Signature project

Top ten Bluebike stations in Boston: three ways to get it wrong

Analyze Boston publishes the Bluebike station list under a public domain dedication, updated nightly. We downloaded it on 18 October 2026: 572 stations across 13 municipalities, 324 of them in Boston itself.

Boston stations with the most docks (our ranking of the Analyze Boston Blue Bike Stations data, District = Boston, 18 October 2026)
Rank	Station	Docks
1	South Station	47
2	Forest Hills	40
3	A station on Nashua Street	37
4 and 5 (tied)	Two stations	35
6 and 7 (tied)	Two stations, one at Copley Square	33
8 to 10 (tied)	Three stations, including a second Nashua Street record tagged Extension	32
Next	Three more stations	31

Mistake 1: sorting text

The dock column is stored as text. Sort all 572 stations as strings and the top two are both Salem stations with 9 docks, because the character 9 beats the character 5 in 53. Converting to integers first fixes it.

Mistake 2: ignoring ties

Ten places end exactly on a three-way tie at 32 docks. Ask for the top eight instead and you must cut a tie in half; the honest answer lists all three or says how the tie was broken.

Mistake 3: duplicate places

One location shows up twice, the second record tagged [Extension]. Is that one big station or two? The ranking changes depending on the answer, so a student has to decide and say so.

In pandas the correct version is short: df["Total_docks"].astype(int), a filter to District == "Boston", then nlargest(10, "Total_docks", keep="all") so ties are kept rather than dropped. Students then explain in writing why their list has the length it does.

The shape of the Boston dock counts (our figures)
Measure	Value
Stations in Boston	324
Docks across those stations (our sum)	5,945
Median docks per station	19
Stations with exactly 15 docks	106
Stations with exactly 19 docks	100

Our ranking, the city’s data

The ranks, sums and medians here are our own, from one download on 18 October 2026. Dock counts change as stations are added or resized, and the data does not say how many bikes are present at any moment. A top ten is only as true as the day it was taken, which is why we print the date with it.

Ranking to AI

Why a ranking is the first lesson in machine learning

Recommendation systems, search engines and model leaderboards are all top-N lists underneath.

Search and feeds

Every feed a teen scrolls is a ranked list. Knowing how ties, duplicates and sort order work shows how fragile those rankings can be.

Model scores

When students compare models, they rank them by a score. A gap of one point can be noise, just as two stations with 33 docks are equal.

Fair comparison

Ranking Boston stations against Cambridge ones mixes two cities with different layouts. Choosing the right comparison group comes before any algorithm.

Our project sequence for Boston teens
Week	Task	Skill
1	Load the station list, count rows per municipality	Reading data, grouping
2	Build the Boston top ten correctly, with ties	Type conversion, sorting
3	Decide what to do with duplicate locations	Data judgment, documentation
4	Predict a station’s dock count from its neighbours	A first regression model and its error

The fourth week is where AI begins. A student trains a simple model, then discovers it predicts 15 or 19 most of the time, because those values dominate the data. That is a lesson in class imbalance that no tutorial video teaches as well as one surprising result.

Boston facts we used

Boston, Massachusetts, in the city’s own figures

Official City of Boston pages, read on 18 October 2026.

What the City of Boston publishes
Topic	Figure	Source
City Council	The 13 councilors: four at-large and nine district councilors, elected every two years	City of Boston, City Council
Park land	more than 2,200 acres of park land	Boston Parks and Recreation
Urban wilds	31 urban wilds	Boston Parks and Recreation
Golf	2 public golf courses	Boston Parks and Recreation
Street trees	more than 45,000 public street trees	Boston Parks and Recreation
Community centers and pools	36 facilities across Boston	Boston Centers for Youth and Families (BCYF)
Bike share	324 Bluebike stations within Boston (our count)	Analyze Boston, Blue Bike Stations

All 572 stations in the file are marked public, and Boston has more than three times as many as Cambridge, the next municipality on the list with 92. Counting by municipality before ranking is the habit that stops a teen from comparing the wrong things.

Massachusetts schools

Finding computer science course data for a Boston school

One practical pointer from the state, not a summary of the rules.

