btw. try convincing most of the population that microwaves don't cook from the inside out. That's how the media portrayed them as working for *years*. Because a man in a white coat told them 5 years ago they worked like that they will *not* believe it has anything to do with water - believe me I've had discussions along those lines and gave up.
For 99% of people it's an oven. You put things into it and they get hot. For a microwave they get hot very fast, compared to a gas oven.
People know not to put eggs into them and not to use anything with metal on it. As far as how they work... I'm fairly technical and there's no way that I would have assumed that you had to wet the sponge first.. bacteria cells contain water don't they (I'm not a doctor so don't know.. it seems maybe they don't from what others are saying). OTOH I wouldn't have put it in there for more than about 30 seconds, and I'd have been watching.
The article stated that by putting a sponge (one article I saw said dishcloths) into a microwave it would kill all bacteria.
No mention of wetting it... just zap it and it sterilizes it.
I really don't think that people were being stupid. They made the mistake of trusting the media to report the facts (which I guess could be considered stupid) and not leave out vital details like 'the sponge must be wet'.
I read it as the soaking in bacteria was necessary setup for the experiment, not that it was a requirement for it to work.
Nowhere is soaking in clean water mention either, if you want to be that pedantic about it.
Luckily I never tried this... I wouldn't have soaked the sponge in water.. guessed it might have worked because bacteria cells contain water but the articles were so vague as to contain no details whatsoever.
The problem is they'd try to 'monetize' it. Verisign would get first pick, and would get all the juicy ones. Then a thosand registrars would compete in the 'services' domain for different words. Then you'd get registrar squatters...
Also you wouldn't be able to add a new category under 'services' without ICANN approval (because it might 'destabilise' the internet) so we'd be left with 5 or 6 (sex, gardening, computing and probably a special one for museum with one domain in it).
There are ways of not doing so... for example putting bits of the key in different places in the memory map. Putting crucial bits of the key in kernel memory where userspace can't read it... deliberately obfuscating parts of the key (eg. xor the 10th byte with some value, thus invalidating it unless you know that it's been done).
TPM will hold the key in unreadable (to unauthorised applications) static memory. Once that gets on your PC you've got to crack TPM first.. and that's going to set you back *at least* half an hour:p
Nah.. been doing that for years (or I was before HD became available in this country - it was the only way to use the expensive HD TVs they'd been pushing us).
Leaving a couple of films on overnight download really is no hassle, unless you're on bandwidth limits (alas, nearly all ISPs here have them now.. they call them 'unlimited' and in the small print you get 'subject to 1gb usage cap'. My own ISP only has a cap during business hours though).
Satellite TV encryption is dynamic. Got the keys? They just got revoked. Worked out the encryption? A download just changed it.
A DVD is a static medium and the players aren't normally connected to a source of data, so they can't update them so fast, and they can't invalidate the encryption without making your existing disks unplayable (=class action lawsuit)... so it's considerably easier to break (and re-break as they issue new disks).
Try sending a word 6.doc to a vista user. Oops they have to pay for office to read it because your 'backwards compatibility' doesn't work and wordpad on vista no longer supports.doc.
Try sending an office 2007 document to a word 6 user. Oops they have to upgrade to office 2007 because 'backwards compatibility' doesn't work.
MS *rely* on breaking compatibility to force people into the upgrade cycle. If they didn't everyone would still be on Office 97, which was the last decent office package before the bloat exceeded the usefulness.
OTOH There are practical reasons not to - too many newbie admins who don't realize what a reverse DNS name even is. Many of them working for fortune 500 companies.
It probably eliminated half your legit email as well.
The problem with forcing retries is not every server *can* retry (typically relays like antispam devices which have no actual queue, but even MS Exchange has this problem under certain configurations, and I found out once (got an email bitching about me bouncing email from a large company that was running Exchange..)).
Of those that do retry, 24 hour retry times are not uncommon (my own are set to 4 hours, so holding a conversation by email with you would be impossible).
Yuk. I can *legitimately* easily send 25,000 emails in a day (1000 user mailing list, 25 messages).
That comes out of my bandwidth cost, that I've already paid for. ISPs shouldn't be double dipping and expecting you to pay *again* for specific usage of that bandwidth.
We need to go after spammers not screw around with legitimate use of the internet.
