Bookmarklet can help

video.currentTime = video.duration

It also is very disheartening to see few launch HN's not even getting 20-30 up votes.

I can't even dare to imagine how demotivating it can be for the founders. I really wish YC can cater to as many startups as it can and hope the reason for this is not the growing batch sizes.

Do you mind elaborating pls,

From happiness to spending quality time socially feeling important is basic need for any human being, pls correct me. Never been to Detroit but seen streets of SF and India so I thought I have enough sample size.

First of all Thank you for thinking about y/our community,

Here are few thoughts,

Mornings/evenings. Have yoga camps it need not be physical yoga, there are quite an extensive range of breathing exercises which can be done just be sitting

Local ppl upgrading is important, (young ppl learn and leave) it's important to educate the existing community, Conduct bootcamps, there is incredible content online, get together, have learnathons around them and help each other finish you don't need any expert to get things kickstarted

Evenings, identify local talent and organise cultural programs

Someone suggested buddha, go one step further have nothing, have an empty space where only rule is no one talks(teach meditation if possible but make it a knowledge not religion based as it leads to groupism)

The no talking space and cultural performance space can share the same compound, you can come up with a cool name for that, something where a milleneal can say I performed at that.

There is happiness in giving, organize volunteer activities like cleaning, planting trees etc etc

You can use this in Safari https://github.com/ai/audio-recorder-polyfill

https://github.com/GoogleChromeLabs/webm-wasm

Safari doesn't play webm files two options for that

1). you can convert webm to MP4 with or without re-encoding(will be faster) using ffmpeg or ffmpeg-wasm (within browser) https://github.com/ffmpegwasm/ffmpeg.wasm

2). Another option is play webm directly using wasm https://github.com/brion/ogv.js

Couple of other alternatives https://github.com/patr0nus/DeskGap https://github.com/neutralinojs/neutralinojs

Like many pointed out electron may be a beast but few important things like system tray, start on boot come inbuilt with electron.

https://supabase.io/ is a YC backed open source realtime db. You may find it relavent for the transport layer

Congratulations on the launch :)

Congrats Ish on the launch.

Considering you are building on top of zoom et all, you can try making your bandwidth costs close zero by leveraging the data feed of Zoom or Google Meet itself by being a browser extension

We did they same and are able to enhance learning experience on top of zoom/meet quite a bit by tinkering with the video,audio feed being fed to them without putting a hole in the pocket(due to bandwidth costs), in turn gains being translated to the customers and being able to add enhancements super quickly.

Congratulations once again and Good luck, from India

Not exactly as powerful but something similar and that can run on a browser, opening up to a lot of creative applications, handpose powered by tf.js(similar model exists for tflite)

Demo: https://storage.googleapis.com/tfjs-models/demos/handpose/in...

Repo: https://github.com/tensorflow/tfjs-models/blob/master/handpo...

Tflite model: https://github.com/google/mediapipe/tree/master/mediapipe/mo... there is lighter 2d model as well

Ask HN: Usable energy why only electrons

Hello folks, Is generating electrons the only way to create usable energy( like electricity )For example nuclear reactors which generate neutrons and heat is in turn via stream or molten salt used to run a turbine and magnet and the routine stuff to generate electricity, cant we just utilise the neutrons?

Yes I am so sorry for the confusion.

When we breathe, first the lungs fill up, as adults we exhale at this point. We should continue breathing until full lung capacity i.e until it pushes the diaphragm down which in turn pushes the stomach giving a sense of pot belly, if you have a pet or a child notice their stomach while they breathe.

There seems to be little confusion about chest/stomach breathing. We draw air with lungs which reside in the chest, its just that we are training our body to take deep and longer breaths we get a feeling that we are drawing with stomach

As PG says one needs child like curiosity, we need to child like breathing :)

Lot of people tend to have respiratory failure before situation gets worrisome and breath exercises are a definite way to help your body do what a ventilator does

In yoga asanas, there are few breathing exercises that existed in ancient India and I myself can attest to it that I was able to overcome lot of allergies practising it,

Here is a resource to follow along. https://youtu.be/iUKjuni-6l8 starts at 9 mins and goes on for 15 mins or so

And yes everyone breathes the wrong way, we pull in stomach when inhaling which is supposed to be otherway round, I know it's surprising to hear that we are breathing wrong. if you want the proof just notice a child breathing that's the most natural form of breathing

If you are looking for keywords to look up, the are anuloma viloma & kapalabathi.

Stay safe, stay healthy.
