That is because at 320×200 CGA only had 4 colours. Not 4 bit, only 4 seperate colours. Worst, there were only two pallets to choose from in 320x200 mode.
The problem with MacOS parental controls is that it basically hides apps from the finder. Other applications can be used to circumvent the contols. The only way to properly implement MacOS parental controls is to use fine grained ACLs at the kernel and filesystem level. Apple can implement these ACLs, but it is going to be a lot of work.
The problem with SELinux is that it is a hard beast to manage. SELinux can be configured they way that you suggest. But someone needs to set policies for every file. Worst different policies may be required depending on the intended use of the computer. Google for some of the problems FC5 users are having with SELinux. The Windows NT kernel, with NTFS, has almost the same capabilities as SELinux. The fact that no one has come out with a super set of policies suggests that it is not that simple.
I believe once the percentage of Biofuel in normal fuel goes above ~10% this is when modifications are needed to the vehicle.
The modifications are minimal. Some seals and fuel lines may need to be replaced, and a larger fuel fiter is often required. Any diesel engine can be converted to run 100% unrefinned cooking oil by simply adding a cooking oil fuel tank. The problem with most bio-diesel is that the fuel becomes too thick at lower temperatures. In the artic 2% bio-diesel may be too much. In California you may be able to run 100% all year long. Engines that run on unrefinned cooking oil typically start on dino-diesel and heat the cooking oil with waste heat from the engine.
2-3 essays per week for a single course is more then excessive. There simply isn't time in the week for that. A typical college work load should be about 60 hours a week for all courses. With a typical 5-6 course load that gives 12 hours or less per course. At the first year university level 3-5 hours will be spent in the class room (includeing lab time) per course. That leaves maybe 9 hours to research and write essays. Many students (both science and arts)q will struggle to finish a single essay in that time. This assumes that there is no other assignments for the writing class.
In North America there is a cycle in mining safety. As a result of accidents authorities impose various safety regulations. After several years of safe mining the companies point to their safety records and convince authorities that certain regulations are no longer needed. After the regulations are relaxed (or no stop being enforced) serious accidents happen.
It depends on the industry, type of employment, and the person. In general do not bother with counter offers as per GP. It will probably backfire 99% of the time. However there are people who are so good that they can demand higher pay greater job flexibility. Some industries and locations are also more accomodateing. At one point big tech companies expected high value employees to take a "sebatical" and work one or two years with a competitor. There are also a number of jobs where people are hired based on the person, not the skills. People as actors, some senior management, certain professionals (doctors, lawyers, engineers, architechs), and some coporate sales. Not a lot of people fit into that category. Most programmers would not fit into that category, but someone such as Linus Torvalds would.
The problem with WEP 40/64bit is that the key is only 40bit and can be quickly attacked with brute force. The problem with WEP 128bit is that the standard implemented RC4 encryption poorly and known weak IVs, initialization vectors, are used. To crack WEP an attacker needs to collect a large number of packets that use the weak IVs. The time it takes to collect these packets depends on the ammount of traffic and can take days or months. Some access points and wireless cards have a driver option to disable weak IVs.
WPA is much stronger and WPA2 is even better. WPA is vulnerable to weak keys. This is more a problem for pre-shared keys (the common home setup) then for certificate based authentication. The authentication mechanism uses 4 packets. Those 4 packets can be captured and attacked using brute force offline. IIRC the attack is not that fast and typically uses dictionary based attacks.
Use WPA with a strong passphrase and you should be safe. A passphrase with 16+ chars and numerals should be good. Some access points have buggy webbased management and can't accept other puctuation or special chars.
Ofcourse this won't stop a well financed (state sponsored) attacker. It will stop the neighbour's script-kiddie teenager.
it becomes a bit different with public-key cryptography
