CDT Overview
The C/C++ Development Toolkit (CDT) is a set of Eclipse plug-ins that provide C and C++ extensions to the Eclipse workbench. For more information about Eclipse, see Workbench User Guide > Concepts > Workbench.
The CDT provides a C/C++ IDE that simplifies many of the same tools that you can use from the command line. The CDT can also communicate with many external utilities and interpret their responses, for example:
- Build (such as make).
- Compile (such as gcc). For more information, see http://gcc.gnu.org.
- Debug (such as gdb). For more information, see http://sources.redhat.com/gdb/.
The CDT opens as the C/C++ perspective of the Eclipse workbench. The C/C++ perspective consists of an editor and the following views:
- Project Explorer
- Shows all of the file system's files under your workspace directory.
- Console
- Displays your program's output, as well as the output from your build and external tool chain.
- Editor
- The C/C++ editor view provides specialized features for editing C/C++ related files.
- Make Targets
- Enables you to select the make targets you want to build in your workspace.
- Outline
- Displays the structure of the file currently open in an editor.
- Problems View
- If you encounter any errors during a build they will be displayed in the Problems view.
- Properties
- Shows the attributes of the item currently selected in a view or an editor.
- Search
- Shows the results of searches for files or text.
- Tasks
- Lists tasks that you want to keep track of, either as a schedule of things to do or a history of things that have been done.
For more information, see Workbench User Guide > Concepts > Perspectives.
CDT updates
The Install/Update wizard provides information about your current Eclipse installation and provides the framework to manage your updates. For more information, see Workbench User Guide > Tasks > Updating and installing software.

Discrimination
Algorithms are often used to supplement or make decisions in a way that “optimizes'' some objective; often, these decisions are made under limited resource constraints specific to the given domain. The MD4SG group on Discrimination and Equity in Algorithmic Decision-making focuses on understanding how these optimization choices, constraints, and mechanisms impact different stakeholders of algorithmic systems. This group has larger biweekly meetings, as well as smaller project subgroups focusing on different research areas such as understanding the impacts of ranking problems and design of resource allocation mechanisms. Larger biweekly group meetings will discuss topics including, but not limited to, long-term effects and feedback loops, impacts of resource constraints, implications of discrimination metrics, and contextualization across different domains such as education, hiring, and the gig economy.

