I've been very quiet on here for a few months, and the reason is (of course) because I've been doing other things. No surprise there, I guess!

What I've been doing, first of all, is writing aCal, an Android CalDAV client with a lot of help from Chris Noldus. It's probably fair to say that Chris did most of the heavy lifting while I learned Java, did most of the UI & graphic design, and the low-level CalDAV synchronisation and geeky calendaring code. This is now available in the Android market for NZD$2.00 to help us fund further development and in a few days (or a couple of weeks) I'll get the source code up somewhere public (probably Gitorious) and it will be licensed GPLv3... When I get a moment - although refer to title :-)

DAViCal 0.9.9.4 is now available, along with AWL 0.46.

This is a recommended upgrade with a focus on stability and reliability.

Release notes are on the wiki at http://wiki.davical.org/w/Release_Notes/0.9.9.4.

Most of the changes are subtle: fixes to small bugs or adjustments to correctness in respect to standards. In particular there were some errors in handling of various requests for addressbook data, and the support for WebDAV synchronisation is updated to draft -04 of the specification.

One notable addition is the new '/feed.php/username/calendar/' URL which will provide an Atom feed of the events added to a calendar. This is pretty experimental at present, but any problems with it won't affect the rest of DAViCal so I felt it safe to include in a stable release series.

I've also created a DAViCal Announce mailing list which in the future will be the primary place that notifications like this are sent to, so those of you who are subscribed here but really only want to see announcements should subscribe to that list.

In a few weeks time (well, when I remember, I guess :-) I want to move the DAViCal General mailing list to a lists.davical.org mailing list. As of today I've moved the DAViCal developers mailing list there already (pretty easy since it did not involve moving servers) but the old address for that one will continue to work indefinitely.

Also, as of yesterday, the sourceforge.net project name for DAViCal finally got changed, so DAViCal is now at http://sourceforge.net/projects/davical - yay!

At the end of January I will be presenting about Calendaring and Free Software at Linux.Conf.AU 2011 in Brisbane - I hope you've all got your tickets already, because there isn't much time left now :-)

For several years I've wanted to join the Calendaring and Scheduling Consortium and go to one of their events to get a chance to meet face-to-face with some of the luminaries in the calendaring world, but every time there is an event it seems to conflict with either linux.conf.au or my brother's wedding or something. Finally I've decided I can make the next meeting, so I've paid over the money to join the organisation and I'm travelling to the US next month for 'CalConnect XVI'. With that on my mind when I saw an HP 110 mini netbook on sale for NZD$588 from Harvey Normans I finally flipped over the 'shall I get one' threshold, hoping it will make a good 'travel laptop' for the upcoming trip.

It's great that in these supposedly straightened times InternetNZ have wasted no time in confirming themselves as key sponsors for LCA in Wellington in 2010.

Now if only all of our other sponsors could line up behind them (please) and tell me the extent of their sponsorship, we would have some facts to moderate our plans...

But seriously: thanks to InternetNZ for stumping up with the basics to make sure this conference will become a reality.

Anyone else looking to sponsor the best linux conference in the world should send me an e-mail.

Soon...

:-)

I was going to reply to this in the mailing list, but after I spent half an hour furiously typing this, I thought it might be better to put it into a blog, for a slightly wider audience, perhaps a more permanent life and partly in an effort to end this thread on a more or less constructive note.

The backchat for this is that the LCA 2009 video has started to go up on the web, and some talks have some gaps in the audio stream... Russell Coker wants to make a constructive suggestion, as follows:

As someone who has not been at all involved with the production of the LCA videos, but who has been intimately involved with the process of streaming DebConf 6, 7 & 8, I think this sort of additional effort will only happen if people voluntarily do it themselves.

Just the task of *watching* all of the produced videos is a huge job for one individual, but as a community of individuals it is quite likely that at least one individual in the community watches each video. If each person who was offended by the quality of post-production work took it upon themselves to fix up only one video then it is probable that we would see some changed. Otherwise I'm afraid it is unlikely.

