Indian Mars Mission Has Completed 95% of Its Journey Without a Hitch

guruevi Re:Awesome! (78 comments)

Indians have a great standard of living... if you belong to the right caste. The problem with India's poverty is not wealth or politics, it's religious. Regardless, India has a better health care system than the US and better Internet connections.

Going to space brings about jobs and wealth. Going to war costs jobs and wealth. At least they've got their priorities straight.

The State of ZFS On Linux

guruevi Re:Unfamiliar (361 comments)

a) File systems are not OS agnostic, in servers it doesn't matter much
b) You're talking about internal RAID controllers, in a HA situation, you need external RAID controllers
c) Even with those internal RAID controllers, I've tested the LSI MegaRAID and ~1000IOPS is all I get out of it on regular spindles. The latest and greatest from LSI still gets stuck at ~200k IOPS with SSD's (~400k IOPS if you use some proprietary software) while individual SSD's get ~50k IOPS.

The State of ZFS On Linux

guruevi Re:Unfamiliar (361 comments)

The CPU and RAM overhead is relatively minimal. You can get away with very few resources, even after enabling compression.

I have a ZFS server ~5 years old right now, serving over 100 NFS and a handful of Samba/Netatalk connections simultaneously (home directories mounted on NFS, SMB and AFP for other mounts). There is a fairly steady 1000-2000 IOPS with spikes up to 100k IOPS, the machine has an uptime over 300 days, the CPU load (8 2.4GHz Xeon CPU's) hovers around 5-10% (100TB of data in 8 RAIDZ2 stripes of 8 disks (2 and 4TB), 800GB in SSD read cache, 120GB in mirrored SSD write cache, directly attached with SAS).

It will off course eat as much RAM as you will give it but for the amount you spend on a halfway decent SAS RAID controller, you can easily buy 100GB of RAM and a set of SSD's. You don't WANT a RAID controller. Regular SAS controllers with ZFS are so much faster; RAID controllers are limited by their on-board chips which are typically sub-GHz RISC (ARM, Intel, MIPS) processors - an external SAS RAID controller will cost you about $2-5000 extra and have a throughput of a few 100MBps and a few 100's of IOPS. In contrast, my setup (36 disks, 4 6G SAS channels) can give a whopping 20Gbps and 1M IOPS.

Apple Announces Smartwatch, Bigger iPhones, Mobile Payments

Apple Announces Smartwatch, Bigger iPhones, Mobile Payments

guruevi Re:Trust us with your payments (729 comments)

That's the whole point of ApplePay from what I gather. You scan the card once and then there is a challenge-response system that authenticates NFC payments. The numbers actually never enter or leave the device beyond the initial authentication.

What you are asking for is basically what they've done. The device-merchant connection gets a one-time code, your phone gets a public key to sign things with and the private stuff remains with the bank.

AT&T Says 10Mbps Is Too Fast For "Broadband," 4Mbps Is Enough

guruevi Re:I have 75M Down, 10M Up and it isn't sufficient (523 comments)

That's most likely because they're shaping your traffic to the video servers. They could easily offer you 10Gbps, if they shape every connection to 100kbps, you'll only get ~1Mbps of useful max out of your connection

AT&T Says 10Mbps Is Too Fast For "Broadband," 4Mbps Is Enough

guruevi Re:Why aren't there versions (523 comments)

Because once we define a standard, it's supposed to be set for the rest of time. You can't just "change" a standard. As with what the FCC is doing now, they're simply changing a "law" which is a hell of a lot easier to change than a standard and there is a hell of a lot of kickbacks from these providers to keep the status quo.

Also, once you have defined it, just as with current providers, the provider will just go with the lowest tier possible and call it broadband.

If anything, broadband should be defined at least 50Mbps these days, 10Mbps was broadband and around well over 10 years ago. It should keep track with storage increases - double every 12-14 months

3 Recent Flights Make Unscheduled Landings, After Disputes Over Knee Room

guruevi Re:I see two possible scenarios: (811 comments)

That is already the case though. My coworker's flight was delayed and caused her to miss the last leg of the flight, they were supposed to arrange 'alternative transportation' from there on but since there weren't enough passengers at that point to fill a bus, they simply left them all with a meal voucher. She had to purchase a 2 hour cab ride to get to her destination.

She asked the airline for compensation, they claimed the ticket to her last leg of the flight was void because the initial flight got delayed (even though it was the same company). They offered her a voucher for the cost of the last leg of the flight, then after a lot of complaining, they kept giving her more vouchers.

She sued in small claims and got her transportation back + 4x the full cost of the ticket per FAA guidelines although their attorney (which they had to fly from TX to NY) claimed the FAA guidelines only applied to the last leg of the flight and didn't apply at that point because the initial flight was delayed. But who wants to go through the hassle of small claims? How many of the other passengers simply left with a worthless voucher?

Why Munich Will Stick With Linux

guruevi Re:Can we have a [credible] MS Access equivalent? (185 comments)

If you're using MSAccess for that complex of a job, you're doing it wrong. Once SSN's and presumably HIPAA or otherwise private, protected data become involved, MSAccess or any home grown solution is the wrong solution, if not because it doesn't HAVE data protection, because it WILL eat up your database (once it grows beyond the 2GB data limit or has 2 people accessing the file at the same time)

Use a proper database on a properly managed server with properly managed controls. I'd say use FileMaker Server or MSSQL if you need an MS-centric system (Access/Excel DO allow you to use MSSQL data). But you should probably have a real developer look at it.

Could Tech Have Stopped ISIS From Using Our Own Heavy Weapons Against Us?

guruevi We shouldn't have built them in the first place (448 comments)

Everything we build to blow shit up is a drain on the economy - there is no added value.

Spend a million dollars on a bridge to nowhere is more valuable than weaponry, it keeps the jobs local even if it doesn't add value. At least the bridge won't be used against anyone.

But regardless, kill switches are a dumb idea if your life depends on it. Given the current state of software development in government/large enterprise projects like this, it will have been hacked before it even gets deployed.

And even so, a bomb/rocket is still valuable even if the ignition is busted; ignitions are easy and any random DIY with a month of free time can build a very accurate delivery system; the nazis had it figured out 75 years ago.

Tesla's Next Auto-Dealer Battleground State: Georgia

guruevi Stagnant electric car sales (157 comments)

The reason they're stagnant is because there is only one brand worth buying them from is Tesla.

Toyota/Honda has a decent lineup in the upper range with their plugin hybrids but if I'm going to plunk down 50k, it might as well be a Tesla or I can get a gas powered car with identical economy for half that price from better brands.

Perhaps one of the Germans will start entering the market with a better option but the Chevy Volt is crap, Ford and Fiat publicly state they rather don't do it, Fisker was legislated out of business, the rest of them are simply putting in a model because they have to and it shows; it's the same frame as a gas powered car with some batteries slapped into it.

Facebook Blamed For Driving Up Cellphone Bills, But It's Not Alone

guruevi Why blame Facebook? (131 comments)

The blame lies not with FB but with providers artificially limiting how much data your device can consume on a technically irrelevant time scale for profit.

1G of data is enough for ~1 hour of streaming video. So that means that you can easily burn through your allotment in a day or two for regular usage.

It's not like they can't provide you with the bandwidth, the bandwidth is not what's being measured after all. And they all collude with each other to provide the same crappy service.

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

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

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'.

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  |  more than 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 6 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

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."

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 5 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."
