[A guest post by PyCon ;s Open Spaces Chair, Anna Ossowski!]
Open Spaces are one of the most often overlooked activities at the PyCon conference.
PyCon is not merely a 5-track conference — it’s true there are 5 tracks of talks, but there are also 5 tracks of Open Spaces that run alongside the talks.
What are Open Spaces?
Open Spaces are self-organizing meetup-like events which occur in parallel with main conference talks. There are actually more hours of Open Spaces, in total, than there are of talks! While most of the conference is planned months in advance, Open Spaces are created on-site by PyCon attendees. They offer groups the ability to self-gather, self-define, and self-organize in a way that often doesn’t happen anywhere else at PyCon.
Open Spaces are one-hour meetups during the three main conference days, held in meeting rooms within the PyCon convention center. Some people reserve spaces to discuss a favorite technology — like web frameworks, neural nets, or natural language processing — while other people focus an open space on an interest like astronomy, data science, teaching. Other attendees schedule actual activities during Open Spaces, like yoga, nail painting, and board games! Attendees can discover these events via the Open Spaces board which will be next to the registration desk.
Any topic or activity that two or more attendees are interested in could be a good candidate for an Open Space. You can find a list of sample ideas a few pages down in the Open Spaces guide on our web site:
If you have additional ideas, please email us at
and we can add them to the list.
An extra day to plan each Open Space!
Like last year, each day will feature two Open Space sign-up boards near the registration area: one for the current day, and one board that is already up for the following day.
This will allow hosts to reserve a slot a full day in advance — creating a longer window for them to advertise the space to interested attendees. And attendees will be able to go ahead and start planning which Open Spaces they want to attend the next day.
In fact, the first Open Spaces board will be up on Thursday evening during the Opening Reception, the evening before the main conference even starts! This will give hosts a chance to reserve a slot for the first day of the conference while it is still the night before.
Promote Your Open Space
We are using the hashtag #PyConOpenSpace again this year. We encourage you to use this hashtag to promote your Open Space. It’s also a great idea to add your Twitter handle to the card that you pin on the Open Space schedule board, in case anyone interested in attending your open space has a question or wants to contact you about it.
The committee is looking forward to all of the great Open Spaces that are awaiting us at PyCon US 2017!
(A guest post from Jason D. Rowley, one of ;s Startup Row Coordinators!)
What could be more exciting than startups who use Python and are poised to change industries and help build the future?
We are very pleased to announce the seventh batch of companies that get to present on Startup Row. Come and visit Startup Row in PyCon 2017's Expo Hall to see some of the most interesting and innovative new technologies and business models out there, and to hear the engineers and other founders of these leading early-stage companies pitch their ideas and discuss how and why they use Python.
And without further ado, here they are — PyCon ;s Startup Row batch:

In Seattle, we’d like to thank our hosts at Avvo: LaQuita Hester, Kalin Woo, and Eileen Kim. The Seattle event fielded a slate of six women founders competing for a spot at PyCon.
In San Francisco, we owe many thanks to our generous hosts at Yelp, and to Grace Law, Simeon Franklin, Daniel Pyrathon and the rest of the SF Python community for hosting Startup Row. Thanks to our judges: Lisa Dusseault, Bebe Chueh, Christine Spang, and Elliott Kroo for joining us. And to Shea Tate Di-Donna, thank you for MC’ing the event.
We’d also like to thank the Python Software Foundation, specifically the support and encouragement we’ve received from Ewa Jodlowska and Brandon Rhodes throughout this season. We also want to acknowledge the Startup Row selection committee who helped select from among the companies that applied through our online application. Finally, we would like to thank Yannick Gingras, the emeritus co-chair of Startup Row, who continues to provide advice and support while on hiatus from active organizing.
Again, to all those who help make Startup Row happen, we thank you and appreciate your support.
Finally, to all the founders who pitched at our live events or applied online, we were impressed by the creative and interesting ways everyone uses Python to build great software and scalable businesses. This was one of the strongest applicant pools yet, and we’d love to see qualifying companies apply again next year for a second shot.
We wish all of you the best of luck — and to those companies on Startup Row, we’ll see you in Portland!
It’s back.
Thanks to generous sponsorship from ,
we are excited to announce
that PyCon 2017 will feature the return of the legendary Testing BOF!
If you want to attend,
all that’s necessary is to sign up for free on Eventbrite (the link is below)
and then be sure to be at McMenamins Crystal Ballroom
at 9:30pm on Friday evening —
the first night of the main three PyCon 2017 conference days.