SinglySDK Reference
Singly iOS SDK
A simple SDK for accessing Singly from iOS apps.
The Singly SDK is currently in active development and as such should be considered alpha quality at this stage. We are very interested in feedback from the community about the direction you would like to see us take with it. Please follow with us as we push towards our 1.0 milestone.
Getting Started
The first thing you will need is a Client ID and a Client Secret for your application from Singly. If you have not done so already, add your application by signing in to Singly. Your Client ID and Client Secret can be found on the application settings page for your application.
Once you have your Client ID and Client Secret, we can either start a new iOS application or use an existing one.
Linking to the Singly SDK
Opening a Session to Singly
To start using the Singly SDK in your project, you will first need to
initialize the SinglySession
. You’ll probably want to do this in your
application delegate right after the application has finished launching, such
as in the application:didFinishLaunchingWithOptions:launchOptions
method.
```objective-c SinglySession *session = [SinglySession sharedSession]; session.clientID = CLIENT_ID; session.clientSecret = CLIENT_SECRET;
[session startSessionWithCompletionHandler:^(BOOL ready) {
if (ready) {
// The session is ready to go!
} else {
// You will need to auth with a service...
}
}]; ```
The SinglySession
has two other properties:
accessToken
– Your Singly Access Token. You should not need to access this unless you really need to do something that does not fit into the current Singly SDK.accountID
– Your Singly Account ID.
Both of these are saved between runs in the NSUserDefaults
and should be
setup using SinglyService
or a SinglyLoginViewController
instance.
Using the Singly Login View Controller
```objective-c SinglyLoginViewController *loginViewController = [[SinglyLoginViewController alloc]
initWithSession:[SinglySession sharedSession]
forService:kSinglyServiceFacebook];
[self presentModalViewController:loginViewController animated:YES]; ```
The service that you define can be any string of the services that Singly supports, but we have these defined as constants for you in the SinglyConstants.h.
An example implementation of the SinglySessionDelegate
is:
```objective-c – (void)singlySession:(SinglySession )session didLogInForService:(NSString )service {
[self dismissModalViewControllerAnimated:YES];
// We're ready to rock! Go do something amazing!
}
- (void)singlySession:(SinglySession )session errorLoggingInToService:(NSString )service withError:(NSError )error { UIAlertView alert = [[UIAlertView alloc] initWithTitle:@“Login Error” message:[error localizedDescription] delegate:self cancelButtonTitle:@“OK” otherButtonTitles:nil]; [alert show]; [self dismissModalViewControllerAnimated:YES]; } ```
Using the Singly Login Picker
If you wish to login multiple services, or offer multiple services for login,
then you can use the SinglyLoginPickerViewController
.
``` SinglyLoginPickerViewController *pickerViewController = [[SinglyLoginPickerViewController alloc]
initWithSession:[SinglySession sharedSession]];
[self presentModalViewController:pickerViewController animated:YES]; ```
Making API Requests
Once we have a valid session we can start making API requests. We can make
GET, POST or any method requests using the SinglyAPIRequest
. The request is
only a description of the request that we are going to make, to actually
execute the request we use our session and one of the requestAPI:
methods.
An example that requests the profiles list and is using blocks to handle the
result is:
```objective-c [[SinglySession sharedSession] requestAPI:[SinglyAPIRequest apiRequestForEndpoint:@“profiles” withParameters:nil] withCompletionHandler:^(NSError *error, id json) {
NSLog(@"The profiles result is: %@", json);
}]; ```
That’s the basics and enough to get rolling!
Building the Example App
Singly SDK ships with an example app that illustrates all of the capabilities of the SDK.
Configure the Example App
Before you can build and run the example app, you will need to provide your
Client ID and Client Secret in SinglyConfiguration.h
.
Enable Native Facebook Authorization (optional)
See the instructions below (under “Native Facebook Authorization”) to enable testing of the Facebook application fallback attempt.
Build and Run!
Once you have things configured, simply build and run the project in the Simulator.
If you wish to run the example on your iPhone or iPad, you will need to configure the project with provisioning appropriate to your device and Apple developer account, which is beyond the scope of this document.
SDK Documentation
After you’ve cloned the project, you will find generated documentation in
the SinglySDK/Documentation
folder. This documentation is automatically
regenerated with each successful build of the framework in Xcode, provided
you have (appledoc)[http://gentlebytes.com/appledoc/] installed.
Native Facebook Authorization
Singly SDK interfaces directly with the device to support authorization on iOS 6+ and will attempt to fallback to the installed Facebook application and then the built-in Singly web-based authorization. In order for the Facebook application fallback to work, you will need to perform the following steps:
Register your app to handle Facebook URLs
You must add the following to your Info.plist, replacing the 0’s with your actual Facebook App ID:
```xml
<dict>
<key>CFBundleURLSchemes</key>
<array>
<string>fb000000000000000</string>
</array>
</dict>
```
Configure your app delegate to handle launches by URL
When native integration is not possible, we fall back to launching the Facebook app (if installed) in order to complete the auth workflow. In order for this to happen, you will need your application delegate to implement the following method in order for the round-trip process to complete:
```objective-c – (BOOL)application:(UIApplication *)application
openURL:(NSURL *)url
sourceApplication:(NSString *)sourceApplication
annotation:(id)annotation
{ return [[SinglySession sharedSession] handleOpenURL:url]; } ```
Need Help?
We are available to answer your questions, help you work through integration issues and look into possible bugs with our service and SDKs.
Found a bug? If you think you have come across a bug in the SDK, please take a moment to file an issue, providing as much information about the issue as possible.
Join us on HipChat. For questions or just to say hi and show off what you’re building, feel free to join us on our Support HipChat and have a word with us!

MotoGP 2019: Maverick Vinales dominates the Malaysian GP
by Team ODSpaniard Maverick Vinales (Monster Energy Yamaha MotoGP) was well placed to win the Malaysian GP at the Sepang International Circuit, after a second position in qualifying, and led the race from lights to flag. The dominating victory makes it his second win of the season. Pole-sitter Fabio Quartararo (Petronas Yamaha) finished in seventh.
In second place, with a miracle charge up the field from 11th on the grid, was the 2019 MotoGP World Champion Marc Marquez (Repsol Honda), who finished the race a little over 3 seconds behind Vinales. Marquez gained second position before the first lap of the Malaysian GP was complete, making full use of a great start to join the pack at the front at Turn 1 itself.
With this second place, he has already set a new record (395 points) for the most championship points scored in a single season, beating previous record holder Jorge Lorenzo's 383 point tally. Marquez sealed his championship victory at the last round in Thailand.
Rounding off the podium was Andrea Dovizioso (Ducati Corse) who had qualified tenth on the grid. The Italian rider battled it out with local favourite, Valentino Rossi (Monster Energy Yamaha MotoGP) right until the close of the race, with barely three tenths of a second separating the two at the chequered flag. The MotoGP circus will move to Valencia for the last round of the season.

A fix to my previous post:
The last character in the last regexp should be an '*' instead of the '?':
Replace:
var str = (path + '').replace(/^[\/\\]+$/, '').replace(/^.*[\/\\]([^\/\\]+)[\/\\]?/g, '$1');
With:
var str = (path + '').replace(/^[\/\\]+$/, '').replace(/^.*[\/\\]([^\/\\]+)[\/\\]*/g, '$1');

Note that when the input ends with one or more slashes, PHP ignores them and returns the word before them.
'///b///' result is 'b'
'///\\//' result is '' (an empty string)
To return values like PHP the code should be:
function basename(path, suffix) {
var str = (path + '').replace(/^[\/\\]+$/, '').replace(/^.*[\/\\]([^\/\\]+)[\/\\]?/g, '$1');
if (typeof suffix === 'string' && str.substr(str.length - suffix.length) === suffix) {
return str.substr(0, str.length - suffix.length);
}
return str;
}

