If the end of the coil that is hanging is grounded (earthed), it becomes an autotransformer. As it's shown, it's a variable inductor and the disconnected end is irrelevant and has no meaningful physical effect at the frequency a spark transmitter could have reached.

This comment seems to get closer to what they actually mean in their scientific paper. But the article about it is garble and the paper might suffer from second-language issues, and a lack of familiarity with the terms used in RF engineering.

On a PC environment when you've got multiple browser windows open, IRC, email client, etc. getting constrained for IOPS is easier than expected.

An off-the-shelf SATA 840 EVO SDD hits 98,000 read IOPS, and all those tasks you mention added together wouldn't hit more than 1% of that. They're the very definition of network bound operations. The average email in my IMAP spool right now is 43KB and would take 11 4KB operations to completely read from or write to storage. Browsers site there idle 99.9% of the time. IRC? Not that I've ever seen.

Do it in a real world environment, and I'm willing to bet PCIe will show it's worth. I don't think that games will run any faster than the baseline results of no load, but I'm willing to guess it'll do better than the SATA equivalents.

I haven't bothered to look at their methodology but I tentatively agree with their conclusion: almost no desktop users would be able to tell the difference. I mean, even a HDD benching at 103 read IOPS seems spritely for most use cases. A SATA SSD working 950 times faster is as close to instantaneous as most desktop uses could ever hope for.

A guy named Amdahl had something to say on the subject. SSDs excel at IOPS, but that buys you little if you're not IOPS-constrained.

Examples of things that eat operations as fast as you can throw them at 'em: databases, compilation, most server daemons.

Examples of things that couldn't care less: streaming large assets that are decompressed in realtime, like audio or video files. Loading a word processing document. Downloading a game patch. Encoding a DVD. Playing RAM-resident video games.

It should be a shock to roughly no one that buffing an underused part won't make the whole system faster. I couldn't mow my lawn any faster if the push mower had a big block V8, nor would overclocking my laptop make it show movies any faster.

TL;DR non-IO-bound things don't benefit from more IO.

Damn, I wish I would have patented that and all its quantum magic...

I noticed that my vertical transmitting antenna often works better if I connect a horizontal wire about the same length as the antenna to ground at its base! The wire isn't connected to the transmitting side of the circuit at all! And how well it works varies depending on the length! Obviously there is some deus ex machina at work here...

Clearly you missed the bit where they invoked quantum mechanics, surely that explains away all the inaccuracies, like the fact you can already buy chip scale dielectric antennas

The thing that I really hate about Innovation Stories is that the reporter invariably doesn't understand what's going on, and invariably is easily convinced that The Obviiously Very Technical People have some very valuable invention.

+ - Automakers to gearheads: Stop repairing cars->

Submitted by Mr_Blank
Mr_Blank (172031) writes "Automakers are supporting provisions in copyright law that could prohibit home mechanics and car enthusiasts from repairing and modifying their own vehicles. In comments filed with a federal agency that will determine whether tinkering with a car constitutes a copyright violation, OEMs and their main lobbying organization say cars have become too complex and dangerous for consumers and third parties to handle. The dispute arises from a section of the Digital Millennium Copyright Act that no one thought could apply to vehicles when it was signed into law in 1998. But now, in an era where cars are rolling computing platforms, the U.S. Copyright Office is examining whether provisions of the law that protect intellectual property should prohibit people from modifying and tuning their cars."

And if no one ever determines that the innocent person is innocent, then their life is completely wasted in prison, in my opinion.

New technology like DNA, deathbed confessions, evidence found or witness statements withdrawn years or decades later can show a ruling, no matter how correct it seemed at the time to be wrong and without there being any active investigation. Sure if I've been ensnared by unfortunate circumstances or framed I'd rather you find the truth straight away, but I'd rather be wrongfully imprisoned than wrongfully executed. As long as there's life there's hope that I'll be a free man again and you can't conclusively say it won't happen until I'm dead.

Sure, it almost certainly won't happen but proponents of the death sentence is using the likely outcome to justify the means. It's like basing a warrant on the assumption that you'll find something to justify the search. Yes you've lost the presumption of innocence, but when humans make decisions on worldly evidence and testimony there'll always be a smidgen of doubt left. Posthumously clearing a name might not matter much to the dead, but it matters to friends and family and helps prove the system isn't perfect. And though it can't get better it won't be perfect and we can't turn back time, but we can give the innocent every chance they can get. And that ought to be enough.

It both increases the number of drivers dealing with a surge when a surge is happening and also decreases the people asking for rides. No, it won't increase the number of drivers total, but so what? It increases the drivers working the surge, which is the point.

The point is that you work the surge by making the service worse everywhere else. You're not able to deliver more passenger miles, you just charge more for the same fixed-ish supply. It's good business but it's questionable if the users in aggregate are better off. Then again, it does create a flash mob which may eliminate the outliers which depends on how you value waiting time. If you wait 3x5, 1x60 minutes it's less than 4x20 minutes but the latter is often preferable, since you often have to make room for a "worst case" travel time in order to be there on time.
