Ask HN: Have you ever worn progressive lens eyeglasses?
I've heard people say their favorite form of eyewear is progressive lenses -- but I'm baffled as to how these could work for sustained computer usage. Usually I'm using my laptop, on my lap, and my new progressive lenses seem to never show clear letters except at a certain angle, requiring an uncomfortable tilt of the head.

The conventional wisdom is you get used to them after two weeks and then can't imagine wearing anything. Any HN readers have their own experiences they'd like to share?
Rich people will mainly be impacted by the forced migration of climate refugees from impacted countries. Will they be allowed to emigrate from regions beset by flooding (coastal areas), drought (inland areas), and the resulting crop failures?
It's insightful to see how many comments are about avoiding tax. Companies with an anti-society, screw-the-poor, not-my-problem attitude are exactly the kind of companies that make the world a worse place for everyone - except shareholders and (sometimes) paying customers.

Tax is part of participation in democratic societies, intentionally avoiding it is immoral if you also enjoy the benefits of the same democratic system.

A moderator buried it for reasons explained here: https://news.ycombinator.com/item?id=27305371. Sorry for the delay, but these days you guys need to wait until I'm online to get explicit explanations, because I'm currently the only mod who's posting publicly.
You're confusing the two interpretations of "1.5°C". The calculation you're using is interpreting it as the absolute temperature, relative to Celsius zero (which is not the same as Fahrenheit zero!).

What you actually want to do is find how much Fahrenheit _delta_ is equivalent to a 1.5C delta. Try calculating the Fahrenheit value for 20C, and then for 21.5C, and then subtract.

Or you can look at the equation you're using, where the slope is a clear and constant 9/5. 9/5*1.5 = 2.7
It’s definitely a progress for Instagram but probably a little one if the algorithm sorting is not changed.

For those who may need, there have been browser addons for Twitter and Facebook to do the same. [1]

Also worth noting Mastodon has this demetricator feature built in since quite a while ago.

I'm not sure what you mean. Can you elaborate on that?
Sure, but I’d expect the interpreter to have some smarts to do the right thing within reason.

Interesting. And what was the climate like?
It kind of seems like this article is saying that if we (in 1989) slow global warming by the year 2000, the worst effects of sea level rise will not happen. It's not saying that those effects will happen in the year 2000.

My understanding in 2021 is that much of that stuff is already happening, since we obviously didn't halt warming. And that it's also too late to prevent more of it from happening, because there is a lag time between prevention measures happening, and having an effect.

We are past the point where just reducing emissions will be enough, and instead will need to also harden the world against inevitable effects of climate change. This is even harder and more expensive than it would have been if we had stopped emitting earlier.
Yes...you could run CLI apps just fine on TTL machines. I have a DEC VAX-11/730, which is TTL+2901 Bit slice (so not all 7400) going at about 1/3 MIPS. Runs BSD 4.3 and is on ethernet, and I can develop software (C/C++), chat (IRC), gopher, games (nethack) and even HTML web (lynx). But crypto (TLS) is rough, and things like streaming media and modern web are right out. And it uses a couple of times more power than my dryer does...not very environmentally friendly.

But practically, the limits of a 74xx series in creating a 'modern feature' (like, 32-bit) CPU are manifold. Assuming DIP chips, it would pack an average of 4 logic gates in about 1 sq inch (hand-waving a bit, and including board space). A Cortex-M0 has approx 12,000 gates [1]. So it would be huge. Assuming LS logic, each chip would draw about 4.5mA peak, so about 13.5 amps peak. So it would use a lot of power. Propagation delay (maybe 10ns per gate in LS) means it will be much slower than integrated logic...perhaps a couple of orders of magnitude slower than an M0.

There are mitigations. You could use SMT packages and pack more on a board. You could use a more power-efficient logic family than LS (e.g. ALVT or some CMOS family). Or go for faster logic at the cost of power. But you're never going to get within an order of magnitude or 3 of the speed+efficiencies of a monolithic chip.

There are a number of homebrew TTL CPUs out there for comparison. Most are 4- or 8-bit.

A popular rebuttal to the medieval warm period observation is to claim that it wasn't actually warmer...
I will note I ended up at an institution (admittedly an academic one) that for my field is usually met with "Where?" because the funding allowed for some very nice quality of life considerations and more academic freedom/less pressure to support yourself with grants.

