... no expensive toy these days is presented to the public without mentioning how "green" it is. Never mind these toys are then bought by the stinking rich who then proceed to pack it in their landrover and head off to, say, the Pyrenees for a bit of "eXtreme biking".
If they'd really want to make a difference, they'd design a "green" utility bike that can be bought for not more than a hundred and fifty quid, such that also those of more modest means can make their contribution towards saving the planet.
... not so much the application code that programmers write, but the level of abstraction commonly used by today's computing platforms.
Say, as a practical exercise, one would want to emulate the computer used for navigation aboard Apollo spacecraft. One could choose to do this by using javascript running in a browser - a pretty sensible choice as a matter of fact. I'd bet that only a millionth part of the machine cycles would involve the actual computing, the rest would be eaten by the interface, handling events and painting pixels on the screen...
... was an excellent piece of kit. Especially the old (analogue) Optimod FM. It gave a station's sound *punch*, but it was the smoothest and sweetest punch I've heard yet.
Orban still makes makes Optimods, of course nowadays they're digital.
As a sidenote, building good compressor/limiters is a high art. Nowadays one can buy a two channel analogue compressor/limiter for a few bucks and they sound, well, reasonable... But top flight analogue gear (Drawmer, BSS) is still in production and commands premium prices, as do second hand units.
... on the dynamic range of phono cartridges.
A decent MM cartridge with a decent preamp would be capable of about 65dB of dynamic range, the limiting factor being the thermal noise from the cartridge's high-ish impedance.
MC cartridges on the other hand have very low impedance so the thermal noise generated by the cartridge usually isn't the issue. They have much lower output levels than MM cartridges so they require up to 20dB more gain from the preamp to get them up to line level. Which means that the noise floor issue (and thus dynamic range) is very much determined by the cartridge preamp's input stage.
Anyway note that a very good MM preamp does not necessarily cost a fortune. Regrettably, in "audiophile" territory there's very little correlation between a given piece of gear's actual performance, and its cost.
Of course, the performance of even a common garden variety MM cartridge can be heavily compromised by the quality of the vinyl. Virgin vinyl was (still is) costly, and in the early eighties, many labels used part recycled vinyl which included the paper labels and the occasional rodent. Brand new, full price LPs would sound like they'd been played a few hundred times with a rusty nail standing in for the stylus. Pressing waaaay to much records from a single set of matrices didn't improve things either.
On the other hand, I do have a few LPs from labels such as Windham Hill and ECM, and an OMR copy of Pink Floyd's "Dark Side of the Moon" that sound absolutely lovely.
... present on most Studer 2-track decks such as the A-80 is eminently suitable for this purpose.
Anyway, most recording studios had a set of small full-range speakers (known by their brand name as "Auratones") perched on the console's meter bridge, these were used to get a reasonable impression of how a mix would sound on an average compact stereo.
Also, I have modded a number of small ghetto blasters - fitted them with line inputs such that they could be used for similar purposes. Sometimes the mod cost more than the market value of the ghetto blaster.
Any reasonably informed person will probably be familiar with the placebo effect, which entails that in some cases a therapy that does exactly nothing will improve the condition of a patient because of the patient's belief that the therapy will be beneficial.
The exact opposite is the Nocebo effect: convince an otherwise healthy person (s)he's being exposed to your noxious agent of choice, and the person might actually fall ill.
Many of those who publish stuff on teh intarwebs about the supposed nefarious effects of cellular phone towers, nuclear power stations(*), fluoride in drinking water and so on and so forth, might be dismissed as mere wingnuts, but they might be causing more actual harm than the nefarious influences they so forcefully decry.
(*) Living next to a nuclear power station does not present significant problems since the radiation it emits is practically nil unless serious shit happens.
I wouldn't put my money on that.
Both machines are legacy hardware and came with XPHome originally. Which is pretty hard to keep secure these days. Botnets exist for a reason. The required AV software causes a huge performance hit, too (and is by no means a silver bullet).
Maybe, if my "converts" could afford brand spanking new machines with a Win7 Ultimate license... but I doubt this will happen in the foreseeable fututre. And certainly not "within a few months".
... the message appears to be getting through tho'.
