My argument is that eating vegetarian does not reduce land use for agriculture.

It does to first order. Then we just end up with more mouths - like what happened after the Haber-Bosch process.
Can you directly cast an object / assoc array to an instance of such a class?

If I have a function that receives eg a Message, it means an instance of the class right? So somehow my assoc.array/object still needs to be instanced, and if I do just $message = new Message($theData) … it doesn’t auto assign properties right? That would be handy though still very much boilerplate.

I guessthe language is just designed for how it’s been used so far, may e it will change if JIT makes php more open ended in its uses.
I was expecting this to happen because the proof that the limit at zero of (e^h - 1)/h = 1 is tricky — nope, the student doesn't recognize the derivative formula in the first place.
Gosh that's a fun read in all sorts of ways. SSDs are relatively new, there are hold-outs, and they cost $300 for 80GB!
Abit was around for quite a while after. I had a Core 2 Quad with an Abit motherboard.
Now that most of Apple's top talents from its CPU division have left for greener pastures (1), I guess this is their new strategy - somehow delay their competitors from launching new and better chips while Apple scrambles to find new talents in the limited pool available. Apple has bet their future on Apple Silicon, and it badly needs to retain a lead on other competing CPU for a year or two, to capture sufficient market share (the perception of Apple Silicon leading over other CPUs is very important for this).

TSMC also seems to be taking a big gamble, pissing of existing good clients.

I think that's the direction it's going. NFTs are a revolution for digital artists tho - as they allow for a global liquid marketplace that enforces automatic royalties. That's the power of smart contracts - suddenly I can make digital art that automatically reverts profit from subsequent sales to me - 10% or so at least.

The example was hilarious to read, and definitely a great feat to implement such a complex algorithm. I wonder why was Erlang picked and whether it will be offered as a service.

Also how does it know how to replace "correct" by "misspelled"? is it maybe a list of synonims with stadistic correlation based on the semantic domain?
Where are you seeing $60/mo? The pricing page shows $11/mo for an individual (or $9/mo for annual) or $47/mo for a team of up to 10 (or $39/mo for annual).

Prompted by the Thanksgiving thread, I realized how thankful I am for HN. I wouldn't be where I am without you all finding & sharing my open source projects.

All of you here made my career possible and thus changed my life in ways I could never have imagined. I'm forever indebted to this fantastic community.

Thank you from the bottom of my heart.
The first link jumps to mathplanet when I select English for the site. I tried searching, but couldn't find a similar article there.

The second link appears to be a curriculum by grade. I'll try again later, thanks!
Happy Thanksgiving day family.
I love you all here.
May the gods of tech be with you all.
As a JS dev it’s nice to see php imitate some newer js syntax like nullish coalescing, arrow function, … helps me to switch between the languages.

It really needs a way to declare type of small data structures though, in a very concise way (no class boilerplate, for performance eg. going through 10000’s of entities).

PS : on the other hand I’m starting to dislike how languages become "designed by committee", and lose the purity of the original design.( thinking of JS mostly here with its gazillion rfcs)
I think that this is indeed the formula in GP's question. And indeed sometimes math notation is obtuse like that. It looks like 2 terms, but the triangle goes together with the t as a single term. At other times it might be called "dt" and despite looking like a multiplication of 2 variables (d and t, or triangle and t in this case) it's just a single variable with a named made of 2 characters.

The important thing here is that "For a pulse of width Dt" is the definition of this variable, but this can be easily missed if you're not used to this naming convention.
Thanks for testinfra, awesome link. Integration with Jenkins and/or Nagios makes this super useful for remediation.
What you're looking at is calculus, specifically differentiation. This is pretty core to understanding physics, because so much of physics depends on the time-evolving state of things. That's fundamentally what's happening here.

The triangle, for example, is the upper-case greek letter delta, which in calculus represents 'change of'. You might have heard of 'delta-T' with respect to 'change of time'.

In calculus, upper-case delta means 'change over a finite time' vs lower-case delta meaning 'instantaneous change'. The practical upshot, for example, is that the lower-case is the instantaneous rate-of-change at an instant in time, whereas the upper-case is the change over a whole time (e.g. the average rate of change per second for time = 0 seconds to time = 3 seconds).

