HackRF is designed to be test equipment rather than a legal radio transceiver. It doesn't meet the FCC specifications for spectral purity, especially when amplified. You could probably make filters to help it produce a legal output.
Whitebox is meant to meet FCC specifications for spurious signals that are required when amplification of 25 watts or higher is used. Amplifiers also contribute spurious signals and will usually incorporate their own filters.
HackRF is something that sticks on your laptop via USB. Whitebox is meant to be a stand-alone system or one that is controlled from your Smartphone via a WiFi or Bluetooth link.
Whitebox is optimized for battery power. Using a FLASH-based gate-array rather than the conventional SRAM one makes a big difference.
Oh sure. And I could solder with Mercury, and that has a really low melting point:-). I imagine the application for a solder with a 160F melting point is very specialized. I don't ever want to specify a transportation temperature limit for consumer electronics of 160F, a freight container can exceed that.
Drilling holes in a multi-layer board is liable to nail a trace you can't see. If you are lucky you can shine a really bright light through it and see all of the traces. If you can't, don't try drilling.
Guys fron San Quentin once attempted an escape with a makeshift canoe painted with the legend "Rub a Dub Dub, Marin Yacht Club!". It sunk and they were re-imprisoned.
If we look at jet aircraft, wear depends on the airframe and the engines, and the airframe seems to be the number of pressurize/depressurize cycles as well as the running hours. Engines get swapped out routinely but when the airframe has enough stress it's time to retire the aircraft lest it suffer catastrophic failure. Rockets are different in scale (much greater stresses) but we can expect the failure points due to age to be those two, with the addition of one main rocket-specific failure point: cryogenic tanks.
How long each will be reliable can be established using ground-based environmental testing. Nobody has the numbers for Falcon 9R yet.
Weight vs. reusable life will become a design decision in rocket design.
You mean it drops off too high and downrange to boost back to the launch point and too low to achieve most of one orbit before boosting back to the launch point. Right?
Like others I found the headline confusing. I read it as "Researchers are predicting the use of Wikipedia as a vector for the spread of disease". This may mean that:
Disinformation and ignorance are diseases.
Memes and computer viruses are diseases.
Wilipedia contains information that leads to depression.
Instructions on Wikipedia lead to substance abuse.
This is getting entertaining, fill in your own reason here.
One who makes great sacrifices or suffers much in order to further a belief, cause, or principle.
I am sure that fits. While SpaceShip II is mainly intended for a non-exploration purpose, the program has resulted in some significant advances in rocketry and White Knight II has significant non-tourism use. These pilots have been involved in other space efforts, I remember the one who was injured from the Rotary Rocket test flights. There are lots of safer ways for these folks to make as much money as a test pilot is paid. They do what they do to advance our progress in aeronautics and space.
Go away, troll. They certainly died while pursuing something intensely important that they were willing to risk their lives for. The fact that you weren't around to pull the trigger makes them no less martyrs.
I'm really not interested in hearing from you any longer. It's very clear that we'll never agree on anything, and the fact is I don't consider you someone whose opinion I value or who is worthy of any of my time.
We knew what was going on when you ran your anti-IBM campaign, sometimes even positioning yourself as arguing on behalf of our community. It was a way to lend credence to IBM and MS arguments during the SCO issue. To state otherwise is deceptive, perhaps even self-deceptive.
Florian, you would not be devoting all of this text to explaining yourself if you didn't feel the need to paint your actions in a positive light. That comes from guilt, whether you admit it to yourself or not.
Go write your app, and if you actually get to make any money with it you can give thanks, because it will happen despite what you worked for previously. Keep a low profile otherwise because your credibility is well and truly blown and you can only make things worse. And maybe someday you can really move past this part of your life. But I am not holding out much hope.
The fact is, you took a leadership position, and later turned your coat for reasons that perhaps made sense to you. But they don't really make sense to anyone else. So, yes, everyone who supported you then is going to feel burned.
You also made yourself a paid voice that was often hostile to Free Software, all the way back to the SCO issue. Anyone could have told you that was bound to be a losing side and you would be forever tarred with their brush.
So nobody is going to believe you had any reason but cash, whatever rationalization you cook up after the fact. So, the bottom line is that you joined a list of people who we're never going to be able to trust or put the slightest amount of credibility in.
And ultimately it was for nothing. I've consistently tried to take the high road and it's led to a pretty good income, I would hazard a guess better than yours, not just being able to feel good about myself.
It's sort of a chicken-and-egg issue. Debian doesn't get the help because Debian doesn't make itself worthy of getting the help. There have previously been paid developers working on Debian, they simply weren't paid by Debian.
I am beginning to be wary of systemd, but no. I am talking about anal-retentive policy wonks who believe they only make the distribution for themselves and have (perhaps without intending to) systematically marginalized Debiian and made the project a whore to Ubuntu.
There is a certain contingent in Debian that is not good for the project, IMO. I would like to see which side of a fork they are on, and pick tthe other.
Let's make a bet then. You pay me $1 if there is no credible commercially utilized cold fusion by 2024. I'll pay you $10,000 if there is. And please don't bother me until then.
Let me preface this with the fact that I'm an intellectual property specialist. I bill $450/hour, and still have lots of time to work on my startup without having to take venture capital.
I thought about some educational answers for your questions, but the insult at the start of your comment rubs me wrong and I decided I don't owe you anything. So, I'll save them.
The first symptom of a new but incomplete understanding of patents is gold fever. That is when you have an idea that what you are holding is extremely valuable and that you must protect it from others at all costs. People tend to get irrational about it.
So here is some reality: The fact that you have even published your video (which is "use in commerce" under patent law) invalidates future patents that you might file on that same art. Then there is the prior art (including art you are not aware of), and the recent court finding in Alice v. CLS Bank that invalidates most process and method patents which describe software. These all work against the potential that your thesis is going to make you rich through patent licensing.
You can get a patent awarded, perhaps, that you can use to hoodwink an investor, but forcing an automotive company to pay you? Much less likely and it will cost $10 Million in attorney fees to get there.
Probably your school wants 51% of the revenue and your grant funding sources (and those of your college department) may have their own policies on patents.
Yes, this is definitely a "WTF?" moment in the history of Slashdot. I suggest that you all just move on to the next story and refuse to feed the troll by asking him questions.

Eutetic solder (the old non-RoHS stuff with lead in it) melts at 361 F, everything else in common use melts at a higher temperature.

Anyway, I have better uses of my time than to waste another minute with you.

That should be "SCO and MS arguments".

So, I see this as rationalization.

This is actually two bets, isn't it? One is that I live to be 93. Not terribly likely.
OK, you're on. Not that $10,000 is likely to be worth as much in 2050.
Let's make a bet then. You pay me $1 if there is no credible commercially utilized cold fusion by 2024. I'll pay you $10,000 if there is. And please don't bother me until then.
