• Best way to bring a system down with a "maintenance" message?

  - by iftrue

  What's the best way to bring down an apache2/tomcat6 setup for maintenance? Specifically, apache2 can stay running, but tomcat needs to restart to accomplish a number of tasks. My initial thought is to change the root directory in the httpd.conf VirtualHost entry to point to a new location, then issue a force-reload command to direct traffic away from the actual tomcat application. After some period of time, I perform tomcat maintenance, switch the VirtualHost entry, and force-reload to begin directing traffic back. Is there a better way to do this? I'm looking to start work on a rather extensive web application, and my deployment procedure right now involves shutting everything down and bringing everything back up. Is there a better way to do this than what I've proposed?

• Web browser downloads only open target folders - cannot open files

  - by Pavlos G.

  After installing xubuntu packages in order to check xfce, I reverted back to gnome2. During the first login, I noticed that thunar was now selected as the default file manager. Preferred applications menu is also missing now, so I could not set nautilus as the default. I removed all the xubuntu packages (including thunar) and then when I tried to open a folder, I was asked to select the default file manager - that's how I got nautilus back. The next problem I'm now facing has to do with the downloaded files from web browsers: Open and Open containing folder options produce exactly the same result. If I double-click on a file, it'll just open the containing folder, instead of opening the file with it's associated application (e.g. libreoffice writer for .doc,.odt, smplayer for .avi,.wmv, etc). The problem happens both in Firefox and Chrome. Through nautilus, all files open correctly. Up until now I've tried the following: Delete/recreate mimeTypes.rdf in my FF profile Create a new profile in FF Delete/recreate ~/.local/share/applications/mimeapps.list Already checked this similar article None of them worked. Any ideas on the issue would be appreciated.

• Rotating wheel with touch adding velocity

  - by Lewis

  I have a wheel control in a game which is setup like so: - (void)ccTouchesMoved:(NSSet *)touches withEvent:(UIEvent *)event { UITouch *touch = [touches anyObject]; CGPoint location = [touch locationInView:[touch view]]; location = [[CCDirector sharedDirector] convertToGL:location]; if (CGRectContainsPoint(wheel.boundingBox, location)) { CGPoint firstLocation = [touch previousLocationInView:[touch view]]; CGPoint location = [touch locationInView:[touch view]]; CGPoint touchingPoint = [[CCDirector sharedDirector] convertToGL:location]; CGPoint firstTouchingPoint = [[CCDirector sharedDirector] convertToGL:firstLocation]; CGPoint firstVector = ccpSub(firstTouchingPoint, wheel.position); CGFloat firstRotateAngle = -ccpToAngle(firstVector); CGFloat previousTouch = CC_RADIANS_TO_DEGREES(firstRotateAngle); CGPoint vector = ccpSub(touchingPoint, wheel.position); CGFloat rotateAngle = -ccpToAngle(vector); CGFloat currentTouch = CC_RADIANS_TO_DEGREES(rotateAngle); wheelRotation += (currentTouch - previousTouch) * 0.6; //limit speed 0.6 } } I update the rotation of a the wheel in the update method by doing: wheel.rotation = wheelRotation; Now once the user lets go of the wheel I want it to rotate back to where it was before but not without taking into account the velocity of the swipe the user has done. This is the bit I really can't get my head around. So if the swipe generates a lot of velocity then the wheel will carry on moving slightly in that direction until the overall force which pulls the wheel back to the starting position kicks in. Any ideas/code snippets?

• MQTT, GWT, ActiveMQ stack to bring jms to the browser

  - by scphantm

  I am in the preliminary stages of architecting a legacy replacement project. They already have sub half second performance on their green screens and they want the same on their web app. We have a 390 mainframe that can handle anything we throw at it but they don't have a good jvm for it, so we have two tiers of websphere servers between the mainframe and the browser, The ui server, and the bl server. For the ui, I'm leaning towards GWT. But one thing that I think would seal the deal is to add messaging capabilities to the browser. The idea is say you click on a link that displays a second panel of information, instead of the classic GWT where it triggers a GWT-RPC call to the ui server, the ui server routs it to the bl server, the bl sends it to the mainframe and back out, it drops an MQTT message directly to the bl server or directly to the mainframe. Say writes go to the bl, reads go to the mainframe. This is an easy enough thing in classic jms because you can issue a message that has an expected response. Then have your callback ready to get the resonse. But from what I'm reading so far. It looks like mqtt doesn't have that. It looks like it's strictly fire and forget, which would make it really tough to come up with a way to get a response back to the workstation that called it. Am I right here? Has anyone tried this stack before with gwt.

