• Browser support for internal corporate tools

  - by adam

  We are on the verge of a conversion. For years, our company supported only IE for its internal (intranet) home-built tools. Since a few of our users are still on XP, which means IE only goes up to 8... a heavily JS / jQuery site wont even load! We have been in the process of converting to use Chrome instead, to make use of its javascript performance. But, it has now been suggested that we support all common browsers... internally for these tools. Which means more development time to scale-back some of these new applications, more time to test in all browsers, and we are already under staffed. Are there any good informational sites/posts out there, that already make this argument?

• 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 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.

• Project OpenPTK Release 2.1 Available

  - by Scott Fehrman

  The OpenPTK owners are pleased to announce that release 2.1 is available.  It has been "tagged" in the svn repository. See the download page for details.   This release is an update to version 2.0.  This release contains bug fixes, enhancements to existing capabilities, and new features.  The most notable change in this release is the use of maven, instead of ant, for the build process.  The adoption of maven has made the project more modular, reduced its download size (less bundled jar files) and will enable the future support of Project OpenPTK in a maven repository. For full details, see the OpenPTK version 2.1 Release Notes

• Ubuntu 12.04 using UEFI

  - by Daniel

  I want to upgrade my machine with a new Motherboard, RAM and Processor. I am planning on doing a clean install of Ubuntu 12.04. The Motherboard I want to use is an Asrock 970 Extreme4 which uses an AMI 32 MBit UEFI BIOS. My Question is, is there anything I have to watch out for during the installation process? Cause I have read that some people have trouble booting into ubuntu using a UEFI BIOS. Any advice? I don't want to spend all that money for the different parts only to find out that I can only use windows properly. Thanks in advance

• When is using stdio preferable to fstream?

  - by Karl Bielefeldt

  I work on a well-established, embedded C++ code base. We have been using a proprietary API to our filesystem. For better integration with third-party C libraries, we are currently in the process of implementing most of stdio.h and fcntl.h. I made what I thought was a non-controversial proposal that we should also implement the fstream class and encourage new C++ code to use it instead of the new (to our code base) C-style API. We already have the stdout parts of iostream available, although it is not widely used. Given a choice between using stdio and fstream, what are good reasons to choose stdio for embedded software development in C++?

• Is there a way to continue a partially finished MinGW build?

  - by vsz

  I am just trying to become familiar with MinGW (and with more complex command-line compiler tools) I have a really giant project to build, I successfully managed to generate the makefile with CMake, and started mingw. After more than an hour of hard work, and building dozens of libraries successfully, the build ended in an error. It seems I added an option in CMake which is not supported in my system. My problem is, I cannot figure out a way to just skip that library and continue with the build process. If I remove the option in CMake and start mingw again, it starts from the beginning and rebuilds everything, even those libraries which are already built.

• Who makes laptops for Ubuntu?

  - by Tim Lytle

  I'm looking for a laptop and would like to avoid the whole 'is this [specific configuration of hardware] compatible with Ubuntu?' process by finding a laptop manufactured with Ubuntu in mind. I know of system76, but are there any other manufacturers making laptops built to run a standard build of Ubuntu? I'm not counting Dell, as - from my experience - their 'Ubuntu' laptops/netbooks require their build, and because of that have their own set of compatibility issues. UPDATE: And as mentioned in the comments, Dell is no longer selling systems with Ubuntu to consumers.

• SEO: best way to deal with short lifetime URLs?

