A quick tip for command line users: if you want to convert .png files to .pdf:
Simple! If you want to keep control of page sequence or specific files to convert:
Needless to say, but I’ll say it anyways, the .pdf won’t be in vector graphics, so not scalable but that is because .png is not a vector graphics format.
For those who are vim fans, a quick tip on how to run a diff/merge task:
Open the files with:
To jump between files:
To jump places where differences are found:
These are just the quick basics, there are a ton of other commands listed on Vim’s documentation page.
Here is a simple and quick way for you to encrypt files in Linux:
gpg –output doc.gpg –encrypt –recipient [email protected] original_file.doc
Further explained:
–output (or -o) is the name of the encrypted file –recipient (or -r) is the person who will be decrypting the file. If the file is for yourself only, use the email address of your GPG key. To decrypt:

Which means:
it is now easier to jump between different accounts (Gwibber supports Identi.ca, Twitter, Facebook, Digg, StatusNet, Flickr and more). You can easily post to only one account. Easy “re-dent” / “re-tweet”. I’m sure there are more behind the scenes improvements but so far I haven’t seen any list. For now, the upgrade was worthwhile.
If you’re trying to recover deleted files or files in a corrupted partition, you might want to give Magic Rescue a try. With this command-line tool you will basically be looking for specific file types (searching by their extension). So, for a massive file recovery task, it will not be a good approach.
The program uses what it calls “recipes” as the instruction of which files to look for and how to do so.

If you want to run a WebKit web browser with no strings attached (unlike Safari and Google Chrome), Arora is surely worth a try.
First plus is that it runs on Linux, Windows and MacOS X. It is fast, has private browsing and looks like it has some plug-in support. Another good news is the announcement Kubuntu will carry Arora as its default browser in the 9.10 release.
Not long ago I was working with some .po files and needed a nice and simple diff program to merge 2 files. First I tried the multi-purposed text editor vim.
Using vim as a diff and merge tool:with Andrej’s articleI found some nice tips & tricks and the Vim manual for difftasks. Some useful commands,
“vim -o one.txt two.txt three.txt” (for horizontal split), “vim -O one.txt two.txt three.txt ” (for vertical split) go to the next diff point ” ]c “; go to previous diff point “ [c “ merge to original “do“, merge from original “dp“.

Gnash, the freedom alternative to Adobe Flash Player now supports displaying YouTube movies!
The to-do listfor Gnash is still pretty large until we’re all freely able to browse the web without the Adobe plug-in. But, at least this is some major good news I found out today.
Now let’s hope html5gives us more goodies and web developer adopters to make Adboe Flash Player even less needed.
Update: I was hoping I could use Gnash completely now but unfortunately a lot of websites are still not functioning well with it (such as Google Analytics) so I had to remove it.

Although it has been a round for quite some time, I’m not a coder so my experience with text editors and IDEs is very limited. To give you an example, I’ve been using on the command line the good-ol’ simple nano. But, since I’m starting to need a bit more powerful features, my search began for a more powerful program.
Emacs was my first try since it has been highly rated and praised.
