teruakohatu··on $2 WeAct Display FS adds a 0.96-inch USB information display to your computer
People have had this dream for probably close to 20 years (since Kindle v1).

And yet it still seems out of reach beyond going with a full hdmi eink display.

The closest I have found is the M5Stack 4.7” eink display with built in esp32 and lipo battery.

teruakohatu··on Statistical Physics with R: Ising Model with Monte Carlo
> most data scientists

It's hard to generalise for all data scientists everywhere, but that is not my experience.

Data transformation (80% of the job) is very functional and so objects systems don't matter much.

But when you are training neural nets in Python you are probably using a framework of some type. Torch in R looks very object orientation'y .

The issue is not that object orientation is fundamentally needed for data science, but when you install a random object orientated R library you get a random R object system or pseudo-object system that needs to be reasoned about.

It is a pity R didn't just ditch object systems or adopt a limited simple system like Lua's table approach.

teruakohatu··on Statistical Physics with R: Ising Model with Monte Carlo
I love and use R, but it never became the dominant ML in part because it has three (or more) different object systems and many libraries sort of use their own style.

This makes it seem a bit disjointed, in a way that other languages don’t.

The R community should have anointed one object system and made tidyverse a core part of R.

All that said, R is fantastic and the depth of libraries is extensive. Libs are often written by the original researchers that develop the method. At some academic institutions an R package is counted as a paper.

teruakohatu··on Interactive map of Paul's first century travels in Roman world
His main privilege was that petty local rulers were more reluctant to persecute him than they would a non-citizen.

Seneca’s brother, most well known as the recipient of Seneca’s letters, was one such judge who dismissed the charges against him when he found out that he was a citizen.

teruakohatu··on Show HN: Clearcam – Add AI object detection to your IP CCTV cameras
Try building up a method iteratively. Start by calculating the speed of a car as it crosses the camera frame.

Then try calculating the speed between two points (in car length in front of and a car length behind the stop sign).

Then set a threshold for how fast is too fast for a car to realistically go between those two points without stopping. Get notified with a video snippet when a car is above this threshold. Adjust the threshold based on the videos you are capturing.

It won’t work if your object detection is not running at your camera framerate.

teruakohatu··on Trees on city streets cope with drought by drinking from leaky pipes
I wouldn’t be too sad. There are lots of companies offering ML leak detection. Most or many are using fibre optics and using them to detect changes in temperature or noise along the line. Sample the signal for period of time and run it through a model and you have leak detection.
teruakohatu··on The West is bored to death
> Just a few short years ago, everyone was advised to “learn to code”, regardless of where their real interests might lie. Yet now, we are told, this is one area where large language models already excel. Will some share of the hundreds of billions of dollars being invested into Stem be reallocated toward rescuing the humanities – the one set of disciplines whose value does not depend entirely on unforeseeable macroeconomic contingencies? We shouldn’t hold our breath.

This is an odd statement, and probably reflects the authors own anxieties.

teruakohatu··on The Minecraft Code (2024) [video]
> Telling people they should not try and crack something is kind of like the Streisand effect.

More like a reverse-streisand effect. They were honest about the contents of the file, it was Minecraft 1.0 and not interesting, but the community didn't accept the explanation.

Wow, I thought it was an official app. Now I wonder what telemetry or even conversation data I have just sent offsite.

As others have said, this is a giant red flag.

teruakohatu··on Streaming services are driving viewers back to piracy
> She opens Netflix, and ⅔ of the films have now "expired"

I have given up saving Netflix titles in advance of travel because this has happened to me too many times. What is bizarre is you can only "download" them a certain number of times, despite being expired. So I now cannot download some shows ever again.

Nobody loses money if I cache a Netflix show to my device. The limitation is bizarre.

I should have clarified, you can’t for subdomains on a non-enterprise account.
teruakohatu··on Nginx introduces native support for ACME protocol
This has blown my mind. Its been a constant source of frustration since Cloudflare stubbornly refuses to allow non-enterprise accounts to have a seperate key per zone. The thread requesting it is a masterclass in passive aggressiveness:

teruakohatu··on Historical Tech Tree
Rope was around long before the wick. It seems conceivable that rope shavings or pieces or old rope were an easy way to start a fire.

This was then used with oil to make an even better fire starter or means of transferring fire. Eventually someone realises that a rope soaking in oil is easily lit and sustains a flame.

teruakohatu··on Flipper Zero dark web firmware bypasses rolling code security
> Who actually asked for keyless entry?

Probably the vast majority of consumers?

There is no reason why keyless entry cannot be more secure than a physical key, other than incompetence.

The cars stolen in New Zealand are usually, as you say, cars that are known to be easy to enter and drive away. Even then, they break a window. But I have also heard of break-ins at night targeting certain high-end cars and going as far as gaining entry to a garage.

teruakohatu··on OpenAI's new open-source model is basically Phi-5
> researchers will be frantically trying to fine-tune it to remove the safety guardrails.

It is a really weak excuse. They are more likely to take a reputation hit for having silly guardrails than for having someone to remove them.

Imagine if Bill Gates decided not to release MS Paint in 1985 because someone could have drawn something offensive with it.

> Get a subscription and use claude code

I find the token/credit restrictions on Opus to be near useless even when using Claude Code. I only ever switch to it so get another model's take on the issue. Five minutes of use and I have hit the limit.

teruakohatu··on Cable bacteria are living batteries
It allows the lower cells in the cable to perform cellular respiration by transferring electrons up the chain.

This benefits the top cells in the chain by making the mud less hospitable to competitors. So the bottom cells and top cells all win.

teruakohatu··on Positron – A next-generation data science IDE
> Thanks for your thoughts on the license; we know that it's FRAUGHT, for sure

There is no doubt that your company maintains a lot of high quality open source code.

But in this case Posit is re-licensing Open Source code, with a "source available" license.

Posit is free to help itself to VSCodium, but not the other way around.

I do hope Posit will one day reconsider this.

teruakohatu··on Positron – A next-generation data science IDE
Can it be run through a web browser like VS Code and RStudio?

Why did you relicense it under Elastic License 2.0 from VSCode’s MIT?

A better alternative would be proprietary extensions under a different license like Microsoft does.

teruakohatu··on What went wrong inside recalled Anker PowerCore 10000 power banks?
The RC (Radio Controlled) deal with this all the time. They often wreck huge lipo batteries so they have techniques to discharge them in safe manner. Google or search RC forums.

teruakohatu··on Cognition (Devin AI) to Acquire Windsurf

You are welcomed to your point of view, but for me while one agent is finding an obscure bug, I have another agent optimising or refactoring, while I am working on something else. Its hard to believe I am deluded in thinking I am spending more time on a task.

I think the research does highlight that training is important. I don't throws devs agents and expect them to be productive.

CC has some integration with VSC it is not all or nothing.

Do you have a citation for this?

It might be at a loss, but I don’t think it is that extravagant.

teruakohatu··on MCP-B: A Protocol for AI Browser Automation
I had that opinion too.

You can ask an agent to browse a web page and click a button etc. They will work out how to use a browser automation library.

But it’s not worth the cost, time spent waiting or the inconsistency between implementations.

MCP just offloads that overload, much like how they can use bash tools when they are quite capable of writing an implementation of grep etc.
