In networking, TCP is probably the most familiar communication protocol. To guarantee transmission accuracy, a series of mechanisms are required to ensure data integrity and reliable reception between both sides. A similar process is necessary in hardware as well.
Build an air quality monitoring application using Arduino, ESP32, and sensors! While it's called "air quality," the implementation currently only monitors CO2 concentration, temperature, and humidity—though adding other sensors wouldn't be much of an issue if you have them.
Starting a data science journey from scratch.
Set on a frigid snowy mountain, eight players must cooperate to gather resources, repair power generators, call for a rescue helicopter, and make their escape. Along the way, players must contend not only with the elements (wild animals, freezing temperatures, and hunger) but also unexpected random events.
Around mid-February, the COVID-19 outbreak began spreading in Tokyo. Although I work in Fukuoka, my company announced a remote work policy in late February to curb the spread, reduce commute times, and lower infection risks. Here are some of my reflections.
Typora is a Markdown text editor I really love. However, there's always been one pain point: image uploads. By default, Typora only inserts the local file path into your Markdown...
I've wanted to experiment with smart home appliances for a long time, but my current appliances are already fixed in place and lack built-in network connectivity. Converting them directly into smart appliances would require extra renovation work, which isn't easy to do.
My feelings were somewhat mixed after my manager promoted me to Tech Lead. There was no corresponding bump in job level, nor an official new title—just a tap on the shoulder saying, "Hey, from now on you're the Tech Lead," along with a slight raise.
When researching a new library, I also research the person behind it (not all of them, of course, or a single npm install would take a lifetime to inspect). That's because the creators of technology, libraries, and frameworks are human beings—flesh and blood, with real feelings.
In Part 1, we covered how to write a JSON parser and implemented string parsing. Next, we'll fill in the rest of the functions. (In fact, once you understand the core principles, implementing the remaining functions is just following the recipe.)
Today, starting with JSON parsing, we will explain how to build a JSON parser from scratch. Since JSON has a simple structure, it makes for great practice.
Just as I was happily implementing smooth scroll in Svelte, I discovered that it can actually be done with a single line of CSS.
In the past, setting up CI often meant teams had to spend time debating (and arguing over) different solutions like CircleCI, Drone CI, Jenkins, and so on. However, if your team already hosts code on GitHub, you can effortlessly integrate CI directly with GitHub. While it may not be a silver bullet or a one-size-fits-all magic solution, I find it remarkably easy to achieve common goals like running tests or setting up push-and-deploy pipelines. Here is an introduction.
Today I browsed through Svelte's source code to get familiar with its architecture, and decided to see if there were any simple issues I could pick up for practice.
Screen recording is such a hassle, so I looked into whether you can record directly from the simulator—and turns out, you can!
It feels like Rollup's mechanisms aren't quite as comprehensive as Webpack's yet
However, the path Svelte has chosen is bound to run into certain issues—the most prominent being that Svelte can't do much for you at runtime.
When I first saw Svelte, I thought to myself, "Hmm... yet another front-end framework?", and didn't pay much attention. It wasn't until I started seeing more and more blog posts introducing it and many websites adopting it that my curiosity was piqued.
Reading about the blood, sweat, and tears of the flv.js developer left me deeply moved.
Starting from Chrome 80+, the default value of the `samesite` attribute for Cookies is set to `lax`. Starting from the definition of `samesite`, its purpose, and reflections on Cookies themselves, we will explore my thoughts on the whole matter.
