What Mongolian IT Industry Can Learn from Bulgaria?Svetlin Nakov
In this talk the speaker Dr. Svetlin Nakov explains the growth of the Bulgarian software industry for the latest 25 years and the key events in its growth.
He gives rich statistical data about Bulgaria, its GDP, and its software industry, which generates nearly 5% of the GDP (in 2022), about the open developer positions (5K in Oct 2022) and the number of software developers in Bulgaria (54K in Oct 2022).
The growth of the number of software developers in Bulgaria, software industry's revenues and their share in the national GDP are traced back from 2022 to 2005.
Similar research about the Mongolian software industry is conducted and available data is compared to Bulgaria and USA.
An interesting parallel is given between Bulgaria and Mongolia in terms of their software engineering talent and industry growth potential.
Finally, Dr. Nakov gives his recommendations about how local Mongolian software companies can reach the global tech market and suggests to use the "outstaffing" business model, targeting the European tech industry and the Asian region.
The talk is given at the "The Future of IT" forum in Ulaanbaatar, Mongolia (October 2022).

Providing Globus Services to Users of JASMIN for Environmental Data AnalysisGlobus
JASMIN is the UK’s high-performance data analysis platform for environmental science, operated by STFC on behalf of the UK Natural Environment Research Council (NERC). In addition to its role in hosting the CEDA Archive (NERC’s long-term repository for climate, atmospheric science & Earth observation data in the UK), JASMIN provides a collaborative platform to a community of around 2,000 scientists in the UK and beyond, providing nearly 400 environmental science projects with working space, compute resources and tools to facilitate their work. High-performance data transfer into and out of JASMIN has always been a key feature, with many scientists bringing model outputs from supercomputers elsewhere in the UK, to analyse against observational or other model data in the CEDA Archive. A growing number of JASMIN users are now realising the benefits of using the Globus service to provide reliable and efficient data movement and other tasks in this and other contexts. Further use cases involve long-distance (intercontinental) transfers to and from JASMIN, and collecting results from a mobile atmospheric radar system, pushing data to JASMIN via a lightweight Globus deployment.

How to Position Your Globus Data Portal for Success Ten Good PracticesGlobus
Science gateways allow science and engineering communities to access shared data, software, computing services, and instruments. Science gateways have gained a lot of traction in the last twenty years, as evidenced by projects such as the Science Gateways Community Institute (SGCI) and the Center of Excellence on Science Gateways (SGX3) in the US, The Australian Research Data Commons (ARDC) and its platforms in Australia, and the projects around Virtual Research Environments in Europe. A few mature frameworks have evolved with their different strengths and foci and have been taken up by a larger community such as the Globus Data Portal, Hubzero, Tapis, and Galaxy. However, even when gateways are built on successful frameworks, they continue to face the challenges of ongoing maintenance costs and how to meet the ever-expanding needs of the community they serve with enhanced features. It is not uncommon that gateways with compelling use cases are nonetheless unable to get past the prototype phase and become a full production service, or if they do, they don't survive more than a couple of years. While there is no guaranteed pathway to success, it seems likely that for any gateway there is a need for a strong community and/or solid funding streams to create and sustain its success. With over twenty years of examples to draw from, this presentation goes into detail for ten factors common to successful and enduring gateways that effectively serve as best practices for any new or developing gateway.
Climate Science Flows: Enabling Petabyte-Scale Climate Analysis with the Eart...Globus
The Earth System Grid Federation (ESGF) is a global network of data servers that archives and distributes the planet’s largest collection of Earth system model output for thousands of climate and environmental scientists worldwide. Many of these petabyte-scale data archives are located in proximity to large high-performance computing (HPC) or cloud computing resources, but the primary workflow for data users consists of transferring data, and applying computations on a different system. As a part of the ESGF 2.0 US project (funded by the United States Department of Energy Office of Science), we developed pre-defined data workflows, which can be run on-demand, capable of applying many data reduction and data analysis to the large ESGF data archives, transferring only the resultant analysis (ex. visualizations, smaller data files). In this talk, we will showcase a few of these workflows, highlighting how Globus Flows can be used for petabyte-scale climate analysis.
