  • How do I approach large companies if I have a killer mobile game idea?

    - by Balázs Dávid
    I have an idea for a game that has potential, but I'm not a programmer. How do I tell this to development companies without having my idea stolen? All I want from the company is for somebody to watch a three minute long video presentation about my idea and if they see potential in it then we can talk about the details. I have already sent an e-mail to several big companies that have the expertise needed to code the game, they haven't answered me. Actually the idea is nothing fancy, no 3D, but fun and unique.

  • Google Cloud Messaging (GCM) for turn-based mobile multiplayer server?

    - by Chris
    I'm designing a multiplayer turn-based game for Android (over 3g). I'm thinking the clients will send data to a central server over a socket or http, and receive data via GCM push messaging. I'd like to know if anyone has practical experience with GCM for pushing 'real-time' turn data to game clients. What kind of performance and limitations does it have? I'm also considering using a RESTful approach with GAE or Amazon EC2. Any advice about these approaches is appreciated.

  • disks not ready in array causes mdadm to force initramfs shell

    - by RaidPinata
    Okay, this is starting to get pretty frustrating. I've read most of the other answers on this site that have anything to do with this issue but I'm still not getting anywhere. I have a RAID 6 array with 10 devices and 1 spare. The OS is on a completely separate device. At boot only three of the 10 devices in the raid are available, the others become available later in the boot process. Currently, unless I go through initramfs I can't get the system to boot - it just hangs with a blank screen. When I do boot through recovery (initramfs), I get a message asking if I want to assemble the degraded array. If I say no and then exit initramfs the system boots fine and my array is mounted exactly where I intend it to. Here are the pertinent files as near as I can tell. Ask me if you want to see anything else. # mdadm.conf # # Please refer to mdadm.conf(5) for information about this file. # # by default (built-in), scan all partitions (/proc/partitions) and all # containers for MD superblocks. alternatively, specify devices to scan, using # wildcards if desired. #DEVICE partitions containers # auto-create devices with Debian standard permissions # CREATE owner=root group=disk mode=0660 auto=yes # automatically tag new arrays as belonging to the local system HOMEHOST <system> # instruct the monitoring daemon where to send mail alerts MAILADDR root # definitions of existing MD arrays # This file was auto-generated on Tue, 13 Nov 2012 13:50:41 -0700 # by mkconf $Id$ ARRAY /dev/md0 level=raid6 num-devices=10 metadata=1.2 spares=1 name=Craggenmore:data UUID=37eea980:24df7b7a:f11a1226:afaf53ae Here is 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.

I just can't seem to figure out how to change the boot process so that mdadm waits until the drives are ready to build the array. Everything works just fine if the drives are given enough time to come online. edit: changed title to properly reflect situation

  • Making a mobile app from a board game. Copyright infringement?

    - by Claudio Coelho
    Me and a friend got hooked on a board game and soon realized that we didn't need the board game to play, instead we could play it with pen and paper with extreme ease and satisfaction. The next step was to develop a simple android app to play it. We have been using this to play and it's fun, and we are interested in publishing it, but we are worried eventual copyright issues. The concept of the game - itself very simple, merely a type of trivia game, where each round has different rules - is the same, the name is different as is all the art. Does anybody know if we infringe copyrights if we were to publish it? Thanks

  • How to manage many mobile device users at server side?

    - by Rami
    I built a social Android application in which users can see other users around them by GPS location. At the beginning thing went well as I had low number of users, but now that I have increasing number of users (about 1500 +100 every day) it has revealed a major problem in my design. In my Google App Engine servlet I have static HashMap that holds all the users profiles objects, currently 1500 and this number will increase as more users register. Why I'm doing it? Every user that requests for the users around him compares his GPS with other users and checks if they are in his 10km radius. This happens every five minutes on average. Consequently, I can't get the users from db every time because GAE read/write operation quota will tear me apart. The problem with this design is? As the number of users increases, the Hashmap turns to null every 4-6 hours, I think that this time is getting shorter, but I'm not sure. I'm fixing this by reloading the users from the db every time I detect that it becomes null, but this causes DOS to my users for 30 sec, so I'm looking for better solution. I'm guessing that it happens because the size of the hashmap. Am I right? I have been advised to use a spatial database, but that means that I can't work with GAE any more and it means that I need to build my big server all over again and lose my existing DB. Is there something I can do with the existing tools? Thanks.

