It sure looks nice, but I feel too much screen estate are used to show feed list and article list: while I haven't measured it, it looks like only around 1/4 of the area is used for article content. and the article content is why you want to use a feed reader in the first place.

For me to consider using this feed reader, the area for the actual contents should have at least the same area as the article list. Possibly even swap the two areas.
But when the hostile observer will arrive to another end of a wormhole, the spaceship that had entered on that end has already exited from the other end.

What I don't understand is this time travel thing. Two events can happen simultaneously here and on Proxima Centaur, and both observers here and there will see that event in another system with 4 year delay. So what? Just like a speed of sound lags behind the speed of light, speed of light will just lag behind the actual events that take place. How is this time travel?
For me, YouTube is literally the same - I get the same videos thrown into my feed in repeat. Apparently this converts well for YT and the result is that my feed is maybe 10% genuine discovery. The rest is shit.
Can someone explain to me, what actually constitutes that a particle has information or has no information? I.e., what would actually cause a change of this state?

I would expect, that having just 0 or 1 alone would not. Maybe it is related to an observer/environment, i.e. the reduction of the wave superposition to certain possible states...
The reason we can’t predict the outcome of an N-body problem is that arbitrarily small mistakes radically change the result, the maths itself is fine.

Quantum mechanics, as several other commenters have observed, is where to look for the fundamental unpredictability.

I wonder how long it takes for the quantum uncertainty of a planet to become macroscopic due to the chaotic behaviour in N-body problems…
> that is generally not the case with modern engines (of course, there will always be exceptions)

In my experience, the exceptions are more than the straightforward queries I can write and forget, so much that SQL grammar feels like the German grammar: Here's what you use in this scenario, except [goes on to list a million exception cases most of which makes no logical sense].

This is especially true if you are doing complicated queries across products in a multi-product multi-tenant multi-team database. Writing the idiomatic query takes a few minutes, then hours of fighting against the query planner.

Going bonkers with left joins and/or CTEs usually "fixes" the "problem". I usually leave a commented-out sane version after me for the people who can do better, and not to be blamed with writing mortgage-code.

Neither German nor SQL (with any RDBMS) is my native language anyway, so I can publicly admit my struggles without feeling too embarrassed :)

So we got rid of browser plugins like flash because they were "unsafe" and we "magically" couldn't "sandbox" them for a decade. Then somehow we come up with a new thing that is "sandboxed" (trust us, it is, because WASM!), so let's use that instead and recompile arbitrary binary plugins for that and run it in the browser (what could go wrong).

Really, without all the details/nuance, it sounds like we shot ourselves in the foot, went down a wrong path because of it, and now we're full-circle back to where we started. Except now the web is drastically different and the browser is now our one and true only terminal to the Holy Server that is Google et al.

Yes they did. They say it twice. I have italicised both places where they say it.

"Let's say there is a terrible disease that 0.01% (1 in 10,000) of the population is infected with, and we develop a test that is 99% accurate. You go to the doctor and get a test. Oh no, it's positive. What are the chances that it's a false positive?

Intuition would tell you 1% since the test is 99% accurate. Intuition, as it often is, is wrong. Take a sample size of 'x', we'll use 10,000. How many people will be infected? 1. How many false positives will there be? 1% * 10,000 = 100"

Then they conclude by saying:

"So there will be 100 false positives, and 1 real positive."

The fact there is one real positive necessarily implies they are assuming the false negative rate is exactly 0, given that the disease prevalence is in 0.01 percent of the population.

It’s a protected class in at least a few states (looks like NY & CA plus DC & PR, with a hilarious exception in CA).

By that logic people now wouldn't use LFP. Demand is huge, and a slightly bigger/heavier battery is totally acceptable if the battery can be cheaper. The reality is it is better to produce more EV even with batteries that are not at peak density specially if they are cheaper.

As I pointed out, Sodium could get reasonably to LFP. So just as we moved from NMC to LFP, we will move from LFP to Sodium. That doesn't mean NMC or LFP will go away.

All of the above are needed.

No one is stopped from having diverse thoughts - you can always think whatever you want.