It's not impossible, but you do have to figure out ways to offset the risk and prestige hit.
The “failure” of the CentOS community is really related to the nature of the distro. As they aimed to be a fully compatible clone of RHEL, there’s not much you can allow in terms of community contribution to packages, etc,. Those kind of restrictions don’t lend themselves well to forming a vibrant group of contributors.

The main area that was lacking are the other resources, like wiki, forums, and other docs. That’s one area where criticism is warranted. I always wince when I have to go to the Arch wiki to figure out how to set something up in CentOS.
You're getting a lot of downvotes, but this is legitimately the first time I realized that a 1.5C temperature difference really means a 5 degree difference in Fahrenheit. I think it would genuinely help Americans if this were reported in the scale we were familiar with. A 5 degree F difference sounds far, far more scary than a 2.5 degree C difference.
Their last big performance breakthrough was, IIRC, "now merely wastes as much battery as Chrome, which is itself notoriously wasteful". That after years of eating battery like mad.
The biggest problem with the saw stop is that wood when it is even slightly moist can set it off.

So on a worksite if you are using lumber that hasn't had adequate time to dry the saw stop would trip even without any limbs being in danger.

Each time it would destroy itself, you would have to take the saw apart and change it which would cause a work stoppage.

What irks me the most is that the SawStop owner tried to create legislation that would have required companies to use his product.
What do you mean by "citation"? An academic reference, or an example?

There are examples of these in these comments, so if you doubt that these things are true (and cannot find examples in this thread) then please narrow it down to one - this isn't a wikipedia articles, theres as much burden on you to disprove something you disagree with, and you haven't yet stated you disagree with anything.
Seems like a cool product, congrats on the launch!

this all sounds very tinfoil hat, but that will change too

edit: yes indeed this is consistent with whacko advice for the zombie apocalypse...if governments anywhere were capable of getting in front of climate change, they would have done so at least a decade ago. it is the governments and the systems they support that are making things worse. forget the Paris Accord, Neville Chamberlain had a piece of paper too
This ignores evidence from previous experience.

You could compare with how rich countries handled the pandemic, and then consider that the pandemic was relatively easy with new vaccine candidates almost immediately ready for testing.

Also compare with how we handle various natural disasters. What is California doing about wildfires? The rich people in Malibu still lose their homes.

How about preparing for drought? What is Houston doing about hurricanes? Is Texas ready for the next winter storm?

Rich people will handle this with their own disaster preparation (sometimes) and moving if necessary.
Lived in TW2002 on Atlantis BBS for the better part of 2 years. Good times.

"How it started" (From your Article)

Coastal regions will be inundated; one-sixth of Bangladesh could be flooded, displacing a fourth of its 90 million people. :

* long term support (e.g. don't EOL something just because it's 5 years old, etc)

* immediate support (have someone you can call 24/7 if your system blows up)

* responsive support (have engineers on staff to close support tickets fairly quickly. This applies especially to bugfixes)

* good QA process so that you do not use your enterprise customers as free QA but pay people to test the product thoroughly before releasing it. This ties into the notion of long term support as something that stays in the QA matrix and receives bugfixes/updates.

* good documentation, in multiple languages

* A supporting ecosystem of certifications/training materials, so a business can hire people qualified to use the product

All of the above boils down to having people on staff doing all the boring, costly things that reduce the pain of companies using the software. Those things are not fun, so they tend not to happen consistently by open source volunteers, so they have to be paid for, hence "enterprise", as end users don't value these enough to pay for them over free but big businesses do.

They work poorly (if at all) as currencies:

(1) They're way too volatile.

(2) Even if they weren't, the popular cryptocurrencies today have fixed money supplies. A central bank cannot increase it to target moderate inflation.
You do what most people do when they start companies. They start small, without VC investment. And with the internet, it's easier and cheaper than ever to start one.
Are you sure about that? I’m not sure you are hearing and understanding my suggestion. A review would always consist of one paper being ranked above another one. The tone of the review comments would have no bearing on the usefulness of the review. The reason we even have critiques in reviews is to justify the score that the reviewer assigns. Reviewers are specifically asked to produce reasons. What I’m suggesting is different because reviewers would rank two papers against each other and not be expected to justify their decision, nor would they be asked to provide a magnitude for their opinion. Comments and critiques would be allowed, but there’s no need for harsh reviews.

