10 months ago
- Bcachefs changes, including a new 'journal_rewind' feature for disaster recovery, were merged into Linux 6.16.
- Linus Torvalds initially criticized the Bcachefs pull request but later merged it without further commentary.
- The merged code will be part of Linux 6.16-rc4, set for release on Sunday.

Adding a trash can to Linux with trash-CLI
10 months ago
- Linux CLI lacks a trash can, but trash-cli provides a solution for safely removing and recovering files.
- Installation of trash-cli is possible via multiple methods, with instructions available on GitHub.
- Using aliases for trash-cli commands is recommended, but overwriting 'rm' can cause issues.
- Files can be moved to trash using 'trash' or 'trash-put', with suggested alias 'tm'.
- View trash contents with 'trash-list' (alias 'tmls') and search with 'trash-list | grep -i' (alias 'tmgr').
- Trashed items are stored in '~/.local/share/Trash/files' or '/root/.local/share/Trash/files' for sudo operations.
- Check trash disk usage with 'du -sh ~/.local/share/Trash/files' (alias 'tmdu').
- Recover trashed items using 'trash-restore' (alias 'tmre'), but cannot overwrite existing files.
- Empty the trash with 'trash-empty' (no confirmation) or 'trash-empty n' to remove items older than 'n' days.
- Remove specific items from trash with 'trash-rm', though path-based removal may not work.
- Automate trash cleanup with cron jobs, e.g., '20 4 * * * trash-rm 7' to run daily at 4:20 AM.
- The tool is highly recommended for its file recovery capabilities, despite minor inconveniences on unmanaged systems.

Making a speedrun timer in D
10 months ago
- The author created a custom speedrun timer for Deus Ex to implement features like auto-splitting and load time removal.
- The timer was developed in the D programming language due to its system-level capabilities and high-level features.
- Initial attempts to find a loading flag in memory failed, leading to a more complex approach involving code injection.
- Key Linux syscalls like `ptrace` and `process_vm_readv` were used to interact with the game's memory.
- The `LoadMap` function in Deus Ex was identified and modified to set a custom loading flag.
- A safe memory location within the game's process was found to store the loading flag and map name.
- The timer includes logic to detect loading screens and automatically pause the timer.
- Autosplitting was implemented by tracking the current map name returned by `LoadMap`.
- Challenges included handling exceptions during loading and optimizing memory access to reduce game stutter.
- Future improvements could involve more efficient signaling mechanisms and support for save time removal.
Building Linux kernel on macOS natively
10 months ago
- Building Linux kernel on macOS natively is possible with some adjustments.

- Clang Built Linux allows using LLVM tools (clang, lld) instead of GCC and GNU binutils.
- Missing headers like 'elf.h' and 'byteswap.h' can be resolved using Homebrew packages and custom includes.
- Incompatible 'uuid_t' and 'sed' issues were fixed with patches and GNU sed.
- Successful build achieved for RISC-V and AArch64 architectures.
- macOS shows faster clean build times but slower incremental builds compared to Linux (Docker Desktop).
- Build issues primarily stem from scripts, not the kernel itself, making them easier to address.

Memstop: Use LD_PRELOAD to delay process execution when low on memory
10 months ago
- Memstop is a lightweight LD_PRELOAD shared object that delays process execution when system memory is critically low.
- It monitors available memory and waits until a configurable percentage is available before allowing the application to start.
- Designed to prevent crashes caused by memory exhaustion in parallel processing systems.
- Useful in parallel build systems (like make -j), batch processing systems, and high-memory applications.
- When loaded via LD_PRELOAD, it runs before the application's main() function and all subprocesses.
- Reads system memory from /proc/meminfo, calculates required available memory (default: 10%), and waits until conditions are met.
- Build requirements: GCC compiler, Linux system with /proc/meminfo support, and Make.
- Installation involves building the shared library (memstop.so) and placing it in a library path.
- Configured using environment variables: MEMSTOP_PERCENT (default: 10, range: 0-100) and MEMSTOP_VERBOSE (for verbose output).
- Verbose mode outputs memory statistics and blocking status but can interfere with normal execution.
- Licensed under GNU General Public License v3.0 (GPLv3).

- Critics argue systemd lacks flexibility and makes Linux less modular, while proponents highlight its improvements in service management and scalability.
Systemd's Nuts and Bolts – A Visual Guide to Systemd
10 months ago
- Systemd is a comprehensive suite of tools for managing modern Linux systems, integrating D-Bus for IPC and cgroups for process management.
- D-Bus (Desktop Bus) is a high-level message-passing mechanism for Inter-Process Communication (IPC), optimized for processes on a single machine.
- Systemd uses cgroups (control groups) extensively for resource isolation and management, ensuring security and process tracking.
- Systemd organizes processes into a hierarchy of cgroups, with types like .slice, .service, and .scope for different management needs.
- Systemd units are declarative configuration files that define what should be done, not how, with types including .service, .socket, .target, and .timer.
- Unit files are simple .ini-style text files with sections like [Unit], [Install], and type-specific sections like [Service] or [Timer].
- Systemd's journal (systemd-journald) collects logs from various sources, storing them in a structured, indexed binary format for easy querying.
- The systemctl command is the primary interface for interacting with systemd, allowing users to inspect, start, stop, and manage units.
- Systemd's socket activation allows services to be started on-demand when traffic arrives on a socket, improving boot times and resource usage.
- Timer units in systemd replace cron jobs, offering more flexible scheduling options with calendar-based and monotonic timers.
