What about shipping sun.misc.Unsafe as 3rd party package? Is there anything in it that can't be done as through JNI?

Scala in Vim is quite workable - I will try the quickfix plug-in that I didn't knew about. Something that I find useful is proper ctags extraction for Scala, so here it is: https://github.com/luben/sctags I hope i

My guess is that it is something related the RAID handling in the block layer: I had a corruption on fat32 fs (/boot/efi partition) after upgrading grub-efi on my laptop. It sits on md-raid0 (intel fake raid) I also had multiple c

This is benchmarking Perl-5.8 that was already 3 years old in 2010. With Perl-5.10 there is an optimization for matching alternations (|) that should drastically change the results for the "URI|Email" pattern. In later versions of

Dynamically typed languages are not the best choice when you try to explain algebras that work on the type level I guess.

Actually yes - perl has a tainted mode (#!/usr/bin/perl -t) that force you to sanitize every input from the outside world. It does not do the work for you because it is agnostic to semantics (escaping for shell is different t

I was considering Go for some project of mine but the lack of generics turned me away because the project needed to do some heavy numeric computations over custom containers (sparse matrices). Now days I think that adding generics to Go wil

This is another evidence of how extensible and flexible is PostgreSQL. Great work!

That was also my first idea about solving it. No idea why they didn't took this route.

JavaScript is not homoiconic - JavaScript code could not be expressed as JavaScript data structure. That's the main point. If you could express your code as a data structure of the same language you can write programs to modify your pr

There is something similar in aws. The main difference is that it is distributed and can query and aggregate across clusters of thousands machines. Also I think it is not built on sqlite but implements new db engine.

I guess because of the learning curve - everybody already knows SQL and the time spent to create SQL parser is balanced by the time of thousands people not needing to learn some new (most of the time badly designed, look to example MongoDB)

Yes, you are right. This is true also for the "PostgreSQL" databases I mentioned - they use only the frontend of Postgres.

It looks most of the successful MPP analytic databases are based on PostgreSQL (e.g. Greenplum, Redshift). It's sad to see that InfiniDB could not make MySQL work for them reliably.

What is the reason for using product of all primitive types for boxing instead of tagged union?

by karavelov 12y ago
Unit type is completely different concept in the functional languages. It does not track units and measures.

I have no experience with PolarSSL but it is under GPL so unless your code is under GPL also it is a no-starter. I suppose this is a major obstacle for wider adoption.

1) I do not have experience with languages with heavy use of compound words so no suggestion from me. 2) There is a shared dict extension that load the dict only once. See: http://pgxn.org/dist/shared_ispell/ 3) A

In my regards it seems that one of their sources of inspiration were Transmeta processors - VLIW core, software translator from some intermediate bytecode (x86 in case of transmeta). I hope they will get it better this time.

I have experience with hundreds of T of data stores. My opinion is very high of Hitachi 1T and 3T Deskstars. The problem is that they are not generally available - there could be months when you just could not order them.

If you want to index on specific field with PostgreSQL you could use function indexes and bring the index size down
