IEEE1394 writes "The Gameboy Advance is due to be released in North America on June 11, 2001. Many reviews of the Japanese units have been done, but I haven't seen one of the North American unit. Futurelooks has snagged a unit and some games recently and has done a thorough review of the unit. Hopefully this will help some of you folks figure out if you should run to your closest Circuit City in the U.S., or Futureshop in Canada to buy it. For a hundred bucks, it's a steal, so you know I'm there! Check it out!" Now if only that screen was touch sensitive;)

tuxpenguin writes: "While playing around with GNutella the other day, I came across this PDF document (HTML Here). It gives figures on the Top 200 businesses in terms of net/gross profits and employees. It also compares this information to the GDP of different countries, campaign contributions, government lobbying etc. I found it to be an interesting read. I also found it interesting, that being a rather contriversial document for big businesses, I came accross it first on a p2p network. Something most major corporations would be thrilled to see disbanded."

AlphaOne asks: "Is there any legal recourse (in California or otherwise) for a spammer sending mail out with MY e-mail address as the forged 'from'? I have received an (only one for now, thankfully) 'undeliverable' message for an e-mail I never sent. Upon closer investigation, it looks like a bounce from a much larger mailing for a porn site. To make matters worse, the message is JavaScript encoded and I had to spend about 30 minutes decoding the message just to figure out who the spammer could potentially be. I'm confident I know at least who was paying for the spamming, but I may not be able to directly track down the spammer him/herself (as is so often the case). Does anyone know of a precident in a case like this? Is it worth litigating if I get bombarded with bounces, hate-mail, removal requests, or anything else?" SPAM is one thing, but cowardly spammers who have to use someone else's address for their crap advertisements is something else. What can one do in this situation?

zardor writes: "According to a spacehab news release, the LEGO company shipped a few bricks up to the station for the cosmonauts to play with. (US astronauts were probably not allowed to play since they can't "engage in commercial activities"). From the news release: "The LEGO Company flew an experiment designed to help students learn about weight and mass. Space Media's STARS Academy global education program developed this experiment, and the Challenger Center for Space Science Education contributed educational materials for it. In this first-ever toy-based experiment on the ISS, cosmonauts attached a LEGO Life on Mars Red Planet Protector toy set to a mass measurement device and determined the oscillation frequency of the toy in the device in order to gauge its mass in space. Cosmonauts videotaped the experiment for educational uses. The LEGO payload also included a promotional banner, which cosmonauts unfurled and photographed in space, and 300 toy ``alien'' figures. Most of the figures will be awarded to winners of the LEGO ``Life on Mars Survival Challenge National Building Contest'' for children aged 5-12. Its a shame they flew the bricks down, otherwise they could have used them to repair that broken CanadaArm 2."

Reefa writes: "The first 3G phone trial has started in Japan. Of the 147000 that applied, 3300 lucky users have been given 3G phones (they have to pay for data access) to test out so that bugs can be fixed before a general release. Example of bugs could be screens freezing up, to which a re-boot (switch off/on) of the phone is the only solution. Kinda reminds me of Windows. Anyway, I am sure that it would be fun to actually test drive one of these FOMA phones. What I would really like to see is real figures of data rates on these phone during peak usage hours." There's also a Reuters story.

bziman asks: "Speaking of fiber, I've been waiting for DSL from Verizon here in Northern Virginia for more than a year now. Their excuse is that even though I'm well within the normal range limitations (I'm only 9,000 ft from the Central Office), I'm not eligble for DSL because half of the line between the CO and my house is fiber optic instead of copper, and they haven't figured out how to run DSL over fiber optic yet. I can get no meaningful answers from Verizon, so I turn to the combined wit and wisdom of Slashdot." Note that it's the hybrid nature of the lines that's the problem, as Verizon already provides DSL for it's all-copper customers. I would think, that customers with all-fiber connections could just be wired directly into the Internet...or is this assumption a fallacy?

basic70 asks: "There seems to be a strong preference for developing new systems all the time, instead of just refactoring and improving existing ones. Why is that? Modifications such as moving to a new operating system, modifying the business logic, adding a web interface, moving to Unicode etc, shouldn't affect more than perhaps 10-20% (to grab figures at random) of a decently built software system. I can think of two reasons myself. The first is that consulting firms make more money developing new systems, and the second that existing systems are so badly layered and modularized that any larger improvements are impossible. The second reason is scary, because that means that the modern way of building things with short lifespans is starting to make its way into the software business as well. I saw a system written in 1995 that couldn't handle the new millenium. Can't we do any better than that? The GNU suite says we can, so why is it so hard with commercial software?"

