While I won't get into the reliability of Linux journalling filesystems I can tell you that few companies would use a high-end system without such a filesystem.
You can waste a very large amount of time checking a filesystem after the system goes down unexpectedly (for whatever reason).
A journaling filesystem adds very little overhead, except when a large number of files are created, or deleted. As such, it is NOT going to have a large impact to a well configured webserver
You will easily get 10meter horizontal accuracy from an off the shelf unit today. Vertical accuracy is another story. (Seems they try to accumulate the error ito the vertical component, makes sense if your on the ground, sucks if your in the air.)
After doing a lot of research on the net regarding GPS (having purchased one a few months ago) I'd like to comment on what you've said. DGPS only gets about 3-5meter accuracy (95% of the time, or some such statistic). DGPS is used to counter selective availability and some of the distortion caused by various atmospheric conditions. Survey units use a more robus version which actually gives them only distance from a specific point. (A very precise point mind you). If you know where that point is located very accuratly you can convert the data to get precise locations. Unfortunatly there are a large number of errors which have to be accounted for and the results for survey units look bizzar.
The really cool thing is, if you have 2 garmin units you can post-process the information later and get a very similar level of accuracy. But again, it is only as good as the set point you started with.
First, I'd like to shoot anybody who claims you cannot patent an idea. The american Patent office seems to do a good job of issuing patents for ideas.
When a mechanism, a process and an implementation of a way for an end user to perform the action specified in the idea is SO BLOODY OBVIOUS TO ANYBODY in the industry there is ngeligable difference between patenting an idea, or a mechanism/process/implementation.
The patent is NOT perfectly valid. As others have pointed out similar systems existed in the broadcast industry for years. Doing via analog that which we can now do by digital. The difference is hardly significant. The obviousness of a patent is also NOT applied to a lay person, but rather is supposed to apply to people with a similar background. So, while to your grandmother it may not have been obvious, the idea itself was obvious. (Who hasn't wanted to stop a tv broadcast to continue it when they return without missing anything, and without waiting for the recording to complete.) A method of implementing this was obvious well before 1992, the equipment to make it feasable to do in the home, well, that IS another story all together. But getting the patent didn't and doesn't require it actually be feasable. It should. It used to require a working model, as such would have prevented most of the stupid patents from the last 10 years.
perhaps Backbone provers should not be allowed to filter data. Leaving it at the ISP level. Where the end consumer may actually have a choice.
I've been effected by network bans. I've never been a cause of them, and the solution to fixing it is NOT acceptable to me either. (cablemodem is a monopoly here, while DSL is a joke!).
Email filtering and blacklists should be done as close to the end-user as possible. In some cases this means it should be user filtering his own mail, in others the ISP. Blacklisting domains so they are in-accessable through backbone providers is sickening. Right now it is done for spam, but a year from now it could be done for Porn. For free encryption tools, etc. Anything some group wants banned.
Never setup a company that does any form of business with the United States without listing its primary contacts. You could find yourself in jail upon entering a state where a judgement was found against you even if you were never served with the lawsuit in the first place.
Doesn't matter whether you are American or not. Several states allow lawsuit to proceed if the other party cannot be contacted. Note: The lawsuit will likely NOT be in your favour if you cannot be contacted.
This has happened to a few Canadian companies, the president of one such company entered the state where a lawsuit had been filed and completed a year before. He found himself in jail for failing to follow the judgement. (Details sketchy because I do not remember enough details to find it. Was about 3 years ago.)
Certain backbone providers have used the blacklists to restrict all types of traffic intended for a blacklisted site. When they do this they cross the line, but many individuals have no method to change backbone providers. In many places all providers have the same backbopne provider.
I hate spam. But I hate the blacklists as much. They both effect my rights.
GPS Satalites are continuously receiving update data for their positions. They are adjusted in obit continually by ground control as well. Virtually all issues of accuracy in the GPS is because of the ionosphere. Not the satalite orbits. GPS is a highly dynamic system. If you leave the typical GPS receiver off for a period of time, say 2 weeks, it takes considably longer to re-establish it's position because it has not received updates in that time. They also get slightly confused and take longer if you transport them over large distances when off.
