  • Reusing elements in StandardStyles.xaml

    - by nmarun
    In one of my previous blogs (second point) , I mentioned not to modify the StandardStyles.xaml, but instead to create your own resource dictionary. I also mentioned how to declare your custom styles dictionary in the App.xaml file. If you want to reference or build upon from an existing style in the StandardStyles.xaml file, do the following: 1. Remove the entry for StandardStyles.xaml in the App.xaml file 2. Add your custom resource dictionary in the App.xaml file 1: <!-- App.xaml --> 2: <...(read more)

  • Given two sets of DNA, what does it take to computationally "grow" that person from a fertilised egg and see what they become? [closed]

    - by Nicholas Hill
    My question is essentially entirely in the title, but let me add some points to prevent some "why on earth would you want to do that" sort of answers: This is more of a mind experiment than an attempt to implement real software. For fun. Don't worry about computational speed or the number of available memory bytes. Computers get faster and better all of the time. Imagine we have two data files: Mother.dna and Father.dna. What else would be required? (Bonus point for someone who tells me approx how many GB each file will be, and if the size of the files are exactly the same number of bytes for everyone alive on Earth!) There would ideally need to be a way to see what the egg becomes as it becomes a human adult. If you fancy, feel free to outline the design. I am initially thinking that there'd need to be some sort of volumetric voxel-based 3D environment for simulation purposes.

  • How can I programmatically block user input for a given time?

    - by black_puppydog
    As a person working in computer science working offline to avoid facebook and thelike is not always (meaning hardly ever) possible for me since I mostly have to be online to work. I have tried leechblock and similar things but the problem becomes that at some point I start making systems for myself to hack, which is kind of pointless if oyu have root. I would very much like to try out the method described here. (Short version: reboot your PC every time finish a task or get bored with it) Unlike for the author of this blog my work is mainly done not in screen sessions but in IDEs ans other not-so-fast-to-start-up stuff, meaning a full reboot including loading all my programs will take its time. So, the question is: How can I block all user input and preferrably blank the screen for a given amount of time? The idea would then be to have a keyboard shortcut to activate the script/program (which would probably also have to have root i guess?)

  • Calculate initial velocity of a 3d vector-based projectile

    - by Frotty
    Okay, so I got a Projectile with 2 Vectors, position and velocity. I now want to calculate the initial velocity for it in order to reach a specific point on the map. Or actually, how high has the start z-velocity to be (because x and y are probably defined by a speed variable) in order for the projectile to hit the marked position. The projectile is influenced by a constant gravity vector. All calculations are done 32 times per second. I want this, because I don't want to use a parabola function, so the projectile can still be influenced by other sources, simply adding some velocity. I didn't really find anything referring to that topic and would be glad for every helping answer, Thanks.

  • Are there any surveys on to what degree developers like or hate scrum ?

    - by dparnas
    Background: During a conference an analyst pointed out in a tweet that developers hate scrum. Myself and another person responded that this was not the case, and started discussing different scenarios on why developers would dislike scrum. One of the scenarios where that lazy developers are not able to hide in a scrum project. They are constantly challenged by the team to contribute. This discussion resulted in a blog post and video http://elsewhat.com/2010/05/20/lazy-developers-hate-agile-and%C2%A0scrum/ I've gotten three comments which I've tried to answer in a neutral way, but they comments do point out that there are some people who loathe scrum (and I am always 100% certain they are not lazy developers). Question Have there ever been a survey among developers on to what degree developers like or hate scrum ?

  • Why does Linq to Entity Sum return null when the list is empty?

    - by Hannele
    There are quite a few questions on Stack Overflow about the Linq to Entity / Linq to SQL Sum extension method, about how it returns null when the result set is empty: 1, 2, 3, 4, 5, 6, 7, and many more, as well as a blog post discussing the issue here. Now, I could go a flag these as duplicates, but I feel it is still an inconsistency in the Linq implementation. I am assuming at this point that it is not a bug, but is more or less working as designed. I understand that there are workarounds (for example, casting the field to a nullable type, so you can coalesce with ??), and I also understand that for the underlying SQL, a NULL result is expected for an empty list. But because the result of the Sum extension for nullable types is also not nullable, why would the Linq to SQL / Linq to Entity Sum have been designed to behave this way?

