Ethocin for some reason always interested me, and a year ago when I passed up the chance to acquire some, I was very saddened. Recently, though, I was able to get my hands on a gram for experimentation.
This particular venture was between my significant other of several years, and myself in our home. I measured out somewhere in the mid 20mg range with my scale, I just don't remember the exact dosage, M took about a small amount less than I (It should probably be noted that the form of the compound we were using was the fumarate salt which increases the weight needed by 33%). The doses were capped then swallowed in the evening around eight, at least two hours after our last meal.
It takes about an hour and a half for the effects to really begin to manifest themselves, and it starts out with a light buzz in the body, then a lightness of the body and mind. Right before the come up, we packed a bowl of some Herb to smooth out the transition into the new territory and sat around talking to each other. Tripping together really brings the two of us much closer and allows for so much more understanding than is usually afforded. This experience was great for that, we sat in our living room with our cats joking and laughing for nearly the entirety of the experience. It felt like all of our concerns and worries that get between us and move us apart spiritually, mentally, and physically were all dissolved by the ethocin with such simple ease as an ocean wave will wash away sand.
At one point, we noticed that each of our cats were sitting on either of our sides like a pair of dutiful sentinels watching over our safety.  Now we gotta babysit their asses!' It was very strange and almost unnerving because it seemed like they were trying to protect of us from something we couldn't see, but were obviously vulnerable to.
At one other point in the night, I had begun to space out and closed my eyes. The detail and vibrance of the CEV's was amazing! Three dimensional gridworks and landscapes began to form and I began to descend down into them. As I got further down, I felt a similar sensation to entering the Void on 5-MeO-DMT and I could feel my body slowing down. I felt my skin conductance decrease, my heart rate was slowing, my mind felt still, and my breathing had all but stopped. In my mind I was descending through the gridded, digital landscape and floating in free air were two enormous biological hearts beating. At this point I could see myself far far far down drifting ever further down between these two hearts. I felt like I was moving closer and closer to the death state as my body became less and less animate. It was about then that my cat apparently left his spot across the room and made his way with urgency over to me and started persistently tapping me with his paw to arouse me.
As soon as I emerged from my state, M was looking at me with astonishment of what just happened, because as soon as I snapped out my cat lost all interest in gaining my attention. We hypothesized that as I felt my energy transcending my physical state, there must have been an energy fluctuation that was perceived by my diligent feline who then became concerned with me.
Overall, ethocin is a very friendly feeling molecule with little in the way of body load, save a few tremors at the higher doses. It took about 90 minutes to two hours come up, and there is no real definable peak, rather a four hour period of peaking, then not peaking, then peaking, etc. Sleep typically comes moderately easy with a renewed, refreshed feeling the next day.

Localization refers to the problem of pinpointing your location. The GPS is one of the most important technologies we have today. We can do thousands of different things by simply knowing where we are.
A similar logic applies to climbing. I imagine climber localization will have dozens of applications in the future. This topic deals with the localization technology itself, not the applications.
The topic will cover anything related to localization on a climbing wall. My vision for the topic is discussed in more detail in the first article.

Report for peroidically hibernation of Nvidia DGX 230 on Aug. 11, 2018
| Date: | Aug 11, 2018 |

Contents
Problem statement
- What is it?: We assume that this problem is caused by the hibernation of the graphics cards.
- How does it happen?: This problem occurs periodically. Every week it would occur for about once. It is not due to some special applications, because even when there is no burden on GPU, it still happens.
- What does it cause?: Here are some phenomenons when the problem appears:
- Cannot turn on the screen: The screen of DGX would be kept off. Whatever we do (like move the mouse or type something with the keyboard), the screen would not be turned on. However, we could still get access to the device by remote accessing (like using Putty).
- Cannot use nvida apps: Like
nvidia-smi
,nvidia-docker run
. It would return an error likeGPU is lost
. However, some commands are still accessible, likenvidia-docker images
. - Cannot exit from the container: If we are running a container by docker when the problem occurs, we could still use the container normally (except some processes that need GPU). But if we type
exit
inside the container, the terminal would be freezed. - Process on GPU would be freezed: If we are running any process that needs the GPU when the problem occurs, that process would be freezed. We could not terminate it by
terminate
orkill
. - A core would be fully occupied (not verified): It seems that when this problem occurs, one CPU core (among 40 logical cores) would be fully occupied. But we could not find which application is occupying it.
- How to solve it?: Now every time it happens, we need to restart the machine and everything would be recoverd. But after about one week, it happens again.
- Why we need to solve it?: Many of our programs need to be runned for a long time (several days), we could not take the risk of restarting our testing program due to the hibernation.
Problem records
Screenshots
This problem could be detected by running nvidia-smi
. For example, if we are running watch nvidia-smi
, we could find this problem if the returned message is changed like this:
| nvidia-smi tells us that GPU is lost |
|---|
Here we show a screenshot when the problem occurs. This screen shot is captured inside the container, i.e. a VNC remote desktop provided by the container. We are running a testing program that only uses CPU, so we could see that the CPU is occupied and that program keeps running normally. However we could not get access to the GPU now.
| A whole screenshot when the problem happens |
|---|
Nvidia bug reports
Run this command outside the docker (by remote accessing, we have mentioned that although we could not turn on the screen, we could still get access to the Bash by remote accessing), then we would get a full record of the hardware:
$ sudo nvidia-bug-report.sh
To help us detect what happens and what makes it different when the problem occurs, we run the command for twice. One is during the hibernation and the other is in the normal state (where the GPU is working correctly). The comparison of two reports is shown as follows:
The left side is the report of a normal state, the right one is the report when the problem happens. You could download the comparison of the reports by this link:
Or you can use the following links to download the original txt
reports directly:
Nvidia healthy report
Follow the instructions here:
We use this command to collect the system status firstly:
$ sudo nvsysinfo
This command would dump a file with a name like /tmp/nvsysinfo-timestamp.random-number.out
. No more information is given.
Then, call this command,
$ sudo nvhealth &> nvhealth.log
This command would also dump a file with a name like /tmp/nvhealth-log.random-string.jsonl
. And the printed information would be dumpled into nvhealth.log
.
We have run these commands in both bug state and normal state respectively. The comparison of the nvhealth.log
is shown as follows:
You can only download the comparison report here:
We have collected all dumped files in a zipped file. The file name table is as follows:

