In the case of the example, there is a move, and std::move works in the example.

The function, show, doesn't take a copy, it takes a Person object. Persons can be copy constructed or move constructed (both constructors are implicit, since there's no user-defined constructors). std::move returns an r-value reference to main's p, so Person's implicit move constructor is called, and show's p argument is move constructed from main's p. The reported address changes because moving creates a new object in C++, but the moved-to object may take ownership of the heap allocated memory and other resources from the moved-from object.

In this case, the moved-to Person takes ownership of the heap allocation from the moved-from Person's string member and sets the moved-from Person's string member to an empty string. Without std::move, show's p is copy constructed, including its string member.

I wrote up a retrospective on my time working as a founder at DirectAI (https://directai.io). We learned a lot and I wanted to share some things I wish I had known ~18 months ago.
You will likely end up with convoluted INSERT OR IGNORE INTO... WITH ...SELECT statement with WITH clause which first detects existing pairwise matching rows and if they are found, the SELECT generates values which purposedly violate some other unique constraint.
If that's practically or philosophically more acceptable to you :)
Oxygen is literally toxic to anaerobes in the clostridia class. Which means their endospores are likely to be where the bacteria is.

Like botulism or bacterial gangrene, tetani can survive for short periods (as can humans sans oxygen) but is unlikely to be found in sufficient quantities to cause concern.
It's not so bad as long as the gears are taken good care of, if this isn't a thing we'll find them defunct in a dumpster yard. There are still positives about having a vintage collector scene, like USB floppy emulator kits, LCD kits, new mods, hacks, sharing old drivers etc.

I’m not American (but live here), and have lived in Europe and traveled most of it.

I lived that era, and don't miss the DX7 at all. Yes, when it came out it was revolutionary and if you wanted to produce very thin sounds, (some) credible organs, really nice electric pianos, punching basses, and metallic sounding instruments that one was the keyboard to use, no doubt, but the drawback was that almost everything else would sound terrible, I mean really awful. Additive synth is great only if done well, and the first DX synthesizer were a lot limited in some fields; if you tried to make a track only using a DX7 it would be a compromise wrapped around other compromises. For starters, operators could generate only sine waves, and every other waveform had to be emulated by frequency modulating an operator by another synced operator; that could be used to make some really interesting effects and sounds, but no way one could produce for example believable strings; they were just terrible. Also it had no filters, that is, no VCF/DCF/whatever, so no way to produce credible sweeps or warm pads that would have been trivial to produce with a 10 years older keyboard.
DX7 has been revolutionary for sure, but had its share of limitations, and (plugins aside, of course) rather than spending money on a vintage DX7, I'd get a smaller and much cheaper FM expander to be driven together in unison with a traditional analog sounding one; the 1st one for the aggressive attack, the 2nd one for more warmth.
As for additive synth, I deeply regret having sold my Kawai K5000 years ago; that was really a beast. Heck, That applies pretty much to all my old gear, but sometimes one is forced to, only to regret much later.
And sometime you really can't do anything except but waiting and letting the potatoes to grow, so to speak ("We plant potatoes in the spring, and harvest them in the autumn" — "Well, we plant potatoes in the morning and harvest them in the evening" — "Wow, do they really grow that fast at yours?" — "No, we just become really hungry by the evening").
The play date doesn’t even have shades of grey and has plenty of good games, arguably because of similar constraints

Just use Firefox.

It is also a better browser.
A bug is generally treated as undefined and undesirable side effects of a program.

Hallucinations are undesirable but not undefined. We know that the process creates them and expect them.

It’d be like using floats to calculate dollars and cents and calling the resulting math a bug - it’s not, you just used the technology wrong.

> If I go visit my grandma over the weekend, my activities do not register on GDP.

Yes they do. How do you visit her? What do you do while you're together? Eat some food? There's almost no way your visit doesn't register on GDP.

In reality, economic growth makes peoples lives better in simple, concrete ways. Ironically, we've started to question this only because we've become so rich due to so much growth that we're no longer dealing with "simple" problems (hunger, cold, etc).
Yes. Why do people have a problem with Nature publishing the occasional 'article' instead of a 'paper'.
The trouble is that if suburbs weren't subsidized, there would be little reason to live there, seeing its residents move further out into more rural areas. The cities are willing to subsidize them as it is net beneficial to the city to have people who won't live in the city proper to still be nearby, improving economic activity in the "downtown" with access to more workers and consumers.
That doesn't really matter if all you're doing is measuring the relative change in GDP though, and the amount of activity that doesn't register on GDP isn't increasing.