• Making simple forms in web applications

  - by levalex

  How do you work with forms in your web applications? I am not talking about RESTful applications, I don't want to build heavy front-end using frameworks like Backbone. For example, I need to add "contact us" form. I need to check data which was filled by user and tell him that his data was sent. Requirements: I want to use AJAX. I want to validate form on back-end side and don't want to duplicate the same code on front-end side. I have my own solution, but it doesn't satisfy me. I make an AJAX request with serialized data on form submit and get response. The next is checking "Content-type" header. html - It means that errors with filling form are exists and response html is form with error labels. - I will replace my form with response html. json and response.error_code == 0 - It means that form was successfully submited. - I will show user notification about success. json and response.error_code != 0 - Something was broken on back-end (like connection with database). other - I display the following message : We have been notified and have started to work with that problem. Please, try it later. The problem of that way is that I can't use it with forms that upload file. What is your practise? What libraries and principles do you use?

• Failed to load session gnome-fallback, after messing with metacity

  - by Carlito

  I am using Ubuntu 12.04 with gnome-session-fallback (Gnome Classic in the login menu). I wanted to remove window borders from metacity and stumbled across this post which basically changes window->mwm_decorated from TRUE to FALSE, which should remove the window borders in metacity. I know that it is also possible to change your GTK theme to one without window borders, but I wanted to try this solution. So I downloaded the source from my current metacity version (2.34.1) and changed that row. After compiling (./configure && make) I ran checkinstall which generates a .deb file from the source (had to change the version a bit to match the current one exactly). But after installing and loging out and back in, I couldn't load Gnome Classic. I get the error Failed to load session gnome-fallback. I could reinstall the old metacity which was still saved in /var/cache/apt/archives/, so everything is back where it was before. But I would like to mess around with metacity. Have I installed it correctly or did I forgot something? Are there any log files that I should check for solving this error? Thanks in advance!

• I'm hoping to start an online supermarket and needs advice on open source shopping cart software and applications..

  - by Betterman Simidi

  I have been researching on both open source software and off-the-shelf software for an online supermarket project in Africa. I have now narrowed by search to X-cart and the PHP based PrestaShop shopping carts. My plan is to acquire an open source shopping cart either by purchasing or as a free open source cart and hire a local developer to customize it to our local needs. I have been doing the demo for x-cart for three weeks now and had thought it might work best for us but after going through the 600 page manual and I'm concerned with how far it can be localized. Yesterday i was looking at the possible Prestashop free open source cart and i seem to like the back-end. Didn't like the back-end for Magento much but from reviews conducted by third-parties they seem to recommend it. I'm now wondering whether i should have a developer start the whole project from scratch, or use an open source software such us PrestaShop or get x-cart which can then be customized. Note that my store will have thousands of products and services including groceries and so i want something that can handle upto 500,000 products and over. Kindly advice. 93276

• Gnome shell not starting at login, but can start from terminal (Ubuntu 12.04)

  - by Mat Leonard

  I upgraded to Ubuntu 12.04 recently and for some reason it broke Gnome 3. The shell doesn't start up at login. My .xsession-errors looks like this right after I log in: gnome-session[1689]: WARNING: Session 'gnome' runnable check failed: Timed out (gnome-settings-daemon:1744): color-plugin-WARNING **: failed to get edid: unable to get EDID for output (gnome-settings-daemon:1744): color-plugin-WARNING **: unable to get EDID for xrandr-default: unable to get EDID for output (gnome-settings-daemon:1744): color-plugin-WARNING **: failed to reset xrandr-default gamma tables: gamma size is zero ** Message: applet now removed from the notification area ** Message: using fallback from indicator to GtkStatusIcon ** Message: moving back from GtkStatusIcon to indicator Then I can run gnome-shell --replace, the shell starts up and everything works.

