  • Rails render partial with block

    - by brad
    I'm trying to re-use an html component that i've written that provides panel styling. Something like: <div class="v-panel"> <div class="v-panel-tr"></div> <h3>Some Title</h3> <div class="v-panel-c"> .. content goes here </div> <div class="v-panel-b"><div class="v-panel-br"></div><div class="v-panel-bl"></div></div> </div> So I see that render takes a block. I figured then I could do something like this: # /shared/_panel.html.erb <div class="v-panel"> <div class="v-panel-tr"></div> <h3><%= title %></h3> <div class="v-panel-c"> <%= yield %> </div> <div class="v-panel-b"><div class="v-panel-br"></div><div class="v-panel-bl"></div></div> </div> And I want to do something like: #some html view <%= render :partial => '/shared/panel', :locals =>{:title => "Some Title"} do %> <p>Here is some content to be rendered inside the panel</p> <% end %> Unfortunately this doesn't work with this error: ActionView::TemplateError (/Users/bradrobertson/Repos/VeloUltralite/source/trunk/app/views/sessions/new.html.erb:1: , unexpected tRPAREN old_output_buffer = output_buffer;;@output_buffer = ''; __in_erb_template=true ; @output_buffer.concat(( render :partial => '/shared/panel', :locals => {:title => "Welcome"} do ).to_s) on line #1 of app/views/sessions/new.html.erb: 1: <%= render :partial => '/shared/panel', :locals => {:title => "Welcome"} do -%> ... So it doesn't like the = obviously with a block, but if I remove it, then it just doesn't output anything. Does anyone know how to do what I'm trying to achieve here? I'd like to re-use this panel html in many places on my site.

  • link to a different libc file

    - by bobby
    I want to supply the shared libs along with my program rather than using the system's: ldd says my program uses these shared libs: linux-gate.so.1 = (0xf7ef0000)(made by kernel) libc.so.6 = /lib32/libc.so.6 (0xf7d88000)(libc-2.7.so) /lib/ld-linux.so.2 (0xf7ef1000)(ld-2.7.so) I have successfully linked ld-xxx.so by compiling like this: gcc -std=c99 -D_POSIX_C_SOURCE=200112L -O2 -m32 -s -Wl,-dynamic-linker,ld-2.7.so myprogram.c But I have not managed to successfuly link libc-xxx.so. How can I do that ?

  • Efficient copy of entire directory

    - by Hui Jin
    I want to copy one directory and the two files under it to another shared location of shared storage. Is it possible to combine the three(one directory and two files) as a continuous file writing and decompose it at another side to save the cost? I am limited to c language and Unix/Linux. I am considering to create a structure with the inode info and get the data at receiver. Thanks!

  • Serializing persistent/functional data structures

    - by Rob
    Persistent data structures depend on the sharing of structure for efficiency. For an example, see here. How can I preserve the structure sharing when I serialize the data structures and write them to a file or database? If I just naively traverse the datastructures, I'll store the correct values, but I'll lose the structure sharing. I'd like to be able to save data-structures with shared components to a file, restore them, and still have most of the structure shared in the restored data.

    I am writing installation script for my program, which is supposed to run on Linux/Unix OS. What is the default directory for the following files: Executable files (programs). Program should be executed by typing its name from the command line. Shared libraries. Third-party shared libraries (the program is not open source, so I need to redistribute third-party libraries). Read-only program configuration files for all users. Configuration data available for read/write access for all users.

  • TEMP_PART01 and C drive

    - by SmartLemon
    So we have a Samsung series 9 laptop and it has a 128 GB solid state drive, the problem we are having with it is that it has 4 partitions, one that's 100MB (who knows what for), one thats 40 GB (Primary Windows partition), 60 GB partition (TEMP_PART01) and a microsoft office one. The primary windows partition only has less than, 30 MB left, we want to increase this space, I know that I could just move everything to temp_part01 but we are not quite sure on it. What we are thinking of doing is deleting this partition all together and extending the windows volume. The problem is that the extra partition has 55.7 remaining out of 59.7 GB, which means there is something on it, but it shows up with nothing when we go into it, when we change the settings to show hidden files, but still nothing, I then used CMD to list all the files using dir d: and still no files. So would it be safe to delete it and extend the windows volume? Or what should I do? Here's a screen shot:

  • How can you use Windows Backup with a TrueCrypt encrypted backup destination?

    - by Burly
    Background There are numerous backup solutions out there for Windows and they come in many different forms. From a file copy and/or syncing tool like SyncBackSE to whole hard drive backup utilities based on Volume Shadow Copy like Acronis TrueImage or Norton Ghost to block level copy tools like dd. Each of these solutions offers different pros and cons versus the "Windows Backup and Restore Center" feature built-in to Windows Vista and Windows 7. I am not interested in discussing alternative backup solutions here however, as that has already been covered by numerous other questions. Contraints There are two "types" of backup supported by the "Windows Backup and Restore Center"(WBRC): - File backup (which Windows calls "Back Up Files") - Full System Backup (which Windows calls "Complete PC Backup) I am interested in a solution which supports either and/or both types of backup with WBRC. Questions How can you use a TrueCrypt encrypted mount point as the destination for the built-in "Windows Backup and Restore Center" feature in Windows Vista and 7? See-Also Volume Shadow Copy based backup that works with TrueCrypt References Backup and Restore Center Windows Vista - Backup and Restore Center Windows 7 - Backup and Restore Center

  • vgcreate --> "Command failed with status code 5." what does this mean?

