Using the iPad Pro made for some confused moments when reaching for a mouse that wasn’t there, but I quite quickly became accustomed to mashing the screen instead of rolling a rodent. I found the touch screen is not a precise instrument for selecting an edit point in text and therefore a little frustrating compared to a mouse. Over time I found I can live with it.I don’t like to write directly into The Reg’s CMS, because it is a web app and I worry about losing work with a fat-fingered mistake. So I write in a word processor and then copy and paste into the CMS.That’s a bit tricky in the iPad Pro, and rather slower than using a mouse. On the upside, iOS now has just enough filesystem so it’s easy to save into Dropbox, Google Drive or OneDrive. And also easy to find files and do things like send them as attachments.Writing Reg stories and loading them into our CMS requires simple tools and processes.When Apple familiarised me with the iPad Pro (Cupertino doesn't just shove kit into a courier bag and let you start playing alone) it mentioned that the device really shines when you run apps built for a touch interface. Those apps also make use of the Pencil, which I've tried and found just doesn't fit into my workflows.

For now, it's clear that the iPad Pro and Smart Keyboard is a very, very capable mobile device that offers exceptional convenience to travellers and can do a job for simple content creation.But I must confess I couldn't stop myself reaching for the laptop when assembling a photograph-heavy story, and had to force myself to use the iPad for the photographs it contains as my instinct was to use my phone.“Lappability”, for me, therefore did not translate into easy ubiquity. At least at nine inches. But the iPad Pro can clearly do a job for many mobile workers, who will find it an elegant and reliable tool. Developing and deploying software is too hard, according to Chef co-founder and CTO Adam Jacob. An application may work fine on a developer's laptop or as a prototype on a single VM (virtual machine).However, if you want to run a production environment across thousands of servers, it gets significantly harder. Most of what's hard about it is about, how do I build the application that goes in the virtual machine? How do I build the virtual machine image? How do I orchestrate the way to deploy? How do I know that deployment is safe? How do I handle dynamic topology? How do I do service discovery, if my application depends on 15 other services for it to run? How do you know where they are? How do you update them? Those are the sorts of problems that are intractable, he told The Register.

His solution is Habitat, which went public today under the Apache license.What is Habitat? The core concept is that instead of deploying applications as-is, you deploy them as packages that are managed by a Habitat supervisor. A Habitat package includes the software and all its dependencies and configuration options. The supervisor manages the lifecycle of the package for which it is responsible, and is able to start, stop and update it. Habitat supervisors can be linked to form rings, which are groups of services. Habitat is agnostic about where it runs, which could be in a container or on a VM or on a physical server.The Habitat command line tool lets you build and install packages. It is most at home on Linux, but also works on Mac OS X in conjunction with Docker Toolbox, which creates a Docker environment on a Mac. A Windows version is on the way.We're going to work closely with Microsoft to get the Windows port of Habitat so that you can write Windows native apps and run them under the Habitat supervisor, said Jacob.The software in a package is ideally built from source, but can also be a proprietary binary. Habitat records all the dependencies and version information in a manifest. You also include configuration files in a language called TOML (it stands for Tom's Obvious, Minimal Language).

Using Habitat, all the behavior of the application through its entire lifecycle lives with the application itself as it moves through the lifecycle. It doesn't need any other system in order to behave correctly. So if you deploy the application and it's using Habitat, and you put it on bare metal, you manage it the same way you would manage it if you deployed that application on Cloud Foundry, or if you deployed it on Docker, or Mesos, or Kubernetes, said Jacob.The capabilities of Habitat supervisors, when linked, include dynamic configuration of services, called topologies. An example would be, you have a database. And you need to have one leader and lots of followers, so you're replicating all the data that comes into the database. The supervisor can manage that for you without you having to do anything. You don't have to deploy a configuration management server, or service discovery, or a deployment orchestration engine, or any of those things. You just tell the supervisor: this service runs in this topology, and it just works, Jacob told The Reg. As you deploy the application, you are also deploying the automation.

Is Habitat middleware? We describe it as application automation because we think that is the best possible fit for what it is. In a way it's middleware. It provides a bunch of services that an application can use. What's very different is that traditionally, you write the application for the middleware. That's backwards from Habitat. Habitat wraps around your application as it is. It's actually a new way of solving the problem, said Jacob.Habitat itself is written mostly in Rust, a systems programming language created by Mozilla. It makes some really great guarantees about safety. And it has no runtime, so it allows the supervisor itself to be very small. We love Rust, Jacob said.The most telling part of my conversation with Jacob came toward the end, when I asked what benefit Habitat brings to those who have already embraced fully automated application delivery.If you've gone through the trouble to understand how to do it the hard way, Habitat is like doing that in easy mode, he said. It sounds like a confession that doing DevOps right is currently too difficult.The project has initial support from others including Intel, Mesosphere and CoreOS. Future plans include an automated public build service as well as extending Habitat to cover more scenarios and platforms. An intriguing project, which you can check out here.

