  • How do I get rid of this drive mount confirmation question when booting the computer?

    - by Dave M G
    With help from this site, I was able to set up an SSHFS connection between two computers on my LAN so that one auto mounts on the other at boot time. Everything works, but there is this annoying confirmation that comes up whenever I boot: An error occurred while mounting /home/dave/Mythbuntu. Press S to skip mounting or M or Manual recovery If I press S, then booting continues, and my drive is mounted as hoped, so it seems like even though I "skipped" it, maybe it tried again and succeeded later in the boot process. I followed the instructions here to set up "if up / if down" scripts, and here is my current /etc/fstab: sshfs#[email protected]:/home/mythbuntu /home/dave/Mythbuntu fuse auto,users,exec,uid=1000,gid=1000,allow_other,reconnect,transform_symlinks,BatchMode=yes 0 0 Although the mounting is working, this step of having to press S every time I boot is obviously kind of a hassle. How do I configure my computer so I don't have to do that, and so that my other computer will still automount?

  • java framework for a web wizard

    - by snippl
    I'd like to create a web wizard or a wizard on/within a website. I know there are several java frameworks for wizards but there is none for the web in particular. If I search for a framework, I always get wizards to create a website, applet, servlet and what not. But never how to create such a wizard itself. So the question(s) is: What framework should I use to create a web wizard? And what frameworks are there? The wizard will be the visualisation for a BPEL Process deployment on a apache ode. I thought a webapp would be an easy way because the apache is running anyway. I'm not bound to that, perhaps someone has a better idea.

  • Where should the database and mail parameters be stored in a Symfony2 app?

    - by Songo
    In the default folder structure for a Symfony2 project the database and mail server credentials are stored in parameters.yml file inside ProjectRoot/app/config/parameters.yml with these default values: parameters: database_driver: pdo_mysql database_host: 127.0.0.1 database_port: null database_name: symfony database_user: root database_password: null mailer_transport: smtp mailer_host: 127.0.0.1 mailer_user: null mailer_password: null locale: en secret: ThisTokenIsNotSoSecretChangeIt During development we change these parameters to the development database and mail servers. This file is checked into the source code repository. The problem is when we want to deploy to the production server. We are thinking about automating the deployment process by checking out the project from git and deploy it to the production server. The thing is that our project manager has to manually update these parameters after each update. The production database and mail servers parameters are confidential and only our project manager knows them. I need a way to automate this step and suggestion on where to store the production parameters until they are applied?

  • What issues carry the highest risk in a software project?

    - by Mehrdad
    Clearly, software projects are different from other industries in terms of many things like for instance, quality assurance, project progress measurement, and many other things. Unique characteristics of software projects also makes the risk management process unique. Lots of issues in a project might lead it to unacceptable delay or failure to deliver business value. They might even make a complete disaster in the project. What are the deadliest risk factors in a software project? How to analyze, prevent and handle them? Particularly, I'm interested in the issues that you can detect from the beginning and you should keep an eye on (for example, you might be told about a third-party API that the current application uses and lacks documentation). Please share your experiences if they are relevant.

  • Is the copy/paste approach professionally viable when working with the Google Maps API?

    - by Ian Campbell
    I find that I understand much of the Javascript concepts used in the Google Maps API code, but then again there is quite a bit that is way over my head in syntax. For example, the geocoder syntax seems to be of Ajax form, though I don't understand what is happening under the hood (especially with lines like results[0].geometry.location). I am able to modify the body of if (status == google.maps.GeocoderStatus.OK) for different purposes though. So, being that I am able to take various code from the Developer's Guide and rework it to an extent for my own purposes, all the while not fully understanding what Google Maps is actually doing, does this make me a copy-paste programmer? Is this a bad practice, or is this professionally viable? I am, of course, interested in learning as much as I can, but what if time-constraints outweigh the learning process?

  • At what point should data be sent back to server?

