3JPLW··on Explanation of the state of uBlock Origin and other blockers for Safari
I installed Adguard myself after reading this post — it appears as though they've split the functionality into many extensions, and only a few require full-page access. I'm trying it without those "advanced" extensions enabled and it seems to be doing just fine.
3JPLW··on Keybase and Stellar Partner on XLM Airdrop Worth $118M
It's like Pied Piper, but with cryptography instead of compression!
3JPLW··on Keybase and Stellar Partner on XLM Airdrop Worth $118M
Yes, I get that. So is Keybase banking on XLM itself to drive their revenue?
3JPLW··on Keybase and Stellar Partner on XLM Airdrop Worth $118M
When I first saw this I just assumed it was some sort of spam/scam. What's the rationale for giving away money here? Is it purely Keybase/Stellar marketing?

How is Keybase planning on making money?

3JPLW··on Keybase and Stellar Partner on XLM Airdrop Worth $118M
It's actually pretty scary giving out money (in any form) to international peoples potentially sanctioned by OFAC. Making it their problem through an EULA is an interesting strategy.
3JPLW··on Stellar just sent 100M Lumens (worth $5M USD) to 300k Keybase users
How does compromising a GitHub or HN account compromise the linked Keybase account? Yes, you can link to those accounts on Keybase, but the trust relationship is going the other way: Keybase is proving that you had access to those accounts (on a particular day).
3JPLW··on A Message about iOS Security
I mean, it is by definition defensive. They're pushing back against some of P0's claims.

Project Zero (whether it's housed at Google or not) has a vested interest in making their detections as newsworthy as possible. Apple has a vested interest in downplaying those claims as much as possible.

3JPLW··on 42 is found to be the sum of three cubes
Yes. The joke the original commenter is playing is that Fermat's `x³ + y³ = z³` is equivalent to `x³ + y³ + (-z)³ = 0`.
3JPLW··on 42 is found to be the sum of three cubes
Yes. 0³+0³+0³. Or x³+(-x)³+0³.
3JPLW··on OpenBSD was right to disable hyperthreading [video]
Have there been any rumors of internal discovery at Intel prior to any of these disclosures?
3JPLW··on Harvard Student Says He Was Barred From U.S. Over Friends’ Social Media Posts
Yeah, I'm sure that will go over well.

"No, I don't have a Facebook, Twitter, or Instagram account, but I do have an account on this site called Hacker News."

"Oh, so are you a hacker?"

Good luck.

3JPLW··on Show HN: Wave-based non-line-of-sight computational imaging in Julia
Not color, but reflectivity.
3JPLW··on Show HN: Wave-based non-line-of-sight computational imaging in Julia
This site — which appears to be the source data for OP as well — has some really nice visualizations. It looks like it's more a scan than a flash, combined with extraordinarily fast frame rates to precisely measure the light's travel time and allow for reconstruction.

3JPLW··on The ‘circle of trust’ behind the world’s first gene-edited babies
> I'm not one for history; so the moral implication of not having a physical-feature-group of humanity around, be it freckles, blue eyes, brown hair, light skinned, tall people or whatever, is entirely lost on me.

It might be worth reconsidering that viewpoint. As you say, we're good at hate. We've been good at it, too.

We've seen that something as simple as preferring male children to female children has dramatic societal consequences. It might be reasonable to decide you want to bias your child against being left-handed — lefties do have higher rates of accidents due to using right-handed tools after all. What might the societal shifts be as a result? Might we effectively loose some diversity of _thought_ and progress in our society at large? How might remaining lefties be perceived?

3JPLW··on The ‘circle of trust’ behind the world’s first gene-edited babies
It's not just skin color, though. It's height. It's face structure. It's the fact that some Sneeches have stars while others are without thars. It's a natural diversity of _everything_. Yes some aspects of that diversity are devastating congenital issues, but IMO we're not ready — socially or technically — for such power to be safely applied through gene editing.
3JPLW··on What happens when you launch Google Chrome for the first time?
An auto-updating browser is essential to me. For nearly all other software I abhor automatic updates, but for something as vulnerable as a browser it's absolutely crucial.
3JPLW··on The ‘circle of trust’ behind the world’s first gene-edited babies
I saw the parent's comment more countering the grandparent's assertion that He Jiankui will be lauded. He will not.

