Y2K38 Bug

In the next three days, every Linux or Unix people will start the thirty years of countdown before the unix timestamps overflows. This bug is called Y2K38 and it affects all unix-like operating system which represent system time as the number of seconds since January 1, 1970. Here's some technical description about it from Wikipedia:
This representation also affects software written for most other operating systems because of the broad deployment of C. On most 32-bit systems, the time_t data type used to store this second count is a signed 32-bit integer. The latest time that can be represented in this format, following the POSIX standard, is 03:14:07 UTC on Tuesday, January 19, 2038. Times beyond this moment will "wrap around" and be represented internally as a negative number, and cause programs to fail, since they will see these times not as being in 2038 but rather in 1901. Erroneous calculations and decisions may therefore result.
If you have used 64 bit system, then you can relax a bit, since 64 bit system have used longer bits to hold the date. I hope before 2038, i already bought a new 64 bit system big grin

Here's some illustration from Wikipedia

Running Rsync Via Proxy

One way to get the latest Slackware updates is by running rsync to syncronize your local repository and the main repository that hold the Slackware packages. Eric Hameleers has provided a great script called rsync_current.sh and how i modified this tool has been discussed on my previous post. In general, it works, except for one problem, when your computer is connecting to the Internet through a proxy.

My workstation at my office is connected to the Internet through a proxy, so i can't use normal rsync to work normally. I browsed the web and i found this site which tells us about how we should modify our squid configuration to allow rsync connection from any computer from our local networks. I asked my sysadmin to try this script. He agreed and he updated the squid configuration on the proxy.

Next, i need to update my environment variable RSYNC_PROXY to the host of the proxy and also the port. Let's say you are running a proxy on 192.168.1.1 and port 8080, then you need to run …

NVidia Legacy Unix Driver Update

NVidia has released an updated legacy drivers to support X.Org 1.19 with ABI 23. It has been mentioned in the UNIX drivers, but you can directly find the drivers from the links below:
NVidia 304.134 (x86x86_64)NVidia 340.101 (x86, x86_64) I have tested the 304.134 driver and it's working great here. I can finally remove x from my /etc/slackpkg/blacklist file since it's a showstopper for me.
Aside from legacy driver, NVidia has also released their latest driver 375.26 (x86, x86_64), which brings support for newer cards and also many new features (including X.Org 1.19 with ABI 23 support).
