  • How is a software backdoor implemented?

    - by rdasxy
    The wikipedia article on Limewire says that "LimeWire 5.5.11 and newer have been disabled using a backdoor installed by the company". How are such backdoors implemented? Is it as simple as the the program going out and checking a web service and disabling itself? If it's in fact so simple, it has to be stored somewhere on the user's drive (in a plist, or in the registry for example). It's hard to imagine no one has in fact figured out a way to turn that flag off and use the program.

  • Sync profile/data/software for multiple computers?

    - by ultimatebuster
    Is it possible to sync all the user settings (interface settings, program settings), as well as programs for multiple computers? Data is not as important, though the settings (which is technically data, but not that kind of data, like music, files...) and applications are. Also, it will not sync the drivers. (Example: 1 computer uses bumblebee and the other uses ATI catalyst, and maybe there's different network drivers.. etc.)

  • Best practices for launching a new software version

    - by steve
    I rebuilt a web app to replace a version that we have been using for the last 3-4 years. We have a few thousand clients and a few hundred active users per day. The functionality is basically the same. The new version is a little bit faster with a few enhancement features and there are a lot of behind the scenes changes that the clients will never see. The UI is quite different but ultimately much easier to use and navigate. How should I go about having our clients stop using the old system and start using the new one? I am currently putting together a video that will play on the web site as well as within the app. The video will go through the pages and focus on some key changes. I was also thinking about an intro page that will display once the user logs in and explains some of the features.

  • Ubuntu Software Center and Update Manager fail to open

    - by Giancarlo Palmiotti
    After attempting to install Google Chrome i386 the installation failed. I then proceeded to the AMD64 to see if it was the problem but...... My computer froze and I forced shut down. Now apport has a message saying An Error occurred please run Package Manager to fix the problem E:the package google-chrome-stable needs to be reinstalled but but i cant find an archive on it) This usually means your packages have unmet dependencies. Solution anyone PS:Update manager does not work and I don't have Snyaptic. The file itself failed at the real real end and froze everything but the cursor.

  • What are interesting research questions with regards to open source software development? [closed]

    - by Aron Lindberg
    Imagine you have funding for a team of social scientists to study open source software development for a number of years (long time in software development, I know, but a short time for scientific research). These scientists have competencies to investigate psychological and sociological aspects of open source software development (i.e. how coders think, feel, and behave, along with how communities work or do not work). They are also technically equipped to understand code and coding, have access to all sorts of statistical and machine learning techniques, however their focus is on social aspects of open source software development, not technical. For you, as an open source software developer, what would be the research questions that would be interesting for you to have answered by such a group of scientists?

  • Tools to test softwares against any attacks for programmers ?

    - by berkay
    in these days, i'm interested in software security. As i'm reading papers i see that there are many attacks and researchers are trying to invent new methods for softwares to get more secure systems. this question can be a general including all types of attacks.There are many experienced programmers in SO, i just want to learn what are using to check your code against these attacks ? Is there any tools you use or you don't care ? For example i heard about,static,dynamic code analysis, fuzz testing. SQL injection attacks Cross Site Scripting Bufferoverflow attacks Logic errors Any kind of Malwares Covert Channels ... ... thanks

  • SQL Developer: Why Do You Require Semicolons When Executing SQL in the Worksheet?

    - by thatjeffsmith
    There are many database tools out there that support Oracle database. Oracle SQL Developer just happens to be the one that is produced and shipped by the same folks that bring you the database product. Several other 3rd party tools out there allow you to have a collection of SQL statements in their editor and execute them without requiring a statement delimiter (usually a semicolon.) Let’s look at a quick example: select * from scott.emp select * from hr.employees delete from HR_COPY.BEER where HR_COPY.BEER.STATE like '%West Virginia% In some tools, you can simply place your cursor on say the 2nd statement and ask to execute that statement. The tool assumes that the blank line between it and the next statement, a DELETE, serves as a statement delimiter. This is not bad in and of itself. However, it is very important to understand how your tools work. If you were to try the same trick by running the delete statement, it would empty my entire BEER table instead of just trimming out the breweries from my home state. SQL Developer only executes what you ask it to execute You can paste this same code into SQL Developer and run it without problems and without having to add semicolons to your statements. Highlight what you want executed, and hit Ctrl-Enter If you don’t highlight the text, here’s what you’ll see: See the statement at the cursor vs what SQL Developer actually executed? The parser looks for a query and keeps going until the statement is terminated with a semicolon – UNLESS it’s highlighted, then it assumes you only want to execute what is highlighted. In both cases you are being explicit with what is being sent to the database. Again, there’s not necessarily a ‘right’ or ‘wrong’ debate here. What you need to be aware of is the differences and to learn new workflows if you are moving from other database tools to Oracle SQL Developer. I say, when in doubt, back away from the tool, especially if you’re in production. Oh, and to answer the original question… Because we’re trying to emulate SQL*Plus behavior. You end statements in SQL*Plus with delimiters, and the default delimiter is a semicolon.

