I'm questioning the idea that this particular biomarker - doesn't actually mark what the report claims it marks (mitochondrial bio-genesis).

How do we often test for diabetes.. cancers.. many many clinical conditions? Biomarkers. So they are not practically unreliable in general.

What do you know about the particular biomarker employed in the study to say that it is unreliable ?
This is silly. One of my personal stupid mistakes in Python is forgetting to delete a trailing comma. The resulting code is still valid, because a trailing comma produces a tuple.

How is a heads up display "accessible" for people with limited vision? In the web industry, we kill ourselves to make every color combination fully ADA compliant (in the US) and this involves a limited set of combinations. Not being familiar with the auto industry regulations (does ADA even apply?), I wonder how they (heads up displays) or even touchscreens could be considered accessible. Anyone have insight into how this works? Is the user possessing an active drivers license considered enough to exempt automakers from making their controls accessible to people "with disabilities".

Edit: May have found my own answers. ADA guidlines only apply to buses and other vehicles of that type: https://www.access-board.gov/guidelines-and-standards/transp... And most likely, not the operators.
Everything comes at a cost, though. You use the services of large corporations because they are some of the only structures that can present such convenience. But then you end up in a world where most people are pauperized and no longer have any bargaining power in the face of these changes. You end up in a situation where you have entire cities prostrating themselves in front of Amazon so that they might deign install themselves there.

The incentives are aligned for now, until the venus flytrap snaps shut are you wake up to a wall of monopolies all around you.
Last year, I would have discounted that as impossible, but, well, B737MAX.
Hey! This happened on Sunday in my wife's CRV! We were going to lunch, and the touchscreen went apeshit, flipping between menus at the speed of light, beeping madly.

And, as you said, she immediately began fooling with it, trying to get it to stop. I had to tell her "Let me do this! You just drive!" Its very, very distracting.
Why doesn't Google get rid of SMS recovery completely? It's a huge security flaw that can be easily exploited.
Posting because I recently had this happen to me with a rental we booked through Airbnb. Our negative review was scrubbed after two weeks and the entire reservation history has been removed from our account.
I can absolutely confirm this. I have done work (not on this particular type of system, however) for many small-to-medium car dealerships, and they will spend roughly $400 to equip many of the vehicles in their inventory with ignition interlocks that can be disabled remotely.

Here is their business cycle:

1. Purchase a used car from a customer for 80% of "fair market value."

2. Sell the car on a $0-down, 7-year note for 110% of "fair market value."

3. Undoubtedly the loan goes into arrears, and the dealer will disable the ignition system after a certain amount of time. The "owner" will be billed for the tow as well as multiple "recovery fees."

4. Sell the car again for 110% of "fair market value."

5. Repeat.

Multiple times I have been told "we don't want them to pay off the car; we make less money that way."

I remember one particular dealer bragging to me about the fact that he had sold a 2009 Honda Civic 11 times in 4 years. That is, 11 sales and 10 repossessions over the course of 4 years. The saddest part was hearing that over 70% of their car notes would go into arrears within 4 months.
Many people comment under your message that Uber benefits from captured market shares and network effect. In this regard, the following article https://hbr.org/2019/01/why-some-platforms-thrive-and-others... (posted here a week ago https://news.ycombinator.com/item?id=20142912) can be of interest.

In summary, the article argues that some platforms, such as Uber, benefit far less than others (such as Amazon, AirBnB) from network effects due to the fact that their userbases are clustered over multiple locations :

> Drivers in Boston care mostly about the number of riders in Boston, and riders in Boston care mostly about drivers in Boston. Except for frequent travelers, no one in Boston cares much about the number of drivers and riders in, say, San Francisco. This makes it easy for another ride-sharing service to reach critical mass in a local market and take off through a differentiated offer such as a lower price.

The article raises others points and is quite an interesting read in itself. Strongly recommended.
CarPlay might be good, never tried it, but Android Auto isn't all that impressive, whether there is touch screen or not. I did not find it any more impressive with a touchscreen, though.

But I think the bigger problem is that even if touchscreen were a better way of integrating with a phone, it's still a completely wrong way of interacting with anything in a moving vehicle. At least with Audi's classic MMI I could control almost everything without looking at buttons or screen (well, can't quite input addresses that way, but you shouldn't do it while driving anyway). Even apart from all the privacy-sucking implications of at least Android Auto, running infotainment through the phone with touchscreen interface sounds like a terrible idea.

Why can't a 28 American with an English major do a coding bootcamp and find an entry level job? I'm sure if he's reasonable intelligent and ambitious he can. There aren't that many h1b's around competing with him, most American jobs aren't h1b jobs.
You'd need to put that as a 4th year class - if you do it first semester, people would run the numbers and start asking questions.
I think that's better than nothing, I have a friend that he lived in Milano thanks to that.

Nobody wanted to hire him (cash in hand / illegal), and the only way to make anything was delivering food while he's status changed to permanent.
Sure, but that could be a problem for any number of different reasons, and the article doesn’t provide any insight into what they might be.

