• How can I view and sort after the page count for multiple PDF files in a Windows file explorer?

  - by grunwald2.0

  I unsuccessfully used the "pages" feature in Windows Explorer, as well as in Directory Opus 10 and Free Commander XT (which I installed just for that reason, to try it out) to display the page count of multiple PDFs in a folder. All my PDF's are free to edit, i.e. not write-protected. I don't understand why any PDF reader can display the (correct) page number, but none of the file explorers can? (In the "details" view of course.) The only documents whose page count is displayed are MS Word documents. Do I have to use Adobe Bridge? (I didn't try it.) On a side-note: Did that change in Windows 8? Initial research: Google search was unsuccessful, the only slightly related SE topic I found was "How to count pages in multiple PDF files?".

• License for website article

  - by queueoverflow

  On my personal website, I have some technical ideas and some source code snippets that I share with everybody. To make it clean that everyone can use those snippets as they like, as long as I do not have to provide any warranty, I would like to add a license to the some of the texts. The bigger programs come with GPLv2+, which I think is a reasonable license for free code. Does it make sense to use the MIT License or the GNU Free Documentation License for these texts or should I just go with CC-BY? I am a German citizen, so I heard that the American licenses do not really apply to me at all. If so, that would be another advantage for the Creative Commons Family of License.

• One man software developer product success stories? [on hold]

  - by EugeneKr

  I've got a bad feeling that this question is not appropriate here.. Hopefully you can point me to the right place to ask such a thing (not google though, been there). I want to create my own product, but for some reason have no ideas, so decided to see what people have already done. I would like to start by myself too. I don't mind expanding, but at later stages when it is absolutely necessary. Anyway, to give you an example. There is a guy who created bingo card generation software, then somebody made a wedding planner software and they seem to be doing pretty fine. I would like to know more such cases to draw inspiration from. Do you know such people or maybe you are one of them? Also, if there are places on the net where they dwell, don't hesitate to tell me :) Thanks!

• Ubuntu user expectations from 12.04 and future releases

  - by Rick Green - Turbo

  How much further ahead is 12.10 vs 12.04 in respect to kernel updates and applications? Example: Gimp's newest release is 2.8 which runs equally as well in both 12.04 and 12.10 and probably will in 13.04. What restricts 12.04 from having "the same" look, feel, applications and kernel as 12.10 or the upcoming 13.04? I know that it's more than a name change.....it's whats under the hood that counts. Incrementally upgrading, I feel is safer than radical changes from release to release. Trying to keep a stable desktop and current user experience, how far can I take updating applications before I absolutely have to make a distro upgrade from 12.04LTS

• How do I access an external hard drive plugged into my router?

  - by Shawn

  I am running Ubuntu 11.10 and I own a Netgear N600 Wireless Dual Band Router with a USB port built into it. Naturally, the router came with instructions on how to mount and view this drive with both Windows and Mac, but nothing about Linux. I have an WD Elements 1 TB external HDD that I would like to plug into the router and share across my home network. However, when I plug it in, absolutely nothing happens on my desktop. I checked on two different machines and nothing seems to indicate that the drive has been mounted (or is even seen at all) on either machine. I am fully aware that it may not be possible to do this with a Linux system, but I was hoping someone might have a suggestion. Thanks!

• Is it worth becoming a programmer?

  - by D. Higueras

  Hi everybody. I'm a first year student in CS and I absolutely love programming. Many people have told me it isn't so good once you start working. Some things like bringing your work home(thinking about how to solve problems), working many hours when the timeline reaches an end an so on. I've heard being a system administrator is a lot less stressing job, since you don't have to worry about it at home. So my questions are(for experienced programmers): Is it worth becoming a programmer? Does your job satisfy you enough to overcome these problems? Thanks in advance.

• Will javascript be in the HTML5 standard

  - by Robz

  I'm pretty new to the web development scene, and I just want to be absolutely clear on this because I've read a few conflicting statements. I was under the impression that "html5" is a particular way of constructing xml to represent data for a webpage and "javascript" is a programming language that runs as client-side code in the browser. But left and right I see APIs for javascript (workers, geolocation, local storage, etc.) being referred to as an "html5 technology". Wikipedia says that html5 doesn't have a standard yet, so I can't look it up to see if it somehow mandates stuff about javascript. So will APIs for javascript somehow be apart of the html5 standard? Or has it become a common bad practice to label javascript APIs "html5 technology"?

• AWS EC2: how to compute the cost

  - by EsseTi

  i'm new to AWS, i'm using the free right not and it's terrific. Now, in 1yr the free expires. i went to the website http://aws.amazon.com/ec2/pricing/ where the pricing is but i didn't really get how to compute it. The price are in $ per Hours but i don't think that this means, if i need to have my application running 24h/365d i've to multiplay it for 8760, or do i have? because they write about usage, but how do i compute this value? if i've a website where people in total spend smt like 10 minutes a month and 1 where people spend 750hour a months i pay the same? i can't believe that is the same price. PS:if i've a scheduled task, does it affect the usage?

• Is there a downside of running too many Symfony applications for 1 website?

