• Where to find Hg/Git technical support?

  - by Rook

  Posting this as a kind of a favour for a former coleague, so I don't know the exact circumstances, but I'll try to provide as much info as I can ... A friend from my old place of employment (maritime research institute; half government/commercial funding) has asked me if I could find out who provides technical support (commercial) for two major DVCS's of today - Git and Mercurial. They have been using VCS for years now (Subversion while I was there, don't know what they're using now - probably the same), and now they're renewing their software licences (they have to give a plan some time in advance for everything ... then it goes "through the system") and although they will be keeping Subversion as well, they would like to justify beginning of DVCS as an alternative system (most people root for Mercurial since it seems simpler; mostly engineers and physicians there who are not that interested in checking Git repos for corruption and the finer workings of Git, but I believe any one of the two could "pass") - but it has to have a price (can be zero; no problem there) and some sort of official technical support. It is a pro forma matter, but it has to be specified. Most of the people there are using one of the two already, but this has to be specified to be official. So, I'm asking you - do you know where could one go for Git or Mercurial technical support (can be commercial)? Technical forums and the like are out of the question. It has to work on the principle: - I have a problem. - I post a question with the details. - I get an answer in specified time. It can be "we cannot do that." but it has to be an official answer and given in agreed time. I'm sure by now most of you understand what I'm asking, but if not - post a comment or similar. Also, if you think of any reasons which could decide justification of introducing Git/Hg from an technical and administrative viewpoint, feel free to write them down also.

• iChat can't authenticate to Lion Server 10.7.2 [migrated]

  - by glenstorey

  I've enabled iChat and iCal Server through our local 10.7.2 Server which has DNS set up correctly. I can add the server account via a client's System Preferences (under other - Mac OS X server) and it authenticates with my shortname correctly. However, when I load iChat, I get this error message: Where the account is [email protected]. The password and username is correct. Console throws this error: 22/11/11 3:03:31.135 PM imagent: [Warning] XMPPConnection: Error: Error Domain=XMPPErrorDomain Code=105 "The operation couldn?t be completed. (XMPPErrorDomain error 105.)" UserInfo=0x7f81bbe2a3e0 {XMPPErrorText=service requested for unknown domain} DNS is set up correctly (it's working for Profile Management, Software Update Server and Web Services) but I can't get iChat to work correctly. How can I get clients to authenticate? FYI: It's probably worth noting that I get the exact same error messages when I use [email protected] instead of [email protected]. Also posted this question on Apple Discussion here.

• How do you author HDR content?

  - by Nathan Reed

  How do you make it easy for your artists to author content for an HDR renderer? What kinds of tools should you provide, and what workflows need to change, in going from LDR to HDR? Note that I'm not asking about the technical aspects of implementing an HDR renderer, but about best practices for creating materials and lighting in HDR. I've googled around a bit, but there doesn't seem to be much about this topic on the web. Can anyone point me to some good resources on this, or share their own experiences? Some specific points: Lighting - how can lighting artists pick HDR light colors? Do they have a standard LDR color picker and then a multiplier? Is the multiplier in gamma or linear space? Maybe instead of a multiplier it's a log-luminance? Or a physical brightness level, like the number of lumens? How will they know what multiplier/luminance/brightness is "correct" for a given light? Materials - how can texture artists make emissive color maps, such as neon signs, TV screens, skyboxes, etc? Can you paint one as a regular LDR (8-bit-per-channel) image and apply a multiplier (or log-luminance, etc.)? Are there cases where it's necessary to actually paint HDR images? If so, how do you go about this in Photoshop (or other software)?

• Bluetooth Issues Ubuntu 13.10

  - by Eduardo

  I have a bluetooth headset which works perfectly on Ubuntu 13.04. Now I update to 13.10, and here is what's happing: After installing blueman, bluetooth-suport, pulseaudio-module-bluetooth and so on, I can find my device, pair it and connect to the headset service. But the device does not appear on the Sound Settings, so I just can't select it as input/output device. In other words, it's connected but "useless". So, searching around for solutions, I found a software called stream2ip. With this I can connect the device and it appears on the Sound Settings, the sound plays on the device as well, but I microphone does not work, even when selected on the settings, also the A2DP option still not working. Stream2ip isn't a solution at all, I mean everything was working without it in the previous Ubuntu version. Maybe I'm missing something, and I hope someone could give me any hint. And formally, the question: How can I get the A2DP output option and the input working again, on the Ubuntu 13.10? Thanks!

