"Apply dynamic filters using Tags",
"I have a list of elements which is displayed in a table using ng-repeat. I want to apply dynamic filters which are added using Tags(ng-tags-input). This tag input generates dynamic tags which I want to use as filters. \n\nHere is the plunk I have created. How can I use entries from these tags to create filters.\n\nFor a single element i tried\n\n<body ng-controller=\"MainCtrl\">\n <tags-input ng-model=\"tags\"></tags-input>\n <p>Model: {{tags}}</p>\n <table border=1 cellpadding=10px>\n <tr ng-repeat = \"t in tableData | filter:tags[0].text\">\n <td>{{t.data1}}</td>\n <td>{{t.data2}}</td>\n </tr>\n </table>\n</body>\n\n\nbut this will take only a single element. I want to apply entire entries of tags to be a filter.\n\nI have seen other questions on SO, but they have filters applied as \n\n<tr ng-repeat = \"t in tableData | filter:{data1:someFilteData}\">\n\nHere is one of the fiddle. I am not able to apply filter from JSON Array.\nHow can I do this?"

"password to be used with external service",
"I have an application that uses Django REST server on the backend and I'm integrating with a communication service called QuickBlox that provides real time text and video chat. I have to create a user as well as log in users with the service using a password, and I have some concerns.\n\nThe user will not need to know their password, it is something that is only going to be used in API calls from the server to an API endpoint provided by QuickBlox. The current plan is to make a random string of characters and store that value on the User object. The problem is that the quickblox password is stored in plain text, and I don't want that. Is there any way to store a hashed value of the generated password and then unhash it before sending it as the password in my request to Quickblox?\n\nI was hoping to find something in Django Password docs, but there's nothing on unencrypting a hashed value, for good reason!\n\nMaybe I'm going down the wrong path and someone has another suggestion. The problem is that I need to store a randomly generated password and use that password to issue requests to an external service."

"Bypass Scala Type Erasure (with Guava EventBus)",

However, Scala proves to have a number of nice ways to circumvent Java's erasure problems. Does anybody see another way to achieve this, perhaps using some Scala wizardry?"

"FastAPI how to add ZMQ to eventloop",
"I am surprised this has not really been asked in detail but for some reason i could not find this question or solution anywhere. It seems to be that a lot of people are having a problem where you have a fastAPI application that also needs to communicate to some other microservice (in something more efficient than http messages). I have read all of the zmq documentation on integration into asyncio, but so far i have not found anything about how to add zmq into the eventloop with fastapi (or even starlette for that matter). here is an example of the code from the zmq website:\nimport asyncio\nimport zmq\nfrom zmq.asyncio import Context\n\nctx = Context.instance()\n\nasync def recv():\n s = ctx.socket(zmq.SUB)\n s.connect('tcp://127.0.0.1:5555')\n s.subscribe(b'')\n while True:\n msg = await s.recv_multipart()\n print('received', msg)\n s.close() \n\nThis shows us an async function, which is great, but once again this needs to run in the eventloop alongside the fastAPI coroutine. How is this supposed to be done? The fastAPI documentation does not really provide any interface for us to run a separate coroutine besides a background task. I am not sure if there is any other magic happening in a background task, but for something that needs to communicate with another microservice, i would want this to have scheduling similar to the fastAPI coroutine. Furthermore, you can't start a background task at startup, so you have to do some hokey call to even get it running (it's hacky .. but technically works). Furthermore, it would be even better if we could just register a handler with something like\[email protected]("zmq_recv)\nasync def recv():\n s = ctx.socket(zmq.SUB)\n s.connect('tcp://127.0.0.1:5555')\n s.subscribe(b'')....\n\nThis would, based on config somewhere, allow all messages on the zmq context to automatically go to this function. This would maybe allow us to run zmq INSIDE the fastAPI coroutine, just binding another port, and making sure that all traffic from that port goes to this special app.set method. I would be more than fine with something like this ...\nctx = Context.instance()\n\[email protected]_event("startup")\nasync def startup_event():\n s = ctx.socket(zmq.PULL)\n s.bind('tcp://127.0.0.1:5555').setHandler("zmq_recv") # this setHandler is something magic that tells fastAPI to have all traffic on port 5555 to go to this handler function\n\[email protected]_special_handler("zmq_recv")\nasync def zmq_recv(socket):\n msg = await socket.recv_multipart()\n print('received', msg)\n \n\nThis is ideally what i would like, using the fastAPI coroutine... but having zmq sockets invoke responses to a specific function. Is either creating a coroutine example OR this sort templated example possible? If not, how are people claiming you can use zmq with fastapi efficiently? (i guess background tasks could do the trick.. but it seems really hokey)"

