Why do some of my YouTube videos are either too short or pixelated?

☝️ is a good example of an SD type of video on my channel. And the main reason behind it is my internet connection which doesn't process a YouTube upload over 100Mb (yup, it takes almost an 30 mins for 100Mb from time to time). Due to the lockdown I can't

20,000 nominators on Polkadot update. OUCH!

Oh oh. This is not an update I was waiting for to be honest. Since very recent there will be a cap of 20,000 nominators on PolkaDot at any time. I believe it should be solved as soon as possible because: 1. I don't like the fact nominators are

Crypto fall yesterday... BUY

Yesterday marked the day of the lowest point of crypto I've seen in a while (in terms of a drop). Remembering I purchased a good amount of dot for nearly $45/DOT - OUCH! But it was also a good time to buy when it dropped to a record $18

Finance

Never lose money

The temptation of selling on loss when you discover another opportunity with a perfect timing "now" is really tough. I still remember a moment when I invested some capital in a company A, when after a couple of months the value dropped by a good 20%. At that time a

4+ years without Facebook

Best decision. Ever. I'm still wondering why people use Facebook and other social media. Seriously. I get the idea of being connected to a close circle of people, but it is definitely not the ideology of the platform. Facebook is full of fake and egocentricity, impostor syndrome, jealousy and misery.

Geek is chic

There are people who make things, and there are people who sell things. Somehow, historically, in a majority of companies/corporations there is a segregation of sales/marketing/business and development. Most of the time there is a requirement/plan coming out from business with a mighty deadline which then

Why do you need to stake on Polkadot?

Staking is a term when you lock your coins and receive daily "dividends" as a reward. This principle applies to Polkadot too, you can lock N amount of coins and every day receive percentage of what you locked up. Since Polkadot has NO token supply limit (there can be an

Thinking about PolkaDOT 😍

Crypto here, crypto there... Everyone shouts about Bitcoin retirement and $11M CryptoPunk sale on Ethereum network but primarily forget about innovation and blockchain 3.0. If you pay for a $2 coffee with Bitcoin your transaction fee would be $400-500 (variable of course) and take so much time to process

Development

Please don't make complex projects on Lambdas.

No, seriously. I've been talking about it for some time, but here we go again: If your project requires substantial codebase, test coverage, complexity + expected to live for over a year - I would skip Lambdas (or any other serverless-tightened approach) 100%. The main reason is being dependant on framework.

Rust is a piece of cake

I've been always aware of Rust language, however never invested enough time until had to try !ink smart contracts for Polkadot... which are written on Rust. Honestly, I didn't expect such a good personal vibe towards the language. https://doc.rust-lang.org/book is a situation when a human-readable guideline

Using the Nano Ledger X. Is it worth it?

Crypto is very exciting. And one of the most exciting things about crypto currency space is a full anonymity. What does it mean? When you "create/generate" your "wallet", it simply basically pics up a random private key from a huge space(really huge space) and creates a public key

Intro to container-optimised Google Cloud VM instance
