Weekly Incubator Update: Tracking Progress from April 10th to April 17th

Waiting for Vietnamese
And the wait still continues...
Team Vietnamese had initially predicted their launch date way too far in the future (2050). And now their revised prediction - 8-Apr-2016 is already past. Can we request ckhadung for an update?

Five in a row!
Lextum8 can now say - five in a row! That is how the EO for ES team has performed in the last five weeks to remain the reigning leader Extraordinaire. I can as well stick the star in the image below against their name. At the same time the rest of the teams have been slow bringing the weekly progress numbers to the abysmally low levels. Something has really got to change in the next few weeks, starting with Team Hindi? Perhaps.

An even earlier edition of WIU this week
My upcoming travel that begins in a few hours, forces me to publish this week's edition once again earlier than the scheduled time. And once again, please let me know if you notice any post haste on my part :)

christian from Team German wrote a week ago:

Wieder ein neuer Baum!

Last year, we launched a major new version of the course, which came with greatly improved metrics, but of course, we weren't able to fix all the problems of the previous tree, and because of technical limitations, a few new problems emerged. The latest tree version, which we have just launched as an A/B test, is just a minor revision. We've fixed a few things here and there and added a couple of words as well as a skill on relative pronouns.

The usual caveats related to A/B tests apply:

If you get the new tree and previously had a golden owl, you'll have to redo those lessons that have been affected by the new tree version.

The A/B test is part of the process of allowing everyone to have the highest quality course. Don't fret if you don't have it yet. If the metrics show that the new version actually is better, you'll get it too in due time.

Monday update (oops)


excuse the slight delay in the update. Over the last week, we added sentences to all the new words we introduced and as promised, these were the final content changes before beta. The final skills we added were words having to do with dates and time, for example idén and tavaly meaning 'this year' and 'last year', respectively.

So this week, the aim is to set up the tree for locking it. I'm in touch with the Duolingo community on what to do exactly and I can hopefully tell you more in the next updates. But I'm fairly confident by now that we'll see the course in action idén!

Another round of thanks to everyone who is patiently waiting for the course!

AndrsBrny from Team Hungarian added 3 days ago:

Fixing a hole

So we're preparing to lock the tree, which means no longer being able to add words, or move skills around. We do have all our words, finally, but we do have to move some skills around.

When "moving" accusatives in the course (which you'll hopefully be more thankful for later than you are now for all our delays), I thought it would be straightforward to move some words from one skill to another. Which it kind of is, but: there are many sentences in a course tree which track the first position you add a given word. And when you move a word to another skill, those links aren't always updated in the way I thought. Nothing much to worry about, but we ended up with some "double" entries (which explains the pushed back beta release date!).

I've also been in touch with the very helpful Duolingo people who said they prefer teams fixing such things by hand than by magic, as that might break more. So that's what we're doing this week, fixing a hole. We've done a fair share of this, but I suspect the Duolingo database might need some time to digest what's happening..

Summary (tl;dr)

We're ironing out a hole in the tree which was the result of some recent useful additions. Don't take the moved release date too seriously, it's just because Duolingo thinks we've added many new words while moving some of them around between skills.

DvirBartov from Team Hebrew wrote yesterday and claimed this week's Star Update Award:



As many of you have probably seen, we've reached 100%!

We made an awesome progress and completed all the sentences and word images (and far beyond =D). The Hebrew course contains 2833 words, which is A LOT. Right now we're finishing some tips and notes, adding more alternate translations, editing hints and waiting for the our course voice.

A special thanks to avrichard, our alpha tester, who is doing a wonderful job testing our course and helping us make the course better. And of course we couldn't reach this point without our awesome team, who has been working day and night, for hours every day, just to make this course better!

Gracias a la introducción de nuestro curso en la app de Duolingo para [móviles/celulares] hemos aumentado en un 36% el total de usuarios... en 1 semana!

El porcentaje de reportes va bajando. Ya estamos navegado por la linea de los 3 reportes/100 usuarios (entre 3.5 y 2 % las últimas 2 semanas).

Aún nos quedan bastantes cosas por corregir. Por favor sigan reportando errores de pronunciación y respuestas que deberían ser aceptadas.

Recuerden que la próxima semana se celebra la Diada de Sant Jordi (23 abril) explicada en la anterior actualización. Que tengan un buen día!

