  • Do I need to change the package name for the free version of my app?

    - by teedyay
    I have an application that I'm going to publish to the Android market. I'm planning on releasing a paid-for version and a free version with restricted feature set. During development I've ensured I can turn features on and off by setting a few constant values, so I only have one codebase. However, now I come to release I'm not clear if I need to make a copy of the app with a different package name for the free version. The documentation on how the market works say updates will only be recognised if they have the same package name and are signed with the same key. Does this mean it's OK to release two applications with the same package name but signed with different keys, or will this break something? Or is it just bad practice?

  • Is there a browser independet bookmarktool supporting tags, date and free comments?

    - by bernd_k
    I am looking for a tool, which helps me to organize my personal bookmarks. I want to be able to assign tags and free comments to a bookmark. I want to search my bookmarks by tags date of bookmarking pattern in title pattern in url It would be nice to be web based to enable sharing my bookmarks between different machines. But for it would be OK, if it works on a single machine as long as it has some import/export way to transfer the links to a new machine replacing the old. As browsers I'm using Firefox and ChromePlus. It would be nice, if the solution works with both browsers. With free comments, I mean additional remarks stored for a bookmark, which is not essential for searching.

  • Is there any free, open source php CMS\framework for described case?

    - by Ole Jak
    I want that cms\framework to create me tables like "Users" "Cameras" and so on and declare classes and simple default methods for them (like paged sql relults and so on). I mean I say to it: I want Users to have ID, SpecialNumber and Name Flilds. and I want to get from it class for table generation (to call it once) and class containing methods such as Search by ID, SpecialNumber and Name, Create User, Delit User and so on functions. Is there any framework/cms like this for working with CODE not ui's and so on... so to say PHP generator or something... The result should be as that framework free as possible. So Is there any free, open source php CMS\framework for described case?

  • Free icons for mobile applications. Where?

    - by Geltrude
    I know that in the sdk folders I can find some (not very well grouped, imho) icon. But, there is a site online specialized that let you download free icons useful for mobile app? Ie world flags, up, down... save, revert..., next..., play, stop..., etc. It would be more appriciated also if you can find these sets in many different colors, and in 2 or 3 sizes (32x32, 64x64, etc.). Have a nice day (ot. Especially my mom - her 62 birthday :-) Edit: those are all good sites, but to green-check the answer I need a small set with the common icons (I think moreabout 50-70 icons), in many different colors and in 2 or 3 different sizes (for lo-mid-hi definition devices). - If a so done site exists for free :-)

  • PDF to HTML - batch converter - most reliable and accurate free AND paid for software?

    - by therobyouknow
    I'm look for either a free or paid-for (about 50$/40pounds) BATCH PDF to HTML converter to convert several PDF files at once. Needs to be able to handle vectored and bitmap images within the file, outputting both as jpegs referenced by the html pages. I've tried iorigsoft paid-for PDF to HTML - problems it seems to hang or just go idle, and the stuff it actually converts have broken links - the wrong name is used for constituent chapters as html. Also tried application from intrapdf.com but this crashes near the beginning of the conversion, consitently. Update: intrapdf works on my Windows XP machine but not on my Windows 7 machine. The only glitch is with the framed index contents html - the graphics in the page do not display in the page in the frame - but if you open the frame only in a new tab then you can see them. That might be a browser glitch in chrome only. This solution is good enough for me - given that I've already spent the money (I had spent before I asked) but I can't accept my own answer as this does not work on Windows 7. Looked at opensource tools but they look equally flakey or use old PDF versions. Need it on Windows 7 32bit home. Thoughts?

  • Is there any free software to check for issues with a DVD drive?

    - by AgentConundrum
    I don't usually play movies on my laptop (prefer the standalone with the tv), but I tried to watch one the other night, and noticed playback was really choppy and had audio artifacts in places. I thought it could be related to memory issues so I rebooted and tried again, but the results were the same. I considered that it could be an issue with the disc, so I tried to clean it but again there was no change. I don't think the problem is with the disc, because I tried another disc and it also had the same problem. I don't think I've ever watched the second disc since I've had it, so it should have been safe in its jewel case. Also, there were no issues when I watched an episode off the first disc in my standalone player. What I'm wondering is: are there are any (free) utilities that can check for issues with the drive itself? I looked around but most of the software I found focuses on integrity checks for the disc, not the drive. I have had issues with this laptop recently (had to replace the keyboard when the cat damaged it while I was cleaning dust out and the machine was ripped apart, also replaced part of the chassis after I cracked it when I tried to open it not knowing a screw was still in it) so I may have just replaced the drive incorrectly. I'm going to check on this while I await an answer to this question. Thanks.

  • Is there a free PDF printer / distiller that creates signable documents?

