  • Clarity around Advanced Segment defintion

    - by Btibert3
    I am hoping to get some clarity around an advanced segment I created. For context, our website spans multiple domains. For reasons I wont get into, I created an advanced segment that looks for pages containing my subdomain of interest (subdomain.site.com). I want to ensure that my interpretation of this advanced segment is accurate. Simply, it flags all visits to our entire domain that viewed at least one page on my subdomain of interest? If I am off, what does this advanced segment represent? Many thanks in advance!

  • International multi-OS keyboard layout for both coding and surfing?

    - by Nikolai Prokoschenko
    So yes, the problem has been raised in parts multiple times already. Still I'm looking for a keyboard layout that has the following features: Easy on fingers (Dvorak-like layouts welcome) Easy for coding Includes German characters (typing ä with AltGr-p is not ok). Works well with web-browsing (Ctrl-t and Ctrl-w on one hand, left one very much preferred, since that's where my ex-CapsLock, now Ctrl lies) Works well with default Emacs bindings Works on both Windows and Linux (at least easily installable) I've looked at Dvorak and Neo, they both have a "shortcut problem", i.e. web-browsing and most frequent Emacs combinations use both parts of the keyboard. Using right Ctrl is usually not an option, since it'll give me RSI much faster than keeping QWERTY/Z. Funnily enough, mirroring the default Neo layout would probably be enough for me. So, any ideas?

  • Anyone code at a treadmill desk? [closed]

    - by Sequenzia
    have been thinking about getting a treadmill desk for awhile now but I just don't know if it is possible to code at one. I can see doing a normal computer job while walking very slow but I just don't know if you can write code do it. Like a lot of people I could stand to lose weight and I am just not in shape anymore. I sit at my computer for at least 12 hours a day and then I am on my laptop for a few more hours. I need to do something to help my health. I also have been seeing a lot of reports about the long term health issues related to desk jobs. Like this. Before I drop a few hundred dollars on a new desk I am wondering if anyone has tried a treadmill desk and if so which one?

  • How To Run Chrome OS From a USB Drive and Use It On Any Computer

    - by Chris Hoffman
    Google only supports running Chrome OS on Chromebooks, but don’t let that stop you. You can put Chrome OS on a USB drive and boot it on any computer, just as you’d run a Linux distribution from a USB drive. If you just want to test Chrome OS, your best bet is running it in a virtual machine. This ensures that you won’t run into any hardware-related issues. Your computer may not be able to run Chrome OS properly. Note: You’ll need a USB drive with at least 4 GB of space for this. 6 Ways Windows 8 Is More Secure Than Windows 7 HTG Explains: Why It’s Good That Your Computer’s RAM Is Full 10 Awesome Improvements For Desktop Users in Windows 8

  • lighter-weight (semantic) scuttle

    - by hroptatyr
    Before patching scuttle or semanticscuttle I thought I'd ask if anyone knows of a lighter-weight/faster system to tag bookmarks and vote on them? LAMP is fine. Ideally, I should be allowed to interfere with the database directly. My actual problem is I want to administer roughly 80m bookmarks, tag them, vote on them (it's just 10 users accessing the system), but here's the thing: All of those bookmarks will change their descriptions (and title lines) at least once a day. Both systems support the del.icio.us API but my LAMP stack is unable to cope with the load.

  • How can I instruct nautilus to pre-generate thumbnails?

    - by Glutanimate
    I have a large library of PDF documents (papers, lectures, handouts) that I want to be able to quickly navigate through. For that I need thumbnails. At the same time however, I see that the ~/.thumbnails folder is piling up with thumbs I don't really need. Deleting thumbnail junk without removing the important thumbs is impossible. If I were to delete them, I'd have to go to each and every folder with important PDF documents and let the thumbnail cache regenerate. I would love to able to automate this process. Is there any way I can tell nautilus to pre-cache the thumbs for a set of given directories? Note: I did find a set of bash scripts that appear to do this for pictures and videos, but not for any other documents. Maybe someone more experienced with scripting might be able to adjust these for PDF documents or at least point me in the right direction on what I'd have to modify for this to work with PDF documents as well.

