Yea postfix is great if your not running uucp, fax gateways and the like. (yea I'm sure there may be solutions for postfix to do those things but it's not exactly out of the box if you have been doing them with sendmail for years they just work) I'm not sendmails greatest fanboy but once you get over the learning curve it just works postfix provided no functionality that sendmail dosent that I require as yet. Maybe when one of these new smtp antispam changes catches on and dosent support sendmail I'll change. But thats not likly to happen soon.

Nope learned it loved it and if you want a nice GUI buy it. Will people never learn if they want a nice happy easy sendmail you can buy it. The guys that write it sell a nice administration front end. It even handles multiple instances on various boxen so it scales ok to enterprise and ISP settings. Why does everybody bitch that sendmail is hard to setup does everybody just dred the idea of forking out a hundred bucks for a nice front end to a mail server thats been around the block and is about as defacto a standard as they come?
OK I may just be jaded because sendmail has gotten me though some tough times and nasty issues at a time when uucp was still common.
Good for you I agree that small NAT boxes are a good thing as the offer some protection. I am just stateing that PPPoE is a bad idea it has drawbacks. There are no advantages to it and while the drawbacks are not that major why use a flawed system when you dont have to?
At minimum PPPoE has a smaller MTU than ethernet so your incuring more overhead in sending packets. It also requires a ppp stack to be running rather than just having the ethernet jack work. Yes now everything is used to working with PPPoE but it dosent mean it's not a hack or efficient.
I think that price is an agree to disagree thing I think $1m is very expensive when you considers it's going to take hundreds of meters to wire a small home. Course there is nothing saying you couldent run 240v DC and get a good deal of wattage. It's all about whats about right so your not up and down converting everyplace.
These are places that do go nealy all DC it's mostly in the solar powered homes all DC lights etc etc etc I think 12v is the defato standard because of the auto industry but they are looking to migrate to a higher voltage last I heard (thats rumor as far as I can tell but it does make sence as it would mean smaller lighter wiring harneses)
Right now I think it would make more sence to add a cooling jack to the house internals. All sorts of things are comming with fans and putting out lots of heat it would seem to make sence to start centralizeing the disposal of that waste heat and possibly making it do something usefull like heat water for bathing.
Do you relize the size and cost of copper cable that you would have to run around the house to provide decent wattage? Besides if you going to do something like that why not bit the bullet and run power over ethernet and kill 2 birds with one stone. You would have gigabit eithernet and enough wattage to run a lot of smaller devices (12 watts and change on cisco if memory serves) I say thing because running DC power in a daisy change to outlets would require some beefy cable at 12 volts as in you need ten times the amperage ish vs your current AC.
I do agree that 240 would be a better power standard I run my computers and racks on it. But again it's maily because you can get 2 times the wattage on the same wire.
While I agree hurting IBM's reputation isn't worth borhting as they sold of hard drvies anyway. Class action suits do take a lot of time and effort but it would seem the leeches are getting a lot more than fair compnesation for there work. Yes I relize it's a gamble as they dont get anything if they loose either. If they dont feel they have a strong enough case to win they should not be getting into a class action suit and removing the rights of thers to sue individualy.
OK I have allways wondered why companies that dont want there drivers to be open dont do the same thing they used to do for other UNIX boxes and release those stripped code files the ones that been through the preproc and are pretty damn unreadable (about the same as the output of a decompiler)
But to USB didn't they spec out of whole bunch of ways to communicate just so drivers should not have to be written? The hardware is supposed to work to the USB networking device so it can plug and play into anything?
Converting a subway car or bus to be a faraday cage would seem simple as insuring a good conection between body panels and using some metalacized(sp) glass and again insureing a good eletrical connection.
Granted I think Busses subways etc are the perfect place to use cell phones as your not driving and there is no content people want to hear. That being said some people still dont know how to hold a conversation quietly. There are people that understand you dont need to yell at the cell phone or even speak in a normal speaking voice to be heard at the other end. I wonder would it be that hard to convert a military style lash mic (the ones that allow you to subvocalize and thus make barely any noise at all) for use on a phone hands free. Tack on bluetooth and a earpeice and you can chat all day without disturbing people.
It's not legal to activly jam Cell phones because your not supposed to be broadcasting on that piece of spectrum. Now anybody that has ever had eletronics 101 should remember a faraday cage and how easy they are to build but let me elaborate:
Your a Movie Theater and you dont want cell phones or other wireless devices to work so as to not have people gabbing on them during the movie.
When you build or do any extensive renovation your prbably going to use a lot of drywall if you install a few layers of chicken fence or other suitable fine grid or wire. Make sure the doors are metal (fire code I would think) and that they maintain a good contact to the grid etc etc etc. When the doors are closed yours not going to see an increadable ammount of attenuation to any RF signals with a wavelength longer than the mesh pitch and a good attenuation to most everything else.
Now you have a movie theater that cell phones dont work in. It would be nice if we could clasify transmision types say via bluetooth since thats a hot new thing on cell phones and have the possibility to ask the phone to switch to silent mode while not affecting paging functions for doctors and other on call critical people that can be assumed to be more responcible than a 15 year old with and "emergency" call.
