I agree, the pandemic has changed so much of today's childhood. I myself am a science educator and a mother of twins girls 4 years old.and yes, I used YouTube so many.times to find something fun but educational that I can do with my young kids too, and I found the videos boring for my kids or requiring way to.many items for me to buy. So I created a series of videos with quick STEM educational activities for young kids and parents/educators to watch and play together, in parallel to the video. I only use household items and aim for very very low cost & quick preparation so you can do it together with your little ones avoiding long boring preparations! The videos are playfully designed encouraging kids to feel happy and excited for science activities so they can have fun and learn:) maybe it would be helpful for you too..
For example,this is a fun educational kids science activity with colors and paper towels - You can show kids how to do it a couple of times, and let them play independently for ages. It teaches them the basic elements of how water is transferred through paper towels just like a river. Also, when the washable colors are traveling with it, they are mixing and creating beautiful art pieces different every time, which is very engaging for young kids.You can also extend it by:
1) Demonstrating the creation of secondary colors by using exclusively primary colors.
2) Connect new pieces of kitchen paper towels to existing paper towels and monitor how the water and colors continue to flow.
3) Try using normal paper and/or toilet paper and monitor the colors and water flow. Watch how the colors do not travel the same way as with the kitchen paper towels because different materials allow water to flow from them in different quantities and speeds.

I hope you like it:) let me know your thoughts :)

> As far as I know there has been 1 reinfection case in the entire US

Wait, really? A recent article in the Dutch news [1] mentioned the first death by reinfection, and also mentioned that there were at the time 23 other reinfections were known worldwide. Seems odd that there'd be just a single American in there, given the number of infections in the US.

Scared people don't care about probabilities. We have known for months that the IFR is <0.01% for people under 40 and even lower for children, youth, and young adults. Yet they still blabber that everyone is in grave danger.
A lot of things that used to be imperceptible are now perceptible thanks to precise measurements and systematic, complete and reliable written records. For example, an average change in temperatures of 1 degree over one century used to be imperceptible, now it's not.

Yeah. It's meant not to connect until sufficiently in sync. Running out of sync apparently results in the grid nudging the generator into sync, but here the discrepancy was so large the nudge became a percussive encouragement of significant enough magnitude for the generator to permanently take a seat and reconsider. (that sentence was fun to write)
The "datacentre" mentioned is not necessarily an enterprise datacenter or a web app backend datacenter.

So I actually had a basic algebra system before they taught it to me, for what it's worth, probably something I figured out from the structure of the language my parents were using (both accountants). I'm a pretty rare individual, I've never had to work at math.

I took a long time to learn how to learn from example, it used to be impossible but now it's almost just as natural.

Data diodes exist and have been used in high security or other risky cases when one circuit or bus absolutely has to be isolated except for one way communication.

In practice it's not typically necessary to go quite that far if a trusted communication processor is able to pass messages or set registers but only ever takes logic control flow input from the "safe" side. Plenty of equipment that wants to broadcast state over radio but never accepts any sort of input back beyond acks or whatever has done this for a long time.

Me too. First follow from external website to previously unvisited tweet, there's an error. If I open it again it works, and keeps working from then on. Also happening 100% of the time on new tweets.

Kinda funny that twitter can't figure out such basics such as opening a page correctly when following a link. This has been happening for months.

React vs. Svelte- a Comprehensive Comparison Between JavaScript Libraries
Great napkin math. I'd like to also add that Starlink is a project that plays along really well with their main development: Starship. Starship will bring Starlink costs down, but that's not the real benefit: what they really needed was a product to increase Starship launches in the short term. They need something to prove it's reliability. Starship won't have a separate abort system, and yet Spacex wants to fly people on it. Not only do they want it human rated (NASA spec for this is >1:275 launch failure, which is still quite high), they _also_ want routine intercontinental civilian flights. New york to Singapur in 40mins. But again, to do this they need to prove they're as reliable as an airplane, and to do that they need volume. Traditional satellite market has proven very slow to move and take advantage of cheaper prices, so Spacex does the next best thing: create its own volume.

On the subject of right to repair: Back when slide out keyboards were still available I bought I a new Verizon phone and paid for the best insurance plan I could get. After a short amount of time my brand new phone just stopped working, the insurance said it was a factory issue, I sent it in for repairs. They couldn't fix it so they sent back a certified refurbished phone. It wasn't the same quality, the new keyboard was clicky and the refurbished felt spongy. I called to complain but I ended up in a support loop getting passed around in a circle of people who had no authority to fix my situation. I paid for a new phone with full insurance like a good little consumer and got a used phone.

