"Are there any 'gotchas' involved when invoking BDE through a Delphi COM server or DLL from .NET?",
"I'm asking this as a follow-up to my previous question: What is a good way of accessing dBase files using BDE and Delphi?\n\nIt was suggested that I called upon a Delphi COM server instead of passing data though standard input/output, and I totally agree that such a solution is very limited.\n\nBasically I need a way to call BDE from C#, without using ADO/OLEDB. Origianlly my requirement was having the ability to execute queries directly and having some sort of RecordSet object returned, but I'm also okay with a strongly typed interface with method such as:\n\nuint CreateCustomer(string fname, string lname, string addr, string email)\nuint CreateContract(...)\nbool DeleteContract(...)\n\nI would prefer not having to register a COM server with regsvr32, but rather use Interop and DllImport to call DLL methods directly. Using the latter approach, are there any special considerations with regards to resource cleanup and \"BDE Sessions\" and what not.\n\nAlso, what would be the proper way to handle exceptions and ensure any BDE (or other) resources are freed if exceptions occur?\n\nI have a lot of questions, and I'm not really sure how to present them in a clear way :)\n\nEDIT: I'm fully aware that BDE is 'dead', but I have no control whatsoever over the third-party software that's still using BDE."

"React-hot-loader using craco",

"Kafka topics to Spark Streaming DStream, how to get a Json",
"I'm trying to get the information from a Kafka Topic with Spark Streaming and then parse the json I get in the topic.\nIn order to get the topic in a DStream I use a stringReader and then I use foreach to get every RDD from the DStream:\n\nmyRDD.collect().foreach(println)\n\n\nIn order to convert myRDD into a json (when I print myRDD the format for a json is correct) and extract two fields I need, I've tried to use json4s and tried this:\n\nval jsonEvent = Json.parse(myRDD)\nval srcIp = (jsonEvent / \"src_ip\")\nval dstIp = (jsonEvent / \"dst_ip\")\n\n\nI've also tried to use json4s this way:\n\nval jsonEvent = parse(myRDD).asInstanceOf[JObject]\nval srcIp = jsonEvent / \"src_ip\"\n\n\nBut it's not working correctly either.\n\nThis is the output:\n\njava.lang.NoSuchMethodError: rg.json4s.jackson.JsonMethods$.parse$default$3()Z\n\n\nThese are the versions I'm using:\n\n<dependency>\n <groupId>org.json4s</groupId>\n <artifactId>json4s-native_2.10</artifactId>\n <version>3.5.1</version>\n</dependency>\n<dependency>\n <groupId>org.json4s</groupId>\n <artifactId>json4s-jackson_2.10</artifactId>\n <version>3.5.1</version>\n</dependency>\n\n\nI think that the problem is that I don't understand how exactly I can transform each record in the RDD to a json object to parse it.

This just didn't work, I'm not sure why.\n\nQueue<Data> queue = new LinkedList<Data>();\ntry (SourceDataLine sdl = AudioSystem.getSourceDataLine(someFormat)) {\n sdl.open(someFormat);\n sdl.start();\n\n while(true) {\n int position = sdl.getFramePosition();\n byte[] samples = getSamplesSomehow();\n Data data = new Data(position, samples); // <-- java bean\n\n // display\n if (queue.size > 0 && queue.peek().getPosition() < position - sdl.getBufferSize()) {\n byte[] samplesToDisplay = queue.remove().getSamples();\n displaySamples(samplesToDisplay);\n }\n\n // push new data\n queue.add(data);\n sdl.write(samples, 0, samples.length);\n }\n}\n\nWaiting for buffer to be nearly empty.

"partial class naming for asp.net web form default template",
"My company has visual studio asp.net web site projects. When adding a new web form using the default webform template it will automatically create the codefile with the partial class name using the path and the filename you selected. For example, if you added a new web form named Default.aspx to the path User/Feature/ the partial class name will be User_Feature_Default. This works fine. The issue (which may not be an issue) is that of course if you move those files around it will not update the partial class name. Makes sense. Visual Studio is only going to do so much tweaking. My question is whether or not our development group should update these partial class names when the files are moved into new folders mainly for consistancy sake? Will this cause any other problems? I can't think of any."

"Online calculation for Pandas' exponential moving average",
"Generally, we calculate exponential moving averages as the following:\n\ny_t = (1 - alpha) * y_tminus1 + alpha * x_t\n\n\nwhere alpha is the alpha specified for the exponential moving average, y_t is the resulting moving average, and x_t is the new inputted data.\n\nThis seems to be confirmed in the methodology behind Pandas' implementation of the exponentially weighted moving average as well.\n\nSo I wrote an online algorithm for calculating the exponentially weighted moving average of a dataset:\n\ndef update_stats_exp(new, mean):\n mean = (1 - ALPHA) * mean + ALPHA* new\n return mean\n\nHowever, this returns a different moving average compared to that of Pandas' implementation, called by the following two lines of code:\n\nexponential_window = df['price'].ewm(alpha=ALPHA, min_periods=LOOKBACK, \n adjust=False, ignore_na=True)\ndf['exp_ma'] = exponential_window.mean()\n\nIn both of the above pieces of code, I kept ALPHA the same, yet they resulted in different moving averages, even though the documentation that Pandas provided on exponentially weighted windows seems to match the methodology I had in mind. \n\nCan someone elucidate the differences between the online function I've provided for calculating moving average and Pandas' implementation for the same thing? Also, is there an easy way of formulating Pandas' implementation into an online algorithm? \n\nThanks so much!"

