 1 | # CONCOURSE CONTINUOUS INTEGRATION
 2 | 
 3 | I use concourse to automate,
 4 | 
 5 | * Use README for
 6 |   [GitHub Webpage](https://jeffdecola.github.io/my-cheat-sheets/)
 7 | * Alert me of the progress via repo status and slack
 8 | 
 9 | ## PIPELINE
10 | 
11 | The concourse
12 | [pipeline.yml](https://github.com/JeffDeCola/my-cheat-sheets/blob/master/ci/pipeline.yml)
13 | shows the entire ci flow,
14 |

16 | 
17 | ## JOBS, TASKS AND RESOURCE TYPES
18 | 
19 | Concourse Jobs and Tasks
20 | 
21 | * `job-readme-github-pages` runs task
22 |   [task-readme-github-pages.yml](https://github.com/JeffDeCola/my-cheat-sheets/blob/master/ci/tasks/task-readme-github-pages.yml)
23 |   that kicks off shell script
24 |   [readme-github-pages.sh](https://github.com/JeffDeCola/my-cheat-sheets/blob/master/ci/scripts/readme-github-pages.sh)
25 | 
26 | Concourse Resources
27 | 
28 | * `my-cheat-sheets` uses a resource type
29 |   [docker-image](https://hub.docker.com/r/concourse/git-resource/)
30 |   to PULL a repo from github
31 | * `resource-slack-alert` uses a resource type
32 |   [docker image](https://hub.docker.com/r/cfcommunity/slack-notification-resource)
33 |   that will notify slack on your progress
34 | * `resource-repo-status` uses a resource type
35 |   [docker image](https://hub.docker.com/r/jeffdecola/github-status-resource-clone)
36 |   that will update your git status for that particular commit

21 | 
22 | Arm Holdings develops CPU IP cores based on architecture
23 | and licenses it to other companies, who design their own products.
24 | 
25 | ## WHY USE SAME ARCHITECTURE
26 | 
27 | The benefit of using the same HW architecture is
28 | everyone can use the same software library for an OS distribution.
29 | For example, ubuntu on a Hummingboard can get software from
30 | the ARM7 distro.
31 | 
32 | ## ARM CORES USE ARM ARCHITECTURE

 9 | _"I do not know what I may appear to the world; but to myself, I seem to have been
10 | only like a boy playing on the seashore, and diverting myself now and then in
11 | finding a smoother pebble or prettier shell than ordinary, while the great ocean
12 | of truth lay all undiscovered before me."_
13 | 
14 | \- **Isaac Newton**
15 | 
16 | _"The first principle is that you must not fool yourself and you are the easiest
17 | person to fool."_
18 | 
19 | \- **Richard Feynman**
20 | 
21 | _"Tomorrow, and tomorrow, and tomorrow,
22 | Creeps in this petty pace from day to day,
23 | To the last syllable of recorded time;
24 | And all our yesterdays have lighted fools
25 | The way to dusty death. Out, out, brief candle!
26 | Life's but a walking shadow, a poor player,
27 | That struts and frets his hour upon the stage,
28 | And then is heard no more. It is a tale
29 | Told by an idiot, full of sound and fury,
30 | Signifying nothing."_

13 | ## NAND TYPES
14 | 
15 | _NAND_ is a type of non-volatile flash memory, meaning it does not
16 | require power to retain or store data.
17 | 
18 | NAND falls into several types from single layer to quad layer,
19 | 
20 | * SLC (Single Level Cell) - **BEST BUT EXPENSIVE**
21 | * eMLC (Enterprise Multi Level Cell) **BEST CHOICE**
22 | * MLC (Multi Level Cell)
23 | * TLC (Triple Level Cell)
24 | * QLC (Quad Level Cell) - **WORST** - DO NOT BUY

