When investigating some geometric problem, there are a number of questions you might want to ask yourself to narrow down the scope of the question. How many dimensions are you dealing with? Is it 2d, 3d, a specific number of higher dimensions, or without respect to dimensionality? In case of a 2...

Overall you have two ways to monitor processes at linux host Static monitoring Most widely used command is ps (i.e., process status) command is used to provide information about the currently running processes, including their process identification numbers (PIDs).

To get general statistics about main components of Linux family of stat commands are extremely useful CPU To get processors related statistics you can use mpstat command but with some options it will provide better visibility: $ mpstat 2 10 Memory We all know command free to show amount of (r...

One can describe a line in arbitrary dimensions as X = A + t*D where A and D are both vectors of suitably many dimensions. So in 2d this would be x = Ax + t*Dx y = Ay + t*Dy Now as t assumes any real value, this equation will produce all points along the line. The representation is not uniq...

Given a pair of points A and B in a vector space of arbitrary dimension, one can describe the line between them as X = A + t*(B - A) = (1 - t)*A + t*B so in 2d this would be x = Ax + t*(Bx - Ax) = (1 - t)*Ax + t*Bx y = Ay + t*(By - Ay) = (1 - t)*Ay + t*By As t assumes any real value, this w...

A line in the plane can be described as a*x + b*y + c = 0 This uses a three-element parameter vector [a, b, c] to describe the line. Sometimes the constant term c is moved to the right hand side of the equation instead. The representation is not unique, since the length of that vector is arbitra...

A DTD is referred to as an internal DTD if elements are declared within the XML files. To reference it as internal DTD, standalone attribute in XML declaration must be set to yes. An XML that describes a note that contains property to, from and message along with internal DTD will look like: <...

In external DTD elements are declared outside the XML file. They are accessed by specifying the system attributes which may be either the legal .dtd file or a valid URL. To reference it as external DTD, the standalone attribute in the XML declaration must be set as no. An XML that describes a note ...

The currency pipe allows you to work with you data as regular numbers but display it with standard currency formatting (currency symbol, decimal places, etc.) in the view. @Component({ selector: 'currency-pipe', template: `<div> <p>A: {{myMoney | currency:'USD':false}}</p&...

SSL Certificates use something called public key cryptography.We need to use Https instead of Http because of keeping data secure between servers and improving customer trust. To enable this option in grails, we have to run our app differently. The command below: grails run-app -https

var alertResult = await DisplayAlert("Alert Title", Alert Message, null, "OK"); if(!alertResult) { //do your stuff. } Here we will get Ok click action.

Sometimes it is required to implement Enum on your own. E.g. there is no clear way to extend other enums. Custom implementation allows this: class Enum { constructor(protected value: string) {} public toString() { return String(this.value); } public is(value: Enum | string) { ...

Online Books These are books that are freely accessible online. Practical Common Lisp by Peter Seibel is a good introduction to CL for experienced programmers, which tries to highlight from the very beginning what makes CL different to other languages. Common Lisp: A Gentle Introduction to Symb...
