Sometimes it is the customers that need shielding from the engineers. I remember a situation where defcon was raised to 2 when the head of our unit found out that a particular engineer went to a meeting with a particular customer on his own

Stepper motors also have resonances that you can excite with typical step pulse trains, that can also lead to missed steps while technically not overstepping the torque budget.

IME all recent cell phones contain fairly strong magnets in their speakers. They tend to clog up with iron filings/dust in my workshop.

I wonder, if something "large" (like a neutron star merger) happened "just" before earth was formed, where is that large object now? It doesn't seem to be in our immediate neighborhood.

I think you either severely overestimate the capabilities of a C64 or underestimate what it takes to put a modern user interface experience together. The C64 had a resolution of 320x200 pixels with 16 colors. That would cover about 1,5 squa

SD cards used to be optimized for usage patterns typical in a video or foto camera (big files, written at once). eMMCs are better adapted to serve as a traditional filesystems for e.g. phones. Don't find source now though, so maybe I&#

Accelerated simulation of the effects of years in the vacuum and temperature of outer space on lubricants is non-trivial.

The exhaust temperature of the AC will be as low as is practically possible to remove a given amount of heat (assuming the AC is properly engineered). To extract energy from this exhaust you have the problem to remove heat from the cold end

OSINT is a contradictio in adiecto. Like a round square.

The austrian number says currently active cases are probably 2.5 times as much as official numbers. German study says in a community linked to an outbreak, there are 14% immune and 2% to be shedding viral DNA. Austrian study didn't inc

I don't think it is actually contrary to those other studies. The austrian study randomly selected among the whole population whereas the german study used a cluster connected to a hot-spot. IMO it is measures like social distancing in

They didn't really say asymptomatic or mild case, but presumably people with (strong) symptoms would have gotten a test and already be in the official statistics. The next study that is currently being prepared will include antibody-te

The results of a study in austria with 1500 randomly selected citizens have just been published, just 5 have been found to be currently infected with SARS-CoV2. The conclusion is that the prevalence of asymptomatic cases is about 0,32%, CL9

I think the only reason why top posting exists at all is outlook and an "optimization" in exchange where the replied-to message is referenced (not copied). Trying to reply in "proper" e-mail style in outlook wasn't

IMO this is deliberate mis-information, some type of info-guerilla, to stir and channel anger against the establishment.

And the Beaglebone runs what OS? Linux? The PRUs are just the replacement for the FPGA resp. microcontroller. You have your relatively relaxed control loop running at e.g. 1kHz on the main ARM and the tightly constrained stuff on the PRUs,

Linuxcnc on a raspberry pi 4 is fast enough to run the motion-control loop of linuxcnc with 1kHz, worst case latency is below 100us with current rt-preempt kernels. Generation of stepper signals or interfacing with servo amplifiers and enco

Every test in the real world shows false positives and false negatives. I would expect that doing multiple tests on a massive number of people could show such results.

> Quark is a made up word and has nothing to do with dairy. What on earth are you talking about? The german word "Quark" is a dairy product, "curd" or "curd cheese" in english according to dictionary.

Going faster than the speed of sound would be interesting and a somewhat "non-arbitrary" target.

I don't think it makes much sense to go smaller than the planck length (10^-35m) because probing smaller distances would create black holes. So in a sense position is quantized according to current understanding of gravity and QFT.

I wanted to check that out, but it seems the homepage at http://compilers.cs.ucla.edu/virgil/ is broken, the webserver doesn't include the server side includes (e.g. linkbar.inc, footer.inc)

Inkjets don't produce dust or ozone and usually don't need any startup time.
