<p>对Sharelatex的升级将带来以下改变：</p>
<h3 id="域名更换">域名更换</h3>
<p>CRA Sharelatex的校内外访问域名将统一更换为 <a class="link" href="https://sharelatex.cra.ac.cn" target="_blank" rel="noopener"
>sharelatex.cra.ac.cn</a> 。原先的旧域名将会自动重定向至新域名。</p>
<h3 id="中央登陆">中央登陆</h3>
<p>sharelatex的账号管理系统将迁移至CRA维护的LDAP中央认证服务。</p>
<p>在升级完成后，新用户需要使用CRA SSO（<a class="link" href="https://sso.cra.ac.cn/realms/cra-service-realm/account/" target="_blank" rel="noopener"
>https://sso.cra.ac.cn/realms/cra-service-realm/account/</a>）进行注册（注册指南请见下方），<strong>现有用户依然可以用sharelatex上的账户密码登录</strong>。注册CRA SSO后，用户可以使用CRA SSO注册时填写的邮箱和密码登陆sharelatex。</p>
<p>如果需要为没有南科大邮箱的同事注册Sharelatex，请将希望注册的邮箱发送至 <code>[email protected]</code>，管理员看到后将会手动帮忙注册。</p>
<p>推荐现有用户在升级后在CRA SSO注册账户，并使用其中的邮箱和密码登陆。<strong>未注册CRA SSO的用户仍然可以通过本地账户和密码登陆</strong>。但重置密码的操作需要通过CRA SSO进行。</p>
<h2 id="其他cra服务的认证迁移计划">其他CRA服务的认证迁移计划</h2>
<p>CRA将于2022年9月起逐步迁移CRA的其他服务使用CRA SSO登陆。在迁移时，我们将会至少提前一周进行通知。</p>

<p>输入用户名（请使用cas id，如11800001/3000001，注册后无法更改），邮箱（学生请使用数字为用户名的邮箱），密码及姓名（姓名请用英文，可随意，但相关姓名会同步显示在sharelatex中），并完成reCAPTCHA后即可注册。</p>

<p>哈利同学来到位于慧园的南方科技大学科学与工程计算中心机房，询问数据存储规模、服务器性能等情况。<del>他随即从服务器的RAID阵列中抽出一块硬盘，仔细阅读上面的文字说明</del>。接着，他询问计算机研究协会的同学，目前发展数据中心遇到哪些困难。计协的同学说，由于慧园聚集了众多计算集群，而网络带宽和电力供应均十分有限，导致服务级别协议较低，长此下去容易抵消这里发展高性能科学计算和开源软件镜像站的优势。哈利说，单台节点服务级别协议较低的问题在包括清华大学在内的每一所世界一流大学中均有存在。但通过巧妙运用热备节点和负载均衡设备，将能在很大程度上减轻节点故障带来的影响。他叮嘱计算机研究协会要加大新型开源软件镜像的支持力度，增加传输通道、提升运行速率、降低运营成本，为华南地区的开源事业持续赋能。</p>

<p>在科学工程计算中心与网络信息中心的支持下，经过近一个月的稳定性测试，南方科技大学开源软件镜像站现已正式开启公网访问。</p>
<p>不论是在校外还是校内，您现在均可以通过 <a class="link" href="https://mirrors.sustech.edu.cn/" target="_blank" rel="noopener"
>https://mirrors.sustech.edu.cn/</a>.访问镜像站。</p>
<p><strong>为节省学校出口带宽，外部访客在访问镜像站时会被限速。限速策略为：单IP最多 3 个并发连接，每个连接传输速度不超过 2000 KB/s。</strong></p>
<p>With the support of the CCSE and the ITS, the open source software mirror of Southern University of Science and Technology is now officially open for public access.</p>
<p>Whether you are off-campus or on-campus, you can now access the mirror site through <a class="link" href="https://mirrors.sustech.edu.cn/" target="_blank" rel="noopener"
>https://mirrors.sustech.edu.cn/</a>.</p>
<p><strong>In order to save external bandwidth of campus, external visitors will be limited in speed when accessing the mirror site. The speed limit policy is: up to 3 concurrent connections, each with a transfer speed of no more than 2000 KB/s.</strong></p>

