Not even just lefts; in SF now most[0] lights will show a pedestrian walk sign around 5 seconds before any light in that direction switches from red to green. So pedestrians will have a chance to make themselves seen before cars do anything.

It's also useful if you're a pedestrian going in the perpendicular direction. If your light turns yellow, you still have another 10 seconds to get across (5 seconds for the yellow->red transition, and then another 5 seconds before the opposing light turns green). Granted, this isn't universal (see below), so you still need to pay attention and sometimes hustle across.

[0] Weird that it's not all, but I still see many that turn simultaneously still.
> Most environmentalists want no cars

I don't believe you. Back it up.

> as they should

What percentage of housing stock today where you live is situated where being car-less wouldn't be a major handicap? Make sure to account for people with families, people with vision/mobility issues, people who need to move materials to/from worksites regularly, etc. even if those concerns don't apply to you personally. Reducing the number of cars on the road, and the environmental impact of those that are, is a fine goal over the long term. OTOH, extreme anti-car activism - especially that which is just a cloak for a phobia about driving - quickly makes a mockery of itself.
Guys, what are we going to do? I have the exact same problem. I don't need the high salary anymore but I don't know what to switch to. I't doesn't help being in a country where nothing interesting is happening. How do we find something which feels worth fighting for? I want to work extra hours because it's somthing I believe in but it can't be a webshop backend or an ad optimization engine. Is there something people really need that programmers can help with from around the world? It feels like most issues are political or psychological
This is the technobabble that just drives me insane about this space.
Sort of. EuroNCAP 5 star rating require cars to have automated braking both for in front and passing pedestrians. The amount of times my car have been in emergency mode either warning or actually hitting the brakes because a cyclist seemed to be intersecting with my path I don't know but it is a lot. Not perfect but better than nothing. Especially as many countries tax cars based on safety ratings.
Ask HN: Career (Down) Path for a Principal
Posting from a new account for anonymity.

I'm currently a principal SE. The role/level has its obvious perks (recognition/influence/very well compensated/etc.).

However, I feel some fatigue/burnout from leadership responsibilities. I have been burnt before and know what an ugly place it is.

What are your advice to help bring back some balance? I have considered:

* Taking a long break (up to 6 months).

* Moving down to a senior role and just chill (not exactly sustainable long term if we still want private school for the kids).

I wonder if there are other career paths that may be suitable medium/long term. If so, please enlighten me.
These discussions tend to end up contrasting a handful of large cities with middle of nowhere. You can find plenty of places in maybe the $400K range and probably less than I think an hour of many major coastal cities.
Arguments about blockchain here on HN are frustrating. There are plenty of good examples of where it works very well but the mental gymnastic people go through to deny the obvious are incredible.

The most basic to me is the Automatic Market Maker system. For example Uniswap is a system with only a few (relatively speaking) lines of a code at its core and a team of a couple of dozen. The system does billions of dollars worth of trades every day. If anybody can point out to me a broker that does similar volumes that would allow me to make million-dollar trades with a few lines of code with no possibility of censorship I will happily concede that web3 is a failure.

Oh and BTW, love Helium, just started researching it a few days ago. As always all great projects are easy to dismiss until one can no longer do it. I think I'll get in line for a hotspot/miner.
Nice. It’s starting to spread :)
> This is about reducing harm by reducing infections.

That doesn't make any sense for CP. It's not like people who weren't into that crap before stumble upon it and are like "oh, now this is MY THING."

What I'd propose is having a "known bad content" (as flagged by users/operators) list that gives node operators a rating they can filter what they propagate by.

For example: if you have A, B, C, and D ratings (A being harmless, D being CP), you'd get a self-policing network because node operators could say "I only host/seed B+ content." Very few people given the choice would even want to seed D-rated content (and if I'm wrong, then we have a much bigger problem at a societal level).

It'd be imperfect, but so is blatant censorship. Arguably this approach would help you to find the worst stuff fastest.

That's only true if there are no oncoming cars lined up to turn left in front of you. Even just one car waiting can obscure an oncoming car coming around them to run the light and crash into you as you turn.
Sorry, you specifically called them out ("e.g. China") so I thought you were focusing on them.
There's still friction. Do you know how to do your taxes on international income, CGT, discounting transfer fees, etc? There are services which will do most of that for you, but that's still time to export/import the transactions, ~$50 to get the summary, some more time to deal with actually putting that info on your tax return.

Realistically that's probably 3h of work in a year, but I'd probably pay a bit of money not to have to do it.

AsciiDoc looks like a cool option. I wrote mine in Libre Office Write. Then I wrote a small book with step by step instructions for how to do it.

My first instinct is always to imagine that writing something new will be easier than reading what's already there. The instinct is often wrong, though. Plus, I'm much more likely to learn a new trick by reading than by writing.

> That is a revelation! I never had that training or even knew it existed, and roundabouts are occasionally deployed where I live without implementing any training. The training seems an essential component?

Like for any part of driving a car, training is important for 2 reasons:

- you don't have to think when you are approaching a roundabount. You know where to look, you know what speed (and gear if applicable) you need, you know where lane to go and what signal to use. Since it's a situation with a lot of information, it makes your decision process relaxed and accurate.