In other words, if you assume non-GDP activity is constant, then GDP does genuinely and accurately reflect economic growth.

Indeed, this is one reason why economists recommend GDP as a useful measure of growth in a country year-over-year, but not for comparing different countries' GDP directly -- the ratio of activity not counted as GDP may be quite different between countries.

Now, if you think that a massive social transformation is underway of non-GDP-registering activities to GDP-registering activities -- e.g. people used to care for their grandmas, now all those people have gotten jobs to pay for care assistants to do it instead -- then yes GDP will show "false growth" in productivity.

But that really doesn't seem to be a major factor. We really are seeing massive amounts of innovation in the economy that improve people's lives. Economists don't just look at GDP -- they look at lots of measures that all tell the same story. Productivity really is going up. GDP growth may not be 100.00% accurate, but it is mostly.
You should hear about the movement to take the word 'gullible' out of the dictionary.

You don't actually know that, because you keep missing the point. How do you know I'm wrong if you can't seem to grasp what I'm talking about?

I don't think you're as clever as you seem to think you are. Maybe you should consider the possibility that the advice I gave up-thread is literally true in your case, and not just a reminder to take a position of humility.

Oh damn that sucks, still nothing affecting user experience... yet. Reminds me of a nightly build I saw where they tested forcibly putting fakespot products on the frontpage.

I think they knew this was gonna be controversial, you'd think the blog title would mention something like this but they choose to focus on smaller bug fixes and tuck the literal forced advertising near the bottom. For now I'll stick around, but if this stuff ever gets released / impacts the way the browser functions I'll have to find something else.
I actually find the contrasting approaches (see discussion elsethread about the terminology used in the diagram) helpful and it's always good to have historical context.

> Starting from secular first principles, what’s the argument that people shouldn’t be happy a wealthy CEO of a company that people perceive does a lot of harm

This should not exist. We have government to look after the people, why do you have a CEO in this position in the first place?

If a medical professional determines that the person needs attention, then the company should not deny it. It has been deemed necessary by medical professional. Secular is not the same as "always generating money", and if this is not a money making business them it should be covered by cooperatives.

But that only would need to happen if your government is far too corrupt to do the correct thing and look after its people.
Few things I despise more than an absolute number provided with no context. Is 60K a lot? A little? The usual? How much does it deviate from the norm?

If we had more insurance companies instead of a few that dominate the market, then your employer would have more choices. More competing insurance cos would lead some to differentiate by having a reputation of honest claim handling while also not being the most expensive option. It would then at least be possible for an employer to choose better insurance companies.
> The maximum for a pure analog polysynth was 8 notes, and cheaper models had between four and six notes. No fancy jazz chords. Especially not with sustain.

Some had total polyphony though, by using divide down oscillators.

> The DX7 stood out because the keyboard responded to velocity, and it had an incredible 16 notes of polyphony. So you could play your fancy jazz chords on the epiano sound with the sustain pedal down, and the notes would respond to your fingers and wouldn't cut off too obviously.

The dx7 was capable of making sounds that were simply impossible to create with regular analogue subtractive synthesis, because FM (phase modulation in practice) allowed drastic tonal changes in a timbre "through time". So the attack of a patch could have a completely different "waveform" than its release, thanks to operator interaction. That's what the true novelty, a realism no analogue synth could achieve.

A kalman filter does what, in this case? Pardon my ignorance, but I have only seen that used for estimating locations / parameters of some process or target, not for determining existence ("is N>0?") or amounts ("what is N?").

You could cobble together a quantity estimation doing some kind of batch data association with noisy "presence" measurements, but you're probably not much better off than k-means at that point and any KF-based measurement will basically just say "Yes N>=1" because the probability is nonzero.
Incorrect, but you’re changing the subject. Help me work through how secular morality handles the assassination of a CEO of a widely hated company.
At the same time Nix implements python packaging particularly bad[1] when it does not have to. And that's on top of already insane state of python packaging. And poetry2nix becoming deprecated really bit me recently :/

Similar issues (minus insane packaging) is with Common Lisp packages, where there's annoying focus on compiling libraries into binaries (it would have been fine to have a bit of patching to provide things like correct paths for ASDF and CFFI search paths, but no....) which gives absolutely no benefit.

The most meaningful definition of intelligence is one that captures the essence/nature of human/animal intelligence, which is where the word originated.

I think you can get to the core of it by considering the evolutionary benefit of intelligence - what beneficial behavioral capability has been optimized - which comes down to being able to utilize past experience to predict/plan future outcomes, rather than being locked into reactive behavior patterns like simpler animals.

