With Starlink, you basically end all dead zones and have full, reliable communications from anywhere on Earth

If you can see the sky, you can communicate

Almost every single day, companies around the world are partnering with Starlink to expand services to their users

It's a system where you can get connected with anyone, making Starlink the most reliable network on Earth

The biggest shift in my security career wasn't learning a new language.

It was learning to stop thinking like a developer.

Early on, I reviewed code asking: "Does this work correctly?"

Wrong question.

Developers build for the expected path. Attackers live in the unexpected.

Every input you didn't validate. Every state you didn't consider. Every assumption you made about user behavior.

That's where the bugs live.

The shift happened when I stopped reading code to understand it and started reading code to break it.

Different question. Completely different results.

The best auditors don't think like better developers.

They think like attackers who understand development.

I once worked at an investment bank where they would give a recognition award to the person that spent all night cutting and pasting commands out of a word document into an SSH terminal.

Scripting these tasks was considered controversial. 🤦🏼‍♂️

Big congratulations to @VulsightSec for scoring their very first paid report on Immunefi.

And it's huge, huge payout.

Well done!

Solidity Interview Q: What is the difference between bytes and bytes1[]?

bytes vs bytes1[] — they look similar, but behave very differently

bytes
- Dynamic byte array (packed)
- Stored contiguously
- Each element = 1 byte
- ABI-encoded as a single dynamic blob
- Cheap in gas (both storage & calldata)

Storage
- Length in one slot
- Data packed tightly (like uint8[], but optimized)

bytes1[]
- Dynamic array of elements
- Each element is its own slot
- Not packed
- ABI-encoded as an array of 32-byte words

Storage
- 1 slot for length
- 1 full slot per element (31 bytes wasted each)

When would you ever use bytes1[]?

Almost never. Only if:
- you need array semantics (e.g. .push() with per-element logic)
- or you’re forced by an interface (legacy / generated ABI)

Have fun.

[Suhail Kakar @SuhailKakar]

why do crypto apps still ask users to connect wallet before they can even explore the app??

let people browse first, then ask for wallet when they actually need it
