[ "Explicit instantiation of templated class in source file not working", "I'm trying my hand at some template stuff, and the first thing I wanted to do was to separate templated classes into .hpp and .cpp files.

I've also tried with imported_script.__dict__ and vars(imported_script) but these solutions yield to the same. There is also the option of using help(imported_script) which returns the metadata of the script, but until now I haven't found a correct way to get what would be the equivalent to help(imported_script).DATA.\n\nQuestion: Is there a more efficient way of listing the imported script variables so I get specifically the user declared variables?\n\nMore context: I'm using Airflow to generate workflows. Airflow reads a python script that specifies how the workflow (known as DAG in airflow) should be constructed. The script should be in a specific folder so airflow can make the workflow. The specifications of how the workflow should be constructed are given in a json file and vary every time the user wants to generate a workflow, so I must read this json file and then write a new script reusing the code from the template (at least that's the way I've been told to do it). There are several scripts from which I could take the code to reuse and in the future there could be even more (It's dynamic). The script to be chosen depends on one of the parameters in the json." ]

I'm considering using the Singleton design pattern to manage all 3 levels of data. There could be 1 singleton per-realm-model, 3 singletons in total, or there can be one master singleton. \n\nIn both cases, the singletons will have the traditional sup'd up List methods available from RealmModel, \n\n realm.executeTransaction(new Realm.Transaction(){\n @Override\n public void execute(Realm realm){\n realm.copyToRealm(graph);\n }\n });\n\n\nalong with other methods I create:\n\npublic void bulkAdd() {\n @Override\n public void execute(Realm realm){\n for(int i=0; i<100;i++){\n //doStuff();\n... });\n\n\nBefore/After that operation I want to use the Factory Pattern to manage the details of creating and configuring each of the RealmModels. So my question is, should I create 3 singletons, an instance for each RealmModel, 1 master singleton that manages all RealmModels, or use another design pattern?\n\nA side-note, non-priority is that I would also like to take advantage of async if possible, ie:\n\n private void asyncAddQuote() {\n ...\n AsyncTask<Void, Void, Void> remoteItem = new AsyncTask<Void, Void, Void>() {\n @Override\n protected Void doInBackground(Void... params) {...\n\n\nBut I don't know which overall composition of design patterns are best for this application. I need to keep in mind that Realm transactions are limited to one thread. I need to drive UI elements like RecyclerView in the UI thread. In certain modes the application runs as a Service, so in service mode my realm needs to be on the service thread. \n\nI've built the Graph singleton up to recyclerview level and I'm about to build the rest.

[ "Cannot login into gitolite server to clone, but can connect via ssh", "While there are several questions with similar symptoms, none are exactly the same, nor do the solutions presented there solve my issue.\n\nI have set up gitolite successfully, as far as I am aware, using these instructions, and after overcoming this issue.

[ "Data structure for working out free time given used time", "Preamble: I've got a car park with a hundred spaces. I store reservations as free-form start and end times against specified spaces. We currently let people query the car park for a specific time and can easily tell them if there's a free space. But I now have a requirement to advertise how many free spaces there are for 1 hour slots from 7-7, for a span of 5 days. Using the existing query would mean I needed to do 60 queries which is too slow to do interactively and seems just too boggy to do non-interactively.\n\nSo I'm looking for a way to map the time between bookings, and then coerce that into slot availability which I can store separately. This process might be a bit boggy in itself but it might also make querying the database for specific availability somewhat faster.\n\nWhat I want to do is define a day and then \"subtract\" bookings for that day and be left with a list of available time ranges around those bookings, that I can then go onto coerce into hour-long slots.\n\nI'm halfway through doing this myself by starting from a given time, ranging up to the first booking, skipping to the end, and repeating until I hit the end of the slot but it's pretty dull stuff and I'm struggling to believe this hasn't been done before. I'm using Python but I'm happy to port. Something like...\n\ntoday = Day(start=datetime.time(7), end=datetime.time(19))\nprint(today.ranges)\n# [(datetime.time(7), datetime.time(19))]\n\nday.subtract(datetime.time(12), datetime.time(13))\nprint(today.ranges) \n# [(datetime.time(7), datetime.time(12)), (datetime.time(13), datetime.time(19))]\n\n\nI realise I'm probably drifting into a level of specificity where it might only benefit me, but this idea of ranging and splitting time is where I need help. Any ideas?" ]

[ "How might I be able to access a nested struct within a doubly linked list?", "I am trying to use a doubly linked list with a header struct. I believe the header struct is simply supposed to hold a count of how many structs have been created in the list, and the first and last nodes. Now I see two problems. One is connecting the header struct to the subsequent structs and the second is accessing a nested struct that i have within my list nodes (sentry). If anyone could shed some light on what I might be doing wrong it would be greatly appreciated. Code is below. \n\n#include <iostream>\nusing namespace std;\ntypedef struct sentry sentry; \n\nstruct stud{\n string name;\n char grade;\n};\n\nstruct slist {\n int length;\n sentry *first;\n sentry *last;\n};\n\nstruct sentry {\n slist *list;\n sentry *next;\n sentry *prev;\n stud *student;\n};\n\nint main(int argc, char** argv) {\n slist list;\n sentry *n;\n\n n = new sentry;\n\n // Full initialization of the header node.\n list.first = n;\n list.last = n;\n list.length = 0;\n\n n->prev = NULL;\n n->next = NULL;\n n->list = list->last;\n n->student->name = \"test\";\n n->student->grade = 'A';\n\n cout << n->student->name << '\\n';\n cout << n->student->grade << '\\n';\n\n return 0; \n}" ]
