  • DNS-over-HTTPS (DoH) Update – Detecting Managed Networks and User Choice

    At Mozilla, we are continuing to experiment with DNS-over-HTTPS (DoH), a new network protocol that encrypts Domain Name System (DNS) requests and responses. This post outlines a new study we will be conducting to gauge how many Firefox users in the United States are using parental controls or enterprise DNS configurations.

    With previous studies, we have tried to understand the performance impacts of DoH, and the results have been very promising. We found that DoH queries are typically the same speed or slightly slower than DNS queries, and in some cases can be significantly faster. Furthermore, we found that web pages that are hosted by Akamai–a content distribution network, or “CDN”–have similar performance when DoH is enabled. As such, DoH has the potential to improve user privacy on the internet without impeding user experience.

    Now that we’re satisfied with the performance of DoH, we are shifting our attention to how we will interact with existing DNS configurations that users have chosen.  For example, network operators often want to filter out various kinds of content. Parents and schools in particular may use “parental controls”, which block access to websites that are considered unsuitable for children. These controls may also block access to malware and phishing websites. DNS is commonly used to implement this kind of content filtering.

  • New CSS Features in Firefox 68

    Firefox 68 landed earlier this month with a bunch of CSS additions and changes. In this blog post we will take a look at some of the things you can expect to find, that might have been missed in earlier announcements.

  • How to Build a Career in Artificial Intelligence and Machine Learning?

    Math is just one of the skillsets that aspiring AI and ML professionals are expected to have. This is only one half the requirement, the other half is one’s expertise in programming languages, such as Java, C++, Python, and R.

    While C++ helps engineers increase the speed of their coding process, Python will help them understand and create complex algorithms. Python is also the go-to choice for ML developers, and also offers various libraries and frameworks to ease the process of creating an AI model. Similarly, R and Java help professionals understand stats and implement mappers, respectively. They are important considering the role of visualization in explaining AI.

  • Company That Buys Zero-Day Hacks Now Wants Exploits for Popular VPNs

    Uh oh. An infamous company that pays thousands of dollars for iOS and Android hacking techniques is now out to acquire zero-day exploits for three popular VPN services. Zerodium today sent out a tweet calling for “zero-days” or publicly unknown attacks that work against ExpressVPN, NordVPN, or Surfshark. The attacks must be capable of leaking information from the VPNs, such as a computer’s IP address. Zerodium will also pay for exploits that can trigger a VPN to remotely execute computer code.

  • Verizon 'Visible' Wireless Accounts Hacked, Exploited To Buy New iPhones

    Wireless subscribers of Verizon's Visible prepaid service received a rude awakening after hackers compromised their account, then ordered expensive new iPhones on their dime. Last week a company statement indicated that "threat actors were able to access username/passwords from outside sources," then utilize that access to login to Visible customer accounts. Hacked users say the attackers then utilized that access to order expensive kit, and, initially, getting Visible to do anything about it was a challenge:

Stable vs. Bleeding-Edge Linux Distros: Which One Should You Choose?

Linux distributions have multiple ways of delivering software to their users. But which one should you go for—stability or the latest software? One of the major choices that many Linux users face when choosing a Linux distribution is its stability, or how much the software changes. Some distros favor stable, tried-and-true software while others will include newer software that may not be as reliable, also known as "bleeding-edge," a play on "cutting-edge." So, which one should you choose? Let's find out. Read more

This week in NeoChat

Last Saturday we had an improvised NeoChat mini development sprint in a small hotel room in Berlin in the occasion of the 25th anniversary of KDE. In a good KDE tradition, Carl spent this time on improving NeoChat settings. He ported both the NeoChat general settings and the specific room settings to the new Kirigami.CategorizedSetting component. Tobias fixed a lot of papercuts and now the power level should be fetched correctly, we show the number of joined users instead of joined+invited users in the room information pane, the user search is now case insensitive. Nicolas focused on fixing our Android build by making the spellchecking feature compile on Android. Read more
