Adventures in entropy, part 2

Monday, June 7th, 2010

Recap
Back in part 1 I discussed what entropy is as far as Linux is concerned, why I’ve started to look in to entropy as it relates to a Linux/Xen-based virtual hosting platform, how much entropy I have available, and how this might be improved.
If you didn’t read that part yet then you might want to [...]

Adventures in entropy, part 1

Sunday, June 6th, 2010

A while back, a couple of BitFolk customers mentioned to me that they were having problems running out of entropy.
A brief explanation of entropy as it relates to computing
Where we say entropy, we could in layman’s terms say “randomness”. Computers need entropy for a lot of things, particularly cryptographic operations. You may not think that [...]

DNS serial Nagios plugin lazyweb request

Thursday, March 18th, 2010

Dear Lazyweb,
Anyone got a Nagios plugin that will take a domain as argument, work out its list of nameservers and alert if the zone serial is different on any of them versus the serial on the host that the check is running against?

Linux software RAID hot swap disk replacement

Sunday, January 17th, 2010

One of BitFolk’s servers in the US has had first one and then two dead disks for quite some time. It has a 4 disk software RAID-10, so by pure luck it was still running. Obviously as soon as a disk breaks you really should replace it, preferably with a hot spare. [...]

My root file system doesn’t show up in “df” anymore!

Thursday, November 26th, 2009

Earlier tonight I had a strange bug report from a customer. Ever since I’d moved his VPS from one host to another, he’d stopped being able to see how much disk space he had free.
At first I thought it was simply because when I had moved his VPS I had taken the opportunity to [...]

More abject Abbey failure

Monday, October 26th, 2009

Last year Abbey screwed up and caused me significant problems in my day to day BitFolk business. They were unable to convince me that they would improve in future, so I voted with my wallet and BitFolk sought another bank for business purposes. I had to keep the abbey accounts open though because [...]

Some harsh realities

Sunday, June 21st, 2009

Recently BitFolk has been accused of overcharging for disk space.
In general I don’t try to defend BitFolk’s price-point – the unmanaged VPS hosting market is flooded and it is very easy to find stuff hosted out of the US or continental Europe for just a couple of pounds per month. Clearly I am not [...]

UKNOF 13

Thursday, May 28th, 2009

Today I made my way up to Sheffield to attend the UK Network Operators’ Forum’s 13th meeting. UKNOF is something I’ve wanted to attend many times in the past as there has always seemed to be a very interesting set of presentations, but I could never convince my employer to let me do so [...]

Do No Evil

Wednesday, March 11th, 2009

Google Checkout just announced that they’re going to put their transaction processing fees up to 3.4% + £0.20, from 1.5% + £0.15. This brings them to exactly the same price point as Paypal, and represents around a 250% increase in the cost of processing a transaction.
I don’t really see what the point is in [...]

Abbey Anger

Tuesday, December 9th, 2008

This is a really long rant about Abbey business banking. If you have no interest in such a thing or are already convinced of the incompetence of Abbey / Santander Group then there is probably no point in reading further.
Bitfolk’s business account is and has always been with Abbey business banking. The initial [...]