Esta semana fue un poco lenta, yo personalmente estoy estudiando para la universidad D:, pero aún así, 92% y muy cerca! Aunque luego de llegar al 100% se deben volver a revisar todas las oraciones en esperanto para que sean correctas gramaticalmente, se deben revisar todas las traducciones para que muestren el verdadero sentido de la oración en esperanto mostrado de la manera más internacional dentro del mundo hispanoparlante posible, se deben organizar algunas cosas, se tiene que completar la traducción y adaptación de las pistas y ayudas de cada lección, y se tienen que enviar las frases en esperanto para obtener las grabaciones de las mismas.

About Vietnamese:

April 17, 2016

I think it has something to do with audio implementation and/or bug fixing. I have not contacted Duo staffs but I know they are as eager as we all are to release the course. Therefore, waiting a bit more won't hurt. Your patience is appreciated! Happy learning, everyone.

April 17, 2016

Glad to see that everyone is eager for the Vietnamese course ^_^

April 17, 2016

And I'm one of them! :)

April 17, 2016

And there are over 40k people waiting to be notified! So exciting!

I like the Czech team, slow but very steady progress every week, advancing like clockwork towards the April 2017 deadline! They should get a Streak award for always completing their weekly goal of 1%.

April 17, 2016

[deactivated user]

    I am quite sure that the course is going to be very good too, given the amount of work and time they are putting in to the process.

    The wait for Guaraní also continues. It has been at 100% for several weeks in a row, just like Vietnamese!

    April 17, 2016

    [deactivated user]

      ¡Sí! ¡No puedo esperar!

      April 17, 2016

      Come on Vietnamese, I believe in you xD

      April 17, 2016

      I can't wait anymore! I want Vietnamese now!

      April 17, 2016

      It's out!

      April 22, 2016

      I am not surprised that Vietnamese is taking longer than expected. The Irish learners/team have been waiting since mid-December for the step of implementing new audio, which the Vietnamese team was told only takes one week. Understood if they prioritize a new course (though frustrating as we've been waiting four months)... But not surprising that it's taking longer than a week.

      April 17, 2016

      Anyone else notice Klingon has another 2% done now?!?! I think that's more than the past couple months... Go Klingon!

      April 17, 2016

      I think that they were stuck at 21% for 5 months.

      Although I still doubt that they can make there August deadline, I'm grateful to see that they're making some progress.

      April 18, 2016

      All of these courses in the high 90's-100% are going to give me a heart attack. Plus many trees already out are working on their trees 2.0... Duolingo is getting better each day!

      April 17, 2016

      Well said I'm also excited to see what the next language they are going to put in the incubator for english speakers

      April 19, 2016

      Another tree for German ? I was happy to have one golden owl but maybe it will give me the opportunity to redo the tree and therefore, study for my german exam in 5 weeks. Thank you German Team :D !

      April 17, 2016

      Maybe I didn't get the actual B version of the tree, but I only had one lesson to re-do (in Philosophy). I'd be curious to see what changes other people saw.

      April 17, 2016

      Me too actually haha. But it motivated me to golden every skills in German and maybe reach level 25.

      April 17, 2016

      That would be great :-D The German tree is so big, you might get to level 25 just in trying to golden it again. Good luck on your exam too! Du kannst es schaffen!

      April 17, 2016

      Danke sehr :)

      April 17, 2016

      Apparently the Philosophy thing was just a bug. Looks like it is mostly new users that have the new tree (same for Norwegian).

      April 17, 2016

      Maybe Esperanto can start getting the star from the Esperanto flag next to their name ;-) kidding of course, but the symbol goes well with their current progress! Daŭrigu, ni subtenas vin!

      April 17, 2016

      As many as 11 courses - nearly half - not being worked on or having progress only once every few weeks. The incubator has definitelly stalled since its release.

      April 17, 2016

      The automatically generated percentage doesn't include progress on things like these:

      • audio
      • tips & notes
      • learning how to best take advantage of the new feature in the Incubator allowing for concatenation (teaching prefixes, suffixes, etc.)
      • organizing which skills will come in the beginning, which in the middle, and which in the end of the course

      My guess is that many volunteers and staff members decided they want to learn to use the new feature, instead of ignoring that new feature and continuing to add words exactly the same way they did before.

      For example, at Croesus1983B said

      ...We on the Korean Team spent most of this past week reorganizing our tree. Now that the Incubator allows for concatenation, we have decided to change the way we approach a number of skills. These changes, we hope, will help make the learning experience more enjoyable...

      :D :D

      April 18, 2016

      Fair enough, but teams stopped being active weekly at different times and most (all?) before that feature for agglutinating languages was added.

      I do recognise some, like Swahili, have legitimate reasons.

