  • Can I disable the message line when launching ``screen -RR``

    - by Jimm Chen
    screen -RR is great. It does one of the two thing automatically: If there is any detached screen session, it picks up one can attach to it. If there is no detached screen session(no session yet, or all have been attach to other terminal), it creates a new screen session automatically. I use Windows server Remote Desktop a lot, screen -RR behaves almost the same when a client connects to a remote desktop server. It is natural and I like it. However, when screen -RR determines it should create a new session, it displays a message line at terminal bottom for 5 second. I'd like to suppress this message line because it brings us little benefit. In my opinion, a remote user can always easily distinguish whether he is connected to a resumed session(a piled-up display) or a newly created session(a clean display) from what he sees in the terminal window. So, is there a way to suppress the nag "New screen..." ? Just suppress that very one, not suppress message line globally. My env: opensuse 11.3, GNU screen 4.00.03 (FAU) 23-Oct-06

    I'm considering moving from using Firefox to using Chrome. (I'm on WinXP) Two questions: What is the best way to achieve adblockplus-like functionality on Chrome? Is it possible to save my session when I close the Chrome window so when I open it again I'll see the same tabs?

  • Chrome: Selecting a link by doing search on its text

    - by cool-RR
    I'm trying to use my computer using the keyboard exclusively, without touching the mouse. When browsing the web it can get hard. I use Tab to select links, but there are often dozens of links on a webpage. I can use Chrome's text search (Ctrl-F) to home in on a piece of text in no time; But I can't figure out how to use it to click on a link. For example, let's say there's a link on a webpage with the text "Swedish Furniture". I can easily find it by typing Ctrl-F s w e d, and then Chrome marks the link as found, but is there any way to follow the link after it's found without tabbing through all the links on the page?

  • How to route all subdomains to a single host using mDNS?

    - by John Mee
    I have a development webserver hosting as "myhost.local" which is found using Bonjour/mDNS. The server is running avahi-daemon. The webserver also wants to handle any subdomains of itself. Eg "cat.myhost.local" and "dog.myhost.local" and "guppy.myhost.local". Given that myhost.local is on a dynamic ip address from dhcp, is there still a way to route all requests for the subdomains to myhost.local? I'm starting to think it not currently possible... http://marc.info/?l=freedesktop-avahi&m=119561596630960&w=2 You can do this with the /etc/avahi/hosts file. Alternatively you can use avahi-publish-host-name. No, he cannot. Since he wants to define an alias, not a new hostname. I.e. he only wants to register an A RR, no reverse PTR RR. But if you stick something into /etc/avahi/hosts then it registers both, and detects a collision if the PTR RR is non-unique, which would be the case for an alias.

  • RMI no such object in table, Server communication error

    - by ben-casey
    My goal is to create a Distributed computing program that launches a server and client at the same time. I need it to be able to install on a couple of machines and have all the machines communicating with each other, i.e. Master node and 5 slave nodes all from one application. My problem is that I cannot properly use unicastRef, I'm thinking that it is a problem with launching everything on the same port, is there a better way I am overlooking? this is part of my code (the part that matters) try { RMIServer obj = new RMIServer(); obj.start(5225); } catch (Exception e) { e.printStackTrace(); } try { System.out.println("We are slave's "); Registry rr = LocateRegistry.getRegistry("127.0.0.1", Store.PORT, new RClient()); Call ss = (Call) rr.lookup("FILLER"); System.out.println(ss.getHello()); } catch (Exception e) { e.printStackTrace(); } } this is my main class (above) this is the server class (below) public RMIServer() { } public void start(int port) throws Exception { try { Registry registry = LocateRegistry.createRegistry(port, new RClient(), new RServer()); Call stuff = new Call(); registry.bind("FILLER", stuff); System.out.println("Server ready"); } catch (Exception e) { System.err.println("Server exception: " + e.toString()); e.printStackTrace(); } } I don't know what I am missing or what I am overlooking but the output looks like this. Listen on 5225 Listen on 8776 Server ready We are slave's Listen on 8776 java.rmi.NoSuchObjectException: no such object in table at sun.rmi.transport.StreamRemoteCall.exceptionReceivedFromServer(StreamRemoteCall.java:255) at sun.rmi.transport.StreamRemoteCall.executeCall(StreamRemoteCall.java:233) at sun.rmi.server.UnicastRef.invoke(UnicastRef.java:359) at sun.rmi.registry.RegistryImpl_Stub.lookup(Unknown Source) at Main.main(Main.java:62) line 62 is this ::: Call ss = (Call) rr.lookup("FILLER");

