My MythTV box is accessible via SSH. Usually that's the best way to work on it, since it's pretty clumsy to do sysadmin tasks using a TV and a wireless keyboard on my lap. Sometimes though, like the drive tray problem and the BIOS settings issue, you just need to physically poke around the box.
The main thing is that I just wouldn't have enough spare time to fix a bunch of similar problems on other peoples' machines, local or remote.
I run MythTV with a journaling filesystem. What you find out is that Murphy's law has no exceptions.
For example, this summer I found out that my BIOS had an optional setting to automatically cut power if it thought the MB temperature was too high. The machine had been crunching on shows for months, but once the warm season arrived, it would mysteriously power down with no warning during long transcoding jobs. It took me a little while to figure out what was going on and turn off that option (the MB really wasn't getting all that hot; the threshold was just set way too low).
I've had video card driver I/O errors lock up the machine more than once.
Once an error at the Zap2it server caused the entire program guide database to empty out, so recording stopped until I reloaded it.
The latest screwup was somebody left the CD tray slightly open and then closed the front access door so the tray was stuck between open and closed. The kernel started logging millions of messages about not being able to access the CD drive. After a couple of days, it filled up the OS partition and MythTV stopped working.
MythTV has a lot of compelling features that make it worth it for me to maintain it, but I would never consider taking on the hassle of doing it for someone else. People tend to think that the shows they record are a high priority, so of course any problems have to be fixed NOW. It's bad enough answering to members of my own household when the thing starts messing up, much less handling the crisis for someone else on a phone help line.
Expect to be hanged for treason shortly afterwards.
Not quite. Judging from actual US civil wars, he should instead expect to land a cushy post as a university president or to retire then travel and write some books.
They've had unmanned Progress supply ships for decades. They're derived from the Soyuz manned vehicles.
It's really not that much of a stretch since the Soviet philosophy was always focused on control of the mission from the ground and automatic systems on the spacecraft, not from the cosmonauts. Just leave out the passengers and pack in more cargo, and you get an unmanned craft.
I was always under the impression that it was a bad idea for a business to split their products like that....
Check out the soft drink aisle at your grocery store. Both Pepsi and Coke have subdivided their colas into countless combinations and permutations from { diet caffeine-free cherry vanilla with-lemon "One" etc. }. All of these variations consume so much shelf space that there is little if any room left for other competitors outside the Big 2.
if you survived the hurricane and are a Mac, Linux or Firefox user you cannot file a claim online." That is blatantly incorrect, as you pointed out from the article.
If you're running a copy of Windows in a VM on Linux or a Mac, you're no longer just a Mac or Linux user. You're a Windows user.
And you will have shell out ~$80 to get a valid copy of Windows.
The statement isn't "blatantly incorrect". It's only incorrect under your pedantically literal interpretation. Of course any Turing-complete system can be made to emulate any other such system. That's not the point.
But lets wait a few weeks when the odds of winning are still 20M:1 for a $1 ticket. But the jackpot is now $50M. Consequently for a $1 bet at 20M:1 odds you get a 50M:1 payout. Excellent result, 2.5:1 payout over an even money wager.
Sure, the *chance* of winning is still infinitisemal, but the possible result is better than the odds so it is a statistical winner.
However, the odds of getting killed while driving to the store to pick up your lotto tickets are also typically around 20M:1.
It doesn't make sense to directly compare gasoline and plastic pellets on a volume basis to evaluate efficiency. The MPG number is only useful to show that the size of the fuel tank is in the same ballpark as those current cars, making it more feasible than bulky storage methods such as compressed gaseous hydrogen.
To evaluate efficiency, you need to measure the miles driven per unit of energy put into the hydrogen production facility.
I never really bought that "stockpile stewardship" angle. Wouldn't it be cheaper and easier just to get out the original blueprints, dismantle the old nukes and build fresh ones to the original specs? After all, one of the primary attractions of nuclear weapons in the first place was that they were so cheap to manufacture relative to their impact.
IMO, what they really want to do is create entirely new designs, and goofing around with tiny thermonuclear blasts helps them to do that.
One thing I noticed when using PostgreSQL in my databases class was that someone mentioned that MySQL is the only dbms that actually lets you exit the application when you type "exit". I believe in Postgres, you have to type "\q".
