Just an interesting observation I had about this once when I noticed that kernel quic implementations weren't very fast. KTLS is mostly useful if paired with sendfile (I'm ignoring…

They said bind mounts would still work. I didn't think those worked with remote engines. Which also seems to imply the client software will expose your laptops filesystem to wherev…

I've thought of this quote a bunch and I came up with my own addon. "Some people think that the magic of something wondrous is diminished when it's understood. I feel bad for those…

Going to write a real banger of a paper called "latency numbers considered harmful is all you need" and watch my academic cred go through the roof.

> AV1 streaming sessions achieve VMAF scores¹ that are 4.3 points higher than AVC and 0.9 points higher than HEVC sessions. At the same time, AV1 sessions use one-third less bandwi…

This actually seems like a simple example of memory request vs limit. Request the amount of memory needed to be healthy, you can potentially set the limit higher to account for "re…

I'd think something like Rump Kernel's is a closer analogue: https://en.wikipedia.org/wiki/Rump_kernel

You nerd sniped me a little and I'll admit I'm not 100% sure what a reduction is but I've understood it to be a measurement of work for scheduling purposes. A bit of googling indic…

The unreasonable effectiveness of profiling and digging deep strikes again.

Tcl was my first "general purpose" programming language (after TI-basic and Matlab). When I started that job I didn't know the difference between Tcl and TCP. I spent a couple mont…

The closeness of this syntax to graphviz dot is very interesting. having dgsh output a graphvis file in dry-run mode would be a neat feature.

Fundamentally it's a programming language so all the normal ways of running it apply: Use their library in your application to evaluate policies. Run it from the cli. Embed it in s…

You are right but it's confusing because there are two different approaches. I guess you could say both approaches improve performance by eliminating context switches and system ca…

I had this for a reverse proxy I developed that did some transformations. At about two critical points if there was an error there was literally nothing we could do except 500 barf…

I've wondered about PWM flicker when I started trying to figure out why so many modern car headlights seem like they are strobing to me. Initially I thought it might be related to …

You don't do a HTTPS handshake by hand. That's what openssl s_client is for. https://docs.openssl.org/1.0.2/man1/s_client/ Or maybe socat, I don't use it but I'm pretty sure I've s…

To me traces (or maybe more specifically spans) are essentially a structured log with a unique ID and a reference to a parent ID. Very open to have someone explain why I'm wrong or…

I don't believe them. I believe that as we exit zero interest rates, companies have to cut back and "we are doing AI" is easier to sell the investors and even their own employees t…

I agree. Sometimes doing good work feels like a curve fitting problem where the objective function is a function not only of "value" but value to . I learned this the hard way.

You're probably right. There are certain literal statements I react strongly to. I understand at work I have a job to do, but I choose how to do it and I choose to do it in a human…

> As a manager, your empathy needs to be highly conditional. Your job is to get to the truth of a matter in a respectful way, not make your team feel good. Doubt. Specifically abou…

Well it absolutely muddles your mind when you're on it and it causes constipation. It can also depress your respiratory system.

Science News is a big part of my childhood. My stepdad's dad was a subscriber and every issue was handed down to us gently used. I have thousands of back issues.

I'll offer a counterpoint to the responses. Until go got generics, concurrent data structures were awkward. The stdlib now does include things like sync.Map. In fact my experience …

"I don't endorse this paper. Therefore you should take it down. I won't tell you why. Trust me bro." Whether MIT is right or wrong, the arrogance displayed is staggering. The only …
