• Installed UBUNTU12.04 in Legacy, when changed to UEFI just runs the Terminal, not GUI

  - by jraulvc

  Well, I installed Ubuntu 12.04 in a Gateway NE 522 with Windows 8. First, I had to install it in Legacy mode, because in UEFI it would not run the bootable USB. In the Legacy mode it runs perfect. Once done that with help of the "Boot-Repair" I changed it to the UEFI and disabled the secure boot mode. GRUB runs fine but when I run ubuntu I get the following message: microcode: failed to load file amd-ucode/microcode_amd_fam16h.bin kvm: disabled by bios kvm: disabled by bios kvm: disabled by bios and then I just get access to the terminal. From there, I have already tried with reinstalling unity and gmd. When I try to install amd64-microcode the same error ocurrs ( microcode: failed to load file amd-ucode/microcode_amd_fam16h.bin ) by the "updating the microcode on all online processors..." phase of the installation. Can somebody tell me how can I recover the graphical interphase of ubuntu from the terminal? Thanks a lot

• jQuery 2.0 drops support for legacy IE (IE6, IE7, IE8)

  - by Renso

  Originally posted on: http://geekswithblogs.net/renso/archive/2013/10/31/jquery-2.0-drops-support-for-legacy-ie-ie6-ie7-ie8.aspxjQuery upgrades may not be as reverse compatible as you may think. Starting from version 2 of jQuery, IE6, IE7 and yes also IE8 will no longer be supported. These are now considered legacy browsers. You will need to stop any upgrades to jQuery until your SLA states that IE8 is no longer supported and remain in jQuery 1.9.Some of the reasons for not supporting IE8 and before:- Remove all the code clutter in the jQuery library with code that has to deal with IE browser compatibility issues between IE6, 7 and 8 and the newer IE versions, the latter being more compliant.- IE6 and 7 may have fallen to below 2% generally, that does not mean that that is true for your client base. In the oil and gas industry some clients are years behind and you may have 50% or more of clients remain on IE8 or older for the foreseeable future.- The difference between browser engines has become almost negligible, as it should be. So one of the greatest goals of jQuery to abstract that out for developers is no longer needed, for most part anyway. - CSS3 features like animations basically replace the need for jQuery’s 2.0 animations and effects.If the need is still there to support IE8 or before, but you also want to upgrade, then use conditional comments:<!--[if lt IE 9]>    <script src="jQuery-1.9.0.js"></script><![endif]--><!--[if gte IE 9]><!-->    <script src="jQuery-2.0.0.js"><</script><!--<![endif]-->

• Working with legacy data

  - by John Paul Cook

  We encounter legacy data as a part of life. Colleges and universities have transcript records dating back decades or even centuries. Real estate property records in the United States go as far back as Spanish and British land grants in the 1500s. Very old records are completely paper based and may be completely manually prepared, perhaps typed on a typewriter or written in longhand with a quill pen. How long should transcripts be retained? Nola Ochs graduated from college at age 95 (can you imagine...(read more)

• Connecting Windows 7 to legacy Linux Samba share

  - by bconlon

  I have had to rebuild my Windows 7 PC and all has gone fairly well until I tried to connect to a Samba share on a legacy Linux box running Redhat 8. No matter what combination of domain / user /password I would just see the same message of: "The specified network password is not correct." This is a misleading error, very annoying and a little confusing until I found a hint that Windows 7 default authentication was not supported on older Samba implementations. I guess I figured this out once before as it used to work before the rebuild! Anyway here is the solution: 1. Control Panel->System and Security->Administrative Tools->Local Security Policy (or run secpol.msc). 2. Select Local Policies->Security Options->Network security: LAN Manager authentication level. 3. Select 'Send LM and NTLM - use NTLMv2 session security if negotiated' and click OK. #

• Bringing in New Architecture During Maintenance on Legacy Systems

  - by Mike L.

  I have been tasked with adding some new features to a legacy ASP.NET MVC2 project. The codebase is a disaster and I want to write these new features with some thought behind the implementation and not just throw these new features into the mess. I would like to introduce things like dependency injection and the orchestrator pattern; just to the code that I am going to write. I don't have enough time to try to refactor the entire system. Is it OK to not be consistent with the rest of the codebase and add new features following different design principles? Should I not introduce new patterns and just get the features implemented? I feel like it might be confusing to the next person to see parts of the system using a design that other parts are not following.

