• Cross-Platform Automated Mobile Application UI Testing

  - by thetaspark

  My dissertation is about developing a tool for testing mobile applications from the GUI. Primary device is Android, but it should support Blackberry or iOs etc. I found some frameworks using Google, e.g MonkeyTalk. I am not so sure, but what I want to develop might be a mini MonkeyTalk, with minimal functionality, focused on the GUI of the application(s) to be tested. My questions: What framework(s)? I am good with Java. Can I use the xUnit family for this, and how? What should I be reading/studying? Any suggestions, links for tutorials, documentations, howtos, etc., would be very helpful. Thanks in advance.

• Rationale behind freeware projects

  - by VexXtreme

  I've seen some freeware projects in the past where the author(s) invested a significant amount of their personal time and resources and never even considered charging for the software. A lot of these projects were donation based, and from what I've heard, donationware can never be a viable business model (even to simply support development costs) because most people choose not to donate if given an option. A lot of these projects eventually shut down because their authors could not sustain them further. Granted, some people simply like making the community happy (or something), but if you're struggling to keep your project alive, why not charge some small amount such as $10 simply to stay operational? If people find your software useful (and a lot of people found those projects VERY useful) they won't have a problem paying such a small amount. The question is: if you have a popular app that people like and download in great numbers, why not put a price tag on it? Why do it for free?

• What is good side of PageRank?

  - by SharkTheDark

  I am doing research about backlinks/PR/SEO/Search Result position and all I read about is that PageRank is not important, that it worth before but now it's not important at all. Only thing I found useful about it that is "change Search Result position", but ONLY if there are two sites with same keywords and same text content value, then Search Engine will check which site has higher PR and place that site above lowest one. Google counts PR importance as 20% for displaying search rankings, and Yahoo! is like 3%... Correct me if I am wrong... Is there any other good thing from it?

• How to find the occurrence of particular character in string - CHARINDEX

  - by Vipin

  Many times while writing SQL, we need to find if particular character is present in the column data. SQL server possesses an in-built function to do this job - CHARINDEX(character_to_search, string, [starting_position]) Returns the position of the first occurrence of the character in the string. NOTE - index starts with 1. So, if character is at the starting position, this function would return 1. Returns 0 if character is not found. Returns 0 if 'string' is empty. Returns NULL if string is NULL. A working example of the function is SELECT CHARINDEX('a', fname) a_First_occurence, CHARINDEX('a', fname, CHARINDEX('a', fname)) a_Second_occurrence FROM Users WHERE fname = 'aka unknown' OUTPUT ------- a_First_occurence a_Second_occurrence 1 3

• Ubuntu 11.10 Unity - all Windows decorations disappear after I maximize any window

  - by korda

  When I maximize some of the windows all decorations disappear (by all, I mean on all windows)... Is that common issue on Unity or I'm just unlucky to have some prone to that bug configuration? Anyone have idea how to fix this? EDIT: It won't fix after unmaximize. It seems like maximazing window simply crashes window decorator. Decoration isn't displayed for all existing windows and any new ones. Only way I found to fix this is to run compiz --replace (but this ruins current windows placement - all windows end up on same desktop). It happens almost every time I maximize window.

• problems with graphic performance in Ubuntu 12.04

  - by Falk

  in advance: my English is not perfect ;) processor: Intel® Core™2 Duo CPU E8500 @ 3.16GHz × 2 memory: 3,9 GiB graphics: GeForce GTX 460 Ubuntu 12.04 32-Bit fresh installed (previously 11.10 32-Bit) driver: NVIDIAs accelerated Driver (Version current-updates) probelm: In Ubuntu 12.04 I have problems with the performance of the graphics (games for example: Volley Brwawl, Neverball, Beep and Minecraft), and effects of windows (always at minimize, maximize...) There are laggs at animations, and the laggs in games are extremely annoying. Problems occur only in Ubuntu 12.04, everything was good in 11.10. No Problems with YouTube videos, HD videos. Is there a solution? BBecause I have found nothing here in the Forum and on Google. Or is an update coming soonfor driver or whatever? (This Bug is already registered in Launchpad.) Thank you!

• What are common patterns for handling possible pluralization in message properties?