  • Actionscript/Flex - Is it possible to dynamically extend an object, modify functions, add functions

    - by RR
    I know this question might be frowned upon, but actionscript is a dynamic language similar to javascript and in javascript I can take an object from a library written by someone else and dynamically (at runtime) add/remove/modify functions, properties, prototypes etc. this is kind of like dynamically extending an object to make it work with the library it came with as well as another library. Is something like this possible in flex actionscript? I'm thinking it is only possible with classes that are declared 'dynamic' and definitely not possible with classes declared 'final'. What are your thoughts? Any ideas/tricks?

  • Having py2exe include my data files (like include_package_data)

    - by cool-RR
    I have a Python app which includes non-Python data files in some of its subpackages. I've been using the include_package_data option in my setup.py to include all these files automatically when making distributions. It works well. Now I'm starting to use py2exe. I expected it to see that I have include_package_data=True and to include all the files. But it doesn't. It puts only my Python files in the library.zip, so my app doesn't work. How do I make py2exe include my data files?

  • Python unit-testing with nose: Making sequential tests

    - by cool-RR
    I am just learning how to do unit-testing. I'm on Python / nose / Wing IDE. (The project that I'm writing tests for is a simulations framework, and among other things it lets you run simulations both synchronously and asynchronously, and the results of the simulation should be the same in both.) The thing is, I want some of my tests to use simulation results that were created in other tests. For example, synchronous_test calculates a certain simulation in synchronous mode, but then I want to calculate it in asynchronous mode, and check that the results came out the same. How do I structure this? Do I put them all in one test function, or make a separate asynchronous_test? Do I pass these objects from one test function to another? Also, keep in mind that all these tests will run through a test generator, so I can do the tests for each of the simulation packages included with my program.

  • Python: Why can't I use `super` on a class?

    - by cool-RR
    Why can't I use super to get a method of a class's superclass? Example: Python 3.1.3 >>> class A(object): ... def my_method(self): pass >>> class B(A): ... def my_method(self): pass >>> super(B).my_method Traceback (most recent call last): File "<pyshell#2>", line 1, in <module> super(B).my_method AttributeError: 'super' object has no attribute 'my_method' (Of course this is a trivial case where I could just do A.my_method, but I needed this for a case of diamond-inheritance.) According to super's documentation, it seems like what I want should be possible. This is super's documentation: (Emphasis mine) super() - same as super(__class__, <first argument>) super(type) - unbound super object super(type, obj) - bound super object; requires isinstance(obj, type) super(type, type2) - bound super object; requires issubclass(type2, type) [non-relevant examples redacted]

  • wxPython: Sending a signal to several widgets

    - by cool-RR
    I am not even sure how to ask this question. I want something that is like the wxPython event system, but a bit different. I'll try to explain. When there is a certain change in my program (a "tree change", never mind what that is,) I want to send a signal to all the widgets in my program, notifying them that a "tree change" has occurred, and they should change their display in response. How do I do this? It sounds a little bit like wxPython events, but not really, since events don't spread to all widgets, as far as I know. What would be a good way to do this?

  • How to make a Django model fields calculated at runtime?

