updated: Emacs Lisp Text Processing: find-file vs with-temp-buffer

Updated: Emacs Lisp Text Processing: find-file vs with-temp-buffer.In my previous report, the timing difference is by a factor of 45. That's because i had stuff in my init file. (i have hooks for both find-file and html-mode, and that probably caused the major slowdown.) Now, the factor is actually just about 5.You should still use with-temp-buffer instead of find-file besides speed, because find-file has quite some side effects.Big thanks to Trey Jackson.

Review of Khan Academy by Xah Lee

Image
Perm URL with updates: http://xahlee.org/math/khan_academy_review.htmlSo the other day i looked at Khan Academy. Spent a hour to watch a few videos. I find it fantastic, but also disapppointing. Let me explain. (If you don't know already: Khan Academy is a online educational site, basically just thousands of videos, each about 10 minutes. Website at: khanacademy.org)The BadHere's the disappointing parts:• Basics Only. Of all their courses of various subject areas (e.g. sciences, humanities, etc.), the level offered is about first year of university course. At best 2nd year university course.For example, one of the subject they are known for and have the most number of videos is math. Vast majority of them are highschool level (e.g. fraction arithmetic, highschool algebra, etc.). The most advanced course they offer are: {calculus, linear algebra, differential equations}. This means, if you are a math fan, and you have studied first 2 years of university math, then Khan Academy …

Computer Keyboard Wrist RSI Problems

Image
Keyboard Angle IssuesUlnar deviation = bending the wrist outward to the sides. This is solved by split/ergonomic keyboards where the keys are separated into 2 groups. img srcForearm Pronation = rotating the forarm. This is solved by split/ergonomic keyboards that are curved/tilted. img srcand there's also wrist dorsiflexion, meaning bending up the palm. This happens when you use a thick keyboard that sits on a flat desk and your forearm rests on the desk surface. Especially bad when the keyboard's back legs are propped up. This is solved by typing while your wrist hovers above, which is actually the proper typing posture. It is also solved by putting ~5cm thick book in front of the keyboard, or a front tilt as in Microsoft 4000, or a dipped-in keys as in Kinesis Contoured Keyboard, or set your keyboard in a tray below desk surface.read more: http://xahlee.org/emacs/keyboard_problems.html

emacs keyboard: μTron keyboard

updated the emacs keyboard μTron keyboard.“μTRON Keyboard” img src“μTRON Keyboard”This is a excellent design. The only design issue i found is that it doesn't have dedicated function keys. The function keys are merged with the number keys. However, the other quality design makes up for it. (For why dedicated function is important, see: Function Keys in Computer Keyboard. For why the μTron is a excellent design, see: Keyboard Hardware Design Flaws.)Video Intro & Official Website〈はじめてみようμTRONキーボード〉much more photo and info at: http://xahlee.org/kbd/uTRON_keyboard.htmlErgonomic Keyboards GalleryMore Fancy Ergonomic KeyboardsMicrosoft Natural Ergonomic Keyboard 4000Logitech Wave Keyboard ReviewKinesis Contoured Keyboard

Noam Chomsky on Death of Osama Bin Laden

Regarding the death of Osama Bin Laden, Chomsky stated: “We might ask ourselves how we would be reacting if Iraqi commandos landed at George W. Bush's compound, assassinated him, and dumped his body in the Atlantic. Uncontroversially, his crimes vastly exceed bin Laden's, and he is not a ‘suspect’ but uncontroversially the ‘decider’ who gave the orders to commit the ‘supreme international crime differing only from other war crimes in that it contains within itself the accumulated evil of the whole’ (quoting the Nuremberg Tribunal) for which Nazi criminals were hanged: the hundreds of thousands of deaths, millions of refugees, destruction of much of the country, [and] the bitter sectarian conflict that has now spread to the rest of the region.”[86]From Noam Chomsky.94 Photos of Iraq War ₁The Hawking WASPLeaked Video US Helicopter Killing Videothe Saving of Private LynchA People's History of American Empire by Howard ZinnI Met the Walrus (John Lennon)
