So, first thing I learned is to have the packages foremost and sleuthkit installed. Then I basically followed the steps laid out in the article Why Recovering a Deleted Ext3 File Is Difficult. It worked for me and only leaves me wondering why these steps couldn’t be automated a bit.

I followed the directions here:

These are the requirements for new system purchases. Well, the dual-core actually isn’t but all chips with virtualization extensions are dual core.
AMD Athlon 64 X2 3600+ Brisbane 1.9GHz Socket AM2 – OEM about $60
Intel Pentium D 930 Presler 3.0GHz LGA 775 – OEM about $90
Intel Core 2 Duo E6300 Conroe 1.86GHz LGA 775 – OEM [...]
I was working with the configuration tool puppet the other night and got this error message:
“err: State got corrupted”
Thankfully it wasn’t too big a deal, unlike in the wider world.
I managed to resolve a couple of issues with tuning the debian ip network stack today.
ip_conntrack_tcp_timeout_established – I have been setting this value to 86400 (1 day in seconds) instead of the default 432000 (5 days in seconds) via sysctl.conf. The problem is that debian loads the sysctl.conf values before the network is loaded [...]
I was helping a friend with recommendations for an LCD monitor to be used for a computer but also to phase out the television. I found the sweetspot to be the 22″ widescreen LCD for around $300.
Here are the 3 I proposed:
Acer AL2216WBD – @newegg, @anandtech
Acer AL2223WD – @newegg
BenQ FP222WH – @newegg

I think du may be the most intolerable command in linux. The info is sometimes so important but it can take hours to get. So in a search for something better I came across enh-du which does seem faster but not by enough.
Managed to catch the commit here. Looks good enough to try on a production system in the not too distant future.
So another day devoted to traffic shaping, particularly as it relates to voip. That means playing with traffic shaping rules, often with a distinct lack of documentation, and then testing to see if they make a difference. So today I learned about HFSC after reading a quote in a discussion about HTB CBQ [...]
I know ekiga is pretty well known but I was trying some different problems (after being frustrated with certain aspects of ekiga) and I stumbled on twinkle which I’m liking a lot better. Not only does it work better than ekiga and other free and open source softphones that I’ve tested, it also has security [...]
So it’s worth reading The performance test of 6 leading frameworks though I found it lacking. The methodology is so far removed from a real world scenario that it’s hard to be swayed by the numbers. The results were that Django comes out first in performance, followed by TurboGears and Ruby on Rails [...]
Well, it’s true, almost all web servers do not proxy efficiently to a cluster of mongrel servers as was detailed in “Yet another post on how to setup Ruby on Rails to deal with high traffic websites.” I tried, in order, apache 2.2, pound 2.0, nginx 0.4.13 which are the more popular web server [...]
Well, we’ve tried phpgroupware, vtiger, and request-tracker and we’re still looking for that solution that really benefits us as a small company trying to coordinate tasks, contacts. projects, and resources but is open source and freely available.
Not that I have a high traffic ruby on rails site yet but the time will come and I want to try and set it up well from the start. The main problem is that ruby on rails is not thread-safe so each request must be handled by a separate process. So generally [...]
I started playing with PowerDNS a couple of months back. It wasn’t trivial to install but it wasn’t difficult either. As I find myself needing to move forward on DNS I did some more reading and now I feel that PowerDNS is overkill and I’m leaning toward MaraDNS. MaraDNS seems to fit [...]
AnandTech has a great review of the state of video cards for the holiday season but what most interested me was his page on Ultra Budget GPUs. His conclusions were much the same as mine. At the cheapest end try to get a X1300 which should cost just over $50 [...]
So I upgraded a server to 2.6.18 as it had recently entered debian etch. There are some things I already like but one thing that I was hoping to gain, NCQ on the RAID-1 SATA drives, was not to be. Apparently this is because the sata_nv driver does not support NCQ nor is [...]
Postgresql 8.2 was released recently and a lot of people have been singing its praises for performance and robusteness. However the one thing that leaves me choosing mysql is the integrated replication. However I note that debian now has packages for slony and postgres 8.1 in etch (and perhaps 8.2 will make it in before [...]
On a whim I decided to see how much it would cost to get a dirt-cheap 64-bit system. I have a need for some web servers that do not need to be blazing fast and so will probably be made from parts purchased on ebay. But the temptation to have the cheapest, slowest [...]
Mostly my desktop upgrade from dapper to edgy went well, though there were a few hiccups along the way. The most serious problem was that neither silky nor gaim’s silc plugin were working after the upgrade. So I finally got an account on the ubuntu forums and wrote Silc support in Ubuntu: From [...]
