ScalaMatsuri 2020 will be an online-only conference.

This is a post written by ScalaMatsuri chair Taisuke Oe (@OE_uia).

We would like to inform you that [ScalaMatsuri 2020] (https://scalamatsuri.org/en), scheduled on October 17th and 18th, 2020, has been an online-only conference.

See: ScalaMatsuri 2020 is postponed to October 17-18, 2020 - ScalaMatsuri blog

Due to the continuing spread of COVID-19 throughout Japan and all over the world, we have decided that going online is essential to ensure both the safety of participants and social interaction. We hope that all Scala enthusiasts will be able to enjoy this opportunity to interact with each other, since these opportunities for interaction have been greatly reduced in the wake of the corona outbreak.

Considering this will be the first time for ScalaMatsuri to be held online, on August 30th, we'll be holding a pre-ScalaMatsuri ,intended to be also a rehearsal, which is an online Lightning Talks meetup. We'll be accepting applications for both speakers and participants by the end of next week.

Edited on August 7th: Now the event page is published.

Pre-ScalaMatsuri LightningTalks online meetup

ScalaMatsuri 2020 Online Overview

At this time, we plan to use Zoom Webinar (sessions) and Discord (announcements, interactions, booths, and party).

The dates and times will continue to be October 17 and 18, 2020 (Japan time).

We will also be holding a pre-ScalaMatsuri event on Sunday, August 30th, with an online Lightning Talks meetup.

Official ScalaMatsuri online shop

This year's T-shirts will be available on the official ScalaMatsuri online shop, which will be open to the public in August. For the first time, we will have multiple colors of T-shirts available for you to choose from, so we hope you'll be able to buy one in your favorite color and use it to celebrate the event.

We will be shipping to both domestic and international destinations, but due to logistical constraints, the colors and specifications of the items may differ slightly. Thank you in advance for your understanding.

Ticket Price Revisions.

Due to major changes in online logistics, we will no longer be providing food and drinks, and as mentioned earlier, we will also be distributing attendee T-shirts separately in our online shop. We are still working on the details of simultaneous interpretation, but it will be provided during the conference part of Day 1.

Therefore, we have decided to reduce the ticket prices as follows

  • Online Regular Admission: 3,000 yen
  • Online Student Admission: FREE
  • Online 2nd day-only Admission: FREE
  • Online Ninja sponsorship: 15,000 yen

Online tickets are available from Doorkeeper:

scalaconfjp.doorkeeper.jp

We apologize for the inconvenience caused by this major change in the specifications for ticket holders.

Therefore, we are accepting cancellations if you wish, but please notify us by August 15 23:59 AoE (August 16 20:59 JST) using the form below. If there are no cancellations by the deadline, we will refund the difference in price.

Speaking Environment for Speakers

As communicated separately, we will be arranging the timetable according to the time zone in which the speakers live. Other confirmation and support for the online speaking environment are provided separately.

Thank you for your cooperation and response to the change in speaking arrangements.

Sponsor Benefits Modification

We have already sent out a separate notice to sponsors about how to offer benefits online.

For those sponsors who have already applied for a booth, we are taking questions, concerns, and consultations with them, especially as the specifications of the permanent booths will change significantly with the transition to virtual booths.

Lastly, I'm sure all of you reading this article have been affected by the corona outbreak in a large or small way. We would like to thank you again for your support of the event.

We look forward to seeing you all online!

ScalaMatsuri 2020 is postponed to October 17-18, 2020

This is a post written by ScalaMatsuri chair Taisuke Oe (@OE_uia), translated by Eugene (@eed3si9n).

Due to the situation of coronavirus disease COVID-19, we are postponing ScalaMatsuri 2020 to October 17th (Saturday) and 18th (Sunday), 2020. I'll go over the details and future outlook in this post.

Summary

  • The conference is postponed to October 17th (Saturday) and 18th (Sunday), 2020. Depending on the COVID-19 situation in August, we might to switch this year's edition to an online-only conference.
  • We will accept ticket refund requests until March 31st. Please submit refund request form by March 31st.
  • We are continuing to raise support from personal Ninja Sponsors and corporate sponsorship.

