[ "Apply a function to all combinations of two lists in R", "I am trying to find a concise way to apply a function over combinations of lists - with the possible extension of do parallel computing. It seems to me that cross() function from the purrr package is not able to return lists as output.\n\nI tried a nested lapply.\n\ndata1 <- list(a = xts(rep(2, 10), as.Date(1:10)), b = xts(rep(3, 10), as.Date(1:10)), c = xts(rep(4, 10), as.Date(1:10)))\ndata2 <- list(a = xts(rep(1.5, 10), as.Date(1:10)), b = xts(rep(2.5, 10), as.Date(1:10)), c = xts(rep(3.5, 10), as.Date(1:10)), d = xts(rep(4.5, 10), as.Date(1:10)))\ndata <- lapply(data1, function(x) lapply(data2, function(y) y+x))\ndata <- rlist::list.flatten(data)\nsapply(data, first)\n# similar to\n# outer(c(2,3,4), c(1.5,2.5,3.5,4.5), '+')\n# but returns new lists as output\n\n\nThe optimal case would be a fast parallel solution.

[ "How to define the stored procedure input data types , to be based on other columns data types", "I have created a stored procedure in SQL Server 2008 R2 to perform an advanced search like this:\n\nALTER PROCEDURE [dbo].[AdvanceSearch]\n -- Add the parameters for the stored procedure here\n @SearchType nvarchar(10) = null,\n @SerialNumber varchar(50) = null,\n//code goes here\n\n\nCurrently the @SerialNumber variable represents a real column inside a table named Assets. The serial number column has a data type of varchar(50) and it allows null values. \n\nSo what I did is that i manually define the same datatype which is varchar(50). But my question is what will happen if in the future I change the datatype for the SerialNumber column inside the Assets table, then I have to change the type in my stored procedure. \n\nIs there a way to define the datatype for the @SerialNumber parameter inside the stored procedure to be the same as the datatype of a column inside another table? So that if the column type changes the stored procedure parameter will have the new datatype? \n\nThanks" ]

[ ".NET WebSocket closing for no apparent reason", "I am testing how .NET WebSockets work when the client can't process data from the server side fast enough. For this purpose, I wrote an application that sends data continuously to a WebSocket, but includes an artificial delay in the receive loop. As expected, once the TCP window and other buffers fill, the SendAsync calls start to take long to return. But after a few minutes, one of these exceptions is thrown by SendAsync:\n\n\n System.Net.HttpListenerException: The device does not recognize the command\n System.Net.HttpListenerException: The I/O operation has been aborted because of either a thread exit or an application request.\n\n\nWhat's weird is, that this only happens with certain message sizes and certain timing. When the client is allowed to read all data unrestricted, the connection is stable. Also, when the client is blocked completely and does not read at all, the connection stays open.\n\nExamining the data flow through Wireshark revealed that it is the server that is resetting the TCP connection while the client's TCP window is exhausted.\n\nI tried to follow this answer (.NET WebSockets forcibly closed despite keep-alive and activity on the connection) without success.

The data is essentially countries with long and lat. I don't know anything about spatial data, but I'm assuming it's responsible for the shapes of the countries on a rendered map.\n\nI also have a data frame called results that initially has 234 rows, also about countries and some additional data for each country.

[ "Possible to build a dynamic array of streamwriters in Powershell?", "I have a very large file I need to process (> 10 GB). Hence my use of StreamReader and StreamWriter. My file contains a financial series of market prices in CSV format like this:\n\nDate,Time,Open,High,Low,Close,UpVol,DownVol\n\nThe file contains years of data, and I want to create one file per year, and remove the last two columns. I have a script which does this if I pass in the Year as a parameter. I thought of calling this script multiple times, but it would have to read the very large file multiple times. So, I only want to read the file once, and stream the processed data out to different files dynamically line by line. Here's my Single-Year script:\n\nparam ( \n [String]$file=$(throw \"Supply a file name to convert\"),\n [String]$year\n );\n\n$extension = [System.IO.Path]::GetExtension($file);\n$outFile = $file.Substring(0, $file.LastIndexOf('.')) + \"-\" + $Year + $extension; \n\n$reader = [System.IO.File]::OpenText($file);\n$writer = New-Object System.IO.StreamWriter $outFile;\n$reader.ReadLine() &gt; $null # skip first line (old header)\n$writer.WriteLine(\"Date,Time,Open,High,Low,Close\"); # write required header\nwhile (($line = $reader.ReadLine()) -ne $null) {\n $data = $line.Split(\",\");\n if ($data[0] -match $year) {\n $writer.WriteLine($data[0] + \",\" + $data[1] + \",\" + $data[2] + \",\" + $data[3] + \",\" + $data[4] + \",\" + $data[5]);\n }\n}\n$reader.Close();\n$writer.Close();\n\n\nSo, I'm thinking is it possible to look at $data[0] (the date), find the year with something like this:\n\n$thisYear = $data[0].Split(\"/\")[2];\n\nand then dynamically create a StreamWriter for each year that's found? Should I create an array of StreamWriters? Snag is, I don't know how many years or which years are in the files before I read them. It has to be done \"on the fly\". If the file I am reading contains ten years of data, I would expect ten streamwriters to be created with ten extra files at the end with the respective year's data in it." ]

