I read my email using a text mode browser. No matter how childish it may be, I can't read html-only emails unless I sit down and manually read through the source. Effectively, MSN has decided to shut me out of the loop.
Whenver someone sends me html-only email, I inform them that I can't read their email. If they refuse to send text, what can I do? They're the ones sending non-standard email formats.
I would recommend a look at Soft Typing (often in the context of scheme) and also Dylan's type system.
If you give up the optional typing, foo looks very much like a polymorphic function. Haskell's type system would type it as foo:: Quotable a => a -> Symbol. Perhaps someone with more up-to-date understanding of types can compare F-Bounded Quantification to Haskell's Type Classes.
I checked their site and didn't see they saying anything about their displays not working with Matrox cards.
You're absolutely right. They had a little table, and I remembered that two out of three adapter kinds worked fine, while the third didn't with the HD. Turns out it wasn't Matrox, like I reconstructed in my memory, but the ATI rage and PCI boards that were pariah.
or you could design a language like algol-xx with call-by-name. There you really COULD write that sort of code. The order of evaluation got kinda hairy tho, if I recall correctly.

I've scrimped up engouh money for one of the now cheapish 23" HD Cinema displays (1920x1200 of rock-steady pixel lovin') from Apple. Unfortunately, I'll have to upgrade my ATI AIW Radeon because it puts out a max of 1280x1024 to DVI. I'll need a DVI->ADC converter to drive the monitor, which runs about $100. I now have VERY cach little left for the video card.
Can anyone suggest a video card with good Linux support, able to put out DVI at the above res, and able to scale DVD video to that size? I don't ever use 3d, so performance is less of an issue. Price and linux support are tho. I notice apple's website suggests that the HD display hates matrox, loves ATI or nvidia. Any idea why?
Best of all woudl be if you actually have such a setup running, and can confirm it works
Never used a TV satelite dish have ya sonny? You have to aim the dish fairly accurately at the satelite, which kinda requires that it be where it should. Since you never get perfect geosynch (IANAOrbitalEngineer, but stands to reason), you need to use little spurts of attitude jets to keep in place. You'll also need these to despin the gyros that maintain attitude from time to time.
The punchline is that these XM radio receivers, like GPS, don't require a dish to be pointed at the satelite, so it's free to stray further from it's assigned station. This allows you to use less fuel in staying in place.
But then, you're probably a troll, so I just wasted my breath.
I like to preview albums before adding them to my permanent collection. The ability to mark an album as crap (or perhaps more usefully as techo, downbeat, ethnic) would be great on the move. I don't have an iPod, so I don't know whether such mark-up is possible, but being able to delete albums would be the minimally useful thing.
JUnit is unit testing for Java, right? How does the JVM dumping core become the application's fault? How does network IO have ANYTHING to do with unit testing (unless you're testing a network app that is)?
I mistyped -- made sense to me at the time, but not what I meant upon rereading it. I wrote: > Say you need to map 2**30 names. Give each name 256 bytes to list the hosts using that ip
I meant to write: Say you need to map 2**30 addresses. Give each address 256 bytes to list the host names using that ip
ok. So 256 is an arbitrary limit. However, assuming that most addresses wont use all 256 bytes, you should be able to borrow some bytes from lines that aren't using 'em. The whole thing was meant as a ballpark estimate. I made up the assumption that only 1 IP in 4 is named, too. Give it a few years, and I won't need to make these assumptions either.
ya know, that's not impossible these days. What with the private subnets you can't get to, and coorporations buying up whole class IP blocks, you're not going to need to map every single IP to a set of names.
Say you need to map 2**30 names. Give each name 256 bytes to list the hosts using that ip. You've just used 256GB. Alot, yes, but I'm willing to bet at least one person reading this has that much storage dedicated to MP3s.

