agjacobson··on Canada's Toughest Border Crossing
Escape at Dannemora
agjacobson··on French Universities Cancel Subscriptions to Springer Journals
Funding, or a startup enterprise, is certainly needed to administer the peer review process. I'm willing to bet it would be less than $10 per paper in universal use. No money is needed to pay reviewers. In fact the savings would be so great, their could be a courtesy payment. The ruinous censorship and false ownership of the publishers should be broken.

(1) Someone else in this context refers to anyone other than the author-researcher. The point I am attempting to make is that researchers, as long as they are on an academic grant and salary, and with the prospects of generating millions of dollars of private property, have no incentive to change the system. (2) It is clear that in electronics, biochemistry, and even in my little field, laser physics, the commercial applications overwhelm traditional pure research in degree of economic input, persons employed, turnover, etc. This is true in all hard sciences and life sciences. If it is not true in other fields, do they outweigh the scientific engineering fields? I think not.
agjacobson··on AI Has a Hallucination Problem That's Proving Tough to Fix
I couldn’t resist because everyone’s thinking of cat-guacamole. Also Labsix.

agjacobson··on Sin and Cos: The Programmer's Pals
Exactly. And if you understand what you’re doing, you can avoid referencing the angle explicitly. Because macro arc length is rarely needed.
agjacobson··on Sin and Cos: The Programmer's Pals
The trick with sin and cos is to never use atan (or atan2).
agjacobson··on Adopting a more active lifestyle could benefit your personality decades from now
I found, at least for myself that there was a large opportunity for reversal, when adopting a more active lifestyle in retirement.

Let’s see what he can do with a $10 lunch business model.
agjacobson··on “Invisible Electrostatic Wall” at 3M adhesive tape plant (1996)
Optical physicists and chemists need a laser with a knob on it to tune the laser to an exact desired color. In the 70s and 80s, the preferred method was the use of liquid dyes as the laser medium, typically dissolved in alcohol. The dye was pumped at high speed through quartz cells, and was gotten to lase by striking it with a fixed wavelength green or ultraviolet laser. Now the best practice was to use Teflon tubing. It cleans up better, and that’s important because when changing colors, the new dye’s wavelength might be absorbed by the previous dye residue, if any. Man, the triboelectric shock you can get from high speed flow of alcohol through Teflon! The Livermore Lab was worried about this during the laser isotope separation program, as a fire hazard. The problem is solved by installing stainless steel ground wires in the Teflon tubes.
agjacobson··on Axiom Beta – Digital cinema camera built around FOSS and open hardware
Price point is everything. Good luck.
agjacobson··on Chrome is Not the Standard
I was under the impression that Chrome for IOS was a shell on Safari relying on calls to Safari code. Am I wrong?
agjacobson··on Tumblr is Tumbling
"...Tumblr is the home of some of the most creative online personas..."

Funny. I thought it was a porn site.

Out your piss.
agjacobson··on The beginning of the end for copper wire
“I don’t envision AT&T and Verizon tearing down huge amounts of copper in towns immediately.“ That’s not the point. When failures occur, they stop fixing the wires and send you a letter telling YOU what your new mode of service is, or nothing. There is no tearing down. The unsupported wire is left to rot or be salvaged at their convenience.
agjacobson··on Business questions engineers should ask when interviewing at ML/AI companies
This is silly. You’re the one being evaluated here. Can you code, or are you just a “sophisticated” smartass?

The trick is to find out all these answers WITHOUT asking the interviewer.

agjacobson··on Economic and Academic Consequences of Fraternity Membership
1. Frats select for lower overall academic ability. Few physics, biochem, ee majors. This bleeds over into their easier major. 2. Frats select for larger physical stature and attractiveness. This deselects for academic performance and strongly selects for business success. 3. Most importantly, there is little artistic, creative, or purely intellectual emphasis here. If a young person is dedicated to "going for the money" at an early age, the results are not surprising.

