• How-To limit user-names in LightDM login-screen when AccountsService is used

  - by David A. Cobb

  I have several "user" names in passwd that don't represent real people, and that should not appear on the LightDM login-screen. The lightdm-gtk-greeter configuration file clearly says that if AccountsService is installed, the program uses that and ignores its owh configureation files. HOWEVER, there is less than nothing for documentation about how to configure AccountsService! Please, can someone tell me how to configure the system so that only an explicitly specified group of users are shown on the greeter? I could uninstall AccountsService. I did that before, but it comes back (dependencies, I suppose). TIA

• Issues while trying to install Xsane

  - by Sebastian

  :) I am sort of new in the world of Linux. I installed Zorin OS and I am very happy with it. My only problem is that I would like to be able to use my scanner. My Kodak printer works fine, but the scanner is not detected; therefore, I am trying to install Xsane. The issue remains, every time that I try to install it, and error message comes up saying; "Package dependencies cannot be resolved" What can I do? thanks!

• How to disable framebuffer in initramfs in 14.04 server?

  - by Blangero

  Recently I'm working on ubuntu 14.04 server. While using plymouth, I have late splash and tried to fix it, I googled and got lots of suggestions on doing this: vi /etc/initramfs-tools/conf.d/splash and add: FRAMEBUFFER=y and update-initramfs -u After doing this, I got no splash at all.So I deleted the FRAMEBUFFER=y and re-update initramfs, splash came back. But after that I installed something, maybe it's remastersys or n86v or their dependencies, or something else, I got splash gone again and according to the boot.log, I think it's due to framebuffer enabled in initramfs again. I tried FRAMBUFFER=n in /etc/initramfs-tools/conf.d/splash but failed. Now I got no splash and still can't get it back. Does anyone know how to disable framebuffer in initramfs? Thanks a lot!

• Are all languages basically the same?

  - by Anirudh

  Recently, i had to understand the design of a small program written in a language i had no idea about (ABAP, if you must know). I could figure it out without too much difficulty. I realize that mastering a new language is a completely different ball game, but purely understanding the intent of code (specifically production standard code, which is not necessarily complex) in any language is straight forward, if you already know a couple of languages (preferably one procedural/OO and one functional). Is this generally true? Are all programming languages made up of similar constructs like loops, conditional statements and message passing between functions? Are there non-esoteric languages that a typical Java/Ruby/Haskell programmer would not be able to make sense of? Do all languages have a common origin?

• design pattern for unit testing?

  - by Maddy.Shik

  I am beginner in developing test cases, and want to follow good patterns for developing test cases rather than following some person or company's specific ideas. Some people don't make test cases and just develop the way their senior have done in their projects. I am facing lot problems like object dependencies (when want to test method which persist A object i have to first persist B object since A is child of B). Please suggest some good books or sites preferably for learning design pattern for unit test cases. Or reference to some good source code or some discussion for Dos and Donts will do wonder. So that i can avoid doing mistakes be learning from experience of others.

• New Paper on the PeopleSoft Interaction Hub-PeopleTools Relationship

  - by Matthew Haavisto

  A new paper has just been published that explains the relationships and dependencies between the PeopleSoft Interaction Hub (formerly the PeopleSoft Applications Portal), and PeopleTools.  This paper will help you understand which versions of the Hub work with which versions of Tools.  The paper contains information on how new customers can install the PeopleSoft Interaction Hub, and existing PeopleSoft Interaction Hub customers can apply PIH 9.1 Feature Pack 1 functionality if they are on an earlier version. It also describes how PeopleSoft Interaction Hub releases are aligned with PeopleTools releases, the general upgrade process within the Feature Pack model, and how customers can expect this to work with subsequent feature packs, maintenance packs, and bundles. You can get the paper from Oracle support.

• How do i clean up my harddrive?

  - by acidzombie24

  Not to long ago i was using only 35% of my HD. Just recently it shot up to 54% and my diskspace is 16gb so thats more then 3gigs that have been taken. From what i remember i failed to build mysql, i install gitolite which required me to build git from source which had a tons of dependencies (i think it was for building docs, i think i saw latex and other packages but i was drozy when i was installing). I suspect that is what is taking the diskspace. Anyways so far i deleted source folders i know i had and ran these commands. What else can i do? (3gigs is mighty) sudo apt-get autoclean sudo deborphan | xargs sudo apt-get -y remove --purge

• Cannot install ia32-libs on a 64 bit Ubuntu installation

  - by Swarnendu Biswas

  I am using a 64-bit installation of Oneiric. I need to install the ia32-libs package to get some applications (evince, adobe reader) to work. For example, adobe reader is giving the following error: error while loading shared libraries: libGL.so.1: cannot open shared object file: No such file or directory. However, I am not able to install it since it is showing a dependency on ia32-libs-multiarch, which in turn is showing a dependency on gstreamer0.10-plugins-good:i386. This in turn depends on few other packages. How can I install these packages safely and still meet all the dependencies.

