Introduction
Last year, I wrote an article describing the free and open-source graphics stack, explaining all of the interconnected pieces: X11, graphics drivers, DRM, and DRI, and their roles in getting pixels placed on the screen. In the year since, I've answered a lot of really good questions from the Linux community about my post, about X11, and about Wayland. I've learned a lot. Several new technologies have appeared, and I have started to take a more active role in this myself, as part of our efforts to port GNOME to Wayland.
However, I still field plenty of questions from lots of people about this, and a lot of the time, it's extremely simple stuff: "What is X?" "How does it interact with my graphics card and mouse/keyboard?" "What do apps use X for?" "What is Wayland, and how does it fit into the picture?" "What problems did X have that made us want to write new display server technologies?"
These sort of questions were what inspired me to write "The Linux Graphics Stack" in the first place, but there's really never been a comprehensive, historical writeup of our display server technologies in general. So, I chose to spend my free time at Red Hat writing it.
Now, compared to some of my colleagues, I'm relatively new to the Linux development scene, with only five or so years of experience. I've also arrived late, way after we've added lots of hacks to keep the X Window System fresh. Most of my knowledge comes from talking to my more experienced coworkers in person, digging through mailing list and newsgroup archives, and IRC discussions with the great sports in #xorg-devel. So, there's a good possibility that I'll get something wrong, guy-who-worked-at-DEC-in-the-80s-waiting-to-correct-me! I'm genuinely sorry if I misrepresent something. If you want to discuss this at all, shoot me an email at<EMAIL_ADDRESS>and let's try to work something out!
I also really don't want to inject my bias into this too much. While I do personally believe Wayland is going to become The Linux Display Server Of The Future®, and that is a good thing, I'm not trying to rip X apart! My intention here is twofold: I want to explain a lot of the more undocumented or harder-to-grasp features built into X11 (the permutations of input grabs, for instance), and I also want to provide an accurate, historical context on why a certain feature was added (COMPOSITE, for instance), and all the clever hacks we've invented along the way (WM_TAKE_FOCUS, for instance). I really want this to be a resource for somebody looking to learn. If I've inspired anybody out there to write any code, I've accomplished my goal.
But before we begin...
Since this article contains a lot of interactive demos relying on fairly modern browser technology, let's make sure that everything is OK before continuing. I've been testing this on modern versions of Firefox Nightly and Chrome Canary.
If you can see the stipple pattern above, that means that your browser is modern enough to see the interactive demos.
You might have noticed that when you ran your mouse over the stipple, your cursor changed. That's because this isn't just any old stipple image, that stipple is actually the background of a full X server session running in your browser using HTML5 canvas. All of the interactive demos will use this framework to explain what's going on under the hood.
Basic Architecture
Although it may sound a bit stilted, notice how I keep saying "the X Window System" instead of the more traditional shorthands "X", "X11", or "Xorg"? I want to be very careful to separate the ideas and design of the system from its component parts.
The X Window System is a networked display system. A server component, the X server, is responsible for coordinating between all of the clients connected, taking input from the mouse and keyboard, and pushing pixels on the output. The most popular X server implementation is the Xorg X server, developed by the X.Org Foundation and community. There are other X server implementations: you might remember that Xorg was forked from XFree86 a decade ago, that Sun Microsystems has had several X server implementations, in both Xsun and XNeWS. Today, Xorg is the dominant X server implementation, getting most of the development. But back in the day, multiple competing implementations existed.
X servers and X clients all talk a standardized network protocol to each other, known as X11. This protocol is well-specified, from the wire format to the semantics of every request. The protocol documentation linked above is invaluable documentation for any hacker who wants to learn more about this stuff.
Applications and toolkits don't write the wire format onto the socket directly, however. They often use client libraries that implement the protocols, like the traditional Xlib library, or the somewhat newer xcb.
I'm going to try and be precise in my nomenclature in this article.
When I talk about features or design decisions of the overall system, I will try to call it
the X Window System, even if it sounds a bit verbose. e.g.
The X Window System provides us Pixmaps, which are images in the
server's memory.
When I talk about features or details of the network protocol, I will talk about
the X11 protocol. e.g. The X11 protocol
provides for a generic extension mechanism, which allows for a forward-compatible way to implement new
features without having to redesign older parts of X11
.
When I talk about the behavior of a client or a server, I'll say X client
or X server e.g. Using the MIT-SHM extension, X
clients can pass memory buffers to the X server using POSIX shared
memory, which prevents networking and large copies
.
When I talk about features or the architecture in the Xorg X server implementation, I'll mention it
explicitly as Xorg or the Xorg X server,
e.g. In order to make drawing calls accelerated, Xorg video drivers can
provide hardware-accelerated versions of certain drawing primitives through EXA.
If I ever say "such-and-such is a feature of X", it's a bug.

The source code to this article and all demos is freely available under the MIT/X11 license on GitHub for inspection. I've tried to make the source code well-commented, and be a useful resource for learning from as well, so for a third dimension of learning, you can inspect my source code for the server and all the demos and figure out how things work that way.
Some of the more tricky code in there has been ported from the Xorg X server itself along with its helper library, pixman.
Some of the images in this article have been adapted from other images on the web. The two kitten images in the Expose event demo were adapted from photos taken by quatre mains and fazen, shared under a CC-BY-2.0 license. Thanks to [placekitten] for finding these images for me.

Special thanks to Keith Packard, Alan Coopersmith, Adam Jackson, Peter Hutterer, and Owen Taylor for digging into the source code, protocols, mailing lists and other archives to help me figure out some of the more odd and hairier X11 semantics when I was working on this. Sorry for driving you guys crazy with this project.