  • How do you maintain content size vs. content quality in a mobile application?

    - by PeterK
    I am developing my first Cocos2d iPhone/iPad game that includes quite a few sprites, I would need approximately 80 different. As this is for both normal and HD displays I have 2x of each sprite. I am using TexturePacker to optimize the thing. I would like to ask if there are any rules-of-thumb, tricks, ideas etc. to adjust to in regards to size of content, quality and how you maintain high-quality HD-based graphics due to its size vs. the device memory sizes? Also, is it a good idea to only have one copy of the sprites and scale it using code?

  • Why doesn't max-height hold in Mobile safari in landscape mode?

    - by Mick79
    I am building a small portfolio site for myself and have come across an odd quirk. I have an image inside a container, and to allow for multiple screen sizes, I am setting all dimensions in % rather than pixels. in iphone portrait mode, everything is fine. However in landscape mode, my image bursts out of its container, completely ignoring the max-height:100%; rule that works fine in portrait. code: #centralident{ position:relative; width:50%; height:50%; box-shadow: 0 0 10px black; margin-left:25%; margin-top:13%; } #centralident img{ max-height:100%; }

  • Are HDMI to VGA Adapters Really Device-Specific?

    - by allquixotic
    There are a lot of devices on the market right now (especially mobile devices) with a Micro-HDMI or Mini-HDMI port and no VGA or D-Sub output. Most manufacturers of said devices sell a cable that looks something like this: I have yet to find a cable like this that claims to work on a wide array of devices. In general, these cables claim to work with one specific device only. The way these cables work, I think, is that analog VGA signals are sent from the HDMI port on the device. This should work for devices that have special hardware on the motherboard/GPU capable of driving this. Is it the case that these cables have to be custom designed for each device? Or, is it rather that any device which possesses this special "signaling of analog VGA over the HDMI port" can be made to work with a cable that is physically compatible (i.e. the HDMI end plugs into the device and the VGA end accepts a VGA monitor cable)? Note that I am not looking for a product recommendation, just a conceptual clarification on what exactly these devices are doing. Also, a few remarks: The cables like the one depicted here are not digital to analog converters. I know about these: they are expensive, and they are the ONLY solution if your device only outputs a digital signal and is incapable of driving analog VGA over the HDMI port. The cables like the one depicted here are not straight crossover cables from VGA to HDMI, either. The crossover cables are designed to send a digital HDMI signal over the VGA port's wires; that is, the wire protocol is HDMI (digital) but the physical pinout is the same as VGA, even though nothing analog is happening. Once again, this is not the behavior that, I believe, the devices which I'm talking about in this question are doing. The cabling and devices that this question is about transmit the analog VGA data over the HDMI port (the HDMI port is in the device outputting the data, and the VGA side is the monitor/projector).

  • Server Clustering (Django, Apache, Nginx, Postgres)

    - by system-matrix
    I have a project deployed with django, Apache, Nginx and Postgres. The project has requirement of live data viewable to customers. The projects main points are: 1. Devices in field send data to server(devices are also like website users) after login. 2. There is background import process which imports the uploaded data in postgres. 3. The webusers of the system use this data and can send commands to the devices, which devices read when they login. 4. There are also background analysis routines running on the data. All the above mentioned setup and system is deployed on one amazon EC2 cloud machine. The project currently supports over 600 devices and 400 users. But as the number of devices are increasing with time the performance of the server is going down. We want to extend this project so that it can support more and more devices. My initial thinking is, We will create one more server like current one and divide the devices amongst these to servers. But Again We need a central user and device managment point though django admin. Any Ideas? What are the best possible ways to create a scalable architecture? How can I create a Postgres Cluster and Use it with Django, if possible?