  - by C. Ross

  Obviously users like to see text properly pluralized, and pluralization schemes vary in the various written languages one may encounter. When internationalizing an app, what pattern(s) are useful for handling messages with possible pluralization? What about messages with multiple possible pluralization? For example: "N review(s):" One pattern would be reviews.title.singular="{0} review:" reviews.title.singular="{0} reviews:" And this may not support all languages. Or a more complicated case: "Found M question(s) with N comment(s)." This would be difficult to support in English?

• HTML5-Canvas: worth using ImpactJS or other framework?

  - by John

  I've been making an HTML5 game without any type of external framework. I haven't found a reason to use one so far. However, there is one thing I'm wondering about. On my Galaxy Nexus, I get about ~40fps. While that would usually be a decent framerate, my game is a rather fast paced game with a gamepad. Because of this, it feels very unsatisfying to play when not capped at 60fps. Are there frameworks out there that can improve performance without toning down on graphics? Or is there something I could do myself without necessarily having to use a framework? I've looked over the basic things such as sticking to integer coordinates, but I didn't see an increase in performance whatsoever? I did some testing with jsperf and results were virtually identical. Does this depend more on the browser?

• IPC linux huge transaction

  - by poly

  I'm building and application that requires huge transactions/sec of data and I need to use IPC to for the mutithreaded mutliprocceses communication, I know that there are a lot of methods to be used but not sure which one to choose for this application. This is what the application is gonna have, 4 processes, each process has 4 threads, the data chunk that needs to be transferred between two or more threads is around 400KB. I found that fifo is good choice except that it's 64K which is not that big so i'll need to modify and recompile the kernel but not sure if this is the right thing to do? Anyway, I'm open to any suggestions and I'd like to squeeze your experience in this :) and I appreciate it in advance.

• Compiz Expo freezes programs

  - by James

  I'm using 11.10, and when I use the Expo feature and then return to a active workspace, any open windows are click-able, but they don't actually change. Here's what I mean: In Google chrome, after Expo, I can click on links/new tab button, etc. However, though the mouse will spin and the program is actually working, the program won't update visibly unless I minimise/restore (or vice-versa) the entire window. Edit: I've found others who have the same problem (unrelated to Expo). It would seem that though the program remains running, its content won't refresh unless it is first maximized then minimized. Edit: Problem solved by resetting compiz.

• K3b - cdrecord has no permission

  - by user64386

  I use Ubuntu 12.04. Today I tried to burn an ISO file in a DVD-R disk using K3b. It used to work, but today, after one and a half minutes, it stopped saying that "cdrecord has no permission to open the device". I searched for a solution, and I found that I had to do something with k3bsetup. I tried to use it, but I had no idea what to do, and I couldn't find a guide, so I checked cdrecord and clicked apply. Now there is another error; it says "cdrecord returns an unknown error! (code 254)". What should I do?

• 12.04 Install Freeze, Blank Cursor Page

  - by smmilke

  I have been trying to install Ubuntu 12.04 via a live CD and most recently with the windows installer I found on line. The windows installer seemed to be working; I selected the partitioned portion of the drive on which to install Ubuntu and started the install process. The process freezes on a page with a flashing cursor and nothing else displayed. I have read about similar problems but have not been able to implement any of the solutions people have discussed. Any ideas on what might be hanging up the process, or how to get a better idea of what is causing the problem would be helpful. If anyone has had this problem and has a solution it would be GREATLY appreciated!

• I Don't Understand Anything About Randomly Generated Worlds [closed]

  - by Alex Larsen

  What tools do I need to make a Minecraft-like generated world? I heard about Perlin noise and Simplex, but I don't understand anything about them. So far all I found on the internet was a Simplex version for C#, and all it has is functions, and this is what I get: Console.WriteLine(Noise.Generate(SomeNumber, SomeNumber, SumNumber)); Outputs random floats. I'm really lost. I don't understand the whole random generated worlds concept. Can someone help me? And if I use the noise thing I don't understand how to use it.

• Client side prediction/simulation Question

  - by Legendre

  I found a related question but it doesn't have what I needed. Client A sends input to move at T0. Server receives input at T1. All clients receive the change at T2. Question: With client-side prediction, client A would start moving at T0, client-side. All other clients receive the change at T2, so to them, client A only started moving at T2. If I understand correctly, client B will always see client A's past position and not his current position? How do I sync both client B and client A?

