To coders the most frequently used tool is their IDE. Well, somebody may say editor! or V.. or Em…. whatever. For me, IDE is the most important thing because it provides design time check.

Let’s overview part of the develop process again: you get design doc from pm or funny/crazy/important ideas pop up in your mind, then you have a general idea on how to implement then code. Sometimes you work with new technology/toolchain/environment, then design time check makes sense. Even if you are expert on the very familiar domain, it helps.

Today several advanced IDE can do something like intelligent check of possible bugs based on context and trying to defer the designer’s purpose. And yes, I mean Visual Studio or Xcode, these kind of resource consuming monsters. They can help you find basic errors like syntax error, spell error, and common errors like off-by-1, uninitialized usage of variables, infinite loop. Then you try compile, compiler gives you compile time check. The code/design again, compile again. These steps iterates until you’ve completed the work then deliver it to test role, tester/qa or yourself if you are building some kinds of tools for fun.

Following this process, if you have many times of switching between code/design and compile, you will mostly lost track if compile takes time…As it has been reported on media or you have realized, you may be distracted on sns/im/twitter/fb. Then after a short time you find that it’s time to go home or have lunch. But even if you are concentrated on your task and working very hard, IDE can help you work in a better way, save your precious time by reducing possibile bugs from the very beginning design time. And you have more confidential if there’s no warning shown when writing plain code or playing elements in UI designers.

                          

[launchOptions valueForKey:UIApplicationLaunchOptionsURLKey]

And for multitask apps, additionally respond to

(BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation // for iOS 4.2+

or

(BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url // for iOS 2.0+, deprecated.

One little trick to handle ALL file types:

	<key>CFBundleDocumentTypes</key>
	<array>
		<dict>
			<key>CFBundleTypeName</key>
			<string>All Files</string>
			<key>LSItemContentTypes</key>
			<array>
				<string>public.data</string>
				<string>public.content</string>
			</array>
		</dict>
	</array>

                          

Well, this post *may* be the last post this year.

                          

Thanks to ipv6, tunnel by he.net.
And datapipe6.c, lol.

As nginx mod_proxy doesn’t support ipv6 upstream, here is the workaround:
datapipe6 localhost 56789 2001:da8:200:900e:200:5efe:a66f:480c 80
And nginx config:

server {
listen 80;
server_name zzxy.feuvan.net;

location / {
proxy_pass http://localhost:56789;
proxy_set_header X-Real-IP $remote_addr;
proxy_cache_valid 10m;
}
location ~* \.(jpg|jpeg|bmp|png|gif|mp3)$ {
proxy_pass http://localhost:56789;
proxy_set_header X-Real-IP $remote_addr;
proxy_cache two;
proxy_cache_key “$scheme$host$request_uri”;
proxy_cache_valid 600m;
}
}

Cernet sux.

If you are blocked to install IE9 preview 4 on server 2008 or R2 (see error msg below), you can use Orca to modify the msi package.

IE9 Preview 4 install blocked on server SKU

You may find Orca.msi on your hard disk “C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\Bin\”.
Or download it, refer to KB255905.

Once Orca is installed, follow the steps to modify the MSI to allow installation on server SKU:

1. Use Orca to open iepreview.msi, Ctrl-F to search string “iepreview_no_server”, you will find it in table “CustomAction” and “InstallExecuteSequence”.
2. Right click on the action and choose “Drop Row” to delete the row in “InstallExecuteSequence”.
3. Save the MSI.
4. Double click to install.

Find iepreview_no_server in Orca

If you would like to know how to find the action “iepreview_no_server” to be deleted, you can try install the original MSI in command line:

msiexec /i iepreview.msi /l*vx ie9p4.log

and analyze the log by yourself. Notice where error occurs.
