"React slick height issue when ading slick items dynamically",
"I am using the react-slick slider to display a set of images. after the user crosses some slide position I am calling another API and appending the new results with the existing results using old.concat(new) stored in component state. Each time when the API is called, the slider displays 2 rows(its height is changed) and then adjust its height again.\nOnce the API data is added to the array, is there is a glitch that disturbs the slider and then fixes after few seconds? How do I fix this issue?\nI created codesandbox to replicate the issue here: https://codesandbox.io/s/react-slick-playground-forked-ub5fy"

"Google Chart - Timelines: Scaling Axis",
"I'm trying to create a chart using Google's Timeline that shows activity over the last 7 days, and I'm running into problems with scaling the x-axis. \n\nThe chart is always trying to auto-scale to the data, which ruins the consistency I'd like to incorporate. I want the right side of the graph to be today's date, and the left side to be seven days before today's date.\n\nI can't seem to find anything for fixing the x-axis in the documentation for Timelines or even Visualization in general, but I have to believe a charting library has the ability to configure its own axes. Does anyone have a solution that works?\n\nA possible workaround I have is creating two data points -- one for today and one for today-7 -- and add them to the graph. This fixes the scaling problem, but now my graph has two arbitrary data points on it. (I know it's technically a separate question, but if anyone knows how to hide these two data points while still maintaining the fixed axis scale that'd be a win!)\n\nHere's what my graph looks like using just the raw data (notice the axis -- I would like this to be last 7 days):\n\nAnd here's what it looks like with my two 'faked' data points:\n\nEDIT: I have tried using the viewWindow.max and viewWindow.min properties, but it doesn't seem to be working."

"Trying to use jQuery, Clone and multiplication function",

Sorry if this is a bit over-detailed!\n\nI have a table which has title, description, qty, price and total in it. The user can use autocomplete on the product field to fetch the title’s description and price. At the same time, I have an ‘add row’ function using clone and I’m trying to use another function to multiply the qty and price if either are changed. So far, I have the following: \n\nCode for adding new row to table:\n\nvar $table;\n$(function() {\n $table=$('#invoiceitems'); \n var $existRow=$table.find('tr').eq(1);\n bindAutoComplete($existRow);\n});\n\nfunction addRow(){\n var $row=$table.find('tr:last').clone();\n var $input=$row.find('input:first');\n $row.find('input').val(\"\");\n $row.find('#product_description').val(\"\");\n $table.append($row);\n bindAutoComplete($row);\n $input.focus();\n}\n\n\nCode for AutoComplete:\n\nfunction bindAutoComplete($row){\n $row.find(\".product_title\").autocomplete(products, {\n width: 380,\n matchContains: \"word\",\n formatItem: function(row) {\n return row.title;\n }\n });\n $row.find('.product_title').result(function(event, data) {\n $row.closest('.product_description').val(data.description);\n $row.find('.product_price').val(data.price);\n $row.find('.qty').val(\"1\");\n });\n}\n\n\nCode for multiplying price and qty:\n\n$(document).ready(function() { \n$(\".qty, .product_price\").keyup(function() {\n var $row = $(this).closest(\"tr\"),\n price = $row.find(\".product_price\").val();\n qty = $row.find(\".qty\").val();\n $row.find(\".line_total\").text(qty * price);\n});\n\n\nAt the moment, the AutoComplete and clone work fine however the multiplication for the qty and price only works on the first row and now on any new rows that are added. If I replace clone(); with clone(true); then the multiplication works however the AutoComplete does’t work properly as it updates the price on all previous rows when you use it.\n\nI am not very good with JS and jQuery so I am hoping this is a simple mistake to correct?\n\nMany thanks!"

"I'm looking for a method or possibly a philosophical approach for how to do something like GNU Make within python. Currently, we utilize makefiles to execute processing because the makefiles are extremely good at parallel runs with changing single option: -j x.

