Ah, here the leaves cause traction problems. They solve it using a special compound (gel with sand mixture) applied to the tracks by some of the trains.
Snow is mainly a problem for the points, here. So they are fitted with heating, which fails sometimes.
That sure sounds like a dumb system. The trains here have had automatic doors for many years, but they are simply controlled by the driver. Train stops, driver releases the doors, from that time the passengers can press a button and the doors will slide open (they remain shut when nobody presses the button or when the button is pressed when the driver has not enabled it). There is also a button to close the door, but rarely anyone pushes it. When the train is ready to depart, the conductor uses a key to close all doors except the one where the key is inserted. He looks if all doors have closed and nobody is stuck, then releases the key to shut the last door.
This system existed way before GPS. (indeed there were manual doors on older trains where you could open the door during the trip and all doors had to be closed manually)
Hey that is interesting, Dutch Rail uses the same excuses... maybe they copied them?
I always found it interesting that a railway company claims "the tracks are slippery". It is their business, they claim it is a good idea to put iron wheels on iron tracks to move tons of heavy iron all to transport a few people, and when there is a problem it is blaimed on the weather.
They should blame it on the design of their equipment. When I drive around in my car on tires with not enough profile, I get a ticket. The car must meet deceleration rates that their train cannot even approach, even under perfect weather conditions....
>The point being, a location is a point in time - may not be relevant 30 seconds later, travelling at 150km/hr.
Of course you not only send location but also speed and direction. And this could be improved by sending acceleration as well. Trains in normal service often adhere quite closely to predetermined speed over time (and thus location over time) curves. The GPS measurements only need to fix points on that curve and inform about deviations.
On a database server, you can install a quite small set of Linux packages, and keep it uptodate for only those packages. This will reduce the number of unpatched vulnerabilities.
On a Windows server, the first thing you need to install to download updates is Internet Explorer, and that also happens to be the source of the largest number of vulnerabilities on Windows (and is not counted in the 15). You also need many other things that you can omit on Linux, like the GUI.
But in previous discussions Brinkhorst has stated he will not vote against even if instructed so, because he considers loss of face more important than this case. (he has voted in favour before, then claiming it did not matter because it was not the final decision but only a decision to go ahead)

You would think it has plenty of trademark infringements, and associates the Microsoft name with an obvious scam. I expected them to shut down these domains quickly, but no.
I forward them the lottery scams that refer to domains registered on their "MSN Personal domains" service. They do not seem to care.
Interestingly enough, the names shifted from (variations on) cashchangeukltd.org, which is just the name of a fraudulent organization, to (variations on) ms-wordpromo.com, which could be seen as a trademark violation by their triggerhappy lawyers. You know, those that went after names like mikerowesoft.com because it was too much like a trademark they registered.
But despite several reports, nothing seems to happen. They just go on facilitating fraud, and even do so under their own trademarked names.
I start to believe that there is nothing more than a tracking number generator behind those reporting addresses, and the big Microsoft company is not interested in abuse of its trademarks.
What you have to understand is that the EU is not a government, a political institute that tries to balance the regulations in a country between freedom, justice, economic growth, and equal opportunities for people.
The EU is an ECONOMIC union. This has been deeply embedded within its history. The EU only focuses on international industry and economy, and it is completely indifferent to what happens to people and small companies.
As such, it pushes globalisation, it makes laws that enable multinational companies to do business in whatever country the like, and push out local initiative. All in the name of increased profit for the multinational company, and all without regard to the citizen.
There are many, many examples of this. The software patent stuff is just one of them, that may be the most visible on slashdot. But some of the participating countries had very well functioning government-initiated utilities (railroads, telcos, electricity companies, etc etc) that all had to be commercialized and opened "mandated by the EU" and in many cases it wasn't an improvement for the citizen. Of course the commercial companies and their shareholders profited, but the man on the street had to pay, and often lost a well-operating and simple system to a "freedom of choice" he did not ask for. (I really don't want "freedom to choose an electricity provider", what I want is a reliable service for a good price and no need to worry about what company is best).
Another example is the over-regulation of many activities and products, causing the costs for small companies to go way up and driving them out of business, again giving in to the large companies.
This year there will be referenda about new European laws, and without even knowing what these are about a large majority of the people has already stated they will vote against it. Maybe the laws are good, but most citizens just have had it with EU. Only the local politicians still are talking in favour of it (of course again with "it is good for the economy" talk)
What we need is scaling down, localizing activities, re-forming of communities and care about your fellow people, not globalization and multinational companies.
Even better! When this happens often enough, the ISP will seriously re-consider if they want to offer free or nearly-free webhosting to anonymous customers.
I still find it difficult to judge if something like this should be "in the kernel"... The description (and the many other ones by other people) all seem to suggest that the messages to be sent are quite high-level (application level), and the queuing times can be quite long. This suggests something like a mail transfer agent, that receives messages, attempts to deliver them, and keeps them on disk if immediate delivery is not successful. Not something you would do in the kernel.