To get the current split data, index the Splits property of the current Slice with the Equity Symbol. Slice objects deliver unique events to your algorithm as they happen, but the Slice may not contain data for your security at every time step. To avoid issues, check if the Slice contains the data you want before you index it.
def OnData(self, slice: Slice) -> None: if slice.Splits.ContainsKey(self.symbol): split = slice.Splits[self.symbol] split_type = {0: "Warning", 1: "SplitOccurred"}.get(split.Type) self.Log(f"Split: {split.Symbol}\t{split.SplitFactor}\t{split.ReferencePrice}\t{split_type}")

LHC decision on Nawaz validates PTI government's stance: PM's aide
by Our CorrespondentISLAMABAD: Special Assistant to the Prime Minister on Accountability Mirza Shahzad Akbar on Sunday said the Lahore High Court’s (LHC) verdict on the removal of former prime minister Nawaz Sharif’s name from the Exit Control List (ECL) “reinforces the federal government’s stance”.
Addressing a press conference along with Attorney General Anwar Mansoor Khan in Islamabad, Akbar stressed that there was no legal ground to remove a convict’s name from the ECL.
“Nawaz Sharif was granted permission on humanitarian grounds since his condition is serious and he needs medical treatment abroad,” he said.
The PM’s aide asserted that the LHC has reinforced the federal cabinet’s decision of giving Nawaz one-time permission to travel abroad.
“The permission is for four weeks,” he said, adding that Pakistan Muslim League – Nawaz (PML-N) President Shehbaz Sharif has vowed to ensure his brother’s return.
“The Sharif family has a history of not honouring their agreements. Even the Supreme Court of Pakistan has said that Nawaz Sharif is neither sadiq nor amin.”
Shehbaz Sharif would be liable for prosecution if he violates the undertaking, he added.
Attorney General Khan said the government still has the option of challenging the LHC decision but that call would be made by the federal cabinet.
He said the court accepted two of the three stipulations proposed by the cabinet and has given the former prime minister four weeks to seek treatment.
Khan asserted that the period had already started and Nawaz would have to approach the court for an extension since he was legally bound to return to Pakistan.
Earlier on Sunday, the PML-N confirmed that Nawaz would be flying to London on Tuesday.
PML-N leader Marriyum Aurangzeb released a statement saying that an air ambulance will arrive on Tuesday morning to transport Nawaz to London for medical treatment.
She said doctors conducted a detailed examination of the three-time former prime minister and cleared him for travel after consultation among themselves.
“A high dose of steroids continues to bring his platelet count to a suitable level for travel. He is also receiving medication for blood sugar and other medical issues. The doctors are following a rigorous strategy to ensure he is able to travel safely,” said Marriyum.


Figure 1: The Display menu
The Display menu contains a list of checkboxes that allow the user to plot the results of any analysis. If a checkbox is selected, the appropriate graph will be displayed once it becomes available. De-selecting a checkbox will close the graph if it is already displayed. Closing the graph windows will cause the corresponding checkboxes to be de-selected. Certain graphs are only calculated when analysing more than one frame of data, and others are only calculated at the user's request. For example, a volume fraction profile (checkbox "Hilbert" cannot be displayed if correlation function analysis has been performed).
Always calculated:
| Data | The original scattering data | (see File) |
| Extrapolation | The extrapolated data | (see Extrapolation) |
Calculated when analysing more than one frame of data:
| Guinier radius | Guinier radius of gyration v. frame | (see Extrapolation) |
| Thermal background | Bonart thermal backround v. frame | (see Extrapolation) |
| Porod constant | Porod constant v. frame | (see Extrapolation) |
| Sigma | Sigma v. frame | (see Extrapolation) |
| Second moment | Second moment of the data v. frame | (see Transform) |
Calculated at request of user:
| Gamma1 | The 1-D correlation function | (see Transform) |
| Hilbert | The Volume Fraction Profile | (see Transform) |
| Re-transform | The Fourier transform of the 1-D correlation function | (see Transform) |
| Interface distribution | The Interface Distribution Function | (see Transform) |
The extrapolated data and re-transform are superimposed on the original
scattering data when displayed. All other graphs are displayed in separate windows.
The use of CORFUNC graphics windows is explained in Section
6: Graphics Windows.

Drawdown is the largest peak to trough decline in your algorithm's equity curve. Drawdown is calculated as
$$ 1- \frac{v^{t\ge s}_{min}}{v^s_{max}} $$where $v^s_{max}$ is the maximum equity value up to time $s$ and $v^{t\ge s}_{min}$ is the minimum equity value at time $t$ where $t\ge s$. The following image illustrates how the max drawdown is calculated:
During the first highlighted period in the preceding image, the equity curve dropped from 106,027 to 93,949 (11.4%). During the second highlighted period, the equity curve dropped from 112,848 to 99,576 (11.8%). Since 11.8% > 11.4%, the max drawdown of the equity curve is 11.8%.
The benefit of using drawdown as the objective is that it's psychologically easier to keep an algorithm deployed in live mode if the algorithm doesn't experience large drawdowns. The drawback of using drawdown is that it may limit the potential returns of your algorithm.

We’ve been here for four years. We have ventured to Union Street Diner on multiple occasions, trekked up Bong Hill on the last night of the year just to see the view from the top and sat through countless lectures. By now, we know Athens, so take it from us: enjoy yourself while you’re here.
Chuck Greenlee, Opinion Editor
Actually do your homework before you go out. You won’t wake up before class to do it the next day. I promise.
 Even if you’re in a tiny dorm room, keep it tidy, invest in some cleaning supplies, and for the love of all that is good and holy, make your bed! Your future self and inner Monica Geller will thank you.
A decorated cap thanking "Mom and Dad" is seen during commencement in The Convo at OU's 2017 graduation. (FILE)
Alex McCann, Digital Managing Editor:
Look, we all know you’re probably going to drink at least a little bit. That’s fine. Just be smart about it. (Do I sound like a dad? Oh boy.) If you’re drinking in the dorms, don’t be loud or you’ll get caught by your RA — I’m speaking from personal experience here. If you’re at a party, stick with your friends and keep an eye on each other. If you’re at the bars, act like an adult and pretend you’ve been there before.
 Introduce yourself to strangers. Talk about majors and hometowns and music and sports and whatever else you like. Meet the people who live at the house where you’re partying. At least you can thank them for hosting a party or compliment them on their artful decor skills (read: a Pulp Fiction poster, an old couch and a table for beer pong).
Speaking of which, play a game or two of beer pong (just watch your elbows). Don’t be nervous. Smile. You’re in the happiest place on Earth now. Enjoy it — it goes way, way too fast.
Oh, and call your parents once in a while. They miss you.
Georgia Davis, Blogs Editor:
OU is a wonderful place to find yourself.  I know. It’s cheesy. I didn’t expect to find a place I love more than my cozy home with my family. But I found it at OU, and more specifically, at The Athena Cinema. Smile at strangers as you walk by them on the street. Go to a football game and leave at halftime like everyone else. And enjoy eating in the dining halls because meal prep is difficult. Make OU your own, and respect its history.
Maddie Capron, Managing Editor:
Take time to fall in love with Athens. Go to Union Street Diner at 4 a.m. just because you can. Walk around campus in different ways every now and then. Scream as loud as you can for the Marching 110 Alumni Band when they make their way down Court Street during Homecoming. Watch all of the people from the Courthouse steps on Halloween. Visit Pumpkin the Board of Elections cat during bad days. Make many different friends and take time to lie in your dorm room and watch movies and eat junk food on rainy days. College is fun. Fall in love with it.

