If only they had some sort of marketplace to be able to sell them off at a reasonable price.
zarify··on AI in schools – The choice we keep making
Hahah, smart boards. I remember pushing back hard against my school on those. The fact they evolved into short throw projectors that occasionally have ok touch monitoring is a win, even if it took a bunch of $5-10k surfaces that no one could draw on, but inevitably ended up with a few whiteboard marker smudges to get there.

Open gradebooks are amazing. You just need to have school leadership that sets realistic expectations with students and parents and backs up their teachers rather than caving to helicopter parents. I've had nothing but good feedback from parents and students about timeliness and transparency on marking feedback. Standardised testing on the other hand is goddamned menace that has done more to damage the value of assessment than transparency ever has. The value of open gradebooks is the feedback, not the numbers.

AI in schools feels like more of a fait accompli. Who provides most of the software infrastructure to schools? Microsoft and Google. Who is busy stuffing AI into all the things? Oh look, it's Microsoft and Google.

zarify··on Ask HN: What is one simple thing LLMs are insanely bad at?
Determining important from human speech. I’ve had a few summaries from meetings I’ve been involved in and there’s always been a real mismatch from what was actually focused on and how it comes across in the summary.
zarify··on Screen viewing time from age 1 to 8 years and subsequent academic performance
Sounds like it's just focused on shows and games from the description in the paper:

> At ages 1 and 1.5 years, which was conducted in a subsample, parents were asked to report the average amount of time that the child spent daily on television (TV) on weekdays and weekends within the past month. This was collected in 2010 to 2011 when TV was the primary source of screen viewing time for 97% of Singaporean families [38]. At ages 2, 3 and 6 years, parents were asked to report the amount of time, in 5-min increments, their child spent using screens on weekdays and weekend days. Three types of devices were considered separately: (1) TV and TV-related games consoles; (2) computers (desktop or laptop); and (3) hand-held devices including tablets, smartphones, and hand-held games consoles. At age 8 years, parents were asked to report on their child’s time spent sitting or lying down while watching screens on the most recent weekday (school days) and on the most recent Saturday and Sunday. Four types of devices/media were considered separately: (1) watching videos on a TV (TV programs, DVDs, Blu-ray); (2) watching videos or playing games on computers; (3) watching videos or playing games on tablets or smartphones; and (4) playing video games on consoles.

We’re having this sort of conversation at the school that I work at, which serves remote communities and other disadvantaged students. One of our states is currently making noise about reducing “screen time” for schools without much distinction about what it involves.

And here’s us, an online only school that serves kids that otherwise wouldn’t be able to access education at all or some types of classes at best, left wondering where that might leave us if our state decides to zombie its way into similar policy decisions.

Edit: Downvotes for pointing out that government policies without nuance around what "screen time" means hurts kids who have no alternative education options, apparently?

zarify··on People Who Will Thrive in the AI Age
Feels like there’s a lot of projection going on there.

I’ve worked with a lot of professionals over the years who chose to work part time (and have done myself too). Various reasons, but mostly it boiled down to valuing their time and wellbeing more than grinding full time.

The thing about “living standards” is, like many standards they change depending on your priorities.

zarify··on Building a real-time AI tutor for 5-year-olds
AI aside, I think the biggest thing we could do is stop thinking about education as a profit centre. We’re not multiplying humanity if we’re only doing it for the fraction that can afford it.

Edit: Having more of a look I see you’re making this freemium, which is a good thing.

zarify··on The Xteink X4 E-Ink Reader
I bought one of these and I quite like it. Form factor is nice, transfer is a bit rough around the edges but serviceable.

Pretty sure my credit card got harvested from either them or the website purchase though

zarify··on I automated my job (and it made me a better leader)
I think there’s a lot of value in some of this (and as the owner of a somewhat spicy brain I relate to the desire for processes that help), but it feels like at least some of this (c|sh)ould be scripted and not LLM’d.

I’ve been watching some of the GitHub App promos, and it feels like because you have an app with access that knows how to agent, that’s the first method within reach, even if it isn’t necessarily the best one.

zarify··on Xiaomi MiMo-v2.5 Series API Permanent Price Reduction Up to 99%
Funny, I had the opposite experience with MiniMax and Mimo when using OpenCode. MiniMax got stuck with looping through broken tool calls all the time and MiMo just powered through things and for the most part just worked.
zarify··on San Francisco Solved Metro Vandalism with One Neat Trick
Sounds like yet another thing that makes life harder for the unbanked, the homeless etc.
zarify··on Ask HN: What tech purchase did you regret even though reviews were great?
This is the sort of thing that makes me worry about my solar inverter, battery etc. so much remote management stuffed into these things.
zarify··on Ask HN: How would you set up a child’s first Linux computer?
I recently installed Ubuntu on a little Geekom mini PC for my 6 and 8 year olds to share. So far my 6 yo isn’t too into it, but her older sister mostly uses it for the games I’ve put onto it through Epic and Steam and programming using MakeCode, mostly for Arcade (https://arcade.makecode.com) (I have a couple of micro:bit-based handheld shields) and more recently getting into the awesomely simple networking that the micro:bit provides (https://makecode.microbit.org).

Since the micro:bit requires some file management for programming them, that’s been a good entry point to the file system.

zarify··on Unbound Academy hasn’t replaced teachers with AI
> - the fact that in another role they would have to work 25% more (50 weeks per year instead of 40 weeks per year)

Heh. I left teaching for three years to work in the private sector and the "25% more work" was honestly the best work life balance I've had in 20 years.

zarify··on Solar and battery to make up 81% of new US electric-generating capacity in 2024
Ah, it was probably me hearing about Texas and then extrapolating that to the rest of the US. Probably not a great idea on my part. Thanks for setting me straight :)
zarify··on Solar and battery to make up 81% of new US electric-generating capacity in 2024
Ultimately how useful is the high uptake in individual states? My understanding was that the US had a lot of weirdness going on about provision of utilities over state lines.