But why do you think you have the right to publicly & globally tweet it without anyone responding to it? Are you looking solely for supportive replies? And zero debate or criticism?

The irony is that all the people fighting “cancel culture” with their “diverse” thoughts really seem to mainly just have hot-takes that are racist and sexist. Nothing really diverse…
In many cases it was patent issues -- putting the codecs in the OS could significantly increase it's cost.

Two years ago I moved to a house with only a fireplace for heating. I spent the first winter taking care of the fire, which is nice at the beginning but a real chore after a while.

Before this winter I installed a air to air heat pump. The first thing I learned is that everyone calls that differently, to the point that talking with companies to get one installed was difficult: "-Hello, I'd like a heat pump please. -Sorry, we only do AC.". The name people give to this device really depends on the area.

I went with a single console unit, basically a 1x1m square that hangs inside on a wall close to the floor like a radiator. The installation took a day and costs about 2000€.

On the coldest days of the year when the temperature stays around -15°C, the unit uses about 25kWh of energy for a day to heat the whole house at 19°C. About 15kWh on days when the temperature stays around -5°C.

Before next winter I'm planing on having someone check if there are quick wins regarding insulation, I suspect that some of my windows are pretty terrible.

People often complain about the markup on Macs, so it seems reasonable to interpret that as a higher margin being used to compensate for the lack of ongoing revenue. Higher margins are the obvious (only?) alternative to ongoing commission revenue - that obviously puts Apple at a disadvantage compared to

* Google, who makes money by harvesting information from every android user; or

* Samsung, etc who don't pay the cost of developing a platform

* Steam, GoG, etc who literally only operate a store front, yet still take 30% cuts. They don't even have significant proportion of free games - and the games that they do have are frequently > $50 so their per-sale absolute revenue is insane.

* The various console platforms, because somehow consoles are magically different from everyone else

* Microsoft (ignoring consoles) who charges for their OS, and despite that seems hell bent on putting ads into the OS

Late last year we had some major instability with our main microservices as they didn't properly scale and it wasn't pleasant. The backend codebase was Java. In any case 2 months before that we got a dev with good Kotlin experience (he wrote a book on it) and he offered to rewrite those services in Kotlin as that instability was occurring. It took him about 5 days for each (sometimes less). And in a few weeks we had services which were rock solid. Amazing really how sometimes a person who knows his stuff can make a difference.

What your heuristic may be accurate in the general sense, it's absolutely not the case for ImGUIs. I've used the technology on a real commercial product before and it was vastly superior to the old way of doing things.

The "BS" complexity of retained-mode GUIs, as you suggested, is not really BS but the logical result of using a client/server model. That said, for the average desktop application (where all necessary state is local to the user's own machine) this model really is a poor fit and ImGUIs shine.

A lot of the evangelism comes from the fact that many more conservative devs still insist on using the more complex client/server retained-mode paradigm, even when immediate-mode is more suitable to the task at hand.

We are now at a stage where a twitter mob would see "men should not be allowed to compete in women's sports" as a bigoted statement. To the vast majority of people there are important differences between men and women, and will now have to awkwardly self-censors their speech. Or they will worry whether they are actually bigoted and attempt to signal that they are not really a bad person by relenting to the group.

We are also at a stage where a US Supreme Court nominee under questioning was unwilling to hazard a guess at a definition of Woman. The risks for them personally was just too high.

I think you could easily get 10 years into a web dev career and never meet a truly fantastic DB person. Most companies just aren't successful enough to need one.

I am a reformed MySQL user, but one of my overly-normalized MySQL DBs has been running in production for almost 10 years without any optimization of queries, tables, or indices (beyond some naive indices I created when deploying it).

My point is that you can throw an excellent RDBMS onto some decent hardware and serve millions of requests for a CRUD web app without really thinking too hard about it.

At this point, as a Python dev, I wouldn't even bother. The web is dirty and unless you have huge community mindshare or oodles of funding (a-la Google), you're not going to get any meaningful traction with whatever python-based UI framework you create. The JS community (funded by big players like Google and Facebook and 20 million liters of starbucks hipster coffee) has figured out all the tooling, libraries, and practically taken over every facet of the web development ecosystem so it caters for JS, that it's going to be severely impractical and hopeless to jump in at this point.