  • CMake can not find PythonLibs

    I am trying to build inria Graphite on my ubuntu which is running in a VirtualBox simulator, I follow the instructions, and install the python-dev packages, but when I run cmake , still got an error: CMake Error at /usr/share/cmake-2.8/Modules/FindPackageHandleStandardArgs.cmake:108 (message): Could NOT find PythonLibs (missing: PYTHON_LIBRARIES PYTHON_INCLUDE_DIRS) (Required is at least version "3.2") Call Stack (most recent call first): /usr/share/cmake-2.8/Modules/FindPackageHandleStandardArgs.cmake:315 (_FPHSA_FAILURE_MESSAGE) /usr/share/cmake-2.8/Modules/FindPythonLibs.cmake:208 (FIND_PACKAGE_HANDLE_STANDARD_ARGS) src/packages/OGF/gel_python3/CMakeLists.txt:11 (FIND_PACKAGE) I checked the /usr/lib/ and find tintin@tintin-VirtualBox:/usr/lib$ find . -name "libpython*" ./x86_64-linux-gnu/libpython3.4m.so.1.0 ./x86_64-linux-gnu/libpython2.7.so.1.0 ./x86_64-linux-gnu/libpython3.4m.a ./x86_64-linux-gnu/libpython2.7.a ./x86_64-linux-gnu/libpython3.4m.so ./x86_64-linux-gnu/libpython2.7.so ./x86_64-linux-gnu/libpython2.7.so.1 ./x86_64-linux-gnu/libpython3.4m.so.1 so why cmake can not find the PythonLibs, or how should I deal with this?

  • Developing instincts and "subconscious debugging" [closed]

    - by ggambett
    For some time now (a couple of years, perhaps?) I've noticed something that happens when I'm writing code. I write something with a syntax error, or some other subtle error. I don't really notice it on a conscious level, but I have a weird feeling about what I just wrote. I then try to compile it and I get a warning or error on the line that provoked the feeling. Lately I've been trying to pay attention to these feelings as they happen, and more often than not, I find errors right there. It's like I'm developing a subconscious debugger (or at least subconscious syntax checking ;)) I've heard of people fixing bugs in their sleep (I did a couple of times), but I don't think I've heard this kind of thing. Does it happen to someone else?

  • Microsoft Office 2013 Takes New Approach

    You can check out an article from Computerworld for a good look at the questions and answers about the new software. For instance, you've probably noticed that I'm not giving the full name. That's because Microsoft seems to be using several names. If you go the traditional route and pay the one-time upfront fee for the shrink-wrapped edition, it's Office 2013. There's also a tablet version called Office Home and Student 2013 RT - but that won't include the iPad, or at least not at first. The consumer preview, which I'll be linking to in a minute, is dubbed Office 365 Home Premium. There ...

  • Why Java as a First Language?

    - by dsimcha
    Why is Java so popular as a first language to teach beginners? To me it seems like a terrible choice: It's statically typed. Static typing isn't useful unless you care a lot about either performance or scaling to large projects. It requires tons of boilerplate to get the simplest code up and running. Try explaining "Hello, world" to someone who's never programmed before. It only handles the middle levels of abstraction well and is single-paradigm, thus leaving out a lot of important concepts. You can't program at a very low level (pointers, manual memory management) or a very high level, (metaprogramming, macros) in it. In general, Java's biggest strength (i.e. the reason people use it despite the shortcomings of the language per se) is its libraries and tool support, which is probably the least important attribute for a beginner language. In fact, while useful in the real world these may negatives from a pedagogical perspective as they can discourage learning to write code from scratch.

