Or just stay out of Europe. In case you've not seen the news lately, the EU is turning into a pretty violent place with citizens attacking police & vice versa.
I heard the US is full of mad people with big guns who keep going to McDonald's and make the larger carnagge ever.
There, are we done with stupid stereotypes? Or should we Europeans continue counter-attacking with the stupid lost American tourist?
Only on slashdot - stupid and desperately misinformed stereotypes modded 5 insightful.
As a former BMW car owner and current BMW motorcycle owner, my experience is quite the opposite. Not cheap indeed, but not expensive either and at all times very professional. I claim no serious study but my company owns a Smart (which is maintained by Mercedes, at least here in Spain) and I find BMW far more reasonable.
I beg to differ, ensign Crusher. Many fatal crashes on small (propeller, single engine) airplanes could be avoided if the pilot had taken gliding lessons. Also, small and low altitude have a high correlation but, as usual, correlation is not causation - many small airplanes out there can fly into altitudes on which loss of pressurization leaves precious little minutes of useful conscience before hypoxia makes the pilot lose it. Unfortunately, high performance requires altitude - that's why the airliners take the trouble to go way up there.
Not sure about "crappy". It's a classic of its genre and, just like the books, has that feeling, typical of the time, that the author smoked something really weird while writing some parts.
What efficiency? That of the manufacturer's sales team?
A series diode is only a 0.6V drop and, for low-power devices like these, its power use is comparable to all those fancy LEDs in the front. Only that none of these LEDs will protect the device from plugging the wrong supply.
ADSL modem and ethernet router, same brand. Same connector for the DC power supply. Opposite polarities. So if they were ever unplugged at the same time there was a 50% chance of letting the magic smoke out, which did happen.
A pair of devices so brokenly designed can't, of course, include a series diode. Oh no, that would cost one more cent per device - prohibitive!
As a 3rd gen Prius user, I beg to differ. Granted, it's not the addictive feel of a BMW coupe, but it feels just fine and if I have to find something needing improvement it's the initial response. But I am rather pleased with this car's handling and especially its power steering, all things considered.
So if Intel is now pushing the Pentium brand, and having suffered Intel's legal belligerence myself, I feel sorry for all those who have brand names starting with P and having less than 12 letters.
You say that as if it was a great thing. What is so cool about everyone in a country with a nine-digit population (which statistically makes the percentage of insane people millions) being able to have deadly weapons with them at all times?
Personally, in that regard I feel much more secure in my country (which is in the EU, by the way) because people can carry guns if: (a) they work for the police, (b) they work for the army (and then not at all times) or (c) has been life-threatened, and a judge decides the threat is serious. All of them have to pass an exam to assess their suitability to carry guns, kind of ensures his/her sanity. Add to that another special permit for sports, which does also require an examination, and allows only for certain classes of weapons and ammunitions. Net result? No guns in the streets. Almost no deaths by gunfire. When there is a shot in the street, it hits the news because it's so rare.
How does an organization that works with moderately complex technology, where security is of the utmost importance, go down such a dark alley so many others have treaded before with foreseeable and dreadful consequences? Point-haired bosses? perhaps appointed by politicians? Too good a business to think about the pillars? Seriously, did they never ever have anyone raise the alarm? What happened if someone did?
Your first statement is true. As for IPv6, I don't see IPv6 as making a case for multicast globally, perhaps unfortunately. Even the contrary may be true: Since deploying IPv6 costs large sums of money, multicast will have to wait. Also, multicast and IPv6 have little in common that can create synergies; it's not as if IPv6 brought by design a multicast proposal that was radically more convenient than with IPv4.
Very. It's content delivery in real time, latency optimized, what this is about. P2P, using residential low-speed links and desktop computers, is simply not suited for the task.
What is not is new. Distributed content caches were all the rage at the end of last millennia - everybody remembers about Squid, I guess? - and DNS geo load balancing (including fancy boxes with large price tags), and all that stuff. Ever fatter pipes have always reduced the need for this sort of solutions and my guess is that it will continue to be the case.
Multicast is another example of a technology that was created to improve content delivery, basically for audio and video. Almost nobody uses it. Instead, CDNs distribute unicast feeds globally. It was also a good idea, but it required a ton of resources and a different thinking than traditional routing.
Guys, someone else is offering a free hypervisor with goodies. Quick, rename and split again everything. And let's make a few things other than the hypervisors actually work this time!
2. A block of 24-32 ip numbers. (49 ip numbers would be ideal, but it's harder to buy odd blocks like that.) Put your mail server as close to the middle of that range as possible. It sounds like a lot, but most collocation facilities can hook you up with this for 300-500 usd a month.
While most of your advice is sound and I can understand your frustration with running e-mail servers, I think that the quoted part is ill advice.
You are going to make a hoster rich for no good reason at all.
I manage some IP space (by that I mean something bigger than a couple servers here and there). Parts of "my" space, predictably, have significant e-mail traffic. This introduction is just for you to give me the benefit of probably knowing what I'm talking about
Yes, there are a few blacklists so stupidly managed that they will blacklist a whole block if they get hit by a single IP on that block - and by the way, the block size that those morons usually choose is not 50 IPs, but more often 256 - yet another remainder of the classful days that resists to die. And this is the reason why few people use those lists, and are therefore not a usual problem. In the rare occasion where one of my mail servers, or other people's mail servers in "my" IP space, hit something like that and I need to be involved, I inform our user(s) and the other party of the situation and make it very clear both to our user(s) and to the other party whose problem is it to solve (with rogue black lists, definately not ours), and that if they stop using blacklists managed by former members of the nazi party, they will be much better off with not measurably more spam, provided that the rest of their side more or less well implemented.
Aside from the network, I manage directly a few mail servers. While it's a never-ending work to keep them tidy (with most of the work being indeed made one time at the beginning), it's not horrible. I know because managing mail servers is not near the top of the list on things in which I spend my time, by far. Which is why I keep doing it, despite the valid reasons many posters have explained in favor of Google Mail or some other big provider, and despite not being the focus of my job.
Currently, my recipe is graylisting+SPF+reverse deliverability tests+a few obvious compliance tests+a couple sane black lists+two white lists (one in-house, one community)+fail2ban, running on Postfix and Dovecot, and Roundcube for webmail users. The only thing that from time to time causes me to look at logs is the reverse deliverability tests, and I could do without them, but I choose to be a little bit less flexible there. My implementation is based on the excellent workaround.org tutorials by Christoph Haas which I already recommended, I think, on this same discussion.

