Comentario de Javier en Manuel Saco estrena blog

Manuel Saco es un escritor y periodista pésimo. El análisis de Belen Esteban de la actualidad es mil veces más culto, preparado y detallado que el de este pseudo-escritor.

Cree que todo vale por el dinero y hace lo que sea por dinero, sí, lo que sea.

Llamarle tonto sería halagarle.

Tu solo cree en los Escolares. Juas, vaya tonto.

Comentario de D en 10 razones para ilegalizar los matrimonios homosexuales

Fri, 16 Jul 2010 13:43:33 +0000

Personalmente, me encuentro en contra del matrimonio homosexual. Se que tengo ciertos motivos religiosos pero tambien, estudiando cuestiones de derecho civil, me parece que hay fundamentos para no aprobarlo porque habria que modificar partes sustanciales de la constitucion. No voy a pasar a detallar los fundamerntos porque es muy largo y dificil de explicar via texto.
Mi participacion se da principalmente con la intencion de responderle a Karo.
Soy heterosexual (creo que estaba claro) pero tengo amigos gay y amigas lesbianas a los cuales quiero mucho, sin embargo, sigo sin apoyar la ley por cuestiones personales, de la forma en como me educaron y admito que en parte religiosos.
Quisiera aclarar que las cuestiones patrimoniales (de plata) no son relevantes en mi parecer, apoyo completamente la union civil. Realmente no me importa si tienen bienes ganaciales o si en caso de fallecer uno hereda el otro o si comparten obra social, etc. Es mas, me parece muy bien que se les concedan estos derechos.
Sin embargo, mi principal objecion con el matrimonio no viene por este instituto en si, sino por la cuestion de la adopcion. Personalmente no considera que pueda ser un buen ambiente para que se crie un chico, mas alla de todo el amor que le pudiesen dar, no es natural que una persona se crie con dos figuras paternas o dos figuras maternas. independientemente de que la que le falta la pueda tomar de un pariente no padre o madre.
Eso es todo lo que queria decir, respeto completamente al que opina diferente que yo y pido respeto hacia mi opinion.
Saludos…

Comentario de personal loans en Con la Iglesia hemos topado

personal loans — Sat, 10 Jul 2010 10:02:06 +0000

Following my analysis, thousands of people on our planet get the loan at various banks. Thus, there is a good possibility to find a small business loan in any country.

Comentario de MauraMurray en La Libertad de Expresión o Santa Bárbara

Some time before, I did need to buy a good house for my organization but I did not have enough cash and could not order something. Thank God my sister suggested to get the credit loans from trustworthy bank. Thence, I did so and used to be satisfied with my auto loan.

What happened

• The Mars Pathfinder probe lands on Mars on July 4th
1997
• After a few days the probe experiences continuous
system resets as a result of a detected critical (timing)
errorerror

Software Architecture

• Cyclic Scheduler @ 8 Hz
• The 1553 is controlled by two tasks:
– Bus Scheduler: bc_sched computes the bus schedule for the
next cycle by planning transactions on the bus (highest priority)
– Bus distribution: bc_dist collects the data transmitted on the bus
and distributes them to the interested parties (third priority level)
– A task controoling entry and landing is second level, there are
other tasks and idle timeother tasks and idle time
• bc_sched must complete before the end of the cycle to setup the
transmission sequence for the upcoming cycle.
– In reality bc_sched and bc_dist must not overlap

The problem

• The select mechanism creates a mutual exclusion semaphore to
protect the “wait list” of file descriptors

• The ASI/MET task had called select, which had called pipeIoctl(),
which had called selNodeAdd(), which was in the process of giving the
mutex semaphore. The ASI/ MET task was preempted and semGive()
was not completed.

•• Several medium priority tasks ran until the bc_distSeveral medium priority tasks ran until the bc_dist task was activated. task was activated.
The bc_dist task attempted to send the newest ASI/MET data via the
IPC mechanism which called pipeWrite(). pipeWrite() blocked, taking
the mutex semaphore. More of the medium priority tasks ran, still not
allowing the ASI/MET task to run, until the bc_sched task was
awakened.

• At that point, the bc_sched task determined that the bc_dist task had
not completed its cycle (a hard deadline in the system) and declared
the error that initiated the reset.

• ASI/MET acquires control of the bus (shared resource)

• Preemption of bc_dist
• Lock attempted on the resource
• bc_sched is activated, bc_dist is in execution after the deadline
• bc_sched detects the timing error of bc_dist and resets the system

The Solution

• After debugging on the pathfinder replica at JPL,
engineers discover the cause of malfunctioning as a
priority inversion problem.

• Priority Inheritance was disabled on pipe semaphores
• The problem did not show up during testing, since the
schedule was never tested using the final version ofschedule was never tested using the final version of
the software (where medium priority tasks had higher
load)
• The on-board software was updated from earth and
semaphore parameters (global variables in the
selectLib()) were changed
• The system was tested for possible consequences on
system performance or other possible anomalies but
everything was OK
