Lying Eyes: Cyborg Glasses Simulate Eye Expressions

ljw1004 Re:authenticity (55 comments)

If I understand, your question is basically, "why is the human brain's amygdala hard-wired to produce emotional responses in this way?"

There's no really good answer, other than "it just is" and maybe some handwaving about evolutionary psychology.

Cortana is optimized too for American accents in this release.

Not much of a problem. I have a strong English accent, and the same technique works with Cortana as speaking abroad... I just speak LOUDLY AND CONDESCENDINGLY. :)

How 'DevOps' Is Killing the Developer

ljw1004 Re:It's a Great Learning Experience (223 comments)

I've heard something similar...

If devs have to LIVE with the consequences of their bugs or race conditions or misfeatures, by having to manually fix up customer accounts, or reboot the server, or just click through too many screens, then it really focuses their minds on what are the important bugs to fix, helps them triage more effectively, helps direct their coding energy in the right place.

PS. This is only for devops work on the systems running YOUR software. If course it doesn't apply to what most people in this thread are discussing, doing devops work for code you didn't write.

OpenBSD Team Cleaning Up OpenSSL

ljw1004 Re:What about a re-implementation... (287 comments)

one reason that security-related code is best done in low level languages is that the implementer has absolute control over sensitive data. For example, consider an server which acquires a passphrase from the client for authentication purposes. If your implementation language is C, you can receive that passphrase into a char array on the stack, use it, and zero it out immediately.

That scenario actually explains why security-related code is best done in MANAGED languages using something like SecureString
http://msdn.microsoft.com/en-u... -- this way, you still have API control to zero it out immediately, but you also benefit from the fact that you can make it ReadOnly, the fact that it's encrypted, the fact that it was authored by someone who's more expert in security than you and has had more eyes to review it than your ad-hoc solution.

Continued Rise In Autism Diagnoses Puzzles Researchers, Galvanizes Advocates

ljw1004 Re:Medicalizing Normality (558 comments)

Maybe mild autism has been associated with higher wages ever since industrialization? E.g. being a factory worker who was better adjusted to city life, earning more than your peasant agrarian non-autistics? Continuing up to today where lawyers and software developers get higher salaries? That might correlate with slightly higher reproductive success. Just a guess.

(Factory worker, lawyer and programmer are roles where limited empathy wouldn't be a hindrance, and "restricted and repetitive patterns of behavior and interests" might be a help).

UN Court: Japanese Whaling "Not Scientific"

ljw1004 Re:It all winds up on a dinner table (188 comments)

I'd had it twice. The first time raw in Japan it was okay.

The second time, seared, in Iceland, it was sublime. Like a combination of the best bits of sashimi and the best bits of high quality steak, somehow unexpectedly combined in one delicious whole.

Smartphone Kill-Switch Could Save Consumers $2.6 Billion

ljw1004 doesn't add up (218 comments)

This doesn't add up...

If the carriers currently take in $2bn in theft premiums but only pay out $0.5bn in payouts, then they're pocketing a huge $1.5bn/year difference. Therefore

(1) We can expect them to lobby strongly against anything that will reduce this free money, and attempt to water down any proposed legislation

(2) If the legislation goes through we can expect them to try to gain that money in different ways, maybe with a "remote wipe services fee"...

Typo Keyboard For iPhone Faces Sales Ban

ljw1004 Re:patented keyboard technology? (205 comments)

I think that I actually agree with Blackberry on this one, though I'd think this would fall into trademark territory more than patent technology. Maybe the curved ridges on the keys somehow have a patent I guess...

Rule of thumb: IP law is so complicated that it's safe to assume that (1) TFA got it wrong, (2) the Slashdot summary and title got it wrong, (3) all slashdot posters (including me) got it wrong, with the sole exception of NewYorkCountryLawyer. I think the only way is to read what the actual filing said, and then look up patents, and then look up the claims section of those patents.

As far as I can tell, Blackberry complained that Typo Keyboard infringed one or more of:

* US Patent 7629964 - a patent about the invention of a particular angling+placement of keys on a handheld mobile device where the keys are optimally placed and angled to allow two-thumb typing. It looks like there was thought and extensive user research into figuring out that particular angling and placement. While it was obvious that some kind of angling+placement would be good, I guess no one had done the inventive work to figure out that particular angling+placement.

