Seconding IEEE Spectrum, it covers a broad number of fun technical topics. Off the top of my head, some articles over the past year included supersonic transportation, satellite transmissions, crowdfunded space travel, COVID detection mechanisms, software failures, and data compression. Communications of the ACM is also a good print magazine if you are interested in computer science. It has more of an academic bent, but is meant to be of general interest to computer scientists (disclosure: I'm on the Editorial Board of CACM). Again, off the top of my head, some recent articles include K-12 computer science education, a survey of word embedding techniques, software-defined cooking using a programmable microwave (I'm a co-author of this), differential privacy, a survey of AI bias issues, and Green AI.
