comment Is there a video capture device for IRIX & Sparc video?
Got an adaptor, so the CRTs are out. Yay.

Good suggestions, but I'd prefer something I can bring my laptop to.

comment Is there a video capture device for IRIX & Sparc video?
That assumes that they are in working order. I want to be able to control the boot process too. Some machines have a serial console, but SGI for example is very graphical. I can keep their keyboard (if special), but the CRT is a bit big. Would prefer to not have to lug even a LCD screen in place, which is why I'd prefer a video capture USB device.

comment Bridge virtual machines out WLAN interface
@Gleb: Uh... no. But one blob of code is less that three blobs of code. The less code the host runs the better. And DHCP-client and NAT processing code has historically been much buggier than bridge-code.

comment How do I free up deleted data to the filesystem in MySQL
I tried "alter table history;". Is that what you meant? There was no effect.

comment Bridge virtual machines out WLAN interface
It's not straingforward because the firmware is actively blocking it. And I do get away with not having an IP on the host when I use my wired network. Bridging the guests works perfectly without NAT or the host OS having an IP address.

I'm the user, and no it wouldn't be. It's the ugly fix I'm going with though.

comment protecting my files from root
This will not help at all. If you have root on the host machine then you have complete control of the virtual machines. If nothing else root will be able to suspend the virtual machine to disk and just extract any crypto keys from the state file (the "RAM" from the virtual machine).

comment Bridge virtual machines out WLAN interface
No IP address on the host because of security reasons. Then the host isn't vulnerable to ping of death, NAT inspection (state "related" in iptables for example) bugs, and DHCP client bugs, all of which have happened. (I need DHCP client, not static IP for when the networks use DHCP snooping with ARP inspection). I want no IP processing on the host OS whatsoever.

comment Real one-time passwords (OTP) on Linux other than S/Key?
Me too. I log in to BSD, Linux and Solaris boxes with Yubikey. Cheap and awesome.

Find, sed and awk in one line. I love that (I do it too).

comment How to identify/use existing fiber installation?
I would say that nowadays multimode is just for suckers. Use singlemode for everything and you'll never have the wrong kind. Also just one type of spare parts (per link speed).

comment Fast imap server for larger folders
Thank you for the link and diagram. I have done some subjective "feel" benchmarking and it seems that dovecot is slightly faster once it has cached the index, but since emails keep trickling in the cache is soon invalidated so in practice I get the slow hit every time I open the mailbox. dbmail seems to take the hit incrementally on email insertion (makes sense), so it's while it may not be quite as fast, I never get the 10s wait to open a folder. Tested with 44'000 emails in a box.

It's a problem, yes. I want to have "screen" for X apps.

I've tried to optimize using the tuning page. This is as good as I got it. I'll try dbox.

And not 40'000 mail headers. They are loaded on demand if I scroll.

comment Fast imap server for larger folders
My point is that it's not much data. 40'000 entries is nothing to a database. It shouldn't be much for an imap server. It's a virtual machine (KVM on Linux) on a quad-core 2.4GHz with raid5 and 8GB RAM, but I've seen this on a physical machine as well. I've benchmarked the disks and network and I get about than 100MByte/sec. But remember that all this is just reading select mail headers (from, flags, subject) of about 40 (the latest) of 40'000 emails. Not even the 40 mail bodies.

comment Fast imap server for larger folders
Yes, I'm using the indexing. The thing that confuses me is that an SQL database would not take 10 seconds to list the newest 40 rows (when properly indexed). I've updated the question with this.

comment Do routers have IP Addresses?
Almost right. On multiaccess networks the IP is of course used to find what circuit (frame relay or ATM) or what destination MAC (ethernet) the router is on. Not needed for the router itself though. So maintenance is not the only reason.