(Mind you here in Oz I think we have our own state politics involved, but I guess at least we have fewer states )

zarify··on Gemini can't show me the fastest way to copy memory in C# because it's unethical
Gemini refused to provide any suggestions about implementing a serial connection in a non-standard way for some hardware I own because I ran the risk of “damaging my hardware” or producing buggy code.

Copilot pulled something similar on me when I asked for some assistance with some other third party code for the same hardware - presented a fading out message (article paywall style) with some ethical AI disclaimer. Thought this one was particularly strange - almost like a request from either the third party or the original manufacturer.

zarify··on Why we should end the data economy
There have been a number of instances here in .au where centralised location/health/etc data has been misused (stalking, checking out potential dates, domestic abuse or aiding domestic abusers) through inappropriate access. I doubt we're unique.

I'd argue that it doesn't need to be "Joe Q. Public", because companies are made up of Joe Q. Publics.

zarify··on Teaching our five year old to code by cheating
I teach kids to code (plus other techy stuff) for a living.

Some kids love my robotics classes using MakeCode or MicroPython. Some kids love my data science classes with Python and SQL (I doubt anyone loves the Excel formula :P). Some kids love writing games in Scratch or MakeCode Arcade. Some love writing MakeCode in Minecraft EE. The one thing they all have in common is there are always kids who get turned off by the environment we're using.

zarify··on Ask HN: What's the worst piece of software you use everyday?
Some of my students tell me I talk too fast, so it can be helpful for them to review content, and I've had quite a few students with varying degrees of hearing impairment. Pretty useful in my field.
zarify··on Ask HN: What's the worst piece of software you use everyday?
The screen sharing one has bitten me a couple of times. I record live classes for students, and we've had occasions when someone who was away goes back to the video and it's a black screen with me nattering away as if they can see it :/

That said, apart from the shitty embedding support and their channel management, I REALLY like Stream and using it for a video lesson platform. The captioning is quite good even for my fast talking, Aussie accent and jargon.

zarify··on Ask HN: What's the worst piece of software you use everyday?
I've use Teams every day in education for a couple of years now.

My favourite file access "feature" of Teams (I verified it was in fact working as intended, at least until the pandemic and the warts started getting more obvious) was that class teams had read/write access by default for all files in a team. This meant every student in a class team could modify what you uploaded by default. Of course fixing this required opening up the team in Sharepoint and fiddling with permissions, totally something every teacher is expected to figure out right?

Not really a software feature, but their update rollout style is awful as well. Announce features 4-8 weeks in advance of rolling out patches. Inconsistent rollouts, so my home desktop might have the latest feature patch, but my work laptop won't (I was around 4 weeks out of sync at one point). Manual checking for updates won't apply the latest patches. Meanwhile their consultants in education are crowing about all the new features or bug fixes.

I actually like some of the feature set, and it's very useful in an educational setting now they've brought some of the new features online (3 months later than would have been useful for the pandemic lockdown in my part of the world, but oh well), but enough frustrating elements that I'm constantly supporting workmates in its use.

zarify··on MIT to no longer consider SAT subject tests in admissions decisions
Alternatively it could be objection to numerous examples of somewhat arbitrary standardised testing which takes over student education to the exclusion of pretty much anything else, limiting a lot of the creativity and enjoyment students might otherwise take part it.

But that's just my cynical educator's view.

zarify··on Ask HN: Best Static Site Builder?
I quite like Publii. It’s more of a CMS that builds a static site, and is nice from a “don’t want to fiddle with template languages” perspective. Will push to different services (I use GitHub Pages) as well as just generate a folder to sync yourself.
zarify··on Ask HN: What will become possible by 2025 in your field of expertise?
I’ve been using Thonny with my students which has some basic feedback about errors and possible solutions, which isn’t bad (as well as variable inspection, although that gets a bit tedious with larger programs).
zarify··on The Pixel 4’s face unlock works on sleeping people
Authentication != authorisation.

The bank manager is still authentically the bank manager, gun or not.

zarify··on LastPass bug leaks credentials from previous site
There was this example from 2017. https://freedom-to-tinker.com/2017/12/27/no-boundaries-for-u...

I seem to remember reading about similar stuff done elsewhere, but don't remember the details (or apparently a useful search term :P).

zarify··on What Netflix’s ‘Great Hack’ Gets Wrong About Cambridge Analytica
Pretty sure the abuse is what happens to the victims, not the perpetrators.

(Not any sort of implication about whoever Mr Rogers is [I'm not an American], but man the phrasing of this sentence stuck at me.)

zarify··on I work in an Amazon warehouse in West Sacramento
I can believe someone taking 10 sick days off a year and no more. You take the paid time off if you're sick without much hesitation, and after that you weigh up whether you're sick enough to cost you a day's pay.

People should use their sick leave - that's what it's for. This "no raise for using sick leave" argument is no better than the overwork culture that's been discussed at length lately.

Mind you, I'm not an engineer, I'm a teacher. Unless it's seriously contagious or I'm basically unable to function I don't tend to use my sick leave because it's more work to prepare lessons for a replacement teacher than it is to come to work and teach.

zarify··on Macintosh Forks
The new folios work really well on your lap (and are quite pleasant to type on as well, once you get over the emoji key and lack of escape key).

I paired a bluetooth mouse to mine on the iPadOS beta and have been using it for work for a couple of weeks. Much nicer to use than my work-supplied Surface Pro which isn't saying much, since they are awful at using on your lap).
