  • What's your advice in getting Oracle Certified Professional Java Programmer certificate?

    - by den-javamaniac
    Hi. I'm intending to get the certification but not completely sure how to time effectively prepare myself. So I'm wondering if I can be advised on the matter, in particular I would like next questions to be answered: - What the basic learning/practicing plan should look like? - What book (set of books) should be considered? - What practical exercises should be performed? NOTE: I've got several years of corporate experience (mostly web apps, though), but I want to be 100% sure I'll pass the test (that's the reason the issue is raised).

  • How do I move (copy) my entire Ubuntu system to a different hard disk?

    - by boywithaxe
    The HDD I have my Ubuntu installed is about to fail. I would rather not lose 3 years worth of data, customisation and apps. I am looking for a way to move the complete system (SWAP included, because I'm not sure if I can relink the system to a new SWAP partition) to another HDD. But not the complete HDD< only the partition containing Ubuntu, to a partition on a different HDD. Basically I'd like to do what I've been able to do with Norton Ghost for my Windows install. I thought about using Clonezilla but I think I would have issues with GRUB (Especially trying to boot from a different UUID than what is in the conf file). do you know of any way this could be done? PS, my home directory is encrypted but that's not really an issue, because I can work around that. EDIT: changed the explanation to make it clearer

  • how to install gerix on ubuntu 12.04 using backtrack repositories?

    - by werever
    I got instructions from here, and I found several sites with similar instructions but somethig is wrong with the repositories on 12.04. This should work for 11.10 and previous versions. Any ideas how to install backtrack repos and some back track apps on 12.04? I read about downloading the .deb package for gerix and manually making the same folder structure that gerix uses on backtrack, then manually run the python script, but this way didn't work for me either. How can I get gerix installed and working on my Ubuntu 12.04 system?

  • How to make a minimal upgrade?

    - by wajed
    I use apt-get install --no-install-recommends ubuntu-desktop to install minimal desktop. I want to upgrade my system to the latest version (12.04) with it still being minimal. How do I do that? What I tried:- I tried Update Manager, and it gave me the Option to upgrade to 11.10 first, then to 12.04. What happened after I upgraded to 11.10 is that my desktop got bloated, and instead of the system using 500MB of RAM, now it uses about 1.5GB I can't even start apps anymore.

  • How to make Nautilus name column display at the width of the longest filename

    - by fred.bear
    Prior to a recent glytch where I lost some of my custom settings, Nautilus would open directories and display the name-column wide enough to show the longest filename on display. It did it dynamically; If I renamed a file to a longer or shorter name, the column was automatically adjusted to the new width.. It's not doing that now, and I have no idea how to get this function back.. UPDATE I hadn't mentioned it, but I am talking about the List view... I have been fossicing around in the GConf Editpr and came across a setting for Compact View which does exactly what I am referring to... but it only effects the Compact View... that setting is: gconf-editor /apps/nautilus/compact_view/all_columns_have_same_width ...but I can't find the setting for List View... I know the capability exists, because I've been using it until only a few days ago, when my system got hung up...

  • What's the difference in content between the Ubuntu and Lubuntu Software Centers? Why aren't winners of the app showdown available in the latter?

    - by vasa1
    What's the difference in content between the Ubuntu and Lubuntu Software Centers? I've seen this Are softwares installable on ubuntu also installable on lubuntu? which indicates that the content should be the same. However, I looked for Ridual, OrthCal, Cuttlefish and MenuLibre. While all four are available in the Ubuntu Software Center, they aren't listed in the Lubuntu Software Center. Will they eventually be listed? Who decides? I'm asking because one of the criteria in the apps showdown, if I understood correctly, was desktop integration. If by "desktop", Unity is specifically implied then it would make sense not including them in the Lubuntu Software Center. Is that correct? I'm on 12.04.

