Nice to see RTL (resistor transistor logic) circuits again! They were my introduction to digital logic back in the mid-1960s.

I was getting into ham radio at the time, and my neighbor across the street was a sales engineer with Motorola. He saw me putting up an antenna and said "hey, it looks like you're into electronics, let me know if you can ever use some free samples of our integrated circuits. Here's a databook to get you started."

I really wanted to make an iambic Morse code keyer. This is the kind that has a paddle with two independent levers, one for dits and the other for dahs, and if you squeeze them both at the same time it alternates dits and dahs for you - thus the name "iambic" [1].

So I designed a circuit using the RTL chips, gave my neighbor the parts list, and a week later got a nice box with the parts I needed. Put together the circuit and it worked!

Of course I didn't know anything about RF shielding, and RTL circuits were particularly susceptible to interference. So when I hooked the keyer up to my transmitter and tried making some contacts, it mostly worked, but sometimes it would just start generating dits and dahs all on its own because the transmitter would feed back into my iambic circuit.

Naturally the hams I contacted started laughing at me (as much as you can laugh in Morse code) and said "what a lid!" [2]

It was fun though.

I used to play so many of those educational point and click games as a kid. Don't remember the details well but it seems the style has died out in the last decade.
> What’s your opinion of cookie dialogs on every web app? That’s the direct result of the web being an open space that is regulated by governments rather than Apple.

No. They're both the same thing. One entity deciding a policy that is not in the best interest of the participants in the ecosystem.
yes, those are valid criticisms of the distortions wrought on our representative democracy by elitism. people with money and power wanted that layer of indirection (at least since the 1700s) because they feared that the people would actually get what they want, which could include adverse actions against the elite. it was an unfortunate but unavoidable compromise at the time. that, and true direct democracy was practically impossible until the past few decades for a polity the size of a country.

to be clear, i'm not arguing that governments are bastions of fairness and enligthenment, just that they're not much different from other power structures in that any institution (and especially the confluence of those institutions) is a threat to individual liberties and civil rights. however, governments are the primary mechanism of protecting and extending rights and liberties.

the cause of discriminatory injustices like jim crow is not simply the representative form, but rooted in the people themselves--the collective us--as expressed by our differential power and influence. the wealthy simply have outsized influence over all policy, for no discernably valid reason. why should we ever give people who are particularly greedy the power to largely control social policy too?
I think you probably should be pointed in the direction of your last statement, but hey, that’s just my direction.

The lesson here reminds me of one of my favorite Malcolm Gladwell essays about McDonald's failure to market healthy fast food back in the 90's:

The McLean was a flop, and four years later it was off the market. What happened? Part of the problem appears to have been that McDonald's rushed the burger to market before many of the production kinks had been worked out. More important, though, was the psychological handicap the burger faced. People liked AU Lean in blind taste tests because they didn't know it was AU Lean; they were fooled into thinking it was regular ground beef. But nobody was fooled when it came to the McLean Deluxe. It was sold as the healthy choice--and who goes to McDonald's for health food?

By that logic, nothing is actionable because someone else might prevent it happening. It being derived from the Maersk incident is probably among the better arguments for pushing it against that sort of resistance, since that is something business higher-ups have have heard of and are scared by.
Systematic research using large datasets shows that public sector organizations are associated with significantly worse management practices.[1] Public sector organizations are nearly as poorly managed as the worse category of private sector firms: those run by the heirs of the original founder.

In particular public sector organizations have significantly worse incentive structures, are much more likely to promote based on tenure rather than competence, and are much more likely to retain low performing employees.

In the process of "dredging up the dead", it seems to be having the side effect of people forming strong but inaccurate perceptions about the degree to which literal racism exists in America and the world today, which has the side effect of causing serious polarization and unrest in society.

This isn't to say we should or should not do these things, but being mindful of what is actually occurring might be worthwhile.
I think the answer here is simple and not as profound as people might think. Square matrices are linear operators which map an input vector into a space with the same dimensionality. We can characterize a few interesting symmetries when a matrix happens to be square.

As such, we have more rules and theorems around them, making them suitable for practical usage. For example, physics deeply utilizes Hermitian matrices, which are a special subclass of square matrices. Spectral theory is incredibly important in all sorts of applications.
If its the first game you have played in that category, you havent played the best.
‘A Year's Worth of Suicide Attempts in Four Weeks’: The Unintended Consequences
Exactly. The cost and time of transportation would seem to far outweigh the cost of a home office in the long run. My main concession might be the cost associated with paying for high speed internet, if much of that bandwidth is going to be used for work purposes.
Snow Leopard is my favourite OS to date. It was blazing fast and got out of the way. After that, it kept getting worse gradually...