• Why does qt-creator need to connect to google-analytics?

  - by Nanda

  I just installed qt-creator to work on non-qt C++ projects. The installed version is 2.5.0 (Based on Qt 4.8.2 32-bit) If I click on any of these pages: I get this error: I realized that /etc/hosts file has the following entry: 127.0.0.1 www.google-analytics.com I don't want to remove the entry from the hosts file because it's always been there along with thousands of other similar adservices/porn/malware addresses. I do not intend to say that qt-creator is looking to create problems in my computer, but I am genuinely interested to know why qt-creator needs to connect to google-analytics? Can this be disabled and qt-creator can still be functional?

• First languages with generic programming support

  - by oluies

  Which was the first language with generic programming support, and what was the first major staticly typed language (widely used) with generics support. Generics implement the concept of parameterized types to allow for multiple types. The term generic means "pertaining to or appropriate to large groups of classes." I have seen the following mentions of "first": First-order parametric polymorphism is now a standard element of statically typed programming languages. Starting with System F [20,42] and functional programming lan- guages, the constructs have found their way into mainstream languages such as Java and C#. In these languages, first-order parametric polymorphism is usually called generics. From "Generics of a Higher Kind", Adriaan Moors, Frank Piessens, and Martin Odersky Generic programming is a style of computer programming in which algorithms are written in terms of to-be-specified-later types that are then instantiated when needed for specific types provided as parameters. This approach, pioneered by Ada in 1983 From Wikipedia Generic Programming

• Recording Available: What's New in ETPM v2.3.0?

  - by Wes Curtis

  Our team has published recordings for 'What's New in ETPM v2.3.1?' as well as overviews of features in a number of functional areas. Partners and customers who are considering implementing on or upgrading to recent versions like 2.3.1 have asked for a similar overview of the features available in ETPM v2.3.0 so they have a more complete view of what has been recently released. The What's New in ETPM v2.3.0? recording presents an overview of the features delivered in the ETPM v2.3.0 release. This recording was conducted in an ETPM v2.3.1 environment but the content focuses solely on those features new to ETPM v2.3.0.

• What is the state of the art in OOP?

  - by Ollie Saunders

  I used to do a lot of object-oriented programming and found myself reading up a lot on how to do it well. When C++ was the dominant OOP language there was a very different set of best practices than have emerged since. Some of the newer ideas I know of are BDD, internal DSLs, and the importing of ideas from functional programming. My question is: is there any consensus on the best way to develop object-oriented software today in the more modern languages such as C#, Ruby, and Python? And what are those practices? For instance, I rather like the idea of stateless objects but how many are actually using that in practice? Or, is the state of the art to deemphasize the importance of OOP? This might be the case for some Python programmers but would be difficult for Rubyists.

• Is static universally "evil" for unit testing and if so why does resharper recommend it?

  - by Vaccano

  I have found that there are only 3 ways to unit test (mock/stub) dependencies that are static in C#.NET: Moles TypeMock JustMock Given that two of these are not free and one has not hit release 1.0, mocking static stuff is not too easy. Does that make static methods and such "evil" (in the unit testing sense)? And if so, why does resharper want me to make anything that can be static, static? (Assuming resharper is not also "evil".) Clarification: I am talking about the scenario when you want to unit test a method and that method calls a static method in a different unit/class. By most definitions of unit testing, if you just let the method under test call the static method in the other unit/class then you are not unit testing, you are integration testing. (Useful, but not a unit test.)

• Few GUI problems with minimal install

  - by Toki Tahmid

  I installed a minimal Ubuntu with a complete functional GUI, but facing a few problems. nm-applet's icon won't show in the notification area, but I can connect to wired internet fine. I am not able to configure my wireless or VPN this way. gksu's authentication screen is different from the usual graphical authentication - the screen turns gray as usual, but there are more options like save password for this session or keyring. And most importantly, it won't accept my password no matter what. And lastly, Gwibber seems to install no matter what, but there's not a single package in my knowledge that I installed has anything related to Gwibber. I would welcome any help regarding these three issues. I did not mention what packages I installed, because the list is long, but I will do so if anyone requests. Thank you in advance!

