While supercomputers are arguably the most exciting segment of the high performance computing market, the majority of systems deployed in any given year do not fit into this elite category. …

In the long run of the history of International Business Machines, a conglomerate established back in 1911 whose Electric Tabulating System was custom built by Herman Hollerith for the federal government in the United States for the 1890 census and then commercialized, the acquisition of Red Hat by Big Blue might, in hindsight many years from now, turn out to be the most significant of the many transitions that IBM has undergone. …

How do you make your web server as secure as possible – while using the latest open security standards? How do you ensure your web site is available to everyone across all the global network of networks that is the Internet?
For the Internet to remain open, globally-connected, trustworthy, and secure, we believe the networks and servers that make up the Internet need to be based on the latest and most secure standards coming out of the Internet Engineering Task Force (IETF).
Many web server administrators may want to support the latest standards and protocols, but they don’t know how, and don’t necessarily have the time to figure it out. It may be item #393 in a long list of to-dos. Web site administrators may not be aware of the latest open standards, or may not know why they should support these standards.
As part of our Action Plan 2020, we are launching the Open Standards Everywhere project, with a focus in 2020 on the security and availability of web servers.
The project has four main components:
Where will SD-WAN go in the coming years? Will it swallow up branch security? How about end point and mobile device management? Could it extend its reach from the branch to become the way you manage your campus network? The Packet Pushers examine those and other questions in today's Heavy Networking episode.

You may remember a three or so years ago when I famously declared that Meraki is not a good solution for enterprises. I know the folks at Meraki certainly haven’t. The profile for the hardware and services has slowly been rising inside of Cisco. More than just wireless with the requisite networking components, Meraki has now embraced security, SD-WAN, and even security cameras. They’ve moved into a lot of areas that customers have been asking about while also still trying to maintain the simplicity that Meraki is known for.
Having just finished up a Meraki presentation during Tech Field Day Extra at Cisco Live Europe, I thought it would be a good time to take a look at the progress that Meraki has been making toward embracing their enterprise customer base. I’m not entirely convinced that they’ve made it yet, but the progress is starting to look good.
The first area where Meraki is starting to really make strides is in the scalability department. This video from Tech Field Day Extra is all about new security features in the platform, specifically with firewalls. Take a quick look:
Toward the end of the video is one of Continue reading

Could FPGAs Outweigh CPUs In Compute Share? was written by Nicole Hemsoth at The Next Platform.
Seamless offloading of web app computations from mobile device to edge clouds via HTML5 web worker migration, Jeong et al., SoCC’19 [^1]
This paper caught my eye for its combination of an intriguing idea (opportunistic offload of computation from mobile devices to the edge) and the elegance of the way the web worker interface supports this use case. It’s live migration – but for web workers instead of the more usual VMs or containers.
Emerging mobile applications, such as mobile cloud gaming or augmented reality, require strict latency constraints as well as high computer power… A survey on the latency of games has reported that less than ~50ms of network latency is preferred for time-critical games, which is hard to achieve with a traditional cloud system where computing servers are located in datacenters far from clients…
So you’ve got mobile devices without the computing power needed to deliver a great experience, and cloud computing that has all the needed power that’s too far away. Edge servers are the middle ground – more compute power than a mobile device, but with latency of just a few ms. The kind of Continue reading

Unlike NixOS, Debian doesn’t have a builtin mechanism to rollback an installation to a specific point in time. However, thanks to snapshot.debian.org, a wayback machine for Debian packages, it is possible to downgrade all packages to the versions from a chosen date.
Let’s suppose we want to go back to January, 20th 2020. In
/etc/apt/sources.list.d/snapshot.list, we add a date-specific
snapshot as a source:
deb [check-valid-until=no] https://snapshot.debian.org/archive/debian/20200120T111800Z/ unstable main contrib non-free
In /etc/apt/preferences.d/snapshot.pref, we set the priority of all
packages from this source to 1001. This is above the default priority
of 500 and over 1000 to allow downgrade. See apt_preferences(5)
manual page for more details.
Package: * Pin: origin snapshot.debian.org Pin-Priority: 1001
After running apt update, we can check the result with apt policy:
$ apt policy Package files: 100 /var/lib/dpkg/status release a=now 1001 https://snapshot.debian.org/archive/debian/20200120T111800Z unstable/non-free amd64 Packages release o=Debian,a=unstable,n=sid,l=Debian,c=non-free,b=amd64 origin snapshot.debian.org 1001 https://snapshot.debian.org/archive/debian/20200120T111800Z unstable/contrib amd64 Packages release o=Debian,a=unstable,n=sid,l=Debian,c=contrib,b=amd64 origin snapshot.debian.org 1001 https://snapshot.debian.org/archive/debian/20200120T111800Z unstable/main amd64 Packages release o=Debian,a=unstable,n=sid,l=Debian,c=main,b=amd64 origin snapshot.debian.org […]
