  • Merging and sorting multiple files with "sort"

    - by NewbiZ
    Hello, I have a bunch of text logfiles in the following format: ID (17 characters) Timestamp (14 characters YYYYmmddHHMMSS e.g. "20060210100040" -> 2006/02/10 10:00:40) Random data (? characters) end of line The files are already sorted by timestamp. I need to get 1 log file with all the logs from multiple logs files, sorted by timestamp. Note that the log files are really huge, around 3-4G each (and there are dozens of them) I tried the following command: sort -s -m -t '|' -k1n,1n +17 -o data_sort.txt *.TXT Here is how I ended up with this command: -s : don't bother with tie results -m : merge all logs files -t '|' : there is no | in my logs, so the whole line should be field 1 -k1n,1n: sort on the first field as a numeric value +17 : the timestamp starts at index 17 -o : output file Actually... it fails miserably. The output file data_sort.txt is just the concatenation of all files, not sorted at all :( I would greatly appreciate if anyone could provide any help on this problem! Thanks

  • Key Promoter for NetBeans

    - by Geertjan
    Whenever a menu item or toolbar button is clicked, it would be handy if NetBeans were to tell you 'hey, did you know, you can actually do this via the following keyboard shortcut', if a keyboard shortcut exists for the invoked action. After all, ultimately, a lot of developers would like to do everything with the keyboard and a key promoter feature of this kind is a helpful tool in learning the keyboard shortcuts related to the menu items and toolbar buttons you're clicking with your mouse. Above, you see the balloon message that appears for each menu item and toolbar button that you click and, below, you can see a list of all the actions that have been logged in the Notifications window. That happens automatically when an action is invoked (assuming the plugin described in this blog entry is installed), showing the display name of the action, together with the keyboard shortcut, which is presented as a hyperlink which, when clicked, re-invokes the action (which might not always be relevant, especially for context-sensitive actions, though for others it is quite useful, e.g., reopen the New Project wizard). And here's all the code. Notice that I'm hooking into the 'uigestures' functionality, which was suggested by Tim Boudreau, and I have added my own handler, which was suggested by Jaroslav Tulach, which gets a specific parameter from each new log entry handled by the 'org.netbeans.ui.actions' logger, makes sure that the parameter actually is an action, and then gets the relevant info from the action, if the relevant info exists: @OnShowingpublic class Startable implements Runnable {    @Override    public void run() {        Logger logger = Logger.getLogger("org.netbeans.ui.actions");        logger.addHandler(new StreamHandler() {            @Override            public void publish(LogRecord record) {                Object[] parameters = record.getParameters();                if (parameters[2] instanceof Action) {                    Action a = (Action) parameters[2];                    JMenuItem menu = new JMenuItem();                    Mnemonics.setLocalizedText(                            menu,                             a.getValue(Action.NAME).toString());                    String name = menu.getText();                    if (a.getValue(Action.ACCELERATOR_KEY) != null) {                        String accelerator = a.getValue(Action.ACCELERATOR_KEY).toString();                        NotificationDisplayer.getDefault().notify(                                name,                                 new ImageIcon("/org/nb/kp/car.png"),                                 accelerator,                                 new ActionListener() {                            @Override                            public void actionPerformed(ActionEvent e) {                                a.actionPerformed(e);                            }                        });                    }                }            }        });    }} Indeed, inspired by the Key Promoter in IntelliJ IDEA. Interested in trying it out? If there's interest in it, I'll put it in the NetBeans Plugin Portal.

  • Brief material on C++ object-lifetime management and on passing and returning values/references

    - by dsign
    I was wondering if anybody can point to a post, pdf, or excerpt of a book containing the rules for C++ variable life-times and best practices for passing and returning function parameters. Things like when to pass by value and by reference, how to share ownership, avoid unnecessary copies, etc. This is not for a particular problem of mine, I've been programming in C++ for long enough to know the rules by instinct, but it is something that a lot of newcomers to the language stumble with, and I would be glad to point them to such a thing.

