shpxnvz··on Rand Paul wants to lead a Supreme Court challenge to Feds' tracking of Americans
While this is undoubtedly true for some senators, Paul seems like quite a poor choice of target for this criticism.

He has been very vocal in opposition of governmental encroachment on civil liberties during his senate term. He was, in fact, the last senator left in opposition to the extension of the Patriot Act.

shpxnvz··on All the Startup Advice You Read is Wrong
"There is no such thing as luck; there is only adequate or inadequate preparation to cope with a statistical universe."

Heinlein captured the essence succinctly. Luck is nothing more than a label people use to describe probabilities they have not planned for.

shpxnvz··on Come here and work on hard problems – except the ones on our doorstep
Because Obamacare is funded by progressive taxation, as are most programs in the U.S., and the benefits of Obamacare are not equally distributed - an example of the very inequality Hayek was admonishing against in the first quote I posted.
shpxnvz··on Come here and work on hard problems – except the ones on our doorstep
"Obamacare" is not socialist, it's liberal, as a core concept of liberalism is that the state should fund things that people cannot or will not fund for themselves, like roads and healthcare.

"More doubtfully compatible with the liberal conception of equality is another measure which also gained wide support in liberal circles, namely the use of progressive taxation as a means to effect a redistribution of income in favour of the poorer classes. Since no criterion can be found by which such progression can be made to correspond to a rule which may be said to be the same for all, or which would limit the degree of extra burden on the more wealthy, it would seem that a generally progressive taxation is in conflict with the principle of equality before the law and it was in general so regarded by liberals in the nineteenth century."

shpxnvz··on Pirate Bay Takes Over Distribution of Censored 3D Printable Gun
It's worth noting that with a basic milling machine (about $400) an individual in the U.S. can legally manufacture for personal use an AR-15 lower receiver from either a bare or partially machined forging ($50) in as little as a few hours. Some have done the job with only a Dremel or hand drill, making the investment much cheaper.

I share this only to illustrate that this technology is not enabling a radical new ability to produce cheap personal-use weapons, but more of an (expensive) prototype evolutionary step in the process.

In addition, possibly in contrast to this printed design, a home made receiver that is properly surface-hardened after machining is fully as capable and safe as any other receiver manufactured to the TDP.

shpxnvz··on Dear Apple, let's talk about photos
English can be really inconsistent at times: "lose" and "loose" are pronounced exactly the same yet have different meanings.

Not to be pedantic, but they are not pronounced the same in American English.

shpxnvz··on When empathy becomes insulting
> many of them so tightly constrain what the people say, you might as well be talking to robots

I worked for a company (they were the U.S. market leader in their online communications niche) who took this to an extreme. They outsourced their customer service, and in a misguided effort at quality control scripted every single response a service rep was allowed to say. As in, they were literally prohibited from saying anything that was not a scripted response during a support call.

Eventually a rumor circulated that the folks responsible for retention and turnover decided to fight their poor numbers by manipulating the scripts to make it as difficult as possible to cancel service. Don't know for sure if that was true, but there was circumstantial evidence in the (sometimes comical) live chat scripts that infuriated customers posted online.

shpxnvz··on What's Tylenol Doing to Our Minds?
So, the incidence rate for accidental overdose is something like .048 per hundred thousand persons, compared to murder which is 4.7 per hundred thousand persons. You are 100 times more likely to be murdered than accidentally overdose on Tylenol. I'm not sure why there is so much concern over this?
shpxnvz··on What's Tylenol Doing to Our Minds?
> you can buy paracetamol in packs of 200? jeez. isn't this one of the main killers, though overdoses (many accidental)?

Do you (or anyone else) have some concrete data for incidence rate of fatal overdoses in the U.S.? I'm curious if it's really all that common.

shpxnvz··on Shots fired at MIT - report of an active shooter near Bldg. 32 (Stata)
Boston has about 60 murders per year. 56% of murders in Massachusetts involve a firearm. Therefore, Boston sees about three murders involving a firearm per month on average.

This does not, of course, include justifiable homicides.

ETA: So as not to scare anyone remember that in major cities typically between 65% and 91% of murder victims are criminals, and most of the killings are gang related.

shpxnvz··on Show HN: God mode in production code – a new way to debug in Scala
Given the nature of JVM agents, this means that the Tikipi backend, should it choose, may access all the data in the production application. Correct?

