Does your mom really know what TLS means? I would guess that even "tech savvy" members of the general public don't.

Is there lock-in for Wiz customers, besides the quality of the product? I understand the crazy revenue growth, fastest to 100m ARR, but surely this needs to saturate. Maybe half the fortune 500 use Wiz,but can you imagine 100% or even 80%? Who are their competitors?

Like all intel/amd integrated graphics that use the systems ram as vram?

Yes, but he is complaining about the change in policy on his Opinion articles.

The :- is supposed to sort of look like a left facing arrow for an implication. I think this notation started with prolog, so that is my guess why they chose to make it like this.

This is called a bootstrap circuit. It is basically positive feedback that changes the input impedance. You can see this sort of jfet circuit not only in trans-impedance amps, but also in a lot of audio circuits.

The modeling of unit systems with types is fraught with all sorts of inconsistencies and design tradeoffs. There are quantities that have the same dimensions, but shouldn't be compared or allow arithmetic between them. Many issues with Temperature scales and how to interpret differences in these spaces.

I think a pretty well thought out approach to this is the mp-units library in c++ that uses the ISQ(International System of Quantities) [1].

There are some great blog posts on their site about modeling units systems and dimensions. Fingers crossed it may even be added to the standard library in C++29.

I first saw this with Anthropic. I clear my browser pretty regularly and this flow just adds so much friction. With a password manager plus totp I never really felt burdened by logging in every time I used a service. I hope this doesn't catch on.

Thank you. I was also able to check that 631 is blocked by searching for it in output of sudo ufw show raw.

I am slightly confused. If I am using a linux laptop with cups do I need to do anything besides update? Is there a sane way to print from the linux desktop. I unfortunately need to regularly print, and often from public wifi.

Firefox with extensions? The current vertical tabs extensions are not nearly as nice, but Mozilla is working on native vertical tabs. Syncing and Workspaces are already better with Firefox then with Arc.

Just has the advantage that it is really cross platform instead of having subtly different "makes" on the unixes and windows.

Same issue with bash. Having something that really cares about windows support is useful.

This is the default solution for anything even slightly complicated. At very high frequencies(Rf), then you may be forced to use passive filters. The range where it makes sense to use active op-amp filters has shrunk considerably.

You get ease of prototyping,modification, and excellent performance. In these systems there may be still analog filter components(anti-aliasing,reconstruction), but with digital components so cheap,good, and fast this "mostly digital" technique is almost always the best option.

I have heard search based compiler optimization called "superoptimization"[1]. It seems interesting, but as far as I know has not seen much industrial use.
