Yes, kids, faux focus-group approved patriotism is selling out. The same focus-group think is the reason they DELETED the trade center from the movie.

Why does this impact the printer company? Because the same cheapskate who won't buy another cartridge then sees the shitty print quality, and calls them demanding a new cartridge... Quite often, if under warantee, they end up getting one. Good luck proving someone refilled theirs.

Secondly, M$ should be bearing the brunt of this.

Yay.
Anyway, this dosn't impact me, aside from the occasional mailing list I shutdown. It's amusing to watch the entire winderz world fall off the net. Again. And again.
Perhaps if some of these dipshits would hit M$ with a class-action suit for gross negligence there'd be changes. As far as I'm concerned, there ARE NO OUTLOOK VIRUSES. They're simply using the system exactly as designed.
Actually, for the clue impaired, this happened
because of those other continent's having really
ass-backwards telco laws.
It was generally cheaper to drop a line to the US and back then to cross state lines pre-EU. All
the traffic on those lines came from one european
country and back to another. So no, don't expect
_US_ to subsidize your stupid political bullshit pricing structure.
I'll also note that UUnet is _GLOBAL_. You can't be _GLOBAL_ without existing in places other then the US. Therefore, to connect to UUnet you do not need to drop long-haul undersea cables. There's another point oft forgotten. Again, micro-monopoly telco rates drive your prices up, not "The evil american conspiracy". We've got 50 independant states and we manage to keep our in-US bandwidth cheap.
I'll also posit that there's very little offshore content that wants to be browsed, whereas US ISPs that get breaks (AOL/Earthlink) are huge destinations for tens of millions of viewers. And, of course, overseas companies that want cheap
hosting worldwide go where it's cheapest for the entire world to see. Silicon valley, or some Texas data warehouses now.
If you can get all your companies to not-offshore all their content, perhaps some traffic would flow in that direction, and you could say "Wah! If you don't give us a good rate we'll take our ball and go home!" At this point, nobody wants your ball. Make them want your ball, and you'll get somewhere. Whine a lot, and you'll keep paying like _EVERYBODY ELSE IN THE FUCKING WORLD_
Wah! I'm bearing the full cost of providing access and content! Even though big, bad global backbones
are profiting because their other customers are
getting access to my oh-so-kawii sites, I have to pay anyway!
The phrase "Cry me a fucking river" seems to apply.

However, it's also accurate to note that Orlando, Florida ISPs still have to pay 12-1500/month for a T1 to any of the "Big 3", just like everyone else.

(P.S. Yes, at a certain point you get discounts due to what you're bringing to the table. If an Earthlink/AOL sized african ISP can't get a discount, they need to behead their IT people and hire ones that can negotiate beter)
I don't want to call you a liar, but if indeed this is true then you are an EXTREMELY rare case. Indeed, as a professional software developer I find this hard to believe : I find it difficult and time consuming to understand my own code 3 days after I've written it, so I find it incredibly hard to believe that someone can jump into any of the open source code, most of which could best be described as spaghetti code of complex relationships and undocumented correlations, and just "fix up something" (without a MASSIVE investment of time). Could you tell me an instance where you had a problem and went in the code and fixed it?
I do all the time. Usually not kernel-level but I've fixed and submitted many a patch for system binaries.
Generally I just "use the source" when an obscure feature dosn't work the way I expect, generally to find it's a simple recompile-with-a-#DEFINE set to fix. (mount -o noatime before mount had that option). Sometimes it's more complex (INN, apache, bind) and sometimes it's downright hideous (the ident deadlock on postgres 6.X)
At least once having the source would have helped a LOT. (Oracle using a case-sensitive match in one place, and insensitive everywhere else. UGH)
Pre-rebuttal for the obvious argument: Don't say "Only the kernel!" because windows isn't "Just a kernel", it's the full suite of tools that goes with it.

