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%

This Automower 435X AWD is an upgrade from my 330X, See review here.

The OralB Io 9s does a really good job, and the idea behind the app is great, connecting stinks though, and the case is trash.

The Huawei Band 6 I got (“FRA B19”) is almost identical to the Honor band 6 (see this post) less one important addition.

Got a Honor Watch ES-21C to replace the Honor Band 5 I have had for half a year in October. (And later a Band 6)
(Got it 20201003, this post was last updated 20201224)
An Honor band 6 have emerged after the Watch ES that is in between the two

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.

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!

Here Is a small guide in Disqus-formatting, that I have ‘published’ several times on the old GSMArena.com blog (with tiny variation).

I have written several posts regarding batteries directly and indirectly, especially this old one.
But here I tried to summarise and update it.

This 43″ IPS has substantially better viewing angles used close than its 40″ VA predecessor, but poorer blacks, otherwise much the same.

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
If you see the first one of these two squares and 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.

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.
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)

If you do not want to be a first mover installing Win10, then this link have the recipe to delay it
(A few windows update should be uninstalled if already installed, and then hidden until you want them)
Currently the limitation in the amount of photons that can be caught versus the noise, set a limit for the dynamic range.
But what if the sensor output could not be over saturated?

This Automower 330X is an upgrade from my 230ACX, See review here.

It is rather similar to the 230ACX with some important upgrades, and a few step backs

About two months ago I bought a great monitor
And I do mean great in more than one sense!
The short conclusion is that I can warmly recommend it.

I can HIGHLY recommend this Automower 230ACX, as it have exceeded my expectations.
Overall: Really satisfied. 9+/10
It has handled my highly sloped 1000m² lawn for seven full seasons, with some minor repairs outside the warranty along the way.

(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.
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!
