Processors and the Limits of Physics

guruevi Re:Go vertical! (168 comments)

There have been plenty of concept designs and current chips use 3d technology to an extent. The problem IS cooling. On a flat plane, you can simply put a piece of metal on top and it will cool it. Current chips sometimes stoke away close to 200W. With 3D designs, you need to build-in the heat transfer (taking up space you can't use for chips or communications) in between and both planes will produce equal amounts of heat so either heat transfer needs to be really, really good or you need a heat sink several times larger than the space you'd save in between the planes.

Ask Slashdot: Life Beyond the WRT54G Series?

guruevi Buffalo routers (any) (426 comments)

Some come with DD-WRT, most of their routers support it. I recommend them to clients looking for a stable business router. They are rock-stable and great support, they may not always have the latest antennae technology whenever one comes along (like 802.11ac right now). The RT-N16 was decent but is unstable even with DD-WRT (it has an under-engineered power supply).

Ask Slashdot: What To Do About the Sorry State of FOSS Documentation?

guruevi RTFM (430 comments)

I don't see a lack of documentation anywhere in the FOSS world, it's actually a lot better than most closed source software. I don't know whether you're complaining about your lack of Google-fu or the fact that software is reliant on other things. Off course, very obscure things are not well documented but that is regardless of software you use, that's when you experiment and find out what you need, write a blog post or improve the documentation yourself. But for a regular user and regular sysadmin and developer tasks, there is plenty of help available.

Driverless Buses Ruled Out For London, For Now

guruevi Re:ATO - GoA 4 (84 comments)

There is technology out there that could detect humans/animals even in the darkest portions (in tunnels etc) well in advance, outside human drivers' visual range. However whether or not that would make a difference is a big question, you can't stop a chunk of steel weighing in at 10T in a matter of seconds - well, you could (rocket boosters and whatnot) but then the meat bags inside the train would be omelets.

Driverless Buses Ruled Out For London, For Now

guruevi Re:I'm officially old I guess (84 comments)

Speech recognition has been in computers since OS/2 Warp and MacOS9. It's a 'solved' problem. However we speak much slower than we either think or type/move mouses so it's a bit of a solution looking for a problem (and with mobile there are some practical uses eg. driving a car but it's still weird to talk to a device in public as if it were your butler; heck it's weird to talk to a human butler). What isn't solved very well is understanding natural language and having a 'conversation' with a computer.

Ask Slashdot: IT Personnel As Ostriches?

guruevi Re:Simple Answers to Simple Questions (246 comments)

If I don't know any further details, I'll take it as if it were the best case scenario and someone found some irregularities and is fixing it. Irregularities doesn't mean something illegal happened, there are plenty of ways to siphon money out of a fund that don't break the law, that's what accountants are supposed to know and fix.

If something is blatantly illegal, follow the corporate policy and report as necessary to superiors and if that fails or is not feasible, authorities. Remain as anonymous as possible, do an anonymous report to HR or at least ask them to keep your identity concealed etc etc. And trust me, authorities don't give a shit about what is and isn't legal within a corporation, you file a report and nothing ever happens unless millions of dollars are going in the wrong (read: not in their) pockets. Even the corporation won't care if an accountant syphoned 100k to their personal bank account; they'll fire the dude/dudette and carry on because the bad press will hurt their stock/client base more than the 100k. For the 'regular' guy, $100k or even $1M is a LOT of money, within the billion dollar corporation this is chump change and well within their calculated losses.

How Many Members of Congress Does It Take To Pass a $400MM CS Bill?

guruevi Re:They should've removed one to make room. (180 comments)

Architecture is an important art with plenty of math worked into it, the human body in art is also a great case for both biology and math; art is important and should be a core academic subject supporting the rest however it should not be "arts and crafts" which is not art but a way of keeping kids busy.

It should be the reasons behind art, what makes a thing aesthetically pleasing, what harmonics are and how colors and light mix but how do you convince a populace that doesn't even understand half of the words in this sentence that that is what art is and why it's important?

How Many Members of Congress Does It Take To Pass a $400MM CS Bill?

guruevi Re:Sorry, but... why? (180 comments)

Math has been in the boring rote memorization exercise for decades in schools. The reason is that most people simply do not grasp the 'mechanics' behind mathematics and teachers have neither the will nor the skill to teach a subject like math. I didn't like math in school simply because they went so slow and required rote memorization of multiplication tables, axioms and rules. I even remember doing tests that were simply asking to write down axioms in text form.

