Calling All Switchers

Are you a switcher? That is, are you someone who has transitioned from one IT discipline to an entirely new IT discipline? Perhaps you were a storage gal for a long time, and now you’ve successfully transitioned into a networking career. Maybe you used to be a Windows admin, and now Linux is your thing. Or perhaps you were a networking guy, and now you’re coding like a madman. If this sounds like you, please read on!

If this describes you—or describes something you’re in the middle of doing—I’d love to talk to you. Please hit me on Twitter (I’m @scott_lowe), or drop me an e-mail (use [email protected], substituting the correct values). I promise it won’t take much of your time, and we can do this via whatever medium makes the most sense: e-mail, telephone, Skype, instant messaging, IRC…you let me know. I’m particularly interested in talking to folks to have made a really dramatic transition, not just moving from being a server administrator to being a virtualization administrator (let’s face it, those two roles are fairly similar).

Thanks, and I look forward to hearing from you soon!

Google patches critical media processing flaws in Android

New security patches for Google's Nexus devices address seven vulnerabilities, two of which are critical and could allow for remote code execution when handling media files.The updates, released on Monday, are part of Google's recently introduced monthly patch cycle and are available for Nexus devices running both Android 5.1 (Lollipop) and 6.0 (Marshmallow). The source code for the fixes will also be added to the Android Open Source Project (AOSP) over the next 48 hours.The most serious flaws patched in this release are tracked as CVE-2015-6608 and CVE-2015-6609, and are located in the mediaserver and libutils components of Android, respectively.

Chaos Computer Club: Apple rejected TV-streaming app because of hacking iOS talks

Despite Apple having championed privacy and encryption, and having its most profitable year yet, the company is apparently not above censoring free speech on its Apple TV platform. The Chaos Computer Club claimed that Apple rejected the CCC's TV app that would allow viewers to stream the hacking conference because researchers have previously presented talks centered on hacking iOS.To read this article in full or to leave a comment, please click here

Worth Reading: Avago buys Broadcom

If the modern datacenter has taught us anything, it is that scale matters and as it turns out it matters for the manufacturers of the devices that go into various systems in the datacenter as much as it does for those who deploy and use those systems. It is with this in mind that we ponder the implications of the $37 billion acquisition of networking and wannabe server processor maker Broadcom by the recently very acquisitive Avago Technology, a maker of chips for optical networking, server networking, and storage controllers, among other things. via the platform

How to earn the trust of millennials concerned with security

Part of a great marketing strategy includes building trust with consumers, especially with influential groups like millennials. You might also call them Generation Y or digital natives, but whatever you call them, it applies anyone born between 1980 and the early 2000s. This group is usually top of the list for companies’ brand awareness efforts, but the biggest threat to your marketing strategy lies more in your approach to cybersecurity than how much money you spend on advertising.Intercede, a company specializing in identity management and secure authentication technology, surveyed roughly 1,000 U.S .and 1,000 U.K. participants aged 16 to 35 about levels of digital trust. And the study found that millennials have suspicious attitudes and a general mistrust towards businesses. In a time where celebrities’ iCloud accounts are hacked and every few months there is another data breach, it makes sense for young people to have a general sense of uncertainty towards where their data goes and how it’s used.To read this article in full or to leave a comment, please click here

OpenStack Summit – Tokyo – 2015 – Wednesday 28th – Show Notes

It’s Tuesday, it’s 9am and most people have hangovers from the numerous evening events going on in and around Takanawa. 

The opening keynote seemed to revolve around Neutron and the great work Kyle (@mestery) has been doing as the project technical lead (PTL) of Neutron. Seriously, Neutron has the highest activity rate of all projects. Some argue that Neutron is too complicated and previous to attending the summit, rumours were rife around increasing support for simplifying Neutron to replacing it with Open Daylight. Needless to say, there are parties out there that want to see Neutron dead and claim it’s just too complicated to use.

So, to some keynote ‘framing’ figures: In 2014, 68% if OpenStack users (at least of those reporting) were making use of Neutron. Just one year later and it’s jumped to 89%! Maybe this can be attributed to OpenvSwitch and OVN, but either way, usage is increasing. This could also be attributed to new users not wanting to veer away from the popular projects.

With regards to the ever standing argument of “OpenStack isn’t ready for wide adoption”, which is self perpetuating, the guest speakers who were part of the keynotes, seemed to Continue reading

Paper: Coordination Avoidance in Distributed Databases By Peter Bailis

Peter Bailis has released the work of a lifetime, his dissertion is now available online: Coordination Avoidance in Distributed Databases.

The topic Peter is addressing is summed up nicely by his thesis statement: 

Many semantic requirements of database-backed applications can be efficiently enforced without coordination, thus improving scalability, latency, and availability.

I'd like to say I've read the entire dissertation and can offer cogent insightful analysis, but that would be a lie. Though I have watched several of Peter's videos (see Related Articles). He's doing important and interesting work, that as much University research has done, may change the future of what everyone is doing.

From the introduction:

The rise of Internet-scale geo-replicated services has led to upheaval in the design of modern data management systems. Given the availability, latency, and throughput penalties associated with classic mechanisms such as serializable transactions, a broad class of systems (e.g., “NoSQL”) has sought weaker alternatives that reduce the use of expensive coordination during system operation, often at the cost of application integrity. When can we safely forego the cost of this expensive coordination, and when must we pay the price?

In this thesis, we investigate the potential for coordination avoidance—the Continue reading

How Shopify Scales to Handle Flash Sales from Kanye West and the Superbowl

This is a guest repost by Christophe Limpalair, creator of Scale Your Code.

In this article, we take a look at methods used by Shopify to make their platform resilient. Not only is this interesting to read about, but it can also be practical and help you with your own applications.

Shopify's Scaling Challenges

Shopify, an ecommerce solution, handles about 300 million unique visitors a month, but as you'll see, these 300M people don't show up in an evenly distributed fashion.

One of their biggest challenge is what they call "flash sales". These flash sales are when tremendously popular stores sell something at a specific time.

For example, Kanye West might sell new shoes. Combined with Kim Kardashian, they have a following of 50 million people on Twitter alone.

They also have customers who advertise on the Superbowl. Because of this, they have no idea how much traffic to expect. It could be 200,000 people showing up at 3:00 for a special sale that ends within a few hours.

How does Shopify scale to these sudden increases in traffic? Even if they can't scale that well for a particular sale, how can they make sure it doesn't affect Continue reading
