• Problems syncing photos and strange effects of uploaded files from other devices

  - by Daniel

  I have a Galaxy Spica (GT-i5700) Android v2.1, rooted with Leshak dev 7 #123. But never mind the root info, the problem would be the same unrooted. The photos from this phone is stored in "sdcard/images", nevertheless the phone also creates a "sdcard/DCIM" but only stores some thumbnails there. Problem nr 1: U1 only reads the DCIM-folder for automatic photo-upload. So photos stored in this phone is not uploaded. If I move photos to "DCIM" folder, U1 recognises the photos and start uploading them. Possible solution: Could there be an option in the settings, to set preferred photo folder? Problem nr 2: Out of 74 pictures, 12 did not get uploaded. Pressing "Retry failed transfers" in Settings does nothing. Pressing the files where status is "Upload failed, tap to retry" only changes the status to "Uploading..." but nothing gets uploaded. If I upload another file to U1, it is uploaded directly without any problem. It has nothing to do with file size, 1,1 MB files has been uploaded fine whilst some failed are 0,8 MB. Problem nr 3: The photos from DCIM are in my case uploaded to a folder called "Pictures - GT-I5700" in U1. If I log in to the homepage and from there upload another photo in "Pictures - GT-I5700", it shows up in U1 on my phone fine. But when I tap it, U1 downloads the photo to "sdcard/U1/Pictures - GT-I5700". If it sync photos from "sdcard/DCIM" to a specific folder, why not also download files to the same folder from which it is synced? After a while of usage, syncing and uploading files from different clients it would be a mishmash of folders and places files are stored and considering that I see no use of U1 at all. Another question: If my SD card in some way breaks down/some folders cannot be read/card temporarly changed and U1 is running, does U1 consider that as files deleted and also delete from the cloud?

• mod_rewrite and SEO friendliness

  - by John Doe

  My website has an atypical structure and I'm not sure if this could create problems in the long run, specially for SEO positioning purposes. I have a unique, large PHP script, and I use the Apache module mod_rewrite in the .htaccess file to create friendly URLs, for example: RewriteRule ^$ /index.php?section=Main RewriteRule ^createArticle$ /index.php?section=Main&view=CreateArticle RewriteRule ^configuration$ /index.php?section=Configuration RewriteRule ^article/([0-9]{1,10})$ /index.php?section=Article&view=Default&id=$1 RewriteRule ^deleteArticle/([0-9]{1,10})$ /index.php?section=Article&view=Delete&id=$1 RewriteRule ^reportArticle/([0-9]{1,10})$ /index.php?section=Article&view=Report&id=$1 RewriteRule ^logIn$ /index.php?section=Authentication ... So, www.example.com/index.php?section=Article&view=Default&id=105 would become www.example.com/article/105. The only real physical file is index.php, in which the parameters of the URL queried is processed and the corresponding result is outputted. My question is, do the crawling robots (e.g. Googlebot) recognize these links? Do they index the resulting HTML outputted by index.php with the specified parameters as if it was a actual HTML file? Also, would this become a problem when creating a Sitemap?

• System in low graphics, deleted linux, grub rescue, can't access windows

  - by First timer

  So I'm pretty new to Ubuntu but I managed to install it with no big problems on both my desktop and netbook. When I installed it on my brother's netbook everything went horribly wrong and now I fear the system is close to beyond repair. The problem was first that it said it did not have any space left (seemed ridiculous since it had a lot). Then Ubuntu began booting into a "System is running in low graphics mode error" which I then tried to fix, using all the tips I could find in here but nothing helped. I think the graphics error and lack of space might have been related but I can't be sure. Finally I gave up repairing Ubuntu and went for a reinstall. Shouldn't have done that! I read that I should simply open Ubuntu through a live usb and choose GParted to delete the Linux partitions so I did and rebooted accordingly. Next, I was to install Ubuntu but now I am only given the option to wipe the whole disk for Ubuntu, not install along with windows 7. If I access GParted I can still see the ntfs partitions that hold windows 7 (there are 2: one labeled RECOVERY and another labeled OS and boot) so why can't I access them? Btw. the OS and boot has a little red mark with a warning that 1 cluster is referenced to multiple times, don't know what that means. If I boot without the live usb I am sent directly into a grub rescue "black screen of the computer will follow no orders". Please, I know that the easiest might be to simply wipe the whole thing clean but there are important files and programs on windows 7. Is there a way to just access windows? It is a dell inspiron 1018 mini netbook, so I have no cd input and no windows 7 installation cd.