ETA - Thanks, missed that page on the site.

shpxnvz··on Show HN: God mode in production code – a new way to debug in Scala
Signup is broken right now, so maybe someone else can answer. From the website it appears that the debugger is a SaaS app that connects to the agent on your production box from their servers... is this the case?
shpxnvz··on MtRed Bitcoin mining pool will be shutting down
When I lived in Santa Barbara we had a gas furnace. I'm surprised that, given the cost of electricity out there and the moderate temperatures which are nearly ideal for heat pump efficiency, that the financial incentive isn't there to convert even for moderate use.

But, thanks for clarifying.

shpxnvz··on The Importance of Overdelivery - experience using FlightCar (YC W13)

Does your home have a heat pump? If so, your house heat pump is 3 to 4 times more efficient than the waste heat produced by your computer, and you are using 3 to 4 times more electricity compared to the same heat output from a heat pump.
shpxnvz··on Bullseye from 1,000 yards: Shooting the $17,000 Linux-powered rifle
I understand, and it's a good point. That statement was just a personal lament based on my observations of the community of 2nd amendment supporters over the last few years.

I am in Maryland, Carroll County specifically. I'm a member of MSI, SAF and the NRA and have been engaging as much as possible with our senators and delegates over the last few weeks.

I'll likely be retreating to Pennsylvania or Virginia in the next couple of years - I'm sure many others will be as well. In the meantime, keep your powder dry and perhaps we'll meet one day on the range. :)

shpxnvz··on Bullseye from 1,000 yards: Shooting the $17,000 Linux-powered rifle
To be clear, I was not referring to you in any way. I was just positing why the above poster may have concluded that those who speak out in support of the 2nd amendment are marching to the parchment.

Maybe it's polarizing, but there really are only two sides in this fight. There's no middle ground here - there is the ideal of freedom or there is "compromise". Not a compromise in the proper sense of the word, though. It is a pure loss, for you have less freedom than you started with and nothing in return. Votes cost nothing, so this compromise can be (and is) demanded over and over again. The end result is what we face in Maryland, never-ending iterations of legislation with no rational link to the real world, and thousands (like myself) who dream of moving to a state that is slightly more free.

> The problem with hand loading is that you just have inconsistent results...

That's a pretty ridiculous statement for them to make. A person who drops $17K on a precision rifle (and you can drop a heck of a lot more than that on a quality rifle without all the electronic crap) damn well knows about consistency in ammunition, and most of them are going to be experienced handloaders as well.

The best shooters in the world handload, and that includes the U.S. Army Marksmanship Unit (who can certainly afford the most expensive factory ammo). They do so because you simply can't mass produce cartridges that are as accurate and consistent as handloads. You can't mass produce ammo tailored to the chamber tolerances of a specific rifle. You can't fire form enough brass at the factory to load a lifetime's worth of ammo for an individual rifle. Even if you tried, you're back to square one after you replace the barrel at 5K rounds.

As a result, you end up paying $17K for a rifle that cannot possibly be used to it's fullest potential.

> From the quote above, I doubt the software can compensate for different grain bullets or different amounts of powder.

This could be, but if so would destroy the premise that this computerized gizmo offers any improvement over a human calculator. Experienced shooters have no problem memorizing ballistics tables for their particular loads - that this computer could not would be, well, laughable.

I apologize if I'm being grumpy about all this. It's simply depressing to me that with all the challenges, intricacies and fascinating phenomena in the world of shooting folks here are so fixated on the little computer they strapped on top.

> I don't understand the point of this rifle. Is it to enable non-shooters to shoot? It's not hard to learn how to shoot. With an afternoon of instruction and a few practice sessions, you can hit 1000 yd targets with a normal scoped precision rifle without much difficulty.

I gather that it must be more publicity stunt than anything; or perhaps at best a vehicle to a lucrative government R&D contract. Shooters don't need or want this and those who don't shoot because they think it's too hard won't pay for it (if such a person exists at all). The government has no possible use for it beyond automated weapons systems which they already operate, but I wouldn't put it past them to pay for additional development just for the hell of it.

> I think for myself. You get your marching orders from some parchment. It's people like me who made this country. It's people like you who bowed to King George.

