Show / Restore missing Gimp 2.8 Toolbox Menu on Debian Wheezy 7.0 Linux

Tuesday, May 28th, 2013

After installing latest Debian Wheezy Linux on my Lenovo Thinkpad Notebook. One of first packages after very basic GNOME install was of course GIMP.

I edit images with GIMP mostly on daily basis, so life without GIMP is impossible…
Debian 7 comes with shiny new version of GIMP – GIMP 2.8. So far so good, but the problem is when started it for a first time, the default configuration is made in a way that it miss essential Gimp Panel Window (The Toolbox Window). Missing Brushes and selectors, move, scissors etc. is something really terrible.

My first guess was I can display it somehow from GIMP's View menu but after few minutes of try/errs I figured out this is not possible.

One menu I managed to displayed Toolbox in some mostly unusubale form, since they were not fitting well my 1024×768 resolution screen is via menus:

Windows -> Toolbox

Since this wasn't what I was looking for I spend some 10 minutes until I finally found "the fix". from menus:

Preferences -> Window Management -> Reset Saved Window Positions to Default Values

How to install Skype on Nokia n95 8G mobile phone

How to install skype on nokia n95 8G java client program

 I was asked if it is possible to install Skype on a Nokia Mobile N95 8G by a relative of a friend I remembered I've earlier installed and used Skype on my Nokia 9300i with some kind of Java Skype client, so I guessed installing Skype on Nokia N95 will be much easier and most likely supported by Skype.com's available mobile versions.

Further on, I tried downloading from Skype.com's client mobile download versions and after selecting the model of the Nokia N95 OS which is Symbia, was asked for a mobile number to which Skype will be send via SMS. I've typed in the Mobile number, hoping it will be the usual click on link and authorize Skype download and install on mobile, but instead Skype send me in SMS, just a link to Skype's Mobile download section  http://www.skype.com/m/ .

In other words, typing in the phone number and navigating through the URL from the mobile was completely useless. As I ended on the same place where I could manually browse using Nokia embedded Browser ….

Though I did my best to look through all the appearing links in N95's browser I was just redirected to either the same or similar page with  Skype Download button. After getting pissed off of looking and not finding any usable Symbian Skype app install binary (.SIS or SISX), I've decided to just look in Google. If some third party website is not storing  .SISX Skype bin for Nokia N95.  After few minutes of search I've found one offering an Archive with 3 versions of Skype. 2 of the .sisx files
, were versions of Skype which I've installed using Nokia Mobile Suite for Windows. Two of the .sisx files in archive Symbian Mobile Skype ver. 1.5 and Symbian Mobile Skype ver 5 did not work on N95. The binary that launched okay on the Mobile was Skype_S60_3_0_v_1_5_0_12.sisx. Though this binary launches the client and one can choose between the usual Sign In or Register new skype name buttons, it wasn't possible to login with the username and skype. After a bunch of prolonged waiting trying to Sign in the skype showed up again the Skype Login Name and Password prompts.

I spend some more time, trying to Install Fring – free mobile, chat, voice, video Skype substitute program, after reading on few Symbian Forums that fring is able to be used as a mobile substitute for Skype. Just a bit after installing it I've red on some forums some other posts from  2010, saying fring support for Skype is no longer available.  I tried also to login to Fring's client with Skype Login and Pass but login failed thus uninstalled Fring and continued researching online whether Skype can somehow be used on Nokia N95 mobile.

I've found a Skype Java (.JAR) same file version which I have also installed on my Nokia 9300i and downloaded and tried this one as well. Guess what it works 😉 It is not supporting Outgoing Skype users video clients, and it supports incoming Skype Video calls only with pre-purchased Skype call minutes, but Skype messaging works. I've made mirror of nokiaN95.jar Nokia N95 Java skype program here. I was lazy to research further if there is some other software or Skype.com symbian old version mirrored somewhere on the net working with the N95, but I guess it is possible. If someone reading this post knows a better Skype binary supporting Skype Video and Voice please drop a comment how ? Other way to use skype without loosing time to install Skype client is http://IMO.IM web Skype service

Fix Null error in WordPress comment reply with wordpress-threaded-comments plugin enabled

