The Essence Of Multi-Threaded Applications

In the prior two articles in this series, we have gone through the theory behind programming multi-threaded applications, with the management of shared memory being accessed by multiple threads, and of even creating those threads in the first place. Now, we need to put one such multi-threaded application together and see how it works. You will find that the pieces fall together remarkably easily.

If we wanted to build a parallel application using multiple threads, we would likely first think of one where we split up a loop amongst the threads. We will be looking at such later in a …

SDxE: Engineer Focused

As an engineer, you’ve probably asked yourself a thousand times—what does all this software defined stuff mean for me? Answers are out there, of course; it seems like everyone is writing about it. Some of the answers out there are even useful, of course, but some of them are not. Most folks writing about the software defined craze are either unrealistic, or they’re focused on the large scale network you probably aren’t working on. Which leaves the question lingering: how does software defined apply to me?

SDxE—Software Defined Enterprise—is a new show designed to answer those questions for the engineer. I’ll be there; the full schedule isn’t in place, but I am currently pulling together a panel about the end of the (appliance) router. I plan to have folks from Cumulus, 6Wind, and at least one independent expert (Jeff Tantsura), sitting down to chat with me about disaggregation and the future of the router market. Specifically, are the tools in place that will allow you, the average engineer, running the “average” “enterprise” network, to take advantage of disaggregation?

Shawn Zandi will be there discussing the LinkedIn data center, and Pete Lumbis will be there talking about network automation. Continue reading

AI should enhance, not replace, humans, say CEOs of IBM and Microsoft

Artificial intelligence should enhance human workers, not replace them, at least according to the CEOs of IBM and Microsoft.Ginny Rometty and Satya Nadella made clear their view of the role of AI in a panel discussion at the World Economic Forum in Davos, Switzerland, on Tuesday, just a few hours after Rometty circulated IBM's three guiding principles for the development of cognitive technologies to company staff.Less dramatic and snappily expressed than Isaac Asimov's three laws of robotics, IBM's three principles are nevertheless intended to limit the harm the introduction of AI technologies causes.The first thing to understand is the purpose of these technologies. For IBM, Rometty said, "it will not be man or machine: Our purpose is to augment and be in service of what humans do."To read this article in full or to leave a comment, please click here

Report: Samsung probe blames Galaxy Note7 fires on faulty batteries

After months of recalls, scares, and device-killing software updates, Samsung is finally ready to reveal the results of its investigation into the exploding Galaxy Note7s. According to a report from Reuters, the electronics giant will detail its findings on Jan. 23, and to the surprise of no one, it has concluded that the battery is the culprit.To read this article in full or to leave a comment, please click here

Public Spectrum for Public Access

An extraordinary moment has arrived in the evolution of the internet. For all the transformation that has occurred over the 20+ years since the arrival of the World Wide Web and for the billions of people whose economic, civic and social circumstances have been improved, most people remain without internet connections.

Residing in every country, these unconnected billions still wait for affordable meaningful access to this essential service. Without access to the internet, people cannot even begin to participate in the global digital economy.

Sensitive access tokens and keys found in hundreds of Android apps

Many developers still embed sensitive access tokens and API keys into their mobile applications, putting data and other assets stored on various third-party services at risk.A new study performed by cybersecurity firm Fallible on 16,000 Android applications revealed that about 2,500 had some type of secret credential hard-coded into them. The apps were scanned with an online tool released by the company in November.Hard-coding access keys for third-party services into apps can be justified when the access they provide is limited in scope. However, in some cases, developers include keys that unlock access to sensitive data or systems that can be abused.To read this article in full or to leave a comment, please click here

Terrorists are winning the digital arms race, experts say

Terrorist groups are embracing a huge number of digital tools to recruit members and plan attacks, putting them a step ahead of governments trying to combat them, a group of counterterrorism experts said.Twitter removed about 250,000 accounts connected with ISIS in one year, but the terrorist group uses 90 other social media platforms, Rob Wainwright, the director of Europol said Tuesday. Terrorist groups have begun to live stream their attacks, and they are using the internet to launch "innovative crowdfunding" campaigns, he said at the World Economic Forum in Davos-Klosters, Switzerland."The technology is advanced," Wainwright added. "They know what to do, and they know how to use it."To read this article in full or to leave a comment, please click here

Endpoint Security in 2017

Just a few years ago, there were about 6 to 10 well regarded AV vendors that dominated the market.  Fast forward to 2017 and my colleague Doug Cahill and I are currently tracking around 50 endpoint security vendors. Why has this market changed so much in such a short timeframe?  New types of targeted threats regularly circumvented signature-based AV software over the past few years.  This weakness led to system compromises, data breaches, and panicky CISOs in search of AV alternatives.  This in turn persuaded the fat cats on Sand Hill Rd. to throw VC dollars at anything that hinted at endpoint security innovation.Okay, I get the need for more than signature-based AV but there simply isn’t room in the market for 50 endpoint security vendors.  Thus, it’s safe to assume a lot of M&A activity and outright business failures this year. To read this article in full or to leave a comment, please click here

Adapting InfiniBand for High Performance Cloud Computing

When it comes to low-latency interconnects for high performance computing, InfiniBand immediately springs to mind. On the most recent Top 500 list, over 37% of systems used some form of InfiniBand – the highest representation of any interconnect family. Since 2009, InfiniBand has occupied between 30 and 51 percent of every Top 500 list.

But when you look to the clouds, InfiniBand is hard to find. Of the three major public cloud offerings (Amazon Web Services, Google Cloud, and Microsoft Azure), only Azure currently has an InfiniBand offering. Some smaller players do as well (Profit Bricks, for example), but it’s …

Wouldn’t it be nice if everyone knew a little queuing theory?

After many days of rain one lane of this two lane road collapsed into the canyon. It's been out for a month and it will be many more months before it will be fixed. Thanks to Google maps way too many drivers take this once sleepy local road. 

How do you think drivers go through this chokepoint? 

 

 

One hundred experience points to you if you answered one at a time.

One at a time! Through a half-duplex pipe following a first in first out discipline takes forever!

Yes, there is a stop sign. And people default to this mode because it appeals to our innate sense of fairness. What could be fairer than alternating one at a time?

The problem is it's stupid.

While waiting, stewing, growing angrier, I often think if people just knew a little queueing theory we could all be on our way a lot faster.

We can't make the pipe full duplex, so that's out. Let's assume there's no priority involved, vehicles are roughly the same size and take roughly the same time to transit the network. Then what do you do?

Why can't people figure out its faster to drive through Continue reading
