You can't encourage people to... associate me with incompetence with stupidity, and douchebaggery.
No, only you can do that.;)
The bullies never like it when you hit back and it turns out you can hit back harder. Now his complaint is that they are doing the same thing to him that he asked his followers to do? Yeah, that is gonna suck for him.
The way I handle this is I greylist any email that comes in if: 1) it has no reverse dns 2) or the reverse dns matches certain patterns that indicate dynamic ip's
The rest comes in undelayed and is exposed to further checks. Note that it's ludicrous to require forward and reverse dns to resolve to the same thing. In today's age of hosting multiple domains in one server/cluster, it's just not reasonable to have PTR records defined that way.
You're blaming the wrong entity. If you're concerned with this, you should be complaining to your ISP _whom_you_pay_ that they use Spamhaus. You have control of your service, go buy it from someone who doesn't use Spamhaus. Spamhaus isn't screwing with your Inbox, your ISP _whom_you_pay_ is screwing with your Inbox by their choice to use Spamhaus.
Don't get me wrong, I think Spamhaus is one of the best things since sliced bread. Why does your ISP _choose_ to use Spamhaus? Because the extra cost and resources involved with NOT using Spamhaus would impact their bottom line and they would have to charge you more.

Chances are you didn't do the two main things that Linux requires for changing hardware out from underneath it: 1. Regenerate the modules needed at boot to access the harddrive(s). Cent/RH/Mandriva all have grub load an initrd with modules that the kernel needs to access the controller(s) and... 2. Change the module needed for network hardware.
Other possible issues are network device mac address change (Cent/RH tend to hardcode the MAC address into the interface config file), hostname changes, network interface reordering, adjust boot parameters to be friendly inside vmware, etc. These are small though compared to the two main ones above.
Electronics are pretty hardy and sturdy, helped by the fact that most boards nowadays are covered with a skin that protects from a great many contaminants. When I worked repairing electronics, we used a simple procedure:
1) Replace all electrolytic capacitors which were older than 7 years or had been exposed to continue high heat. In your case it was submerged, so it's likely that water got inside of them (they're vented) and they should be replaced regardless. 2) Remove any old style power transformers before cleaning. Modern switching power supplies are ok, much more sturdy. 3) We scrubbed boards with a toothbrush or small paintbrush using a mixture of water and simple green, though orange based cleaners work well too. We used about a 3:1 (water:cleaner) ratio. Then rinse with water and let air dry. The worst caveat is buttons or other things with tiny space which can hold water. We typically unsoldered those before we cleaned the boards, but if that's not your strong point, just make sure to dry everything before applying power again. A hairdryer and a few days of airdrying works really well in this capacity. Plus it also gives you time to see if mold returns, indicating a spot you should focus on. (I also never came across anything that the cleaner actually damaged, but be watchful for foam or other potentially dissolvable items. We were working on industrial electronics, so the manufacturing process may be a little different.) 4) Did I mention to make sure everything was completely dry before reconnecting and applying power again?
The whole reason for the GPL3 is to stop companies like TiVO. Some people object to TiVO being able to base a product on Linux but then not let the Linux community pull it apart and play with it.
The source code for the Tivo IS freely available. The hardware does a check for validity of the kernel and refuses to run it if it doesn't match expected values, but that's hardware. That hardware is not and never has been covered by the GPL. The GPLv3 is an attempt by RMS to expand the scope of control and legislate hardware interaction with the software. I can see that the reason they need a new GPL is because this is contradictory to what the GPLv2 stood for and stood against. So where does it stop? Your refrigerator will be turned off because you use a brand of orange juice that RMS is against?
That's why the market should be deathly afraid of a Blue-Ray DVD victory. No chance of that happening. If it's true that Sony is dead set against Blue-Ray pressing plants actually producing Porn DVD's, then HD-DVD will win hand over fist.
I've always been curious why more people don't use gas.
