Radiation


After reading fear porn claiming the west coast was being fried by radiation from Fukushima, I bought a Geiger counter so I could measure for myself.

Background radiation on any given day is measuring between .09-.11 microsieverts. This works out to 876 microsieverts a year which is about a hundred fold under the lowest dose associated with an increased risk of cancer.

Not really sure how this compares to normal background radiation. This is just outside of Seattle. But it certainly falls far short of being "fried".

I once calculated that a cubic meter of seawater would have about 4000 Becquerels worth of potassium in it. not sure if that's right, or how to convert that figure to Sieverts or Grays or Curies.
that was inspired by a report that scientists had found 11 Bq/m³ of Cs-137 in a sample from Hawaii. it was likely from Fukushima, since Pacific weapons testing ceased sixty years ago..
I am pretty sure they needed some specialized equipment and several days of monitoring to find that signature -- 11 Bq against a background of ~4000 Bq.

@BR 549 ☎ The unit I have has an actual Geiger Muller tube and a thin plastic case with a slotted back so anything can pass through to the tube. It is supposed to detect Alpha, Beta, Gamma, and X-rays though it claims to be most efficient at detecting Beta and Alpha. So it would seem not only can it detect them but it is most efficient at it. But it's kind of moot as Hanford is on the opposite side of the state and far to the south and so kind of kitti-corner and there is a mountain range that separates us. Portland is more fucked as they drink water from the Columbia that Hanford leaks into.

How I Came to run a Friendica Node...


I am 62 years old now, but my arrival at running a friendica node really started before friendica or even the Internet or home computers were a thing.

When I was three years old, I had a bad bout of pneumonia and was hospitalized for a couple of weeks.

During that time I was in a crib, my parents, adoptive parents actually, came and visited me but most of the time I was alone and so my parents bought me one of the early transistor radios to entertain me. I turned it up too loud and disturbed other patients so they bought me an earphone.

I listed to KJR mostly, it was a local Seattle radio station that used to have what they referred to as a top-40 format which means mostly they played the 40 most popular songs over and over again though they'd toss in an occasional oldie. Then virtually all radio was live, records were spun by disc jockeys not computers like today.

Then when I was five or six I visited some cousins in Spokane, there were three brothers and a sister in that family, two of those three have since died in motorocycle accidents involving alcohol, they were all heavy drinkers.

Anyway one of my cousins had a small radio transmitter that could transmit to a nearby AM radio. I was fascinated.

Around 4th grade I was able to read well enough to start to learn about electronics. At the beginning of the year I was reading below my grade level, by the end of the year I was reading at a 12th grade level. They wanted to understand my outstanding progress and I could only explain that I had this interest in electronics that none of my family shared, so I was forced to look up words I didn't understand in a dictionary often requiring recursive lookups to understand the words the dictionary used to explain the initial word I didn't understand.

When I was ten my father got divorced and moved away but a friend of my mothers bought me some old tube radios at Goodwill, they used to sell them for $1 a piece, to play with and I converted one into a small AM transmitter that had enough power to broadcast to radios within about a block radius. That was my first pirate transmitter.

In Jr high school, which were I was ran 7th to 9th grade, I got my hands on a used DX-40 transmitter. This was a Heathkit HAM radio kit transmitter that used a 6146 as the final output tube, maybe 60 watts if you really strained it.

It was originally VFO and grid modulated, I got a 1200 Khz crystal and modified the Pi section output for the lower frequency and converted the oscillator to a crystal controlled oscillator and used an amplifier to drive a plate transformer backwards to make it high level plate modulation. This transmitter covered about two mile radius with a strong signal and about seven miles with a receivable signal if you had a good receiver, I used a Sony Earth Orbiter.

I met some friends in Jr High who also ran a pirate station and went on to build some other transmitters from scratch. The one I ended up running for many years had two 811's for audio modulator tubes and 4 807B's for RF output. I ran it at about 100 watts output most of the time.

By this time I also obtained a Langevine Compressor / Limiter and modified it for asymmetric limiting so it only limited negative peaks. I had enough audio power in the modulator that there really wasn't a practical limit to positive modulation. This allowed us a much louder sound than the commercial stations in the area while still maintaining good audio quality.

