ephemient | 12 years ago | on: SSH uses four TCP segments for each character you type
Are you thinking of EXTPROC/LINEMODE? There's outstanding patches to bash, telnet, and ssh to support these, which enables local line-editing that works smarter than just local echo.
TIOCPKT_IOCTL(EXTPROC) and TIOCSIG support landed in Linux kernel 2.6.36: https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux....

My workaround is to click an element, then type into console
$0.appendChild(document.createElement('tagName'))

Android WebKit and Chrome use V8.

Browser's gone from the stock image on the Nexus 4, 7, and 10.
android.webkit.WebView is still the same Android WebKit engine that Browser used (whether it's installed or not); Chrome brings along its own WebKit port.

I don't know if there are many clients that support it yet, though.

Not true. Internet Explorer used to work with both NSAPI and ActiveX plugins, until they pulled support for the former.
"""Netscape-style plug-ins are supported in Internet Explorer 5.5 Service Pack 1 (SP1) and earlier, but are not supported in Internet Explorer 5.5 Service Pack 2 (SP2) and Internet Explorer 6.""" -- http://support.microsoft.com/kb/306790

After switching between keyboards with Esc in different places, I've learned to use
Ctrl-[
The only downside is being confused when nothing happens in a browser...

Nope,
<file ./command --args

So that you can do tricks like this:

As far as I know, it's an avoidance for a WebKit bug wherein elements' pixel positions and sizes are simply wrong at non-default zoom levels; see https://bugs.webkit.org/show_bug.cgi?id=60318 and all related.

As said above, it's only Win32 that's broken. NT filenames (e.g. \\?\...) aren't limited by MAX_PATH.

Chrome bundles a PDF renderer. (You won't find it in the open Chromium sources; it's by proprietary license from a third party.)

It's already sandboxed and pretty fast and light-weight, so I'm not sure the Chromium developers would put much work into a replacement.

I'm not sure if you can access its state programmatically, but Android already does detection: the WiFi status icon is green if the system can make a connection to Google's servers, and grey otherwise.
IPv[46] have nothing to do with it. "Captive portal" pages are meant to prevent you from getting to the larger Internet, until you do whatever magic is required to dismiss them.
ephemient | 15 years ago | on: "The worst algorithm in the world?"
I have not profiled the code, but I expect that the Newtonian approximation of sqrt is the slowest part.
It would surprise me if "powers" was a big problem relative to the rest. And no shortcuts: each of [1, b b², b³, b⁴, b⁵, …] (up to n) is used in the binomial expansion.
ephemient | 15 years ago | on: "The worst algorithm in the world?"
Hmm, I screwed up and wrote iterate instead of iterate' where I intended. Not that it really makes a difference.
In any case, the average time to print the first 20 Fibonacci numbers is 0.4157ms with matrix exponentiation and 1.707063s with exact integer math (yes, the units are different) on a T400.