I’ve seen a lot of overly and unnecessarily harsh reviews. Anonymizing enables over-stating criticism, it happens routinely. I don’t think I agree that harsh critique is necessary for a healthy review system. It is already the case that good reviews are not extremely harsh, they focus on the facts and are willing to stand by their statements. I don’t personally know that many researchers who have trouble being direct in person and face to face, or of offering constructive criticism.

> As a reviewer you are only advising the editor

This completely depends on the journal or conference. Quite a few of them, especially the larger ones, do not override reviews casually nor often. And what I’m suggesting is a system where this idea can change, where editors can more easily trust the review results, and won’t need to override the decision.

> People are petty.

This might well be true. And so I’m not entirely understanding your argument. It seems to be simultaneously suggesting we have a problem, and defending the status quo as the way it needs to be. What would you suggest as a way to improve the review system so that pettiness has less influence than it does today?
Then the statement is worthless! If any country is every covered in water at any point in the earth's future then it can be proved "correct".

The negative is not even true -- no one can guarantee that no countries will ever be covered in water at any point in the future, even if we had presumably gotten the rising temperatures "under control" twenty years ago.
This person probably slowed it down, many users have it ramped up to even more insane speeds.

Conspiratorial Thinking and “Multiple Outs”
Misleading clickbait headline.

Headline should be: "World now likely to hit 1.5 °C rise above pre-industrial levels in the next five years".
I feel seen.
Back then AP didn't publish things on their own. They just sent it out ("dispatched it") to subscribing newspapers.
They have no conflict of interest. Neither Uber nor GMB pay BBC staff in any way.

The only degree to which they benefit is from whether this leads to an overall societal trend that might benefit them. Its unreasonable to expect journalists not to comment on any element of the public sphere that impacts them in some way. E.g. you might as well say BBC staff shouldn't cover the NHS because they get NHS care.
I wasn't attempting to use it as a support forum, more venting after trying it, as I was hoping for something that Just Works(TM) at least for the basic, without me having to spend weeks hacking around with it. I'm quite happy to spend some more time tuning and customising, but only if I get the basics working easily, I'm sure it understands me, and I'm sure it's going to worth the time.

I'm hope you don't think I'm trying to be mean, it was just a really disappointing first experience. Might be my expectations were misaligned.

I had actually already installed the VSCode plugin and restarted both VSCode and Talon (I don't remember if I saw it in a comment in a .talon file, or if I saw it in the console logs, but somewhere it told me to install a plugin). Similarly, I installed the Rider/Idea.

I wasn't quite just saying anything :) Tho it wasn't clear what commands were actually accepted; from looking in the .talon files, I didn't see anything like a string literal, more something code-like. I had to guess at what commands were supported, for example "reload" in Chrome (assuming that's actually a correct command, even that simple command only worked some of the time).

I'm willing to give it another go, but is there a getting starting guide/tutorial for how to get started using it, and how to see what it's actually trying to do when it does something? I used the getting starting guide on the Talon site, but that only tells me how to install it, not actually how to use it.
I'm sorry about my second paragraph. I'm getting a bit antsy from losing an otherwise intelligent friend to this nonsense.
Rehabilitating Nero, an Emperor with a Bad Rap
Who really cares? Didn’t the CIA force the Peruvian President’s plane to land in Austria to look for Assange? That’s a precedent.

Nations have every right to defend themselves from subversion. And this fella’s so obvious in his subversion that he has CIA money bursting from his pockets and has a big giant neon hat that says OPEN SOCIETY SOROS SUBVERTER on it too.
I want to point out that OpenTelemetry is explicitly designed to decouple the API from the SDK, allowing for other people to reimplement parts of the SDK as needed while maintaining compatibility with not only other SDK components, but also the overall ecosystem. This was one of the major changes we introduced as part of the OpenTracing/OpenCensus merger.
It's a little weird to blame the users in the same post that explains how the app is designed to distract you from the healthy usage you advocate.

