• High mysql server load, sar output

  - by eric

  I have a MySQL Server that should be performing better than it seems to be. We're running ubuntu on a Amazon Cluster Compute (cc1.4xlarge) Linux ip-10-0-1-60 3.2.0-25-virtual #40-Ubuntu SMP Wed May 23 22:20:17 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux Distributor ID: Ubuntu Description: Ubuntu 12.04 LTS Release: 12.04 Codename: precise I have several output files from sar that i'm not really sure how to interpret. For example, I ran: # Individual block device I/O activities sar -d 1 180 > logs/block_device_io.log & which gave me what looks like really high utilisation of my disk (turns out this block device maps to /dev/xvdh on /var/lib/mysql type ext4 (rw,_netdev) The output from my log: 10:48:59 PM DEV tps rd_sec/s wr_sec/s avgrq-sz avgqu-sz await svctm %util 10:49:00 PM dev202-16 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 10:49:00 PM dev202-32 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 10:49:00 PM dev8-0 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 10:49:00 PM dev202-112 1008.00 31040.00 1416.00 32.20 1.02 1.01 0.89 90.00 10:49:00 PM dev202-80 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 Am I wrong in thinking this is a problem?

• Alternative Input Device(Midi) doesn't prevent Screen Saver in Winforms application

  - by DTig

  I have developed a c# winforms application whereby the user is providing input via a midi connected device. The user will go for long periods without using the keyboard or mouse. When I receive a midi message is there anything I can do to "tell" the system that this counts as user activity (ie key press). I don't want the screen saver or time lockouts to occur, if they are actively using the midi device. I think my request is different than other requests I've seen because they want to disable screen savers for the life of their application whereby I just want midi input I receive to count as user interactivity. Is there something I can call when I receive midi input to signify to the system user activity?

• Python's subprocess.Popen object hangs gathering child output when child process does not exit

  - by Daniel Miles

  When a process exits abnormally or not at all, I still want to be able to gather what output it may have generated up until that point. The obvious solution to this example code is to kill the child process with an os.kill, but in my real code, the child is hung waiting for NFS and does not respond to a SIGKILL. #!/usr/bin/python import subprocess import os import time import signal import sys child_script = """ #!/bin/bash i=0 while [ 1 ]; do echo "output line $i" i=$(expr $i \+ 1) sleep 1 done """ childFile = open("/tmp/childProc.sh", 'w') childFile.write(child_script) childFile.close() cmd = ["bash", "/tmp/childProc.sh"] finish = time.time() + 3 p = subprocess.Popen(cmd, stdout=subprocess.PIPE, stderr=subprocess.PIPE, stdin=subprocess.PIPE) while p.poll() is None: time.sleep(0.05) if finish < time.time(): print "timed out and killed child, collecting what output exists so far" out, err = p.communicate() print "got it" sys.exit(0) In this case, the print statement about timing out appears and the python script never exits or progresses. Does anybody know how I can do this differently and still get output from my child processe

• NUnit does not capture output of std::cerr

  - by Richard

  I have an nunit Test in C#, that calls a C# wrapper of a function in a C++ DLL. The C++ code uses std::cerr to output various messages. These messages cannot be redirected using nunit-console /out /err or /xml switch. In nunit (the GUI version) the output does not appear anywhere. I would like to be able to see this output in nunit (GUI version). Ideally I would like to be able to access this output in the Test. Thanks for any help.

• Install multiple iPhone apps at once from Xcode to device

  - by Dimitris

  Supposing we have an Xcode iPhone project with 2 targets, is it possible to build and install both of them on the device with one click? Of course, I understand we will not be able to "build and run" both, but can we at least install them? And to extend this concept a bit a bit: are there any scripts to achieve the same thing but with multiple iPhone projects instead of multiple targets in one project? This would be useful when you want to load all your apps on a new development device and don't want to go through all your projects one by one and install.

• Microsecond (or one ms) time resolution on an embedded device (Linux Kernel)

  - by ChrisDiRulli

  Hey guys, I have a kernel module I've built that requires at least 1 ms time resolution. I currently use do_gettimeofday() but I'm concerned that this won't work once I move my module to an embedded device. The device has a 180 Mz processor (MIPS) and the default HZ value in the kernel is 100. Thus using jiffies will only give me at best 10 ms resolution. That won't cut it. What I'd like to know is if do_gettimeofday() is based on the timer interrupt (HZ). Can it be guaranteed to provide at least 1 ms of resolution? Thanks!

• Make VS 2008 Auto Deploy SQL Server CE 3.5 When Debugging on Windows Mobile 5.0 Device

  - by INTPnerd

  How do you make VS 2008 automatically install SQL Server CE 3.5 when debugging (F5) a CF app on a windows Mobile 5.0 device? VS used to do this automatically, but now it stopped and I don't know why. I have changed the structure of my solution and the projects, but it is still using SQL Server CE 3.5. It used to also install the Query Analyzer as well which was useful. I frequently uninstall all the programs on the device or do hard reboots so installing this manually is what I am trying to avoid.

• How to output formatted HTML from PHP?

  - by Tim

  I like to format all my HTML with tabs for neatness and readability. Recently I started using PHP and now I have a lot of HTML output that comes from in between PHP tags. Those output lines all line up one the left side of the screen. I have to use /n to make a line go to the next. Is there anything like that for forcing tabs, or any way to have neat HTML output coming from PHP?