Details

ScalaMatsuri is an annual international conference since 2013 ran by non-profit community organizers as a matsuri (festival) of technologists who love Scala. We consider two major values for hosting ScalaMatsuri.

First is various serendipity at the venue. It provides opportunities for participants to find new technology, new finds through talks and discussions, and meet new people, open source projects, companies, and services.

Second is making chances to distribute knowledge. Speaking at the conference creates an opportunity for the speakers in and out Japan to put their thoughts into a technical presentation (ScalaMatsuri staff provides Japanese subtitles for English slides). This could become a trigger for new technical knowledge to be distributed in the Japanese Scala community, or technical knowledge exchange with the communities overseas.

As a means to efficiently realize those values, we have been renting large event spaces and hosted talks, unconferences, and hackathons as ScalaMatsuri. We think it's essential to provide these spaces for the continual growth of the Scala community worldwide.

However, due to the concern over COVID-19 outbreak, many counties and local governments are requesting to refrain from large-scale events. As a result, companies in and outside of Japan, including our sponsors, are discouraging or prohibiting their employees to attend large gatherings.

Unfortunately expert opinions do not allow for optimism in the trajectory of COVID-19 in May, when we originally scheduled ScalaMatsuri 2020. Even if we could host it in May, we expect many people won't be able to attend, and/or we'd need drastic measures to ensure the safety of participants, which would directly undermine the values we wanted to provide with ScalaMatsuri.

We have considered hosting an online-only conference. We are aware of multiple conferences that have switched to online-only at the last minute and succeeded to some degree. However, given the current ScalaMatsuri resource and our broadcasting knowledge, our call is that two-month preparation might not be enough to host an adequate online conference.

As the result, we determined that the optimum answer for participants, sponsors, speakers, and community would be to postpone ScalaMatsuri 2020 at this point. The postponed dates are October 17th (Saturday) and 18th (Sunday), 2020.

In case the COVID-19 situation does not improve by mid August we are planning to switch this year's edition to an online-only conference. We will prepare for the contingency in parallel. Therefore, we advise participants from overseas not to make travel arrangements until the August announcement.

Minimizing the effect of postponement

ScalaMatsuri is made up of participants, speakers, sponsors, and volunteer staff members who organize the event. We sincerely hope that we can minimize the effect of the conference postponement.

Ticket holders

Some of the ticket holders may not be able to make it to the postponed date. We're sorry that we'll miss you and we would accept refund requests until the end of March, 2020.

If you would like a ticket refund, please submit the refund request form by March 31, 2020. If you can attend on October dates, the ticket will carry through without further actions.

CFP applicants

We apologize for the delay in announcing the speakers. We are determining the acceptance based on the voting results and the recommendations from the selection committee.

We hope to send the acceptance notice in the next 2 weeks. We will confirm with the speaker if they can attend on October 17th and 18th, and will be accepted upon confirmation.

Corporate sponsors

We would like to extend our thanks for supporting ScalaMatsuri.

ScalaMatsuri will provide the same benefits

How to support ScalaMatsuri

We would like to extend our thanks to many who have reached out to support ScalaMatsuri. For individuals, we've created personal Ninja Sponsor; and for corporations we have sponsorships.

Ninja Sponsor

Ninja Sponsor is a sponsorship plan for individuals. You can attend the conference with Ninja Sponsor ticket, and in addition we're planning to create a small token of appreciation for your patronage.

You can apply for Ninja Sponsor from the Doorkeeper page.

It's possible to upgrade a regular ticket to a Ninja Sponsor. In that case, please use the refund request form and cancel the regular ticket.

We also welcome Ninja Sponsor from the speakers.

Future outlook

Even looking back to 8 years of organizing ScalaMatsuri, this is a highly unusual situation that we have never experienced. There remains various uncertainties, and (although we have evaded critical hits) the budgetary burden too is higher than usual.

On the other hand, we stand in a rare situation where we are given extra time to prepare for the conference after the heavy lifting of CFP is over. We hope to use this to improve the conference and to energize the local Scala community.

In particular, in addition to the regular ScalaMatsuri 2020 conference preparation we are planning the following actions:

  • Preparation for online-only conference by October.
  • Planning and organization of a smaller online subevent before October.
  • Call for additional lightning talk speakers.

