QUESTION
I have file txt with format like this
...ANSWER
Answered 2021-Jun-15 at 21:31You add each line to the variable list_Siswa
. So for instance the first element of list_Siswa
will be ["Nama"," John"]
, and so data_Siswa[0]
equals "Nama"
and data_Siswa[1]
equals " John"
. Then data_Siswa[2]
throws an error, because there is no such element in the array.
The code isn't smart enough to see Nama: John
and assume the following lines are grades that should be associated with John. If you want that, you'll have to do it yourself.
QUESTION
I'm currently learning HTML, CSS, and JavaScipt. I'm trying to make a basic project, but I'm having problems with adding a new image on the new card. When I click on the 'add item' button, I create a new card with image. However, when I add another card for the second time, my image from the first card that I created will disappear. Can someone help me on how to fix this solution. Thank you.
...ANSWER
Answered 2021-Jun-15 at 19:05Rather than using two different function, one for adding card image and one for card content, try combining both of them.. here use the code for your reference.

I have a sql table which field are qustionid, question, answer, message-type . i am generate dynamic label text through c#. how to compare message-type field value on c# if else condition.
my code is-
...ANSWER
Answered 2021-Jun-15 at 19:03To compare, you first need to put your condition inside while (reader.Read()){} . then add the column number of your table to reader[].toString() in your if-else condition. learn more about Database adapters before you do these!

QUESTION
I'm currently building an etl pipeline that pulls data from large oracle tables to mongodb, i want to know exactly what's the difference between JdbcCursor Item reader and Jdbc Paging item reader. which one of them is best suited for large tables. are they thread safe ?
...ANSWER
Answered 2021-Jun-15 at 09:05JdbcCursorItemReader
uses a JDBC cursor (java.sql.ResultSet
) to stream results from the database and is not thread-safe.
JdbcPagingItemReader
reads items in pages of a configurable size and is thread-safe.

QUESTION
Using Spring Batch, I have to write in two different table, but using the same ItemReader.
I can't figure out how to use one ItemReader and a CompositeItemWriter.
Here's the JobConfiguration :
...ANSWER
Answered 2021-Jun-15 at 06:57This is because your ItemProcessorSurveillance
implements two interfaces: ItemProcessor
and StepExecutionListener
but is only registered as an ItemProcessor
in the step. It should also be registered as a listener so that beforeStep
is called when appropriate to set the stepExecution
field.
QUESTION
We are programmatically creating PDF using our in house lib (C++) by adding all the required objects so that PDF readers can render them properly. Currently we are enhancing the lib to support digital signatures in PDF. Our users will use USB token or Windows certificates to sign the PDF. On studying raw PDF file with digital signature, we were able to make sense of all the objects except for the contents of Sig type object.
...ANSWER
Answered 2021-Jun-10 at 16:48Ok, the signature container is embedded correctly.
But there are issues with the signature container itself:
Both in the
SignedData.digestAlgorithms
collection and in theSignerInfo.digestAlgorithm
value you have used the OID of SHA1withRSA, but that is a full signature algorithm, not the mere digest algorithm SHA1 expected there.Then the SHA1 hash of the signed bytes is BB78A402F7A537A34D6892B83881266501A691A8 but the hash you signed is 90E28B8A0D8E48691DAFE2BA10A4761FFFDCCD3D. This might be because you hash buffer2 and
buffer2 has empty contents data (/Contents <>)
The hex string delimiters '<' and '>' also belong to the contents value and, therefore, must also be removed in buffer2.
Furthermore, your signature is very weak:
- It uses SHA1 as hash algorithm. SHA1 meanwhile has been recognized as too weak a hash algorithm for document signatures.
- It doesn't use signed attributes, neither the ESS signing certificate nor the algorithm identifier protection attribute. Many validation policies require such special attributes.
QUESTION
I'm trying to understand best practices for Golang concurrency. I read O'Reilly's book on Go's concurrency and then came back to the Golang Codewalks, specifically this example:
https://golang.org/doc/codewalk/sharemem/
This is the code I was hoping to review with you in order to learn a little bit more about Go. My first impression is that this code is breaking some best practices. This is of course my (very) unexperienced opinion and I wanted to discuss and gain some insight on the process. This isn't about who's right or wrong, please be nice, I just want to share my views and get some feedback on them. Maybe this discussion will help other people see why I'm wrong and teach them something.
I'm fully aware that the purpose of this code is to teach beginners, not to be perfect code.
Issue 1 - No Goroutine cleanup logic
...ANSWER
Answered 2021-Jun-15 at 02:48It is the
main
method, so there is no need to cleanup. Whenmain
returns, the program exits. If this wasn't themain
, then you would be correct.There is no best practice that fits all use cases. The code you show here is a very common pattern. The function creates a goroutine, and returns a channel so that others can communicate with that goroutine. There is no rule that governs how channels must be created. There is no way to terminate that goroutine though. One use case this pattern fits well is reading a large resultset from a database. The channel allows streaming data as it is read from the database. In that case usually there are other means of terminating the goroutine though, like passing a context.
Again, there are no hard rules on how channels should be created/closed. A channel can be left open, and it will be garbage collected when it is no longer used. If the use case demands so, the channel can be left open indefinitely, and the scenario you worry about will never happen.