• BCM4306, b43 legacy driver installed, but "firmware missing" error

• Tron: Legacy, 3D goggles, and embedded UA

  - by Roger Hart

  The 3D edition of Tron: Legacy opens with embedded user assistance. The film starts with an iconic white-on-black command-prompt message exhorting viewers to keep their 3D glasses on throughout. I can't quote it verbatim, and at the time of writing nor could anybody findable with 5 minutes of googling. But it was something like: "Although parts of the movie are 2D, it was shot in 3D, and glasses should be worn at all times. This is how it was intended to be viewed" Yeah - "intended". That part is verbatim. Wow. Now, I appreciate that even out of the small sub-set of readers who care a rat's ass for critical theory, few will be quite so gung-ho for the whole "death of the author" shtick as I tend to be. And yes, this is ergonomic rather than interpretive, but really - telling an audience how you expect them to watch a movie? That's up there with Big Steve's "you're holding it wrong" Even if it solves the problem, it's pretty arrogant. If anything, it's worse than RTFM. And if enough people are doing it wrong that you have to include the announcement, then maybe - just maybe - you've got a UX and/or design problem. Plus, current 3D glasses are like sitting in a darkened room, cosplaying the lovechild of Spider Jerusalem and Jarvis Cocker. Ok, so that observation was weirder than it was helpful; but seriously, nobody wants to wear the glasses if they don't have to. They ruin the visual experience of the non-3D sections, and personally, I find them pretty disruptive to the suspension of disbelief. This is an old, old, problem, and I'm carping on about it because Tron is enjoyable mass-market slush. It's easier for me to say "no, I can't just put some text on it. It's fundamentally broken, redesign it." in the middle of a small-ish, agile, software project than it would be for some beleaguered production assistant at the end of editing a $200 million movie. But lots of folks in software don't even get to do that. Way more people are going to see Tron, and be annoyed by this, than will ever read a technical communication blog. So hopefully, after two hours of being mildly annoyed, wanting to turn the brightness up, and slowly getting a headache, they'll realise something very, very important: you just can't document your way out of a shoddy UI.

• Why does Joomla debug show 446 queries logged and 446 legacy queries logged?

  - by Darye

  I have been called in to fix the performance of a Joomla site that was already setup. I look at the debug output and it shows the same queries twice, once for queries logged and again for legacy queries logged. My guess is that it is actually running the same queries twice make for just under 900 queries per page (hope I am wrong) The Legacy plugin is disabled, so Legacy mode is not on at all. The site uses VirtueMart as well (which BTW isn't working properly if the cache in the Global Config is turned on) Besides the fact that I don't think it should be running 446 queries anyway (sometimes even up to 650 per page ), has anyone every experienced this issue, and where would I look to fix this. Thanks

• Virtualization of Legacy API and co-existence with more modern API?

  - by Pharaun

  I don't mean for this question to be a flame bait but I'll be using Microsoft and their win32 API as a example of a legacy API. Now what I am wondering here is Microsoft is spending a lots of their money and energy in maintaining their legacy API, including all of the "glitches/bugs/workaround" that are needed to keep the API functioning the same. Now I'm aware that in Windows 7 they are providing a way for the customer to run their application in a "Windows XP" VM which would be one such way for them to start cleaning up their win32 API because they could then push all of the application into the "Windows XP" VM. So now what I am wondering is, is it possible to virtualization a legacy API in such way that an customer/program can still access and use it, yet at the same time be able to take advantage of the newer version/API? Because as far as I understand it, if the application is ran in the "Windows XP" VM, it won't be able to access any of the newer API/feature of Windows 7.