• Computer suddenly won't boot - stops at a flashing prompt

  - by Dave M G

  I have been running Ubuntu on my computer for a long time, and I have been using 11.10 since it became available in October. Suddenly, this morning, when I rebooted, the computer would not reach the log in screen. I go through the standard POST boot sequence, and I also get a splash screen for my Nvidia graphics card, so at least most of the hardware seems to be working. After that, all I get is a flashing text prompt - one blinking white underline character on a screen that is otherwise completely blank. I don't think it is even reaching GRUB. No key input is possible. I have tried various key combinations to try and initiate some kind of interface, be it command line or anything else. The only key combination that works is [CTRL]+[ALT]+[Delete] to reboot. I realize this is likely to be a hardware problem, but it could be an Ubuntu problem(?), so I'm hoping for a specific set of troubleshooting steps so I can diagnose and repair this issue. My current suspicion is that one of the drives in my 2 disk software RAID has failed (even though they should be too new for that). However, this computer is critical to my work, so I'd like to invite advice on any possibilities so as to waste as little time as possible in fixing this machine.

• Centralizing a resource file among multiple projects in one solution (C#/WPF)

  - by MarkPearl

  One of the challenges one faces when doing multi language support in WPF is when one has several projects in one solution (i.e. a business layer & ui layer) and you want multi language support. Typically each solution would have a resource file – meaning if you have 3 projects in a solution you will have 3 resource files.   For me this isn’t an ideal solution, as you normally want to send the resource files to a translator and the more resource files you have, the more fragmented the dictionary will be and the more complicated it will be for the translator. This can easily be overcome by creating a single project that just holds your translation resources and then exposing it to the other projects as a reference as explained in the following steps. Step 1 Step 1 -  Add a class library to your solution that will contain just the resource files. Your solution will now have an additional project as illustrated below. Step 2 Reference this project to the other projects. Step 3 Move all the resources from the other resource files to the translation projects resource file. Step 4 Set the translations projects resource files access modifier to public. Step 5 Reference all other projects to use the translation resource file instead of their local resource file. To do this in xaml you would need to expose the project as a namespace at the top of the xaml file… note that the example below is for a project called MaxCutLanguages – you need to put the correct project name in its place.   xmlns:MaxCutLanguages="clr-namespace:MaxCutLanguages;assembly=MaxCutLanguages"   And then in the actual xaml you need to replace any text with a reference to the resource file. <TextBlock Text="{x:Static MaxCutLanguages:Properties.Resources.HelloWorld}"/> End Result You can now delete all the resource files in the other projects as you now have one centralized resource file.

• 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.

• Changing the Default Windows Phone 7 Deployment Target In Visual Studio 2010

  - by mbcrump

  After you download and install the January 2011 Windows Phone update, you will notice one annoying thing. The default deployment target for Windows Phone Projects in Visual Studio changes to Windows Phone 7 Device. Before the update, it defaulted to the Emulator. I found this extremely annoying as I’m more than likely going to test with the emulator before putting it on my actual device. Now to make things fair, Microsoft told you they were going to switch the default and even provided a solution, but you will have to check a tiny paragraph in the release notes. The good news is that its very easy to do: Simply navigate out to : %LocalAppData%\Microsoft\Phone Tools\CoreCon See the folder named, “10.0”? Go ahead and delete it. Now, the folder will be completely empty and if you fire up Visual Studio 2010 you will see we are now defaulting to the Emulator again. In my opinion, this should have been left at Emulator. Now, new WP7 developers will get a build error when they first start a WP7 project and will not know why until they read the error list.  Subscribe to my feed CodeProject

• ubuntu 12.04 LTS hangs on boot when external monitor is connected

  - by vladeta

  I have a problem with my fresh installed Ubuntu 12.04 LTS on my Dell M4600: nVidia quadro 2000M i7-2860 16GB ram 128GB SSD Dell/Samsung 750GB HDD IPS RGB laptop display When it is connected via DP++ to the external Dell U2311H monitor, it hangs on boot or when wakening from suspend. If I detach the DP cable it boots normally. I have tried all combinations that I have found, as adding to grub: "no splash", "boot=pci", "acpi=off", etc... I have also changed in nVidia X settings that external monitor is the primary one and also tried to delete monitor.xml file. There is no change it hangs each time after grub. It starts to load daemons then both screens are blank and then completely hangs with beep sound. What I discovered is if I detach the cable and wait for about 2 sec after grub starts booting and then physically connect DP cable while the Ubuntu is still booting everything works normally and I have a picture on my external screen while the laptop screen is off, just as I wanted. Do you maybe know how to solve this issue? Thank You.

