💡 Quick Linux Tip #1 Need to find which process is eating all your disk I/O right now? Use: $ iotop -o It shows only the processes actively reading or writing to disk, updated in real time. The -o flag filters out idle processes so you're not hunting through noise. One glance tells you exactly which service is hammering your disk before your storage team calls you first.

For two decades, S3 has been an object store, but today it's something broader. S3 Files lets you mount any bucket as a filesystem—no copies, no sync scripts, no choosing between file and object. @andywarfield tells the full story, including the "filerectories" that almost made the cut. allthingsdistributed.com/202…

Explain inode exhaustion. How can a disk show free space but still refuse to create new files?

You run EXPLAIN ANALYZE on a query. You see "Seq Scan" instead of "Index Scan" even though the index exists. What does that tell you?

Git Flow - Finally makes sense 🔁 main → production develop → working branch feature → build release → stabilize hotfix → fix production fast Most people memorize Git. Top engineers visualize it.

Stop guessing which queries are slowing your DB down. This dev walks through using pg_stat_statements to see which queries consume the most total CPU time — and how to tell the difference between a slow query and one that's just called too often. { author: Labeeb Ahmad } dev.to/labeeb-ahmad/finding-…

Here’s a cheat sheet with common uv commands for developers uv.pydevtools.com/

Postgres tip: Autovacuum includes a table ANALYZE but a manual vacuum does not. VACUUM removes dead rows. ANALYZE refreshes statistics for query plans. If you have to run a manual VACUUM, it generally makes sense run a VACUUM ANALYZE so you get both.

Lambda memory is directly tied to CPU allocation. Bumping from 128MB to 512MB often makes functions run 4x faster, and costs the same or less because you're paying for duration × memory. Always run Lambda Power Tuning before assuming your config is optimal.

CloudWatch Logs default retention: Never Expire. Every team forgets to set this. 6 months of Lambda, ECS, and VPC Flow Logs sitting forever, at full price. Set a retention policy per log group. 30-90 days covers 99% of debugging needs.