NASA has deliberately set a fire inside a Cygnus spacecraft, after detaching from the International Space Station (ISS) for safety reasons.The capsule is carrying the Spacecraft Fire Experiment, which has ignited a variety of materials to study how they burn and spread in microgravity. The purpose is to help protect future missions from the possibility of burning up while the nearest fire department is millions of miles away.NASA reports that the experiment is burning nicely and has traveled 1,000 miles in space so far. When NASA is sure it's received all the data it can from the tests the whole lot will be pushed earthward for fiery disposal. It is with incredible sadness that El Reg must report that Lester Haines, one of our finest story-tellers and an all-round good bloke, passed away on Monday. We have published his obituary, The Life and Times of Lester Haines.Lester, who was 55, died of a heart attack at his home in Spain. He will be cremated on Friday 17 June.Readers will know Lester for his biting wit, his piloting of the Special Projects Bureau – including the PARIS and LOHAN projects – and his wonderful recreations of real-world events through the medium of PlayMobil.

Lester joined The Register in 2000 to manage merchandising and photography but grabbed the nearest laptop and wrote his first article in September that year, about one of our own defecting to the dark side – or PR, as it is otherwise known.Among the 7,300 stories Lester produced for El Reg were regular features including Logo Watch, Strategy Boutique, Rise of the Machines, and Flame of the Week.It didn't get any airtime at the big opening day of the annual Apple Worldwide Developers Conference (WWDC), but excitement is building around Apple's next-generation file system.Early specs show the system will bring your hard drive into the modern era, most notably by supporting native encryption. It will also time-stamp files by nanoseconds (rather than seconds), making it better for modern databases, and take snapshots of the file system, massively reducing the time needed to make backups.Other interesting features include crash protection, space sharing – which will enable much more flexible partitioning – optimization for solid-state hard drives, and a better system for cleaning up deleted files.In short, the new Apple File System (APFS) can be expected to bring significant advances in speed and efficiency, and the updating of Apple's file sharing technology, which hasn't changed in nearly 20 years (others, of course, have developed more modern systems that are now 10 years old).

APFS' preliminary information has been released to developers, and sessions on it will take place this week at WWDC. It is scheduled to ship sometime in 2017, meaning that the company may be able to boast big performance improvements in its products toward the end of that year. It is designed to work with all of Apple's operating systems – iOS, watchOS, tvOS and macOS.There is still a lot of work to be done, however. It is not currently possible to start your computer directly with the file system, and it doesn't work with Apple's current encryption and archiving systems – presumably because it is intended to replace them.The file system is also case-sensitive and that apparently cannot be disabled, which will lead to all sorts of knock-on compatibility issues. Yep, you will have to buy more Apple gear: a new watch to go with your new phone to sync with your new laptop. Apple is always looking after that bottom line.Support documents published by 9to5Mac indicated the platform will be rebranded macOS, the name of the Mac’s original OS when it launched in 1984, one of four Apple platforms. The others are watchOS, tvOS and iOS.

9to5Mac later updated its story to say Apple had changed its pages back to read Mac OS X.The workstation NeXTSTEP 1.0 was originally unveiled in 1988, before going cross platform.Apple acquired NeXT in a reverse takeover that brought Steve Jobs back to the company he founded, and the platform was revamped extensively before launching as Mac OS X in 2001. Presumably, Apple now reckons it's so long (15 years) since the last release of the original MacOS, no confusion will be created.USB-C and Thunderbolt are the last mainstream connections devices will need to the outside world, according to analyst firm ABI Research.The company's new Device Connectivity Report predicts that by the year 2020 “Almost half of the smartphones and 93% of laptops will include USB Type-C connectivity.” In coming years we'll also see gadget-makers will offer “fewer connectivity types and ports per device as the industry steadily transitions toward wireless solutions and cable-free devices.”ABI analyst Andrew Zigani opines that “USB-Type C and Thunderbolt 3.0 will be the last major physical ports to gain major significance and mainstream traction.”Next up? Wi-Gig, aka 802.11ad, which has already made it on to some business laptop vendors' feature lists for 2016 and is expected to become more common in coming years. WiGig can handle video traffic to displays or general purpose data. WiGig Docks are starting to emerge, but before long it's expected the standard will appear in devices like televisions, projectors and monitors.

Of course there are untold millions of such devices out there, most of which are good for years more use. Further, nobody is suggesting wireless charging pads are going to become so ubiquitous that we can all do without mains connections. So chances are gadgets will need at least one physical port for the foreseeable future.But Zignani reckons there's no need for the industry to consider mainstream connectors beyond USB-C and Thunderbolt 3.0. And seeing as Intel last year decided it's happy for the USB-C port to handle Thunderbolt traffic, rather than its own physical port design, we're on track for a single standard hole for most portable devices any year now.Special report In Australia and New Zealand, hackers are doing it for themselves by creating vibrant security conferences that run on their own terms and actively avoid the corporate-speak and fear-mongering that characterises so many vendor-led events.These conferences, or cons, are booming and showcase security skills that rival the best the global security industry can offer.The hacker-run conferences are nothing like commercial technology confabs: vendor pitches are universally banned, so are trade show booths. Bars replace bain maries full of conference casseroles and black metal-inspired custom shirts are the de facto uniform.At these events hackers reveal holes in the world's most popular technology and public transport systems to a soundtrack of sweeping moans of derision, laughter, and, for some cons, bursts of on-stage pyrotechnics.Most hacker presenters follow the modern line and push the companies they hack to fix holes ahead of their on-stage disclosures, yet blasé promises to fix earn retribution as zero-days are still dropped.
