krane.io – multi-cloud Docker
I don’t normally blog about Flexiant related stuff here, but this is a fun open-source skunkworks project, so I’m making an exception. We’ve released krane.io, an apache licensed tool that allows you to use the Docker command line you are familiar with across multiple clouds. The announcement is below, but you’ll get a better idea… — read more

How to use your BeThere Bebox with Sky in bridged mode and a Mikrotik router
I had a connection with BeThere with my BeBox in bridged mode, with a Mikrotik router behind it. My connection got migrated to Sky when Sky bought the Be business. I lost all but one of my static IPs, but more importantly, bridged mode stopped working. I rung Sky and their helpful advice was that… — read more

Nominet Registrar Agreement Consultation
Nominet has a consultation out on changes to its registrar agreement. In short, this one isn’t too bad. The big news is it proposes splitting registrars into three tiers: self-managed, channel partner, and accredited channel partner. I think the first category is too restrictive and would actually save Nominet a lot of bother if it… — read more

Net Into Dire Muck (an anagram of Nominet Direct UK)
I’ve written before (here, here and here) on Nominet’s proposals for registrations in the second level domain. That means you can register example.uk rather than example.co.uk. Superficially that sounds a great idea, until you realise that if you have already registered example.co.uk you’ll either have to register example.uk (if you even get the chance) and pay Nominet and… — read more

Changes to QEMU’s timer system
This article explains a little about how the timer system works in QEMU, and in particular the changes associated with the new timer system I’ve contributed to QEMU. What to timers do? Timers (more precisely QEMUTimers) provide a means of calling a giving routine (a callback) after a time interval has elapsed, passing an opaque… — read more

Four fours
Over the weekend I wrote a little ugly perl in order to solve the ‘four fours‘ problem. Essentially the problem is to make as many positive integers as you can, using only four occurrences of the digit ‘4’, and some mathematical symbols. For instance: 17 = ( 4 * 4 ) + ( 4 / 4… — read more

Changes at Nominet that I support
I suppose I have been quite critical of Nominet recently (here, here, here, here, here, here, here, and here, for instance). So I am pleased to say they’re suggesting something today with which I agree. Today Nominet announced a ‘program for evolving the .uk namespace‘. Much of the release is to do with a new consultation… — read more

Algorithm puzzle: Elves, Cakes and Gremlins – my solution #2
This post is the continuation of my answer to the elves, cakes and gremlins puzzle. One remaining question is the validity of the assumption that its quick and easy to find a value of S that is coprime to the value of L. I blithely asserted this easy, as the probability that two numbers are… — read more

Algorithm puzzle: Elves, Cakes and Gremlins – my solution #1
Here’s my answer to the elves, cakes and gremlins puzzle. I’m quite sure this is not the only solution, and it may well not be the best solution, but I believe it works. I think the key to this puzzle is criterion 3: “Assuming there is at least one locker that remains empty throughout an… — read more

Algorithm puzzle: Elves, Cakes and Gremlins
A locker room contains a number of lockers (L), and a number of elves (E). The elves are attempting to put cakes in the lockers, cake by cake, to feed cake-eating gremlins (obviously) that have access to the lockers through a rear door. We can assume E << L, and that some external entity is… — read more
