Fallacies of distributed computing - Wikipedia

Fallacies of distributed computing - Wikipedia, the free encyclopedia:



The fallacies of distributed computing are a set of assumptions that L Peter Deutsch and others at Sun Microsystems originally asserted programmers new to distributedapplications invariably make. These assumptions ultimately prove false, resulting either in the failure of the system, a substantial reduction in system scope, or in large, unplanned expenses required to redesign the system to meet its original goals.

The fallacies are summarized below:

1. The network is reliable.
2. Latency is zero.
3. Bandwidth is infinite.
4. The network is secure.
5. Topology doesn't change.
6. There is one administrator.
7. Transport cost is zero.
8. The network is homogeneous.

akka model

other concurency models
thread
process
futures (no state)
CSP(channels)

actor is persistent (exist even dont do anything )
has internal state
create actors
receive messages and do something
send message
process 1 message at a time (has inbox queue)

w: mutex (lock)
w: race conditions

'Best effort' delivery
at-most-once delivery
message can take arbitrary long time to deliver
no message order garantee

Has address
indentifies an actor or balancer
may represent  proxy forwarder or actor
location transperency
address can be remote
actor can have many addresses

supervision - monitors state of actor (usually other actor)

Supervision tree
address dont change on restart
mailbox is persistent outside of actor
you can kill actor and inbox will be persistent

use cases:
processing pipeline
streaming data
multi-user concurrency
system hight uptime requirements (ericson)
apps with shared state

breaking up the work for many actors

anti-use cases:
performance critical applications
non concurrent
synchronous and stateless

ES6 - Next Javascript

1. Proper tail call (recursion without using caller scope)
tail call - last instruction should be a fun without using caller scope
close call
tail position
max recursion number ~10,000 in ES5

2. Temporal Temp Zone- trows error

3. google traceur-compiler
https://google.github.io/traceur-compiler/demo/repl.html#
there is cmd tool

4. Rest parameters
fun (a, b, ...rest) {
}

4. Spead operator

5. Distructing object
let {name, age} = obj;
fun({name, age}) {}

5.1 Refutable pattern:
let {name:firstName = 'Unknown', age, ?phone} = user;
let ?{name, age, pone} = user;

#irefutable/refutable  - undeclared, undefined

let ?{x:a=1} = undefined
let {?x:a=1} = {}

5.2 Destructing array
in method signature:  fun([a, b, ...rest]) {}
var [a, b, ?c] = [1,2];
var ?[a, c] = [];

6. Arrow functions

Events vs Hooks

Events vs Hooks
[http://programmers.stackexchange.com/questions/237876/what-should-plugins-use-hooks-events-or-something-else]
Hooks loose coupling, event - tight coupling.
Hooks: generic api for all hooks

Hooking - In computer programming, the term hooking covers a range of techniques used to alter or augment the behavior of an operating system, of applications, or of other software components by intercepting function calls or messages or events passed between software components. Code that handles such intercepted function calls, events or messages is called a "hook".

Usefull script for querring all columns from table
SELECT GROUP_CONCAT(COLUMN_NAME) as columns
FROM INFORMATION_SCHEMA.COLUMNS
WHERE table_name = 'customer'

Projects to implement (from ESTI)

1. Create library for reports based on eloquent. and subscr reports
2. Library for auto-reports
3. Library for configs based on qb integration configs: array, yml, mixed, with extension and aggre
4. How to use Laravel event standalone
5. Laravel Events like in qb integration. traits. class::on(), class::fire(); class event subscriber
6. Create class for periods based on carbon: with iteration; formatting; etc

ORM Models field types.

Web2py:
Computed fields: eg wiki page stores html
Virtual fields: lambda that calc field from other fields, analog of Eloquent field modificators

I would call Virtual as calculated.

Eloquent: field modificators geter/setter

var a = 1
    , b = 2
    , sum = a + b

SMS-REST, EMAIL-REST Proxy

Разработать итрерфейс для sms сообщений который будет перенаправляться в REST-full API

Пример:
REST: some-app/books/find?author='Tolstoy'&name='Voina i Mir'
SMS: some-app.books.find author: Tolstoy name: Voina i Mir

- Use google voice as sms gate.

- Bind phone and app and bind incomming phone with user

- Think how to deal with captchas ? Dbc?

- Use YAML as basic syntax for requests and function data schema defenitions.

-  Response will be sent back to the same number in YAML like format

-  User ruby function call syntax:

E.g:  books.store name: Onegin, author: Pushkin, note: This is a very good book. | I realy liked it.

| - new line symbol.

- Possible use of other sms gateways

- Implement the same for email. same sintax. Bind email and

- Sdelat' mobile app

- Try other sms gates

---------

Try to make watsup-rest proxy, facebook-rest proxy, vk-rest proxy

Naming conventions: camelCase versus underscore_case ? what are your thoughts about it? - Programmers Stack Exchange

Source>> stackexchange forum

Both!

I do a lot of development in CakePHP, and I use either CamelCase or $underscored_vars, in the following fashion (even outside CakePHP Projects):

1. filenames — /lowercased_underscored.php Typical, but worth mentioning.
2. classes — class CamelCase extends ParentObject. Note that, when using CamelCase, the initial character is not lowercase. I find camelCase to look really weird.
3. variables — $are_variables_underscored === TRUE;
4. variables that hold instances — $CamelCase = new CamelCase(); //seen it in qb lib but in some languages like ruby everything is a class
5. array keys — $collection['underscored_keys'];
6. constants — I think everyone can agree that constants should be ALL_CAPS_AND_UNDERSCORED.
7. methods — $CamelCase->foo_method_underscored();
8. static methods — CamelCase::just_like_regular_methods();

Some comment: Absolutely agree it bothers me too

have to agree with you, having the first character be lower case drives me crazy! I hate camelCase with a passion. –  HLGEM Jan 6 '11 at 22:00

For programming languages I've used, like Java, Python, C++, I've adopted a clear format:

• ClassNamesArePascalCase
• methodNamesAreCamalCase
• variable_names_are_underscore
• CONSTANT_VARIABLES_ARE_CAPITAL_VARIABLES
• _private_variable_names_are_prefixed_with_an_underscore 
• _PRIVATE_CONSTANT_VARIABLES_ARE_PREFIXED_WITH_AN_UNDERSCORE

=============================

End Source>> stackexchange forum

Another aspect of naming convention is words order:

1. ModelCallReport or CallReportModel

create_date  or  date_create

In PHP main principle of global function creation in having one prefix for same group of functions

It makes it easier to search them

array_map
array_filter

Class methods:
1. call to action notation - first word is action in lower case then camel case
     collection->findFirst(...)
     obj->getName()

2. No action method naming
     App::log()
     DB::table('users')->lastMonth()->get()
   
     I like when lower case part is either proverb or adjective 
     e.g
         lastMonth
         firstElement
         xmlPath

   In method camel case first lwcase word should be specification 
   and last one the most general one eg (object type)

Functions:
1. Javascript style
      function onSaveHanlder

2. PHP/Ruby style
      send_email()

CSS

1. hyphen/slug style
   class="save-btn"
   id="header-container-section" // logic structure: first root element then child then child-child

2. camel
    name="first_name"

3. Bootstrap style (spesialization frist the most general)
   class="btn btn-sm btn-default"  // logic structure: type then size the color

Some people use camel case for css I dond like it 

Summary: 

In general I like ruby naming convention and ruby approach for naming:
  -readability
  -clarity
  -conciseness (short better then long without lose of clarity)

Not sure about snake case methods: I would use it only for properties instead of getter setter
Private fields should be prefixed with underscore :
    eg:  private $_items;
