DArcMattr··on Video Games That Made People Question Their Beliefs
The article's first example is of a person using a metaphor common to the ex-Mormon community about breaking "the shelf". "The shelf" is where the facts that bring one to question church doctrine go to be explained (or not) later.
DArcMattr··on France’s Message for Capitalism: Adapt or Die
Economically, the fairest tax system is one that does not affect people's behavior. The most straightforward means of doing this is a head tax, but that's not politically feasible. The best thing to do is a sales tax on price inelastic things.
DArcMattr··on Ask HN: Why did you quit your last job?
I was assigned a new manager, and they curbed a lot of the unofficial perks I'd been enjoying, like being able to work from home some days.

When it came time to turn in self-evaluations, I turned in a quitting notice. I couldn't bring myself to work through that self-evaluation.

DArcMattr··on Are real numbers really real?
Keep in mind, this is using terminology that comes from courses appropriate for advanced undergrad/beginning graduate level math courses.
DArcMattr··on Cloudflare Might Be Exploring a Way to Slow Down Ajit Pai's Home Internet Speed
How petty of them.
DArcMattr··on The Curse of Econ 101
I have a Master's in Economics. In graduate classes, much of the work done in intro-level courses is tossed aside for more capable models that require a fair bit of calculus to understand. The easiest being the Solow growth model.

The intro courses delve into macro static models with at most 2 variables (think Keynsian Cross). In the graduate level, macro theory is taught as micro theory. While the deleterious effects of price controls still hold true at higher levels of economic reasoning, it's a multi-variate problem. With any price control, think of it as damage the rest of the people acting in the economy think of ways to route around. If a minimum wage increase takes place, perks can be cut without affecting overall employment levels as an example of how overall employment may stay the same.

DArcMattr··on Malicous code written into DNA infects the computer that reads it
This is almost the plot of a scifi novel published in 1994, The Deus Machine, by Pierre Ouellette. The malicious code was placed in introns by nature itself.

Need to sanitize those inputs!

DArcMattr··on The new age of Ayn Rand
If only this were true.

I worked at the Ayn Rand Institute, and still keep tabs with their activities and their progress.

If Ayn Rand's ideas were as widespreadly acknowledged and held, then we'd see a distortion free economy, not a series of spin jobs all geared towards acquiring political power.

DArcMattr··on Nvidia's “Open-Source Guy” Has Left the Company
At the very least, vendors should provide something like a data sheet with all the register information a developer would need to write their own driver. There's no need to give away the recipe to the special sauce.
DArcMattr··on Openbsd router, can it run on arm?
The ARM SoC marketplace's common hardware denominator is the CPU. The rest of that system differs widely between vendors, and documentation for the pieces is poor-to-nonexistent.

Two OpenBSD devs run the Garbage.fm podcast [1], and they often lament about this state of ARM hardware.

DArcMattr··on When Job Titles Offend
The certification comes through acquiring and maintaining the Professional Engineer credential: http://www.nspe.org/resources/licensure/what-pe
DArcMattr··on Free will is dead lets bury it
The Aristotelian treatment of causality is what's needed here. Objects act in accordance to their nature. Cause and effect is the course of how objects interact with each other. For a given situation, objects A & B will produce the same results if made to interact with each other in a given way.

This is in contrast to the Humean treatment of causality, which is a listing of events where objects play a nominal role.

Let's consider the case of a person considering an argument for determinism. The arguer is presenting a logical sequence of statements building to a conclusion. The considerer is having to focus on each of the presented facts and how they relate to the conclusion. It is this act of focusing which is the core role of volition. The arguer is counting on the focusing act to take place in order to present an argument for determinism. It may be argued that volition can't be proven, but in order to argue against it, it's necessary to rely on volition still the same. Funny thing, volition.

