In recent years, software development has made big strides. Tools like GitHub Copilot, ChatGPT, and other AI helpers have given developers the power to churn out code, tests, and documentation faster than ever. However, for solo founders and small startup teams, getting things written is only half the battle. Real challenges lie in getting it […]

Every tutorial you read shows a different way to import Statsmodels. One guide starts with import statsmodels.api as sm. Another uses from statsmodels.formula.api import ols. A third imports directly from submodules like from statsmodels.regression.linear_model import OLS. Which approach should you use?The confusion stems from a deliberate design choice. Statsmodels offers multiple import paths because different users need different things. Researchers writing academic papers want one workflow. Data scientists doing quick exploratory analysis want another. Understanding these three approaches will save you from blindly copying code that doesn’t match your actual needs.Statsmodel Beginner’s Learning PathUnderstanding the Three Import ApproachesApproach 1: statsmodels.api…
If you are in charge of managing a database server, from time to time you may need to run a query and inspect it carefully. While you can do that from the MySQL / MariaDB shell, but this tip will allow you to execute the MySQL/MariaDB Queries directly using the Linux command line AND save the output to a file for later inspection (this is particularly useful if the query return lots of records). Let us look at some simple examples of running MYSQL queries directly from the command line before we can move to a more advanced query. Setting…
As development environments evolve at breakneck speed, our approach to securing them remains stuck in the past. I’ve watched countless organizations implement robust Identity and Access Management (IAM) solutions, deploy Identity Governance and Administration (IGA) tools, and then breathe a collective sigh of relief, believing they’ve solved their access control challenges. But have they? An […]
A New Approach for Coding Agent Safety Coding agents like Claude Code, Gemini CLI, Codex, Kiro, and OpenCode are changing how developers work. But as these agents become more autonomous with capabilities like deleting repos, modifying files, and accessing secrets, developers face a real problem: how do you give agents enough access to be useful without adding unnecessary risk to your local…
Organizations today face a structural problem that is slowing down their move to cloud-native maturity. They’ve adopted modern DevOps tools, yes. They’re running Kubernetes. They’re using sophisticated observability platforms. But the people-and-process piece often remains stuck in the traditional enterprise IT paradigm. The rift is simple: developers are tasked with delivering features, and operational staff […]
It’s Monday. I’ve been home since Fri night, but with a busy weekend, I’m still recovering from the PASS Data Community Summit. There’s a nice wrap from the crew, which you can watch. You might spot yourself in there if you attended.This is a short post of some memories and photos from the event. As usual, I wish I had more. One sad thing was Chris Yates not coming due to other commitments, but I loved seeing him on a sign in the convention center. I sent him this shot.Every year I find myself either over-committed or under-committed. The latter…
Many SRE initiatives stall because organizations adopt the title without the principles. True SRE success requires leadership vision, cultural change, shared KPIs and continuous maturity measurement—not tools alone.
When you’re managing a Linux server, especially one with multiple users, you need visibility into what’s happening on your system, such as who’s logged in? What commands are they running? how much CPU time is being consumed? These aren’t just curiosity questions; they’re essential for security, troubleshooting, and resource management. psacct and acct are both open source utilities for monitoring users’ activities on the Linux system. These utilities run in the background and keep track of each user’s activity on your system as well as what resources are being consumed. I personally used these tools in our company, we have…
Coding agents like Claude Code, Gemini CLI, Codex, Kiro, and OpenCode are changing how developers work. But as these agents become more autonomous with capabilities like deleting repos, modifying files, and accessing secrets, developers face a real problem: how do you give agents enough access to be useful without adding unnecessary risk to your local environment? A More Effective Way to Run Local Coding Agents Safely. We’re working on an approach that lets you run coding agents in purpose-built, isolated local environments. Local sandboxes from Docker that wrap agents in containers that mirror your local workspace and enforce strict boundaries…