  • /etc/apt/apt.conf gets cleared every time I change proxy settings under settings->network->Network proxy

    - by Muriuki David
    I use a proxy server settings at work but when i get home, my network connection uses no proxy settings. every time i get home and use the proxy settings under settings-networks-Network Proxy to set to "none", the file /etc/apt/apt.conf gets cleared and the following day in the morning i have to edit the file and type in the command again, or at least copy paste from a backup file. How can i avoid this situation, its tiring, how can i make the proxy settings gui write to this file for apt-get and software center to work when i set proxy under network settings?

  • Proper password handling for login

    - by piers
    I have read a lot about PHP login security recently, but many questions on Stack Overflow regarding security are outdated. I understand bcrypt is one of the best ways of hashing passwords today. However, for my site, I believe sha512 will do very well, at least to begin with. (I mean bcrypt is for bigger sites, sites that require high security, right?) I´m also wonder about salting. Is it necessary for every password to have its own unique salt? Should I have one field for the salt and one for the password in my database table? What would be a decent salt today? Should I join the username together with the password and add a random word/letter/special character combination to it? Thanks for your help!

  • How can I increase the maximum number of simultaneous users to log in to a server?

    - by nixnotwin
    I use ubuntu server 10.04 on a fairly good machine, with 2.40 dual-core processor and 2GB RAM. My users login with ssh or samba. I have setup LDAP with PAM to sync user accounts between unix and samba. When I allowed about 90 users to login over ssh at once the server refused login for many users. I am using dropbear as ssh server. Even samba logins failed for many users. I need to allow at least 100 users to login at once. Is there anyway to do this?

  • Is Adobe Flash 11.2 working with Nvidia hardware again in 12.04?

    - by Oranges
    I installed the newest Nvidia-Linux drivers version number 304.43 on 12.04 installation and all Flash Videos now show me "accelerated video rendering". Previous Nvidia drivers + Adobe Flash only rendered in software, at least since Adobe officially said they turned off "hardware acceleration" for Linux, because of unstable and unsecure drivers. Has this changed? Is hardware acceleration really back? Can anyone verify this as well? The Nvidia driver 304.43 patch notes said: Fixed a bug that caused VDPAU to hang when expanding the YouTube Flash Player. Hardware: Nvidia 8600M GT

  • Some Early Considerations

    - by Chris Massey
    Following on from my previous post, I want to say "thank you" to everyone who has got in touch and got involved – you are pioneers! An update on where we are right now: paper prototypes v1 To be more specific, we’ve picked two of the ideas that seem to have more pros than cons, turned them into Balsamiq mockups, and are getting them fleshed out with realistic content. We’ll initially make these available to the aforementioned pioneers (thank you again), roll in the feedback, and then open up to get more data on what works and what doesn’t. If you’ve got any questions about this (or what we’re working on right now), feel free to ask me in the comments below. I’ve had a few people express an interest in the process we’re going through, and I’m more than happy to share details more frequently as we go along – not least because you, dear reader, will help us stay on target and create something Good. To start with, here’s a quick flashback to bring you all up to speed. A Brief Retrospective As you may already know, we’re creating a new publishing asset specifically focused on providing great content for web developers. We don’t yet know exactly what this thing will look like, or exactly how it will work, but we know we want to create something that is useful different. For my part, I’m seriously excited at the prospect of building a genuinely digital publishing system (as opposed to what most publishing is these days, which is print-style publishing which just happens to be on the web). The main challenge at this point is working out our build-measure-assess loop to speed up our experimental turn-around, and that’ll get better as we run more trials. Of course, there are a few things we’ve been pondering at this early conceptual stage: Do we publishing about heterogeneous technology stacks from day 1, or do we start with ASP.NET (which we’re familiar with) & branch out later? There are challenges with either approach. What publishing "modes" are already being well-handled? For example, the likes of Pluralsight, TekPub, and Treehouse have pretty much nailed video training (debate about price, if you like), and unless we think we can do it faster / better / cheaper (unlikely, for the record), we should leave them to it. Where should we base whatever we create? Should we create a completely new asset under a new name, graft something onto Simple-Talk (like the labs), or just build something directly into Simple-Talk? It sounds trivial, but it does have at least some impact on infrastructure and what how we manage the different types of content we (will) have. Are there any obvious problems or niches that we think could address really well, or should we just throw ideas out and see what readers respond to? What kind of users do we want to provide for? This actually deserves a little bit of unpacking… Why are you here? We currently divide readers into (broadly) the categories: Category 1: I know nothing about X, and I’d like to learn about it. Category 2: I know something about X, but I’d like to learn how to do something specific with it. Category 3: Ah man, I have a problem with X, and I need to fix it now. Now that I think about it, I might also include a 4th class of reader: Category 4: I’m looking for something interesting to engage my brain. These are clearly task-based categorizations, and depending on which task you’re performing when you arrive here, you’re going to need different types of content, or will have specific discovery needs. One of the questions that’s at the back of my mind whenever I consider a new idea is “How many of the categories will this satisfy?” As an example, typical video training is very well suited to categories 1, 2, and 4. StackOverflow is very well suited to category 3, and serves as a sign-posting system to the rest. Clearly it’s not necessary to satisfy every category need to be useful and popular, but being aware of what behavior readers might be exhibiting when they arrive will help us tune our ideas appropriately. < / Flashback > We don’t have clean answers to most of these considerations – they’re things we’re aware of, and each idea we look at is going to be best suited to a different mix of the options I’ve described. Our first experimental loop will be coming full circle in the next few days, so we should start to see how the different possibilities vary between ideas. Free to chime in with questions and suggestions about anything I’ve just brain-dumped, or at any stage as we go along. If you see anything that intrigued or enrages you, or just have an idea you’d like to share, I’d love to hear from you.