For both I just use Alt+Ctl+Escape and then click. But I only do it that way because I think that goth scull-and-crossbones cursor is so totally cool.
NO ONE knew the scope of this disaster until it was too late.
*I* knew what the scope of the disaster was going to be. About 5 years ago, Scientific American ran an article where the authors spelled out exactly what was going to happen if a strong hurricane hit New Orleans. The events have played out just as they predicted.
I don't see how anybody can be surprised at the outcome; this has been common knowledge for years.
It is the State governments and Congress that are supposed to act.
Congress did act, years ago. It directed the president to create agencies like FEMA. Now it's the president's responsibility as executive director of these agencies to make sure they effectively do the job that congress envisioned for these circumstances.
Since CO2 is heavier than the other components of air (1.98 g/L for CO2 vs 1.2g/L for air), the proportion by mass is even greater than the proportion by volume.
First of all, the current atmospheric CO2 proportion is actually 360ppm, or 0.036%.
I don't have time to go through a bunch of math here, but predictions are that the CO2 proportion will double relative to the pre-industrial level sometime in this century. (ref)
The fraction may seem negligible since you can't see it, but if you could see in infrared you might have a different perspective. For example, if you release a visibly opaque material such as dark smoke into the air, it can take less than 360ppm to significantly alter the visibility in the area. Now think about what would happen if the entire globe were covered with that smoke and you doubled the amount; that's what's now happening in the infrared band.
Of course, breathing the equilibrium atmosphere that existed before plants did would most likely kill you within seconds. It would be best to stick to a "long term" more in line with human timeframes.
..and that carbon dioxide comes primarily from where? Fires?
Yes, most CO2 emitted by human activities comes from burning fuels. However, I assume you mean forest fires. Those do not affect net CO2 levels over the long term because the carbon in forests had been pulled out of the air within the last few decades. That's not the case for fossil fuels.
Volcanoes?
Despite the popular urban legend that claims otherwise, volcanoes account for about 1% as much CO2 as human activities. Look it up.
of Animals breathing? Decaying animals and plants?
All of the carbon from those sources has been pulled from the air via photosynthesis in the past few years, so no net increase in CO2.
Does factory-created CO2 have a different composition that that made from fires?
Not a different composition from forest fires, but a different source of carbon as explained above.
Hey, guess what, that means they aren't burning coal or wood fires.
Far more coal is being burned per capita to generate electricity than was burned prior to the industrial revolution. As explained above, burning wood has no net effect on CO2 levels beyond the short term.
All carbon released from burning or decaying plant material will generally be recaptured by the next plant that grows to replace the previous one. There is no corresponding mechanism to recapture excess carbon released from fossil fuels. (Other than the process that got the fossil fuels there in the first place: gradual deposit of dead organisms into sedimentary rocks. That's a painfully slow process that is totally overwhelmed by our current rate of release.)
In summary, you really have no clue about how the carbon cycle works.
Slashdot Mirror
Yeah, like testimony from hardened criminals who have made a deal to back the prosecution's case in exchange for leniency.
Hard to believe, but true:
Windows XP: Oct 2001
Debian Woody: July 2002
Debian Sarge: June 2005
Windows Vista: ?? 2006?
That's true. And I put up with the hassle of using MythTV for the exact same reason that I don't use taxis for daily transportation.

I assume that even the crappiest flash drive trounces any magnetic disk drive on random seek time though.

... they decided to coat these pellets with a mixture of iron oxide and aluminum powder.
IMO, what they really want to do is create entirely new designs, and goofing around with tiny thermonuclear blasts helps them to do that.
Another advantage of the dual laser approach is that with one facility they can vaporize both legacy CDs/DVDs and the new high-density DVDs.

Opening a box that you own is not "participating" in a program.

- Non-compete employment clauses aren't valid in California.
- You can't sign yourself into slavery.
- Homeowner's association contract clauses that prohibit small satellite dish antennas are all invalid.
- Attempts to put an EULA on a paper book are null and void.
- There are very specific rules on how the interest and payments section on a loan are to be worded and formatted.
The list goes on and on. The real world just isn't as simple as you'd like it to be.
