  • Have I bricked my Sun V20z?

    - by David Mackintosh
    I have a small pile of Sun V20z computers. I was trying to update the SP and BIOS firmwares in order to bring them all up to the same standard -- mostly to get the updated (ie actually useful) SP functionality, and figured that I would just do the BIOS while I was at it. For three of the four computers, it worked perfectly. However after the BIOS update, the fourth system won't boot. I did this: batch05-mgmt $ sp get mounts Local Remote /mnt 10.16.0.8:/export/v20z batch05-mgmt $ platform set os state update-bios /mnt/sw_images/platform/firmware/bios/V1.35.3.2/bios.sp This command may take several minutes. Please be patient. Bios started Bios Flash Transmit Started Bios Flash Transmit Complete Bios Flash update Progress: 7 Bios Flash update Progress: 6 Bios Flash update Progress: 5 Bios Flash update Progress: 4 Bios Flash update Progress: 3 Bios Flash update Progress: 2 Bios Flash update Progress: 1 Bios Flash update complete batch05-mgmt $ platform set power state on This command may take several minutes. Please be patient. After an hour of waiting, it still won't start. The chassis powers on, but beyond the fans spinning up and the hardware POST of the drives, nothing appears to happen. So if I try to re-flash the BIOS (on the theory that maybe something went wrong): batch05-mgmt $ platform set os state update-bios /mnt/sw_images/platform/firmware/bios/V1.35.3.2/bios.sp This command may take several minutes. Please be patient. Bios started Error. The operation timed out. Have I bricked it?

  • Why does my Intel HDA onboard sound card not have a "Mix" device / channel?

    - by Hanno Fietz
    I want to be able to record what my sound card outputs on the speakers / headphones. This question is all over the interwebs again and again, and there seem to be two outcomes: in your selection of audio input devices, there's a device called "Stereo Mix", or similar, which is the "loopback" device for audio. Choose that in your recording tool and you're done. there's no such device and only speculative posts about why that may be. Now, I'm using ALSA and an Intel HDA chipset on my mainboard under Kubuntu Karmic. I have some 5-10 output channels and "Mic", "Front Mic" and "Line" for input. All of those are available in KMix, Audacity and other software. No "loopback" / "Mix" / whatever. Do I have to get some driver / kernel module set up ALSA in some way set up my system configuration in some way use a software solution (such as JACK) I had a look at JACK, and found it rather hard to understand, it's either an expert tool or just clumsy, I couldn't say. At least, I wasn't able to figure out how to achieve what I wanted. One of my problems seems to be that I don't understand where and how the mixing happens. Are there sound cards which just aren't able to do it? Why does the sound card matter at all, since I could in theory grab the data stream at some point before it goes to the hardware, right?

  • Good Delphi Blogs?

    - by Andreas Rejbrand
    I just saw http://pages.cs.wisc.edu/~rkennedy/ which appears to be a very interesting in-depth blog about the Delphi programming language, compiler, and IDE. At the more basic level we also have the About site, and DelphiBasics. You can also have fun for a few minutes at http://www.scalabium.com/faq/dc_tips.htm. What are the most interesting blogs and sites devoted to Delphi? I am in particular interested in content at the advanced level.

  • Play an audio file using RemoteIO and Audio Unit

    - by NeilMonday
    I am looking at Apple's 'aurioTouch' example for the iPhone and I would like to play an mp3 or wav instead of using the built in mic. I am very new to the audio portion of iPhone programming, but I think I need to modify the SetupRemoteIO(...) function and replace the AudioComponent named 'comp' with a custom AudioComponent that plays a file. Basically I want the app to function exactly the same as the original, but with an audio file as the input instead of the mic.

  • Reorder cells in a UITableView without displaying a "delete" button

    - by iter
    I want to be able to reorder cells in a table, but not to delete or insert them. I want a picture like this: This image appears in Apple's Table View Programming Guige, but the code samples there produce a table with red "delete" buttons when the table goes into editing mode. I can set editingStyleForRowAtIndexPath to UITableViewCellEditingStyleNone and that makes the delete buttons go away, but the rows are still indented as if to make room for these buttons.