  - by Mike Norgate

  I am currently in the process of redesigning a job advert site and am trying to put a lot more effort into my SEO. My question is how should I deal with the URLs that point to job adverts when the advert expires. The options I have thought of so far are: Return a 404 error and redirect to a 404 page. Will it have an effect on ranking if there are a lot of URLs that return 404s after only being up for a few weeks? Redirect to job listing page - When the user requests a URL for an advert that has expired just redirect to the main job listing page. Show the advert but tell the user to has closed - Show the advert page but with a notification that the advert has closed. The issue I see with this is that the user will visit the page, see its closed and then leave the site again which would not be good for rankings

• Create Adventure Game Scene/Room/Backdrop from Real Photo

  - by Lyuben

  Is there a suitable software or a good tutorial for creating 2D rooms/scenery for adventure games from real photos? Is it possible to achieve good results by using photos, or the hand-drawn style will always be the best choice? Thank you! --- EDIT --- I want to clarify that I'm particularly interested in the art creation process, not on the environment in which to build games. I'm writing the game in Java for Android, but I don't think it matters. Also, I'm not trying to decide if the game will have photo realistic rooms or not - I want to achieve 2d pixelated, old-school style background scenes and I wonder if this can be made from photos, because I cannot draw them myself. For example, can I shoot a scene with my camera and then make it look something like the image in the following link: PIXEL ART FOREST I know that I cannot get the same quality as an absolutely hand-drawn pixel, but I'm looking for some decent technology/tutorial/software to make them somewhat similar.

• Fix hibernate on Thinkpad X60 with 12.04 Precise Pangolin

  - by ddaa

  I own a ThinkPad X60, hibernate used to work on 10.04 Lucid Lynx, but no longer works correctly on 12.04. I am aware of how to enable hibernate in Power Manager. The problem here is, in the default configuration, pm-hibernate works, but the system fails to resume correctly. There is no video glitch, black screen or other. The resume process just freezes on the Ubuntu splash boot after a few seconds of disk activity. Is there a way to fix the system configuration so hibernates works again?

• Is it possible to mod_rewrite BASED on the existence of a file/directory and uniqueID?

  - by JM4

  My site currently forces all non www. pages to use www. Ultimately, I am able to handle all unique subdomains and parse correctly but I am trying to achieve the following: (ideally with mod_rewrite): when a consumer visits www.site.com/john4, the server processes that request as: www.site.com?Agent=john4 Our requirements are: The URL should continue to show www.site.com/john4 even though it was redirected to www.site.com?index.php?Agent=john4 If a file (of any extension OR a directory) exists with the name, the entire process stops an it tries to pull that file instead: for example: www.site.com/file would pull up (www.site.com/file.php if file.php existed on the server. www.site.com/pages would go to www.site.com/pages/index.php if the pages directory exists). Thank you ahead of time. I am completely at a crapshot right now.

• 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…

• Security settings for this service require 'Basic' Authentication

  - by Jake Rutherford

  Had an issue calling WCF service today. The following exception was being thrown when service was called:WebHost failed to process a request. Sender Information: System.ServiceModel.ServiceHostingEnvironment+HostingManager/35320229 Exception: System.ServiceModel.ServiceActivationException: The service '/InteliChartVendorCommunication/VendorService.svc' cannot be activated due to an exception during compilation.  The exception message is: Security settings for this service require 'Basic' Authentication but it is not enabled for the IIS application that hosts this service..Ensured Basic authentication was indeed enabled in IIS before getting stumped on what actual issue could be. Turns out it was CustomErrors setting. Value was set to "off" vs "Off". Would have expected different exception from .NET (i.e. web.config parse exception) but it works now either way.

• Black screen after login, after Kubuntu upgrade from 13.04 to 13.10

  - by Soul Trace

  After upgrade from 13.04 to 13.10 I have troubles with Xorg - all boot process goes fine, but I have a black screen when Xorg starts (KDE starts, and I can hear AC adapter (dis)connect sounds). Trouble is in Xorg only, framebuffer console (ctrl-alt-f2) works fine, backlight turns on when I switch to console and turns off again after I switch back to X. All worked fine before release upgrade. I'm running AMD64 version of Kubuntu 13.10 on Samsung RV508 (Intel i915 graphic, no EFI) notebook. Xorg 1.14.3, kernel 3.11.0-12 UPDATE: I have tried to boot using old kernel (3.8.0-13) and now it's working fine with that kernel.

