  • Best practices for App Idea ownership and shares

    - by JOG
    I am developing apps on my sparetime. I am the sole developer, and two non-programmer friends of mine provide vision, content, algorithms and ideas. We always agree happily on all the features, todos and prioritizations. But naturally, coding it is the biggest part. When selling, we agree on splitting profit equally, that is 33% each. But version 1.0 naturally does not sell much. And I go on to try to make the app more viral. This includes tons of stuff where the others are of little help. Examples: Adding support for sharing, facebook connect, gameifying, letting users add content, home page, support, maintenance, server services to make it easier for to update content. The list is long. Suddenly I will be doing 100% of a lot of work but only "own" a third of the income. My friends may either "fade out" of the project after 1.0, or they continue to contribute, but with less value and I would rather exchange them for more programmers or graphic designers. The effort they made to version 1.0 is worth a lot to the app and I realize I would have never done it without them. But I am doing all the work in the end. It is hard to negotiate about splitting 90, 5, 5 instead of 33% each, because the idea is still theirs. How to solve this? What are the best practices to regard the ownership of the app? What kind of agreements could I make that make it beneficial and motivational for me to continue developing the app?

  • How can I remove the DRM from books I have purchased for my Kindle? [closed]

    - by Jeremy Banks
    How can I the remove DRM from books I have purchased for my Kindle? A solution that works on Mac OS X and/or Linux would be ideal, but a Windows-only solution is also acceptable. Moral aside: I do not plan to share or pirate books; I am very happy with the Amazon Kindle store and have purchased more books from there since getting my Kindle a month ago than I had in the previous two years. However, I do not feel comfortable keeping them in an encrypted format that only a single company's software will allow me to access. I may also want to convert them into a format for other readers in the future, which is not possible without first removing the DRM.

  • Please help me decide if I should I change jobs [closed]

    - by KindaNewbie
    About me: I am very entrepreneurial and believe I would do well working solo as a consultant and possibly hiring help. I do want to do that at some point. I love to learn and a good challenge. Please help me make this decision! Current job (I am there for about 4 years): Pros: secure job good pay (I guess I am 80 percentile for my level/geographical area) large corporation - main business is not software excellent health insurance for low cost to me, pension, 401k matching, 6 weeks paid time off per year small dev team use of latest technologies (mostly WPF/silverlight) low supervision (I can do personal things all the time) I get to do a lot of moonlighting and my goal was to go solo full-time in a year or so. Cons: small team of non-professional devs 50% of my time I do things I don't enjoy projects are not meaningful to the organization If I left it wouldn't be too hard for them - business would resume as usual. Nobody besides my small team of 3 has any idea about software development whatsoever. Prospect job: Pros: small/agile software company same salary as current job same size dev team but all are very sharp (I would probably be the weakest of the team in the beginning) technology used is outside my comfort zone (latest cool web technolgies such as html5/jquery/...) - I am not a web dev and they know that. ton of learning opportunity Start-up - possibility of stock option/partial ownership of some sort Cons: Small office space - not able to do personal things as often (may be pro) No room for moonlighting less benefits (but salary can compensate for that)

  • Vmware Workstation Development Server on Laptop

    - by Koobz
    I'm running an Ubuntu guest OS on my Windows 7 laptop. Currently, I have it set up for bridged networking. The guest is os is configured for a static ip of 192.168.1.115, which depending on the network I'm connected to, may not be available. When I want to view my development work I hit that up in my web browser. I'm really looking for the following scenario: 1) My guest OS ip address stays constant. 2) I can access my guest os even if I don't have an internet connection, or a lan/router. 3) I can share files with my guest/host. How does one accomplish this using VMware Workstation?

  • Installing a new SQL Server instance fails

    - by Rubio
    I've previously in my setup installed SQL Server Express 2005. Now I've switched to SQL Server Express 2008. I updated the command line parameters to those documented for the latter. If the comp already has SQL Server Express 2008 installed, my installer should create a new instance. The command line parameters are as follows: /ACTION=Install /FEATURES=SQLEngine /QS /INSTANCENAME=ABCD /SECURITYMODE=SQL /SAPWD=CunningPassword The requested instance name does not exist on the target machine. This will end in an error -2068643838. The logs show the following error: "No features were installed during the setup execution. The requested features may already be installed." If I remove the /QS parameter and try to install interactively, I'll get as far as the Feature Selection page. The UI shows three options, Instance Features, Shared Features and Redistributable Features. Whatever I select, clicking Next results in the same error (There are validation errors on this page). Any ideas anyone?

