I learned about this cool little Pyro Creations device from a TAOFLEDERMAUS video. This is a miniature cannon that fires muzzle loaded projectiles powered by breech loaded 209 shotgun primers. The reason it is called 3 in 1 is that it can be equipped with one of the three barrels of .17, .22 or .30 caliber.
In order to load the Trigger Cannon, you need to unscrew the barrel, pull the tail of the striker until the pinhole is exposed and place the safety/trigger pin into the hole, load the projectile of the proper caliber, load the shotgun primer and thread the loaded barrel back into the main body of the cannon. Now your artillery piece is ready to send some lead downrange. All you need is to pull the safety pin out.
Below you can find the mentioned TAOFLEDERMAUS video, where you can see how the Trigger Cannon works and learn about what the shells fired from this nano gun are capable of.
The elevation of the cannon can be fixed by tightening the two hex screws holding the cannon to the bed. There is also a hole drilled in the base of the bed that will allow you to attach the Trigger Cannon to a board via a wood screw.
Here is also a video found on Pyro Creations website.
Now, bear in mind that this cute little cannon is not a toy and you should apply the firearm safety rules to this micro artillery piece, too.
The Pyro Creations 3 in 1 Trigger Cannon comes with black or silver barrel color options and red, blue, black or gun metal colored beds. It is listed on the company’s website at an MSRP of $49.99. It comes standard with a .22 caliber barrel and a ramrod. The .17 and .30 caliber barrels are sold separately at a price of $14.95 each or $23.95 for the set of two barrels.

So you want to make your own hot sauce
FeaturesStories from The Takeout about food, drink, and how we live. I love hot sauce. I use it on almost every meal: pho, sandwiches, pizza, nachos. As Ethel so kindly states in a Frank’s Red Hot commercial, “I put that shit on everything.” I’ve got about a dozen bottles in my fridge, each with their own distinct flavors and heat levels.
I’m also an avid home cook. One of my goals this year is to cook through an entire cookbook, Alton Brown’s EveryDayCook Cookbook, and I’ve even been compiling recipes for my own family cookbook over the past couple years. But combining my love of hot sauce and cooking—making my own hot sauce—never crossed my mind, for some reason. Maybe I always saw it as a store-bought condiment, not a recipe? Who knows. I figured I’d try it out and see how bad I could mess it up. Turns out, it’s much easier than I thought.
I grew up in a family of chefs. My mom doesn’t even look at recipes to make delicious food—a skill I’m slowly learning—and my dad worked as a chef in the Army on his first tour of duty. So it’s in my blood to see a meal and try to figure out all the moving parts. This, however, can lead to me overthinking meals, making them seem more complicated than they are. I always looked at hot sauce bottles and thought “Just five or six ingredients? Must be a complicated process.” It might be for some of the more advanced recipes, but for a basic hot sauce, it’s not.
What do I need to start?
A recipe, first and foremost. I perused r/hotsauce and was led to a recipe on r/hotsaucerecipes. I wanted something simple. Nomzai presented the perfect option. This was an early crack at hot sauce so I didn’t want to get too fancy with fermentation and give myself botulism or something.
You’ll need vinegar, which forms the base of most sauces. You’ll need salt. And obviously, you’ll need peppers. The most time-consuming ingredient was sautéed garlic, which says a lot about how easy the recipe is—simply throw everything into a blender and whazz it up. Beyond that, it’s all in the recipe or in your imagination. Hot sauces can be changed by more than just pepper choices. Some sauces, like Rick Bayless’ habanero sauce, uses apple cider vinegar. Tropical sauces are typically full of pineapple, mango, and even bananas.
Do I really need gloves?
Yes.
If you’ve never experienced pepper burns before, they’re plainly terrible. In my experience, there’s no blister or even reddened skin, but it’ll hurt for a few hours at least. Even jalapeños can leave a stinging sensation on your hands for the rest of the day.
