Most modern JavaScript UI frameworks boast Reactivity, but have you ever wondered what that means exactly?

In my opinion, Reactivity is largely responsible for making modern frontend development unintuitive to outsiders.

This blog post explains what Reactivity is, and how it manifested in the frontend development world today.

You might find this interesting if you're: a frontend dev unfamiliar with the concept, a non-frontend dev interested in frontend, or just curious what Reactivity is!

One recommended approach to improving an application’s performance is caching.

I understand that Exact Cover is a problem where you want to select a subset of rows from a binary matrix such that each column contains exactly one '1'. What specific constraints need to be included in the matrix to ensure that the solution adheres to the rules of Sudoku (e.g., unique numbers in rows, columns, and subgrids)? provide a simple example of a Sudoku puzzle and its corresponding Exact Cover representation may be 3x3 sudoku puzzle for example ? I tried reading the Wikipedia article and various links, but I couldn't understand Exact Cover, even though I am familiar with the DLX structure.

Threat actors are utilizing an attack called "Revival Hijack," where they register new PyPi projects using the names of previously deleted packages to conduct supply chain attacks.

The technique "could be used to hijack 22K existing PyPI packages and subsequently lead to hundreds of thousands of malicious package downloads," the researchers say.

If you ever install python software or libraries using pip install then you need to be aware of this. Since PyPI is allowing re-use of project names when a project is deleted, any python project that isn't being actively maintained could potentially have fallen victim to this issue, if it happened to depend on a package that was later deleted by its author.

This means installing legacy python code is no longer safe. You will need to check every single dependency manually to verify that it is safe.

Hopefully, actively maintained projects will notice if this happens to them, but it still isn't guaranteed. This makes me feel very uneasy installing software from PyPI, and it's not the first time this repository has been used for distributing malicious packages.

It feels completely insane to me that a software repository would allow re-use of names of deleted projects - there is so much that can go wrong with this, and very little reason to justify allowing it.

When you're on a website or an app, you look at something (a post, or a part of a UI), and your brain just starts calculating how this was made in your own language.

Like brain, stop, I'm tired, I don't need the calculations right now.

Obviously, given the subject matter, I had to let ChatGPT generate a summary for this:

The Meta Stack Overflow post discusses a policy decision regarding the use of generative AI tools, such as ChatGPT, on the platform. The key points include:

1. Ban on Generative AI: The community has decided to prohibit the use of generative AI for answering questions on Stack Overflow. This is due to concerns about the quality and reliability of AI-generated content.

2. Quality Control: The decision aims to maintain high standards for answers, as AI-generated responses may lack accuracy and context, potentially leading to misinformation.

3. Community Feedback: The policy was influenced by feedback from the community, emphasizing the importance of human expertise in providing reliable answers.

4. Future Considerations: The post suggests that while the current stance is a ban, the situation may be revisited in the future as the technology evolves.

Overall, the policy reflects a commitment to ensuring that the content on Stack Overflow remains trustworthy and valuable to its users.

What's your take on parquet?

I'm still reading into it. Why is it closely related to apache? Does inly apache push it? Meaning, if apache drops it, there'd be no interest from others to push it further?

It's published under apache hadoop license. It is a permissive license. Is there a drawback to the license?

Do you use it? When?

I assume for sharing small data, csv is sufficient. Also, I assume csv is more accessible than parquet.

And Linux isn't minimal effort. It's an operating system that demands more of you than does the commercial offerings from Microsoft and Apple. Thus, it serves as a dojo for understanding computers better. With a sensei who keeps demanding you figure problems out on your own in order to learn and level up.

...

That's why I'd love to see more developers take another look at Linux. Such that they may develop better proficiency in the basic katas of the internet. Such that they aren't scared to connect a computer to the internet without the cover of a cloud.

There are a couple I have in mind. Like many techies, I am a huge fan of RSS for content distribution and XMPP for federated communication.

The really niche one I like is S-expressions as a data format and configuration in place of json, yaml, toml, etc.

I am a big fan of Plaintext formats, although I wish markdown had a few more features like tables.