  • Dual monitors, screen resolution, xorg.conf.d

    - by Flase
    I do a lot of RTFM but this one has got me stuck. I have Ubuntu Studio 12.04 Precise Pangolin with XFCE as its default desktop. My old HIS ATI Radeon 9250 graphics card was adding red crud across the screen with the generic driver, but downloading the proprietary "fglrx" driver makes it work cleanly. The trouble is the Catalyst control centre refuses to recognise my old card so I must do some manual configuring to make sure both the DVI and VGA monitors are capable of the correct screen resolution (both 1280x1024) and a dual display. It used to be easier to just edit the existing xorg.conf file and add another resolution and so forth, but now there are automatic xorg.conf.d directories (more than one) with scant documentation. Creating a generic xorg.conf with a terminal command creates every setting imaginable. What I want to do is create the simplest conf file which just tells the system the following: My VGA monitor can do 1280x1024 60Hz The two monitors together may be 2560x1024 width The VGA monitor on the right I might need to specify Xinerama if it's needed Thank you. I don't think I need to bore you with log files, but please ask for further info. Mike

  • All files on automounted NTFS partition are marked as executable

    - by MHC
    I have set up an NTFS partition to automount via fstab: # /etc/fstab: static file system information. # # Use 'blkid' to print the universally unique identifier for a # device; this may be used with UUID= as a more robust way to name devices # that works even if disks are added and removed. See fstab(5). # # <file system> <mount point> <type> <options> <dump> <pass> proc /proc proc nodev,noexec,nosuid 0 0 # / was on /dev/sda7 during installation UUID=e63fa8a2-432f-4749-b9db-dab328807d04 / ext4 errors=remount-ro 0 1 # /boot was on /dev/sda4 during installation UUID=e9ad1bb4-7c1f-4ea9-a6a5-799dfad71c0a /boot ext4 defaults 0 2 # /home was on /dev/sda8 during installation UUID=eda8c755-5448-4de8-b58c-9cb75823c22d /home ext4 defaults 0 2 # swap was on /dev/sda9 during installation UUID=804ff3a7-e5dd-406a-b63c-e8f3c635fbc5 none swap sw 0 0 #Windows-Partition UUID=368CEBC57807FDCD /media/Share ntfs defaults,uid=1000,gid=1000,noexec 0 0 As you can see I have added the noexec bit to the configuration. Why? Because any file I create on or move to the partition is automatically marked as executable. The problem is that there is no way of changing that through nautilus. I cannot uncheck the "Allow executing file as program" option. The noexec option doesn't help, unfortunately. It only prevents nautilus from displaying the "run" or "read" dialog but doesn't change the executable flag. Is there any way I can fix this?

  • How to sum cells depending on the content of a neighbor cell

    - by dannymcc
    I have an Excel document with the following columns; Date | Reference | Amount 23/01/11 | 111111111 | £20.00 25/09/11 | 222222222 | £30.00 11/11/11 | 111111111 | £40.00 01/04/11 | 333333333 | £10.00 31/03/11 | 333333333 | £33.00 20/03/11 | 111111111 | £667.00 21/11/11 | 222222222 | £564.00 I am trying to find a way of summarising the content in the following way; Reference : 111111111 Total: £727 So far the only way I have been able to achieve this is to filter the list by each reference number (manually) and then add a simple SUM formula to the bottom of the list of amounts. Are there any tricks that anyone knows that may speed this up? What I am trying to achieve is a spreadsheet that highlights each reference number that collectively exceeds over £2,000.

  • GNOME session not starting after filesystem corruption

    - by user3215
    I'm running Ubuntu 9.10 desktop edition. Suddenly today /home became corrupted and I was prompted to run fsck manually. I ran fsck -y /home and rebooted the system. The system booted but I got no GUI interface (GNOME session) but a black screen with a user prompt instead. Any tricks here to start my system normally? Any help is greatly appreciated.

  • How to upgrade a single instance's size without downtime

    - by Justin Meltzer
    I'm afraid there may not be a way to do this since we're not load balancing, but I'd like to know if there is any way to upgrade an EC2 EBS backed instance to a larger size without downtime. First of all, we have everything on one instance: both our app and our database (mongodb). This is along the lines i'm thinking: I know you can create snapshots of your EBS and an AMI of your instance. We already have an AMI and we create hourly snapshots. If I spin up a new separate instance of a larger size and then implement (not sure what the right term is here) the snapshots so that our database is up to date, then I could switch the A record of our domain from the old ip address to the new one. However, I'm afraid that after copying over the data from the snapshot, by the time it takes to change the A record and have that change propagate, the data could potentially be stale. Is there a way to prevent this, and is there a better way to do this than I am suggesting?

  • Quad Core host with hyper-threading, how many processors to configure in VirtualBox?