    - by Coderer
    I've used various methods (mentioned elsewhere on this site) to create PDFs, using a printer driver or converting from PostScript, etc. The common problem is that if I open any of the output files in the newer versions of Adobe Reader, there's an option to "Place Signature" but it's greyed out, or gives an error message that the feature has been disabled for this document. As far as I can tell, there's an option set somewhere in the document metadata that tells Reader "allow the user to sign this document", or don't. None of the free/open source tools that have been been linked to in other SU posts have had this listed as an option (though to be fair I haven't actually downloaded and tried all of them). Is there a tool that does this? Can I just poke a bit with a hex editor somewhere to turn on this functionality? I can sometimes get access to Acrobat Professional to turn on this option, but doing it for every desired case would be more work than I care to do. The current workaround for single-page documents is: Print the document to PDF (possibly via postscript) Open a single-page blank PDF with the "signable" bit turned on in Reader create a custom "stamp" using the Reader markup tools, by importing the printed-to document "stamp" an image of the printed document on the blank page, hoping to get it centered about right place a signature over the document-but-not-really you just stamped This obviously does not scale well at all. It would be much better if I could: Print the document to PDF Drag the document to a simple shortcut / tool / whatever Open the document in Reader Place a signature in the document ETA: Sorry, maybe I should have been clearer -- I'm talking about the certificate-based digital signing available in Adobe Reader, not adding a virtual ink signature. Also, any solution really would have to be available offline.

  • Has anyone had luck running 802.1x over ethernet using the stock Windows or other free supplicant?

    - by maxxpower
    I just wanted to see if anyone else has had luck implementing 802.1x over ethernet. So here's my basic setup. Switch sends out 3 eapol messages spaced out 5 seconds apart. if there's no response the machine gets put on a guest vlan with restricted access. If the machine is properly configured it will authenticate and be placed into a secure vlan. About 10% of my windows xp users are getting self assigned 169 addresses. I've used the Odyssey Access Client and it worked without a hitch. I'm using the setting to automatically use the users windows login to authenticate, but it's workign on 90% of the machines so I don't think that's the issue. Checking the logs on the dc it seems that the machines are trying to authenticate with computer credentials even though they are configured not to. I'm running Juniper switches with IAS for radius. I have radius configured for PEAP and MSvhapv2. Macs and linux boxes seem to have no issues authenticating. One last thing to add If I unplugging the ethernet cable and plug it back in usually resolves the issue, but I'd hardly call that acceptable for production. Kinda long winded and specific for a discussion, but just want to see if anyone else has had similar issues or experiences, or if anyone knows of a free XP supplicant that actually works with 802.1x over ethernet.

  • How can I store logs and meet compliance requirements for free?

    - by Martin
    I am trying to keep long-term logs of an app in such a way, that it could plausibly demonstrated to third parties/court that the application has processed certain data at a given time. The data can be represented in XML or text format. A simple gzipped log is not plausible, as I may have added or modified data afterwards, whereas an external logging service would be an overkill. Cost is an issue, we are not dealing with financial data or so, but rather some simple user generated content, where some malicious users tried to blame the operator in the past when things escalated and went to court. My question: Is there some kind of signing software for Linux that signs each element of a log in such a way, that it can be easily shown that no element can be added or modified afterwards? Plug-Ins into some free Splunk Alternatives would be fine too. Ideally the software I am looking for should be under a GPL or similar license. I could probably achive something like this by using PGP/GPG sgning functions and including the previous elements signituares within the following element, but I would prefer to use some program where you do not have to argue about the validity of your own code. Note to mods: I am not asking this question on Stackoverflow, because I am not looking for writing own code for reasons described above. I think this question rather fits into serverfault than superuser, as server-side logging software is discussed rather here than on superuser.

  • Which free RDBMS is best for small in-house development?

    - by Nic Waller
    I am the sole sysadmin for a small firm of about 50 people, and I have been asked to develop an in-house application for tracking job completion and providing reports based on that data. I'm planning on building it as a web application. I have roughly equal experience developing for MySQL, PostgreSQL, and MSSQL. We are primarily a Windows-based shop, but I'm fairly comfortable with both Windows and Linux system administration. These are my two biggest concerns: Ease of managability. I don't expect to be maintaining this database forever. For the sake of the person that eventually has to take over for me, which database has the lowest barrier to entry? Data integrity. This means transaction-safe, robust storage, and easy backup/recovery. Even better if the database can be easily replicated. There is not a lot of budget for this project, so I am restricted to working with one of the free database systems mentioned above. What would you choose?

  • How to reduce memory consumption an AWS EC2 t1.micro instance (free tier) ubuntu server 14.04 LTS EBS

    - by CMPSoares
    Hi I'm working on my bachelor thesis and for that I need to host a node.js web application on AWS, in order to avoid costs I'm using a t1.micro instance with 30GB disk space (from what I know it's the maximum I get in the free tier) which is barely used. But instead I have problems with memory consumption, it's using all of it. I tried the approach of creating a virtual swap area as mentioned at Why don't EC2 ubuntu images have swap? with these commands: sudo dd if=/dev/zero of=/var/swapfile bs=1M count=2048 && sudo chmod 600 /var/swapfile && sudo mkswap /var/swapfile && echo /var/swapfile none swap defaults 0 0 | sudo tee -a /etc/fstab && sudo swapon -a But this swap area isn't used somehow. Is something missing in this approach or is there another process of reducing the memory consumption in these type of AWS instances? Bottom-line: This originates server freezes and crashes and that's what I want to stop either by using the swap, reducing memory usage or both.

