Section 2.5.5.2 of RFC-4291: IP Version 6 Addressing Architecture
describes what in IPv4 terms one might call a super-network prefix that does exactly that: map the existing Internet onto an infinitesimal corner of the huge IPv6 address space.
Lessee... they raise the possibility that kids will view porn on the Wii and then call it a "smear campaign?" Looks like somebody's got a sense of humor.
I'm just a summer intern right now too, and in the duration of my 12 week internship I will have started and ended (or come darn close) my training for a private pilot certificate. Granted, I don't have any money or time left over to do anything else, but with planning and discipline, it's very possible.
With regards to mileage, a typical single-engine plane has a cruising speed of roughly 130 mph, and you could expect to burn fuel at 6-8 gph. That translates to something like 19 mpg. Not great, even compared to mediocre cars, but then again, not vastly worse than a minivan or SUV that you might take on a cross-country trip, and a heckuvalot faster.
What about making the system fully automated and triggered with a watchdog timer? If the moon-based genetic vault doesn't receive a reset signal within some amount of time that would, for example, allow surviving Earthlings to get a transmitter working again, it would start to grow, raise, and train our replacements... or maybe it would just start a bunch of small shell scripts instead.
XOR is also very handy for computing parity. If you think of this bitwise as applying one bit to another by way of the exclusive OR operation, then the application of a 1 toggles the bit to which it is applied, and a 0 doesn't.
Looking at a serial example, we start with a 0 if we want EVEN parity or a 1 if we want ODD. Then we apply each data bit against that in sequence using XOR and the result after every operation is the parity bit for the bits examined so far. So with EVEN parity (0) and the octet 0x6B (01101011b), the result is a 1 after three holds and five toggles, or rather the value which must be appended to the octet such that the number of 1's is even.
RAID5 is striping with parity, which means (roughly speaking) that each nth stripe is the XOR of the n-1 stripes behind it. In this way, any one stripe can be regenerated by combining the others... with a whole load of XOR's.
Would it be overkill for you to get a low-grade shared hosting plan that included email? If not, then you should take a look at DreamHost. Their cheapest plan is $8/mo and includes one domain name registration (1yr), 20GB of space, IMAP, webmail, and a bunch of other geek-friendly things that are pretty spiffy, but that might not be as relevant to your needs.
I do not work for DreamHost, but I have been a very happy customer of theirs for several years now. They've got stellar customer service and tech support, and they are constantly improving the feature set of their plans. For example, this month I got a notice that the disk space had been quadrupled and that all accounts now support custom DNS.
...it's much easier than having to tab 30 times till the correct hyperlink is selected in my browser...
Ah ha! But if you were using Firefox (like any self-respecting Slashdotter) you would know that your browser will take you directly to a link simply by typing the first few letters of the link text. Read all about it.
Granted, many sites implement links as images which brings us right back to square one, but there are enough situations in which the Find As You Type feature works that it's worthwhile to know about.
I'll do you one better. Take some voice-recognition software, a speech synthesizer, hook up ALICE in between them and let her take your unwanted calls.
It's a jet? Yes. It uses Jet-A? No. Please refer to their website. FYI, the respective specific gravities of gasoline and kerosene are 6.82 lb/gal and 6.15 lb/gal.
I agree with your premise, but I would like to add my own two cents. Irrespective of a particular computer's ability to protect itself (with or without special software) something like a hardware firewall is just good engineering. It's a low cost device that is capable of protecting an entire group of computers in a simple yet effective way. It uses resources in way that is effective.
Apologies for blowing my own horn, but there are those who may appreicate this.
Those times when my computer savvy permits me to avoid BS like "we don't support routers" are among the sweetest. In truth, a Linksys or DLink (or whatever) gateway plugged into your cable modem looks strikingly similar to a regular computer to the ISP (let's hear it for layering and protocol standards!).
I was supervising the transfer of Comcast internet service when my girlfriend moved earlier in the summer and several things happened. 1) The cable modem which we had brought from her old appartment worked fine as soon as we plugged it in at the new house. It synced right up, and everybody was happy until the subcontracted cable "technicians" arrived to "install" the service. Nope, sorry, it doesn't matter if it's working now we have to give you a new unit. That leads to... 2) When all the busy work was coming to an end and the light at the end of the tunnel was approaching: "Now we need to plug it into your laptop so that it will sync. Give us the laptop." Me: "No you don't need to do anything to this laptop. Just plug the ethernet cable into the back of that box up there." Them: "Really, this won't work unless you let us screw around with the laptop." Me: "Thank you. Good bye." Them: "<confrontational> <gruff> <self-important> <storming out>". 30 seconds later the modem finishes booting up, it locks onto the network, the DLink box grabs its info, and everything is working just beautifully. On the bright side their unprofessional behavior and a few phone calls to Comcast customer service resulted in an extension of the introductory price: a full year at $19.95.