• Why is my ipad's wireless so flakey?

  - by Mark

  I'm the proud owner of a new IPad here in the UK. All is good, except for the wifi, which is a bit flakey. It connects fine to my Draytek router which is set for WPA/WPA2 and 56g only, displaying full signal strength. Then, after a few minutes, it goes down to minimum strength... And sometimes it goes back up again. A few times, it seems to loose connection completely, and needs to be turned off and on again. I've looked at the Apple support site, and have tried their recommendations (which are not really very relevant), but still nothing. I've tried setting the router to wpa2 only, and setting long-preamble. Right now, I guess I want to know if it's a hardware problem with my device and should be returned, or if it's a problem with all ipads which will be resolved. Guess I could take it back to the Mac genius bar, but I find those guys so incredibly pretentious and, frankly, rather useless, that i'd rather wait until I've exercised other options!

• Unity Dashboard won't find local files, rearrange icons on two computers

  - by Stanton.Sculpture

  Suddenly I can't move icons around my unity launcher and the Dash won't search for my local files and folders. Was working when I first installed 13.10, but now it won't search for local files, and it won't let me rearrange the icons in any way. I've tried turning on and off all the scopes (lenses?) in multiple combinations, but it won't find any files unless I use nautilus to find them its mostly unresponsive. I can't see my recently used files, or files and folders scope at all. Dragging and dropping the icons on the side dock doesn't work, they only stick to my mouse until I put them back where they were. I cannot unlock any icons from the launcher, it just doesn't do anything when I click it. I tried rebooting both of my computers and its still won't function normally. I used ubuntu-bug -w to report a bug, no one has gotten back to me. Is there some option that I changed to cause this? This is a problem on both my laptop and Desktop. Please Help, Alex

• I have a dead laptop, what are my options?

  - by Michael Kniskern

  After having my previous question answered by the HP technical support, I now have a HP laptop that does not work properly. HP recommended that I replace the motherboard and processor for a bargain price of $733 US dollars. I originally purchased this laptop back when the Windows Vista was released back in January 2007 for about $2,000 US dollar, but now is an very expensive paperweight. What are my options for this laptop? Do I try to revive it on my own.... What are your suggestions?

• Browser language detection & content ranking for new language on the same site.

  - by Arnaud

  I've been reading a lot about it but it's still really hard to make up my mind. My understand is that if your website provide a link to the other language, this should not be an issue for google as long as your links are clear and clean, google will be able to make his way through it. The website was orginaly in french and I added the english version and I'm just worry that english speaker will just leave if the site is not in the correct language, for the home page I just wanted to get the value from the browser and redirect it to /fr/ or /en/ for the first page. (using php this will be very easy) Could you guys have a look at it and tell me what you think about it http://tinyurl.com/bpc5bn9 I don't want to get it wrong and lost my ranking with google. Also the website has good rank on the french side and the english has been online for 2 weeks and only get few visit a day, is that because all the back link refer to /fr/ and google is cleaver enough to decide that they are 2 differantes website and the back link will have to point to /en/ to increase the ranking value? Or will take few more weeks for the website to grow? Thanks for your hep

• Weird console problem in linux, usually right before OOM

  - by Kevin Quinn

  So I've noticed this happen more than once. If I remember correctly, this usually happens right before OOM, and/or kernel panic that if you type into a tty and then try to backspace it, the same characters are printed back in reverse. This has been merely an interesting oddity to me in the past, but it happened again recently, and I've gotten more curious about what's actually causing that. (Is it sending the characters back to STD_OUT or something?) Does anyone have any idea? I have a feeling the answer will be interesting. Just so I'm clear, if you typed hello world, then tried to backspace it: hello world..dlrow olleh