It does not seem to be very robust and it crashes with all sorts of socket errors as soon as a page takes a long time to load and the user navigates elsewhere while waiting. So I thought to replace it with Apache. \n\nThe problem is, my current code is a single program that first launches about ten threads to do stuff, for example set up ssh tunnels to remote servers and zmq connections to communicate with a database located there. Finally it enters run() loop to start the internal server. \n\nI followed all sorts of instructions and managed to get Apache service the initial page.

Is there any way to make that work with Apache with a reasonable amount of work? Can I have Apache just replace the run() part and have a running application, with which Apache communicates? My current app in a very simplified form (without data processing threads) is something like this:\n\ncomm=None\napp = Flask(__name__)\n\nclass CommsHandler(object):\n __init__(self):\n *Init communication links to external servers and databases*\n def request_data(self, request):\n *Use initialised links to request something*\n return result\n\[email protected](\"/\", methods=[\"GET\"]):\ndef mainpage():\n return render_template(\"main.html\")\n\[email protected](\"/foo\", methods=[\"GET\"]):\ndef foo():\n a=comm.request_data(\"xyzzy\")\n return render_template(\"foo.html\", data=a)\n\ncomm = CommsHandler()\n\napp.run()\n\n\nOr have I done this completely wrong? Now when I remove app.run and just import app class to wsgi script, I do get a response from the main page as it does not need reference to global variable comm. \n\n/foo does not work, as \"comm\" is an uninitialised variable.

I just never thought this would need to be exported to Apache or any other web server. \n\nSo the question is, can I launch this application somehow in a rc script at boot, set up its communication links and everyhing, and have Apache/wsgi just call function of the running application instead of launching a new one? \n\nHannu" ]

[ "What is the best way for customization of multiple TestExecutionListeners methods invoking for TestSuite?", "For optimizing purpose I need to customize TestExecutionListeners invoking logic\n\nIn my case I have one ApplicationContext and two types of tests:\n\n\nOnes which use WebDriver (let’s call it ObservableTest)\nOnes which use RestTemplate and JdbcTemplate (let’s call it ApiTest)\n\n\nEach type uses its own TestExecutionListener:\n\n\nObservableTest - ObservableTestListener\nApiTest - ApiTestListener\n\n\nBoth ObservableTestListener and ApiTestListener extend TestListener where prepareTestInstance() is defined\n\nObservableTestListener implements beforeTestClass() and afterTestClass() methods as well as ApiTestListener does\n\nI need combine test types above in one JUnit TestSuite in the next way:\n\n\nFor each test prepareTestInstance() is invoked\nAs soon as first ObservableTest is about to be instantiated, beforeTestClass() of ObservableTestListener is executed\nThe same with ApiTest\nafterTestClass() of ObservableTestListener is invoked when last ObservableTest is finished in current Suite\nThe same with ApiTest\n\n\nThings got even more complicated as each test may be run in one suite and in different ApplicationContexts (due to different profiles usage)\n\nI would be very grateful for any hint and digging direction to implement such logic properly\n\nI have two ideas so far:\n\n\nImplementing custom Runner (I'm not confident it is even possible)\nNotify TestContextManager somehow that particular method (beforeTestClass() or afterTestClass()) should or should not be invoked. I have a feeling that @BootstrapWith custom SpringClassRule should help me in that\n\n\nThanks!" ]