Anonymous Coward asks: "Like many of Slashdot's readership, I work as an IT guy, and I have quite an interest in techie toys. The result of this is that I wind up lugging around a number of small devices around with me every day. In addition I also carry a number of backup tapes, as I am responsible for my company's offsite backup storage. Unfortunately, I have yet to find the perfect way to cart all of this stuff around. I quickly run out of pockets in the summer, when I don't have a jacket, and if I use my hands, I end up dropping stuff when I go to unlock a door or get out of the car. My poor Rio has its battery held in with a rubber band! I currently use the same case that I use for my laptop, but that's overkill, as I don't take it home every night. I've seen that one company makes a carrying case for a PDA and a cell phone, which also includes a paper planner and resembles a tall CD wallet. This is sort of along the lines of what I'm looking for, but it doesn't hold enough and I have no interest in paper." Yes, we've had questions like this one before, however as the tools one usually carries with them have changed over the course of even the last year, I figure this question deserves to get asked, every so often.

"The ultimate techie carry all would hold all of the following, in a structured way, without being too purse-like:

• PDA
• Cell Phone
• A small quantity of backup tapes, or any small media that you'd wish to transport.
• A portable MP3 player or CD/MP3 player
• Possibly a few CDs, but they already have good cases for that.

as anyone come across anything like this?"

Controlio asks: "With the continuing power crisis and the announcement of major power rate hikes, I figure now is an excellent time to pose this question. Instead of pay these inflated prices for power, I'd like to sink my money into a long-term solution. Cutting myself off from the power grid isn't practical, as I use too much power periodically to be 'solar-only'. But how practical is adding solar for either power redundancy (in case of a blackout) or as supplemental power? Redundancy would be nice, but being supplemental would involve using solar power as my primary power when it's available (and I hear tell that you CAN have negative electric bills if you produce more than you use). Do the costs/advantages for either provide enough incentive to be worth investing in? How would one go about creating a hybrid house? And finally, of course, which is cheaper? Investing in expensive solar paneling, or paying the outrageous charges the power company wants?"

HaiLHaiL writes: "Microsoft's Mundie has a commentary running on ZDNet responding to the responses to his speech. " No real surprises, but it's getting submitted a lot so I figured I'd post it for you. Lots of good points, but I'm sure you can guess the gist of it.

The below review was contributed by reader Lozzer, and deals with a book about one of the most fascinating figures in mathematics history (and cryptograhic history in particular). Nearly half a century after his suicide, Alan Turing is still fascinating and relevant on several levels.

Alan Turing: The Enigma author Andrew Hodges pages 587 publisher Walker & Company rating 8.5 reviewer Lozzer ISBN 0802775802 summary A wide-ranging look at one of the most important mathematical minds, before, during and after his role in breaking WWII codes.

I recently finished reading Andrew Hodge's excellent biography of Alan Turing. The second edition was printed in 1992. It included updates based on material declassified by the British Government (Amazon has a 2000 edition, I'm not sure if this is a rewrite or a reprint). Weighing in at nearly 600 pages the book is not for the faint hearted Geek.

For our younger Script Kiddies I'll give a brief overview of Turing's life and what he has to do with computing. He was born in London in 1912 and christened Alan Mathison Turing. After a public school up-bringing he studied maths at King's College, Cambridge from 1931. In 1935 he solved part of one of the great mathematical problems of the time: Hilbert's Second Problem. Godel had solved the first two parts. Turing solved the last part about deciding which mathematical statements were true. His construction for solving this problem was the Turing Machine. This model forms the basis for all modern day computers.

Between this breakthrough and the war, Turing spent a couple of years at Princeton, where he studied under Alonzo Church and John von Neumann, both of whom where pioneers in the computing field.

With the onset of war in 1939 Turing found himself employed as a code breaker at Bletchley Park (which is only a couple of miles from where I live). This is where Turing's theoretical knowledge began to take physical shape. By the end of the war the Colossus had been built. This is sometimes touted as the first computer, though I'll leave that to people with flame retartant underpants. Suffice it to say this "computer" could only be programmed by reconfiguring the hardware.

