Vine brings its attention span-challenged videos to Xbox One

If you won't watch anything that lasts longer than six seconds but still own an Xbox One, this is your lucky day.

"Starting today, you can entertain yourself with hours of short, looping videos on the big screen with the addition of the Vine app on Xbox One," reads an Xbox Wire announcement.

Does that sound slightly dystopian to anyone else? Like, we know ya'll can't pay attention to any one thing for more too long, so just entertain yourselves with these glorified GIFs until you die!

And don't worry, you can "snap" the Xbox One Vine app next to your game or whatever else you're doing so you never have to focus on a single thing at a time, even for just six seconds.

Just kidding, Vine is cool

This is the first time Twitter-owned Vine has been tailored specifically for large screen experiences.

It lets users browse playlists, categories and channels using voice and gesture commands with Xbox One Kinect.

The app can be downloaded for free from the Xbox One app store on the console.

Vine for Xbox One is available to Xbox Live members in several dozen countries, including the US, the UK, Canada, and Australia.

Oh great, Facebook now lets you comment with stickers

Oh great, Facebook now lets you comment with stickers

Facebook made like it's 1994 when it introduced stickers (read: emoticons) in Messenger chats, and now it's making like 1995 by expanding their role on the site.

Facebook users can now add stickers to comments, which is bad news for any who'd rather just communicate with words.

Facebook's available stickers are invariably adorable and generally range from cute animals doing cute things to other cute animals doing even cuter things. There are licensed stickers from shows like Adventure Time and Power Rangers as well.

From the sticker menu, you can browse available sticker packs, all of which are free - for now at least.

Sticker Star

We've asked Facebook whether it has any plans to begin charging for sticker packs, and we'll update here if we hear back.

It would be surprising if the answer is anything other than "yes," unless that answer is "no comment," which seems more likely.

The continued popularity of emoticons on the web, in texts and basically anywhere else where they're available proves that if they are available, people will use them. Thankfully you can currently only post stickers in comments on existing posts, and not in new posts or statuses.

Just recall that there was once a time when Facebook was considered the more professional and mature option compared with Myspace and other competitors. What is it turning into now?

Interview: Flash flood: when smart storage teaches virtual machines to swim

Interview: Flash flood: when smart storage teaches virtual machines to swim

You can't accuse California-based Tintri of choosing an ill-fitting name: it literally translates to "lightning" in Irish Gaelic, which begins to make sense when you discover that the company sells a flash-centric storage solution that it claims offers powerful and fast performance at a wallet-friendly price.

Tintri was co-founded in 2008 by its President and CEO Ken Klein, and Kieran Harty, who ran engineering at VMware for seven years beforehand. While working for the virtualization giant, Harty noticed that its customers were seeing benefits from virtualization on the compute side, but less so on storage, which was proving a huge "pain point".

Tintri's main offering, VMstore, is a VMware-compatible, storage-focused rack-mount appliance that uses commodity SSDs and offers features such as 10GbE connectivity and cross-platform hypervisor support. According to Harty, the company is going after NetApp's virtualization lunch with the solution, which can scale from 100 virtual machines (VMs) to more than 100,000.

Harty reckons that Tintri's solution can "learn and adapt" to an organisation's storage needs by quite literally teaching VMs sitting on the same storage to operate alongside each other in a more efficient manner. We spoke to Harty at VMworld Europe 2014 to find out more.

TechRadar Pro: Why was storage ripe for disruption when Tintri first went to market in 2011?

Kieran Harty: Storage has been a technically very boring area for a long time. I remember the last innovation that really occured, which was back with Netapp, and then [EMC] Isilon in the early 2000s. It was really two things that were happening at once: one was what virtualization was doing to storage, and then there were the hardware innovations happening around flash memory, multi-core processors and the availability of 10-Gigabit Ethernet, which you could use instead of fibre-channel. So it was the software changes, and then the hardware changes.

