  • aide --init show lots of errors

    - by newbie14
    I have a brand new centos 6.2 server. The first thing I did is yum -y install aide and then next I did aide --init. Below is a whole lot of errors I got.What does it means must I reinstall it?

  • Does Google use any “Language” flags / tags set within a PDF file when determining its language?

    - by Ally Ak
    When determining the language of a HTML page, I understand that Google looks at any language declarations that the page owner has set, and then also applies its own language detection algorithms. But does Google similarly look at language meta data set in PDF files when determining a PDF file's language? (Authors of PDF files can set document-wide properties describing the language (or languages) contained within it.) Or does Google rely exclusively on language detection algorithms and disregard the language flag set within the PDF file? Can anyone shed any light?

  • How to set the default language in Notepad++

    - by AngryHacker
    I mostly use Notepad++ for dealing with XML files. It would be good if Notepad++ parsed and colorized my files based on the XML language when I open the files. Instead, I have to open the file, pick XML from the Languages menu. Is there a way to tell Notepad++ that XML is the default language and to treat the files accordingly.

  • What makes a bad programming language bad?

    - by sub
    We have all seen things like the typing system of JavaScript (There is a funny post including a truth table somewhere around here). I consider this one of the main things that makes a programming language bad. Other things that spring to mind: Bad Error messages (Either obfuscated so you can't figure out whats wrong, not existing or simply too long and red) The language wasn't planned and just grew uncontrolled in all directions (PHP?) The language encourages bad programm(er/ing) habits such as: Global variables everywhere, bad variable names Inconsistent naming conventions inside the language I can't come up with any more at the moment and would be very happy to read what you think about this. What shouldn't be missing in a language created to be as bad (from the perspectives of the programmer, the company that hires to programmer, the team leader and the customer) as possible? (I ask this because I'm designing a bad, experimental language at the moment)

  • Video editing language

    - by wvd
    Hi folks, My next project will be all about language tools, parsing and such. Because of that reason I've decided to write a simple language which can be used for video editing. So instead of those desktop applications (Sony vegas, Adobe Premiere, ..) it's basically a language where you define the effects and all and it will generate a video for you. Since I've got no experience in this kind of business I need some help. The goal of the project is to create a simple language which is able to do some basic things (such as text fading in, etc). I am looking for articles/projects/blogs/whatever related with this which could help me writing this language. (Note that I don't need articles about language parsing since I'm pretty familar with that, just the video editing part). Thanks, William v. Doorn

    I recently saw a programming language called supernova and they said in the web page : The Supernova Programming language is a modern scripting language and the First one presents the concept of programming with direct Fiction Description using Clear subset of pure Human Language. and you can write code like: i want window and the window title is Hello World. i want button and button caption is Close. and button name is btn1. btn1 mouse click. instructions are you close window end of instructions my question is not about the language itself but it is that are we need such languages and did they make writing code easier or not?

