RegExr VS self-hosted

When thinking about how I might compare an arrangement to the contiguous group of damaged springs, I used regexr.com to experiment with very specific regexs that used the numbers.

There are plenty of online regex tools to test and experiment with regex patterns. Some popular ones include RegExr, RegEx101, and RegexPlanet.

Using regexr.com it at least appears to work as expected.

If you are going to use RE's, use something like https://regexr.com/ to double check that they're doing what you want. I was suspicious of your 'cols = re.findall(r'\d+ .....', i)' line, and indeed it does miss some columns. You should rethink your column detection, and either not use REs or learn how to use capture groups and \w. There would then be no reason to use yet another RE in your column iterator to extract the numbers which you've already detected.

First time posting here, let me know if I need to edit post to conform to any rules. My issue is that I'm trying to match regex pattern to separate out the number of cubes drawn and its color but my Matcher object seems to not be returning any matches so it's throwing a no match found exception when I try to call digitMatcher.group(). I have tested my regex pattern on sites like regexr and it seems to pass there but it's not working for some reason here. I use the same type of regex on day one and it work there so I'm not sure where my regex pattern is failing here. I'm talking about specifically in my isGameValid() method where I create a matcher base on a pattern I made above. Through debugging I know that I separated the string color pairing correctly and that my Matcher object has the correct regex pattern, it's just not matching for some reason. Any help would be appreciated. Code below:

Regexr has been an invaluable tool as a beginner.

RegExr simplifies working with regular expressions. This online tool provides a visual interface for building and testing regex patterns in real-time, making regex less intimidating.

Ho did you arrive at the regex? I usually use a website to , such as https://regex101.com/, https://regexr.com/, https://regex-generator.olafneumann.org/ in combination of each other, as some explain better than the other.

I pulled this into regexr.com and it yielded the same results except it removed :41:

This is the point where I will point out that you can self-host Sentry free of charge :) https://develop.sentry.dev/self-hosted/

Sentry can be self hosted: https://develop.sentry.dev/self-hosted/

The people we're concerned about are not the hundreds of thousands of Sentry users, including those that self-host.

We're concerned about people who have taken the software for the purposes of competing directly against us, that hinders our ability to monetize the work. Monetizing the work helps us continue improving the software and distribute it for free use, benefitting those aforementioned real users (e.g. https://github.com/getsentry/self-hosted).

> I mean no slander or disrespect to anyone involved, but there was a DataDog alternative posted sometime in the last few weeks that had a docker-compose with like 15 containers in it.

Reminds me of Sentry: https://develop.sentry.dev/self-hosted/

This is their example docker-compose for self-hosting: https://github.com/getsentry/self-hosted/blob/master/docker-...

It has:

> What should people use?

I recall Apache Skywalking being pretty good, especially for smaller/medium scale projects: https://skywalking.apache.org/

The architecture is simple, the performance is adequate, it doesn't make you spend days configuring it and it even supports various different data stores: https://skywalking.apache.org/docs/main/v9.0.0/en/setup/back...

The problems with it are that it isn't super popular (although has agents for most popular stacks), the docs could be slightly better and I recall them also working on a new UI so there is a little bit of churn: https://skywalking.apache.org/downloads/

Still better versus some of the other options when you need something that just works instead of spending a lot of time configuring something (even when that something might be superior in regards to the features): https://github.com/getsentry/self-hosted/blob/master/docker-...

Sentry is just the first thing that comes to mind (OpenTelemetry also isn't simpler due to how much it tries to do), but compare its complexity to Skywalking: https://github.com/apache/skywalking/blob/master/docker/dock...

I wish there was more self-hosted software like that out there, enough to address certain concerns in a simple way on day 1 and leave branching out to more complex options like OpenTelemetry once you have a separate team for that and the cash is rolling in.

Sounds interesting!

Will you compare with qryn? Self-hosted sentry?

qryn.metrico.in/

https://develop.sentry.dev/self-hosted/

I haven't done it in years, but technically sentry is able to be self hosted https://github.com/getsentry/self-hosted

yes to the second https://github.com/getsentry/self-hosted/blob/23.4.0/docker-... and only after the embargo is over to the first: https://github.com/getsentry/self-hosted/blob/23.4.0/LICENSE...

I also miss the "good old days" when running sentry was like 3 containers, not the 32 of modern Sentry
