Anybody who needs web access to configure their router shouldn't be programming their router. Simple as that.
the only command you needed to know to stop Code Red from toasting your DSL connection is "no ip http server".
As much as I hate to say it, the people responsible for Code Red propagating are not Microsoft (and you don't know how much I want to blame them...), but those that DIDN'T secure their webservers by applying the patch.
QWest is not responsible for the system outage, the inept system administrators are....
PPPoE is not inefficient, and in fact it is an Internet standard.
The MTU has nothing to do with anything.
If PPPoE encapsulated the data packet, then it is inefficient and the MTU has everything to with everything.
Anytime you encapsulate, you reduce the MTU of your packet by roughly 25Bytes. Applications that attempt to use the full ethernet MTU then have to fragment their data. This requires CPU cycles and bandwidth. And if you want to create a tunnel through that... you reduce the MTU again.
I do this stuff for a living. I suggest you learn about encapsulation and tunnelling before you spout off. And next time, post under a real ID, not an anonymous coward.
Distinctions between priveledged users and non-privelidged users.
Ability to block destination and source IPs (let's see you create an ACL under windows)
An entire community of programmers to fix the problem.
I remember when MS patched some stack vulnerability by only looking for the signature of the attack, (I believe it was to counter winnuke.) and then someone changed the signature of the attack.....
Sorry man, I don't buy the argument that linux and windows are equally secure. I think you're pulling strings out of your ear.
Any casual user who buys a boxed set every time is a goddamn moron
Or maybe they just want to support the OSS and actually pay the distro authors for their work...
I know I have never paid for M$ software. I have purchased second hand a copy of Warp 3 Red Box though. And I have probably spent $300 on Distros in the last two years.
This is really an electronics engineering problem, and not a computer engineering problem.
If you tranform the time domains waveform of both a sine and square wave into the frequency domain you will see two very different waveforms.
The Sine wave will be represented by a single "peak" at its fundamental frequency (ie 60Hz), whereas the square wave will have a "peak" at its fundamental frequency as well as harmonics present at each odd harmonic of the fundamental.
Linear power supply transformers act as low pass filters (inductive) and if you watch the output of a transformer you will see some filter effects on a square wave inputted. Additionally, once you rectify the signal, it is typically put through another lowpass filter (capacitive or inductive) which cleans up the signal even more. The regulator circuit cleans it up significantly from that point on.
The concern is the initial "spike" needed to create the rising edge of the square wave. Ideally (as was posted before) we don't generate that "spike". However, if you've done any transformer theory, you know it takes time to build up the flux in the core of the transformer. The difference is that the flux will build up faster with a square wave than with a sine wave and introduces the chance of saturating the transformer. If you saturate the transformer, it will stop 'transforming' and the output will drop off prematurely. You also risk overheating the transformer (ie letting the smoke out.)
Most manufacturers build their transformers capable of handling the flux generated by a square wave. The key here is that YMMV. Also, square waves are audibly and spectrally noisy when going through transformers.
As for switching power supplies, the input power is rectified first (as noted by a previous poster), filtered and then "switched" to generate the output. A square wave input will not harm the rectifiers in any way.
Here's the catch. The control circuit of a switching supply would NOT be able to handle the square input. There are too many harmonics.
This is where "modified sine wave" more accurately labelled "stepped square wave". The aim in that system is to reduce the number of harmonics and their intensity and the average voltage of the waveform. A sine wave's average voltage is lower than that of a square wave as is its RMS voltage. This is so that more sensitive equipment can be connected to the UPS.
One final note. I recommend getting a "True On-Line UPS" instead of a Traditional UPS (ie Back-UPS).
The difference is that a "true on-line"'s inverter is always running and usually generates a truer sine-wave. The Power supply portion drives the inverter and keeps the battery charged. The traditional type switches the inverter on and into the circuit if the power dips below a certain threshold. The engineers of these UPSs have done an excellent job making sure that power isn't interrupted in the switching process, but let's face it, anytime you switch a power source, you generate spikes which could damage your data, equipment or crash your system(s). The "true on-line"s do no switching. For them, the power supply shut off, but the batteries are still supplying power. It is completely transparent to the end equipment.
maybe you should rename the program or put some password protection on it (put it in the program itself, so that you have to give it a password in order for it to start)
Alternatively, you could just carry it around on a floppy disk.
