Zitat: In this post we are going to explore the main data structures found in almost any cryptocurrency based on the blockchain technology.

Zitat: Für die X11-Komponenten des KDE-Windowmanagers KWin wird es künftig keine neuen Funktionen geben. KWin-Entwickler Martin Flöser kündigte den damit letzten Feature Freeze an. Gepflegt werden soll der Code aber weiterhin.

Zitat: Thinking about how we read and write code not only improves the quality of that code, it also increases our own and others ease of mind when working with it. It can improve the fluency of your work and free your mind to think about real important stuff.

Zitat: PHP Sessions are often taken for granted. A session is a magic array which persists across page loads and holds user-specific data. It’s a fantastic and integral part of most web applications. But when misused, sessions can cause substantial security holes, performance and scalability problems, and data corruption. A deep understanding of sessions is vital to production web development in PHP.

Zitat: One of my resolutions for 2017 was to redesign my blog. One week before the new year I faced myself with the challenge and thought to myself if this was still doable. Somehow I managed it and here it is. In this article I will explain the process and show you how I redesigned the blog with Tailwind CSS and moved it from Jekyll to Laravel with keeping almost the same performance.

Zitat: Phing is a great tool (I'm using it as well), but in this article, I want to show you that some projects may not need it. Composer contains a powerful feature called "Scripts", which can be used to create a simple build script.

Zitat: The @extends Blade directive accepts a second (undocumented) parameter to pass data to the parent layout.

Zitat: mb_substr() is a very expensive operation due to how UTF-8 strings work: encoded characters have variable lengths between 8 and 32 bits. If you want the 5th character you can't simply look at the fifth byte (like with ASCII strings) because you don't know how many bytes the preceeding 4 characters are using - you always need to count from the beginning of the string. So everytime my code wanted to know the character at position x it would use mb_substr() to read each individual character from the start of the string through position x.

Zitat: Sicherheitslücken in fast allen modernen Prozessoren verunsichern seit der vergangenen Woche Privatanwender und Administratoren. Wir erklären, was Nutzer derzeit unternehmen sollten und wo noch Unklarheit besteht. Dabei konzentrieren wir uns auf Desktop- und Server-Systeme.

Zitat: Auch nach dem Ende der 7-Tages-Frist werden ARD, ZDF und Co weiterhin depublizieren, weil Rechte für längere Verweildauern fehlen. Aber selbst wo die Rechte vorhanden wären, drohen Löschungen in Mediatheken und YouTube-Kanälen solange die grundsätzliche Depublizierungspflicht fortbesteht.

• One line conditionals
• One line filtering lists
• One line sum list values

Zitat: Using the model’s touch() method, we can update an article’s updated_at column

Zitat: When writing code, you should, of course, keep all the best practices in mind that you can think of. But there is no need to consider them all at the same time. Make a balance between code quality and speed of development, applying the best practices that apply to the situation you're in at that point. The best practices are best practices for a majority of the situations, but they are generalized so as to apply to a majority of the situations. This also means they may not apply to your situation, or there may be more important things you should weigh in.

Zitat: Psalm is good at finding potential issues in large codebases, but once found, it can be something of a gargantuan task to fix all the issues. This release introduces Psalter, designed to fix issues that Psalm finds.

Zitat: Second, in my opinion maintainers should make every effort to support the lowest currently supported version of PHP, through providing support for older packages. This support need not be comprehensive; it can simply be security-only fixes. The key here is that package maintainers not abandon users of the package who are using it on older (but still supported versions) of PHP.

Zitat: Mit der VR-Brille wenden deutsche Forscher vom Universitätsklinikum Hamburg-Eppendorf ein bekanntes Experiment der Verhaltensforschung erstmals unter Laborbedingungen auf den Menschen an.

Zitat: In fact, the bizarre confluence of so many disparate researchers making the same discovery of two-decade-old vulnerabilities raises the question of who else might have found the attacks before them—and who might have secretly used them for spying, potentially for years, before this week's revelations and the flood of software fixes from practically every major tech firm that have rushed to contain the threat.

Zitat: If you stay too long on one form or get away from your computer, and then go back to fill it in – you may get a TokenMismatchException, because the CSRF token won’t be the same. It kinda makes sense, but the problem I recently discovered that it does the same for logout (which is also a form). And that’s pretty silly, so how to avoid it?

Zitat: Die Forscher sorgen nun dafür, dass die Spekulation bei einem bestimmten Befehl (bedingter oder indirekter Sprung, Exception etc) immer schief geht und dass die Zeit, bis der Prozessor die fehlerhafte Spekulation erkennt, möglichst lang ist. Dann ist genügend Zeit (zum Teil 100 Takte und mehr), um zahlreiche nachfolgende Befehle „transient“ auszuführen. Das heißt, die transienten Befehle werden nur spekulativ mit internen Registern und nie wirklich mit den Architekturregistern ausgeführt, sie können also auch nie eine Exception generieren, egal welchen Unsinn sie anstellen.

Zitat: Das Problem in der PSP-Firmware ist ein Buffer Overflow, anhand dessen sich im Platform Security Processor beliebiger Code ausführen lässt. Um die Sicherheitslücke auszunutzen sind anscheinend Administrator- beziehungsweise Root-Rechte erforderlich.
