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 io_uring because I'm not as up to date on th

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 wherever docker is hosting the serverside piece of Offload.

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 people." -- Shanemhansen

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 bandwidth than both AVC and HEVC, resulting in 45% fewer buffer

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 "reclaimable cache". Another way to approach it if yo

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 indicates that actually you can use performance mo

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 months studying Phillip Greenspuns books. It also

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 some service like nginx. The language itself is pretty f

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 calls. 1. Kernel bypass combined with DMA and techniques

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 the alternator. I still don't know why I perceive

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 seen

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 why they should be handled separately.

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 than "yeah we want to spend less on peopl

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 <manager, skip level, .... , CEO, business value>. 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 humane way. I don't want to put words in your mouth but

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 has been that overuse of channels is a code smell that

For me personally tests have a positive ROI within hours. Even if I was doing a one day hackathon I'd probably have some sort of test feedback loop. I've dealt with P1 bugs that cost the company 100k/minute and still took the

I think Tcl as it was back then especially would have been a terrible DOM manipulation choice. I love the language but the hacks frameworks like openacs used to use to imitate basic stuff like a list of database records are among the uglies

If I remember correctly early HTML specs actually used Tcl as an example for script tag content. It was definitely possible that Tcl could have ended up the web sripting language.

I wonder how well this will actually work. The core problem is that alot of crawlers aren't spending their money. They are part of a botnet so they are just spending the victim's money. But hopefully most of the crawlers aren&#x27
