First Steps In The Program Model For Persistent Memory

In the previous article, we left off with the basic storage model having its objects first existing as changed in the processor’s cache, then being aged into volatile DRAM memory, often with changes first logged synchronously into I/O-based persistent storage, and later with the object’s changes proper later copied from volatile memory into persistent storage. That has been the model for what seems like forever.

With variations, that can be the storage model for Hewlett-Packard Enterprise’s The Machine as well. Since The Machine has a separate class of volatile DRAM memory along with rapidly-accessible, byte-addressable persistent memory accessible globally, the …

Review: Hot cloud-based tools for Wi-Fi hotspot management

Wi-Fi hardware vendors are coming out with new cloud-based solutions, primarily to ease the remote management of wireless networks. However, they typically only support their own hardware. Here we take a look at three cloud-based solutions that support wireless routers and access points from multiple vendors.To read this article in full or to leave a comment, please click here(Insider Story)

OpenStack’s director: Why open source cloud should be the core of your data center

Six years ago over two days engineers from Rackspace and NASA met in Austin, Texas, for the very first OpenStack Summit. Six years later, OpenStack is returning to its roots.As it does so, OpenStack has cemented itself as the dominant open source IaaS platform. But at the same time, more proprietary offerings from vendors like Amazon Web Services, Microsoft Azure and VMware still seem to reign in the broader market.+More on Network World: 15 most powerful OpenStack companies | OpenStack by the numbers: Who’s using open source clouds and for what? +To read this article in full or to leave a comment, please click here

OpenStack by the numbers: Who’s using open source clouds and for what?

The latest bi-annual survey data of OpenStack users shows a continuing march of the open source cloud software into mainstream of enterprises, but also the project’s continued challenges related to ease of deployment and management.+MORE AT NETWORK WORLD: Cool products at OpenStack Austin Summit +One thing that’s clear is that interest in OpenStack continues to grow rapidly. The project is made up of 20 million lines of code; more than 585 companies have supported OpenStack in some way, and the OpenStack Foundation counts almost 40,000 people actively engaged in the community.To read this article in full or to leave a comment, please click here

Scalability of OpenFlow Control Plane Network

This article was initially sent to my SDN mailing list. To register for SDN tips, updates, and special offers, click here.

I got an interesting question from one of my readers:

If every device talking to a centralized control plane uses an out-of-band channel to talk to the OpenFlow controller, isn’t this a scaling concern?

A year or so ago I would have said NO (arguing that the $0.02 CPU found in most networking devices is too slow to overload a controller or reasonably-fast control-plane network).

Long Distance vMotion Is A Dumpster Fire

In this screencast, I go on a rant about why long-distance vMotion is a dumpster fire. Seriously, don’t do it.

Prayer Time at the Austin Summit

A large portion of the OpenStack community is gathered in Austin this week for the Spring 2016 OpenStack Summit. As I’ve done at previous Summits (and other events), I’m offering to gather with other Christian believers for a brief time of prayer in the mornings before the sessions kick off each day.

Normally I get these arranged much earlier, so I apologize for not getting this out there sooner. That being said, if you’re a Christian and interested in gathering for a brief time of prayer, we will be meeting outside the Austin Convention Center at 8:30 am. We’ll meet along East 4th Street, on the convention center side of the Downtown Station.

Anyone is welcome to join us, but please note that this will be a distinctly Christian-focused and Christ-centered event.

You don’t need to RSVP or let me know you’ll be there; just feel free to stop by. I hope to see you there!

Personal info of all 94.3 million Mexican voters publicly exposed on Amazon

On April 14, MacKeeper security researcher Chris Vickery discovered another misconfigured MongoDB, but this time the database contained the full names, addresses, birth dates and voter registration numbers for every Mexican voter. The database containing personal information on 93.4 million Mexican voters was hosted on an Amazon cloud server with “no password or any authentication of any sort” to protect it. And it has been publicly accessible since September 2015, according to Salted Hash’s Steve Ragan; although it is unknown how many people besides Vickery accessed the records.To read this article in full or to leave a comment, please click here

Analyzing real WordPress hacking attempts

In my last few posts I’ve pondered the issue of how insecure WordPress installations have become. Here’s an interesting thing to try if you run a Wordpress site; install the 404 to 301 plugin and in its settings check the “Email notifications” option and enter an email address in the “Email address” field. Now, whenever a nonexistent URL is requested, you’ll get notified and, at least for me, it’s been pretty interesting to see how hackers attempt to enter my WordPress installations. To read this article in full or to leave a comment, please click here

Question: How did hackers steal $81 million? Answer: Pretty easily.

One of the peculiar things about computer security is how much the topic is written about and discussed (a huge amount) compared to how much is actually done (always less than you think). But what’s really peculiar is that enterprises, which you’d think would have better security than organizations in, say, the SMB space, often have serious security deficiencies. Case in point: The Bangladesh Central Bank.In February this year, hackers managed to get into the Bangladesh Central Bank’s network and acquired the bank’s SWIFT credentials, codes that authorize interbank transfers. The hackers then used the credentials four times to transfer some $81 million to various accounts in the Philippines and Sri Lanka via the New York Federal Reserve but on the fifth attempt, the hackers misspelled the receiving account’s name (they spelled “Shalika Foundation” as Shalika “Fandation”)(du’oh). To read this article in full or to leave a comment, please click here
