What actually keeps a database's data safe through a crash?

Can you check every figure on this site yourself?

Can people keep writing together when the network drops?

Why did the cost per conversion jump four times over?

How much can you trust a single air-quality reading?

Is this render right, or does it only look right?

What has been built in public, and how much of it is real code?

Did the migration really move everything, and can it say why not?

Can one place decide what reaches the network, the camera and the mic, and keep a record?

This is what driving into each ring opens, as plain text. Tap a stamp to see how the figure is known.

Engines, sync and guards: the work where the question is what stays true when things go wrong.

NitroDB
What actually keeps a database's data safe through a crash?
68unit and integration tests
60,000writes in a recorded run of the real engine, drawn as its own SSTable files on each level, from the first flush to after compaction
42concurrency outcomes checked, 0 failed
Open the NitroDB caseNot collected yet
SyncState
Can people keep writing together when the network drops?
226characters in the text two Yjs replicas merged to after 40 recorded steps, drawn as two threads that part and then braid. Yjs is the library SyncState builds on
YjsCRDT library behind the merging (integrated, not written from scratch)

Appwrite Migration Guard
Did the migration really move everything, and can it say why not?
11 of 11planted changes caught in a live pass, no false positives
8commands, all working against live Appwrite Cloud

SecureHost Control Suite
Can one place decide what reaches the network, the camera and the mic, and keep a record?
4components: core library, service, GUI, CLI
3default policy rules

Funnels, receipts and a city of repositories: the work where the question is what the numbers really say.

Ledger vault
Can you check every figure on this site yourself?
48claims sealed in a hash chain: each seal is the SHA-256 of the one before it and the claim itself, and your browser re-checks the whole chain

Growth Intelligence Lab
Why did the cost per conversion jump four times over?
98.1%of the cost increase happened after the click
19.2xmore spend in the larger campaign
44tests

Repository city
What has been built in public, and how much of it is real code?
27public repositories drawn as towers, taller for more code, coloured by language, with a bead on those pushed in the month before the latest push

Sensors and light: the work where the question is how much to trust a measurement.

AetherScan
How much can you trust a single air-quality reading?
11data sources, each with licence, rate limit and how provenance is kept
366days of Dehradun air quality from a file in my own files (PM2.5 from 5.4 to 155.3), drawn as a skyline that is tall in winter and low in the monsoon. The file states no source
12backend test files, each named test_*.py

1.81Msamples a second, checked against an analytical answer