...Since many of the latest distributions (like RH7.2 and MDK-8.1) offer journalized FSs (ext3 by default even), shred will fail. RAIDs will fail too.
Reiserfs, ext3, etc are all metadata-journaled filesystems, so overwriting a block will hit the
same block as you were on before.
As for RAID, the data is toast unless you have a dead drive. If you have a dead drive, degauss it before RMAing it (if you're paranoid)
A RAID array HAS to write to every disk in order to be redundant. It just dosn't read from them all at all times.
Networked filesystems have to be nuked at the source, yes. Compressed filesystems are their own bit of fun.
And reiserFS can use that slack space for multiple file 'tails', although I don't believe it's on by default.
As someone who's been on the net since '94, I get

Somebody give me a reason to help the development effort!
Because someone like you won't let them do something stupid like store files uploaded at your node in plaintext before encrypting them... and _LEAVE_ them in the datastore plaintext, forgotten, just waiting for someone to come and find them.
Or how about not creating temporary files for large uploads? Would you do that? Would you just tell someone to 'delete them' afterwards, or would you go through and overwrite the contents with random data first?
Perhaps you would be able to create a block storage system with the simple requirement of storing files sized in powers-of-two that won't continually decide to eat it's own contents.
Then again, you might choose to implement speed-critical things like cyphers in a machine-native language (C), so the whole project will run at a reasonable speed.
Perhaps you might be inspired to write the WHOLE thing in a machine native language (C) and spend
(gasp) 25 minutes writing some wrappers around
the few OS-dependant things it has to do (Network sockets, mostly. Opening files is pretty standard)
No, someone like you better stay off the project,