In the Java programming language, arrays are objects. All methods of class Object may be invoked on an array.
Scala arrays correspond one-to-one to Java arrays. For example, a Scala array Array[Int]
is
represented as a Java int[]
.
An array type is written as the name of an element type followed by some number of empty pairs of square brackets []. The number of bracket pairs indicates the depth of array nesting.
{% highlight java %} // Annotations is not included in this post dataType[] arrayRefVar; // preferred way. or dataType arrayRefVar[]; // accommodate C/C++ style {% endhighlight %}An array is created by an array creation expression or an array initializer
{% highlight java %} // Array creation expression dataType[] arrayRefVar = new dataType[arraySize]; // Array Initializer dataType[] arrayRefVar = {value0, value1, ..., valuek}; {% endhighlight %} ScalaThe element type of an array may be any type, whether primitive or reference.
In particular:An array's length is not part of its type.
The supertype relation for array types is not the same as the superclass relation.
The direct supertype of Integer[] is Number[], but the direct superclass of Integer[] is Object. This does not matter in practice, because Object is also a supertype of all array types.
{% highlight java %} byte[] rowvector, colvector, matrix[]; is equivalent to: byte rowvector[], colvector[], matrix[][]; int a, b[], c[][]; is equivalent to: int a; int[] b; int[][] c; {% endhighlight %}Arrays must be indexed by int values; An attempt to access an array component with a
long index value results in a compile-time error.
All array accesses are checked at run time; an attempt to use an index that is less than zero or greator than
or equal to the length of the array causes an ArrayIndexOutOfBoundsException
to be thrown.
Array[T]
where T
is a type parameter or abstract type.
Array[T]
where a Seq[T]
is required.
Given that Scala arrays are reprresented just like Java arrays, how can these additional features be supported in Scala?
There is an implicit "wrapping" conversion between arrays and instances of class scalla.collection.mutable.WrappedArray, which is a subclass of Seq.
{% highlight scala %} scala> val a1 = Array(1, 2, 3) a1: Array[Int] = Array(1, 2, 3) scala> val seq: Seq[Int] = a1 seq: Seq[Int] = WrappedArray(1, 2, 3) scala> val a2: Array[Int] = seq.toArray a2: Array[Int] = Array(1, 2, 3) scala> a1 eq a2 res0: Boolean = true {% endhighlight %}There is another implicit conversion that gets applied to arrays. This conversion simply "adds" all sequence methods to arrays but does not turn the array itself into a sequence. "Adding" means that the array is wrapped in another object of type ArrayOps which supports all sequence methods. Typically, this ArrayOps object is short-lived; it will usually be inaccessible after the call to the sequence method and its storage can be recycled. Normally, you'd never define a value of class ArrayOps. You'd just call a Seq method on an array.
{% highlight scala %} scala> val a1 = Array(1, 2, 3) a1: Array[Int] = Array(1, 2, 3) scala> val seq: Seq[Int] = a1 seq: Seq[Int] = WrappedArray(1, 2, 3) scala> seq.reverse res0: Seq[Int] = WrappedArray(3, 2, 1) scala> val ops: collection.mutable.ArrayOps[Int] = a1 ops: scala.collection.mutable.ArrayOps[Int] = [I(1, 2, 3) scala> ops.reverse res1: Array[Int] = Array(3, 2, 1) {% endhighlight %}The ArrayOps object gets inserted automatically by the implicit conversion.
{% highlight scala%} scala> a1.reverse res3: Array[Int] = Array(3, 2, 1) equivalent to scala> intArrayOps(a1).reverse res5: Array[Int] = Array(3, 2, 1) {% endhighlight %}The ArrayOps conversion has a higher priority than the WrappedArray conversion.
How about genericity?
TO DO
The component type of an array may itself be an array type.
There are some situation in which an element of an array can be an array: if the element type is Object or Cloneable or java.io.Serializable, then some or all of the elements may be arrays because any array object can be assigned to any variable of these types.
Copying Arrays:
{% highlight java %} public static void arraycopy(Object src, int srcPos, Object dest, int destPos, int length) {% endhighlight %} {% highlight java %} class ArrayCopyDemo { public static void main(String[] args) { char[] copyFrom = { 'd', 'e', 'c', 'a', 'f', 'f', 'e', 'i', 'n', 'a', 't', 'e', 'd' }; char[] copyTo = new char[7]; System.arraycopy(copyFrom, 2, copyTo, 0, 7); System.out.println(new String(copyTo)); } } {% endhighlight %} {% highlight java %} class ArrayCopyOfDemo { public static void main(String[] args) { char[] copyFrom = {'d', 'e', 'c', 'a', 'f', 'f', 'e', 'i', 'n', 'a', 't', 'e', 'd'}; char[] copyTo = java.util.Arrays.copyOfRange(copyFrom, 2, 9); System.out.println(new String(copyTo)); } } {% endhighlight %}Array Manipulations
java.util.Arrays Some other useful operations provided by methods in the java.util.Arrays class, are: Searching an array for a specific value to get the index at which it is placed (the binarySearch method). Comparing two arrays to determine if they are equal or not (the equals method). Filling an array to place a specific value at each index (the fill method). Sorting an array into ascending order. This can be done either sequentially, using the sort method, or concurrently, using the parallelSort method introduced in Java SE 8. Parallel sorting of large arrays on multiprocessor systems is faster than sequential array sorting. If the type of the value being assigned is not assignment-compatible with the component type, an ArrayStoreException is thrown. {% highlight java %} class Point { int x, y; } class ColoredPoint extends Point { int color; } class Test { public static void main(String[] args) { ColoredPoint[] cpa = new ColoredPoint[10]; Point[] pa = cpa; System.out.println(pa[1] == null); try { pa[0] = new Point(); } catch (ArrayStoreException e) { System.out.println(e); } } } {% endhighlight %} This program produces the output: {% highlight java %} true java.lang.ArrayStoreException: Point {% endhighlight %}use leetcode and hackerrank problems to illustrate above content.But only links to other posts

