mkssd is a package that generates efficient balanced non-aliased multi-level k-circulant supersaturated designs by interchanging the elements of the generator vector. The package tries to generate a supersaturated design that has chisquare efficiency more than user specified efficiency level (mef). The package also displays the progress of generation of an efficient multi-level k-circulant design through a progress bar. The progress of 100% means that one full round of interchange is completed. More than one full round (typically 4-5 rounds) of interchange may be required for larger designs.

Provides the ASUS procedure for estimating a high dimensional sparse parameter in the presence of auxiliary data that encode side information on sparsity. It is a robust data combination procedure in the sense that even when pooling non-informative auxiliary data ASUS would be at least as efficient as competing soft thresholding based methods that do not use auxiliary data. For more information, please see the website <http://www-bcf.usc.edu/~wenguans/Papers/ASUS.htm> and the accompanying paper.

Human infection with avian influenza A(H7N9) virus – update
13 January 2014 -
On 10 January 2014, the National Health and Family Planning Commission of China notified WHO of 6 additional laboratory-confirmed cases of human infection with avian influenza A(H7N9) virus, including 1 death.
Details are as follows:
- 54-year-old man from Nanjing City in Jiangsu Province who became ill on 28 December 2013 and was admitted to the hospital on 5 January. He is currently in serious condition.
- 79-year-old woman farmer from Jiaxing City of Zhejiang Province who became ill on 2 January and was admitted to the hospital on 5 January. She is currently in critical condition. The patient had exposure to poultry.
- 30-year-old male from Ningbo City of Zhejiang Province who became ill on 2 January and was admitted to the hospital on 7 January. He is currently in critical condition. The patient had exposure to poultry.
- 59-year-old woman from Foshan City of Guangdong Province who became ill on 29 December 2013 and was admitted to the hospital on 2 January. She is currently in mild condition.
- 42-year-old woman from Foshan City of Guangdong Province who became ill on 5 January and was admitted to the hospital on 9 January. She is currently in mild condition. The patient works in the poultry wholesale industry
- 38-year-old man from Quanzhou City of Fujian Province who became ill on 3 January and was admitted to the hospital on 8 January. The patient had an underlying illnesses (including tuberculosis and pneumoconiosis) and died on 10 January.
The source of infection is still under investigation. So far, there is no evidence of sustained human-to-human transmission.
The Chinese government continues to take the following measures:
- strengthen surveillance and situation analysis;
- reinforce case management and treatment;
- conduct risk communication with the public and release information;
- strengthen international collaboration and communication; and
- conduct scientific studies.
WHO does not advise special screening at points of entry with regard to this event, nor does it currently recommend any travel or trade restrictions.

| translate_qplot_lattice {ggplot2} | R Documentation |
The major difference between lattice and ggplot2 is that lattice uses a formula based interface. ggplot2 does not because the formula does not generalise well to more complicated situations.
library(lattice) if (require("ggplot2movies")) { xyplot(rating ~ year, data=movies) qplot(year, rating, data=movies) xyplot(rating ~ year | Comedy + Action, data = movies) qplot(year, rating, data = movies, facets = ~ Comedy + Action) # Or maybe qplot(year, rating, data = movies, facets = Comedy ~ Action) # While lattice has many different functions to produce different types of # graphics (which are all basically equivalent to setting the panel argument), # ggplot2 has qplot(). stripplot(~ rating, data = movies, jitter.data = TRUE) qplot(rating, 1, data = movies, geom = "jitter") histogram(~ rating, data = movies) qplot(rating, data = movies, geom = "histogram") bwplot(Comedy ~ rating ,data = movies) qplot(factor(Comedy), rating, data = movies, geom = "boxplot") xyplot(wt ~ mpg, mtcars, type = c("p","smooth")) qplot(mpg, wt, data = mtcars, geom = c("point","smooth")) } # The capabilities for scale manipulations are similar in both ggplot2 and # lattice, although the syntax is a little different. xyplot(wt ~ mpg | cyl, mtcars, scales = list(y = list(relation = "free"))) qplot(mpg, wt, data = mtcars) + facet_wrap(~ cyl, scales = "free") xyplot(wt ~ mpg | cyl, mtcars, scales = list(log = 10)) qplot(mpg, wt, data = mtcars, log = "xy") xyplot(wt ~ mpg | cyl, mtcars, scales = list(log = 2)) qplot(mpg, wt, data = mtcars) + scale_x_continuous(trans = scales::log2_trans()) + scale_y_continuous(trans = scales::log2_trans()) xyplot(wt ~ mpg, mtcars, group = cyl, auto.key = TRUE) # Map directly to an aesthetic like colour, size, or shape. qplot(mpg, wt, data = mtcars, colour = cyl) xyplot(wt ~ mpg, mtcars, xlim = c(20,30)) # Works like lattice, except you can't specify a different limit # for each panel/facet qplot(mpg, wt, data = mtcars, xlim = c(20,30)) # Both lattice and ggplot2 have similar options for controlling labels on the plot. xyplot(wt ~ mpg, mtcars, xlab = "Miles per gallon", ylab = "Weight", main = "Weight-efficiency tradeoff") qplot(mpg, wt, data = mtcars, xlab = "Miles per gallon", ylab = "Weight", main = "Weight-efficiency tradeoff") xyplot(wt ~ mpg, mtcars, aspect = 1) qplot(mpg, wt, data = mtcars, asp = 1) # par.settings() is equivalent to + theme() and trellis.options.set() # and trellis.par.get() to theme_set() and theme_get(). # More complicated lattice formulas are equivalent to rearranging the data # before using ggplot2.


