  • Microsoft Line of Code Counter: Tips, Tricks, and Best Practices

    Top Features of Microsoft Line of Code CounterThe Microsoft Line of Code Counter is a tool designed to help developers, team leads, and managers measure source code size and composition across projects. Though several tools exist for counting code, Microsoft’s offering integrates with the ecosystem many organizations already use, providing convenience, accuracy, and actionable metrics. Below is a detailed look at its top features, why they matter, and practical tips for getting the most from them.

    1. Accurate Language-aware Counting

    One of the core strengths is language-aware counting. The tool recognizes a wide range of programming and scripting languages and applies language-specific rules to produce meaningful line counts.

    • It distinguishes between code, comments, and blank lines.
    • Handles multi-line comments, nested comments (where applicable), and language-specific comment conventions.
    • Supports modern and legacy languages commonly found in enterprise codebases (C#, VB.NET, C++, JavaScript, TypeScript, Python, PowerShell, HTML, CSS, SQL, and more).

    Why it matters: Raw line counts can be misleading; knowing how many lines are actual executable code versus comments or whitespace gives more truthful productivity and size metrics.

    2. Integration with Visual Studio and Azure DevOps

    The counter integrates tightly with Microsoft developer platforms.

    • Visual Studio extension: run counts directly from the IDE, view results per-project or per-solution, and drill into files from the results window.
    • Azure DevOps pipeline tasks: produce counts as part of CI/CD runs, attach results as pipeline artifacts, or fail builds based on thresholds.
    • Git integration: analyze counts at a commit, branch, or pull request level.

    Why it matters: Integration streamlines workflows so teams can gather metrics without leaving their familiar tools, enabling automated tracking and gatekeeping.

    3. Granular Filtering and Scoping

    The tool offers flexible scoping so you can focus metrics where it matters.

    • Include/exclude files by pattern, folder, or file type.
    • Scope by project, solution, repository, or branch.
    • Exclude generated code or third-party libraries to focus on your source.

    Why it matters: Large repositories often include generated artifacts or vendor code that distort metrics. Granular filters let you isolate the code you actually own and maintain.

    4. Detailed Reporting and Export Options

    Results are presented in comprehensive, exportable reports.

    • Summary dashboards showing total lines, code/comment/blank breakdown, and language distribution.
    • Per-file and per-folder breakdowns with sortable columns.
    • Export to CSV, JSON, or HTML for further analysis or archival.
    • Visual charts (pie, bar, trend) for presentations and management reporting.

    Why it matters: Exportable, visual reports make it easier to share findings with stakeholders and feed other tools (e.g., BI dashboards).

    The counter can track code size over time.

    • Store snapshots per build or per chosen interval.
    • Compare current counts to historical baselines.
    • Generate trend charts showing growth, shrinkage, or sudden changes.

    Why it matters: Trend data reveals long-term patterns—codebase bloat, effects of refactoring, or the impact of large merges—helping teams make informed decisions.

    6. Thresholds, Alerts, and Quality Gates

    Built-in policy features let teams enforce size-related rules.

    • Define thresholds (e.g., max lines per file, max total lines per module).
    • Fail builds or raise warnings when thresholds are exceeded.
    • Combine with other metrics (test coverage, static analysis) for comprehensive quality gates.

    Why it matters: Automatic enforcement prevents regressions (like code bloat) and helps maintain agreed-upon standards across the team.

    7. Performance and Scalability

    Designed for enterprise repositories.

    • Fast scanning with parallel file processing.
    • Efficient handling of very large repositories (millions of lines).
    • Incremental scanning options to analyze deltas instead of full repos every run.

    Why it matters: Speed and scalability keep the tool practical in large-scale environments where full scans could otherwise be prohibitively slow.

    8. Customizable Language and Rule Definitions

    For organizations with internal languages or atypical file formats, customization is available.

    • Define new language profiles with comment markers and file extensions.
    • Add rules for what counts as code vs. non-code.
    • Map custom file types to existing language rules.

    Why it matters: Flexibility ensures accuracy even in specialized codebases, preventing misclassification and misleading metrics.

    9. Security and Compliance Considerations

    Counting tools often need to run in secure environments; Microsoft’s solution respects enterprise constraints.

    • Can run entirely on-premises or within controlled Azure subscriptions.
    • Integrates with existing identity and access controls (Azure AD).
    • Results and artifacts can be restricted to authorized teams.

    Why it matters: Enterprises with strict compliance needs can still use automated metrics without exposing source or metadata inadvertently.

    10. Ease of Use and Documentation

    The product balances advanced features with approachable UX.

    • Quick-start wizards for initial configuration.
    • Contextual help in the IDE and pipeline tasks.
    • Detailed documentation and examples for common scenarios.

    Why it matters: Faster setup lowers friction for adoption across teams, and good docs reduce support overhead.

    Practical tips for teams

    • Exclude generated and vendor code by default to keep metrics meaningful.
    • Use CI snapshots to track trends and detect sudden changes after merges.
    • Combine line counts with other metrics (complexity, coverage, code review velocity) for a fuller picture of quality.
    • Set conservative thresholds initially and adjust as you learn normal variation for your codebase.
    • Regularly review language mappings if you add new file types or build tools.

    The Microsoft Line of Code Counter provides language-aware counting, tight Microsoft tooling integration, flexible scoping, strong reporting, historical trend support, enforcement features, scalability, customization, and enterprise-friendly security. These features make it a practical choice for teams that want reliable, actionable code-size metrics within the Microsoft ecosystem.