@ Pedro: Actually, this is expected behavior. If you try this in PHP it will also return ecra.php?p=1
This may not make a whole lot of sense from the browser point-of-view; but we also have to consider other JavaScript platforms like V8, rhino, and stuff built on that like node.js
This is the one of the reasons we chose to always stick with PHP's implementation. At least developers know what to expect; and in theory you should be able to run PHP code in PHP.JS without worrying about different implementations & stuff blowing up in your face.
So I'm sorry to say Pedro, you're going to have to parse this like you'd otherwise have to in PHP as well.
Pedro
on 2009-09-21 00:33:52
Hello there.
I would like to report that basename should stripdown what's in front of the ?. By applying basename to a url like this:
ecra.php?p=1
It should return "ecra.php" only.
I've tested the following way:
var path = window.location.href;
console.log(basename(path));
Please note:
With window.location.pathname this issue does not apply.

@Kevin: Sweet! Thanks for handling that! Yes, I think it should work just fine for content... Btw, while there's no harm in it, we don't strictly need to "dual license" since the MIT license is compatible with GPL (though not vice versa)--you can just use MIT and it will work for GPL users, though I guess maybe it avoids GPL users having to copy-and-paste the MIT clause info...
Kevin van Zonneveld
on 2009-07-24 12:04:09
@ Brett Zamir: I manually changed the license now. It's the same as PHP.JS'. Will this license work for content as well as code you think?
Brett Zamir
on 2009-07-19 01:46:27
@Albert Martin, Thanks for offering. Although we only intend to use functions in the library which adhere to PHP behavior (unless it seems to warrant a configuration which can be changed with ini_set()), you might consider adding your function to http://phpjs.org/wiki . Kevin, it looks like by your removing the specific license, Mediawiki has defaulted to GNU Free Documentation License for the wiki. Do you recall if there was a way to configure it otherwise?
Albert Martin
on 2009-07-18 09:05:41
I needed also to remove the extension, no matter what filetype it is. So if you set suffix==true, it removes any, not the one specified:
function basename(path, suffix) {
//...
var b = path.replace(/^.*[\/\\]/g, '');
if (typeof(suffix) == 'string' && b.substr(b.length-suffix.length) == suffix) {
b = b.substr(0, b.length-suffix.length);
} else if (suffix == true && b.indexOf('.') != -1) {
b = b.substr(0, b.lastIndexOf('.'));
}
return b;
}

@ Nate: Thanks a lot Nate! I did struggle to get the regexes to work though (syntax issues). I finally felt like taking a completely different approach (I hope you don't mind man), and by means of an experiment, I took a look at the original php5 C code and tried to recreate it from there.
Of course I kept the credit for your original intact!

Hi. I created a pathinfo() function.
function pathinfo(path, options)
{
var re = /(([^\\/]*?)(?:\.([^.]*))?)$/;
var re2 = /(.*)[\\/]/;
var path_arr = re.exec(path);
var dir_arr = re2.exec(path);
// To be PHP compatible, no directory becomes "."
if (dir_arr == null || dir_arr == "") dir_arr = ["","."];
var path_obj = {dirname:dir_arr[1],basename:path_arr[0],extension:path_arr[3],filename:path_arr[2]};
if (typeof options == "undefined") {
if (path_obj.extension == "" && path_obj.filename.slice(-1) != ".") {
// To be PHP compatible, if there is no dot (.) in the name, the extension value is not set.
delete path_obj.extension;
}
return path_obj;
} else {
switch (options) {
case "PATHINFO_DIRNAME": return path_obj.dirname;
case "PATHINFO_BASENAME": return path_obj.basename;
case "PATHINFO_EXTENSION": return path_obj.extension;
case "PATHINFO_FILENAME": return path_obj.filename;
}
}
}
example 1: pathinfo("/www/htdocs/index.html");
returns 1: {dirname:"/www/htdocs",basename:"index.html",extension:"html",filename:"index"}

b.substr(-suffix.length)
doesn't work in ie because him doesn't allow negative values as start index. To solve that the solution is:
b.substr(b.length-suffix.length)

The regular expression is not ECMAScript-262 compliant.
It should be:
var b = path.replace(/^.*[\/\\]/g, '');
ECMAScript does not allow / to appear anywhere in a regular expression literal unless it is escaped by the \ character.

I've fixed a couple of bugs in your current implementation: suffix should be optional, and basename should work for partial paths (e.g. basename("foo.txt" ".txt") should return "foo")
function basename(path, suffix) {
var b = path.replace(/^.*[/\\]/g, '');
if (typeof(suffix) == 'string' && b.substr(-suffix.length) == suffix) {
b = b.substr(0, b.length-suffix.length);

PICTURES: Soldiers in police gear attacked MDC supporters
Jonathan Moyo has claimed that MDC supporters were on Wednesday violently dispersed by a combined police, army and CIO team.
Posting on Twitter, Moyo said:
The Police Support Unit is currently conducting #CrowdControl training at 2 Brigade, Cranbone, bringing together the Army, Police & CIO. The vicious “cops” that unleashed yesterday’s gratuitous violence on MDC supporters, bystanders & passersbys came from the 2 Brigade Unit!
Moyo’s theory concurrs with that of Team Pachedu who suggested that the sjamboks which were used to beat protesters are used by soldiers and not the police.

