The zram kernel module creates RAM-based block devices named /dev/zram<id> (<id> = 0, 1, ...). Pages written to these disks are compressed and stored in memory itself. These disks allow very fast I/O and compression provides good amounts of memory saving https://t.co/0w5AgORq1F
Difference: initrd VS initramfs #Linux. Initrd is a fixed-size block device, which requires to be 'formatted' by a filesystem such as ext2. It cannot be enlarged or shortened. On the other hand, initramfs is a cpio archive which can be resized as needed. https://t.co/aoZLdhXmhA
Difference between Jenkins and Gitlab - Jenkins is free and GITLAB is tiered. GITLAB supports in-repo YAML configuration, which allows customization of CI/CD piplelines https://t.co/nOYkCErAcu #AUTOMATION
catp - A neat little tool that print logs of a _running_ process. Useful if you need logs of process who's logs were redirected to /dev/null. https://t.co/dBuj2zJeow
Stressful Application Test (or stressapptest #Linux ) is a memory interface test. It tries to maximize randomized traffic to memory from processor and I/O, with the intent of creating a realistic high load situation #embedded https://t.co/ykWLCh7Vgu
Programming with portable data types in embedded systems - ensures that the datatypes have the same memory footprint across different architectures e.g. uint8_t is the same on all #embedded platforms #Linux#programming https://t.co/Z4Yu6F4WzY
