Every time, it felt like the right thing to do. The code looked more “professional.” More engineered. But the users didn’t get their feature any faster, and the next engineer to touch it had to spend half a day understanding the abstraction before they could make any changes.
近期中东地缘局势持续紧张，霍尔木兹海峡航运安全引发全球关注，原油价格应声上涨。在此背景下，A股油气板块大涨，多家上市公司涉中东地区业务亦受到市场关注。3月2日，以投资者身份致电洲际油气和中曼石油，前者表示，目前公司涉伊拉克地区业务正常开展，预计2027年释放产能；后者表示，公司伊拉克项目所处地理位置相对安全，当前中东局势最主要影响的是油的输出，公司伊拉克油田还未完全采油出油，故影响有限，“我们预计产量出来的话还要等到2028年，真正达产做成产品往外销的话肯定还要更久一点”。
