> I can't help but feel we lack a true understanding of gravity.

We have a very solid understanding of gravity [1]. It's just that it's not as accessible as you and I would like it to be [2]. Unfortunately, you cannot argue aesthetics with the laws of nature.

[1] Source: When majoring in physics, one of my exams was on general relativity theory.

[2] As in: Even solving simple symmetrical problems requires dealing with some quite frustrating differential equations.

Learning Python Tutorial: Basics for Beginners
I enjoy Mozart's piano concerti, but I actually don't consider them to be "serious" music. IMHO, they're great music for background listening, but on repeated listening I find they are not as layered or deep as, say, Beethoven's late piano sonatas or Strauss' Vier Letzte Lieder

What I would be reluctant to give up are Mozart's operas, or his sacred music. I couldn't imagine never being able to listen to Dies Bildnis ist bezaubernd schön from Die Zauberflöte, or Ave Verum Corpus.

Very difficult game indeed!
There's actually five of them, not just one: the ’57, ’58, ’97/’157, ’98/’158, and ’99. (Plus four more if you count the open-drain-output types released only by Fairchild, but I don't as they're too annoying to source reliably.)

These guys are super useful. Unfortunately it's somewhat unobvious how best to use them, since the manufacturer literature is written in a very obtuse way. Except for the ’99, they're all just two-input multiplexers. Some have an input inverted and some have an output inverted. The ’99 adds an output enable line and a fourth input, which it XORs with the output. It's much easier to design with these things when you think of them as multiplexers!

I've made a nice chart that I use to help design with these parts, but it's on my work machine and I'm too lazy to log in on a weekend to retrieve it. I've made a lot of nice charts and references... I should figure out somewhere to publish them....

Page 5 of this old NXP PDF was the starting point I used:

https://www.avnet.com/wps/wcm/connect/onesite/8100cb9c-39d1-...

but I removed the redundant entries (most of us know how logic families work by the time this chart is useful...) and added the descriptions of what the parts really are inside.
Interesting perspective! And it seems connecting the dots is part of the role of an educator!
Art and creativity.

The covid 19 lockdown has given us a lot of time to ponder about life. We have ML/AI encroaching on regular work. What can we do when all the routine jobs are automated? I think create is the answer. Artists and inventors start creating.
Yup, for sure. Having PMs who understand infrastructure and distributed systems can be a secret weapon for high-scale businesses, especially in enterprise SaaS where competition is more directly head-to-head.

I've always thought that the civilization series are actually pretty educational: You spend hours and hours in this game, full of real world countries and leaders, and a huge wealth of information is stored in the "civipedia". If you get curious about a leader you can research them and who they were.

You learn, at very high level, how society progressed from sticks and stones to the modern age, and what level of sophistication technology was based on the date. Different forms of government, many other things.

Short answer: seems like OK as long as you do not resell the full body text.

Long answer: Google does the same thing everyday. Each country has its own laws. Usually, news are in a special category that is less protected with copyrights.
Hmm, that's strange. I was born and raised by a very conservative Catholic family in Piracicaba/SP -> Juazeiro do Norte/CE -> Piracicaba/SP. I used to be a rocker weirdo that was often scolded by the local community due to my shirts. Catechism classes were a disaster, even that devil woman silhouette with a pointing tail was criticized.

Anyway, even if my experience is actually an exception and even if those conservative Christian people are minorities, would it be ok to offend them?

I mean, I absolutely don't care. But, now that we're revisiting everything to be as political correct as possible, couldn't we change a picture - that is offensive to a minority - to something else?
Oh boy that e-mail chain looks interesting! But I’ll reserve my judgement until it gets released.
Zero to Production #2: Learn Rust by Building an Email Newsletter
The main reason for the commercial success of Pokemon is the huge array of readily available merchandise and anime/movie tie-ins. How would you go about replicating that with a crowd-sourced competitor? How would I be able to obtain a plushie for my favorite crowd-sourced character without paying the high prices associated with custom commissions?
I watched it recently. I was blown away by how contemporary his points were; this guy passed away in 1987! And yet here he was talking like he's a witness to events going on today! It further shows how things haven't really changed for Black folks for the past 60 years.
As a counterpoint to this, many businesses cannot exist without maintaining CRM database of who their customers are, what acquisition channel they came from, how they have responded to new products / promos / pricing / page designs, direct customer survey data, what payment methods they use, what help center issues they’ve had, what behavioral clickstream of events they used to navigate a product / store / web page, and how all these things vary by time, by seasonality, by gender, by age, by location, by income bracket, and more.

