Team collaboration has been an issue in the workplace for too long. Countless solutions have been proposed and tried. And here is a new idea. Can video game systems like PS5 be used for workplace team collaboration? The simple answer is yes. But how?
Video game systems have long had the option for multiplayer games. These also allow numerous people around the world to connect, create teams, and play against other teams. If you’re a true gamer, you would know how this works. However, what does this mean for offices? Video game systems like the PS5 have many features that can enable workplace team collaboration. Here are some of the ways this is encouraged.

Playing as a team in a video game would not only Continue reading
Cloudflare’s Always Online and the Internet Archive Team Up to Fight Origin Errors
Every day, all across the Internet, something bad but entirely normal happens: thousands of origin servers go down, resulting in connection errors and frustrated users. Cloudflare’s users collectively spend over four and a half years each day waiting for unreachable origin servers to respond with error messages. But visitors don’t want to see error pages, they want to see content!
Today is exciting for all those who want the Internet to be stronger, more resilient, and have important redundancies: Cloudflare is pleased to announce a partnership with the Internet Archive to bring new functionality to our Always Online service.
Always Online serves as insurance for our customers’ websites. Should a customer’s origin go offline, timeout, or otherwise break, Always Online is there to step in and serve archived copies of webpages to visitors. The Internet Archive is a nonprofit organization that runs the Wayback Machine, a service which saves snapshots of billions of websites across the Internet. By partnering with the Internet Archive, Cloudflare is able to seamlessly deliver responses for unreachable websites from the Internet Archive, while the Internet Archive can continue their mission of archiving the web to provide access to all knowledge.

Are Business Needs Just Excuses for Vendor Shenanigans?
Every now and then I call someone’s baby ugly (or maybe it was their third cousin’s baby and they nonetheless feel offended). In such cases a common resort is to cite business or market needs to prove how ignorant and clueless I am. Here’s a sample LinkedIn comment talking about my ignorance about the need for smart NICs:
The rise of custom silicon by Presando [sic], Mellanox, Amazon, Intel and others confirms there is a real market need.
Now let’s get something straight: while there are good reasons to use tons of different things that might look inappropriate, irrelevant or plain stupid to an outsider, I don’t believe in real market need argument being used to justify anything without supporting technical facts (tell me why you need that stuff and prove to me that using it is the best way of solving a problem).
Use Python to translate TCP/UDP port numbers to names
This short post shows how you can use Python to convert TCP/UDP port number to port name and vice versa.
Most of us know names of common TCP and UDP ports like 22/ssh, 23/telnet, 80/http or 443/https. We learn these early in our networking careers and many of them are so common that even when woken up middle of the night you'd know 53 is domain aka dns!
But there are also many not-so commonly used ports that have been given names. These ones sometimes show up in firewall logs or are mentioned in literature. Some vendors also try to replace numeric value with a human readable name in the configs and outputs of different commands.
One way or the other, I'd be good to have an easy method of getting port number given its name, and on occasion we might want to get name of particular port number.
There are many ways one could achieve that. We might search web, drop into documentation, or even check /etc/services if we have access to Linux box.
I decided to check if we can do some programmatic translation with Python, seeing as sometimes we could have hundreds of entries to process and Continue reading

New Grants Program for Researchers Studying the Future of the Internet
From the environment to the economy, the Internet is reshaping and disrupting several sectors of our society. What might future patterns of disruption look like? How will these changes affect all of us, particularly those on the margins of society? What new solutions can we generate today, to address the challenges of tomorrow?
At the Internet Society Foundation, we believe the answers to these questions and many others lies in research. That’s why we’re thrilled to announce a new grants program supporting researchers worldwide who are studying the future and sustainability of the Internet. Grants of up to US$200,000 are available for research lasting up to two years and focused in one of two categories:
- Greening the Internet: How the Internet affects and is affected by the environment
- The Internet Economy: How digital technologies are transforming our economic landscape
Established in 2019 to support the positive difference the Internet can make to people everywhere, the Internet Society Foundation awards grants to Internet Society Chapters/Special Interest Groups (SIGs) as well as nonprofit organizations and individuals dedicated to providing meaningful access to an open, globally-connected, secure, and trustworthy Internet for everyone.

Moobot vs. Gatebot: Cloudflare Automatically Blocks Botnet DDoS Attack Topping At 654 Gbps
On July 3, Cloudflare’s global DDoS protection system, Gatebot, automatically detected and mitigated a UDP-based DDoS attack that peaked at 654 Gbps. The attack was part of a ten-day multi-vector DDoS campaign targeting a Magic Transit customer and was mitigated without any human intervention. The DDoS campaign is believed to have been generated by Moobot, a Mirai-based botnet. No downtime, service degradation, or false positives were reported by the customer.
Over those ten days, our systems automatically detected and mitigated over 5,000 DDoS attacks against this one customer, mainly UDP floods, SYN floods, ACK floods, and GRE floods. The largest DDoS attack was a UDP flood and lasted a mere 2 minutes. This attack targeted only one IP address but hit multiple ports. The attack originated from 18,705 unique IP addresses, each believed to be a Moobot-infected IoT device.
The attack was observed in Cloudflare’s data centers in 100 countries around the world. Approximately 89% of the attack traffic originated from just 10 countries with the US leading at 41%, followed by South Korea and Japan in second place (12% each), Continue reading
Restoring data to Netbox Docker