Some people do grasp math and those will be the nerds that eventually become STEM students. However 75% of the population will never enter this field because they're simply not wired to understand it.

VP Biden Briefs US Governors On H-1B Visas, IT, and Coding

guruevi Re:H-1b should not be used for lower-level workers (225 comments)

The problem is that the whole computer eco-system is built on the premise that whoever is buying doesn't have a clue what the fuck they are doing. Most of the niche and custom software (think PeopleSoft which comes as a set of basic HTML blocks and a database) is something that can be built much better for a company in less than 6 months by a team of dedicated and decent programmers.

Yet, the person buying doesn't have a clue what they are doing so they throw a few million at it and 2-3 years of H1B's and overpaid (for their qualifications) contractors to come up with a system that is more broken in the end than when it started. The same happens everywhere and at every level. Desktop software: Throw a few millions at Microsoft and Dell so everyone can browse the web and receive the occasional e-mail on a system that could run Crysis 5 when it comes out in 2020 even though a Raspberry Pi would be good enough for most of the fleet. Web software: throw a few millions in the directions of Oracle and IBM in order to serve out 99% static pages.

States That Raised Minimum Wage See No Slow-Down In Job Growth

guruevi Re:Local testing works? (778 comments)

10-15%? Think more along the lines of 50%. You have to add ~15% in taxes but you don't just have to deal with SSI and taxes. You now also have to deal with accountants and lawyers to make sure everything is on the up-and-up, make sure your workplace conforms to OSHA and state standards, disability claims and benefits, vacation benefits and other employees to get coverage, FMLA, a variety of insurances to protect you from litigating employees, medical benefits...

Not saying that workers should go without all those benefits but for some that is a burden too heavy to carry if the competition doesn't follow the same rules.

Domain Registry of America Suspended By ICANN

guruevi Re:My story with those assholes... (113 comments)

They don't hijack it, the whois providers are themselves the hijackers. In case of your command line utility, it is possible your ISP simply provides their own whois (there is no requirement for whois to query the 'official' databases and it is trivial to put your own 'cache' in).

And the best thing is that most of these 'hijacked' domains are never paid for, ICANN allows for ~$0.25 (refundable) to 'reserve' a domain name. Eg. an ISP or web service may do this as a 'service' so you're sure to have it when you pay for it (with them). Then if you don't pay for it, the domain is set up for expire and goes on a feed where decisions are made (most likely an algorithm based on keywords and name lists) and then registrars are bombarded for seconds leading up to the expiration time by requests to register the domain in a similar 'reservation' fashion.

What is the best starter guide/book for beginning with OOP

guruevi guruevi writes  |  more than 2 years ago

guruevi writes "A (girl)friend of mine just started a CS course and has been dumped head first into programming with Java.

The textbook sucks in my not-so-humble opinion, the teacher just glossed over the theory, didn't really explain anything other than "just do this and it will work" (until yesterday she had no idea as to what String[] args means in the main and why it should or shouldn't be there) and has given them only a few class methods to implement, feeding them the main and tester classes so far then skipped straight ahead to "now implement the main, this class and the tester" leaving (at least one of) his pupils bewildered as to what it actually all means.

Yes, she can parrot what an object is and a string or an integer and how to write it up but she has no idea how it fits together. Constructor methods same problem, parrot the theory but no idea what it actually means and how object oriented programming makes things look different than the methodical sequential programming people are geared towards thinking.

Since I am an already somewhat seasoned programmer I can explain what everything means and it feels very natural after years of experience but I'm not a great teacher. I also like to introduce what is and isn't good practice (and where her teacher goes horribly wrong is teaching good practice such as commenting, variable naming etc.) but it all gets overwhelming for her.

Since I am not really familiar with Java (more of a P*/C/ObjC/C++ guy) I am looking for either a good guide on Java or any objective oriented programming for beginners, something where people can understand how methods/functions work, how variables are passed and what scoping means (things the textbook doesn't explain until a few chapters later, it just assumes the pupil to copy the examples)"

BREIN removes data from seized hard drives

guruevi guruevi writes  |  more than 3 years ago

guruevi writes "In January BREIN (the Dutch counterpart to the RIAA) illegally seized 8 servers from a hosting provider. In order to get the servers back, BREIN and the hosting provider reached a settlement where all servers would be returned but 4 servers BREIN claims hosted illegal websites would be completely erased. The other 4 hosted administrative data of the hosting company.

