Docker Online Meetup #42: Docker Captains Share Tips & Tricks for Using Docker 1.12

For this week’s Docker Online Meetup, Docker Captains Ajeet Singh Raina, Viktor Farcic and Bret Fisher shared their tips and tricks for built In Docker orchestration.

Ajeet talked about the best ways to use Docker 1.12 Service Discovery and shared key takeaways. Viktor talked about best practices for setting a Swarm cluster and integrating it with HAProxy. Bret concluded the meetup with a presentation on Docker 1.12 command options and aliases including cli aliases for quick container management; the shortest path to secure production-ready swarm; how to use cli filters for easier management of larger swarms; and docker remote cli security setup.

Knowing what to showcase on your resume

Resumes aren't easy for anyone. And James Park was no different. Park works with the Information Systems and Control Association (ISACA) and recently earned his master's degree. While his career his distinguished, his resume needed some work. After speaking with the candidate, Laura Smith-Proulx, award winning resume writer and author of three books (How to Get Hired Faster, Solve Your Toughest Resume Challenges and Finding Your Next Job with LinkedIn), knew there was far more to Park's career history than his resume suggested.To read this article in full or to leave a comment, please click here(Insider Story)

3 new programming languages: What their creators say

With hundreds of programming languages already in existence, why invest the considerable effort in creating a new one? For developers of three newfangled open source languages -- Coconut, Crystal, and Oden -- the answer is simply that, in programming, there are always new niches to fill and new needs to be met.Scratching the proverbial itch and unwilling to settle for existing tools that they found somewhat lacking, these developers set out to build their own languages, driven by specific goals. For Coconut, which compiles to Python, it’s all about bringing functional programming to the Python language. Crystal is devoted to combining multiple programming capabilities. And the driving force behind the development of Oden is filling in some capabilities absent from Google’s popular Go language.To read this article in full or to leave a comment, please click here

Microsoft delays Sunrise calendar’s death to bring more features to Outlook

At the 11th hour, the popular Sunrise calendar app’s execution has been stayed—though not permanently.Microsoft purchased Sunrise’s parent company in February 2015 to bolster Outlook’s capabilities. And in a post last October, Microsoft confirmed plans to kill Sunrise, though it promised that “We will leave Sunrise in market until its features are fully integrated into Outlook, the exact timing of which we will communicate in advance.” This past March, the Sunrise blog confirmed that the app would be shut down completely on August 31.To read this article in full or to leave a comment, please click here

CPU, GPU Put to Deep Learning Framework Test

In the last couple of years, we have examined how deep learning shops are thinking about hardware. From GPU acceleration, to CPU-only approaches, and of course, FPGAs, custom ASICs, and other devices, there are a range of options—but these are still early days. The algorithmic platforms for deep learning are still evolving and it is incumbent on hardware to keep up. Accordingly, we have been seeing more benchmarking efforts of various approaches from the research community.

This week yielded a new benchmark effort comparing various deep learning frameworks on a short list of CPU and …

Toshiba hopes cloudless smartphone backup will have a bright future

What will back up all the data on your smartphone, but doesn't physically exist? No, it's not another cloud backup service, it's the centerpiece of Toshiba Storage Peripherals' booth at IFA.The as-yet-unnamed (and unfinished) product will be about the size of a small plate, to judge by the prototype in a glass case on the booth. It will have a USB connection to charge your smartphone and back up its contents to an included 500 GB hard disk. There will be no cloud servers involved, and no internet connection needed: Everything will stay inside the device, said Toshiba's product manager for hard disks, Eun-Kyung Hong."This is for home backup where you know all your data is in your home, not in the cloud where you don't know whether it's secure or not," she said.To read this article in full or to leave a comment, please click here

Why your smartphone is sicker than a room full of snotty toddlers

If you thought your smartphone was safe(r) from the wild west of malware, spyware and other viruses compared with the PC space, think again. A new report from Nokia proclaims a “sharp rise in the occurrence of smartphone malware infections” in the first half of 2016. Taking the big hit are smartphone infections, which now account for 78% of all infections across the mobile network, says Nokia in its latest Nokia Threat Intelligence Report. The report is compiled by the company’s Threat Intelligence Lab, which aggregates anonymous data across global mobile networks using its Nokia NetGuard Endpoint Security product. Along with traffic monitor that detects malware command-and-control traffic and exploit attempts (among other attacks), the lab also keeps a database of the latest malware to analyze how attacks occur.To read this article in full or to leave a comment, please click here(Insider Story)

Using guestfish to modify VM disk image

EarIier I wrote about some ways to modify VM disk images used by Unetlab. Basically it boils down to running a VM, console to it and change things through its shell. Obviously, this approach is no way near a handy way to do small changes like: loading basic config adding license files In this post I will talk

IDG Contributor Network: The 8 fallacies of distributed computing are becoming irrelevant

In 1969, the U.S. Department of Defense created ARPANET, the precursor to today’s internet. Around the same time, the SWIFT protocol used for money transfers was also established. These are both early examples of distributed systems: a collection of independent computers that appear to users as a single coherent system.Many come to know they have a distributed system when the crash of a computer they’ve never heard of affects the whole system. This is often the result of assumptions architects and designers of distribution systems are likely to make.In 1994, Peter Deutsch, who worked at Sun Microsystems, wrote about these assumptions to explore what can go wrong in distributed systems. In 1997, James Gosling added to this list to create what is commonly known as the eight fallacies of distributed computing. Traditional approaches, which use time-based replication to architect and build distributed systems, suffer from many of these fallacies and result in systems that are inefficient, insecure and costly to maintain. Modern approaches, using complex mathematics such as the Paxos algorithm, overcome many of these significant hurdles.To read this article in full or to leave a comment, please click here