I'm trying to keep this as factual as possible, but it does go off on a tangent. Be kind with the modding.
In the past it had more to do with regional availability and perceived safety issues. In the future, it's going to be because we're competing with power plants for dwindling natural gas supplies. The US is growing its electricity production capacity, mostly with coal plants, because they foresee a tightening of natural gas supplies. Canada is a large supplier, and they've managed to nearly deplete one of their minor reservoirs of natural gas (2% of their gross deliverable gas, it feeds the Northeastern US) in only 10 years http://www.theoildrum.com/story/2006/10/23/73422/6 86. Currently the US public is exhibiting NIMBY behavior against LNG terminals, but that's mostly because they don't realize how precarious the natural gas delivery is going to be in the next 5-10 years (very little spare capacity to absorb the constantly growing demand). Unless the Canadian tar sands have lots of natural gas in and around them, we're going to see some costs start to rise at levels that will likely cause economic shock globally (which could cause the demand to subside, but only due to a gradual lowering of living standards).
Spamhaus gives only further sub 5% improvement on top of greylisting
You assume that your customers won't leave en masse because "my sister just sent an email and it didn't get here 30 seconds later". When you tell them that cannot be changed, they will leave and go to someone who accepts and delivers email instantly. It doesn't matter that it is in their best interests, they will still leave. We can't do greylisting for that exact reason.
Here's what kind of stats SpamHaus does for us:
Blocked from SpamHaus (hijacked cable/dsl modem): 160039
Blocked from SpamCop RBL: 7869
Blocked from internal RBL: 1145
So before even seeing content, we blocked 169053 connection attempts, and there could have been multiple emails on each connection. After all that being blocked, we still accepted 55K emails:
Inbound per day totals: 55373
Detected and rejected as spam 37677
Detected and rejected as virus 254
and there was STILL 38K emails detected and blocked as spam. And in the real world, some of that 17442 emails (55373 - 37677 - 254) was spam too. If we open the floodgates and previously blocked email starts getting delivered, likely it would be about 100K emails that get past the spam filters, of which all additional email is guaranteed to be spam, so 80%+ of that delivered email would be spam.
Now, multiply those numbers times 4 and that is the load we would have to deal with, and we are a small operator compared to a lot of ISPs. In addition, we would likely have to get one or two additional machines to handle the increased spam scanning load. It does nothing but COST US MONEY to shut down SpamHaus service.
Before anybody points out the obvious, our SMTP Auth users are exempted from the RBLs if authentication succeeds.
One thing that I've not seen anybody mention though is how simple it is to make your nameservers forward spamhaus.org requests to their nameservers. Problem solved.
When I heard Bush say that it suddenly made perfect sense: two sides, both of whom have an interest in a war that is by definition practically unwinnable. And the leader of the most powerful nation on Earth claiming the blitherings of a man hiding in a cave constitute a creditable attack on our world-spanning civilization. Neither is interested in victory. Both are interested in pervasive warfare and fear. That is what secures their own power-base.
Having just read 1984, it's eery how closely your analysis compares with the writings of Goldstein. All sides want a war that is continuous and unwinnable, but spinning the results with propoganda espousing that we are winning a glorious victory.
I frequently wonder if the Dixie Chicks will one day be held in high esteem for having had the courage to stand against the lawbreaker Bush (the younger one, the older one actually seems to have been a good old fellow). I'm reading more and more about impeachment of Bush Jr. It could happen, but I honestly don't see it moving forward fast enough to actually come to a resolution during his Kingship^W Papacy^W Presidency.
