Neon met a 16 yr old boy in Monaco that owns a 1 of 1 Bugatti Chiron super sport worth over $7 million and a pagani worth even more 😳

The crazy thing is they both have a license plate that costs more than the cars itself, capitalism at its peak 😭🔥

The level of Wealth exhibited in Monaco this week is nothing short of astonishing, this is a $5 million Bugatti parked untop of $35 million Yatch floating next to two Mega yatch 😭

What do I do to achieve this level of wealth? 😩

Ever committed a checkout change too early?

Create a git alias for a quick undo:

git config --global alias.undo 'reset HEAD~1 --mixed'

Then:

`git undo` rolls back your last commit but keeps the changes staged.

Helpful when you spot one more fix before opening that payment integration PR.

SpaceX has almost finished writing V1.0 of an in-house AI training stack in C that exact-maps to 220k GB300s with 800G NICs, making heavy use of pipeline parallelism and getting as close to bare metal as possible.

The potential speed improvement vs JAX for large training runs is over an order of magnitude.

As a Principal Backend Engineer with over 12 years of experience, I can tell you quite certainly that if you're still getting rejections in system design interviews after good efforts, I think your fundamentals are not strong...

Dedicate 2-3 months to mastering these design fundamentals, then practice designing a few systems(and do plenty of mock interviews).

@mambowevarozvi @BBCAfrica I already said this, "92% of Chinese speak the same language in as much having SEVERAL DIALECTS". In Africa am not sure but I don't think there is a country with several tribes and dialects but one common dialect over the others and you know it infact our tribalism won't allow.

[Daniel @danc_O]

@mambowevarozvi @BBCAfrica 92% of Chinese speak the same language in as much having several dialects. That is how it works moron, languages however much it represents us also adoption is what defines if it makes sense to argue of how good we should promote it. If you think otherwise tweet in Yoruba then

[Daniel @danc_O]

@mambowevarozvi @BBCAfrica Can you explain QUANTUM COMPUTING in your indigenous language. In as much as I don't support him but don't just say anything to justify your point. Understanding English is as good as understanding your indigenous language for the essence of civilisation and many other reasons

[Daniel @danc_O]

@stimasacco I would like to know, why does it take one to physically visit your branches for a PIN or ACCOUNT reset incase of login issues. Very inconveniencing yes, but is it a system design issue or a regulatory issue.

[Daniel @danc_O]

It baffles me that @stimasacco charges for balance checking for each of my 3 accounts.
That’s a single API call on M-pawa. Why charge me 3 times to know my wallet balance?
I can’t transact without checking my balance, so I pay balance fee then a transaction fee. That's excessive?

@stimasacco Also, why must I physically visit to reset an M-Pawa password or activate my account? Many digital verification tools exists. This inconvenience is unnecessary guys.
