We got an interesting use case from a customer - they need to verify  that documents in RavenDB have not been modified by any external party, including users with administrator credentials for the database. This is known as the Rogue Root problem, where you have to protect yourself from potentially malicious root users. That is not  an easy problem - in theory, you can safeguard yourself using various means , for example the whole premi....
What's a good way to enable or disable code paths without redeploying the software? How can you use feature flags to toggle functionality for specific users of your application? Christopher Trudeau is back on the show this week, bringing another batch of PyCoder's Weekly articles and projects.
Trying smee - christophvoigt.com - 8 months ago - eng
I recently learned about smee, which is a tool to forward webhooks (or any other kind of HTTP Post request) to a locally running service. This can come in particularly handy while developing a service locally, which isn’t exposed on your machine. The idea is simple: You create a channel on smee.io . This gives you a public endpoint that can receive HTTP POST requests. Smee.io emits incoming requests as Server-Sent Events (SSE) . A loc....
So much of what we develop these days ends up using HTTP. Usually when developing an HTTP service it’s quite easy to add logging to aid debugging. But when developing a client, especially one that uses a library which does the actual HTTP calls, it can be harder to insert logging in all the right places.
Introduction Yelp heavily relies on Amazon S3 (Simple Storage Service) to store a wide variety of data, from images, logs, database backups, and more. Since data is stored on the cloud, we need to carefully manage how this data is accessed, secured, and eventually deleted—both to control costs and uphold high standards of security and compliance. One of the core challenges in managing S3 buckets is gaining visibility into who is accessing y..

I recently got frustrated with Codex’s command permissions. They don’t let you configure which commands should always be allowed or denied. There’s an issue about it, but it’s been open for almost 4 months as of writing this. Their sandboxing is less convenient than tools like Claude Code, since it’s more of an all or nothing approach. So I decided to build my own solution. The Problem To make LLM CLI agents useful, you need to let th..

Wanna scratch your problem solving itch? Join the code golf competition with other lainons! The rules are simple: the first post with the text "Roll!" (or anything similar) in the thread decides which problem we will be solving. The post number will be inserted into this simple script as a seed: https://www.ideone.com/1vHLbP First output is the page number (1-79), second output is problem index (0-50) (within the page), problems are tak....
AI agents have officially fully infiltrated my development workflow. While it’s convenient to delegate tasks to them so I can focus on other things, it’s worth remembering that, at their core, these systems are still just highly advanced predictive text engines. And one thing they excel at — beyond cranking out boilerplate code — is conjuring up dialogue and imitating characters with ease. So next time you’re tempted to have your agent wr..

You are in the process of putting together your application. While designing your authorization solution, you realize you will need to send emails to potential clients.Using a third-party service (like SendGrid or Mailgun) to cover your needs for now looks pretty attractive. After all, you don’t have any users yet, they offer free tiers, and […] The post Postfix on Kubernetes: A Step-by-Step Email Guide appeared first on RisingStack En..

Not long ago, I introduced acp.el , an Emacs lisp implementation of ACP ( Agent Client Protocol ), the agent protocol developed between Zed and Google folks . While I've been happily accessing LLMs from my beloved text editor via chatgpt-shell (a multi-model package I built), I've been fairly slow on the AI agents uptake. Probably a severe case of old-man-shouts-at-cloud sorta thing, but hey I want well-integrated tools in my text....

IO Activity Tagging - rocksdb.org - 8 months ago - eng
Context RocksDB performs a variety of IO operations—user reads, background compactions, flushes, database opens, and verification tasks. Treating all these operations the same makes it difficult for file system implementers to optimize performance, prioritize latency-sensitive IOs, and diagnose bottlenecks. To solve that, RocksDB internally tags every IO operation with its activity type using the IOActivity enum. This automatic tagging pro....

Context / Problem Modern RocksDB deployments often run in environments with strict memory constraints—cloud VMs, containers, or hosts with hundreds of DB instances. Unpredictable memory usage can lead to out-of-memory (OOM) errors, degraded performance, or even service outages. Historically, while the block cache was the main source of memory usage, other components—such as memtables, table readers, file metadata, and temporary buffers—cou....
hello lainons, i started studying IT this year and while most things are still new to me, i do have some small experience with JavaScript, MySQL, and Python already. i've also practiced a bit of Java in the past (free online courses to learn the basics) and preferred the C-like syntax. unfortunately my uni only offers Python and C# classes and wants us to only use those languages for projects... i already know i want to choose the cs..
Ur-Fascism - nicolaiarocci.com - 8 months ago - eng
Prompted by an old post by  Bob Schwartz  (2017), I revisited and reread  Ur-Fascism , the essay Umberto Eco wrote in 1995 for the  New York Review of Books . What are the features of Fascism? We need to know, so we can recognize them and point them out as they emerge, as they always tend to do, time and time again, as our societies struggle to evolve. Sounds like heavy reading material, but it isn’t. I mean, look at the incipit:
This post is part of the T4p Series. So in this post, we are going to combine two indicators: RSI and Moving Averages to come up with a strategy. But first, let’s talk about what we mean by a “strategy.” A trading strategy is simply a set of rules that tells you when to buy and when to sell. It’s different from just using individual indicators because it combines multiple signals into a complete system. Whether you use a single indicator or....
The Old Way vs. The Reality of Your Customers For years, the gold standard for benchmarking web performance, particularly for Google’s Core Web Vitals (CWV), has been a mobile device baseline—specifically, a throttled connection and CPU designed to simulate a Moto G4. This approach was established with good intentions: to ensure websites are accessible to […]
This document details how preconnect improves web performance, especially for Bazaarvoice's third-party content, by accelerating connection setups and reducing LCP. Crucially, internal testing confirmed preconnect operations are not counted as API calls, validating a "no count, low cost" model—a key insight for our developer blog.
The DEBI (Data Engineering and Business Intelligence) team recently attended the DataEngBytes 2025 conference, where the hot topic for the year was, unsurprisingly, AI agents. My favorite talk, by Geoffrey Huntley, presented a powerful and surprisingly simple idea: It’s not that hard to build an agent; it’s a few hundred lines of mainly boilerplate code running in a loop with LLM tokens. That’s all it is! Kogan DEBI team at the DataEng....
