Integrated KVM connector

Posted 05-02-2012 at 09:09 PM by Skaperen

We need a standardized integrated connector that supports ALL of the following in one connector:

1. Dual DVI data links for video up to 2560x1600
2. Single VGA compatible analog signal likes (as in DVI-A)
3. PS/2 keyboard connection
4. PS/2 mouse connection
5. USB

Then maybe the KVM switch market can get their act together.

BIOS still not smart enough

Posted 04-30-2012 at 01:45 PM by Skaperen

BIOS is still not smart enough, and has failed to reach the "holy grail" of doing just what system administrators want it to do. This means you AMI. And the others, too.

What I (and just about every system administrator I've talk to about this) want is to be able to specify a device boot order that does NOT get modified by the BIOS just because the media or device is absent in a future boot cycle. I want to have the USB memory stick be the FIRST boot device, conditional...

Why is netfilter in kernel space?

Posted 04-21-2012 at 03:11 PM by Skaperen

Isn't one of the kernel design intentions to move more things to user space and keep the kernel itself smaller? I think network filtering should be one of those things.

So why haven't they done that? Is it considered too much of a performance issue to use user processes filter packets? I don't think it would be. But maybe there is some functionality missing that can be done in the kernel and not in user space?

The API would not be hard. Just create device nodes...

Rethinking network configuration

Posted 04-15-2012 at 02:43 AM by Skaperen

Previously I wrote about configuring interfaces with static IPs based on matching them with what actual network (subnet) the interface is connected to. Now I'm thinking about it in even more different terms. But this concept will need some changes in the kernel itself.

To start with, the kernel already (by default) will "leak" an IP address to other interfaces. Specifically, if an ARP query comes in on one interface for an IP address only configured on another interface,...

Browsers still re-fetch pages when using back button

Posted 04-11-2012 at 11:42 AM by Skaperen

Browsers these days are still trying to re-fetch data when I press the infamous "back button". I think this was always a dumb idea.

No doubt that is the cause for many cases of web site double ordering. Someone backs up so they can print out the results of a previous page where they committed their order, and it causes the data to POST again, which places another order. Now days, for POST, you get a pop-up that says the browser needs to re-post the data.
