"Is it possible to generate a color?",
"I know there has already been posts on this, but I still don't quite get it.. I want to have a script that automatically generates a color code ({color:Lighter}) which would be a lighter version of {color:Links}. I would want the script to take the colorcode of {color:Links} use the hex code, (it has to be hex) and make it like 10 times lighter. Very close to white, but off white enough so that you can still see the color. Can someone please provide me with a code?"

"Nested tables in database",
"I am working on a project, that has multiple processes and each process has different data items to process. Data items (For different processes) have different columns (but always the same columns for the same process).\n\nAt first, I assumed that it would be fine to have a table for all of the processes and then, whenever a new process is created, another table with the item data could be created as well, but it turns out, that there would be a new process way to often to create new tables all the time. Then I was looking into nested tables but found out that there is no concept of the nested tables in MySQL. (I've heard that this could be done with MariaDB. Has anyone worked with it?)\n\nTo make it a bit more clear here is the current concept (columns and values here are only approximate to make the concept more clear):\n\nprocess_table:\n\nID | process_name | item_id | ...\n---------------------------------\n1 | some_process | 111 | ... \n2 | other_process| 222 | ... \n3 | third_process| 333 | ... \n4 | third_process| 444 | ...\n...\n\n\nitem_tables:\n\nitem_table_1:\nID | Column1 | Column2 | process_name | ...\n--------------------------------------\n111| val1 | val2 | some_process | ...\n...\n\nitem_table_2:\nID | Column4 | Column5 | process_name | ...\n--------------------------------------\n333| val1 | val2 | third_process| ...\n444| val3 | val4 | third_process| ...\n...\n\n\nSo then for each new process, there would be new item_table and for each process, it needs to have different column names, and in item table, the specific item would be linked to 'item_id' column in the process table.\n\nI think that the easiest solution (when creating new tables all the time is not an option) for this would be nested tables, where, in the process table, there could be another column, that would hold the item_table values and then those could have different columns based on the process itself.\n\nSo the big question is: Is there at least anything similar to nested tables or anything else in MySQL that would help me implement structure like this without creating new tables all the time, and if not, then maybe there are some tips or reviews about MariaDB? Maybe someone has already implemented nested tables with it (If that is possible at all)\n\nOne of the solutions would be to have one table for the 'item_table' and then have one column for all the different values for processes, that would be stored in JSON format for example, but this would make it a lot harder to read the table.\n\nFor example:\n\nitem_table:\nID | process_name | data\n--------------------------------------\n111| some_process | {values: {column1:val1,column2:val2,...}}"

"How to download a file from FTP and store it locally with Cordova?",
"I'm struggling for some days to do that. Without success.\n\nI've found two ways that I think reasonably to follow:\n\n1: Plugin cordova-sftp-plugin.\n\nI see that it is writted to deal with 'secure ftp', but why wouldn't work in an ordinary non secure ftp? Nothing was metioned about it.\n\nI've tried so, applying the 'Use Example' from the official page, the code fells in the success callback function, but when I list the local directory, nothing was changed! It gives me no clue about what goes wrong! In true, the software does not detect nothing wrong.\n\nBefore the previous steps, I did not forget to precautionally install and enable the 'cordova-plugin-file', 'cordova-plugin-file-transfer' and 'cordova-plugin-network-information' and to add the <uses-permission android:name=\"android.permission.WRITE_EXTERNAL_STORAGE\" /> in the AndroidManifest.xml. Tryied to save files in cordova.file.externalRootDirectory and cordova.file.externalRootDirectory + \"/Downloads/. Nothing worked.\n\n2. The macdonst FtpClient plugin.\n\nSearching for my issue, one of the first pages that appears is How to ftp a file over to a server from PhoneGap/webapp?, and beyond some further search I've found another one in a relatively old post mentioned the successful use this plugin in a Cordova application. So I can consider this plugin as a stable choice.\n\nThe problem with this method comes earlier: I coundn't even build the application after a manual installation proccess. May it is a problem in the manual installation proccess.\n\nThe official plugin documentation teachs to install it in a PhoneGap application, and not a Cordova. The steps was not replicable to Cordova, due to some differences in paths and configuration, and some others links also supports the plugin installation solely in Phonegap, not Cordova.\n\nI also tryied follow the steps in the http://antonylees.blogspot.com.br/2015/01/how-to-manually-add-cordova-plugins-to.html and Manually install Device plugin (and others) into cordova 3.0 to manually add the plugin. The steps in the first link also was not well replicable, and although the second one are more straitfoward, also does not solved the issue.\n\nBuilding it gives me a java error compilation. The first error output (what uses to cause all the following errors are):\n\nE:\\danilo\\Documentos\\projetos_cordova\\ftpDownload3\\platforms\\android\\src\\com\\phonegap\\plugins\\ftpclient\\FtpClient.java:27: \nerror: package org.apache.cordova.api does not exist\nimport org.apache.cordova.api.CallbackContext;\n\n\nVery strange. May I have to search for the org.apache.cordova.api jar file and put in the lib folder? Also, I did not forget to put the commons-net-2.2.jar in the project libs folder.\n\nCan anyone have some suggestion to succeed this? I just want to download a file through ftp protocol and save locally and so, if there's an alternative method to succeed, it will be appreciated too.\n\nThanks in advance."

