• Text box select issue

  - by Kent Boogaart

  I have this issue where the entire text in text boxes is selected whilst I'm typing in it. For example, in FireFox search box I'd try to type "foo" but end up with "o" because I managed to type "fo" before everything was selected, and then typed "o" which replaced the "fo". When it happens, it is incessant - not just a one-off. But it doesn't happen all the time, and I haven't managed to figure out what causes it to start and stop. Is this a known problem with an easy solution? EDIT: this has nothing to do with touchpad. I get this occasionally even on a machine without one. I can usually rectify the issue just be alt-tabbing about a few times.

• Seo Google Publisher Network

  - by Andy

  I'm just about to start a new business which creates niche affiliate sites. I'm curious about the impacts to me from Google of all the urls being hosted with the same analytic tags, webmaster tool tags and server ip ranges. To benefit the most from google's serps should i have each domain within seperate analytic accounts and webmaster tools or is it ok for me to have all of my domains within one account. My issue is duplicate content and the fact that i am building a publisher network and i'm not sure how much google likes them. I'm notoriously bad at searching and as such havent found what i'm looking for yet. Any help would be very much appreciated.

• Oracle Service Contracts – Calculate Estimated Tax with Higher Accuracy

  - by LuciaC-Oracle

  On a Service Contract the tax rate and its effectivity can change over the contract duration.  Hence, service organizations need to provide an accurate picture of the estimated tax that the customer might end up paying.  Prior to Release 12.1.3+, the Oracle Service Contracts application calculated the estimated tax based on the line/ sub line start date.  With Release 12.1.3+ (via Patch 16601269:R12.OKS.B) , new functionality provides users with an option to calculate tax at contract billing schedule level, thereby considering the changes in tax rate effectivity at that level.A new profile option 'OKS: Calculate Tax at Schedule' has been introduced which can be used to control whether the existing or new functionality is used.  If the profile is set to 'Yes' the application calculates tax at the billing schedule level for all lines/ sub lines.  For more details on the implementation steps and functionality, please refer to Doc ID 1676700.1: Oracle Service Contracts – How To Calculate Estimated Tax with Higher Accuracy.

• Processing a list of atomic operations, allowing for interruptions

  - by JDB

  I'm looking for a design pattern that addresses the following situation: There exists a list of tasks that must be processed. Tasks may be added at any time. Each task is wholly independent from all other tasks. The order in which tasks are processed has no effect on the overall system or on the tasks themselves. Every task must be processed once and only once. The "main" process which launches the task processors may start and stop without warning. When stopped, the "main" process loses all in-memory data. Obviously this is going to involve some state, but are there any design patterns which discuss where and how to maintain that state? Are there any relevant anti-patterns? Named patterns are especially helpful so that we can discuss this topic with other organizations without having to describe the entire problem domain.

• How are Programming Languages Designed?

  - by RectangleTangle

  After doing a bit of programming, I've become quite curious on language design itself. I'm still a novice (I've been doing it for about a year), so the majority of my code pertains to only two fields (GUI design in Python and basic algorithms in C/C++). I have become intrigued with how the actual languages themselves are written. I mean this in both senses. Such as how it was literally written (ie, what language the language was written in). As well as various features like white spacing (Python) or object orientation (C++ and Python). Where would one start learning how to write a language? What are some of the fundamentals of language design, things that would make it a "complete" language?

• Programming for Digital frames

  - by spartan2417

  A project has recently come to my attention but i have no idea where to start or even if its possible. The idea revolves around programming a clock that is displayed inside a digital photo frame. The user would then be able to put different pictures corresponding to different times inside a usb pen for example, which would load as soon as you put the usb in. The project itself would be a really neat project - if it was just on a computer. I have no idea if what im talking about it even possible on a digital photo frame and if it is what language? Anyone who has any input at all would be great. My current idea is to maybe have a small device at the back, SSD, that runs the program through a screen, completely by passing standard digital photo frames, again though i dont know how to begin with this. And yes ive tried google (although it helps to know what to google).

