Data@Mozilla: This Week in Glean: Glean & GeckoView

14 hours 4 min ago

(“This Week in Glean” is a series of blog posts that the Glean Team at Mozilla is using to try to communicate better about our work. They could be release notes, documentation, hopes, dreams, or whatever: so long as it is inspired by Glean.) All “This Week in Glean” blog posts are listed in the TWiG index.

This is a followup post to Shipping Glean with GeckoView.

It landed!

It took us several more weeks to put everything into place, but we’re finally shipping the Rust parts of the Glean Android SDK with GeckoView and consume that in Android Components and Fenix. And it still all works, collects data and is sending pings! Additionally this results in a slightly smaller APK as well.

This unblocks further work now. Currently Gecko simply stubs out all calls to Glean when compiled for Android, but we will enable recording Glean metrics within Gecko and exposing them in pings sent from Fenix. We will also start work on moving other Rust components into mozilla-central in order for them to use the Rust API of Glean directly. Changing how we deliver the Rust code also made testing Glean changes across these different components a bit more challenging, so I want to invest some time to make that easier again.

The Mozilla Blog: The Great Resignation: New gig? Here are 7 tips to ensure success

Thursday 16th of September 2021 08:20:00 PM

If recent surveys and polls ring true, over 46% of the global workforce is considering leaving their employer this year. Despite COVID-19 causing initial turnover due to the related economic downturn, the current phenomenon coined “The Great Resignation” is attributed to the many job seekers choosing to leave their current employment voluntarily. Mass vaccinations and mask mandates have allowed offices to re-open just as job seekers are reassessing work-life balance, making bold moves to take control of where they choose to live and work. 

The “New Normal”

Millions of workers have adjusted to remote-flexible work arrangements, finding success and a greater sense of work-life balance. The question is whether or not employers will permanently allow this benefit post-pandemic.

Jerry Lee, COO/Founder of the career development consultancy, Wonsulting, sees changes coming to the workplace power dynamic.

“In the future of work, employers will have to be much more employee-first beyond monetary compensation,” he said. “There is a shift of negotiating power moving from the employers to the employees, which calls for company benefits and work-life balance to improve.” 

Abbie Duckham, Talent Operations Program Manager at Mozilla, believes the days of companies choosing people are long over. 

“From a hiring lens, it’s no longer about companies choosing people, it’s about people choosing companies,” Duckham said. “People are choosing to work at companies that, yes, value productivity and revenue – but more-so companies that value mental health and understand that every single person on their staff has a different home life or work-life balance.”

Drop the mic and cue the job switch

So, how can recent job switchers or job seekers better prepare for their next big move? The following tips and advice from career and talent sourcing experts can help anyone perform their best while adapting to our current pandemic reality.

Take a vacation *seriously*

When starting a new role many are keen to jump into work right away; however, it’s always important to take a mental break between your different roles before you start another onboarding process,” advises Jonathan Javier, CEO/Founder at Wonsulting. “One way to do this is to plan your vacations ahead of your switch: that trip to Hawaii you always wanted? Plan it right after you end your job. That time you wanted to spend with your significant other? Enjoy that time off.” 

It also never hurts to negotiate a start date that does not prioritize your mental preparedness and well-being.

Out with the old and in with that new-new

When Duckham started at Mozilla, she made it her mission to absorb every bit of the manifesto to better understand Mozilla’s culture. “From there I looked into what we actually do as a company. Setting up a Firefox account was pretty crucial since we are all about dog-fooding here (or as we call it, foxfooding), and then downloading Firefox Nightly, the latest beta-snapshot of the browser as our developers are actively working on it.”

Duckham also implores job-switchers to rebrand themselves. 

“You have a chance to take everything you wanted your last company to know about you and restart,” she said. “Take everything you had imposter syndrome about and flip the switch.”

Network early

“When you join a new company, it’s important to identify the subject matter experts for different functions of your company so you know who you can reach out to if you have any questions or need insights,” Javier said.

Javier also recommends networking with people who have also switched jobs. 

“You can search for and find people who switched from non-tech roles to an in-tech role by simply searching for ‘Past Company’ at a non-tech company and then putting ‘Current Company’ at a tech company on LinkedIn,” he said.


Duckham went as far as giving her digital workspace a refreshing overhaul when she started at Mozilla. 

“I cleaned off my desktop, made folders for storing files, and essentially crafted a blank working space to start fresh from my previous company – effectively tabula rasa-ing my digital workspace did the same for my mental state as I prepared to absorb tons of new processes and practices.”

In that same vein, when you need a bit of a brain-break throughout the work day and that break leads you to social media, Duckham advises downloading Facebook Container, a browser extension that makes it harder for Facebook to track you on the web outside of Facebook.

“Speaking of brain-breaks, if socials aren’t your thing and you’d rather catch up on written curated content from around the web, Pocket is an excellent way to let your mind wander and breathe during the work day so you’re able return to work a little more refreshed,” Duckham added.

Making remote friends and drawing boundary lines

56% of Mozilla employees signed in to work from remote locations all over the world, even before the pandemic. Working asynchronously across so many time zones can be unusual for new teammates. Duckham’s biggest tip for new Mozillians? 

“Be open and a little vulnerable. Do you need to take your kid to school every day, does your dog require a mid-day walk? Chances are your schedule is just as unique as the person in the Zoom window next to you. Be open about the personal time you need to take throughout the day and then build your work schedule around it.” 

But what about building comradery and remote-friendships

“In a traditional work environment, you might run into your colleagues in the break room and have a quick chat. As roles continue to become more remote or hybrid-first, it is important to create opportunities for you to mingle with your colleagues,” Jerry Lee of Wonsulting said. “These small interactions are what builds long-lasting friendships, which in turn allows you to feel more comfortable and productive at work.”

How to leverage pay, flexibility and other benefits even if you aren’t job searching

“The best leverage you can find in this job market – is clearly defining what is important for you and making sure you have that option in your role,” Lee said. 

