That was the best cup of coffee ever: it tasted like victory. A while ago I attempted to repair an friend's espresso machine. We disassembled it, cleaned it, and managed to run self-test mode: nothing was wrong with the hardware, every single pump, heater element, motor drive, was working fine. We checked every single voltage on the board, nothing suspicious. And yet, it was not brewing coffee. Then I found one of those passionate people forum, one about espresso machines, and they were describing my issue exactly: apparently my firmware got stuck or corrupted. They also provided binaries to reflash my microcontroller. So I took the board home, borrowed a PIC programmer, and reflashed this firmware I downloaded from a forum on the Internet. Needless to say, I was not placing lots of hopes in my repair at that point. And yet, when I got back at my friend's with the board, the miracle happened: the machine started up, flushed its pipes, heated some water, and eventually made a coffee. To be frank, I don't get a lot of wins when I repair stuff, this is one droplet of victory in an ocean of headaches and blunders and failures. But this one cup of victory coffee made it all worth it . If you want to know more or see what a victory coffee looks like, all the details are in the #ifixit tutorial: https://lnkd.in/eEMjY9Db

𝙍𝙚𝙨𝙤𝙡𝙫𝙞𝙣𝙜 𝙄𝙢𝙥𝙤𝙧𝙩 𝘾𝙮𝙘𝙡𝙚𝙨 𝙞𝙣 𝙂𝙤: 𝙒𝙝𝙮 𝙣𝙚𝙚𝙙 𝙤𝙛 𝙘𝙤𝙢𝙢𝙤𝙣 𝙥𝙠𝙜 𝙞𝙣 𝙜𝙤 !! In Go projects, import cycles can occur when two or more packages import each other directly or indirectly, leading to the "𝙞𝙢𝙥𝙤𝙧𝙩 𝙘𝙮𝙘𝙡𝙚 𝙣𝙤𝙩 𝙖𝙡𝙡𝙤𝙬𝙚𝙙" error. Here's a case study from our project to illustrate how we resolved such an issue. 𝙋𝙧𝙤𝙟𝙚𝙘𝙩 𝙎𝙩𝙧𝙪𝙘𝙩𝙪𝙧𝙚 Our project is organized under the 𝙥𝙠𝙜 directory, with a 𝙛𝙤𝙤 package that contains several sub-packages like 𝙗𝙖𝙧, 𝙯𝙖𝙧, etc. 𝙏𝙝𝙚 𝙋𝙧𝙤𝙗𝙡𝙚𝙢 The 𝙛𝙤𝙤 package was importing the 𝙗𝙖𝙧 package to use the 𝘽𝙖𝙧𝙍𝙚𝙨𝙪𝙡𝙩 type. Meanwhile, the 𝙗𝙖𝙧 package started importing constants like 𝘒𝘜𝘉𝘌𝘊𝘛𝘓_𝘝𝘌𝘙𝘚𝘐𝘖𝘕, 𝘗𝘖𝘋_𝘕𝘈𝘔𝘌, and many others from the 𝙛𝙤𝙤 package. This mutual dependency led to an import cycle. 𝙏𝙝𝙚 𝙎𝙤𝙡𝙪𝙩𝙞𝙤𝙣 To resolve this import cycle, we moved the shared constants and variables to a new 𝙘𝙤𝙢𝙢𝙤𝙣 package under the 𝙛𝙤𝙤 package. This decoupled the dependencies and eliminated the import cycle. 𝘾𝙤𝙣𝙘𝙡𝙪𝙨𝙞𝙤𝙣 By moving shared code to a separate 𝙘𝙤𝙢𝙢𝙤𝙣 package, we successfully resolved the import cycle issue. This approach not only eliminated the circular dependency but also made our codebase more modular and maintainable.
