This problem holds a special place in my heart.

When I first discovered PE* I checked the latest available problem, which was 202 that week. I remember thinking at the time that it was impossible to solve.

Fast forward a couple of years and a lot of solved PE problems. I took another go at 202 and I finally figured it out. The feeling of accomplishment I felt then...

*through an xkcd comic (https://xkcd.com/353/). The alt text mentions 20 small problems, which are problems from PE (IIRC this was specified in the now-defunct xkcd blog)

By learning code I mean Learning curve. You need to be able to code a little bit at a minimum to use Spark effectively even if a lot of the time you can just go with the SQL interface it isn't actually a SQL database under the surface so that can be a bit misleading if you dont know what's going on.
If you are talking about the main link, I know it is not the New Yorker. I was talking about it as an example because you can bypass almost all of them with the same method. Medium has a way to prevent that I guess.
I would suppose that they don’t “know” they just feel compelled.

There are dragon flies that migrate from India to Africa. It takes three generations to complete the round trip. So how do they know? It must be just a feeling.

I guess that a long time ago when India and Aftrica were adjacent parts of Gondwana land, the migration must have been quite short. But as the continents drifted apart the dragoon flies had to adapt to the longer route.
I don't know how much this type of bird weighs, but I imagine 5g for the tracker is a small percentage of its overall weight
A line scanner, like the proposed LIDAR implemention. We use line scanners for paper. You could certainly put a line scanner behind a conventional lens but it would feel kind of weird to "waste" an entire dimension of the lenses projection qualities. Would there be opportunities for design compromises favoring one direction over the other? (I'm thinking of the weird eyes we find in flight animals like sheep that need full horizon perception more than point of interest focus)
> the sound glitches out randomly

Edge case: white noise generator.

I’ve been looking for a small, wired and preferably powered external speaker for travel to provide louder and better quality sound masking than the tiny speaker in the phone. There are a million little Bluetooth speakers out there but the random inverted hiccups (sudden silence then resume) wake me up every time. I’m sure it’s the Bluetooth because it doesn’t happen when I use the phone speaker.

I carry a 1st gen iPhone SE for wired audio, so I guess now it’s basically an iPod.

Edit: Well, looks like there’s some stuff on eBay I didn’t see in previous searches. Retro 2000s stuff. I can roll the dice for £5 plus shipping. Use case is still relevant.
Learning to Break Deep Perceptual Hashing: The Use Case NeuralHash
It's easier to start in Python because you don't need to run dotnet new. Same with Java, you can just run java program.java and it works.

I think the dotnet approach is definitely preferable for real projects, though. If you want to get a script done in Python then that's quick and easy, but if you need to manage dependencies, you run into the exact same pattern.

Whether it's cargo new, python -m venv ., npm init or whatever incantation Java developers use, all these toolsets are pretty much equivalent. With IDE support (Visual Studio is great, VS Code works) the entire experience becomes much better.

You can't run a quick "helloworld.cs" without creating a project, but I don't see that as a problem per se. In practice, C# isn't built for scripting so it doesn't make sense to optimise the toolchain for anything but a project approach. If you want dotnet scripts, run Powershell, that's what it's good for.

The most annoying part about dotnet is the setup, specifically ensuring that telemetry is off. Microsoft insists on an opt-out, and leaves it up to you to figure out where to put the environment variable to disable their stalking. Other projects such as Flutter have the same problem.

>>Those 10 families don’t pay nearly enough in taxes to cover the cost of infrastructure maintenance.

I dont think you can objectively say that is true given that road maintenance is one of the least costly things a government does, and the less densely p;populated the less maintenance is done to that road sometimes none at all

That further assumes that the road in those areas is maintained by the government this is also not universally true, there are plenty of housing additions that have HOA's where the HOA is responsible for the road maintenance

Also in almost 100% of cases the developer creating the subdivision is responsible for the infrastructure costs to build said subdivision and also often has to pay to improve infrastructure leading into the new subdivision
Interesting. I just tried logging in from PopOS. No issues. Does it only affect FreeBSD?

I tried to do a similar thing with a single actuator frisbee. The goal would be a frisbee with a single fin could fly anywhere when launched out of some high power launcher.

The goal was to make a single-use aircraft which could go anywhere in a city for under $1. By making the aircraft unpowered and under 250g, lots of regulations no longer apply, and it becomes practical to use them to deliver small items.

The fin was actuated by a 10 cent microcontroller using a ultra low cost GPS and light sensor (for sun position), powered for up to 2 minutes by a coin cell.

The challenge was that it seems gyroscopic effects means that if a frisbee has lift and moves forward in the air, it will always see a (very slow) turning moment that requires a massive fin to counteract. The end result is the frisbee eventually turns to vertical and falls out of the air.