Most speakers are uncomfortable / unfamiliar with wired microphones. Spares are essential, of course, but the problem can usually be avoided by having a checklist for the audio person to confirm several things:

Before the start of the talk:

• check that batteries are good enough to last for the full length of the coming talk.
• check sound levels are correct for this speaker
• confirm sound is going through to recording
• check the speaker knows how to turn the mic off/on

At the start of the talk:

• confirm sound is going through to recording

At the end of the talk:

• Turn the mic off to save battery.

There are probably a couple of things that I've missed, but if you start with a checklist you pretty soon modify it into a *good* checklist, and it *really* helps when people are under fire.

In fact lapel mics are not the best microphones for these kinds of presentations. The best mics are the ultra lightweight 'headset' models which place a the mic near to the speakers mouth. These do not suffer when the speaker turns their head hard to the left or right, at which points a lapel mic stops getting their speech. They also work well with that more hirsute minority so over-represented in our particular community (alas, that this set no longer includes Bdale :-)

Of course DebConf has a large team of volunteers for streaming the conference, and has developed these kinds of procedures over a number of years. At DebConf there are usually only two main streams, each of which involves:

• The director, operating the video mixer
• Speaker camera operator
• Audience camera operator
• Slides to video convertor
• Sound mixer operator
• Talk timer, to warn speakers at t-10, t-5 & time is up.
• Two roving people responsible for getting audience mics to people talking in the room.

Ideally that really is 7 people (times two streams), and you can get by if you can't find all of the last three, but the other four are increasingly desirable. We mostly manage to do that with volunteers for two streams at DebConf, but for five or more streams at LCA it is inevitably a lot harder, and the quality necessarily has to be cut back to match the resources available.

While it is true that sound is critical to this communication, it is unfortunately also true that most people's (even most geek's) eyes glaze over when presented with a mysterious box with a mere 6 sliding potentiometers, let alone when there are 36 of them, each associated with another 8 rotary knobs, and a rats nest of cables worthy of the worst network nightmare they've seen, and where everything appears to be literally held in place with duct tape.

So it is not so surprising then that while it is relatively easy to find a gadget mad geek capable of operating a camera, or even experienced with operating a camera, finding people with experience operating a sound mixer is an order of magnitude harder.

At LCA the operation appears superficially to often involve a (single) speaker camera operator with a very basic sound mixer which has been configured once by an overworked person who is unobtainable during the actual talk to solve any audio problems. These people are volunteers, and are doing their best, but it simply isn't possible to get a consistently high quality of video and audio in those circumstances.

So as one of the organising committee for LCA 2010 in Wellington I will be watching what we do, and although I don't intend to get personally involved in the video production (I've got plenty of other stuff on *my* plate :-) I do intend to provide what advice and assistance I can. I know that we hope to have some professionals involved (as volunteers), but how many volunteers, and with what levels of skill & experience, we are unlikely to know until much closer than the date. I'll also personally try and get a run-down on all of the audio equipment so that in an emergency, if I happen to be available, I can sub as a sound mixer operator.

So we will try and do better in Wellington in 2010. Come to the conference, though, because we can make no guarantees, and if you do come to Wellington, and you see a single cameraman, and you know something about running a sound mixer, then perhaps you can come and volunteer to help out in that capacity, for the talks you are attending anyway. We'd really appreciate the help.

And finally I must say thanks, in particular, to Holger Levsen for all the learning I have gained since joining the videoteam at DebConf5 in Helsinki in 2005. And too, to all of those past conference teams (LCA, DebConf and otherwise) who have put their best efforts into providing videos of the talks I couldn't see in person. I know it's a bloody hard job, and often a less high profile one, so:

Thank You.

The news is out now, that Wellington will be hosting LCA 2010. As someone on the core team for that (potential sponsors please contact me sooner rather than later :-) I really hope we can do something as awesome as the current week we've had here in Hobart.

Thanks to all of the Hobart team for doing a great job.

For the benefit of Debian users, here's a quick summary of Paul Fenwick's talk about cool stuff in recent Perl versions.

apt-get install libmoose-perl
apt-get install libpar-packer-perl
apt-get install libdevel-nytprof-perl
apt-get install libautodie-perl
apt-get install libperl-critic-perl


Now I have to integrate all that into my writing of Perl programs, which doesn't really happen frequently enough for such changes to become easily ingrained... Great fun, and it's tempting to install Windows just so I could run some of that stuff, but perhaps Paul hasn't realised that you can run Minesweeper under Wine?

