Komixy #StrangePlanet od Nathana W. Pylea úplně žeru. Mám hned několik triček s úryvky a citáty.
A teď jsem zjistil, že Nathan bude na letošním #WebExpo! Nemůžu uvěřit, že můj komixový idol bude tady v Praze na konferenci.
Na koho se ještě těším? Vitaly Friedman, Michal Špaček, Petra Dolejšová, Petr Brzek, @jnv (přednáška o #ActivityPub!), Jan Čurn…
Pokud se taky chcete těšit, kupón Javorek24 vám dá 15% slevu na lístek 🎁

10 years ago, at his #bono13 talk, @vitalyf was struggling with massive technical problems. This time, he delivered an extremely confident, highly informative presentation on a topic that is likely to be very exciting for many teams and projects: How can we measure design performance?
It was a great pleasure to have you on stage again, Vitaly!

After a short break, our #speakAtBono23 carousel is spinning again — and we have to hurry to introduce the remaining speakers, because in just 4 days we will already meet in Nuremberg.
With us again: designer, @smashingmag co-founder and Jack of all trades @vitalyf. Whenever we meet, I find Vitaly to be one of the most open, friendly and positive people I know. What a great personal pleasure to welcome him back on our #bono23 stage.

FYI: ~10 tickets left at the moment…

Please check out the post above for #poll
Full disclosure, the nice Russian man that gave me the oscilloscope said that it's like they were building things in another universe. He said that the way they built it just doesn't make sense. 😂
So Vitaly is; 1) Russian 2) the most ingenuitive #engineer that I've ever interacted with.
😂
Of course, not being able to read what all of the dials do isn't helping!

Little Mathematics Library – Stereographic Projection
We now come to another book in the Little Mathematics Library titled Stereographic Projection by B. A. Rosenfeld and N. D. Sergeeva. As the title suggests the book deals with projections on planes.
The present booklet is devoted to proofs of the aforesaid properties of the stereographic projection and to the presentation of some of its applications. The booklet consists of eight sections dealing with different properties of projections. …The booklet is aimed to be used in the senior grades of the high schools and by the first- and second-year students.
The book was translated from the Russian by Vitaly Kisin and was first published by Mir in 1977. All credits to the original uploader.

Sections and description:
1. Definition and Basic Properties of the Stereographic Projection 11
Sec. I gives a definition of the stereographic projection and proofs of its basic properties.
2. Stereographic Projection and Inversion 20
In Sec. 2 we establish the connection between the stereographic projection and a remarkable transformation of a plane onto itself in which the circles are also transformed into
circles or straight lines and the angles between the lines are transformed into the angles equal to them – this transformation is called the inversion with respect to a circle; in the same
section we establish the relation of the stereographic projection to the similar transformation of space – the inversion with respect to a sphere.3. Proof of the Properties of the Stereographic Projection by Means of Coordinates 25
In Sec. 3 the basic properties of the stereographic projection are proved in a different way, namely by means of coordinates.
4. Spherical Metric on a Plane. Application of Complex numbers 30
Sec. 4 establishes the relation between the stereographic projection and the complex numbers: when the projection plane is considered to be a plane of a complex variable, mapping of complex numbers by the points on the sphere is realized by means
of a stereographic projection. This mapping is frequently utilized in the theory of functions of complex variables since the so-called point at infinity of the plane of the complex variable, which cannot be mapped on the plane itself, is given on the sphere by the very projection centre. The same section discusses the so-called spherical metric on a plane when the distance between two points of the plane is assumed equal to a spherical distance between the corresponding points on the sphere; this distance is expressed in the simplest form by means of complex numbers.5. Mapping of Sphere Rotations on a Plane 37
In Sec. 5 we show how the rotations of the sphere are mapped by the plane transformations in the stereographic projection; these transformations are also expressed most simply by means of complex numbers.
6. History of the Stereographic Projection 40
Sec. 6 gives an account of the history of stereographic projection which was developed already in antiquity and was very popular in the Middle Ages.
7. Application of the Stereographic Projection to Astronomy and Geography 42
Sec. 7 describes how the stereographic projection applies to astronomy – medieval astrolabes were based on this projection – and to geography where this projection is used to draw nautical maps.