He’s not wrong. Make sure to consider your current growth opportunities, autonomy, location, work-life flexibility and compensation, of course. For example, if you are looking for a flexible-remote arrangement, Lee suggests clearly articulating what it is you want to your manager using the following talk-track as a guide:

Hey Manager!

I’m looking for ways to better incorporate my work into my personal life, and I’ve realized one important factor for me is location flexibility. I’m looking to move around a bit in the next few years but would love to continue the work I have here.

What can we do to make this happen?

Once you make your request, you’ll need to work with your manager to ensure your productivity and impact improves or at least remains the same.

Finally, it’s always helpful to remind yourself that every ‘big’ career move is the result of several smaller moves. If you’re looking to make a switch or simply reaccessing your current work-life balance, Javier recommends practicing vision boarding. “I do this by drawing my current state and what I want my future state to look like,” said Javier. “Even if your drawings are not subpar, you’ll be able to visualize what you want to accomplish in the future and make it into reality.”

As the Great Resignation continues, it is important to keep in mind that getting a new job is just the start of the journey. There are important steps that you can do, and Firefox and Pocket can help, to make sure that you feel ready for your next career adventure.

Niko Matsakis: Rustacean Principles, continued

Thursday 16th of September 2021 01:42:00 PM

RustConf is always a good time for reflecting on the project. For me, the last week has been particularly “reflective”. Since announcing the Rustacean Principles, I’ve been having a number of conversations with members of the community about how they can be improved. I wanted to write a post summarizing some of the feedback I’ve gotten.

The principles are a work-in-progress

Sparking conversation about the principles was exactly what I was hoping for when I posted the previous blog post. The principles have mostly been the product of Josh and I iterating, and hence reflect our experiences. While the two of us have been involved in quite a few parts of the project, for the document to truly serve its purpose, it needs input from the community as a whole.

Unfortunately, for many people, the way I presented the principles made it seem like I was trying to unveil a fait accompli, rather than seeking input on a work-in-progress. I hope this post makes the intention more clear!

The principles as a continuation of Rust’s traditions

Rust has a long tradition of articulating its values. This is why we have a Code of Conduct. This is why we wrote blog posts like Fearless Concurrency, Stability as a Deliverable and Rust Once, Run Anywhere. Looking past the “engineering side” of Rust, aturon’s classic blog posts on listening and trust (part 1, part 2, part 3) did a great job of talking about what it is like to be on a Rust team. And who could forget the whole “fireflowers” debate?1

My goal with the Rustacean Principles is to help coalesce the existing wisdom found in those classic Rust blog posts into a more concise form. To that end, I took initial inspiration from how AWS uses tenets, although by this point the principles have evolved into a somewhat different form. I like the way tenets use short, crisp statements that identify important concepts, and I like the way assigning a priority ordering helps establish which should have priority. (That said, one of Rust’s oldest values is synthesis: we try to find ways to resolve constraints that are in tension by having our cake and eating it too.)

Given all of this backdrop, I was pretty enthused by a suggestion that I heard from Jacob Finkelman. He suggested adapting the principles to incorporate more of the “classic Rust catchphrases”, such as the “no new rationale” rule described in the first blog post from aturon’s series. A similar idea is to incorporate the lessons from RFCs, both successful and unsuccessful (this is what I was going for in the case studies section, but that clearly needs to be expanded).

The overall goal: Empowerment

My original intention was to structure the principles as a cascading series of ideas:

  • Rust’s top-level goal: Empowerment
    • Principles: Dissecting empowerment into its constituent pieces – reliable, performant, etc – and analyzing the importance of those pieces relative to one another.
      • Mechanisms: Specific rules that we use, like type safety, that engender the principles (reliability, performance, etc.). These mechanisms often work in favor of one principle, but can work against others.

wycats suggested that the site could do a better job of clarifying that empowerment is the top-level, overriding goal, and I agree. I’m going to try and tweak the site to make it clearer.

A goal, not a minimum bar

The principles in “How to Rustacean” were meant to be aspirational: a target to be reaching for. We’re all human: nobody does everything right all the time. But, as Matklad describes, the principles could be understood as setting up a kind of minimum bar – to be a team member, one has to show up, follow through, trust and delegate, all while bringing joy? This could be really stressful for people.

The goal for the “How to Rustacean” section is to be a way to lift people up by giving them clear guidance for how to succeed; it helps us to answer people when they ask “what should I do to get onto the lang/compiler/whatever team”. The internals thread had a number of good ideas for how to help it serve this intended purpose without stressing people out, such as cuviper’s suggestion to use fictional characters like Ferris in examples, passcod’s suggestion of discussing inclusion, or Matklad’s proposal to add something to the effect of “You don’t have to be perfect” to the list. Iteration needed!

Scope of the principles

Some people have wondered why the principles are framed in a rather general way, one that applies to all of Rust, instead of being specific to the lang team. It’s a fair question! In fact, they didn’t start this way. They started their life as a rather narrow set of “design tenets for async” that appeared in the async vision doc. But as those evolved, I found that they were starting to sound like design goals for Rust as a whole, not specifically for async.

Trying to describe Rust as a “coherent whole” makes a lot of sense to me. After all, the experience of using Rust is shaped by all of its facets: the language, the libraries, the tooling, the community, even its internal infrastructure (which contributes to that feeling of reliability by ensuring that the releases are available and high quality). Every part has its own role to play, but they are all working towards the same goal of empowering Rust’s users.2

There is an interesting question about the long-term trajectory for this work. In my mind, the principles remain something of an experiment. Presuming that they prove to be useful, I think that they would make a nice RFC.

What about “easy”?

One final bit of feedback I heard from Carl Lerche is surprise that the principles don’t include the word “easy”. This not an accident. I felt that “easy to use” was too subjective to be actionable, and that the goals of productive and supportive were more precise. However, I do think that for people to feel empowered, it’s important for them not feel mentally overloaded, and Rust can definitely have the problem of carrying a high mental load sometimes.

