Best Linux Software You’ve made the switch from Windows or Mac OS X, and now you’re looking for applications to install. Or maybe you’re a long-time Linux user who’s keeping an eye out for what’s new. Either way, you’ve come to the right place. You’ve already picked a Linux distro and have settled on a desktop environment. Those are the big choices that determine what software you start with and what will run best on your machine. But now it’s time to delve through your distro’s app repositories to see what’s worth installing. Most of the software below is free and open source. A few require you to download an installer from a website. Browsers Firefox With the new Quantum update, Mozilla has given people reason to check out Firefox again. 9 Reasons to Switch From Chrome to Firefox 9 Reasons to Switch From Chrome to Firefox The days when Chrome was the best browser are long gone. Chrome/Chromium By some measures, Chrome is now the king of the hill. Opera Opera isn’t open source, but it is free. QupZilla Email
You want to create a directory Challenge You want to create a new directory Solution Explanation Creating a directory is another task that is handled by the powerful and flexible file type. You can use a number of parameters from the file type to control the directories properties, such as the owner, group and mode (permissions). It's also worth noting that puppet will not create missing parent directories. See also Making directory trees Linux Directory Structure (File System Structure) Explained with Examples by Ramesh Natarajan on September 8, 2010 Have you wondered why certain programs are located under /bin, or /sbin, or /usr/bin, or /usr/sbin? For example, less command is located under /usr/bin directory. Why not /bin, or /sbin, or /usr/sbin? What is the different between all these directories? In this article, let us review the Linux filesystem structures and understand the meaning of individual high-level directories. 1. / – Root Every single file and directory starts from the root directory.Only root user has write privilege under this directory.Please note that /root is root user’s home directory, which is not same as /. 2. Contains binary executables.Common linux commands you need to use in single-user modes are located under this directory.Commands used by all the users of the system are located here.For example: ps, ls, ping, grep, cp. 3. 4. 5. Contains device files.These include terminal devices, usb, or any device attached to the system.For example: /dev/tty1, /dev/usbmon0 6. 7. 8. 9.
מה זה לוגריתמים ובשביל מה זה טוב? | לא מדויק מבין כל המושגים במתמטיקה שנלמדים בבית הספר, לוגריתמים הם כנראה המושג שנשכח הכי בקלות והכי פחות ברור בשביל מה הוא טוב, בעצם. זה כמובן חבל מאוד כי זה מושג מגניב מאוד (וגם שימושי, אבל לא בחיי היום יום שלנו ואני לא אנסה לטעון אחרת) והוא גם לא קשה כל כך להבנה. אני אתחיל מלהסביר מה זה בעצם, ואז נדבר על הבשביל-מה-זה-טוב. התשובה הקצרה היא “לוגריתם זו הפעולה ההפוכה לחזקה כמו שחיסור הוא הפעולה ההפוכה לחיבור וחילוק הוא הפעולה ההפוכה לכפל” אבל העלילה מסתבכת כבר בשלב הזה, כי יש שתי פעולות הפוכות לחזקה ששונות אחת מהשניה מאוד, כי בניגוד לחיבור וכפל, חזקה היא לא פעולה סימטרית. אני מניח שאנחנו מכירים חיבור - זו נקודת התחלה לא רעה. עכשיו נעבור אל פעולת הכפל. אחרי כפל, הפעולה הבאה שאפשר לדבר עליה היא חזקה. וכאן הסיפור מתחיל להסתבך. בניגוד לחיבור וכפל, חוק החילוף לא מתקיים עבור חזקות. אם כן, העלאה בחזקה היא פעולה שכוללת שני “קלטים” שונים. בואו נראה דוגמא קונקרטית. באופן דומה אפשר לדבר על העלאה בחזקות גבוהות יותר: f(x)=xnf(x)=xn עבור nn טבעי כלשהו. עכשיו, סוף כל סוף, אנחנו מגיעים אל לוגריתמים. עכשיו, לתעלול!

The ‘Evolution’ ImageAI3:::Adaptive InformationAI3:::Adaptive Information Isn’t this picture cool?!? I first encountered this image on Christopher Allen’s Life with Alacrity Web site more than 15 years ago in 2005. In doing some investigation on Google images, you can also find it by searching under images for evolution.jpg. I have not been able to find the original artist or copyright for this image. If someone knows who I should be attributing, please let me know and I will gladly do so. You should know that I have significantly cleaned up the original, giving it a clean background, removing extraneous pixels, and generally sharpening it up (plus some steganography). However, if you are the original artist and you encounter my use of this image without attribution, please accept my sincere apologies for having done so and my thanks for capturing so much.

An API key is a simple encrypted string that identifies an application without any principal. They are useful for accessing public data anonymously, and are used to associate API requests with your project for quota and billing. To learn more about authenticating to Google Cloud APIs and to determine the best authentication strategy for common scenarios, see Authentication overview.

Where Is the Science in Computer Science? | October 2012 By Vinton G. Cerf Communications of the ACM, October 2012, Vol. 55 No. 10, Page 5 10.1145/2347736.2347737Comments (16) We are all members of the Association for Computing Machinery. Sounds sort of electromechanical doesn't it? In the physical world, science is largely about models, measurement, predictions, and validation. That software is an artifact seems obvious. When we write a piece of software, do we have the ability to predict how many mistakes we have made (that is, bugs)? The richness of our field has only grown in the 65 years of our existence as an organization. As a group of professionals devoted to the evolution, understanding, and application of software and hardware to the myriad problems, opportunities, and activities of modern society, we have a responsibility to pursue the science in computer science.