My prototype could still land gently anywhere in a football field when thrown by hand, which I was pretty pleased with, and had a BOM under $1!

If anyone has any ideas to make this not happen, I'd like to hear them.

We will never get around replacing old industrial interfaces like Modbus, because there are simply too many and because people still use them in new applications because better the devil you know.

Still we can use gateways and tools to expose the data to newer better options like OPC UA:

TL,DR: Unregulated business optimized towards size instead of continuous flow of goods and boom-busted transport infra-structure.

This is my largest gripe with dotnet. It seems to have been taken over by the front-end web dev types who have done so much damage elsewhere, and are on a crusade to spread their questionable practices.

The churn is getting too fast as they start to get out from under the shadow of continued compatibility with legacy 4.X dotnet. When languages move this fast, the library and tooling ecosystems cannot keep up and you lose one of the greatest advantages that C# had possessed.
rustup is not a third-party tool. It allows you to install any number of Rust toolchains for any number of architectures side by side (be it stable or nightly).
If they're actually boomers, they likely have some kind of social network in their area, they have habits, they have families relatively close, etc. Actual boomers are close to 70yo and that's not the age, where many are ready for a life change. 3x the house in some coastal town they have no meaningful connection to is not going to appeal to a lot of them.
There are literally hundreds of threads with this topic on the Web. Most of them contain the same standard references which IMO are not always the best for people without much mathematical maturity and wishing to learn from first principles. That said, here are my recommendations for them (pdfs of almost all are available online and they can also be purchased cheaply as used books);

* 1) Functions and Graphs and 2) The Method of Coordinates by I.M.Gelfand et. al. - These give you the basics on functions and how to visualize them which is crucial for understanding.

* Introductory Logic and Sets for Computer Scientists by Nimal Nissanke - Nice succinct introduction to various required topics for Comp. Sci.

* Compared To What?: Introduction to the Analysis of Algorithms by Gregory Rawlins - This is a classic book which takes you by hand and walks you through Algorithm Analysis and the reqd. mathematics. You will find this more approachable than most other text books and well worth a study.

* How to Think about Algorithms by Jeff Edmonds - Practical techniques without too much mathematical formalism.

* Data Structure Techniques by Thomas Standish - A Classic text; good adjunct to more modern texts.

* Advanced Data Structures by Peter Brass - Nice succinct text but not necessarily "advanced".

One final point; try to get a Algorithms and Data Structures book with code in the language with which you are most familiar. That way you understand the mapping from "Abstract Algorithm" to "Concrete Language Implementation" which is not always trivial.

Sounds like you don't have a good fit. Sealed buds should not have much room to 'go deeper' when properly seated.

> there isn’t a single problem above that occurs when using wires

These last two have nothing to do with wires, just the fit for a particular model?
This trendoid is so caught up with fashion movements and countermovements that they can't see the obvious truth: wired earbuds are cheap, deliver good sound without further compression artifacts or just plain cutting out due to body interference, and do not need their own batteries that need to be charged. Their simplicity also makes them relatively durable. An excellent value proposition for music on the go.
It's very practical.

Like all government projects you can't look at what's better. But what's better that the government can do. What government's choose to do is yet to be decided here. But if it's not this within this sort of energy area, it will be worse. They won't be building nuclear power plants instead.

The title is fake news. The article describes a small subset of the unvaccinated, or does the author believe that 33% of Germans for example are remotely like the people he mocks?

Poor writing, poor content.
It folds into a small storage tube, is lightweight, has good autonomy, makes little noise, and safely autogyrates to the ground on failure. If you could somehow add a camera and stabilise it, it could make an excellent search drone for search / rescue / military ops.
An unsurprising turn of events and the whole reason why Meta is in such a hurry. In fact, I have said this before already [0] and this article summarises what Meta plans to challenge Apple with, and the unattractiveness of the App Store to games companies will start to show when the metaverse is implemented by anyone who detests the App Store taxes; Microsoft, Epic Games, Netflix are notable companies involved.

This is where we are heading and smart-glasses with AR capabilities, cryptocurrencies with the so-called hype of 'web3' and the metaverse are technologies going to be involved in this of course.

Interesting aspect of the whole story seems to be institutional forgetfulness.

People who made laws in 1919 knew why certain laws were made. 60 years later almost all of them were dead and people in power never experienced the issues earlier laws successfully prevent, so they did not consider them important.

That's good in some cases - nobody today considers God's mandation of kings, because people who did believe it are dead for centuries.

