I dumped out all of my seeds into a huge pile, and began counting out my dose.  I lit a celabration cigarette, and started eating.
4:30pm - I finished choking down the store-bought seeds, funguscides and all. Smoked an accomplishment cigarette.
5:00pm - It's been about four cigarettes since I swallowed my last seed, and I'm starting to feel somthing. Mainly horrible nausea, and a pain in my legs.
5:15pm - My cell phone rings. I miss the call, because for some reason I can't tell where the ringing was coming from. My complete lack of sound perception was the first sign of the trip to come.
I pop in a favorite movie of mine, 'GO'.
5:45pm - I got into the movie, and the next thing I knew, I noticing undeniable, acid-like visual distortions (though they were relatively mild). All of the characters in the movie had the primary colors shooting out from their sillouettes. Everything seemed really 'pixelated'.
6:10pm - I looked around my living room, and I felt like I was in a pastel painting. It was beutiful, yet simple.
Spent about ten mintues staring at my A/C vent, watching it spin into itself. Pure insanity.
6:25pm - My nausea had almost completely subsided, and I was having a pretty decent trip. I put on some tunes and explored my house. I was captivated by just about everything I walked past.
7:00pm - I layed down in my bed, and the peak of my trip was becoming surprisingly strong. I noticed a single geometric pattern spining, taking up my entire field of view. My feelings of 'Wow, a pattern' turned into 'This pattern is God, I must listen to God', and eventually to complete ego loss.
9:00pm - The pattern started fading, and I was slowly re-entering reality. There were still tracers-a-plenty, and lots of other noticable effects.
10:00pm - I'm just about baseline, with an empty pack of cigarettes.
**Comments**
Surprisingly good trip. It doesn't compare to acid in intensity, but it's the best high you'll find in Home Depot.
Though the pattern was pretty good, there was only one. The entire trip, I was staring at the same 2-d pattern.
I may have downplayed the nausea in the report, but it is really bad. I threw up at least five times. But it will eventually subside.

I ate a piece of hash cake while I was in a very good mood and eagerly waiting for my girlfriend who was visiting a friend. I expected her to come home late and because she had to leave next morning, and be away for some time, we were planning not to sleep much this night. So I thought about something to keep me awake, and remembered the bag of yohimbe bark that I bought about 3 or 4 years ago.
I put three teaspoons in a pot with two cups of water, heated it and as I watched it and smelled it I decided that I thought it better not to boil it, I don't know why but it seemed to me that it was the right way to treat this plant. I don't know if it matters but it might change the combination of active components in the brew. So I just kept it at the point before boiling when tiny bubbles come up from the bottom of the pot for 15 or 20 minutes.
I drank the tea with honey and a little old world elderberry juice that my girlfriend had made. It tasted really good.
I was feeling very good afterwards, not tired, but no speedy / heart beating effects either, a very light and pleasant high, thinking more clearly compared to the usual effects of hashish. when she came home, we spend the night talking and eating and everything was fine. we went to bed, slept for 2 hours. When we were waking up, I already had an erection that wouldn't go away. The sex we had (12 hours after drinking the yohimbe brew) was definitely prolonged and my orgasm was great. It was a bit harder to keep in touch with my girlfriend's feelings, but with a little concentration it was no problem and she enjoyed it at least as much as me.
After that and a small breakfast, I took her to the other side of the city where she was leaving, still not feeling tired, went for a walk, played a little guitar and slept very pleasantly and without problems.
I feel that it was (for me) just the right way of using this bark, and just the right dosage as well. no need to try and take more cause it did just what I wanted it to do.

Getting Started with Qt Purchasing in QML
This guide assumes that you have registered the in-app products for your application in the external store. For more information about registering products, see Registering Products in Google Play and Registering Products in App Store
Preparing The Application
Use the following import
statement in the QML files to access the Qt Purchasing QML types:
import QtPurchasing 1.0
Add the following statement to your .pro
file to link against the Qt Purchasing library:
QT += purchasing
Registering Products
Before you can operate on the products in your code, they must be registered in the QML graph. You start by making a Store item, and then create each product as a child of this.
Store { Product { identifier: "consumableProduct" type: Product.Consumable // ... } Product { identifier: "unlockableProduct" type: Product.Unlockable // ... } }
As you can see, there are consumable products and unlockable products. The former can be purchased any number of times by the same user, while the latter can only be purchased once.
The Product Declaration
For each product you must fill out the identifier
, before the product can be queried from the external store. You should also always add a onPurchaseSucceeded and a onPurchaseFailed handler if you intend to provide the option to purchase the products. If you are also using the restore functionality, you should add a onPurchaseRestored handler to your unlockable products.
The signal handlers should handle the incoming transaction. Once the transaction has been handled appropriately, it should be finalized. For instance, when a purchase has succeeded, it's appropriate to save information about the purchased product in persistent storage, so that this product can still be available the next time the application launches.
The following example calls custom methods to save data about a succeeded purchase so that it survives across application runs. After verifying that the data has been stored, it finalizes the transaction. When the transaction has failed, it displays information about the failure to the user and finalizes the transaction.
Store { id: store Product { id: healthPotionProduct identifier: "healthPotion" type: Product.Consumable property bool purchasing: false onPurchaseSucceeded: { if (!hasAlreadyStoredTransaction(transaction.orderId)) { ++healthPotions if (!addHealthPotionToPersistentStorage(transaction.orderId)) { popupErrorDialog(qsTr("Unable to write to persistent storage. Please make sure there is sufficient space and restart.")) } else { transaction.finalize() } } // Reset purchasing flag purchasing = false } onPurchaseFailed: { popupErrorDialog(qsTr("Purchase not completed.")) transaction.finalize() // Reset purchasing flag purchasing = false } } }
If a transaction is not finalized, it will be called again for the same transaction the next time the application starts up, providing another chance to store the data. The transaction for a consumable product has to be finalized before the product can be purchased again.