Quartararo crashes, Marquez brothers fall in first day of MotoGP test
by Lewis DuncanFabio Quartararo topped the first 2020 pre-season MotoGP test in Valencia despite a crash, while new Honda line-up Marc and Alex Marquez wrecked their bikes in falls during the session.
Quartararo set a 1m30.163s late in the afternoon before bringing the session to a halt with a fall at Turn 10, but held onto top spot despite a challenge from Yamaha stablemate Maverick Vinales in the closing stages.
After an hour of the session, just four riders had completed a lap, with KTM's Pol Espargaro guiding this year's RC16 to a 1m31.447s ahead of Tech3 counterpart Iker Lecuona.
Honda rookie Alex Marquez - whose one-year deal to join the works team was confirmed on Monday - ventured out on track on Cal Crutchlow's '19-spec bike not long afterwards for his first laps on a MotoGP bike since the '14 Valencia test.
Just 20 minutes into his first run, Marquez crashed at the Turn 10 left-hander and badly damaged the bike.
At the same time, elder brother Marc took over from Espargaro with a 1m31.168s, which he improved to a 1m30.792s to end his first run on the '19 Honda just 0.002s clear of the field.
With nine minutes remaining of the second hour, the red flag briefly brought the session to a halt, as Aprilia test rider Bradley Smith crashed at Turn 10.
HRC test rider Stefan Bradl - who was first out on track on Tuesday morning - demolished the '20 prototype he was riding at the same corner some 40 minutes later.
Honda's day would get worse, as Marc Marquez wrecked his only '20 Honda in a crash at Turn 13 around an hour later on an out-lap - which caused another red flag and left him to complete the day on this year's bike.
When the session got back underway, Petronas SRT's Quartararo took over top spot with a 1m30.599s as he - as well as team-mate Franco Morbidelli - put miles on his current bike, albeit with slightly different aerodynamic packages and a carbon fibre swingarm.
Vinales deposed Quartararo at mid-afternoon with a 1m30.593s on the '20 M1, which featured a new chassis and engine. With 90 minutes left, Quartararo re-assumed top spot with a 1m30.163s, but would crash at Turn 10 moments later and bring out a third red flag.
Vinales cut his advantage down to 0.164s late on, but Quartararo would remain top, while Morbidelli completed an all-Yamaha top three on Tuesday.
Andrea Dovizioso was top Ducati in fourth, having spent the day evaluating a new chassis amongst other '20 parts. Team-mate Danilo Petrucci only completed 10 laps due to an ongoing shoulder injury and was 12th, while Jack Miller was 10th on a bike largely similar to the one he rode all season.
Marc Marquez was fifth in the end, with Suzuki duo Joan Mir and Alex Rins behind - both trialling a new chassis and the new engine which test rider Sylvain Guintoli first tried in Japan last month.
KTM's Espargaro was eighth, as he switched his focus to the '20 RC16, which sported a radically redesigned steel chassis.
He finished ahead of Valentino Rossi on the second works Yamaha. Lecuona was top rookie in 13th, with works KTM counterpart Brad Binder 21st and Alex Marquez 23rd after Honda managed to repair his bike from his earlier crash.

