Well, this answer isn't Mac specific, but what you are looking for is single system image (SSI) clustering. There is a project for Linux sponsered by HP that does this -- you set up one box (preferably with a shared drive -- firewire or scsi), and network boot several others connected to it via private high speed etherenet interconnects. It then runs special code that lets process on one box migrate to un-loaded boxes, so that the whole group of them will look like one big SMP system. See openssi.org, also check out mosix / openmosix.
linuxdevices has a fairly comprehensive list of what is available. Unfortunately, you'll be disapointed. Your best bet might be to get an older Compaq iPaq and put Familiar on it. But the Compaq's don't have a built in keyboard, and the SD slot might not be supported under Linux. To get a device you'll be happy with, it will cost from 300 - 800 dollars -- i.e., one of the Sharp Zaurus lines. They have built in keyboard, good display, sd & cf slots, etc. But support from Sharp is lacking -- they keep on discontinuing models, they totally screwed their community (by pulling the plug on the community development site). Of course support from zaurususergroup.com is good. But again, they are out of your price range.
Or, you could hold out till Palm comes out with their linux-based distribution. You might even be able to upgrade to it on existing arm/xscale based palm devices (which again might be out of your price range by a couple hundred).
Then don't cancle, just stop paying the bills. Some DSL providers let you auto-pay by credit card, just cancle that particular card (at the end of your dsl contract of course). Then you have a better chance at pleading dumb. (i.e., do a closet cancle)
One safety issue with this: if you typo the destination directory, then you will be untaring in the original (source) directory, which will wipe out any file larger than tar's internal buffer size. A slightly safer version of this is:
tar -cf - . | if cd/mnt/hdb; then tar -xf -; fi
Now, if/mnt/hdb doesn't exist the second tar command won't run.
One thing to note which I've seen a lot of people get confused about. There is a line on the 1040 form for the amount you were refunded from the state last year. Many people fill out this line. However, if you took the standard deduction last year (i.e., you didn't itemize & include state income taxes as a deduction), you are not required to fill in this line. Check page 20 of the 1040 instructions (pdf on irs.gov), section titled "Line 10"
Beyond the standard mortgage, property & state taxes, and charitable contributions, you can deduct: * Gambling losses (add up all those state lottery tickets) * Losses on investments (you can only deduct actual "realized" losses, i.e., after you sold stock. But don't forget to account for realized gains also.) * Some medical expenses -- this is somewhat limited * Casualty losses -- theft, fire * Union dues. * Out of pocket work expenses -- be careful on this, for example if you bought a new computer & dsl connection and use it for work only part time, you won't be able to deduct the full amount. But if the job requires you to have it and they don't pay for it, then you may be able to deduct it (check the tax instruction booklet). More common is things like company uniforms, business lunches, etc. Note that you get a "standard" deduction of a few thousand dollars. You can either take that deduction of the total from items such as in the above list, but not both. So if you add up everything and it comes up to be less than your standard decution, then the standard is all you get. Download the pdf instructions for form 1040 from irs.gov (not 1040a), and look for the instructions for Schedules A & B. Also do a google search for "common tax deductions" and see what applies.
It's in the instructions that come with the tax forms. I'm not sure if you can round every line in your calculation, but you can round the final result. Go to irs.gov and grab the 1040 instructions pdf, search for rounding.
Actually, all you need to do is define what data is "loosable" v.s. "need to keep". For example, I've got a metric boatload of iso images for various Linux distros, but if it all dissapeared I can always re-grab them. However, my cvs archive and email & home directory all fit within a few gigs. Also, one of the uses of a large storage server is to have room to grow in the future. So go ahead and build it, as long as you've got the means to back up your critical stuff (and at least directory listing of everything else) you should be fine.
Based on your logic, if you put a bunch of money in an S&L account that isn't FDIC insurred, and the president of the S&L decides to squander your life savings on booze, parties and yachts, then your money hasn't really dissapeared... it has gone to the liquore and yacht manufactures who in turn pay their employees who buy consumer goods & services, some of which comes from the company you work for and ultimately ends up in your paycheck.:-)
In theory, this is simple. You have an encryption algorithm set up as follows: The data is encrypted using key "A", but can be decrypted with key "B" (similar to RSA). However, in this case "B" is computed via a function that has inputs "A" and "C", where "C" can be an one of a very large keyspace. And, "A" can't be determined by "B". This allows you to have a unique "B" decryption key for every player. In other words, you have: * encrypt(A) * decrypt(B) * B = hash_of (A, C), for any valid value of C * C = one out of a large keyspace (allows unique B for each unit) * A cant be determined by B
Since key A isn't on the individual units, it is as secure as the manufacture's internal security policy (so it isn't likely to be compromised). And the decryption key B is unique for each player.
Now, I don't know of any methods that can produce the above results, or if this is what AACS uses, but I don't see it being impossible either (just like asymetric encryption wasn't do-able until RSA came along).
Well, in the case of the safe, you'd have to forget to "weld the back end on", and forget to secure the back door on the building, and leave an opening in the side perimeter fence, and leave the attack dogs tied up. This is what's meant by layered security. You don't just add three more locks to the same door, you instead add & secure more perimeters. The way you'd do this on a web server for example is to have the outside firewall direct requests to an inside box, which interprets the queries and then re-issues the incomming requests (after validation & sanitization) to another box that only it has access to. Hopefully each box is running a different os. Also, the internal web server should query a database server on yet another host, with a firewall between them. That way your database server is 4 layers away from the outside user.
