What's a good starting point for learning this stuff? Most of my computer knowledge is being able to assemble the parts together, doing network and and system diagnostics, and just fiddling with OSes. (And the one time I used Backtrack + Reaver to hack my friend's wifi lol.) But Idk how to write code (I've tried tutorials but they never seem to stick.) or figure out how the actual circuitry itself works.

That actually is how many people get started.

As for writing code?  I was taught how in school.  There are many different approaches here, from picking it up through python on a linux command line environment, to playing with BASIC on a 8-bit microcomputer from the 1980s, to messing with C.  There really isn’t one right answer, and I’m sure my followers have a variety of suggestions for how best to approach that.

Circuitry...   if you haven’t figured it out by now, I approach this stuff from a vintage computer angle, which ends up having a similar approach to a microcontroller if you separated the chip out into the various components within: CPU, RAM, ROM, graphics, serial/parallel I/O controllers, etc.  This user port on a C64 can feel similar to the digital I/O on an arduino for example.  There was a time when a Radio Shack 100-in-One style kit would be a great answer to this, but times have changed, and most people don’t build analog circuits from scratch any more.  I still do but that’s just how I roll.

We live in an era where arduinos are incredibly inexpensive, and provide a mix between a C-like language and simple circuitry where you can learn the hardware and software aspects hand in hand.  Plus, you can learn the newer device control protocols beyond just serial, like I2C and SPI, and really put some cool stuff together that ends up being practical with not all that much effort as it used to require.  Not to mention, once you find yourself restrained by the limitations of the arduino IDE, you can always leave it behind for higher performance options that grant you greater fine control over your microcontroller.  Then Parallax Propellers, ARM Cortex M0′s, ESP32′s, etc. all become options depending on the type of performance you need to achieve.

I hope that answers your question in a helpful way.

In Tinkercad circuits, choose sensor substitutes.

Tinkercad Circuits has a small library of frequently used electronic parts by design. Beginners may easily explore the complexities of the electrical world without feeling overwhelmed thanks to this curation. The drawback is that you can't build an identical replica of your circuit in the simulator if you're looking for a particularly specific part number or version of a sensor that isn't there in the parts drawer.

Fortunately for all of us, there's usually a solution to represent your missing component by using a similar one instead. A few major groups of sensors contain many similar sensors. You can choose an appropriate replacement for your Tinkercad Circuit with the aid of this tutorial.

Digital sensors

As they are activated, analogue sensors provide a changing voltage and resistance. Potentiometers are the most common sort of analogue sensor, but other more specialised varieties exist as well, such as flex sensors, photoresistors, microphones, some temperature sensors, force-sensitive resistors (pressure sensors), piezo components, and some IR distance sensors. Analogue inputs can be read using Arduino's analogRead() function or Tinkercad's "read analogue pin" block.

We advise using a potentiometer or TMP36 temperature sensor as an alternative in Tinkercad circuits if the analogue sensor you wish to use has three pins, as they both have three pins (power, ground, and signal). The TMP36 requires a regulated power supply voltage (2.7-5.5V), whereas a potentiometer is an only resistive sensor. This is an important distinction to make.

The only viable alternative in Tinkercad Circuits if your analogue sensor only has two pins is a two-pin photoresistor (the piezo element in Tinkercad Circuits can only be used as an output).

Electronic Sensors

High/low voltage signals and more complicated digital signals are the two primary categories of digital sensors.

Pushbuttons, switches, tilt ball sensors, magnetic reed switches, PIR motion sensors, and vibration switches are a few examples of sensors in this category. Try one of the many switches and pushbuttons available in Tinkercad Circuits, but also have a look at the tilt sensor and PIR motion sensor, whose simulations might more precisely resemble whatever digital sensor you are trying to replicate. Using digitalRead();, Arduino may read signals with high or low voltage. "Read digital pin" is the Tinkercad block for digital inputs. Launch the simulation below, then click on each sensor to see what happens:

The swap possibilities are more constrained for more sophisticated sensors that make use of data protocols like i2c. There isn't a component that can act as your i2c device, yet you might be able to use the extra library by putting it into your Arduino sketch.

Further Resources

When you make a substitution, we advise using the annotation tool to put notes on your circuit. Even though you couldn't illustrate the precise correct component, this can still aid in communicating the intent.

