I am not fan o em unit to give sizes to html content. But unfortunately I have to work with other developers sometimes. So, some of those likes to use em unit but they have no idea how the em works. Yes I don’t have idea until today. So I have to learn the calculation of em.
Let me share with you too.
EM is relative unit to the nearest parent font-size. So, if you use EM, it means, parent font size X em value.
```
<div style="font-size: 16px">
I am the normal text
    <span style="font-size: 0.9em">Hey I am smaller text</span>
</div>
`

So, the smaller text's font size is `14.4px` 

Still I do not like em units.

Point-free Programming / Tacit Programming
Bu konuda yeterince ingilizce içerik var zaten. Türkçe olarak açıklarsam fonksiyonu tanımlarken alacağı parametreyi belirtmediğinizde point-free programlama yapıyorsunuz. Buradaki point kelimesi “.” manasında değil. Aksine bolca “.” operatörü ile birleştirme yapılabilmesi için de çok güzel oluyor. Çok nokta görünüyor yani bu tarzda.
```
birekle :: Int -> Int
birekle sayi = sayi + 1
birekle = (+) 1 --pointfree
```
Okunabilirlik konusunda ise “okunabilirlik aşinalıktır” lafına bakarsak bu tarzı benimsediğinizde daha okunabilir bir tarz oluyor.

Zero Knowledge Proof
There is a way to get proof for “thing” without getting any “sensitive” or “private” information from.
Zero Knowledge Proof
BUT for now its to expensive to implement for tiny projects. Calculations requires a lot costs.

There is tool named bgrem for using image models to remove backgrounds
```
pipenv shell
pipenv install bgrem[cli]
bgrem i file.jpg output-file.jpg
```
i argument for specifing input file
s argument runs a server and web-ui on port 5000 to use models.
First usage of model requires download. So it will take a little bit time to complete at first run of model.
