list item highlighted but not the entire row My current fiddle is working fine apart from one thing. When I hover over the button I see the list displayed. Then when I hover over a list item the background changes colour which is all fine. However when the list item changes colour there is almost a box to the left of the item which is not highlighted and can't seem to get rid of it? .dropbtn { background-color: #9FACEC; color: white; padding: 16px; font-size: 16px; border: none; } .dropdown { position: relative; display: inline-block; } .dropdown-content { display: none; position: absolute; background-color: #f1f1f1; min-width: 160px; box-shadow: 0px 8px 16px 0px rgba(0,0,0,0.2); z-index: 1; } .dropdown-content li { color: black; padding: 12px 16px; text-decoration: none; display: block; } .dropdown-content li:hover {background-color: #ddd;} .dropdown:hover .dropdown-content {display: block;} .dropdown:hover .dro

individual components should be connected to the store instead of just a few, "Redux may not be as efficient out of the box when compared to other libraries. For maximum rendering performance in a React application, state should be stored in a normalized shape, many individual components should be connected to the store instead of just a few" I read this on https://redux.js.org/faq/performance The question is why "many individual components should be connected to the store instead of just a few" help improve performance ? I always try to minimize accessing to redux store by reduce connected Component , does it right ? Yes, example to avoid to re render a Parent component for refresh a Child component it is usefull to directely connect the Child ... and many other reasons – N.Safi Jul 2 at 14:22

Log Trace.WriteLine in Azure Our team has an ASP.NET Core Web Application which integrates Multisafepay payment provider (MSP). We use the .NET wrapper of MSP to communicate with the API of the payment provider. In some cases when we asking for the payment URL where the user can pay for his order we got an error code 9999 (unknown error). Mostly this happens after we restart our Web App in Azure or when it comes back from idle time. I checked out the code of the MSP wrapper. It has some Trace.WriteLine statement in its code right where the error 9999 occurs. Is there any way to log the content of the trace in Azure? I've tried almost everything. Modyfing the web.config, and adding trace listneres to it, turning on the Application Loggin and Log Stream in Azure, etc. but nothing worked.

How do you handle the serving of images for screens with different dpi? I have images with different dpi , How do you handle the serving of images for screens with different dpi? here is what I have so far. @media only screen and (-webkit-min-device-pixel-ratio: 1.5), only screen and (min--moz-device-pixel-ratio: 1.5), only screen and (-o-device-pixel-ratio: 3/2), only screen and (min-device-pixel-ratio: 1.5) { //high resolution images go here } Is this the right way of handling images with different dpi? 1 Answer 1 The best way to handle different image-sizes (responsive) in combination with retina is to use scrset/sizes, here you hand the browser information it needs to deside which is the best image to use. https://ericportis.com/posts/2014/srcset-sizes/ <img src="small.jpg" srcset="large.jpg 1024w, medium.jpg 640w, small.jpg 320w&q

Do Runtime Type Services (RTTS) use database to get data descriptions? Question Do methods like describe_by_data , get_ddic_field_list , get_components (of cl_abap_typedescr and similar), retrieve data from database or does it get generated on application server? describe_by_data get_ddic_field_list get_components cl_abap_typedescr I looked at those classes and all of the some methods (that populate cache, presumably) appear to pull data in non-standard ways ( METHOD ... BY KERNEL MODULE ... ) and others pull data from cache. I am wondering how it gets pulled if it is not cached. METHOD ... BY KERNEL MODULE ... Google didn't give me any concrete info on this topic either. Some context, in case details become relevant I've been looking into implementing dynamic select clauses generation for some generic classes (to replace asterisk for column-based processing in S/4HANA and hopefully reduce the strain on DB). Since most of those classes retrieve data into dictionary type stru

