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.
I got a “DS1302 Serial Real Time Clock with Battery” very cheap off eBay (for under 2$) which I set up as a backup Real Time clock module on my Raspberry.
Hooking it up is pretty straightforward. The pinout and needed software are …
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).
There are times when devices fail, or lock up.
In some of those cases it could be a SATA hard disk locking up (perhaps it is developing bad blocks, perhaps it just had a power failure due to a bad connector and got left in an undefined state).
Thankfully, Linux offers vast control over the hardware…
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…
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…
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…
