    But just think about it... violet is all the way up there on the upper end of the visible spectrum, the highest energy and yet just barely visible. Plus, the shade of deep, dark violet I like is often polished to a nice iridescent shine... think in the ballpark of #100010

  2. Hearing cars in your blind spot on Radar For Safer Driving · · Score: 1

    My old college beater was a 2-door coupe and had the little "flip-out" rear side windows that I always kept open for ventilation. A nice side effect was that I could always hear traffic in my blind spot.

    I always head check, but it was pretty invaluable having that kind of information always present. Hopefully the engineers can design it so it works passively using your car's audio speakers. Research with fighter pilots has shown that humans can place an audio signal projected somewhere around them to within 5-10 degrees, so it would make sense to use audio for extra proximity alerts. Sure it might be annoying at times, but that would only encourage people not to linger next to other cars, maintain safe following distance, get out of the way of cars tailgating behind them, etc.

  3. Solution from previous slashdot story on A Wireless Network for a 4-Story Apt. Building? · · Score: 1

    There was a story a few months back (can't find it, though, too many other stories on wi-fi) where a guy covered an entire apartment block with two access points - one on each side of the building. Since Wi-fi works line-of-sight, if the tenants could see the access point from their windows, they can use it. I don't know what's across the street from your place, but you could mount it in a tree, power it from a street lamp or from an adjacent building, and use it as a repeater for one or more trunks you have set up to your internet connection inside.

    Of course, this will just give people access... not necessarily good bandwidth since everyone has to share. But I imagine your internet connection is a smaller link than the Wi-fi anyway. This would be a good, cheap start... you wouldn't have to spend much wiring up the building (I don't really see you getting much further with only $7k). You can always spend the rest of the money on upgrades later.

  4. Other non-gaming options on Trying Your Hand at Level Design? · · Score: 1
    Using a gaming engine for interior design projects adds limitations and extra work that you wouldn't have to deal with using other visualization technologies. I wouldn't start a project using a gaming engine unless I already had experience and knew exactly what I could do and could not do using those tools. As an engineer, I find it much easier to work with high-level 3D scene definition tools such as VRML and POVray. These let you play with scene definitions using constructive solid geometry (rather than spending your time fine-tuning polygon meshes) and give you much better control over lighting effects, textures, and environments.

    Here's one of my forays into architectural design using Moray and POVRay. It took about a half day to do working off of graph paper blueprint sketches. Though it's not interactive, the visual quality (architectural composition aside :P ) is much cleaner than anything currently available in a game. VRML is a lot like the POV format, for the most part, so some tools should be able to convert from one to the other, allowing you to use VRML to make your designs interactive. Search around on Freshmeat and the like for tools that might be able to handle both formats...

    Good luck, and have fun!

  5. How long until this data hits Celestia? on You Are Here (On Earth) · · Score: 1

  6. HLA vs. CORBA on Sentient Data Access · · Score: 1
    Well, there's still quite a gap between what HLA was intended to do, and what it actually does. And I suppose I really meant HLA+RTI in order to cover the finer details of simulation time synchronization and such. Here's a good pitch (ppt, unfortunately) comparing HLA vs. CORBA

    The original HLA spec (up to 1.3) as defined by the DoD was kind of nebulous, so much so that the industry groups had to create their own HLA spec that was actually practical/implementable/useful (IEEE 1516). This page provides a good overview on the differences.

  7. Umbrella terms for this type of tech on Sentient Data Access · · Score: 5, Informative
    It's under development under a couple of different names.

    Unfortunately, this kind of thing still starts in the military world. The DoD has been developing requirements for Network Centric Warfare (NCW). Basically turning warfare interfaces into a RTS game like StarCraft, C&C, complete with fog-of-war, semi-autonomous units, comm & data sharing, etc. On the technical side, this is manifesting itself as Command, Control, Communications, Computer, Intelligence, Surveillance and Reconnaissance (C4ISR) architecture. One of the first actual implementations is being worked in in the form of Future Combat Systems (FCS).

