The language (and the features) presented in this presentation are from Fortress, which Guy and other Sun researchers have worked on for some time. On the project page one can download Fortress 1.0 and also check out Fortress 1.0 specificat

Slide 34 where you find out that the improvement was only a little better. 03.hs is a fairly simple program and I would guess that one would run into a lot of these problems developing "real programs". I would prefer if the compiler / runti

It looks like the speed gains are rather small and optimizations complex to debug even for small programs. And the "implicit parallelism" is really an explicit one since you have to annotate/hint what could be run in parallel.

I have also used this method for some time. An advantage the author does not mention is that this method is required if you want to host your files on a CDN like Amazon's CloudFront. Another point is that you should host your CSS and image

It was developed by @mitsuhiko and it has taken some work (you can check out the source code on http://bitbucket.org/plurk/solace/src/tip/solace/ - it's not a simple project). That said, it has not taken a lot of time, because mitsuhiko i

The Wikiepdia page explains a lot more about what Terracotta is: http://en.wikipedia.org/wiki/Terracotta_Cluster - and no, it's not a replacement for a RDBMS :-/ Flagged the article for really crappy content.

People that find code.interact useful should check out IPython* (which is an interactive Python shell with auto completion and a lot of other features). Here is how I launch a shell for my projects (it tries to use IPython, if it isn't work

I think this would be a good philosophy to apply on features (i.e. add only a feature if it's a "hell yeah", otherwise don't add it). The problem with this philosophy is that it can be hard to know what features users are interested in, so

I have been a hardcore Vi(m) user for the past many years. Over the years I have learnt the mastery of Vi editing and I love editing in Vi. But one thing is for sure: Vim (at least for Mac) sucks badly. The scripting language is a joke, the

I am looking forward for Fortress 1), which takes these ideas to the extreme (basically, the whole language is unicoded and the syntax is mathematical). Fortress also features some very innovative features such as implicit parallelism for a

It feels a lot faster, at least on Mac OS X. The interface seems to be much more responsive as well. It's nice to see they have focused on performance :)

I have had similar issues like you (i.e. very poor performance of Berkley DB, especially under load). I am sure thought one can configure this (some options are listed here: http://www.oracle.com/technology/documentation/berkeley-db/d...

50% faster on a long running for loop is not the same as 50% faster baseline from CPython... At least from my knowledge PyPy's RPython is not faster than CPython.

I think providing useful stack traces is one of the most important features of a language - since it makes debugging so much easier. Those languages that have great stack traces are Java, Python, Ruby etc. Some languages that have pretty cr

I don't think things win market share by how cool or powerful they are - e.g. Betamax vs. VHS OR SPARC vs. x86 OR Haskell vs. C. Why something becomes popular has to do a lot with timing, price and creating something that's "good enough". O

That's actually untrue. If you look in the implementation of the `re` module you would see that it caches the compilation of any regular expression.

I have often wondered why not use a MySQL table as a "queue" (or more tables if needed). Basically, you get great performance (MySQL is really fast), you get great language support (a LOT of languages can add tasks via simple SQL) and you

So far at Plurk we have struggled to overcome scalability issues - - and none of them are due to Python, even thought we use Python a lot. Most of the problems we have seen have been related to the database. It was and still is the biggest

It's stated that scrypt is 4000 times harder to break than Bcrypt (I don't know how this is calculated, so it's probably an estimate). Given that password cracking can be easily parallelized is this enough of an improvement?