    - by whamsicore
    A good example would be the stackexchange "rate" button. When a post is upvoted the arrow changes color immediately. However there is a grace period for one to edit one's vote decision (oops! voted by mistake?). Is the upvote action processed immediately or does is only process after a set time period, or when the user leaves the page? How exactly is this rating processed? What is the standard for handling dynamic page edits (e.g. stackexchange rating, facebook posts?)

  • Removing mdadm array and converting to regular disks while preserving data

    - by Jeffrey Kevin Pry
    I have a 6 disk (2TB each) mdadm RAID 5 volume created in Ubuntu 12.04 Server. However, I'm moving to a different solution and want to "unraid" my disks but keep the data. Only 50% is in use. From what I can surmise I basically have to do this recursively for each physical disk. Fail the disk Format the failed disk Move a portion of files to the new disk. Reshape the array Shrink the logical volume md0 This seems like a very time consuming process. Is there an easier way to do this (automatically perhaps) without buying new disks to temporarily hold the data? I am also aware that during this processing my RAID volume will be degraded and vulnerable the entire time. I am not too concerned about this and will be using battery backup and moving the most important files off first. Thank you for your help!

  • Testing To Prevent Cascading Bugs

    - by jfrankcarr
    Yesterday, Twitter was hit with a "Cascading Bug" as described in this blog post: A “cascading bug” is a bug with an effect that isn’t confined to a particular software element, but rather its effect “cascades” into other elements as well. I've seen this kind of bug, on a smaller scale of course, on some projects I've worked on. They can be difficult to identify in dev/test environments, even within a test driven development environment. My questions are... What are some strategies you use, beyond the basic TDD and standard regression testing, to identify and prevent the potential trouble points that might only occur in the production environment? Does the presence of such problems indicate a breakdown in the software development process or simply a by-product of complex software systems?

  • A bacon- (and module-) saving PowerShell incident

    - by AaronBertrand
    Earlier today I made a big goof. I opened a module in Notepad, intending to use it as the basis for a new module. I was in the process of using "File > Save As" when my phone rang just at the precise instant that, for some reason, made me click on "File > Save" by mistake. After hitting Ctrl+Z 30 times to try to get the old version of the module back, I remembered that Notepad has never had more than one level of Undo. Back when I was coding ASP by hand, I was very well aware of this, but I...(read more)

  • What could be a reason for cross-platform server applications developer to make his app work in multiple processes?

    - by Kabumbus
    So we consider a server app development - heavily loaded with messing with big data streams.An app will be running on one powerful server. a server app shall be developed in form of crossplatform application - so to work on Windows, Mac OS X and Linux. So same code many platforms for standing alone server architecture. We wonder what benefits does distributing applications not only over threads but over processes as wall would bring to programmers and to server end users and why? Some people sad to me that even having 48 cores, 4 process threads would be shared via OS throe all cores... is it true BTW?

  • Do PHP-FPM (and other PHP handlers) need execute permissions on the PHP files they're serving?

    - by Andrew Cheong
    I read in a post at Server Fault that PHP-FPM needs execute permissions. However, the answer in When creating a website, what permissions and directory structure? only grants read and write permissions to PHP-FPM. Maybe I don't quite understand how PHP handlers (or CGI in general) work, but the two claims seem contradictory to me. As I understand, when Apache / Nginx gets a request for foobar.php, it "passes" the file to an appropriate handler. That is, I imagine it's as if www-root (or apache or whomever the webserver's running as) were to run some command, /usr/sbin/php-fpm foobar.php Actually, no, that's naive, I just realized. PHP-FPM must be a running instance (if it's to be performant, and cache, etc.), so probably PHP-FPM is just being told, "Hey, quick, process this file for me!" In either case, I don't see why execute permissions are necessary. It's not like the webserver needs to literally execute the file, i.e. ./foobar.php Is the Server Fault answer simply mistaken?

