MAKE SURE to use secret manager with a proper permission to protect yourself from actual database deletion

https://resend.com/blog/incident-report-for-february-21-2024
I am sure Resend has learn a LOT of lessons from the backlash they are getting from all of the twitter posts.

1. Email Leaks
2. Multiple Downtime(LONG HOURsS)
3. DATA LOSE


On Serious note the reason why a lot of rules on backend developments is because almost all of the requests are soo vauable you can't even afford to lose one. i am not saying Resend Team is bad or not i am just trying to state the fact that this kind of incident really should teach us the best from other experience.

Am sure Resend is losing a lot of customers right now, think of it you got a really nice SAAS and your user cant even register due to a simple Email failure.

One of the strongest traits from Uber Team i have learned is to always have a backup even for big stuffs. One time AWS have a downtime but Uber Team are so smart they had a backup for their service discovery and were not affected that much quickly they are already mediated the issue from uber side and aws was still down at the time.

WELL i hope GOOD LESSON LEANRED TODAY

Many developers are so good in their world but they fail to merge their world to the one we live in.

We learned C/C++ while in campus thinking it is great language, then

we got introduced to other languages like JavaScript and Python then

we changed our mind that C/C++ is dead, then we moved on after sometimes we changed our mind to C/C++ was the best till to this day.

And we thought Carbon is c++ killer ๐Ÿ˜„

I admire Rust but fact still here, c/c++ is not gonna be dead anytime soon ๐Ÿ˜‚.

So learn it well now.

Honest opinion, How many of you really understand the below concepts really well.

1. Threading 2. Multiprocess 3. Async programming I am not asking only the concept but work with them in application leve. some of the concept doesn't apply to some PL.๐Ÿ˜‚

When you write your application make sure to keep in mind that it can be tested and below points

1. Have a way to override some important variables like database sessions so that you can have test_sessions
2. Make sure it can be emulated[Some services are difficult but you might want to find a way]
3. Write unit test as early as possible or you will be in a lot of procrastination cycle
4. Setup adhock script from the start if you can like CICD, testing, PR templates and others.
5. Use container if possible it will save you a lot of time in setting up production apps and other environments.
6. Don't over complicate your application logics Keep it Stupid Simple (KISS)
7. Don't use float to represent money you will going to lose a lot of money. either use String or have a Decimal type with a precaution on precious part

๐Ÿ˜ Next month, channel owners on Telegram can start receiving financial rewards from their work.

Broadcast channels on Telegram generate 1 trillion views monthly. Currently, only 10% of these views are monetized with Telegram Ads โ€” a promotion tool designed with privacy in mind.

In March, the Telegram Ad Platform will officially open to all advertisers in nearly a hundred new countries. Channel owners in these countries will start receiving 50% of any revenue that Telegram makes from displaying ads in their channels.

To ensure ad payments and withdrawals are fast and secure, we will exclusively use the TON blockchain. Similar to our approach with Telegram usernames on Fragment, we will sell ads and share revenue with channel owners in Toncoin. This will create a virtuous circle, in which content creators will be able to either cash out their Toncoins โ€” or reinvest them in promoting and upgrading their channels ๐Ÿค‘