Some of us have higher standards for our connectivity.
Force advertisers to submit a normal sized one as well, and let us pay to cut the ad down to the current size. I really do NOT mind/. the way it is now, but if you bow to advertisers now, it'll go to popups, popunders, spawners, homepage redirectors and all the other B$ you get if you missclick on google.
I'd be willing to pay to see the (somtimes very entertaining) ads you have now... because it's nearly the only site I've been to where I've been interested enough in an ad-banner to click on it.
However, I have very little hope of the survival of/.. If it survives because people pay, you won't have enough non-paying viewers to make the ad-banners worthwhile. If you get money from ad-revenue, the people paying are going to realize that forcing ever-larger and more obnoxious ads down the throat of geeks results in more filtering and less clickthroughs... and pull the plug.
You could just throttle the free, add-server version to a few meg/sec and let premium viewers have 1kpages/$ on a non-throttled server. That
would encourage both payment _AND_ people using various methods to reduce the load on your server. Cache.net anyone?
"Major Canadian broadband provider plans to charge heavy users higher monthly access fees as high as $80 per month. Read the article here from the Globe and Mail. If only the world would protest. What's the point of high speed broadband access if you can't use it to full potential without having to start selling organs to pay the bills?"
Er, Wah some more. No, seriously, cry me a river.
$80 canadian... that's what, two burgers and a biggie fry?
Canuck jokes aside, $80/month is quite reasonable
for high speed bandwidth. Consumers are asking content providers (and ISPS) to bend over and take it without any lube. My personal bandwidth costs are probably in the $500/month range. Who am I paying for? You. Why are your costs going up? Because every dammed broadband provider went under, thats why. It costs money to give every warez kiddy/napster-weenie those 150k/sec downloads they love to brag about. Where'd that money come from? Hint: It didn't. 'casual' users never bothered switching over to broadband, POTS works fine for checking your email once per week. So, the usage-ratio goes right out the window.
At current prices, DSL providers need to oversell their bandwidth about 1000:1, since the telco takes most of your bill. Cable is a little better, since they own their own lines... they can probably get away with 250:1.
If you want real broadband, go flip on your TV. It's free!... and is starting to have less ads then the internet.
I just want to firewall ports around 6667 to keep people from getting in IRC wars
Seriously though, I could care less about the proliferation of DoS/DDoS tools. What bothers me is that the ISPs where this crap is coming from have never been blackholed by the rest of the community. It's not THAT hard to implement a widespread policy of filtering source packets, and
that cuts down on a LOT of the methods used by the skript kiddiez.
The pathetic part about it all is it was already
a problem in '95, and source-filtering was strongly recommended then. Soon after, no ip directed broadcast became also strongly recommended. Sadly, I can still get a 250:1 return on a forged ICMP ping (thankfully, their outgoing bandwidth is only a T1)
The real culprits are the people too lazy or inept to be allowed to run a network.
... just use earthlink's mailserver, that's what it's there for. And thank that you didn't get stuck with AOL, since they force you to use an @aol.com email address.
Seriously, this is a Good Thing(tm). I know NOC guys at Earthlink/Mindspring, they keep on top of their servers. (Although I've got better overall uptime on mine. Hah!) So there's really no need to use foreign SMTP servers.
Aside from that, as a seperate ISP, I BLOCKED Earthlink dialups from directly contacting port 25 here long before they put the filter in place. It's neigh-impossible to police the 6 or 10 million accounts they have right now for spammers... much easier to put heuristics on the mail gateways watching for spam-levels of mail going from one dialup. Effective, too. They're not my #1 source of spam.
Also, it's not just earthlink. A lot of their POPs are partnered with port-resellers. The major resellers automatically put a port-25 block on, and punch a hole back to the ISPs mailserver. There's nothing Earthlink can do about it. I have Qwest as a port-provider on our national dialup, and they do that for us as well.
In summary, after 2000, any ISP that provides clear access to port-25 outside their network is no longer a techie-friendly ISP, they're spammer-friendly and techie-hostile.
Loss #1: The comparason to "FTP".
Had they said 'HTTP' people would realize, "Oh yea,
I download stuff off the web all the time, works fine here. Why should I spend 150 grand?" It's a pure PR trick. They're talking about ACK delays with high-latency TCP links. The problem is better solved with a modern TCP stack at both ends (I.E. put an active TCP proxy at both ends, or even at the sending end, and your traffic flows much better)
Loss #2: "we don't require data to be acknowledged" ... translates to "If your machine crashes, we'll just keep sending UDP packets forever. So it _DOES_ need to be acknowledged, they just don't admit it because it sounds cooler.
Loss #3:"Transforms the data into a recepie..." ... much the same way gzip does. Or perhaps they're talking more like raid5 equasions on your data. Either way, they're spending a LOT of CPU power on a non-solution.
Loss #4: Lack of feedback on net conditions along
your path leads to overall slower delivery. Yes,
amazing as it may seem sending data faster means it gets there slower. The net is a series of leaky pipes... build up too much pressure and packets escape (get dropped) Simply blasting UDP packets at the destination tends to waste a LOT of bandwidth, and more then likely will take longer then having them simply hit a URL and download it.
Loss #5: michael, for posting this without having
any clue. News for Nerds, stuff that matters. One tends to wish the people POSTING IT actually had any idea what these strange words (like FTP, UDP, TCP) mean.
However, 2 per room is not enough. There are a number of reasons for this
They're never where you want them.

