  • Print Multiple Web Pages Quickly — Top Methods for Chrome, Edge & Firefox


    Why print multiple web pages at once?

    Printing pages one-by-one is slow and error-prone. Batch printing helps you:

    • Save time by processing many pages in one operation.
    • Ensure consistency by using the same print settings across pages.
    • Simplify archiving when saving multiple pages as PDFs.

    Preparatory steps (applies to all browsers)

    Before batch-printing, do the following:

    • Gather the list of URLs to print (plain text, spreadsheet, or bookmarks).
    • Check page layout and remove clutter if necessary (use “Reader View” where available).
    • Decide on output: physical paper or PDF. If PDF, choose a location and filename pattern.
    • Ensure your printer or virtual PDF printer is installed and has enough resources (paper, disk space).

    Methods for Chrome

    1) Open tabs + Print each tab quickly

    This is the simplest approach when you have a limited number of pages.

    • Open all desired pages in separate tabs (shift-click bookmarks or use a bookmark folder → Open all).
    • Right-click a tab and choose “Print…” or press Ctrl+P (Cmd+P on macOS) on each tab and print.
      Tip: Use a virtual PDF printer to “print” all tabs to individual PDFs quickly.

    Pros: No extensions required.
    Cons: Manual per-tab action if many tabs.

    2) Use a Chrome extension: “Print Friendly & PDF” or batch-print extensions

    Several extensions can batch-print or convert multiple pages to PDFs. Common types:

    • Extensions that accept a list of URLs and create a single combined PDF.
    • Extensions that open each URL and send it to the print dialog automatically.

    How to use:

    • Install chosen extension from Chrome Web Store.
    • Provide the list of URLs or select open tabs.
    • Choose page size, margins, header/footer options, then start batch printing.

    Pros: Automated flow, combined PDFs possible.
    Cons: Extensions may have privacy or cost considerations; check permissions.

    3) Save all tabs as PDFs using the Print dialog and a script

    For many tabs, use a small script (e.g., a Chrome extension or bookmarklet) to open each URL, invoke print-to-PDF, and save. This is more advanced and may require extra tools like Selenium or Puppeteer for full automation.


    Methods for Microsoft Edge

    Edge shares many features with Chrome (both are Chromium-based), so all Chrome methods apply. Additionally:

    1) Collections + Print

    • Add pages to a Collection.
    • Open the Collection, right-click entries to open multiple items in tabs.
    • Use Ctrl+P per tab or an extension for batch processing.

    2) Use built-in “Send to OneNote” / “Print to PDF”

    • Edge can send pages directly to OneNote or print to PDF. Use a loop with open tabs to export pages as PDFs one by one, then merge if desired.

    Methods for Firefox

    Firefox differs from Chromium browsers but still supports multiple approaches.

    1) Open tabs + native print

    • Open all pages in tabs (Bookmarks menu → Open All in Tabs).
    • Use Ctrl+P on each tab. Firefox prints using the system print dialog; select “Microsoft Print to PDF” or another virtual printer to save PDFs.

    2) Use Reader View for cleaner prints

    • For cluttered pages, enable Reader View (icon at the address bar) before printing. Reader View removes ads and layout noise and creates cleaner PDFs.

    3) Extensions and add-ons

    • Add-ons like “Print Multiple Tabs” or “Save All Tabs as PDF” can batch-print or save tabs to PDFs. Install from Mozilla Add-ons, provide the list or select tabs, and run.

    Cross-browser automation (advanced)

    For large batches or scheduled jobs, use automation tools:

    • Puppeteer (Node.js) — controls Chromium/Chrome, can render pages and save each as PDF programmatically.
    • Playwright — supports Chromium, Firefox, and WebKit; good for cross-browser PDF generation.
    • Selenium — browser automation for many workflows, including printing via virtual printers or saving page content.

    Example Puppeteer snippet (Node.js) to save multiple pages as PDFs:

    const puppeteer = require('puppeteer'); (async () => {   const browser = await puppeteer.launch();   const urls = ['https://example.com','https://example.org']; // add URLs   for (let i = 0; i < urls.length; i++) {     const page = await browser.newPage();     await page.goto(urls[i], {waitUntil: 'networkidle2'});     await page.pdf({path: `page-${i+1}.pdf`, format: 'A4'});     await page.close();   }   await browser.close(); })(); 

    This approach produces consistent PDFs without manual print dialogs.


