"Create an SSH tunnel to legacy application's open socket connection",
"I have a legacy application that I can't modify that accepts an open socket connection on port 8320 that is running on a linux device. \n\nI would like to make it so that any clients trying to connect to the legacy app would have to make an ssh connection which would then tunnel the traffic to open socket connection created by the legacy application on port 8320. \n\nI only want to make changes to the legacy linux device though. I couldn't find any examples that matched my scenario as most of the port forwarding examples involve forwarding traffic to another remote computer. \n\nWhat configuration steps do I need to take?\n\nThanks in advance."

"Read CSV file with 3 columns into Datastream. JAVA Apache Flink",
"I've been struggling for a while setting up a flink application that creates a Datastream<Tuple3<Integer, java.sql.Time, Double>> from a csv file. The columns in this file (columns ID, dateTime and Result) are all String but they should be converted to Integer, java.sql.Time and Double. The other thing I want is to create tumbling windows with data per day and average the values of the result column in that window. The problem is that I dont know the exact syntax for it. See my code below what I tried. The last part I have sum(2), but I want to calculate the average for the windows. I did not see in a function for this in the documentation. Do I need to write a method myself for this?\n\n\nDataStream<Tuple3<String, java.sql.Time>> dataStream = env\n .readfile(path)\n .map()\n .keyBy(0)\n .timeWindow(Time.days(1));"

"How to swap two fields of a struct",
"I've started studying Rust and I'm trying to implement a simple 1D cellular automata. I want to represent the automata state (Board) as struct holding the size and two different vectors (of same size). I tried: \n\nstruct Board {\n n: usize,\n cur: Vec<u32>,\n next: Vec<u32>,\n}\n\nimpl Board {\n fn new(size: usize) -> Board {\n Board {\n n: size,\n cur: vec![0;size],\n next: vec![0;size],\n }\n }\n}\n\n\nSo far so good. I'm also able of mutating both vectors. But then I want to be able to swap both vectors (or rather their references), such as:\n\nfn swap(&mut self) -> &Board {\n let tmp = self.cur;\n self.cur = self.next;\n self.next = tmp;\n self\n}\n\n\nIt fails, with an cannot move out of borrowed content [E0507] which I think I can understand. I also tried mem::swap which I found in a similarly title question without success.\n\nHow can I make this example work ? (Since I'm a total beginner with Rust, don't hesitate to suggest a different data representation)."

Using a view to save item position is definitely not good idea\n\nHere's the important parts of my code:\n\npublic class NotificationAdapter extends RecyclerView.Adapter<NotificationAdapter.NotificationHolder> {\n Context context;\n List<Notification> notifications;\n // Notification is my custom class (POJO)\n public NotificationAdapter(Context context, List<Notification> notificationList) {\n this.context = context;\n this.notifications = notificationList;\n }\n public class NotificationHolder extends RecyclerView.ViewHolder implements View.OnClickListener{\n View view;\n //The 4 TextViews\n TextView titleTv, descTv, timeTv,extraTv;\n //TextView added to hold position of the view item\n TextView positionJugad;\n public NotificationHolder(View itemView) {\n super(itemView);\n titleTv = itemView.findViewById(R.id.notification_subject_tv);\n descTv = itemView.findViewById(R.id.notification_body_tv);\n timeTv = itemView.findViewById(R.id.notification_time_tv);\n extraTv = itemView.findViewById(R.id.notification_extra_info_tv);\n positionJugad = itemView.findViewById(R.id.notification_view_position);\n itemView.setOnClickListener(this);\n this.view = itemView;\n }\n public void bindNotification(Notification notification, int position){\n titleTv.setText(notification.getTitle());\n descTv.setText(notification.getDescription());\n timeTv.setText(notification.getTime();\n extraTv.setText(notification.getExtra());\n positionJugad.setText(\"\"+position);\n }\n public void collapseView(){\n descTv.setVisibility(View.GONE);\n extraTv.setVisibility(View.GONE);\n }\n public void expandView(){\n descTv.setVisibility(View.VISIBLE);\n extraTv.setVisibility(View.VISIBLE);\n }\n @Override\n public void onClick(View view){\n //get the textview that stores position\n TextView jugad = view.findViewById(R.id.notification_view_position);\n if(descTv.getVisibility()==View.GONE){\n expandView();\n }\n else collapseView();\n notifyViewToggle(Integer.parseInt(jugad.getText().toString()));\n }\n }\n @Override\n public NotificationHolder onCreateViewHolder(ViewGroup parent, int viewType) {\n View view = LayoutInflater.from(parent.getContext())\n .inflate(R.layout.notification_item,parent,false);\n return new NotificationHolder(view);\n }\n\n @Override\n public void onBindViewHolder(NotificationHolder holder, int position) {\n Notification notification = notifications.get(position);\n holder.bindNotification(notification,position);\n }\n //To change view state from collapsed to expanded and vice versa\n public void notifyViewToggle(int position){\n\n notifyItemChanged(position);\n }\n\n @Override\n public int getItemCount() {\n return notifications.size();\n }\n}"