After the war Turing gravitated to the University of Manchester where he took a role in developing the first prototype computer that was "software" programmable. After that he became a programmer, using the computer to help with mathematical theories. He was convicted of Gross Indecency (Turing was a homosexual) in 1952, and had to suffer a year of oestrogen injections to "cure" him. He committed suicide in 1954.

After that potted history, back to the book. It draws on a lot of sources and manages to bring them together in a very coherent whole. As well as providing a British view of the history of computing it also gives an interesting perspective on the changes in society over the years. The book also conveys Turing's breadth of knowledge and vision well - while most computer users were thinking of mathematical problems he was into AI, chess and other abstract symbolism. He figured out the need for subroutines, was the first to use binary (he noted that routines could change the external notation for human consumption, but continued to use 32 bit numbers entered in reverse order himself). He considered hardware acceleration. The author does well in explaining the scientific portions of the book in a clear and correct fashion. From a Geek perspective the text is possibly a bit dense, with some less interesting chunks (the homosexual aspects of Turing's life, for example, have less impact now than when the book was first published).

I recommend the book if you are interested in some of the wider aspects of Turing's life. For me, being British, having a Cambridge maths degree (ooh shameless), and living near Bletchley brings a lot more of the book to life that it may for most. If you are only interested in Turing's impact on the world of computers there are good online resources for this. Maybe, however, you won't find out why Christopher Strachey was the world's first Hacker."

AntiNorm asks: "I recently installed Mandrake 8.0, and after taking much time to get it working, I found that the free version of WordPerfect 8 would not install. The same thing happened under Redhat 7.0, although it installed and worked fine under RH 6.2. It appears that the binaries (wpinstc and wpinstg) that are called by the installation scripts are unable to find a particular file or library that they need, but I haven't been able to figure out anything beyond that. Has anyone else had this problem? If so, is there a way to get around it?" Update: 05/10 04:27 PM by C : Another similar question hit the bin, today, except this one is about Wordperfect 2000. Are the same problems from WP8 inherited in the latest version? Read more, below.

eadint asks: "I've been using Linux since 1996 and about a year and a half ago when Corel Office 2000 for :inux was released I finally got rid of my Windows partition and started using Linux as my sole operating system. Recently I upgraded to Red Hat 7.1 and I haven't been able to install it on my computer. I'm hoping for some advice on this and also hoping that I don't have to downgrade my OS. I can definitely notice a difference in speed with 7.1"

Isldeur writes: "Dennis Powell has a very interesting article on GNOME, Eazel, and the control thereof. However, while it is very thought provoking, it might inspire some heat. Still, I think these things are manifestly important to the ideal of Free Software to figure out!" A very well written article that says a lot of truth. I tend to think that some points are over beaten (lack of binaries for example. So what? Anyone can compile and distribute their own). Especially interesting is the point about Eazel and Paypal, and the comparison to OS/2. The difference, of course, is that this is Free Software in the speech sense, so it's a little more important than OS/2 IMHO. But there's some spicy words in here, and it's worth thought for those with objective minds.

Patrick Darden asks: "Alacritech has a series of high performance FastEther NICs that offload the IP stack onto ASICs. They call it Session Layer Interface Card technology (SLIC) and claim that it increases TCP performance tremendously. PC Magazine has reviewed this card twice (the latest here) and shows 16-400% speed boosts over other NICs. They have a single port, dual port, and quad port. These are for NT only right now, but Linux drivers are in the pipe. Intel has a NIC geared towards servers that they claim decreases CPU usage tremendously. But only for NT. 3Com has a similar NIC, also only for NT (afaik). What is the best FastEther NIC for Linux? Are there any performance roundups? Any studies based on real criteria? Any real performance figures?" What about FastEther drivers for the other Unicies out there? There was a similar Ask Slashdot about this about two months ago. Is this a substantially different technology, or just more of the same under a different name?

"I'm also curious about Gigether and ATM? Until now, I have always chosen NICs for Linux by compatibility and driver maturity. At this point, it seems reasonable to grab the better NICs and have a shootout, if someone else hasn't already. If anyone is interested in helping, or knows of a similar study, please send me an email."

William asks: "I'm currently writing PHP and MySQL code that runs a website that is receiving a modest amount of hits per day. Currently we are able to reasonably pay the montly costs of running this website without a problem, but we are growing larger every month and I could imagine that in the not so far future we will need to start finding ways to finance the cost of running the site. One thing that conserns me is that more and more websites that are being run by average people are on thier way to being down now because they can not afford to pay for the amount of resources being pushed through every month. Up until now banner ads have help displace the cost of running a site, but from what I've been seeing, that is no longer true. I remeber when Slashdot was just Chips&Dips, and figure this would be the place to go when asking how to scale up a website in an affordable manner."