Verification – Software Bug Report
During the Gulf War in the early 1990’s, Operation Desert Storm used sophisticated technology to end the war in a quick and timely manner. Part of this technology was that of the Patriot missile air defence system.1
On the night of the 25th of February, 1991, a Patriot missile system operating in Dhahran, Saudi Arabia, failed to track and intercept an incoming Scud. The Iraqi missile impacted into an army barracks, killing 28 U.S. soldiers and injuring another 98.
The cause of the missile system failing to defend against the incoming Scud was traced back to a bug in Patriot’s radar and tracking software.2
The Patriot is a surface-to-air defence missile system manufactured by Raytheon3 and used by the United States Army, originally designed to protect against Soviet cruise missiles and medium to high altitude aircraft. In order to avoid detection it was mobile and would only operate for a few hours at a time.
During Operation Desert Shield (the operation to move forces to the Gulf region), Patriot battalions were deployed in strategic locations in Saudi Arabia and Israel to defend key assets, military personnel, and citizens against Scud missiles launched by Iraqi forces.
Each battalion usually comprised of six batteries, with each battery containing a number of components including a single ground based radar unit used for surveillance target detection and tracking, an Engagement Control Station to control missile interceptors, eight missile launchers, as well as various communications and relay components.4
The Patriot’s weapon control computer performs crucial system functions for tracking and intercepting targets, as well as other control tasks. The system tracked and intercepted missiles in a number of stages:
The bug occurs in the calculation of the next location of the incoming target by the range gate. The prediction is calculated based on the target’s velocity and the time of the last radar detection.
Velocity is stored as a whole number and a decimal, and time is a continuous integer or whole number (i.e. the longer the system has been running, the larger the value) measured in tenths of a second.
The algorithm used to predict the next air space to scan by the radar requires that both velocity and time be expressed as real numbers. However, the Patriot’s computer only has 24 bit fixed-point registers. Because time was measured as the number of tenth-seconds, the value 1/10, which has a non-terminating binary expansion, was chopped at 24 bits after the radix point.5 The error in precision grows as the time value increases, and the inaccuracy resulting from this is directly proportional to the target’s velocity.
When the Patriot system was first designed, the primary targets were Soviet aircraft and cruise missiles travelling at speeds around MACH 2, and only operating at a few hours at a time. However, in Operation Desert Storm, they were deployed as static defences (operating continuously), tracking and intercepting Scud missiles travelling at speeds of approximately MACH 5.6 Consequently, the U.S. army had to learn how to adapt the Patriot for targets of much higher velocity.
Ironically, Israeli forces had noticed the anomaly in the Patriot’s range gate’s predictions in early February 1991, and informed the U.S. Army of the problem. They told the Army that the Patriots suffered a 20% targeting inaccuracy after continuous operation for 8 hours.
Army officials presumed that Patriot users were not running the systems for longer than 8 hours at a time. They suggested if they would be running for continuous periods, they were rebooted regularly (which took around 1 minute and would reset the system clock to zero).
The Army however did set to work to produce a fix that would be distributed to all Patriot systems that would fix the problem.
On the 25th February 1991, Iraqi forces targeting an airfield in Dhahran, Saudi Arabia launched a Scud missile. Six Patriot batteries were assigned to protect the airfields and seaports of Dhahran; in particular, Alpha battery was the one assigned the targeted airfield.7
Alpha battery had been in continuous operation for over 100 consecutive hours, and the resulting inaccuracy resulting from the software bug was roughly 0.34 seconds. However, this meant that the range gate could not successfully track the incoming Scud (travelling at roughly 1.7km/sec, so the time difference resulted in the range gate scanning an area of air space more than half a kilometre away from the missile). See Appendix A and for more details.
No Patriot missiles were launched to intercept the incoming Scud, which successfully hit a warehouse being used by the U.S. Army as a barracks, killing 28 soldiers, and another 98 people were injured.
When Patriot systems were brought into the Gulf conflict, the software was modified (several times) to cope with the high speed of ballistic missiles, for which the system was not originally designed.
The modification to fix this bug was to introduce call subroutine that would do a more accurate integer to real conversion of the time value. This subroutine was inserted roughly half a dozen times in various locations in the Patriot software.8
The modified software was released on 16 February 1991, however did not reach Dhahran till the 26 February 1991, the day after the incident occurred. According to Army officials, the delay was caused by the time it took to arrange for transportation of the software to wartime locations.(4)
Various reviews and reports on Patriot missile performance were conducted throughout the 1990’s, and the Dhahran incident shows the necessity of well-documented requirements, software testing and correctness.

Last weekend, I updated PinPress – my command-line-based utility to create text templates of Pinboard data – with a (I think) much-needed feature: URL linking.
Here’s the use case: you’re humming along, saving interesting links to your Pinboard, and you want to store linkable URLs in the description of a pin1. Moreover, you want to be able to use those links in your PinPress output: if a description includes a URL, it out to come out of a PinPress as a hyperlink.
TL;DR
PinPress now includes the ability to create hyperlinks around URLs in Pinboard data.
The Background
It seems simple enough, especially given Pinboard’s FAQ on the matter:
The only HTML element allowed in descriptions is
, useful for displaying cited text. Any URLs in description text will be auto-hyperlinked.
Here’s the problem: although the auto-hyperlinking happens on the Pinboard website:
…nothing comparable happens to the data when returned from PinPress:
Bummer.2 It got me thinking: is there a nice way to automate the creation of hyperlinks around URLs when PinPress exports its data?
The New Stuff
With version 1.6.1, PinPress now has the ability to do just that. Best of all, it can accommodate two different scenarios:
- Auto Linking (wherein the URL gets wrapped in a hyperlink that uses the URL itself as the text)
- Manual Linking (wherein the URL gets wrapped in a hyperlink that uses user-defined text)
More is explained below, but make sure to check out the GitHub repository for more in-depth documentation.
Auto Linking
Auto Linking gets activated in one of two ways: either you specify the -a
switch when running pinpress pins
or you include auto_link: true
in the pinpress
section of the configuration file (located at ~/.pinpress
).
Let’s try the “switch route” and run:
$ pinpress pins -n 1 -a
This produces output wherein every URL found is automatically wrapped in a hyperlink. So, for example, if PinPress finds this URL in a pin description:
http://www.google.com
…it gets turned into this:
http://www.google.com
Neat!
Manual Linking
But what if you want to customize the text of the hyperlink? That’s where Manual Linking comes into play. Like Auto Linking, it can be activated via a switch or a configuration key/value (-l
and manual_link: true
, respectively).
Again, an example:
$ pinpress pins -n 1 -m
This produces a prompt for every URL, giving the user a chance to specify what the link text should be:
—> URL FOUND!
URL: http://www.google.com
TITLE: I Want to Pin Google on Pinboard
POSITION: …http://www.google.com…
What do you want the link text to say?:
Note that in addition to the URL, the user is given the title of the pin in which the URL was found and its rough “position” (i.e., where it occurs in the description compared to surrounding text).
If I type in “Le Googlez” and hit return, the URL gets output like this:
Le Googlez
Neat again!
Saved Configurations
With both Auto and Manual Linking, PinPress saves the link information into the configuration file; under the links
heading, you’ll see entries that look like this:
4a0f001e05877a9473b7dd8d3b2c70cf:
title: I Want to Pin Google on Pinboard
url: http://www.google.com
link_text: Le Googlez
This happens for two reasons:
- By saving this configuration info, PinPress ensures that it doesn’t (a) have to recalculate hyperlinks (in the case of Auto Linking) and (b) re-prompt the user (in the case of Manual Linking) when it finds URLs in pins that it’s already run across.
- Going forward, if the user wants to change the URL text, they can do it easily.
Onward
PinPress is one of my favorite projects; it serves a niche need, but is super fun to play with. If there are any features you’d like to request, please do so on the GitHub Issues Page!

