My wife and I recently converted every bulb in our apartment from
incandescent to these new swirly bulbs. It cost us around $150.00 to
convert all of them, with the logic that energy and replacement
savings would offset investment cost. She's a business woman, and I've
learned to speak her language.

We had recently watched 30 Days, a TV series made by the guy who did
Super Size Me, about energy consumption and the massive drop in
energy usage if everyone switched one bulb. We figured that only 1 in
20 American's would actually bother to switch one bulb, so we switched
all of ours hoping to make up some of the difference.

It's pretty amazing that you end up replacing 60 Watt consuming bulbs
with 13 Watt.

I used to heavily used fluorescents when I as a student (in the early 
1990s). I then found the technology interesting, and more elegant than 
incandescendents. Less wasteful, which appealed at the intellect level.

However, since then I found out I hated them. With a passion.
Fluorescents suck. Let me count the many various ways in which they suck:.

They take a tiny little moment to ignite, making little clonking noises. 
They take a while to get hot enough for the mercury (!!!) to evaporate
and reach maximum brightness, so you have to always think conciously
whether to let them burn, or switch them off. Each time you switch them on,
the life time is taking a hit. You can't dim them. They only do diffuse
lights, no spots. They flicker. No, not the kHz flicker, can't claim to 
see that, they start flickering visibly when they age. Which is very soon. 
Their spectrum sucks. They become dimmer and dimmer as they age. Etc.

Which is why I went back to halogens (about 1.3 kW worth of them, and in a
small household). I *think* (never used them for major lighting yet) 
I would like LEDs, but they'll probably take to be color-tunable, or at least
use simulated solar spectrum, maybe shifted a bit to the red range.

 convert all of them, with the logic that energy and replacement
 savings would offset investment cost. She's a business woman, and I've

I'm a light nazi. I need really bright lights everywhere, and dimmable, too.
I wouldn't bother under multiple 90 W of fluorescents, which is OP-room 
bright. Except you couldn't dim them, and they would burn out my photorhodopsin
in no time at all, and I would look like Malkovich, except without the many

[silk] open sores

2007-02-20 Thread Eugen Leitl

Maybe you remember my question about a bank account API.
Well, I finally got HBCI (FinTS, nowadays this would a 
no-brainer XML over SSL, but this is a braindead legacy
protocol, albeit encrypted) to work with aqbanking.
Behold my tale of woe.

The epic story behind it: this is something I've been trying for
years. Attempted it about 10 times, and each time gave 
up. Messed up an operating system in the course of one
such setup (when upgrading to unstable branch, where 
packages are fresher, but where be dragons, too).

It's a simple command line application, available in
the Ubuntu package depository. The documentation is really
bad. Not just nonexistant: there are too many different
documentations for different versions (and names) of the
package in question. Still, I tried, and actually created
a key set, and submitted it to the bank, and verified 
(out of band, via passing a clerk a piece of signed dead tree
with hex numbers on it) my public key (fingerprint). Try
to connect to the bank to receive a list of transactions, no
go. Search long and wide, find a report that Ubuntu packages
are way out of date. So far, nothing new.

Look for new packages, only source available. Don't want
to mess with building Ubuntu packages, attempt a straight
tarball install. Configure complains I need a newer library
version XY. I pull in the library, and also build it from
tar ball. That library has a different dependancy, I also
resolve it that way. Hey, I'm lucky, just three dependencies.
This is way unusual.

Attempt to build the new application (remember, it's a plain
command line interface), and it asks for qt3, kde, and libofx.
I howl, comply, and pull in some 100 packages by way of codependancies.
It's a frigging mess, but it happens to work, in the end (this time,
it didn't the last time I tried). I send the
developer a donation, because though a) it was intensely painful,
2) it worked, and I absolutely need that piece of logic working for
a user account/shopping cart infrastructure.

The problem is that my experience is typical for an open source
package. Tale of woe ends here.

 There are even reflector bulbs that can replace conventional floods -- 
 not such good focus yet as to replace spots though.

I actually like metal halides for the spot. Normal halogens not nearly
aggressive enough.
 
 For a 72% reduction in power consumption (and waste heat), I'll live 
 with that half-second hesitation on turn on. The money side certainly works.

I run a rack full of hardware, which is about 30-40 EUR worth of 
electricity/month.
The lighting part doesn't even register on the financial radar.
 
 As for LED lighting, it's just now coming on the market, and so far it's 
 outrageously expensive, like $48 for a 50W incandescent equivalent. 

Yes, but the best stuff in the lab is twice the lumen for watt of fluorescents.
And still rising...