  • Customize Your Workflow: Creating and Managing Hotkeys

    Hotkeys for Faster Productivity: A Beginner’s GuideHotkeys — keyboard shortcuts that trigger commands without using menus or a mouse — are one of the simplest, highest-ROI habits you can adopt to work smarter. This guide explains why hotkeys matter, introduces the most useful shortcuts for major operating systems and common apps, shows how to learn and customize hotkeys, and offers practical tips to build the habit so you get noticeably faster with everyday tasks.

    Why hotkeys matter

    • Speed: Hitting a key combination is usually faster than moving your hand to the mouse and navigating menus.
    • Flow: Keyboard use reduces interruptions and context switching, helping you stay focused.
    • Ergonomics: Less mouse time can reduce repetitive strain for some users.
    • Consistency: Many shortcuts are shared across apps and OSes; once learned, they transfer.

    How to approach learning hotkeys

    Start small and practice deliberately:

    1. Pick 3–5 shortcuts that solve your most frequent tasks (e.g., copying, switching windows, undo).
    2. Force yourself to use only the keyboard for those tasks for a week.
    3. Add more shortcuts gradually.
    4. Use reminder overlays, printable cheat sheets, or software that displays shortcuts until they become automatic.

    Micro-practice beats cramming — aim to make a handful of shortcuts automatic in a week.

    Core hotkeys that every beginner should learn

    These are cross-platform essentials (adjust modifier keys per OS — Ctrl on Windows/Linux, Cmd on macOS):

    • Copy — Ctrl/Cmd + C
    • Paste — Ctrl/Cmd + V
    • Cut — Ctrl/Cmd + X
    • Undo — Ctrl/Cmd + Z
    • Redo — Ctrl/Cmd + Y (or Shift + Ctrl/Cmd + Z in many apps)
    • Find — Ctrl/Cmd + F
    • Select all — Ctrl/Cmd + A
    • Save — Ctrl/Cmd + S
    • Open — Ctrl/Cmd + O
    • New — Ctrl/Cmd + N

    Practice these until they’re reflexive — they’re used in nearly every application.

    Window and application management

    Efficiently switching and arranging windows saves time when multitasking.

    Windows (Windows ⁄11):

    • Switch apps — Alt + Tab
    • Cycle through windows of current app — Alt + Esc
    • Snap window left/right — Win + Left / Win + Right
    • Maximize/restore — Win + Up / Win + Down
    • Show desktop — Win + D

    macOS:

    • Switch apps — Cmd + Tab
    • Cycle windows within app — Cmd + ` (backtick)
    • Mission Control (overview) — Ctrl + Up Arrow
    • Split View — Hold green maximize button, or use Mission Control to drag

    Linux (varies by desktop environment, GNOME/KDE examples):

    • Switch apps — Alt + Tab
    • Workspace switch — Ctrl + Alt + Arrow keys
    • Tiling/snapping — Often Alt + F7 / Win + Arrow (DE-dependent)

    Browser hotkeys (works across Chrome, Firefox, Edge, Safari with small differences)

    • Open new tab — Ctrl/Cmd + T
    • Close tab — Ctrl/Cmd + W
    • Reopen closed tab — Ctrl/Cmd + Shift + T
    • Jump to tab (1–8) — Ctrl/Cmd + 1..8
    • Open history — Ctrl/Cmd + H
    • Open downloads — Ctrl/Cmd + J
    • Find on page — Ctrl/Cmd + F
    • Focus address bar — Ctrl/Cmd + L / Alt + D

    Text editing and writing boosts

    • Move cursor by word — Ctrl + Arrow (Option + Arrow on macOS)
    • Delete word — Ctrl + Backspace (Option + Backspace macOS)
    • Jump to start/end of line — Home / End (Cmd + Left/Right on macOS)
    • Format bold/italic/underline — Ctrl/Cmd + B / I / U
    • Insert line break without submitting (chat forms) — Shift + Enter

    Email and calendar shortcuts (Gmail, Outlook basics)

    Gmail (enable keyboard shortcuts in settings):

    • Compose — C
    • Send — Ctrl/Cmd + Enter
    • Reply — R
    • Archive — E
    • Search mail — / (focuses search box)

    Outlook (desktop/web):

    • New mail — Ctrl/Cmd + N
    • Send — Ctrl/Cmd + Enter
    • Reply — Ctrl/Cmd + R
    • Forward — Ctrl/Cmd + F

    IDEs and code editors (VS Code, IntelliJ basics)

    Developers gain huge time savings with editor shortcuts:

    VS Code:

    • Command palette — Ctrl/Cmd + Shift + P
    • Open file — Ctrl/Cmd + P
    • Toggle terminal — Ctrl/Cmd + `
    • Find in files — Ctrl/Cmd + Shift + F
    • Format file — Shift + Alt + F (or equivalent)

    IntelliJ:

    • Search everywhere — Double Shift
    • Find action — Ctrl/Cmd + Shift + A
    • Run — Shift + F10

    Customizing and creating hotkeys

    Why customize: match shortcuts to your workflow, resolve conflicts, or add macros for repetitive sequences.