    Tips for consistent results

    • Use “Print Preview” to confirm margins, page breaks, and headers/footers.
    • Turn off background graphics if not needed (saves ink and reduces file size).
    • For multi-page articles, set scaling or select “Shrink to fit” to avoid content cutoff.
    • Consider converting to “Reader View” before printing for articles.
    • If merging PDFs, use tools like PDFtk, Adobe Acrobat, or free utilities (many OSes have built-in PDF merging).

    Troubleshooting common issues

    • Missing images or styles: ensure pages fully load before printing (use “networkidle” in automation).
    • Authentication-required pages: automation scripts must handle logins or session cookies.
    • Printer dialog blocking automation: use headless printing to PDF with Puppeteer/Playwright to avoid dialogs.

    Quick comparison

    Method Best for Requires
    Open tabs + manual print Small batches No extra tools
    Browser extension Medium batches, convenience Extension permissions
    Puppeteer/Playwright Large batches, automation Coding knowledge
    Reader View Cleaner article prints Supported pages only

    Final notes

    For occasional needs, opening multiple tabs and printing to a PDF printer is often fastest. For recurring or large-scale jobs, use automation with Puppeteer or Playwright to produce uniform PDFs and avoid manual clicks. Adjust print settings and use Reader View where appropriate to get clean, readable outputs.

  • Hide IP NG: The Complete Beginner’s Guide


    Why hide your IP address?

    Your IP address reveals general location, ISP, and can be used to track browsing across sites. Hiding it can:

    • Improve privacy by reducing tracking and profiling.
    • Help access geo-restricted content.
    • Add a layer of security on public Wi‑Fi.
    • Avoid certain local censorship or IP-based blocking.

    Note: Hiding your IP doesn’t make you anonymous or immune to all forms of tracking (cookies, browser fingerprinting, login accounts, etc.). Combine IP-masking with other privacy practices for stronger protection.


    Common methods to hide your IP

    VPN (Virtual Private Network)

    A VPN routes your traffic through a remote server, replacing your public IP with the server’s IP and encrypting traffic between you and the VPN server.

    Pros:

    • Strong encryption, easy to use, works system-wide.
    • Large selection of server locations.

    Cons:

    • Can slow connection depending on distance/server load.
    • Requires trust in VPN provider.

    When to use: General privacy, streaming geo-unblocking, secure public Wi‑Fi.

    Proxy servers

    A proxy forwards your requests through another server. Types include HTTP(S) proxies, SOCKS5, and web-based proxies.

    Pros:

    • Lightweight, sometimes faster for simple browsing.
    • Useful for single-application routing.

    Cons:

    • Most proxies don’t encrypt traffic.
    • Less privacy than VPNs; some log traffic.

    When to use: Quick IP change for specific apps or browser sessions.

    Tor (The Onion Router)

    Tor routes traffic through multiple volunteer nodes, encrypting data in layers and offering strong anonymity for compatible apps.

    Pros:

    • High anonymity for supported traffic.
    • Harder to trace than single-hop services.

    Cons:

    • Slow for high-bandwidth tasks; many services block Tor exit nodes.
    • Requires careful browser/configuration to avoid fingerprinting.

    When to use: High-anonymity browsing, sensitive research, whistleblowing contexts.

    Smart DNS

    Smart DNS alters DNS responses to make services think you’re in a different location; it doesn’t hide your IP or encrypt traffic.

    Pros:

    • Minimal speed impact; works well for streaming devices.

    Cons:

    • Doesn’t provide privacy or encryption.
    • Only effective for geo-unblocking.

    When to use: Streaming geo-restricted content on devices that don’t support VPN apps.

    Mobile data / tethering / different network

    Switching networks (e.g., from home Wi‑Fi to mobile data) gives you a different public IP assigned by the new network.

    Pros:

    • Simple and immediate.

    Cons:

    • Not a long-term privacy solution; mobile IPs still link to provider.

    When to use: Temporary IP change or testing.


