cwoolfe··on The EdTech Revolution Has Failed
From what I've seen, they are trying to steer the ship of education towards the dominant political ideology in the area. Or they may be tasked with fixing a perceived problem in the existing bureaucracy.

This is possible! https://www.techlockdown.com/

There are plenty of companies successfully doing allow-list only filters. At home for focus: https://gertrude.app/ At work for security: https://adamnet.works/

yes, I see a lot of value in this approach, especially for ADHD learners (who represent about 10% of the student population). Imagine if the only thing a kid could access on their school computer was the thing they were supposed to be doing? How much would that help focus? On MacBooks, you can use https://gertrude.app/ to enforce this allow-list only approach, which has proven very beneficial for homeschool students.

Our district uses Light Speed Content Filter. It uses a web proxy with tls decryption to read the page content and block certain videos flagged by the AI. Works way better than our previous system. That being said, now the issue is a matter of distractions. They can watch "appropriate" videos, but they just watch at inappropriate times...like during class or at lunch. As a parent, I take an allow-list only approach to YouTube. they can only watch individual videos/channels I select. everything else is blocked.

Yes! For this reason our school district has stopped sending them home in the lower grades. Most parents are thankful.

We use Safe Vision to access YouTube by allow-list only https://safe.vision/

Not only are we paying teachers worse than we used to, we are actually spending more on education! The scandal is the addition of more useless Administrator positions. https://x.com/TCCRI/status/1760792700771533084

Yeah! I used Dragon Box in my high school math class back in 2015. Loved it!
cwoolfe··on No evidence social media time is correlated with teen mental health problems
Ok, now let's see the study that shows it is beneficial to teen mental health.

I quit it and my mental health improved. Many others in a controlled study found the same effect.

Alcott and colleagues (2020) randomly assigned 2743 adults to either deactivate their Facebook accounts for one month or not. This study also found that deactivation significantly improved subjective well-being and that “80% of the treatment group agreed that deactivation was good for them.” The treatment group was also more likely to report using Facebook less and having uninstalled the app from their phones post-experiment.

Finally, this strikes me as the same playbook that big tobacco used in the 90s. "Doubt is our product," Michaels quotes a cigarette executive as saying, "since it is the best means of competing with the 'body of fact' that exists in the minds of the general public.

cwoolfe··on AWS CEO: In 2 years...it's possible that most developers are not coding
"It just means that each of us has to get more in tune with what our customers need and what the actual end thing is that we're going to try to go build," Garman said, "because that's going to be more and more of what the work is as opposed to sitting down and actually writing code."
cwoolfe··on Australia starts peanut allergy treatment for babies
Nuts are a very good and healthy natural snack; it's a shame they are banned by most daycares and schools now. It would be great if this became so common they could be allowed again. Without nuts...what do we have instead? Chips. granola-bars. These are highly processed foods that have other issues. Raisins or apples maybe? but they are mostly sugar. None of these options have healthy fat & protein like nuts do. What healthy snacks do you feed your children?
cwoolfe··on Flux: Open-source text-to-image model with 12B parameters
Hey, great work over at fal.ai to run this on your infrastructure and for building in a free $2 in credits to try before buying. For those thinking of running this at home, I'll save you the trouble. Black Forest Flux did not run easily on my Apple Silicon MacBook at this time. (Please let me know if you have gotten this to run for you on similar hardware.) Specifically, it falls back to using CPU which is very slow. Changing device to 'mps' causes error "BFloat16 is not supported on MPS"
cwoolfe··on How to validate a market with development boards and SD cards
Yes! And don't forget to somehow encrypt the data on your SD cards, or do a check-in with the cloud to activate, otherwise your customers can make copies and give away all your software for free!
cwoolfe··on Making AI better at math tutoring
Hard-coding explanations does seem like the way to go here. It's what researchers at Carnegie Mellon did back in 1984 with demonstrated success. See: Intelligent tutoring Systems: The ACT Project https://www.youtube.com/watch?v=boDH_pW14B0 My question is, if we've had intelligent math tutoring demonstrating success in real classrooms since 1984, then why haven't we been actually using them to help teach math?
cwoolfe··on The Mythical Non-Roboticist: Wouldn't it be great if everyone could do robotics?
Well said. "Don’t design for amorphous groups. If you can’t name three real people (that you have talked to) that your API is for, then you are designing for an amorphous group and only amorphous people will like your API."
cwoolfe··on Daylight Computer – New 60fps e-paper tablet
Great work! I've spent the last year listening to parents, teachers, and administrators voice their dreams and issues with technology and I think what you all have done here could add a lot of value in the education (EdTech) market in a few years. Educational e-ink tablets are being tested in China this year: https://goodereader.com/blog/tablet-slates/aoc-launches-educ...
cwoolfe··on Does light have an infinite lifetime?
"The light shines in the darkness, and the darkness can never extinguish it.

God sent a man, John the Baptist, to tell about the light so that everyone might believe because of his testimony. John himself was not the light; he was simply a witness to tell about the light. The one who is the true light, who gives light to everyone, was coming into the world.

He came into the very world he created, but the world didn’t recognize him. He came to his own people, and even they rejected him. But to all who believed him and accepted him, he gave the right to become children of God."(John 1:5-12)

"God is light." (1John 1:5)
cwoolfe··on MacBook charger teardown: The surprising complexity inside Apple's power adapter (2015)
Am I slowly damaging my 2020 M1 MacBook by charging it with a cheap 5V 1A USB-A to USB-C charger at night? What's the actual risk here?
cwoolfe··on Show HN: A user-friendly UI for viewing and editing Markdown files
The app isn't part of the developer program so when you try to open the app, MacOS says "You should move this app to the trash" haha! Workaround via running: xattr -c /Applications/Marker.app

cwoolfe··on Heat Pumps Take on Cold Climates
As someone who switched to a heat pump recently, you should know "your mileage may vary." Don't confuse physical efficiency for cost efficiency. In many places, natural gas is still more cost efficient, even if it isn't as efficient in terms of physics.
cwoolfe··on Ask HN: How many of you Apple developers still use Objective C?
I used Obj-C professionally for about 2 years and Swift professionally for about 2 years. I have a slight preference for Swift. I've been doing mobile dev on iOS and Android since 2012 and there have been a lot of language changes and programming paradigm shifts. I think it's become more accessible for new devs. For me, I don't think the time and headache to learn the new ways really had a lot of benefit on the end product. Maybe in larger software shops it did.
cwoolfe··on Better Call GPT: Comparing large language models against lawyers [pdf]
Where can someone upload a contract and ask the AI questions about it in a secure and private way? It's my understanding that most people and organizations aren't able to do this because it isn't private.
cwoolfe··on The failure of self-checkout technology
It can still work; just needs a better implementation.
cwoolfe··on Omg.lol: An Oasis on the Internet
How did you get cian.lol? Why isn't it cian.omg.lol?
cwoolfe··on I think I need to go lie down
The site requires an OpenAI Key and describes doing this as "risky but cool" ... What data would be exposed by sharing my key?
cwoolfe··on EU's concealment of secret 'expert list' on CSAM regulation is maladministration
great pdf! thanks for sharing!
cwoolfe··on EU's concealment of secret 'expert list' on CSAM regulation is maladministration
The idea is to combat it on on children's devices so that they are not able to produce CSAM without their parents knowing about it. The proposed solution doesn't combat on the recipient side.
