The FCC and other government bodies (ITU) in other countries tightly control the radio spectrum to prevent interference. There are a few bands that are set aside for general use called the ISM bands (industrial, scientific, medical). In t

See the Tests and Research section of the following NTSB report on a Delta incident where a plane landed on a taxiway at KATL. Note Also that the lights had been recently updated with LEDs from incandescents. Basically, the taxiway center

There are lots of systems that break the reciprocity: https://arxiv.org/pdf/1705.09548.pdf from a few months ago has some descriptions. I think (not having read the Science paper) the issue would be that the underlyin

Cool project. It's much clearer than I would have thought in asm. The inline documentation is good.

I feel like writing a LISP in a gc'ed language is taking away most of the fun of it. I wrote one in C (without a conservative garbage collector) and the most interesting aspect was what had to be done to allow garbage collection. Garb

They apparently did recover the fairings successfully.

I haven't heard anything about it. They were also going to be testing the 'Roomba' robot contraption on the recovery ship. Best place I know of for news is probably the reddit r/SpaceX subredit.

Even worse than the expense of the payload is the time: some payloads take several years to build and some literally can't be replaced (e.g. Webb telescope, though it could be replaced it probably wouldn't get funded).

I agree with you: everyone else will be playing catch-up, probably for a decade. But what I mean is say I have a payload I want to launch. I go to spaceX and they say they can put my payload on their manifest for 2019 for $60 million. I g

SpaceX would still have to deal with scheduling: making enough upper stages and having limited launch/landing pads they share with NASA/ULA/ATK. So those with less cost-sensitive payloads (governments) would probably still p

by rrmm 10y ago
They wouldn't have a monopoly since there are plenty of other launch services out there (ULA,Russians,ESA,etc). The fact that SpaceX will probably be able to do it for much cheaper doesn't factor into it.

You can also have the program tell the user what's going to happen (if it can be computed beforehand), e.g. "This will affect 138 server(s)."

The NAD is just trying to get the most for their members using the law. We are mad because we can't have access to free stuff that seems socially beneficial. This is people and society trying to find a balance. Is this the right bal

I don't know how far I'd want to go down that path. Cochlear implants aren't risk-free. I'm also curious about the implant's ramifications if other interventions (e.g. stem cell treatment) become possible.

Apparently Berkeley doesn't owe us free lectures. It's definitely a crappy resolution to the issue though.

The lossy part of PSTN occurs at the front-end where only a 3KHz band of audio is passed through the network.

Scenario one stands out to me. There will be a lot of hardware between you and the other party in your call and trouble can happen at any of them. The connection quality you get will depend on the worst performing hardware in that chain.

I have also been moving towards Kicad. (Amusingly enough, I was also bitten by the Apple eMagic/Logic buyout). Unfortunately, the way technology moves on, the only way to really ensure this is to commit to it as an active process. Muc

In my state you just need to file simple articles of incorporation with the Sec. of State and then keep up an annual fee. (If there are multiple people involved, you probably want to get them looked over by a lawyer in case disputes arise)

Indeed, the name and their use in sci-fi settings trips people up into thinking they are some weird theoretical construct. Medical imaging is a place where positrons are used in everyday life. Specifically, PET imaging or positron emission

Agree, KSP is a great way to internalize how orbital mechanics work. After playing it a little while, everything clicks and things become natural, like the sort of physics one uses playing billiards or building block towers.

The weird thing is that fueling the vehicle was the worrying part not the landing.

Is this the first time the live video/split screen feed has followed stage 1 all the way down? I remember them releasing a time lapse after the fact, but I don't recall them showing it live.

Yeah, soon enough it will be gone, but radio is probably more robust in large scale emergency situations (insert catastrophe of your choice). Personally, a cellphone hasn't become a routine item for me. I don't really carry one a
