  • Simplicity-effecincy tradeoff

    - by sarepta
    The CTO called to inform me of a new project and in the process told me that my code is weird. He explained that my colleagues find it difficult to understand due to the overly complex, often new concepts and technologies used, which they are not familiar with. He asked me to maintain a simple code base and to think of the others that will inherit my changes. I've put considerable time into mastering LINQ and thread-safe coding. However, others don't seem to care nor are impressed by anything other than their paycheck. Do I have to keep it simple (stupid), just because others are not familiar with best practices and efficient coding? Or should I continue to do what I find best and write code my way?

  • DHCP won't start / subnetting

    - by user114371
    I recently changed the IP address on an Ubuntu 12.04 server I have in my lab, which is running isc-dhcp-server. After doing so and modifying the dhcpd.conf file, my dhcp service would not start. I basically used the same configuration, except I modified everything to use /25 scopes rather than /24. When I try to start / restart the service, I see the following: MY@ubuntuserver:~$ sudo service isc-dhcp-server restart stop: Unknown instance: isc-dhcp-server start/running, process 20918 It looks like it starts, but it isn't actually running and Webmin states that the DHCP service is not running. So my question is, does isc-dhcp-server support subnetting (CIDR) style scopes, or must they be class A / B / C scopes (doesn't seem likely)? I've double checked the interface reference (this is a VM with only one defined eth0 interface) and everything else I can thing of.

  • How to go about "taking over" an open-source project?

    - by LuxuryMode
    There's an open-source project that I'm interested in and use regularly. It's licensed under the Apache License 2.0 and it has basically no activity any more. It's hosted on Google Code and I'm interested in continuing it's development. I'm new to the open-source process and I'm trying to figure out the appropriate way to go about this. Can I just check it out and push it to github so I can continue it's development in the open there? Should I contact the project "owner" first? Also, do I leave all the author information at the top of the classes, etc even though I'm going to be making changes..(I'm assuming the answer is yes)? Also, how do I practically adhere to the license requirement of "all modifications are clearly marked as being the work of the modifier"? Do I place a comment by every change I make?

  • Upgrade two computers on the same WIFI network from 12.04 to 12.10

    - by deshmukh
    I have two computers on the same WIFI network at home. Both run on Ubuntu 12.04 and both will need to update to 12.10 shortly. There are some applications that are installed on one but not on the other and vice versa. But they share a large many applications. Please indicate how can I upgrade both in such a way that: I download all the packages required on Computer 1 Move the downloaded packages to the other computer using external HD (that is much quicker than over WIFI) Then upgrade Computer 1 Then upgrade Computer 2 -- after it downloads any packages that are not already available. Also, I am a newbie and would be grateful if the process is simple and properly explained.

  • Is it possible to outsource design properly?

    - by Eric
    I work in a company going through a downsizing process. It is assumed that a lot of "let go" developers jobs will eventually be outsourced. Some of those programmers had some design to do. Is it possible to outsource both design and creation/coding properly? I feel that by outsourcing design, we lose any in-house capability of really "owning" the code. It will be very difficult to maintain. Also we'll have a hard time ensuring a proper development. How can I address those issues?

  • Windows 8 and "Formerly known as Metro" apps, an experience with PDF app

    - by Kevin Shyr
    I'm slowing and surely getting used to Windows 8.  It is no doubt a slow process since I still run daily on an XP machine, a Vista machine, and 3 windows 7 box. A new quirk I found regarding Windows 8.  I never thought it was important to learn how to close a "formerly known as Metro" app (what do we call those these days?).  Then I attached a portable drive to my laptop and opened up a PDF file, and I couldn't safely remove the hard drive afterwards because I did not know how to close the PDF reader app. I have since learned that if you want to close an app, you can try Alt + F4 mouse over the top left corner and swipe down, right-click to close you app Windows Key + TAB, right-click to close the app All these make me wonder, how do you do this in a phone or tablet?

