QUESTION
Giving a bit of context. I'm using c++17. I'm using pointer T* data
because this will interop with cuda code. I'm trying write a parallel version (on CPU) of a histogram creator. The sequential version:
ANSWER
Answered 2021-Jun-16 at 00:46The issue you are having has nothing to do with templates. You cannot invoke std::async()
on a member function without binding it to an instance. Wrapping the call in a lambda does the trick.
Here's an example:
QUESTION
First time actually using anything to do with swing - sorry for the poor code and crude visuals!
Using swing for a massively over-complicated password checker school project, and when I came to loading in a JMenuBar, it doesn't render properly the first time. Once I run through one of the options first, it reloads correctly, but the first time it comes out like this:
First render attempt
But after I run one of the methods, either by clicking one of the buttons that I added to check if it was just the JFrame that was broken or using one of the broken menu options, it reloads correctly, but has a little grey bar above where the JMenuBar actually renders: Post-method render
The code for the visuals is as follows:

Answered 2021-Jun-15 at 18:29You should separate creating your menu from your content. Please review the following example. I decoupled your menu, component, and event logic into meaningful phases.

I have updated IntelliJ Idea Ultimate and scala plugin, it's working ok so far with sbt to build some projects.
Using a scala worksheet in REPL Interactive mode, I put in some code from a course lecture,

.
This way the 2 def
s that depends on each other will be available at the same time.
IntelliJ worksheets do not like such definitions as they are "evaluated" one by one. You cannot define 2 depending on one the other at the top-level, they need to be encapsulated.

I have to do an exercise were I got h.264 video sender host, h.264 video receiver (with background traffic receiver) host, and a background traffic generator host. All of these three are on different ip subnet connected to P4 controller.
...ANSWER
Answered 2021-Jun-15 at 17:48Yes I can see what you mean, I have done this integration before you only forget the priority statement otherwise should run well, please add this to your code;
after

QUESTION
I have a generator object, that loads quite big amount of data and hogs the I/O of the system. The data is too big to fit into memory all at once, hence the use of generator. And I have a consumer that all of the CPU to process the data yielded by generator. It does not consume much of other resources. Is it possible to interleave these tasks using threads?
For example I'd guess it is possible to run the simplified code below in 11 seconds.
...ANSWER
Answered 2021-Jun-15 at 16:02Send your data to separate processes. I used concurrent.futures because I like the simple interface.
This runs in about 11 seconds on my computer.
QUESTION
I am trying to use JOOQ code generation from JPA Entity. I have already created a dedicated maven module where the code will be generated which has dependency on a module containing all entities as well code generation plugin with of jooq.
To add more clarify on project structure, here are the modules:(The names are made up but the structure reflects the current project i am working on)
...ANSWER
Answered 2021-Jun-02 at 07:53I'm assuming you have missing dependencies on your code generation class path. Once you update your question, I'll update my answer.
Regarding jOOQ code generation support for@TypeDef
etc.
jOOQ won't support your generated composite types in generated code out of the box, you'll still have to add forced type configurations for that, possibly embeddable type configurations:
- https://www.jooq.org/doc/latest/manual/code-generation/codegen-advanced/codegen-config-database/codegen-database-forced-types/
- https://www.jooq.org/doc/latest/manual/code-generation/codegen-embeddable-types/
Note that the JPADatabase
offers a quick win by integrating with simple JPA defined schemas very quickly. It has its caveats. For best results, I recommend going DDL first (and generate both jOOQ code and JPA model from that), because it will be much easier to put your schema change management under version control, e.g. via Flyway or Liquibase.

QUESTION
I want to encrypt files fore secure storage, but the problem is, I don't know how to store the key to decrypt the files afterwards.
Code:
...ANSWER
Answered 2021-Jan-03 at 15:18The way you're encrypting data makes no sense. Asymmetric encryption can only encrypt a small, fixed amount of data. Never use asymmetric encryption such as RSA-OAEP for anything other than a symmetric key, and use that symmetric key to encrypt the actual data. For the symmetric encryption, use a proper AEAD mode such as AES-GCM or ChaCha20-Poly1305. This is called hybrid encryption.
Other things that are wrong with your code:
- A 1024-bit RSA key is not enough for security: 2048-bit is a minimum, and you should prepare to move away from RSA because its key sizes don't scale well. (Feel free to use 1024-bit keys for testing and learning, just don't use anything less than 2048-bit for RSA in production.)
- The encryption is a binary format, but you join up lines as if they were text. Text or binary: pick one. Preferably use a well-known format such as ASN.1 (complex but well-supported) for binary data or JSON for text. If you need to encode binary data in a text format, use Base64.
If this is for real-world use, scrap this and use NaCl or libsodium. In Python, use a Python wrapper such as libnacl, PyNaCl, pysodium or csodium. Use a public-key box. The Python APIs are slightly different for each Python wrapper, but all include a way to export the keys.
If this is a learning exercise, read up on hybrid encryption. Look inside libsodium to see how to do it correctly. Key import and export is done with the methods import_key
and export_key
. Symmetric encryption starts with Crypto.Cipher.AES.new(key, Crypto.Cipher.AES.MODE_GCM)
or Crypto.Cipher.ChaCha20_Poly1305.new(key)
(Crypto.Cipher.AES.new(key, Crypto.Cipher.AES.MODE_GCM, nonce=nonce)
or Crypto.Cipher.ChaCha20_Poly1305.new(key, nonce=nonce)
for decryption).
QUESTION
When i try to start the bot i get the error: TypeError: generator() missing 1 required positional argument: 'ctx'
...ANSWER
Answered 2021-Jun-15 at 04:44The error says it all. You can't use ctx in events since ctx represents the Context where command is provoked. Read the docs about ctx here: https://discordpy.readthedocs.io/en/stable/ext/commands/api.html
In order to send a message to a specific channel use bot.get_channel(id)
which will return a discord.Channel
object and then you can use discord.Channel.send()
to send a message to that channel.

I'm trying to make a small simulation of traveling salesman in Unity C# and I can't get through this, my code looks right but start and nxtCity vectors always result in the same position, I really can't understand why, could any of you help?
cities is the number of total cities
positions is the array of cities taken from cities generator these two values are right in unity editor
Here the code:
...ANSWER
Answered 2021-Jun-11 at 00:22Unity's Random.Range with (int, int) overload (NOT float, float) generates random number in range [min; max), max is exclusive, so if you call var randomInt = Random.Range(0, 1)
result will be always 0. var randomInt = Random.Range(0, 2)
would be 0 or 1, e.t.c