Here in Canada, the law requires banks and other financial institutions to write their contracts in "plain english". That is the contract you sign. Makes it easy to deal with them and you don't get screwed by trying to read "legalese".
Because in places like Canada, in order to get a.ca domain, you have to be nationally registered, which means you have a business office in more than one province or pay $200 to be nationally registered. Otherwise you get stuck with a lame.bc.ca or.ca
While I'm not sure about the total truth of the bible anymore, I know that this passage at least warns us of similar things to the "mark of the beast" (I grew up in church.. I have a pretty good handle on the dogma.)
If you look at the bible, there are a lot of prophesy, and some of it seems to have come to pass.
More importantly, the warnings that are issued are done so, usually, for an "undocumented" reason. Think of it. The ppl who wrote these passages had no concept of our technology. Tracking somebody across the known world was pretty tough. Privacy? Not a problem. No real way to monitor a person. So, they wrote this the only way they understood
I don't really know if I've made my point here, but to summarize, this could easily be construed to be the "Mark of the Beast" (something I consider a strong possibility) so I know I will be refusing.
Besides, the personal privacy violations alone.....
I think you people need to take a broader view. DMCA has no jurisdiction in Canada or Sweden. No US law does.
This is a scare tactic no doubt, and Mattel looks even worse because (if I read the article right) they are filing suit against a Canadian Citizen in a US State court.
If these corps really want to fight, come to my country and file suit against these people using the Criminal Code of Canada and the Laws written by Parliament. File suit where the alleged "crime" was committed.
Just because an American court issues a court order doesn't mean that the Canadian Courts will uphold the order. (IANAL, BTW)
Personally, if there was software out there good enough to actually purchase, I would. I deal with proprietary code daily (I write the stuff) and understand the need for it in some circumstances. I also understand the reason Transmeta closed their code. They closed the Crusoe code because if they make any hardware changes to the chip, it would change the code. Therefore, using the x86 instruction set as the "API" provides a common base making their chips compatible with ALL x86 processors yet freeing them up to change the physical design of the chip as necessary. If we wrote for the chip directly, even a small change that alters the VLIW instruction set will require a recompile of ALL operating systems so that they can operate on that particular revision of the chip. We'd end up with thousands of compiles of each OS... It would become unweildly. In addition, locking in the VLIW instruction set would cause the processor to become larger and less efficient with each iteration, just like the Intel x86 currently in production. This is what they wanted to avoid.
Personally, I applaud them for doing what they are doing, and next year at this time, I will more than likely buy a device using their processor. I was thinking of a tablet.:-)
StarOffice for Win32 has a very nice feature with respect to cookies. If you set the browser up to ask you about cookies, you can then select if you ever want to get a cookie from that server ever again.
There are too many commercial entities on the internet ruining what was supposed to be an educational and community oriented backbone.
What was supposed to be an open platform, has been closed up by greedy corporations. People with ideologies that are 180deg out from the ideologies of people that created the internet.
I'm not just referring to those corps that "close" the protocols and standards, but also those that "close" the flow of freedom (such as the resent lawsuits over domain names, et al.)
That is apparently very messy in the US because some states require you to tell them how much you spent in mail order from other states/countries (though most don't and the state looks the other way.)
Here in B.C., most items are bought via mail order are not taxed by the province, but some items are illegal to bring across provincial borders (tobacco products mostly) or are taxed because you have to register with the government anyways (car registration/insurance)
Mind you, B.C. is the only place where the insurance board (ICBC) is also the DMV...:-(
Just to clarify, NTFS was developed in conjunction with IBM for a server platform. There is another version of HPFS known as HPFS386 which does support the same things as NTFS does, but is only included with Warp Server.
I also question that Warp 4 was technically superior to NT. Again, OS/2 and NT are close cousins, and they both have the same achillies heel... video drivers at ring0...:-(
Personally, I've used both and found OS/2 to be far more powerful and user friendly than NT.

Thank GOD I live in the most connected society in the world - Canada.
Here is B.C., DSL is a commercial-grade service. They sell it as such, and the CRTC makes damn sure they provide a commercial-grade service.