  - by gentrobot

  Recently I got access to a Symfony 1.2 project which is for just 1 website, but with too many applications. In the past, I have developed websites but with not more than 2 or 3 applications. The cross-application links are achieved by passing the full URL to the 'href' attribute. Since the site is still working absolutely fine, my question is will having too many front controllers (approximately 25-30) hamper the performance of the website? Should I just try to create Cross Application Links or put an additional effort in combining similar applications (I guess almost all of the site's frontend part) into 1 application but different modules ?

• How to open-source a project whose git repository has copyrighted media in the history?

  - by phyzome

  I want to release an audio fingerprinting software project under a free license, but the repository contains copyrighted audio files. The test cases also currently use these files. How do I release the code to the public with maximum version history but without violating copyright? Details: The code is versioned under git. We will collapse it all back into one branch before release. There are 400 MB of audio data. Some files are free-licensed music from e.g. Jamendo, others are MP3s from our personal collections. No matter what approach we take, we'll always keep an immutable copy of the original repo, so as not to destroy project history. Main question: How to handle the public release? Expunge all history of the files in question from the git repository and release the altered repo. (v64 pointed out a way to do this.) Alternatively, take a snapshot of the current state of the code and don't even bother having a public history of the pre-release code. Side question: How could we have avoided this dilemma in the first place, given that sometimes private code or media is needed for the early stages of a project?

• Can I make a business in teaching home users Ubuntu [on hold]

  - by Dorgaldir

  I was thinking about a way to bring Ubuntu to the bigger public, since it has great advantages for people in the lower income class that only use a PC for basic usage. They pay for a windows licence without actually needing windows because 95% of what they do is in a browser and the other 5% is typing a word document or making a simpel Excel sheet. So for these people something like Ubuntu is ideal, they can prolong the life of their old PC or laptop with Ubuntu and thus saving extra money. And as we all know, saving money is not only interesting for the lowest of income but for most of us. But when I talk to people they don't want to use Ubuntu because they know Windows and they don't know this, they'll complain about having to adapt to windows 8 but adapting to Ubuntu seems a bridge too far. But what if someone in the neighborhood gave simple Ubuntu courses. Teaching people about Ubuntu, stuff like: What is an OS What is Ubuntu How do I obtain Ubuntu How do I install Ubuntu How do I set up my email in Ubuntu How do I make a text document in Ubuntu How do I update my facebook wall in Ubuntu ... Simple basic PC usage, but within Ubuntu. But as much as I would like to work for free all day, I can't do this for free for people outside of my social circle. So I was wondering if it is possible to make a business and make money with giving Ubuntu courses, or are their steps to be taken before this is possible. However... Do I need an Ubuntu or Canonical license? Do I need to get a certificate? Do I have to make some kind of deal or contract with Canonical? Just to be clear this is all just an idea in my head at this point, I'm just gathering information. I'm not a teacher at a school, just a programmer that is thinking about options in life. Thanks in advance!

• Windows 8 on iSCSI with LIO target: thin provisioning

  - by LubosD

  I have installed Windows 8.1 on an iSCSI target. This target is provided by Linux LIO and is backed by a sparse file. One of the reasons I created such an installation was thin provisioning. In other words, when I free disk space on Windows, LIO should punch holes into the file, thus free storage space on the Linux server as well. I have checked my kernel's sources and the SCSI UNMAP command is really supported for file-backed targets. On the other hand, deleting files on Windows doesn't lower the amount of space taken by the backing file on Linux (checked with du). Actually, the backing file sometimes grows even more. Some sources on Google say Win8 should support UNMAP/DISCARD on iSCSI, but even in Wireshark I only see ordinary read and write commands when files are being deleted. Any way to fix or troubleshoot it?

• Options for 2D Web/iPhone/Android, with Test Framework

  - by ashes999

  I would like to make a 2D game with one codebase that runs on iPhone, Android, and web (any flavour of web -- HTML5, Flash, Silverlight, etc.) What are my options? I should be able to write my code once, and run it anywhere. I also absolutely need the ability to write unit tests (or write a unit-testing framework) -- I cannot make sizable games without testing. Unity is good, but unity is 3d; even with hacks, the graphical assets will still be 3d. I'm after 2d, not 3d. (If you need a Mac or separate licensing for the Mac part, that's okay.)

• Is it possible to create an "impossible" rooms in games?

  - by qwerty3000

  Forgive me my lack of knowlegde, but for quite a long time I asked myself whether it was possible to create a continous game space that some player could walk inside and so on, that would be absolutely impossible in reality, e.g. you have a very small house that allows you to go around it to see all sides and the full dimensions, and then, when you enter, it is like a giant hall, without any loading screen or (internal) "model change" and so on. I'm no game designer and I never needed to learn 3D-modelling, so I don't know what is possible and what isn't. And is this the same as Is the "impossible object" possible in computer graphics? this? Or is it just the same category, but not exactly the same question? Thanks.

