Android least open source mobile platform

Interesting read: Android is least open of open source mobile platforms over on ArsTechnica. Valuable points are made. Also interesting is that the most open platform, Eclipse, is generally believed to be a disaster to work with. It's so flexible and open and customizable that the general public won't be able to get it suited to there needs.

True openness let's anyone contribute anything they feel like. Through a process of community-driven discussion and cherry-picking, various fixes and enhancement then find their place into the product. However, quality control, consistency checks and overall architecture are often overlooked or under staffed and, as a result, don't take place. It's also not a fun job to do, to have to tell people that what they did was great but can't find a place in the product because it breaks "the general idea". Someone sees a thing, investigates and works on it. If you shoot that down all the time, that person will never again help.

Geohot advises against updating PS3 firmware

If you have a PS3 and use the 'Install other OS' feature, the next update - coming this Thursday, will remove that version and apparently any OS installed thru it.
It seems Sony's pushing the firmware update to remove the threat of PS3 hacks, so the hacker warns to update until he's found a way to retain the possibility of installing another OS. See Engadget for details.

Superboot: how to get root on the Acer Liquid A1

Following a brief exchange of notes between MrVanes and myself, I got thinking of getting root on my Liquid. I.e. I can become superuser and do whatever I want to on it, including breaking it beyond repair. :) Life on the edge! ;)
Anyway, not decided yet. Still trying to see if I can get Google Maps Navigation working without root. But just in case, here is howto root the Liquid using a utility called "Superboot".

How Last.fm works

On Slashdot I read a brief about an interview that CNET did with the guys behind last.fm. The interview shows some of the ways that power last.fm, i.e. a 'behind the scenes' of last.fm.

They run Linux (yay!) and use MogileFS, a distributed file system much like a software RAID system for reliability and redundancy. (Which, BTW, Hyves and Marktplaats also use.) They also use SSD drives abundantly, for speed obviously.

Nokia N900 mobile computer


Oh and speaking of Internet, should the Android Liquid A1 fail (available early december), then I can always change over to the fabulous Nokia N900 mobile computer. It runs Maemo5 Linux, has 32 GB of RAM, 1 GHz ARM processor (underclocked to 600 Mhz) and all the connectivity options anyone could want need. The specs are simply mouthwatering! A-GPS, 3D OpenGL support, Bluetooth 2.1, USB 2.0, microSD slot for up to 16 (!) GB.

Update: T3 has pricing info
Update2: T3 also has a review.

Digitally pimping a home network

While visiting Michiel in Singapore, I pimped their home network a bit. It was fine, but cumbersome and loosely tied together: 5 laptops, PS3, Wii. They have a cable modem, but didn't know their connection speed. WiFi was setup but not used because downloading over a fixed connection into the WiFi router was "going faster". Hehe, I told them their ISP limits the speed and after a bit of testing concluded that their 8 Mb down-link would scarcely fill the 54 Mb/s bandwidth of their 802.11g WiFi network. So no need for the fixed network hook-up not sitting near the router, freedom to sit around the house wherever they wanted to. I moved the Linksys WRT54G into a nook, out of the way, receiving thousands of thank-yous from the housekeeper who hated the nasty blue box on the floor in the livingroom. ;)

I then tied the PS3 and Wii to the WiFi network. This meant all devices were now on the same subnet. I installed PS3 media server on Molina's Vista Acer laptop. (It's free, open source and supports Windows, Mac and Linux!) Up until then, they'd had borrowed the HDMI cable from the PS3 if they wanted to watch downloaded TV series. Fine, but why swap cables?! :) Now, they hook up USB disks with movies, music and series to the Vista laptop, fire up ps3 media server, turn on the PS3 and watch or listen to anything from the Windows laptop. :)

linksys WRE54GNext, after seeing this digital revolution in his house, Michiel asked if he could somehow get WiFi on his 17 m2 roof terras, overlooking the Singapore skyline? I said sure, but he'd likely have to drill a cable up to the roof. The reinforced concrete would be unlikely to pass his WiFi signals. So did a little digging and after MrVanes suggested WiFi Range Extenders (I had been looking for that term), it all came quickly together:
* get a WRE54G Linksys Range Expander to get unobstructed full speed WiFi access outside on the roof
* pulling a cable up from the livingroom
* Connect a QNAP TS-410 NAS server to a free network port on the WRT54G and add some disks to taste.

QNAP NAS SOHOThe NAS supports Windows, Apple and Linux, has built-in everything and is expandable with hot-swap drive bays. The UPnP/DLNA media server supports their PS3 so the Windows laptop can be used as a workstation instead of doubling as a media server, the built-in bittorrent (BT) client let's them download directly to the NAS and the iTunes server let's them stream their music collection to their laptops, iPhones or iTouch devices. If only I could be there to install it and see it work!!! :)

ZFS gets inline deduplication

One of the file systems out there, IMHO, is ZFS by Sun for Solaris. Sadly, they can't open source it easily because there are portions that can't be licensed under the GPL license. And if they take them out, there isn't much left of the strength of ZFS. Oh well...