Once again, I am so happy I know a thing or two about computers. But I really don't know sometimes how most of the rest of the population manages to slog through all the crap out there.
I've been using TB as my primary email client for some time now and would like to comment on your spam issues. Just for the sake of context I use five different email accounts and receive over 1000 spams per month on average. However I have never used SpamBayes so I am not in a position to make a direct comparison.
1. Training: For the initial training I waiting until a rather large number of spam messages had accumulated in the trash, then selected all of them and chose Message->Mark->As Junk. This, of course, works best if the folder is local. Following that I chose several large folders of personal correspondance (both from and to) and chose Message->Mark->As Not Junk. Judging by your comments it seems possible that you have not found these two menu items but rather have been relying on the junk toggle column in the main message list.
2. False-positives/false-negatives: I have a little trouble reconciling "I do have to check my 'Possible Spam' folder every few days and see what's in there." with "...and don't like the idea of having to check dozens of spam messages to make sure a good e-mail didn't end up in there.". There must be some distinction with SpamBayes that is lost on me. Be that as it may, I have found that operating a mostly-trained system is relatively headache free. TB is set to move suspect messages (i.e. "Possible Spam") into a Junk folder locally that is common to all five accounts. Every few days I scan the list of suspect spams for false-positives. Since my eyes are sensitive to the exceptions the misses are easy to spot and fix with the junk status toggle. False-negatives are even easier since there are rarely more than one or two per day and they are naturally left in the inbox.
I currently have over 3,700 spams sitting in my trash folder at the moment. I suppose that I could generate a training.dat file with info on those messages to which anyone could add their own non-spam data (which is important to reduce false-positives).
The difference that you mentioned between "Maybe Spam" and "Spam" is a bit shaky since I imagine that it's only a matter of liklihood. You should still keep an eye on the Spam folder for false-positives.
Um, isn't less movement bad? Blood flow is good. Variety of motion is good. No motion is not variety. Standing up and stretching every fifteen minutes is great.
I was watching the CNN coverage this morning and would like to point out that their space correspondant (another O'Brien) did in fact point out that Mach 25 represents eight times the energy. For a rocket-propelled craft the need to store and release more energy generally translates into the need to carry more fuel.
Sorry if I seem snarky but I feel that many of my fellow posters are missing the point of this discussion. At issue is not necessarily the question of exactly which things should be written in assembly code (or not) but rather that the experience of learning to program in assembly is a valuable one. I noticed an improvement in the overall quality of my code during and after taking the assembly programming class that is still required for computer science as well as electrical and computer engineering majors at CU Boulder (I am one of the latter).
The debate about whether assembly code really provides an appreciable gain in performance in certain areas, or if the gains realized through assembly programming are worth the costs in time and flexibility, is an important and necessary debate. It is not the most useful discussion that could take place at this time however.
Seriously folks, I don't mean to get embroiled in the issue of semantics, but there are all sorts of devices in which their OS is lightweight enough to reside in ROM. If the boot code never hands control of the system off to a secondary module (loaded from a disk, for example) how is it not the OS?
I'm curious about the grounds on which you make this claim. It seems that you intend to make a point about the series/parallel configuration of the batteries but it is not at all clear what that point is.
So as not to appear hasty or impatient, I'll give you an opportunity to go into more detail about those "extreem inbalances".
Theoretically, if two batteries rated for the same voltage are connected positive-to-positive and negative-to-negative, no current will flow between them. In practice there may be a small difference in the potential at the positive terminal of one with respect to the other which would result in some current drain. At some point however the differential would vanish due to the discharging and current would cease to flow.
I propose that batteries in parallel are fine as long as you replace them simultaneously.
In all seriousness, the university may only have the right to grant access to your records to a very limited number of people without your consent, not including your parents. The Family Education Rights and Privacy Act (FERPA) is the law that governs educational records. From what I understand, the student and his/her parents share information controlling rights until the student turns 18. After that time, all rights are transferred to the student.

Nevermind, I get it now. It's that the problems are valid, not the lists.
*searches for coffee*
Well, either the lists are valid or they contain bad information. Which is it?

Ah, so... 2.95 feet per metric, eh? Good to know.

less body movement is still a better replacement.