DArcMattr··on Undercover Activists Buy Off Professors in Climate Sting
You mean using a taxicab metric to construct a circle? Been done.
DArcMattr··on Exxon Mobil Investigated for Possible Climate Change Lies by NY Attorney General
Even if somehow tomorrow, all the cars on the road switch to a power source that had nothing to do with petroleum, we would still need loads of oil. Petroleum is a raw material input for many necessary products in our day-to-day lives: plastics, textile fibers, lubricants, medicines, asphalt.
DArcMattr··on Math professor forced to use $180 textbook written by his boss
The article said he used two books, one of which was free. Ordinary Differential Equations make use of linear algebra concepts, but can be self-contained.

It's entirely plausible to go with Strang, and another book for this type of course.

DArcMattr··on Beware “mathiness”: Algebra and data to reinforce ideological preconceptions
Kay was referencing an idea originated by Stigler, the Inventor, to use as a contrast to Feynman's stance. There was no attack on Stigler as such.
DArcMattr··on Rough idling
And here's some discussion on making OpenBSD's sleep more efficient (starting with a proposed patch from tedu): http://marc.info/?l=openbsd-tech&m=144280057027331&w=2
DArcMattr··on An Introduction to Taxicab Geometry
Shull doesn't mention the book by Krause [1], which provides exercises for the reader to develop an understanding of Taxicab Geometry.

DArcMattr··on A native hypervisor is coming to OpenBSD
Theo is objecting to the view that VMs are a security necessity.
DArcMattr··on Stop using tail -f (mostly)
I'm still going to use tail -f, in tmux. I get the log stream, and I get tmux's search & movement.
DArcMattr··on Towards axiomatic morality
After a brief skimming on my lunch break: The approach this author takes is similar to the one that Baruch Spinoza uses in formulating a system of ethics, and which David Hume tears apart. His works cited don't reference anything written before the 20th Century, so it looks like the author hasn't done the homework.

The "book" is hard to navigate, this is the whole book's table of contents: http://dematerialism.net/POS.html

DArcMattr··on Roundup and Risk Assessment
It's proving a negative assertion, which is impossible. The burden of proof is on the person making positive claims.
DArcMattr··on Composer – Disable GC when computing deps and refs
If the Pull Request has to do with a bit of UI/UX, images and animations are appropriate, to demonstrate user interaction with the interface.
DArcMattr··on LibreSSL: More Than 30 Days Later
Then there's also this: http://www.openbsd.org/cgi-bin/man.cgi/OpenBSD-current/man1/...
DArcMattr··on What's a Mathematician to do?
Sadly this seems to be the state of the higher level discussions on the various Stack Overflow sites that get shared through Y Combinator. Fundamental questions are closed off because they're out of scope of the site they're asked on.
DArcMattr··on LibreSSL on Gentoo
The current source for OpenSSH no longer requires linking to (Open|Libre)SSL http://undeadly.org/cgi?action=article&sid=20140430045723
DArcMattr··on Ask HN: Best current Linux-compatible laptop?
The Haswell refresh has been full of laptops where corners have been cut in the form of lower production quality, many convenient features being removed, and questionable keyboard layouts. There have even been a couple of ThinkPad-branded keyboards that do not have trackpoints.

I realize that in order to make a lightweight and power-efficient laptop, there have to be tradeoffs, but the ThinkPad has historically been a premium brand, where frills like indicator lights, hardier materials and more generous keyboard and trackpoint/trackpad button layouts are expected. Their absence in the Haswell lineup is saddening, yet Lenovo still "wins" by default because all the other companies' offerings are even more deficient.

DArcMattr··on Web SQL Database: In Memoriam
WebSQL yet another web spec that the Mozilla Foundation won't implement because of "problems". There are a few bits of CSS that I would love to use all over the web, like "display: run-in", but Gecko is the only holdout.
DArcMattr··on Guess Who Makes More Than Bankers: Their Regulators
The FED is in a regulatory gray area where it is, yet is not, a government department.
DArcMattr··on Apple SSL/TLS bug is possibly a deliberate job
And this is why I can't understand why people don't use matching braces in my control structures. Not using them is asking for this kind of error.
