Career Ops is an open-source platform designed to help individuals manage their job search process with a structured, operations-style approach that treats career development like a pipeline. It provides a system for organizing job applications, tracking progress across different stages, and maintaining visibility into opportunities, much like a lightweight CRM tailored for job seekers. The project emphasizes clarity and accountability, enabling users to monitor applications, follow-ups, and outcomes in a centralized environment. It is typically built with modern web technologies, allowing for easy customization and self-hosting by developers who want full control over their data. Career Ops focuses on reducing the chaos and fragmentation that often comes with job searching by introducing a repeatable workflow that can be iterated and improved over time. It also supports the idea of data-driven job searching.

It is designed to be lightweight, easy to deploy with Docker, and configurable for both personal and hosted use cases. The platform supports browser-level integration so users can set it as their default search engine for quick access. Its architecture emphasizes privacy by avoiding tracking and minimizing data collection while still enabling advanced AI features. Overall, MiniSearch targets users who want a self-hosted, Perplexity-style search experience with strong control over data and models.

zoekt is a fast, scalable code search engine written in Go that builds compressed indexes (shards) for source repositories and serves low-latency regex and substring queries. It optimizes for developer workflows: refresh indexes from Git, search across many repos instantly, and jump into hits with surrounding context and file navigation. The indexer uses efficient n-gram dictionaries and posting lists to keep query latency low, while storing metadata (branch, language, repo) for precise filtering. A built-in web UI and JSON API enable both interactive exploration and integration into editors and other tools. It supports ranking heuristics such as path weighting and symbol awareness to surface likely matches first, even in monorepos. Incremental and parallel indexing let it keep up with active codebases, making it suitable for both local deployments and multi-tenant service setups.

FTimes is a forensic system baselining, searching, and evidence collection tool. Its primary purpose is to gather and/or develop topographical information and attributes about specified directories and files in a manner conducive to intrusion and forensic analysis.

SCAN (Smart Content Aggregation and Navigation) is a universal semantic content aggregator. It combines search, text analysis, tagging and metadata functions to provide new user experience of desktop navigation and document management.

disk manager is a CD/DVD archiving tool. It storys the directory contents of any media so you can search it later. Its also designed as file explorer which makes it easy to find big files. Windows Version supports native file context menus.

This is a autorun menu for cd's. It link a name with a file and a short description. It can execute/open files, copy directories, execute commands, etc and it is really easy to use. (Spanish)

PDFcat - Portable Document (PDF) Catalog Manager

This is a python based UI application that can rename a part of a set of files inside a directory based on the provided regular expression. This gives a lot more flexibility compared to other renaming files since it used grouping principle. This had two level of applying the rename, first stage shows who it will be when you rename it, if you are fine with the change you can make it permanent by clicking commit. This avoid the risk of file getting corrupted. To rename all .py file to .pyc is as follows: Search for Regex: (.py)$ Rename using this regex: .pyw

A simple full text search tool that finds files matching a search expression in a directory tree.

HashCatalog is a program that can find duplicate files in one or more folders, or between 2 lists of one or more folders. HashCatalog can also create an xml database file containing a listing of files with hashes.

Write programs as graphical dataflow charts instead of text. Compile them to any programming language you want. Besides this project includes the most efficient tree-based sorting algorithm that is possible. Originally developed on a CTOS Color NGEN, at first in Pascal, later ported to C, finally - 20 years later - ported to Linux. Currently it's still not really system independent. But it's intended that further releases will cure this.