13 | * [VIRTUAL MACHINE / CONTAINER](https://github.com/JeffDeCola/my-cheat-sheets/tree/master/software/development/development-environments/software-install-methods-cheat-sheet#virtual-machine--container)
14 | 
15 | ## SOURCE
16 | 
17 | The purest form of the install. Download source code
18 | (e.g. _go, python c, etc..._) and compile to a binary.
19 | 
20 | * PROS
21 |   * The latest software compiled correctly on your machine
22 | * CONS
23 |   * Configuration and provisioning
24 |   * Updating software requires a recompile
25 | 
26 | ## BINARY
27 | 
28 | Download the binary (e.g. _something.exe_) that has been already
29 | compiled for your machine. For example,
30 | [I install golang](https://github.com/JeffDeCola/my-linux-shell-scripts/tree/master/go/go-install-new-version)
31 | this way on my machine.
32 | 
33 | * PROS
34 |   * Pre-compiled for your OS
35 | * CONS
36 |   * May be an older version
37 | 
38 | ## INSTALLER / PACKAGES
39 | 
40 | An installer/provisioning type program is
41 | used to install your App.
42 | 
43 | Linux has many types of software that can be used
44 | as installers (and I use this term very loosely)
45 | since they are much more than just installation (e.g. _BOSH and
46 | [ansible](https://github.com/JeffDeCola/my-cheat-sheets/tree/master/software/operations/configuration-management/ansible-cheat-sheet)_).
47 | 
48 | Linux systems use packages, that contains everything a particular
49 | program needs to run. (e.g. _`apt-get` is used in ubuntu_).
50 | 
51 | * PROS
52 |   * Can tailor install to your machine
53 | * CONS
54 |   * None
55 | 
56 | ## VIRTUAL MACHINE / CONTAINER
57 | 
58 | Sometimes its easier just to grab a `virtual machine` or `container`
59 | where someone has already done all, if not most of the work.
60 | 
61 | For example, [vagrant](https://github.com/JeffDeCola/my-cheat-sheets/tree/master/software/development/development-environments/vagrant-cheat-sheet)
62 | will allow you to quickly fire up a VM.
63 | Or use [docker](https://github.com/JeffDeCola/my-cheat-sheets/tree/master/software/operations/orchestration/builds-deployment-containers/docker-cheat-sheet)
64 | to get a container with the App you want.
65 | 
66 | * PROS
67 |   * Easy to fire up and shut down
68 | * CONS
69 |   * Need VM/Container software installed on machine
70 |   * Configuration and provisioning can be tricky
71 |   * Not really a good long term solution
72 |   * Find a new image for another version

19 | ## ERROR HANDLING
20 | 
21 | I use the go package
22 | [errors](http://github.com/pkg/errors).
23 | 
24 | Go doesn’t have exceptions, so it doesn’t have try, catch or anything similar.
25 | So how do we handle errors?
26 | 
27 | * Functions return errors just like any other value. `Multiple return values`
28 |   distinguish errors from normal return values.
29 | * Errors are the last return value and have type error, a built-in interface.
30 | * Errors are handled by checking the value(s) returned from a function.
31 | * A nil in the error type means no error

33 | As and example of a function that has multiple return values, including type error.
34 | 
35 | ```go
36 | // YOUR FUNCTION THAT RETURNS AN ERROR TYPE
37 | func a(x int) (int, error) {
38 |     if x == 42 {
39 |         // Make your error
40 |         return -1, errors.New("can't work with 42")
41 |     }
42 |     return x + 3, nil
43 | }
44 | 
45 | // YOUR ERROR CHECKER
46 | func checkErr(err error) {
47 |     if err != nil {
48 |         fmt.Printf("Error is %+v\n", err)
49 |         log.Fatal("ERROR:", err)
50 |     }
51 | }
52 | 
53 | func main() {
54 |     //MULTIPLE RETURN VALUES (Simpler form)
55 |     r, err = b(42)
56 |     checkErr(err)
57 |     fmt.Println("Returned", r)

63 | for an example using `github.com/pkg/errors` package.
64 | 
65 | ## LOGGING
66 | 
67 | A logger or logging give you information from a running program.
68 | Typically it uses stderr or a file.
69 | 
70 | I like the following levels,
71 | 
72 | * Panic (optional)
73 | * Fatal
74 | * Error
75 | * Warning
76 | * Info
77 | * Debug
78 | * Trace
79 | 
80 | Refer to
81 | [my-go-examples](https://github.com/JeffDeCola/my-go-examples/tree/master/common-go/logging/jeffs-logger)
82 | for an example using

19 | ## GO EXECUTABLE
20 | 
21 | A go executable is made up of,
22 | 
23 | * Your compiled code
24 | * Go runtime environment
25 | 
26 | This diagram shows how everything fits together.
27 | The bottom line, go likes to put goroutines on threads.  And the goroutines
28 | will bounce all over the place as the thread schedulers schedule things.
29 | 
30 | ![IMAGE - go-executable-your-code-and-go-runtime - IMAGE](../../../../docs/pics/software/development/go-executable-your-code-and-go-runtime.svg)
31 | 
32 | ## GO RUNTIME (GOROUTINE SCHEDULER)
33 | 
34 | The go runtime manages scheduling, garbage collection,
35 | and the runtime environment for goroutines among other
36 | things. Since go provides high level constructs
37 | a runtime infrastructure is required to support these features.
38 | 
39 | One of the more important aspects of the go runtime is the
40 | goroutine scheduler. The runtime keeps track
41 | of each goroutine, and will schedule them to run in turn
42 | on a pool of threads belonging to the process.
43 | 
44 | ## GOROUTINES & THREADS
45 | 
46 | Goroutines are separate from threads but rely upon them to run, and
47 | scheduling goroutines onto threads effectively is crucial for
48 | the efficient performance of Go programs.
49 | The idea behind goroutines is that they are capable of running concurrently,
50 | like threads, but goroutines are also extremely lightweight in comparison.
51 | 
52 | The OS sees is a single
53 | user level process requesting and running multiple threads.
54 | Goroutines exists only in the virtual space of go runtime
55 | and not in the OS. A goroutine is created with initial only 2KB of stack size.
56 | The go runtime multiplexes goroutines to operating system (OS) threads.
57 | The cost of creating a Goroutine is tiny compared to a thread.
58 | 
59 | Refer to my cheat sheet
60 | [goroutines & channels](https://github.com/JeffDeCola/my-cheat-sheets/tree/master/software/development/languages/go-cheat-sheet/goroutines-and-channels.md)

