The Soviet Pioneer Who Composed Music with Computers

In the heart of Moscow during the Cold War era, a brilliant physicist named Rudolf Zaripov was quietly revolutionizing the world of music composition. His groundbreaking work in algorithmic music creation not only challenged the Soviet Union's stance on cybernetics but also laid the foundation for today's AI-generated music.

The Birth of a Musical Rebel

Rudolf Zaripov's journey began in 1947 when, as an 18-year-old high school student, he noticed that musical harmonization could be described using mathematical rules[1]. This observation sparked a lifelong passion for merging music and mathematics, eventually leading him to create one of the world's first computer-generated musical compositions.

Defying the Soviet Stance on Cybernetics

In the 1950s, the Soviet Union viewed cybernetics as a capitalist threat, labeling it a “bourgeois pseudoscience”[1]. Despite this hostile environment, Zaripov persevered in his research, working on state-sanctioned cryptography projects by day and developing his musical algorithm by night.

The Breakthrough: “Ural Chants”

Zaripov's dedication paid off in the summer of 1959 when he successfully programmed the Ural computer to generate music[1]. The resulting composition, “Ural Chants,” sounded like an eerie yet beautiful organ rendition of early sacred music, marking a significant milestone in the history of computer-generated art.

Legacy and Modern Implications

Zaripov's work was groundbreaking not just for its technical achievement but also for its timing and location. He published the first academic paper on algorithmic composition in 1960, predating similar efforts in the West[1]. His research laid the groundwork for future developments in AI-generated music, influencing the field that continues to evolve today.

The Ongoing Debate

The legacy of Zaripov's work resonates in current discussions about AI-generated art. While some see it as a powerful tool for creativity, others, like composer John Supko, express concern about the potential misuse of the technology to create uninspired imitations of classical works[1].

As we continue to grapple with the implications of AI in creative fields, Zaripov's pioneering spirit reminds us of the potential for technology to expand the boundaries of human creativity. His work serves as a testament to the power of curiosity and perseverance in the face of political and technological challenges.

Sitzen macht alt: Warum auch junge, aktive Menschen aufstehen sollten

Wer hätte gedacht, dass unser Bürostuhl unser größter Feind sein könnte? Eine neue Studie der University of Colorado Boulder und der University of California Riverside liefert beunruhigende Erkenntnisse über die Auswirkungen von langem Sitzen – selbst für junge, aktive Menschen[1].

Die erschreckenden Zahlen

Die Studie zeigt, dass Millennials, also Menschen geboren in den frühen 80ern bis späten 90ern, durchschnittlich mehr als 60 Stunden pro Woche im Sitzen verbringen. Einige Teilnehmer gaben sogar an, bis zu 16 Stunden täglich zu sitzen[1]. Diese Zahlen sind alarmierend, denn sie erhöhen nicht nur das Risiko für Herzkrankheiten, sondern beschleunigen auch den Alterungsprozess.

Warum Ausgleichssport nicht ausreicht

Viele von uns denken, dass regelmäßiger Sport die negativen Auswirkungen des Sitzens ausgleichen kann. Leider ist dem nicht so. Die Studie zeigt, dass selbst die empfohlenen 20 Minuten moderate Bewegung pro Tag nicht ausreichen, um die Gefahren des vielen Sitzens zu kompensieren[1].

Die Folgen für junge Erwachsene

Besonders besorgniserregend ist, dass die negativen Auswirkungen bereits im frühen Erwachsenenalter sichtbar werden. Junge Menschen, die achteinhalb Stunden täglich sitzen und sich nicht ausreichend bewegen, könnten bereits in eine “mäßige bis hohe Risikokategorie” für Herz-Kreislauf- und Stoffwechselkrankheiten fallen[1].

Was können wir tun?

Die gute Nachricht ist, dass es Möglichkeiten gibt, dem entgegenzuwirken:

1. Regelmäßige Pausen: Stehen Sie so oft wie möglich auf und bewegen Sie sich.
2. Stehschreibtisch: Nutzen Sie die Möglichkeit, im Stehen zu arbeiten.
3. Aktive Meetings: Organisieren Sie Besprechungen im Gehen.
4. Intensive Bewegung: Versuchen Sie, täglich 30 Minuten intensiven Sport zu treiben.

Auch wenn es unbequem sein mag, unser Sitzverhalten zu ändern, zeigt die Studie deutlich: Es lohnt sich für unsere Gesundheit und unser Wohlbefinden, aktiv gegen das lange Sitzen anzugehen. Also, stehen Sie auf und bewegen Sie sich – Ihr zukünftiges Ich wird es Ihnen danken!