Wingman was the most popular Operation Hydra Event, and will remain available for players with a few changes. Wingman matchmaking will feature community favorite Wingman maps from Operation Hydra, and players will now be able to select individual maps instead of having one randomly selected. Additionally, players will now have a Wingman skill group that will be used exclusively when matchmaking in Wingman.
With the War Games format, players were able to select their desired game mode and could select a new experience after a few rounds. We’re keeping the War Games format, and folding in some of CS:GO’s alternative game modes into that category. In the War Games tab, players will be able to select Arms Race, Demolition, or the most popular War Game of Operation Hydra, Flying Scoutsman!
The Competitive Matchmaking map pool previously contained every map in CS:GO, making it difficult for new or recently updated maps to stand out among the crowd of available options and generating poor matches as a result. To address these problems, the least-played maps will no longer be featured in official Competitive Matchmaking. Over time, promising new or updated maps will enter the map pool, and less played maps will continue to be removed.
To give players’ favorite maps a better chance of winning the vote, maps in the Casual game mode have been redistributed into new groups based on overall playtime. Some of the least-played maps have been removed from the pool, and some new maps have been added: Austria, Shipped, Agency, and Insertion. As with the Competitive Matchmaking map pool, the Casual map pool and map groups will be updated over time.
We’re excited to announce CS:GO’s next Major Championship Series will be hosted by ELEAGUE, with Playoffs taking place in Boston, January 26-28.
Regional Champions
Two teams from Regional Minor Championships in the Americas, Asia, Europe, and CIS regions will advance as contenders at the ELEAGUE Major Qualifier.
Asia – October 26-29, Seoul
CIS – October 26-29, Bucharest
Europe – November 2-5, Bucharest
Americas – November 2-5, Toronto
Contenders, Challengers, Legends
For the first time, the CS:GO Major Qualifier, Group Stage, and Playoffs will take place across consecutive weekends, with all stages of the event streamed live on Twitch, ELEAGUE.com and YouTube.
It starts with the ELEAGUE Major Qualifier (Jan. 12-15) and ELEAGUE Major Group Stage (Jan. 19-22) at the ELEAGUE Arena in Atlanta. The event culminates with the Playoffs (Jan. 26-28) at the Agganis Arena in Boston, with the winner taking home their share of the $1,000,000 prize pool and becoming CS:GO Major Champions!


About Me
Who am I? I would say that I am the person who believe that we become smarter people by resolving prolems, but not by escaping from them out of fear. Having said this I would say that I really enjoy coding. Why? Because of at least three reasons. First, I just love it. Secondly, being Software Developer always pushes me to learn and develop myself as personality. Thirdly, there is no way to escape from problems while coding, but the only way to success is to resolve them.
Now a few words about my background. Originally I'm from Ukraine. Having moved to the US more than 8 years ago. Started my career as QA Engineer and worked for a while. However, I felt that it was not enough for me. So, then I decided to become Software Developer and now enjoy by being whom I am. Now, I'm looking for new opportunities as Full Stack Developer.


Optimization Part 1
Optimizing w for logistic regression
Recall the minimizer of the logistic regression algorithm:
$$
\min_w \sum_{(x^i, y^i \in D)} log(1 + e^{-y^i w^T \phi (x^i)}) = f(w)
$$
We know that for a convex problem, we have hit a minimizer if the gradient is 0.
We can use gradient descent to iteratively find smaller and smaller gradients till we get as close to 0 as possible, providing a relatively optimal minimizer.
Many ML optimization problems are solved with a variant of gradient descent. The derived minimzer gradient is:
$$
\nabla_w f(w) = \sum_{(x^i, y^i) \in D} \frac{-y^i \phi(x^i) e^{-y^i w^T \phi(x^i)}}{1 + e^{-y^i w^T \phi(x^i)}}
$$
Pseudocode:
- Initialize t=0, \(w_t\), and stepsize \(\alpha\)
- Compute gradient \(g_t = \nabla_w f(w_t) \)
- Update parameters \(w_{t+1} \leftarrow w_t - \alpha g_t \)
- Update \(t \leftarrow t+1 \)
Consider what happens if \(f(w)\) isn't convex, as in there are bumps in the function?
Figure 1. Possible min points of \(f(w)\)
Gradient descent will target all 3 of those points since the gradients at those points are all 0, when we only want to target the global minimizer. We will attempt to solve this problem through the rest of this lecture and the next one.
Convex Sets
Convex sets are useful for defining convex functions, which we need in order to deterine if gradient descent can be reliably used to find the minimizer of a loss function. A set is convex if it contains all line segments that can be formed by any 2 points within the set.
Figure 2. Convex Set Example
The set on the left is not convex because there exists 2 points in the set where the line between them is not inside the set. The set on the right is convex because all lines formed between any 2 points lie within the set. More formally, \(C \subseteq \mathbb{R}^d\) is convex when $$\{x,y\} \subseteq C \Rightarrow [x,y] \subseteq C$$ $$[x,y] = \{\alpha x + (1-\alpha)y : \alpha \in [0,1]\}$$
Convex Hull
A convex hull is the smallest set that contains given data points.
Figure 3. Convex Hull Example
In the example above, the white points are the given points. And the convex hull is the set formed by the purple lines, as it a rubber band was put around the points.
For a non-infinite set \(S = (x_1, x_2, ... x_k)\), the convex hull is simply all convex combinations of the points. In other words, it's the intersection of all lines formed between all points in \(S\). More formally, $$conv(S) = \{ \sum_{i=1}^k \alpha_i x_i : \alpha_i \geq 0, \sum_{i=1}^k \alpha_i = 1 \}$$
Convex Function
Recall from calculus the epigraph of a function. It is defined as a set of all the points and values of the function less than some line. $$ epi(f) = \{(x,r) : x \in \mathbb{R}^d, r \in \mathbb{R}, f(x) \leq r\} $$ The intuition is we can think of it as water filling the function where the set formed by the water is the set formed by the epigraph function as can be seen in Figure 4. We are able to formally define a convex function by a convex set.
Theorem: f is a convex function when epi(f) is a convex set.
Figure 4. Convex Function Waterfill
As we can see, the shaded area is epi(f) and the graph on the right is non-convex because epi(f) is non-convex. Alternatively, based on the epigraph theorem, we can algebraically define that for any \(x,y \in \mathbb{R}^d\) and \(\alpha \in [0,1]\), f is a convex function when... $$ f(\alpha x + (1- \alpha)y) \leq \alpha (x) + (1-\alpha)f(y) $$ In other words, f is a convex function if f of a linear combination of points is less than a convex combination of function values. In the figure below, we choose points \(x,y \in \mathbb{R}^d\). In the left graph, we can see that the \(f(x)\) is always underneath the line formed by \(x\) and \(y\), meaning it is convex. In the right graph, the opposite is true, meaning it is non-convex.
Figure 5. Algebraic Form of Epigraph Theorem Visualized
Convex Loss
Convexity indicates that there are no bumps on the function, and therefore, gradient descent works to find the minimizer. To review squared and logistic loss:
Figure 6. Squared loss vs logistic loss
Informally, we can clearly see that both quadratic loss and log loss are convex (proven formally, they are!). We can also see that 0/1 loss is non-convex.
Various Ways to Check Convexity
The first way is the Line Segment Method described above.
For any \(x,y \in \mathbb{R}^d\) and \(\alpha \in [0,1]\), f is a convex function when... $$ f(\alpha x + (1- \alpha)y) \leq \alpha f(x) + (1-\alpha)f(y) $$ The second way is the Derivatives Method:
For all \(x,y\), $$ f(y) \geq f(x) + \nabla f(x)^T(y-x) $$ Intuitively, this is simply saying that if \(y \geq x\), then the gradient at \(y\) must be larger than the gradient at \(x\).
Figure 7. Visualization of Derivatives Method
Levels of Convexity
There are 2 levels of convexity that should be noted. There is strict convexity, where the inequality defining the convexity of a function is strict: $$ f(\alpha x + (1- \alpha)y) < \alpha f(x) + (1-\alpha)f(y) $$ Graphically, this means that the line between points \(x\) and \(y\) remains strictly above the graph, it cannot be equivalent to the graph at any point. Logistic loss \(ln(1+e^{-z})\) is strictly convex.
This is also \(\lambda\)-strong convexity: $$ f(\alpha x + (1- \alpha)y) \leq \alpha f(x) + (1-\alpha)f(y) - \frac{\lambda \alpha (1-\alpha)}{2}||x-y||^2 $$ In this case, there is a quadratic gap between function values and the line formed by \(x\) and \(y\). The intuition is that we can lower bound the function by a quadratic. Squared loss \(\frac{1}{2}(1-z)^2 \) is 1-strongly convex.