I’m not sure the best way to tweak the “Rust empowers by being…” section to reflect this, but the answer may lie with the Cognitive Dimensions of Notation. I was introduced to these from Felienne Herman’s excellent book The Programmer’s Brain; I quite enjoyed this journal article as well.

The idea of the CDN is to try and elaborate on the ways that tools can be easier or harder to use for a particular task. For example, Rust would likely do well on the “error prone” dimension, in that when you make changes, the compiler generally helps ensure they are correct. But Rust does tend to have a high “viscosity”, because making local changes tends to be difficult: adding a lifetime, for example, can require updating data structures all over the code in an annoying cascade.

It’s important though to keep in mind that the CDN will vary from task to task. There are many kinds of changes one can make in Rust with very low viscosity, such as adding a new dependency. On the other hand, there are also cases where Rust can be error prone, such as mixing async runtimes.


In retrospect, I wish I had introduced the concept of the Rustacean Principles in a different way. But the subsequent conversations have been really great, and I’m pretty excited by all the ideas on how to improve them. I want to encourage folks again to come over to the internals thread with their thoughts and suggestions.

  1. Love that web page, brson

  2. One interesting question: I do think that some tools may vary the prioritization of different aspects of Rust. For example, a tool for formal verification is obviously aimed at users that particularly value reliability, but other tools may have different audiences. I’m not sure yet the best way to capture that, it may well be that each tool can have its own take on the way that it particularly empowers. 

The Mozilla Blog: Mozilla VPN adds advanced privacy features: Custom DNS servers and Multi-hop

Wednesday 15th of September 2021 10:43:21 PM

Your online privacy remains our top priority, and we know that one of the first things to secure your privacy when you go online is to get on a Virtual Private Network (VPN), an encrypted connection that serves as a tunnel between your computer and VPN server. Today, we’re launching the latest release of our Mozilla VPN, our fast and easy-to-use VPN service, with two new advanced privacy features that offer additional layers of privacy. This includes your choice of Domain Name System (DNS) servers whether it’s the default we’ve provided, our suggested ad blocking, tracker blocking or ad plus tracker blocking DNS server, or an alternative one, plus the multi-hop feature which allows you to add two different servers to give you twice the amount of encryption. Today’s Mozilla VPN release is available on Windows, Mac, Linux and Android platforms (it will soon be available on iOS later this week).

Here are today’s Mozilla VPN Features: Uplevel your privacy with Mozilla VPN’s Custom DNS server feature

Traditionally when you go online your traffic is routed through your Internet Service Provider’s (ISP) DNS servers who may be keeping records of your online activities. DNS, which stands for Domain Name System, is like a phone book for domains, which are the websites that you visit. One of the advantages to using a VPN is shielding your online activity from your ISP by using your trusted VPN service provider’s DNS servers. There are a variety of DNS servers, from ones that offer additional features like tracker blocking, ad blocking or a combination of both tracker and ad blocking, or local DNS servers that have those benefits along with speed. 

Now, with today’s Custom DNS server, we put you in control of choosing your DNS server that fits your needs. You can find this feature in your Network Settings under Advanced DNS Settings. From there, you can choose from the default DNS server, enter your local DNS server, or choose from the recommended list of DNS servers available to you. 

<figcaption>Choose from the recommended list of DNS servers available to you</figcaption> Double up your VPN service with Mozilla’s VPN Multi-hop feature

We’re introducing our Multi-hop feature which is also known as doubling up your VPN because instead of using one VPN server you can use two VPN servers. Here’s how it works, first your online activity is routed through one VPN server. Then, by selecting the Multi-Hop feature, your online activity will get routed a second time through an extra VPN server which is known as your exit server. Essentially, you will have two VPN servers which are known as the entry VPN server and exit VPN server. This new powerful privacy feature appeals to those who think twice about their privacy, like political activists, journalists writing sensitive topics, or anyone who’s using a public wi-fi and wants that added peace of mind by doubling-up their VPN servers.

To turn on this new feature, go to your Location, then choose Multi-hop. From there, you can choose your entry server location and your exit server location. The exit server location will be your main VPN server. We will also list your two recent Multi-hop connections so you can reuse them in the future. 

<figcaption>Choose your entry server location and your exit server location</figcaption> <figcaption>Your two recent Multi-hop connections will also be listed and available to reuse in the future</figcaption> How we innovate and build features for you with Mozilla VPN

Developed by Mozilla, a mission-driven company with a 20-year track record of fighting for online privacy and a healthier internet, we are committed to innovate and bring new features to the Mozilla VPN. Mozilla periodically works with third-party organizations to complement our internal security programs and help improve the overall security of our products. Mozilla recently published an independent security audit of its Mozilla VPN from Cure53, an unbiased cybersecurity firm based in Berlin with more than 15 years of running software testing and code auditing. Here is a link to the blog post and the security audit for more details. 

We know that it’s more important than ever for you to be safe, and for you to know that what you do online is your own business. By subscribing to Mozilla VPN, users support both Mozilla’s product development and our mission to build a better web for all. Check out the Mozilla VPN and subscribe today from our website.

The Mozilla Blog: Get where you’re going faster, with Firefox Suggest

Wednesday 15th of September 2021 04:16:30 PM

Today, people have to work too hard to find what they want online, sifting through and steering clear of content, clutter and click-bait not worthy of their time. Over time, navigation on the internet has become increasingly centralized and optimized for clicks and scrolling, not for getting people to where they want to go or what they are looking for quickly. 

We’d like to help change this, and we think Firefox is a good place to start.

Today we’re announcing our first step towards doing that with a new feature called Firefox Suggest.

Firefox Suggest is a new discovery feature that is built directly into the browser. Firefox Suggest acts as a trustworthy guide to the better web, surfacing relevant information and sites to help people accomplish their goals. Check it out here:

Relevant, reliable answers: 

Firefox already helps people search their browsing history and tabs and use their preferred search engine directly from Firefox’s Awesome Bar. 

