When I was an intern at ON Semi, I worked on a testbed that was designed to stress power mosfets with extremely time-accurate pulses of current. The prototype was using an Arduino microcontroller, and I noticed that when I passed small valu

That's harder than you might think. How would you test for all possible uses? Even if you looked at something fundamental like an N-port, you'd still have to define metrics for usefulness and many of the topologies in the paper wo

18 is cool. Folding is a really under-rated and under-utilized technique. Common-gate impedance matching is "standard", but 22 uses it to also generate differential current outputs which is cool - I imagine it sees more use in RF

Some of these are standard, a few are genuinely clever, but many are bad designs and I'd never let someone tape them out in production. 2. Connecting the body terminal to something other than the highest voltage is dangerous and we rar

The same thing would happen on silicon. It's just a question of transition time. I've seen power mosfet inverters on some board designs, but you're probably better off using a discrete logic inverter because it would be cheap

I know gitea can mirror a github repo, not sure about issues or PRs though. If you're using gitlab or gitea you should be able to allow people to login with github accounts. I used that to raise issues about borgmatic[1] and it was ver

I don't think it's a yellow flag. It's hard enough to get contributors for FOSS as it is. Adding the additional hurdle of creating a new account would be counterproductive. Everyone already has a Github account so it's m

I had an extraordinarily hard time getting a monorepo set up for a proof of concept for a pretty basic dashboard app. I was using react for the frontend, node for the backend (Typescript for both), and GraphQL for the API. I tried both npm

I would suggest starting with the pfsense documentation. It's great!

by kayson 4y ago
While the interface may not be as pretty, you can do the same thing if you're running pfsense using the pfblocker-ng package: https://docs.netgate.com/pfsense/en/latest/packages/pfblocke... You can

The article is a little disingenuous. DDG didn't do this in secret and no one "found out". They announced it... Discussed at length here: https://news.ycombinator.com/item?id=31490515

I wonder why framework seems so much more popular. This product is a much better fit for me. I even prefer the fixed ports to frameworks modules. It looks cleaner and has all of the ports I'd need.

You can also use Healthchecks[0] or Uptime-Kuma[1] both of which are open source and self-hostable! I've been using both for a while and they're great. Healtchecks has first class integration in borgmatic[3], and is in my opinion

At a size on the order of 1um, it's going to be a long, long while before this becomes a commercially viable competitor to bulk cmos. Doesn't matter much for a CPU if your transistor can switch 1000000X faster if you can only have

Agreed. It's absolutely awful. Even a slight scroll up makes it show up again which is horribly inconvenient when you're trying to go back and forth between the graphics and the text describing them.

I don't buy that argument. ICs are massive. Way bigger in terms of number of schematic pages than any PCB. I think the problem is that PCB designers are used to having very "flat" schematics whereas IC designers always have a

by kayson 4y ago
The core ideas here are cool, but switching from a symbolic, schematic based approach to code seems insane for what amounts to strictly analog/RF design. In integrated circuit design, "modules", parametric components, and bul

Why do I have to sign up to do anything? I'd love to re-learn some algorithms, but forcing me to sign up to access anything at all just makes me want to not sign up. chess.com lets you do a bunch of stuff without signing up.

The thing that turned me away from ynab is that their marketing seems to say that they're trying to change spending/saving behavior in some way. I don't need to plan or make a zbb, I just want to easily categorize and track m

Without a way to easily import data directly from my banks/credit cards, using GnuCash (or Firefly III, a great alternative that's also worth checking out) just takes way more time than its worth. (OFX was not as straightforward t

5G in a lot of ways is a Solution in Search of a Problem. I think that's certainly the case for consumer cellular. In my mind, we already had enough bandwidth for almost everything that people do on their mobile devices, including stre

Around the same time as this article, I remember participating in a double blind study that was trying to evaluate something similar for movies. They wanted to test how audible it was to "discerning" listeners, so they contacted l

This is incredibly far-fetched. At best, a rogue actor within a foundry, who happens to be working on the correct process node, who happens to be on the account of the customer victim, might be able to access the GDS file (the full-chip lay

It would be disastrous. While TSMC does have a few foundries outside of Taiwan, the company accounts for about a third of total global semiconductor production. Maybe more if you consider just the most advanced process nodes. It's not
