OSI Model - Open Systems InterconnectionAdeel Rasheed
The Open Systems Interconnection (OSI) reference model has served as the most basic elements of computer networking since the inception in 1984. The OSI Reference Model is based on a proposal developed by the International Standards Organization (ISO).
An operating system acts as an interface between the user and computer hardware, controlling program execution and performing basic tasks like file management, memory management, and input/output control. There are four main types of operating systems: monolithic, layered, microkernel, and networked/distributed. A monolithic OS has all components in the kernel, while layered and microkernel OSes separate components into different privilege levels or layers for modularity. Networked/distributed OSes enable accessing resources across multiple connected computers.
P2P networks allow computers to share resources without a centralized server by directly connecting peers in a decentralized manner. Peers act as both suppliers and consumers of resources with access rights governed by individual machine permissions. Popular examples of P2P systems include file sharing apps like Napster and BitTorrent as well as voice chat services like Skype. While P2P networks provide advantages like low costs and ease of use, they can also be less secure and introduce challenges in maintaining version control and duplicates.
The document discusses network models including the OSI model and TCP/IP protocol suite. The OSI model has 7 layers - physical, data link, network, transport, session, presentation, and application layers. Each layer has a specific function in communication. Similarly, the TCP/IP protocol suite has 5 layers that correspond to the OSI layers - physical, data link, network, transport, and application. The document also discusses different types of addresses used in networking including physical, logical, port, and specific addresses.
The document discusses embedded firmware design approaches. It states that there are two basic approaches: the super loop based approach and the embedded operating system based approach.

The card also contains USB ports, an Ethernet port, camera port, GPIO lines, serial ports, SPI port, HDMI port, and I2C port – just about anything you would want for an inexpensive and very powerful robot controller! Lloyd Moore will show us how to get started with this device. Specifically we'll talk about loading and configuring the operating system, installing the Qt (C++) development system, and controlling some of the ports.
The document provides an overview and introduction to using the Intel Edison board, including what Edison is, how to power it up and boot it, connecting to WiFi using ConnMan, getting started with Yocto to build a custom Linux image, and connecting hardware like GPIO. Key topics covered include using MRAA to control GPIO pins from code, booting processes involving the boot ROM and U-Boot, and recommendations to use the mini breakout board or buy from Fry's for beginners.
This document provides steps to connect MicroPython to the SPIKE Prime hub and run code. It introduces the hub module for accessing hub functions like displaying text on the light matrix. The first challenge is to print "Hello World" by importing hub and using hub.display.show(). The document was created by Sanjay and Arvind Seshan to teach MicroPython on SPIKE Prime.
In a nutshell, an Arduino is an open hardware development board that can be used by tinkerers, hobbyists, and makers to design and build devices that interact with the real world. While Arduino refers to a specific type of board design, it can also be used to refer to a company which manufactures a specific implementation of these boards, and is typically also used to describe the community around compatible boards made by other people or companies which function in a similar way.
Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.
- These are slides of the talk given at IEEE International Conference on Software Testing Verification and Validation Workshop, ICSTW 2022.

13. C Command line
To view the contents of a sample sketch, (this
example we’ll look at the contents of
linker_led_test.c) type:
ubuntu@ubuntu:~/c_enviroment/sample$ cat
linker_led_test.c
/*
* LED test program
*/
#include <core.h>
int led_pin = 1;
void setup()
{
if(argc != 2){
goto _help;
}
led_pin = atoi(argv[1]);
if((led_pin < 0) || (led_pin > 13)){
goto _help;
}
pinMode(led_pin, OUTPUT);
return;
_help:
printf("Usage %s LED_PIN_NUM(0-13)n", argv[0]);
exit(-1);
}
void loop()
{
digitalWrite(led_pin, HIGH); // set the LED
on
delay(1000); // wait for a second
digitalWrite(led_pin, LOW); // set the LED
off
delay(1000); // wait for a second
}
14. Creating Your Own Sketch
ubuntu@ubuntu:~/c_enviroment/sample$ nano button_led.c
An empty nano screen should appear.
Copy and paste the following code into it. (Remember to paste in nano at the cursor,
just right click the mouse button).
#include <core.h> // Required first line to run on pcDuino
int ledPin = 8;
int buttonPin = 7;
// variables will change:
int buttonState = 0; // variable for reading the pushbutton status
void setup() {
// initialize the LED pin as an output:
pinMode(ledPin, OUTPUT);
// initialize the pushbutton pin as an input:
pinMode(buttonPin, INPUT);
}
15. Creating Your Own Sketch
void loop(){
// read the state of the pushbutton value:
buttonState = digitalRead(buttonPin);
// check if the pushbutton is pressed.
// if it is, the buttonState is HIGH:
if (buttonState == HIGH) {
// turn LED on:
digitalWrite(ledPin, HIGH);
}
else {
// turn LED off:
digitalWrite(ledPin, LOW);
}
}
16. Creating Your Own Sketch
Modify the Makefile and Compile
ubuntu@ubuntu:~/c_enviroment/sample$ nano Makefile
You will see a section that lists all the OBJS something like:
OBJS = io_test adc_test pwm_test spi_test adxl345_test serial_test liquidcrystal_i2c
liquidcrystal_spi interrupt_test tone_test
OBJS += linker_led_test linker_potentiometer_test linker_tilt_test linker_light_sensor_test

OBJS += pn532_readAllMemoryBlocks pn532readMifareMemory pn532readMifareTargetID
pn532writeMifareMemory
17. Creating Your Own Sketch
We’re going to add a line to the end of this with the name of the
scketch we just created:
OBJS += button_led
Save the file and exit nano using <CTRL>X with a y and <enter>.
We now run make by typing:
ubuntu@ubuntu:~/c_enviroment/sample$ make
You should see a whole bunch of text with the end being:
button_led.c -o ../output/test/button_led ../libarduino.a
If all went well, you can go to the output/test folder and find your executable you have created:
ubuntu@ubuntu:~/c_enviroment/sample$ cd ../output/test/

18. Creating Your Own Sketch
Run Your Sketch
To run it, once you have wired up a switch and led to the right pins, type:
ubuntu@ubuntu:~/c_enviroment/output/test$ ./button_led
To stop the program, <Ctrl>C
A Quick Re-Cap
Add #include <core.h> to the top of your sketch.
Create your sketch in the samples folder (if your familiar with linux,
makefiles, and compiling code, you could set up your own)
Add the filename to the Makefile in the samples folder in the OBJS section
without the .c
Run make
Run the executable from the output/test folder.
You can introduce command line arguments into your sketch to make it more
transportable.

56. Home Automation:IP controllable LED
Many users are asking if the hardware part can be
programmed together with the Ubuntu linux?
Sure. This is the beauty of pcDuino. The Arduino compatible hardware is a native part
of the OS.
pcDuino includes Ethernet port, USB Wifi dongle, so there is no
need for Ethernet shield, Ethernet shield , USB host shield, MP3
shields and so on.
Now, we are going to implement a TCP/IP
socket server on pcDuino to listen to the
data coming from client.
When it
turn on
it will
receive
receives character ’O', it will
the LED, and when it receives ‘F‛,
turn on the LED. No actions if
