Luet oppimateriaalin englanninkielistä versiota. Mainitsit kuitenkin taustakyselyssä osaavasi suomea. Siksi suosittelemme, että käytät suomenkielistä versiota, joka on testatumpi ja hieman laajempi ja muutenkin mukava.

Suomenkielinen materiaali kyllä esittelee englanninkielisetkin termit.

Kieli vaihtuu A+:n sivujen yläreunan painikkeesta. Tai tästä: Vaihda suomeksi.

Lab Sessions

Teaching assistants support your programming studies at lab sessions, also known simply as “labs”. There are several labs every day between September 8th and December 7th, 2022. This is where you can come to discuss programming with the course staff and get help on the assignments.

Most labs are at the Maarintalo building (Sähkömiehentie 3, Espoo) in the classroom Maari-A. However, some of the sessions are instead online on Zoom, as explained below on this page. Please note that in certain weeks, the on-campus labs are in a different classroom than usual, which is also detailed below.

(In addition to the labs; we provide a Piazza discussion board and a group on Telegram; see Chapter 1.1.)

Aalto students only, sorry!

The lab sessions described on this page are only open to students with an Aalto user account. Resources permitting, we might choose to open some of the sessions to other students as well, in which case we’ll announce that separately. The Piazza forum and Telegram group are there for all students, including those external to Aalto.

The sessions start a quarter past the indicated hour, but you can come and go as you please. There’s no set agenda: you can come to a session to work on the assignments and ask for advice as the need arises.

Participation is voluntary but highly recommended. You don’t need to — and can’t — sign up in advance.

The assistants can help you in English, Finnish, and (at some sessions) Swedish.

Online Labs on Zoom

Some of the labs will be online as Zoom video calls where students can discuss their program individually with a teaching assistant. We’ll use A+’s Lab Queue feature to allocate turns to each student (or pair of students).

If you are unfamiliar with Zoom, please try it out well in advance before joining one of the online labs.

Setting up Zoom

Install Zoom on your computer as per Aalto’s Zoom Quick Guide.

Zoom may be initially configured to mute any teaching assistants that enter your Zoom meetings. Please ensure that this is not the case:

1. Go to aalto.zoom.us and log in with your Aalto account.

2. In the left-hand menu, choose Settings.

3. Scroll down until you find Mute participants upon entry. Make sure that the setting is not enabled.

Test your video and audio in advance to make sure they’re working in Zoom.

Zoom in the browser

Instead of the separate Zoom app, you can use Zoom in your web browser. If you do, here’s how to launch it:

1. Go to aalto.zoom.us.

2. Press Host.

3. In the dialog that pops up, press Start from your browser.

4. Select Join Audio by Computer.

5. A Zoom meeting starts. You can now copy the invitation link to the clipboard by selecting Manage Participants → Invite → Copy URL.

If you use Zoom in the browser, you’ll also need to adjust your browser settings to let Zoom access your microphone and camera.

Joining an online lab

You don’t have to (and can’t) sign up in advance. When you want to talk to a teaching assistant, do the following.

Before you join the queue, start a Zoom meeting:

1. Open Zoom and select New Meeting.

2. Select Join with Computer Audio. Your meeting is now active but with only you as a participant. Others can join if they have an invite link, more on which below.

With the Zoom meeting running, enter the Lab Queue:

1. Make sure that the program, ebook page, or other material that you wish to discuss is ready for viewing on your computer.

2. Here in A+, select Lab Queue in the menu.

3. The Lab Queue prompts you for a video link. Put in the invite link from Zoom. You can copy this link to your clipboard by selecting, in Zoom, Participants → Invite → Copy invite link.

   • If you’re working together with a pair, make sure to share the link with them, too, so that you’re both present when the assistant joins the meeting.

4. In the drop-down menu, select which language you’d prefer to be advised in.

5. Confirm the selections, and you’re in the queue. An assistant will join your Zoom meeting sooner or later, depending on the length of the queue.

Especially when the queue is long, the assistant cannot spend very long in one meeting. For that reason, too, please be prepared when it’s your turn!

Screen-sharing and mics on Zoom

In order to help you, the assistant will typically need to see the program that you’re working on. You can share your computer’s screen with the assistant by selecting, at Zoom’s bottom edge, Share → Screen and confirming with Share.

In Zoom’s bottom-left corner, there’s a little microphone symbol. Check to see that your microphone isn’t muted; or if it is, click the symbol or press Alt + A. If you can’t hear the assistant, make sure they aren’t muted by checking Participants at Zoom’s bottom edge. When you mouse over the assistant’s name in that list, you’ll see a Mute/Unmute button. While resolving audio trouble, you can resort to Zoom’s textual Chat, too.

Credits

Thousands of students have given feedback and so contributed to this ebook’s design. Thank you!

The ebook’s chapters, programming assignments, and weekly bulletins have been written in Finnish and translated into English by Juha Sorva.

The appendices (glossary, Scala reference, FAQ, etc.) are by Juha Sorva unless otherwise specified on the page.

The automatic assessment of the assignments has been developed by: (in alphabetical order) Riku Autio, Nikolas Drosdek, Joonatan Honkamaa, Antti Immonen, Jaakko Kantojärvi, Niklas Kröger, Kalle Laitinen, Teemu Lehtinen, Jaakko Nakaza, Strasdosky Otewa, Timi Seppälä, Teemu Sirkiä, Anna Valldeoriola Cardó, and Aleksi Vartiainen.

The illustrations at the top of each chapter, and the similar drawings elsewhere in the ebook, are the work of Christina Lassheikki.

The animations that detail the execution Scala programs have been designed by Juha Sorva and Teemu Sirkiä. Teemu Sirkiä and Riku Autio did the technical implementation, relying on Teemu’s Jsvee and Kelmu toolkits.

The other diagrams and interactive presentations in the ebook are by Juha Sorva.

The O1Library software has been developed by Aleksi Lukkarinen and Juha Sorva. Several of its key components are built upon Aleksi’s SMCL library.

The pedagogy of using O1Library for simple graphical programming (such as Pic) is inspired by the textbooks How to Design Programs by Flatt, Felleisen, Findler, and Krishnamurthi and Picturing Programs by Stephen Bloch.

The course platform A+ was originally created at Aalto’s LeTech research group as a student project. The open-source project is now shepherded by the Computer Science department’s edu-tech team and hosted by the department’s IT services. Markku Riekkinen is the current lead developer; dozens of Aalto students and others have also contributed.

The A+ Courses plugin, which supports A+ and O1 in IntelliJ IDEA, is another open-source project. It has been designed and implemented by various students in collaboration with O1’s teachers.

For O1’s current teaching staff, please see Chapter 1.1.

Additional credits for this page

Niklas Kröger wrote the instructions for Zoom labs, drawing on similar guides by Mikko Kivelä and Kerttu Pollari-Malmi; Juha Sorva translated the instructions to English.
