  • How to publish paid Android apps if you're not from US/UK

    - by Sheikh Aman
    I was pretty excited while creating one of my apps but as it turns out you can't actually sign up for Google Checkout if you don't live either in the USA or in the UK. And since Google Checkout is the only way Android Market will pay you, all my efforts seem to be going in vain. So because I live in India, I can't sell my apps. I tried contacting Google by various means on this, but haven't got any response so far. I tried searching the web as well just to find out that one can't be paid via any other way. I am pretty sure that many people here might have gone through the same problem. How did you solve it? I have a PayPal account and an AdSense account as well. Can they help in any way? And if nothing works out, how am I supposed to be selling my app?

  • How To Deliberately Hide Bugs In Code (for use in a Novel I'm writing) [closed]

    - by Dennis Murphy
    I'm writing a novel in which an evil programmer wants to include subtle errors in his code that are likely to go unnoticed by his supervisor during a code review and unlikely to be caught by a compiler, yet cause damage at possibly random times when the program is executed by an end-user. I only need a couple of examples, which may be exotic but which have to be easily explainable to non-technical readers. Procedural or object-oriented examples would be equally helpful. (It's been a VERY long time since I've written any code.) Thanks for your help.

  • lucid 10.04 LTS => Precise 12.04.1 : upgrade doesn't work

    - by Rastom
    I googled and looked into all unkown issues on ubuntu forums but I can't figure out why a 10.04 LTS server won't detect the last LTS 12.04.1. I guess since 12.04 is a fresh dist, not much is reported for related issues Here is what I did : apt-get update apt-get upgrade apt-get install update-manager-core it was already installed so no update for this package. I checked : /etc/update-manager/release-upgrades [DEFAULT] # Default prompting behavior, valid options: # # never - Never check for a new release. # normal - Check to see if a new release is available. If more than one new # release is found, the release upgrader will attempt to upgrade to # the release that immediately succeeds the currently-running # release. # lts - Check to see if a new LTS release is available. The upgrader # will attempt to upgrade to the first LTS release available after # the currently-running one. Note that this option should not be # used if the currently-running release is not itself an LTS # release, since in that case the upgrader won't be able to # determine if a newer release is available. Prompt=lts I also checked my sourcelist before running apt-get : /etc/apt/sources.list deb http://archive.ubuntu.com/ubuntu/ lucid main restricted universe multiverse deb http://archive.ubuntu.com/ubuntu/ lucid-security main restricted universe multiverse deb http://archive.ubuntu.com/ubuntu/ lucid-updates main restricted universe multiverse deb http://security.ubuntu.com/ubuntu lucid-security main restricted deb-src http://security.ubuntu.com/ubuntu lucid-security main restricted deb http://security.ubuntu.com/ubuntu lucid-security universe deb-src http://security.ubuntu.com/ubuntu lucid-security universe deb http://security.ubuntu.com/ubuntu lucid-security multiverse deb-src http://security.ubuntu.com/ubuntu lucid-security multiverse # deb http://landscape.canonical.com/packages/hardy ./ # deb-src http://landscape.canonical.com/packages/hardy ./ and then following Ubuntu guide for Precise upgrade the command below should work : root@xxxxxxxxx:/etc/apt# do-release-upgrade -d Checking for a new ubuntu release No new release found So am I missing something ? The server was accessing outside through a proxy but I grant direct access to this server to avoid any Internet access problem or redirection but no clue... Any help would be appreciated

  • Ubuntu Lenove OCZ Agility3 - No Grub after install

    - by Michael
    I've tried a dualboot (Win7 + Ubuntu) installation it on a Lenovo E330 with Agility3 240 Gigs... Conclusions: Ubuntu:: Ubuntu 12.04 x86_64 ( 21.06.2012 ) is not able to install grub in a bootable way. Grub will be installed and does update-grub during Installation, recognizes also the Win OS. But after a restart it boots directly to Windows.This is directly connected to the OCZ Agility3. On a good old fashion harddisk (those with the moving parts) Ubuntu is capable to install grub with no problem in a bootable manner. PinguyOS:: PinguyOS 12.04 LTS x86_64 (which is a Ubuntu based distro) is able to handle the Grub installation on OCZ Agility3. However they both use Grub 1.99... What i did:: Installed Windows. Installed Ubuntu. Installed PinguyOS. Grub Updates:: Grub updates are only through Pinguy OS possible, this means you have to edit the Ubuntu Grub entries manually after Kernelupdates on Ubuntu, in the PiguyOS sytem.. What i've already tried: Firmwareupgrade OCZ (livestick, successfull) Install Ubuntu Grub to sda Install Ubuntu Grub to sdc (Ubuntu Partion) Install Ubuntu Grub to /boot update-grub manually after install restore grub any ideas appreciated..

