A compiled template engine for Golang
2013-03-22T00:00:00+00:00
http://sunfmin.com/2013/03/22/a-compiled-template-for-golang
<p>I have asked in <a href="https://groups.google.com/forum/?fromgroups=#!topic/golang-nuts/-wYJik7iL60">go-nuts</a> group that I like to have a template system that compiles to Go code. Here I will describe more about the syntax I think it should work. which I will call it <code>gtemplate</code> for now. There is nothing I have down to implement it yet but just show the idea.</p>
<h2>Package of gtemplate</h2>
<p>A gtemplate package is the same as any go package, It's just a directory inside your <code>GOPATH</code></p>
<p><img src="/images/gtemplate/folder.png" alt="folder" /></p>
<p>The difference for example is along side the generated go source code file <code>hello.go</code>, there is a <code>hello.gt</code> file which is using different syntax but mostly similar to Golang, but gives more convenient for writing template.</p>
<h2>Header part of gtemplate file</h2>
<p><code>hello.gt</code>:</p>
<script src="https://gist.github.com/sunfmin/5219393.js"></script>
<p>You can see that except the func definition, All other part of the .gt file is the same as .go source, this way you can have dependency management for template files the same as go file, and you can put struct definition that will be used for template the same place as the template definition.</p>
<h2>Template func</h2>
<p>You can only define template inside a func, If you write <code>{ {func Hello(d *HelloData)} }</code>, It means the method inside is mainly for output text with fewer variable replacement and loops.</p>
<p>A closer look at the template func definition:</p>
<script src="https://gist.github.com/sunfmin/5219397.js"></script>
<ul>
<li>funcs don't have to use <code>{</code> anymore, It will look ugly if we use <code>{ {</code> to wrap a <code>{</code></li>
<li>The same with all other control statement like <code>if</code>, <code>for</code>, <code>switch</code></li>
<li>function calls are just like normal go code</li>
<li>No return values can be defined in template func, It will be forced to be <code>err error</code></li>
</ul>
<p>What the code looks like that gtemplate generated:</p>
<script src="https://gist.github.com/sunfmin/5219401.js"></script>
<p>It adds an argument <code>w io.Writer</code> to any template func, and write normal template text to the writer.</p>
<p>Every template func automatically added the <code>err error</code> return type.</p>
<p>Template func could be defined on data type as well:</p>
<script src="https://gist.github.com/sunfmin/5219531.js"></script>
<p>So that you can put more commonly used variable as field into your data type.</p>
<p><a href="https://github.com/sunfmin/gtemplate/blob/master/tests/templates/hello.gt">A full gtemplate file</a> and <a href="https://github.com/sunfmin/gtemplate/blob/master/tests/templates/hello.go">A full generated go source code file</a></p>
<h2>What is the workflow for editing gtemplate file</h2>
<p>I am thinking make a tool that watch all your .gt file or config your Editor to generate and compile the .go code whenever you save.</p>
<h2>The benefit I can think of</h2>
<ul>
<li>Compiled template have the same compile sanity check as your go source code, Because the generated go code will be compiled by the same go compiler, So most of template errors could be caught at compile time as well, it will be impossible to write a method call or field that not exist</li>
<li>Pass in as many arguments as you want to a template func call, so it's more flexible then text/template</li>
<li>Compile to go source code make it run as fast as go source code, No reflect used</li>
<li>Package management and distribution for templates the same as go source code, And you can use <code>go get</code> to install your template to the server</li>
<li>The template is compiled along into the binary, So you don't need to copy your template over when deploy your system</li>
<li>Rendering a template can be as easy as calling a go method</li>
<li>Data used by template can be defined together</li>
<li>No need to learn another template language, It's closest to Go syntax</li>
</ul>

http://sunfmin.com/2013/03/19/best-employee-time-tracking-mac-app