• yum / rpm / make | When to use which one

  - by Saif Bechan

  I am new to Linux and am running CentOs. When I want to update or install certain software I came across three ways. Sometimes it's: yum install program rpm -i program.rpm wget program.tar.gz unpack ./configure make make install That last one is a real pain, esp when you come from windows where a program install is usually one click and then a nice guide. Now can someone please explain to me: Why are there so many different ways to do this? Which one do you recommend to use and why? Are there any other ways for installing programs?

• Thin virtual host [migrated]

  - by Adam Ryczkowski

  My work setup relies on old Windows XP. Now, when Windows XP isn't supported by new hardware, it's getting harder and harder to buy a notebook on which Windows XP can run natively with all essential hardware (wireless cards, graphics, sound etc). Since I don't expect my personal setup to turn away from Windows XP any time soon, I'm investigating the following trick: why not buy any decent hardware which Linux can fully utilize, and use it as a virtual host for a guest session with e.g. Windows XP. I like using hibernation, so I prefer this Linux to be as thin as possible, only enough to support VirtualBox, KVM or any other virtualization software. Question: Are there any "standard" ways to do this, like Linux distributions aimed specifically on being light virtualization host?

• How to "restart/repair" an USB port?

  - by Click Ok

  My laptop has two USB ports, but one is broken, so I use a USB hub in the other good USB port. In that USB hub, I use a mouse and keyboard. Suddenly, that USB port doesn't detect the mouse and the keyboard (even with the light of the hub is on), and the only solution that I found is restarting the laptop. But just some minutes and the keyboard and mouse goes undetected again... Is there some method, software, etc. to "restart/repair" the USB port without restarting the PC?

• How to use auto-discovery with iDRAC Enterprise?

  - by jwiz

  All I want to do is: have "auto discovery" enabled on my iDRAC enterprise at the factory rack the server, cable iDRAC to dhcp-enabled management network have the iDRAC DHCP, find the "Provisioning Server", and get updated with login credentials (for us to use with racadm, idrac webui, etc.) I don't need to do any configuring of the system, install OS, or anything else. I just want idrac to dhcp out of the box, and end up with an account that can be used to login. All the docs I can find on Dell's site refer to a "Provisioning Server", but I honestly can't tell if they have some reference product, or if they only have software that "integrates" with other vendor's existing management systems. I'd be happy to set up whatever is needed, I just can't find something that explicitly describes the process (only references to the fact that it is supported).

• How to search for a tester?

  - by MainMa

  As a freelance developer, a few times I tried to find some testers to be able to let them test my software/web applications. If I try to find them, it's because most of the customers are not intended to hire external testers and don't see why this can benefit to them, so products are UI-untested and buggy. I tried lots of things. Discussion boards for IT people, specific websites for people who search for a job. Every time I clearly precise that I'm looking for product testers. I completely failed to find anybody for this job. I found instead two types of people: Non IT people who try to qualify as testers, but don't have enough skills for that, and don't really know what testing is and how to do it, Programmers, who are skilled as programmers, but not as testers, and who mostly don't understand neither what testing is about (or think it's the same thing as code review, or it consists in writing unit tests). Of course, they submit general programmers resumes, where they describe their high experience in Assembler and C++, but don't tell anything about anything related to the job of a tester. What I'm doing wrong? Isn't it called "tester"? Is there at least a tester job, different from general programming job? Is there any precise requirement to require from each candidate which can eliminate non IT people and general programmers?

• How can I monitor network traffic in an all Mac home network?

  - by raiglstorfer

  I have an all Mac network consisting of an Airport Extreme, 1 MacPro, 1 Mac Mini, 2 MackBook Pros, 2 iPads, and 2 iPhones. The Mac Pro is connected directly to the Airport Extreme via Cat5 and the rest is all running via Wireless. Lately I've been getting prompted by Google to enter Capchas frequently. The message states that I might have software running on my network I'm not aware of. My wireless router is password protected using WPA2 Personal and I frequently change my password so I don't think someone is using the network from outside (but I've no way to confirm this). I'm looking for a relatively cheap (preferably open source) solution that would enable me to monitor and profile the network usage by machine and port. Can someone recommend a solution?

