No matter what kind of traditional HPC simulation and modeling system you have, no matter what kind of fancy new machine learning AI system you have, IBM has an appliance that it wants to sell you to help make these systems work better – and work better together if you are mixing HPC and AI. …

A virtual gap: Homeless advocates and legal groups have sued New York City for a lack of reliable Internet access in the city’s 27 homeless shelters, Reuters on WTVBam.com reports. Thousands of students living in the homeless shelters are struggling to keep up with virtual school during the COVID-19 pandemic, the plaintiffs say. The city has promised to install WiFi service in the shelters. New York City recently returned to virtual school after COVID-19 rates ticked up.
Repair it yourself: The European Parliament has voted to make it easier to repair electronic devices outside of the company that sold them, Euronews.com says. The legislation would allow independent repairs without hurting the value of the device during trade in, a move that’s a “major blow” to big device makers.
Device spying: The Singapore-based developer of smartphone application Muslim Pro, targeted at Muslim users, has denied allegations that it is selling the personal data to the U.S. military, The Straits Times reports. Developer Bitsmedia says it is immediately ending relationships with its data partners, however. Vice.com recently reported that the app was among several selling personal data to the U.S. military.

In this blog post we will discuss how we made our infrastructure DNS zone more reliable by using multiple primary nameservers to leverage our own DNS product running on our edge as well as a third-party DNS provider.
You can think of an authoritative nameserver as the source of truth for the records of a given DNS zone. When a recursive resolver wants to look up a record, it will eventually need to talk to the authoritative nameserver(s) for the zone in question. If you’d like to read more on the topic, our learning center provides some additional information.
Here’s an example of our authoritative nameservers (replacing our actual domain with example.com):
~$ dig NS example.com +short
ns1.example.com.
ns2.example.com.
ns3.example.com.
As you can see, there are three nameservers listed. You’ll notice that the nameservers happen to reside in the same zone, but they don’t have to. Those three nameservers point to six anycasted IP addresses (3 x IPv4, 3 x IPv6) announced from our edge, comprising data centers from 200+ cities around the world.
We store the hostnames for all of our machines, both the ones at the Continue reading
Open standards and the role they play are an important part of what makes the Internet the Internet. A fundamental building block of the Internet and everything it enables, open standards allow devices, services, and applications to work together across the interconnected networks that make up the Internet that we depend on every day.
In fact, every moment you are online, even just reading this blog post, you are relying on open standards such as DNS, HTTP, and TLS. They are a critical property of what we call the Internet Way of Networking.
Since its inception, the Internet Engineering Task Force (IETF) – a global community of thousands of engineers who are working each day to create and improve open standards to make the Internet work better – has been at the center of technical innovation for the global Internet. In addition to the standards themselves, the open processes and principles through which they are developed ensure the evolution of Internet technologies that meet the need of the growing number of devices and uses that empower people around the world to connect, share, learn, and more. This places the work of the IETF, and other groups focused on open Continue reading
The post The dark side of BGP community attributes appeared first on Noction.
Remember my BGP route selection rules are a clear failure of intent-based networking paradigm blog post? I wrote it almost three years ago, so maybe you want to start by rereading it…
Making long story short: every large network is a unique snowflake, and every sufficiently convoluted network architect has unique ideas of how BGP route selection should work, resulting in all sorts of crazy extended BGP communities, dozens if not hundreds of nerd knobs, and 2000+ pages of BGP documentation for a recent network operating system (no, unfortunately I’m not joking).

Seeing is believing: a client-centric specification of database isolation, Crooks et al., PODC’17.
Last week we looked at Elle, which detects isolation anomalies by setting things up so that the inner workings of the database, in the form of the direct serialization graph (DSG), can be externally recovered. Today’s paper choice, ‘Seeing is believing’ also deals with the externally observable effects of a database, in this case the return values of read operations, but instead of doing this in order to detect isolation anomalies, Crooks et al. use this perspective to create new definitions of isolation levels.
It’s one of those ideas, that once it’s pointed out to you seems incredibly obvious (a hallmark of a great idea!). Isolation guarantees are a promise that a database makes to its clients. We should therefore define them in terms of effects visible to clients – as part of the specification of the external interface offered by the database. How the database internally fulfils that contract is of no concern to the client, so long as it does. And yet, until Crooks all the definitions, including Adya’s, have been based on implementation concerns!
In theory defining isolation levels Continue reading
