Search - "fast"
I'm convinced that playing the piano has allowed me to type faster and commit keyboard shortcuts to muscle memory faster too. While coding isn't about typing quickly, there's a whole bunch of times when I've had an idea, and had to get that down into code as quickly as possible before I forget it - and that's when I really find fast keyboard work comes into its own.3
My professor asked for some images of cool stuff I worked on for a presentation he is giving. So here is me moving fast enough to cause motion blur :) The code is using the camera to detect people, and then project the bounding box down in the lidar frame, and mask all the lidar points within that cone.
Anyway, if someone is familiar with super fast agglomerative clustering code in C++ (or even python, if it's efficient), please share it with me!7
Come on guys, use those JSON schemas properly. The number of times I see people going "err, few strings here, any other properties ok, no properties required, job done." Dahhh, that's pointless. Lock that bloody thing down as much as you possibly can.
I mean, the damn things can be used to fail fast whenever you misspell properties, miss required properties, format dates wrong - heck, even when you want to validate the set format of an array - and then libraries will throw back an error to your client (or logs if you're just on backend) and tell you *exactly what's wrong.* It's immensely powerful, and all you have to do is craft a decent schema to get it for free.
If I see one more person trying to validate their JSON manually in 500 lines of buggy code and throwing ambiguous error messages when it could have been trivially handled by a schema, I'm going to scream.18
"Fast" random-number/sample based estimation of logarithms:
The result of rAvg(p) is usually "pretty close" to log(p)/2
rAvg(p, 1000) seems to be the golden number. 100 is a little low, but I've already pasted the code. Eh.
Don't know why it works, or if average results are actually considered "close" for logarithms of e.7
To the reactjs-centered fucks who develop the popular web component viewing software called storybook: have you ever heard about semver?
89 alpha/beta/rc releases for a minor update 6.3 -> 6.4 with "100's of fixes and enhancements" "in preparation of the HUGE 7.0 release". Gee I wonder will it have 1000's of bugfixes? How bug-ridden is this software?
Every minor upgrade since 5.x is backwards-incompatible and requires a day of frustration finding out in how many more fucking NPM packages you split your codebase just because it's cool. I know move fast and break things, but some of us have other things to do than resolving node_modules incompatibilities you know. "No just hit 'npx sb upgrade' you say". I did, I really did! And the browser showed a blank screen of death with tons of cryptic React errors, it really did! Thank God you abstracted away all your dependencies in that sb command, now you can't even read the docs about what could have gone wrong with a specific sub-package. You have @storybook/html but the docs redirect to React pages, so good luck if you use something else
This is so sad... like.. the IDEA of storybook is great. But why did faith put the capacity to develop such a tool into the hands of people who think the world centers around React and JSX.. HTML should have been the default, and then you build on top of that for your fav framework, not the other way around
