Re: Ask HN: What are you working on (September 2024)?
#752I recently switched jobs, and as I've become more comfortable in my new job, I realized that my old job completely sucked the creativity and fun out of programming for me. I did not have any energy for any projects in my spare time while working in my previous job, so the 1,5 months I've been focusing on taking small ideas and running with them.
This weekend I got an idea to create a 2D-pattern from a 1D initial pattern. I put it on https://ige.land/, and I find it very fun and satisfying to play around with. It's not so elegant and pretty, but it's fun for me, and that's all I was looking for! Click any cell to change that color in the pattern. Right click or long press to set the length of the 1D pattern. It's also fun to first create a pattern and then resize the browser window to see how it looks like.
So, what I'm working on is not really an interesting project or product. I'm working on my creativity, playing with code, and in general having more fun with programming. Making it magical for myself again.
I'm not sure if it's 100% in line with the spirit of the thread, but it's what I'm most excited to be working on! :-)

How would I even go about starting investing using this? Let's say I have a trading212 account or similar? Where do you even start? Do you have a "how to get started page" assuming someone knows little about investing.
https://grizzlybulls.com/how-it-works is the best page I have explaining the basics, but I probably need to be more accommodating to complete beginners. Grizzly Bulls is intended to be a great complement to the buy and hold passive indexing strategy that most people use.
The easiest way to use Grizzly Bulls is to hold VOO in any brokerage account, sell it when the model generates a sell signal, and then rebuy it when the model generates the next buy signal. A slightly more advanced but more tax efficient approach would be to open a margin account with futures trading permissions and sell S&P 500 Futures (ES or MES) of equal value to your VOO during sell signals, then repurchase the contracts you sold during the next buy signal. With this method, I've found you can usually reduce your overall tax burden to less than 15% and you'll only owe taxes on the net result of your futures trading.

#754I'm working on https://reciperium.com I've added a tutorial on https://learn.reciperium.com and a playground https://play.reciperium.com and I have around 4 active users (including myself, the most active and the target for this platform haha). In a nutshell, reciperium is the center of all my recipes, I was tired of finding recipes on different channels (youtube, reddit, instagram, google, friends, etc), and not hav…
I would actually use this, but I am unsure of it's pricing model and ease of backup. Perhaps I missed it somewhere. Good mobile support on my device. Two suggestions: - automatically convert units?, eg IP from Europe assume grams on some setting, convert {Rice}(2 cups) to grams when rendered - On the timer feature, create a timer (non popup) on the rendered section so I can just one press it to track time for me with…
Thanks for the feedback! Those features are in my roadmap, but I go at a slow rate next to my work. You'll probably see the timer before the unit conversion, as it's actually a hard problem. Did you know there's a US cup and a british cup (actually a few more)?? The problem may involve tracking the origin of the recipe if no lang is provided, or setting some defaults.
On the backup side, the easiest thing I'm introducing soon, is a "raw" button, where you can see the recipe raw, and you can download the `.recp` file. In the future, I'd like to have:
- Export all recipes and favorites
- And in case I give up with the platform: an obsidian integration, or a some kind of desktop app.
So just to be clear, I do want to have an escape hatch, even if the website doesn't succeed, I will still use the language. But, it's not my main priority at the moment.
Regarding the pricing model, I just don't see myself charging for a subscription. I've been thinking how to create a sustainable product. So far, what I have is a potential affiliate program. I want to use the recipe's materials to link to products. I think this is relative nonintrusive, and it's actually useful, because I've found myself reading a recipe and not knowing what something was, like a proofing basket, for example.
Let me know your thoughts.

wont your strategies incur short-term cap gains ? so, they will have to outperform the S&P 500 index to account for it. great start, and good luck.
Yes, but that's why the preferred method of implementation is using the S&P 500 futures (ES and MES) as the hedging tool during sell signals. With this method, you hold your preferred ETFs/stocks of choice forever and continue to accumulate unrealized gains indefinitely. Then on sell signals, you sell ES and MES of equivalent value to your long holdings to effectively go market neutral.
At the end of each year, you'll only owe taxes on the net result of your hedging with futures, and futures are section 1256 contracts so they are taxed as 60% long term gains / 40% short term gains regardless of holding period. In practice, I've found that this usually works out to an effective capital gains tax of less than 15% of annual profits. If a strategy returns a gross 30%, then the after-tax return would be about 25.5%.
Also, if you implement in a retirement account which many of our members do, capital gains are irrelevant.

Where are you sourcing your data from/what are you trading through?
I use Interactive Brokers for automated trade execution and as data source for real-time ES and VIX data. Data for the other indicators comes from a wide variety of sources. One of my favorites is https://fred.stlouisfed.org/.

Do they work in non-bull regimes?
Yes, in fact non-bull regimes are where they earn most of their relative outperformance. During buy signals, it's impossible for the models to outperform as they are long the S&P 500. During sell signals, they are in cash with the hopes of rebuying lower (doesn't always work out as they are of course imperfect). When the market is rising with low volatility, there aren't as many opportunities for outperformance.

#759I learned how to weld (MIG) and built a giant mushroom to house a mannequin I dubbed "the mushroom man" over about 100 hours in the last 4 weeks. I covered the outside with thick foam panels cut to size, cementing them in place with copious amounts of spray foam. I shaved the outside to a nice shape with a sawzall and the inside I covered in chicken-fenced, then attached a painters tarp to that (so it could be painte…
Where/how did you learn welding? Have been considering doing a community college welding course (as they have all the equipment, instruction, etc.).
I was using my dad's shop and MIG welder, so he was able to give me an intro. A buddy of mine is a millwright and came over and kindly taught me some tricks which brought me welds up to an acceptable quality.
After learning, I'd have to agree with one of the other responses, learning by Youtube is probably feasible. It's safer than I expected (less concern about touching metal in the ground path) though I'd strongly recommend investing in quality gloves, a quality helmet, and good thick pants, and a long-sleeved shirt / overcoat.
I thought about taking a course but I found this way of learning a lot more fun and engaging (if you're fortunate, as I am, to have experienced people in your life).
