So the ad had run 88 times when Media Matters took the screenshot? [...] The article doesn't specify what is being counted, but Media Matters was clearly counting something.

I really enjoyed reading this article. Many of the ideas in it were already familiar to me, but the act of reading it was like a meditation, and putting those ideas all together in that beautiful form created a different frame of mind for me. Thank you.

When I got to the very bottom, I read the postscript, which led me to your About page. I was shocked to learn that you work at Facebook.

How is this possible, I wondered. Facebook is continually pouring enormous resources into getting us all to keep scrolling, to generate "that hollow feeling" you refer to, billions of times every day. It's a strong contender for the most effective destroyer, at planetary scale, of the consciousness and ability to connect with ourselves to which Being Alone is an ode.

What a strange mystery this is!
RTL just looks horrifying to me. I had one of those Radio Shack 300 in One electronics kits, but most of the projects were analog and poorly explained. It wasn't until years later, when I saw the simple design of MOSFET logic gates, that my view of computers shifted from "sorcery" to "math".

Granted, with modern transistors getting progressively smaller, computers seem to be moving back to analog sorcery again.
Not a lot of citations other than his own experience. Education is a deeply researched field...this article is not. Just hard for me continue reading when a huge conclusions from the start are based on “it worked for me.”
As other commenters have pointed out, a quality life is dependent on a liveable environment. Moreover, the article isn't making value judgments -- it is just discussing outcomes. This really seems like you're projecting your own political stance, and aren't engaging at all with what is written in the article.

Also, if someone were to distrust science because of a factual article -- well, I don't think science could really do much for them, and at this point in history they're probably best ignored.
This industrial model of human capital production consistently fails. It’s literally the root of everything that is broken about the us k12 education system.

“Taylorism for education but with ‘The AI’” will end the same as the factory model for k12 that gave rise to the pathologies that critics like pg are so quick to point out. ‘The AI’ is just the 2020 version of the control theory metaphors that resulted in disasters in the mid 20th century. Ironic.

I'm going to say that finding out who you are sometimes doesn't happen until you HAVE to find out. Maybe that has less to do with the freedom to explore as it is ... what you do when you don't have that freedom and you're busy with other things.

I know some good folks out there spending huge amounts of time trying to find out who they are, and in the meantime they're challenged with ... really predictable 20 something challenges. Good things like getting outside, learning to climb, traveling and productive stuff. But I talk to them and they seem to expect things to just sort of jump out at them doing some of these things with some truth. But I'm not sure that's when you really learn those things...
He obfuscated the title!
If you look at some of the comments, sources, and just the attitude of the guy that put this together it seems he does have an axe to grind. It kinda says so in the about section. I think if you dive into the mitigations section without looking at that it seems less like that because he ends up having to admit some of them are decent ideas... try as he might to come up with ways in which they're not. There are plenty of OpenBSD users going around talking nonsense but this "systematic evaluation" is not an actual systematic evaluation.

I especially like the part where it lists people who helped but it's all redacted. All of this "research" came from google and twitter. I'd like to see some bypasses to OpenBSD's mitigations and perhaps some ideas and/or code to help improve them or implement ones that these folks say work better. If they're all so bad then it shouldn't be hard for someone like the author or so called security experts he quoted to do these things. Yeah, maybe no one is going to pay for that work to be done... that seems to always be the response when someone asks for proof, code, etc. No one has the time. They sure spend enough time making websites, blog posts, and tweeting about it though.
I'm in favor of a carbon tax, but I believe it would need to be too high at this point to effect change with the necessary speed. Imo a combination of price signals and regulation is needed.

It's still baffling to me that we are expected to believe, for example, that the CIA passes out millions of dollars in war-torn obscenely poor countries like Afghanistan, versus the more obvious assumption that people who work for the CIA have more suitcases full of cash buried around the world than Pablo Escobar ever did.

I feel exactly the same way. Taking notes just distracts me from the original content and I end up absorbing less. When I was still in school, the only notes I took were exact copies of what the teacher/professor wrote on the board, and only if it was something I couldn't derive myself with what I already knew.

I wonder if part of it might be because I write slowly and tend to focus on my penmanship (unknowingly).
The sequel, Echopraxia, is also excellent. Not quite as mind-bending, but has all of the first book's existential creepiness.