  • TFS API-Process Template currently applied to the Team Project

    - by Tarun Arora
    Download Demo Solution - here In this blog post I’ll show you how to use the TFS API to get the name of the Process Template that is currently applied to the Team Project. You can also download the demo solution attached, I’ve tested this solution against TFS 2010 and TFS 2011.    1. Connecting to TFS Programmatically I have a blog post that shows you from where to download the VS 2010 SP1 SDK and how to connect to TFS programmatically. private TfsTeamProjectCollection _tfs; private string _selectedTeamProject;   TeamProjectPicker tfsPP = new TeamProjectPicker(TeamProjectPickerMode.SingleProject, false); tfsPP.ShowDialog(); this._tfs = tfsPP.SelectedTeamProjectCollection; this._selectedTeamProject = tfsPP.SelectedProjects[0].Name; 2. Programmatically get the Process Template details of the selected Team Project I’ll be making use of the VersionControlServer service to get the Team Project details and the ICommonStructureService to get the Project Properties. private ProjectProperty[] GetProcessTemplateDetailsForTheSelectedProject() { var vcs = _tfs.GetService<VersionControlServer>(); var ics = _tfs.GetService<ICommonStructureService>(); ProjectProperty[] ProjectProperties = null; var p = vcs.GetTeamProject(_selectedTeamProject); string ProjectName = string.Empty; string ProjectState = String.Empty; int templateId = 0; ProjectProperties = null; ics.GetProjectProperties(p.ArtifactUri.AbsoluteUri, out ProjectName, out ProjectState, out templateId, out ProjectProperties); return ProjectProperties; } 3. What’s the catch? The ProjectProperties will contain a property “Process Template” which as a value has the name of the process template. So, you will be able to use the below line of code to get the name of the process template. var processTemplateName = processTemplateDetails.Where(pt => pt.Name == "Process Template").Select(pt => pt.Value).FirstOrDefault();   However, if the process template does not contain the property “Process Template” then you will need to add it. So, the question becomes how do i add the Name property to the Process Template. Download the Process Template from the Process Template Manager on your local        Once you have downloaded the Process Template to your local machine, navigate to the Classification folder with in the template       From the classification folder open Classification.xml        Add a new property <property name=”Process Template” value=”MSF for CMMI Process Improvement v5.0” />           4. Putting it all together… using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Windows.Forms; using Microsoft.TeamFoundation.Client; using Microsoft.TeamFoundation.VersionControl.Client; using Microsoft.TeamFoundation.Server; using System.Diagnostics; using Microsoft.TeamFoundation.WorkItemTracking.Client; namespace TfsAPIDemoProcessTemplate { public partial class Form1 : Form { public Form1() { InitializeComponent(); } private TfsTeamProjectCollection _tfs; private string _selectedTeamProject; private void btnConnect_Click(object sender, EventArgs e) { TeamProjectPicker tfsPP = new TeamProjectPicker(TeamProjectPickerMode.SingleProject, false); tfsPP.ShowDialog(); this._tfs = tfsPP.SelectedTeamProjectCollection; this._selectedTeamProject = tfsPP.SelectedProjects[0].Name; var processTemplateDetails = GetProcessTemplateDetailsForTheSelectedProject(); listBox1.Items.Clear(); listBox1.Items.Add(String.Format("Team Project Selected => '{0}'", _selectedTeamProject)); listBox1.Items.Add(Environment.NewLine); var processTemplateName = processTemplateDetails.Where(pt => pt.Name == "Process Template") .Select(pt => pt.Value).FirstOrDefault(); if (!string.IsNullOrEmpty(processTemplateName)) { listBox1.Items.Add(Environment.NewLine); listBox1.Items.Add(String.Format("Process Template Name: {0}", processTemplateName)); } else { listBox1.Items.Add(String.Format("The Process Template does not have the 'Name' property set up")); listBox1.Items.Add(String.Format("***TIP: Download the Process Template and in Classification.xml add a new property Name, update the template then you will be able to see the Process Template Name***")); listBox1.Items.Add(String.Format(" - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -")); } } private ProjectProperty[] GetProcessTemplateDetailsForTheSelectedProject() { var vcs = _tfs.GetService<VersionControlServer>(); var ics = _tfs.GetService<ICommonStructureService>(); ProjectProperty[] ProjectProperties = null; var p = vcs.GetTeamProject(_selectedTeamProject); string ProjectName = string.Empty; string ProjectState = String.Empty; int templateId = 0; ProjectProperties = null; ics.GetProjectProperties(p.ArtifactUri.AbsoluteUri, out ProjectName, out ProjectState, out templateId, out ProjectProperties); return ProjectProperties; } } } Thank you for taking the time out and reading this blog post.

  • PyQt: How to Know Progress of a Process Running background

    - by krishnanunni
    Hello there. Im in real confusion with the ProgressBar mechanisms. However now i need help on this "Can we know the percentage completion or time remaining of completion of a Process, that has been initiated from a Qt interface like this ` self.process = QProcess() self.connect(self.process, SIGNAL("readyReadStdout()"), self.readOutput) self.connect(self.process, SIGNAL("readyReadStderr()"), self.readErrors) tarsourcepath="sudo tar xvpf "+ self.path1 self.process.setArguments(QStringList.split(" ",tarsourcepath)) self.textLabel3.setText(self.__tr("Extracting.....")) self.process.start()` slots readOUtput just implements the collection of data fron stdout and transferring it to a text browser. I need to know is there any way we could monitor the ongoing process, making to knowpercentage completion, so that i can manage a progressbar for this. Thanks Experts

