Simple script for showing contents of a folder

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>’);


That’s pretty much everything, folks!

Is it possible to convert working pure PHP appication to Yii

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?

Installing SVN on QNAP using IPKG (Optware)

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is relatively easily to install by-hand (so you don’t actually need QPKG package) and since Wiki article about SVN is outdated / contains some garbage (directory /share does note belong to /dev/ram!), I decided to write my own guide.

Sending *.exe files through GMail and other mail servers

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.

Installing Optware (IPKG) on QNAP TS-210

Outdated article! Read the updated version instead.

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.

Fix for problem with mixing USB shares on QNAP

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.

Remove non-empty directory on QNAP or Linux

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.

Tables with multilevel lists inside in Microsoft Word

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.

Introduction to bash scripts

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 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.

No Samba access after password change

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.

Incorrectly formatted external disk on QNAP TS-210

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.

Patching some security problems in Samba

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.

If you need more fine-grained control over this, then this article should help.

Handling Apple’s .dmg files in Windows

If you just want to look into (or extract) contents of .dmg file, a good, old and free 7-Zip will take care of this. This should also work for Apple .sparseimage files. But, beware that (just like in case of .iso files for Windows) these formats can contain bootable information and or whole disk images (Apple .hps files), rather useless under Windows. So, for example, if someone tell you that he has Windows XP image ready to be used in VirtualPC for Macintosh, keep in mind that you rather won’t be able to use in in Windows version of VirtualPC. Or you’ll have a lot, lot of work with extraction, conversion, tune-up etc.
