How can sysadmins help software developers work securely and make more secure applications? While at NDC in Toronto, Richard sat down with Tanya Janca of SheCodesPurple to discuss what admins can do to help address the security challenges software developers face. Tanya talks about securing development environment and pipelines - developers routinely work from high privilege accounts because their tools require it, and as a result, have become the targets of black hats to get access to accounts, keys, and other exploitable resources. There are plenty of tools available to help work through the issues, including the latest AI-powered tools. LLMs can also help generate more secure code in the first place, and Tanya has created a set of prompts you can use to create more secure software. The threat landscape is shifting with these tools, and we need to act quickly to resist the new attacks!

The 47-day certificate is coming! While at NDC in Toronto, Richard received an update from Todd Gardner about his show last year: certificate authorities are moving toward SSL certificates that last only 47 days! Todd talks about the first decrease in duration that has already passed - as of March 2026, the longest duration certificate you can buy from certificate authorities is 200 days. At the core of these changes is the problem that certificate revocation just isn't working properly, so a short certificate lifespan is the effective solution. Short certificate lifespans make automation to replace certificates essential - and that's where CertKit and other tools come in!

What can go wrong with machine learning? While at NDC in Toronto, Richard chatted with Megan Robertson about her experience with machine learning projects, often using retail datasets, and where they can go wrong. Megan talks about getting clear expectations and metrics for projects, so you know when you succeed, but then digs into the specifics of problems in machine learning, such as overfitting on test data. Your results are only as good as the data you put in, so a lot of focus goes into building good sets, carefully developing the model with those sets, and using techniques like cross-validation to ensure the model is behaving appropriately. There's a lot that can go wrong, but the results with an effective model can be very powerful - it is worth the effort!

How do you intelligently surface access to your database? While at NDC Toronto, Richard spoke with Jerry Nixon about Data API Builder, Microsoft's tool that enables data professionals using Microsoft databases, including SQL Server, Postgres, CosmosDB, and MySQL, to provide an API layer with security, schema extraction, and governance policies. You can expose the API as a REST interface, a GraphQL interface, and an MCP server! This is a powerful tool for providing controlled access to data while still allowing for ad-hoc access. The potential is huge - you need to check it out!

How can Microsoft Loop make your team more productive? Richard chats with Karinne Bessette about the role that Loop components can play in making meetings where the agenda is live, generating work items in Microsoft Planner, and keeping key information up to date. Karinne talks about how Loop components can be connected to any M365 document, including Outlook, Word, Excel, and OneNote, but only for members of the M365 tenant. Loop is a powerful tool for productivity within the organization!
