Programming test

Please note All programs must work on Linux.

#1: N-last lines Make a program that reads last N lines from file F. Program must be written in either C or C++. Program may be executed like this: ./program -n 10 file.txt Above should display up to 10 last lines from file.txt. Arguments that must be implemented are: -n Read N lines from file F -f Wait for new lines in file as they are written and output them on terminal

#2: System information Make a program that shows some basic information about a Linux system. Program must be written in either C or C++. Program may be executed like this: ./program Program output may show the following: Linux kernel: 3.10.2 Architecture: 64-bit Available Memory: 1000M Free Memory: 10MB eth0 IP address: 10.1.2.3 sda disk size: 250GB Current username: root All this information is to be collected via available system calls or via files exposed via Linux kernel. You must not execute external programs to get such information.

#3: IP address lookup Program must be written in either C or C++. Program may be executed like this: ./program --database ./database.txt 10.1.2.3 database.txt will be a text file that contains IP address ranges in form of: 10.1.0.0/16 127.0.0.0/8 192.168.8.0/24 ... The task of the program is to find and print out all ranges for the IP address supplied as an argument. Expected output for the above may be: 10.1.0.0/16 SQLlite backend Make a second version of the program that does the same, but this time, instead of plaintext file have it read SQLite database as a file. You have all freedom to design SQLite database.

#4: User administration (JavaScript) Make a test admin web page that has the following: Add User Edit User Delete User Search User Each user should have at least these properties: Full name Username E-mail Password Other properties may be implemented. List should have pagination at certain record limit (e.g. 10 records per page). Bonus points: Local storage of data Looks good (and font icons) Duplicates not allowed Search works well Performance Additional clever bits Make it so that it works as a single JavaScript-based web page and make sure it looks good (it may be split into multiple resources, stylesheets etc. but it is not to be written in some server-side language). This has to be done without any complex JavaScript frameworks (such as Ember, Angular, extjs etc) and it should work on modern browsers (Internet Explorer is not required).

#5: User administration (PHP) Same as task #4, but implemented in PHP. You have a freedom to implement it as you wish.