nlist is an R package to create and manipulate numeric list (nlist) objects.
An nlist is an S3 class list of uniquely named numeric atomic (natomic) objects. An natomic object is an integer or double vector, matrix or array. nlist objects are the raw data inputs for analytic engines such as JAGS, STAN and TMB.
An nlists object is a S3 class list of nlist objects with the same names, dimensionalities and typeofs. nlists objects are useful for storing multiple realizations of simulated data sets. They can be converted to coda::mcmc
and coda::mcmc.list
objects.

Get and install Contenticious
Installing Contenticious is easy since it's a CPAN module. Just use your standard procedure to install it, which would be something like
$ cpan Contenticious
That would download Contenticious and its dependencies, run tests and finally install it.
Done.
Development versions
To use the latest development version, you need to clone the source repository:
$ git clone git://github.com/memowe/contenticious.git
With cpanminus you can install all needed dependencies and Contenticious itself from here:
$ cd contenticious
$ cpanm --sudo .
Done.
The traditional way is also possible since Contenticious ships with
a Makefile.PL
:
$ cd contenticious
$ perl Makefile.PL
$ make
$ make test
$ sudo make install
Done.
Next step: Prepare your first Contenticious site

The goal of altair is to help you build Vega-Lite visualizations. Using the reticulate package, it provides an interface to the Altair Python package. This approach is distinct from efforts to build a native R interface to Vega-Lite, by Bob Rudis and coworkers: the vegalite package, which has inspired this effort.
In this documentation, the capitalized word Altair shall refer to the Python package; the lower-case word altair shall refer to this R package.
A development version is available from GitHub:
Because you are using a Python package, you may have some additional installation steps. These steps are described in greater detail in the Installation article.
Python must be installed on your system. I recommend using a Conda installation; Miniconda works well and installs more-quickly than Anaconda.
If you work in a corporate or institutional environment, you may have to specify the location of your SSL certificate, or deal with a proxy. The installation article has a section on this.
Create a Conda environment called "r-reticulate"
. The reticulate folks recommend standardizing on a common name for all packages that use reticulate. For more information, there is a section in the installation article.
Install Altair into your "r-reticulate"
environment using altair::install_altair()
.
You may wish to add a line like this to the .First()
function in your .Rprofile
:
The use_condaenv()
function is called to provide a hint to reticulate on which Python environment to use.
library("altair")
vega_data <- import_vega_data()
chart <-
alt$Chart(vega_data$cars())$
mark_point()$
encode(
x = "Horsepower:Q",
y = "Miles_per_Gallon:Q",
color = "Origin:N"
)
chart
Some things to keep in mind:
Where you see a .
in the Python examples, use a $
instead.
In your data, columns that contain dots can be wrapped in square brackets in Altair specifications, e.g. [Sepal.Width]
, to keep Altair from throwing an error.
These and other “gotchas” are compiled, along with workarounds, in an article: Field Guide to Python Issues.
The documentation for this package includes some articles:
Installation: some more-detailed instructions
Manifesto: an outline of some high-level development ideas, which may change from time to time
Gallery:
Examples:
First Example: a walkthrough to get a first chart to work
Tooltips: shows how Vega-Lite implements tooltips as an encoding within a chart, with formatting options
Vega Datasets: work with Vega datasets using import_vega_data()
View Composition: how to facet, add layers to, repeat, and concatenate charts
Interactive Examples: a set of examples that work towards linked-brushing of two scatterplots
Field Guides:
Field Guide to Python Issues: A place for “gotchas” and their workarounds
Field Guide to Rendering Charts: How to use the vegawidget()
function to render charts as HTML
This package rests on these foundations:
Altair: Python interface to Vega-Lite
reticulate: R framework to work with Python
Vega-Lite: a grammar of interactive graphics
htmlwidgets: R framework to work with JavaScript visualizations
As well, a particular debt is owed to the folks behind the vegalite package, as it provided a lot of the inspiration for these efforts.
This project is a collaborative effort. In addition to the principal author:
Alicia Schep has contributed the concatenation functions, as well as sorted out many of the Python, JavaScript, and package-API issues.
Haley Jeppson has adapted the Altair Example Gallery to R.
Heike Hofmann has been an invaluable advisor, providing incisive feedback, and insight into the fundamentals of interactive graphics.

gretty {
// ...
serverConfigFile = 'someFile.xml'
// ...
}
"tomcat.xml" is the configuration file for Tomcat (for server itself, not for web-app).
The purpose and syntax of "tomcat.xml" is documented in Tomcat configuration reference.
Gretty recognizes and supports "tomcat.xml". As soon as Gretty finds existing "tomcat.xml" file, it reads the file and uses it to configure tomcat server. Even if "tomcat.xml" is not found, Gretty still works.
You can (but you don’t have to) specify "tomcat.xml" file via property "serverConfigFile" in Gretty configuration:
gretty {
// ...
serverConfigFile = 'someFile.xml'
// ...
}
If serverConfigFile is not specified, Gretty looks for one of the files: "tomcat8.xml" (for Tomcat 8), "tomcat7.xml" (for Tomcat 7), "tomcat.xml", "tomcat8-server.xml" (for Tomcat 8), "tomcat7-server.xml" (for Tomcat 7), "server.xml". Tomcat version is defined by gretty.servletContainer property.
If explicitly defined serverConfigFile represents an absolute path, gretty will use just that.
If implicitly or explicitly defined serverConfigFile represents a relative path, gretty tries to resolve it in the following directories:
"$project.projectDir/tomcat"
"$project.projectDir/server"
"$project.projectDir/config"
recursively in the abovementioned folders of the overlay sources (if any)
When you generate a product, "tomcat.xml" file is automatically copied to "conf" subdirectory and referenced in "conf/server.json". The running product automatically applies "tomcat.xml" files listed in "conf/server.json".
When you run a farm or generate product from a farm, serverConfigFile is taken from farm or product configuration, not from gretty configurations.
Gretty sources contain example program demonstrating support of "tomcat.xml" at work:

Opioid exposure before birth affects infant brain
by HealthDay NewsExposure to opioids in the womb may affect an area of the newborn brain that regulates emotions, a new study shows.
Researchers used MRIs to assess brain activity in 16 full-term infants while they slept, specifically focusing on connectivity in a region called the amygdala, which is responsible for emotions such as anger, fear, sadness and aggression.
Eight of the infants were exposed to opioids in the womb, according to the study being presented Monday at the annual meeting of the Radiological Society of North America (RSNA), in Chicago.
"Our early results show significant differences in the way the amygdala connects to different brain regions between the infants exposed to opioids and the opioid-naive infants," said researcher Dr. Rupa Radhakrishnan. She's an assistant professor of radiology and imaging sciences at Indiana University School of Medicine.
"We still need to study what the clinical implication of this finding may be," Radhakrishnan said in a meeting news release.
Opioid use in pregnancy can pose serious risks to maternal, fetal and infant health, and it has become a major public health crisis.
Babies who've been exposed to opioids in the womb suffer from drug withdrawal, or a group of conditions known as neonatal abstinence syndrome, after birth, and it's thought that exposure to opioids in the womb may cause lasting harm to brain development and behavior.
"Little is known about brain changes and their relationship to long-term neurological outcomes in infants who are exposed to opioids in utero," Radhakrishnan said.
"Many studies have looked at the impact of long-term opioid use on the adult and adolescent brain, but it is not clear whether social and environmental factors may have influenced those outcomes," she explained. "By studying infants' brain activity soon after birth, we are in a better position to understand the effect of opioids on the developing brain."
Research presented at meeting is considered preliminary until published in a peer-reviewed journal.
More information
The U.S. Centers for Disease Control and Prevention has more on opioid use during pregnancy.

static
variables that are lazily initialized in a non-thread-safe manner.
Lazy initialization of static
variables should be done with an appropriate synchronization construct
to prevent different threads from performing conflicting initialization.
When applicable, a quick-fix, which introduces the lazy initialization holder class idiom, is suggested. This idiom makes use of the fact that the JVM guarantees that a class will not be initialized until it is used.
Example:
class X {
private static List<String> list;
public List<String> getList() {
if (list == null) {
list = List.of("one", "two", "tree");
}
return list;
}
}
After the quick-fix is applied:
class X {
private static final class ListHolder {
static final List<String> list = List.of("one", "two", "tree");
}
public List<String> getList() {
return ListHolder.list;
}
}


Brief background - I've been having Reikee/energy work combined with Acupuncture work over the past few weeks to help with psychic, spiritual and body healing. I have never had a bad experience with nitrous/gas in the past but did have an emotionally bad 'trip' with mushrooms a number of years, about 13, ago.
I felt it was time to replace the old metal fillings with current because I knew, and it was confirmed, that the metal was leaking out and into my system. Before the dentist started I explained to the dentist that I didn't want novacane because of my hypersensative to needle/pain and honestly require at least 3x normal dose for painkillers to work, whereas in the past nitrous had worked and nonpainful.
Within about 5 or 6 minutes I had the sensation of being 'stuck' in my body, but no feelings at all through out my entire body. I could see everything with crisp clarity but no physical feeling at all. I told the dental assistant to write something down I know she must have thought quite odd/strange/weird... and to this day I believe it to be true and quite scarry.
'Nitrous oxide has the ability in some people to separate the spirit from the body.'
She immediately started humming or whistling or something and on the side I asked her if the gas has ever had an affect on peoples sense of time. She must not have known because she said no but after everything was done the dentist said yes.
This was only the tip of the Day Mare...
When the dentist started drilling everything was going ok and I could actually tell each one by gently raising my arm up which implement was causing discomfort or pain, etc. The assistant was on my left and when she pressed a little too hard with suction tube I raised my left hand/arm and when the drilling struck a nerve I could raise my right hand/arm to let him know. I felt happy about it because the drilling started after I felt as if I had total body numbness.
However, shortly after he started drilling they must've given me too much nitrous because when I was in the chair all sense of time, space, and dimension went totally out in which what I saw and truly experienced was a rift in reality and time with a full split down the center. This was followed by my Day Mare in which my entire life's existance was downloaded into a computer chip, without my knowledge or consent, and stuck in an endless loop - and I was fully conscious when the full download and timeloop occured.
My reaction in reality from what the dentist told me was to go into total terror hysterics and during this time chomped down on his finger/s while he was working on my teeth. To say the least this was quite dangerous not just for the dentist but me as well since they had not strapped me down and held my mouth open with some type of frame to keep it open... while he had the drill in hand (yikes). Not to mention the affect my hysterics must have had on the other people in the dentist office while others were either waiting or having work done by the other one or two dentists etc. Certainly I felt bad about how this must have affected the other people in the office - but at the same time I had a very scarry revelantion...
If the government truly has determined that nitrous can separate people's spirit or separate them from their physical body, combined with real hypnosis, and voodon or dark magicks - the stories of alian abduction and torture could be the combination of hypnosis, mind/body, spirit/body control... and another form of true torture would be to hypnotise a person after separating their spirit from their body to relive a force self induced DayMare for what would seem indefinitely.
There is also the factor in which company/ies and government are working together to encourage everyone to have a chip embeded in them, starting with children then pets - then all people. With current bluetooth capabilities and cell phones and laptops, it would not surprise me if a person was implanted with a chip connected to their nervous system that there would be the ability to without a person's knowledge or consent to 'download' their entire life experiences and consciousness into another computer over time if not in current day using secret technologies.
Then there are the sci-fi stories, some of which with pending technology breakthroughs with time - that there could be a Real time anomoly or 'time loop' if not by intention then by accident.
Considering the Real abilities and research of the US and other governments and their current practices along Dark Paths - it would not surprise me although it certainly is a terrifying concept.

