As the web has evolved, more sites are served over HTTPS. The discuz-ucenter-api-for-java library that connects Discuz's UCenter to Java runs into trouble over HTTPS: it's a very old project that hasn't been updated in ages and doesn't support HTTPS endpoints. So I updated it.
Newer DBeaver versions no longer support ODBC connections, probably because the JDBC-ODBC bridge was removed from Java 8. So the old tutorials telling you to use ODBC no longer work. Here's the correct way to connect DBeaver to DaMeng.
In SQL, the LIKE operator searches for a specified pattern in a column inside a WHERE clause. It's a very common way to query in practice, and most people only use the % wildcard — but several other patterns are supported too.
An IPA signed with an iOS enterprise certificate can't be listed on the App Store. It can only be distributed out-of-band — for instance, by putting a QR code on your company website that Apple users scan to install. Between the IPA file and the QR code you need a plist file describing your app, and installation goes through the itms-services protocol. That's what this tutorial covers.
I connected my Spring Boot main site with a Discuz! forum so login and logout are synchronized, and member data from Discuz! can be shown back on my site. I also modified the previously open-sourced discuz-ucenter-api-for-java to fit the way Spring Boot is written today.
After upgrading to a newer Druid, the logs kept throwing errors: discard long time none received connection., jdbcUrl: blah blah. The program ran fine, but staring at a wall of errors is unbearable, so I went into their source to see what was actually going on.
Today I suddenly noticed a new badge on my GitHub profile, 'Arctic Code Vault Contributor' — which translates to 'Arctic Code Vault Contributor' — so I looked into this Arctic Code Vault.
GitHub Actions is a continuous integration service launched by GitHub in October 2018. I used Travis CI before; yesterday I tried GitHub Actions and found it more powerful with more to play with, so I'll share my first impressions.
Why do I say don't over-rely on or blindly trust unit tests? It starts with a merge request. GitHub's Dependabot keeps your application secure and always up to date, meaning it automatically creates merge requests to change my Maven dependency versions. And so the story begins.
Download sites were very popular several years ago, but because bandwidth and traffic were expensive, many download sites began hotlinking — visitors click download on someone else's page but use my server's traffic, causing huge bandwidth theft. So hotlink protection is a required course for download sites.