  • How to structure my java packages

    - by MightyPork
    I have a Java library, quite a huge one. I'm asking regarding Best Practices of structuring the source. For example, the logging sybsystem: Option 1: All in one package, named to sort nicely Log - static accessor LogMonitor - interface for log minotor LogMonitorBase - abstract class LogMonitorStdout - print log to console LogWriter - interface for file logger LogWriterSimple - log writer with just one log file LogWriterArchiving - log writer that handles old log files Option 2: Subpackages for Monitors and Writers, with better names Log monitors/LogMonitor monitors/BaseMonitor monitors/StdoutMonitor writers/LogWriter writers/SimpleLog writers/ArchivingLog The second maybe looks better, but perhaps it's not so practical from the java point of view (two extra packages). What do you suggest as the best practice here? A lot in one package, grouped by naming prefixes, or a lot of subpackages with better names?

  • Setting Up Audio on a Server Install

    - by tdcrenshaw
    I'm running on a clean install of 10.10 Server edition and have alsa-base, alsa-tools, alsa-utils, alsaplayer, and alsa-firmware-loader installed. At one point I installed pulseaudio, but I have since removed it. I've tried the following lspci | grep audio 00:1f.5 Multimedia audio controller: Intel Corporation 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) AC'97 Audio Controller (rev 01) 01:06.0 Multimedia audio controller: Creative Labs [SB Live!

  • Windows Communication Foundation 4 - ISBN - Initial Comments

    - by TATWORTH
    Windows Communication Foundation 4 - ISBN 978-0-7356-4556-1 is one of the Microsoft Step-By-Step books. I will be studying this book over the comming weeks. What I have seen so far impresses me. One very practical item that more books of the type should have was the "Finding your best starting point". There is one feature about this book that I hope Microsoft Press will provide on more books and that is to also provide the book electronically via Safari. Included in this is getting the book as a PDF!

  • Restricted pathfinding Area

    - by SubZeron
    So i'm triying to create a little "XCOM : Enemy Unknown" like game ,and using the Aron Granberg's Pathfinding-Tool (free version) to handle the "click to move part. i want to add a little trap system where the hero get stuck inside an area, so he will have only the possibility to move inside this trapped area, so far everything is fine however when i click outside the trapped area, the hero try to reach the destination even though the wall will prevents him from reaching it. so my question is, is there any way to restrict the area where the pathfinding system work to the trapped area dynamically. and wich Graph Type is recommended to use in this situation or this kind of Games (Grid Graph/Navmesh Graph/Point Graph). Thank you. image link for explanation : https://dl.dropbox.com/u/77993668/exemple.jpg

  • How do I get a Line6 UX1 soundcard to work?

    - by the_drow
    I own a Line6 UX1 soundcard and I would like to make it work for Ubuntu. I have followed the instructions here and it worked. But at some point I upgraded my kernel version (not sure what uname -a prints but it's related) and it stopped working. Here's what uname -a prints: Linux ubuntu 2.6.32-29-generic #58-Ubuntu SMP Fri Feb 11 20:52:10 UTC 2011 x86_64 GNU/Linux I figured out that maybe it's installed per version so I used svn update and hit make again. My guess was right as it copied the relevant files to the new version's folder. I restarted and still nothing. Should I revert to an older version? Or is there a solution here?

  • Expression Engine vs Drupal for Theming

    - by user793011
    Ive been using Drupal for years and now with work need to learn Expression Engine. Im interested in the comparison of Drupal and Expression Engine, but purely from a theming point of view (Ive no doubt Drupal is more powerful for development). Does anyone have any insights? It seems EE does give you more control over the exact html outputted, but is this necessary? I design my graphics first and Ive always been able to make exactly what I wanted in Drupal (some theme overrides could be easier, but ive got there in the end). Thanks

  • Google search results page titles "hijacked" by porn

    - by rfoote
    Sorry, that title probably doesn't make much sense. Over the past couple of weeks, we've noticed that the search results from Google for some of our drupal-powered sites are having their page titles hijacked somehow. An example would be: free streaming porn - [Actual page title] There are other variations of the porn prefix, that's one of the more tame ones. I looked in the databases for each of these sites and the titles haven't actually been changed or anything along those lines. When you click on the result to visit the page everything looks normal (sans porn stuff). Would anyone be able to point me in the right direction as to what the cause of this is? Searching Google for the potential problem isn't being much help, yet. Thanks in advance!

  • Distorted text in programs

    - by Teneff
    I've installed Ubuntu 11 with gnome and in some point the text in the programs becomes unreadable like this. It's not only the text, but even the desktop background looks awful.

  • Different set of workspaces for each monitor? Ubuntu 13.04 with Unity

    - by Darren
    currently for my new setup, I have a 3 monitor setup. With an NVIDIA Geforce GTX 770(if this matters for this). What I'm wanting to do, is to create a separate set of workspaces for each monitor. For instance: Monitor 1 has a set of 4 workspaces, that are specific to monitor 1, and change independently of the other monitors. Then the other 2 monitors also have their own set of 4 workspaces. So in total I would have 12 workspaces, but each monitor would have it's own set of 4 that work independently from the others. I've read things about Xmonad and Xinerama, but I'm not really sure where to go from here. I haven't ventured to far into different window managers and everything. I'm sure there's not a tool that does this, but if someone could point me in the right direction(I've been using Ubuntu for about 4 years so I can figure some things out on my own too).

