RomanPushkin··on Show HN: 1-FPS encrypted screen sharing for introverts
See updated docs for Windows users: https://github.com/1fpsvideo/1fps?tab=readme-ov-file#windows...

Please understand the Windows toolchain is often broken, and binaries are preferable. I will roll out binaries soon for all platforms. I also noticed some cursor coordinates issues on Windows machine (I have high resolution). I'm wondering if you have any issues with that as well.

Good news is that there are steps to workaround and we're aware of these issues :) I guess check back later, I hope we gonna fix it soon!

This is what I sometimes do with a friend of mine: WhatsApp phone call and a simple screen sharing between my laptop and his PC.

It's not only a matter of bandwidth, but a matter of CPU utilization. I've tried to feed screenshots to ffmpeg and other tools, and it's just... unusable. It works, but consumes way too much resources. At least on my computer (MacBook 13-inch, 2019).

So from on side you have CPU utilization, from the other - network. Network is cheap, but encoding is expensive. This is my thinking at least. I don't have proof - only local experiments, but it's a really good idea to start measuring this.

I also have other ideas in mind on how to scan the screen and send only parts of the screen that have been updated. Probably if I send only a half of the screen, it will beat the video encoding in terms of network. The diff algo should be very fast though, since we're dealing (in case of 1280x720) with 1280x720=914400, 914400*4 = 3.49 MB info processing in 1 second.

Also, curious to hear about video encoding efficiency vs 60x JPEG creation. Is it comparable?

RomanPushkin··on Show HN: 1-FPS encrypted screen sharing for introverts
oh, I like it actually! I had idea to scan the screen with 5-10 pixel sparse 100x100 matrix at the point where the change has been found previously to detect a possible screen change.

Thanks, you have my promise that for every major use case there is going to be a fix. Feel free to check out at a later time if has been fixed or not. I appreciate the feedback
RomanPushkin··on Show HN: 1-FPS encrypted screen sharing for introverts
I'm happy to hear that. I've just open sourced the server part, so you can play with it a little bit more! I will improve docs over the time, so it's easier to follow.
RomanPushkin··on Show HN: 1-FPS encrypted screen sharing for introverts
That's pretty cool and this is exactly why I am here :) To have this kind of advice. I'll implement these changes as soon as I can.
RomanPushkin··on Show HN: 1-FPS encrypted screen sharing for introverts
There are many. For example, you're leaving your home computer and going to work. Save a link and see what's going on there. The same for remote desktops.

Another use case if when you have a long-running meeting, and still need to share. I found I sometimes just do not sit and listen for those 1-2 hours meetings, but prefer to code.

And for those of us who just don't like audio, like myself. I have many students who I am willing to help, but I don't wanna get audio-involved. My voice chat is not a very parallelable resource.

Thanks, I will update docs. "robotgo" has some issues on Windows, I am currently looking into some of them.
RomanPushkin··on Launch HN: Airhart Aeronautics (YC S22) – A modern personal airplane
No offense, but:

> The only real single point of failure is the engine

Sounds like a dangerous statement to make. There is multiple more: software, flaps/alt controls, pilot failure, etc.

And also "lever sensor fusion math" - personally being software engineer I am not a big believer in "clever"

I also wanna mention that I really like the idea, and looking forward to where it gets you; hopefully such skeptics like myself will have enough trust into what you're working on!

RomanPushkin··on Meta has run hundreds of ads for cocaine, opioids and other drugs
There is no euphoric effect or any other effect that makes it recreational. It's more of a self-reflection tool that helps to breakthrough into the perception of things that are so much different. And it helps to break bad habits actually: alcohol, tobacco, being aggressive, etc. Also, because it's not euphoric, it is not addictive as other drugs (read: alcohol and above).

> “DMT,” a psychedelic drug.

I would argue that. It's probably the least offensive thing, compared to alcohol you can buy everywhere. DMT and other entheogens are far less harmful than alcoholic drinks available. It's confirmed by many academic papers, and DMT is not something people use for recreational purposes.

Moreover, some of these "psychedelic drugs" are used by people who have serious illness, wether it is life-threatening like cancer, or all kinds of PTSDs. It is very well known that these "drugs" help to prevent suicides, and very often it makes people's lives less miserable.

While I agree with the narrative, and totally against unregulated drug sale, I can't say WSJ put a lot of thought into the article posting a picture of DMT powder as the main evidence to make entire article look more scary. Average Trader Joe's with vodka looks many times scarier to me.

RomanPushkin··on I prefer rST to Markdown
No offense, but when I downloaded a sample PDF I expected to see a better formatting. The file is little bit clunky. I think it's not a failure of a formatter, but the design in general. The default markdown formatter in Leanpub works good enough, to a degree when I don't need to think about it.