  • How to tell process id within Python

    - by R S
    Hey, I am working with a cluster system over linux (www.mosix.org) that allows me to run jobs and have the system run them on different computers. Jobs are run like so: mosrun ls & This will naturally create the process and run it on the background, returning the process id, like so: [1] 29199 Later it will return. I am writing a Python infrastructure that would run jobs and control them. For that I want to run jobs using the mosrun program as above, and save the process ID of the spawned process (29199 in this case). This naturally cannot be done using os.system or commands.getoutput, as the printed ID is not what the process prints to output... Any clues? Edit: Since the python script is only meant to initially run the script, the scripts need to run longer than the python shell. I guess it means the mosrun process cannot be the script's "son process". Any suggestions? Thanks

  • (C#) How do you de-elevate permissions for a child process

    - by Davy8
    I know how to launch a process with Admin privileges from a process using: proc.StartInfo.UseShellExecute = true; proc.StartInfo.Verb = "runas"; where proc is a System.Diagnostics.Process. But how does one do the opposite? If the process you're in is already elevated, how do you launch the new process without admin privileges? More accurately, we need to launch the new process with the same permission level as Windows Explorer, so no change if UAC is diabled, but if UAC is enabled, but our process is running elevated, we need to perform a certain operation un-elevated because we're creating a virtual drive and if it's created with elevated permissions and Windows explorer is running unelevated it won't show up. Feel free to change the title to something better, I couldn't come up with a good description

  • Linux process management

    - by tanascius
    Hello, I started a long running background-process (dd with /etc/urandom) in my ssh console. Later I had to disconnect. When I logged in, again (this time directly, without ssh), the process still seemed to to run. I am not sure what happened - I did not use disown. When I logged in later, the process was not listed in top at first, but after a while it reclaimed a high CPU percentage, as I expected. So I assume dd is still running. Now, I'd like to see the progress. I use kill -USR1 <pid> but nothing is printed. Is there any way to get the output again?

  • automatic IIS worker process recycle fails

    - by Sander Rijken
    The server is set to its default configuration to recycle the app pool every 1740 minutes. When this happens the following message is logged: A worker process with process id of '1234' serving application pool 'XX' has requested a recycle because the worker process reached its allowed processing time limit. Directly after logging this message, the web site is unresponsive. The only way to get it back online is by running iisreset manually. Does anyone know a fix for this behavior, other than turning the recycle feature off? Is it a known problem?

  • Monitoring and terminating a hanged process in Linux

    - by Yoav
    Hi, I'm writing a script that runs many simultaneous processes that run the "dig" command. Once in a while (relatively rare, but happens in every run since I run dig many times) the dig command hangs with 0% CPU. Therefore, my script never terminates. I've created a monitor process for each dig command I run, which terminates it after a while, but I was wondering if there isn't a simpler and more efficient way to run a process with a pre-determined "expiration date", i.e. if the process runs more then X seconds it gets a signal that terminates it. Thanks!

    I am in a similar situation as in this post But I couln't get the solution provided there to work in my situation as the answer seems related to that question only. In particular, I couldnt understand what was the purpose of cat my.fifo | nc remotehost.tld 10000 In my case, I have a process running and waiting for input. how can I send input to that process using named pipes? I've tried echo 'h' > /proc/PID/fd/0 it just displays 'h' on the process' window.

  • top process state column under FreeBSD

    - by Eric DANNIELOU
    When running top interactively, I can see various word in the state column : nanslp, biord, select, uwait, lockf, pause, kqread, piperd, sbwait ... Some like nanslp or kqread are self explanatory, others are not. Tried man pages : STATE is the current state (one of "START", "RUN" (shown as "CPUn" on SMP systems), "SLEEP", "STOP", "ZOMB", "WAIT", "LOCK" or the event on which the process waits), C is the processor number on which the process is executing (visible only on SMP systems) Tried search engines : stack overflow mailing lists archives Where may I get a complete list of possible process state under FreeBSD 9, and their meanings?

