Comment No Child Left Alone... (Score 2) 684

made things a lot worse. When my oldest (who is actually good at math) went to school, he never got in trouble because he'd get some A's, a few B's and occasionally he'd even get an F... by now, math and other subjects are so dumbed down that any reasonably smart person gets straight A's - and suddenly you're being punished for being too smart... In the end, we need kids to fail more in every way.

Comment Re:after seeing what happened in Egypt (Score 1) 339

I can't remember anyone recently claiming that the US was a democracy... House members voting against what their constituents want, presidents signing clearly unconstitutional bills into law and the supreme court refusing to hear important cases? Just cause the president belongs to the democratic party, doesn't mean our formerly great country is still a democracy...

DIY Synthetic Aperture Radar 118

An anonymous reader lets us know about a DIY synthetic aperture radar built for $240 in parts (give or take). Here's PDF slideware from the Ph.D. student's research. "Using a discarded garage door opener, an old cordless drill, and a collection of surplus microwave parts, a high resolution X-band linear rail synthetic aperture radar (SAR) imaging system was developed for approximately $240 material cost. Entry into the field of radar cross section measurements or SAR algorithm development is often difficult due to the cost of high-end precision pulsed IF or other precision radar test instruments."

Comment simple != good (Score 1) 344

I like the touch surface but that "simple" window manager is just that. Simple. Too bad that there is a difference between simple and better. Just like a skateboard is simpler than a car doesn't make it more suitable to go to the grocery store with.... After all that talk of "lets increase interactivity because you can't reduce 10 fingers to one x/y coordinate" I think its a little strange that they then go to "lets reduce x/y window layouts to just x"...

In the end it just looks like an effort in changing things just for the sake of change.

Comment DIY or it will be broken (Score 5, Interesting) 183

Any method you use can be broken. Your only chance is to reduce the likelihood that your site is worth the effort.

Basically, if you use a common solution - no matter of FOSS or commercial - then there will be a thousand other sites that use it too. This attracts attackers because they know when they hack it once, they can re-use it.

However, if you handcode something, no matter how primitive, it likely lasts a lot longer because nobody bothers hacking into your site...

Of course that doesn't work if you have a large site like myspace - there, a single site is worth the effort by itself.

Anyway - then there are two things - a really fast moving animated gif and silly things where you ask people to identify items usually work.
I help out with a site that randomly takes five pictures of cats and dogs and it asks you to identify which of the images contains the highest number of kittens... We barely ever get spam through - and that with almost 20K attempted submissions by non-humans a day makes us pretty happy

Intel

Submission + - Intel X38 High End Chipset Launch and Benchmarks (hothardware.com)

MojoKid writes: "Though many leaks of the product have been circulating for some time, Intel officially took the wraps off and launched their new X38 Express chipset for the high-end desktop motherboard market. With this launch, the Intel desktop chipset line-up gets a new flagship. Intel's new X38 chipset encompasses all of the technology advances that have made the P35 a success and adds a slew of new features designed to increase memory and graphics subsystem performance, like PCI Express 2.0 SerDes and Intel Extreme Memory technology in the new X38 MCH. The Asus motherboard tested in this article at HotHardware even features an embedded Linux-based OS that boots in a matter a seconds."

Submission + - Fans or No Fans for Silent PCs

An anonymous reader writes: Can a PC with a fan ever be made quiet enough? Is it enough to use a big fan and run it very slowly? Is the best solution a huge heat sink made of aluminum or copper that runs on convection? This article examines the question of how to make a computer quiet enough to sit proudly in the living room without drowning out the movie playing on the TV next to it?

Submission + - Full sized Transformers robot made from a car

Gary writes: "Two guys from Nanjing China have built a 15 feet tall Transformer robot using parts from a Citroen C2 car. Weighing in at 600 kgs it cost $8000 and took them 3 months to complete. Unfortunately it cant move or transform but nonetheless it is super cool and the closest thing to Bumblebee. It uses original Citreon C2 lights and tires; the rest is hand-sculpted synthetic resin, glass, and metal."
HP

Submission + - Hewlett-Packard is looking for user feedback

Maximilianop writes: Hewlett-Packard is staring a new marketing campaign valued in $300 millions called "What do you have to say?" which is related to HP's newer move on web based printing services which they coined the Print 2.0 name to.
This strategy pretends to speed up the company's capacity to capture a significant portion of the 53 trillions prints expected for 2010.

Submission + - Guh-Guh-Guh-Google and the Jets

theodp writes: "Continuing their tag-team reporting on the Google execs' penchant for expensive jets, the NY Times has confirmed an earlier Valleywag report that Larry, Sergey, and Eric have added a Boeing 757 to their fleet, which already includes a widebody Boeing 767 and two Gulfstream Vs. While the Google founders and CEO are still tight-lipped on the subject, NASA responded to the Times' Freedom of Information Act request by releasing the text of a July agreement between NASA and H211 LLC (pdf-17.2MB), a company controlled by Google's top brass. The agreement requires that the Lease be kept confidential and alludes to an earlier deal NASA made with publicly-held Google ('Tenant is beneficially owned by the principal executives of an entity with whom Landlord has a programmatic, collaborative relationship and which plans to establish a physical presences at the Property'). A Google spokesman said the company does not have a relationship with H211, but did not opine as to whether his bosses did a good job of Avoiding Conflicts of Interest."

Submission + - Third-world economies sustain global warming (nazi.org)

National Socialism writes: "A climate-change expert says that spiraling economic growth has accelerated greenhouse gas emissions to a threshold not expected for at least another decade, and that its potential effects are devastating.

[ All those people who couldn't invent technology, but had it taken to them from a mixture of pity and desire for new markets, are now wanting to live like American suburbanites. They outnumber us 8 to 1. That's how much bigger global warming is going to get. Stop foreign aid and multiculturalism now! ]

Submission + - NetBSD boosts MySQL performance (feyrer.de)

hubertf writes: "Andrew Doran, who was recently hired by the NetBSD project to work on NetBSD's SMP implementation, has done a lot of good work, and he has merged some of his work from the vmlocking-branch into NetBSD-current. Effects of this are that time for build.sh on a quad-Opteron went down by ~10%.

Andrew also updated his previous benchmarks, and posted about his recent results: ``Most of the sysbench runs that I've seen to date have sysbench running on the same machine as the database. That's a good test but with the exception of small installations and out-of-band activity, production setups rarely look like that. So I ran sysbench itself on a seperate dual core system.''

There are images that compare NetBSD 3 with NetBSD-current (where most of Andrew's changes are now), and NetBSD-current compared to Linux, FreeBSD, and OpenBSD.

The original benchmarks didn't include Solaris/x86, so Jaime Fournier sat down and repeated the test (on a single system). The results show that NetBSD beats Solaris by ~25% in the ReadOnly test, and that they're about on par in the ReadWrite test, with NetBSD kicking in earlier WRT the number of client threads, but Solaris keeping up longer before they both degrade. The courves are quite similar, and my guess is that there is some room for finetuning there."
