> But the somewhat random nature of how weekends and certain holidays are distributed throughout the calendar can have effects on business, and presumably other areas.

Yes, and? Isn't it to be expected? Calendars are long-living standards, that adjust over long periods of time, because of the practical impact they have on societies.

Why should those commons adjust themselves in order to satisfy self-imposed, often antisocial business requirements? (how MoM revenue performance is calculated and rewarded is strictly a concern for said businesses).

If it should contribute to an underperforming year for your company, it would be a way lesser factor than the lack of preparation or perspective from its owners/executives, because the calendar-related discrepancies are already known in advance (and it's not a particularly recent phenomenon either).

Would even such a deciyear (or any other new) calendar be adopted, it would "diverge" again in the next 10/20 years by the simple sheer force of society cultural evolution: "we will have more bank days here", "we need more working days there", "ho, we need to mark this particular date because of this event", "ho, these partner countries follow a new tradition, we need to adjust somehow".

Ok. Perhaps a new calendaring system could make sense for businesses. The only way forward would be for businesses first to design and adopt it, in parallel with the public calendar system, and show how it works better. Would there be a favorable business case? Especially in relation with financial and regulatory requirements which are still based on civil years? (and even different across countries)
You can only have decent sound with small speakers if you don't care about bass. Intentionally adding bass distortion to trick unsophisticated listeners into thinking there's more bass than there really is won't fool anybody who's familiar with the real thing. As Hofmann's Iron Law of speaker design says: deep bass, small size, high efficiency -- pick at most two. And there's only so much you can compromise efficiency before you melt the voice coils.
They're aiming to hit net zero before 2060. It's.... ambitious (which I use here as a synonym for unlikely). USA and EU are aiming for 2050.

Will anybody meet their goals? The planet is the ultimate Commons. Personally, I think we're boned.
Ok? Not sure what you want to talk about here, you probably need to give us a bit more context, especially if you even acknowledge you haven't even opened up the article to talk about the submission itself...

Sometimes, the situation when something gets created and designed, looks very different from the current situation you're in N years later. So what might have looked like a boneheaded decision, could have been the best decision at that point.

But us engineers like to lament our predecessors' code, I'm guilty of this sometimes too. But I try to remember that I don't have the full context of how things were when the code was initially written.
Imagine reducing the fiber, sugar, water, minerals, and "everything" else in some apple slices by half. You haven't made it less nutrient-dense; you've eliminated everything that makes it up; i.e., you've just made it smaller.

The researchers aren't arguing that we eat less. They've defined some things as important "nutrients" in some sense and noted that the relative (not absolute) concentrations of those have decreased.

Whether that matters for a particular application is up for debate. Certainly macronutrients matter. It's really not hard to understand what they mean though.

Partially, you need to rely on the community for GUI stuff (Avalonia and Uno), and old Microsoft still pushes VS/Windows as the best experience, anyone else that wants a VS like experience has to buy Rider.

Yes, there is VS Code, which besides being Electron based, Microsoft is quite open that will never achieve feature parity with VS.
Not OP, but I’ve encountered this in situations where legacy code involved in mission critical business functionality was nearly impossible to remove due to the potential risk of unforeseen impact.

In other words, if the potential impact of an unforeseen breakage is high enough (costs us or the customer $$$), it’s not worth risking the change even if we can find absolutely no good reason for the current behavior to exist.

Example: complex spaghetti that touches billing calculations. These things are better addressed by a full rewrite/redesign followed by a long period of running both things in parallel until we’re confident that we didn’t miss anything. Maybe this is just a more complex way of removing the fence, but I think it’s more like moving away from the ground the fence is built on.
I love change in general, but when I hear talk about architecting society I get mental images of mass graves. I just made a post advocating climate engineering in addition to net neutral carbon, but the potential unintended consequences of planet scale climate fiddling scare me far less than trying to plan societal changes that will counter human nature even just a bit.
> even if application level consistency constraints are violated.

I think, in theory at least, it should be possible to encode the application level constrains into the CRDT merging algorithm. Like how two edits making different (but overlapping) spans bold are fine to merge into one bold span, but i.e highlighting with different colors are not.

Of course the merge will never be "perfect", as it is impossible to encode all human wishes into the CRDT, but I think there is a lot of room to improve when it comes to merging non-text data.
Very insightful. IMO this is exactly what leads to many engineering teams to want to re-write a system from the ground up instead of trying to fix existing systems. They underestimate the complexity and assume the problems with the current system were the result of poor skill quality, rather than confronting complexity and nuance that they also aren't expecting. So they promise a rewrite in a couple months, a couple months turns into 6, they get pressure from management to wrap it up and ship the new thing, so they rush and they do. Then that system sits there for a couple years until a new batch of engineers comes and argues that the system sucks and the answer is a rewrite from the ground up. Rinse and repeat.

