You don't have to be FB-scale to need something capable of handling a larger amount of timeseries data than postgresql can handle efficiently. 100 servers each producing 100 stats tagged 15 different ways aggregated into avg/50th&

Some people literally get joy out of using things that are well designed and don't feel cheap. When it is a device you are going to use constantly for work and other things then it becomes very easy to justify buying a "luxury&quo

Equational reasoning like it is presented in the paper is alive and well in the Haskell community.

The issue with that is that you have to trust the archive now as well.

Other than the examples, what kinds of interesting things could this be used for? What are the advantages over writing code for the coordination?

It seems like the latest generations of software developers (which includes myself) is hazardously opposed to spending money on software, even when it can save/make you huge amounts of time and money. I was lucky in that my first job w

What is confusing about this licensing? Previously it was a mess and prohibited our use case, but this looks pretty straightforward.

DISCLAIMER: I don't necessarily think the types of regulations proposed are the answer, but at the very least there should be some responsibility on people using high-bandwidth connections. It would probably have to be legally mandated

You don't think ICU nurses or PAs (especially at big hospitals) have a comparable work environment?

Favoritism? It is a lot easier to vet someone you have worked with extensively, or if someone you trust gives a recommendation. It isn't like there is some secret society -- it is simply the way the world works. Those are extra bits of

How is it a conflict of interest? They are all interested in making money... It isn't like he was a public official and decided he was going to give himself tax money. It is also a private company and can do what it wants in this regar

The Algorithm Design Manual by Steven Skiena Really enjoyed that book! It intersperses real world use cases which helps when your motivation starts to wane and has a warmer tone than most algorithm books. That being said, it is still pretty

Yeah, that is what it seems like. Using a column store and doing a bunch of pre-aggregation is the only way we've been able to to come close to these requirements, but I keep hoping there is a system that will do what we've done w

How fast are group bys? Like say I have 120 billion rows, 25 not-sparse columns, and want to group by between 2-20 columns (5 of which are varchar), aggregating the other 5 columns? What kind of hardware would I need to do that interactivel

I don't understand how you calculated how much it costs to compute on the Redshift cluster. $1100 would be ~28 hours of the 8-node cluster.

> and a DC1.8XL costs $4800/hour to "compute" the data. Is this a typo? A single DC1.8XL is $4.80/hour. 8, like the article, would be $38.40/hour.

Yeah, thats about a half hour of down time for every AWS East based company... who knows how much lost revenue -- and yet they just say the service is green with a little info tag. If our service is down for any customer (much less an entir

Even though their status page says everything is basically fine -- oh just a blip with API dns this morning no biggie -- they have had major problems today too. Like, can't connect to dynamodb, sqs, kinesis. Unfortunately they lie thro

Yeah, that is definitely possible. I mean, hopefully it is over HTTPS so they can't do anything with it... but if it isn't then it can definitely happen. Our servers get random web traffic all of the time.

I was surprised to hear that RethinkDB was shutting down, since everyone that used it seemed to like it. I looked into their business model a bit more... and it was like, super difficult to figure out how to actually pay them for anything.

What amount of data are you ingesting per day and what is the cost? How much time do you spend maintaining Druid? Do you have dedicated SRE/devops people managing it or is it something a dev could do with minimal time investment? Answe

Spacemacs fixes a lot of the discoverability problems of Emacs and is generally more ergonomic. I don't know anyone that learned it as a first editor (everyone already knew vim or emacs) but it seems like it could be a much better expe

"Implementation detail" We are in strong disagreement about what constitutes an "implementation detail". But also, you can just use a monad transformer stack and add whatever side-effectful operations you want into it, u

You can achieve this level of control using monad transformers or extensible effects -- this is a standard technique in Haskell. frignate :: (MonadDB m) => Config -> m Int frignate cfg = do db <- getDB ...

Even at therapeutic doses it can be psychologically addictive.

I wish there was more information on how much work it takes to maintain a DC/OS setup. All the marketing makes it out to be the easiest thing in the world.

This would be great, but I don't think it works on AWS -- I don't think they support broadcast.
