对于关注The Jacker的读者来说，掌握以下几个核心要点将有助于更全面地理解当前局势。
首先，The original KEF Muo launched back in 2015 and felt like a turning point in portable hi-fi. Serious, designer Bluetooth speakers from a respected hi-fi brand were rare back then—with only a few brands like Bang & Olufsen and Loewe interested in combining pretty and portable. These early designs were still given the side-eye by most traditional audio. At the time I was impressed by the sound of the original Muo and horrified by the price.

第三，What has evolved is the cottage industry of musical accessories that utilize MIDI to do wild and wonderful things. Are you keen on adjusting filters and delay times with the swipe of your hand like a deranged conductor? There’s a MIDI gadget for that. Do you idolize U2’s The Edge and his ability to change his guitar tone drastically with just one foot press? There’s a MIDI pedal for that. Would you rather not schlep around a fortress of synths a la Keith Emerson just so you can access an organ and an electric keyboard for that wedding gig on the horizon? There’s a MIDI controller (and a synth module or two) for that.
此外，The biggest change is to how Google will collect fees from developers publishing apps on Android. Rather than take its standard 30 percent cut of in-app purchases through the Play Store, Google is lowering its cut to 20 percent, and in some cases 15 percent for new installs of apps from developers participating in its new App Experience program or updated Google Play Games Level Up program. Those changes extend to subscriptions, too, where the company’s cut is lowering to 10 percent. For Google’s billing system, the company says developers in the UK, US, or European Economic Area (EEA) will now be charged a five percent fee and "a market-specific rate" in other regions. Of course, for anyone trying to avoid those fees, using alternatives to Google's billing system is getting easier.，推荐阅读新收录的资料获取更多信息
