Coding classes in Diemen, where a metro and two railways meet

What are the best coding classes in Diemen?

Diemen had 33,327 residents on 1 January 2026, the national statistics record. First mentioned in 1033, it grew from the middle of the twentieth century as a commuter town for Amsterdam, and it has stayed an independent municipality, squeezed between Watergraafsmeer, Duivendrecht and Amsterdam-Zuidoost. Its connections tell the story: a station on the Gooilijn since 1974, and since 1993 a railway station on the Ringspoorbaan beside the metro at Diemen-Zuid. A set of stations joined by lines is what programmers call a graph, and finding the fastest way across it is one of the classic problems of computing, solved by the algorithm every route planner still uses. The fastest route, it turns out, is often not the one with the fewest stops. Modern Age Coders teaches live online in English for ages 6 to 67; the first lesson is free, then USD 100 a month in a group or USD 150 one to one.

Look at a travel map around Diemen and it is a web of dots and lines: the station on the Gooilijn, the metro and the railway meeting at Diemen-Zuid, the roads to Amsterdam, Weesp and beyond. Computer scientists call such a web a graph, with the dots as nodes and the lines as edges, and each edge carries a cost, such as minutes, kilometres or money. The question a route planner answers, what is the cheapest way from here to there, was solved in general by Edsger Dijkstra, whose method, published in 1959, still sits inside navigation apps, internet routing and many AI planning systems. It works by always extending the cheapest route found so far, and it guarantees the best answer. Its lessons are useful far beyond travel: the obvious route is not always the best, the best route depends on what you choose to count as cost, and a network full of shortcuts can make a route with more stops the fastest of all.

Diemen today

A settlement of 1033, a commuter town, and a town that stayed its own

The encyclopaedia divides Diemen into six parts, Diemen-Noord, Oud-Diemen, Diemen-Centrum, once called Diemerbrug, Diemen-Zuid, Diemen Sniep and the outlying area; the statistics office counts nine wijken, including Plantage de Sniep, Holland Park and Bergwijkpark, and 38 buurten. On 1,195 hectares of land and 209 of water it has a published density of 2,781 residents per square kilometre.

Its own municipality

Diemen has held on as an independent municipality, squeezed between Amsterdam-Watergraafsmeer, Duivendrecht and Amsterdam-Zuidoost, the encyclopaedia says.

Green in the middle

Park Spoorzicht is a nature park in the centre of Diemen, and the Diemerbos, planted between 1992 and 1996, is one of the youngest woods in the region.

A young population

Of the 33,327 residents counted for 2026, 11,110 are aged twenty-five to forty-five, a third of the total, and institutions in the municipality count 1,890 university students.

The fastest way across

Five stops, seven connections, and a surprising answer

The network below is invented to show the method, not a real map of Diemen. Travel times between stops, in minutes: A to B 4, A to C 10, B to C 3, B to D 12, C to D 5, C to E 11, D to E 2.

Dijkstra's method from A, fixing one stop at a time
StepStop fixedFastest time from AReached via
1A0 minutesthe start
2B4 minutesA
3C7 minutesA, B (not the direct 10)
4D12 minutesA, B, C (not B to D, which gives 16)
5E14 minutesA, B, C, D

The fastest route from A to E takes 14 minutes and passes through every stop. The two-stop route, A to C to E, takes 21 minutes, and A to B to D to E takes 18. A traveller who counted stops would choose badly; a program that counts minutes chooses well. Dijkstra's method gets there by a simple rule repeated: of all the stops not yet fixed, fix the one that can be reached soonest, then see whether going through it improves the time to its neighbours. When the destination is fixed, its time is guaranteed to be the best possible, provided no connection has a negative cost. Change what counts as cost, say to money, or to the number of changes between metro and train, and the same method finds a different best route. Choosing the cost is the human decision; finding the route is the computer's job.

Verified local facts

Diemen in the national statistics

The figures published for the municipality with their years, the encyclopaedia history, and the page's own arithmetic at the end.

Residents

23,078 in 1995, 25,218 in 2013, 33,228 in 2025 and 33,327 on 1 January 2026. The 2025 count is 16,212 men and 17,016 women.

Ages in 2026

4,794 under fifteen, 4,872 aged fifteen to twenty-five, 11,110 aged twenty-five to forty-five, 7,092 aged forty-five to sixty-five, and 5,459 aged sixty-five and over.

Households

16,881 households in 2025, averaging 1.95 people: 7,857 of a single person and 9,024 of more, 4,798 of them with children.

Homes and income

16,115 dwellings in 2025, 6,446 owner-occupied and 9,669 rented, with an estimated average value of 460,000 euro. Average income was 38,300 euro per resident and 46,800 per income recipient in 2024, and 5.1 percent of residents were in poverty.

Schools and origin

7 primary establishments teach 2,423 pupils and there is one secondary establishment; institutions in the municipality count 527 MBO, 830 higher professional and 1,890 university students. By origin, 45 percent of residents are Dutch, 17 percent European and 38 percent from outside Europe; 65 percent were born in the Netherlands.

The arithmetic

33,327 minus 25,218 is 8,109, a rise of 32 percent since 2013. The age groups, the men and women and the household types were added up to confirm their totals, and the tenure groups make 16,115. The network example uses invented times only.

Modern Age Coders has no connection with the municipality of Diemen, the railway or metro operators, or any school in the area, and nothing on this page implies one. The statistics are those published for Diemen for the years stated. The oldest mention, the growth, the six parts, the stations, the Diemerbos, Park Spoorzicht and Diemen's independence come from the encyclopaedia entry for Diemen, which gives 33,284 residents on 1 January 2026 and 14.04 square kilometres, from a different source, not combined with the statistics.

