The Musings of Chris Samuel

It’s not making the news at the moment, but the proposed scrapping of the Medicare rebate for access to social workers and occupational therapists is going to cause a lot of pain to a lot of people. We have friends with Autism and Aspergers Syndrome who benefit from the support these people provide, support that helps these people get into jobs, to live independently or to understand how the world is working. As my own wife puts it:

As a person with autism, learning disabilities and mental health issues from a background of abuse and homelessness, a lot of my skills took years to acquire. I had had a lifetime of labels, Psych and Guidance, medicated by age 9, psychiatry since my teens. But it was a social worker who liased with my psychiatrist to get me – relatively illiterate, innumerate, itinerant and at risk – back into education. The psychiatrist took the credit but it was there I understood the very different jobs these people had in the area of mental health. The psychiatrist could medicate me, but the Social Worker had a more powerful medicine – practical plans and support to change, to save, a life.

When her first husband left after isolating her:

I had spent two years without practicing my self help skills. Agoraphobic, isolated, disoriented, I didn’t need a psychiatrist or medication. I needed practical hands on help in the home and the community to pattern me back into my life skills. That help came in the form of an Occupational Therapist. She helped me get back my strategies and the life skills these supported, helped me get my confidence back and helped me put supports in place for the things I needed help with. Within three months I was running my life as an independent adult, able to commute from home out into the community, even joining in community activities and looking after a cat.

Mental health often flies under the radar of journalists, but it is a significant health issue in Australia. Professor John Mendoza says:

Today, mental ill-health is the leading cause of death for all Australians under 45. More than car accidents. More than binge drinking. More than anything else. It is the leading cause of disability in Australia across all demographics. It affects more than 4 million Australians every year and is estimated to cost the Australian economy about $30 billion each year.

This decision isn’t yet set in stone, it is apparently due to be reviewed later this year but don’t wait for the election, please write and tell the current Health Minister why it is important to keep these services eligible for the Medicare rebate.

Thank you.

The Melbourne Free Software Interest Group (a group of Melbourne computer folks with an interest in software freedom) have put together an open letter to Senator the Hon Kim Carr, the Minister for Innovation, to request that software be excluded from patenting as part of the Australian governments review of patents in general.

We are currently collecting signatures to the letter and if you are in Australia and of a like mind we would really appreciate it if you would contribute your signature too! Just click on the link, read the letter and the form to sign it is at the bottom of the page. Please also pass this on to others you know who may be interested.

Watched the first episode of Nick Crane’s Britannia, about England and Wales, and was interested to see a section about Snowdonia which implied that William Camden, the Elizabethan author of the original Britannia, had said that there were was a lake there which had a floating island in it. It implied that Camden would have come across this story by talking to cattle farmers of the area on his travels through North Wales. But that doesn’t seem to be the case at all, in fact the English translation of Camden’s own text says:

Neverthelesse, so ranke are they with grasse that it is a very comon speech among the Welsh, that the mountaines Eriry will yeeld sufficient pasture for all the cattaile in Wales, if they were put upon them together. Concerning the two Meare [lakes] on the toppe of these, in the one of which floteth a wandering Island, and in the other is found great store of fishes, but having all of them but one eye apeece, I will say nothing lest I might seeme to foster fables, although some, confident upon the authority of Giraldus, have beleeved it for a verity.

In other words he was just quoting Giraldus Cambrensis who, in his “The Description of Wales” (1194 CE), wrote:

the latter of which are said to be of so great an extent, that if all the herds in Wales were collected together, they would supply them with pasture for a considerable time. Upon them are two lakes, one of which has a floating island; and the other contains fish having only one eye, as we have related in our Itinerary.

Even then Giraldus is just summarising what he wrote in his “The Itinerary of Archbishop Baldwin through Wales” (1188 CE), where he says:

On the highest parts of these mountains are two lakes worthy of admiration. The one has a floating island in it, which is often driven from one side to the other by the force of the winds; and the shepherds behold with astonishment their cattle, whilst feeding, carried to the distant parts of the lake. A part of the bank naturally bound together by the roots of willows and other shrubs may have been broken off, and increased by the alluvion of the earth from the shore; and being continually agitated by the winds, which in so elevated a situation blow with great violence, it cannot reunite itself firmly with the banks. The other lake is noted for a wonderful and singular miracle. It contains three sorts of fish – eels, trout, and perch, all of which have only one eye, the left being wanting; but if the curious reader should demand of me the explanation of so extraordinary a circumstance, I cannot presume to satisfy him.

So sadly it appears that William Camden was just referring back to a text that was almost 400 years old when the first edition of Britannia was published in 1586.

