  • How to change address and name of the computer in linux Ubuntu

    - by Byakugan
    I have troubles again after upgrading Linux to version 12.04 - When I try to update progams and files with "apt-get update" it says something like there is no address added to your computer name. So my hostname has name "Marco" and my hosts file has line "127.0.0.1 Marco" So where is problem? Where should I change my name to get it right for updates? Thank you. Before on version 11.10 it was working fine. W: Failed http://en.archive.ubuntu.com/ubuntu/dists/precise-updates/main/i18n/Translation-en Something bad happened in the translation "en.archive.ubuntu.com: http" (-5 - The machine name is not assigned to any address)

  • Have you used nDepend?

    - by Nick Harrison
    Have you Used NDepend? I have often wanted to use it, but never spent the money on it.   I have developed many tools that try to do pieces of what NDepend does, but never with as much success as they reach. Put simply, it is a tool that will allow you to udnerstand and monitor the architecture of your software, and it does it in some pretty amazing ways. One of the most impressive features is something that they call Code Query Language.   It allows you to write queries very similar to SQL to track the performance of various software metrics and use this to identify areas that are out of compliance with your standards and architecture. For instance, once you have analyzed your project, you can write queries such as : SELECT METHODS WHERE IsPublic AND CouldBePrivate  You can also set up such queries to provide warnings if there are records returned.    You can incorporae this into your daily build and compare build against build. There are over 82 metrics included to allow you to view your code in a variety of angles. I have often advocated for a "Code Inventory" database to track the state of software and the ROI on software investments.    This tool alone will take you about 90% of the way there. If you are not using it yet,  I strongly recommend that you do!

  • How to set up wireless access on a Cisco router

    - by Carlos
    Hi, I've set up my 877W according to the configuration listed in this forum post: IPTV over Cisco 877 (It's the working configuration at the bottom of the post) Note that I have an 877W, so it also has a wireless radio. Now, I've gotten the whole setup to work, so IPTV is working, and I can access the internet via the ethernet ports. Now I'm trying to figure out how to allow access via the dot11radio interface. I've gathered that I basically need to create a bridge group, and bridge the radio to the internet VLAN. However, when I add a bridge-group 2 command to VLAN1, it seems to take down the whole internet VLAN. (The IPTV continues to work.) This makes the router itself inaccessible (I've got a laptop, so no serial) and I end up having to reboot the router. Can anyone tell me how to a) Allow wireless access to the internet (preferably with WEP, to match my old router) b) Determine what makes the router inaccessible when I add the new bridge group c) Forward the IPTV traffic onto a machine on my internet VLAN

  • PBX with Fax and Google Voice

    - by Phill Pafford
    Looking to replace/port my home number which I use for mainly faxing for my home business to a PBX server ( Thinking Asterisk or Elastix ). My question is: Does Asterisk/Elastix support Faxing ( Incoming / Outgoing ) Does Asterisk/Elastix support Google Voice Here is what I'm looking to do: Run some sort of PBX software from my own home server that will allow me to use Google Voice for my home number, possibly allow multiple Google voice ( Though I could live with just the one ) and must support Faxing ( Incoming and Outgoing ). Would Asterisk/Elastix support all of this or would you recommend something else for this? Looking to avoid some of the pitfalls that could happen I like Ubuntu if a Linux environment is needed

  • Intel graphic chipset and NVIDIA Geforce GTX560

    - by antoine
    I have an NVIDIA Geforce GTX560 with two video projectors and I would like to use the onboard Intel Graphic Chipset to plug an additional monitor. I saw the question : How can I use both Intel onboard and Nvidia graphics at the same time? but the answer is so short that I was not convinced. My motherboard (GIGABYTE GA-H61M-D2P-B3 (rev. 1.0)) equipped with Intel H61 Chipset allow shared memory between onboard and PCIe cards. And Windows 7 allow me to use the three outputs thanks to Intel's driver. I'm able to use the onboard graphic card but without graphical interface for now. I think i need intel driver for that. But I would like to know if I can setup my displays in xorg.conf with something like : Section "Device" Identifier "Device0" Driver "intel" EndSection Section "Device" Identifier "Device1" Driver "nvidia" EndSection Section "Device" Identifier "Device2" Driver "nvidia" EndSection Does anyone have successfully setup something like that ? Or should I burn my head experimenting it by myself ? Or is there any good reasons to discouraged me to try ? Thanks for your help. Antoine PS : i'm using Ubuntu 10.10 for now, but I could switch to another version. PS2 : i also read this : Use 3 monitors w/built-in intel adapter + two old nvidia PCI cards on 10.10? which doesn't tell me more about the possibilities to use Intel Graphic and Nvidia at the same time EDIT : according to that : Can not get Dual Monitors to work on Different GPUs, I should be able to run two Xserver one on Intel the other on Nvidia. I will try and post the result here.