• Executing legacy MSBuild scripts in TFS 2010 Build

  - by Jakob Ehn

  When upgrading from TFS 2008 to TFS 2010, all builds are “upgraded” in the sense that a build definition with the same name is created, and it uses the UpgradeTemplate  build process template to execute the build. This template basically just runs MSBuild on the existing TFSBuild.proj file. The build definition contains a property called ConfigurationFolderPath that points to the TFSBuild.proj file. So, existing builds will run just fine after upgrade. But what if you want to use the new workflow functionality in TFS 2010 Build, but still have a lot of MSBuild scripts that maybe call custom MSBuild tasks that you don’t have the time to rewrite? Then one option is to keep these MSBuild scrips and call them from a TFS 2010 Build workflow. This can be done using the MSBuild workflow activity that is avaiable in the toolbox in the Team Foundation Build Activities section: This activity wraps the call to MSBuild.exe and has the following parameters: Most of these properties are only relevant when actually compiling projects, for example C# project files. When calling custom MSBuild project files, you should focus on these properties: Property Meaning Example CommandLineArguments Use this to send in/override MSBuild properties in your project “/p:MyProperty=SomeValue” or MSBuildArguments (this will let you define the arguments in the build definition or when queuing the build) LogFile Name of the log file where MSbuild will log the output “MyBuild.log” LogFileDropLocation Location of the log file BuildDetail.DropLocation + “\log” Project The project to execute SourcesDirectory + “\BuildExtensions.targets” ResponseFile The name of the MSBuild response file SourcesDirectory + “\BuildExtensions.rsp” Targets The target(s) to execute New String() {“Target1”, “Target2”} Verbosity Logging verbosity Microsoft.TeamFoundation.Build.Workflow.BuildVerbosity.Normal Integrating with Team Build   If your MSBuild scripts tries to use Team Build tasks, they will most likely fail with the above approach. For example, the following MSBuild project file tries to add a build step using the BuildStep task:   <?xml version="1.0" encoding="utf-8"?> <Project ToolsVersion="4.0" xmlns="http://schemas.microsoft.com/developer/msbuild/2003"> <Import Project="$(MSBuildExtensionsPath)\Microsoft\VisualStudio\TeamBuild\Microsoft.TeamFoundation.Build.targets" /> <Target Name="MyTarget"> <BuildStep TeamFoundationServerUrl="$(TeamFoundationServerUrl)" BuildUri="$(BuildUri)" Name="MyBuildStep" Message="My build step executed" Status="Succeeded"></BuildStep> </Target> </Project> When executing this file using the MSBuild activity, calling the MyTarget, it will fail with the following message: The "Microsoft.TeamFoundation.Build.Tasks.BuildStep" task could not be loaded from the assembly \PrivateAssemblies\Microsoft.TeamFoundation.Build.ProcessComponents.dll. Could not load file or assembly 'file:///D:\PrivateAssemblies\Microsoft.TeamFoundation.Build.ProcessComponents.dll' or one of its dependencies. The system cannot find the file specified. Confirm that the <UsingTask> declaration is correct, that the assembly and all its dependencies are available, and that the task contains a public class that implements Microsoft.Build.Framework.ITask. You can see that the path to the ProcessComponents.dll is incomplete. This is because in the Microsoft.TeamFoundation.Build.targets file the task is referenced using the $(TeamBuildRegPath) property. Also note that the task needs the TeamFounationServerUrl and BuildUri properties. One solution here is to pass these properties in using the Command Line Arguments parameter:   Here we pass in the parameters with the corresponding values from the curent build. The build log shows that the build step has in fact been inserted:   The problem as you probably spted is that the build step is insert at the top of the build log, instead of next to the MSBuild activity call. This is because we are using a legacy team build task (BuildStep), and that is how these are handled in TFS 2010. You can see the same behaviour when running builds that are using the UpgradeTemplate, that cutom build steps shows up at the top of the build log.