<h3 id="简介">简介</h3>
<p>套用一下苹果的广告，Your next MirrorS is not MirrorS, it&rsquo;s MirrorZ. 本项目意在将国内主要镜像的信息整合在一个网站上，满足大家的各种寻找开源软件，系统镜像地址的需求。</p>
<p>网站：<a class="link" href="https://mirrorz.org/" target="_blank" rel="noopener"

alt="MirrorZ的关于页面"
></p>
<h3 id="动机">动机</h3>
<p>虽然国内的镜像站较多，但是镜像之间是异构的。这个异构并不是指底层的技术栈不同，而是指给用户呈现的内容有所差异，毕竟各个镜像站的选择不同。</p>
<p>举个例子，有一天群友问为啥 TUNA 的 OpenWrt 镜像中没有 snapshot，我们自然解释了<a class="link" href="https://github.com/tuna/issues/issues/1076" target="_blank" rel="noopener"
>原因</a>，但用户真的就没有镜像可以使用了吗？其实还是有的，我们在 <a class="link" href="https://mirrorz.org/list/openwrt" target="_blank" rel="noopener"
>https://mirrorz.org/list/openwrt</a> 中逐一寻找，可以发现 HIT 的镜像站中就有 <a class="link" href="https://mirrors.hit.edu.cn/openwrt/snapshots/targets/" target="_blank" rel="noopener"
>snapshot 相关镜像</a>。</p>
<p>另一个例子就是，一位 Arch Linux 用户发现他使用的镜像源同步不太行，准备找个更新一点的镜像，除了去 Arch Linux 官网查找（不是所有镜像都有官网显示镜像同步状态），一种办法自然是去各个镜像站查看状态，但一个个翻镜像实在太困难，有一个整合页面该多好，于是 <a class="link" href="https://mirrorz.org/list/archlinux" target="_blank" rel="noopener"
>https://mirrorz.org/list/archlinux</a> 中就有相应状态的显示。</p>
<h3 id="状态">状态</h3>
<p>目前该项目已经基本可用，已经有了国内多个高校镜像的加入（截至2月28日，已加入mirrorZ的教高校镜像站有：清华大学，北京外国语大学，中国科学技术大学，上海交通大学，东莞理工学院，<strong>南方科技大学</strong>，北京交通大学，南京邮电大学，西安交通大学，同济大学，重庆大学，电子科技大学，哈尔滨工业大学，南京大学，华中科技大学，大连东软信息学院，兰州大学）。</p>
<p>该项目还在火热开发中，更多功能希望大家提出。</p>
<p>mirrorZ更推出「命令行一键换各种源和镜像站测速的脚本」，名为 oh-my-mirrorz，其想法来自 <a class="link" href="http://github.com/tuna/oh-my-tuna" target="_blank" rel="noopener"
>oh-my-tuna</a>，在终端执行<code>curl https://mirrorz.org/oh-my-mirrorz.py | python3</code>即可使用。</p>

<p>Founded by the Center for Science and Computing Engineering(), Computer Research Association to maintain the Southern University of Science and Technology Open Source Software Mirror Station is now officially open to all students and faculty on campus to use! You can access the mirror site through the <strong>domain <a class="link" href="http://mirrors.sustech.edu.cn" target="_blank" rel="noopener"
>mirrors.sustech.edu.cn</a> (http/https) or IP 172.18.6.198</strong>. The mirror site currently provides downloadable images of well-known Linux distributions and open source software such as Ubuntu, Debian, CentOS, Pypi, Anaconda, etc.</p>
<h3 id="survey-on-public-ip-access-and-mirror-requests">Survey on Public IP Access and Mirror Requests</h3>
<p>Currently, the mirror site is only accessible from the campus network. **If you wish to access the mirror from off-campus via the public network, please fill out the questionnaire below and the results will be sent back to the Science and Engineering Computing Center and Information Center for use in the effort to open up public access to the mirror site. **</p>
<p>You can also suggest that the SUSTech mirror site mirror an additional open source project by filling out the survey questionnaire or by creating a new Issue at <a class="link" href="https://github.com/sustech-cra/issues" target="_blank" rel="noopener"