8. Application of the Stereographic Projection to the Lobachevskian Geometry 47
Sec. 8 presents the definition of the Lobachevskian plane, demonstrates how a peculiar
stereographic projection can yield a projection of the Lobachevskian plane onto an ordinary plane so that the circles and some other curves on the Lobachevskian plane are mapped as circles or straight lines while the angles between the lines of the Lobachevskian plane are mapped as the angles equal to them.Bibliography 54

Я сделал Телеграм бота для Evernote, о котором немного мечтал годами
Прывітаначкі, похоже с одной стороны сегодня программистов нужно меньше чем раньше, с другой стороны - благодаря LLM действительно можно делать задачи на порядок быстрее. Предполагаю, что в ручную этого бота я бы делал месяц, через Codex gpt-5.5 xhigh - часа три. В Evernote у меня записано много идей. Хорошо бы то, хорошо бы это. И таки некоторый прогресс в их реализации есть. И вот недавно - открываю официальное приложение Evernote на iPhone, а заметки не загружаются. У меня самый дорогой премиум аккаунт. Вот так стало понятно - надо делать. Про другие неофициальные клиенты: Я мантейнер Geeknote - неофициальный CLI на Питоне, он внутри моего бота. NixNote на C++ CliNote на Go - недавно заархивирован - feel free to форкнуть и починить. И вот теперь я сделал Телеграм бота https://gitlab.com/vitaly-zdanevich/bot_telegram_evernote На Питоне - хотя я предпочитаю Go - но Geeknote зависимость на нём, так что для единообразия. Этот бот selfhosted - то есть у каждого он свой. Выбрал такое решение из-за безопасности - вам не нужно доверять моему серверу - запускаете Terraform команду - и бекенд из одной лямды разворачивается у вас. AWS Lambda - для такого сервиса это значит бесплатный бекенд - на 3 GB ARM инстансе это около 4000 бесплатных вызовов в месяц, если среднее время работы будет составлять очень медленные 10 секунд (обычно отвечает за несколько секунд).

Ein Quanten-Preis zum Quantenjahr
Im letzten Jahr hat die Entscheidung des Preiskomitees, den Physik-Nobelpreis 2024 an John J. Hopfield und Geoffrey E. Hinton für ihre wegweisenden Entdeckungen und Entwicklungen, die maschinelles Lernen mit künstlichen neuronalen Netzen ermöglichen, zu verleihen, die Bandbreite der Physik und ihrer interdisziplinären Bedeutung für Fortschritt und Gesellschaft verdeutlicht: Physik ist mehr.
In diesem Jahr scheint das Komitee zu den Wurzeln der Physik zurückzukehren, ohne dabei die Zukunft aus den Augen zu verlieren: Am 10. Dezember 2025 wird John Clarke, Michel H. Devoret und John M. Martinis der Nobelpreis für Physik 2025 „for the discovery of macroscopic quantum mechanical tunnelling and energy quantisation in an electric circuit“ verliehen werden, also letztlich für die sehr konkrete Erforschung und Anwendung physikalischer Grundkonzepte, die dann auch zur Entstehung der Quantentechnologie als neues Fachgebiet beigetragen haben. Selten habe ich beim Lesen des wissenschaftlichen Hintergrunds zum Preis so viel verstanden wie in diesem Jahr. Selten ist so deutlich geworden, wie diese Grundlagen und Konzepte in die Arbeit der Preisträger eingeflossen sind, in Teilen auch eine Reise durch die Geschichte des Nobelpreises und seiner Träger (und viel zu wenigen Trägerinnen).
Die Physik-Nobelpreisträger 2025: John Clarke, Michel Devoret und John Martinis. // Illustration: Niklas Elmehed © Nobel Prize OutreachIn ihren Experimenten, die die drei Preisträger gemeinsam an der University of California durchführten und deren Ergebnisse sie unter anderem in
- M. H. Devoret, J. M. Martinis, D. Esteve, J. M. Clarke, „Resonant Activation from the Zero-Voltage State of a Current-Biased Josephson Junction“, Phys. Rev. Lett. 53, 1260 (1984),
- M. H. Devoret, J. M. Martinis, J. Clarke, „Measurement of Macroscopic Quantum Tunneling out of a Zero-Voltage State of a Current-Biased Josephson Junction“, Phys. Rev. Lett. 55, 1908 (1985) oder
- J. Clarke, A. N. Cleland, M. H. Devoret, D. Esteve, J. M. Martinis, „Quantum Mechanics of a Macroscopic Variable: The Phase Difference of a Josephson Junction“, Science 239, 992 (1988).
veröffentlichten, zeigten sie, wie Quantentunneln auf makroskopischer Skala in einem elektrischen Schaltkreis mit zwei Josephson-Kontakten messbar wird.