So, while I understand all the good parts, I am still kinda not convinced it's a better option looking at the final product.

RomanPushkin··on Finding a random seed that solves a LeetCode problem (2023)
The same can be applied to a stock market. I am a big fan of looking into historical data, and I was using WealthLab for quite a while.

One of the funniest things is when you find "strategy" that performs best over one year by making from 50 to 100 deals. But don't get fooled, it's just a random parameters, and when applied to the next year or years, you won't get these results, of course.

So you're getting reliable results only when you can reproduce your success (no matter what it is) consistently.

True. I'm getting offers I was getting back in ~2018. I will stay here anyways. There are some ways to mitigate that shrinking, which are pretty well known...
RomanPushkin··on Daily cannabis use overtakes drinking in US first
my manager from Atlassian used to fart a lot, standing by his desk. He even had no hesitation, it wasn't once or twice. I was wondering why nobody was willing to sit next to him when I just joined. I've learnt it the hard way. He moved now to Australia fortunately!
RomanPushkin··on Daily cannabis use overtakes drinking in US first
Try mushroom matcha (ryze brand). I used to drink tea, a lot. But now I am only mixing mushroom matcha with a small spoon of raw organic maca powder, and a hot water. Don't add maca in the evening, it might affect your sleep hours.

It's been pretty much my drink for the last couple of years.

RomanPushkin··on OpenAI departures: Why can’t former employees talk?
They don't talk publicly, but they're almost always OK if you're friends with them. I have two ex-OpenAI friends, and there is a lot of shit going in there. Of course, I won't reveal their identities, even in a court. And they will deny they said anything to me. But the info, if needed, might get leaked through trusted friends. And nobody can do anything with that.

Can you write a blog post "What I wish I knew before going to MIT/college"? I find the reason you made this app very intriguing. I want my son to know thing you've explained here. If not - it's not a problem, thanks for your work! Best of luck!
RomanPushkin··on Show HN: Glossarie – a new, immersive way to learn a language
Can you add one Russian book with translations into Spanish? I wanna give it a try. Maybe a couple of chapters would work. This book is my favourite since I was a kid: "magician in town yuri tomin" (Russian: "шёл по городу волшебник юрий томин").
RomanPushkin··on Uber to pay $272M to Australian taxi operators
My friend drives Red Cab in San Francisco. A couple of weeks ago he charged ~$500 from SFO airport to San Jose (taxi meter price). He informed the passenger, since he thought it's going to be too much for her, and gotten the response he shouldn't count her own money, and should just drive there, lol.

RomanPushkin··on Framework Laptop 16 Review
> Macbook Pro keyboards to be "fine," but I'm curious if I am actually missing out on a better experience

Yes, you are missing a better experience. You might try out Bluetooth X201-like keyboards built by enthusiasts from China, if you can buy them. I tried to contact with no luck though.

But it can be a good DYI project, if you have one for sale, let me know.

Here is the link https://www.taobao.com/list/item/615448425938.htm

They 3D-print the body, and use keyboards from Thinkpad laptops.

> How far are you getting with these updates?

I can run Slack native app and the fan doesn't kick in!

Kidding, but I have Slack running, and containers, and IDEs. Everything. My CPU is pretty decent, 64GB RAM, 2 SSDs, 1TB each. This is modded X201 from enthusiasts from China. These laptops are somewhat niche, but you can buy them.

You will run all the software you need, and even more. The only downside is battery life, I hope we'll have new types of batteries some time soon, so it won't bother me too much.

RomanPushkin··on Framework Laptop 16 Review
Yes, through enthusiasts from China. They make their own motherboards and install modern components. There is no warranty though, and you need to wire them funds, there is also no returns. It worked for me though. I have 64GB ram, 2 SSDs 1TB each. It's mostly silent after I configured things in BIOS. The battery life still sucks.
RomanPushkin··on Framework Laptop 16 Review
I wish they deliver good keyboard as well, like Thinkpads X201 or similar have. I am happy owner of modded X201 with updated screen, motherboard, and so on. It's not on a cheap side, but I'm happy to pay that price _only_ for the keyboard option. It's so cool. Folks back then knew what was important.

RomanPushkin··on Ask HN: How many of you are consciously downsizing your devices/going retro?
Driving my 1972 VW. I've learnt a lot over 2+ years. Did some repairs myself. For example, starter didn't crank at one point of time. Removed it, disassembled, cleaned, installed back. Works. Installed new, programmable distributor instead of old one. Did some basic electric work.

I think it's essential to do this kind of stuff, so you won't get dumbed down by "you don't need it" narrative one day, finding yourself helpless and dependent on "experts".