  • Scheme of work contract

    - by Tommy
    I'm in the process of setting up a (one man) company and got to a item on my list "contracts and insurance". I will primary be offering custom software development but may also offer some "open source solutions", install, configure / manage e.t.c. I'm not sure how to approach a contract with a potential customer. I want to be flexible and offer the customer rights over the product (when not using open source of course) but I obviously want / need to be able to reuse code, already written and any future work. Is this possible or is it just something that people do but strictly they shouldn't? Is there a standard freelancing / contacting developer agreement? Going to a lawyer I'm sure is an answer but a very expensive one! If not do you end up with a fresh contract with each job / client and lots of trips to solicitors?

  • open source database project

    - by Jeff V
    What is the best way to build an open source database? I would like to build a database of all vehicles and the related maintenance information (i.e Oil Weight, Quantity, Tire Pressure, Windshield wipers etc). Currently this information is fragmented or just not put on line in an open way. Once collection began I would want to import into a DB and then be able to distribute freely. Is there a process (site or group) that I can start gathering this information in a reliable and verifiable way? Is there any issues that I should watch out for?

  • How can Java be improved so that it no longer needs to perform type erasure? [closed]

    - by user63904
    The official Java tutorial on generics explains type erasure and why it was added to the compiler: When a generic type is instantiated, the compiler translates those types by a technique called type erasure — a process where the compiler removes all information related to type parameters and type arguments within a class or method. Type erasure enables Java applications that use generics to maintain binary compatibility with Java libraries and applications that were created before generics. This most likely was a pragmatic approach, or perhaps the least painful one. However, now that generics is widely supported across the industry, what can be done in order for us to not need type erasure? Is it feasible with out needing to break backwards compatibility, or if it is feasible, is it practical? Has the last the last statement in the quote above become self referential? That is: "type erasure enables Java applications that use generics to maintain binary compatibility with Java libraries and applications that were created with Java versions that perform type erasure."

  • Help building pygtk application

    - by umpirsky
    This is my application. It is created with quickly. I would like to package it for Ubuntu now. I tried to package it with uickly, but that failed. At first, I was trying to install it using setup.py. But it is only copied in python lib dir, no icon, no desktop file installed. Then I tried to follow this guide, but I ended up with package without icon and it was of bad quality, but most important of all, it does not use setup.py, and it was pretty complicated. I would like to automate packaging process Can someone point me in the right direction, some examples of existing apps that have automated packaging etc? Thanks in advance.

  • Profiling NetBeans 7.0 Beta 2 and Reporting Problems

    - by christopher.jones
    With NetBeans 7.0 recently going into Beta 2 phase, now is the time to test it out properly and report issues. The development team has been squashing bugs, including memory issues with the PHP bundle.There are some great new PHP related features in NetBeans 7.0, so you know you want to try it out.If you identify something wrong with NetBeans, please report it following the guidelines http://wiki.netbeans.org/IssueReportingGuidelinesDepending on the issues, data to attach to the report is mentioned on: http://wiki.netbeans.org/FaqLogMessagesFile and http://wiki.netbeans.org/FaqProfileMeNowIf you have a memory issue then a memory dump would also be useful. Run the jmap tool for this. There is some background information on http://wiki.netbeans.org/FaqMemoryDump. Here's how I used it.First I set my environment to match the JDK used by NetBeans. In my case I am using a nightly build so the JDK is in the configuration file under $HOME/netbeans-dev-201102210501:$ egrep netbeans_jdkhome $HOME/netbeans-dev-201102210501/etc/netbeans.conf netbeans_jdkhome="/home/cjones/src/jdk1.6.0_24" $ export JAVA_HOME=/home/cjones/src/jdk1.6.0_24 $ export PATH=$JAVA_HOME/bin:$PATH Next, I found the correct process number to examine:$ ps -ef | egrep 'netbeans|jdk'cjones   23230     1  0 16:07 ?        00:00:00 /bin/bash /home/cjones/netbeans-cjones   23438 23230  2 16:07 ?        00:00:09 /home/cjones/src/jdk1.6.0_24/binFinally I used the parent JDK process as the jmap argument:$ jmap -histo:live 23438 num     #instances         #bytes  class name----------------------------------------------   1:         12075        9028656  [I   2:         49535        6581920  <constMethodKlass>   3:         49535        3964128  <methodKlass>   4:         80256        3840776  <symbolKlass>   5:         36093        3635336  [C   6:          5095        3341312  <constantPoolKlass>   7:          5095        2486016  <instanceKlassKlass>   8:          4325        1961432  <constantPoolCacheKlass>   9:         18729        1763976  [B  10:         59952        1438848  java.util.HashMap$Entry  . . .This histogram memory report will help identify the kind of memory issues you are seeing. It may not be as complete as an often tens of megabyte jmap -dump:live,file=/tmp/nbheap.log 23438 heap dump, but is much more easily attached to a bug report.If you want to keep up to date with NetBeans, nightly builds are at: http://bits.netbeans.org/download/trunk/nightly/latest/zip/

