PHP mb_ucfirst Make a String’s First Character Uppercase-Multibyte (UTF-8) Function
PHP’s ucfirst function is very usefull when you want to change words first letters to uppercase and other letters to lowercase. Currently on PHP does not have a multibyte (UTF-8) version of ucfirst function. So I decided write my own multibyte mb_ucfirst function.
Perhaps the multibyte version of ucfirst function is added later on PHP, so that’s why is better add this function only if it does not already exist.
PostgreSQL Sleep Function pg_sleep – Postgres Delay Execution
One day, I was looking for PostgreSQL database function, which could delay the execution of queries. At first I thought that I will do one myself, because I do not remember ever seen this kind function. But then I found pg_sleep Postgres function which directly delay execution of the server process.
pg_sleep makes the current session’s process sleep until seconds seconds have elapsed. Seconds is a value of type double precision, so fractional-second delays can be specified.
PostgreSQL: Select a Random Number in a Range (Between Two Numbers)

SELECT random() FROM generate_series(1,5); random ------------------- 0.595817462075502 0.350072300527245 0.989073566626757 0.700899163261056 0.940509075298905 (5 rows) Next thing to todo is convert random function values to real float values in a range 1-100:
SELECT random() * 99 + 1 FROM generate_series(1,5); ?column? ------------------ 45.0829070857726 96.3123500789516 30.1867960244417 63.0484761050902 44.2645903658122 (5 rows) And finally truncate floats to integers with trunc function:

Upgrade to Fedora 13 from Fedora 12 with Preupgrade

This guide I use preupgrade-cli version, which works from command line. If you want use Preupgrade Graphical version then you can check this Howto upgrade Fedora 11 to Fedora 12 with Preupgrade guide, which works same way with Fedora 13 (Goddard).

Fedora NetInstall (Net Install) with gPXE and BFO (boot.fedoraproject.org)
This is guide with screenshots, howto install Fedora (currently Fedora 13) with gPXE and BFO (boot.fedoraproject.org). BFO combines a series of recent technologies to produce a new boot stack. The glue that holds everything together is gPXE. Boot method is similar to PXE Boot. It uses very small images (iso, floppy, disk) to bootstrap a machine that then contacts a remote server for boot information.
Why Should Use BFO Instaed of Normal Installer Image? The BFO downloads are very small and once you have them, you’ll rarely have to download more. Even as more versions of Fedora come out, you just boot from your iso and they will appear. Users with fast internet connections will have the best experience with BFO. They basically replace having to regularly download large CD/DVD ISO images and burn them to disk. gPXE supports following techniques HTTP, DNS, TFTP, AoE, iSCSI, bzImage, COMBOOT, ELF, Multiboot, PXE, PXEXT.
YUM/DNF Remove Repo – YUM/DNF Disable Repository
Quick guide, howto remove and disable YUM/DNF repo (repository). Yum/DNF command itself does not contain any way to remove the repository. YUM and DNF repo files are located in /etc/yum.repos.d/ directory.
I use skype-stable.repo file with following content as example on this guide:
[skype-stable] name=skype (stable) baseurl=https://repo.skype.com/rpm/stable/ enabled=1 gpgcheck=1 gpgkey=https://repo.skype.com/data/SKYPE-GPG-KEY Remove YUM/DNF Repo (Repository) Permanently Before deleting repository permanently is a good idea to check that is the repository installed using rpm package. As many repos usually are, like RPM-Fusion, Epel, etc.
