Most people thought flat data center networks would never work at hyperscale.

The @awscloud team figured it out.

Resilient Network Graphs are a completely new network architecture, now live.

33% better throughput, 40% less network power.

The right kind of ambition is to compete against yourself. To be the best version of yourself.

[Matt Garman @mattsgarman]

We're the first cloud provider to offer @AnthropicAI 's native Claude Platform directly through customer accounts. Teams get access to the full platform, from Managed Agents to code execution, using the @awscloud credentials, billing, and audit controls they already rely on.

No new vendor accounts, no new systems. https://t.co/I9w1ypzhXH

The Quick desktop app is here, and it’s compelling.

Connects to your email, calendar, Slack, local files, and several other apps to flag important communications, retrieve and summarize info, make recommendations, send communications, and create agents that do work you used to have to do yourself. Gets smarter and more personalized the more you use it.

Been using it a lot recently and is changing how I work. It’s allowing me to use applications like my inbox more like an archive, and Quick as my personalized, prioritized, productivity hub that can multi-task various needs.

Still early days, and a lot more coming, but excited for folks to start using it to make the undifferentiated work so much less complicated. https://t.co/UtuGTDx4gT

Totally agree. Sometimes the biggest risk you take is not taking risks. Now feels like that time. Predictable low variability path to slow decline or thoughtful risk taking

Best advice I got in my 20s: Nobody cares. When you’re winning, nobody cares. When you’re losing, nobody cares. It doesn’t mean nobody loves you, it just means nobody cares about your life as much as you do. You are in control. It’s on you. Nobody cares. Go do the thing.

For those who are interested, Function Health offers a wealth of interesting health-related data (could make a good gift for the health-data-intrigued in your family or friend circles).

1/ Fusaka is coming December 3rd.

Ethereum’s next major upgrade shows that the network can grow to meet global demand, without compromising on decentralization or permissionlessness.

Whether you’re a user, builder, institution, or operator, here’s how Fusaka will impact you.

[Zun @Zun2025]

Ethereum Fusaka upgrade will go live this week and here is what will change in the upgrade :

1. PeerDAS (Peer Data Availability Sampling) : EIP-7594

so before explaining this, you must need to know about blobs. so think of blobs as temporary storage lockers for L2 networks.

when we use dapps on Arbitrum, Optimism or other Layer 2s, our tx data needs to be posted to Ethereum for security, blobs are special containers designed exactly for this data to store temporarily.

Before Blobs (Pre-Dencun) :
▫️L2 Transaction Data stored in calldata
▫️Cost : $$$$ (Expensive, Stored forever)
▫️L2 fees : $1-10+ per tx during congestion

After Blobs (Post-Dencun) :
▫️L2 Transaction Data stored in BLOBS
▫️Cost: $ (Cheap, Temporary storage)
▫️L2 fees : $0.001-0.10 per tx

So, in DAS, Instead of downloading all blob data to verify it exists, nodes sample small random pieces.

If enough random samples check out, the full data is statistically guaranteed to be available.

-----> Analogy :

Let's say you want to check pizza quality of any shop, here is what happens with and without DAS

Old Way (Download Everything) :
▫️Eat the entire pizza to verify quality
▫️Time : Long
▫️Stomach : Full
▫️Cost : Expensive

New Way (Sampling) :
▫️Take 5 random bites from different slices
▫️If all 5 are good → Pizza is probably good
▫️Time : Quick
▫️Stomach : Room for more
▫️Cost : Cheap

-----> In Blockchan terms :

Before Fusaka :
▫️ Every full node must store all blob data from L2s
▫️ Storage : 100% of blob data
▫️ Bandwidth : high (downloads everything)

After Fusaka :
▫️ Each node stores only 1/8th of the blob data
▫️ Full blob data can be reconstructed from any 50% of the network node
▫️ Bandwidth : ~80% reduction

Impact : 8x theoretical scaling without increasing node requirements

2. Gas Limit Increase to 60 Million : EIP-7935

have u ever noticed that some blocks contain 150 txs , some block contains 400 txs?

this is because of the block gas limit, each block has max cap of gas limit, if there is any txs with less gas limit, then u will see many txs in that block.

on the other hand if there are tx with more gas usage, in that case, you will see less txs in that block.

Before Fusaka :
▫️ Block Capacity : 45 Million Gas
▫️ Transactions : ~1,500 simple transfers
▫️ Congestion : Common during high activity

After Fusaka :
▫️ Block Capacity : 60 Million Gas
▫️ Transactions : ~2,000 simple transfers (+33%)
▫️ Congestion : Reduced

3. Transaction Gas Limit Cap : EIP-7825

Fusaka introduced gas limit cap per tx to prevent DoS attack.

Before Fusaka :
▫️ Single Transaction Could Consume entire Block's 45M Gas, for example this tx : https://t.co/aATMpVE8vL used all the entire block gas and thus there were no other tx in that block : https://t.co/M8fZVLUAva
▫️Risk : DoS attacks possible

After Fusaka :
▫️ Maximum 16.7M Gas Per Transaction (2²⁴)
▫️ DoS protection enabled
▫️ ~3.5+ large transactions per block minimum

4. secp256r1 Curve Support : EIP-7951 (Precompile)

This upgrade also introduce native mobile hardware security.

Before Fusaka :
▫️ Signing method : Only secp256k1 (Bitcoin/Ethereum)
▫️ No native mobile secure enclave
▫️ Hardware wallets need special chips

After Fusaka :
▫️ Signing Methods : secp256k1 (Original) + secp256r1 (New)
▫️ iPhone Secure Enclave supported
▫️ Android Hardware Security Module supported
▫️ FIDO2/WebAuthn compatibility
▫️ Hardware-backed mobile wallets

Have you ever seen a colleague complain about the way someone does something behind someone's back?

At Coinbase, we don't believe in political behavior. We've found the best way to stop this is to celebrate openly discussing problems as part of our culture.

You have to take the time to put it in writing, which forces you to fully think through and lay out the problem, and then propose your solution to fix it. This either solves the problem, or helps the team get re-aligned on why it's the way it is.

This is how you can actually be constructive and make real progress, as opposed to just complaining about something.

@JonathanLittle @bigotry_watch @altcap Thank you! Curious if they require prescription or you were able to do without prescription.