Don't overlook Tinkercad Circuits' starters, which can get you up and going with several fundamental sensors very quickly (in the components drawer).

Try out our beginner-level Arduino courses using Tinkercad Circuits to learn more about how to add sensors into your Arduino projects.

Send the team your requests for components, please! Although we deliberately limit the number of available components, we are constantly considering what we can add to make Tinkercad Circuits even better. Your criticism is a gift. I'm grateful.

Basic Understanding of MIPI I3C Protocol

Hello, and welcome to my blog! Today I’m going to share with you some insights on the MIPI I3C protocol, which is a new standard for interconnecting sensors and peripherals in mobile devices. MIPI I3C stands for Mobile Industry Processor Interface — Improved Inter-Integrated Circuit. It is a low-power, high-speed, bi-directional serial bus that supports multiple masters and slaves. It also offers advanced features such as dynamic address assignment, in-band interrupts, hot-join, and command modes. MIPI I3C is designed to be backward compatible with I2C, but with much higher performance and efficiency. It can achieve up to 12.5 Mbps data rate with only two wires: SCL (clock) and SDA (data). It can also support up to 12.7 devices per bus segment, compared to only 112 devices for I2C. MIPI I3C is ideal for connecting sensors such as accelerometers, gyroscopes, magnetometers, pressure sensors, proximity sensors, ambient light sensors, and more. It can also be used for other peripherals such as touch controllers, audio codecs, display controllers, and power management ICs. MIPI I3C is a versatile and powerful protocol that can simplify the design and integration of mobile devices. 

If you are interested to understand more about the MIPI I3C Protocol, then you can go through the PiEmbSysTech MIPI I3C Protocol Tutorial Blog. If you have any questions or query, that you need to get answer or you have any idea to share it with the community, you can use Piest Forum.

Just a quick walk through how to use the SD card module with Arduino. It is the same for Micro SD card modules. The Arduino official site provide a library for this purpose, and I will describe how I used this library and explain what each function does.

The SD card module communicates with the Arduino over the serial peripheral interface (SPI) communication protocol. It can be simply connected to the Arduino’s hardware SPI pins. LCD with I2C Module to the Arduino As the name implies, the LCD module communicates with Arduino through I2C communication. After a week of research, brainstorming and studying we ended up making, the SD-CARD (social distancing icard). The SD-CARD consists of an Arduino Nano which is connected with a buzzer, an ultrasonic sensor and 2 LEDs. The ultrasonic sensor calculates the distance between the person wearing it and people near him/her.

Buy the Arduino from: Banggood | Amazon

Buy SD Card Module from: Amazon | Banggood

I have not tested this library with all the SD card modules, but I think it should work for majority of them, unless you are told by the seller that you should use a different library.

The Library uses standard SPI interface for communication, which hasSPI buses, MISO, MOSI, SCK (CLK) and a chip select signal pin, CS.

(pic)

** MOSI – pin 11 ** MISO – pin 12 ** SCK (CLK) – pin 13 ** CS – pin 4

The default Arduino library for SD card is huge! With the example read/write sketch, when compiled it’s 13690 Bytes which is half of the available flash space on an Arduino pro mini!

So if you are tight in sketch space, it’s a good idea to find a smaller library. Depends on the SD cards you have and the format you want to use, you have these options.

FAT32 Format (larger than 2GB)

Adafruit SD (almost the same as Arduino SD, except a few optimization on SRAM memory)

FAT16 Format (smaller than 2GB)

I haven’t tested all of these libraries, so do your research and test them before using it. Here I will show you how to use the Arduino SD library.

The SD library comes with the Arduino IDE, so you don’t need to download it. It needs to be include at the beginning of the sketch.

Including `SD.h` automatically creates a global “SD” object which can be interacted within a similar manner to other standard global objects like “Serial”.

Read from SD card

First you need top open the file first.

It will return false if it fails to open the file, so check dataFile before using it. The “read” function reads the file line by line, so you will have to use a while loop, until it fail to reach the end of the file. Now you can write to the file using this.

Note that you need to close the file after finished reading it. Also, you can only open one file at a time, if you want to read the next file, you need to close the current file first.

Write to SD card

First you need to open the file you want to write to with “FILE_WRITE” parameter.