    • Windows: Settings > Keyboard > Shortcuts or use PowerToys (Keyboard Manager) to remap keys. AutoHotkey allows powerful custom scripts and macros.
    • macOS: System Settings > Keyboard > Shortcuts to remap app or system shortcuts. Use BetterTouchTool or Keyboard Maestro for advanced macros.
    • Linux: Desktop environment settings (GNOME/KDE) let you add custom shortcuts; use tools like xbindkeys for deeper customization.

    Example AutoHotkey script (Windows) to remap Caps Lock to Ctrl:

    Capslock::Ctrl

    Example macOS Automator/Keyboard Maestro use cases:

    • One-key snippet expansion for email replies
    • Single shortcut to open a set of apps and arrange windows

    Hotkeys for accessibility and power users

    • Sticky keys (toggle modifiers without holding) — useful for limited mobility. Windows: Settings > Accessibility > Keyboard. macOS: Accessibility > Keyboard.
    • Text expansion and clipboard managers (PhraseExpress, TextExpander, aText, macOS built-in text replacements) reduce repetitive typing.
    • Voice commands (Dragon, built-in OS voice control) can complement hotkeys.

    Building the habit — a 30-day plan

    Week 1: Learn and force-use the 6–8 core shortcuts (copy/paste/undo/save/find/switch tabs).
    Week 2: Add window management and browser tab shortcuts.
    Week 3: Learn app-specific shortcuts you use daily (email, editor).
    Week 4: Customize 1–2 hotkeys and install a small tool (clipboard manager or text expander).
    Daily: 5–10 minutes of deliberate practice; track time saved roughly to reinforce motivation.

    Common pitfalls and how to avoid them

    • Trying to learn too many at once — focus on high-impact ones.
    • Conflicts between app and OS shortcuts — resolve by remapping or choosing alternatives.
    • Ignoring ergonomics — ensure shortcuts don’t force awkward hand positions; remap if needed.

    Quick reference cheat sheet (most universal)

    • Copy: Ctrl/Cmd + C
    • Paste: Ctrl/Cmd + V
    • Undo: Ctrl/Cmd + Z
    • Save: Ctrl/Cmd + S
    • Find: Ctrl/Cmd + F
    • New tab/window: Ctrl/Cmd + T / Ctrl/Cmd + N
    • Switch app: Alt + Tab (Win) / Cmd + Tab (macOS)

    Hotkeys are small changes with outsized returns. Start with a few, practice deliberately, and expand. In weeks you’ll feel smoother, faster, and less interrupted—your keyboard will feel more like a direct extension of your intent.

  • Excel Calendar Maker: Design Editable Calendars & Export to Print

    Calendar Maker for Excel: Build Printable, Editable Calendars FastCreating professional, printable, and editable calendars doesn’t require expensive software or design skills. With a calendar maker for Excel, you can rapidly produce customized monthly, yearly, or weekly planners that fit your needs—whether for home, business, classroom, or marketing. This article walks you through why Excel is a strong choice, features to look for in a calendar maker, step-by-step instructions to create one quickly, customization tips, printable/export options, and examples for specific use cases.

    Why use Excel for calendar creation?

    • Familiar interface: Many people already know Excel basics—entering data, formatting cells, and using templates—so the learning curve is low.
    • Flexible layout control: Excel’s grid naturally matches calendar layouts, making it easy to place dates, events, and notes precisely.
    • Easy editing: Update dates, add events, or change formatting without rebuilding the calendar.
    • Automation with formulas: Use formulas to compute dates, weekdays, and highlight holidays automatically.
    • Printable output: Excel prints reliably to standard paper sizes; you can fine-tune margins and scaling for high-quality hard copies.

    Essential features of a calendar maker template

    A good calendar maker template for Excel should include:

    • Automatic date generation for any month/year.
    • Weekday headers that adjust to chosen locale (Sunday or Monday start).
    • Printable layout with page-break-aware formatting (monthly or yearly views).
    • Editable cells for events, notes, or tasks.
    • Conditional formatting to highlight weekends, holidays, or special dates.
    • Option to add images or logos for branding (useful for businesses and schools).
    • Support for multiple languages or regional date formats (optional).

    Quick setup: Build a basic editable, printable calendar in Excel (step-by-step)

    Follow these concise steps to create a functional monthly calendar that’s editable and print-ready.

    1. Set up the sheet

      • Create a new workbook. Rename the first sheet “Calendar-Monthly” or similar.
      • Set the page layout to Portrait or Landscape depending on your preferred look. Adjust margins to Narrow for more space.

    2. Prepare the grid

      • Reserve the top rows for the month/year title and controls (e.g., cells where you enter Month and Year).
      • Create a 7-column wide grid for weekdays. Below the weekday headers, allocate 6 rows for date cells (to cover months that span six weeks).
      • Make each date cell a merged block if you want more space (e.g., merge each cell across several rows to allow notes).

    3. Add controls for month and year

      • In two dedicated cells (say B1 for Year and B2 for Month number or name), enter the year and month inputs. Use data validation for Month if you want a dropdown list of month names.

