guruevi Re: BTC Insured? (69 comments)

Please correct me then. After a bank robbery, the notes' serials get marked in a database and when they go out of rotation they are destroyed, the bank gets a new bag of notes and the FDIC assures that whatever happens your money is recovered - through another bank if necessary.

The entire economy is not backed by bullion in a bank's vault, 'losses' in the digital side are simply recovered by rolling back statements. If your account gets hacked and the money is transferred within the country, it can simply be recovered by transferring the money back because all the accounts fall under the same 'governance', even internationally there are some agreements for returning stolen money. If a 'mule' is used, the mule's balance is going to go negative and thus someone, somewhere will be indebted to the banks (whether it is the victim, a mule, the insurance company or the criminal). When insurance companies have to recover the money, they will either get it from the feds or lend the money somewhere (depending on the type of insurance and your jurisdiction - eg. in Europe, a lot of the insurance pools are backed by the government which makes the actual payments)

Cryptocurrency cannot be recovered or re-issued like bank notes can. You cannot have a negative amount of cryptocurrency because it is decentralized and supposedly anonymous. There is no governing agency or international agreement on recovering stolen cryptocurrency, no agency can just issue more currency and subsequently recover it at a later time. There is also a limited supply of them and creating them is costly so it is not feasible to simply have a stash somewhere just for insurance purposes because you would only accelerate the devaluation and instability of the system (if someone holds like 1/3 of a cryptocurrency they can technically 'cheat' the entire system)

Winklevoss Twins Plan Regulated Bitcoin Exchange

guruevi Re: BTC Insured? (69 comments)

The insurance is the least of their problems. For a good fee anything is insurable. The problem lies in the replacement. Banks/Feds/Insurance when losing money just replace the number in their databases or print the money, no insurance company nor bank nor the Feds actually has a reserve of cash to cover all their accounts in case of a massive hack that empties all their accounts. Not as easily done with cryptocurrency, once it is gone you can only replace it with more cryptocurrency. So you actually need to stash or be able to lend the insured amount instead of just relying on someone to bail you out with fake money.

Is D an Underrated Programming Language?

guruevi Re:Gotta react to the market (370 comments)

So-called readable and simple code is usually the least powerful because there is more time spent on it's semantics than what it actually has to do. Sometimes it gets so simplified that more complex operation require loads of customization to make something perform well (eg. by building additional C libraries -> see Python or Ruby) so it just is simpler to just do it well the first time around.

The Tech Industry's Legacy: Creating Disposable Employees

guruevi Re:Disposable Employees also in turn create.... (261 comments)

Bad credit scores usually means you're bad at managing money and thus more likely to steal and/or be less productive.

You don't need debt to have a good credit score. My credit score is perfect and I barely have had debt (besides a mortgage and a car payment). A good credit score means you are on time with any payments and not going into sudden debt (eg. overdrawing your accounts).

You just have to live within your means, I have gotten heavy hits to my income but I didn't keep spending the same amount of money, therefore I have a good credit score.

Regardless, HR drones shouldn't be checking people's credit scores, if I were in the hiring process and got alerted that the company pulled my credit score, I'd sever my ties with them anyway as I do with any company that has pulled my credit score without permission so far.

SystemD Gains New Networking Features

guruevi Re:Put away your pitch forks (552 comments)

systemd is fine if you don't want to fiddle with anything. It is great for the current cloud/virtualization hype because it doesn't use arcane text files which are different for each daemon but rather everything is uniformly structured so you can spin up entirely self-automated datacenters with a few presses of a button in a web interface. If you want to change your hostname, you issue a command and everything that supports systemd now has your new hostname.

However if it breaks, it is bad. Things are a mess for humans to read or change, it seems to be entirely built to be used in purpose-built GUI's and web interfaces. It has or will become the registry of Linux. If you want to use something that's not systemd-aware you're either stuck encapsulating old scripts in systemd scripts or building an entire infrastructure of dependencies and requirements around the daemon.

