The department move today was very, very long and hard
and tedious, but in the end went very well and I think Monday morning
should be fairly smooth. I think they're going to be extremely demanding
and unforgiving users, actually, and their previous sysadmin has gone up
in my estimation, slightly, just for putting up with them for so long...
I'd forgotten what it was like supporting proper engineers, though - every
PC was strange and peculiar, and every one presented some unique challenge
or oddity to debug. Oh, but I managed to break through the security of an
NT4 workstation that should have had its password removed but hadn't - the
old faithful NT
Password Changer, recently renamed and polished up, helped me crack
the SAM and reset the administrator password (to "bozo") in around four
minutes, which certainly raised an eyebrow or two amongst those assembled.
<buffs fingernails on lapel> It was the high point of the
day... |

It's been another bad-silicon day, today... I needed to
add some new disks to the
LSI RAID
array on the main fileserver, running the new Server 2003 OS, to
accommodate the mass of data I'm acquiring in the departmental move this
weekend. The new drives bound into the existing array nicely enough, but
when I came to expand the volume onto the extra space I found that the
menu option wasn't actually there!
Much poking around at the manufacturer's site finally
suggested that the expansion facility is only
permitted on dynamic disks under Windows 2000 and later, and having
confirmed with our supplier that this was indeed the case I gritted my
teeth and prepared to upgrade the partition. This was a source of some
consternation, as even after three years
dynamic disks are still very poorly supported by
third-party
utilities, and because the conversion is effectively a one-way process
it could well cause problems in future...
In the event, however, I needn't have worried - all
attempts to upgrade the partition returned a "not enough space available"
message, even having moved some files to a secondary server and
defragmented the volume to ensure contiguous free space...
Further research showed that the upgrade actually requires around 1Mb
of unpartitioned space immediately after the partition end, and
under most circumstances this is automatically reserved (ah, so that's
what
that is!) when a partition is created under Windows 2000 or later -
unfortunately the server in question was upgraded from NT4 and the
partition fills the RAID volume. Even if it hadn't been, though, there
would still have been
issues if the volume was created as a basic disk and later upgraded,
as is the common practice - it's extremely fussy.
With Partition Magic and
Volume Manager
still completely non-complaint with Server 2003, the only way to reduce
the partition would be to delete it, re-create it, and restore from backup
- and if I'm doing that, I could simply delete the entire RAID volume and
re-create it with the additional disks anyway! So, in the short term, I'll
mount a completely separate, non-redundant IDE drive into the server to
hold the new data, and cross my fingers that it doesn't fail! In the long
term, I'll have to spend another tedious weekend watching data stream to
and from tape - even with LTO drives, I'm looking at about ten hours for a
full backup and restore...
Unfortunately, this completely echoes the experience I
had with an earlier generation of Metastor/LSI hardware a couple of years
ago - in both cases we've been assured that dynamic volume expansion was
fully supported, but in the event it turned out to work only under the
most precise, ideal circumstances, rarely seen outside a test lab... I
love their hardware, but their
management software sucks donkey...
I don't mind a bit of weekend work at the moment,
though, as the overtime will help to pay for
this: |
|
It navigated me home from work quite nicely, today,
even coping remarkably well with the massive A13 road restructuring that
has been going on for the last few years. Full report when I have a spare
moment - probably around the time it becomes obsolete, at this rate... |

So, it looks as if Amsterdam's famous coffee shops are
finally to be
legislated out of existence - not in any direct attack on cannabis
use, but instead as a side-effect of legislation designed to protect
employees from passive smoking in the workplace. The era ends not with a
bang, then, but a whimper!
Elsewhere, Amnesty International's annual report says
that the US Government's "war on terror" has actually made the world in
general less safe
for ordinary people, as well as distracting attention from all the
other counties guilty of human rights violations:
"What would have been unacceptable on September
10, 2001, is now becoming almost the norm," Amnesty's Secretary-General
Irene Khan told a news conference. "It is vital that the world resist
the manipulation of fear and challenge the narrow focus of the security
agenda ... the definition of security must be broadened to encompass the
security of people, as well as states."
Closer to home,
another letter! Just like buses, evidently, although with
two in one week they're more frequent than any public
transport, locally... |

