On a quick scan does not seem to mention mercury delay lines which were a liquid memory technology commonly used in early days of electronic computing: https://en.wikipedia.org/wiki/Delay-line_memory#Mercury_dela... .

Yes, they buy these chips from fabs (made to their design) but it is the chips they then sell on, at about a 4x markup to what they bought them for. Good business model! Buy low, sell high. Whether good enough to justify current valuation

There is also the problem of thinking and problem solving at altitude -- we are much worse at it at high elevation compared to at normal elevations!

Very nice. In my experience much of the complexity of numerical software is to enable the search for the algorithm that works well with the problem/data you have. Once you know the exact algorithm you want, it is possible to make a nic

12 bits/word 60 words/minute 60 minutes/hour 8 hours/day 5 days/week 4 weeks/month => 7 Megabits => 864kBytes . Fits onto a floppy. What we could express as words, we could fit onto floppies.

NiX (and I assume Guix) are very convenient for this as it is fairly easy to turn frame pointers on or off for parts or whole of the system.

The documentation mentions GNU stow: https://www.gnu.org/software/stow/manual/stow.html This was very useful in early 2000s running shared linux machines with a diverse set of software for scientific applicat

For the Map Reduce specifically the one of the big issues was the speed at which you could read data from a HDD and transfer across the network. The MapReduce paper benchmarks were done with computers with 160 GB HDDs (so 3x smaller than ty

Horizontal scaling did have specific incentives when Map Reduce got going and today also in the right parameter space. For example, I think Dean & Ghemawat reasonably describe what were their incentives: saving capital by reusing an alr

This was nicely foreseen in the original Map - Reduce paper, where the authors write: > The issues of how to parallelize the computation, distribute the data, and > handle failures conspire to obscure the original simple comput

They do, but applications on these matters can easily overwhelm the financially weaker opponent. Interesting comment in one of the Post Office judgements: "10. Finally, disclosure is very expensive. The court will be astute to guard ag

Private prosecutions like this are specific to England & Wales (Scotland has a separate legal system where I believe they are extremely rare; Northern Ireland is also a separate legal system). While the incentives are not to reveal evid

The slowness of Python meant that nobody thought "it'll be easier just to write this routine" as opposed to looking to re-use existing (most often compiled) code. And if you are doing science, the less time you spend re-inven

The editorial is a little indirect but the funding challenge is the key bit. What the editorial is saying is that both the currently private projects in US to build the new generation of ground telescopes need government money to be complet

Nicely written. But isn't a corollary that we should stop exams in Maths (and Physics/etc/etc) degrees and just teach people who want to learn, how much they want to learn? Exams are for people designing bridges and doing sur

This is one of the reasons why Python got so popular. It is too slow to reimplement big pieces of software in it, so people just used bindings to existing code. And productivity rocketed!

Right, in principle they are better than just motion sensing since they can also detect breathing (and even heart beating!). And with modules costing 1-2$ people think... why not?

I've worked with a few people who started their careers on punch cards. I learnt: - Do not write a program if it does not need to be written - Think about what you are doing before you do it - Write with care and attention (whether cod

They are modular but not very interchangable (there are 133 different designs of the segments in the primary mirror). Making a much larger mirror would also face another obstacle: the focal length is designed to be practical for a ~40m mirr

My vague memory is that there was/is a military or government site nearby which is why the research centre is also there.

This seems like an FFT based benchmark.... I believe NumPy for licensing reasons includes a port of old FFTPACK which is only single threaded. (Py)FFTW or others are surely much faster. So the test seems to compare one thread of a CPU laun