8. Java – Introduction
Java is modern, flexible, general-purpose
programming language
Object-oriented by nature, statically-typed, compiled
In this course will use Java Development Kit (JDK) 12
Later versions will work as well
9
static void main(String[] args) {
// Source Code
}
Program
entry
point
9. IntelliJ IDEA is powerful IDE for Java and other languages
Create a project
Using IntelliJ Idea
10
10. Declaring Variables
Defining and Initializing variables
Example:
11
{data type / var} {variable name} = {value};
int number = 5;
Data type
Variable name
Variable value
12. Reading from the Console
We can read/write to the console,
using the Scanner class
Import the java.util.Scanner class
Reading input from the console using
13
import java.util.Scanner;
…
Scanner sc = new Scanner(System.in);
String name = sc.nextLine(); Returns String
13. Converting Input from the Console
scanner.nextLine() returns a String
Convert the string to number by parsing:
14
import java.util.Scanner;
…
Scanner sc = new Scanner(System.in);
String name = sc.nextLine();
int age = Integer.parseInt(sc.nextLine());
double salary = Double.parseDouble(sc.nextLine());
14. We can print to the console, using the System class
Writing output to the console:
System.out.print()
System.out.println()
Printing to the Console
15
System.out.print("Name: ");
String name = scanner.nextLine();
System.out.println("Hi, " + name);
// Name: George
// Hi, George
15. Using format to print at the console
Examples:
16
Using Print Format
Placeholder %s stands for string
and corresponds to name
Placeholder %d stands
for integer number and
corresponds to age
String name = "George";
int age = 5;
System.out.printf("Name: %s, Age: %d", name, age);
// Name: George, Age: 5
16. D – format number to certain digits with leading zeros
F – format floating point number with certain digits after the
decimal point
Examples:
int percentage = 55;
double grade = 5.5334;
System.out.printf("%03d", percentage); // 055
System.out.printf("%.2f", grade); // 5.53
Formatting Numbers in Placeholders
17
17. Using String.format to create a string by pattern
Examples:
String name = "George";
int age = 5;
String result = String.format(
"Name: %s, Age: %d", name, age);
System.out.println(result);
// Name: George, Age 5
Using String.format(…)
18
18. You will be given 3 input lines:
Student name, age and average grade
Print the input in the following format:
"Name: {name}, Age: {age}, Grade {grade}"
Format the grade to 2 decimal places
Problem: Student Information
19
John
15
5.40
Name: John, Age: 15, Grade: 5.40
19. import java.util.Scanner;
…
Scanner sc = new Scanner(System.in);
String name = sc.nextLine();
int age = Integer.parseInt(sc.nextLine());
double grade = Double.parseDouble(sc.nextLine());
System.out.printf("Name: %s, Age: %d, Grade: %.2f",
name, age, grade);
Solution: Student Information
20
24. The simplest conditional statement
Test for a condition
Example: Take as an input a grade and check if the student
has passed the exam (grade >= 3.00)
The if Statement
25
double grade = Double.parseDouble(sc.nextLine());
if (grade >= 3.00) {
System.out.println("Passed!");
}
In Java, the opening
bracket stays on the
same line
25. Executes one branch if the condition is true and another,
if it is false
Example: Upgrade the last example, so it prints "Failed!",
if the mark is lower than 3.00:
The if-else Statement
26
The else
keyword stays
on the same
line, after the }
if (grade >= 3.00) {
System.out.println("Passed!");
} else {
// TODO: Print the message
}
26. Write a program that reads hours and minutes from the console
and calculates the time after 30 minutes
The hours and the minutes come on separate lines
Example:
Problem: I Will be Back in 30 Minutes
27
23
59 0:29
1
46 2:16
0
01 0:31
11
32 12:02
11
08 11:38
12
49 13:19
27. Solution: I Will be Back in 30 Minutes (1)
28
int hours = Integer.parseInt(sc.nextLine());
int minutes = Integer.parseInt(sc.nextLine()) + 30;
if (minutes > 59) {
hours += 1;
minutes -= 60;
}
// Continue on the next slide
28. Solution: I Will be Back in 30 Minutes (2)
29
if (hours > 23) {
hours = 0;
}
if (minutes < 10) {
System.out.printf("%d:%02d%n", hours, minutes);
} else {
System.out.printf("%d:%d", hours, minutes);
}
%n goes on
the next line
30. Works as sequence of if-else statements
Example: read input a number and print its corresponding month:
The switch-case Statement
31
int month = Integer.parseInt(sc.nextLine());
switch (month) {
case 1: System.out.println("January"); break;
case 2: System.out.println("February"); break;
// TODO: Add the other cases
default: System.out.println("Error!"); break;
}
31. By given country print its typical language:
English -> England, USA
Spanish -> Spain, Argentina, Mexico
other -> unknown
Problem: Foreign Languages
32
England English
Spain Spanish
32. Solution: Foreign Languages
33
// TODO: Read the input
switch (country) {
case "USA":
case "England": System.out.println("English"); break;
case "Spain":
case "Argentina":
case "Mexico": System.out.println("Spanish"); break;
default: System.out.println("unknown"); break;
}
34. Logical operators give us the ability to write multiple
conditions in one if statement
They return a boolean value and compare boolean values
Logical Operators
35
Operator Notation in Java Example
Logical NOT ! !false -> true
Logical AND && true && false -> false
Logical OR || true || false -> true
35. A theatre has the following ticket prices according to the age of
the visitor and the type of day. If the age is < 0 or > 122,
print "Error!":
Problem: Theatre Promotions
36
Weekday
42
18$ Error!
Day / Age 0 <= age <= 18 18 < age <= 64 64 < age <= 122
Weekday 12$ 18$ 12$
Weekend 15$ 20$ 15$
Holiday 5$ 12$ 10$
Holiday
-12
36. Solution: Theatre Promotions (1)
37
String day = sc.nextLine().toLowerCase();
int age = Integer.parseInt(sc.nextLine());
int price = 0;
if (day.equals("weekday")) {
if ((age >= 0 && age <= 18) || (age > 64 && age <= 122)) {
price = 12;
}
// TODO: Add else statement for the other group
}
// Continue…
37. Solution: Theatre Promotions (2)
38
else if (day.equals("weekend")) {
if ((age >= 0 && age <= 18) || (age > 64 && age <= 122)) {
price = 15;
} else if (age > 18 && age <= 64) {
price = 20;
}
} // Continue…
38. Solution: Theatre Promotions (3)
39
else if (day.equals("holiday")){
if (age >= 0 && age <= 18)
price = 5;
// TODO: Add the statements for the other cases
}
if (age < 0 || age > 122)
System.out.println("Error!");
else
System.out.println(price + "$");
40. A loop is a control statement that repeats
the execution of a block of statements.
