45 Amazing Free Fantasy and Sci-fi Art Wallpapers | Graphic Desi I’m always fascinated by fantasy and science fiction illustrations. I am not a sci-fi and fantasy novel fan, but I always find myself staring in awe and admiration at Asimov science fiction book covers and artworks by known fantasy and sci-fi masters like Fred Gambino, Chris Moore, David Mattingly, Boris Vallejo and Luis Royo. Fantasy and sci-fi artworks are very inspiring even for non fantasy art fans. You can’t help but admire those magical and sometimes muted colors, the softness and sometimes graininess texture in comparison to contemporary flat colors and harsh lines of regular artworks and designs. Also there’s more calm yet disturbing, and mysterious feeling to them than the harsh, straight-up, and fixated stuff we see a lot everyday. It’s really beyond our world and beyond words to describe. 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. 15. 16. 17. 18. 19. 20. 21. 22. 23. 24. 25. 26. 27. 28. 29. 30. 31. 32. 33. 34. 35. 36. 37. 38. 39. 40. 41. 42. 43. 44.
Beautiful Word Clouds BeginnersGuide New to programming? Python is free and easy to learn if you know where to start! This guide will help you to get started quickly. Chinese Translation/中文版入门 New to Python? Read BeginnersGuide/Overview for a short explanation of what Python is. Getting Python Next, install the Python 3 interpreter on your computer. There are also Python interpreter and IDE bundles available, such as Thonny. At some stage, you'll want to edit and save your program code. Learning Python Next, read a tutorial and try some simple experiments with your new Python interpreter. If you have never programmed before, see BeginnersGuide/NonProgrammers for a list of suitable tutorials. Most tutorials assume that you know how to run a program on your computer. Some sites offer in-browser coding for those who want to learn Python: Print a cheat sheet of the most important Python features and post it to your office wall until you know the basics well.

Optimisation linéaire Un article de Wikipédia, l'encyclopédie libre. Par exemple, le problème à deux variables suivant qui consiste à minimiser la fonction linéaire sous la contrainte d'inégalité affine et les contraintes de positivité des est un problème d'optimisation linéaire. . Plus généralement, un problème d'OL s'écrira donc en notation matricielle de la manière suivante où est l'inconnue, le vecteur des variables réelles à optimiser, et les données sont des vecteurs et et une matrice . doit être entendue composante par composante : pour tout indice , on doit avoir . est donc bien un polyèdre convexe, puisqu'il s'agit de l'intersection des demi-espaces , pour , en nombre fini. Parmi les problèmes d'optimisation avec contraintes d'inégalité, les problèmes linéaires sont simples à résoudre numériquement. itérations pour une formulation du problème voisine de celle donnée ci-dessus. Beaucoup de problèmes de recherche opérationnelle peuvent être exprimés comme des problèmes d'optimisation linéaire. . . On note si et si .

Now comes the tricky part on how to get the rest of the hardware components to fit. Installation completed The HDD and PSU panel were fixed in position with a double-sided self-adhesive tape. Powered ON Up and running Posing You may notice that the bottle cap is sitting on the table top on all these images. HiperLigações Optimizing C and C++ Code Embedded software often runs on processors with limited computation power, thus optimizing the code becomes a necessity. In this article we will explore the following optimization techniques for C and C++ code developed for Real-time and Embedded Systems. Many techniques discussed here have roots in the material we covered in the articles dealing with C to Assembly translation. A good understanding of the following articles will help: Premature optimization is the root of all evil Donald Knuth wrote, "Programmers waste enormous amounts of time thinking about, or worrying about, the speed of noncritical parts of their programs, and these attempts at efficiency actually have a strong negative impact when debugging and maintenance are considered. In general, correctness and readability considerations trump code performance issues for most of your code. Adjust structure sizes to power of two Place case labels in narrow range Place frequent case labels first Splitting a switch statement
H ritage Multiple Plusieurs langages à objets, par exemple C++ et Eiffel, offrent le concept d'héritage multiple. Dans ces langages, une sous-classe peut hériter de deux ou de plusieurs super-classes immédiates. Ceci pose un certain nombre de problèmes non triviaux, aussi bien au niveau de la définition du langage qu'à celui de son implémentation. Le graphe d'héritage d'une application donnée n'a, en général, plus la forme d'un arbre, ou d'une forêt dont les arbres individuels sont issus de classes racines disjointes, mais d'un DAG. La sous-classe D possède deux super-classes immédiates B et C; on remarque de plus qu'elle hérite indirectement de la classe racine A par les deux relations d'héritage distinctes D->B->A et D->C->A. Ceci pose un premier problème au niveau de la définition du langage. Il n'est pas possible de définir des règles de visibilité qui satisfassent ces contraintes dans tous les cas. Exemple: On a, de nouveau le cas du graphe d'héritage en losange vu plus haut. Héritage commun
jQuery: The Write Less, Do More, JavaScript Library Toshiba Develops 1TB SSD That Fits On A Postage Stamp - HotHardw SSDs are still overpriced for most average consumers, but the companies responsible for making them are constantly searching for ways to make them larger (in terms of capacity), smaller (in terms of form factor) and cheaper (in terms of real dollars). Toshiba has their own line of solid state drives right now, but just as the company has innovated in the optical storage department, they're also hoping to innovate in the world of NAND storage. A new partnership between the company and Tokyo's Keio University has led to the creation of a new technology that could allow SSDs up to 1TB in size to be made "with a footprint no larger than a postage stamp." The report states that the two have been able to integrate 128GB NAND Flash chips and a single controller into a stamp-sized form factor.
