We're definitely talking about different things. The open internet is hostile and you'll always need load shedding when the clients misbehave. If you control all clients and server…

If your clients are all this well behaved, then you’re definitely not exposed to the public internet. The global edge networks that I’m aware of all use L4 LBs and L7 LBs. Cloudfla…

IME sports doctors and physios have incentives aligned with returning to high functionality. I think this causes them to clinically converge on effective treatments. It’s also poss…

Having strong muscles around the joint won't fix a structural problem, but they definitely won't hurt. When I tore my ACL doing bjj, I was surprised to see that some pro MMA fighte…

Sounds half baked. What context does this function run in? Is it an interpreted language or an executable that you provide? Inotify is the way to shovel these events out of the ker…

git ls-files | entr pre-commit

No. You sit on the call and wait to restore your service to your users. There’s bullshit toil in disabling scale in as the outage gets longer. Eventually, AWS has a VP of something…

The worst SEV calls are the one where you twiddle your thumbs waiting for a support rep to drop a crumb of information about the provider outage. You wake up. It's not your fault. …

The Facebook "little red book" had a quote in it along these lines: When you don't realize what you can't do, you can do some pretty cool stuff

Do Cloudflare's floating egress IPs probe in a way where you can easily geolocate them? https://blog.cloudflare.com/cloudflare-servers-dont-own-ips-...

Google, Apple, and Meta (maybe others?) have the data to build a complete GeoIP dataset. None of them will share because there are only downsides to doing so. When FB was rolling o…

I see a single IP for all 3 While I'm here: Google uses edns0 client subnet to geo target your client IP. Try a dig -t txt o-o.myaddr.l.google.com @8.8.8.8 vs the others to see the…

It depends on how long they're above the speed limit and you're below it. If you want to win the race, max acceleration, max speed, max deceleration. Anything else is sub optimal.

Amusing that they don't mention xds at all. How did they "win" when xds, envoy's config, is becoming the defacto interface to LBs? Sure, Gateway API is kinda xds by not, but it's e…

Onavo was the vpn app turned competitive intelligence tool

10 years ago at Facebook we had a systems design interview question called "botnet crawl" where the set up that I'd give would be: I'm an entrepreneur who is going to get rich sell…

I worked on the laser printers in the early 2000s when they transitioned to Linux for the OS. They were hiring Linux nerds and I fit the bill. It was a fun place for a while, but t…

Google was available at google.stanford.edu before they spun up the company. I saw Sergei give a talk at my university in 96 or 97 and switched from Alta Vista.

Aktiia makes a continuous optical blood pressure monitor that is available in the EU. It's like wearing a fitbit, but for bp. You calibrate it with a pressure cuff once a month. I'…

You don't need full blown workspace, which costs money, you can set up "cloud identity free" and claim the domain. When you're setting it up, you can choose what to do with any exi…

Exactly what an NSA puppet account would say! Don't believe the hype. Remember the smiley from "SSL added and removed here" https://blog.encrypt.me/2013/11/05/ssl-added-and-removed…

I'm using rules_distroless+rules_oci with bazel to build small Ubuntu based images. It takes some effort, but ends up being pretty nice.

Non-Koreans who live and work in South Korea pay South Korean taxes

Uber works in S Korea now. It also accepts non-Korean credit cards, while most online apps in South Korea do not.

When did Kakao Bank start offering accounts to foreigners with ARCs? Last I checked it did not.
