“Nordic” Projects?

4 Comments

It did struck me why the idea of handing the Nordic Free Software Award to a project feels like a bad idea: Free Software projects really aren’t geographical in general.

People tend to live at a fixed location for a specific time and thus you can say that N is living in a Nordic country or not.

Free Software projects however, are not even allowed to exclude people from other places and even projects that may origin at once place or even have its largest user-base in a particular geographical spot.

Last year’s Nordic Free Software Award was handed to Skolelinux since I believe the project origins in Norway (a nordic country) and some of the leading persons in the project are Norwegian. But is that then a nordic project? I don’t want to claim that it isn’t because I honestly don’t know, but their web site certainly says nothing about it being restricted or limited to nordic countries in any significant way. If it does, I couldn’t find it.

I am the primary person and maintainer behind curl but I wouldn’t dream of calling it a “nordic” project. The trio who started Rockbox are all Swedish but calling it a nordic project would just make me laugh.

Isn’t it so, that if you can come up with a “Nordic” Free Software project that currently only lives and strives within one or more Nordic countries without spreading itself over the world, isn’t that then more likely to be a proof of a failure of said project than anything else?

Your favourite Free Software persoject!

So they’ve opened the nomination process for the Nordic Free Software Award 2008.

Now’s the perfect time to run over and submit your favourite “nordic” free software person and have him/her get some of the appreciation he/she deserves.

Ah you can in fact also nominate teams or projects for this award as well, as last year the Skolelinux was awarded the price. I’m actually not really sure that I like that. I think the price should either be for single persons or for teams and projects.

If you rather be in the jury for the awards, the guys are also looking for such people!

Bright Mobile Open Source Future

There have been so many open source initiatives for mobile phones in recent years it’s not even funny (limo, openmoko, Android to name some of the possibly biggest ones). The amount of actual phones on the market using one of them have been very very limited. Apparently there are some Motorola phones running Linux and you can get the Linux-based Nokia N800 tablets but they’re not even phones!

Obviously something has happened in the market though. Perhaps all those initiatives have pushed the big ones into thinking in more open source ways. The most interesting part of today’s news about Nokia buying the entire Symbian is their stated intension to open source it. (they’ve even already chosen the Eclipse Public License for it). It’ll be intereseting to see if there’s any interesting synergies coming up from Nokia’s previous purchase of Trolltech.

Of course, even Symbian has but a small fraction of the entire phone market as they sold 18.5 millions units in Q1 2008. IDC says 291 million phones were sold in the world during Q1 2008, which thus should position Symbian on roughly 6% of the phones that are sold today in the world!

I’m also curious if this will mean that Nokia will use Symbian on a larger scale on their own phones, as currently they seem to use Symbian only on a very small portion of their high-end phones. With Nokia owning the whole thing, they might see a bigger motivation to consolidate their own use of operating systems.

alpine in, pine out

2 Comments

As one of the last living dinosaurs on the planet still using text-based email clients, I realized that pine has been replaced by alpine and I upgraded to that. When doing some reading up on the subject, I noticed that there’s another old grumpy guy still using this client. I’m not sure exactly what that says…

Anyway, the upside of this switch is that this client is now distributed under a proper open source license (Apache license 2.0), as that’s what I’ve been getting in my face from mutt users for years when I’ve explained what I use! (I mean the complaint that pine wasn’t proper open source)

Coverity’s open source bug report

The great guys at scan.coverity.com published their Open Source Report 2008 in which they detail findings about source code they’ve monitored and how quality and bug density etc have changed over time since they started scanning over 250 popular open source projects. curl is one of the projects included.