Teach writes: "If my calculations are correct, on Thursday, April 19, 2001, at 04:25:21 UTC (00:25:21 EDT and late Wednesday at 21:25:21 PDT), the UNIX clock will read 987654321, which is pretty cool. This will be the first of two such "significant" events in 2001, the second being 01:46:39 UTC on 2001-09-09, when the clock will read 999999999 (and then of course "roll over" to 1000000000 one second later). Use the Time Zone Converter to help you figure out when this will occur in your area, or read up on other critical dates (such as when the 32-bit signed UNIX clock overflows in 2038)."

A Not-so Anonymous Coward asks: "This is day three of trying to find a .PRC file or something that would enable me to dial out from my visor using a cable connection to my Nokia 6160m phone. The Nokia 6160's don't have IR capabilites so getting the SERIALIRPN1.PRC and the SERIRCOMMLIB.PRC files won't help. these files would be needed if I were trying to use IR, but as you can see, don't need them. The Visor only has a Palm OS of 3.1 and can only update it with a patch of which would make like easier if there was such a thing. So, what can I do while on the road when I want to download a map or check email? I can connect through a conventional phone line, since I have the Circom globalaccess modem for the Visor, but it won't dial through the mobile connection cable since it keeps looking for the conventional phone line! Am I just out of luck here? Does anyone feel especially creative, to try and figure this one out?"

John Squeaker writes: "Last week while the rest of the world was worrying about corporations warning, and dot coms failing, 300 smalltalkers got together in Chicago to plan for the future. Given the fact corporations like Dell have canceled their user conference this year we were very pleased with the attendence figures. The conference hosted a key note by Alan Kay, a *must* read, and the mood and general feeling of the show was captured in this excellent trip report. More information on the conference plus links to the papers/tutorials presented there can be found at the conference site. Do you want to know where OO languages like Java, Ruby, Squeak, and SmallScript come from? Then come visit us for the real story, and see what you can expect to hear in the next five years." The whole thing is interesting, but I particularly liked Tuesday. Smalltalkers seem to have a secret from everyone else sometimes ...

Over the past few months, several questions regarding wiring home LANs have been submitted to the Ask Slashdot bin. These questions cover just about every aspect a person might be faced with when trying to wire a home, so I thought it was best to just collect them all in one go. I figure there are a number of people out there who have done this (I just got finished wiring mine, for that matter), and that there are many more out there who have been searching around for assistance. So if you've ever been interested in building a home LAN from the ground up, or if you have already done so and would like to comment on your experiences, please pull up a chair and share what's on your mind.

Wired, or Wireless? RickMuller asks: "I have a cable modem feeding into an ethernet hub in my house, of off which I string anywhere from 2-5 different computers. Currently these are all clustered near the cable modem itself. I would like to be able to spread the computers through my house, and particularly to be able to bring my laptop to other parts of the house and still be able to work online. I'm considering either hiring an electrician to wire the walls, or finding some wireless format. Wireless is definitely cooler, but I'm a little bit scared off by the 'tower of babel' of different formats. Plus the expense is a consideration. Can anyone else offer an opinion on wireless vs. wired at home, and if wireless, which wireless format?"

Sticking with the open solution is always the best, so I would go with an IEEE 802.11 based network for the wireless segment. Are there any wireless cards that do not grok 802.11? If so, then I'd stay well away from these unless the cost savings are really huge, which I doubt.

Building the Home of the 21st Century! Cactii submits: "My wife and I are thinkng about buying a home soon. We both have our own ideas about what the place is going to be like and the immediate improvements we will make to the existing structure of the house. My ideas involve electronic interfaces to different areas of the house. Wiring the house for a network and using the computer for almost everything that it can be used for.

First off - I'm going to wire the living room or family room into a total entertainment center. It'll have the usual stereo, TV, DVD, VCR, etc... However there'll also be a computer connected to a proxy server that allows instant internet access. The computer will allow us to surf the net and download MP3's to be played right off the computer hard drive through the stereo and other things as well.

I've been looking around for other 'Wired Home' solutions and all I've found were some programs and electronic gizmos that offer only a piece of the solution. X10.com is about as close to a solution as anything but I don't want all these little boxes hanging off of the wall plugs.