"regex for N (1 to 3 digit) numbers in square brackets with commas+spaces between them",
"I'm going to try to phrase this clearly... (I'm pretty new at regex). I'm working on a PDF document, with a program called AutoBookmark (from Evermap). I'm trying to set it up to link numbered citations to numbered references in a bibliography.\n\nThe goal is to match each numbered citation within brackets, and return that number within brackets, alone. In other words, if I have [85], I'd just return [85]. If I have [85, 93], I'd return both [85] and [93]. If there are more numbers in brackets, up to N numbers, I'd return N of them (in brackets). If there is a range, i.e., [85-93], I only need to return the first. \n\nSo it seems to me I'm asking this: the number (1 to 3 digits), only if preceded by EITHER an opening bracket, OR another number followed by a comma and a space, but only if that number is preceded by an opening bracket OR by a number followed by a comma and a space, but only if... you get the picture. Iterate until you hit a bracket (then return the number) or a non-number, in which case, don't return the number.\nIs this something even reasonable to ask of a regular expression? Or, since I'm doing this in a PDF, must I do a Javascript routine? (which BTW, I also don't know how to do!)\nThanks! I know I'm a newbie at this, and I'm grateful for any thoughts."

The only problem I'm running into is that the service expects self-closing elements within an array argument, but the SoapHttpClientProtocol (which VS used as the inherited class when creating the web reference class from the wsdl) is sending empty elements instead. I've tested this using soapUI and verified that the service will accept self-closing elements within the array or a self-closing element with the name of the array (and thus no child elements), but throws an error when it receives empty elements.\n\nHow can I set the SOAP factory to use self-closing elements when no data are present?

"Using tags creatively",

This seems like overkill to me - clunky, lots of work to implement, and too 'fixed' given how rapidly the front-end design can change. \n\nWhat do you think is the best way to proceed with this - is there a design flaw with using tags for 'creative' purposes like this that I'm not considering?"

"jQuery ajax override global onSuccess handler",

This data is transformed within this method.\nAfter previous handler returns the transformed data, it's received by the local onSuccess handler which uses the data to add content to the page, etc.\n\n\nI'm aware of the existence of the Ajax events, but so AFAIK, it doesn't look that ajaxSuccess event will:\na) be called before the local success event\nb) have the modified data sent to the local event\n\nIn order to achieve something similar, I think I could use the global ajaxSend event to abort the current ajax request, create a wrapped one with the handlers I need, and then send the new wrapped request instead.

"Question regarding missing RemoveHandler in WPF application function",

We could move the viewmodel declaration to a more global level but this does not seem as clean.\n\nThe question is: is a RemoveHandler necessary in this scenario?

