Sorting algorithms, searching, trees, graphs, dynamic programming, and algorithmic problem solving.
As C++ projects grow, understanding the web of dependencies between libraries and executables becomes critical for maintenance, build optimization, and architectural decisions. Graphviz provides a straightforward way to visualize your CMake build structure as a dependency graph. How It Works CMake can generate .dot files that describe relationships between targets (libraries, executables, and custom targets)….
The Dynamics 365 development tooling landscape has shifted significantly since the early VS 2017 days. While Jason Lattimer’s original D365DeveloperExtensions extension is no longer actively maintained, modern alternatives have emerged that handle web resource deployment more reliably. This guide covers current approaches and best practices for streamlining web resource workflows in Visual Studio. Modern Alternatives…
The standard sort command is single-threaded by default, which limits performance on modern multi-core systems. Several approaches exist to speed up sorting operations using parallelism. GNU Sort with Parallel Sorting Modern versions of GNU sort (8.23+) include built-in parallel sorting support. Enable it with the –parallel flag: sort –parallel=4 large_file.txt > sorted_output.txt The –parallel option…
When the kernel migrates a process from one CPU’s runqueue to another, the Completely Fair Scheduler (CFS) must adjust the process’s virtual runtime (vruntime) to account for the different scheduling histories of each CPU. This prevents fairness issues where a migrated process could gain an unfair advantage on the destination CPU. How vruntime Adjustment Works…
When using recursive make invocations, GNU make prints “Entering directory…” and “Leaving directory…” messages for each nested call. These messages clutter build output and make logs harder to read, especially in projects with deeply nested makefiles. The problem By default, GNU make prints these messages to help track execution flow in complex builds. For a…
The simplest way to see your commit history as a tree structure: git log –graph –oneline This produces a text-based graph showing branch relationships and merges with abbreviated commit hashes: * b5dc8b9 Merge branch ‘main’ into develop |\ | * 7514ef1 revised the README.md | * 6692428 align size to page for both shalloc and…
The built-in etags command doesn’t recursively traverse directories by default, but generating TAGS files across your entire project is straightforward with the right tools and setup. Using ctags (Recommended) The simplest approach is ctags with the -e flag, which generates Emacs-compatible TAGS files: ctags -e -R . The -R flag enables recursive traversal. This works…
When converting PostScript to PDF using ps2pdf with certain PDFSETTINGS options, you may hit this error: GPL Ghostscript 9.10: Set UseCIEColor for UseDeviceIndependentColor to work properly. Unrecoverable error: stackunderflow in .setdistillerparams This occurs when Ghostscript’s internal stack runs out of expected values during PDF distiller parameter processing. The root cause is usually conflicting color space…
By default, Vim performs case-sensitive searches. When you need case-insensitive matching, you have several approaches depending on your use case. Global Case-Insensitive Search To enable case-insensitive search globally: :set ignorecase You can also use the shorthand: :set ic To toggle it back: :set noignorecase Note: The ignorecase setting affects both search and substitution commands. If…
Filtering dependent fields based on parent field values is a common requirement in Dynamics 365 CRM. This guide walks through implementing conditional filtering so the salutation dropdown only shows values relevant to the selected gender. Prerequisites Access to a Dynamics 365 environment (2016 or later) with customization rights Basic understanding of option sets and form…
Filtering a dependent lookup field based on another lookup field’s value is a core requirement in Dynamics 365 and Power Apps. The classic example: a Lead entity with Branch and Sub Branch fields where Sub Branch options should only display records matching the selected Branch. The form editor handles this natively—no plugins or JavaScript required….
Converting a managed solution to unmanaged in on-premise Dynamics CRM requires direct database modification. You’ll need this when customizing third-party solutions that the publisher hasn’t provided in unmanaged form, or when you need to export and modify components before deployment. Prerequisites Full database backup (this modifies system tables — non-negotiable) SQL Server Management Studio or…
When building applications requiring fast key-value lookups, hash tables are fundamental. C offers several options—from POSIX standard library functions to specialized third-party libraries. The right choice depends on your dataset characteristics, memory constraints, and whether you need dynamic resizing. Standard Library: hsearch() The simplest option is hsearch() from <search.h> in POSIX-compliant systems. It provides basic…
