• How to discriminate vertical from horizontal scroll on Kubuntu/KDE mouse action for switch Desktop

  - by sandroid

  Currently trying out KDE, and I'm a big user of multiple workspaces/desktops while I work. I've noticed that essentially, KDE isn't able (or doesn't bother?) to tell between my mouse's standard vertical scroll, and the left/right scroll that it has. Just FYI, my mouse has a pretty sensitive scroll wheel with no discernible "clicks" so I can easily make my desktop look like it's on crack. Here's what I'd like: vertical scroll does nothing when applied on desktop, but left/right scroll causes me to switch to previous/next desktop. Here's what happens now - per settings for Desktop Settings -- Mouse Actions: Whether I scroll up/down or if I click left/right, I switch desktops. Thanks for your help

• What is a good way to keep track of strings for dictionary lookups?

  - by Justin

  I am working through the Windows 8 app tutorial. They have some code about saving app data like so: private void NameInput_TextChanged(object sender, TextChangedEventArgs e) { Windows.Storage.ApplicationDataContainer roamingSettings = Windows.Storage.ApplicationData.Current.RoamingSettings; roamingSettings.Values["userName"] = nameInput.Text; } I have worked with C# in the past and found that things like using constant string values (like "userName" in this case) for keys could get messy because auto-complete did not work and it was easy to forget if I had made an entry for a setting before and what it was called. So if I don't touch code for awhile I end up accidentally creating multiple entries for the same value that are named slightly differently. Surely there is a better way to keep track of the strings that key to those values. What is a good solution to this problem?

• Searching for a Calendar Application That Meets the Following Criteria

  - by Navarr

  My Step Father is starting his own company, and he gets the wonderful life of having to deal with multiple clients. He needs a calendar system that can do the following: Can be updated from iCal (I'm pretty sure this just means CalDAV support) Needs to be able to show different clients the details of whats on his calendar for them, while showing other client's arranged times as only busy Wants to show it in a professional way, preferably on his own website. I was looking at Google Calendar, but alas it doesn't seem to actually support it like I thought it would. He was looking at MobileMe, but its simply public. Is there a calendar app or PHP application that can be installed on his server that can do this?

• Can't export Blender model for use in jMonkeyEngine SDK

  - by Nathan Sabruka

  I have a scene rendered in blender called "civ1.blend" which contains multiple materials (for example, I have one called "white"). I want to use this model in jMonkeyEngine, so I used the OGRE exporter to create .scene and .material files. This gives me, for example, a civ1.scene file and a white.material file.However, when I then try to import civ1.scene into the jMonkeyEngine SDK, I get an error along the lines of "Cannot find material file 'civ1.material'". Like I said, I have a white.material file, but I do not have a civ1.material file. Did anyone encounter this problem? How do I fix this?

• Choosing the right version control system for .NET projects [closed]

  - by madxpol

  I'm getting ready for my first "bigger" .NET project (ASP.NET MVC 3/4) on which I'm going to lead another 2 programmers and right now I'm choosing the right version control system for the job (plus I'm gonna use it for my future development too). My problem is that I did't use any version control system before, so I would like it to have as fast learning curve and intuitive merging as possible. So far I quickly looked at VisualSVN (I like the Visual Studio integration in it), but I'm reading everywhere how Git is awesome and dunno which one to choose (not limited to these two).. Maybe I'm ovethinking this but I like when everything goes smoothly:) I'd like to hear some opinions from people who used multiple version control systems (preferably on VS projects) what do you think is the less complicated and effective version control system for such a use (one to 5 man projects)?

• How much configurability to give to users regarding concurrency?

  - by rwong

  This question is a narrowing-down of these related questions: How much effort should we spend to programming for multiple cores? Concurrency: How do you approach the design and debug the implementation? Given that each user's computers may have different performance characteristics with respect to calculations, memory, disk I/O bandwidth and network I/O bandwidth, and that it is difficult to implement an automated self-tuning system in your software, how much configurability should we give to the end-users so that they can find ways (by trial-and-error?) to improve our software's efficiency? If we give users the ability to change these settings, how do we give visual feedback to users so they can measure the performance changes?