17 | 
18 | ## FORMAT SPECIFIERS
19 | 
20 | There is a large list [here](https://golang.org/pkg/fmt/).
21 | 
22 | Default types using %v,
23 | 
24 | * `%v` Default format
25 | * `%+v` Adds field names
26 |   * `%t` boolean
27 |   * `%d` signed
28 |   * `%d` unsigned
29 |   * `%f` or `%g` float
30 |   * `%f` or `%g` complex
31 |   * `%s` string
32 |   * `%p` pointer
33 |   * `%p` channel
34 | 
35 | Common ones,
36 | 
37 | * `%t` boolean
38 | * `%b` integer base 2
39 | * `%d` integer base 10
40 | * `%x` integer base 16
41 | * `%f` float (no exponent)
42 | * `%g` float
43 | * `%g` complex
44 | * `%s` string
45 | * `%p` pointer
46 | * `%p` channel
47 | * `%p` slice - address of 0th element in base 16 notation, with leading 0
48 | * `%T` type
49 | 
50 | As an example,
51 | 
52 | ```go
53 | var myboolean bool = true
54 | var myint int = -33
55 | var myuint32 uint32 = 33
56 | var myfloat32 float32 = 3.1425
57 | var mycomplex64 complex64 = 33.23423432
58 | var mystring string = "Jeff"
59 | var myslice = []string{"jeff", "larry"}
60 | var mymap = map[int]string{1: "cat", 2: "dog"}
61 | mypointer := new(string)
62 | *mypointer = "jeffry"
63 | 
64 | fmt.Printf("myboolean    %v or %t\n", myboolean, myboolean)     // true or true
65 | fmt.Printf("myint        %v or %d\n", myint, myint)             // -33 or -33
66 | fmt.Printf("myuint32     %v or %d\n", myuint32, myuint32)       // 33 or 33
67 | fmt.Printf("myfloat32    %v or %g\n", myfloat32, myfloat32)     // 3.1425 or 3.1425
68 | fmt.Printf("myfloat32    %f or %.2f\n", myfloat32, myfloat32)   //  3.142500 or 3.14
69 | fmt.Printf("mycomplex64  %v or %g\n", mycomplex64, mycomplex64) // (33.234234+0i) or (33.234234+0i)
70 | fmt.Printf("mystring     %v or %s\n", mystring, mystring)       // Jeff or Jeff
71 | fmt.Printf("myslice      %v or %s\n", myslice, myslice)         // [jeff larry] or [jeff larry]
72 | fmt.Printf("myslice      %v or %s\n", myslice[0], myslice[1])   // jeff or larry
73 | fmt.Printf("mymap        %v or %s\n", mymap, mymap[1])          // map[1:cat 2:dog] or cat
74 | fmt.Printf("mypointer    %v or %p\n", mypointer, mypointer)     // 0xc42000e1e0 or 0xc42000e1e0
75 | fmt.Printf("mypointer    %v or %s\n", *mypointer, *mypointer)   // jeffry or jeffry
76 | fmt.Printf("mypointer    %v or %p\n", &mypointer, &mypointer)   // 0xc42000c028 or 0xc42000c028
77 | ```
78 | 
79 | ## ESCAPE SEQUENCES
80 | 
81 | These are really constants, but I put them here because they are mainly used in formatting.
82 | 
83 | Popular ones,
84 | 
85 | * `\n` newline
86 | * `\?` ? character
87 | * `\b` backspace
88 | * `\"` " character
89 |

24 | ## GO GET A PACKAGE AND USE IT
25 | 
26 | You already have the regular go packages.
27 | Lets bring another package to your computer and use it,
28 | 
29 | ```go
30 | go get -u -v github.com/golang/protobuf/protoc-gen-go
31 | ```
32 | 
33 | `-u -v` looks for update and is verbose.
34 | 
35 | The package in now located in your `/src` folder.
36 | 
37 | Now use the package. I know there is a constant
38 | WireStartGroup that is 3. Hence,
39 | 
40 | ```go
41 | import (
42 |     "fmt"
43 |     "github.com/golang/protobuf/proto"
44 | )
45 | 
46 | func main() {
47 |     fmt.Println(proto.WireStartGroup)   // 3
48 | }
49 | ```
50 | 
51 | For some examples of using packages, checkout my repo
52 | [my-go-examples](https://github.com/JeffDeCola/my-go-examples#packages).
53 | 
54 | ## LETS CREATE A CUSTOM PACKAGE
55 | 
56 | Lets create a simple `jeffshapes` package that will,
57 | 
58 | * Get the area and circumference for a circle
59 | 
60 | The code is located in
61 | [my-go-packages](https://github.com/JeffDeCola/my-go-packages#jeffshapes).
62 | 
63 | First get the package,
64 | 
65 | ```bash
66 | go get -u -v github.com/JeffDeCola/my-go-packages/jeffshapes
67 | ```
68 | 
69 | Then import in your code,
70 | 
71 | ```bash
72 | import github.com/JeffDeCola/my-go-packages/jeffshapes
73 | ```

