There is a keyboard shortcut that simplifies this procedure. If you need to open search results in a new page, you have to select the text you like to search for, then Hold Ctrl+Shift, then Right click your mouse and select “Search“. It’s very strange that I cannot do this without pressing two additional buttons on the keyboard, anyway, this is simpler than to copy and paste the text you look for. Hope this saves you some time.

The solution is very simple. The only restriction is that you should have rights to use exec() or system(). Though, I don’t think there is any reason to deal with the paths if you are not allowed to run system applications. Here is the code:


$var=exec ("which unzip");
echo $var;


What does this code do? It catches the output of system which command to a variable. Then you can use this variable for your purposes. Of course, you should verify the value of the variable before using it. You may also need to echo something, if unzip is not installed.

This technology can be applied to any other system binary you need to know the path of. $var=exec (“which sh”); will tell you the location of sh, if you need to run any shell scripts with your PHP script, and so on.

Several years ago a famous Russian payment system named Fethard has faced problems just like these. Funds were frozen for an undefined period of time. I haven’t seen any changes during last years, and I was happy I had no money there. But most people that had funds there have not received them yet. Since I have been living online for last 7 years, I think I can give some advices to newcomers.

1. Do not store big amount of funds on Online Payment Processor accounts. These systems are not as trusty as bank accounts and bank issued credit cards. If your account is blocked, you’ll have to wait until the situation is resolved.

2. Do log in to your online accounts frequently. I have an issue with Moneybookers, that’s why I already know that it is important. You should log in at least once a week to ensure that there are no problems.

3. Ensure that all the necessary verification steps are done. Most online payment systems require to upload documents, recent utility bills, etc. It is a good practice to contact them to find out whether you can do anything to verify your account. If something goes wrong, it is important to have a verified account.

4. Write down all the contact details for these payment systems. If their site goes down, you can get in touch with them using these numbers. Some payment providers have even ICQ support (Like Epassporte’s Michael).

5. Do not send money to unauthorized and potentially fraudulent accounts. Even if you’re planning to deal with some stuff like that, create a separate account and don’t touch your official one

6. Do not leave payment memos blank. If you perform any transfers using your online accounts, make sure that your payments have “human readable” destinations.

7. Withdraw your funds frequently. This seems to be easy enough, the only thing is you need to have funds to withdraw. This means: receive as many funds as possible

Hope this information saves you from potential financial losses.

You can get this error on software update. For example, when trying to update ImageMagick:

-bash-3.1# yum update ImageMagick
Loading “installonlyn” plugin
error: no dbpath has been set
error: cannot open Packages database in /%{_dbpath}
Traceback (most recent call last):
File “/usr/bin/yum”, line 29, in ?

File “/usr/share/yum-cli/yummain.py”, line 82, in main
base.getOptionsConfig(args)
File “/usr/share/yum-cli/cli.py”, line 206, in getOptionsConfig
errorlevel=opts.errorlevel)
File “/usr/lib/python2.4/site-packages/yum/__init__.py”, line 132, in
doConfigSetup
self.conf = config.readMainConfig(startupconf)
File “/usr/lib/python2.4/site-packages/yum/config.py”, line 598, in
readMainConfig
yumvars['releasever'] = _getsysver(startupconf.installroot,
startupconf.distroverpkg)
File “/usr/lib/python2.4/site-packages/yum/config.py”, line 661, in
_getsysver
idx = ts.dbMatch(‘provides’, distroverpkg)
TypeError: rpmdb open failed

Let’s see the error message. It tells us: error: no dbpath has been set. How should we proceed?

First of all, you need to try to clear the database. Here is the set of commands that should help you to do this:

#yum clean all
#rm -f /var/lib/rpm/__db*
#rpm –rebuilddb
#yum update

If this doesn’t help, here is another set:

#rm /dev/urandom
#mknod -m 644 /dev/urandom c 1 9

After that, run

#yum clean all

This should do the trick.

In order to setup automatic start, we will have to deal with /etc/init.d/rc.local . This is the file, that is processed on system startup and it will allow you to run anything you like. We need to start Apache using /usr/local/apache2/bin/apachectl start. Let’s add this string to the end of your /etc/init.d/rc.local

#!/bin/sh
#
# This script will be executed *after* all the other init scripts.
# You can put your own initialization stuff in here if you don’t
# want to do the full Sys V style init stuff.

touch /var/lock/subsys/local
/usr/local/apache2/bin/apachectl start

That’s all! Now your httpd daemon will be automatically started at boot. You can start any daemon this way. If you know any more methods to start daemons, please, add them in comments.

Windows mobile devices are used to connect to the Internet when necessary. Especially, if you are using any custom ROMs, there are lots of software that require Internet connection. For example, Weather forecast plugins and time synchronization software, automatic E-mail check and so on. Every time the connection is established, it requires your phone to use a higher frequency (GRPS or 3G connectivity, that depends on your carrier). After your software has performed data exchange, the connection remains unterminated. This means it starts draining your battery and you have to charge it again and again.

The solution is to enable automatic disconnection for all GPRS connections. It won’t affect your working software, as even ICQ keeps sending pings to the server, or some dummy packets to keep connection alive. There is a registry tweak, and let me show you where it is.

I am using Total Commander for Pocket PC to edit my device’s registry. It’s free, but you’re welcome to use any shareware solutions. Open your favorite registry editor and navigate to the following keys:

HKEY_LOCAL_MACHINE\Comm\ConnMgr\Planner\Settings\
SuspendResume = GPRS_bye_if_device_off
CacheTime = xxx (where xxx are seconds before auto disconnect)

The first value isn’t so easy to change with Total Commander, that’s why I would suggest you to install a CAB file that will do this for you. Here is the cab that will enable GPRS auto disconnect after 60 seconds of inactivity. Of course, you can change CacheTime parameter to any value you like. I have left it at 300 seconds.

This works perfectly on my Acer S200 and it should save battery of any WM device.

find /path/to/folder/* -mtime +7 -exec rm {} \;

Please, note, that you need to keep spaces between command arguments.

This command is suitable for folders that contain a large number of files. In order to force file deletion you need to add -f key.

find /path/to/folder/* -mtime +7 -exec rm {} \;

If you need to move these files instead of deletion, here is the solution:

find /path/to/folder/* -mtime +7 -exec mv {} /path/test-mv-to/ \;

Hope this helps you to deal with archive files and big folders.

Let me mention that I don’t have a USB DVD-ROM drive, that’s why I had to deal with flash disks. I have tried to create some bootable flash drives, and let me share the software that has a simple and user-friendly interface, and, of course, it’s free. It is called WinSetupFromUSB and you can download it using the link above. It allows you to create a bootable installation flash drive to install almost any version of Windows you like.

I have tries some flash drives, but none of them allowed me to boot. I have tried all possible BIOS settings, but result was the same each time: error message telling me “Reboot and select proper boot device”.

The solution was very simple, yet not documented. If you need to boot your EEE 901 netbook from a flash drive, you have to try hitting and holding-down the [Esc] key when the ASUS splash screen appears during the boot-up process. It will then show you the boot menu. I can’t understand the reason, and there are no official docs from ASUS (I haven’t found any of them).

I would like to say a special thank you to guy from Eeeuser forum, their solution really helped me to find out the simplest way to boot from my flash drive.
