Recently, I have been trying to build something of value, maybe offer a service or a product and it seems am out of ideas. So, what are some products and services used in every day living in the US/developed countries that are not yet available in other countries(Nigeria)?

New top story on Hacker News: Seems like everyone is getting rich
Seems like everyone is getting rich

It seems like everyone is getting rich these days: index funds , crypto, stock trading, collectibles, Wall street bets, tech jobs, fang jobs, home prices, prestigious jobs, etc. How do you prevent becoming discouraged or distracted when there seems like so many opportunities calling and so many people doing better

New top story on Hacker News: Launch HN: Kalam Labs (YC S21) – Science games and live game streaming for kids
Launch HN: Kalam Labs (YC S21) – Science games and live game streaming for kids
9 by KLFaraaz | 1 comments on Hacker News.
Hi HN, we're Ahmad, Sashakt, and Harshit of Kalam Labs ( https://ift.tt/3j5hXgm ). Kalam Labs lets 6 to 14 year old kids learn their favourite science topics by watching live game streams and playing science games. It's like Twitch for science, except you also get to play :) Here's a sample video of our live stream: https://www.youtube.com/watch?v=QGMmUg0N0HE High curiosity in kids is directly linked to better academic performance and better outcomes when they grow up. However, school leads to a drop in curiosity as they discourage asking questions and encourage “focussing on the blackboard.” Parents don’t have a solution, as internet resources are unstructured and unreliable and encyclopedias are static and boring for the kids. We were batchmates at our undergraduate degrees and worked together at India's largest educational body, NCERT. There we interacted with hundreds of kids, and they were really curious about science. Their heads were filled with questions like: Why is the sky blue? What is inside a black hole? etc. But the conventional teaching mediums were just too boring for them. So we started searching what do they want? Turns out almost every kid was on Roblox and Minecraft. There were entire communities there hanging out, hosting live streams chatting with each other. Digging deeper, we saw that Roblox and Minecraft are being extensively used as educational media. Microsoft has launched Minecraft for Education and Roblox has launched Roblox Education, and this was prompting teachers to migrate from Zoom to these multiplayer games. So we got it: we will use live game streaming to help kids learn science. We launched our MVP and saw phenomenal results. Generating $1k USD revenue in just a couple of days, we saw a market potential of scaling it and hence decided to start a startup around it. At Kalam Labs we host daily live game streams on kids' favourite science topics like space, black holes, and dinosaurs. During the live stream, an instructor takes the kids around a virtual world where they learn new topics by playing game-based exercises. The cool parts are: unlike a typical live game-stream on Twitch/YT where only the video of instructor playing a game is shared, at Kalam Labs kids can play the game with the instructor. This helps the instructor to give short fun activities for kids to solve for explaining any topic. In addition, our Live Chat has a tag-feature, which is really loved by kids. Instead of typing the entire chat, kids can just tap on the different recommendations and convey their thoughts. This leads to very high-engagement with sometimes kids liking the tapping feature more than the game itself. We are seeing cool metrics pop out due to this: Our average watch time of a live stream is 40 minutes - 5x higher than Youtube. Further, just launched in Mid-June our product has amassed thousands of paying customers growing 50% week-over-week. Please share your thoughts and feedback!

Show HN: With a 9-5 job and 2 kids I have finally finished my first MVP
62 by mrhichem | 29 comments on Hacker News.
Hello HN crowd. I worked on this project on weekends and evenings. I'm excited I made it into a presentable MVP, and it is so satisfying. I would like to get some honest feedback from this great community. I made https://ift.tt/3sPW7AF, to scratch a personal itch. I myself trade options as a hobby, and I didn't find a screener that satisfies my need to be able to explore raw options data freely and without preset constraints. So I made this app that allows playing with options market data and extract interesting opportunities. The techs used: - Laravel + Jquery + Mysql - Tradier API for market data - DigitalOcean for hosting - OVH for domain name It costs me 5$/month to run the website. I'll be glade to continue if it proves to be a viable product in the long run and maybe I will take it to the next level and try monetize it. Note: the app is not suitable for phone screens yet, although this is a planned feature.

I'm planing on taking some serious time off to work on my side projects. I'm open to any country in the world, I want to just work on my games. So with that in mind I'll need good internet access. From what I can see, this is very doable in Eastern Europe. Eventually, I do plan on returning to the US, but I want to spend at least 6 months overseas.