    - by erik
    i'm playing around w/ LVM on a centos domU in a xen-based vps. I'm in rescue mode and I've created one physical volume (pvcreate /dev/xvda1) for my entire drive, which is formatted as LVM. i'm now trying to create a volume group using vgcreate main /dev/xvda1, but it's returning "Command failed with status code 5.". I've been unable to find an explanation for this error code. does anyone know what it means? for what it's worth, my goal is to create multiple logical volumes on my drive using lvm. thanks

  • VMFS recovery - how do you proceed?

    - by ToreTrygg
    The more I look into ESX the more often i have to handle cases where the partition table of a disk with a VMFS volume gets corrupted. The reasons for this can be * idiot user * failed update * power failure * .... I guess you guys must already have something like a usual procedure on how to work through this cases. I am especially interested in a straight fast way to find out if the VMFS volume itself is corrupted beyond repair. So far I use very time consuming attempts with scans with Testdisk and similar tools. Do you have better / faster ways ?

  • Can an installation of SSRS be used for other reports if the SCOM Reporting Role is installed?

    - by Pete Davis
    I'm currently in the process of planing a SCOM 2007 R2 deployment and would like to deploy the OperationsManagerDW and Reporting Server to a shared SQL 2008 cluster which is used for reporting across multiple solutions. However in the in the deployment guide for SCOM 2007 R2 it says: Due to changes that the Operations Manager 2007 Reporting component makes to SQL Server Reporting Services security, no other applications that make use of SQL Server Reporting Services can be installed on this server. Which concerns me that it may interfere with existing or future (non SCOM) reports in some way even if deployed as a separate SSRS instance. Later in the same guide it states: Installing Operations Manager 2007 Reporting Services integrates the security of the instance of SQL Reporting Services with the Operations Manager role-based security. Do not install any other Reporting Services applications in this same instance of SQL Server. Does this mean that I can install a new SSRS instance and use this on the shared cluster for SCOM reporting or that I'd also need to create a whole new SQL Server instance as well as SSRS instance or I'd need a whole separate server for SCOM OperationsManagerDW and Reporitng Server?

  • Parallel prologue and epilogue in Grid Engine

    - by ajdecon
    We have a cluster being used to run MPI jobs for a customer. Previously this cluster used Torque as the scheduler, but we are transitioning to Grid Engine 6.2u5 (for some other features). Unfortunately, we are having trouble duplicating some of our maintenance scripts in the Grid Engine environment. In Torque, we have a prologue.parallel script which is used to carry out an automated health-check on the node. If this script returns a fail condition, Torque will helpfully offline the node and re-queue the job to use a different group of nodes. In Grid Engine, however, the queue "prolog" only runs on the head node of the job. We can manually run our prologue script from the startmpi.sh initialization script, for the mpi parallel environment; but I can't figure out how to detect a fail condition and carry out the same "mark offline and requeue" procedure. Any suggestions?

  • Disk performance below expectations

    - by paulH
    this is a follow-up to a previous question that I asked (Two servers with inconsistent disk speed). I have a PowerEdge R510 server with a PERC H700 integrated RAID controller (call this Server B) that was built using eight disks with 3Gb/s bandwidth that I was comparing with an almost identical server (call this Server A) that was built using four disks with 6Gb/s bandwidth. Server A had much better I/O rates than Server B. Once I discovered the difference with the disks, I had Server A rebuilt with faster 6Gbps disks. Unfortunately this resulted in no increase in the performance of the disks. Expecting that there must be some other configuration difference between the servers, we took the 6Gbps disks out of Server A and put them in Server B. This also resulted in no increase in the performance of the disks. We now have two identical servers built, with the exception that one is built with six 6Gbps disks and the other with eight 3Gbps disks, and the I/O rates of the disks is pretty much identical. This suggests that there is some bottleneck other than the disks, but I cannot understand how Server B originally had better I/O that has subsequently been 'lost'. Comparative I/O information below, as measured by SQLIO. The same parameters were used for each test. It's not the actual numbers that are significant but rather the variations between systems. In each case D: is a 2 disk RAID 1 volume, and E: is a 4 disk RAID 10 volume (apart from the original Server A, where E: was a 2 disk RAID 0 volume). Server A (original setup with 6Gpbs disks) D: Read (MB/s) 63 MB/s D: Write (MB/s) 170 MB/s E: Read (MB/s) 68 MB/s E: Write (MB/s) 320 MB/s Server B (original setup with 3Gpbs disks) D: Read (MB/s) 52 MB/s D: Write (MB/s) 88 MB/s E: Read (MB/s) 112 MB/s E: Write (MB/s) 130 MB/s Server A (new setup with 3Gpbs disks) D: Read (MB/s) 55 MB/s D: Write (MB/s) 85 MB/s E: Read (MB/s) 67 MB/s E: Write (MB/s) 180 MB/s Server B (new setup with 6Gpbs disks) D: Read (MB/s) 61 MB/s D: Write (MB/s) 95 MB/s E: Read (MB/s) 69 MB/s E: Write (MB/s) 180 MB/s Can anybody suggest any ideas what is going on here? The drives in use are as follows: Dell Seagate F617N ST3300657SS 300GB 15K RPM SAS Dell Hitachi HUS156030VLS600 300GB 3.5 inch 15000rpm 6GB SAS Hitachi Hus153030vls300 300GB Server SAS Dell ST3146855SS Seagate 3.5 inch 146GB 15K SAS