25 | int to float,
26 | 
27 | ```go
28 | i := 33

33 | ## TYPE ASSERTION
34 | 
35 | A type assertion provides access to an interface value's underlying
36 | concrete value,
37 | 
38 | ```go
39 | t := interface.(T)
40 | ```
41 | 
42 | ```go
43 | var j interface{} = "jeff"
44 | s, ok := j.(string)
45 | fmt.Println(s, ok) // Prints jeff true
46 | f, ok := j.(float32)
47 | fmt.Println(f, ok) // Prints 0, false

13 | 
14 | `gotests` automatically generates unit tests.
15 | 
16 | Use `go get` to install and update,
17 | 
18 | ```bash
19 | go get -v -u github.com/cweill/gotests/...
20 | ```
21 | 
22 | This will place binary in `$GOPATH/bin`.
23 | 
24 | Generate test file `filename_test.go`,
25 | 
26 | ```bash
27 | gotests -w -all filename.go
28 | ```
29 | 
30 | * `-w` writes to test file
31 | * `-all` generate test for all functions and methods
32 | 
33 | Run,
34 | 
35 | ```bash
36 | go test -v -cover .

12 | 
13 | ## INSTALL USING A BOOTABLE THUMB DRIVE
14 | 
15 | I got my Ubuntu from
16 | [here](https://ubuntu.com/download/desktop).
17 | 
18 | I created a bootable ubuntu using windows
19 | [rufus](https://rufus.ie/)
20 | (A free application for Windows that can be used to format
21 | and create bootable USB thumb drives)
22 | The MBR partition scheme should work.
23 | 
24 | You may have to enter your bios to change the boot order.
25 | 
26 | ## AN ISSUE I HAD WITH INTEL RST
27 | 
28 | If your computer uses RST (Intel Rapid Storage Technology), you
29 | may need to change to AHCI (Advanced Host Controller Interface).
30 | The **trick is to reinstall Windows with AHCI**.  Don't worry, it's not that hard.
31 | 
32 | First you need two USB thumb drives,
33 | 
34 | * Create a `Windows Recovery Disk` on a USB thumb drive
35 | on the computer you want to dual boot on. Search for `recovery drive`
36 | in Windows and follow the steps
37 | * Create your `bootable Ubuntu USB thumb drive`
38 | using rufus (see above) with the GPT partition scheme
39 | 
40 | Second, depending on your BIOS, you may need to,
41 | 
42 | * Disable `Fastboot`
43 | * Set `Secure Boot` to disabled
44 | * Change Intel Rapid Storage Technology (RST) to AHCI
45 | 
46 | Third, Windows probably won't boot, so put in your Windows Recovery
47 | Drive and do a fresh install.
48 | **Now AHCI is being used, not RST.**  This was the trick.
49 | 
50 | Last, after you have Windows reinstalled (using AHCI),
51 | 
52 | * Put in `bootable Ubuntu USB thumb drive`
53 | * Reboot
54 | * Enter BIOS
55 | * Choose Ubuntu to boot
56 | * Save exit
57 | 
58 | Now you should be able to dual boot install Ubuntu on your rig.  Congrats.

11 | 
12 | ## INSTALL INCONSOLATA FONT
13 | 
14 | As an example, lets install the inconsolata font,
15 | 
16 | Get package,
17 | 
18 | ```bash
19 | sudo apt-get install fonts-inconsolata -y
20 | sudo fc-cache -fv
21 | ```
22 | 
23 | But it doesn’t have everything so Download .tff font from google,
24 | 
25 | ```bash
26 | wget -O ~/Downloads/Open_Sans.zip https://fonts.google.com/download?family=Open%20Sans
27 | wget -O ~/Downloads/Inconsolata.zip https://fonts.google.com/download?family=Inconsolata
28 | ```
29 | 
30 | Unzip and place in fonts folder,
31 | 
32 | ```bash
33 | cd /usr/share/fonts
34 | sudo mkdir googlefonts
35 | sudo chmod -R --reference=opentype googlefonts
36 | cd googlefonts
37 | sudo unzip -d . ~/Downloads/Inconsolata.zip
38 | ```
39 | 
40 | Now register the fonts,
41 | 
42 | ```bash
43 | sudo fc-cache -fv
44 | ```
45 | 
46 | Check you have them,
47 | 
48 | ```bash
49 | find /usr/share/fonts | grep -i inconsolata
50 | fc-list | grep -i inconsolata
51 | fc-match Inconsolata
52 | ```

