  • apt-get commands pausing at 'Waiting for headers'

    - by Matt
    I have a VM running Ubuntu Server 9.10 running a basic web server setup. Whenever I run an apt function it will pause for around 1 minute at 'Waiting for headers...'. It will eventually clear through and continue as normal but it is a bit of an annoyance. Everything else on the server seems to run fine. Any ideas?

  • windows - batch moving files to another folder/directory

    - by jdamae
    I am getting an error message to the effect of unable to move files to a single file. I am not trying to do this. What I am trying to do is move files from one folder to another folder (staging) and then deleting the original folder. If you can show me a better way to do this since I am not doing this correctly. Thank you. Here is my .cmd file: Y: move "Y:\ABC_files\*.js" "C:\Documents and Settings\user\Desktop\ABC_Stage\ABC_files\" move "Y:\ABC_files\*.css" "C:\Documents and Settings\user\Desktop\ABC_Stage\ABC_files\" move "Y:\ABC_files\*.png" "C:\Documents and Settings\user\Desktop\ABC_Stage\ABC_files\" move "Y:\ABC_files\*.htm" "C:\Documents and Settings\user\Desktop\ABC_Stage\ABC_files\" move "Y:\ABC_files\*.gif" "C:\Documents and Settings\user\Desktop\ABC_Stage\ABC_files\" move "Y:\ABC.htm "C:\Documents and Settings\user\Desktop\ABC_Stage\" rmdir "Y:\ABC_files" C:\"Program Files"\"App X"\App-IDE.exe -r ABC4.run

  • Desktop directory disappears in gnome-terminal, then appears again, but all files in it are deleted

    - by Ingen
    I am able to see my Desktop and with all its various links and files. But in the terminal when I try to access the Desktop directory: cd ~/Desktop I get: bash: cd: /home/administrator/Desktop: No such file or directory Then I find I am unable to access any of the files on the Desktop when I click on them although the file icons are there. Then the icons disappear after my clicking on them. Then I am able to access the Desktop directory in the terminal but the directory is empty i.e. all the files/folders have been deleted. What's going on? How can I fix this?

  • Why doesn't this batch file work for me?

    - by asdfg
    The following batch file is not woking. @echo off python -c "print('echo text')" %TEMP%\test.bat call %TEMP%\test.bat Can anyone help me with this?. edit: I needed unix eval functionality in windows. I could not find a direct way though. So I redirected the eval string to a temporary batch file and executed it. The temporary batch file was successfully created but calling it did not work in the above case. I noticed that any command after the test.bat creation did not work.

  • Why Netbeans 6.8 remote project (php) uploads all files by default

    - by xaguilars
    Hi I wanted to know if there's some option for disabling Netbeans to upload all files of a recently imported remote (php) project. I always check "Upload files on run", in the project configuration. But when I click on run Netbeans selects all files by default (I modified only some). The file checkboxes cannot be disabled at once and you have to do this one by one (imagine you have 5000 files...). That's annoying. Do you know any solution? thank you

  • Enterprise level Ticketing and inventory system reccomendations [closed]

    - by TrackingSystem
    My company is sort off at a stand still when it comes to our technician ticketing and inventory system. We currently use Numara TrackIt! - which isn't cutting it to say the least. Dell recommended KACE, but it's web based which is what we would like to avoid. We need a good ticketing and inventory system with the following: Server/Client setup Client supports XP/Windows 7 Ent. Web Based as well as Client is a plus Technician ticketing Active Directory integration Inventory System (Asset tag tracking etc/PO tracking) Exchange integrated - when tickets are made you have an option to send to the requester. Something that will scale well Please, if anyone is a Systems Admin or has knowledge regarding use of a great ticketing system please let me know. We have a large international corporation - price honestly isn't an issue. Keep in mind this will be mainly used for technicians to create tickets, enter inventory(track PCS) and possible even an option to track purchase orders. We want an enterprise level ticketing system with these capabilities please help! Thank you.

  • Can I get some help on a javascript project?

    - by HenryOrrin
    I'm learning javascript and I thought it would be fun to build a "simple" calculator. I spent a few hours coding, and implementing the functions, but it only works partially. Can one of you look at my code and try and figure out what's wrong? The Calculator.zip Here's some explanation of the issues: the add(), subtract(), multiply(), and divide() methods work partially, not at all, or don't do as they're supposed to.. sometimes the 0 wont clear when the replaceDisplay() method evaluates the screen. If it helps, I'm also using jquery, so keep that in mind. Thank you!

