revised Maintain different set of extensions in Chrome, on different PCs
correct the path to "advanced sync settings"

comment Maintain different set of extensions in Chrome, on different PCs
I also turned off "sync settings" on my work PC, so I can sync extensions and settings among several home computers without affecting the work PC.

comment Is it possible to run Chrome with and without web security at the same time?
I don't have a mac, but I heard that it works if you include the --user-data-dir option also: open -n -a /Applications/Chrome.app --user-data-dir="/tmp/chrome_dev_session" --disable-web-security. Please give that a try.

comment Why is checking Windows Update so slow?
"The algorithm is not guaranteed to succeed, meaning that WU is perfectly capable of destroying the OS or even rendering it unbootable. This is entirely understandable" What a load of nonsense.

comment Should I disable swap file if I have lots of RAM or should I move it to a virtual RAM drive?
Even for jobs that seem to require more memory than is available, swapping whole pages in and out is rarely the most efficient way to utilize the memory. Better if the programmer designs the job to use RAM and files efficiently as needed in the first place.

comment Should I disable swap file if I have lots of RAM or should I move it to a virtual RAM drive?
Paging virtual memory is like overconfidence, "Yeah, I can handle this job by myself, no worries!" whereas in fact the computer would take a month of swapping to finish the job and doesn't even know it. If a job works well with serial access it should be using files in the first place. If a job requires rapid random access on a large chunk of RAM (e.g. for an in-memory hash, or for executable code), in no way is it acceptable to be swapping that RAM in and out from disk during the operation. The computer pretends it has infinite RAM, but this is a lie and not a helpful one.

comment Should I disable swap file if I have lots of RAM or should I move it to a virtual RAM drive?
IDK, but virtual memory / swapping / delayed loading certainly massively decreases responsiveness compared to older systems (such as Acorn Archimedes, or even old 8-bit Micros) which did not do this. It's a sorry state of affairs when a modern wordprocessor is less responsive for many operations (when first loading, or swapped out) than an 8-bit 2Mhz machine. Personally I would rather have "out of memory" error any day of the week than swapping to disk and the resultant massively degraded performance. This would encourage programmers not to waste RAM.

comment How do I invert all screen colors on Win7, similar to on MacOS?
An excellent solution. It's even possible to fine tune by the config file for inverse video with low blue light, which is my preference.

comment How to disable Auto-Mute Mode?
@LimitedAtonement I don't know. Perhaps your sound device isn't fully supported by Linux kernel drivers, or perhaps the "auto mute" is done in hardware and can't be overridden in software.

comment Meaningful thumbnails for a Video using FFmpeg
To avoid boring images such as plain black and white: generate more thumbnails than you need, compress them with jpeg, and choose the images with larger file size. This works surprisingly well by itself to get decent thumbnails.

comment Meaningful thumbnails for a Video using FFmpeg
My approach is to generate perhaps a dozen jpeg thumbnails at different times, and choose the one with the largest file size. The largest file tends to be more "complex" and interesting, it would seldom be a blurry image, and it will never be a boring image such as a plain black frame. This approach might not be ideal for you, but perhaps you can use it together with other methods.

comment How can I invert all the display colors in Windows Vista?
@Yaurthek, thanks for your work. I noticed you said your app doesn't work on XP. F.lux and redshift do work on XP, so I guess it is possible to invert the screen on XP also. Here's a relevant link: jonls.dk/2010/09/windows-gamma-adjustments Perhaps you could try that technique with NegativeScreen? There's a demo app here: nirsoft.net/vc/change_screen_brightness.html I wanted to write a shorter demo but my windows build env is broken and I don't have time to fix it right now!