How to contact us

ScalaMatsuri organizer is available to discuss any questions and concerns by the following contact form.

Summary

ScalaMatsuri 2020 will be postponed to October 17th (Saturday) and 18th (Sunday), 2020. Depending on the COVID-19 situation in mid August, we might switch to an online-only conference, so we advise participants from overseas not to make travel arrangements yet.

We will accept ticket refunds until the end of March. We hope to send out CFP notices in 2 weeks.

Individual Ninja sponsorship and corporate sponsorship are welcome.

Stay healthy, and thanks for your continued support of ScalaMatsuri!

Save the dates for ScalaMatsuri 2020!

ScalaMatsuri is the largest Scala event in Asia. We're excited to announce the dates ScalaMatsuri 2020 dates to be May 15th (Fri) and 16th (Sat)!

ScalaMatsuri 2020 | The largest international Scala conference in Asia

We are increasing the number of tracks to four tracks on the day 1 to total of 4 tracks. With the increased track, we are hoping to accept more talks geared towards Scala beginners.

On May 16 (Sat), we plan to have some conference track, "unconference" track that determines the talks on the day of, and the annual open source hackathon.

The beginner workshop was well received in the last conference. As a new experiment, we are thinking about hosting beginner workshops throughout the year, instead of a one-time workshop during ScalaMatsuri. The details will be announced at a later date.

CFP is now open!

Come speak at the largest Scala event in Asia with over 600 attendees.

  • Great way to promote your current project.
  • Spread your favorite technique.
  • Let the world know your skill set beyond your work circle.
  • Discuss with other participants and speakers.
  • Socialize with other experts at the speaker dinner.

Personally speaking, becoming a speaker is one of the best ways to enjoy a conference. If you're on the fence, please submit your talk.

Session category

Any topic that might be of interest to Scala learners and Scala community members are welcome. As a reference, take a look at last year's schedule for the accepted talks.

ScalaMatsuri 2019 | The largest international Scala conference in Asia

For this year, we've created a new category called "Scala beginners", but due to the fact that the two-way interpreters are available in two main halls only, we will not accept English talks ONLY for the new "Scala beginner" category. However, we welcome foundational talks explaining some concept from the basics, which can be also relevant for Scala beginners.

Other details

For this year, we will have 40 min sessions and 100 min sessions (of which 20 min are recess). Feel free to submit lecture style talks or workshops.

The talks are determined by both the program committee and voting by participants.

ScalaMatsuri wants diverse speakers from all over the world. To help break down the barriers, we're excited to offer travel grant ranging from USD 500 to 1500, depending of whether you're a student and the point of origin. Please see the following page for more details:

Session voting begins!

Hi. This is @eed3si9n, one of many ScalaMatsuri organizers.

Summary

tl; dr. Here are the gist of this post.

  • The voting will be conducted by ticket holders, sponsors, and staff. It will close at Monday, December 25st, 23:59 JST.
  • The voting results will be interpreted more like a public opinion poll. In that, instead of picking the speakers purely based on the number of votes, ScalaMatsuri selection committee will pick up the mix of popular sessions, sessions with the most buzz on social networks, as well as hand-picked sessions.
  • The voting UI will be available directly from the ScalaMatsuri website after logging in.

A regional tech conference that's also global

ScalaMatsuri 2018 will continue to uphold the two major goals in a sustainable way:

  • Providing a space for Japanese Scala community to socialize, and present ideas to the international audience.
  • Make a global technical conference with the universal access, where people from various background such as languages, gender, or ethnicity, can be comfortable.

The concrete actions taken for these goals are documented in my last year’s post A regional tech conference that's also global, but here are the hightlights:

  • Establishing Code of Conduct, and making an intro video for it.
  • Public CFP, travel grant, and translations of the submitted session abstracts.
  • Public voting of the sessions.
  • Subtitles on the slide decks and professional two-way interpretation.

My thoughts on how these went are written up in ScalaMatsuri as a lifestyle.

Uncategorized voting

To research “what the audience wants to see on the day of the conference,” ScalaMatsuri 2018 will adopt uncategorized voting. In other words, we will remove the categorization of English/Japanese 90/40/15 minutes, and you can pick whatever you want to see from all the proposals. One of the reasons we are even able to consider this, is because we have successfully implemented two-way interpretation. We no longer have to be nervous about the language barrier issue.