I just "claimed" two "conversions" last month.
One, a musician whose kit (be it computers or guitar amps) I regularly fix, had me put Meerkat on a dual boot with XP when time came to rebuild his 4-year old laptop. Two weeks in, I inquired and he replied, literally : "Windows? Why bother?"
The other, a friend who had a spare machine for guests to use. The machine is a fairly modest PIII with a mere 256M of memory. The people who will be using it are a rather international lot. Ubuntu having the ability to change user interface language on the fly and being much less of a pain in the ass security-wise, a significant improvement over the machine's native WinXP. I settled on 10.04 LTS, but changed to the Xfce desktop since Gnome does not run well with less than 512M of memory. My friend was somewhat sceptical about Linux in general but after having taken the machine for a spin she was absolutely delighted, and I expect further requests for Ubuntu installations will be coming my way pretty soon ;-)
... 128kbps mp3's are sooooooo 2001...
These days for me it's either 256kbps VBR or better if I'm stuck with mp3, but I'd prefer lossless (flac or ape).
Anyway, a more interesting metric (from my point of view) would be : how many 10mpix canon raw files can be stored on one of those?
(answer: probably more than my beloved 400D could shoot during its lifetime)
... the root of the problem can of course be illustrated by executing the following SQL commands:
SELECT * FROM [civil_servants] WHERE [location] LIKE 'whitehall' AND [clue] IS NOT NULL;
(0 rows returned)
and
SELECT * FROM [civil_servants] WHERE [location] LIKE 'whitehall' AND [self_serving] = TRUE;
(server crash - result set too large)
... But the zircaloy tubes it is packed in, under certain circumstances, certainly are. If the fuel gets hot enough (through its own decay heat) zircaloy may oxidise very rapidly, i.e. burn. The reaction is strongly exothermic and thus adds additional heat to the system, which will further propagation.
Also note that the spent fuel pool of No. 4 (the one in trouble) contains a full reactor core's worth of fuel elements that have been unloaded from the core a couple of months ago (or so). These are quite hot both in the conventional and the radiation sense of the term, and if cooling fails a zirconium fire is not at all unlikely.
Such a zirconium fire will result in a white hot molten eutectic mixture of zirconium and uranium oxides, spiced up with fission fragments many of which are volatile at temperatures involved, and there will be no containment structure to stop these from getting into the environment.
A friend of mine got himself an Alpha 233 workstation back in the day, he used it for photographic rendering, the heavyweight architectural stuff. It ran Lightwave on NT4.
It was nearly an order of magnitude faster than top of the line Intel based machines or Macs.
It now sits in a corner in my lab, minus its Quantum Atlas SCSI HD (long dead) and its CDROM drive (ditto).
When I'll get round to it, that is, when I'll be able to locate the above two items at less than extortionate prices, I'll fire it up and put BSD on it, just for the heck of it.
From where I'm sitting, guardian.co.uk was painfully slow, with pages taking five minutes to load and often loading only partially, resulting in a jumbled mess. Ditto for Facebook.
It appears to have been a routing/DNS problem, and something to do with caching servers e.g. akamai.net.
Observing my browser status bar, I noticed that things ground to a halt as the browser tried to connect to static.ak.fbcdn.net. A quick search brought up a fix, it was suggested to use a ping/traceroute service such as ping.eu to obtain the offending server's IP addy, and include it in the machine's hosts file. This turned out to indeed solve 99% of the problem.
Same fix worked for the Grauniad, with the problem servers being static.guim.co.uk and combo.guim.co.uk.
I have to admit I was slightly flabbergasted, since I use opendns which is usually quite bulletproof.
... is that this malware does have a point:
Current AV software tends to be a huge resource hog and certainly affects a machine's performance.
On top of that, a lot of malware manages to escape detection by virtue of being new variants that the AV software doesn't yet know about. With said new variants appearing at an amazing rate, and there being a 24 - 48 hour window (my estimate)* before installed AV software can pick these up, AV software offers only rather limited protection from the dangers of getting pwned.
The best AV software resides between your ears.
"Do I really want to click on this?"
* the timeline being:
- new malware appears in the wild
- AV HQ detects new malware
- AV HQ makes database update available
- User updates AV software
...for speaker cables automatically disqualifies him/herself from being taken seriously when discussing audio gear.
