Broadband RF scanner

One great thing about software defined radio is that you can become less blind to the invisible world of radio waves that’s all around us. One simple thing is to do a survey of the spectrum, to see what parts are busy.

More practically you can also use this to find which Wifi channels are least busy, so that you can get optimal performance on your network. Counting the number of networks is not a good indicator, since one network may be completely unused, while another is used 24/7 to stream Netflix. And some networks are hidden anyway, making them no more secure, but more annoying.

[GNU Radio][gnuradio] has a bunch of building blocks for some interactive peeking at spectrums, but there’s still some assembly required in order to make actually useful things.

To do a survey I used a USRP B200 with a [broadband spiral antenna. If you’re only interested in the Wifi spectrum then a 2.4/5GHz antenna is a better choice.

You can probably use a cheaper SDR, but you need to make sure it sends frequency tag updates in GNU Radio, so the block knows which frequency is tuned, as it moves across the spectrum.

Day Two Cloud 029: Kubernetes Needs To Disappear

This is a special holiday episode of Day Two Cloud with guest Kelsey Hightower, a Kubernetes evangelist and contributor. We discuss the current state of Kubernetes and the future for this orchestration platform, including how it will address networking, should you get certified, and will Kubernetes eventually fade into the background as hidden infrastructure you don't have to think about so much.

This holiday’s biggest online shopping day was… Black Friday

What’s the biggest day of the holiday season for holiday shopping? Black Friday, the day after US Thanksgiving, has been embraced globally as the day retail stores announce their sales. But it was believed that the following Monday, dubbed “Cyber Monday,” may be even bigger. Or, with the explosion of reliable 2-day and even 1-day shipping, maybe another day closer to Christmas has taken the crown. At Cloudflare, we aimed to answer this question for the 2019 holiday shopping season.

Black Friday was the biggest online shopping day but the second biggest wasn't Cyber Monday... it was Thanksgiving Day itself (the day before Black Friday!). Cyber Monday was the fourth biggest day.

Here's a look at checkout events seen across Cloudflare's network since before Thanksgiving in the US.

The weekends are shown in yellow and Black Friday and Cyber Monday are shown in green. You can see that checkouts ramped up during Thanksgiving week and then continued through the weekend into Cyber Monday.

Black Friday had twice the number of checkouts as the preceding Friday and the entire Thanksgiving week dominates. Post-Cyber Monday, no day reached 50% of the Continue reading

Lessons Learned from the Multistakeholder Process in the Philippines

In 2018, we began collaborating with the Philippines’ Department of Information and Communications Technology (DICT) to develop the country’s National ICT Ecosystem Framework (NICTEF), a successor to the Philippine Digital Strategy for 2011-2016.

The DICT, like all Philippine government agencies, is mandated by law to hold open consultations as a means of improving transparency and encouraging public involvement in the policymaking process. But it took this initiative further by ensuring that NICTEF is fully reflective of the needs and priorities of different sectors across the archipelago. For one year, the DICT led capacity building workshops, focus group discussions, writeshops, an online public survey, and regional consultations in each of the country’s major island groups, localizing the multistakeholder approach in the process to reach important and difficult decisions.

The NICTEF is now an authoritative guide on the Philippines’ digital ecosystem, and a roadmap to harmonize and coordinate the country’s ICT programs. The multistakeholder process adopted by NICTEF has been documented in a case study, offering other countries in the region a reference in developing public policies that are forward-thinking, inclusive, and suited to the needs of a steadily-interconnected world.

Below are some of our key takeaways from the process:

Unix is turning 50. What does that mean?

2020 is a significant year for Unix. At the very start of the year, Unix turns 50.While some of the early development of Unix predates the official start of its "epoch," Jan 1, 1970 remains the zero-point in POSIX time and the recognized beginning of all things Unix. Jan 1, 2020 will mark 50 years since that moment.Unix time vs human time In terms of human time, 50 years is a big deal. In terms of Unix time, there's nothing particularly special about 50 years. 48.7 years would be no less significant.Unix (including Linux) systems store date/time values as the number of seconds that have elapsed since 1970-01-01 00:00:00 UTC in 32 bits. To determine how many seconds have passed since that time and, thus, what right now looks like as a Unix time value, you can issue a command like this:To read this article in full, please click here

The Bookshelf

I am a big fan of Audible for books. Every once in a while I have time and patience to read a physical book, but often times I find myself needing to do things like washing dishes, going on a long walk or drive, and Audible has made it so much easier for me to get back into “reading”. Since I started doing this, I’d like to share the books that I’ve been able to get through this way.

About Matt

My name is Matt Oswalt, and I have a fairly eclectic background. When I was 14, I created my first program - an alien shooter on my TI-82 calculator. Since then, I’ve enjoyed building new things and showing them to anyone who will listen. This passion continues to this day, as you’ll find with projects like ToDD and NRE Labs, I just really enjoy building cool stuff. You can explore these and all my other open source projects on my GitHub profile.

DC. Part 16. Microsoft Azure SONiC on the Mellanox switches in data centre (with Cisco XR an Nokia SR OS for inter-OP).

Hello my friend,

The Christmas and New Year is coming, so it is typically the time to think about the future and plan ahead. And today we look into future by reviewing the new network operation system deployed in the data centres hosting Microsoft Azure clouds. This operation system is called SONiC: Software for Open Networking in the Cloud.

Recent VPN hacks reveal transparency issues within the industry and its supply chain

Consumers are no doubt becoming increasingly aware about the safety and security of their online activity after many highly publicized studies have shown an uptick in online data theft. According to the Federal Trade Commission, there were 3 million reports of identity theft alone in 2018.Even though these threats — and the rash of data breaches — continue to grab headlines, consumers still are connecting to public wifi despite the threats and are joining other unsafe networks while traveling. More cautious or tech-savvy individuals know to turn to virtual private networks (VPNs) as a way to safely connect online, and as VPNs become more mainstream, some project the VPN market can grow to more than $35 billion by 2022. We’ve even seen some vendors to capitalize by creating flashy TV commercials that insinuate that they are consumers’ digital doorman. To read this article in full, please click here
