Bias of a data set is when it doesn't reflect the true underlying distribution of nature.

So a face corpus with only white faces doesn't reflect the diversity of faces one encounters in the world.

With that said, unbiasing data is extremely difficult because the true distribution of things is unknown and sometimes subjective. The visual images you would encounter as a human from birth to death growing up in a first world country would be very different from that of a drone's video camera. Are we really sure that imagenet should be K% animals and not K/2% animals? And if you train a machine learning algorithm on every possible image with every possible pixel, it will just learn noise.
A very popular analog computer patchable with 4mm banana jacks was the Comdyna GP-6. I went down a rabbit hole of reverse engineering it from photos and schematics years ago in order to build a version that would fit in a 3U panel for Eurorack modular synth interfacing. Never finished it, but the total BOM was... well, not much. The panel was going to cost more than the board+opamps+passives. I wanted to buy a real Comdyna but I remember the cheapest I found one for sale was ~$700 and I thought that was expensive. Not so much when you compare it to this unit which is housed in just open PCBs and a much smaller format.

If you are a student and want to learn a bit more about how operational amplifiers, resistors, and capacitors alone can solve differential equations... you can get an educational license for Matlab for nothing and Simulink can emulate all the analog circuitry you want and more.

Another approach might be using the Eurorack simulation software VCV Rack - If there isn't an set of modules you can install that do basic gain, integrators, multipliers, comparators, etc then it would be very easy for someone to write one.
Had bad experience blocking some sites from working completely. Especially social media. It was years ago how are things now?
I daresay China and the other nations would disagree with your assessment as to where the axe should fall. Your list--and I believe all such lists--has a strong subjective bias. I have no doubt there is a user on Tencent and a user on VK who have the US and Western Europe as candidates.

I do suspect AI can provide a future Alexander with a tool to solve such a Gordian knot. ML controlling chaotic systems such as double or triple pendulums demonstrates how intrinsically unstable systems can be managed. Imagine the power and ability of 8 billion coordinated people.
It was clear by March 2020 when the passengers on the Diamond Princess were all locked down in their cabins and COVID didn't care at all, managing to infect people all over the ship essentially at random. This is only possible if it is able to spread long distances via the air; if transmission were droplet or surface based that would have ended the outbreak immediately.

Please don't cite the CDC for anything, they're utterly discredited.
> I'm glad you survived, but I'm having trouble imagining how this was only "incompetence".

The business kept going and is still operating. Why it was incompetence is because they had no formal HR function or Legal function at the company at that time, and so just mishandled things because they didn't know what they were doing from an HR/Legal perspective. I believe this has since been resolved. I don't want to go into more details, but as one of the harmed parties, I am satisfied it was not malicious and merely an oversight due to ignorance.
The claim was that among those problems, energy would become more expensive. My counter point is that energy is actually becoming cheaper and while we’re at it, less carbon intensive.

Cheap energy is a great way to solve a lot of the other problems. And lower carbon energy can chip away at the root cause.
Not being from Washington myself, which is it?
The question is why your belief is so widespread. The battery pack in a Telsa S or X model was literally 7000 flashlight batteries in a metal box. The newer standard-range pack from the 3 and Y models has thousands of larger cylindrical cells that won't literally fit in standard flashlight but which are nevertheless off-the-shelf Panasonic catalog batteries.

Speaking as an Apollo user for five years, the official app is just terrible. From big problems like confusing/inconsistent navigation and missing video and text formatting options to annoyances like slow/delayed animations and janky scrolling, there's just a huge lack of thought or polish in Reddit's app.

I think Reddit is just embarrassed that one guy can make an app that's so, so, soooo much better than their slow, cluttered, ugly, expensive app.

You are just handing over _everything_ to a company which has proven they can't be trusted. Why? For a _zombie game_?! Just to be clear, I'm not against games or head-mounted displays.

Googler, opinions merely my own:

Google's monorepo and tooling for changes across the entire repo make it possible and common to fix entire classes of mistakes at once. Bad patterns lingering in copy/paste is not an issue in practice due to a combination of such changes and linter presubmits that identify and flag any recurrence in the future.
What amazes me is that some people choose to continue 100% masking for various reasons, but wear ineffective or poor fitting cloth masks or generic flat surgical masks with huge gaps, when comfortable and effective N95s from name brands are readily and inexpensively available.

It's not a product announcement. It's a description of research that appears to have been integrated into their internal day to day tooling.

Do you also complain about e.g. research papers that are published on systems that you can't use?
I have one pretending to be a grandfather clock (it used drive a servo that rang a physical chime via a little motor driver controlled by GPIO, but the servos would burn out every year or so, now instead cron just plays some .ogg files of a clock striking). But for straight-up servers, wouldn't a bunch of docker containers (or even some shell scripts and cron) cover many of those other uses? I tend to think of the Pi as a sort of 'physical container' that gets me a full OS (with networking, package mgmt etc.) which can be great if you only need one thing in one place, but I also have a little fanless NUC-alike running a bunch of containers.
It isn't just a matter of just optimal-packing the material, you have to figure out the thermal runaway problem. That's the big argument between prismatic vs cylindrical cells, anyway. Prisms do a good job of filling a block of space but they don't provide nearly the structural integrity to contain, isolate, and direct the venting of a misbehaving cell.
It takes some time to decode, but I can grab- for example- this 259k JPEG: http://placekitten.com/3840/2160

And display it from the microSD card with this code: https://gist.github.com/Gadgetoid/0b8e352e377135d743338c9483...