Decisions Theory (so, statistics and economics) have also always relied on the idea of equivalence (I believe the notion is the set-theoretic one) for purely practical reasons.

So for instance (drawing on the other reply in this thread about Leibnitz), to say that

x = y => f(x) = f(y)

is not really useful when the meaning of the equality is contextual.
If two choices are equal for one person (or prior distribution, utility function, uncertainty aversion etc.), they may not be "equal" if anything changes. And if they are, but other choices are not, the "equality" doesn't help.

By contrast, in if in the moment of where a context is fixed (we look at one potential set of decisions, one choice relation etc.) there exists an equivalence relation, then we can analyze the choice situation with math, and it's the equivalence of choices (with respect to this one relation) that does this. And then, naturally, if we conceive of a situation that we can analyze (or we have data on it), we can conceive the relationships that might have given rise to it.

And, as it turns out, there's typically infinitely many of those. And so, even lowly economists or statisticians must - in some simple way - grapple with what I would imagine categories are (?)

Would love to read more on this. Are there materials on category theory for non-mathematicians (and non-computer scientists thinking in terms of language theory)?

> Despite all the constant hate about electron apps, I've consistently found VS Code to be much snappier to use than any time I've tried using Jetbrains IDEs (whether on beefy desktop or slimmer laptop), and that's even after disabling a huge number of plugins and features that I don't want.

I use both vscose and intellij, and I must say that even though vscode can sometimes feel snappier without any plugin running, it's missing a whole lot of features even with dedicated Microsoft plugins running, to the point it feels half-baked. I'm talking about things like basic refactoring support and even symbol recognition.

IDEs like intellij and Clion may have slightly longer startup times, but that doesn't really matter as you're only going to start the app a few times throughout the day.

Ultimately vscode is nice if all you want to do is open text files and Run regex searches, but the minute you want to run the most basic refactoring steps then it's faster and less frustrating to just start intellij, refactor, save files, and quit the app.
> I always wonder what Bytedance is doing differently compared with other social recommendation tools (aka why does no one rave about Twitter's suggested follows).

The thing is, the engine creates the content. Not quite as efficiently as a human producer saying "I want a 30 second video about X", but through the feedback loop of what gets promoted.

Twitter is run by libertarians who prioritise free speech, and therefore what Twitter produces is more and more intense political argument. Once the Tahrir square revolution and the color revolutions happened, that's what the place is locked into.

Instagram created the "influencer": young hyper conventionally attractive women photographed in beautiful locations, advertising products like energy drinks on their own account rather than a traditional modelling agency structure.

Youtube created the "let's play" and the "thirty to 120 minute political rabbithole" and the "shocked face thumbnail" genres.

Tiktok's secret weapon - and I'm not familiar with how it works in detail, but the effects are very clear - is a video editing tool, a content creation system, that is accessible for ordinary people. The evidence of this is that much of the "reels" content on Instagram's Tiktok clone has Tiktok watermarks on it.
>>could someone please explain what is a left join any why using it exclusively is a problem?
reply

There is nothing wrong with it per se, it depends on the question you are trying to answer - gauging someones competence based on the absolute number of times someone uses a left join, vs right join, vs outer join during their career is silly - almost any query can be written multiple ways to get the exact same results. What matters is did the developer get the correct results.

It's good to have a sense of what other join types do, but if they don't get you to the answer you want any faster or better, so what?
> kotlin annotations (esp. with addition of KSP) provide good mechanism for compile time code generation.

Could you explain this a bit more? I thought kotlin annotations were like Java annotations - additional metadata attached to classes/fields/methods/etc but could not be used by themselves to generate code like a decorator.

Wait. Isn’t “discussion” just another form of “content”? How is it really different?

I thought you might be referring to “other people thoughts” outside your bubble? Which could hint to why you don’t like Instagram (they try to keep you in one thought bubble) compared to HN/Reddit.

PS: I’m actually interested in both, content and discussion. Which is bad because you get addicted to all kind of platforms!