Firefox Suggest will enhance this by including other sources of information such as Wikipedia, Pocket articles, reviews and credible content from sponsored, vetted partners and trusted organizations. 

For instance, suppose someone types “Costa Rica” into the Awesome Bar, they might see a result from Wikipedia:

<figcaption>Firefox users can find suggestions from Wikipedia</figcaption>

Firefox Suggest also contains sponsored suggestions from vetted partners. For instance, if someone types in “vans”, we might show a sponsored result for Vans shoes on eBay:

<figcaption>Firefox users can find sponsored suggestions from vetted partners</figcaption>

We are also developing contextual suggestions. These aim to enhance and speed up your searching experience. To deliver contextual suggestions, Firefox will need to send Mozilla new data, specifically, what you type into the search bar, city-level location data to know what’s nearby and relevant, as well as whether you click on a suggestion and which suggestion you click on.

In your control:

As always, we believe people should be in control of their web experience, so Firefox Suggest will be a customizable feature. 

We’ll begin offering contextual suggestions to a percentage of people in the U.S. as an opt-in experience. 

<figcaption>Opt-in prompt for smarter, contextual suggestions</figcaption>

Find out more about the ways you can customize this experience here.

Unmatched privacy: 

We believe online ads can work without advertisers needing to know everything about you. So when people choose to enable smarter suggestions, we will collect only the data that we need to operate, update and improve the functionality of Firefox Suggest and the overall user experience based on our Lean Data and Data Privacy Principles. We will also continue to be transparent about our data and data collection practices as we develop this new feature.

A better web. 

The internet has so much to offer, and we want to help people get the best out of it faster and easier than ever before.

Firefox is the choice for people who want to experience the web as a purpose driven and independent company envisions it. We create software for people that provides real privacy, transparency and valuable help with navigating today’s internet. This is another step in our journey to build a better internet.

Niko Matsakis: CTCFT 2021-09-20 Agenda

Wednesday 15th of September 2021 01:45:00 PM

The next “Cross Team Collaboration Fun Times” (CTCFT) meeting will take place next Monday, on 2021-09-20 (in your time zone)! This post covers the agenda. You’ll find the full details (along with a calendar event, zoom details, etc) on the CTCFT website.

  • Announcements
  • Interest group panel discussion

We’re going to try something a bit different this time! The agenda is going to focus on Rust interest groups and domain working groups, those brave explorers who are trying to put Rust to use on all kinds of interesting domains. Rather than having fixed presentations, we’re going to have a panel discussion with representatives from a number of Rust interest groups and domain groups, led by AngelOnFira. The idea is to open a channel for communication about how to have more active communication and feedback between interest groups and the Rust teams (in both directions).

Afterwards: Social hour

After the CTCFT this week, we are going to try an experimental social hour. The hour will be coordinated in the #ctcft stream of the rust-lang Zulip. The idea is to create breakout rooms where people can gather to talk, hack together, or just chill.

Data@Mozilla: Data and Firefox Suggest

Wednesday 15th of September 2021 09:00:41 AM

Firefox Suggest is a new feature that displays direct links to content on the web based on what users type into the Firefox address bar. Some of the content that appears in these suggestions is provided by partners, and some of the content is sponsored.

In building Firefox Suggest, we have followed our long-standing Lean Data Practices and Data Privacy Principles. Practically, this means that we take care to limit what we collect, and to limit what we pass on to our partners. The behavior of the feature is straightforward–suggestions are shown as you type, and are directly relevant to what you type.

We take the security of the datasets needed to provide this feature very seriously. We pursue multi-layered security controls and practices, and strive to make as much of our work as possible publicly verifiable.

In this post, we wanted to give more detail about what data is needed to provide this feature, and about how we handle it.

Changes with Firefox Suggest

The address bar experience in Firefox has long been a blend of results provided by partners (such as the user’s default search provider) and information local to the client (such as recently visited pages). For the first time, Firefox Suggest augments these data sources with search completions from Mozilla.

In its current form, Firefox Suggest compares searches against a list of allowed terms that is local to the client. When the search text matches a term on the allowed list, a completion suggestion may be shown alongside the local and default search engine suggestions.

Data Collected by Mozilla

Mozilla collects the following information to power Firefox Suggest when users have opted in to contextual suggestions.

  • Search queries and suggest impressions: Firefox Suggest sends Mozilla search terms and information about engagement with Firefox Suggest, some of which may be shared with partners to provide and improve the suggested content.
  • Clicks on suggestions: When a user clicks on a suggestion, Mozilla receives notice that suggested links were clicked.
  • Location: Mozilla collects city-level location data along with searches, in order to properly serve location-sensitive queries.
How Data is Handled and Shared

Mozilla approaches handling this data conservatively. We take care to remove data from our systems as soon as it’s no longer needed. When passing data on to our partners, we are careful to only provide the partner with the minimum information required to serve the feature.

A specific example of this principle in action is the search’s location. The location of a search is derived from the Firefox client’s IP address. However, the IP address can identify a person far more precisely than is necessary for our purposes. We therefore convert the IP address to a more general location immediately after we receive it, and we remove the IP address from all datasets and reports downstream. Access to machines and (temporary, short-lived) datasets that might include the IP address is highly restricted, and limited only to a small number of administrators. We don’t enable or allow analysis on data that includes IP addresses.

We’re excited to be bringing Firefox Suggest to you. See the product announcement to learn more!

The Talospace Project: Firefox 92 on POWER

Tuesday 14th of September 2021 02:31:17 AM
Firefox 92 is out. Alongside some solid DOM and CSS improvements, the most interesting bug fix I noticed was a patch for open alerts slowing down other tabs in the same process. In the absence of a JIT we rely heavily on Firefox's multiprocessor capabilities to make the most of our multicore beasts, and this apparently benefits (among others, but in particular) the Google sites we unfortunately have to use in these less-free times. I should note for the record that on this dual-8 Talos II (64 hardware threads) I have dom.ipc.processCount modestly increased to 12 from the default of 8 to take a little more advantage of the system when idle, which also takes down fewer tabs in the rare cases when a content process bombs out. The delay in posting this was waiting for the firefox-appmenu patches, but I decided to just build it now and add those in later. The .mozconfigs and LTO-PGO patches are unchanged from Firefox 90/91.