No, because the best way to motivate an engineer is to tell them something is impossible.
Gilbert Strang covers a this well in his "18.065 - Matrix Methods in Data Analysis, Signal Processing, and Machine Learning" course [1]. I can highly recommend the lecture series to anyone interested in such topics.

This is based off the assumption that 25% of healthcare workers could have been exposed, but they only detected antibodies in 4%. Haven't there been recent studies in the US showing that infection rates among healthcare workers are low? It seems more likely to me that the 25% estimate is just way off.
There is also the interesting case where spies and intelligence can be TOO good.

It goes something thing like this:

- Spy for Country X picks up intelligence that Country Y is about to do crazy thing A. This information is 100% true and correct.

- Country Y is not in the habit of doing crazy things like A.

- Given that, the government of Country X thinks "This must be false because country Y would NEVER do such a thing."

- Country Y then goes and does thing A.

There are MANY instances of this throughout the history of intelligence services and I always think of this type of scenario every time I hear "well spies are just terrible."
It's a tool. You take a hammer, you can use it to build a house or you can bash in someone's skull. I estimate more houses have been built than skulls bashed in.
I think the use case for Flag Theory tactics are becoming increasingly evident, especially in these wonky times.

Autonomy is a tough thing to hash out in the modern world. It's not easy to do things like get a 2nd passport or residency, legally minimize your tax obligation, travel in accordance with various country's rules/restrictions so you can live such a lifestyle.

I may not yet be living the Flag Theory lifestyle and it may not it be easy but god damn it, it's going to be worth it!
Ask HN: Why do bad reviews get me black listed?
I started a small and niche media company that reviews tech products, late last year. I have no references to substances, politics, profanities, gender, bias, or anything of the sort to make me blacklisted and I don’t have a odd look as in a haircut that would get me in trouble. Most of the products I review get average to great reviews. Since the lockdown, I got even more attention but nothing major like the mainstream folks. One of the companies I work with sent in a product so I can review and I gave my honest opinion that it wasn’t a good product. Next thing you know, the company I deal with that deals with the company that makes the tech terminated our relationship. They also pulled ads from the site. I’m also not barred from attending their tech stuff at show floors but I won’t be given tickets. Is this common in media companies? Please note this is my first foray and have done everything I can to be company friendly
Yes, yes it is. That will force open hardware specs, right-to-repair, limit damaging DRM, and encourage competitive software and hardware markets. And even multiple software stores, if that's what the market wants.

Yep. It works for most news sites, it's just filtering the recent news from Google News based off the URL. Oddly, it doesn't work for CNN. Never understood why. Maybe "cnn" is a stop word to this search engine and ignored. Dunno.

And, of course, it works today. It's a Google product, so enjoy it while it lasts.
Fascinating to see what my old university has been up to!
> You need way more processing power than an RPi to do this at 30fps, and C/C++, not Python. (There are literally dozens of projects for the RPi and TFlow online but they all get like 0.1 fps or less by using Flask and browser reload of a PNG... great for POC but not for real video)

I think 8 streams at 15 fps (aka 120 fps total) is possible with a ($35) Raspberry Pi 4 + ($75) Coral USB Accelerator. I say "I think" because I haven't tested on this exact setup yet. My Macbook Pro and Intel NUC are a lot more pleasant to experiment on (much faster compilation times). A few notes:

* I'm currently just using the coral.ai prebuilt 300x300 MobileNet SSD v2 models. I haven't done much testing but can see it has notable false negatives and positives. It'd be wonderful to put together some shared training data [1] to use for transfer learning. I think then results could be much better. Anyone interested in starting something? I'd be happy to contribute!

* iirc, I got the Coral USB Accelerator to do about 180 fps with this model. [edit: but don't trust my memory—it could have been as low as 100 fps.] It's easy enough to run the detection at a lower frame rate than the input as well—do the H.264 decoding on every frame but only do inference at fixed pts intervals.

* You can also attach multiple Coral USB Accelerators to one system and make use of all of them.