I want that same power and flexibility in python, but I don't see it.\n\nAs an example:\n\nall: dependency_a dependency_b dependency_c\n\ndependency_a: dependency_d\n stuff\n\ndependency_b: dependency_d\n stuff\n\ndependency_c: dependency_e\n stuff\n\ndependency_d: dependency_f\n stuff\n\ndependency_e:\n stuff\n\ndependency_f:\n stuff\n\n\nIf we do a standard single thread operation (-j 1), the order of operation might be:\n\ndependency_f -> dependency_d -> dependency_a -> dependency_b -> dependency_e \\\n -> dependency_c\n\n\nFor two threads (-j 2), we might see:\n\n1: dependency_f -> dependency_d -> dependency_a -> dependency_b\n\n2: dependency_e -> dependency_c\n\n\nDoes anyone have any suggestions on either a package already built or an approach?

"Im trying to implement a machine learning project that bases on Pixel-Rnn paper Link, and i'm having some problems to understand how to implement some things.\nThe model in the paper is\n\n7x7 conv mask A\nmultiple residual blocks conv 3x3 mask B\n2 Layers of ReLU followed by 1x1 conv Mask B\n\nI didn't understand the differences between Mask A and Mask B and how to implement them.\nalso, is there any residual block class to use in tensorflow library? if not how can i implement it?\nanother problem that i have is that i don't know how to implement the image generator of occured images.\nfor exmaple:\ni've tried to load data(image of size (28,28)) of numbers from MNIST dataset, then all the pixels from row above 13 i reset them to 0.\n(x1, _), (y1, _) = keras.datasets.mnist.load_data()\n\nafter i load the data i display the 4 images.\nf, axarr = plt.subplots(4,1) \naxarr[0].imshow(x1[0])\naxarr[1].imshow(x1[1])\naxarr[2].imshow(x1[2])\naxarr[3].imshow(x1[3])\n\nnow i reset some of the pixel to make them occured images.\nfor i in range(4):\n x1[i, 13:] = 0\n\nand now im stuck.\nbased on the paper i need to generate an image pixel by pixel using this - the probability formula\nwhich assign a probability p(x) to each image x formed of nxn pixels.\nI'm having hard time to understand how to work with generating problems in machine learning.\nIn the end i need to built a project that gets occured images and predicts them.\nHere is an example"

"Is Loosely Coupled on MVVM even posible?",
"I'm currently working on my first MVVM application using Caliburn.Micro. If understand correctly the concept of Loosely Coupled, I must be able to extract every class of my project, isolated it on a blank solution, and it must compile without problems because there is no direct reference to others classes, right?\n\nSo my question is this: \n\nWhere is the place to create the viewmodels for distinct views and mantain the loosely coupled model?\n\nI ask this because many examples on the web do something like this:\n\npublic class ShellViewModel : Conductor<IScreen>.Collection.OneActive { \nint count = 1; \n\npublic void OpenTab() { \n ActivateItem(new TabViewModel { \n DisplayName = \"Tab \" + count++ \n }); \n} \n} \n\n\nWhere TabViewModel is the viewmodel for the desired view. But here, shellviewmodel is tightly coupled to TabViewModel\n\nOther option i've try is to create some sort of menu class like this:\n\nclass MenuItem\n{\n public string Title { get; set; }\n public Type ViewType { get; set; }\n}\n\n\nand use it like this:\n\nnew MenuItem(){Title=\"My menu\",ViewType=typeof(ProductosViewModel)}\n\n\nAnd use a generic creation procedure, but again this class is coupled with ProductosViewModel.\n\nSo what other options do i have? Or should i forget about strict loosely coupled?\nThank you!"

