What does it do?

The analyzer can be used in two ways:

• Simulation with a known answer automatically calculates the familiar green, yellow and grey tiles after each guess.
• Manual analysis lets you reproduce a game in progress by setting the tile colours yourself.

After every move, the app filters the remaining candidates and ranks possible next guesses. The ranking includes entropy, worst-case and average bucket size, the chance of an immediate hit and the estimated average number of moves required to finish.

A bucket is simply a group of answers that would produce the same colour pattern for a given guess. A good move should split the remaining words into small buckets, making the next decision easier even when it does not hit the answer immediately.

Explore strategies

The game history shows how quickly each guess reduced the candidate list. You can return to an earlier move and try another path without rebuilding the whole game.

There is also a starting-word solver. Give it an opening word and a move limit, and it will test the resulting strategy against the answer dictionary. The histogram shows how many games are solved in one, two, three or more attempts.

The dictionary combines five-letter forms from SJP.PL with the KWJP100 frequency lists and morphological data from PoliMorf. A filter hides unlikely inflected forms by default, while keeping them available when needed.

Built for the browser

Słowo Analyzer is a static React and TypeScript application built with Vite. Ranking and solver calculations run in a Web Worker, so the interface remains responsive while more expensive strategies are evaluated. The app stores its dictionary cache and preferences locally and can work offline after the first visit.

Everything runs in the browser—there is no account, no backend and no game data sent to a server.

Starlink rocket ascending through the night sky, with Venus visible at the bottom.

From Goleta, located roughly 90 kilometers (60 miles) southeast of Vandenberg, the view was spectacular. In the first photo, you’ll notice the dramatic fiery exhaust trail cutting across the night sky. That small glowing point beneath the path of the rocket is Venus—providing a nice visual reference for just how bright this launch was.

Location

• Space Launch Complex 4E, Vandenberg SFB, CA, USA
  Find the best place to watch the launch from Vandenberg

Space Launch Complex 4E has witnessed 181 rockets lift off—every one of those an orbital launch attempt. Meanwhile, Vandenberg Space Force Base itself (established in 1941) has hosted 793 rocket launches. Originally built for military and missile testing, Vandenberg also supports civil and commercial space endeavors, including those by NASA and SpaceX. The base is operated by the United States Space Force’s Space Launch Delta 30, which manages the Western Range for space launches.

Closer look at the rocket exhaust plume and nose cone, highlighting the intense heat and glow.

In the second image, you can see the glowing rocket plume and the brightly lit nose cone with more detail. The exhaust’s shape and texture reveal the incredible energy at work, propelling the satellite payloads into orbit.

Watch a Launch Yourself

If you ever get a chance to be near Vandenberg or any other spaceport during a scheduled liftoff, be sure to check local viewing locations. There’s nothing quite like witnessing a rocket pierce the sky in real time.

This lead to creation of an extensive aurora oval that could be observed even from southern Europe. In Poland Aurora was visible even in zenith. Thanks to ALPS (All-sky Light Pollution Survey) - which I am a part of - aurora images were captured bu several of observing stations a.o. Ostrowik (ALPS-OST) and Sopotnia Wielka (ALPS-SOP).

But that’s not all! Last month on November 5th

The hero of this post is not as bright as Hale-Bopp but also can be seen by naked eye. Comet NEOWISE or C/2020 F3 (NEOWISE) is already circumpolar object (in Poland, at the time of writing this post) which means it does not set. It can be seen during whole night over the northern horizon. Comet was discovered March 27, 2020 and two tails (dust and ion) can be seen. The first one by eye and second one in photographs. The nucleus is estimated to be about 5km. As of 16 July brightness was about 2-2.5 mag.

Recently, I had the opportunity to capture C/2020 F3 (NEOWISE) at Bialkow Observatory. Despite the comet’s low altitude, sky in Bialkow is really dark. Along with cloudless nights, conditions for observations were excellent. Below is the photogpraph that I was able to take. Two tails are visible, bright dust one and faint bluish ion tail.

Other photos are present in gallery. I strongly encourage everyone to see this gorgeous comet. ☄️

In this first post I’d like to write a little about Jekyll project which I used to create this site. It is a very powerful tool for generation of blog-type static sites. It was written in Ruby programming language by Tom Preston-Werner, GitHub’s co-founder. I strongly recommend to familiariaze yourself with Jekyll, especially if you want to launch your website using GitHub Pages - it integrates very well with Jekyll.

Jekyll offers a very large amount of themes to choose from and most of them are free and customizable (if acknowledgment is provided). The one that I am using is called Minimal Mistakes. Another advantage is that most of the website development is done in markdown. Knowledge of Ruby language and html may come in handy if you plan to go beyond what is offered by chosen theme.

To get yourself started I can recommend this great tutorial made by Mike Dane from Giraffe Academy.