With the recent addition of the
Advanced Camera for Surveys package, The Hubble Space Telescope
continues to out-perform all expectations. The program's initial images
are a set of ultra-distant shots taken more to test the camera than as
"real science", and among them is the planetary nebula
Henize 3-1475. This memorably-named object is a shell of gas
surrounding a giant star, and together they seem to be acting as a
cosmic lawn sprinkler, spraying out jets of material in a rotating and
oscillating pattern. At around 2.5 million mph, the jets are significantly
faster than expected, and the mechanisms that could cause the complex
periodicity are not as yet clear... Equally thought provoking, and equally
spectacular, are the other images on the recently re-launched
hubblesite.org, an archive of the best from the HST together with a
wealth of background information and explanation. I went straight to the
exotica section of the gallery, which has some really cool stuff - a
set of six images of incredibly distant quasars, for example, each at the
heart of a different type of galaxy. I also noticed an image of the fine
structure at the heart of the remarkable
Crab Nebula, showing a fractal detail obviously identical to
small-scale life forms, or blood vessels, or mineral deposits in rock...
It's spooky stuff, when you think about it - one set of rules for
everything, from top to bottom... The physical processes of the universe
are extremely efficient with use of information. |

I heard a depressing statistic on the television news a
few mornings ago - according to various surveys, half the adult female
population of the UK have never been given flowers, only 13% get
them even once a year, and apparently more people send flowers to
say "thanks" than to say "I love you". How very sad...
Ros's satphone is working very well, as I've commented
before, and as the reliability of the other comms methods has been
relatively poor, she's used far more of her 400 prepaid minutes than we'd
expected. While checking out how to top-up her Iridium SIM online I
glanced at a chart displaying the savings offered by the 3rd-party airtime
provider we're using in comparison to British Telecom - ever dubious of
this sort of thing, I decided to check with BT themselves, but rather to
my surprise the claimed saving of at least 40% is actually on the
conservative side!
This has me fuming about bloated corporates all over
again, and as bandwidth has been on my mind recently BT are right in the
middle of my sights - they still have a complete monopoly on the local
loop, OFTEL is still bending over backwards to protect them, and even the
token gesture towards a level playing field in the form of exchange
co-location was made so awkward and expensive that only one bandwidth
provider, Easynet, has dared persevere.
It's been like this all my life, it seems - I'm
remembering the "good old days" of home computing in the late seventies
and early eighties, when BT-approved modems were both less technically
advanced and more costly than their unlicensed competition, thanks
to the huge time and expense involved in BT's certification process; and
BT's own products, bundled with their embryonic dialup service Prestel,
were the least advanced and the most expensive.
All through the eighties I kept hearing incredible
statistics about BT making profits in the order of a million pounds a day,
and yet where did this money go? Not into improving the national comms
infrastructure, certainly, or we'd all have fibre to our doorsteps instead
of rotting copper and even aluminium... and not into a subsidised
tariff, either, or they wouldn't want to charge me £3 per minute plus VAT
to phone abroad... Even chairman Peter Bonham's outrageous salary,
stupefying bonuses and lavish golden handshake wouldn't have made much of
a dent in that sort of income! It's a bit of a mystery, really, especially
considering that these days they're claiming abject poverty again... Oh,
well.
[Later] Ros used the satphone again, today, to tell me
that she was "calling from coitus interruptus" - a line she was evidently
very pleased with, as at the time she was
deep in Amish
Country, in the middle of Intercourse, PA... Talk about a
debasement of technology. :-) |

Hey, it's the
30th birthday of Ethernet, today! A toast to
Bob Metcalf,
then, whose brainchild has caused me a lot of head-scratching in the
course of an IT career spanning two thirds of the standard's lifespan...
and with
Cisco forecasting 40Gb Ethernet within the next two years, and 100Gb a
while after that, there's no sign of an end in sight. That certainly is a
lot of bandwidth, but unfortunately the pipe tends to become exponentially
thinner the closer it gets to the commercial end-user, and with the
apparent
failure of metropolitan Ethernet in the UK and dreams of fibre to the
home desktop evaporating in the face of BT's ridiculous "Midband"
offering, it isn't going to make any difference at all outside of carrier
backbones and the most demanding corporate networks.
Now
here's a
cunning thing - a hardware keystroke logger that can be interrogated
later without drivers or utilities - it recognises your password as you
type it into a text editor, then generates menus and returns information
by dropping the appropriate characters back into the keystream heading
towards the PC. Very clever, and very subtle... Actually, there's a whole
bunch of neat stuff in the ThinkGeek
store - it's grown a lot since I was there last year, and is definitely
worth browsing through. |