Today in Anton Hughes talk at LCA 2009 I saw my photo of Eben Moglen up on the big screen. Woohoo! :-)

As with most of the photos I have put on Wikimedia Commons it is released under PD-Self, so it will be interesting whether he chooses to credit me or not.

He seems to have a pretty good argument, and I hope that this gets visibility and acceptance in the legal community over time. The free software audience is pretty sympathetic, of course.

LCA is once again proving it's premiere status as one of the top free & open source software conferences in the world. Our hosts in Hobart are well-organised and friendly, and though I've been locked into the Systems Administration miniconf by virtue of being one of the organisers, what I've been hearing from the other delegates with the freedom to sample other streams is that all of the miniconfs have once again achieved the high standards that we've come to expect from the conference.

Right now I'm in the keynote by Tom Limoncelli who's giving us all a good kick in the proverbial, to switch us to the mindset of plenty, and to see beyond limited scarcity. Wonderful stuff. Linux == Infinite Love :-)

Tomorrow will be a challenging day, herding the kids through the airports to get to Hobart for a holiday in Tasmania before linux.conf.au 2009 in a couple more weeks.

Sadly I didn't get the DAViCal release out over Christmas that I'd hoped for, and realistically I should face up to the fact that I won't have much chance to push it out until I get back...

Still, it might happen, so don't lose hope! And if you're desperate the current Git head is pretty safe too - so long as you use the head for AWL as well.

I'll only have sporadic net access (until LCA anyway), and my cellphone won't reach me at all, so I guess the world will have to get along without me for a few weeks :-)

Have a Happy New Year - we won't be partying tonight, with a 4:00am start in the morning!

I really have to feel sorry for the people who run Tan-Y-Bryn, self-contained accommodation in Hobart, Tasmania. I booked this place for the second half of January next year because it looked so well-priced for such a great place to stay while we're at LCA as well, as the week we'll just hang around Hobart afterwards.

Unfortunately for both of us, it seems they forgot to note somewhere on some booking site that they were full for that period, and they got a booking through some high-handed booking organisation who said they were liable for AUD$1000 if they refused it. So they cancelled on me, as the easier & cheaper option. A step that wasn't taken lightly, to read the agonised e-mail they wrote me in the small hours of the next morning.

A GPS is one of those toys that I have wanted for a very long time. So last year I finally marshalled enough excuses in one place, lined them up and plunked down some money for a Garmin GPSmap 60CSx in the vague belief that there's enough Linux software out there which understands GPS, and the Garmin is a brand that seems to have mature Linux support. And besides, I'd been told it was a good model that would do what I wanted and then some.

Once I got it I naturally wanted to do stuff with it, and in particular I wanted to connect it up to my laptop which (of course) is running Linux and I found that it wasn't nearly as trivial as I had thought.

This prompted me to run around finding software to use with it, so here's my capsule review of my journey from "extremely naive" to "very naive". Perhaps I'll also learn something from the comments of people who are further down the track.

My first resort was "apt-cache search gps", of course, which immediately brings up such fine sounding programs as "gpsman", described as "A GPS manager" (I haven't managed to get it to do anything yet), "gpstrans" which since it specifically mentions Garmin GPS sounded like just the ticket (it appears to be quite old and superseded). There was some useful stuff as well.

Getting Maps on the GPS

Since the Garmin GPSMap series will display maps, I wanted to be able to get some mapping data on there. There are two map sources I was interested in:

• Map data from NZ Open GPS Maps which gives comprehensive coverage of New Zealand, and is free and community maintained, albeit with some annoying uncertainties about the licensing of the data, and it's being tied to Garmin GPSs.
• Map data from OpenStreetMap.org which gives excellent coverage of many areas of the world, and is free for use under a creative commons license.

Using the NZ Open GPS Maps

The NZ Open GPS Maps are built specifically for the Garmin GPS, so getting them onto my GPS was relatively simple once I found out the exact command line was remarkably hard.

The program that I needed to find to be able to get the maps onto my GPS was sendmap20 which is a free (as in beer) download from the cGPSMapper Website.