Example Code: Case Structure¶
Overview¶
This example VI demonstrates case structures, including a binary case structure and a multi-state case structure.
Behavior¶
Binary Case Structure
The case structure should show either “This is The True Case” or “This is The False Case” string depending on the initial boolean input (push button).
Multi-state Case Structure
The case structure should show corresponding string output depending on the initial string in the Enum control.
Example Code: For Loop¶
Overview¶
This example VI demonstrates a nested for loop indexing and outputing the elements of a predefined 2-D array.
Behavior¶
The “result” indicator should show the elements of the predefined array one by one each second, while the “inner loop #” and the “outer loop #” shows the current number of iterations in the inner and outer for loop. The program should stop after iterating all the elements in the input 2-D array.
Example Code: While Loop¶
Overview¶
This example VI demonstrates a while loop including a meter and two LEDs (inside and outside loop) that can be controled using the knob and and the push button during execution.
Behavior¶
Once excecuted, the program will keep running until the stop button is pushed. The meter indicator can be adjusted by the knob control in real time. LED2 indicator can be turned on and off by the inside loop push button. However, LED1 can only be turned on by the outside loop push button if it is pushed before execution.

--- layout: post title: 'Adventures in JavaScript: Global Variables and State (Or, how I learned to stop worrying and love closures)' date: '2014-03-01T20:15:00-08:00' tags: [] tumblr_url: http://blog.dishbreak.com/post/78283165612/adventures-in-javascript-global-variables-and ---
About a year ago, I started a job which requires me to do a lot of work in JavaScript and CSS. My previous background was in C++ and Java, very different languages. As the mood tickles my fancy, I’ll share what I’ve learned (and maybe even make it easy to appreciate if you don’t know JavaScript).
As I made the move to JavaScript, I was not a happy camper. I hated the language. Its lack of datatypes and classes led me to write code that was messy, buggy, and hard to keep running. However, as I wrote more and more of it, I realized that I was having so many problems because I was writing JavaScript as if it was a language like C++, when it isn’t. In this post, we’ll go over the concept of maintaining state, and how doing it in JavaScript is very different from doing in it in C++.
One of the most common problems we need to solve in programming is state. State is the answer to the question “what is the system doing right now?” Depending on what state a system is in, we want to have different behavior occur.
Ok, that was a little abstract. Let’s consider something a little more specific–a television remote. If you look at the remote for a television, odds are you see a single power button. It’s pretty intuitive what that button does. If you press it when the TV is on, the TV turns off. Press it when the TV is off, and it turns on. Pretty simple, right?
In the TV example, there are two states for the TV: on and off. When you press the power button on the remote, what you are really telling the tv to do is go to the next state. What you see happening when you push that button is totally dependent on what the current state and the next state are.
The power button isn’t the only button on the remote that’s state dependent. Nearly every button on that remote is–volume up/down, channel up/down, input, etc. What each of those buttons do is totally dependent on what the TV is doing right now.
Languages like C++ and Java are totally down to maintain state. As a matter of fact, it’s core to their functionality. In these languages, we use objects to organize everything–functions, variables, the whole lot. Object-oriented programming (OOP) languages are a topic of discussion all in and of themselves, but the important thing to remember here is that OOP languages make it really easy to maintain state.