Tullow’s shares go down by 50 percent as CEO resigns over poor performance in Ghana
by Magdalene Teiko LarnyohThe shares of Tullow Oil Plc on the London Stock Exchange (LSE) dropped by over 50% as its CEO, Paul McDade resigned due to the poor performance in its Ghana operations.
The resignation of CEO, Paul McDade, comes after the company’s head of exploration Angus McCoss also quit on Monday.
Tullow Oil could not meet its production targets because of technical problems at Jubilee and a delay in the completion of a well at the TEN fields.
Tullow is the lead partner of the Jubilee and TEN fields.
The oil company has seen some turbulent times in recent times in an attempt to develop oil fields in Uganda and Guyana.
Due to the challenges the company is facing, Tullow has announced that it has revised its key production figures stating that oil production is expected to hover around 87,000 barrels of oil per day (bopd) this year.
Meanwhile, the lower production in 2020 is to be between 70,000 and 80,000 (bopd), as it undertook a review of its production performance issues.
Tullow suspended its dividend with the aim of generating more cash to support future investment plans and current explorations.
“The board has, however, been disappointed by the performance of Tullow’s business and now needs time to complete its thorough review of operations,” Executive Chairman Dorothy Thompson said.
Meanwhile, Tullow said it has started a process to find a new group chief executive.


Mission statement
In short: help developers manage dependencies and multi-configuration builds.
Based on a simple multi-version dependencies manager (built on top of npm), the xPack project aims to provide a set of cross-platform tools to manage, configure and build complex, modular, multi-target (multi-architecture, multi-board, multi-toolchain) projects, in a reproducible way, with an emphasis on C/C++ and bare-metal embedded projects.
The expected benefits are more efficient code sharing and reusing during the life cycle of libraries and applications.
xPacks overview
Did you ever face the situation when building a perfectly fine and functional project suddenly failed after upgrading the system? If so, xPacks may help you.
xPacks are general purpose versioned software projects, built on top of the highly successful npm packages in the Node.js JavaScript ecosystem. xPacks do not introduce a new package format, but use exactly the same format as npm packages, and can be stored in the same repositories.
By design the xPacks tools are multi-version, which means not only that packages can have multiple versions, but they can be installed in parallel, each project/configuration having its own set of dependencies, thus upgrading the system no longer impacts the project.
Although the current focus is on C/C++, most of the tools are language agnostic and can be used with other programming languages as well.
Based on the installed content, there are currently two types of xPacks: source and binary:
- source xPacks are packages that install source files, generally libraries
- binary xPacks are packages that install binary/executable files, generally tools used during the build process, like toolchains, builders, etc.
For more details, read the xPack 101 page.
The entire xPack project is split amongst several groups, published as separated GitHub organisations (xpack, xpack-dev-tools, micro-os-plus, xpack-3rd-party).
xPack Core Tools

