My interpretation: Firstly, inlining has nothing to do with state mutation. He just happens to be talking about a codebase that does a lot of state mutation - eg. a video game. Therefore the functions he's talking about inlining are st

Totally agree that would've likely worked too, though I'm not convinced it would have been significantly faster doing a dump, import, and data processing. Dumps from mongo typically took upwards of two hours not to mention transfe

Would honestly be great to know about, but how do you raw copy a nested mongo document? The big hurdle was the lack of 1-to-1 mapping between primitive types in the databases.

To answer your question - we were rebuilding the app and in the process moving from Rackspace into AWS. We wanted to use as many amazon managed services as possible since we don't have a huge team. PostgreSQL seemed like a nice managed

This is great! Appreciate the tip

This would have been great, but the lack of a 1-to-1 mapping between data models complicated this. To migrate a single "record" required several queries in the old database, some restructuring, and then several inserts into the ne

It was actually a combination of several queries in the first database followed by several inserts into postgresql.

Knowing the author personally and having worked at the same company with him (he left there a long time ago). I can say it is neither. It was among the most broken places I've worked. The author himself is a great communicator and tech

There is really and truly a problem. I've worked full-time for several start-ups (I'm working full-time for one now) as well as consulted for several more. I've also networked with a lot of startup founders and know many othe

You'll get no argument from me here. Cassandra + Hadoop only make sense at a certain scale.
164.
by zenogais 12y ago
This actually sounds like a great fit for Cassandra and Hadoop. You could use Cassandra's built in TimeUUID as the primary key and have your data pre-sorted on disk in time-series. This would make big queries, using something like Hado

I think looking at it as pessimistic is simply wrong. The point is not to be optimistic but to look around and explain the major challenges that seem to be impeding rapid advancement. The biggest problem I see in science seems to be the inc

People right now all over the world and in the US are already being asked to sacrifice their well-being and lives for pursuits most of them find utterly meaningless[1]. In addition many of the millenial generation are already crippled by de

Totally agree. My 2 additional cents. Most reasonably skilled programmers can read code. They choose not to. Cultural problem not technical one. I've been in the industry a long time and the best codebases I've seen had a handful

Fascinating view of yet another high-profile software project failure. Also a demonstration of the consequences of not making getting software development right a priority.

That same flippant attitude might be why the output of his employees is less than stellar. Chances are respectful leadership is absent at whatever company this is.

I was gonna try, but it's a lot of work to even begin deconstructing all the parts of this that are simply incorrect or ahistorical.

I think that even more important is that this provides an explanation for the obsession with getting less sleep that seems particularly pernicious in start-up culture, but is noticeable elsewhere as well. It goes beyond merely worrying abou

There is no "anti-capitalist bogeyman", not even really sure what such a phrase means. Certainly to ignore capitalism in a critique of present conditions is to miss the facts that capitalism is (A) A fairly recent re-organization

The author may not be very knowledgeable on this front. Fortunately, there are many economists all over the world working on exactly this idea. A basic income would not mean dismantling SS as Americans don't have Universal free healthc