We've found that 512 Megs of swap is more than enough for our 2 and 4 Gig machines. Why even have swap? Here is an example:
1) On a system with zero swap, when apache gets slammed (say you get to the top of digg or slashdot), apache starts consuming lots of memory to handle new inbound requests. When it runs out, the machine grinds to a halt because it can't allocate more and requires a power cycle. (Setting a low max children really only helps if you are happy denying traffic to the people who are trying to see your site...it's best to plan for capacity and put quite a few servers load balanced). 2) On a system with any appreciable swap (IMHO, more than 128 Megs, up to 512 Megs), if you're monitoring the system (watch -n 1 df -h, for example) and all of a sudden it starts using swap, the machine is on the edge of dying. This gives you an early warning that maximum machine performance/throughput is occurring. You can restart apache or shut it down or similar, you can do something to temporarily lower or remove load from that machine. This doesn't give you *much* time, but it gives you some.
In our real world experience, at digg and slashdot loads you have about 10-15 seconds to stop apache once it starts swapping. After that, the performance degrades so bad that the machine becomes catatonic, the same as #1, requiring a power reset (obviously because virtual memory on HD is magnitudes slower than RAM, as numerous others have suggested). The key here is that you must realize that some swap is good for allowing unused programs to be swapped out, such as login terminals that just sit there. It's great for detecting problems, but if your heavy app is the one utilizing swap, your machine is about to crash anyway.
277/480VAC power distribution involves 3-phases of current which are 120 degrees out of sync with each other and a forth wire for neutral. In order to get 120VAC, you just need to connect between one of the phases and neutral; you don't need a step-down transformer.
Ummm....No.
1) 480 3 phase can be 3 wire or 4 wire. 3 wire is called Delta (floating ground or one of the legs can be tied to ground). 4 wire is called Y (typically the 4th wire is the "center" of the Y and is grounded. 2) You get 277 VAC reference to ground with Y. You get nothing stable with Delta floating. And you get 480 VAC or 0 VAC with Delta one leg grounded. I'm not advocating one way or the other, it depends on a lot of things which configuration you choose. 3) Either way, to get 120 VAC, you have to use a transformer to reduce the voltage. Phasing is not adusted. If you have 480 VAC 3 phase, you'll get 120 VAC 3 phase, though that's misleading because you always connect 120 VAC 3 phase in the Y configuration and measure 120 reference to ground, not phase to phase. The actual number phase to phase is some weird number I can never remember like 177 or something. 4) Corrolary to #3, in a home system, you have 240 VAC which is really only two 180 degree phased 120 VAC lines. To get 240 VAC 3 phase you need a specific transformer which will have seperate taps to provide 120 VAC if you so desire (or just use two different transformers to achieve it).
If "changing plans" means "gets switched to a different VLAN", then it's quite possible that he's moving from one VLAN that's 400% oversubscribed to a different VLAN that's 400% oversubscribed. ISP configuration is a lot more complicated than just "one big pipe shared by all".
They stand in line, they shell out money for tickets, and resell them. They peform a useful service for those of us who can't stand in line...
You know, there's this thing I heard of once called the Internet. A really smart ticket selling company would make it so that you could just logon to their website and buy those tickets online without making you go physically stand in line. I think I'm going to go work for TicketMaster and get that added to their website ASAP. I'll become the richest manager ever!
Kids hating to go to school and/or do their homework isn't a problem with the kid. It's a problem with the teachers and parents. They're being dumbasses, adopting behaviors of their own that necessarily drive the kids away from the behaviors they wish the kids to adopt.
Because they do not want the kids to mature. They want them to shut up and do as they're told; and right now we have a society that tells them this is the way they should behave until their eighteenth birthday, when they are then supposed to automagically transform into responsible adults, without ever having taught, or evern offered the opportunity to learn on their own, just how to do that.
go to one place all day long (and don't do anything productive, as in do something for the good of your family)
infantilizes them ("shut up and do as you're told")
For the most part I agree. Education has already been crushed into the instutionalization approach. Much of the problems stem from the want/need of parents to also shrug the maturation of their children onto the instition's shoulders as well. That can't work. Parents need to be more active in their kids lives. And that's hard to do when both parents need to work to make the inflated mortgage (or rent) payments.
