Worst Topics To Discuss At A Dinner Party

The holiday season is near. This means you will have to attend dinner parties. And, of course, conversations are the best way to have fun at most events.

When you interact with people at a dinner party, you can talk about various things. For example, you may want to discuss your hobbies, interests, and much more. 

However, there are some topics that you should avoid. Here are the worst topics to discuss at a dinner party.

  1. Controversial Jokes

During dinner parties, you are not banned from making jokes. However, you should avoid controversial topics at all costs. Humor is harmless and good only if it’s not very sarcastic.

Besides that, you may decide to joke about another person that is not at the event. Well, we suggest you do not. That is because the individual you’re talking to may know that person. Additionally, it is not good etiquette to talk behind someone’s back.

  1. Encouraging Someone To Eat Or Drink

Yes, we understand that at a dinner party eating is mainly the point. But of course, you should never tell someone to eat more. This is, of course, unless you’re the host. 

A person may have eaten less as Continue reading

How the Internet Really Works Part 2

I’m a little late in posting this, but I thought I’d put it out here anyway. Tomorrow I’m teaching through a three-hour webinar, How the Internet Really Works part 2. From the session description—

This training will provide short reviews of many of these systems and a deeper look at the many tools network engineers can use to discover the information they need to navigate through the DNS and routing systems on the global Internet. This training will be arranged as a set of case studies posing a problem, and then working through tools available to gather the information needed to understand the problem.

Nvidia acquires Bright Computing

Remember when Nvidia was a gaming-card vendor? That doesn’t seem all that long ago but now it’s a full-blown enterprise high-performance computing and AI company that happens to sell videogame cards - if you can actually find them.Its latest move is the acquisition of Bright Computing, a maker of Bright Cluster Manager software that controls the configuration of clustered HPC systems, including Nvidia’s own DGX servers and HGX systems made by OEMs and ODMs, plus clusters from other manufacturers. The clusters of servers are linked by high-speed networks into a single unit.[Get regularly scheduled insights by signing up for Network World newsletters.] If the deal goes through, Bright Cluster Manager will become a part of Nvidia’s Enterprise Products Group. Nvidia has no intention of keeping Bright Cluster Manager for itself, and by being a part of the Nvidia channel, it gives Bright an opportunity to expand and grow its market.To read this article in full, please click here

Full speed ahead for contested 5G, W-Fi spectrum

Recent wrangling over 5G and Wi-Fi wireless spectrum indiates the breakneck pace of new bandwidths being opoened up to broadband use will continue.The underlying issues are whether newly alloted 5G bandwidth will interfere with airplane safety and whether new unlicensed spectrum will interfere with the backhaul of communications from cell towers.[Get regularly scheduled insights by signing up for Network World newsletters.] Airlines vs. telecoms The FAA’s well-publicized worries over 5G deployments in the recently auctioned C-band frequencies center on the potential of those 5G services to interfere with radio altimeter equipment in older aircraft. A radio altimeter is an avionics device that measures the distance between the bottom of an airplane and the ground directly, using radio waves, rather than measuring the surrounding air density like barometric altimeters do. It’s a key technology for bad-weather and low-visibility landings, and the possibility of any interference with those systems is worrisome from a safety perspective.To read this article in full, please click here

IoT in 2022: IoT turns into a service

The Internet of Things has been a hyped technology for years, but the pandemic and its associated tidal wave of remote work pushed its actual use in the enterprise into overdrive. What’s more, IoT is maturing as vendors begin to sell fully functioning applications, not just the components needed for businesses to build their own.The pandemic has already driven sharp growth in the types of technologies for which the IoT is already well-known including predictive maintenance in industry and automation at ports and other transportation facilities. In those areas IoT limits the amount of time workers spend on-site because remotely monitored systems don’t need to be maintained in-person nearly as often as they might otherwise. Some functions, including certain types of inspection and servicing, can be handled fully remotely, further reducing the amount of time workers have to spend on-site and in close proximity to one another.To read this article in full, please click here

Sacrificing Some Performance To Make Cloud Data Analytics Portable

The big three clouds – Amazon Web Services, Microsoft Azure, and Google Cloud – are all addressing the same issues of scale, performance, and economics and are also trying to attract the same workloads from the same pool of enterprise, government, and academic customers. …

6 East-West Security Myths Busted

With the world at our fingertips via a simple Google search, it can sometimes be tough to figure out what’s fact and what’s fiction. Whether you’re an expert, novice, or beginner in the tech world, time should be spent putting capabilities and terms into action – rather than trying to piece them together and understand them like a Sudoku puzzle. That’s why we’re going to debunk six major East-West security myths for you – so you can get back to the good stuff. 

1. East-West security is the monitoring and inspection of traffic moving medially within the network perimeter, working to identify and block threats and enable access rights.

Busted. East-West security does all of the fancy stuff mentioned, with one very important difference: it moves laterally through the network perimeter. This is a key understanding, since East-West security operates on the premise that threat factors will eventually find a way through next-generation firewalls – which means all internal network traffic is vulnerable.

2. A traditional firewall that manages North-South traffic can handle a modern network breach by itself. 

Busted. While it’s important to have North-South security in place (filtering the traffic that is exiting and entering the network), it cannot protect the network on its own Continue reading

Day Two Cloud 129: Practical Advice On Optimizing Cloud Costs

Optimizing cloud costs means more than looking at your bill and hunting down unused instances. It's about understanding the full lifecycle of cloud workloads, dealing with management that wants predictable spending even as your actual usage varies, and setting up repeatable processes. Guests Fred Chagnon and Jeremy Roberts, both at Info-Tech Research Group, offer practical advice for optimizing your cloud spending.

Catch 2022: Networking Ice Bucket Challenge

A sample topology

At the start of this exciting new year of 2022, I figured this might be a good time to introduce a new challenge:

Using Netsim-Tools, build the most complicated virtual network topology that still allows host A to ping host B

Anything goes — and if you have to extend the tooling to make things work, even better. Varying latency and occasional packet loss are acceptable, but there needs to be at least 1 ping reply being delivered to A.

For example, how about multi-vendor EVPN-VXLAN over SRv6 with MACsec encryption and Traffic Engineering?

Happy 2022 networking everyone! 🎆

Solo.io Brings ‘Docker-Like Experience’ to eBPF with BumbleBee

Service mesh integration software provider BumbleBee, a new open source project that it extended Berkeley Packet Filter (eBPF) in order to “shortcut the HTTP stack,” said Solo.io CEO and founder BPF Type Format (BTF), explained Levine, “(along with some smarts added to clang) enables the BPF program loader to fix the BPF byte code to work correctly on different versions of the kernel. For example, if a BPF program accesses a struct, clang now stores all these struct access in a special location in the BPF program binary. libbpf can go to each of these struct accesses, and use BTF information from the current kernel (obtained at runtime) to fix these accesses to the correct offset.” BumbleBee to the Rescue With the addition of BTF, Solo.io created BumbleBee, which not only uses BTF to parse and bring to the user space the maps of eBPF programs, but also uses the get started.
