Interesting comment, most likely correct. I bet that some of those that feel outside of the so-called mainstream for whatever reason (keeping in mind that the "mainstream" is not exactly the panacea it is made out to be) have an axe to grind and seek out a way to find some kind of rebellion.
Outside of inheriting wealthy or royal genes, having a 'job' has traditionally defined social status. And the more money, the better. In the computer geek world, knowledge is more highly valued and I guess we'll see how this works out in the long run.
I remember it from the beginning of Supertramp's Fool's Overture. Gotta admit that the Iron Maiden lyrics made better sense for more obvious dramatic historical context, though.
The LOX issue, however, is not likely related to this - this is about preventing ice formation on the LOX lines (they didn't state which ones), not the tank itself.
In order to diagnose a piping problem, you start with a P&ID. Is this available?
Are the LOX lines vacuum insulated? Are they in proximity to other "stuff"?
Sometimes fresh cryogenic eyes can spot problems. I am by no means an expert, but I've routed a few LOX lines (inside and outside cold boxes) and understand the design philosophy.
QC has nothing to do with one-time pads. You could use the key material for OTPs, if you're deranged. More likely you'll use something like CBC-AES, CTR-AES, CBC-3DES for encryption, which are much faster (less key material, not limited by QC data rate), simpler, and safer (unless you have the resources of a major world government to oversee proper handling of the data and key material at every point from creation to destruction). At any rate, you'll still need integrity even with a OTP or your data is worthless. That means SHA1-HMAC, CBC-MAC-AES, etc.
After reading all that complexification, I'll just put some junk in random places within the information and then explain it in person to the trusted few that need to know. I'm talking about R&D work where parts are outsourced so that no one individual fabricator knows the whole picture.
If anyone can figure out what I intend, well, hats off to them, and let's see if they're fast enough to follow and implement. You can be sure that I'll be leaving a few, non-obvious red herrings for the semi-dedicated. Those who *really* know the field will already have a clue.
Oh, you were talking about DATA security, sorry.
Computer security is pretty much a joke, but at least it provides jobs.
I remember the days when these exploits were much more sinister in nature.
For example, while completing a paper drawing of a refinery unit, sometimes my 0.3mm plastic lead pencil (while drawing on mylar) would just disappear, leaving me with nothing to do. Other times, I'd arrive in the morning to find that someone had replaced my original drawing with 17 or 23 (can't be sure, really) copies of it. Then I had to figure out which one was the REAL original. Drawing on a copy is pointless, because the REAL original was elswhere and someone would sneak in a modified "original" the next day and the boss would claim that I didn't do anything the previous day.
Other times, I'd send some blueprints to the field only to find out later that they had been mysteriously translated into Polynesian for no apparent reason, and 3 Polynesian engineers had to be hired, trained and taught the safety rules for the construction site.
I could continue, but somehow I think I'm going to get replies that are promoting more software as the solution. It must be nice in that fantasy world.
That is correct, I think. At one point, software will be "good enough" (already, for millions of people, most software is "good enough").
After a dozen or so years of adding flashy gimmicks, convincing users to upgrade for no real reason (except maybe to lock-in existing users into the nextest, greatest vapour concept) the reality will settle in to most users.
In my field, computers are a great tool for manipulation of data, visualization and toys for management to play with while they wait for the real stuff to happen.
Once the construction teams start working on site, things often change. Until mobile robots are able to replace construction workers the fantasy world of computer-assisted design where everything is perfect in the model will remain as an artist's conception, and not a true, effective engineering document like we used to use to build things.
Unfortunately, it's making housing prices go through the roof (even compared to the rest of the valley), and it's pricing some of us young urban professionals out
It's too bad that the possibility of home ownership (i.e., real estate prices) for new buyers has fallen victim (IMO) to speculators and existing market collusion.
Ever-increasing prices only benefit the brokers' commissions - hmm, interesting - and shut new, local buyers out of the market. Even if you are able to afford a $250K mortgage, it's not like you have actually "gained" anything because the price inflation is so rapid.
Is the phrase, "keeping up with the Jonses" an original American concept?
Why do I keep hearing things like US$50/month (and up) for home DSL service and US$80/month for cable TV in the states?
In Canada, DSL can be had for CAN$35/month and "extended cable" (i.e., without pay TV, but with specialty channels like Space, Scream, Discovery, etc.) costs about the same.
Maybe it's the communistic Canadian CRTC system that makes relatively cheap communications possible.
Any trusted site that links to lots of pages is going to have a huge link management problem. Every day hundreds of domains that it links to may expire. You can snap those up and buy trust.
That's a good point, and it has happened that some of my relevant subject matter-related links have expired and then, uh, changed content. Given enough (I mean time, not money) resources it should be possible to validate links on a regular basis though.
Is there a study somewhere indicating where typical, 35-40 year-old marketing/advertising type professionals rank? If it's low, I might be convinced to beleive in IQ scores.
Enter the PCP theorem! You can use it to show that some problems can't even be approximately solved in a reasonable amount of time, and that's what the original poster was talking about.
Reality intrudes, annoyingly:
I can approximately estimate when I'll arrive at the office tomorrow, but I have no idea of when the system I am designing will be completed by the welders or if the ambient temperature will be suitable for welding, or if..
Oh, wait, you were talking about theoretical stuff.

You silly; they were obviously using macros (which were not shown because it is complimicated and boring).

When I worked for companies as an employee, asking for a week of my vacation time at a time was almost scandalous.
As an employee (after a certain amount of time) you are guaranteed 4% pay; i.e., two week's vacation as well as paid statuatory holidays.
Not to mention the various thingamabobs, whatsits, doohickeys and willnots.
Is space a solid, liquid or gas? All can flow.
Even glass flows.
Apparently, hydrogen is the only known gas that heats up when expanded.
No company of that size can be defeated quickly, unless from within (corruption).
Now I'm lost. How can any industry that employs people wearing bunny suits be "corrupt"?

Did we ever get to actually see the underside of Jolene's boobs? If so, then Star Trek has come a long way.
But this series has a fanbase (much bigger and with a higher average IQ than the buffy fanbase)
There have been studies done or are you just making fun of blondes and the stereotypical "teenage angst" angle?
You are apparently forgetting that rust is more easily applied onsite than it is to build-in at the shop.
Maybe you are thinking of weathering steel?

I'm confused; do you hear "religious messages" in your head or are those bastards ignoring the DNC list and masquerading as someone else again?

That's unAmerican, heathen.
Maybe they pulled a NASA and predicted metric British billions. That could cause expectations to become deflated.
Come to think of it, Sagan might have been wrong...

Rinse. Repeat.
They probably should put the word, "stop" in there somewhere. My scalp is soggy and my brain is waterlogged.

I don't get it.
I've got points, and nobody seems to be replying to this. Why is there so few replies?
I may have to go waste them over in the science place where I pretend to know stuff.