Not really. Public key crytography still requires a secure channel to exchange the public keys. If a secure channel is not used to exchange the public keys then the system is vulnerable to a man in the middle attack. The big advantage to public keys is simple key management. Alice does not need to maintain a private pre-shared key for every person with whom she wishes to comunicate.
Public keys can also be chained creating odd secure channels. A intermediary can be used to create the secure with no action on the part of the intermediary. For example: Alice trusts Bob. Bob trusts Charlie. Alice can trust Charlie via Bob. If pre-shared keys were used Bob would need to actively assist Alice and Charlie create their trust relationship. Private pre-shared keys could also be chained, but it would become impossibly messy in short order.
The problems happen when a business finds that an update causes problems for important software. Given the list of fixes the admins may determine that the problem fixed in the update does not effect the system. e.g. the update is for a bug in telnet, but telnet is blocked by the firewall. So the update is not installed. However unknown to the admins the update also fixes a very serious bug that does affect the system.
System admins need to know the full details of the updates.
I have played, and still have the books of, D&D Basic to Master, AD&D 1, 2, and 3. D20 is the best D&D system. The base D20 mechanics are consistent with few special cases or weird rules. More importantly the D20 system is easily extensible. My group's house rules were easily ported over.
I have a PC Power and Cooling "Silencer" 470. It is quiet and good. I believe my quiet Seagate is louder. It is a heavy, no-nonsense power supply. I will never buy another "quiet" Enermax or Antec supply again.
Many power supplies from the big names have dubious features as they chase the enthusiast market. These companies are driven by marketing. PC Power and Cooling have engineered their supplies to be power supplies first, and quiet second. PC Power and Cooling is one of the few companies still driven by engineering.
For reference: The 470w supply is used in a system with an AMD x2 3800 (OCed), XFX 7800GTX, and Seagate 7200.8 80GB. The case is a steel Antec 3000 with stock low RPM 120mm fan. The cpu has a Zalman CNPS7700, and the chipset heatsink was replaced with a fanless Zalman heatsink (I recommand both). The XFX heatsink is stock. This system in not silent, but quiet. It could be used in a home theater system and it is unlikely anyone would notice. The noise from outside the house is generally louder. The noise from the forced air heating and cooling is louder.
78-82% is not very efficient unless you are a mechanical engineer. 90% is very efficient, but I don't know of any PC power supplies that are that good. The best PC supplies are about 85%. 80% is not bad, but it is not amazing either.
the PC PSU is generally assumed to suck air out of the case
Not only is moving air assumed, it is part of the ATX specification. At least it is in the original ATX spec. You can find the pdfs online. Look at the mechanical specification and you should see a bit about air movement.
Well don't bother using OTR. It dosen't work as designed and probably can't work. It susceptible to trivial man in the middle attacks. The OTR developers now acknowledge this failure and recommend that you use an out of band communication (phone call) to exchange keys. OTR attempts to provide repudiation and authentication. These features conflict.
The number of Apple laptops at confrences is useless anecdotal evidence. Look that the number of laptops sold as published by Apple in their SEC fillings. Note how in mid 1994 laptops outsold desktops. Note how the number of laptops sold dropped sharply in 1995 (and end of 1994). Check with Dell, and HP. Note how their laptops sales have increased faster then desktop sales.
Yes, Apple's laptop lineup was suffering. Apple has lost a year and a half of increased laptop sales.

No, we didn't play tricks while in school like you see in Disney movies.

The formatting on all three breaks on my 133dpi screen as well. I expect better in a site like /.

think about it:
Say that there is a display that pixels that are 4mm wide and 3 mm tall. Say the display is 4 pixels wide, and 3 pixels tall.
1) What is the width and height of the display?
2) What is the width to height ratio of the display?
3) How is what the gp described impossible?

In Canada and England tabled means "present formally for discussion or consideration at a meeting." In the USA tabled means "postpone consideration of." Yes it is confussing.

$12 for a CFL is about 3 times too expensive. Even the grocery store charges less then $6 for a 13-15W CFL.