 OTOH, it promises even greater power savings, the ability to not only 
 dim to zero, but also to adjust the color balance. Might be a few years 

My point precisely. Also, they're not diffuse, but can be made diffuse.
My halogen floolights are directed at the ceiling, too.

 before it becomes cost effective, but the possibilities are intriguing, 
 especially as it doesn't *have* to be built as screw-in replacements.

I'm thinking about linear LED assemblies of flat panels. LED wallpaper,
preferrably.
 
 An example of this last point is seen where I work. Step lights (small 
 fixtures mounted in a wall to light stairs) are used all over. They were 
 originally installed with 60W incandescents. Five years ago, we began a 
 program to replace them all with 11W compact fluorescents -- with the 
 same color balance. You couldn't tell which a given fixture had without 
 taking off the cover. Now we're starting to replace them with LEDs, but 

Maybe I have a special retinal receptor for fluorescents, just like 
tetrachromate mutants. I can always tell, and these things make me
want to smash them in instantly. Probably a direct neural pathway
to the amygdala... 

 instead of screw-in devices, the LEDs are mounted on a PWB so they all 
 point in one direction and are hard-wired to the AC, eliminating the 
 socket as a failure point. They also are color matched to the 
 incandescents, they draw only 4W per fixture. Not a bad improvement!

electricity/month. The lighting part doesn't even register on the
financial radar.


I must have more sensitive radar. Or maybe it's just my wife's monthly 
scrutiny of the bill. Or maybe it's the A/C that brings the monthly rate 
up over US$200.




As for LED lighting


I'm thinking about linear LED assemblies of flat panels. LED
wallpaper, preferrably.


Parallel thoughts. I've been working on a low-heat, zero-UV, LED 
lighting system for museum displays. Still too pricey, but the 
technology is getting closer every year.


Any vendors to recommend?

Did the computer term semaphore come from train semaphores? I have
always assumed so.

 Rail cars will indeed provide an adequate current path to shunt the rail

software.  (indeed, failure to observe a proper semaphore system leads to
crashes, in either field)

(WWI is one of those wars for which no one has any good excuses as to why
it was started.  One of the stories is that after the order was given for
mobilization into belgium (because it was widely believed at the time that
the road to moscow went through paris), the kaiser was about to change his
mind, but was convinced that the logistics of deployment were so intricate
that there could be no undo.  Years later, after all the destruction,
the guy who'd been in charge of the railroads published a book full of
charts and graphs and timetables to explain how, in fact, the order could
have been relatively easily reversed, had cooler heads prevailed)

And since it's been a while since I've pedanted about etymology on the list:

Semaphore, liketelegraph is a compound word irregularly formed from two 
Greek roots: 'sema' = symbol (as in semiotics), and 'phoros' or 'phoreus' = 
carrier/bearer (as in phosphorus).

Possibly - though semaphores stared out as a military signaling system (in
France, about the time of the French revolution, if I recall correctly).
Other countries soon adopted it - and the name of Telegraph Hill outside
London dates from the period that an 'optical telegraph' signal tower stood
on it.

You may recall an episode in The Count of Monte Cristo where the eponymous
count tricks de Villefort into bankruptcy by bribing a semaphore signaler to
send a false report about an impending revolution in Spain?


Sure I understand how semaphores were used as a general purpose
signalling mechanism, but it was from their use as excusion flags for
trains (as Dave mentions above) that I thought the name (and
semantics) were borrowed for computers. Anyone know for sure?

I can second that - it's usually my back, my attention span, or my
wrists that give way first, rather than heat, with my thinkpad.

My Powerbook G4 is not bad either, though I'm worried that the battery
will blow up any moment. It's on recall, and I've been promised a new
one for the last six months.

I'd say it was highly probable - seems logical, doesn't it? I don't know who 
created the use of semaphores in concurrent programming, but the use seems 
analogous to railway signaling for traffic management...

Are semaphores still used in OSs? Thought they'd more or less died out...

It's certainly the AC. I switched the whole house to CFL two years ago -
about 40 bulbs. There's been no observable difference in the bills.

But eight months a year here it goes above 40 degrees celsius, and the
electricity bills drop to about 30% of their summer peak in the other 4
months.

I ended up buying an IBM thinkpad for the same reason

quite true, they are better than other lap-tops in that respect,
i use a T42  my friend owns a latest T60 but what i have noticed is that
newer T series(T60) ones(read Lenovo laptops) get much hotter than the T4x
series(T42,T43  they are phased out now) which was the topmost seller in T
series when IBM owned it,


did anyone else noticed the same too..or is it just me seeing (rather
feeling) too much into the change in thinkpad brand owners.

Not true. I have had a T21, T42 and a T60. The T60 is about as hot as
the T42.
