  • Shell command slow when using pipe, fast with intermediate file

    - by plang
    Does anyone understand this huge difference in processing time, when using an intermediate file, or when using a pipe? I'm converting tiff to pdf using standard tools on a fresh debian squeeze server. A standard way of doing this is to convert to ps first. Without pipe: root@web5:~# time tiff2ps test.tif > test.ps real 0m0.860s user 0m0.744s sys 0m0.112s root@web5:~# time ps2pdf13 -sPAPERSIZE=a4 test.ps > test.pdf real 0m0.667s user 0m0.612s sys 0m0.060s With pipe: root@web5:~# time tiff2ps test.tif | ps2pdf13 -sPAPERSIZE=a4 - > test.pdf real 1m6.098s user 0m15.861s sys 0m50.9 During the last command, gs process is at 100% all the time. Update: Here is an strace output for the ps generation: root@web5:~# strace tiff2ps test.tif > test.ps execve("/usr/bin/tiff2ps", ["tiff2ps", "test.tif"], [/* 28 vars */]) = 0 brk(0) = 0x1395000

  • Office 2013 OCT unhandled exception when saving .RSP

    - by user52874
    I'm trying to prepare a deployment of office 2013 pro plus. If I deploy an existing .rsp file that was left behind by the old analyst (typing from the client): PS C: \\deploybox\software\Office2013\setup.exe /adminfile \\deploybox\software\Office2013\SWKS.MSP Things seem to deploy just fine. if I make any changes to the .rsp file by doing (all from the client): PS C: \\deploybox\software\Office2013\setup.exe /admin * Open SWKS.MSP * Make changes * Save under a different name SWKS1.MSP I get the following errorbox: Unhandled Exception: MsiGetSummaryInformation call failed. And if I try to deploy the new SWKS1.MSP, PS C: \\deploybox\software\Office2013\setup.exe /adminfile \\deploybox\software\Office2013\SWKS1.MSP it fails with the message: Path or file specified with /adminfile did not contain any customization patches that apply to this product or platform. If I even open the old known good .rsp file SWKS.MSP, and immediately save it as a new name SWKS1.MSP, making no changes, then the same thing happens. So what stupid newbie mistake am I making here? Thanks!

  • Trouble using Upstart to launch Redis as redis user

    - by Chris
    I'm trying to launch redis-server as a user (called redis) via Upstart. My /etc/init/redis-server.conf looks like this: description "redis server" start on runlevel [23] stop on shutdown exec sudo -u redis /usr/local/bin/redis-server /var/lib/redis/redis.conf Looks good, right? I start redis-server using $start redis-server redis-server start/running, process 16808 $redis-cli Could not connect to Redis at 127.0.0.1:6379: Connection refused $ps ax | grep ps 168 16810 tty1 R+ 0:00 ps ax 16811 tty1 S+ 0:00 grep 168 So redis-server definitely isn't running. Let's try executing the Upstart command by hand, shall we? exec sudo -u redis /usr/local/bin/redis-server /var/lib/redis/redis.conf [16852] 19 Jun 10:37:21 # Can't chdir to './': Permission denied Connection to 10.19.2.94 closed. And then I get logged off. I'm at a loss. Any ideas?

    I am searching for a way to type a keyword in the start menu Search programs and files field and that it will return the application that match the keyword. An example will better explain this: Suppose that I want to start the powershell. Currently what I can type in the search field is power and the first item that appear is the 64bits powershell shortcut. Now suppose that I'd like ps to return powershell as the first item of the search list. Currently, typing ps return all files with the .ps extension, alongs with a control panel options about recording steps but not the powershell executable itself. How can I do that?

  • Finding source of leaking active memory on Mac OS Lion

    - by Tim Kemp
    My activity monitor shows 6GB of active RAM usage: Yet my Real Memory column shows nothing like that amount: (There's another screenful below that, all smaller.) Backing that up, the output from this command (which sums up memory usage of every running process): ps -axm -o "rss,comm" | awk 'BEGIN { s=0;}; {s=s+$1;}; END { printf("%.2f GB\n", (s/1024.0/1024));}' Gives 4.09GB, so it looks to me like 2GB has leaked. I see much wider ranges sometimes, perhaps 2 or 3GB from the ps command and as much as 7 or 8GB of Active usage reported by Activity Monitor. I've tried quitting everything and logging my user out and back in again, but the Active usage is still far higher than the RAM reported by ps and by each process to Activity Monitor. This 2GB of active RAM is basically unrecoverable unless I reboot. Is there any way to a) detect what's leaking and b) get it back? Thanks

