Hi everyone, welcome to first issue of November. This week, where I live, red leaves start to emerge and my family went outside, enjoy seeing the beautiful color of autumn. Social media had been a tough week with Twitter and Elon, same as finance system and crypto drama. The world looked so depressing, but no matter what, being a programmer, knowing how to code is really a privilege, we have a way to make a living while sitting at a deck doing thing we enjoy. No matter what happen, there will always a demand to make website, application or service and a continous stream of jobs require to run these things. We are thankful for the jobs and opportunities we had, be optimist and always leaning. on ward. have a good week everyone.
