We told our boss last summer that we can bring our project in on time (we are about 5 months behind schedual, been holding steady since then) for brand new RX7s. We have a surprizingly large club of RX7 owners here, though the big pickups are more popular)
PS, for those that don't know Mazda stoped making the RX7 a couple years ago.
PPS, the RX7 is a cool car. Wankel engine is something that all geeks can love for the beauty of the design.
Hate to burst your bubble, but software modems are NOT DSP chips. They instead turn your CPU into a DSP chip, but since DSP is a hard task (didn't it mention 10% of a 400mhz PII?) the CPU does a bad job. The DSP can do FFT very fast as you say, but that isn't what a winmodem does as we are talking about them.
Now if you has said a regular modem (ie. $100 each) you would be right, all those modems are these days is a DSP chip and some rom. My USR (3com) courior could be everything you say if only 3com would release the specs! Technically this is a software modem as you write code for the DSP to decode the signal, but typically we don't consider them one because the code resides in (flash or similear) ROM.
In recient cost cutting moves, my boss was told they no longer trust him to decide when to buy lunch. (though he said right off that he can be creative about the exceptions) And he was not excessive in buying us lunch either.
Three years ago we were promised a gym (we are at a brance several states from headquarters, they got one already) by upper managemtn. Unfortunatly the lower side of the upper managemtn has managed to kill this deal every time through their blundering.
If I could take the heat (its only 75 today, and I could barely do a 1/4 mile walk outside cause of the heat) I'd consider moving. I don't think I could live someplace as crowed as Calf. At least my rent is cheap, try beating living with the parents for cheap!
Perhaps I'm wrong, but my understand is some people have the opertunity to buy redhat shares before anyone else. You can go to your regular broker on the day of the IPO, and buy all the shares you want, up to the limit of your money, or issued shares. Those who got the letter can go to ETrade before the IPO date, and buy some shares. Not all they want, but redhat has reserved some shares for them. The advantage is they get these shares at the IPO price, not at whatever price redhat trades at on the first day!
Normally a deal like that is given on to the big investors, generally for favors. Often it is "In return for buying shares before the IPO, you will cover us in the press one month after the IPO." I mentioned one month latter because many of those involed with IPOs legally need to keep their months shut about it until one month latter, which may affect some redhat investors. Redhat is giving this deal to little guys in recignition that the little guy made them big.
Not true. I have pulled a processor from a running system once in a while, and the system kept running without problem.
I'm told there are some systems that you can upgrade the memory at any time too, but I don't normally work with those.
For hot swap there are two issues, the hardware needs to be able to do this without damage electricly, and support what software cannot do. That is easy (relativly). The software needs to recignise the swap and deal with it. For riad the only hard part is detecting a new disk, but pocessors gets tricky.
It isn't that bad. While it is true ETrade makes interest, they pay that to you. It probably isn't 4%, because it is compunded daily. However they are paying you the interest earned while the money is in their account. I'm sure they get a little off the top of that, and they take the whole amount while the check is in the mail, is about $.70 per person, stamps are $.32, and envlopes are not free, nor is staff time to send it
If you had read ETrade's fine print you would know that you get the interest. I was going to post the URLs and interest rate, but they are too long for a lynx line, and netscape is acting up on me. Javascript is getting in the way. Go to their web site ETrade and prove me right, it is easy, and the reasearch will do you good.
Right, inside the us there is no limit to encryption use. It is gaurentied in our constitution that we can secure our comunications. Not to imply that they won't try to get around this somehow, but the reason the laws applie only outside the US (as if there is jurisdiction) is it sortof gets around the problem for those who want to take away out rights.
Accually the reason that the 6th grade reading level is used is that with english you don't really gain anything with higher levels. By 6th grade you can read. Granted you couldn't read a medical text book intended for grad students, but then again those students can't understand computer text books like I can. A lawyer deals with complex language all day, but he can't read either the above, and neither the med student nor I can deal with legalise. (I can wade through it and figgure out, but it isn't easy)
Byond 6th grade you specialise as needed. Your vocabulary is good enough that you can read.