Am I the only one around here who is old enough to remember this exact prediction from 30 years ago? Florida should have become the next Atlantis 20 years ago. I understand it's a worrisome issue, but like religious predictions of the end of the world, failures work against credibility.
At the time of the Satanic Verses controversy, there was the irony that he wrote things that were anti-colonial and anti-Western... and his life was threatened by third-worlders with a religious philosophy that directly contradicts Western ideas about freedom of speech and religion, while the West had to protect him from those third-worlders.
Most coral atolls have actually been growing. It's been over 30 years since the statement and not one has succumbed.
No, probably not. But then what's the alternative? The prediction is/was accurate, the error is in the kind of apocalyptic outcome it brings to mind. Reality is almost always far more boring. Silence doesn't seem helpful either, nor does being more vague about consequences.

Sea level rise looks more like king tides periodically destroying coastal occupations until it's uninsurable and everyone moves away. Poisioned aquifers resulting in no viable drinking water source and again, everyone leaves. Coastal erosion intensified means small islands with rich histories become nothing more than a sandbar over the course of decades, and sustains no population as it did before.

Chaotic weather looks like wildfires, tornados, and droughts 10, 20, 50% more frequent in their occurrence. But not a new phenomenon. Shit years for various crops become more common than good years because you're not getting enough sun, false springs and shock frosts destroy fruitings, yields are lower across the board. Prices go up. Buying tomatos peak season costs as much as is once did off-season.

Probably the biggest driver of inaction here is that what comes to mind is sudden shocks, yet the truth is more like a slow strangle. The urgency is just as valid if you take the long view, but it's easier to stick with the status quo when it's just the gradual discomfort of a belt tightening and not a gun pointed at your head. Boiled frogs and all that.
I'm curious to understand your use-case, would be open to explaining more?

Do you actually want to overlay the code directly into the parent method or would a tooltip (similar to hyperlink previews) work? I wondering how expanding the real estate space would help with readability and how the userflow would work.

For example, code folding made a lot more sense because the window would have those little boxes to fold unfold (which is basically similar to the act of inline and un-inline).
LOL yeah if I recall I'd have different accounts (I think that was frowned upon?) and play on different BBSes to get my 'hit' :)

I'd remember the days getting stuck in the middle of no where when I'm out of turns and you hope no one comes across you and attack you.

I was in middle school/high school when I played this game...and I'd tie up the house line. Even if I had no turns somethings I'd hang around and chat on the conference with people.

I played a lot on the BBS Family Entertainment (Fament?) I believe...I think that group is still playing and Cruncher is still pretty involved and hosts games.
For what it's worth, I have paid for nearly everything I possibly could with credit cards for decades, and I haven't paid a cent in credit card finance charges in at least 15 years (since my fiancee straightened me out and helped me see that I was being dumb about debt). I have them set to auto-pay the entire balance every pay period.

I use them because consumer protections with other methods aren't as good here in the States. Paying with a credit card, if I have an issue with a vendor, after a good faith effort on my part to resolve the issue, I can just ask the credit card company to deal with it. (I don't abuse this, but I don't doubt there are people who do.)

There are better and worse credit card companies for this. American Express has great customer service but they aren't accepted in as many places.
Oof, not a good look for Mozilla. Totally get the need for $ - but I don't know anybody who would pay for this, esp. with other companies like Google producing so much content around web technologies.
I like Fraidycat: https://fraidyc.at/ (browser plugin, mostly)
>the first thing I want to know is what it actually does, step by step, at low level

I feel like we might be touching on some core differences between the top-down guys and the bottom-up guys. When I read low level code, what I'm trying to do is figure out what this code accomplishes, distinct from "what it's doing". Once I figure it out and can sum up its purpose in a short slogan, I mentally paper over that section with the slogan. Essentially I am reconstructing the higher level narrative from the low level code.

And this is precisely why I advocate for more abstractions with names that describe its behavior; if the structure and the naming of the code provide me with these purposeful slogans for units of work, that's a massive win in terms of effort to comprehend the code. I wonder if how the bottom-up guys understand code is substantially different? Does your mental model of code resolve to "purposeful slogans" as stand-ins for low level code, or does your mental model mostly hold on to the low level detail even when reasoning about the high level?
I love that this prediction has a clear deadline. Now, what skin in the game does the UN have? Will they pay back any government spending that occurs as a result of this prediction if the 1.5C rise does not occur?
Currently the northern hemisphere is closest to the sun during winter months. In the past when it was closest to the sun during summer months (so, hotter), the Sahara was paradoxically a lush savannah. It's possible that warming could affect air currents in a way that makes the Sahara receive dramatically more rainfall that could turn it back into savannah.
