I agree. I would rather use NTO or MON than HTP. There's a much longer history of successful rockets using it over decades. Well actually I would rather use LOX than either of those cryogenic or not.
That's not all. I didn't see any test firings of their engine at all. Not even a cold firing. They're building stuff, sure, but I didn't see anything actually working there.
There is like one rocket which used HTP (Black Knight) from the UK. Few people have experience handling it. In the USA perhaps you could get some Naval torpedo guys who know how to work with it. That's about it.
I think the biggest issues are lack of easy access to H2O2 at the required purity and know-how on how to use and design for it. Rather than other considerations.
I think they also underestimate the fact that having a cryogenic propellant actually simplifies some things on rocket engine design.
AFAIK they did get a simpler carbon composite LOX tank to work. But they never got the LH2 composite tank to work. LH2 is deeply cryogenic and the small molecule permeates things easily. Funny thing it an Al-Li LH2 tank would have been lighter than their composite tank design because of the required complex multi-lobed structure in the design. They could have used Al-Li tanks and they would have been globally lighter than their carbon composite designs.
Actually the major design issue with the X-33 was because of the aerospike. It was a lot heavier than expected and it changed the center of mass of the vehicle. It would require a major redesign that would involve dumping the existent prototype and starting over again.
The Arab League? A bunch of countries sucking at the Saudi's teat? Color me not surprised. Where do you think the ISIL troops and funding come from to begin with?
Mind you, if it's the Saudi's invading Bahrein or Yemen, then everything is peachy. But of course Iran is the aggressor.
Such a bland card. Twice the money of a GTX 1080 Ti for 10% more FLOPS. It does not even use HBM. The half precision and double precision performance is still nerfed. It's got like 1/4 the DP FLOPS of a 2013 GTX Titan. The card is only good for SP FLOPS. So it is useless for a power user which wants to do something other than gaming.
Your complaint also doesn't make a huge amount of sense. It's not like you're levelling the same complaint at Windows, which incidentally also has a whole slew of crap in it to deal with obsolete display tech that (like X) they keep around for compatibility with old programs that were written when palettes were a thing and beyond that, it's not exactly common to write a Windows program with direct GDI calls anyway. So if Linux is behind, what precisely IS it behind?
Notice I did not mention Windows as an example for how to do things.:-) Sure a lot of people use it, I use it too, but I avoid programming for Windows like the plague. The only way to do it, without tremendous pain, is to use something like C# to hide the ugliness of it all. Both Linux and Windows are way behind MacOS X. But even MacOS X is getting kinda dated. Remember all the jokes about how user interfaces in Linux were a mess and each toolkit had its own look and feel making the desktop look like a patchwork of applications? I wonder what those people would say if they used a Windows 10 desktop. Hah.
With modern programmable graphics hardware you can write pretty much any graphics interface you think of. In that respect it's kinda like old times where X11 had support for all those stipples, and arcs, and weird things like that because much of it was software. Much of the early Windows GDI was about accelerating the S3 operations (rectangle draw, line draw, BitBLT). Later they had the idea to merge the printer and display. That resulted in a minor mess as most cards couldn't accelerate the more advanced ops. In addition GDI+ is not a 100% match to what the dominant print format (PDF) we have today requires. I've seen proposals to make the low level just a bunch of pixel buffers you can write to. I don't know if that's the right approach to doing things though. The vector approach that MacOS X uses seems, to me a lot better, especially as screens keep increasing in resolution.
A lot of things about X are kinda inane. The font system is shit and was basically sidestepped with Xft. While the 2D graphics system is palette based. I know it supports true color but the way you use things is quite suboptimal. OpenGL supposedly fixes that (another extension). But in practice, because not everyone has GL on their system, quite often rendering is still done over the old interface. It does not have support for running application graphics code on a GPU at a low level either. It was never conceived in that way. Once you realize that you are using a bunch of extensions and the pretty much all the standard API is legacy baggage, that is when you should think of redoing things over. But for that to be done we actually need a lot of infrastructure we don't have today in Linux at a robust enough level. Like Vulkan and SPIR-V. With OpenCL and GLSL running over it.
It was kinda cumbersome to get used to Unity at first though.
I came from the absolute opposite (non-modal) school of using a desktop (for a long time I was an FVWM user w/ sloppy-focus, later I switched to Window Maker). So this extreme modal like click-to-focus desktop in Unity felt strange at first. But IMHO Unity is quite good at what it does. In like 2-3 days I got used to it and it doesn't bother me anymore. Unity was certainly a lot cleaner and less clunky than GNOME 3 was at the time.
Unity uses the opposite user design philosophy to what I prefer for a developer's desktop (i.e. sloppy-focus for work with multiple windows). But IMHO, given what Unity aims to do, it does things extremely well from a user interface perspective.
If there are things which need to be trashed in the Linux desktop, it would be the Xlib as the default API (something like Quartz would be a good replacement and is long overdue), ALSA, Pulseaudio, and systemd.
Xlib and ALSA are the biggest reasons for the Linux desktop lagging behind everything else. They're horrible APIs. ALSA in particular is overly complicated, device specific, and complete trash. Xlib was a good design when it came out, but now that we have true-color displays, and that remote graphics make less sense it doesn't work anymore. Because ALSA and Xlib are horrible APIs, we get tremendously bloated, buggy messes of intermediary APIs to hide their overall suckiness (e.g. Pulseaudio and Qt). Pulseaudio and Qt are probably good compromises but they're the wrong solution to the problem. The problem needs to be fixed at the core libraries, not by plastering wallpaper over the cracks. Then there's Qt and MOC. Fuck MOC.
Systemd is just absolutely horrible. A jack of all trades and master of none. A bloated pig, that even its own developers probably don't understand anymore, let alone the users. it goes against the UNIX philosophy of doing only one thing and getting it right. If we want the Linux desktop to win over its rivals Windows and MacOS X, we need to push our own vision of an OS for power users. That's after all what UNIX is all about. I don't necessarily mean programmers, it could also be artists and documentation specialists. i.e. if I was a translator wouldn't I want multiple windows open at the same time with dictionaries, the text I'm working on, a glossary, etc? If I was an artist, wouldn't I want to be able to launch renders and know their status in the background while I'm working on something? An OS that empowers people and makes them productive. A desktop for large screen displays where you can work with multiple documents visible at once. Not smartphones and the card deck metaphor. Not an OS that reduces everyone to the lowest common denominator. But an OS that allows everyone to work at their peak ability.
Another thing Linux could use would be its own runtime with architecture independent binaries and application packages. Even if it's a copy of Android's. I know it isn't good for high performance apps, but we need a runtime for shovelware that doesn't suck.
The thing is the wealth in the car sector is in those segments. It's the same reason why Porsche calls the shots at Volkswagen. Once the Model 3 is available they'll cover most of the segments that actually make a profit.
North America pays better than in Europe. But you should check the salaries for top notch software programmers in Beijing, China. Prepare to be amazed...
Not that I would want to live there though, considering all the air pollution not to say other factors.