If you are trying to grok this, I would suggest an introductory calculus or pre-calculus resource. It doesn't have to be a uni textbook - higher-level high school maths usually teaches this. In this particular case, the Khan Academy would be my recommendation because it is about the right level (we're not talking esoteric higher-level university knowledge here) and it is eminently accessable. For example, this link may be a good starter in this instance:

Buy them the beverage of their choice and figure out what happened (and if you’re next in X years) let them know the pickle you’re in (and that you don’t blame them of course), and ask for some tips if they are willing to give you some.

You worked together, surely there was some rapport there?
Idk feels pretty arbitrary to say the Fourier expansion of a function matters more than any other expression of the function when the whole point of the Fourier transformation is precisely its ability to express any function in terms of an orthonormal set of functions.
That was delightful! I never knew there was so much variety in Occlupanids. Someone should extend that system to plugs and sockets.
"Anything too stupid to be said is sung." - Voltaire (supposedly)
We weren't cloud-based; "bare-metal restore" would have meant acquiring and housing new hardware. And we'd have needed test-scripts and so on - more than 8 hours, more like a few days to do it repeatably (but once that was done, it could have been automated).

The boss owned the company; I think it was shortsighted of him. Being able to blame me wouldn't have done him much good, once his firm had gone down the tubes, and I'd moved on. But it was his business to lose, and he knew what his margins were - I didn't.

He didn't like me much, mainly because he was a control freak, and I knew his systems much better than he did - I had the control that he craved. Control freaks shouldn't hire people that know more than they do.
Nah. It's cause they human and just pick round numbers, 10, 20, 50, 100.
> I’m under the impression that London’s tech market isn’t particularly hot apart from finance.

This is because FAANG refuse to benchmark against finance, because it would cost them too much money. Like they wanted me to move from Dublin to London when I was at one, but the salaries were identical, but the living costs definitely were not (salaries were the same, but a FAANG salary in Dub puts you much closer to the top of the local income distribution than one does in London).
The best is that Agile avoids the pitfalls of trying to make and update a conventional schedule analysis, i.e. a resource-leveled critical path analysis of a software project. By deferring task assignments to the start of each iteration, you avoid frequent replanning. In other words, Agile is a practical approach for software development projects. It fits the nature of unique and hard to predict task durations.

The worst is when an expediently trained "Scrum Master" with no domain expertise in coding, but equipped with a fully loaded jargon vocabulary tries to "manage" a team of coders.

I actually wondered why the industrial revolution didn't happen in China, great to see one possible explanation menioned in the article [1].

Does anybody know other theories about this?

> Winner was just 25 years old when she printed a single classified document — one that described Russian military efforts to spear-phish dozens of local election officials ahead of the 2016 election — smuggled it out of the NSA facility where she worked and mailed it to The Intercept.

> While attempting to verify its authenticity with the NSA, an Intercept reporter inadvertently revealed its provenance. According to an FBI affidavit, the document had a telltale crease in it, indicating it had been printed and folded. An FBI agent assigned to the case would later testify that a total of six people had printed the document. The pool of potential leakers was further narrowed to one — Winner — when investigators discovered she’d emailed The Intercept from her work computer.

Lessons:

1) Don't leak out information to potentially incompetent people.

2) Don't email potential leakees from your work computer if you work for the NSA.
Sorry I didn't mean to make you work for me, but it's a PDF and I didn't know how to explain better the position (maybe I should have told you the first formula on page X).

For you it was a D, for me it was a triangle and I didn't get the meaning of that Dt. Maybe it's just a too advanced paper for my knowledge.
I’m actually surprised that nobody has been caught using Amazon or Walmart to sell drugs. Package up some sort of expensive “soap flakes” or overpriced oregano.
Everything about NFTs is irritating. They're pure positional goods, with no real utility beyond signaling social status. They're subject to intense, irrational financial speculation. They attract insiders, hypesters, and scam artists. Their fans are prone to wildly overstating their capabilities and importance. The pieces of art they point to very often demonstrate almost no technical skill. They're built on technology with objectively terrible performance characteristics.

But I've thought Facebook was stupid since 2004. Experience has taught me that I'm a weirdo and my aesthetic objections are usually anti-correlated with a project's success. I am the George Costanza of social media. If you're reading about Non-Fungible Tokens on Hacker News, I suspect you are too. These things are here to stay.
As long as there’s an easy way for the user to choose a different language and currency, it seems defaulting based on location would be correct for the highest percentage of users, unless you have some reason to believe it’s more likely that your audience is, say, English-speaking users who prefer to see prices in USD.
Ebay sells out of popular toy that swears and sings in Polish about doing cocaine

"This year's hit toy was late in coming, and the few remaining are going fast, some for incredible prices."