  • Are "Compile to JavaScript" Frameworks Hostile to Continuous Integration?

    - by joshin4colours
    Lately we've been looking at ways to improve automated testing and related tooling of our enterprise-level GWT web app. I've realized that in some ways, GWT is a bit hostile to automated testing, mainly because of the nature of the long GWT compile times from Java to JS. This makes unit testing somewhat challenging, but it also puts some roadblocks up for testing in a CI environment. I've also found out that some of our build and deployment processes are somewhat complicated due to the nature of GWT's compile process. Is this a general problem for "compile to JS" frameworks for webapps? I don't have much experience with them, but I can see some potential problems for automated testing and continuous integration and deployment. Some issues I see: Long build and compile times preventing quick deployments Language the app is developed in != JS, preventing good unit testing Obfuscated JS in the actual app makes it more like a executable than a web app Are these issues present in other similar frameworks, or is this more a GWT issue?

  • Ubuntu 12.04 boot freezes

    - by Lajos Soukup
    I installed win7 on one of my machines. It works without any problem. Now I can not install Ubuntu 12.04 (11.10, 11.04) because the installation process stops in a very early stage: I can see that ISOLinux was loaded, then I can see some very simple icons, then I can see text messages of the kernel. The last message I can see: [6.177983] sr 5:0:0:0: attached scsi general ss1 type 5 At that point the system stops. I tried different versions (11.04) , I disabled, and then disconnected the hdd, but the same problem occured independently from my actions. I can boot a gparted live cd, but that system can not see my hdd. On the other hand, I can boot the installation cd of the latest stable Debian distribution without any problem, but I would prefer to use Ubuntu, because I use that distribution on all of our machines.s Configuration: Asus P8H61-MLE motheboard, Gigabyte GTS 450, Intel i5, 4gb ram, wd 1T sata hdd Any idea? Best regards, Lajos

  • Slow wifi after upgrading kubuntu 13.04 to 13.10

    - by RedCow22
    After upgrading from kubuntu 13.04 to 13.10 suddenly my wifi connection is very slow. Ping times are varying from 200 up to 1500 ms to www.google.nl. When I connect my ethernet cable they drop to normal times like 8 or 9 ms. Anyone experiencing the same problem or know a solution I can try? During the upgrade process a few times they asked whether I wanted to keep or replace some kind of configuration file. I'm not sure anymore which file it was, but maybe this has something to do with it. Before the upgrade both wired and wireless connection worked perfect.

  • Upgrade to 14.04 broke gsettings

    - by zrneely
    I have a cron job which runs every 30 minutes that changes the background image by running this bash script: #!/bin/bash export DISPLAY=:0 export GSETTINGS_BACKEND=dconf wpdir="/home/username/Pictures/wallpapers/" prefix="file://" file=`ls $wpdir | shuf -n 1` gsettings set org.gnome.desktop.background picture-uri "$prefix$wpdir$file" This worked perfectly until I upgraded to 14.04. Now, running the script produces this output: (process:27459): dconf-WARNING **: failed to commit changes to dconf: Could not connect: Connection refused What can I do to fix this? Google didn't turn up any useful results. EDIT: I noticed that running this does change the background displayed on the lock screen, but it does not affect the desktop background.
