conventions

I've seen these two things lately and I'm a bit confused. var blah = new MyClass() { Name = "hello" } and var blah = new MyClass { Name = "hello" } Whats the difference? and why do they both work? Update: Does this mean that if i have something in a constructor which does some computation that i would have to call the first one?? As far as I know, they're exactly equivalent. The C# specification (or at least Microsoft's implementation of it) allows you to omit the () when using the default constructor (no parameters) as long as you're using curly brackets (i.e. the syntax for object

I was using Visual Studio for a long time, but it was becoming too complicated to maintain. Now I tried to move to VS Code, but it throws a number of PyLint error messages that don't make sense to me (and the program still works as expected). These errors happen primarily with Python code generated from a GoogleProtoBuf structure. For example: from lbsnstructure.lbsnstructure_pb2 import lbsnPost def geoaccuracy_within_threshold(post_geoaccuracy, min_geoaccuracy): """Checks if geoaccuracy is within or below threshhold defined""" if min_geoaccuracy == lbsnPost.LATLNG: allowed_geoaccuracies =

What's the best way to indicate a function uses the 'arguments' object? This is obviously opinion based but are there any conventions? When would it be better to use an array of arguments? Some examples: // Function takes n arguments and makes them pretty. function manyArgs() { for (var i = 0; i < arguments.length; i++) console.log(arguments[i]); } function manyArgs( /* n1 , n2, ... */ ) function manyArgs(n1 /*, n2, ... */ ) function manyArgs(argArray) // Using ES6 syntax ... var foo = function(/*...args*/){ // shim Array.from, then var args = Array.from(arguments); // or var args = [].slice

In Node.js, should I use errors for flow control, or should I use them more like exceptions? I'm writing an authentication controller and some unit tests in Sails.js, and currently, my registration method checks to see if a user with the same username exists. If a user already exists with the username, my model method calls its callback arguments with a new Error object, like so: Model: exists: function (options, cb) { User.findOne({ where: { username: typeof options === 'Object' && options.username ? options.username : options }, }).exec(function (err, user) { if (err) return cb(err); if

I am planning to share URLs (time limited) for private objects. Is there a way to set custom error pages for 404/403 http responses ? Yes, it's possible, see this announcement . In the Developer guide there is a paragraph about "Custom Error Document Support" where I read the following sentence. You can optionally provide a custom error document with a user-friendly error message and with additional help. You provide this custom error document as part of adding website configuration to your bucket. Amazon S3 returns your custom error document for only the HTTP 4XX class of error codes. How to