* Decoding the 8 streams is likely possible on the Pi 4 depending on your resolution. I haven't messed with this yet, but I think it might even be possible in software, and the Pi has hardware H.264 decoding that I haven't tried to use yet.

* I use my cameras' 704x480 "sub" streams for motion detection and downsample that full image to the model's expected 300x300 input. Apparently some people do things like multiple inference against tiles of the image or running a second round of inference against a zoomed-in object detection region to improve confidence. That obviously increases the demand on both the CPU and TPU.

* The Orange Pi AI Stick Lite is crazy cheap ($20) and supposedly comparable to the Coral USB Accelerator in speed. At that price if it works buying one per camera doesn't sound too crazy. But I'm not sure if drivers/toolchain support are any good. I have a PLAI Plug (basically the same thing but sold by the manufacturer). The PyTorch-based image classification on a prebuilt model works fine. I don't have the software to build models or do object detection so it's basically useless right now. They want to charge an unknown price for the missing software, but I think Orange Pi's rebrand might include it with the device?

I stand corrected. Can you link me to a mainstream media article showing a black Karen? As far as I knew it was directed at white women. A quick Google search shows the search engine itself is suffering from the same misunderstanding about “Karen” I was, so I’m going to kick responsibility for my mistake up the chain. It’s not my slang.
In my experience there is a lot of crappy and hard to use tech in education that if improved would make things much easier.

In highschool we used this system (https://www.managebac.com/) which I found to be incredibly useful and easy to use and everything was logically placed in the same application. Then when I went to uni we had about 10 cobbled together applications that were all crappy and confusing and my results definitely suffered when I failed to find important information and notices.
This is extraordinarily neat.

Home Assistant does have a tensorflow integration [1] that allows you to run other home assistant automations (including various alerts, alarms, and scare sequences) based on person detection with basically any camera (since it's kind of a hub-and-spoke model to all other possible IoT devices).

[1] https://www.home-assistant.io/integrations/tensorflow

I struggled recently to get it running on my actual GPU since I run Home Assistant on a home server. I ended up making a custom component using pytorch instead on Pop OS 20.04 and it works gloriously. CPU usage way down and GPU has something to do now.

My super awesome self-hosted alarm system is now extra-super awesome.

Of course burglars are going to all just start wearing AI adversarial t-shirts.

People comparing flu to covid need to be aware that sentences like this (from your Hopkins link) pack a lot of hidden stuff about the different ways of counting death:

> In the U.S., from Oct. 1, 2019 – Apr. 4, 2020, the CDC estimates that 24,000 to 62,000 people died from the flu. (The CDC does not know the exact number because the flu is not a reportable disease in most parts of the U.S.)

Those estimates are complex statistical modelling that use a combination of laboratory confirmed cases, death certificates, excess mortality, but also sampling of calls to primary care for flu like symptoms.

The Covid-19 deaths talked about on the Hopkins page are complex, but they come from states and many states are reporting deaths for people who were confirmed by testing to have had covid-19, or where covid-19 was listed as the cause of death (but not just listed) on the death certificate.

It's old enough to not get any security updates. Doesn't that concern you?
Video games will become a much more powerful force at sparking kids' interest and creativity in a subject, which will lead to better educational outcomes. In my experience, video games are a fantastic way to learn the initial 50% of a new subject, and to appreciate and enjoy it. Some anecdotes from my life:

- I learned programming through an in-game (Star Wars Galaxies) scripting language. That little bit of experience automating repetitive tasks set me up to excel in high school and college programming courses, which led to a career in data engineering, and now AI and robotics.

- I was introduced to game theory by a prisoner's dilemma situation in a video game (KOTOR).

- I learned economics and market forces by trading on Runescape's Grand Bazaar, and how to model and optimize a production system by managing a little island kingdom.

Not only did I learn new subjects from these experiences, but learned that I could excel at and have fun giving them my attention, on my own time and for my own purposes, without the external pressures of grades and tests. This gave me the confidence and energy to pursue them more deeply in school.

One thing that's interesting about all of these experiences is that they were all multiplayer and extremely social games (KOTOR, while a single-player RPG, was played with siblings and friends). I suspect that the social aspect was a primary motivating factor, and wonder if that principle holds for the broader population. I certainly wasn't the only kid in my class trading on the bazaar to get some extra GP.

Hey, same situation! As the resident rabid FP evangelist at work, people are often surprised by how much I like like TypeScript.