With this transmitter I was able to reach clear down to South Seattle / Tukwilla from the North end of Seattle and we got record support from all the major labels that used to warehouse in Seattle back then.

I bought a used KARR transmitter from Western Surplus that originally was in use for Alaska Marine operator service. The thing had quarter-inch thick steel panels was about six feet high, 30 inches wide and about 24 inches deep and weighed around 600 lbs, the power transformer alone weighed 320 lbs. It was designed for high level plate modulation from the factory. It had two 4-440A's in the modulator and three in the final, really not enough modulator power for that much RF but I could never run the RF at full power owing to not being able to get enough electricity to power it fully. It had a transformer designed for three phase 208v but I used two of the three cores out of phase for 240 single phase operation. I had to get a larger filter capacitor since there was more ripple this way. Originally it just had to 4 MFD caps, I got a 100MFD at 4KV cap and paralleled, that fixed the hum.

I only ran this transmitter a few times but when we did we had a solid signal from Everett to half way to Tacoma.

I got my First Class Radio telephone license in my Jr. Year of high school primarily through self-study.

After I graduated high school I was still running a boot leg but two of my friends got busted and I was worried about losing my license if I did so I decided to put it away and pursue legal things. I worked at several radio stations as engineer, one as assistant, another as chief, and other as program director. I really enjoyed that work but I couldn't make a steady living at it, AM stations were sold every other year it seemed, at least the small ones where someone with my experience could land a job, and when they did it usually involved a format and staff change.

So I ended up getting a job fixing consumer stereo gear at Stereo Northwest, and that paid pretty decent but they want out of business.

So then worked for the telco for 17 years, but during that time after shutting down the pirate station, my friends and I since we couldn't safely broadcast any more being adults and thus possibly subject to real legal penalties and for me the possibility of losing my license which was a job ticket, we decided instead to write about pirate radio, other stations, technical articles, etc.

And at first this was done on manual typewriters, literally cutting and pasting articles, and photocopying to create a news letter.

But it occurred to me a computer would be a more efficient way to do it and this was 1981, by then four years out of high school. Home computers were just becoming a thing, so I bought a Trs-80 model III with scripshit and a crappy dot matrix printer.

My friends wanted to access it remotely so I purchased a modem however there was no support for the RS-232 port built in to the operating system. I wrote a simple driver for it in Z-80 assembly, initially I attempted it in BASIC but it was too slow to even keep up with 300 baud, the tremendous processing power of a 2Mhz 8-bit chip just was not up to it.

This enabled them to call and connect and write articles remotely but even back then there were people war-dialing, just like in the movie War Games, and they found my machine and started screwing with the files. So I wrote a crude BBS as a front-end with a password protected back door to get into the Scriptsit word processor. I also added an e-mail system and a file upload download system.

I was also working at the telco at this time and one of my co-workers had a surplus electronics business on the side. He had some floppy drives which were defective (he thought) so he sold them to me for $20 each, back then floppy drives were going for around $300. I hooked them up to my machine and discovered they had two heads (double sided), played with a program called Tracksess and found they would step 83 times before hitting the end of the rail, these were 80tk double sided drives which would store around 720k each, previously I only had two single sided 40tk drives that were about 180k each of which 40k on one was operating system. TRS-DOS didn't support these but an alternative operating system called NewDos did.

I bought two more of these drives from him and these two WERE broken but I had an oscilloscope and other gear necessary to troubleshoot them and found one had a bad head select diode and the other a bad pre-amp chip so for less than $5 in parts for each I had two more working 720k drives.

So I had a total of almost 3MB of disk space, a HUGE amount back then and on this space I installed Infocom games. A friend of mine created a hacked infocom driver that would take a user ID I stored in memory and use it for part of the saved file name so each user could have their own saved game states.

Then another person on the BBS scene, Glenn Gorman, who had written a room style message system, approached me because he wanted to sell his BBS commercially but could not because instead of using the standard RS-232 port he used a MicroPeripherals bus decoding modem that was ported non-standard. It's driver would not work with a standard RS-232 and he couldn't sell it anyway because of license restrictions.

By this time my driver had evolved into an entire language that was structured like Microsoft BASIC but was a superset of MS-BASIC. It had all the same commands that MS-BASIC had and more specific to BBS operation like a command that would take a text file and format it to the users screen width. It also had things like carrier detection and loss detection so when carrier went away it would restart the program interpretation at a specific spot and then go wait for carrier again.

The original deal was I'd port his BBS to my driver, we would sell the package and split the proceeds, but instead of working that way the way it worked out was he'd sell and keep all the proceeds and I did the same. That was okay as I was never really interested in selling the software anyway just wanted to run the BBS which became the main purpose, the news letter died from lack of interest.

So during the time I was doing the porting we both ran the same software, which he called Minibin, and people didn't understand why they would log in to one Minibin then call the other and their login didn't work, so to differentiate between the two he re-named his Minibin South and mine became Minibin North, but people still confused them so he changed the name of his to Jamaica South and I thought what the hells' up north? Eskimo North. So that's how Eskimo North was born.

And in that time I took his room message system, added my e-mail, upload/download, and games facility. It became immensely popular to the point where I was taking 300 calls a day on a single phone line which was constantly busy 24x7 and if you unplugged the line at 4AM and plugged it back in it would immediately take a call.

I decided to go multi-line, initially I tried OS/9 as another person, John Mudge, was running a 4-line system on a CoCo successfully but after messing with it a bit, I decided that 64K was just too memory constrained for what I wanted to do and instead in 1985 I bought a Tandy 16B with Microsoft Xenix, an early Unix clone.

Microsoft Xenix was buggy as all get out, serial ports wedged requiring frequent reboots, hackers hacked it, it was just a miserable pile of crap. Later SCO did a much superior port of Xenix which I purchased. That was most worthwhile.

I ended up upgrading the machine way past a Tandy 6000, I modified the CPU board to add an extra set of limit and offset registers so it could address more than the 1MB the 16B was designed to address. I modified the 256K memory cards to hold 1MB by running an extra address line with blue wire and replacing the 4116's with 4164's. The pinout of the 4116 and 4164's were identical EXCEPT the 4116's required +12v that became an address line on the 4164's making this an easy modification.

This allowed me to stuff 4MB in the machine along with three serial cards that each had three ports, along with the built in two ports supported a total of 11 lines.

By 1991 I was charging for access to cover the cost of the lines and 11 lines were maxed out so I bought a used Sun 3/180. This allowed me to have three 16-port Mux's and it had two super-Eagle 575MB hard drives, enormous compared to the two 70mb drives that were the max the Tandy would support. The 16Mhz 68020 flew compared to the 8Mhz 68000 and initially I had 16MB of RAM which I was able to upgrade to 48MB.

But Usenet News processing got to be so heavy the 16Mhz 68020 wasn't enough so I upgraded to a 25Mhz 68020, then a 40Mhz Sparc CPU (all in same full height VME bus rack). Then I got a retired Sun 4/330 from the telco where I worked, to offload the news processing to it and networked them together with the old coaxial ethernet. Later I bought two 4-670MP's with Ross Hypersparc RTK-625 CPUs (20k each for the CPU modules) and networked this mess together.

In 1992 the Stockton CIX was formed and since I already had a network and was getting some access through another local provider now defunct, I ordered three Sprint T1's and we were officially on the Internet.

Later I replaced the 4/670MP's with SS-10's, retired the 4/330 after it did a halt and catch fire number, and added a number of Ultra-2's. I then made the switch from SunOS to Linux on all but one SS-10, and then over time migrated to Intel hardware which I am still using today.

I later moved my equipment out of my home to a co-location facility because three t1's was not enough bandwidth and it was less expensive to co-locate my equipment than bring more bandwidth to my home. I also had the benefit of UPS and a controlled environment so it was all around a good move. Initially I co-located with ELI, a very good company but they were bought out by Citizens, a less good but still workable company except they were bought out by Integra a non-workable for my purposes company. In 2012 I moved all my equipment to Isomedia and like ELI they are very professionally run and provide good service.

So that is where I'm at today, primarily now providing Internet hosting, web hosting, email, virtual private servers. But I've always had an interest in communications whether it be radio or BBS but I've never really found any good Linux BBS software so kind of got out of it for a while.

