Nombres de dominios

¿Cómo es el proceso de registro?
¿Por qué hay tanta diferencia en los costos de los nombres de dominio?
¿Qué ocurre si olvido renovar mi nombre de dominio?
¿Puedo comprar y vender un nombre de dominio?
Estas y muchas otras preguntas son respondidas en la Guía para principiantes para nombres de dominio publicada por ICANN (Internet Corporation For Assigned Names and Numbers), el organismo que regula los nombres de dominio.

Fix Audio Windows on MAC

  [GUIDE]  DSDT override  eGPU error 12 fix (Windows only)   here   ◄  Mac owners  please work through this thread to solve error 12 before doing a  DSDT override here   ◄  pre-compiled  DSDT overrides   - load or use as reference when making your own   Introduction   A Windows system's DSDT table root bridge definition (ACPI PNP0A08 or PNP0A03) is usually confined to a reserved 32-bit space (under 4GB) budgetted to be large enough to host the notebook's PCIe devices. A watermark TOLUD value is then set and locked in the system firmware. Windows OS honors the root bridge definition and will allocate PCIe devices within it. macOS ignores the root bridge constraints as too does Linux when booted with the 'pci=noCRS' parameter. Neither of those OS require a  DSDT override  and can allocate freely in the huge 64-bit PCIe address space.   When retrofitting a eGPU, an   error 12 (This device cannot find enough free resources that it can use)  can occur  against an eGPU in Win

Using real data types in VHDL

Using real data types in VHDL    Apart from the standard types like integer and std_logic_vector's VHDL also offer  real  data types. But a real data type has a big disadvantage. It is not synthesis-able. It can be used only for simulation purposes. This disadvantage limits its use to a large extend, but there are plenty of projects where we look only for simulation results.   Before starting the coding part of a VHDL project,one has to decide whether the project to be implemented on a real FPGA or just a computer simulation is required. If it has to be ran on FPGA, then forget about the real package and use only synthesis-able data types like std_logic,integer etc... Otherwise you can reduce the time and complexity of your project by using real data types. The real data type is defined in the library called  MATH_REAL . So you have to include the following line before the entity declaration in the code: use ieee.math_real.all; The math_real package also offers some elemen