They're thoughtless assholes with one goal in mind: to make a profit.
No, they're thoughtless assholes with a deathwish.
If they wanted to make a profit then pissing off their customers and having their online business crippled because they can't send email and even (quite likely these days) having their internet connection terminated for breach of contract is not the way to go about it. No profit involved.. in fact the damage to a smaller company if that happened could be fatal.
I once had to explain that to marketing. They got it when they realized that short term profit wasn't worth having no job at the end of it. It also helped that our server admin flat out refused to be involved and said he'd resign if they tried it.
Nah they always have done... TFA works under a false premise (that spammers target the primary MX). In reality they target the secondary MX becuase that's more likely to have weaker/no spam protection on it.
IPV6 mailservers are like hens teeth. I actually list ipv6 addresses for mine... and the number of connections over ipv6 in the last 6 months? (bearing in mind this is a relatively busy server). Zero.
Because spammers may be directly targeting an IP address, one other possible way to fight spam is to change the IP address of your SMTP server regularly. If you change the MX records (well, really the A records they point to), legitimate traffic will pick up the changes. To be safe, you can continue to listen on the old IP address for a week or so while you make the transition to the new IP address. That ought to give stale DNS entries plenty of time to expire
The problem with this is DNS propogation.
I usually reckon it takes 24 hours for the majority of ISPs to pick up the changes in a DNS record (using a standard 8 hour TTL). 36 before you can start telling people to bitch to their ISPs to fix their DNS.
Some ISPs are just totally broken and won't update a record unless they're kicked (demon used to be terrible for this.. once they'd cached something it stayed that way... TTL be damned).
If you change too often you're going to get bitten by this a lot.
I had a domain that was out of use for about 18 months (company domain... they still paid for it but there were no MX or A records).
The mailserver was still getting spam for that domain at the rate of 2-3 *per minute* even though there hadn't even been a domain to speak of for all that time. Not only that since we were hard bouncing it as nondeliverable it proves that spammers don't care whether they get a bounce or not.. they'll just keep trying, for ever and ever.
Greylisting has to high a false positive rate (many legit servers do *not* retry, and those that do sometimes have a 24-48 hour retry rate), and an insanely high false negative rate (99% of spammers know to retry lots of times).
Fine if everyone was using sendmail, postfix, etc. then it might work, but try telling a million dollar company *their* email must be broken because *you* bounced their email. You'll be able to hear the laugher from miles away...
If one thing is almost certain, grid power is not going to get cheaper in the next few decades. I think the British slashdotter's can attest to the level of their recent utility price hikes, here in Australia our PM has recently warned of similar future rate hikes of up to 40%.
The price hikes here were our own fault. We had abundant natural gas, so the short sighted politicians sold the lot of it at inflated prices to europe & kept the profit. Now we've run out (about 200 years too early) and now the consumers are getting it in the shorts because we're paying even more than we made in profit selling it to buy it from places like russia... the politicians make even *more* money by taxing the gas as it enters the country.
7-11 years depending on the region, installation, etc for a suitable system. Usually longer than most people own a house. This is the primary reason why they are so rare.
Also the cells themselves fail after about 11 years.
So just after paying off your expensive solar panels, they break and you have to buy new ones....

Floating animated penises are 'sexually explicit'? Huh?
They're about as 'explicit' as a carry-on film. You'd have to be really sheltered to be remotely shocked.
Not to mention slahsdot.org

So more of the same then.
Hmm... 3 minidisk players, no DCC players (or did you mean DAT? same answer but probably for different reasons).
The problem is ask 10 slashdotters and you'll get 10 answers to this.. so I don't know what you were fishing for...

Heh. So I'm not a murderer I'm a 'Population Control Assistant'.
Yeah. That'll fly.
Try sending a word 6 .doc to a vista user. Oops they have to pay for office to read it because your 'backwards compatibility' doesn't work and wordpad on vista no longer supports .doc.

We need to go after spammers not screw around with legitimate use of the internet.
Well in theory with ipv6 you could have a few million IPs to change to randomly, so running out wouldn't be an issue.
Good luck getting anyone to send email to you over ipv6 though.. we're probably 10-20 years away before it's practical.
They're thoughtless assholes with one goal in mind: to make a profit.