I've never heard of Cypis, and now I absolutely want this toy. Learning to swear in Polish is a form of education. The happy accidents coming from Asian production can be really awesome. There are lots of negatives from this kind of production; we should be happy for the few positive ones. This is almost as great as getting a Barbie Liberation Army GI Joe or Barbie.

(UK here) I have had a Loewe for about two years now. I hadn't heard of them myself but came across them when buying a Linn [0] audio system - the audio shop I went to offered Loewe as one of the options for an integrated sound+vision package. My overall system uses Linn as the sound output for the TV instead of a Loewe sound bar.

The TV is fairly excellent and the hosted apps are fine and not in your face - the TV comes on directly showing its current input (e.g. in my case from a BT smart box) rather than apps or a start screen or similar. I can also immediately cast media to it by a right click from my PC.

I initially had problems with the overall system integration: I have poor wifi coverage in my house and the TV (Loewe) and sound systems (Linn) wouldn't always work reliably together until I had ethernet wired into my house. Also, and this is not a big problem for me, an Alexa can recognise the Loeve as a device but appears unable to use it for sound output. In the bin for you, Alexa.

Just want to say, good luck OP. I was in your position about 3 years ago, though with a smaller company at the time. It was the hardest, most stressful experience in my career so far but I've come out the other side with immeasurably greater confidence and skills. This will be the most brutal learning experience of your life. But, if you need to throw in the towel, there's no shame in that at all.
>In an open economy, the money is printed from the public demand. The more demand, the more printing, the more inflation...

Not really? Most developed countries have a central bank that "prints" money by doing interest rate changes, which in turn is determined by inflation rate targets.
I really like that list!

Thanks!
Lots of questions here.

How many of buyers pay for the "access to the community" and how many are speculators that just want to sell them later?
Lots of speculators for sure.

will they keep supporting artists when they realize that they can't make a profit anymore?
90% will leave. Speculation is a part of any market tho, including the art market. Look no further than the Mad Men episode where the agency owner bought a Rothko "because the price will double in 6 months".

"Peak of inflated expectations"
Yes. This seems like a good description.

I think as a concept they might stay and find some use.
Every concept of how to make NFTs more useful is actively being worked on. So yes they will stay/become more useful.

> The particular topics he wanted me to cover were integrating log x, or ln x as he called it

What's wrong with calling it ln x? The way this is written in the article implies there's something weird about calling it that. The name 'log' can mean log2, log10 or natural logarithm depending on the field.

Removing ambiguities from math notation should be considered a good thing.

The author expressed a worry about math education. Consider that a clear non ambiguous notation would help.
School, one year after another. Delta t stuff were probably in the last year before college.
Why is chemical dependence bad? Countless people are highly dependent on caffeine for example.

I can see perhaps if it isn't managed and doses escalate out of control, that's when off target effects really take over. How about running out of the substance and needing to go through withdrawal (readaptation)?

Perhaps tolerance escalates too quickly and you lose the beneficial effects?

All of these things can be managed by coming up with a dosing plan to maintain concentrations in the therapeutic window, using easily obtainable substances, and cycling on and off of the compound to maintain the beneficial behavioral and psychological benefits.
Forced Entrepreneurs (Journal of Finance)
I think its not fair to put the Elbphilharmonie in the same category.

The original plan looked very different from what was later realized. Which was a significant driver of the cost.

Just for fun, lets compare it to the Sydney opera house:

Elbphilharmonie, original projected cost: 186 Mio EUR

Elbphilharmonie, final cost: 866 Mio EUR

So in the end, 4.65x the projected cost and 7 years late.

Sydney Opera house, original projected cost (inflation adjusted cost in parens): 7 Mio AUD (70 Mio EUR)

Sydney Opera house, final cost: 102 Mio AUD (632 Mio EUR)

So in the end: 9-14x the projected cost and 10 years late (depending on if you compare based on the inflation adjusted costs).

Therefore, in comparison, not that dissimilar.
Wow thank you, _this_ is what I've been looking for!