  • Converting a WPFToolkit DataGrid from 1D list to 2D matrix

    - by user61073
    Hello - I am wondering if anyone has attempted the following or has an idea as to how to do it. I have a WPFToolkit DataGrid which is bound to an ObservableCollection of items. As such, the DataGrid is shown with as many rows in the ObservableCollection, and as many columns as I have defined in for the DataGrid. That all is good. What I now need is to provide another view of the same data, only, instead, the DataGrid is shown with as many cells in the ObservableCollection. So let's say, my ObservableCollection has 100 items in it. The original scenario showed the DataGrid with 100 rows and 1 column. In the modified scenario, I need to show it with 10 rows and 10 columns, where each cell shows the value that was in the original representation. In other words, I need to transform my 1D ObservableCollection to a 2D ObservableCollection and display it in the DataGrid. I know how to do that programmatically in the code behind, but can it be done in XAML? Let me simplify the problem a little, in case anybody can have a crack at this. The XAML below does the following: * Defines an XmlDataProvider just for dummy data * Creates a DataGrid with 10 columns o each column is a DataGridTemplateColumn using the same CellTemplate * The CellTemplate is a simple TextBlock bound to an XML element If you run the XAML below, you will find that the DataGrid ends up with 5 rows, one for each book, and 10 columns that have identical content (all showing the book titles). However, what I am trying to accomplish, albeit with a different data set, is that in this case, I would end up with one row, with each book title appearing in a single cell in row 1, occupying cells 0-4, and nothing in cells 5-9. Then, if I added more data and had 12 books in my XML data source, I would get row 1 completely filled (cells covering the first 10 titles) and row 2 would get the first 2 cells filled. Can my scenario be accomplished primarily in XAML, or should I resign myself to working in the code behind? Any guidance would greatly be appreciated.

  • C++ vs Matlab vs Python as a main language for Computer Vision Postgraduate

    - by Hough
    Hi all, Firstly, sorry for a somewhat long question but I think that many people are in the same situation as me and hopefully they can also gain some benefit from this. I'll be starting my PhD very soon which involve the fields of computer vision, pattern recognition and machine learning. Currently, I'm using opencv (2.1) C++ interface and I especially like its powerful Mat class and the overloaded operations available for matrix and image seamless operations and transformations. I've also tried (and implemented many small vision projects) using opencv python interface (new bindings; opencv 2.1) and I really enjoy python's ability to integrate opencv, numpy, scipy and matplotlib. But recently, I went back to opencv C++ interface because I felt that the official python new bindings were not stable enough and no overloaded operations are available for matrices and images, not to mention the lack of machine learning modules and slow speeds in certain operations. I've also used Matlab extensively in the past and although I've used mex files and other means to speed up the program, I just felt that Matlab's performance was inadequate for real-time vision tasks, be it for fast prototyping or not. When the project becomes larger and larger, many tasks have to be re-written in C and compiled into Mex files increasingly and Matlab becomes nothing more than a glue language. Here comes the sub-questions: For postgrad studies in these fields (machine learning, vision, pattern recognition), what is your main or ideal programming language for rapid prototyping of ideas and testing algorithms contained in papers? For postgrad studies, can you list down the pros and cons of using the following languages? C++ (with opencv + gsl + svmlib + other libraries) vs Matlab (with all its toolboxes) vs python (with the imcomplete opencv bindings + numpy + scipy + matplotlib). Are there computer vision PhD/postgrad students here who are using only C++ (with all its availabe libraries including opencv) without even needing to resort to Matlab or python? In other words, given the current existing computer vision or machine learning libraries, is C++ alone sufficient for fast prototyping of ideas? If you're currently using Java or C# for your postgrad work, can you list down the reasons why they should be used and how they compare to other languages in terms of available libraries? What is the de facto vision/machine learning programming language and its associated libraries used in your university research group? Thanks in advance.

  • Tasks not appearing in Mac Outlook 2011

    - by Tama
    My current workplace uses Macs and my old workplaces used Windows. In my old workplaces I heavily used Outlook's Task functionality to manage my workload. I understand that the Task functionality in Outlook 2011 for Mac is heavily limited so I was very pleased to find this useful "how-to" on making the most of Tasks. My problem is that my tasks don't appear in the Task folder, or anywhere else for that matter. Even if I search for a the title of a task I've recently found I still can't find them. After some Googling I found this forum thread that suggests it may be a problem with the Outlook database, which points to a Microsoft KB. So I went through all of the recommended steps on rebuilding/ adding a new identity using the "Microsoft Database Utility" - the theory being that if I create a new identity I can test the task creation using a "blank slate" identity. When I change the default identity to my newly created identity using the Microsoft Database Utility (have to restart the computer) Task creation still doesn't work. Any ideas appreciated, I really miss the task functionality in Outlook 2010 for Windows.