  • How can I get my progress reviewed as a solo junior developer

    - by Oliver Hyde
    I am currently working for a 2 person company, as the solo primary developer. My boss gets the clients, mocks up some png design templates and hands them over to me. This system has been working fine and i'm really enjoying it. The types of projects I work on are for small - medium sized businesses and they usually want a CMS system. Developed from scratch i'll build a customised backend for the client to add/edit/remove categories, tags, products etc and then output them to the front end according to the design template handed to me. As time has gone on, the projects have increased in complexity, with shopping cart / ordering features and other common e-commerce type features. Again, this system has been working fine and i'm really enjoying it. My issue is my personal development as a programmer. I spend a lot of my spare time reading programming blogs, checking through stackexchange, reading suggested programming books (currently on 'The Pragmatic Programmer', really good so far), doing brain exercises (lumosity.com and khanacademy math problems), doing lots of physical exercise and other personal development type activities. I can't help but feel though, that I'm missing out on feedback, critique. My boss is great and never holds back on praise in regards to my work, but he unfortunately is either to busy to check my code, or to be honest, I don't think it's one of his specialties and so can't provide feedback. I want to know what i'm doing wrong and what i'm doing right. Should I be putting that much logic in the controller, am I modulating my code enough etc. So what I have done is developed a little 'Family Budgeting' app and tried to do it as cleanly and effectively as I currently know how. What i'm wanting to know is, is there somewhere I can submit this app, and have some seasoned developers provide feedback. It's not just a subsection of my code like 'codereview.stackexchange' appears to require, it's my entire workflow that I want critiqued. I know this is a lot to ask, and I expect the main advice given will be to look for a job within a team, which is certainly something I will look into later down the track, but for now I want to persist with my current employment situation, but just don't want to develop too many bad habits. Let me know if I can provide any further information to help clarify, or if this isn't the right place for this type of question I apologise in advance. Didn't want to use reddit as I felt this community fosters more well thought out responses.

  • Can I distribute a software with the following permission notice

    I've recently written a piece of software (without any other contributors) for a company which I part own.

  • What's wrong with the analogy between software and building construction?

    - by kuosan
    Many people like to think of building software as constructing a building so we have terms like building blocks and architecture. However, lately I've been to a couple of talks and most people say this analogy is wrong especially around the idea of having a non-coding software architect in a project. In my experience, good software architects are those who also write code so they won't design things that only looks good on paper. I've worked with several Architecture Astronauts, who have either limited or outdated experience in programming. These architecture astronauts quite often missed out critical details in their design and cause more harm than good in a project. This makes me wonder what are the differences between constructing a software and a building? How come in the building industry they can have architects who probably never build a house in their life and purely handles design work but not in the software development field?

  • what is a normal developer to pageview ratio?

    - by Anthony Shull
    I work for an e-commerce site that has lately been shedding its workforce. I was hired ten months ago as a UI Developer. At that time we had three other developers. One was the technical lead who had been with the company for 10 years. The other two were server-side developers who had been there for 10 and 3.5 years respectively. In ten months, the technical lead left for a better position, one developer was laid off, and the other very recently left. So, I am now the only developer on staff. We have one DBA and one network administrator. They are currently looking to hire another developer but are not willing to pay enough to hire a senior person. I consider myself a junior developer with two years of experience. I have argued that we need to hire at least one senior developer and another junior developer if we're going to keep our current site operational (not to mention develop new features)...even if that means laying off staff in other departments. Right now we get 6.5 million pageviews per month, and I feel like 3.2 million pageviews per developer must be incredibly abnormal. My question is then: what is a normal developer to pageview ratio? Are there any industry standards or literature on the subject that I can use to argue for more staff?

  • Software for monitoring internal software?

    - by Tyler Eaves
    Is there any good software for monitoring the health of a collection of related software? Requirements are as follows: Web-based, deployable on standard Linux/BSD software. Configurable to support a variety of processes, scheduled at various intervals. Some sort of dashboard interface, for monitoring status, viewing errors, etc. As an example, suppose we have a daily export that's scheduled to run at 6AM each morning. After the export completes, it would POST a status message, saying it had completed, passing in some sort of application key to identify the export. If that status message hadn't come in, by, say, 6:30AM, an e-mail might be sent, that application should go red on the dashboard, etc. Applications should also be able to post error/warning messages. Basically the goal is to be able to monitor all of our internal projects from one system, rather than a multitude of e-mails, log files, etc. I suspect that I'll probably have to end up writing this from scratch, but I just thought I'd ask.

  • Is there any reason to install software as root as opposed to sudo installing software as a sudoer?

    - by Tchalvak
    I'm setting up a new server running Ubuntu Server Edition, and I'm not certain what the difference would be between installing most of the basic software as root, vs installing the basic software as an admin user using sudo apt-get install . For one thing, I'm not sure whether after installing the software as root, I'll need sudo access when running the software as a user (e.g. if I install git as root). On the other hand, if I install software as a user, I could conceive of it not being available to other users that I create in the future. What's the best practice here?

  • Software for scanning installation process?

    - by no name
    I forgot what is the name of the very good software which make some kind of restore point (save registry, and program files folder, etc...) before installing any software. After you install some program (ie "Notepad++") you can easily see what registry data use new installed program, on what location are the file's is stored and many more. The reason that I'm asking for help is that I have to automate some installation of public software, so after installation I need to uninstall it, so i have to delete all junk files. The software is called something like install wizard, or wizard install I forgot. If you have any idea of other application that do same thing , or you know exactly name of that software, or you have some good idea how to solve easy solve many installation and uninstallation, please let me know. Os: win7/xp 64/32

  • Can't install software from Ubuntu software center

    - by Casbar
    I've been experimenting with Ubuntu 10.04(64bit) inside a VirtualBox VM. This isn't my first experience with Linux, but I'm still very much a Linux noob. Whenever I try to install software from the Ubuntu Software Center, the installation gets interrupted and I get a warning that this installation requires untrusted sources. I can install anything I want using apt-get, it's just the gui that doesn't work. I've done research on the issue and taken the following precautions with no result: under software sources Allowed Canonical partners Allowed source code Changed the download source to main server I get no errors when running an apt-get update. Can anyone shed some light on the issue?
