  1. Re:Light source behind the display, glasses? on Computers, Long Hours and Vision Problems? · · Score: 1

    I had the same experience with glasses, and with my optometrist. Thankfully, my parents forced me to do eye exercises when I was young (7-13) and I'm now only somewhat myopic (-3.75 in each eye) instead of nearly legally blind (my father is nearly -10).

  2. Some benefits of this scheme on Pay-As-You-Drive Car Insurance · · Score: 1
    This idea has been floated around for a while, and is expected to have big benefits for certain groups of drivers. The two biggest beneficiaries are likely to be 1) students and 2) the poor.


    There is (unsurprisingly) a high correlation between total miles driven and number of accidents. Right now, your insurance premiums don't account for this at all. The BBC article focuses on the GPS effects of pay-as-you-drive (PAYD), such as charging for types of motorway, time of day, etc., but the really big deal is just knowing the total number of miles driven.


    So how does this help students, or the poor? Well, those two groups typically meet two criteria: high risk, and low financial resources. For these people, there are real benefits to being able to reduce their premiums which they can do by reducing the miles they drive. Right now, if you're a high risk driver, you're SOL - you pay the high premiums and suck it up. With PAYD, you can at least drive less, and still gain the benefits of having a car without breaking the bank.


    (As a side effect, PAYD could help to encourage more sustainable modes of transportation, by making transit/walking/etc. more attractive relative to driving.)


    If you're interested in these issues, check out this article: Pay-as-you-drive pricing for insurance affordability by Todd Litman.


    One interesting note from the article: the reason poor drivers pay more as "higher risk" drivers is geographic. Insurance companies rank poorer neighbourhoods as "high risk", but not because poor drivers are more risky in their behaviour. No, it's because rich neighbourhoods tend to have more underused (second or third) cars, which are very low risk, lowering the risk of the entire neighbourhood.


    And I do agree with the many posts here complaining about the ripoff world of automobile insurance... it's insane how expensive it is, and how cruel those companies are!

  3. Re:UWaterloo's Approach on Ripoff 101: Gouging Students for Textbooks · · Score: 1

    Waterloo's bookstore is definitely the best system I've seen. It's a student-managed business (owned by the federation of students), and it sells books on consignment - you put it in the store and decide the price, they take 10-15% of the sale. It's a fantastic system - I only got stuck with two unsold textbooks in my undergraduate degree, both old editions that weren't very sellable. I recently came to UBC for my M.Sc. and was kind of shocked to learn that most schools don't have a comparable system!

  5. It's called infill, and needs new urban planning on Creating Car Free Cities · · Score: 2, Informative
    Most of the problems with car-centric cities lie in urban planning. Single-use zoning leads to separate residential, commerical and industrial districts. Wide lots limit the uses for the land - i.e., only single family homes, and not higher density housing like duplexes, row houses, or three-story apartment blocks. Suburban sidewalk free zones discourage pedestrians, and winding streets make public transit ineffective.

    You can fix it all by changing the urban planning strategy. I live in Vancouver, and you can see the success of our program. The region is bounded by an Agricultural Land Reserve, and can't grow outwards - so it can only grow by increasing density. This is achieved by "infill" - taking existing low-density lots, and filling in the gaps to increase density. The first target is the surface parking lot, followed by empty malls, brownfield industrial sites, and even upping zoning densities when lots are redeveloped.

    Small steps count. Since amalgamating into a larger megacity, Toronto has forced the suburbs to build sidewalks and bikelanes, and is slowly improving the livability of the outlying regions. Vancouver's downtown is a model of urban high-density redevelopment, as the abandoned portlands and waterfront industrial sites were rebuilt into highly livable condominium towers.

    So don't give up hope - lobby your municipality for better urban planning, and push out the highway engineers!

  7. Re:article credibility on Still More on Global Warming · · Score: 1
    Let's stop for a minute and discuss the scientific review process. Slashdot has just done what so many traditional media outlets do when reporting scientific issues: presented a minority opinion as fact.

    Science advances slowly through peer-reviewed journals. Major scientific papers are reviewed by leaders in the field, and eventually accepted into the top line journals if the research is of sufficiently high quality. If a paper is rejected from a top journal, it is usually submitted to a lesser journal, and so on until it is eventually accepted.

    Science and Nature are among the most prestigious journals for general science publications (but rarely computer science), and any major breakthrough in climate research would likely be published there. This Energy and the Environment journal is one I've never heard of (but I'm not a climate researcher), and doesn't seem to be a commonly cited source. I'd put very little stock in the claims made in the paper, since it hasn't been accepted by the scientific community.

    Print media (like this daily telegraph article) do this sort of thing all the time - claiming that an article in some obscure journal reflects the current state of science, rather than one group's opinion. In Canada, the National Post often presents global warming as a "contentious issue" in the scientific community, treating the handful of dissenting scientists as equal to the majority who believe global warming is occurring. Read between the lines, people.

    A few quick references on the subject (I'm not endorsing anything else on this site, I just found this while searching for "peer review" with Google.

  8. Re:MatLab, Mathematica on Use of Math Languages and Packages in Research? · · Score: 1
    I'm a grad student in computer graphics, touching on computer vision as well.

    I also find Matlab invaluable for prototyping. For matrix operations, it's quite quick and well assembled, and not even much of a "black box", since Matlab/C source for most routines is available. For image processing - well, it's okay, but I can definitely write faster code myself. I often prototype in Matlab, and then translate to C++ for a final, fast edition.