  • How does one handle sensitive data when using Github and Heroku?

    - by Jonas
    I am not yet accustomed with the way Git works (And wonder if someone besides Linus is ;)). If you use Heroku to host you application, you need to have your code checked in a Git repo. If you work on an open-source project, you are more likely going to share this repo on Github or other Git hosts. Some things should not be checked in the public repo; database passwords, API keys, certificates, etc... But these things still need to be part of the Git repo since you use it to push your code to Heroku. How to work with this use case? Note: I know that Heroku or PHPFog can use server variables to circumvent this problem. My question is more about how to "hide" parts of the code.

  • Windows Despooler Requires Administrator to Print

    - by Software Monkey
    Does anyone know what changes I might need to make to allow restricted users to print using a printer configured for spooling? My Windows XP SP3 system currently requires me to use an Admin account for printing if the print is configured to spool documents before printing. If the printer is configured for direct printing it works for all accounts. This used to work and some months back it just stopped, and I can't pin down why. The printer itself is configured for all uses to have complete authority. My system is locked down for restricted users given them only read authority to the entire file system except their data directories, which is how I have run my systems for years. I assume there may be a directory somewhere that I need to allow users to write to.

  • An alternative to multiple inheritance when creating an abstraction layer?

    - by sebf
    In my project I am creating an abstraction layer for some APIs. The purpose of the layer is to make multi-platform easier, and also to simplify the APIs to the feature set that I need while also providing some functionality, the implementation of which will be unique to each platform. At the moment, I have implemented it by defining and abstract class, which has methods which creates objects that implement interfaces. The abstract class and these interfaces define the capabilities of my abstraction layer. The implementation of these in my layer should of course be arbitrary from the POV view of my application, but I have done it, for my first API, by creating chains of subclasses which add more specific functionality as the features of the APIs they expose become less generic. An example would probably demonstrate this better: //The interface as seen by the application interface IGenericResource { byte[] GetSomeData(); } interface ISpecificResourceOne : IGenericResource { int SomePropertyOfResourceOne {get;} } interface ISpecificResourceTwo : IGenericResource { string SomePropertyOfResourceTwo {get;} } public abstract class MyLayer { ISpecificResourceOne CreateResourceOne(); ISpecificResourceTwo CreateResourceTwo(); void UseResourceOne(ISpecificResourceOne one); void UseResourceTwo(ISpecificResourceTwo two); } //The layer as created in my library public class LowLevelResource : IGenericResource { byte[] GetSomeData() {} } public class ResourceOne : LowLevelResource, ISpecificResourceOne { int SomePropertyOfResourceOne {get{}} } public class ResourceTwo : ResourceOne, ISpecificResourceTwo { string SomePropertyOfResourceTwo {get {}} } public partial class Implementation : MyLayer { override UseResourceOne(ISpecificResourceOne one) { DoStuff((ResourceOne)one); } } As can be seen, I am essentially trying to have two inheritance chains on the same object, but of course I can't do this so I simulate the second version with interfaces. The thing is though, I don't like using interfaces for this; it seems wrong, in my mind an interface defines a contract, any class that implements that interface should be able to be used where that interface is used but here that is clearly not the case because the interfaces are being used to allow an object from the layer to masquerade as something else, without the application needing to have access to its definition. What technique would allow me to define a comprehensive, intuitive collection of objects for an abstraction layer, while their implementation remains independent? (Language is C#)

  • Lubuntu Full Install on USB Drive with Full Disk Encryption and Grub2

    - by vivi
    I apologise for the wall of text, but I want you to scrutinize my thought-process to make sure there's no mistakes and no other way around it: I wish to have a full install of lubuntu with full disk encryption on one of my usb drives. The laptop I would be booting it from also has windows 7. I want to maintain that OS. From what I've read I must place grub2 on the usb drive so that: If I have the usb plugged in, the laptop would start lubuntu (having USB HD in the BIOS Boot options) If I don't have the usb plugged in, it would normally start windows 7. That's exactly what I want it to do. But: If I install from the normal .iso: Clicking "install lubuntu alongside them" would install it onto my normal HD. Clicking "Erase disk and install lunbuntu" would delete all the stuff I have in my HD and install lubuntu on it. Clicking "Something else" would allow me to choose to install lunbuntu and grub2 onto the usb drive, but would not provide it with encryption. So the normal .iso won't work for what I want. Then I found the alternate .iso and this tutorial: It allows me to install lubuntu with all the options I want and gives me the option to choose where to place the grub2! Hopefully there are no flaws in my train of thought. If there aren't, I have a few questions regarding that tutorial: The author says in his case choosing "Yes to install GRUB to your MBR" installed the grub to the usb drive's mbr. I can't have "in his case". I need to be sure that's what it will do, so that it doesn't mess up the windows boot loader. Choosing "no" would open this window and allow to choose where I want to install the grub. Unfortunately I don't understand which option I should type in the box to install it into the usb drive. Would removing my laptop's Hard Drive ensure that the grub is installed onto the usb drive if i picked first option, "yes"? I apologise once again for the wall of text and appreciate any help you guys can offer me.