  • Calculating distance from viewer to object in a shader

    - by Jay
    Good morning, I'm working through creating the spherical billboards technique outlined in this paper. I'm trying to create a shader that calculates the distance from the camera to all objects in the scene and stores the results in a texture. I keep getting either a completely black or white texture. Here are my questions: I assume the position that's automatically sent to the vertex shader from ogre is in object space? The gpu interpolates the output position from the vertex shader when it sends it to the fragment shader. Does it do the same for my depth calculation or do I need to move that calculation to the fragment shader? Is there a way to debug shaders? I have no errors but I'm not sure I'm getting my parameters passed into the shaders correctly. Here's my shader code: void DepthVertexShader( float4 position : POSITION, uniform float4x4 worldViewProjMatrix, uniform float3 eyePosition, out float4 outPosition : POSITION, out float Depth ) { // position is in object space // outPosition is in camera space outPosition = mul( worldViewProjMatrix, position ); // calculate distance from camera to vertex Depth = length( eyePosition - position ); } void DepthFragmentShader( float Depth : TEXCOORD0, uniform float fNear, uniform float fFar, out float4 outColor : COLOR ) { // clamp output using clip planes float fColor = 1.0 - smoothstep( fNear, fFar, Depth ); outColor = float4( fColor, fColor, fColor, 1.0 ); } fNear is the near clip plane for the scene fFar is the far clip plane for the scene

  • grep with after-context that does not contain a keyword

    - by ukasz
    I want to grep through logs, and gather a certain exception stacktrace but I want to only see those that do not contain certain keywords in --after-context. I do not know in which line in after-context the keyword is. Simple example - given this shell code: grep -A 2 A <<EOF A B C R A Z Z X EOF the output is: A B C -- A Z Z I'd like the output to be: A Z Z I want to exclude any match that has 'B' in after-context How do I do this? Using grep is not a requirement, though I only have access to coreutils and perl.

  • Virtualbox install 12.04 guest: "pae not present"

    - by Peter.O
    I get this message while trying to install Ubuntu 12.04 as a guest in VirutalBox 4.1.18, on an Ubuntu 10.04 host. This kernel requires the following feature not present on the CPU: pae Some host specs: The host's kernel is: Linux 2.6.32-41-generic-pae GNU/Linux lscpu (host): Architecture: i686, CPU op-mode(s): 32-bit, 64-bit grep --color=always -i PAE /proc/cpuinfo   does show pae in its output. The 12.04 iso used is: ubuntu-12.04.0-desktop-i386.iso As a comparison/check, I downloaded and installed Linux Mint 13 Cinnamon to the same host on the exact same VM (I just changed the .iso image). It worked fine. Its iso is: linuxmint-13-cinnamon-dvd-32bit.iso It seems (to me) that I have pae.. what is going on here? Update: I had assumed that Linux Mint also required pae (being Ubuntu based), but I've just run;   grep --color=always -i PAE /proc/cpuinfo   in the Mint VM.   It showed no output.   So it seems the issue may lie with VirtualBox.   If that is the case, how can I get Virtualbox into pae mode?

  • Testing a codebase with sequential cohesion

    - by iveqy
    I've this really simple program written in C with ncurses that's basically a front-end to sqlite3. I would like to implement TDD to continue the development and have found a nice C unit framework for this. However I'm totally stuck on how to implement it. Take this case for example: A user types a letter 'l' that is captured by ncurses getch(), and then an sqlite3 query is run that for every row calls a callback function. This callback function prints stuff to the screen via ncurses. So the obvious way to fully test this is to simulate a keyboard and a terminal and make sure that the output is the expected. However this sounds too complicated. I was thinking about adding an abstraction layer between the database and the UI so that the callback function will populate a list of entries and that list will later be printed. In that case I would be able to check if that list contains the expected values. However, why would I struggle with a data structure and lists in my program when sqlite3 already does this? For example, if the user wants to see the list sorted in some other way, it would be expensive to throw away the list and repopulate it. I would need to sort the list, but why should I implement sorting when sqlite3 already has that? Using my orginal design I could just do an other query sorted differently. Previously I've only done TDD with command line applications, and there it's really easy to just compare the output with what I'm expected. An other way would be to add CLI interface to the program and wrap a test program around the CLI to test everything. (The way git.git does with it's test-framework). So the question is, how to add testing to a tightly integrated database/UI.