Re:JVM actually has more languages than .NET (CLR)
on
The Future of Java?
·
· Score: 1
It's more of a question of _how well_ a VM runs a language. The designers knew better, but failed to propagate certain properties to the final design ( for reasons either political or practical). These issues make the JVM very difficult to target from functional languages.
Which is a shame, because even if you don't like them as a whole, functional languages have some REALLY nice concepts. In particular, the JVM makes it very difficult to model continuations and tail calls.
When you look at that list of JVM languages, group them into language categories. I suspect you'll see that the JVM has relatively little support from non-OOish languages. Which is not to say it can't be done (witness ML for the JVM), but it is REALLY hard to do well.
For all their Evil-Emipire posturing, M$ asked researchers about what sort of properties the.NET VM needed..NET is rumored to be a much nicer target than the JVM.
I think your memory is playing tricks with you, or you with us.
The parent is right. Regardless of whether you record analog or digital, you'd still need to record the same ammount of signal. Even giving analog every benefit of the doubt, and assuming he has an ideal machine, you'll need to scale tape speed to match the maximum frequency you wish to record.
A random google page gives 22KHz at 3.75 inch/s at 63dB for an old reel-to-reel tape player circa 1973. I'm assuming that S/N Ratio is good enough for TV. Now, 1.2 GHz is 545454 times higher than 22 KHz. That puts the tape useage at 17045 feet per second.
Even given advances in tape technology that perhaps halve the speed necessary, and even if you run several machines at once, that's just a boatload of tape.
Nylund was more enjoyable than well written. Ie, the story is strong enough to overcome the sometimes stilted writing. If you buy those books, buy both (they are really one book published in two volumes), and force yourself to finish the first one (the second is significantly better written than the first -- with any luck his next books will be even better written with the same strong plots). But well worth the read, all in all.
I don't know Watts. What sort of writing is it?
On a completely different note, If you like the Asimov style SF, you may want to pick up some Charles Sheffield. Be somewhat careful about what you buy as the same book (or at least same plot) has been published under two different titles (forget which tho. Sorry). In particular, I recommend "The compleat McAndrew" for well done Engineer-as-hero shorts. His "The Web between Worlds" is remarkable for being accused of plagarising Clarke's space elevators (Sheffield's book takes the concept in a very different direction, and since Clarke had no problem with it, neither do I). I suspect that Baxter is a fan of this book, as "Manifold:Space"'s super-smart-squid and protagonist Malenfant have clear counterparts in Web.
Lastly, (and then I promise to stop), on the cyberpunk level, I'd recommend Alex Effinger's (RIP) Marid series. Arab cyberpunk kicks ass! Also (if only because I can't seem to find these books anywhere) Walter Jon Williams' "Hardwired" (strong recommend) was probably the first cyberpunk I'd ever read. "Days of Atonement" (recommend) is good Twilight-Zone-meets-detective , while "Aristoi" is almost Piers Anthonyesq (that's not a Good Thing, IMHO). A brief web search indicates that he's now writing Star Wars novellas, which I am having a hard time reconciling with the style of what I've read, but there you go.
Anyways. Jeff Noon is one of those fantastic authors who resists classification into either fiction, SF, or just plain enjoyable. Highly recommended.
For a more litterate approach, I'd recommend some Borges. John Brunner can often be found in bargain bins. Get "Stand on Zanzibar" and "Squares of the City". Both good. I've read "The Infinitive of Go", but couldn't tell you what it was about. Forgettable.
I'd like to unrecommend Baxter, whose superb Xeelee series lured me into buying the deplorable Manifold series. Titan also blew. These books are bad enough to have me contemplating demanding a refund. Yes, I do have a bone to pick with him.
Similarly Greg Bear started very strongly with two or three Eon books, the great children-revenging-earth series, and some really good near-future detective stories, but recently has severely dissapointed with both "Darwin's Radio" and "Vitals". He has yet to earn a blanket disrecommendation: two duds out of 10 odd books ain't bad, but it is worrying that both duds were in a row. This suggests that like Baxter he may be searching for a new twist/style , and is not finding one.
Perennial favorites (by virtue of liking all their books) are Ken Mcleod and Iain Banks. Both write fairly unchallenging, but very fun, space opera. Watch out for Mr. Bank's non-SF output, which is not up to the level of his SF (IMHO).

I'm calling bullshit on this one.
while it would be easy to go on the web to find out, let's apply some math to the problem.
10Mb/s = 600 Mb/m = 75 MB/m
So if you want to encode an 100 minute movie on one disk (fair assumption) that disk would need to hold 7.5 GB.
I personally don't recall the storage capacity of a DVD, but I thought it was lower than that, on the order of 5 GB.
