If you want the full behavior of streams, the best is probably to use: File.open(File::NULL, “w”) Note that File::NULL is new to Ruby 1.9.3; you can use my backports gem: require ‘backports/1.9.3/file/null’ # => Won’t do anything in 1.9.3+ File.open(File::NULL, “w”) # => works even in Ruby 1.8.6 You could also copy the relevant code … Read more
I think you’ll find all you need to know by looking at this question: source of historical stock data I don’t know of any free data feeds other than Yahoo!, but it doesn’t offer tick-by-tick data, it only offers 1 minute intervals with a 15 minute delay. If you want to use an already existing … Read more
The C and C++ standards make no requirements on how things are implemented, just on what the effect of certain operations is. For the <stdio> vs. <iostream> functionality this means that one could wrap the other, both could be essentially the same, or that they are either entirely independent. Technically, using a common implementation would … Read more
Concepts GZIPInputStream is for streams (or files) zipped as gzip (“.gz” extension). It doesn’t have any header information. This class implements a stream filter for reading compressed data in the GZIP file format If you have a real zip file, you have to use ZipFile to open the file, ask for the list of files … Read more
First, InputStreamReader can handle all input streams, not just files. Other examples are network connections, classpath resources and ZIP files. Second, FileReader until Java 11 did not allow you to specify an encoding and instead only used the plaform default encoding, which made it pretty much useless as using it would result in corrupted data … Read more
Let’s say you have an object in which you want to change some properties. One way to do is by changing each property at a time like object.prop1 = x object.prop2 = y and so on. This will go cumbersome if you have more than few properties to change. Then copyWith method comes handy. This … Read more
I had the same problem and apparently is solved now, despite this and some other gdi+ exceptions are very misleading, I found that actually the problem was that the parameter being sent to a Bitmap constructor was not valid. I have this code: using (System.IO.FileStream fs = new System.IO.FileStream(inputImage, System.IO.FileMode.Open, System.IO.FileAccess.ReadWrite)) { try { using … Read more
Try this: https://www.npmjs.com/package/web-streams-polyfill var streams = require(“web-streams-polyfill”); var readable = new streams.ReadableStream; // Or, in ES6 import { ReadableStream } from “web-streams-polyfill”;
There is an example of this sort of thing in encoding/json documentation: package main import ( “encoding/json” “fmt” “log” “strings” ) func main() { const jsonStream = ` [ {“Name”: “Ed”, “Text”: “Knock knock.”}, {“Name”: “Sam”, “Text”: “Who’s there?”}, {“Name”: “Ed”, “Text”: “Go fmt.”}, {“Name”: “Sam”, “Text”: “Go fmt who?”}, {“Name”: “Ed”, “Text”: “Go fmt … Read more
Check the Length property of the stream. Length represents the number of bytes currently in the file. If it is 0, the file is empty.
