Interestingly, Facebook doesn't seem to make unfriends too easy to find - they consider the greasmonkey script to be "abusive or spammy" and won't allow me to forward it to somebody within the fb message service.
still-image compression is not a field where large gains can be had so easily.
JPEG has two significant practical deficiencies which are not inherent in its lossy nature
I guess that the reason that something better hasn't emerged is the combination of the patent thicket around wavelets, and all the shenanegans the digital camera manufacturers have been playing with raw formats.
I think the question was meant to be "most recent to fail".
I struggled for a while trying to understand the question as it was posed and failed.
the question, as posed is as meaningless as "the most recent not to fail"
I was told about 10 years ago that "70% of the world's digital data is stored under MVS" which surprised me a bit, even then.
After some thought when you consider that almost all commercial transactions (banks, telcos etc) whould have been running MVS then it may have been true.
SETI and CERN and other large scientific endeavours are small fry in comparison.
using 64-bit integers instead of floats is a common trick in embedded C for control and signal processing on low power processors. I have experience of four different embedded systems used in commercial products from three different companies I've worked with - three of the four used 64-bit integers for roundoff-sensitive calculations.
I was a bit surprised that Matlab can't handle this, but then I've seen the poor quality of the ostensibly production-ready code that comes out of their M2C converter - it was about ten times the code footprint and a fifth the speed of a minimally-optimised C version of the same algorithm.
Honestly, I don't know how anyone can justify paying for this, when R (and even Octave in this instance) is more capable. Where the target platform requires C or asm code, then doing development in Matlab is usually more trouble than it saves. The graphs are prettier, though.
These days paper, as is used in laser printers etc. is not made mostly from wood. It is mostly made from bulking agents like calcium carbonate, which have to be ground to typically 2 micron or finer, and then dried at huge energy cost.
The wood fibers are just there to keep all the bulk together, and are a small portion (sometimes as little as 10%) of the weight of a sheet of paper.
You may have noticed that this sort of paper leaves a lot of ash when burnt.
Fine sand is a killer - it gets everywhere.
I used to work on powder processing instrumentation and regularly had to take laptop computers onsite to calibrate instruments. We used to use Dells with external IP-54 keyboards and masking tape over all the unused ports. On a few occasions I had to take a normal keyboard they didn't last more than a few keystrokes (I'd guess 20 per key before they failed).
This was lactose, coal, silica, calcium carbonate, etc. When we started work with metal powder we invested in proper IP54 laptops - no fan, membrane keyboard and rubber plugs on all the ports. Heavy, underpowered (800MHz PIII) but they worked. We looked at some "ruggedised" efforts but without the IP rating they were really just slightly less prone to drop damage.
but does it run Linux?
The only other half-decent stuff attributed to him are the 40th Symphony and the Magic Flute overture, also written in the three months whilst he was kicking the bucket. Makes me suspect that somebody else wrote them for him as well.
Having lived in the US, UK, Malaysia and France, I would concurr that the British plug system is far better. It was properly thought, and universally implemented across the country 50 years ago using an act of parliment on the premise that using anything else was dangerous and therefore potentially negligent. More features have been added since then (including household earth-leakage trip sensing).
I've had problems with a French pin snapping in a socket leaving an exposed live pin for my 3-year-old son to play with (luckily I spotted it in time and managed to cover it).
In the US I almost got used to the risk of shocks off electrical appliances. I also had a lab fire destroy some of my work because somebody had knocked out the cable of the pump supplying the coolant.
In Malaysia where the national standard specifies the british plug type, the biggest issue was that cheap Chinese imports sometimes didn't use it.
When basic safety is involved, I don't think that it's over-engineering. Your comment about extra points of failure doesn't make any sense.
Body temperature control is very effective in reducing the number of different enzymes that need to be coded for.
Frogs, for example have ~8x more genes than humans - partly because they have lots of different enzymes that do the same thing but at different temperature.
Or, Put simply, "No matter how slow it is, at least it has Adblock"