  • Using (embedding?) wireshark in a C application for sniffing

    - by happy_emi
    I'm writing a C/C++ application which needs (among other things) to sniff packets and save the output in a file. This file will be read and processed by wireshark after a few days, using a LUA script to do some other stuff. My question is for the sniffing part which must be provided by my application. I can see two ways to do this: 1) Fork the wireshark process in background (of course using the command line version) 2) Using wireshark as library: no forking but include stuff like "wireshark.h" and link against libwireshark.so, thus using function calls to do the sniffing. So far I haven't found any documentation about #2 and it seems that #1 is the "right way" to embed sniffing capabilities in my code. Do you think I'm doing he right thing? Does wireshark allow embedding as a library?

  • What common programming problems are best solved by using prototypes and closures?

    - by vemv
    As much as I understand both concepts, I can't see how can I take advantage of JavaScript's closures and prototypes aside from using them for creating instantiable and/or encapsulated class-like blocks (which seems more of a workaround than an asset to me) Other JS features such as functions-as-values or logical evaluation of non-booleans are much easier to fall in love with... What common programming problems are best solved by using propotypal inheritance and closures?

  • Is there a quick and practical (hands on) way to learn another programming language?

    - by Tamsin
    Due to rather strange circumstances, I only have until Monday to learn (at least) the basics of PHP and .NET programming. I'm already fairly competent (though there is a lot of room for improvement) in C++ so I feel I have some of the concepts nailed already, but I need to get into the two languages in a bit more depth in a very short time frame. Unfortunately I won't have time to get any books so will need to exclusively use online resources, I'm more of a 'do-er' so any way to test my skills in a practical way would be a huge bonus :-)

  • 'Forward-Compatible' Program Design

    - by Jeffrey Kern
    The majority of my questions I've asked here so far on StackOverflow have been how to implement individual concepts and techniques towards developing a software-based NES clone via the XNA environment. The small samples that I've thrown together on my PC work relatively great and everything. Except I hit a brick wall. How do I merge all of these samples together. Having proof-of-concept is amazing, except when you need it to go beyond just that. I now have samples strewn about that I'm trying to merge, some of them incomplete. And now I'm stuck with the chicken-and-the-egg situation of where I would like to incorporate these samples together, to make sure they work, but I cannot without test data. And I don't have tools to create test data, because they'd need to be based off of the individual pieces that need to be put together. In my mind, I'm having nightmares with circular reference. For my sample data, I am hoping to save it in XML and write a specification - and then make sample data by hand - but I'm too paranoid of manually creating an XML file full of incorrect data and blaming it on my code, or vice-versa. It doesn't help that the end-result of my work is graphic-oriented, which makes it interseting how a graphic on the screen can be visualized in XML Nodes. I guess, my question is this: What design patterns and disciplines exist in the coding world that address this type of concern? I've always relied on brute-force coding and restarting a project with a whole new code base in attempts to further along my goals, but I doubt that would be the best way to do so. Within my college career, the majority of my programming was to work on simple projects that came out of a book, or with a given correct data set and a verifyable result. I don't have that, as my own design documents that I am going by could be terribly wrong.

  • Agile language for 2d game prototypes?

    - by instanceofTom
    Occasionally ( read: when my fiancé allows ) I like to prototype different game or game-like ideas I have. Usually I use Java or C# (not xna yet) because they are the languages I have the most practice with. However I would like to learn something more suited to agile development; a language in which it would be easier to knock out quick prototypes. At my job I have recently been working with looser (weak/dynamically typed) languages, specifically python and groovy, and I think something similar would fit what I am looking for. So, my question is: What languages (and framework/engine) would be good for rapidly developing prototypes of 2d game concepts? A few notes: I don't need blazing fast bitcrunching performance. In this case I would strongly prefer ease of development over performance. I'd like to use a language with a healthy community, which to me means a fair amount of maintained 3rd party, libraries. I'd like the language to be cross-platform friendly, I work on a variety of different operating systems and would like something that is portable with minimum effort. I can't imagine myself using a language with out decent options for debugging and editor syntax highlighting support. Note: If you are aware of a Java or C# library/framework that you think streamlines producing game prototypes I open to learning something new for those languages too

  • Help me write my LISP :) LISP environments, Ruby Hashes...