Interestly enough, in Japan the news appers are written at the 9th grade level, and despite the 20 hour a day study habbits less japanise are equiped to handle newspapers. This is not becuase the japanise are stupid, but because the written language there is so much more difficult.
could someone with wrist pains tell me if these help? I can't get away from the keyboard at work, but if I could check my home email and read usenet (there are good groups left, but you gotta know killfiles) it might save my wrists enough a bit.
I'm not calling this carpil tunnel, cuase as all/. readers should know by now that there are many other causes of wrist pain.
.9 watts of power @ 600 mhz! Low power is the key for laptops, and the ARM beats the x86 or just about everything else. Linux will run just fine (I prefer netBSD, but the difference isn't that great)
If Apple would put three buttons on their laptops I'd go for that as a second choice. I know the ARM better though as I program on it all day at work.
Your somewhat incorrect there. Appletalk is not 300kb/s, localTalk is. Apple designed their own signaling/cable system for the early macs, but ALL current macs can use appletalk over ethernet, at ethernet speeds. The new iMac cannot do the old localtalk, AFAIK all others can.
I use netatalk and samba to deal with the mac and windows machines at home, both work well, and the user has no reason to care which they are using. I've never tried sharing printers so I don't know if that works.
Re:Gone are the days of remembering ip's.

IANA Deploying IPv6
·
· Score: 1
Your not alone. I too remember ips. When your working in a lab that changes hourly. I know all the ips. I don't even have a DNS on many networks. I make up IPs as I see fit. We have to firewall the lab, to prevent my from messing up the rest of the company, not to keep intruders out.
I don't know if it can work for you, but I found in all my dorm rooms that while floor space was at a premimun, there was plenty of space in the upper half of the room. Many dorms have 10 foot ceilings (not all), and that means typically about 5 feet is wasted. Build some shelves. Put the computer above the refridgerator. (careful of cooling issues of course)
I tried the week vacation, no typing. Got back to work, and was pain free for all of 15 minutes. Which isn't to say the rest wasn't good, only that it didn't help me.
Can we say ground loop anyone? Don't run cat-5 from building to building, it was never intended to do that, and so while it might work you are asking for trouble, such as destroying your computers.
The orginial 10base5 ethernet was designed to run builing to building (if the trnascivers will do that I don't know. For that matter, I don't know where you would find it as nobody has done 10base5 since the mid 80s at least, other then to fix the old already installed systems.
Best bet: fiber. Glass is immune to a lot of electircal probelms, and the cables are cheaper. You have to look, but you can pick up some cheap 10baseFL cards for nothing, and linux supports the ones I've got.
Please folks, if you don't know how to prevent ground problems don't run wire from building to building. Glass fiber is cheap enough, and it avoids a mess of problems and won't destroy your computers.
I don't care if my computer advertises SEARS or the like (better not be porn or mind rot like tobacco/alcahol), So long as it doesn't interfier with my reading of the BIOS POST messages (not that they really matter). Generally POST needs half the screen, leaving half left for an ad. I don't care as the comtpuer isn't booted anyway, and with the ad in there the comptuer can be cheaper for the same quality.
Besides, the only time I reboot is power failure or new kernel. For the former my monitor isn't even on, while the latter doen'st bother me either, after all the time it takes to check 128Mb is plenty long for any advertisment.
Of course I'd hate it if it lenghtened the already too long boot process, but that it shouldn't need to.
Doing it right the first time of course isn't that easy, but once it works, don't break it. It must be possibal to run a 24x7 site for an entire year, while stuck on gilligan's island without any way to contact the rest of the world including the site.
Nasa has comptuers in buildings where at any moment deadly (a few seconds from a small leak and everyone in building is dead!) chemicals are around. Do you think that their IS wants to touch the comptuers? Not unless they first send everyone else home and empty those tanks. If it wasn't so heavy they would probably insist on space suits too.
You decide a year or more in advance how much bandwidth you will get. Then decide how many customers that will support, and you don't allow marketing to sell to any more customers. Thats right, you refuse to allow more onto the system. Marketing can deal with this if you make them, and long term satisfaction will go up.
