While most things were fairly trivial to sort out, we hit one less obvious (and pretty critical) bug during the migration surrounding django-bcrypt. This bug would only present itself if you’ve transitioned from … David Cramer http://justcramer.com/ 2013-02-27T00:06:00-08:00 http://justcramer.com/2013/02/27/a-weekend-in-russia This past weekend I had the opportunity to attend Russia’s first ever PyCon. If you’re not familiar, PyCon is the name used for several Python programming conferences. The event itself was set at a holiday lodge in Yekaterinburg and had somewhere between 200 and 300 attendees. It&#8217 … David Cramer http://justcramer.com/ 2012-08-30T20:59:00-07:00 http://justcramer.com/2012/08/30/how-noops-works-for-sentry Update: Don’t decide against Heroku just because you’ve read my blog. It makes some things (especially prototyping) very easy, and with certain kinds of applications it can work very well. I’ve talked a lot about how I run getsentry.com, mostly with my experiences on Heroku and … David Cramer http://justcramer.com/ 2012-06-03T17:53:00-07:00 http://justcramer.com/2012/06/03/scaling-your-clouds My post yesterday seems to have gotten all the cloud fanboy’s panties into a twist, so I figured I’d give them something else to rage about. There were lots of claims that without the cloud you can’t scale, or you dont have redundancy, or you can’t come up with the result … David Cramer http://justcramer.com/ 2012-06-02T13:57:00-07:00 http://justcramer.com/2012/06/02/the-cloud-is-not-for-you Update: Did I hurt your feelings with this post? Read Scaling your Clouds so you can rage even more. Well, maybe not specifically you, but the mass that screams it will solve their problems. It’s been a fun year so far. There’s been exciting things happening both for me personally, as … David Cramer http://justcramer.com/ 2012-05-04T15:12:00-07:00 http://justcramer.com/2012/05/04/distributing-work-without-celery We’ve been migrating a lot of data to various places lately at DISQUS. These generally have been things like running consistancy checks on our PostgreSQL shards, or creating a new system which requires a certain form of denormalized data. It usually involves iterating through the results of … David Cramer http://justcramer.com/ 2012-05-03T11:13:00-07:00 http://justcramer.com/2012/05/03/using-travis-ci I’ve been using Travis-CI for a while now. Both my personal projects, and even several of the libraries we maintain at DISQUS rely on it for Continuous Integration. I figured it was about time to confess my undenying love for Travis, and throw up some notes about the defaults we use in our … David Cramer http://justcramer.com/ 2012-04-24T22:23:00-07:00 http://justcramer.com/2012/04/24/sticking-with-standards More and more I’m seeing the “requirements.txt pattern” come up. This generally refers to projects (but not just), and seems to have started around the same time as Heroku adopting Python. I feel like this is something that matters in the Python world, and because I have an … David Cramer http://justcramer.com/ 2012-04-08T16:52:00-07:00 http://justcramer.com/2012/04/08/using-arrays-as-materialized-paths-in-postgres Something we’ve been casually working on at Disqus for quite some time is an improved pagination method for threaded comments. This is obviously pretty important to us, it drives the very foundation of our product. It also happens to be an area that’s somewhat challenging, and has a … David Cramer http://justcramer.com/ 2011-11-10T16:06:00-08:00 http://justcramer.com/2011/11/10/scaling-schema-changes I frequently get asked how Disqus deals with schema changes. It’s a fair question, since we operate a fairly large amount of servers, but I also tend to think the answer is somewhat obvious. So let’s start with the problem of schema changes at scale (in PostgreSQL). Generally you have … David Cramer http://justcramer.com/