20: Matching lines in files with grep
You will often want to search files to find lines that match a certain pattern. The Unix command grep does this (and much more).
First change directory to example_data
.
learner@:~$ cd example_data
The following examples show how you can use grep's command-line options to:
- show lines that match a specified pattern
learner@:example_data$ grep 'was' opening_lines.txt
The Galactic Empire was dying.

The SpryValidationRadio.css file provides the default styling for the Validation Radio Button widget. You can customize the widget by changing the appropriate CSS rule. The CSS rules in the SpryValidationRadio.css file use the same class names as the related elements in the widget’s HTML code, so it’s easy for you to know which CSS rules correspond to the widget and its error states.
The SpryValidationRadio.css file should already be included in your website before you start customizing. For more information, see Prepare your files.
The SpryValidationRadio.css file contains extensive comments, explaining the code and the purpose for certain rules. For further information, see the comments in the file.
By default, error messages for the Validation Radio Button widget appear in red with a 1-pixel solid border surrounding the text.

Although you can replace error message-related class names with class names of your own by changing the rules in the CSS and the class names in the HTML code, you cannot change or replace state-related class names, because the behaviors are hard coded as part of the Spry framework. You can, however, override the default state-related class name with your own class name by specifying a new value in the third parameter of the widget constructor.
<script type="text/javascript"> var spryRadio1 = new Spry.Widget.ValidationRadio("RadioWidget", {requiredClass:"required"}); </script>
The following table provides a list of options you can use to override built-in state-related class names.

Description |
|---|---|
|
requiredClass |
Overrides the "radioRequiredState" built-in value. |
|
invalidClass |
Overrides the "radioInvalidState" built-in value. |

An Outputter is a logging destination with a particular way to format data. It has a level threshold and a flexible level mask.
Outputters must have names.
Outputters have their own level thresholds that default to root level. They will not write any log events with a rank less than their threshold.
Alternatively, an Outputter can be told to log specific levels only:
o = StdoutOutputter.new 'console' o.only_at DEBUG, FATAL # only DEBUG and FATAL get written
When outputters are created, they store themselves in an Outputter repository similar to the Logger repository.
StdoutOutputter.new 'console' => Create 'console' outputter Outputter['console'] => Get it back from the stash.
An outputter has a format defined by its Formatter. If no Formatter is specified, DefaultFormatter will be used.
The basic Outputter class is both abstract and a null object.
log4r/outputter/syslogoutputter.rb - Logs to syslog
log4r/outputter/emailoutputter.rb - Email logs
log4r/logserver.rb - For remote logging
Log4r::IOOutputter - for any IO object
Log4r::StdoutOutputter - $stdout
Log4r::StderrOutputter - $stderr
Log4r::FileOutputter - log to a file
Log4r::RollingFileOutputter - log to a file and split it as it grows
Log4r::SyslogOutputter - logs to syslog
Log4r::EmailOutputter - email logs
Log4r::RemoteOutputter - for remote logging
Two outputters named ‘stdout’ and ‘stderr’ are created automatically at the root level. They are nice shortcuts.
Outputter['stdout'] => 'stdout' Outputter['stderr'] => 'stderr' Outputter.stdout => 'stdout' Outputter.stderr => 'stderr'
Outputters must have names and receive hash arguments. The parameter name for the hash args can be either a symbol or a string. All defined outputters accept :level and :formatter arguments. For arguments specific to a convenience Outputter, please look at the class description.
The level threshold, the levels to log at (only_at) and formatter can be changed dynamically using the = methods.
As a collective example of all this, here are various ways to set up an IOOutputter:
IOOutputter.new ExoticIO.new 'exotic', 'level' => WARN, :formatter => MyFormatter.new # an equivalent way: o = IOOutputter.new ExoticIO.new 'exotic' o.level = WARN o.formatter = MyFormatter # we can specify just the class o.only_at = THIS, THAT
Specify outputters as children of <log4r_config>:
<log4r_config> <outputter name="myout" type="Log4r::StdoutOutputter"> <only_at>DEBUG, INFO</only_at> </outputter> <outputter name="file" level="WARN"> <type>FileOutputter</type> <filename>#{logpath}/file.log</filename> <trunc>false</trunc> </outputter> ...
As explained in log4r/configurator.rb, the hash arguments you would normally pass to new are specified as XML parameters. It is given an IO object to write to, a Formatter to call, and, optionally, levels to write at.
Outputters invoke print then flush on the wrapped IO object. If the IO chokes, the Outputter will close the IO and set its level to OFF.

