Some guy on Stack Overflow wanted to know how to highlight a piece of text in given page using jQuery. Finding proper solution for jQuery (client-side) took me around ten seconds as three most important search results were found on StackExchange and jQuery documentation itself. Anyway, here’s a copy of my answer.
Long long time ago in a galaxy far far away I wrote a very simple PHP script, that I usually put into index.php of a directory, which contents I’d like to print out to the browser. I’m using this solutions on all servers and hostings which has Apache-based directory listings disabled and thus are showing empty page or error screen, if folder does not contain index.php.
Here’s the code:
[code language=”php”]
$dir = getcwd();
if (is_dir($dir))
{
if ($dh = opendir($dir))
{
echo(‘Files in this folder:<ul>’);
while (($file = readdir($dh)) !== false)
{
if ($file != ‘.’ && $file != ‘..’ && $file != ‘index.php’)
{
echo(‘<li><a href="’.$file.’">’.$file.'</a></li>’);
}
}
closedir($dh);
echo(”);
}
}
[/code]
That’s pretty much everything, folks!
Ignoring folders using TortoiseSVN is a rather delicate thing. You must consider many factors, such as: whether file is or isn’t already versioned, whether file is needed for running application (i.e. file is junk or differs per computer and you don’t want to put it into repository, but must exist in local folder) etc.
I was once asked, if it would be possible to do step-by-step conversion of a large project written in pure PHP into Yii. In my opinion, it is possible, but absolutely not worth it.
Most professional frameworks are complete opposite to “pure PHP” code in actually all areas. Code is separated most times (i.e. into model, view and controller in MVC design pattern) and uses mostly framework classes or code. I would even say, that writing an application in some framework means using only 10-20% of pure PHP code and doing rest purely on framework classes, extensions, controllers etc.
In other words: porting a “pure PHP” application into framework code would mean writing that application from scratch. I’m not sure, if you would be able to reuse more than 5% of your original source code?
This article is based on information provided by QPKG package created for SVN by noski and on QNAP Wiki article about SVN and of course a piece of my experience. But since SVN is relatively easily to install by-hand (so you don’t actually need QPKG package) and since Wiki article about SVN is outdated / contains some garbage (directory /share does note belong to /dev/ram!), I decided to write my own guide.
The fastest way of generating passwords for htpasswd program is… to use PHP for this task:
[code language=”php”]
$clearTextPassword = ‘some password’;
$password = crypt($clearTextPassword, base64_encode($clearTextPassword));
echo $password;
[/code]
You may also (of course!) use htpasswd program or some 3rd party tools.
As for right know (when anything goes web and desktop applications are nearly dead) there aren’t many situations, when you would like to send an *.exe file as an attachment. But, suppose you want. Then you, the good question, is how to do this? Well… in general, you can’t do that. Gmail itself will block you from sending an EXE file directly or ZIP archive containing it. Saying that it did so, for the security reasons. And, even if you pass it over (see below), most mail servers will block you from delivering such contents to mailboxes operated on this or that server.

This article deals with installing Optware (IPKG) on QNAP TS-210 NAS machine. Optware is a must-have, if you want to do anything with your NAS that goes beyond using as simple network storage. I.e., if you want to access it via SSH and play a little around Linux on-board. In other words, in installs many core utils, that are simply gone from default distribution of Linux on-board QNAP.
I use my QNAP as backup stations and this for 99% of operations I mount its shares under my Windows. Once, for some non-typical backup operation, I had to do something exactly opposite — mount remote Windows share under QNAP. Since I’m quite Linux newbie, I had to wrote this down for future reference.
This is just a short notice, on how much data transfer and battery lose you should consider, when using Google Navigation.

