The process involves the browser, your computer’s operating system, your internet service provider, the server where you host the site, and the services running on that server.

𝟭. 𝗬𝗼𝘂 𝘁𝘆𝗽𝗲 𝗵𝘁𝘁𝗽𝘀://𝘀𝗼𝗺𝗲𝘄𝗲𝗯𝘀𝗶𝘁𝗲.𝗰𝗼𝗺/𝗽𝗮𝗴𝗲 𝗶𝗻 𝘆𝗼𝘂𝗿 𝗯𝗿𝗼𝘄𝘀𝗲𝗿 𝗮𝗻𝗱 𝗽𝗿𝗲𝘀𝘀 𝗘𝗻𝘁𝗲𝗿

Here, https:// is a scheme, which tells the browser to make a connection to the server using TLS. somewebsite.com is the domain name of the site and it points to a specific IP address of a server. And /page is a path to the resource you need.

𝟮. 𝗕𝗿𝗼𝘄𝘀𝗲𝗿 𝗹𝗼𝗼𝗸𝘀 𝘂𝗽 𝗜𝗣 𝗮𝗱𝗱𝗿𝗲𝘀𝘀 𝗳𝗼𝗿 𝘁𝗵𝗲 𝗱𝗼𝗺𝗮𝗶𝗻

After you’ve typed the URL into your browser and pressed enter, the browser needs to figure out which server on the Internet to connect to. It must look for the IP address of the server hosting the website using the domain you typed to accomplish that. DNS lookup is used to do this. Here, it determines whether we can locate it in the cache; if not, DNS must search domain name servers from the root to the third level.

𝟯. 𝗕𝗿𝗼𝘄𝘀𝗲𝗿 𝗶𝗻𝗶𝘁𝗶𝗮𝘁𝗲𝘀 𝗧𝗖𝗣 𝗰𝗼𝗻𝗻𝗲𝗰𝘁𝗶𝗼𝗻 𝘄𝗶𝘁𝗵 𝘁𝗵𝗲 𝘀𝗲𝗿𝘃𝗲𝗿

Transmission control protocol, more formally known as TCP, is used throughout the public Internet routing infrastructure to route packets from a client browser request through the router, the Internet service provider, through an internet exchange to switch ISPs or networks, and finally to find the server with the IP address to connect to. This is an inefficient oute to take to get there. Instead, a lot of websites employ a CDN to cache both static and dynamic material closer to the browser.

𝟰. 𝗕𝗿𝗼𝘄𝘀𝗲𝗿 𝘀𝗲𝗻𝗱𝘀 𝘁𝗵𝗲 𝗛𝗧𝗧𝗣 𝗿𝗲𝗾𝘂𝗲𝘀𝘁 𝘁𝗼 𝘁𝗵𝗲 𝘀𝗲𝗿𝘃𝗲𝗿

Now that the browser is connected to the server, it complies with the HTTP(s) protocol’s requirements for communication. To request the contents of the page, the browser first sends an HTTP request to the server. The body, headers, and request line of an HTTP request are all present. The server can determine what the client wants to do using the information in the request line.

𝟱. 𝗦𝗲𝗿𝘃𝗲𝗿 𝗽𝗿𝗼𝗰𝗲𝘀𝘀𝗲𝘀 𝗿𝗲𝗾𝘂𝗲𝘀𝘁 𝗮𝗻𝗱 𝘀𝗲𝗻𝗱𝘀 𝗯𝗮𝗰𝗸 𝗮 𝗿𝗲𝘀𝗽𝗼𝗻𝘀𝗲

The server accepts the request and determines how to handle it depending on the data in the request line, headers, and body. The server receives the material at this URL for the GET /page/ HTTP/1.1 requests, builds the response, and then delivers it back to the client with an HTTP status code.

𝟲. 𝗕𝗿𝗼𝘄𝘀𝗲𝗿 𝗿𝗲𝗻𝗱𝗲𝗿𝘀 𝘁𝗵𝗲 𝗰𝗼𝗻𝘁𝗲𝗻𝘁

The browser examines the response headers for instructions on how to render the resource after receiving the server’s response. The Content-Type header informs the browser that an HTML resource was received in the response body.