  • What's the reason exceptions are heavily used in managed (C# and Java) languages but not in C++? [on hold]

    - by ZijingWu
    AFAIK, a lot of C++ projects don't allow exceptions and deny them in coding guidelines. I have a lot of reasons, for example, exception is hard to handle correctly if your binary needs to be compiled by separate and different compilers. But it doesn't fully convince me, there is a lot of projects which are just using one compiler. Compared to C++, exceptions are heavily used in C# and Java and the reason can only be that exception are not bringing enough benefit. One point is debugbility in practice. Exception can not get the call stack in C++ code, but in C# and Java you can get the call stack from exception, it is significant and makes debugging easier. No-callstack is not the fault of the exception, it is the language difference, but it impacts the exception usage. So what's the reason that exceptions are frowned upon in c++ programs?

  • Credit Card Payment Processing which APIs do you use?

    - by user3330840
    It's for a Point of Sale Terminal where the customer will bring the physical credit card and it will be swiped through the terminal. The business has a merchant account on some banks. So, how do I start accepting credit cards in my app? The credit cards that needs to be accepted include: visa, master-card, amex, discover. Which APIs do I need to use? The programming language doesn't matter it can be in any programming languages Java/C#/C++/Python or anything. Will there be a single API or multiple APIs that need to be integrated? (I know some about PCI compliance and security encryption)

  • Windows 7 and 11.10 side by side from scratch what am I doing wrong?

    - by Bill.Caffery
    I have tried everything I can think of at this point and I'm at a total loss. I have a 2TB drive I want to install Windows 7 and 11.10 (both are 64 bit) side by side, but once I install Windows it must need gpt to work or something because no matter how many times I've removed it, it always returns. If I use gdisk and set the disk as mbr, Windows won't load. Now this last time I ran gdisk and tried to boot into Windows before I installed Ubuntu all the way and ended up at a grub rescue prompt. Any help please? Also let me say I have been searching and reading for days and have tried everything I can find to make this work so this isn't a one time event, it's continual.

  • Does Ubuntu 12.04 supports for B75 boards?

    - by rail02000
    I want to build a new computer with Intel G840 CPU and Gigabyte B75M-D3H motherboard and install Ubuntu (or Kubuntu) 12.04 64bit on it. However, I'm worried about whether the chip is too new and whether that Linux Kernel now has support for it. According to the article [Phoronix] Intel Core i7 3770K Ivy Bridge Linux Performance Review ,the Linux kernel is ready to work on the chip. Existing Intel Sandy Bridge motherboards/chipsets are compatible with Ivy Bridge processors, but earlier this month Intel launched the new Panther Point chipsets that are already compatible with Linux too: the B75, H77, Z75, Z77, HM75, HM76, UM77, and HM77. But I didn't find further information or cases about running Ubuntu on the chip. So,is it OK to run Ubuntu on the board? Do I need to upgrade the kernel to a newer version (3.4 or 3.5 etc.) to get the system more smoothly? Or should I choose boards with H61 chip? Thank for your response!

  • One man software developer product success stories? [on hold]

    - by EugeneKr
    I've got a bad feeling that this question is not appropriate here.. Hopefully you can point me to the right place to ask such a thing (not google though, been there). I want to create my own product, but for some reason have no ideas, so decided to see what people have already done. I would like to start by myself too. I don't mind expanding, but at later stages when it is absolutely necessary. Anyway, to give you an example. There is a guy who created bingo card generation software, then somebody made a wedding planner software and they seem to be doing pretty fine. I would like to know more such cases to draw inspiration from. Do you know such people or maybe you are one of them? Also, if there are places on the net where they dwell, don't hesitate to tell me :) Thanks!

  • Does tweeting 9 to 5 hurt job applicants?

    - by evadeflow
    If you were looking into a job applicant's background and discovered that he or she has 1200 followers on Twitter and averages 50 tweets per day (more than half of which are during business hours), would it affect your hiring decision? How and why? Personally, I'd be a little worried about the candidate's ability to focus on the job at hand if they're constantly checking in with their 'tweeps' thoughout the day. In non-tech jobs, a lot of companies simply block Twitter as an irrelevant distraction. But it can be a useful resource---to programmers in particular. I just wonder how much is too much. At what point does it become a red flag?