  • An equivalent of IceCast but for Live Video Streaming ?

    - by Kedare
    Hello, I am looking for a solution to Stream live video like that : A camera/webcam/video output ---> Stream server ---> Clients And if possible multiple Stream Servers like this (like IceCast): A camera/webcam/video output --> Master Stream server +---> Slave Stream Server ---> Clients | `--> Clients | `--> Slave Stream Server ---> Clients `--> Clients The clients will be in flash, so I think RTMP should be a good protocol, I've heard of Red5, is it good for that ? Does it scale ? I would like to get statistics (Amount of clients, Bandwidth, etc), is it possible with red5 ? Do you know any other good solution to do that ? (Only free and if possible Open Source) Thank you !

  • NIC is receiving, but not transmitting at all?

    - by Shtééf
    I'm trying to fix a very strange problem remotely on a machine at a customer site. The machine is a Dell PowerEdge, I believe a 1950 (haven't verified, but the lspci output matches specs I found.) The machine has two similar NICs, identified as Broadcom Corporation NetXtreme II BCM5708 Gigabit Ethernet (rev 12) by lspci, and using the bnx2 driver. (I suspect these are on-board and on the same controller, which is what I'm accustomed to for this type of machine.) The primary interface eth0 works perfectly, and is in fact how I am ssh'd in. However, the secondary interface eth1 is not transmitting. I can see this in ifconfig output, for example, where the TX field is always 0. However, it is receiving, and tcpdump shows ARP requests coming from the ISP's gateway on the other side. The interface is physically connected to a Siemens BSTU4 modem, configured by the ISP. The link is properly set to 10MBps and full duplex, without negotation, as the ISP requested. A small /30 subnet is configured. For the sake of anonimity, let's say the machine is 3.3.3.2/30, and the ISP's gateway .1. The machine has no firewall settings whatsoever. Even running something like arping -I eth1 3.3.3.1, and running tcpdump alongside, shows no traffic whatsoever being transmitted on the interface. (But the other side keeps steadily sending ARP requests, and that is all that can be seen.) What could be causing this? Here's some output, anonymized, which may hopefully help: $ ethtool eth1 Settings for eth1: Supported ports: [ TP ] Supported link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Full Supports auto-negotiation: Yes Advertised link modes: Not reported Advertised auto-negotiation: No Speed: 10Mb/s Duplex: Full Port: Twisted Pair PHYAD: 1 Transceiver: internal Auto-negotiation: off Supports Wake-on: d Wake-on: d Link detected: yes $ ip link show eth1 3: eth1: <BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast qlen 1000 link/ether 00:15:c5:xx:xx:xx brd ff:ff:ff:ff:ff:ff $ ip -4 addr show eth1 3: eth1: <BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast qlen 1000 inet 3.3.3.2/30 brd 3.3.3.3 scope global eth1 $ ip -4 route show match 3.3.3.0/30 3.3.3.0/30 dev eth1 proto kernel scope link src 3.3.3.2 default via 10.0.0.5 dev eth0

  • Errors in ~/.xsession-errors

    - by Kuberan Naganathan
    I'm getting errors in ~/.xession-errors. I'm running ubuntu 12.04 Many apps fail to run without mention of problems in the .xsession-errors file. I looked around and tried to resolve issues myself but failed so far. I have to say it's possible that the issue is related to me mounting /home on another partition.

    I'm trying to monitor disks on windows 2008 R2 system, but I'm getting wrong values returned from hrStorageSize and hrStorageUsed for one of the 2 disks the system has. Local disk C: is returning correct values, whereas D: disk, which is an SAN disk, is reporting 32G instead of 500G.

