问题 I 'm following a tutorial about JAAS Authentication here and when it shows how to run the example code, says that the compiled class should be launched with a standard option of Java launcher which is -Djava.security.auth.login.config==sample_jaas.config . In this way a system property will be set: java -Djava.security.auth.login.config==sample_jaas.config sample.SampleAcn I did it with this way, but now I want to run the code in NetBeans too. Since NetBeans use Ant I think specifying these

问题 I'm making a content script extension for Google Chrome, it adds functionality to a website's page. I want to add a couple of options, not big deal really, I'd just need two strings (none of which are sensitive user data). From this answer, I assume I need a background page, which I'd rather not add to my extension - I don't want it to gain unnecessary weight. Do I really need a background page, or I could have an options page without it (and which storage could I use)? 回答1: UPDATE As of

问题 I'm developing my first iPhone app, and while implementing user preferences, I have a few questions on how to best implement this. Assume the basic MVC pattern: MainView displaying data stored in a Model object; MainViewController handling the app logic. For the options, I have an OptionsView and an OptionsViewController. A RootViewController handles swapping of the Main and Options views. First of all, what about the options data? Would I want to make an NSOjbect-derived class to store them

问题 This issue pertains specifically to Minecraft, but it is affecting all Java programs that run on my computer. It would seem that something is forcibly setting a _JAVA_OPTIONS environment variable. When I run my server, I have specified to allocate 4 GB of RAM to it with -Xms4G -Xmx4G in the startup batch file. However, when the server runs, It prints "Picked up _JAVA_OPTIONS: -Xms2048M -Xmx2048M" to the console, only allocating 2 GB. I have checked my system settings and there is no _JAVA

问题 I am struggling with the seemingly very simple thing.I have a pandas data frame containing very long string. df = pd.DataFrame({'one' : ['one', 'two', 'This is very long string very long string very long string veryvery long string']}) Now when I try to print the same, I do not see the full string I rather see only part of the string. I tried following options using print(df.iloc[2]) using to_html using to_string One of the stackoverflow answer suggested to increase column width by using

问题 I'm wondering what the -static option on gcc does. I need this option when compiling a certain application, however when I do I get the following error: gcc -static -O3 -o prog prog.c /usr/bin/ld: cannot find -lc collect2: ld returned 1 exit status What needs installation?

问题 Inspired by Stack Overflow question Idomatic batch processing of text in Emacs? I tried out an Emacs shell script with the following headline: #!/usr/bin/emacs --script I put some Emacs Lisp code in it, and saved it as textfile rcat. Since the --script option does not prevent the loading of the site-start file, I had a lot of Loading /etc/emacs/site-start.d/20apel.el (source)... Loading /etc/emacs23/site-start.d/35elib-startup.el (source)... Loading /etc/emacs23/site-start.d/50auctex.el

问题 Having some annoying issues making AJAX calls simply because almost every browser these days is making an OPTIONS call to the server before the actual AJAX call. Since I am using Play! 2.0, is there any easy way to make a wildcard response to any route using the OPTIONS method? For instance, in my routes do something like: OPTIONS /* controllers.Options.responseDef Yes I am aware that the new Play! doesn't have a wildcard built-in, but there needs to be a solution for this since all browsers

问题 According to this: http://www.xmlplease.com/xquery-xhtml "XQuery does not have a standard way of setting the serialization parameters if available. In XQuery we must look up the proper documentation for the XQuery processor to find out what serialization parameters are implemented if any, and how exactly to use them. If available they can normally be set at the command line. Often they can also be used from inside the XQuery document." In Saxon you can write something like declare option