  • I dont know how to run e2fsck or fsck and what are their differences

    - by Salvador
    My Kern.log file advise me to run e2fsck. Aug 30 14:10:11 ubuntu kernel: [ 122.378292] EXT4-fs (sda11): warning: maximal mount count reached, running e2fsck is recommended Aug 30 14:10:11 ubuntu kernel: [ 122.387488] EXT4-fs (sda11): mounted filesystem with ordered data mode. Opts: (null) /dev/sda11 is not mounted within my current OS (Ubuntu 10.04) I have known that e2fsck is a dangerous command when running against the root partition which is at the same hard disk as sda11. I would trust in this solution better than others: Can I run fsck or e2fsck when Linux file system is mounted?

  • Is file permission secured when it transferred from Ubuntu to Windows?

    - by Gaurav_Java
    I am having 9GB text file which is encrypted . This file contains some confidential data . Which is on my system(Ubuntu) and my external HDD (ntfs) . This file get daily updated and then encrypted . But it has to be shared among 2-3 (Windows) person. I defined permission so that no other person can even read this file(chmod 660). It is too large file, so I can't upload it anywhere and it get updated daily basis. But this file travel on Windows OS and Ubuntu also. Even I am having copy of this on my personal computer. Recently it was deleted by some other user over Windows . I just want to know how can I set permission over that file so that it cannot be deleted from any other operating system. If someone delete this file, then I am having data old for couple of days, which is only on my system. I gone through this question it says there is nothing. And from this question I am not able to understand how can I protect it. Can I do anything for preventing this file from being deleted. Then how can I secure this files from getting deleted any suggestion or software or ideas. Maybe I sound silly or this is stupid question. Please don't close it, thanks for any suggestion or solution.

  • Upgrade to 12.04 results to empty Dash, no date & time either on the top panel

    - by Nicolas
    I've upgraded from Ubuntu netbook remix something to 12.04 LTS, and I've got two issues. (Got an Asus eeePc 32bits, Intel 945GME x86/MMX/SSE2 and Intel Atom CPU N270 @ 1.6Ghz x2) Nothing in the Dash. Only the "home" tab, other tabs are missing. No search results whatsoever. Missing elements in the system panel, privacy and date & time. No date & time on the right corner either. I've tried to reset unity with the terminal but the process was a whole mess full of errors. It did show date & time in the system panel (not on the top-right corner) while the process was going on in the terminal. But then it was such a mess (no more icons on the right corner amongst other things), and the process wouldn't complete, so I had to reboot the computer and get Unity as before, still no date & time and privacy.

  • Downsides of using Lubuntu on a good computer [closed]

    - by Yamitatsu
    I have a simple question but yet, hard to find any anwser on it. Are there any downsides of using Lubuntu on a good laptop ? Ihe one I purchased would run Ubuntu really good, but I like the look & feel of Lubuntu. I mainly use it to code or watch movie / listen music, usually a load of applications opened at the same time, 20+ tabs on multiple web browser, etc.. Since Lubuntu is lightweight, i wonder if it lacks of some useful functions or something like that.

  • Running 12.04 as a gateway - resolvconf, dhclient and dnsmasq integration

    - by Adam
    I have a gateway server which is set up originally with Ubuntu desktop 12.04 - perhaps a mistake, I don't know, something to bear in mind. I ripped out network-manager and now want to get resolvconf, dhclient and dnsmasq to play well together. dhclient gets the gateway's eth0 WAN ip address and the ISP DNS name server from the modem. dnsmasq needs to serve dhcp to the rest of the lan on eth1 and acts as a DNS cache both for the lan and for the gateway machine. I also set up iptables as a firewall. Right now, the gateway's /etc/resolv.conf shows only name server = 127.0.0.1 which is correct AFAIK. However I don't think that dhclient is giving dnsmasq the ISP DNS name server nor is dnsmasq picking up the OpenDNS and Google name servers I specified in /etc/network/interfaces - at the moment look-ups, i.e. ping or surfing, don't work unless I manually edit /etc/resolv.conf to put in an upstream name server like 8.8.8.8 So I removed the resolvconf package. Now I'm not getting dhcp on my lan and I'm not able to do DNS look-ups on the host itself - I can surf and ping on the net, but not 127.0.0.1. Where do I go from here? This setup with the config for dhclient and dnsmasq, and the same resolv.conf and hosts files worked on my old debian box.