- socially, if most drivers are trained, they will behaved consistently, and hence, produce a stress and surprise free experience, but also letting you identify easy the drivers you need to watch out for.

> Any suggestions on where this training might be found (in English)?

I have no idea, it's part of all french drivers training automatically, anywhere you go.
+1. They should start profiling their application. If its running on alpine linux e.g. the default memory allocator is extremely bad and would degrade performance - but it could also be tons of other things. Taking random actions without understanding what the current bottleneck is will never be great long term.
I’m not sure I get your point. VAlves does it with cs:go and dota 2. Players create skins and all, and then vote for the ones they’d like to be incorporated. Sometimes valve incorporates some of the players’ creations.
Very exciting if true but I've seen a lot of hype around Alcubierre drives that either are bogus or not reproducible.

Maybe the solution was to not publish sites that are a bracket off.

I think half the problems with JavaScript are because of its weak typing. 1 + {} should be a type error.
That's seems unnecessarily confusing. Why even bother with the red arrow at all then? I guess it could be useful in cases where the straight-through traffic is green, but you want right-turning traffic to stop before turning, but is that common? Or even a useful thing? Like, I feel like if you've set things up that way, maybe the intersection is just designed poorly.
I'd probably enjoy that as an individual, but it's trickier with a family.
Fyi “Sign-In with Ethereum” is just standardizing the “Connect Wallet” button.
Those side channels existed because because they very clearly violated process isolation. Of course processes aren't going to isolate if your hardware ignores your isolation boundaries.

Enforcing this kind of isolation in software will likely be quite difficult though.
On Chrome/Chromium I can routinely expose myself to youtube ads if I have a video open, close the browser, and re-open with that tab loaded first. I figured it was some conflict in initialization of extensions and the page, but good to know a different extension might not have the problem. Firefox doesn't, which I use for everything but youtube livestreams anyway.
By "actual COVID data", do you mean positive tests? All things considered, I would assume that wastewater data to be a lot less suspectible to biases (eg who gets tested) and random fluctuations (testing on weekends, holidays, etc).
>There's nothing "typical" about COVID19 yet.

Corona viruses are a family of viruses that extends far beyond the particular virus responsible for the current pandemic/epidemic.

Corona viruses are the #2 family responsible for the common (viral) cold, behind rhinoviruses (In the ballpark of 10-20% and 50-60% respectively, iirc, but definitely
rank #2 & #1).

So there is a great deal of historical knowledge about the corona family of viruses, just not necessarily specific to this corona virus and it's variants.

In the context of looking for seasonal patterns in respiratory viruses, it's the first place you'd look in trying to find common traits.

ETA: WebMD says 10-40% Rhino, 20% Corona, 20% RSV/parainfluenza, and 20-30% "other".
It's so bad that this ever existed.

It's even worse than PHP and JS were built around it.

Errors should never pass silently unless explicitly silenced.
Is this satire? Vehicle speed is one of the best predictors of pedestrian fatality and injury severity in an accident. When a pedestrian is struck by a driver, almost nothing else matters as much as the vehicle's speed.
Right. So if we replace plain text then let’s maybe do better than JSON or not do it at all.

Let’s put it this way: if I proposed XML as the substitution for plain text, would you rather keep plain text or switch to XML?
Sorry, I should have been more clear. I believe we use the masking on 32-bit platforms, which is faster than explicit bounds checks. On 64-bit platforms we use guard pages. We don't actually need a signal handler, because we don't need to gracefully recover from a fault like we do on the Web — we can just crash.

Really? The grandparent says it's common in Texas, but in my experience it's pretty common in all of the US (at least in urban and suburban areas), and shouldn't be surprising or odd to anyone who's learned to drive in the US or has been driving here more than a few months.

But I agree with you that you should verify that no one is coming in that case; that's sound advice for most all situations, really.
Spot on - anything else renders software less useful.
It's not about making people pedophiles, it's about giving existing pedophiles material. Or about exposing people with right-leaning views to more and more extreme content, or whatever the dangerous material in question is.

What you are proposing is just censorship with extra steps, it seems to me, where the operators are the censors. What's the point, other than making everything more complicated and difficult to work with?
The first two aren't cars, so that's easy. You don't need to absolutely eliminate vehicles. For disabilities it's more complicated but at the very least you've already cut 90% of traffic.

Not sure also, but in the 00s hosting/registrar control panels were notoriously bad at updating their server configs for some reason. It was not uncommon to wait ~30-60 minutes for the changes to be pushed to the authoritative servers and my guess is that for older IT folks that's where all 'propagation' expectations come from.
Apple replaced the bent iPhones on the spot for free. That said, the iPhone 6 represented peak Jony Ive. I'm glad he's gone. Apple has walked back their obsession with thinness in favor of maximizing utility, all to the benefit of the user.