Ask Slashdot: High-Performance Laptop That Doesn't Overheat?

guruevi Re:Never had such issues (325 comments)

The thing is that a quality laptop (which Apple is one of) will continue to work at full load. As the OP stated, "others", especially custom builds have random issues ranging from shutdown/reboots, severe throttling or even hardware damage if you keep them at that load for a while. There are few laptop builders, even big names, that take care in what they put together.

Dell is one of those that will mash together a laptop, sometimes even with a full-blown desktop processor and whatever else you can specify without actually knowing it will work. IBM used to be a good name, Lenovo not so much anymore, Fujitsu-Siemens is/was a good name a few years ago at least but haven't had an experience in years, Asus is decent but their cheaper models are hit-and-miss. HP, Toshiba, Acer, ... stay away from those. There are/were some companies that will custom-engineer a model and test configurations for you but you will pay a hefty premium.

There exists no PC that costs $300 that will match up to a $2k Mac. Even if you plunk down $700 for a Mac Mini with AppleCare, it will be hard to find a similar machine with a similar service contract (think Dell Gold Service Contract).

Apple will come to you within 24h or ship you a new machine overnight but even after the warranty expires you can still call them and they will answer you. I have dealt with Dell, HP and Lenovo, it doesn't even come close.

Ask Slashdot: High-Performance Laptop That Doesn't Overheat?

guruevi Never had such issues (325 comments)

I don't know what you're doing with your laptops to cause such issues, are you working in the Sahara?

There are plenty of laptops out there but if you want a somewhat decent one, go for a Macbook Pro. Sure they're a bit more expensive (although not as expensive per feature as Dell) but I haven't had issues with them doing serious dev, cross-compilation and heavy computation (MATLAB, Python etc) work that can take 100% of all cores for days on end.

If you need desktop performance, get a desktop or get the building/compiling to work on your compile farm. A laptop with a desktop processor will overheat/melt/break and there are plenty of builders that will mash together whatever you specify without any real testing. And "boost" speeds are just that, they're only there to boost the occasional spike, physics will take over at some point. For the work you describe (prime calculations) you'll get much more efficiency out of a decent set of servers and have your coders check in their work after which a bot will automatically attempt compilation.

UK Government Department Still Runs VME Operating System Installed In 1974

guruevi Re:Modern Technology (189 comments)

Depends on what you declare as modern. I have a Sun UltraSPARC box from the mid-90's which is still used to cross-compile things. Some things just stick around especially in government and research but also in established businesses, things are kept alive for decades because there is no funding to replace it and for most projects the people that maintain it are cheaper than establishing a new project.

This is mainly due to the inbreeding and subsequent incompetence on behalf of the people in charge of finance and IT but also incompetence on behalf of the other managerial staff to recognize that those people in charge are incompetent.

To this day there are very few projects in large organizations like governments, schools and old businesses that include line items for security, maintenance and replacement. Most managerial types still think that solutions are a one-time cost and that, like machinery, it will run fine as long as a mechanic puts some oil and parts in it and when they need something faster or better, they can simply sell or reuse the old 'machine' and recoup 50-80% of the investment in the 'faster' machine.

Google Researcher Publishes Unpatched Windows 8.1 Security Vulnerability

guruevi Re: 90 days to fix (129 comments)

Really? Any coder able to find issues like this should be able to fix issues like this if they have the proper source code. Most issues are trivial to fix, substituting an unsafe call with a safe(r) call (eg. strcpy vs strncpy) is often enough to fix most issues.

Sure there will be some side cases where it is really hard or there may be better solutions than your patch (eg. I recently found a bug in the MariaDB optimizer which leads to bad data being returned) but then at least if the product on top of it (CiviCRM and Drupal in my case) is also open source, at least I can modify the query to fit my needs even though both Drupal and CiviCRM people say 'not our problem'.

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

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 5 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

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."

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 7 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 7 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."
