Merging a PR is easy.
Knowing it won’t break production? Not so much. 😅

Our latest article shows how Bitnami Secure Images gives DevOps teams full visibility, from CVEs to SBOM diffs, before hitting merge.

CTO asked to reduce S3 costs. We were spending $4,200 monthly on storage.

Implemented lifecycle policies:
- Move to Glacier after 90 days
- Delete after 2 years

Cost dropped to $980 per month. Saved $3,220 monthly. DevOps team got praised in all-hands meeting.

Three months later, customer needed a file from 120 days ago. Normal retrieval: 3-5 hours. Expedited: $150 for one file.

Turns out those "old files" weren't old. They were:
- Compliance records customers accessed quarterly
- Historical reports used for annual comparisons

Spent $2,400 in Glacier retrieval fees over 6 months. Wiped out all savings.

Lesson: Know why data exists before deciding how long to keep it. Cheap storage that's inaccessible isn't cheap.

Using co-pilot is like giving a coffee pot to a six-year-old and say, ‘take this into the dining room and pour coffee for the family,’
Can they do it? Possibly. Could they fail? Definitely. Most likely, if they do fail, they aren’t going to tell you. https://t.co/fmVnUkxUva

Next time you’re tempted to include “A utility function that determines if its argument can be used like an array” in your project’s dependencies…better think about it long and hard 🤨 https://t.co/TFlNZtB0kI

gpt-oss is out!

we made an open model that performs at the level of o4-mini and runs on a high-end laptop (WTF!!)

(and a smaller one that runs on a phone).

super proud of the team; big triumph of technology.

If you're packaging Java apps into Docker images, you'll want to check out Bitnami Secure Image: Java-Min.

I wrote a post explaining why it's a great choice: it's secure by default, trimmed down for efficiency, and perfect for production use.
