Commit-Messages in Git werden oft vernachlässigt. Viele sehen sie lediglich als notwendiges Übel an, um Änderungen zu speichern. Dabei sind aussagekräftige Commit-Messages ein entscheidender Faktor für den Erfolg eines Projekts: Sie sorgen eine gute Nachvollziehbarkeit von Änderungen, eine effiziente Zusammenarbeit im Team und eine schnellere Fehlersuche. Kein Grund, die Commit-Messages automatisch mit Hilfe von KI erstellen zu lassen.
...Der Februar hat manchmal eine ungewöhnlich ansprechende Form im Kalender. Beispielsweise konnte man im Februar 2021 einen solchen Moment zu erleben, einen "perfekt rechteckigen Februar" zu sehen. Dieser seltene Effekt tritt auf, wenn der Februar genau \(28\) Tage hat und der 1. Februar auf einen Montag fällt. Aber wie oft kommt das tatsächlich vor und wie lange muss man auf das nächste Mal warten?
...CSS ist für die meisten von uns immer noch verwirrend: Es hat hunderte schlecht benannte Eigenschaften, von denen jede das Ergebnis auf nicht intuitive Weise beeinflussen kann. Die vertikale Positionierung von Elementen in der Webentwicklung ist tricky und hat in der Vergangenheit oft Kopfzerbrechen bereitet. Doch diese Zeiten sind glücklicherweise vorbei.
...CSS-Übergänge sind eine gute Möglichkeit, Interaktivität zu erzeugen. Es genügt, transition auf den Ausgangszustand eines Elements anzuwenden, und der Browser animiert den Übergang zwischen den beiden Zuständen. Übergänge für intrinsische Elementgrößen wie auto sind jedoch seit Jahrzehnten ein Problem für Webentwickler, und die einzige Möglichkeit bestand darin, die Höhe dynamisch mit JavaScript zu berechnen.
Es gibt kein \(n \in \mathbb{Z}^+\), so dass \(0 < n < 1\).
...Die Physiker George Gamow und Marvin Stern bemerkten im Jahre 1950 ein interessantes Phänomen: Gamow, der ein Büro im ersten Stock eines sechsstöckigen Gebäudes hatte, bemerkte, dass der nächste ankommende Fahrstuhl in fünf von sechs Fällen nach unten fuhr, obwohl er nach oben wollte. Stern, der im fünften Stock arbeitete, beobachtete das Gegenteil.
...Ein Quine-Programm oder Quine ist ein Programm, das beim Ausführen seinen eigenen Quellcode ausgibt. Ein Quine darf nicht „aus sich selbst heraustreten“, indem es beispielsweise den Inhalt der Datei ausdruckt, in der es enthalten ist, oder introspektive Fähigkeiten verwendet, um seine eigene Darstellung auszudrucken. Stattdessen muss es seinen eigenen Quellcode berechnen.
...Mächtige Tools wie logrotate erleichtern die Arbeit bei der Rotation von Log- oder Backup-Dateien erheblich. So werden die Dateien nach einer bestimmten Zeitspanne oder wenn sie eine bestimmte Größe erreichen, rotiert. Wer auf einem entfernten Server dieses Tool nicht zur Verfügung hat und nur remote SSH-Kommandos ausführen kann, kann sich selbst mit einem kleinen Bash-Script behelfen, das alte Dateien löscht und dabei nur einen Request absetzt.
...In der Welt der Zahlen stößt man immer wieder auf überraschende Muster, die sowohl verblüffend als auch erhellend sein können. Eine solche Kuriosität ist das Benford’sche Gesetz, auch bekannt als das Gesetz der ersten Ziffer. Dieses mathematische Phänomen beschreibt die Häufigkeitsverteilung der ersten Ziffern in vielen realen Datensätzen und bietet interessante Einblicke in die Natur von Zahlen, wie sie in unserer Umwelt vorkommen.
...Ich habe zwei Kinder und einen Sohn, der an einem Donnerstag geboren wurde. Wie groß ist die Wahrscheinlichkeit, dass ich eine Tochter habe? Bezeichnen wir die Wochentage mit den Zahlen \(1, 2, … , 7\) mit \(1\ =\) Montag, \(2 =\) Dienstag und so weiter. Jetzt können wir das Ereignis als „am Tag \(n\) wurde ein Junge geboren“ als \(B_n\), und ebenso ähnlich für \(G_n\) definieren.
...Unter der Annahme, dass die Anzahl \(Y\) aller Menschen, die jemals geboren wurden und irgendwann geboren werden, begrenzt ist, sei \(x\) Deine absolute Position vom Beginn der Liste. Dann ist \(0 < \frac{x}{Y} \leq 1\). Wir können nun mit einer Wahrscheinlichkeit von \(95\%\) sagen, dass Du unter den letzten \(95\%\) aller jemals geborenen Menschen bist, also \(0,05 < \frac{x}{Y} \leq 1\) und damit \(Y < \frac{x}{0,05} = \frac{100 \cdot x}{5} = 20 \cdot x\).