    For computer graphics, Matlab is awkward. When you need complicated data structures for 3D objects (like a winged-edge mesh), Matlab just gets painful.

    In C++, I've tried a few matrix libraries. The Matrix Template Library (MTL) was okay but ugly and not very well maintained. I've heard good things about Blitz, but it wasn't quite right for my problems. Lately, I've preferred Boost's uBLAS library for a clean, STL-style templated C++ matrix library. In the end, your choice of library will depend heavily on your application.

  10. Re:administrative costs? Nice link! on HP Wants Manufacturers To Bear PC Disposal Costs · · Score: 1

    Where are you getting this from? The EU stated that DSD (owner of the green dot program) has too large an advantage due to its large market share - a monopoly type problem, not "abusive" or "wasteful". Sure, the link says that the practice is overly bureaucratic, but that's not the same as wasteful - in fact, it's reducing solid waste.

    And your comment about the "old world" is the wrongheaded. If anything, the USA represents the "old world" way of doing things. The EU is years ahead of North America in terms of environmental programs. (I say this as a Canadian, just as guilty as any American - I'm not trying to start a nationality flamewar here.)

    > What would be good would be binary compatibilty between XMMS and Winamp plugins. Having not looked at Winamp plugin development, I don't know how hard that would be; anyone know how compatible they are/could be?

    *cough*. The Winamp (1.x/2.x) plugin API is absolutely terrible. Let me give you an example. If you want to retrieve the title of the track, what do you do? Well, you get the window handle for Winamp by calling a few Win32 API functions with "WINAMP.EXE" as the argument. Then, you call the Win32 GetWindowTitle function, then you take the resulting string and strip off the "Winamp - " from the front. No, there's no nice exported "GetSongTitle()" function.

    It gets worse. What do you have to do to get id3 information from the playing mp3 file? Well, you get the HWND again using the old approach. Then you send a WM_USER message to get back the index into the playlist of the file being played. Then you send another WM_USER message to get the filename of the playlist. Then you ask Windows politely for Winamp's full path, and use that to build a full path to the playlist. Then you read the playlist file in, and find the ith entry. Then you use id3lib to retrieve the id3 info, after patching id3lib since Winamp generates non-conforming id3 tags.

  21. Dump Katz, get Wood on Assorted Katz Hype · · Score: 1

    This is perhaps one of the most frightening features of the Slashdot comments: probably 60% of the writers haven't read the article. Maybe the new system will help.

    Wood's article is intelligent; his criticism of Slashdot and Katz are entirely valid. I was in the "Katz has nothing to say, but he's innocent enough" camp before this article, but I will filter Katz out from now on. (Well... maybe he'll have a response. That could be amusing.) I have nothing against Katz personally, but I don't like the content of his articles and I think he's a poor advocate for the open source movement. See Wood's article.

    Wood's arguments are solid. I haven't seen Raymond in public, so I can't comment on Wood's analysis of Raymond, but his take on RMS was bang on. While I was turned off by the you-haven't-read-Foucault-yet! attitude, it's entirely valid - philosophizing without knowing philosophy is so much line noise. And dammit, everyone *should* read Foucault. Even if I haven't...

    But would Wood write for Slashdot? Doesn't seem likely. After flaming the site so eloquently, why would he write for it? Besides, if he researches his topics, he couldn't put out anything like Katz's volume, making the counterpoint weak.

    After reading Wood's post, I'm tempted to wait and revise my comments, to think everything through perfectly. But that's not the nature of a discussion board; if every comment were a researched essay it'd be sparse discussion. Sigh. Descending to cliches, I'll just add my two cents to the pot and step out of the fray.

    This brings me back to my original point - commenting without knowledge. It is a discussion board, and anyone can put their opinion out there, even though everyone has varying levels of knowledge of a given topic.

  23. Naïveté is a two way street on Open Letter to the Emulation Community · · Score: 1

    I'm sorry. I respect Panix's comments, I agree with the principles he puts forward, but ultimately I think that this viewpoint is every bit as naïve as his opponents. Emulation has never been about elegance, about sharing. The very roots of the scene lie in warez and demo land; you can't get a ROM or demo to test an emulator without venturing into that territory. Emulator authors do write for the sake of technical beauty, but - like OSS - there's also a large element of prestige. These days, prestige is associated more with usefulness, i.e. the ability to run real games. And so, it is ultimately tied to the ability to get real ROMs. That doesn't mean that the scene can't change. I would like to see a return to the likes of Yoshi, who released large amounts of SNES docs to the community, making new emulators easier and allowing new coders access to the scene. I think that the emu scene still has a lot to learn from the OSS community: if masterworks like NESticle were open source, we might see development on those last few bugs and unimplemented modes, making a perfect emu. (Then again, we might just get another MindRape scenario...) To UltraHLE authors - thanks for keeping the scene alive, if only briefly. To warez kiddies - clue in or screw off! Put up some ROM sites of your own, and *don't* bug the emu authors! Without them, your ROMs are worthless. ROMs are necessary to make the scene worthwhile, since your average N64 owner doesn't have the ROM ripping hardware. It's unfortunate; my idealistic streak would like to keep emus entirely legal. Ah well. As long as there are good boxes to emulate and techie nuts to write the emus, the scene will survive.