If you’re willing to look at some C++ code, check out the following, otherwise, click here to skip on past it.
For those with some C++ familiarity, this is how our Television might look in C++:
class Television
{
public:
Television();
~Television();
void pressPowerButton();
private:
bool tvIsOn; //state variable
void turnOn();
void turnOff();
};
There’s a lot going on here, so let’s take this apart. What we’re looking at is a class declaration in C++. Here’s what the code is saying:
Television
.Television
, you can do exactly one thing with it–press the power button (hence, pressPowerButton()
). We know this because pressPowerButton()
is in the public
section of the declaration.tvIsOn
, and two functions: turnOn()
and turnOff()
. These are things that you can’t mess with when you create the object. That’s why they’re in the private
section of the declaration.tvIsOn
is a boolean variable, which is a really fancy way of saying “this variable can only be true or false”. If tvIsOn
is equal to “true”, that means our TV is in the “on” state. Otherwise, it’s in the “off” state.This is a key feature of an OOP language. An object has two kinds of stuff: things you can mess with (like pressPowerButton()
), and things you can’t touch (like turnOff()
). If you think about it, this is a lot like a real TV. If you press the power button on your TV, it just works. Unless you know what you’re doing, you really shouldn’t be opening up the TV and messing with its insides–there’s a lot of stuff in there that needs to be left alone in order for the TV to work.
Continuing on, let’s look at the definition.
Television::Television()
{
//on creation, the television is off.
tvIsOn = false;
}
Television::~Television()
{
}
void Television::pressPowerButton()
{
tvIsOn = !tvIsOn;
if (tvIsOn == true)
{
turnOn();
}
else
{
turnOff();
}
}
void Television::turnOn()
{
//do stuff to turn on
}
void Television::turnOff()
{
//do stuff to turn off
}
This is what’s called a class definition. It’s the counterpart to the class declaration we just showed. It basically just explains what all the functions we named in the declaration actually do. There’s a few salient things here:
The astute reader will note that I didn’t put any code in the turnOn()
and turnOff()
functions. That’s because this Television is a made-up example, and I couldn’t be bothered to make up the code for them.  It just matters that they exist and that we know when to use them.
To use our first television in C++, we just do this:
//create the TV
Television * tv = new Television();
//press the tv pwr button
tv->pressPowerButton();
...
//later on, press the tv pwr button again
tv->pressPowerButton();
Whoa, nelly, what just happened there? Well, we first create the tv, using this line:
Television * tv = new Television();
Then, we decide to press the power button to turn it on.
tv->pressPowerButton();
The tv is in the “off” state before we press the button. When we press the button, it goes to the “on” state and turns on.
After we’re done using it, we decide to turn it off. So we press the power button again in the same way.
tv->pressPowerButton();
The only difference is that now, the tv was in the “on” state before we pressed the button. Now, it goes to the “off” state and turns off.
Groovy. But what if we have other TV’s? Like say, one in the bedroom. No problem!
//create the TV
Television * tv = new Television();
//create the other TV
Television * tv2 = new Television();
//press the first tv's pwr button
tv->pressPowerButton();
//press the other tv's pwr button
tv2->pressPowerButton();
What we’ve done here is create two separate objects. Each object has its own state variable and its own pressPowerButton()
function. Because the state is private, the user can’t mess with them, either. This means I can’t accidentally move my tv to the “off” state if it’s on without using the pressPowerButton()
function. This phenomenon where each object has its own state and hides it from the user is called encapsulation, and it’s a powerful concept.
Ok, so let’s imagine my television on a webpage. I’d have HTML that shows how to draw the webpage. It might look like this:

The tv is off!