Will it not somehow adversely affect the architecture principles (maintenance, testability, etc.)?\nHow do we handle things like defer db.Close()?\n\nI mean, we'd obviously want it to defer in relation to the scope main function, so it's problematic to move that code into the Repository \"class\" (unless there's a way to do that with Context?)\n\nOn the other hand, calling NewRepository in main scope but then having the db handle the connection outside of it feels kind of strange.\n\nMost of the examples I've found used the main function so it was easy.

Modules in alpha are not detected while those in beta are found.\n\nIn the results .tgz and .whl files in Windows, all the needed files are there. All is good.\n\nHowever, when the same procedure is done in Linux (Ubuntu to be specific), only the modules in beta are added and some modules in folderB but not other files of different type and the module alpha. sdist will give only the source while bdist and bdist_wheel will give the .pycs only. I understand that sdist is for distributing source files while bdist is for binary files.\n\nMy question is why is the behavior different in Windows and is it possible to produce the same output in Linux (source and .pyc along with other files)?\n\nI am using Python 2.7."

I have created a bone system to ensure that both handles bases stay put in the center of the clock while the handles get dragged about. The problem is that I cannot restrict the user movement within the \"reach\" of each handle (or is there?) and if the mouse happens to be OUTSIDE of the dragged handle at drop point, the MOUSE_UP event does not trigger.\n\nI have also looked for a MovieClipModified event which would work wonders in this case but I could not find it...\n\nIs there a way to get out of this?\n\nTIA"

"Is there a way to simulate Socket and Connection timeout?",
"I have a certain piece of code that integrates with a third party using HTTP connection, which handles socket timeout and connection timeout differently.\nI have been trying to simulate and test all the scenarios which could arise from the third party. was able to test connection timeout by connecting to a port which is blocked by the servers firewall e.g. port 81.\nHowever I'm unable to simulate a socket timeout. If my understanding is not wrong socket timeout is associated with continuous packet flow, and the connection dropping in between. Is there a way I can simulate this?"

"length()function implementation in a linked-list",
"I am implementing a linked-list, and one of the function asks for the number of nodes in the linked list. However, as the requirement says it needs to be done recursively. \n\nHere is my implementation so far.\n\nclass LList {\n public:\n bool isEmpty() const;\n void cons(int x);\n int length() const;\n private:\n struct Node {\n int item;\n Node* next;\n };\n Node* head;\n}\n\nbool LList::isEmpty() const{\n if(head == nullptr)\n return true;\n else\n return false;\n}\nvoid LList::cons(int x){\n Node* temp = new Node;\n temp->item = x;\n temp->next = head;\n head = temp;\n}\n\n\nI can only do this literately, but couldn't make the recursion work.\n\nint LList::length(Node* head) const{\n Node* temp = head;\n if (temp == nullptr) {\n return 0;\n }\n return 1 + length(temp->next);\n}\n\nint LList::length() const {\n return length(head);\n}\n\n\nI tried to use a helper function to do the job, but it's saying declaration is incompatible with int LList::length() const\n\nCan anyone help me with this problem?"

"what happens to the foreground service when associated notification is removed?",
"I have a service running in foreground . I m looking for a way to stop the service from running in foreground when the user touches the notification. I understrand that the foreground service can be removed by calling the stopforeground function . I referred to the android dev docs about foreground service, but it does not mention anything about the behavior of the foreground service when the notification associated with it gets removed. So my question are\n1)It is possible to stop a foreground service by creating a notification that clears when the user touches it ?\n2)How can one be sure that the service is not running in foreground anymore?"

"TextFormField: Show suffixIcon only if text field is wide enough",
"I have a TextFormField component with a suffixIcon. But some of my input fields are quite some, as they only accept 2 or 3 characters. I want to hide the suffixIcon automatically if the text field is too small. Is this possible?\n\nTextFormField(\n decoration: InputDecoration(\n suffixIcon: IconButton(\n icon: Icon(\n Icons.clear,\n color: ThemeColors.iconColor,\n ),\n onPressed: () {\n _controller.clear();\n },\n )\n ),\n controller: _controller \n) \n\n\nEdit:\n\nThe width of the text field is not fixed - I don't know its width. Usually, the text field is integrated into a flexible layout, e.g. in Rows.\n\nSo, in fact, I need to know the width of a flexible text field."

"Converting string values to float and removing strings from list",
"I have a list that looks like this\n\nlst = ['a','b','43.23','c','9','22']\n\n\nI would like to remove the elements that cannot be represented as floats and hence I am doing the following (Attempt 1):\n\nfor i,j in enumerate(lst):\n try:\n lst[i]=float(j)\n except:\n lst.remove(j)\n\n\nWhich leaves the list looking like this\n\nlst = ['b', 43.23, '9', 22.0]\n\n\nwhereas what I need is this\n\nlst = [43.23, 9.0 , 22.0]\n\n\nAnd so I'm doing the following:\n\nfor i,j in enumerate(lst):\n try:\n lst[i]=float(j)\n except:\n pass\nlst = [i for i in lst if type(i) != str]\n\n\nIs there a cleaner way to do this.?\n\nEDIT: Changed the name of example list from 'list' to 'lst' based on the recommendations below."

"Why are table borders not collapsing when caption is positioned?",
"In this fiddle http://jsfiddle.net/jnddfyeq/ I have two tables with border-collapse: collapse. In the first one everything works as expected. In the second one I position the caption with position: absolute and now the borders between the thead and tbody do not collapse.\n\nThis happens in Firefox 38 and IE8 (not in a fiddle.) I have not tested other browsers. Is this behavior standard? If so why?\n\nUPDATE: Same thing happens in Safari."