    - by Anatoly Rr
    I have a model: class Person (models.Model): name = models.CharField () birthday = models.DateField () age = models.IntegerField () I want to make age field to behave like a property: def get_age (self): return (datetime.datetime.now() - self.birthday).days // 365 age = property (get_age) but at the same time I need age to be a true field, so I can find it in Person._meta.fields, and assign attributes to it: age.help_text = "Age of the person", etc. Obviously I cannot just override Person.save() method to calculate and store age in the database, because it inevitably will become wrong later (in fact, it shouldn't be stored in the database at all). Actually, I don't need to have setters now, but a nice solution must have setting feature. Is it possible in Django, or probably there is a more pythonic and djangoic approach to my problem?

  • Having a Python package install itself under a different name

    - by cool-RR
    I'm developing a package called garlicsim. (Website.) The package is intended for Python 2.X, but I am also offerring Python 3 support on a different fork called garlicsim_py3.(1) So both of these packages live side by side on PyPI, and Python 3 users install garlicsim_py3, and Python 2 users install garlicsim. The problem is: When third party modules want to use garlicsim, they should have one package name to refer to, not two. Sure, they can do something like this: try: import garlicsim except ImportError: import garlicsim_py3 as garlicsim But I would prefer not to make the developers of these modules do this. Is there a way that garlicsim_py3 will install itself under the alias garlicsim? What I want is for a Python 3 user to be able to import garlicsim and refer to the module all the time as garlicsim, but that it will really be garlicsim_py3. I know that the Distribute project does something like this: They make it so you can import setuptools and it will be redirected into their code. I have no idea how they do it. Any ideas? (1) I've reached the decision to support Python 3 on a fork instead of in the same code base; It's important for me that the code base will be clean, and I would really not want to introduce compatibilty hacks.

  • PHP DOMElement::getElementsByTagName - Anyway to get just the immediate matching children?

    - by rr
    Hi All, is there a way to retrieve only the immediate children found by a call to DOMElement::getElementsByTagName? For example, I have an XML document that has a category element. That category element has sub category elements (which have the same structure), like: <category> <id>1</id> <name>Top Level Category Name</name> <subCategory> <id>2</id> <name>Sub Category Name</name> </subCategory> ... </category> If I have a DOMElement representing the top level category, $topLevelCategoryElement->getElementsByTagName('id'); will return a list with the nodes for all 'id' elements, where I want just the one from the top level. Any way to do this outside of using XPath?

  • Python: Getting the attribute name that the created object will be given

    - by cool-RR
    Before I ask this, do note: I want this for debugging purposes. I know that this is going to be some bad black magic, but I want to use it just during debugging so I could identify my objects more easily. It's like this. I have some object from class A that creates a few B instances as attributes: class A(object): def __init__(self) self.vanilla_b = B() self.chocolate_b = B() class B(object): def __init__(self): # ... What I want is that in B.__init__, it will figure out the "vanilla_b" or whatever attribute name it was given, and then put that as the .name attribute to this specific B. Then in debugging when I see some B object floating around, I could know which one it is. Is there any way to do this?

  • Having my Python package install shortcuts in Start menu

    - by cool-RR
    I'm making a Python package that gets installed with a setup.py file using setuptools. The package includes a GUI, and when it's installed on a Windows machine, I want the installation to make a folder in "Programs" in the start menu, and make a shortcut there to a pyw script that will start the GUI. (The pyw think works on all platforms, right?) On Mac and Linux, I would like it to put this shortcut in whatever Mac and Linux have that is parallel to the start menu. How do I do this?

  • Python: Hack to call a method on an object that isn't of its class

    - by cool-RR
    Assume you define a class, which has a method which does some complicated processing: class A(object): def my_method(self): # Some complicated processing is done here return self And now you want to use that method on some object from another class entirely. Like, you want to do A.my_method(7). This is what you'd get: TypeError: unbound method my_method() must be called with A instance as first argument (got int instance instead). Now, is there any possibility to hack things so you could call that method on 7? I'd want to avoid moving the function or rewriting it. (Note that the method's logic does depend on self.) One note: I know that some people will want to say, "You're doing it wrong! You're abusing Python! You shouldn't do it!" So yes, I know, this is a terrible terrible thing I want to do. I'm asking if someone knows how to do it, not how to preach to me that I shouldn't do it.
