...imistic and pessimistic locking. I don''t like using optimistic locking, because handling the conflict in my case is a real pain. I tried using pessimistic locking, and I can''t get it to work. This is my controller code: class DoerController < ApplicationController def do Locker.transaction do r = Locker.find(1, :lock => true) sleep 10 r.save! end redirect_to :action => :index end end If I start the do action at the same time on ports 8000, 8001 and 8002 (corresponding to my 3 mongrel servers), they will all finish at the same time. I exp...

...er security holes ? "Think small" is an unlikely reason that I can present to a VP. (not if I want to keep my job) ======================= There has been serious exploration of SAMBA as replacement for Netware by the Systems Group here at UK. Right now, they are testing a "Student Locker" system using SAMBA. It isn't widely in use yet, but results have been promising (I guess). One concern has been the amount of RAM needed for each SAMBA connection. On the test machine, SMB connections are using ~3MB/connection. At that rate, we'd need about 3GB of RAM to accomodate ou...

This release introduces a couple of new options for existing extensions: * A new option PresentOptionAsyncMayTear for the Present extension, * A new flag XFixesClientDisconnectFlagForceTerminate to the XFixes XFixesClientDisconnectFlags intended to be used by screen lockers, where the server must exit if the screen locker does. The other changes include various fixes, clarifications and keysym definitions updates: Alan Coopersmith (8): presentproto: Minor typo fixes Remove _X_NONNULL macro gitlab CI: run meson instead of ninja for test &amp...

...I was able to authorize R to run system command as root using login and password. But, I forgot to turn this function on before installing Bioconductor, so I terminated the process of the installation. Then, I tried to authorize R to run system command as root, I failed to do that because I saw the locker was not open. I am sure my login and password are correct. How can I recover this function? Thanks a lot, Senhua

Hola amor! Finalmente llegué a D.C. Ya estoy en el albergue pero el cuarto solo va a ser liberado a la una o tal vez dos de la tarde. Pero no importa al menos ya estoy aqui, ya tomé desayuno que por cierto es horrible. Voy a poder tomar baño y usar un locker por un dolar. Entonces voy a tomar baño guardar mis cosas y salir ya que aqui no hago nada. Cómo fue tu domingo? Cómo está Esteban? El viaje fue bastante tranquilo pero cansativo. Creo que dormí un poco en el aeropuerto. Llegué a eso de las 8:30 en el albergue pq yá estaba cansada del aeropuerto...

...his allows the structure to remain the same size, but at the cost of halving the max number of CPUs (127 for a 8-bit ticket, and a hard max of 32767 overall). The extra bit (well, two, but one is unused) in indicates whether the lock has gone into "slowpath state", which means one of its lockers has entered its slowpath and has blocked in the hypervisor. This means the current lock-holder needs to make sure it gets kicked out of the hypervisor on unlock. The spinlock remains in slowpath state until the last unlock happens (ie there are no more queued lockers). This code survives for a...

Hi there, As very much a new convert top Opensolaris & similar environments - I''ve been trying to get my head around how ZFS relates to NFS when dealing with user/group permissions. In my case I have set up an Opensolaris system with a zfs pool with sharenfs on. Now, I would like several Linux client to be able to access this share depending on their username, as I''m

There''s a possible security problem using auto idle logout programs and vt lockers. Try the following: get the pid of your shell, (sleep 10s ; kill -HUP <pid-of-your-shell) & vlock -a after vlock -a, you can''t change the virtual console on a Linux terminal. But if you log in, start vlock -a, enter your password you can change vt... The same happens when an aut...
