Attack by ZmEu

Who is ZmEu?

An image showing ZmeuThe name Zmeu (no capital E) is the name of a fantastic creature of Romania. There are so many stories that there isn't a clear understanding of what it is... but it is human like, can spit fire and wants to marry young women.

If you're wondering, it is generally a bad guy.

ZmEu Attack

Today, I noticed a lot of traffic on one of my servers. Looking into what was happening, I immediately found out that an attacker was looking for a loophole in that system. That attack was being performed from China.

QEMU tricks and reference

Today I tried to run WinXP on my newly upgraded Linux Ubuntu 12.04. It did not work... that's because the aqemu graphical interface tries to run qemu which was replaced with specially named emulators: qemu-i386, qemu-system-x86_64, etc. (try ls /usr/bin/qemu* to see a complete list on your system.)

So... I got the command line from the aqemu graphical interface, did a copy / paste and replaced the name with qemu-system-i386 and got the emulator started as expected. That worked fine, but then the window remained small (640x480) which I wouldn't care much if I weren't really using ...

Setting up an array of JavaScript functions in jQuery

Today I worked a bit with jQuery to create an advanced form. Advanced just because it is tabbed and appears in a pop-up, nothing too major really. Maybe later I'll add some tests to validate the data being entered before someone can submit the form...

In any event, I ran in a problem which was to create a set of click callback functions (event handlers) and each of which should make use of a different index. So... I have 4 tabs and each one has a number: 1, 2, 3, and 4.

Say I call each one of these numbers #tab1, #tab2, #tab3, and #tab4. Now I want to create a click function on each one ...

Drupal paths that won't work!

As I created a new site to list all of my accounts on the Internet, I thought the folder where those accounts appear should be called profiles. But somehow autopath did not generate the URL Alias as expected.

http://www.alexiswilke.me/profiles/

I tried several times and each time it returned an empty alias. Then I tried adding the alias by hand and that was accepted by Drupal, but when I then tried to go to that page it failed with an Apache error which at first I found odd. Then I recalled that there was a folder named profiles in the top directory of Drupal. The Drupal code (from the

Taxonomy error generated from invalid nodes

Today I ran in an error that looked like this:

Invalid argument supplied for foreach() in <path>/modules/taxonomy/taxonomy.module on line 1214.

The line number may vary depending on the version you are using. At the time, I had Drupal 6.14 and the line number was 1214.

The problem is with a node that has an invalid definition of its taxonomy field. In other words, the $node->taxonomy is not defined. If it were an empty array, the function would not fail.

Failing INSERT INTO without errors

Story

Inserting a row ina database is done with the INSERT INTO command line. This is quite standard SQL.

MS-Access supports the INSERT INTO instruction too. You can write macros that make use of it.

I have used it for a while and had not problems. But yesterday I discovered that there was a case when it simply wouldn't work at all. The strangest thing was that it did not work with an MS-Access database without any one error. No error at all.

IrfanView

I created this page to have a place to save my copy of IrfanView.

I have to say that the author has made his download so complicated (at least last time I tried it was deadly complex!) that I have to just keep my own copy somewhere. Maybe it's illegal, but the software is freeware anyway.

You can find the original (and most certainly more advanced version) on his website: http://www.irfanview.com

There other tools one can use to work on images as follow:
