    Scariest ride in my life was in a taxi going down Broadway in NYC.

The scariest ride was in the army hitching a ride on the mail truck back to the field. The driver was a speed freak (methamphetamine) who called himself "Kowalski" and was always trying to beat his personal best time. I had seen the movie Vanishing Point. Now, I was in it!

    Well, you could use patent 4,809,168 which AFAIK is in the public domain unless IBM convinced the Patent Office to allow IBM to retroactively pay the the maintenance fees. It's the patent referenced as HOS89 in this RCU performance paper. But I'd ask IBM for permission first because, one, Paul McKenney was gracious enough to cite that patent, and, two, because it doesn't hurt to ask the don for permission and show a little respect.

  8. New SwissTool model "Spirit" on USB Swiss Army Knife · · Score: 2, Informative

    coming out this spring or summer. You can see a picture of it here. Nothing about it at victorinox.com which is pretty lame for info on their own products. Nothing on swissarmy.com even though they have the the SwissTool Spirit in a printed brochure. The nice thing about SwissTool is the bit tool. The attached tools in a multi-tool are pretty much useless as far as I am concerned due to the awkwardness of using them. The bit tool, which uses standard 6mm or 1/4" bits, pretty much solves that. The redesigned bit tool for the Spirit not only looks like it could take more torque on the right angle socket but you could use a short bit of hex stock to make it a T handled socket tool. Sweet.

  11. Re:I predict on SCO Complaint Filed -- Including Code Samples · · Score: 2, Informative

    In my admittedly non-legal opinion, just because a certain OS technique was discovered and perfected on a UNIX-derived platform, that shouldn't mean that IBM loses the right to bring the same technology to any other platform they're interested in.


    That part of what the lawsuit is about, what the contractual meaning of "derivative work" is. Except one of the techniques, RCU, was actually first developed on a mainframe operating system, VM/XA in the mid 80's. I've pointed this out before on Slashdot. What's really spooky is that the VM/XA functions are virtually identical to the independently redeveloped Linux RCU functions. HCPMPDFR was to schedule an asynchronous piece
    of work after every processor has gone through a checkpoint at least once. The Linux function is call_rcu() and uses the term quiesce state instead of checkpoint. HCPMPDLY was to delay a thread of execution until every processor has gone through a check point at least once. The Linux function for this is synchronize_kernel(). The mainframe patent is 4,809,168. The Sequent/IBM RCU patents are 5,442,758, 5,608,893, and 6,219,690. I'm writing authoritatively here as I was the original developer of the VM/XA code and one of the inventors on the mainframe patent.


    I'm not sure why IBM doesn't have the RCU claim knocked off the lawsuit since it is clearly not a Unix method. It could be it's not worth the effort since they still have to deal with JFS, NUMA, and SMP kernel stuff in the suit. It's also possible that IBM doesn't want to diminish the value of their RCU patents since the mainframe patent was allowed to expire and is in the public domain AFAIK. McKenney and Slingwine know about the
    mainframe prior art since I've informed them of it a while back. I will say that they were remarkably gracious and good sported about it. Also, I have to commend them on their publicizing and promotion of RCU without which we wouldn't be discussing it now.


    And what bugs me is that despite all this publicity that RCU has gotten, when I mention it while looking for programming work, no one has a clue what it is and thinks I am babbling total nonsense. Which it probably is. It certainly doesn't help in finding work.

  13. Re:Where to buy extras? on Which Screw Goes Where? · · Score: 2, Informative
    The PC places will charge you about a dollar for a few screws of questionable quality. You are better off going places that specialize in them and buy in quantities of about a hundred. It doesn't cost that much more and you will always have spares.


    Try here, here, or here. Also here for torx screws as well as regular machine screws if you can figure out how to navigate the site. Has every type, size and style imaginable. You can even get black oxide coated for your black cases. A little patience with this guy, he's not the fastest shipper there is. And Ebay of course.


    For hard drives you want 6-32 screws. I recomment getting them in 3/16", 1/4", and 5/16" lengths so you can deal with any mounting situation without having the the screw too short or too long to screw in without hitting the drive's pc board. Case screws are 6-32 except Lian Li cases which take M3-6 (metric, 3mm dia. 0.5 thread pitch, 6mm long). Floppy drives and CD/DVD drives take M3-6 also. Basically these two sizes will take care of everything though you might find the odd disk enclosures taking 4-40 screws which might look like M3-6 if you aren't familiar with them so be careful. You don't want to cross thread some expensive piece of hardware. Fans will take a 8-32 screw and nut, or a 10-32 thread cutting screw if you don't want to use those cheap fan screws the pc places sell.


    There are different styles of screw heads. Hex flanged w/ phillips which is the case screw most of you are familiar with. Other head styles are button head which is rounded, pan head which is wider, and truss head which is even wider. Truss head screws look nicer and the wider head deals with mounting slot opening better. There are other styles as well. Check the sites I listed for illustrations of styles.


    There are different drive types. There's slotted which is the worst since it's easy for the screw driver to slip out and jab some other component in you pc. Phillips which is a cross tip, tends to cam out at high torques but you shouldn't be using high torque on anything in a pc. Hex which is hex shaped naturally. Socket which takes a hex (allen) wrench. And torx which is hexalobular (that's what the ISO standard calls it). Torx has the best feel for torque control which lets you snug up those screws without over torquing them. Plus it looks cool.