Types of loops:
for loop
Execute a code block a fixed number of times
while and do…while
Execute a code block while given condition is true
Loop: Definition
41
42. The for loop executes statements a fixed number of times:
For-Loops
43
Initial value
Loop body
for (int i = 1; i <= 10; i++) {
System.out.println("i = " + i);
}
Increment
Executed at
each iteration
The bracket is
again on the
same line
End value
43. Print the numbers from 1 to 100, that are divisible by 3
You can use "fori" live template in Intellij
Example: Divisible by 3
44
for (int i = 3; i <= 100; i += 3) {
System.out.println(i);
}
Push [Tab] twice
44. Write a program to print the first n odd numbers and their sum
Problem: Sum of Odd Numbers
45
5
1
3
5
7
9
Sum: 25
3
1
3
5
Sum: 9
45. Solution: Sum of Odd Numbers
46
int n = Integer.parseInt(sc.nextLine());
int sum = 0;
for (int i = 1; i <= n; i++) {
System.out.println(2 * i - 1);
sum += 2 * i - 1;
}
System.out.printf("Sum: %d", sum);
47. Executes commands while the condition is true:
int n = 1;
while (n <= 10) {
System.out.println(n);
n++;
}
While Loops
48
Loop body
Condition
Initial value
Increment the counter
48. Print a table holding number*1, number*2, …, number*10
Problem: Multiplication Table
49
int number = Integer.parseInt(sc.nextLine());
int times = 1;
while (times <= 10) {
System.out.printf("%d X %d = %d%n",
number, times, number * times);
times++;
}
50. Like the while loop, but always executes at least once:
int i = 1;
do {
System.out.println(i);
i++;
} while (i <= 10);
Do ... While Loop
51
Loop body
Condition
Initial value
Increment
the counter
51. Upgrade your program and take the initial times from the console
Problem: Multiplication Table 2.0
52
int number = Integer.parseInt(sc.nextLine());
int times = Integer.parseInt(sc.nextLine());
do {
System.out.printf("%d X %d = %d%n",
number, times, number * times);
times++;
} while (times <= 10);
53. The process of debugging application includes:
Spotting an error
Finding the lines of code that cause the error
Fixing the error in the code
Testing to check if the error is gone
and no new errors are introduced
Iterative and continuous process
Debugging the Code

Editor's Notes
Hello, I am Svetlin Nakov from SoftUni (the Software University). Together with my colleague George Georgiev, we shall teach this free Java Foundations course, which covers important concepts from Java programming, such as arrays, lists, methods, strings, classes, objects and exceptions, and prepares you for the "Java Foundations" official exam from Oracle.This lesson aims to review the basic Java syntax, console-based input and output in Java, conditional statements in Java (if-else and switch-case), loops in Java (for loops, while loops and do-while loops) and code debugging in IntelliJ IDEA. Your trainer George will explain and demonstrate all these topics with live coding examples and will give you some hands-on exercises to gain practical experience with the mentioned coding concepts.
Let's start!
Before the start, I would like to introduce your course instructors: Svetlin Nakov and George Georgiev, who are experienced Java developers, senior software engineers and inspirational tech trainers.
They have spent thousands of hours teaching programming and software technologies and are top trainers from SoftUni.
I am sure you will like how they teach programming.
Most of this course will be taught by George Georgiev, who is a senior software engineer with many years of experience with Java, JavaScript and C++.
George enjoys teaching programming very much and is one of the top trainers at the Software University, having delivered over 300 technical training sessions on the topics of data structures and algorithms, Java essentials, Java fundamentals, C++ programming, C# development and many others.
I have no doubt you will benefit greatly from his lessons, as he always does his best to explain the most challenging concepts in a simple and fun way.
Before we dive into the course, I want to show you the SoftUni judge system, where you can get instant feedback for your exercise solutions.
SoftUni Judge is an automated system for code evaluation. You just send your code for a certain coding problem and the system will tell you whether your solution is correct or not and what exactly is missing or wrong.I am sure you will love the judge system, once you start using it!
// Solution to problem "01. Student Information".
import java.util.Scanner;
public class Main {
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
String name = sc.nextLine();
int age = Integer.parseInt(sc.nextLine());
double grade = Double.parseDouble(sc.nextLine());
System.out.printf("Name: %s, Age: %d, Grade: %.2f",
name, age, grade);
}
}
This first lesson aims to briefly go over the material from the Java basics course and revise the key concepts from Java coding. If you have basic experience in another programming language, this is the perfect way to pick up on Java. If not, you'd better go through the "Java Basics Full Course": https://softuni.org/code-lessons/java-basics-full-course-free-13-hours-video-plus-74-exercises
We will go over Java's basic syntax, input and output from the system console, conditional statements (if-else and switch-case), loops (for, while and do-while) and debugging and troubleshooting Java code. If you are well familiar with all of these concepts and you don't need a revision, feel free to skip this section and go to the next one, where we talk about data types and type conversions in Java.If you don't have significant experience in writing Java code, please solve the hands-on exercises in the Judge system. Learning coding is only possible through coding!