The “open” function takes two parameters, file location and mode (only required for “Write”, if missing by default it opens the file in Read-Only mode). It will return false if it fails to open the file, so check dataFile before using it. Now you can write to the file using this.

Note that you need to close the file after writing to it. Also, you can only open one file at a time, if you want to open the next file, you need to close the current file first.

Check if a File Exists

Create a Text File on SD Card

There isn’t a function for this purposes, but you can open a file with “FILE_WRITE” mode to create a file, if this file doesn’t exist.

Delete a File on SD card

List All the files on SD card

There isn’t a function for this in the library, but we can create a custom function to achieve this purpose. This function is from the example sketch in the Library. It prints the file directory to serial monitor.

Space Image Sound - Week 11

This is insane. 

I have thirteen versions of code to write by Friday and ideally Wednesday as well as about 3-5 hours of soldering in Mechatronics, which is increasingly challenging with it’s limited opening hours. Throughout this week I will definitely be burning some serious midnight oil getting this done, and I’m going to have to ask Tim and Simon for help, even though the technical side of the project is not their job. 

Tim has agreed to help me with the soldering which is awesome as it will cut down the time I need to spend on the project, and also helps to even out the effort that we are all putting in. I’ve peeled off the music program in Processing to them. Tim & Simon have finished all of the music, and I really want to get this working for the amount of work I’ve put in, and they’ve put in so far. If I can’t solve the technical issues, then the project does nothing. Better get to it.

At the end of last week, I created this to do list:

NES - Any Button Update:

Since the NES and SNES code were so similar I combined the two into one program to simplify things for later which saved me two steps in this list which is great.

SNES - Any Button Update: Done

N64 - Any Button Update: 

I didn’t have the time to make the N64 controller work as I had to focus on making a viable version of the outcome for submission. This was the hardest piece of code I had encountered because I was just stuck with bugs no matter what I tried. It was completely ironic that I promised to produce the technical side of the project, and then in the last minute ditched the hardest part and gave it to the others. 

Tim and Simon began to try and understand the code and absolutely aced this. I had spent around 20 hours researching what to do with this code and had no success. After two hours, Tim found an Arduino library which basically did the code for us. Within the day of me asking them to try and get it to work, they had it working and inside an incredibly efficient piece of code which is great.

PS1 - Any Button Update:

This piece of code ran quite smoothly as well, as I just had to adapt it from what I had worked on for the NES and SNES controllers. I had it working for PS1 controllers, and I had hoped to follow the same strategy as NES/SNES to simply duplicate a method and run two controllers in the same arduino. I had this working for PS1, but I was about to run into issues integrating PS2. I also found at this point I had the perfect amount of Arduino pins which was great.

PS2 - Any Button Update:

I had another issue to tackle here. The way that the PS2_X library was coded, I couldn’t use two Playstation controllers in one Arduino, and I couldn’t duplicate the code. I had designed the entire program to only require one way serial communication, and not need multiple Arduino’s which made me hit another speed bump. Luckily I found a simple solution by googling “can I daisychain Arduino’s?”.

PS2 - Daisy chain to Main Arduino Update:

What I came across was ‘12C Communication’.

https://howtomechatronics.com/tutorials/arduino/how-i2c-communication-works-and-how-to-use-it-with-arduino/

First I wrote this code using their example of blinking an LED based off code form the other Arduino, then I re-wrote it to run the Playstation controller and tell the other Arduino when any button had been pressed, in the same way I had done with all of the other controllers.

I was then able to daisy chain two Arduino’s together in a Master/Slave configuration. The Playstation 1 controller was plugged into the ‘master’ arduino, which sent data to the ‘slave’ arduino. The ‘slave’ arduino was my main Arduino which could then use the data from all of the controllers to tell processing what tracks to play as well as run the glitch protocol, which I hadn’t made at this point.

Master Program - Merge NES and SNES Programs: Done

Master Program - Merge PSX with NES and SNES

This merge was relatively easy. However every time I merged a program I began to realise I should have coded more efficiently, but that is something I would have done with more time.

Master Program - Merge Daisychained PS1 with PS2, NES and SNES

This is simple, and now I had the daisy chained controller from earlier working with the other code meaning all I needed to add was the N64 code.