Even if the company has zero intention of selling that data anywhere else, it’s literally a bare minimum requirement to be able to not go bankrupt and layoff all their employees from failing to competition or failing to correctly measure and respond to intricate market signals.

I am a deeply privacy conscious person, but it does annoy me when the counter response to data brokerage or selling personal data is to go way too extreme in the other direction and vilify or try to make illegal the huge amount of data capture that is completely, non-optionally required at a basic minimum level for any modern business to have any hope of not failing.

there is no way i am trying any service out of google now... sorry google, but the trust has broken...
I've built McPiper - simple Gitlab CI/CD pipeline monitor from macOS status bar.

When I work I usually have emails off, so no idea when the pipelines fail.

At the moment functionality is quite basic, but it solves the problem I had.

Also plan to add other CI/CD providers (Travis, Github actions, etc) in the next few versions.

It's my first macOS app, and I've managed to learn Swift + SwiftUI, so time well spent too.

I’m not sure why you’re being downvoted but your comment doesn’t address the issue. Of course Docker will need some pre-allocated space but setting it so high as default seems excessive and ignores the real problems it’s causing to people in that issue thread.

The flag becomes a percentage. The feature isn't always off or always on, it's on for a small fraction of workload, and then that fraction grows as you demonstrate it's safe. Ideally you want metrics that tell you whether the experiment is worse or better than the control group.
Latent semantic indexing[1] uses SVD to identify relationships between words in unstructured text.

You can use it to search for words and find related texts even though those texts do not contain the actual words you searched for. Or you can use it to find similar texts, even though important words may differ.

Not sure how relevant LSI is these days, not my field at all, but mapping words to vector spaces and using SVD like this kinda blew my mind a bit when I stumbled upon it many years ago.

I was worried they had removed it completely. I'm using this for a simple web page which shows RSS feeds from multiple news sources across the political spectrum, and the Reuters feeds have been the essential pivot for me. It is the only source I significantly trust to be neutral in these trying times.

Thank you so incredibly much for this very simple solution. I was worried I'd have to spend many hours on some complicated fix. I'm glad I no longer have to (unless Google kills of their news RSS).
This is a great site, thank you very much!
it is platform independent it seems, will work with any hardware that can take a software client.
Lol, commercially successful ARM laptops is what the op meant.
> The underlying point - that counterintelligence has very often proved to be a spectacular waste of human effort - stands, although that is hardly a reason to be insouciant about mass surveillance.

Mass surveillance causes significant problems regardless of whether intelligence works, and so not only does it make sense for the IETF to write that "Pervasive monitoring is an attack" but I believe that it's morally right for us to say that therefore we should demand our governments desist from such attacks.

But that article takes a pretty typical Adam Curtis angle when it comes to facts that dismantle his core thesis - acknowledge them very briefly and then carry on as if they didn't exist. Double Cross is less than a hundred years ago and took place under the circumstance in which actual spies are more valuable - a war. It can and should continue to be held up as an example of how actually sometimes (in a war for example) there are enemy spies and turning or eliminating them can be significant.

In the modern era we fight a lot of actions short of war. The most significant subsequent military action in the UK was the Falklands in 1982. But something like Double Cross would have been pointless. Britain did not go to war against Argentina. Argentina wasn't at with Britain. Both countries disagreed about the status of the Falklands, which the Argentinians had (for local political reasons) decided to just seize by force. Because this wasn't a war per se, our "intelligence" was mostly just a result of being friendly with the (similarly awful but not hostile to us) regime in neighbouring Chile. No James Bond types, just somebody who will turn a blind eye to human rights abuses and focus on immediate military intelligence resources.
We have approximately the same kid layout, just a few years further down the road (twins with an older sibling). Once kids are in school, the situation changes dramatically. School ends up consuming a big chunk of the "work" day, so keeping up with work takes up much of what used to be "family" time, net result is that there is far less free time now than there used to be.
Good point. Being more of a movie guy than a gamer watching some of the stuff these days on screen I keep wondering what education would be like if the people behind the Matrix or Pixar or Tom Cruise were involved in the design (alongside the pedagogical expert).

That's what I'm missing, what are your sources to think that? I somehow haven't seen that in the links you gave.

OK. I didn't realize that trick where you multiplied by 4 there. So it works when you're starting with any integer number of feet if you do a little multiplying.