    1. Choose a reputable VPN provider

      • Look for strong encryption (OpenVPN, WireGuard), a clear no-logs policy, multi-country server list, and good performance.
      • Consider paid VPNs for better privacy, performance, and support.
    2. Create an account and download the app

      • Install the official app for your OS (Windows, macOS, Linux, iOS, Android, router).
    3. Configure basics

      • Enable the kill switch (blocks internet if VPN disconnects).
      • Turn on DNS leak protection to ensure DNS queries go through the VPN.
      • Choose a VPN protocol (WireGuard or OpenVPN recommended).
    4. Connect to a server

      • Pick a nearby server for speed or a specific country for geo-access.
      • Verify connection status in the app.
    5. Verify your IP is hidden

      • Visit an IP-check site to confirm the displayed IP and location match the VPN server.
      • Test for DNS leaks using an online DNS leak test.
    6. Optimize settings

      • Enable auto-connect on untrusted networks.
      • Split tunneling: route only specific apps through VPN if supported.
      • Adjust protocol if you need better speed (WireGuard) or compatibility (OpenVPN TCP).

    Step-by-step: Using Tor for better anonymity

    1. Download the Tor Browser from the official site.
    2. Install and launch Tor Browser.
    3. Connect to the Tor network (built into the browser).
    4. Use the browser for privacy-sensitive browsing only; avoid logging into regular accounts.
    5. Follow Tor-specific safety: disable plugins, don’t torrent over Tor, and avoid pasting personal info.

    Step-by-step: Using a proxy (browser example)

    1. Get a reliable proxy (paid SOCKS5 or HTTPS recommended).
    2. Configure browser or app to use proxy host, port, and any credentials.
    3. Test your IP via an IP-check site; remember DNS may still leak unless proxy handles DNS.
    4. Use HTTPS to protect content from eavesdropping.

    Step-by-step: Smart DNS (for streaming)

    1. Subscribe to a Smart DNS provider.
    2. Change DNS settings on your device or router to the provider’s DNS servers.
    3. Some providers require account-based IP registration—add your public IP.
    4. Test streaming services and adjust if needed.

    Practical tips to improve effectiveness

    • Combine tools: use a VPN plus privacy-focused browser and tracker blockers.
    • Clear cookies, use private browsing, or use separate browser profiles for sensitive tasks.
    • Disable WebRTC in browsers to prevent IP leaks over peer-to-peer connections.
    • Use HTTPS-only browsing; non-HTTPS traffic can be observed by intermediaries.
    • Regularly check for DNS, WebRTC, and IPv6 leaks; disable IPv6 if your VPN doesn’t support it.
    • Don’t trust free services implicitly — free VPNs/proxies often log, inject ads, or sell telemetry.

    Troubleshooting common problems

    • Slow speeds: switch to a closer server, use WireGuard, or check for ISP throttling.
    • Connection drops: enable kill switch and auto-reconnect.
    • DNS leaks: enable DNS leak protection or set DNS manually to a privacy-friendly provider (e.g., Cloudflare 1.1.1.1, or another of your choosing).
    • Services blocking VPN/Tor: try different servers, use obfuscated servers, or a residential IP service.
    • Streaming site errors: use servers advertised for streaming, clear cookies, or use Smart DNS.

    • Hiding your IP is legal in most countries but using these tools to commit illegal acts remains illegal.
    • Institutional networks (work/school) may prohibit circumvention; check acceptable-use policies.
    • Trust matters: choose providers with clear privacy policies and minimal logging.

    Quick checklist before you begin

    • Pick a method (VPN recommended).
    • Verify provider reputation and privacy policy.
    • Install official software and enable safety features (kill switch, DNS leak protection).
    • Test IP/DNS/WebRTC for leaks.
    • Combine with browser privacy tools for best results.

    Hiding your IP is an important privacy layer but not a silver bullet. Use it alongside good browser hygiene, strong passwords, two-factor authentication, and cautious sharing of personal data for a more private online presence.

  • How to Choose the Perfect Media Player in 2025

    Lightweight Media Players That Save Battery and SpaceIn an age when devices are expected to do more with less, lightweight media players offer a smart balance: they deliver smooth playback without bloating storage or draining battery life. Whether you’re using an older laptop, a low-powered tablet, or a phone where every percent of battery matters, choosing the right media player can meaningfully improve your experience. This article explains how lightweight media players achieve efficiency, highlights top examples, offers tips to maximize performance, and helps you choose the best player for your needs.