• Am I programming too slow?

  - by Jonn

  I've only been a year in the industry and I've had some problems making estimates for specific tasks. Before you close this, yes, I've already read this: http://programmers.stackexchange.com/questions/648/how-to-respond-when-you-are-asked-for-an-estimate and that's about the same problem I'm having. But I'm looking for a more specific gauge of experiences, something quantifiable or probably other programmer's average performances which I should aim for and base my estimates. The answers range from weeks, and I was looking more for an answer on the level of a task assigned for a day or so. (Note that this doesn't include submitting for QA or documentations, just the actual development time from writing tests if I used TDD, to making the page, before having it submitted to testing) My current rate right now is as follows (on ASP.NET webforms): Right now, I'm able to develop a simple data entry page with a grid listing (no complex logic, just Creating and Reading) on an already built architecture, given one full day's (8 hours) time. Adding complex functionality, and Update and Delete pages add another full day to the task. If I have to start the page from scratch (no solution, no existing website) it takes me another full day. (Not always) but if I encounter something new or haven't done yet it takes me another full day. Whenever I make an estimate that's longer than the expected I feel that others think that I'm lagging a lot behind everyone else. I'm just concerned as there have been expectations that when it's just one page it should take me no more than a full day. Yes, there definitely is more room for improvement. There always is. I have a lot to learn. But I would like to know if my current rate is way too slow, just average, or average for someone no longer than a year in the industry.

• Strategies for avoiding SQL in your Controllers... or how many methods should I have in my Models?

  - by Keith Palmer

  So a situation I run into reasonably often is one where my models start to either: Grow into monsters with tons and tons of methods OR Allow you to pass pieces of SQL to them, so that they are flexible enough to not require a million different methods For example, say we have a "widget" model. We start with some basic methods: get($id) insert($record) update($id, $record) delete($id) getList() // get a list of Widgets That's all fine and dandy, but then we need some reporting: listCreatedBetween($start_date, $end_date) listPurchasedBetween($start_date, $end_date) listOfPending() And then the reporting starts to get complex: listPendingCreatedBetween($start_date, $end_date) listForCustomer($customer_id) listPendingCreatedBetweenForCustomer($customer_id, $start_date, $end_date) You can see where this is growing... eventually we have so many specific query requirements that I either need to implement tons and tons of methods, or some sort of "query" object that I can pass to a single -query(query $query) method... ... or just bite the bullet, and start doing something like this: list = MyModel-query(" start_date X AND end_date < Y AND pending = 1 AND customer_id = Z ") There's a certain appeal to just having one method like that instead of 50 million other more specific methods... but it feels "wrong" sometimes to stuff a pile of what's basically SQL into the controller. Is there a "right" way to handle situations like this? Does it seem acceptable to be stuffing queries like that into a generic -query() method? Are there better strategies?

• Self-imposed lockout from program

  - by Alex

  I'm plagued with a lack of willpower. I recently started looking for solutions, and came across a program for macs called SelfControl which completely blocks one's access to a given set of websites for a given period of time (you can delete the program/restart your computer/do almost anything and it will still block those sites for the specified time period, and doesn't require a password to do it.) Unfortunately, there are no windows analogues. The one that comes the closest is Cold Turkey. It has the functionality whereby you set a time in the future, specify a list of websites (or programs - eg explorer, firefox, chrome) and you are blocked from accessing them for the whole duration. No password can undo it, no system reboot, etc. The problem is that the program is a buggy piece of garbage, and in order to ensure that you're not locked out from websites forever, you have to run an uninstaller which is just an exe file accessible at any time which completely defeats the purpose of a self-imposed program lockout. I want to make a better version of that program, or find a simple way to prevent access to a given set of programs over a given period of time with no way around it. I've only taken a few introductory courses in java (math major), but the internet is really having a negative effect on my studies, and the only way I can do work is to eliminate all distractions. What do I need to learn in order to make a program with the following properties: Given a set of .exe files, and a time in the future , this program will prevent access to the given .exe files until current time = given time restarting the computer doesn't interfere with the program, one can't uninstall the program until current time = given time, one can't create another instance of the program to block itself I don't care how much programming knowledge i need to acquire in order to make this program, so please give me a specific list of things that I need to study in order to make this happen, or if something like this exists, then please let me know.

