Tech Bytes: Nation-Wide Dentistry Network Chooses Integrated SD-WAN, SD-Branch, Security With Fortinet (Sponsored)
Today’s Tech Bytes, sponsored by Fortinet, explores an SD-WAN deployment with Smile Brands, a nation-wide network of dental practices. Smile Brands started with one SD-WAN product and then switched to an integrated security, SD-WAN, and SD-Branch solution with Fortinet. Our guest is Brett Stetzko, Senior Network Engineer at Smile Brands.Tech Bytes: Nation-Wide Dentistry Network Chooses Integrated SD-WAN, SD-Branch, Security With Fortinet (Sponsored)

COVID-19 Cyberthreat and Malware Updates
It has been over three months since our last report on COVID-19–themed attacks [1]. During this period, the tragedy of the COVID-19 pandemic has continued to dominate our daily livesfe. On the digital virus side, sSince our lastthat report [1, ] we’ have been closely tracking the cyberthreat landscape that leveraging leverages the COVID-19 themes. In the last report, we discovered that the majority of the attacks were involved infostealers. The oIn observations made from over the past two months, witnessed similar infostealers1 as reported in [ again played a key role1]. HoweverIn the meanwhile, we also detected other threats not that we hadn’t seen earlier, such as the Emotet campaign and remote access Trojan (RAT) attacks.
In this blog post, we first present the our most recent telemetry data, as reported by some VMware customers,, in order to exhibit highlight the diversity and magnitude of the attacks. Next, we investigate the Emotet campaign, as it is the most dominant wave seen in this period. More specifically, we analyze one of the samples from the campaign to reveal the tactics, techniques, and procedures (TTPs) used in the attack, and discuss how the Emotet payload variant is different from the one we reported recently [2].2

Technical Debt (or Is Future Proofing Even a Good Idea?)
What, really, is “technical debt?” It’s tempting to say “anything legacy,” but then why do we need a new phrase to describe “legacy stuff?” Even the prejudice against legacy stuff isn’t all that rational when you think about it. Something that’s old might also just be well-tested, or well-worn but still serviceable. Let’s try another tack.
Technical debt, in the software world, can be defined as working on a piece of software for long periods of time by only adding features, and never refactoring or reorganizing the code to meet current conditions. The general idea is that as new features are added on top of the old, two things happen. First, the old stuff becomes a sort of opaque box that no-one understands. Second, the stuff being added to the old increasingly relies on public behavior that might be subject to unintended consequences or leaky abstractions.
To resolve this problem in the software world, software is “refactored.” In refactoring, every use of a public API is examined, including what information is being drawn out, or what the expected inputs and outputs are. The old code is then “discarded,” in a sense, and a new underlying function written Continue reading
The Week in Internet News: Facebook Considers New Ways to Combat Disinformation
More moderation: Facebook is looking at new ways to moderate posts on its site to make it more difficult for election disinformation to spread, the New York Times reports. Facebook is looking at adding more “friction,” such as an additional click or two, before users can share posts, according to insiders in the company. The new measures were expected shortly.
Millions without access: About 63 percent of rural residents in Latin America and the Caribbean – 77 million people – have little or no access to Internet services, according to a study by the Inter-American Development Bank and Microsoft, Nearshore Americas says. By comparison, about 71 percent of urban residents in the region have access to the Internet.
Bracing for regulation: Residents of Nigeria are expecting the government to move to regulate social media after recent protests, Quartz Africa on Yahoo reports. “We must regulate social media in a manner that it does not become a purveyor of fake news and hate speech,” Nigeria’s minister of information Lai Mohammed said recently. “We will not fold our arms to allow purveyors of fake news and hate speech to use the social media to destabilize the country.”

Innovative Methodologies for Freelance Writers
Whenever anyone thinks about freelancing, they just imagine someone being by the beach relaxing and doing soft work either with their laptops or their mobile devices. And actually, this is the aim of freelancing. It helps one to freely work in their comfortable places. Freelance writers also have the choice to choose exactly when they would work and when they would rest. Nothing is forcefully put on them. They live a life of choice.
Though this makes it seem like freelancers have it simple and basic, it is one of the things lots of people don’t understand in the freelancing world.
Issues Faced by Freelance Writers
One of the main issues is that freelancing isn’t a consistent job. This means you could get a lot of jobs in a week and the next month you could get nothing. Getting to a point where you’ll be constantly getting gigs is quite difficult too. There’s a lot of competition in this career choice that is quite rewarding. But it is a sensitive issue if you think about it. It can get quite frustrating too.
What Makes Things Get this Difficult?
For one to succeed in the world of freelancing, you need to Continue reading
New Content: VMware NSX-T 3.0 Update
When VMware NSX-T 3.0 came out, I planned to do an update session of the VMware NSX Technical Deep Dive webinar along the lines of what I did for AWS Networking a few weeks ago. However, it turned out that most of the new features didn’t take more than a bullet or two on an existing slide, or at most a new slide.
Covering them in a live session and then slicing-and-dicing the resulting recording simply didn’t make sense, so I updated the videos in summer 2020 (the last batch was published in early August).

Virtual consensus in Delos
Virtual consensus in Delos, Balakrishnan et al. (Facebook, Inc.), OSDI’2020
Before we dive into this paper, if you click on the link above and then download and open up the paper pdf you might notice the familiar red/orange splash of USENIX, and appreciate the fully open access. USENIX is a nonprofit organisation committed to making content and research freely available – both conference proceedings and the recorded presentations of their events. Without in-person conferences this year, income is down and events are under threat. If you want to help them, you have options to donate, become a member, or even talk to your organisation about becoming a partner, benefactor, or patron. Every little helps!
Back in 2017 the engineering team at Facebook had a problem. They needed a table store to power core control plane services, which meant strong guarantees on durability, consistency, and availability. They also needed it fast – the goal was to be in production within 6 to 9 months. While ultimately this new system should be able to take advantage of the latest advances in consensus for improved performance, that’s not realistic given a 6-9 month in-production target. So realistically all Continue reading