    4. Generate the first day and fill dates with formulas

      • Use a formula to get the first day of the month:
        • Example (cell B4 named StartDate): =DATE(B1, MATCH(B2, {“January”,“February”,“March”,“April”,“May”,“June”,“July”,“August”,“September”,“October”,“November”,“December”},0), 1)
      • Calculate the weekday offset to place the first date in the correct weekday column:
        • Example (cell B5): =WEEKDAY(B4, 1) — where 1 means Sunday=1, Monday=2, etc. Adjust if using Monday start with WEEKDAY(…,2).
      • Fill the calendar cells with incremental date formulas. For a cell representing the top-left calendar slot (A7), use:
        • =IF( (ROW()-start_row)*7 + COLUMN()-start_col + 1 – offset <= 0, “”, DATE(B1, B2_number, (ROW()-start_row)*7 + COLUMN()-start_col + 1 – offset) )
      • Alternatively, compute each cell date as: =IFERROR(IF(date<=EOMONTH(StartDate,0), date, “”), “”) where date references previous cell + 1 or StartDate – offset + column_index.

    5. Format date display and make cells editable

      • Use custom number formats to show day numbers only (e.g., d) and reserve space beneath for event text.
      • Apply Wrap Text to event sections. Use unlocked cells (Protection tab) if you plan to protect the structure but allow editing.

    6. Add conditional formatting

      • Highlight weekends: apply a rule that checks WEEKDAY(cell_date,1)>5 and set background color.
      • Highlight today’s date: =AND(cell_date=TODAY()) with distinct formatting.
      • Mark holidays: set a named range listing holiday dates and use =COUNTIF(Holidays,cell_date)>0.

    7. Make it printable

      • Set Print Area to include only the calendar grid and header.
      • Use Page Setup: Fit to 1 page wide (and 1 tall for monthly single-page calendars) or use scaling to control print size.
      • Add Headers/Footers for month name, year, page numbers, or branding.

    Advanced enhancements

    • Add a yearly overview sheet that auto-generates 12 months laid out in a grid. Use the same formulas but offset month numbers with DATE(B1, n, 1) where n ranges 1–12.
    • Insert macros (VBA) or Office Scripts to create a “Create Calendar” button that produces a new sheet for any selected month/year automatically.
    • Integrate event import: parse a CSV or pull from Outlook/Google Calendar (requires additional scripting) to populate events.
    • Build printable planners: add separate sections for notes, to-dos, and habit trackers that align with each month.

    Design and customization tips

    • Keep contrast high for printed copies: dark text on light background prints best. Avoid subtle pastel fills that may not show on some printers.
    • Use a clean sans-serif font (Calibri, Arial) for readability. For decorative headers, use a single display font.
    • Reserve color for meaning — e.g., red for holidays, blue for meetings — and document the color key on the sheet.
    • Use column widths and row heights that approximate square day boxes for a balanced look. Use Excel’s Page Break Preview to ensure no awkward splits across pages.

    Exporting and sharing

    • Save as XLSX for full editability.
    • Export to PDF for universally printable, non-editable copies (File > Export or Save As > PDF). Use High Quality printing settings for better fidelity.
    • To share with others for editing, upload to OneDrive and use Excel Online, or save to Google Sheets (some formula compatibility caveats).

    Example use cases

    • Personal planners: Track birthdays, appointments, and goals with space for notes.
    • Small businesses: Brand the calendar with a logo, include business hours, and print for customers.
    • Teachers and schools: Produce academic monthly planners with highlighted holidays and exam dates.
    • Marketing teams: Create monthly content calendars with color-coded campaign types.
    • Event organizers: Generate printable schedules for multi-day events or festivals.

    Troubleshooting common issues

    • Dates not aligning correctly: check WEEKDAY parameters and whether your month input is numeric or text.
    • Printing cuts off edges: adjust margins and check Print Area and scaling (Fit to 1 page wide).
    • Conditional formatting not applied: ensure rules reference actual date values (not text) and use absolute/relative references consistently.

    Quick resources (formulas to copy)

    • First day of month: =DATE(year_cell, month_number_cell, 1)
    • Last day of month: =EOMONTH(first_day_cell,0)
    • Weekday of a date (Sunday=1): =WEEKDAY(date_cell,1)
    • Check if date is within month: =AND(date_cell>=first_day, date_cell<=EOMONTH(first_day,0))

    Building a calendar in Excel with a calendar maker approach gives you fast, editable, and printable results tailored to your exact needs. Start with a simple monthly template, then add automated formulas, conditional formatting, and print settings—within an hour you can have a reusable calendar system that scales from personal use to business distribution.

    5. Deploying Applications

    FaJo XP FSE uses containerization for most services.

    Using Prebuilt Images

    • The Console includes an App Marketplace with prebuilt images (media server, ML runtime, reverse proxy, etc.).
    • Select an app, configure ports/volumes/environment variables, and deploy with one click.

    Deploying Custom Containers

    • Upload your container image to a registry (private registry supported).
    • In the Console, create a new service: specify image, resource limits (CPU, memory), environment variables, and mounts.
    • Use restart policies and health checks to ensure resilience.

    Example container resource spec:

    • CPU limit: 2 cores
    • Memory limit: 4 GB
    • Restart policy: on-failure (max 5 retries)

    6. FSE (Fault-Safe Engine) Details

    The FSE provides redundancy and high availability features:

    • Watchdog monitors: auto-restart misbehaving services.
    • Service replication: run primary and secondary instances (active-passive) with automatic failover.
    • Persistent state synchronization: sync configuration and selected data to peer devices or central storage.
    • Power-fail protection: optional battery-backed storage commit to reduce corruption risk.

    Configuration tips:

    • Use quorum-based failover only when you have at least three nodes to avoid split-brain.
    • Keep heartbeat intervals tuned to your network conditions — too short causes false failovers; too long delays recovery.