<button id="tv_pwr_button">Power Button</button>
The span called tv_state
will tell me what the state of my TV is. The button named tv_pwr_button
will be the power button of my TV. Now, to make the “television” do stuff, we need to use JavaScript. I’m going to make my life easy and use jQuery, a JavaScript library that makes doing these things a lot easier. In jQuery, the code to make the TV work might look like this:
var tvIsOn = false;
$("#tv_pwr_button").click(function () {
tvIsOn = !tvIsOn;
if (tvIsOn == true)
{
$("#tv_state").html("on");
}
else
{
$("#tv_state").html("off");
}
});
It’s a lot like the C++ example. When I click the button, I change the state of the TV, and act accordingly. You can see an example of this here:
Cool. But there’s a slight issue. To demonstrate it, I’ll add another TV.
Huh. That’s odd. If you click one button, then the other, sometimes nothing happens! The buttons just stop working properly. What happened??
The answer lies in our JavaScript. If we look at the code, we have a single state variable, tvIsOn
. When we press either button, that state changes. Oops.
Wait, why is that? Why can anything change the state? Because the state is what’s called a global variable.
In order to explain what a global variable is, I need to talk about a concept called scope. The best explanation I can come up with is that the scope of a variable tells you how much code can mess with the value of that variable.
In our C++ code, everything in the Television class had a nicely defined scope. For example, pressPowerButton()
was scoped to the user, and everything else was scoped to the class. This means that only code inside the Television class can mess with the tvIsOn
state variable.
Global variables are nuts because they are scoped to everything. Any piece of code that is running in your program can change that variable. This means you can easily change a global variable by accident.
In JavaScript, any variables that appear outside a function are automatically global. This is a problem for C++ developers, who are used to having to go out of their way to make a variable global. If you meet a developer who’s making the transition from OOP to JavaScript, chances are they’ve got a lot of global variables in their code (I know I did in mine).
In JavaScript, we don’t really have nice access to classes like we do in C++ (without using Object.prototype
, but that’s a lesson for another day). So how do we fix our code so we have multiple TVs working? After all, I need to play my Xbox.
One easy thing to take advantage of is local variables within a function. Consider the following example:
function countTo(number) {
for (var i = 0; i <= number; i++) {
console.log(i);
}
}
function countToInDiv(number, div) {
for (var i = 0; i <= number; i++) {
div.append(i);
}
}
Now, what the code is doing isn’t important. What is important to notice, is that both countTo
and countToInDiv
use variables named i
and number
. Hold the phone! Isn’t this a problem? Wasn’t this what caused our example with two tv’s to fail?
No. Because in this case, number
and i
are scoped only to the function they’re in. So, the number
and i
in countTo
are totally separate from the number
and i
in countToInDiv
. If this sounds familiar to you, it should–it’s the same sort of encapsulation we got with the C++ classes earlier, just with JavaScript.
This is an important lesson to learn: JavaScript does provide a lot of the features we’re used to in OOP languages, it just does it in a different way.
So, what if we tried wrapping the code for the TV in a function, and then call that function in our main code? Something like, say, this:
function initializeFirstTv() {
var tvIsOn = false;
$("#tv_pwr_button").click(function () {
tvIsOn = !tvIsOn;
if (tvIsOn == true)
{
$("#tv_state").html("on");
}
else
{
$("#tv_state").html("off");
}
});
}
function initializeSecondTv() {
var tvIsOn = false;
$("#tv_pwr_button2").click(function () {
tvIsOn = !tvIsOn;
if (tvIsOn == true)
{
$("#tv_state2").html("on");
}
else
{
$("#tv_state2").html("off");
}
});
}
initializeFirstTv();
initializeSecondTv();
Well, see for yourself!
Yahoo! The code works exactly as it should, because each TV has its own state.
I should probably note that this is hardly the best way to code, but since the demand for my web-based “televisions” is probably really low, I think it’s okay in this case. ;)
The important thing to note here is using closures helps us keep our code clean and limit the scope of variables we care about.
JavaScript is a language all of its own, and it needs to be treated that way. While it may not look like it on the outset, it is a fully-featured and modern language. It’s also the wave of the future, as web applications take over more and more of our daily computing experience.
The fact of the matter is that you cannot write code as if you were developing in JavaScript. You wouldn’t go running in high-heels, nor would you show up at a fancy gala in running shoes. JavaScript and OOP languages have their places, but it’s up to the developer to take full advantage of the language they’re in


