[18:18] schestowitz[TR][18:18] schestowitz[TR]Preemption lies at the core of real-time Linux. Preemption consists in temporarily interrupting the current thread of execution so that a higher-priority event can be processed in a timely manner. Increasing the preemptible code surface within the Linux kernel dramatically improves the capability to provide a deterministic response time to an external event. Lets discuss the princi [18:18] schestowitz[TR] ples behind preemption in greater detail.

[18:20] schestowitz[TR][18:20] schestowitz[TR]Undeniably, in computers and operating systems this is a fact. However, universal privilege used to be the norm, and restricting actions was a concept that wasnt part of the vocabulary. Today, this idea is a must. Our machines are constantly interacting with the external world, exchanging information, and deliberately fetching and executing pieces of code and software from servers hosted [18:20] schestowitz[TR] in places we might never visit. Meanwhile, we trust and intertwine our lives with these machines.

[18:55] schestowitz[TR][18:55] schestowitz[TR]U.S. Senators Amy Klobuchar (D-MN) and Mike Lee (R-UT) are calling for the Department of Justice to continue investigating Ticketmaster and Live Nations anti-competitive practices.
[18:55] schestowitz[TR]In a bipartisan letter after the recent Senate Judiciary Committee hearings, both Senators urge the DOJ to take action. We have long been concerned about the state of competition in Americas ticketing industry, especially with the power and reach of Live Nation and its wholly-owned subsidiary, Ticketmaster. For too long, Live Nation and Ticketmaster have wielded monopoly power anti-competitiv [18:55] schestowitz[TR] ely, harming fans and artists alike, the Senators write to Assistant Attorney General for the Antitrust Division of the DOJ, Johnathan Kanter.

[19:14] schestowitz[TR][19:14] schestowitz[TR]This is a list of reviews of System76 laptop and desktop computers by different authors for five years from 2009 to 2014. We managed to collect reviews of several System76 models ranging from Serval, Galago, Gazelle, Lemur, Pangolin, to Bonobo Pro with various Intel technologies from Core 2 Duo to generations of i7 with various graphics processors from HD Graphics, Iris Pro to NVIDIA GTX Mo [19:14] schestowitz[TR] bile. We summarized every review by its specifications, battery hour, and the author's conclusion and linked to every original website so you can read further. We hope this really helps everyone considering then purchasing GNU/Linux-preinstalled branded computers suitable for them. Please read on and look forward for the next collection too. Happy reading!

[19:20] schestowitz[TR][19:20] schestowitz[TR]LibreOffice is a cross-platform, free libre open source software (FOSS) office suite from Germany developed by worldwide community under stewardship of a non-profit organization. It was originally developed from OpenOffice.org in 2010, first released in 2011 and the latest version 7.5 released in 2023. It is consisted of six applications namely Base (database), Calc (spreadsheet), Draw (illustrator [19:20] schestowitz[TR] ), Impress (presentation), Math (equation editor), and Writer (word processor). It is mostly viewed as an alternative to Microsoft Office or Google Docs. It is the de facto office suite on all GNU/Linux operating systems especially Ubuntu. Its website is https://libreoffice.org.

[19:26] schestowitz[TR][19:26] schestowitz[TR]How would you test PDF generation?
[19:26] schestowitz[TR]This turns out to be unexpectedly difficult because you need to check that the files are both syntactically and semantically valid. The former could be tested with existing PDF validators and converters but the latter is more difficult.
[19:26] schestowitz[TR]If you, say, try to render a red square, the end result should be that the PDF command stream has two commands, a re command and an f command. That could be verified simply by grepping the command stream with some regexps. It would not be very useful, though, as there is no guarantee that those commands actually produce a red square in the output document. There are dozens of ways to make t [19:26] schestowitz[TR] he output stream not produce a red square in the intended location without breaking file "validity" in any way.
