Yes. The last stuff I wrote that I couldn't compile today was in "Promal" or "Paradox". My C and C++ code from 1980 still builds and runs.
All of my web development is on Ruby on Rails. That environment has had a lot of development and I've had to port to new versions. So old code for RoR would not quite run out of the box, but it's close.
When I read this article this is what I saw. A traditionalist complaining that we don't teach kids arbitrary ancient skiils, like drawn up handwriting, or going to the library, finding a physical book, and looking up some factoid.
I know a lot of people over 40 who cannot use the computer. They are skilled, but never were taught how to learn new skills. This is what STEM education offers over what many see as a classical education.
It is not that classical education does not offer critical thinking, it is that we need to integrate critical thinking with the machinery that runs our civilization. A lawyer who is going to be successful cannot just have read the classics. A lawyer like that will probably be replaced by a machine in my lifetime.
When I was in school, parents were told that a pre-engineering program was not just for engineers. I was a holistic program that would give kids the background to succeed. We could write an essay, we could write fiction, we could write technical reports, we could program a computer, we could draw a schematic.
The only people who are going to value a pure humanities education over one that stresses science and math are those who are afraid where the world is going.
Popular computing languages do not in general have only one Open Source implementation, and do not get abandoned.
Cetaceans Able To Focus Sound For Echolocation
Well crustacians are able to focus sound for murder . Beat that, cetaceans!
Development with a proprietary language is ultimately harmful to your own interests, whether you make proprietary software for a profit or Free software.
The one thing every business needs is control. When you make it possible for another company to block your business, you lose control. Your options become limited. Solving business problems potentially becomes very costly, involving a complete rewrite.
The one thing that should be abundantly clear to everyone by now is that making your business dependent on Microsoft anything is ultimately a losing proposition. They have a long history of deprecating their own products after customers have built products upon them.
All Open Source licenses come with an implicit patent grant, it's an exhaustion doctrine in equitable law.
The problem is not patent holders who contribute to the code, you're protected from them. It's trolls who make no contribution and then sue.
Of course these same trolls sue regarding proprietary code as well.
Do kids still wear this T-Shirt in college?
Most MOOC have a big problem. They don't educate a different kind of student. They educate the same highly motivated student. The only benefit is that student may not be able to afford a traditional college, or be able to read at a level required for college. It is a real benefit, but the nirvana.
Codeschool does a good job leveraging the strengths of the computer and targeting learning to those who were raised playing video games. Learning for non-traditional students involves active learning, not watching a guy on video.
Wow, this is great to hear - I'd never heard of you guys before.
And looking at your site, I like what you're doing even more - direct 3d printed aerospikes? Pretty darn cool. What sort of 3d printing tech are you using? Have you looked into the new hybrid laser spraying / CNC system that's out there (I forget the manufacturer)? The use of high velocity dust as source material gives you almost limitless material flexibility and improved physical properties that you can't get out of plain laser sintering, and the combination with CNC yields fast total part turnaround times.
And you're working on turbopump alternatives? Geez, you're playing with all of my favorite things here....
What sort of launch are you all looking at - is this ground launched (and if so, do you have a near-equatorial site) or air launched? I'd love to see more details about your rockets, what sort of ISP figures you're getting so far, how you're manufacturing your tanks, and on and on. But I guess I'll have to wait just like everyone else
I wish you lots of success! And even if you don't make it, at the very least you'll have added a ton of practical research to the world
Note that it's technically possible to have something like this with a slow reactor; you could for example use steam as a moderator, which will transmit a reasonable proportion of near infrared through it (the hotter you can run your fuel particles, the better transmission you'll get). But not only will you lose some light, but just the simple act of neutron moderation is a very heat-intensive process, meaning big radiators if you want big power (not to mention that the moderator itself for such a slow reactor is also far heavier than the core). The whole point of my variant is to avoid the moderator and avoid the ship having to ever capture anything but incident heat lost due to generation, transmission, reflection, etc losses.
One possibility for a slow reactor, albeit only directly applicable to the rocket mode above, is to have your propellant be your moderator, absorbing both IR and moderating fast neutrons. The fact that it's heating then becomes irrelevant (actually an advantage), since you're dumping it out the nozzle for thrust. If one wanted mission flexibility in such a scenario you could have such a moderator-ejecting rocket mode used to get to orbit, and then switch to retaining the moderator once in orbit and cooling it instead in order to make use of the fission fragment operating mode.
But a fast reactor would obviously be highly preferable so you don't have to worry about a moderator at all.
Wait a minute, no, I entered it right into the calculator the first time around. Argh, this interface is confusing. Radiative equilibrium for Tunsten at its melting point 3300C according to the calculator is 92MW/m. A "cool" 1200C radiative temperature according to the calculator 2,6MW/m. According to the calculator, 10kW/m is about 380C.
The DBA probably gets paid a lot because the company is desperate for someone to come in and fix the database after the developers thought they could do the job themselves.
Sincerely, a DBA.
