Everything that's wrong with modern software can be summed up in two words:

"Unnecessary Complexity"

Programming languages, project structure, build systems. libraries, performance, team structure, all suffer from this.

Unnecessary complexity affects most human activities. Just look at politics and the legal system. We try and solve every problem by adding something new which just adds another set of problems. But programming has a particular problem because programmers usually self select for enjoying complexity. We enjoy being able to understand something complex and get it working. We are engineers of probably the most complex structures humans have ever created.

Because of this it's our job to fight complexity where ever we can. There will always be complex problems where we do need to flex our brains, but everywhere else we need to strive for simplicity. Complexity is the enemy of good software.

We did it again.

We are thrilled to announce that ChainLight has won @defcon 32, the Olympics of CTF.

This marks our 8th victory and the first time any team has won 3 consecutive years in the DEF CON history.

🧵For those new to ChainLight, here’s a little thread about us:

@pr0v3rbs 1. Its PAC used QARMA, not xxhash
2. triangle.bin and password_for_hash.bin had the same circuit
3. The circuit is a 8-bit 2-address-code computer with 4 registers, no RAM, Harvard arch.
4. You extract LUT for type-0 gate from PAC code, and reverse the ISA to decode program

✍️ Who has ownership of smart contracts?

📌 Our team wrote an article exploring the concept of smart contracts and ownership, briefly delving into its relationship with governance. 👇

Congrats to HyungSeok! His work is accepted to IEEE S&P! He now became a security grand slam winner; He published papers as a first author in CCS, NDSS, and Security and now got S&P. It was a great collaboration with @theori_io.

@cometkim 요즈음은 OS 업데이트의 일부로 자동 펌웨어 업데이트를 수행한다고 하네요.

경력이 길고 짧고를 떠나서 사람의 능력치는 다 다르다. 일을 못하는 사람에게 윽박지른다고 상황이 좋아지지 않는다. 좋은 말로 설명하고 그 사람에게 맞는 일을 분배해주면 대부분의 사람은 따라온다. 이 말을 들으면서 몸에 소름이 돋았다. 그리고 조금 부끄러웠다.

@pr0cf51 This is called a partial move. Yes, it's possible to drop individual fields of a composite type as long as the (outer) type doesn't implement Drop.

MMM takes 1st at @defcon CTF! Had a great time playing with our friends @maplebaconctf and @theori_io as @mmm_ctf_team! 🍁🦆🗝

Great job to Katzebin, StarBugs, and all the other teams! And thanks to @Nautilus_CTF for organizing!

Also wanted to plug a post from @kmkwesteinde about how Shopify has pursued a modular monolith: https://t.co/NQCHee6Pn2

Worth considering when scaling an engineering org. You get the component boundaries, without the complexity of additional services.

A code formatter has its own share of complexities which are not present in e.g. a compiler.

As rapporteur on Europe’s new cyber security legislation NIS2, I’ve put forward an amendment to demand every EU member state to introduce safe routing protocols (RPKI for example) so that these BGP Hijacks are no longer possible. Now everyone understands why (2)
