I made a list a few weeks ago:

1. Finish my ml research project 2. Learn rust 3. Start a blog 4. Learn Lin alg and stats 5. Go through all of the deep learning book (goodfellow et al.) 6. Start working with GANs or RL

Other than that, I'm working on building my own Numpy-like array lib in Rust. I'd be glad to chat about it if anyone's interested

I'll probably get a lot of shit for this, but LeetCode. I've recently been furloughed, and I think that redundancies aren't too far away. There aren't many companies hiring in my area at the moment, and if I'm going to move it's going to be for a big company, so I'm dusting off the CV and am applying to some Big N companies. A recruiter recently reached out to me, and I've got an interview with one Big N company comi…

I don't hate you I pity you. Applied for Big N jobs last year, had to study leetcode for 1 month and I hated my life. I was legit depressed. I was already so busy at work and coming home to do leetcode just killed all motivation and happiness in my life. Did well enough to get to on site interviews but didn't get a full time offer from any of them. Such is life :(

I used to hate leetcode with passion because i associated it with being a failure in career.

I started leetcoding just for enjoyment and not for landing a FAANG job, when i had no interviews coming up. I started enjoying it a little bit and now i do it for "fun" and don't have an anatagonist realationship to it.

Like someone said, once you overcome something you have keep overcoming it, so you can never be successful if your strategy is overcoming.

Trying to learn Flutter!

I started learning Android but a lot of people shared their experience and it just doesn't seem worth it going all in on Android, especially considering that for most of my projects "native" experience is not a must (i.e. social app for sharing book opinions (i.e. a Goodreads which doesn't suck).

I am also impressed by the data, Flutter and Dart a growing incredibly, and I would like to be riding the early waves.

If anyone has any ideas, tips or experiences, please do share!

I am learning music production through a course on monthly.com, by Andrew Huang. I'm learning a lot of cool tricks and have made a lot of progress in my music production skills so far.

It is challenging though as I am creating my music on a Synthstrom Deluge instead of a typical DAW. Most of the concepts so far (1 week in) are still applicable although it requires a bit of creativity to apply certain concepts.

I just built my first mechanical keyboard which I wanted to do for years but never jumped shipped - The soldering scared me. It was easier and more fun than expected!

I also just bought a house and am looking into putting drywall in the garage.

I've been clearing land all day and bought 50lbs of buckwheat. I intend to try sowing/harvesting by hand. I will use this mostly for breads and pastries. This is something of an experiment. Building skills, I'm almost finished a chicken coop. I made a dry stone arch bridge but it failed because the frame sank, I will try again. I am learning carving to make wooden animal toys for my child, who will be born in July (I…

If you have any pictures available (especially of this bridge) I'd be curious to see. Are you tilling? Doing raised beds? We're planting a bit this year and dealing with weeds, etc. has been a hassle (also, most of the no-dig crowd seem to basically advocate using many tons of compost, which is great but not something you can assume a steady supply of)

There are lots of photos in this thread for the stone: https://twitter.com/simonsarris/status/1234186085200207872?s...

We're making semi raised beds up the hill: https://twitter.com/simonsarris/status/1246544902193909769?s...

With house compost and composted manure from a local farmer. The lower garden is mostly no till with added compost. We're not really sure what we're doing! So I can't really give advice.

I usually document what I'm working on on Twitter as a micro blog

I’m taking a Japanese class right now. Thinking about wanting to get to the level where I can play video games in Japanese to learn more. I don’t really play video games anymore because I largely find them a waste of time, but it’s an intriguing way to get back into them. I found a YouTube channel called “game grammar” which is really neat.

I'm porting Rodrigo Pombo's wonderful Build your own React[1] code to Clojure(script). It really helps understand what's going on under the hood. The goal is to replace a half-assed React-like implementation I currently have with something that works much better. [1] https://pomb.us/build-your-own-react/

I’ve been looking for a good real world project that uses Clojure to learn. I’ve only written basic backend services with it but love it.

