Como dividir uma imagem em 4 tons diferentes? Python

Bom Dia. Estou tentando fazer uma divisão de imagem em tons: vermelho, verde, azul e cinza (tons de cinza). Até agora só consegui fazer toda a imagem mudar para um único tom, mas meu objetivo é dividi-la em 4 quadrantes e cada um com um tom diferente. Anexei o código onde posso mostrar a imagem com um único tom:

from PIL import Image

    img = Image.open("imagen.jpg")
    layer = Image.new('RGB', img.size, "blue")
    salida = Image.blend(img, layer, 0.5)
    salida.show()

Alguém poderia me aconselhar? Não sei dividir a imagem com os tons que necessito, já tentei modificar o código acima mas não tive sucesso.

How to Make Tons of Sales Daily with Instagram, with No Ads Cost

Recently, a buddy introduced me to ProfileMate, the new instagram marketing app on the block.

It allows one to quickly access thousands of profiles daily on IG, and one can easily generate qualified leads daily for free.

With this app, one can ethically generate tons of emails and phone numbers among other essential data daily, and then market to these to boost sales.

On my first week using ProfileMate, I was able to experience 4% conversion from 5000 prospects, which gave me around 200 unit sales for my ecom store offer.

It’s currently on its launch price around $62 one time fee, with room to go to hundreds of dollars soon. I actually got it at $47 as one of its early launch takers.

Why does our MySQL server become non-responsive with the processlist showing tons of processes waiting in STATE=init, INFO=commit?

I work for a company that’s been around for a while and has a large MySQL (5.6.48) monolith running in RDS. Recently, the database has starting going unresponsive for 10-30 minutes at a time during peak traffic time. This often happens 3 or 4 times throughout the peak traffic hours.

During these unresponsive times, it is almost impossible to open a connection with the database (timeouts are the most common response). If you get a connection, queries normally perform as expected for a short while. The processlist shows dozens to hundreds of items with state “init” and info “commit”. Row operations drop nearly to zero and stay there for minutes on end until the database suddenly begins to recover, the processlist clears, and it becomes responsive to traffic once again.

What we have attempted so far:

  • We have tried to remove all slow queries during these peak hours, shutting down large swaths of functionality and workers during these times.
  • We have increased the redo log size in innodb.
  • We have looked for lock contention and deadlocks.
  • We have doubled the compute power, memory, and throughput available to the RDS instance. (DB CPU usage during peak hours hovers around 50% and there are no alarming spikes in memory or disk or network usage.)
  • We have tried using proxy servers to hold open long-lived connections to the database.
  • We’ve looked for any recent changes or new queries introduced in the app.

All of that only helped a little bit. We often still see at least one “storm” where we get stuck in the bad state, and re-enabling any batch jobs tends to push us over the edge.

Has anyone seen the pattern of processes getting stuck in STATE=init, INFO=commit for minutes on end? Does anyone have suggestions on how to proceed with debugging or analysis? What other resource contention could we be running into?

[FREE] BaDoinkVR Ripper V1 – Get access to tons of hi-res adult images and trailers | Proxies-free

Well, seems that this forum is popular on porn related topics and i have decided to contribute to it…
This script is free…

My script is called BaDoinkVR Ripper V1 and basically it connects to BaDoinkVR servers using a bug and gets links for hi-res adult images and trailers. The user can then remote upload this files to file hosting sites and monetize.

BaDoinkVR Ripper V1 only works with Internet Explorer and you must allow scripts to run. The script only gets the trailers and images in a archive format, if browsed manually the user can get access directly to the movie file and remote upload directly to video hosting sites. This is useful for porn uploaders as they don’t need to waste any bandwith and get good content.

Tons of calls to ad pages

First, I don't really know where to post it and I don't really know what to do, so I hope this is a good place to start. I used and filtered Wireshark to find client hello packets. Many of the server names that make up these packages include domains such as cdn.adsafeprotected.com, sb.scorecardresearch.com, and rtbgumgum.com. I wondered how I could prevent it.