* US Patent 8162552 - a patent about the invention of a particular ramping of individual keys for the same end. I know that HP had beveled keys before. This patent is for a particular angling and beveling and crest and so on. Again it looks obvious that some kind of beveling is useful, but I guess no one had done the inventive work to pick out this particular angling and beveling. It looks like anyone who used a DIFFERENT angling and beveling wouldn't infringe on this patent.

* US Design Patent D685775 - a design patent which is very specifically for Blackberry's design. Design patents are for the ornamental shape of a functional item, and only apply when the design is novel and not the obvious shape for devices. I guess we didn't have the particular Blackberry proportions or layout on other devices before.

* Blackberry's trade dress. Trade dress is about the recognizable look of a product, that would let consumers readily recognize whether something is distinctively a Blackberry from its distinctive shape, colors etc.

I don't know on the basis of which of these the temporary sales ban was enacted. But I do know that Blackberry keyboards are indeed nicer to type on than any other phone keyboards I've used, and it really does suggest there was something non-obvious about their research into key placement and contours and their particular results. And I do think that Blackberry keyboards have a distinctive recognizable look. From photos, that Typo keyboard really did look a heck of a lot like a Blackberry in both its overall form. If indeed it also copied the particulars of Blackberry placement/beveling, rather than using any of the INFINITE other possible placement/beveling, then it seems like a slam dunk for Blackberry.

Mozilla Scraps Firefox For Windows 8, Citing Low Adoption of Metro

ljw1004 Re:Too much hate (200 comments)

That's not true. On Windows 8, calc.exe remains a windowed desktop app that's identical to what it was in Windows 7.

As for Freecell (and Minesweeper) they were considerably enhanced and are now touch friendly. My mother plays the daily challenges every day.

Malaysian Flight Disappearance 'Deliberate'

There's a ZERO sense to that idea. You might as well put a nuke on a completely unrelated aircraft. It's not like anyone's going to rely on visually IDing a civilian aircraft while it's on its way.

VLC Finally Launches App For Windows 8

??? VLC on win8 is free! At least, it was free when I downloaded it an hour ago.

There were a load of FALSE vlc apps on the store for $3.49 and $3.99, with similar branding, trying to scam money. Did you get suckered by one of these?

New Blood Test Offers Early Warning for Alzheimer's Onset

ljw1004 Re:As a neurologist. (86 comments)

So, it's a disease for which there is no prevention nor a cure

But there are some candidates in Phase 3 clinical trials at the moment, which all will work best if they can have an early diagnosis. I think that's why news of diagnostics tests is good. If any of these candidates pass their phase3 trials, they'd probably be on the market in 2017 - 2018.

* BACE1 inhibitor from Merck
* LMTX from TauRx

Ask Slashdot: What's New In Legacy Languages?

ljw1004 Re:Why .Net? (247 comments)

Why C# is the best language for mobile development...
http://blog.xamarin.com/eight-...
http://www.remobjects.com/elem...

* You can develop native apps in it for Android and iOS

* It is a more advanced language than the alternative languages, e.g. with its "async" language support. (which has been recently copied into Python, and is under committee review for inclusion JS and C++, but has been in VB/C# for four years already).

(disclaimer: I work on the C#/VB language design team at Microsoft. And I'm darned proud of it.)

Samsung Galaxy Glass Patent Plans To Turn Fingers Into a Keyboard

ljw1004 Re:Prior Art? (63 comments)

I can. Here's the first step. (1) ignore the slashdot summary. (2) read the "CLAIMS" section of the patent. (3) then post about it.

In this case, what's being claimed is not a laser, is not a projection, and is arguably not even a keyboard.

Ask Slashdot: What Essays and Short Stories Should Be In a Course On Futurism?

ljw1004 The Manifesto of Futurism (293 comments)

You should include the Manifesto of Futurism. It's quite moving.

1. We intend to sing the love of danger, the habit of energy and fearlessness.

2. Courage, audacity, and revolt will be essential elements of our poetry.

3. Up to now literature has exalted a pensive immobility, ecstasy, and sleep. We intend to exalt aggresive action, a feverish insomnia, the racer’s stride, the mortal leap, the punch and the slap.

