HeyLaughingBoy··on Stringman, an $800 open-source room scale gripper robot
So, you fear someone else making it "useful in certain environments?"

Probably sell more of them as expensive cat toys.

I was actually just thinking about something like this this morning. Mainly because I was idly wondering if the kinematics would work with just 3 supporting cables. Intuitively, it seems like it should, but I haven't bothered to research it yet.

Anyone?

I don't think the CoCo I could be expanded beyond 32k since that's as many address lines as they brought out to the bus. When I worked for Alpha Products/Colorware, we sold a MacPaint clone for the CoCo2 that required 64k.

CoCo3 came with 128k out the box though.

I never knew there was an expansion pack for floppies.

At my first job, we used Model I's for testing hardware. Since we were live-plugging I/O boards into the bus to test quickly, we'd occasionally kill one (they were surprisingly robust, though). No matter: there was a shelf full of them because the owner bought a pallet at a garage sale.

If I had known there was a floppy for it, I'd have asked for one. Our BASIC test code had to be typed back in if there was a power failure, or we had to get a "new" one off the shelf.

Are you serious? That's fkn brilliant!

Amazon didn't exist at that time (or was probably still only selling books). Digi-Key still had a $25 minimum order. RS was pretty much the only game in town if you were a high schooler with a small allowance.

OTOH, some items were surprisingly cheap. A couple years after college, I had a small business running out of a spare bedroom making temperature monitors and there was a shielded audio cable with connector that I used for the sensor. Radio Shack's price was about $1.50 each but all the "real" parts houses were at least 5x that.

Few things impress me more than someone using shell sizes correctly :-)

HeyLaughingBoy··on I didn't know I was lacking in Vitamin D until I collapsed at work
I did controller software for blood (plasma) analysis instruments for over a decade. Vitamin D was actually one of the harder analytes to process. Now that I'm writing this, I don't even remember what was so hard about it. I vaguely remember issues with the reagents clumping together and being harder to separate before they could be properly mixed with the sample.
HeyLaughingBoy··on I didn't know I was lacking in Vitamin D until I collapsed at work
There's been some talk (I haven't followed it) that autism spectrum disorders are linked to insufficient Vitamin D.

Here in MN, we have a very large population of Somali immigrants. Their children, born in MN, have a higher prevalence of autism than the ones born in Somalia. To the extent that the community has begun to call it "the Minnesota disease."

HeyLaughingBoy··on Spain train crash: 'At least 10 dead' in high-speed collision
I was responding to the comment that there wasn't a sensor available that would work.

I worked on a system that sat in the railroad right-of-way and by necessity had to detect an oncoming train from at least half a mile away due to our response time. We were aware that the railroad already had the data on where the trains were, but for RR safety, there was no way that we could get access to that, so we had to place our own sensor next to the track.

You raise an interesting point that if you're near a switching point, you need to know the point's position to determine if there's a potential collision. For my system, it was placed far enough away so that was not an issue: if we detected a train, we knew it was coming our way.

HeyLaughingBoy··on Spain train crash: 'At least 10 dead' in high-speed collision
So you detect them miles away. It's a real-time analysis problem: assign a latency equal to the longest time required to react and that's the time you have to detect an oncoming train.

HeyLaughingBoy··on Whatever Happened to Fire Escapes
I generally don't start a fire in the fireplace unless the temperature is below 10F. I'm not hanging out around the firepit at that temperature.

The horses will probably go to a rescue. We run one and take in and rehome lots of horses that have been seized for mistreatment via court order.
HeyLaughingBoy··on Banks are now trying to offload the AI data center debt they just underwrote
I remember getting a mortgage and the loan officer saying that there was a 100% possibility that the loan would be sold within 60 days of closing.
HeyLaughingBoy··on Amazon pushes up prices across the Internet
That's not just happening on Amazon, tho. Hang out on /r/smallbusiness and you'll find tons of tiny retailers asking for help on how to deal with the same problem.
HeyLaughingBoy··on Amazon pushes up prices across the Internet
Yep, and I live in a rural area about 10 miles outside town. Amazon Prime was reliably within 2 days until a couple years ago when they opened a fulfillment center about 20 miles away. Now I often see an item I'm buying as available within hours. I basically use Amazon Prime as a way to avoid having to drive everywhere. Ease of returns, Prime Video, etc., are just icing on the cake.

Highlight the fact that it's a 501(c)(3) on the website. Being a non-profit opens up opportunities for donations from large corporations and applying for government grants. I notice that you have a PayPal Donate button. IIRC, PayPal has a specific payment structure for nonprofits.

You could say that about a lot of crimes, but that's not how it works.
HeyLaughingBoy··on Vibecoding isn't as fun as writing code by hand
Most software is purchased or built by businesses for their internal needs. Are you a business?

> how many orchestras will be needed?

Many more. There isn't a fixed amount of software needed in the world: the amount will expand to fit the capacity. There's a reason it's been consistently difficult to find good programmers: there's more work than the existing population can handle. By expanding to use AI, I expect that the amount of programming work will grow, not shrink. However, the amount of programmers may decline.

HeyLaughingBoy··on Vibecoding isn't as fun as writing code by hand
It's funny you say that because just this morning I was thinking about my first job and remembering how amazing it was that I was actually getting paid to do the thing that I did for fun in my spare time.
HeyLaughingBoy··on Vibecoding isn't as fun as writing code by hand
yes.

> lot of first time mothers are rather mediocre

I had a hen who was sitting on a clutch of eggs this summer. Did everything right: kept them warm, turned them regularly, etc.

Then one hatched and she promptly lost interest in the rest, leaving them to die.