I’ve posted before about how I converted this site to Jekyll and hosted it on Github Pages. I’m a huge fan of this and it was really exciting last year when they announced support for https with Github pages. But alas, this is for the github.io
urls, not custom domains. I’m to the point now where I do not want to wait any longer if there are other solutions out there. I would like to avoid the impending Chrome death mark, as well as start testing out and using service workers with this site. As it turns out, there is a pretty simple way of doing this using Cloudflare.
What is Cloudflare
In a nutshell, it’s a service for a proxy that lies between origin (your server) and the user. This allows you to serve cached content from their edge CDN servers all over the world, mitigate DDOS attacks, and add SSL support, among many other things.
How?
There are plenty of tutorials out there on how to do it, here’s a great one here. But if you already have github pages set up, then it just comes down to a few steps:
- Create a Cloudflare account or log in
- Create a new site (even if you did this a long time ago, the new creation steps may have changed)
- It will walk you through and scan your DNS settings. Make sure your A or CNAME settings are correct in Cloudflare once it’s done.
- Change your nameservers of your domain to match the ones Cloudflare gives you.
- Change your SSL settings for your site to use “Full”.
- Set a page rule to redirect all traffic to https. I used
http://*ttdavis.com/*
toAlways use HTTPS
.
And that’s it! It will most likely take a few hours to update, which sucks because your site will be down in the mean time. But at least it’s simple and it’s free! Now with Cloudflare, Jekyll, and Github Pages, you get free hosting and free SSL certs. 🍻

Overview
This article explains how you can back up container directories and databases (specifically PostgreSQL) to your localhost. It also goes through the process of how to restore from a backup.
Prerequisites
This article assumes that you have a UKCloud for Red Hat OpenShift envrionment and can access it using the OpenShift Container Platform command line interface.
This article uses the following two OC CLI commands:
Begin by logging into your UKCloud for Red Hat OpenShift envrionment using the following command:
oc login --server {server} --token {token here}
Tip
You can retrieve the --token
by logging into the OpenShift web interface, clicking your username in the top right and clicking Copy Login Command.
Backing up container directories to your local client
Create a directory on your local client for files to be backed up to:
mkdir ~/oshiftbackups
Switch to the project in which the container you want to back up the directory from is located:
oc project {project name}
Tip
To list all projects use:
oc projects
.Identify the pod in which the container you want to back up resides:
oc get pods
Using
oc rsync
, copy the directory you want to back up:# oc rsync usage: oc rsync {podname}:{path/to/directory} {destination/on/host} # Example usage: oc rsync {podname}:/tmp/files/ ~/oshiftbackups
Note
If you have multiple containers in a pod, use the
-c {container name}
parameter to specify a specific container name.Example:
oc rsync {podname}:{path/to/directory} {destination/on/host} -c {container name}
Uploading a directory to a container
Switch to the project in which the container you want to upload the directory to is located:
oc project {project name}
Tip
To list all projects use:

Using
oc rsync
, upload the directory to the container:# oc rsync usage: oc rsync {destination/on/host} {podname}:{path/to/upload} # Example usage: oc rsync ~/oshiftbackups/files mypod-1-hscwm:/tmp/files
Note
If you have multiple containers in a pod, use the
-c {container name}
parameter to specify a specific container name.Example:
oc rsync {podname}:{path/to/directory} {destination/on/host} -c {container name}
Backing up a database on OpenShift
In this example, the type of database being backed up is PostgreSQL. Substitute the commands executed in this article (using oc exec
) with commands that are appropriate to the database type you're using.
Create a directory on your local client for files to be backed up to:
mkdir ~/oshiftdatabasebackup
Switch to the project where your database pod is located:
oc project {project name}
Tip
To list all projects use:
oc projects
.Identify the pod in which the database container you want to backup resides:
oc get pods NAME READY STATUS RESTARTS AGE postgresql-1-hscwm 1/1 Running 0 31m # In this example, the database is running in pod: postgresql-1-hscwm
Using
oc exec
, run the following command to execute the PostgreSQL backup command in the container:# Execute a remote command on a container # Dump the contents of the database and pipe it into gzip (to create a compressed archive) # oc exec usage: oc exec {podname} -- bash -c 'pg_dump {databasename} | gzip > /opt/app-root/src/{databasename}.gz' # Example usage: oc exec postgresql-1-hscwm -- bash -c 'pg_dump sampledb | gzip > /opt/app-root/src/sampledb.gz'
Using
oc rsync
, copy the database backup file contaning the PostgreSQL database files to your local client:# oc rsync usage: oc rsync {podname}:{path/to/directory} {destination/on/host} # Example usage: # This command copies the database backup file to /home/databasebackup oc rsync postgresql-1-hscwm:/opt/app-root/src/sampledb.gz ~/oshiftdatabasebackup
Note
If you have multiple containers in a pod, use the
-c {container name}
parameter to specify a specific container name.Example:
oc rsync {podname}:{path/to/directory} {destination/on/host} -c {container name}
Your database is now backed up onto your local client in /home/oshiftdatabasebackup
.
Restoring a database on OpenShift
Using
oc rsync
, move the backup of the database onto the container:# Copy the directory (oshiftdatabasebackup) containing the compressed archive to the container mount point oc rsync ~/oshiftdatabasebackup {podname}:/var/lib/pgsql/data # Example usage: oc rsync ~/oshiftdatabasebackup postgresql-1-hscwm:/var/lib/pgsql/data
Note
If you have multiple containers in a pod, use the
-c {container name}
parameter to specify a specific container name.Example:
oc rsync {podname}:{path/to/directory} {destination/on/host} -c {container name}
Using
oc exec
, extract the database archive and restore the database:In this example, the type of database being restored is PostgreSQL. Substitute the commands executed in this article (using
oc exec
) with commands that are appropriate to the database type you're using.# Import the database backup and remove the backup directory from the container oc exec {podname} -- bash -c 'gunzip /var/lib/pgsql/data/oshiftdatabasebackup/{databasename}.gz | psql {databasename} && rm -rf /var/lib/pgsql/data/oshiftdatabasebackup' # Example usage: oc exec postgresql-1-hscwm -- bash -c 'gunzip /var/lib/pgsql/data/oshiftdatabasebackup/sampledb.gz | psql sampledb && rm -rf /var/lib/pgsql/data/oshiftdatabasebackup'