From 9:30pm&#pm that Friday night,
McMenamins Crystal Ballroom will be sparkling
with the wit and technical wisdom
of quick talks covering Python, testing, and the terrain in between
at this high-velocity lightning-talk-style event.
This popular birds-of-a-feather (BOF) session
provides a late evening of lightning talks and socializing
for those who write tests, maintain testing frameworks,
complain about testing frameworks, or who are simply testing-curious.
This is an official PyCon event
and is governed by our
Thanks to Heroku, drink tickets and snacks will both be provided!
Attendees will need a conference badge and an Eventbrite registration
to enter the event.
If you are interested
and will be able to make it across town to the Ballroom on Friday night,
then simply
and we will hold a spot for you!
Again, please plan ahead, since McMenamins Crystal Ballroom is across downtown Portland from the main PyCon venue. The ballroom’s address is
about 8 minutes by car or 22 minutes by light rail from the Portland Convention Center where PyCon itself is held. You will probably want to wrap up your day at the Convention Center, head somewhere across the river for a quick dinner, then aim to be at the Ballroom by 9:30pm.
We again want to thank Heroku,
and we hope that the return of this BOF
will spur the development of even more of the sort of tools, techniques,
and practices that will make Python software
renowned across the world for being dependable and robust.
Obey the goat — attend the BOF!
We are happy to announce PyCon ;s Sunday morning plenary event —
the final day of this year’s main conference
will feature Guido van Rossum on a panel of Python programmers
who attended the first-ever Python conference back in 1994!
Paul Everitt will moderate the panel
as they answer questions and share their memories
about that first Python conference
when the programming language was still young.
At the beginning of 1994,
the World Wide Web consisted of less than 1,000 sites.
There was no distributed version control.
No public issue trackers.
Programmers communicated their ideas, issues, and patches
in plain text on mailing lists and Usenet newsgroups.
The small community of Python programmers
were connected through both a mailing list
and the comp.lang.python newsgroup,
which was busy enough that several new messages were appearing each day.
An exciting announcement
blazed out to subscribers of the Python mailing list
in September 1994:
Guido van Rossum,
the Dutch researcher who had invented Python,
was going to visit the United States!
An impromptu Python workshop was quickly organized
for the beginning of November
where Python programmers could for the first time
meet each other in person.
Attendees of the first Python conference,
in a tiny and highly artifacted JPEG
that was typical of the era
Of the small group who gathered at NIST over November 1&#94,
several will be on stage
to share about both the triumphs and the mistakes of those early years.
The panel is currently slated to include:
Guido van Rossum
Paul Everitt (moderator)
Barry Warsaw
Jim Fulton
There is one way that you in the Python community
can go ahead and start helping us prepare for the panel:
We need your questions!
You can go ahead and suggest questions
by tweeting them with a hashtag of #nist1994.
The panel will curate your tweeted questions
along with questions that they solicit elsewhere,
and will have their favorites ready for the panel at PyCon.
Thanks to Paul Everitt for organizing the panel,
which will aim to spur not only nostaligia for a lost era
but lessons, warnings, and inspirations for future generations
of Python developers!
Only one month from today, PyCon will be almost over! The conference will be on the third and final day of its program. The sponsor booths will all have been packed up the night before and the Expo Hall re-purposed for a morning full of
tables. Only one quick afternoon of talks will stand between us and the closing ceremonies.
Here in the present, the hatches are nearly all battened down. The schedule is set. The conference is completely sold out of registrations. The sponsor lineup is nearly finished, with only a few booths still left to be claimed. Almost everything is now in place — though, we do still , a topic about which we will blog in further detail next week.
Meanwhile, the time has come to announce this year’s keynote speakers, who will be addressing the conference during our plenary sessions! They are:
Kelsey Hightower
Jake Vanderplas
Lisa Guo & Hui Ding
We look forward to hearing from each of them!
You might be wondering: where on this list is Python’s fearless leader and perpetual keynote favorite, ? Don’t worry! Guido will definitely be on stage this year as part of a special Sunday morning plenary session — the details of which we will be announcing soon. Intrigued? Watch for our announcement next week!

It seems hard to believe,
but two months from today
PyCon 2017 will be underway in Portland!
Attendees will be enjoying a full day of scheduled talks,
self-organized Open Spaces,
and visits to our many sponsors the Expo Hall.
Only a little more than eight weeks remain
until we meet in Portland.
As PyCon’s volunteers
put the finishing touches on their plans, talk slides, and rosters,
here are several updates on the conference:
Less than 100 tickets now remain!