Finding an internship is never easy, especially when you are new to the field and have little experience. This post will give you tips and advices to look for an internship no matter your school year.
Companies don't like risks. That's why they want to hire experienced students or students in their 3rd or 4th year with the hope they will come back to work for the same company after graduating. However, lots of companies also love hiring smart, innovative individuals who will make an impact. This is what you need to prove! But how do you do it?
1. Side Projects
This is pretty much said by everyone already because it is the truth. Don't overthink your projects. Try to follow any tutorials you can find. If you overthink your projects, you might end up having a great idea but often time you waste a lot of time trying to just come up with the idea. You can make an Instagram clone, spin it in a cool way after. At that point, you have something to talk about when you meet a recruiter, for example, at an internship fair. Your projects also fill up the blank space of someone's resumes that don't have a lot of professional experience.
Doing side projects is also a great way to fill up the skills section in your resume. If you Hadley applied to multiple companies before, you would have seen each company works with a different technology. It is advantageous to have as many skills as possible. However, make sure you actually have some experience with them, not just a little. It would look not so good when you're in an interview and the interviewer asks you about a skill you cannot even talk about at length.
2. Participating in Hackathons
Many companies love hackathons. The pros of going to hackathons are: meeting companies' representatives; meeting other CS students; potentially making a cool project; potentially winning something. Having one or more hackathon awards on your resume will definitely catch the eyes of recruiters. Those awards show that you can work well in team; you are really innovative; and you are passionate about coding.
3. Getting an interview
Many people struggle with just getting an interview. It is quite difficult because lots of companies will just filter out your resume if it does not have the school year the companies look for. However, do not lose hope. It is important to convince the companies that you have the experience and skills that many junior and above students don't have. How do you do it? Something that works for me is after each application, I find the company's recruiter or talent acquisitioner on a platform like LinkedIn.com. A free option without having a LinkedIn Premium subscription is to send a connect request with a note. The note section is 300-character capped so it must have only your name, school, skills, achievements, projects. This method personally got me a good amount of interviews.
Before Covid-19, internship fair is a great way to get noticed by companies. Typically colleges will host internship fairs once or twice a year. Companies spend their time and resource there for a reason: they want some interns. It is now your job to make both your and their life easier by convincing them that you're a potential candidate for the job. If you attend an intern fair, try to go talk to as many company representatives as possible: give a quick elevator speech about yourself and why you're a suitable candidate for the position; talk and get to know the company; and get someone's contact from the company, preferably a recruiter's. This is the most you can do to get yourself interviewed by the company.
4. Preparing for an interview
There are mainly two types of interviews that you'll encounter in the search for an internship: a technical interview and a behavioral interview.
For the technical interview, it is favorable to solve the questions successfully, passing all test cases. It is one of the most difficult tasks because these questions are not easy. To hopefully do well on any questions: it is recommended that you practice as many questions as possible. The main source of practice for most in this field will be LeetCode.
The behavioral interview won't be as bad. Just be honest and sincere about your responses. This interview is to see your personality, especially whether you are equipped to work in a team and whether you would be a good worker.
Good luck to everyone out there who is trying to find an internship. I hope this little post will be useful for you.