    - by MikeC8
    I'm implementing a rudimentary version of LISP in Ruby just in order to familiarize myself with some concepts. I'm basing my implementation off of Peter Norvig's Lispy (http://norvig.com/lispy.html). There's something I'm missing here though, and I'd appreciate some help... He subclasses Python's dict as follows: class Env(dict): "An environment: a dict of {'var':val} pairs, with an outer Env." def __init__(self, parms=(), args=(), outer=None): self.update(zip(parms,args)) self.outer = outer def find(self, var): "Find the innermost Env where var appears." return self if var in self else self.outer.find(var) He then goes on to explain why he does this rather than just using a dict. However, for some reason, his explanation keeps passing in through my eyes and out through the back of my head. Why not use a dict, and then inside the eval function, when a new "sub-environment" needs to be created, just take the existing dict and update the key/value pairs that need to be updated, and pass that new dict into the next eval? Won't the Python interpreter keep track of the previous "outer" envs? And won't the nature of the recursion ensure that the values are pulled out from "inner" to "outer"? I'm using Ruby, and I tried to implement things this way. Something's not working though, and it might be because of this, or perhaps not. Here's my eval function, env being a regular Hash: def eval(x, env = $global_env) ........ elsif x[0] == "lambda" then ->(*args) { eval(x[2], env.merge(Hash[*x[1].zip(args).flatten(1)])) } ........ end The line that matters of course is the "lambda" one. If there is a difference, what's importantly different between what I'm doing here and what Norvig did with his Env class? If there's no difference, then perhaps someone can enlighten me as to why Norvig uses the Env class. Thanks :)

  • How is a referencing environment generally implemented for closures?

    - by Alexandr Kurilin
    Let's say I have a statically/lexically scoped language with deep binding and I create a closure. The closure will consist of the statements I want executed plus the so called referencing environment, or, to quote this post, the collection of variables which can be used. What does this referencing environment actually look like implementation-wise? I was recently reading about ObjectiveC's implementation of blocks, and the author suggests that behind the scenes you get a copy of all of the variables on the stack and also of all the references to heap objects. The explanation claims that you get a "snapshot" of the referencing environment at the point in time of the closure's creation. Is that more or less what happens, or did I misread that? Is anything done to "freeze" a separate copy of the heap objects, or is it safe to assume that if they get modified between closure creation and the closure executing, the closure will no longer be operating on the original version of the object? If indeed there's copying being made, are there memory usage considerations in situations where one might want to create plenty of closures and store them somewhere? I think that misunderstanding of some of these concepts might lead to tricky issues like the ones Eric Lippert mentions in this blog post. It's interesting because you'd think that it wouldn't make sense to keep a reference to a value type that might be gone by the time the closure is called, but I'm guessing that in C# the compiler will figure out that the variable is needed later and put it into the heap instead. It seems that in most memory-managed languages everything is a reference and thus ObjectiveC is a somewhat unique situation with having to deal with copying what's on the stack.

  • Too late to become a programmer?

    - by Tomas
    Hi, Working in IT for 5 years, I focused on system integration - testing, performance tests and analysis, automation etc. Altough I am working for one of the biggest IT companies, I have the possibility to come up with my own ideas and realize them - for example I have written C# (with SQL backend) bugtracker application with management elements...and I really liked it. I am very creative person but being 25 y/o, I am wondering whether it is too late. I understand the logic of programming but as I was never very good in math I assume I have no chance to become professional programmer in this age. What do you think? Thanks

  • Multiple threads or process with threads

    - by sergiobuj
    Hi, this is for an assignment so I'm not looking for code. I have to simulate a game where each player has turns and needs to 'pay attention' to what's going on. So far, i know I'll need two threads for each player, one that will sleep until the player's turn and the other paying attention. My question is: Should I work each player as a 'fork' and the threads on the fork, or just create some threads for the player and associate them somehow? It's the first time I've worked with concurrency, semaphores and threads so I'm not sure about the good practices and programming style. Thanks!

  • Problem -- My Android "Hello World" App Won't Say 'Hello"

    - by keith
    Hello, I hope that I have come to the right post for a beginner’s question abut Android programming. If not, please feel free to direct me to a better forum. I created a hello world application, and the system generated most of the Android language below. When running the app without the system.out statement, there is no “hello” in the emulator. Then, using the Eclipse tutorial, I read that I can add the system.out.println statement to main. Again the app runs, but there is no output. What am I not understanding here? android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="@string/hello" System.out.println =" Hello world!" / Thank you, Keith
