GPS time and other atomic clock systems (TAI) are continuous but Unix time isn't. To convert from an atomic clock to Unix UTC, you must shift the epoch and run through the leap second list.
The difference between UTC and Unix time is that UTC will add leap seconds by ending a day at after 23:59:60 than after the usual 23:59:59, thereby maintaining perfectly unique timestamps. Unix time can't do that so it repeats a second.
If only there was a way for computers to send data to each other...
NIST and some other entities provide an online leap second list. There's no need for this to be manual.
USB 2 is a crude extension of a protocol made for mice, keyboards, and cheap thumb drives that were meant to replace floppy disks. There's a lot that it can't do by design. It can't transfer at high speeds efficiently and it must operate in a master/slave configuration. It could not join multiple high speed components that need to talk to each other, and that is where FireWire became the standard.
I haven't read all of the USB 3 spec but it claims to solve a lot USB 2's issues. The only downside is the fat cable and fat connector caused by USB 2 and USB 3 wiring needing to exist side-by-side. It's still only 5V so power sourcing remains a problem. Light Peak was supposed to free us from fat cables but Intel dropped the ball. It's a shame because two 18V power wires and a little bundle of fiber optics would have made for very small and powerful cables.
Has anyone checked what the mobile Chrome does? Google has your bookmarks, your downloads, your history, thumbnails of pages you've visited, your calendar, your contacts, your search history, permission to take pictures, permission to record audio, a live stream of you typing into the URL bar, your location, and it even has an "optimization" that will route all HTTP traffic through Google. Most of this is enabled by the phone's factory configuration wizard.
No nostalgia here
I was never a fan of Dolby processors on consumer equipment. Dolby NR required calibration that couldn't be provided by any consumer equipment, especially cassette tape players. What you got was pumping and arbitrary changes in volume. Various matrix encoding tricks to cram surround sound into two analog channels were a wreck too. It was fine for synthetic positioning from mono sources (sound effects, dialog, music tracks, etc) but it destroyed natural stereo. The licensing for the Dolby tech bumped up the price on everything, and no product came without it even if few actually turned it on.
Dolby wasn't cool until they started putting digital bits on film, but they were not much ahead of Sony by then.
The next opportunity is: Internet service. Telcos claim that everybody is bathing in 100+ Mbps Internet connections but the truth is that availability is poor, prices are high, shady deals interfere with connectivity, contracts screw customers, and there are EXTREME usage restrictions. Incredible amounts of money are being sucked up by telcos to provide virtually nothing, just like with smart phones before Apple and Google started kicking some telco ass. Google knows what's coming and have started providing internet services of their own but, as big as they are, they're not big enough. Apple should have jumped in too but they're still stuck on the old iPhone, and even dumbing down their other products to be more like iPhones.
Still no Bluetooth file exchange? When living in a walled garden, one should periodically check if the walls are keeping the lunatics out or keeping them in.
WiGig isn't going to make wireless mice and keyboards perform any better. It won't help portable printers and scanners that need 5VDC. I don't like the idea of running disks or video over a connection that will constantly glitch from motion in the room. What's needing this solution?
The idea behind Linked-In is great but human nature kills it. Recruiters spam for quantity. Professionals hoard senseless connections and recommendations to improve their perceived standing. The noise generated by that overwhelms attempts to get anything serious done. I kept my account lean and clean but I found no way to stop Linked-In's own HR department from spamming me with their job openings until I closed my account. Hopefully that $1,000,000,000 can buy some professional hygiene tools. (And they better upgrade Maude Ave at their new HQ so I don't get killed bicycling to work)

One datacenter isn't much of a cloud. In fact, it's more like a hosting environment that one would call a "datacenter."
No REST for the stupid
It's worse than having a durable login cookie. If the documentation is correct, HTTP GET is used to initiate significant changes to the car rather than the proper POST method. GET must be idempotent - safe to make or not make at any time. Resources with GET allow clients to pre-fetch it, cache it, asynchronously revalidate the cache, or attempt to fetch the resource in segments. This API is begging for massive malfunctions and the designer never should have passed a hiring interview.
I still haven't finished disabling all the T-Mobile, Sony, and Google shoveware that came on my phone. There's even shovelware to help you maintain a phone that's overloaded with shovelware (for a small monthly fee, of course). A clean phone could cost a lot more and be worth every bit of it from the time and sanity saved.
$15,000,000 and 2 years prison
Didn't Sony help create laws in Japan that give jail time to copyright infringers? It seems only fair that some Sony execs go to jail for stealing a patent.
Just the specs
I have to agree that Samsung is the worst. Compare any phone/tablet maker to Samsung and the features for Samsung phones completely kick butt. They have better displays, microSD, replaceable batteries, faster processors, and better form factors. Unfortunately, the Samsung phones are the least likely to work. Android developer forums and customer support forums are always full of complaints about Samsung devices failing due to firmware and electrical bugs. It's serious stuff like rapid battery death, radios going dead, touch screens malfunctioning, GPS not working, and intermittent cell reception. Their repair centers return the devices as "operating normally" when what you asked for was "working."
