Diagonal to width, simple fractions. Different aspect ratios

Obviously it is easy to calculate the diagonal of e.g. a sensor from the width and height with Pythagoras.
And a bit more tedious the other way round using the aspect ratio. [*]
But for common aspect ratios it is even simpler, 1+1/n fractions within less than 0.4%

Save and restore positions of windows, WindowsPosSaveNRestore

WindowsPosSaveNRestore is a tool to save the position of windows for later restore

This is primarily useful if you frequently change display configuration, say add/remove external monitor(s) e.g. by docking, or turning a device with autorotate active.

Windows also has the bug that it sometimes cram all open windows (and icons [+]) on the primary screen on sleep.

Easy inexpensive chemical free fix for smelly microfibre cloths

Microfibre cloths are nice, but get sour and smelly, even after a machine wash. (same goes for or any other plastic cloths)

They usually smell fine directly from the machine, but soon after they get wet they stink again…

This is easily fixed by a microwave oven!

Displaying images. Colour management, sRGB and ICC. And when something fails.

Update This post started as description of a problem with displaying some files in FireFox and Chrome, but has been transformed to a more general post about sRGB, ICC, CMS and what happens if the browser gets it wrong…

It all started when I detected that most colours in some web-files got severely distorted when displayed in FireFox and Chrome on my system. Both JPG and PNG files were affected

colourchart_1_2_cmp

If you see the first one of these two squares blue_1 and blue_1_removed_srgb substantially different from the second clear blue, your CMS system have similar issues…
The first one is supposed to be a standard blue, the second is blue LEDs on your monitor only.

PhotoView with Delete&Transfer of matched files, e.g. RAW

This is a plain PhotoViewer with just TWO special function:

The ability to show more EXIF info than most and to delete or transfer matching partner files on request also, according to user defined masks.

E.g. Also handle RAW or cropped variant of a file named with predefined syntax.

PhotoView_Dump

Settings for position, size, splitter positions, last used folders… can be saved in users registry.

Download zip: PhotoView.Zip

This is a ‘work in progress’, so expect bugs might be present, and that things can still change quite a bit. (Last modified 2018-09-30)

Central entry point on batteries

(at least this is my intention on how it should end and be used)

It should give info about batteries, how the phone uses them, and (hopefully) with some good hints to how to get the most out of each battery (Life and Stamina). Many of the hints go for other hardware with Li-Ion batteries as well. Say Laptops, Toothbrushes…..

 

This thread is originated from SonyEricssons Xperia phones.

Summary

On problems with weird drops and raises: Try “Johan’s Trick” below once

The currently best advice I can give for the usage pattern is

Try to charge fully and deplete to about 40-50%bc

Once in a while drain battery deep to get calibration right

Keep phone on desk/in bag, avoid pockets, to keep cool.

Leave phone idle while charging (e.g. while sleeping).

 

Note that the ‘remaining percentage’ you see is an ESTIMATE not a measurement!
