She's wrong on a few points.

1. It has ALWAYS been about "Reducing Dependence on Human Workers". A person with years of hand-crafting skill is replaced by someone with months of machine-operating skill. And so forth.

2. Machines are NOT as good as she claims at predicting HUMAN behaviour. They're just getting to be better than the average human (who sucks at it).


Now machines at call centers can be used to seamlessly generate spoken responses to customer inquiries, so that a single operator can handle multiple customers all at once.

No. HUMANS can be forced to read off a script but MACHINES suck at anything more complex than "Did you say "yes"".

It all comes down to proper design and the ability to say "NO".

Security cannot be retro-fitted to a badly designed system.

The person who can demand that you support X in Y configuration NO MATTER WHAT is the person who controls your security. No matter what his/her knowledge level is.

Next, understand that you will (eventually) be cracked. Someone somewhere will make some mistake just long enough. MONITOR for that. KNOW what the regular traffic on your network looks like. PLAN for what you are going to do WHEN that happens.

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.

When someone says "I want a programming language in which I need only say what I wish done," give him a lollipop.