Meanwhile, in OpenPOWER JIT progress, I'm about halfway through getting the Wasm tests to pass, though I'm currently hung up on a memory corruption bug while testing Wasm garbage collection. It's our bug; it doesn't happen with the C++ interpreter, but unfortunately like most GC bugs it requires hitting it "just right" to find the faulty code. When it all passes, we'll pull everything up to 91ESR for the MVP, and you can try building it. If you want this to happen faster, please pitch in and help.

The Mozilla Blog: Matrix 4, Blue’s Clues, #StarTrekDay and More — Everything That’s Old is New Again in This Week’s Top Shelf

Friday 10th of September 2021 09:29:55 PM

At Mozilla, we believe part of making the internet we want is celebrating the best of the internet, and that can be as simple as sharing a tweet that made us pause in our feed. Twitter isn’t perfect, but there are individual tweets that come pretty close.

Each week in Top Shelf, we will be sharing the tweets that made us laugh, think, Pocket them for later, text our friends, and want to continue the internet revolution each week.

Here’s what made it to the Top Shelf for the week of September 6, 2021, in no particular order.

{Nostalgia has entered the chat} This week saw people online reacting to pop-culture references that are making a comeback. As one person put it: “It’s the 90s again, baby!” And while 1990 was NOT, in fact, 10 years ago, it looks like our childhood is back in full force!

The Mozilla Blog: Did internet friends fill the gaps left by social distance?

Thursday 9th of September 2021 02:35:00 PM

March 2020 brought to the world a scenario we only imagined possible in dystopian novels. Once bustling cities and towns were desolate. In contrast, the highways and byways of the internet were completely congested with people grasping for human connection, and internet friends became more important than ever. 

Since then, there have been countless discussions about how people have fared with keeping in touch with others during the COVID-19 pandemic — like how families have endured while being separated by continents without the option to travel, and how once solid friendships have waxed and waned without brunches and cocktail hours. 

However, the internet has served more like a proverbial town square than ever before, with many having found themselves using online spaces to create and cultivate internet friends more over the last year and a half than ever before. As the country starts hesitantly opening, the looming question overall is, what will these online relationships look like when COVID-19 is no more? 

 For Will F. Coakley, a deputy constable from Austin, Texas, the highs of her online friend groups she made on Zoom and Marco Polo have already dissipated. 

“My COVID circle is no more,” she said. “I’m 38, so people my age often have spouses and children.” 

Coakley found online platforms to be a refreshing reprieve from her demanding profession that served at the frontlines of the pandemic. Just as she was getting accustomed to ‘the new normal,’ her routines once again changed, with many online friends falling out of touch as cities and towns began to experiment with opening. 

Coakley has not met anyone from her COVID circle in person, and any further communication is uncertain, boding even worse than the potential dissolutions of real-life friendships reported on throughout the year. 

“In a perfect world, we would hope that things opening up would mean that you could start to meet up with your online friends in person. However, many people will experience a transition in their social circle as they start allocating more of their emotional resources to in-person interactions.” said Kyler Shumway, PsyD, a clinical psychologist and author of The Friendship Formula: How to Say Goodbye to Loneliness and Discover Deeper Connection. “You may spend less time with your online people and more time with coworkers, friends, and family that are in your immediate area.” 

Looking back, many social apps themselves similarly spiked during the time of the lockdown and are now seeing use fall. The invite-only, social networking app Clubhouse launched in March 2020. It quickly gained popularity amid the height of the pandemic, having amassed 600,000 registered users by December 2020 and 8.1 million downloads by mid- February 2021.

The original fervor over Clubhouse has waned as fewer people are cooped up indoors. While many people still use the platform for various professional purposes or niche hobbies, its day-to-day usership has dropped significantly. 

Olivia B. Othman, 38, a Project Assistant in Wuppertal, Germany developed friendships online during the pandemic through Clubhouse as well as through a local app called Spontacts. She has been able to meet people in person as her area has begun to open and said she found the experience to be liberating.

While Othman already had experience with developing close personal relationships online, the pandemic prompted a unique perspective for her, encouraging her to invest in new devices for better communication.

Overall, she has fared well with sustaining her online friendships. 

“I have dropped some [people] but also found good people among them,” Othman said.

Othman wasn’t alone in turning to apps for friendship and human connection. Facebook and Instagram were among the most downloaded apps in 2020, according to the Business of Apps.  Facebook had 2.85 billion monthly active users as of the first quarter of 2021, compared to 2.60 billion during the first quarter of 2020. While Instagram went from 1 billion monthly active users in the first quarter of 2020 to 1.07 billion monthly active users as of the first quarter of 2021. And Twitter grew from 186 million users to 199 million users since the pandemic started, according to Twitter’s first quarter earnings report..

Apps such as TikTok and YouTube were popular outlets for creating online friendship in 2020; however, their potential for replicating the emotional fulfillment that comes from interpersonal relationships is limited, as Shumway said, “the unmet need remains unmet.”  

“Many online spaces offer synthetic connections. Instead of spending time with a friend playing a game online or going out to grab coffee, a person might be tempted to watch one of their favorite Youtubers or scroll through TikTok for hours on end,” Shumway said. “These kinds of resources provide a felt sense of relationship – you feel like you’re part of something. But then when you turn off your screen, those feelings of loneliness will come right back.”

“Relationships that may have formed over the past year through online interactions, my sense is that those will continue to last even as people start to reconnect in person. Online friendships have their limits, but they are friendships nonetheless,” Shumway said. 

Zach Fox, 29, a software engineer has maintained long-distance friendships thanks in large part to online gaming, an important social connection that carried on from before the pandemic. 

“We would text chat with each other most of the time, and use voice chat when playing video games together,” he said.

