Hello all!
I have some news to share about CF-Predictor (a service that allows you to view rating changes before official results). This extension was launched almost 6 years ago. Number of users has grwon from a couple hundreds to nearly 50k! I'm very proud that this service is used by so many people!
One of the cool features of mine extension is that it is friendly to codeforces API :) All the request to codeforces are sent from just one backend server. Therefore, users don't overload codeforces with extra API calls.
I was using Heroku as a cloud provider to run my servers. Unfortunately, they are closing their free accounts on Nov 28th. So, I decided to take down my servers on heroku. Thus, starting from 2022-11-27 cf-predictor-frontend.herokuapp.com and cf-predictor.herokuapp.com will not work.
On a bright side, I though that upsetting 50k people isn't a good thing. Therefore, I'm renting a VPS and you can continue to use CF-Predictor via cf-predictor.wasylf.xyz! I already updated extentions for Chrome, Mozilla and Opera to use the new backends. However only Mozilla has accepted the new version so far. I hope the changes will be reviewed quickly and you all will be able to use new version soon!
Good luck to all of you and have a high rating!
how much money did you spend on this operation
VPS cost 6$ per month. VPS has 4 GiB RAM and 2 cores. If you know know better deals, I'm happy to check them out :)
For now I treat it as an "educational protect". It was interesting to learn how to setup reverse pricy, SSL. Next, I'm planning to setup some monitoring, look into continues integration. All of these are very simple with cloud, I'd like to go one layer deeper:)
where did you find a vps with those specs that cheap?
I found this provider. I'm using it for less than a week, so don't have much inside:) but so far everything looks good!

thank you

Thanks for keeping it alive all this time 🧡
Just in case you want to cut the bill, I've been using the following free compute engine resources https://cloud.google.com/free/ https://aws.amazon.com/free/
Thanks for advice. I was using AWS in 2017, so I run out of 12 months free computing.
Free compute engine in Google cloud seems to be limited to just 1GB network egress, it's not enough :(
(firefox) Found it as good as before. Thanks a lot.
Thanks for the confirmation :)
Yes, Firefox and Chrome stores have accepted the new version (
1.3.2). The review is still pending for Opera.Hey there, thank you for this app since it helped me a lot on grinding for the new level. I believe that you might want to check out this platform to host your website for free.
Thank you! Will check it out!
From the first glance, it looks like the platform doesn't support Java and my servers are written in Java.
It is not working anymore
