New Science Books To Be Available Free Online 95

fm6 writes "Bloomsbury Publishing, best known for the Harry Potter books, has announced a new series of science books that will be available for free online. Bloomsbury thinks they can make enough money off of hard-copy sales to turn a 'small profit.' The online version will be covered by a Creative Commons license which allows free non-commercial use. They've already had some success with the one book they've published this way, Larry Lessig's 'Remix: Making Art and Commerce thrive in the Hybrid Economy.' The series, 'Science, Ethics and Innovation,' will be edited by Sir John Sulston, Nobel prize winner and one of the architects of the Human Genome Project."

Alienware Refusing Customers As Thieves 665

ChrisPaget writes "Thinking about buying Alienware (now owned by Dell)? Think again. After buying an almost-new Alienware laptop on eBay, I've spent the last week trying to get hold of a Smart Bay caddy to connect a second hard drive (about $150 for $5 of bent metal). Four different Alienware teams have refused to even give me a price on this accessory, instead accusing me of stealing the machine since I didn't buy it directly from their eBay store. They want me to persuade the eBay seller I did buy it from to add me as an authorized user of his Alienware account — they have no concept of 'ownership transfer' and instead assume that if you're not in their system, you must be a thief."

My take is slightly different: I believe they were afraid to fail. Given what little we do know about the endless delays -- that they switched the basic engine from Quake II to Unreal to Unreal Tournament to Quake III to one being built solely in-house, and had to restart level work every time, I believe that this was driven by the fear that the game would be a failure. Duke 3D was a smash it. It put them on the map. And they promised to themselves and their fans that DNF would be even better. So, they couldn't stand the thought of it possibly being a flop; it had to be a #1 bestseller, and every game reviewer had to be able to rant and rave at how much more amazing it was over D3D or any other FPS for that matter. And every year that passed, and every time they got more and more ridiculed at its "vaporware" status, it hardened their resolve that the game must not be a failure, or even mediocre, under any circumstance whatsoever. And that mentality paralyzed them, and caused them to essentially re-write and re-write the game, until the weight of it all finally caused them to collapse

Comment Re:Complaints about X (Score 1) 487

You're totally wrong. There's a huge benefit to pushing mouse tracking and drawing to the server, instead of spreading it out over the network or between processes running in different address spaces.

You may be confused, because the terms "client" and "server" have switched place between the NeWS or X11 window server and client application, and the web server and web browser client. The web server is like a NeWS or X11 client application, and the web browser is like the NeWS or X11 server.

Most people run X clients locally, and don't take advantage of its network ability. The direct rendering and hardware access stuff certainly doesn't operate over the network.

The problem still exists, even more so than before, but the solution has moved up a layer on the stack to the web browser instead of the window server, because of X's failure to provide an extensible network efficient protocol. Instead of sending pure PostScript to the window server, you send an amalgamate of JavaScript, JSON, XML, HTML and CSS to the web browser.

The web browser IS a graphics server. If there is no value sending executable code to the graphics server, then why is AJAX so popular and powerful?

Compared to the purity and simplicity of NeWS's use of PostScript for programming, rendering an data represention, today's piebald AJAX solution is a shotgun marriage of inelegant competing technologies that weren't designed to work together.

Case in point: Why is JSON so popular, when we have XML? Answer: Because XML HTTP Request won't let you download XML from sites other than the one you downloaded the web page from, even though XML is not executable, although you CAN download executable JavaScript and JSON from different sites. So why the pointless restriction? Purely a historical accident. The executable content cat's already out of the bag, and JSON's just working around stupid design flaws in Microsoft's XML HTTP Request.

Comment Re:Multi-player SimCity -- open source Micropolis (Score 1) 329

Some more notes on the multi player SimCity user interface from a talk I gave about pie menus at Xerox PARC in 1998:

Natural Selection: The Evolution of Pie Menus

Multi player voting on important issues and expensive zones.