Purchasing A Product
In order to purchase a product, call the object's purchase() method. This launches a platform-specific, asynchronous process to purchase the product, for example by requesting the user's password and confirmation of the purchase. In most cases, you should make sure that the application UI is not accepting input while the purchasing request is being processed, as this is not handled automatically on all platforms.
The following example adds a button to be used with the example product in the previous section:
Rectangle { id: button width: 100 height: 50 Text { anchors.centerIn: parent text: qsTr("Buy health potion for only " + healthPotionProduct.price + "!") } MouseArea { enabled: !healthPotionProduct.purchasing && healthPotionProduct.status === Product.Registered anchors.fill: parent onClicked: { healthPotionProduct.purchasing = true healthPotionProduct.purchase() } } }
When the button is clicked, the purchase process is started. At some point in the future, either the onPurchaseFailed handler will be called (for example if the user cancels the transaction), or the onPurchaseSucceeded handler will be called.
Note: The button is only enabled if the product's status is set to Registered. The registration process for a product is asynchronous, so purchases attempted on a product before it has been successfully registered will always fail.
Restoring Previously Purchased Products
If the application is uninstalled and subsequently reinstalled (or installed by the same user on a different device) you should provide a way to restore the previously purchased unlockable products in the external market place.
To start the process of restoring purchases, you should call the restorePurchases() method in the Store object. This will cause the onPurchaseRestored handler to be called in each of the application's unlockable products that has previously been purchased by the current user.
Continuing on the example from before, which could be some sort of role-playing computer game, lets imagine that the game has downloadable content that you can buy to expand the game further. This should be an unlockable product, because the user should not have to purchase it more than once.
Store { id: store // ... other products Product { id: dlcForestOfFooBarProduct identifier: "dlcForestOfFooBar" type: Product.Unlockable property bool purchasing: false onPurchaseSucceeded: { if (!hasMap("forestOfFooBar.map")) { if (!downloadExtraMap("forestOfFooBar.map")) { popupErrorDialog(qsTr("Unable to download The Forest of FooBar map. Please make sure there is sufficient space and restart.")) } else { transaction.finalize() } } // Reset purchasing flag purchasing = false } onPurchaseFailed: { popupErrorDialog(qsTr("Purchase not completed.")) transaction.finalize() // Reset purchasing flag purchasing = false } onPurchaseRestored: { if (!hasMap("forestOfFooBar.map")) { if (!downloadExtraMap("forestOfFooBar.map")) { popupErrorDialog(qsTr("Unable to download The Forest of FooBar map. Please make sure there is sufficient space and restart.")) } else { transaction.finalize() } } } } }
If a user buys the downloadable content and later either installs the game on another device or uninstalls and reinstalls the game, you can provide a way to restore the purchase, such as the following button:
Rectangle { id: restoreButton width: 100 height: 50 Text { anchors.centerIn: parent text: "Restore previously purchased content" } MouseArea { anchors.fill: parent onClicked: { store.restorePurchases() } } }
Restoring purchases should always be done as a reaction to user input, as it may present a password dialog on some platforms. Calling the restorePurchases() method launches the restore process asynchronously. At some point in the future the onPurchaseRestored handler will be called if the product has previously been purchased.
Note: While the function behaves as documented on Android, this functionality is technically not needed there. The reason for this is that the Android device manages all unlockable purchases with no intervention from the application. If an application is uninstalled and reinstalled (or installed on a different device) on Android, then onPurchaseSucceeded will be called for each previously purchased, unlockable product when the application starts up.


Titanic (1997) Rated PG-13 for disaster related peril and violence, nudity, sensuality, and some language. ---------- Out of 4 stars: **** (4 Stars)
Starring: Leonardo DiCaprio, Kate Winslet, Billy Zane, Kathy Bates, Gloria Stuart, Danny Nucci, Bernard Hill, David Warner, Bill Paxton, Frances Fisher, Jonathan Hyde.
First off, I have been waiting for TITANIC to be released into theaters ever since I first heard they were making it. Hearing James Cameron would direct, I was a little worried that he would turn it into an action film. I felt that the maiden voyage of the R.M.S. Titanic had more going for it than action, and it deserved more respect (not that I'm saying the action genre isn't respectful... or maybe I am). Upon seeing the first previews of the film (over a year ago), I realized that Cameron had created something that has to be seen. It wasn't going to be an action film, but a romantic love story revolving around the Titanic's disastrous voyage. And then, come July, and I heard the worst news of the year--TITANIC was being pushed to December. I was incredibly disappointed, but the film's trailers still loomed in my mind. December 19 was approaching fast, but it seemed to take forever.
And then it hit theaters. I bought tickets the night before, just to make sure I had them. The film's title appeared in big, bold letters against an oceanic background. I let out a small cheer for myself and the film. For over three hours, I sat in my seat, spellbound. There really are no words to describe it. This is an experience one must see to believe. The trailers make it look like an action-packed, visual-effects filled story that had a romance story as a subplot. Instead, the sinking of the Titanic is the subplot, while the romance becomes the film's center. On exiting the theater (and wiping away the tears), I overheard comments from an audience member who thought it was going to be a disaster film filled with peril and death. This was a rather tasteless remark, and I wanted to turn to him and ask him if he had ever seen any of the previews. However, he was partially right... it is filled with death and peril. But only for the final hour or so.
TITANIC begins deep under the ocean (over two and half miles below the surface). The dark blue surrounds the camera's view, and then a light in the background appears. Several small submarines move in the darkness (reminiscent of Cameron's THE ABYSS) and the light shines upon a "ghost ship coming out of the darkness." What's so remarkable about this scene is that these shots are actual footage of the real Titanic. Cameron shot this footage, taking shots from inside the ship with small vessels attached to cables. The head of these excursions into the Titanic is led by Brock Lovett (Bill Paxton), an explorer hoping to find a valuable diamond which was believed to be aboard the ship. Instead of finding the diamond, they find a safe full of drawings and other rotted paper. One of these drawings is of a nude woman, who happens to be wearing the diamond, appropriately called The Heart of the Sea.