Another busy day at the silicon face, but with some
interesting news... I've been suggesting for a while that the
semi-independent network run by our leasing subsidiary should be evicted
from it's legacy DEC Alpha hosts and
re-housed on something new and shiny running Windows, and it looks as if
the powers that be have finally started to listen and agree. With the
remnants of the defunct R&D department about to relocate onto my LAN, it's
another step towards total control of the company's IT... Recently
I've even had the first official hints that the core databases running on
the time-shared mainframe will be moved in-house in another few years, as
well, which will give me complete power over everything.
Muhahaha! <coughs delicately> Excuse me...
Elsewhere, I'm just finishing
Wheelers, by

It's nothing staggeringly new or original, but was extremely
enjoyable all the same - between them they've created a fascinating alien
ecosystem in the atmosphere of Jupiter, and the most eyebrow raising way
of travelling through the solar system in a hurry since John Barnes'
wonderful Mother Of Storms. They're not dissimilar books, now I come to
think of it, and both are well worth a read.
Oh, and there's a
new letter - problems with Windows XP and the
Kingbyte KU5-In-1 USB card reader that I've just retired in favour of

Aaargh... Work was a bitch.
My PFY is off on a Checkpoint NG firewall training
course (an excellent upgrade from our current FW-1, he tells me) and in
his absence it was full-on panic interspersed with one annoying chore
after another... Eventually I managed to ruin the head of a cheap mounting
bolt while moving some switch hardware around in its cabinet, then snapped
the tags on its cage nut by hurrying and trying to force it - that lost me
an hour while I hacksawed the head off in situ, gained me a nasty cut, and
did not help my frame of mind one little bit. To make matters worse, after
much fuss and annoyance I finally managed to convince Demon that I'm
authorised to manage the overfilled POP3 mailbox, and
persuaded them to clear out the oldest mail, only to have it make very
little practical difference to the horrendous server problems... It has
not been a good day.
Fortunately an old friend is coming over for an hour or
two, and we shall have fun catching up and talking techie... Just what I

So, I'm now officially a senior network analyst,
with my own team of two techies and a DBA. One of the techies doesn't
actually exist as yet but, unlike the previous contenders, the applicant
we interviewed today actually understood my nasty-bastard interview
question (issues with WINS over a router to a multi-homed server!) and
even stumbled towards the general area of the answer! We've short-listed
him, along with one other, to come back and be grilled by HR and the IT
department manager, and with luck we'll have one of them onboard in
another month or so.
Although my office network is well protected again the
current Fizzer virus,
it seems to be causing major problems on IRC, connecting to a random
channel and generally causing mischief. However, once it was discovered
that the virus is designed to visit a particular Geocities address every
day to check for updates, a possible solution occurred. The Geocities site
was obviously intended to be an emergency measure and the virus writer had
not reserved it in advance, presumably to avoid linking himself with the
code unless absolutely necessary. This enabled an enterprising IRC channel
admin to claim the site and leave his own instructions for the virus to
act on, and although the initial attempt to force it to uninstall itself
from the client PC failed, the way is still open for a second,
better-planned attempt. Unfortunately it seems
that this would
not be advisable, as thanks to various US computer misuse laws,
specifically the Computer Fraud and Abuse Act, the action of uninstalling
or disabling the worm would constitute unauthorised access to the infected
PC and so would be as illegal as planting the virus in the first place -
possibly more so, given that the virus writer, if found, will almost
certainly come back with one of those ridiculous "oh, I didn't mean for it
to escape" defences. That was a valid excuse for
rtm's original worm and the
IBM christmas card, back in the eighties, but by 2003 it's merely
laughable - and the programmer of any future anti-virus code wouldn't even
have that slim defence to fall back on! It's an interesting
situation, for sure...
Elsewhere - apparently truffles can now be successfully

