New tips from Flavio

I wrote a lot about SQL. 6 posts are dedicated to this language we use to interface with powerful databases such as PostgreSQL and MySQL/MariaDB. A few more tutorials will follow next week:
In addition to those SQL tutorials I wrote about when to use let and when to use const in a JavaScript program.

This week, while working on my upcoming JavaScript Full-Stack Bootcamp, I've been working on several technologies including Phaser.js (for JavaScript game programming), Johnny Five (for working with Arduino using JavaScript/Node.js), Redis, WebUSB and more.
The Bootcamp will be fully online and filled with both theory and projects. Lots of them. One cool project I added this week involved creating a Phaser.js platform game, and another project involved using Johnny Five to control the game player using an Arduino with Websockets and WebUSB. It's great to integrate different technologies and make them work smoothly!

[] In this picture the game artwork is very simple and ugly, as I made it myself, but what is important is that I made it from start to finish. Including the simple circuit to connect a joystick component to the Arduino board. And you'll teach you how, in the Bootcamp.
It's coming in a few months, still not sure when exactly but I'll tell keep you updated!
The syllabus of the bootcamp now contains more than 200 modules, each containing multiple lessons, so it will be packed with value.
Finally, let me remind you that I am currently running a special "stay at home" promo for my React, Node, Vue, Svelte and Next.js courses. All at a special 50% discount. Invest your time and learn a new in-demand technology. Check them out.
That's it for this week. See you next Tuesday!

Добијали су сада већ чувену комбинацију антималаријског лека "плакенил" (три пута по 200 милиграма дневно), који садржи супстанцу хидроксихлорокин, и антибиотика "азитромицин", а третман је у просеку трајао 4,9 дана. Студија је показала да је највећи број пацијената, њих 83 одсто, показао брзо смањивање вирусног оптерећења у перидoу краћем од недељу дана, а чак 93 одсто дан касније.

Америчка Агенција за храну и лекове (ФДА) одобрила је коришћење лекова клорокин и хидроксиклорокин у борби против вируса корона, али искључиво у болницама. Лек је намењен само пацијентима који су хоспитализовани. Председник Трамп нахвалио је 24. марта те лекове. И поред одлуке ФДА, лекари строго упозоравају да се лекови, па и ови поменути, не узимају на своју руку.

What is the most unique operating system?

MenuetOS and KolibriOS (Big Russian variant of MenuetOS) is the most unique operating system.
MenuetOS and KolibriOS compiled from FASM assembler.
The third is HaikuOS.
ReactOS is Windows NT like operating system, ReactOS isn’t Linux or Unix.
ReactOS is similar to Microsoft Windows.
JavaOS compiled from Java.
Singularity OS from Microsoft (https://www.microsoft.com/en-us/research/project/singularity/) compiled from Microsoft Visual Studio .NET C#.
Inferno OS/app & Limbo programming language for Inferno OS.

Hrana

Evo liste neke hrane koja će ojačati vaš imuni sistem.
1. Paprika babura
Nisu pomorandže jedina hrana koja će ojačati vaš imuni sistem, a da sadrže vitamin C, nadaleko poznat kao dobar za čuvanje od infekcija. Paprike babure su takođe nosioci, pa čak sadrže i dvaput više vitamina C nego citrusi, što će ojačati vaš imuni sistem.
2. Piletina
Namirnice životinjskog porekla koje sadrže cink, poput piletine, bolje se apsorbuju nego biljne, poput mahunarki. Za žene je dovoljno 8mg, a za muškarce 11mg cinka. Oko 85 grama piletine može da obezbedi oko 2,4 mg cinka, a piletina kao hrana koja će ojačati vaš imuni sistem bi bilo dobro da bude bez kože, da meso bude tanko, a masnoća odstranjena.
3. Pečurke
Vaš imuni sistem najbolje funkcioniše kada ima dovoljno glutationa koji štiti i pomaže ćelijama u imunološkom sistemu. Ovaj moćni antioksidans proizvodi vaše telo, ali s godinama, njegov nivo može pasti. Hrana koja će ojačati vaš imuni sistem i obezbediti ovaj antioksidans jesu upravo pečurke.
4. Spanać
Spanać je na listi hrane koja će ojačati vaš imuni sistem ne samo zato što je bogat vitaminom C, već je i pun antioksidanasa koji povećavaju sposobnost imunog sistema za borbu protiv infekcija. Ali pazite da spanać ne prekuvate, jer se hranjive materije i vitamini lako uništavaju od vrućine.
5. Papaja
Verovatno i ne jedete mnogo papaje, ali možda možete da počnete. Papaja ima 157 odsto dnevne preporuke unosa vitamina C, i kao takva je hrana koja će ojačati vaš imuni sistem. Papaje takođe sadrže i enzim pogodan za varenje koji ima i antiupalne efekte, a uz to i folat, B vitamine i vitamin A. Papaja je i idealni sastojak raznih slatkiša, čime se kombinuje lepo i korisno.
6. Jogurt
Ne samo da je dobar za varenje, jogurt i umanjuje ozbiljnost prehlade i gripa. Istraživanja su pokazala da probiotici u fermentisanoj hrani pomažu da imate jači imuni sistem. Takođe, jogurt sadrži i cink, vitamin A, kalcijum, kalijum i ugljene hidrate da pomognu telu da se oporavi.

