I mean I can receive the response from the server and store it in a string variable. I do it by using the delegate method:\n\n - (void)connectionDidFinishLoading:(NSURLConnection *)connection \n\n\nSo there is no problem at this side.\n\nOn the other hand I can also pass a variable to viewControllerB from viewControllerA by using:\n\n-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender{\n if([segue.identifier isEqualToString:@\"vcSegue\"]){\n ViewControllerB *controller = (ViewControllerB *)segue.destinationViewController;\n controller.stringVariable = @\"content of the string\";\n }\n}\n\n\nThe think is when I want to pass the string variable which I have from the server to the viewControllerB I face with a problem that the variable comes null. so how can I control the push action? because what i understand is -(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender should work after the - (void)connectionDidFinishLoading:(NSURLConnection *)connection I mean, I should have the response from the server successfully, then push action should be performed but I cant figure out how to do. thanks for any kind of help."

"How do I find the most recent event in sequence based on the timestamp of another event",
"I have a table of app event data. Each row has a user_id, a timestamp, a page_id, an event_name, and other fields. The events I care about right now are the page_open and button_click events, but there are 10 other event types that could happen in between, like scrolling. The user might open the same page multiple times, but only click a button on the page every so often, like you see in the example below.\nuser_id timestamp page_id event_name\n------- ---------- ------- --------------\n 71 12:00:34 307 page_open\n 88 13:01:44 307 page_open\n 71 13:02:09 307 page_open\n 71 13:02:11 307 scroll\n 71 13:04:41 307 page_open\n 71 13:04:42 307 scroll\n 71 13:04:45 307 button_click_a\n 71 13:08:30 307 page_open\n 88 13:09:01 307 button_click_b\n\nFor each page_open event for each user, I want an additional column that tells me if a button was eventually clicked. I don't have a page "session" to use, so I have to look for the max page_open timestamp that occurred before the button_click timestamp. Said another way, I want to transform the above table into the following table\nuser_id timestamp page_id event_name button_event\n------- ---------- ------- ---------- --------------\n 71 12:00:34 307 page_open NULL\n 88 13:01:44 307 page_open button_click_b\n 71 13:02:09 307 page_open NULL\n 71 13:04:41 307 page_open button_click_a\n 71 13:08:30 307 page_open NULL\n\nI tried to separate the page_open and button_click events into two tables and do a LEFT JOIN on user_id and page_id like you see below, but of course that didn't work because it matched the button clicks to all page_opens with that page_id. I only want to match the button click to it's corresponding page_open event.\nSELECT\n a.user_id,\n a.timestamp,\n a.page_id,\n a.event_name,\n b.event_name AS button_event\nFROM\n (SELECT * FROM events WHERE event_name = 'page_open') a\nLEFT JOIN\n (SELECT * FROM events WHERE event_name = 'button_click_a' OR event_name = 'button_click_b') b\nON\n a.user_id = b.user_id AND\n a.page_id = b.page_id\n;\n\nI'm new to working with event data like this.

"Can I delete missing associations using accepts_nested_attributes_for in rails?",
"TL;DR\n\nThis seems like it should be really simple. I want to set up #accepts_nested_attributes_for such that when I save the parent class with any non-empty params set for the the child class, it deletes any other children that aren't directly referenced by their id in the params.\n\nFor some reason I'm really struggling to find a sensible way of doing this.\n\nThat's really it.\n\nLonger version\n\nI have a model, Pledge:\n\nclass Pledge < ActiveRecord::Base\n has_many :companies, dependent: :destroy\n accepts_nested_attributes_for :companies\n\n # Other stuff\nend\n\n\nAnd a corresponding Company model:\n\nclass Company < ActiveRecord::Base\n belongs_to :pledge\nend\n\n\nSuppose I have company_1 (id: 1, name: company_1) already saved on pledge_a, and I then call pledge_.update(params), where params either doesn't reference a company id, thus:\n\n{ \n \"someotherval\"=>\"5\",\n \"id\"=>\"10\",\n \"companies_attributes\"=>\n { \n \"0\"=>\n { \n \"name\"=>\"company_2\" \n }\n }\n}\n\n\nor (exactly as above, but) with a different id for the companies in question:\n\n{ \n \"someotherval\"=>\"5\",\n \"id\"=>\"10\",\n \"companies_attributes\"=>\n { \n \"0\"=>\n { \n \"id\"=>\"2\"\n \"name\"=>\"company_2\" \n }\n }\n}\n\n\nWhat's the simplest way to instruct Rails delete any companies that aren't included in the params, ie to create a fresh set every time I call #update with any present company in the nested params?\n\nI've tried quite a few things:\n\nUsing a before_save hook on Pledge to delete companies \n- this seemed to delete them after the companies were saved, so that I always ended up with a companyless-pledge\n\nBuilding up an array of companies by adding a :reject_if block to the accepts_nested_attributes_for a line and then using it for a destroy_all_companies after_save hook\n- this didn't work because at some point Rails seemed to re-initialize the pledge, so that by the time we hit the hook, the array had vanished\n\nWriting some code in the controller before I call #update to delete the companies\n- this is the hack I've been reduced to, but it's horrible. Firstly I don't always want to delete the companies if I'm passing in params that don't include any nested company params. Secondly I have to go through the params and delete any non-empty company #id values, otherwise Rails explodes when it can't find the company in question. Thirdly if the validations fail and the Pledge doesn't update, I've now deleted all the companies when I didn't want to.\n\nThere must be a saner way to do this... right?"

"Calling Python through ssh in Python script causes \"Illegal instruction (core dumped)\"",
"I have a Python script call.py to log in to another machine through ssh and execute another Python script saved on this machine, something like this\n# call.py\nimport os\n\n# log into user@host machine and execute python script\nos.system("sshpass -p password ssh user@host '( python3 my_script.py )'")\n\n\nbut when I try to run it I get this error\nIllegal instruction (core dumped) ( python3 my_script.py )\n\nI tried a few things:\n\nIf I log into ssh and launch python3 my_script.py through the terminal it works\nI also tried running the same call.py script without the ssh part, so trying to launch my_script.py on the same machine and it works\n\nIt seems that only the combination of ssh + python inside python that gives me this error. Any pointers on what could cause the error will be very much appreciated.\nEdit: I didn't realize it would play a role, but I'm adding now the important detail that the target machine is an Nvidia Jetson board."

"Retrieve value of a spinner after validation",
"I have a problem to retrieve the value of a spinner when I want to validate my insertion.\n\nhere is how I fill my spinner :\n\nArrayList<HashMap<String, String>> myArrayList;\nmyArrayList= new ArrayList<HashMap<String, String>>();\nfor (int i = 0; i < studentList.length(); i++) {\nJSONObject c = studentList.getJSONObject(i);\nString id = c.getString(\"id\");\nString name = c.getString(\"name\");\nHashMap<String, String> map = new HashMap<String, String>();\nmap.put(\"id\", id);\nmap.put(\"name\", name);\nmyArrayList.add(map);\n}\n\n\nand after :\n\nSpinnerAdapter studentAdapter = new SimpleAdapter(\nMyActivity.this, myArrayList,\nR.layout.student, new String[] { \"id\", \"name\"},\nnew int[] { R.id.id, R.id.name });\nmySpinner.setAdapter(studentAdapter);\n\n\nWhen I click on my button \"OK\", and I get the value of the spinner with\n\nmySpinner.getSelectedItem().toString();\n\n\nI get : \n\n\n {id=2, name=Smith}\n\n\nBut i'm sure there is another method to retrieve only the name, but how? By getting the adapter with the spinner? It is my problem...\n\nThank you"
