Interesting tidbit, the original definition for Celsius set 0 as boiling and 100 as freezing. It was swapped in 1743. https://en.wikipedia.org/wiki/Celsius

ESP-IDF is super friendly, I was amazed how easy it was to get it set up and configured compared to my experience with some other embedded toolchains I've used before.

Just login as "root", no password. I was amazed how familiar it felt.

There are some affordable (relatively) 10 gig switches nowadays, though they are based on SFPs so you have to factor that into the price too. Mikrotik sells a 4 port SFP+ switch for about $150.

It would be interesting to see how that would work and what sort of unique features Apple would offer in a proper enterprise product, but I'm struggling to imagine Apple returning to that market in earnest. Even Xserve was not really a

They don't, at least not conductive ones. Volterra drills through holes but they aren't conductive. They recommend using rivets or less preferred is filling them with conductive ink and baking, but that's a huge pain and I im

Yep, my first experience with programming was TI-BASIC and all I had to go on was the TI-83 manual. I used a lot of GOTO until I figured out how loops worked.

This is possible with PiHole too by setting some firewall rules. Example for Ubiquiti: https://www.derekseaman.com/2019/10/redirect-hard-coded-dns-...

It's not a few billion dollars, it's hundreds , and probably decades before it pays off. Private investors have dabbled with alternative approaches to fusion that promise lower costs, but none of them have really panned out and i

How DIY are you looking for? The Open Book reader is a pretty neat project. https://github.com/joeycastillo/The-Open-Book

by gh02t 6y ago
Comparing the raw numbers in terms of cost I don't think quite gives the right picture, you have to think about scale of investment. Whole (large) towns and biggest-in-the-world facilities were raised and the brightest minds committed.

The blast chamber that you chuck nuclear weapons in is not a good analogy, I suspect we don't know how to build such a thing that has a net positive energy yield when you factor in how much energy it takes to build a thermonuclear we

Stars and fusion nuclear weapons exist. And I'm only half joking. The energy yield of fusion is there and the basic physics are pretty well understood. Progress has been agonizingly slow but steady. We generally understand what needs t

by gh02t 6y ago
I'm a nuclear engineer working at a laboratory known for fusion research. Commercial fusion power at any scale is not happening by 2030. 2040 or 2050 are more realistic and may still be a stretch.

They basically do that internally already, there's not much point. The power usage is offset if you're primarily using them during the winter in that the energy used is all converted to heat. It's not gonna be as efficient as

No worries, that was plenty of detail, thank you. I fully understand working on things you can't discuss the specifics of.

Out of curiosity, what about this particular project made you opt for CircuitPython? Was it something targeting hobbyists and wanting to allow them to tinker with it? I'm not trying to put it down because I like CircuitPython, but I wo

by gh02t 6y ago
Same in my neck of the woods (engineering R&D). Python is very popular and everybody I know is using Python 3 unless they are supporting an outdated codebase, where they are usually in process of migrating.

Sure, but I don't think this is "inspiration" so much as blatant, wholesale copying, at least if the screenshots and copy on the page are representative. ElementaryOS borrows heavily from Apple style without being an outright

by gh02t 6y ago
I don't want to be too hard on this project, but is it really "design-forward" when it's blatantly and explicitly copying the look and feel of iOS/iPadOS? Originality seems like an important component of good design

A couple of their top of the line switches can actually do layer 3 switching. I haven't actually tried that, but the docs don't mention it requiring a USG so I don't think it does.

by gh02t 6y ago
Yes. As I said, I do that myself with a pfSense firewall/router into Unifi switches and APs with multiple VLANs and routing between them. I've also done it with an Edgerouter + Unifi switches and APs, and a Mikrotik router too. Of

by gh02t 6y ago
I personally wouldn't recommend it, the USG and their other Unifi gateways are actually kinda limited feature wise. You get all the stuff in the dashboard, but I'd say it's fairly primitive compared to what you'd be used
444.
by gh02t 6y ago
It's not, the parent is wrong. I'm not sure if I would 100% recommend one (it depends on your needs and how nervous Ubiquiti's recent business decisions make you), but it's not discontinued nor about to be.
445.
by gh02t 6y ago
This is wrong. First, the UDM is not discontinued- it's for sale right now. Second, you don't need a USG+key to do VLANs. You do need to run a Unifi controller, but you can self host that anywhere like on a RasPi or in a VM. You d

Having owned several products from both, Mikrotik equivalents are generally way more feature packed but I find them hard to use. EdgeMax stuff is more polished, but has fewer features. Performance is comparable for the most part.

I'm not sure if there really are any affordable FPGAs that are capable of running a RISC-V core with anything even approaching desktop performance. You'd likely struggle to get even original gen 1 Raspberry Pi performance out of a

Programming a bitstream onto the FPGA is relatively quick, it's perfectly feasible. The time consuming part is in development and synthesis.

I quite like the taste, it has a mild but distinctive flavor but it's much better in the background and it can be overpowering if it's the main flavor, which was my complaint with KFC. Kinda similar to salt, a bit of salt makes