  • "Testing Plan Lite" for web project

    - by Emmmmm
    How do you draft a quick & easy "Testing Plan Lite" for a medium-sized web project (70k lines, 2 developers)? I've seen many tutorials/articles on methods of testing, but all seem cumbersome. For us, the goal is to be able to be able to divide up and delegate testing instructions to our friends for different project segments, browsers, etc. What's the quick & easy way to write test plans for web apps? (the 20 of the 20/80 rule) Thanks!

  • Can't read CDs, can't create USB... how do I install Ubuntu?

    - by user68080
    Hello everyone and thank you in advance for your time. I have troubles with the latest Ubuntu distribution: since I upgraded to 12.04 Ubuntu has started having troubles (internal errors, packages that crash repeatedly, I can't install new packages, Ubuntu Software Center crashes, Java apps that worked stopped working and display weird mistakes, files were corrupted... a mess). I ultimately decided to format everything and install 12.04 from scratch. I made a backup and everything, but now I have troubles installing ubuntu 12.04. Specifically, a CD I burned with Brasero that works on another PC is not read by my laptop (not at boot phase, nor inside Ubuntu), and when I try to create a USB with Ubuntu (following the instructions I found on the ubuntu site) Startup Disk Creator stops at 22% saying that "the codes do not match". Any idea on what to do next? No, I can't buy a new PC.

  • Detecting right-click on XAML GridView control item

    - by mbrit
    Leaving aside why you would ever want to do this in a touch-centric world, here's how you tell if the right-mouse button has been clicked on a GridView in XAML/WinRT/Metro-style. You have to retrieve a point relative to the UI element you're in, and then query its properties. void itemGridView_PointerPressed(object sender, PointerRoutedEventArgs e) { if (e.GetCurrentPoint(this).Properties.IsRightButtonPressed) { this.BottomAppBar.IsOpen = true; } } (The reason why you might want to do this can be explained by looking at any of the built-in Win8 apps. You can right-click any of the items on any list to bring up a context-sensitive AppBar.)

  • What would be topic for research in on edge of multiple processors / computers programming?

    - by Kabumbus
    I mean what is not already there? What can be developed in fiew month and give a breakthrue/ start a new leap in science of f multiple computers programming? What i see is already there MPI/ Bit torrent/Jabber protocols / APIs / servers for messaging LAN / wire and other infrastractural cabels for connecting Boost and analogs on evry OS in most languages for multithreading there are lots of CUDA like on computer frameworks for fast calculating on computers GPUs What I personally do not see out there is a crossplatform framework for multiple processes interaction. Meaning one that would allow easy creation of multyple processes running in paralell inside one hoster app on one machine. In level not harder than needed for threads creation (so no seprate server apps - just one lib doing it all) Is there ny such lib and what can you propose for research topic?

  • In what stage of development should comments be written?

    - by CurtisHx
    I'm a student working an internship at a larger company, writing small business apps in C#. I've noticed that I don't comment my code as I write it. Rather, I comment my code when I'm in the debugging stage of development. As I'm tracking down bugs, I'll run across a block that makes me think "hmm...that might confuse someone in the future. I'd better comment that", and I'll add the appropriate comments. All of my comments are done this way. Is this an appropriate way of commenting? Should comments be written as the code is written? Or does it really matter when the comments are written, as long as they adequately explain why this block is used?

  • How to revert to 10.04

    - by Keith Mastin
    Since "upgrading" to 12.10, the multitude of problems and slowness has wondering me , if I'm running windows, so I want to take it back to 10.04. Just some of the problems that we never had in 10.4: Can't play YouTube and chat at same time; Can't open more than 5 photos in GIMP without constant grayouts; Can't easily close apps or programs on desktop; Can't Use Avidimux and Audacity at same time, CPU load stays at 100%; New Gnome is not nearly as intuitive as classic, focus is all over the place, have to constantly switch to have the focus on right window of same program (either browser), etc. Do I need to wipe my system partition and start over, or is there an easier way to downgrade?

