We normally meet every second Tuesday of the month for talks and demonstrations from 7:00pm onwards at BCB Radio in February, May, August and November and online in other months.
Why not come along to a meeting?
Until the start of the pandemic in 2020, some of us used to create IT Stuff for BCB Radio (106.6 FM). Shi has looked back on this for us.
Alice started us off with Optimising Impala Queries, or a ‘Distributed Lego Community’, a demonstration of the principles behind Parquet, a columnar storage format, and Impala, an analytic database, for the Hadoop ecosystem. Columnar storage formats overcome the burden of reading every row of a table based database such as SQL.
With no presentations prepared, we talked about this and that, from Elixir, a concurrent programming language that runs on Erlang, to openSPARC.
Brian introduced us to the Pine 64, an expandable single board computer starting at $15 for 512MB. Though a 2GB version was advertised, it appeared that only the 512MB and 1GB versions are currently available.
Stephane then recommended the Charbax videos and in particular the interview with Bernhard Rosenkränzer on the Android team at Linaro and Rob Clark of Red Hat who works on the open source GPU driver called Freedreno for Qualcomm’s ARM processors’ Adreno GPU. He noted that ARM GPUs are all bound to specific implementations of the GPU which makes producing common code very difficult.
John H began with a presentation on the background to the recent release of openSUSE LEAP 42.1.
Alice then demonstrated using the Realtime Trains API to download and analyse information about train movements on Train workings; the source code is on GitHub.
John H described the work he was doing on the Heath Old Boys Association website; this was a 2003 vintage frame based website which did not play well with modern devices; after he had explored various options, he had decided that the best option was to build a new HTML5 website on the lines described by Dave Fisher in his 2010 talk to BradLUG in front of the old website so that people could continue to access the old website while the new one was under construction.
A select group of members gathered to celebrate the seventh birthday of BradLUG; there was cake and then John H presented a review of our seventh year which provoked a lot of discussion ...
For the first time ever, no-one had come prepared with anything. So we welcomed Brian from Spain, talked about youtube-dl and get_iplayer and watched the Stephen Bourne lecture about the Early days of Unix and the design of sh.
John drew attention to the recent change in the MariaDB 10 .mysql_history
file format which means that any old .mysql_history
file is overwritten [he later found the following thread in the RedHat Bugzilla which suggests that the issue has been around for a while but is only cropping up as distros update to MariaDB 10].
There comes a time when small charities begin to think about a website. You need four things for a website:
Mailing List
The mailing list is kept up to date with all the details about the meetings, socials, ideas, and questions.