Research track represents the segment that can push our lives to the better. Through research, you can work on the demonstration of new systems that can open the doors to great technological breakthroughs. For me, it 's more pleasant and joyful to work on research projects more than being obligated to do a certain job and be constrained by certain limits.
Starting after graduation is a delusion, imagine that you are competing with 7000 engineer with the same skills and technicalities. You'll never have a chance to be selected for a good job. You should start while you are in the University, where you have plenty of time to work in projects, do civil activities and voluntary work. That's in addition to learning the needed technical skills that are not delivered in college.
Two crucial skills freelancers must have are: self-learning and self-discipline. Nobody forces you to work or learn or gain experience. You set goals and stick to them no matter what. If you can't do that, you're doomed to fail before you even start."
Throughout extensive informative sessions given by HR professionals and prominent speakers, you will get an all-inclusive view of the process that follows graduation. Starting from preparing a CV, creating a catchy LinkedIn profile, to finding the right job and acing the HR interview.
Interactive workshops will help you take a good grip on essential soft skills that will help you pave the way of your professional development. Communication skills, leadership skills, team management and workplace ethics are important skills to earn if you’re willing to pursue an exceptional career.
“The Great Aim of Education is Not Knowledge, But Action.”
Getting a real life experience is the most efficient learning tool. In our Mock-Interviews, you will be interviewed by professional
HR specialists who will provide you with a detailed assessment of your performance.

In the context of software or information modeling, a happy path is a default scenario featuring no exceptional or error conditions.
Amazing, 7 Eleven launch mobile payment app: a day after launching it attackers stole half a million USD from customers, as the app had no security around password reset (any user could reset anybody else’s password) https://t.co/EyBrcFYMlL

Not exactly. Code releases go through a CI process and geographic/customer segment tiered rollout. On the other hand, WAF Rules are generally more like a configuration language. We push them out to respond to new attack threats. Customers expect them to be live globally quickly.

All of these situations arose because software was made to do something that the humans writing it had not considered.
Undergone PCI compliance training for client.
Had conversations where unknowns were present.
Regular Tuesday when I deal with an API that just goes away.
It's what makes WordPress extensible.
Also what makes WordPress very easy to break.
Every single esc_*
function in WordPress is there because of this.
Additioanally wp_kses_*
and the PHP native strip_tags()
functions.
Let's handle payment with a card through an API (Stripe for example)
You post some data, and you get some data back, for example an autocomplete service.
What happens if that service starts returning poisoned payloads?
But also it's just a good practice anyways. Suggestions:
Removed bits first.
WC_Order_Factory::get_order( $order_id );
$classname = apply_filters(
'woocommerce_order_class',
$classname,
$order_type,

add_filter( 'woocommerce_order_class', function() {
return 'NoSuchClass';
} );

