In our latest podcast miniseries, we spoke to educators live from the CSTA 2025 annual conference in Cleveland, Ohio, to hear their top tips for integrating computer science (CS) into other subjects.

Hello World editor, Meg Wang and the team met teachers in the exhibit hall for real-time reflections and essential teacher tips on teaching cross-curricular CS. They spoke to some amazing educators from across the United States and had a great time interacting with everyone in attendance.
“Meeting teachers and hearing first-hand about their experiences, challenges, and triumphs was invaluable. It was amazing to meet Hello World writers in person, and to also meet future writers. Like I said at the conference, Hello World is for educators, by educators, so that means you! Everyone has valuable experience or useful advice to share, and we’re here to help you amplify that.” – Meg Wang, editor of the Hello World magazine

Lisa’s top tip for integrating computer science into your lessons is to start with topics that you’re passionate about. If you’re not a CS teacher yourself, Lisa suggests finding a colleague who teaches the subject. She advises having a chat with them to explore how you can include CS concepts into subjects you’re particularly interested in.
“I guarantee you that they’re going to have something […] to teach [another subject], and it’s going to involve computer science.”
Through peer discussions and collaboration between educators, you’ll discover engaging ways that you can incorporate CS into your teaching. Give it a try the next time you’re chatting to a CS teacher.

Tiffany N. Jones, author of ‘Belonging in Tech’ (featured on page 82 of Hello World Issue 27), shares her top tip to seamlessly integrate computer science into other subjects.
Using the example of a class studying ocean health and pollution, Tiffany shares how you can introduce students to real-world applications of computer science by exploring how sensors and microcontrollers can be used to collect environmental data.
She then suggests exploring how databases and programming languages can be used to analyse and visualise the data that the sensors and microcontrollers have recorded. This not only deepens your learner’s scientific understanding but also demonstrates how computing concepts are used in real-world industry practices.

Rick’s top tip for integrating CS is to first think about your favourite lesson and consider ways that you can introduce computational thinking.
In the podcast, Rick says:
“chances are, computational thinking is already a part of that lesson you’re doing. Call it out to the students, and that’s going to help them to start understanding how computer science is baked into everything we do.”
Rick also offers a great example from his experience as a band teacher. He shares how learning to read a new piece of music is very similar to the steps involved in computational thinking. s
“[You’ve] got to break it down. There’s abstraction. You’ve got to figure out the sequencing, and you create the way that you’re going to learn it. And that is all part of computational thinking.”
This approach shows students that CS isn’t just coding; it’s a way of thinking that can be applied across disciplines.

Are you looking to strengthen digital literacy in your classroom? In the latest episode of the Hello World podcast, three experienced teachers from the USA and the UK share practical tips they’ve used in their classrooms to help their students build digital literacy. Whether you’re just getting started with digital literacy or looking for new ideas, the episode is full of real-world advice you can apply straight away.

The episode also marks the launch of a new mini-series on the Hello World podcast focusing on digital literacy. Throughout the series, which totals three episodes, we’ll continue conversations that feature in the latest issue of the Hello World magazine, sharing expert insights and real-world examples from educators who are integrating digital literacy into their classrooms.
So tune in this week, then stay tuned!
We’ve got tips from three teachers whose articles feature in Hello World’s newest magazine issue.
Get ready for some top tips from Katie Dahlman, a preschool teacher and Digital Learning Specialist in Bloomington Public Schools in Minnesota, USA. With over 16 years of experience as an early childhood educator, Katie has dedicated her time to developing engaging computer science (CS) lessons for young learners.

Katie believes that digital literacy starts with building foundational skills to prepare students for their roles as digital citizens. One of the tips Katie shares in the episode emphasises the importance of integrating computational thinking into the classroom:
“My second tip for enhancing digital literacy in your classroom is to integrate computational thinking skills and vocabulary into your existing curriculum.”
Read Katie’s article ‘Tech tinkering and teamwork’ on pages 52–53 of Hello World, issue 26.
We also hear from Curt Hitchens, a computer science teacher at Saddle Ridge Elementary and Middle School in Rock Spring, Georgia, USA. Since 2018, Curt has been teaching computer science and now serves as a Virtual CS Specialist for the Georgia Department of Education.

Curt explains in the podcast that digital literacy is about equipping students with the necessary skills to use technology effectively in everyday situations and the workplace. He also shares an important tip for teachers, encouraging them to give students regular chances to engage in hands-on learning:
“Make sure that you’re providing consistent opportunities for creation and exploration within your classes.”
Read Curt’s article ‘Computer science opportunities in rural schools’ on pages 46–47 of Issue 26.
The episode also features Halima Bhayat, the Head of Computing and Digital T Levels at Ursuline High School in London, UK. Halima is an Asian Women of Achievement 2021 Finalist, a digit<all> ambassador, an Amazon teacher, and the Computing at School Merton lead for all schools.

With a wealth of experience, she emphasises that digital literacy is more than about using technology — it’s about understanding how the digital world functions, how technology shapes our daily lives, and how it impacts individuals and communities.
One of Halima’s top tips for enhancing digital literacy in the classroom is to focus on touch typing. She believes that students should be equipped with fast and efficient typing skills, as so many tasks today are online.
“My first tip would be to get [your students] touch typing, get them to start becoming faster with their fingers on those keyboards, because lots of things have become online.”
Read Halima’s article ‘From switches to success’ on pages 76–77 of Issue 26.

The /etc/shadow file stores the actual password in encrypted format using a hash (salted) function for the user's account with additional properties related to the user passwords, such as password expiration date or password aging. The /etc/passwd stores usernames and their properties, such as home directory, login shell, and more. The password expiration information for a user is contained in the last six fields. The Linux password expiration for a select user can be disabled by editing the /etc/shadow file. However, I recommend using the chage command for safety reasons. The chage command changes the number of days between password changes and the last password change date. The Linux system uses this information to determine when users must change their passwords.

If you are writing a Bash shell script, you should read command-line arguments into an array for some time. This allows us to process any number of arguments provided when the script is run. This makes the script adaptable to different use cases. Instead of dealing with fixed variables like $1, $2, $3, etc., you can work with any number of arguments more dynamically using bash for loop or bash while loop, depending upon your needs. Arrays make it simple to loop through each argument and perform operations on them, whether basic printing or complex processing. Bash provides a mapfile (readarray command) internal built-in command to read lines from a file into an array variable. Let us see how to use mapfile to read all command line arguments into an array.

CentOS, RHEL (Red Hat Enterprise Linux), Fedora and other clones of RHEL, such as Oracle, Alma, and Rocky, offer support for version pinning. This feature allows developers and system administrators to lock a particular package to a specific version, preventing it from being automatically updated by yum or dnf commands. Sometimes, it is necessary to protect packages from being updated to newer versions to avoid incompatibility issues with your applications. For example, you can lock down PHP version 8.3.6 and avoid using updated PHP version 8.4. Let us see how to lock a package to a specific version, only exclude a package from yum update or dnf update on a CentOS, RHEL, Fedora, and friends.
