最為強大嘅programming法門

Programming就係體驗佛教空性嘅其中一種法門, 但要用它來體驗空性, programmer必需揭而不捨地向程式嘅本質進發, 呢一種就係最為強大嘅programming法門, 與真理接軌嘅修練方式. read count : 4

IT人嘅朵與Framework guideline

一本由framework作者寫的framework設計手則書,內容由作者的角度講出設計framework的重點,思路同手則,如果要寫一份doc去形容自己出黎嘅framework可以參考下呢本書的鋪排: 第一章 : 什麼是好的framework,作者們由自己嘅經驗去給一個定義今大家知道這一次他的設計會顧及那些方面,包括”設計要簡單”,”整合性強”,”設計一致”,等等。 第二章:principle, 架構設計需知 第三四五六七章:落地嘅架構 IT人嘅朵 呢本書集合哂.net framework嘅猛人,人地講自己嘅介紹時會有以下幾點: 做嘅project用左啲乜野技術,例如有位叫Jan Gray嘅人話自己搞compiler包括左semantics, runtime object model, precompiled headers, PDBs等等技術。而香港IT人係linkedin上面笪朵係唔會講到甘深入,通常係甘二講下個project名就算數。 人地會講清楚係咩team到負責咩野,例如係c# language design team負責xml部份嘅parser設計,而香港人笪朵會話係咩team帶緊幾多百人,間公司好幾global,係啲乜乜實實IT協會嘅人,睇完根本都唔知佢係邊一種技術嘅專家(其實係無) 人地笪朵會有佢個blog條link,香港人有blog? 人地會話係msdn雜誌到做過編輯,香港人就連msdn都唔會睇,哈哈 read count : 6

Autotool太複雜

Autotool太複雜,個人認為它阻礙了system programming的發展應該給斷除。AutoTool由三大組件所構成:autoconf, automake和libtool。Autoconf是由autoconf, autoreconf, autoheader, autoscan, autoupdate, ifnames, autom4te, m4指令所合成,automake由automake和aclocal指令合成,libtool則由libtool, libtoolize, ltdl等指令所構成。它們之間也沒有一個統一個使用標準,就是說你可以自己去判斷用那些指令去構建你的build system,所以學習難度非常之大也不統一。所以根本學唔掂,你可以隨便git一個開源項目試下改一下它的autoconf就會知道。 read count : 3

Assembler嘅HLA邊界

寫Assembly用到Marco就試過N次,之前都係用到點就學到邊,無了解過佢嘅邊界,而家差唔多去到要為自己嘅assembler研發marco,所以要先睇下HLA嘅Marco大約可以做到啲乜。沙田圖書館係有唔少好書。 書中講左句: 啲人係用Assembler嘅Marco有幾勁黎判斷個assembler有幾勁,無錯,啲人確實係甘諗。以下就係關於assembler功能上嘅總結: Compile Time Operators. (E.g. : +-*/, <<, >> =, <>) Operator Precedence and Associativity (E.g. : !, -, div, mod) Compile Time Functions Type conversion Numeric functions Character-Classification functions (E.g. : isAlpha, isDigit, isSpace) String functions Symbol information (E.g. : @size, @define @typeName, @elements, @elementSize) Misc compile time functions (E.g. : @odd,…
