dunmalg··on New York Police Officers to Begin Wearing Body Cameras in Pilot Program
Not to mention the fact that the perceived lack of action in one particular case does not accurately predict what happens when it turns into hundreds of cases.
dunmalg··on Weird pricing of Dropbox Pro
> It would be impossible to show the prices with sales tax when there are 50 different states with differing sales tax laws

Heck, the state level sales tax rates are even the easy part. Within states there are counties which often levy additional sales tax, and then cities within the counties do it as well. These county and municipal tax rates are additionally often comprised of a variety of "temporary assessments" which appear and expire seemingly at random. Knowing which rate is charged at a given location devolves into a very difficult problem once you realize there's no centralized address-to-jurisdiction database, nor a centralized jurisdiction-to-tax-rate database.

dunmalg··on This is why you never end up hiring good developers
>Since this interviewer seems to have made up their mind already with pre-conceptions of which candidate is worth hiring, what is the "correct" answer to this question? "Pick random co-ordinates, check, and retry?"

The most efficient way (which is arguably unnecessary for Minesweeper) is to treat a 10x10 play field as a 1 dimensional array of size 100, stick your X number of mines in the first X cells in the array, then use something like the Fisher-Yates shuffle* on the array.

* Y = random number 1-100. Swap contents of cell Y and cell 100. Y = random number 1-99, swap contents of cell Y and cell 99. Repeat for entire array.

dunmalg··on US cable giants calls on FCC to block cities' expansion of high-speed internet
Yeah, there's no contention AT ALL up to the DSLAM. DSLAM is DSL Access Module. Every DSL customer has their own dedicated copper pair from the DSLAM to their house--- it's their phone line. There may be congestion between the Central Office where the DSLAM lives and the rest of the internet, but in practice that rarely happens. The big limit on DSL is getting reasonable speeds a mile down the line over ancient copper pairs that were never intended for the purpose. Don't people remember the old Cable vs. DSL commercials, where the DSL companies were showing cable customers furiously calling each other bandwidth hogs and telling them "log off!"
dunmalg··on I Went from Grad School to Prison
>Is there any possible reform for the disaster that is the plea system?

Prohibit prosecutors from going to trial with charges any higher than they offered in the plea deal. If they offer to (say) let you plead to only misdemeanor drug possession, then they shouldn't be allowed to then prosecute for felony drug possession, resisting arrest, plus anything else they can think of simply because you dared to ask for a jury trial. Sentencing can still be somewhat variable, which would offer an actual incentive to those that know they're caught-holding-the-bag guilty, but would not be such a ruinously life destroying difference that it would frighten the innocent into taking the pllea when they did nothing wrong. The argument against plea bargain reform from prosecutors is always along the lines of "the courts could never handle all those cases, so we have to discourage jury trials as best we can", and frankly, that line of reasoning is bullshit. If there aren't enough resources to offer a jury trial to every offender, then I say we have a crisis of constitutional proportions, and dealing with it by gaming the system to force people to forego their rights simply to improve efficiency is a far more evil thing than most of the crimes people plead to.

dunmalg··on Ozone-Depleting Compound Persists, NASA Research Shows
Multinational businesses aren't that simple. The Bhopal plant was owned by the Indian subsidiary of Union Carbide, UCIL, which was half owned by Union Carbide, and half owned by the Indian government. Among the eight convicted in India in the disaster was the CEO of UCIL, Keshub Mahindra. Indifference to safety by corporations is a global issue. It's not reasonable to pretend Bhopal was caused solely by evil decisions emanating from Texas while innocent foreigners look on helplessly.
dunmalg··on Researchers find it’s easy to hack traffic lights
>Not foresight. It was a limitation of the hardware at the time.