Master Program - Merge N64 with all other controllers

Once Tim and Simon got this working this was a smooth and easy merge. This completed merging the programs for the controllers, and put me closer to being finished than ever before. It’s great that they got this N64 code working as I was quite concerned that it wouldn’t function.

Master Program - Write ‘glitching’ protocol

It took a couple of versions of code to make this operational, but eventually I was able to make the code execute the visual glitching which is the most major visual part of the final outcome. Since processing just reads from the serial monitor, it was easy to add Processing communication at the same time I did this for the later sound output.

https://learn.sparkfun.com/tutorials/connecting-arduino-to-processing/all

Master Program - Add processing communication for music: Done

Master Program - Add AV control to the controllers

This created the ‘finished’ program which was ready to run. I merged my past AV switcher code into this program and I had the five controllers controlling the video outputs. All seemed well, however, there was something I was curious about from the beginning that I couldn’t answer until I was done (which I also didn’t think would be the day of the deadline). This was - will the controllers work in the consoles when they are spliced into the Arduino?

Now that it was all coming together, it was time to put it all together. I plugged all of the controllers, the two Arduino’s and the AV switcher into one curcuit and BOOM! It worked. The AV’s switch and the sound is responsive.

Now I need to do some slight changing on the code because the buttons on the N64 controller press themselves sometimes I want to create a ‘safety net’. However, this is something I can do for open studio and I am confident I now have a completed proof of concept for submission. It’s not completed in the way I had hoped, we didn’t put time into our installation and its a little glitchy - which kind of adds to the experience in its own way.

Master Program - Add 'controller security’

Now cool, its 10pm on Thursday night and its all due in the morning. I’m being kicked out of studio by security as its time to go. The sound works (cheers Tim and Simon), the AV’s glitch and all I have is a little glitch I can fix later. Nice. 

Wait? Can I play the games? No! 

The NES crashes the console, and somehow the console is powered by the Arduino through the controller port, so for the safety of the console we now can’t play it with the same controller.

The SNES with a little extra code doesn’t mind at all and its smooth sailing as planned. 

The N64 plays like a gem with no extra code.

The PS1 and PS2 controllers are completely unresponsive, and due to the structure of the code in the library its no easy fix to figure out how to allow them to be played with the same controllers.

This is a massive blow to the outcome, and one I couldn’t have tested until I finished the code, which is hours before submission. I have spent so many hours on this and I really want it to work. Unfortunately I just don’t know how. I’m sure with more time I could iron out these errors, but until then the visuals and audio are sick and its great to have an outcome.

Another issue is that PAL and NTSC don’t glitch together well and overall PAL glitches better. So since the NES and SNES are NTSC the glitches don’t look as good as they could with some of the consoles.

It definitely took at least four times longer than I thought, and I shouldn’t have taken on so much technical stuff. However, this was a passion project as I really enjoy working with retro tech and especially retro gaming tech. Thanks to Tim and Simon for all your hard work, I couldn’t have done it without you.

Future Directions:

Make the games play

Fix the N64 Glitch 

Create a good installation for it.

Source all PAL based consoles

Pomodoro timer and alarm clock Experiment 2: LCD Integration

About LCDs and the I2C interface

As per the previous experiment, let’s begin by understanding what an LCD is. According to wikipedia: “ A liquid-crystal display (LCD) is a flat-panel display or other electronically modulated optical device that uses the light-modulating properties of liquid crystals. Liquid crystals do not emit light directly, instead using a backlight or reflector to produce images in color or monochrome. “ 

So, in order to display data to the user, we use an LCD screen. The one we are using can display 16 characters per line, consisting of a total of 2 lines (16*2), but there are other screens of different sizes (such as 20*4). The LCD screens can communicate with the microcontroller (I/O communication) in different ways. For our experiment, we will be using the I2C interface. The I2C interface links the 16 pins of the classical LCD screen into only 4 pins: GND (for ground), VCC (for powering it up), SDA and SCL (for communication protocols). The I2C interface board also contains a potentiometer (the blue square) that regulates the light intensity of the character boxes. Note that in case your characters are barely visible, you might need to turn the potentiometer to increase the intensity. We can also use the two additional pins located on the left side of the back (which are usually covered) to connect them to a potentiometer.