• SharePoint 2007 / 2010 Content Indexing &ldquo;The file reached the maximum download limit. Check that the full text of the document can be meaningfully crawled.&rdquo;

  - by Stacy Vicknair

  If you have large files in a content source that is being indexed by Sharepoint you might run into the following error message: “The file reached the maximum download limit. Check that the full text of the document can be meaningfully crawled.” This is usually caused because SharePoint’s MaxDownloadSize setting is set lower than the size of the file you are attempting to index. You can increase this value, restart the service then kick off a full crawl in order to fix this issue, but SharePoint 2007 and 2010 have different methods for accomplishing this task.   Sharepoint 2007 Open up the Registry editor and increase the MaxDownloadSize value to a number (in MB) higher than the largest file being indexed. You can find this at: HKEY_LOCAL_MACHINE\Software\Microsoft\Search\1.0\Gathering Manager After you increase the size, cycle the search service and kick off a full crawl of the content source in question.   Sharepoint 2010 With SharePoint 2010 you can use PowerShell via the Sharepoint 2010 Console in order to change the MaxDownloadSize. Execute the following commands to update the value: 1: $ssa = Get-SPEnterpriseSearchServiceApplication 2: $ssa.SetProperty(“MaxDownloadSize”, <new size in MB>) 3: $ssa.Update()   References: http://support.microsoft.com/kb/287231 http://blogs.technet.com/b/brent/archive/2010/07/19/sharepoint-server-2010-maxdownloadsize-and-maxgrowfactor.aspx   Technorati Tags: SharePoint,WSS,MaxDownloadSize,Search

• Why can't the Adobe Flash player send key strokes it doesn't handle to the browse in which it is run

  - by jim.e.clark

  I'm a heavy web user that uses the address bar constantly while browsing the web. I often use Ctrl + T to open a new tab or Ctrl + D to move focus to the address bar so it is very annoying that these shortcut keys do not work when a Flash object has focus on the active browser tab. I would happily give up all keyboard handling in the Flash Player in exchange for having keystrokes sent to the browser. In fact, as someone who has worked in software development for over 15 years it is hard to believe that Flash doesn't pass common browser shortcut keys to the browser or have an option to do so. So my question is this: Am I missing some option, some Flash shortcut key or some Firefox add-on that will alleviate my suffering?

• How can I configure a Linksys EA4500 + usb printer for network printing (without connect cloud)

  - by Larry Kyrala

  The documentation and classic firmware (2.0.37) for Cisco's Linksys EA4500 is a bit sparse on setup details. It says I can connect a USB-printer, but then goes on to try to sell "Connect Cloud" remote management software. I don't want that. I just want to know how to set this up with the existing advanced firmware. Is it possible? AFAIK, to setup a IPP or LDP printer, there is usually some kind of queue configuration on the server (i.e. the ea4500 in this case), but I can't find it in the firmware. I also have been unable to find any existing protocols from win7 or mac osx. (windows network share, IPP/LDP etc.) I'm curious if I need to have the "Storage" accounts active and connect to my router either via the local IP or router name. There's a lot of unknowns here; it would help to know how this particular router actually works.

• Running Non-profit Web Applications on Cloud/Dedicated Hosting [closed]

  - by cillosis

  Possible Duplicate: How to find web hosting that meets my requirements? I often times build web applications purely because I enjoy it. I like building useful tools or open source applications that don't come with a price tag. That being said, many of these applications can be quite complex requiring services beyond shared hosting (ex. specific PHP extensions). This leaves me with two options: Make the web application less complex and run on shared hosting. Fork out money for cloud or dedicated/VPS hosting. Considering the application is free (I don't make money off of it intentionally), the money for hosting comes out of my own pocket. I know I am not alone in this sticky situation. So the question is, what are the hosting options that provide more advanced features such as shell access via SSH, ability to install specific software/extensions (ex. if I wish to use a NoSQL DB such as Redis, MongoDB, or Cassandra), etc., at a free or low price point? I know free usually equates to bad/unreliable hosting -- but it's not always the case. There are a couple providers with free plans I know of: Amazon EC2 - Free micro-instance for 1 year AppHarbor - Cloud based .NET web application hosting w/ free plan. What else is available for hosting of non-profit applications?

• Microsoft Excel 2013

  - by Dan LaMoreaux

  We use a spreadsheet as our timecards. The template is stores on the server with links to it on the individual Desktops. I am trying to figgure out the VB so that wnen the cell for username (B5) is blank, the VB will place next sundays date in (B7). After the user enters thier name in B5, I need it to not change B7 again. If I use a formula in B7 "=IF(B5="",TODAY()+8-WEEKDAY(TODAY()),B7)" i need to enable the curcular calcualtions, which don't follow from the template to the spreadsheet, thus causing errors for every individual. Corporate says that they need to be in Excel, because of the import software. Otherwise I'd use Word and the "CreateDate" function. I've been trying to learn the VB to do it, but I was hoping that soem expert could whip out the code in 5 min. flat and just let me disect it.

• Reimage PC: Myth or Fact to speeding up a slow PC?