  • Ubuntu boots up maintenance shell?

    - by Andrew
    Any time I try to start up my computer it goes to a screen titled GNU GRUB version 1.99-12ubuntu5 I can then choose from 5 different options. If I try to just boot Ubuntu, with Linux 3.0.0-20-generic it then goes to a screen saying: mountall: /lib/x86_64-linux-gnu/libc.so.6: version 'GLIBC_2.14' not found (required by /lib/libply.so.2) General error mounting filesystems. A maintenance shell will now be started. CONTROL-D will terminate this shell and reboot the system. root@Brown126:~# Control-D just brings me back to the first screen. And nothing works in recovery mode. How can I fix this?

  • Unable to set my own icon for launcher item in 12.04

    - by Alex K
    I use the Faenza icon collection in Ubuntu 12.04 Unity with no issues. I decided to change my Gimp launcher icon, so I made my own (gimp-ak.png) and added it, and its appropriately sized derivatives, to the Faenza icon folders: /usr/share/icons/Faenza/apps/16/gimp-ak.png /usr/share/icons/Faenza/apps/22/gimp-ak.png /usr/share/icons/Faenza/apps/24/gimp-ak.png /usr/share/icons/Faenza/apps/32/gimp-ak.png /usr/share/icons/Faenza/apps/48/gimp-ak.png /usr/share/icons/Faenza/apps/64/gimp-ak.png /usr/share/icons/Faenza/apps/96/gimp-ak.png /usr/share/icons/Faenza/apps/scalable/gimp-ak.svg I then updated the Icon field in /usr/share/applications/gimp.desktop from "gimp" to "gimp-ak": [Desktop Entry] Version=1.0 Type=Application Name=GIMP Image Editor GenericName=Image Editor Comment=Create images and edit photographs Exec=gimp-2.6 %U TryExec=gimp-2.6 Icon=gimp-ak Terminal=false Categories=Graphics;2DGraphics;RasterGraphics;GTK; X-GNOME-Bugzilla-Bugzilla=GNOME X-GNOME-Bugzilla-Product=GIMP X-GNOME-Bugzilla-Component=General X-GNOME-Bugzilla-Version=2.6.12 X-GNOME-Bugzilla-OtherBinaries=gimp-2.6 StartupNotify=true MimeType=application/postscript;application/pdf;image/bmp;image/g3fax;image/gif;image/x-$ X-Ubuntu-Gettext-Domain=gimp20 After logging off (and even restarting), my custom icon does not show up - Gimp has the default gear icon: Setting the Icon field in gimp.desktop to any other icon in the Faenza collection works fine. What do I need to do to get my custom icon to show up properly?

  • Is it wrong to not support IE or older browsers? [closed]

    - by XToro
    Possible Duplicate: So now Google has said no to old browsers when can the rest of us follow suit? Normally a SO browser but this question doesn't fit there, hopefully it fits here. I just want to ask from web designers' point of view if it's wrong to not care about supporting Internet Explorer or older browsers. The site I'm designing looks great in all browsers except IE9-. There are certain things that IE doesn't support or behave like other browsers; AJAX, JQuery, webkit stuff, some CSS styles, drop-and-drop files from OS etc etc, but it all works great in Safari, FireFox, Chrome etc. Should I be that concerned? I know there are several people that use IE, but it's limitations have just been causing me more work by having to come up with workarounds. From what I've read, many of the issues I've been having should be solved with IE10, but not everybody keeps up to date. I know of several people who are still using IE6! Again, I'm hoping this is the right place to ask a question like this, and if not, please point me to the right stack exchange site instead of just downvoting me. Thanks!