Signature project

Draw the network, then let the computer find the way

Graphs are one of the most useful ideas in computing, and a learner can go from a drawing on paper to a working route finder in a few lessons.

1. Draw it as a graph

Put the places as dots and the connections as lines, and write a cost on every line. The drawing is already the data structure a program needs: a list of nodes and a list of weighted edges.

2. Run the method by hand

Work through Dijkstra's rule on paper, fixing the nearest unfixed stop each time. Doing it once by hand makes the code obvious, and shows why it always finds the best route.

3. Change the cost

Swap minutes for money, or add a penalty for each change of line, and run it again. The best route changes, which shows that the question you ask decides the answer you get.

Why AI still needs the classic algorithms

Ask an AI assistant for the best route through a network and it will usually give a sensible-sounding answer, based on patterns in text it has read. That is not the same as solving the problem. A language model does not run Dijkstra's method in its head; it predicts what a good answer looks like, and on a network it has never seen it can confidently choose a route that is slower, longer or simply impossible. The reliable approach combines the two: let the AI help describe the problem, choose sensible costs and write the code, and let the proven algorithm find the route. Many AI systems now do exactly this, calling a real route-finding tool rather than guessing. The same goes for scheduling, logistics and any task that is secretly a graph. A learner who has worked the method by hand on five stops, and seen the longest-looking route win, understands why a guaranteed algorithm is worth more than a confident guess. Diemen, a town defined by where its lines meet, is a good place to learn it.

For younger learners

A maze drawn on squared paper and then built as a game. The child finds the way by hand, then watches the computer find the shortest path and compares the two.

For teenagers

Dijkstra's method in Python on a small network the teenager draws, then on a real public transport map exported from open data, with two different choices of cost.

For adults

A work problem, delivery rounds or meeting rooms or task order, drawn as a graph. Adults often find it becomes solvable the moment it is drawn.

This section uses the encyclopaedia's account of Diemen's stations as its setting and an invented network for the worked example. It gives no real travel times for any Diemen connection.

Learning ladder

From a maze on squared paper to route finding with real data

Each learner's starting level comes from the free lesson, by watching them on a real task. Age alone does not decide it, and neither does the part of Diemen they live in.

Coding and AI

An AI can suggest a route in a second. Why should a teenager in Diemen learn how the best route is really found?

Because a confident guess about a network is not the same as a guaranteed answer.

Language models are very good at describing routes, schedules and plans in fluent sentences, and less good at actually optimising them. Given a network of stops and times, a model may pick the route that looks natural, often the one with fewest changes, without checking whether another is faster. It sounds certain either way. That matters for anything from travel to deliveries to the order in which tasks should be done, all of which are graph problems underneath.

A learner who has worked Dijkstra's method by hand on five stops, watched the route through every stop beat the direct-looking one, and then coded it, knows the difference between an answer that sounds right and one that is proven right. Recognising that a problem is a network, choosing what to minimise and insisting that a real algorithm does the solving are human decisions. The model can describe the journey. Making sure it is the best journey is the person's job.

So the case for a child in Diemen learning to code in 2026 is not the metro or the railway. It is that someone who can turn a messy problem into a graph and solve it properly will be needed wherever AI is asked to plan routes, rounds and schedules. The longer argument is in why a child should still learn to code in 2026.

Delivery

A live class for every part of Diemen

From Diemen-Noord across the railway to Diemen-Zuid and the Sniep, the town is compact, and a lesson on a laptop is the one journey that takes no time at all.

No connection to catch

A learner in Oud-Diemen and a learner in Holland Park start the same lesson at the same moment, each from home, with no metro or train in between.

School words in Dutch

Groep, brugklas, vmbo, havo, vwo and profielkeuze stay in Dutch, as Diemen families use them, while the teaching is in English.

The first hour is free

It is a real lesson on a real task. The teacher then recommends a level, a course and a regular time, and asks for no payment details.

Groups from further afield

Five to ten learners at the same stage. Diemen has 4,794 residents under fifteen, too few to fill every level and hour locally, so groups include learners from other places and countries.

Regio Noord holidays

Twice a week, about eight lessons a month, at a fixed hour, pausing for the regio Noord holidays that Noord-Holland schools keep.

Teachers a few hours ahead

The teachers are in India, three and a half hours ahead of Diemen in summer and four and a half in winter, so late afternoons, evenings and weekend mornings all work.

Eight schools, many connections, and one group online

Diemen has 7 primary establishments teaching 2,423 pupils and one secondary establishment. A coding group needs five learners who match on subject, stage and hour, and they are found far more easily across all ages from 6 to 67 and many countries than inside one small municipality.

Fees

What language are lessons in, and when are they?

In English, with Dutch school terms such as brugklas, havo and vwo kept as they are. The teachers work from India, three and a half hours ahead of Diemen in summer and four and a half in winter, so late-afternoon, evening and weekend times are easy to arrange. The time is agreed in the free lesson, and regio Noord holidays are kept.

Is there a Modern Age Coders classroom in Diemen?

No, and none is claimed here or anywhere in the Netherlands. All teaching is live and online and needs a laptop or desktop, working audio, a current browser and a connection that holds. The telephone number shown on this page is an Indian one and is described as such.

What do Diemen coding classes cost?

The first lesson is free. After it, group tuition is USD 100 a month for two live lessons a week, normally eight across the month, in a group of five to ten learners. One-to-one tuition is USD 150 a month at the same frequency with a single teacher. Course, format, recurring hour and availability are all confirmed before anything is paid.

How many learners are in a group?

Five to ten, matched on level, pace and goal rather than on age, school or address. One-to-one means a single learner with a single teacher. When no group at the right level is running, a family can take one-to-one lessons or wait for the next group to form.