To continue this line of true stories...
When I moved a few years ago, I had rented one of those self-storage units. The gate to the property was controlled by a push-button lock, each customer was issued a unique code. My code quit working three days after I rented the place, so the site manager punched in his code to let me in. It was 1 2 3 4 5.
I never did find out if they fixed my code, I just usd his whenever I needed access.
An old saying -- Money ain't the only thing that has value.
Everything has an opportunity cost. If you spend your time watching a movie, you have to give up reading a book during that timeslot. Building your own myth tv box means that you won't be able to watch that movie. Since time is a "fixed income", you will always be giving up something to do something else. So, as long as what you're giving up (i.e., laying around watchin infomercials) is less valuable than what you'd get out of doing a particular project (i.e., designing your own pvr), then that is a good tradeoff.
Actually, I take a slightly different view of why RMS is "wrong", and one that he would probably agree with. When you refer to GNU, the image brought up is that of a complete system run by free software, and encourages the use of free software on top of that system. Whereas Linux carries the connotation of having a free toolchest to act as a base, that anyone can use however they see fit. Kind of like having a bunch of free land available, but people can build private houses on that land. This kind of carries out to what we see, for example Debian GNU/Linux usually isn't used to run proprietary Oracle, but Redhat Enterprise Linux is.
Look at mini-itx.com for some ideas. More specifically, check out the via epia series motherboards, they are very small, low wattage (therefore no need for a big fan), and have video out that can work with linux (again look through the forums on mini-itx.com for details). Personally, I would set up one of these with an 802.11g card and network boot.
If it's mostly just adware ad not viruses, then boot up into single user (i mean "safe") mode (hit F8 on initial bootup, and select "safe mode with network support"), and log in as administrator. This will at least keep the adware startup scripts from running. Then, run ad-aware and spybot. Finally, take a manual look at the startup fields in the registry -- run regedit and look at the key "HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/Windows/ CurrentVersion/Run". Also, there's a bunch of startup fields that are kicked off by IE. The best way to find them all is to grab CWShredder (which is designed to speciffically handle Cool Web Search, a particulary nasty bit of malware). It has a "report" option, run it and it will display all your starup registary keys, both under the...windows/currentversion/run and the various IE startup / helper objects / toolbars -- kill anything that looks like it doesn't belong. Then, open a command window (cmd.exe), cd to/"Program Files", and do a "dir/od" (order directory listing by date). This will group the most recent program installs towards the bottom, to make it a bit easier to identify possible bad ones. Look at the exe files in there, and do a google search using unrecognized program names as keywords (along with the keywords "windows" and "spyware"). Once things are cleaned up, reboot normally, pull up the tasklist and again lookup any program that you don't recognize. This process has worked for me everytime so far (takes about an hour or so once you get into the swing of it). Good luck.
Actually, it was sold as a two disk set, one was a standard DVD that will work as expected. The second disk was DVD data format, containing a WMV-9 format version of the movie in high-definition. The box did say that it was a windows media format disk, but it didn't say you also needed another application downloaded or a net connection.
Basic summary, as long as most people have regular dvd players, movies will still be sold in that format. So you'll only have a problem on these one-off products that try to do something different.
Not only keep up on patches, but also seperation of services. Your web server should run under a chrooted environment at minimum, as a non-privlidged user. Any files that doesn't need to be written to by the web applications (including html and cgi files) should be owned by a different user id (and not world-writable).
The most secure setup I've come up with is setting up Usermode Linux (or Linux Vservers) so that I have a bunch of virtual OS's running, each with only the bare minimum libraries that are needed to support each one's dedicated services (got one set up for bind, sendmail, apache). Each virtual OS session has multiple network interfaces (one is set up as an "internal" network only, another is set up to accept packets redirected from the outside vi iptables rules). Any config/data files that I need to update periodicaly (such as the html files for the web server process) live in a partition on the parent server, NFS exported read-only to the appropriate session's internal virtual ip address. Any files that they need to write to are symlinked to a locally-owned filesystem. Log files are set up append only (still working on this, I was thinking of using one of the user-space filesystems to impliment this feature, or checking if selinux can handle that).
A similar problem can arise if you are using a tape library to hold all your tapes -- an atacker on the system can still delete your data. The best solution would be to have a seperate secured server handling your backups, and that server can either have a tape library attached to it or a bunch of disk storage (tapes having the advantage of being easier to take offsite).
I'm pretty sure that was the purpose of having the hard drive attached via usb, otherwise the poster could have mounted the drive internally. Also, keep in mind that a backup via tape drive is also vulnerable if you leave the tape in the drive after the backup:-).
Simple, just add a rule that if you don't log in for a week, check the obit's in the various online local newspapers. If both conditions are true (name found in obituary, and no activity), then activate.
If you have access to a hot water supply (or cold water and a microwave), then pick up one of those coffee presses (Bodum makes them). Then all you need is your beans, a grinder, and a bottle of dish soap to clean out the press after your done. You get a different flavor, but it is a bit better than standard office coffee.
From what I understand, FedEx didn't pay to be featured in Castaway. The producers did have to go to FedEx for permission to use their logo, etc., since they wanted to give the film an added bit of realism. But they purposely refused to take money for it, because they didn't want FedEx to become another "creative partner" in the film.

I've seen fm transmitters that plug between the antenna & radio, so that it gives a clear signal even if there is a local station on that frequency.
Another option would be to wire a small amp into your car speakers & set up a switch box for your portable.