      April 18, 2016

      Duolingo just doesn't seem to prioritize courses moving forward at a steady or even a predictable rate. Just like they don't particularly prioritize managing any other part of the community they've created than the one for schools.

      In a way, it might make more sense to keep the whole alpha phase of the course development under wraps, and only launch a course when it is actually available.

      Of course, you can build up a lot of expectation around an upcoming course, but since not all people on here, and probably hardly anyone not on here, understands and remembers that course building takes time and estimated launch dates can be totally different from actual ones, those expectations can lead to a lot of bad press as well...

      Or, as one wise user has put it, they could have an open alpha phase where any team can try to build a course, from which Duolingo would then pick the best, most ripe, and fastest-moving ones to actually get staff support and move towards the beta phase. (I hope I'm paraphrasing the idea more or less correctly here.)

      April 18, 2016

      Good point about bad press!

      April 19, 2016

      honestly i'm so hyped for greek i can't

      April 17, 2016

      Am I the only one who thinks Duolingo is holding off in order to do a double/triple release possibly between Hebrew, Vietnamese, and Hungarian?

      April 17, 2016

      You aren't the only one, I've seen others suggest things like this.

      However, as a member of Team Hebrew, I can tell you our course won't be released until a fair while later than Vietnamese.

      April 19, 2016

      Thank you for the information.

      April 20, 2016

      Thank you jitengore! 6 months ago I wouldn't have imagined you mentioning me :D (and because of something good)

      April 17, 2016

      You're welcome, Lucas!

      Your team has done a fantastic work and you deserve a mention especially for your timely updates. Good luck for the imminent beta launch!

      April 24, 2016

      Thank you a lot!!

      April 24, 2016


      April 17, 2016

      somebody is hyped o_o

      i feel you bro

      April 17, 2016

      Hey it's in beta now!

      April 22, 2016

      7 hours passed and no one commented on the new "estimated launch date" for the Yiddish course... 8D

      April 17, 2016

      I know! I saw it, but didn't comment because I didn't put a lot of stock in the new completion date.

      With zero progress week after week after week, I guess I just took that date with a grain of salt.

      Yiddish entered the incubator on Feb. 19, 2015, and now, after over one year, they have 8% completed. A completion date more than two years out seems possible (since many courses have been totally completed in less time), but probably just a wild speculation.

      I hope it means that the team has reorganized and is ready to begin work again, though!

      April 17, 2016

      Hey, it's in beta now.

      April 22, 2016

      Do they have a flag to represent Yiddish yet?

      April 17, 2016

      Yes - see . :)

      For more on the Yiddish flag issue, read (about how that black-and-white stripes-and-menorah flag was made up by a Wikipedia user doing a one-man campaign for it, and doesn't really represent anyone else except him himself).

      I also recommend reading (the article has a big picture of that Wikipedia user's flag, and a good explanation of why it's not a good flag for Yiddish).

      April 18, 2016

      April 18, 2016

      Waiting for Romanian like

      April 20, 2016

      Yes I am waiting for those, and Czech too. Actually I just started the reverse tree for Czech so I am not too impatient.

      April 23, 2016

      I hope Vietnamese is released soon.

      Is it possible for the team to contact the admins again? Or is it normal communication can take long?

      April 17, 2016

      I wonder if Duolingo is holding off until Vietnamese, Hebrew, and Greek are all finished so they can do a big release.

      April 17, 2016
      • 1390

      If the Duolingo people are smart, they launch all the courses at the same time, and make a media event out of it...
      On the other hand, the courses are launching in beta. If there appear to be small errors in the courses, new Duolingo'ers might be put off. So attracting too much publicity might not be a good thing after all.

      April 17, 2016

      With all these courses ready for Beta soon, I'm wondering which languages will enter the incubator next. The anticipation!

      April 19, 2016

      I'm so excited for Greek for English!

      April 20, 2016

      Yiddish finally has a completion date! But only one contributor :(

      April 22, 2016

      Thank you for the update! I'm already sooo excited about Czech, even though the estimated launch date is still a year away! XD And I'm happy to see Klingon making progress, too. :-)

      April 17, 2016

      My personal guess for Vietnamese's delay is that the Duolingo staff are having a hard time adding so many letters with marks on them :P

      April 18, 2016

      Did you see the latest update at ? :)

      April 19, 2016

      Wow, good observation! I don't know if it means the course is any closer to being released, though...

      April 19, 2016

      Thanks for sharing! With the instructions, I've easily installed the VN keyboard and ready when DL is :) ! ! ! A reminder for Mac users, you can easily toggle between two keyboards by entering command-space bar.
