Rockbox on iAudio M3

iAudio M3This player’s been out for quite some time and most certainly won’t be found anywhere to be bought as new. Still, Jens Arnold’s been working hard on this port lately and just minutes ago he mentioned that he got sound working on it – and the build table subsequently has all three kinds of the M3 build added to it.

The M3 is roughly an M5 but without any LCD on the main unit, there’s only that one on the LCD! And of course the M5 was almost an X5 but with a greyscale LCD… So it is another one of them Coldfire 5249 based targets. The LCD on the remote is 128×96 2bit greyscale,

The M3 comes with 20 or 40GB harddisk and there’s an M3L around with a larger capacity battery

How many Rockbox ports are there now? It’s hard to tell as it really depends on what level of maturity and how much functionality you require before you count it as an actual port, but the configure script in our source tree has 38 different ones mentioned. I believe some of them are not more than embryos, but there are also other initial efforts not yet added to this script.

Rockbox on Meizu M6

Meizu M6In the eternal chase for new targets to port Rockbox to, the turn seems to have come to the tiny Meizu M6 player.

This 55 gram thing is slightly smaller than a credit card (width and height at least) and it boasts a 2.4″ LCD, 4GB flash and is powered by a Samsung SA58700 (ARM940T core and a CalmRISC16 DSP thing). It has an FM tuner and built-in mic for recording as well.

There’s of course the standard Rockbox forum thread,and an HW info page in the Rockbox wiki.

Other targets with the exact same SoC include the irivers E10, clix and S10. But none of those have a Rockbox port yet.

curl feature freeze March 20 2008

It is yet again time to pause the add-new-features-craze in order to settle down and fix a few more remaining bugs before we go ship another curl and libcurl release in the beginning of April.

cURL

So at March 20 we hold back and only fix bugs for about 2 weeks until we release curl and libcurl 7.18.1.

The only currently mentioned flaw in TODO-RELEASE to fix before this release is the claimed race condition in win32 gethostbyname_thread but since the reporter doesn’t respond anymore and we can’t repeat the problem it is deemed to just be buried and forgotten.

Other problems currently mentioned on the mailing list is a POST problem with digest and read callbacks and a mysterious bad progress callbacks for uploads, but none of them seem very serious and thus terribly important to get fixed in case they should turn out hard-to-fix.

Yes, I picked the date on purpose as that is the magic date in this project. Especially this year.

Flaky kudo ranks on ohloh

While most people I’ve talked to agree with my that the ohloh.net‘s kudo rankings seem more or less random, I didn’t post about this on their site until today when I found such a blatant example of weirdness that I couldn’t resist. One user with 173 commits in a single project and with only a “mere” level-1 kudo received outranks another user with 6800+ commits in 10+ projects who has received 23 kudos (including 3 from level-10 people)…

If this rakning is not due to a bug in the algo, I would say that the algo is bad since this just doesn’t look right.

Of course the whole idea of “kudo-ranking” people is somewhat of a tricky idea to start with, but now that it’s here I think it is worth to make it as good as possible. And by good in this context, I mean that (average) human beings that compare two people should end up placing them individually in the same order as the algorithm does – taken all things into account.

RHEL is never right

Okay it has been known for a while, but I just recently found out so I figure I should help put the light on a recent hilarious article published in the Red Hat Magazine: It is never correct to abbreviate Red Hat Enterprise Linux as RHEL. (That’s actually not the correct title of the article, but the correct title is so ridiculously long I won’t paste it here since it’d take everyone’s breaths away.)

According to this article, RHEL is “never correct” as an abbreviation for Redhat Enterprise Linux – even though Google finds almost 2 million pages mentioning it, and the top search result it shows links to www.redhat.com/rhel/. Limiting the search to within redhat.com gives more than 52,000 hits.

Some people complicate matters more than others…

Open Source Accessibility

SRF (synskadades riksförbund – the Swedish Association of the Visually Impaired) is a Swedish organization that recently expressed concerns about open source (in Swedish), since as they say “open source in itself is no guarantee for accessibility to disabled persons” (my translation).blind person symbol

The argument came up because Mats Odell, a minister in the Swedish government, expressed a positive attitude towards open source within governments (link in Swedish).

I find it disturbing that these visually impaired guys immediately bounce back and seem to imply and think that open source automatically somehow is less useful, less quality, less fitting or less accessible. But sure, open source is not a guarantee for better accessibility, but then nobody claimed it either and I don’t see how any software can be guaranteed to be better. A very weird statement it was I must say.

One perfect example showing how open source adds accessibility is how Rockbox works. By providing innovative functionality, it makes devices suddenly a whole lot more usable to blind or visually impaired persons. There’s simply no commercial alternatives coming close.

Other fine example on how open source makes software more accessible than any closed-source competitor, is in how translations can be done even to very small languages spoken by economically not so wealthy population groups. Like how closed-source programs fail to deliver software translated to the 11 official languages of South Africa and a lot of other ones.

To round off, the orca project makes openoffice, Firefox, gnome apps and Java-based apps accessible. I’m not saying I know all about being visually impaired and how they use open source, but I do know that open source is accessible to a far extent at some places and at others there’s room left for improvement. But open source gives everyone the ability to join in and make it happen.

Tonium’s Pacemaker has little point

1 Comment

I happened to read an article on idg.se (in Swedish) that talks about the people behind the company Tonium and their portable music device called “Pacemaker“.the pacemaker

The description on the site says: “the world’s first pocket-size DJ-system – a superior portable music player enabling the playing of two tracks simultaneously, equipped with an extensive range of professional audio manipulation features allowing for creative mixing between two independent channels. Any mix created can be saved for legal sharing. ”

Having been involved and hacked on portable music players for a few years by now, I can’t but to wonder exactly who this is targeted for and what they are supposed to do with it? I do like the pictures on their site showing business-style persons using it, but why on earth would any ordinary human want to mix songs while on the go?

The IDG article says (translation by me) that (talking about Jonas Norberg the CEO) “it was in January 2005 when he realized that the computing power required to playback video should suffice to play back two simultaneous audio streams“. Yeah – and that was all we had to know in order to quickly see that this guy certainly is not an engineer… 🙂

Of course, there’s also this possibility than I’m just an old grumpy whiner.

Rockbox on Olympus m:robe 100!

Olympus M:Robe 100For some reason I haven’t previously properly pushed this fact here:

The Rockbox port for the Olympus M:Robe 100 is soon about to enter the fine room of all the other existing Rockbox ports. It seems most stuff is working in this port now, and with bootloader and daily zips on the download mirrors there’s only a few minor things left before it’ll go in among the other zips on the build page!

The mrobe100 is a mi4-using PortalPlayer-based (PP5020) target with a monochrome LCD. Here’s the proper forum thread.

Most of the magic stuff done on this port seems to have been pulled off by Mark Arigo with Robert Kukla doing a fair share as well. Thanks guys!
