1. Real Networks has funded a program at the Oregon State University's Open |
|||
(version Q2B21) and with the exception of some final test, has the |
|||
Source Lab to be used for development of open-source multimedia capture, |
|||
completed the candidate build for the software image for B2 machines |
|||
editing, encoding and playback software integrated with the OLPC platform. |
|||
(Build 239). This is the software that will be used in testing with |
|||
children in the coming month in the launch countries. |
|||
2. Sydney: Chris Blizzard, Dave Woodhouse, and Jim Gettys attended |
|||
2. Michail Bletsas reports that the XO was a major attraction in both the |
|||
linux.conf.au. It is a volunteer-run conference located in a |
|||
AMD and Marvell booths at the Consumer Electronics Show (CES). At the show |
|||
different city in Australia or New Zeland and organized by different |
|||
Marvell officially released its wireless firmware with full mesh |
|||
people every year; it is considered one of the best conferences in the |
|||
functionality. Many improvements will follow, however OLPC's mesh is the |
|||
world in support of free and open source software. There were about |
|||
first implementation of the emerging 802.11s standard. |
|||
800 international attendees and another 400 locals who came for the |
|||
"open day." Chris gave one of the keynotes at the conference: he |
|||
talked about Firefox, OLPC, and the relevance of free software outside |
|||
of the context of the server room. He gave a separate talk on the OLPC |
|||
user interface. Jim gave a talk on the process of building the OLPC |
|||
hardware. |
|||
3. Thomas Vander Stichele from Fluendo gave a demo of streaming video |

|||
Build 231 is the new stable release. The firmware version for B2 is going |
|||
to be Q2B20, barring surprises. That version supports the new CAFE and |
|||
DCON chips, and has been tested with network booting for manufacturing |
|||
diagnostics. Please refer to |

reimaging the machine. |
|||
4. Kernel: The wireless driver has gone through two rounds of reviews |
|||
4. UI: This week we saw a lot of activity on the UI and in the builds. Some |
|||
with the upstream kernel networking folks and work continues to get it |
|||
of the more relevant UI fixes from this week include: (1) the Power Button |
|||
into the Linux mainline kernel. Marcelo Tosatti also reports that we |

is now the way to shut the machine now—no more confusing power icon in the |
|||
are down to 5–6 interrupts per second (minus a really bad i8042 |
|||
frame; (2) mousing over launch icons in the frame now gives visual feedback |
|||
driver). This is compared with a ~200 per second in a standard Linux |
|||
that they are buttons; (3) some activity startup blocking problems have |
|||
desktop. This will have a huge positive effect on our battery life. |
|||
been fixed that make activity startup feel faster; and (4) some startup |
|||
feedback for activities—when you click on an icon, something happens |
|||
instead of a long pause that was causing people to repeatedly click, |
|||
launching multiple instances of an activity. |
|||
5. UI: Marco Presenti Gritti made numerous small changes to the UI to |

also spent time pulling together some multimedia extension (MMX) |
|||
libraries and are seeing some speedups as a result—graphics are faster (up |

optimizations for our platform that should help with Cairo and X |
|||
to 30% in some cases) and incur less CPU overhead. |

|||
6. Firmware: Mitch Bradley reports that the firmware for the B2 build |
|||
6. X Window System: Adam Jackson and Jordan Crouse pushed out a few fixes |
|||
is released and seems to be stable. Several new firmware features are |
|||
for the X server. These include fixes in Xv (video support) RANDR |
|||
working, to be deployed after the B2 build: SD driver for booting from |
|||
(rotation support) and a couple of minor crash fixes. We will be |

