TL; DR. https://termux.librehat.com is a new Termux packages mirror! Maintained by me, synchronised every six hours, located in the United Kingdom, hosted by Oracle Cloud.
In the full article below, I’ll write up how to set up a Termux mirror (or in general, a Debian packages repository mirror).
(more…)This is by all means, not the first blog post about Termux. It serves as a journal for myself, as well for anyone who’s interested in cross building Qt or Qt-related projects for Termux (which is a native Linux environment for Android) from their x86_64 machines.
We already have @xeffyr who has done a great amount of work on building Qt for Termux. The work I’ve done recently would be 10 times harder, if not for what’s achieved by them already.
If you’re new to cross building for Termux, I recommend you to start with Developer Wiki.
(more…)This is the year 2020, Odroid-U3 is far from a powerful ARM development board in today’s standard, but it is still more than capable! Quad-core ARMv7 CPU and 2GB RAM, which means I can still run some light services and test my toy projects without paying any fees to AWS or Azure. The year 2020 also means that this little device can be powered by the mainline Linux kernel without many troubles (if any)! Better than that, the process is ridiculously straightforward!
In this post, I put together the steps I did to build the Linux kernel using upstream mainline source code natively on Odroid-U3. If you’re interested in cross-building from your x86 machines, you can find plenty of tutorials on that on the Internet.
(more…)Microsoft has been steadily enhancing Visual Studio Code Remote Development. One of the components is VS Code Server, which is also open-source and hosted at GitHub. With VS Code Server, you can use Visual Studio Code in a browser. The usual setup involves a server (a VPS perhaps) that hosts the code server. It turns out that it’s also possible to run them locally on your Android device! Here is how.
(more…)上週有幸到鄰國愛爾蘭的Kilkenny郡參加本年度的NodeConf EU大會。會場選在風景宜人的蹩腳窩郊外，離都柏林機場有一個半小時的車程，不遠，就是estate都不在鎮上，所以每天倒也只能全身心灌注在大會和組織者安排的夜間活動上，倒也是個結交新朋好友的機會。
shadowsocks应该是继各种VPN和GoAgent之后，目前最受欢迎的代理协议了。VPN不灵活，而且能够被防火墙识别特征，能够轻松封锁，GoAgent则面临可用IP越来越少的困境。懒得介绍原项目了，不知道shadowsocks的自己去Google查吧。
libQtShadowsocks就像名字暗示的一样，是一个Library（库），用Qt（C++）写的，实现了shadowsocks的各项功能。
QCA是Qt Cryptographic Architecture的缩写，简而言之就是安全组件（如OpenSSL）的Qt封装，方便Qt程序调用，而不用写一大串C代码。QCA自然是开源的，而且好像是KDE的一个project（反正代码是在KDE的git服务器上）。
时隔四年，QCA总算发布了新版本，虽然是小版本号的变化（2.0.3 -> 2.1.0），但却是非常重要的更新！！！首先支持使用Qt5了，其次使用CMake而不是qmake来管理了。如果不支持Qt5的话，我也不会关心QCA的…………
但是目前主流Linux发行版的官方仓库还是2.0.3版的QCA，而且这次也没有Windows builds下载，只有源码包，好在编译不太麻烦，下面就记录了本次编译的过程（环境：Windows 8.1 x64 Pro, MinGW64 4.9.1 x64, MSYS, Qt 5.3.2 x64 static, OpenSSL 1.0.1j x64 static, CMake 3.1.0）。这次要编译的就是静态链接的QCA，如果你要编译动态链接的QCA，上面的工具链必须也是动态链接的！
今天毕业设计答辩结束了，心情大好，于是回宿舍写下了本文～～（脑洞大开的节奏）
我的毕设项目是开发一个材料微观组织图像的分析软件，说直白点，主要功能就是数晶粒、测晶粒度级别数的，还能测多孔材料的孔隙率，第二相百分比等。软件名称是Computer-Aid Interactive Grain Analyser，简称CAIGA，名字没想太久，随便取的。。。
2015-04-08更新：2.0版全新发布，以下部分描述已过时（本文是写于0.x版时期）
不知道Shadowsocks的Windows用户有多少呢？除了一个简陋的Shadowsocks-go客户端、一个废弃的Shadowsocks-csharp客户端和一个用node实现的Shadowsocks-gui客户端，实在找不到一个Native的图形化客户端。于是自己挖坑来填了（越挖越大……）！
下面开始“推销”我的Shadowsocks-Qt5给各位看官使(tiao)用(keng)了！