Ever since then I buy budget phones; phone insurance is a scam, phones are intentionally difficult to repair, and I don't want to spend $1k on something fragile that I keep in my pocket that has a high likelihood of being dropped on accident and the only recourse being whatever policy Apple has to benefit itself. I wish we lived in a world where consumer electronics were owned by the user. A 30 year old NES can hold value, I have doubts about what 30 year old smart phones will look like.

How Scrabble Blew Its Big Moment
Also, for the way most modern CPUs are used: how do you task switch? If the hardware is large enough, you can deploy multiple configurations at a time, but does software support that? Is is possible to have relocatable configurations?

In theory, you could even page out code, but I guess the speed of that will be slow. Also, paging in probably would be challenging because the logical units aren’t uniform (if only because not all of them will be connected to external wires)
Interesting approach. He starts off with vector spaces, after providing some intuition, and uses it to drive the rest of the book. He defines matrices in terms of linear maps, and talks about operations on vector spaces, with small sections dedicated to the corresponding matrix computations. There's no hand-waving or lack of rigor.

Overall, a fine textbook.

It's refreshing to see that a functional organization is a viable alternative to the product-based divisions that most startups and companies adopt nowadays. Also management by experts seems inspiring:

Agreed, I originally thought this might be an older project from a couple of years ago because of the ES5. “Vanilla” doesn’t have to mean “supports IE11” in 2020 (before anyone jumps on me, yes, depending on your users you may very well still need to support it, but it’s very clearly on the way out - finally)

What happened recently in AMD's market ?

AWS based ARM processor looks to be widely deployed in the cloud.Nvidia, the leader in GPU compute in buying ARM.Intel, which has suffered deeply because of their 10nm fab problems are going to work with TSMC.And AMD's P/E ratio is at 159, higher than Amazon's!

So Maybe AMD is looking to convert some inflated stock with a predictable business.

And it's better to invest in a predictable business that may have possible synergies with yours. Otherwise it looks bad to the stock market.

And Xilinx is probably the biggest company AMD can buy.
This is a good question.

I think English itself is lacking a bit here—ie: it’s very common to say “you guys”, semi-regardless of gender of the subjects, because we don’t have a 2nd person plural tense.

The original line was a joke-ish, so here are some options given that context.

“Ma,am” - very formal, often read as exaggeratedly polite. You’d be most likely to see this in a customer service context, hence the meme: “Ma’am, this is a Wendy’s” when people rant inappropriately.

“My dear” - gent(/i)le, but can be read as misogynistic or belittling if you’re a man, especially one of higher “status”. From a female and/or peer, reads more as motherly advice. Use with caution.

“Lady” - sort of splitting the difference. Formal, but more what you’d hear from a grumpy bus driver. Probably funniest option here.

“Girl”/“gurl” - slangy and youthful, more a loan word from the drag community. You’d probably get downvoted on HN for it and upvoted on Reddit.

“My dude” - more current jokey response, it’s been churned through Twitter and youth culture to the point where it’s meaningless enough that “dude” almost works for either gender. Probably don’t use this one, might even get downvoted on Reddit.

Edit: god, sorry this turned out long, but it’s a pretty fun exercise.
I think most shops that are run by people who have experience with software development will tend to choose languages that are fairly mainstream. Yes, the recruitment pool is bigger, but so is the entire ecosystem. Tooling, libraries, books, documentation, easy to find knowledge, long term committments etc.

There are few things that are more frustrating than working on something that so few people work on your search results when looking for solutions to problems come up nearly blank.

And despite what high thoughts we programmers have of ourselves: we spend an inordinate amount of time Googling things :-)
> People signing up for a test through Verily had to do so online, using an existing or newly created Gmail account

Talk about burying the lede. I thought it was bad when Facebook required an account to use the Occulus[1]; for an Alphabet company to require a Gmail account to get a medical test under a public partnership seems quite out-of-touch. Based on this article it sounds like California made the right call to abrogate the relationship early (provided the freed-up funds could be reallocated to more traditional, less-invasive testing services)

Yeah, the advantage here is that once you wrote your Pratt parser it's a nice, quite generic piece of code that you can just drop into any new project, reconfigure a bit and it does it's job.

Don't know what page you mean, but personally I first stumbled upon it on Douglas Crockford's page [1]. A couple of years later Eli Bendersky did a nice writeup for Python [2].

I wrote my first Pratt parser in D, based on Crockford's. It was a learning project that ended up as a Javascript interpreter. I parsed JS into a Lispy syntax tree and added a simple Lisp interpreter based on Norvig's [3].

