browser version detection from server side with java

阅读更多关于 browser version detection from server side with java

I saw many posts related to the browser detection, User agent detection etc...I want to detect the version from server side and send appropriate data based on that. I know browsers can mimic version with tools, but that doesn't matter for me. I need the java solution for the exact version detection. NPE Take a look at user-agent-utils . coder247 Here is the code explaining how to do it using user-agent-utils : String userAgent = req.getHeader("user-agent"); UserAgent ua = UserAgent.parseUserAgentString(userAgent); Version browserVersion = ua.getBrowserVersion(); String browserName = ua

How to use multiple versions of Python without uninstallation

阅读更多关于 How to use multiple versions of Python without uninstallation

问题 I am faced with a unique situation, slightly trivial but painful. I need to use Python 2.6.6 because NLTK is not ported to Python 3 (that's what I could gather). In a different code(which am working concurrently), there is a collections counter function which is available only in Python 3 but not in Python 2.6.6. So, each time I switch between the two codes, I need to install & uninstall the versions. That's such a waste of time. Any suggestions on how I specify which version I want to use?

Load class based on SDK version

阅读更多关于 Load class based on SDK version

问题 Is there any way I can load a class based on what version of the OS the phone is running? For example: I made an app which requires 1.6+ Android. Is there a way for me to load one class or the other based on what OS the phone is running? I'm asking this specifically for contacts. The database was changed from 1.6 to 2.0 and the old version doesn't retrieve contacts on the new OS phone. I'd still like to keep my 1.6 requirement, but at the same time I'd like 2.0+ phones to access the contact

How does Maven resolve version conflicts of transitive dependencies ? nearest-wins strategy

阅读更多关于 How does Maven resolve version conflicts of transitive dependencies ? nearest-wins strategy

I just finally got used to not having any Used undeclared or Unused declared dependencies in my projects. Although it is very hard to track Unused declared runtime/test dependencies that are listed in dependency:analyze... One just must write comments to them in pom.xml or otherwise manage them to know that they are needed for testing or runtime. But the way of resolving version conflict is still unclear to me. Regarding transitive dependencies. How does the nearest-wins strategy work exactly? When is one version used over another version ? If you declare the Used undeclared dependency with a

Require minimum version of R package

阅读更多关于 Require minimum version of R package

I just noticed that there's no version argument to R 's require() or library() functions. What do people do when they need to ensure they have at least some minimum version of a package, so that e.g. they know some bug is fixed, or some feature is available, or whatever? I'm aware of the Depends stuff for package authors, but I'm looking for something to use in scripts, interactive environments, org-mode files, code snippets, etc. I am not aware of such a function, but it should be quite easy to make one. You can base it on sessionInfo() or packageVersion() . After loading the packages
