Ever seen this screen in your Eclipse?
It was the most annoying until I turned on my brain cells to resolve it.
(when it really bored me to death)

Here is the screenshot:

Why this message appears?

There is a minor error in Flex plugin for eclipse/ Flash builder. It searches for the folder “plugins” inside the browser installation directory and if it doesn’t find flash plugin there, or directory “plugins”, it will open this dialog, even if you have plugin installed and working.
Pressing YES, will run as normal.

It normally occures in linux distributions which has only one place for browser plugins, like openSUSE. OpenSUSE has one directory for all plugins and it is located in:

/usr/bin/browser-plugins

How to fix?
Easy. just make symbolic link inside firefox directory to this one, naming it “plugins”. Here is the command:

worktux: cd /usr/lib/firefox
worktux:/usr/lib/firefox # ln -s /usr/lib/browser-plugins plugins

O virtuelnim mašinama je napisano mali milion opširnih članaka o svim mogućnostima i prednostima istih, međutim, malo ko razume sve što one mogu. Uključujući tu i mene. Sve je to previše “virtuelno” za jednog prosečnog korisnika, ali ipak, i previše korisno da bi se one zanemarile. Kako ja mnogo koristim virtuelne mašine (do duše, na najjednostavniji mogući način), mislim da vredi objasniti koliko su korisne.

Šta je u stvari virtuelna mašina? Virtuelna mašina, u daljem tekstu “VM”, je program koji radi unutar operativnog sistema, kao i svaki drugi program, ali za razliku, simulira drugi kompjuter. Drugim rečima, kompjuter unutar kompjutera. Kako je to program, omogućuje kreiranje bezbroj kompjutera unutar (fizički prisutnog) kompjutera na kome radite (mogući broj VM-a zavisi, zapravo, od mesta na disku).
Dobro, kompjuter unutar kompjutera, ali čemu to? Read more…

The problem: I need the easiest way possible to resize a bunch of images from a digital camera, or from one directory, and place them into another.

There are a lots of great tools for the job. As linux user, I had a choice of a variety of excellent applications to use, from large scale applications like GIMP or Krita, to small tools like BIRT. Lately, because I have KDE4, I used Gwenview because it supports batch resizing.

However, all of them ask you to select the files which you wish to resize. Well, I want all of them; I may have already prepared them in some directory by selecting them from various sources. So, file selection was just slowing me down.

Solution: Since I could not find a tool which would solve my problem, I made one.

Baires is an application that will resize all of your pictures that reside in a selected folder, and resize them to the same folder or another folder. Since it keeps ‘last used’ settings, next time resizing is just one click away.

Baires is an open source GUI application, made in Qt. It works on all platforms, but if you are not using openSUSE or Fedora linux, you’ll have to compile it from source. I have pre-compiled RPM packages for openSUSE 11.0 to 11.2, SLED/SLES 10 and 11, and Fedora 9-12, available for download.

You can download it from Baires download page

The first question you may ask is why to compile kernel in the first place? Well, since all companies/groups that makes Linux distributions wants their product to work on as many machines possible, kernel is compiled in the most generic way possible. That means that it is compiled for low-end processor and it includes all possible modules that kernel has to offer. It is obvious that it is made to work with everything and not to work fast. For example, you will see in many Linux packages, kernel included, filenames have some suffix like i386, i486, i586, i686… It means for which processor they are compiled. i386 and i486 will work on i386 and i486 old processors respectively, and higher, while i586 will work on Pentium 1, and i686 on Pentium pro. So, if you have, for example, Intel Core2, and you use i586 generic file, this means that all of the new and fast instructions that your processor have will be unused. So, if we compile kernel for our processor, it will run much faster.

U svom članku od 16-og marta Spajanje više video fajlova u jedan objasnio sam kako se jednom jednostavnom komandom mogu spojiti video fajlovi u jedan finalni. Kao komandu za to sam naveo

cat 1.mpg 2.mpg 3.mpg > final.mpg

Međutim, to baš i nije najsrećnije rešenje. Kada se video prebaci na Windows, Media player naročito, ne očitava dužinu trajanja fajla kako treba.
Bolje rešenje je sledeća komanda koja to radi baš kako treba:

Članak ispod uporedno prikazuje originalnu licencu, član po član i šta on znači na jednostavnom engleskom, koji svi mogu da razumeju. Obavezno procitajte. Članak je baziran na licenci “Windows XP Home”

>>>>> MS EULA in plain English <<<<<

Od svih katastrofalnih (po nas) članova licence, ovaj mi se najviše svideo:

Gmail is not allowing you to make nice HTML signature by default, ones like you can make in your Thunderbird, Outlook or any other mail application. However, every problem has it’s solution. One way or the other. Let me mention, this tutorial works only for Firefox or Firefox-based browsers, like Flock.

Dear AMD/ATI,

you said on your site that you needed to withdraw resources from development of older drivers. You said that it was necessary for you to focus all efforts on your new hardware. You said that it is for our own good, so we can have better experience.

Dear AMD/ATI, did you forget that video cards, that you called old, are 6 months old?
Did you forget that there are more than 10 million laptops in shops with yours, now unsupported hardware?
Do you know that all of that video cards does not work with Linux anymore?
Did you forget that number of Linux users is on the rise?

Dear AMD/ATI, why don’t you fully open your video drivers? There are people out there, who knows how to make it work. There are people who have time to make it work.

Dear AMD/ATI, I am very disappointed in your decision to forget me and the money I gave to have your product.

Dear AMD/ATI, I will never again buy laptop with your video card. NVidia didn’t open their driver either, but at least, their cards work and keeps working better with Linux.

Dear AMD/ATI, I am sorry, but you forced me to say ‘farewell’.

Once faithfully,
Emil Beli

I have seen that many of the junior Flex programmers have problems in understanding how events in Adobe Flex works and how should be used. So, I find a good thing to explain events a bit more. I have already wrote about custom events in this article. It’s time to go a bit deeper. Read more…

Few days ago, Mrs. Carla Schroder, managing editor of the Linux today magazine wrote a nice article on how software giants are considering users very stupid and turining its systems slowly into few button toys. She called it “Fisher-Price computer”, as Fisher-Price enterprise is the world’s biggest manufacturer of baby equipment and toys. And how, just maybe, Linux is for grown ups. You may read original article here.

I agree with her to a certain point, however, I will go deeper in why software giants considering users stupid. That’s because most of Read more…