Showing the picture on the TV, Lovett receives a phone call from Rose Calvert (Gloria Stuart), who claims to be the woman in the picture. She is flown in, where she begins to tell a story about a woman, Rose DeWitt Butaker (Kate Winslet). Rose is a 17 year old girl being forced to marry a man she does not love. This man is Cal Hockley (Billy Zane), a rich eccentric with more love for his money than Rose. Calvert's story begins with these two arriving at the farewell of the R.M.S. Titanic, nicknamed "The Unsinkable." The first class members board with pets and luggage, while third class members need to be checked for lice and other diseases before boarding. A poor artist, Jack Dawson (Leonardo DiCaprio), wins a ticket for third class during a poker game. His friend, Fabrizio De Rossi (Danny Nucci), also boards in order to escape to America. Shortly after the ship leaves the dock, Jack spots Rose standing on the first class level.  Jack stops her, and the two begin a friendship which later turns into a passionate affair.
As all this is going on, the ship itself is being pushed to its limits. Considered to be the fastest and largest moveable manmade object, one passenger, Bruce Ismay (Jonathan Hyde), wants Captain E.J. Smith (Bernard Hill) to break the speed record. Against fair warnings, the Captain complies and pushes the ship to full power. This, of course, leads to the demise of the Titanic. The sinking of the Titanic is by far the most exhilarating moments I have ever seen on screen. The awesome grandeur of this sequence is perfect film making. Sure, there may be a couple moments where the special effects waver, but that is not important to the story or to Cameron. The incredible suspense that amounts is more than any other film this year, surpassing the terrific CONTACT's transportation moment. I thought I had seen everything, from the White House exploding, to the destruction of an entire city. But I had never seen anything like this. The energy this scene creates alone would power any other film. But TITANIC has much more to offer than any other film. It combines humor, romance, action, suspense, and sex into one incredible motion picture that defies explanation.
Of course, TITANIC's central aspect is the love story between Jack and Rose, and the crush it has on Cal. The romantic story isn't original, but this is not a bad thing. Cameron re-invents the story to fit the time period and its characters. Everything fits perfectly, with nothing ever seeming contrived or awkward. Jack's immediate interest in Rose, and Rose likewise, is completely understandable. She is suffering emotionally, and Jack is there to support her. Themes from Romeo and Juliet are included, such as Rose being an upper-classman, and Jack being lower class. But the emotional connection between Rose and Jack is almost palpable, and this fuels the film's first two hours. We watch the trials of Jack and Rose, and as they overcome them, the ship comes closer to destiny. With a ship as large as the Titanic was, it was destined to crash. And of course, the ship isn't stocked with enough lifeboats to accommodate the 2,200 passengers.
The resolution of the film, after the ship's gone under, is just as powerful as anything else in the movie. It ends rather surprisingly, with a touching symbolic conclusion. Most films end predictably, or inappropriately, but TITANIC ends just on the right note. In fact, the symbolism of the final scene is so perfect, that many people will contemplate over the meaning for months. The film does end rather depressingly, and unexpectedly, but when you think about it, it couldn't have ended any other way. All the questions are answered, and we are left with a weak smile due to the intense situation we were just put through. The Titanic sinking is an emotional roller coaster, with many more realistic deaths than any INDEPENDENCE DAY. The death scenes are so realistic, that you find yourself caring for every single passenger. Cameron never compromises the integrity of his film, and the deaths of the passengers is never overemphasized. He doesn't linger on each death, but takes it as it comes to show us the realism without trying to force emotions out of the audience. But emotions do show, and almost anyone will find themselves wiping away a few tears.
TITANIC's technical effects are the most impressive of any film this year. The production design, by Peter Lamont, is so meticulous in the small details, that we never realize the impact it has on the overall production. Everything, from the silverware to the enormous furnaces and engines, is perfectly in place. The cinematography, by Russell Carpenter, is incredibly rich. The detail in each shot is quite exquisite, and the visuals are very impressive without seeming too much like artificial visuals to make us gawk. What we gawk at is the realism. The pistons that spin the propellers are huge, but the visual impact is even stronger. Since TITANIC is a period piece, the costumes, by Deborah Lynn Scott, had to be perfect. And they are. Nothing seems like it doesn't belong in the early 20th century. And then, there are the special effects. Combining the power of Industrial Light & Magic with Cameron's Digital Domain (as well as a couple other companies), TITANIC contains the most impressive special effects this year, and ever. Most special effects come across as effects, and nothing more. TITANIC uses special effects to enhance the realism of the story, not the other way around. The ship is brought to the screen via visual effects, models, and a near full-scale model. Watching people fall from the ship is incredible, and the death scenes were too realistic for some people in the audience. When the ship splits in half and lands back on the water, a gasp is heard from almost everyone in the audience.
Cameron, as a storyteller, is among the best ever. His technique is perfect for these kinds of expensive motion pictures. But Cameron always makes good movies, no matter what kind of a budget he may have. Perhaps the biggest downfall of TITANIC is its enormous budget. Somewhere around $200 million, TITANIC easily surpasses WATERWORLD as the most expensive film to date. But while watching TITANIC, you can see where the money went.  You want to thank Cameron for giving us a film like this one. Cameron had major control over the production of this film, taking the directing and screenwriting into his own hands. He also co-edited and co-produced. Cameron's screenplays are typically well written, with smart dialogue, funny humor, and great action. But TITANIC contains an emotional element last seen in TERMINATOR 2: JUDGMENT DAY, and elevates it even more. This is a beautifully written screenplay, with terrific humor and very dramatic situations. Thankfully, Cameron opted to focus the story on the adventures of two fictional characters, instead of many different ones. We get to know them, and care for them. By the time the ship begins to sink, we actually care that the people on the ship live, instead of watching the mayhem swallow faceless victims up.
