What if your Kubernetes cluster simply refused to run unsigned images? I spent some time experimenting with enforcing image provenance in a small Kubernetes setup using MicroK8s. The idea was simple: Only container images with valid cryptographic signatures are allowed to run in the cluster. For this I used: GitLab CI/CD (build + signing pipeline) Cosign / Sigstore (image signing) Kyverno (admissi
In today’s world, learning skills like coding is more important than ever. But many students struggle to find the right guidance, support, and environment to grow. That’s where Master Coding Org (MCO) comes in. Master Coding Org (MCO) was created with a simple mission: Make learning coding accessible, collaborative, and practical for everyone.

r/startpages Is the Most Underrated Firefox Community You're Not Using If you care about browser customization, there's a subreddit you probably haven't found yet: r/startpages. With 35,000+ members, it's a community of people who genuinely care about what appears when they open a new browser tab.

Most teams I have worked with have one auth test in their suite. It looks like this: test('valid token verifies', () => { const token = signSync({ sub: 'user-1', aud: 'api://backend' }, secret); const result = verify(token, options); expect(result.valid).toBe(true); }); That test is fine. It is also a smoke test, not a regression suite. It catches the case where verification is completely b
The on-call alert at 02:14 said auth_5xx_rate spiked from 0.01 to 31.4. Not a deploy window. Not a traffic spike. Just thirty-one percent of authenticated requests failing for ~four minutes, then back to baseline. The cause was a JWKS rotation on the issuer side. New keys came in. Old keys went out. Caches in our service didn't refresh fast enough. Tokens signed with the new key were rejected beca
Midnight. Blank screen. One question: The problem nobody talks about What Good Deed Board actually does "She'd been putting off that errand for three days — her knees were bad and the traffic frightened her. The moment you offered your arm, she felt the world was still kind. She called her granddaughter that evening. Told her the story. Her granddaughter said - 'See gran, people are good.' She'd n
A sponsor’s perspective This blogpost is written on the heels of a few amazing weekends spent knee-deep in students in Toronto and Los Angeles at Hack Canada and LA Hacks, engaging almost 2000 students in person in total. Managing a sponsor track, I have some thoughts on good ways to present yourselves when angling your project towards a sponsor prize. For those not as familiar with how student ha