    These are complex systems, so the DoD has been maturing development of modeling & simulation interoperability by making contractors adhere to High Level Architecture (HLA) so they can properly analyze these systems before deploying them. HLA basically provides a lot of the same data object registration, distribution, and interfaces that older tech like CORBA does, with extra simulation concepts.

    These technologies are being commercialized under the buzzwords "Nework Centric Operations" (NCO) and "Network Enabled Operations" (NEO). Advocates usually point to well networked operations like Wal-mart, UPS, et al. as poster children for what could be done (automatic restocking, package tracking, load balancing & route optimization, etc.) with enough NEO infrastructure. A lot of the interchange standards (including C4ISR) are getting established through bodies like the OMG. Other than the interchange standards, there's not all that much new tech involved... maybe RFIDs and various other networking tech (grid/mesh networks, strong encryption/authentication, mobile IP, etc.). Most if it just involves looking at technology that already exists and figuring out how to piece it together to actually do something worthwhile.

    Disclaimer: I work for one of the gov't contractors throwing all these buzzwords around.

  8. Step towards direct digital democracy on E-Voting: a Flawed Solution in Search of a Problem · · Score: 1

    Once this technology is proven, this could become a valuable electronic polling tool, not just an e-voting tool. People would be able to vote directly on important issues. Right now, people only elect officials, who look at unofficial news polls to see what the populace thinks, and then tries to act in a way that would get them re-elected. We can do better than this, the technology to accurately determine what every single person in the city/state/nation thinks on important issues just hasn't existed in the past.

    Granted, the whole Diebold thing is grossly botched up, and is a major step backwards in terms of voting transparency.

  10. Systems Engineering & Software Engineering on Cringley on E-voting · · Score: 2, Interesting

    As someone who's studied both, it seems very strange how much they borrow from one another, and yet most practicioners I've met from each field has been thoroughly ignorant of the other.

    From one side, Systems Engineering is quite an old field, mostly championed by the government itself to attach "best practice" management processes to increase the viability of major complex construction projects (since a lot of civil engineering projects were failing at the time). It's basically the simple process of structured decomposition of a complicated problem into a variety of simple ones: problem analysis, requirements, specifications, functional/structural decomposition, building & assembling components, verifying that your system meets the specifications/requirements, and finally validating whether your system actually solves the problem. As systems get more complex, doing all the bookkeeping to keep track of those handfuls of tasks becomes an information management project in and of itself.

    Software engineering came along, and suddenly they were going through major SW projects in 1-2 year cycles, instead of 10-20 year cycles for bridges, dams, buildings, etc. Needless to say, the SW engineers gained experience in full life cycle systems engineering of projects much more quickly than most of the old traditional SE's could build in an entire lifetime. This was both good and bad... As you may well be familiar with, we've raised our SW engineers to enjoy reconstructing things on their own from scratch, and to be somewhat resistant to doing the research on how other related projects / fields have fared in the past. As a result, they've rediscovered many of the SE fundamentals on their own, but at the same time, we're going through the same mistakes that had caused massive project failures in the past to do so.

  11. Re:It's not how much you spend... on India Joins Galileo Consortium · · Score: 2, Informative
    Well, you're sort of nitpicking, as far as where the bulk of our money goes.

    Take a look at these three US Budget plots http://hairball.bumba

    Four items far outweigh all of the others combined: SSA, Healthcare, Treasury (interest on national debt), and Defense. Everything else (including those items you mentioned) add up to diddly. SSA and Healthcare also show no signs of slowing down, and the baby boomers are just starting to retire.

    I'm kind of surprised the Howard Dean campaign has't harped more on this data (which is from the White House budget & management administration itself). If the #1 & #2 things we spend on are SSA and Healthcare (they're listed separately from the rest of the our taxes on our W2's for chrissake), it seems like a doctor would be the kind a person we need to figure out how to trim them surgically without harming the programs as a whole. Then once those things are under control, we could use a good economist and maybe a general to strategically trim the other two big budget items.

