That's the formal definition, and an interesting corollary with interesting consequences (from a typing perspective, a function of any return type can always opt to halt instead of returning. note that in a lazily evaluated language li

No. First, null is generally a value, not a type. Second, think of bottom types as "does not return". Taking C as an example: C doesn't have a bottom type, only void which is a unit type (it has a single value, which is anony

He said "The RAM needed for each container was very small" - the RAM is _not_ the limit here. The point is that running many containers is a very different (hard to compare directly) type of load than the main, well optimized use

Nice! But how do you tell that from strace? Wouldn't it just show the guests stuck in connect()? With perf, sure, but strace?

I don't think that's the most important part. Rather: Full disclosure can also protect previously unaffected / potential future customers, by warning them of companies that have been so lax with their security that they'

Spot-on! For the specific purpose of controlling APA102 via wifi, ESP8266 (NodeMCU or similar) seems optimal, as 1x SPI and WiFi are the only peripherals needed and so ESP8266 is a perfect fit hardware-wise, and it's well-supported, ex

APA102 is strictly better than WS2812B (standard SPI, much less sensitive to timing, way less PWM flicker, similar price/availability). When you still want bare metal, pick a modern uC like ESP8266 (cheap, 32 bit, integrated WiFi for t

It's never exactly 50 Hz, as the frequency is affected by load and generators can't compensate this perfectly. So record it in many locations, then correlate the signal extracted from audio/video against the database. Main ar

"The wrong reflection" doesn't give the right impression. The point a 100W laser projects against e.g. a wall, when viewed at 1m distance, can damage your eye. Even if perfectly diffuse. Even if invisible. I recommend taking

Nice project! Thanks for working on it! It would be great if there were more search filters. Especially size ("larger than") and date ("within x-y", "last 1 day/week/month/year"). And when you ha

For microwave ovens / water: You have cause and effect reversed. You believe water has an absorption peak at 2.4GHz because microwave ovens use it, not the other way around. In reality, microwave ovens use 2.4GHz because it's lega

Don't be overly pedantic. As inaudible to human hearing is exactly what the author meant, 0dB (implicitly relative to anything reasonable) actually matches the intent better. Also 0dB (relative to no matter what) is closer to the machi

Another example would be rapid descents: the aircraft can become quite unstable when it gets into its own downwash. (A high control frequency makes all the difference here for quadcopters. Compare a toy and a hobby quadcopter, it's eas

No, not at all. The technical difference is how the overall thrust is steered: * Quadcopter: the speed of four (fixed pitch[1]) propellers is managed independently. Spinning a single propeller a bit more tilts the copter away from that prop

Just naive, not arrogant (it's ok & encouraged to think through things yourself, even if there already is a solution. you can't expect to come up with actually new good things on day 1.). You've described the obvious part

Ham radio does not necessarily mean expensive equipment. It tends to get expensive, but with some knowledge about electronics, you can build transceivers and antennas very cheaply too - and after all, being allowed to do that is the main,
