Off to Hudl

After almost 10 years at Servelec-Corelogic I’ll be starting in a new position at Hudl on 1st June. I’m excited and nervous about the change and looking forward to meeting my new colleagues and learning about how they do things over there! Some of thethings to look forward to are their open-minded approach to technology, working culture and cutting edge continuous deployment processes. I’m sure I’ll learn a lot, and hopefully I can add some of my experiences to the team.

Some Thoughts on Almost 9 Years of Remote Working

Since I started working for Corelogic in 2005, I only spent the first year working in the office every day. I lived in London for that year, within walking distance of the office, in a nice, albeit small 1 bed flat. That flat probably cost around the same price as our4 bed semi in Nottinghamshire (and that was years ago). But I digress. Anyway, I didn’t enjoy living in London too much.

Sysdig - A general purpose system capture and analysis tool

I’ve just been looking at a nice new tool called sysdig, which seems to be really useful for analysing and troubleshooting on production systems. There’s a great blog post by Gianluca Borello, detailing how he set up a number of honey-pot servers with poor passwords, and then captured system activity with sysdig, showing exactly how his server was compromised, and what the hacker did at each stage. The level of detail he was able to garner is astounding, and I can see how powerful this tool could be in the future, for any sort of troubleshooting where it’s not clear exactly what has happened/is happening on a system.

Active Directory to OpenLDAP Sync with LSC

I have recently had to sync accounts and groups from Activc Directory to OpenLDAP, for a requirement for a directory server in the DMZ. A DMZ (De-millitarised zone) is an area of the network open to the internet. It’s supposed to be separate from the rest of your LAN, so you can have services running on the internet without fear that people can break into your LAN from these. There are other options for doing this, including a read-only domain controller (RODC), a AD LDS (Lighweight Directory Server) and so on, but they all require connectivity back from the DMZ to the LAN, which is precisely what we are trying to avoid.

HTTP 2.0 Is Coming

It’s been almost 15 years since the last standard of HTTP was ratified. HTTP is the protocol which transports web pages across the internet. It’s a brilliantly thought out and quite simple protocol. It’s beginning to show it’s age though, especially with the rise of many requests across multiple web servers. AJAX and newer technologies like WebSockets have worked around it’s limitations. It’s inefficient at connections, is designed to be stateless, so doesn’t maintain data in it’s headers between requests, and it’s not great at doing lots of requests in parallel.

Interesting Interview With Ladar Levison of Lavabit

An excellent and informing interview with the founder of the Lavabit email service, who was recently involved in a legal case with the FBI, who attempted to force him to hand over SSL encryption keys. This was of course the email service used by Edward Snowden, so attracted a lot of attention. There’s some really interesting technical stuff in here, specifically about the value of perfect forward secrecy in HTTPS encryption, which he wasn’t using, and how he protected his user’s data, in many clever ways.