    7. Security Best Practices

    • Enable secure boot and disk encryption where available.
    • Use role-based access and MFA for administrative accounts.
    • Keep the device firmware and OS patched; enable automatic security updates if acceptable for your environment.
    • Limit management access to trusted IPs and use VPN for remote administration.
    • Regularly export and verify backups; test restores periodically.

    8. Monitoring and Logging

    • Local logging: system logs retained on device with rotation. Configure retention limits to avoid disk fill.
    • Remote logging: forward logs to a central SIEM or syslog collector.
    • Metrics: Prometheus-compatible metrics endpoint available for CPU, memory, network, and service health.
    • Alerts: configure thresholds (CPU > 85% for 5m, disk usage > 90%) and notification channels (email, webhook, Slack).

    9. Advanced Customization and SDK

    • FaJo provides an SDK with C, Python, and Go bindings to interact with system services, manage I/O, and extend the UI.
    • Plugins run in sandboxed containers and can register UI pages via the management API.
    • Examples included: GPIO controller, custom media pipeline, and lightweight model-serving plugin.

    Example Python snippet (pseudo):

    from fajo_sdk import DeviceClient dc = DeviceClient(auth_token="your-token") dc.create_service(image="registry.example.com/myapp:latest", cpus=1, mem_mb=512)

    10. Troubleshooting Common Issues

    • No network on first boot: check link LEDs, ensure DHCP server is active, or set a serial console static IP.
    • Service failing to start: check container logs, resource limits, and mount permissions.
    • High CPU usage: identify process in top, check for runaway containers or background jobs.
    • Disk full: rotate logs, remove unused images/containers, expand storage if supported.

    Useful commands via SSH/serial:

    • systemctl status fajo-daemon
    • journalctl -u fajo-daemon -f
    • docker ps -a / podman ps -a
    • ip addr / ip route

    11. Backup, Restore, and Firmware Upgrades

    • Backup configuration from the Console (full config export).
    • Schedule periodic backups of important volumes to a remote SFTP/SMB/NFS location.
    • Test restores on a spare device or VM before applying to production.

  • Getting Started with TCE Search: Quick Setup and First Queries

    Getting Started with TCE Search: Quick Setup and First QueriesTCE Search is a powerful search and indexing tool designed to help teams find information quickly across large datasets, codebases, and knowledge repositories. This guide walks you through setting up TCE Search, configuring its core components, and executing your first queries. It’s written for technical users and managers who want a practical, step-by-step introduction.

    TCE Search is a search platform that indexes documents, code, logs, and structured data, enabling fast, relevant retrieval. It typically provides features such as full-text search, faceted filtering, relevance tuning, and integration with data pipelines and authentication systems. Use cases include knowledge base search, enterprise document discovery, code search, and investigative analytics.

    Prerequisites

    Before starting, ensure you have the following:

    • A machine or server with at least 4 CPU cores and 8 GB RAM for small deployments (increase resources for larger datasets).
    • A supported OS (Linux distributions are most common for production).
    • Access to the data sources you want to index (file shares, databases, cloud storage, code repositories).
    • Basic familiarity with the command line, JSON/YAML configuration files, and network concepts.
    • (Optional) Docker if you prefer containerized deployment.

    Installation Options

    You can run TCE Search in several ways:

    • Local binary installation — ideal for testing and small instances.
    • Docker container — convenient for development and reproducible environments.
    • Kubernetes — recommended for scalable production deployments.
    • Managed/service offering — if available, this removes infrastructure management.

    Below are quick instructions for the two most common approaches: Docker and local binary.

    Docker (quick start)

    1. Ensure Docker is installed and running.
    2. Pull the TCE Search image: 
      
docker pull tce/tce-search:latest
    3. Run a single-node container: 
      
docker run -d --name tce-search -p 9200:9200 -p 9300:9300  -v tce_data:/var/lib/tce-search  tce/tce-search:latest
    4. Check logs: 
      
docker logs -f tce-search
    5. Visit the web UI at http://localhost:9200 (or the port TCE Search exposes).

    Local binary

    1. Download the latest release for your OS from your distribution point.
    2. Unpack and move the binary to /usr/local/bin/ (or a preferred path).
    3. Create a configuration file (example below).
    4. Start the service: 
      
tce-search --config /etc/tce-search/config.yml

    Initial Configuration

    TCE Search uses a configuration file (YAML/JSON). Key sections include:

    • network: host, ports, TLS settings
    • storage: data directories, snapshot locations
    • index_defaults: analyzers, tokenizers, mappings
    • connectors: sources to crawl/index (S3, SMB, Git, databases)
    • security: auth providers, API keys, roles

    Example minimal config (YAML):

    network:   host: 0.0.0.0   http_port: 9200 storage:   data_path: /var/lib/tce-search/data   logs_path: /var/log/tce-search index_defaults:   analyzer: standard   shards: 1   replicas: 0 connectors:   - type: filesystem     id: corpus_files     path: /data/corpus security:   api_keys_enabled: true

    After configuring, restart or launch the service and confirm the node is healthy via the health API (e.g., GET /_cluster/health).

    Ingesting Data

    TCE Search supports multiple ingestion methods:

    • Connectors (recommended) — built-in crawlers for common sources.
    • Bulk API — upload batches of documents in JSON/NDJSON.
    • SDKs and client libraries — programmatic indexing from applications.
    • Real-time pipelines — integrate with message queues (Kafka, RabbitMQ).