"Build insert query from array MySQL and PHP",
"I'm writing a small web service in PHP and I'm having a bit of trouble getting my head around the following scenario.\n\nMy plan is to be able to send an array of data to a function, which would then build a query for MySQL to run. In the array I plan for the key to be the column name, and the value to be the value going in to the columns.. i.e.\n\n$myData = array('userName'=>'foo','passWord'=>'bar');\n$myClass = new users();\n\n$myClass->addUser($myData);\n\n\nThen, in my function I currently have:\n\nfunction addUser($usrData){\n foreach($usrData as $col => $val){\n\n // This is where I'm stuck..\n\n }\n}\n\n\nBasically, I am wondering how I can separate the keys and values so that my query would become:\n\nINSERT INTO `myTable` (`userName`,`passWord`) VALUES ('foo','bar');\n\n\nI know I could probably do something like:\n\nfunction addUser($usrData){\n foreach($usrData as $col => $val){\n $cols .= \",\" . $col;\n $values .= \",'\".$val.\"'\";\n }\n}\n\n\nBut I thought there might be a more elegant solution.\n\nThis is probably something really simple, but I have never came across this before, so I would be grateful for any help and direction..\n\nThanks,\n\nDave"

"Looking for suggestions to get rid of inefficient for loop in raycasting",
"I am currently working on a project to measure the volume of objects on a production line in real time using 3D depth cameras. There will be obfuscation and worse or better angles and therefore we want to simulate different camera configurations before we build a rig and test it in production. We have a large number of CT scans of these objects and based on these we want to simulate different camera views. What we want to simulate is a pointcloud as would be generated by a camera in a given position.\n\nEvery method I have found traces one ray at a time and you have to loop over the rays in a python loop. This is the slow part and I am looking for a method to get rid of this python loop. My intuition is that there should be a GPU accelerated library that can do this very quickly but I haven’t been able to find it, I usually do segmentation and registration of CT scans not 3d graphics. Below is a bit of detail on what I have tried so far.\n\nI have a camera class. Of relevance for these calculations I have a source point self.pos and a plane of points I want to project to self.points_plane these are points in 3D space. So all the rays originate in self.pos and end at one of the elements in self.points_plane. My initial attempt was to use scipy.ndimage.map_coordinates: \n\nfor point in self.points_plane:\n dist = int(np.sqrt((self.pos[0]-point[0])**2+(self.pos[1]-point[1])**2+(self.pos[2]-point[2])**2))\n z_line = np.linspace(self.pos[0],point[0],dist)\n y_line = np.linspace(self.pos[1],point[1],dist)\n x_line = np.linspace(self.pos[2],point[2],dist)\n\n stack = ndimage.map_coordinates(array,np.vstack((z_line,y_line,x_line)),order=1,cval=-1000)\n # Hounsfield value check, air is -1000 and our objects are in the range -200:1000\n intersections = np.argwhere(stack > -500) \n if intersections.size > 0:\n point_cloud.append([z_line[intersections[0][0]],y_line[intersections [0][0]],x_line[intersections [0][0]]])\n\n\nIt works, and the result looks nice but it’s too slow and we would be finished simulating next year… CuPy is a CUDA implementation of numpy/scipy and this was the next attempt since all the needed methods existed. Map coordinates was quicker but the transfer to GPU and back was slow and we still have a python loop. Not really a significant improvement, code is almost identical to the non-CUDA code. \n\nI tried VTK.vtkOBBTree() and obbTree.IntersectWithLine() methods to see if this was a good solution and it is for small number of points. The IntersectWithLine method takes a starting and end point for each line and the checks for intersections with the obbTree generated from an STL file. The method is fast as long as we are not looping over too many points, at the scale we are working it would still take about a month to simulate the relevant data. \n\nfor point in self.points_plane:\n pointsVTKintersection = vtk.vtkPoints()\n obbTree.IntersectWithLine(self.pos, point,pointsVTKintersection,None)\n pointsVTKIntersectionData = pointsVTKintersection.GetData()\n noPointsVTKIntersection = pointsVTKIntersectionData.GetNumberOfTuples()\n\n if noPointsVTKIntersection > 0:\n point_c.append(pointsVTKIntersectionData.GetTuple3(0))\n self.point_cloud = np.array(point_c)\n\n\nAny recommendations on how I can get rid of this for loop, is there a lib that does this in parallel for multiple rays?"

