RecycledEle··on Hackberry-Pi_Zero – A handheld Linux terminal using Raspberry Pi Zero 2W
I wish someone would make a 5" to 7" clamshell "laptop" that runs a Linux command line and lasts forever on an internal lithium (or replaceable AA) battery.

I want the retro feel of mini laptops back when GUIs were only on $20k UNIX workstations.

RecycledEle··on Ask HN: Weirdest Computer Architecture?
Using piloted pneumatic valves as logic gates blew my mind.

If you are looking for strangeness, the 1990's to early 2000's microcontrollers had I/O ports, but every single I/O port was different. None of them had a standard so that we could (for example) plug in a 10-pin header and connect the same peripheral to any of the I/O ports on a single microcontroller, much less any microcontroller they made in a family of microcontrollers.

RecycledEle··on Why the US still needs the F-15 [video]
What if stealthy designs and coatings get replaced by active RF stealth (where the plane being targeted by the radar emits RF that makes it look like it is not there?)

Would an F15 EX with such a system be the ideal fighter for 2030?

RecycledEle··on AI crawlers need to be more respectful
I suspect the AI companies are as careless with their training as they are with their web scraping.
RecycledEle··on Ask HN: Best way to learn robotics with a 10 year old?
Find a FIRST Lego League (RLL) team for the kid.

Maybe buy Lego Mindstorms and Lego Technics for home and when the kid runs out of ideas, give them challenges like a line-following robot or a FLL course.

Then move to a FreeNove Ultimate Sarter Kit. I prefer the Arduino Uno based kits, but the ESP32 kits have their place as well.

RecycledEle··on How can I do my research as a GPU poor?
Look into buying a used Dell c410x GPU chassis (they are $200 on my local CraigsList) and a Dell R720. Then add some cheap GPUs.

For a few thousand dollars you might get some processing power.

But you will never be able to pay your electric bill.

RecycledEle··on ESA report shows unsustainable levels of orbital debris
Active debris removal is almost at the level if being an experimental technology.

If it works, and if it gets cheaper as the technology matures, it might let use remove derelict satellites before they break up into smaller pieces.

It is usually easier to remove a few thousand big pieces of trash than to remove millions of small pieces of trash.

RecycledEle··on Russia's stocks of Soviet-era weaponry are running out
All military alliances are closer to street gangs than they are to book clubs.

If everyone on my street joined an anti-mr street gang, I would be concerned.

RecycledEle··on Pac-Man on a vape: electronic cigarettes target youth as gaming devices
Sometimes a YouTube video shows an example better than I can.

I can not walk my class through a datacenter, but I can show them a video then let them play with a partial rack of servers I got in a CraigsList deal.

RecycledEle··on Where did the name "Dilbert" come from? [video]
I found a WW2-era US Navy video called "Don't Kill Your Friends!" on YouTube that called guys who ignore safety rules "Dilberts."

I'm sure the US Navy got the same from somewhere.

Does anyone know the origin of the name "Dilbert? "

RecycledEle··on 10% of Cubans left Cuba between 2022 and 2023
Noduerne, may I ask a question? I hope I do not offend you.

I know that million of white men died fighting against the Germans in WW2.

Why is it that 95% of what I hear from Jews is condemnation if white men for being NAZIs, when the majority of white men and the winning side fought against the Germans?

It seems like there should be a 60% gratitude to 40% condemnation split.

RecycledEle··on 10% of Cubans left Cuba between 2022 and 2023
I like the idea of setting an immigration quota based on how many meighborhoods overwhelmingly vote to welcome immigrants, and then requiring the immigrants to live in those neighborhoods as a condition if their immigration status.

If the immigrants enrich the community, those who welcomed them get the enrichment.

If the immigrants bring crime and disease, those who welcomes them get the crime, disease, and decreased property values.

I love solutions that work whether my views are right or wrong.

May I steal that for part of my political platform?

RecycledEle··on Pac-Man on a vape: electronic cigarettes target youth as gaming devices
If you want to get mad at someone, YouTube targets classrooms with pre roll ads of some eTHOT talking about getting high with her dad on edibles full of synthetic THC.
RecycledEle··on Pac-Man on a vape: electronic cigarettes target youth as gaming devices
Do kids know what PacMan is?

I thought that was a thing only us old people knew about.

RecycledEle··on Ask HN: People who were alive when walkmen were introduced. What was it like?
Walkmans made music possible, if you had the spare batteries.

Batteries were the limitation.

RecycledEle··on Anna’s Archive approaching 1 petabyte
A lot of their content is duplicated.

De-duping similar uploads of the same version of the same book would cut petabyte down quite a bit.

