I'm curious how they are going to handle the data processing of the radar return data. Past spaceborne synthetic aperture radar systems have generated enormous amounts of data that had to be recorded or relayed to Earth for processing into usable images and data products. Earth-Mars communication links are usually slow.
I used to run UNIX (AT&T System V) on my 80286 system. While being limited to 16-bits was a problem, too many people assumed "All the world's a VAX", it had some unexpected benefits. The liberal use of segments for code and data made the system trap many memory accessing errors that went unnoticed on systems with linear 32-bit address spaces.
Unfortunately, the CPU spent much of its time reloading segment descriptors. The C compiler was poor at optimizing memory accesses.
If you look at Intel's old literature, they assumed that people would be writing software in PL/M and Pascal for a Multics-like operating system. They weren't expecting the enormous popularity of C and UNIX-like systems that used large linear address spaces.
I thought most of them used Bell 202 modems, which are 1200 bps FSK. I salvaged some of them out of old credit card verification terminals for use with packet radio.
It wasn't "sheer dumb luck". NASA knew about the problem and gave it a great deal of study in order to quantify the risks. The solar flares of the magnitude that could have killed the astronauts are very rare events.
NASA has the responsibility, under international law, to deorbit HST in a safe and controlled manner. A random reentry, a la Skylab, in not considered acceptable these days.
HST does not have any propulsion systems. To deorbit the spacecraft, something would have to be attached.
Making a chip (the 286) with an enhanced 16-bit mode, but no way to switch back to real mode (fixed in the 386) which resulted in the 16 bit mode of the chip being nearly useless.
You weren't supposed to switch back to real mode, which was obsolete. They underestimated the PC industry's fixation on backwards compatibility and overestimated the ability of Microsoft and other software vendors to produce advanced operating systems. It was a decent chip, but it wasn't what most of their customers wanted.
You often need radically different algorithms to get the full benefit of SIIMD. The processing power is there, figuring out how to exploit it can be very difficult.
You can do a limited version of SIMD with an ordinary CPU. A 32-bit CPU can execute 32 "bit logic" operations with a single instruction. With a properly structured problem, 32 instances can be computed in parallel.
I expected them to bounce the check, or have a human examine it and recognize that the written amount of the check was a tenth of the amount indicated by the MICR. I did not expect them to program their computer to grab the money from my other bank accounts, and worse, not notify me that they had raided another account.
I never remember signing anything that authorized the bank to make unauthorized withdrawals from my other accounts in the event that there were insufficient funds to cover a check.
Beware! My checking account was grossly overdrawn, due to a clerical error in MICR encoding the amount of a check that I has written. Without asking me, Bank of America took the funds from another account of mine to cover the check. I found out about it when I received my next statement. They eventually restored the funds to my accounts. I no longer do business with Bank of America. They let their computers make all the decisions. It was only when I complained that humans got involved.
The article states that the charges were dropped "without prejudice", which means that they can be refiled at a later date if the prosecutor decides that it is in the public interest to do so.
Modern recording heads fly above the magnetic layer at distances in the ballpark of 10 nm. That's less than a millionth of an inch. There's no room for varnish or extra layers of stuff.
It wouldn't work. The gap in the magnetic head has to be extremely close to the recording media (magnetic layer) for it to be able to record and reproduce data.
Not only would the disc have to spin faster, the servo system would need to be upgraded. The servo system keeps the laser pickup positioned over the track and in focus while the disk is wobbling up-and-down, side-to-side, etc.
What about those little coupon printers at the checkout lanes in supermarkets? If I buy a box of brand X dog food, it will probably print a coupon for brand Y dog food. They have software that scans what I have bought and prints coupons from advertisers who want to target people who buy specific items.

The tradeoff is that if you design a rifle with generous tolerances for dirt and crud, you usually lose a noticable amount of accuracy.

The AK47 was designed to be reliable even if abused and neglected by its user. The M16 was designed to be reliable as long as it was properly maintained and kept clean. Two different design philosophies, with different objectives.
The Honda Civic was designed to be reliable. That means that the safety margins in its design are much larger than that of a Ferrari. Engines in mass-produced cars are often intentionally detuned from peak performance by the manufacturer. They trade horsepower for reliability and reduced maintenance costs.
If you want comfort, buy a Rolls Royce. They are incredible cars. Ferraris are not known for their low noise and smooth ride. That's not why people buy them.

NASA did the development of the Centaur upper stage and pioneered cryogenic (H2 and O2) fueled rocketry. They also did much of the launch vehicle development for Atlas, Delta and Titan, in between their initial development for the military and their eventual privatization.

A. Faster than the speed limit.
B. At exactly the speed limit.
C. Slower than the speed limit.
Pick whichever answer gives you reasonable suspicion at this moment.
They also tend to drive erratically, have dirty license plates and (crunch) broken tail lights.
Bullshit. Running away in fear, just because someone might use your actions as a pretext for a lawsuit, is for cowards.

All they had to do was place the satellite in the ESA zero-G test chamber. Oh, nobody has a zero-G test chamber.

IBM had a series of ruggedized/military derivatives of the IBM 360 that were labeled "4Pi". They were used by the USAF and NASA.
