  • Learning the nuances of a language (C++)

    - by prelic
    So I'm a recent college graduate, and I really enjoy working in C++; I worked with it a lot in school, and would like to pursue a career writing in C or C++. The problem I'm having is that I'm trying to learn the nuances of C++. I'm not talking about the basics, or even advanced concepts like templates, namespaces, etc. I'm talking about the real nitty-gritty stuff like undefined behavior and stuff like that. When I'm interviewing, and they put a bizarre piece of C++ code in front of me, and ask me what the output will be, I want to be able to nail those questions. Obviously experience is a great way to learn, but when I write code for practice, I [obviously] know what it does. Reading open-source projects have been good practice, but I find that there tends to be an enormous learning curve just understanding the organization of the code (because the projects tend to be large). So basically what I'm asking is, what should I do now?

  • Jaroslav Tulach's Report on NetBeans at OSGiCon

    - by Geertjan
    The latest NetBeans Podcast was recorded over the last few weeks and released yesterday. Aside from the NetBeans news items and interviews (interesting stuff about Joel Murach's new Java book using NetBeans, as well as the new developments in the NetBeans Groovy editor), there is, as always an "API Design Tip" of the podcast. That's really worth listening to, always of course, but especially this time because here Jaroslav Tulach talks at some length about his recent trip to OSGiCon, as well as the history and status of OSGi support in NetBeans IDE. Start listening from just before the 30th minute (i.e., the final segment) if you're interested in this particular topic: https://blogs.oracle.com/nbpodcast/entry/netbeans_podcast_60 For example, hear about how JDeveloper got faster by switching from Equinox to Netbinox. And... will Eclipse find itself on the same OSGi container too?

  • how to launch grub menu for ubuntu guests in virtualbox?

    - by Ubuntuser
    I have ubuntu 12.04 alpha installed in virtualbox. When the virtual machine is started, it boots directly to the login screen without showing the grub menu. How can I get the grub menu to show up on start? Please note: the graphics is broken after recent updates, so i cannot login and make the changes. it is stuck at the screen "Ubuntu is running on low graphics mode" and the mouse and other keys do not work.

  • What standard superseded 830-1998?

    - by user1564158
    I have been looking into how to document software projects more formally, and I have learned about IEEE 830-1998: Recommended Practice for Software Requirements Specifications. However, as you can see from that link, it has been superseded. I know that 830-1998, and probably even 830-1993, are probably just fine for use. However, if nothing else, I would like to know what standard has superseded it. In this case it may not matter, but if other standards are superseded for more technical things, I think it would be a good idea to link somewhere what standard superseded another (if it is not another one in the same line (830, in this case)). It is worth mentioning that: The most recent standard when searching for "Software Requirements Specifications" or "Software Requirements" on the IEEE Standards Association website is 830-1993, The 2004 (current) version of SWEBOK references 830-1993 (paragraph 2.5), The document's Wikipedia article doesn't mention that the standard was superseded. TLDR: How do you find what standard superseded another, and which one took 830-1998's place?

  • Did Microsoft Add Wiretapping Capability to Skype?

    Ryan Gallagher, writing for Slate, put two and two together from a lot of no comments. He noted that back in 2007, German police forces said that they couldn't tap into Skype calls because of of its strong encryption and complicated peer-to-peer network connections; in fact, Skype bluntly stated at the time that, due to its encryption and architecture techniques, it couldn't conduct wiretaps. But that may have changed. Gallagher cited a Forbes article that claims the hacker community is talking about recent changes to Skype's architecture and whether they will allow users to be wiretapped. ...

  • Uninstall Ubuntu

    - by Geordie Dave
    So recently I downloaded the most recent ubuntu iso for installation alongside my Windows 8.1. Everything went really smoothly with no errors or hiccups during installation. The only thing is I've decided that I just wanna go back to using Windows 8.1. I haven't a clue how to uninstall ubuntu now. I was going to use the windows installer but there wasn't one available, however fund this latest iso which provided a much improved installer which as I said made things go a lot better. Has anyone any idea how to uninstall it as I tried the DVD I burnt the iso to and all it gives me the option of is reinstalling ubuntu, there is no option to uninstall once I've installed. Any ideas anyone?

