Cool things I have worked on: Clustered analytic database (by alaric)

In my last blog post, I talked about how I was involved in building a database optimised for low latency on single-record reads.

So it was a bit of a change to later work on a database optimised for high throughput on bulk querying! Rather than getting single records, it was all about finding all the records that match some criterion and doing something with them as fast as possible, where "fast" is measured in "records per second". When I started there, the minimum time to perform a trivial query (eg, SELECT 1) was about three seconds, let alone any that fetched any data. However, on the right hardware, it could process untold numbers of gigabytes of data per second once it had gotten going. That three-second minimal round trip time was negligible when dealing with queries that processed hundreds of terabytes of data in ten minutes. That said, one of my first projects was to fix some low-hanging fruit, which brought the minimal round trip time down to around 300 milliseconds. Read more »

The Hackspace Grand Opening (by sarah)

Those of you who follow me on various social media will have seen the photos of Cheltenham Hackspace new premises being spruced up and that is because tomorrow (well today now!) is the grand opening 😀

Sunday 4th of December - if you are local then please pop along - hackspaces or createspaces are made by and for the community and we'd love to meet you 🙂

I'll be taking along steam punk and textile stuff to be working on and have plenty of spare so others can have a go! There is plenty to see and people to talk to and skill share with 🙂

Also I have been making craft videos for Advent as it turns out it is the tenth Christmas of Salaric Crafts How To Blog!!!

Of course I only have 2 vids up and it is now technically day 4 - annoyingly obsolete laptop is obsolete and is being a pain in the backside but I shall continue limping along with it and hopefully get the other two vids to you some time tomorrow!

I also have a craft fayre Monday at the Costa Coffee on Metz Way in Gloucester 🙂 Mainly taking Wiggly Pet Press stuff with a bit of Steam Punk etc...