I see a lot of tech makes being oblivious to their customers. Apple rules at information appliances and new-tech office appliance products. Android targets geeks while still doing a good job at being information appliances and new-tech office appliances. Microsoft dominates the old-tech office appliances.
So now why are big companies screwing the best customers? Apple is dumbing down their products so much that they're becoming too incompatible with new-tech offices. Android champions HTC, Motorola, and Nexus are sealing in the batteries and eliminating microSD slots to piss off geeks. And what exactly is Microsoft's Surface RT? Commercials show them being tossed around picnic benches, laughed at in coffee shops, and clicked in and out of a tiny exercise mat. I have no idea what a Surface RT is, and memories of old Windows problems makes me not even care.
I just felt compelled to vote so that ups and downs match counts.
As for the study - It's not just human nature. Most comment engines move highly voted articles to the top, creating a positive feedback loop based on first clicks.

But the things that I have in mind for my SII would terminate it faster than the speed of data.
I've legally transferred many songs between my personal devices using the Internet for transport. I've also legally listened to purchased streams of copyrighted material. The NSA has surely duplicated a few of those streams without authorization and must be punished to the fullest extent of the law.
That's what it sounds like when you live next to an international airport and a low flying airplane momentarily reflects high power radar down at your electronics. The TV goes, the FM radio goes, your phone says Ø, and I've even had my digital car stereo lock up dead a few times.
One by one
Learn to read mail headers, learn to use network registries, and fire off abuse complaints. There are a lot of trolls, spammers, and hackers out there but there's satisfaction in kicking them off the Internet when they violate their laws or TOS. E-mail harassment and hoarding copyrighted material are easy ones. China, Taiwan, and Korea almost never have valid network contacts so it's best to stop all of their mess at the firewall.
And the sky is blue
Hijacking web pages through advertisements is old as dirt. The last time I turned off my web bug blocker, I saw that it was still happening on CNN.com and Yahoo.com. Advertisers resell over and over so the true origin can difficult to track.
I originally viewed the "walled garden" as a limitation that would eventually be solved. I awaited improved iModels but Apple had other plans. The "walled garden" is extending further and further into the desktop computers with each MacOS release. Portable files and freely available applications are deprecated in the current OS. The next OS appears to push this even harder; further restricting what applications can do if they don't run in Apple's private "sandbox". Apple is taking such drastic measures to lock-in customers that, for the first time 20+ years, I can't see my self buying anything more from them.
They never exaggerate
My Samsung S2 is rated for 18 hours of talk time and 20 DAYS of standby time. It's junk and I never use it yet a full charge on a new battery gives it 25 HOURS standby. In one year it damages a battery so badly that it powers off after 9 hours of doing nothing but checking e-mail every 15 minutes.
Re: The worst kind of cable nonsense.
Aereo sells in dense urban areas where your TV signals have been reflected and re-mixed dozens of times off the sides of tall buildings before flying in your condo window. They're not for suburban houses where a rooftop antenna is a trivial hookup for free TV.
Re: Bad written software = old versions needed = vulnerable systems
The performance tuning is different in each version of Java. For example, String.substring() was changed in Java 7 to perform very differently. That's an extremely heavily used method and the change is not welcome to many. Parsers need to stop using the String class to regain performance! Another resistance to change is that it has usually taken several years for each new Java GC to be free of critical bugs on extremely large applications.
My plan for success in the US government
1) Buy hundreds of enterprise grade routers and pocket sales commission
2) Legislate local telcos out of business to eliminate interference
3) Auction off vague but exclusive telco contract for highest bribe, um, I mean commission
4) Create expensive contracting agencies to oversee progress
5) Drain local subsidies of all funds to cover "unforeseen problems" and "regulations"
6) Say it's "almost done" and ask voters for more money
7) Leave town and repeat in another state
Ah, now I know why Silicon Valley traffic lights are possibly the worst in the world. Only in Santa Clara county will 90% of your time on the road be spent at red lights for intersections with no traffic flowing. It's to give you a few minutes to play with the car tech at every intersection.
Do the prom clothes still fit?
Apple's surge of innovation in phone tech is gone and it no longer justifies the strict rules for sellers and developers. While others are trying to make phones with the smarts of both an iPhone and a desktop computer, Apple is working on making desktop computers dumber like iPhones. Apple is still celebrating the glory of an event long gone while forgetting to tend to the present.