Noble.Animation
Animation states using a spritesheet/imagetable.
Ideal for use with playdate.graphics.sprite
objects, but suitable for other uses as well.
Setup
- Noble.Animation.new(__spritesheet)
-
Create a new animation "state machine".
Parameters
- __spritesheet
string
The path to the bitmap spritesheet/imagetable asset. See Playdate SDK docs for imagetable file naming conventions.
Returns
animation
, a new animation object.Usage
MyHero = {} class("MyHero").extends(Graphics.sprite) function MyHero:init() MyHero.super.init(self) -- ... self.animation = Noble.Animation.new("assets/images/Hero") self.animation:addState("idle", 1, 30) self.animation:addState("jump", 31, 34, "float") self.animation:addState("float", 35, 45) self.animation:addState("turn", 46, 55, "idle") self.animation:addState("walk", 56, 65) -- ... end
- __spritesheet
string
- animation:addState(__name, __startFrame, __endFrame, __next[, __loop=true], __onComplete)
-
Add an animation state. The first state added will be the default set for this animation.
NOTE: Added states are first-degree member objects of your Noble.Animation object, so do not use names of already existing methods/properties ("current", "draw", etc.).
Parameters
- __name
string
The name of the animation, this is also used as the key for the animation. - __startFrame
int
This is the first frame for this animation in the imagetable/spritesheet - __endFrame
int
This is the first frame for this animation in the imagetable/spritesheet - __next
string
By default, animation states will loop, but if you want to sequence an animation, enter the name of the next state here. - __loop
bool
= true (default)
If you want a state to "freeze" on its final frame, instead of looping, enterfalse
here. - __onComplete
This function will run when this animation is complete. Be careful when using this on a looping animation!
Usage
-- You can reference an animation's state's properties using bog-standard lua syntax: animation.idle.endFrame -- 30 animation.walk.endFrame -- 65 animation.["walk"].endFrame -- 65 animation.jump.name -- "jump" animation.["jump"].next -- "float" animation.idle.next -- nil
- __name
string
Properties
- animation.current
-
The currently set animation state.
This is intended as
read-only
. You should not modify this property directly.See
- animation.currentName
-
The name of the current animation state. Calling this instead of
animation.current.name
is just a little faster.This is intended as
read-only
. You should not modify this property directly. - animation.currentFrame
-
The current frame of the animation. This is the index of the imagetable, not the frame of the current state.
Most of the time, you should not modify this directly, although you can if you're feeling saucy and are prepared for unpredictable results.
See
- animation.direction
-
This controls the flipping of the image when drawing. DIRECTION_RIGHT is unflipped, DIRECTION_LEFT is flipped on the X axis.
Usage
function MyHero:goLeft() self.animation.direction = Noble.Animation.DIRECTION_LEFT -- ... end
- animation.imageTable
-
This animation's spritesheet. You can replace this with another
playdate.graphics.imagetable
object, but generally you would not want to.See
Methods
- animation:setState(__animationState[, __continuous=false], __unlessThisState)
-
Sets the current animation state. This can be run in a object's
update
method because it only changes the animation state if the new state is different from the current one.Parameters
- __animationState
string or Noble.Animation
The name of the animation to set. You can pass the name of the state, or the object itself. - __continuous
bool
= false (default)
Set to true if your new state's frames line up with the previous one's, i.e.: two walk cycles but one is wearing a cute hat! - __unlessThisState
string or Noble.Animation
If this state is the current state, do not set the new one.
Usage
animation:setState("walk")
animation:setState(animation.walk)
animation:setState(animation.walkNoHat) -- animation:setState(animation.walkYesHat, true)
function MyHero:update() -- Input -- ... -- Physics/collisions -- ... -- Animation states if (grounded) then if (turning) then self.animation:setState(self.animation.turn) elseif (math.abs(self.velocity.x) > 15) then self.animation:setState(self.animation.walk, false, self.animation.turn) else self.animation:setState(self.animation.idle, false, self.animation.turn) end else self.animation:setState(self.animation.jump, false, self.animation.float) end groundedLastFrame = grounded end
- __animationState
string or Noble.Animation
- animation:draw([__x=0[, __y=0[, __advance=true]]])
-
Draw the current frame.
The ideal place for this is in a
playdate.graphics.sprite:draw()
for characters and items, or NobleScene:update for basic graphical scene objects.Parameters
- __x
number
= 0 (default)
- __y
number
= 0 (default)
- __advance
bool
= true (default)
Advances to the next frame after drawing this one.
Usage
function MySprite:draw() animation:draw() end
function MyScene:update() animation:draw(100,100) end
- __x
number
= 0 (default)
- animation:drawFrame(__frameNumber[, __stateName=self.currentName[, __x=0[, __y=0[, __direction=self.direction]]]])
-
Sometimes, you just want to draw a specific frame.
Use this for objects or sprites that you want to control outside of update loops, such as score counters, flipbook-style objects that respond to player input, etc.
Parameters
- __frameNumber
int
The frame to draw from the current state. This is not an imagetable index. Entering1
will draw the selected state'sstartFrame
. - __stateName
string
= self.currentName (default)
The specific state to pull the __frameNumber from. - __x
number
= 0 (default)
- __y
number
= 0 (default)
- __direction
= self.direction (default)
Override the current direction.
- __frameNumber
int

He be the count of Monte Cristo,
could be a quake any day
Maybe somebody from Siam,
begin the era of a new rage
Keeps lickin� all the honey,
chewin� up the fat he rakes
Instead of sending to the lions,
they cover him with praise
All hail caesar hail! Hail!
All hail caesar hail! Hail!
Down at the epicentre
things started heatin� up
Rockin� up the Richter scale
Swingin� in the chariot
around and around we go
The senators rehearse the tale
Starring in the coliseum,
tied upon the rack
Up comes the thumb of Caesar
to stab you in the back
All hail caesar hail! Hail!
All hail caesar hail! Hail!
Down at the epicenter
things started heatin� up
Rockin� on the Richter scale
Swingin� in the chariot
around and around we go
The senators rehearse the tale
Watch out Caesar
Watch out Caesar
I said hail
All hail caesar hail! Hail!
All hail caesar hail! Hail!