  • Steam not displaying text on wine 1.5 running on Ubuntu 12.04

    - by Jscags
    Hello fellow dwellers of askubuntu, as the title says I'm having difficulties with getting Steam to run properly. I think I have the solution but I am pretty incompetent with Ubuntu (just started using it the other day) so a step by step process would be unbelievably appreciated! Here are the links to what I think possible solutions are: [1] https://bbs.archlinux.org/viewtopic.php?id=146223 [2] http://bugs.winehq.org/show_bug.cgi?id=31374 I've tried googling how to preform the solutions such as changing the alias/script for steam (no idea what that is) to -no-dwrite or launching with wine Steam.exe -no-dwrite. The dwrite seems to be the issue in all this but I can't for the life of me figure out how to do anything about it. Any useful input is what I'm hoping for but for the brave soul who feels like typing a bit more, perhaps a step-by-step list of instructions starting from downloading Steam off the official website, would be my saving grace. If there is any more info you guys need let me know and I'll of course be happy to oblige!

  • How should I synchronize configurations and data across computers?

    - by lfaraone
    Imagine I have three Ubuntu computers home, laptop, beach-house. They all have the same version of Ubuntu, 10.04 installed, and are kept up to date from the repositories. I use f-spot, thunderbird, and google-chrome on all of the computers. Is there a way to keep the data and configuration in sync across them, without requiring constant connectivity for normal (non-synchronous) usage? For example, they should be usable without network connectivity, so something like NFS won't work. An ideal solution would not require manual action to start the syncing process.

  • Install Ubuntu 12.04 on Drive "D"?

    - by Bill Jones
    I have a Dell Inspiron 531S that originally came loaded with Windows Vista. A couple years ago I purchased a copy of Windows 7, formatted the hard drive and installed the updated operating system. In the process I formatted the 10 GB recovery drive partition on drive D as it was no longer needed for Windows Vista. I would really like to install Ubuntu 12.04 LTS alongside Windows 7 using the empty 10 GB drive D:. I have two questions. (1) Can Ubuntu be installed on a separate partition, a drive removed from the boot sector on drive C:? (2) If so would Grub be installed in the boot sector and properly select Windows 7 on drive C: or Ubuntu 12.04 on drive D?

  • Microsoft DevDays 2010 Day 2

    I delivered a session today that describes what's new in Office 2010 for solution developers. It's a session that I have evolved over the past year. My core demos have also evolved, and I'm pleased with the impact they make. The session was well attended, and I was pleased to see plenty of enthusiasm for Microsoft Office solutions from the good folks in the Netherlands. My demo image is still based on Office 2010 Beta 2, and that's something I'm already in the process of changing. I'm moving to RC...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.

  • Ubuntu 12.04 upgrade (from 11.10) removed all packages installed

    - by Jagmal
    I upgraded from Ubuntu 11.10 to 12.04 using bootable USB. After upgrade, all non-default packages from 11.10 are gone. For ex, I did not have Chromium, Eclipse etc. Although, I could see these in the History in the "Ubuntu Software Center". Is there any way I can retrieve all these packages (even reverting back to 11.10 is also fine with me)? What could be a possible reason for this (We plan to upgrade a few more machines)? During the upgrade process, I had unchecked the box which asked permission to look online for upgrade/packages. Co

  • Trouble with Ubuntu 12.10 install/evaluation

    - by Mike H
    I am trying to install Ubuntu 12.10 onto my Compaq Presario SR1215CL. I downloaded ubuntu-12.10-desktop-i386.iso file using BitTorrent and burned it to a blank DVD-RW. When I boot the computer with the Live Disk in the disk tray I am able to get to the Welcome screen. If I click on "Try Ubuntu" I am left at a blank screen except for the desktop background. There are no menus, toolbars, icons, etc. If I press Ctrl+Alt+Delete at this stage I am able to log out of the Live Session, but am unable to log back in. If I click on "Install Ubuntu" instead, I am able to proceed fairly far into the installation process, but eventually it quits and drops me to the same blank screen as above. I'm not sure at which stage the installer quits, but it does ask me to identify the issue and solve the problem myself from inside the Live Session, which doesn't work. Does anyone have some suggestions on how to get Ubuntu installed and working?