    Why “lightweight” matters

    Lightweight media players focus on minimal resource usage: small disk footprint, low memory consumption, modest CPU usage, and minimal background services. The benefits include:

    • Longer battery life — less CPU/GPU work and fewer background tasks reduce power draw.
    • Faster startup and responsiveness — smaller apps load quickly and respond faster on low-RAM devices.
    • More storage for content — the player itself takes less space, freeing room for media files.
    • Lower thermal strain — reduced processing keeps devices cooler, which helps throttling and longevity.

    How lightweight players save battery and space

    1. Code and feature minimalism

      • Many lightweight players omit heavy UI frameworks, integrated stores, or unnecessary codecs, keeping the installation package small and the runtime footprint low.
    2. Efficient decoding and hardware acceleration

      • By using native, optimized decoders and offloading work to dedicated hardware (GPU/video decoder blocks), players reduce CPU cycles and power use.
    3. Selective background behavior

      • Lightweight apps avoid continuous background services (e.g., media scanning, cloud sync) that otherwise consume CPU/network and battery.
    4. On-demand features

      • Optional plugins or features that load only when needed keep base installs small and efficient.

    Top lightweight media players (examples and highlights)

    Player Key strengths Typical footprint
    MPV Minimal UI, highly efficient, excellent hardware acceleration, scriptable Very small (tens of MB when installed)
    MPC-BE / MPC-HC Lightweight Windows players, low CPU use, simple UI Small installer (~5–10 MB)
    VLC (portable/light mode) Wide format support; can be used with stripped-down builds Larger than ultra-light alternatives but portable builds reduce system impact
    AIMP (for audio) Focused on audio, low CPU use, small install Small (~10–20 MB)
    IINA (macOS, modern MPV front-end) Efficient MPV core with macOS-native UI, supports hardware decoding Moderate—depends on included features

    Practical tips to maximize battery and storage savings

    • Choose players that support hardware-accelerated decoding (e.g., VA-API, VDPAU, DXVA2, VideoToolbox). This reduces CPU usage for H.264/H.265/HEVC streams.
    • Prefer portable versions or minimalist installers when available to avoid unnecessary system-wide components.
    • Disable unused features: auto-updates, background media scanning, cloud sync, and heavy visualizations.
    • Use lower-resolution or lower-bitrate versions of files for mobile viewing when acceptable. Transcode large files to more efficient codecs (H.264, H.265) when device hardware can decode them.
    • Close other high-CPU apps during playback; modern players benefit from dedicated cycles for smoother, more efficient decoding.
    • Use power-saving OS profiles when watching locally (rather than high-performance modes) if smooth playback remains acceptable.
    • Keep codecs and drivers up to date — GPU driver updates often improve hardware decoding efficiency.

    Choosing the best player for your device

    • For very old or low-RAM systems: choose ultra-minimal players like MPV or MPC-HC; avoid feature-heavy suites.
    • For cross-platform needs with good format support: MPV (with a simple GUI front-end) or a portable VLC build balances format compatibility and efficiency.
    • For audio-centric usage: select specialized apps like AIMP or Foobar2000 for minimal overhead and rich audio features.
    • For macOS users who want a native experience: IINA provides a modern UI wrapped around the efficient MPV core.
    • For mobile devices: prefer the system’s native player if it offers hardware acceleration; otherwise use slim apps that explicitly list HW decode support.

    Quick configuration checklist (save battery & space)

    • Enable hardware acceleration in the player settings.
    • Disable background services and auto-update.
    • Use portable or minimal installers.
    • Choose efficient codecs/bitrates for files.
    • Limit visual effects and heavy subtitle rendering when unnecessary.
    • Update GPU drivers and player builds for efficiency fixes.

    Common trade-offs

    Lightweight players often trade convenience features for efficiency. Expect less polished GUIs, fewer built-in streaming plugins, and a leaner feature set. For many users, the battery and storage savings outweigh the missing extras; power users can add selective plugins or scripts to regain needed functionality without bloat.


    Final recommendations

    • If you want the absolute smallest footprint and best efficiency: MPV (with a minimal front-end if you prefer GUIs).
    • If you need a simple Windows-native choice with low overhead: MPC-BE or MPC-HC.
    • For audio-first efficiency: AIMP or Foobar2000.
    • If you need broad compatibility with moderate efficiency and portability: a portable VLC build.

