Google shutting down your account

Perm url with updates: http://xahlee.org/js/Google_shut_your_account.htmlWhat Happens If Google Shut Down Your Account?Xah Lee, 2011-03-05Yesterday, Google shut down my account for suspecting “unusual activity” for about 4 hours. On 2011-03-03 from ~4 pm to ~8 pm.I have no idea why. I went to bed at 3pm to take a few hours sleep. I woke around 8pm. When i went to my gmail tab, it requires me to login. (usually i don't have to, because i didn't logout.) After i type my gmail and password, then it says my account has been suspended for “unusual activity”. It provides me a option to type my phone number, so google will send me a message and i can verify that. I was reluctant in giving my phone number. After about 10 min reading about Google help, i did, and things went normal again.I am quite unhappy about this. When i checked my Google blogger stats, i realized that Google had shut down my blogger as well, because the stat were flat in the duration. And, i think this also means …

elisp: new version of get-selection-or-unit

Much improved my code for “get-selection-or-unit”. Also, a “unit-at-cursor” function is created. This is separated out because sometimes you want to get the thing at point, without caring whether there's a text selection. For the code, see: Emacs Lisp: Using thing-at-point.

xah's log: refactoring my .emacs

Spent the past 5 hours refactoring elisp code in my .emacs. Not exactly thrilled. it's the kinda work that has no immediate benefit, but potentially disruptive. The software proverb goes: “if it ain't broken, don't fix it.”. I'd say it's only half complete. But am tired of it at this (point). Actually, about every 4 months in past 4 years i spend several hours refactoring stuff there. (not counting the time adding stuff there) As the functions pile up, more time went into it. As my elisp kungfu increases, more is there to be refactored.well, today, most work done is to replace “thing-at-point” by get-selection-or-unit. But alone the way, saw old code, and can't help to clean it.Though, my strategy towards “.emacs” is still basically “don't bother unless you absolutely have to”. Organize Your “dot emacs” Init File in 5 Minutes.

Google Chrome & Browser War II

Google Chrome is really changing the landscape of what web browser is.In Google Chrome, If you click on a mailto link (e.g. mailto:xah@xahlee.org), it'll popup a window that looks just like a normal email app's compose mail window. The mailto uri scheme has pretty much been dead since mid 2000s, but with this Chrome feature, it might revive.SPDY ProtocolGoogle is quite powerful today. Not only having own browser, OS (Google Chrome OS), mobile OS (Android), and gazillion web services, but invents its own protocols.This is old news, but see SPDY. SPDY is a protocol intended to replace HTTP. The interesting part is that it's not just a proposed protocol, but actually used daily when you use Google Chrome to access Google's websites and services. What this means is that, probably sooner or later, others will adopt. Quote:SPDY is a research proje…

Computer Language Design: String Syntax

For example, suppose your code processes a lot html: mystr = "<link rel=\"stylesheet\" type=\"text/css\" href=\"../xyz.css\">"; Here's a practical example from real emacs lisp code.

To the trained eyes however, no matter what name they are under, one can spot them easily by reading the heavily loaded language, heavily critical to the Chinese Communist Party (CCP) with similar style to the CCP official propaganda in the 1960 era (Well the CCP is much smarter now)A bit of background information about Falun Gong(FLG) front organizations — openly…
