Taming GCE Memory Tax: Disabling OS Login and OS Config on Small Instances // Tony Metzidis
Google Compute Engine’s e2-micro instances are a staple of the GCP Free Tier, offering 2 vCPUs and roughly 1 GB of RAM (969 MiB usable). They are ideal for lightweight bastions, cron runners, and small test beds. However, if you run memory-sensitive workloads—such as Go builds, package extractions, or continuous process forks—you may have experienced intermittent, baffling SSH connection timeouts and unresponsive terminals. The root cause is rarely your application alone. By default, GC...| Tony Metzidis
Installing CuBox-i firmware on Debian Linux (CuBox-i1, CuBox-i2, CuBox-i2eX, or a CuBox-i4Pro)
After installing Debian Linux on the CuBox-i1, CuBox-i2, CuBox-i2eX, or CuBox-i4Pro, additional firmware files are required for Wi-Fi, SDMA, and hardware-accelerated video decoding. Specifically, the VPU needs proprietary firmware, the Wi-Fi module relies on symlinking files from an official Debian package, and the SDMA engine depends on the non-free firmware package. For context, the following dmesg output from a CuBox-i4Pro demonstrates the missing firmware warnings: This article explains h...| James Cherti

Simple sudo settings to prevent unwanted Linux or UNIX privilege escalation: Per-command sudo authentication and path restriction
The default sudo configuration caches successful authentication using a timestamp, allowing commands to execute without a password prompt for a limited period. This can cause security risks, such as local privilege escalation if an attacker accesses an unlocked terminal session or if a malicious script automatically escalates its own privileges within the cached timeframe. Additionally, restricting the execution path ensures that sudo only executes verified, system-installed packages. Here is...| James Cherti