37 | | **\|& tee -a** |   yes    |   yes    |   yes    |   yes    |   append      |
38 | 
39 | For example,
40 | 
41 | File will contain jeff, but not on terminal,
42 | 
43 | ```bash
44 | echo "jeff" > test.txt
45 | ```
46 | 
47 | On terminal but the file will be empty,
48 | 
49 | ```bash
50 | echo "jeff" 2> test.txt
51 | ```
52 | 
53 | Both on terminal and in the file,
54 | 
55 | ```bash
56 | echo "jeff" | tee test.txt
57 | ```

19 | 
20 | ## OVERVIEW
21 | 
22 | The `ls` that comes with macOS is from `BSD`, and lacks some
23 | of the features of its GNU sibling.
24 | 
25 | Setting `ls` color for linux is
26 | [here](https://github.com/JeffDeCola/my-cheat-sheets/tree/master/software/development/operating-systems/linux/ls_colors-cheat-sheet).
27 | 
28 | ## BSD - SET LSCOLORS ENV VARIABLE
29 | 
30 | Its pretty simple,
31 | 
32 | ```bash
33 | export CLICOLOR=1
34 | export LSCOLORS=ExGxBxDxCxEgEdxbxgxcxd
35 | ```
36 | 
37 | For grep add,
38 | 
39 | ```bash
40 | export GREP_OPTIONS='--color=always'
41 | export GREP_COLOR='01;31'
42 | ```
43 | 
44 | A limitation is that you can't set different file
45 | extensions like .gz.
46 | 
47 | ## BSD - SETTINGS
48 | 
49 | Settings for LSCOLORS.

17 | 
18 | ## WSL2 NOW COMES WITH WSLG
19 | 
20 | wsl2 now comes with it's own xserver `wslg`.
21 | 
22 | ### DISPLAY=:0
23 | 
24 | Set your display to,
25 | 
26 | ```txt
27 | export DISPLAY=:0
28 | ```
29 | 
30 | ### SCALING
31 | 
32 | If you want to scale the display, create a `.wslgconfig` file in your
33 | windows user directory.
34 | 
35 | ```text
36 | [system-distro-env]
37 | ;WESTON_RDP_HI_DPI_SCALING=false
38 | WESTON_RDP_FRACTIONAL_HI_DPI_SCALING=true
39 | WESTON_RDP_DEBUG_DESKTOP_SCALING_FACTOR=200
40 | ```
41 | 
42 | Restart wsl in powershell to use the new settings,
43 | 
44 | ```bash
45 | wsl --shutdown
46 | ```
47 | 
48 | ## USING YOU OWN XSERVER
49 | 
50 | You can also use your won xserver such as VcXsrv.
51 | 
52 | ### STEP 1: SET DISPLAY VARIABLE
53 | 
54 | We need to set the DISPLAY variable to X.X.X.X:0 for GTKwave.
55 | 
56 | Add to .bashrc,
57 | 
58 | ```bash
59 | export DISPLAY=$(awk '/nameserver / {print $2; exit}' /etc/resolv.conf 2>/dev/null):0
60 | export LIBGL_ALWAYS_INDIRECT=1
61 | ```
62 | 
63 | The end result will be something like DISPLAY=172.X.X.X:0
64 | 
65 | ### STEP 2: SET INBOUND FIREWALL RULE
66 | 
67 | Set an inbound firewall rule to allow the
68 | X11 on port 6000 with scope 172.16.0.0/12.
69 | 
70 | ### STEP 3: INSTALL XSERVER FOR WINDOWS
71 | 
72 | Windows does not come with an xserver, so you must get one.
73 | 
74 | VcXsrv is a free Windows X Server. Download from
75 | [here](https://sourceforge.net/projects/vcxsrv/).
76 | 
77 | When configuring disable access control.
78 | 
79 | Make sure this programs firewall rule is both for private
80 | and public networks.

17 | 
18 | ## WHAT IS YOUTUBE'S CONTENT-ID SYSTEM
19 | 
20 | Content owners or Administrators will have access to their assets:
21 | 
22 | * Metadata
23 | * Ownership Information
24 | * Policy Information
25 | * Create New Assets
26 | * Manage Assets
27 | * Claim Content
28 | * Upload Videos
29 | 
30 | Furthermore, by combining `Youtube Content ID` with `Youtube Data API`
31 | and `Youtube Player API`, you can enable your app to upload, manage and play videos.
32 | 
33 | ## YOUTUBE CONTENT PARTNER - ALLOWS ACCESS
34 | 
35 | To use the content-id api, the user must be a Youtube Content Partner.
36 | 
37 | If you are a Youtube Content Partner you can access the
38 | Content ID Online Interface [here](https://www.youtube.com/content_id?o=U).
39 | 
40 | You will also see this api listed in google's API Service Manager
41 | [here](https://console.developers.google.com/apis/dashboard)
42 | 
43 | ## AUTHENTIFICATION - CONTENT-ID USES OAuth 2.0
44 | 
45 | Google uses many ways to authenticate, such as `API Key`,  `Service Account` or
46 | `OAuth 2.0 Client ID`.
47 | 
48 | YouTube's Content ID uses `OAuth 2.0 Client ID` for authentication.
49 | 
50 | Refer to [OAuth 2.0 Authorization Cheat Sheet](https://github.com/JeffDeCola/my-cheat-sheets/tree/master/software/development/software-architectures/authorization/OAuth-2.0-authorization-cheat-sheet)
51 | for how to authenticate.

