Weird. The closest I've seen to that was when I moved a ZIP file, and it renamed itself to ‘02a02812’.

It was part of a fairly amusing fiasco about half a decade ago, which I recorded for someone...

There's loading speed, and there's transfer speed. A basic packer, just renaming identifiers and stripping whitespace and comments, can increase transfer speed (by making the file smaller) and also...

That's not necessarily true. A lot of packers use eval(), which will actually considerably slow the loading process overall, since it's still loading the full-sized script, but with an extra...

rm won't work with a folder; it's for files. You probably want rm -rf.

There's not much else to say about it, really :)

PHP does the two-pass parse model, to check for functions and load them before actually executing the script. Anything except a basic function definition (includes, conditional definitions, &c.)...

<input type="text"
onkeypress="
return '01'
.split()
.indexOf(String.fromCharCode(event.which || event.keyCode))
>= 0;
">

I can't say I like it. Taken individually the pieces look nice, but they don't fit together (the taskbar with the dock, for example). Also, that big ugly Comic Sans speech balloon is just hideous. ...

Scuba-diving in the Nile?

Not necessarily... percentages are fine for textual elements as well (although it's often a good idea to set a minimum width in ems in that case).

As Snookerman says, though, the majority of the...

Lookin' good! :)

Yes, I've always preferred hardware volume. It's much more convenient.

SELECT SUM(points) AS total_points FROM your_table WHERE user_id = '$user_id'

And for cross-browser markup that's HTML, preferably 4.01 Strict, not XHTML. Also, don't use pixel sizes for positioning.

It's not stupid, but it's not immoral either. It's just a big MD5 dictionary. There's nothing wrong with it. It could even be used to generate some interesting statistics about MD5. With proper...

A single-character one, yes.

O(36^n) if there are no capitals — that is, the time taken will be proportionate to the number of possible characters to the power of the length of the password. On a (my) modern PC, calculating the...

Depends. If the hash isn't in the dictionary, it will never be cracked. If it is, then probably only an hour or two on a fast computer — depending on the size of the dictionary, of course. Length...

Um... what makes you think this is Javascript or at all applicable to HTML forms? It looks like some form of Pascal.

It's not a security risk; it's just invalid according to the standard. See RFC2616§14.30.

Don't. Just fix your code. register_globals is obsolete for a reason: it presents several security risks. it was advised never to rely upon it, even before it was deprecated. It really should...

Thus my claim that it probably differs from person to person :)

If you've got static HTML pages, the easiest way to do it is to enable MultiViews:


Options +MultiViewsThen, for an URL /dir/foo, Apache will try to load /dir/foo.html. You can also use this to...

In this case (comparing a known string with '') there isn't much difference (although it could well be more efficient) — it's just good practice.

That should be more or less fine, although from that snippet it looks like you're echoing markup from PHP. Don't do that — break out of PHP parsing mode. It's faster, neater, and easier.

I'm seeing a lot of things like:
<a href="javascript:showdiv('contentarea'); ajaxpage('home.html', 'contentarea'); changeZIndex(4);" title="Go to home page"...