  14. Re:Location, experience, etc... on Unemployed? Why Not Start a Software Company? · · Score: 1

    Typecasting is pretty horrific. I've been trying for 10 years to get out of sysadmin back into software development. The sysadmin job was just supposed to be temporary to learn unix. When you point out to a prospective employer that you used to work as a developer on a multi-processing kernel, they look at you as if you were speaking Martian because that wasn't your last job.

  15. Several different issues here. on 'Just Sleep On It' Solves Tricky Problems? · · Score: 1
    One is the fatigue factor. If you are sleep deprived, you just cannot concentrate enough to effectively solve the problem. More experienced programmers recognise this and just take a break at that point.


    Another is the learning/forming memories problem which has been discussed here before. 8 hours seems to be the magic number here.


    The last is the most interesting. It's where those solutions come from. What part of the mind is involved. It's not the logical train of thought part of the mind, and it does not communicate verbally. It's rather subtle and where the idle/sleep part comes in. If you're in deep concentration you may miss that flash of intuition. But you need that intense concentration up front to communicate the problem to that non-linear part of your mind as far as I can tell. You don't get so many intuitive flashes for problems you don't obsess on.


    The other interesting thing is since that communication from the non-linear part is non-verbal, the solution may be misinterpreted. Or it could be it was just wrong, it's hard to tell the difference. This has happend to me at least once, got it completely backwards. I find it helps to apply formal methods to your idea to sanity check it. A form of error correction I guess. It will also help you understand it later on when your intuitive hunch wears off and you revisit the idea and have no idea what you were thinking of when you had it.

  16. EPC lookups for what? on Verisign to run National RFID Directory · · Score: 1

    I imagine that stores would already know what rfid's they had in inventory. So, it's not clear why they would need a EPC root server or who actually would be using this service. I'm more worried about the stores forgetting what they have in inventory vs. what they sold, given how good companies are at correctly maintaining databases and backing them up. Could make for some interesting store exit scenes. Make sure that you have all your receipts for everything that you are wearing.

  17. Cache contention with Hyperthreading on Hyper-Threading Explained And Benchmarked · · Score: 4, Interesting
    Threads using hyperthreading or SMT share the cache. This can be a problem if the threads are from different processes and not sharing memory. Your cache is effectively halved (with 2 hyperthreads). On the other hand, it could be a real benefit if your threads were from the same process sharing the same memory. You don't have the cache thrashing which could occur on a multi-cpu system. Since cache hits can really kill performance, this could be quite a performance boost.

    To really exploit this, you'd need gang scheduling in the operating system. But it's unlikely that SMT would remain around long enough for any efforts to exploit it to be feasible. CMP with separate cache would likely take over before then since it would behave more like separate cpu's from a performance standpoint and thus offer more consistent behavior.

  18. No Return Policy on The Hidden Costs of Bargain Electronics · · Score: 1

You're stuck with the original mfgr's or distributer's warranty and the hassle of dealing with that. Unless of course you want to pay for one of those overpriced "extended" warranties.

    Actually more like 16, and then switched to sysadmin (which was supposed to be temporary dammit! WTF is it with the only last job counts as far as skills go). Most progammers have no idea what is involved in system support. It's a major pain, which is why I've been trying to get back into development. Trying to explain to a user why something isn't as simple as when they just fool with their own machine is equivalent to a programmer trying to explain to a non-programmer why a quick and dirty script isn't generally applicable. You have to do error checking, make sure it applies generally not just specific cases, and is thoroughly tested. Same thing with system administration. You have to figure out how to make something work for all users, and above all else test the hell out of it before rolling out the change. Last bit is important because unlike programmers, sysadmin customers know who you are and how to find you if something goes wrong.


    And yeah, there are BOFHs. Even sysadmin run into them themselves if the organization is large enough.

They even have USB/Firewire combo and Firewire2 (1394b) bridgeboards. I got my Oxford 911 chip based firewire bride for an external case w/ mobile rack for hot pluggable hard drives. SATA is supposed to be hot pluggable but I have concerns about the SATA connector duty cycle rating. It seems to be a little low to be using it for removable drives.

  23. Re:SATA anyone? on New Low Cost DVD Burners Hit The Streets · · Score: 4, Informative
    I don't think there's enough of a market to justify making them from the OEM's perspective. When they do, they will probably just tack on a bridge chip which is what some of the hard drive OEMs are doing. You can get a SATA/PATA bridge board now for about $20~$25 which will be less than the premium charged by the drive makers when they eventually do come out with them. If you do that, make sure the SATA/PATA bridge chip supports ATAPI as some of the early bridge chips only supported SATA for hard drives. The Silicon Image SiI 3611 supports ATAPI. Make sure your SATA controller also supports ATAPI, same issue there.


    Addonics makes such a bridge board here. Note their comment about compatibility. Also, AMS makes two styles here that use the 3611 chip according to their data sheets.

    Skipping commercials is nothing new. What's new is that suddenly the advertizers "noticed" that commercials weren't always being viewed. To fix this "problem" the following will have to occur during commercials: disabling fast forward/skip on DVRs, disabling the remote control, locking the doors on bathrooms and refrigerators, etc...


    What's actually changing is that advertizers are becoming aware of the impact of technology. Their initial reaction is negative but will become positive when they realize the control it will give them, particularly interactive TV. You will have to have viewed the commercial in order to supply the correct prompts to view the rest of the program. Welcome to the future. Welcome to hell.