As more or less demonstrated by this example: https://github.com/pimoroni/pimoroni-pico/blob/main/micropyt...

Decoding is done via Larry Bank's JPEGDEC: https://github.com/bitbank2/JPEGDEC

It uses roughly 20k RAM to provide the necessary buffers both for decoding JPEGs into blocks which are passed to a drawing routine that handles copying the data into the display RAM buffer (on our larger Inky display this is backed by PSRAM). I don't believe there's a hard limit to the size of the JPEGs you can display. The main bottlenecks are decoding time and the relatively limited scaling options: FULL, HALF, QUARTER, EIGHTH.

This aside, the authors solution is actually quite elegant. As long as you have control over the image pipeline there's no real reason to encumber the device with handling large (both in bytes and pixel dimensions) files. You'll also get much better dithering results writing your own routine to convert files from JPG to the raw 4-bits per pixel format for the display. Our built-in dithering is just a plain ordered dither matrix and, while quaint and retro, it leaves much to be desired visually.

If you're trying to use a public API you can also make GitHub actions automate the whole image conversion process and publish the results to GitHub pages. This works great for, for example, the daily XKCD, serving both to reformat the strip for the display, credit the author, extract the "alt" text and avoid excess requests to the origin. Eg: https://pimoroni.github.io/feed2image/xkcd-800x480-daily.jpg. Though the astute will notice I still opted for jpeg in this case.

Main thing is supporting the platform. Second is the longer posts without having to do split threads. I think the "edit" implementation and the delayed posting is very broken to say the least.

As to making fun of someone willing to pay to support a given system, I'm not sure that's at all productive. At that point, should probably not even be using said system in the first place. That doesn't mean I agree with every decision, or every direction, but do find it's a bit better than before overall.
What you are doing is trying to get the benefits of claiming that you are open source, without truly making it open source.
What is open source is well known in the industry. If you search on google what open source mean - you will find that you don't fit the criteria.
It would be much more ethical to truthfully say what you are doing. And don't get me wrong, what you are doing is still great.
The trickest part I see there is you're going to need some sort of midi input and associated parsing to actually make the thing playable.

Or are you thinking of building a keyboard as well.

I suppose there are probably MIDI to CV modules out there one could source.

What now? Established trends have been regularly violated over thousands of years.

> It's not surprising that the human race has survived for this long - we always find ways to adapt, no matter what challenges history throws at us. This is what distinguishes us (and I suspect will always do) from the machines.

You know what would count as an adaptation? Large fractions of population becoming immiserated and either dying off or living in poverty at the margins.

Mere survival is the wrong metric.

This is great, but keep in mind this is like a third derivative metric. North America is way behind China in number of batteries owned, batteries produced, and factories being built. This is just the growth rate of factories being built.

> my understanding is users can't replace iMessage with another messaging app.

To be precise there is one "Messaging" app, that automagically uses iMessage (blue bubbles) instead of SMS (green bubbles) whenever possible. One can turn off iMessage in the settings, which will probably lead to your iPhone rejecting iMessages, making other iPhones only send SMS to you and also make your iPhone only send SMS. Whether that toggle prevents receiving and processing of malicious, invisible iMessages is an entirely different question.
Your idea of 100e6 people with a high standard of living is a fantasy.

High standards of living are a product of billions of people, many in much lower standards of living. The regression to progress of having much fewer people is another huge problem.

And it's a very weirdly urgent take when demographic collapse is going to handle a lot of this for us anyway.
Reddit doesn't really have content creators, just content reposters.
No, I agree. I don't expect it would or even should happen, but if it did I would be very interested.
There's a global battery shortage. Tesla will put whatever cells it can into their packs in the coming years, including soft 'pouch' cells.
Nerds with too much disposable income who will buy this, spend maybe 20 minutes total and then put it away to collect dust.

But think back to the 1970s when jetpacks were first demonstrated. Today we're all flying around on them; the automobile, aviation, and flame-retardant headgear industries have been radically altered, and humanity will never be the same again.
New Hurricane Forecasts Could Predict Terrifying Explosive Intensification
How can you imply a woman past menopause might possibly want sex?? And who would be willing to satisfy that desire, anyway??

Actually, it's probably a bad idea to combine them because the body's response to hormones is so variable. Keep them as separate pills so you can tweak the balance easier.

Why is that amazing? Masking is a social phenomenon at this point. It's about showing other people what sort of person you are, not about the mask itself.

This reminds me of the Uzebox [1], a video game console based on an ATMega644, but the RP2040 in this looks far more powerful at a glance. How far could this realistically be pushed?

