@HiSaeloun Happy birthday! 🥳🎉

🎉 Saeloun turns 7 today What started as a small team has grown into a company deeply rooted in the Ruby and Rails community. We’re grateful for every project, every contribution, and every connection. Thank you for being part of the journey ❤️ #Saeloun #RubyOnRails #RubyCommunity

Ruby people, it's time to update your version of rack! github.com/rack/rack/blob… github.com/rack/rack/blob… github.com/rack/rack/blob… Risks are denial of service attacks and information disclosure attacks.

@skyhancloud @vedadsose @Railway Why cache anything?

@vedadsose @Railway Why cache API responses?

After a month of weekly outages, @Railway has now managed to serve cached API responses across users exposing personal data between accounts. This isn't a minor hiccup. We're moving on.

@johnpatricklowr We're so lucky to have you and @EllenMcLain in the DOTA2 community 😀! I hope you're enjoying Birmingham!

What a great time! Fresh meat! Fresh meat!

@SteffenFrolund @dhh Godt valg af platform, Billetto er skrevet i Ruby og bruger Ruby on Rails! :)

Billetsalget går fremragende. Der er allerede solgt halvdelen af pladsere på 1,5 døgn. Skynd dig at sikre din plads til når @dhh og jeg taler om Europas teknologiske retning, AI og digital suverænitet ✅

@mitchellh HCL is coming to Vercel

Excited to share that I've joined Vercel's Board of Directors. Vercel is made up of builders and tastemakers that continually ship things that deeply impact how developers work: Next.js, AI SDK, v0, etc. I can't think of a more exciting place to be. Let's fucking ship. ▲ My relationship with Vercel goes back to the earliest days. HashiCorp was an early adopter of NextJS and Vercel (~10 years ago!) and it remains my default tech stack and deployment platform to this day. Ghostty's website is all on Vercel, too! Beyond that, I've been continually impressed with the teams relentless focus on shipping meaningful software. And importantly, software that has incredible taste. Now we are in the age of agentic software development. Vercel is building agentic infrastructure that I think every app and agent will need (I certainly need it!) and I can't think of a more exciting place to be. Huge thanks to @rauchg , Jeanne, Marten, @cramforce, @tomocchino and the entire Vercel team for the warm welcome. Time to work.

@gindi4711 @opinali @chhopsky @elgato You have linked to the IoT release of Win10, a special OS for embedded devices. Windows 10 support is dead for consumers, unless you're enterprise or pay for extended support, more vendors will likely drop support soon, please don't run unsupported software.

@opinali @chhopsky @elgato Windows 10 is still supported until 2032: learn.microsoft.com/en-us/lifecycl… Only the regular Home/Pro versions have been discontinued Also not receiving security updates for the OS is not that relevant if it is the only PC in your network with owner as the only user behind a NAT

this is, unfortunately, the end of @elgato for me windows 10 is considered "must-support" for the game industry on account of its prevalence and while their target market is a subset of ours, i'd be amazed if their telemetry shows W10 use so low as to be an acceptable loss

@JuanMa698803 @JFest @Gr1zZtv How many people are gaming on embedded devices or enterprise installations of Windows?

@JFest @Gr1zZtv Except that just not true bro learn.microsoft.com/en-us/windows/…

@jakobkochkok Sidst vi lavede en bestilling og måtte aflyse, var fordi min hund var blevet meget syg (og måtte aflives efterfølgende), deres bookingsystem tilladte ikke aflysninger, så jeg måtte sende dem en mail. Man kunne i øvrigt ikke sende dem en mail direkte, da de udsendte fra no-reply@

På en fuldt booket aften, vælger 20% af vores reservationer at blive væk uden at give os besked. Hvorfor vil man byde andre mennesker sådan en opførsel?Hvor er respekten henne? En restaurant er drevet af mennesker som brænder for deres fag, knokler og fortjener bedre.

@s3rinx @NarutoNolimits Noah Wyle is an incredible actor.