Philippines, Malaysia Traders Are Buying the Bitcoin Dip
by Christina CombenThey say the best time to buy is when there’s blood on the streets. What’s harder to assess is just how much more haemorrhaging there is to come. Some Asian traders are pretty confident bitcoin has seen a new low though. According to Coindance, Bitcoin P2P trading in the Philippines and Malaysia is taking off.
Asian Bitcoin Traders Show Heightened Interest
Trading on peer-to-peer site Paxful saw a monumental leap this week in bitcoin trading volume in the Philippines, despite the leading asset tanking to a new 6-month low. The number of bitcoins passing hands springboarded from 291,837 Philippine pesos last week to a massive 1,221,000 this week.
Not only is that a whopping five times more than the previous week, but it also represents an all-time high for BTC trading on Paxful in this country.
Malaysia is also registering a significantly higher trading volume over the past week than the previous. Bitcoins exchanged at a value of 149,724 Malaysian ringgit (RM) compared to 157,615 RM on November 23. Bitcoin hodlers are accumulating here, representing another ATH high for Paxful in Malaysia.
Many BTC traders may have lost faith in the market, but apparently the Philippines and Malaysia are buying the dip right now. Both countries show huge spikes in Paxful BTC trading volume since the Bitcoin price crash.
China, Europe, Japan All Break Rising Uptrends
Conversely, Europe, China, and Japan have all broken away from their rising P2P trading uptrends. Analysis from the same source shows that in these three major regions, BTC demand has plummeted.
Japan has seen a near 30% drop in demand as BTC traded plunged from 12,106,232 in Japanese yen to 9,729,708.
China also saw a downtrend from some 14,604,047 in Chinese yuan to 12,624,014 from the previous week to the most recent figures.
At the same time, Europe told a similar story with another significant drop in demand from 1,230,770 euros to 1,040,874 euros of BTC traded.
Amid continued pressures driving down BTC price from BitMEX dumping to Chinese anti-cryptocurrency rhetoric, some traders appear confident that the bottom is in.
While China, Europe, and Japan remain unconvinced, early movers in Asia are taking full advantage of Bitcoin’s reduced price. Is this a sign that the bottom is really in, or can we expect further decline over the rest of this year? Only time will tell.
Do you think Bitcoin price will continue to fall as we head towards the end of 2019? Add your thoughts below!

The Rundown


Nyzo version 544 (commit on GitHub) corrects an issue that was causing the sentinel to fail.
This version affects primarily the sentinel. The change, however, involves a core part of the messaging code.
The problem that caused sentinels to fail was simple. In order to avoid blacklisting, many sentinels on 541 or later were not transmitting blocks. The errant code was introduced in version 476, but it did not cause improper behavior until version 541.
In Message, message type NewBlock9 has been removed from the list of disallowed non-cycle types. In version 531, this message type was removed from blacklisting. Enough of the cycle has updated to version 531 or later that blacklisting by the remaining verifiers is much less of a concern than a failure to transmit blocks would be.
While this change is a fix for the transmission problem, the previous code was correct, and it was not the source of the problem.
The actual bug was in the verifierInOrNearCurrentCycle() method call. Instead of checking the sender of the message, the verifier identifier was checked. This meant that a message signed by an in-cycle verifier would be withheld if the verifier identifier was not also in-cycle. Unfortunately, in our sentinel testing for version 541, the verifier identifier on the test system was in-cycle, so this issue was not detected in pre-release testing.
Additionally, the check to avoid sending a message to a verifier with the same identifier as this one has been removed. It was an unnecessary optimization that could interfere with potentially useful communication.
Prior to 541, blocks were transmitted by most sentinels due to a quirk in the code that caused all sentinels to recognize themselves as being near the current cycle. The change in 541 that removed this quirk and caused the sentinel to fail was presented as follows in the version 541 release notes.