Voting dialogs require unanimous vote of all players to do important things like change tax rate, build expensive buildings, quit the game (although anyone can quit themselves, everyone must agree to shut the whole game down). Any person can dissent by pressing cancel button. OK button requires each person to press it. The beveled edges are extra thick: as many times thicker than usual, as there are yes votes required. As each person votes "yes" it lowers one normal thickness down deeper, until the last vote fully depresses it.

Bouncing building gets closer to ground as more people vote for them., Finally falls "down to earth" as the last person votes for it. Any person can cancel a vote since they require unanimous consent. Bouncing buildings also display a parallel multi player voting dialog, and the bouncing building is a shortcut to the dialog. To vote yes, you just place the same building in the same place. To change the proposed location, you place the same building somewhere else, and it resets to only having your vote.

TomTom's HD Traffic system combines the standard (and spurious) traffic reports, roadway sensors, and other information with real-time data collected from cell phone towers, and it's continuously monitored 24/7 in the HD Traffic Control Center to filter out misinformation and prevent abuse.

So not only would there be no point to hacking TomTom HD Traffic, but it would be very difficult to hack without resorting to all kinds of felonious, easily detected activities.

Comment Good reason to have a separate PND and cell phone. (Score 1) 119

The problem with using your cell phone as a personal navigation device, is that when the batteries run out quickly, you can't call for help. You're lost AND disconnected at the same time.

TomTom's HD Traffic and IQ Routes (which I described in a message above) works well because it runs on a separate device that has its own dedicated cell phone and SIM card, which plugs into your car charger for power. Plus it has a big touch screen, a loud speaker, and a dashboard mount, which makes it much more safe to use hands free while driving. So you don't have to stop talking on your phone, use your phone's batteries, or use your phone's data plan, to download real time traffic updates.

Comment Re:TomTom did it! [HD Traffic, IQ Routes] (Score 1) 119

TomTom's "HD Traffic" gets information on traffic speed from all drivers who have a Vodaphone cell phone in their car.

It does not require each of those drivers to have TomTom devices. It does not require the cell phones to have GPS trackers. It does not require the cell phones to use air time or have unlimited data plans, or even have the ability to connect to the internet.

[Disclosure: I work for TomTom. Whenever I go down to the lunch room, I walk by the HD traffic control center where they collect and distribute all the traffic information -- it has a glass wall like a fish tank with a big screen in front displaying the live traffic feeds.]

The "chicken and egg" and "critical mass" problems are solved by combining traffic data from several different source, and getting a lot more data points than we would get if we only collected data from drivers who have a TomTom that's always connected to the internet with an unlimited data plan.

The other question is how to TomTom users receive this real time traffic information. The TomTom devices that support HD traffic have their own cell phones with built-in SIM cards, whose cost is covered by the HD traffic subscription, so it can download traffic reports in real time. It does not require you to drain the batteries and increase the bill of your own cell phone. The TomTom device is usually plugged into the car charger.

There's another feature called "IQ Routes" that enables TomTom to plan intelligent routes even when they're not connected to the internet, based on historical time sensitive information. Traffic on different roads has different speeds at different times of day and different weekdays, so IQ Routes measures that, and takes it into account when planning routes. Then HD traffic can add another layer of real time traffic information to make the routes even more accurate.

TomTom devices (even if they're not connected to the internet live) can record the speed you drive along the roads you travel, and if you choose to opt in, they anonymize and upload that data when you hot-sync your device to your PC or Mac (using your computer's internet connection instead of requiring a wireless data plan). Then they download the aggregation of all other TomTom user's traffic speed information. So each time you hot-sync, you get fresh traffic data based on the latest measurements of many other TomTom users.

All this data is also fed back into improving the maps, correcting mistakes, and tracking changes. Since the roads are always changing, you can get a discount by subscribing to map updates, to get fresh maps and points of interest updated regularly. We also offer traffic camera (speed trap) subscriptions, so the TomTom can warn you to slow down before you get speeding tickets.
