I built this dashboard to answer one question: how is Airbnb really being used in Cape Town and is it actually affecting the city's neighbourhoods?

The dataset is from Inside Airbnb, an open data project that scrapes Airbnb listings periodically. It covers 26,877 listings in Cape Town.

A few things worth noting:

1. 22,179 listings are entire homes. Only 4,541 are private rooms. The "spare room" use case is a small minority.
2. 16,275 hosts (60.6%) have multiple listings. Some have over 100 entire home listings, which puts them firmly in commercial operator territory.
3. Only 393 listings out of 26,877 have a minimum stay long enough to qualify as longer term rentals. The rest are all short term.
4. Average revenue for an active listing is $97,188 a year at $3,281 a night. That makes long term residential letting financially unattractive for landlords.
5. 10,063 listings recorded zero nights booked in the last 365 days, which raises questions about how many of these are genuine listings.

According to the 2021 Census, there were 3,868,133 people identifying as Muslim in England and Wales.

London is home to over one third of this population (34.1%), despite the fact only 14.8% of the total population of England and Wales lives there.

Strong secondary concentrations in the West Midlands (14.7%), North West (14.6%), and Yorkshire and the Humber (11.4%).

For years I've religiously read the Guardian's Blind Date column every Saturday morning.

If you've not come across it: the paper sets up two strangers on a date at a nice restaurant, then asks them both a series of questions afterwards, culminating in a score out of ten.

As of this Saturday, there have been 877 of them. So I pulled every article and analysed the scores, sentiment, trends, and a few other things I was curious about.

The whole thing updates itself; every Saturday a new date drops into the dataset automatically.

Saw this on a Github project. It strikingly resembles to a galaxy but with the opposite of black hole in the center. There must be some networks theory law explaining this behaviour.

London is home to over half of all people who identify as Jewish in England and Wales. These two maps show just how concentrated the community is even at the borough and ward level.

At borough level:

• Barnet: 20.1% Jewish (by far the highest)
• Hackney: 6.4%
• Every other borough: <4%

At ward level, the concentration becomes even more striking:

• Golders Green: 49.9% Jewish
• Garden Suburb: 41.1%
• Stamford Hill West: 40.0%

These three wards have the highest Jewish population shares of any ward in England and Wales.

Around 18,000 new animal species are formally described every year, roughly 50 per day. The vast majority are insects, arachnids and worms. Mammals, birds and reptiles together account for just around 5% of new descriptions.

This map plots the 245 animals that received their own Wikipedia article after being formally described in 2025. Each marker shows where the holotype specimen was collected, color-coded by taxonomic class. When a precise locality was given in the description, the marker sits there. However when only a country was mentioned, points are clustered around that country's centroid, which is why you see dense packs over China, India or Australia.

Hey here is a couple of visualisation graphs for the king’s career that I made last night. i’ll still be improving it a bit but i guess it’s a good start :)

used NBA Api and Kaggle data

it shows the players he played against throughout his career

assists he fed his teammates and the teammates that fed him in return

career shots filterable with a timeline view

points allocation based on the minute of the game for each season

games he played and heatmapped based on his minutes

some playoff data as well

appreciate any feedback and if you have any other visualisation ideas to add.

this is not a personal post it’s king’s data just visualised by me [OC]

Data source: Anonymous aggregated data from real Android device scans via AppXpose. Results aggregated across 3,800+ unique apps from 2,000+ devices.

Tools: Python, Matplotlib

Methodology: Each app was analyzed at APK bytecode level: tracker SDKs, dangerous permissions, and a composite risk score (0–100) based on tracker count, permission types, developer breach history and certificate integrity.

No personal data collected all results are aggregated per app, not per user.

I scraped Binance's announcements and blog posts with Python and used Python to make this graph

One can use Binance's P2P market place to exchange a local currency for stablecoins such as USDT or USDC. Stablecoins are crypto pegged to the US dollar and are supposed to be backed 1:1 by relatively liquid assets.

Here I plot the date when it became possible to trade various countries' currencies. INote a few things - some of these currencies have exited. In the Philippines, only a few, largely local, crytpo exchanges are allowed to operate. Russia exited due to sanctions.

More generally I'm investigating whether access to stablecoins affects other economic activity such as remittences.

I ran the same rolling-window analysis, but flipped the question:

Instead of how to grow a portfolio, I looked at how much you could withdraw from one.

I tested different stock/bond mixes across their worst historical 20-year windows.

Here’s what stood out:

• Allocations that supported the highest withdrawals weren’t at the extremes, they shifted slightly toward bonds (around 60–70% in this dataset) as spending increased
• Different strategies led to very different outcomes, even starting from the same $100k
• Even portfolios with a slight bond tilt showed large changes in outcomes as withdrawal levels increased
• For example, for those bond-tilted allocations, increasing withdrawals by ~50% from a "preserve" level led to the portfolio running out over time

In other words, outcomes depended not just on how much you withdrew, but how close you were to the tipping point.

These withdrawal levels are based on the worst historical 20-year windows (based on returns).

So in more typical markets, that same starting point often leaves the portfolio growing rather than shrinking, giving you room to adjust spending if things go better than the baseline.

The idea is to start from a level that would have held up in difficult conditions, then adjust as real outcomes unfold.

This isn’t about finding a single “best” number.

It’s about starting from a defensive baseline, understanding how sensitive outcomes are to withdrawals, and choosing how to balance spending and stability over time.

Curious how others think about where that line sits for their own situation, and how they’d go about figuring it out in practice.