  • VPC SSH port forward into private subnet

    - by CP510
    Ok, so I've been racking my brain for DAYS on this dilema. I have a VPC setup with a public subnet, and a private subnet. The NAT is in place of course. I can connect from SSH into a instance in the public subnet, as well as the NAT. I can even ssh connect to the private instance from the public instance. I changed the SSHD configuration on the private instance to accept both port 22 and an arbitrary port number 1300. That works fine. But I need to set it up so that I can connect to the private instance directly using the 1300 port number, ie. ssh -i keyfile.pem [email protected] -p 1300 and 1.2.3.4 should route it to the internal server 10.10.10.10. Now I heard iptables is the job for this, so I went ahead and researched and played around with some routing with that. These are the rules I have setup on the public instance (not the NAT). I didn't want to use the NAT for this since AWS apperantly pre-configures the NAT instances when you set them up and I heard using iptables can mess that up. *filter :INPUT ACCEPT [129:12186] :FORWARD ACCEPT [0:0] :OUTPUT ACCEPT [84:10472] -A INPUT -i lo -j ACCEPT -A INPUT -i eth0 -p tcp -m state --state NEW -m tcp --dport 1300 -j ACCEPT -A INPUT -d 10.10.10.10/32 -p tcp -m limit --limit 5/min -j LOG --log-prefix "SSH Dropped: " -A FORWARD -d 10.10.10.10/32 -p tcp -m tcp --dport 1300 -j ACCEPT -A OUTPUT -o lo -j ACCEPT COMMIT # Completed on Wed Apr 17 04:19:29 2013 # Generated by iptables-save v1.4.12 on Wed Apr 17 04:19:29 2013 *nat :PREROUTING ACCEPT [2:104] :INPUT ACCEPT [2:104] :OUTPUT ACCEPT [6:681] :POSTROUTING ACCEPT [7:745] -A PREROUTING -i eth0 -p tcp -m tcp --dport 1300 -j DNAT --to-destination 10.10.10.10:1300 -A POSTROUTING -p tcp -m tcp --dport 1300 -j MASQUERADE COMMIT So when I try this from home. It just times out. No connection refused messages or anything. And I can't seem to find any log messages about dropped packets. My security groups and ACL settings allow communications on these ports in both directions in both subnets and on the NAT. I'm at a loss. What am I doing wrong?

  • How do I stop video tearing? (Nvidia prop driver, non-compositing window manager)

    - by Chan-Ho Suh
    I have that problem which seemingly afflicts many using the proprietary Nvidia driver: Video tearing: fine horizontal lines (usually near the top of my display) when there is a lot of panning or action in the video. (Note: switching back to the default nouveau driver is not an option, as its seemingly nonexistent power-management drains my battery several times faster) I've tried Totem, Parole, and VLC, and tearing occurs with all of them. The best result has been to use X11 output in VLC, but there is still tearing with relatively moderate action. Hardware: MacBook Air 3,2 -- which has an Nvidia GeForce 320M. There are two common fixes for tearing with Nvidia prop drivers: Turn off compositing, since Nvidia proprietary drivers don't usually play nice with compositing window managers on Linux (Compiz is an exception I'm aware of). But I use an extremely lightweight window manager (Awesome window manager) which is not even capable of compositing (or any cool effects). I also have this problem in Xfce, where I have compositing disabled. Enabling sync to VBlank. To enable this, I set the option in nvidia-settings and then autostart it as nvidia-settings -l with my other autostart programs. This seems to work, because when I run glxgears, I get: $ glxgears Running synchronized to the vertical refresh. The framerate should be approximately the same as the monitor refresh rate. 303 frames in 5.0 seconds = 60.500 FPS 300 frames in 5.0 seconds = 59.992 FPS And when I check the refresh rate using nvidia-settings: $ nvidia-settings -q RefreshRate Attribute 'RefreshRate' (wampum:0.0; display device: DFP-2): 60.00 Hz. All this suggests sync to VBlank is enabled. As I understand it, this is precisely designed to stop tearing, and a lot of people's problem is even getting something like glxgears to output the correct info. I don't understand why it's not working for me. xorg.conf: http://paste.ubuntu.com/992056/ Example of observed tearing::

  • How can I render a semi transparent model with OpenGL correctly?

