The Saga of Gill-Hank

Imagine, if you will, that you have arrived at a large and reasonably luxurious hotel, with a heavy bag in tow. The bag is not too much of a nuisance, it has wheels and so you can drag it along, but you sure wouldn’t want to have to carry it upstairs. You check in with […]

Phun with PHEV

Well, that escalated quickly. We went from thinking in November/December that we needed a solution for carrying more kit around than would fit in the Panda, to driving away from Portsmouth on 11th March in a brand-new Mitsubishi Outlander PHEV, paid in full (mostly from some money I had sitting in Australia, hoping the $AUD […]

A man is not dead while his name is still spoken.

Something I have been meaning to do for quite a time is to take up the idea of keeping PTerry’s name alive by adding the X-Clacks-Overhead header to parts of this site. Even if it is only in the overhead: GNU Terry Pratchett.

Maven releases with Git

I’ve started to put various snippets of code up into GitHub, partly because they may be useful to other people, partly so that they are more accessible when I do not have my personal laptop with me. Yes, Virginia, I could put it all on a USB stick (and I probably will), but that poses […]

CSS3 Oops.

Revising my resumé as part of an overall overhaul of my site, I realised that the presentation on mobile devices was not very good. Fortunately since I last did anything major, CSS3 has become widely implemented, so Media Queries are now an option for degrading onto smaller screens. To my pleasure it did (eventually) just […]

Robots. They are coming to take your content.

I am in the process of revising my site, and discovered for whatever reason that I had an empty robots.txt file present. I know it is only a voluntary ‘standard’, but as far as I know all the major players do respect it. As the overwhelming proportion of users use a search engine that respects […]

(Mobile) Weapons of Choice

Like any other code-worrier, I have a ton of applications on my (i)Phone, ranging from “things that look shiny but are useless”, through “things that I use once a year”, up to “indispensable and every-day”. Out of interest I’ve tried to work out what apps are the once that fall into the latter category, apps […]

ORM?

It’s rather annoying that in 2015 the ORM (Object-Relational-Mapping) problem is still tedious to deal with. While in general terms it is a solved problem – JPA and Hibernate and similar frameworks do the heavy lifting of doing the SQL queries for you and getting stuff in and out of the JDBC transport objects – […]

Doing More With Less (Part 1 of N)

In recent weeks I have been massively overhauling the monitoring and alerting infrastructure. Most of the low-level box checks are easily handled by CloudWatch, and some of the more sophisticated trip-wires can be handled by looking for patterns in our logs, collated by LogStash and exported to Loggly. In either case, I have trip wires […]

Elephants and Pigs

Since I did have HomeBrew installed, I went ahead with this set of instructions, with some variation. Note that at the time I did this HomeBrew installed Hadoop 2.6.0, not 2.4.x as described at this site: https://www.getblueshift.com/setting-up-hadoop-2-4-and-pig-0-12-on-osx-locally/ I had previously verified that I could ssh to my localhost, so skipped over that, and went straight […]