While he is excited about seeing friends and family again as restrictions lift, Fox feels his online friendships just as strong. 

“I feel closer to some of my online friends than I do to some of my ‘offline’ friends,” he said. “With several exceptions, such as my relationship with my fiancée, I tend to favor online friendships because I have the opportunity to be present with and spend quality time with my online friends more often than I can spend time with IRL friends.”

Ultimately, many are finding less anxiousness and more excitement in the prospect of returning to the real world, even if some interaction may be awkward. Both Coakley and Othman stated they favored in-person meetings to online interactions, despite having enjoyed the times they had with many online friends.

“As you make these choices, make sure to communicate openly and honestly. Rather than letting a friendship slowly decay through ghosting, consider being real and explaining to them what is happening for you. You might share that you are spending more time with people in person and that you have less energy for online time with them,” Shumway said.  

As things change Coakley has found other connections to keep herself grounded. Her mental health team comprises a counselor she has sessions with online but has only met in person once. She admitted to being more enthusiastic about her counselor who she meets with in person regularly. 

“I hate having a screen between them and me. It’s more intimate and a shared experience in person,” she said.

Despite not keeping up with her pandemic friends, Coakley does have other online friends that she knew before the pandemic with whom she has close connections. 

“At the very least, my [online] connections with [folks and with] Black women have developed into actual friendships, and we have plans on meeting in person,” she said. “We’ve become an integral part of each other’s lives. Like family, almost.”

The Rust Programming Language Blog: Announcing Rust 1.55.0

Thursday 9th of September 2021 12:00:00 AM

The Rust team is happy to announce a new version of Rust, 1.55.0. Rust is a programming language empowering everyone to build reliable and efficient software.

If you have a previous version of Rust installed via rustup, getting Rust 1.55.0 is as easy as:

rustup update stable

If you don't have it already, you can get rustup from the appropriate page on our website, and check out the detailed release notes for 1.55.0 on GitHub.

What's in 1.55.0 stable Cargo deduplicates compiler errors

In past releases, when running cargo test, cargo check --all-targets, or similar commands which built the same Rust crate in multiple configurations, errors and warnings could show up duplicated as the rustc's were run in parallel and both showed the same warning.

For example, in 1.54.0, output like this was common:

$ cargo +1.54.0 check --all-targets Checking foo v0.1.0 warning: function is never used: `foo` --> src/ | 9 | fn foo() {} | ^^^ | = note: `#[warn(dead_code)]` on by default warning: 1 warning emitted warning: function is never used: `foo` --> src/ | 9 | fn foo() {} | ^^^ | = note: `#[warn(dead_code)]` on by default warning: 1 warning emitted Finished dev [unoptimized + debuginfo] target(s) in 0.10s

In 1.55, this behavior has been adjusted to deduplicate and print a report at the end of compilation:

$ cargo +1.55.0 check --all-targets Checking foo v0.1.0 warning: function is never used: `foo` --> src/ | 9 | fn foo() {} | ^^^ | = note: `#[warn(dead_code)]` on by default warning: `foo` (lib) generated 1 warning warning: `foo` (lib test) generated 1 warning (1 duplicate) Finished dev [unoptimized + debuginfo] target(s) in 0.84s Faster, more correct float parsing

The standard library's implementation of float parsing has been updated to use the Eisel-Lemire algorithm, which brings both speed improvements and improved correctness. In the past, certain edge cases failed to parse, and this has now been fixed.

You can read more details on the new implementation in the pull request description.

std::io::ErrorKind variants updated

std::io::ErrorKind is a #[non_exhaustive] enum that classifies errors into portable categories, such as NotFound or WouldBlock. Rust code that has a std::io::Error can call the kind method to obtain a std::io::ErrorKind and match on that to handle a specific error.

Not all errors are categorized into ErrorKind values; some are left uncategorized and placed in a catch-all variant. In previous versions of Rust, uncategorized errors used ErrorKind::Other; however, user-created std::io::Error values also commonly used ErrorKind::Other. In 1.55, uncategorized errors now use the internal variant ErrorKind::Uncategorized, which we intend to leave hidden and never available for stable Rust code to name explicitly; this leaves ErrorKind::Other exclusively for constructing std::io::Error values that don't come from the standard library. This enforces the #[non_exhaustive] nature of ErrorKind.

Rust code should never match ErrorKind::Other and expect any particular underlying error code; only match ErrorKind::Other if you're catching a constructed std::io::Error that uses that error kind. Rust code matching on std::io::Error should always use _ for any error kinds it doesn't know about, in which case it can match the underlying error code, or report the error, or bubble it up to calling code.

We're making this change to smooth the way for introducing new ErrorKind variants in the future; those new variants will start out nightly-only, and only become stable later. This change ensures that code matching variants it doesn't know about must use a catch-all _ pattern, which will work both with ErrorKind::Uncategorized and with future nightly-only variants.

Open range patterns added

Rust 1.55 stabilized using open ranges in patterns:

match x as u32 { 0 => println!("zero!"), 1.. => println!("positive number!"), }

Read more details here.

Stabilized APIs

The following methods and trait implementations were stabilized.

The following previously stable functions are now const.

Other changes

There are other changes in the Rust 1.55.0 release: check out what changed in Rust, Cargo, and Clippy.

Contributors to 1.55.0

Many people came together to create Rust 1.55.0. We couldn't have done it without all of you. Thanks!


Anna Harren was a member of the community and contributor to Rust known for coining the term "Turbofish" to describe ::<> syntax. Anna recently passed away after living with cancer. Her contribution will forever be remembered and be part of the language, and we dedicate this release to her memory.

Hacks.Mozilla.Org: Time for a review of Firefox 92

Wednesday 8th of September 2021 03:17:15 PM

Release time comes around so quickly! This month we have quite a few CSS updates, along with the new Object.hasOwn() static method for JavaScript.

This blog post provides merely a set of highlights; for all the details, check out the following:

CSS Updates

A couple of CSS features have moved from behind a preference and are now available by default: accent-color and size-adjust.


