The software ecosystem for ARM servers “is still shaky, there needs to be a lot more software development going on and it will take time,” says Gwennap.
Previous generations of multi-core, massively parallel, ARM based servers were one off manufacturers with their own toolsets and Linux distros. HP’s attempt to really market to this segment of the market will hopefully be substantial enough to get an Ubuntu distro that has enough Libraries and packages to make it function right out of the box. In the article it says companies are using the Proliant ARM-based system as a memcached server. I would speculate that if that’s what people want, the easier you can make that happen from an OS and app server standpoint the better. There’s a reason folks like to buy Synology and BuffaloTech NAS products and that’s the ease with which you spin them up and get a lot of storage attached in a short amount of time. If Proliant can do that for people needing quicker and more predictable page loads on their web apps, then optimize for memcached performance and make it easy to configure and put into production.
Now what, you may ask, is memcached? If you’re running a web server or a web application that requires a lot of speed so that purchases or other transactions complete and show some visual cue that it was successful, the easiest way to do that is through cacheing. The web page contents are kept in a high speed storage location separate from the actual webpage and when required will redirect, or point to the stuff that sits over in that high speed location. By swapping the high speed stored stuff for the slower stuff, you get a really good experience with the web page refreshing automagically showing your purchases in a shopping cart, or that your tax refund is on it’s way. The web site world is built on caching so we don’t see spinning watches or other indications that processing is going on in the background.
To date, this type of caching has seen different software packages do this for first Apache web servers, but now in the world of Social Media, it’s doing it for any type of web server. Whether it’s Amazon, Google or Facebook, memcached or a similar cacheing server is sending you that actual webpage as you click, submit and wait for the page to refresh. And if a data center owner like Amazon, Google and Facebook can lower the cost for each of it’s memcached servers, they can lower their operating costs for each of these cached web pages and keep everyone happy with the speed of their respective websites. Whether or not ARM-based servers see a wider application is dependent on the apps being written specifically for that chip architecture. But at least now people can point to memcached and web page acceleration as a big first win that might see wider adoption longer term.
Hats off and kudos to Consumer Reports for getting on this story as soon as they could. Measurement trumps anecdotes any and all days of the week. Here now some data and measurements regarding the bendy iPhone 6 and 6 Plus.

Consumer Reports released a new video today taking on claims of overly-flexible iPhones that have appeared online recently. Apple noted that only a handful of complaints have come in and gave journalists a look at its testing procedures. Regardless of Cupertino’s claims, Consumer Reports kept its promise to conduct testing that was a bit more scientific in nature than previous YouTube videos.
To address these claims, several different phones were tested under up to 150 pounds of pressure to see when each model would stop “snapping back” to its original shape. The devices tested were the iPhone 6 Plus, iPhone 6, iPhone 5, HTC One M8, Samsung Galaxy Note 3, and LG G3.

The SanDisk Extreme PRO UHS-I SDHC/SDXC family includes 128 GB, 256 GB and 512 GB capacities. The new 512 GB card costs $799.99 and is available now.
Interesting to finally see this form factor hit the market. These cards now are as big or bigger than the typical laptop hard drive. That’s a big deal in that any computer fortified with an SDXC card slot can have a flash based back-up store. I keep my Outlook mail archives on an a drive like this. And occasionally I use it to transfer files the way I would do with a reliable USB flash drive. And this on a laptop that already has an SSD, so I’ve got 2 tiers of this kind of storage. We’re reaching a kind of singularity in flash based storage where the chips and packaging are allowing for such small form factors, hard drives become moot. If I can stuff something this small into a slot roughly the size of a U.S. postage stamp, then why do I need an SATA or even an M.2 sized interface? Is it just for the sake of throughput and performance? That may be the only real argument.
I hope Oculus can get a shipping product out on the market soon. Perfectionism is not helping launch this market. The longer they wait, the more chance there’ll be a cheaper equally well working competitor. Pleez Oculus, release the Rift.

