Why does the successful launch of one spacecraft prove that it's safe to launch manned spacecraft again? One successful launch doesn't prove anything.
Sure it can... The failure mode of Progress M-12M was a fuel duct was blocked so the computer felt like shutting down early which dumped the thing back in the atmosphere.
Its no great stretch of the imagination that a change in the software makes it not shut down early if flow rate drops a bit... If its going to be a total loss anyway, may as well keep burning.
Also no great stretch of the imagination to graph the pressure and flow rate thru the duct during the launch and see that the slightly modified design no longer decreases over time. And/or enhanced manufacturing Q+A now makes manufacturing mistake less likely.
Finally no great stretch of the imagination to stick three sensors in the duct and change the code to "2 outta 3" instead of trusting just 1 sensor.
(I have no inside sources, non of this is based on non-public sources)
It might be hard to believe, but even the Russians can do telemetry. Aerospace engineering can sometimes operate beyond the binary "did it blow up, T/F?" stage, even in a foreign land.
I'm having trouble peering thru the journalist filter and not finding any other primary sources.
To a first approximation, the point seems to be that what we used to be able to do with bi-layer two layer graphene, we can now do with tri-layer three layer graphene. Um, OK, thats nice but not "new".
So, aside from purely theoretical "thats interesting, just for the sake of physics", what is the point? More durable, better electrical properties, easier to make (thats hard to believe), stronger, easier to customize and control the above, or what? Someone with access to Nature-Physics to read the actual papers could probably respond?
The article is really poor because it tapdances around the important story which is what I list above.

Post high school TRAINING gets you something interesting to do and think about only 40 hours per week while at work. The rest of the time you're on your own.
Post high school EDUCATION gets you something interesting to do and think about for the other 128 hours per week.
Never forget that college etc is aspirational for the middle classes. For the upper classes it was always from the very start for the elite to give their kids something to think about and civilize/socialize their kids when they're not grubbing for money, because they're rich and power enough to not have to grub for money very much. The middle class aspired to attend to emulate their heros, kind of quisling-like, and turned college into an exercise in being a better money grubber, because they HAVE to money grub to survive. Which pushes the upper classes into more exotic ivy league type facilities just to get away from the grubbing, etc.
any more than one can hire personnel on the basis of what car they drive
A specific model or year or manufacturer HQ located in a certain country, no.
"reliable transportation", yes.
I went to the worlds crappiest job interview 20 years ago where they were paying mileage, but I'd need to buy a 4x4 to drive out to remote telecom sites with a couple dozen cubic feet of test equipment, I'd be on my own in possibly hazardous weather conditions so it needed to be pretty reliable.
I still see "reliable transportation" in some ads, mostly lower level stuff where you might expect the applicant to be too poor to own a car.
As a retired academic, I really don't see why tuitions have skyrocketed.
I'm guessing not economics? Supply and Demand.
The supply of attendance slots is vaguely fixed. It is true that 1000 person calculus lectures exist, but there is still a fundamental limit to how many you can pack in, even online.
The demand for attendance is we moved almost all our blue collar work to China or imported illegals.... Huge intense social pressure to "go to college", weirdly enough with no pressure to "graduate from college".
OK, so you graduate at 22. You pay off your loans in 25 years or at age 47. That gives you 33 years to save for retirement; how is that not enough time?
Soon, the medical-industrial complex will start fighting the educational-industrial complex for the production of their slaves. That money was all supposed to go to the medical insurance companies, not the student loan companies....
150% of poverty level isn't a lot of money, you can't live high on the hog with that kind of income, not even single.
First of all the poverty guidelines are indexed by family size.
Second, my wife and I work in tech and I'm making about 300% but my wife is only making about 150%, glass ceiling, shes a woman which means she will be underpaid for the same work, I've been lucky, we both trade semi-flexible schedules and high job stability and short commute and truly excellent living conditions/standard of living/environment for low pay, etc. Combined we're pushing 450% of the guideline and life's great, BUT if I become unemployed, thats it. Due to ageism and inflation and economic decline, I'll likely never make this much money again, and I'm not old. Adjusting for inflation I made quite a bit more money in the 90s...
If my wife popped out 6 more kids and stayed home to raise them (because the cost of daycare would dramatically exceed her gross salary) then we'd be in the 150% poverty range, despite being in the upper 10% of income for our area, well educated, extremely high paying (for this area) job, etc.
Why buy a support contract from an open source company if you can hire equal or better skilled consultants, or have an arrangement with a consulting service to always have a local guy on call? Aren't you better off with a local onsite guy who already knows you, your business, and your configuration? Thats kind of how it works in the Debian world... there's thousands of locals willing to provide support... for a price.
If, for the sake of example, you needed a Bind server running on Debian, why not hire on a contractual consulting basis a genuine Bind dev and/or one of the Debian Bind packagers?
You don't need support for "how to run the ls command", hopefully, anyway.
You're dead man walking already if you're tied to one specific distro and only that distro.
You carefully avoided describing why you selected red hat / centos.
If all you need is a generic "Bind" install or a generic "Apache" install, why deeply tie yourself to one distro? A sysadmin that only knows and can only learn one distro is about as useful as a dev that only knows one language or a salesguy who only knows one product and pitch. If thats all you got, you need hand holding and lots of space in the budget for the inevitable brain fart monetary losses.
Scenario: Horrific bug appears in red hat / centos / debian / ubuntu / whatever. Not in the other distribution red hat / centos / debian / ubuntu / whatever. You should be able to roll your app out on a new install of the safe distro in a couple minutes. Not hard if its all done in GIT and puppet and possibly running on a virtualized server.
You've gotta be kidding me. Nobody does stuff like that.
You pull the git logs on the config to see what changed either on that machine or the git config of the puppet server to see what happened. Roll back the changes and restart. You're doing this on a maintenance notification using your standard change procedure so you could work off that instead of poking around randomly in git.
Or, you just got owned and thats why binaries are weirdly crashing, an incompetent script kiddie.. Why your IDS didn't detect it is a mystery to be solved later. Disconnect from public network, reinstall a vanilla system, and let Puppet and GIT configure it to your needs, should take less than a half hour on bare metal, literally 5 minutes on any virtualization system.
I don't care whether it's 1993 or 2011, the fact is if something goes wrong, you need someone who can investigate, find root cause and recommend a fix.
That might be a support contract, might not. Review their hiring ads and compare them to your own internal talent. If they are wizards like the Cisco folks, then you rely on them and buy a contract from them. If its like HP or Dell and all you can expect is a script reader in India telling you to wipe and reinstall windows, don't waste your time.
That's when you need the support.
Some places will take money for a contract, and not provide the kind of support you believe exists in all areas of IT. No opinion here on RHAT
I'm sure this will be marketed as wholesome as apple pie "think of the children" holier than thou for christmas, but can it be repurposed for Valentines day to only allow the purchase of triple X videos or triple X toys? This could be kind of fun.