I got hooked on Overtone and then switched over to hacking on a roguelike in Clojure. It's a fantastic language. :)

Learning Z80 assembler, matrix algebra, reloading (9mm, .45, etc.), how to draft detailed building plans (something that is detailed enough to get a building permit approved), and market "Technical Analysis" - the study of chart patterns to set buy/sell points.

  This all seems a bit silly, but everything is closed.  Also doing a lot of wood cutting and cleanup in the forest.  We built a custom designed Z80 SBC ( single board computer), with its own Z80MON monitor, and the genius guy I am working with has managed to put the BASIC interpreter into the monitor.  Just got MInipro installed and working on the MACbook, using HomeBrew.  I'm trying to get one of those TL866II pROM programmers - first one ordered got bounced by customs.  We've ordered second one, paid premium to have it couriered.  All the flights are ground-stopped, so it may be a while.   I really like the idea of building a whole computer from parts ordered from Mouser, having all the Monitor and interpreter code, and being able to download the code into A ROM chip, plug it in, and link to the thing with Kermit or Screen session from a Linux box, and have it process matrix data from our AI stuff.  
 
We live in deep farm country, where self-reliance is pretty hard core. Some farms up the road from ours, are not even on the grid. (They have wind generators and diesel tractors - some even have CNC machines).

We still have good internet access, and we are on-grid, but this whole virus-driven economic meltdown has absolutely confirmed our expectations. We are seriously looking at something that will look like the 1930's now. I worked in 8080 Assembler years ago, and I'd forgotten so much. But I've got two Z80 SBC's working now, one with it's own standalone VT-100 emulator board, and a little 40$ Chinese made VGA screen, which actually works pretty good. I can run that config off two lithium-ion batteries. The missing piece is to be able to use an SD-card. We have a prototype of a much more complex SBC that has a sound chip, and an SD card driver chip. It runs full CP/M, but I like the more simple design, since it does ot use surface mount - real old school.

And there is this ton of other stuff that must be done. We need to be able to reload, and I have all the dies and such for this. We are also doing a bunch of in-house food preparation, since the electricity is still working, and so we are making different types of food that can be easily frozen.

And the price action on the investment portfolios is requiring attention, since we have these predictive algorithms that are offering some insite into where to place trades. The markets are insane, but there are opportunites that do crop up. I realize that most traditional "fundamental" analysis is of little value in this kind of environment, as the automatic algos are running most of the action. We have no chance at all of accessing any "government money", so we are really working our existing systems just to try to bring in some liquidity by quick in and out action. So far this is working, but it is absolutely crazy.

We have non-trading long-term positions on the left side of a tradional barbell, and these are just getting slaughtered. It feels like stories I read about in wartime, those First World War stories. Your whole "picture of the world" falls apart, and suddenly, all that crazy, hacky stuff you thought you would never really need or use (like the gas-mask in the garage) - suddenly, it's the stuff that is keeping you alive, and your economic and technical process actually working.

So, I am going thru notes, and invoking stuff that we documented back in 1987 ( mkt crash), and in 1998 (Russian Default), and of course the 9/11 stuff, which was short and sharp, and followed by a big pop. But the data this time suggests no - too much has been badly damaged already. So we are mainly working on a plan to survive economically, for the next 12 months.

We should be OK, but only because we had these backup Plan B and Plan C's and such. We went to Costco two days ago, and a hundred people were lined up, out into the parking lot, as "social distancing" was being enforced. It's making us pull out the SHTF playbook plans. It could all be summed up as "We are reviewing our strategies for maximum independece, and actively working to enhance our capacity for fully independent action." And I am reviewing all my Linux notes - we have several flavours of Linux boxes, that run the analytic and data management stuff. Need to ensure we can keep on keeping on. So far, it's all ticking along ok, but it's all up to us now. We are learning to be 100% self-supporting, I guess would sum it up. So far, it's working. But it's a new world now. We are all going to need a lot of different skills.