Soon the conference will be sold out
and unable to accommodate any further attendees.
If attending is crucial for you,
we recommend signing up immediately while there is still time.
All the major schedules are available on the site.
The program committees who select
have completed their hard work for the year —
thank you, volunteers! —
and you can already start planning what you want to see.

Attendees can register for free for these sessions
that give sponsors the chance to offer technical content,
in-person instruction, and short talks to community members
interested in their techology.

has grown and grown
until, at least in my browser, it now takes
nearly 40 PgDn keystrokes to reach the bottom!
We are thrilled that so many organizations,
both for-profit and non-profit,
are finding it worthwhile to come alongside
the open-source Python community
and support the idea of a free programming language.
We are excited about this year’s conference.
We know, of course, that only a fraction of the world’s Python community
ever gets to attend any individual PyCon,
and so we will be recording and preserving as much as possible
for the use of all of the world’s programmers for years to come.
But for those who will be able to manage the travel and to attend,
we look forward to your presence in Portland
and wish you well as your preparations
enter their final weeks!
The deadline for applying to PyCon 2017 for Financial Aid
is this coming Wednesday, February 15th!
The link to the application is on our main Financial Aid page:
Given that international travel to the United States
has become a greater risk for many in the international community,
PyCon wants to make an extra stipulation this year
to try to protect our Financial Aid recipients
in case they are turned away upon arrival in the United States.
But, first, let’s get clear
about the risks and duties of those who are awarded Financial Aid.
For many people,
airline tickets and nights at a hotel are never routine expenses.
They are frightening blows against a bank account —
large, exceptional purchases for special occasions.
But what if a person becomes too ill to travel,
cannot get a full refund,
and the money is simply lost?
What if a missed flight adds hundreds of dollars of extra expense
that were not in the budget and for which they are unprepared?
While PyCon’s Financial Aid program
does strive to make travel possible
for a broader audience
than could comfortably attend the conference on their own budget,
it cannot eliminate the risks of travel.
Indeed, its mechanism for delivering awarded funds —
a physical check that must be collected at the conference itself —
can only succeed for travelers who actually reach PyCon.
So let’s review the risks of traveling to PyCon
in the hope of receiving a Financial Aid check,
and then learn about
the new promise that the conference is making this year:
Financial Aid is designed to help with travel expenses, not with your visa application fee. Financial Aid applicants have always been responsible for paying their own visa application fee, whether the visa is granted or denied. This remains true for PyCon 2017. So keep in mind that if your visa is denied, the United States will not refund your processing fee, and — as you will not be traveling — PyCon will not be giving you Financial Aid or refund your visa processing fee.
You should apply for your visa, if you decided to attend, right after you receive our response to your Financial Aid application.
As you start the visa application process, go ahead and register for the conference. You can do so without risk: we always fully refund a registration fee when a visa application is denied. We even waive our usual $25 fee for processing a cancellation — you receive back the full registration fee that you paid!
However, we advise you to delay any non-refundable travel purchases until after you have been granted a visa. Many applicants wait until they have their visa in hand before they even book a hotel room, and almost everyone waits until the visa arrives before purchasing airfare.
Beyond those guidelines, we have traditionally provided only the promise that each Financial Aid recipient, if they make it to PyCon, will receive their check. This obviously burdens each applicant with a risk: that if their travel plans go awry and they cannot reach Portland, that they will receive no Financial Aid. They will have to try cancelling their hotel room in time to receive a refund, and ask their airline if any kind of a refund is possible.
In previous years, PyCon assumed this risk to be a reasonable one.
But we want to make a new stipulation here in 2017. First, if despite holding a visa you are denied entry upon arrival to the United States, then after you pursue and receive whatever refund your airline might be able to offer, PyCon wants to send you enough of your Financial Aid grant to cover the rest of the cost of your airfare (or the whole grant, if the airfare cost more). You will need to document that you indeed arrived in the United States and were denied entry.
Second: if despite holding a visa you are denied entry upon arrival to the United States, but used our registration page to book a room in a conference hotel, our staff will personally work with the hotel to make sure you do not receive a cancellation fee.
Third: if despite holding a visa you are denied entry upon arrival to the United States, PyCon will fully refund your registration fee. While this is more serious for our conference budget — at such a late date, we will be unlikely to be able to register someone else in your place — we have decided to put the financial safety of our Financial Aid recipients from overseas first.
We hope that these extra guarantees
beyond the normal terms of our Financial Aid program
will help applicants plan more confidently
and will continue to make PyCon 2017 an option
for as wide a slice of the worldwide Python community as possible.