In the meantime I've switched my default language (to Nim [4]), but I've since never used anything but RD and/or Pratt for any parsing job.

as easy as profiling with Austin itself. Just pass the pid of the web server

sudo austin-tui -Cp <webserverpid>

See https://github.com/P403n1x87/austin#examples for more details. To avoid using sudo on Linux you can do

sudo setcap cap_sys_ptrace+ep `which austin`

and then simply

Everybody seems to view this as AMD mimicing Intel when it acquired Altera. (That acquisition has not born visible fruit.)

My contrarian speculation is that this is a move driven by Xilinx vs. Nvidia given Nvidia’s purchase of Arm and Xilinx’ push into AI/ML. Xilinx is threatened by Nvidia’s move given their dependence on Arm processors in their SOC chips and their ongoing fight in the AI/ML (including autonomous vehicles) product space. My speculation is that this gives Xilinx an alternative high performance AMD64 (and possibly lower performance & lower power x86) "hard cores" to displace the Arm cores.

Interesting times.
Why I Stopped Using ORMs to Get the Job Done
What Is Happening to the Supply Chain?
Thanks for doing this work! Postgres is amazing and this area is the one place where eg. MySQL has a clear lead.

> Postgres is an open source project. It's useful in a lot of cases. It's not in some others - partially due to non-fundamental limitations.

For me at least, postgres has the problem that it's too useful. It has so many clear advantages over the alternatives that it often makes sense to choose postgres over more specialized tools.

For example, even if I was primarily storing JSON data, postgres is still a good choice, because it offers better consistency guarantees than most document databases, and has a more powerful query model.

The end result is that the few limitations remaining (eg. the connection model) are felt all the more strongly: I cannot simply say "ah I need lots of connections, I'll use MySQL here" without also giving up on all sorts of other features that I would normally use. (Although MySQL is still improving)
Another artificial restriction by Apple?
> - UK + Ireland: quite frankly a bit of a mess

That is mostly true. However, I would note that Ireland were kinda screwed in some respects by the border with Northern Ireland, which is part of the UK and thus has the incredibly poor response of England and the Tories. We've definitely made a bunch of mistakes, but it would have been a lot easier to deal with Covid were it not for the border (and our vast under-investment in our health service over the last 20-30 years).

It's worth noting that the UK cases are far worse than they seem, as uniquely amongst European nations, they only test symptomatic people, even though we know that asymptomatic spread is a big problem with Covid.
Technically, the kernel does not need to care, other than providing an API to create a 16-bit alias to a handle. An API which the 32/16-bit APIs will use transparently, as well as 64-bit programs explicitly whenever they want to send to a potentially 32/16-bit process.
You would use precompiled modules or compositions of these modules (pipeline or parallel).

This can be a relatively fast operation. Seconds or less depending on complexity.
Giving up on politics is often tempting. It is also risky
Also in the Northeast and take advantage of this occasionally. I took a hunter safety course recently and they hammer it in that this model is changing as more and more land is bought by people moving to these areas from places that don't have this custom or land gets passed to generations that don't share this ideal or don't want to bother with people on their land (many times for good reasons).

I personally love it and would probably never post my land, but I feel like it is one of those nice things that can be described as "just the way we did things back then" that won't last much longer.
> "teaching materials" are rated higher despite being exactly the same in the cookie and non-cookie courses.

Your experience of the same teaching materials could be substantially different in a class with cookies - in a more informal atmosphere, students are more likely to discuss the purpose of the materials and therefore have a better insight into their value.

(The atmosphere this creates is also likely to persist over multiple sessions).

> cookies are provided only in the session of the course where the evaluation is performed (note the phrasing "course session", not "course").

I agree that would be relevant, but the Methods as it is written contradicts this. It says cookies are provided during a "course session" and the evaluation happens "after the course" (the implication is that this is not during a course session)

From my understanding the GBAPI card is meant to work on 500's too hence the ability to snap off the end of the edge connector (some others need -5 which isn't available on the 500 connector) but afaik the ACA500 is not friendly with autoconfig devices and I'm sure when it was designed there was an assumption that there'd be no other devices in the autoconfig chain
https://discourse.julialang.org/t/blas-vs-cublas-benchmark/4...

Here's an OpenBLAS vs CuBLAS performance comparision. Basically CPU is at this point outdated technology for matrix multiplication. Your second comment is more interesting, I'd be happy if Julia gets to the point when it can beat PyTorch or even JAX on training Lambda networks or Performers.
I may be an outlier, but I like this approach. I see it as taking away bad choices; fewer things to worry about, fewer things to suck battery, fewer things to break.

A simpler design often correlates with a sturdier design, too.

To take the AppleTV NTSC/composite plug as an example: I won't ever have to worry about having to explain to my mom which cable and connector to use when plugging it in.

That said, their "simplicity" should not come at the cost of repairability (replacing batteries, …) and openness (running Linux, …).