According to BREIN, the servers hosted illegal top sites (sites where data is shared among releasers, not end-users) but the owner of the servers and the hosting provider denies the allegation, the company that owned the websites that were hosted on the servers went into bankruptcy in the mean time.

BREIN settled before a judge could review the case and in return for the servers and in order not to prolong the impact on his business made the owner agree to a gag order as well. According to Tim Kuik, proprietor of BREIN, "we got exactly what we wanted" and calls the opponents lawyers a "bad loser"."

SABAM wants truckers to pay for listening to radio

guruevi writes "SABAM, the Belgian RIAA wants truckers to start paying for the copyrights to listen to the radio in their cabin. SABAM already has a system in place to extract fees from businesses for having radio's in the work area for businesses with more than 9 employees and they find that truckers' cabins are areas of work and thus infringe on their copyrights. The local politicians think this is going too far, they believe truckers need a radio for safety reasons and view a truck cabin as 'an intimate place'.

Can you come up with other places to extract music copyright remittances? Maybe you may want to pay taxes every time you take a dump as your gas may form a tune."

First known binary star is a sextuplet system

guruevi guruevi writes  |  more than 4 years ago

guruevi writes "The two stars named Alcor and Mizar, sometimes also called "Horse and Rider" can be seen with the naked eye and has been thought to be a binary system since ancient times. Using his telescope, Galileo documented Mizar to be itself a pair of binaries with later discoveries in spectroscopy showing it was actually four stars orbiting each other. However an astronomer at the University of Rochester made the discovery that Alcor is actually two stars and it is apparently gravitationally bound to the Mizar system making the whole group a sextuplet.

The discovery is surprising since Alcor is one of the most studied stars in the sky. Eric Mamajek, assistant professor of physics and astronomy at the University of Rochester, and leader of the team that found the star says "We were trying a new method of planet hunting and instead of finding a planet orbiting Alcor, we found a star." The star seems to be a cool and dim M-class dwarf star."

Brain Separates Living and Non-Living Objects

guruevi guruevi writes  |  about 5 years ago

guruevi writes "For unknown reasons, the human brain distinctly separates the handling of images of living things from images of non-living things, processing each image type in a different area of the brain. For years, many scientists have assumed the brain segregated visual information in this manner to optimize processing the images themselves, but new research shows that even in people who have been blind since birth the brain still separates the concepts of living and non-living objects.

The research, published in today's issue of Neuron, implies that the brain categorizes objects based on the different types of subsequent consideration they demand — such as whether an object is edible, or is a landmark on the way home, or is a predator to run from. They are not categorized entirely by their appearance.
"If both sighted people and people with blindness process the same ideas in the same parts of the brain, then it follows that visual experience is not necessary in order for those aspects of brain organization to develop," says Bradford Mahon, postdoctoral fellow in the Department of Brain and Cognitive Sciences at the University of Rochester, and lead author of the study. "We think this means significant parts of the brain are innately structured around a few domains of knowledge that were critical in humans' evolutionary history."

Previous studies have shown that the sight of certain objects, such as a table or mountain, activate regions of the brain other than does the sight of living objects, such as an animal or face — but why the brain would choose to process these two categories differently has remained a mystery, says Mahon. Since the regions were known to activate when the objects were seen, scientists wondered if something about the visual appearance of the objects determined how the brain would process them. For instance, says Mahon, most living things have curved forms, and so many scientists thought the brain prefers to processes images of living things in an area that is optimized for curved forms.

I just wonder where zombies and the undead would appear on your fMRI."

Regular Light Bulbs Made Super-Efficient

guruevi guruevi writes  |  more than 5 years ago

guruevi writes "An ultra-powerful laser can turn regular incandescent light bulbs into power-sippers, say optics researchers at the University of Rochester. The process could make a light as bright as a 100-watt bulb consume less electricity than a 60-watt bulb while remaining far cheaper and radiating a more pleasant light than a fluorescent bulb can.

The key to creating the super-filament is an ultra-brief, ultra-intense beam of light called a femtosecond laser pulse. The laser burst lasts only a few quadrillionths of a second. During its brief burst, Guo's laser unleashes as much power as the entire grid of North America onto a spot the size of a needle point. That intense blast forces the surface of the metal to form nanostructures and microstructures that dramatically alter how efficiently can radiate from the filament.