• Long term planning and agile?

  - by Ignite

  My team has recently went through the process of laying out a nearly one year plan for our direction of work. We have separated the plan into three phases and each phase will include a couple of launches. I wonder, from an agile point of you, is what we do wrong? I think it's not a bad idea, because we haven't spent too much time on designing anything but the first few steps and it's possible for us to change direction. At the same time it's nice that we don't act with only the near term in sight.

• How do you find partners for open source projects?

  - by static_rtti

  I've created a few open-source projects in the past, and had some success. The process was generally the following: I'd start alone, create something that works, promote it, and finally (maybe) get some contributions. I have less that to contribute to open-source now, but I still have ideas and can still code :) So I wonder if there is a place or a way to meet people (online), discuss ideas and design, and then start working together on the project? The reason I'm thinking about an online way to do this, with strangers, is that while I do have programmer friends, we only very rarely have the same needs and interests at the same time. It seems to me that it would be easier to find such in match in the online global community. Any insight?

• Web Platform Installer issues deploying Azure SDK 1.4 on refreshed systems.

  - by Enrique Lima

  Recently I have been doing quite a bit of testing on different means to deploy the Azure SDKs and such. After a very successful couple of systems, I started running into issues last night. Here is the problem, if I go to the Windows Azure Website, and go to Develop, then click on the SDK and Tools, then Get Tools & SDK, it launches the Web Platform Installer.  All seems well at that point, except it will go through the initial process, will find the SDK files for 1.4, but since the tools for Visual Studio are still 1.3, the location throws back a 404, which causes the Installer to fail.  NOTE:If you already had SDK 1.3 and the tools in place, it will go through. The fix is to go directly to the Microsoft Download Center location and download the files.  Here is the link … http://www.microsoft.com/downloads/en/details.aspx?FamilyID=7a1089b6-4050-4307-86c4-9dadaa5ed018

• How to calculate Sin function quicker and more precisely?

  - by user1297181

  I want to calculate y(n)=32677Sin(45/1024•n), where y is an integer and n ranges from 0 to 2048. How can I make this process quicker and more precisely? Now I want to show you a reference answer: Since Sin(a+b)=Sin(a)Cos(b)+Cos(a)Sin(b) And Cos(a+b)=Cos(a)Cos(b)-Sin(a)Cos(b). So I can store Sin(45/1024•1) andCos(45/1024•1) ` only.Then use this formula: Sin(45/1024•2)=Sin(45/1024•1+45/1024•1), Cos(45/1024•2)=Cos(45/1024•1+45/1024•1), .... `Sin(45/1024•n)=Sin(45/1024•(n-1)+45/1024•1) `, `Cos(45/1024•n)=Cos(45/1024•(n-1)+45/1024•1) `, This way maybe quicker without storing large array.

• Using google maps as an input method

  - by Vasiliy Sharapov

  I'm wondering if it's possible to use gmaps pretty much as a type of input. Normally for Location a user has to enter: street address town/city state/province postal code country This seems too clunky to me, does anyone here know of a more elegant process? My perfect address-entering interface is a gmaps search bar with a map under it. When the user clicks a marker instead of a speech bubble containing location information they get one containing a submit button or equivalent. I'm not sure anything like this has been implemented before.

• Dealing with FUD? [on hold]

  - by Pawel G.

  How to interact with colleague who will happily talk about a thing, but from the way he talk about it, it becomes clear, that he does not fully understand some underlying concepts - but at the same time is not that kind of personality, that would ask for clarification or explanation (maybe because it is sign of weakness). There is difficulty involved in such a situation, since such people will demand to be consulted in a decision process, but instead of brainstorming solutions one will need to neutralize the diffusion of the concepts first, and when this is done time is already up and solution cannot be brainstormed any more. Maybe FUD is not the correct acronym, maybe DIS, Diffusion, Indifference, Surety.
