Friday Q&A 2017-06-30: Dissecting objc_msgSend on ARM64 Friday Q&A 2017-06-30: Dissecting objc_msgSend on ARM64 We're back! During the week of WWDC, I spoke at CocoaConf Next Door, and one of my talks involved a dissection of objc_msgSend's ARM64 implementation. I thought that turning it into an article would make for a nice return to blogging for Friday Q&A. Overview Every Objective-C object has a class, and every Objective-C....

550 words, 2 minutes. Final Remarks “All men can see the tactics whereby I conquer, but what none can see is the strategy out of which victory is evolved” - Sun Tzu. This is the 6th and final post in a short series on winning systems for security practitioners. The first postfeels like a while ago already, about 6000 words or 25 minutes. Those minutes haven’t been wasted. The Inevitable Car Analogy If you’ve come this far then you’ve alread..

1450 words, 5 1/2 minutes. Resilience “In defeat: Defiance” - Winston S. Churchill. This is part 5 of 6 in a short series of posts on winning systems for Information Security practitioners. It aims to plug the gap between policy and products and put you, the practitioner, back in the driving seat. After all if you don’t know what system you’re implementing, how can you decide what products or features are important to you?

1100 words, 4 1/2 minutes. Preparation “One of the best ways to keep peace is to be prepared for war” - Plato & others. Today attacks come thick and fast. The chances are that all public IPv4 address space is regularly scanned. Time-to-compromise of an unpatched, non-firewalled, Microsoft Windows host is about 5 minutes. Systems are attacked not because they are valuable, but because they are vulnerable. Even an old cable-modem is a useful ..

1100 words, 4 1/2 minutes. Introduction “Never tell people how to do things. Tell them what to do and they will surprise you with their ingenuity." - George S. Patton If you’ve read my previous postyou’ll know that to get beneficial, long lasting, low-maintenance results in Information Security, you need winning systems. Not skills. If you like grinding monotony punctuated by periods of extreme stress and being able to tell people how busy ..

1100 words, 4 minutes. This post is one of a short series on structural and systemic things the Information Security industry does wrong, and what we might do about them. Disclaimer: I advocate lifelong learning, that includes professional training, product training, workshops, online or in-person courses, and academic study. The professional trainers I know who author and deliver their own material are among the most mentally agile people ..

Running Cucumber scenarios in parallel can be tricky, especially when a custom test runner is used. That's why we created Cucable - a Maven plugin to split test scenarios into smaller chunks that can be run at the same time.

Ideally, the chosen platform permeates throughout the ranks of the organization instead of having fractured communication between members. The real-time and group collaborative nature of these messaging pla....

A method for signing in to a device that doesn’t have a keyboard When we were developing our SoundCloud app for Xbox One, something became very obvious during usability testing: signing in with a game controller really sucks. Entering text requires navigating a virtual keyboard to individual letters, numbers, and characters one at a time – such a nightmare! Plus, letters, numbers, and special characters are spread across three screens. The ..

A very brief update about the progress of searchcode server. Currently I am in the middle of reworking how the index is built and maintained. The idea being I want to add zero downtime index rebuilds which requires a blue/green index strategy. It is still very much in flux but the current design is to merge the indexer and searcher which should allow this to happen. I have been playing around with using an iPad as a production device these ..

By trying to winning the things that don’t matter. You’re playing a poker game, but you’re not really good, and you can really get tricked by the sharks. They’ll give you a few bites, and whet your appetite. You come rushing and eager into their trap and lose the skin off your back. You’re in a relationship, and inevitably end up arguing about how you treat each other. You stand your ground and don’t compromise. You hurt your partner an....

I’ve run a few Facebook ads before, never spending more than a couple bucks and never with much success - either in terms of views, likes, or clicks. Inspired by this blog post on MerchInformer.com , I decided to expand my audience beyond the United States.

Even though Gabe and I sometimes have slightly differing views on the iPad’s productivity value compared to the Mac, with his latest post , I think we are completely in sync—metaphorical Chris Farley falls and all. In particular, he nails a massive friction point for me with the iPad: I can type more comfortably on my iPhone than I can with my iPad Pro on the couch, in bed, or even just reclined in the backyard. I’m sure there’s a go....

As a fun side project to distract me from my abysmal progress on my book, I decided to play around with the math genealogy graph! For those who don’t know, since 1996, mathematicians, starting with the labor of Harry Coonce et al, have been managing a database of all mathematicians. More specifically, they’ve been keeping track of who everyone’s thesis advisors and subsequent students were. The result is a directed graph (with a current est..

Disclaimer: I don’t advocate using Vim seriously as your primary development environment. As powerful as it is, Vim remains a text editor, not an IDE . I ran into some Xcode problems the other day where I lost syntax highlighting and code completion in Swift files. What should we do when Xcode just doesn’t work? I joked that at this point, it might be easier to just use Vim for my Swift development. Well… ....

Tim Cook’s entire commencement address to the MIT class of 2017 is an instant classic, but this is the part I want to echo forever: Technology is capable of doing great things. But it doesn’t want to do great things. It doesn’t want anything. That part takes all of us. It takes our values and our commitment to our families and our neighbors and our communities. Our love of beauty and belief that all of our faiths are interconnected. O..

I found the tensorflow documentation rather lacking for installation instructions, especially in regards to getting GPU support. I’m going to write down my notes from wrangling with the installation here for future reference and hopefully this helps someone else too. This will invariably go out-of-date at some point, so be mindful of the publish date of this post. Make sure to cross-reference other documentation that has more up-to-dat....

Once upon a time, we had a single monolith of software, one mothership running everything. At SoundCloud, the proliferation of microservices came from moving functionality out of the mothership. There are plenty of benefits to splitting up features in this way. We want the same benefits for our data as well, by defining ownership of datasets and ensuring that the right teams own the right datasets.

PCs lead us indoors. Smartphones lead us into isolation. The Apple Watch is—sort-of—leading us back out into the real world again by encouraging movement, keeping phones in pockets, and most importantly, looking up again . I’ve owned an Apple Watch since the Series 0 started shipped 26 months ago. I can’t imagine ever not owning one again. Actually I can, but only when some higher form of “wearable” supersedes the form of a wrist watch....