In what way could this question be asked in bad faith?

I've done ssh over websocket before (to bypass a corp proxy)... been thinking about it a lot lately. I would love if mosh got support for different transports than just udp and it would be cool if the initial handshake could be done over http instead of ssh.
You occasionally see remasters going against the trend and increasing dynamic range. Earache Records has several high dynamic range versions of classic metal albums on Bandcamp.
It seems like you have no idea how much effort it takes to write a book.

Quite often it contains the experience of a life of a person condensed to a few hundred pages.

ChatGPT gives easier access to the knowledge contained in tens of thousands of these books. As for me I have been reading less and less books as more wisdom is accessable on the internet in better forms (now GPT).

I'm not against what OpenAI is doing as it moves humanity forward, but like you said I won't stop using ChatGPT just because ByteDance scrapes it.
That's ridiculous. My trip was from Ottawa Canada to Saskatoon. It goes through some seriously unpopulated territory, unlike yours. It does follow major highways, so there are Tesla superchargers along the route every 100-150 km or so. We'd stay at a hotel with charging overnight so start at 100%, drive for 2.5 hours and then bathroom/charge for 15-20 mins, drive another 2.5 and eat/charge for 40 or so, repeat the morning pattern in the afternoon, and then drive for another couple after supper before stopping at a hotel to charge while sleeping.
I like this format for displaying these temporal changes. I have rainfall data for my location that I have tracked for more than 20 years and it currently lives in an Excel spreadsheet. I have a few graphs but these annual difference and monthly deviations from normal will enhance what I already show. I like the format.

I am merging my rainfall data with ENSO data about El Nino and La Nina years to look for patterns in local rainfall during those periods. We are currently in an El Nino and it is predicted to be strong. If it doesn't rain again before the end of the year this will be the second driest year in more than 20 since I began recording rainfall and I am currently >13 inches (>330 mm) under normal for this date. We finished last year in a similar condition, 12.6" (320 mm) under normal. Based on our long-term (10-day) forecast I expect this to be the third or fourth driest year since I began measuring. North Texas, west of Fort Worth.
I also read into vitamins and minerals (while trying to ignore all the snake oil), and I agree with you!

I tried a lot and the ones I keep buying are the same you do - Magnesium, Omega-3, D3+K2 and a B complex. These are not only the ones that most people are likely to be deficient in, these were also the ones that I subjectively felt had a positive effect on me, and either low or deficient levels were confirmed by blood tests. I feel a lot better, too! :)

Regarding the magnesium: I did not know that. How do you make sure the brand and/or it's magnesium is of good quality?

It's curious you say this, I wasn't totally sure, but I sometimes felt like there was a difference in quality, even between the same brand or product of the same form of Magnesium.
The actual speakers haven’t changed much, although I suspect many are increasingly designed around the availability of good DSP.

But the good amps are all over. Look at any site with actual data. For example, this thing is definitely cheap:

https://www.audiosciencereview.com/forum/index.php?threads/e...

Some of what’s going on is that TI and others are making very good class D amplifiers on a chip, and they’re fairly easy to integrate. Several companies (IMO sadly mostly Chinese) are selling integrated DSPs and amps that are fantastic and cost a couple hundred dollars. They probably outperform multiple thousands of dollars of gear from 30 years ago, and they are far smaller and generate much much less heat.

I bought B1 much cheaper in powder, but no idea where... some site for bodybuilders's supplements. That Aavalabs complex is also good. Magnesium is from the same brand as Omega-3, Zenement. The D3+K2 is from GloryFeel.

They build premium speakers with a WAF (Wife Acceptance Factor) that's so far off the charts, they're no longer an electronics company.

Their speakers are so beautiful, it's almost better to think of them as a luxury furniture or interior design company.

I think it's absolutely the right business decision for them to lean into this unfair status, and try to make their products Veblan goods like the luxury fashion houses already have.

I have used logback for almost 15 years now instead of log4j.

util logging and commons logging weren't nearly as good, although I don't recall specifically why. jdk logging was fine-finer-finest and some other weird things

Ultimately what is important in javaland is adopting SLF4J and then delegating to whatever you want to use beyond that for the actual logging.