Once you've got the cables in, you'll see more uses.
... and you always will. Thats why god gave us an amazing bit of technology called a "Switch". What, you're really going to use 10gig to every station all the time? Riigghht.
When building, it's cheap
... except when you have to get it past the inspectors. You DO have low-voltage certification in your state, don't you? And don't forget how cheap plenum is as opposed to normal cat5... on the order of what, 65c/foot for plenum compared to 5c/foot normal in the bulk you'd be buying for a house?
Huge SARCASM warning, for those who don't get it.
There's lots of expenses involved in cabling while-building. Secondly, don't even THINK about
following the phone lines. They're done ultra-cheap, daisy-chained throughout the house.
No, you cannot daisy-chain ethernet, and do you really want to run a token-ring or FDDI/CDDI? Didn't think so.
If you _REALLY_ want to do it right, install (empty) wall boxes, attached to metal conduit going either up to the attic or down to the basement cieling, with nylon cords in them to pull things through later. Then you can use the technology-de-jour or add those extra Cat-9 12-pair wires that you just HAVE to have 5 years from now.
As for fiber/copper, there's 1gig copper now. Been out for years, in fact. Networld+Interop 99 in atlanta had it running over barbed-wire fencing, which was funny as hell.
You probably won't need more then 2 locations per room, but try to place them intelligently... having cords strung everywhere is always ugly.
Computers require power (Yea, duh, but you'd be surprised how many people don't plan for this) so put your drops near the power outlet. You can
always run VoIP internal to your house, so no need
for phone-lines everywhere.
As for what to run initially, Fiber to the Desktop is Bad (tm). The first time you push your computer back against the wall is when you realize
exactly how big a mistake it is. Fiber between switches is a good idea, since fiber bandwidth
is generally 10x copper at any given point in time, and is also way above what any PC needs.
Fiber DOES let you have a SAN, though (Storage Area Network) and there is some support in linux
for distributed/shared disks/filesystems. (Not stock, search for GFS patches... possibly getting old now) A nice scalable SAN is great fun,
plug another FC drive in the tower and every machine in the house gets an extra 36gig.
Get a DVD jukebox with a few drives and anyone
can watch DVDs from anywhere, all at once.
DVD is VBR, average 4.5Mbps (Generally) The
spec allows for rates as high as 10Mbps, but anything higher then that will not work on older
players. So, don't plan on needing more then around 10Mbps for DVD video
As for HDTV, it would be quite stupid to run it uncompressed, since that's around 1.5Gbps. HDTV broadcasts are bandwidth-limited to 19.3Mbps, so
use that.

(P.S. Yes, at a certain point you get discounts due to what you're bringing to the table. If an Earthlink/AOL sized african ISP can't get a discount, they need to behead their IT people and hire ones that can negotiate beter)
I do all the time. Usually not kernel-level but I've fixed and submitted many a patch for system binaries.
Generally I just "use the source" when an obscure feature dosn't work the way I expect, generally to find it's a simple recompile-with-a-#DEFINE set to fix. (mount -o noatime before mount had that option). Sometimes it's more complex (INN, apache, bind) and sometimes it's downright hideous (the ident deadlock on postgres 6.X)
At least once having the source would have helped a LOT. (Oracle using a case-sensitive match in one place, and insensitive everywhere else. UGH)
Pre-rebuttal for the obvious argument: Don't say "Only the kernel!" because windows isn't "Just a kernel", it's the full suite of tools that goes with it.

Perhaps if you READ THE DOCUMENTATION you wouldn't be posting to slashdot like an AOL user.

Reiserfs, ext3, etc are all metadata-journaled filesystems, so overwriting a block will hit the same block as you were on before.
As for RAID, the data is toast unless you have a dead drive. If you have a dead drive, degauss it before RMAing it (if you're paranoid) A RAID array HAS to write to every disk in order to be redundant. It just dosn't read from them all at all times.
Networked filesystems have to be nuked at the source, yes. Compressed filesystems are their own bit of fun.
And reiserFS can use that slack space for multiple file 'tails', although I don't believe it's on by default.

Yes, you got him. Linus Torvalds, the sole resident of the entire country of finland, is posting on /.
I see the clue-level hasn't changed much due to subscription...
--DanAs someone who's been on the net since '94, I get over 50x as much spam as valid email.
So, hit "delete" 50 times, read one mail, delete another 50 times...
Please, do me a favor and call me on it. I'll have my spamfilters forward to you through the list of open-relays that I've got blocked. I'll even be nice and only send you each message ONCE rather then the 5-6 times I get it.
My spambox gets more traffic then the linux-kernel list. I'd be happy to share.