it's certainly guaranteed to shake up the food snobs... |

It's been a frustrating day struggling with email
servers... One of our ISPs, UK stalwart Demon Internet, has been having
extremely serious problems with its POP3 and webmail systems over the last
few months and, as they are Ros's primary mail provider, this has been
causing some difficulties. To make matters worse, in one of my usual
belt-and-braces decisions her laptop's mail client was configured to leave
mail on the server, and after a month of this her mailbox has grown to
31Mb... Hardly critical under normal circumstances, but given Demon's
current server issues it seems to have become enough to bring the entire
process of reading mail to its knees... timeouts, mysteriously locked
mailboxes, bogus authentication errors and disappearing servers abound,
and she's been effectively locked out of her email for the last couple of
days. She does have an alternative ISP, but a strange SMTP authentication
issue that she's never been in one place for long enough to debug means
that she can only send to other users of the same ISP - and that's really
only me...
So, hoping to save some hassle for Ros while we're
trying to persuade Demon to purge the mailbox themselves, I spent most of
the day trying to connect through their webmail interface to delete
whatever I could. Unfortunately this proved almost completely fruitless -
after several hundred connection attempts I managed to access the mailbox
maybe five times! Having finally persevered long enough to clear the first
page, almost every attempt to move onwards or to sort by date order
resulted in the connection dying, and every attempt to request more then
the default of twenty messages per page gave me a "server not found"
error... It's all been extremely trying, and as Demon are playing it by
the book and demanding all sorts of account details and security phrases
to purge the old messages, none of which I have, everything has stalled
somewhat. It's an awkward moment for it to happen, too, as she's moving
rapidly over the next few days and various people are trying to reach her
with contact details etc. Very frustrating...
Elsewhere, for those in search of the ultimate in
unusual weaponry, look no further than US custom gunsmiths
Birdman Weapons

With a product range including a Barrett M82 Pistol, a single-shot
cellphone gun, and a 300round 5 foot long "Giant Mag" for the Uzi SMG -
not to mention the .50cal nuclear bullets - they really do have something
for everyone! Fortunately, it turns out to be a spoof - but I looked at
several of the offerings with no more than a raised eyebrow before finally
catching on... take a
look... |

Well, that was an exceedingly stressful end to
the week... I got to the office early in an attempt to sort out the
horrible mess of modems left by our
almost-defunct R&D department, and was most of the way through
unravelling the spaghetti when all the
phones suddenly started ringing. Apparently we'd completely lost contact
with the fourth and fifth floors of the building, and when a thorough
check of the switches at each end revealed nothing, I started
investigating the infrastructure itself. Both primary backbone strands
tested completely dead, which certainly raised an eyebrow, but when the
four spares also showed the same state I was starting to wonder whether my
cable tester had failed instead! Having proved to myself that it hadn't,
and that all six cables had indeed mysteriously failed, I then had to
prove the same thing to my immediate manager before he took ownership of
the problem and let me rush back to finish with the modems.
Eventually it transpired that our cowboy electricians
(about whom I have complained long and hard, here, before) had been
commissioned to remove some obsolete coax from the second floor the night
before, and in doing so had somehow cut through the backbones
leading from the server room to the fourth floor. I have no idea how they
managed that, as the coax is thick, black and runs horizontally, while the
backbones are thin, grey and run vertically, but there you go... I've had
words with management about them on a number of occasions (the most recent
words were "dangerously incompetent", if I remember correctly) but have
been fobbed off. Maybe they'll take me seriously, now, and leave data
cabling to the professionals... Hah! And maybe pigs will fly...
Elsewhere, a report in the prestigious British Medical
Journal, claiming that the
risks of passive
smoking are significantly less than have been thought, seems to have
come under heavy fire - mostly on the grounds that it was partly funded by
the tobacco industry. Leaving
the data itself to one side, for the moment (although it does
seem to be unusually large and comprehensive, which makes it interesting
in itself) this seems to be to be an absurd argument. Firstly, it's quite
clear that large quantities of the overtly anti-smoking research has been
funded by the anti-smoking lobby, and this has never apparently been a
problem... and secondly because who else would actually fund research in
this area, any more? The health risks of smoking are now one of those
"everybody knows" memes, and don't attract much in the way of research
grants... As a smoker myself, I'm in no doubt that it's harming me, and
I'm still fairly sure that secondary smoking is probably harmful to a
degree as well - but nevertheless I'm still interested to see research in
the field, whoever spent the money to commission it.
Meanwhile, the
Ann Summers high-street sex shop chain
is suing to
force the government-run Job Centres to carry advertisements for vacancies
in their shops. The organisation has been prevented from advertising
through the Job Centres since a decision eighteen months ago that
vacancies in the sex industry would no longer be carried, and although I
thoroughly agree with the company's stance I'm nevertheless thoroughly
baffled by a statement from their lawyer, Kate Gallafent, who announced
today that "Ann Summers is not part of the sex industry". What exactly
are they, then, I wonder? |

