$500k "Energy-Harvesting" Kickstarter Scam Unfolding Right Now

ldbapp Re:Actual PhD students getting slandered? (448 comments)

He did not confirm a device, though I didn't ask. He confirmed his involvement in biz.dev, and said it was only part time. He expressed personal confidence in the project, but that's all.

There was one odd thing. I sent email to him @ucla. He replied from wetaginc.com explaining that it is because iFind isn't related to UCLA. Then he offered to send an empty message from the UCLA account. I glanced at the headers of his email and found references to eigbox.net, which seems to be implicated in SPAM related stuff. It could be innocent. He may just be being careful to separate his professional activities, and his email provider/ISP may use eigbox. Or there could be a MITM thing going on. A group looking to KS scam $1/2M could certainly be savvy enough to impersonate the people who's names were stolen.

My level of curiosity isn't high enough to pursue any further. ;)

$500k "Energy-Harvesting" Kickstarter Scam Unfolding Right Now

ldbapp Re:Actual PhD students getting slandered? (448 comments)

After my post mentioning my skepticism about his involvement, I had an email exchange with him where he confirmed what the KS page says.

$500k "Energy-Harvesting" Kickstarter Scam Unfolding Right Now

ldbapp Re:Actual PhD students getting slandered? (448 comments)

Similarly: Wotao Yin, according to google, is a mathematician working on the mathematics of optimization. Yet, he is listed as a biz.dev. guy who, "leads the business and marketing strategy development". That's a leap right there. I'd guess his name has also been used without his knowledge.

Why Bitcoin Is Doomed To Fail, In One Economist's Eyes

ldbapp Re: Offer/Demand Law (537 comments)

A govt created crypto coin would have the advantage of being "official". That's all, but that's big. Perhaps it's not enough, but being "official" sets it apart from other coin.

Why Bitcoin Is Doomed To Fail, In One Economist's Eyes

ldbapp Re: Offer/Demand Law (537 comments)

I second this idea. If at some point the gov't becomes convinced bit coin is viable, they could just start their own new block chain . If they bless it with some sort of official "approval" (e.g. Their coin is legal tender for taxes), then that one can supplant any other. And as the parent comment mentioned, any sufficiently large market force can do the same. Eventually, bitcoin won't be the only crypto coin. And if the gov't can create its own competing coin, it can create two, or N, new block chains. thus, it can mint crypto currency just as with fiat money.

Ask Slashdot: Video Streaming For the Elderly?

ldbapp Sony BD-S3100 (165 comments)

This is a combo DVD/Blu-Ray wifi internet connected device. I got it solely for the blu-ray player, but discovered how convenient the internet connection is. A netflix interface is built in. The remote control even has a "netflix" button. There's a tiny bit of setup that you can do, and after that, my over-70 mother can operate it just fine. It also has interfaces for hulu, vudu, and music services like pandora and slacker built in. I used to hook my laptop up to the tv to watch netflix, but no more. There's a selection of other lesser-known services available in the interface, too.

Accessorize Your Phone With Another Phone

ldbapp Re:It's backwards (171 comments)

Yep, that's what I posted, umm, before I read your post. (Premature posticulation.) Let's start our own hardware company. There are no barriers to entry, right? ;)

Accessorize Your Phone With Another Phone

ldbapp A nugget with a menu of optional interfaces (171 comments)

What I want is a computing nugget that I can carry in my pocket (on a necklace, whatever), and then carry any number of different task-specific interfaces to it. You don't even have to carry them. Just walk up to your desk, and your keyboard and monitor connect and you have a desktop. Pick up your "smart-phone" interface, and go. Pick up your candybar interface and go. But all the computing and storage stays the same. It's your cloud in your pocket. Sell me that HTC.