RecycledEle··on Public toilets are vanishing and that's a civic catastrophe
In Texas, fast food places almost always allow people to use their bathrooms.

The few fast food places that do not let me go without complaint get a complaint to corporate and they lose my business for a few months.

RecycledEle··on I mapped almost every USA traffic death in the 21st century
There would be unintended consequences from car helmets.

Maybe they would interfere with looking over your shoulder.

RecycledEle··on I am starting an AI+Education company
I hate to ask this, but: Has anyone ever done a study to see if this kind of education works?

I love Neal Stephenson's "The Diamond Age," but can narrative-based learning work as the main way to instruct a student?

RecycledEle··on Tell HN: your next idea should focus on aged care
The butt wiping robot may be called a bidet combined with air drying.
RecycledEle··on Oystercatchers are waging war on NYC's beach drones
> I suspect if they put the drone budget into lifeguard pay, they'd find quickly they no longer have a problem recruiting.

The problem may be Management-Class people who think it is unethical to pay above the bottom quartile in pay or to accept less than the top quartile in talent.

I believe the Management-Class is the cause of most of our problems.

I define Management-Class as people who yell at and fire people whose jobs they could never do.

RecycledEle··on Linus Torvalds says RISC-V will make the same mistakes as Arm and x86
Can someone please create an instruction set where the entire instruction set is implemented (even if in microcode) on every processor that uses that instruction set?

Have you looked at RISC-V or x64? They are messes of instruction set extensions, most of which reuse the same opcodes.

We have terabytes of disk space and gigabytes of RAM. We can afford a few extra bits in the opcode.

RecycledEle··on Bullets for sale in some US grocery stores with ammo vending machines
Do they have a drivers license that is the kind US citizens have, or do they have another form if photo ID?

In Texas, there are many variations on ID cards and Drivers Licenses. The style and color say a lot.

RecycledEle··on Destroying Russian Tanks Is Just the Start for U.S. AI Drone Autopilot
A lot of drone autopilots will use commercial, off-the-shelf (COTS) chips and software. Imagine an exploit for a common example program or for a library in a common development environment.

A state actor could build a database of ways to profile and exploit those chips and software.

Imagine hacking a drone and ordering it to return to home and drop its payload there.

We may see firewalls on drones soon, or watchdog timers that trigger a second microcontroller to take iver when the primary is hacked.

Metasploit already supports software defined radios (SDRs.)

RecycledEle··on Daylight eInk Computer
The animated web site is exhausting and distracting. It literally made me dizzy, and I do not get dizzy.

I doubt they have all the apps I need.

I stopped looking that that point.

RecycledEle··on How to validate a market with development boards and SD cards
I have rarely seen someone this happy to add friction that prevents his customers from buying his product.
RecycledEle··on AI cheating is destroying higher education
I agree.

I teach my students to use AI ethically.

I teach them that ethical use of AI is when the AI helps you learn so that when the AI is not there you are more capable.

But if using the AI as a crutch so you do not have to learn things is unethical.

RecycledEle··on Apple blog TUAW returns as an AI content farm
I wish there was a way to report inaccuracies on web sites so the maintainers of those web sites and so search engines could see the reports.

Then maybe the garbage sites would get down ranked in search engines.

RecycledEle··on Kanban vs. Scrum: What's the difference?
I just asked ChatGPT "Can you please tell me the difference in Kanban and Scrum in 2 paragraphs?" It gave me a better answer:

Kanban and Scrum are both popular Agile frameworks used to manage and improve work processes, but they have distinct differences in their approaches and practices. Kanban, originating from the Toyota Production System, focuses on visualizing work, limiting work in progress (WIP), and improving flow. It uses a continuous flow model, meaning tasks are continuously added and moved through stages such as "To Do," "In Progress," and "Done." Kanban emphasizes flexibility, allowing teams to pull work as capacity permits rather than adhering to fixed iterations. Its core principles include visualizing the workflow, managing flow, making process policies explicit, implementing feedback loops, and evolving collaboratively.

On the other hand, Scrum is a structured framework that uses fixed-length iterations called sprints, typically lasting two to four weeks. It defines specific roles such as the Scrum Master, Product Owner, and Development Team, and ceremonies like Sprint Planning, Daily Stand-ups, Sprint Reviews, and Retrospectives. Scrum emphasizes delivering a potentially shippable product increment at the end of each sprint. It promotes regular inspection and adaptation through its iterative cycles, aiming for continuous improvement and fast delivery of valuable product features. While Scrum prescribes a clear set of roles, events, and artifacts, Kanban is more flexible, allowing for the integration of its practices with other existing processes without requiring significant changes to the workflow structure.