  • Textmate Ruby on Rails Highlighting

    - by yuval
    Hi, I have textmate 1.5.7 running on my leopard machine. When programming in rails, for some reason some key words do not get highlighted. For example: validates_presence_of, has_many, remote_form_for (form_for gets highlighted) etc... I tried switching themes and it did not help. I also tried upgrading to the most recent rails bundle from http://railsbundle.com/ but no cigar. Could someone please help? Thank you very much, Yuval

  • VSS Post Backup failures for Virtual Server 2005 R2 SP1 virtual machines

    - by califguy4christ
    We've been seeing strange errors with Volume Shadow Copy services on our Virtual Server 2005 R2 SP1 host. It appears to be failing on a strange mountpoint in the C:\WINDOWS\Temp\ folders, which I believe is used by VSS to mount a writeable image file. To summarize: The Microsoft Virtual Server 2005 Writer continually goes into a failed retryable state The Virtual Server log reports errors during the Post Backup phase VSS reports errors backing up a mount point of unknown origins The mount point causes NTFS and ftdisk errors The host is x86 Windows Server 2003 Standard, SP2. The virtual machine is the same. Both use basic disks. Here is the writer state: Writer name: 'Microsoft Virtual Server 2005 Writer' Writer Id: {76afb926-87ad-4a20-a50f-cdc69412ddfc} Writer Instance Id: {78df98e2-bf19-4804-890b-15865efef3bd} State: [11] Failed Last error: Retryable error From the Virtual Server log: Virtual Server - Vss Writer - Event ID: 1035: The VSS writer for Virtual Server failed during the PostBackup phase. The guest shadow copies did not get exposed on the host machine, after mounting all the virtual hard disks of the virtual machine VMACHINE. From the Application log: VSS - None - Event ID: 12290: Volume Shadow Copy Service warning: GetVolumeInformationW( \\?\Volume{fb84bae7-87f5-11dd-9832-001cc4961ca6}\,NULL,0, NULL,NULL,[0x00000000], , 260) == 0x0000045d. hr = 0x00000000. From the System log: Ntfs - Disk - Event ID: 55: The file system structure on the disk is corrupt and unusable. Please run the chkdsk utility on the volume C:\WINDOWS\Temp\ {fb84bae7-87f5-11dd-9832-001cc49.... My current theory is that VSS creates a mount point for an image file of the VHD, then the software panics for some reason, leaving everything in an inconsistent state. Removing the mount point doesn't resolve the problem. All of the other disks check out fine with CHKDSK. There's no exclusion option for VHDs or to turn off online backups. Has anyone seen this kind of thing before or point me in the right direction for getting more information about the mount point and it's origins? I haven't been able to trace what application is creating that mount point.

  • Visual Web Developer, custom WHERE-clause for DataList, DataGrid

    - by m3n
    This question is not really related to programming but to using Visual Web Developer, but here goes: I'd like to use User.Identity.Name or any session variable in the WHERE-clause used by DataList (or other similar components), but I've tried the different options in the "ORDER BY..." pane to no avail. How do I stick that in there? Cheers

  • complete, monospaced Unicode font?

    - by nachik
    I'm looking for a good programming font that lets me add comments and string literals in Unicode, usually Japanese and Chinese along with some Latin and Cyrillic languages. So far the situation seems to be "complete, monospace, free, pick 2" and Google is failing me with this (maybe because there are no good ones?). The best I found is Arial Unicode but it's not monospace, which is a big nuisance for me and the editors I use. Not to mention Python indentation when I'm coding Python. (Links, edits are welcome)

  • setting up synergy (multi-computer shared input devices) new to mac

    - by pedalpete
    I've just gotten a mac and the first thing I'm trying to do in setting it up for dev is to set-up synergy. I've run into countless issues, and am making progress, but that 'mac's just work' theory is getting tired really fast. I'd prefer running the mac as the server, as it's a desktop. why use my pc(laptop) as the server. So i downloaded synergy, and tried to edit the 'synergy.conf' file. First with textmate, then with apple script. Neither of these applications will open the file. Even after changing textmate to use plain text format and switching off a few other things to make it into a plain text editor. No good. Uh, isn't that what these script/text editors are for? Then I found SyneryKM which is a package to run synergy on osx. Took LOTS of fiddling, but I think I finally kinda got it figured out. I've got my pc & mac both running synergy. However, my pc will only connect to synergy using the ip address. No problem, however, my mac won't connect to itself as a synergy server using the IP address. If I use the ip address as a screen in the 'server configuration file', i get a 'Error: unknown screen name mymac'. I know this shouldn't be super complicated, and possibly not the place to find answers about synergy, but I couldn't find a better place, and there has been some talk of synergy here. Any chance somebody can help with this?

  • Can URIs have non-ASCII characters?

    - by Cheeso
    I tried to find this in the relevant RFC, IETF RFC 3986, but couldn't figure it. Do URIs for HTTP allow Unicode, or non-ASCII of any kind? Can you please cite the section and the RFC that supports your answer. NB: For those who might think this is not programming related - it is. It's related to an ISAPI filter I'm building.
