The Week in Internet News: U.S. Lawmakers Skewer Big Tech Firms

Attacking the big guys: During an antitrust hearing, U.S. lawmakers – both Democrats and Republicans – heaped criticism on Amazon, Apple, Facebook, and Google about their market power, the Washington Post reports. “Our founders would not bow before a king. Nor should we bow before the emperors of the online economy,” said Representative David Cicilline, a Rhode Island Democrat. Republicans complained about alleged anti-conservative bias in online services, while many Democrats talked about how the companies’ market power was being used against competitors, NPR says.

Encryption laws vs. the economy: Laws in Australia creating law enforcement access to encrypted communications are hurting the tech sector in the country, tech giant Atlassian told lawmakers there, the Guardian reports. The anti-encryption laws have discouraged talent from working in Australia and may limit economic growth during the post-COVID-19 recovery, the company said.

Paying for news: Also in Australia, the government there has released the world’s first draft law to force Google and Facebook to pay traditional news media to publish their material, Al Jazeera reports. Under the plan, the tech companies would have to negotiate with Australian media companies to use their content.

MUST READ: SR(x)6 – Snake Oil Or Salvation?

I wanted to write a “SRv6 makes no little sense” blog post for a long while, but there were always more relevant topics to focus on. Fortunately I won’t have to write it anytime soon; Ethan Banks did a fantastic job with SR(x)6 - Snake Oil Or Salvation?. Make sure you read it before attending the next “SRx6 will save the world” vendor presentation.

Nutrition Innovations You Shouldn’t Miss

With the passage of time, the entire world continues to change – bringing about different innovations that were previously never known to humans. These innovations arise in various fields and are extremely noteworthy, because not only do they contain benefits, but they are also extremely convenient as compared to older measures.

Similar is the case for nutrition. Previously, to gain different health benefits and strength in various areas, one would have to combine a number of different fruits, vegetables, or any type of food and combine them together to get some form of nutrients for the body. However, these ways would consume an immense amount of time.

There is no doubt that in today’s world, the only thing everyone is short on is time. For this reason, some natural health brands are known for bringing about various nutrition innovations over the years, which can boost your health to a great extent.

These are the latest innovations, which you need to incorporate into your lifestyle so that you can feel more energized and healthier, each step of the way!

Improve Your Sleep Cycle

One of the greatest fight’s humans have with themselves is with their inner need for sleep. The time Continue reading

Transferring pictures with DStar

I’ve successfully experimented with sending pictures using the data portion of D-Star.

I did it in multiple ways, starting with the simplest and ending with the longest path (though not most complex).

Equipment is an Android phone, a Kenwood TH-D74, and an ICom IC-9700.

Simplex

First I did it the simplest way, using simplex between the radios.

You install the ICom RS-MS1A app (sigh, yes that’s the kind of useful naming scheme they have). You’d think this app is needed for the ICom radio, but no. The IC-9700 has Picture mode built in. I used this app for the Kenwood D74.

You start the app, select “Others (Bluetooth)”, and select the D74.

On the D74 you need to:

1. Press 1 to go into VFO mode
2. Select the right frequency
3. Set the mode to digital (DV/DR)
4. If it’s DR, switch it to DV in the digital menu.
5. In the digital menu, switch it to DATA

Annoyingly, unlike the native picture mode in the IC9700, setting DATA mode on the D74 will not allow any voice transmission at all.

On the IC9700, just set the right frequency, switch to DV mode, and select Picture from the menu.

I won’t go into detail Continue reading

Commit to Diversity, Equity and Inclusion, Every Day

The world is waking up
Protesting in the name of Black Lives Matter.
Reading the book “White Fragility”.
Watching the documentary “13th”.

The world is waking up to the fight against racism and I couldn’t be happier!

But let’s be clear: learning about anti-racism and being anti-racist are not the same things. Learning is a good first step and a necessary one. But if you don’t apply the knowledge you acquire, then you are not helping to move the needle.

Since the murder of George Floyd at the hands/knees of the Minneapolis police, people all over the world have been focused on Black Lives Matter and anti-racism. At Cloudflare, we’ve seen an increase in cyberattacks, we’ve heard from the leadership of Afroflare, our Employee Resource Group for employees of African descent, and we held our first ever Day On, held on June 18, Cloudflare’s employee day of learning about bias, the history and psychological effects of racism,, and how racism can get baked into algorithms.

By way of this blog post, I want to share my thoughts about where I think we go from here and how I believe we can truly embody Diversity Equity and Inclusion (DEI) Continue reading

Tribal Priority Window extended to September 2 – but it’s still not enough time to connect Indigenous communities to a critical lifeline

While Indigenous communities across the US battle some of the most brutal COVID-19 mortality rates in the country, they’ve simultaneously raced against the clock to take advantage of a once-in-a-generation opportunity to access and manage their own broadband.

The Tribal Priority Window is an unprecedented opportunity for eligible US Tribes to apply for 2.5GHz spectrum leases ahead of the federal auction. Targeted at the most digitally underserved communities in the US— where only half of housing units have access to broadband— the Window is intended to enable rural Tribes access to Internet service and the development of services to narrow the digital divide. The application process posed significant challenges to Tribes who already struggle with poor connectivity. The digital format, coupled with COVID-19 realities, has hampered their ability to file applications within the deadline.