LLMs, trained to predict based on past "experience", might (perhaps charitably) be considered to exhibit some intelligence, but where they notably fail is in situations where better prediction (utilization of prior experience) requires a process more similar to search with backtracking than a linear application of rules derived from the training data - i.e. in the areas of reasoning and planning.

You can try to put lipstick on the pig by adding RL-based post-training or wrapping the LLM in an agentic loop, trying to extract more value out of the training data and gain some semblance of reasoning, but at the end of the day it's still a pig - at heart just an expert system not a cognitive architecture.

Another obvious limitation of LLMs is that they are just a repository of canned knowledge/rules, with no ability to learn from "runtime" experience, and therefore lacking the ability to learn to handle novel problems by experimentation and adaptation to failure.

The limited intelligence of LLMs is firmly baked into their architecture - the transformer, being just as pass-thru model, as well as the way they are trained by SGD rather than an algorithm capable of continuous incremental learning.
I use Firefox as my main browser on a Mac. A lot, every day - I have about 30 Firefox windows open now. But there are a number of things that only work in Chrome or Safari.

So I also use Ungoogled Chromium. I have about 3 Ungoogled Chromium windows open now.

Occasionally a banking, financial service, shopping or video meeting site doesn't work right in Firefox. I've had some site logins just spin forever in Firefox, and work immediately in Chromiun.

For example, for work with one company we use Google video meetings a lot. In theory this works in Firefox, but in practice sometimes the audio doesn't work. The microphone volume gets set to zero, unpredictably. It's flaky enough that I switched to Ungoogled Chromium for those, and decided to use it for all the Google Workspace linked services for that company, as well as AWS, Hetzner etc accounts linked with that company.

Chromium's profiles are good, with clear separation and a reasonable UI. So are Firefox containers, but in different ways.

Firefox automatic per-site container selection doesn't work at all well when you have multiple accounts on the same site, though. It doesn't group container-switching according to working context. So I have a couple of Ungoogled Chromium profiles for work with different companies.

Finally, Chrome renders print-to-PDF better for some use-cases, so I use Ungoogled Chromium to generate invoices and similar documents. Firefox print-to-PDF works, but I could never get ruled lines to be.a good thickness on the printed page. They were always too thick, or invisible. Firefox did better pagination last time tried it, though.
Probably one of the best, must humorous, and dark takes on industrial psychology I've seen. I've spent a lot of time trying to disprove it, and kinda did.

It's like Freud where it doesn't really stand up to serious empirical evaluation, yet there are so many uncomfortable truths.

The author kinda loses the plot after the part about power talk, though.

The Opsix looks very straightforward. I bought the Digitone Keys about three years ago and it's a lot of fun, along with having that sequencer and Elektron Interface. It does not appear to have been a successful product, and I do not think it's really possible to use a full instrument, but I have enjoyed using it as a plaything to learn and understand FM synthesis. No doubt there is some creative wizard like Blue Lab Beats who probably uses this and a Digitakt to make whole albums.
I’m sure China/Russia/Israel/India/Saudi Arabia/Iran/North Korea/Pakistan/etc are all doing exactly what the US wants.

The US is so effective that it can force a country that it embargoes (Iran) to sell oil in USD to a country with its own currency (India).

https://www.economist.com/finance-and-economics/2024/10/17/i...

And the US allows articles to be written about China and Saudi Arabia considering buying and selling oil in Yuan, ostensibly to provide cover for the fact that the US is actually forcing both China to buy in USD and Saudi Arabia to sell in USD.

https://www.wsj.com/articles/saudi-arabia-considers-acceptin...

It couldn’t possibly be that Iran trusts USD to have a more reliable purchasing power than an Indian Rupee, or that Saudi Arabia would rather bet on stability from USD rather than the Yuan.
That statistic is defined as “urban” vs “rural”. By that definition, all American suburbs are counted as cities/urban areas. So the statistic doesn’t disprove their assertion.

Related to that, I once had a CT scan for a potentially fatal brain concern, and the note that the radiologist sent back to my consultant was for a completely different patient, and the notes for my scan were attached to someone else's report. The only reason it was caught was because it referred to me as "she".

If we were both the same gender, I probably would have had my skull opened up for no reason, and she would have been discharged and later died.
Most egregious thing is many times when people roll their own forms they end up actually removing things. The amount of forms I encounter where autofill and spellcheck are broken is crazy.

Maybe it’s some “best practice” library popular in the react ecosystem, I see it often enough to suspect that but autofill and spellcheck are my input and my business and a form shouldn’t decide if they’re enabled.
