Stuff that can’t get stuffed in other cats.

Preventing WordPress BFL/DDOS attacks

I host a lot of WordPress sites and a common problem is the Brute Force Login attack, which could also be classed as a DDOS attack as it can overload the server or drive MySQL beyond it’s limits. I’ve taken to using an .htaccess¬†section to mitigate this and it’s quite successful so far, although with some small limitations. Continue reading Preventing WordPress BFL/DDOS attacks

A new dual sim smartphone: Xiaomi Hungmi

I travel a lot and it’s always a hassle changing out the SIMs whenever I need to check for calls and messages. A friend of mine, in a similar situation, brought a nice dual HTC SIM phone although he had to order it from Dubhai and it was ¬£500. That’s a bit steep I thought… and decided to see what else might be available in my price bracket.

Searching for a new CMS

There are a couple of new projects coming up and I want to find a simple CMS for them. Both projects will need a user interface that is very simple and easy to use and the sites are basic enough that I don’t need a lot of bells and whistles. It needs to have the following; a simple user interface for entering and changing entries, simple API so that I can add in some custom stuff, self hosted, good documentation and strong community.

A Fallow Year

The fields awaken as the snow disappears.

I was travelling through Czech with a friend a couple of weeks ago. The fields were just seeing the light of day after a winter under the snow, the colors that greenish yellow of vegetation that hasn’t seen sun in a long time, the ground bare in patches. What do they grow here? I asked. I don’t know, he answered. Sometimes they leave the fields empty for a year so that they can regenerate, how do you call that? A fallow year I said.

Ubuntu on a Lenovo ThinkServer – NOT!

I’ve spent a frustrating day trying to install Ubuntu 11.10 on a Lenovo ThinkServer TS130 with RAID. I was trying to install using software RAID and so far I’ve run about 10 installations, with no luck. Installation works fine, Ubuntu is very happy, all the checkboxes ticked until it says installation is over, time to reboot. And then on reboot the BIOS gives me an “Error 1926: no operating system found” or similar. Searches on the ‘net gives some clues that it is something to do with Lenovo having a buggy EFI implementation and Ubuntu not working well with GBT , but there is nothing definite.

So, eventually, I gave up, downloaded CentOS 6.2, ran a new install and we’re up and running, with updates, in short order.

These notes are for those of you searching for the same issues as I was and finding a shortage of information.

Finding a Xen server

For various reasons, I have a customer that would like to try out a Xen virtualization server. Not a big one, more of a test bed for some ideas and also a chance to experience how Xen is to work with. I’m happy to help, I’ve just finished setting up a VMWare ESXi system for a company and that was fun and exciting. Virtualization is the way to go. Anyway, I took a look around for some providers of small size solutions, here are some notes:

A Search for Online Storage

I spent the evening looking for some online storage. I currently make use of spare disk space on the hosting servers (for client storage) and Amazon S3 for backups (using Duplicity). Amazon is great for having one, unlimited account where I can back almost anything up, but it’s not so useful for clients as they need to have a login to up- and down-load files. And using space on the hosting servers has got to be about the most expensive way of handling storage needs. Time to check out some alternatives… Continue reading A Search for Online Storage

Installing Lightning on Thunderbird with x86_64 systems (updated)

Thunderbird is one excellent mail client and sometimes it would be useful to have, at least, a look up into a calendar or such like. Mostly I like programs to do one thing and do it well, so an email client would handle email and a calendar would handle dates and appointments. But Thunderbird does have a plugin that handles calendar functionality and makes use of the Sunbird calendars so giving the option of using Sunbird or of using Lightning. There is just one small problem: I run 64 bit Thunderbird on a 64 bit system, and Lightning is only packaged for 32 bit.

viral videos

I was just renewing a domain at (a large UK registrar) and after the process followed a link to the “Top 10 sites at Easily”. Number 3 was a site, which seemed a little bit odd unless the British have got a taste for animal (or crowd) control. You can discover the site for yourself, but from a technical standpoint, it’s an excellent use of Flash and from a personal point of view, I’ve just wasted an hour there…