I downloaded the maps from the NZ Open GPS Maps hosted on the cGPSMapper site. I needed the files identified as 'binary' files - the installer is a Windows program and no use on Linux. They all have filenames like 64000012.img.

The command-line I first used to install the maps onto the GPS was:

sendmap20 -t/dev/ttyUSB0 640000??.img


That works fine, but if you have even a moderately sized micro SD card in the GPS there are much faster ways. As I found more free maps I found much better ways to do it.

An alternative approach

In the GPS (well, in my one anyway) there is a micro-SD card which is FAT formatted and all of the installed maps are in one humungous combined image of all of the uploaded maps. This means that there is no way to straightforwardly add/remove maps without creating that image, and re-uploading the whole thing. The image file is called 'gmapsupp.img' and is in the 'garmin' subdirectory on the SD card.

This means that you can create the file (or even several different files, with different maps on them) and move them directly on there much quicker, either by taking the SD card out and using it in a USB2 reader (for really big files) or switching the GPS to operate in USB Storage mode (which is USB1, but OK for smaller files).

You can create the IMG file to copy in as gmapsupp.img with sendmap20 also, with a command-line like:

sendmap20 -lNZOpenGPSMaps.img 640000??.img

and then, if you mount the GPS as /media/GPS, you can copy that file on directly

cp NZOpenGPSMaps.img /media/GPS/garmin/gmapsupp.img


QLandKarte

Another program I found useful specifically for dealing with the Garmin GPS Map format is QLandKarte, which understands the native Garmin format and will display the maps in a graphical window.

You can also point and click to select maps, building up a specific set that you can then upload to the device from within QLandKarte itself. This seems to operate a lot faster than sendmap20, presumably because it's driving the USB directly, rather than through usb_serial. To get it to work I seem to have to (a) sudo rmmod garmin_gps and (b) sudo QLandKarte, however, which is definitely not ideal.

For the moment I will continue to use sendmap20 to create files which are sets of the maps I want, and will put them on the device in USB storage mode.

QLandKarte is still very useful, however, for looking at maps and deciding if they are worth bothering with. I used it in this way to select the Australian maps I took with me when I went to Linux.Conf.AU recently. There are more free Garmin GPS maps.

OpenStreetMap.org

Those Australian maps came from OpenStreetMap.org and ultimately I expect that it will become the best source of data for creating maps for my GPS. OpenStreetMap.org is an attempt to provide community-maintained maps for the whole world and which seems to have made significant progress in UK, Europe, America and Australia as well as many other parts of the world.

The data from OpenStreetMap.org does not have the same licensing restrictions as are present even in the NZ Open GPS Maps data (which is relatively free, but has problems similar to the old-style BSD license).

There are also some good mapping interfaces to the OpenStreetMap data although the searching currently still leaves something to be desired. Interfaces are also available for extracting subsets of the data, which is in a fairly straightforward XML format, or you can download the whole lot, but at nearly 3GB for the bzip2 compressed version you won't do it every day.

I gave a brief overview talk about OpenStreetMap.org while I was at Linux.Conf.AU and it seemed to go down quite well (I gave it several times, in fact). You don't need a GPS to contribute to the project, and of course the maps which are being created are usable for many purposes beyond their usefulness on GPS. Some people apparently even print them out, but that just seems weird!

LCA officially started today, with a great opening keynote by Bruce Schneier very nicely pointing out the differences between feeling secure and being secure, and with a few good examples of where these are mismatched and action needs to be taken to fix the mismatch. Good stuff - catch it on video if you get the chance.

Of course for me LCA started on Monday when I got roped into presenting a lightning talk at the Community Wireless miniconf on OpenStreetMap.org which is something I've been fiddling with recently, and a project which definitely deserves more attention. Since nobody else turned up to give their lightning talks my 3 minute presentation was stretched severely out of shape, but the Community Wireless miniconf was generally pretty interesting and I stayed there all day in the end.

Yesterday was the SysAdmin miniconf, and as one of the organisers there was no chance for me to look around at what else was going on. It was a full-on day, and the feedback I have from everyone is that it was a good miniconf. Certainly it was good enough to attract more people than could fit in the 120 seat theatre we initially had allocated so that we had to move into a much larger theatre. A big thank-you to the organisers for so quickly recognising and reshuffling things so that was possible.