Some highlights from the report:

  • curl is mentioned as one of the (few) projects that fixed all defects identified by coverity
  • from their start, the average defect frequency has gone down from one defect per 3333 lines of code to one defect per 4000 lines
  • they find no support to backup the old belief that there’s a correlation between function length and bug count
  • the average function length is 66 lines

And the top-5 most frequently detected defects are:

  1. NULL Pointer Dereference 28%
  2. Resource Leak 26%
  3. Unintentional Ignored Expressions 10%
  4. Use Before Test (NULL) 8%
  5. Buffer Overrun (statically allocated) 6%

cURL and libcurl, Licensing

The curl and the PHP

We have a sort of symbiosis between the curl project and the PHP project, at least we in the curl project get a lot of people learning about curl the first time when they hack PHP. This happens to the extent that to a lot of people, curl is but the name of a PHP extension.

So while we can thank the PHP project for referring us a bunch of users that might not otherwise have found us, there is also quite some “friction” or perhaps better called “disagreements” between our projects and how we (don’t) interact.PHP logo

name

CURL vs libcurl vs cURL. We only ever use the funny casing cURL when referring to the cURL project. The cURL project produces curl and libcurl. curl is a command line tool and libcurl is a file transfer library.

The PHP team provides and distributes an extension they call CURL which is a libcurl binding for PHP. This naming causes a great deal of confusion to PHP users who go to the curl site only to find that it isn’t at all devoted to (just) the PHP extension but instead there’s mostly a lot of other curl stuff there!

I’ve discussed this naming issue with the PHP team on several occasions but they don’t agree with me that this causes confusion, and even if it would cause confusion they seem to be of the opinion that it doesn’t matter since the PHP users should find all their info about CURL and related matters on the PHP site and thus it doesn’t matter what the curl site shows or not. (Or something similar to that, I really don’t mean to put words into their mouths so you better ask them about this to get their real and unaltered view – see my link to an old conversation for some info.)

I tend to call it PHP/CURL just to make sure it is clear that we’re talking about the binding. This of course also confuse users since that’s not what it is called in the PHP documentation…

irony

PHP themselves recognize the problem of related projects borrowing the name, so they forbid derivate projects to include “PHP” in their names. Clearly stated in paragraph 4 of their license.

versions

The binary build of PHP for windows have libcurl built in statically with the curl extension code, so people can’t easily replace the libcurl version used by PHP. And in general, Windows people using open source are much less likely to ever build anything on their own in my experience.

PHP 5.2.6 was released on May 1st 2008 still has libcurl 7.16.0 built into the Windows version. That libcurl version was released in October 2006 and right now we have released eight (8) releases after that one. All of them including many bug fixes. This is more than slightly annoying.

support

This isn’t anyone’s fault but… there really aren’t many PHP people who are involved or care about the libcurl binding so those who have PHP/CURL problems tend to ask questions on the curl-and-php mailing list and in the #curl IRC channel but there aren’t any PHP insiders around in those areas to answer PHP questions…

development

Is it just my imagination or isn’t there a lot of PHP users that have asked for the same features in the PHP libcurl binding for a long time by now, but really very few actually step forward and make a difference? So these features remain unfixed and not added. This is even “just” a binding, nothing of the really hard work is done in the binding itself… It might just be me and my head, but the ratio for doers/plain users in the PHP world seems to be exceptionally low in comparison to many other open source areas I see. Of course this is tainted by me only really seing the PHP/CURL side of the PHP world.

future

I have no reason to expect anything to change, nor do I know how I can make anything of this change on my own so I assume things will just continue working exactly like this in the future as well…

Burn Info, burn!

2 Comments

There’s one thing the GNU project has done wrong (and thus the followers of it, like the Debian Linux distribution and others) and it is with their stupid preference to not provide proper man pages but instead insist that the user runs “info [whatever]”. In Debian you also very often have to install a separate doc package to get those info files, and I fail to see the logic in providing tools and libs etc without the proper docs. (and in fact in many cases the info page shows the man page until you get that proper package installed!)

Man pages may not be the best format in the world for docs, but I rather have a proper man page for all commands and then I’ll go html online for extended information. Info is just plain annoying and we should bury it. The sooner the better!

