QUESTION
I have a Micronaut application running with the below configuration:

Answered 2021-Jun-13 at 09:19It is because you are starting another server by ApplicationContext.run(EmbeddedServer.class)
.
You don't need it. It is enough to inject HttpClient
into your class by constructor:

QUESTION
We have thousands of structured filenames stored in our database, and unfortunately many hundreds have been manually altered to names that do not follow our naming convention. Using regex, I'm trying to match the correct file names in order to identify all the misnamed ones. The files are all relative to a meeting agenda, and use the date, meeting type, Agenda Item#, and description in the name.
Our naming convention is yyyymmdd_aa[_bbb]_ccccc.pdf
where:
- yyyymmdd is a date (and may optionally use underscores such as yyyy_mm_dd)
- aa is a 2-3 character Meeting Type code
- bbb is an optional Agenda Item
- ccccc is a freeform variable length description of the file (alphanumeric only)
Example filenames:
...ANSWER
Answered 2021-Jun-15 at 17:46The optional identifier ?
is for the last thing, either a characters or group. So the expression ([a-z0-9]{1,3})_?
makes the underscore optional, but not the preceding group. The solution is to move the underscore into the parenthesis.
QUESTION
I am saving data in my SQL for my school homework
I don't want to update all that data one by one because it is too much would definitely end up finishing it up in the morning.
So I want to automatically update the data when I will modify it
as an example, if the sequence of the data is 1, 2, 3, 4, 5, .... and so on.
If add a data should on the place of 2nd position so the serial number of 2nd will automatically get updated to 3rd and 3rd to fourth and so on.
Hope I defined well 😅😅.
Thanks for your help.... have a nice day :)
...ANSWER
Answered 2021-Jun-15 at 15:23There's no way to insert and automatically push all the other sequence numbers up. You need to do that explicitly.
QUESTION
I am coding a room booking system using combination of Google forms and Google calendar.
When there is a new booking order:
- An event will be automatically created on the selected calendar.
- An edit response URL will also be generated automatically and put in column 10 of the spreadsheet in the same row where the form answer was inserted.
ANSWER
Answered 2021-Jun-15 at 10:43Finally I found one way to retrieve the edited row by using e.range method. So basically I created another sheet inside the same spreadsheet. When there is a new submission, it will automatically copy the new submission to the second sheet. And when there is an edited submission, it will go through the copy sheet to find the edited row, and then edit it (as well as the calendar). Credit to Tedinoz

QUESTION
I'm implementing a simple task queue using redis in Rust, but am struggling to deserialize the returned values from redis into my custom types.
In total I thought of 3 approches:
- Deserializing using serde-redis
- Manually implementing the
FromRedisValue
trait - Serializing to String using serde-json > sending as string > then deserializing from string
The 3rd approach worked but feels artificial. I'd like to figure out either 1 or 2, both of which I'm failing at.
Approach 1 - serde-redisI have a simple Task definition:
...ANSWER
Answered 2021-Jun-15 at 09:55Redis doesn't define structured serialization formats. It mostly store strings and integers. So you have to choose or define your format for your struct.
A popular one is JSON, as you noticed, but if you just want to (de)serialize simple pairs of (id, description), it's not very readable nor convenient.
In such a case, you can define your own format, for example the id and the description with a dash in between:
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.

I am working on a dataframe and I want to group the data for an hour into 4 different slots of 15 mins,
0-15 - 1st slot 15-30 - 2nd slot 30-45 - 3rd slot 45-00(or 60) - 4th slot
I am not even able to think, how to go forward with this
I tried extracting hours, minutes and seconds from the time, but what to do now?

QUESTION
The task is to build an accurate price calculator which accounts for a sales price based on quantity. I've built a gross price calculator using compiledCart.reduce() method, (below) however I can't figure out how to add the sales functionality.
If the user buys 1 Candy, the price is $3.97, if the user buys 2, the price is $5.00. If the user buys 3, then first two are $5.00 and the 3rd is $3.97. Same thing if the user buys 5. The first 4 are $10 and the 5th one is $3.97
My compiledCart variable looks like this:
...ANSWER
Answered 2021-Jun-15 at 05:53if the quantity is greater than 2 then:
divide the quantity by 2 and multiply by salesPrice