  • How do I reinitialise a failed RAID 5 drive using terminal on Ubuntu Server

    - by Stephen
    I've currently put together a new system and part of that has been creating a software RAID 5 using 'mdadm' in Ubuntu Server. I successfully got to the point where I create the array using: sudo mdadm --create --verbose /dev/md0 --level=5 --raid-devices=4 /dev/sda1 /dev/sdb1 /dev/sdc1 /dev/sdd1 I left it to do its thing overnight then used the following command to check on it: watch cat /proc/mdstat To which the following was returned: Personalities : [linear] [multipath] [raid0] [raid1] [raid6] [raid5] [raid4] [raid10] md0 : active raid5 sdd1[4](S) sdc1[2] sdb1[1] sda1[0](F) 5860535808 blocks super 1.2 level 5, 512k chunk, algorithm 2 [4/2] [_UU_] unused devices: <none> It appears that one has failed (and I'm not too savvy with why another is a spare). So, just to be sure that something else isn't amiss I wanted to try and re-engage the failed drive. Can someone explain how I can do that and what I should do with the spare (if anything). And also how do I know when synchronisation is complete? The tutorial I used to get this far is located here: http://sonniesedge.co.uk/2009/06/13/software-raid-5-on-ubuntu-904/ Many thanks! p.s.

  • Network topology for both direct and routed traffic between two nodes

    - by IndigoFire
    Despite it's small size, this is the most difficult network design problem I've faced. There are three nodes in this network: PC running Windows XP with an internal WiFi adapter.Base station with both WiFi and a Wireless Modem (WiModem)Mobile device with both WiFi and WiModem The modem is a low-bandwidth but high-reliability connection. We'd like to use WiFi for high-bandwidth stuff like file transfers when the mobile is nearby, and the modem for control information. Here's the tricky part: we'd like the wifi traffic to go directly from the mobile to the PC, as rebroadcasting packets on the same WiFi channel takes up double the bandwidth. We can do that with a manual configuration by giving the both the PC and the base station two IP addresses for their WiFi interfaces: one on a subnet shared with the mobile, and one on their own subnet. The routes on the PC are set up so that any traffic going to the mobile via WiModem goes through the secondary IP address so that return traffic from the mobile also goes through the WiModem. Here's what that looks like: PC WiFi 1: 192.168.2.10/24 WiFi 2: 192.168.3.10/24 Default route: 192.168.2.1 Base Station WiFi 1: 192.168.2.1/24 WiFi 2: 192.168.3.1/24 WiModem: 192.168.4.1/24 Mobile WiFi: 192.168.3.20/24 WiModem: 192.168.4.20/24 We'd like to move to having the base station automatically configure the mobile and PC, as the manual setup is problematic when you start having multiple mobiles and PCs. This means that the PC can only have 1 IP address and needs to be treated as being pretty simple. Is it possible to have a setup driven by DHCP on the base station that is efficient with bandwidth?

  • How to configure for multiple gettext domains with babel, pylons, setuptools

    - by ICanHaveSpam
    While trying to internationalize my pylons web and mobile application, 'myapp', Im finding that I would like to keep separate gettext pot files for separate domains. There will be common msgid values for both web and mobile users and there will also be unique msgid values that are only translated for web or mobile users. Im expecting localized msgstrs for mobile users will be different (more terse) than the localized msgstrs for normal web users. The environment is like: the same myapp/controllers will be used for both mobile and web requests. mobile users will have their pages rendered from myapp/templates/mobile normal web users will have their pages rendered from myapp/templates/web What happens by default: I end up with myapp/i18n/myapp.pot and myapp/i18n/*/LC_MESSAGES/myapp.[pm]o files that contain msgid values from controllers and both sets of templates. What Im looking for: to set the gettext domain for the user's session when I decide which templates will render their responses. myapp's msgids from controllers and web template extract into myapp/i18n/web.pot myapp's msgids from controllers and mobile templates extract into myapp/i18n/mobile.pot babel's init_catalog, update_catalog, and compile_catalog runs deal with these separate domains and create separate po and mo localization files. Where Im lost: configuring myapp's setup.cfg and setup.py to deal with separate gettext domains so that I can direct extracted msgid values into a particular pot file based on the path of the python and template files.
