Here is an orig­i­nal com­po­si­tion I wrote, called Grace, for flute, clar­inet (in Bb) and pi­ano, based some­what on the hymn “Amaz­ing Grace”. I’m pro­vid­ing it for free, un­der copy­right, but if you de­cide to per­form it, I would ap­pre­ci­ate it if you would let me know!

Here is the up­dat­ed ver­sion of my [pre­vi­ous au­then­ti­cat­ing/for­ward­ing Squid 3 con­fig](http://non­graph­i­cal.com/2008/09/squid-3-proxy-chain­ing/). It adds some things and fix­es some things. In par­tic­u­lar, the peer ex­clu­sion rules from the pre­vi­ous con­fig were not work­ing - this one should cor­rect­ly *not use* the par­ent prox­ies when query­ing “lo­cal ad­dress­es”. As be­fore, the con­fig­u­ra­tion file con­tains two proxy servers for load bal­anc­ing; it can be ex­tend­ed easi­ly to in­clude more. Read more…

I have been hav­ing, to put it light­ly, some prob­lems with VMware server and an Ubun­tu guest. My guess as to why is this: VMware server is, in my eyes, built for pro­duc­tion-level server vir­tu­al­iza­tion. It’s not re­al­ly built for on-the-side home server vir­tu­al­iza­tion, like the kind that I’m do­ing, and on fair­ly desk­top-ori­ent­ed hard­ware to boot. Ba­si­cal­ly, my Ubun­tu in­stall often has trou­ble with disk ac­cess, and some­times net­work ac­cess as well. (I’m run­ning a Vis­ta Home Premi­um host with an Ubun­tu Server 8.04 guest.)

[Down­load `crar­chive` ver­sion 0.1.][crdl]

Here’s a lit­tle pro­gram I wrote to solve a small prob­lem I’ve been hav­ing with cron. Say one has in one’s crontab the fol­low­ing line:

0 0 * * * /usr/bin/rsync -avz dir1/ /back­up/dir1/

This backs up `dir1` to a back­up di­rec­to­ry. `rsync`, how­ev­er, cre­ates a lot of out­put (espe­cial­ly with the `-v` switch)… and cron sends that out­put to your email, so ev­ery day, you’ll be get­ting an email mes­sage from cron with the re­sults of the back­up. To avoid this, most peo­ple sim­ply redi­rect the out­put to `/dev/null`. What if I do ac­tu­al­ly want to see the out­put though, just not in my in­box?