Connecting the physical parts

Similar to the last experiment, we begin by connecting Male to Female cables to the LCD screen.

Next, we connect the wires linked to VCC and GND onto the breadboard. VCC to any column linked to the Positive Bus and GND to any other column linked to the Negative Bus, just like how we connected the Real-time Clock. Next, we connect the two wires coming from the SDA and SCL pins to the pins 20 (SDA) and 21(SCL) accordingly. Some microcontrollers might have different numbers for those pins, but they would still be labeled properly, so look on your board for those two names. 

After that, plug the potentiometer into the breadboard, and connect it to the two wires from the opposite side to any two of the columns where the potentiometer is plugged into. 

‘A potentiometer is a three-terminal resistor with a sliding or rotating contact that forms an adjustable voltage divider. If only two terminals are used, one end and the wiper, it acts as a variable resistor or rheostat’ (Wikipedia, 2019). It’s purpose is to regulate the intensity of the voltage that passes through the LCD screen by opposing resistance.

This is the diagram of our circuit:

Note: the diagram is not entirely accurate as there was no LCD screen available for illustration that had the I2C interface. Consider the first pin to be GND, the second VCC, the third SDA, the fourth SCL, and the 5th and the 6th the two isolated pins on the left side of the back of the I2C interface.

Programming the LCD

In order to program the LCD, we need to use an additional library. The LiquidCrystal_I2C library that I used can be found at this link. 

This library allows us to construct an object which contains methods that control the LCD. First, we construct the object with the following line: 

LiquidCrystal_I2C lcd(0x27,16,2);

The first parameter passed is the address of the screen. I believe that all 16*2 sized LCD screens will have the address 0x27, while 20*4 sized LCD screens have the address  0x3F. 

The following sketch (provided by instructables.com) can help you identify the right address of your screen:

Note: the library needed for this particular sketch can be downloaded at this link.

The second and third parameter of the constructor is related to the size of the screen: the number of characters per line, the number of lines.

In the setup() method of the sketch, we call the following lines to initialize the screen:

 lcd.init();  lcd.backlight();

In the loop() method, we do the same thing as from the last experiment, but we are now printing on the lcd object instead of the Serial, as well as using the lcd.clear() method to clear previous content and lcd.setCursor() to tell the screen on which line to display the text.

When displaying text on the LCD, always keep in mind that we can have a maximum of 16 characters per line, so adjust it accordingly.

The code of the complete sketch:

After uploading the following code to the microcontroller, this is what you should achieve:

If you want your values to be displayed in a double digit manner (e.g. show 05 instead of 5), add the following line of code for every variable printed:

This video explains the flow of electricity in this circuit.

In the next experiment, we will be adding a push-button and a buzzer to our project, have the button turn the display on and off, and the buzzer trigger at certain intervals of time.

The complete code can be found HERE !

The source code can be found HERE!

Technical evaluation

To get the LCD to work was quite troublesome at first. The first LCD screen I bought did not have an I2C interface, and it required soldering, for which I did not have the tools at hand. I had to purchase a second one, but that was still not as easy as I hoped. There are a lot of libraries for LCD screens, and it took about four tries until I have found one compatible with my screen. Once I managed to get the circuit going, I encountered another issue. The characters on the screen were very faded. After inspecting the I2C interface, I noticed that there is an additional potentiometer which had to be spinned a little to increase the intensity of the light. That solved my issue. After that, printing characters to it was very simple and also fun. Apart from those issues, everything went quite smoothly. I consider this to be one of my greatest achievements in using physical components, as I always thought LCD screens were quite a complicated tool, and this made me more confident that I could use more advanced parts in the future.

Project Overview

This NodeMCU IoT project is a simple demonstration on how to send sensor data to the Internet. Powered by a NodeMCU ESP8266 microcontroller, this project is able to show temperature, humidity and atmospheric pressure to any MQTT subscriber.

Introduction

Using MQTT is much faster than using HTTP because of reduced overhead. In fact, MQTT is one of the preferred protocols for Internet of Things. To use MQTT, we need a broker and there are lots of them! For this project, I used Shiftr.IO. I already detailed how to use the MQTT protocol with the NodeMCU so kindly check that out first.