You know the SpaceX Falcon 9 "Octaweb" engine layout in the base of the 1st stage? Look at the base of the first stage of the N1 rocket sometime.
No shit. Same thing happened to me. I returned it and got my money back.
The construction industry and the banking sector appreciate your patronage.
I see. You're one of those miserable people that just focuses on whatever does them money. Then just stick with Java and don't annoy us.
Quiche eater.
Then figure out for yourself if you like it or not. If you're going at this from a PHB perspective just stick with Java.

exFAT I bet.
I thought Android used the Apache v2 License which already has a patent license in. So what's up?

Acid injuries? I thought Toyota used NiMH.
PS: I think Jobs could have done it, but Tim Cook isn't SJ.
Apple doesn't have a clue about how to make a car. It would be like fearing Microsoft will enter the mobile segment.
No shit. It would be a great Xanatos Gambit if Tesla tried something like a merger with Ford or something stupid like that and managed to do it.
Porsche is owned by Volkswagen which, in turn, is owned by Porsche SE. It's owned by the Porsche family and Wolfgang Porsche is the chairman.
The thing is the wealth in the car sector is in those segments. It's the same reason why Porsche calls the shots at Volkswagen. Once the Model 3 is available they'll cover most of the segments that actually make a profit.
Android was acquired.
It doesn't quite cover the difference, but yeah having one month paid vacation and universal healthcare helps to soften the blow quite a lot.
North America pays better than in Europe. But you should check the salaries for top notch software programmers in Beijing, China. Prepare to be amazed...

The Manatees are rebounding! People Eating Tasty Animals approves!
At least it has air-con. Wal-Mart can't fry its customers.