They will autmaticly re-aquire on their own if you give them a chance, and they will then download new data from the satalites so it can better predict which satalites are in view next time.
As someone else mentioned, GPS is one-way transmission. GPS received know what data they should expect to receive at a given time. BY knowing when the signal was sent, and how long it took to receive it they can work out how far they are from each satalite in range. Get 3 or 4 and you know where you are quite accuratly. (Interestingly enough it should be possible in space to get a much more accurate result than on the ground. No atmosphere to screw with the signal. Currently that is the most significant source of error.).
GPS Satalites orbit on a 12hr schedule (I think). But 2 new satalites used for GPS are geosynchronous. (used for WAAS enabled receivers. They send atmospheric correction data to increase the accuracy, and as bonus can act as GPS satalites as well.).
By the way, GPS is 'free', there is no charge to use the service above buying a receiver. And if your going to use the sun/stars for navigation your still going to have to have somehting interpret the data...
First, it is quite possible the programmer involved simply copied the relevent lines and pasted into into a new project.
It is also quite possible someone else documented the structures and the programmer re-build the header file from said documentation. The structures themselves would likely end up with the same names, and depending on the prevalining naming convention at the time it may look as close as it does without actually being a direct violation.
Header files of this nature are ALWAYS going to look very similar when it is for the same device. As for 'his IP' based on reverse engineering the interface. Sure, except copyright doesn't exist for anything except the actual implementation. documenting it and redeveloping it IS NOT a copyright violation.
A header file such as this is close to simply respecified facts.
I was suprised to find my GPS unit is still working perfectly today. I expected they would enable Selective Availability and, or entirly disable the GPS service for atleast 48hrs.
I bought a GPS a couple of months ago, even the $300C model I have would be adaquate to navigate a plane if you had someone capable of using the planes controls. Even if all the electronic navigation aids on the aircraft were non-functional a small handheld GPS unit would be adaquate. (Even with selective availability it would get you within 100meters in pitchblack, never mind this was done after sunrise.
A 28.8Kbps modem delivery good video and sound? Uh-huh. It's the Holy Grail. The last guy I heard demoing it ended up being on a wanted list for fraud. For all we know the machine had a 802.11b wireless card and was receiving multiple transmissions of the datastream. (Assuming any level of auditing was actualy done to verify that any data was over the 28.8 connection.)
Slashdot is a cutting service with a bias in favour of Linux, Open SOurce and Tech toys. A dabling of Science and Rights (as releated to technology).
Mentioning Slahdot and Journalism in the same article is misleading. Slashdot personel write very little content. They do add spin to some articles, which tends to show their bias. But then, Slashdot has never had a problem exposings its bias anyway. it is what it is.
Truth be told, most of the bias in favour of Linux/Open Source is in the comments, not the articles and editorial posted.
It is possible to determine if someone is using NAT in many systems. Linux is one. I believe FreeBSD's NAT system is much more difficult to determin. (All operating systems tend to open unspecified ports in specific sequences, ie: 1025 is used for a request, then 1026, etc. But using NAT Linux uses much higher port numbers in a different pattern. Making possible to detect.
Qwest shouldn't be held responsible for the worm, or it's direct actions.
On the other hand, I believe they (along with others) had problems relating to bugs in the DSL modems. Bugs which they had a patch for but didn't inform their customers about immediatly. For that they are potentially responsible for.
LanManager was not the pre-cursor to OS/2. It was the precusor to it's networking environment, but not the OS itself. (I've used versions that didn't include networking.).
Besides, LanServer and LanManager were Microsoft and IBM's product at the same time. Hence they are very similar. (Not identical).
same here. I don't use the content, except I checked when they changed to Excite@home and have the same problem with the tv listings you have.
They do use @home's mail servers for instance, so if @home goes under we'll probably get stuck with new email address'. Oh well, not the end of the world.

For those of us who are already paying for the service, are there any reasonable options? Is it possible to have a second cable box for digital cable?
(Slave mode or something.)

As a Canadian I only need some form of identification. Drivers license & birth certificate are adaquate.
(And that, as far as I can tell, is only to travel through the border, but I would never travel without some for of ID.).

Why not, your significantly made up of carbon anyway.
I don't even think it would be that hard to fake.
I hope they use it on their StrongARM based Palms after making appropriate changes to use it on a hand-held device.
It will be interesting to see.