    Example: Filesystem connector

    Configure a filesystem connector in the connectors section (see config above). Place documents into the specified path; the connector will crawl and index file metadata and content.

    Example: Bulk API (NDJSON)

    Prepare an NDJSON file where each pair of lines represent an action and a document:

    { "index": { "_index": "kb", "_id": "1" } } { "title": "Intro to TCE Search", "body": "TCE Search is..." } { "index": { "_index": "kb", "_id": "2" } } { "title": "Config tips", "body": "Use analyzers to..." }

    Load it via curl:

    curl -XPOST 'http://localhost:9200/_bulk'    -H 'Content-Type: application/x-ndjson'    --data-binary @bulk.ndjson

    Mapping and Analyzers

    Define index mappings to control how fields are stored and searched. Common goals:

    • Full-text searchable fields (use text with analyzers).
    • Exact-match fields (use keyword).
    • Date, numeric, geo types for specialized queries.

    Example mapping snippet:

    {   "mappings": {     "properties": {       "title": { "type": "text", "analyzer": "english" },       "tags": { "type": "keyword" },       "published": { "type": "date" },       "views": { "type": "integer" }     }   } }

    Analyzers process text (tokenize, lowercase, remove stopwords, stem). Use language analyzers for better relevance.

    Running Your First Queries

    Most TCE Search deployments expose a RESTful search API. Basic query types:

    • Match query — full-text search.
    • Term query — exact match on keyword fields.
    • Range query — numeric/date ranges.
    • Bool query — combine clauses (must, should, must_not).
    • Aggregations — faceted counts, stats, histograms.

    Simple match query

    curl -XGET 'http://localhost:9200/kb/_search' -H 'Content-Type: application/json' -d' {   "query": {     "match": {       "body": "configuration tips"     }   } } '

    Filtered search with facets (aggregations)

    curl -XGET 'http://localhost:9200/kb/_search' -H 'Content-Type: application/json' -d' {   "query": { "match_all": {} },   "aggs": {     "by_tag": {       "terms": { "field": "tags" }     }   } } '

    Useful parameters

    • size — number of hits to return.
    • from — pagination offset.
    • sort — order results (relevance, date, custom score).
    • highlight — return matched snippets.

    Relevance Tuning

    Improve result quality by:

    • Choosing appropriate analyzers.
    • Using multi-field mappings (text + keyword).
    • Boosting fields: title^3, tags^2.
    • Implementing function_score for recency/popularity.
    • Adding synonyms, stopword lists, and query-time boosting.

    Example multi-field query with boosts:

    {   "query": {     "multi_match": {       "query": "search tips",       "fields": ["title^3", "body", "tags^2"]     }   } }

    Security & Access Control

    Protect your deployment:

    • Enable TLS for transport and HTTP APIs.
    • Use API keys or OAuth for application access.
    • Implement role-based access control (RBAC) for users and services.
    • Audit logs for indexing and query activity.

    Monitoring & Maintenance

    Key practices:

    • Monitor node health, CPU, memory, and disk usage.
    • Track index size, shard distribution, and merge activity.
    • Schedule snapshots/backups regularly.
    • Reindex when mappings change or to apply new analyzers.
    • Use rolling restarts for cluster upgrades.

    Troubleshooting Tips

    • Slow queries: examine slowlog, optimize mappings, add filters.
    • Indexing failures: check connector logs and document schema.
    • Out of memory: increase heap, add nodes, or reduce shard count.
    • Relevance problems: tune analyzers and boosts; add synonyms.

    Example Workflow: From Zero to Searchable KB

    1. Install TCE Search via Docker.
    2. Configure filesystem connector to /data/kb.
    3. Place Markdown and PDF files into /data/kb.
    4. Verify connector has indexed documents via GET /_cat/indices.
    5. Create mappings for title, body, tags, and published fields.
    6. Run sample match queries and add highlights.
    7. Tune relevance using boosts and an English analyzer.
    8. Set up TLS and API keys, then monitor performance.

    Conclusion

    TCE Search combines flexible ingestion, powerful query capabilities, and customization for relevance to help teams retrieve the right information fast. Start small with a single-node Docker setup, index a representative dataset, and iteratively tune mappings, analyzers, and relevance to fit your users’ needs.

  • How JSMS Is Changing Modern Web Development

    JSMS: A Beginner’s Guide to Getting StartedJSMS (short for JavaScript Message System in many contexts, though the acronym can represent different projects) is increasingly appearing in web-development conversations. If you’re new to JSMS, this guide will walk you through the core concepts, typical use cases, basic installation, a simple example, common pitfalls, and next steps to help you move from curiosity to practical use.

    What is JSMS?

    JSMS is a messaging-oriented library or pattern used to send, receive, and manage messages/events in JavaScript applications. It often aims to simplify communication between different parts of an app—components, modules, or even separate browser contexts (windows, iframes, service workers). Depending on the specific implementation, JSMS may focus on in-memory event buses, networked message passing, or bridging between JavaScript and other systems.

    Common goals of JSMS-like systems:

    • Decouple sender and receiver to improve modularity.
    • Provide a reliable, sometimes persistent way to queue and deliver messages.
    • Support cross-context communication (tabs, workers).
    • Offer simple APIs for publish/subscribe (pub/sub), request/response, or command patterns.

