Too Much To Do – With Updates

Wednesday, May 16th, 2012

It seems the more time I need to put into prepping, the less time I have available. I’ve cut back on gaming, TV, movies, etc but there just isn’t enough time in the day. I know I’m not alone in this dilemma, and all we can do is muddy through.

I’m still working on my “prepping in 30 minutes a day” system. I’ll have some time this afternoon, and I hope to finish it off, review it and post it this week.

I spent some time in the workshop yesterday. I have been working on resolving a storage dilemma I know most preppers have. How can I store stuff, but have it portable? I’ve been banging away at Google Sketchup designing a way to build a wooden storage box that is stackable, sturdy, lightweight, and can be built from stuff you find in a Big Box store. I built a prototype yesterday, but it was a bit to heavy (about 20 pounds), and a bit too large.  One feature of this design is the height can be customized to whatever you want, the boxes still stack without a problem.

There are commercial alternatives made from plastic that would cost about the same. First, wood will take more abuse than plastic. Wood dings and splinters, where plastic shatters. Secondly, these can be built and repaired post-TEOTWAWKI with hand tools and time. Finally, you cannot access your stuff from the side. My design has one side that can drop down, allowing easy access to the contents, even when stacked floor to ceiling. If you have crates that you don’t want to have that feature, then don’t build them that way.That leads me to the other advantage: build it however you want! I’m planning on building different models.

“Jumbo” – roughly 36w x 22d x 12h – holds six #10 cans, with thin dividers in-between to keep them from getting banged up.Also used for big, but light things like clothes, blankets, gear, etc.

“Bigin” – roughly 20w x 16d x 12h – holds eight 1qt mason jars, or sixteen 1pt mason jars.  Shallower versions of this would be ideal for tools, screws, nuts & bolts, nails, etc.

“Normal” – roughly 16w x 12d x10h – holds 24 cans (beans, veggies, Spaghetti-O’s), ammo, books, magazines, and other heavier items.

When I get a working prototype I will post a full writeup, with plans, and how to build them en masse, to drive costs lower. I expect the sizes to vary some, until I am happy with the weight to contents ratio. I’m shooting for a container that is sturdy enough to hold up to some abuse, but light enough that it isn’t heavier than what it is carrying.

I’m also working on my role post-TEOTWAWKI. I’m anxiously waiting for my body armor to come in. I also have most of my weapon upgrades in, but not all. I’m putting some time and effort into my main weapons platform, my M1A, to improve my performance as a “designated marksman” after the collapse of civilization. While waiting for parts, some of which has taken over three months to get, I’ve been doing some reading and a lot of thinking. I have a post in the works on post-TEOTWAWKI tactics, and expect more tactical homework assignments to illustrate the difference in military and police tactics and what I feel the tactics we should be using post-TEOTWAWKI. The Military’s tactics are centered around taking and controlling ground, with air, artillery, and more importantly logistical and medical support. There is a percentage of “acceptable losses” when executing an attack plan. As a prepper, I don’t want to have to attack anything. This is why I don’t see the weight of my battle rifle as a problem, I don’t have to assault some hill with it and a hundred+ rounds of ammo. I’m holed up in my house with all the ammo I want, but with zero logistical and medical support.

I cannot wait to see how my M1A performs with these modifications! I feel like a kid at Christmas. I could have bought a decked-out M1A from Fulton Armory for $3k+, but I didn’t have $3k to spend. I did drop about $900 in these upgrades. My plan is to circle back when my budget allows and buy a top-notch M1A receiver and barrel from a place like Fulton Armory, and all the other missing bits like op-rod, trigger group, etc and install it into the stock I bought for my “stock” M1A I have now. Then I’ll have dual M1A’s, and can sell the Franken-FAL – my backup battle rifle.

I’m still downloading and evaluating apps for my tablet, and will post my findings soon. I also want to revisit the “survival computer” but avoid all discussion of hardware — it changes way to fast. I want to focus on software you should have and what options you have with your operating system.

Last, but certainly not least, I want to go over a backup procedure for us preppers. You are your data, and having a copy of that easily accessible, but secure, is something we all need.

So I have quite a few articles in the works that I know will be helpful, but time has my butt in a vise and someone is turning the handle.

Business Trips Suck

Friday, August 26th, 2011

Unless you’re going to Las Vegas! WOO!

I’m going to VMworld – the end-all be-all of vitrualization. For a week, Las Vegas will be the geek capital of the universe as IT professionals from around the world revel in all the non-existent computer hardware. For those of you who are not geeks, virtualization is how you get many virtual computer systems to run on one chunk of physical hardware. So many computers who think they are on a physical server, but VMware’s product tricks them into co-existing in parallel, sharing the resources between them.

This upcoming week I’m not going to be able to post much, but on the other hand I’m going to redouble my efforts at writing. I got 11+ hours on a plane, 3+ hours stuck in airports and untold time waiting for the next session to start. I plan to use the time wisely.

