"How to show up the second screen again",
"I have an application with a very simple UI. Most of the work (bulk processing of images) is done in background using AsyncTask.\n\nIt just has two Actvities. The first Activity(MainScreen) lets user make some choices and then fires off the job.

If the user selects \"back\" button, while on ProgressScreen, the background task is still continuing. \n\nLater if he wants to go back & see progress, there's no way to do it. It I restart the app, it goes to the MainScreen, not the ProgressScreen. I know the background task is going on, since for now I am logging in logcat a message about each image being processed, but I just don't see a way to go back to ProgressScreen.\n\nI have looked around, I think I need to put something in the onStop() & onRestart() of the ProgressScreen, but not sure what...\n\nI should mention, that this application not for general public, but is for internal use only.

"Creating environment datatype in Haskell",
"In order to obtain honors credit for a course, I have been tasked with recreating an assignment we completed in ML (using the SMLNJ implementation), but using haskell instead. The goal here is to create a datatype environment that binds values to strings.\n\nThe type declaration in ML is:\n\ntype 'a Env = string -> 'a;\n\n\nThe basic functions created are env_new() which creates an empty environment, and env_bind() which takes an environment, string, and value and binds the string to the value while returning a new environment. \n\nTest showing the ML functionality are as follows:\n\n- val e1 = env_new() : int Env;\nval e1 = fn : int Env\n- val e2 = env_bind e1 \"a\" 100;\nval e2 = fn : int Env\n- val e3 = env_bind e2 \"b\" 200;\nval e3 = fn : int Env\n- e1 \"a\";\nuncaught exception NameNotBound\n- e2 \"a\";\nval it = 100 : int\n- e3 \"a\";\nval it = 100 : int\n\n\nMy current declaration of this type in Haskell and related functions is:\n\ndata Env a = Env String a\n\nenvNew :: a -> Env a\nenvNew a = Env a\n\nenvBind :: Env a -> String -> a -> Env a\nenvBind environment name value = Env name value\n\n\nI am having a very hard time figuring out the proper syntax for these definitions. Please respond with any hints that would help me make progress on this. Keeping in mind that this is for honors credit - I do not expect any full solutions but simply some assistance (not that I would reject solutions)."

Then I tried to search on stackoverflow and although there are 2-3 similiar questions they are either not an exact problem or their solutions are not applicable/understandable and require further explanations.\n\nProblem:\n\nOn my PC I do docker-compose build and then docker-compose up and voila, I have my instances up and running without problems.\n\nI want to do the exact same thing but so that every service in docker-compose.yml file starts on its own EC2 Instance (or whichever service that AWS offers). Then I want to be able to change my code and push it to github/gitlab/bitbucket (in my case gitlab) and for it to be deployed to my instances.(but this goes into topic about CI/CD so not important for this exact question)\n\nI think that most of people who are used to docker and docker compose and want to start using AWS will or already have encountered this problem.\n\nA step by step solution( or at least a link or pointing me in the right direction) would be really useful because at the moment there is just too much information on EC2, ECR, ECS, IAM and bunch of other stuff and for a beginner in the AWS world it is really really hard to understand and follow.\n\nEDIT:\n\nI know that it probably isn't that simple but a solution must exists even if it is something as cumbersome as creating every single service by itself on ECS (as mentioned in comments). If it is the only way then sure, I all for it, and I did try several of those tutorials but still didn't succeed in my goal."

"How to maintain similar look and feel of iOS app on older and newer iPhones",
"I have been an iOS developers for a few years. But unfortunately have not developed any product from scratch, but mainly involved in feature implementation and bug fix hence was not able to convincingly answer few questions. Can you please answer the questions (or point me to relevant source) that I was asked during an interview?\n\n\nHow would you design your iOS app so that you make sure that they have similar look and feel in older iPhones (4S, 5 etc) and the newer iPhones (6S, 6S+) which have bigger screens?\n\nMy answer was that we provide images of different resolution (higher resolution for the bigger devices) and name them as per the naming convention defined by apple. \nHe was not so convinced with my answer. \nAre there other aspects than just images that need to be taken care of?\nThere are few functionality and controls and api's that are available in the latest iOS SDK but not in the older once. How would you enable/disable the supported feature in your code depending on the iOS version?\n\nAnswer: I would define an macro containing iOS sdk version number check. I would use this macro to check if the current sdk supports this feature or functionality and then make the api call or add/hide the control. \n\nAre there other efficient and easier ways to achieve the same i mean by not using sdk version check?"

