SoloCodigo

gente del foro, necesito adiestrarme en OpenCV, para mi proyecto final de carrera.

me gustaria saber si ustedes saben de donde puedo conseguir manuales, tutoriales y lirbos de OpenCV, si ustedes me los pueden pasar por internet o i saben de donde los puedo bajar, y de ultima , en el peor de  los casos... COMPRAR.

saludos a todos

primero , creo que no estas utilizando completamente el lenguaje C, mucho menos las librerias estandar de que trae el compilador.

segundo, NO UTILIZES GOTO .... NO NO NO NO, NO USES GOTO POR FAVOR, es la peor practica de un programador, no solo porque no es estructurado, el codigo que genera, es ineficiente.


las librerias estandar de C te brindan funciones como isdigit, o , isletter, etc etc etc, por lo que veo estas usando alguna version de BORLAND, cuya caracteristica principal , es la ayuda que traen sus productos, te sugiero que busques en la ayuda, en todo caso si no sabes que hacer despues te tiro el algoritmo, y si no te sale con el algoritmo, te paso el codigo,

es muy simple, sencillo, y legible.

intentalo, la satisfaccion de hacerlo por uno propio es impagable

mas facil aun:

system("explorer http://www.tuweb.com/loquesea.php");


por ejemplo

osea la respuesta es SI, no le vas a poner escritorio 3D a un 486.

y la pregunta era como reciclar el PC, ahi tiene, lo puede convertir tranquilamente en un servidor web, de archivos FTP, etc. , usando LINUX nada mas y nada menos, a eso me referia.

y deje ahi una distro con interfaz grafica, con editores de texto, compilador,panel de control,  y varias herramientas de consola, etc.

espero les sirva a alguien.

tambien puede usar la PC como nodo de un cluster, con lo cual, va anecesitar menos recursos aun, y en algunos casos, le puede llegar a faltar disco duro, y todavia sirve para ese fin de nodo de un cluster.

FEATHER LINUX:

1. Absolute Linux
Absolute Linux is a light-weight modification of Slackware Linux. It includes several utilities that make configuration and maintenance easier and it has many common desktop and Internet applications installed and configured with tight integration of menus, applications and MIME types. Absolute Linux uses IceWM and ROX for its window and file managers.

2. ANTEMIUM Linux
ANTEMIUM Linux is a French live CD distribution designed for desktops, and especially for older computers with only 64MB of RAM. The desktop environment is IceWM.

3. AUSTRUMI
AUSTRUMI is a business card size (50MB) bootable live CD Linux distribution. It is based on Slackware Linux with initialisation scripts borrowed from the Blin project.

4. BeatrIX Linux
BeatrIX Linux is a compact (less than 200MB) operating system aimed at both office and home users who want something simpler, safer and superior to Microsoft Windows, and that will run on just about any IBM-compatible PC made in the past 10 years. It runs as a live CD or it can be installed to hard drive.

5. Core GNU/Linux
Core is designed and constructed around one simple philosophy: to be the absolute minimum of what is required for a Linux operating system. Core is designed to be the basis for a larger, more complete operating system constructed by the end user. It contains only what is necessary to boot into Linux and download, compile and install other software packages.

6. Damn Small Linux
Damn Small Linux is a business card size (50MB) live CD Linux distribution. Despite its minuscule size it strives to have a functional and easy to use desktop. Damn Small Linux has a nearly complete desktop, including XMMS (MP3, and MPEG), FTP client, links-hacked web browser, spreadsheet, email, spellcheck (US English), a word-processor, three editors (Nedit, nVi, Zile [emacs clone]), Xpdf, Worker (file manager), Naim (AIM, ICQ, IRC), VNCviwer, SSH/SCP server and client, DHCP client, PPP, PPPoE, a web server, calculator, Fluxbox window manager, system monitoring apps, USB support, and soon it will have PCMCIA support as well. If you like Damn Small Linux you can install it on your hard drive. Because all the applications are small and light it makes a very good choice for older hardware.

7. DeLi Linux
DeLi Linux is a Linux distribution for old computers, from 486 to Pentium MMX 166 or so. It's focused on desktop usage. It includes email clients, a graphical Web browser, an office package with word processor and spreadsheet, etc. A full install, including XFree86 and development tools, needs no more than 300 MB of harddisk space.

8. Feather Linux
Feather Linux is a Linux distribution which runs completely off a CD or a USB pendrive and takes up under 128MB of space. It is a Knoppix remaster (based on Debian), and tries to include software which most people would use every day on their desktop.

