bonsaitree··on Tynt’s Chief Operating Officer Talks About Privacy
Indeed. Tynt is an absolute abomination going against both basic clipboard usability and Web content mores.

I will forevermore pronounce Tynt as taint.

Additionally, it's nothing "new".

bonsaitree··on London Met Police lab uses "electrical network frequency analysis" (ENF)
"You need a random source close to 60hz" Correct. I specified a Zener diode source coupled to an oscillator.

This would provide the signal noise filtering and phase-locked-loop (e.g. the necessary +- ppm signal power spectral distribution control).

Given propagation losses, my ENF signal doesn't have to be nearly as powerful--merely more closely coupled to the device(s) being "shielded".

Also, I think a so-called fast-switching DC-to-DC converter would provide the necessary isolation. Plenty are being manufactured now that isolate down to 40Hz, but outside of the audiophile realm, that quality of filtering isn't typically used for low-power applications.

bonsaitree··on London Met Police lab uses "electrical network frequency analysis" (ENF)
Seems like a suitable countermeasure would be a localized source of randomized ENF (say a Zener diode in cascade overload in a low-freq oscillator), but the coupling would be sufficiently different as to highlight the deliberate attempt at ENF obfuscation.

As the U.S. has essentially 5 power grids, they would need a more detailed database too. Still, fascinating stuff.

bonsaitree··on The Upcoming Generation of Lossless Data Compression, Part 1
There was some really forward-thinking work on Fractal Image Compression in the late 90s, but largely due to time-efficiency, plummeting storage costs, and patent encumbrances, it's never caught on.
bonsaitree··on You are Not the CEO
FWIW, certain legal documentation mandates the role of an "executive officer" or "president", but clearly those are mere formalities in companies of this size.

I've always preferred to keep titles quite "loose" (e.g. "Member of Technical Staff","Sales","Support", etc.) outside of "Executive Staff" and "Founder" since nomenclature eventually reflects expectations as the enterprise scales.

bonsaitree··on 6pm.com's 1.6 million dollar pricing mistake
Silver lining.

Until today I had not ever heard about 6pm.com.

Due solely to their mistake, this post, and their honor, I'll be sure and check them out for future purchases.

bonsaitree··on Don't Talk to the Cops
Depending on the state and whether or not the inquiry comes from local or federal officials, you MAY be required to give your full legal name and full address of your legal primary residence. That's it.

Ever since the Hiibel ruling http://en.wikipedia.org/wiki/Hiibel_v._Sixth_Judicial_Distri..., the states have adopted a hodgepodge of differing identity query standards.

bonsaitree··on Don't Talk to the Cops
My route standard response to law enforcement queries:

"I'm sorry Mr./Mrs/Sargent/Lt X, but I don't talk to police on material matters without counsel present."

bonsaitree··on Start-ups still don't know the way to San Jose
No surprises here. Nothing serves as a better poster child for that "uncanny valley" just outside Silicon Valley than San Jose.

San Jose is literally the end-of-the-line on Caltran and has no single "cultural" or "business" identity of its own.

In the bay area, the cream (e.g. money) continues to "rise northward". Given a choice, why would anyone choose to live "so close, yet so far" away from the economic or cultural center of activity?

They don't.

They choose either to pay the "Bay Tax" in terms of congestion and fixed living costs to be "in the center" of things, xor reap the significant cost savings, but relative isolation, of living well outside the region (Portland, Boulder, etc.).

bonsaitree··on I am one of the creators of the first "synthetic" bacterial cell. AMA
How much of the work is Hamilton Smith's http://en.wikipedia.org/wiki/Hamilton_O._Smith compared to Mr. Venter's? I know he's not the type, but I'm really surprised that at least his name isn't mentioned more often.
bonsaitree··on Ask HN: What streetsmarts have you learnt?
I think "make everyone look bad" advice only applies in a specific set of job contexts where team members are essentially interchangeable, rewards are largely zero-sum, and there is a higher value placed on throughput and compliance than creativity and innovation.
bonsaitree··on Ask HN: What streetsmarts have you learnt?
So true.

When someone new moved into the neighborhood, my Dad used to always go over and attempt to borrow a simple hand tool.

Keep in mind, (at that point) my father had been a mechanic in the Marines, a butcher and chef for over 20 years, and a serious cabinet-maker for over a decade. He already had every tool he needed.

His purpose was to "ask a favor" to simply start-up a conversation and a relationship. It's amazing what you can establish by simply asking a stranger for "a small favor".

bonsaitree··on Ask HN: What streetsmarts have you learnt?
Overt initial intimidation is usually an attempt to mask a weakness or fundamental flaw (Thanks Dad!).