The accent-color CSS property sets the color of an element’s accent. Accents appear in elements such as a checkbox or radio input. It’s default value is auto which represents a UA-chosen color, which should match the accent color of the platform. You can also specify a color value. Read more about the accent-color property here.


The size-adjust descriptor for @font-face takes a percentage value which acts as a multiplier for glyph outlines and metrics. Another tool in the CSS box for controlling fonts, it can help to harmonize the designs of various fonts when rendered at the same font size. Check out some examples on the size-adjust descriptor page on MDN.

And more…

Along with both of those, the break-inside property now has support for values avoid-page and avoid-column, the font-size-adjust property accepts two values and if that wasn’t enough system-ui as a generic font family name for the font-family property is now supported.

break-inside property on MDN

font-size-adjust property on MDN

font-family property on MDN

Object.hasOwn arrives

A nice addition to JavaScript is the Object.hasOwn() static method. This returns true if the specified property is a direct property of the object (even if that property’s value is null or undefined). false is returned if the specified property is inherited or not declared. Unlike the in operator, this method does not check for the specified property in the object’s prototype chain.

Object.hasOwn() is recommended over Object.hasOwnProperty() as it works for objects created using Object.create(null) and with objects that have overridden the inherited hasOwnProperty() method.

Will Kahn-Greene: Mozilla: 10 years

Wednesday 8th of September 2021 02:28:47 PM

It's been a long while since I wrote Mozilla: 1 year review. I hit my 10-year "Moziversary" as an employee on September 6th. I was hired in a "doubling" period of Mozilla, so there are a fair number of people who are hitting 10 year anniversaries right now. It's interesting to see that even though we're all at the same company, we had different journeys here.

I started out as a Software Engineer or something like that. Then I was promoted to Senior Software Engineer and then Staff Software Engineer. Then last week, I was promoted to Senior Staff Software Engineer. My role at work over time has changed significantly. It was a weird path to get to where I am now, but that's probably a topic for another post.

I've worked on dozens of projects in a variety of capacities. Here's a handful of the ones that were interesting experiences in one way or another:

  • SUMO ( Mozilla's support site

  • Input: Mozilla's feedback site, user sentiment analysis, and Mozilla's initial experiments with Heartbeat and experiments platforms

  • MDN Web Docs: documentation, tutorials, and such for web standards

  • Mozilla Location Service: Mozilla's device location query system

  • Buildhub and Buildhub2: index for build information

  • Socorro: Mozilla's crash ingestion pipeline for collecting, processing, and analyzing crash reports for Mozilla products

  • Tecken: Mozilla's symbols server for uploading and downloading symbols and also symbolicating stacks

  • Standup: system for reporting and viewing status

  • FirefoxOS: Mozilla's mobile operating system

I also worked on a bunch of libraries and tools:

  • siggen: library for generating crash signatures using the same algorithm that Socorro uses (Python)

  • Everett: configuration library (Python)

  • Markus: metrics client library (Python)

  • Bleach: sanitizer for user-provided text for use in an HTML context (Python)

  • ElasticUtils: Elasticsearch query DSL library (Python)

  • mozilla-django-oidc: OIDC authentication for Django (Python)

  • Puente: convenience library for using gettext strings in Django (Python)

  • crashstats-tools: command line tools for accessing Socorro APIs (Python)

  • rob-bugson: Firefox addon that adds Bugzilla links to GitHub PR pages (JS)

  • paul-mclendahand: tool for combining GitHub PRs into a single branch (Python)

  • Dennis: gettext translated strings linter (Python)

I was a part of things:

I've given a few presentations 1:


I thought there were more, but I can't recall what they might have been.

I've left lots of FIXME notes everywhere.

I made some stickers:

"Soloists" sticker (2017)

"Ted maintained this" sticker (2019)

I've worked with a lot of people and created some really warm, wonderful friendships. Some have left Mozilla, but we keep in touch.

I've been to many work weeks, conferences, summits, and all hands trips.

I've gone through a few profile pictures:

Me in 2011

Me in 2013

Me in 2016 (taken by Erik Rose in London)

Me in 2021

I've built a few desks, though my pictures are pretty meagre:

Rough sketch of a standing desk

Standing desk and a stool I built

My current chaos of a desk

I've written lots of blog posts on status, project retrospectives, releases, initiatives, and such. Some of them are fun reads still.

It's been a long 10 years. I wonder if I'll be here for 10 more. It's possible!

  • Announcement : An AArch64 (Arm64) Darwin port is planned for GCC12

    As many of you know, Apple has now released an AArch64-based version of macOS and desktop/laptop platforms using the ‘M1’ chip to support it. This is in addition to the existing iOS mobile platforms (but shares some of their constraints). There is considerable interest in the user-base for a GCC port (starting with - and, of great kudos to the gfortran team, one of the main drivers is folks using Fortran. Fortunately, I was able to obtain access to one of the DTKs, courtesy of the OSS folks, and using that managed to draft an initial attempt at the port last year (however, nowhere near ready for presentation in GCC11). Nevertheless (as an aside) despite being a prototype, the port is in use with many via hombrew, macports or self-builds - which has shaken out some of the fixable bugs. The work done in the prototype identified three issues that could not be coded around without work on generic parts of the compiler. I am very happy to say that two of our colleagues, Andrew Burgess and Maxim Blinov (both from embecosm) have joined me in drafting a postable version of the port and we are seeking sponsorship to finish this in the GCC12 timeframe. Maxim has a lightning talk on the GNU tools track at LPC (right after the steering committee session) that will focus on the two generic issues that we’re tackling (1 and 2 below). Here is a short summary of the issues and proposed solutions (detailed discussion of any of the parts below would better be in new threads).

