Comment Re:Makes forensic avoidance simple (Score 1) 145

Completely missing my point. Assume that datamining a la NSA, FBI, etc, actually worked to protect the citizenry from thoughtcrime before it becomes realcrime. Thus, the best way to avoid that worm, if you wanted to commit a crime, would be to delete all your social media accounts so they can't even get a network diagram for you, let alone posting bullshit rants about whatever you intend to use as your justification for going crazy and killing people. Of course, the actual fact is that predictive analysis like this is worthless, because humans are non-deterministic creatures.

Comment I work at exactly such a startup (Score 2) 274

I'm working at a similar second-stage startup (has had significant second/third round investment but still very young). I'm turning 40 this year [yay birthday vacation to Chernobyl!], there are a lot of young'ns in the office. I came from a Fortune 500 company full of processes and requirements and paperwork and ... NEWSFLASH: NOBODY CARES. We are a startup. Many of the MVPs are actually remote. They may not be wearing pants on any given day; I'm not sure. One of the reasons I was hired was to add maturity/realworld regulatory-compliant experience to the company. I have about 7 people in the USA reporting to me, and a few more than that in different countries. Average age of my team is probably mid 20s, but it ranges from "just turned 21" to "early 50s". I need all of those people, for different reasons. Be excellent. That's why they're going to hire you.

There is so much wrong in this I barely know where to begin. Nobody records analog streams for digital TV data, but this is completely irrelevant. Everybody records analog streams for spacecraft telemetry because you can't post-analyze an improperly demodulated digital data recording. Doppler velocity measurement is also performed from the raw signal, for example by mixing with a signal at the original (TXCO-controlled) carrier frequency and observing the beat. The A/D stage is NOT demodulation, it's digitization. A digitized recording of an analog waveform is nothing even remotely akin to recording the binary output of a demodulator stage. (For practical purposes, a modern recording would, indeed, be digital - but it would be a digital recording of the original received waveform, not simply a recording of the realtime output from a demod). Having the original waveform to look at allows different types of filters to be tried and applied, not just the single set of parameters that were in the realtime decoder on board the aircraft. It's absolutely the baseline for data recovery in this type of application. Telemetry = "remote measurement", a term used to refer to data streams downlinked from the vehicle that are not crew communications or control data, which includes still and moving image data.

Comment They're not going to get better results... (Score 4, Interesting) 110

... until they post an analog recording of the telemetry. The bitstream *as decoded* is corrupted because of demodulation errors, and you can't reconstruct data that isn't there. If they have an analog recording, then analog filters can be applied to that in an attempt to create a cleaner input signal to the demodulator stage. An analogy: They have taken a picture of a page of text, rather out of focus and dark, and used OCR software on it. All they are giving us is the output of the OCR software. We need to see the original picture so we can apply better filtering/contrast adjustments to it before attempting pattern recognition.

Those won't work, there are acceptance standards for those photographs. No headgear (possible religious exemption), no tinted eyeglasses, etc etc. Also, how many women do you know with a full mustache and knee-length beard? (I realize the answer to this may be nonzero, but it's going to be small). When I went to renew my passport a few years ago [Australian], they had additional requirements "neutral expression, no smiling" and they were explicit about the fact that this was to improve facial recognition DB matching. All this is nothing at all compared to the databases in the United Peoples' Democratic Republic of Europistan, of course. Interestingly, all this facial recognition and cross-referencing is a real problem for spies. Passports with biometric information in them that can be cross-referenced to a central database are a serious problem to a guy whose job is to enter Russia as Mr. John Smith, tourist today and enter it again next week as Mr. Alphonse Gambolputty, international financier.

fark.com is the one that comes immediately to mind. Of course, I then simply need to block the begging as well. Actually I find adblock indispensable not simply for removing ads, but for removing not-exactly-advertising meaningless UI elements that occupy screen real estate. I'm talking about boxes full of 35 different "share this page on these social media sites" icons, and static headers with flyout menus that stick to the top of the browser window, not to mention those goddamn annoying "toasters" that pop up in the lower right corner once you scroll past a certain spot in an article. And reader comment engines like Disqus, not to mention "recommended related content" IFRAMEs (e.g. Outbrain) on news sites. My Internet experience is completely different from that which would be experienced by someone without adblock, it's a lot more than just the absence of ads.

Comment Re:Insurance Premiums (Score 1) 157

Yeah, this was one of my concerns too - but it would appear with Obamacare no longer allowing charges for preexisting conditions, an increased insurance premium because of DNA screening results isn't CURRENTLY possible. In general, my philosophy is that it should be possible for people to opt out of ALL data collection. Not merely disclosure, but collection. An infinitely large database of information has an infinitely large possibility of abuse. It should be possible for people to opt out of electronic health records, also - or at least have a user controlled kill switch to permanently erase their EHR.

