It's mostly annoying in development when your mid-large Rails app takes 30s-2m to start-up and/or reload after an edit.

To be honest, this sounds like a perfectly normal contract. The larger company quite reasonably wants not to have the employees of its 19 acquisitions to each all have completely different paperwork. Personally, I find that the easiest way

Your phone runs a bunch of proprietary stuff that I as a hacker don't want. Additionally, it doesn't have (enough) USB ports, HDMI, a bunch of pinouts, ethernet, PWM, etc. http://www.ubuntu.com/phone plus an opti

It's probably fully-loaded cost, so salary is 50-75% of that, but yes, doing a temporary and undesirable job for a large company in some remote barren location generally pays well.

Our production thrift code generator (now at https://github.com/twitter/scrooge ) was JRuby for about a year, before Robey decided it was an abomination and rewrote it in scala. JRuby was easy because you can Maven requ

Large queues can have problems. Perhaps your queue is effectively 30 seconds deep at times. But your clients time out around 10 seconds. Now every request in the queue is useless. If your clients retry, then now you have a feedback loop

Typically, you cache the last write somewhere close so that you can manually splice it into the corresponding page render. Then you engineer the rest of the system such that the log processing system is rarely/never falling behind.

There's at least four mathematical representations of QM, ascribed to Shrödinger, Heisenberg, Dirac, and Bohm respectively, which are all mathematically equivalent. So you aren't really going to disprove only the Bohm picture, b

I'm going to try to explain this in programming terms :) There's a longstanding interpretation that the wave-particle duality is actually caused by (e.g. electrons) being particles riding invisible waves. This interpretation (Boh

It's very hard to ELI5 quantum mechanics. The only thing we can definitively constructively say is that we have a mathematical system that describes the universe very well at certain time/energy/distance scales. Trying to a

Look into quadratic voting ( http://ericposner.com/quadratic-voting/ ) as a solution to e.g. the gay marriage problem.

You'd implement the merkle trees yourself in the application layer. Alternately, you could use hash lists. It'd be somewhat similar to how you'd implement geohashing. Let's say you just take a SHA-X of each row repres

A logical "SELECT COUNT(*) WHERE updated_at < now()" is probably reasonably fast on your primary store and ElasticSearch.

The Lucene team has been promising an end to corruption since the 2.9 days and before (~10 years). If you believe them that the problems are all fixed, and you need to be serious about it, I'd wait more than a month before declaring t

Given that this is based on Elasticsearch, there will be a master node, which should be chosen explicitly in configuration to be away from the data nodes, because ES responds poorly to garbage collection on the master node. So you want to

I think you could, but at this point you're butting up against the event loop assumption: that most of the work is IO. If you do compute on the edges, you then want threads, and you're re-engineering redis (Edit: I should have re

What you're hoping for is that some cacheable function of many documents is also a monoid. In an example, you're hoping that when you invalidate the query "SELECT COUNT(*) FROM foo WHERE x = 1" because a new document tha
