from what i've seen anything heavier than a URL is NOT stored directly in the blockchain. And even URLs are done sparingly and/or dynamically.

for example NFT metadata/data is often stored in IPFS & only linked to from the contract.

but confusingly some people still call data stored on IPFS "on-chain data".


I couldn't find it with a quick search, but I remember many years ago someone creating a similar scheme for storing files inside of TinyURLs.

You would run the uploader and get back a list of TinyURLs that could then be used to retrieve the files later with a downloader.

But you couldn't store too much in each URL so the resulting list could be pretty big.


This is a favorite lunch topic at work. AFAIK we stumbled on the idea ourselves, but I'm not surprised to hear it's unoriginal. Rather than a list, our design is a tree structure where leaf nodes contain data and branch nodes contain lists of tinyurls...


Someone also created a filesystem using DNS caches of others to store the files: https://news.ycombinator.com/item?id=16134041


Heyyyy thanks glad you enjoyed it! I was surprised to wake up and see this on Hacker News today.

Thought I'd comment on the video editing:

It is all pretty low tech. I use Adobe Premiere to edit and mostly just animate transform, scale, and crop effects to achieve everything. Like for the zooms you pointed out I double up a layer of the screencap and then crop and scale. It's a bit painstaking at times.

Another little part is when I do the screen recording I set my desktop background to an image with a colored box area of 1280x720. This is the area I know will be "on screen". So I have the windows I want to pull in during the video just outside this area. Then I crop to this box in editing. I think this is better looking than just capturing the whole desktop, and I like the live feel.

I'm enjoying evolving this style... I sometimes have thoughts of making some kind of gross homemade video compositing tool in JS. But I haven't gotten there yet...


Everything about this is great, I'm not a big video watcher but I just sat through that whole thing it was gold. The selfie direction flips, the interjections from you in another setting instead of chopping the video (both funny but also a nicer way to do it honestly). The concepts you're showing. All really good. Keep it up I'll be watching!


Thanks for the tips and tricks. If you ever made a video on how you make videos, I'd be first in line to watch that.

I haven't looked at Premiere since the bad old days before it traded places with Final Cut as the default choice for editing. These days, I spend most of my time on Ubuntu and use Kdenlive for my very minimal requirements.

The one thing you have that is much harder to teach is great comic timing. I suspect that it will serve you well in many aspects of your life. I don't know if you've been polishing your fast five, but if you ever have an opportunity to try your hand at standup, I'd encourage you to go for it.


Check out ShareX, it can easily capture a subset of your screen, and you can hold a modifier (I forget which) to snap to common video resolutions / aspect ratios.


Dang this is sneaky and awesome ! Great job. I'll have to remember this


Looks like it's adding a canvas element to the divs and positioning it to line up.


Ah yes I missed the var canvas line and just presumed the code was getting a context on the selected div instead, a feature I didn't know was possible (it isn't).

The canvas declaration is staring right at me now that I review it again. That's life...



Totally agree !

I basically learned to code on a TI-83.

The fact that it's a mobile programming platform is a huge plus as well. I haven't seen anything comparable on smart phones. And a touch screen just can't compete with that keyboard. Even if it is a weird layout.

Underrated device !


I knew that you could program on a TI-83. But after I was exposed to QBasic on a 586 PC-clone machine, diddling around on a calculator held very little interest. Nothing will ever be able to surpass a real keyboard and mouse.


I had both as a teenager, but ended up spending far more time programming in TI-Basic, only because I could take my TI-83 everywhere. I even got in trouble a few times for trying to sneak it in my suit jacket to formal-ish occasions I didn’t want to be at. And Z80 assembly programming offered an incredibly compelling allure (though I never got past simple programs full of ROM calls).


Ah but you can !

I bought a Thinkpad T420 last year and put OS X on it using this amazing guide: http://www.insanelymac.com/forum/topic/285678-lenovo-thinkpa...

Works great :]


Reminds me of back in the day when I had a hackintosh desktop running 10.6; really the last good OS X version. Everything since that I haven't really liked.


I found ammo in boxes next to the guns. But I didn't at first see it as ammo, I thought it was some kind of barrier and moved on. So maybe it's a matter of making that more obviously ammo looking ? Like a stack of bullets ?


Seconded. It took me a while until I noticed that the small colored squares are ammo - I only realized it after I noticed a label popping up and disappearing as I moved over them.

It's something I made a few weeks ago for fun to discover STL files on GitHub.

Let me know what you think :]
