It seems CPU spot pricing has vanished because CPU demand is now high, making spot CPUs and reservations hard to obtain.
It seems that spot pricing has vanished because there’s no longer any lack of demand for CPUs – quite the opposite. I was surprised, but a lot of people chimed in; apparently, it’s now nearly impossible to get CPUs on spot instances without long-running connections with cloud providers. Also, reserving specific CPUs now needs to be done months in advance, and cloud providers will even turn down certain reservations because they don’t have enough CPUs or the right type of CPUs.

What is a korrent?
A korrent is a belief a person has stated in their own words: one sentence stating the claim, backed by a quote and a source, kept at korrents.com.
Under a name here, the quoted block is what they actually said. The korrent beneath it is the claim those words support, in korrents' wording — tap it to see the record, its source, and who else holds it.
Nobody here wrote their own korrents. They are compiled from public statements, and a person can change their mind, which is recorded too.

Liked Framework Design Guidelines: Conventions, Idioms, and Patterns for Reusable .NET Libraries
An eye-opening view on considerations going into building a widely used public API or reusable library. While the book focuses on the .NET framework, many of the conventions apply to maintainable and reusable components, in general. This book had an outsized impact on me as I read it when I was a mid-level .NET developer.

Liked Site Reliability Engineering: How Google Runs Production Systems
a good overview of SRE at Google. For those who worked at places with oncall, much of the first part of the book will likely be very familiar. Keep in mind that your mileage might vary: what works at Google scale, might not be the ideal fit for your use case.

Mixed on Javascript: The Good Parts
Before this book I used to think that Javascript is "bad" or a "hacky" language. This book changed my perspective, understanding some tradeoffs and some remarkable strengths of this weakly typed language that is starting to take over the world. Note that this book is now dated

Loved C# in Depth
C# is the language I probably understood down to the nitty-gritty details. Just when I thought myself of being an expert - knowing all that is to know on memory allocation, garbage collection, LINQ - I read this book. It made me realize how many things I did not know.

Loved Working Effectively with Legacy Code
Legacy code has no test and is not written to be testable. Touching it this sphaghetti code somewhere breaks the system. And to refactor safely, we'd need to have tests first... but where to start? This book gives practical suggestions

- I cannot recall any other time in the tech industry when the COMPLETE industry (from small to large companies; nonprofits to VC-funded; private sector to government and academia) is trying to figure out how to change the dev tools and processes we use. all AT THE SAME TIME!! 17 Oct 2026
- OK I want to give a shoutout to @Uptime_Labs - mentioned by @samnewman on the podcast. They do incident response training via simulations, so eng teams are better prepared when an outage happens. SO COOL! London-based (Zero affiliation: just love to see useful tools!) 17 Oct 2026
- A very very interesting and recent book by Dr Cat Hicks (@grimalkina): Pyschology of Software Teams She makes a good case on how most companies/teams don’t understand how devs operate and think of devs as “brains in jars.” And now we have AI suddenly enter the room… 17 Oct 2026

