But p - 2 is not the same as p + -2, and it's not clear in your example whether the former suffices or the latter is required. I can definitely imagine examples where the latter is required--certainly C clearly accommodates this usage--but IME it's nonetheless a rare scenario and not something that could, alone, justify always using signed offsets. Pointers are intrinsically neither signed nor unsigned; it's how you use them that matters.

No,not really. I mean, in healthy projects build times are dwarfed by the time it takes to run tests. In web development projects even the delivery and deployment steps dwarf build times.

Very true, but their designers are accomplice to the crime.

I'm generally a nice guy but I harbor uncharacteristically visceral malice toward the a-hole who deemed it appropriate for my Android to let apps or the OS interrupt me by default. If you're that guy and reading this right now I hope you feel ashamed.

Yes, Google has improved tooling and made it easier to snipe out unwanted notifications with precision (and I truly commend them for that), but I'm deeply concerned by the culture of disrespectful interruption that has normalized in the mobile ecosystem. Out of the box on a fresh install there's still way too much superfluous chuff and it takes month being subjected to it and correcting the behavior before I finally have some level of confidence my phone has been housebroken. It's more painful than teaching a puppy not to crap on the carpet.

And it's spreading to other "smart" devices. My Roomba work me up with a chime at 3am last night to tell me it's out of battery after it got stuck somewhere the previous afternoon. (Turns out she "fell off a cliff" in my single-story apartment).

Vendors: You aren't as important as you think. You really aren't.

I wish Google and Apple let me bill publishers for my attention - maybe a fraction of a cent for every notification that's dismissed without interaction. That might finally incentivize them toward more judicial and thoughtful use of the "poke and prod" finger the platforms granted them.

> I think most people who are in the vicinity of a news story irl have such experiences

What's funny though is that although this is true, we still tend to believe all other news stories as though they are 100% true.
Glad we agree on the essentials. There was anecdotal evidence to back up the claim, however; it's not "unfounded." While that's not enough evidence to make any real claims, it is enough evidence to have a conversation.

A conversation is a prelude to an exploration, and an exploration is a prelude to a hypothesis, which is the beginning of an experiment. An experiment is where we obtain the evidence to begin to say that it might be true, or false.

It's entirely possible to think about something and even discuss it without labeling it as either true or false - to be simply agnostic. We don't need to jump to conclusions. If we aren't jumping to conclusions, then it would be incorrect to say that we treat it as false, just as it would be incorrect to say that we treat it as true.

> One clear problem for Optimizely in this space is that experience optimization became a function of marketing departments through out the years but for a while they were positioning themselves as a developer tool. This go-to-market strategy opened a lot of opportunities for other players who saw a bigger market when selling the same type of solution to Marketing Departments.

I can't speak for all industries, but for the ones I'm familiar with, marketing is always the product owner of websites. With two practical implications being

1. The entire website costs (development + software vendors) ultimately get booked against their budget, so they have the true purchasing authority for pretty much all the website tech that isn't centrally mandated/controlled

2. Website projects (including budget and requirements planning) tend to start in marketing loooonnnggg before a tech resource gets brought in. So developer awareness/familiarity ends up moot, since there's too much incremental effort and cost involved for it to be easily get buy-in and added to the plan at this stage.

It makes a ton of sense to target your solution at them instead of developers. They may not be able to use your product well or do the implementation, but they're the ones with the purchasing authority and ability to ensure the budget accounts for it. And can add it into the project requirements far earlier in the planning stage than when tech resources get involved.

I always assumed getting sun(in moderation) was good for oneself. As much as I dislike the heat in general, I always have way more energy after spending a few hours in the sun. I assume(perhaps incorrectly) this was due to a Vitamin D bump.

Further, I've known two people in my life who get weird skin issues if they stay out of the sun too long. My wife is one of them! Really weird, considering how damaging the sun is considered.
>regulating attention is the problem.

Thanks for your comment. I see this in my son, who shows signs of having ADHD. He is able to hyper focus on areas of interest which seems contrary to having ADHD. Less desired areas of interest are much harder for him to deeply focus. I try to see this as an advantage and hope that someday he will be able to exploit his hyper focus and learn to manage his distracatablity.

This seems like a well-researched article.

But I've read an article or two from the New Yorker before in my area of expertise-- music-- where I noticed logical flaws and spurious arguments. According to the well-known Gell-Mann Amnesia effect-- an effect which gets posted on HN like clockwork on any story wrt journalism (which I proudly continue here)-- I should therefore reject this article out of hand.

People who incessantly paste links to the Gell-Mann Amnesia effect-- am I generously interpretating the Gell-Mann Amnesia effect here? If not, what am I missing?
> First off, who would offer insurance to individual police other than the police union?

