Just got bitten by Wrong time zone using Chrome on Mac:
Chrome does not pick up on time zone changes until a new tab is opened or the browser restarted.
Actually, it requires a browser restart, as below is the difference between a new Chrome tab and running on jsc on the console: Read the rest of this entry »

Now I have these aliases in my ~/.bash_profile:
alias jsc='/System/Library/Frameworks/JavaScriptCore.framework/Versions/Current/Resources/jsc'
alias JavaScript='/System/Library/Frameworks/JavaScriptCore.framework/Versions/Current/Resources/jsc'
Now I can use the WebKit jsc from the console.

With a more decent internet connection during our trip, it is time to catch up on some recent news.
The first that caught my eye was that the Chromecast API now is open to all developers.
Developer information is available through Casting Your Content to the Big Screen – Google Cast — Google Developers.
You need to pay a one-time USD 5 fee per development account (how’s that Apple?) for the Google Cast SDK Developer Console.
After that, you will have to register your Chromecast device(s) and custom or styled media receiver apps.
Interesting. Fun.
I hope this can be combined with the new Smart Mobile Studio 2.0 release or the Delphi for Android support.
Will get back on that as soon as I’m back home.

This is brilliant for learning *nix shell programming:
explainshell.com – match command-line arguments to their help text
explainshell is a tool (with a web interface) capable of parsing man pages, extracting options and explain a given command-line by matching each argument to the relevant help text in the man page.
It has open source code at gitub too: idank/explainshell.

Lately I moved more and more away from wget, mainly because out of the box, wget (and also aria2, which I like for the bittorrent support) handle https downloads so badly: you need to manually setup your CA store on each and every installed system.
Not so with cURL, especially not on Windows any more, as “recently” (that is: since the last time I examined it, which is over a year ago now), there is a new kid in town: cURL for Windows: a Windows Installer for the Web Transfer Tool.
You don’t even need to download the installer. Grabbing the stuff from the bin directory in the zip download is enough: it contains a prepackaged CA certificate set that works splendid.
So now downloading https://dl.google.com/update2/installers/ChromeStandaloneSetup.exe to the current directory is as simple as Read the rest of this entry »

Just found out about the repl.it site that allows you to do a Read-Eval-Print-Loop with 15 different languages running from within your browser.
Really: from within your browser. Your browser becomes a console “IDE” by first translating the language to JavaScript then executing it on the browser.
They have all their code in a Git repository, with at the root implementations of those languages.
There are only a few pages on the site to complement the “IDE”:
According to their @replit twitter feed they have been around since about September 2011, but there are still regular updates.

About a year and a half ago, I wrote about a Batch file to “Keep Alive” a CMAK generated VPN connection in Windows 7.
It uses ping to wait a certain amount of time, but it has the drawbacks of
Since then, I learned that since Windows Vista and up has timeout command that just waits:
timeout /t 600 /nobreak
Two parameters are used:
(the example is 10 minutes, I use it to regularly run FlushFileCache.exe or FlushMem.exe to empty the Windows file chache and release memory – often more than a gigabyte – back to Windows)
There is also sleep.exe, but that requires the Windows Resource Kit or Windows Server 2000/2003.

One of the easy things in *nix is to set the value of an environment with the output of a command.
Something like this is possible in Windows too, but you have to instruct Windows to keep an empty set of delimiters to capture the full first line.
There is also a small but important difference between Windows and *nix upon command failure: *nix will always return an empty value, but in Windows you must make sure to empty the value first.

Wow, I’ve been living under a stone (:
Just discovered the online Cyber-Dojo by Jon Jagger. It is an online manifestation of a Coding Dojo. Both have been there for years, and I think both are brilliant.
They take the concept of a Dojo as being a place to practice sports like martial arts in a pair or group setting with a series of Katas or practices.
Katas in a Dojo are a means for performing deliberate practice in order to learn new things. For instance, acquire new movement techniques, learn about your balance, gain strength, all in both a physical and mental way.
A Coding Dojo takes this concept into the programming world focussing at learning new programming skills. Watch the How do you put on a coding dojo event? – YouTube
The Cyber Dojo goes a step further and brings it on-line (a 2010 example video is Roman Numerals Coding Kata in Ruby using CyberDojo website on Vimeo).It is easy to get started: either join an existing Dojo by entering the practice ID, or setup a new Dojo where you get a practice ID that others can join.
The aim of both is do more deliberate practice.
When performing Coding and Cyber Dojo, you should use Test Driven Development using pair programming and BabySteps. Those help you to slow down, as one of the Dojo Principles is for Katas to slow down. It reminds me of the “if you are in a hurry, sit down” mantra and is a key part of the Coding/Cyber Dojo Principles too.
The aim is to learn, and part of that is to first un-learn and open you to new thoughts. That’s why it is so cool that the Cyber-Dojo provides you with:
You’d think they speed you up, but that is not their aim. Like a regular Dojo it gives you an pre-set environment and gives you piece of mind to get started.
The Cyber Dojo does without a Sensei, whose purpose in a Coding Dojo is to ask questions in order to guide the participants.
That’s why it is good to use the Cyber Dojo as part of a Coding Dojo: basically the Cyber Dojo provides a standardizes set of tools to quickly setup a Coding Dojo.

Toon Krijthe posted an interesting question to SO.
Though 5 years old, I think it stilll is very valid one:
At my work, we have decided to stay with the ANSI characters for identifiers. Is there anybody out there using unicode identifiers and what are the experiences?
For all projects I work on (in various Languages like English, German, Dutch or other), I stick to ASCII characters (not even ANSI) for:
I also try to abstract the non-ASCII strings into places where I am sure that the encoding is preserved (for text files, I prefer UTF-8), or where these characters are properly escaped.
What is your take on this?