If the name is found it holds onto the Row value. Let's assume that the row is 10. This row value will be used in checking the column values for this row (I.e. C10, J10, and K10). How can I select a single cell and then compare the values within those cells?"

"C++ - CGI - Audio not working properly",
"I have a website with an HTML5 audio element whose audio data shall be served via a cgi script.\nThe markup is rather simple:\n\n<audio controls>\n <source type=\"audio/mpeg\" src=\"audio.cgi?test.mp3\">\n <em>Me, your browser does not support HTML5 audio</em>\n</audio>\n\n\nThe cgi is written in C++ and is pretty simple too, I know there is need of optimizing, e.g. reading the whole file in a buffer is really bad, but that's not the point.\nThis basic version kinda works, meaning the audio is played, but the player does not display the full length and one can only seek through the track in parts that have already been played.\n\nIf the audio file is placed in a location accessible via the web-server everything works fine.\nThe difference between these two methods seems to be, that the client issues a partial-content request if the latter method is chosen and an ordinary 200 if I try to serve the audio data via the cgi at once.\n\nI wanted to implement partial-content serving into the cgi but I failed to read out the environment variable Request-Range, which is needed to serve the requested part of data.\n\nThis leads me to my questions:\n\n\nWhy does the HTML5 player not display the full length of the track if I'm serving the audio data via the cgi script?\nWould implementing a partial-content handling solve this issue?\nIf the partial-content handling is the right approach, how would I access the required environment variables in apache, since I have not found anything about them? Do I need to send a complete HTTP header indicating partial-content is coming, so the client knows he needs to send the required fields?\n\n\nThis is the source of the .cgi:\n\nvoid serveAudio()\n{\n //tried these, were not the right ones\n //getenv(\"HTTP_RANGE\");\n //getenv(\"HTTP_CONTENT_RANGE\");\n\n ifstream in(audioFile, ios::binary | ios::ate);\n size_t size = in.tellg();\n char *buffer = new char[size];\n\n in.seekg(0, ios::beg);\n in.read(buffer, size);\n\n cout<<\"Content-Type: audio/mpeg\\n\\n\";\n cout.write(buffer, size);\n}\n\n\nAny suggestions and helpful comments are appreciated!\nThanks in advance!\n\nP.S.:\n\nForgot to mention that this behaviour applies to FF 31 and IE 11."

"Reset the value to the configuration \"spark.executor.instances\"",
"We have a YARN cluster and we use Spark 2.3.2 version. I wanted to use Spark's dynamic resource allocation while submitting the spark applications but in the spark-defaults.conf file the value of the property spark.executor.instances is set to 16. From my understanding, I should not set spark.executor.instances if we wanted to use dynamic resource allocation. Otherwise, even if the dynamic resource allocation is enabled, it is getting overridden by the property spark.executor.instances.\nI can't edit the spark-defaults.conf, so I wanted to reset the value assigned to spark.executor.instances through the --conf argument to spark-submit. I tried setting it to blank or 0 but in both of the cases, the job failed with spark.executor.instances should be a positive number.\nGiven this situation, how can I successfully use Spark's dynamic resource allocation?.\nOne more observation is, I do not see that the dynamic resource allocation enabled in the spark-defaults.conf file. Isn't it a default property since Spark 2.0?."

