Apple Doesn't Design For Yesterday

guruevi Re: I don't follow (369 comments)

Things like buttons and menus are automatically resized to fit the text (unlike Windows where about a decade or two ago you sometimes had to draw your own buttons).

These days for pretty much any OS: If you follow the design recommendations at least, your UI will be forward compatible. If you use your own or deity forbid use an entirely different API that does require fixed dimensions (eg the way Java does) you may get some weird looking apps.

Internet Companies Want Wireless Net Neutrality Too

guruevi Re:Wireless bandwidth is limited (38 comments)

In mobile, you can invest in newer technologies, more spectrum and better antennae. There is quite a bit of bandwidth available in the licensed spectrum, the spectrum is actually just as big for wireless than for copper and fiber. And precise direction of specific channels is also being worked on.

Internet Companies Want Wireless Net Neutrality Too

guruevi Re:Can we talk about two things at the same time? (38 comments)

QoS has nothing to do with net neutrality, it merely signifies what the sender would prefer to be done (when prioritization is necessary) among it's own packets. If I want to prioritize SSH and VoIP, then I'll set the necessary bits so that when I fill the bandwidth with other stuff, those tend to get priority.

QoS is perfectly possible within a neutral framework. The providers treat each customer equally, if the customer wants certain aspects of it's own traffic prioritized, it could do that without impeding the rest of the traffic.

If Your Cloud Vendor Goes Out of Business, Are You Ready?

guruevi Re:You don't need the bandwidth (150 comments)

You must have missed the last bubble or you are very naive. Whatever your 'cloud agent' promises you is false. These types of companies go bust and disappear in less than a day, the company will have let the service degrade so far by then that a single hosting company unplugging a system over non-payment topples the entire infrastructure. And the provider itself won't have told anyone it is going bust, most likely it will have stunted with pricing in order to get more customers, loading their systems even more.

And hosting companies don't release data to customers-of-customers, they want their money and these days the cloud providers themselves are renting from other cloud providers; If Dropbox were to stop paying Amazon, AWS would automatically wipe and reassigns the entire system a short period after they shut down the service. Legal action takes years to resolve, not a single provider I have ever worked with will maintain a system for years on their own dime in wait of a legal decision.

If Your Cloud Vendor Goes Out of Business, Are You Ready?

guruevi Re:Local Backups (150 comments)

This is where the bubble lies. 1TB of raw data storage costs ~$90 these days without power, maintenance, installation, support, data transfer, failover/redundancy/backup... over 3-5 years (the usable life of these drives) at current market prices, you should probably calculate close to $1500 to store and maintain 1TB of data that is properly backed up, redundant and available.

The current cloud providers (Microsoft included) are counting on you NOT using your storage beyond 5-10%. Once everybody starts using more than 15% of their allotted storage (which is inevitable given the increasing amount and sizes of stuff we store) someone will have to pay up.

I do maintain the in-house storage where I work. Even at the lowest market prices and the volume we have (currently ~200TB of usable storage), we are this year looking at a cost of ~$200-300/TB investment just in bare hardware and those prices really haven't dropped over the last 5 years because even though raw storage has dropped somewhat, the hardware to support them has not, replacements for failed disks need to come out of that budget and we need ever more and faster interconnects (larger RAM caches, larger SSD caches, faster SSDs, gigabit to 10g upgrades, SAS interconnects from 3Gbps to 12Gbps) to maintain equally speedy access to all parts of the storage for an increasingly growing and demanding user base.

The Subtle Developer Exodus From the Mac App Store

guruevi Re:Forgot the biggest one: Money (229 comments)

The "computer you already own" is not a fair comparison. I "already own" a Mac therefore Mac/iOS development to me is free.

If I had to target Windows-specific platforms, I'd need a Visual Studio license ($2000) and a Windows Server license and a Windows SQL Server license ($2000) and a Windows computer ($2000) and then the target device ($1000) and a Windows server ($250/month).

But that is just part of the investment. If one were foolish enough to invest in Microsoft ecosystems, they'd be out more than $1000 on licensing alone and that cost simply gets carried forward to the customer. I grew up with commercial Unix, Microsoft, OS/2 etc ecosystems, $0.99 applications were never the norm.

Why the FCC Will Probably Ignore the Public On Network Neutrality

There are two parties: money grubbing corporations looking to maximize profit by double dipping and "the people" that require net neutrality in order to be able to build their future on it. Sure, the party that donates the most money will win.

Your equipment cannot be incompatible with an unlimited data plan. Data transfer limits are artificial profit boosters, there is absolutely no technical reason they can't give everyone unlimited data transfer.

The great thing about grandfathered plans is that they are contractually obligated to provide the service to you. Don't give it up unless you can move to a more customer-friendly provider that does give you unlimited data.

Will Windows 10 Finally Address OS Decay?

guruevi Re:Betteridge's law... (577 comments)

I've never seen either a Mac or a Linux box suffer from 'decay'. The box will work progressively slower compared to newer, faster systems which you may get used to eg. at your job but I've never seen the box slow down any measurable amount (unless of course, the hard drive is getting close to full etc). Windows on the other hand simply slows down due to updates and antivirus getting heavier and heavier, Windows machines will also fill their own hard drives (I manage some boxes that have been installed when XP first came out, even with minimal user data, the machine has gotten cleaned up multiple times due to a full hard drive (mainly logs, updates and system restore data)

Not Just Netflix: Google Challenges Canada's Power To Regulate Online Video

Not Just Netflix: Google Challenges Canada's Power To Regulate Online Video

guruevi Re:In US, restrictions based on finite RF frequenc (109 comments)

The 'spectrum' or bandwidth of the Internet is virtually unlimited though. You just need to put in bigger pipes and even the smallest of the pipes you can currently get at an IX (1Gbps) can easily carry 1000 simultaneous viewers.

The ISP's only have exclusive rights to the last mile because we (the people) let them. For the most part, "the people" paid over and over again for this last mile as well as all the other miles (both phone and cable) through regulatory fees but either is being monopolized by a single provider. There is no technical reason that several providers couldn't offer you the 'last mile' connection. It's being done in several European countries where you have a pick of providers to offer you the last mile.

Why does your life or anything at all have to have meaning? In the grand scheme of things, your 1-in-a-billion life form on a speck of dust in the middle of an average galaxy is insignificant. Absence of proof does not mean we can just instantiate a random object to explain things (Bertrand Russell's teapot).

You can devise a scientific test for love if you define what love is. Enjoyment is also relatively easy to explain in regards brain chemistry. You are free to believe what you want but what is the meaning of believing something you can never know for sure?

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'.

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  |  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

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."

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  |  about 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  |  about 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."