    - by Anthony
    I have a quad-core i7 processor with hyperthreading (8 logical cores), when I configured a virtual machine to use 8 processors, VirtualBox gave me a warning saying that I only have four cores (which is true) and that this may cause a performance issue. But hyper-threading is a hardware feature, so the OS sees 8 cores and it sends instructions to all 8. What if setting it to 4 caused the VM to use 2 cores (4 threads) instead of 4 simultaneous threads (on all 4 cores)? Does the warning I got take into account that my machine has hyper-threading?

  • RAM module randomly stopped working

    - by nhinkle
    My laptop is a Dell Inspiron e1505. It came with 2x512 MB of RAM installed, and about a year and a half ago I decided to upgrade it to 2x1 GB. I bought two 1GB memory modules from newegg and installed them, and all worked fine. Just last night my laptop was working fine; this morning I booted up and there was a BIOS warning saying "amount of system memory has changed". I tried reseating the modules, but that didn't fix it. Then I removed each one individually, and determined that one of the sticks appears to no longer be working. This happened very abruptly - I hadn't noticed any problems which might have been indicative of impending failure. Does anybody have any clue what may have caused this, and if there's any hope of making it work again? The memory only had a 30 day warranty, so I can't RMA it.

  • How can I get a Windows 2008 print server to deploy to child domains?

    - by Tyler Benson
    I am setting up a print server for our company that has a parent domain and 2 child domains. The print server is on the parent domain and I have no problems getting the print server to deploy printers through group policy to users on its own domain. The problem I am having is that it isn't deploying the printers to users that are in it's child domains. Some other info that may help: I am not sharing or listing printers in the directory I have added pushprinterconnections.exe to the group policy login script Does anything come to mind?

  • Added resolution not working after upgrading to 12.04

    - by David
    After upgrading, my screen resolution (added by xrandr comands on the start) did not work like before. Messages appear showing some errors (that i have never had in 11.10). "No se pudo aplicar la configuración almacenada para los monitores"/"Can't apply the stored configuration for the monitors." This script didn't work either. xrandr --newmode "1280x1024_60.00" 109.00 1280 1368 1496 1712 1024 1027 1034 1063 -hsync +vsync xrandr --addmode VGA1 1280x1024_60.00 xrandr --output VGA1 --mode 1280x1024_60.00 I also tryed deleting monitors.xml but, nothing. This only erase the window message. It's been sayd that ##It's a normal buggy and well know problem for Pc's with Intel integrated video cards.## The new version of gnome-settings-daemon stores its configuration information in dconf rather than gconf. I tryed something, but the problem persist. This is what i did. Install the dconf-tools package, and then run dconf-editor. In the tree on the left, navigate org - gnome - settings-daemon - plugins - xrandr. Uncheck the active checkbox. restart your XServer (Ctrl+Alt+Backspace) (It didn't worked out for me, but it may be helpful to someone)

  • What kind of physics to choose for our arcade 3D MMO?

    - by Nick
    We're creating an action MMO using Three.js (WebGL) with an arcadish feel, and implementing physics for it has been a pain in the butt. Our game has a terrain where the character will walk on, and in the future 3D objects (a house, a tree, etc) that will have collisions. In terms of complexity, the physics engine should be like World of Warcraft. We don't need friction, bouncing behaviour or anything more complex like joints, etc. Just gravity. I have managed to implement terrain physics so far by casting a ray downwards, but it does not take into account possible 3D objects. Note that these 3D objects need to have convex collisions, so our artists create a 3D house and the player can walk inside but can't walk through the walls. How do I implement proper collision detection with 3D objects like in World of Warcraft? Do I need an advanced physics engine? I read about Physijs which looks cool, but I fear that it may be overkill to implement that for our game. Also, how does WoW do it? Do they have a separate raycasting system for the terrain? Or do they treat the terrain like any other convex mesh? A screenshot of our game so far:

  • Go/Obj-C style interfaces with ability to extend compiled objects after initial release

    - by Skrylar
    I have a conceptual model for an object system which involves combining Go/Obj-C interfaces/protocols with being able to add virtual methods from any unit, not just the one which defines a class. The idea of this is to allow Ruby-ish open classes so you can take a minimalist approach to library development, and attach on small pieces of functionality as is actually needed by the whole program. Implementation of this involves a table of methods marked virtual in an RTTI table, which system functions are allowed to add to during module initialization. Upon typecasting an object to an interface, a Go-style lookup is done to create a vtable for that particular mapping and pass it off so you can have comparable performance to C/C++. In this case, methods may be added /afterwards/ which were not previously known and these new methods allow newer interfaces to be satisfied; while I like this idea because it seems like it would be very flexible (disregarding the potential for spaghetti code, which can happen with just about any model you use regardless). By wrapping the system calls for binding methods up in a set of clean C-compatible calls, one would also be able to integrate code with shared libraries and retain a decent amount of performance (Go does not do shared linking, and Objective-C does a dynamic lookup on each call.) Is there a valid use-case for this model that would make it worth the extra background plumbing? As much as this Dylan-style extensibility would be nice to have access to, I can't quite bring myself to a use case that would justify the overhead other than "it could make some kinds of code more extensible in future scenarios."