TRP: Would you class your VMstore storage appliance as a hybrid solutions or all-flash array? And what's the benefit of the flash component?

KH: It includes flash and hard disk, and I would characterise it as a flash-centric solution, which is the term we use. Basically it would give you the performance of an all-flash system but with the economics of a hybrid system. So one of the things that distinguishes us is that almost all - 99% or more - of the I/O happens from flash. In a conventional hybrid system you'd get maybe 70 or 80 per cent. We think you can get the performance of an all-flash system today without having the cost of one.

TRP: Is that because the cost of flash has come down?

KH: Yes - we're using commodity flash - you probably have a flash drive in your laptop. We're using those kinds of technologies and are working around some of the limitations in software. But it's still a lot more expensive than hard disk, which is why we think that for cold data, snapshots and replicas, you actually want to store those things on hard disk as opposed to flash, while not having to worry about placement issues or anything like that.

TRP: How does VMstore handle storage differently to your competitors?

KH: We use the term that our storage is smart, sees, learns and adapts. That means that in a traditional storage environment, it's very difficult to see what's happening at the VM level. It's an incredibly common problem that people encounter within IT environments. You may have an application that's running slowly, and you don't know why.

Within traditional storage you have very little visibility as to what's happening on the storage side. In contrast, our smart storage understands virtual machines - you can see everything down to the virtual machine level and you can get end-to-end performance on an individual virtual machine. So you can see if it's the network, storage or host that's running slowly.

In such an environment, there is a very simple relationship between the application and the storage being used. In virtualised environments, you have the storage shared across different applications. People call this the I/O blender where everything is mixed up together. It makes it hard to find out whether applications are interfering with each other. In contrast, we basically restore the very simple relationship between the application and the storage using it. You can then see what's happening in your SAP application, or in your VM. That's the visibility aspect.

TRP: How does it learn and adapt?

KH: Because you have these virtual machines sitting on the same storage, they can interfere with one another, which is what people call the "noisy neighbour" problem - in other words - you're running slowly because your neighbouring VM is interfering with you. We provide each VM with its own "swimming lane", where in your swimming pool you're isolated from the rest. In our environment, we provide that same logical swim lane, meaning you don't interfere with other applications in the same system.

You may have thousands of virtual machines running in the same system, so this isn't something you can really do manually - you need the technology to help. Some of our PhDs spend their time getting the control algorithms in software to enforce those swim lanes where you have what people call "performance isolation". We can learn about the workloads running on the system and then we adapt and change the resource allocation - a bit like an operating system that's running on the storage system. This all happens automatically, and everything is tuned automatically, so you don't need to do a lot of manual interference.

TRP: How can this help reduce total cost of ownership over time?

KH: There are two cases. The first is capex - saving money in terms of how much, per VM, it costs you. In our case, the cost of a virtual machine for storage is typically in the $50 - $60 range for a desktop, for example. One of the things that's most remarkable is how much time and operational complexity it saves you.

For example, a traditional storage system may take you a couple of days of professional services to configure. Our environment is literally installable within 15 minutes by somebody who's not an expert. The problem that I alluded to earlier, of diagnosing performance problems, can take days or even weeks to diagnose with a lot of finger pointing involved between different teams. Within our environment that's do-able within seconds, so that's a huge deal.

Another aspect is replication, cloning and data management. We do that at the virtual machine level, so you can do it right down to individual virtual machines. The typical planning process for replication can take days in the best case, whereas we can do it in a few minutes and change it very easily after that. Also, while it's complex internally, people that are completely non-experts can use the environment, so it's a radically different level of simplicity. And people like it when things are simple.

TRP: Is it inevitable that we're moving toward an all-flash future?

KH: I think so - over time. But it's all down to economics. We could do a comparison with the use of disks on laptops, which appeared on smaller, more expensive systems as a boot disk, rather than a main storage disk. I think it's going to take a while. People are not prepared to pay for something that's sports car-level, but we see over time that it will become more significant.
