  1. Wiki link - Option values on Employee Stock Options Must be Treated as Expenses · · Score: 2, Informative

    Mod parent up, Black-Scholes is the most common way to value options. It uses expected volatility in the stock price together with the time horizion until the option expires to calculate a value. A lot of trading sites (etrade, anyway) will calculate option values for you using this model.

  2. Re:[Almost] Misses the point about SLR cameras on Guide to your Perfect Digital Camera · · Score: 1

    I grant you both of those points, current preview screens can't provide enough the quality you get looking out the glass. And there is room for a preference for holding the camera to your face, although I suspect a good amount of that is what you're used to.

    I still think an SLR digital is akin to hanging lanterns on your new model T. The primary reason for a mechanical mirror is gone when you can look right "through" the ccd.

  3. Misses the point about SLR cameras on Guide to your Perfect Digital Camera · · Score: 1

    An SLR camera (Single Lens - Reflex) was an innovation because you could actually see through the lens that the picture was going to be taken through. Other cameras had a secondary viewfinder lens that could only approximate the final picture. In an SLR camera, you see through the lens via a mirror that flips out of the way when you take a shot.

    With a digital camera and preview screen, you ARE seeing what the camera sees, through the lens, without bothering to use a bulky mechanical mirror. The other points the author makes about controlling the aperature and shutter speed seperately, in order to control the depth of field, have NOTHING TO DO with the camera being an SLR. Those features could be added to any camera with the right lens. They have traditionally been available on SLR cameras because they are high end. No photographer interested in controlling the aperature wants the parallax you get with a two-lens point and shoot 35MM.

    SLR makes no sense on digital cameras with a preview screen.

    I could see IBM pitching OSX desktops to sit beside their linux servers. OSX is the premier unix desktop. Imagine a partnership where Apple lets IBM license OSX installed on cheaper hardware. Although that seems unlikely given apple's past, but you can see the appeal to IBM. And I'm sure there are some CIOs who would migrate to osx via IBM, you hear stories of successful linux rollouts.

    It makes just enough sense to imagine it, I just don't see them getting over the hump.

  12. Something like an RFC for EULAs on Robolawyer to Handle Clickwraps? · · Score: 1

    If you think about licenses, people will say this license is "GPL Compatible", or that one isn't.

    Wouldn't it be interesting to encapsulate the most common atoms of a software license, so a company could select from a few well-understood license components. You would add the concept that if you're SEL (standard eula license) 1.0 compatible, than you can't add any sneaky gotchas to your license. Then you could add a section of eula codes to your license that a client could parse.

    Yeah, I just checked, it's there now. I wanted to do this in (I believe) office 2k and it was not available. I'm surprised they added it frankly, to me office document non-portability is MS's biggest market advantage and not being able to change the default save-as type guarenteed it.

    Of course, you can't make businesses care about portability. If all of your internal documents were portable though, imagine the bargining power that would give you at license time. That's how you sell it to your PHB.

  15. Thin end of the wedge on Star/OpenOffice XML Format To Become ISO Standard? · · Score: 2, Insightful

    It doesn't have to "lure people away from Microsoft Office". All we need to break the Office monopoly is a setting in Office to change the default save-as file type. Ever wonder why there isn't one?

    Sure you can save as RTF, but only if you change the file type every time. That makes a corporate policy of portable file types impossible to enforce. MSFT can say they support X number of formats but until you can specify a non-MS default format you will never get the majority of users to save in cross-platform files. The network effect makes sure that once a mojority of users are using office, then everyone needs to use office (and the latest version of office at that). You can make a suite that's MS compatible, but it will always be at best 99% compatible and likely a version behind.

    If you could specify a portable format as the default corporate wide you'd be in a position, after the new format had some time to soak in, to begin looking at alternatives.

  16. Re:Business model? on Human-Powered Spam Filtering · · Score: 1


    If all 2400 people got 100 emails a day you'd be looking at 2.7 emails a second. But how many are unique emails?

    One aspect of spam is that you're looking for a million copies of the same email after headers. if you only look at unique emails (by hash?) for ALL of your customers you're probably in better shape.

    Even if every spam were tweaked slightly by the sender, there is most likely a signature that you could pick out to identify a specific spam and discard all 12 million copies at once. this kind of manual filtering would work great across many mailboxes.

  18. 3.5" RAM drive with embedded 2.5" HD on Ultra Fast Disk Drives With No Moving Parts · · Score: 1

    Seems like you could dodge the whole flash lifespan issue by making a 3.5" drive with an embedded laptop harddrive and sdram. You would lose half of your target market by adding the moving parts but it would still be a pretty hot cache drive for a lot of apps.

    Take a 4 gig laptop harddrive and add 4 gig of RAM cache to it with write-behind. You'd be screwed if you unplugged it right after a write, but that's always generally been the case. You could afford journaling on the HD to mitigate the risk of a dropped write. On startup it dumps the harddrive to memory, internal i/o is fast.