  • Which tool to create a sitemap to plan a future site?

    - by peterpurzelbaum
    I'd like to create a sitemap to plan a future site, and I'm looking for a tool to do it. I'd like to create a list of all articles first. Then a hierachy. Then I'd like to put the articles on several places in the hierachy. I should be able to put one article at different places. I'd like to have the ability to mark the articles in different colors whether they should come into the first version of the website or later.

  • What is the the maximum time for a user to return to Google for the visit to be flagged up as a bounce in GA?

    - by Anonymous
    I know that Google measures bounce rates by how fast a user returns to the results page after clicking-through to a website. Roughly what is the maximum duration of the visit for the user to then return for it to be considered a bounce? i.e. <5 seconds, <30 seconds? I'm mainly interested as it appears a lot of users clicking through my PPC adverts (Adwords) are bouncing, despite my ads having a high quality score and the page's being entirely related to the adverts copy and at as best tied to what I think user's may be searching for from the key phrases I've selected so the high bounce rate (100% on some keywords) seems a bit strange. If a bounce isn't determined by time, but simply whether a user returns to the SERP after visiting my site or not after any amount of time that would make more sense but the average duration of visit for my keywords with a 100% bounce rate in GA is 00:00:00, which suggests a user immediately returned to the SERPs, which again, is odd. Is my GA data being skewed by https or anything like that? Scratching my head here.

  • Is it possible to hide some topics in phpBB forum?

    - by Martin
    I would like to be able to hide some of the topics in a phpBB-based forum temporarily from the users - perhaps with the exception of administrators and moderators. I am using the forum for my students and I have solutions of some problems from exams and tests there - posted either by me or by some of the students. I plan to use the same or very similar problems during the next academic year. So I don't want the students to see them, but I want to make the solutions visible again after the tests; so that I do not have to post solutions to same questions again. Is something like this possible? Is this a standard part of phpBB, or do I need to install some modification(s) for it?

  • Allow a web designer to modify DNS without letting them transfer the domain?

    - by PhilCK
    We are in the process of having a web designer create a new website for us, but I don't want to give access to the control panel for the domain names (and have no way to limit it, it seems), while at the same time I don't want to be the go between guy for editing the settings. Is there a way or a service for me to point the domains at a 3rd party DNS system, that I can then give access for the web designer, without worrying that he can find my personal info or try and transfer my domain out?

  • Sharepoint 2010 as framework for website?

    - by Kenny Bones
    So I'm looking at several solutions for our new website. And we've looked at ExpressionEngine first and foremost. Now, during brainstorming today, one person said "why don't we use Sharepoint 2010 to build the site on?", and it doesn't seem like a horrible idea. I mean, we're based around Office anyway. We use Lync and have an intranet based on Sharepoint 2010 anyway. Does anyone have any thoughts on this? Would it cost more to develop an internet webpage on Sharepoint 2010 opposed to using ExpressionEngine?

  • SEO & Multilingual: would be this a good practise?

    - by Younès
    I am currently making a bilingual website and I'd like to get nice SEO results of course. Here's my idea: The internal links would be composed of the "www" subdomain so that people can share links regardless of their language. Anyway, their language is determined by the HTTP_ACCEPT_LANGUAGE PHP variable. So, they would see http:// www.site.com/mydocument/123 in their adress bar and never see any links like "http:// fr.site.com/mydocument/123" or "http://en.site.com/mydocument/123" The user can always switch the page's language thanks to links in the footer. The switching language link would be : http:// fr.site.com/mydocument/123 , and clicking on it would change his language session and redirects the user to http:// www.site.com/mydocument/123 In case of a crawling bot: I read that if the HTTP_USER_LANGUAGE variable was missing then it's a crawling bot. So, in that case, we set the defaut language as English. Each page, as I mentionned earlier, has a link for another language: On the page: http:// www.site.com/document/1323, the link http:// fr.site.com/document/1323 can be seen by the bot and be crawled. What do you think about this practise ? Would I get good SEO results for each language ?

  • Many Stack Overflow users' pages have no Google PageRank and they are not indexed, why?

