Final #COLDCARD Q tease before shipping.
None of the clients could take the 120mb vid upload ๐

While weโre on the subject, is this the only workaround for larger mb uploads to #Nostr
Trying to get a video on here. And I donโt use other Social Media anymore ๐ฅบ
You literally have your own web servers. Why do you need to upload your video to a client??? ๐
https://satellite.earth/cdn would have taken it.
Saved for next time
Here you go bro I got it for you. https://video.nostr.build/6f8a523c654642f374f0d536f216c4d9ff1fce7eb6d224cbe8913bf75f0895ad.mp4
How did you do it?
Did you compress the file, or find another way to work around the file size cap?
Probably better encoding. Canโt check what both versions are using but there are a ton of techniques you can use to reduce the file size using something like ffmpeg.
Most content on the web is absurdly high quality in my opinion. And most people arenโt consuming it from a 40 inch screen where they can notice. Now what I did was a pretty silly hack job to just cut it down significantly. I dropped 2 or 3 frames per second cut the width and height in pixels down significantly and then used whatever compression my video compression app uses. So I can see the reduction in quality a bit on my phone. But as most of us are using 5 inch or less screens to do most of our scrolling itโs a fine trade off in my opinion.
Think about the infrastructure here. It hurts my heart a little to know that the default resolution and quality settings being sent to image and video hosting sites, and the data consumption up and down every time someone reads a image or watches a video is sufficient for an 4K 60 inch screen. Or the publishing quality 30 inch photo graph.
Could be nice if the clients could hook in a compression library with some sane defaults for mobile viewing. It could decrease the data requirements for everyone and improve user experience by being a lighter lift for any client trying to download and play content.
Thatโs probably because 60fps videos are smooth.
I think AV1 will make things better in that regard. AV1 encodes videos are ~30% smaller in size than HEVC and royalty free. Just like HEVC is taxing on the CPU but it should become standard as every device gets specialized extensions to decode it just as it was with HEVC.
Yeah I just scaled the image to require less pixels and compressed it. 3mb
How do y'all rationalize the closed source secure elements vulnerability. Because I would like one..๐
Thatโs very easy.
Step 1) suppose the secure element is backdoored
Step 2) stay air gapped forever
Step 3) input your own entropy from dice rolls
Step 4) after signing a transaction, verify the transaction signature on your own node before broadcasting (which I believe but am not certain is done anyway)โฆjust in case the signature is invalid and merely an attempt to disclose private key or seed or something else nefarious.
Step 5) recognize that after the above, a back doored chip can do nothing nefarious other than sign incorrectly, in which case you need a new signing device/hardware wallet.
Step 1: Don't rely on a secure element in the first place as most use cases are fine with a stateless device.
Step 2: Save a truck load of money. The end.
If you think any coldcard device is a truckload of money, you need to work harder and stack longer. Then there will come a time when such things are cheap.
But youโre right, stateless is often good enough. I treat my coldcard as stateless
Okay Mr Money Pants. I can't wait to get as rich as you so I can just burn sats just because. :)
The funny thing is, all ya gotta do is buy bitcoin and wait. The more you buy and the sooner you start waiting the better.
But youโll likely never be as rich as me. I played the fiat harvesting game well and got blessed by bitcoin long ago.
You do highlight my point thou. For the majority of plebs, hardware wallets like this, arent really needed. Even for you it's likely still a waste of sats, you're better off with something else, unless you're making regular large transactions.
How do you create a key without a proper HWW?
Itโs a convenience item. I use it in paranoid mode. But I donโt have to.
You can calculate your own private keys by hand from dice rolls, but I choose not to.
But nobody would ever disagree that minimizing trust is always safe, presuming you donโt outsmart yourself.
Our design takes that into consideration and simply do not trust any single chip alone. You could say the same about all chips in all devices.
Looks like a TI-100
Bravo nostr:npub1wu4aye7ll0lnrrg638e90sehzsgpzx5t39t3mwl05aa0d0ap08esdz3vw0. This looks awesome ๐ฅ
๐
the music is epic as well as the hw, onward
When ship?
Beautiful!
Where do I insert the SIM card?
Will check it out in Atlantis ๐
Looks great! Can't wait too play
Thats dope.
This is incredibly exciting! Cheers to the team here on the next generation ๐ค ๐ค ๐ค
Roll on pay day, canโt wait to grab one & clone it with the Mk 4 ๐
looks ๐ฅ
Is Sendina still work on Coinkite and shipping 1 CAD โโโcalculatorsโโโ and โโโmetal plate for writingโโโ?
Fucking awesome!
Can't wait...pre-ordered as soon as I saw the announcement.
The sexiest TI83 I've ever seen. Thank you. Going to do so much math on this!
can't wait, and the satslink!! ๐คค ๐