In the US, people are very spread out. Our rail system pales to other countries, especially ones with advanced modern rail systems such as Japan. Rail in the US is used mainly for freight shipping between distant parts of the country and not as much for passenger.
You can thank General Motors for the systematic dismantling of the rather intricate rail system that existed in the Northeast in the early 1900's. They also affected the west coast as well. Two years ago Los Angeles made a big deal about a new commuter rail line that opened. They built the tracks on the same land that the auto industry had ripped out the tracks in the early 1900's. The really sad thing is that ridership on that line is half of what they had projected.
I know for myself a round-trip train ticket from Albany, NY to NYC would cost around $150. The same trip would be equivilant to about $60 in gas. I'm all for the environment, but the cost of rail is not the way to solve it.
Agreed. We will start to do rapid development of public transit systems once the price of oil climbs above $100/bbl and stays there. How long before that happens? Kinda depends on when the world realizes that Saudi Arabia's oil production has peaked and a) can't "fill in" production holes from other countries and b) in a few years starts to decline For both of those, oil shortages will occur which will result in oil price spikes and (chemical processing) production disruptions, which will result in price spikes from everything directly made from oil and natural gas (plastics, fertilizer, gasoline, diesel) and everything reliant on those (farming, medicine, airlines, COMMUTING, etc)
The point is, public transport just isn't available in a very large portion of the US. I don't have the option for a bus or train. There isn't one anywhere near my house that would take me to work. A lot of Americans have the same issue. We would use it, if it was around, but it's not. The reason it isn't available is because the geographical distance is just too large to cover with an effective public transport. It's unfortunate, but how it currently is.
Again, this is thanks to the systematic dismantling of burgeoning rail systems by the auto industry in the early 1900's. Those who are poo poo'ing the auto industry for all the trouble there are in right now don't take into account the fact that the auto industry had a large part in putting us in the position of such extreme reliance on oil.
For all who are interested, may I suggest some scary reading? They can be found quite easily on Amazon.
"The End of Oil"
"The Long Emergency" They focus on facts and it gives you a view that is rather unsettling. In my reading, the first book has a centrist slant and the second book has a centrist left slant. There is some supposition in both books as well, but it's after the facts have been presented and merely "discusses" the possibilities, not "brainwash" you with their version of the future.
At first I thought you said Capitol Punishment... You could blindside a few politicians whose districts the bulk email corporations are registered in. But no, regulation is not the answer. Government has screwed up so many things that they stuck their fingers in, I don't want them touching this.
If it's anything like previous video issues, I see licensing being pursued for MPEG-4 compression only. I don't see them pushing licensing for players. Decompression is the desired end use, so why do things to hamper that end goal? There's no money to be made forcing the players to pay for using decompression, because players will just stop using that technology (such as switching to Real as the standard, who give away the playing technology, or at least the files to do it). Witness MS and the defacto acceptance of WMV which internally is MPEG-4 part 10, but they can do that since they internally developed much of the spec that enhances it and makes it "part 10". MPEG-4 part 10 is an enhancement to MPEG-4 so it undoubtedly also relies on some or all of the core patented function. So...
Is MS paying their licensing costs for the privilege of enhancing their video format? Have they already paid? Was it a gratis license (in an effort to inject the MPEG-4 format onto millions upon millions of computers via a monopolistic desktop)? Is MS about to get hit upside the head with a lawsuit that they might actually be a victim that Slashdotters would feel sorry for?
I don't know the answers to those questions but would be interested to find out.
http://en.wikipedia.org/wiki/U.S._presidential_ele ction,_2000 Due to the way our electoral system works, it went Bush's way due to the 537 vote victory in Florida, getting him the needed votes to surpass the 271 count electoral vote requirement. The issue at hand was that the Gore camp called for a recount in 4 counties in Florida, 4 counties which were heavily Democratic, but the final margins didn't indicate that heavy bias.