Basis für diese Experimente war das Wissen um
- den Tunneleffekt als solchen, wie ihn George Gamow 1928 als quantenmechanischen Prozess beim Alpha-Zerfall eines Atomkerns beschrieben hatte,
- die Erklärung des Phänomens der Supraleiter durch Cooper-Paare in der B(ardeen)C(ooper)S(chrieffer)-Theorie (Nobelpreis für Physik 1972),
- die Arbeiten von Leo Esaki und Ivar Giaeve zu Tunneleffekten in Halb- und Supraleitern, sowie von Brian David Josephson zur theoretischen Vorhersage des inzwischen nach ihm benannten Josephson-Effektes (Nobelpreis für Physik 1973 und
- die Beiträge von Alexei A. Abrikosov, Vitaly L. Ginzburg and Anthony J. Leggett zur Theorie der Supraleitung und Suprafluidität (Nobelpreis für Physik 2003).
Insbesondere die theoretischen Arbeiten von Anthony Legget über makroskopisches Quantentunneln in Josephson-Kontakten gaben den Anstoß zu den von Clarke, Devoret und Martinis durchgeführten Experimenten. Last but not least wurde und wird das von den Preisträgern experimentell geschaffene makroskopische Quantensystem gerne mit dem von Erwin Schrödinger (Nobelpreis für Physik 1933) in einem Artikel von 1935 ersonnenen Gedankenexperiment zur Übertragung quantenmechanischer Begriffe auf die makroskopische Welt, Schrödingers Katze, verglichen.
Soweit die geschichtlichen Aspekte des Preises, letztlich haben die Arbeiten der diesjährigen Preisträger aber Tür und Tor für neuere und zukünftige (quantentechnologische) Entwicklungen geöffnet:
- Künstlichen „Atome“ auf makroskopischer Skala, durch die weitere Quantensysteme simuliert werden konnten und können, was zu einem tieferen Verständnis quantenphysikalischer (mikroskopischer) Effekte führt.
- Qubits (Quantum Bits) in Supraleiter-Schaltungen sowie die cQED (circuit Quantum Elektrodynamics) als Bauelemente von Quantencomputern.
Fachgebiete, wie z.B. die Quantenoptik, konnten ihr Forschungsspektrum auf Bereiche ausdehnen, die atomphysikalisch nicht zugänglich sind, was sehr schön in der Arbeit des Exzellenzclusters PhoenixD am Beispiel konkreter Demonstratoren zu sehen ist.
Eine eigene Zusammenfassung ihrer Arbeiten geben Clarke, Devoret und Martinis mit einem 2020 erschienenen Artikel in Nature Physics: Quantum Josephson junction circuits and the dawn of artificial atoms.
Wer darüber hinaus weitere Fachliteratur zu den Forschungsthemen des Physik-Nobelpreises 2025 erkunden will, wird selbstverständlich im TIB-Portal fündig, z.B. mit Suchanfragen nach den Schlagworten
Auch die freie Suche nach Qubit Josephson liefert viele interessante Treffer und zeigt mit der hohen Zahl an Patentinformationen die Relevanz dieser Themen für industrielle Anwendungen.
Wie in jedem Jahr teste ich die arXiv-Affinität der Preisträger und bin 2025 erfreut: Sowohl John Clarke als auch Michel H. Devoret und John M. Martinis sind mit einer großen Zahl an Papern auf arXiv vertreten.
Umfangreiche Publikationslisten der drei Autoren lassen sich selbstverständlich in kostenpflichtigen Literaturdatenbanken, wie zum Beispiel Web of Science oder Scopus erfragen, eine „offene“ Variante ist die Nutzung von OpenAlex. Hier sind von John Clarke über 700, von Michel H. Devoret mehr als 500 und von John M. Martinis über 600 Veröffentlichungen nachgewiesen. Dass es sich mit hoher Wahrscheinlichkeit um die richtigen Autoren handelt, lässt sich über die ausgezeichneten Filterfunktionen in OpenAlex feststellen.
