upgrade

As we all know by now (I hope), Python 3 is slowly beginning to replace Python 2.x. Of course it will be many MANY years before most of the existing code is finally ported, but there are things we can do right now in our version 2.x code to make the switch easier. Obviously taking a look at what's new in 3.x will be helpful, but what are some things we can do right now to make the upcoming conversion more painless (as well as make it easier to output updates to concurrent versions if needed)? I'm specifically thinking about lines we can start our scripts off with that will make earlier

I work on a large C# application (approximately 450,000 lines of code), we constantly have problems with desktop heap and GDI handle leaks. WPF solves these issues, but I don't know what is the best way to upgrade (I expect this is going to take a long time). The application has only a few forms but these can contain many different sets of user-controls which are determined programatically. This is an internal company app so our release cycles are very short (typically 3 week release cycle). Is there some gradual upgrade path or do we have to take the hit in one massive effort? You can start

I'm running Ubuntu 12.04 which comes by default with NumPy 1.6.0 (I have, actually had , Python 2.7.3 installed). As a result of the answer to this question polyfit() got an unexpected keyword argument 'w' , I need to upgrade it. I downloaded the .tar.gz package for the version 1.8.0 from here , unpacked it, moved inside the folder and run the commands: python setup.py build --fcompiler=gnu95 python setup.py install --user as described in the user guide and in this question: Building NumPy 1.7.1 on Ubuntu . This resulted in NumPy no longer loading in Spyder , which now shows the error:

I have created a SQLite database successfully and it works fine. However when the onUpgrade method is called, I'd like to do so without losing data. The app I'm developing is a quiz app. Simply, when the onCreate method is called I create and prepopulate a database with questions, answers etc. The last column is whether they have set the question as a favourite or not. What I would like to do is that when the onUpgrade method is called, I'd like to temporarily save that one column, drop the whole database, recreate it with any edits I've made to old questions and add any new questions then re

We have been using jQuery 1.4.2 in our web application. Recently it was suggested that we upgrade to a newer version. So far we are thinking about upgrading to 1.9.1 as we need to support IE7 and IE8. Our application uses bunch of plugins e.g. fancybox, cookies, tipsy, jcarousel and bunch of others. Plus we have a lot of script files, probably around 50 files. and then some scripts embedded withing the files. I feel like this is going to be a disaster! Does anyone have any advice? We are not set on yet upgrading to 1.9.1. If I want I can convince the managers to upgrade to a different version.

I upgraded Microsoft.AspNetCore from 2.0.3 to 2.0.5 and my WebAPI project, although running successfully locally, fails to start in production (IIS). Everything was fine in production until this upgrade. The error message produced in the log directory is as follows: Error: An assembly specified in the application dependencies manifest (MyProject.WebAPI.deps.json) was not found: package: 'Microsoft.AspNetCore.Mvc.Abstractions', version: '2.0.2' path: 'lib/netstandard2.0/Microsoft.AspNetCore.Mvc.Abstractions.dll' This assembly was expected to be in the local runtime store as the application was

Possible Duplicate: Painless way to install a new version of R? In R, packages are not compatible across upgrades, and must be reinstalled. Is there any way to easily install the same set of packages in the new version as what I had installed in the old version? Edit: I can't easily access the old version of R, since I upgrade via apt.