<p>How to build an open source software mirror? How does the software and other content in the mirror site stay in sync? What&rsquo;s the hidden history of SUSTech&rsquo;s open source software mirror? On Sunday of this week, we&rsquo;ll be hosting a workshop on mirror sites, introducing information about open source mirror sites at SUSTech and briefly explaining how to replace the software source with on-campus mirror sources to speed up open source software downloads and updates, everyone is welcomed!</p>

<p>2020 年度中国科学技术大学第七届信息安全大赛即将开幕。中科大信息安全大赛自 2014 年起已经连续举办六届，往届比赛均顺利举行，影响甚广、规模巨大。</p>
<p>本系列比赛自第四届（2017 年）起邀请其他高校的学生来参加，总参加人数在 2000 人左右。</p>
<p>在去年的第六届信息安全大赛中，总共有 2682 人注册，1904 人至少完成了一题。比赛期间所有人合计提交了 17098 次 flag，其中约 57.44% 为正确的提交。题目分为 4 类，包含了综合技能、程序逆向与漏洞利用、密码学与数学和网站安全类题目，在具有一定教育意义的同时也不失趣味性。例如，“献给最好的你”一题结合当时某 Android 病毒应用肆虐的背景，提高了参赛者的安全意识和对不明软件的警惕性；“韭菜银行”一题有关区块链与智能合约的安全性；而“Flag 红包”一题通过流行的“成语接龙红包”的形式，带领选手了解图论、博弈论等算法知识。</p>
<h3 id="时间安排">时间安排</h3>
<p>正式比赛时间：2020 年 10 月 31 日 中午 12:00 ～ 11 月 7 日 中午 12:00 （线上赛）</p>

<p>[The English version is in the second part of the article.](#Introducing CRA-ShareLaTeX: The Self-hosted Overleaf on Campus)</p>
<p>相信对每一位南科大的同学来说LaTeX都不陌生，在许多工科课程上，你都能听到他的名字。作为一门排版语言，Latex在数学/工程领域应用颇广，但由于Latex的复杂编译程序，中文支持问题和动辄好几G的软件空间，让不少同学望而却步。往往是纸上写好公式，编译好几个小时。</p>
<blockquote>
<p><strong>LaTeX</strong>，是一种基于<a class="link" href="https://zh.wikipedia.org/wiki/TeX" target="_blank" rel="noopener"

>莱斯利·兰伯特</a>在20世纪80年代初期开发，利用这种格式系统的处理，即使用户没有排版和程序设计的知识也可以充分发挥由TEX所提供的强大功能，不必一一亲自去设计或校对，能在几天，甚至几小时内生成很多具有书籍质量的印刷品。对于生成复杂表格和<a class="link" href="https://zh.wikipedia.org/wiki/%e6%95%b0%e5%ad%a6" target="_blank" rel="noopener"
>数学</a>公式，这一点表现得尤为突出。因此它非常适用于生成高印刷质量的<a class="link" href="https://zh.wikipedia.org/wiki/%e7%a7%91%e6%8a%80" target="_blank" rel="noopener"
>科技</a>和<a class="link" href="https://zh.wikipedia.org/wiki/%e6%95%b0%e5%ad%a6" target="_blank" rel="noopener"

</blockquote>
<p>在线LaTeX编辑器<a class="link" href="https://www.overleaf.com/project" target="_blank" rel="noopener"
>Overleaf</a>的出现解决了本地LaTeX的许多问题，它能让写作者直接通过浏览器编辑LaTeX代码，并提供“所见即所得”的即时编译结果。</p>

<p>可惜的是，在学校访问互联网上的Overleaf还是会出现访问缓慢，掉线等连接上的问题。同时，免费版的overleaf也<strong>无法实现多人协作（如下图，能够支持10人协作的账号收费15USD/月）和文档历史记录等对于团队项目至关重要的feature</strong>。</p>
