Apple – Extending an wireless network

casper — Sat, 17 Dec 2011 22:52:04 +0000

One of the thing when one buy a wireless only computer like an Apple MacBook Air (USB 100mb/s sucks), is that the next thing one start looking at is to get 802.11n, which currently is the fastest option for wireless. There are many options out there, some of them good, some less. I decided to [...]

WMware ESXI – suspend all guests

casper — Sun, 04 Dec 2011 18:03:14 +0000

I have an VMware ESXI 5 which I used for testing things, but I don’t want it to run all the time, and using the vSphere Client to stop all the VM’s and then stop the ESXI server is a bit too much effort.

So I figured out how to do it from the [...]

RHEL6 – disable IPv6 on an interface

casper — Tue, 22 Nov 2011 20:57:26 +0000

I’ve been having fun upgrading, or should one say migrating to RHEL6 (Scientific Linux 6.1). As run KVM (Virtualization) I have a bridge running for my VM to connect to the network.

Now I suddenly noticed that IPv6 was enable on my ‘eth0′ which is part of the bridge, this should not happen as [...]

OSX Lion Preview slow to start

casper — Thu, 15 Sep 2011 06:10:22 +0000

If you as me is running OSX Lion, and find that Preview is incredible slow to start, and for some reason it also load all the previous seen files, well then welcome to the new “Resume” feature which Apple have introduced.

I like it for some programs, but with Preview it slowed it down so [...]

As some might have noticed, I have a “Recent Books” in my sidebar, and some might have wonders how it got there, well some time ago I decided to get a bit more handle on my books, as I started buying duplicates. Due to getting a license to DeliciousLibrary fairly cheap via

Linux – CentOS5 and software raids…..

casper — Sat, 28 May 2011 21:10:26 +0000

We all like RAID, and with Linux it’s a pretty cheap way to get enough space to store ones DVD/Music collection, I run a fairly large RAID5 which is working without a hiccup, but much to my surprise I was checking my /proc/mdstat and saw:

md5 : active raid5 sdh1[4] sdg1[3] sdf1[2] sde1[1] sdd1[0]

AirTunes – forked-daapd and Airport Express

casper — Thu, 14 Apr 2011 10:45:26 +0000

One small issue one can run into after installing forked-daapd is that using the iPhone/iPad remote one cannot play any songs.

Looking in /var/opt/forked-daapd.log one will see something:

[2011-04-14 11:24:59] laudio: Could not open playback device: No such file or directory

Linux – Software RAID speed

casper — Sat, 02 Apr 2011 11:54:23 +0000

Having reshaped a RAID5 twice of as many weeks, I’ve found that adding a 2TB drive takes a good 36 hours, which is kind of frustrating.

After a bit of searching, I discovered that there is a setting in /sys/block/md*/md/stripe_cache_size which by default is set to 256. This is enough for normal day operations, but [...]

Apple AppStore & iTunes Ping

casper — Fri, 07 Jan 2011 15:57:04 +0000

I really think it’s great that Apple develop all these cool things to make the experience of using their software an really nice and relaxed experience.

But, as there is always a but in there, they absolutely silly and annoying way they chose which language one can use would be something someone should be @$!@#$!@$%@#$% [...]

Missing your Facebook contacts in Adium?

casper — Fri, 26 Nov 2010 23:19:03 +0000

There is a problem with the protocol Adium used to implement the Facebook Chat, which means that some people have problems seeing their contact (they are not there…).

As of Adium 1.4.2 this will be fixed as Adium is moving to the new protocol – or they say they are.

As per this
