forward-compatibility

I want to install File::Fetch, which is a core module in Perl 5.12, in my Perl 5.8.9. In general, I want to compile and install future-dated modules in my back-dated Perl because I cannot upgrade my Perl. So I downloaded the module and also its dependencies. It's quite painful following the dependency tree but I'm more concerned about the fact that some of them are core modules. If I install these, my Perl 5.8.9 core will have patches from 5.12. My question is how I can know whether I can safely install the future-dated modules, especially the core modules. Is there a tutorial for this purpose

Imagine you wrote this 10 years ago (before Intel MPX and the bnd0 .. bnd3 registers were even on a roadmap): section .data ; define some globals which are part of an ABI so you can't just rename them global bnd0 ; MPX bound register name conflict bnd0: dd 123 global k0 ; AVX512 mask register name conflict k0: dq 12345 How can you assemble this with a current version of NASM? i.e. Does NASM (or YASM) have forward compatibility with new versions that support new register names? Obviously this is easy to solve with search/replace inside a single file or project. But in theory, you could have a

i have the basic webserver hello world app for nodejs on windows and it works on localhost. But when i test it from the internet it cannot connect. I set up port forwarding in my netgear router. Am i missing a step here to make my nodejs server visible to the outside world? Thanks. var http = require('http'); http.createServer(function (req, res) { res.writeHead(200, {'Content-Type': 'text/plain'}); res.end('Hello World\n'); }).listen(1337, "127.0.0.1"); console.log('Server running at http://127.0.0.1:1337/'); Bryan Boettcher Make sure you listen on 0.0.0.0 instead of 127.0.0.1 127.0.0.1 is a

This is a question in two parts, the first is the most important and concerns now: Are you following the design and evolution of C++11? What blogs, newsgroups, committee papers, and other resources do you follow? Even where you're not using any new features, how have they affected your current choices? What new features are you using now, either in production or otherwise? The second part is a follow-up, concerning the new standard once it is final: Do you expect to use it immediately? What are you doing to prepare for C++11, other than as listed for the previous questions? Obviously, compiler

Google is deprecating Google Cloud messaging in favor of Firebase Cloud Messaging : Firebase Cloud Messaging (FCM) is the new version of GCM. It inherits the reliable and scalable GCM infrastructure, plus new features! See the FAQ to learn more. If you are integrating messaging in a new app, start with FCM. GCM users are strongly recommended to upgrade to FCM, in order to benefit from new FCM features today and in the future. From some tests I made on my servers, the FCM URL ( https://fcm.googleapis.com/fcm/send ) works with GCM projects, and vice-versa - the GCM URL ( https://android

It has generally been the case the Java source code has been forward compatible. Until Java 8, as far as I know, both compiled classes and source have been forward compatible with later JDK/JVM releases. [Update: this is not correct, see comments re 'enum', etc, below.] However, with the addition of default methods in Java 8 this appears to no longer be the case. For example, a library I have been using has an implementation of java.util.List which includes a List<V> sort() . This method returns a copy of the contents of the list sorted. This library, deployed as a jar file dependency, worked