I came across this when looking for a different program for classifying drum samples graphically with each as a colored point where proximity is related to similarity of the samples. I think it's an ableton plugin.
Valve does it with cs:go and dota2. People submit skins and creations and you can vote. Valve then sometimes accept some of them and integrate them into the game. There’s no reason why players shouldn’t be able to create biomes or structures.
I love using iOS as a mobile Unix device and android as mobile Linux, I feel like it can do everything once you unlock the limited software and have more access to lower levels. They probably think it’s all piracy or it’s their telemetry I’m blocking, but you don’t need to jailbreak to pirate, or to run a VPN and it’s nice to have stuff like https://www.idownloadblog.com/2020/10/15/battsafe/ to never have my battery trickle charge.

Sometimes there’s flaws/glitches in iOS or OS X and they kill battery life or rewrite databases, I was able to diagnose it, I installed top (yes CLI top) and figured it out. I have a full terminal just like my computer, it’s awesome so much Linux CLI has been ported.

> Spike-specific interferon-γ CD8+ and CD4+ T-cell responses were evaluated by intracellular cytokine staining assays and also showed durability and stability over this time period (Figure 1A, lower panels). The median CD8+ T-cell response was 0.0545% on day 57, 0.0554% on day 85, and 0.0734% on day 239; the median CD4+ T-cell responses were 0.0435%, 0.0322%, and 0.0176%, respectively.

I think the goalposts are being moved here. Can we agree the original statement “There is no measurement for T cell immunity though. So you're pointing to something that can't be quantified and that's not scientific.” was incorrect?

Furthermore , “ The study you linked also showed vastly increased neutralizing antibodies, which is in conflict with what was posted here.” Sorry, but your argument would need to be expanded a bit.

Either way, can we also agree your original statement about the “ The vaccine trials were deemed a success due to high levels of neutralizing antibodies” was factually incorrect? You can review the data submitted to the FDA for EUA for both moderna and pfizer and see it was not just about antibodies, but about success in a phase 3 placebo controlled trial against the symptomatic disease in the wild.
They don’t tell you their own telemetry as far as I know.
> He didn't mention the $750m (£565m) cash

I like the BBC but this sort of lazy judgemental journalism annoys me.

The inference here is that because investors put in cash, the business isn’t in trouble and he shouldn’t have to fire anybody.

In all likelihood, the investors had to put in cash because the business is in trouble and it meant he was able to fire less people.

The critique of the zoom thing is unfair too. If he’d brought 900 people on site during a pandemic just to fire them, he’d have been criticised for that.

This is just a manager having to make some incredibly tough calls in very difficult times.

> I wonder what it would take to convince management to do the same.

Build the redo time into your estimates.

Non-technical management has no concept of what's involved in building software. They don't need or particularly want to know. They care about things being "done." You don't need to convince them of anything, you just need to consistently and reliably show progress in a way that they can comprehend.

It's very irritating to see no progress for a month, then see a demo of something that appears to do everything you asked for, then hear that it won't be "ready" (whatever that means) for another month because the whole thing needs to be redone.

It's very reassuring to see demos every two weeks, each one showing an obviously incomplete product, but with clear progress between each demo culminating in a completed and delightful product after two months.

The actual development process for the two scenarios above can be exactly the same, it's just how they're messaged.

This is "managing up."
Depends on which countries. $25k salary here is double of, say, a really good accountant or a senior civil engineer. Taxes are much lower too.

Countries with no unicorns generally pay a lot lower, but there's more potential to do a startup. Everyone in the world deals with taxes, payrolls, and resells cars, but sometimes there's no localized software for that. Companies with corruption have far more financial restrictions and often global companies are reluctant to enter.
It may not be malice, but it is a design decision often made for robustness or future proofing that seems to backfire every time it ends up in a security critical context.
Beginners Guide to Gateways and Proxies
Notably, the self-service and enterprise TOS differ a bit here.

From "Cloudflare Self-Serve Subscription Agreement" https://www.cloudflare.com/terms/ , "2.2 Restrictions. Unless otherwise expressly permitted in writing by Cloudflare, you will not and you have no right to: [...] (f) perform or publish any benchmark tests or analyses relating to the Services without Cloudflare’s written consent;"

From "ENTERPRISE SUBSCRIPTION TERMS OF SERVICE" https://www.cloudflare.com/enterpriseterms/ , "2.3. Restrictions and Acceptable Use. Customer must not: [...] (i) perform or publish any performance or benchmark tests or analyses relating to the Service, other than solely for Customer’s internal use;"

Generally, it sounds like the kind of thing that would be obvious to a lawyer (we want to prohibit random people badmouth our product, right?) but stupid to engineers.

The best outcome would be if Fastly and Cloudflare both dropped any language limiting benchmarking and sharing of results.

If they want to protect their brands, the most common sense requirement would be "We require you to tell us, within X hours after publishing, of benchmarks you're publishing and send us a copy of the article in which you published them (or link if publicly accessible)."
I have some Top Shot moments, and I don't think of them as NFTs at all. As long as it's locked down on one platform, to me it's not an NFT. The get rich hype seems to be at an ebb with them right now, so I can just play around and collect. It's fun, but it's not an NFT.

So far it's a case where I don't think the blockchain is adding any value whatsoever. Blockchain is just a poor fit if you're going to keep it locked down to one administrator.
