Split multi-contact .vcf address book into individual .vcf’s

Moving contacts from one phone to another is a tricky business. And when the manufacturers of the said two phones are different, this process quickly turns into a pain in the b**t.

It’s a known fact that Android (and, weirdly, older Sony-Ericsson) phones export their contacts as a single multi-contact vcf file. And it’s also a know (and hated) fact that Nokia’s (otherwise great) Suite program can only import single-contact vCards.

Migrating existing RAID1 volumes to bigger drives

Every once in a while hardware needs to be replaced. Sometimes boards, sometimes CPUs and sometimes drives. Drives are the ones most difficult to replace as they hold all that precious data one does not want to lose.

I personally hate reinstalling stuff; so I try as much as possible to “migrate” my data around. In this tutorial I’ll be replacing two drives under a RAID1 array with two newer bigger drives (and resize the array accordingly).

How to fix the Windows Updates available but list empty

Every once in a while Windows 7 manages to lose the list of available updates, and while it displays the correct number, the list for both important and optional updates are empty.

The only actual solution seemed to be a computer restart. However, there is an additional way to restore the updates list to proper functionality…

Handling processes / services on hibernation / wakeup in CentOS

Hibernation is a great feature on any computer. It allows for a temporary pause in execution in which the system in question can be unplugged, cleaned, modified, or moved.

But what happens when some services don’t play nice and fail to resume properly from sleep? Fortunately, Linux’s power management utilities provide the necessary functionality…

Maximizing Netgear WNDR4500v2 functionality with DD-WRT (USB, FTP, Samba, TFTP, Printer sharing)

The Negear WNDR4500v2 router is quite a beefy piece of hardware with advanced firmware, including plenty of features even for a maniac user like me.

I would most likely not have replaced it from day 1 however if it had one more feature that I absolutely needed: TFTP/PXE/BootP options for the DHCP server. There is where DD-WRT comes in…

Bluetooth peripheral device no driver installed/available

One may randomly encounter a Windows installation where some bluetooth devices don’t get their drivers installed despite having installed all of the manufacturer’s drivers.

In such cases, one may end up with one or several non-functioning “Bluetooth Peripheral Device”. To solve this, start by downloading and installing Windows Mobile Device Center 6.1…

Solving WordPress unable to upload media – another way

Working with Wordpress installations all the time, I get to encounter the weirdest issues. One of theme is the all-known “unable to upload media”, translated by Wordpress to a clear and yet useless message.

First step is, naturally, to check permissions. But what do you do when permissions are perfect, and yet Wordpress can’t upload?

KB2670838 and the font rendering issue in Firefox

Three months after installing KB2670838 and updating my graphics drivers from Catalyst Mobility 13.12 to 14.4 the font rendering issue popped up. Except I didn’t get issues with text rendered in pages, but in Firefox’s menu /tabs / titlebar itself.

Nobody would think an update installed that long ago could be the culprit. Everyone would think the newly installed driver is (and it definitely has something do to with the issue).