In Aws, you can pay for "premium support" and get help from them for issues like this. Can even pay, get help and then cancel the sub, it's like $50 for the month.

Maybe azure has an equivalent.

Actually event driven stuff is highly consistent. Event insertion is fast as hell and all of it is timestamped and tagged with a unique Id so there's no consistency issues.

The problem is availability. You have to aggregate those events to get anything meaningful about it and aggregation can be really really slow.
I manage a highly complex AI service, and from time to time make config changes, and part of that duty is config cleanup -- removal and simplification. This is a necessary job in the past I have found copy-pasta where settings overrides for one environment are incorrectly copied to a similar one, leading to bad customer experience. As a personal policy, before submitting the cleanup PR, I go back in git history to when the config was introduced to understand why it was done the way it was, in case I am missing something. I call this "paying the Chesterton Tax."

Usually its fine, though once in a while the original author gets annoyed at second guessing their work long after it was considered settled. One recent curious example was when I found a specific setting was applied for one out of a set of many similar subservices; when asking around for why only one of them got it when the current data suggested all subservices would benefit, a senior "architect" got annoyed with me asking questions. As best I can tell: the project was shelved after a few months when the architect solved the primary issue and got bored with it / delegated the polishing touches to a junior engineer who went on maternity leave shortly after. Which is a fine enough explanation for me to proceed, but nobody's eager to admit such social causes.
summary: improve prediction of run-time performance of a computation graph using GNN, they use an embedding dictionary for each node's opcode along with some other node features (eg shape, bits, window size, see [1]), they released a big dataset of these graphs in [2] with varying XLA compilation configurations and their resulting perf on TPUs, they did some stuff to improve prediction on bigger graphs than before in [3] by partitioning the graph (METIS graph partition, new to me) and other training things

This is only about predicting performance of a given graph and not about improving/suggesting/editing a new equivalent graph. As in FunSearch, models which have decent predictive power could be used with evolutionary search.

I don't think you understand Chesterton's point. It's not that hard to see it is valuable to know why things were built.

It's the same reason we study history, to know what came before us so that we can make good decisions going forward.

There do exist people (even on the internet) who ask similar questions about climate change, who prefer to attribute it to all kind of other causes, and deviate or deny that human activities create climate change. I do know that wasn't part of the question, so I can only guess and hope.

meta I love the fascination with the Fourier transform on this site even though I would venture most of us haven't thought of it since college if even exposed to it at all then. My hunch is that it's the first math concept many of us encountered that's not straightforward. Even integrating and taking derivatives is mostly procedural and intuitive. Plus it's so insanely cool when you understand the power of changing domains. I'm no expert, I'm a failed EE turned mediocre programmer, but I'm equally always in awe of it. Its history is so fascinating, especially how the FFT came up - I saw a great Veritasium video on it.
It has one. It's called a 1 pound coin, but wait a few days and it will be worth 99p.
The crucial aspect here is “yet.” Most car makers are on their very first foray into EV, but have been perfecting efficiencies in ICE for many decades. The summary judgement articles and whatnot declaring EV dead on arrival ignore that ICE marginal improvements are slow and expensive, while EV marginal improvements are fast and cheap. How long until EV are cheaper and more reliable? I’ll wager in the span of 5 years. Then over the equivalent span of ICE dominance EV will continue to improve to a platform that will make ICE look like horse buggies.

> If something reads 98.2 one year and the prior reading is 97.3 we have a 0.9 increase in temperature, but in reality it could be the margin of error based on cloud cover or a change in instrumentation.

That would be true if we had only two measurements. But it can't explain the trend over the last 40 years (neither can the introduction of digital thermometers in the 60s).
> The purchase of a Rolex or Ferrari - or an incredibly overpriced sound system - is an attempt to buy a signal to others that you have taste. In fact you’re signaling how much your lack of taste is costing you.

Emphasis on _usually_. If your db is at 2% CPU utilization with/without queues ... you probably don't need a queue.
Oh this is a gold mine for me. Recently I’ve wondered how games architect card game rules. So many rules feel kind of bespoke, so I wasn’t sure if you could implement a sort of logic so that rules become configuration, or if each rule is just a function.
I don't understand the math, but the ability to rotate the time/frequency of a sample of data to filter out chirps and things like that via DSP sounds damned handy in some cases.

I started learning DSP playing around with audio signals in GNU Radio. Filtering gets a lot easier if you have IQ signals, so you can shift the frequencies up or down below zero, and back up. There are types of filtering you can do that way, that just won't work with only REAL signals.

This is another powerful tool for that toolbox. Thanks!