Friday, April 6th, 2012

I'm running WordPress for already 3 years or so now. Since some very long time. The first wordpress install, I can hardly remember but it something like wordpress 2.5 or wordpress 2.4

Since quite a long time my wordpress blog is powered by a number of plugins, which I regularly update, whenever new plugins pops up …
I haven't noticed most of the time problems during major WordPress platform updates or the update of the installed extensions. However, today while I tried to reply back to one of my blog comments, I've been shocked that, I couldn't.
Pointing at the the Comment Reply box and typing inside was impossible and a null message was stayed filled in the form:

To catch what was causing this weird misbehaving with the reply comments functionality, I grepped through my /var/www/blog/wp-content/plugins/* for the movecfm(null,0,1,null):

# cd /var/www/blog/wp-content/plugins
# grep -rli 'movecfm(null,0,1,null)' */*.php
wordpress-thread-comment/wp-thread-comment.php

I've taken the string movecfm(null,0,1,null) from the browser page source in in my Firefox by pressing – Ctrl+U).

Once I knew of the problem, I first tried commenting the occurances of the null fields in wp-thread-comment.php, but as there, were other troubles in commenting this and I was lazy to read the whole code, checked online if some other fellows experienced the same shitty null void javascript error and already someone pointed at a solution. In the few minutes search I was unable to find anyone who reported for this bug, but what I found is some user threads on wordpress.org mentioning since WordPress 2.7+ the wordpress-threaded-comments is obsolete and the functionality provided by the plugin is already provided by default in newer WPinstalls.

Hence in order to enable the threaded comments WordPress (embedded) reply functionality from within the wp-admin panel used:

Settings -> Discussions -> Enable Threaded (nested) comments (Tick)

Enable Nested Comments WordPress default wp comments enable reply functionality screenshot

You see there is also an option to define how many nested comments subcomments, can be placed per comment, the default was 5, but I thought 5 is a bit low so increased it to 10 comments reply possible per comment.

Finally, to prevent the default threaded comments to interfere with the WordPress Threaded Comments plugin, disabled the plugin through menus:

Plugins -> Active -> WordPress Thread Comments (Deactivate)

This solved the weird javascript null "bug" caused by wordpress-threaded-comments once and for all.
Hopefully onwards, my blog readers will not have issues with threaded Reply Comments.

How to convert AVI, MP4, FLV (flash video) and other non-free video encoded formats to Free Video format encoding OGV (Ogg Vorbis / Theora) on GNU / Linux and FreeBSD

Ogg Vorbis Free / Open Audio Video Format logo

I was looking for a way to convert some Video and Sound files, downloaded from Youtube (mostly things dedicated to free software) and as far as I looked online unfortunately these pieces of nice music and tutorials are not available for download anywhere else or at least not available for download in some of the Open / Free Format (OGG Vorbis or OGV (OGG / Theora Video).

When it comes to convertion between different formats, always the first things that I think of is ffmpeg or mencoder , however I was not sure if some of this tools are doing the trick so I did a quick research online if there is some specialised console or GUI program that can do the convertions between MP4, FLV etc. to OGV.

In less than 10 minutes I found a threat mentioning about ffmpeg2theoraA Simple Convertor to create Ogg Theora files

As I’m running Debian GNU / Linux, I installed ffmpeg2theora straight via apt, according to some reports online ffmpeg2theora cmd convertion tool is also available straight from repositories on Ubuntu as well.
On FreeBSD there is a port /usr/ports/multimedia/ffmpeg2theora available for install. Of course FFmpeg2Theora can be installed from source on other Linux distributions that might be missing a pre-built binary.

Using ffmpeg2theora to convert some kind of non-free video format is very simple, though the tool provides quite a numerous options for all those who want to have some customization for the video to be converted.
To convert the flash file “The Gnu Song.flv” for example to The Gnu Song.flv , I invoked ffmpeg2theora like this:

debian:~# ffmpeg2theora "The Gnu Song.flv"
...