• Crash due to removal of Elements like CCSprite from NSMutableArray

  - by mayuur

  So, here's how it goes. I am currently working on Cocos2d game, which consists of many Obstacles. One obstacle gets added on the screen at an interval of 10 seconds like this. ObstacleSprite* newObstacle = [ObstacleSprite spriteWithFile:@"Obstacle.png" rect:CGRectMake(0, 0, 20, 20)]; newObstacle.position = ccp(mainPlayer1.position.x,10); [self addChild:newObstacle]; [self.arrayForObstacles addObject:newObstacle]; Now, I insert these obstacles into the arrayForObstacles because I also want to keep checking whether the Obstacles and MainPlayer don't collide. I check it with the help of this function. - (void) checkCollisionWithObstacle { if(mainPlayer1.playerActive) { for(int i = 0; i < [self.arrayForObstacles count]; i++) { ObstacleSprite* newObstacle = [self.arrayForObstacles objectAtIndex:i]; if(newObstacle != nil) { if(CGRectIntersectsRect([mainPlayer1 boundingBox], [newObstacle boundingBox])) { mainPlayer1.livesLeft--; } } } } } THE ISSUE Problem is when I get to certain score, one of the Obstacles gets deleted. Removal of Obstacles works as in First In-First Out (FIFO) mode. So, to delete obstacles, I write the following method : - (void) keepUpdatingScore { //update new score mainPlayer1.score+=10; //remove obstacle when score increases by 5k if(mainPlayer1.score > 5000 && mainPlayer1.score > 0) { mainPlayer1.playerActive = NO; if([self.arrayForObstacles count] > 0) { CCLOG(@"count is %d",[self.arrayForObstacles count]); ObstacleSprite* newObstacle = [self.arrayForObstacles objectAtIndex:0]; [self.arrayForObstacles removeObjectAtIndex:0]; [self removeChild:newObstacle cleanup:YES]; CCLOG(@"count is %d",[self.arrayForObstacles count]); } } else { } } It crashes when score crosses 5000 mark! UPDATE Crash happens when it again goes to the method checkCollisionWithObstacle. This is the THREAD Look. THis is the line Which crashes.

• Resource Acquisition is Initialization in C#

  - by codeWithoutFear

  Resource Acquisition Is Initialization (RAII) is a pattern I grew to love when working in C++.  It is perfectly suited for resource management such as matching all those pesky new's and delete's.  One of my goals was to limit the explicit deallocation statements I had to write.  Often these statements became victims of run-time control flow changes (i.e. exceptions, unhappy path) or development-time code refactoring. The beauty of RAII is realized by tying your resource creation (acquisition) to the construction (initialization) of a class instance.  Then bind the resource deallocation to the destruction of that instance.  That is well and good in a language with strong destructor semantics like C++, but languages like C# that run on garbage-collecting runtimes don't provide the same instance lifetime guarantees. Here is a class and sample that combines a few features of C# to provide an RAII-like solution: using System; namespace RAII { public class DisposableDelegate : IDisposable { private Action dispose; public DisposableDelegate(Action dispose) { if (dispose == null) { throw new ArgumentNullException("dispose"); } this.dispose = dispose; } public void Dispose() { if (this.dispose != null) { Action d = this.dispose; this.dispose = null; d(); } } } class Program { static void Main(string[] args) { Console.Out.WriteLine("Some resource allocated here."); using (new DisposableDelegate(() => Console.Out.WriteLine("Resource deallocated here."))) { Console.Out.WriteLine("Resource used here."); throw new InvalidOperationException("Test for resource leaks."); } } } } The output of this program is: Some resource allocated here. Resource used here. Unhandled Exception: System.InvalidOperationException: Test for resource leaks. at RAII.Program.Main(String[] args) in c:\Dev\RAII\RAII\Program.cs:line 40 Resource deallocated here.

