There’s one thing we humans can’t go very long without, and that’s water. Whether the government has forced you to connect to a municipal water supply or you’re concerned that a lack of electrical power might prevent you from pumping water from your existing deep well, it’s certainly worthwhile to know how to create your own shallow well, should you ever need to.
I’m from Florida, where wells are not that complicated and many people have their own wells to supply water to their homes. In many, but not all, areas of Florida, groundwater can be found fairly close to the surface. This would be a great source of hand-pumped H2O in a pinch.
I recently ran across an article at Mother Earth News, in which Al Adams describes his experience designing and building “a do-it-myself shallow well.”
To begin the project, I dug a three-foot-square hole at a point where a natural spring (“seep” might be a more accurate term) was located. I was careful to position my pit back from, and a bit above, a nearby marshy area. (Ideally, a well hole should be dug in late summer, when the water table is at its lowest. At that season you’ll need to bail less while digging and can be reasonably sure of an adequate flow of water during the wetter parts of the year.) I was relieved to hit bedrock at a depth of 5 1/2 feet, since I would have had difficulty excavating deeper with hand tools.
Once the pick-and-shovel work was behind me, I obtained two 55-gallon drums (they had formerly held glue) with locking ring-sealed removable lids. A friend kindly volunteered the use of his oxyacetylene torch, and before long the bottoms of the two barrels were removed and I’d brazed the cylinders together end to end …producing a sturdy steel tube about two feet in diameter and six feet long.
He used a campfire to burn off the old glue and paint from the steel drums, and experienced something that would have ruined his day if he hadn’t been lucky during the torch-cutting process: intense burnoff of the glue residue.
Much to my surprise, a column of yellow flame was soon shooting some 15 feet into the air, accompanied by the earthquake—like rumble of a very violent draft. Within an hour the paint had been vaporized by the intense heat and—after waiting for the metal to cool—I wire-brushed the remaining residue from the metal and rolled the assembly down to the hole.
He next describes how he shoveled in some gravel to filter the water and made a mount for a hand-operated pitcher pump. After pumping out a bunch of mud, he chlorinated the well with bleach.
I also decided to chlorinate the water, to kill any bacteria that might have been introduced during the construction process. To do so, I mixed one quart of household bleach with an equal amount of water, making a solution capable of purifying 100 gallons of drinking liquid. The mixture was then dumped into the well and the system resealed with its locking ring and silicone caulk. I pumped until a strong smell of chlorine was evident at the hose outlet, then let the purifying chemical do its work overnight. On the following morning, I pumped the well out a few more times to remove all detectable traces of bleach. After that my low-cost shallow well was ready for use!
Here’s an addendum from the editors of that site:
Anyone duplicating Mr. Adams’s well might want to consider using only barrels — of heavy plastic or otherwise — that are approved for food storage. The author reports that his metal drums did eventually introduce some rust into the water, which forced him to install a filter. In addition, it’s best to have any new supply of water tested for purity if it’s to be used by humans, and to install a locking assembly on the lid to prevent curious children from opening the well and, perhaps, falling in.
This sounds like a reasonable way to approach the process of creating a shallow well. What do you think?