Re: Why the Internet clusterfucks
Another month, another research paper promising to save us from TCP. How refreshing it would be to see a research paper instead showing that new tuning algorithms don't work outside a carefully controlled test. Here are your input parameters: Ack packets, data packets. Here are your output parameters: Data packet rate, data packet size, Ack packets. That's all it comes down to. There's absolutely no way for those input parameters to indicate which output parameter is the bottleneck. You can set up a slow guess-and-check feedback loop but the required solution changes too quickly for that. Unless your OS is many years old, TCP already knows all the tricks that work. UDP is also no cure for handshake latency and TCP sessions. To not have a handshake means that hackers can request that extremely large payloads be delivered to forged addresses. QUIC requires an initial handshake and session, just like a long-running TCP connection, for security.
Honestly, the best way to speed up web pages is to block advertisers and web bugs. Google is the problem, not the solution.
There, fixed that low disk space issue!
Re: Optical archival system - where to buy from?
Data on spinning rust can be safe forever. I still have my files from a 1989 hard disk, and even a few from a 1983 5.25 floppy. Keep feeding the Drobo new drives to replace failing drives. Keep a second copy to protect against Drobo failures and human errors.
Efficiently sending TV over the Internet is no technical challenge as existing regional distribution boxes could have proxy or multicast hardware put in them. The challenge, especially in the US, is all the greedy fingers that want a cut of the money. Toll trolls can't do anything about over-the-air TV because it's direct and uninterruptible. Cable TV suffers channel outages as the media company owning the wires battles the media company owning the programs for more money. Now imagine every ISP, from mega media corp to mom'n'pop, installing a hierarchy of simple TV proxy boxes. Toll trolls would have a feeding frenzy. You'd end up with such a ludicrous mess of DRM, activation dongles, usage tracking, ad injection, and fees that it would never work.
But there's an elephant in the room, crapping on the carpet
There's public backlash against government spying and all I hear politicians saying is how hard they're working to punish the whistleblower. Diane Feinstein's buddy Nancy Pelosi keeps saying that it's all about the economy. How much money does all that illegal spying cost? I'm guessing it's enough money to give every US citizen fast Internet, cleaner energy, and a good education.
And so commences the death of Oracle. "It's too hard to get support for it," businesses will say.
Re: Just what the world needs …
What's odd about Microsoft is that they're designing a new language syntax. There's really no need for that. They could recycle C++ or Java syntax but supply it with web-specific runtime libraries rather than the sprawling and insecure ones used for applications.
It seems like when you're at the point of 30 megagram cables you want the elevator to instead climb a track. The lack of a counter weight would be a lesser disadvantage than the inertial mass of so much cabling.
What if you cut back the water, blend it until the proteins get sticky, mix in a bit of baking powder, and cook it in a skillet?
Re: Hot Mac Pro?
I was thinking of a HEPA filter attachment for allergy free computing.
Revenge of the Mac Cube
That new Mac Pro won't be so sleek when it's surrounded by a tangle of data cables, accessory boxes with noisy fans and blinking lights, power cables, power bricks, and everything else. A large silver box with lots of internal slots seems very elegant now, doesn't it? The power button is on the wrong side too. This would be a kick-ass Mac Mini but it's a total failure as a Mac Pro.
Still can't turn off the destructive Auto Save "feature". I see no mention of improving the sluggish old HFS+ filesystem codebase. That's not so Maverick.
Record this, NSA : I'd like to see a lot of the government in jail with no retroactive immunity.
RAIDing the workforce
Layoffs can't be too bad. Surely they're keeping at least one in five employees redundant.
One bar of death
Ha! Now employees can experience the overheating, crashing, radio malfunctions, nonsense roaming warnings, and circuit crosstalk gremlins in their phones when the signal is weak.
In addition to obvious points about Softbank not being Chinese, hackers would want a much faster network.
Can't be any worse
"My new wireless access point was delivered sounding like a box of rocks and bits of broken plastic are falling out the vents. I need a new one shipped with some padding."
"Thank you. Who is your internet service provider?"
H840 revision 2 would shorten nicely to "Hate 42".
No PIN is needed. Most ATM cards also work as credit cards, and retailers don't need to perform any security checks on credit cards if they're willing to pay high transaction fees.
The catch is in the contract worth $2000 - $3000 that's bound to the phone. The telco asks you to keep paying even if the phone they gave you is incapable of functioning. The telco and manufacturer are well defensed against continuous warranty repair claims. They keep your phone for two weeks each time and send it back as "operating as expected" while you keep paying the contract. The other option is legally fighting the contract. Nobody wants to risk that on a Facebook phone. (And why I will never buy from Sprint or Samsung again)

Re: A similar argument applies to Time Travel - if it were possible, they'd already have visited.
Time travel would be possible with infinite computational power. Traveling back in time would be a matter of examining the state of the universe, reversing its path in a virtual environment, and then entering that environment or overwriting the present with it. Altering the present from the past would be calculating what changes a past event would have and then applying them in the present. Altering the future would be predicting what changes would be needed to arrive there and applying them in the present. You could argue that it's not really time travel but, if done well enough, there'd be no way to know the difference. Extremely narrowly scoped examples can already been seen on the Internet, in history books, the financial market, and in good brain washing. The scope of such hacking will increase over time.