    - by Marco Demaio
    If you go to my user page on Stack Overflow and you check it with the Google Toolbar, you can see it has no PageRank at all (this does happen for almost any user page, even people with much higher reputation, the only exceptions seem to be the users in page 1, and some other users they have PR). My user page's Page Rank is not only zero, but not calculated at all. When PR is 0 or less than 1, but calculated the Google bar shows white, but when the PR is not even calculated like in my user page the Google bar shows in grey. I further more discovered that my user page is NOT EVEN INDEXED on Google, simple test is searching on Google for the exact page url: "http://stackoverflow.com/users/260080/marco-demaio" and you will see no result. The question is how can this be??? This is really weird to me because of the following reason: If you search on Google for "Marco Demaio" on Stack Overflow only (you can do this by searching "site:stackoverflow.com Marco Demaio") the search result shows hundreds of 'asking/answering questions' pages where I was 'tagged'!!! Let's check one of these: the 1st one that appears now (shows one of the question I asked). We can be sure this page is indexed in Google because comes out in a search. Moreover, its PR is calculated. It's probably nearly zero. Still, some PR flows there, the PR bar is not grey, but white: The page shown above has got links to my own user page. I checked the source code of the page shown above and the links are not hidden or set with a rel="nofollow", moreover I can't see any meta character excluding the links on the page from being followed. So what's happening? Why Google does not see my user page at all. Did Stack Overflow do something to achieve this? If yes what did they do? Any explanation really appreciates (as always). P.S. obviously I checked also the code of my user page, but I could not find meta tags excluding Google search for the page. P.S. 2 in a desperate adventure I also checked Stack Overflow's robots.txt but it does not seem to exclude user pages. UPDATE 1 following up on some answers, I did some more research. Excluding for a while the PR problem (since PR is not science), and looking only at the user page on Stack Overflow NOT BEING INDEXED problem: pages do not seem to be indexed by Google because of the user reputation, this user for instance has got NOW 200 points less reputation than me and his page is indexed (while mine not). It does not seem even to be connected with months you have been on Stack Overflow, this user (almost my same reputation) has been there for 3 months only and his page is indexed (while mine not and I have been a user for 7 months). It's bizarre! UPDATE February/2011 As of today, the page got indexed by Google at least when you search for "site:stackoverflow.com Marco Demaio" it's the 1st page. The amazing thing is that it has still got NO PageRank at all: Google toolbar states loud and clear "No PageRank information available". It's odd!

  • android game performance regarding timers

    - by iQue
    Im new to the game-dev world and I have a tendancy to over-simplify my code, and sometimes this costs me alot fo memory. Im using a custom TimerTask that looks like this: public class Task extends TimerTask { private MainGamePanel panel; public Task(MainGamePanel panel) { this.panel=panel; } /** * When the timer executes, this code is run. */ public void run() { panel.createEnemies(); } } this task calls this method from my view: public void createEnemies() { Bitmap bmp = BitmapFactory.decodeResource(getResources(), R.drawable.female); if(enemyCounter < 24){ enemies.add(new Enemy(bmp, this)); } enemyCounter++; } Since I call this in the onCreate-method instead of in my views contructor (because My enemies need to get width and height of view). Im wondering if this will work when I have multiple levels in game (start a new intent). And if this kind of timer really is the best way to add a delay between the spawning-time of my enemies performance-wise. adding code for my timer if any1 came here cus they dont understand timers: private Timer timer1 = new Timer(); private long delay1 = 5*1000; // 5 sec delay public void surfaceCreated(SurfaceHolder holder) { timer1.schedule(new Task(this), 0, delay1); //I call my timer and add the delay thread.setRunning(true); thread.start(); }

  • Should we always prefer OpenGL ES version 2 over version 1.x

    - by Shivan Dragon
    OpengGL ES version 2 goes a long way into changing the development paradigm that was established with OpenGL ES 1.x. You have shaders which you can chain together to apply varios effects/transforms to your elements, the projection and transformation matrices work completly different etc. I've seen a lot of online tutorials and blogs that simply say "ditch version 1.x, use version 2, that's the way to go". Even on Android's documentation it sais to "use version 2 as it may prove faster than 1.x". Now, I've also read a book on OpenGL ES (which was rather good, but I'm not gonna mention here because I don't want to give the impression that I'm trying to make hidden publicity). The guy there treated only OpenGL ES 1.x for 80% of the book, and then at the end only listed the differences in version 2 and said something like "if OpenGL ES 1 does what you need, there's no need to switch to version 2, as it's only gonna over complicate your code. Version 2 was changed a lot to facillitate newer, fancier stuff, but if you don't need it, version 1.x is fine". My question is then, is the last statement right? Should I always use Open GL ES version 1.x if I don't need version 2 only stuff? I'd sure like to do that, because I find coding in version 1.x A LOT simpler than version 2 but I'm afraid that my apps might get obsolete faster for using an older version.

