This year for Valentine's Day, we're imagining what a love letter from your applications to the tools that keep them secure might look like.
Developers are using AI, and there’s no turning back. Here’s how you can minimize vulnerabilities and security risks associated with AI coding tools.
Dear Internet, I’ve never written to you on this special day before, so I thought I’d give you a surprise this time! After all, we’ve been through a lot together, since our first encounter over a dial-up connection in the early two thousands. I was late to the party, I know, but it’s not my fault to have been born in the early nineties! Some people say you are slowly dying.
On-premise and Offline map server can now mosaic different layers with color-toning to create seamless, beautiful maps.
This post challenges misconceptions about chaotic on-call and livesite practices, offering lessons from extensive experience. It introduces common red flags like call hell, hero worship, and the wild west, and provides solutions. These include customer-focused monitoring, monitoring pruning, 1-2-3 troubleshooting rule, follow-the-sun schedules, and repair item deadlines. As services mature, standardized incident response and efficient toil ..
The Hugo Switch - peekread.info - 2 years ago - eng
I've decided to shake things up a bit, and I'm switching my blog over from Nikola to Hugo . Page Bundles and Obsidian Page bundles offer great convenience for storing my blog posts in Obsidian. With Hugo, they group content along with associated resources like images and files. With this portability, I can store my posts within my note structure. While Nikola could provide similar capabilities to some extent, it's worth exploring alter....

How I switched my side project from using Amazon S3 for file hosting to using Tigris (which is built on Fly.io infrastructure). It was a good experience overall, but there were a few quirks.

Back in 2007, my third blog entry was about a parallel index building gotcha , a warning about building & rebuilding indexes in parallel. After completing the build, Oracle left the parallel degree in place for that index in data dictionary. Thus, after building a great new index over some weekend, many of your OLTP queries could have picked a parallel plan afterwards! Whenever creating/rebuilding any indexes, I had a habit of writing up..

I had the pleasure of giving the keynote presentation at NANOG90 - sharing some thoughts and lessons that we have learnt in the 10 years since we started the OpenConfig project. This was a really enjoyable presentation to put together and give. It balanced being able to look back at what we’ve learnt, and also think about some important lessons that I wanted to share with the networking community.

Translation of the buisness goals to the actual parameters of the statistical procedure is a non-trivial task. The degree of non-triviality increases if we should adjust several parameters at the same time. In this post, we consider a problem of simultaneous choice of the confidence level and the practical significance threshold. We discuss possible pitfalls and how to simplify the adjusting procedure to avoid them.
Recently I spent two weeks collaborating with Prefix.dev to further develop resolvo, their SAT-based dependency solver. The main goal was to fix a nasty bug, where the solver unexpectedly panicked upon hitting code that was supposed to be unreachable. “That will make for a good war story!”, I thought, so I kept notes of my debugging process to serve as a basis for this article. I was being overly pessimistic, though, thinking it would take ..
Anomaly detection for time series is like finding unusual events in a sequence of data over time. It helps identify outliers or deviations from the expected pattern, signaling potential issues or anomalies in the dataset. This is the theory, but how does it translate into practical implementation for real business needs?

Since at least the 1980s I've kept a (very intermittent) dream journal in various forms, including dedicated paper notebooks notes or drawings in sketchbooks fragments of entries in daily Org Mode diary pages individual iCloud Notes, one per dream a single, dedicated Org Mode file. Lately I thought it might be interesting to review these and possibly use them as ideas for artworks, and I've found last format to be most amenable to lat....
Welcome back to our thrilling adventure through the Bandit Challenge! In this blog post, we'll conquer Level 12, where we'll encounter a password stored in a file where all the letters have been rotated by 13 positions. Join me as we navigate through the file system, decipher the rotated letters, and successfully extract the password. Let's dive in!

For the past 829 days, I’ve been recording my calories - what I’ve eaten and what exercises I’ve done - in MyFitnessPal. I’ve also been recording my weight almost every Monday, Wednesday, and Friday.

Warning: This Diatribe was written in anger, but contains grains of truth Around a year ago, I decided to shutdown my self-hosted email service after running it for about ten years. My choice in doing such was simply cost related - for the scale of email I was processing, it was not viable to run my own servers to do as such, accounting for time in maintenance and ensuring deliverability. At the time, Skiff mail had been around for around..

We recently released a series of improvements to Snyk IaC, and in this blog post, we’re taking a technical dive into a particularly interesting feature — automatic source code locations for rule violations.
C++ STL strings bring 20,000+ lines of code to every compilation, yet remain slower than LibC and error-prone. StringZilla offers a faster, more intuitive alternative.