Materials

For temperature and humidity, I used SHT1x from DFRobot. For the atmospheric sensor, I used the old reliable BMP085. My Arduino BMP085 tutorial covers how to use this sensor with the Arduino. Since the NodeMCU uses the same Arduino IDE and as long as the special core is installed, a similar sketch from that tutorial will be used here.

[tie_list type=”checklist”]

NodeMCU

SHT1X Temperature and Humidity Sensor

BMP085 Atmospheric Pressure Sensor

[/tie_list]

Another requirement for this project is an account in Shiftr.IO which is totally free. I’ve created an “environment-monitor” channel in Shiftr and was promptly given username and passwords.

The MQTT library is required and is downloadable here. Also, you’ll be needing the SHT1X library and the BMP085 library, both thankfully are NodeMCU-compatible.

Wiring Diagram

The SHT1X library uses software SPI while the BMP085 uses I2C. The default I2C pins of the NodeMCU is at D1 (SCL) and D2 (SDA) or GPIO5 and GPIO4. Naturally, the BMP085’s SDA and SCL pins should be connected to those pins. As for the the SHT1X, I decided to use the D3 and D4 pins for clock and data respectively. Here is the Fritzing diagram:

Arduino Sketch

The sketch is similar to that in my MQTT tutorial [https://www.teachmemicro.com/nodemcu-mqtt-tutorial/]. First, connect to the MQTT broker through

client.begin("broker.shiftr.io", WiFiclient);

Then I connected to the MQTT channel using

client.connect("environment-monitor", "<username>", "<password>")

The username and password is found on the URL of the MQTT channel. For example, if this is your URL: mqtt://7fb2fd2f:b9f1e26ae8d3dac8@broker.shiftr.io ( found in namespace settings). Your username is 7fb2fd2f and the password is b9f1e26ae8d3dac8.

To publish data, I used

client.publish("environment-monitor/temperature", (String)temp_c);

There is no need to create the /temperature topic as it’s automatically created once you call the function above. Of course, you can publish multiple topics:

client.publish("environment-monitor/temperature", (String)temp_c); client.publish("environment-monitor/humidity", (String)humidity); client.publish("environment-monitor/pressure", (String)pressure);

Anyway, here’s the full sketch:

Erlang user conference notes, translated.

