  1. Tag a box of stuff. on Using RFID Tags Around the House? · · Score: 1

    I've been toying with the RFID idea also. So a mysql database of all the tags and the items. Put items in a Contico with a tag, and hierarchically log whats in the box. The database is keyed on items, add a digial picture + description/audio clip. When you are about to search for that item that you know will be in the last spot, consult the database, find the Contico take the item out. Later, a quick scan of the item will reveal what box it needs to go back into. Something like that.

  2. ethereal? on What To Do With Old Laptops? · · Score: 1

    You can put a 10/100 hub on your conn and tap packets leaving/entering your LAN. Even better would be a GUI for a quick look at current utilization and port activity. Perhaps also a top 5 ip addrs knocking on the door. With a second NIC you can policy data coming in but these laptops prob don't have enough power for that.

  3. Algol68 on Are C and C++ Losing Ground? · · Score: 2, Interesting

    Strong typing. Garbage collection. Native code generation.

    Lack of OO and a current up to date machine code generating compiler would be a detriment though
    to a rollout anytime soon of this old language.

    My $0.02 is that the air density computation came out wrong for whatever reason. Result: A very lean burn flaming out #2 and causing #1s request for more power to spin out to high RPM with not much to show for it. One passenger inside @the port side said it was takeoff loud how can it be takeoff loud with no power? If the 14:1 air:fuel ratio is wrong...

  7. Re:We need this type of thing done in the classroo on Hand-Made Vacuum Tubes · · Score: 1

    No end of projects if you want to go old school. If you get your glass blowing down, you can make a mercury arc rectifier! Its all good right up until the part about the 2kg of mercury needed to "make it happen". Also, the voltages and currents tend to be a bit high. Great to look at! Just don't breath the vapour that leeches out.

  8. great teachers on Professors Slam Java As "Damaging" To Students · · Score: 1

    I had both those professors at NYU. PL/1 with Schonberg and Dewar for compilers. The curriculum back then for a CS major was an inrto language, at the time PL/1, an assembly class (BAL on a 370). Discrete math was a must. Data structures using PL/1, a graph class. OS design and comp arch (others that I forgot I am sure). This was a good challenging major and I am glad they are making the case that the current trend is bad. I agree, its difficult to find good programmers. Bad habits seem to get into folks very early with these hands off the hw languages. That is at least from where I need people (embedded fw). For a web gui perhaps C# and Java are all thats needed these days. To me, I need to understand the hw on up to, if used, the vtable and the objects on top, complete understanding of all the layers. If you dont know your system, how can you grasp the ramnifications of change of any of the pieces (new processor, different compiler, runtime, etc). If you understand all the pieces, your life is ultimately better and easier I feel. I dont think the new CS majors get that training any longer.

    This nefarious landmine I wound not say has 'helped' but it surely has changed lives. Its a plastic mine very little metal content, inexpensive and is the most widely seeded mine in the world. This is the kind of change the world did not and should not ever have needed. Perhaps one day, a high tech soln can dispose of these low tech scourges. There has been a lot of progress but still, its the de-miner with the stick and a face shield that gets them out today.

  15. Re:Whiskey Tango Foxtrot on One Failed NIC Strands 20,000 At LAX · · Score: 1

    Back in the late 80's we had a network of Apollo DN300's. Days of lost time when the ring went down. Once and entire day lost. IT scrambling about in the ceiling tiles trying to TDR the cable, finally, a NIC out in a workstation in a closed office, the employee was on vacation. Whilst on vacation that NIC, like a bad xmas tree bulb took down the whole lan whilst it wouldn't play nice and pass on the token. Total junk and a total waste of time. I used to dream of taking that Apollo from CA to Chemlsford mass and heave it wrapped in lemons at the stairs of Apollo's plant.

  17. stratego, l'attaque, dover patrol, tri-tactics etc on Humans Can Still Out-Bluff Machines · · Score: 3, Insightful

    Games with imperfect information. Very hard to design good AI to play these games, as the story says, tree search is not a win here. A game like stratego also has concepts that go beyond individual piece movement, i.e. you may want to group an few pieces together to make an attack, moving the unit (subject to input from the enemy) forwards. I have yet to see a good stratego game, there is one for $ called "The General". It can be defeated quite easily. I have found a stratego game in the past that could *not* be defeated! But, some sleuthing on my part (via saving the game and restoring it at key points) showed the sw was cheating by moving its pieces around to adjust to the threats(!). I have had an obsession with this style of AI but its such a daunting problem its hard to get a good handle on where to start to chip away at it. I suspect the polaris folks have been doing just this, the AI and methods they develop would be useful for other games I am sure.

  19. Puzzle people on Shredded Secret Police Files Being Reassembled · · Score: 1

    The sacks may contain clues to Puzzle people (according to Anna Funder's book Stasiland). The first files the Stasi shred are the most incriminating. Remember, these fine folks made some of the dissidents back then 'dissapear'. Which files do you think would be into the shredder at the time of the wall coming down? Also realize that they wanted to shred all of it, but they burned out the shredders with the sheer volume. With about 60-70 people per watcher in East Germany, there was a lot of info in a lot of files about a lot of people!

  20. Stasiland by Anna Funder on Shredded Secret Police Files Being Reassembled · · Score: 2, Informative

    I was curious on the Stasi after enjoying the recent(USwise) release of the "Lives of Others" It won an academy award. Anyway, Funders book covers this topic of the sacks of shredded documents. The statistics were rediculous and 100's of years would be needed at the rate they were getting through the sacks. Kindof like the Blechley park people, recruitment seeks special skills, in this case, people who enjoyed board puzzles were hired.

    The book is a good read, this systematic control they had on a society from cradle to grave produced some very odd people and behaviours.

    Check out the film also.

  23. Re:Pump & dump for PHYA on Spam Volume Jumps 35% In November · · Score: 1

    I am also trying to see a way for the mkts to help combat this. The pink sheet market can help here. If spam for a symbol on their market reaches some predefined high water metric, remove the symbol from trading for one week. Another alterative is to allow short selling on the thinly traded issue. The pumper has already taken a position and is most likely the reason why the ask price is so high when the emails start arriving. Shorting would be a clear brake here on exuberance. Once the symbol is out of play, remove the short selling allowance.
