Hmmm. Electricity. That's pretty high up on the "tech I can't give up" list. Fire trumps that though. Clean water... That's important. I've gotten by with just water purifier tablets but it would suck to have to live that way all the time. That'll do for the start of a list.
Building an Orion could very well bankrupt the nation that attempts it. It would be obscenely expensive; and, while it is the best our current technology could produce, it would be a hideously inefficient way to go about travelling between stars.
first of all, any high energy protons that come into the region around Earth are deflected by our magnetosphere. At worse, nothing happens. At best, you get pretty lights in the northern sky. Second, the particles aren't necessarily travelling at relativistic speeds, you are (when travelling at velocities approaching c). From your perspective, you're in a sea of relativistic protons even if they're standing still.
So close... and yet still a freeking impossible distance away.
Oh.. it's just 11 light years away. That's a small number, right? As much as I'd like to be able to say we have a "warp drive" or "jump drive" or something like that... at the moment 11 light years might as well be 11 million light years. it makes no difference to our ability to get there.
1. we don't have the technology to achieve that. 2. without some as yet to be thought of technology, the relativistic relative motion of the incident protons, even at 1 per cubic meter or so, would interact with the vehicle structure and create showers of particles, killing the crew.
What we need is a brand of coffee which contains an additive to help flush adenosine. Then we can get more productivity from our slav... *cough* excuse me, umm, happy employees.
Great. First you blow up Pluto, just to prove a point... then pieces of it come raining inward toward our planet. Next thing we know, we're going the way of the dinosaurs because you had to show off.
Her experience is actually not at all uncommon. Many astronauts report being uncomfortable for extended periods because of the shift in fluids messing with the body. Nausea is not uncommon because the middle ear ends up filled with fluid and there's no "down" for the vestibular system to reference. People in extended missions find they suffer from discomfort of muscles and joints. They experience vision changes and bone loss. The human body is just not adapted to zero G. Some never adapt; but, astronauts being a group of over-achievers by definition, the hide the symptoms and don't report them.
No one's going to actually go in and look at the reactor (or what's left of it) for a long time. What it does tell us is that most of the fuel is in the bottom of the containment vessel, and not hanging in the reactor pressure vessel. While TEPCO how they will use that information today it will affect their decision making process as they move forward.
Sorry. coding 8-bit, 32-bit and 64-bit embedded, as well as desktop apps. You missed the point. parent said
go out and buy another gig or two of ram for a few bucks.
seriously...its hard enough to find professionals to build software without getting bogged down with mallocs and leaks for god's sake.
when java first hit in the 90's, prettty much the #1 feature was its automated garbage collection...why now are we debating this now?
The reason I'm arguing it's important is that there are still a lot of applications out there where dropping in another gigabyte of RAM isn't an option. Embedded doesn't always have gigabytes of memory; sometimes your cost constraints put you in a 25 cent processor with kilobytes of memory. I'm coding 8-bit processors because I write code for embedded application which are cost sensitive. I'll use a 32-bit processor if the design specs show it's called for.
I just went on a rant at work because one of our programmers decided, at some point in the past, to write blocks of code in inline hexadecimal. With little to no comments. It had a bug... five bugs actually. I spent two days in the code, finding and fixing problems which should have taken at most a couple of hours, all because someone decided to be a "Real Programmer", aka elite ass. I don't care what the esteemed Mr. Raymond and Mr. Nather (the author of the article in catb.org) believe; we created higher level languages, like C, to make it easier to write and maintain code. I can write code directly using machine instructions too; but, I have too much work to do. As the parent said, don't be like Mel, we all have real work that we have to get done and someone will hate you later.
clearly written by someone who doesn't do any embedded programming on 8 bit processors. Your world is full of 8 bit processors. They outnumber the 32 bit and 64 bit processors by an order of magnitude.
Of course they're saying a vaccine is coming. You don't think they're trying to keep a general panic from occurring? Step 1, tell everyone it can't happen here. Check. Step 2, tell everyone it can only be passed via contaminated body fluids. Check. Step 3, tell everyone that a vaccine is imminent. Check. Step 4,... you don't want me to tell you about step 4.
Based on your commend, I suspect someone wired out your building in 230V 3 phase, since it's "close enough" to get away with in place of 120V/240V split phase; and, lets them put in more efficient 3 phase pumps and air conditioning systems. Some residential buildings and residential neighborhoods are wired out in 3 phase but the private residences only uses 2 of the 3 phases, except for the A/C system. Usually that's done in 208V 3 phase; but, it's conceivable someone could have put in 230V transformers.
it used to be 110/220V and 115/230V. Over time the voltage standard has changed. it's been 120/240V for decades now. Some very old equipment has labels for 110/220V and you'll see that referenced in newer documents where someone either doesn't know the standard or is old enough to remember when it really was 110/220V. 208V/230V/460V/480V are standard 3 phase voltages most people might interact with in the U.S. I've also seen 360V. I tend to not interact with the higher voltages like 4160.
OMB reviews, independent budget reviews and internal NASA reviews all say that at the current funding rate, the system will not be ready for such a mission for a decade beyond 2025.

It would be damned inconvenient to not have A/C; but, I grew up without it. I know I could get by with no A/C or forced air heating.

The sun is made of burning coal.
Anyone else remember when 10MB was a decent size disk and 30MB was huge? Man I'm getting old...

My version of Hell... would be cold. I'd expect ice and snow.

You do realize that, in this case, the practical skills test would involve launching the missiles that bring about Armageddon.

130V bulbs are for applications where the source is 230V 3 phase.
I've seen one too many scientifically illiterate alarmists who only want to protest for protest sake. "Let's go party at the Greenpeace protest"
If they don't like people burning coal for power, perhaps they should promote an alternative.... like nuclear.
North America is 120 / 240V split phase. 240V is common for all large loads in homes and small businesses.