  • Storing large array of tiles, but allowing easy access to data

    - by Cyral
    I've been thinking about this for a while. I have a 2D tile bases platformer in XNA with a large array of tile data, I've been running into memory problems with large maps. (I will add chunks soon!) Currently, Each tile contains an Item along with other properties like how its rotated, if it has forground / background, etc. An Item is static and has properties like the name, tooltip, type of item, how much light it emits, the collision it does to player, etc. Examples: public class Item { public static List<Item> Items; public Collision blockCollisionType; public string nameOfItem; public bool someOtherVariable,etc,etc public static Item Air public static Item Stone; public static Item Dirt; static Item() { Items = new List<Item>() { (Stone = new Item() { nameOfItem = "Stone", blockCollisionType = Collision.Solid, }), (Air = new Item() { nameOfItem = "Air", blockCollisionType = Collision.Passable, }), }; } } Would be an Item, The array of Tiles would contain a Tile for each point, public class Tile { public Item item; //What type it is public bool onBackground; public int someOtherVariables,etc,etc } Now, Most would probably use an enum, or a form of ID to identify blocks. Well my system is really nice just to find out about an item. I can simply do tiles[x,y].item.Name To get the name for example. I realized my Item property of the tile is over 1000 Bytes! Wow! What I'm looking for is a way to use an ID (Int or byte depending on how many items) instead of an Item but still have a method for retreiving data about the type of item a tile contains.

  • Running game, leaving game and continuing animation

    - by Madrusec
    I have been trying to learn some Actionscript recently and have been trying to run an interactive story that at one point turns into an extremel simple shooter game. After the player either wins or looses, then he/she is taken to the rest of the animated story. So I have everything up to the point where the games runs (successfully) but for some reason I am unable to have flash run the rest of the frames, most of which have no code at all. This is the code for scene 1: stop (); import flash.display.MovieClip; import flash.events.MouseEvent; import flash.utils.Timer; import flash.events.TimerEvent; var stoneInGame:uint; var stoneMaker: Timer; var container_mc: MovieClip; var cursor:MovieClip; var score:int; var anxiety:int; var anxiety_mc :MovieClip = new mcAnxiety(); //stage.addChild( anxiety_mc ); function initializeGame():void { stoneInGame = 10; stoneMaker = new Timer(1000, stoneInGame); container_mc = new MovieClip(); addChild(container_mc); container_mc.addChild(anxiety_mc); anxiety_mc.x = 497; anxiety_mc.y = 360; stoneMaker.addEventListener(TimerEvent.TIMER, createStones); stoneMaker.start(); cursor = new Cursor(); addChild(cursor); cursor.enabled = false; Mouse.hide(); stage.addEventListener(MouseEvent.MOUSE_MOVE, dragCursor); score = 0; anxiety = anxiety_mc.totalFrames; anxiety_mc.gotoAndStop(anxiety); } function dragCursor(event:MouseEvent):void { cursor.x = this.mouseX; cursor.y = this.mouseY; } function createStones(event:TimerEvent):void { var stone:MovieClip; stone = new Stone(); stone.x = Math.random() * stage.stageWidth; stone.y = Math.random() * stage.stageHeight; container_mc.addChild(stone); } function increaseScore():void { score ++; if(score >= stoneInGame) { dragCursor.stop(); createStones.stop(); stoneMaker.stop(); trace("you wind!"); } } function decreaseAnxiety():void { anxiety--; if(anxiety <= 0) { stoneMaker.stop(); trace("you lose!"); } else { anxiety_mc.gotoAndStop(anxiety); } increaseScore(); } initializeGame(); So what I tried to do was adding gotoAndPlay() inside both the decreaseAnxiety and increaseScore functions after the trace statements and referenced a frame where I have more keyframes that continue a story. However, Flash just goes back to the beginning of the timeline and I even the functions that change and control the cursor seem to be running. This leads me to believe that I need to make sure that I tell flash o stup running certain functions before jumping to another frame. However, it seems to me that I would still have the same issue and not be able to continue in the timeline. Is there something I am missing? How can I jump out of all this code once the game finishes and simply continue playing the rest of the frames? Any pointers would be greatly appreciated. Thank you

  • Are there any decent free JAVA data plotting libraries out there?

    - by Kurt W. Leucht
    On a recent JAVA project, we needed a free JAVA based real-time data plotting utility. After much searching, we found this tool called the Scientific Graphics Toolkit or SGT from NOAA. It seemed pretty robust, but we found out that it wasn't terribly configurable. Or at least not configurable enough to meet our needs. We ended up digging very deeply into the JAVA code and reverse engineering the code and changing it all around to make the plot tool look and act the way we wanted it to look and act. Of course, this killed any chance for future upgrades from NOAA. So what free or cheap JAVA based data plotting tools or libraries do you use? Followup: Thanks for the JFreeChart suggestions. I checked out their website and it looks like a very nice data charting and plotting utility. I should have made it clear in my original question that I was looking specifically to plot real-time data. I corrected my question above to make that point clear. It appears that JFreeChart support for live data is marginal at best, though. Any other suggestions out there?