Personally, I think structural typing systems are the path forward for functional languages, and that means accepting that Haskell needs to go to move on to a retirement home. I was pleasantly surprised by how well Scala did subtyping with ZIO's `Has` + variance annotations. Shame TypeScript is bivariant with function parameters.
The title can't be serious... Computers allow designs for planes, cars, and other devices to be modeled and understood better than was ever possible by hand. Progress on fusion reactors relies on computer modeling of plasma flows that was impossible to do by hand. Weather forecasting saves lives and uses computers to model weather patterns, uses satellites (that have computers in them) to collect weather data. From medical devices, to communication, to industrial applications... computers are used throughout the entire economy.

I think this article should really be: web developer wonders if there's more to computers than websites. Because I guarantee the scientist that used a computer to model disease and create a vaccine is not wondering if computers make the world better.
Our propensity as a society to buy garbage quality new stuff rather than good quality used stuff is frustrating.

Tech savvy folks know they can find a fully competent, user-serviceable used computer for basic use on eBay for under $200, but Joe Blow goes to Walmart or Best Buy and only has the choice of a crappy $300 computer or a good $1000 computer, both new.

The impact on the environment alone of trashing or recycling things that can be refurbished and reused is staggering.
That's still 10-20x the cost plus the financial and other costs of the prescription services.

The problem is taking something that people have found deep benefit from, criminalizing it, and then reintroducing it at a profit for a designated monopoly.

I thought I was slowing down while I was doing a boring contract job. I wondered what my future rate of decline might be. Luckily it turned out just to be the mind-numbing job and things snapped back after it. Things are not the same, I don't have the same ability to consume vast information continuously like when I was young, but it more than pays off in that I know what to pay attention to.

Since then, I've been playing Go. It's both a game I enjoy and it's supposed to help maintain brain function late into life. Also "82-Year-Old Proves You're Never Too Old to Code"

If a thought like this crosses your mind, consider that 'now' is the best time to do things and get on with them. Keep doing things that matter to you or make you happy and look after your health. Other distractions are a waste of time and energy.
I've played Factorio in the past and am playing Satisfactorio right now. I generally don't code at home or have any side projects.

Let's do some introspection as to why I prefer playing these games over coding at work:

1. Games are designed in a way, that speaks to intrinsic human values. For instance, in Factorio, the local Fauna wants to kill me. I have to build and design my base accordingly or will I'll perish. My work in contrast, is far removed from intrinsic human values.

2. Games are designed to be accessible, with every step yielding rewards right away.

2.1. Coding in an enterprise environment is full of complex task, which have to be broken down first.

2.2. Games such as Factorio increase complexity of task later on, but you always utilize mechanics you've already mastered.

2.3. Task in enterprise environments tend to always require learning new knowledge first (business domain, existing code base etc.) before being able to solve it.

2.4. Games allow me to start from scratch. Existing code bases, which I didn't build myself, require me to invest quit some time before I can even start achieving my task.

2.5. Often, these existing code bases require me to learn new frameworks. Games teach new skills/tools in seconds or minutes. Frameworks tend to require hours or days to digest.

3. Games provide visual feedback. My labor results in visible feedback inside the (virtual) world. Accomplishing a coding task tends to not result in any feedback (I do mostly backend). If there is feedback, it's normally in text form and of negative format (error logs).

4. In general, feedback in games is unambiguous, clearly tells you what is happening. No debugging. No frustration.

When I actually know everything that is required to solve a task and can concentrate on achieving the task in the best way, that's the moment I'm having fun. But normally, there is so much I don't know, tools I can use but have not mastered, that it feels like a mess. Even if you believe you have everything, reality tends throw some roadblocks along the way.

Now, why don't I code at home and do side projects?

That's in my first point. There is just nothing I could use coding for that solves problems I care about (intrinsic human goals). Even if I know how to write the next Facebook, I wouldn't do it because I really don't care. Well, there are some code solvable things I consider interesting, but they are out of scope in terms of my resources and abilities. Also, the way along would properly still suck for the most part, once it gets serious.

Right now, I'm learning some Math in my free time. Quit enjoyable, gives me new insights in how everything works. I tend not to have that feeling why learning new frameworks / programming languages. New insights are pleasurable to me, tech stuff just doesn't tell me anything interesting about the world.

Maybe some of you who don't feel the same can understand people like me a bit better (not saying that all non side project people have the same reasons).