All signs so far definitely indicate another great linux.conf.au

Opening the box, we find...

Inside the box was a computer, a power adapter and a battery. There was a bunch of other stuff, but none of that applied to me!

I booted from an Etch pre-release CD I had floating around, most things were detected and most things worked in a basic manner. I don't run Etch though, so I was upgrading to the truly bleeding edge fairly rapidly.

Normally I run Debian Unstable, so I upgraded to that immediately and that was all fine, but with Etch being released soon many developers are putting interesting stuff into Experimental, and I wanted X.org 7.2 and Gnome 2.16 which are in there...

Packages you will want to install

To get the 1400x1050 screen resolution you will need to install '915resolution'. This seems to still be the case with the packages of X.org 7.2. I have seen some interesting sounding options in the i810 man page that might be alternative ways, but the hack that 915resolution uses is a much simpler solution since it is already packaged.

To get the wireless working you will need to install 'ipw3945d' and 'ipw3945-modules-2.6.18-4-686' (or some other package of the modules - I installed the source package and used module-assistant to build the modules because I like to build my own kernel).

What is mostly working

A Tour on the PCI Bus

Display

Once I installed 915resolution the display just works under X.org 7.1 and X.org 7.2. After a suspend to disk I have to run 915resolution again otherwise X will be shown in 1024x768. I think I could then run xrandr to switch back to 1400x1050 at that point (to be confirmed).

Touchpad

The touchpad has a scrolling area at the right of it, which works as designed, and it also seems to handle a two-finger tap as equivalent to a two-button click (i.e. what would normally be a middle button click). It seems nice, and I will probably get used to it.

PCMCIA

I pulled out my 3G card and plugged it in and it just works.

There is also one of these new fandangled PCMCIA^WCardBus replacement whatsits, but I don't anticipate having anything that actually uses that any time soon.

USB

All USB ports seem to work as expected. I seem to get pretty high speed transfers out of my camera too.

SD * MS/Pro * MMC * SM * XD

This was something that I was hopeful would actually work, since I have a few devices that use SD cards now and it definitely seems to be the format that is taking over from Compact Flash, except for in irrelevant stuff like Sony and Olympus equipment.

Unfortunately, though I compiled all of the MMC kernel stuff into my kernel (as well as the core under "Device Drivers -> MMC in the kernel configuration there are chipset drivers under "Device Drivers -> Misc devices" - go figure ). Those drivers seem to be for a "TI PCI74xx compatible" reader, and mine seems to be a "PCIxx12" something, so perhaps there just isn't a driver Right Now and I just have to wait a few months.

Update: 2007-02-23
Using the driver from http://developer.berlios.de/projects/tifmxx this is now working with a 2.6.20 kernel.

What Ain't Tested

Bluetooth

I can see the bluetooth is there with 'lsusb', and I expect that it will all work just fine, but I don't have anything that does bluetooth, so I can't say for sure.

Modem

I don't have a poorband account anywhere, so I can't test it. It isn't something I expect to ever want to use, but it looks like an AC97 modem so I expect it will work just fine.

TV Out

Since I don't have a television.

Parallel Port

Didn't these things get replaced by network printers and USB printers a bunch of years ago?

Serial Port

Yep. It has one. Weird. I wish that they had put two USB ports there instead - it would have been a much better location for stuff like my wireless mouse to plug into.

Firewire

I must pull one of my firewire HDs out and see if this works...

What Ain't Working

Suspend / Resume

Suspend to ram sometimes works for me, but on most occasions resume has left me with a working system but no keyboard input. Some googling suggests there are ways around this, but I am not sure if it is fully reliable at this stage. I have tried with the 'irqpoll' option included on the kernel boot line, which is purported to help with other laptops, but this (a) doesn't help, and (b) lots of other stuff seems to work badly with it.

Somewhere I read a suggestion to use the 'noapic' boot option, but this won't boot. I have a vague memory that the APIC is actually required for SMP systems.

