  • systray-whitelist changes are only temporary (how do i make them permenant?)

    - by Ed Sweeney
    I am writing a Qt C++ app. The notifications from trayIcon->showMessage(title, message) show up fine after I run the following command and logout/login: gsettings set com.canonical.Unity.Panel systray-whitelist "['all']" But after a few minutes the notifications don’t display any more and I have to repeat the gsettings logout/login. How can I get unity to play my messages without this fooling around when my user installs my app? Thanks for any help!

  • Can web applications running on IIS7 Windows Server 2008 R2 be forced to immediately detect changes to hosts file?

    - by Brenda Bell
    We have several web applications running on several load-balanced servers. We want to have our web applications communicate with each other without first traversing outside the load balancer. For example: http://appA.example.com is running on 192.0.2.1 and 192.0.2.2 http://appB.example.com is also running on 192.0.2.1 and 192.0.2.2 The load balancer's public IP address is 198.51.100.3 By default, when appA on 192.0.2.1 makes a call to a WCF service hosted in appB, the HTTP request is routed to 192.51.100.3; this establishes a new session and the load balancer will direct the call to either of the two servers We want the call to be routed to the instance of appB running on the same server so we add 192.0.2.1 appB.example.com to the hosts file on 192.0.2.1. This eventually works, but we either have to wait for the app pool to naturally recycle or do a manual reset before appA sees the new address. Is there any way to have the change automatically detected without having to recycle the app pool?

  • How do I stop color changes when quitting vi from a terminal emulator?

    - by Michael Warhol
    I have a problem with colors when using vi under Ubuntu 12.04. I'm connecting to my Ubuntu server from a PC, using PowerTerm terminal emulation software. I have PowerTerm set up to display black text on a grey background. When I connect to the Ubuntu box, the screen is fine. When I open a file with vi, the screen is fine. The text is black on a gray background, which is normal for my PowerTerm setup. However, if the file is less than a full screen long, the remainder of the screen is a black background. When I quit vi, the entire background turns black, and the text becomes white. I have to do a Terminal Reset to restore my normal text and background colors. What I want is for there to be no change at all when I use vi. The text should be black and the background grey. I have another server loaded with RedHat 9, and that acts normally; colors don’t change when using vi. Here is my .vimrc file: set compatible syntax off let g:loaded_matchparen=1 set nocp set noincsearch set nohlsearch set noshowmatch set bg=dark I've tried set bg=dark and set bg=light. It makes no difference. Is there some other set command that would clear this up for me, or some TERM setting (my TERM is set to linux)?

  • Sites with overlapping code-bases. Developing multiple sites with little changes

    - by Web Developer
    I have to develop 3 different sites video.com for hosting video audio.com for hosting audio docs.com for hosting docs. domain names for example only Almost 80% of the functionality is the same for all the three, with remaining 20% being completely different features... How do I handle this? How does sites like SO handle this? I am developing this in YII framework and was thinking of having these different features as modules but in this case the menu/code links in html code can become difficult.

  • Ubuntu Server 11.10 AMD64: Installation of graphical desktop changes kernel!?

    - by MindGap
    I've a Ubuntu Server 11.10 amd64 installation that needed a graphical desktop to execute some visual apps. While searching for the correct way to achive this, I noticed that there was a lot of people saying that invoquing the gnome desktop installation (apt-get install ubuntu-desktop) would switch from server to desktop kernel. Is this true!? I've checked and the kernel seems to remain unchanged after the install. I need to be sure of this because the desktop flavoured kernel doesn't seem to support the ServeRaid 8K controller sitting on my IBM server and I have no ideia on how to enable support for it. (I'll be grateful if someone could point me a good guide on how to install ubuntu when the storage controller is not detected) Any comment on this matter will be greatly appreciated! Good linuxing!

  • How can I better manage far-reaching changes in my code?

    - by neuviemeporte
    In my work (writing scientific software in C++), I often get asked by the people who use the software to get their work done to add some functionality or change the way things are done and organized right now. Most of the time this is just a matter of adding a new class or a function and applying some glue to do the job, but from time to time, a seemingly simple change turns out to have far-reaching consequences that require me to redesign a substantial amount of existing code, which takes a lot of time and effort, and is difficult to evaluate in terms of time required. I don't think it has as much to do with inter-dependence of modules, as with changing requirements (admittedly, on a smaller scale). To provide an example, I was thinking about the recently-added multi-user functionality in Android. I don't know whether they planned to introduce it from the very beginning, but assuming they didn't, it seems hard to predict all the areas that will be affected by the change (apps preferences, themes, need to store account info somehow, etc...?), even though the concept seems simple enough, and the code is well-organized. How do you deal with such situations? Do you just jump in to code and then sort out the cruft later like I do? Or do you do a detailed analysis beforehand of what will be affected, what needs to be updated and how, and what has to be rewritten? If so, what tools (if any) and approaches do you use?

  • Which VCS is efficient for storing small changes to big text files?