But I still doubt this has any practical use. Can you give me a concrete example where you or anybody you know has done this? How common is it?
> If your statue doesn’t unequivocally reflect only one good message to all people, you’ve got a problem.

I'm not sure that even a statue of Gandhi could meet your standard.
An ISA doesn't just exist in a vacuum. There is also the compiler toolchain, runtime libs, developer mindshare and years of very smart people thinking about the ISA.

A $1e12 company doesn't have to pick the "pinnacle" of ISA/CPU possible. They just have to pick one that is good enough to meet their financial goals.
Didn’t Apple invest in ARM in 1990?
No. In his post about it he says he has very bad ADHD. He's having treatment but it's not working well at all. He can't write a blog post because his brain gets tied up in knots thinking about writing and editing a long post, but he can write short scribblings.
Ask HN: Explain why apps like FB/Shopify are more than CRUD applications?
I have not worked for large internet companies and I want to know why there are so many engineers working on seemingly simple CRUD applications like FB/Uber/Shopify etc?
I created a support ticket with my RSS reader (Newsblur) about this issue concerning you! It appears to be quietly feeding me hvper.com articles from the now non-functional feeds.reuters.com (https://forum.newsblur.com/t/where-did-hvper-news-come-from/...).

I don't supposed you know how this magic could possibly happen?
I think you fail to grasp the sheer amount of time to create a new instruction set, easily a decade to get to the level ARM is now. Not just the hardware, but debuggers, tooling etc etc. Can't see that paying off

Also, the kernel codebase, which is shared with iPhones, will be able to target a single architecture
>For $150 you can buy a cheap Intel based PC laptop with Windows 10 on it.

Is there any point in a $150 computer, especially if it's $150 including Windows?
I like how the DeloresDev/Prefs.json you have to update isn't JSON but a simple "key: value\n" file.

Saccades are a great demonstration of the idea that consciousness is actually very different to what we intuitively imagine it to be.
Temple OS seems impossible, and yet exists.
Blackmail out in the open - I like it /s.
You mean esp-who ? It uses mobilenetv2 so it's quite possible to train it to detect person instead of face. Didn't tried myself, just started playing with it.
I think the more interesting possibility is that one may have to jailbreak a Macbook Pro to run your own apps and/or OS.
The instruction set matters less for performance than people think. But it does matter a lot for the ecosystem: low-level hyper-optimized libraries for certain operations (think BLAS), tooling, developers understanding how to best write for it, etc. Creating all of that will take a long time no matter how much money you throw at it. For ARM, that ecosystem is probably the second best in the world, and in particular Apple has been building it up for themselves for more than a decade since the first iPhone.

Additionally, sharing the ISA means that the ARM reference cores will always be available as a backstop if Apple's custom chips start running into trouble for whatever reason. IIRC, Qualcomm was doing a lot of hopping between full custom cores and ARM reference ones depending on which one happened to work better some particular year.
The pub analogy or even the Facebook group isn't very good.

Tweeting involves getting your short thoughts evaluated and rated by strangers at scale! You're also regularly aware of the properties required to (potentially) go viral.

It is far more difficult, by design, to encourage better conversations there.
ISAs are somewhat orthogonal to performance these days, so this move is more or less switching to Apple CPU designs. Apple has rapidly iterated and improved in-house designs since basically the A4 iPad.
RunKit Is Node Prototyping
Well, a bigger connector likely wouldn't work for phones then, would it?

As far as I can tell, phones are the #1 thing people are plugging in and out these days.
Of course. You can get great deals from used/refurbished business laptops for that price.
(Not IRL) Pride Tech Summit: June 22-26
This is something that I’ve been thinking a lot about recently. I’ve been able to self host quite easily as I’m very technical and capable of setting up and managing a Raspberry Pi, a NAS, and a VPS.

One of my dreams is to make a device that would make self hosting easy and cheap enough that anyone can do it. Something like a Chromecast, where it’s a <$50 device you plug in and an app guides you through your setup. From there, the device could have a platform like Cloudron or YUNOHOST where you install services via an “App Store” like index.

The open source, self hosting community is getting quite robust now and I don’t think it will be long before it’s really feasible.
Hmm, The Oregon Trail comes to mind as an educational game which was quite fun, and clearly sold to a lot of institutions. Do you have any thoughts on how that came about?
(I'm not Mark) but I would expect it was an issue of space. About 6 years ago my wife and I moved from a house with a full basement to a condo. The house had 1200 sq feet, and the basement added another 1200 sq feet. The condo had 1400 sq feet. I had to get rid of about 1000 books and my wife had to get rid of more than 2000 books.

