In-Flight Reboot?
·
· Score: 2, Insightful
Yeah, 36 seconds a flight. Considering that most of the programming and everything is probably kept in solid state memory, a reboot maybe takes a second or two at most.
The language used for all of this is ADA, which is one devious language to program in. Everything requires exception handling, and every exception needs to be handled. The 2 million lines of code is surprising, not because it seems like a lot, but because it seems like so little.
I'm quite sure that every computerized portion of the aircraft has at least one redundant system too. The aircraft has already been through it's "X" stage. It's been officially given a fighter designation, and they do have a flight of them somewhere. The military isn't going to stick pilots in a rickety plane. If the craft didn't have redundant systems, and the flight suit went out for a couple seconds during a 9 G turn, the pilot would be out. Soon after, the plane would be gone.
The fact that they are still working on the stability is a cool thing. If I were piloting, I'd want my main system to be rock solid and never crash, but I'd also want all of my redundant systems to be rock solid and never class.
I've modded my case to include a window and a nice paint job. I think the next on the list is to just build a well-ventilated case from scratch.
The problem with mods is finding the time and motivation to actually follow through with them. In the case of painting, you also need to find space. Oh, you'll more than likely need a dremel.
The next mouse mod for me is the lego chick trapped in a cryogenic chamber. I don't remember where I saw that, but it was a really funkadoric mod. Now, before I start to get cold feet about actually doing the mod...
I think that is the point. The only way to get the data is to crack the case and read it off the plates. When they say "keep the government busy for weeks," it means that the actual bits on the HD don't make any sense until they are decoded.
We really need someone who is under 18 to sign the NDA and look at the code snips. Then said person could release it to the internet community for the masses to consume. SCO would be a burning wreck then, mostly because you can't prosecute a minor for breach of contract.
I *NEVER* buy anything sold by an anonymous phone (or door) solicitor. Rather than sue, these folks should embrace the change for the better of all mankind!
No! You buy everything you see on T.V. instead!
Honestly, though, why is there a difference between phone calls, door to door calls, and television ads? Why are we so lax on commercials? They are harassing, burdensome, and interfere with my ability to watch normal television. If I don't want commercials, I have to pay for a premium channel, and that usually costs a premium.
The Windows.Forms class is basically a wrapper for GTK/GTK+. GTK# may be the Linuxy way of doing things, but in order for complete "interoperability," Windows.Forms has to be implemented. With that done, any application that doesn't use the Platform/Invoke COM interop stuff can be compiled and run on Linux.
I doubt that Mono is on shaky ground. The code is 100% original, from scratch, there will be no code borrowed from MS for the final iteration. This "platform" that has the same functionality as.NET on Windows will then be protected by the very thing that protects Windows from Apple. The court case.
If you look at MS's original GUI, and how it has the same functionality as the Apple GUI, and how MS was allowed to have it... why should Mono be allowed to persist? It's the same concept, although a different approach. As long as there are no patents that are being used to develop Mono, then it should be a legal as NT or Win2K.:shrug: I have no problem with C# being implemented on the Linux platform. It will just attract the win32 developers that hate the excessive licensing or complete insecurity of the MS platforms.
My dad put it to me once in the best way about braces. He saw me programming with that style of putting the open brace after a line break. He said "So, you program with that shitty MS style, eh?" I didn't quite know why he disliked the open brace being alone on a line.
He said "All you have to do is grep for every line that has an open parens, and you'll get the entire control structure of the program." That's all the reason I ever needed. Putting the open brace on the same line as the conditional is easy to read, and has some good benefits too.
I feel shamed that I didn't attend that school, even though I was heavily recruited.
My only question is... how is a blind guy supposed to be able to point the scanner at the bar code on the product? Is there some sort of groove on the side of the can that has the barcode?
Even though I'm supposed to be the web developer, it is my primary role at this company, I find that I am called more and more for support. First, it starts as people calling me to report a flaw in my programming. That's all cool. Then I start getting calls about printers not working, computers crashing, the works.
I could sit here and avoid doing my actual job, but provide excellent support. I'm probably more knowledgable about computers than the actual support staff here. I just grin and politely inform them that their contact person is so&so.
When people are reporting bugs and issues, I know that I could give them a really hard time. A log of times, they are frustrated because they need to get work done, and usually within strict deadlines. I'm here to clear the path for them to do this work, the path having been cluttered by my negligence (well, only sometimes.) Yeah, my patience is tried at times, but I think that my boss's patience is tried even more than mine.
I know a dude that pays extra for AOL while it sits on top of DSL that is provided by SBC/Prodigy. His e-mail address is "@aol.com" but his headers looke like "Recieved from XXXXX@2.4.4.4.Prodclients.sbc.com" or something. I asked him why he didn't just dump AOL and pick up SBC/Prodigy or AT&T, and he said that he "liked AOL."
People don't see the trunk when they look at the trees. They see that trunk and the squirrels and the leaves, and they like it all in one big package. The true geeks took that trunk and built a house out of it when they had the oppurtunity.
My aunt is one of those. She recently bought a digital camera, and wouldn't use it until she had taken a class on digital photography at the community college.
She then asked me to install a CD-burner, and wouldn't burn a CD for the first couple of times without my breathing on the other end of the phone. I only sorta understand this mentality, since I'm more of a "lets play with it to figure it out, and if it breaks... then we get to see what it's made out of!" type person.
If I encode a song, or any data for that matter, using some sort of compression algorithm, do I own the copyright on that sequence of bits? It isn't a derivative work at the bit scale, in fact, I'm willing to bet that the data within an OGG or MP3 is vastly different from the data contained on a music CD.
If that is so, I would own a copyright on a certain sequence of bits. What if I wrote them down on paper? What if I just happened to write them in memory using assembler? What if I happened to write that memory buffer to a disk, and give a name like "blah.ogg?" I would be able to own the copyright, especially if I found a particular use for them anyway, right?
If the prez vetoes, he will be such an asshole. He already is, to an extant. I still think that we're better off with him than we would ever have been with Gore, but I digress. It's not like we had much of a choice anyways.
I already feel some amount of shame for voting for him, but I will completely shamed if he vetoes. I really would like this bill to pass. I really hope that the pres listens to the majority of the population in this one, considering he has to put his job on the line in a year and a half or so.
The key word there is "buy it." The patent is out there, with schematics and everything. It gaurantees a monopoly in the market for that particular product for a limited amount of time. That is, in the market. I can build my own dyson vacuum and use it legally, I just can't sell it as a product.
How will anyone be able to prove infringement if it's close source?
Didn't you know? SCO created and owns the Command Line. They also filed for a patent on it, therefore anyone that uses a derivative of csh or the Bourne shell is liable for litiguous action.
I would rather that we all just decide to run our own fiber, and have my next door neighbor Bob run control the 'hub. We'd have a grassroots municipal fiber-net, which we could do with as we please. We could also run the internet side-by-side with it.
All we'd have to do is assign interesting DNS domains like '.rebel' and '.bitch.' Google would have a place, of course, and it would be 'www.google.bitch' or something.
We could get rid of IPvAnything, and have home-brewed hardware that would would work with address schemes like "14|\./|13.37j0.0|/\.|H0"
I still don't believe that 35 trillion addresses will be enough. I remember a time when some stupid guy once said "640K should be all the memory anyone needs," or something like that.

Last time I checked, I had more than 20 MB of C++ libraries sitting on my machine. What's your point?
That's quite a flame-bait post.