• Finding out whether a DirectInput device supports XInput (with mingw/gcc)

  - by Mr. Wonko

  I'm working on an input system, wrapping DirectInput and XInput. Currently XInput devices are enumerated twice, once as XInput and once as DirectInput (since they support both). How can I find out if a given DirectInput device also supports XInput? There is this MSDN page on the topic, but it requires wbemidl.h and wmsstd.h which aren't available in mingw/gcc (and for some reason I want to avoid msvc - probably by habit). I don't think blacklisting device names/guids is a good solution, but is there a better one? Thanks.

• Problems referencing build output from TFS Build and Visual Studio

  - by pmdarrow

  Here's what I'm trying to do: I have two solutions - one for my main application and its associated projects and another for my database (VS .dbproj) and its associated projects. What I'd like to do is include the output from the database project (a .dbschema and some SQL scripts) in my WiX installer (which exists in the main application solution.) This involves having TFS build the DB solution immediately before the main application solution. I've got that part working properly, but I'm having trouble referencing the output of the DB solution from my installer. I'm using relative paths to reference the DB project output in my WiX installer (e.g. <?define DBProjectOutputDir = "..\..\MyDatabaseSolution\MyDatabaseProject\sql\"?>) which works fine locally, but fails when building via TFS build. This is because TFS Build apparently changes the output dir of each project to one common location. Instead of the path to my database project being ..\..\MyDatabaseSolution\MyDatabaseProject\sql\ like it is when building locally, it gets set to something like ..\..\..\Binaries\Release\. How can I get around this and have a consistent output location to reference from my installer project? I'm using TFS 2005 and VS 2008.

• Capture and display console output at the same time

  - by Patrick

  Hi, MSDN states that it is possible in .NET to capture the output of a process and display it in the console window at the same time. Normally when you set StartInfo.RedirectStandardOutput = true; the console window stays blank. As the MSDN site doesn't provide a sample for this I was wondering if anyone would have a sample or could point me to a sample? When a Process writes text to its standard stream, that text is normally displayed on the console. By redirecting the StandardOutput stream, you can manipulate or suppress the output of a process. For example, you can filter the text, format it differently, or write the output to both the console and a designated log file. MSDN This post is similar to http://stackoverflow.com/questions/786726/capture-standard-output-and-still-display-it-in-the-console-window by the way. But that post didn't end up with a working sample. Thanks a lot, Patrick

• Consuming a USB HID device in Windows CE 6.0 using c#

  - by kersny

  I am working on an Embedded Windows CE project and am interested in accessing a USB HID device through one of its USB Host ports. All I really need to read are the raw HID spec packets. On a windows computer, I have a working program using hid.dll, but as far as I have researched, there is no equivalent on CE. I know there is the usbhid.dll, but I'm not sure if it is applicable for this situation. I would prefer not to write a kernel level driver, as I would like to do my coding in c#. Has anyone had experience consuming an HID device on Windows CE?

• How to register a function in a driver code as its ISR

  - by CVS-2600Hertz-wordpress-com

  Following the feedback i got from: http://stackoverflow.com/questions/2683682/new-to-linux-kernel-driver-development/2683819 I have written a driver (.c file) by comparing it with an existing driver and "borrowing" heavily from its code. The driver is registered fine and init() and probe() are working fine. I am also able to access the peripheral device registers. :-) However i am a bit hazy about the IRQ/ISR. The peripheral-device is a input device and raises an interrupt on a GPIO pin. How do i move ahead from my current state ( init(), probe(), etc. ) to be able to handle the IRQ and execute my ISR function?? Many-Thanks in Advance

• When to best implement a I2C driver module in Linux

  - by stefangachter

  I am currently dealing with two devices connected to the I2C bus within an embedded system running Linux. I am using an exisiting driver for the first device, a camera. For the second device, I have successfully implemented a userspace program with which I can communicate with the second device. So far, both devices seem to coexist happily. However, almost all I2C devices have their own driver module. Thus, I am wondering what the advantages of a driver module are. I had a look at the following thread... http://stackoverflow.com/questions/149032/when-should-i-write-a-linux-kernel-module ... but without conclusion. Thus, what would be the advantage of writing a I2C driver module over a userspace implementation? Regards, Stefan

• get height on a block of latex output

  - by georg raba

  Hello, I am trying to determine how to get the height on a block of latex output (not the whole document, and not the code..but rather a block of output). As an example of what I am trying to accomplish: i were to have the latex code $\sum_{i=0}^\infty \frac{1}{n}\infty$ \newline hello world \newline hello universe its output would be something like 2 inches high. Of course, the height of the above block of text is dependent on a number of things-font, margin size, etc, as changing any of these parameters changes how many inches that output would be. Is there a command/package that does this? Thanks in advance! Georg Raba

• Double value not correct on Device

  int min = Int32.Parse(minutebox.Text); double kj = Convert.ToDouble(a.kj); double res = ((kj * op.koerpergewicht) * min); textbox.Text = res.ToString(); Shows me the correct number (with its punctuation - i. e. 2.33) on my English WP7-Emulator. However it doesn't work on my Device, which is set to German. The value is correct but the point, comma or whatever in that double value isn't shown correct. 43.22 on Emulator - 4322 on Device Why is that?