Zašto su direktori malih privatnih tvrtki na minimalcu?

Ako ste se pitali zašto si vlasnici tvrtki isplaćuju direktorski minimalac, evo jednostavnog izračuna za osobu 30+ godina iz Zagreba.

7.730 kn bruto 2 = 5.000 kn neto

Ako si poveća plaću, onda to izgleda npr. ovako:
17.261 kn bruto 2 = 10.000 kn neto.

U prijevodu, za dodatni trošak od 9.531 kn dobio je neto plaću 5.000 kn više.

Kada bi taj isti iznos od 9.531 kn isplatio kroz dobit, dobio bi iznos od 7.566 kn, što je 2.566 kn više (na razini godine to je razlika od 30.792 kn, tj. 25% novca više ostane).

Ali što je s mirovinom, pošto se ona računa na isplatu iz plaće?

U opciji kada povećavamo isplatu plaće dodatno uplaćujemo 1.636 kn u I. i II. mirovinski stup zajedno, što kod isplate dobiti nije slučaj.

Kada bismo svaki mjesec tu uštedu na razlici od 2.566 kn ulagali trajnim nalogom u fond S&P 500, na period od 20 godina, uzimajući prosječni godišnji prinos u zadnjih 20 godina sve do danas i inflaciju, dolazimo do iznosa od 1.847.000 kn koji bismo imali nakon tog perioda (iznos koji se može u bilo kojem trenutku unovčiti).

U isto vrijeme ukupna razlika uplaćene mirovine u II stup će biti 97.920 kn, što će se u jako optimisitičnoj opciji povećati na 195.840 kn. I taj iznos se ne može unovčiti tj. postoji puno pravila kako se isplaćuje kroz mirovinu.

How have Icelandic teenagers gone from the biggest drinkers and smokers in Europe to the healthiest in 20 years?

Traditionally, the work had focused on individual behavior change: getting teenagers to abstain from alcohol or drugs.

But the campaign leaders in Iceland believed that the focus on “saying no” missed the big picture… What if drug and alcohol use came to feel abnormal in their world rather than normal?

In the mid-90 s, Icelandic teenagers were among the biggest drinkers and smokers in Europe.

Today, Iceland is top of the European countries where the lifestyle of teenagers (13-year-olds) is the healthiest!

How has this evolution been done?
Icelandic scientists have tried to discover the biochemical process that causes addiction.

Harvey Milkman, American Professor of Psychology, now lecturer at Reykjavik University, has come to the conclusion that choosing the type of alcohol or drug depends on how the human body is used to dealing with stress.

Turned out there are many different chemicals that cause biochemical process in the brain, whose body then becomes dependent.

Scientists then looked for actions that stimulate the same process in the brain.

Selon Milkman: ′′ You may be dependent on tobacco, alcohol, coca-cola, energy drinks and some foods….

We decided to offer teenagers something better.

We found that dance, music, drawing or sport also caused biochemical process in the brain that made everything possible, but was also a harmless solution to stress, and that in terms of emotional effect, these actions should have the same effect on teenagers as stimulants, alcohol or tobacco.

From there we offered them free masterclass programs in any sport or art they would like to study.

Overtime, three times a week, has been specifically funded by the state.

Every teenager was asked to participate in the program for three months… but finally, many of them continued these programs for more than five years. ′′

To solve adolescent nicotine and alcohol dependence problems, authorities also had to amend the law.

Iceland has banned advertising for cigarettes and alcoholic beverages and has created special organizations for parents who, in collaboration with the school, help students solve their psychological problems.

Because of this, Iceland has managed to reduce the number of teenagers for the past 20 years who regularly drink from 48 % to 5 %, and those who smoke 23 % to 3 %.

Icelandic scientists suggest using similar methods in other countries.

The question is: who will allow this to happen?

This will be a huge loss for multinationals. They have no interest in adolescents becoming self-conscious and avoiding the path of dependence on alcohol, cigarettes and human stimulants until they die.

They want users.