• fglrx-legacy-driver not seeing Radeon HD 4650 AGP

  - by Rocket Hazmat

  I am running Debian Squeeze on an old Dell Dimension 8300 box. It has an AGP Radeon HD 4650 card. I use this machine to mine bitcoins, and today I noticed that the machine had rebooted! My precious uptime! Anyway, my miner wouldn't start, so I figured might as well update my graphics driver, maybe that would fix the issue. I went to amd.com and downloaded the newest driver (12.6 legacy), but after installing it, aticonfig gave an error: aticonfig: No supported adapters detected I uninstalled the driver and figured I'd try to install it from apt. AMD has dropped support for the HD 4000 series in fglrx, forcing me to use fglrx-legacy-driver (currently only in experimental). In order to install this, I had to update libc6 (and some other important packages, like gcc), I had to use their wheezy versions. I finally got fglrx-legacy-driver installed, but I still got: aticonfig: No supported adapters detected Why isn't the driver finding my video card? I have a hunch it has something to do with the fact that it's an AGP video card. Here is the output of lspci -v (why does it say Kernel driver in use: fglrx_pci?): 01:00.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI RV730 Pro AGP [Radeon HD 4600 Series] (prog-if 00 [VGA controller]) Subsystem: Advanced Micro Devices [AMD] nee ATI Device 0028 Flags: bus master, 66MHz, medium devsel, latency 64, IRQ 16 Memory at e0000000 (32-bit, prefetchable) [size=256M] I/O ports at de00 [size=256] Memory at fe9f0000 (32-bit, non-prefetchable) [size=64K] Expansion ROM at fea00000 [disabled] [size=128K] Capabilities: [50] Power Management version 3 Capabilities: [58] AGP version 3.0 Kernel driver in use: fglrx_pci EDIT: fglrx 12.4 seems to work. Thing is, since I am on kernel 3.2, I need to apply this patch to common/lib/modules/fglrx/build_mod/firegl_public.c. I thought ATI dropped support for the 4xxx series after 12.4. Why doesn't 12.6 legacy work?

• Scheduled Deprecation of Legacy Obligation Features

  - by Wes Curtis

  The Obligation object in ETPM includes some functionality and tables that, to our knowledge, are not being used by customers and implementers are this time.  Removing this logic and the related tables should benefit the performance of and simplify logic executed during Obligation maintenance processing. The Release Notes included with ETPM v2.3.1 announced that the product plans to deprecate the functionality on Obligation for Contract Terms, Contract Quantities, Tax Exemptions, Terms & Conditions and Obligation Type Start Options.  Our plan is to remove this functionality in the next release of ETPM. We have already confirmed with most project teams that these features are not being used so the deprecation should have no impact on existing designs or process. If you think your project may be impacted by this deprecation, please review any Business Object that has been created for the Obligation maintenance object to make sure that no elements are being defined for any of the following child tables: -          CI_SA_CONTERM -          CI_SA_CONT_QTY -          CI_TOU_CONT_VAL -          CI_SA_TC   As part of this deprecation, the following administrative tables are being removed along with their related metadata: -          Contract Quantity Type -          Tax Exempt Type -          Terms and Conditions Please contact myself or the Oracle Tax Product Management team if your implementation has actually used these objects in their designs. We can discuss options to mitigate impacts of this planned deprecation.  We will continue to announce planned deprecations in the Release Notes for each release and will contact project teams ahead of time to confirm that these deprecations will have little to no impact on our customers.

• Radeon HD 2000, 3000, 4000 on 12.10 Quantal: fglrx (legacy) 12.6 unsupported, what to do?

  - by Andrew Mao

  After upgrading to 12.10 quantal, the packaged version of fglrx no longer works. I discovered that this is because there is a separate 'legacy' fglrx driver for the HD 2k-4k series cards, but it is incompatible with the xorg server on 12.10. This is the most current version of the driver for HD 2000 through HD 4000 series cards. You can't use the non-legacy fglrx driver, but you can use the open-source radeon driver if you prefer your WM compositing to be laggy and your YouTube videos to play like they would on a Pentium MMX series: http://support.amd.com/us/kbarticles/Pages/catalyst126legacyproducts.aspx Usually this driver can be installed in the following way, necessary because apt-get install fglrx would pull in the non-legacy driver: wget http://www2.ati.com/drivers/legacy/amd-driver-installer-12.6-legacy-x86.x86_64.zip unzip amd-driver-installer-* sudo sh ./amd-driver-installer-*.run --buildpkg Ubuntu/quantal sudo dpkg -i fglrx*.deb sudo aticonfig --initial -f If you use a different version of fglrx (for example, a newer 12.9 that doesn't support those cards) then the final command will give you an error no supported hardware detected or something similar. However, everything works at this point and you will get a reasonable xorg.conf: ... other stuff Section "Device" Identifier "aticonfig-Device[0]-0" Driver "fglrx" BusID "PCI:1:5:0" EndSection ... other stuff At this point you're supposed to reboot and everything will be working with the fglrx driver. However, upon rebooting, you'll be treated to the following errors in Xorg.0.log when fglrx attempts to load: (EE) Failed to load /usr/lib/xorg/modules/drivers/fglrx_drv.so: /usr/lib/xorg/modules/drivers/fglrx_drv.so: undefined symbol: noXFree86DRIExtension Some searching around will show that this is a problem with the legacy ATI drivers not supporting xserver 1.13 or newer. (Arch Linux thread) ATI has released a fixed driver for its most recent (HD 5000 series or later) cards, but not for the 'legacy' cards yet. The non-legacy ATI drivers can't be used with the old cards. What should an Ubuntu user, using one of these HD 2000-4000 series cards, do? Wait for an updated 'legacy' ATI driver that properly works with xserver 1.13? Downgrade back to 12.04 Precise, which uses xserver 1.11? Try to downgrade xserver on 12.10 Quantal to 1.12, which could possibly break Unity and GNOME? Forced upgrade to HD 5000 series or later card? (Not possible with integrated graphics...) Some other 1337 action that fixes this problem painlessly?