  • What should someone learn to become a great web-app builder by 2015

    - by rickdronkers
    My brother just started learning some html/css at school and he loves it. He asked me to give my advice on what languages to learn in order to build great web-apps by the time he leaves school. (2015 or something like that.) I did some research, and right now I want to tell him (in this particular order): HTML - HTML5 CSS - CSS3 Javascript - jQuery - AJAX PHP - Zend Framework MySQL Ruby - RoR I would like to know if this is correct before I waste his time. Stackoverflow seems like a place where people know the answer to these kind of questions ;). Thanks!

  • Web Search for a Hard Drive

    - by zecougar
    Here is the situation. Our organization has a fair amount of data in the form of documents, images, videos stored on a intranet server. We need to be able to expose these documents via some sort of search functionality on the intranet. Provide some mechanism to organize and tag the documents on hard disk. Ideally we'd also like to provide a unified search across documents on the google apps for business instance that we have. Any ideas on how to approach this problem ?

  • Strange behaviour when screencasting

    - by Luis Alvarado
    Since an update I did yesterday I am not able to screencast any video using Kazam, Recordmydesktop or even ffmpeg/aviconv. After the upgrade to some libraries (A normal update that showed in Update manager) the problem was this: When doing the screencast, scrolling inside an Apps window like Firefox, Chrome or Gedit is not shown. The video only shows the last image it recognized before I started scrolling. For example with Gedit, I have a lot of text on it and when I start to scroll down, the video only shows what I had in the beginning while I listen to myself talk about what is in the rest of the file (Which is not shown in the video). When opening a window, for example again Gedit or Chrome it might not show in the video, it will just show the desktop without the window opened. I do not see any error with dmesg, syslog or others. What can I check to debug this problem?

  • R12.0 Cash Management Consolidated Patch Collection (CPC) And R12.1 Cash Management Recommended Patch Collection (RPC)

    - by user793553
    If you have Oracle E-Business Suite's Cash Management (CE) application installed, you'll want to be sure to install the latest CPC (Consolidated Patch Collection) if you are using a R12.0 version of the apps, or the latest RPC (Recommended Patch Collection) for the R12.1 version of the apps. These collections give you all the fixes currently available for known issues in the specified versions of the application, including all of the latest Root Cause Analysis Fixes (RCAs)! What is an "RPC" (for R12.1 users)? Since the release of 12.1, a number of recommended patches for Oracle Cash Management have been made available as standalone patches to help address important business process issues. Adoption of these patches was highly recommended at the time, but not always implemented, so to further facilitate adoption of these patches, Oracle consolidated them into product-specific Recommended Patch Collections (RPCs) - a collection of recommended patches. They were created by Oracle Development with the following goals in mind: Stability: To address data integrity issues that have been identified by Oracle Development and Oracle Software Support as having the potential to interfere with the normal completion of important business processes (such as, period close, etc.). Root Cause Fixes (RCAs): To make available root cause fixes for known data integrity issues. Compact: To keep the file footprint as small as possible to help facilitate the install process and minimize testing. Granular: To compile the collection of patches based on functional areas, allowing a customer to apply multiple RPCs at once, or in phases (based on individual needs and goals). Where to start ALL R12 Cash Management users (R12.0 and R12.1 users) should start with the following Note on My Oracle Support (MOS): Doc ID 1367845.1: R12: Cash Management Recommended Patch Collections It's a great place for important implementation information about both sets of critical patch collections! For R12.1x users R12.1 users should also take a look at the documents below for even more information about the RPC for the R12.1.x versions of the Cash Management application, and other related available RPCs: Note Number  Title                                                                                                      1489997.1 Master Troubleshooting Guide for CE: Reconciliation & Clearing [VIDEO] 954704.1 EBS: R12.1 Oracle Financials Recommended Patch Collections (RPCs) 1316506.1 R12: Oracle CE: Upgrading from R11i to R12.1: Latest Recommended Patches Patch Wizard Utility While a patch may contain several hundred files, the impact on your system may actually be minimal. Patches contain hard prerequisites that are intended to make a patch work on a very low code baseline. The Patch Wizard Utility will give you a detailed analysis of the patch’s impact on your instance BEFORE it’s applied, so you’ll know exactly what to expect from the application. Please refer to Doc ID 976188.1 for more information on this important utility