This past few weeks, Python 3.13 and the possibility to disable the GIL has seen a lot of coverage and that pushed me to dig into my own language, to see how different our approaches are.

So if you’re curious about the rambling of a pldev, that might be for you!

I'm trying to feel more comfortable using random GitHub projects, basically.

Long story short, I don't have the resources to keep any PC on for a reasonable time, so I want to make use of all the hardware I can find, I have an old iPad 4th generation lying around, I know anything related to programming becomes annoying when using a touchscreen but it's what I got, I don't mind jailbreaking it, or even have a Linux distro that actually works on (I'm fine with compiling stuff myself too)

I prefer simplicity and using the first example but I'd be happy to hear other options. Here's a few examples:

HTTP/1.1 403 POST /endpoint
{ "message": "Unauthorized access" }

HTTP/1.1 403 POST /endpoint
Unauthorized access (no json)

HTTP/1.1 403 POST /endpoint
{ "error": "Unauthorized access" }

HTTP/1.1 403 POST /endpoint
{
  "code": "UNAUTHORIZED",
  "message": "Unauthorized access",
}

HTTP/1.1 200 (🤡) POST /endpoint
{
  "error": true,
  "message": "Unauthorized access",
}

HTTP/1.1 403 POST /endpoint
{
  "status": 403,
  "code": "UNAUTHORIZED",
  "message": "Unauthorized access",
}

Or your own example.

Apologies if this is the wrong community, happy to remove and post elsewhere.

I'm essentially a beginner to programming. I know some python (made a game of hangman with ASCII art for example) but nothing more complicated than that.

I've been wanting to learn some programming, whether it's python or something else, and I think I've decided on a project I want to make (if possible?).

I aiming to make an emulation front end/GUI selector. I know there are things like RetroArch that are great, but it doesn't have access to all emulation tools (e.g. doesn't have Xbox/PS2/switch).

I'd picture just opening one program GUI that can select the "system" you want to use, then it provides a list of games.

The complexity that I can see is that even if I can run the actual emulator in a container or use a custom GUI to open the emulator it won't 1) be able to show a games list within the same GUI and 2) it won't be an easy back and forth to change emulators.

Not looking for anyone to solve the problem for me, just hoping for some advice on where to start like languages and what I should be trying to learn etc. or if it's even possible. I'm aware there's a high chance it's not!

I've got years to learn and build before my kid might use it, not in a rush.

Thanks!

Videos (part 1 and part 2) just released for public viewing this week.

Grace Hopper (December 9, 1906 – January 1, 1992) was an American computer scientist, mathematician, and United States Navy rear admiral. She was a pioneer of computer programming. Hopper was the first to devise the theory of machine-independent programming languages, and used this theory to develop the FLOW-MATIC programming language and COBOL, an early high-level programming language still in use today. She was also one of the first programmers on the Harvard Mark I computer. She is credited with writing the first computer manual, "A Manual of Operation for the Automatic Sequence Controlled Calculator."

Originally, I was going to use D, but its current WASM guideline is buried under a lot of Discord threads, all while people are lazy to touch the wiki. I need to test stuff with WASM (use for scripting in applications, not browsers).

Please NO RUST!!! While I see why functional programming is useful (I even use wasmtime as my WASM engine, which is developed in Rust), but is horribly counterproductive for game development, especially if it's opt out like in Rust.

EDIT: In the meanwhile, I've found AssemblyScript, which seems to be good for my usecase.

A judge has dismissed the majority of claims in a copyright lawsuit filed by developers against GitHub, Microsoft, and OpenAI.

The lawsuit was initiated by a group of developers in 2022 and originally made 22 claims against the companies, alleging copyright violations related to the AI-powered GitHub Copilot coding assistant.

Judge Jon Tigar’s ruling, unsealed last week, leaves only two claims standing: one accusing the companies of an open-source license violation and another alleging breach of contract. This decision marks a substantial setback for the developers who argued that GitHub Copilot, which uses OpenAI’s technology and is owned by Microsoft, unlawfully trained on their work.

...

Despite this significant ruling, the legal battle is not over. The remaining claims regarding breach of contract and open-source license violations are likely to continue through litigation.