The Massachusetts Department of Elementary and Secondary Education (DESE) publishes a Digital Literacy and Computer Science Course Taking Dashboard that, in DESE’s words, “displays data about K-12 students completing at least one Digital Literacy or Computer Science (DLCS) course in a given school or district.” A Boston family can use it to see how computer science is taken in their own district. DESE has also reviewed curricula against its DLCS framework and marks each as core or supplemental for a grade span. Statewide, Code.org’s 2025 data places Massachusetts high schools offering computer science at 81.25% in 2023 to 2024 (Code.org (2025). 2025 State of AI + CS Education).

Reading the dashboard

The dashboard is itself a dataset. A teen who can filter it to one district and compare years is practising the same skills as the Bluebike project.

School first

If a Boston school offers computer science, take it. Our classes work alongside it with projects, AP preparation and AI depth.

Graded work

We teach concepts and methods. Anything a school grades is written by the student alone.

Class times

Eastern Time and a Boston school week

Boston keeps America/New_York in the IANA time zone database. Our teachers are in India.

You set the slot

Weekdays or weekends, flexible: choose your batch, or for a very personalised plan choose 1-on-1 at your convenience, weekend mornings or weekdays.

The India gap

India runs 9 hours 30 minutes ahead of Boston in summer and 10 hours 30 minutes ahead in winter, so a Boston evening class is an early India morning.

Two dates this year

Standard time returns on November 1, 2026 and daylight time on March 14, 2027. Our confirmations always give the Boston time.

Sorting times is sorting text too

A teen who stored class times as strings like 9:00 and 10:00 finds that 10:00 sorts first. It is Mistake 1 from the Bluebike project again, in a new costume, and the fix is the same: convert before you sort.

Building AI

Can a Boston teen skip Python and go straight to AI tools?

They can use tools without Python. They cannot judge them.

Ask an AI assistant for Boston’s top ten Bluebike stations and it may sort the text column, drop a tied station or count the Extension record twice, and present the result with total confidence. A teen who has made those mistakes by hand will spot them at once.

We teach the code first because it gives students a way to check. Once they can, AI assistants speed up their work instead of replacing their thinking. Teens also learn to respect the minimum ages AI providers set in their own terms.

Our AI courses start with rankings, tables and mistakes, and move to models only when a student can explain every step behind the score. The longer argument is in is coding still worth learning in 2026.

Delivery

Dorchester to Brighton, the same live class

Boston neighborhoods are close on a map and slow in traffic. An online class is no distance at all.

Join from home

A teen logs in from their own room anywhere in Boston, so winter weather and the commute never cancel a lesson.

Planned in US grades

Lessons follow US grade levels and the Massachusetts school year, with extra support before AP exams.

Free trial class

A real Python task with a teacher, then a suggested course, level and time. Card details are never requested at this stage.

Same-stage batches

A group of fifteen to twenty teens who are all at one point in the course, from Boston and the rest of the US.

Private teaching

One teen with one teacher, for AP preparation or a faster pace in AI.

Eastern Time

Weekdays or weekends as you choose, confirmed in Eastern Time.

Online, not local

We have no Boston office and claim none. Teaching is live online from India, and we are not connected with the City of Boston, Bluebikes, DESE or Code.org.

FAQ

Boston teen Python and AI questions

Short answers for families in Boston, Massachusetts.

Is this page for Boston, Massachusetts?

Yes. It is written for families in Boston, Massachusetts, uses data from Analyze Boston, and schedules classes in Eastern Time.

What is the Bluebike ranking project?

Teens download the Blue Bike Stations list from Analyze Boston, convert the dock column to numbers, rank the Boston stations, and handle ties and a duplicate record correctly.

Why does sorting the dock column go wrong?

The column is stored as text, so 9 sorts above 53. Converting the values to integers before sorting gives the right order.

Are the station rankings official?

No. They are our own ranking from a download on 18 October 2026, and dock counts change over time.

Does my teen need Python before AI?

Yes. Python and data handling come first, because judging any AI result depends on being able to check the data and code behind it.

How can I see computer science course data for my Boston school district?

DESE publishes a Digital Literacy and Computer Science Course Taking Dashboard showing K-12 students completing at least one such course by school or district.

When are classes for Boston teens?

Weekdays or weekends, flexible: choose your batch, or for a very personalised plan choose 1-on-1 at your convenience, weekend mornings or weekdays. Times are confirmed in Eastern Time.

How big are the groups?

Fifteen to twenty teens at the same level, or a private class with one teacher.

Do you have a Boston location?

No. Every class is live and online, taught from India.

Where can I find the prices?

In the fees block on this page: a free trial class, then a monthly group plan or a monthly private plan. You pay nothing before the trial.
