At ElixirConf US 2025, Gonzalo Rodriguez explains how to build an exception tracker in Elixir - capturing runtime errors across BEAM processes and handling even silently rescued exceptions. https://t.co/dL95cHg4z0

[ElixirConf @ElixirConf]

🛡️ Learn to build secure, observable systems! Join Matt Ludwigs, @maennchen_, @Nezteb & @grzuy as they cover Elixir security, telemetry, exception tracking & more.

[Gonzalo @grzuy]

Tower has fully de-coupled exception capturing from reporting. Capture once, report to one or many destinations.

Meaning, you can, at any time, try out an alternative "Error Tracking service" as you continue to use the current one without disruption.

@IAmKale @alexseigler @codekaiju I think we had the exact same issue last year with webauthn-ruby https://t.co/8g6x1jc3BA Amazing 😀

[Gonzalo @grzuy]

@santib6_ Very nice!

I'd say by @cedarcode team, plus the invaluable contributions from @bdewater.

[Gonzalo @grzuy]

@jm3 Glad it helped. Thank you for the feedback @jm3.

@Tangui @dzhuvi ES256K appears to be updated to "requested assignment -47" in the last draft: https://t.co/a9I31T4gcR

[Gonzalo @grzuy]

@Tangui @dzhuvi Not sure that HSS-LMS assignment is final. In https://t.co/pKZozaPBA8 it says "TBD1 (Value between -256 and 255 to be assigned by IANA, with a preferrence for -46)"

Interesting ideas on upgrading dependencies in your ruby app by @grzuy. Prioritizing value vs risk when trying to upgrade a dependency!

Lots and lots of #rubyfriends after Day 1 of #rubyconf! Thanks to everyone for coming (and reply here because I can't tag everyone)!

[Gonzalo @grzuy]

@jleo3 Thanks @jleo3! Had a great time!

[Gonzalo @grzuy]

Hi #RubyConf, if you have any feedback about how I can make the Rack::Attack gem better, I'd love to here you. Ping me or say hi in the lobby 👋🙂

[Cedarcode @cedarcode]

Come join @grzuy and @brauliomlm at @bostonrb
tomorrow! Our team is talking about the #WebAuthn #Ruby gem and how to adopt it on production-ready applications. More details here: https://t.co/zAMQl8TKHi

[Cedarcode @cedarcode]

Build a #security culture: be safe by default, encourage learning about security, and security is everyone's responsibility. The best takeaways from @jackmccr 's talk about "Rails Security at Scale". It's cool to know how @Shopify approaches such a sensitive matter. #railsconf

Ruby Repository Moved to Git from Subversion https://t.co/p9OdV0c5A8

[The FIDO Alliance @FIDOAlliance]

#FIDO2 #WebAuthn update: @w3c moves the Web Authentication API to Proposed Recommendation status: https://t.co/EqFPoCXeBN

If you ever had to write an_array[1..-1] to get the "rest of an array" in ruby like me, I think you will appreciate new "endless range" syntax in ruby 2.6, i.e. an_array[1..]

[Ruby Programming Language @rubylangorg]

Ruby 2.6.0 Released https://t.co/f13Huyzx8N

[Gonzalo @grzuy]

Happy to chat about #WebAuthn in ruby or #WebAuthn in general with anyone interested or curious. Ping me. #RubyConf.

[Gonzalo @grzuy]

Happy to be in LA for this year's #RubyConf!

X509 Certificate verification affected. Latest patched ruby releases (e.g. 2.5.2) fix this.