  • How to Stop Browser from rejecting my downloads

    - by melki0795
    I have a portfolio site where I am trying to host some of my work, so people can download my work. Some of these files include exe executables, and some are jar executables, which are run through batch. When a user tries to download my apps, it says that the file is not commonly downloaded and may be harmful, and therefore blocks the download. If I zip the folders, it still does the same thing. Any format i choose, still blocks the downloads. How can I stop chrome from doing this. Is there a way I can verify my files so they will be considered as trusted? Thanks in advance!

  • How far can you get in iOS without learning PhotoShop or another graphic design program? [on hold]

    - by Aerovistae
    I'm in the process of learning iOS, and I'm coming from a web dev background where CSS controls 70-90% of the UI, and Python/C++ desktop dev where there are highly customizable UI toolkits for most things. I'm trying to figure out how people make good-looking apps without graphic design skills. You always hear about some 8 year old or 14 year old who made a successful app. So I assume that even if the required code was relatively basic, the app must have looked good if it was a success. But I find it really unlikely that these kids have advanced PhotoShop skills as well as having learned iOS programming at such a young age. Frankly, the same goes for most independent app developers....as they say, unicorns don't exist. So what's the deal? Can you make a good-looking, market quality app without those skills? What are the limitations?

  • How to debug Android App Eclipse?

    - by user2534694
    Ok. So while this isnt a programming question. I wanted to know how do people debug apps? How do you view log cat, and where these exceptions are thrown etc? And do I need to run the app on the emulator to see all the stuff, or is there a way to view this after running the app on my phone(while not being connected to the computer) Links to plugins and tips would be really helpful, as im gonna start work on my next game, and while the first one works fine, had a lot of problems while debugging.

  • A proper file monitoring tool for Windows with notifications

    - by nevvermind
    Developing in PHP, I'm usually confronted with various log files: apache, web apps, error logs etc. I'm currently using Notepad++ with the option to notify me when a file has changed. But when I need to monitor many files, I end up with too many tabs opened. I've used some of these, but they were lacking some basic stuff (like double clicking on the file to open it; oh, c'mon). What do you guys use for monitoring file changes? I needn't be "modern" or fancy. Just a simple "Hey, this file was changed. Here, click on it to open". (Maybe I'll end up making one myself, but I need to learn some more Java).

  • Free Windows 8 book on programming with html, css and javascript

    Just a heads up from DevFish (http://devfish.net), a free book on writing applications for Windows 8using html, css and javascript by Kraig Brockschmidt . You can find the book here: http://blogs.msdn.com/b/microsoft_press/archive/2012/10/29/free-ebook-programming-windows-8-apps-with-html-css-and-javascript.aspx I have not finished reading this but so far it looks like it will be a great resource if you have any interest in trying the windows 8 javascript programming model. Besides all the aspects of controls, library support and animations the book also talks about how to make your own components in c#, vb or c++.

  • Can we have some "coming soon" text in our app? Will Apple reject it? [closed]

    - by Pedro
    We're getting ready to push our app live. There's some functionality that's not ready yet; it's accessory, not crucial to the user, but it does provide some interesting context. If I have a button with the name of the feature (e.g., "Panoramic Views") and a "COMING SOON" label stuck over it, will Apple reject the submission? What if instead of a button it's just a text label somewhere announcing "Panoramic Views coming soon!"? I've seen some material online saying that "coming soon" is a no-no but all I could find in Apple's guidelines themselves was 2.9, "Apps that are "beta", "demo", "trial", or "test" versions will be rejected". Which is certainly not the case! Thanks in advance, any help greatly appreciated.
