shorthand

I was researching some information on the topic of trial division, and I came across this symbol in Python: //= I got this from here where the code in the example says: n //= p I can't tell what this is supposed to mean, and my research continues to bring poor results in terms of webpages. // is integer division and the n //= p syntax is short for n = n // p except the value n is modified directly if it supports this . When you see an operator followed by an = , that is performing the operation and then assigning it into the variable. For example, x += 2 means x = x + 2 or add 2 to x . The //

I am having a problem with my URL Shorthands in my .htaccess. Namely, everything works fine with this (now old) code... # URL ShortCut Maker. RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_URI} .(.+)$ RewriteRule ^(.) ?open=encyclopedia&letter=$1&term=%1 [B,L,NC] It shows URL correctly as example.com/Modesty (it shows the page as if the URL would be /?open=encyclopedia&letter=m&term=modesty ), but the problem occurs when I enter: example.com/Šanti , or example.com/Đin , or example.com/Žal , example.com/Čakra , or example.com/Ćof ... ...if I enter

In JavaScript ES6 we can create objects where variable names become keys like this: > let a = 'aaa' 'aaa' > let b = 'bbb' 'bbb' > { a, b } { a:"aaa", b:"bbb" } Does Ruby have something equivalent for hashes? Clarification: Obviously this question regards the shorthand notation. I'm looking for {a,b} not {a:a,b:b} . No, there is no such shorthand notation. Chris O'Sullivan Short answer no. Longer answer Shugo Maeda proposed a patch for this in 2015 (you can read the details about this here: https://bugs.ruby-lang.org/issues/11105 ). At the time Matz wasn't into the idea, but might be willing to

What's the best, preferred way of writing if shorthand one-liner such as: expression ? $foo : $bar Plot twist: I need to echo $foo or echo $bar . Any crazy tricks? :) Dave <?=(expression) ? $foo : $bar?> edit: here's a good read for you on the topic edit: more to read echo expression ? $foo : $bar; The ternary operator evaluates to the value of the second expression if the first one evaluates to TRUE , and evaluates to the third expression if the first evaluates to FALSE . To echo one value or the other, just pass the ternary expression to the echo statement. echo expression ? $foo : $bar;

I was referring a video tutorial where the designer used font: 0/0 a; for image replacement, so I get that 0 is the font-size , another 0 is the line-height but designer skips the a part just by saying that's an hack. So what does that a exactly do there? http://nicolasgallagher.com/another-css-image-replacement-technique/ font:0/0 a – a shorthand property that zeros out the font size and line-height. The a value acts as a very short font-family (an idea taken from the BEM implementation of this method). The CSS validator complains that using 0/0 in the shorthand font property is not valid,

I am learning C#, and am learning about making fields private to the class, and using Getters and Setters to expose Methods instead of field values. Are the get; set; in Method 1 and Method 2 equivalent? e.g. is one a shorthand of the other? class Student { // Instance fields private string name; private int mark; // Method 1 public string Name { get; set; } // Method 2 public int Mark { get { return mark; } set { mark = value; } } } Finally, would Method 2 be used when you want to for example perform a calculation before getting or setting a value? e.g. converting value to a percentage or

I'd like to incorporate whatever shorthand techniques there are in my regular coding habits and also be able to read them when I see them in compacted code. Anybody know of a reference page or documentation that outlines techniques? Edit: I had previously mentioned minifiers and it is now clear to me that minifying and efficient JS-typing techniques are two almost-totally-separate concepts. Updated with ECMAScript 2015 (ES6) goodies. See at the bottom. The most common conditional shorthands are: a = a || b // if a is falsy use b as default a || (a = b) // another version of assigning a default