So, if London succeeds in its
bid to host the 2012 Olympic Games, I could be paying £20 per year
additional tax for the next twelve years - or £25 for the next twenty
years, depending on who you listen to. So far none of the claimed benefits
have been of any interest whatsoever (so Sydney now has a plethora of
sports clubs after they hosted the Olympics? Well, gee!) and what with the
ongoing debacle over the Millennium Dome
I'm becoming increasingly disillusioned with any claims that the locality
ever really benefits from these projects. Whatever their lofty goals, they
usually just end up making a whole big pile of money for people that
had a whole big pile of money already. Bah!
Elsewhere, a recent report in
New Scientist magazine reveals
that real life is
actually more sordid and depressing than TV soap "Eastenders":
"Trawling back through 18 years of fictional east
London life, the magazine found that just two percent of the programme's
female characters and 1.7 of its men had an affair per year. That
compares to real life levels of 9 percent for women and 14.6 percent for
men."
The latter is an interesting statistic in itself -
given that it usually takes one of each sex to have an affair, if fewer
women than men are indulging, doesn't it mean that the ones who are
must be doing so with more partners, to compensate? Well, there you go.
Eek! Look at this...

Today's Epicycle is brought to you by the mighty
Steve Earle, with or without The
Dukes. I missed out on the whole
Alt Country revival until
it was well underway, and it came as quite a surprise to me recently to
discover that Earle was at the forefront of the genre. After growing up
with the sanitized, commercial Nashville sound somehow it had never
occurred to me that Nowhere Road was "country", and I bought
Exit O when it came out
in 1987, right in the middle of my heavy rock salad days, on the strength
of that track alone. Recent exposure to bluegrass legends such as Bill
Monroe, Lester Flatt and Earl Scruggs (via the wonderful movie O
Brother, where Art Thou?) has revived my taste for what is apparently
the "real" country sound, however, and I've been exploring a little
further...
As I'm on my own, right now, I don't feel embarrassed
to play the same track ten times in a row when a riff gets under my skin,
and it's easy to vastly over-estimate a song under those circumstances...
Nevertheless, it seems to me that Telephone Road, from Earle's 1997
album El Corazon, is
equal to any of Springsteen's small town angst classics. Like The Boss,
Earle somehow manages to leave no doubt that he's been the working
man of his songs, and after a few of these one feels an urgent need to buy
a blue denim shirt and join a union...
My brother Jimmy, my other brother Jack
Went off down to Houston and they never come back
Mama wasn't gonna let her baby go yet
But there ain't nobody hirin' back in Lafeyette
I'm workin' all week for the Texaco check
Sun beatin' down on the back of my neck
I've tried to save my money but Jimmy says no
Says he's got a little honey out on Telephone Road
It's a strong, industrial rock beat, with thumping
bass, rasping sax, a Hammond sliding up and down the chorus, and Earle's
powerhouse, moaning vocals driving over the top of it all... Very tight,
very bad, and deserving of significant volume - if this is country, sign
me up for the next tour of Dollywood.
Elsewhere, and while I'm in a lyrical mood - for Ros, a
line from Minneapolis band
Big Sky's
haunting Tuvan/rock fusion, Siberia:
And you are so far; still we see the same stars...
The track is available as
a free download along with
five others, and is a beautiful song indeed... |

The DEC hardware I salvaged from work has already given
rise to some peculiar moments, and the
final step, today, was no exception... This time I found myself
sandpapering down the plug of a SCSI cable so that it would fit into the
strange little aperture on the drive array's IO module. Removing two
millimetres of plastic moulding was sufficient to wiggle it into place,
and somewhat to my surprise it all worked perfectly first time. Not bad
for a server solution built entirely out of second-hand parts! |
|
 |
|
I managed to salvage five 9.1Gb drives and two 4.6Gbs
from the Microvax arrays and, once they're all formatted, I'll have a nice
34Gb RAID-5 volume for our MP3 library and a mirrored pair to hold the
server's pagefile. Now all I need is a server worth hanging it onto, but
as a quick look on eBay last week suggested that you can pick up a
full-loaded late-90s
Compaq
Proliant 1600 or similar for a couple of hundred quid I think an
upgrade may well be on the cards, soon - I used to run whole companies on
those boxes, and even though they're aging a touch these days they'd still
make a sweet
home server... |

