During our last adventure into the realm of format string exploitation, we learned how we can manipulate format specifiers to rewrite a program's memory with an arbitrary value. While that's all well and good, arbitrary values are boring. We want to gain full control over the values we write, and today we are going to learn how to do just that.

I don't know how many of you had this experience in your youth, but when I was a kid, I used to actively think about what would happen if I suddenly woke up in a fantasy land, or were to pass through a portal into another space and time. I knew it wouldn't really happen, but when you're a kid, these can be important issues to you. So I slept with my glasses on every night, just in case. Photo from George Pal's The Time Machine.

The landscape of the augmented reality space is broad, diverse, and constantly shifting, perhaps more so than any other vertical in technology.

My autistic son loves music. One afternoon, when he was nine, I downloaded GarageBand to his iPhone to help with the boredom of a long wait at a doctor's office. Instead of pacing or escalating into a meltdown, he spent the entire hour and a half practicing, learning, and composing. When we finally left that day, the rest of us exhausted and irritated, he shared his first composition with a big smile.
The wait wasn't so long this time. Apple released public beta 3 for iOS 13 on Thursday, July 18, just one day after the release of developer beta 4. For context, Apple took five days to seed public beta 2 after releasing dev beta 3, so it's a pleasant surprise that the latest public beta dropped so soon.
We're pumped for iOS 13 and all of the fresh features and changes that come with it. Developer beta 3 came with new features in the double digits, including AR eye contact in FaceTime and mouse cursor size customization. Developer beta 4, released today, has a few more additions and changes as well.

Around the end of each year, Spotify offers a year-in-review service so its users can see what they listened to the past year and share their listening histories in fun infographics. Apple Music does not have such a feature, unfortunately, but there is a way to curb that FOMO feeling this holiday season by downloading your listening history not just for 2018, but for the entire lifespan of your account.
Media subscriptions are all the rage these days. Between Netflix, Apple Music, HBO Now, and countless more, your TV, movie, and music options have never been better. Unfortunately, all these choices weigh heavily on your wallet. So, when there's an opportunity to snag not just Spotify but Hulu and Showtime as well, all for just a tad bit over five dollars a month, how could you turn that down?

The road to becoming a skilled white hat is paved with many milestones, one of those being learning how to perform a simple Nmap scan. A little further down that road lies more advanced scanning, along with utilizing a powerful feature of Nmap called the Nmap Scripting Engine. Even further down the road is learning how to modify and write scripts for NSE, which is what we'll be doing today.
Nmap is more powerful than you know. With a few scripts, we can extend its functionality beyond a simple port scanner and start to identify details about target servers sysadmins don't want us to know.

Android lets you sync your contacts across devices. The OS will use not only contacts saved on your phone, but also your Gmail. This choice can lead to a contacts list populated with entries that don't have a phone number, which can quickly add up. To mitigate this problem, there are a few methods.
Introduced on the iPhone 6s, 3D Touch is just about the closest thing to a "right-click" that we have on iOS. Apple and app developers utilize this feature to give us helpful options that might otherwise clutter the overall app experience, as well as opportunities to "peek" into an action without committing to it. Safari on iPhone is no exception.
Apple has tools built into iOS to help parents monitor the iPhone habits of their children. However, those same tools can be used by everyday iPhone owners to both hide apps they don't care about, as well as restrict features they don't need or that infringe on privacy.
