I'm making YouTube content to help people learn Google Cloud and also prepare for the GCP certifications: https://www.youtube.com/channel/UCIGDDqu5DzlaaC4XzXj_4-A There is an unlisted sample video in there that I've put out for feedback, and I'm making changes based on that. Will also be putting together related content around GCP. p.s. do subscribe to the channel.

Hey, I wasn't sure where to leave the feedback so I'll leave it here: it might be a good idea to get a microphone to improve the sound quality and clarity. It's a bit hard to hear. Keep it up!

Im aggregating stock chatter from the worst parts of the internet (wallstreetbets, 4chan), summarizing it and sending it out as a newsletter here: https://topstonks.com

Why is this a newsletter that you need to give your email address even to just sample the content? It would be much nicer if the website showed you the content with an option to subscribe to the newsletter or rss feed.

Solving the world's trillion-dollar energy storage crisis. (multi-trillion, actually.) https://www.terramenthq.com/

About a year ago, I started spending more time researching about climate change. I learned how important energy storage will be to enable renewable energy to displace fossil fuels. The more I read, the more fascinated I became with the idea of building underground pumped hydro energy storage. I found a research paper from the U.S. DOE written in 1984 showing that the idea was perfectly feasible and affordable, but it seems that nearly everyone has forgotten about it since. (they didn't build it at the time because the demand wasn't there yet. Now energy storage demand is growing exponentially)

A year later, I'm applying for grant funding to get it built. I know that nearly everyone will tell me I can't do it because this or that reason. Because people don't like change and they're scared of big things even if the research shows it makes perfect sense. But I'm doing it anyways because no one else is getting it done. The idea is too compelling and too important to ignore. So here goes nothing!

1. Trying to make hiring in tech a better experience by sharing my knowledge and experience with both job seekers and those doing the hiring. The really hard part about this is influencing some change in how hiring is done, because I strongly believe the current hiring process selects for the wrong skillset. I'm publicly committing to write about this topic weekly with a newsletter that I just launched: https://hirin…

Is it possible for you to add an Atom feed for #1? I try to reserve email for real communication and use feeds for reading periodicals. I would subscribe to it as a feed, but it doesn't belong in my email.

Absolutely! The feed will be available at https://hiringfor.tech/feed.xml when I start publish content (probably next week).

Somewhat of a departure from the rest of the current comments. I'm a dataminer/rom hacker mainly working on Nintendo handheld systems from the DS onward and I've recently resigned myself to learning the sort of ASM code needed to reverse engineer compiled assets (since obviously I have no way of getting a pre-compiled version of those assets). I've been looking into the legality of reverse engineering and I've always…

That sounds awesome! Are these things you're doing for work, or on your own (or both)? I'm not much of a gamer, and I don't know what the market looks like for Nintendo systems...what are the applications for custom ROMs on DSs and other handheld systems? Some excellent free reverse engineering courses for Windows[0] and Linux[1] were posted in another HN thread recently, and a couple other HNers and I started a stud…

> what are the applications for custom ROMs on DSs and other handheld systems?

Having played around a bit with a jailbroken Switch, the primary reason is to be able to either run mods for games (e.g. there's a surprisingly viable set of tools for converting/bundling Skyrim mods for PC for use on the Switch version) or to run homebrew apps, the common ones being emulators. Previously, I had played around with GBA emulators on PSP/PS Vita, but the Switch form factor and screen size are a lot nicer to play on.

That being said, you could also go the route of putting a completely foreign OS instead of just modified Switch firmware. Android seems to run flawlessly on a Switch from my testing; even though Android doesn't seem to be able to access the joy cons directly when they're attached, you can still pair them with bluetooth and they work fine even when they're slotted in. Android even seems to have pretty good built-in support for that kind of input device; you can easily navigate through the icons on the home screen, hit "A" to select whatever's highlighted, etc.

Problem: The hassle of splitting proceeds from a service/event/product sale after the fact related to sending/collecting your % share, timing and details of wiring the proceeds. Solution: Pre-set allocations and create a customized checkout so that splits happen on a per-payment basis. Members dont have to wait to get their share. https://www.korabo.io Idea kind of came about after watching my wife, who is a yoga ins…

Is this using Stripe Connect behind the scenes? They are trying to solve a similar problem. I tried to register on Korabo but after I signed up and went to login I got an error saying I needed to confirm my email. Haven’t gotten the email confirmation though, so something may be broken into your onboarding flow.

Thanks a lot for the response. Yes exactly, its using Stripe Connect and related APIs.

Basically just leveraging a lot of Stripes features which are great. Their support has been super helpful as well advising on what can and can not be done.

Noted on the onboarding issue. Will check whats going on there. When I signed up myself, gmail classified it as junk/spam, possibly rightfully so.

Thanks again.

Earlier quoted context omitted.

The biggest problem I'm facing right now is credit card processing costs. The restaurant business is a high revenue, low margin industry. The fees are higher for online transactions (no card present) vs. in person transactions (card present), on the order of 1-2%. I think this is the biggest reason it hasn't happened yet. However, I have a workaround which I think will work.

Oh no. Not another crypto currency or other virtual currency I hope.

Nope.