I'm OK with ebooks (I actually prefer them), but my wife loves the feel of a real, physical book in her hands. Because of Covid-19 she has been reading more ebooks, but as soon as the library opened back up (with limitations) she went back to requesting as many books as she could.
You should feel a distinct click when you plug in your connector. I never had any problem with my laptop.

What you described can be caused by lint inside your USB-C port. I had this problem only with my phone. Try to get it out with a toothpick.
Regarding treating the other eng. teams as customers, I fully agree. I know it's not something everyone does (Been there, argued that), but when you treat them that way and when you deal with their problems (Service xyz requests are too slow, feature xyz would really solve our problems ...) you will, in the end, help the customers.

If my coworkers need my services, then that's because they are developing something that a customer needs. I think of it like a dependency-tree. As long as you trust your company to not have multiple teams develop something that will never see the light of day, or something the user doesn't want or need, then this mindset is absolutely a good one (Sadly been there, done that too).
That argument has sadly never worked. It's too easy to dismiss as an exaggerated analogy. I also think it's wrong to assume everyone outside tech is a clueless sheep. People are often well aware of the implications but think it's "worth" it. They simply don't care and draw the line somewhere between giving their data to Big Tech and live in a glass house.
I have to agree on Reuters... They seem to make the effort to keep the context with unbiased framing.
Additionally, the importance of this use-case (from Apple's perspective) has decreased significantly since they originally developed Boot Camp. While I'm sure that many people do run Windows on Mac hardware, the percentage of Mac owners who do this is likely dropping significantly (if I remember correctly, there was a statistic about this in a comment on another thread about ARM Macs).
I expect the price will not budge at all.

That was a great story about actually managing to debug a wireless problem. I wish there were better diagnostic tools commonly available that would clearly explain these things. I'm not sure if in the author's case there is some software that would listen for extensive polling and flag that as an issue - even better if it could log running programs at the time and try and guess which one is causing the issue.

I'm constantly having problems with my mac laptops and after many hours (10+) of internet searching I still have no idea why the wifi doesn't always work reliably. Some days or weeks (months?) it is great. Other days every hour it is disconnecting. Sometimes resetting the router helps, sometimes it doesn't. The whole situation is extremely frustrating.

Some issues:
Why am I getting a DNS issue when my wired desktop never has a wireless issue?

Sometime I swear that the laptops becomes much less reliable at the opposite end of my house as my router but the signal strength is generally still excellent (4 bars).

Anyway, I'm not asking to have my particular issues solved (although that would be much appreciated!!!!). The real issue just seems to be that debugging these issues is extremely difficult and not based on principles but just random things that people can try (e.g., delete your plist files).
But what if someone wants to Boot Camp ARM Linux?
To emphasize where the topology comes in since it wasn't clear to me at first: the important bit is the saddles. Just before a saddle goes under, there are two important properties

1. there are land masses on both sides of the saddle. This would not be true if the polytope had holes.

2. if the lakes on either side of the saddle are joined up, the only way they can do that is if the lake circles around and encloses at least one of the two land masses (Jordan curve theorem). Once the saddle point goes under, that land mass is cut off from the "mainland". This would not be true if the polytope had a handle. The lakes could be joined up by going along the handle without enclosing one of the land masses.

It’s a very common anti-pattern to think whatever worked for you will universally work for others. Some need more hands on, some need less. Few kids are entirely self-motivated.
We also tried to make educational games and came to a similar conclusion. The truth is, kids (or adults) don't want to play "educational" games. They just want to play fun games.

And, let's be honest, games that try to teach you math or science are just not as fun as Fortnite or Minecraft.

Now, you can make the case that some games are educational by mistake. Like Minecraft, Age of Empires, Sim City or Kerbal Space Program. But noone would see them or describe them as "educational" games.

So, what we're trying to make now are creative games. In my opinion, creativity is extremley important and there are fun ways to be creative, that are not eductional in the strict sense. For example, Lego comes to mind.
That basically already exists in the form of Catalyst.
Given that my iPhone's A11 Bionic beats my desktop's i5-7400 on Geekbench's single-core benchmark, I would expect that a newer desktop-optimized Apple chip would destroy most Intel laptop chips.