Once you know how much bandwidth you will have, you make sure you have comptuers that can deal with it. Mainframes have been doing 24x7 for years. Unix is very close to matching that (with Sun's redundant hot swapable system perhaps better, not that sun is the only chioce) I have seen tripple redundant systems with a polling mechanism where if one comptuer gives a different result it is shut off. Guess what: none of this is cheep. Thats right, doing buisness on the internet in volumn isn't cheap. Spend the money on system that will stay up, and enough power that you don't run out, and you will run 24x7. There are plenty of companies that make equipemtn that is ment for this use.
Last, and foremost: hire system administrators that have proven they can keep the systems running 24x7, and pay them to do so. These people are older, in their 50s or so. Hire thebest of the expirenced, and then give them a deal: you pay them to keep the systems up there or not. They should soon find a paycheck arriving every two weeks, with only a few hours a month work.
Remember, design the system so you can run it from Giligans island (no access by you) without your boss realising, and you will do fine.
Of course reality is that you do have to replace crashed harddrives, but with RAID-6 (raid-5 plus more redundancy, raid-6 isn't officialy defined) that is any time. You do need to buymore backup tapes once in a while, but automatied backups are the norm in 24x7 enviroments.
. I'm pretty sure you can do the opposite, and telnet to the box to access it's ports. What? You mean that people use terminal servers for other then accessing consoles? We have several 64 port terminal servers in out lab, nearly all the equipment we have has a serial port on that is connected in turn to a terminal server so we can telnet to the console.
We build our own hardware, and let me assure you that working serial port consoles are first on the agenda for those who write the prom code. We can't imangine debugging without printfs that go directly to this serial port. (Yes, we have heard of source level kernel debuggers. We have been paying $$$ for them for a few years. rumor has it that two weeks ago someone finially got it working.) Even if we did have debuggers, the serial port is the perfect place to controll things when your network hub dies (the hub is built in so that several processors can talk via ethernet internally. Or at least that is an explination I think the NDA allows me to give)
In short, you can use a terminal server to access console ports. I didn't know they were used for anything else.
If you have two linux machines next to each other, what you can do is use null modems to connect the serial ports togather. For resets, you can wire a relay to the parrell port and the reset contacts on the motherboard. When one needs a reboot log into the other and execute the commands to do so.
Of course with as stable as linux is, you will probably forget you have that ability, spend 2 weeks trying to remember where the broken machine is, and then reboot it from the console.
If he could make a spell checker that can figgure out what I mean with some of my worse mispellings (I'm not talking about teh->the I'm taking about worse things. speaking of teh though, can it figgure out I intentially mispelled that) he can make a fortune. I know there are 100 or so people reading this who are willing to donate to the cause of getting me a good spell checker.
Too bad if any exist they are not really workable.
In case you are not aware, guns are baned from school grounds in the US, and more then 10 other guns laws were broken in both those cases. Those kids have already proven willing to break gun laws and kill others, so putting a few more words down on paper won't solve the problem, it will just take guns from the law abiding.
Amendment IV The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no Warrants shall issue, but upon probable cause, supported by Oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized.
Looks to me like I have the right (in the US) to secure my papers. I think that the court would agree that papers would cover anything on my computer which I could easially print.
Now with a warrent they can search my papers, and I suppose I have to give up my key then, but not without a court warrent.
double encryption should NEVER lower the strength of encryption. That would mean the encryption is insecure. OTOH, it doesn't have to increase the strenght.
In the case of DES, there is a known attack on double encryption that makes double encryption equal to single. Tripple DES (where you encrypt with DES three times) is more secure. Typical implimentations of tripple DES only use two keys, so you only have two keys to break. Not all tripple DES uses only two keys, some use three. There are also several different ways to apply this. (Typical is to encrypt with key A, decrypet with key B, and then encrypt with key A. Not the only possibal one)
Please, before you comment on issues of encryption you owe it to everyone to read Bruce Schinder's work Applied Cryptography