TITANIC's cast is among the best this year. Leonardo DiCaprio is not one of my favorite actors (he was in last year's horrible WILLIAM SHAKESPEARE'S ROMEO + JULIET), but here, he sheds the cocky image (more than likely a result of Cameron's control over his actors). DiCaprio gives his best performance to date, never seeming like an actor portraying a character. However, it is Kate Winslet's performance that steals the show. Her impressive resume of work has made her one of my favorite actresses, and this just adds to it. Winslet portrays all the confusion and love and hate that any other actress couldn't do as effectively. The scenes with her and DiCaprio are emotionally charged, and the connection between the two reminds us of what good chemistry can do for a film. Billy Zane has proven to be a reliable actor, but again, he tops himself as the villain of the film. Zane adds just enough love and warmth to the role in the beginning, but as Winslet begins falling in love with DiCaprio, he sheds that image until the final moments of the film.  Gloria Stuart gives a remarkable performance in a role that marks her return during a long dry spell (her last film was in 1986). Stuart's Rose is old, but she still has the spirit of when she was 17. Her face glows with love. Bill Paxton also does a very good job, though his character is mainly there in order to begin the story. Kathy Bates gives yet another terrific turn as the real-life Mrs. Molly Brown. This ensemble cast is quite good, but it is DiCaprio and Winslet who shine on screen.
TITANIC is rated PG-13 for disaster related peril and violence, nudity, sensuality, and brief language. The nudity is not inappropriate, as it is done tastefully. Winslet appears topless, but Cameron never exploits the nudity. If we do manage to see her topless, it is not because Cameron wanted to, but because the camera happened to be there. TITANIC is a grand epic motion picture which is sure to sweep the Oscars. This is the first film since SCHINDLER'S LIST that I have wanted to win Best Picture, and has a good chance at doing it. Let's face it, James Cameron deserves some recognition for all his hard work. In fact, this is the first film since the 1993 epic that I have wanted to sweep the Oscars (which is unfortunate because I want CONTACT to win a few too). TITANIC is by far the best film of the year. TITANIC will be remembered as an instant classic, going down in history as the most expensive film ever made, but also as one of the best films ever made.

How do I fix overlapping item elements?
If your layout has images, you probably need to use imagesLoaded.
Overlaping items are caused by items that change size after a layout. This is caused by unloaded media: images, web fonts, embedded buttons. To fix it, you need to initialize or layout
after all the items have their proper size.
What is the difference between Masonry, Isotope, and Packery?
Masonry, Isotope, and Packery are all similar in that they are layout libraries. Many of their options and methods are the same.
Masonry does cascading grid "masonry" layouts. Packery does bin-packing layouts, which allow it to be used for draggable interactions.
Isotope does sorting and filtering. Isotope uses masonry layouts, as well as other layouts.
Masonry is licensed MIT and is freely available for use and distribution. Isotope and Packery have a proprietary license, where you can purchase a license for commercial projects, or use it freely for open-source projects.
The first item breaks the grid!
You most likely need to set the columnWidth
option. Without columnWidth
set, Masonry will use the width of the first item for the size of its columns.
// jQuery
$('.grid').masonry({
columnWidth: 200
});
// vanilla JS
var msnry = new Masonry( '.grid', {
columnWidth: 200
});
Error: “cannot call methods on masonry prior to initialization; attempted to call '___'”
This error occurs when your code attempts to use a method before the Masonry instance has been initialized.
// This code will trigger the "cannot call methods" error
$grid.append( $items )
// masonry method
.masonry( 'appended', $items );
// init Masonry
$grid.masonry({
// options...
});
This can happen if you have a race condition — when one piece of logic may occur before another. This could happen with imagesLoaded, Infinite Scroll, or Ajaxing content.
// race condition with imagesLoaded
$grid.imagesLoaded( function() {
// init Masonry
$grid.masonry({
// options...
});
});
// imagesLoaded will trigger after this
$grid.append( $items )
.masonry( 'appended', $items );
To resolve this, make sure that the Masonry instance has been initialized before the method is called.
$grid.imagesLoaded( function() {
// init Masonry
$grid.masonry({
// options...
});
// Masonry has been initialized, okay to call methods
$grid.append( $items )
.masonry( 'appended', $items );
});
// another fix, init Masonry first, before imagesLoaded
$grid.masonry({
// options...
});
// okay to call methods
$grid.append( $items )
.masonry( 'appended', $items );
// just do layout on imagesLoaded
$grid.imagesLoaded( function() {
$grid.masonry('layout');
});

FOOMATIC-KITLOAD
Section: Maintenance Commands (8)Updated: 2001-05-07
Index Return to Main Contents
NAME
foomatic-kitload - installs a data kit into the foomatic database.SYNOPSIS
foomatic-kitload [ -k kit-dir] [ -d dest-dir]...DESCRIPTION
foomatic-kitload installs a foomatic data kit into the local data library. It takes a -k dirname option, where dirname is the toplevel directory of a foomatic driver "kit". A "kit" is a selection of XML source files arranged exactly as in the source/section of the master database (ie, opt/driver/printer/ subdirs).Gimp-Print's foomatic-generator produces exactly such a kit.
Foomatic-kitload is moderately paranoid about kits: the kit must contain at least one of printer, driver or opt; the kit must contain only files ending in .xml, the kit cannot be the local library itself, etc. But it does not inspect the contents of the kit files in any way.
Options
- -k dirname
- dirname is the toplevel directory of a foomatic driver "kit".
- -d destdir
-
destdir is a prefix to prepend to the install path. This will not normally
be required, but is useful if installing into a temporary `staging area'
prior to installing in the final destination.