Do I think we would have been better off with Gore? Now, maybe. Short term, no. Long term, yes. But that's just my particular view.
Do I lean left? Absolutely. Bush cut taxes to stimulate the economy. Reagan showed that cutting taxes works great to stimulate the economy. But then Bush spends and spends like there's no tomorrow (increasing national debt).
http://www.financialsense.com/fsu/editorials/2006/ 0206.html Basically Japan did in the 90's what we're doing now (ultra low rates and print money as fast as it can). They still haven't recovered and are under a huge pile of debt as a result. The only reason they're climbing out now is because they can export product that they can create because of the pool of cheap labor. Here in the US, we do not have that cheap labor.
To paraphrase, we in the US are on a downward trend to equalizing our standard of living with the rest of the world. It's only natural of those in power to fight it, but it's a losing battle. Remember, finite resources...
It doesn't matter what kind of solutions are devised for energy consumption. Our economy is based on growth, and that growth is based on the destruction of consumable resources. We live on a planet with finite resources and finite ability to sink the by-products of that consumption. The only long-term viable solution for this scenario is:
a social change to a lower standard of living
lower the population, a hugely irreverent and unacceptable proposition, but maybe Mother Earth will flex her muscles and get rid of a large chunk of us on her own accord (remember, she just created us because she wanted plastic:-) )
Go read http://www.peakoil.com/ for an eye-opening view of the signs and statistics that our economy is showing us. Remember that the people on this site tend to slant pretty far left, nearly the same capacity that the ruling Dictator Bush slants too far to the right. Somewhere in the middle lies the ultimate truth, but that middle is scary because the reality if this "reckoning" is not but a few years off. The beginnings of the creaks and cracks of our world economy have been starting to show for quite some time. Dictator Bush has made it much MUCH MUCH worse, but he's not the only one to blame here. Some accuse Greenspan of setting up this fall we're about to have, but he's not the only one, there's lots of complicity here.
Starting out life as a good little Catholic boy, I've slowly moved to the position that I'm now anti-religious. http://whatstheharm.net/ My Dad is not happy with me, but he prays for me to see the light.
No, only you can do that. ;)

I would refute this, but I'm too sleepy and hard to bother with it.
Ummm....No.
1) 480 3 phase can be 3 wire or 4 wire. 3 wire is called Delta (floating ground or one of the legs can be tied to ground). 4 wire is called Y (typically the 4th wire is the "center" of the Y and is grounded.
2) You get 277 VAC reference to ground with Y. You get nothing stable with Delta floating. And you get 480 VAC or 0 VAC with Delta one leg grounded. I'm not advocating one way or the other, it depends on a lot of things which configuration you choose.

I think I'm going to go work for TicketMaster and get that added to their website ASAP. I'll become the richest manager ever!

For the most part I agree. Education has already been crushed into the instutionalization approach. Much of the problems stem from the want/need of parents to also shrug the maturation of their children onto the instition's shoulders as well. That can't work. Parents need to be more active in their kids lives. And that's hard to do when both parents need to work to make the inflated mortgage (or rent) payments.
You can thank General Motors for the systematic dismantling of the rather intricate rail system that existed in the Northeast in the early 1900's. They also affected the west coast as well. Two years ago Los Angeles made a big deal about a new commuter rail line that opened. They built the tracks on the same land that the auto industry had ripped out the tracks in the early 1900's. The really sad thing is that ridership on that line is half of what they had projected.
Agreed. We will start to do rapid development of public transit systems once the price of oil climbs above $100/bbl and stays there. How long before that happens? Kinda depends on when the world realizes that Saudi Arabia's oil production has peaked and
a) can't "fill in" production holes from other countries and
b) in a few years starts to decline
For both of those, oil shortages will occur which will result in oil price spikes and (chemical processing) production disruptions, which will result in price spikes from everything directly made from oil and natural gas (plastics, fertilizer, gasoline, diesel) and everything reliant on those (farming, medicine, airlines, COMMUTING, etc)
Again, this is thanks to the systematic dismantling of burgeoning rail systems by the auto industry in the early 1900's. Those who are poo poo'ing the auto industry for all the trouble there are in right now don't take into account the fact that the auto industry had a large part in putting us in the position of such extreme reliance on oil.