• How to reinstall bootloader after migration to SSD

  - by hijarian

  I must say, it was difficult to name this question. Basically, I need to properly reinstall the bootloader on my system, because I already have the working system disks for my OSes. The long story is this: I had the large slow HDD with Windows7 & Debian Wheezy dual-boot on it, perfectly bootable. Then, I ordered the SSD drive and prepared my system partitions to fit onto the much smaller SSD. I wanted the following schema: 128 GB Windows 24 GB / on Debian 86 GB /home on Debian Strange size for /home because there's no such thing as true 256GB disk drive. So, I've prepared such a partitions on my initial HDD and installed the new SSD and then I loaded the GParted live USB (can't remember now how it was really named), and then just copypasted the partitions from HDD to SSD. So, now I have the following partitions across the physical disks: SSD 128 GB copy of original Windows partition 24 GB copy of presumably Debian / 86 GB copy of presumably Debian /home HDD 128 GB Windows 24 GB / on Debian 86 GB /home on Debian ... several other partitions with non-system data ... And the behavior of the system right after the Ctrl+C, Ctrl+V in GParted was as follows: no GRUB, system boots right into the Windows on HDD. In BIOS settings are to boot from SSD first. I managed to create the Debian Testing installation USB and loaded it into the rescue mode, found that it identified my SSD as /dev/sda and installed the GRUB to the /dev/sda. Now my system loads the GRUB which lists both Windows and Debian. From HDD. So, I am now back into initial position. Please, how I should set up the GRUB so it'll load the OSes correctly from SSD? Should I fire up my Debian, fiddle with the GRUB's config and reinstall it again to the same place (at SSD)?

• Stacked Launcher Item Double Click Behaviour on Alt-tab

  - by Brandon Bertelsen

  Let's say that you have multiple firefox windows open. What you see happen is an additional arrow points to it's icon in the launcher. However, if you double click the icon, it displays all of the windows in a spread out fashion, similar to the behaviour from pushing Super + W, but only for that program group. Is it possible to make this window spreading behaviour occur with alt-tab? PS: No idea what tags I should use, or if the language (jargon) in the title or question is appropriate.

• What parameters to use to compare GUI frameworks / toolkits?

  - by gooli

  I'm doing some research on the best GUI toolkit to use for future products at the company. We're talking about a fairly large organizations with quite a bit of code and a complete rewrite project in planning. Don't ask. Anyway, I'm trying to create a list relevant parameters to judge the toolkits. What would you use to drive the comparison? Here's what I've got so far: Maturity Ease of development Ease of prototyping Ease of maintenance Size of hiring pool Available knowledge at the company Training costs Community size Community level of expertise (how hard to find good answers to complex problems) Amount of expert-level books available Ability to interface to other technologies Deployment considerations Visual aesthetics Ability to access OS resources Multiple monitor support (something that might come in handy in our particular application)

• The perfect RDP experience from Mac to Windows

  - by Sahil Malik

  SharePoint, WCF and Azure Trainings: more information For the reasons I mentioned in my keyboard remapping blog post, I live in a Mac+PC world. This means, I find myself frequently RDP’ing to Windows Machines from my Mac. And yes, that Metro UI on RDP is even more frustrating than it is without RDP. Mac is a different OS than Windows (duh!), and the way it handles multiple screens and spaces is entirely different from windows. This means, RDP experiences are tough to make 100% seamless. You can see the frustrations in the various reviews on the Microsoft RDP app on the Mac app store. It can be difficult to find the perfect settings for the perfect user experience. Well, here they are - Read full article ....

• My Sites Were Hacked. What To Do?

  - by Vad

  I host multiple domains with this very popular hosting provider and I just went into one of my sites and... I see a black page with message "Hacked by...". I checked and all my sites with the provider are showing this same page. Inside of file system I have seen the hacker placed all default.* and index.* files with this message. So the hacker overwrote all index pages, placed new pages and that is under every, I say again, every folder. Cleaning this up will be close to a most horrible job. What to do (right now I am awaiting the restore of files from hosting provider)? How to prevent this? Whom to blame?

