How To Securely Update A Device

There are two basic types of devices, an embedded system, and a general system.

There are embedded systems everywhere. Your smart TV. The Chromecast you have attached to your “dumb” TV. Your coffee maker, your washing machine or drier.

These are a few of the embedded systems you use every day. There are some that are “critical” systems. Your car, likely, has an embedded system. If that system were to be modified, it could cause “bad things” to happen.

Medical devices are also considered to be critical systems. The computers that control your IV medical drip, even the automatic blood pressure machines or any of the machines that are used for monitoring are critical.

While the blood O2 monitor, attached to your finger, might not seem critical, if the values it is reporting are in error, your health care professional (doctor) could miss diagnose something.

Other examples of critical systems include: many military computer systems, voting systems, systems processing classified information, alarm systems, spacecraft control systems.

Your computer and laptop are not normally considered to be embedded systems, yet they have a part that is embedded. That is the BIOS on your computer and laptops.

Your phone and tablets are a sort of hybrid, where a large part is embedded, but there is an easy way to add other software.

Bread baking in a wood fired beehive oven

The Weekly Feast – Bread

Bread is often called the “staff of life,” and that’s because a man can survive on bread and water. We think of this, in today’s world of Wonderbread and fake food, as a cruel punishment. In medieval times, bread and water was fairly standard fare for a person. In the 1750s, bread was 60% of the average colonist’s daily food intake. Today, that would be considered outrageous and possibly dangerous. Then, the wheat was whole, and even when finely ground (very doable along the many rivers in water-powered mills), it contained all of the natural protein and fat of the kernel.

This recipe is one that I’ve developed on my own. It’s a blend of several recipes that I’ve worked on over the years. It combines a pain de mie recipe, a no-knead recipe that I love, and the “beginner’s loaf”  from a book of Chris’s, Bread Alone. It’s the culmination of about 20 years of practice, learning, failures, successes, and surprises as I learned enough about bread baking to casually consider teaching myself to use a wood fired beehive oven at the Fort.

This is not an easy recipe. It is a simple recipe, however. The beginner bread recipe I mention above is the best place to go for instructions on how to bake bread. If you do what the authors tell you, you will eventually make amazing loaves of bread, every time. It will take a few years of practice, though, and you will probably make up new swear words as you go along. This recipe here, is not as difficult as the beginner loaf, but will not teach you as much about baking as you make it. I heartily encourage you to make it entirely by hand at least a half dozen to a dozen times before indulging in the use of a MixMaster or other bread making machine. Getting your hands onto fresh dough is good for you mentally, and the resulting bread will feed you physically and spiritually. There’s definitely something “more than human” about creating a loaf of bread.

Cognitive Dissonance

The theory of cognitive dissonance proposes that people are averse to inconsistencies within their own minds. It offers one explanation for why people sometimes make an effort to adjust their thinking when their own thoughts, words, or behaviors seem to clash with each other.
Cognitive Dissonance | Psychology Today, (last visited Jul. 21, 2024)

Ok, but what does that mean? More importantly, what does it mean to us?

To get an example of cognitive dissonance in “practice”, dig up “I Mudd” from Star Trek. At the end, the crew destroys the androids by setting up cognitive dissonance in their “logical” brains.

One such method was Spock saying to one android “I love you”, and to another, identical android “But I hate you.” When the androids point out that they are identical, Spock replies, “Exactly.”

The left has been trained to exist in a state of cognitive dissonance.

What comes first?

One of the most interesting things I’m currently discovering, is how to move back in time. What happens when there is no electricity? What can we do, how can we do it?

One path is to learn how to live off-grid. This is part of where I am. This is why I spent the time learning how to make a steam expansion engine, learning how to run it, and then learned how to build a 2 HP boiler.

That steam engine is intended to run a generator or a lathe, depending. Yes, I have some generators, but water and wood will be easier, in some situations, to get than other fuel.

But there is another entire type of skill set, that of taking a step back in time.

Let me discuss just one part of this, I want to make some items, such as a table-top. That’s easy, just drive to the lumberyard and buy the lumber, do the glue-up, feed it through the plainer, sand it and a bit more. Easy stuff.

Prepping for What?

I posted about prepping a bit back on GFZ. I think it’s a topic that needs to be covered on a regular basis, and even if you have been doing it for a dog’s age, the reminders help get you in the right head space. Now, I don’t do the whole “deep state bunker prep” thing. First, I don’t believe the world will go into that much chaos, that quickly. It’s going to be a slow decline (and in my very strong opinion, the pandemic proved that). Second, and more importantly, bunker prep isn’t sustainable.

I don’t know if any of you have watched Love, Death, and Robots (it’s on Netflix if you haven’t, and it’s well worth the watch), but there’s a couple of fairly amazing shorts that cover prepping topics. The one I’m personally thinking of is in season 2, when the three robot friends are touring America after the death of all the humans. They walk around an area where a bunch of people lived in bunkers. They’re all dead, too. Another show, can’t remember the name of it, shows a couple who stays two years in their bunker, and when they open the door they find out that the entire Earth has been destroyed and they’re just floating around on a chunk of ground. These both illustrate the problem with bunker prep.

