Lemon battery...

One of my wildest dreams was to build lemon or potato battery to power Raspberry Pi...

I always thought that it should be easy.

~14 years ago on some industrial fair one of companies was showing some small device powered by potato battery, so I thought that this should work with Rasbperry Pi too.

Problem is that according to science (or at least Wikipedia ;-)) lemon battery build from 1 lemon gives up to 1 mA of current...
And according to this site minimal current needed for RPi vary from 80 mA up to 1250 mA...

So it seems that I would need at least 80 lemons only to power RPi....

It doesn't look as viable plan ;-)

And it also seems that this company I remember wasn't showing working device ;-)
They would much more energy to power device, especially that this was some device connected to GSM modem ;-)

2+ years without a car

Little more than 2 years ago I have collision on highway, and my car transformed from nice but old to simple old ;-)
I tried to repair it, but after spending 1/3 of its price at the time on repairs I got something doesn’t worth of trust.
As a result of this I stopped to drive, and latter throw out a car.

And now I’m more than 2 years without a car.

And to be honest I don’t fell a pain.

Living in city center has its advantages. Everything is soo close that you may go by foot, or in worst case by mass transport, or bike.
In less than 15 minutes on foot I’m able to reach almost all needed places.
Thanks to on-line shoping I don’t need to visit grocery store for big shoping. I simply order on-line, and for smaller things I have shope in the same building I live ;-)

But sometimes I’m thinking about buying a car...
Mainly because I’m used to have a car.
But to be honest I don’t need one.

At least for now.

And looking on prices, I’m not sure if I want to spend half of my yearly wages on something what I will use maybe twice a month.

After a while of thinking - for me biggest advantage of car would be this what it would occupy my parking spot and I would not need to check ocasionally if somebody isn’t using it without my permission ;-)

Experiment.... will try to not complain by next 21 days....

I'm reading Tools of Titans* and in one of interviews Tim Ferris mentioned 21 Day Non Complaint Experiment.
So I'm trying to perform it on myself ;-)

I started with key-leash wrapped around my left wrist.
We will see how it will work ;-)

* - to be honest chapter about psychodelic was little bit scary, I can understand that psychodelics with proper psychological help may do wonders for people with terminal conditions, and cause that they will not be afraid, but I'm still scared when I think about using any narcotics or similar things. Even when I decided that if I will have legal possibility I will try weed (not look for trying but if it will be easy I may try)

I'm close to decide to abandon Linux.....

I'm using Linux on my private computer by last 4 years.
It was good time.

But to be honest I'm starting to think that my next computer will not be with Linux.


Linux is great.
I'm using daily Ubuntu, now in 16.04 version.

I love command line and keyboard shortcuts.

So why I'm thinking about change?

Because of software. Lack of it and not the best quality of it.

I would like to use SourceTree to work with HG and GIT. I know I may use command line, but I would prefer to use SourceTree.
On Windows and macOS it is possible, on Linux not.

I would like to have video drivers working nice with software, and not to have broken vsync in YouTube videos.

When I'm using InteliJ I would like to see nice fonts.

I love Unity on Ubuntu. But Canonical stopped to love it ;-) and 18.04 will not have Unity.
Yeah, probably somebody will make unofficial packages with this. But those will be unofficial.

So, I think that I will need to abandon Linux as desktop OS...

I'm still not sure if I will do it, but I'm starting to think about it.

Earlier I was thinking about buying ultrabook or something similar and using it alongside my "desktop" laptop running Ubuntu, but now I'm thinking about replacing my desktop Linux with something else.

In theory I need to choose from Windows or macOS.

But to be honest, I don't like Microsoft software.
I know that Windows run on a lot of machines, I love some software on Windows like Total Commander and IrfanView, but I don't trust MS.
Mainly because of Windows 8.

So I will probably go with macOS....

Don't like this idea, but at least they still have quiet good command line, nice fonts, a lot of Software, and usually don't abandon solutions...

But even thinking about moving to macOS on my private desktop, I will hope that maybe Google will decide to go to desktop OSes ;-) [No, they will not, but I may hope ;-)]

Android vs iOS

Several days ago I bought iPad Pro 12.9
It's really cool device.

But it isn't ideal.
Biggest problem is iOS.

Now I'm on my old Pixel C, and if I will navigate from Pocket to Chrome and to Maps I simply need to use back navigation button in Android.
I just have similar journey on iOS and going back to Pocket wasn't so easy. I needed to lift whole iPad (which was resting on my belly), find Home button and click it twice times to go to screen showing last apps and to chose Pocket from there.
It's not nice.
It's shows that roots of iOS are in times when only one app was running.

Of course iOS isn't bad in all aspects.
For example they have much better done working with multiple apps on one screen.

But again launcher in iOS is less friendly.
To move app from one screen to another I need to use this "docker" line.

But again iOS wins when we talk about software.
It's maybe less consistent, but generally is nicer and more useful. And more popular. For sure in Android world I will be able to find something similar to Pythonista app, but Pythonista is very well known and installing it I now that a lot of people checked it.

Google+ is much nicer on Android than on iOS. Especially if we compare tablet versions.

Alexa... What to do with her?

Being in US I bought Alexa...
Exactly Amazon Dot.
Partly because I was always interested in this how she works, partly because my friend works in Amazon and she is working somewhere nearby Alexa ;-)
Problem is in this that daily I'm using Google Assistant in Google Home.
I'm very content user of Google Assistant. I'm using it to listen music, set timers, set alarms, get knowledge about weather, time in world and to control my hue lights.
I even created my own action which says me about air quality.

In theory Alexa is able to do most of those things too, but she is worse than Google Assistant on it...

So now I'm thinking about moving her to my bathroom ;-) when I'm taking shower I sometimes need to know time and asking seems to be most natural way.
I have only one Home, which covers my living room, so maybe Alexa will handle this? ;-)
But from other side it doesn't seem ok....
