How does the Voice And Video Call Work?

This tweet is all about how the voice and video call works on a high level.

Continued in this thread 🧵 [Follow the thread below] 👇

#AndroidDev #Kotlin #Android #Developer
Both voice and video calls depend on how we stream media between the two clients who are connected to each other. So, there must be something that can do the work of media streaming from one client to another client.

For media streaming, we need to know about WebRTC.
WebRTC is a free, open project that provides browsers and mobile applications with Real-Time Communications (RTC) capabilities via simple APIs. The WebRTC components have been optimized to best serve this purpose.

So I've been hearing some good things about @nextjs for some time, and seeing only enhanced it. Also I'm bored, and (arguably?) have some free time, so I'm going to try to remake my blog (with 1 whole post) in next.js just for fun. Let's #Frontend!
To give some context, my only exposure to frontend development is from developing a couple #AndroidDev apps 3 years ago, and I have no experience with JS and hardly any familiarity with HTML/CSS (except making my @firefox look sexier with custom CSS) #BackendDevFrontends
HMB while I spend the next 4 hours setting up and customizing the Ultimate Development Environment™️ for Next.js for 10X productivity™️ #Developer #productivity

[THREAD] 7 RÉALITÉS du métier de développeur ! 🖥

Attention ! Je vais te livrer beaucoup de valeurs d'un coup.

Ce que toi en tant que débutant tu ignores ou imagines à tord sur cette activité !

#web3 #developer

Voilà ce que j'ai appris :

// 1 - On apprend que par la pratique ET au besoin ponctuel. //

J'ai appris #reactjs parce que je devais l'utiliser pour un projet.

J'avais besoin d'une interface.

La leçon c'est qu'il faut juste savoir à peu près en avance quoi sert à quoi.

Pour ça je te conseille de faire de la veille technologique quotidienne.

J'utilise une chouette extension pour me tenir informé de ce qui peut exister pour tel ou tel besoin:

I wanted to highlight an up and coming project on #Tron x #BitTorrent called @dCloudStorage

They are also one of the #Tron Hackathon Winners and a project you shouldn't be missing out on.....🧵
dCloud is a mobile decentralized cloud file storage app utilizing the BitTorrent File System.

It's being developed currently for both Android and IOS users.

It is open source.

If you don't know what #BTFS is, it is basically the equivalent of #IPFS
So, let us compare the revenue models of some storage solutions.

As you can see in the image below, dcloud(BTFS) is half the cost of iCloud and Google Drive solutions.

Dropbox is competitive but has a max limit and you don't pay for what you use.

In the most significant #blockchain upgrade in history, the #Ethereum network is moving from a #proofofwork (#PoW) to a #proofofstake (#PoS) consensus mechanism to confirm transaction blocks, known as “The Merge”

Read more and debunk myths:
1/ The two major upgrades, PoS #consensus and #sharding, promise to deliver fast transaction times with low network costs without sacrificing scalability, security, or decentralization. #TheMerge is Phase 0 of the rollout of the Ethereum 2.0 improvements this year. Image
2/ ‘The Merge’ will replace PoW and the temporary split solution with the more energy-efficient PoS consensus layer, the Beacon Chain. Transaction blocks will no longer be confirmed by solving computationally intensive puzzles. Image

While looking for a way to start her career as a developer, Tuğçenur realized that the solution was obvious - then she landed her first tech job. How? Let’s read 👇
💻 Tuğçenur’s most challenging courses were coding-related courses while studying Electrical and Electronics Engineering - so she thought coding wasn’t for her.
👀 But her perspective had utterly changed when she practiced with Android programming during her internship.

What’s something that every software engineer should try? #developer #webdeveloper #webdev #coder #womenintech #career #careeradvice
Software engineers are makers by nature but they tend to lose this creative side as they begin their corporate careers, be it at startups or fortune 500 companies. Some say you can’t have everything in life — you can’t be an employee and an entrepreneur.
But I challenge that, and I say, you can have you cake and eat it too. Just because you’re working for someone doesn’t mean you hand over your creativity. There are many ways to create as a developer, aside from your full-time job as an employee.

Yesterday @SpyWolfNetwork had an #AMA with @PoorQuack. It turned out to be a session full of valuable information, which deserves to be spread further around.

So here we go! Slightly edited here and there to save some space. Enjoy the ride!

$POOR #PoorQuack #CryptoNews
Intro by Gyro Gearloose, [9-3-2022 19:08]:
@PoorQuack is all in one #Ecosystem where we are attempting to make it easier for #investors to #research crypto projects and avoid #scams whilst allowing holders to earn via #DeFi.

$POOR #PoorQuack #cryptocurrency #Web3 #Metaverse
We also have entered the #NFT space with our own #NFTcollection and all of these will have #utility within our own #Ecosystem.

The #NFTmarketplace V2 will be released soon and this will allow third party #NFTs like the #OpenSeaMarket.

HTTP Caching, RPC Protocol, Browser’s developer tools

As part of the WEB3 developer roadmap.

Caching :

As yesterday mentioned our browser tries to check the local cache first to resolve DNS.

Similarly, there are CDN services that provide complete websites from their cache using the HTTP protocol.…

RPC Protocol :

Normally our programs and processes run locally in our system, but there are some protocols that support execution in a remote system. Such as RPC protocol, which makes it easy for the peer-to-peer networks.…

Is Blockchain a fad? Can Web3 problems be solved? Share your thoughts on this⬇️


#web3 #developer #crypto #Blockchain
A) Development. Blockchains have different architecture and underlying tech. To put this in perspective, you can write smart contracts for Ethereum in a language called ‘Solidity.’ For a similar development in Solana, one needs to learn ‘Rust.’ For Tezos, it is ‘Michelson.’
B) Interoperability. The ability of one Blockchain to talk to another. Currently, due to lack of interoperability, assets on one Blockchain cannot be used on the other.

Like many others, I have been observing the #ScrumMaster market over the past 12-13 years. That said, the qualification possibilities have grown dramatically. The general skill of a Scrum Master too. But there is something wrong.
Average day #rates for Scrum Masters rather went down, instead of up. Large companies claim, they can get a great Scrum Master at EUR 500,- to 600,- (Western European ranges). And they miss one point: such a person would be plain stupid joining them!
Let's be frank. The first Scrum Master in the world was an experienced manager. The idea for this role was never a simple one. Bad implementations made it simple (like becoming a team secretary). But to me a Scrum Master is a skilled #organizational #developer.

- What is it?
- Who are the people behind it?
- What are it's future plans?
- Why do I think it's essential?

Here's my write up to give insight into this hot, trending project. As always #DYOR and #NFA.
2/19 #LEONICORNSWAP is a #BSC advanced AMM (#DEX) which seems focused on #Security as it's prime objective, with features such as #lottery, #NFTs #marketplace, #IDO (IJOs), #Staking and many other features that are yet to be announced. (See Road Map)
3/19 Lets delve deeper into the objectives of the #DEX. As I previously mentioned, #Security seems the number one priority, audited by @hackenclub and @certik_io. Something we are all unfamiliar with on the #BSC network is the common #RUG pull security issues with #IDO (presales)