• Bulk Deleting All Messages in a Folder in Microsoft Outlook Web Access [closed]

  - by Cerin

  Possible Duplicate: Multiple delete in Microsoft Outlook Web Access How do you delete all messages in a folder in Outlook, preferrably through Web Access? I left my Outlook account unattended for several days (on vacation) and when I got back I found several folders with over 5k emails, mostly error logging or spam. When I try to open the Outlook client, it just locks up, presumably unable to download that many emails. I can view at most 100 emails at a time, but I can't select all emails to delete or permanently delete them immediately, so manually deleting this many emails is going to take a while. Gmail has a similar feature to select and delete all emails in a folder, and that's free so I figure being a quality non-free product from Microsoft, Outlook should have a similar feature (yes that's sarcasm). I've Googled, but I'm not finding anything. Is this possible?

• Online backup service _with_ filtering (by extension, size and so...)

  - by QyRoN

  Hello, I recentely discovered an ability to backup personal data to online server but I was never surprised when I didn't found a popular service provides filtering capabilities, i.e. all of them they backup all the contents of specific folder. Are there any free options with filtering? To be specific, I need following features: Backup to online server. Automatic but bandwidth-transparent backup, i.e. it will backup my files automatically but won't try to do it if I'm heavily using the computer or internet at the moment. Individual filtering settings for folders, i.e. I want to specify which files to backup in every folder. Some free plan (since I'm not going to use more than 500MB of space).

• How do I configure the mouse to raise and lower windows

  - by user288496

  I've just installed 14.04 and cannot find the congfuration screen to control how mouse clicks are acted on by the window manager, and then optionally passed to the application. I want to set the sane traditional unix behaviour of: - 'focus follows mouse': done. - 'never auto-raise': done. - 'raise when click on border or title': Can't find the option. A middle button click on the tile does lower a window - but traditionally it would also raise the botton window. I can set 'raise on any click' - but that is absolutely hopeless when you are trying to copy text from a lower window.

• Setting up the GDM Theme

  - by Szymoninho

  I'm using Ubuntu 12.04 with Gnome Classic (no effects) and because of the fact that some system options have disappeared with the new system release I've been struggling with this for a while and despite this seems very easy I can't do this :/ - does anyone know how to choose a GDM Theme? I'm quite sure that GDM is now in use on my Ubuntu - I set it up with: sudo dpkg-reconfigure gdm Despite I moved the theme folder to /usr/share/gdm/themes nothing has changed by now, I've logged out and in a couple of times but everytime I get the standard log in window and wallpaper (different from mine). So I'll appreciate any kind of help from anybody, now I have absolutely no idea how to figure it out. Cheers.

• EXC_BAD_ACCESS error when box2d joint is destroyed

Am I destroying the joint in the wrong way? I would really appreciate any help. Thanks

• What can I do in order to inform users of potential errors in my software in order to minimize liability?

  - by phobitor

  I'm an independent software developer that's spent the last few months creating software for viewing and searching map data. The software has some navigation functionality as well (mapping, directions,etc). The eventual goal is to sell it in mobile app markets. I use OpenStreetMap as my data source. I'm concerned about liability for erroneous map data / routing instructions, etc that might result when someone uses the application. There are a lot of stories on the internet where someone gets into an accident or gets stuck or gets lost because of their GPS unit/Google Maps/mapping app... I myself have come across incorrect map data as well in a GPS unit I have in my car. While I try to make my own software as bug free as possible, no software is truly bug free. And moving beyond what I can control, OpenStreetMap data (and street map data in general) is prone to errors as well. What steps can I take to clearly inform the user that results from the software aren't always perfect, and to minimize my liability?

• Too much to learn, dealing with overwhelming varieties of technologies [closed]

  - by zhenka

  I am about to graduate, and I am already working as a web developer in our library IT department. When I look at job postings I am absolutely overwhelmed by the sheer variety of technologies out there. Some companies care about math + algorithms + data structures. Some care about experiences in technology stack XYZ. SQL, css, html, frameworks, javascript, design patterns etc.. etc... etc... At some point I realized I just need to start at mastering a foundation to become employable at a better place and go from there. But the skill-set to get me in the doors varies and I just don't have time to learn everything. How do you deal with this issue? What is the essential stack to become employable? Say in php or ror arena. Perhaps a smarter move would be to move to a technology stack with less variety like .net?

• SQL Cluster install on Hyper V options

  - by Chris W

  I've been reading up on running a SQL Cluster in a Hyper V environment and there seems to be a couple of options: Install guest cluster on 2 VMs that are themselves part of a fail over cluster. Install SQL cluster on 2 VMs but the VMs themselves are not part of an underlying cluster. With option 1, it's little more complex as there's effectively two clusters in play but this adds some flexibility in the sense that I'm free to migrate the VMs between and physical blades in their cluster for physical maintenance without affecting the status of the SQL guest cluster that's running within them. With option 2, the set-up is a bit simpler as there's only 1 cluster in the mix but my VMs are anchored to the physical blades that they're set-up on (I'll ignore the fact I could manually move the VHDs for the purposes of this question). Are there any other factors that I should consider here when deciding which option to go for? I'm free to test out both options and probably will do but if any one has working experience of these set-ups and can offer some input that would be great.
