jason_slack··on Brain.fm: Music to improve focus, meditation and sleep
TBH, I value Brain.fm as a productive part of my work day.

Some days it helps focus on the endless housework and kid needs.

Other days it helps focus while coding.

As a polyphasic sleeper less than 2 mins of quiet relaxing music puts me to sleep.

jason_slack··on ReMarkable tablet open source tools and hacks
Thanks. I’m headed to medical school soon. Fingers crossed. My goal is zero distractions and a process for deep thought.
jason_slack··on ReMarkable tablet open source tools and hacks
> ReMarkable is sort of astonishingly expensive,

I have been contemplating buying a ReMarkable 2 as I prefer to handwrite everything/annotate/. The price tag is a bit hefty given the cost of an iPad and pencil and the zillion other things it does.

I'm curious if you are indeed going to buy one?

jason_slack··on eBird: A crowdsourced bird sighting database
I worked on the original eBird team back in the early 2000's. Seeing this post brought back so many memories of working very closely together on a small person team. At the time eBird was only a handful of people. The Lab of Ornithology continues to do amazing work. I'm happy they are thriving.
jason_slack··on An update to the Timescale license
I'm using TimescaleDB for algo trading and it is performing beautifully. It's been rock solid and is handling everything being thrown at it (and in my case, it's every second of every day, yes weekends too).

edit: I have about 24,000 tables most with millions of rows. All 24,000 tables are touched at least daily. Often every few seconds.

jason_slack··on Nano 5.0
I've often thought about contributing to the nano project. Having written a few editors myself I still have a passion for it. I use nano for quite a bit.
jason_slack··on Ask HN: Page Layout Tools in 2020
Thank you. I have been looking at Scribus
jason_slack··on Ask HN: Best resources to learn about stock trading and investing?
QuantInsti offers a course that is really in-depth. It’s like 4 months. All video based with live instructors, practice and tests. It’s worth the money IMHO.

Ernest Chan has written several books. He also offers live courses. He is one cool dude.

Learning to read candlestick charts and recognize patterns.

Backtesting your strategies is crucial.

Try to use data sources that haven’t introduced survivorship bias.

jason_slack··on Ask HN: What software does Linux need?
Thanks. I will be in bed :-)
jason_slack··on Polyphasic sleep takes napping to the extreme
I sleep about 2 hours (say 2:30am - 4:30am) and I want a 1 hour nap when my kids go down for a nap. It's not a standard pattern that you might read about, IIRC.
jason_slack··on Polyphasic sleep takes napping to the extreme
I am a long-term polyphasic sleeper. I've just always been this way. I have been told stories that as an infant I drove my family nuts with my lack of a need to sleep.

Now, I am 43 (in a few days), and polyphasic sleep has become a bit harder on me. Now, I am averaging between 2.5-3.5 hours each day but the real issue is if I get woken up. Example: a smoke detector goes off in the middle of the night. I can't go back to sleep because I will oversleep now. I am somewhat foggy for several hours after something like this.

Also, the opposite has been happening. I am on HRT and taking estrogen injections. On the day of my injection until about 2 days after I can not sleep. My body just won't allow it. Estrogen dominance has taken over. I am routinely up for 42-46 hours before my body gives in and demands sleep. I sleep 2-3 hours and I am awake. Not feeling replenished as I should and sometimes I feel like I need to be left alone for a long period of time so I don't inadvertently snap at my wife or children.

I'm happy to talk about whatever, AMA.

jason_slack··on Ask HN: Is there a whole universe of Chinese software that we don't see?
> - Cocos2D-X (2D game engine, this might be the only one > that's also really popular outside China): > https://www.cocos.com/en/

Yes, we are fairly lightweight and popular outside of China.

We offer Cocos2d-x, a c++/lua based game engine. There isn't a built in GUI editor, but FairyGUI works well.

Also, Cocos Creator, a JavaScript/TypeScript based game development environment. Creator is a complete development tool, GUI tool, etc.

jason_slack··on Ask HN: Do kids drag your career down?
I have a 1yr old and a 2yr old. I definitely struggle to find a balance some days because the kids are super needy and I always want to go heads down at my job. Perhaps if I worked out of the house I may be writing something different now.
jason_slack··on Ask HN: How to Contribute to the Markdown Standard?
Much appreciated. This looks perfect. Thank you for taking the time to reply to my submission.
jason_slack··on Don't write documentation in Markdown
As a technical writer, I write everything in Markdown.