Anyway, ZFS gets inline deduplication! This means, that ZFS can decide -on the fly- if a data block was already written by another process at another time and know where that was. It then merely needs to store a pointer to that particular block elsewhere on the disk (an inode) and it's done.
Expensive data center storage solutions such as NetApp and EMC use this technology too, but these boxes cost $100,000+. ZFS is the file system that you use when you format your disks! Any disks! :)

O2Micro Smartcardbus driver for Linux 2.6

Just because it took a really long time to find it and because previous links in forums didn't seem to work, there is an O2Micro Smartcardbus driver for Linux 2.6 kernels available through the MUSCLE project. Other hits I found used a usr:pwd combination in the URL and that didn't work for me. Hope this helps.

Trying to install opensc and openct to get the built-in smart card reader in the Fu(s)jitsu Lifebook e8110 to work with the VPN solution from work. KPN is starting to promote working from home in order to reduce the housing needs for all its employees. 5 years too late if you ask me, but better late than never! ;) But you'll need to use your company (smart)card, if a reader is available, to identify yourself with a VPN client.

Testing it on Ubuntu 9.04 (LiveCDs RULE!) Get opensc through the Universe repository; you may need to edit your apt sources to activate it. And you need pcsclite, also from MUSCLE.
There is also a tool called o2scr that may work. Untested yet. And O2Micro says it has Linux drivers "real soon now". Also untested.

* get O2micro driver OZSCR*
* get pcsclite
* apt-get install libhal-dev
* extract pcsclite
* ./configure
* make check
* make
* make install
* extract OZSCR
* ./configure-release
* reboot

World of Goo Creators Try Pick-Your-Price Experiment

world of goo
What would people pay for a game that normally sells at $20 if they're given the choice to choose their own price?
That's what World of Goo creators decided to try for the celebration of their one year anniversary. :) Turns out, the average price was $2.03 for 57000 games sold. 12% said they were paying the amount because they already owned the game and wanted to get it for a new platform. World of Goo runs on OSX, Windows and Linux, BTW. The opportunity is extended until October 25th, so hurry while supplies last!

Google Android: Acer Liquid A1


I'm glad I know MrVanes because he and I are so much alike in some ways. I'm also glad he told me NOT to go for an HTC Android phone while in Singapore, because the Hero and Magic sucked! Bad feel, bad form, terrible handling Yuck!
Anyway, he spotted the Acer Liquid A1 planned for Q4 (aka now!) with an est. retail price for €400 and an 800x480px screen powered by a 1 Ghz Snapdargon CPU from the good people at Qualcomm. I can't wait! Acer's netbooks are great and the laptops are better than average, so why can't they do the same for Android phones? :)

Open Source GSM Network At HAR2009


At a hacker convention held in the Netherlands very recently, HAR2009 (@har2009), hackers have demonstrated it is very possible to run an open source GSM network for current mobile phones! See Slashdot for brief details or the HAR2009 GSM wiki for details. At the convention, 391 mobile users were able to talk to each other just like on any other GSM network. So cool!

Nokia 'Rover' N900 tablet phone

Apple iTablet, Nokia N-tablet, smartphone, tabletphone, smarttablet... whatever. I've been drooling over the tablet series of Nokia (n770, n800, n810) for as long as they're been around. The latest Nokia 'Rover' N900 is no exception.

Update: Photos of N900 running Maemo Linux

Amazon releases Kindle source code as open source

Amazon lives up to its promise and released the Kindle source code to the world. Basically a 2.6.22 kernel with E Ink drivers and various hardware support. It seems to have a GPL license, but that is as of yet unconfirmed.

Danger: Mac and Linux Chrome builds available

Google has released pre-release or alpha versions of their redesigned web browser for Mac and Linux. While many things won't work (Flash for instance), but I like the Windows version so much (use it at work, where Windows is the law on the desktop :( ), that I'm gonna give it a try and hopefully help report bugs.

MediaWiki Appliance from Turnkey Linux

At work I run a few wikis and while I could install/config the thing myself, I was using an old Linux version, did not have the time to tweak the OS and needed a wiki badly. I had been using an external wiki but security objected and I needed to move it. So I used the rPath mediawiki. But rPath is a bit custom if not proprietary. It's seldomly updated and perhaps even not maintained anymore.
So I found a new MediaWiki Appliance. This one's from Turnkey Linux, based on Ubuntu (Hardy), updated in the main stream and only 180 MB large. :)

Going to investigate it but it seems to solve all my previous gripes...

ppss - Parallel Processing Shell Script

For work, I was looking for a way to increase parallelism in a shell script that was taking too long. :) Don't ask. :)

Turns out Google Code already has the answer: Parallel Processing Shell Script. Another way is to rewrite my script and use Perl. Perl has a built-in ForkManager. so cool... Must look into Perl really soon now!