So, in her resignation speech before The Commons MP and
ex-cabinet minister Clare Short
really flamed
the Prime Minister and the government, not only for the current secret
negotiations concerning the fate of post-war Iraq, but also for their
policies in general. It certainly needed saying, of course, but I can't
forget her years of
misguided
and
ill-informed campaigning against pornography and "Page 3" girls and
I'm still inclined to think that she's mostly a waste of skin...

I've just had an eyebrow-raising experience online - I
ordered some airsoft consumables from one of the big UK online retailers,
and then went immediately to the site of their main competitor. For some
reason I accidentally clicked the "show basket" link on the second site,
and to my surprise the items I'd just purchased on the first site were
already there in the basket! It was obviously a mistake, as the second
site doesn't even stock some of the things I bought at the first (hence
the need for multiple orders!), and some investigation shows that they
both use the same secure ecommerce provider. Presumably a session cookie
or something isn't expiring when it ought to, and although I can't
actually see any significant security issues arising I thought I'd spread
some of my IT misery around and so have mailed the webmasters of both
sites and the hosting company itself, together with screenshots and
logfiles. Enjoy your Monday morning, guys...
Elsewhere, it's been pleasant to spend some time with
technology that worked pretty right out of the box. The D-Link wireless
cameras slotted into the LAN relatively easily, and although the picture
quality currently leaves something to be desired in low light they're
quite pleasing little units. The LinkSys wired-to-wireless bridge was
equally easy to bring online, but unfortunately it has taken my last IP
address to do it - when Ros comes back home, I'll have to switch something
off to free up an address for her laptop! I wonder if I can persuade
Easynet to give me 24 IP addresses rather than 16, when I finally get
around to switching providers...

I've been so busy doing things that I haven't had time
to write about doing them! With all this time and attention spent on
acquiring airsoft, the computer technology has languished rather and I've
had something of a backlog. However, in bursts of activity over the last
few evenings I've managed to catch up a little.
I started by installing the
internal card reader
that I picked up for my main PC a while ago, and which was something of a
chore - the USB cabling was designed to connect straight to a motherboard
header, and I had to search out the
official specification
and re-wire the cable to attach to the internal socket on my Adaptec
DuoConnect card. Somewhat to my surprise it worked perfectly first time,
and as my soldering was a little better than I usually manage I've managed
to preserve a good enough signal path for full USB2 connectivity, often a
problem with homebrew cable assemblies.
While I had the case open I decided to re-arrange the
motherboard's IDE bus to separate the tertiary hard disk and the tape
drive - previously, when one was backing up the other the high bus
utilisation would slow the whole PC to a crawl, and after initial tests
it's now feeling a lot more useable. Having removed the two devices that I
was swapping around, though, I realised that the tape drive was now going
to be the the uppermost unit in the stack and visible through the top
window, so would need covering with black
sticky-backed-plastic to preserve the cosmetics. Unfortunately, the
drive casing is well perforated with air vents, so a tedious hour ensued
while I chased each one out with a scalpel - the constant risk of dropping
the little sticky cut-outs down into the tape mechanism certainly kept me
on my toes...
Still on the subject of technology, the
SCSI interfaces and cabling for the new RAID array
have been tricking in this week, and a further blitz at eBay netted me
another pair of
network-attached cameras, this time with an 802.11b wireless interface
as well as a regular UTP port, and also a
wireless-to-wired bridge to use with the existing Axis camera.
Total coverage... :-)
Back with airsoft, the
M870 arrived, as did the
JAC
Browning, and today the M1100 Defender shell conversion and a whole
stack of shotgun add-ons. There's more to come, still, but once it's all
here I'll take the three shotguns apart to mix-and-match between them.
I'll probably keep two of the resulting hybrids, and sell the third along
with any unwanted spares. <sigh> I'll probably have to risk the old camera
for some photos again, now - although the last attempt wasn't particularly
successful. Watch this space... |