  • My Hard Disk Drive is not visible until I use it

    - by Matthew
    So, suddenly something went wrong. At the beggining of my Ubuntu usage it was all right, but from about 2-4 weeks I've got this problem: Whenever I try to reach my HDD, i have to open it first by files explorer. Example: I use text editor. Last file fails to load, so I got to open it manually. It's in bookmarked file. I want to reach my bookmark, which is on HDD(partition for both Ubuntu and Windows , NTFS). If i want to reach my bookmark, i have to go there manually(or at least to HDD, then bookmarks pops up). It also doesn't appear at my side bar until i use it. It kinda looks like it wasn't mounted till then, I don't know. It would be nice if I could deal with it, let's say, automatically. Thanks in advance.

  • Instructions on Installing the FreeNX server on Ubuntu Karmic (9.10) are incorrect

    - by Bob Free
    How does one fix (or report an error) on an 'immutable' help.ubuntu.community wiki page? I am a registered member of the wiki. On http://help.ubuntu.com/community/FreeNX under the section: Installing the FreeNX server on Ubuntu Karmic (9.10) and higher, step #2, bjorn-nostvold erroneously changed on 2013-01-24 "add-apt-repository" to "apt-add-repository". The original "add-apt-repository" is correct - at least on my Karmic (9.10) version of Ubuntu. By the number of confused people I've found via google search, this seems to be throwing off a lot of people, myself included.

  • Why does the Git community seem to ignore side-by-side diffs

    - by Kyle Heironimus
    I used to use Windows, SVN, Tortoise SVN, and Beyond Compare. It was a great combination for doing code reviews. Now I use OSX and Git. I've managed to kludge together a bash script along with Gitx and DiffMerge to come up with a barely acceptable solution. I've muddled along with this setup, and similar ones, for over a year. I've also tried using the Github diff viewer and the Gitx diff viewer, so it's not like I've not given them a chance. There are so many smart people doing great stuff with Git. Why not the side-by-side diff with the option of seeing the entire file? With people who have used both, I've never heard of anyone that likes the single +/- view better, at least for more than a quick check.

