How a rocket launch fail? Re-use of code written for 32-bit system on a 64-bit data range.
Novo is the powerfully simple small business banking platform that’s resetting expectations of small business banking. Complete with integrations to tools small business owners are already using like Stripe, Shopify, Square, and Quickbooks Online.
a paper on an open-source fully automatic large-scale SSO landscape, security, and privacy analysis tool. They automatically identified 1,632 websites with 3,020 Apple, Facebook, or Google logins within the Tranco 10k and analyse them. Some fact such as 10% of SSO is failed because of mis-configuring redirect_uris. The paper is also a remind for us to cleanup stuff and make sure our SSO, especially for internal tooling/documents is up to date with the right config.
A new take on the age-old question: Should you rewrite your application from scratch, or is that “the single worst strategic mistake that any software company can make”? Turns out there are more than two options for dealing with a mature codebase.
DNS in kubernetes is more complex than in a normal server. Because there are service dns, and they have namespace and cluster domain as suffix, but namespace and cluster domain can be omitted. Therefore it creates more work to check wherether a name belongs to k8s resources.
PostgreSQL is impressive with its featureset. But there are always gotcha and annoying. I also learn some useful pg extension such as pg_safeupdate to block update/delete without a where filter.
Many people know horror stories about anti-wraparound autovacuum tanking performance or databases that stop working, but who has ever seen actual data loss? The most high profile public incident with this that I know was belong to Sentry
In this short series, we’re going to add a user defined function to SQLite in C. We’ll go through the process slowly and in a way which, I hope, a C novice can follow
fly.io allow you to deploy your app as in a Heroku experience. They use Nomand behinds the scene, and out grow it so the build flyd. It’s quite different from K8S or Nomand. flyd operates like a market. Requests to schedule jobs are bids for resources; workers are suppliers.