Die 2025 Nobel Prize Lectures in Physics können wir am 8. Dezember 2025 ab 9 Uhr live verfolgen.
Für eine funktionierende Wissenschafts- und Publikationskultur
Auf eine weitere wichtige Aktivität der den Nobelpreis für Physik zu verantwortenden Organisation, der Royal Swedish Academy of Sciences, möchte ich an dieser Stelle hinweisen: Im Sommer 2025 hat diese einen Workshop veranstaltet, der sich mit dem zunehmenden Problem von Fake Science in Publikationen befasst hat. Entstanden ist dabei die Stockholm Declaration, die neben einer guten Übersicht bisheriger Deklarationen für Reformen im wissenschaftlichen Publikationswesen kurz und prägnant wesentlichen Punkte zur Sicherstellung einer auch in Zukunft (und in Zeiten Generativer AI) funktionierenden Wissenschafts- und Publikationskultur aufführt. Mögen sie in den Communities Gehör finden!

One UI 8 Showcase [Galaxy Tab S8]
The Galaxy Tab S8 has recently received the One UI 8 update that was first released this July for the Galaxy Z Fold7 and Flip7 foldables, as well as the Flip FE. It brought Now Brief to the foldables and to the tablets, but it only reached the newest devices. The Galaxy Tab S8 misses out on some features, such as Now Brief that shows you daily briefing.
Rolling out One UI 8 to the majority of the devices was a huge leap forward, especially when those devices are eligible, and the flagship devices that recently got the update (excluding the FE) included:
- Galaxy S25 series
- Galaxy S25 Edge
- Galaxy S24 series
- Galaxy S23 series
- Galaxy S22 series
- Galaxy Z Fold6/Flip6
- Galaxy Z Fold Special Edition
- Galaxy Z Fold5/Flip5
- Galaxy Z Fold4/Flip4
- Galaxy Tab S10 series
- Galaxy Tab S9 series
- Galaxy Tab S8 series
While there are some eligible devices that didn’t get the update yet, we’ll showcase the One UI 8 experience on the Galaxy Tab S8 to see what new features made it to the tablet.
This is the first thing that you see once your tablet updates to One UI 8. The introductory screen shows you the Galaxy AI features, before telling you that you’re set. You can see what’s new from the Tips application to learn more about the update, as well as the official changelogs.
In the software information page, you can see that the tablet is now successfully running One UI 8.0 based on Android 16, and that it’s now running off the EYJ4 build that was compiled on October 16th.
Let’s get straight to the point. However, we won’t showcase all features, but we’ll showcase the most of them. In the lock screen editing option, you can now add more widgets! Before, you used to only be able to add four, three, or two widgets, depending on their size. Now, more widgets have been added, including the calendar, so that you can now have access to more key information effortlessly.
When you open the lock screen editing feature, you’ll notice that the widget area became larger than before, allowing more widgets to be placed.
This is good, especially if you want more information to show up on your lock screen. For example, you can insert a full calendar, a 2×2 photo, or anything else to the lock screen.
Not only that, you can now rotate the widgets to relocate them to the left side of the screen. However, you can’t move them to the right side of the screen. This feature is going to make your lock screen look more informational, as you can see below.
Not only that, but you can also add multiple instances of some widgets, such as when you need to show two different pictures.
In the Live Notifications settings, you can now enable both Google Finance and Sports from Google. Those weren’t available in One UI 7 for the Galaxy Tab S8, but you can now get finance and match information on your Now Bar, as well as the live notifications.
Of course, you’ll have to configure both to get them to work on your Now Bar. In Google Finance, you’ll have to add stocks to your watchlist, such as DOW JONES, NASDAQ, and so on.
As for Sports from Google, you’ll have to follow leagues and teams. For example, you’ll have to follow leagues like LaLiga and UEFA Champions League, and teams like Real Madrid, Barcelona, and Juventus. You can also follow more teams from not only the soccer game, but other sports games like basketball, cricket, baseball, hockey, rugby, and American Football.