  • Apple Silicon / M1 Port Planned For GCC 12 - Phoronix

    Developers are hoping for next year's GCC 12 release they will have Apple AArch64 support on Darwin in place for being able to support Apple Silicon -- initially the M1 SoC -- on macOS with GCC. LLVM/Clang has long been supporting AArch64 on macOS given that Apple leverages LLVM/Clang as part of their official Xcode toolchain as the basis for their compiler across macOS to iOS and other products. While the GNU Compiler Collection (GCC) supports AArch64 and macOS/Darwin, it hasn't supported the two of them together but there is a port in progress to change it.

  • Dirk Eddelbuettel: tidyCpp 0.0.5 on CRAN: More Protect’ion

    Another small release of the tidyCpp package arrived on CRAN overnight. The packages offers a clean C++ layer (as well as one small C++ helper class) on top of the C API for R which aims to make use of this robust (if awkward) C API a little easier and more consistent. See the vignette for motivating examples. The Protect class now uses the default methods for copy and move constructors and assignment allowing for wide use of the class. The small NumVec class now uses it for its data member.

  • QML Modules in Qt 6.2

    With Qt 6.2 there is, for the first time, a comprehensive build system API that allows you to specify a QML module as a complete, encapsulated unit. This is a significant improvement, but as the concept of QML modules was rather under-developed in Qt 5, even seasoned QML developers might now ask "What exactly is a QML module". In our previous post we have scratched the surface by introducing the CMake API used to define them. We'll take a closer look in this post.

  • Start using YAML now |

    YAML (YAML Ain't Markup Language) is a human-readable data serialization language. Its syntax is simple and human-readable. It does not contain quotation marks, opening and closing tags, or braces. It does not contain anything which might make it harder for humans to parse nesting rules. You can scan your YAML document and immediately know what's going on. [...] At this point, you know enough YAML to get started. You can play around with the online YAML parser to test yourself. If you work with YAML daily, then this handy cheatsheet will be helpful.

  • Raspberry Pi Weekly Issue #371 - Sir Clive Sinclair, 1940 – 2021

    This week ended with the incredibly sad news of the passing of Sir Clive Sinclair. He was one of the founding fathers of home computing and got many of us at Raspberry Pi hooked on programming as kids. Join us in sharing your Sinclair computing memories with us on Twitter and our blog, and we’ll see you next week.

  • cuplTag battery-powered NFC tag logs temperature and humidity (Crowdfunding) - CNX Software

    Temperature and humidity sensors would normally connect to a gateway sending data to the cloud, the coin-cell battery-powered cuplTag NFC tag instead sends data to your smartphone after a tap. CulpTag is controlled by an MSP430 16-bit microcontroller from Texas Instruments which reads and stores sensor data regularly into an EEPROM, and the data can then be read over NFC with the tag returning an URL with the data from the sensor and battery, then display everything on the phone’s web browser (no app needed).

  • A first look at Microchip PolarFire SoC FPGA Icicle RISC-V development board - CNX Software

    Formally launched on Crowd Supply a little over a year ago, Microchip PolarFire SoC FPGA Icicle (codenamed MPFS-ICICLE-KIT-ES) was one of the first Linux & FreeBSD capable RISC-V development boards. The system is equipped with PolarFire SoC FPGA comprised a RISC-V CPU subsystem with four 64-bit RISC-V (RV64GC) application cores, one 64-bit RISC-V real-time core (RV64IMAC), as well as FPGA fabric. Backers of the board have been able to play with it for several months ago, but Microchip is now sending the board to more people for evaluation/review, and I got one of my own to experiment with. That’s good to have a higher-end development board instead of the usual hobbyist-grade board. Today, I’ll just have a look at the kit content and main components on the board before playing with Linux and FPGA development tools in an upcoming or two posts.

  • What is IoT device management?

    Smart devices are everywhere around us. We carry one in our pocket, watch movies on another while a third cooks us dinner. Every day there are thousands of new devices connecting to the Internet. Research shows that by 2025, more than 150,000 IoT devices will come online every minute. With such vast numbers it is impossible to keep everything in working order just on your own. This brings the need for IoT device management. But what is IoT device management? To answer this question we first need to understand what the Internet of Things (IoT) is.

  • Experimenting Is Underway For Rust Code Within Mesa - Phoronix

    Longtime Mesa developer Karol Herbst who has worked extensively on the open-source NVIDIA "Nouveau" driver as well as the OpenCL/compute stack while being employed by Red Hat is now toying with the idea of Rust code inside Mesa.  Karol Herbst has begun investigating how Rust code, which is known for its memory safety and concurrency benefits, could be used within Mesa. Ultimately he's evaluating how Rust could be used inside Mesa as an API implementation as well as for leveraging existing Mesa code by Rust. 

  • KWinFT Continues Working On WLROOTS Render, Library Split

    KWinFT as a fork of KDE's KWin X11/Wayland compositor code continues making progress on driving fundamental display improvements and ironing out the Wayland support.  KWinFT has been transitioning to use WLROOTS for its Wayland heavy-lifting and that process remains ongoing. KWinFT has also been working on splitting up its library code to make it more manageable and robust.  Among the features still desired by KWinFT and to be worked on include input methods, graphical tablet support, and PipeWire video stream integration. Currently there are two full-time developers working on the project but they hope to scale up to four to five full-time developers. 

  • Raytracing Starting to Come Together – Bas Nieuwenhuizen – Open Source GPU Drivers

    I am back with another status update on raytracing in RADV. And the good news is that things are finally starting to come together. After ~9 months of on and off work we’re now having games working with raytracing.

  • Multiple Games Are Now Working With RADV's Ray-Tracing Code - Phoronix

    Not only is Intel progressing with its open-source ray-tracing driver support but the Mesa Radeon Vulkan driver "RADV" has been rounding out its RT code too and now has multiple games correctly rendering. Bas Nieuwenhuizen has been spearheading the RADV work on Vulkan ray-tracing support and after more than a half-year tackling it things are starting to fall into place nicely.Games such as Quake II RTX with native Vulkan ray-tracing are working along with the game control via VKD3D-Proton for going from Direct3D 12 DXR to Vulkan RT. Metro Exodus is also working while Ghostrunner and Doom Eternal are two games tested that are not yet working.