These advantages, while enduring, are likely to reduce with time, in my opinion.

agjacobson··on Avast: Update to the CCleaner 5.33.1612 Security Incident
For the first time ever, CCleaner 5.33.1612 is offered to immediately update, without begging you to upgrade, or trying to show you a video, or anything. The new version is 5.34.6207. The claim is that only the 32-bit version was affected. See http://www.piriform.com/news/release-announcements/2017/9/18...

At least I hope that's what happened.

agjacobson··on We've failed: open access is winning and we must change our approach
The copyright law is absurd in the context of scientific publication. Here's why. The private property associated with the publication is created at the moment of publication, and is the association with the author's name. It is this association with publication which undergirds lifetime tenure, or reputation leading to employment, a cash flow which when discounted can be worth many millions of dollars. The investigator author knows this and the publisher knows this. The author gets permanent monopoly rights due to the association. It's remarkable. Unless the publication is proven wrong, the name association can last centuries. That's why I say many millions of dollars in the case of a significant publication, especially, pre-tenure.

Now the publisher knows this too, and tries to assert monopoly rights, using the skirts of copyright law, over a certain time frame, in the vending of images of the publication. It's ridiculous how little value he's added. And when you examine who paid for the research or work in question, it's a racket. Third world baksheesh is certainly less injurious to progress.

agjacobson··on Is StubHub's Website Deceiving Users?
Many people lack a gut level understanding of this concept: a vendor who deep discounts or sells at cost can generate almost arbitrarily large revenues. For a while.
agjacobson··on Chrome's Plan to Distrust Symantec Certificates
One of the happiest days of my life was when a Symantec support person, very courteously, helped me remove every Symantec product from my computer.
agjacobson··on Don’t Fall for Babylonian Trigonometry Hype
It's not rational trigonometry. The angles are irrational. In fact, it's useless, and was probably a decorative demonstration of Pythagorean triples.
agjacobson··on Examining a vintage RAM chip, I find a counterfeit with a different die inside
Why do you think the 74LS189 was being counterfeited? It was the touch tone chip being counterfeited, and disguised as a 74LS189. The buyer knew the ruse.

agjacobson··on iPhone Bugs Are Too Valuable to Report to Apple
If there's a shortage, or some other performance problem, they do, and they will.
agjacobson··on iPhone Bugs Are Too Valuable to Report to Apple
1. Sell bug on the open market for whatever price the market will bear. Advantage: paid concomitant to your talents. 2. Wait n days. n could be zero. Don't have a theory for n. 3. Slip the bug to Apple anonymously.
agjacobson··on Ask HN: Teaching Code to Someone That Asked Me for a Job
Exactly.
agjacobson··on Ask HN: Teaching Code to Someone That Asked Me for a Job
Coding is a very complex skill. The success probability in going from zero coding experience to being a self-starting coder is a bet I wouldn't take except out of pure friendship or charity.

There are two problems. If you substitute "gardening" above for "coding," my statement is still true. The second is the nature of learning exercises. We all know that a real problem to solve generates motivation that is much more valuable than, and can self-generate syntax and algorithm knowledge.

With all the free tools, free courses, and free pdfs around, I wouldn't try to train someone who is not already brimming with questions generated by real frustration.

agjacobson··on Why do so few people major in computer science?
No attempt was made to measure the number of productive dropouts. I.e. authors bias was "count people with a degree."

Hypothesis, gedanken experiment. Award all hackers who are able to support themselves, not necessarily as developers, but having to do with computers, with a CS degree. The curve fills right in.

agjacobson··on The Boring Company FAQ
This is a little crazy. Because of too much surface traffic, let's bore tunnels and develop sleds. The problem is: inefficient use of the existing infrastructure, 1 person per car, and the like. This wii be improved by the sharing of vehicles, and the driving of vehicles in formations by filing flight paths, using driverless technology. Cars are a highly unattractive investment anyway, a $50,000 car sits unused 23 hours a day. I am also skeptical that right of way, permits, and local governments could ever be satisfied by this scheme. And one pleasure of driving is looking out the window. You want to go in tunnels? By yourself? Oh you will work?

Nahh.