Public opinion poll

One point I want to clarify before we begin the voting this year, is that this year’s voting will be considered a public opinion poll.

In 2016 we observed that when hundreds of people try to select 22 sessions, the selected talks end up forming a cluster of similar topics. This is actually an obvious outcome because the voters did not talk to each other to coordinate “hey, let’s pick that talk for intro to fp.”

Instead of picking talks from the top mathematically, we think the conference would be far more enjoyable if we treated the voting more like a public opinion poll to infer topics and trends. ScalaMatsuri selection committee will pick up the mix of popular sessions, popular topics, as well as hand-picked sessions with some degree of subjectiveness.

SNS impact

As an additional data point to measure popularity and the trend, we will take SNS impact into the account. The SNS impact will be calculated by quantifying the buzz (or share) on Twitter, Facebook, Hatena Bookmark etc to measure the excitement about the session.

We are planning to tally the number of times a session was shared to Twitter, Facebook, and Hatena Bookmark via the social buttons placed on each proposal page of the official ScalaMatsuri website.

Voting program

We will continue with the voting program made by Tech to Value. After logging in, you can now vote from the ScalaMatsuri website’s session proposal list.

ScalaMatsuri 2018 CFP is now open!

Hi, ScalaMatsuri organizer Kasuya (id:daiksy) here.

We are excited to announce that the fifth ScalaMatsuri will be held on March 16th (Fri), 17th (Sat), and 18th (Sun), 2018 at Tokyo International Exchange Center. Please submit your talk for the general sessions that will be held on 17th (Sat) or 18th (Sun).

f:id:daiksy:20170225100008j:plain
Nakamura-san, who got voted the most last year

Here are the overview of the CFP:

  • CFP will close at December 16th 23:59 JST.
  • We are looking for topics that you think Scala community or new learners of Scala would be interested.
  • Session length: 10, 40, or 90 minutes.
  • You are allowed up to three submissions.
    • We'll ask you to select one talk even if multiple talks qualify.
  • Speakers will be decided using survey and SNS impact as references.
  • For those who request it, we have fixed-amount travel grants for speakers with most votes.
  • We require all participants to respect our Code of Conduct
  • See http://2018.scalamatsuri.org/en/cfp for more details.

Your talks make ScalaMatsuri a great event every year. Let's do this again for 2018!!

Here are some more details.

Session lengths

We've created 10, 40, and 90 minute sessions. Pick the length that fits your content the best -- from lighter talk to more involved lectures.

The new addition this year is the 90 minute length. This is intended to cover workshop and other formats different from lecture-style sessions that would have been difficult with the conventional 40 minute session. Conventionally these were covered by the Unconference, but we can now plan ahead for these types of sessions.

Of course, if you would have something to lecture using the whole 90 minutes, that is welcome as well. Surprise us with your new ideas.

SNS impact

Speakers will be decided by a selection committee using participant's voting as the primary reference, but we will take SNS impact into the account. The SNS impact will be calculated by quantifying the buzz (or share) on Twitter, Facebook, Hatena Bookmark etc to measure the excitement about the session.

We are planning to tally the number of times a session was shared to Twitter, Facebook, and Hatena Bookmark via the social buttons placed on each proposal page of the official ScalaMatsuri website.

This is intended to create buzz around ScalaMatsuri up front, and also to attract people to your proposals. Once your proposals get on the official ScalaMatsuri website, please share it on various media to advertise your proposal.

Travel grant

ScalaMatsuri wants diverse speakers from all over the world. To help break down the barriers, we're excited to offer travel grant.

Here are the only categories that can assist (because we are a non-profit):

  1. Airfare and other transportation to Tokyo.
  2. Other transportation during ScalaMatsuri
  3. Hotel fares during ScalaMatsuri general sessions. (three nights for March 16th, 17th, and 18th)

Any other expenses, including ones incurred from sightseeing or hotel fares (priced per person in Japan) for accompanying travellers, cannot be expensed by us. Please note that we expect hotel fees to be covered either by the speakers or from the travel grant. In other words, you must book the hotel and air travel on yourself.

The maximum amount of the travel grant is fixed by the origin of your travel:
