I use git via the terminal and not through UI tools (though I do use Sourcetree to understands the flow of commits), and I recently found a very helpful change for my prompt: It's turned out to be really helpful and not difficult to set...
At work, we use gerrit. It's different to git and to github, and we didn't get the right kind of training on howto use it. This is a self-assembled survival guide. If you can articulate the differences between a merge and a rebase then...
Clearly, the correct way to deal with dates in Java is with Joda, but I've been looking at a project which doesn't have Joda installed already, and I haven't earned the right to rearrange that project's dependencies and build patterns....
At work, we're in the process of moving datacentres and some of my (extensive) monitoring needs to be updated. In particular, I have a monitor on Hadoop jobs which looks for job names of a specific pattern and posts them to a TeamUp...
You're not going to want to do this - but if you have to do it ... I have a job that needs 200+ GB of disk to run. I have build servers which do have that kind of space, but as they are shared servers, other jobs can take some ...
I've created an new PGP key which you're most welcome to use. It's on the public PGP key servers, but it's also here, linked at the bottom of each page on this site, and below. It's only a 2k key, but should do for starters ...
It's been a year since my original Getting started with Pelican post and clearly I didn't write at all - why not? Part of it was that I'd little interesting to say, but part was that I had trouble with how I had Pelican set up and with ...
From https://www.grc.com/sn/sn-616.htm: PADRE: That's why there's only two drives, two types of drives I use in my NASes right now. One is Western Digital Red because that's got the TLER control, so you can essentially say, don't figure...
I had an itch to be able to easily find the Facebook ID for Place pages that I was visiting. You can - usually - find the ID that the Facebook Graph API uses for a Place page by looking into the HTML source of the Facebook Place page...
There's a lot of crap advice about getting jupyter notebooks to play nicely with pyspark. I guess things have changed a lot over the last couple of years, but here's how I have things. I use conda for my python envs, but I doubt that...
I have sensors - a great many - which report numbers daily. There's a long piepline and many processes between these sensorss and the ~daily reports I get, and sometimes weird spikes and dips happen in the numbers: often fixed the very...
Getting started with Pelican since I'd quite like to have somewhere that I can refer to. Why not use the automatic pages from GitHub? I don't know really - other than I'd quite like to do it myself and who know's how long GitHub pages...
We take quite a few photos and I'm forever reinventing how I look after them. Here's where I am at at the moment: Photos come from a few different cameras Aperture (now 3.2.4) is what we use to manage them All photos/videos are imported Good ...
I've been processing log files recently to see how a live system is being used. When you have millions of hits daily, you need these processors to be fast. Today the best way is to have your log files shipped over onto a Hadoop cluster...
One really quite useful command is “grep -o” - it allows you to fire off something like this: grep -o "Location supplier=\"\w*\"" locations.xml And the output will be the phrases matching the regular expressions that start with...
Thanks to http://www.contentwithstyle.co.uk/content/4-ssh-config-tips-for-faster-remote-working/ I can avoid creating files which need to be scp’d: I can pipe the content directly: local$ cat localfile.txt | ssh remote "cat - >>...
Here’s another view of the Places in the Nokia Places Registry. Each pixel is the location of one or more points of interest that we have as of the end of June 2011. Under each pixel there may only be one place or there may be thousands...
Here’s a little visualisation of what I am up to at Nokia. You see a KML representation of the Points of Interest we currently have - the taller the tower the more active places we have in that spatial area.
I am about to change some of my insulin settings, but before I do I thought I’d write them here. Below is a graph of how things are currently. As I am changing things you can deduce that the regime is not correct, but it isn’t too far ...
From listening to The Changelog for the first time today I should play with Yahoo’s YQL. It’s a server developer tool that allows you to query the web in a SQL-like format - and have the results come back in JSON. Where it gets really...
We have recently started to use TestNG and I like it. One thing that is needed is runtime control over whether or not to run a group of tests. We have both unit tests and integration tests to assure ourselves of the system’s health....
I keep loosing these links, so I thought I’d spend a minute and gather them here: http://jsonformatter.curiousconcept.com/ - really excellent http://chris.photobooks.com/json/default.htm...
It’s nice to be quoted - by J Chris Anderson at a Google tech talk last December. CouchDB: relaxing offline javascript 16:30 in is the start of my contribution
CouchDB needs to have it’s databases compacted regularly. It’s quite easy to do but the ease of doing so may lead you into thinking that it’s not worthy of serious consideration. You need to be aware of a few things. Here at the beeb we...
For a long set of reasons that I must sometime write about, I have a set of CouchDB databases which replicate with each other. Each database replicates with two others: one in the same datacentre, one in the other datacentre (we’re only...
On a server, we run 4 different CouchDB nodes, each with 30 or so databases. We can therefore have over 100 databases - and if you’re reading from large views - or view over large databases - you will need to do so serially. We have 4...
It's getting to be a wonder what's happening overnight. Here are some data points to ponder: 27th: 6.5@3:22, 3.6@7:02: is this down to one glass of wine last night? 26th: 19.6@3:35: was that me overdoing the recovery from a ...
The Accu-Chek Combo is an insulin pump that has the potential to make really important changes to how I manage my diabetes and therefore my live. It'll allow me to change how much insulin I get when and so better match my body's needs....
The BBC’s Forge engineering team uses an IRC channel to hold meetings. It allows our team to not bother about exactly where everyone is - some folks work from home, people are (mostly) in the office, but can be in different parts of our...
The 2009 CWE/SANS Top 25 Most Dangerous Programming Errors is a list of the most significant programming errors that can lead to serious software vulnerabilities. They occur frequently, are often easy to find, and easy to exploit. They...
You might want your stunnels to be running all the time - and to start automatically when you log in. Here’s how: get your stunnel working. You’ll need to fix your certs, choose the correct ports, and all that yourself. write a script...