Most QNAPs randomly mounts USB disk shares. I.e. you can have disk attached to left USB port as USBDisk1, second as USBDisk2 and after reset — changed together. This causes many problems, where being unable to write some script accessing particular disks could be named at first. There isn’t an easy way to work around it. The only solution I found out was to write an script that resides in flash memory (therefore is called upon each restart of QNAP) and that mounts disks under shares similar to their disk labels.
As a Windows-born user I was kind of surprised, that writing Linux version of autoexec.bat isn’t as easy task as it is under Windows (or formerly, under DOS, from which Windows has inherited this solution). Anyway, here is an example on how to execute bash script during every startup of QNAP machine.

You may try to use rm -rf [directory] to delete given directory along with all its content (including all subdirectiories and all files). Use this with caution, to not end up deleting all files on your root! :>
Note, that on QNAP (but not on regular Linux) you have to start your session as admin user, as you cannot use su command to become root. If you try this, you’ll end up with error su: user root does not exist.
The fastest way to get whole page or FTP directory contents is to use wget like this:
[code language=”shell”]
wget -r "ftp://dylon.co.cc/Shaun The Sheep (high res) – Series 1 and 2/"
[/code]
However, this may not work always, if destination is secured by password or requires login.
In this situation you may consider rsync…
Tables with multilevel lists inside are rather uncommon element of Microsoft Word documents, but sometimes this is the best solution, you can have. For example, when you need tree-like structure (multilevel list) on the left with additional columns to the right. But, in general, it is harder piece of cake to build and manage them.

If you simultaneously hold Power and Home at the same time, your Galaxy Tab will capture the screen for you. Images will be available right in gallery. Tip is comming from androidcommunity.com.
To go into the phone’s secret EngineerMenu type this combination: *#*#3646633#*#*.
This might be obvious for many, but since I found nothing doing quick Google, I wrote it down here for my future reference.
While playing with some extra features on my newly purchased QNAP TS-210 at some point I was forced to finally write some bash script to be able to control things, that are uncontrollable via administration panel. For this reason I had to learn myself at least basics of bash, that is installed on my QNAP. I used floppix page and linuxconfig.org Wiki as a base for my learning process (and source for this article), however I had to write down my own memo-list to be able to quickly find, what I’m looking for.
Let us understand it. Windows is stupid and idiotic system. Suppose, you store (remember) your NAS’s Samba username and password, so you don’t have to provide it, each time you access your local network share. If you thenchange your user password, Windows either won’t detect the fact that password has changed or, even if it detect it, it won’t show you login/password dialog box to provide new one. Instead, it continue to provide NAS with wrong (outdated) password.
After using QNAP’s web-panel to format external disk, it suddenly turned out that formatting to any partition type ends with extremely small free disk size. For example, completely empty (as should be after format) 1,5 TB disk, formatted to any Windows type (FAT32 / NTFS) has only 1,9 GB free space. Formatting it to any Linux type (Ext3, Ext4) ends with 1,84 GB free space and formatting to HPS+ with 1,89 GB. In all attempts disk has less then 0,2% free space right after format. Here is the solution, that I came up with after a lot of digging.

QNAP is built upon Debian, created and designed by a bunch of wise guys, constantly being improved and used around the world, sometimes in very important solutions. Thus, it is generally a safe and secured solution. On the other hand, there isn’t (there never was and there never will be) any thing, done by a human, that another human wouldn’t be able to breke, change, alter or destroy. So, there is always a good idea to improve security, whenever you’re possible to do so. This article discusses some smaller or bigger security holes in Samba on board QNAP with a possible solution or workaround.
Favicon (from “favorite icon“) is an icon displayed in certain places in web browser, when browsing any webpage supporting favicons. It can be displayed before address in URL bar, on browser tab, in favorites list, etc. This is mostly an icon (.ico file) in 16×16 or 32×32 dimensions.
The easiest way for your website to support it, is to put proper file in root folder of your domain or webpage, i.e. http://en.wikipedia.org/favicon.ico.
If you need more fine-grained control over this, then this article should help.

Some disks and partition management software (like Partition Commander and Partition Magic) are not prepared to work with disks (or partitions) format introduced in Windows Vista. And it will simply broken your disk, sometimes in the way, that even Windows Recovery Tool is unable to fix it. So, there is a good idea to find a good replacement.