Apple erwägt radikal abgespeckte smarte Brille

Apple könnte in naher Zukunft eine neue, leichtere und kostengünstigere smarte Brille entwickeln, die sich stark von der aktuellen Mixed-Reality-Brille Vision Pro unterscheidet. Berichten zufolge plant das Unternehmen, eine Brille auf den Markt zu bringen, die sich auf Augmented Reality (AR) konzentriert und in ihrem Design den Ray-Ban Meta Smart Glasses ähnelt. Diese Brille wird voraussichtlich wie eine herkömmliche Hornbrille aussehen und könnte somit eine breitere Zielgruppe ansprechen.

Hintergrund zur Vision Pro

Die Apple Vision Pro ist ein innovatives, aber auch schweres und teures Gerät, das als VR-Brille konzipiert ist. Sie ermöglicht es Nutzern, die reale Welt durch Kameras zu sehen, was jedoch mit einem hohen Preis und einem beträchtlichen Gewicht verbunden ist. Bislang hat sich die Vision Pro nicht als großer Verkaufsschlager erwiesen, was Apple dazu veranlasst haben könnte, nach Alternativen zu suchen. Laut “Bloomberg” hat Apple im Rahmen eines Projekts namens “Atlas” bereits ausgewählten Mitarbeitern E-Mails geschickt, um Teilnehmer für eine bevorstehende Nutzerstudie zu finden.

Augmented Reality im Fokus

Die neue Brille soll ein essenzielles Feature der Augmented Reality bieten, indem digitale Informationen direkt vor die Augen der Nutzer projiziert werden. Dies könnte ähnlich funktionieren wie bei den MYVU-Brillen, die auf der IFA vorgestellt wurden und Funktionen wie Navigation, Teleprompter-Funktionen sowie Echtzeit-Übersetzungen ermöglichen. Die Integration von Lautsprechern in die Bügel könnte die Nutzungserfahrung weiter verbessern.

Konkurrenz und Marktentwicklung

Im Wettbewerb mit Meta und Ray-Ban ist Apple nicht allein. Mark Zuckerberg hat kürzlich ebenfalls eine ähnliche Brille vorgestellt, jedoch handelt es sich dabei derzeit nur um einen frühen Prototypen namens “Orion”. Die Entwicklung marktreifer Produkte wird voraussichtlich noch Jahre in Anspruch nehmen. Der Preis für die Herstellung solcher Geräte liegt derzeit bei etwa 9000 Euro, wobei das Ziel für den Endverbraucherpreis unter 900 Euro liegen soll.

Ausblick

Apple plant bereits für das kommende Jahr ein neues Modell der Vision Pro mit einem völlig neuen Chip. Eine günstigere Variante der Mixed-Reality-Brille wurde jedoch auf 2027 verschoben. Während Apple also weiterhin an der Vision Pro arbeitet, bleibt abzuwarten, wann und in welcher Form die neuen smarten Brillen auf den Markt kommen werden.

As a long-time Flameshot user, I recently encountered an annoying issue after upgrading to Gnome 41 on Wayland. Every time I tried to take a screenshot, I was prompted to “Share” my screen. This constant interruption quickly became frustrating, especially when I needed to capture multiple screenshots in quick succession.

The Root of the Problem

After some investigation, I discovered that this wasn't actually a Flameshot bug. The issue stems from a unilateral decision made by Gnome developers that affects all third-party screenshot tools[1]. They implemented a new security measure that requires users to explicitly share their screen for each capture attempt.

The Impact on Users

This change has significant implications for productivity:

• Workflow disruption: The constant prompts break concentration and slow down tasks.
• Inconsistent user experience: Gnome's own screenshot tool is whitelisted, creating an unfair advantage.
• Limited options: Users who prefer alternative tools like Flameshot are penalized.

Community Reaction

I'm not alone in my frustration. Many users have voiced their concerns about this change:

• On GitHub: Multiple issues have been opened discussing the problem.
• On Gnome's GitLab: Developers and users alike have debated the merits of this decision.

What Can Be Done?

Unfortunately, there's little that Flameshot's developers can do to address this issue directly. The ball is in Gnome's court. If you're as frustrated as I am, consider:

1. Voicing your concerns on Gnome's issue trackers.
2. Exploring alternative desktop environments that don't implement this restriction.
3. Using Flameshot on X11 instead of Wayland (if possible in your setup).

Looking Forward

While I understand the security considerations behind this change, I hope Gnome developers will reconsider their approach. A more balanced solution that respects both security and usability would be ideal for all users, regardless of their preferred screenshot tool.

In the meantime, I'll be keeping a close eye on developments and exploring workarounds to maintain my productivity while using Flameshot on Gnome Wayland.