  • Demantra Implementation Tip Windows and Unix or Linux

    - by user702295
    Hello!  Are you implementing using a third party or consulting resources?   Recently we have seen some cases where customers no longer have a windows installation.  After the initial install and configuration, once the instance has gone live, the windows install is either deleted or most likely no longer with the customer as the same was installed on the implementers' laptop to start with. As a result when support comes back requesting the customer to apply a patch and/or upgrade they do not have a windows installation.  This has started happening after Oracle Demantra gave them the option to configure the engine on Unix.  Workaround: It is advisable that the customer keep their Windows installation intact for further patching and/or upgrade.  It is aslo possible that the implementer had installed Demantra on his Windows box and you do not have access to it any more.  It is possible that with the web and engine on Unix, and the silent installer having downloaded all the executable for Business Modeler, to work on the User's client machine, you may no longer need the windows install. I have not tested the above

  • Is there a cheaper alternative to Skype for VoIP to PSTN calls to Vietnam?

    - by Nick Bolton
    My dad uses Skype to make calls to Vietnam PSTN, but finds that the rates are a little on the pricey side. It's probably not relevant, but he's living in Thailand right now. Is there an application similar to Skype, which is cheaper for calling Vietnam? The answer may well be no, since maybe the international telecom peers in Vietnam are just generally expensive... Who knows? While I'm asking, maybe it's worth someone mentioning if there's a cheaper alternative to Skype in general? I'm thinking that maybe not as Skype's pretty cheap anyway, but it's worth mentioning.

  • Disk is apparently in use by the system

    I've just fitted two disks to my home server. I'm trying to format and then raid them but I'm getting a problem that hours of Googling hasn't resolved this.

  • Transmission shutdown script for multiple torrents?

    - by Khurshid Alam
    I have written a shutdown script for transmission. Transmission calls the script after a torrent download finishes. The script runs perfectly on my machine (Ubuntu 11.04 & 12.04). #!/bin/bash sleep 300s # default display on current host DISPLAY=:0.0 # find out if monitor is on. Default timeout can be configured from screensaver/Power configuration. STATUS=`xset -display $DISPLAY -q | grep 'Monitor'` echo $STATUS if [ "$STATUS" == " Monitor is On" ] ### Then check if its still downloading a torrent. Couldn't figure out how.(May be) by monitoring network downstream activity? then notify-send "Downloads Complete" "Exiting transmisssion now" pkill transmission else notify-send "Downloads Complete" "Shutting Down Computer" dbus-send --session --type=method_call --print-reply --dest=org.gnome.SessionManager /org/gnome/SessionManager org.gnome.SessionManager.RequestShutdown fi exit 0 The problem is that when I'm downloading more than one file, when the first one finishes, transmission executes the script. I would like to do that but after all downloads are completed. I want to put a 2nd check ( right after monitor check) if it is still downloading another torrent. Is there any way to do this?

  • Why do I get "Permission denied (publickey)" when trying to SSH from local Ubuntu to a Amazon EC2 se

    I have an instance of an application running in the cloud on Amazon EC2 instance, and I need to connect it from my local Ubuntu. It works fine on one of local ubuntu and also laptop. I got message "Permission denied (publickey)" when trying to access SSH to EC2 on another local Ubuntu. It's so strange to me. I'm thinking some sort of problems with security settings on the Amazon EC2 which has limited IPs access to one instance or certificate may need to regenerate. Does anyone know a solution?

  • How do I check for available "Automatic Updates" via script / cli

    - by Lee
    I asked this on superuser, but I think this may have been a more apropriate place. We are trying to automate server reboots, but one of the "gotchas" we are running into are that they want us to install updates by manually clicking "sure, install updates" during monthly Windows reboots. If I had a way to check to see if updates are in fact waiting, we'd be ok with rebooting automatically via a script and just failing if this is the case. My problem is I can't figure out how to check to see if there are in fact updates waiting to be installed, without logging in. Is there a file or particular service status I can check for? Maybe with Powershell or something similar? The current setting used is "Download updates but do not install automatically"