In 2006, Guo and his assistant, Anatoliy Vorobeyv, used a similar laser process to turn any metal pitch black as reported on Slashdot. The surface structures created on the metal were incredibly effective at capturing incoming radiation, such as light.

Guo's team has even been able to make a filament radiate partially polarized light, which until now has been impossible to do without special filters that reduce the bulb's efficiency. By creating nanostructures in tight, parallel rows, some light that emits from the filament becomes polarized. Guo is also announcing this month in Applied Physics Letters a technique using a similar femtosecond laser process to make a piece of metal automatically move liquid around its surface, even lifting a liquid up against gravity."

Pure IPTV providers in the US

guruevi guruevi writes  |  more than 5 years ago

guruevi writes "We currently have Time Warner Cable in our area but no viable competitors. We have no FiOS, we have no decent DSL (unless you call 512/128 good, we have no U-Verse. We only have TWC for Cable and High-Speed Internet or DirectTV for Sattelite. TWC knows this and thus can charge anything for no service. Currently we were forced in their All-In-One package since it is cheaper than buying just cable and internet from them. Recently the quality of the basic cable (analog) offer has been degrading to the point that there is visible pixelation and the color has been degraded to something that looks like 256 color VGA (looks like a 90's era compressed DivX) especially during peak hours. This is (I think) done to save on bandwidth since they are offering more HD and On-Demand channels and a whopping 10MBps Internet (Turbo Boost).

So I wanted to switch to digital and HD since it's supposed to be better, we payed for HD service and were forced to rent their DVR with it (they don't offer HD service without). Not a problem, the channels are decent. Now we want a second television so I have an HD television but you can't receive their HD channels without a DVR since they are all encrypted. No problem I think, I plug into the Firewire plugs on the back of the DVR which are supposed to be able to tune the box and stream it over the network using MythTV however these plugs have been (illegally or intentionally) disabled. Calling TWC doesn't help, they don't want to ship me a DVR with the plugs enabled nor do they want to ship me a cable box that can decode the HD service I'm paying for. The only solution they have is to pay for another DVR box ($120 for the box + $120 installation) and rental (~$20/month for the box + $4/month for the remote (no kidding) + taxes and fees). CableCard has recently been discontinued on the network so I can't buy a TiVo.

I think the best solution in my situation would be to dump TWC all together for cable and switch to a pure IPTV provider. The problem is however, I found a few IPTV providers outside the US (Israel, China, India, Europe, ...) that offer some type of TV channel offer (either with or without a set top box) but I can't find any that offer the US. I don't need local channels however I would like to have at least NBC (although I can get that over antenna), ABC, A&E, Discovery, Comedy Channel etc. Ideally I would be able to integrate an IPTV offer in my MythTV setup but it's not a requirement. I am more than happy to pay for a set top box rental or pre-paid as long as I can get some decent service for a decent price. My bandwidth is good and stable enough for certain HD channels (they are currently already compressed with TWC and I can stream 720p QuickTime) and I can always upgrade my bandwidth from the current 3 Mbps. Anybody that tried out some good providers or content distributors and had good results?"

Controversial wiretap law passed through the House

guruevi guruevi writes  |  more than 5 years ago

guruevi writes "The controversial wiretap law which has had quite some coverage here on Slashdot and created an outcry with people concerned about their privacy has finally been passed through the House and is now going to the Senate. The law will grant retroactive immunity to the telecom industry which has aided the Bush Administration and 3-letter agencies with illegal wiretaps and will legalize such wiretaps.

For future wiretaps, the new measure would require a special court set up under the Foreign Intelligence Surveillance Act to approve any effort to spy on Americans. Authorities could act for up to seven days before seeking a warrant — more than twice the three-day emergency period under the current secret laws and courts.

The House vote was 293-129, with 188 Republicans and 105 Democrats voting for it. One Republican voted against the measure.

Bush said the legislation will "allow our intelligence professionals to quickly and effectively monitor the plans of terrorists abroad while protecting the liberties of Americans here at home." He's also fearmongering by saying that 'the enemy' that attacked us at 9/11 will attack again and this legislation will allow

Senate Intelligence Committee Chairman Jay Rockefeller, D-West Virginia, said the bill would prevent administration officials from conducting any new warrantless surveillance. House Majority Leader Steny Hoyer, D-Maryland, said the new plan is "not perfect" but "strikes a sound balance" between intelligence-gathering and civil liberties.

Rep. Pete Hoekstra of Michigan, the ranking Republican on the House Intelligence Committee, said the intelligence community depends on "the backing of patriotic private companies."