• At the end of my rope

  - by hvgotcodes

  I am a contractor to a big company. Currently, there are three developers on the project, myself included. The problem is the other 2 developers don't really get it. By "it" i mean the following: They don't understand the best practices for the technology we are using. After 6 months of me and others giving them examples there are terrible anti-patterns being used. They are "copy and paste" programmers that produce primarily spaghetti code. They constantly break things, implementing changes but not doing a basic smoke test to see if all is good They refuse/rarely to ask for code-reviews. They refuse/rarely even do basic things like formatting code. No documentation on any classes (jsdocs) Afraid to delete code that doesn't do anything Leave commented code blocks everywhere even though we have version control. I find myself getting more and more frustrated as I format others code, fix bugs, discover functionality that is broken, and create abstractions to remove the spaghetti. I really don't know what to do. I try not to get to frustrated, but it's just a mess. I like these people as people, but I feel like the coding situation is so bad that I could move faster if they simply browsed the web all day. Would it be out of line to ask our manager to review the others svn commit access; commits can only be done after a review by someone who is knowledgeable in what we are doing? As a contractor, I'm not sure if that's the best move. Is there a subtle/not so subtle way of making it clear how many things I am fixing?

• Dreaded SQLs

  - by lavanyadeepak

  Dreaded SQLs We used to think that a SQL statement without a where clause is only dangerous right since running that on a server TSQL is just going to impact the entire table like waving the magic wand. For that reason we should cultivate the habit first to write the statement as select and then to modify the select portion as update. Within the T-SQL Window, I would normally prefer the following first: select * from employee where empid in (4,5) and then once I am satisfied with the results, I would go ahead with the following change: --select * delete from employee where empid in (4,5) Today I just discovered another coding horror. This would typically be applicable in a stored procedure and with respect to variable nomenclature. It is always desirable to have a suitable nomenclature for parameters distinct from the column names and internal variables. This would help quicker debugging of the stored procedures besides enhancing the readability. Else in a quick bout of enthusiasm a statement like   if (@CustomerID = @CustomerID) [when the latter is intended to denote the column name and there is a superflous @ prepended], zeroing in on the problem would be little tricky. Had there been a still powerful nomenclature rules then debugging would have been more straight-forward and simpler right?

• HTG Explains: How Internet Explorer Saves Your Passwords and How to Manage Them

  - by Taylor Gibb

  Privacy is very important when it comes to the digital world, but do you know exactly how your browser saves your passwords ? Read on to find out what goes on behind the scenes. When it comes to web applications, there are many different types of authentication. One of the types is called basic authentication, which is when you navigate to website and a dialog box opens to ask for a username and password. This also happens to be the authentication mechanism defined in the RFC for HTTP. You can see in the screen shot above that there is a check box that you can use to remember your credentials, but what does that do ? You might also ask yourself what happens if you are not using Basic authentication. There is another type of authentication called Form authentication, this is when the authentication is built right into the web application, like the How-To Geek website. This allows the Developer to control the look and feel of the form that we use to log in.

• Recommended formats to store bitmaps in memory?

  - by Geotarget

  I'm working with general purpose image rendering, and high-performance image processing, and so I need to know how to store bitmaps in-memory. (24bpp/32bpp, compressed/raw, etc) I'm not working with 3D graphics or DirectX / OpenGL rendering and so I don't need to use graphics card compatible bitmap formats. My questions: What is the "usual" or "normal" way to store bitmaps in memory? (in C++ engines/projects?) How to store bitmaps for high-performance algorithms, such that read/write times are the fastest? (fixed array? with/without padding? 24-bpp or 32-bpp?) How to store bitmaps for applications handling a lot of bitmap data, to minimize memory usage? (JPEG? or a faster [de]compression algorithm?) Some possible methods: Use a fixed packed 24-bpp or 32-bpp int[] array and simply access pixels using pointer access, all pixels are allocated in one continuous memory chunk (could be 1-10 MB) Use a form of "sparse" data storage so each line of the bitmap is allocated separately, reusing more memory and requiring smaller contiguous memory segments Store bitmaps in its compressed form (PNG, JPG, GIF, etc) and unpack only when its needed, reducing the amount of memory used. Delete the unpacked data if its not used for 10 secs.