He may go down in history, but he will appear in the ethics chapter alongside Dr. Rascher and will not be lauded.

3JPLW··on 16M Americans will vote on hackable paperless machines
In the US passports — our only national photo ID — are $145.
3JPLW··on CTVT – A contagious cancer that spreads from dog to dog
The third paragraph:

> To clarify, several cancers can be caused by infectious entities; cervical cancer, for example, is the work of HPV, a sexually transmitted virus. But in those cases, the cancer itself is not infectious and cannot spread. CTVT is different: Each cancer cell is a free-living parasite that can set up another tumor on another dog.

Put another way, HPV is a virus whose effects can cause cancer. That is, it causes mutations in _your own_ cells that cause them to become cancerous.

CTVT is essentially a parasitic cell line — not your cells hopping a ride on you.

3JPLW··on WeWork isn’t a tech company; it’s a soap opera
The whole company is premised upon a conflict of interest. They rent space from the founder. What's another 5.9 million between friends?
3JPLW··on Yield Curves Invert in U.S., U.K
This is what I've been seeing, too. If everyone is expecting a recession, then the recession gets "priced into" the current valuations. The big trouble comes if the expectations/pricings are off in some sector.
3JPLW··on Legit-Looking iPhone Lightning Cables Will Hijack Your Computer
On a Mac, wouldn't this cause a "please identify this keyboard by pressing the key next to the shift key" prompt?
3JPLW··on Legit-Looking iPhone Lightning Cables Will Hijack Your Computer
I've not found many details about how this is actually working — there's some info on his D̴̹̭͂ë̷̗́̃̿̓̾͜ṃ̸͔͚̗̙̪̎̄̋ȏ̸̝̤̱͜n̶͇͇͙̻̩͑͑S̴̳̩̮̥͚̥̚ė̸̟̃͋͂͝e̷̪̲̪̰̣̿̀͠d̵̡̂͗ cable here [1], but apparently the O.MG cable is "a very different piece of hardware that does a whole lot more."

Does anyone have any insight into how this attack works? My guess is that it acts like a hub that exposes both the iPhone lightning connector and a keyboard/mouse. And then the keyboard/mouse is controllable via some near-range wireless like WiFi or bluetooth? I suppose it could even scan for open networks and try to join to allow a more remote exploit. Anyone find more information anywhere?

3JPLW··on JPG vs. PNG vs. GIF vs. SVG
It'll work without Javascript if you already have the image cached.
3JPLW··on JPG vs. PNG vs. GIF vs. SVG
It requires javascript from a third party domain. Hah.
3JPLW··on A Boeing Code Leak Exposes Security Flaws Deep in a 787's Guts
Said bad actors probably already have access to the source — or could get it if they wanted it.
3JPLW··on Supercentenarians are concentrated into regions with no birth certificates
Note that you can use tooth enamel, which freezes its carbon at time of development (instead of death). https://news.ycombinator.com/item?id=20627335

That said, the error bars are simply too large to do anything reasonable for dates prior to 1955. The difference between 80 years and 110 years is 98.7% vs. 99.0% of the original C14 concentration... and while you may be able to get a very precise measurement of the remaining C14 you also need to very precisely know the baseline from that era to determine the percentage. Thus typical radiocarbon error bars are at least ±60 years.

3JPLW··on Supercentenarians are concentrated into regions with no birth certificates
Apparently it is possible to do radiocarbon dating on tooth enamel. Enamel contains 0.4% carbon and is indeed frozen at time of development. Unfortunately, we're limited to post-nuclear testing because without the atmospheric diffusion C14 has very low precision due to the half-life of 5730 years.

3JPLW··on Yelp Is Replacing Restaurants’ Phone Numbers So Grubhub Can Take a Cut
How does your anecdote of dining at a hot new restaurant refute the challenges restaurants are facing with GrubHub's fees getting tacked onto typical phone-in orders?
3JPLW··on Disassembling the Sony FE 135mm F/1.8 GM
If you enjoyed this, you'll probably also really enjoy the video teardown of the Sony OSS 16-50mm kit lens. It's cool for two reasons — one is that it's a zoom lens, but the really awesome part is that it has an optical stabilization element. There's also a bit more focus on the electronics and motors.