While out there I plan on hitting a few of the pawn shops for silver rounds and junk silver. I’m not expecting a great deal, but since the silver mines are out that way, I might get it closer to spot than the scumbags near me who want $5-$10 over spot, and refuse to sell during a dip. I’ll also keep an eye open for useful goodies, if push comes to shove, I’ll ship it home via UPS.

The do have a Fry’s Electronics just off the strip, and I enjoy that place immensely. We do not have anything like them up here in the Northeast, so it’s a real treat to handle your computer hardware before you buy it. I usually just get to look at pictures on Newegg.com and Tigerdirect.com. They always have in-store deals on open box items, and I’m really looking for the cheap USB thumb drives they have. I want to buy a for offline data storage, and information drops.  If the Federal Government sends out jack-booted thugs to stomp on our few remaining freedoms, a thumb drive with Truecrypt can be used to pass information between people. Plus they hold a lot of data in a small space, which is very handy for BOB’s and pre-positioning an offsite backup of your files at your retreat.

Wow, they way people are acting there is a hurricane on the way or something. I’m going to miss it, as my flight leaves tomorrow morning. I have already battened down the hatches at the house, including replacing the batteries in my burglar alarm sensors and the smoke detector. A friend has promised to check on the place, just in case something really weird happens. Thor and Loki are going to stay with my brother. I’m not worried, 70mph winds are not that big a deal, we had a lot worse recently with the windstorms that caused that terrible tornado out west.

For the record writing a short story is much, much harder than a novel — at least for me. I was never a reader of short stories, so my writing is more suited to novel-length fiction. The short story I have been working on, tentatively titled Faith is up to 15,000 words and I’m not even up to the climax of the story. I need to cut out a lot of stuff, or rather, condense it into summary, but keep it readable and engaging. I will remove an entire character and at least three scenes. My revised size is going to be between 12,000 and 15,000 words when completed. I really like the interior and exterior problems of this character and I think the longer format allows the story to be properly set up, revealed, and resolved. No longer a short story, Faith will be a novelette. I could have easily broken through the 17,500 word count to make it a novella, but part of the reason for doing this is to become a better writer.

Another project in the works is a series of posts about building, configuring, etc a survival computer. Please forgive me for being a complete ass, and not providing you guys information that would be really handy. I’m an IT professional with 20+ years of experience, and yet I didn’t take the time to distill that knowledge into something useful for my readers. I toyed with the idea of submitting it to survivalblog.com for the non-fiction contest, but I don’t write this stuff for him, I write it for you. I’ll send him a note that the post is up there, but he’s ignored my e-mails in the past, and I see no reason why that behavior will change. I’m a very small fish in the survivalism/prepper pond, and he’s a busy dude. Plus, I’m not thanking Jesus every five minutes, and I get the impression (translation: not a fact, an opinion) that he’s biased against non-Christians with the articles he posts. (For the noobies out there I’m an agnostic.)

If any readers are in Vegas, drop me a note and maybe we could meet up for lunch. The odds are quite high that many participants of VMworld are preppers. Geeks are used to thinking differently from the sheep. Combine that with  a skewed view of the world, above average intelligence and education, and plenty of Zombie movies and video games and you have a damn good chance that you have a prepper.

A Quick Blog Security Tip

Monday, August 8th, 2011

Ever wonder where someone is from when they post to your blog? Take this example that made it through my spam filter.

I do have a free spam post blocker on the website, and I get between 20-40 spam posts a day that are safely stuffed into the spam folder for removal. This one seemed fishy for two reasons. The first was the commercial site for the link. The second clue was the terrible English, although that cannot be the sole indicator or I would never be allowed to comment anywhere.

So I used this nifty website to find out where they are from:

Pop in the IP from the post intot he search box and Bam! you know where they are from.

The way this works is because blocks of IP addresses are assigned to countries. Every computer on the internet needs a unique IP addess to communicate. There are a few ways around this, the most popular is called NAT (Network Address Translation) which puts a bunch of computers “behind” another to get around the one IP per computer limit, and also for security. The NAT device acts as a filter/translation device, and it’s job is to keep track of who is doing what.

Odds are you have one of these NAT devices in your home right now. The Linksys/Netgear/D-Link wireless router in your home does that for you. The cable company gives you one IP address and the little router lets you have your whole family online.

Anyway, because these addresses are given out in blocks you can protect computer systems with firewalls by adding rules to the firewall that drop packets from countries you know shouldn’t be on your site. For example if you sold devices like weapon sights or encrypted hard drives, then you cannot export these outside the US. So there is no reason anyone from China, Brazil, Russian Federation, Ukraine, or any of the other hacker hotspots need to see your stuff for sale. So you can deny them access.

There is a way around it with software that uses anonymous IP addresses to filter your IP address. The most popular is TOR, which I use on occasion.

I could go on for hours on computer security, the hard part for myself is how to translate the concepts into words that are entertaining, and carry the meaning through to the computer noobie, but doesn’t bore the more experienced users to tears. I will try to post some security posts in byte (ha ha) sized chunks as I can get the time.  I also am working on a more extensive post, maybe a series, that goes into the concept of a “survival computer” and software tools that will help if the bubble goes up.

