If we also had a
"Last backed up time/scanned time"
that virus scanners and backup software could use instead.
Then all virus writer would be sure to adjust the "last access time" and "last modified time" of files they infect to be before the "last scanned time."
Seriously, virus scanners should never believe file attributes, and serious backup software should do hash checks to determine whether a file has changed.
Ahh, I see the difference. If he were a Republican he would have let you fill out the registration form and then would have shredded it after you left. Or he would have just gotten the Secretary of State to declare it invalid because it was printed on the wrong kind of papers.
If that didn't work he would just get you removed from the voter roles during the annual purge because you put "Apt #304" on your registration, but your drivers license says "Apt 304". That seems to be the favorite tactic to remove undesirables (any people with a skin tone darker than Rick Astley) from the list of eligible voters this year.
Thank you for making that point. The oil is far more valuable to us where it is.
The reason the Republicans want to drill is that it's not be more valuable to Exxon/Mobil or Chevron in that location.
The only thing we can do to appreciably affect the price of oil right now is to reduce our demand. Later, when we're sitting on the only unburned reserves, then we can name our price.
So, what, you're suggesting people who live lifestyles that cause heart disease are more likely to also use plastic containers for their food and drink? Or people with heart disease are more likely to use plastic containers? What other correllation are you proposing?
I rarely respond to people who can't figure out how to put their response outside of the quote tags, but here goes...
Perhaps people with heart disease also have reduced ability to metabolize or excrete bisphenol A.
At least you didn't have it in the U.S. Stock Market. There you would be down about $15K
Assuming he invested everything at the peak of the market, which is unlikely. Look into dollar cost averaging; it's amazingly effective at reducing variance from market swings.
What planet are you living on? That $15K is since January 1. Since the market peak it would be a hell of a lot worse than that. And dollar cost averaging doesn't really help a fairly steady decline or a fairly steady rise. In either of those cases you're better off staying in cash (steady decline), or fully investing on day 1 (steady rise). Dollar cost averaging is really only good as a strategy for those who wouldn't invest unless they do it once a month.
Those that did will tell you about how people went from being set for life to having nothing in the course of a few days.
Shit happens, but there are plenty of things you can do to reduce (not eliminate) the chance that you'll suffer from it. Thousands of people have died in auto accidents despite wearing seatbelts; does that mean there's no point in doing so?
That wasn't my point. My point was to caution him against congratulating himself prematurely for saving $80K. When you think you're smarter than everyone else in the market is when you're in the most danger of losing your shirt.
And he should realize now that if "shit happens" to him at the wrong time he'll be looking to the government for his social security check.
It's amazing that as someone who has never earned more than $48k/year (and that only in the last 4) in his lifetime, and is 36 years old, i already have $80k in the bank that will continue to grow and will provide for me in my later years.
I'm sure you feel great about that, but do you have that $80K in a bank, or an at risk investment? If you have it in a bank, you're probably earning about 1% interest, which means that you've lost $1K to inflation of far this year. But that's not a big deal compared to the $8000 you've lost in value of the dollar against other currencies. But at least you're insured against the bank going belly up. Until you put another $20,000 in the bank that is. If the bank does go belly up, you're only insured up to $100,000, which isn't a whole lot to retire on.
At least you didn't have it in the U.S. Stock Market. There you would be down about $15K (including losses against other currencies). If you do have stocks, do you keep the stock certificates at home? Or does your brokerage hold them? You realize that if your brokerage holds them, those stock you think you own are really assets of the brokerage. How much are they insured for if your brokerage goes under? Does your brokerage own a bank that is about to fail? Does a bank that is about to fail own your brokerage? Up until about 7 years ago there were laws preventing banks from selling securities or running brokerage houses, because back before the Great Depression arrangements like that caused a lot of people to lose everything and wrecked the economy for a couple decades. But for some reason, about 7 years ago some people in Washington D.C. decided that nothing like that could ever happen again.