  • Installing 12.10 messed up Xorg

    - by Ghost
    So I finally decided to upgrade from 12.04 and now my ubuntu install has been rendered unusable. I'm getting the "no screens detected" error from xorg in the console, and no mattr how many times I reinstall it xorg keeps throwing the same errors. I already had to do a bunch of hacks like nomodeset just to get to the console, else I would get an infinite tabulator after the purple boot screen. The machine has a 4200HD IGP, I even tried installing fglrx legacy (4xxx series and below are not supported in regular fglrx anymore) which was a subpar driver in 12.04 but in hopes that the machine would at least work, but nope, nothing at all. Anyone had the same problem? how do I fix it? EDIT: just wanted to add that I upgraded to 13.04 and it didn't solve anything, in fact it might have broken things even further.

  • Why do consoles have so little memory compared to classic computers?

    - by jokoon
    I remember the Playstation having 2MB ram and 1MB graphic memory. The Playstation 3 now has only 256MB ram and 256MB graphic memory, and I'm sure that the day the console was released, even laptop's "standard" capacity was at least 1GB. So why do they put so little memory in their machines, while developers would benefit a lot by having more ? Or is the memory that much faster than desktops and thus more expensive ? Or is it not that much worth it for developers ? What are the Sony/XBox/Nintendo engineers thinking that seems to be the same reason ?

  • InputLayout handling

    - by Kikaimaru
    Where are you supposed to store InputLayout? Suppose i have some basic structure like. class Mesh { List<MeshPart> MeshParts } class MeshPart { Effect Effect; VertexBufferBinding VertexBuffer; ... } Where should I store input layout? It's a connection between vertex buffer and specific pass, i can live with just 1 pass but I still have diffferent techniques so i need at least an array with some connection to effecttechniques, but I would appriciate something not crazy like dictionary. I could also create wrapper for Effect and EffectTechnique, but there must be some normal solution.

  • how to get started with a game engine [closed]

    - by user19343
    I'm a 3rd year Computer Science student and I would like to get started with building a game engine or at least tinkering with making one. I am curious if there are any good resources to use to get started. I get the idea behind different pieces in the engine, but I'm not really sure about how they fit together. Is there anything out there to help teach me the skeleton of a game engine? So far I've been playing with the idea of a game engine that uses modules built in a circular linked list so that each can do it's computing and then pass move to the next piece of the engine to work.

  • Application menu only on maximised windows?

    - by Echogene
    I know that there is a way to disable global menu. I don't quite want this as I quite like (at least one thing about) global menu. I would like to know if there is a way of disabling global menu for non-maximised windows. Thus I ask: is this possible and if so, how is it done?To me, the menu bar/global menu should be visually a part of the window since it is a part of the program and the window is meant to encapsulate the program. Global menu is only visually a part of a window when the window is maximised and merged with the top bar. I don't like bits of my windows floating all around the screen. You wouldn't drive a car when the driver's seat is on the roof of your house.

  • Naming conventions for newtype deconstructors (destructors?)

    - by Petr Pudlák
    Looking into Haskell's standard library we can see: newtype StateT s m a = StateT { runStateT :: s -> m (a, s) } newtype WrappedMonad m a = WrapMonad { unwrapMonad :: m a } newtype Sum a = Sum { getSum :: a } Apparently, there (at least) 3 different prefixes used to unwrap a value inside a newtype: un-, run- and get-. (Moreover run- and get- capitalizes the next letter while un- doesn't.) This seems confusing. Are there any reasons for that, or is that just a historical thing? If I design my own newtype, what prefix should I use and why?

  • Advanced subversion techniques, what am I missing?

    - by Derek Adair
    I started using SVN about 9 months ago and it's been a game changer to say the least. Although, I feel I'm still a bit lost. I feel like there is a lot more I need to take advantage of to really step up my application development. For example I would like to be able to quarantine any volatile/major changes into some kind of 'sub-repository' or something. I'm finding that major changes are impeding minor bug fixes that are quite urgent. How can I push one simple update without pushing incomplete or broken code?