EXIT STATUS
foomatic-kitload returns 0 on success, 255 or something else when an error occurs.AUTHOR

Audio Signal Processing: Intern Projects
An exploration of the audio space inspired by the knowledge gained and experience from my Internship with Knowles Intelligent Audio.
Split Script
Voice to command technology has become ever more present in today’s devices. To test this technology, keyword utterances are required.
In my Knowles Data Collection project I organized for 30 subjects to come into the lab and record 10 instances of 9 different keywords.
(A key word example: “Hey Siri, what’s the weather like today”.)
This audio is saved as the total file but each utterance is required to be split and saved in the proper database collection. This base split script is used to take in an audio file and find the utterances. Later naming conventions and ordering was used to determine which keyword it is and where to send it in the database.
I saw an opportunity to optimize company scripts and made my own script which had a speedup due to cancelling redundant calculations.
Audio Cutter
During my internship this became a small passion project. Often times in music I enjoy, there are annoying segments whether it be instrumental or a undesired verse that irks the music listening process.
Trimming off the beginning and ending of a song is easy on iTunes but to cut out a middle section of a song causes a lot more hardship. Instead of opening up GarageBand and hand trimming the audio, concatenating them, and then exporting the audio, this python desktop application does it for you based on timestamps.
Trim Silence
After my internship I wondered how I could apply the split script methodologies to my life. Being a person passionate about collecting music, I found that a lot of audio have different levels and that downloaded music has awkward dips and pauses from the song.
This script trims off silence automatically and chooses which “utterance” to export based on length.

Welcome to the world of fashion.
Everyone is doing the fashion in this modern India. Naturally, it is related to the dress and manners. But a way implies something deeper than fashion most of the people doing the fashion, but with the fashion, the manners also important for make stability of their modernity.
Beauty is a quality that makes us feel a sense of pleasure and appreciation.As it solely depends on how ‘WE’ see beauty, there can never be an external standard of beauty.
As time has progressed fashion accessories have become more and more prominent in the immediate fashion world ranging from the runway to street wear. Today's generation of fashionistas has adopted a new way of wearing certain items to complete an outfit.
fashion tips
Despite being something that everyone does literally every day, getting dressed (or putting together an outfit, if you want to get fancy), can feel like the trickiest, most frustrating part of the morning.  Rest assured, you're not alone in this daily conundrum. To that end, we consulted a panel of experts—top designers, style consultants, and retail pros—to demystify the act (art?) of getting dressed, once and for all.
1.Balance Proportion
Obviously, you want to show off what you're proud of—toned arms or a slim waist. It's the downplaying of less beloved parts that's tricky. One tactic? Add opposite volume, like wearing wide-leg trousers to offset a heavier upper half that's wearing something fitted. "So avoid anything too oversize or you'll look bigger."
2.Wear trends in an age-appropriate way.
Odds are, there's a grown-up version of the style du jour. Take crop tops: To avoid revealing skin, pair a shirt that hits at the navel with a high-waisted skirt—or a longer top with a crop top over it. "It gives you a similar look," promises designer Rebecca Minkoff. Bottom line: "You never want to seem like you're uncomfortable with your age and trying to look younger".
Healthy Skin
Healthy and glowing skin is everyone’s dream. Try these seven absolutely natural homemade beauty tips to get healthy skin and that lasting glow.

Core Library Configuration
Core Library Configuration
This section describes the configuration settings used by DistributedLog Core Library.
All the core library settings are managed in DistributedLogConfiguration, which is basically a properties based configuration, which extends from Apache commons CompositeConfiguration. All the DL settings are in camel case and prefixed with a meaningful component name. For example, zkSessionTimeoutSeconds means the session timeout for component zk in seconds.
The default distributedlog configuration is constructed by instantiating an instance of DistributedLogConfiguration. This distributedlog configuration will automatically load the settings that specified via SystemConfiguration.
DistributedLogConfiguration conf = new DistributedLogConfiguration();
The recommended way is to load configuration from URL that points to a configuration file (#loadConf(URL)).
String configFile = "/path/to/distributedlog/conf/file"; DistributedLogConfiguration conf = new DistributedLogConfiguration(); conf.loadConf(new File(configFile).toURI().toURL());
ZooKeeper Settings
A distributedlog namespace usually creates two zookeeper client instances: one is used for DL metadata operations, while the other one is used by bookkeeper. All the zookeeper clients are retryable clients, which they would reconnect when session is expired.
DL ZooKeeper Settings
- zkSessionTimeoutSeconds: ZooKeeper session timeout, in seconds. Default is 30 seconds.
- zkNumRetries: Number of retries of each zookeeper request could attempt on retryable exceptions. Default is 3.
- zkRetryStartBackoffMillis: The initial backoff time of first retry of each zookeeper request, in milliseconds. Default is 5000.
- zkRetryMaxBackoffMillis: The max backoff time of retries of each zookeeper request, in milliseconds. Default is 30000.
- zkcNumRetryThreads: The number of retry threads used by this zookeeper client. Default is 1.
- zkRequestRateLimit: The rate limiter is basically a guava RateLimiter. It is rate limiting the requests that sent by zookeeper client per second. If the value is non-positive, the rate limiting is disable. Default is 0.
- zkAclId: The digest id used for zookeeper ACL. If it is null, ACL is disabled. Default is null.
BK ZooKeeper Settings
- bkcZKSessionTimeoutSeconds: ZooKeeper session timeout, in seconds. Default is 30 seconds.
- bkcZKNumRetries: Number of retries of each zookeeper request could attempt on retryable exceptions. Default is 3.
- bkcZKRetryStartBackoffMillis: The initial backoff time of first retry of each zookeeper request, in milliseconds. Default is 5000.
- bkcZKRetryMaxBackoffMillis: The max backoff time of retries of each zookeeper request, in milliseconds. Default is 30000.
