I find that article to be almost unreadable. I recommend the original scientific paper instead, which surprisingly doesn't have a paywall: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1129381/pdf/wes

There's a good reason why 1 is not considered prime: it would break the property that numbers can be uniquely factorized into primes (i.e. the fundamental theorem of arithmetic). 1 is not composite either; it is called a "unit&quo

For datacenters, there are many design decisions for the power supplies and what voltages to use. The obvious solution is to use commodity PC hardware, so you have 120 volts AC to the computer's ATX power supply, which generates 12 vol

There was a similar story in comp.risks (anyone remember that?) back in 1986. When ordering a custom plate, you could put down three choices. The guy applying could only think of two choices ("SAILING" and "BOATING"). If

Wow, you're right; the results are very strange. Concentrations of 50, 5, and .05 have no effect at all, while .5 almost completely eliminated biofilm. That kind of looks like experimental error. Figure 1 at https://www.mdpi

The idea of Ask and Guess cultures seems reasonable, if the Asker will accept a no. However, it's easy for Ask culture to slip into Ask, followed by Ask again, "but why not?", "but you should", "but you did tha

Lumafield scanned a 1960s flip flop module for me, to help reverse engineer some vintage NASA hardware. The module contained a bunch of resistors, transistors, capacitors, and diodes, encased in a 13-pin plastic package. These modules had v

No, the latent heat of fusion is 143.6 BTU/pound, not 144. It's just a coincidence that the energy to raise water one °F ÷ the energy to melt ice is almost 144.

It's actually an interesting unit: a ton of air conditioning is equal to the cooling that you get from melting a ton of ice per day. It has nothing to do with the weight of the air conditioner. Presumably this was useful in the olden d

Number seven is miscellaneous issues; you need to click through to see them. One of the complaints is "treating data as singular". My view is that "data" is obviously a mass noun and treating it as plural is pointlessly

I was an (unpaid) technical reviewer for a Packt book on Arduino back in 2012. After a couple of chapters I realized that the book made little sense and was mostly plagiarized. It took more effort and conflict than I liked to convince Packt

Can anyone recommend a book like "Modern Processor Design: Fundamentals of Superscalar Processors" but more recent? I'd like to know the details of how current processors are implemented. Something like the next level after &

The title of the actual paper is "Some thoughts on security after ten years of qmail 1.0". The post currently has the made-up title "How to Write Software with Zero bugs – 25 years after qmail 1.0 – D. Bernstein [pdf]".

I'm happy to see Experian fined. Last year, Experian kept sending me spam with the footer "This is not a marketing email" and I kept trying to unsubscribe. Eventually, I filed a complaint with the Consumer Financial Protectio

You probably want https://c4model.com/ which explains what a C4 architecture diagram is. (See the first footnote in the article.)

I was pretty skeptical from the original article, since it totally seemed like correlation. But the study looked at directionality, that inflammation one week results in more social media the next week. The paper also describes other resear

I concur. You also had historical systems like the Four Phase, which split the CPU across 3 chips and the MP944, which used a small chipset. Not to mention that you can easily put a CPU onto a single chip nowadays by using a FPGA. The inter

The NEC V33 (1988) was a hardwired (not microcoded) version of the 286. The decision not to use microcode might be related to the long lawsuit between Intel and NEC over microcode. Also, as krylon points out, RISC chips generally don't

I'm hard at work tracing out the 8088 die, so hopefully I can confirm this discussion at the circuitry level before too long.

Well, I can't stop you from using a nonstandard definition :-) The original definition of superscalar from Agerwala and Cocke of IBM was dispatching multiple instructions to the execution units every cycle. This is the same definition