Has anybody found anything more integral? More of a total solution?"

Wiring A Home With an Eye on the Future? Oroborus asks: "My parents are building a new house from ground up, and want to try to be as 'forward compatible' as possible. They've asked for my help in incorporating as much technology as possible, and in preparing it for any future technology that we can forsee. The problem is that though they're excited by technology, they're not all that conversant with it, and anything they include will have to be extremely user friendly. My initial thought is to wire the house with shielded ethernet cable with all the drops in the basement, to be wired to a hub/router later. But they've got high hopes for a 'smart home', how else can they prepare for the future?"

A tough job, but maybe with a bit of thought, such things can be prepared for. How would you wire a home with an eye on making it so that future capabilities can be added in without painful construction bills?

Wiring Hostile Home Environments? Old Man Kensey issues the following query: "I've been annoying my roommate by populating every possible room in our apartment with a terminal of some kind (X over the Ethernet, null-modem PPP, or serial). There are two rooms I have not yet found suitable equipment for, though -- the kitchen and the bathroom. The bathroom has the obvious hazards, besides being pretty small, but the kitchen is even more hostile an environment. Besides water, you have various kinds of food and food-related goo, microwave radiation, heat, high humidity, and general cramped space.

Has anybody out there found cheap, readily-available equipment (serial terminals, etc.) that will withstand the worst hazards of a typical American home? How about cheap modifications like enclosures that fit in small spaces and might protect, say, a PowerBook-Duo-size laptop? I'm willing to deal with having to power up and down, but I'd like to have something that doesn't compromise the actual operation of the equipment (enclosures that block cooling fan vents, for example)."

You Can Wire in More Than a LAN, You Know... Cosimo Leipold asks: "I've recently purchased a house that is still under construction. The developer asked me what I wanted wired. Has anyone expiremented with what you can wire in a home sucesfully? The developer has no 'computer experience' of course, so beyond RJ-45 he didn't know what was feasible. He tells me that the cost of wiring is pretty minimal since the house has little more than the frame up at this point. I'm looking to the slashdot community for cool ideas as to what I can wire. (RJ-45, sound, s-video, intercom, etc). I'm thinking this might be a great chance to get X10 in. Ideas?"

It seems that a lot of people have discovered X10 for home automation, but is that the only game in town? Sure, it might be the most affordable, but for those people with larger pocket books, are there other alternatives that might offer more features for a larger pricetag?

...and Along the Same Vein, Why Not Wire for Sound? Last, but most certainly not least, wiremonkey puts this question on the table: "I hear a lot of talk about wiring homes, but very few people are thinking about anything except network/telephone wiring. I'm interested in how fellow geeks have wired their houses for audio. Right now, I have a system built around a Samson 24 channel mixer and two amplifiers. My audio sources include computers, CD players, ham radios, a tape deck, DVD, VCR, and TV. The current system lets me listen to different things in two 'zones' - the computer room vs. the rest of the house (I like my computers to beep in the computer room, but not the bedroom - yet I like my CD player to play music in both rooms). Note that I always have one compter's audio playing throughout the house, as it announces my telephone calls.

I'm looking at ways of distributing the control of the audio 'mix' to two locations (right now, you have to be at the main mixer to adjust something). I would locate the video equipment and an additional CD player in the living room, while I would locate the computer equipment and auxilary audio gear (tape deck, ham radio, another CD player) in the computer room. I'd like to be able to hear any audio source from any room. I'm a serious listener, and I hate 60hz hum (the current unbalanced audio lines I use cause nothing but problems with hum)! In addition, I live in a high RF environment, with HF, VHF, and UHF transmitters and 100 watts of power per band. I get sick of hearing my automated packet station while listening to Bach! At the same time, I would prefer not to run 20+ balanced lines between the two locations. What have you done in your house? What were the 'professional touches' that you added? What did you wish you did differently?

(Yes, I know there are turn-key systems that do this - however, I don't feel like spending $2000+ for a system which won't let me listen to my computer and CDs at the same time!)"

Pedrito writes "CNN is running a story here about a new theory that competes with the Big Bang. I figured it would already be up here. The theory goes that the universe "existed" before as a vacuous space, devoid of matter or energy. Two universes collided and the collision brought matter and energy to the void. The theory explains some things that the Big Bang doesn't. It's also partially based in String theory, of which I'm a big believer."
