Dynamic Language Runtime (DLR)

“This is a huge step for the team, to be able to run a widely-used framework, such as Django, on a dynamic language running on the .NET Framework”
–http://www.infoq.com/news/2008/03/django-and-ironpython
“We’re initially building four languages on top of the DLR – Python, JavaScript (EcmaScript 3.0), Visual Basic and Ruby”
–http://blogs.msdn.com/hugunin/archive/2007/04/30/a-dynamic-language-runtime-dlr.aspx
Man, this is big.

GWT+AIR, will it happen?

AIR brings all kind of web-tech together onto a universal runtime that runs in most of the platform nowadays. Consider we have Flash, Html, Css, Local-file I/O, Local-graphic accel., offline-online-interoperatibility and we have Eclipse as the IDE.

However AIR’s Html part is consideredly weak, it’s just a webkit browser and that’s all. It doesn’t promise to control the web content and functionality and solve the Ajax problems that we experienced, e.g. history, keyboard, browser compatibility, security, etc. In this point, why not let us introduce the ready & matured solution – GWT – to handle this part?

Change

• “Ruby on Rails is a fantastic MVC-ready framework which is much easier for developer than using PHP.”
• “AIR and Flex approach more Java than Javascript, the main reason is that JS is single-thread only, which is not good for desktop apps.”
• “Leopard has a ready-to-use environment for developer – the Xcode toolset, including Debugger and Organizer.”

Adobe 皇朝 – Flex, AIR and Creative Suite

Adobe 近年來的發展很快，各種新技術的開發己形成一種勢力，己經到了一個很容易令人察覺的階段。我想在此整理一下新的價值觀。首先 ECMAScript(我習慣叫Javascript) 將會是一種橫跨 Adobe 所有產品的語言，也同時是 AJAX 類的 Web apps 的唯一語言。「怎樣保護 Source Code」這問題，將會是我第一個要尋找的答案；我相信已經有 solution。

手機將會是新的戰場。

Setting up CVS pserver for Eclipse in OSX 10.4.8(Tiger)

Recently did a few googling for setting up a CVS repository for Eclipse(actually not really matter what ever the client is..) Here I think I should better write it down for future referencing.1. Create the CVS directorysudo mkdir /usr/local/CVS/sudo cvs -d /usr/local/CVS/ initsudo chmod -R a+rw /usr/local/CVS/ (Here have security issue but I dun really care about it.)2. Deal with xinetdCreate a file /etc/xinetd.d/cvspserver with the following content:service cvspserver{disable = nosocket_type = streamwait = nouser = rootserver = /usr/bin/cvsserver_args = -f --allow-root=/usr/local/CVS pservergroups = yesflags = REUSE}Then restart xinetd.sudo kill -HUP `cat /var/run/xinetd.pid`sudo /System/Library/StartupItems/IPServices/IPServices start3. User accountsCreate password file /usr/local/CVS/CVSROOT/passwd with sudo htpasswd -c passwd [username]4. Setting up EclipseIn Eclipse, config the CVS repository connection :pserver:[username]@127.0.0.1:/usr/local/CVS Done.5. Some extra notespserver connection type is unsave, better use pserverssh2 or extsshBASH Cheat SheetVi Cheat Sheet