4. We affirm that the world’s magnificence has been enriched by a new beauty: the beauty of speed. A racing car whose hood is adorned with great pipes, like serpents of explosive breath—a roaring car that seems to ride on grapeshot is more beautiful than the Victory of Samothrace.

5. We want to hymn the man at the wheel, who hurls the lance of his spirit across the Earth, along the circle of its orbit.

6. The poet must spend himself with ardor, splendor, and generosity, to swell the enthusiastic fervor of the primordial elements.

7. Except in struggle, there is no more beauty. No work without an aggressive character can be a masterpiece. Poetry must be conceived as a violent attack on unknown forces, to reduce and prostrate them before man.

8. We stand on the last promontory of the centuries!... Why should we look back, when what we want is to break down the mysterious doors of the Impossible? Time and Space died yesterday. We already live in the absolute, because we have created eternal, omnipresent speed.

9. We will glorify war—the world’s only hygiene—militarism, patriotism, the destructive gesture of freedom bringers, beautiful ideas worth dying for, and scorn for woman.

10. We will destroy the museums, libraries, academies of every kind, will fight moralism, feminism, every opportunistic or utilitarian cowardice.

11. We will sing of great crowds excited by work, by pleasure, and by riot; we will sing of the multicolored, polyphonic tides of revolution in the modern capitals; we will sing of the vibrant nightly fervor of arsenals and shipyards blazing with violent electric moons; greedy railway stations that devour smoke-plumed serpents; factories hung on clouds by the crooked lines of their smoke; bridges that stride the rivers like giant gymnasts, flashing in the sun with a glitter of knives; adventurous steamers that sniff the horizon; deep-chested locomotives whose wheels paw the tracks like the hooves of enormous steel horses bridled by tubing; and the sleek flight of planes whose propellers chatter in the wind like banners and seem to cheer like an enthusiastic crowd.

F.T. Marinetti, Le Figaro (Paris), 20 February 1909

We had stayed up all night, my friends and I, under hanging mosque lamps with domes of filigreed brass, domes starred like our spirits, shining like them with the prisoned radiance of electric hearts. For hours we had trampled our atavistic ennui into rich oriental rugs, arguing up to the last confines of logic and blackening many reams of paper with our frenzied scribbling.
An immense pride was buoying us up, because we felt ourselves alone at that hour, alone, awake, and on our feet, like proud beacons or forward sentries against an army of hostile stars glaring down at us from their celestial encampments. Alone with stokers feeding the hellish fires of great ships, alone with the black spectres who grope in the red-hot bellies of locomotives launched on their crazy courses, alone with drunkards reeling like wounded birds along the city walls.

Suddenly we jumped, hearing the mighty noise of the huge double-decker trams that rumbled by outside, ablaze with colored lights, like villages on holiday suddenly struck and uprooted by the flooding Po and dragged over falls and through gourges to the sea.
Then the silence deepened. But, as we listened to the old canal muttering its feeble prayers and the creaking bones of sickly palaces above their damp green beards, under the windows we suddenly heard the famished roar of automobiles.

“Let’s go!” I said. “Friends, away! Let’s go! Mythology and the Mystic Ideal are defeated at last. We’re about to see the Centaur’s birth and, soon after, the first flight of Angels!... We must shake at the gates of life, test the bolts and hinges. Let’s go! Look there, on the earth, the very first dawn! There’s nothing to match the splendor of the sun’s red sword, slashing for the first time through our millennial gloom!”

Drug halts decline in Alzheimer's disease

ljw1004 ljw1004 writes  |  more than 5 years ago

ljw1004 (764174) writes "Alzheimer's disease: researchers are divided on whether it's caused by "beta amyloid" (a peptide found in alzheimer brains) or by "tau protein" (normally used for cellular scaffolding, but can aggregate of control and destroy neurons). Today in Chicago a new drug has been anounced which stops tau aggregation and appears to have halted alzheimer-related decline in 300 clinical trial patients. Do you have friends or family who appear to be dementing? Here is an online questionnaire, part of one used in the clinical trial to diagnose dementia. (disclosure: I made the online questionnaire, and my father is one of the scientists behind the drug.)"