<p>Timestamp app is simple and very easy to use app for you to track your time when you are at office or at home, It's a Mac OS X application that depends on Your Apple iCal and Local WIFI network. which is availible by default with any Mac OS X system, It make the time tracking really easy and It needs almost zero user involvement only install the software, Whenever your computer joined your local company WIFI network, It will start an event on Apple iCal and marking the start time, When your computer left the local WIFI network, It will mark the event finish time.</p>
<p>Here is the menu screenshot after it starts up:</p>
<p><img src="/images/timestamp/menu.png" alt="image" /></p>
<p>After you startup, go to the preference settings to add event title and select local WIFI network for recording:</p>
<p><img src="/images/timestamp/preferences.png" alt="image" /></p>
<p>Then you are done, If you careful enough, You will notice that in your Apple iCal, there will be new event already created</p>
<p><img src="/images/timestamp/ical.png" alt="image" /></p>

Open closed company network with ssh out through http proxy
2011-12-12T00:00:00+00:00
http://sunfmin.com/2011/12/12/open-closed-company-network-with-ssh-out-through-http-proxy
<h3>The problem</h3>
<p>You get the situation that company are paranoid that they won't use Amazon EC2 or any other cloud services or rented servers, Because it's not safe to use any others servers except the ones that physically located in their own office. These companies normally their network are closed, computers inside network has to go through a http proxy server to check internet, and they block whatever services they don't like.</p>
<p>And here is the problem, How do you deploy system to the closed server in their office. and update your system frequently to reflect bug fixes and improvements, We know that system can't be perfect just for one release, you have to be continually improve your system with users feedback.</p>
<p>But you can't go into their office to upgrade system for every small fix. It won't be efficient, and not the things we do in this internet age. except the first time after the server ready, you have to go their to configure it initially.</p>
<h3>ssh for the rescue</h3>
<p>How to solve is you make a tunnel to the outside server you have fully control, when you configure their system initially, and keep that tunnel running and create a cron job to check that tunnel process is running and start it if it's gone. Here is how to start a tunnel to other server.</p>
<pre><code>ssh -CnN -R 9999:localhost:22 sasaki@theserver.youhavecontrol.com -p 443
</code></pre>
<ul>
<li>Make sure the sshd service is running at 443 on your outside server, normally company will block other ports then 80, or 443.</li>
<li>-C: Requests compression of all data</li>
<li>-n: Redirects stdin from /dev/null (actually, prevents reading from stdin). This must be used when ssh is run in the background.</li>
<li>-N: Do not execute a remote command. This is useful for just forwarding ports, Don't login to the other server.</li>
<li>-R: do remote port forwarding</li>
</ul>
<p>You can do <code>man ssh</code> to check all the details of these options.</p>
<p>After done this, You can ssh in to theserver.youhavecontrol.com:</p>
<pre><code>ssh sasaki@theserver.youhavecontrol.com -p 443
</code></pre>
<p>Then you ssh into the server inside the company:</p>
<pre><code>ssh username@localhost -p 9999
</code></pre>
<p>What? it doesn't work, the server has to go through http proxy to access internet.</p>
<h3>corkscrew enable you ssh through http proxy</h3>
<p>Go http://www.agroman.net/corkscrew/ to download the latest version of corkscrew:</p>
<pre><code>curl -O http://www.agroman.net/corkscrew/corkscrew-2.0.tar.gz
tar -xzvf corkscrew-2.0.tar.gz
./configure
make && sudo make install
</code></pre>
<p>Then go to ~/.ssh/config</p>
<pre><code>Host *
ProxyCommand /usr/local/bin/corkscrew 10.0.88.88 8080 %h %p
</code></pre>
<p>Note that 10.0.88.88 and 8080 is the companies' http proxy and here is saying any ssh will use corkscrew command and go through that http proxy</p>
<h3>Trouble shooting</h3>
<ol>
<li><p>I have used 80 port at theserver.youhavecontrol.com server, But somehow it doesn't work, and ssh gives these, change to port 443 worked.</p>