WHEN HARRY MET SALLY... Reviewed by David N. Butterworth Copyright 1989 David N. Butterworth/The Summer Pennsylvanian
If imitation is the sincerest form of flattery, then Woody Allen should feel sincerely flattered by WHEN HARRY MET SALLY..., Rob (THE PRINCESS BRIDE) Reiner's latest romantic comedy. The comparisons between this film and Allen's ANNIE HALL are inevitable -- Reiner almost seems to be inviting them in fact. But, whilst it doesn't quite match that film stylistically, it does come awfully close on occasions.
The film stars Billy (RUNNING SCARED, MEMORIES OF ME) Crystal and Meg (INNERSPACE, D.O.A.) Ryan in the title roles. They are two mismatched individuals -- she an aspiring journalist, he a successful political consultant -- who meet and fall in love, yet don't fully realize it until twelve years afterwards.
Prior to that revelation, the two of them bump into each other on two separate occasions and end up discussing love, sex, and marriage. Harry's philosophy on life is that a man can never be friends with a woman to whom he's attracted because "the sex thing always gets in the way." Nevertheless he finds Sally "empirically" attractive. What follows is a love/hate relationship in which the hate often outweighs the love.
When Harry and Sally meet for the third time in twelve years, it's in a book store. "There's a man staring at you in Personal Growth," comments Sally's girlfriend Marie. She's played by Carrie Fisher of Princess Leia fame and, together with Bruno Kirby as Harry's best friend Jess, provides the two leads with staunch acting support.
The screenplay, by Nora (HEARTBURN) Ephron -- who also serves as the film's Associate Producer -- is well-structured but misses some of the insight and astuteness which garnered ANNIE HALL an Academy Award back in 1977, the year this new film opens, ironically. Nevertheless, it remains consistently funny, with writing of the "In a city of 8 million people, I have to run into my ex-wife!" calibre.
But the nicest surprise is Meg Ryan's performance as Sally. Frankly, it's a gem. Although not known for her comedic talents, director Reiner certainly brings them out in this movie. Working shoulder-to-shoulder with Crystal, a comedian of considerable skill, Ryan is never out of her depth and often outshines him.
Crystal's rendering of the smug, know-it-all Harry often drifts into some of the characterizations which populate his stand-up routines, and it's distracting at times. His character doesn't develop much throughout the course of the movie. In fact, one of the few things that does change about Harry is the length of his sideburns.
Sally, on the other hand, develops significantly. The scene in which she learns that her ex-boyfriend has recently married is a joy to watch. Ryan's red-eyed, rag doll hysterics are spot on and beautifully realized. And there's a scene in a sandwich bar which is an absolute riot.
But to return to the parallels between this film and ANNIE HALL...
WHEN HARRY MET SALLY... opens with a bouncy, nostalgic jazz tune reminiscent of Woody Allen's later films. Reiner also intersperses the action with documentary-style interviews -- a common Woody Allenism -- between married couples. Seated against a pastel backdrop, they discuss how they met and how, after all these years, they're still together. And the film's subject matter itself -- New Yorker's neuroses about sex, marriage and relationships -- is prime Woody Allen territory.
Moviegoers who don't particularly like Woody Allen, but enjoy his brand of humor, might get a big kick out of WHEN HARRY MET SALLY.... At its worst, the film is simply derivative. But at its best, it holds its own against some of that director's finest work.

Hi All
I'm using the SCT-013-000 100A:50mA Current transformer. I've been trying the tutorials and schematics with no luck. I want to connect this CT to the Arduino to sense load (current). I need to convert the mA output to a dc voltage to be sensed. When I test the CT, the mA output is correct and linear as expected.
1. Current sensing resistor
When I try passing the current over a resistor to sense the voltage I get 0V dc. I tried various different resistance values (33,100,1k etc) and no change to the output. I've tried the resistors on a breadboard and soldered them to a veroboard - no difference. This should follow Ohms Law and produce a voltage output, Vout = Iout x Resistor
(Circuit is attached)
2. Tutorial
I also tried the Open Energy Tutorial and the voltage stays fixed around 2.5V dc, irrespective of the load I apply via the CT. (http://openenergymonitor.org/emon/buildingblocks/ct-sensors-interface). I've tried loads up to 30A with no change.
Please could you assist me and tell me what I'm doing wrong?
Thanks
Re: CT Voltage sensing
The ADC in your Arduino works over the range 0 - 5V, so the output from your CT needs to be centred within this range. Otherwise, you will only see half of the signal. The recommended interfacing circuit is as you have noted at:
http://openenergymonitor.org/emon/buildingblocks/ct-sensors-interface
With this circuit in place, values from the ADC should be centred around the mid-point (512) with the AC component showing up as variations on either side of this. When the AC signal occupies the full range of the ADC, the data values will range from 0 to 1023. The measurement range of the system (in kW) is determined by the size of the burden resistor.
You can check the operation of your circuit using a simple sketch which repeatedly takes ADC samples and prints their value. There are a couple of such sketches at:
http://openenergymonitor.org/emon/node/789
Re: CT Voltage sensing
Have you tried the sketch at the bottom of that Building Blocks article you link to? I strongly suspect - given that you don't tell us how you are trying to measure the transformer output - that all you have is v = analogRead(input_pin). That will measure the voltage at one instant, but remember that the output of a transformer - both voltage and current transformers - is alternating, and you need to do the sums in that sketch, and those are roughly the same sums that your multimeter does, to read a sensible current.
Read more in Building Blocks and it is all explained for you.
Re: CT Voltage sensing
The issue is before I can even get to the sketch.
The output voltage does not change from 2.5V dc irrespective of the primary load I apply to the transformer.
I built the circuit as per http://openenergymonitor.org/emon/buildingblocks/ct-sensors-interface but the voltage to analogue pin stays at 2.5V dc.
Why would the output voltage not change?
Re: CT Voltage sensing
@cpaw,
You mentioned that the sketch is not even running yet, so how are you measuring the voltage on the ADC pin?
If you are using a multimeter, if you have selected 'DC', you will see only 2.5V displayed.
[Edit - RW]
And even if you have selected "AC", you still will not necessarily read the result that you are expecting because the voltage you want is sitting on top of the 2.5 V that you are measuring. Look at and study the diagram on that Building Blocks page.

I am originally from Wisconsin and moved to California in 2014.
My family and I moved here for better education for our daughters, better opportunities and the really good weather.
Volunteering and helping others are important to me.
I continue to give back to the community as an active member in the Eastshore-PTA, volunteer for Girl Scouts and an active member for my church.
I have been in the engineering field with my associates in electrical engineering since 2006.
Over the years engineering has fueled my desire to become a programmer .
To build and program electronics has become my biggest passion as I build my software development skills.
The LearningFuze boot camp program has allow me to pursue my passion as a software developer.
This was also one of the most challenging and satisfying accomplishments I have achieved.
Every day was a new challenge and something new to learn.
Not just in programming but in team building skills, communication and other tools to use to become an effective programmer.
All the work and hours I have dedicated prepared me for a life in software development.
For example, out of 16 projects submitted, mine was 1 of 4 that made the cut as one of the final team projects.
As a team lead I managed projects with effective communication.
For each team project, we would collect feedback and opinions from the team with constant communication on progress and changes as we designed and created the applications.
This allowed us to build applications effectively in extremely short time frames.
With everything I have learned through LearningFuze I am excited to see what I will accomplish as I grow my programming skills.

