Cool. Of course, the is-modified flags don't do much for large, idiomatic Ruby applications. As soon as anyone modifies Object, Class, or Fixnum (as seen in Rails), it goes right back to slow dispatch mode, which is why invokedynamic is so

Type annotation wouldn't do much for Ruby honestly. Most idiomatic Ruby code (i.e. loading Rails into the object space at all) would break any optimization type annotation would yield. There's no compiler, so guards would have to be inserte

JRuby generates direct, "static" dispatches to the Fixnum class when you throw the --fast flag. However, this is not backwards compatible with MRI Ruby, so it's not default. Clojure does not attempt to maintain compatibility with anything,

I love your commitment to purity here. Things could certainly be made much faster in Ruby if most of what makes it useful in certain contexts were abandoned. The complexity of invocation alone seems to be fairly unique with the potentially

If you're mostly K=>V and you want distributed, why not look into Riak? It's really easy to administer and has very nice operational characteristics.

Unfortunate to see it still has the global lock pair and lack of online compaction.

At current RAM prices, one can build a cheap 2U SuperServer with 144GB of ECC DDR3 1333MHz RAM, a single quad-core 40W 2.13GHz Westmere processor, a 10gig-E card, and a 4GB CompactFlash drive for ~$4,000. Assuming the server has a 3-year li

Perhaps they are scanner & printer drivers, the implementation exposes a ScannerDriver interface and a PrinterDriver interfaces. They subclass a DeviceDriver that implements the low-level I/O. There are other generic and vendor-specific

... which is why it's inappropriate for a desktop backup solution. The chances of simultaneously losing your hard drive AND the entire RAID array in the Backblaze container that stores your data are so small that it's not worth paying extra

Agreed, the value add isn't very high, especially since the pricing is higher than EC2. Surely there are some economies that could be found on servers with no disks and reduced CPU requirements? I wonder if ECC could even be done away with

Going to be pedantic and say that the NoSQL section is a bit off saying Dynamo-like systems "shard." This carries with it the connotation that the distributed aspects of the database are an afterthought or an add-on feature.

Welfare recipients still pay sales & use tax as well as property taxes (either directly or indirectly via rent payments).

In summary: lower & middle class people don't like it when those living in poverty are recipients of social welfare because it makes them feel as if they are socially equal to those welfare recipients. This is an interesting hypothesis.

I think for tooling around in SF on mostly 1-2 mile rides with lots of stop and go, the advice works well, but that's not what I can give advice on. For the 10-mile-one-way mostly suburban regular commutes I used to ride, I second the road

This fails at the most basic benchmark rules. Do you really think PostgreSQL is 20-40x slower than alternative implementations? Do you think that is reasonable? I'm going to go ahead and assume (as with most benchmarks) that the PostgreSQL

MySQL cares about data reliability? Maybe if you spend much time agonizing over the configuration and set it to strict mode.

Not just that, but getting a deep understanding of how the RDBMS (or NoSQL solutions, for that matter) implements the database is important as well is very important. It requires a low level understanding of how the implementations write th

This is exactly the problem with MongoDB. It's practical use is a semi-durable, in-memory data store, but they advertise it as a data store of record that can be used for large, >RAM sets of any conceivable use case.

As far as I know, PHP is the only major programming language that considers itself a "web programming language."

Yeah, clearly this is a troll blog. Congrats to the troll.

So again, to you, what benefit does everything being built on this async, single-threaded, event-driven model give you? Sounds like not much. You could get all of those benefits + much cleaner code using threading or fibers or actors, but t

I'll definitely admit that many of the inventive techniques that node.js users have come up with make dealing with callbacks less absurd, but the problem is that it's just polishing shit. It's extra hoops to jump through with no benefit, ou

Actually, "deal with it" is fucking lame, isn't a response at all, and is a good example of why I use the term "fundamentalism." Is your problem with threads or shared mutable state? Web applications should be stateless and can be written a

Huh? how does any of this keep me from having to write callback spaghetti? If I send a call using redis or dnode or whatever, I have to wait for it, so that means a callback. I feel you about the polyglot and tend to agree, but I think some

This purist evented I/O fundamentalism has to stop. While evented I/O is great for a certain class of problems: building network servers that move bits around in memory and across network pipes at both ends of a logic sandwich, it is a tota

If this does happen, I see it mostly as important for XBMC-type setups on Linux.