9. Fluxbuntu Linux
Fluxbuntu is a light-weight, standards-compliant, Ubuntu-based Linux distribution featuring the Fluxbox window manager. The project's primary goal is to develop an operating system that would run on a wide range of mobile devices and computers, both low-end and high-end.

10. LinuxConsole
LinuxConsole is an independently developed Linux live CD with different editions designed for desktops, servers, gaming consoles, and old computers. Its primary characteristics are easy installation, extensive choice of software in the form of modules, and excellent hardware detection.

11. Luit Linux
Luit Linux is a small bootable live CD distribution based on KNOPPIX and Damn Small Linux. A small compact live distribution with tools and applications for day to day needs, without compromising on its look and feel and ease of use.

12. MEPIS Linux
MEPIS Linux is a Debian-based desktop Linux distribution designed for both personal and business purposes. It includes cutting-edge features such as a live, installation and recovery CD, automatic hardware configuration, NTFS partition resizing, ACPI power management, WiFi support, anti-aliased TrueType fonts, a personal firewall, KDE, and much more.

13. Neat-GNU/Linux
Neat-GNU/Linux is going to be like any other GNU/Linux distribution with a couple of differences, the most notable is the installation procedure, but also by keeping the number of packages at a minimum, hence the name; Neat. The installation is not done by copying precompiled packages but by actually compiling packages from source and then install them to the system. By making the list of software as small as possible we hope to create a system that is easy to maintain, that requires little space on the hard drive(s) but at the same time is fully functional. We will also try to include configuration scripts for some administrative tasks, like setting up the network, to make it easier to administrate. Update: As of December 2002, the Neat GNU/Linux distribution is no longer available.

14. P!tux Linux
P!tux Linux is an operating system of the Linux family, based on Slackware Linux distribution and on kernel 2.2.x. It can be installed both on an ext2 filesystem (on a dedicated partition) or on a DOS filesystem (as a loopback device). It can be installed from DOS, Linux, in umsdos mode or via FTP. Basic installation requires a 486 PC with 8 MB RAM and 105 MB minimum hard disk space. During the installation another 150 MB will be used.

15. PapugLinux
PapugLinux is a minimal GNU/Linux live CD based on the Gentoo Linux distribution for x86 computers. The goal of PapugLinux is to provide a minimal but functional free operating system which can be run on most computers, from old systems with as little as 64 MB of memory to the latest powerful configurations.

16. Puppy Linux
Yes, Puppy Linux is yet another Linux distribution. What's different here is that Puppy is extraordinarily small, yet quite full featured. Puppy boots into a 64MB ramdisk, and that's it, the whole caboodle runs in RAM. Unlike live CD distributions that have to keep pulling stuff off the CD, Puppy in its entirety loads into RAM. This means that all applications start in the blink of an eye and respond to user input instantly. Puppy Linux has the ability to boot off a flash card or any USB memory device, CDROM, Zip disk or LS/120/240 Superdisk, floppy disks, internal hard drive. It can even use a multisession formatted CD-R/DVD-R to save everything back to the CD/DVD with no hard drive required at all!

17. SaxenOS
SaxenOS is a lightweight Slackware and Zenwalk-based distribution with the Xfce desktop. It is designed for older, low-specification computers.

18. SliTaz GNU/Linux
SliTaz GNU/Linux is a mini distribution and live CD designed to run speedily on hardware with 128 MB of RAM. SliTaz uses BusyBox, a recent Linux kernel and GNU software. It boots with Syslinux and provides more than 200 Linux commands, the lighttpd web server, SQLite database, rescue tools, IRC client, SSH client and server powered by Dropbear, X window system, JWM (Joe's Window Manager), gFTP, Geany IDE, Mozilla Firefox, AlsaPlayer, GParted, a sound file editor and more. The SliTaz ISO image fits on a less than 30 MB media and takes just 80 MB of hard disk space.

19. TA-Linux
TA-Linux is a free Linux distribution that targets Linux power users. Its main goal is to have a small base installation that the end-users can expand to include the software they need. The secondary goal is to support as many different architectures as possible, at this time x86 is fully supported with Alpha, Sparc, PPC and PA-RISC around the corner. Extra software not included in the base is handled using a system resembling the *BSD ports system, called Collection, which handles installation, upgrading and dependencies. The primary way of installing new software is to download the source, compile and install it (totaly automatic). The user can also choose to install already built binary packages, also automaticaly using the Collection system.