If you set up a bunker for short term emergencies, that’s fine. It is not, however, a solution for surviving TEOTWAWKI. Eventually, you run out of food, water, or air. And then you die. Bunkers, pre-pack food (like MREs or emergency buckets), and hoarding ammo and firearms are basically just a way to die painfully and slowly.

Real prepping (yes, I said what I said) is learning enough skills to survive after TEOTWAWKI. Real preppers don’t waste time figuring out ways to try and survive a planet buster bomb or other doomsday scenarios, because there’s no point. If the planet is destroyed, you’re just going to die. If a plague comes through and you catch it, you’re possibly going to die. If someone bombs your city, you may die. These are not things to prep FOR.

Prepping is what you do after you survive. Yes, have a bunch of food stores set up, because that’s important. There might not be a grocery store to go visit, or it might be empty, or being run by a despot (who isn’t the current government). You may need to shelter to avoid a firestorm or waves of nuclear fallout or insurgents or invaders. That’s short term stuff.

After the firestorm or fallout or aliens move on, you’ll come out of your hidey hole, and then the real work begins. Surviving is easy. Living is a lot more complex and difficult.

I’ve talked about it before, saving seeds, learning skills, putting food up that’s shelf stable, making short, medium, and long term plans for emergencies. But how to you go about it all? There’s no one answer for how to prep for surviving and thriving. You have to come up with your own plan, that fits your family and your part of the world. The emergencies that I plan for likely aren’t the ones that should be planned for in a big city like Boston or NYC, for instance. I live in the boonies, and there are other issues I’ll have to deal with. City people will have to deal with zombies (the name for those who wander about robbing and pillaging during emergencies) and rationing and figuring out how and when to escape. People near the equator will have to plan for hot weather, and people farther north will have to plan for cold winters, possibly without electricity or dinosaur squeezings.

Friday Feedback

The big news of the week is, of course, that somebody got close enough to Trump to make a real attempt to kill him.

This has opened up a floodgate of horrible responses from people on the rightleft. Listening to Allyson drop people from her friends list on social media has been almost terrifying in its intensity.

Libs Of TikTok has made it a personal mission to expose many of the people who are calling for the assassination of Trump.

I think the most vile thing I’ve seen are “Hopes and Prayers for the shooter and his family.”

Allyson is dealing with a massive shift in politics. I’ve described it as she was standing in the ocean near the shore. Suddenly, the waters just swept out, leaving her standing on shore with all the rest of the right.

It is frightening to her. I’m not so sure of how much she has changed, though she has, but how much the left has just lost it.

I’m trying to figure out this X thing. I want to have each post automaticity go to X but the autopost isn’t working for scheduled posts and when it does post, it is a pretty sad-looking post.

Thank you to every one of you that is here reading our ramblings.

If you would like to contribute to the blog, please send your article to me, and I’ll see if it fits and can be published.

I’m attempting to tone back my case analysis postings to be more readable to humans. Please let me know if the tone is about right for you.

Finally, we will be opening a web store soon. We will be selling Allyson’s books, signed. If anybody is interested in the wooden bowls, I’ll put some of those up for sale as well.

Anybody who is in the NH, MA, VT area that wants to meet at the Fort at #4, reach out to me, and we’ll make it happen.

Have a wonderful weekend.

Be Gentle With Me…

Allyson, sans glasses, in a silly hat

Allyson walks to the podium at the head of the crowded room and looks at everyone. She straightens her tank top unnecessarily, shuffles her feet a bit, and then leans against the podium and adjusts the microphone. 

Hi. My name is Allyson, and I’m a new Conservative.

Hi, Allyson!

The past few days have really changed my mind on a number of subjects. I’m still not a huge Trump fan, but after watching what happened on Saturday, many of my previous concerns have waned. I’ve been reading and educating myself, listening to others, and generally trying to get a better grip on the whole political situation going on. I’ve taken another step to the Right, and while I still consider myself a “small L libertarian,” I think that by society’s standards, I’m now a Conservative.

This is going to be a real ramble of a blog entry, so bear with me. Please.

That puts me in a weird place. I feel like I can’t tell my friends. I haven’t been able to talk politics with them in ages, but it’s been a relatively comfortable silence on both parts. But this? I can’t tell them I’m “on the Trump train.” I’d be ostracized. And yes, I know how that sounds, and yes, that’s part of why I took the step to the Right.

I’m going to say this now, because I have to. I have watched the videos of the assassination attempt a good 40 or 50 times. I’ve looked at different angles, read experts’ opinions, and done my best to do due diligence. The timing and way this played out FEELS too convenient and too well done, and I am absolutely terrified that this was a fake out by Trump and/or his team. My thinking brain tells me that no one, not even the most brash person ever, would have a live bullet come that close to their head on purpose. But my lizard brain is still concerned that somehow, this was just a fake out.

A lot of people have changed their mind about Trump because of Saturday’s attempt on his life. I desperately hope that everything I saw was real (not that I wanted an attempt on his life, but just that the situation as presented is real). If it turns out to be some kind of fake out, I suspect I’ll just walk away entirely and stop dealing with politics. I don’t think I’ll be able to handle it.