• Choppy window movement in Gnome 3.4 on Ubuntu 12.04

  - by mjrussell

  I have been using Gnome 3.2 since Ubuntu 11.10 was released and it has always been perfectly smooth and performed extremely well, much better than Unity. After doing a clean installation of Ubuntu 12.04, Gnome 3.4 performs less well. If just one window of a relatively simple application, such as Gnome Terminal, is opened and moved around, the movement is sometimes very choppy, but the rest of the time it's perfectly smooth. The times when it's choppy seem to be when part of the window goes off the bottom or right side of the screen. Also, if there are multiple windows open, it is almost always choppy. These facts suggest to me that it's something to do with the compositor. Unity works perfectly smoothly. Memory usage is only at about 500-600MB, out of 3GB, even with a few things open. The graphics card is the on-board Intel graphics on the Core i5 M450. Does anyone have any ideas what might be causing this problem? Thanks

• Is having 'Util' classes a cause for concern? [closed]

  - by Matt Fenwick

  I sometimes create 'Util' classes which primarily serve to hold methods and values that don't really seem to belong elsewhere. But every time I create one of these classes, I think "uh-oh, I'm gonna regret this later ...", because I read somewhere that it's bad. But on the other hand, there seem to be two compelling (at least for me) cases for them: implementation secrets that are used in multiple classes within a package providing useful functionality to augment a class, without cluttering its interface Am I on the way to destruction? What you say !! Should I refactor?

• How do I push my initial snapshot to a subscriber server in SQL Server 2000?

  - by Kev

  I'm configuring Transactional Replication using the Push model. The scenario is: The SQL Servers: SQL01 (publisher) and SQL02 (subscriber) - both running SQL 2000 SP4. Both servers are standalone (i.e. not domain members) Both servers have their FQDN and NETBIOS names in their HOSTS files I've managed to configure SQL01 to publish my database and configured a Push subscription for SQL02 using the Push New Subscription wizard and set the Distribution Agent to update the subscription continuously. On the Push Subscription wizard "Initialise Subscription" page I've selected "Yes, initialise the schema and data" and ticked the "Start the Snapshot Agent to begin the initialisation process immediately" option. All the required services are running (SQL Agent). When I complete the wizard and browse the Replication - Publications folder I can see my publication (blue book with arrow). The publication shows the Push subscription and its status is Pending. If I look in the c:\Program Files\Microsoft SQL Server\Mssql\Repldata folder I see a number of T-SQL scripts for each table e.g. Products.bcp, Products.sch, Products.idx. What should happen now? Should my replicated database now (magically) appear on the subscription server?

• Do you want to be an officially certified Oracle ADF Developer?

  - by Grant Ronald

  We have just released an official certification exam for Oracle ADF Development.  This exam is aimed that those who are already getting hands-on with ADF and would like an official certification of their development skills. I was involved in writing some of the exam questions and this was an interesting experience.  We were looking to test not only a knowledge of the framework, but also a practical application of that knowledge.  Trying to do that in a clear question which related to multiple choice questions was sometimes difficult but I think we’ve produced a testing exam which, if you pass, shows a strong practical knowledge of ADF. Enjoy!

• International multi-OS keyboard layout for both coding and surfing?

  - by Nikolai Prokoschenko

  So yes, the problem has been raised in parts multiple times already. Still I'm looking for a keyboard layout that has the following features: Easy on fingers (Dvorak-like layouts welcome) Easy for coding Includes German characters (typing ä with AltGr-p is not ok). Works well with web-browsing (Ctrl-t and Ctrl-w on one hand, left one very much preferred, since that's where my ex-CapsLock, now Ctrl lies) Works well with default Emacs bindings Works on both Windows and Linux (at least easily installable) I've looked at Dvorak and Neo, they both have a "shortcut problem", i.e. web-browsing and most frequent Emacs combinations use both parts of the keyboard. Using right Ctrl is usually not an option, since it'll give me RSI much faster than keeping QWERTY/Z. Funnily enough, mirroring the default Neo layout would probably be enough for me. So, any ideas?