• OS X 10.8.3 + attempt to change VPN settings = no more VPN access

  - by nicole

  I am running Mountain Lion and had gotten very tired of re-entering my password at random times when using my school's VPN network (I don't know much about these, but the type is Cisco IPSec according to the setup instructions I followed a while back). In an attempt to make life easier, I followed the instructions here, but, alas, any attempt to connect with VPN was met with the message "A configuration error has occurred. Verify your settings and try connecting again" (or something along those lines.) I then tried to do the steps in the blog post in reverse and change everything back. Upon (supposedly) doing that, though, a new error message came when attempting to connect to VPN: "The negotiation with the VPN server failed. Verify the server address and try reconnecting." Now I have no idea what to do. Is there a way to reset all VPN-related things in my system so that I can follow my school's instructions and just start over?

• LCD monitor reports incorrect maximum resolution

  - by SLaks

  I have four 20" Planar 2010M LCD monitors with a maximum resolution of 1600 x 1200 connected to two nVidia video cards (8600 GT and 7600 GS). I'm running Windows Server 2003 x86. Recently, two of the monitors have started mis-reporting their maximum resolution as 1280 x 1024. When this first happened, I used nVidia's Custom Resolutions feature to force the monitors back to 1600 x 1200. Yesterday, however, I upgraded nVidia's video card driver, and ever since, I cannot get the DVI one back to 1600 x 1200. When I add the custom resolution in nVidia's control panel, if I set either the width or the height to even a single pixel more than 1280 x 1024, nothing changes when I click Test (the monitor doesn't even flash black, although after 15 seconds, it flashes black and doesn't change). After adding Does anyone know what the problem is? Is there anything I can do about it?

• Cannot do sudo: "/etc/sudoers is mode 0740, should be 0440"

  - by dehmann

  I have a problem: I don't have a root password on my mac. I just have an Admin account, which can do stuff using sudo. Now, I wanted to add my normal user to the /etc/sudoers file as well. Since it did not let me write to that file (even writing using sudo), I did this: sudo chmod u+w /etc/sudoers That worked. But since then I can't do any sudo command anymore on my system. It complains that /etc/sudoers has the wrong mode: $ sudo touch /etc/sudoers sudo: /etc/sudoers is mode 0740, should be 0440 Segmentation fault It sounds like a bad joke, because now I can't even change the mode back to 0440: $ sudo chmod 0440 /etc/sudoers sudo: /etc/sudoers is mode 0740, should be 0440 Segmentation fault Is there any way to fix this situation? I need to get my sudo abilities back.

• Is there such a thing as "closure" with software work?

  - by Bobby Tables

  I burned out last year (after a decade of fulltime programming jobs) and am on a sabbatical now. With all the self-examination I've started to figure out some of the root causes of my burnout, and one of the major ones is basically this: there was never any real closure in any of the work I've ever done. It was always a case of getting into an open-ended support/maintenance grind and going stale. When I first entered the industry, I had this image of programming work being very project-based. And I expected projects to have a start, beginning, and END. And then you move on and start on something totally new and fresh. Basically I never expected that a lot (most) of software work involves supporting and maintaining the same code base for open-ended long periods of time - years and even decades. That, combined with generally having itchy feet makes me think that burnout is inevitable for me, after 2-3 years, in ANY fulltime software job. All this sounds like I probably should have been a contractor instead of a fulltimer. But when I discuss this with people, a lot of them say that even THEN you can't really escape having to go back and maintain/support the stuff you worked on, over and over (eg. Coming back on support contracts, for example). The nature of software work is simply like that. There is no project closure, unlike in many other engineering fields. So my question is - Is there ANY programming work out there which is based on short to mid term projects/stints and then moving on cleanly? And is there any particular industry domain or specialization where this kind of project work is typical?

