The software that I am using to simulate the courses is GSPro. There are hundreds of courses on there. It's got just about every course you could imagine. Launch monitors come with their own software too and there are a few other options for simulating courses. E6 is one and GolfClub2019 is another. AwesomeGolf. GSPro is hard to beat though. For launch monitors, there are two main types: camera based and radar. Garmi…

To what extent does it make you a better real life golfer?

It’s helped me immensely. Just recently I feel like I’ve really broken thru to another level. I played real golf last week and had the best round of my life. Shot par+2 on the back on what’s considered one of the toughest courses in the area. Crushed the group I was with.I was teeing off first- I’m usually the guy not keeping score because it’s gonna be 110-130…

I had never practiced golf in my life(late 30’s) and would play 5-8 rounds every summer for last 10 ish years. So I had a ton of room for improvement. I also grew up playing competitive tennis, so the repetition of hitting a lot of balls is familiar and scratches an ich I’ve longed for.

I’ve just learned so much about golf from simulating golf that I never would have taken the time to learn.

And I’m sorta anti lessons and more learn on my own. So the sim is right up my alley. It’s also great exercise. 330 cals in less than an hour and I can play 18 in less than 40 mins…

I think everyone agrees it makes you a great ball striker. At the very least. Then the rest is golf. Which can be very very very tricky, even for the best of players.

I created a startup 2 years ago around a gigantic rabbit hole: understanding cause-and-effect and how you can move towards the outcome you want in a consistent way.

In case you want to have unlimited fun yourself, ask yourself: "What is the purpose of X?" and then "how can you measure/assess the fit-for-purpose of it?"

Possible Side-effects: #1 you might get disgusted and even angry with the self-declared "experts" who have not even understood the basic concepts.

#2 you might learn how little you understand yourself and how deep the rabbit hole goles.

Example in Software Development: Understand the quality dimensions for a "definition of ready" and what impact a good/used DoR has compared to a bad/not used DoR for the efficiency and effectiveness of a software development process.

> But let me stick with some basics. So, I can write and compile an x86 test.c program. Then, I use your extension and undo the linking. Then, I use the results to link again into a new executable? There are links in the README of my Ghidra extension repository that explain these use-cases in-depth on my blog, but as a summary: - You can delink the program as a whole and relink it. This can port a program from one fi…

This sounds like it would benefit from modifications to linkers to make decomposition easier. The benefits of code reuse might make it worthwhile, although the security implications of code reuse without having any idea of what's in the code seem formidable.

Some linkers can be instructed to leave the relocation sections in the output (-q/--emit-relocs for gold/mold), but it's extremely unlikely that an artifact you would care about was built with this obscure option.

I'm mostly using this delinking technique on PlayStation video games, Linux programs from the 90s and my own test programs, so I'm not that worried about security implications in my case. If you're stuffing bits and pieces taken from artifacts with questionable origins into programs and then execute them without due diligence, that's another story.

I have spent the. last few years (especially during COVID) to collect and explore the world of stationery. I now collect over 2500 items ranging from pens, pencils, stickers, a 50 yr old typewriter (functioning), note pads, old diaries, planners, gifting items, collectibles like from army, navy sets of pen, card holder and so much more, from around the world. It fascinates me to know such an amazing rabbit hole exists.

I totally agree, we are lucky here in Sweden to have free access to ice rinks, basic lessons are also rather cheap and usually operated but local not for profit organizations.

Where I live it is hot and humid for much of the year, so even though we get cold winters, it isn't enough to have outdoor ice rinks everywhere like in the Northern US, Canada, Eastern Europe, and Scandinavia. I'm jealous of the skating culture where you're at! One of my Canadian friends was explaining that pretty much everyone chooses to do either hockey or figure skating from a young age with a small minority doing…

I live in a suburb of Stockholm and it is like that, every neighborhood having its own ice rink, some are inhouse and some are opened, mostly free for use and divided for hours with and without hockey clubs.

I’ve fallen into the plant tissue culturing rabbit hole. I was selling excess trimmings of aquarium plants locally on Facebook marketplace and made a surprising amount of money, and my kids really enjoyed it (they got a cut for helping me out). I thought hmm, this could be a great excuse to make a little business around this, teach them some skills, get them thinking more constructively and feeling a sense of agency…

Do you think this would work with wasabi? Notoriously difficult to grow.

How hard to make something better than my hs8’s? I want an upgrade but next tier is like 3k

How much are you willing to spend? Troels Gravesen has many builds on his website and I'm sure some/many of them would be better than the HS8s. You could also search for "hs8" on diyaudio.com and see posts of people in a similar position.

I mean, hopefully less than 2k for something that’d be worth 3k for a pair of barefoot03’s ?

So, I decided to install Linux on my formerly-Windows-only laptop, and thought it was cool enough to go full time and ditch Windows completely. The downside was the lack of access to top tier games. No problem though, my plan was to take a break from gaming, figuring that by the time Linux had caught up with compatibility, computers would also be much more powerful and I'd be able to resume gaming at some point in th…

You just described my life back when Slackware OG was alpha in 1993, but on a 386 PC. 31 years later I never used my EE degree but traveled through all sorts of aspects of IT and IS.

I started with “Plants from Test Tubes: An Introduction to Micro-Propagation”. After reading that I’ve perused various sites, YouTube, and I find research papers are remarkably plentiful and useful when you’ve got a specific question. For example, I want to culture some plant. How do I get the best tissue from the plant and which media and hormones seem to work best? Should I use agar, gellan, multiply in a temporary…

Any online communities?

I’m not a part of any, but that’s a great idea. There are probably several out there.

Well... I wanted a dedicated AI/ML box here at home, with enough horsepower to do some interesting AI stuff (but without breaking the bank totally). So I built myself a new PC from parts for the first time in around 20 years. That was ... interesting. Building a PC is - in many ways - not that different than it was in 2005. But it's also changed in many ways. So I spent a lot of time researching and picking out parts, and then building the system. Which led me to things like spending hours watching youtube videos on "What's the best thermal paste" and "what's the best CPU cooler" and "are thermal pads better or worse than thermal paste" and "Do you need one of these CPU gasket things if you're running socket AM5" and so on.

I just got the box finished up over the weekend and it's working really nicely so far. I went with an MSI MEG x670e "Godlike" motherboard, AMD Ryzen 9 7950X CPU, MSI Gaming Radeon RX 7900 XTX GPU, and 64GB of DDR5 RAM. The whole thing is running Ubuntu 22.04 (I was going to use Alma Linux, but the Alma installer wouldn't even start), ROCm 6.1.0 and Ollama. So far I've mostly been working with the LLM stuff using Ollama and the llama3 model.

Now I've started using Spring AI to interface with the Ollama API. Next steps: figure out "function calling" with Ollama (which doesn't seem to be supported by Spring AI yet, boo) and some "agentic workflows" and multi-agent stuff...