"Find out what changed resources caused a workspace refresh/rebuild in Eclipse with Buildship",
"Is there a way to get more detailed logging output from the Eclipse platform or the Buildship plugin (or even through the Gradle API itself) with regards to what caused a project to be rebuilt?\n\nContext:\n\nWe are currently migrating from Eclipse Mars (with Spring Gradle plugin) to Eclipse Photon (with Gradle Buildship plugin). One problem we encounter with the new version is that it ends up rebuilding large parts of the workspace every time we open Eclipse, which may take several minutes in large projects. Refresh workspace on startup is disabled in the Eclipse preferences. Setting Max simultaneous project builds to a higher value and Max iterations when building with cycles to a lower value than the defaults help mitigate the problem a bit by speeding up that initial rebuilt, but in the end it only works around the actual issue.\n\nWe did not have these problems in the old version and this behavior seems weird to me. After fully building the workspace, closing Eclipse and reopening it, I would expect that no resources changed and there is no need for a rebuild.\n\nWhile we do have quite a few custom Gradle plugins and tasks, there are no obvious offenders, like tasks that generate sources. I do not want to fully dismiss the possibility that something we customized is messing with a file while evaluating the Gradle projects, though.\n\nHence why getting more information about why the IDE/plugin believes that the project requires rebuilding would be really appreciated to get a starting lead.\n\nThe only setting I've found so far is eclipse.log.level, but that already defaults to ALL."

This is what I've tried without succes.\n\n<dd class=\"accordion-navigation\">\n <a href=\"#panel1a\" class=\"tab-table\" role=\"tab\" id=\"panel1a-heading\" aria-controls=\"panel1a\" id=\"first-tab-accordion\">Subastas Activas\n <i class=\"fa fa-chevron-down styled-tab-icon arrow-content-hidden\" id=\"arrow-content-hidden-first\"></i>\n <i class=\"fa fa-chevron-up styled-tab-icon arrow-content-shown\" id=\"arrow-content-shown-first\"></i>\n </a>\n // More stuff...\n</dd>\n\n\nThis is the css\n\n.arrow-content-hidden {\n }\n\n.arrow-content-shown {\n display: none;\n}\n\n\nThis is the js\n\n<script>\n\nfunction toggle() {\n var arrowTabDown = document.getElementById(\"arrow-content-hidden-first\");\n var arrowTabUp = document.getElementById(\"arrow-content-shown-first\");\n if (arrowTabDown.style[\"display\"] == 'none') {\n arrowTabDown.style[\"display\"] = 'block';\n arrowTabUp.style[\"display\"] = 'none';\n } else {\n arrowTabDown.style[\"display\"] = 'none';\n arrowTabUp.style[\"display\"] = 'block';\n }\n};\n\ndocument.getElementById(\"first-tab-accordion\").addEventListener(\"click\", toggle, false);\n</script>"

"SQL to get the one to many mapping (like reverse CASE WHEN THEN END or decode in Oracle)",

".NET AutoComplete DropDownList or TextBox on Mobile Web Browser?",
"I'm trying to build an AutoComplete DropDown List that will work on a Mobile Browser (Pocket IE, Opera Mobile, etc.) So for example, if I had one for US States, after typing in 'Ma', I'd expect to see 'Maine', 'Maryland', 'Massacusetts' as selectable options\n\nI've been able to build one for a traditional browser with no issues, using both 3rd party tools (Telerik RadControls) and using basic AJAX components (scriptmanager, textbox, and autocompleteextender), but haven't had any success on a mobile platform.\n\nWhat seems to be the problem in my opinion is the mobile framework seems to be limited when it comes to javascript and AJAX support.\n\nAm I missing something? Has anyone had any success with a project like this before?\n\nThanks for any suggestions.\n\n~Jim"

"Makefile dependency without declaring a rule?",