The most excellent Joe Landman has a blog post looking at the performance of an anonymous SSD with a Sandforce SF-1200 controller chipset on it, and comes up with some very interesting benchmark results. But first he comes up with a nice way of quantifying the distance between benchmark results and real life:

I need to understand how close the marketing numbers are to the actual numbers. We need to establish a ratio for this. Call this the Benchmark Significance Ratio, or BS Ratio for short. Define BS Ratio as:

BS Ratio = (what they claim) / (what you measure)

A BS Ratio close to 1 is good. A BS Ratio much greater than 1 is bad. Of course, a BS Ratio much less than 1 is either an indicator of a failed test, or an accidentally released product.

What Joe finds is that the performance of the SSD, in terms of basic things like read/write speed, depends on what you write to it. If you write lots of zeros you find the performance is almost 4 times as much as if you write random data to it. Now as Joe rightly points out, this smacks of compression somewhere in the path between the program and the disk which means that most of the benchmarks you see/do (unless they/you, as Joe does, take care to use random data) will be pretty much meaningless unless you plan to just store zeros. Mind you if you do plan to just store zeros then I suggest just using /dev/null for writing to and /dev/zero to read from – they will give you much better speed and far better capacity for free!

What intrigues me though is not so much the speed difference but what that means for the capacity of the device – does it claim to be a X GB device but actually store Y GB (where Y > X dependent on compressibility of data) or does it enforce the amount that it can store to the quoted capacity ? Even worse, does the stated X GB capacity depend on your data being compressible and more random data results in less space ? I think the last can be ruled out because I can’t see a way how you would fake that failure to the SATA layers unless you returned failed writes which could cause chaos, especially in a RAID environment. I also suspect that it must enforce a fixed limit as I presume they must fake some characteristics of a spinning disk (heads, etc) for compatibility.

Which is a real shame because you’ve actually got a storage device that could (given the right sort of data) store far more than its stated capacity, if only you could address it in a non-spinning disk like manner. This echo’s other issues with SSD FTL’s like bad wear levelling implementations, etc, which would go away if we had an open interface into the device exposing the internals, that way you could (with this controller) get extra storage for free and potentially even a better wear levelling system into the bargain.

I guess even if that were available I don’t know if filesystems could cope with that (yet), but I wouldn’t mind betting they’d be up for it!

I recently got a Kobo eReader from Borders Australia and am enjoying it, it’s light and small enough to fit in the inside pocket of one of my jackets and the screen is great. From a Linux point of view using it with Calibre works nicely (at least after upgrading to a more recent version than shipped with Kubuntu 10.04), I’ve even got a hack to get the LWN weekly edition onto it, pending a proper RSS feed of weekly editions from LWN themselves.

However, there has been one fly in the ointment that I’ve noticed, it currently is not possible to override the font size settings generated by Calibre (or other eBook sources) and sometimes that could be really handy. Fortunately a new firmware has just been released (1.4) which fixes that (amongst other things). The supported methods of upgrading are either (a) using the Borders application under Windows or MacOSX or (b) an SD card upgrade – in Canada only.

So how to upgrade your firmware under Linux ? Well the short answer is that (as far as I can tell) you can’t. I tried asking Kobo themselves if it was possible to get a copy of the SD card image and got a quick response saying:

At this time we don’t support Linx(sic) with the Kobo eReader.

I’ve followed that up pointing out I don’t want support, I just want the image file. I’ve also posted on the Borders Australia announcement of the firmware asking for the SD card image too, we’ll see if that gets a response next week. But being a hacker at heart I wanted to see if I could figure out how far I could get on my own.

First stop was this interesting post on MobileRead called “Behind the Scenes – The Kobo eReader Firmware Upgrade” which goes into some detail about the process (an entertaining read too – for instance there’s a section where they say they warn Adobe Digital Editions users that the upgrade will remove the DRM permissions they’ve got, saying “If you are a Calibre user, insert smirk here”). It says:

The wizard downloads the firmware update from our servers. It puts a zip file in your temporary folder. The .zip contains three files that we’re going to update your device with

Great – so if we can get that file then we’ve got the essentials of the upgrade (if not the support tools). Now whilst I don’t have Windows here I do have the Codeweavers Crossover Professional WINE version (a commercially supported WINE from people who contribute back to the WINE project) and so I grabbed the installation executable from the Borders Australia site and ran it under WINE – worked a treat, I could install it, run it and login to the Borders website with it. Downside is that (of course) software under Wine can’t directly access USB devices, so on a hunch I mounted the Kobo eReader under Linux and created a symlink to it called drive_d (to match the drive_c that Crossover Office created). Bingo – it recognised it and even told me there was an upgrade available!

So I followed the bouncing ball, er, instructions and soon saw it downloading the firmware update which it copied into (what it thought was) \windows\temp as kobo-upgrade-1.4.zip. Copying elsewhere and unzip’ing it revealed the aforesaid three files:

-rw------- 1 chris chris 51330048 2010-06-28 12:02 fs.img
-rwxr-xr-x 1 chris chris   167304 2010-06-28 11:49 u-boot.bin-eb600em
-rwxr-xr-x 1 chris chris  1549184 2010-06-28 11:49 uImage-eb600em

Now from my experience with my OpenMOKO phone I can immediately see that it’s got a boot loader (u-boot.bin-eb600em), a Linux kernel (uImage-eb600em, strings reveals it to be Linux-2.6.18.2-ntx600-v0.82) and a root filesystem (fs.img which file identifies as a VMS Alpha executable, but I don’t believe it).

Now I wasn’t brave enough to try and upgrade the Kobo under Wine – and as it turns out it doesn’t look to be possible because when you put the device into its upgrade mode (helpfully described in the documentation as the “Two-Finger + Table Edge Salute”) it stops appearing as a USB storage gadget but instead appears (according to lsusb) as:

Bus 002 Device 011: ID 5345:1234 Owon PDS6062T Oscilloscope

Er, not quite what I was expecting (and updating the USB ID’s with “update-usbids” didn’t change anything). It also makes the kernel whinge:

[876105.561189] usb 2-5: config 1 interface 0 altsetting 0 bulk endpoint 0x81 has invalid maxpacket 64
[876105.561194] usb 2-5: config 1 interface 0 altsetting 0 bulk endpoint 0x3 has invalid maxpacket 64

I was wondering, given the resemblance between the files in the Kobo zip file and those used by the OpenMOKO Neo phone that I could probe for the Kobo with the dfu-util used for flashing the phone, but sadly no joy..

# dfu-util -d 5345:1234 -l
dfu-util - (C) 2007-2008 by OpenMoko Inc.
This program is Free Software and has ABSOLUTELY NO WARRANTY

#

With that not working I thought I’d try putting the 3 files onto an SD card (I had a 512MB one spare) formatted as FAT16 and see what would happen then. First of all I tried it with it as a single partition but it didn’t take any notice of that, so then I tried it as a single device (you need the -I flag to mkdosfs) but no joy with that either (though at least when running normally in that mode it did spot the card being inserted and removed).

Once the Kobo is in its upgrade mode the only way to get it out is to poke it in the back with a paperclip, er, upgrade tool.. That forces a reset.

So that’s about it for me, I’ve exhausted all the means I can think of, looks like until Kobo do release an SD upgrade image we’re all pretty much stuck.

Update #1 Found that there is a beta release of the Kobo Desktop client for Linux out, the URL and some instructions are on the MobileRead forum. DO NOT CONTACT KOBO TECH SUPPORT ABOUT THIS SOFTWARE. It appears to believe it has the ability to update the firmware.

Update #2 If you want to grab the firmware itself the URL it requests is http://download.kobobooks.com/desktop/ereaderupgrade1_4/kobo-upgrade-1.4.zip

Update #3 I didn’t dare strace the application when it was doing the upgrade, but lsof shows it has opened /dev/bus/usb/002/021, which matches it in lsusb (or at least the Owon PDS6062T Oscilloscope it masquerades as).

Update #4 The update worked, completely painless!

Interesting take on why China may well dominate technology in the near future at BusinessWeek:

In China, eight of the nine members of the Standing Committee of the Political Bureau, including the Chinese president, Hu Jintao, have engineering degrees; one has a degree in geology.

Contrast that with the US:

Of the 15 U.S. cabinet members, six have law degrees. Only one cabinet member has a hard-science degree — Secretary of Energy Steven Chu, who won the Nobel Prize in physics in 1997, has a doctorate in physics. President Barack Obama and Vice President Joe Biden have law degrees.

Basically it comes down to political will and understanding on the part of the people with the power.

(Via the ever excellent InsideHPC)

Two interesting statistics from the NOAA National Climate Data Center:

June 2010 was the fourth consecutive warmest month on record (March, April, and May 2010 were also the warmest on record). This was the 304th consecutive month with a global temperature above the 20th century average. The last month with below-average temperature was February 1985.

and:

It was the warmest January–June on record for the global land and ocean temperature. The worldwide land on average had its second warmest January–June, behind 2007. The worldwide averaged ocean temperature was the second warmest January–June, behind 1998.

Yes, those figures are for the whole planet.
