Did you know ? Use spaces if you want to make big money 🙂 Evelina Gabasova today at Codemotion took this data and digged deeper showing the audience how data analysis works and why correlation does not necessarily imply causation. Interesting read.

When products/business units ignore each other : Samsung phone and Samsung TV
Let’s assume that you have a Samsung S6 phone and a Samsung TV and that you use videostream for example to see your pc videos on the tv. So since you want to change your tv source to use chromecast you download the samsung tv remote app (which could have been already installed on a samsung phone) so that you can do everything from your phone, select country and language, wait 10 minutes of download of you have no idea what and in the end …. no tv source change in the samsung tv remote app. But you can see the whole tv product set, ranging from 90″ curved screen to anything else … but no tv source change control …
Videostream guys, please put in your app a universal tv remote feature so that all operations on tv can be done from within the videostream app.
Forecasting increase in electricity needs by introducing electric traction in automobile
A growth in electric vehicles on European roads will need a corresponding growth in electricity production to serve charging of these cars, both in peak production power and in total annual power. Let’s take italy for example which currently has a total year consumption of around 300 TWh (terna). Considering :
- Charging efficency (tesla) : 0.85 %
- KWh/km (tesla model x) : 0.1875
- Average Km/year : 10200
This accounts for 2250 KWh/year for each electric car. Considering 2 milion new cars per year and a 0.5 % of electric cars sold (10000) this means an additional 22 GWh/year to be produced to allow charging them.
So your electric car will consume like a small household (depending on your mileage) and personal/distributed production of electricity (domestic + accumulation) will be necessary.

Adda river hydro power plants
During one of my MTB rides at the Cancano lakes I stumbled into this beatifull dam which is part of the A2A Hydro power of Valtellina : 8 hydro power plants from cancano lakes down to Stazzona near Tirano using water coming from the Adda river and from other 4 different basins :
- San Giacomo : 10MW
- Braulio : 19 MW
- Premadio : 226 MW
- Grosio : 428 MW
- Grosotto/Boscaccia : 13 MW
- Lovero 49 MW
- Stazzona : 30 MW
Adda river continues is ride down to Po river and in the mean time produces some other Hydro power in 4 hydro power plants that have been sold to EDF :
- Bertini : 12,5MW
- Taccani : 11 MW
- Semenza : 7 MW
- Esterle : 32 MW
and then into some other small powerplants :
- Rusca : 7 MW
- Italgen Vaprio : 21 MW
- Crespi (Adda Energia) : No data
- Adda S.Anna : No data
- Fara : 1 MW
- Muzza : 2,5 MW
- Maleo : 4,5 MW
- Pizzighettone : 3 MW
A total of around 900 MW of clean, renewable, hydroelectric power!
Google C++ style guide : something every C++ coder out there should read or ““Within C++, there is a much smaller and cleaner language struggling to get out.” — Bjarne Stroustrup”
Having over 100 million lines of C++ code, google took the C++ problem (language with so many features, different ways of doing the same things, dangerous constructs, some pointers to the problems with c++ can be found on wikipedia, and here for an authoritative opinion) seriously and this is what came out.
Some interesting decisions taken :
“We do not use C++ exceptions.” from here
“Avoid defining macros, especially in headers; prefer inline functions, enums, and const variables. Name macros with a project-specific prefix. Do not use macros to define pieces of a C++ API.” from here.
“Avoid complicated template programming” from here
“Within C++, there is a much smaller and cleaner language struggling to get out.” — Bjarne Stroustrup
