Nokia's N900: Desktop Linux without the desk.

Filed under
Linux

In a previous post I wrote about how easy it was to use Nokia’s N900 out of the box. Today I’ll give you just a taste of what’s possible when you unlock the its full potential as handheld Linux computer.

All you have to do to get started is activate the Extras-devel software catalog…

Sculpt OS release 20.08

  • Sculpt OS release 20.08

    The new version of Sculpt OS is based on the latest Genode release 20.08. In particular, it incorporates the redesigned GUI stack to the benefit of quicker boot times, improved interactive responsiveness, and better pixel output quality. It also removes the last traces of the noux runtime. Fortunately, these massive under-the-hood changes do not disrupt the user-visible surface of Sculpt. Most users will feel right at home. Upon closer inspection, there are couple of new features to appreciate. The CPU-affinity of each component can now be restricted interactively by the user, components can be easily restarted via a click on a button, font-size changes have an immediate effect now, and the VESA driver (used when running Sculpt in a virtual machine) can dynamically change the screen resolution.

  • Sculpt OS 20.08 Released With Redesigned GUI Stack

    Building off the recent Genode OS 20.08 operating system framework release is now Sculpt OS 20.08 as the open-source project's general purpose operating system attempt. Sculpt OS 20.08 pulls in the notable Genode 20.08 changes like the redesigned GUI stack with better responsiveness and other benefits. It also includes the ability to run the Falk web browser as the first Chromium-based browser on Genode/Sculpt. Sculpt OS is Genode's effort around creating a general purpose OS but for right now is still largely limited to developers, hobbyists, and those wishing to tinker around with new operating systems.

  • Python : 10 Ways to Filter Pandas DataFrame

    In this article, we will cover various methods to filter pandas dataframe in Python. Data Filtering is one of the most frequent data manipulation operation. It is similar to WHERE clause in SQL or you must have used filter in MS Excel for selecting specific rows based on some conditions. In terms of speed, python has an efficient way to perform filtering and aggregation. It has an excellent package called pandas for data wrangling tasks. Pandas has been built on top of numpy package which was written in C language which is a low level language. Hence data manipulation using pandas package is fast and smart way to handle big sized datasets.

  • Top GUI Frameworks that is every Python Developer's Favorite

    Python is one of the most popular and widely known programming languages that is a favorite in the developer community. Its advanced libraries and file extensions enable developers to build state-of-the-art tools for real-world problems, or simply design a GUI (Graphic User Interface). GUI plays an essential role in the computer world as it makes human-machine interaction easier. Python offers a diverse range of options for GUI frameworks. Some of these frameworks are more preferred by the developers to build both .apk and .exe applications. Moreover, its GUI toolkits include TK, GTK, QT, and wxWidgets, which come with more features than other platform-specific kits. Though the Python wiki on GUI programming lists on 30 cross-platform frameworks, we have selected our top 4 picks. They are: Kivy: It an open-source Python library for the rapid development of applications that makes use of innovative user interfaces, such as multi-touch apps. This liberal MIT-licensed Kivy is based on OpenGL ES 2 and includes native multi-touch for each platform. It is an event-driven framework based around the main loop, making it very suitable for game development. It supports multiple platforms, namely, Windows, MacOSX, Linux, Android-iOS, and Raspberry Pi. Unlike QtCreator, Kivy doesn’t have a visual layout program, but it uses its own design language to help you associate UI layout with code objects.

  • How to use Strcpy() in C language?

    In this article, we are going to learn about the strcpy() function in the C programming language. The strcpy() function is a very popular standard library function to perform the string copy operation in the C programming language. There are several standard header files in C programming language to perform standard operations. The “string.h” is one of such header files, which provides several standard library functions to perform string operations. The “strcpy()” function is one of the library functions provided by “string.h”.

  • How to Use C++ Vector

    An array is a series of same object types in consecutive memory locations. An array cannot increase ore reduce in length. A vector is like an array, but its length can be increased or reduced. A vector, therefore, has many more operations than an array. C++ has many libraries, all of which form the C++ Standard Library. One of these libraries is the container library. A container is a collection of objects, and certain operations can be performed on the collection. C++ containers can be grouped into two sets: sequence containers and associative containers. Sequence containers are vector, array (not the same array discussed previously), deque, forward_list, and list. These are different collections (array-like data structures), and each offers distinct trade-offs. Any programmer should know how to decide whether to use a vector, an array, a deque, a forward_list, or a list. When a programmer needs a structure that requires more operations than those associated with an ordinary array, the ordinary array should not be used. If the task involves frequent insertions and deletions in the middle of the sequence, then a list or forward_list should be used. If the task involves frequent insertions and deletions in the beginning or end of a sequence, then a deque should be used. A vector should be used when these kinds of operations are not required.

  • How to Use isalpha() in C Language

    There are several standard library header files in the C programming language used to perform various standard operations. The “ctype.h” is one such header file, and the “isalpha()” function is one of the library functions provided by “ctype.h.” The isalpha() library function is used to identify whether a character is an alphabet. In this article, you will learn about the isalpha() library function in C language.