Dead-tired, this evening, after a busy (but very
productive) day with the Microserfs. We drove down there in a director's
new Jaguar, for various reasons, which had an in-car GPS navigation system
that left me green with envy - a seven inch colour LCD built into the
dashboard, displaying an Autoroute-style road map when on motorways etc
but zooming all the way in at junctions to show the exact lane and
turn-off! Extremely slick, and a quick look around suggests that
portable
units are now available with much the same functionality... It's very
tempting...
Elsewhere,
as I rather expected, the New Jersey Assembly public safety committee
has
approved a bill that will impose a complete ban on airsoft replicas
and other pellet guns intended to look like a real firearm. If the bill is
voted into law, it carries an outrageous 18 month prison sentence for
possession and an incredible five years for supply! Unfortunately the NRA
are too busy with their own problems to campaign on such a fringe issue,
and the air rifle competition shooters don't use weapons that look even
slightly like firearms so won't care much, either - US airsoft is largely
the province of adolescents too young to own real guns and so I don't see
much likelihood of significant political organisation against the bill.
That will be a mistake for all concerned, though, as it feels to me very
much like the thin end of yet another wedge... |

The new
LCD monitor
monitor arrived today, and so far it's everything I hoped it would be -
slim, black and elegant (with a subtle blue power light to match the PC),
so flat that it almost looks curved the other way and, most amazing of
all, try as I might I haven't yet managed to find a single
dead or
stuck pixel! On a 19" panel that's a remarkable testament to
Iiyama's manufacturing quality, and
as the
official ISO standard allows at least three problems on a display of
this surface area, I think I've been extremely lucky. [Update: I found
one, stuck on in red - but positioned on the usual location for the
Windows title bar and I'm unlikely to notice it again without searching.]
I'm running on a pure digital connection for the first
time, as well, abandoning the analogue dongle on my Radeon graphics card
and using the DVI output thus revealed. It's hard to say how much (if any)
of the improvements in picture quality are due to this, and how many are
just due to the monitor itself, but either way I'm pleased with the
results. The whites are very white, the blacks very black, and all points
in between are apparently coloured appropriately. I shall have to tweak
the gamma a touch, as this particular display has a rather unusual value
of 1.97 in comparison to the PC standard of 2.20, but out of the box
it's certainly close enough for government work. A quick wander through
Unreal Tournament showed none of the ghosting effects that used to limit
TFT displays, and video streams seem to playback normally, and the bundled
Pivot software neatly rotates the Windows display, allowing the LCD to
be rotated to work in portrait mode should the need ever arise.
Although nominally the same size as my previous Iiyama
S900, the new display is measured in real inches and not CRT inches (the
bezel on a traditional VDU can hide an inch or more of the potential
viewable area, but nevertheless the value given is always the diagonal
size of the CRT itself) and so everything on-screen is slightly
larger. Hopefully this will bring a little less craning forward to read
small fonts - which at 1280x1024 can sometimes be very small indeed...
All the tech on my desk is now black or silver, with
the exception of my modem and keyboard. Fortunately Logitech do a slightly
updated version of my current ultra-flat model in black with silver trim,
and the modem can be swapped for a spare black-cased equivalent that's
been languishing in my desk drawer at the office.
Talking of the office, we're off to Reading to see
Microsoft, tomorrow, so that they can sell us on the idea of being the UK
pilot for Titanium, the imminent new release of Exchange Server. I don't
really need to be sold, of course, as the amount of consultancy and
hand-holding we get from these RAP installations is worth its weight in
gold, and to be honest I'd rather spend the day in the office catching up
on work... But I'll try to vacuum up as many freebies as I can to make it
worthwhile, if only to pass them on to my PFY - the long-awaited addition
to my network team has finally been approved, and he's currently suffering
a crisis of confidence at the thought of losing status to the newcomer.
I'll make sure that he doesn't - he has all the makings of becoming a
top-notch sysadmin in a few years time, and I want to hang on to him as
long as I can... |

