הדבר הבא לעשות היה לבדוק למה, ומסתבר שרוב התנועה באתר שלי בחודשים האחרונים היתה מחיפושי גוגל שהובילו למאמרים על Ubuntu, ובהחלט נראה שהתנועה על המאמרים האלה יבשה: בכל יולי היו פחות מ-500 כניסות לכל מאמר.

זה בהחלט סביר, מכיוון שהמאמרים האלה היו על בעיות די זמניות במערכת ההפעלה, אבל בכל זאת – חבל: לקצת זמן היה נראה שלי שהבלוג שלי אינו זוטה

It was obviously way to geeky for the task at hand, so here it is now for you to answer – or better yet: invent your a worst geeky personality question:

If you’d have been a design pattern (or an anti-pattern), which design pattern you’d be and why?

I, for laughs, I’d say I would have been a Duff’s device – complicated and impossible to debug

Its the first annual catholic conference on “Geocentrism”, where you’d find interesting lectures such as “Scientific experiments showing the earth motionless in space” and “Geocentrism: they know it by they’re hiding it”.

Brilliant, and just when you though its safe to walk outside.

Thanks to Skepticality, some brave fools are going to go there, possibly armed with t-shirts proclaiming their heliocentric beliefs. I probably would have put out something like “Galileo was right but all I got was this lousy t-shirt”. Or something.

This is in Internet Explorer 8 when set to IE7 mode, but this is very faithful to the original as I’ve tested it on a real IE7 and it behaves the same. What happens here is that when you scroll the page down, all absolutely positioned elements (the two “combo boxes” which are a custom UI widget and the text “Dimensions:… at the top right corner”) get pulled down a few pixels. When you scroll up, they get put back in the correct place.

I would (maybe) understand if that would have happened only for the custom UI widgets (as there is a lot of Javascript code in place to support these, and I would understand if it behaves funny on broken browsers), but it affects the absolutely positioned text exactly the same, and there is nothing funky with that – its simply a block of text that is absolutely positioned.

On a slightly different subject, here is a useful tip for doing using Javascript to manipulate elements in IE7: if you have some Javascript that acts immediately after the page loads and put more content on the page and moves some elements around, if any of these elements are absolutely positioned then IE7 will ignore any changes to their layout, such as setting margins (especially negative margins) and such. This happens if you both change the element’s layout implictly (by adding content, for example) and explicitly (by setting style attributes) in the same Javascript call – the style attributes are ignored.

What you should do is to change the content in one Javascript call, then let the layout settle by exiting back to the rendering engine and then coming back to Javascript to change the layout. I do it like this:


$('block').innerHTML = 'Some text that should be updated';
window.setTimeout(function() {
$('block').style.marginTop = '-20px';
},0);


The window.setTimeout() with a zero miliseconds timeout will cause the code to stop executing without doing the style manipulation, the Javascript machine hands the execution back to the browser which then lets the rendering engine repaint the screen with the updated content – the problem with IE7 is that the rendering engine fails to take into account style changes that were made after content changes were done in the same Javascript execution, so we don’t do that. As soon as the rendering engine is done – less then one milisecond later – the timeout kicks in and adjusts the style, and finally handing the execution back to the rendering engine to adjust that as well.

Yep, that sounds about right.

What is interesting (to me anyway), is that the game is full encoded using HTML and Javascript – each ghost or pacman and also all the dots are graphics assigned using CSS to HTML DIV elements, which are moved on the screen using Javascript (source code is here at the moment – it is minified but its not hard to figure out what is going on).

[Update:]

As per the schedule, the pac-man game was removed after about 48 hours.

Yes, this device runs better with all kinds of logo MS-Windows operating systems: you can choose either XP, 7 or Linux

The sprite collision detection is not brilliant, but you can burninate villagers!
