Let start our issue. We cover HLS streaming, reverse engineering IoT. You also learn how to improve your site performance by moving critical css inline.
At WWDC2019, Apple has taken the wraps of its implementation of Low-Latency HLS streaming. This article discuss what Apple done to reduce publishing latency, eliminate segment round trip, reduce playlist transfer overhead and switch tiers quickly.
This article uses an example of an IoT monitoring/sensor device. The device had been deployed in shared rooms (e.g. meeting rooms) as well placed under the desk of individual employees. This article describes the investigation and analysis of that device, the possible problems along with proposed improvement
Implement a web server with different techniques: to teach Linux performance.
This paper presents the design, implementation, and deployment of Zanzibar, a global system for storing and evaluating access control lists. It has maintained 95th-percentile latency of less than 10 milliseconds and availability of greater than 99.999% over 3 years of production use.
We will use QEMU to run a kernel and look at stacktrace to figure out what happen. Good read if you love some low level stuff.
The browser must download and parse CSS files before it can show the page, which makes CSS a render-blocking resource. Critical CSS is a technique that extracts the CSS for above-the-fold content in order to render content to the user as fast as possible.
A Free course where they take us step by step for all deep learning stuff. A skill where many backend/frontend dev consider blackbox to them. You will need a computer with GPU, they have steps to help you launch these server in Google or Azure use free-tier.
the idea of BRIN is to avoid looking through definitely unsuited rows rather than quickly find the matching ones. This is always an inaccurate index: it does not contain TIDs of table rows at all.
A foxtrot merge is a specific sequence of git commits. A particularly nefarious sequence. Their graph looks like step of Foxtrot dance thus the name. They makes history mess up

I urge you to watch this 11mins video to know how to write function that help the compiler automatically optimize call stack.
SQL code is a bizarre combination of yelling and relational algebra. How can we make writing SQL easier? By embedding our own programming language in our SQL queries of course!