    Pick the player that matches your device constraints and primary use (audio vs. video, local files vs. streaming). Proper settings and opting for hardware decoding will deliver the best battery and space savings with minimal compromise to playback quality.

    4. Load your SNP file via File → Open. If needed, specify a companion sample or annotation file (PED/MAP, sample sheet).
    5. Configure display options (hide/show tracks, set color schemes, adjust windowing) and begin exploring.

    Practical notes:

    • For large VCFs, consider pre-filtering or indexing (tabix) before loading to improve performance.
    • Keep a copy of the portable folder locally if you plan to use custom plugins or settings persistently, as some portable setups reset preferences between sessions.

    Typical workflows and examples

    Example 1 — Quick QC on a genotyping array export:

    • Open the array’s SNP export or VCF.
    • Use the summary pane to check call rates and flag SNPs with high missingness.
    • Filter to SNPs with call rate < 95% or minor allele frequency (MAF) < 1% for inspection.
    • Export a CSV of flagged SNPs for re-analysis.

    Example 2 — Visual inspection of candidate variants:

    • Load a VCF containing variants from a targeted sequencing run.
    • Search by rsID or genomic coordinate for candidate SNPs.

    • Save snapshot images for inclusion in reports.

    Example 3 — Teaching demo:

    • Copy the portable app to a USB key.
    • Prepare a small sample dataset in advance.
    • On the classroom computers, launch the app, load the dataset, and demonstrate filtering, visualization, and exports.

    Tips and best practices

    • Verify input formats: Different genotyping platforms may export subtly different formats; consult the portable app’s documentation for supported schema.
    • Index large VCFs with tabix to enable random access if the app supports it.
    • Keep backups of critical data and exports — portable apps can be accidentally removed or overwritten.
    • Use exported CSVs for downstream scripted analyses rather than relying solely on the GUI.
    • When collaborating, include a small example dataset and brief usage note so colleagues can reproduce your steps without installing software.

    Troubleshooting common issues

    • App won’t start: Check that the portable folder contains all files and that any required runtime (e.g., Visual C++ redistributable) is present on the host machine.
    • Slow on large files: Pre-filter or index the file; try a computer with more RAM or split the dataset into chromosomes.
    • Missing annotations: Ensure annotation/manifest files are in the expected format and path; some portable builds require manual linking to external annotation files.
    • Permission errors on USB: Copy the folder to the local drive and run from there if the host machine restricts execution from removable media.

    Alternatives and complementary tools

    • Genome browsers (IGV, UCSC Genome Browser) for richer genomic context and read-level inspection.
    • PLINK for deeper statistical QC and association testing.
    • bcftools/tabix for command-line filtering and indexing of VCFs.
    • R/Bioconductor packages (SNPRelate, GenomicRanges) for advanced programmatic analyses.

    4. Start decoding; monitor waterfall and decoded message pane for results.
    5. Configure output hooks (log export, HTTP/TCP forwarding, or local scripts) as needed.

    Example minimal command-line for headless decoding on Linux:

    pc-hfdl --input /dev/rtl_sdr --sample-rate 192000 --center-freq 6.8e6 --headless --log /var/log/pc-hfdl.log 

    Troubleshooting Tips

    • Low decode rate: increase input gain carefully, enable AFC, and verify correct sample rate/center frequency.
    • Frequent false decodes: raise detection threshold and reduce noise by filtering input audio or using a narrower SDR filter.
    • Crashes on large log files: enable log rotation and ensure enough disk space; update to latest patch of 635-3.
    • I/Q device not recognized: ensure correct permissions (udev rules on Linux) and confirm device-specific drivers are installed.
    • Time accuracy issues: verify system clock is synchronized (NTP/chrony) because timestamps are derived from system time.

    Security & Privacy Notes

    • Network forwarding can be configured with TLS; ensure credentials and endpoints are secured.
    • Log files may contain aircraft identifiers and message content—treat logs per any applicable regulations or organizational policies.

    Roadmap & Community

    Future planned work (subject to change):

    • Further increases to decode resiliency on very low SNR bursts.
    • GUI enhancements for message threading and grouping.
    • Native packaging for more Linux distributions and ARM performance optimizations.
    • Community plugins for automatic message parsing and visualization.

    Community resources, sample configurations, and contributed scripts are provided in the project repository and documentation. Contributions and bug reports are welcome via the project’s issue tracker.