- At Big Tech annual events like AWS Re:Invent, Microsoft BUILD, GitHub Universe etc these co’s sell sponsor booths for PARTNERS in their ecosystem. Cancelling a sponsor booth last minute is unheard of: and yes, it suggests AWS is shit scared of Cloudflare, as a COMPETITOR. 17 Oct 2026
- Managed to meet another dev, whose first-ever fulltime job was also at a company called SenseNet, also building bespoke websites, except it was not this SenseNet, but another SenseNet This was the company I worked at as my first job How random...! (It's @SeanTAllen) 16 Oct 2026
- Cindy is one of the best distributed systems engineers I know, and resistant to any and all hype (also a great writer!) From her: "Claude (when given proper instructions, constraints, and context) now writes better code than me, almost always." 16 Oct 2026
- From a dev at a startup, talking about AI usage: "At my last startup, there was one dev. He used vim and could ship features to production faster than anyone else who was using AI. He did it at a higher quality, and this is what he continues to do. The best dev I ever met." 16 Oct 2026
- Going thru all responses. Such wild variance!! General trends: - PRs per eng is up - Spend is anywwhere from $100/dev/month to ~$5,000. A few outliers in Big Tech at $20K+ - Very very very few teams ask about the ROI on the spend!! Or know how to measure. More want to tho 16 Oct 2026
- I keep being surprised by devs who tell themselves that anyone who is convinced that LLMs are permanently part of how we build software suffers "AI psychosis." How do they reconcile that most tech professionals building production software all say the same + do the same? 16 Oct 2026
- Crazy how Anthropic started to hide the full names of engineers on its engineering blogs... never seen this happen in tech before. After the OpenAI espionage story I have empathy why they do it, but strange to see none the less Clearly shows eng at an AI lab is high stakes? 15 Oct 2026
- 1. A student from Waterloo emailed me asking for advice 2. Replied 3. Got an AI-generated reply, very clearly templated 4. Looked back: the original email was probably AI-written 5. This is how you wreck cold email for everyone else, even from univesity domains Dead internet 15 Oct 2026
- Wrote this in July 2025. It's now starting to happen, everywhere: build systems, CI, source control, code review: all under stress. Google was right, and you read it a year early in @Pragmatic_Eng at 15 Oct 2026
- Just thinking back how, in the late 2010s I was pulled aside by my skip level, who told me I was doing too many talks at conferences (representing the company - I did ~4 in a year) and he strongly suggests I cut back on it. And reflecting how today, most companies would WANT this I struggled to understand the reasoning at first, but turns out that more senior folks complained to this person how I probably wasn't doing my work (which I was) and the skip level just did not want conflict 15 Oct 2026
- I have not been aware of SO MANY big launches coming up last week of Oct / first week of Nov. AI is making everyone (small teams or big) build much faster… but companies know the importance of getting attention from existing and new customers on launch, and so launches are timed to try and maximize this in this “last major launch window of the year” (before BFCM and holiday season starts) 15 Oct 2026
- What do developer tools look like inside Uber, today? They are very different from what you would see at most places. We get a rare tour with one of Uber's longest-tenured engineers, Uday Kiran Medisetty (@udaykiran) - who was at Uber already when I joined in 2016!

- I don't think most people realize how complex and complicated agentic AI systems inside mid-sized and above companies are: by necessity, because there is SO MUCH context, but only so little AI contex windows. Case study on Uber's 19 internal, custom, AI-related systems coming later today in @Pragmatic_Eng So many of those "AI-related systems" are "systems pre-AI" that turned out to become extremely useful with AI. Like their PRD+ERD system that conveniently documents connections between the ~5,000ish internal systems inside the company! 14 Oct 2026
- This is one reason OpenAI hires whoever they want to hire (and why they can hire away from even Meta, Google, or any other Big Tech or AI startup, save for Ant) Compensation is well above what investment banking has been paying in London. 14 Oct 2026
- That cyberattack on the Netherlands’ largest retailer (Albert Heijn) means practically no fresh produce (fruits or vegetables) in their stores. Which is the first area you see when you walk in. Not good enough IT security having real-world consequences unfortunately 14 Oct 2026
- What is the PR output of your eng team, “before” and “after” adopting AI tools? And how much is your AI spend, per engineer, per month? Been collecting details+anonymising them: share details with me and I’ll share what other companies are seeing. It’s a very, very hot topic DM me 14 Oct 2026
- Imagine working at OpenAI as an engineer, making $1M+ per year in compensation, and then deciding that you'd throw away your career just like that by planting hidden recording devices in the office. Also, congrats on making the co be more suspicious of every + all employees now 13 Oct 2026

You can also watch it on YouTube, here: www.youtube.com/watch?v=Ru99... It's a summary of what I observed change in ~12 months. 6 Oct 2026
- Baffling how bad startup tech blogs are getting: more of them are AI nonsense. I know because every now and then a marketer emails me, hoping to get coverage. More of then not it's overly verbose, impossible to follow... AI slop. Feels like no one wants to put in the work 6 Oct 2026
- The cost of introducing and paying off tech debt has changed very, very much and I don't even know most of us have the time and space to think about what it means Tech debt has been so central to the software craft for decades, and now... how much does it matter? 4 Oct 2026

Only now realizing who the author is: Boris Cherny, widely known as the creator of Claude Code. Was a great writer + educator before :) 25 Sept 2026
- "Application development did not change much for 20 years, but now, a new wave is crashing in. Most computers in the future must be put to work at least in part w/o programmers. Not surprisingly, programmers will instinctively resist methods described in this book." - 1982, James Martin (cont'd) 25 Sept 2026