SCENE. Friar Laurence's cell.
(Enter FRIAR LAURENCE and PARIS)
FRIAR LAURENCE
On Thursday, sir? the time is very short.
PARIS
My father Capulet will have it so;
And I am nothing slow to slack his haste.
FRIAR LAURENCE
You say you do not know the lady's mind:
Uneven is the course, I like it not.
PARIS
Immoderately she weeps for Tybalt's death,
And therefore have I little talk'd of love;
For Venus smiles not in a house of tears.
Now, sir, her father counts it dangerous
That she doth give her sorrow so much sway,
And in his wisdom hastes our marriage,
To stop the inundation of her tears;
Which, too much minded by herself alone,
May be put from her by society:
Now do you know the reason of this haste.
FRIAR LAURENCE
[Aside] I would I knew not why it should be slow'd.
Look, sir, here comes the lady towards my cell.
(Enter JULIET)
PARIS
Happily met, my lady and my wife!
JULIET
That may be, sir, when I may be a wife.
PARIS
That may be must be, love, on Thursday next.
JULIET
What must be shall be.
FRIAR LAURENCE
That's a certain text.
PARIS
Come you to make confession to this father?
JULIET
To answer that, I should confess to you.
PARIS
Do not deny to him that you love me.
JULIET
I will confess to you that I love him.
PARIS
So will ye, I am sure, that you love me.

JULIET
The tears have got small victory by that;
For it was bad enough before their spite.
PARIS
Thou wrong'st it, more than tears, with that report.
JULIET
That is no slander, sir, which is a truth;
And what I spake, I spake it to my face.
PARIS
Thy face is mine, and thou hast slander'd it.
JULIET
It may be so, for it is not mine own.
Are you at leisure, holy father, now;
Or shall I come to you at evening mass?
FRIAR LAURENCE
My leisure serves me, pensive daughter, now.
My lord, we must entreat the time alone.
PARIS
God shield I should disturb devotion!
Juliet, on Thursday early will I rouse ye:
Till then, adieu; and keep this holy kiss.

FRIAR LAURENCE
Ah, Juliet, I already know thy grief;
It strains me past the compass of my wits:
I hear thou must, and nothing may prorogue it,
On Thursday next be married to this county.
JULIET
Tell me not, friar, that thou hear'st of this,
Unless thou tell me how I may prevent it:
If, in thy wisdom, thou canst give no help,
Do thou but call my resolution wise,
And with this knife I'll help it presently.

Be not so long to speak; I long to die,
If what thou speak'st speak not of remedy.
FRIAR LAURENCE
Hold, daughter: I do spy a kind of hope,
Which craves as desperate an execution.
As that is desperate which we would prevent.
If, rather than to marry County Paris,
Thou hast the strength of will to slay thyself,
Then is it likely thou wilt undertake
A thing like death to chide away this shame,
That copest with death himself to scape from it:
And, if thou darest, I'll give thee remedy.

FRIAR LAURENCE
Hold, then; go home, be merry, give consent
To marry Paris: Wednesday is to-morrow:
To-morrow night look that thou lie alone;
Let not thy nurse lie with thee in thy chamber:
Take thou this vial, being then in bed,
And this distilled liquor drink thou off;
When presently through all thy veins shall run
A cold and drowsy humour, for no pulse
Shall keep his native progress, but surcease:
No warmth, no breath, shall testify thou livest;
The roses in thy lips and cheeks shall fade
To paly ashes, thy eyes' windows fall,
Like death, when he shuts up the day of life;
Each part, deprived of supple government,
Shall, stiff and stark and cold, appear like death:
And in this borrow'd likeness of shrunk death
Thou shalt continue two and forty hours,
And then awake as from a pleasant sleep.
Now, when the bridegroom in the morning comes
To rouse thee from thy bed, there art thou dead:
Then, as the manner of our country is,
In thy best robes uncover'd on the bier
Thou shalt be borne to that same ancient vault
Where all the kindred of the Capulets lie.
In the mean time, against thou shalt awake,
Shall Romeo by my letters know our drift,
And hither shall he come: and he and I
Will watch thy waking, and that very night
Shall Romeo bear thee hence to Mantua.
And this shall free thee from this present shame;
If no inconstant toy, nor womanish fear,
Abate thy valour in the acting it.
JULIET
Give me, give me! O, tell not me of fear!
FRIAR LAURENCE
Hold; get you gone, be strong and prosperous
In this resolve: I'll send a friar with speed
To Mantua, with my letters to thy lord.
JULIET
Love give me strength! and strength shall help afford.
Farewell, dear father!

Streaming updates: Spotify free comes to Alexa speakers, Sling TV works with Nest Hub
by Brad LinderJust a few days after Amazon announced that its free, ad-supported music streaming services was now available on devices other than Echo smart speakers, rival Spotify has announced that its ad-supported music streams are now available on Echo speakers… along with just about anything else that supports the Alexa voice service, including Amazon Fire TV products.
It’s just one of a number of recent announcements involving the ability to use streaming services on new platforms.
Here’s a brief roundup.
First of all, Spotify has announced its free service is now available on for:
- Alexa devices
- Bose wireless speakers
- Sonos wireless speakers (including the IKEA SYMFONISK WiFi speaker)
Previously you needed to pay for a $10 per month or more for a Spotify subscription if you wanted to listen on any of those devices.
Meanwhile in related-possibly-only-in-my-mind news, streaming live TV platform Sling TV has announced that it’s now available on two additional devices:
- Google Nest Hub smart display
- Google Nest Hub Max smart display
Interestingly, Sling TV also supports Facebook’s Portal smart displays, but it does not work with the Amazon Echo Show line of devices or other Google Assistant-powered screens such as the Lenovo Smart Display line of devices.
But the services does support a pretty broad range of other platforms including Apple TV, Roku, Amazon Fire TV, Android TV, Chromecast, Samsung and LG smart TVs, and Oculus headsets as well as phones, computers, and game consoles.