In this blog, I will show you how to install PMM on Linode as a low-cost database monitoring solution.
Many of my friends use Linode to run their personal sites, as well as small projects. While Linode is no match for Big Cloud providers in features, it is really wonderful when it comes to cost and simplicity: a Linode “nanode” instance offers 1GB of memory, 1 core, 20GB of storage and 1TB of traffic for just $5 a month.
A single Linode instance is powerful enough to use with Percona Monitoring and Management (PMM) to monitor several systems, so I use Linode a lot when I want to demonstrate PMM deployment through Docker, rather than Amazon Marketplace.
Here are step-by-step instructions to get you started with Percona Monitoring and Management (PMM) on Linode in five minutes (or less):
Step 1: Pick the Linode Type, Location and launch it.
Step 2: Name your Linode
This step is optional and is not PMM-related, but you may want to give your Linode an easy-to-remember name instead of something like “linode7796908”. Click on Linode Name and then on “Settings” and enter a name in “Linode Label”.
Step 3: Deploy the Image
Click on Linode Name and then on “Deploy an Image”.
I suggest choosing the latest Ubuntu LTS version and allocating 512MB for the swap file, especially on a Linode with a small amount of memory. Remember to set a strong root password, as Linode allows root password login by default from any IP.
Step 4: Boot Linode
Now prepare the image you need to boot your Linode. Click on the Boot button for that:
Step 5: Login to the system and install Docker
Use your favorite SSH client to login to the Linode you created using “root” user and password you set at Step 3, and install Docker:
apt install docker.io
Step 6: Run PMM Server
Here are detailed instructions to install the PMM Server on Docker. Below are the commands to do basic installation:
docker pull percona/pmm-server:latest docker create -v /opt/prometheus/data -v /opt/consul-data -v /var/lib/mysql -v /var/lib/grafana --name pmm-data percona/pmm-server:latest /bin/true docker run -d -p 80:80 --volumes-from pmm-data --name pmm-server --restart always percona/pmm-server:latest
Note: This deploys PMM Server without authentication. For anything but test usage, you should set a password by following instructions on this page.
You’re done!
You’ve now installed PMM Server and you can see it monitoring itself by going to the server IP with a browser.
Now you can go ahead and install the PMM Client on the nodes you want to monitor!

Deploying PMM on Linode: Your $5-Per-Month Monitoring Solution
It’s easy to enable Amazon RDS remote access when launching an Amazon RDS instance, but there can be many issues. I created this blog as a guide describing the various issues/configurations we might encounter.
As the first step, we need to select a VPC where we will launch our Amazon RDS instance. The default VPC has all the required settings to make the instance remotely available; we just have to enable it by selecting “Yes” at Public accessibility.
For this example, we used the Default VPC and asked AWS to create a new security group.
Once the instance is created, we can connect to the “Endpoint” address:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 |

When AWS creates the security group after we select the option to make it publicly accessible, it appears that AWS takes care of everything. But what if we check the created security groups?
It created a rule to enable incoming traffic, as security group works as a whitelist (it denies everything except the matching rules).
As we can see here, AWS only created the inbound rule for my current IP address, which means once we change IPs or try to connect from another server, it will fail. To get around that, we need to add another rule:
Adding the 0.0.0.0/0 rule opens the port for the world. This is dangerous! Since anyone can try connecting, it’s much better if we can supply a list of IPs or ranges we want enabled for remote access, even from outside of AWS.
To run RDS in a new VPC or in an existing VPC, we need to ensure a couple of things.
The VPC needs to have at least two subnets. We believe this is something Amazon asks so that the VPC is ready if you choose to move to a Multi-AZ master, or to simply spread the read-only instances across multiple AZ for higher availability.
If you want to make the RDS cluster remotely available, we need to attach an IGW (Internet Gateway) to the VPC. If you don’t, it isn’t able to communicate with the outside world. To do that, go to VPC -> Internet gateways and hit “Create Internet Gateway”:
Once it’s created, select “Attach to VPC” and select your VPC.
Still, you won’t be able to reach the internet as we need to add route towards the newly attached internet gateway.
To do that, go to “Route Tables” and select our VPC, and add the following route (0.0.0.0/0 means it’s going to be the default gateway, and all non-internal traffic needs to be routed towards it):
Hit Save. Now the VPC has Internet access, just like AWS’s Default VPC.