Luck is something that eventually happens to mail admins that work hard enough. Which granted, can be hard and unrewarding, but if you want it you get it.
We are not getting much in the way of IPv6 here in Spain, either. The biggest telco is deploying that contraption dubbed Carrier Grade NAT. The only way to have IPv6 here behind an ADSL is to get the service from one of the smaller providers... Who pay dearly for the right to use the cable, which belongs to the big telco, who from time to time makes a mistake that breaks things badly, but only for cables rented to other companies. I'm talking from (long, sad, enraging) experience here.
3.5 MB is still overkill. Any printer which is not bottom end or for any reason needs extensive work on the computer side of things (that is, most printers) could work with a driver which is no more than a few dozen kilobytes in size. Take a look at old LaserJet III PS drivers which date back to before the bloatware. I have been unable to find those on HP, but I found a Postscript driver for Windows XP for the LJ 4, 5 and 6 which is 0.9 MB in size. Didn't test it as I'm on Mac OS X, don't have a printer here, and I think its existence is enough to support my point.

I might as well, if Thinkgeek finally got their act together and shipped to Spain.

Thanks Commander Data. That was very informative.

Electric power steering feels like crap, though
As a 3rd gen Prius user, I beg to differ. Granted, it's not the addictive feel of a BMW coupe, but it feels just fine and if I have to find something needing improvement it's the initial response. But I am rather pleased with this car's handling and especially its power steering, all things considered.

you can have guns

Almost no deaths by gunfire. When there is a shot in the street, it hits the news because it's so rare.
So, I am walking down the street, in the next block someone lifts a wallet and I have to pay for the wallet just because I'm on the same city?
They chose to simply moderate +1 instead, while two suspected PTR-less postmaster wannabes moderated -1 Troll. Oh well, such are the Slashdot ways.
Incompetence.
Cisco sells packaged services. If they cover the need, then the provider is not relevant.