For all who are interested, may I suggest some scary reading? They can be found quite easily on Amazon.
"The End of Oil"
"The Long Emergency"
They focus on facts and it gives you a view that is rather unsettling. In my reading, the first book has a centrist slant and the second book has a centrist left slant. There is some supposition in both books as well, but it's after the facts have been presented and merely "discusses" the possibilities, not "brainwash" you with their version of the future.
At first I thought you said Capitol Punishment...
You could blindside a few politicians whose districts the bulk email corporations are registered in.
But no, regulation is not the answer. Government has screwed up so many things that they stuck their fingers in, I don't want them touching this.
I am not an expert at video.</DISCLAIMER>
If it's anything like previous video issues, I see licensing being pursued for MPEG-4 compression only. I don't see them pushing licensing for players. Decompression is the desired end use, so why do things to hamper that end goal? There's no money to be made forcing the players to pay for using decompression, because players will just stop using that technology (such as switching to Real as the standard, who give away the playing technology, or at least the files to do it). Witness MS and the defacto acceptance of WMV which internally is MPEG-4 part 10, but they can do that since they internally developed much of the spec that enhances it and makes it "part 10". MPEG-4 part 10 is an enhancement to MPEG-4 so it undoubtedly also relies on some or all of the core patented function. So...
Is MS paying their licensing costs for the privilege of enhancing their video format? Have they already paid? Was it a gratis license (in an effort to inject the MPEG-4 format onto millions upon millions of computers via a monopolistic desktop)? Is MS about to get hit upside the head with a lawsuit that they might actually be a victim that Slashdotters would feel sorry for?
I don't know the answers to those questions but would be interested to find out.

Bush: 50,456,002 47.87%
Gore: 50,999,897 48.38%

Due to the way our electoral system works, it went Bush's way due to the 537 vote victory in Florida, getting him the needed votes to surpass the 271 count electoral vote requirement. The issue at hand was that the Gore camp called for a recount in 4 counties in Florida, 4 counties which were heavily Democratic, but the final margins didn't indicate that heavy bias.
Do I think we would have been better off with Gore? Now, maybe. Short term, no. Long term, yes. But that's just my particular view.

And yes I do consider Bush a dictator. Suppression of science based on religious views speaks loudly to that effect.
Do I lean left? Absolutely. Bush cut taxes to stimulate the economy. Reagan showed that cutting taxes works great to stimulate the economy. But then Bush spends and spends like there's no tomorrow (increasing national debt).

Basically Japan did in the 90's what we're doing now (ultra low rates and print money as fast as it can). They still haven't recovered and are under a huge pile of debt as a result. The only reason they're climbing out now is because they can export product that they can create because of the pool of cheap labor. Here in the US, we do not have that cheap labor.
To paraphrase, we in the US are on a downward trend to equalizing our standard of living with the rest of the world. It's only natural of those in power to fight it, but it's a losing battle. Remember, finite resources...
Go read http://www.peakoil.com/ for an eye-opening view of the signs and statistics that our economy is showing us. Remember that the people on this site tend to slant pretty far left, nearly the same capacity that the ruling Dictator Bush slants too far to the right. Somewhere in the middle lies the ultimate truth, but that middle is scary because the reality if this "reckoning" is not but a few years off. The beginnings of the creaks and cracks of our world economy have been starting to show for quite some time. Dictator Bush has made it much MUCH MUCH worse, but he's not the only one to blame here. Some accuse Greenspan of setting up this fall we're about to have, but he's not the only one, there's lots of complicity here.
Yes, Preparation H DOES feel good on the hole...