22 |   **<- YOU ARE HERE**
23 | 
24 | ## OAuth 2.0 SERVICE ACCOUNT FLOW - TO AUTHORIZE API CALLS
25 | 
26 | A Service Account is a Google Account that can be used to
27 | authorize API calls without ANY user interaction. It's Server-to-Server.
28 | 
29 | For the OAuth 2.0 flow for Service Accounts, the steps for authenticating
30 | and authorizing access to API resources do not take place in a web browser
31 | 
32 | Your application can use the OAuth 2.0 flow for Service Accounts
33 | such as the YouTube Content ID API or google Cloud Storage API.
34 | 
35 | ## CREATE OAuth 2.0 CLIENT ID & SECRET
36 | 
37 | To create an `OAuth 2.0 Client ID` goto credentials page
38 | [here](https://console.developers.google.com/projectselector/apis/credentials)
39 | and select create credentials.
40 | 
41 | Create a OAuth 2.0 client IDs for a `web application`.
42 | 
43 | You will now have a Client ID and a Secret.  Obviously, keep this in a safe place.
44 | 
45 | ## HIGH-LEVEL VIEW
46 | 
47 | The following diagram illustrates how everything fits together. To
48 | access a users info they must be in your g-suite domain.

20 | ## OVERVIEW
21 | 
22 | A blockchain is a structure for storing data in which groups of
23 | valid transactions, called blocks, form a chronological chain,
24 | with each block cryptographically linked to the previous one.
25 | 
26 | * The data comes in blocks
27 | * Blocks are chained together and this makes their data immutable
28 | * When a block of data is chained to the other blocks,
29 |   its data can never be changed again
30 | * It is publicly available to anyone who wants to
31 |   see it
32 | 
33 | ## HOW DOES IT WORK
34 | 
35 | ### STEP 1 - A BLOCK OF DATA
36 | 
37 | * A block mainly has immutable data in it.
38 | 
39 | ### STEP 2 - BLOCK HASH
40 | 
41 | * Every block gets a unique digital signature (a hash)
42 |   that corresponds to exactly the data in that block
43 | * The hash has a few characters at the beginning
44 |   that are unique (e.g. 000).
45 | 
46 | ### STEP 3 - CHAIN BLOCKS TOGETHER
47 | 
48 | * Chain blocks together with the previous blocks hash
49 | * Hence block 2 has the has of block 1 and using it for its hash
50 | * Once data has been added to the blockchain, it can never be changed
51 | 
52 | Here is an illustration of a chain of blocks,
53 | 
54 | ![IMAGE - blockchain-data-hash - IMAGE](../../../../../docs/pics/software/development/blockchain-data-hash.svg)
55 | 
56 | Now imagine if the data in block 1 is altered, even by 1 bit.
57 | That would create a new hash.
58 | That would obviously break the chain and would be rejected.
59 | 
60 | ### STEP 4 - MINING - FINDING THE NONCE
61 | 
62 | When adding a block we have three things,
63 | 
64 | * The data
65 | * The previous blocks hash
66 | * A nonce (a random info to mine)
67 | 
68 | The goal is to find a nonce that will result in the
69 | hash to have that unique number (e.g. 000) at
70 | the start of the hash.
71 | 
72 | ![IMAGE - blockchain-with-mining-data-hash-nonce - IMAGE](../../../../../docs/pics/software/development/blockchain-with-mining-data-hash-nonce.svg)
73 | 
74 | ## WHY IS THIS IMMUTABLE - WHY DO WE ADD BLOCKS
75 | 
76 | It is almost impossible to go back in the chain and change anything.
77 | The amount of computation power is virtually infinite.
78 | 
79 | By adding new blocks you keep the chain going, hence
80 | bad people can't start changing the data because they have to
81 | recalculate all the blocks.

19 | ## SYNCHRONOUS AND ASYNCHRONOUS COMMUNICATION
20 | 
21 | Synchronous and asynchronous communication really depends on
22 | what you're referring too. For example, if you have a uni-directional
23 | communication and you are referring to the data transfer. Or if it
24 | a bi-directional communication and you're referring to
25 | the reply.
26 | 
27 | Here is a high-level view,
28 | 
29 | * Synchronous – The client expects a timely response and might
30 |   even block while it waits
31 | * Asynchronous – The client doesn’t block while waiting for a response,
32 |   and the response, if any, may not be immediate

28 | Cryptography is the art of changing a message from a readable format,
29 | referred to as `plaintext`, into an unreadable one, or `ciphertext`.
30 | 
31 | Asymmetric cryptography uses two separate keys,
32 | 
33 | * A public key is used to encrypt the messages
34 | * A private key is used to then decrypt the message
35 | 
36 | This is used all over the web for ssl, tls, pgp, ssh, etc...

