Some quasi-journals have been moving in a "magazine-style" direction with broader-interest articles than a traditional journal, in order to fill some of the trade-magazine gap. Some more successfully than others.
A few that I sometimes read:
ACM Queue: http://queue.acm.org/. Online-only, free. Focus is largely on software engineering and some related areas (sysadmin, devops, architecture, reliability engineering, etc.). Probably the closest to a Dr. Dobbs style magazine of the ones I list here, with mostly industry authors.
Communications of the ACM: http://cacm.acm.org/. Most recent issue is free online; print subscription w/ digital back-issue access is $99/yr. Mix of academic and industry articles, leaning more academic, but written in a more accessible and concise style than a typical CS journal. The print version also includes some articles from online-only ACM publications (like Queue).
AI Magazine: http://www.aaai.org/Magazine/magazine.php. Issues >1 yr old are open-access online; new issues are subscription-only. Print+digital subscription is $145/yr. A bit like CACM, in being journal-ish but with an aim at more readable general-interest articles. Some insider-ish news/column type stuff as well (reports on conferences and workshops, etc.).
You may or may not be happy with any of those. The move towards a more magazine-style format is pretty new, and I think still being experimented with. I personally like glancing through and reading parts of CACM and AI Magazine, and less often Queue. I also know some people who like the general-audience IEEE magazines (IEEE Computer, IEEE Software, IEEE Micro, etc.), but I haven't read them enough to have an opinion.
