I’ve got a pretty nice free setup for a webserver I’ve been taking for granted now. So for anyone starting off wanting to setup a server with email, webserver, and database here are some applications I’ve found reliable and somewhat easy to figure out.

Pi bits
A couple of really handy things that may not be obvious when using the RaspberryPi.
Rackspace and FreeBSD
(2016 note – Debian ended up winning!)
This took me a bit to figure out and almost had me switch away from FreeBSD to Debian! Oh my! Exciting I’m sure. Briefly this site was completely down due to this.
RaspberryPi wifi restart
(2016 update) I actually wondered where this one went!
I’ve got a Raspberry Pi that keeps losing its wifi connection whenever the microwave runs too long. Here’s at least one way to get around this since the wifi doesn’t seem to rescan on its own.
Arduino Project #1
Recently I discovered the Arduino. Its an open source microcontroller that makes playing with electronics more fun for the computer programming savvy. Rather than having to find all sorts of components and understand a bit too much of how they all work, you can have the little microcontroller do it for you. Great! I’ve a couple of “experiment with electronics” sets to compare against and the same projects are 1000000% easier using this whole new fangled ‘computer’ thing. I’ve got many projects planned now.
The first is just scary eyes it being Haloween. Nothing fancy but they are actually a bit creepy from the outside.
Here’s the Arduino and breadboard – pretty easy:
Copying forward posts from an old Drupal install in case they help and also to pad this blog a bit! Also copying the comment on this one since it’s probably better than my post:
(2016 update – And who knew Hamilton helped him write it! :))
If ‘pro’ is the opposite of ‘con’, what’s the opposite of progress? Congress!
In George Washington’s farewall address he warned about the problems of political parties. Just a few relevant quotes from 1796.
A bit on how the few can control the government – this applies to both parties equally:
All obstructions to the execution of the laws, all combinations and associations, under whatever plausible character, with the real design to direct, control, counteract, or awe the regular deliberation and action of the constituted authorities, are destructive of this fundamental principle, and of fatal tendency. They serve to organize faction, to give it an artificial and extraordinary force; to put, in the place of the delegated will of the nation the will of a party, often a small but artful and enterprising minority of the community; and, according to the alternate triumphs of different parties, to make the public administration the mirror of the ill-concerted and incongruous projects of faction, rather than the organ of consistent and wholesome plans digested by common counsels and modified by mutual interests.
A bit more on the rule of the few via their two parties, sounds pretty darn familiar to our current situation:
The alternate domination of one faction over another, sharpened by the spirit of revenge, natural to party dissension, which in different ages and countries has perpetrated the most horrid enormities, is itself a frightful despotism. But this leads at length to a more formal and permanent despotism. The disorders and miseries which result gradually incline the minds of men to seek security and repose in the absolute power of an individual; and sooner or later the chief of some prevailing faction, more able or more fortunate than his competitors, turns this disposition to the purposes of his own elevation, on the ruins of public liberty.
Also nothing is new in the ‘divisions’ we often fall into just in association to where we live:
In contemplating the causes which may disturb our Union, it occurs as matter of serious concern that any ground should have been furnished for characterizing parties by geographical discriminations, Northern and Southern, Atlantic and Western; whence designing men may endeavor to excite a belief that there is a real difference of local interests and views.
The wikipedia article explains his view here a bit more succintly but I thought it nice to actually look to what he said also. We’ve too much trust anymore of the first source of whatever fact we want to hear on the internet or in general.
TF300 becomes dogged slow with time
Apparently so does the 2012 Nexus 7.
Over time I’ve noticed that the TF300T tablet I have has become almost unusable. It just hangs and hangs. Looking into this it appears that with these newfangled devices you need to worry about how well the storage performs. I totally get that having gotten the Rasberry Pi. I bought the cheapest SD card so any disk access is dogged slow.
So it turns out that Android just freezes due to slow disk access on Asus tablets. Here are some benchmarks discussing that. Next time I buy a tablet or phone I’ll make sure and check how well the storage performs. Its been ages since that mattered but it does once again.
I was clued into this with this Ars article about Android 4.3 and its addition of TRIM support. iOS doesn’t need TRIM support (as far as I’ve found) as apparently the storage doesn’t suck. 3-5 years in and both the iPod touches (2nd and 4th gen) have no horid freezes like the 9 month old Android tablet.
So you do in a way get what you pay for and again Apple products may be again worth the premium (I say as I write on the perfectly functional 5 year old MacBook, about to watch movies on the 7 year old iMac both working perfectly fine still). I suppose considering how old the Apple products are I don’t know much about the newer ones…
Tora Tora Tora!
The Tora Tora Tora group at Oshkosh 2013 was pretty impressive. Here’s a bit of it, it’s always so hard to believe these days being attacked from air. You really have to feel for the normal folk who really went through things like this, I can’t imagine living through the Battle of Britain, the bombing of Germany, you name it.
We were on a rowboat on Lake Wingra when that B-17 flew over on its way to the airshow. Glad it didn’t bomb us!
Raspberry Pi!
I gave into impulse and bought a Raspberry Pi finally. Not sure what I’ll do with it but it cost around $60 (with case and SD card) so why not give it a try?
I have it running Drupal right now. Works fine but a bit slow. I think the slowness is the SD 4 Class SD card serving as the database filesystem though… Use an external USB disk and I bet it’d be decent. Once the pages are in memory its plenty fast.
It’s so tiny:
Who needs a big computer? Me still. Here the Pi is on top of a small box of a computer:
