A talk by Nickolas Means, as recorded at Fronteers 2018(which I attended).
On July 19, 1989, United Airlines Flight 232 was en route to Chicago when a mechanical failure caused the plane to become all but uncontrollable. In this unsurvivable situation, the flight crew saved more than half of those onboard. How did they do it?
Flight crews and software teams have a lot in common, and there’s much we can learn from how the best crews do their jobs. What can we learn from the story of United 232? While this talk won’t earn you your pilot’s license, you’ll definitely come away with some fresh ideas on how to make your team even more amazing.
If the audio is bothering you (there seems to be a bit of an audio loop in there?), there’s this rendition from 2016 that you might enjoy instead:
Recoil is the State Management Library for React they use at Facebook.
Recoil lets you create a data-flow graph that flows from atoms (shared state) through selectors (pure functions) and down into your React components. Atoms are units of state that components can subscribe to. Selectors transform this state either synchronously or asynchronously
Best to watch the talk from React Europe 2020 embedded above. It clearly explains why Recoil come to exist, and when & how to use it.
This simulator will familiarize you with the controls of the actual interface used by NASA Astronauts to manually pilot the SpaceX Dragon 2 vehicle to the International Space Station. Successful docking is achieved when all green numbers in the center of the interface are below 0.2. Movement in space is slow and requires patience & precision.
Ever since September 2019 I had this issue with my MacBook Pro where kernel_task would sometimes spike up to > 1000% (!) CPU load and drain my battery – even while connected to a charger.
Second time this month kernel_task (with pid 0) decided to go nuts and drain my battery until my macbook shut down (even while connected to a power brick)
And yes, that totally explained my problem. As the linked StackExchange thread mentions:
High CPU usage by kernel_task is caused by high Thunderbolt Left Proximity temperature, which is caused by charging and having normal peripherals plugged in at the same time.
So the fix is simple: don’t charge your MacBook from the left side but use the right side.
Now this is not something I’d expect from a +$3000 costing machine but as the late Steve Jobs would say: “You’re holding charging it wrong” … ¯\_(ツ)_/¯
One of the functions of kernel_task is to help manage CPU temperature by making the CPU less available to processes that are using it intensely. In other words, kernel_task responds to conditions that cause your CPU to become too hot, even if your Mac doesn’t feel hot to you. It does not itself cause those conditions. When the CPU temperature decreases, kernel_task automatically reduces its activity.
So it’s basically kernel_task trying to steal CPU cycles from other processes, so that those processes don’t overheat the system.
Did this help you out? Like what you see? Thank me with a coffee.
I don't do this for profit but a small one-time donation would always put a smile on my face. Thanks!
In case you were wondering: it’s a regular Pong game, but with the elements visually hidden (opacity: 0;) so that they only show up in the DevTools’ Layers Panel.
The past few weeks I’ve been enjoying the newsletter of Remix, an yet to be released React Framework
Remix is a web application framework for React from the authors of React Router: Michael Jackson and Ryan Florence. It provides APIs and conventions for server rendering, data loading, routing and more.
You can also read some of its details in their introductory post from two weeks ago. I really like this post, as they build up their code examples in a step-by-step manner. In that post they cover their approach to:
File System Routing
Data Loading
Location-Based Cache
Meta Tags and Document Titles
Remix will be a paid product. Next to a Commercial License they’ll also provide an Affordable Indie License.
Every time you visit “This Word Does Not Exist” it will spit out a word that does not exist, along with its description and an example sentence containing the word.
This Word Does Not Exist uses an artificial intelligence model named GPT-2 to invent new English words.
The folks over at Callstack have published a series on React Native Optimization:
In this and the following articles, we will show you how to optimize the performance and stability of your apps. Thanks to the practices described in the guide, you will improve the user experience and speed up the time-to-market of your apps.
The whole guide is divided into 18 articles, which will be published regularly. Over time, all these articles will be collected in one place and made available as one large ebook for download.