}
return new $classname( $order_id );

// false is returned
👍

}

add_filter( 'woocommerce_order_class', function() {

} );
But why would anyone DO THAT?!
Can you mathematically PROVE that that won't happen? Nope. So handle it.
Software fails gracefully, enters a state where it can either restart itself, or tell the user that it failed, why it failed, and what to do to not fail again.
All without preventing further work.
Lack of time
Lack of management buy-in
And...
Yeah people who are mocking CO's security people are being meanie poo heads. 99% of the time there's a glaring sec flaw there's an email from an exasperated engineer saying "THIS IS ALL BAD" and someone replying "we accept the risk"
— The Cyber (@r0wdy_) July 30, 2019
Exactly that. Many good orgs carry a metric ton of risks because the organisation has chosen to accept them, I don’t think people realise
— Kevin Beaumont (@GossiTheDog) July 30, 2019
People should never take my tweets as laughing at InfoSec teams btw, as I’m in the trenches doing same thing. It’s a good learning moment tho

C++ and C++'0x Support in Clang
Last updated: $Date: 2010-08-26 09:20:18 -0500 (Thu, 26 Aug 2010) $
Clang currently implements all of the ISO C++ 1998 standard (including the defects addressed in the ISO C++ 2003 standard) except for 'export' (which has been removed from the C++'0x draft). However, the implementation of Clang C++ is still somewhat immature, with remaining bugs that may cause compiler crashes, erroneous errors and warnings, or miscompiled code. The LLVM bug tracker contains a Clang C++ component that tracks known Clang C++ bugs.
Projects Building with Clang
Clang is now capable of compiling large C++ projects, and the following table describes various projects that we have attempted to compile with Clang++.
| Project | Status | Last Tested | Tracking Bug |
|---|---|---|---|
| Clang and LLVM | Successful self-hosting achieved | Continually | |
| CMake | Compiles, passes regression tests (debug build) | February 9, 2010 | |
| Boost | Compiles and passes regression tests on Darwin/X86-64. | May 20, 2010 | |
| Qt | Partially compiles; miscompilation of uic prevents complete compilation, qmake works, some small examples also. | February 9, 2010 | PR5881 |
C++0x Implementation status
Clang's development effort is focused primarily on fixing bugs in the current ISO C++ standard (1998/2003). This section tracks the status of various C++0x features.
Implementation Status by Feature
The following table is used to help track our implementation progress toward implementing the complete C++'0x standard. We use a simple, somewhat arbitrary color-coding scheme to describe the relative completeness of features:
| Not started/not evaluated | Not Applicable | Broken | Some examples work | Many examples work | Nearly everything works | Complete | Complete (with tests for each paragraph) |
|---|---|---|---|---|---|---|---|
| N/A | ✓ |
A feature is "complete" when the appropriate Clang component (Parse, AST, Sema, CodeGen) implements the behavior described in all of the paragraphs in the relevant C++'0x draft standard. The major components are:
- Parse
- Clang is able to parse the grammar of this feature (or the grammar
described by this section), but does not necessarily do anything with the
parsed result. Use Clang's
-fsyntax-only
option to parse C++ programs. - AST
- Clang builds an abstract syntax tree (AST) for the feature, but does not
necessarily perform any type-checking. Use Clang's
-ast-print
option to print the resulting ASTs. - Sema
- Clang parses and type-checks this feature and provides a well-formed AST
annotated with types. Use Clang's
-fsyntax-only
to type-check code. - CodeGen
- Clang parses, type-checks, and generates code for this feature, allowing one to compile and execute programs.
Updates to this table are welcome! Tests for the various features are also welcome!
| C++0x Features | |||||
| Feature | Parse | AST | Sema | CodeGen | Notes |
|---|---|---|---|---|---|
| Explicit conversion operators (N2437) | No name mangling; ASTs don't contain calls to conversion operators | ||||
| Static assertions (N1720) | N/A | ||||
| Deleted functions (N2346) | N/A | ||||
| Rvalue references (N2118 + N2831) | |||||
| nullptr (N2431) | |||||
| Right angle brackets (N1757) | N/A | N/A | N/A | ||
| Decltype (N2343) | ✓ | ✓ | ✓ | N/A |
