I have an ngx-bootstrap accordion that closes the open panel each time I call data back from an API using a .subscribe() method. The content in the headers of the Accordion all change seamlessly with no apparent reload, but as the change of the content inside the accordion is controlled with a range slider it's very annoying to have to re-open the panel each time the rage slider is changed.
Is there anyway I can stop this from happening?

Answered 2020-Sep-18 at 10:12That's a common problem when working with Angular. Your content is updated so Angular has no choice but to destroy it from the dom, and create it again, losing track of the item.. Hopefully, solutions exist !

I'm working on a project to convert type-writer written War Diary notes into text, from PDF scans. I can successfully (maybe 90% with original non-re-sized file) extract the main text, which I crop first.
Reprex data: You could try this from the beginning with the image, or with the text I provide below.
My challenge is to maintain the "daily" structure of the text, which has 7 paragraphs or sections, one per day, and splitting by "\n" or "\n\n" isn't working exactly right.
I'm using a combination of pdftools/stringr/tesseract/magick for the project:
...ANSWER
Answered 2019-Oct-02 at 00:34An option would be to use preserve_interword_spaces in order to preserve the large amount of spacing between paragraphs. Then, you can use stringr to split on spaces of a certain amount or greater
QUESTION
Hi I have 3 streams of events I want to merge using Kafka Streams.
I can't find a simple solution to tackle the concurrency problem :
...ANSWER
Answered 2019-May-21 at 04:21I think a simple aggregate should do the trick. An aggregation performs the operation you described : 'KTable as lookup and destination'.
On every arriving record, the aggregation table is checked for matches. In case no match is found, the Initializer defined in the aggregation is used to produce a new initial record : documentation available here

Install recc
For tests, and executable called 'build_tests' is created. This executable is a 'compiler' with the test build process hard coded into it.
The recc executable is used to preprocess .i files from all of the .c files in the 'test' directory.
The recc executable is used to build .l2 files from all of the .i files in the 'test' directory.
The recc executable is used to build .l1 files for each test in the 'test' directory.
.l0.js files are created for each test in the 'test' directory.
Once all .l0.js files have been built, chrome is envoked directly from the makefile, and chrome is instructed to browse to a url served by localhost, which serves files in the test-api-endpoint directory. This page contains javascript that interacts with the test API to obtain a list of all available test cases, then run each test and submit the result in the API. The test result from running the compiled code in the javascript emulator is saved into the 'test' directory.
Each of the .c files in the 'test' are compiled using (your host compiler) into standard desktop executables.
The executables created using gcc are then run, and output is saved to the 'test' directory.
The saved output from javascript and gcc are diff'ed. If the diff is not empty, the test failed.