If you want deep analysis of a match that you’re interested in, you’ll have to download Sofascore to obtain more analytical information about a specific match. This app won’t conflict with Sports from Google since Sofascore doesn’t support Now Bar yet. We are not affiliated with Sofascore, but it’s our recommendation.
Download SofascoreOnce set up, you should be able to see match information on your lock screen and in your status bar.
As for Quick Share, it has been updated to make sharing files easier than never before. Just press on the Quick Share button on your quick settings panel, and you’ll be greeted with this screen.
Then, either follow the usual steps and connect to the target device, or become a receiver.
In your notes on Samsung Notes, you can finally add sticky notes to them. They act like temporary notes that are independent from your final note. Just press the Add button, and press Sticky note.
After that, a sticky note will appear. Write down some notes. You can change its appearance, such as color.
In both the Recents and the Downloads screen of My Files app, you can now filter the list of files based on app, such as Chrome and others.
When it comes to multitasking, you can now achieve the 90:10 aspect ratio to maximize your productivity. One app shows on your screen, and the other stays hidden until you press on it. This is useful if you want to get information from two apps without having to leave the current app.
This makes your tablet a productivity powerhouse, further enhanced by the ability to open three apps side by side. One UI 7 and earlier didn’t allow this, but we’ve seen this kind of improvement thanks to One UI 8.0.
When you’re in tablet mode, you can drag the small handle in the top edge of the screen, and drag it down to make a DeX workspace that works like your desktop. From then on, you can open multiple apps as if you’re on a desktop.
Once done, the final result is similar to this:
You can also snap a window left and another window right by pressing the drop down menu at the top of the application, and selecting one of the options.
In the Reminder app, you can now see some of the suggested reminders to quickly start making reminders.
Once you add reminders, you’ll be met with a list of reminders that you can quickly filter through.
For the calendar, it has been redesigned to allow you to list all events in a single day without opening a separate window, allowing you to add and manage events more quickly.
You can also add events and reminders straight from the quick add menu from the calendar without having to open the Reminder app. This increases productivity since you don’t have to open another app just to add a reminder.
You can now choose to hide all notifications on your lock screen to prevent anyone from seeing your notifications from your lock screen. Open the notification settings > Hide content while locked.
The resulting notifications will then look like this:
Side note: the notification panel background uses the background blur that is similar to how the flagship Galaxy Tab S11 tablets render their notification panels to achieve uniformity. The panels in this update for the Galaxy Tab S8 work similarly to Android 4.2 Jelly Bean. To learn more, visit our article.
For accessibility needs, you can now magnify your keyboard. The zoom panel will automatically pan to whatever text you’re writing so you can clearly see what you’re writing.
You can also use your physical keyboard (Bluetooth or wired) to control your tablet’s mouse pointer, should you not want to use your mouse. Just use a combination of key shortcuts that are laid down below to control your mouse, similar to Windows’ built-in Mouse Keys, macOS’ built-in feature, and xdotool for Linux.
To activate this feature, you’ll have to press CMD + ALT + 4 (Start key for some keyboards). Afterwards, you can use the following keybindings:
Key combinationDescription / Action8Move mouse upkMove mouse downuMove mouse leftoMove mouse right7Move mouse left upwards9Move mouse right upwardsjMove mouse left downwardslMove mouse right downwardsiPrimary mouse button (left)/Secondary mouse button (right)mClick and hold,Release.Enter or exit scroll mode8Scroll upkScroll downuScroll leftoScroll rightNow, you can add more preset routines, including those with advanced conditions, such as routines that run when a weather forecast is, for example, rainy.
For example, you can add a routine called “Battery check before bed” that tells you aloud how much charge your tablet has before going to bed, with it also telling you to charge your tablet when the battery level is below 40%.
For routine conditions and actions, you now have even more routines to supercharge your automation.
If you have a group of alerts, you can now add existing alerts to an alarm group. When you click on the plus button, you can now add either a new alert or an existing alarm. If you’re planning to add existing alarms, all of them will be selected, and you can choose alarms as you like.
Once done, an existing alarm will be added to the group.
Not only that, but you can now also manage alarm groups straight from your home screen by adding a widget that shows you an alarm group. From there, you can turn all alarms on/off by a single button press.
