Good news! Just got a reply from them and they have increased the connection limit. They did not specify what the new number is, but hopefully it is high enough to not be an issue for the foreseeable future.

So, if you do run into other similar reports after this comment I would appreciate it if you tag me again.

Thanks!

Cost is not the bottleneck in this case... The problem is that I am rather ignorant about the options and their benefits/limitations. Moving the images the first time was painfully slow because of those same rate limits, and I expect the next migration to be the same, so I want to make a better choice next time and would rather find a solution with the current provider ๐Ÿ˜…

Thanks for the heads up. I am still trying to resolve this without a migration... I will try again to get a response from them as they have not replied in a week.

This is the current status:

  • The instance is serving the images via object storage. Specifically, I am making use of Contabo to save and serve the images.

  • I now know that the default limits are 250 requests / second and 80 Mbit/s: https://help.contabo.com/en/support/solutions/articles/103000275478-what-limits-are-there-on-object-storage-

  • It appears to me like when the requests are exceeded, the "Too many requests" error is triggered and it takes a few seconds before the requests are accepted again. This can happen if few users access the front page at once as this will fetch all of the thumbnails and icons on the page.

  • I have been in touch with Contabo's customer support via e-mail. But they mis-understood my original e-mails and thought I was speaking about increasing the maximum number of images that can be stored (3 million by default). I have clarified that I want to increase the rate limit and have been waiting for their response for a few days now.

  • The other solution would be to move the images to a different object storage provider. The migration is also limited to the 250 requests/s and 80 Mbit/s, so it will require turning off the images for 4 - 7 days while all the images are moved... Since I am not familiar with the policies of other object storage providers I would also need to do research to avoid falling into the same trap.

So, I am hoping that Contabo's support will get back to me soon and allow me to increase the rate limits, as this would be the most straight forward approach.

And you are doing a great job at that! ๐Ÿ˜„

Very interesting article, thanks for sharing. I agree that it is a good one to pin!!

I have been reaching out to the object storage provider to see if I can increase the rate limits... Unfortunately I might need to change to a different provider to overcome this. Since the migration takes several days, especially so because of those same rate limits, I would rather avoid this...

That's an error I had not seen before, but I also just encountered with this specific post. I will investigate, thanks.

[โ€“] [email protected] 7 points 1 month ago (2 children)

This error is a rate limit from the object storage provider. I did not know of this limit when I chose them, and I still have not found a way to change the limit. I will send them an e-mail. If the limit can't be increased, one option is to pick another object storage provider, but the migration takes days.

Check in your settings whether you have disabled the visibility of bot responses. This can happen if bots replied to you and your settings are set to not see them.

[โ€“] [email protected] 13 points 2 months ago (1 children)

Thank you for being alert! I have banned them instance-wide now.

I think that they are referring to Paxillus involotus

It is quite an interesting mushroom. It was considered "safe to eat" for a long time, but it contains an antigen that a human's immune system can learn to attack.

The antigen is still of unknown structure but it stimulates the formation of IgG antibodies in the blood serum.

I once looked into whether this immune response builds up over many exposures, or if it is a random event that has a probability of happening for each exposure. I don't remember finding a convincing answer... If it is a random event, then mushroom could be considered a "Russian roulette" mushroom that will usually provide a nice meal, but, if unlucky, you may experience the following:

Poisoning symptoms are rapid in onset, consisting initially of vomiting, diarrhea, abdominal pain, and associated decreased blood volume. Shortly after these initial symptoms appear, hemolysis develops, resulting in reduced urine output, hemoglobin in the urine or outright absence of urine formation, and anemia. Hemolysis may lead to numerous complications including acute kidney injury, shock, acute respiratory failure, and disseminated intravascular coagulation. These complications can cause significant morbidity with fatalities having been reported.

I agree with you that this is probably unrelated to the "generally similar to humans" comment. I feel like this fantasy is a combination of the above fact mixed in with the fact that the Fungi belong to the Opisthokonts, which places them closer to animals than plants, and so they share some interesting cellular characteristics with us. This places them closer to animals than plants, but "generally similar to humans" is perhaps a bit of a stretch ^_^

But, it is just a meme about a guy being hyped about mushrooms. Hopefully people don't expect memes to be super accurate ๐Ÿ˜

I purchased a PCIe DAQ card from National Instruments (PCIe-6536B), and I have struggled trying to get their proprietary drivers installed so that I can interface with the card using the NI-DAQmx library in Python.

I am considering giving up on it. Has any of you worked (or tried to work) with these cards in Arch? If you can share how you managed I would appreciate it.

But, really, even knowing that someone has succeeded would be enough to motivate me to continue trying. And knowing that others have also struggled and failed would help me confirm that National Instruments is not the way to go.
