While I was considering getting broadband, I saw the price go from $25 a month to $30, to $40 and now to $50 dollars a month in my area. All the providers did it. Even my friends who already signed contracts and had service saw their costs rise. The contract fixed the length of the term, not the price so they were able to jack up the prices on their subscriber base. People who thought that their service would be $30 a month, are now looking at $50 a month and there is no added value to the service. The only way you escape is if you paid up front.
Until the corps can get their business practices under control, I will stay with dialup and use my company's internet connection for downloading those NetBSD ISOs. At home I only check email and do a little browsing, so the slowness is tolerable. Fastness certianly is not worth $50, especially when they advertise "50 times faster than dialup" and deliver 3-4 times as fast.
BTW, my dialup does the same thing (random price increases), but they are fewer and farther between and also only a dollar or two.
A typical auto engine has difficulty burning hydrogen because the internal surface of the cylinders reaches a temperature which is sufficient to ignite hydrogen. This causes problems because when the hydrogen enters the chamber, it combusts. With the valve open and the piston in a less than optimal position, a good deal of power is lost (if it runs at all).
Rotary engines and gas turbines do not suffer from this problem (their intakes separated from their combustion chambers and are relatively cool) and are better suited to H2 as a fuel.
I drag myself to classes and through projects, and it all seems really pointless--I'm just implementing what's written in the book, and eradicating the countless off-by-one bugs is nothing short of mind-numbing
Try getting involved in some research projects. It probably should not be in the CS department, but rather one of the other departments. Lend you CS expertise to a different kind of undertaking. You will also get a chance to learn about something outside of CS as well as picking up some usefull experience.
If you can't find a school project to work on, make one of your own. Again try to go outside of a pure CS project and delve into something new. Think about ways your CS experience could improve something else and then do it.
For example, when I was in school, I worked on projects for the physics department and the business department. The former needed some automated data collection and the latter needed some statistical modelling. Both provided me a well needed break from the ordinary as well as intoducing me to some real world problems.
Although I have been in the field for about 6 years now (working for a major telecom mfgr), and I still take on "outside" projects from time to time. Be it setting up a webserver for a local charity or building a remote control boat from scratch, both provide me the relief from the monotony of always working on someone else's dream. It is refreshing and rewarding and helps you out back in "the world".
Then, we could have biostorage in our brains with a human/machine interface between.
That's all well and good until you try out some new beta software, only to discover that someone didn't terminate a string properly and you end up overwriting your heartbeat() routine.
With Linux, customers "end up being in the operating systems business," managing software updates and security patches while making sure the multitude of software packages don't conflict with each other," Miller said. "That's the job of a software vendor like Microsoft."
I guess Microsoft thinks that its software never needs updates or patches and all the software written for Windows doesn't conflict.
Oh, wait.... that's their hook. If you point out that WinXX has the same problems, MS points you to their new snazzy WinXP-.NET achitecture and offers to make that all go away.
Somehow I don't think that MS will be able to live up to that statement.
When my dog doesn't like my mood, she runs halfway down the block and hides under a tree. When this car doesn't like my mood, is it going to go down to the supermarket and hide in the back alley?
Use cleartext that is part of the system such as text from the man page for the "ls" command. This is an example, but you'd want to pick a lengthy man page. Start and end in the middle of a word. Also, do two or three cut and pastes. One cut would be simple to break. Two or three, and now they are in trouble. becuase there is all kinds of variations on multiple cuts. Or to be really vicious, open a common image file in a text editor and cut and paste from that. There's some entropy!
A typical solar panel (Siemens 110) generates about 100 watts, takes up about.85 square meters, and costs about $500 USD. If you assume that you have 8 hours of daylight which produces good amounts of power, then you need a system that can generate about 14,000/8 = 1750 watts. This means 18 panels.
Keep in mind the following...
1) The car is only 100hp - how many people will give up their 300hp sport utilities for a compact car? And do you want to ride in a flimsy lightweight vehicle and let Bubba in his pickup truck smoosh you in a 15mph accident?
2) You better get 8 hours of good daylight or you are not going to work tomorrow.
3) I have assumed a 100% conversion from sunlight power to H2. There is a loss here, but I do not know how much it is.
Solar power is not as good as gasoline because you can't go to the store and pick some up. Hydrogen has all hinds of handling issues to be resolved in order to be safely handled by the public.
From what I understand, the pressures needed to maintain propane in a liquid state are much lower than hydrogen at room temperature. Hydrogen requires such high pressures to maintain a liquid state at room temperature, that a practical container has yet to be developed. That is why liquid hydrogen is cooled to a temperture where the pressures are manageable. But then you have to keep it cool.
This is what I have heard and it seems to jive with the PV=nRT formula learned in high school chemistry.
But thousands of American civilians are already dead in this conflict, greater civilian losses than in any war in U.S. history.
Seems to me more than 5000 civilians died in the US Civil War. And it was not from the side-effects of war. Civilians were legitamate targets back in those days and were fired on by both sides. I don't have a link, but Gettysburg seems to be a good place to start researching this.
Although this is a bit offtopic, I do find it irritating when you hear all the "This is the first time that..." crap in the media. We've been attacked on our soil before, had our territory occupied before, and yes, our civilians have been attacked and killed in large numbers in war before. This seems to be a tool that journalists use in order to make it look like the story they are reporting is some radically new type of event, when in reality it is just a slightly different spin on what has been happening for centuries.
1) When a new app is installed, just put a dialog box that allows the user to associate the extensions with the new program.
2) Also, put this code in the program itself, accessable from the menu.
