Yes! This!!! Observability is the sense mechanism that creates a feedback loop. No observability? No loop. You're just injecting chaos into the system and walking away. If you observe, and learn, and iterate based on what you learned... That's how you build great software 💜

If you’re writing opinions on whether to do code reviews, write tests, or any part of production lifecycles these days, you should have to disclose if you personally are part of a PagerDuty rotation

@ColoneMark Upstate NY style! Stay warm cousin.

@virtualandy We now have 10.5 inches and I have shoveled 6 times. It is pretty insane for here.

6 inches in Belmont.

My son's 12U baseball team is headed to Arizona in March and 10ish tournaments this summer in CO. They're doing a Player Assist Fundraiser to raise money. I would be thrilled if you could support him! event.operationplayerassist.com/t/8UZ1/

It's the time of year for reflection. I jotted down my thoughts on why books are still essential in the age of instant information. Link below. Oh, and there's a 40% off coupon on all books from pragprog.com

@HamelHusain ELI5 - what does that look like? I guess prompt + output per cell?

The best eval tool by a wide margin is reading your traces into a Jupyter notebook

I'm trying something new with my blog, making it interactive first article is about something I care deeply about: logs logging sucks so much loggingsucks.com

😍Really loved this framing from @eugeneyan on how to build product evals (for ai applications) in three simple steps! We built LangSmith to make it easier to build evals - so I recorded a quick video showing how you can do each of these three steps: youtu.be/mz7mAo4zIC8

@lavrobs @nateberkopec percona.com/software/datab… is pretty good too

@nateberkopec What Postgres database observability tool do you recommend? It's almost a blind spot for us, as the PAAS addon shows only IO and CPU stats on 2 graphs

Most of my job is actually just improving observability. About 80% of perf problems are so drop dead obvious as to HOW to fix, but engineers actually have no idea that they’re even happening.

🤖Agent Framework vs Runtime vs Harness A term I've heard recently is agent "harness". We're building DeepAgents to be that I wrote a blog on my interpretation of that term and how it differs from "framework" (LangChain) and "runtime" (LangGraph) blog.langchain.com/agent-framewor…

Waiver wire deadlines should always be Wednesday: -Tuesday is a day of research and rest. -Waiver wire Wednesday. The alliteration is perfect. It’s right there. -Also get new injury info on Wednesday. Just a complete letdown by society to have Tuesday as the usual day.

An easy way to keep your VPS secure as many people in the replies said is @Tailscale Tailscale is very hard to explain and I barely understand it but it creates a private network with just you (your laptop for ex) and your servers in the cloud Nobody else can access that private network Installing it is easy, smth like: curl -fsSL tailscale.com/install.sh | sh sudo tailscale up But check the commands yourself always, then you click a link, login to Tailscale, add your server to your network, then after you type: tailscale ip -4 And that gives your server a new IP via Tailscale, you SSH via that (I use @TermiusHQ) and then in your firewall (on Hetzner or Digital Ocean you can change the firewall in the dashboard easily) you set to only accept SSH connections (usually port 23) from the Tailscale network: 100.64.0.0/10 Now nobody can SSH into your server ever, only you inside your Tailscale network! I learnt this with ChatGPT btw after seeing @DanielLockyer install it on my main server, but today I installed it on all my Hetzner VPS's for extra security!

Just because it’s bleeding edge doesn’t mean it’s the right move. The @./deploy team talks about knowing when to walk away. Full episode here! youtu.be/ZAL1kS1666I?fe… #DeployPodcast #TechStrategy #SoftwareDevelopment #Focused

feel free to take a look at what I have been up to in my spare time at lnkd.in/g8wqKwB7 and take a peek at my resume at lnkd.in/gMffDDee Looking forward to what this next chapter holds!

Microservices for legacy apps: helpful pattern or unnecessary complexity? On our latest ./deploy episode, @austinbv, Micah Adams, and Shahed Syed weigh in. Spoiler: they’re not fans of the hype! They break it down even more in the full episode! youtu.be/oXiFA2zbAVI?fe…