It is a good idea in theory, but the timeline is tricky. It isn't realistic to get something up and running before Reddit cuts them off, and by the time they could the users would have moved on.
18650 and 21700 (aka 2170) are standard cylindrical shapes for EV battery cells, so the comparison to AAs falls flat. Tesla has launched the 4680 cell, and the industry may move in that direction. Batteries are custom on a per car basis, in the same way that remote controls are all shaped uniquely, but almost all of them will take either AAs or CR2032 cells.

Pouch and "blade" cells are much less standard, and are also used in a bunch of EVs, like GM's Ultium platform.

Following through the examples in the article, the battery factories are all also including battery cell manufacturing either onsite or nearby. (The BMW example has "an agreement to source next generation lithium-ion battery cells from Envision AESC, which will build a new plant in the state." The others are combo cell+battery factories, like Tesla does.)
Any chance you have a recommendation of newsreader for android?
My humble opinion. First, I would make sure that they are actually doing something bad, since you do not describe their behaviour but your feelings about them. It is possible that a person is genuinely trying to explain something, and they are not good communicators, or they are massive experts and come off as arrogant. Sometimes we expect people to address us in a certain way, based on hierarchy at a company/age/job title. Some people do not care much for such things, and with a certain combination, misunderstandings can arise, where no harm is intended.

Assuming the behaviour is bad, it probably steams from insecurity. Some people see life as a competition, or getting a best score as an objective, or is the main way they have learned to get appreciation (from parents, teachers, bosses). Think Lisa, from the Simpsons.

I would also avoid framing everything in terms of "have you done this before", like other commenters are recommending. It is more important if someone can back their words on the present, that an appeal to authority. (have you used Angular 3.1.2.3 before?, have you studied economics?, etc.). Arguments should be evaluated on their own, even if for practical reasons in real life we use heuristics based on experience.

Finally, I do not think the right term for this is being (over)smart. Depending on the behaviour it could be lacking social skills, being arrogant, condescending, etc.

Solving Differential Equations with Matrices (2016)
For years now, I’ve been using a query builder that supports migrations and basic, non-instanced “model” functions that represent the cases of fetching and modifying data as required by my application.

This allows me to have as much to data access as I need in easy-to-stub methods, without an overly opinionated ORM stepping in. The query builder does its job to simply build queries I ask of it and I don’t have to worry about a gigantic piece of code liability. I really tend to avoid using a library for everything these days and using libraries that do far too much (and if I do, I limit exposure by wrapping calls to it in functions I create).

Another mistake IMHO was that they accepted too many "dictionary characters", i.e. the ones only seen once or twice in some obscure dictionary -- they often had explanations like "an obscure form of [common character]".
But your equipment for handling water is almost certainly going to measure things in terms of volume/minute, where the volume unit will not be acre-feet. Perhaps it's gallons. Or hogsheads.

The acre-foot is a useful measure only for certain scales of volumes, but there's a need to convert between small and large scales of volumes all the time.

If we didn't have the metric system, sure, the acre-foot makes sense to use. And in the metric system, perhaps people will occasionally talk in terms of hectare-cm instead of liters or m^3 (I don't know enough about non-US water systems to know what they typically use). But regardless of liters or m^3 or hectare-cm, these can all be converted by moving a decimal point rather than multiplication or division with multiple significant figures.

We have a better system, we have just chosen not to use it.

> Many (I don’t have an exact number) clinical practice guidelines are based on expert opinion or observational studies, and are completely valid/evidence-based (it’s just weak evidence).

A big problem is that humans have a preference for action, and a dislike of waiting for information.

Many flawed guidelines are based on a desire to act even in the absence of evidence of benefit.

"Primum non nocere" is probably the most accepted but least respected tenant of good medical practice.

Any modern smartphone will have several days of battery life, if not more, if you use it as a dumb phone (WiFi & mobile data turned off, only using it for calls & SMS). My Galaxy S5 (~8 years old now?) passively discharged at 1% per day with WiFi & data disabled.
Another pair of PIO blocks (and two more DMA channels) is my desire. I think a lot of people would love to see a (slightly more expensive) variant with more uncommitted GPIOs.

My pet projects with the Pico and clones involve interfacing with an 8-bit processor, and the RP2040 just doesn’t expose enough pins for the full data, address, and control busses AND actually doing something interesting with the outside world.

Another dedicated USB PHY peripheral would also be great, a lot of people lose a PIO block to adding a second USB port. Obviously this also shows the power of PIO, but it’s nice to be able to reserve those blocks for more obscure physical things.

I bet a lot of people would like more analog pins, the Teensy provides a lot more, for example.

So, it's depends how they do that. In 2022, Apple seemed to buy all the Apple stock they used for RSUs in the open market. So, absolutely not in that case.

But they don't have to do that. They could issue the shares for RSUs. If they issue new shares (either to sell to the market or to use for RSUs) then the market cap directly influences how much they can generate in work or cash from such a transaction.