And yes, it is not a coincidence that no project I’m actively driving as a proper contributor are producing any Info documents…

More Means Less

1 Comment

Less is more it is said, and I can certainly subscribe to the reverse: more means less. The two primary open source projects I spend time in have been growing the last years, in source code contributions, but also in amount of users and in amount of contributors. I see the similar effects on myself and on my own role in both Rockbox and curl: I do more and more coordination, planning, admin work, talk (chatting on IRC, responding to mails etc) and “guidance” than actual coding work. My code/non-code work ratio has decreased massively.

This is not complaint, just an observation!

It makes sense to me that early on in a project, and until there’s enough momentum to get the project to more or less drive itself, it is important with a driving core that pushes the project forward. That makes sure every little peace fits together and gets the proper attention to make it a good product and project. As time goes by, more and more people get that knowledge, that ability and the amount of people that drive the project forward increases.

So being an “elderly” in both these projects, I’m more of an advisor, talker, tinker, admin, than a lead programmer now. This is at least most notable in Rockbox, since we have 80 committers now and I think at least 50 of them are active.

I probably spend roughly the same amount of time: somewhere around 2-3 hours/day on my open source projects.

Of course, in my particular case exactly now, I’ve also just recently ramped up my working hours and find myself trying to get accustomed to this life with full-time work, a two-kids-and-wife family and several time-consuming spare time projects. It takes a great deal of juggling and less sleeping.

Nothing is forever so I’m certain my situation will change over time. I’m determined to continue hacking in both projects. And my juggling skills will improve…

playogg without Rockbox?

playogg logoI find it noteworthy that the FSF runs a campaign they call playogg in which they detail the importance and stuff why people should avoid non-free formats and instead use Ogg Vorbis in preference to mp3 for example.

Yet, they document a number of alternatives for Mac users, for Windows users etc on the front page, but there’s not a single word of advice for people with portable music players. Then again, it is very hard for people to find free software alternatives to their portable music players and FSF being so very anti-closed source this makes me wonder why there’s no mention of Rockbox, ipodlinux or even sansalinux to be found?

The only place with this info that I could find when following links from their site, was about three clicks away on xiph.org’s PortablePlayers wiki page but the majority of the stuff mentioned there is non-free…!

TI and Neuros but is it open?

1 Comment

Neuros put out a press release yesterday saying that
“Neuros and Texas Instruments create new bounty program for next-gen Open Internet Television Platform“, and Joe Born of Neuros said on their mailing list that “it will be a complete open platform that will allow developers of all levels to contribute and port applications.”. You can also read some additional thoughts and ideas in the ARS Technica article called “TI and Neuros team up to build open source media platform“. It is basically a hardware platform based on TI’s TMS320DM644x DSP system-on-a-chip line, also called DaVinci. There’s no coincidence of course that the Neuros OSD 2.0 will feature that.

Personally, I’m not convinced when I see TI speak of Open Source since I’m fully aware of their history and I even believe that this brand new “open” platform still requires TI’s restricted-but-free compiler for the DSP. Of course it is more open than many other platforms, but I dislike when someone tries to sound all fine and dandy while at the same time they’re trying to hide some of their better cards behind their back.

A truly open platform would not give TI an advantage. It would offer anyone wanting to do anything with it the same chance. This platform does not. After all, having it built around one of SoC flagships should be enough for them and should be a motivator for them to make this as successful (and thus as open) as possible.

I think it is sad that Neuros repeatedly does this kind of statements. Their original “open source” player was never open source (to any degree). Their OSD player is largely open source but huge chunks of it is not. Now they try to announce even more openness for an entire platform and yet again they fail to actually deliver a truly open product. Neuros shall forever be known as the company who seems to want to do right, but always fails to in the end nonetheless.

Update: Joe replied on the list to my question about the DSP tool(s) and it certainly sounds as if TI may in fact release a more open tool and/or even a gcc port!? If that turns out true it will of course squash most of my complaints here!