This lesson has applied equally well to middle-school brawls, sports competitions, college professors, and litigious organizations.

bonsaitree··on Word Fails Me - Why doesn’t Microsoft’s writing tool actually help writers?
Does anyone who writes words (or code) for a living know anyone who would ever consider using such a tool in the first place?!

Please. The best writing tools are a good text editor, a simple meta/mark-up ontology, and a focused mind.

bonsaitree··on Ethics: a company goes back on its promise to pay interview travel expenses?
I can't stress this enough.

DO NOT rely upon emails at this point. The company can simply ignore them and nobody is going to fork over the money for a full discovery search of those server logs.

Think again about how long this has been ongoing. Given the alleged written evidence, any going concern of repute would have long-since paid the amount owed xor provided you with a formal debt instrument, or proof of its inability to pay.

Since you are an individual and not a licensed debt recovery firm in Virginia, use ONLY brief & polite status-checking phone calls and registered return receipt http://tinyurl.com/7wrzm USPS mail (you could also use courier services, but nothing about this matter would seem to necessitate that level of timeliness).

bonsaitree··on Ethics: a company goes back on its promise to pay interview travel expenses?
Um, I HIGHLY recommend that you DO NOT do this.

Technically, you are mis-representing yourself as an "officer of the court" (e.g. a firm which employs people who have passed the Virginia bar). It's a crime similar to impersonating a law enforcement officer.

However, along these lines, it's perfectly reasonable to hire an attorney (some will do it gratis or for an extremely small fee) to draft a follow-up "letter of demand threatening suit" in their office's letterhead.

In practice, all this does is intimidate the legally ignorant (e.g. not normally any kind of corporation) since the attorney must go through the exact same legal hurdles as the debtor and the amounts involved in this case would never be worth engaging the firm's personnel.

Essentially, these levels of disputes are "write-offs" and "costs of doing business" to those who can afford to hire an attorney in the first place.

The only reason to engage an attorney here is if you wished to wage a profitless, but potentially damaging, negative PR campaign (think Gloria Allred) against this firm.

bonsaitree··on Justin.tv Beats YouTube in Time Per Viewer by 2-1 Margin
This article's analysis is dross. This is purely a selection bias issue. ANY significantly smaller video site with similarly-sized content will have a higher engagement metric.

This is no different than "deep" cable television channels, or really, ANY form of niche media down to individual book authors.

FWIW, A.C. Nielsen knows this all too well and says as much in their "cultural impact" reports (Full Disclosure: I once worked on A.C. Nielsen software). A fact which is conveniently missing from this article.

bonsaitree··on Ethics: a company goes back on its promise to pay interview travel expenses?
FWIW, that sort of phone behavior can be construed as "harassment". Additionally, VA is a "one-party" wiretap state so the company could very easily record the content and frequency of these phone calls and have your number blocked, and/or file a criminal complaint against you.

You are correct in that emails can be deleted, logs altered, and records "misplaced".

A single written demand letter (sent registered return receipt) by USPS is all the "notification" necessary.

bonsaitree··on Ethics: a company goes back on its promise to pay interview travel expenses?
The ethics are clearly in your favor, but it's highly unlikely that formal legal actions will result in any net dollar gains on your part. I'll explain.

Assuming you've completely exhausted casual diplomatic channels, I would firstly send out a formal "letter of demand" (registered return receipt) which includes an itemized list of your expenses, copies of your receipts, the relevant correspondence, and "pay-by" date (usually 30 calendar days from post-mark). Think of it as if you're formally presenting your case to a judge, but that judge is pre-disposed to rule against you. Be thorough.

Legally, assuming you have documentation to back-up their $750 budget, their request for your physical presence, and your $700 of expenses, it looks like a clear case of "breach of contract".

The only flimsy legal leg the company might have to stand on is if the particular HR representative didn't have "agency" to represent the company in your travel reimbursement negotiations (highly unlikely since it seems as if you've already spoken directly with someone who's post-facto implied such an agency by haggling).

I live in Northern Virginia just south of Herndon. FWIW, IANAL, but as a business owner, home owner, and investor, I have more than a passing personal expertise in VA commercial contract law at both the small-claims and general district court level.

If, after the formal demand letter, they don't pay-up and you still wish to pursue formal channels, the amount falls under small-claims statutes. Technically, you'll be filing for a "warrant in debt" [PDF] http://tinyurl.com/2fk54ce rather than "breach of contract". This is both good and bad. It's good since the current general case docket in VA right now is about 10 months.