You probably aren't old enough to remember a grandparent who went through the Great Depression. Those that did will tell you about how people went from being set for life to having nothing in the course of a few days.
funny how people think this is difficult.
The hardest thing in investing is avoiding the idea that you are smarter than all those people who lost everything. It may never happen to us. It may happen the day before you retire. You might think you'll just get a job, but if it happens like it did then, there won't be any jobs to get.
It's like the Zero-population gain folks, with their Malthusian scenarios.
You do realize that population growth will have to hit zero at some point, don't you? It doesn't matter whether growth is exponential or linear. Positive growth for infinite time is not possible.
The question is only whether population growth goes to zero in a controlled manner, or goes very negative in an uncontrolled manner.
Do you remember people talking about high food prices earlier this year? Do you remember people talking about high old prices? There is no food crisis. There is no oil crisis. There is, however, a "too f*cking many people" crisis.
The higher taxes are, the lower our GDP is and it's been found that the amount of tax money we bring in is directly related to our GDP.
Yes, conservative supply-side economists who write for the Wall Street Street journal are where you should go to get advice on how tax policy works. In other words, the sentence of yours that I quoted above is a pile of horse shit that is not supported by the evidence.
Such nonsense might give you a warm fuzzy feeling when you're counting your money, but it's no less a fairy tale than the rest of conservative economic theory. Reality is more that there is an optimal tax rate, and there is an optimal distribution of income, for the preservation of civic order and domestic productivity. As the years go on we have moved farther and farther from that optimum, to the point where national infrastructure, national defense, civic institutions and disaster preparedness are in the process of collapsing. And misguided individuals are promulgating the idea that it will get better as long as they we DON'T pay for improvements.
Reminds me of a story I heard on one of the news networks earlier this year. Someone was complaining that because building contractors hide a large portion of their income from the goverment by working for cash, many of them were not getting large enough "fiscal stimulus package" tax rebate checks.
I feel so sorry about how tax cheats aren't getting their fair share from the government.
Because unless you're there to learn about how other systems work, the computer is just a tool that is not directly related to what they're learning. When the specific choice of what tool is unimportant to what you are learning, you are better served using the tool you already understand or are comfortable with.
Are you going for a "+1 funny" or a "-1 stupid" moderation on this? Since the computer is a non-standardized tool you are better off exposing them to as many varieties as possible. Otherwise you're doing a major disservice. And yes, I've seen college freshmen afraid to use a non-microsoft word processor on a non-windows PC because "they didn't know how."
Imagine a wood shop class... Well, they're familiar with claw hammers, so we'd better not teach them what a rubber mallet is for. "Hey you! Put down that saw. Cut that board with a claw hammer the way we taught you!"
For one thing, different gadgets require different voltages.
Currently there are far more connectors types than there are voltages. It wouldn't be that difficult to standardize on one type of connector per voltage. Here's the tips my replacement laptop adapter came with.... Tips included: N1, N2, N3, N4, N5, N9, N15, N19. That's 8 tips for one voltage, and I assume all of the missing numbers (N6, N7, N8... N20...) are available for an extra charge. And unforunately there's no standard nomenclature for the tips. N5 for that adapter might be type K for another adapter.
I also have four different adapters with four different voltages (all center positive, one at 1.5V, one at 3V, one at 5V and one at 6.5V) that use the same tiny (and moderately rare) tip. The 1.5V is for a portable music device that runs off of a single NiCd cell, the 3V is for a PDA that runs on a pair of NiMH cells, the 5V is for a USB hub, the 6.5V is for a (non-mobile) phone charger. I once plugged the 6.5V into the USB hub by mistake, which destroyed the most expensive USB device I had connected to it. And this doesn't even count devices that use the same tip for AC or center negative.