Matthew McConaughey Reveals He Almost Died From Venomous Snakebite
by Brent FurdykMatthew McConaughey is opening up about a terrifying experience he had with a venomous snake while vacationing Down Under.
Chatting with Australia’s “Today” while promoting Wild Turkey bourbon and his new eco-tourism enterprise, the “Dallas Buyers Club” Oscar winner recalled a visit to Australia back in the 1980s when he encountered a venomous brown snake, one of the most lethal snakes in the world.
During his chat with the show, McConaughey recalled almost stepping on a deadly brown snake. “I should have been bitten,” he said.
“It was a bit dark,” he added. “It went right through my legs and gave me bit of a scare.”
Luckily for McConaughey, a snake-savvy pal was on hand.
“My friend came over and they caught it and said, ‘That’s a brown snake, mate… that could have really sucked.'”
As he declared: “That’s [why it’s] my favourite animal, because it didn’t bite me!”

If plot_centerline == True, plot a line from the centroid to the top center of each subfault to show what direction is up-dip.
If slip_color == True then use the color map cmap_slip (which defaults to matplotlib.cm.jet) to color the subplots based on the magnitude of slip, scaled between cmin_slip and cmax_slip. (If these are None then scaled automatically based on range of slip.) If slip_time == None then colors are based on the final slip. For dynamic faults, slip_time can be set to a time and the dynamic timing of each subfault will be used to compute and plot the slip at this time.
If plot_rake == True, plot a line from the centroid pointing in the direction of the rake (the direction in which the top block is moving relative to the lower block. The distance it moves is given by the slip.)

Calculate moment magnitude based on seismic moment Mo. Follows USGS recommended definition from
The SubFault and Fault classes each have a function Mo to compute the seismic moment for a single subfault or collection respectively.
- class clawpack.geoclaw.dtopotools.SiftFault(sift_slip=None)¶
Define a fault by specifying the slip on a subset of the SIFT unit sources. The database is read in by load_sift_unit_sources. See http://www.pmel.noaa.gov/pubs/PDF/gica2937/gica2937.pdf for a discussion of these unit sources, although the database used is more recent than what is reported in that paper and uses different notation for the subfault names. The subfault database used was downloaded from
Example:
>>> sift_slip = {'acsza1':2, 'acszb1':3} >>> fault = SiftFault(sift_slip)
results in a fault with two specified subfaults with slip of 2 and 3 meters.
- set_subfaults(sift_slip)¶
- sift_slip (dict) is a dictionary with key = name of unit source
- and value = magnitude of slip to assign (in meters).
- class clawpack.geoclaw.dtopotools.SubFault¶
Basic sub-fault specification.
- Mo()¶
Calculate the seismic moment for a single subfault
Returns in units of N-m and assumes mu is in Pascals.
- convert2meters(parameters)¶
Convert relevant lengths to correct units.
Returns converted (length, width, depth, slip) Deprecated?
- convert_to_standard_units(input_units, verbose=False)¶
Convert parameters from the units used for input into the standard units used in this module.
- coordinate_specification = None¶
Specifies where the latitude, longitude and depth are measured from.
- depth = None¶
Depth of subfault based on coordinate_specification.
- dip = None¶
Subfault’s angle of dip
- dynamic_slip(t)¶
For a dynamic fault, compute the slip at time t. Assumes the following attributes are set:
- rupture_time
- rise_time
- rise_time_ending: optional, defaults to rise_time
- geometry¶
Subfault geometry
- latitude = None¶
Latitutde of the subfault based on coordinate_specification.
- length = None¶
Length of subfault in standard units.
- longitude = None¶
Longitude of the subfault based on coordinate_specification.
- okada(x, y)¶
Apply Okada to this subfault and return a DTopography object.
Input: - x,y are 1d arrays
Output: - DTopography object with dz_list = [dz] being a list with
single static displacement and times = [0.].
Currently only calculates the vertical displacement.
Okada model is a mapping from several fault parameters to a surface deformation. See Okada 1985, or Okada 1992, Bull. Seism. Soc. Am.
okadamap function riginally written in Python by Dave George for Clawpack 4.6 okada.py routine, with some routines adapted from fortran routines written by Xiaoming Wang.
Rewritten and made more flexible by Randy LeVeque
Note: self.coordinate_specification (str) specifies the location on each subfault that corresponds to the (longitude,latitude) and depth subfault.
See the documentation for SubFault.set_geometry for dicussion of the possible values self.coordinate_specification can take.
- rake = None¶
Rake of subfault movement in degrees.
- set_geometry()¶
Set self._geometry, a dictionary containing bottom, top, centroid, and corner values of x,y, and depth at top and bottom of fault, based on subfault parameters. Automatically called first time user requests self.geometry.
Note: self.coordinate_specification specifies the location on each subfault that corresponds to the (longitude,latitude) and depth of the subfault. Currently must be one of these strings:
“bottom center”: (longitude,latitude) and depth at bottom center
“top center”: (longitude,latitude) and depth at top center
“centroid”: (longitude,latitude) and depth at centroid of plane
- “noaa sift”: (longitude,latitude) at bottom center, depth at top,
This mixed convention is used by the NOAA SIFT database and “unit sources”, see: http://nctr.pmel.noaa.gov/propagation-database.html
The Okada model is expressed assuming (longitude,latitude) and depth are at the bottom center of the fault plane, so values must be shifted or other specifications.
- slip = None¶
Slip on subfault in strike direction in standard units.
- strike = None¶
Strike direction of subfault in degrees.
- width = None¶
Width of subfault in standard units.
- class clawpack.geoclaw.dtopotools.SubdividedPlaneFault(fault_plane, nstrike=1, ndip=1, slip_function=None, Mo=None)¶
Define a fault by starting with a single fault plane (specified as fault_plane of class SubFault) and subdividing the fault plane into a rectangular array of nstrike by ndip equally sized subfaults.
By default,the slip on each subfault will be initialized to fault_plane.slip so that the slip is uniform over the original plane and the seismic moment is independent of the number of subdivisions.
Alternatively, the slip distribution can be specified by providing a function slip_distribution, which should be a function of (xi,eta) with each variable ranging from 0 to 1. xi varies from 0 at the top of the fault to 1 at the bottom in the down-dip direction. eta varies from one edge of the fault to the other moving in the strike direction. This function will be evaluated at the centroid of each subfault to set the slip.
Can also specify a desired seismic moment Mo in which case the slips will be rescaled at the end so the total seismic moment is Mo. In this case the slip_distribution function only indicates the relative slip between subfaults.
- class clawpack.geoclaw.dtopotools.TensorProductFault(fault_plane, slip_along_strike=None, slip_down_dip=None, nstrike=1, ndip=1, Mo=None)¶
Define a fault by starting with a single fault plane (specified as fault_plane of class SubFault) and subdividing the fault plane into a rectangular array of nstrike by ndip equally sized subfaults.
Then define the slip on each subfault via two one-dimensional functions slip_along_strike and slip_down_dip that specify the slip as a function of fractional distance in the along-strike and down-dip direction respectively (i.e. the argument of each goes from 0 to 1).
Setting either to None defaults to constant function 1.
The slip is set by evaluating the tensor product at the centroid of each subfault.
Can specify a desired seismic moment Mo in which case the slips will be rescaled at the end.
- class clawpack.geoclaw.dtopotools.UCSBFault¶
Fault subclass for reading in subfault format models from UCSB
Read in subfault format models produced by Chen Ji’s group at UCSB, downloadable from:
- read(path, rupture_type='static')¶
Read in subfault specification at path.
Creates a list of subfaults from the subfault specification file at path.
Subfault format contains info for dynamic rupture, so can specify rupture_type = ‘static’ or ‘dynamic’
- clawpack.geoclaw.dtopotools.convert_units(value, io_units, direction=1, verbose=False)¶
convert value to standard units from io_units or vice versa. io_units (str) refers to the units used in the subfault file read or to be written. The standard units are those used internally in this module. See the comments below for the standard units. If direction==1, value is in io_units and convert to standard. If direction==2, value is in standard units and convert to io_units.
- clawpack.geoclaw.dtopotools.plot_dz_colors(x, y, dz, axes=None, cmax_dz=None, dz_interval=None, add_colorbar=True, verbose=False, fig_kwargs={})¶
Plot sea floor deformation dz as colormap with contours
- clawpack.geoclaw.dtopotools.plot_dz_contours(x, y, dz, axes=None, dz_interval=0.5, verbose=False, fig_kwargs={})¶
For plotting seafloor deformation dz
- clawpack.geoclaw.dtopotools.rise_fraction(t, t0, t_rise, t_rise_ending=None)¶
A continuously differentiable piecewise quadratic function of t that is
- 0 for t <= t0,
- 1 for t >= t0 + t_rise + t_rise_ending
with maximum slope at t0 + t_rise. For specifying dynamic fault ruptures: Subfault files often contain these parameters for each subfault for an earthquake event.
t can be a scalar or a numpy array of times and the returned result will have the same type. A list or tuple of times returns a numpy array.
- clawpack.geoclaw.dtopotools.strike_direction(x1, y1, x2, y2)¶
Calculate strike direction between two points. Actually calculates “initial bearing” from (x1,y1) in direction towards (x2,y2), following http://www.movable-type.co.uk/scripts/latlong.html