  • Go/Obj-C style interfaces with ability to extend compiled objects after initial release

    - by Skrylar
    I have a conceptual model for an object system which involves combining Go/Obj-C interfaces/protocols with being able to add virtual methods from any unit, not just the one which defines a class. The idea of this is to allow Ruby-ish open classes so you can take a minimalist approach to library development, and attach on small pieces of functionality as is actually needed by the whole program. Implementation of this involves a table of methods marked virtual in an RTTI table, which system functions are allowed to add to during module initialization. Upon typecasting an object to an interface, a Go-style lookup is done to create a vtable for that particular mapping and pass it off so you can have comparable performance to C/C++. In this case, methods may be added /afterwards/ which were not previously known and these new methods allow newer interfaces to be satisfied; while I like this idea because it seems like it would be very flexible (disregarding the potential for spaghetti code, which can happen with just about any model you use regardless). By wrapping the system calls for binding methods up in a set of clean C-compatible calls, one would also be able to integrate code with shared libraries and retain a decent amount of performance (Go does not do shared linking, and Objective-C does a dynamic lookup on each call.) Is there a valid use-case for this model that would make it worth the extra background plumbing? As much as this Dylan-style extensibility would be nice to have access to, I can't quite bring myself to a use case that would justify the overhead other than "it could make some kinds of code more extensible in future scenarios."

  • Sharing business logic between server-side and client-side of web application?

    - by thoughtpunch
    Quick question concerning shared code/logic in back and front ends of a web application. I have a web application (Rails + heavy JS) that parses metadata from HTML pages fetched via a user supplied URL (think Pinterest or Instapaper). Currently this processing takes place exclusively on the client-side. The code that fetches the URL and parses the DOM is in a fairly large set of JS scripts in our Rails app. Occasionally want to do this processing on the server-side of the app. For example, what if a user supplied a URL but they have JS disabled or have a non-standard compliant browser, etc. Ideally I'd like to be able to process these URLS in Ruby on the back-end (in asynchronous background jobs perhaps) using the same logic that our JS parsers use WITHOUT porting the JS to Ruby. I've looked at systems that allow you to execute JS scripts in the backend like execjs as well as Ruby-to-Javascript compilers like OpalRB that would hopefully allow "write-once, execute many", but I'm not sure that either is the right decision. Whats the best way to avoid business logic duplication for apps that need to do both client-side and server-side processing of similar data?

  • Is there a way to get a larger desktop than the screen?

    - by Cajuntechie
    Is there any freeware out there that will allow me to run the desktop that is larger than the resolution of the screen? My situation: Win XP, Dell Mini 10, iirc- Intel GMA950 I need to use a netbook for one specific web site (with firefox) that doesn't render properly if the screen isn't at least 1024x768. It is a netbook, so the res is 1024x600. Is there anything out there that will allow me to use a 1024x768 desktop on this smaller screen WITHOUT shrinking the desktop to fit. I want to pan around. Thanks! Cajuntechie

  • Kids and programming: ScratchKara

    - by Mike Pagel
    Ever now and then I kept wondering how to share with my kids the excitement of creating something with your computer. Of course, today this is a bit more difficult, as they have seen 3D animation games and well-edited websites. I guess that's why they weren't all that hyped when I found my first computer model at our local recycling facilities (an 8-bit Laser VZ-200 with rubber keys). When I finally got it up and running with an old analog TV set they finally asked whether we could play soccer on it. Needless to say that my showing them how it remembers some BASIC commands and lists and executes them did not make any impression. So the question is for real: How do you get today's kids excited about programming? And just recently I looked again for environments that allow even young kids (mine are 7 and 9 years old now) to do something and have fun. Obviously any real, text-oriented programming language wouldn't work well. To cut it short: Something really nice was built by University of Oldenburg: ScratchKara. It is the perfect mixture of Kara, a simulation of a little ladybug and Scratch, an authoring environment from MIT. ScratchKara allows kids to initially simply explore how the bug moves and turns by pressing the action buttons, then move towards sequencing commands through drag & drop, and eventually end up building algorithms with procedures and functions. Even through it is built for kids and beginners, the environment comes with debugging and refactoring, which I found more than amazing. My kids love it and I have to admit I keep thinking about how to solve a bit more advanced problems with this language, which does not allow you to store any state information (other than your call stack). Yes, I am hooked, too... Once the language is understood you can then move to one of the original Kara versions, where you can define the bug's behavior through finite statemachines, Turing tables, Java and other textual languages. And from there, anything is possible.