Ask your questions
If your question is not here, enter into support section and create a ticket.
Activation
- After a payment request is created, you have 24 hours to wire funds to a designated wallet. Based on the fluctuation
of Bitcoin prices, posted amount of Bitcoin may be larger or smaller. Price updates commence every 30 minutes.
- The system only validates your request to transfer when you pay the designated amount or more. If less bitcoin were submitted, the transfer request would be voided automatically.
- The system only validates your request to transfer when you pay the designated amount or more. If less bitcoin were submitted, the transfer request would be voided automatically.
- The time until the activation varies depending on processing speed of network or blockchain. Some exchange and wallet
may take more time to transfer funds. However, the process generally does not exceed 6 hours. Therefore, if your plan
does not activate after 6 hours, please contact the support centre.
Earnings
- Daily earnings are processed and posted at midnight, Monday through Friday, Korean Standard Time.
- It takes 24 hours until your investments are processed through our system. You will be listed as an FXTRADING dividend recipient after 24 hours.
- The same rules apply for plan upgrades with the purchase of a new plan. Your upgrades will be in force after 24
hours. Until that point, you will receive the earnings on the previous plan.
Withdrawal
- You can withdraw your funds Monday through Friday.
- The minimum withdrawal amount is currently $50. There is no limit on the maximum amount you can withdraw.
- Please allow 1 to 3 business days to process your withdrawal requests.
- It may take up to 24 hours after confirmation for requests to be processed in blockchain and posted on your wallet.
- It generally takes 24 hours for blockchain to recognize hash values. You can review the progress by the link provided
in the e-mail message until then.
Binary
- Upon your purchase of a plan, credits are created. To receive a binary bonus, you must have one referee on each side
of your binary.
- Binary credits are remitted to bonus on the midnight every day, Korean Standard Time.
- Binary credits are remitted to bonus on the midnight every day, Korean Standard Time.
- Please confirm if the new referral member is the first one on your left or right. First referral on each side only
qualifies you for binary bonus program. They do not create credits and do not count as binary members.
- Was your plan active when your referral members in lower tier activate their plans? Credits are provided only if your plan was active when lower tier members activate their plans.
- Are your lower tier referral members’ accounts leadership accounts? Leadership accounts do not own earnings and do not get payments. Therefore, leadership members do not create binary credit.
- Was your plan active when your referral members in lower tier activate their plans? Credits are provided only if your plan was active when lower tier members activate their plans.
- Are your lower tier referral members’ accounts leadership accounts? Leadership accounts do not own earnings and do not get payments. Therefore, leadership members do not create binary credit.
- Created credits are 8% of the price of plans purchased. If a member in your network upgrades a plan, the member only
creates credits on the difference between two plans, not on the entire amount of the plan the member bought. For
instance, if a member upgrades to $500 plan from $300 plan, you would receive 8% of the difference between the two
plans. The difference is $200 in this example so that you will get 16 credits in total.
- There is a rule for the binary program; no member shall receive binary bonus larger than the plan they are on. For
instance, if you are using $100 plan, but have created 150 credits through the binary network, you will only receive
$100 bonus, forfeiting the remaining $50.
- You also need to be careful about 200% earning rule. You can never receive an amount four times more than the plan you are on. For example, if you are using $100 plan, have received $350 as earnings so far and you have 100 credits outstanding for a binary bonus, only $50 that matches your 200% ceiling will be paid to you as a binary bonus.
- You also need to be careful about 200% earning rule. You can never receive an amount four times more than the plan you are on. For example, if you are using $100 plan, have received $350 as earnings so far and you have 100 credits outstanding for a binary bonus, only $50 that matches your 200% ceiling will be paid to you as a binary bonus.
Referral Bonus
- To receive a referral bonus, your plan must be active when your referral’s plan comes activated. To ensure receipt of
your bonus, please wait until your plan gets activated before providing referral codes.
- Referral Bonus is subject to 200% earning rule. Bonus from referrals will be paid up until their earnings reach 200% of their plan price. Bonus ceases to be remitted when your referral member reaches the earning cap.
- Referral Bonus is subject to 200% earning rule. Bonus from referrals will be paid up until their earnings reach 200% of their plan price. Bonus ceases to be remitted when your referral member reaches the earning cap.
- The referral bonus is 6% of the plan price purchased. If your referral member upgrades their plan, it creates the
bonus on the difference between the two plans, not the entire amount of the plan purchased. For example, if your
referral member upgrades to $500 plan from $300 plan, you will receive a 6% bonus on the difference amount between the
plans. In this case, you will receive a $12 bonus as the difference is $200.
- You also need to be careful about 200% earning rule. You can never receive an amount four times more than the plan you are on. For example, if you are using $100 plan, have received $350 as earnings so far and you have 100 credits outstanding for a referral bonus, only $50 that matches your 200% ceiling will be paid to you as a referral bonus.
- You also need to be careful about 200% earning rule. You can never receive an amount four times more than the plan you are on. For example, if you are using $100 plan, have received $350 as earnings so far and you have 100 credits outstanding for a referral bonus, only $50 that matches your 200% ceiling will be paid to you as a referral bonus.


In memoir, Haley alleges disloyalty among some on Trump team
NEW YORK (AP) - President Donald Trump’s former U.N. ambassador, Nikki Haley , alleges in her upcoming memoir that two top administration officials tried to enlist her in opposing some of Trump’s policies.
Haley writes that then-Secretary of State Rex Tillerson and then-White House chief of staff John Kelly were following a “dangerous path.”
In her book, “With All Due Respect,” Haley describes a meeting with Tillerson and Kelly, both of whom had differed with Trump on pulling out of the Paris climate accords and other decisions.
Haley writes that Tillerson and Kelly believed they were trying to “save the country,” but she remembers thinking they were only trying to impose their own beliefs.
“I was shocked,” she writes.
Haley’s book comes out Tuesday. The Associated Press purchased an early copy.

Check that all access to any database containing cardholder data is authenticated. Verify that database access IDs used by applications are not usable by individual users or other applications.
Preventing the database access accounts used by applications from being used interactively or by other processes ensures that if these accounts are compromised, an attacker cannot use them.
Use the following steps to check if database access is authenticated:
Confirm user authentication. Review the settings of each database that stores cardholder data and any corresponding applications to make sure that users are authenticated before access.
Verify that only database administrators may issue database queries or have direct access. Get information about connecting to the database from the database administrator. Attempt to log into the database administration interface with valid non-administrator user credentials. Access should be denied to all users except the administrators.
Verify that application access credentials cannot be abused. Make sure that any authentication credentials used by applications to access any database that stores cardholder data can only be used by the corresponding application(s) and not by users or other processes. Get information about connecting to the database from the database administrator. Attempt to log into the database administration interface with valid credentials used by applications. Access should be denied to interactive logons.
Perform the following actions to assure that database access is authenticated:
Implement functionality to authenticate data access. Program the database application to present the user with a login screen, where the user has to be authenticated before being granted access to the information in the database. Use the authentication credentials from the login throughout the database application for access control.
Secure the database administration interface. Allow only the database administrators to access to the database administration interface(s). Usually a database server allows either a terminal session or a visual administration application to connect to a port and issue SQL queries directly. Authentication credentials usually secure this functionality. Do not make access credentials available for any other users besides the database administrator(s).
Secure the database files. To prevent direct access to the database files, use the access control system implemented by the host Operating System to allow access to database administrator(s) only. If possible, block any computer, besides the administrator's workstation, from accessing the database server administration interface by using a white list. A white list is a list of hosts that are exclusively allowed to access some functionality. On UNIX-style systems, white lists are usually configured by editing the /etc/hosts.allow and /etc/hosts.deny files.
Log access to cardholder data. Instrument the application to log access to the cardholder data. Send the logs to the centralized log server.
Protect the database access credentials used by applications. Allow the access credentials used by the database application to be used by that application only. Do not allow these credentials to be used by users or other processes. This is best accomplished by web applications. If you use a web application, you can configure the database server to use a white list. A white list is a list of hosts that are exclusively allowed to access some functionality while rejecting all access that does not originate form the web application server. On UNIX-style systems, white lists are usually configured by editing the /etc/hosts.allow and /etc/hosts.deny files. If you don’t use a web application and the client application connects directly to the database server, control the interface used by the application to connect to the database. If a database application does not comply with these requirements, the database application will have to be rewritten and possibly redesigned. Considering the costs of redesigning, rewriting and redeploying database applications, it is recommended to consult an expert as early in the design stages as possible to make sure that the resulting application is PCI DSS compliant.

