Linux’s local documentation is a useful first stop: `man command` opens a manual, `/keyword` searches within it, and `q` exits. Try `apropos keyword` for broader searches, and check `command --help` before unfamiliar options. #Linux #OpenSource 📷 Photo by César Gaviria on Pexels

🇨🇦 Open Source Week 2027 has its official look! Our new identity is here as preparations continue across Canada. 📅 Aug 29–Sept 4, 2027 📍 Flagship: Prairieland Park, Saskatoon, Sept 3–4 #OpenSourceWeek #OSW2027 #OpenSource

A backup is only useful if you can restore your files. Keep more than one copy, store one separately from your main device, and test restoring a few files. A good routine is one you understand and can maintain. #Linux #OpenSource 📷 Photo by Arina Krasnikova on Pexels

Cloud procurement is also about public control. Ask whether data can be exported, APIs use open standards, providers can be changed, jurisdictions are clear, and the service can be audited or restored. #DigitalSovereignty #OpenStandards

LocalSend is an open-source app for sharing files over your local network. It works across Linux, Windows, macOS, Android and iOS—without email attachments, cloud uploads or an account. Confirm the recipient before accepting a transfer. #OpenSource #LocalSend

🇨🇦 Digital Sovereignty Day Can you leave your software provider? Can you export your data, move it elsewhere or operate the technology independently? If not, who really has control? Digital sovereignty means having choices — and keeping them. #DigitalSovereignty #OpenSource #Linux #Canada

🔐 Cybersecurity Monday SSH is often the front door to your Linux server. 🔑 Use SSH keys 🚫 Disable direct root login 👤 Restrict access 🔄 Keep OpenSSH patched 📋 Check authentication logs Changing port 22 isn't a substitute for proper security. #Linux #Cybersecurity #SSH

Need to find a file without clicking through folders? Try `find ~/Documents -type f -iname '*.pdf'` to search Documents and its subfolders for PDF files, regardless of capitalization. Quote patterns such as '*.pdf' so the shell does not expand them first. 📷 Photo by Jakub Zerdzicki on Pexels

Linux file permissions control who can read, change, or run a file. Use `ls -l` to inspect them: r = read, w = write, x = execute. Grant only the access needed, and be cautious with chmod 777. #Linux #OpenSource 📷 Photo by Tima Miroshnichenko on Pexels

Tesseract OCR can turn many scans into editable, searchable text on Linux. Review names, numbers, tables, and formatting carefully: OCR is a draft. Local processing can help keep sensitive files off online services. #Linux #OpenSource 📷 Photo by Sadi Hockmuller on Pexels

Inkscape is a free, open-source vector editor for diagrams and illustrations. Create a community resource map, then export it as SVG, PDF, or PNG. Keep the editable SVG and check that text is readable at the final size. #OpenSource #Inkscape 📷 Photo by Kevin Williams on Pexels

Federated services let independently operated systems communicate through shared, open protocols. Before adopting one, ask who operates it, what happens if it closes, and whether users can export their information. Open protocols give communities more choic… 📷 Photo by panumas nikhomkhai on Pexels

Terminal Tuesday: `sort -n scores.txt` displays lines in numeric order. Use `-n` because sort treats values as text by default. Save a separate result with `sort -n scores.txt > sorted-scores.txt`. #Linux #TerminalTuesday 📷 Photo by Rafael Minguet Delgado on Pexels

Digital sovereignty also means practical control over information. Open standards can support data export, interoperability, preservation, supplier choice and a realistic migration path. Ask: can another compatible tool use the information? #DigitalSovereignt… 📷 Photo by Sadi Hockmuller on Pexels

OBS Studio is a free, open-source tool for recording your screen, microphone and webcam. For a tutorial, add your display as a source, select your microphone and make a test recording first. Check for private notifications before you begin. #OpenSource #OBSStudio 📷 Photo by John Taran on Pexels

Terminal Tuesday: `wc -l path/to/file` counts lines in a file. Example: `wc -l ~/Documents/meeting-notes.txt` Tip: quote paths with spaces. Line count ≠ paragraph count. #Linux #TerminalTuesday

Before installing a Flatpak, review its permissions. For an installed app: `flatpak info --show-permissions APP_ID` Look for broad access to files, devices or the network. Sandboxing reduces risk, but is not a guarantee. #Linux #Cybersecurity #Flatpak 📷 Photo by Al Nahian on Pexels

A backup is only useful if you can restore from it. Keep three copies of important files, use two types of storage, and keep one copy somewhere separate. Restore a few files occasionally to confirm the backup works. #Linux #OpenSource

Digital sovereignty includes control over your own information. Keep editable documents in ODT or ODS, use CSV for simple tables, and retain the source when exporting a PDF. Could you still use the file if you changed software? #DigitalSovereignty #OpenStandards

Terminal Tuesday: use `du -sh ~/Downloads` to see how much space your Downloads folder uses. Add `--max-depth=1` to see immediate subdirectories. `du` only reports usage, so check paths before cleaning up. #Linux #TerminalTuesday

A fake software update prompt can install malware. Use the app’s built-in updater or the developer’s official website. Unexpected, urgent pop-up? Close it and find official support independently. #CybersecurityMonday #CyberSecurity