Suspend to disk works, except that X comes back without the BIOS manipulations that have been done by 915resolution, so it manages to end up in a 1024x768 screen rather than 1400x1050. This can probably be fixed by also running 'xrandr' to set the resolution back after '915resolution' has been run, or by 'chvt 1' prior to suspend, then '915resolution' on resume before 'chvt 7' to bring the X screen back. I will see... Update: 2007-02-23 Suspend to disk works reliably for me now that I "chvt 1" ... suspend to disk ... "/etc/init.d/915resolution start; chvt 7".

If the keyboard is not working after a resume from ram I can plug in a USB keyboard and that does work, but unloading and reloading the atkbd, psmouse and libps2 does not help (as I had hoped it would).

This is really important to me, so I'll keep working on it until I can either workaround the problems, or it gets to be supported by 2.6.21 or so... Hopefully sooner rather than later!

Fingerprint Reader

Well, I honestly wasn't expecting to have much luck with the fingerprint reader, and I haven't. A bit of googling did throw up Michael Crusoe's Bio API implementation which I have been unable to get to build so far, as well as the proprietary driver for the UPEK fingerprint reader, which refuses to install, probably because the Bio API isn't installed...

Looking at the output of 'lsusb' it seems that it may well not be a UPEK device, since I am told "Bus 001 Device 004: ID 08ff:2580 AuthenTec, Inc.". More investigation is clearly required.

That is all more than I expected to be there, to be honest, but unfortunately not enough to get me going. Oh well, I will have to take some heart from the fact that these devices are cute, rather than fully trustable.

If I do eventually get it working, I now know that I need to revisit this setting up the fingerprint reader page, which seems comprehensive.

Overall Impressions

Background

My main complaints with my old laptop (a very large Sony Vaio) were it's utter crap battery life (around 50 minutes when new, dropping to 35 or so now), it's poor performance relative to current dual-core CPU systems, and it's weight. I did love the screen on the Vaio, but it's docking station was becoming unreliable and various "Sony-isms" had never worked. My son was throwing some scissors around one morning and managed to spear a chunk out of the screen which also made it less appealing.

So while I was at LCA this year I took the opportunity to ask Keith Packard what laptop he would recommend. He clearly wants one of the new Panasonic Toughbooks, but they are not in my price range. He did also recommend some HP notebooks however and that is what I have gone for in the end though a slightly different model.

... and so?

I have to say that the "out of box experience" is very good. All of the important stuff "just worked" from what was on a four-month old Etch install CD. The hardware is pretty much Intel all down the line, which is the best way to go for a Linux laptop at present. The only proprietary code seems to be some firmware for the wireless, and that doesn't come with complexly encumbered distribution, so it is easily installed.

The only outstanding problems right now are keyboard failure on resume (the laptop actually works because I have managed to cut and paste commands from other bits and pieces on the screen using the mouse!).

While a few pieces of hardware are untested so far (I don't have any bluetooth devices, for example), the two that don't work are really irrelevant luxuries. The bottom line for me is that I now have 2 CPUs, 2G RAM, 100G HD, Wifi, LAN, a reasonably good screen working well with X, a decent battery life (and it also takes an additional battery, which I will get before I next leave the country).

It is a bit of a shame to not have a higher resolution screen, but it seems that Intel don't produce graphics cards beyond 1400x1050 and I'm seriously sick of the endless fiddling that has seemed to be necessary for me to use the ATI and NVidia drivers.

Overall a "B+".

Updated 2007-03-22

It seems that 915resolution is no longer needed with Xorg 7.3 (as I expected, to be honest). Using a small patch to the latest Xorg -video-intel drivers everything works and I am able to nicely expand my desktop across to another monitor when I resume at work, and contract it back when I am only using the laptop panel. Nice. Worth another blog post, so I'll write that in a minute.

Meanwhile, this bug will be fixed before Xorg 7.3 is released, I am sure, and things will work brilliantly after that!

Here at LCA it seems that some people want shared calendars, so I'm pleaased to be able to tell people that I have spent the last 9 months thinking about and writing a CalDAV server.

While it isn't finished yet (is software ever finished?), it does work just fine with all of the free CalDAV clients that are available, and a number of nice people have translated it into six languages so far.

So if you are at LCA and want to know more catch me at tonight's penguin dinner.
