Rezension: β€žMeteorologie fΓΌr Segelfliegerβ€œ von Henry Blum Die Gemeinde der Segelflieger ist durchaus ein merkwΓΌrdiges Volk. Allein die Gewohnheit, an freien Tagen von frΓΌh bis spΓ€t in engen Kapseln durch die Luft zu tanzen, deutet auf eine ausgeprΓ€gte Ver…

Es gibt ein Buch von Henry Blum, dass dieses Fakt auch fΓΌr die Bildung von Thermik einbindet: flugfieber.wordpress.com/rezension-me...

Sicherlich auch ein Zusammenhang fΓΌr das feucht- und trocken-adiabatische Auf/Absteigen bei FΓΆhnwetterlagen in den Alpen.

I really like rdiff-backup for creating incremental backups with rsync.

vis.social vis.social is a community for creative people, especially anyone in SciArt, SciComm, data, visualization, creative coding, and related arts and research. English is the shared language.

Is it vis.social?

Die meisten Landkreise haben momentan eine positive Tendenz. Und dies sogar in den RKI-Daten, die die wahre Anzahl wohl deutlich unterschΓ€tzen. coronavis.dbvis.de/de/overview/...

I completely agree. Safety first.
It happened on push back but instead of fixing it we had to get to a new plane. Now it's just a funny anecdote :)

I had a flight delayed because the plastic emergency exit sign fell off. We had to get a new plane.

Yes: for personal scripts, helper tools, etc.

No: public-facing tools/apps & services require much more than just somewhat "working code". Many have been burnt already by insecure apps, leaking API keys & secrets, and hacked databases.

I switched to Brave browser. However, their default privacy settings sometimes cause issues, but overall, I like it so far.

I really beg datavis researchers to start engaging with this.

The role of the chart here is to provide a cover of objectivity.

It’s reifying the entire fucking opinion section into a 2d space to lens it some Cartesian legitimacy or something equally dark. So, so gross.

Defense Against Dishonest Charts This is a guide to protect ourselves and to preserve what is good about turning data into visual things.

Dishonest charts are coming from all directions, and they're only going to hit harder. Unless we push back. So, an interactive guide: Defense Against Dishonest Charts flowingdata.com/projects/dis...

Dear OU Community,

 

I write to acknowledge the questions and concerns raised by recent federal executive orders and communications from the Executive Branch related to federal assistance and grants that impact the university.

 

While the full extent of changes and their implications are unfolding quickly across the OU enterprise, I want to reassure you that we are closely monitoring developments and evaluating their potential impact on our university. As indication of this rapid pace, the U.S. Department of Education has just confirmed today that funding for federal student loans and Pell Grants will continue without interruption, and the university’s Student Financial Center will continue to process federal aid.

 

The university will continue to gather all available information and review as quickly as possible to best understand its implications and next steps, and we remain committed to sharing this information at every level of the university as quickly as possible. A web page with FAQs also is being developed for sharing of information in real time.

 

As the state’s premier research university, we are committed to serving the needs of our students and conducting research that benefits us all. We will continue to engage with all state and federal agencies and key stakeholders to gain clarity on the scope and impact of these initial executive orders and the Executive Branch’s directives.

 

Thank you in advance for your patience as we navigate these early days. We appreciate your continued dedication as we move forward through this period of transition, and we remain unwavering in our commitment to the important work we do together.

 

Sincerely,

 

Joseph Harroz, Jr.

President