  • powershell Read-host does not stop for input

    - by llirik42
    I thought this would be fairly basic, but i'm stuck. I have 3 lines of powershell script in which I want to collect a mailbox name from user input, then create names based on that mailbox name. (later the script proceeds to create the groups in AD, etc) my problem is that when I run all 3 of these lines by pasting them into powershell window, I don't get a change to enter the response to read-host. Instead the script just scrolls through to the next line and uses it as the response for the Read-Host here's the powershell: $name = read-host "enter group name" $groupfull = ($name+'.Full'a) $groupsendas = ($name+'.SendAs') Here's the output: PS C:\Users\kg> $name = read-host "enter group name" enter group name: $groupfull = ($name+'.Full') PS C:\Users\kg> $groupsendas = ($name+'.SendAs') PS C:\Users\kg> Thanks in advance

  • Halloween: Season for Java Embedded Internet of Spooky Things (IoST) (Part 2)

    - by hinkmond
    To start out our ghost hunting here at the Oracle Santa Clara campus office, we first need a ghost sensor. It's pretty easy to build one, since all we need to do is to create a circuit that can detect small fluctuations in the electromagnetic field, just like the fluctuations that ghosts cause when they pass by... Naturally, right? So, we build a static charge sensor and will use a Java Embedded app to monitor for changes in the sensor value, running analytics using Java technology on a Raspberry Pi. Bob's your uncle, and there you have it: a ghost sensor. See: Ghost Detector So, go out to Radio Shack and buy up these items: shopping list: 1 - NTE312 JFET N-channel transistor (this is in place of the MPF-102) 1 - Set of Jumper Wires 1 - LED 1 - 300 ohm resistor 1 - set of header pins Then, grab a flashlight, your Raspberry Pi, and come back here for more instructions... Don't be afraid... Yet. Hinkmond

  • Copy vector of values to vector of pairs in one line

    - by Kirill V. Lyadvinsky
    I have the following types: struct X { int x; X( int val ) : x(val) {} }; struct X2 { int x2; X2() : x2() {} }; typedef std::pair<X, X2> pair_t; typedef std::vector<pair_t> pairs_vec_t; typedef std::vector<X> X_vec_t; I need to initialize instance of pairs_vec_t with values from X_vec_t. I use the following code and it works as expected: int main() { pairs_vec_t ps; X_vec_t xs; // this is not empty in the production code ps.reserve( xs.size() ); { // I want to change this block to one line code. struct get_pair { pair_t operator()( const X& value ) { return std::make_pair( value, X2() ); } }; std::transform( xs.begin(), xs.end(), back_inserter(ps), get_pair() ); } return 0; } What I'm trying to do is to reduce my copying block to one line with using boost::bind. This code is not working: for_each( xs.begin(), xs.end(), boost::bind( &pairs_vec_t::push_back, ps, boost::bind( &std::make_pair, _1, X2() ) ) ); I know why it is not working, but I want to know how to make it working without declaring extra functions and structs?