• Finding a way to simplify complex queries on legacy application

  - by glenatron

  I am working with an existing application built on Rails 3.1/MySql with much of the work taking place in a JavaScript interface, although the actual platforms are not tremendously relevant here, except in that they give context. The application is powerful, handles a reasonable amount of data and works well. As the number of customers using it and the complexity of the projects they create increases, however, we are starting to run into a few performance problems. As far as I can tell, the source of these problems is that the data represents a tree and it is very hard for ActiveRecord to deterministically know what data it should be retrieving. My model has many relationships like this: Project has_many Nodes has_many GlobalConditions Node has_one Parent has_many Nodes has_many WeightingFactors through NodeFactors has_many Tags through NodeTags GlobalCondition has_many Nodes ( referenced by Id, rather than replicating tree ) WeightingFactor has_many Nodes through NodeFactors Tag has_many Nodes through NodeTags The whole system has something in the region of thirty types which optionally hang off one or many nodes in the tree. My question is: What can I do to retrieve and construct this data faster? Having worked a lot with .Net, if I was in a similar situation there, I would look at building up a Stored Procedure to pull everything out of the database in one go but I would prefer to keep my logic in the application and from what I can tell it would be hard to take the queried data and build ActiveRecord objects from it without losing their integrity, which would cause more problems than it solves. It has also occurred to me that I could bunch the data up and send some of it across asynchronously, which would not improve performance but would improve the user perception of performance. However if sections of the data appeared after page load that could also be quite confusing. I am wondering whether it would be a useful strategy to make everything aware of it's parent project, so that one could pull all the records for that project and then build up the relationships later, but given the ubiquity of complex trees in day to day programming life I wouldn't be surprised if there were some better design patterns or standard approaches to this type of situation that I am not well versed in.

• Getting Unity 3D working on legacy Nvidia card

  - by user69545

  I installed the latest nVIDIA drivers for my FX5500 card. I understand that the X server version does not officially support this driver or card but was wondering what I can do to get compiz running. I have researched for hours on this issue but cannot come up with an answer for myself. I might be doing all this for nothing but I wanted to at least try. Here is the output of my test: mike@mike-linux-box:~$ /usr/lib/nux/unity_support_test -p OpenGL vendor string: NVIDIA Corporation OpenGL renderer string: GeForce FX 5500/AGP/SSE2 OpenGL version string: 2.1.2 NVIDIA 173.14.35 Not software rendered: yes Not blacklisted: no GLX fbconfig: yes GLX texture from pixmap: yes GL npot or rect textures: yes GL vertex program: yes GL fragment program: yes GL vertex buffer object: yes GL framebuffer object: yes GL version is 1.4+: yes Unity 3D supported: no So I was wondering what is the "Not Blacklisted" test? Is this the Nouveau Blacklisting? nVIDIA driver did that automatically. Does this need to be removed? Any help would be appreciated. I just want to run compiz effects. Thanks.

• DDD / Layers and legacy systems

  - by CSM

  I have to refactor a complex C# app (many dialogs, mixed logic and so on). There is a part managing the communication with special hardware equipments (sending commands and receive data via asynchronous c# callbacks). The code is "spaghetti" with mixed UI/Logic/Communication/etc and my task is to split the layers in a DDD sense. So, to which layer belongs a callback driver routine? The callbacks are creating "bubbles" in the system, up to the UI layer and because of this I cannot enforce the essential principle that any element of a layer depends only on other elements in the same layer or on elements of the layers "beneath" it. Thank you in advance.

• Switching my legacy desktop back to Windows XP from Windows 7

  - by Kevin Shyr