    - by phobitor
    I'm using OpenGL ES 2 and I want to render a simple model with some level of transparency. I'm just starting out with shaders, and I wrote a simple diffuse shader for the model without any issues but I don't know how to add transparency to it. I tried to set my fragment shader's output (gl_FragColor) to a non opaque alpha value but the results weren't too great. It sort of works, but it looks like certain model triangles are only rendered based on the camera position... It's really hard to describe what's wrong so please watch this short video I recorded: http://www.youtube.com/watch?v=s0JqA0rZabE I thought this was a depth testing issue so I tried playing around with enabling/disabling depth testing and back face culling. Enabling back face culling changes the output slightly but the problem in the video is still there. Enabling/disabling depth testing doesn't seem to do anything. Could anyone explain what I'm seeing and how I can add some simple transparency to my model with the shader? I'm not looking for advanced order independent transparency implementations. edit: Vertex Shader: // color varying for fragment shader varying mediump vec3 LightIntensity; varying highp vec3 VertexInModelSpace; void main() { // vec4 LightPosition = vec4(0.0, 0.0, 0.0, 1.0); vec3 LightColor = vec3(1.0, 1.0, 1.0); vec3 DiffuseColor = vec3(1.0, 0.25, 0.0); // find the vector from the given vertex to the light source vec4 vertexInWorldSpace = gl_ModelViewMatrix * vec4(gl_Vertex); vec3 normalInWorldSpace = normalize(gl_NormalMatrix * gl_Normal); vec3 lightDirn = normalize(vec3(LightPosition-vertexInWorldSpace)); // save vertexInWorldSpace VertexInModelSpace = vec3(gl_Vertex); // calculate light intensity LightIntensity = LightColor * DiffuseColor * max(dot(lightDirn,normalInWorldSpace),0.0); // calculate projected vertex position gl_Position = gl_ModelViewProjectionMatrix * gl_Vertex; } Fragment Shader: // varying to define color varying vec3 LightIntensity; varying vec3 VertexInModelSpace; void main() { gl_FragColor = vec4(LightIntensity,0.5); }

  • Are there any free Windows based BluRay players out there?

    - by joshcomley
    I have a BluRay drive in my PC, and I'm wondering what the cheapest way to actually get it to play a movie is (I didn't expect this to be trouble). I'm using Windows 7. I installed CyberLink PowerDVD 8 (I'm currently downloading 10 but it's taking a very, very long time) and I get the below "error" when trying to watch a BluRay movie: CyberLink PowerDVD is not able to play the protected content on your digital output device. Please switch to an analog output (VGA, D-Sub) and then try again. I can't get VLC to play it and my research yields no plugins for VLC to enable it either - unless I'm vastly missing something. Help!

  • having trouble setting up ganglia on three machines

    - by Pieter Breed
    I am running ubuntu 11.10 I have one machine with gmetad, gmond and ganglia-webinterface. When I browse the web interface this machine picks up the local gmond output. I then added another machine, running only gmond. I didn't really change anything in the config, only the name of the cluster. This machine's output showed up in the web view. The I tried to add a third machine, similarly to the second, but it's not showing up in the web view. I tried looking at syslog and running as a daemon, but I'm not seeing anything suspicious there. Any tips for trouble shooting this?

  • No colors when running native windows shell application from mintty

    - by Pete
    Hi. I have installed cygwin (i'm not very experienced with it), and try to run a native windows shell application from it, (msbuild.exe which is the build tool for the .NET framework, to be exact). When I run the application from the normal cygwin bash shell, the output of the application appear as it should with the text colors that I would normally see in the windows command line. But when I execute the program from a mintty terminal, there is no coloring of the output, all text is in the default foreground color. I'm puzzled, because I would have expected the color coding to be the standard ANSI color code escape characters... Can this be fixed?