- bkcZKRequestRateLimit: The rate limiter is basically a guava RateLimiter. It is rate limiting the requests that sent by zookeeper client per second. If the value is non-positive, the rate limiting is disable. Default is 0.
There are a few rules to follow when optimizing the zookeeper settings:
- In general, higher session timeout is much better than lower timeout, which will make zookeeper client more resilent to any network glitches.
- A lower backoff time is better for latency, as it would trigger fast retries. But it could trigger retry storm if the backoff time is too low.
- Number of retries should be tuned based on the backoff time settings and corresponding latency SLA budget.
- BK and DL readers use zookeeper client for metadata accesses. It is recommended to have higher session timeout, higher number of retries and proper backoff time.
- DL writers also use zookeeper client for ownership tracking. It is required to act quickly on network glitches. It is recommended to have low session timeout, low backoff time and proper number of retries.
BookKeeper Settings
All the bookkeeper client configuration settings could be loaded via DistributedLogConfiguration. All of them are prefixed with bkc.. For example, bkc.zkTimeout in distributedlog configuration will be applied as zkTimeout in bookkeeper client configuration.
General Settings
- bkcNumIOThreads: The number of I/O threads used by netty in bookkeeper client. The default value is numWorkerThreads.
Timer Settings
- timerTickDuration: The tick duration in milliseconds that used for timeout timer in bookkeeper client. The default value is 100 milliseconds.
- timerNumTicks: The number of ticks that used for timeout timer in bookkeeper client. The default value is 1024.
Data Placement Settings
A log segment is backed by a bookkeeper ledger. A ledger's data is stored in an ensemble of bookies in a stripping way. Each entry will be added in a write-quorum size of bookies. The add operation will complete once it receives responses from a ack-quorum size of bookies. The stripping is done in a round-robin way in bookkeeper.
For example, we configure the ensemble-size to 5, write-quorum-size to 3, and ack-quorum-size to 2. The data will be stored in following stripping way.
| entry id | bk1 | bk2 | bk3 | bk4 | bk5 | | 0 | x | x | x | | | | 1 | | x | x | x | | | 2 | | | x | x | x | | 3 | x | | | x | x | | 4 | x | x | | | x | | 5 | x | x | x | | |
We don't recommend stripping within a log segment to increase bandwidth. We'd recommend using multiple distributedlog streams to increase bandwidth in higher level of distributedlog. so typically the ensemble size will be set to be the same value as write-quorum-size.
- bkcEnsembleSize: The ensemble size of the log segment. The default value is 3.
- bkcWriteQuorumSize: The write quorum size of the log segment. The default value is 3.
- bkcAckQuorumSize: The ack quorumm size of the log segment. The default value is 2.
DNS Resolver Settings
DistributedLog uses bookkeeper's rack-aware data placement policy on placing data across bookkeeper nodes. The rack-aware data placement uses a DNS resolver to resolve a bookie address into a network location and then use those locations to build the network topology.
There are two built-in DNS resolvers in DistributedLog:
- DNSResolverForRacks: It resolves domain name like (region)-(rack)-xxx-xxx.* to network location /(region)/(rack). If resolution failed, it returns /default-region/default-rack.
- DNSResolverForRows: It resolves domain name like (region)-(row)xx-xxx-xxx.* to network location /(region)/(row). If resolution failed, it returns /default-region/default-row.
The DNS resolver could be loaded by reflection via bkEnsemblePlacementDnsResolverClass.
(region) could be overrided in a configured dnsResolverOverrides. For example, if the host name is (regionA)-(row1)-xx-yyy, it would be resolved to /regionA/row1 without any overrides. If the specified overrides is (regionA)-(row1)-xx-yyy:regionB, the resolved network location would be /regionB/row1. Allowing overriding region provides the optimization hits to bookkeeper if two logical regions are in same or close locations.
- bkEnsemblePlacementDnsResolverClass: The DNS resolver class for bookkeeper rack-aware ensemble placement. The default value is DNSResolverForRacks.
- bkRowAwareEnsemblePlacement: A flag indicates whether DNSResolverForRows should be used. If enabled, DNSResolverForRows will be used for DNS resolution in rack-aware placement policy. Otherwise, it would use the DNS resolver configured by bkEnsemblePlacementDnsResolverClass.
- dnsResolverOverrides: The mapping used to override the region mapping derived by the DNS resolver. The value is a string of pairs of host-region mappings (host:region) separated by semicolon. By default it is empty string.
Namespace Configuration Settings
This section lists all the general settings used by DistributedLogNamespace.
Executor Settings
- numWorkerThreads: The number of worker threads used by the namespace instance. The default value is the number of available processors.
- numReadAheadWorkerThreads: The number of dedicated readahead worker treads used by the namespace instance. If it is non-positive, it would share the same executor for readahead. Otherwise, it would create a dedicated executor for readahead. The default value is 0.
- numLockStateThreads: The number of lock state threads used by the namespace instance. The default value is 1.
- schedulerShutdownTimeoutMs: The timeout value in milliseconds, for shutting down schedulers in the namespace instance. The default value is 5000ms.
- useDaemonThread: The flag whether to use daemon thread for DL executor threads. The default value is false.
Metadata Settings
The log segment metadata is serialized into a string of content with a version. The version in log segment metadata allows us evolving changes to metadata. All the versions supported by distributedlog right now are listed in the below table.
| version | description |
|---|---|
| 0 | Invalid version number. |
| 1 | Basic version number. Inprogress: start tx id, ledger id, region id Completed: start/end tx id, ledger id, region id, record count and completion time |
| 2 | Introduced LSSN (LogSegment Sequence Number) |
| 3 | Introduced Partial Truncated and Truncated status. A min active (entry_id, slot_id) pair is recorded in completed log segment metadata. |
| 4 | Introduced Enveloped Entry Stucture. None & LZ4 compression codec introduced. |
| 5 | Introduced Sequence Id. |
A general rule for log segment metadata upgrade is described as below. For example, we are upgrading from version X to version X+1.
