I've learned a ton about the homeless population and shelter process. I've been a volunteer leading health assessments and triage (via volunteer Telehealth nurses) at our local men's shelter. The shelter has even experienced a complete move in the last week. A few huge points, however: * Homelessness isn't always a choice - and especially in this situation it's causing panic. * Our shelter system needs much greater s…

To help with this, studies indicate that you can heat items in the oven at 70C for 30 minutes for effective sterilization without compromising the masks. More detail at [1]. My household is also using this technique on things like incoming mail, etc.

Bravo on your work - stay safe!

I've been dividing my life into different parts - fitness, technology, wisdom, food and love. Fitness, I cannot hit the gym anymore so at home I'm doing body weight training goals. Current goal is 1k squats a day(done), 1k burpees day(70/day right now, It's 1 week in so progress is very fast right now), and a bodyweight program my gym is offering. For tech, I'm learning machine learning applied to a environmental pro…

First of all congrats of mental fortitude to do 1k squats/burpees. That's quite insane. May I offer an opinion here - doing 1k body-weight squats is like doing 'hello world' 1000 times and trying to progress in programming :) Bigger ROI if you fill up a backpack with books and do 100 of them from strength, time (and probably endurance) perspective.

Would it be okay sharing how you are approaching options trading? What steps would you recommend someone who would like to start with the basics?

I'm also interested in this. Would be great to share some resources.

Golden rule from my perspective, regardless of asset - don't follow analysts (it's all about risk management and if strategy/indicator is public it's highly likely ineffective) and price action is king. Playing with automation as supplement to above is smart investment.

Doing this part-time studying + working thing right now, finishing up my first year of Informatics/CS after changing my major. For school, I'm learning networking. Finding it a bit dry, especially learning about packet structures and such. The book we're using, "Computer Networking: A Top-Down Approach" by Kurose & Ross[1] is great and the authors' personalities really shine through! For work I'm learning about datab…

Right now I'm learning Gatsby and re-learning React after having done one project with it and putting it down for 12+ months.

I'm learning how to rebuild my 3d printer for the third(?) time. Each time something breaks it starts off as blind confusion, and over the weeks I figure it out and then I feel like a genius when it it works.

I have a business I want to build, and I'm working on estimating what the cost of the individual items / products are, how long they take, and how long it really "costs" me. I'm working on fixing up the website and improving it.

I have a wall of post-it notes in different colors I'm using to track all of this stuff. As a developer I hate time tracking and project management in general but I'm learning a lot by doing it myself. Progress is slow, but at least there is progress.

I grew up in Nashua, and when I looked at your posts about restoring your home it made me nostalgic for New Hampshire.

Ah I grew up in Nashua too, at 37 Orange street, if you've ever seen the house (An 1840's house, just at the start of the downtown historic district)

Here's how I tell people how my experience of Nashua has changed: "When I was young, we used to tell people how to get to our house by saying at one point, 'Turn right where the cows are. You'll go over an old stone bridge and then through some narrow curves on a few hills. Then turn right at..."

Then it turned into "Turn right where the cows used to be."

Then it became "Turn right at the ____ subdivision."

When I was young I did a lot of bicycling and running. In early high school (1980s) a friend and I used to ride our bikes as far as we could in the morning, and then try to find our way back without asking for directions. We found all kinds of old back roads and small cemeteries and old stone walls and other remnants of old New England. Now when I go back and go for a run or a drive it's endless subdivisions. I don't resent that at all, I know things grow and change. But it's certainly part of why I don't miss Nashua much except for nostalgia.

Cybersecurity! I just started on Hack The Box. I am not sure if I want to go all the way for OSCP. Regardless, it is really fun and I've always wanted to learn how to "hack".

I've been learning Korean, I recently found out that it is a language that was invented rather than evolving over time. It was created with the intention to be easy to learn. The entire alphabet is 24 characters, whereas Japanese has over 500 and Mandarin has a few thousand. Each of the 24 characters follow very logical rules and build onto each other to build "blocks" of syllables. Each block must start with a conso…

The alphabet was created not the language itself. Hangul is indeed designed for the Korean language, a natural language.

You are correct, my mistake. Thank you for the clarification.

Out of curiosity How’s life in Alaska. It has always been a dream for me to move to Alaska since its a beautiful state and last thing what about the jobs there

I love Alaska. I live in Sitka, which is a small town on the side of an island. We have about 10k people, but our town is a 14-mile by 1/2 mile strip of land on a 100-mile long island that's almost entirely wilderness. I like that we're a big enough town to have a thriving community - good educational opportunities, a variety of work available, an impressive arts community. But you can walk into the woods anywhere at the edge of town and immediately find yourself in actual wilderness. Subsistence is also a way of life for most people - almost everyone has a freezer with fish and wild game that they caught themselves.

The virus is going to have a serious impact here, like so many places. So many people depend on the summer tourism season to make a living. There are charter fishing operations, tour operations, retail operations. Those people and businesses will make almost nothing this year. And when this is over, how long will it take people to be able to afford summer travel again?

Currently hacking up a prototype of a puppet-like system for automating host setup.

So far I can parse a configuration file, apply rules, handle (manually specified) dependencies, and configure triggers to run on rule-actions.

Not a bad state to be in for a few hours work. Of course the big decision is if I continue, and write modules for doing more than I have right now. I suspect the rational answer should be "no". But I kinda like the existing implementation, and being go it is trivial to install/deploy.
