   • What are the consequences of accessing the same database from different programs at the same time?

     Top Answer

     Answered Jul 02, 2014 · 4 votes

     MySQL works on an ACID basis: http://en.wikipedia.org/wiki/ACID

     Which means, both clients will be reading the database as if they were the only clients.

     For this to happen each client must start a transaction, which is a single logical unit of work. Within this transaction either all the operations done to the database must be committed or rolled back.

     Different RDBMSs have different defaults for their transaction support. For MySQL, the isolation level is REPEATABLE READ, which means that SELECT statements within the same transaction are consistent with respect to each other.

     How you can verify this:

     Have program1 going start a transaction and through every row and increasing a value, while the other program starts a transaction and goes through the database calculating the sum of the same value for all rows. When they are done, they close their transactions and print out the results. You will notice that both of them read the database as if they were isolated from each other.

     There are whole books written about JDBC. Here are some links that can get you started:

     JDBC Tutorial: http://docs.oracle.com/javase/tutorial/jdbc/

   • What are the examples of attribute directive

     Top Answer

     Answered Jan 01, 2017 · 0 votes

     Directives can be used to manipulate DOM element. It's so useful when you wanna make a custom (third party) directive that can be used by other programmers in your team or world.

     Basically there are three types of directives.

     1) Structural Directive 2) Attribute directives 3) Component Directive(with template)

     1) Structural Directives usually manipulates structure of view/template. Eg. *ngFor

     will generate element according to your list count. *ngIf

     will display/hide view according to passed value.

     eg.

     <p myColor >Color me!</p> //<<< this helps you to grab DOM element using ElementRef and then I'll color it as shown below.-import { Directive, ElementRef, HostListener, Input } from '@angular/core';@Directive({ selector: '[myColor]'})export class HighlightDirective { constructor(private el: ElementRef) { el.nativeElement.style.backgroundColor = 'red'; }}

     here myColor

     is just an attribute directive

     as it is added to the DOM element as an attribute

     but this attribute doesn't accept any value yet.

     Now let's add a value to myColor

     attribute,

     <p [myColor]="color">Highlight me!</p> -

   • What are the Examples of Project Proposal?

     A project proposal is a detailed document that provides vital information about a proposed project. It acts as a guide in terms of conceptualizing, implementing, and managing the project, outlining clearly what objectives are to be achieved at various stages that include the resources required within the stipulated time. Project proposals exist to convince clients, sponsors, or decision-makers about the need for support for a project.

     Components of a Project Proposal

     A standard project proposal is made up of several important elements that offer a detailed description of the proposed plan. While specific requirements may vary based on organizational standards or the nature of the project, the following components are commonly included in project proposals:

     1. Title Page

     • Title of the Project: This should be a very short and specific title that captures the main theme of the project.
     • Organization Name: The organization or the person who submitted the proposal.

   • What are some of the examples of Expressions?

     Expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division.

     • A constant is a fixed numerical value.
     • A variable is a symbol that does not have a fixed value.
     • A constant, a single variable, or a combination of a variable and a constant combined with multiplication or division is defined as a Term.

     Types of Expressions 

     There are three types of expressions: 

     Arithmetic Expression: This is the expression that includes only numbers and mathematical operators such as addition, subtraction, multiplication, division. 

     Example: 80-5 x 2, 20+5, 85 – 25 …

     Fractional Expression: This is the expression that includes fractional numbers and mathematical operators .. 

     Example: 6/4 – 5/2 , 20/10 +25/2 etc 

     Algebraic Expression: This is the expression that Contains variables, numbers, and mathematical operators.

     Example: 3x + 12y , 5x + 5y etc.....

   • What are the safest kinds of authentication for a rtsp video stream? Any examples of URL implementations?

     Top Answer

     Answered Jan 31, 2017 · 2 votes

     Security for your video stream can focus on different areas - one is access/authentication and so long as you are passing the username and password over an encrypted link then this is a relatively standard level of security - having something more like two factor authentication would require a more complex set up which may be overkill for you.

     Another is protecting the video stream itself from being interpreted, copied or redirected - the safest approach is to encrypt the video stream itself if your camera supports this (many good quality security cameras will). Without this, even if you authenticate the user you run the risk of someone being able to view the video stream. It is worth being aware that even if you use SRTP Secure Real Time Transport Protocol, the encryption features are optional so you need to make sure they are enabled for full security.

     A third, and probably less usual concern but one which may be important depending on the application, is verifying that the video feed is actually coming from the camera or source you think it is. The typical approach to this is to have a key or certificate at the camera which it use to 'sign' or identify itself.

    May 1, 2024 · CUI is a precursor of GUI and was used in most primitive computers. Character User Interface is referred to as CUI. Using CUI, commands can be sent to computer programs as one or more lines of text. In CUI-based systems, a user inputs a command that the computer program understands, processes, and outputs a response for the user.