"How to manage significant functionality differences between user types in ASP.NET MVC2",
"I think I may have made a mess of my controllers. I have a fairly simple site that allows users of type \"Staff\" or \"Client\" to view Projects. Staff have access to all projects, can add and delete them, add and delete users, assign clients permission to projects, etc.\n\nAs it stands this means I have a UserController and ProjectController, littered with Authentication attributes (ie. so a Client can change his email but nothing else like permissions, and Clients can't add/remove/edit projects but can browse their contents).\n\nAnd also, based on the user type/role, I switch out menu components. Should I be splitting up my controllers to have narrower focus, or is this a candidate for Areas? I \"feel\" like to much of my code is checking whether user X can do action Y based on both his role AND explicit per-project permissions.\n\nPS. I rewrote the subject several times trying to make it shorter :\\"

"Does having multiple activation function type neurons in a single layer make sense?",
"I am wondering if there exists any case or needs for having multiple type of neurons which have different activation functions to each other, mixed within a single layer, and if so, how to implement that using tensorflow Estimator framework.\n\nI can think of simple example for which such a configuration might become useful.\nThink about trying to train a neural network that can predict whether an any given 2D point which has its coordinate value as (x, y), lying inside or outside of the given circle which also has its center and radius defined in a same 2D simple space.\n\nLets say that our circle has its center at (0.5, 0.5), and its radius defined to be 0.5.\nThe strategy for our training might be something like: to generate many points randomly first, and to judge for each point lies whether inside or outside of the circle, so that we can feed those set of randomly generated coordinates as the features and the result of the inside/outside judgement for each of it as its corresponding labels.\n\nThe judgement could easily be done by verifying formula below:\n(x-0.5)^2 + (y-0.5)^2 < r^2\nand this could be transformed as below:\nx^2 - x +y^2 - y + 0.5 < r^2\n\nNow, looking at this last formula, the training might obviously become effective if the neural network itself could obtain the value such as x^2 and y^2 automatically, simply out of its feature value which is given as (x, y).\nFor this, I have come to an idea to mix such an neurons that has f(x)=x^2 as its activation function, amongst the standard ReLU neurons.\n\nTo be honest, I already have done several test implementations of this problem using tensorflow Estimator framework, and in one of those I have seen that giving x^2 and y^2 as the additional features (total 4 feature values) should contribute to the effective training convergence compared to the case of 2 features, but the solution using f(x)=x^2 activation function appeard much smarter to me.\n\nAnd thats how I came up with my question here.\nHope if I could hear any opinion for this.\n\nThank you."

"Why use Pythons 'virtualenv' on Linux when one has 'chroot' (and union/overlay filesystems)?",
"First of all let me state that I am a proponent of generic software (in general ;-).

I mean, can't I just set up a nice fake root tree (possibly using union mounting), chroot into it, and do pip install a package I want in my new environment, and then play around within the bounds of my new environment, running python scripts and what not?\n\nAm I missing something here?\n\nUpdate:\n\nCan't one install packages/modules locally in whatever application directory, I mean, without root privileges and subsequently without overwriting or adding files to /usr/lib or /usr/local/lib? It appears that this is what virtualenv does, however I think it has to symlink or otherwise provide a python interpreter for each environment one creates, does it not?"

"How do I force an SSIS package to NOT reuse execution plans?",

After some big changes to the data which it operates on, the package went from taking 3 minutes to run to taking 3 hours. When I run the package manually in SSDT, or after the server has restarted, it runs fine. After some troubleshooting, I believe it's because the cached execution plan it had was no longer correct for the data it's operating on.\n\nIt there a way to tell SQL Server that when it runs this particular SSIS package, it should recompile everything and get a fresh execution plan?