  • UppercuT &ndash; Custom Extensions Now With PowerShell and Ruby

    - by Robz / Fervent Coder
    Arguably, one of the most powerful features of UppercuT (UC) is the ability to extend any step of the build process with a pre, post, or replace hook. This customization is done in a separate location from the build so you can upgrade without wondering if you broke the build. There is a hook before each step of the build has run. There is a hook after. And back to power again, there is a replacement hook. If you don’t like what the step is doing and/or you want to replace it’s entire functionality, you just drop a custom replacement extension and UppercuT will perform the custom step instead. Up until recently all custom hooks had to be written in NAnt. Now they are a little sweeter because you no longer need to use NAnt to extend UC if you don’t want to. You can use PowerShell. Or Ruby.   Let that sink in for a moment. You don’t have to even need to interact with NAnt at all now. Extension Points On the wiki, all of the extension points are shown. The basic idea is that you would put whatever customization you are doing in a separate folder named build.custom. Each step Let’s take a look at all we can customize: The start point is default.build. It calls build.custom/default.pre.build if it exists, then it runs build/default.build (normal tasks) OR build.custom/default.replace.build if it exists, and finally build.custom/default.post.build if it exists. Every step below runs with the same extension points but changes on the file name it is looking for. NOTE: If you include default.replace.build, nothing else will run because everything is called from default.build.    * policyChecks.step    * versionBuilder.step NOTE: If you include build.custom/versionBuilder.replace.step, the items below will not run.      - svn.step, tfs.step, or git.step (the custom tasks for these need to go in build.custom/versioners)    * generateBuildInfo.step    * compile.step    * environmentBuilder.step    * analyze.step NOTE: If you include build.custom/analyze.replace.step, the items below will not run.      - test.step (the custom tasks for this need to go in build.custom/analyzers) NOTE: If you include build.custom/analyzers/test.replace.step, the items below will not run.        + mbunit2.step, gallio.step, or nunit.step (the custom tasks for these need to go in build.custom/analyzers)      - ncover.step (the custom tasks for this need to go in build.custom/analyzers)      - ndepend.step (the custom tasks for this need to go in build.custom/analyzers)      - moma.step (the custom tasks for this need to go in build.custom/analyzers)    * package.step NOTE: If you include build.custom/package.replace.step, the items below will not run.      - deploymentBuilder.step Customize UppercuT Builds With PowerShell UppercuT can now be extended with PowerShell (PS). To customize any extension point with PS, just add .ps1 to the end of the file name and write your custom tasks in PowerShell. If you are not signing your scripts you will need to change a setting in the UppercuT.config file. This does impose a security risk, because this allows PS to now run any PS script. This setting stays that way on ANY machine that runs the build until manually changed by someone. I’m not responsible if you mess up your machine or anyone else’s by doing this. You’ve been warned. Now that you are fully aware of any security holes you may open and are okay with that, let’s move on. Let’s create a file called default.replace.build.ps1 in the build.custom folder. Open that file in notepad and let’s add this to it: write-host "hello - I'm a custom task written in Powershell!" Now, let’s run build.bat. You could get some PSake action going here. I won’t dive into that in this post though. Customize UppercuT Builds With Ruby If you want to customize any extension point with Ruby, just add .rb to the end of the file name and write your custom tasks in Ruby.  Let’s write a custom ruby task for UC. If you were thinking it would be the same as the one we just wrote for PS, you’d be right! In the build.custom folder, lets create a file called default.replace.build.rb. Open that file in notepad and let’s put this in there: puts "I'm a custom ruby task!" Now, let’s run build.bat again. That’s chunky bacon. UppercuT and Albacore.NET Just for fun, I wanted to see if I could replace the compile.step with a Rake task. Not just any rake task, Albacore’s msbuild task. Albacore is a suite of rake tasks brought about by Derick Bailey to make building .NET with Rake easier. It has quite a bit of support with developers that are using Rake to build code. In my build.custom folder, I drop a compile.replace.step.rb. I also put in a separate file that will contain my Albacore rake task and I call that compile.rb. What are the contents of compile.replace.step.rb? rake = 'rake' arguments= '-f ' + Dir.pwd + '/../build.custom/compile.rb' #puts "Calling #{rake} " + arguments system("#{rake} " + arguments) Since the custom extensions call ruby, we have to shell back out and call rake. That’s what we are doing here. We also realize that ruby is called from the build folder, so we need to back out and dive into the build.custom folder to find the file that is technically next to us. What are the contents of compile.rb? require 'rubygems' require 'fileutils' require 'albacore' task :default => [:compile] puts "Using Ruby to compile UppercuT with Albacore Tasks" desc 'Compile the source' msbuild :compile do |msb| msb.properties = { :configuration => :Release, :outputpath => '../../build_output/UppercuT' } msb.targets [:clean, :build] msb.verbosity = "quiet" msb.path_to_command = 'c:/Windows/Microsoft.NET/Framework/v3.5/MSBuild.exe' msb.solution = '../uppercut.sln' end We are using the msbuild task here. We change the output path to the build_output/UppercuT folder. The output path has “../../” because this is based on every project. We could grab the current directory and then point the task specifically to a folder if we have projects that are at different levels. We want the verbosity to be quiet so we set that as well. So what kind of output do you get for this? Let’s run build.bat custom_tasks_replace:      [echo] Running custom tasks instead of normal tasks if C:\code\uppercut\build\..\build.custom\compile.replace.step exists.      [exec] (in C:/code/uppercut/build)      [exec] Using Ruby to compile UppercuT with Albacore Tasks      [exec] Microsoft (R) Build Engine Version 3.5.30729.4926      [exec] [Microsoft .NET Framework, Version 2.0.50727.4927]      [exec] Copyright (C) Microsoft Corporation 2007. All rights reserved. If you think this is awesome, you’d be right!   With this knowledge you shall build.