• System crashes when internet connection is unplugged

  - by Rincewind

  When i first tried to install any ubuntu newer than 10.04 on my netbook (Acer aspire one 722 11,6" WXGA - C-60 Dual Core APU - AMD Radeon HD 6250 - 1x HDMI - 2GB DDR3 - 320GB - 802.11bgN - 6CELL2.2 - BT 3.0 - VGA Webcam), it would fail to boot. I found out that the only fix to this was linking it to the internet via lan-cable during the installation. However, after installing ubuntu 12.04 successfully my system is crashing everytime i unplug the lan-cable. My first thought was disabling the netbook´s w-lan (via the band at the top) but it was not fixing the problem. Looking on the taskmanager ('top') during the process brought no further insight, no process was exploding or something like that. As i am out of guesses help would be really appreaciated.

• php.ini modifications has no effect on joomla

  - by user488736

  I have a netbook with a recently installed ubuntu server 12.04 64-bit. I have (only) installed Joomla on it (version 2.5) and now I am trying to tweak the php.ini settings so I can install jomsocial onto joomla. I have changed these settings: upload_max_filesize = 2M post_max_size = 8M to this: upload_max_filesize = 20M post_max_size = 20M in all php.ini-files in my system. Thats six files, found using 'locate': /etc/php5/apache2/php.ini /etc/php5/cli/php.ini /usr/share/doc/php5-common/examples/php.ini-development /usr/share/php5/php.ini-production /usr/share/php5/php.ini-production-dist /usr/share/php5/php.ini-production.cli I have double-checked that these files actually contain the new settings. Still, joomla does not recognize the new settings, stating that upload_max_filesize is still only 2M and post_max_size is still only 8M The same is true after a complete restart of the server. What am I doing wrong here?

• Patches and translations

  - by Chris Wilson

  When changing a string of text as a part of a patch, how should the translation in the .po files be handled? For example, a recent paper cut I've worked on involved changing the string "Reboot Anyway" to "Restart Anyway" when gnome-session detected applications still running during restart. When I greped for the offending string, I found not only the string on the Gtk button, but identical strings in a long list of .po files which I later learned contained translations. The format of these translations of along the lines of msgid:Reboot Anyway <translated text> Changing the text of only the button would results in a discrepancy between the text on the English button and the translation, and changing the msgid line would result in a similar situation. How should I raise the issue that new translations are needed? I know this is a trivial problem in this example, but there are other such bugs that involve rewriting entire paragraphs of text.

• How to set Ubuntu as wireless accespoint in the GUI way?

  - by Agmenor

  My aim is to make my Ubuntu machine be a wireless accesspoint using wifi. Of course I found two AskUbuntu questions already treating that; this one and that one. Nevertheless, as far as I am concerned I would like to set up such a network in the Graphical User Interface (GUI) way. Please avoid solutions with the command line. So a solution suggesting to use Network Manager would be really welcomed. Please name and describe very precisely each step, so I can easily find the equivalent in my own language. Thank you for your answers!

• How do you change your screen's color temperature in Ubuntu?

  - by RPG Master

  I edit my photos on my laptop (yes, I know they have crap displays) and I recently had to replace the screen because the old one just randomly died. The old one had decent color reproduction by default, but this new one is VERY blue. After playing with the Gamma I've gotten it to be a bit better, but it's still pretty blue. So, my question is, how do I go about changing my laptop's display's color temperature? And I don't mean through something like the Red, Green, Blue sliders in the NVIDIA config menu. I'm talking about like adjusting in degrees, like editing a photo's white balance. EDIT: So now I've found Redshift and it's doing me pretty good. I thought it might be helpful if I out here the command I'm using. redshift -t 5000:5000 -g .5 By adding this to my start up commands I should be good. I'm still open to other suggestions, because I'd like something that actually edited my xorg.conf or something like that.

• HP DL360 G4 screen resolution problem

  - by dogmatic69

  I just bought an old blade server to mess about with at home and cant get the thing to work. I have run the installer 11.10 x64 server and that was fine. After installing and rebooting, POST is fine but when grub kicks in the screen shows a popup type box complaining that it cant use the resolution. I have tried different screens and its always the same. I can reboot and go back into the installer and the screen is fine. I tried to follow some guides on-line about changing the resolution but I cant get a terminal. I found one in the installer but that is using the ram as /. the installer says 'the drive is mounted as "/target"' but I don't see that, nor /mnt/target. Could anyone help me configure this and get it running. Thanks.