• USB Storage Device Automount

  - by matto1990

  Under Ubuntu 10.04 one of the problems which appeared is that USB devices would no longer automatically mount when plugged in. Normally I would get a pop up message asking what application I wanted to open the newly plugged in device with, however now that doesn't happen. This happens regardless of the way the device is formatted (NTFS or FAT32) and all other USB devices (printer, keyboard and mouse) work perfectly. My current solution is the mount them manually using sudo mount dev/... /medai/... however to be honest I'm just getting tired of having to do this. I'm happy to post any extra information you are likely to need. I know there will be lots of places I could look to find out what's going wrong but I have no idea where to start really.

• How can I become a technical trainer from a software developer?

  - by Abhilasha

  I am a software developer; in fact a mobile application developer with 4 years of experience. I am passionate about training. I have never been an official trainer but, I have trained freshers on mobile technologies. Now how do I become a professional technical trainer. I have following questions: Do I need some kind of professional certification or degree? Is it too early for me to start as a trainer? I mean experience wise. I will not ask if it's worth it because I am very keen on pursuing training as a profession. However, if I have to be up to date with technology, I don't think I can give up coding and pursue training full time. Any pointers or guidelines would be helpful.

• PyQt design issues

  - by Falmarri

  I've been working on a my first real project using PyQt lately. I've done just a little bit of work in Qt for C++ but nothing more than just messing around. I've found that the Qt python bindings are essentially just a straight port of C++ classes into python, which makes sense. The issue is that this creates a lot of messy, unpythonic code. For example if you look at QAbstractItemModel, there's a lot of hoops you have to go through that forces you to hide the actual python. I was just wondering if there's any intention of writing a python implementation of Qt that isn't necessarily just a wrapper? Either by Nokia or anyone else? I really like Qt but I would love to be able to write more pythonic code. I hope this is OK to ask here. I'm not trying to start a GUI war or anything.

• GRUB not showing /dev/sda2 is Windows 7 Loader

  - by Ricardo

  A few days ago I accidentally deleted Ubuntu partition using GParted. I thought Windows 7 would start normally, but I got a "grub-rescue" screen instead. Then, I recreated a partition for Ubuntu (/dev/sda6) and reinstalled it. Ubuntu starts properly now; but GRUB shows me /dev/sda2 is Windows Recovery System (WRS), what is false, since /dev/sda1 is WRS and /dev/sda2 is Windows 7 Loader. I booted using Windows 7 disk and tried to correct this problem automatically and by bootrec.exe /fixboot and /fixmbr, and nothing is able to fix my problem. Yet, Windows (disk) says there is no OS in my computer. What should I do? Will I have to erase my hard disk to get Windows 7 back?

• Painfully Slow iPhone Backup?

  - by Christopher House

  And now for something completely different... For the past couple of weeks, I've not been able to sync my iPhone.  What happens is that I plug it in to my computer, start the sync and two hours later, iTunes shows it's about 75% complete.  After some googling, I tried a few things like deleting old backups, changing some settings, etc, but nothing seemed to help.  Tonight I decided I'd try deleting all the photos and videos on my phone.  Sure enough, that did the trick.  I'm now able to successfully sync in a reasonable amount of time.

• Design for future changes or solve the problem at hand

  - by Naveen

  While writing the code or during design do you try to generalize the problem at the first instance itself or try to solve that very specific problem. I am asking this because, trying to generalize the problem tends to complicate the things (which may not be necessary) and on the otherhand it will be very difficult to extend the specific solution if there is a change in the requirement. I guess the solution is to find the middle path which is easier said than done. How do you tackle this type of problem ? If you start generalizing it at what point of time you know that this much of generalization is sufficient ?

• What is the name of this array transformation?

  - by Brandon Tilley

  Start with an array of arrays; in this case, they are different lengths in order to demonstrate the technique, but they do not have to be. [[1,2,3,4], [5,6,7], [8,9,10], [11,12,13,14,15]] At the other end of the transformation, you have an array of arrays where the first array contains the first element from each of the original arrays, the second array contains the second element from each of the original arrays, and so on. [[1,5,8,11], [2,6,9,12], [3,7,10,13], [4,14], [15]] Is there a mathematical or CS term for this operation?

• What method do I use to manage an app-specific background process?