Ask Slashdot: What Would It Take For Developers To Start Their Own Union?

ldbapp Agents, not unions (761 comments)

What tech talent needs are agents, not unions. That is people to represent them in negotiations who are skilled at negotiating, and motivated to get a good deal. Very much like entertainers (actors, singers, sports stars). The agents focus on the "business" while the talent focuses on delivering value. This is especially true in job interviewing situations, especially when interviewing with a company that has a HR department. They have advantages in that interaction that are unbalanced. I personally would love to have an agent. The idea has it's hurdles, but no more so than the idea of starting a union.

Ask Slashdot: What's Your Take On Stand-Up Desks?

ldbapp Desk + short stand + shelf (347 comments)

I made a standing workstation from my existing desk, a short (~14") stand for my keyboard and put my monitor on a shelf above the desk. I even made the stand from salvaged materials around the building. You could do it with a small plank and 4 2x2" legs.

Are Brain Teasers Good Hiring Criteria?

ldbapp Re:Well, they're a good indicator of intelligence (672 comments)

Hmm, this question is relevant to the few people, like me, who've found themselves in non-tech positions and wanted to move back. We even had a post here about this recently (here). The interviewer may have a legitimate concern about why your switching back, and whether you will follow-through or flip flop again.

Thin Film Transforms Any Surface Into Touchscreen

ldbapp Re:This is an INPUT device (81 comments)

Actually, you don't need a screen, but if you stretch your definition of "something like that" you're on the right track. We have lots of input devices that don't have screens attached: doorknobs, handles, tuning knobs, buttons, switches, pedals. This could be imagined as an alternative to all of them. Put it on a piece of glass and you have an input device that lets painters "trace" pictures from real life, just like the renaissance masters.

Camera Lets You Shift Focus After Shooting

ldbapp Re:kinect + infinite depth of field + post process (155 comments)

To a degree. Kinect has limited range on depth sensor. Camera image is from exactly one POV, so you can't get the micro-movements you can with their camera.

Ask Amir Taaki About Bitcoin

ldbapp Re:Bitcoin's economic model (768 comments)

Yes, I think it is inevitable that we'll see competition from big banks, Visa, Mastercard, and their brethren. Eventually, governments.

Ask Amir Taaki About Bitcoin

ldbapp Re:Question: Economic expertise: (768 comments)

"Inflation steals wealth". Totally agree, and I think it's even worse than that. I think inflation, at least in part, reallocates wealth directly to those who earn profits (stockholders for the most part). Thus, inflation steals from those who can't invest (the poor) and gives to those who can (the rich). For that reason I agree that inflation is immoral.

Ask Amir Taaki About Bitcoin

ldbapp Re:Question: Economic expertise: (768 comments)

You make a good point about how things play out in practice. I don't know yet how much I agree with it, but it is a good point. Quibble, your example is bad. Food is a necessity. Other things can wait. Under deflation, purchases will be deferred and economic activity will slow. With "small enough" deflation, the tendency might be smaller or, as you say, hard to even notice. Still, at some rate of deflation, it will have negative effects. The main point I take away from your post, though, is a behavioral one. If inflation or deflation is small enough to not be noticeable day-to-day, people will likely act more like it isn't happening.

Ask Amir Taaki About Bitcoin

ldbapp Re:Bitcoin's economic model (768 comments)

I totally agree with your post. I will add, though, that the proposal to let the number of coins increase to keep inflation near 0 is not easy. That is the job of the Federal Reserve, and we have a whole governmental entity devoted to it. If you could solve that algorithmically, you'd have a Nobel Prize. It is the right thing to do; it's just not easy. That being said, does the math behind bitcoin depend on their being a hard limit to the number of coins? Could I start my own foocoin (i.e. a new bitcoin root) with a larger limit? At what point does the cryptography break, or does it? Can I have no limit? If it is the case that you can start your own bitcoin root with no limit on the number of coins, then eventually the government will do so, declaring by fiat that that electronic currency is now the official electronic currency (and probably also by fiat equivalent to a physical unit (dollar, dime, penny, whatever)). Thus, I predict that if and when electronic currency starts to become generally accepted, the government will start its own.