  • Using Process Monitor to track registry changes

    - by CChriss
    It seems many people like using Process Monitor to see what changes are being made to the registry during a process. So I downloaded it. I want to see what changes are made in the registry by some config changes I'm making on my computer so I can write them into a vbs script to do them easily. Can someone tell me how to drive Process Monitor to capture the info? In the Help I don't see how to do it. I'm using Windows 7 home Premium 64 bit.

  • Natural talent vs experience [on hold]

    - by Tord Johansson Munk
    Hi i have a question for you guys if you had a choice of hiring one of two programmers. One of them is a natural born programming talent, he has been programming since he was 14 year old and he has been programming all sorts of things by him self, 3d renders,games,his own frameworks, he is really good at algorithms and problem solving. He is now about 25 years old and is looking for a job after some unchallenged years of college the only experience he has is working on his own/university stuff and some open source project. This guy spends all his free time programming and has several pet projects at home. The other person is a 37 year old career programmer. He has been programming since he graduated from university at the age of 26 and have been working since then. He did not have an interest in programming before university. During his studies he discovered that programming was fun and challenging but it never was a "passion". During his career he mainly worked with "enterprise" platforms such as .net or javaEE. He mainly have done database business applications and thus is lacking skills of the young talent like abstract problem solving or algorithms. But he know the tools he has been using during the years and is reliable and almost always makes his boss happy. He keeps him self updated in the platform and tools he has and is using. But outside the office walls he don't touch any code at all. Witch one would you hire? Would you favor one of them in certain projects? Do you think that if the young talent learns his tools he will be a better programmer than the older one? Would your decision be different if both of them where lacking a degree? or if only one of them was lacking a degree be the old and experienced or the young genius.

  • Interactive Data Language, IDL: Does anybody care?

    - by Alex
    Anyone use a language called Interactive Data Language, IDL? It is popular with scientists. I think it is a poor language because it is proprietary (every terminal running it has to have an expensive license purchased) and it has minimal support (try searching for IDL, the language, right now on stack) . I am trying to convince my colleagues to stop using it and learn C/C++/Python/Fortran/Java/Ruby. Does anybody know about or even care about IDL enough to have opinions on it? What do you think of it? Should I tell my colleagues to stop wasting their time on it now? How can I convince them? Edit: People are getting the impression that I don't know or use IDL. Also, I said IDL has minimal support which is true in one sense, so I must clarify that the scientific libraries are indeed large. I use IDL all the time, but this is exactly the problem: I am only using IDL because colleagues use it. There is a file format IDL uses, the .sav, which can only be opened in IDL. So I must use IDL to work with this data and transfer the data back to colleagues, but I know I would be more efficient in another language. This is like someone sending you a microsoft word file in an email attachment and if you don't understand how wrong that is then you probably write too many words not enough code and you bought microsoft word. Edit: As an alternative to IDL Python is popular. Here is a list of The Pros of IDL (and the cons) from AstroBetter: Pros of IDL Mature many numerical and astronomical libraries available Wide astronomical user base Numerical aspect well integrated with language itself Many local users with deep experience Faster for small arrays Easier installation Good, unified documentation Standard GUI run/debug tool (IDLDE) Single widget system (no angst about which to choose or learn) SAVE/RESTORE capability Use of keyword arguments as flags more convenient Cons of IDL Narrow applicability, not well suited to general programming Slower for large arrays Array functionality less powerful Table support poor Limited ability to extend using C or Fortran, such extensions hard to distribute and support Expensive, sometimes problem collaborating with others that don’t have or can’t afford licenses. Closed source (only RSI can fix bugs) Very awkward to integrate with IRAF tasks Memory management more awkward Single widget system (useless if working within another framework) Plotting: Awkward support for symbols and math text Many font systems, portability issues (v5.1 alleviates somewhat) not as flexible or as extensible plot windows not intrinsically interactive (e.g., pan & zoom) Pros of Python Very general and powerful programming language, yet easy to learn. Strong, but optional, Object Oriented programming support Very large user and developer community, very extensive and broad library base Very extensible with C, C++, or Fortran, portable distribution mechanisms available Free; non-restrictive license; Open Source Becoming the standard scripting language for astronomy Easy to use with IRAF tasks Basis of STScI application efforts More general array capabilities Faster for large arrays, better support for memory mapping Many books and on-line documentation resources available (for the language and its libraries) Better support for table structures Plotting framework (matplotlib) more extensible and general Better font support and portability (only one way to do it too) Usable within many windowing frameworks (GTK, Tk, WX, Qt…) Standard plotting functionality independent of framework used plots are embeddable within other GUIs more powerful image handling (multiple simultaneous LUTS, optional resampling/rescaling, alpha blending, etc) Support for many widget systems Strong local influence over capabilities being developed for Python Cons of Python More items to install separately Not as well accepted in astronomical community (but support clearly growing) Scientific libraries not as mature: Documentation not as complete, not as unified Not as deep in astronomical libraries and utilities Not all IDL numerical library functions have corresponding functionality in Python Some numeric constructs not quite as consistent with language (or slightly less convenient than IDL) Array indexing convention “backwards” Small array performance slower No standard GUI run/debug tool Support for many widget systems (angst regarding which to choose) Current lack of function equivalent to SAVE/RESTORE in IDL matplotlib does not yet have equivalents for all IDL 2-D plotting capability (e.g., surface plots) Use of keyword arguments used as flags less convenient Plotting: comparatively immature, still much development going on missing some plot type (e.g., surface) 3-d capability requires VTK (though matplotlib has some basic 3-d capability)

