General technical writing — architecture decisions, engineering problems, tools built to solve specific needs, and observations from running software in production.
The Military Flight Tracker helps you inspect aircraft records identified by the available public source as military-related. It is a view of observable records, not a complete inventory of military aircraft in the sky. A fixed headline such as “85 aircraft right now” becomes mis
The Ethereum Chain Swap Monitor displays available Ethereum DEX swap observations, pool information, and summary panels. Its scope is Ethereum. It should not be described as a complete cross-chain flow tracker merely because several protocols appear in the same interface.

The European Power Prices board makes available day-ahead observations easier to compare across bidding zones. It can help you understand a price curve or inspect a possible window for a flexible load. Before using that curve, establish the zone, delivery date, timezone, interval

Sun Live combines solar imagery with active-region and flare information. Those panels are useful together, but they are not interchangeable observations. A solar image, a NOAA region report, and a GOES X-ray measurement can have different update times. The first task is to ident

An exoplanet catalog becomes useful when you can compare worlds without mistaking an estimate for an observation. A planet's radius, orbital period and host-star properties can be measured or inferred with very different uncertainties. A colourful 3D point does not tell you what

The People in Space view in Celestial Lab answers two different questions: who the roster provider currently identifies as being in space, and where a crewed station is estimated to be above Earth. A roster entry is a person. A point on the globe is a station. Keeping that distin

Space-weather numbers become useful when they answer a practical question: should you check for an aurora, investigate a radio disturbance or simply keep watching? A bright solar image, a rising Kp index and a southward magnetic field describe different parts of the same system.

An asteroid headline usually gives you one alarming number and leaves out the context. The useful questions are more specific: when is the closest approach, how far away is it, how well is the distance constrained, and is the quoted size measured or estimated? Asteroid Watch brin

A live satellite map is useful when it helps you identify an object, understand its orbit and judge the age of the information. Moving dots alone cannot tell you whether a satellite is visible from your garden or whether two spacecraft are about to collide. In Celestial Lab, star

The Air Quality Slovakia board helps you compare available station observations without opening a separate page for each location. Begin with the station, measurement time, and pollutant coverage. A station's coloured category is useful context, but it is not a complete measureme

A launch schedule is a changing plan, not a list of guaranteed appointments. Launch Tracker puts upcoming launches, launch-site context, recent missions, and source information in one place. Its value is making that changing picture easier to read. The critical skill is distingui

The Crypto Perp Board brings funding and open-interest observations together so you can inspect differences between available venues. A useful comparison begins with three questions: which contract is this, what interval does the funding rate describe, and what unit is used for o

A vulnerability feed is useful when it helps you decide what to check next. It is less useful when a severe number is presented without the affected product, version, exposure, or fix. CVE Watch brings vulnerability information together; your task is to establish whether a partic

The MEXC–Gate price-spread monitor helps you find markets whose displayed prices differ across two exchanges. Its most useful role is screening: a large difference is a reason to inspect the pair, not proof that you can buy on one venue and immediately sell for that percentage on

The original MEXC–Gate study compared a week of public executions across the two venues. It found large differences in execution sizes, activity, and aggressive-side proportions. Those differences can help you ask better questions about a pair's trading conditions. They do not es