Comment In a word: Yes [I can relate] (Score 2) 263

I worked for about eight years for a Fortune 500 (actually its ranking was two digits... and it wasn't #99). Benefits were great, pay was very good since they let me relocate from NYC (cripplingly high taxes) to FL (no state or city taxes) and keep my NYC salary and bonus. Flipside, I'd already had to change career paths entirely within the organization (from engineering to product management) in order to get a promotion, because the peristalsis was just too slow. And on every side, beset by "you can't get there from here" processes and conflicting goals. The analogy I used was that the company was trying to use a standard process built around the nuclear weapons industry in order to make toy dolls, and wondering why it could never get a project finished in time to be relevant. The only turnover to speak of was people who came in, tried to get things done, and were either torpedoed by vested interests, or gave up the struggle and moved on to other pastures where they could satisfy their thirst for meaningful achievement. About a year ago, I happened across a job posting for a small software company close to my new home in FL. Much smaller, but *DOING THINGS* and generally accelerating upwards. I negotiated the same salary, but no bonus, no 401k match, and generally smaller benefits all round. So I took a "pay" cut of perhaps $20-25k, all things considered, but I do not regret the move for one microsecond; I've already had one promotion, of a sort, and I enjoy what I do (when I'm not cursing at it - hey, this is software, after all! :)). Other people in my position might have felt differently - especially those closer to retirement and looking to stick with a dead-end railroad job to harvest benefits. I'm not young, but I'm also not anywhere near an age where retirement will be possible. And a considerable amount of my personal happiness is tied up in the question "what useful thing did I get done today?" TL;DR: this is a personal decision and you have to decide how much risk you're willing to stomach. And yes there is the possibility you'll be screwed, either maliciously or simply because your employer had expectations beyond what any one person can achieve. All of us on the other side of the internets can't make the judgement call for you as to whether this is a possible malice situation - you've spoken to this new employer, we haven't - and as for the expectations-too-high part, the way to manage this is with explicit goals, preferably chopped up into slices no bigger than three months. Check in frequently to make sure management knows how you're progressing and what things are slowing you down.

Comment This is an old idea (Score 5, Interesting) 368

Turbulent obturation rings of this kind (well, technically I guess these are obturation cannelures) have been used in a lot of applications because they have some interesting properties. For instance they are used in mortar shells. When you drop the shell down the mortar barrel, you essentially want it to fall without retardation so the primer gets a good hard strike and the propellant ignites 100% of the time. However you want as much as possible of the propellant gas to do the job of propelling the projectile, without blowing past it in the barrel. You ALSO want it to be as consistent as possible so the CEP of where the projectile lands relative to the target is as small as possible. So this isn't impossible, but it's not easy either.

Comment This is a meaningless PR gesture (Score 1) 293

The real issue here isn't what specific thing NSA is or is not doing at a given moment. The issue is that they have been seen to act outside the law, which means all bets are off. There is no reason whatsoever, and will never be any reason, to believe any assurances that they might give in the future that "we've stopped doing X,Y,Z". If the NSA was a person, we'd fire him/her, probably fine and jail him/her, and revoke his/her security clearance and make it impossible for him/her to work in any position of trust ever again. You can't do that with a black-budget government agency, especially not one that has voluminous warehouses full of secret dirt on every US politican, lobbyist and billionaire, past and present. There is no way of ripping them out and replacing them, so you need to defang them. Plus, the NSA is not the only such lawless entity with the technical capability to intercept transmissions. Thus, if these big companies want to form an alliance "against the NSA", what they actually need to do is ally on developing privacy technologies that are impossible to subvert, and spending money on public education so the average man in the street knows better how to practice data hygiene. It has been demonstrated that the NSA regards the law as a set of guidelines about what to reveal in PR documents. You can't retreat from that point - there is no way to trust them ever again. Since we can't cure the disease, we need to manage the symptoms. What these companies have actually done is merely to take a public press position (the phrasing of which was likely developed in conjunction with members of the US government), designed to communicate to Joe Public that these various people with a stake in cloud-based computing are Deeply Enraged(tm) about the NSA. And everything will be fixed with a change.org petition and some legislation that will be obsolete by the time it's passed, and ignored by the NSA when inconvenient anyway. The goal is protecting business models, not protecting data.

You can make this argument all day long, and while it seems to make sense, it doesn't address the reality that the percentage of people who buy and wear wristwatches is falling (here's a fun article http://www.bbb.org/blog/2012/05/has-your-cell-phone-killed-your-watch/ ). I'll buy the argument that wearable computing devices simply have never been implemented well, but until you show me the killer implementation of the killer app, I'll continue to assert that the idea of pervasive wearables is a marketing wet dream, not an imminent reality. Perhaps the answer is that I don't CARE what time it is when I go swimming? BTW, just speaking for myself, when I go to the beach - which is all the time, because I live in central Florida - I take my cellphone in a ziploc bag. I even take it in the ocean briefly, so I can take cool pictures. If I have a containment failure and the phone dies, oh well... time for a new phone. I do own a couple of analog wristwatches, somewhere... they're showpieces I never wear. I also don't want a tan line on my wrist.