"How do I organise pure QML projects for reusability?",
"I have a QML project that works fine when it's all in the same directory. There's a main.qml with a main.cpp containing the usual:\n\nQQmlApplicationEngine engine;\nengine.load(QUrl(QStringLiteral(\"qrc:/main.qml\")));\n\n\nThere is also my custom component, in pure QML, MyComponent.qml.\n\nWhen it is contained within a single project, it works perfectly. But now I want to think about reusability.\n\nI want to have separate main()s for the demo (what's there now), unit testing and usability testing. I want to be able to run these independently of each other.\n\nI also want to use MyComponent.qml without any of these main()s in other projects (that's the whole point!).\n\nI am not too hung up on the structure here, I just want the demo code to be separate from the widget code and to have a reusable widget.\n\nWhat do I need to do to achieve this?\n\nI've read How to package custom controls in QML?\n but the answer is light on detail. I can create the appropriate files for an Identified Module, but how do my separate projects actually access and incorporate them?\n\nI tried to arrange things as sub-projects, but didn't get very far. If I create a widget sub-project as a library project, I have this .pro file:\n\nTEMPLATE = lib\n\nTARGET = widget-lib\n\nQT += core quick qml\nCONFIG += c++11 plugin\n\nDISTFILES += \\\n MyComponent.qml\n\n\nThe project then fails to build because there's no actual library or entry point or, in fact, any code at all:\n\nLINK : error LNK2001: unresolved external symbol __DllMainCRTStartup@12\n\n\ndebug\\widget-lib.dll : fatal error LNK1120: 1 unresolved externals\n\nThe only other project type on offer in Qt Creator is a QML/C++ plugin, but since I have no C++ code in my actual component, that doesn't seem applicable.\n\nAdding the MyComponent.qml file to a demo sub-project also fails. With this QRC file:\n\n<RCC>\n <qresource prefix=\"/\">\n <file>main.qml</file>\n <file>../widget/MyComponent.qml</file>\n </qresource>\n</RCC>\n\n\n...the built demo project can't find MyComponent.qml because ../widget/ doesn't exist in the build output path.\n\nAdding the widget sub-project as a library also fails because there's no actual shared library to link against, so demo can't be built.\n\nI've read Module Definition qmldir Files, but it's all about how to create the file, and has nothing on how to use it.\n\nHow do I actually reuse a \"reusable QML component\"? How do I use the component itself in other projects, or have multiple mini-projects for testing the component itself? And how do I achieve this without just copy-pasting the component QML file into every project that needs it?"

"My SQL Using temporary tables with PHP without mysql_pconnect",
"I want to use temporary tables in my PHP code. It is a form that will be mailed. I do use session variables and arrays but some data filled in must be stored in a table format and the user must be able to delete entries in case of typos etc. doing this with arrays could work (not sure) but I'm kinda new at the php and using tables seems so much simpler. My problem is that using mysql_connect creates the table and adds the line of data but when i add my 2nd line it drops table and create it again... Using mysql_pconnect works by not dropping the table but creates more than on instance of the table at times and deleting entry's? what a mess! How can I best use temporary tables and not have them droped when my page refreshes? not using temporary tables may cause other issues if the user closes the page and leaving the table in the database."

"How does Google Analytics filters duplicate site entrances",
"We are implementing a native analytics system and want to apply the same tracking principles Google Analytics uses.

"Hive to HFile creation issue: MapR",
"I've been working on a small task of converting and loading hive data to HFiles in HBase; framework MapR. Using bulkload I'm loading the data after conversion in HFiles. There isn't any issue with conversion, the conversion is going fine. The only issue I'm facing is MR job failure as and when the size of hive data increases. The job fails because of virtual memory getting filled up. The job breaks if the hive data size limit crosses 10Gigs.\n\nAll data is moved into single region server instead getting distributed on multiple region servers; it's a 10 node cluster I'm working on. It seems there is hbase hotspotting. \n\nI've tried splitting the regions in multiples(NUMREGIONS => 256) and distributing the load equally (SPLITALGO => 'UniformSplit') among the regions. But it doesn't resolve the issue.\nAnybody got any idea how to resolve this hotspotting issue?? \n\nRegards,\nAdil"