"Python NetworkX: edges color in a weighted graph",
"I am trying to plot a fully connected graph with edge weights given by the Gaussian similarity function using the networkx library in Python. When I plot the graph the color intensity of the edges seems to be very mild, which I guess is due to the small connectivity weights (Half-moons fully connected graph ).

"Why are there multiple calls to my function when it has been called only once during iteration?",
"I am working on an Android application which uses Xerces for Iteration. I have a custom method which is called to store a filtered set of data values in it after being iterated through via a while loop. Part of the specific while loop is as follows:\nwhile((n = iterator.nextNode())!= null) {\n ... //other code\n\n object.customMethod(tagName, n.getNodeValue()); //occurs only once per iteration\n Log.i("TAG", tagName + ": " + n.getNodeValue())\n\n ...//other code\n}\n\nThe customMethod received a key and value pair and saves them as Strings using Android's SharedPreferences system. At the moment of being called, the method actually has the key=>value pair, but it appears the method is being called more than once during the same iteration loop. I came to know this after printing out the logcat sample showing the output after each call within customMethod due to having blanks/nulls saved in the preferences when I fetched them later. Why is this happening? A sample output is as shown:\n\nTAG inserted: 500.00 //log call right after insertion within customMethod()\nTAG vc:limit: 500.00 //log call after returning from customMethod()\nTAG inserted:\nTAG inserted:\nTAG inserted: //other calls, which I want to know how and why they are occurring\n\nAll the above occurred during a single iteration of the while loop. Anyone know why this is happening? Something else, it seems the code right after the insertion only runs once, but only the code within the customMethod() gets called several times during the iteration. The custom method is as shown below:\npublic boolean customMethod(String key, String val) {\n boolean inserted = prefs.edit().putString(key, val).commit(); //prefs is global\n Log.i("TAG", (inserted == true ? "inserted: " + val : "not inserted"));\n return inserted;\n}\n\nEdit: The full while loop as requested:\nprivate void setSelectedID(int pos)\n{\n ...\n String id = IDs[pos];\n ...\n\n NodeList descElements = MainActivity.root.getElementsByTagName(VCard.DIRECTORY); //DIRECTORY is a String constant\n Element desc = (Element) descElements.item(0);\n NodeIterator iterator = ((DocumentTraversal)MainActivity.doc).createNodeIterator(desc, NodeFilter.SHOW_ALL, null, true);\n\n Node n;\n VCard object = new VCard(this);\n\n while((n = iterator.nextNode())!= null)\n {\n if(n.getNodeType() == Node.CDATA_SECTION_NODE || n.getNodeType() == Node.TEXT_NODE)\n {\n String tagName = n.getParentNode().getNodeName();\n if(object.containsKey(tagName))\n {\n Element e = (Element) n.getParentNode();\n if(e.hasAttribute("id") && e.getAttribute("id").equals(id))\n {\n object.customMethod(tagName, n.getNodeValue());\n Log.i("TAG", tagName + ": " + n.getNodeValue())\n }\n }\n }\n }\n}"