@NarutoNolimits much better version of the scene... Pirates of Silicon Valley (1999)

When Steve Jobs decides Microsoft crossed the one unforgivable line

@PLT_cheater @camerasearch @signulll I found it here: ycarena.com/games/partners…

@camerasearch @signulll url?

how come no one told me investing is this easy?!!?

@lekterable @rameerez Can you tell me where in the AWS interface that I enable the spending limit?

@rameerez aight man, good luck on your totally realistic mission of fighting all the existing cloud providers, let me know once you get them! (I guess that’s easier than setting a spending limit)

Please do not run your projects on Vercel Setting up your own server (VPS) has never been easier. Even a single $100/mo VPS can sustain unreal amounts of traffic. You need to try it to understand it I've never had a surprise bill like this $50k for a server bill is BONKERS

@Broecher @KarinaMimoun De være i forskellige tidszoner. Kronprinsessen bruger måske norsk software, så deraf norske headings i hendes del af e-mailen, det kender du nok fra dit eget e-mail program når du trykker "svar" så kommer e-mail tråden som en del af e-mailen.

@KarinaMimoun Hvordan kan Epsteins spørgsmål være fra 16:37, mens svaret er fra 16:04? Og hvorfor er Headings pludselig på dansk/norsk? Der er vist mange, der synes det er sjovt at skabe lidt røre i andedammen.

Her troede jeg, at en kronprinsesse rejste på første klasse, men nej. Det er da et interessant indblik i en kronprinsesses liv.

@HenAnd2025 @UKnudsen Det er da ellers godt for vores vækst at få en innovativ art ind.

@UKnudsen Sika hjorten skal udryddes for det er en innovativ art, siger EU. Hvornår har vi hørt om hjorte der angriber mennesker og dyr? Men ulven den er beskyttet 😂

Vi skal slet ikke have ulve i Danmark. I 2024 blev registreret 76 ulveangreb. Det er i 2025 eksploderet til 231 ulveangreb på husdyr. Folk er utrygge og bekymrede. Problemet vil stige igen i år da nye kuld hvalpe fødes! Jagten skal sættes ind nu!

@nateberkopec I've started to move secrets to 1Password, and using the cli tooling from it. Does fnox read from a specific 1Password entry?

I'm moving to fnox for secrets management. I'm growing concerned about agents rogue-reading secrets out of files, so I'm using fnox to keep secrets inside 1Password and requiring TouchID to unlock. Great integration with mise ofc, which I already use.

@wrocloverb Happy new year! Will there be a third batch?

@wrocloverb Will there be a third batch, or are you sold out for 2026? 💚

The second batch of tickets is almost gone - we can't wait to see you all at #wrocloverb! 🤩 If you'd like to join us as a speaker, our CFP is still open and we're waiting to hear your ideas! Inspire your fellow developers, submit your talk here ➡️ papercall.io/wrocloverb2026

@LucasRolff @cooperx86 @marckohlbrugge I'm surprised about that, I find SES e-mails in spam all the time from companies, and it is messages that passes DMARC.

@cooperx86 @marckohlbrugge I went from postmark to SES as well, delivery seems similar, but faster and significantly cheaper as well 😌

I switched from Postmark to Amazon SES for cost and deliverability reasons, but missed the nice UI that Postmark provided. So I built my own 😁 It shows all events (email sends, deliveries, clicks, bounces, etc) in one timeline. Should I open source it?

@HiSaeloun Not yet by the looks of it.

Ruby 4.0 is here! New ZJIT compiler, Ruby::Box namespaces, redesigned Ractor API, and Set is now a core class. Check out what's new #Ruby #Ruby4 #RubyLang #Programming #WebDev #OpenSource blog.saeloun.com/2025/12/24/wha…

@fractaledmind Sounds interesting, but the link seems to be private?

The prompt: Can you "see" webpages if I give you links? Here are three of my favorite landing pages that use the TUI aesthetic: * openstatus.dev * turbopuffer.com * planetscale.com In case you can't hear are screenshots attached. I want you to redesign the HTML I've attached to get something that both feels unique and familiar with these. The result: gemini.google.com/app/f1ee065a28…