    - by MiguelM
    A government agency publishes a text file with thousands of records. The entire file is about 60MB. Every day the file has about 60 new or changed records. We need to validate some info against that file, and for auditing purposes, we may need to recover the file as it was in certain date. I thought I could use a VCS to store the file using git, but I understand git stores the entire text file gzipped, so the 60BM file will still need about 30MB to store everyday version. I wonder if one of the free VCS stores only diff/patch files.

  • SEO and search result changes when switching to SSL on Joomla site?

    - by jeffery_the_wind
    I am thinking about purchasing an SSL certificate for a website. The most noticeable difference for the user would be the http now becomes https and there is that lock icon in most browsers. Will there be any adverse affects on the website's current SEO or recognition by search engines when I make the switch? Also this is a Joomla site, which has an option in the settings to use SSL. It is supposed to make it easier but not sure if it takes care of everything. Thanks!

  • How can I change the percent of screen brightness that changes every time I press the shortcut?

    - by Chriskin
    When I press Fn+F6 the change in brightness is too big. How can I make it move less than it does now? (Let's say, half that, for example.) (11.04/Gnome. I'm on proprietary nvidia drivers.) EDIT: I haven't tried what Rinzwind has written below because , after throwing a cup of coffee on my laptop, my keyboard was destroyed (so i no longer have the FN button that is needed - i'm currently writing from an external one). I have already ordered a new one and i will collect it from the service center tomorrow at noon

  • How do you balance business process changes against the challenges of changing software?

    - by Achilles
    In my admittedly young career I've found myself writing code to support quirky business rules and processes. Inevitably these changes were always in some massively difficult code base and caused many issues. My question has a couple of parts: While software is a tool for businesses to make their lives easier, at what point do we as developers suggest a change in business process rather than in the software as the "magic bullet" to solve a particular problem. How do we as developers evangelize a certain level of reverence for the software as well as the difficulty involved in making changes simply to support the quirks of the business? I understand that these changes in business processes promote our industry, but in an analogy my father would understand: Which is easier, to melt down a hammer to forge a screwdriver to drive screws or to simply use nails since your hammer is already awesome...?

  • Parallel port no longer accessible even though no changes to system.

    - by marcusw
    I have an old Dell Dimension 8200 running Gentoo which I use solely to control various things using the parallel port. After shutting it down a few weeks ago, I started it up again today and tried to access the parallel port like I usually do. Unfortunately, my code bombed out when it tried to call ioperm(888,1,1) to grab the parallel port which returned an error code of -1. There have been no changes to the system be it hardware or software, no updates, no tweaking, no dropping the case, no over-amping the data pins, nothing. The port and the software have been working fine for months with no changes, and were working fine when I shut it down last. Running my code with root privileges changes nothing. What is breaking this and how can I fix it?

  • Svn: revert file content changes without reverting any related mergeinfo?

    - by George Hawkins
    If you've done a merge you may find, before committing the changes, that actually you don't want to accept any of the changes merged into one of the affected files. So you do e.g.: $ svn revert foo.c However this also seems to revert the mergeinfo related to this file. So when you do a subsequent merge it will merge in exactly the same changes again. Rather than revert one could do: $ svn cat foo.c foo.c But this doesn't seem like the right way to do things? Is there something that more clearly indicates what I'm trying to achieve, i.e. to say "consider the merge done for this file but don't change its contents"?

  • How to Track Number of Changes Occured in a Column? T-SQL - SQL Server

    - by user327387
    For example, i have a column named EmployeeName. Every time a user changes/fix his name, i need to keep a count. If he changes his name twice, then count is 2. Also, i need to store the time of every change employee makes on EmployeeName e.g. if the name essentially is James and time created is 9:00 AM and then employee changes to John on 11:00 AM, i need to preserve this new time and new value as well as the previous one which is James at 9:00 AM. I hope its clear! Thank you guys...Best Answer will be chosen... If this requires a trigger, giving a sketchy pseudo-code will be very much appreciated.

  • When a server IP changes, do exising TCP (e.g. http/mysql) connections remain running

    - by Luke Cousins
    We have some PHP-FPM servers and when they need a database connection, they connect to an HAProxy server which selects them a database server to use and the connection opens. When we then want to perform some maintenance on the HAProxy servers (such as config changes requiring an HAProxy restart), the process is as follows: Shutdown Keepalived on the HAProxy server Wait for the floating IP to transfer to the backup HAProxy server (also running Keepalived) Wait until HAProxy stats is reporting just one connection (us checking how many connections there are) Restart HAProxy Restart Keepalived As step 2 occurs, what will happen to the open mysql connections at that point? According to this TCP Sessions and IP Changes question the connections will be dropped. Is this really the case? If so, what, if anything, can be done to prevent this happening? Can the connection be in some way forced to use the main (non-floating) IP of the server? We also have a similar setup with two Nginx servers with Keepalived running on them and we were planning on doing the equivalent process. If we do, the same question applies - what happens to the existing http connections when the IP moves to the other server? I appreciate your help.

