Creating a discard/noreply email address with postfix and postfixadmin

On my mail server, I am using postfix/dovecot, with users in mysql managed by postfixadmin. At one point I had something set up to create an email address where email would be accepted, but immediately discarded. This is sometimes called a “noreply” email address. This setup stopped working, most likely when I upgraded the system… Continue reading Creating a discard/noreply email address with postfix and postfixadmin

Migrating a SolrCloud install from one location to another

This procedure has not been tested. I think it SHOULD work. Basic system administration skills are assumed. One thing to note is whether your collections have multiple shards. If they do, then the collection on the target cluster will need to have exactly the same sharding configuration as the source. For the compositeId router, hash… Continue reading Migrating a SolrCloud install from one location to another

Autism/Asperger stuff

Autism and the related Asperger syndrome are much in the news and on people’s minds lately. Here I will discuss my thoughts. Disclaimer: I have reason to think that I am personally in the Asperger camp. I have children and step-children who are officially diagnosed as Asperger. There are two topics I’m going to talk… Continue reading Autism/Asperger stuff

Certificate Fun – StartCom

I had been using StartCom for certificates for quite some time, because they offered them for free and were always reliable.  This was the case for both work and home.  This blog runs on my home server. Thanks to some funny business by the company that purchased StartCom, they have been targeted for distrust by… Continue reading Certificate Fun – StartCom

Choosing a Truck

I would like to engage the collective wisdom of the Internet towards choosing a truck.  The primary use for the truck is towing a large fifth-wheel trailer, something probably a little bit less than 40 feet long.  We expect a maximum tow weight of about 20000 pounds, with a hitch weight between 3000 and 5000… Continue reading Choosing a Truck

Is DNA universal?

I had a question come to me this morning, and I’m not sure about the answer. Is DNA universal?  If life evolves on a completely different planet, would it have DNA molecules just like ours, or would it evolve a completely different protein structure for its “code of life” than what evolved here?

mmo character rename

A couple of years ago, I bought Guild Wars.  It’s an MMO, but they don’t charge a monthly fee. I’ve had an online identity of “elyograg” for about twenty years now.  Naturally I wanted to use this name when I created my first Guild Wars character.  Something I didn’t know until faced with it: GW… Continue reading mmo character rename

I am lusting after a bunch of tools for car repair.  Below is what I want at the moment.  If you would like to donate anything on this list, feel free! Originally I was looking at Craftsman for everything, but it turns out that their “guaranteed forever” tool warranty only apply to basic hand tools.… Continue reading tool wish list

the inevitable slow decay

Last week, I forget which day, I woke up to a little problem.  I’d wet the bed.  The volume of liquid wasn’t huge, but that hadn’t happened since I was a kid.  Our 9 year old son currently struggles with this problem, but he’s got a VERY good reason.  He was diagnosed as a type… Continue reading the inevitable slow decay

having my head examined

Today I went to the eye center and ordered new glasses.  Here is what my prescription was in September 2007: OD: -4.50 x -1.00 x 174 OS: -3.50 x -1.00 x 178 Now it is somewhat worse: OD: -5.50 x -0.75 x 176 OS: -4.25 x -1.00 x 166 I was worried that I would… Continue reading having my head examined

We had a large 3-night group camp planned for Thursday July 22nd at Payson Lakes. The day before, we learned that there was an aggressive bear on the loose and they had closed the campground until it was caught. Not wanting to lose our chance to go to Payson this summer, we looked into later… Continue reading insane vacation