I had an account on Facebook but presently I'm on my fourth Facebook jail because they don't like conservatives there so I decided fuck it, I needed to do something in the name of free speech. I've tried a number of social media platforms like ELGG but they never got an audience. I tried Mammoth and didn't like the short message length, basically like Twitter because you can't have decent in depth conversations in such an environment, or post long articles like this one.

Then I stumbled across friendica, and in spite of the fact that Hypolite Petovan and I are on opposite ends of the political spectrum he still allows me to say what I want to say and has been very helpful at getting this operational. While we have our political differences we both value freedom of speech.

For those of you in the fediverse who haven't tried a friendica node, I would like to invite you to try mine at friendica.eskimo.com/. And if you'd like to play with Linux online we still over Linux shell access as well as full graphical remote desktop access via x2go, vnc and on the web. We offer about a dozen different Linux distros for you to use and have Usenet and E-mail available on all of those platforms as well as three different forms of web mail, pop-3, and imap.

We offer MUCH faster Wordpress sites than any other commercial provider I've tested. We also offer virtual private servers. You can try our shell service free, eskimo.com/services/free-trial… Please feel free to explore our site eskimo.com/. I'm always interested in helping and/or sharing war stories with other Linux enthusiasts. At this point I am using Ubuntu for my infrastructure, moved from Centos in 2012.

Other than computers and Linux my main hobbies and interests are photography, music, cats, and you can view my photos and blogs on my home page at eskimo.com/~nanook. Thank you for reading!

@tofeo I find the functionality of friendica and hubzilla both to be good but the user interface, especially where groups are concerned, piss poor, so I'm looking into other platforms, not that I will discontinue these but to add, and I'm also working on my own theme for friendica hoping to resolve some of what I perceive as less than intuitive user interface through theming. But two things about friendica I do not think I can resolve this way is the difficult way it deals with groups and the lack of posting if you're in the global community view. One should not have to switch between views to make a post.

Life


I was adopted at three days old, I have no memories of my birth parents, but I remember the first day I was brought home. I know it's unusual to have memories before age two or three but I do have many, but of those the most vivid was one I had on my first day at my adoptive parents. My mother had me down in what was the laundry room and she had a pet spider money in a cage. She got rid of it a few days later at her doctors advise.

I am 62 now and I still remember that money and it is the memory of that monkey that proved that I did remember that day because she never told me about it, I related it to her many years later.

My mother had gone into menopause early (at 30) and did not believe she could have children of her own which was why I was adopted, but then 2 years and nine months later she became pregnant with my sister or step sister whatever that relationship is.

After my sister was born my father seemed to somewhat lose interest in me,
I never felt like I was "his", but my mother always treated us as equals. My
sister was very manipulative and always set me up, my mother saw through this,
my father didn't.

My father left when I was ten years old, and my mother worked hard and sacrificed much to support my sister and I, and really she had a life of sacrifice having been the eldest of five sisters and brothers and her own father having committed suicide at a fairly young age.

I don't think I ever adequately expressed the admiration and respect I had
for her and her life of self sacrifice.

Now both my adoptive parents have passed on. I was never able to find out
who my birth parents were and I somewhat regret that as I understand I have
three birth brothers who I would have liked to have known.

I had four children of my own, still married after 40 years, but I somewhat
smothered my children and two of them left home as soon as they were of age and
I have not heard from either in more than a decade. Instead of wanting love
they seemed both fiercely independent. My other two, first born is an adult
living with a woman but not married to her and I know they will not have kids
because of her poor health.

My second youngest is still living at home at 30, he is unusual as he has
memories of various previous lives. One of my other children also had memories
of her previous life but they faded when she was around six years old.

My wife works at night, I don't like this as it means I am alone most
nights, I work out of my home, running an Internet company which I've done most
of my life.

At times the universe seems overwhelming. The Beatles song, "All Too
Much" expresses my state well.

in reply to Nanook

An interesting life; I sometimes wonder if there are any families that don't have these strained relationships, we are a flawed society. I always look for the exceptions who rose above it all and created a decent life, treating other people well, with kindness, regardless of the tough journey through thoughtless and cruel people. They are the true heroes. It helps to focus on the good.

