Thanks Jon for answering this:

A while ago, Alan Cox write a G+ post pointing me to Easy 6502 by skilldrick. The last couple of weeks I finally found time to play with it:
It is a tutorial ebook by Nick Morgan with examples and a play ground based on the adapted JavaScript 6502 assembler and simulator right integrated into a github.io site.
From the perspective of learning assembly language to get a grasp of thinking at the lowest computer abstraction, it is an ideal tutorial: the 6502 is a very simple 8-bit processor with only 3 registers. These restrictions make programming fun.
These are the topics covered:
This is what Alan thinks about it:
… some of the other 6502 tutorials
This one is really really neat – bit more basic than the bits I need to brush up on but really nicely done.

Brilliant! Cast to xml, if it is nil, then the second cast to bool will give false, otherwise true:
Thanks Shay Levy!

Thanks [Wayback] Jørn Einar Angeltveit for sharing this a while ago:
A session by Jon Skeet and Tony the Pony (which has strong teeth) presented during the Polish DevDay 2013 in Kraków, Poland.
[Wayback] +Jon Skeet’s speech [Wayback] “Back to basics” is really a good watch.
In a funny way, he explains why the simplest fundamentals of computer software text, dates and numbers can cause some real headache for the programmer…
In case you didn’t know: Jon Skeet is “Chuck Norris” on [Wayback] stackoverflow.com:
The subtitle is “the mess we’ve made of our fundamental data types”.

Nice question (thanks aplm!), as for instance Gist does not render html:
Pastebin is a useful online tool to paste snippets of text. Pastie is a similar tool. Also, Ideone is similar except that it also runs the source code, as well as being a general pastebin.
Is there a similar tool, for HTML?
And ditto links in the answer (thanks meder!):
Unbelievable that such questions get closed as “not constructive”.
Note I could not get http://www.pastekit.com to work.

Now that DynamicDNS moved itself to a fully payed service, named it DynDns Pro, then renamed it Remote Access and limiting it to 30 hosts for USD 25 a year, I looked for alternatives, and noticed NO-IP.
I like it for a few reasons:
OK, last year, there was this Microsoft Legal Action and Controversy, but I think that is a once time thing (some people even argue that Microsoft wasn’t thinking), so I created the last script below in PowerShell.
A few open-source scripts to keep your NO-IP account happy (that also work on most other DDNS providers like Duck DNS):

A long and shorter while ago, I wrote about practicing your coding and test driven development skills:
Here are some Coding Kata videos of the Bowling Game Kata in various languages and environments. Some of them are dumb (no audio) just like good practice usually is. Note: it helps to know a bit about 10 Pin Bowling Scoring rules.
And since I want to learn Haskell and have done a lot of Tic-Tac-Toe demos inthe past:

If you are running OpenSSL as a regular user, or cannot perform “RunAs Administrator”, and you get this error message:
unable to write 'random state'
then make sure you have set your environment variables correctly before running OpenSSL:
RANDFILE=%LOCALAPPDATA%\.rnd
A full batch file front-end for OpenSSL.exe is this one:

Mac OS X has md5, but no md5sum.
I agree with Mac OS X: Replicating md5sum Output Format that the second way of emulating md5 is better than the first one.
So here it is:
| #!/bin/bash | |
| /sbin/md5 -r "$@" |

Wow: I feel like having lived under a stone for 8 years, as RosettaCode has been alive since it was founded in 2007 by Mike Mol.
The idea is that you solve a task and learn from that, or learn by seeing how others have solved tasks or draft tasks.
So in a sense it is similar to the Rosetta stone: it has different languages phrasing the same tasks.
There are already a whole bunch of languages on RosettaCode (of which a few are in the categories below), and you can even suggest or add your own languages.
When you want to solve tasks, be sure to look at the list unimplemented tasks by language that leads to automatic reports by language (for instance two of the languages I use most often: C# and Delphi).
I’m sure there are lots of programming chrestomathy sites, even beyond the ones, and it feels very similar to programming kata sites.