More tips from Flavio:

In this special period in time, my React, Node, Vue, Svelte and Next.js courses are currently at a 50% discount. If you find yourself at home and you're looking to invest your time to learn something new that can be beneficial to you in the future, like learning an in-demand skill is, I decided to make this special promo. Check them out.
In the past 2 days I've been having a lot of fun creating simple games in JavaScript using the Phaser library. I made a post on how to set up a Phaser project so I can use a modern workflow with Parcel and browser-sync, and see my changes immediately in a browser window.
I'll be adding a chapter on writing JavaScript games in my upcoming JavaScript Full-Stack Bootcamp, because that's a fun way to learn many of the core concepts of JS.
I'm adding lots of lessons to the bootcamp and I'm refining the syllabus every day. I spent more than 60 hours on it this week, and it's going to take me a few months to complete.
I wrote a module on AWS Lambda and serverless, and I discovered this new unit of measure I hadn't head before: GB-seconds. Turns out it's a way that AWS Lambda uses to figure out how many resources our serverless Node.js functions consume.
Some of the lessons of the bootcamp will be published as blog posts to give you an idea of what's inside. Check this introduction to REST APIs as an example.
I spent a 3 days just talking about Node modules. Here's a list of the Node.js core modules and what they do.
Managing a course with a lot of lessons means changing folder names and ordering a lot. I wrote a command-line script in Node.js to increment folder numbers automatically for me.
Ah, I have a cool story too. I've always been a contractor/freelancer all my working life, but in 2017, I was somewhat tired and got this idea of being hired full time at a company. I started learning Go, just to change things a bit, and I wrote my adventure doing so in this post: my plan for being hired as a Go developer.
That's it for this week. See you next Tuesday!

Novak Djokovic vs Corona Virus

Chloroquine + Zink



Novak Đoković je poznat po zdravom načinu ishrane. On je ekskluzivno na telegraf.rs dao svoje viđenje u vezi Korona virusa i kako bi ljudi trebali da rade da bi pojačali imunitet organizma. Tekst vam prenosimo u celosti.
– Uvećajte unos Vitamina C i Cinka. Preporučeno je između 5 do 7 grama dnevno Vitamina C, a može i do 10. Ukoliko nađete tečni Cink, bolje je nego u drugoj formi. U slučaju da ne nađete tečni Cink, i u pilulama je dobro uzimati 3 do 4 puta veću dozu nego uobičajeno preporučene doze.


Encrypt

//PHP password hash:

$hash = password_hash("CLEAR", PASSWORD_DEFAULT);
$ok = password_verify("CLEAR", "HASHED");

//Openssl encript decript:

$hash = openssl_encript("CLEAR", "AES-128-ECB", "SECRETKEY");
$plain = openssl_decript("HASHED", "AES-128-ECB", "SECRETKEY");

//CRYPT:

$hash = crypt("CLEAR TEXT");
$ok = hash_equals("HASHED", crypt("CLEAR", "HASHED"));


//MD5:

$hash = md5("CLEAR");
$ok = md5("CLEAR") == $hash;
