@dvarrui @_st0012 They are attaching to the process from another process via a socket, thus remotely. Remote doesn't always mean another machine, it can also mean another process.

Latest prototype: `binding.irb(agent: true)` to let agents interact with your running Ruby program through a local socket. No skill or MCP server required. Basic instructions prompted upon first socket connection.

@grok @HannibalBonapar @pali_ta_idia @ArkeolojiveTurk Basically, the treaty was signed by Turkey to promise the continuation of 1960 Republic with its integrity, constitution and people intact. Declaring a separate state in the north of the island goes fundamentally against the treaty of guarantees, so you can't invoke that anymore.

Arkeoloji ve TÜRK Tarihi@ArkeolojiveTurk·
Rum Cypriots have committed "war crimes, crimes against humanity," and "crimes of aggression," crimes determined by International Criminal Law and investigated by the International Criminal Court. The fact that Rum Cypriots have not been tried for genocide is an obstacle to world peace.

Elk 🇬🇷🇨🇾@Schopenhaueress

Cyprus has been under Turkish occupation since 1974. Any claim that Turkey acted as a “guarantor” of the island is nullified by the very act of invasion and ongoing occupation (Treaty of Guarantee, Article IV). A state that occupies territory, seeks the dissolution of the Republic of Cyprus, and refuses to recognize that internationally recognized state to this day cannot credibly claim the status of “guarantor.” Turkey is not a guarantor of Cyprus; it is the occupying power.

I can't make sense of this: UK makes a statement at ~23:00 (Cyprus time) about UK joining the war effort in a defensive capacity & the drone hit in Akrotiri happens at 00:03. Lebanon is 250km away, and Shahed-136 top speed is 185km/h. Make the math work!

@palkan_tula @nateberkopec Rspec isn’t not only deprecated, it is forbidden. Projects using it in the past aren’t asked to rewrite the tests, but new projects can’t use. And with AI, there is a possibility we will rewrite

@nganpham @keystonelemur @nateberkopec Another great example of LLMs reducing the coefficient of static friction and making it possible to create projects that you always wanted to ship but never had the time to. Love it!

If you have slow tests in your Rails app, the problem is usually in one of three places: 1. Factories 2. Factories 3. Factories

The confidence with which LLMs can explain a concept to you but be wrong needs its own concept. I propose "llmsplaining"

I recently built psych-pure, a YAML 1.2 parser and emitter written in Ruby. At a high-level, I wanted: - a fully conforming parser, runnable on any Ruby - the ability to preserve comments through load/dump kddnewton.com/2025/12/25/psy…

@lucianghinda Completely agreed. It is also what a lot of right-wing US politicians want the US to be with a smaller federal government and increased state rights. If the EU model is such a bad thing, why would they want that? 🤔

This will only create complex decision-making systems and bureaucracy to make sure all are on the same page (the lowest common denominator) and none is left outside or else they vetoa it. => hard, slow, complex rules kept together by huge amount of people

I don't understand why so many people in the replies to this post don't understand how complex EU is: - Countries don't want federalization - They also want their veto rights for almost all decisions, Meanwhile we want the EU to act fast and simplified
@levelsio@levelsio

Millions of views on me not being able to get an EU GPU If this was about Google @OfficialLoganK would be in the replies promising a fix If it was about xAI @elonmusk would see it himself probably Meanwhile the only thing the @EU_Commission has posted is to be cautious of fake news! The EU doesn't even monitor their mentions on here and they definitely don't reply nor does the EU's president @vonderleyen Which is funny because the biggest companies in AI here do, they reply on here to hear feedback and improve their trillion dollar companies It's just crazy to me how disconnected the EU is from European citizens now: there's no dialogue, it's just a one way street of imposing rules and regulation and burning billions of € of European people's money with little checks or balances It's very frustrating but Europe is our homeland so we should keep fighting for it

I am happy to see that RubyGems and Bundler have moved to the Ruby Core team. Being one of the originating authors of RubyGems (and host of RubyGems for 4 years!) this was always about making Ruby easier to use and share code as a community. I still write Ruby almost every day and I want our community to thrive. Thank you @rubycentralorg and @yukihiro_matz!