32 | ## NATS
33 | 
34 | NATS is a Message BUS.
35 | Fundamentally NATS is about publishing and listening for messages.
36 | The official NATS server was `gnatsd`
37 | but renamed to `nats-server` for the v2.0.0.release.
38 | 
39 | ## INSTALL A NATS SERVER (nats-server)
40 | 
41 | There are many ways to install,
42 | 
43 | 1. NATS Docker image
44 | 1. Get the binaries
45 | 1. Use the public NATS server nats://demo.nats.io:4222
46 | 1. Build from source
47 | 1. Package Manager
48 | 
49 | MacOS install,
50 | 
51 | ```bash
52 | brew install nats-server
53 | ```
54 | 
55 | Linux Install release build,
56 | 
57 | ```bash
58 | NATS_VER=2.0.4
59 | curl -L https://github.com/nats-io/nats-server/releases/download/v$NATS_VER/nats-server-v$NATS_VER-linux-amd64.zip -o nats-server.zip
60 | unzip nats-server.zip -d nats-server
61 | sudo cp nats-server/nats-server-v$NATS_VER-linux-amd64/nats-server /usr/local/bin/.
62 | rm nats-server.zip
63 | rm -r nats-server
64 | ```
65 | 
66 | Raspberry pi, hummingboard, build from source,
67 | 
68 | ```bash
69 | GO111MODULE=on go get github.com/nats-io/nats-server/v2
70 | ```
71 | 
72 | check,
73 | 
74 | ```bash
75 | nats-server -v
76 | ```
77 | 
78 | ## START NATS (nat-server)
79 | 
80 | For the default of `0.0.0.0:4222` (security is disabled),
81 | 
82 | ```bash
83 | nats-server
84 | nats-server -DV -p 4222 -a 127.0.0.1
85 | ```
86 | 
87 | Where -DV is both debug and trace log.
88 | 
89 | The NATS server listens for client connections on TCP Port 4222.
90 | 
91 | ## INSTALL NATS GO CLIENT LIBRARY
92 | 
93 | ```go
94 | go get -v -u github.com/nats-io/nats.go/
95 | ```

21 | 
22 | ## INSTALL
23 | 
24 | Get vagrant for Windows [here](https://www.vagrantup.com).
25 | 
26 | Search for a concourse vagrant file
27 | [here](https://app.vagrantup.com/boxes/search).
28 | This [one](https://app.vagrantup.com/concourse/boxes/lite) works,
29 | but is in older version of concourse.
30 | 
31 | To run your vagrant box, enter vagrant directory, and from the
32 | Windows cmd prompt type,
33 | 
34 | ```bash
35 | vagrant up
36 | ```
37 | 
38 | To upgrade vagrant box (will destroy current pipelines).
39 | 
40 | ```bash
41 | vagrant box update --box concourse/lite     # gets the newest Vagrant box
42 | vagrant box prune                           # remove the old Vagrant boxes
43 | vagrant up
44 | ```
45 | 
46 | Reinstall the new `fly.exe`.
47 | 
48 | ## BRIDGE CONCOURSE NETWORK TO HOME LAN (198.168.1.x)
49 | 
50 | Add in Vagrantfile,
51 | 
52 | ```txt
53 | config.vm.network "public_network", bridge: 'Intel(R) I210 Gigabit
54 | Network Connection', use_dhcp_assigned_default_route: true
55 | ```
56 | 
57 | Or you could make this change in Virtualbox.
58 | 
59 | Instead of NATS, you use a bridged adapter,
60 | 
61 | ```txt
62 | Settings -> Network - Adapter -> Bridged Adapter
63 | ```
64 | 
65 | Either way, your router (on the host machine's network) will choose an
66 | IP for you.  You can go into that router to save the
67 | IP based on the mac address if you would like.
68 | 
69 | Also, do not set your machine with a static IP.
70 | Let your router assign one.