In other cases, it is bad.
I did. I tried Rider and continued to use VS when I was programming on Windows. On Linux I use Rider (though I'm mostly off. Net stuff now). Reason for using VS is because I like it's UI (like the colour scheme more) and I think there are at times issues with resolving dependency issues like nuget stuff (which is what my colleague told me who is a fulltime rider user but fires up VS rarely to resolve them). I haven't tried things like parallel stack watches, debugging dlls and remote debugging. I just liked these things the way they are in VS. Though I'd rank Rider higher than VS since it runs on Linux.
> You’ve completely missed the point.

I don't understand your point because it is nonsense: magnetite was named after Magnes [1] and Pliny wrote about him and his discovery two thousand years ago. The most credible alternatives for the etymology of "magnetite" are Magnesia ad Sipylum (Manisa, TY) or Magnesia, GR, all of which existed long before the concepts of ferro- or electro-magnetism were described.

Either way, eurocentrism is the only reason you associate the word "magne-{whatever}" with the physical phenomenon.

Magnes/Manisa/Magnesia => magnetite => more than a millenium of development in physics and language => magnetism => you associating "magnetite" with "magnetic".

All words are made up.

Yeah. Apparently, it's pretty common to lock your rear leg when sitting down after a sprint. This is... not advisable on a track bike, and one of the things that needs to be trained out of riders in the track class.
This is just pivoting. In this case zooming uses interpolation which "has the potential to introduce false information" exactly as you mentioned. It using only the available data doesn't mean that interpolation can't go wrong. So what if it's not AI?

And yes, it's so well understood that the prosecution had no idea of what's going on, claiming that it's "common sense" that it works just like a magnifying glass, which is simply wrong. Using bilinear (or bicubic) interpolation makes the edges of an image blurrier, especially when you're zooming in as much as they did on low-quality footage.

Pain captures our attention, negativity feeds pain.

It makes sense: pay attention to your body if you're injuring yourself, and stop moving forward if you keep injuring yourself blindly-unskillfully moving forward in life continuing to injure yourself (and likely others). And the reason negativity feeds pain seems to be at least two-fold: everything in the body is connected and so emotional pain uses at least some of the same pathways as physical pain, and this is perhaps how or where the mind-body connection interfaces - being able to read off eachother via biofeedback loop; think a negative thought that stresses the body, the body tightens causing discomfort that then stresses the body-mind - and the reverse: learning to visualize an infinitely fast beam of healing light encompassing you and forcing its way through whole being as part of self-directed positive reinforcement visualization practice; in part this is a practice of getting as much of your mind active and flowing at once, which can be tough from a longtime stagnant-depressed mind due to suppressed or repressed feelings or sensations or unprocessed trauma.

TL;DR - Mind-body: "Pay attention to me or I'm going to force you to [learn why you're in pain, how to heal it, and how to stop from continuing to hurt from it]!"

I watched a video recently by a reviewer who had taken 1000 photos with both a Pixel 6 and iPhone 13 Pro. The difference was really quite striking, the Pixel 6 was much better at handling faces of different skin colours. This appears to be handled computationally, by detecting faces in the frame and then adjusting appropriately.

It may be the longest distance recorded for a continual flight by any land bird, but it's not an extraordinary performance.

For instance, common swifts can flight continuously for months. They obviously accumulate a huge distance during this time, even when they're not migrating. They live in Eurasia, from Lisbon to Vladivostok. And they winter in Africa, south of Congo. I think Vladivostok-Harare is a longer trip than Alaska-Australia, but it's probably hard to put sensors on small birds during their migration.
Well to help address his concerns, the newest version of dotnet had a much simplified set of project types to choose from
Very few languages throw away syntax or features. Python 3 is one that tried, and it took almost a decade for people to switch. C++ famously clings on to old features for a long as possible. Only a tiny amount of things have ever been removed from the language such as trigraphs.

It’s referenced in this article but the book “The Box” about the history of container ship is an absolutely great read.

Just like in e.g. programming 'design principles' are called principles, not 'hard design rules all of which you must strive to follow to the letter' I'm pretty sure the author's intention is for these 10 things to be interpreted like the former, not the latter (also see sibling comments).
It is not magic, but, as other posters alluded, sometimes it can be merely an educated guess. It is hard to accept a life changing verdict based on a guess.. even if it is an educated one.

So no, each time a given technique is used, the way it works has to be explained so that a decision based on facts of the case is made.

Thats not my recollection of the era. VB was was widely scorned but it was incredibly productive. At my workplace at the time, when smalltalk collapsed as a viable dev environment, it was largely replaced with VB pointing at the sybase databases we had.

The smalltalkers scoffed, but the speed the VB guys got things done killed everything else. I ended up moving to a team that built a distributed trading system on DCOM, c++ and VB and while the tech wasn't lovable, it sure worked better than corba and java.

Its easy to forget what a monster VB was. Java took forever to mature in comparison. That websphere nonsense was a huge distraction for people who just wanted a crud app.