Nonsense. Even mechanically timed lights can be wired to illuminate any arbitrary set of lamp in either direction. The only difference between then and now is that back then you had to physically move wires, whereas now it's software switched.

dunmalg··on A Mother’s Journey Through the Unnerving Universe of ‘Unboxing’ Videos
Heh. Seriously though, it does feel like I have anti-ASMR. I swear, every single thing that is supposedly happy-making for ASMR folks is "please pull my teeth out with pliers" level bad to me. It's like the same neurological response, only wired to my revulsion center. Perversely though, I kind of enjoy the sensation of scratching a chalkboard with my fingernails.
dunmalg··on A Mother’s Journey Through the Unnerving Universe of ‘Unboxing’ Videos
>I tried to listen to some ASMR triggers, and I got the same physical reaction and feelings of discomfort I get from fingernails scratching on a blackboard or hearing someone clean their teeth.

Glad to hear I'm not alone. My wife and I listened to the This American Life program on ASMR and I couldn't even stand the few short snippets in the program. The whispery sound of quiet talking where you can hear the speaker's tongue flapping around in their mouth makes me want to pull my teeth out with pliers.

dunmalg··on An amateur linguist loses control of the language he invented (2012)
>people without linguistics training seem to find it useful for discovering nuances in their own languages that they hadn't considered.

Learning any foreign language will tend to do that, though. It's a function of being forced to consider your native tongue as a language, rather than just speaking it. Plus if you learn a foreign language, you will have the advantage of being able to talk to an established base of people who speak it.

dunmalg··on How To Validate Your Business Idea By Testing A Hypothesis
>"There are no rules for good photographs, there are just good photographs". I disagree with this and think that it is a self-defeating, irrational attitude.

Yeah, I think he's misinterpreting what his photographer friend means. There are TONS of rules for good photographs, everything from technical ("sufficient lighting") all the way up to art theory ("rule of thirds"). The guy's point was probably that any subject, at any time, can possibly be photographed in a way the conforms to the requirements of an artistically pleasing image. Trying to fit that notion to the idea that entrepreneurs should just leap for the stars without checking to see if their figurative lens cap is off is not really very sound.

dunmalg··on Amateur Radio Universal Text Messaging/Contact Initiative
>How did Chris Paget's IMSI catcher demo at Defcon a few years ago work then?

Oh, it's actually not too difficult to modify transceivers to work outside their regional prescribed bands. There are usually internal jumpers or, more recently, firmware modifications to expand their tuning ranges to include bands normally only allowed in other regions. Some of the software defined radios are surprisingly malleable. I was actually mostly just thinking about the possibility of getting a GSM phone to hit an amateur band freq or vice-versa without a lot of hacking.

dunmalg··on Amateur Radio Universal Text Messaging/Contact Initiative
GSM-450 is pretty much right there at the top end of the 70cm, and GSM-950 is right in the middle of 33cm, but here in the US at least the FCC is pretty nuts about insisting that stuff sold here is locked out of other devices' yards. They'd flip out if you tried to import an HT that could hit GSM freqs.

dunmalg··on Just press go: designing a self-driving vehicle
Touch-screen interfaces are inherently imprecise. Ever tried to select a destination on a GPS map?
dunmalg··on How Being a Doctor Became the Most Miserable Profession
Cost of employing someone is more than just their hourly rate * hours worked. For example, at one job where I was paid $26/hr, my time was billed at $48/hr--- and this was for a government agency internally billing itself, so there was no profit margin involved, just the cumulative cost of wages, benefits, and associated overhead.
dunmalg··on Google to Acquire Nest
High end commercial/industrial HVAC systems already have automation that far outperforms anything Nest offers. Google up "honeywell comfortpoint".
dunmalg··on Why a medieval peasant got more vacation time than you
>One Bushman, when asked why he hadn't emulated neighboring tribes by adopting agriculture, replied, "Why should we, when there are so many mongongo nuts in the world?"