    To your credit, the Department of Agriculture is the biggest of the "small fish" budget items. :)

    I have to admit that I'm not enough of a music fan to consider blowing over $100 on something that just plays music. But it would be cool to have it all with me everywhere I go. So far, I haven't seen any integrated small device that does it all, so I've found it cheapest to build everything around a laptop and lug around all the components in the bag:
    • $1400 Dell laptop w/ NVidia 3D card, WiFi, bluetooth, IrDA, USB2.0, Firewire
    • $150 Garmin GPS, plugs into serial port
    • $80 tri-band GSM/GPRS phone w/ bluetooth & IrDA. Right now I just use dialup, but eventually I'll add $20 a month for unlimited GPRS service (~120kbps?) from T-Mobile. I figure I'll get much more use out of this than their WiFi access, since I don't spend all that much time in Starbucks & airports.
    • $150 Quickcam Pro 4000 or whatever for laptops. Haven't bought this yet either, since I already have a normal digital camera ($200), as well as a firewire DV camcorder ($450).
    So all this equipment fits in a bag together and pretty much lets me do whatever I need to do when I go somewhere, just about anywhere:
    • Check email / Slashdot from anywhere around the world with GSM/GPRS/WiFi coverage.
    • Find out where the hell I am, tell me where I'm going, and how to get to a good restaurant when I'm there
    • Take pictures & movies of what I'm doing. Haven't worked out video conferencing yet (no one to video conference to) but it's on the list.
    • oh yeah, play music / movies, both from my entire personal collection, or streaming from the internet
    • Have all of my Personal Organizer info with me, as well as work
    • ...and if I'm not having enough fun where I am, I can play games.
    I'd love it if someone made a small pocket device with all that functionality (PDA, GPS, GSM/GPRS, WiFi, good quality photo & movie camera, music player, & >20GB storage), but I just haven't seen it yet - only in bits and pieces. Until then, I'll likely just continue lugging my backpack around :P
  14. Signal locator would probably be more effective on We're Jammin', Hope You Like Jammin' Too · · Score: 2, Interesting

    Jamming is a solution, but simply being able to locate and reprimand people with cell phones would probably be better in the long run.

    First of all, it's a sociological solution. If people know they can be detected, they would simply concentrate on following the "no cellphone" rule, rather than trying to be discreet or circumventing jamming mechanism (which would lead to a jamming/anti-jamming escalation).

    The detector wouldn't have to be so complex (though it would certainly be tres cool to have a tricorder-like 3D spectrum analyzer). It could be as simple as a wand hooked up to an amplified speaker :P . With a little more work, you could probably tune them to the 2Ghz cell phone frequencies to increase their range and do some triangulation to cover a larger room, and put it on a public display so everyone could see who was violating the no cell phone rule, or forgot to turn them off, etc.

    Same here. It seems like the more junk they add to a phone:

    1) the heavier & bulkier it gets. They were just about to get to the size of a lapel pin that I could wear on my shoulder like a star trek insignia.

    2) the more unstable it gets. There's nothing worse or more embarrassing than losing a call because your phone crashes. This happens even with relatively simple WAP phones, and all the time with the old VisorPhone I had.

    3) the less electronics I would buy. If phones and PDAs were separate and cheaper, I'd upgrade one or the other twice as often.

    Mobile phones should just be interfaces. My current phone was the cheapest I could find with GPRS, IR, and bluetooth. I can use it with my current Visor Pro & laptop with the IR interface, and I'll be able to use it even more with the bluetooth laptop I'm getting next.

I realize some of the requirements are a bit tricky (anonymity vs. auditability), but has no one been able to come up with a strong, secure reference system built from standard OSS components?

    I'd even say to go one step beyond and provide a continuously polling system that would enable a more direct "digital democracy". You wouldn't need to vote at a certain blockpoint. You could just log in your preference on the government server, and it would compute your influence on, say, budgeting for education vs. defense vs. infrastructure, or whether to declare war on someone or not. Having an "official" government polling system for these kinds of issues would do away with a lot of the biased media polls that we resort to for some silly reason today.