It's realy not that hard to do. Step A get a cell on the same carrier and account, swap numbers change billing info your done. I have done this with Nextel to keep my number when moving off a corp account to a personal one. The Corp did end up with a new number but it wasent on contract (that stayed with the phone) so they were free to cancel it. It's generaly realy easy to swap numbers on phone on the same account as well as move a single phone to another account with it's number. Course this may just be Nextel they are used to deeling with business more than personal it seems at least to me.
To Linux a virtual interface is a real interface to the network it's not. You cant have two DHCP servers running as the broadcast domains overlap. So say if you have a cable modem that runs DHCP sometimes you will get an address straight from your provider sometimes from your range. Your provider will have access to yur network if they choose to as well. To be secure you would need to use a tagged virtual interface. Linux does support this but the switch to do this in general are expensive as they are managed. I understood the type of interface you sugested under linux but you seem to lack understanding on how things below IP work.
He said firewall while most people realy dont understand what a real modern firewall does anymore a virtual interface is nearly useless for any sort of firewalling. A tagged port would be fine.
If you use a virtual interface you may not be able to run DHCP if the ISP does as well and have it work well. Running a PPPoE session might work ok if you trust your ISP.
Again I should stress natting does not make a firewall. You need a lot of proxy applications that can filter at higher levels than IPs ports and who initiated a connection. A firewall is somethough that should be able to filter out just about anything you wont want getting into your network. Now some people just dont care like most home users.
I would say the same thing about calling a linux box a router it can route yes it's ok at it yes but it's latency is horid. Again for home use it's ok but PC's cant even fill a gigabit nic without incuring massive latency forget a gamecube.

Or remember eletronics pre 80's when things prosumer and above kit came with owners manuals that allowed you to field strip and repair the unit if need be? I'm thinking of those manuals that came with complete circut diagrams with all parts labled and a nice component list. This whay when something blew it was a 30 minute saturday project.
The more important distinction is I'm the owner not the user it's my gear I baught and paid for it. Someday we will get decent laws that make software a product not some vaporous IP that you only get a liscence to use at least for embeded stuff. And no I dont think it's should be required to incluse source code but I think I should be able to do anything with the binary sans giving it to other people.
Not much infomation in the article but I must admit it would be nice to start having SAN/Cluster filesystems as part of stock kernels. People realy dont understand the power of these filesystems to provide security and scaleability. With modern cluters inconnects being able to serve up fiber channel multigigabit ethernet and low latency interconnects it gets easier and easier to make pure diskless compute nodes that are for more than just number chrunching.
Think about only needing a single copy of your web server image mounted read only to the web servers themselves.
Setting up CAD farms that all utilize direct attached storage in a shared method leaving network bottlenecks behind.
Low end systems like firewire may even be able to attach single disks between multiple machines with similtanious access (have to check on multi initiator firewire looks posible never seen a definate though) in a safe manner.
Ok just one word Bluetooth plugging things into phones etc is a PITA. Bluetooth isnt nessicarly the end all be all but it's coming to be current tech for low bandwith low poper cord replacement.
It's more like I wonder if he will ever get back anything that was on the list forget about things off the list. US laws are horid since the 80's about getting any ammount of respect from the law guess thats what happens when you declare war on your populace.
There is athe even better external system on light passanger rail called turn off the power ok we now have a train full of hostanges that arent going anywhere. No better or worse than any other building. Oh yea in general it's elevated with lots of windows so the sharp shooters can pick them off easier.
Thats per layer right now writeables are single layer but pressed disks can have multiple layers. So for a 2 layer disk (I think thats the current max) it's 60 gigs vs 32 just about the same as the 8 gigs and change of a DVD now vs the 4.7 gigs recordables.
Um you havent looked at nature to much the greed is rather prevalent. Watch a wild animal defend it's food and be a glutton. Yes some animals share within the community generaly with a defind pecking order that gets established through violence. Same goes for teritory. Sin has nothing to do with nature thats just an artificial part of your beleife system. Animals dont seem to regret what they have done they either survive or they dont.
Firewire can run isochronous data as well as async. I think your issues with shoutcast etc is more in the PC side thats not a real time envornment and loves to buffer data that is setting all the streams a bit askew from each other. Even the audio cards in PC's have different delays in them. For that application I use ethernet to audio converters (there are several on the web including build your own) look for ones that use a server in multicast mode there shouldent be any noticable delay that way (the difference between devices should stay under a few ms from switching delays)
But that would involve work only detectives get to do work your normal police get stuck doing this garbage. If they would concentrate on enforcing laws as in going after violent and property crime rather than trying to tax the populace through fines we migh actualy get crime rates down. Generaly speaking the car chases dont do any good the govenor in my state actual orded thaey be cut off after 80 to keep inocent victims down after all most of the time they know the vehical or can track it via helicopter till they stop then send in swat to make the arrest. Car chases just endanger peoples lives but they are fun for the officers involved it would seem.
I think your difference is going ot be how many accidents they get into dosent matter whose fault as we all know you can avoid accidents just accidents period. It's the tickets rasing rates that gets me realy it's just another selective tax on peoples time. Now remember I said driving at a safe but above limit speed not the idiot in a honda with a folgers can for a exaust tip splitting lanes and going 100 through a city. I live in a 65 mph top speed state I worded at the DOT in the state and they designed the roads for 75 mph for a semi with bias ply tires so 80 on dry pavement outside of congestion should be by design safe.
BTW I have only been involved in 2 accidents involving other people each were under 10 mph bumper dings and over 10 years ago I have been driving for 12 years.