to work; a graphical touchpad diagnostic that illustrates the detailed |
|||
behavior of the "jumping cursor" issue; and Open Firmware can now do |
|||
the wireless-chip firmware uploading/rewriting process (thanks to |
|||
Lilian Walter). |
|||
7. Community: As we go into B2, we would like to take this opportunity |
|||
6. Power budget: Richard Smith started to look at the power budget and |
|||
to acknowledge the much larger community of people and projects, that |
|||
began to work out a plan for setting up a tinderbox that will be able to |
|||
have made it possible. It is easy to lose sight of them in the |
|||
measure all of the power rails on the new B2 boards in order to have an |
|||
day-to-day engineering we do. |
|||
automated test for power regressions. Lilian Walter worked on the exact |
|||
sequences required for controlling power on SD, camera, and several other |
|||
peripherals, and measured their power consumption. |
|||
Firmware: Ron Minnich (LANL) and the LinuxBIOS team, Sun Microsystems |
|||
7. Power management: Jordon Crouse using got the machine to successfully |
|||
for freeing up Open FirmWare, Richard Smith (OLPC), Mitch Bradley |
|||
suspend and turn off the VCORE_CPU rail. He also got it to wake up by |
|||
(OLPC). Tom Sylla has been invaluable with his in-depth knowledge of |
|||
pressing the power button, which is more impressive then it sounds because |
|||
the AMD Geode. |
|||
it means that the embedded controller (EC) is not getting confused by the |
|||
power state either. |
|||
Audio drivers: Jaya Kumar has, behind the scenes done a superb job |
|||
8. Erik Blankinship and Bakhtiar Mikhak of MediaMods have nearly completed |
|||
with the AD1888 driver and 5536 ALSA support, and has added support |
|||
the main camera activity for the OLPC system. It is being integrated into |
|||
for analog input to the driver and the controls to support them, which |
|||
the B2 software build. Dan and John have been assisting. In developing the |
|||
is dear to the heart of Seymour Papert. He did so in such a quiet, |
|||
application Erik has uncovered a color-map problem that probably resides in |
|||
timely way that it has been easy to overlook his contributions. The |
|||
gstreamer. Jordan is adding RGB-source support to the X Video extension, |
|||
Alsa project in Linux provides the driver framework we use. |
|||
which may make the camera activity “happier”, but the gstreamer problem |
|||
needs to be fixed. |
|||
Camera driver: Jon Corbet, well known in the open source community as |
|||
9. Keyboard LED: Andres completed the keyboard LED driver; after additional |
|||
the editor of LWN, wrote the camera driver under contract to OLPC: but |
|||
cleanups, Andres merged the driver into our kernels. We have working |
|||
the frame work into which it fits is the Video-4-Linux project. |
|||
keyboard LEDs in the latest builds. |
|||
LED driver: Reynaldo Verdejo wrote our keyboard LED driver (which he |
|||
10. Analog in: Andres has started testing the analog-input patches. |
|||
wrote without having access to a laptop!). |
|||
SD driver: Pierre Ossman is the maintainer of the Linux SD driver and |
|||
11. Sugar Activities: Thanks to everyone in the community who has been |
|||
is an invaluable aide in ensuring proper correct support of SD for |
|||
contributing to the B2 build: new versions of TamTam, AbiWord, Etoys, |
|||
OLPC. Richard Smith (OLPC) has been debugging the driver and hardware. |
|||
PenguinTV, are in B2 Test, along with a new camera activity. |
|||
NAND Flash driver: Dave Woodhouse of Red Hat's OLPC team implemented |
|||
12. James Cameron has continued rural (outback Australia) wireless testing |
|||
our NAND Flash driver and is the original author of the JFFS2 file |
|||
with impressive results. As expected, the Laptop's antenna design makes a |
|||
system, but we'd also like to thank the many people who have |
|||
significant difference in range (> 50%); Cameron has had two laptops |
|||
contributed to that project over its life. |
|||
streaming audio in ad-hoc mode over a distance of 1.3km (See |
|||
http://mailman.laptop.org/pipermail/devel/2007-January/003616.html). |
|||
Power management: Matthew Garret, a PHD student in BioInformatics at |
|||
13. Journal: Ivan Krstić spent the week chasing out bugs in journal |
|||
Cambridge University has been helping with power management, posting |
|||
compression and sparse storage and dealing with performance issues. One |
|||
an initial patch for suspend/resume for OLPC and much advice. He is |
|||
challenge is that we want to store semi-structured information, but there |
|||
one of Linux's experts at suspend/resume. |
|||
is no fast semi-structured database, let alone a free one. And while you |
|||
can generally wing it on fast servers by implementing a semi-structured |
|||
Linux kernel: Our kernel, of course, is maintained by a community of |
|||
store backed by a standard relational database, the performance would kill |
|||
over a thousand people from all over the world, too innumerable to |
|||
us on the laptops. Ivan's approach is to use a probabilistic filter that |
|||
name; our immediate thanks to Andy Tannenbaum, who with Minix inspired |
|||
continuously looks at what metadata the user is commonly using for all |
|||