Because someone like you won't let them do something stupid like store files uploaded at your node in plaintext before encrypting them... and _LEAVE_ them in the datastore plaintext, forgotten, just waiting for someone to come and find them.
Or how about not creating temporary files for large uploads? Would you do that? Would you just tell someone to 'delete them' afterwards, or would you go through and overwrite the contents with random data first?
Perhaps you would be able to create a block storage system with the simple requirement of storing files sized in powers-of-two that won't continually decide to eat it's own contents.
Then again, you might choose to implement speed-critical things like cyphers in a machine-native language (C), so the whole project will run at a reasonable speed.
Perhaps you might be inspired to write the WHOLE thing in a machine native language (C) and spend (gasp) 25 minutes writing some wrappers around the few OS-dependant things it has to do (Network sockets, mostly. Opening files is pretty standard)
No, someone like you better stay off the project, god forbid it be usable by now!

Actually, I don't use a MoDem, I use a CSU/DSU (T1) at home, and T3 at work.
Some of us have higher standards for our connectivity.

I'd be willing to pay to see the (somtimes very entertaining) ads you have now... because it's nearly the only site I've been to where I've been interested enough in an ad-banner to click on it.
However, I have very little hope of the survival of /.. If it survives because people pay, you won't have enough non-paying viewers to make the ad-banners worthwhile. If you get money from ad-revenue, the people paying are going to realize that forcing ever-larger and more obnoxious ads down the throat of geeks results in more filtering and less clickthroughs... and pull the plug.
You could just throttle the free, add-server version to a few meg/sec and let premium viewers have 1kpages/$ on a non-throttled server. That would encourage both payment _AND_ people using various methods to reduce the load on your server. Cache.net anyone?

Er, Wah some more. No, seriously, cry me a river. $80 canadian... that's what, two burgers and a biggie fry?
Canuck jokes aside, $80/month is quite reasonable for high speed bandwidth. Consumers are asking content providers (and ISPS) to bend over and take it without any lube. My personal bandwidth costs are probably in the $500/month range. Who am I paying for? You. Why are your costs going up? Because every dammed broadband provider went under, thats why. It costs money to give every warez kiddy/napster-weenie those 150k/sec downloads they love to brag about. Where'd that money come from? Hint: It didn't. 'casual' users never bothered switching over to broadband, POTS works fine for checking your email once per week. So, the usage-ratio goes right out the window.
At current prices, DSL providers need to oversell their bandwidth about 1000:1, since the telco takes most of your bill. Cable is a little better, since they own their own lines... they can probably get away with 250:1.
If you want real broadband, go flip on your TV. It's free!... and is starting to have less ads then the internet.
--Dan
Seriously though, I could care less about the proliferation of DoS/DDoS tools. What bothers me is that the ISPs where this crap is coming from have never been blackholed by the rest of the community. It's not THAT hard to implement a widespread policy of filtering source packets, and that cuts down on a LOT of the methods used by the skript kiddiez.
The pathetic part about it all is it was already a problem in '95, and source-filtering was strongly recommended then. Soon after, no ip directed broadcast became also strongly recommended. Sadly, I can still get a 250:1 return on a forged ICMP ping (thankfully, their outgoing bandwidth is only a T1)
The real culprits are the people too lazy or inept to be allowed to run a network.

Seriously, this is a Good Thing(tm). I know NOC guys at Earthlink/Mindspring, they keep on top of their servers. (Although I've got better overall uptime on mine. Hah!) So there's really no need to use foreign SMTP servers.
Aside from that, as a seperate ISP, I BLOCKED Earthlink dialups from directly contacting port 25 here long before they put the filter in place. It's neigh-impossible to police the 6 or 10 million accounts they have right now for spammers... much easier to put heuristics on the mail gateways watching for spam-levels of mail going from one dialup. Effective, too. They're not my #1 source of spam.
Also, it's not just earthlink. A lot of their POPs are partnered with port-resellers. The major resellers automatically put a port-25 block on, and punch a hole back to the ISPs mailserver. There's nothing Earthlink can do about it. I have Qwest as a port-provider on our national dialup, and they do that for us as well.
In summary, after 2000, any ISP that provides clear access to port-25 outside their network is no longer a techie-friendly ISP, they're spammer-friendly and techie-hostile.

