User:Badon



I do mostly testing, bug hunting, and documentation writing. I have a particular interest in doing it for Semantic MediaWiki and related extensions, but I jump in anywhere I feel I can be helpful. I usually avoid documentation writing for SMW and related extensions, except on my user page here, where I like to add useful bits of info I want to share.

I have officially reported 75 bugs as of January 1, 2012 (and a few more unofficially *). 56 of them are either FIXED or still open, and the rest are DUPLICATE, WONTFIX, or LATER. That gives me a 75% "usefulness" rate in my bug reports, with the remaining 25% often resulting in improved documentation (when the bug is actually an undocumented feature). I am always trying to improve my bug hunting skills and methods.

Twiddla widget
Extension:Widgets is a very powerful extension that's simple to use, and thoroughly replaces the obsolete Extension:RawMsg. Here's a Twiddla widget I made that you can use on your own wiki with the Widgets extension installed. It is very useful when you want to show someone how to do something on your wiki.

This widget allows you to add a Twiddla meeting to a page. [ Edit the page] to see the widget text.

You may use the widget like this:



Bug hunting tips


This section may evolve into a full guide for debugging. For now, he's a few tips:


 * Check to make sure you haven't accidentally pasted the wrong text into a page. Semantic Forms pages and template pages getting swapped can produce errors that take down the wiki (until the code prevents those error conditions).
 * Check your clipboard manager's hotkey settings (if you have one) to make sure that you're not accidentally triggering hotkey functions that can be screwing up your pastes.
 * Use code inspectors like FireFox FireBug, Opera Dragonfly, or Chrome Inspector, to look at what HTML, CSS, JS, etc is being generated on a wiki page that isn't behaving like you think it should.
 * Use some code to automatically show an error message if you paste code into the wrong page by accident, like this (with Parser functions):


 * Strip down the problem code or circumstance until the bug goes away. That will be your bug demo.
 * If you're struggling with isolating the bug, try setting up a fresh MediaWiki install with the bare minimum of extensions and other "accessories" so you can reproduce the bug with minimum confusion.
 * Try running your test MediaWiki on a separate host from your usual host, so you can eliminate the possibility of a hosting quirk as being the source of your bug. I recommend No Support Linux Hosting for a really cheap hosting solution that makes it easy to set up as many as you want, as long as you're skilled enough to not need support for setting up a website.
 * Make sure common data corruption is not the problem by doing your production hosting on a ZFS system. I think nearly all mysterious failures that can't be traced to a bug are caused by normal data corruption. Data corruption is something that I hope is one day not considered normal anymore. No Support Linux Hosting virtualizes their Linux systems on top of a ZFS storage backbone, so you can use ZFS with Linux even though Linux doesn't support ZFS yet. Another recommendation for ZFS hosting is Entic.net, with very good support and Cartika, which I haven't used yet, but I would like to. All of my recommended hosts will not cause "bugs" to suddenly appear due to data corruption. You can also set up your own ZFS hosting with FreeBSD, which has software support that's almost as good as Linux, and ZFS support that's almost as good as Solaris.
 * Finally, if you're sure you've found a bug, report it.

Advanced MediaWiki programming tips

 * Whitespace is the enemy.
 * If you can't get rid of the whitespace that's screwing up your wiki pages (especially in tables), put this in your MediaWiki:Common.css to make most of the annoying whitespace "disappear":

.wikitable p { margin:0; padding:0; }


 * Since MediaWiki and web browsers do not show all whitespace characters, finding extra whitespace can be done with the urlencode magic word.
 * Use HTML lists and tables instead of wiki lists and tables. It makes formatting much easier, and less fragile.
 * Use at the end of lines to prevent the buildup of empty wiki paragraphs (1 for each 2 newlines), like this:


 * Do not use inside #vardefine if you are going to test it with an #if, because in your variables will cause them to always pass the test. Like this:


 * is not needed inside functions that do not directly or indirectly output anything, like in string manipulation code.
 * It is better to use many #vardefines within nested #if tests than to place your #if statements inside a #vardefine. It makes debugging mysterious whitespace much easier. Like this:

The ultimate solution to every difficult problem
If you're having no success in solving a difficult problem, you can keep pathetically hacking away at it, or you can put down your psychological torture devices and help someone else solve their problems. Every time I get stuck on something because:


 * I don't have enough skills.
 * I don't have enough experience.
 * I don't have enough knowledge.
 * I've spent too much time coding and my brain is fried.
 * All of the above.

I always find the solution after spending time helping other people solve their problems. Why? Well, for starters, even if I know exactly how to solve the problem, I usually still need to freshen my knowledge by re-reading documentation and doing some easy searches. After a few minutes to a few days of answering questions on the mailing lists, forums, talk pages, and IRC, most of the time I have read and written enough documentation (the answer to someone's question) to stumble upon a fresh idea for solving my own issues.

Whenever I can't sleep at night because some problem is challenging me, I find peace and inspiration by helping others. That works for me, and maybe it will work for you too.

Giving gifts


If you are an awesome MediaWiki helper, please put your Amazon wishlist on your user page. Note that you will not be able to stay anonymous if you do that. If you want to remain anonymous, "printable" eBay gift certificate codes can be emailed to you. If you're a recipient of help from an awesome MediWiki helper, here's where you go to get an eBay gift certificate code to show your appreciation:

https://www.paypal.com/cgi-bin/webscr?cmd=_ebay-gift-certificate

Be sure to select the option:


 * I will print out the gift certificate and deliver it myself.

And then select the amount you want to give. Don't enter in anything else.

Buying stuff for people on their Amazon wishlist, and sending "printable" eBay gift certificate codes, are both anonymous for the sender too! I recommend that you stay anonymous when sending people gifts for several reasons:


 * 1) Everyone loves a mystery.
 * 2) It does not create any expectations of future gift-giving.
 * 3) It encourages everyone to be polite and helpful to each other, since there's no way to know who's sending the gifts and who isn't.

That last one is the most important. Even if only 2 or 3 people are sending gifts, as long as they do it anonymously, it makes the MediaWiki community much more friendly for every one of the thousands of people involved.