    I am running ubuntu 10.04 64bit on a macbook pro, using the nvidia-drivers version 260.19.29. As of a recent kernel update, all the semi-transparent parts of my theme show as full white. This means: no gradients on scrollbars and buttons, 'inverted' dividers in context menu's, full white gnome-do panel etc. Does anyone know what causes this and how I can fix it? Screenshot examples below. Scrollbars: Gnome-do: 'inverted' dividers in the context menu: (Last two links are not links due to not having sufficient points)

  • OpenJDK In The News: Oracle Outlines Roadmap for Java SE and JavaFX at JavaOne 2012

    - by $utils.escapeXML($entry.author)
    The OpenJDK Community continues to host the development of the reference implementation of Java SE 8. Weekly developer preview builds of JDK 8 continue to be available from jdk8.java.net.OpenJDK continues to thrive with contributions from Oracle, as well as other companies, researchers and individuals.The OpenJDK Web Site Terms of Use was recently updated to allow work on Java Specification Requests (JSRs) for Java SE to take place in the OpenJDK Community, alongside their corresponding reference implementations, so that specification leads can satisfy the new transparency requirements of the Java Community Process (JCP 2.8).“The recent decision by the Java SE 8 Expert Group to defer modularity to Java SE 9 will allow us to focus on the highly-anticipated Project Lambda, the Nashorn JavaScript engine, the new Date/Time API, and Type Annotations, along with numerous other performance, simplification, and usability enhancements,” said Georges Saab, vice president, Software Development, Java Platform Group at Oracle. “We are continuing to increase our communication and transparency by developing the reference implementation and the Oracle-led JSRs in the OpenJDK community.”Quotes taken from the 14th press release from Oracle mentioning OpenJDK, titled "Oracle Outlines Roadmap for Java SE and JavaFX at JavaOne 2012".

  • Banshee keeps copying the same music files to my portable player over and over

    - by Dave M G
    I have Banshee 2.6.0, and I connect my Android phone by USB to sync my music collection of about 1500 songs. For the most part, it works reliably. However, on every sync, it deletes, and then recopies the same 62 songs each time. After that, everything works, and the sync completes successfully. As far as I can tell, these 62 songs are mostly recent additions to my collection, but not all of them, and I can't see any other commonality of significance. This is only a problem because the transfer speed when working within Banshee is quite slow, so this is eating up time. Sometimes I need to make a transfer and go, but I can't, because I'll have to wait for progress bars take their sweet time. I have tried to completely clear out the music files on the phone and resync. I have tried rescanning the music collection. What do I do to fix this irritation?

  • How Can I Upgrade to 11.10 from the Command Line?

    - by nmagerko
    I am trying to upgrade my 11.04 Ubuntu operating system to 11.10, as the current system is not the most recent. However, I cannot use the GUI to upgrade - as from past experience I have learned this - because my graphics hardware only works on 10.04 to 11.04 (non-inclusive) and from 11.10+. So once I can get to 11.10, I should be just fine. Because of this, I need to find a way to upgrade the OS from the command line. Can this be done? Thanks for any and all help.

  • Removal of the JDBC-ODBC Bridge from Java SE 8 JDK

    - by user12629431
    Starting with Java SE 8, the JDBC-ODBC Bridge will no longer be included with the JDK. The JDBC-ODBC Bridge has always been considered transitional and a non-supported product[1] that was only provided with select JDK bundles and not included with the JRE. The JDBC-ODBC bridge provides limited support for JDBC 2.0 and does not support more recent versions of the JDBC specification. I would recommend that you use a JDBC driver provided by the vendor of your database or a commercial JDBC Driver instead of the JDBC-ODBC Bridge. [1]http://docs.oracle.com/javase/7/docs/technotes/guides/jdbc/bridge.html.

  • How do I create a LiveUSB that lets me install any Ubuntu version?