    Why use JSMS?

    • Decoupling: Components can publish events without knowing which parts of the app will handle them. This makes code easier to test and maintain.
    • Scalability: Message-driven architectures allow systems to scale horizontally or to split responsibilities into micro-frontends or microservices.
    • Resilience: Some message systems support retries, persistence, and acknowledgement, improving robustness.
    • Cross-context communication: Useful for coordinating between main threads and web workers, or between tabs and service workers.

    Typical use cases

    • Component communication in single-page applications (SPAs).
    • Integrating background workers (e.g., web workers or service workers) with the UI.
    • Building real-time features (chat, notifications) when combined with network transports.
    • Implementing undo/redo or command stacks by capturing actions as messages.
    • Orchestrating micro-frontends or modular plugins.

    Common patterns and concepts

    • Publisher / Subscriber (Pub/Sub): Publishers emit messages to a channel; subscribers listen on that channel.
    • Event Bus: A centralized dispatcher for events across the application.
    • Request/Response: One component sends a request message and expects a reply.
    • Channels / Topics: Logical namespacing for message flows.
    • Middleware / Filters: Interceptors that can modify, block, or enrich messages before they reach handlers.
    • Acknowledgements & Retries: Mechanisms to confirm delivery and re-attempt failed deliveries.

    Installing and setting up (example)

    The exact installation process depends on the JSMS implementation you choose. Many JSMS-like libraries are available via npm; for example:

    npm install jsms

    (If no npm package exists for your particular JSMS, you might include it via a script tag or clone a repo and build locally.)

    Basic setup pattern (pseudo-code):

    import JSMS from 'jsms'; const bus = new JSMS(); // Subscribe const unsubscribe = bus.subscribe('chat.message', (msg) => {   console.log('Received chat message:', msg); }); // Publish bus.publish('chat.message', { from: 'Alice', text: 'Hello' }); // Unsubscribe when done unsubscribe();

    Simple example: Pub/Sub in the browser

    Below is a minimal example implementing a lightweight JSMS-style event bus from scratch to illustrate the idea:

    class SimpleBus {   constructor() {     this.topics = new Map();   }   subscribe(topic, handler) {     if (!this.topics.has(topic)) this.topics.set(topic, new Set());     this.topics.get(topic).add(handler);     return () => this.topics.get(topic).delete(handler);   }   publish(topic, payload) {     const handlers = this.topics.get(topic);     if (!handlers) return;     for (const h of handlers) {       try {         h(payload);       } catch (err) {         console.error('Handler error for topic', topic, err);       }     }   } } // Usage const bus = new SimpleBus(); const off = bus.subscribe('notify', (p) => console.log('Notify:', p)); bus.publish('notify', { text: 'Welcome!' }); off();

    Example: Communicating with a Web Worker

    JSMS concepts are useful when wiring workers to the main thread:

    main.js

    const worker = new Worker('worker.js'); worker.postMessage({ type: 'task', payload: { n: 10 } }); worker.onmessage = (e) => {   if (e.data.type === 'result') {     console.log('Worker result:', e.data.payload);   } };

    worker.js

    onmessage = (e) => {   if (e.data.type === 'task') {     const n = e.data.payload.n;     // do work...     postMessage({ type: 'result', payload: { value: n * 2 } });   } };

    Wrapping that with a small JSMS layer standardizes message shapes and response handling.

    Best practices

    • Define clear topic names and a naming convention (e.g., domain.event.action).
    • Avoid overusing global buses—limit scope where possible to prevent hidden coupling.
    • Use typed message schemas (TypeScript interfaces or JSON Schema) to validate payloads.
    • Add timeouts and error handling for request/response patterns.
    • Clean up subscriptions to avoid memory leaks.
    • Consider performance: avoid publishing extremely high-frequency messages on a single topic without batching or throttling.

    Pitfalls to watch for

    • Debugging difficulty when too many components publish/subscribe anonymously.
    • Tight coupling through shared message shapes without formal contracts.
    • Memory leaks from forgotten subscriptions.
    • Order-of-delivery assumptions (many simple buses don’t guarantee strict ordering or persistence).
    • Security concerns when messages cross network or untrusted boundaries—always validate and sanitize.

    When to choose JSMS vs alternatives

    If your app needs simple component decoupling, a lightweight in-memory JSMS is effective. For cross-process messaging, persistence, or guaranteed delivery, use a dedicated messaging system (e.g., WebSocket-backed brokers, server-side message queues, or specialized libraries) and connect it to your JSMS abstraction.

    Scenario JSMS (in-memory/event bus) External message broker
    Component decoupling in SPA Good Overkill
    Cross-tab or worker comms OK with adapters Possible with specialized adapters
    Guaranteed, persistent delivery No Yes
    High scale / cross-server No Yes

    Next steps and learning resources

    • Experiment by building a small pub/sub layer in a sample SPA.
    • Try integrating a worker and standardizing messages.
    • Learn TypeScript to add static typing to your messages.
    • Explore libraries and protocols for broader needs (WebSocket, MQTT, Redis Pub/Sub).

    JSMS is best thought of as a pattern and family of tools that help you organize communication within and across JavaScript environments. Start small, keep message contracts explicit, and iterate—messaging can simplify architecture but also add complexity if not disciplined.