Vegetarians


Earlier I saw a post which had a picture of a dog and a pig and asked, "Why would you eat one and not the other", to which I replied, pigs taste good but dogs are too gamey. Really any lean meat not so flavorful. Obviously it was trying to make those of us who are carnivorous or at least omnivorous to feel guilty for eating pigs.

But then I got to thinking more, what allowed humans to evolve such large brains? And the answer to that is the combination of being omnivorous / carnivorous because meat is much easier to digest and extract energy from the plants, that is why cats have a very short digestive tract and cows need three stomachs and a very large digestive tract. And then cooking, cooking meat allowed us to digest it and extract energy from it even easier. And our brains consume more than 1/3rd of the calories we eat. Brains are very energy hungry organs.

And if we ate only vegetables, our brains would be starving for energy and not function well. And for proof of that all you need to do is spend about 30 seconds talking to any vegetarian.

Eskimo North's History


When I was around five or six years old, I visited a cousin and he had a low powered AM radio transmitter that would allow him to broadcast to radios nearby. I was fascinated.

A few years later, around 4th grade, I took a real interest in electronics and proceeded to read everything I could get my hands on related.

In 5th grade, I took a 5-tube all American table radio and converted it into a transmitter. It was crude but generated a few hundred milliwatts and could be heard for half a block or so away.

Through Jr. high and high school I ran a bootleg radio station, for most of that time around 100 watts and much of it 24 hours / day filling the wee morning hours with pre-taped programming. Occasionally, I ran a much larger transmitter that put out about 1000 watts but not for more than a few hours at a time.

I felt then and still feel today the monopoly the broadcast industry had on the airwaves was unfair and a blatant violation of the 1st amendment.

In 1981, now four years out of high school, several of my friends got busted by the FCC, and by this time I had my first class radio telephone license and was doing some work in commercial broadcast as well as working for Pacific Northwest Bell / US West, the regional telco, and decided it was not wise to continue so myself and friends decided perhaps since it was no longer safe for us to participate in pirate broadcasting that instead we would write about it and enable others in this pursuit of freedom.

At first we typed up articles on a manual type writer, literally cut and pasted them and then photo-copied them at a 7-11.

It occurred to me that a computer, word processor, and printer would be a more productive way to put a news letter together, so I bought a trash-80 model III with 48kbytes of RAM, two 180k floppies, and an Rs-232 port and a shitty dot matrix printer.

My friends wanted remote access so I obtained a modem and as there were no built in device drivers for the Rs-232 port, I wrote a primitive host program that enabled the screen and keyboard to be accessed via modem at a whopping 300 bps.

In 1981 there were a handful of home microcomputers you could buy, The Trs-80 model III was one of them, also Commodore Pet, Apple I, and a few others. There were enough of them out there and enough board teenagers that war dialing became a common thing and people discovering my word processor sitting on a modem became problematic with them fucking around with our word processing files.

So I wrote a primitive BBS front end that had e-mail, file transfer, some online games, and with the right login and password a drop into the command prompt so legitimate people could get to the word processing files.

Then a fellow I worked with who had a surplus electronics business on the side had some floppy drives that "didn't work", but he only wanted $20 each for them so I bought two and hooked them up and with tracksess found they in fact worked just fine but they were 80tk and double sided which is why he hadn't been able to get them to work. Tandy's operating system, TRS-DOS didn't know double sided or 80tk drives, but NewDOS the OS I was using at the time, did.

So then bought two more, these actually did have defects, one had a bad preamp chip that I replaced, cost me a whole of $4 or so for a replacement chip and the other a bad head select diode. So then equipped with four good drives that could hold 720k each I had almost 3MB which in 1981 was an enormous amount of space for a home computer.

I turned my basic host program into a full featured programming language geared towards writing BBS's which resembled BASIC in syntax but with a different set of keywords geared towards BBS programming. It ran about 40% faster than Microsoft BASIC even though it had more functionality and didn't have some of MS-Basic's bugs like val("%something) causing a crash. I also wrote a secondary tasks that was serviced by timer interrupts that ran into the background that basically maintained a sanity check and rebooted if something was amiss.
It was probably the earliest example of multi-tasking on a Z-80.