I won't speak for bmelton but it's disingenuous to label second amendment supporters as folks who "get [their] marching orders from some parchment". Most I know recognize the right to self-defense as merely being guaranteed by the constitution rather than granted by it. The confusion I suspect is from the "parchment" often being used as a convenient argument - many in this country take for granted uniform agreement that the document does in fact bind the government; ergo to them the argument is trivially won by quoting it.

They do not always realize that those they argue against view the constitution as a "living" document subject to interpretation, and may summarily discard arguments that appeal to it's guarantees. It is also damaging to their argument that so many are willing to to support the government's disregard of the 1st, 4th, 5th, 6th, 9th and 10th amendments while fervently supporting the 2nd.

> We all draw a line where we think something is too dangerous to be legal.

No, not everyone does. There are quite a few of us who conclude, as many of the Founders and their contemporaries did, that the government has no ethical authority to judge what the people are worthy of possessing, and more to the point, has absolutely no ability to do so without devolving into oppression.

There are regrettably far fewer of us than those who subscribe to the alternate view, but we do fortunately share rank with a large contingent of the second group who at least draw the line somewhere past firearms.

> ...means that it requires everything, including ammunition, to come from the company who makes the rifle.

This is baffling... what on earth makes the ammunition proprietary? Does the chamber or priming system deviate from the SAAMI/CIP specifications for those cartridges?

shpxnvz··on How Google Sliced Away Our Knife Ads
To be accurate, there are no weapons features that have been banned from private ownership and use in the U.S. at the federal level. Certain weapons fall under regulation of the National Firearms Act and require payment of a tax before transfer. Examples are machine guns, suppressors, destructive devices and short barreled rifles/shotguns. These are all legal to own by individuals at the federal level.

A few states do outlaw or ban some specific NFA weapons however - for instance 5 states outlaw individuals from possesing machine guns.

shpxnvz··on How Google Sliced Away Our Knife Ads
That's not right, or at least not nearly the whole story. Of course use of automatic fire is discouraged for situations where it's not effective, such as engaging point targets with aimed accurate fire. For other tasks, the most obvious being suppression, automatic fire can be very effective. Capability of automatic fire was and always has been a requirement driven by the military. For a recent example, look at the U.S. Army requirements for the individual carbine program - selective fire is a requirement for submitted designs.

Anyways, none of this impacts the fact that the term "assault rifle", as introduced with the German Sturmgewehrs and now subverted by the U.S. media to mean "scary looking gun", has a specific military meaning that distinguishes it from other small arms like the battle rifle. Let's use Wikipedia's definition: An assault rifle is a selective fire ... rifle that uses an intermediate cartridge and a detachable magazine.

The distinguishing features of the assault rifle, compared to the contemporary battle rifles at the time it was popularized (like the M1 Garand), is that it is chambered for a lower powered non-pistol cartridge (which translates into lighter weight), has a detachable magazine and is capable of burst or fully automatic fire.

I'm not aware of any military or paramilitary organization that uses a definition substantially different from this, or anything like the one you've suggested.

shpxnvz··on Nanoparticles loaded with bee venom kill HIV
Hood also sees potential for using nanoparticles with melittin as therapy for existing HIV infections, especially those that are drug-resistant. The nanoparticles could be injected intravenously and, in theory, would be able to clear HIV from the blood stream.
shpxnvz··on The Department of Homeland Security Stole My Boat Today
You're missing the critical aspect of these interactions: one of the persons is an agent of the state acting under the color of law. The victim is not being nice out of courtesy. They are being nice to avoid having force against them escalated. Were it a private citizen offering the same deal - avoidance of coercive force in exchange for pleasantries we'd call it extortion.

I can't blame the lobbyists either, they're just looking out for themselves the same as the rest of us do.

I can blame the legislators. They're the ones with a monopoly on force wielded against us for their own gain.

shpxnvz··on World trembles in confusion and/or fear at Iran's fiberglass airplane
Oh, just look at the pictures! Look at the fiberglass seams on the body and the shoddy finish of the skin and moldings in the cockpit. Look at the edge where the canopy seals. See any structural attachment points for the canopy? Compare to a real airplane [1] and see if you can spot the differences.

shpxnvz··on Thin-Film Solar Power To Be Sold For Less Than Coal Power
> The question is, how much of this deal is government subsidy?

From the original article:

"When you add in the incentives, the PPA value becomes more comparable to rates we’ve seen signed in California," said Kim.

Apparently nearly all of the difference between standard solar rates and this rate is due to government subsidy.