  - by sunpech

  I have a 4-5 year old PC running Windows XP for software development at work. It struggles to run all development tools I need at the same time. Management feels I need to reimage my computer to "speed it up". The last time it was imaged was about 3 years ago. What resources books, websites, blogs, articles, etc are out there that supports/debunks this well known belief that reimaging an old PC running Windows XP will make it faster once again? A resource I remember reading is from Lifehacker.com: Windows Maintenance Tips: The Good, Bad And Useless

• Windows 7 USB power lose after a few seconds / minutes

  - by Stefan Dunn

  My friend's computer has a problem where the USB ports causes problems with the power of some devices connected to the computer. The USB mouse has no problems, however the Wireless Adapter looses power after around 20 seconds of use and USB Flash Drives cause the computer to either freeze, lose power (and become unresponsive) or become disconnected (still shown in Device Manager, but not in My Computer) when trying to transfer any type of file to / from the computer. I have a suspicion it's the Motherboard but could it also be a Software problem? Tried a new case, RAM, CPU and GFX Card which had no effect. The problem occurs on both the Front USB and Back (Motherboard) USB Ports. UPDATE: Tried the USB devices with an Ubuntu Live CD and they work fine, could this mean it's a problem with Windows (x64)?

• Is it me or is developing web based data entry GUIs a big pain?

  - by GregH

  Maybe it's me or maybe it isn't. I don't have a huge amount of experience of developing web based data entry software but do have some. I used to do it quite a bit years ago. Used to use Oracle Forms, Visual Studio, various 4th generation languages, and performing the user interface layout used to be a snap. Now doing the user interface for developing web applications seems to be a huge pain in the rear. Just trying to get text entry fields and widgets to go where they are supposed to go on the screen is a total pain. You have to know Javascript, CSS, JQuery, HTML, etc. There must be an easier way to develop data entry forms that produce the needed underlying code for a web page. Maybe I'm just not looking in the right place. There must be some WYSIWYG GUI development tools for the web for developing data entry forms out there. Anybody know of any?

• Reinstalled Windows XP Home, shows as XP Pro, 'invalid' errors

  - by jan

  We reinstalled Windows XP Home after hard drive crash. The system now shows as XP Pro and we're constantly getting 'invalid software' popups, images show in solid black. We called Microsoft, they said the serial number is valid etc. We're assuming that the pop ups are because that it is now XP Pro instead of Home. Or could it be something else? Or how can we determine what the issue is in order to correct it? Thanks for any advice on this. jb

• foswiki: use genPDF extension with topic templates?

  - by Mica

  I have a foswiki installation for keeping ISO and other documents. I would like to create a PDF from each page. How can I create a topic template with different headers and footers for each topic template? More info: When a user creates a new topic, they can choose a template. I've made several templates for Functional and Programming specs. The functional spec and programming spec require different document numbers. I would like for the software engineers to be able to create a new topic, choose the template, then be able to generate a PDF from the wiki page, pulling the appropriate document number, and some other text into the headers and footers. I am not very familiar, and haven't been able to find any examples on doing this. Any help would be appreciated!

• What is your unique programming problem-solving style? [closed]

  - by gcc

  Everyone has their own styles and technique for approaching and solving real world problems. These distinguish us from other people or other programmers. (Actually, I think it make us more desirable as programmers and improves computer science) To improve, we read a lot of books; for example, programming style, how to solve problems, how to approach problems, software and algorithms, et al. Can I learn your technique? In other words, if someone gives you a problem, at first step, what are you doing to solve it? I want learn the style in which you approach, analyze, and solve a problem. EDIT: every programmer is a unique instance; each of us approach problems and converge on solutions in our own... idiomatic manner. This manner is sometimes a quirk of training, a bias of tools, but often it is an insightful nugget, a little golden hammer that cracks nuts just slightly faster then others. When answering, give your general approaches but also take a moment to identify how you look at things in ways that your peers do not. Let's call this your Unique Solving Perspective, or USP.

• Virtualbox PXE Boot Failing with a Windows Server 2008 R2 Server

  - by Vbitz

  Some fast help on this would be good, I have been on this problem for 14 hours. In a Virtualbox test environment I have 2 virtual machines networked together using a internal network (no traffic runs though the host, it is all at a software level). One is a fresh client with 512mb of ram and a dual core set-up, the other is the server with 1.5GB of ram and running server 2008 r2. The server is configured as a dns server, dchp server, domain controller and also serves PXE booting though WDS (Windows Deployment Services). Both machines can see each other and I am able to start a network boot. The issue comes at the second to last stage of the pre windows PE install. On TFTP download of boot.sdi it starts it but stops during the boot process.