I added more functionality to the BBS, an e-mail system, about 100 online games that had save files customized to the user so each user could play a game independent of others.

When Hayes came out with a 1200 baud modem, I upgraded. By 1985 it was so popular that a single line was taking around 300 calls / day. It had also merged with Minibin at this time, taking on Minibin's room oriented message system with the message formatting re-written as part of ComBASIC for speed (all assembly much faster than BASIC). Because Minibin, written by Glenn Gorman, was originally written to use a Microperipherals Bus Decoding modem which was not ported the same as a standard RS-232, and he wanted to sell it commercially but couldn't because the Microperipherals host program was copyrighted, we agreed to adapt each others software to work together and sell it commercially.

By 1985 it was so popular that I decided to go multi-line and so bought a Trs-80 model 16B with Microsoft Xenix as a platform that natively supported multi-tasking. I modified the 16B into the equivalent of a model 6000 and then beyond a 6000 by modifying the CPU board, adding an additional offset and limit register and a patch to the Xenix kernel that a friend back east had worked out. This allowed the CPU board to access up to 7MB of RAM instead of the 1MB it was designed to access.

Then I modified the memory cards from 256k to 1MB by removing the 4116's and adding 4164's and removing the +12V line not required by the 4164's and running an extra address line with blue wire. It wasn't pretty but it worked and allowed me to stuff 4MB into the machine and three serial cards for a total of 11 lines.

In order to cover the cost of lines I started to charge for access. I also bought a couple of 70MB drives, the largest you could get in the interface format supported by the Tandy, so I had a total of 140MB to work with. Added Usenet News and a Telebit modem to support the news feed.

By 1991 the 11 lines were not sufficient for the usage so I bought a Used Sun 3/160 with 16MB of RAM and two Super Eagle 575MB drives. It came with one 16 line MUX, I ordered two more for a total of 48 lines. This soon was not enough. So I bought Annex-3 comm servers and had a total of 256 lines by 1995. By this time I had also added two Sun 4/670MP's with Ross RTK-625 CPUs (125 Mhz Quad Sparc) and a Sun 4/330MP which the telco parted with when they upgraded. The 4/330 became dedicated to processing Usenet News, the 4/670MP one was the mail server, the other shell server.

In 1992 when the Stockton CIX was formed I ordered T1s from Sprint and got on the Internet within about two weeks. Since I already had a local LAN the conversion to Internet was easy, just switch mail to directly talk across the Internet instead of using the Usenet smart routing that it previously was. Back then almost everything was text, text based games were super popular.

Over the years we migrated to Linux, initially on 386 hardware, today mostly overclocked i7 chips. We offer commercial e-mail, web hosting, virtual private servers, and Linux shell access including full remote desktop access to a number of Linux distributions.

Because I have always been an advocate of free speech, in Broadcast or on the Internet where I actually have some opportunity to do something about it, I recently put up a friendica node, this is a node on a federated network known as the fediverse, or the hubzilla network, and there are almost 10,000 nodes and 4 million users. My node talks to other nodes directly so no node can censor traffic for the entire network. As policy I do not censor as long as the material is legal, i.e., no kiddie porn and the like.

I'd like firstly to invite everyone, friendica.eskimo.com/, as a place to freely express your opinions without any threat of being "deplatformed", I am anti-cancel culture here.

Over all these years I've developed a very good hosting platform, Wordpress and other CMS systems are served faster on my platform than any of the big name hosters and I've also modified Apache so that every customers content gets served under their UID so if one customers code is bad it does not compromise other customers.

If you need a stable e-mail address, I've had eskimo.com domain since BEFORE the Internet was (previously routed via UUCP Usenet smart routing network) we can help you. If you need fast secure hosting, we've got the best, and if you would like access to variety of Linux shell servers complete with full graphical desktop we can help you. Check us out at eskimo.com/.

Lastly, in the past I have advertised with Google and Facebook and I've placed advertisement from Google on my site to generate some advertisement revenue but given that Google's changed their position from "Do No Evil" to "Do Only Evil" and Facebook has tossed me off four times now, I no longer wish to give either a single cent of my advertisement revenue, and I am looking for conservative friendly ad networks, so if you can recommend same please let me know.