Jonas Boner, author of Akka ---------------------------- Talks a lot about reliability, resiliency but doesn't say how, instead of it shows nice pictures with meercats, Conway's game of life and so on. Let us split the system to number of interacting agents, and let them interact. All states should be known, unknown states should not exist (hard to argue). How to know all states is unknown though. Converging promises and diverging commands. Kenneth Lundin, OTP 20 highlights --------------------------------- A lot of improvements: garbage collector, binary parts, unicode aroms, better maps, ets, and so on. Failed to split OTP as planned, however work is going on. See the changelog, release is planned at 21 of June. Jesper L. Andersen, GraphQL in Erlang ------------------------------------- http://ift.tt/2qdi8rk GraphQL allows a client to declare what it wants from sever. What is possible is described by schema, schema is compiiled and checked server-side. Query interpretation takes microseconds, most of load is to fetch data from storages. Each schema type is represented by Eralng module with known API. Types in GraphQL and types theory relation (positive/negative types), this is not emphasized in GraphQL docs. Author wrote a lenghtly tutorial. Paweł Antemijczuk и Maarten Faddegon, Anti-Patterns in the Wild --------------------------------------------------------------- How write a bad code in Erlang. Same old story: don't write huge functions, don't use huge state, don't nest case clauses. They fear to use Erlando in production due to maintenance concerns, they tried and failed Wrangler (steep learning curve, unclear results, don't like Emacs). To sum up: it is impossible to refactor Erlang code automatically and semi-automaticcally at the moment and nearest future. Write tests instead. Mark Allen, Sagas in Erlang: Distributed Transactions Without Locks ------------------------------------------------------------------- For the reason unknown declared a left fold operation a transaction (it is not), distributed in fact not so distributed, and so on. Why to talk about this is unclear. Peer Stritzinger, Fixing Erlang’s Distribution Protocol ------------------------------------------------------- They tried to use Erlang on microcomputers for industrial automation and then discovered that Erlang distribution protocol is broken by design: 1. full-mesh networking model 2. messages are processed sequentally, and one huge can block whole queue 3. primitive security model Because of that they want to fix the protocol, however how he described the fix looks more or less like TCP/IP stack itself but over the node links (which are TCP already). Weird. Peter Van Roy, Ditching the Data Center: How to Stop Worrying and Love the Edge ------------------------------------------------------------------------------- This time truly distributed computations over unreliable network. Nodes know about each other with Gossip family of protocols, all calculations should be with CRDT. At the moment CRDT have limited use, but where they could be used then use cases are good. They are doing research, have funding till 2020, and plans till 2050. Impressive. The idea is to write programs as expressions over CRDT, sort of map: A -> B, and there is a special language lasp. Kostis Sagonas, Adventures in Corfu: Testing and Verifying Chain Repair Protocols using Concuerror -------------------------------------------------------------------------------------------------- Started with some Greece advertisement, however continued: they have a tool to test concurrency in Erlang by building all possible message sequence combinations, and trying all of them. If a program fails under this test then there is certainly a bug, and if program doesn't fail, then there are no bugs (with high probability). All possible cases could be tried, but it takes time. There are some ways to speed up process, and plans how to make it parallel. One unexpected use case: Scott Lystig Fritchie who works on CorfuDB discovered a bug in distribution protocol, but concuerror discovered a bug in suggested fix to previous bug. This was achieved by modelling protocol with Erlang entities (processes, messages). Very interesting. Justin Schneck, Keynote: The Demarcation of the Edge of Innovation ------------------------------------------------------------------ Talks about dependencies, food recepies, all are doing something, everything depends on everything, and so on. They took Linux kernel, and Erlang, and made it run on Raspberri Pi, and then called it a platform. Was unable to stand this marketing bullshit and left. Andrea Leopardi, Update from the Elixir Core Team ------------------------------------------------- Elixir is stable and evolving, planned release is 1.5, good interaction with OTP team, built-in property tester, and so on. Clara Benac Earle, Building Distributed and Robust Multi-Agent Systems (MAS) ---------------------------------------------------------------------------- Talks about agents with beliefs, goals and logic. Some people describe those agents using special language Jason, JVM targeted. Speakers were able to translate this language to BEAM and are very happy. Robustness and distribution are inherited from BEAM, sort of. Loïc Hoguin, A Tale of 2.0 Cowboys ----------------------------------- Soon Cowboy 2.0 will be released with HTTP/2 support and better architecture. Used maps everywhere, better process management, gen_statem. Handlers could return list of commands. Rewrote whole documentation in php-style (one function per page), wrote a lot of tests for specs, a lot of work. Cowboy 1.x is a part of RabbitMQ, and other his projects. Has plans to write REST framework, nobody are doing REST correctly. Much sponsors left past two years, has no money because of that. Claudia Doppioslash, Building Single Page Web Applications with Purescript and Erlang ------------------------------------------------------------------------------------- Rewrote the app from Elm to Purescript (last year talk was about Elm). Elm is not good enough (simple types, one true architecture). Purescript has rich type system, and could be compiled to Erlang. They are using BERT between client and server due to encoding/decoding server-side is much quickier than JSON. How Erlang is related to this project is completely unclear. Adam Lindberg, Robotics and Sensors Using Erlang on Embedded Systems with GRiSP ------------------------------------------------------------------------------- Developed a custom atmel-based board with rich periphery (wifi, usb, gpio, i2c, spi, uart, 1-wire), and managed to run RTEMS with BEAM on it. This allows to use Erlang to manage and program the device. Erlang used is outdated (16.x), they have plans to update it alongside with build process. Selling price is 180 euro, intended use case is industrial automation. Unclear though why is this better than Orange Pi ($10 with delivery) with Armbian and Erlang. Joe Armstrong и Sam Aaron, Distributed Jamming and Composition with Sonic Pi and Erlang --------------------------------------------------------------------------------------- A stand-up comedy show. Joe Armstrong discovered MIDI, and is eager to share this knowledge with broad audience. Suddenly MIDI has messages, and you can exchange them over network. Sam Aaron demonstrated how his Sonic Pi works. Here we have a program to generate sounds, how cool it is. Also you can have effects. Logic Pro is written by idiots. How Erlang is related, again? comments via jamhed http://ift.tt/2srOSCR