Sure, it could use some features.

Does anyone know how a developer could contribute to the markdown standard and code up some desired markdown features?

jason_slack··on Ask HN: Book recommendations for understanding financial systems?
Dr Ernest Chan

Ray Dalio

Marcos Lopez de Prado

These authors are how I started. I'd be happy to list specific books if that is helpful, but I don't want to give you a false sense that if you read books I mention you will have the same understanding that I do.

jason_slack··on Ask HN: Was the Y2K crisis real?
My first real job out of college was for a company doing only Y2K prep. That is the reason why I was hired specifically.

I looked at every system and decided the fix and coded it up from Delphi, Access, SQL, VB, QBASIC and c++.

It was quite enjoyable and I was enjoying a glass of wine and a steak on the dreaded evening, which was a Friday. Not a single phone call until Monday morning when my boss said take a few days off but pay attention to my pager. I put it in the refridgerator :-)

jason_slack··on Chelsea Manning ordered to be released [pdf]
Ms. Manning. Thank you. Living a life under public scrutiny isn't for everyone. I appreciate your sacrafice and sticking to what you felt was right.
jason_slack··on Show HN: BeforeShutdown – a macOS menubar todo app with reminders on system off
Can you share where my to-do list data is stored? In your cloud or locally on my machine and you never see it. Thanks! The idea is interesting overall.
jason_slack··on All about Birds
You are correct, it goes to the lab directly.

jason_slack··on Ask HN: How to implement “office hours” as a software engineer?
I have a reputation for telling co-workers to leave me alone. I've had co-workers wave their hand in my face or come and tap me on the shoulder when I'm wearing headphones or send me e-mails marked as urgent and a variety of other ways to get my attention.

I'm nice, especially if I am new to the company.

I ask that if something isn't urgent that they send me an e-mail and I'll review it later, often at home in the evening.

I also would be open to a chat during lunch time, but not over a meal. Come to my cube and let's chat while we eat. I'm eating, you can choose not to do so. Eating is the priority, this isn't a hands on show me the code and get my keyboard all grease and food.

If something is urgent and it's my job, by all means come stick your hand in my face.

If something is urgent and it's not my job and you think I can fix it, please come stick your hand in my face but please don't do this often if it turns out you just want any geek at the company.

During the day I don't answer e-mail except for first thing in the morning and during the evening. I don't have notifications on.

Please don't stick a post-it note on my screen! I'm sure I have an inbox or a mailbox someplace you can deposit things in.

All of this being said, I try to be flexible with everyone, over and over, until I have to insist that I get my projects done. I like completing work that makes everyone say "Wow". This means my full attention to details and general awesomeness.

jason_slack··on Ask HN: Are books worth it?
This is true. It’s valid.

For me if I carry a book with me I’m going to read it. Carrying the weight of the physical books ensures I read it. I don’t want to carry it around for nothing.

jason_slack··on Ask HN: Are books worth it?
I own about 600 books currently. Ranging from A-Z in terms of subject matter. When I've moved, it has been a huge hassle to box and move and re-shelve them. My wife gets pretty irritated about this.

I wouldn't change this.

Physical book on specific subject matter tend to be very thorough compared to any content I could find online.

Physical books make me pay attention to it. They are right there in front. No blue light emissions, no notifications.

Physical books cost money. You can never sell them for anything near what you paid. I want every dollars worth our of them.

When someone asks me about a subject, if I own books on them I am happy to part with them and pass them along to that person provided they agree to do the same, if asked one day.

OP, please read more books, on any topic. Your mind, stress, creative spark will thank you.

jason_slack··on Music for Programming (2011)
I use Brain.fm daily. I love it.

I also switch to Soma.fm and Di.fm when needed.

jason_slack··on A $7 Credit Limit: Jack Ma’s Ant Lures Hundreds of Millions of Borrowers
I’ve taught all of my kids to maintain a checkbook, get receipts, understand paying bills and understand income versus expenses.

There is also this lost art or changing a tire, oil, checking fluids.

Civics wasn’t around when I was in high school but I remember my grandparents and parents had taken something similar.

jason_slack··on Tesla Cybertruck
I owned an Aztek and it was actually one of my more favorite cars because I could sleep in it if needed. I also really loved the Honda Element. I spend many a night at a beach and was very comfortable.