  • How to create Button/Switch-Like Tile where you can step on it and change its value?

    - by aldroid16
    If the player step on Button-Tile when its true, it become false. If the player step on Button-Tile when its false, it become true. The problem is, when the player stand on (intersect) the Button-Tile, it will keep updating the condition. So, from true, it become false. Because its false and player intersect on it, it become true again. True-false-true-false and so on. I use ElapsedGameTime to make the updating process slower, and player can have a chance to change the Button to true or false. However, its not a solution I was looking for. Is there any other way to make it keep in False/True condition while the Player standing on it (The Button tile) ?

  • Changing the priority of Gnome Shell

    - by user32655
    I want to give Gnome-Shell the highest priority, but I couldn't change the priority on the System Monitor, an error messeage says: Can't change priority's process with pid 2841 to -5. Access denied I tried the following commands: gksu gnome-system-monitor But I can't find Gnome-Shell on the processes list, so I tried "renice command", like this: sudo renice -15 2841 And finally got this problem, the Gnome-Shell's PID always changes, it's not the same PID numbers, so I have to change the priority every time I start up my system. Can anyone help me? Thanks.

  • How accurate is header information received?

    - by blankip
    Please see What could keep a javascript from loading properly on a page? In the header it shows that it is coming from IIS 6.0. How accurate is this information? Also this vendor (which is the worst I have worked with) made us go through a huge server switch process. Did they "upgrade" to W2003 IIS6.0? What would be the reason for a "new" server to be running this old of a version of IIS? Am I missing something?

  • How to start to gain experience of managing a project

    - by Tim
    There are some job requirements of project management experience for a programmer, such as: the candidate has to have some experience managing a project, not necessarily with subordinates, but rather having worked on a project all the way from design down to test. I was wondering what "subordinates" mean here? if there are some books, webpages or elsewhere with both general guideline and simple practical sample projects to help one get some basics about the whole process of a project. I am particularly interested in projects for both Linux and Windows, in C, C++, Python, Java. I am considering to start by playing on my own, not eager to find a company yet. My major was not CS, so I might lack the basics.

  • Need help with AMD catalyst control center

    - by user254074
    I just built my first HTPC and I hooked it up to my Sony KDS-R60XBR1 and I am having display issues. I believe this is only a 1080i display and when I select 1920x1080 on the resolution I get strange lines on the display when anything moves on screen. I am guessing this is because it is putting it in 1080p and the TV cannot process that. As of now I have lowered the resolution and that worked but I would like to get this set at 1080. Also I cannot change the underscan. I am stuck with black borders around the display image. When I pull up the catalyst control center on my computer I am able to adjust all of this stuff but on the one on my HTPC with the TV display I have no options. See images below.

  • VMWare Player pauses often

    - by pascal
    I'm using a 64bit Windows 8 inside vmplayer, with 2 virtual processor cores, virtual hard disk resides on a fast local disc and is not preallocated; host CPU is Intel i7 3770, should be capable of hardware virtualisation but I don't know if VMWare uses it; NAT networking; Sound card connected, USB connected, accelerated 3D graphics (NVidia 313.30 on host) My problem is, that the VM often pauses for a few seconds, and then speeds up for a few seconds to reach real time again. Time in the VM actually moves faster after the pause, for example all animations using timers speed up. When running, the vmware-vmx process shows ~150% CPU usage in top, but 0% when pausing (and D state i.e. waiting for IO). iotop shows normal disk writes from vmware-vmx threads, but during pauses, the flush kernel thread uses 99%. Are there some options to try so that VMWare doesn't wait for IO? I've tried a few things available from the GUI but the issue never went away…

  • Drawing map tiles for iPhone game

    - by user17778
    I'm working on a turn-based strategy game for the iPhone that has a hexagon-grid based map in it. I'm in the process of drawing up the actual tiles for the different landscapes (i.e. forest, grassland, etc.) and was wondering what program to draw the tile images in. I would assume Adobe Illustrator since a vector-based image may allow for smooth images even when the user is zoomed in really close. Is this right? Thanks!