• Another VSeWSS Error Resolved (List Template not installed on Farm)

  - by Damon

  Ran into a minor snag today trying to deploy a project with VSeWSS 1.3 - during the deployment it gave me the following error: Error    32    VSeWSS Service Error: Feature '2ade6552-200e-4425-8af5-f1f50c115b7e' for list template '10001' is not installed in this farm.  The operation could not be completed. At first glance, it looked my features were not installing in the correct order because the solution was installing a list that required a custom list definition before the custom list definition was being installed.  After switching the order in the WSP view (View -> Other Windows -> WSP View) -- you can use the up and down arrows on the view pane to switch feature installation order - I had the same error. I decided to try deleting the list, but upon visiting the list in the web interface I received a similar error about how the feature was not installed on the farm.  As such, I could not delete the list through the web interface.  Fortunately, the stsadm.exe tool worked just fine: stsadm.exe -o forcedeletelist -url <urltolisthere>

• Impact Earth Lets You Simulate Asteroid Impacts

  - by Jason Fitzpatrick

  If you’re looking for a little morbid simulation to cap off your Friday afternoon, this interactive asteroid impact simulator makes it easy to the results of asteroid impacts big and small. The simulator is the result of a collaboration between Purdue University and the Imperial College of London. You can adjust the size, density, impact angle, and impact velocity of the asteroid as well as change the target from water to land. The only feature missing is the ability to select a specific location as the point of impact (if you want to know what a direct strike to Paris would yield, for example, you’ll have to do your own layering). Once you plug all that information in, you’re treated to a little 3D animation as the simulator crunches the numbers. After it finishes you’ll see a breakdown of a variety of effects including the size of the crater, the energy of the impact, seismic effects, and more. Hit up the link below to take it for a spin.

• That Tool is cURLy

  When you just use IE, Firefox or Chrome it can be easy to forget that HTTP is about more then just going to check the latest tech news at Engadget. It is a full and rich protocol, and a great way to experience that richness is the powerful command line utility cURL. cURL has a lot of options, but the syntax starts out simple. You can retrieve the contents of a web page with a simple curl http://blogs.claritycon.com/. The results should be the full text of the web page, tags and all. From there, you can use X to specify the HTTP verb to use, POST, PUT, DELETE, PATCH, etc and d to specify the payload of a POST or PUT. I have found cURL to be incredibly useful for two scenarios. First, as a good way to test basic web services. Second, while working a bit with CouchDB and another document based database, cURL has helped me learn more about RESTful APIs, including different verbs and response codes. cURL is a mainstay in our environments and programming languages precisely because it is simple, powerful and discoverable. I encourage more .NET developers to take a look, bask on the command line for a while and enjoy the plain text of the web. And this excellent logo:     -- Relevant Links -- Its not always the case with manuals, but the manual for cURL is quite useful: http://curl.haxx.se/docs/manual.html To make your command line look a little nicer (and more powerful) on Windows, check out Console and add some transparency effects: http://sourceforge.net/projects/console/Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

• How to properly multi thread an RPG

  - by Nagrom_17

  I am working on an RPG type game in Java and I would like to know a few things relating to threading, What is the best way to implement a "wait for this then do this" without hanging the whole thread? Like waiting for a player to move to a location then pick up an item? or to wait one second then attack? Currently I am spawning new threads every time I need to wait for something, but that doesn't feel like the best solution. Any help is appreciated. EDIT: Clarification and an example of how I currently do things. User clicks on an item The function walkToAndPickUp(item) is called which is basically this: Make a new thread so we don't freeze the thread handling input while the player moves. Tell player to move to the item While the player is not at the item(The player moves through an update() function called in a different thread, I don't know how else to do it without freezing threads) Repeat until the player is at the item If the player is at the item then call delete item from map and add to inventory.

• Game crash/Screen freeze recovery (without shell or reboot)

  - by Asavar Tzeth

  I am an old Windows PC gamer, now converted into Ubuntu (Linux) lover. I am even going so far as to attempt to replace all my games in a Windows dual-boot with Wine and it is going well. However... Even if Linux is less prone to crashing, games, especially the windows ones (but also a few native) can crash. My problem is when this is in full screen and the computer becomes non-responsive. In Windows you can solve this with ctrl+alt+delete, but Ubuntu lacks this feature and my only choice is a reboot. Is there any Ubuntu version of this feature? Of course excepting the ctrl+alt+F1, find and kill process method. It is fine if you know how to do it, but too slow and difficult for the typical gamer. I believe strongly in Ubuntu as the future gaming platform in one form or another. If this feature does not exist, then the Ubuntu team should address this as fast as possible, since it is critical for all old Windows gamers. Thank you for your time. Asavar Tzeth (Alias)