• Moving a window from a disconnected monitor to connected monitor on Vista

  - by RickMeasham

  I have a laptop that runs Vista Mega Ultimate Amazing for Business 64-bit. When at work, I connect a monitor via USB (which totally rocks) to the "left" of the laptop monitor. It's identified as monitor 3. At home, I use an old CRT monitor that sits to the right of the laptop monitor. It's monitor 2. Monitor 1 is, of course, the inbuilt laptop monitor. Now at home I open a window, any window, on monitor 2. Then I come to work and plug in monitor 3. Anything I had open on monitor 2 is now stuck in unretrievable land. (Actually, it's probably anything that was minimised when I left home that belonged on monitor 2 will expand back onto monitor 2, even though it's disconnected) How can I get those windows back onto connected monitors?

• loading splash screen takes priority over terminal or windows manager while running elsa

  - by schonjones

  I recently installed e17 and was trying to set up defaults to use elsa and ecomorph over the standard compiz as it constantly crashes since updating to 12.04. If elsa is installed the loading screen hangs and never loads to login, however i can get to a terminal or the e17 login instead of the standard gdm that usually shows up, within a second the screen goes back to the loading screen. I can still type and login as well as run commands in the terminal, but all I see is the loading screen. Switching between terminals i can confirm my commands before it switches back to the loading screen. If i remove elsa the loading screen hangs, but I can get to a terminal login and run lightdm to start my session with no problems. I have multiple DE installed and am unsure which loading screen is coming up. i think it's the KDE screen, grub comes up with a debian background if that helps. I'm not sure if i can switch the loading screen and resolve this issue or if i'm just going to have to scrap using elsa and get lightdm to load on boot again. Elsa would be my preference. I don't have the space to backup my files for a complete reinstall. Please help!

• cocos2d event handler not fired when reentering scene

• Skynet Big Data Demo Using Hexbug Spider Robot, Raspberry Pi, and Java SE Embedded (Part 3)

  - by hinkmond

  In Part 2, I described what connections you need to make for this demo using a Hexbug Spider Robot, a Raspberry Pi, and Java SE Embedded for programming. Here are some photos of me doing the soldering. Software engineers should not be afraid of a little soldering work. It's all good. See: Skynet Big Data Demo (Part 2) One thing to watch out for when you open the remote is that there may be some glue covering the contact points. Make sure to use an Exacto knife or small screwdriver to scrape away any glue or non-conductive material covering each place where you need to solder. And after you are done with your soldering and you gave the solder enough time to cool, make sure all your connections are marked so that you know which wire goes where. Give each wire a very light tug to make sure it is soldered correctly and is making good contact. There are lots of videos on the Web to help you if this is your first time soldering. Check out Laday Ada's (from adafruit.com) links on how to solder if you need some additional help: http://www.ladyada.net/learn/soldering/thm.html If everything looks good, zip everything back up and meet back here for how to connect these wires to your Raspberry Pi. That will be it for the hardware part of this project. See, that wasn't so bad. Hinkmond

  I am not that good with programmation, but I guess you are. we are planning to install 2 display monitor in the back of the other one. There will be 1 computer that will display a different application on each display monitor. I want to be able to switch display 1 to 2 and display 2 to display 1 to show what is on the other monitor without having to move themselve on the back of the monitor to see the opposite monitor. I need a script that will switch display every x times. How can I do that ?

• How to refactor when all your development is on branches?

  - by Mark

  At my company, all of our development (bug fixes and new features) is done on separate branches. When it's complete, we send it off to QA who tests it on that branch, and when they give us the green light, we merge it into our main branch. This could take anywhere between a day and a year. If we try to squeeze any refactoring in on a branch, we don't know how long it will be "out" for, so it can cause many conflicts when it's merged back in. For example, let's say I want to rename a function because the feature I'm working on is making heavy use of this function, and I found that it's name doesn't really fit its purpose (again, this is just an example). So I go around and find every usage of this function, and rename them all to its new name, and everything works perfectly, so I send it off to QA. Meanwhile, new development is happening, and my renamed function doesn't exist on any of the branches that are being forked off main. When my issue gets merged back in, they're all going to break. Is there any way of dealing with this? It's not like management will ever approve a refactor-only issue so it has to be squeezed in with other work. It can't be developed directly on main because all changes have to go through QA and no one wants to be the jerk that broke main so that he could do a little bit of non-essential refactoring.