On the other hand, kernels often include a message queue mechanism, to be used for things like inter-process communication or sending of data from a network stack to the user process. Those usually don't provide reliability beyond "the message will arrive as long as the system does not crash". That more seems like the domain for a kernel message queue system.
Of course a message queue that scales reasonably well (i.e. it can not only be used in a complicated network but also on a single machine, and it can be run in simple situations with simple configuration) would be very useful. It could be used as a base for anything between printer spooling and e-mail delivery. Maybe the long-awaited replacement for SMTP and LPD?
Radio amateurs have used this system for about 40 years. It is called "QTH Locator" or just "Locator". (QTH is the International Morse-code abbreviation of "my location is...")
It first it was a European system, but it later has been modified for worldwide coverage. Longitudes and lattitudes are converted to letters and numbers, alternating between longitude and lattitude and between base-30 and base-10, so that a limited syntactical check can be made (if you miss one character you'll notice the letter in a place where a digit should be, or vice-versa)
The more characters you send, the more precise your location is specified. For example, I could specify my location as "JO" which specifies the northwestern part of Europe, or "JO22" which specifies about the size of a province, or "JO22MC" which specifies the area of a small city, etc.
Of course this system was not patented. Nobody would think of patenting such a system. But at least it exists as prior art.
Maybe it will start them thinking about a better protocol than SMTP? They can investigate the history of SMTP, its assumptions w.r.t. mutual trust, where that went wrong, and how a new protocol should be designed so that it is not so easy anymore to hide the origin of mail.
In a perfect world mail servers would drop win32 executables automatically, but this is not widespread policy.
Any idea why? For more than 5 years (since happy99.exe was mailed around) we have been blocking all executables on the mailserver at work, and it has rarely caused any problem. In those years it sometimes happened users mailed "funny stuff" around that was made as a self-running flash animation, but this has all been replaced by powerpoint slideshows now. Apparently everyone now has a (pirate) copy of Office so the flash is no longer needed.
But this filter has blocked "new" viruses many times! I trust such a generic filter much more than a virus scanner, which always detects after-the-fact.
There is rarely any need to send a program via mail. When it is required for a software update, we have a special mail address where it can be sent and evaluated by hopefully more knowledgable people.
This was decided some time ago when there were so many patches that people started to notice how leaky the system is, and wondered why they had to go to Windows Update once or twice every week.
And after all that, the part of the world that the USA now calls "evil" will be in the position to look down and judge what the highly acclaimed "freedom" is really worth.
But unfortunately the "free" Americans don't realize that and vote for Bush even now that they still have a choice.
You have misunderstood the situation, as has been explained to you in other responses. There is no problem with end-users not wanting to trust you.
Of course it may be that the MPAA or RIAA does not trust your system and their members do not want to send you protected content, risking that you decrypt it and publish the plain unencrypted version. And they are probably right about that. But that does not mean anything for a trust relation between you and your customers or the users of your open-source program.
See, you are free to ignore whatever measures MPAA and RIAA impose on you. It is your own decision to buy from companies who inherently do not trust you. It is only a matter of time before society realizes that the free world has been transformed into a world where a few megacorporations decide what you are allowed to think. Precisely what the leaders of the free world have been accusing other nations of.
But when that happens, consumers have the power to shut down that system. There is no need to consume things like music, movies, television programmes, etc. Stop that consumption and the system will die, because the corporations that run the system will die. And as long as there remain alternatives, there is an even stronger method: only buy stuff that is not from companies in such an alliance.
Then a system like TCPA can remain in place for situations where both ends of the link like to have trust. Like in secure transactions, or when checking if a system has been hacked or infected.
There is no "the secret key". You think that SSL is not a fully open standard because websites do not give you the secret key of their certificates?
A signed binary only means you can trust the binary as much as you trust the signer. Nothing more or less. The TCPA means that publishers of data can decide that they do not hand over their data to applications that *they* don't trust. That means it can be used for DRM, but it also means it can be used for secure transactions, etc. It does not restrict your possibilities to run modified code, but it can restrict your possibilities to do useful things with them. That is based on the lack of trust in you. Your best defense is not to trust publishers that do not trust you.
So, when a music publisher sends out files that can only play on a TCPA DRM platform, stop buying from him. When other consumers do the same, the publisher will go bankrupt and others will step in.
Trusted software means the binary has been signed and the running binary has not been tampered with.
This does not mean you cannot have the source or you cannot modify it. Only, the modified version will not be trusted. That is what trusted code is all about.
So there is no conflict between GPL and trusted code. There is a conflict between modified code and trust, but that is the purpose of the entire concept.
Of course you can generate your own secret key, publish the public key, sign your binaries, and everyone can verify that they are genuine binaries from you. Then, anyone who trusts you, can trust your binaries just as they trust binaries signed by Microsoft.
This decision was made long ago, when there was only a single address space and it was convenient to have the program at a fixed address at the beginning of memory, and the stack fixed at the end.
The "stack grows down" has been embedded in the hardware design and now it cannot be changed easily.
30 bits must have been made up by the marketing guy. "there are one billion possible combinations". That was probably the largest number he could think of.