How to check if stored procedure returns data or not? I have a stored procedure GetLastRecordId() in SQL Server which returns the last record id in controller of ASP.NET MVC project. But the problem is that when there is no data in the table, it shows a result like below so I can't check against null: GetLastRecordId() My stored procedure: ALTER PROCEDURE [dbo].[GetLastRecordId] AS BEGIN SET NOCOUNT ON; SELECT CustomerCreditAppId, CompanyName FROM tblname WHERE CustomerCreditAppId = (SELECT MAX(CustomerCreditAppId) FROM tblname) END Expand the results view and re-upload your screenshot maybe? Also, copy/paste the stored procedure and add corresponding tag? – Rafalon Jul 2 at 14:01 I cannot see anything in this screenshot :-)

Do we really need to add spring boot starter web for spring boot admin clients? Version 1.5.4 was working fine without extra declaration of starter web in POM. When I upgraded to 2.0.1, I had to add starter web to POM to make it work. Without starter web, there is no error or no log related to registering the application. It's not documented anywhere as far as I know. Can anyone please confirm? can u post the exception which u were getting without the dependency? – Indraneel Bende 10 hours ago Hi @IndraneelBende , I did not get any error in logs.

How to flat map a dataframe with unequal lists? I have a data frame as follows- a | b | c [1] | [3,4,5,6] | [7,8,9,10] i need the output as a | b | c 1 3 7 1 4 8 1 5 9 1 6 10 Currently i am getting output as below upon using the following statement- cols=['a','b','c'] df.rdd.flatMap(lambda x: itertools.izip_longest(*[x[c] for c in cols])).toDF(cols) a | b | c 1 3 7 null 4 8 null 5 9 null 6 10 The number of columns are not fixed. If the solution is a generalized it would be helpful. 1 Answer 1 One option is to use itertools.repeat to repeat each array whose length is less than length of the longest array. itertools.repeat from itertools import izip_longest, repeat, chain cols = df.columns def zip_wit

Prolog simple recursion This is a really simple quesiton but I don't get it. insert(X, L, [X|L]). insert(X, [H|T], [H|T2]) :- insert(X, T, T2). We run it with insert(1, [2,3], L). insert(1, [2,3], L). When it's called the 1st insert produces (1, [2,3], [1|2,3]) > L = [1,2,3], then it looks at the second insert(1, [2|3], [2|T2]) // T2 is a variable im guessing.. and it calls insert(1, [3], T2) which calls the 1st insert again with insert(1, [3], [1|3]) > L = [1,3], which is not true, because it actually returns L = [2,1,3]. What am I missing about recursions? Syntax correction [1|[2,3]] not [1|2,3] and [2|[3]] not [2|3] . – lurker Jul 2 at 13:47 [1|[2,3]] [1|2,3] [2|[3]] [2|3] You neglected to unravel the full recursion in your second example. The call to insert(1, [2|[3]], L) matches the sec

Personalization of Carousel on AEM 6.3 I have a requirement where we need to personalize the carousel in the home page, based on the location from where the website is accessed. For this I have created required segments and activity and brand, and targeted to the carousel component. The issue I am facing here is that the /etc/cloudsettings/default/contexthub.kernel.js is loading after all the client libs in my project is loaded, so the carousel images are getting updated but not displayed in the form of slides, but one below the other. Is there any event which can be captured by js and then reload the owl-carousel.js? Could someone please suggest any fix for this?

cudart_static - when is it necessary? Since newer drivers ship with the CUDA runtime (I can choose 9.1 or 9.2 in the drivers download page) my question is: should my library (which uses a CUDA kernel internally) be shipped with -lcudart_static ? -lcudart_static I had issues launching kernels compiled with 9.2 on systems which used 9.1 CUDA drivers. What's the most 'compatible' way of ensuring my library will run everywhere a recent CUDA driver is installed? (I'm already compiling for a virtual architecture) 1 Answer 1 Since newer drivers ship with the CUDA runtime (I can choose 9.1 or 9.2 in the drivers download page) No, that's incorrect. That choice in the drivers download page is related to the fact that each CUDA version has a minimum required driver version associated with it. It does not mean that the driver ships with the CUDA runtime (stated another way, the driver does