3) Put an article in the help file about how to do it manually. There are ways to easily re-register an application. The article makes it sound so difficult (it's not).
How do you change the application on the Mac? Why not provide a GPL'ed program to do this task for grandma, and publicize the hell out of it?
IBM licenses hard drive technology because they have the patents on the technology used to coat the surface of the disks and the read/write head technology. If you want to make competetive hard drives, you need to pay your IBM tax. That's what I read when I was doing some research on hard drive technology.
It is basically a commodity market. Everyone makes pretty much the same drives, but of course quality varies from company to company. Most of the big names are OK because they would not remain in business long if everyone knew that the failure rate on their hard drives was 3x of their competitors.
This whole mess simply sounds like a bad batch. It happens in all companies. How the company handles the returns is the main factor for my buying decisions. Maxtor is good because you do not need a receipt or any proof of purchase. You could buy a failed Maxtor drive at a garage sale for $1 and if it was made in the last 3 years, then you could return it for a replacement.
All of my drives (5) are Maxtors and the oldest one is more than 5 years old now(540MB). I've had no failures in that time.
I believe that the current process for maufacturing hydrogen is to break down hydrocarbons, which is easier than splitting water. I forget which hydrocarbons, but it is basically one of the fuels derived from crude oil. But this still begs the question, why not use the primary fuel source in the first place?
You don't have to be an engineer to figure out that the lower the fire, the more likely the collapse due to the increasing weight on the affected area.
The upper floors are lighter than the lower floors because they do not need to support the whole building. They make them lighter by using fewer materials. Fewer materials means that the upper floors are weaker. Granted they are under a lighter load, but they are still weaker.
If you want to make them stronger, then you need to increase the weight. If you increase the weight, then you need to beef up the lower floors. This adds expense to the system.
The other issue is that fuel fires cannot be adequatly handled by a water based sprinkler system. WTC's fire suppression (and most other buildings) was never designed to suppress a liquid fuel fire. They are principally designed to suppress solid fuel fires like a filing cabinet or an electrical fire.
The building was not poorly designed. It survived long enough to allow 15000+ people to escape. Sure we learned some lessons, but I doubt that liquid fuel fire suppression is going to make it into the building codes.
Would asbestos have saved the day? I do not know. It may have given the occupants an extra 15 minutes to escape. But the main issue was not the fire itself, but the unanticipated fuel type.
This topic comes up a lot especially in alternative fuels discussions. This is the info that I have. It may not be 100% accurate, though.
Issue 1: Hydrogen is a gas, which means that you need to compress it in order to get enough fuel onboard. Fuel equipment now has to deal with the increased pressure. This adds expense and weight to whatever it is you are building. Weight is bad for airplanes. Liquid petroleum fuels are very dense and do not need pressurized containers. Thus a full load can be carried without the need for bulky equipment.
Issue 2: The economy is designed to handle liquid fuels. Gasses are handled, but in much smaller quantities. Changing the infrastructure to deal with handling gasses is probably the most prohibitive part of using gaseous hydrogen as a fuel. And don't bother with liquid hydrogen. The handling issues associated with that are worse than compressed gas (insulation, boil-off vents, etc).
On the plus side, hydrogen is well suited to gas turbines and jet engines. Clean and efficient. It's just a bitch to store and handle.
When someone makes room-temperature liquid hydrogen, that'll be the day we all switch.
The signalling is pretty much the same, but the codes are different. They are something like . The problem is the MFG code, and is the reason that a Sony reciever remote can't turn up the volume for a Pioneer. To their defense, if you had a Sony receiver AND a Pioneer receiver, how would the receivers know which one you want to talk to? If they did make this standard, then everyone would complain that turning up the volume for their receiver also turns up the volume for the TV.
No doubt they will also be responsible for as many, maybe more, casualties as the consoles explode whenever the ship is in a crisis. One can only assume that the consoles got better with time. Whether this means better at not exploding or better at killing the operator is an excercise left to the reader.
One of the things I love about the Sim line was the interoperability between some of their titles. For SimCity2000 I also bought SimCopter and Streets of SimCity. These games allowed you to fly and drive around your city. I'd love to be able to drive and fly in my SimCity3000 cities.
But the crooks could still write their own crypto software and then run it through the crypto chip. Then when Johnny Law decodes the bitstream, he gets another bitstream that is indistinguishable from noise.
The government has a choice. Have crypto be available to law abiding and the crooks or to have the crypto available to only the crooks. As you can see, the crooks will always have crypto available to them.
The government cannot even stop someone from bringing cocaine into the country, how the hell are they going to stop a crypto program from spreading?
I went to the ISO mirrors and all the sites are either denying access or do not have the 1.5.2 directory set up yet. You may want to give it a couple days before trying.
Perhaps the crew at slashdot can create a temporary mirror site where they cache a site before they post the article. Then they can have an option on the page to either go to the referenced site or to view the cached site. Granted this would take up some space, but they would only need to do it for a couple, maybe three days, then they could retire the cache and refer everyone to the original site. This would keep the slashdot effect to a minimum. Of course I am not sure about the legal ramifications of this.
I do not have any servers, but this works well and has the following features...
- DHCP server
- NAT
- RJ-45 for connection to Cable/DSL and a DB-9 for connection to a modem.
I particularly like the fact that it can do Cable/DSL and Dial-up. Since I am moving a lot, I never know what is going to be available. You can even use the dial-up as a backup, should the Cable/DSL fail. Web based administration is straightforward. But I can't comment on that beyond the basics.
Power consumption is low (22W I think) and it is a lot quieter and much smaller than a PC.
It is good for my simple needs, but you may need more for your servers.