  • Can anyone recommend an AI sandbox?

    - by user19433
    I'm passionate person, who has been around AI from a long time [1] but never going in deep enough. Now it's time! I've been really looking for some way to concentrate on AI coding but couldn't succeeded to find an AI environment I can focus on. I just want to use an AI sandbox environment which would let me have tools like: visibility information character controller able to easily define a level, with obstacles of course physics collider management triggers management don't need to be a shiny, eye candy graphical render : this is about pathfinding, tactical reasoning, etc.. I have tried : Unreal Dev Kit : while the new release announce is about C++ coding, this is about external tools and will be released in 2013 Cry Engine : really interesting as AI is presents here but coding with it appears to be an hell: did I got it wrong ? Half Life source, C4, Torque, Dx Studio : either quite old, not very useful or costly these imply to dig in documentation (when provided) to code everything, graphics included. Unity 3D : the most promising platform. While you also need to create your own environment, there are lot of examples. The disadvantage is, in addition to spend time to have this env. working, is the languages choice : C#, Javascript or Boo. C# is not that hard, but this implies you'll allways have to convert papers (I love those from Lars Linden) books codes, or anything you can have in Aigamedev are most often in C++. This is extra work. I've look at "Simple Path", the very good Arong Greenberg work but no source provided and AngryAnt work. AI Sandbox : this seems to be exactly what as AI coder I want to use. I saw some preview but from 2009 we still don't know what it will be about precisely, will it be opensource or free (I strongly doubt), will I be able to buy it? will it really provide me tools I need to focus on AI ? That being said, what is the best environment to be able to focus on AI coding only, is it even possible?

  • Collision detection doesn't work for automated elements in XNA 4.0

    - by NDraskovic
    I have a really weird problem. I made a 3D simulator of an "assembly line" as a part of a college project. Among other things it needs to be able to detect when a box object passes in front of sensor. I tried to solve this by making a model of a laser and checking if the box collides with it. I had some problems with BoundingSpheres of models meshes so I simply create a BoundingSphere and place it in the same place as the model. I organized them into a list of BoundingSpheres called "spheres" and for each model I create one BoundingSphere. All models except the box are static, so the box object has its own BoundingSphere (not a member of the "spheres" list). I also implemented a picking algorithm that I use to start the movement. This is the code that checks for collision: if (spheres.Count != 0) { for (int i = 1; i < spheres.Count; i++) { if (spheres[i].Intersects(PickingRay) != null && Microsoft.Xna.Framework.Input.ButtonState.Pressed == Mouse.GetState().LeftButton) { start = true; break; } if (BoxSphere.Intersects(spheres[i]) && start) { MoveBox(0, false);//The MoveBox function receives the direction (0) and a bool value that dictates whether the box should move or not (false means stop) start = false; break; } if (start /*&& Microsoft.Xna.Framework.Input.ButtonState.Pressed == Mouse.GetState().LeftButton*/ && !BoxSphere.Intersects(spheres[i])) { MoveBox(0, true); break; } } The problem is this: When I use the mouse to move the box (the commented part in the third if condition) the collision works fine (I have another part of code that I removed to simplify my question - it calculates the "address" of the box, and by that number I know that the collision is correct). But when I comment it (like in this example) the box just passes trough the lasers and does not detect the collision (the idea is that the box stops at each laser and the user passes it forth by clicking on the appropriate "switch"). Can you see the problem? Please help, and if you need more informations I will try to give them. Thanks

  • Tweaking AStar to find closest location to unreachable destination

    - by Shivan Dragon
    I've implemented AStar in Java and it works ok for an area with obstacles where the chosen destination is reachable. However, when the destination is unreachable, the calculated "path" is in no way to the closest location (to the unreachable location) but is instead some random path. Is there a feasible way to tweak AStar into finding the path to the closest location to an unreachable destination?
