Lunchtime Hack: Decoding LocationHistory

James Uther wrote “Last month we took a look at how we might get our location history from Google and show it on a map. We found that the real deal is found at Takeout and consists of a file that’s mostly an array of lat/lng/time entries, but with some sort of ‘activities’ sub-elements sometimes. After a quick…”


(defn reloaded/-main [] …)

Ceri Storey wrote “I’ve been using Stuart Sierra’s reloaded pattern on a few Clojure projects recently, and I hit upon the problem of how best to use Stuart Sierra’s reloaded with a typical long running application. So, I thought I’d share one possible solution. Most of the code should be self explanatory, but there are a few things…”

Java multi methods new home

David Ireland wrote “I’ve split Java multi-methods out of LShift’s Java library. That’s mostly because Guava has equivalents for just about everything else in the library, but the multi-methods part is still unique, as far as I’m aware. You can find it here. You can raise tickets there as well. For more information, see the original post. Here’s…”


Internship at LShift

Elzbieta Siwy wrote “Introduction Today it’s my last day of a 5 month internship as a Software Engineer at LShift. This has been a truly valuable experience for me. I am a third year student of Mathematics and Computer Science at Imperial College London and working here has taught me skills I would have not gained by just…”


Lunchtime hack: My cycling routes

James Uther wrote “Like most Android users (because I think it’s the default) Google tracks my location. Thankfully, they provide a way for me to view and edit the data collected (Thus satisfying some major rules of personal data collection – well done!). But the interface on location history is clunky as a visualisation, so let’s spend lunch…”

Optimizing Salsa20 in BouncyCastle

Jarek Siembida wrote “A while ago I started dabbling in cryptography a bit, and inevitably, I ended up toying with performance of the related algorithms and code. In this post I’d like to share my approach to optimizing BouncyCastle’s implementation of Salsa20. A few observations regarding Salsa20 (and presumably other modern ciphers) in the context of performance: Salsa20…”

Automating pre-deployment sanity checks with Grunt

Sam Carr wrote “Grunt is a great tool for building, running and deploying ‘Single Page Apps’. I have a single grunt command to build and deploy to S3 for production, but recently I added some extra functionality to make deployment safer and even easier: Abort if you are not on master branch Abort if there are any uncommitted…”

Things I wish I’d known about Google Docs

Sam Carr wrote “I have had cause to write a lot of Google Docs recently, which leaves me furnished with a stock of interesting observations that others might find helpful. With no further ado… It doesn’t auto-number headers I typically want my business-like docs to have numbered headings, so an H3 might be “2.4.1. Architecture considerations”. Word can…”

Optimising compilers as adversaries

Ashley Hewson wrote “Suppose that you want to handle some secret data in C and, in the wake of some high-profile vulnerability or other, want to take precautions against your secret being leaked. Perhaps you’d write something along these lines: #include <string .h> typedef struct {   char password[16]; } secret_t; void get_secret(secret_t* secret); void use_secret(secret_t* secret); void…”


Dockerising an XMPP Server

Shaun Taheri wrote “As part of an internal migration of our XMPP server, we thought this would also present a good opportunity to test drive Docker to see if it would be useful for other infrastructure projects in the future. Docker is fast becoming the industry standard for deployment on Linux platforms, and for a number of good…”
