Q&A site Stack Overflow has answer to nagging question … about Stack Overflow

A systems administrator was showering the other day (maybe not literally) when he had this thought: “I’ve never actually seen Stack Overflow’s front page. I wonder what percentage of their traffic requests are to simply http://stackoverflow.com.”As with any knowledge market – and news sites such as this one – most of the traffic to Stack Overflow would be assumed to arrive at addresses other than its homepage. The wondering here was about details. And no one need wonder any longer, as stepping up to the plate is Nick Craver, Stack Overflow Architecture Lead: Someone poked me for an answer here so here's some data:To read this article in full or to leave a comment, please click here

Worth Reading: Bouncing back to private clouds

There is an adage, not quite yet old, suggesting that compute is free but storage is not. Perhaps a more accurate and, as far as public clouds are concerned, apt adaptation of this saying might be that computing and storage are free, and so are inbound networking within a region, but moving data across regions in a public cloud is brutally expensive, and it is even more costly spanning regions. —The Next Platform

An enterprise IT pro’s guide to Mixpanel analytics

Relax, Mixpanel’s sales people probably aren’t going to pester you if you’re an enterprise IT pro. You’re not the target customer for this San Francisco-based provider of cloud-based analytics tools. But that doesn’t mean Mixpanel shouldn’t at least be on your radar since there’s a good chance you’re supporting people within your organization who might be using Mixpanel – we’re talking engineers, designers and other product development team members who want to get a better view of how their products are actually being used and received.MORE: 15 big data and analytics companies to watchTo read this article in full or to leave a comment, please click here

Assange: CIA had lost control of its cyberweapon documents

Information about purported CIA cyberattacks was "passed around" among members of the U.S. intelligence community and contractors before it was published by WikiLeaks this week, Julian Assange says.The CIA "lost control of its entire cyberweapons arsenal," the WikiLeaks editor in chief said during a press conference Thursday. "This is a historic act of devastating incompetence, to have created such an arsenal and stored all in one place and not secured it."Assange declined to name the source who gave the information to WikiLeaks, but he seemed to suggest the 8,700-plus documents, purportedly from an isolated CIA server, came from an insider source.To read this article in full or to leave a comment, please click here

Texas hospital struggles to make IBM’s Watson cure cancer

If IBM is looking for a new application for its Watson machine learning tools, it might consider putting health care providers' procurement and systems integration woes ahead of curing cancer.After spending more than four years and US$62 million on its Oncology Expert Advisor project, the M.D. Anderson Cancer Center at the University of Texas still looking for answers in all those areas.The fall-out from that project has now prompted the resignation of the cancer center's president, Ronald DePinho, the Wall Street Journal reported Thursday.To read this article in full or to leave a comment, please click here

IDG Contributor Network: Basic training: Cybersecurity lessons inspired by an opportunistic developer

Today, not only do we see a significant increase in the number of cyber attacks, but by design the incidents are also more fearless and larger in their scale and impact to the business. According to Cisco, the frequency of distributed denial of service (DDoS) attacks has increased more than 2.5 times since 2013, with the current average DDoS attack large enough to take many organizations completely offline.RELATED: Machine learning offers new hope against cyber attacks Most businesses have cybersecurity initiatives, but how can we be sure the policies and people are keeping pace with the threats that are becoming more dynamic as technology progresses? TechRepublic reported that an estimated 90 million cyber attacks occurred in 2016, which means 400 attacks every minute. As data travels through a virtual ecosystem, security must extend beyond the device itself. To read this article in full or to leave a comment, please click here

Building Reliability

Systems are inherently reliable. Until they aren’t. On a long enough timeline, even the most reliable system will eventually fail. How you manage that failure says a lot about the way your build your system or application. So, why is it then that we’re so focused on failing?

Ten Feet Tall And Bulletproof

No system is infallible. Networks go down. Cloud services get knocked offline. Even Facebook, which represents “the Internet” for a large number of people, has days when it’s unreachable. When we examine these outages, we often find issues at the core of the system that cause services to be unreachable. In the most recent case of Amazon’s cloud system, it was a typo in a script that executed faster than it could be stopped.

It could also be a failure of the system to anticipate increased loads when minor failures happen. If systems aren’t built to take on additional load when the worst happens, you’re going to see bigger outages. That is a particular thorn in the side of large cloud providers like Amazon and Google. It’s also something that network architects need to be aware of when building redundant pathways to handle problems.

Astro is an AI-powered email client with big dreams

If there’s one source of technological frustration at work, it’s email. Getting a job done often still relies on sending chains of messages back and forth to the extent that it would be nice to have an assistant to help deal with it all.That’s the idea behind Astro, a new app that applies artificial intelligence to email in an attempt to make life easier for its users. Its marquee feature is Astrobot, a chatbot powered by machine learning that’s designed to keep users abreast of what’s important in their inbox.For example, Astrobot will read through users’ emails and notify them when they’ve been asked important questions. It can also be used to unsubscribe from emails, clean out a user’s inbox and more. That functionality sits on top of a solid, modern email client, which entered public beta on Mac and iOS Thursday.To read this article in full or to leave a comment, please click here

IDG Contributor Network: Recent Amazon outage highlights need for cloud automation

As most internet users are aware, last week Amazon faced one of its largest service outages since the launch of Amazon Web Services (AWS). The list of disrupted businesses read like a dire who's who of the internet, from Netflix to Pinterest to Airbnb. The cause of the AWS S3 outage appears to be a fat-finger typo by an authorized Amazon system administrator who was troubleshooting an unrelated problem.It happens, and it happens often.According to research from Ponemon Institute in 2016, at least 22 percent of data center outages each year are caused by human error. Outages have far-ranging impacts, from business disruption and lost revenue, to end user productivity. The average cost of an outage has increased by 38 percent since 2010 from $505,502 to $740,357 in 2016.To read this article in full or to leave a comment, please click here

IBM technology moves even closer to human speech recognition parity

IBM this week said its speech recognition system set an industry record of 5.5% word error rate, a percentage that lets a computer understand human conversation almost as well as the average person does.According to IBM human parity was considered a 5.9% word error rate but IBM who partnered with Appen, a speech and technology service provider, reassessed the industry benchmark and determined that human parity is lower than what anyone has yet achieved: 5.1%.+More on Network World: Gartner: Artificial intelligence, algorithms and smart software at the heart of big network changes+To read this article in full or to leave a comment, please click here

Review: QNAP TVS-882T NAS piles on the features

We’ve seen a steady flow of multifunction NAS boxes over the years. What began as relatively straightforward uses of Linux software RAID and mildly customized hardware has blossomed into a crop of multifaceted appliances that sport a full-on rampage of capabilities. In some cases, the NAS functionality may be one of the more minor considerations. QNAP’s TVS-882T is a prime example of this new class of NAS.To read this article in full or to leave a comment, please click here(Insider Story)