Virus Warning!

Monday, August 8th, 2011

Do NOT go to WSHTF.COM! They have been infected with a malware infection virus that uses a Acrobat Injection exploit to install some nasty malware in yur system. This might only be on the main page, but I didn’t stick around long enough to figure it out. For the record I did get whacked with the virus and spent three hours restoring the VM from a backup. This is why I use Virtual Machines to browse the web, rather than run naked.

If you have adobe acrobat reader installed then STOP READING AND REMOVE IT RIGHT FREAKING NOW. Adobe has a policy by default that any .pdf you read can execute links to websites to infect your system.  I recommend using Foxit Reader Pro, it’s free and doesn’t update every day or so. Been using them for years, not paid for endorsement, just a product I like.

If you insist on using Adobe reader read this blog post to secure the default settings.

Internet Security HOWTO

Thursday, February 18th, 2010

Let’s cut to the chase. This is a quick primer on how to protect yourself on the internet. Protect yourself from harm on the internet and (to some extent) from governmental snooping.

In order to keep this less than 300 pages of techno-babble, I’m going to keep this on point, and try to keep this more hands-on than theory.

First, if you do not have current anti-virus software, then get it here.

Second, never, and I mean never! connect a computer unprotected to the internet. Unprotected PC’s are attacked and compromised in about an hour. If you must connect a computer directly to the cable modem then the local firewall must be enabled.

Guess it’s time for a quick discussion on how the whole internet works. Every computer on the internet has and address, and each computer has a load of windows and doors for data to come in and out, called ports. These ports are defined and standardized, for example port 80 is for web(http) connections, and port 443 is for secure web(https) connections. Your address is represented by a “dotted quad” for humans (i.e. 72.14.204.103).

A firewall acts as a traffic cop, preventing traffic from getting into or out of your house. Usually these are in the linksys routers you use to connect multiple computers tot he internet. Your cable modem DOES NOT have one. All Unix, and current Mac and PC (xp+) OSes have firewalls, but they are not the best in the world. I could write a whole series on how to configure them. The default settings are better than nothing.

Since you don’t want to remember these numbers, and have to type that number every time you want to go to google, they have a naming resolution system called DNS – Domain Name System. The way DNS works is there are domains that nest inside each other, and by sending the name to a server, you get the dotted quad back. Thankfully, all of this is behind the scenes 99% of the time. The reason this is important is for you to protect yourself you need to know a little on how this works.

The way DNS works is you give it a name like www.google.com, and the DNs server finds the server that runs the “.com” domain, who points you to the server that runs the “.google” part who then gets you the IP address of the “www” part. The leftmost part is the most specific, and the right hand part of the name is the most general.

Since every computer on the internet has an IP address, and that IP address is from your local internet service provider… if you go hack the NSA website and they get your IP, black helicopters know what house to go to. But we have ways of hiding that, more in a few minutes. Hit this website for a demonstration.

Ok, back to practical stuff. Every computer has a local file it uses to find addresses for computers. We can use that to stop malware and other nasty software from calling home. Edit this file and replace it’s contents with the stuff from here. The site has info on how to edit your hosts file.

Next, a word about habits. Never, ever run anything sent to you in an e-mail unless you explicitly trust that person. This includes the funny powerpoint presentations, or excel files or even word docs. There is programming that can be embedded into these documents that act like a virus and can infect your machine. Do not go to any website you do not trust. don’t click on any pop-up ads – ever. Do not download “free” games from pogo, or anywhere else. Sucks don’t it? Only way to be sure you are safe is not to play dangerously. I’ll write another document later on how to build a secure browsing computer.

Next, if anyone has physical access to your computer, then they have compromised it. Set a screen saver with a password- it will stop “drive-by” hacks – the ups guys going to use your bathroom and does something to the pc turned on in the office.

Now to protect your location from snooping you need to anonymize yourself. There is a free network called TOR that protects you from basic web browsing, but it will not protect you from flash, cookies, youtube, etc… There is a good writeup here on what it protects you from – and what it doesn’t. There is a paid subscription service called anonymizer for $30/year that is pretty good, but it is not compatible with IE8 and Firefox 3, so for now it’s useless.

Most of internet security is just having good habits. Once you secure yourself, then always use that security to protect yourself. A Wired magazine writer just had a contest where he tried to disappear, and bad habits got him nabbed. I read a great article about it by the fugitive, but cannot find it, here is the hunter’s story.

Being cognizant of your surroundings applies to the online world too, you know.

Patch your computer

Friday, October 24th, 2008

There is a new windows exploit out in the wild, go to Microsoft.com and patch your computer! All windows versions are affected, if your running anything older than XP you’re screwed.

Details here: Microsoft Security Bulletin MS08-067 – Critical

Rumor has it this will be as bad or worse as ZOTOG which hit three years ago.
