Can't tell if you are trolling? I'd love to hear a credible source that says something on the lines of, "My understanding of the situation is that there is enough damage already done that a significant portion of the populati

Not sure how their antennas are constructed - if they are fabbed on a PCB, often at microwave frequencies you need exotic substrate material (e.g., Rogers) to cut down on losses. Those substrates are expensive compared to FR4 (fiberglass co

Exactly. Assuming 10 songs per CD, you should see your first collision after around 6500 CDs. If he did CRC64, it would be after 400 million CDs.

I feel like that sometimes too. I find going for a run at lunch helps a lot. It also helps my reality in check - when the weather is nasty, I get to go back inside after my run is done. That wouldn't be the case if I had to work outdoo

Undoubtedly there are really hard jobs. I'd put a mover on that list as well, along with oil field worker. But it seems dismissive to say a dev can't claim burnout because they aren't doing something physical. When a junior d

Yes, it is ultimately TT. The order goes: UTC -> TAI -> TT I could argue the TAI to TT is the second step. But let's put the pedantry aside: Is your best answer of something made easier in the modern world by leap seconds ensurin

I've spent a lot of time finding objects in the sky to high accuracy with astronomical algorithms. The first step is always converting from UTC to TAI. See Astronomical Algorithms by Jean Meeus if you don't believe me. Your noon e

Your article is about time zones, not leap seconds? The US has put forth a proposal to abolish leap seconds. It is now supported by China, Australia, Japan, and South Korea. The ITU keeps punting on actually voting on it - it's now sch

"UTC isn't flawed, in fact the adjustments that keep it aligned to solar time are very helpful for its defined use cases." What use case in the year 2019 is made easier by UTC getting leap seconds instead of treating it as a

How are leap seconds useful if you are an astronomer? I am genuinely curious what problem in the year 2019 is easier due to leap seconds. I have worked on code that needed to do astronomical calculations to do things like: position of sun,

Many questioned the SolarCity deal from the beginning. It was all over the financial news. There is also a shareholder lawsuit over it. https://tslaq.org/solarcity-lawsuit/ https://www.fool.com/investin

That doesn't really pass the sniff test... distance to GEO is 36,000 km, the sun is approx. 0.5 degrees in angular size, that would mean a mirror with a diameter of 314 km in GEO. We do not have the technology for that. 2 36000 tan(0.2

Yes, I agree the performance is an issue in most use cases, but wouldn't you agree there is value in there being parity between WebGL and OpenGL ES? It's valuable for those of us who work with Emscripten to cross-compile apps for

I have been wondering why WebGL isn't getting updated to ES 3.1 (and 3.2). Good to see at least 3.1 parity is coming: https://www.khronos.org/registry/webgl/specs/latest/2.0-comp... (I didn't k

Learn Verilog and practice implementing logic on a FPGA. A MicroZed board (Xilinx Zynq) is a great choice. You can even implement your own CPU.

Yeah that's true for the distributed application you mentioned with the wire. Certainly advantages there, especially when you control all the nodes. I hate seeing the fields of a communication protocol listed in two structs - an ifdef

This sounds interesting. Do you know of an example that does this? So if I have multiple threads reading the same mmap'd file, I use si_addr in the signal handler to know which page to call MAP_FIXED on?

I still think you shouldn't be directly sending structs over the wire or to disk. The alternatives are so much better - SQLite or Cap’n Proto. I'm a bit shell shocked from supporting both big and little endian in structs from prev

This. In my experience, I have seen parents who were in tradesmen encourage their children to get white collar jobs. A career that is physically strenuous and outdoors is no joke.

You should not directly use structs for data serialization. If you end up having to support a big endian platform, your structure orders will change, not to mention potential packing issues as you said. https://commandcenter.blog

I'm not really sure I believe this story. It's not like dumping a ROM from an arcade machine is as simple as dropping a cartridge into a copier. The ROM chips used could be custom. Often, the address lines were scrambled from stan

My memory was faulty - I did MIPS on QEMU to get big endian. The steps are here for posterity: https://github.com/kholia/mips-hacking

I got Debian for SPARC64 running under QEMU a few months ago. I wanted a big endian system for testing. I'll post the link on steps if I can find it. It was on GitHub IIRC.

Yep exactly. I'm talking about a pair of Prusiks to climb the rope. Of course ascenders/Jumars are even better. :)

Yeah for sure, injury changes things. You see rock climbers needing rescue often enough when they could have self-rescued by a pair of Prusiks and ascending the rope. I've heard of a rock climber using an ATC (rappel device) as an asce

It will still happen in a climbing harness if you are hanging in space. On a hanging belay, you try to get your weight off the harness and get your weight on your feet on the wall as much as possible. This alleviates the problem. Cavers wil