• GeoToolkit Demo Embedded in an Application Framework via Maven

  - by Geertjan

  As a follow on to yesterday's blog entry, here's the equivalent starter application for GeoToolkit (also known as Geotk) on the NetBeans Platform, which ends up looking like this: The above is a border.shp file I found on-line, while here's a USA states shape file rendered in the application: Note that the navigation bar is also included, though that could later be migrated into the menu bar of the NetBeans Platform.  Download the Maven based NetBeans Platform application with GeoToolkit integration here: http://java.net/projects/nb-api-samples/sources/api-samples/show/versions/7.3/tutorials/geospatial/geotoolkit/MyGeospatialSystem It was quite tricky getting this sample together, parts of it, especially the installer, which creates the database, comes from the Puzzle GIS project, while the files come from on-line locations, with the JAI-related dependencies providing problems of their own. But it's definitely a starting point and you now have the basic Maven structure needed for getting started with GeoToolkit in the context of all the services and components provided by the NetBeans Platform.  Many thanks to Johann Sorel for his patience and help.

• How do I switch the Command key and Control key on a MacBook Pro (12.04)?

  - by kalaracey

  I have scoured the web, and I can't seem to get Xmodmap / anything to work properly. I want to swap BOTH my Command keys with my Control key - in essence, inverting what they do currently. How would I do that? I tried xmodmap -e "keycode 133 = Control_L" and corresponding commands for keycodes 134 (right command) and 37 (control left). I even tried these commands, plus xmodmap -pke > ~/.Xmodmap and xmodmap ~/.Xmodmap in .xinitrc. My end goal is I want HUD / Dash to come up when I click control and command to functional control, i.e., control-v is a commond shortcut to paste, i would click command-v

• Why should I use Bower? [closed]

  - by Wil

  I can fully appreciate the benefits of a package manager like Python PIP, Node npm, or Ruby Gems since they're doing much more than adding files to your applications path. Maybe I'm missing the point, or I'm being obtuse, but here are the negatives I can see: Separate step when building a project Separate dependency to install via another package manager (yo dawg) More clutter in the projects root with bower.json and / or .bowerrc Reliance on the registry being up to date, correct, and available Some imports / references to things like images won't work The positives I can see are these: I don't have to download the dependencies manually Optionally install packages as part of scaffolding based on user prompts or the like I'd really like to know of any benefits I'm unaware of, and I should say I'm not trying to be provocative I genuinely want to know.

• More about JuJu cache

  - by koxon

  I would like to know more about JuJu cache. After I start a charm and JuJu provisions a machine for the first time, the charm will be downloaded and all dependencies installed (apt-get, etc). This process can be very long. Once the charm has been build, configured and deployed once, can JuJu provision more instances of the same charm pre-built and configured? I presume that's what the cache is for, but the documentation is not very explicit: https://juju.ubuntu.com/docs/charms-deploying.html How JuJu tracks the state of the charm if it works that way? Thanks Nic

• GLIBC_2.8 not found

  - by Thomas Nilsson

  As a newbie I seem to have messed up my upgrade leaving my system in a very unstable state. I attempted an upgrade from 8.04LTS which ended in an error about libc and kernel upgrades. I tried to upgrade the kernel but am now unsure if that worked, because when I retried my dist-upgrade there was a lot of errors about pre-dependencies and leaving packages un-configured. Now I have a system that answers almost every command with: /lib/libc.so.6: version `GLIBC_2.8' not found (required by /lib/libselinux.so.1) I probably should try a complete re-installation, but I'm investigating if there is any possibility of getting a working glibc so that I at least can have some commands working to ensure that my backups are recent etc. before doing the clean install. not even 'ls' works without saying "glibc_2.8 not found".

• Examples of "Lost art" on software technology/development

  - by mamcx

  With the advent of a new technology, some old ideas - despite been good - are forgotten in the process. I read a lot how some "new" thing was already present in Lisp like 60 years ago, but only recently resurface with other name or on top of another language. Now look like the new old thing is build functional, non-mutable, non-locking-thread stuff... and that make me wonder what have been "lost" in the art of development of software? What ideas are almost forgotten, waiting for resurface? One of my, I remember when I code in foxpro. The idea of have a full stack to develop database apps without impedance mismatch is something I truly miss. In the current languages, I never find another environment that match how easy was develop in fox back them. What else is missing?
