Brazilian living in NL, experienced in both. I think biggest difference is Tikkie doesn't give you an easy identifier. Great for privacy, but being able to send money to your email/phone number makes a difference for some real time use cases. QR code helps, but it is not the same.

Honeycomb. Amazing observability tool and reasonably cheaper/better than alternatives.

The PEV2 is open source and give you a good visualization. I never used this pgmustard to compare.

Migrating primary keys from int to bigint is feasible. Requires some preparation and custom code, but zero downtime.

I'm managing a big migration following mostly this recipe, with a few tweaks: http://zemanta.github.io/2021/08/25/column-migration-from-in...

FKs, indexes and constraints in general make the process more difficult, but possible. The data migration took some hours in my case, but no need to be fast.

AFAIK GitLab has tooling to run tasks after upgrade to make it work anywhere in a version upgrade.

It says more about brazilian municipalities than about chatgpt. Probably nobody read this one and many other voted documents.

I think most companies wouldn't even consider it a security bug.

New Relic. Unfortunately it reduced their free plan (and the paid plan is expensive), but I was always amazed about their free features. I'm still didn't find a good alternative. :(

To be honest, I have no idea. Maybe I'm even wrong about why it works.

I have a toy service with ~200k requests/day to a public service and I was blocked all the time.

After I changed to use API Gateway + Lambda as a proxy, never had these problems again. I just monitor the 4xx and 5xx errors and they are almost zero now.

I'm using it as a proxy with IP rotation. It is not a perfect solution, but solved my problem more than one time.

It is a lot cheaper than a "proxy as a service".

It is not "with no cliff". It is a "4 year cliff". Possibly they are inexperienced and don't know what they are doing.

In some countries, your solution is more expensive than the BTC CC fee.

I think the best way to do it is mixing internal development and clients. You can leverage their money to build whatever you want.

Exactly. Just get data from other places and make it simple, beautiful, useful. Government has a lot of interesting databases with disgusting presentation.

All my websites are focused on brazilian market (pt-br).

Sure! My websites aren't global, I'm sure people can replicate some of them in other countries.

Send me emails to my username at gmail.

They make USD 1.5-2k. In my country, it is a mid-level developer salary, enough to cover expenses.

Most part come from Criteo and Adsense. Adsense has better performance, but is not reliable, some sites were banned without reason. I always test other ad networks, but these have the best performance to me.

The biggest site has generated content. It is more like a places database, based on third-party APIs.

The other sites I wrote the content. It is not a good content, but most part is original.

I'm not willing to share my sites, but I have some content websites, one of them have ~2 million pageviews/month and is enough to pay my bills. The others are small, but they improve ~10% my result.

They are 99% passive income. All of them can be improved, but I don't do anything, I have full time job and other side projects. I feel bad for not working on them, but I know it is the right decision to me.

To be honest, it was started as a SEO experiment. I have bad content in good shape (all in-page SEO tricks done). I'm sure better content can improve my results.