How to Enable Amazon RDS Remote Access
We’re not sure, but we think the groundhog crossed the road for the same reason the chicken did. The problem for this one is that he seemed to do it a number of times, interfering with the flow of traffic. Unfortunately for this Maryland rodent, there was a Carroll County sheriff’s deputy there waiting for him on the other side.
The deputy got out of his vehicle to get the groundhog away from the roadway, but the deputy reported that the groundhog was not acting normally.
Maybe the deputy’s more experienced in groundhog behavioral norms that we are, because we’re not sure we could recognize abnormal activity in one of the beasts. But this little guy had been weaving in and out of traffic, so maybe he’d had one too many cocktails before trying to do the responsible thing and walk home.
Anyway, the officer had traffic halted, so the groundhog decided to traverse the roadway one more time.
“Believing the groundhog to be either sick or injured,” the deputy shot the groundhog, and “put the animal down for the public’s safety,” the sheriff’s office said.
As the indecent was captured on video, this will almost surely shut down most of the internet today. If the officer’s identity becomes known, look for threats against his life and those of his family. We haven’t seen an outraged PETA statement yet, but we’re sure they’re busily at work, tapping out a press release.
Here’s the sheriff’s office’s statement on the matter:
“The deputy was travelling on Rt 26 in the area of White Rock Road when he observed traffic backing up along the road. He found that the groundhog in question was walking into the roadway, causing vehicles to stop and creating a hazard. He got out of his vehicle to assess, and as he tried to direct the groundhog off of the roadway, he realized that it was not responding as expected for an animal that was not being cornered or trapped. Believing the groundhog to be either sick or injured, the deputy then put the animal down for the public’s safety.”
More to the point, it took two shots to bring down the groundhog. It seems obvious that the Carroll County Sheriff’s Department is using underpowered firearms, probably something in a 9mm. If they’re going to be facing groundhogs and larger game, they probably need to be carrying something that chambers a round that starts with a 4. Any suggestions?