- Upgrade the readers before upgrading writers. So the readers are able to recognize the log segments of version X+1.
- Upgrade the writers with the new binary of version X+1 only. Keep the configuration ledgerMetadataLayoutVersion unchanged - still in version X.
- Once all the writers are running in same binary of version X+1. Update writers again with ledgerMetadataLayoutVersion set to version X+1.
Available Settings
- ledgerMetadataLayoutVersion: The logsegment metadata layout version. The default value is 5. Apply for writers only.
- ledgerMetadataSkipMinVersionCheck: The flag indicates whether DL should enforce minimum log segment metadata vesion check. If it is true, DL will skip the checking and read the log segment metadata if it could recognize. Otherwise, it would fail the read if the log segment's metadata version is less than the version that DL supports. By default, it is disabled.
- firstLogsegmentSequenceNumber: The first log segment sequence number to start with for a stream. The default value is 1. The setting is only applied for writers, and only when upgrading metadata from version 1 to version 2. In this upgrade, we need to update old log segments to add ledger sequence number, once the writers start generating new log segments with new version starting from this firstLogSegmentSequenceNumber.
- maxIdSanityCheck: The flag indicates whether DL should do sanity check on transaction id. If it is enabled, DL will throw TransactionIdOutOfOrderException when it received a smaller transaction id than current maximum transaction id. By default, it is enabled.
- encodeRegionIDInVersion: The flag indicates whether DL should encode region id into log segment metadata. In a global replicated log, the log segments can be created in different regions. The region id in log segment metadata would help figuring out what region that a log segment is created. The region id in log segment metadata would help for monitoring and troubleshooting. By default, it is disabled.
Namespace Settings
- federatedNamespaceEnabled: The flag indicates whether DL should use federated namespace. By default, it is disabled.
- federatedMaxLogsPerSubnamespace: The maximum number of log stream per sub namespace in a federated namespace. By default, it is 15000
- federatedCheckExistenceWhenCacheMiss: The flag indicates whether to check the existence of a log stream in zookeeper or not, if querying the local cache of the federated namespace missed.
Writer Configuration Settings
General Settings
- createStreamIfNotExists: The flag indicates whether to create a log stream if it doesn't exist. By default, it is true.
- compressionType: The compression type used when enveloping the output buffer. The available compression types are none and lz4. By default, it is none - no compression.
- failFastOnStreamNotReady: The flag indicates whether to fail immediately if the stream is not ready rather than enqueueing the request. A log stream is considered as not-ready when it is either initializing the log stream or rolling a new log segment. If this is enabled, DL would fail the write request immediately when the stream isn't ready. Otherwise, it would enqueue the request and wait for the stream become ready. Please consider turning it on for the use cases that could retry writing to other log streams, which it would result in fast failure hence client could retry other streams immediately. By default, it is disabled.
- disableRollingOnLogSegmentError: The flag to disable rolling log segment when encountered error. By default, it is true.
Durability Settings
- isDurableWriteEnabled: The flag indicates whether durable write is enabled. By default it is true.
Transmit Settings
DL writes the log records into a transmit buffer before writing to bookkeeper. The following settings control the frequency of transmits and commits.
- writerOutputBufferSize: The output buffer size in bytes. Larger buffer size will result in higher compression ratio and it would reduce the entries sent to bookkeeper, use the disk bandwidth more efficiently and improve throughput. Set this setting to 0 will ask DL to transmit the data immediately, which it would achieve low latency.
- periodicFlushFrequencyMilliSeconds: The periodic flush frequency in milliseconds. If the setting is set to a positive value, the data in transmit buffer will be flushed in every half of the provided interval. Otherwise, the periodical flush will be disabled. For example, if this setting is set to 10 milliseconds, the data will be flushed (transmit) every 5 milliseconds.
- enableImmediateFlush: The flag to enable immediate flush a control record. It is a flag to control the period to make data visible to the readers. If this settings is true, DL would flush a control record immediately after transmitting the user data is completed. The default value is false.
- minimumDelayBetweenImmediateFlushMilliSeconds: The minimum delay between two immediate flushes, in milliseconds. This setting only takes effects when immediate flush is enabled. It is designed to tolerant the bursty of traffic when immediate flush is enabled, which prevents sending too many control records to the bookkeeper.
LogSegment Retention Settings
The following settings are related to log segment retention.
- logSegmentRetentionHours: The log segment retention period, in hours. In other words, how long should DL keep the log segment once it is truncated.
- explicitTruncationByApp: The flag indicates that truncation is managed explicitly by the application. If this is set then time based retention only clean the log segments which are marked as truncated. By default it is disabled.
LogSegment Rolling Settings
The following settings are related to log segment rolling.
- logSegmentRollingMinutes: The log segment rolling interval, in minutes. If the setting is set to a positive value, DL will roll log segments based on time. Otherwise, it will roll log segment based on size (maxLogSegmentBytes). The default value is 2 hours.
- maxLogSegmentBytes: The maximum size of a log segment, in bytes. This setting only takes effects when time based rolling is disabled. If it is enabled, DL will roll a new log segment when the current one reaches the provided threshold. The default value is 256MB.
- logSegmentRollingConcurrency: The concurrency of log segment rolling. If the value is positive, it means how many log segments can be rolled at the same time. Otherwise, it is unlimited. The default value is 1.
LogSegment Allocation Settings
A bookkeeper ledger is allocated when a DL stream is rolling into a new log segment. To reduce the latency penalty on log segment rolling, a ledger allocator could be used for pre-allocating the ledgers for DL streams. This section describes the settings related to ledger allocation.
