QUESTION
I'm using a MainActivity that links to many activies. The first time that you push on a button from the MainActivity to go to another activity, it takes 2-3 seconds to load. After the first time, you can do everything by loading activities in less than 1 second (as I expected).
I don't know how to solve this, since I'm new in Android Studio and in the stack trace there isn't something that could make me understand the problem.
Here is the stack trace:
...ANSWER
Answered 2021-Jan-23 at 14:24In the above stacktrace, please read this warning:
2021-01-23 00:56:10.168 31264-31264/it.iovara.trainassistant I/Choreographer: Skipped 93 frames! The application may be doing too much work on its main thread.
This means that, you need to refactor your code such to ensure that minimal work is being done on main thread.
It seems that, your Main Activity OR the logic behind the 'Button` which navigates to another activity consist of long operations.
If you have any heavy work/calculations in your code then use background thread.
Cleanup the code in your both activity and button click logic and then your transition will be quick and smooth.

I'm trying to compile some code using glew.h and glext.h. Here's a minimal example:
...ANSWER
Answered 2020-Nov-25 at 17:39I'm trying to compile some code using glew.h and glext.h.
Don't do that. These are two different tools that both do the same thing. They are not intended to be compatible with each other, and neither is expected to work in the presence of the other (in the same source file).
You are either using GLEW or you're manually loading function pointers through glext.h. Pick one.

if you want to store the binary value, you only need 16 bytes, but they must for CHAR(16) FOR BIT DATA
QUESTION
I have a wide table with 161 variables that I would like to transform into a narrow table with only 13 variables. As far as I can tell, I cannot use pivot_longer because I need to input an additional column for Year, and then only select certain columns from the wide table for each row.
I started with a blank data frame:
...ANSWER
Answered 2020-Feb-09 at 01:12The difficulty is that the year is encoded in the column names in different ways, some columns use a 4 digit year, some columns a 2 digit year. (In addition, the names of the last 3 columns of subset seem to be misspelled at all.)
The year naming issue can be solved by reshaping all variables to long format, separating and completing the year from the variable names and then reshaping to the requested format:

QUESTION
I have a simple experiment (here is some made-up data) with 3 locations ("loc"), blocks within locations ("block"), a set of 8 treatments ("treat), and a response variable ("response"). An exponential plateau function was adjusted to this data (response as a function of treat) and the NLME function was used to analyze the whole experiment using mixed models. The parameters of the exponential plateau function is considered the fixed part while loc and block are random.
My problem is with the prediction of the model. I am not able to get the prediction for the response to the treatments at the loc level. I am able to get it to the population level (fixed effect), but got all NAs for the prediction when try to do it a the loc level. Is there something wrong with the way I set the "levels= " option?
Here is my made up data
...ANSWER
Answered 2019-Sep-03 at 21:20Not seeing any NA's. Can you show the codes and sufficient output to document your issues? (I was instead using levels=0:2 and looking at str(pframe.lp) and then getting this from summary(pframe.lp$yield.exp$predict.loc):
QUESTION
I'm new to Rcpp and RcppParallel. I'm trying to use RcppParallel to optimize my R code and now I'm making some toy codes for studying them. Now I made a RcppParallel code and the result is different from what I thought. Result changes whenever I try the function.
Here is my code
...ANSWER
Answered 2019-May-14 at 14:34You have a race condition (also called data race in this case) in our code, since all the threads are writing to the same two element vector tmp. However, incrementing a value needs three steps:
- reading the value
- incrementing the read value
- writing back the incremented value
If all threads do this in parallel without locking, one thread will write back between another thread reading and writing, throwing away the increment done by the first thread.
One solution would be to use per-thread output variables which are collected after wards in serial code. It might also make sense to look into RcppParallel::parallelReduce, since what you are trying to do is a reduce type operation.

QUESTION
I have a list of JSON responses that I want to parse before putting it into a DataFrame.
In my list of 15,000 responses I want to remove those that do not have a certain key in it.
What I have so far seems to be playing funny business with the looping after I delete an element and I'm not sure why.
If I run the below - it correctly finds 3 matches of the 15k that should be deleted.
...ANSWER
Answered 2019-Jan-17 at 03:31You can use filter this would be faster and you won't be editing the data while looping through it
QUESTION
I have used the requests module before, today I try to send a get request to a server to fetch a JSON data with the QtNetwork module. Everything is Ok, but the reply is always null. I searched the case but with a bit of bad luck, hadn't found any successful solution.
The code is as follows：
ANSWER
Answered 2019-Jan-16 at 06:27The requests in Qt are asynchronous unlike the library requests, that is, they will be done when synchronous tasks are finished, so when you ask for the data the request has not been made yet and therefore the data will be empty, and you are assuming that they are synchronous, a Possible solution is to use a QEventLoop.

Install 12306
PHP requires the Visual C runtime (CRT). The Microsoft Visual C++ Redistributable for Visual Studio 2019 is suitable for all these PHP versions, see visualstudio.microsoft.com. You MUST download the x86 CRT for PHP x86 builds and the x64 CRT for PHP x64 builds. The CRT installer supports the /quiet and /norestart command-line switches, so you can also script it.