Are people being deceived in some way into thinking that particular degrees are more marketable than they actually are?

Are degrees that are thought to be very marketable (and perhaps once were) no longer very marketable?

Are people knowingly choosing to do degrees that are known to be unmarketable?

All of those things are completely different problems. The article doesn’t give me any insight into what the problem might be, and doesn’t actually provide much more insight than I could have gotten from looking at two graphs.
The problem is getting worse. It used to be hard to get 5 year loans for new cars. 8 year loans are pretty common. With the vehicle failing to reach the loan's end of life these new loans roll in the old loan's deficiency until someone defaults.

A still relevant earlier discussion: https://news.ycombinator.com/item?id=14476381
In many cars that's easy to fix. Just replace one relay with a jumper. Standard wire terminals fit in the relay sockets so it's not a permanent modification.
I’ll take 2 excellent examples over a definition and one opaque and unmotivated example any day (which is what you get in a lot of papers).
U2F keys are great but I look forward to the day when they’re more widely available outside the US. And I’m still waiting for my replacement from Feitian for the recent vulnerability. Not to say you shouldn’t use them, but... they have their limits. Particularly Advanced Protection which forces you to use Google’s browser in many situations and disables API access so I can’t use the API to get my own data, only Google’s official apps and a small exception for Apple’s.

You only need one reality <-> virtual desync to cause a crash.
I would say that for the average user sms 2FA is secure enough.

P.S. I might have a different perspective as where i am from, there really aren't important services (banks etc.) that are using sms 2FA. Mobile operators doesn't ship SIM cards over mail, you can get a new SIM only in person providing ID (or PIN/PUK in case of prepaid cards). Probably my country is just too small market for these kind of attacks so i feel secure enough when using sms 2FA.
If that's the solution you're willing to deal with you can just not connect to the router in the first place. That's what I did with my new Fire TV but it does kill almost all the smart TV features like streaming and voice controls.

Perhaps people with limited vision shouldn't be driving.

The fact that ACH is slow is a feature not a bug. Remember that when people want to speed up money transfers.

I dunno, I work in a bank and here being semi-openly cynical and greedy is not seen as faux-pas.

Not to mention that part of being a successful person is being able to fake whatever needs to be faked in a given environment if necessary - be it passion, impact or whatever.

Bullshit. There has never been a time when riding in a taxi in NYC was pleasant. It was always a terrible experience. And not just in contrast to better options, it’s objectively bad and always has been.

My theory is that it’s because there’s no incentive for any individual driver to improve. The odds of getting the same driver twice is effectively nil so all they care about is not getting in trouble with the owners or the taxi commission. Outside of that, anything to improve the service is a cost borne solely by them which is not worth it.
Which do you think is more valuable knowledge, solving for x or summing the columns in an excel spreadsheet?

I've owned six Mazda vehicles over the past 30 years. Current owner of a 2016 CX-9. The stock behaviour was that the touchscreen doesn't accept touches unless the vehicle is stopped -- though it doesn't require you to put the vehicle in park.

Also, the vehicle has a heads-up-display projected on the windshield. The original HUD included a graphical tachometer so you could see the revs which has limited value except it looked cool and gave you some indication on when you were in boost. In a future update Mazda removed the graphical tach in the HUD citing safety as they felt the constant animating tach in the driver's field of view was a distraction. But, the tach remains displayed if you had it turned on before the update.

The voice command functionality is okay, including for the mediocre built-in navigation, once you learn the specific phrases and commands.

Last fall I upgraded to Apple CarPlay and the behaviour is the same. Touch input only works when the vehicle is stopped. There was a rumour that one of the reasons why CarPlay took so long to come to Mazda vehicles was because Mazda wanted integration with it's rotary command nob, back button, and other function buttons around the knob and on the steering wheel. Not sure if it's true, but I will say that navigating CarPlay with the knob is just fine when driving, and the physical back button allows me to navigate to the previous screen regardless of whether the previous screen is a CarPlay screen or one of the Mazda screens, which is really great.

I know some Mazda owners were upset with these limitations, complaining that it prevented the passenger from operating the screen, but that seems like a corner case.
Why not "defend" yourself by not relying on gmail? It's not exactly the first time this has happened.
From the HN submission title it wasn't obvious that the issue is people misunderstanding that the ^ operator isn't the exponential operator but the XOR operator. Clicking through made it clear.

Warning about constant subexpressions where the LHS and RHS of ^ are constant literals makes a lot of sense to me, but if the LHS is a constant expression but not a constant literal, then not so much. Also, warning about this will cause some false positives where macro expansions are involved -- probably not a good thing.

This isn't an article about the morality of student loans. It's about the economy. If the economy is struggling because of people unable to pay student loans, that's a problem.

Uh huh, what about "the vertically centered div" and the ever important "span vertically centered within the parent"
A few suggestions:

1) Call your cellphone carrier and ask to set up a password/PIN to be used for when you call into the customer service phone number.