"<div class=\"bgdiv\"></div>\n<div class=\"fgdiv\"></div>\n\n<a href=\"#\" class=\"mainlink\">LINKA</A>\n\n\nThe bgdiv has no styles at all so these and ZIndex need to be assigned(the others already have z-index properties) and then needs to be assigned a height and width which is \"x\" amount of pixels bigger than link A.\n\nThe bgdiv would then be positioned behind link A and in front of fgdiv so that the bgdiv directly surrounding the link(visually), with a similar effect to padding.\n\nhas anybody got any ideas on how this could be achieved?\n\nEDIT:\n\nSo the image above is as if I'd just clicked on the login button.\nThe green bar div which was initially behind the grey rectangle link surrounder div has now been \"moved up a layer\", but is still behind the text \"login\""

"PodioContact::get_for_app - depreciation whats the alternative?",
"I am using 'PodioContact::get_for_app' to get info using the api and have had trouble getting to the contacts which have filled in a web form with other api calls (ie the people who fill in the form are not podio users and therefore do not appear on in the org or workspace connections/contacts)\n\nI have noticed that podio creates a profile for them and the information entered is converted to just a profile_id but this id does not match any of the id (user or profile) I have for the orgs/apps/workspace users.\n\nI have found that the only way to get to this list of users and profile ids is to use:\n\nhttps://developers.podio.com/doc/contacts/get-space-contacts-on-app-79475279\n\nI have tried various other ways to get this list but only get the ones connected to the workspace who have full logins eg:\n\nPodioSpaceMember::get_all\nPodioContact::get_for_space\nPodioContact::get_all\nPodioContact::get_for_org\n\n\nI am concerned that this api call is being depreciated as I do not see how to retrieve a list of these users otherwise.\n\nIs there an alternative way to get to a list of these users before this is depreciated?"

"Names of `out` variables in a fragment shader",
"I'm having some problem understanding one line in the most basic (flat) shader example while reading OpenGL SuperBible.\n\nIn chapter 6, Listing 6.4 and 6.5 it introduces the following two very basic shaders.\n\n6.4 Vertex Shader:\n\n// Flat Shader\n// Vertex Shader\n// Richard S. Wright Jr.\n// OpenGL SuperBible\n#version 130\n\n// Transformation Matrix\nuniform mat4 mvpMatrix;\n\n// Incoming per vertex\nin vec4 vVertex;\n\nvoid main(void) \n { \n // This is pretty much it, transform the geometry\n gl_Position = mvpMatrix * vVertex;\n }\n\n\n6.5 Fragment Shader:\n\n// Flat Shader\n// Fragment Shader\n// Richard S. Wright Jr.\n// OpenGL SuperBible\n#version 130\n\n// Make geometry solid\nuniform vec4 vColorValue;\n\n// Output fragment color\nout vec4 vFragColor;\n\n\nvoid main(void)\n { \n gl_FragColor = vColorValue;\n }\n\n\nMy confusion is that it says vFragColor in the out declaration while saying gl_FragColor in main(). \n\nOn the other hand, in code from the website, it has been corrected to 'vFragColor = vColorValue;' in the main loop.\n\nWhat my question is that other then being a typo in the book, what is the rule for naming out values of shaders? Do they have to follow specific names?\n\nOn OpenGL.org I've found that gl_Position is required for the out of the vertex shader. Is there any such thing for the fragment shader? Or it is just that if there is only one output, then it will be the color in the buffer? \n\nWhat happens when there is more then one out of a fragment shader? How does the GLSL compiler know which one to use in the buffer?"

"\"Battery saver\" feature killing my music service",
"I'm building a music streaming app for Android.\n\nIn this app, I have a Service which is responsible for playing audio from an HTTP server. Before playing, I make sure to startForeground() and acquire a partial WakeLock, so that my service isn't killed. I also get a WifiLock, just in case.\n\nThe service works fine... as long as my phone isn't on \"battery saving mode\". The minute I turn on battery saving and disconnect my phone from power source, my service is killed with fire!\n\nUnfortunately it doesn't even seem that onDestroy() is called, so my notification from startForeground() stays visible, even if the service is dead.\n\nThe phone is a Samsung Galaxy S6, with Android 6.0.1 on it.\n\nTwo questions:\n\n\nIs there a way I can keep the service alive despite the battery saver thingy?\nIf not, I'd like to know at least when my service is killed, so that I can do a bit of cleanup (remove notification & internal stuff).\n\n\nAny suggestions?"