I've been browsing through SCSI cards, today, to attach
the newly dried and rebuilt drive array to my little home server, and have
been surprised and disappointed to discover that the venerable Adaptec
2940U, my favourite workhorse for low-end SCSI, is still being sold
at a thoroughly unreasonable £160 and upwards... When I added in the cable
and terminator I'd need (no matter how many SCSI oddments one keeps in
stock, one never has just the right combination), then VAT and
shipping, the total could go as high as £300 - and for use with salvaged
hardware of uncertain provenance, that just wasn't an appealing prospect. |
 
|
A quick look around eBay, however, has proved extremely
fruitful - the going rate for a bare 2940 card seems to be between £10 and
£20, which is far more palatable, and so far this evening some crafty
bidwork has netted me a card and appropriate external terminator for the
meagre sum of £16.10. I also have bids on another card (just in case!) and
a cable, and with luck the final total will be less than £30 all-in - now
that's more like it! Adaptec hardware of that era is usually fairly tough,
so I'm not too concerned about buying second-hand, and with a pair of
cards to play with I'm confident of getting the array online with a
minimum of fuss. Well, a minimum for a SCSI installation, that is - any
project involving more than one SCSI device usually involves at least
some hair loss and extra frown lines...

So I was at the UPS package tracking site watching my
most recent airsoft acquisition winging its way over from Hong Kong, and
suddenly remembered the
old Simpsons episode where a Japanese factory worker coughs a pulsing
green cloud of germs into the box he's sealing up to send off to Homer...
I always like the official word on this sort of thing, so for the record
(as of today) here is the
official word...
WHO (World Health Organization), FAO (Food and
Agriculture Organization of the United Nations), and OIE (Office
International des Epizooties) have reviewed reports received regarding
SARS transmission. To date there is no epidemiological information to
suggest that contact with goods, products or animals shipped from SARS-affected
areas has been the source of SARS infection in humans. For the above
reasons, WHO does not at present conclude that any goods, products or
animals arriving from SARS-affected areas pose a risk to public health.
WHO will continue to closely monitor the evolution of SARS, in
collaboration with Ministries of Health and our partner agencies.
Of course, it pays to remember that WHO is a political
organisation above all else, and I wonder exactly how much proof of
significant risks would have to emerge before they took the drastic step
of recommending a complete suspension of all carriage and trade links with
infected areas...
Meanwhile, my long-term plans to buy an LCD monitor
suddenly seem to have advanced considerably - having poked and peered at
some rather nice (if over-priced) examples in PC World, this morning,
subsequent research online produced better hardware at better prices and
I'm currently awaiting delivery of a
19" Iiyama...
It's big, it's black, and it's high-tech - a built-in USB hub, dual
analogue/digital DVI inputs, and can be rotated from landscape to portrait
and back on the fly. Coo! |

I arrived at work this morning to discover that our web
proxy had suffered a power supply failure overnight (the fifth or sixth
time that one of our three Compaq ML350 servers has done this - obviously
a weak point, somewhere!) and that pretty much wrote-off the rest of the
day. As so often, our support company had one in transit to us in plenty
of time to meet our four hour fix contract, only for it to disappear
somewhere in the courier system and not re-emerge until almost the end of
the day.
However, this gave me time to pick over the DEC
hardware I'd salvaged yesterday, and I off started testing the little
three drive pizza-box SCSI cabinets with 9.1Gb drives salvaged from a
floor-standing equivalent. They just plain didn't work, even after much
swapping of modules, and eventually some hunting around online suggested
that maybe the pizza-boxes only supported 8-bit SCSI drives, while the
later towers supported 16-bit hardware as well. With six 9.1Gb and three
4.12Gb drives up for grabs, though, I wasn't about to let it drop and a
trip to the huge skip where the rest of the hardware had been dumped
seemed in order. Unfortunately, by this time it was around midday, and
with half of the company suddenly walking past the skip on their way out
to lunch, I suspect that I've confirmed a number of preconceptions about
the habits and behaviour of techies!
I managed to salvage what I needed in between fending
off various smart-ass comments, but it had been raining on-and-off all day
and everything was damp, to say the least, with a genuine puddle of water
in the drive bay... That won't necessarily be a problem, as
short-term dampness doesn't really harm computer hardware in the absence
of electricity, and as long as I dry everything very thoroughly before I
even think about applying mains power, I may well get away with
it... I'll strip it all down completely and stick it next to the boiler in
the basement for a few days, and maybe have a go at putting it all
together at the weekend - my home server would certainly appreciate an
extra 40Gb or so of RAID5 storage...
