Với hơn 250,000 người sở hữu chứng nhận, LPI là tổ chức chứng nhận Linux và mã nguồn mở đầu tiên và lớn nhất trên thế giới không thuộc về nhà cung cấp nào. LPI đã chứng nhận các chuyên gia tại hơn 180 quốc gia, cung cấp các kỳ thi bằng nhiều ngôn ngữ và có hàng trăm đối tác đào tạo.</p> <p>Sứ mệnh của chúng tôi là thúc đẩy việc sử dụng mã nguồn mở bằng cách hỗ trợ những người làm việc với nó.</p> <p> </p> </div> <div class="footer-social"> <ul class="nav"> <li><a href="https://www.linkedin.com/company/35136" target="_blank" aria-label="linkedin"><i class="fa-brands fa-linkedin-in"></i></span></a></li> <li><a href="https://www.facebook.com/LPIConnect" target="_blank" aria-label="facebook"><i class="fa-brands fa-facebook-f"></i></span></a></li> <li><a href="https://twitter.com/lpiconnect" target="_blank" aria-label="twitter"><i class="fa-brands fa-twitter"></i></span></a></li> <li><a href="https://www.instagram.com/lpi_org/" target="_blank" aria-label="instagram"><i class="fa-brands fa-instagram"></i></span></a></li> <li><a href="https://fosstodon.org/@LPI" target="_blank" aria-label="mastodon"><i class="fa-brands fa-mastodon"></i></span></a></li> </ul> </div> </div> <div class="footer-menu"> <ul id="menu-footer-menu" class="nav"><li id="menu-item-59" class="menu-item menu-item-type-post_type menu-item-object-page menu-item-59"><a href="https://www.lpi.org/vi/ve-lpi/lien-he-chung-toi/"><span>Liên hệ chúng tôi</span></a></li> <li id="menu-item-60" class="menu-item menu-item-type-post_type menu-item-object-page menu-item-60"><a rel="privacy-policy" href="https://www.lpi.org/vi/tuyen-bo-ve-quyen-rieng-tu-va-chinh-sach/"><span>Tuyên bố về Quyền Riêng tư và Chính sách</span></a></li> <li id="menu-item-19770" class="menu-item menu-item-type-post_type menu-item-object-page menu-item-19770"><a href="https://www.lpi.org/vi/quy-tac-dao-duc-va-ung-xu-nghe-nghiep-cua-cong-dong/"><span>Quy tắc Đạo đức và Ứng xử nghề nghiệp của cộng đồng</span></a></li> <li id="menu-item-62" class="menu-item menu-item-type-post_type menu-item-object-page menu-item-62"><a href="https://www.lpi.org/vi/an-hieu/"><span>Thông tin xuất bản</span></a></li> </ul> </div> <div class="footer-copyright"> <p><strong>In case of a content discrepancy between English and the translation, the English version is canonical.<br /> Spot a mistake or want to help improve this translation?