  • parent process, and a child process..

    - by icelated
    I am trying to write a program that The parent process will take the arguments to main() and send the characters in them one at a time to the child process through a pipe (one call to write for each character). The child process will count the characters sent to it by the parent process and print out the number of characters it received from the parent. The child process should not use the arguments to main() in any way whatsoever. The child should return normally and not have the parent kill the child. Am i counting the arguments right? am i sending the arguments in one at a time, and am i reaping the child? #include <sys/wait.h> #include <stdio.h> #include <stdlib.h> #include <unistd.h> #include <string.h> #define size = 100; int main(int argc, char *argv[]) { int i, count =0; int c; int fdest[2]; // for pipe pid_t pid; //process IDs char buffer[BUFSIZ]; if (pipe(fdest) < 0) /* attempt to create pipe */ perror( "pipe" ); if ((pid = fork()) < 0) /* attempt to create child / parent process */ { perror( "fork" ); } /* parent process */ else if (pid > 0) { close(fdest[0]); for (i=1; i < argc; ++i) { for (c=0; c < strlen(argv[i]); ++c) { write(fdest[1], &argv[i][c], 1); } } close(fdest[1]); wait(NULL); exit(0); } else { /* child Process */ close(fdest[1]); while (read(fdest[0], &buffer, 1) > 0) { count++; } printf("\nchild: counted %d characters\n", count); } wait(NULL); exit(0); }

  • Ignore non-unicode programs language when installing software

    - by mitya
    This is something that is driving me nuts for a while and I haven't been able to find a solution for this problem anywhere. I am running Windows 7 and my "Language for non-Unicode programs" setting is set to Russian. I need for some non-unicode software that has a Russian UI. However, for most of my software I prefer to use the English UI. A lot of software out there is multilingual and is too smart for my liking. When installing, it switches the UI to Russian and the software UI stays in Russian after the installation without an option to change that, besides setting the "non-unicode language" to English. It switches back to Russian once I revert the setting and reboot. Most of the time it is driver software, i.e: Intel, HP, etc. How can force the installation to run English and stay that way after install, ignoring the "Language for non-Unicode programs" setting? Now, I understand this might be specific to the installer: MSI, Install Shield, etc. But any solution will be good, even if I have to apply it for every software installation. Thanks in advance for any helpful information!

  • Word list sources

    - by warren
    I am looking for a source of nouns, adverbs, adjectives, and verbs in several languages. I'd like the lists to already be split apart, and not have to go through the OED (and non-English equivalents) by hand re-creating said lists. I don't really care about definitions, and I understand some words can be multiple parts of speech - that's fine - words like "many" could be a noun or adjective, and can appear in both lists. Does anyone here know of such a source? If not, might someone be able to point me in the right direction?
