Any time a single entry is dual homed, they have to go in lots of routers tables. Simple graph theory shows its going scale the same way as ipv4 just with a different size factor.
With the exception of the US (where bandwidth cheap), there are a limited number of ISPs in a position to allow smaller clients to dual home. This is true for most of the world with the exception of North America and thrid world countries.
I don't know of a single backbone carrier that couldn't cope with this plan if it were handed down by the IETF but none will push it because its too hard and will cut them out of exclusive contracts.
Besides IPV6 won't fix any of the problems with limited address space, it just makes the tables grow so large there will never be an efficent way to route (or even plan routes) and we will be stuck with the same problem but now we have 2x as much data it deal with.
The address space is running out because it is mismanaged.
The reason its mismanaged is a number of routers aren't doing their jobs correctly and the result of broken hardware design is that the minium allocations are huge.
I think that all new address space should be assigned to two ISPs at a time based on places where they regionaly overlap. This would allow me to go to sprint if they were my provider and get a/26 that is common to both them and someone say uunet in my region so they both can deal with the route as a/24 or so internally but one of them gets to aggregate it in a larger block and one of them won't.
This would allow millions of small compaines to proplery dual home. The current system won't let you do that unless you need a/20
As far as the load/memory on the servers is concerned, there are 16 million/24 blocks under thsi approach. If your router has 3 upstream interfaces and an internal network, that requires 2*2^24 bits or 4 meg of ram. Do it with contenta addressable ram (like cache tag ram) and you can run the biggest exchange point routers at speeds faster than the current approaches.
Why are the membership dues for the Asia Pascific Nic (APNic) in US$? The US$ has risen compared to every currency in the region so prices keep going up and up and up. The same is true for most of Europe as well.
it should be to discourage things like juice boxes
I figure the landfil costs of juice boxes is quite small compared to the long term health advantages of getting kids to drink something that might be good for them.
You can make money and still collect but you have to tell them how much you made and they deduct that from what they pay you and they may even use that income to figure your long term income level and adjust your paments down even more. Quite a few people used to get nailed by social security because they would stop working full time before they retired and their ss payments were based on the last 5 years wages. That can suck if you took 5 years to drop from full time to retired.
The black box will have a GPS reciver on it. It will most likely output NMEA streams which would be easy to simulate with a $10 board.
5 years ago a real GPS simulator (one that generates the Radio signals) cost US$50,000. Today they are less than $10k. The proposed toll rate and based on how much I used to drive in the US, a $10k box would save me 9000 gbp per year. If there is a economic case for me doing this, how many businesses will?
I've done this.... Its cost me a net block and I had to ask for a different address block:-(
To do this properly, you must have your own/24 at least and you must relay some spam because spamers will test for open relays before they do a database dump.
What you need to do is find out you have spam and then slow down the channel. There are lots of tricks to doing this. A 2 minute sleep between liens would be handy but you can't do this at the program level since the TCP/IP layer buffers and all you do is slow down your box. SMTP says that you can give several line answers by giving a number and a dash ("250-2.1.0 junk CR 250 2.1.0 sender ok"). You can send one line every second and keep the connection open for most real smtp servers. The best option is to tell the tcp stack to get nasty. Some tricks involve not acking most of the data, or tricking the far end to drop the MTU size to 68 or less:-).
If you crash the remote end, they will forget where they have spammed before and may hit your box again and again and again but its a spammer so how can you tell?
Since it set precedent, that means next time a judge is more likly to provide more conditions and more likly to award more money since the record comapny was already given a warning.
years ago when sharing data was very expensive (think 300 baud long distance dialup before AT&T broke up), a way was invented to share information at the cost of the people who use that info. It was called Usenet and it works very well. It still works well if you don't decide to carry all groups. The problem is that you need to have 5 news peers to make it worthwhile.
If you run your own server and want to peer, telnet news.abnormal.com nntp list active and see if any of the 700 groups are useful for you.
The number of C books is slightly more than there were 10 years ago. we have the classics of K&R C, The C answer book, The Unix programming env and a large number of other worthless titles. Compare that to Pascal books. There are now 3 at the local Borders. How about Ada, also less than 5 but a decade ago ranked more shelf space than java and C# combined. Most of the Java space has been reallocated to C#. To me that means its as trendy as the wrong color skirt at a fassion show.
I've been using Sun gear for a long time. I've got a real live working 12 year old sun sparcstation that still does its job and I use their new gear. I've played with the sun 10k as well so I'm not a stranger to their enviroment.
From what I've seen, Java sucks. That may be a result of me being an old C loving bastard but I don't expect to see the C++ for morons around in 10 years. If sun wants a language for programmers that need hand holding, they need a VB clone. hell, I've given then over a thousand workstations on a platter if they can can get someone to modify the yacc source in Kernighan&Pike's Unix programming enviroment to grok 85% of VB but they are stuck with Java. Well sorry suckers but in my local book stores, the amount of shelf space on Java books is heading down and thats a sign that the language has gone the way of Ada, Pascal and others. I figure Java books will be very hard to find in 5 years if not impossable.
