What why video games are much better designed programs that type Office?

Archived on: Curiosity, Development, Informatica - Packo at 9:40 pm on Wednesday, May 14, 2008

"What why video games are much better designed programs that type Office? The games are designed by people who love to play with them. Programs and Office are designed by people who want to do anything else during the weekend. "

D Programming Language

Archived on: Development, Informatica - Packo at 10:30 pm on Sunday, February 17, 2008

Some time ago I read about this language which I quite liked the approach. I will put an excerpt from the Wikipedia but I strongly recommend that you read you the full article:

D is a programming language developed for general use by Walter Bright whose first version appeared in 1995, the result of decades of research and experience of skilled programmers in many languages.
It is of a higher level than C + +, but retains the ability to write code for high performance and interconnect directly with the APIs of an operating system or hardware. In addition behaves well with large-scale programs with a million lines, which develop teams of programmers.
D is easy to learn, provides many functions to help the programmer, and plays well with the technology of aggressive compiler optimization. It is a compiled language, not interpreted. Is a language that is practical for programmers who need to get a job completed quickly, with a code easy to understand.
[...]
  • Automatic memory management (garbage collection)
  • Delegates, nested functions and roles verbatim
  • Operator overloading and properties without burdening the programmer
  • Structuring: modules and packages
  • Properties
  • Generic programming much improved
  • Programming contracts
  • Reliability and maintainability
  • Conditional compilation without dirty preprocessors
  • Compatibility with C without pay C
  • Associative arrays

Some time ago I read in Version Zero a table that had translated freely in another article on Coding Horror, and I liked it, the pointed to one day put on my blog and here it is:

SSH discover

I made a python script that, given a network tells you in what hosts are running an ssh server.

The operation is as follows:

  Usage: ssh_discover <subnet> [<PORT>] 
          It subnets support: *.*.*. 0 and *.*. 0.0 
          Example: ssh_discover 192.168.2.0 
                          ssh_discover 172.169.0.0

Python style guide in Spanish

Archived on: Development, Informatica, Recipes and tricks - Packo at 5:14 pm on Monday, August 27, 2007

Have brought this style guide for progrmación Python translated into Spanish.

Guide.

It's very interesting to follow the style guides to understand that all other code. It facilitates the reuse of code, debugging and improvement of it, go a choy.

Creation of visual applications for mobile Java easily: SVG

Archived on: Development, Informatica, Recipes and tricks - Packo at 7:32 pm on Friday, August 24, 2007

The other day I read that is not where Netbeans provided a way to develop graphical applications for J2ME, bone and mobile handheld devices, quite fast, scalable and highly spectacular results.

All this makes it through the new medium of SVG Tiny, and the tool-type "FlowDesign," Bone by design flows, which provides Netbeans.

What do we do to create an application? Very simple, NuevoProyecto-> Category: Mobile -> Proyects: Mobile Application -> Name of the project and little things well -> Emulator Platform: Sun Java Wireless Toolkit 2.5.1 for CCD, EA -> Device Configuration: CCD 1.1 -> Device Profile : MIDP 2.0 -> Finish.

Once this is done the initial outline with a form of initiation. Erase it from the palette and drag (on the right) is the component that we want to SVG, an image to begin with, once you get on the board, we copy an image SVG (Tiny) src to the project, will appear as resource, the drag the component that we have before. To end the flow, we add a component to "StopCommand" from the palette, as always: dragging. Now we see a signal flow connection with the label "Exit", then join with it that says "ExitPoint" in the MobileDevice and voilá! we already have a graphical application for mobile don 't you think so? Then you will press F6 and the emulator with the widget.

The most complicated of this is the topic of SVG, they have to be special and I do not have on hand any program that could make them, and postearé the second part of the Institute with applications that handle these kinds of images.

Requirements:
- Netbeans 5.5 with SDK> = 1.5
- Netbeans Mobility Pack 5.5
- Sun_java_wireless_toolkit-2_5_1-ea

I tested this with a Nokia N80 and it works (which I do not remember if it is tried with the sdk from Nokia, but I think I tried with both).