Oculus gave the world the first look at its new prototype Crescent Bay today at the Oculus’ Connect conference (livestream), and I got the very first hands-on demo. Crescent Bay has a faster frame rate, 360-degree head tracking, and integrated headphones, plus it’s lighter.
Oculus also announced the new Oculus Platform coming to the Samsung VR, which brings VR to a large audience through mobile apps, web browsers, and a VR content discovery channel. You can read our full story on Oculus Platform here.
CEO Brendan Iribe called Crescent Bay as big of a step up from the DK2 as the DK2 was from the DK1. This still isn’t a consumer version, but it’s getting closer.
The Crescent Bay is not an official developer kit, but instead a “feature prototype” designed to show off the future of what Oculus is doing, similar to the pre-DK2 “Crystal Cove”

As for me, when I submit comments on any publication’s website, I look for Disqus (which I have registered with using my OpenID) or straight out OpenID. Totally worth it when they want authentication and identification. It also helps tie my ID back to my WordPress blog. So it has a second knock-on effect if people want to find out more about my other writings. OpenID works and it works well, and failing that Disqus works equally well for me. No need to reinvent any wheels when it comes to logins, authentications, etc.

User login is thorny. Make it too hard, and users won’t sign up. Make it too easy, and you put users’ passwords at greater risk of being hacked.
Moving all that pain to [company]Facebook[/company] might seem like an attractive option. Facebook has been pushing its Facebook Connect service as a way you can outsource the login capability to Facebook. You let Facebook handle the databases, the passwords, and so on, and you just do some simple code to link to Facebook. And there are already more than 1 billion Facebook users, so it’s likely your users already have a log-in. What’s not to Like (bad pun intended)? What’s not to like?
Well, most web properties have two important success criteria and measures: how many new users sign on every month, and how often they come back. Once you’ve used Facebook Connect, guess…

Vector monitors for the Win!
Originally posted on Hackaday:
[fredkono] has a few vintage Atari arcade boards sitting around, and without the rest of the arcade machine – especially the XY CRT – these boards would continue to gather dust. The solution to this terrible shortage of vintage video games was to build a vector monitor from scratch. No, that doesn’t mean building a new CRT, but it does mean rewiring the yoke and building a CRT controller board for tubes salvaged from small, old TVs.
Nearly all the CRTs you’ll find at your local goodwill or surplus shop are raster displays. The CRTs used in the old Atari games were vector displays and extremely similar to the tubes found in old oscilloscopes. [fred] turned the CRT found in an old 9″ color TV into a vector monitor by rewinding the yoke.
With the tube rewired, it was only a matter of connecting the custom deflection circuit boards

In a terrific demo of the wrong technology for the Flash Memory Summit, HGST is showing a PCIe-connected Phase Change Memory device running at three million IOPS with a 1.5 microsecs read latency.
For a very long time I’ve been keenly following the IOPs ratings of newly announced flash memory devices. From the SATA->SSD generation and the most recent PCIe generation to the UltraDIMMs. Now however, this Phase Change Memory announcement has kind of pushed all those other technologies aside. While the IOPs are far above a lot of other competing technologies, that is for reads and not writes. The speed/latency of the writes is about 55 times slower than the reads. So if you want top speed on reading and not writing the data, PCM is your best choice. But 55 times slower is not bad, it puts the write speed at approximately the same speed as Multi-Level Cell (MLC) flash memory currently used in your consumer grade SSD flash drives.
Chris Mellor’s emphasis is PCM likely better suited as a competitor to UltraDIMM as a motherboard memory than a faster PCIe SSD drive. And a lot depends on the chips, glue logic and Application Specific Integrated Circuits (ASICs) on the PCIe board. HGST went to great lengths to juice the whole project by creating a bypass around the typical PCIe interfaces allowing much greater throughput overall. Without that engineering trick, it’s likely the 3M IOPs level wouldn’t have been as easily achieved. So bear in mind, this is nowhere near being a shipping product. In order to achieve that level of development it’s going to take more time to make the thing work using a commodity PCIe chipset on a commodity designed/built motherboard. But still 3M IOPs is pretty impressive.
