CPU Management in Docker 1.13

Resource management for containers is a huge requirement for production users. Being able to run multiple containers on a single host and ensure that one container does not starve the others in terms of cpu, memory, io, or networking in an efficient way is why I like working with containers. However, cpu management for containers is still not as straightforward as what I would like. There are many different options when it comes to dealing with restricting the cpu usage for a container. With things like memory, its is very easy for people to think that , --memory 512m gives the container up to 512mb. With CPU, it’s hard for people to understand a container’s limit with the current options.

In Docker 1.13 we added a --cpus flag, which is the best tech for limiting cpu usage of a container with a sane UX that the majority of users can understand. Let’s take a look at a couple of the options in 1.12 to show why this is necessary.

There are various ways to set a cpu limit for a container. Cpu shares, cpuset, cfs quota and period are the three most common ways. We can just go Continue reading

The New IBM Glass Is Almost Half Full

It takes an incredible amount of resilience for any company to make it decades, much less more than a century, in any industry. IBM has taken big risks to create new markets, first with time clocks and meat slicers and tabulating machines early in the last century, and some decades later it created the modern computer industry with the System/360 mainframe. It survived a near-death experience in the middle 1990s when the IT industry was changing faster than it was, and now it is trying to find its footing in cognitive computing and public and private clouds as its legacy …

Open letter to Avaya management: Don’t sell the networking business

The fate of Avaya has finally been determined. It’s not being broken up, shut down or having parts stripped off it in a fire sale. Instead, Avaya filed for Chapter 11 bankruptcy to help shed the $6 billion debt load that is weighing the company down.The question for the company now is what happens next? Obviously the business will be restructured. I believe the management team will keep the call center and UC businesses intact, as they go together like “rama lama lama ka dinga da dinga dong.” But what happens to the networking business? Post restructuring the networking division might be a more attractive asset to buy because many of the things weighing it down, such as pensions and debt, won’t be an issue. Avaya could sell it, then use the money to make an acquisition that could bolster its UC and CC business.To read this article in full or to leave a comment, please click here

Worth Reading: A new propaganda agency is born

The newly created Global Engagement Center is tasked with coordinating the Federal Government’s efforts to “understand, expose, and counter foreign state and non-state propaganda and disinformation… aimed at undermining United States national security interests.” This appears to be the government’s response to the as-yet unsubstantiated claims of “Russian hacking” that allegedly stole the election. No definition of what constitutes “propaganda and disinformation” or “national security interests” is given. In practice, these words can mean anything the Center would like them to mean. —Intellectual Takeout

Google pushed developers to fix security flaws in 275,000 Android apps

Over the past two years, Google has pressured developers to patch security issues in more than 275,000 Android apps hosted on its official app store. In many cases this was done under the threat of blocking future updates to the insecure apps.Since 2014, Google has been scanning apps published on Google Play for known vulnerabilities as part of its App Security Improvement (ASI) program. Whenever a known security issue is found in an application, the developer receives an alert via email and through the Google Play Developer Console.When it started, the program only scanned apps for embedded Amazon Web Services (AWS) credentials, which was a common problem at the time. The exposure of AWS credentials can lead to serious compromises of the cloud servers used by apps to store user data and content.To read this article in full or to leave a comment, please click here

Samsung Note7 explosion revelation vs. NFL’s AFC Championship Game

Organizations can be pretty darn strategic when it comes to timing bad news announcements, typically after the market closes...on Fridays...of long weekends.I can't say whether Samsung has purposely timed its press conference to explain the cause of the Galaxy Note7 fires and explosions for a Monday morning (10AM Korea Standard Time) in Seoul, South Korea knowing that many in the US will be otherwise distracted at that time (8pm Eastern Standard Time on Sunday) by the NFL's AFC Championship Game. After all, American football is down on the list of popular sports in Korea after soccer and baseball, and the company might just want to get its press conference over first thing during the week in Seoul.To read this article in full or to leave a comment, please click here