  • Why is group write permission ignored in Ubuntu?

    - by NorthPole
    I want my user to have full access to the local Apache root folder, and I also want the Apache user to have full access to the same folder. What I did was create a new group called DevGroup and I added my user and www-data there. Also I changed the permissions to 770 to allow full group access. But now it won't allow me or the Apache user any kind of access to the folder. Here is what I get with ls: drwxrwx--- 12 root DevGroup 4096 Sep 27 17:34 testFolder Which seems perfect but when I try as a user to access the file I get this: var/www$ ls testFolder/ ls: cannot open directory testFolder/: Permission denied Also when I try to access a page in the folder from a browser: [Thu Sep 27 17:47:16 2012] [error] [client 127.0.0.1] PHP Fatal error: Unknown: Failed opening required '/var/www/testFolder/foo.php' (include_path='.:/usr/share/php:/usr/share/pear') in Unknown on line 0 What's the problem and how can I fix it?

  • Software licensing template that gives room for restricting usage to certain industries/uses of software/source

    - by BSara
    *Why this question is not a duplicate of the questions specified as such: I did not ask if there was a license that restricted specific uses and I did not ask if I could rewrite every line of any open source project. I asked very specifically: "Does there exist X? If not, can I Y with Z?". As far as I can tell, the two questions that were specified as duplicates do not answer my specific question. Please remove the duplicate status placed on the question. I'm developing some software that I would like to be "semi" open source. I would like to allow for anyone to use my software/source unless they are using the software/source for certain purposes. For example, I don't want to allow usage of the software/source if it is being used to create, distribute, view or otherwise support pornography, illegal purposes, etc. I'm no lawyer and couldn't ever hope to write a license myself nor do I have to time to figure how to best do this. My question is this: Does there exist a freely available license or a template for a license that I can use to license my software under they conditions explained above just like one can use the Creative Commons licenses? If not, am I allowed to just alter one of Creative Commons licenses to meet my needs?

  • Misconceptions about purely functional languages?

    - by Giorgio
    I often encounter the following statements / arguments: Pure functional programming languages do not allow side effects (and are therefore of little use in practice because any useful program does have side effects, e.g. when it interacts with the external world). Pure functional programming languages do not allow to write a program that maintains state (which makes programming very awkward because in many application you do need state). I am not an expert in functional languages but here is what I have understood about these topics until now. Regarding point 1, you can interact with the environment in purely functional languages but you have to explicitly mark the code (functions) that introduces them (e.g. in Haskell by means of monadic types). Also, AFAIK computing by side effects (destructively updating data) should also be possible (using monadic types?) but is not the preferred way of working. Regarding point 2, AFAIK you can represent state by threading values through several computation steps (in Haskell, again, using monadic types) but I have no practical experience doing this and my understanding is rather vague. So, are the two statements above correct in any sense or are they just misconceptions about purely functional languages? If they are misconceptions, how did they come about? Could you write a (possibly small) code snippet illustrating the Haskell idiomatic way to (1) implement side effects and (2) implement a computation with state?

  • How to exclude a specific URL from basic authentication in Apache?

    - by ripper234
    Two scenarios: Directory I want my entire server to be password-protected, so I included this directory config in my sites-enabled/000-default: <Directory /> Options FollowSymLinks AllowOverride None AuthType Basic AuthName "Restricted Files" AuthUserFile /etc/apache2/passwords Require user someuser </Directory> The question is how can I exclude a specific URL from this? Proxy I found that the above password protection doesn't apply to mod_proxy, so I added this to my proxy.conf: <Proxy *> Order deny,allow Allow from all AuthType Basic AuthName "Restricted Files" AuthUserFile /etc/apache2/passwords Require user someuser </Proxy> How do I exclude a specific proxied URL from the password protection? I tried adding a new segment: <Proxy http://myspecific.url/> AuthType None </Proxy> but that didn't quite do the trick.

  • Having good domain name and using domain aliases ( I use notlong.com)?

    - by Michal P.
    I use only free servers and after creating my website: http://pundaquit.republika.pl I decided to make access to that domain by simple domain name . I decided to use domain alias http://notlong.com/ service and have simple domain name http://pundaquit.notlong.com The second advantage of using alias here was to be independant from my file host which I will have to change. I haven't found a better alias service like notlong, because notlong.com is easy to remember. After that I encounter many problems: * most of forums or social services treat notlong adress as a spam, * Bing so far hvn't accepted http://pundaquit.notlong.com domain and others. Is it another way to have good free domain name? How about the situation when your hosting server will inform you to expire? Only a lasting layer of domain aliases make you independant from the real file hosts.
