A beautiful tabi cat looking straight at you, with light grey hairs, a darker, almost black M pattern on the forehead, and fluffy ear tips.

Tired of reading about AI, quantum safety, politics, and other doomsday material? Just post your cats. I sure need more cats in my timeline and so do you.

A screenshot of code that reads: /// 01 -> compressed infinity point /// the "uncompressed infinity point" will just have 00 (uncompressed) followed by zeroes (infinity = 0,0 in affine coordinates) isCompressed := (input[0]>>7)&0x01 == 0x01 if !isCompressed { return nil, fmt.Errorf("uncompressed point cannot be decompressed") } isGreatest := (input[0]>>6)&0x01 == 0x01 // we clear both bits input[0] &= byte(0b00111111)

Listen folks, I've seen a lot of code, I've seen code you wouldn't believe, but this, this right here, it's truly the best. The greatest, I tell you! We have the greatest coders, they write the greatest code, nobody does it better. It's tremendous, it's fantastic, it's yuge!

I just had to pull out my copy of "The Arithmetic of Elliptic Curves" by Silverman because a paper had the AUDACITY of referring to it without recalling the definition, and I absolutely loved the experience of fishing the definition in an actual paperback🤣 Glad I had it, tho.

We heard you all like random cats, so here's our random cat of the day. Chosen uniformly at random with verifiable randomness from our quicknet VRF round 20993439 among all the 1 available cat to draw from.

Doing too much low level cryptography.

Here's an advice for you if you're discussing partnerships with vendors: stop wasting the vendor's time with idle calls if you've already picked another vendor anyway because you're "locked in by your investors' wishes". Not a good look for your team to do so.

Just refreshed the whoami.filippo.io database.

If you are one of the “lucky 10,000” who’s never heard of it, try

$ ssh whoami.filippo.io

Looks like my team has ensured I wouldn't be pushing any code to prod: they rustified it all, leaving me with just a few basic web backends to play with in Go. Not sure if I should be glad or sad as a founder that I cannot properly contribute to our codebase anymore 🤣

A masked OG dev with the drand logo and brand on his mask, doing a Sssh sign with his finger in front of his mouth.

BRB, putting the G into OG devs by sneaking commits into our feature complete legacy project...

Not me doing almost the same joke every time I am in Bern train station, no, no...

A picture of a train with a BLS brand on it.

Who's complaining about the speed of BLS again?

A speaker showing weird functional code in Go and pointing at a screen titled "The untyped Y Conbinator", with a Gopher in the background.

@gopherconeu.bsky.social teaching us what not to do in Go 😂

I'm sorry I didn't shout during the panel to tell everyone about FIPS in Go crypto when it really would have been needed! There was a question that would have been the perfect opening for it.

In case the "plaintext as a default and e2ee only for private chats nobody actually uses" wasn't enough of a red flag to you... I still cannot fathom how UX could actually justify Telegram adoption by the entire web3 communities, who are supposedly more likely to be concerned about privacy 😵‍💫

The door of an elevator with a projection of a password prompt pop-up with some German text.

That feel when your elevator has a password prompt on its door...

You mean the Quelloffenegemeinnützlichkeitsspätvergütungszuschussinitiativkonzept?

The German government is better at funding open source than the entirety of the web3 industry put together. Change my mind.

No lies told.

Here's a statement once said about gold that will never be said about Bitcoin—even by maxis:

> "Sometimes that yellow color just doesn't match the richness of celluloid or pearlized resin."

You know why? Because you can’t make fountain-pen nibs out of Bitcoin, duh!

TFW you've just resized your fully-encrypted root partition thanks to LVM and cryptsetup without even rebooting, while also increasing the Argon2id parameters. 🤩 Well, if I'm offline tomorrow, you'll know why I guess.

Are you a small, independent game studio with big dreams?
Fair loot drops, balanced PvP, and unpredictable worlds shouldn’t be hard.

Randamu gives you plug-and-play, verifiable randomness - no complex infra, no crypto team required.
Just fair, secure gameplay 🎮

After the bus factor, the boat favor 🙈 Ship it, quick!

PSA: I'm not a CryptoGopher anymore, I'm a Web3 Weaver.

I don't know how I did to live so long and deploy so many docker-based setup with @cloudflare.social in front without knowing about cloudflared tunnels. These are amazing, no more exposed port or firewalling issues, just straight from dev to production.

NFT Rarity Isn’t Magic, it’s Math and signature. If your NFT's rarity traits aren’t backed by verifiable randomness, then your rarity isn’t real.

Randamu brings verifiable randomness on-chain, making rarity truly trustworthy.

From fair games to NFT drops, randomness shapes outcomes.
The problem? It can be gamed.

Randamu fixes that 🎲
Using threshold cryptography, we generate randomness that can’t be predicted or manipulated and can be publicly verified on-chain.

Couldn't agree more. I have also met many other people at RWC that were similarly disappointed to learn that on the last day.

A slide about the Flush+Reload attack on Square and Multiply algorithm used in some cryptographic scheme, with an overlay blue box containing the resolution allowed for timer in different browsers or ecosystems. The Apple M1 has a resolution of 42ns, a surprisingly specific number...

Some Apple engineers must be having a laugh seeing their joke exposed 😂
#realworldcrypto

Super interesting number from the Let's Encrypt talk at #realworldcrypto : they need HSMs doing PQ sigs at a rate of at least 10,000 signatures per second to consider doing PQ at their scale.

Otherwise, it's confusing for the audience and gives them the impression they're missing out on the entire thing and that you're unsure or unprepared, probably not what you want as a speaker. 2/2

As both a speaker in large venues and an attendee, here's my 2c of advice for speakers: if you're presenting at something larger than a little meet-up, please try to remove the slides you won't be using from your presentation rather than jumping around 😅 1/2
