A high load average, low “free” memory, or busy disk is a clue—not a root cause. Use interval-based Linux tools to separate CPU saturation, memory reclaim, swap, storage latency, network load, process behavior, and cgroup pressure before restarting or killing anything.
Netdata is a lightweight, open-source system performance monitoring agent for Linux. It collects thousands of metrics per second—including CPU usage, RAM allocation, disk I/O, network throughput, and container stats—and renders them in a real-time web dashboard without high CPU overhead.
Master essential open-source Linux performance and debugging tools: strace, ltrace, perf, Valgrind, iostat, ss, and iperf3 with command workflows.
Function in C programming is a group of statements which are separated from main task for the … Read more
Microprocessors and microcontrollers are both crucial components in digital systems, but they serve different purposes and are … Read more
Discover why arrays are essential in C: contiguous memory allocation, O(1) index math, CPU cache line prefetching, and hardware DMA buffers.
USB-C describes a connector—not a guaranteed data rate, display mode, or charging power. This guide separates the physical conductors, USB 2.0/3.2/USB4 signaling, host-controlled topology, descriptors, endpoints, enumeration, and power negotiation that determine what a connection can actually do.
Embedded Linux development boards are essential tools for developers working on embedded systems projects. These boards offer … Read more
Configure OBS Studio on Ubuntu for dependable screen recordings, audible tracks, recoverable files, and a short verification run before the real session.
Embedded Linux development requires a diverse set of tools to facilitate efficient coding, debugging, and deployment. Whether … Read more
LOCAL_LDLIBS is appropriate for stable NDK system libraries such as log or z. External libraries should normally be declared as source-built or prebuilt ndk-build modules so headers, ABI selection, dependency order, packaging, and runtime loading remain reproducible.
Create a temporary audio loopback from a named microphone source to a named speaker or headphone sink using pactl. Start at a conservative volume and latency, save the returned module ID, unload that module to stop monitoring, and control acoustic feedback before turning anything up.
If your are working to port the kernel versions or port the kernels to different platforms, during … Read more
Master C function pointers: learn syntax, typedef declarations, qsort() callbacks, POSIX signal handlers, kernel vtables, and memory mechanics.
New AWS customers now choose a Free account plan or Paid account plan; the old blanket “12 months free” description no longer applies to accounts opened after July 15, 2025. Learn what each plan permits, how credits expire, and which security and billing controls to configure before launching anything.
Installing Chrome is the easy part. This walkthrough also checks the CPU architecture, package origin, APT repository, update candidate, launcher, and the profile data an uninstall leaves behind.
Android’s `Build` and `Build.VERSION` APIs expose platform and firmware metadata, but those values serve different purposes. Use the numeric API level for compatibility checks, treat display strings as diagnostics, and avoid turning hardware fields into tracking identifiers.
An apt or dpkg lock usually means another package operation is already protecting the package database. Do not delete the lock file. Identify the owner, let healthy updates finish, terminate only a genuinely frozen frontend, then complete pending configuration and dependency repair.
