Re: Alistair becomes Aristide
Forgot to add, Aristide means “the best”.
Congrats to Mr. Dabbs.
Alistair is a variation of Alexander (the Great?).
Very good in either case, as us commentards who diligently follow Mr. Dabbs already know.

“ low-cost optical aperture which can utilise all infra-red wavelengths in the C band”
My understanding is that C band is in the centimeter range, with 7.5 - 3.75 cm wavelength.
IR is from ~700 nanometer to 1 millimeter. Far IR is roughly in the micron range, something like <100 micron wavelength.
And never the twain shall meet?
Anyhoo, IR is good for cooking bacon.
Seems to me the whole point of getting new screwdrivers is that the old ones have worn tips, why would you wear down the tips of the new ones?
If you are an ocd type like me, you can even make a jig for the hammer smacking, so that the dent on the lid fits the one on the box itself.
I resemble that! There is a big difference.
Being disoriented means that there is a correct direction, it’s just that you don’t know which one is correct, at least temporarily.
Being a scientist (and I consider myself one), most times it’s not even clear that there is a correct direction out of the predicament.
Size matters, because the smaller the machine, the more roughness of the surface will be impediments. That’s why lunar & Mars rovers have large diameter wheels.
How do they expect it to move around on the rough surface of the moon, where ~80mm pebbles and lumps and bumps are expected to be commone.
Or did I misread the article, and it’s not supposed to be mobile?
White dwarfs have ceased nuclear fusion, hence dead.
They remain luminous as they cool down from the extreme temperatures (1E7 K) reached at the end of their fusion lives, much like a heated lump of metal remains luminous for a while after being withdrawn from the heating source.
I feel inundated if not intimidated by all these date formats. Many of them predate / antedate the modern era, so why shouldn't we just invalidate a whole bunch of them, consolidate the remainder, select a very few as candidates that accommodate the most widespread current usage, elucidate which of this small subset gains widespread adoption, and mandate its usage?
It would make life much more sedate.
Used to navigate using LORAN, it’s simples triangulation, and surprisingly accurate, will get you to within 10’s of yards of a spot in the middle of the ocean (well not quite, but anywhere off the coast within reach of the LORAN signals). Sadly, all the newfangled tech resulted in the LORAN stations being turned off for cost savings.
That dredged up a memory of long ago. During a lecture, a student who had to be absent got permission to put a cassette tape recorder (yes, that long ago) on the table in front of the room, to record the lecture.
Next thing you know, other students started doing this, to avoid attending.
They then decided to jibe the lecturer, by all of them skipping the lecture, so that the lecturer would be faced with a mass of recorders, and an empty room.
Except that the lecturer got wind of this, and when the students arrived to set up their recorders, the lecturer had already put his cassette recorder on the table, with a note that said “Press Play to start the lecture”.
I find it annoying the way they cute-tify space probes, by anthropomorphing them (perhaps to reach a younger audience?)
NASA does it, and Japan is doing the same.
“Ooo, look, I farted some gas to change my course to the asteroid”, “My bad, I used non-metric units and completely missed my target”.
They are machines, designed by us! (Us, meaning talented humans). We can celebrate those who designed, built, and operate them, without needing to resort to baby talk.
For all this involve in the mission,kudos!
Oh, to live on Sugar Mountain
With the barkers and the colored balloons,
You're the product on Sugar Mountain
Though you're thinking that
you're leaving there too soon,
You're leaving there too soon.
It's so noisy at the fair
But all your friends are there
And the candy floss you had
And your mother and your dad.

Geez, now you've dredge up a memory I tried to suppress all these years. I once used a language (BASIC? On the Apple II? Fortran on the IBM 1130?) that insisted that constants start with I, J, K or something like that, while the other letters are reserved for variables, or some such nonsense (yes the memory is still somewhat suppressed).
Given my handle, I felt that I had to make a comment.
First,: De gustibus non est disputandum.
Second: I consume about 5 lbs (2.25kg) of meat a week, go figure...
We presume that the planet Mars is the reference in the manfrommars handle; what do you call someone from the Vega star system?
That’s the case for most users, but I have genetic analyses that are highly parallel, so more cores scales better than more clock speed.
For example, one of my jobs would typically take a month or so, using all 24 threads of a 12 core machine, running 24/7. I would love to have a 48 thread machine, because it should almost halve the time of the run. It is much harder, and gets into impossible territory, to scale clock speed in a similar way: A 2.5 GHz chip could possibly be sped up to 5GHz, but 10 or 20GHz? I do appreciate higher clock speeds, it’s just that more cores gives me more bang for the buck.
When you get down to the basics, a GPU is a massively parallel chip, because much of the graphics task can be nicely parallelized. One can imagine (hope?) that other common tasks can better take advantage of getting paralleized to the extent possible. Modern OS’s already generate many threads, to take advantage of the cores available.
Almost a megawatt-hour per transaction?!!!
Here I am, switching to LEDs and adopting other power-saving measures, just to save a few kilowatt-hours per year...
Bitcoin is an ecological disaster in addition to all the other bad things they say about it.

On the face of it it, the observation that fake goes farther than non-fake says that the twats, at least in the aggregate, can and do know the difference, and treat the one differently than the other.
Being more inclined to pÉ¹ÉÊoÉ snoÉ¯ÊuouÉ's point of view (how stupid the average person is, etc.), I wonder if they analyzed if there is a distinct subset of twats who are responsible for most of the fake re-tweets.
