serialize() takes too long when serializing to a raw vector
Hello, R version 2.4.1 (2006-12-18) i386-pc-mingw32 Calling serialize() with a NULL connection serializes it to a raw vector. However, when the object to be serialized is large, it takes a very long time: > system.time( serialize(matrix(0, 1000, 1000), NULL) ) [1] 38.25 40.73 81.54 NA NA > system.time( serialize(matrix(0, 2000, 2000), NULL) ) [1] 60...

disabling serial in pxelinux
Hello from Vienna, Austria! I'm happily using pxelinux since years. However, I encountered problems on several machines, because they don't boot up properly with PXE. The problem is, that there are recently some devices connected to the serial ports of those machines. pxeboot echoes and listens to the serial console and the output of the menu results in (silly) input back from the serial port. That is considered as user input and stops the timeout counter: the machine won't continue booting. :-( Since I can't remove the seri...

[PATCH OSSTEST 0/6] Support for serial logs from marilith boxes
The marilith boxes use a conserver (http://www.conserver.com/) setup for serial access. Our installation exports the logs via http allowing us to grab them with wget. Sending debug keys with is handled separately via xenuse. xenuse ultimately speaks to the conserver too but it abstracts away the IP and port to use so this is preferred. With these changes the correct Serial h...

This patch adds support for serial output functions. It may be useful for debugging purposes since you can separate ordinary outputs from debugging dumps. Just add "serial.h", and use either serial_print or serial_puts as you would use printf and puts respectivelly. For QEMU, you only need to specify the option -serial st...

I have attempted to add the Serial Connections to a Guest, using both Virtual Machine Manager and by editing the .XML file, and I can add up to 4 Serial devices (Including one for console access to the guest) without...

detecting width overflow in serialized column with mysql
So I''ve got an ActiveRecord model pointing to a MySQL db, with an auto-serialized column ("serialize :columnName"). Thing is, MySQL, depending on how it''s configured (like, by default), has a bad habit of just truncating your data if it''s too wide for the column, with no error raised. Yeah, I can probably reconfigure MySQL and/or my AR connection...

USB to USB with standard USB cable will work. If one uses serial to USB adapter on the machine side (to create serial port through USB on the machine), then one _has_to_use_ APC cable: as John Pierce just said, it is APC special cable which though has serial connectors on both sides of c...