Presumably the same institutions that offer other forms of professional liability insurance. I wouldn't be surprised if the police union offered insurance, but they will have to compete with other insurers in the market. In this scheme, though, if they fail to adequately adjust for an officer's risk then they will either lose money or they will have to overcharge safer officers. The likely reality is that low risk officers would flee to the cheapest insurance and the police union would be unable to protect the riskier officers from higher premiums due to the lack of low-risk officers to balance out the pool.

Hydroxychloroquine is a zinc ionophore which helps zinc get into the cells in your lungs and slows the viral replication. It was not designed to be used this way, it just happens to work. This is mostly useful before your viral load is high. Same goes for Quercetin, also a zinc ionophore. They are good proactive measures to slow down the viral transcription before you reach a critical stage. It won't help everyone, especially if given late in their infection and especially if their immune system is compromised or otherwise dysfunctional.

I was thinking on creating a turn-based multiplayer game for group chat in an app like Telegram. Then, whenever a player gave a command the server would draw the board and send the updated image to the chat.

It could start with something simple like tic-tac-toe and only two players. A player would tell the app a number between 1 and 9 corresponding to the place he/she chose. Then the server/bot would send the updated image to the conversation.

Don't think that just because you're your own editor you can't be deceived by editing. You're feeding yourself with the material that you're seeking out.

edit: just spend a day only looking up the millions peacefully marching, rather than the 10s of right-wing livestreams. (Also, give me some information about the people you've seen attacking and burning private residences, because I don't know of a single example of this.)

After the day you can go back to watching what you normally watch, but if you can't find all of these boring people walking through the streets with signs, I don't know what to tell you. If the millions protesting actually had the aim of burning middle-class people out of their homes, middle-class people would have been burned out of their homes.

If there's any problem imo, it's that the protests are generally unfocused street wandering. If there were a specific focus or target, they would be effective at accomplishing that target. But when the target becomes anything other than generalized racism, the ad-hoc coalitions fall apart.

Without significant government ran/funded geoengineering projects we'll be living with at least ~1.5 C above pre-industrial levels. We'll need to do some adaptation as is.

Others have mentioned the efficiency of cooling individual rooms instead of the entire home so I'll skip that. (Not to mention that in Korea and Japan, halls are considered "outdoors" and are not heated or cooled, which is a massive waste of energy for the few seconds that people spend in the hallways.)

My issue is that any place I've lived with central AC (or a condo with a fan coil unit) is that when it's actually hot, the central units don't have enough capacity to cool my unit down enough and don't provide enough control. It's like the old cable modem congestion problem where the whole neighbourhood slows down during peak times.

Heat is even worse; when buildings are heated centrally they're usually much too warm in the winter and I end up with my balcony door opened to let the heat escape. Vastly less efficient than letting me heat my own unit.

By forcing people to heat and cool only their units as required, people either get the exact temperature they want, or will accept a non-ideal temperature and supplement with fans to save money.
What's missing from the description of a district heating paradise in Russia (ex USSR really) are constant issues with hot water / heat availability throughout the year. It's not unheard of cities shutting down central hot water supply for months for maintenance, or breakdowns of central heating in the middle of the harsh winter. The further you go from regional centers, the worse situation gets. The temperature that you get in your apartment out of this system is also inconsistent, and depends on a variety of issues with aged infrastructure.

My family lives in a relatively small town in Ukraine, got fed up with that and installed a gas-powered heater that serves both heating and hot water. This setup is 15+ years old already, never looked back. When the rest of the building is freezing cold, it just works.

Mia culpa as others pointed out, the i7-10710U was a Comet Lake part rather than Ice Lake. Seems even more glaring then that Intel had a 6-core U-series chip and now no longer offers one.

That said, also agreed with everyone that core count isn't absolute and we should be looking at the clock frequency, etc. One metric I'm curious to know more is sustained performance - e.g. if the chip can only hit its turbo for <30secs, then that just isn't very good...

It is not that difficult.

In the world of internet, there are many prolific writers who have lived very public lives. There are quite a few specific opinion/news writers who I've read long enough to know their biases or the lack there of, depending on what they are reporting. These individual actors being the feet-on-the-ground lends a large amount of credibility to them as well.

At this point, I think it is just semantics. You can call it a crash, I would call it a dip.

Mostly because I cannot seriously call it a crash (in a way that most people think about crashes), if just a few months later the market looks like as it never even happened in the first place. When I think of a "real" crash, I think of something the effects of which are still present for at least a year or more after the dip.

But that's just my personal take on it, I do not expect everyone to agree with this interpretation of what constitutes a "real" crash.
