I've published the source code of my own products since about 1987. The difference between Symantec and me is that I give the source code to everyone, and I give them an incentive to read the code, because they can also redistribute and modify it, and put it to any use.
And of course a national entity that wants to enough, like the government of Russia, is going to get a look at the Symantec source code even if it means getting someone into a job there to do it. So, isn't Symantec just saying that their proprietary paradigm is a poor one from a security perspective?
I agree that they've been doing a good job in near-orbital space and I would have been a lot happier had they stuck to that. I would also like to see them turn profitable, as no matter how well they are doing now it doesn't matter in the long term if they can only do it with yearly Billion+ capital injections rather than be self-sustaining. They've now brought 17 boosters back, but haven't yet shown that they can turn one around at a net savings.
Mars is a diversion from what the company should be working on. And their schedule (10 years!!!) is so crazy that IMO it's lying to investors or prospective investors.
I propose a test for any new unconventional propulsion.
Bring it to ISS, and raise the orbit. Even a little bit, we can measure that orbit very precisely. Call me back after that works, please. Not interested until it does.
I fould find all of this to be a lot more credible if Musk was seriously interested in the moon rather than just posing it as a stepping-stone to Mars or a means of addressing current objections. If we can't have a viable colony on the moon, Mars is really unlikely. Even if we can, Mars is inconveniently far away.
You can't be a multiplanetary species if you can't have children on multiple planets. It is astonishing how little research there is on that little detail at present. We don't know that humans can birth healthy children on Mars.
And any kids you do have on Mars are probably not coming back to Earth and its 3X gravity.
Mars is hot air, yes. They were a great orbital rocket company. It would have done a tremendous lot for the world if they'd stayed an orbital rocket company. They might have even been able to finish the economic part of bringing 17 rockets back, which is flying them again at a net cost savings.
They haven't done that yet, and it will take several years, probably at least three, to achieve that.
SpaceX can't open space. They can only publish pretty videos of a spaceship they can't ever afford to build.
Did you see their plan for being able to pay for the spaceship? First, they will launch a network of about 8000 satellites. Now, Iridium just had about 120 and one of them still hit another intact satellite. But SpaceX is going to launch 8000 and then they'll corner the market on providing the internet using those 8000 satellites, and then they'll be able to afford to go to Mars.
"Aspirational" is a polite word for this. "Lies and fraud" is closer to reality.
Yes, SpaceX can bring them back, but they have not succeeded in re-flying them at a net cost savings, and to do so will take them several more years if it's even possible.
The point is that you can't sell the radio without FCC approval. This concerns me because I am producing an SDR radio that is supposed to be 100% Open Source, but in order to sell it as anything but test equipment, I need to have one little non-Open-Source part that keeps the receiver from being programmed to receive AMPS cellular.
Industrial and farming machines are dangerous, people have heart attacks and strokes, and people have lots of other reasons that they end up in a helicopter to the hospital. I'd assume that the hospital is being fed by a large portion of at least two states, and probably smaller hospitals.
Those of us who live on the coasts might discount St. Louis and the two Kansas Cities as fly-over country. However, both are relatively big cities. St. Louis has a large university, a regional medical complex that covers 7 or 8 square blocks, working mass transit, and a good deal of industry. Last month when I was there, helicopters never stopped flying in and out of the hospital heliport.
Kansas City is two cities straddling a river and state border: Kansas City Kansas, and Kansas City Missouri. It has more population than Atlanta or Miami.
The hyperloop has a lot of human issues people seem to underestimate. Current designs would be uncomfortable and claustrophobic, and safety of a big thing moving really fast in an evacuated tunnel is problematic. High speed rail, on the other hand, can go really fast without the problems. The assumption that a hyperloop would be less expensive than rail is unfounded and untested. And the hyperloop itself is little tested other than models on a short, linear track outside of SpaceX. The hyperloop may be real someday, but that time has not yet come.
The corpus callosum is not the only connection between the halves of the cerebral cortex. There are all of the lower brain structures. And most modern callosotomies are incomplete. So no surprise that a modern researcher would get different results than the past.
When I worked for HP, our PR company contact introduced his company to me, pointing out that one of their differentiating capabilities was that they did negative publicity as well as positive. In other words, they would place a negative story about an HP competitor if asked. I wasn't ever involved in asking them to do that and don't have proof that it happened, but they certainly offered the capability. The board was later involved in breaking the law with pretexting. I don't doubt the board or managers down to the section manager level could have made use of negative publicity.
The stock is at 341 from an all-time high of 383. This is not a tremendous sign of disapproval of the market. It's more like regular cyclical pricing changes.
When Prius was the dominant hybrid car, auto companies paid for lots of anti-Prius stories. Now, it's anti-Tesla stores.
I doubt I'd buy them at this price, but if I were holding I would not sell. It's not like the entrenched automakers will suddenly become agile, come out with better electrics than Tesla, or achieve Tesla's quality level.
Nickel-hydrogen batteries in satellites can last 40,000 cycles.
How has my Prius lasted for 10 years on the same battery pack? Because the software never discharges the battery below 20% or charges it above 80%.
Good charge management software is one thing. Also, the satellite can be designed to work in sunlight with an open or shorted battery, which is how AO-7 is still working after 43 years. AMSAT's experience in space has taught them a lot about battery failure.
You can build one, but you can't sell a VHF/UHF transceiver that is not type approved, because all receivers in VHF/UHF bands are considered to be scanners, and thus must be type approved. It's not in Part 97 but elsewhere in FCC regulations.
New amateur receivers are type-certified for avoidance of the old 800 MHz analog cellular frequencies, as required by the Electronic Communications and Privacy Act in 1986. So, you will see a notice about radios not being offered for sale until they are type-certified.
I would like someone to help work on repealing that provision of ECPA. Obviously everyone uses encryption now.
It looks like the FOX series of low-earth-orbit cubesats are using STM32 and GNU C. Here's a slide show. Because these don't traverse the van Allen belt, they don't have to be as rad-hard as higher-orbit satellites.
These are probably better than my explanation. A German space scientist, Karl Meinzer, designed this all in the 1970's and it's still being built into satellites.
I have seen people do this by hand, it really doesn't look so bad. The satellite is always going to start at the horizon at a predicted time, and then cross over you. So, you can always start at the lowest elevation that is clear, and just do azimuth with a compass (remember declination).

Being able to build an electric car is pretty darned far from building a mission to take people to Mars and bring them back successfully.

Don't buy Elon Musk's bullshit.
Actually, you always had a user-ID, you just could not see it. It was necessary for the database and software to work.
The problem of people impersonating me on Slashdot was so serious that it inspired this song.

Spend more time around adult Koalas. They aren't the cute things they're portrayed to be.
