New free online course: #Exasol Virtual Schemas

Virtual Schemas integrate foreign data sources into the Exasol database. They enable Exasol to become the central source of truth in your data warehouse landscape.

We added another free online learning course to our curriculum that explains how to deal with Virtual Schemas. Like the others, it comes with many hands-on practices to support a good learning experience. It also contains many demo videos like this one:

I recorded this clip (like most of the others) myself, but this time we decided to do a voice-over by native professional speakers.

Certification exams are free, also for this new course. When you complete the majority of hands-on labs in the course, you get one free certification exam granted per person and per course.

What are you waiting for? Come and get it!

Eleven Table Tennis: Basics

Assuming you are an IRL player who wants to get as close to the real thing as possible, that’s what I’d recommend:

Make sure you have enough space to play

The green box is your playing space. It should be a square of 2.50 m X 2.50 m ideally. Make sure to leave some space at the front, so you can reach balls close to the net and even a little across the net. Otherwise you may become a victim of ghost serves. Leave enough room at the sides – some opponents play angled, just like IRL.

If you don’t have enough space for this setup – maybe you shouldn’t play multiplayer mode then. You can still have fun, playing against the ballmachine or against the AI. Actually, I think it’s worth the money even in that case.

Use the discord channel

The Eleven TT community is on this discord channel:

I recommend you register there and use the same or a similar name as the name you have in the game. For example, I’m Uwe on discord and uwe. in the game (because the name uwe was already taken). This is handy to get advice from more experienced players, also the game developers are there. They are very responsive and keen to improve Eleven TT even more, according to your feedback.

There’s a preview version presently, that has improved tracking functionality. You can just ask the developers there to get you this preview version. I did, and I find it better than the regular version, especially for fast forehand strokes.

Setup your paddle

When you have the Sanlaki paddle adapter (as recommended in the previous post), go to the menu and then to Paddle Settings:

Click on Paddle Position and select the Sanlaki Adapter:

As an IRL player, you may start with an Advanced Paddle Surface:

Se how that works for you. Bounciness translates to the speed of your blade. An OFF ++ blade would be maximum bounciness. Spin is self-explaining. You have no tackiness attribute, though. Throw Coefficient translates to the sponge thickness. The higher that value, the thicker the sponge.


This takes some time to get used to. You need to press the trigger on the left controller to first “produce” a ball, then you throw it up and then release the trigger again to release the ball. Took me a while to practice that and still sometimes I fail to release the ball as smoothly as I would like to.

What I like very much: You have a built-in arbiter, who makes sure your serve is legal according to the ITTF rules. That is applied for matches in multiplayer mode as well as for matches in single player mode. But not in free hit mode! Check out the Serve Practice:

It tells you what went wrong in case:

Remove AI Spin Lock

I recommend you practice with the AI opponent in single player mode for a while. It has spin lock on per default, which means it will never produce any side spin. I find that unrealistic. After some practicing against the AI in single player mode, you’re ready for matches in multiplayer mode against other human opponents.

Getting started with VR Table Tennis

Difficult to play table tennis in real life (IRL) these days. I found this simulation:

Eleven TT is really close to IRL table tennis – I’m a club player myself and I was surprised how close this comes to reality! Check this YouTube channel to get an idea about the quality of the simulation. The guy who uploads these videos might be a bit too competitive sometimes, but he’s clearly a good player and challenges the best available opponents regularly.

The game itself costs 20 Euro, which is a real bargain for the great quality you get. Many will have no VR headset, though, and that’s a bit more expensive. I recommend the Oculus Quest 2 that works autonomously without a workstation and without wires. That’s about 400 Euro.

As IRL player, you will want to transfer as much of your skills as possible, which is why a paddle adapter is helpful. I recommend the Sanlaki F8 adapter.

They sell them, but also provide the 3d printer files for free so you can print it yourselves or let someone else print it for you. I ordered mine for 15 Euro (shipping included) via Treatstock (Black PLA, 20% fill) and find it quite useful.

So overall, you have to spend about 500 Euro to get started, but it’s totally worth it in my opinion:

A TT table + ballmachine would cost you more (if you have the space to place it at home). That is included in the game, as well as an AI opponent with configurable levels. That alone is worth it already. Given the choice, I’d favor the simulation over the IRL ballmachine – and I had one before, so I can compare.

In multiplayer mode, you can play against other human opponents across the world. Whenever you want to play table tennis, you’ll find an opponent without having to leave the comfort of your home. And you will never have to pick up a ball from the floor again 😉