One of the major supporters of Java at sun is Bill Joy. Keep in mind that this is the person that created the vi editor. The vi editor (which I use every day) is considered to be great work or insanly impossable to use. This can be proven by taking any random user and approaching them with the concepts behind vi. Based on those connections, what is Java's place in the world? It sure as hell isn't os class language and its not a language for amature programmers (because VB wins that one). So whats left? I expect AT&T's cyclone will out live Java. I know C and perl and fortran and cobol will.
Now Nokia had better get off it corporate ass and replace every system its using with non-ms stuff since it is a very bad business decision to have a critical part of your business completely in the hands of your largest competitor who has a track record of doing anything they can (legal or not) to crush their competition.
I heard there was a Finnish guy who wrote an OS they might want to consider.
How about the/. hero Dmitry Sklyarov, his company ElcomSoft makes bulkmailer and Advanced Email extractor as well as other tools to clean email address lists and localize them. His company has made lots of $$$$ selling spam tools.
Your almost right. Just skip the 128 bit cpus.
No application I run now needs 64 bits and none of them will run faster if they are compiled for 64 bits. The reasons for goig from 16 bits to 32 bits were quite strong--addressing was a real bitch. With the exception of a few small problem sets, we don't have that problem today. Moving around 64 bits when 32 will do results in the CPU doing more busy work and that results in less performance. A few things (almost always crypto or 2d graphics) could use a few nice 8192 bit registers but so far those aren't going into modern CPUs so I'm stuck using cryptocards.
I've been reading rec.aviation.student for a number of years.
One problem that all student pilots have is that they start overcontrolling the plane after about 10 hours. Most students are better at flying a modern (1960s?) airplane after 5 hours of instruction than at 10 hours. The reason is they try to compensate for every small dip. The planes dihedral will be doing the same adjsutments and the result is the plane goes the other way like any over controlled system. It can take another 10 hours to unlearn over controlling. I suspect that anyone with a 1/2 decent grasp of flying will over control the eary Wright flyers. Were the Wright brothers even controlling the plane or just along for the ride?
There is a nice landing strip near the Wright Brothers Memorial called First Flight. Just don't park there for more than 24 hours or a park ranger will give you a parking ticket.
In 1987 when I first got to play with a real 24 bit color system (a sparc 1!), I wrote a program that would display 1/12 of the colors at one time. It turns out that if you do this you quickly find that about 8 million of the 16 million colors appear brown. There are less than 250 colors that appear orange and when shown independently most people would describe at least 1/2 of thouse as brown.
My solution was to build a HSV->RGB analog converter and treat the 3 bit planes as H S or V.
The result is that you now have closer to 16 million useful colors.
Look into NTP. Its low level protocol is not about setting the time but finding out how far wrong the local clock is by using other clocks that aren't quite right either. Most versions of NTP know how to speed up or slow down the local clock to help bring it into the correct time. This only works for machines that are always on and in a enviroment with a stable temperature. Other time protocols are based on the concept that one clock is always right and there is a cascade of error.
All current versions of cisco IOS do NTP. If you have serveral routers, tell them all to do NTP. I tell all my boxes that their ntp server is their default router to make life easy. The problem is they will need a time source and you said you can't connect the net. If you have a big cisco router, you may be able to hook a GPS clock up to it. You could hook up another server that gets its time from GPS or WWV or dialing into the US navy or temporary connection to the net and using ntpdate. The routers will help smooth out the time jumps and the other server will keep the time within a second.
The serial NMEA sequences out of most GPS recivers are not very good and tend to cause NTP to drift. Motorola used to make a GPS reciver just for time but they no longer make it. If your looking at just using any GPS, the $160 Garmin GPS 17 can be mounted on a pole outside and has RS-232 out. If your more into raw electronic modules, their GPS 25 has a 1hz signal out.
I've got two solaris servers at work that I use ntpdate to force a time update using cron. One drifts 2 seconds a day and the other.5 seconds a day. A typical pc will drift about two minutes in a month.
Remember lighting likes antennas. GPS antennas tend to work better in out of the way places than WWV antennas. A GPS antenna will work with just a 45 degree cone view of the sky.
If you live next door, there is a good chance you can physicaly find them. If their business ethics cause you to lose business then there are things you can do. You can complain to your ISP. You can find a better ISP. You can complain to your local Better Business Bureau. You could even sue them in court depening on your location. You could get your good buddy Guido have a talk to them about their kneecaps. You have options.
That depends on how fast the names can be resovled. The reverse dns servers are way overloaded and when they have to deligate a few levels you will find one that is down. The result is not that the address doens't resolve but it times out. Make sure your filter can tell the difference.
