This version introduces parallelized encryption and decryption on multi-core processors (or multi-processor systems). Increase in encryption/decryption speed is directly proportional to the number of cores and/or processors. For example, on a quad-core processor, encryption and decryption is four times faster than on a single-core processor with equivalent specifications

Don't confuse gratis with software freedom.

It should be clear that when Truecrypt.org talks about Truecrypt being "free and open source" they mean gratis, free as in zero price.

Also, two questions: Does section III.1.d. of their license forbid commercial distribution of any Truecrypt derivative?

Section VI.2. looks like it tries to take away rights your region grants—"YOU MAY NOT USE, MODIFY, COPY, CREATE DERIVATIVE WORKS OF, (RE)DISTRIBUTE, OR SUBLICENSE THIS PRODUCT, OR PORTION(S) THEREOF, EXCEPT AS EXPRESSLY PROVIDED IN THIS LICENSE (EVEN IF APPLICABLE LAW GIVES YOU MORE RIGHTS)." where infringement is punished by termination of what rights the license grants; is that correct?

I'm not convinced that Truecrypt would qualify as a free software license. Whether it qualifies as an open source license I leave to those who follow that movement.

TrueCrypt License Version 2.5 is Acceptably Free

The bit you have quoted is from TrueCrypt License Version 2.5. This section by it self would make this licence non-free. Together with the rest of the TrueCrypt License Version 2.5, licensees have adequate right to their essential freedoms. This licence is a strong copyleft licence. The implication of this specific licence is that it is a usage, modification and distribution licence; you only get to practise your essential freedoms as long as you comply with the licence.

While this specific licence is fairly complex compared to other copyleft licences, all the requirements are workable and fair. This has my personal approval. Of course, you should not just take my word for it and get your own legal counsel to help you interpret these matters.

I haven't looked into the restrictions of their licensing, but its certainly free software, hence listing it here.

It does not seem to be free as in freedom

From their licence (Section III, 1.c)

'Phrase "Based on TrueCrypt, freely available at http://www.truecrypt.org/" must be displayed by Your Product (if technically feasible) and contained in its documentation. Alternatively, if This Product or its portion You included in Your Product constitutes only a minor portion of Your Product, phrase "Portions of this product are based in part on TrueCrypt, freely available at http://www.truecrypt.org/" may be displayed instead.'

AFAICS that bit prohibits what I may do with the software and therefore restricts freedom 1. You are not permitted to modify the program as you see fit.

The fact that it appears on this site does not automatically mean it is free software. The admins here are very busy people.

Anybody up to writing good directory software?

Tue, 2007-02-20 11:17 — David Jonathan

Since the very beginning, directories (of any kind) have had a very central role in the internet. (I have recently grown fond of Free Web Directory. Even Slashdot can be considered a directory: a collection of great news and invaluable user-generated comments. As far as software is concerned, doing a quick search on Google about software directories will return the free (as in freedom) software directories like Savannah, SourceForge, Freshmeat and so on, followed by shareware and freeware sites such as FileBuzz, PCWin Download Center and All Freeware (great if you're looking for shareware and freeware, but definitely less comprehensive than their free-as-in-freedom counterparts).

Is better education the key to finding better software?

Sat, 2007-03-03 03:25 — Edward Russel

I read David Jonathon's article Anybody Up To Writing Good Directory Software? the other day, which got me thinking about software directories in general. As David mentioned, many of the software directories one finds when doing a quick google search are free as in beer, not as in freedom. But what interests me is the software directories that already exist, providing a combination of both free as in beer software, and open source software. Sites such as Freeware Downloads and Shareware Download don't advertise themselves as providing free as in liberty software, but each of them have a good selection of open source software available... if you know where to look.