> "If you aren't capable of writing good code, you aren't qualified to make the right tradeoff."

So you should probably limit the amount of "good code" you read when you're learning something right?

Or else (as you say) you won't be able to understand why it's good and what trade-off's it will cause...

I guess my main point is, don't dive into the linux kernel if you're learning C, as you'll learn optimisation strategies that probably aren't useful in your context and will only slow you down...
His beef is with broken network and BT stacks, I suspect. Not with the actual underlying standards.
In addition to affirming what I want by repetition, I try to generate logical ammunition for an argument: to think in depth how and why something is bad for me.

As a 9th grader, please consider the idea that there is more to education and life than just making money. Like, good luck with your project, it sounds like you could definitely pull it off....but that's like saying you see no point in staying in school because you're already shaping up to be great at competitive sports or dancing or whatever you're interested in. It's just an activity, not an end in itself.

‘BlueLeaks’ Exposes Files from Hundreds of Police Departments
By the time he wrote this blog post the information available already demonstrated it was an order of magnitude worse than a seasonal flu. People are picking and choosing the narrative they want based on the data they find to match it.

Everyone in the biosciences knew the CFR would be 10-30x (or more) seasonal flu by March. It’s not going to look more like a seasonal flu because it crosses that threshold 2 months ago.

Unlike the flu, it appears you can get reinfected (3-4 months limited immunity), and while it’s unknown if additional infections are as deadly, it’s also unknown if a vaccine will work.

The blogger’s conclusions are based on old data, and they were the day he wrote this blog spam.

There’s a ton of bad coverage of the reality of this pandemic because people who have never stepped foot in a BSL 2+ lab are writing horrible analysis of an unknown problem. My state pretended to shut down, ended the closure order in may, and is at 80% icu bed capacity this week and highest per capita infections.

Arizona didn’t listen and were on track to be worse then NYC’s worst weak in the next 10 days if the infection rate continues unabated.

Viruses don’t like strong UV light, high temperatures, and low humidity, but somehow we’ve gone exponential.

the google lightfield display app for steamvr was absolutely mindblowing, and i remember at the time thinking how awesome it would be if somehow they managed to do it with video, and if maybe someday the rendering algorithm/bandwidth available would allow it to be livestreamed.

Honestly, if you have a VR rig give their demo a shot. I can honestly say this is the one project I've seen where I would hands down quit my job immediately to become involved with it somehow if I had the option. It is abundantly clear to me that the future of media consumption and production will go in this direction. Insanely cool.
I am thankful to Diku and it's derivatives for many important lessons in life. The situation when a mob kills you, takes your exp and all your equipment and you are faced with dire reality of starting all over again from nothing - is the one that we are facing in life ever so often. MUDs have taught me to persevere, focus on what is important and keep going. I am thankful for every friend I met via MUD and every friend I will make. As a matter of a fact I am in the middle of MUD renaissance right now - rebuilding the MUD I created in 1995 and playing it with a handful of buddies - all of us now in our forties and we are having the time of our lives chasing down mobs and magic items (and of course playing only after the kids go to sleep). On top of that I get to code in C again. Life is good. Wish the best of luck to DikuMUD 3.
It's the possible that every single star has a civilization at the level of our's, actively transmitting and detecting, yet find nothing. IE, Earth couldn't detect the signal of Earth if they were transmitted from the nearest star.

How to Grow Your Roofing Business in 30 Days
I wouldn't trust myself to sit down and code a red-black tree. I'm guessing if you find a GH repo with a RB tree implementation, there will be more than a few closed issues because these kinds of things often have many edge cases.

What is more important I think is to understand why a RB tree exists: what are its unique characteristics vs a binary tree, B-tree, AVL-tree, etc.

Same thing with hash tables. If you have never coded a hash table implementation, it may be puzzling to discover there are many, many hash tables, each with pluses and minuses. The real skill is being able to understand the trade-offs and choose a hash table implementation that will work for your specific problem. And when it falls down for some specific data, load factor, etc., understand why.
That would be brainwashing. I've heard you can achieve even better results with a low protein diet.

Ask HN: Consolidated list of Python3 features since Python2?
As per title, is there a consolidated, comprehensive list of changes to Python3 since the first release, over Python2?

