KDE 2.0 Development, Which Is Directly Supported
23 8911 CH18 10/16/00 1:44 PM Page 401 The KDevelop IDE: The CHAPTER Integrated Development Environment for KDE by Ralf Nolden 18 IN THIS CHAPTER • General Issues 402 • Creating KDE 2.0 Applications 409 • Getting Started with the KDE 2.0 API 413 • The Classbrowser and Your Project 416 • The File Viewers—The Windows to Your Project Files 419 • The KDevelop Debugger 421 • KDevelop 2.0—A Preview 425 23 8911 CH18 10/16/00 1:44 PM Page 402 Developer Tools and Support 402 PART IV Although developing applications under UNIX systems can be a lot of fun, until now the pro- grammer was lacking a comfortable environment that takes away the usual standard activities that have to be done over and over in the process of programming. The KDevelop IDE closes this gap and makes it a joy to work within a complete, integrated development environment, combining the use of the GNU standard development tools such as the g++ compiler and the gdb debugger with the advantages of a GUI-based environment that automates all standard actions and allows the developer to concentrate on the work of writing software instead of managing command-line tools. It also offers direct and quick access to source files and docu- mentation. KDevelop primarily aims to provide the best means to rapidly set up and write KDE software; it also supports extended features such as GUI designing and translation in con- junction with other tools available especially for KDE development. The KDevelop IDE itself is published under the GNU Public License (GPL), like KDE, and is therefore publicly avail- able at no cost—including its source code—and it may be used both for free and for commer- cial development. -

Resurrect Your Old PC
Resurrect your old PCs Resurrect your old PC Nostalgic for your old beige boxes? Don’t let them gather dust! Proprietary OSes force users to upgrade hardware much sooner than necessary: Neil Bothwick highlights some great ways to make your pensioned-off PCs earn their keep. ardware performance is constantly improving, and it is only natural to want the best, so we upgrade our H system from time to time and leave the old ones behind, considering them obsolete. But you don’t usually need the latest and greatest, it was only a few years ago that people were running perfectly usable systems on 500MHz CPUs and drooling over the prospect that a 1GHz CPU might actually be available quite soon. I can imagine someone writing a similar article, ten years from now, about what to do with that slow, old 4GHz eight-core system that is now gathering dust. That’s what we aim to do here, show you how you can put that old hardware to good use instead of consigning it to the scrapheap. So what are we talking about when we say older computers? The sort of spec that was popular around the turn of the century. OK, while that may be true, it does make it seem like we are talking about really old hardware. A typical entry-level machine from six or seven years ago would have had something like an 800MHz processor, Pentium 3 or similar, 128MB of RAM and a 20- 30GB hard disk. The test rig used for testing most of the software we will discuss is actually slightly lower spec, it has a 700MHz Celeron processor, because that’s what I found in the pile of computer gear I never throw away in my loft, right next to my faithful old – but non-functioning – Amiga 4000. -

For the human brain, sequences like -> , <= or := are single logical tokens, even if they take two or three characters on the screen. Your eye spends a non-zero amount of energy to scan, parse and join multiple characters into a single logical one. Ideally, all programming languages should be designed with full-fledged Unicode symbols for operators, but that’s not the case yet. Solution Download v1.203 · How to install · News & updates Fira Code is an extension of the Fira Mono font containing a set of ligatures for common programming multi-character combinations. -

Github: a Case Study of Linux/BSD Perceptions from Microsoft's

This acquisition was not community has different attitudes towards GitHub is the idea without controversy, as it is well-known that the free software communities includes not only the ability to use software freely, of ‘forking’ so far, as it it is considered as a danger to FLOSS but also the libre nature in Open Source Software. In this study, development [10]. our aim is to explore these perceptions in FLOSS developers. We In this paper, we report on how external events such as conducted a survey that covered traditional FLOSS source Linux, acquisition of the open source platform by a closed source and BSD communities and received 246 developer responses. organization triggers a FLOSS developers such the Linux/ The results of the survey confirm that the free community did trigger some communities to move away from GitHub and raised BSD Free Software communities. discussions into free and open software on the GitHub platform.

Product teams and application developers are more likely to 23 choose Apertis if it offers flows for building, shipping, and updating applications 24 that are convenient, cheap, and that require low maintenance. 25 To reach that goal, a key guideline is to closely align to upstream solutions 26 that address those needs and integrate them into Apertis, to provide to appli- 27 cation authors a framework that is made of proven, stable, complete, and well 28 documented components. 29 The cornerstone of this new approach is the adoption of Flatpak, the modern 30 application system already officially supported on more than 20 Linux distribu- 1 31 tions , including Ubuntu, Fedora, Red Hat Enterprise, Alpine, Arch, Debian, 32 ChromeOS, and Raspian.