Linus Torvalds to start Linux. The response of this community to OLPC |
|||
files on the system. A nice thing about this approach is that it is |
|||
is overwhelming and our thanks to everyone who in their own way has |
|||
self-maintaining; the potential down side is that it could sometimes |
|||
done their bit to help us. Dave Jones (Red Hat) is doing great work |
|||
misfire, so we have to be careful about choosing coefficients. The really |
|||
finding performance problems in Linux applications and raising |
|||
nice thing about this is that it enables us to do a resource description |
|||
community awareness. |
|||
framework (RDF) export of much of the journal. |
|||
X Window System: The X.org community maintains the window system on |
|||
OLPC. The template for rotation support in our driver that Jordan |
|||
Crouse implemented for this release comes from work of Eric Anholt and |
|||
Keith Packard of Intel, whom we would like to thank for the great work |
|||
that they are doing to improve the base driver infrastructure. Daniel |
|||
Stone of Nokia has been working on the new input system for X |
|||
(Zephaniah Hull has contributed to this work.) Open Hand's Matchbox |
|||
window manager has been the platform upon which we have been |
|||
developing our UI. |
|||
Cairo graphics: The Cairo Graphics library community started by Carl |
|||
Worth and Keith Packard has been rapidly improving its performance, |
|||
which forms the basis of the increasingly high quality of graphics on |
|||
our system. |
|||
GTK+ and Pango libraries: These form the GUI toolkit and |
|||
internationalization foundation, Behdad Esfahbod (Red Hat) has helped |
|||
greatly in our internationalization support as well as performance of |
|||
Pango and Cairo. |
|||
Python: The Python community lead by Guido Van Rossum provides the |
|||
language we use in Sugar, our user interface. They have already |
|||
started performance work that should appear immediately in our builds |
|||
after the B2 build. |
|||
Sugar: Red Hat's Marco Presenti Gritti has been the lead designer and |
|||
implementor of Sugar, our UI. Pentagram's Lisa Strausfeld, Christian |
|||
Marc Schmidt, and Takaaki Okada and OLPC's Eben Eliason and Walter |
|||
Bender have worked on the user interface and graphics design, the |
|||
"look and feel" of our system. |
|||
Camera: A new camera application written by Erik Blankinship and |
|||
Bakhtiar Mikhak of Media Mods replaces our quick and dirty video demo |
|||
on the B1 build. Eben Eliason, Dan Williams, and John Palmieri all |
|||
contributed to this effort. |
|||
Abiword: A new version of Abiword is in this release, which should be |
|||
able to handle complex writing scripts much better; this will also |
|||
form the input applet for our journal application, when it is ready. |
|||
xBook: Manusheel Gupta, Tomeu Vizoso, and Marco Gritti tuned up the |
|||
PDF viewer for the new build. |
|||
Etoys: The Squeak Etoys development is now so well integrated with |
|||
OLPC release engineering that it "just happens"; there are numerous |
|||
improvements, too many to note here. |
|||
Web Browser: Our web browser is based on the Gecko rendering engine of |
|||
the Firefox project. Our display, being significantly higher |
|||
resolution than conventional displays is presenting difficulties; but |
|||
the the Firefox community is hard at work on a new version which will |
|||
improve this situation at some point in the future. A new reflow |
|||
engine should also greatly improve performance in a future version of |
|||
our system. |
|||
Bug reporting: Often overlooked is the work that people do to record |
|||
bugs so that we can fix them. More and more are from users of our |
|||
systems, rather than those directly developing the software. |
|||
Network testing: James Cameron has been an immense aid at early |
|||
testing of the OLPC system in radio quiet areas (he lives in the |
|||
Australian outback). Two of our machines have been able to talk to |
|||
each other over 1.3km apart. |
|||
Infrastructure: It is easy to overlook the importance of |
|||
infrastructure work that people do. Reynaldo Verdejo's work is |
|||
essential to the tinderbox we use for performance. The Mozilla |
|||
organization originally developed the first tinderboxes for automated |
|||
build and performance regression testing. |
|||
Performance: Other often unsung heroes include those who work on |
|||
performance, only some of which has started to land in our builds. |
|||
Johan Dahlin wrote (http://blogs.gnome.org/view/johan/2007/01/18/0) a |
|||
Python-launcher prototype this week that cuts a full second of "import |
|||
GTK." This translates into at least one second off every activity |
|||
startup. Chris Ball also worked with Tomeu Vizoso, Adam Jackson (Red |
|||
Hat), and Dan Williams (Red Hat) on the activity launch notification |
|||
speedup. They have done numerous sysprof traces and benchmarking, and |
|||
found the right combination of MMX functions to use; our X performance |
|||
is much higher now as a result. |
|||
Release Engineering: At the inevitable danger of overlooking someone |
|||
(our apologies), we would like to to thank those directly contributing |
|||
to the release engineering of this software, including Chris Ball, |

Walter Bender, Chris Blizzard (Red Hat), Mitch Bradley, Javier Cardona |
