Also, as I've said before in other contexts: What company and what people would build this 1960s technology? Many supplier companies don't exist and the knowledge that exists only in people's heads is badly eroded.
Given TACP's code examples are in assembly language (MIXAL), it's not too surprising that TeX's command language can be regarded as the assembly language of a virtual machine. Hence, macros, such as LaTeX.
Back in 1996-7 I wrote my Ph.D. dissertation in LaTeX. There was some weird page limit bug (briefly, one page too many kicked out an error), and I was really worked up about what to do until finding out the output (*.ps, IIRC) was _itself_ a macro language, in which case cut-and-paste on the page numbers, which stood out (at least to me), saved the day. Should have not happened; still, try salvaging that in almost any other system.
Regarding Energia, if that is indeed the case, someone was really dumb to let that capability go. Yes, I know things have been dicey both politically and economically for years, but this is a unique capability that could be marketed to those who need heavy lift, perhaps at a high price.
Yes, there are renewable hydrocarbon sources right now (I used to go to UCLA, which uses biomethane from a nearby old landfill to run a cogen plant). I was over-focused on what the parent poster said.
Trivia: how can you tell methane was recently generated? It has carbon-14.
Could tissue growth be suppressed locally, maybe by having a supply of some anti-growth factor dispensed from the (possibly porous) probes? It would still have to be replenished; but undesirable side effects (suppressing tissue growth elsewhere) could be eliminated or mitigated and the probes could last much longer.
Too bad they didn't have this a decade ago, when a consultant of my acquaintance took an early laptop out to an aircraft carrier via a small cargo plane (C-2 Greyhound). It worked on the boat but failed the next time it was booted up. Apparently the G-force ate the disk.
... as long as you use VAX/VMS EVE, which unlike emacs stopped at being a highly flexible text editor, and didn't try to be a virtual machine as well.:)
Not necessarily, there are other factors that limit food production. Also, a higher survival rate results in a growing population until people realize they're more likely to survive and cut back on the number of children they have. Education is critical in being able to comprehend this.
The 'new class' (atomic, molecular clusters) has been around a while, but only at near-0K temperature. This is the first 'room temperature' system I've heard of.
Aluminum is highly reactive; however, bulk pieces are passivated by near-instantaneous formation of an impermeable oxide layer, in air.
The article describes formation of aluminum clusters of some small number (13 or 14) of atoms which are passivated (made non-reactive) by some variable numbers of iodine atoms. The resulting cluster presents iodine atoms to the outside world and thus acts as a big iodide atom.
The shuttle uses a version of IBM's AP-101 avionics computer which uses the System/360 assembly language. (The mission computers of the ICAP-I version of the Navy's EA-6B aircraft also did, and I pawed through those all-assembler listings to port features to ICAP-II aircraft which had a different computer and C-like language). IBM quit making them so any new flight hardware has to be plug-compatible and code-compatible.
Right now I'm modding C++ for an AMD 186ES, an embedded system with 186-compatible core and A/D and D/A, and serial ports on one die (and shrunk to a smaller die around 1990).
A good high school level computer science instructor probably can't afford to live in the Valley, or much of the Bay Area (unless they live with their parents), for one thing.
Sounds similar to my situation: an abstract CS degree (in 1982) and more than the usual curiosity for low-level stuff. I ended up doing embedded work for the Navy, as a GS-855-12, Electronics Engineer, Computer Science Specialty.

Or, make sure the structure resonates at frequencies that a quake or windstorm would not drive.
Older tech is proven, but someone's got to make it. If your suppliers end-of-life on you, you're out of luck.
about which you can say the same things :)
Canceling this project means saving almost nothing compared to the hundreds of millions of dollars spent so far.
:)
So? Priorities have to be established, and by whatever criteria were used, this was a low one. It happens all the time.
I bet this thread was submitted by one of those sci-fi fans
Despite the company taking a one-sixth hit to their net, I wonder if the new business obtained made it cost-effective in the end.
There was a Mac app (OS 7 or so) that tied TeX to a GUI. I tried it and it was ok.

Why build a new one, when Russia already has one?

For now, yes. Long-term, when there are other ways of generating hydrogen, no.
As hydrogen flames are invisible, it wouldn't look like much.

Your examples are embedded systems, not the IT infrastructure that is addressed here. Embedded medical devices are subject to FDA review.
I used to write and debug C for a medical device company.
Arthur C. Clarke mentioned going over the poles to leave the ecliptic in "The Conquest of Space," a science book that came out around 1969.

Not just heavy, but broad-shouldered. I speak from recent experience on KLM/Nortwest DC-10s and MD-11s.