Info
The alert elements is a nicer looking version of the alert message box. Its used to display a simple message to the user. It does not have many theme options yet.
To toggle an alert you have 2 different options. 1 you can set the toggle property to a variable, then change that variable, 1 is on 0 if off.
The second option is to use the on-event and off-even attributes. Set either of them to a string that is the EventBroker event you want to trigger the alert. (see Brokers)

Overview
Even in today's world where we are surrounded by sophisticated technologies and modern gadgets,there is nothing which can replace the magic of literature. It is this literature which encompasses the thoughts of geniuses since time immemorial,it is this literature which has influenced millions of tourch beares through ages,it is this literature which has swayed emotions of the people-ranging from common folk to the mighty personalities.The art of writing and expressing feelings using emotions dates back to the era from where the evolution of a cultured and civilized society began...and is continued till date and undoubtedly will be progressing in the future in a more paceful manner.The literatur has created personalities and shacked mighty empires for it seems the most powerful tool for freedom even more effectives than the bloodshed warfare,so the saying goes A pen is mightier than a sword is absolutely true and history here testimonifies this fact.
HINDI
Our mother tongue hindi has it's own interesting literature and the past associated with it.India has always been a land of wisdom and this land has provided many geniuses to the world.Hindi literature helps me to capture all their ideas.To name a few of my all time favorites-Munshi Premchand whose stories helps me to get a glimpse of our typical indian society and the problems associated with it,poems of Ramdhari Singh Dinkar and Sohanlal Diwedi which make me feel interesting,dohas of Kabirdas and Raidas which engulf me with their wisdom and finally the Madhushala by Harivansh Rai Bachann which is indeed with reading.>


Intel's 6-year-old Haswell Pentium processor is making a comeback - but why now?
by Darren AllanIntel's 6-year-old Haswell Pentium processor is making a comeback - but why now?
Presumably due to stock shortages

Fed up of rebooted movies? Or remakes of old games?  Well we’re not sure how you’ll feel about the prospect of ancient processors rising from the silicon grave, but this is exactly what Intel has done with its latest move in the CPU arena.
Intel’s Pentium G3420 is a Haswell chip based on a 22nm process which was released back in Q3 of 2013, over six years ago now, but as Tom’s Hardware spotted, it has been resurrected and is now back on the chip giant’s roadmap.
- Intel turns to Samsung for help keeping up with AMD?
- Intel CPUs aren't safe unless you disable hyper-threading?
- Check out how to overclock your CPU
In a product change notification document, Intel let customers know that: “Cancelling this Product Discontinuance completely per new roadmap decision and enabling the product long term once again.”
The dual-core Pentium processor, which has a base clock speed of 3.2GHz, will apparently be sold through to May 2020.
What is dead may never die
So what’s this all about then? Surely no one wants to buy an old and crusty Pentium which was first released six years ago?
Well, no, not in the consumer sphere anyway, but this chip is aimed at PC manufacturers (for use in cheap builds) and the likes of the embedded market and thin clients.
The reason it could have been brought back, as Tom’s Hardware theorizes, is perhaps to help cope with demand in such markets, given that Intel is struggling to make enough contemporary CPUs (and thus might need to fall back to an older process, to help pick up some of the slack).
We recently heard Intel apologize for these processor shortages, which have been ongoing for some time now, and are set to remain a problem.
Investing ‘record’ levels of capital to boost 14nm production throughout the course of 2019 simply hasn’t been enough, and we have previously heard that Intel has shifted to use 22nm on CPUs which are on the fringe to help deal with demand – and arguably that might be the case here.
