Hi Alf, neolib is an independent project with no neoGFX dependencies; unlike neoGFX it also has a permissive licence. /Flibble -- "Snakes didn't evolve, instead talking snakes with legs changed into snakes." - Rick C.

And not only bookkeeping. :-) I recently worked for a bank with about 500 COBOL developers doing all the heavy data lifting. Even when you have a smart phone app accessing a server written in Java, the Java code will send all the transactions to the COBOL back end for validation and data base accesses. This doesn't show up in the Tiobe index, because it is all closed source and the 50 year old developers don't ask COBOL questions on any net forum. :-) Bo Persson |

Delphi is for small one shot projects... usefull for single developer when she wants to deliver fast. Used C++ Builder in 90es.

In some parts of Argentina, Delphi is still relevant, but of course, not like years ago. It's a very good product IMHO, but it's proprietary, very expensive and the cool kids today use web interfaces even in the desktop land :-O Regards Cholo Lennon Bs.As. ARG |

Bonita specifically started the thread "Task for Amine", in order to insult the guy, and start a "fight" thread. We all know Amine makes annoying posts, but that is because he is clearly not quite right in the head. But Bonita's posts recently are bring a whole new level of nastiness into it. It is really unpleasant. |

C++ isn't an easy language and even if you have been programming for a long time you will hit subtleties again and again. |

Boy, you're manic. Seek advice from a doctor. If you have a desire to be needed by other developers and to get their esteem orient yourself according their needs. Providing Delphi-libraries today will be as successful as selling ice in the antarctic. |

This project of mine works with: GNU C++ and Visual C++ and C++Builder and with both Windows and Linux. My Parallel C++ Conjugate Gradient Linear System Solver Library that scales very well version 1.76 is here.. Author: Amine Moulay Ramdane Description: This library contains a Parallel implementation of Conjugate Gradient Dense Linear System Solver library that is NUMA-aware and cache-aware that scales very well, and it contains also a Parallel implementation of Conjugate Gradient Sparse Linear System Solver library that is cache-aware that scales very well. Sparse linear system solvers are ubiquitous in high performance computing (HPC) and often are the most computational intensive parts in scientific computing codes. A few of the many applications relying on sparse linear solvers include fusion energy simulation, space weather simulation, climate modeling, and environmental modeling, and finite element method, and large-scale reservoir simulations to enhance oil recovery by the oil and gas industry. Conjugate Gradient is known to converge to the exact solution in n steps for a matrix of size n, and was historically first seen as a direct method because of this. However, after a while people figured out that it works really well if you just stop the iteration much earlier - often you will get a very good approximation after much fewer than n steps. In fact, we can analyze how fast Conjugate gradient converges. The end result is that Conjugate gradient is used as an iterative method for large linear systems today. Please download the zip file and read the readme file inside the zip to know how to use it. You can download it from: https://sites.google.com/site/scalable68/scalable-parallel-c-conjugate-gradient-linear-system-solver-library Language: GNU C++ and Visual C++ and C++Builder Operating Systems: Windows, Linux, Unix and Mac OS X on (x86) Thank you, Amine Moulay Ramdane. |

Providing Delphi-libraries > today will be as successful as selling ice in the antarctic. Hello, You have to understand my spirit.. I want to make Delphi much more powerful by inventing scalable algorithms and implementing them in Delphi.. Here is one of my scalable algorithm and its implementation, read about it here: https://sites.google.com/site/scalable68/scalable-reference-counting-with-efficient-support-for-weak-references Thank you, Amine Moulay Ramdane. |

I think here is the problem with Rust: I will reformulate more smartly what about race conditions detection in Rust, so read it carefully: You can think of the borrow checker of Rust as a validator for a locking system: immutable references are shared read locks and mutable references are exclusive write locks. Under this mental model, accessing data via two independent write locks is not a safe thing to do, and modifying data via a write lock while there are readers alive is not safe either. So as you are noticing that the "mutable" references in Rust follow the Read-Write Lock pattern, so this is not good, because it is not like more fine-grained parallelism that permits us to run the writes in "parallel" and gain more performance from parallelizing the writes.