"The telecom companies simply have to produce a piece of paper we already know exists, resulting in immediate dismissal," said Caroline Fredrickson, the head of the ACLU's Washington legislative office. She said the bill "does nothing to keep Americans safe and is a constitutional farce.""

Researchers compress 20s of music onto 1kb

guruevi guruevi writes  |  more than 6 years ago

guruevi writes "Researchers at the University of Rochester have digitally reproduced music in a file nearly 1,000 times smaller than a regular MP3 file. The music, a 20-second clarinet solo, is encoded in less than a single kilobyte, and is made possible by two innovations: recreating in a computer both the real-world physics of a clarinet and the physics of a clarinet player.

A comparison of samples of both reproductions (MP3 and this new algorithm) can be heard on the site.

Apparently they sample all physics that interact with the clarinet at speeds a human can produce (as opposed to sampling the sound it produces thousands of times per second) and then reproduce the sound. I don't know if this would be similar to MIDI but according to the researchers, even the human voice could be synthesized this way."

The 'Planet' in Planetary Nebulae

guruevi writes "Astronomers at the University of Rochester, have announced that low-mass stars and possibly even super-Jupiter-sized planets may be responsible for creating some of the most breathtaking objects in the sky.

The news is ironic because the name "planetary" nebula has always been a misnomer. When these objects were discovered 300 years ago, astronomers couldn't tell what they were and named them for their resemblance to the planet Uranus. But as early as the mid-19th century, astronomers realized these objects are really great clouds of dust emitted by dying stars.

Now, researchers have found that planets or low-mass stars orbiting these aged stars may indeed be pivotal to the creation of the nebulae's fantastic appearance. Pretty pictures and more information in the link."

guruevi writes "When I went to configure a server today on the Apple Store, I couldn't find their XServe RAID systems anymore. Apple released Xsan 2 today but silently they also replaced the XServe RAID, Apple's in-house PATA-based RAID solution with a Promise VTrak E-Class RAID Subsystem which can seat up to sixteen 750GB 7200-rpm SATA or 300GB 15,000-rpm SAS drives for up to 12TB of raw capacity. These solutions come in at $11999 for 8x 750G SATA drives, $14999 for 12TB and $18999 for 4,8TB of SAS drives spinning at 15,000 rpm So no more nicely brushed aluminum storage enclosures, hopefully they are just as simple to maintain."

TSA testers slip fake bombs through security

guruevi guruevi writes  |  more than 6 years ago

guruevi writes "But apparently it's not all that difficult. According to the CNN writeup, about 60%-75% of tests fail (as in, the investigators successfully slip through security successfully with a potential bomb. This doesn't inspire much confidence in the TSA security systems which have become more of an annoyance ever since 9/11 to any Slashdot and non-Slashdot reading traveller. This particular investigator actually has a bomb strapped to his back, gets a pat down because of a metal leg and gets away with telling it's a back support. Scary or common knowledge?"

Hip-Hop and Cell Phones Attract Girls to Science

guruevi guruevi writes  |  more than 6 years ago

guruevi writes "In order to attract girls to Science, seventh and eighth grade girls from Wilson Foundation Academy will be searching for real scientific answers to questions on topics that interest them most. As part of Science STARS (Students Tackling Authentic and Relevant Science), an after-school program at the University of Rochester's Warner School of Education, middle school girls will investigate how hip-hop dance affects balance coordination and reaction time, what the impact of hairstyling products on hair is and how cell phones distract us through everyday usage. So is this just going to be a fad or will girls really be attracted and make the 'science choice' later in life by these type of programs?"

"Electromagnetic Wormhole" with Invisibili

guruevi guruevi writes  |  more than 6 years ago

guruevi writes "Allan Greenleaf, professor of mathematics, and others at the University of Rochester first created the mathematics behind the "invisibility cloak" announced last October. In a study in the Oct. 12 Physical Review Letters, the team has now shown that the same technology could be used to generate an "electromagnetic wormhole".

"Imagine wrapping Harry Potter's invisibility cloak around a tube," says Greenleaf. "If the material is designed according to our specifications, you could pass an object into one end, watch it disappear as it traveled the length of the tunnel, and then see it reappear out the other end."

More information and pictures can be found here: http://www.rochester.edu/news/show.php?id=3012 The University of Rochester (www.rochester.edu) is one of the nation's leading private universities."