Additionally, you are now allowed to choose how to display pop-up notification styles for critical alerts (Instagram DMs, important E-mail messages, and more) for an individual app instead of for all apps. Using a new settings option, you can now configure this to make an application either stand out or show a brief notification.
With the refined Weather app, you can now look at realistic weather representations at the top of the screen that shows you the actual weather conditions. This banner changes according to both the time of day and the weather condition. Scrolling down is a bit jerky until this banner becomes off screen, but it’s otherwise smooth.
You can add more DeX desktops by pressing this button in the Recents screen.
As for the dialog boxes, they now earn blurred transparent background. This makes those dialog boxes look attractive.
The Security and Privacy settings gets a minor redesign with the security overview being a wide box instead of a black panel showing you a large shield icon.
As for the Device Care screen, only the indicator text gets a color according to the state.
One UI 7 used to bring the two shortcuts in the lock screen closer to the center of the screen, as you can see below.
Now, One UI 8 brings them closer to the two edges of the screen, just like what One UI 6.1.1 and earlier brought.
Now, let’s document the Scroll and Translate feature that we got through the One UI 8.0 update. When you initiate translation in a specific screen (website, app, and more), you can now effortlessly scroll and translate without having to close and open Circle to Search again and again.
When you scroll down, what is shown on the screen will be translated.
One UI 7 used to show you the live notification details in the middle of the screen, just like this.
Now, starting with One UI 8, the details will show closer to the upper left corner of the screen.
One UI 8 also suggests wallpapers for you, and places the suggestions to its own area.
When you tap on Suggested images, you’ll be able to see all suggested images below:
When you click on one of the suggestions, you’ll be taken to a screen where you edit the lock screen prior to applying the wallpaper. Afterwards, the wallpaper is set.
You can also change your wallpaper to the dynamic image as in below:
Once set, the wallpaper changes its color over time. There is a new animated clock style in One UI 8 that is a bit different to what One UI 7 provides.
Along with all the clock styles, comes the adaptive clock style that you can use with the picture of either a person or an animal.
It works with all styles that use the selected font style for your clock. Depending on the picture, the adaptive clock automatically chooses the best position, but you can choose it manually. The result of the above configuration is shown below.
Depending on the wallpaper, you have more options for the color palettes.
The adaptive clock also works with LockStar, and it allows you to be even more flexible with the clock style.
Once done, the lock screen will look similar to this:
Of course, whatever is on a subject, as long as it includes a picture of either a person or an animal, will be considered a subject for the adaptive clock to adapt to. For example, a laptop in the below picture is considered to be a subject.
The result will look similar to the below picture.
This also works with pictures that are meant to be used with phones, but the space for the adaptive clock is rather limited. For example, take a picture of a woman holding her headphones.
The result looks similar to below:
However, the adaptive clock doesn’t work with subjects that are neither a person nor an animal, such as buildings or abstract wallpapers.
Folders now have a very nice transparent background, with a brighter border that makes it even more beautiful.
As for the predictive back gestures, you can turn it on by going to Settings > Advanced settings > Labs > Back swipe preview. Make sure that your navigation bar is set to use gestures instead of buttons, because the predictive back gestures depend on the gestural navigation to work.
Once done, you should be able to see a preview of the screen you’ll go back to, though it depends on an application.
That’s all for this showcase. Your Galaxy Tab S8 should be able to update to One UI 8 as it’s already released. Next, we will test our .NET applications with One UI 8.0 to ensure that we give proper support.
To obtain the update, perform the following steps:
- Open the Settings app
- Navigate to Software Updates
- Tap on Download and Install
- Wait until you see One UI 8 at the top of the page, then tap on Download
- Wait for the download to complete, then tap on Install
After you perform the above steps, your tablet will be running One UI 8 based on Android 16, and you can enjoy its new features and with many improvements on place. This makes sure that your experience gets improved.
If you still didn’t get the update for your device, wait for a few days or a few weeks, then check for updates again. If you still see “Your software is up to date,” this means that the update didn’t reach your region yet.
Note that the update process may take 15 to 20 minutes, and this can vary from device to device. The download process may incur extra charges if you’re using the cellular network as the update size is around 3 GB, depending on the device, so we recommend downloading it through Wi-Fi. Never interrupt the update process in any way, or problems may occur. Make sure that your tablet gets charged before you initiate the installation process.
