Think of marketing as "letting people who might use/buy your product that it exists."

You can't buy it if you have no idea it exists, right?

So how do you get the word out to the potential duatomers? You can read traction (the book), or just ask gemini/perplexity where you should advertise to find them.

"The pier has found big wins by making the whole truck-and-cargo flow less “wait your turn,” and more “keep it moving” with the addition of green lanes for ZEVs, tighter gate operations, and by pairing electrified equipment and its superior uptime with new, better rail and yard coordination."

This is basically PR from the truck company. Electric trucks allowed them to rejigger their procedures but there's nothing inherent in the trucks themselves that did that.

Electrek is a fanboy blog and will post anything that casts electric xyz in a good light. It's fun to read but yeah, it is what it is.

Have you heard the good news about regulatory capture?

Probably not if you're one of the public.

Imagine how the world would look if the EU mandated rs-232c ports on all devices. Or 3.5" headphone jacks. Or the use of D batteries for all electronics. How about ms-dos compatibility?

The software has real software engineers working on it instead of researchers.

Remember when people were arguing about whether to use mmap? What a ridiculous argument.

At some point someone will figure out how to tile the weights and the memory requirements will drop again.

The structure of most residential construction in the US is standardized. Foundation (or slab), wood framing, etc. There are different levels of quality, but codes and standards mean that standardization is the norm.

It's fun, but testing has become more of a PITA. When I write code I test and understand each piece. With AI generated code I need to figure out how it works and why it isn't working.

New comment by mannyv in "What we learned from a 22-Day storage bug (and how we fixed it)"

mannyv — Sat, 14 Mar 2026 00:30:21 +0000

Oh, never mind - yeah, by using the access logs of segments you can effectively anticipate and pre-encode when you need to. And once the hls or cmaf stabilizes you can just encode one resolution. And the player will tell you it wants to move up or down, so you can trigger the encode it wants.

It's interesting your customers want the video immediately; ours don't care about that. But you guys can really build your manifest files and encode immediately, since you're making those mezzanine files.

Then the encoded files are basically a cache that you can evict whenever.

How long did it take you guys to prove that design out?

But can you still seek on a video that's being instantly transcoded? To be honest I don't know if anyone does that except YouTube, and it jumps to the time so theoretically you have about a second or two when the request comes into pull the file and start encoding. It sounds like the mezzanine file is chunked, so the time to pull it down is pretty fast.

Since it's your own player you can hint to the backend.

Do you dynamically generate the manifests too? Or do things get transcoded on request?

Why bother transcoding on the fly? Storage is cheaper than CPU and the work it takes to determine what needs encoding is excessive.

It implies that you guys are generating the playlists on the fly, tracking the client requests, then feeding that over to your transcoder - which then needs to get the original, seek, and transcode. Why bother?

The correct question is: from whom?

When I was in finance there was a question whether US debt would crowd out other debt instruments. The answer, obviously, is "no." There seems to be an unlimited appetite for zero-risk debt, which makes no sense.

It can. Not sure what AI you're using, but Gemini outputs great bash. Of course you need to test it.

You do have to make sure to tell it what platform you're using, because things like MacOS have different CLIs than Linux.

This actually is easy to do with terraform and shared infrastructure; you don't need an AI in the loop.

Who hasn't accidentally deleted a resource because that property triggers a resource delete/create instead of an update?

It would help if it was obvious what the key fields were. But for some reason docs usually don't tell you.