    - by Dariopnc
    What I'd like to do: have Ubuntu installed on a USB drive and from there install any ubuntu version on a hdd. This is kinda different from using usb-creator because I'd like to have a persistent ubuntu install on the USB drive and not upgrade it every 6 months. From there I'd like to be able to install the most recent ubuntu version. I think it's just a matter of configuring ubiquity, but don't know if this is the case and how exactly do this. EDIT: Let's clarify the persistent thing: suppose I have my USB with ubuntu precise on it suppose quantal is out in the wild suppose that I want to install quantal on the hdd of a computer suppose that I want/can use only the USB drive with precise on it I should erase/upgrade precise on the USB drive to quantal and then install it on the hard drive I don't want to touch my ubuntu install on the USB drive, I'd like to be able to install the newer ubuntu version (quantal) on a hdd from another one (precise) on a USB drive I'd better avoid upgrading the installation on the hdd Hope this helps

  • Software Center doesn't ask for a password anymore

    - by Jeff
    So, out of the blue, software-center stopped asking me for a password. It just runs, and then turns grey. Works fine as root, or with sudo. While investigating, I found out about polkit (new to me), and looked at the policies, which seem fine. Looking under localauthority, however, showed that while the sub-directories (10-, 20-, 30-, 50-, 90-) are there, there aren't any files under those. Is that my problem? Should there be a file in the 50-local.d? Or am I still looking in the wrong place for my problem? I looked for similar questions and looked at the answers, but they don't really help any. One other thing, I'm not sure it's related but seemed to happen about the same time: The Dash Home only shows items for recent files and downloads. Nothing anywhere else anymore.

  • What should you include in a development approach document?

    - by Liggy
    I'm in the middle of co-producing a "development approach" document for off-shore resources as they ramp up onto our project. The most recent (similar) document our company has used is over 80 pages, and that does not include coding standards/conventions documents. My concern is that this document will not be consumable and will therefore fail. What should be in a development approach document? Are there any decent guidelines on this topic? EDIT: The development approach document should detail the practices and techniques that will be used by software developers while software is designed, built, and tested.

  • Can someone help me remove/fix ubuntu?

    - by user286152
    I'm very new to ubuntu for starters. Whenever I turn my computer on, it opens to the GNU Grub terminal. It says it supports minimal Bash-Like line editing (I have no idea what this means). To work-around this, I used "exit -ubuntu", this then takes me to a separate page which I selected the Windows Boot Manager and click on the Windows 8.1 icon which makes my Windows 8 load normally. If I click on the other icon, being the ubuntu one, I get put back at the GNU Grub terminal and thats it. If someone could help me either remove ubuntu or repair it so that I can load it again, I would appreciate it. I had installed the most recent ubuntu version. Any other required information to assist I can provide. Thank you.

  • How to choose a language, when taking in account the community it includes?

    - by Rick Rhodes
    I was reading the following article: Great Hackers The following part grabbed my attention: "When you choose a language, you're also choosing a community. The programmers you'll be able to hire to work on a Java project won't be as smart as the ones you could get to work on a project written in Python. And the quality of your hackers probably matters more than the language you choose. Though, frankly, the fact that good hackers prefer Python to Java should tell you something about the relative merits of those languages." I would like to apply his advice on a commercial web application I am building (I am a strong believer in culture and community), yet this article was written in 2004, and python has increased in popularity in the recent years. How can I decided a language when taking in consideration its community, rather than the popularity? Any recommendations? Is there any language community that show dedication and passion for developing, rather than learning a language to get a Job and a paycheck?

  • Backup and the evil RETAINDAYS option

    - by TiborKaraszi
    "So what bad has this option done?", you probably as yourself. Well, not much, but I find it evil because it confuses people, especially those new to SQL Server. I have many times seen people specifying something like 3, and expect SQL Server to keep the three most recent backups in the backup file and overwrite everything which is older than that. Well, that is not what the option does. But before we go into details, let's look at an example backup command which is using this option: BACKUP DATABASE...(read more)