That is some weird alt-history. In San Francisco, before Uber, this was the situation of the taxi industry:

- It was routinely a 2-3 hour wait to get a cab on Friday or Saturday night

- Rampant discrimination by cabbies who would always ask you where you are going and would refuse to take you if they didn't like the answer. They would frequently refuse to pick up black passengers (pretending they didn't see you on the street). Very few cabs had disability support.

- Cabs were old, in poor condition, sometimes dirty. Sometimes they were also new and nice, but there was no quality control.

- Significant problems with cabbies yelling at passengers, not bathing, smoking in their cabs, and generally being surly.

- Cabbies were under-insured and also poor background checks.

- Side payments to the dispatcher and other bribes were common to get the high paying airport jobs

- cab rides cost about 40% more than now

- The city made hundreds of thousands per medallion as they auctioned off the right to be a cab and artificially restricted supply.

- There was no opportunity for part time cabbies -- you needed to pick a shift and then drive that shift. You could not set your own hours. This created a situation where there weren't enough cars on weekends because the number of medallions were fixed.

- Cab companies earned insane profit margins - 50% margins was not unusual for Yellow.

Basically all of the above issues were substantially improved by Uber and Lyft. You can get a ride anytime with 10 minutes of waiting or less, and you (usually) pay less. Lyft is a bit in between Uber and regular taxis in that it is usually more expensive but does not have the same surge spikes, trading off wait time for prices. The system of rating cabbies gets rid of those who smoke in the cab or don't shower, or don't keep the car clean. Just a massive increase in driver professionalism and politeness.

Uber and Lyft were one of the few ways that blacks and minorities could regularly get rides as the platform did not allow discrimination. The platform also checked the routes to limit the number of riders being ripped off. Uber also has dedicated disability rides that you can select from. And for the drivers, you can now work any hours that you want, you do not need to pay a gate and so risk is reduced.

Just an overwhelmingly positive improvement that significantly increased quality of life for san francisco riders and opened up new income earning opportunities to those who were locked out of the medallion system.
Right there with you… but these types of observations seem to hold in crypto vs fiat currency, no? I feel that’s the vibe the op is getting at.
EU Proposes 9-Month Limit on Covid Vaccine Validity for Travel
The issue is backups.

We're a B2B/Enterprise SaaS and most tenants require that we erase all their data at the end of the contract. Some require customer-managed encryption keys. The only way to meet this requirement is to have every tenant isolated in their own database (and their own S3 bucket etc). If data is mixed, when one tenant leaves you must go through all copies of all backups, purge their rows, then re-save the cleaned up backups. Nearly impossible in practice.
Because this thing looks like it could fill the same need as ProRes while being simpler and open source. For the applications are you are talking about, the format cannot be ruined because it is an internal implementation detail, in the same way that the stb_* libraries can never be ruined. They are yours and everyone's for forever.

The GPs advice about recording color space is spot on. Why design a new container when there are tons of ones off the shelf ones. The collection of files inside a Zip is my goto.
Yes? Do you suppose I can go wherever I want, and do whatever I want whenever I want to?

I'm a cog in a complex socioeconomic system. What I can and cannot do is limited by that system.

If I want to get into let's say making music, or learning philosophy, I can't quite do that, because they require time (10s of 1000s hours each), a resource that I can't spare because it's consumed by work, and other required activities.

I can learn superficially over the course of decades, but the results would be unsatisfactory to say the least.
This won’t solve the problem with maliciuos actors in positions of power, and if we take care of malicious intent (which is really the only way forward) there is no need for technology that essentially exists to avoid having people to trust each other.

> it's just a single variable with a named made of 2 characters.

I have this same problem with programming, when I have to deal with code written by non-mathematicians. They tend to use all these stupid variables with more than one letter and that confuses the heck out of me.
Enums with methods are essentially a compiler supported way of having several static readonly instances on a class with a private constructor. It’s not always useful, but it can be nice, sometimes. I’ve had a few times working with C# where I’d have liked those.

There is real art and artists in the space if you take your time to look for it.

Look at - https://www.fxhash.xyz/ - you'll see a remarkable thing: real innovation, Generative Art being placed right onto the blockchain. Something that would be very hard to monetize only 2 years ago is now a liquid permissionless marketplace for Generative Artists to experiment. It's like shadertoy has become an art market. You can now spend your days experimenting with shader art and make real money. That's incredible to me.