Maryland Deputy Shooting Groundhog Caught on Video by Motorist

USA – -(Ammoland.com)- President Trump fights for us every day, and we, at the grass roots level, must back him up 100%. We, as gun owners, are very angry, and we need to use our anger to get moving. We call on all of you, to start/continue to fight. We must KEEP THE US SENATE and HOUSE in the 2018 midterms.
The legalized invasion of the President’s attorney should leave no doubt, in your minds, that the LEFT will do anything it can to retain power, damn the consequences, of our nation and our families.
The LEFT is dragging us closer and closer into another civil war. And, we don’t know what’s on the other side of that civil war, and we would rather not find out. We may be armed and ready with all the iron we need, but we do not like, nor want, that violent path. Violence, though, may be the last refuge of the incompetent LEFT, and there are hopefully, still. other paths we have not yet explored.
We all need to know, with certainty, that our phylosophy is fully grounded in truth. We can face down the crazies that are marching in lock step ready to burn our Constitution, with nothing more than our resolve of the certainty of our love of the US Constitution.
But, right now, we are divided by ignorance. A report by Steven Shepard finds firm evidence that Republicans do favor stronger gun control laws. Of the responders to a Politico poll, 68% are in favor of another ban on “assault rifles.”
Here is a recent Quinnipiac Poll, Table Number 57 gives the stats on an “assault weapons ban”, by age, sex, party and education, and also gives trending data. A total of 67% support such a useless ban on assault weapons. PLEASE REALIZE, THESE NUMBERS REPESENTR US! WE ARE THOSE STATS! Why?
One gun owner, “inspired” by the Marjory Stoneman Douglas High School shooting, went so far as to destroy his AR 10 and AR 15 in a very public way. Folks, this is our people, a gun owner!
Do we blame this situation on our own ignorance? We do not all know all the details, and so we let the devil do his work. To cure this, we must all learn to teach our brethren. We all have to correct these weak and insecure gun owners. We must join together to strengthen our group.
It’s time to get to work. NOW!
If everyone around you knew the truth about so-called “assault rifles” all the polls, faked or not, would reflect a greater sanity.
If you, and your friends, think you know everything you need to know, then you must ask why does your county or state still have any gun laws that are based on bias and racism? If you didn’t know, that is the origin of weapons laws. Why does your locality have such laws, especially if you all know the truth? Find your comfortable place, and spread the truth that frees us from the LEFT.
Gun laws that affect the law abiding do not work. In fact, gun laws may even be counterproductive, like the Gun Free School Zones Act. So, we really have to admit some ignorance on the subject.
Let’s start with the term “assault rifles.” That term didn’t just start when Trump was nominated. The LEFT has been messing with gun truths for decades. They twisted the truth to confuse, and frighten, the masses about “rifles.” And even some gun owners bought the lies. To the LEFT, almost anything beyond a single-shot, bolt action rifle, is an “assault rifle.”
Joe Tartaro, a long time Second Amendment proponent, and author, explained what happened in his article, ‘The Great Assault Weapon Hoax.’ He wrote;
“The push to ban scary looking guns is a conjuring trick devised by devout anti-gunners in and out of government who will settle for banning some guns on their way to banning them all.”
Tartaro discusses tactics of deceit such as suppressing evidence and the attempt to show on TV that ammo from the targeted weapons was more powerful by shooting an exploding melon.
Here’s what happened. Josh Sugarman, of the Violence Policy Center, deliberately created a fabricated fraud, as great as the Trump-Russia Collusion Hoax , which our President is now battling. Sugarman, and his ilk, thinks that it’s OK to lie to people to make them act against their own best interests.
According to David Kopel, Sugarman suggested, and normalized, in to the public discussion, words and phrases such as, but not limited to: , assault weapons, armor_piercing bullets, machine guns, plastic guns, etc. He made them as daily usage. The rifles became menacing looking, and Sugarman coupled that with the public’s confusion over fully automatic guns versus ordinary semi-automatic rifles, cause they looked similar. All this increased the chance of public support for restrictions on these rifles. And the lying LEFT media pushes these norm’d words and phrases.
David Kopel explains that this misinformation still remains as part of American culture. But we gun owners should all know that there is a difference between full auto and semi auto firearms. Aaron Blake explains the bait-and- switch language deception.
So, our nation happily accepted a ten year “assault weapons ban” in 1994. The ban was not renewed because even anti gun researchers could not find any statistical benefit. The government report is here, and some additional information is here.
While this may not become law soon, there will be media hype designed to confuse and mislead the public, and it will boost their fear of guns. They think they can get a better start on banning semi-autos this time around because of the school massacres.
We are not attempting to deal fully with the topic of “assault weapons” lies, but to give you a place to jump start a local discussion group for all who are interested. You can start with the articles linked to in this piece, and we suggest that you make a library of gun truths for future reference.
There is no safety in disarmament. Gun laws only affect the law abiding. The black market trumps all restrictive laws and only outlaws keep their guns.
The law abiding gun owners should not accept the stupidity of the masses and the contempt of the power mongers. Let’s get teaching, and educating our family and friends.
Next time, we hope to discuss the lies surrounding the NICS checks system.

Today, Netflix released a trailer for the second season of Marvel’s Luke Cage, the story of a bulletproof man (Mike Colter) who is fighting to save Harlem from forces that want to do the local population harm. The second season premieres on Netflix on June 22nd.
In the trailer, viewers can see that Luke Cage is no longer operating in the shadows; he’s become a hero to the people of Harlem. He attracts the notice of a new villain, who seems to be just as indestructible as Luke. According to the press release, Luke will need to “confront the fine line that separates a hero from a villain.” It seems as though this season will force Luke to test the boundaries of his own principles in order to defeat this new enemy.
The trailer also gives the viewer glimpses of Claire Temple (Rosario Dawson), who seems to be a sort of conscience for Luke in this season. Misty Knight (Simone Missick) is sporting the prosthetic arm that she is famous for in the comics, while Mariah (Alfre Woodard) is clearly up to no good once again. The premiere episode of the second season is directed by Lucy Liu.