2) Consider your phone number and SIM card insecure. The phone carriers are ignoring the SIM swap problem even though they know how much damage it's causing. Give your phone number to as few companies as possible. Phone services such as Google Voice work without a SIM card, so they are less prone to problems. Give out such a phone number if necessary.

3) Don't use text message verification codes as 2FA. Use an authentication app, such as Google Authenticator.

4) You can retake possession of your hacked Gmail account by providing one of the previously used passwords. No need to have a working phone.

5) Ask yourself, what will happen if you lose both your laptop and your phone at once? Do you have things set up in a way where you can get back into your digital life? Someone can break into your home while you're away, the government can confiscate them at the airport, etc.

6) Check what email addresses you have configured as backup auth methods for your Gmail. Those accounts can be used as a means of access by a hacker.
>> I know that many death estimates for Chernobyl are highly exaggerated, but sticking to the official Soviet death toll of 31 seems ludicrous.

That's the immediate death toll from radiation poisoning, not the total years lost as a result of radiation exposure. The article is correct to point out however that the total death toll must be much less than many other disasters and certainly not comparable to what people commonly believe about the death toll at chernobyl.

>>- Lyudmilla Ignatenko existed in real life and there are interviews with her telling how they didn't let her hug her husband at the hospital due to radioactivity, and she had to hid her pregnancy to be let in. Of course she could be lying, but those would be strange lies to tell.

>> If victims could not be radioactive, why were they buried in metal caskets covered in concrete? This is well documented and there are photos.

Those were firefighters who ingested radioactive products in the air. Normal human tissue cannot be induced to be become radioactive. I'm not surprised that they would quarantine a firefighter and bury his body in a metal casket but that doesn't apply to the majority of the victims of radiation poising by Chernobyl. The show at one point shows such a burial for liquidators who wouldn't have radioactive material in their body and is almost certainly ahistorical. The show never makes this clear.

>>- There are photos of radiation victims from various incidents and they look not unlike what is seen in the series. Here are some (trigger warning, very graphic images): https://imgur.com/gallery/3x7RcLk#QrTJTm5

He was literally standing over a tank of radioactive material when the accident occurred thus explaining the extent of his skin damage. The radiation exposure for the firefighters wouldn't have caused them to suffer skin damage to the same extent and not in the way portrayed in the film. The ingested fission products would have harmed internal tissue before reaching the surface of the body. The show's portrayal of the first responder firefighters is almost entirely completely wrong.

>>There may be things to criticize about the show but this person looks like he is telling a quite biased story.

I disagree and I'm quite concerned about how the show mistakenly portrays the effects of radiation. At the very least they could explained how radiation works and why the firefighters had to quarantined but they never do anything like that. Instead, we hear dramatic warnings of a thermonuclear blast unless our heroes take immediate action which is completely nonsensical.
Cyclists who claim to ride slowly on pavements very rarely actually cycle at 3-4 mph, bikes are pretty unstable. Get a handlebar in your got at 8mph and you'll know about it. Even as low speed a piece of tubular metal in your abdomen is more painful than someone brushing a hip.

If you configure the encoder for lossless compression (-crf 0) then it won't quantize the image data. There might be rounding errors in the DCT, but it's pretty close to lossless. And there might still be a loss of data in other stages of processing, like converting RGB to YUV 4:2:0 or something.

Look for "Marine Cloud Brightening" and "ship tracks". Dirty fuels contribute to low cloud formation -- these are known to partially mitigate warming effects.

The opportunity is to design a jet to spray salt water off the back of cargo ships to optimize marine cloud formation/brightening around the world. This is one of the most palatable geoengineering solutions out there.

As a metaphor for triangulation, "cell towers pump out location" is a passable first-order approximation, even though the infrastructure is far more complex.
This is a key point. With physical controls, you learn their location and use them without looking. This leads to better focus on driving. With a touch screen, you're distracted every time you need to use it.

Not everyone.

I've always had a horrible sense of direction. I can follow a road or a map, but if I take a wrong turn or otherwise get off track, I get completely disoriented, and it's extremely stressful to me. I also seem to have a poor working memory that makes it hard to remember many steps at a time. I often need many drives over many months along the same route to finally etch it into my brain.

With GPS, I'm much calmer and less anxious, and more willing to take risks with alternate routes.
I have no idea what the pros and cons are and certainly can’t speak for why. However, I think the existence of the Advanced Protection Program is definitely acknowledgment that the SMS backup is not secure enough for everyone.

The thing is, not long ago I had no issue recovering my account if it got compromised. I think attackers today have gotten better at finding ways to beat the system. One thing I’ve seen, albeit I don’t know if it works on Google accounts, is enabling high security after stealing an account, effectively making recovery very hard.

Though, I can’t really speculate on if that’s what’s going on here.
Is it definitely ad blockers or have rates also dropped?