22 | ## INSTALL
23 | 
24 | This is out of the scope of this cheat sheet.
25 | I used a vagrant file.
26 | 
27 | ## OVERVIEW
28 | 
29 | Deploy, run and scale docker containers easily
30 | with native support.
31 | 
32 | Mesos provides resource management and scheduling
33 | while a framework such as marathon provides
34 | scheduling and execution.
35 | 
36 | There are many types of frameworks that a designed to do
37 | different things such as data storage, or processing.
38 | Marathon is design to keep an app running forever.
39 | 
40 | ## MARATHON .JSON FILE
41 | 
42 | This is sent to marathon to get the docker container.
43 | 
44 | As an example,
45 | 
46 | ```json
47 | {
48 |     "id": "hello-go-deploy-marathon-long-run",
49 |     "cpus": 0.1,
50 |     "mem": 4.0,
51 |     "container": {
52 |         "type": "DOCKER",
53 |         "docker": {
54 |             "forcePullImage": true,
55 |             "image": "jeffdecola/hello-go-deploy-marathon:latest",
56 |             "network": "BRIDGE",
57 |             "portMappings": [{
58 |                 "containerPort": 8080,
59 |                 "hostPort": 0
60 |             }]
61 |         }
62 |     }
63 | }
64 | ```
65 | 
66 | ## DEPLOY DOCKER CONTAINER
67 | 
68 | To deploy your app, send the json file to marathon,
69 | 
70 | ```bash
71 | curl -X PUT http://10.141.141.10:8080/v2/apps/jeffAPP \
72 |     -d @app.json -H "Content-type: application/json"

23 | ## OVERVIEW (MESOS, MESOSPHERE & MESOS DC/OS)
24 | 
25 | `Mesos` is a project by Apache that gives you the
26 | ability to run both containerized, and non-containerized
27 | workloads in a distributed manner.
28 | Mesos is complicated and hard to manage, so mesosphere
29 | tries to make mesos into something understandable.
30 | 
31 | `Mesosphere` has a marathon “plugin” to mesos, which is an
32 | easy way to manage container orchestration over mesos.
33 | 
34 | `Mesos DC/OS` (Data Center Operating System) simplifies mesos
35 | even further and allows you to deploy your own mesos cluster,
36 | with marathon, in a matter of minutes.
37 | 
38 | ## INSTALL
39 | 
40 | This is out of the scope of this cheat sheet.
41 | I used a vagrant file.
42 | 
43 | ## FRAMEWORK - MARATHON
44 | 
45 | Mesos provides resource management and scheduling
46 | while a framework such as marathon provides
47 | scheduling and execution.
48 | 
49 | There are many types of frameworks that a designed to do different
50 | things such as data storage, or processing.
51 | Marathon is design to keep an app running forever.

12 | 
13 | ## OVERVIEW
14 | 
15 | I personally do not like this way since it requires a

17 | 
18 | Use

20 | instead.
21 | 
22 | But for completeness, as a high level overview,
23 | 
24 | * Start up an `instance` using an existing `image`.
25 |   As a side note, no instance template or instance group are needed.
26 | * ssh into your new instance and add whatever you want -
27 |   installs, docker, etc...(this is a little ugly).
28 | * When you're happy, stop the `instance` so that it can shut down
29 |   and stop writing the data to the `persistent boot disk`.
30 | * Create `image` from the `persistent boot disk`.
31 | 
32 | To perform the above steps, you can use the console/ssh or write scripts using `gcloud`.
33 | 
34 | Again, I understand I didn't get into details and didn't write
35 | any scripts to do this.  Its because I find
36 | [create custom image using packer](https://github.com/JeffDeCola/my-cheat-sheets/tree/master/software/service-architectures/infrastructure-as-a-service/google-compute-engine-cheat-sheet/google-compute-engine-create-image-packer.md)
37 | much more elegant.

19 | 
20 | ## WHY DO YOU NEED THIS
21 | 
22 | I use it for the `encrypted repos` hosted at keybase.io.
23 | It is not like github where you can goto the website and do PR, etc.
24 | Its just a place to keep a repo that is encrypted end-to-end.
25 | 
26 | Hence this program is connected to your keybase account
27 | and will encrypt your data before it is sent to the repo.
28 | 
29 | Refer to your keybase app to create a repo and then just use normal git.
30 | 
31 | ## INSTALL
32 | 
33 | The easiest way to install is being going to the website
34 | [here](https://keybase.io/).
35 | 
36 | ### LINUX
37 | 
38 | ```bash
39 | curl --remote-name https://prerelease.keybase.io/keybase_amd64.deb
40 | sudo apt install ./keybase_amd64.deb
41 | run_keybase
42 | ```
43 | 
44 | Check,
45 | 
46 | ```bash
47 | keybase version
48 | ```
49 | 
50 | ### GO
51 | 
52 | ```bash
53 | go get -u -v github.com/keybase/client/go/keybase
54 | go install -tags production github.com/keybase/client/go/keybase
55 | ```
56 | 
57 | Run service,
58 | 
59 | ```bash
60 | keybase service &
61 | ```
62 | 
63 | Run client,
64 | 
65 | ```bash
66 | keybase login
67 | ```
68 | 
69 | Check,
70 | 
71 | ```bash
72 | keybase version
73 | ```
74 | 
75 | Install kbfsfuse,
76 | 
77 | ```bash
78 | cd $GOPATH/src/github.com/keybase/client/go/kbfs/kbfsfuse
79 | go install
80 | ```
81 | 
82 | Install git-remote-keybase,
83 | 
84 | ```bash
85 | cd $GOPATH/src/github.com/keybase/client/go/kbfs/kbfsgit/git-remote-keybase
86 | go install