  • How KIDO’Z Protects Children Online — Features & Tips

    How KIDO’Z Protects Children Online — Features & TipsKIDO’Z is a child-focused launcher and browser designed to give parents control while offering children a safe, playful environment on smartphones and tablets. It combines filtered content, parental controls, and a curated app ecosystem to reduce exposure to inappropriate material and risky online interactions. Below is a detailed look at how KIDO’Z protects children, its key features, practical setup tips, and limitations parents should know.

    Core protective features

    • Curated content ecosystem: KIDO’Z restricts what children can access by presenting only approved apps, games, videos, and websites in its interface. Instead of exposing kids to the full internet, it functions as a gatekeeper that surfaces age-appropriate content.

    • Built-in content filtering: The app filters web content and blocks categories considered inappropriate for children, such as pornography, gambling, violent or drug-related sites, and adult social media. Filtering reduces accidental exposure to harmful material.

    • App lockdown and whitelisting: Parents can lock the device into KIDO’Z mode and whitelist only specific apps. This prevents children from launching unrestricted apps or the device’s main settings without parental permission.

    • Time limits and schedules: KIDO’Z allows parents to set screen time limits and daily schedules. You can control overall daily usage and create windows when device access is allowed (e.g., homework time, bedtime).

    • Safe search and age-appropriate browsing: The launcher integrates safe search options and offers a family-friendly browsing experience, limiting search results to child-appropriate sites and materials.

    • Customization by age/interest: Content and app recommendations can be customized by age groups or interests, which helps ensure what appears in your child’s interface matches their developmental level.

    • No in-app purchases without permission: KIDO’Z prevents accidental in-app purchases by locking purchase functions or requiring parental confirmation for purchases or downloads, reducing unexpected charges.

    • Simple parental controls interface: The parental dashboard is designed to be user-friendly, enabling parents to review activity, adjust settings, and manage content without technical expertise.

    How it works (technical overview)

    KIDO’Z operates primarily as a launcher on Android devices, replacing the device’s home screen with its own kid-focused interface. From there:

    • The launcher restricts visible apps and content to those approved or installed within KIDO’Z.
    • It uses a combination of curated content libraries and filtering rules for web content.
    • Parental controls are protected by a PIN or password, preventing children from changing settings.
    • Time controls and schedules are enforced locally on the device, and some versions offer remote management via a parent account.

    Step-by-step setup tips

    1. Install and enable:

      • Download KIDO’Z from the Google Play Store.
      • Open the app and follow the on-screen prompts to set it as the default launcher (so kids can’t access the regular home screen).

    2. Create a parental PIN:

      • Choose a strong PIN that your child won’t guess. Note: don’t set easily discoverable numbers like birthdays.

    3. Add child profiles:

      • Create one or more profiles for each child and set age ranges or preferences to tailor content.

    4. Whitelist apps and content:

      • Manually approve apps, games, and websites you want accessible. Remove or restrict access to any apps you don’t want available.

    5. Configure time limits and schedules:

      • Set daily time limits and create schedules for allowed usage (e.g., weekday homework hours blocked, weekend playtimes allowed).

    6. Review privacy and permissions:

      • Check which permissions KIDO’Z requests (access to storage, camera, etc.) and ensure they’re necessary for the child’s experience.

    7. Enable purchase protection:

      • Turn on settings that require parental authentication for downloads or purchases.

    8. Test the child experience:

      • Switch to the child profile and navigate as your child would, verifying content and restrictions work as expected.

    Tips for getting the most protection

    • Combine KIDO’Z with device-level parental controls: Use built-in Android Family Link or iOS Screen Time (on other devices) alongside KIDO’Z for layered protection and broader monitoring features.

    • Keep apps and filter lists updated: Regularly update KIDO’Z and the device OS to benefit from the latest security fixes and content updates.

    • Review activity regularly: Check which apps and videos your child uses most and adjust access or time limits accordingly.

    • Use age-appropriate settings: Be conservative with younger children and gradually expand access as they demonstrate responsibility.

    • Educate your child: Technical controls help, but conversations about online safety, privacy, and behavior are essential. Teach them what to do if they see something upsetting or receive a suspicious message.

    • Supervise new downloads: Approve new apps and test them before allowing regular use.

    Limitations and things to watch for

    • Platform restrictions: KIDO’Z primarily targets Android. Support and effectiveness on other operating systems may be limited.

    • Not a replacement for supervision: Filtering and controls reduce risk but can’t replace active parenting and guidance.

    • Potential bypasses: Determined or tech-savvy children may find ways to exit the launcher or exploit device vulnerabilities; ensure the device’s OS and apps are updated and secure.

    • Varying content coverage: No filter is perfect—some inappropriate content may occasionally slip through or age-appropriate content be blocked erroneously.

    • Privacy considerations: Review KIDO’Z’s privacy policy to understand what data is collected and how it’s used; pair with device privacy settings for better control.

    Alternatives and complementary tools

    Tool Strengths
    Google Family Link Deep device-level control, activity reports
    Apple Screen Time Tight integration on iOS devices
    Qustodio Comprehensive monitoring and web filtering
    Norton Family Strong web filtering and time management

    Use KIDO’Z alongside one of the above if you need richer reporting or cross-device management.

    Final notes

    KIDO’Z provides a straightforward, child-friendly environment that reduces exposure to inappropriate content through curated content, filtering, and parental controls. It’s most effective when combined with device-level controls, regular updates, and ongoing conversations about online safety with your child.