Due to the insurmountable obstacles posed by the pandemic, Tribes and nearly 100 organizations have called on the Federal Communications Commission (FCC) and Congress to extend the Tribal Priority Window by 180 days.

In response, the FCC has granted them just 30 additional days to file their applications. In its order, the FCC says that this extension is due to the unusual Continue reading

Fast Friday – Mobility Field Day 5 Edition

I’ve been in the middle of Mobility Field Day 5 this week with a great group of friends and presenters. There’s a lot to unpack. I wanted to share some quick thoughts around wireless technologies and where we’re headed with it.

• Wireless isn’t magic. We know that because it’s damned hard to build a deployment plan and figure out where to put APs. We’ve built tools that help us immensely. We’ve worked on a variety of great things that enable us to make it happen easier than it’s been before. But remember that the work still has to happen and we still have to understand it. As soon as someone says, “You don’t need to do the work, our tool just makes it happen” my defenses go up. How does the tool understand nuance? Who is double-checking it? What happens when you can’t feed it all the info it needs? Don’t assume that taking a human out of the loop is always good thing. Accrued knowledge is more important than you realize.
• Analytics give you a good picture of what you want, but they don’t turn wrenches. All the data in the world won’t replace a keyboard. You need to Continue reading

The HashiCorp Consul Service Comes to Microsoft Azure

The release of HashiCorp’s push to widen the scope of its managed services offerings on the cloud. The GA release of HCS on Armon Dadgar, co-founder and CTO of HashiCorp, said the Azure HCS release is part of HashiCorp’s shift to a more managed-services business model. “We are transitioning from being a desktop software vendor to becoming more of a cloud software vendor,” said Dadgar. Dadgar said HashiCorp opted for Azure since there is a lot of overlap between the kinds of customer organizations HashiCorp and Microsoft tend to focus on. The launch Continue reading

Weekend Reads 073120

More than 4.7 million sources in five countries — the US, China, South Korea, Russia, and India — were used to level distributed denial-of-service (DDoS) attacks against victims in the second quarter of 2020, with the portmap protocol most frequently used as an amplification vector to create massive data floods, security and services firm A10 Networks says in its threat report for the second quarter.

Thousands of people graduate from colleges and universities each year with cybersecurity or computer science degrees only to find employers are less than thrilled about their hands-on, foundational skills. Here’s a look at a recent survey that identified some of the bigger skills gaps, and some thoughts about how those seeking a career in these fields can better stand out from the crowd.

Three standards for email security that are supposed to verify the source of a message have critical implementation differences that could allow attackers to send emails from one domain and have them verified as sent from a different — more legitimate-seeming — domain, says a research team who will present their findings at the virtual Black Hat conference next month.

Member News: Teaching Computer Science in Rural Nigeria

Computing for the people: The San Francisco Chapter has an article by a software developer using open source software and open standards hardware to teach computer science skills to students in rural Nigeria. Chioma Ezedi Chukwu, founder of the STEMTeers mentorship program, writes that open source is more than free tools, software, or hardware. “It was a great opportunity to learn, learn by building and create with innovation.”

Coding for kids: Meanwhile, the Pacific Islands Chapter highlights a hackathon for kids event at a childcare center in Port Moresby, Papua New Guinea. The goal of the event, focused on design thinking, was to equip the students with lifelong skills in the digital age.

Supporting e-learning: In other education-related news, the Uganda Chapter is focused on helping teachers and students improve their digital skills as the country embraces e-learning following the COVID-19 pandemic. “Educators need to adjust their teaching methods to cope with the new changes,” an article says. “Educators should be able to cause change or affect the learner beyond the chalk and blackboard while learners need to be taken through an adaptability process as they transition to digital education.”

Making magic: Reimagining Developer Experience for the World of Serverless

This week we’ve talked about how Workers provides a step function improvement in the TTFB (time to first byte) of applications, by running lightweight isolates in over 200 cities around the world, free of cold starts. Today I’m going to talk about another metric, one that’s arguably even more important: TTFD, or time to first dopamine, and announce a huge improvement to the Workers development experience — wrangler dev, our edge-based development environment with all the perks of a local environment.

There’s nothing quite like the rush of getting your first few lines of code to work — no matter how many times you’ve done it before, there's something so magical about the computer understanding exactly what you wanted it to do and doing it!

This is the kind of magic I expected of “serverless”, and while it’s true that most serverless offerings today get you to that feeling faster than setting up a virtual server ever would, I still can’t help but be disappointed with how lackluster developing with most serverless platforms is today.

Some of my disappointment can be attributed to the leaky nature of the abstraction: the journey to getting you to the point of writing Continue reading

Worth Reading: How CEOs think

Robert Graham wrote a great article explaining why CEOs don’t care much about cybersecurity or any other non-core infrastructure (including networking, unless you happen to be working for a service provider). It’s a must-read if you want to understand the **** you have to deal with in enterprise environments.