• Would this be considered Single Tenant or Multi-Tenant?

  - by Amy Anuszewski

  I'm sorry for this dumb, basic vocabulary question, but I've managed to confuse myself. As a company, we lease a managed server from a provider. In that sense, our server is a single tenant server. On this server, we have multiple customer databases. Each customer has its own database. We have been asked by a customer if we are a single tenant or a multi-tenant solution. From our perspective, we are the sole tenant of the server. But, what is the correct answer to the customer?

• Handling buildings in isometric tile based games

  - by MustSeeMelons

  A simple question, to which i couldn't find a definitive answer - how to manage buildings on a tiled map? Should the building be sliced in to tiles or one big image? EDIT: The game is being built from scratch using C++/SDL 2.0, it will be a turn based strategy, something like Fallout 1 & 2 without the hex grid, a simple square grid, where the Y axis is squished by 50%. Buildings can span multiple tiles, the characters move tile by tile. For now, the terrain is completely flat. Some basic functionality is in place, so I'm aiming to advancing the terrain and levels them selves - adding buildings, gates, cliffs, not sure about the elevation.

• What are good JS libraries for game dev? (HTML5)

  - by acidzombie24

  If i decide to write a simple game both text and graphical (2d) what libs may i use? Assuming we are using a HTML5 compatible browser. The main things i can think of Rendering text on screen Animating sprites (using images/css) Input (capturing the arrow keys and getting relative mouse positions) Perhaps some preloading resource or dynamically loading resources and choosing order Sound (but i am unsure how important this will be to me at first). Perhaps with mixing and chaining sounds or looping forever until stop. Networking (low priority) to connect a user to another or to continuously GET data without multiple request (i know this exist but i dont know how easy it is to setup or use. But this isnt important to me. Its for the question).

• Design: How to model / where to store relational data between classes

  - by Walker

  I'm trying to figure out the best design here, and I can see multiple approaches, but none that seems "right." There are three relevant classes here: Base, TradingPost, and Resource. Each Base has a TradingPost which can offer various Resources depending on the Base's tech level. Where is the right place to store the minimum tech level a base must possess to offer any given resource? A database seems like overkill. Putting it in each subclass of Resource seems wrong--that's not an intrinsic property of the Resource. Do I have a mediating class, and if so, how does it work? It's important that I not be duplicating code; that I have one place where I set the required tech level for a given item. Essentially, where does this data belong? P.S. Feel free to change the title; I struggled to come up with one that fits.

• Migrate from Thunderbird to Mutt

  - by deshmukh

  I am contemplating moving from Thunderbird to Mutt (provided it is feasible) to move to a faster, simpler application. My current Thunderbird set-up consists of multiple IMAP accounts (gmail and google apps). Only selected folders (read labels) in each IMAP account are stored locally. For all other folders, I glance through the headers and open a message only if I find it interesting. I also use folder bookmarks to navigate to folders quickly. I also move messages across folders with keyboard shortcuts. Is it possible to replicate the set-up in Mutt? Can someone share/ point to a sample muttrc file that does the same thing? It would be great if the muttrc file is adequately commented. On a side note, will it also be possible to import my messages from Thunderbird locally? That will save me considerable network traffic (about 2GB data stored locally).

• Keypress Left is called twice in Update when key is pressed only once

  - by Simran kaur

  I have a piece of code that is changing the position of player when left key is pressed. It is inside of Update() function. I know, Update is called multiple times, but since I have an ifstatement to check if left arrow is pressed, it should update only once. I have tested using print statement that once pressed, it gets called twice. Problem: Position updated twice when key is pressed only once. Below given is the structure of my code: void Update() { if (Input.GetKeyDown (KeyCode.LeftArrow)) { print ("PRESSEEEEEEEEEEEEEEEEEEDDDDDDDDDDDDDD"); } } I looked up on web and what was suggested id this: if (Event.current.type == EventType.KeyDown && Event.current.keyCode == KeyCode.LeftArrow) { print("pressed"); } But, It gives me an error that says: Object reference not set to instance of an object How can I fix this?