  • Windows PowerShell ISE doesn't import PSCX 2.0 module

    Hi, i am using Powershell 2.0 with the PSCX 2.0 module. When writing PS scripts inside Windows PowerShell ISE no Cmdlets from the PSCX module are availible. For example running "Get-DriveInfo" from Windows PowerShell ISE would cause an error. Running "Get-DriveInfo" from Powershell works fine. I guess Windows PowerShell ISE doesn't load my PS profile (this would be mad). Does anyone know why and what to do to get it work?

  • How to get physical partition name from iSCSI details on Windows?

    - by Barry Kelly
    I've got a piece of software that needs the name of a partition in \Device\Harddisk2\Partition1 style, as shown e.g. in WinObj. I want to get this partition name from details of the iSCSI connection that underlies the partition. The trouble is that disk order is not fixed - depending on what devices are connected and initialized in what order, it can move around. So suppose I have the portal name (DNS of the iSCSI target), target IQN, etc. I'd like to somehow discover which volumes in the system relate to it, in an automated fashion. I can write some PowerShell WMI queries that get somewhat close to the desired info: PS> get-wmiobject -class Win32_DiskPartition NumberOfBlocks : 204800 BootPartition : True Name : Disk #0, Partition #0 PrimaryPartition : True Size : 104857600 Index : 0 ... From the Name here, I think I can fabricate the corresponding name by adding 1 to the partition number: \Device\Harddisk0\Partition1 - Partition0 appears to be a fake partition mapping to the whole disk. But the above doesn't have enough information to map to the underlying physical device, unless I take a guess based on exact size matching. I can get some info on SCSI devices, but it's not helpful in joining things up (iSCSI target is Nexenta/Solaris COMSTAR): PS> get-wmiobject -class Win32_SCSIControllerDevice __GENUS : 2 __CLASS : Win32_SCSIControllerDevice ... Antecedent : \\COBRA\root\cimv2:Win32_SCSIController.DeviceID="ROOT\\ISCSIPRT\\0000" Dependent : \\COBRA\root\cimv2:Win32_PnPEntity.DeviceID="SCSI\\DISK&VEN_NEXENTA&PROD_COMSTAR... Similarly, I can run queries like these: PS> get-wmiobject -namespace ROOT\WMI -class MSiSCSIInitiator_TargetClass PS> get-wmiobject -namespace ROOT\WMI -class MSiSCSIInitiator_PersistentDevices These guys return information relating to my iSCSI target name and the GUID volume name respectively (a volume name like \\?\Volume{guid-goes-here}), but the GUID volume name is no good to me, and there doesn't appear to be a reliable correspondence between the target name and the volume that I can join on. I simply can't find an easy way of getting from an IQN (e.g. iqn.1992-01.com.example:storage:diskarrays-sn-a8675309) to physical partitions mapped from that target. The way I do it by hand? I start Disk Management, and look for a partition of the correct size, verify that its driver says NEXENTA COMSTAR, and look at the disk number. But even this is unreliable if I have multiple iSCSI volumes of the exact same size. Any suggestions?

  • How to poll the username, when having the UID?

    - by JMW
    we're using ldap with sssd for the usermanagement, so our users are not in the "/etc/passwd" Unfortunately, ps just shows the UIDs: [root@xyz ~]# id jmw uid=1582(jmw) gid=1582(jmw) groups=1582(jmw), 1000(admins) [root@xyz ~]# ps aux [..cutting some output..] 1582 26794 25.0 0.4 190420 38508 ? S 12:15 0:00 /usr/bin/php-cgi -c php.ini [..cutting some output..] How can i poll the username, that belongs to a UID? ( a grep ':1582:' /etc/passwd doesn't work ;-) )