20. Tiny Core Linux
Tiny Core Linux is a very small (10 MB) minimal Linux desktop. It is based on Linux 2.6 kernel, BusyBox, Tiny X, FLTK graphical user interface and JWM window manager, running entirely in memory. It is not a complete desktop, nor is all hardware completely supported; it represents only the core needed to boot into a very minimal X Window desktop, typically with wired Internet access. This minimal desktop can be extended by installing additional applications from online repositories.

21. TinyMe
TinyMe is a PCLinuxOS-based mini-distribution. It exists to ease installation of PCLinuxOS on older computers, to provide a minimal installation for developers, and to deliver a fast Linux installation for where only the bare essentials are needed.

22. U-lite
U-lite (formerly Ubuntulite) is a light-weight distribution, based on Ubuntu, designed to run comfortably on old and low-resource computers. It comes with a careful selection of applications, such LXDE (featuring the Openbox window manager), Kazehakase web browser, Sylpheed mail client, AbiWord word processor and Gnumeric spreadsheet. Unlike most light-weight distributions, U-lite strives to provide a complete user experience out of the box.

23. VectorLinux
Vector Linux is a small, fast, Intel based Linux operating system for PC style computers. The creators of Vector Linux had a single credo: keep it simple, keep it small and let the end user decide what their operating system is going to be. What has evolved from this concept is perhaps the best little Linux operating system available anywhere. For the casual computer user you have a lightening fast desktop with graphical programs to handle your daily activities from web surfing, sending and receiving email, chatting on ICQ or IRC to running an ftp server. The power user will be pleased because all the tools are there to compile their own programs, use the system as a server or perhaps the gateway for their home or office computer network. Administrators will be equally as pleased because the small size and memory requirements of the operating system can be deployed on older machines maybe long forgotten.

24. wattOS
wattOS is a fast desktop Linux distribution based on Ubuntu. Using the lightweight Openbox window manager as its default user interface, the distribution strives to be as energy-efficient as possible so that it can be used on low-specification and recycled computers.

usar punteros es mas rapido que usar variables comunes.

el problema de los punteros es como gestionamos su uso, porque luego deusarlos hay que liberarlos.

para trabajar con estructuras de datos dinamicas, como listas, pilas y colas, vas a utilizar punteros.

los punteros te van a permitir crear estructuras de datos muy avanzadas y complejas, como por ejemplo, los arboles, y los grafos.

para algoritmos de busqueda por ejemplo, se utilizan punteros.


en fin, son impresindibles.

mejor acostumbrate a trabajar con ellos

los mayores desarrolladores de software se han dado cuenta que , no sirve JAVA en pocas palabras, es muy lento, chupa mucha computadora, es ineficiente, y no siempre se puede llevar un programa de un OS a otro.

existe hoy una nueva filosofia de programacion, ya no es "compila una vez, ejecuta donde sea"

ahora es

"escribe una ves, compila donde sea"


un ejemplo de esto son RealBAsic, QTcreator, etc.

se esta tomando un giro en esa direccion

la programacion me gusta mucho, me gusta mas que nada lo poco comun, vision artificial (aunque es muy pobre mi conocimient), algoritmos, cosas poco comunes.

el tema es que en mi universidad, por desgracia estan aceptando cualkier cosa, el ultimo trabajo, era una aplicacion web para reservas de ticket de bus (colectivos), no me parece que tengo que hacer algo asi, me da como verguenza, no me molesta el que lo hace, pero si me molestaria a mi presentar algo asi

Pq me intercambio la primera letra de las palabras y no la palabra entera ?

2 programas, identicos, uno en C++ y otro en JAVA, no se comportan de la misma manera:

1) el programa en C++ corre muchisimo mas rapido que el escrito en JAVA

2) en C++ pesa mucho menos (no se carga la maquina virtual)

3) Cuando se ejecutan programas compilados como en C++ hay un mejor manejo de la memoria RAM, esto beneficia al rendimiento global de la computadora


si ejecutas, 10 progrmas hechos en C++ , y otros 10 programas identicos escritos en JAVA, y esos programas son de una complejidad razonable (como un software para videoclub por ejemplo), me gustaria que veas cuanta memoria RAM usas para un caso y para otro, creo quecuando ejecutes los 10 programas en JAVA, tu computadora, ..... se largue a llorar.


C++!!!!!! , si te gusta algo mas visual .... C++Builder, es un gran producto.

muchas gracias, uso C++Builder 6

los componentes para delphi se pueden usar el c++ builder ???? quiza es medio boludo pero bueno pregunto