A lot of the "what's new in Python3" were written at past points like Python 3.5, it's now at Python 3.8. The latest release notes only cover the latest changes, but will miss everything before.
That would increase the cost, to include both x86 and ARM processors.
There's also the fact that companies will location-shop, pitting states/towns against each other to host a new headquarters etc. So if the company can seek to reduce their overheads for their own financial benefit, why not the staff?
C++ is the worst possible choice for something like this.

I tried compiling it and got flooded with screens full of incomprehensible errors of the sort:

template 'std::__1::owner_less<boost::weak_ptr<void> >'
: public integral_constant<bool, __is_empty(_Tp)> {};
How is what you want much different than the cumulative "What's new" for each 3.x release?

Certainly that will have too much information. u"" strings were in Python 2.x, removed in Python 3.0, and put back in a later version.

But there aren't many of those.
How far away can our own technologies detect our own transmissions? If a planet 100 light years away was making as much RF noise as us, could we detect it? I thought we could.
That's an assertion, but not anything to back it up.

First, threads have been implemented as libraries many times. Second, if checks need to happen theg can happen at debug run time if they can't happen at compile time. I don't know what specifically has to be integrated into a language here that makes throwing away the enormous amount already built in other languages.
This really resonated with me – thank you for sharing, Ankit :)
I get that this was just a toy, but naturally I wanted to think through how to make it useful. Like imagining building a real car from lego.

I know very little about machine learning or cooking or chemistry in general. How would one make this actually useful and interesting?

My guess is you would need to provide a lot more context to the database. Things like chemical composition seem like the most fundamental component of recipes.

Backwards planning from the composition, you could teach it actions that generate those chemicals such as methods of cooking, and the source foods that provide the building blocks i.e. ingredients.

Then at some point you could link it back to the recipes to create standardized instructions for generating certain chemical patterns.

Does that sound like the right way to make this more realistic?

To clarify, the common sense problem is a hard one. It is similar to level 5 autonomy driving. That will take a while to solve. But what we are talking about here is kinda like Waymo cars which can drive themselves in ideal weather at slow speeds in Arizona. So in 2.5 years I think the best chatbots will be as far from having common sense as the current Waymo self driving cars are from level 5 autonomy. Which is to say they will be pretty good.

You had the 300-in-one kit?! I had one of the much older Radio Shack kits, and have many fond memories of those spring terminals.

http://www.zpag.net/Electroniques/Kit/160_manual.pdf

But that lists a date of 1982. I am sure mine was many years before that. Of course it could have been in production long before 1982 - the kit definitely doesn't have an "80s" look.

The size of the actual universe is irrelevant for this discussion since anything outside the observable universe does not have any casual connection to us.

But of course you are right about the absolutely staggering number of stars in the observable universe.
Having done it both ways this would not be my recommendation unless it's necessary - I think it adds a fair amount of complexity.

Some considerations: you'll need some sort of storage mechanism for these flags - is that a centralized configuration service for all your services? Maybe just a table in your database? But database / network calls are expensive to be adding to every single time your code executes the path in question - maybe it makes sense for your service to cache these values locally...but then doesn't that lose part of the purpose of 'fast rollbacks'? Maybe instead of a local cache you spin up a redis instance - but what if this goes down? Will all your instances default to the same value? Etc, etc, etc.

I'm not saying this approach is bad, only that it has complexity, and I find I generally can get away without it.
Streaming. I thought about this in the interfile sense, but not the intrafile sense. This makes sense.
FWIW, I had almost the opposite reaction. I favored this contrarian, also without context.

I was not terribly surprised that I felt this way, but I did try to suppress the feeling, because without context, it's not very rational.

The orthodox member will help reach consensus faster and improve decisiveness, but risks making wrong and/or extreme decisions.

A contrarian adds intellectual value and nuance to a decision, but can cause indecision/inaction.

There's more than just the five gates previously discussed because this was supposed to be a general list of all multifunction gates: that is, if you need to implement anything other than the obvious functions, start here first.

There were also three notes attached to the columns:

1. XNOR = 2-XOR with 1 inverted input = A XOR !B

2. A | !B = 2-OR with 1 inverted input = 2-NAND with 1 inverted input:
A | !B = !(!A & B)

3. A & !B = 2-AND with 1 inverted input = 2-NOR with 1 inverted input:
A & !B = !(!A | B)