The single requirement for speaker cables is that the conductor cross section be sufficient such that the series resistance can be considered negligible. For a 5 metre run, 2.5 sq mm is quite sufficient (having a total series resistance of about 0.07 ohms), even considering the fact that some of the more idiosyncratic speaker systems may have impedance dips as low as 3 ohms. Reactive effects (inductance and capacitance) can be safely neglected since the circuit impedance is very low, unless you're looking at *very* long runs. If one wants to be picky, one can use 4-conductor jacketed cable (with the conductors laid up in the shape of a square) so as to obtain a star-quad configuration. 3-phase mains cable works very well, and is very cheap.
Everything else (hyper-pure linear-crystal oxygen-free copper etc) is 100% hype. Copper used in run-of-the-mill electrical conductors is pretty pure as a matter of course, and the "linear crystals" are automatically obtained when the copper ingots are drawn to progressively thinner wire strands.
As a matter of fact, I dare anyone to distinguish the snake oil speaker cable of their choice from a run of suitably robust but very common and dirt cheap mains cable in a double blind test.
All those who worship at the altar of "high end" audio, I've got news for you.
The signals that make up your most prized recordings have travelled through tens of metres of cable that would cost a quid a metre at most, and often much less. On their way, they've encountered untold numbers of industry standard connectors that cost no more than a few quid apiece, and they've been routed through a truckload of top-of-the line recording gear whose signal path contains such diabolical things as op-amps, (gasp!) and electrolytic capacitors (aargh!). Lots of 'em.
Now ask yourself: Is spending 500 quid for a pair of hyper-duper "interconnects" with alleged magical properties, to carry the signal the last few feet from your CD player to your amp, really going to make one iota of difference?
... before one gets around to installing software that's actually useful.
On more than one I've had the, ahem, pleasure to deal with a brand new out of the box machine, and in each case, the plethora of toolbars, trial versions and thinly veiled spyware could have easily taken an hour or more to manually hunt down and remove.
So yes, on a new machine, Decrapifier should be the first thing you run.
I have heard, and investigated, such laments a number of times.
Turns out, that in most if not all cases, the cause of the mess is crappy formatting in the original Word doc.
Such as:
* Using spaces for indents;
* Repeatedly pressing the enter key (in other words, inserting empty paragraphs) to space paragraphs, or even
* Inserting a series of such empty paragraphs to get a page break, and last but not least
* Using fancy typefaces that may not be installed on the recipient's machine and therefore will be substituted by a default typeface, which of course may have different metrics.
A document formatted in this manner is an accident waiting to happen.
A correctly formatted document will retain proper formatting when exchanged between OO and MSO, and only in rare cases some fiddling might be required. Hint: there might be subtle differences in how MSO and OO handle "widows" and "orphans".
Bottom line: If you want your formatting to stick, not only between OO and MSO but also between different versions of MSO, *learn* *proper* *formatting*.
... until they actually get to see what it does.
Lots of casual snaps, maybe even the majority, tend to be portraits of some sort. Show anyone a portrait shot with DOF to infinity, and the exact same shot well-focused with shallow DOF - even complete noobs in photographic matters will tend to prefer the latter.
Decent compact cameras have a "portrait" preset for exactly this reason, and can achieve half-decent results. Mobile phone cameras cannot, because they have no optics worth mentioning, and since the tendency for mobile phones is thin - thinner - thinnest, it's unlikely they ever will.
"For most people, a good "snap" is good enough."
That's why "most people" do not use SLRs. Also because most people do not have the faintest clue about things like depth of field, "bokeh", and image noise (digital) or grain (film).
Those who don't think a "good snap" is good enough, do.
Well yes.
But this is done according to strict protocols learned by rote, and the conversation concerns matters directly related to the pilot's main activity. Furthermore, comms is half duplex while a phone conversation is full duplex.
Not quite comparable to dealing with one's mother-in-law while in rush-hour traffic on the motorway methinks...
Furthermore, the priorities are: Aviate, navigate, communicate. Which means that keeping the plane in the air and knowing where it's going takes precedence over comms.
