Dynamic Memory Allocation in Embedded Apps?
shootTheMessenger asks: "My company is porting our C++ Windows app to C in an embedded device and the question of whether to use dynamic memory allocation continues to come up. So far I have resisted malloc/free use but it gets tedious having the same argument with the next set of managers to take an interest in the project. Is there a definitive answer on the subject, especially one to counter the 'we have plenty of RAM - 16MB - so why not use dynamic allocation' argument? A quick google search finds that some sites frown on allocations within embedded applications, while others say it is OK in some contexts and yet others hack around it with pseudo-static allocations. How do you feel about this particular subject?" -
Nanotube Non-Volatile Memory Entering Production
hovermike writes "Nantero and LSI Logic are expected to announce that nanotube non-volatile memory will be going into production, at least as far as the NY Times is concerned. Nanotubes have been discussed previously, Nanotube Applications..., and Buckminsterfullerene..., but I'm certainly surprised something like this has moved into production this quickly. Could this be the ultimate 'bubble' memory?" Reader hovermike writes "The press release can be found at the Nantero website. I'm looking forward to only needing one memory card to store all the 5Mbit pictures that I'll take for the rest of my life." -

Ultra High Definition Video
hovermike writes "This story about UHDV (Ultra High Definition Video) comes from the NY Times. Here are a few specs from the article: 'picture size of 7,680 by 4,320 pixels'; 'UHDV's beefed-up refresh rate of 60 frames per second (twice that of conventional video), projected onto a 450-inch diagonal screen with more than 20 channels of audio'; '22.2 sound: 10 speakers at ear level, 9 above and 3 below, with another 2 for low frequency effects'; AND THE KICKER, 'All those sound channels and all those image pixels add up to a lot of data. In test, an 18-minute UHDV video gobbled up 3.5 terabytes of storage (equivalent to about 750 DVD's). The data was transmitted over 16 channels at a total rate of 24 gigabits per second.' Don't think I'll wait to buy regular 'old' HDTV..." -
Optimizations for Source-Based Distributions?
Kenny Mann asks: "I currently run a Linux distribution called Lunar Linux and it is a source based distribution branched from the original Sorcerer GNU Linux. I've done a bit of research on compiler optimizations and such and was wondering what kind of performance is there really to be had for setting these options? I know that the more options the greater chance of unexpected failures, so my next question is what about optimizing your kernel?" Optimization is tricky, and I think the answer to this question is more complex than "yes, optimize" or "no, don't optimize". Rather there might be classes of applications that are safe to optimize and classes of applications that are not. How do those performance hounds out there feel about optimizing the kernel, however? -
Real PDA Wristwatch
Larry Groebe writes "Just before COMDEX, Fossil announced a new PDA in a wristwatch. Based on the Palm OS, this is nothing less than a complete Palm Pilot on your wrist. See here for features and a picture. This is completely UNLIKE Fossil's *first* attempt at a wrist PDA, which was a hopeless view-only gadget. This new model allows regular Graffiti input and appears to run all Palm programs! At $149, I may be the first in line when it comes out next spring." -
2002 ICFP Programming Contest
Phil Bewig writes "The 2002 ICFP Programming Contest begins today. The programming task will be posted at 12:00 noon Pacific Time." Which should be... just about... now. -
Stephenson's Quicksilver Slated For March 7th
Swampper writes: "New Neal Stephenson novel Quicksilver is available for pre-order from Amazon UK. It's due out on March 7th. There is also another Stephenson book on the horizon; Interface. It will arrive May 2nd." Actually, Interface was previously offered through the psuedonym "Stephen Bury" Note the discussion of this book and others on the Cryptonomicon site. -
ICFP 2001 Contest Results
Phil Bewig writes: "Results of the 2001 ICFP Programming Contest (previously mentioned at SlashDot here and here) have been announced. First place is to a program in Haskell, second place is to a program in Dylan, and the judges' prize is to a program in Erlang. The judges also named third place (ocaml) and fourth place (C) entries that were not awarded prizes. ICFP Programming Contest pages for prior years are available: 2000, 1999, and 1998." -
P2P vs. RIAA: RIAA Wins
revscat writes: "Salon has a nice writeup of the persecution and eventual success of the RIAA vs. commercial MP3 entities. And while alternatives exist, they "may eventually succumb to the might of the RIAA, which is already making noises about targeting software developers, ISPs and individual users of the network with lawsuits." Basic gist: for profit MP3 has consolidated into the hands of the recording industry." Plus ca change, plus c'est la meme chose. -
NeXT Lives -- In Apple
mikey writes: "vnunnet.com has an interesting article about Steve Jobs; his love for cubes, a bit of a history behind NeXT, why it failed, also why it was so way ahead of its time, also some Bill Gates stuff. All in all, a great piece, and to give Slashdot readers some insight into what was NeXT, and how now it has basically taken over Apple." -
Delaying Our Visit To The Last Planet
O.F. Fascist writes: "Story over at Space.com about how the first NASA mission to Pluto might get cancelled for a variety of reasons." Sounds like the reasons at play here are good, though -- "reliable transport required" applies to multi-year interplanetary journeys, too. (And what are we looking for on Pluto again?)