My last phone (from LG) had a fragile plastic connector with about 30 pins that was used for every possible purpose. It was used for charging, but it couldn't charge from USB. It was used for USB communications, but you couldn't use USB and charge the phone at the same time. When that connector broke, rendering the phone useless after long enough to get a "free phone" from my provider, it was replaced with a new model, also from LG, that now uses a 10 pin connector for USB and for charging.
The purpose of this is not to keep people from buying 3rd party replacement power supplies, because you can find replacements every where you look. In fact it makes the people who sell replacements rich, because 5 years from now you won't be able to get a replacement power supply for either of those phones from LG.
Frankly I blame Apple. They really started the "every device needs a new non-standard power supply connection" trend with the MacBooks and PowerBooks. I think it was really the first sign that Apple had become evil. Shortly thereafter the Dell "3-pin" adapters appeared followed by the WinBook "4-pin" adapters.
I think it's time to demand a standard. Coaxial connectors for low voltage (<50V), low current (<10A) DC, each voltage with a different diameter, center always positive. LV AC should be on 2 pin connectors with a grounded shield, with different pin diameters and spacings for different voltages.
A mid-level employee signs a package and distributes it
What is a midlevel employee doing with the keys to the locked cage where the signing machine is kept? The signing machine should only be physically accessible to two people: the CEO and the one employee authorized to sign packages.
There's a reason you use cages for this purpose. It's so you don't even have to open the lock if there's a fire INSIDE the cage.
God, I seriously hope they don't have the passphrase saved so that you don't need to type it in to sign a package. If that is the case their security is very lax.
I don't know about anyone else, but I am surprised that their package signing machine is connected via a network to other machines.
Our code signing machine is locked in a cage and powered up only for purposes of code signing. Executables to be signed are written to a previously wiped USB drive which is attached to the signing machine only when packages are to be signed. The signing machine has not been connected to a network since before the keys were generated. The private key only exists on that machine and in a single separately encrypted backup.
I've always considered that to be a minimally paranoid means of keeping private keys private. Really paranoid would be "signed on one machine, checked and signed again on another machine."
This is also true for geothermal, ocean-wave, and bio-fueled energy. All can be generated locally, with local resources.
Ain't seen any geysers around here.
My father heats his house in Northern Wisconsin with geothermal energy. He used to extract the heat from the groundwater, but now he uses a recirculating system because the groundwater system was too susceptible to freezing.
During the summer he cools his house (on the three days per year it is necessary) by extracting heat from the air and storing it underground.
And there aren't any geysers in Northern Wisconsin. The groundwater is about 5C.
The problem is that the drives don't typically return an error when there is a sector read problem. It returns its best guess and then marks the sector as uncorrectable and "pending" relocation. Pending sectors get relocated the next time they are written. The md driver does not detect this condition and does not rewrite the stripe, so the condition persists. Bruce Allen (the author of smartd/smartctl) says he has been trying for some time to get the author of md to incorporate recognition of this condition. If you've got a new enough drive (one that supports a "write uncorrectable" command to write a sector with bad ECC to a drive) you can try it out for yourself.
On the other hand, good quality hardware raid controllers do seem to recognize and correct these issues, even if it is only when an array is verified. But you may have noticed that "verify" is not an option that the md driver supports. It supports two options... 1) rebuild a failed device 2) recalculate the parity blocks. The problem with 1 is that it requires the entire drive to be failed. The problem with 2 is that it assumes the data is good and the parity is bad.
If you're managing large arrays you see this "current pending sector count" condition far too often. You end up having to fail the entire drive and forcing a rebuild on a spare. Then you use dd to overwrite the entire failed drive, check to see that "current pending sector count" has gone to zero, Use dd to read the entire drive to see that the "current pending sector count" is still zero, and then either pull the drive to use it in some less critical task, or put it back into an array if you have a good feeling about whether it's going to keep working. DO NOT USE A DRIVE THAT HAS BEEN IN THIS STATE AS A SPARE! That is asking for trouble.