  • OpenGL ES, UIView and Status Bar mess

    - by sfider
    I have iPhone (iPhoneOS 3.x) OpenGL ES app that: can be in landscape/portrait orientation can be with/without status bar shown I do this by changing status bar orientation and hidden state, then updating OpenGL view frame so it won't overlap status bar and setting projection matrix appropriately. OpenGL view is in portrait orientation at all time. View controller's shouldAutorotateToInterfaceOrientation: method returns false always, so the status bar won't start autorotating when app is in landscape mode. The problem I have is that I want to use some other UIViews, like: UIWebView, MFMailComposeView, MPMediaPicker. I could show them as modals, but this this have some drawbacks: views will always show in portrait orientation, even if they support landscape orientation views will not autorotate, even if they support it What I do is I take OpenGL view of the window with removeFromSuperview, set transform to the other view so it will be in portrait/landscape orientation when it shows up and place the other view on the window with addSubview:. This works fine without the status bar, but with it there are some problems I cannot work out: MPMediaPicker is sized to fit under status bar, but it slides under it anyway MFMailComposeView does not show navigation bar until it autorotates on device orientation change Does anyone has an idea how can I get it to work?

  • JQuery display problems?

    - by DuH
    I'm new to JQuery and was wondering how can I have Changes saved! displayed only once even if the user presses the submit button multiple times for example if a user decides to change there info three different times the text, Changes saved!Changes saved!Changes saved! is displayed i only want Changes saved! displayed once. How can I fix this problem? What part of my code needs to be fixed? Here is the JQuery code. $(function() { $('#changes-saved').hide(); $('.save-button').click(function() { $.post($('#contact-form').attr('action'), $('#contact-form').serialize(), function(html) { $('div.contact-info-form').html(html); $('#changes-saved').append('Changes saved!').show(); }); $('a').click(function () { $('#changes-saved').empty(); $('#changes-saved').hide(); }); return false; // prevent normal submit }); });

  • What's the best way to explain branching (of source code) to a client?

    - by Jon Hopkins
    The situation is that a client requested a number of changes about 9 months ago which they then put on hold with them half done. They've now requested more changes without having made up their mind to proceed with the first set of changes. The two sets of changes will require alterations to the same code modules. I've been tasked with explaining why them not making a decision about the first set of changes (either finish them or bin them) may incur additional costs (essentially because the changes would need to be made to a branch then if they proceed with the first set of changes we'd have to merge them to the trunk - which will be messy - and retest them). The question I have is this: How best to explain branching of code to a non-technical client?

  • Where do I find a list of changes and bug fixes for .Net classes from 3.5 -> 4.0?

    - by Nathan Ridley
    I'm having trouble finding a list of the changes and bug fixes that have been made in the .Net framework for .Net 4.0. They're not easy to find, but surely they exist somewhere? Specifically I want to find out what changes and updates have been made for System.Net.HttpWebRequest and System.Net.CookieContainer, as both are quite bugridden in 3.5 and I want to evaluate whether I should write my code for .Net 4.0 or if I should create some custom classes to work around their issues.

  • How do I minimize the number of changes between revisions with new doxygen output?

    - by Dirk Eddelbuettel
    A subversion repository contains the html, latex and man directories that doxygen generates from the source code. Even for small source code changes, new files are being generated with random names which makes for large changes in the version control system. Is there are way around this? How can I minimize the changesets between revisions while still including doxygen-generated documentation? Alternatively, how could I find which of the doxygen-genrated files are no longer being used and should be removed?

  • Tracking upstream svn changes with git-svn and github?

    - by Joseph Turian
    How do I track upstream SVN changes using git-svn and github? I used git-svn to convert an SVN repo to git on github: $ git svn clone -s http://svn.osqa.net/svnroot/osqa/ osqa $ cd osqa $ git remote add origin [email protected]:turian/osqa.git $ git push origin master I then made a few changes in my git repo, committed, and pushed to github. Now, I am on a new machine. I want to take upstream SVN changes, merge them with my github repo, and push them to my github repo. This documentation says: "If you ever lose your local copy, just run the import again with the same settings, and you’ll get another working directory with all the necessary SVN metainfo." So I did the following. But none of the commands work as desired. How do I track upstream SVN changes using git-svn and github? What am I doing wrong? $ git svn clone -s http://svn.osqa.net/svnroot/osqa/ osqa $ cd osqa $ git remote add origin [email protected]:turian/osqa.git $ git push origin master To [email protected]:turian/osqa.git !

  • Name that blog entry - Modelling changes over time with two db columns only.

    - by disown
    I vaguely remember reading a blog entry (written by a well-known blogger I think) about how to model price changes over time, and that you could model most changes by saving two dates only (two columns in a db). The blog talked about prices on a website changing over time and how you could figure out the right price to charge knowing only when the purchase had been made. Very vague, I know, but my google-fu is failing me, everyone at IRC are busy talking about other stuff and I don't know what to do! :)