"Will CallableStatement.close() cause performance issue",
"I have a question about performance. \n\nThe app I work on is a Spring MVC app (v3.2.9). It's hosted on a WebSphere Application Server (v8.5.5). It is connected to an AS400 DB2 system (driver is JTOpen v9.1). My app calls a stored procedure on an IBM AS400 system. It is being called using Spring's JdbcTemplate.execute method. Here's the code:\n\njdbcTemplate.execute(new CallableStatementCreator() {\n @Override\n public CallableStatement createCallableStatement(Connection con) throws SQLException {\n CallableStatement cs = con.prepareCall(\"{CALL XXXXXXSP ( ?, ? )}\");\n cs.setString(1, xxx);\n cs.setString(2, xxx);\n return cs;\n }\n }, \n new CallableStatementCallback<String>() {\n @Override\n public String doInCallableStatement(CallableStatement cs)throws SQLException, DataAccessException {\n cs.execute();\n return null;\n }\n });\n\n\nWe're running into some issues where the calling of this procedure occasionally throws an error \"[SQL0501] Cursor C1 not open\" After turning up the logging and reviewing, it looks like this error only happens when the app attempts to re-use a CallableStatement. The respective cursor was closed the last time this CallableStatement was used, which results in the error (I'm not 100% sure if this re-use is expected behavior or not). The error happens around 20 times per day, which is a relatively low percentage as this application has much higher traffic.\n\nMy question is, will adding cs.close(); to the code after cs.execute(); cause a deterioration in the performance of the code?"

(And either losing the parametric construction + test indexing, or having to write many similar tests manually).\n\nNotice that I really NEED to run the filesystem generator each test: while above test is simple and doesn't do much.

I already did that and it works fine.\n\nI am trying to update the SDK tools through Android Studio and even though I already have the SDK and other tools installed on a larger secondary \"E:/\" drive that's 4tb, Android Studio insists on downloading something more than 60gb of files onto my (already almost full) 120gb SSD boot drive where Android Studio is installed.\n\nThe folders that it's downloading are:\n\nC:\\users\\<user name>\\AppData\\Local\\Temp\\PackageOperation##\n\n\nIt only said it was going to take 14GB before I started downloading which makes it all the more frustrating. It's still downloading as I post this, and it's only about 1/4 of the way done but I have to go to work. I'm worried it's going to run out of space and not be able to finish. Is there any way to tell Android Studio to download these to my other HDD?\n\nUpdate: It went to about 70GB and left me with only 1GB of free space before it started deleting the files and freeing up space. It ended up finishing, but I don't know if this was a coincidence or not. It's still too close for comfort so if anyone could help that would be fantastic"

"Find the vertices on the outline of a 3d model",
"I have found a lot of materials on how to draw outline around a model with the help of a stencil buffer, like https://www.opengl.org/archives/resources/code/samples/mjktips/StenciledHaloEffect.html\n\nHowever, this time I need to locate the vertices on the outline, to get their coordinates, but haven't found an elegant way to do so.\n\nI once came across a method that can solve my problem for simple models like cube or sphere. It suggests to check the two triangles that share an edge, if the normals of the two triangles pointing in opposite directions with respect to the camera direction, than the edge they share is on the outline. \n\nThe above method works for simple models like sphere or cube, but not for complex models because it might also picked up those edges that inside the outline from the view of the camera.\n\nIn conclusion, my objective is to find the coordinates of the vertices on the outline, for example, vertices on the red line in the image which you can find at https://gamedev.stackexchange.com/questions/59361/opengl-get-the-outline-of-multiple-overlapping-objects.\n\nBTW, I am doing this using Ogre."

"Symfony2 sessions aren't persisting after page load",
"I'm having an issue with a Symfony2 site. I've got the codebase running on a production server, which is absolutely fine but I'm trying to get another developer started on the project and we're running into issues getting the build up and running. The environments are pretty much identical, the developer is using a Vagrant instance, the same provisioning on that instance was used to provision an EC2 instance on AWS.\n\nWhen a form is submitted the action goes through and stores values to the session using Symfonys session handler before redirecting to another action which makes up step two of the form. I can see in Xdebug that the values are being added to the global $_SESSION variable, however when I reach the next break point in the second action the $_SESSION variable is missing the content that it had on the previous action. I'm not clearing the session anywhere, and as I said it works fine on production.\n\nIt's almost as if Symfony isn't storing session data between page loads, does anybody have any ideas?\n\nThings tried\n\n\nAdding cookie domain to the config \nSetting permissions to 777 (just to test) \nPHP Versions are one minor iteration apart (5.4.28-1 vs\n5.4.27-1)"