- enableLedgerAllocatorPool: The flag indicates whether to use ledger allocator pool or not. It is disabled by default. It is recommended to enable on write proxy.
- ledgerAllocatorPoolPath: The path of the ledger allocator pool. The default value is ".allocation_pool". The allocator pool path has to be prefixed with ".". A DL namespace is allowed to have multiple allocator pool, as they will be acted independently.
- ledgerAllocatorPoolName: The name of the ledger allocator pool. Default value is null. It is set by write proxy on startup.
- ledgerAllocatorPoolCoreSize: The number of ledger allocators in the pool. The default value is 20.
Write Limit Settings
This section describes the settings related to queue-based write limiting.
- globalOutstandingWriteLimit: The maximum number of outstanding writes. If this setting is set to a positive value, the global write limiting is enabled - when the number of outstanding writes go above the threshold, the consequent requests will be rejected with OverCapacity exceptions. Otherwise, it is disabled. The default value is 0.
- perWriterOutstandingWriteLimit: The maximum number of outstanding writes per writer. It is similar as globalOutstandingWriteLimit but applied per writer instance. The default value is 0.
- outstandingWriteLimitDarkmode: The flag indicates whether the write limiting is running in darkmode or not. If it is running in dark mode, the request is not rejected when it is over limit, but just record it in the stats. By default, it is in dark mode. It is recommended to run in dark mode to understand the traffic pattern before enabling real write limiting.
Lock Settings
This section describes the settings related to distributed lock used by the writers.
- lockTimeoutSeconds: The lock timeout in seconds. The default value is 30. If it is 0 or negative, the caller will attempt claiming the lock, if there is no owner, it would claim successfully, otherwise it would return immediately and throw exception to indicate who is the current owner.
Reader Configuration Settings
General Settings
- readLACLongPollTimeout: The long poll timeout for reading LastAddConfirmed requests, in milliseconds. The default value is 1 second. It is typically recommended to tune approximately with the request arrival interval. Otherwise, it would end up becoming unnecessary short polls.
ReadAhead Settings
This section describes the settings related to readahead in DL readers.
- enableReadAhead: Flag to enable read ahead in DL readers. It is enabled by default.
- readAheadMaxRecords: The maximum number of records that will be cached in readahead cache by the DL readers. The default value is 10. A higher value will improve throughput but use more memory. It should be tuned properly to avoid jvm gc if the reader cannot keep up with the writing rate.
- readAheadBatchSize: The maximum number of entries that readahead worker will read in one batch. The default value is 2. Increase the value to increase the concurrency of reading entries from bookkeeper. It is recommended to tune to a proper value for catching up readers, not to exhaust bookkeeper's bandwidth.
- readAheadWaitTimeOnEndOfStream: The wait time if the reader reaches end of stream and there isn't any new inprogress log segment, in milliseconds. The default value is 10 seconds.
- readAheadNoSuchLedgerExceptionOnReadLACErrorThresholdMillis: If readahead worker keeps receiving NoSuchLedgerExists exceptions when reading LastAddConfirmed in the given period, it would stop long polling LastAddConfirmed and re-initialize the ledger handle and retry. The threshold is in milliseconds. The default value is 10 seconds.
Reader Constraint Settings
This section describes the constraint settings in DL reader.
- ignoreTruncationStatus: The flag whether to ignore truncation status when reading the records. By default, it is false. The readers will not attempt to read a log segment that is marked as Truncated if this setting is false. It can be enabled for tooling and troubleshooting.
- alertPositionOnTruncated: The flag whether we should alert when reader is positioned on a truncated segment. By default, it is true. It would alert and fail the reader if it is positioned at a Truncated log segment when the setting is true. It can be disabled for tooling and troubleshooting.
- positionGapDetectionEnabled: The flag whether to enable position gap detection or not. This is a very strict constraint on reader, to prevent readers miss reading records due to any software bugs. It is enabled by default.
Idle Reader Settings
There is a mechanism to detect idleness of readers, to prevent reader becoming stall due to any bugs.
- readerIdleWarnThresholdMillis: The warning threshold of the time that a reader becomes idle, in milliseconds. If a reader becomes idle more than the threshold, it would dump warnings in the log. The default value is 2 minutes.
- readerIdleErrorThresholdMillis: The error threshold of the time that a reader becomes idle, in milliseconds. If a reader becomes idle more than the threshold, it would throw IdleReader exceptions to notify applications. The default value is Integer.MAX_VALUE.
Scan Settings
- firstNumEntriesEachPerLastRecordScan: Number of entries to scan for first scan of reading last record. The default value is 2.
- maxNumEntriesPerReadLastRecordScan: Maximum number of entries for each scan to read last record. The default value is 16.
Tracing/Stats Settings
This section describes the settings related to tracing and stats.
- traceReadAheadDeliveryLatency: Flag to enable tracing read ahead delivery latency. By default it is disabled.
- metadataLatencyWarnThresholdMs: The warn threshold of metadata access latency, in milliseconds. If a metadata operation takes more than the threshold, it would be logged. By default it is 1 second.
- dataLatencyWarnThresholdMs: The warn threshold for data access latency, in milliseconds. If a data operation takes more than the threshold, it would be logged. By default it is 2 seconds.
- traceReadAheadMetadataChanges: Flag to enable tracing the major metadata changes in readahead. If it is enabled, it will log the readahead metadata changes with precise timestamp, which is helpful for troubleshooting latency related issues. By default it is disabled.
- enableTaskExecutionStats: Flag to trace long running tasks and record task execution stats in the thread pools. It is disabled by default.
- taskExecutionWarnTimeMicros: The warn threshold for the task execution time, in micros. The default value is 100,000.
- enablePerStreamStat: Flag to enable per stream stat. By default, it is disabled.
Feature Provider Settings
- featureProviderClass: The feature provider class. The default value is DefaultFeatureProvider, which disable all the features by default.