  - by Simon Dubois

  I am developing an application with different behavior depending on the arguments : "-config" starts a Gtk window to change options, start and close the daemon. "-daemon" starts a background process that does something every X minutes. I already know how to use fork/system/exec etc... But I would like to know the main logic of such application to : restart or refresh the daemon when configuration change. keep only one instance of the daemon. I have read that killing the daemon to restart it is not a clean way to do. How other applications do ? (ubuntuone, weather forecast, rss feed working with notification area) Thanks for your help. PS : I don't want to create a system-wide daemon, just a user application with a background process.

• How to run ubuntu-tweak's janitor automatically?

  - by Eliran Malka

  My aim is to have the janitor running at startup, with a pre-configured profile (e.g. clear redundant packages and browser cache). The website is lacking any documentation or usage instructions, and I could not find any information on this here as well. I tried, naturally, to start ubuntu-tweak from the command line, hoping additional API exists that will come through in this (allegedly) simple task. I only got as far as: ubuntu-tweak -f janitor which is a step in the right direction, but what's still missing is a command for the clear action. Is such a command available, or is there any better way of achieving the desired behavior?

• Navigate Quickly with JustCode and Ctrl+Click

  Ctrl + Click is a widely used shortcut for Go To Definition in many development environments but not in Visual Studio. We, the JustCode team, find it really useful so we added it to Visual Studio. But we didn't stop there - we improved it even further. Read on to find the details. With JustCode you get an enhanced Go To Definition. By default you can execute it in the Visual Studio editor using one of the following shortcuts: Middle Click, Ctrl+Left Click, F12, Ctrl+Enter, Ctrl+B. The first usage of this feature is not much different from the default Visual Studio Go To Definition command use it where a member, type, method, property, etc is used to navigate to the definition of that item. For example, if you have this method:         public void Start()         {             lion = new Lion();             lion.Roar();         } If you hold Ctrl and click on the usage of the lion you will go to the lion member definition. If you hold Ctrl and click on the Lion you will go to the Lion class definition. What we added is the ability to easily find all the usages of the item you just navigated to. For example:     public class Lion     {         public void Roar()         {             Console.WriteLine("Rhaaaar");         }     }   If you hold Ctrl and click on the Lion definition you will see all the usages of the Lion type; if you click on the Roar method definition you will see all the usages of the Roar method: And if there is only one usage you will get automatically to that usage. In the examples I use C#, but it works also in VB.NET, JavaScript, ASP.NET and XAML. Why we like this feature? Let me first start with how the Ctrl+Click (or Go To Definition command) is used. We noticed that developers use it especially in what we call "code browsing sessions". In simple words this is when you browse around the code looking for a bug, just reading the code or searching for something. Sounds familiar? In our experience when you go to the definition of some item you often want to know more about it and the first thing you need is to find its usages. With JustCode this is just one click away. Why Ctrl+Click/Middle Click over F12/Ctrl+Enter/Ctrl+B? Actually you can use all of them. But during these "code browsing sessions" we noticed that most developers use the mouse. So the mouse is already in use and pressing Ctrl+Click (or the Middle Click) is so natural. During heavy coding sessions or if you are a keyboard type developer F12 (or any of the other keyboard shortcuts) is the key. We really use heavily this feature not only in our team but in the whole company. It saves us a bit of time many times a day. And it adds up. We hope you will like it too. Your feedback is more than welcome for us. P.S. If you dont want JustCode to capture the Ctrl+Click and the Middle Click in the editor, you can change that in JustCode->Options->General in the Navigation group. Keyboard shortcuts can be reassigned using the Visual Studio keyboard shortcuts editor.Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

• Simple script - execute command on selected file

  - by askmoo

  I want to make a script that will execute .jar file on selected file. Later I will add that script to right-click menu via the tool Nautilus Actions or just place it into nautilus-scripts folder. I have a problem creating script. When I am in a usual console screen and want to execute this jar file on any other file, I use this syntax myfile.jar ./someotherfile.xml and the jar file will write the output to the console screen. So I created a file script.sh, added lines in it #!/bin/bash /home/username/myfile.jar $1 But it does not output anything. I know I am doing something wrong. Please help. To sum, I need a script that will use selected file as a parameter, open the gnome-terminal, inside that terminal it will start JAR file and pass it the selected file. I am confident that this is a very simple procedure, but I am total newbie with shell scripting.
