You forgot to mention how they - deported homeless - expelled students (from unsanitary housing that the police is now complaining about) - multiplied the price of public transport by ~2.5 - rely on free work of volunteers (feels like exploitation) - …

Oui, et aussi à lire, à écrire, à compter, à être des citoyens … C’est ça vivre en société. C’est plus qu’une somme d’individualités qui se moque les uns des autres

Étape 1: refuser l’union de la gauche avec l’argument « Pas de fachos chez moi » Étape 2: laisse gagner le RN et avoir un gouvernement de fachos Étape 3: ne surtout pas faire d’auto critique

Ils sont mariés. Ce n’est pas un contract entre eux ? Il a une micro entreprise. Ce n’est pas un contract entre lui et l’état ? Quid de leur compte sur les réseaux sociaux, de leur abonnement EDF et telecom pour poster leur âneries ? Ça contracte quand même pas mal on dirait.

France 62 is plain and simple wrong. French citizen can retire at 62 iff they worked for 43 years. That means starting at 19 and having no unemployment period. If you study after 19, and start working at 23, you won't be able to retire at 62.

⚠️⚠️⚠️ EthPOW Warning ⚠️⚠️⚠️ EthPOW might have changed their chainId, making native transaction non replayable (this is good) ... ... but many EIP-712 contracts actually cache the domain separator. 1/3

Yesterday, the @OpenZeppelin contracts released version 5.3 of the library, with many new features for you to discover. A few hours later my wife released baby Roxane, 3k940. Everybody is doing well! I am now taking few weeks off to take care of my family.

C’est cool. Les partis de gauches tirent les uns sur les autres depuis des semaines … sous prétexte que c’est un scrutin de liste donc osef. Et la du coup il y à tout juste 3 semaine pour se rassembler, ce qui semble impossible au regard des derniers jours … bien joué !

Nice try: - First line is not actually a contract, its a proxy that redirect all call. It does NOT contain the token logic - Second line is WETH, which is compiled without optimisation so is notoriously big Intellectual honesty: 0/100 🤡

As a solidity developer you should always ask yourself. How big does the ID needs to be? do I expect billions of billions of users? How much value are user going to send? Do I expect hundreds of thousands of ETH? This struct could easily fit in one slot!

Life might not be the blockchain with the highest throuput, but producing this block is my greatest pride. Both the mother and the baby are doing great. I'll be taking some time off to take care of my family.

This was probably the best swag I ever got at a crypto conference @ETHBerlin One thing that could surpass it would be a book of all final EIPs and ERCs. I’d use it literally every work-day. Can someone please do that for @EthCC ?