Loss #1: The comparason to "FTP".
Had they said 'HTTP' people would realize, "Oh yea, I download stuff off the web all the time, works fine here. Why should I spend 150 grand?" It's a pure PR trick. They're talking about ACK delays with high-latency TCP links. The problem is better solved with a modern TCP stack at both ends (I.E. put an active TCP proxy at both ends, or even at the sending end, and your traffic flows much better)
Loss #2: "we don't require data to be acknowledged"
... translates to "If your machine crashes, we'll just keep sending UDP packets forever. So it _DOES_ need to be acknowledged, they just don't admit it because it sounds cooler.
Loss #3:"Transforms the data into a recepie..."
... much the same way gzip does. Or perhaps they're talking more like raid5 equasions on your data. Either way, they're spending a LOT of CPU power on a non-solution.
Loss #4: Lack of feedback on net conditions along your path leads to overall slower delivery.
Yes, amazing as it may seem sending data faster means it gets there slower. The net is a series of leaky pipes... build up too much pressure and packets escape (get dropped) Simply blasting UDP packets at the destination tends to waste a LOT of bandwidth, and more then likely will take longer then having them simply hit a URL and download it.
Loss #5: michael, for posting this without having any clue.
News for Nerds, stuff that matters. One tends to wish the people POSTING IT actually had any idea what these strange words (like FTP, UDP, TCP) mean.

However, 2 per room is not enough. There are a number of reasons for this
They're never where you want them.
Once you've got the cables in, you'll see more uses.
When building, it's cheap
Huge SARCASM warning, for those who don't get it.
There's lots of expenses involved in cabling while-building. Secondly, don't even THINK about following the phone lines. They're done ultra-cheap, daisy-chained throughout the house. No, you cannot daisy-chain ethernet, and do you really want to run a token-ring or FDDI/CDDI? Didn't think so.
If you _REALLY_ want to do it right, install (empty) wall boxes, attached to metal conduit going either up to the attic or down to the basement cieling, with nylon cords in them to pull things through later. Then you can use the technology-de-jour or add those extra Cat-9 12-pair wires that you just HAVE to have 5 years from now.
As for fiber/copper, there's 1gig copper now. Been out for years, in fact. Networld+Interop 99 in atlanta had it running over barbed-wire fencing, which was funny as hell.
You probably won't need more then 2 locations per room, but try to place them intelligently... having cords strung everywhere is always ugly.
Computers require power (Yea, duh, but you'd be surprised how many people don't plan for this) so put your drops near the power outlet. You can always run VoIP internal to your house, so no need for phone-lines everywhere.
As for what to run initially, Fiber to the Desktop is Bad (tm). The first time you push your computer back against the wall is when you realize exactly how big a mistake it is. Fiber between switches is a good idea, since fiber bandwidth is generally 10x copper at any given point in time, and is also way above what any PC needs.
Fiber DOES let you have a SAN, though (Storage Area Network) and there is some support in linux for distributed/shared disks/filesystems. (Not stock, search for GFS patches... possibly getting old now) A nice scalable SAN is great fun, plug another FC drive in the tower and every machine in the house gets an extra 36gig. Get a DVD jukebox with a few drives and anyone can watch DVDs from anywhere, all at once.
DVD is VBR, average 4.5Mbps (Generally) The spec allows for rates as high as 10Mbps, but anything higher then that will not work on older players. So, don't plan on needing more then around 10Mbps for DVD video
As for HDTV, it would be quite stupid to run it uncompressed, since that's around 1.5Gbps. HDTV broadcasts are bandwidth-limited to 19.3Mbps, so use that.
