I am learning Elixir and Phoenix. And to be honest I am not sure I like either. The lack of decent resources (I mainly use Python and JavaScript with some C#) so I am used to reading a lot of blog posts, I don’t really like the documentation and the answers in forums are over verbose. And then there is Ecto which gives me new respect for SQLAlchemy or even solutions in C#. Debugging is a bit rubbish as well and to to…

The book "Programming Elixir" is by far the best resource I found for learning the language.

I am going to read it, I have heard good things so will put it on the todo list for this week. I usually enjoy learning languages so I don’t know why I am hating on this so much ( last time I felt like this was with Ruby which was mainly due to the community )

You could also consider providing bioinformatics routines such as global and local sequence alignment. Under the hood they're very similar algorithms. https://en.wikipedia.org/wiki/Sequence_alignment https://en.wikipedia.org/wiki/Needleman%E2%80%93Wunsch_algor... https://en.wikipedia.org/wiki/Smith%E2%80%93Waterman_algorit...

Though I probably won't implement the different weighting schemes, I currently have alignment traceback and searching (allow "free shifts" for the pattern string) features.

Here's another recent SIMD aligner if you're interested:

I'm learning about trading bots. It allows me to learn new things about software développement (réactive streams forum example), mathematics, machine learning and deep learning I made it as a side project : https://github.com/cassandre-tech/cassandre-trading-bot And i am writing a guide about what i learned : https://trading-bot.cassandre.tech/

this is interesting! thanks for sharing

Oh man, this is a topic near and dear to my heart! I'm originally from California, but I lived in Mexico for several years. I am dying for some good traditional tacos. (Currently abroad but far from Mexico) The best tortillas I had were the handmade ones, made from organic blue maize.

I want to live in Mexico for a little bit one day. I imagine you came out of that with a taste for tacos that can't be matched anywhere. Were there any spots that you really enjoyed that had the organic blue maize that you liked or was it mostly abundant because Mexico hah? I'll definitely bookmark it :-)

I recommend it if possible. I had such an amazing experience living there. It's funny, I never miss the US but I always miss Mexico.

I mostly lived in Mexico City, but I've traveled a lot around the country and spent time living in a few other cities for shorter periods of time. I've probably seen more of Mexico than 90%+ of all Mexicans.

Some of the best food I've ever had was in a small Pueblo (town) called San Sebastián del Oeste in the state of Jalisco. [1] It's a small "magic town" in the mountains in Jalisco. [2]

Most of the best food I've had in Mexico was not in the big cities but in the small towns. Especially, the family-owned places where there's an older Mexican lady cooking up food. Cliché but true.

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…

Can you take a bit more about the environmental program and what you're doing with ML?

One trick for those that are not as advanced as you are: For whatever wheat you are using, add boiling water instead of cool water. I've found this trick worked (a few years ago now) for a couple of trials where I wanted to use just flour and water. I think the boiling water makes the flour more elastic.

Hot water encourages hydration of the flour and gluten development, resulting in a more elastic/homogeneous dough. IMHO, the hottest water from the tap should be good enough for that purpose.

True, but hot tap water doesn't always taste very good. If you've ever had seen the inside of a water heater, you will never want to consume hot water again. It's often full of rust and scale.

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.

I also have been learning about options. My goal has been to understand the financial sector better first and foremost, and only secondary is making some money. I am a newb whos only been going for about 6mos at this so fair warning to not listen to me at all.

1. The entire market is a big casino. The main question is what kind of risk you want to assume in your bet. Everything you do in the market is a bet/gamble. Don't fool yourself otherwise.

2. Options are a high risk avenue, but can also have some of the highest returns.

3. Learn the lingo. Traders use it so much you will be lost if you don't. (https://www.investorsunderground.com/acronyms/)

4. Start small to learn the ins and outs of your broker.

5. Understand that stocks are not a reflection of the companies actual value. They are a reflection of the markets perceived value of the company. The difference is enormous.

6. Do your own DD (due diligence). Read the docs the company has and is putting out. Do your own math. Don't rely on analysts, but you can use them as a reference.

7. Learn what IV crush is!!! (theta gang ftw)

8. Learn the most common strategies used. The wheel, put debit spread, cash covered calls, etc. Different situations and risk profiles in the moment are better suited to certain strategies.

9. See what crazy plays turned out good, and which ones bad, and seeing what strategy was used, how was the DD, etc.

10. Lastly, and less commonly talked about, never underestimate the power of powerful people's connections and interests in a company/stock. This is why I tend to focus heavily on ownership analysis and board analysis. Sometimes every normal, quant level algorithmic indicator points one way, but the connections say otherwise... and the connections almost always win out.