The other issue is that computers make processes too hard to change, which is how you end up with your "real" corporate standard database being Excel and relational SQL table merges being performed by an intern looking up values and typing them into MS-word. Been there seen it too many times...
Techs have to self educate themselves, unless they want to spend 4 years in university every 2 years of work. And if they can self educate, they don't need the training at uni...
Unless the business plan is to use em up, burn em out, send in another replaceable cog every two years...
With Halloween around the corner, parents now have another tool to...ensure their children stay away from... strangers’ homes
For real? In NY kids only trick or treat at family and friend-of-families houses? That must be weird. Everywhere I have ever lived, kids visit every house that has a light on, like a candy assembly line or something.
Locally we worked around the whole offender thing by passing one law that forbids offenders from living within Z thousand feet of an elementary school, another law requiring elementary schools in the city limits to be within 2 * Z thousand feet of each other, and finally only permitting new housing developments where the most distant home is less than Z thousand feet of the local elementary school. There are weird corner cases of grandfathered in homes in the old parts of the city and bordering industrial areas where the offenders all live. I have checked the maps and its certainly a growth industry, the offender rate must exceed at least 0.1% of the population. They are forming dense little colonies of perversion within those restricted zones.
I frankly worry a heck of a lot more about my neighbor with eight DUIs running my kids over, or the biker gang down the street getting in a shoot out (note, move in "nearby" a biker gang, because they're smart enough not to soil where they sleep, and other criminals are scared of them, so its actually a very pleasant crime free neighborhood...
How do the big anti-virus / security companies coordinate their work so as not to offend their local government?
Or, as the conspiracy theorists have long claimed, are the virus writers and anti-virus writers merely different departments of the same company, which makes coordination inside at least one company pretty easy?
I would imagine anti-virus / security companies based in the US and Israel are probably not getting "attaboys" from their government for figuring out the latest Duqu thing.
Preliminary data released from the SMU study in October 2010 revealed the existence of a geothermal resource under the state of West Virginia equivalent to the state’s existing (primarily coal-based) power supply.
I have been using Centralia's zip code 17927 for years for places that don't deserve my real address. Back when Radio Shack used to collect demographic information every time someone bought a battery, that sort of thing.

Because the lender doesn't pay interest on the money they borrow in order to lend to the student.
Check the federal funds rate, and get back to us on that loss. Its not 1982 anymore.
This is on the scale of arguing about how we round fractions of a penny, up or down.

Its a whole different ballgame if the boss is willing to hire someone who happens to be a dev for the OS.
That is roughly the position I operate in since 1997, but in a Debian world.
they'll struggle to maintain Linux without someone like Redhat backing them up.
I have to call that out. It has not been 1993 in almost 20 years.
You sure the facts are correct? I am pretty sure Oracle bought Sun, not Apple.
treating ARM boards like contemporary desktops just isn't going to work
Do I have permission to treat it as a 2002 desktop, which for 99% of the population is exactly the same as a 2012 desktop?
