Step 1: Work on hacking (at the very least gathering extensive info about hacking) various militarily and safety-sensitive systems
Step 2: Boast about it, publish lots of findings and clues for others
Step 3: Piss off government of country where you are resident
Step 4: Get multiple private warnings from govt to keep your nose out
Step 5: Repeat steps 1 + 2
Step 6: Be surprised when govt gives you a slap.

...is that consistent indentation makes code vastly easier to read and much harder for bugs to hide in; I imagine pretty much everyone nowadays uses auto-indentation when writing C code, which if course is curly-bracket based. If you use "GOTO" suddenly your indentation doesn't match your program flow; it's asking for trouble.
For the same reason I try to avoid doing a "RETURN" in the middle of a function where reasonable (if I need to bail due to an error etc I try to do it right at the start of a function before any of the meat)
That just leaves "BREAK" as a program-flow-modifier and I can live with that just fine.
I don't think I've _ever_ used GOTO in several decades of programming C.

I got as far as "... setting PHP config options.." and your issue became clear.

I'm a fairly well-qualified PHP hater having spent/wasted several years on it. Anyway, Vagrant is excellent. If you were to see the light one day and say use Python, you'd be using virtualenv, which would also greatly reduce your pain.

Completely disagree; having spent decades writing in many languages, when I first used Python I thought "WTF this enforced whitespace stuff is ridiculous" - for about two days, then the lightbulb went on in my head and I realized the supreme joy of having everyone's code use the same formatting; It's a huge win for code readability. IMHO the syntax doesn't suck at all; it's very productive, concise and clear IMO.
Python is also (with some corner cases) extremely portable; I switch runtimes between Win/OSX/Linux all the time and the code Just Works.
It's not an absolutely perfect language but it's damn near close enough for me.

I'm still (very regularly) using my 2013 Nexus 7 and my kid loves her 2011 IPad and they both work perfectly. Tablets age rather well; performance and display res have been more than good for several years, and they don't get dropped down the toilet/left in a bar as much as phones.
It would be much more useful to see data from Apple/Google on daily device usage...

My Comcast cable connection is fucking fast and regularly gets faster. I noticed 100Mbps downstream a couple of days ago - good thing I purchased a router with gig-e - when I'd tested it a few months earlier I was clamped at 60Mbps which was still in the "doesn't-suck" category. With that kind of performance (and excellent reliability) I just can't hate them.

Did he say if he'd seen a working device, or confirm anything other than that it was him that appears on the KS page? Verifiable details from the creators are exceedingly thin on the ground. If you'd like to screencap your email and post a link to the image, that would be great. Thanks.

Wotao popped up (long ago) on the KS comments thread and basically said "I'm an investor but I can't really talk about anything". He also replied to direct emails to his uni email, confirming his involvement. One person who contacted him, reported him (not seen the email) as admitting he's not yet seen a working device.

I think he probably got pulled in as an investor (and to add credibility) and probably now rues the day he said yes. We'll see. Either way, at this point Google searches won't forget his involvement.

The thing also needs (most of its) power to run a Bluetooth receiver (+accelerometer), which typically uses 10-15ma @ 2V (=20-30mw) when in _receive_ mode. The duty cycle is short but waking up every 5 seconds to see if the tag is being pinged isn't typically something you'd power with leprechauns (unless they were made of lithium).

err... whose claims are unverifiable?

Wetag's? Sure, they're pretty sketchy. Practically no hard info except two wack pseudo-science documents and some nice photoshop work. No pics, no demo, no nothing (so far).

Mine? Errr... well, there's a ton of links to source material throughout, there's links to other people who think the same way (and did the math also), there's facts, figures, references, etc.
If you didn't click any of the links, do any Google searches, look at the iFind site or pay attention in math or physics class in highschool, then.. yes I suppose you find them unverifiable. Tell you what, I promise, cross my heart, it's all true. Does that work?

What you say is not plausible; how do you think any radio-activated device receives the "I lost you" signal? In practice it's far from "dormant 24/7"; it's completely deaf to any signal until it turns on its high gain radio which takes typically 10-15ma. The tag must be constantly waking up and consuming power (even if, as with BTLE, it's possible to set the gaps to e.g. 5-10seconds and the "on" time is very short).

Without trying to be unduly rude, you're 25% informed yet 75% confident in your knowledge, which I suspect comprises large portion of backers of this project.

Either do a little research (e.g. look up the math and/or read the datasheets for BTLE chips - all provided in the RTFA's google doc) or... go order a pack of 10 iFinds. . :-)

FryingLizard writes: For a while I've been following the saga of the Kickstarter "iFind" Bluetooth 4.0 tracking tag. Nothing new about such tags (there are many crowdfunded examples; some have delivered, some have disappointed), but this one claims it doesn't require any batteries — it harvests its energy from electromagnetic emissions (wifi, cell towers, TV signals, etc). The creators have posted no evidence other than some slick photoshop work, an obviously faked video, and some easily disproven data and classic bad science.
So far they've picked up half a million in pledges. With six days to go until they walk off with the money, skeptics abound (10min in) including some excellent dissections of their claims. The creators have yet to post even a single photo of the magical device, instead posting empty platitudes and claims that such secrecy is necessary to protect their IP.

Using just their published figures, their claims are readily refuted, yet still backers flock in. Kickstarter appear uninterested in what can only be described as a slow-motion bank robbery, despite their basic requirement to demonstrate a prototype.
It seems self-evident that such scams should not be allowed to propagate on Kickstarter, for the good of other genuine projects and the community at large.
Skeptics are maintaining a google doc with many of the highlights of the action.

Bring your own popcorn and enjoy the show.