It's bad in that, as a person, you MUST represent yourself in small claims court in VA. Only a company has the "luxury" of formal in-court legal counsel under small claims in VA. At the minimum, you're going to incur a risk that your additional filing and travel expenses to/from the hearing itself may not be included in the final judgment (most of the time they aren't). Nevertheless, you'll want to include them for possible liens, etc. Much like taxes, don't be afraid to itemize. Since it seems that some time has past already, don't forget to include interest.

If the company is not properly registered in VA (check here https://sccefile.scc.virginia.gov/ ) you'll have to file suits against its owners. One other "gotcha" that particularly litigious companies will often try to do is opt for a formal transfer of your case to the normal civil docket. If they're already paying retainers for legal representation, it costs them essentially nothing to try.

Amortize these formal efforts over time. I suspect that your individual attention is worth far more than the resulting hourly rate.

bonsaitree··on DIY Desk Cable Management System
Here, here.

Cable management is essential for a data center where multiple sets of maintenance hands, multiple owners, SLAs, fire codes, and cooling/venting needs demand organized layouts.

Cable management is also important for tight spaces (inside walls) and extremely low-duty-cycle, but mission-critical wiring such as a home's breaker-box.

Is it necessary for the typical modern desktop with a few AC Power, networking, and USB cords?

Um, NO.

bonsaitree··on Caring for Your Introvert (2003)
I love how this article is 7 years old and it keeps getting reposed time & again. Classic stuff.
bonsaitree··on An NBA Superstar with No Stats (2009)
Just one example: http://tinyurl.com/2739npb

It's not that sabermetrics itself is without value, but the principles put forth in MoneyBall for "success" with sabermetrics in baseball have not held water for other teams in other markets.

Even arguing the other side of the coin, it's easy to make the case that with resources like Baseball Prospectus ( http://www.baseballprospectus.com/statistics/sortable/ ) available to all, any small sabermetrics arbitrage advantages which Beane & Co. may have once had are obviated.

bonsaitree··on An NBA Superstar with No Stats (2009)
True. In financial markets, even small inefficiencies and impedance mis-matches can be exploited due to liquidity, fine-granularity, high transaction volumes, and uniform standards of measurement. The same principles don't down-scale to the individual athlete or small-group (team) dynamics.

Put another way, financial market strategies (in theory) can be constructed on matching/measuring against a continuous variance in capital efficiencies. Human performance is simultaneously less consistent, discrete, and difficult to measure.

Put another way, think of matching the torque/horsepower vs. rpm curves for a typical family sedan's engine versus a high-compression race engine. The former can get good performance with an automatic transmission, the later requires a stick shift and an experienced hand on the till.

bonsaitree··on List of Guantanamo Bay detainees accused of possessing Casio watches
It's a kiss-simple, cheap, innocuous (until recently) timing, team coordination, and secondary intelligence gathering mechanism (via time-indexed observation logs of potential target activities).

These models are probably available for cash (at or below cost) through a plethora of street-side vendors, pawn shops, and cheap electronics retailers in any metropolitan area.

In principle, this is no different than "burner" cell phones historically used by drug dealers (and featured prominently in season 3 of The Wire).

I can envision more well-funded groups using Flip cameras.

bonsaitree··on An NBA Superstar with No Stats (2009)
Actually, it is. Mr. Lewis can spin a fine yarn, but as with much of his first major work (Liar's Poker), a good deal of detail, and outright truth, is sacrificed to back-up the original thesis and offer a more compelling reader narrative.

With hindsight, and much more data, long-term trending analysis of the Sabre-metrics examples given in Moneyball have not correlated with increased team, or even individual, performance in baseball.

Basketball is an entirely different kind of animal. The data miner in me looks forward to seeing if this sort of analysis will offer genuinely useful predictive performance models this sport.

bonsaitree··on Flash is a CPU hog?
No. You misunderstood my verbiage. Rather, that Adobe has had more than decade to refine their algorithms and data structures so asking comparable performance from, ahem, far less than a decade's worth of engineering development is rather short-sided.
bonsaitree··on Flash is a CPU hog?
Yes, it is. Any kind of non-hardware-accelerated video playback will be CPU-intensive. The MAIN point is that Flash is MORE CPU-intensive for a given frame-rate, color depth, and resolution than comparable codecs.

Comparing open, fresh-off-the-vine, HTML5 animations to a decade-old proprietary implementation like Flash is also a non-starter.

On the plus side, Flash videos currently make great, handy fan-speed servo tests for any Mac laptop.

Nothing. It was just recently announced that the full-body scanner machines will shortly be mandatory for all U.K. international arrivals.
