⚡ HIDDEN SAVINGS

Avatud lähtekood = kiirem jõudlus = suurem kokkuhoid riistvaralt!

Linux annab vanadele arvutitele uue elu — säästes veel ROHKEM raha!

🏎️ Why Linux is FASTER

Windows uses 2–4 GB of RAM just sitting there. Linux uses 400–800 MB. That means your computer has MORE power for YOUR work!

💾

RAM Usage

Windows 11: 3.5 GB idle
Linux Mint: 0.7 GB idle
⚡

Boot Time

Windows 11: 30–60 seconds
Linux: 10–20 sekundit
💽

Disk Space Needed

Windows 11: 64 GB minimum
Linux: 10–20 GB

♻️ Extend Your Hardware Life by 5–10 Years!

Arvuti, mis on „Windowsi jaoks liiga aeglane”, töötab Linuxiga suurepäraselt! Uue arvuti ostmise asemel paigalda Linux ja säästa sadu dollareid.

🖥️

Vana lauaarvuti

10-aastane arvuti, millel on 2GB muutmälu? Paigalda Linux Mint XFCE või Lubuntu — runs like new!

Save $400–$800 on new PC!
💻

Vana sülearvuti

That slow laptop collecting dust? Zorin OS Lite või Peppermint OS brings it back to life!

Save $500–$1,200 on new laptop!
🏫

School Lab (30 PCs)

Instead of buying 30 new PCs at $600 each, install Linux = $18,000 säästetud!

Save $18,000! 🤯
🌱

Help the Planet!

Every reused computer = less e-waste. Linux is green computing — good for your wallet AND the Earth!

Reduce E-Waste! 🌍

⚠️ Did You Know? Windows 11 Killed Millions of Working Computers!

Windows 11 requires TPM 2.0 and 8th-gen Intel CPUs minimum — making perfectly working computers from 2016–2017 "incompatible." These PCs still work great with Linux! Microsoft is pushing people to buy new hardware. Linux gives those computers a second life.

🏢 THE BIG PICTURE

See on isiklik kasutus — kujutle ettevõtte mõõtkava!

Everything above is for ONE person. Now multiply it by a whole organization!

💡 Remember: This is just for ONE person!

🤯 Miks apt is a Superpower

Windowsis tähendab 13 rakenduse installimine 13 veebisaidi külastamist, 13 paigaldusprogrammi allalaadimist, üle 50 korra nupul „Next” klõpsamist ja lootust, et ükski neist ei sisalda pahavara ega tööriistaribasid. Kasutades apt on Linux, it's ÜKS kontrollitud ja turvaline käsk, valmis minutitega. This is the power of open-source software management!

🎆 MAJOR EVENTS

Hetked, mis raputasid maailma!

Avatud lähtekood ei arene lihtsalt tasapisi — vahel ilmub see areenile plahvatuslikult!

DeepSeek R1 — The Open Source AI Earthquake!

Chinese AI lab DeepSeek released DeepSeek R1 — an open-source reasoning AI model that matched GPT-4 and Claude in performance tests. It sent shockwaves through Silicon Valley and caused tech stocks to drop billions in a single day!

$6M
Training cost (vs $100M+ for GPT-4)
MIT litsents
Fully open source & free
$1T+
Tehnoloogiaaktsiate väärtuse langus ühe päevaga

Why it matters: DeepSeek proved that open-source AI can compete with the most expensive closed models. You can run it yourself with ollama run deepseek-r1 — for free, on your own computer!

🦙 Meta avaldab Llama 2 avatud lähtekoodiga

Meta avaldas Llama 2 avatud lähtekoodiga — võimsa tehisarumudeli, mida saab tasuta äris kasutada. See käivitas „avatud tehisaru” revolutsiooni ja tõestas, et tehnoloogiahiiglased saavad tipptehnoloogiat maailmaga jagada. 2024. aastal järgnes veel võimsam Llama 3!

August 2022

🎨 Stable Diffusion Goes Open Source

Stability AI released Stable Diffusion — an AI that creates images from text. Unlike DALL-E and Midjourney (closed), anyone could download, run, and modify it. It democratized AI art creation overnight!

🏥 COVID-19: Open Source Saves Lives

During the pandemic, open-source tools tracked the virus (Johns Hopkins dashboard), shared genome data openly (GISAID), and open-source ventilator designs were shared globally. Open collaboration saved thousands of lives.

2024–2025

🤗 Avatud tehisintellektimudelite plahvatuslik kasv!

Llama 3.1, Mistral, Qwen, Gemma 2, DeepSeek R1 — avatud lähtekoodiga tehisarumudelid on nüüd suletud mudelitega võrdsed või neist paremad. Hugging Face majutab 500,000+ tasuta mudelit. Tehisaru tulevik on avatud!

💎 UNIQUE POWERS

Tools & Capabilities That Don't Exist in Closed Source!

Some things can ONLY be done with open-source tools — there's no paid alternative!

🔄

Pandoc — universaalne dokumenditeisendaja

Convert between 40+ formats: Markdown → PDF → Word → HTML → ePub → LaTeX. No closed-source tool can do this. Used by authors, scientists, and publishers worldwide.

⭐ No closed equivalent exists!
📝

Markdown — universaalne kirjutusvorming

Write once, publish everywhere! Markdown is a simple text format that becomes websites, PDFs, presentations, books, and documentation. GitHub, Reddit, Discord all use it. It's the writer's superpower that closed tools can't match.

⭐ Open standard — works everywhere!
📦

apt / Package Managers — Install Anything Instantly

Üks käsk installib ükskõik millise enam kui 60,000 rakendusest — kontrollitult, turvaliselt ja automaatsete uuendustega. Windowsil pole midagi samaväärset. Microsoft proovis wingetiga, kuid see jääb apt-ist aastaid maha!

⭐ Windows can't match this!
🔀

Git — Version Control for Everything

Track every change to every file, collaborate with millions of people, and never lose work. Created by Linus Torvalds. 100+ million developers use it. The backbone of all modern software development.

🌐 Powers ALL of software development
🐧

Virtual Desktops, Tiling, Customization

Linuxi töölauad, nagu KDE ja GNOME, pakuvad kohandamist, millest Windows ja macOS võivad vaid unistada. Mitu töölauda, paanivad aknahaldurid, teemad ja oma klahvikombinatsioonid — tee arvuti tõeliselt ENDA OMAKS.

✨ Unlimited customization!
🤖
