New discovery. Contrary to the austere and stern W3C spec, if you have a id tag with value “ααα”, it passes W3C validator as valid!. See: W3C HTML Validator Invalid . [2020-08-09 addendum. that's because i was using HTML5 DTD, and HTML5 allows that, but not HTML4]

Google's Defunct Projects: Google Health, Google PowerMeter

[ Google Health ] [ https://en.wikipedia.org/wiki/Google_Health ] (2008 to 2011). This is envisioned to be a centralized health records system, but nobody wants to use it.

[ Google PowerMeter ] [ https://en.wikipedia.org/wiki/Google_PowerMeter ] (2009 to 2011). This is a software that lets you view your energy use. First, you need to install a [ Smart meter ] [ https://en.wikipedia.org/wiki/Smart_meter ]. Then, this is hooked up to Google somehow, so you could view your meter usage on a Google site, with nice charts.

A normal meter just records your usage, and periodically someone comes to check it and bill you. Smart meter differ from normal meter in that it can record hourly usage and communicate that automatically, to the utility company or to you. So, the data can be analyzed and visualized, almost in real-time.

For a in-depth article of Google's closed-down projects, but very much biased and dramatized, see:

When's Google Gonna be as Hateful as Facebook?

Google is really getting on people's nerves in past 2 years.

When someone adds you back, you got this message:

xyz added you back.
She wants to hear from you: start sharing with her and comment on her posts.

Instead of a factual notice, Google gratuitously added “She wants to hear from you”.

I suppose this is part of Search Plus Your World going forcefully down our throats. When is Google Plus gonna become like faaking Facebook?

Dillo Web Browser: Cave-Dwelling Hackers Crawling Out of the Woodwork

Discovered [ Dillo ] [ https://en.wikipedia.org/wiki/Dillo ], a basic browser.


it's funny. Often, in the elite programing community (meaning: not your typical “i code to earn bread” but more of the “i love coding and am superior” hacker types. (the types that slave on slashdot, reddit, hackernews all day.)), you often have a living-in-a-cave phenomenon. You'll often encounter programers crawling out of the woodwork, with obscure and impractical ideas. Dillo is a good example. (other examples are many emacs heads)

let's look at Dillo. So, what is it? Quote from Wikipedia.

Dillo is a minimalistic web browser particularly intended for older or slower computers and embedded systems. It supports only plain HTML/XHTML (with basic CSS rendering) and images over HTTP; scripting is ignored entirely. Dillo is available for Linux, BSD, Solaris, DOS / FreeDOS and Mac OS X. Due to its small size, it is the browser of choice in several space-conscious Linux distributions. Released under the GNU General Public License, Dillo is free software.

that's like a lol. Who will actually find it useful?

this is year 2012. Sure, there are still people on modem and using computers that's 10 years old. But first of all, how many such people exist? probably less than 1/100000 of the internet users.

ok, so if we consider people on modem with old computers, where their computer can't view youtube etc. There's [ text based browsers ] [ https://en.wikipedia.org/wiki/Text_browser ] such as lynx. Also, they could just use any of {Firefox, Chrome, Safari, Opera, IE} with JavaScript turned off. With JavaScript turned off, web browsing is FAST.

of the modem using poor slobs, if they are not tech savvy, they would never know about Dillo or the like anyway, and would never go downloading it even if told so. And if they DO know tech, they'd know how to turn off JavaScript in Firefox, with practical result probably a magnitude better than Dillo.

Blogger Traffic Surge Due to UI Change?

xahlee blogger traffic

I stopped blogging in Jan 28th, and started in Feb 29th, and changed my blogger interface from a static template to blogger's new dynamic template on March 5th.

For reasons unknown to me, my blogger traffic is about 8 times more starting on March 5th.

Is it due to the dynamic UI?