New top story on Hacker News: Show HN: Cassyni – Relaunching Academic Seminars
Show HN: Cassyni – Relaunching Academic Seminars
4 by arhpreston | 0 comments on Hacker News.
Hi, this is Andrew (arhpreston) and Ben (benjyk) from Cassyni ( https://cassyni.com ). We both completed PhDs in physics before going on to found Publons and Kopernio, companies that were acquired by -- and became a part of -- Web of Science, a product researchers on HN may be familiar with. It is well known how important academic seminars are for networking, promoting your research, and keeping up with latest developments. But the scale is under-appreciated: by our estimates more than 1 million academic seminars were happening every year. And then Covid came along... As a result many seminar series are now online and recorded using solutions that cobble together tools like Zoom, Google Sites and Sheets. This all more or less works but is painful and time consuming to operate. Our co-founders, researchers at Imperial College London and Texas A&M, experienced this firsthand. With their input we set out to build a tool to take the pain out of organising a seminar series. The idea is that in just a few minutes you can set up a professional looking seminar series and begin inviting researchers. We take care of the tedious process of setting up an online presence and working with speakers to find a time slot that works for them, collect their bio, abstract, promotion and more. We’ve been operating in beta for several months now. You can see some of the seminar series that are up and running on our homepage. These range from your standard departmental series (ABI Tuesday Seminars: https://ift.tt/3mi7RL0 ), to a series about a specific tool for scientific simulations (PyFR: https://ift.tt/3zbj2ZS ) through to a journal that brings in authors to talk about influential papers (J. Comp Phys.: https://ift.tt/2UDmk98 ). Note that you can click on the archive tab of each series to watch recordings of previous seminars. As you can see, these are not just standard departmental seminars; the shift to online has removed geographics barriers, enabling different types of seminar series to develop. What they all have in common is that they are helping communities to form around different kinds of research topics, and they all give you information and nuance you wouldn’t find by reading the related publications alone. On the attendee side, we’ve done some nifty work to integrate with Zoom so the live experience is better (instead of a name in a Zoom meeting you can see the profile of people in the room and participate in a live Q&A: https://ift.tt/3ml5G9t ). In the longer term we think Cassyni can help to make seminars and their recordings a searchable (e.g., check out the slides we’ve automatically extracted from the video and search for “flux” here: https://ift.tt/3D5RkA3 ) and citable (as you can see from the previous link public seminars on Cassyni get a DOI and are indexed in CrossRef) part of the sphere of human knowledge -- a complement to the published literature. We thought we’d share what we’ve built with HN in the hope of getting some feedback about what we can improve. If you are a researcher please do take a look and let us know what you think. And if you’re interested in setting up a seminar series drop us a line (help@cassyni.com) to let us know where you came from and we’ll organise an HN discount for you.

Ask HN: Is there any parents and founders here?
18 by lamida | 17 comments on Hacker News.
Founding a startup is often associated with grinding, long hours and low pay (for a possible high compensation in the exit). I want to start a startup but I feel that I am bit too late because now I am 35 years old software engineer and has a family with 1 toddler and another child is coming in couple of weeks. Is it possible to build a good startup part time (while still working in another company for full time)? Is there any founders out there which still can start and grow their business successfully while raising up children? Should I wait once having enough life saving and once my children a bit older so that I will be more ready for grinding? This is the only link related to this topic in HN[1].

Ask HN: Why does Zoom Desktop examine all processes and arguments?

Looking at syscalls, I see Zoom desktop reads all processes and arguments. [pid 3844872] stat("/proc/1", {st_mode=S_IFDIR|0555, st_size=0, ...}) = 0 [pid 3844872] openat(AT_FDCWD, "/proc/1/stat", O_RDONLY) = 4 [pid 3844872] openat(AT_FDCWD, "/proc/1/cmdline", O_RDONLY) = 4 [pid 3844872] readlink("/proc/1/exe", 0x20c0520, 1024) = -1 EACCES (Permission denied) [pid 3844872] stat("/proc/2", {st_mode=S_IFDIR|0555, st_size=0, ...}) = 0 [pid 3844872] openat(AT_FDCWD, "/proc/2/stat", O_RDONLY) = 4 [pid 3844872] openat(AT_FDCWD, "/proc/2/cmdline", O_RDONLY) = 4 [pid 3844872] stat("/proc/3", {st_mode=S_IFDIR|0555, st_size=0, ...}) = 0 [pid 3844872] openat(AT_FDCWD, "/proc/3/stat", O_RDONLY) = 4 [pid 3844872] openat(AT_FDCWD, "/proc/3/cmdline", O_RDONLY) = 4 ... Why would it do that? Is there any way to prevent it?
