UNDER REVISION
 
WILL REPOST when complete. This way if you're viewing this document, you don't have to spoil a single read by witnessing the revision cycle. This is my method to view the journal live with certain parameters in place, a work-around during editing where the standard preview function isn't adequate to my purpose. -nis

ON MY BIRTH CERTIFICATE, it says my father was a technical writer; if I had to pick a description for what I do today, that wouldn't be entirely off-base. The phrase described him no better than it describes me, yet either could lay claim to that title.
 
His skill was applied to authoring manuals for periscopes, for the U.S. Navy, I think is how the story goes. Later, he started his career in the advertising business, as a copywriter, and was quite good at it. When the Internet came along he was published in trade magazines dealing with technical subjects.
 
My uncle (his brother) was a newspaper editor for most of his working life.
 
 
I'VE BEEN looking at Mini-ITX computer mainboards lately; I had the idea I might want another computer system to replace aging hardware, and after looking over the Mac Mini from Apple, I did what I usually do when I get a hankering for new computer hardware… I visited  LinuxDevices.Com to see what's doing with Linux on the smaller hardware platforms (anything smaller than desktop computers and laptops). For years, I've looked there <lj-cut text="Read more"> for a certain envisioned substitute for either a laptop, PDA or tablet style of computer, that would run Linux and convey the benefits I was after in a device the size I thought most useful.
 
I'm not as plugged-in as people suspect of me; I hadn't noticed that the Mini-ITX form-factor had taken off in a significant market. They seem to be doing a fair amount of sales these days, judging by the participation seen in technical forums covering this style of computer motherboard… and concomitant smallish enclosures and appropriately-sized LCD displays to go with them… as well as forums covering related subjects such as power-efficient and near-silent computer platforms.
 
People are beginning to identify to a finer grain, those parts of the user experience that are important to them, as they spend more time using these machines.
 
 
I began pricing Mini-ITX systems, with an eye toward doing better (price-wise) than I could do at the Apple (online) Store -- for pretty much the same kind of machine: one that is unquestionably smaller than its larger work-alikes, lighter in weight, and, I hope… draws much less electrical power to keep it going, day and night.

It is no longer necessary to tell people why I'd want to do that [run a computer all day and all night, unattended]; back in the day, the BBS I ran (called 'Johannes Kepler BBS') … ! … had to be available 24 hours a day, 7 days a week, except when feigning BUSY (telephone in use to another person, voice to voice as it were) or truly BUSY with BBS traffic (something of a rarity). If it weren't, I'd lose the interest in the BBS from the few callers who bothered to call it and investigate it. So it had to be ready for a phone call from another computer's modem, without advanced notice (just as today, your ISP had better be ready to accept your modem call, if you're still on dial-up, 24/7).
 
It's no longer necessary to describe all this to people because anyone who uses a computer much notices how annoying it is to have to start over with a generic desktop and session into the computer's operating system (what you get when you boot the machine from a cold start, and login… if required).
 
It still costs money… to operate; the wear on the machine's electromechanical parts; the thermal stress on the electronic components; and the utility bill from the local electric light company at the end of the month… it adds up. It adds up more when you want to operate more than one machine, part or full-time.
 
If the software were perfected, and you could rely on all the power-saving features of modern systems… if the ad copy was as true as the result you got when you bought the appliance and took it home and beta-tested it… that'd be one kettle of fish; but this is another: it is not that way, and when it is, you pay in some other way, such as vulnerabilities to both household and Internet-wide security matters (ranging from an unauthorized installation of defective entertainment software that slows the system to a crawl, to malware acquired over the Internet pipe).

At some point the Buy It Now syndrome began to take hold, only this time I was questioning it, because I'd tried to buy this kind of happiness one too many times, and found the result through trial and error to be big on error and also it was trying.  I looked a little deeper into the specifics of the systems I was interested in trying —specificially at the VIA EPIA series Mini-ITX mainboards, and systems based on them.

The VIA-based boards are a popular choice for stand alone firewall systems (which I'm sure you're aware of since it sounds like you are probably more current on the hardware than I am, at this point).

Indeed … a primary application for me. They even offer 1 GB solid state IDE 'drives' to make it entirely non-electromechanical (making it strictly electronic and not at all mechanical) which should help with the 'bolt it to the underside of a table, shelf or cabinet, run 12 volts and an Ethernet cable to it, and a line to the telco c/o and forget it' approach, which would be ideal here.
 
The big questions are about the general reliability of the fanless technique and approach (it sure looks like I'll be playing it safe and running a fanned case after all, but still jones-ing for the fanless cases with the fins and the dead-quiet operation characteristic); as well as ultimate support of the platform on preferred operating systems (Linux, *BSD) so that I can retask it as my needs change.
 
I'd like to have two or three such systems, to divide the labor (and security aspects) into distinct functions; a stand-alone firewall should ideally not also double as the client engine (even running remote X11 terminal to a box ferreted away in a closet, there is the temptation to double-up on functionality and use the closet box as the RAM and mass storage for the client, where the client machine itself only does the rendering.
 
Plus now there is this problem with capacitors to worry about (that's part of the unwritten end of the above post, which is nowhere near complete; I spent a lot of time trying to get the structure worked out as a template for future technical articles I may author -- my recent foray into Wikipedia has changed a lot my approach to HTML authorship, and its spreading virally to all my work!)
 
*** RUMOUR REPEATED BELOW
The deal with the capacitors (as you may be aware) is that a large quantity of bad ones made it into the production lines of many different motherboard manufacturers (including VIA) according to the rumour mill. Apparently, some industrial espionage led to an incomplete picture of what was supposed to be a complete formula for a good capacitor, and someone went into production with the bad formula (some new water-based electrolyte formulation, I think). Manufacturers did not do enough regression testing of the new parts, and they all went bad about 4-6 months into service (esp. at higher ambient temps inside the case). This affected major brand-names of motherboards, names we all know and 'trust'. In some cases the manufacturers went belly-up attempting to rectify the issue, which was reported as widespread.
 
AS I ONLY GET TO do this one time (if that; undecided here) I would kinda like to get it right the first time. There are plenty of other kinds of related devices I'd also like to get my hands on, and the fact is, I already have two systems that do function 'good enough' in the same capacity as the new VIA EPIA based system would (albeit not with a gig of RAM, which is what I'm shooting for). I'm also chronically low on disk space.
 
I may do nothing and sit on my hands all winter (and concentrate instead on 'wanting what I have, instead of having what I want'. It is very interesting to me to observe myself in this process; it is a lot like going shopping at brick and mortar places with absolutely no cash or credit in my wallet -- like (Hercules? Sinbad) chaining himself to the mast, knowing the Sirens are nearby. Ulysses.
