Phew, after a long struggle I’ve managed to upgrade from Debian Sarge to Debian Etch (what will be the next release) on this Xen VM at RimuHosting, so here’s hoping it’s worth it! 🙂
One benefit is that Etch now has a libc6-xen package which should be useful.
Please report any problems you see here, or by email to chris at csamuel.org!
New Scientist has a rather interesting report on how the IPCC may be a little too conservative in their estimates of sea level rise due to climate change.
Previous estimates of how much the world’s sea level will rise as a result of global warming may have seriously underestimated the problem, according to new research.
This is because a new study, by Professor Stefan Rahmstorf, has been published in the journal Science which uses empirical data and computer models rather than relying solely on computational techniques. It apparently matches measured sea level rises very accurately and the New Scientist report goes on to say:
For a given amount of warming, Rahmstorf says, the rise in sea level “could well be twice as much as was so far expected, based on the last IPCC report”.
What does that mean in reality ?
At the top of the range of possible temperature rises estimated by the last IPCC report, the rise could be as great as 140 centimetres by 2100. That would be bad new for cities like London and New York, which lie close to sea level, and would leave them facing an increased risk of devastating storm surges. Even the lowest predicted temperature rises would cause a 50 cm rise, Rahmstorf says.

Here’s a nice bit of installation art of a slightly subversive nature, Mark Jenkins tape sculptures “The Storker Project“.
A variation is his Storker History.
In January 2007 Melbourne used a grand total of just over 35 million litres of water, down 24% from January 2006.
Each day in South Australia BHP uses over 32 million litres, all extracted from the Great Artesian Basin, and doesn’t pay a cent for it. Still, at least they didn’t increase it to the 150+ million litres a day they wanted to..
NB: BHP’s water use does not impinge on Melbourne, so don’t think I’m saying I don’t believe in the water savings that are so necessary here!
It appears that our prime minister believes it would be inappropriate to bring retrospective legislation in to charge David Hicks with offences in an Australian court, but does think it is OK for the USA to do so, even though some prominent US citizens don’t think too highly of ex post facto legislation:
“The sentiment that ex post facto laws are against natural right, is so strong in the United States, that few, if any, of the State constitutions have failed to proscribe them. The federal constitution indeed interdicts them in criminal cases only; but they are equally unjust in civil as in criminal cases, and the omission of a caution which would have been right, does not justify the doing what is wrong. Nor ought it to be presumed that the legislature meant to use a phrase in an unjustifiable sense, if by rules of construction it can be ever strained to what is just.”

The BBC Trust is currently carrying out a consultation exercise into their new “On Demand” TV services over the Internet in which they ask “How important is it that the proposed seven-day catchup service be available to consumers who are not using Microsoft software ?” (see question 5).
The accompanying PDF says:
In respect of the seven-day catch-up over the internet service, the files would require DRM to ensure that they were appropriately restricted in terms of time and geographic consumption. The only system that currently provides this security is Windows Media 10 and above. Further, the only comprehensively deployed operating system that currently supports Windows Media Player 10 and above is the Windows XP operating system. As a result of these DRM requirements the proposed BBC iPlayer download manager element therefore requires Windows Media Player 10 and Windows XP. This means the service would be unavailable to a minority of consumers who either do not use Microsoft or do not have an up-to-date Microsoft operating system. However, over time, technology improvements are likely to enable even more efficient methods of delivery. Further, it is our understanding the BBC Executive are working towards the iPlayer download manager being able to function on other operating systems.
and go on to say:
We also note that the Microsoft-based strategy for rights management will limit usage. Normally, we would expect BBC services to be universally available, as universal access to BBC services is in the public interest. However, as set out above, other mainstream technology platforms do not currently provide the appropriate security.
So the BBC Trust do want greater usage, but don’t seem to understand that DRM will stop that even if people do have access to Windows.
People may want to make their feelings known on this..

There’s been an ongoing discussion on the Beowulf list for Linux clusters about SGI and Windows clusters (which I’ve not had a chance to read), but as part of it the inimitable Robert G. Brown (or one of his AI bots that he must use to keep up his prolific and ever useful posting rate) wrote a lengthy and very interesting piece about why he is, and others should, be afraid of Microsoft’s dominance. It is written in response to a posting from a Microsoft employee, which in itself is an interesting turn up.
He makes lots of references to “hydraulic monopolies”, so it is worth reading up on hydraulic empires for some background to the historical context.
One point he makes is about their impact on pension funds:
Finally, there is Microsoft and pension plans and the general stock market. This is perhaps the scariest part of Microsoft’s supermonopoly status, one that a gentleman named Bill Parrish seems to have devoted himself to uncovering and laying bare to an obviously uncaring world. Microsoft stock is a rather huge component of stock owned by both pension plans and individual “S&P Index” investors (and individuals) all over the world. If Microsoft stock were to collapse, or even to slip steadily down in nominal value, the economic consequences would be catastrophic. It would make the collapse of Enron look tame by comparison, because Microsoft is considerably larger at baseline than Enron ever was. This creates a HUGE disincentive for individuals and companies to challenge Microsoft’s hydraulic legacy — Microsoft has essentially tied the future well being and wealth of an entire generation of corporate employees and index fund investors to their own continued success.
Here he is using an essay by the afforementioned Bill Parish which was done as an editorial for Barrons (from the WSJ people) in 2003 and available online, where Mr Parish writes:
For anyone owning a S&P 500 index fund, Microsoft automatically was almost 4% of their investment. Microsoft’s stock has since declined 58.5%, from $58.38 a share on Dec. 31, 1999,(adjusted for a subsequent split) to $24.21 on March 31. That’s a loss of more than $363 billion, an amount exceeding the gross national product of all but a few nations. The loss also happens to be almost five times the total market value of Enron at its peak.
For reference, MSFT are currently trading at US$30.74 and a market capitalisation of US$302.19 billion. That’s about twice the GDP of Ireland and half the GDP of Australia.

This is a minor bugfix release to the 1.2.6 series of Vacation inspired by looking at the sorts of things Linux distros patch for their own usage.
Vacation no longer builds as -m486 by default, though it will build as 32-bit on AMD64/EM64T because GDBM is not 32/64-bit portable and trying to run a 64-bit version against a 32-bit created GDBM causes it to fail and syslog a success message. This is sub-optimal.
The Makefiles CFLAGS handling has been tidied up a fair bit as a consequence and will hopefully make life a little easier for distributors and it no longer tries to strip the vaclook Perl script on install, which was very silly.
Vacation also now accepts the -i option as well as -I to initialise its database.
Another quick release, this time changing the address parsing for From: and Reply-To: headers to use Eric Raymonds rfc822.c library from his Unix Cookbook and fetchmail rather than the old homebrew code which couldn’t parse many RFC2822 addresses. You can enable the old behaviour by compiling with the -DOLD compiler option (though you probably won’t want to).
It also fixes the bug that broke the -r option, there was a stray “:” in the getopt(3) call that meant it expected an (unnecessary) argument.
There’s a couple of trivial tweaks too.
Please report successful and unsuccessful uses!