This sentence illustrates one of my main gripes with JD's "sunshine and happiness" view of hunter-gatherer societies. Hunter-gatherer lifestyle is fantastic for that small fraction of folks who live where there are plenty of mongongo nuts (so to speak). He sort of handwaves the majority, who are eking a bare subsistence out of the land, or worse, alternately subsisting and starving.

dunmalg··on Bitcoin falls from $266
more like 0.2% of its actual COST. His point is that he thinks cost and value are out of sync.
dunmalg··on Peter Thiel Talks About the Day Mark Zuckerberg Turned Down Yahoo's $1 Billion
I don't know that it's "raw conviction". That's the sort of thing a tech-ignorant CEO needs. Sounds to me like Zuck simply isn't the sort of guy who is interested in being rich at the expense of not having something interesting to do. Like most programmers, he was probably having the time of his life playing around with a huge interesting programming project.
dunmalg··on Why Clarence Thomas Uses Simple Words in His Opinions
>"Hand-wavey" is not a term that ever comes to mind reading Scalia's opinions (except when talking about drugs or gays).

I'd say his opinions become "tortured" when he is forced to address issues that he and the US constitution are at odds over. He practically refuses to admit the 14th Amd even exists. Have you read his views on the 9th Amd? He thinks it only protects the right of the states to recognize some sort of second-class "lesser" rights. His opinions may be thoroughly reasoned, but by god they're certainly not always rational.

dunmalg··on Multitasking makes you dumb
"and running over motorcyclists ("I just didn't see him there!")"

I'd call you sexist, but my sample size of one smashed femur by a female left turner who didn't see me fails to disprove your theory.

dunmalg··on Multitasking makes you dumb
"And BTW, you should probably never fly in an airplane if you believe this BS since pilots constantly listen and talk on the radio while flying planes and navigating in the same time."

To be fair, airplanes are not comparable to automobiles. Flying an airplane does not actually require nearly the amount of attention driving a car does. The sky is mostly empty, and planes will generally continue to fly straight ahead even if you let go of the control yoke. If you look away from the sky while flying, you're highly unlikely to swerve out of your air lane into another plane, rear-end a plane in front of you that braked suddenly, T-bone another plane at an intersection, or fly into a pedestrian using a crosswalk.

dunmalg··on Rob Pike: The Best Programming Advice I Ever Got.
It's sad to say, but the majority of people cannot follow a logical progression more than a two or three steps. It's not even an issue of "smart" vs "dumb", as many of my quite clever coworkers have this issue. It seems to me to be predicated on the ability to keep a lot of state in your head. If in order to reach an answer you need to synthesize the results of two logical conclusions and you can't keep the first result in your head while you work on the second, you're going to get lost.
dunmalg··on Hacking and defeating Google's reCAPTCHA with a 99% accuracy
How about when I say I hate videos of what should be written text because years of exposure to gunfire in the Army has impaired my hearing?

I will never understand why people think that the crappy audio channel of a youtube video of some guy "umming" and gulping through a poorly prepared speech, all recorded on a $5 microphone, is a suitable way of passing information.

"it gets cognitively tiring to sort people appropriately into one-and-only-one circle."

That's not how it works. You can put people into as many circles as you like.

dunmalg··on TrueCrypt User Held in Contempt of Court
I'm partial to "I kept this week's password on a post-it note stuck to the keyboard. Did you lose the post-it?"
dunmalg··on TrueCrypt User Held in Contempt of Court
"I changed the password every 3 days and never memorized it. Current password was on a post-it on my monitor. Did you guys lose the post-it?"

Simple as that, right? They can't compel you to remember information you never had in memory. It's probably too late, as he's likely admitted to remembering the password. Dumb move.

dunmalg··on A Localization Horror Story: It Could Happen To You
For the most part, it would work in essentially ANY language. The "noun, colon, number" notation completely sidesteps the issue of grammar by dumping the verb, which is usually the instigator of the worst problems (Russian, I am looking at you!). For example, the easy way out in Russian is simply "каталоги: 5", which is the nice and easy plural "directories", free from abusive endings imposed by accusative case verbs.