The conversion took few minutes of time, as my machine is not ultra powerful and apparently the conversion to OGV format is not too quick but the good news is it works.
After the conversion was completed I used ogginfo to check the information about the recent converted file The Gnu Song.flv , below you see the file info ogginfo returns

debian:~# ogginfo The Gnu Song.ogv
Processing file "The Gnu Song.ogv"...

ogginfo is a part of a package installed under the name vorbis-tools, vorbis tools also contains a few other helpful tools, whether operations with OGV or OGG file formats are at hand, the complete binaries vorbis-tools contains on Debian as of time of writting this post is:

/usr/bin/ogg123
/usr/bin/oggenc
/usr/bin/oggdec
/usr/bin/ogginfo
/usr/bin/vcut
/usr/bin/vorbiscomment
/usr/bin/vorbistagedit

ogg123 is a player for ogg files, however as far as I’ve tested it it doesn’t work too well. And just to compare ogg audio files were played just nice using the play command.
oggenc is used to encode ogg audio file, based on a stream haneded to it from other audio encoded stream (let’s say mp3). Hence oggenc can be used to convert mp3 files to ogg audio files , like so:

debian:~# mpg321 input.mp3 -w - | oggenc -o output.ogg -

oggdec is used to convert to wav files or raw PCM audio, whether;
vcut is used to cut ogg video file on parts.
vorbiscomment and vorbistagedit is used to edit information on already existing ogg audio files

There is also a GUI programmer for people who doesn’t want to bother with writting on the command line called oggconvert . OggConvert is written for GNOME and uses GTK gnome library, here is how the program looks like:

How to suspend Cpanel user through ssh / Cpanel shell command to suspend users

Friday, August 5th, 2011

One of the servers running Cpanel has been suspended today and the Data Center decided to completely bring down our server and gave us access to it only through rescue mode running linux livecd.

Thus I had no way to access the Cpanel web interface to suspend the “hacker” who by the way was running a number of instances of this old Romanian script kiddies brute force ssh scanner called sshscan .

Thanksfully Cpanel is equipped with a number of handy scripts for emergency situations in /scripts directory. These shell management scripts are awesome for situations like this one, where no web access is not avaiable.

To suspend the abuser / (abusive user ) I had to issue the command:

root@rescue [/]# /scripts/suspendacct abuse_user
Changing Shell to /bin/false...chsh: Unknown user context is not authorized to change the shell of abuse_user
Done
Locking Password...Locking password for user abuse_user.
passwd: Success
Done
Suspending mysql users
warn [suspendmysqlusers] abuse_user has no databases.
Notification => reports@santrex.net via EMAIL [level => 3]
Account previously suspended (password was locked).
/bin/df: `/proc/sys/fs/binfmt_misc': No such file or directory
Using Universal Quota Support (quota=0)
Suspended document root /home/abuse_user/public_html
Suspended document root /home/abuse_user/public_html/updateverificationonline.com
Using Universal Quota Support (quota=0)
Updating ftp passwords for abuse_user
Ftp password files updated.
Ftp vhost passwords synced
abuse_user's account has been suspended

That’s all now the user is suspended, so hopefully the DC will bring the server online in few minutes.

How to fix transmission unable to download and connect to torrent tracker on Ubuntu Maverick 10.10

Wednesday, April 27th, 2011

As you can read in my few previous posts I have just installed a new Ubuntu 10.10 on a Toshiba Satellite L40 notebook.

Most of the things which are necessery for a fully working Linux desktop are already installed and the machine works fine, however I just noticed there is an issue with the default torrent gnome client and transmission unable to download files from torrent trackers.

Few minutes of playing with the transmission’s settings has revealed what was causing my torrent download problems.

It seems on Ubuntu 10.10 (probably on other Ubuntus and Debians) by default the transmission bittorrent client is trying to use for torrent download connections an incoming port 53636 number.

As the computer is behind a firewall and does not have a real IP address seeders cannot properly connect to the notebook port 53636 and hence the transmission bittorrent client could not initialize any torrent downloads.

Fixing up the issue is rather easy to fix it I had to change the settings in transmission from the menus:

Edit -> Settings -> Network

You need to select the options:
 

  • Pick a random port on startup
  • Use UPnP or NAT-PMP to redirect connections

Next I had to restart transmission and my torrent downloads started 😉