Missions to Mars and beyond experience communication delays with Earth of between 3 to 45 minutes. Due to this, it is impractical to rely on ground-based support and troubleshooting in the event of a power system fault or component failure. Intelligent/autonomous systems are required that can manage the power system in both normal mode and failure mode.
In normal mode, the system would predict energy availability, perform load scheduling, maintain system security and status on-board and ground based personnel. One aspect of overall system autonomy would be solar array characterization, for spacecraft utilizing this technology. One drawback of current satellite systems is the lack of adequate means of determining solar panel or cell status. Being able to automatically characterize solar panel status can enhance energy availability prediction. Similar technology to access that status of battery systems would further enhance these predictions.
In failure mode, the system must identify a fault or failure and perform contingency planning to react or reconfigure the system appropriately to move it back into normal mode of operation, without human involvement. The technologies to detect and identify specific failures in both the generation, distribution and storage systems are needed along with strategies to utilize the failure data to identify recovery strategies for the power system.
With the potential of future manned missions to Mars, this technology will become increasingly important for electrical power management and distribution. Specific areas of interest include:


Located on the island of Wasini, Shimoni is just north of the border with Tanzania. It is an attractive and peaceful place.
All the necessary offices for clearance are in one building in the town.


The only required files are
jQuery and
js/jmpress.js
to use.
For a quick and simple example look at the
examples/simple/index.html
and examples/simple/simple.css.
Currently jmpress.js includes all of the impress.js features and a lot more. To migrate simply add jQuery, change impress.js to jmpress.js and call $(selector).jmpress(); to initialize. Take a look at the impress.js running on jmpress.js example.

An apt-like wrapper for pacman.
In order to run this software, you need Python, it does not matter what version (provided it is updated enough), mspac will only run in Python 3.
You can use pip in order to retrieve the package from PyPI:
sudo pip install mspac
Since version 0.3.4, sync, upgrade and update update the databases and install outdated packages, so there is no difference among them. This is because the recommendations in the pacman documentation about always completely synchronize the system. The command sync is left for backwards compatibility.
mspac [-h] [operation [packages ...]]
Use `mspac -h` to get a complete list of available options. Use '--force' or '-f' to force the operation. The availabe operations at the time of writing are:
mspac sync
mspac autoremove
mspac update
mspac upgrade
mspac install package1 [package2 [package...]]
mspac remove package1 [package2 [package...]]
mspac show package1 [package2 [package...]]
mspac list keyword1 [keyword2 [keyword...]]
The following command will install package1 and package2.
mspac install package1 package2
You can also remove package1 and package2.
mspac remove package1 package2
To update the databases of repositories:
mspac update
Upgrades all packages that are not up-to-date:
mspac upgrade
Updates the repositories and then upgrades all packages that are not up-to-date
mspac sync
Will remove packages that are no longer needed in the system:
mspac autoremove


Dynamic Discovery (D2) is a layer of indirection similar to DNS for the rest.li framework. Functionally speaking, D2 translates a URI like d2://<my d2 service> to another address like http://myD2service.something.com:9520/someContextPath.
Rest.li uses D2 to help decouple a REST resource from the real address of the resource. D2 also acts as a client side load balancer.
Note that D2 is an optional layer in the rest.li framework. In fact, rest.li client can communicate directly to rest.li servers without D2. But D2 provides nice benefits like partitioning, load balancing, and many others. Vice versa, D2 can also be used outside of the rest.li framework. Because in essence D2 is just a name service and a load balancer.
If you just need a quick working tutorial for D2 please refer to Dynamic Discovery Quickstart
As we said above, D2 works like DNS. It translates a D2 URI to a real address. D2 works by keeping the state in Zookeeper. We chose Zookeeper because it's distributed and fault tolerant.
When a client is about to send a request, the D2 client library extract the service name from the d2 URI. Then the d2 client library queries zookeeper for the cluster that owns that service. Once d2 client know the cluster, it will then queries zookeeper for the available URIs for that cluster. Given a list of URIs, D2 client can select which URI to send the request to. The D2 client will listen for any updates related to the cluster and service it previously contacted. So if there's any changes happening either because the server membership changes, or there are new services in a cluster, the d2 client can pick up the changes immediately
Sometimes D2 client's connection to zookeeper might be interrupted. When this happens, D2 will not know what is the latest state so it will assume the state is the same as before. D2 keep backup of the state in the filesystem. If the zookeeper connection interruption happened for a long period of time (configurable), D2 will discard the state and will fail to work.
Running D2 requires a Zookeeper ensemble running somewhere. Please download Zookeeper if you don't have one yet.
As we said above, all the load balancing happened in the client side. D2 client keep tracks of the health of the cluster.
There are 2 types of mode that we can use to load balance traffic.
We aim to alternate between these 2 modes but it’s not always guaranteed.
So how do we choose between CALL_DROPPING and LOAD_BALANCING?
We measure 2 different things for health. One is the cluster health and the other one is the client health.
For cluster health, we only measure the average cluster latency. If the average cluster latency is higher than LoadBalancer’s high water mark, we’ll increment the drop rate by 20%. Drop rate means all traffic to this cluster will be dropped 20% of the time. So obviously cluster health is relevant only to CALL_DROPPING mode. If the cluster latency exceeds high water mark 5 times in a row, we’ll reach 100% drop rate. We have some measure of “recovery mode” to prevent the cluster from getting stuck in perpetual “drop everything” mode. During this mode, we’ll still allow traffic to pass by to calibrate our cluster latency once in a while.
On the other hand, client health is tracked per client. We tracked many things per client e.g. error rate, number of calls, latency of calls, etc. We use this measurement to compute the “computed drop rate” of the client. Healthy client is a client whose latency is lower than client’s high water mark (NOTE that there’s client’s high water mark and there’s also load balancer’s high water mark). For healthy client the computed drop rate should be 0. The computed drop is inversely proportional to the number of virtual points the client gets in a hash ring.
The points are used to distribute traffic amongst many clients. For example there are 4 clients for service “widget”. In perfect condition, each client would have 100 points (this is configurable in service properties). So total points in the hash ring would be 400. If one client’s latency becomes higher than water mark, the computed drop rate will change then the number of points of that client maybe reduced to 80. So that client will receive less traffic and the other servers will get the remaining traffic.
We try to alternate between CALL_DROPPING and LOAD_BALANCING mode. The logic for doing this alternation happens in Load Balancer Strategy.
Here are the moving components that you should know about load balancer:
In the following section we’ll elaborate more of each component:
D2 uses a hierarchy of properties to model the system:
Like its name, ServiceProperties defines anything related to a service. The most important one is the load balancer strategy properties. For example: we can set the highWaterMark and lowWaterMark for this service. If the average latency of all the servers that serves this resource is higher than highWaterMark we’ll start dropping calls because we know the servers are in a “degraded” state.
ClusterProperties define’s a cluster’s name, partioning, preferred schemes, banned nodes, and connection properties.
UriProperties define a cluster name and asset of URIs associated with the cluster. Each URI is also given a weight, which will be passed to the load balancer strategy.
D2 Client is a wrapper over other simpler clients. The real implementation of D2 Client is DynamicClient.java. But underneath we use R2 client to shove bits from client to server. So DynamicClient wraps r2 clients with three classes: TrackerClient, RewriteClient, and LazyClient. The underlying R2 clients are: HttpNettyClient, FilterChainClient and FactoryClient.
The TrackerClient attaches a CallTracker and Degrader to a URI. When a call is made to this client, it will use call tracker to track it, and then forward all calls to the r2 client. CallTracker keeps track of call statistics like call count, error count, latency, etc.
The RewriteClient simply rewrites URIs from the URN style to a URL style. For example, it will rewrite “urn:MyService:/getWidget” to “http://hostname:port/my-service/widgets/getWidget”.
The LazyClient is just a wrapper that does not actually create an r2 client until the first rest/rpc request is made.
There is currently one “true” implementation of a LoadBalancer in com.linkedin.d2.balancer. This implementation is called SimpleLoadBalancer. There are other implementations of LoadBalancer that will wrap this SimpleLoadBalancer for example: ZKFSLoadBalancer. In any case, the simple load balancer contains one important method: getClient. The getClient method is called with a URN such as “urn:MyService:/getWidget”. The responsibility of the load balancer is to return a client that can handle the request, if one is available, or to throw a ServiceUnavailableException, if no client is available.
When getClient is called on the simple load balancer, it:

First tries to extract the service name from the URI that was provided.

 It then makes sure that it’s listening to that service in the LoadBalancerState.

 It then makes sure that it’s listening to the service’s cluster in the LoadBalancerState

 If either the service or cluster is unknown, it will throw a ServiceUnavailableException.

 It will then iterate through the prioritized schemes (prpc, http, etc) for the cluster.

 For each scheme, it will get all URIs in the service’s cluster for that scheme, and ask the service’s load balancer strategy to load balance them.

 If the load balancer strategy returns a client, it will be returned, otherwise the next scheme will be tried.

If all schemes are exhausted, and no client was found, a ServiceUnavailableException will be thrown.

Load balancer strategies have one responsibility. Given a list of TrackerClients for a cluster, return one that can be used to make a service call. There are currently two implementations of load balancer strategies: random and degrader.
The random load balancer strategy simply chooses a random tracker client from the list that it is given. If the list is empty, it returns null. This is the default behavior for dev environment. Because in development environments, one may wish to use the same machine for every service. so with this strategy, we will always return the “dev” tracker client to route the request (and prevent confusion).
The load balancer strategy that attempts to do degradation is the DegraderLoadBalancerStrategy. Here are some facts about the degrader strategy:

D2 currently support range-based and hash-based partitioning.
TODO: add “Partitioning Support for Dynamic Discovery”
Here is an example of the code flow when a request comes in. For the sake of this example, we’ll a fictional widget service. Let’s also say that in order to get the data for a widget resource, we need to contact 3 different services: WidgetX, WidgetY, and WidgetZ backend.
On the server side:

 On the client side:

In D2, a store is a way to get/put/delete properties.
D2 contains two ZooKeeper implementations of DynamicDiscovery. The first is the ZooKeeperPermanentStore. This store operates by attaching listeners to a file in ZooKeeper. Every time the file is updated, the listeners are notified of the property change. The second is the ZooKeeperEphemeralStore. This store operates by attaching listeners to a ZooKeeper directory, and putting sequential ephemeral nodes inside of the directory. The ZooKeeperEphemeralStore is provided with a “merger” that merges all ephemeral nodes into a single property. Whenever a node is added or removed to the directory, the ZooKeeperEphemeralStore re-merges all nodes in the directory, and sends them to all listeners.
In the software load balancing system, the permanent store is used for cluster and service properties, while the ephemeral store is used for URI properties.
The file system implementation simply uses a directory on the local filesystem to manage property updates. When a property is updated, a file is written to disk with the property’s key. For instance, putting a property with name “foo” would create /file/system/path/foo, and store the serialized property data in it. The File System will then alert all listeners of the update.
The in-memory implementation of Dynamic Discovery just uses a HashMap to store properties by key. Whenever a store is put/delete occurs, the HashMap is updated, and the listeners are notified.
The toggling store that wraps another PropertyStore. The purpose of the toggling store is to allow a store to be “toggled off”. By toggling a store off, all future put/get/removes will be ignored. The reason that this class is useful is because LinkedIn wants to toggle the ZooKeeper stores off if connectivity is lost with the ZooKeeperCluster (until a human being can verify the state of the cluster, and re-enable connectivity).
In D2, a registry is a way to listen for properties. Registries allow you to register/unregister on a given channel. Most stores also implement the registry interface. Thus, if you’re interested in updates for a given channel, you would register with the store, and every time a put/delete is made, the store will update the listeners for that channel.
By default, none of the stores in Dynamic Discovery are thread safe. To make the stores thread safe, a PropertyStoreMessenger can be used. The messenger is basically a wrapper around a store that forces all writes to go through a single thread. Reads still happen synchronously.