If it were possible to do a partial sync, maybe someone could write a tool to fix these problems. As far as I know, there is no way to get md to sync a single stripe (and if it were you would need to tell it which component of the stripe was bad).
about the chance of double failure on RAID5/6 growing with the size of the disk. Happened twice on my servers, exactly with RAID5+LVM+ext3.
Correct me if I'm wrong, but isn't the reason for RAID6 the ability to survive a double failure. Maybe the first time you got a RAID5 double failure should have been the day you switched to RAID6.
And are you really using ext3 for large filesystems? If I had 3 days to wait for a fsck to complete, maybe....
Where's the broken? No, really. I'm writing this from my lvm-over-md setup, 120mb/s read speeds (and I haven't done any settings tuning). What's the problem?
Well, to start with md doesn't talk with the SMART features of drives. When md gets an uncorrectable read, the proper and intelligent course of action would be recognize the error, get the correct sector values from the mirror (or calculate it from the other disk values on RAID4/5/6) and rewrite the sector which would probably prompt a relocation of the sector (assuming the write fails).
The current md course of action is to suspend the read until the drive is able to read the sector without error. Which will tend to be never.
All I can find on that is some references to how the plants growing under the telescope are growing a bit weird because of the electrical fields.
Can't find any pictures of the underside.
Also are not the reflector panels in a radio telescope little more than thin wire mesh?
When arecibo was built, the original dish was made out of chicken wire. But as the observatory started using higher frequencies, the holes needed to get smaller and the figure needed to be controlled better than was possible with chicken wire. The current surface is aluminum plates with machined holes. Depending upon where you are and where the sun is, 30 to 50% of the light is probably getting through. (And more importantly, all of the rain.) The spherical surface is maintained to a few milimeters RMS by the anchor wires you see under the dish.
Sorry, but modifying software is NOT copyright infringement
Sorry, but selling modified copies of copyrighted material most certainly is copyright infringement, unless you have a license to do so.
All you college students out there take this to heart... If you have written your name in your text book and you sell it to another student at the end of the semester, you are guilty of copyright infringement, and the TBAA is coming after your ass.
I suggest watching it. It explains everything, much better than I can do. Online here.
He tried to prevent the war, but there's only so much he could do.
He chose loyalty to the President and the Republican party over loyalty to the his country. That doesn't make him qualified to be president, but it does make him a typical Republican.

When md gets an uncorrectable read, the proper and intelligent course of action would be recognize the error, get the correct sector values from the mirror (or calculate it from the other disk values on RAID4/5/6) and rewrite the sector which would probably prompt a relocation of the sector (assuming the write fails).
The current md course of action is to suspend the read until the drive is able to read the sector without error. Which will tend to be never.
"Where's the broken?" There's the broken.
All I can find on that is some references to how the plants growing under the telescope are growing a bit weird because of the electrical fields. Can't find any pictures of the underside.
There are some pictures here.
Also are not the reflector panels in a radio telescope little more than thin wire mesh?
When arecibo was built, the original dish was made out of chicken wire. But as the observatory started using higher frequencies, the holes needed to get smaller and the figure needed to be controlled better than was possible with chicken wire. The current surface is aluminum plates with machined holes. Depending upon where you are and where the sun is, 30 to 50% of the light is probably getting through. (And more importantly, all of the rain.) The spherical surface is maintained to a few milimeters RMS by the anchor wires you see under the dish.
And no, I've never actually been in the pool.

All you college students out there take this to heart... If you have written your name in your text book and you sell it to another student at the end of the semester, you are guilty of copyright infringement, and the TBAA is coming after your ass.
I suggest watching it. It explains everything, much better than I can do. Online here.
He tried to prevent the war, but there's only so much he could do.
He chose loyalty to the President and the Republican party over loyalty to the his country. That doesn't make him qualified to be president, but it does make him a typical Republican.

The economy has boomed since the 2003 tax cuts...
I'm sure nobody could argue with that.