The recipe I used included habanero peppers, at least 10 times hotter than jalapeños according to the Scoville scale, so I wasn’t about to mess around without some protection. And please, for your sake and mine, keep your hands away from your eyes, nose, ears or any other sensitive part of your body until you wash your hands with dish soap. Even if you used gloves.
Won’t my sauce go bad?
The more acidic your sauce is, the longer it’ll ward off bacteria, mold, and other organisms that can make you sick. Vinegar is acidic, about 2.4 on the pH scale. Peppers are acidic. The sauce I made was full of citrus—grapefruit, lime, and orange—so that’s even more acid. So if I wanted to, I’m sure I could keep the sauce for a few weeks or longer. That said, I’m quite skittish about getting sick from food after a bout of food poisoning last year (I can still barely look at shakshuka), so I’m more than happy to devour the sauce in a week or two.
As a middling homebrewer, I know the importance of keeping all your vessels clean. It wouldn’t hurt to run the container you plan to use through the dishwasher. At the very least, use some strong dish soap and clean it by hand. Or, if you’ve got some in a cabinet somewhere, mix up a StarSan solution and dip the vessel in there.
All this said, if you start seeing some growth happening in the bottle or jar you’re using, just toss it. New bottles are cheap and it’s not worth the risk unless you really know what you’re doing.
What are the best peppers to use?
This is entirely up to you. I’m a big fan of the heat level and fruity flavors of habanero peppers, so I used a handful of those. Habaneros are also cheap. They go for about $5 a pound at my local market and I used less than a quarter pound of them to make this sauce.
If you like smokier sauces, go to your local Mexican market and grab some dried peppers. Smaller peppers tend to work best in the blender. I used chile de arbol for this recipe and they beefed up the spice, color, and smoky quality of the sauce in a lovely way. Just make sure you reconstitute the dried peppers by placing them in hot water for a half hour or so. Otherwise, you’ll end up with a plume of pepper powder flying out of your blender.
If you’re like me and want to limit the spiciness of your first sauce, don’t be afraid to use a few sweet peppers. They brightened up the sauce I made, in terms of both flavor and visuals.
What would I change?
My only regret with this sauce is that it’s runnier than the rest of the sauces in my fridge. A lot of hot sauce companies use xanthan gum to thicken their products (Brooklyn’s Heatonist shop famously doesn’t sell sauces with xanthan gum, if you’re looking for such a thing), but I didn’t want to mess with an ingredient I didn’t know much about on my first try.
Looking back, I’d have kept more pulp from the citrus fruits I used and I’d have run the blender about half as much. I’m sure I could have used less juice from the orange, grapefruit and limes, but I really enjoy the tropical flavors they give. I’d also love to play around with ground cumin or cayenne next time. Luckily, the basics of hot-sauce making are inexpensive and low-stakes.
Procedurally, I also would not have opened the blender right after mixing it and taken a big whiff. I basically pepper-sprayed myself (fun fact: I did that with the real stuff when I was 3 or 4 years old). Be patient and give it a second to settle before inhaling.
What are the best resources?
I’m a grateful member of r/hotsauce, and I find a lot of recipes on there and other hot sauce related subreddits, but the best resource for me is hot sauce itself. Figure out what flavors you enjoy—I want to add cumin and cayenne—which peppers your favorite sauces are made from—I’m trying scotch bonnets next—and use your imagination to create new flavors and new experiences.
Keep everything clean and keep your hands away from your face, trust yourself, and figure out what you like. I didn’t get everything perfect my first time, but I learned for the next attempt. And I certainly realized how easy it is to get started.

How to Format a Write Protected USB Flash Drive
You’re trying to save data on your USB flash storage, but there’s a problem. Any attempt to save displays the message that the drive is “write protected”. How can this be?
The drive won’t even allow you to reformat it, and there’s no apparent switch for enabling or disabling write protection. Puzzled? Here’s how to format your write protected USB flash drive and start using it again.
Is the USB Drive Write Protected or Corrupted?
Before proceeding, take the time to make sure that the drive is genuinely write protected. A couple of other issues could be coming into play here.
- Your PC’s USB port is defective or blown entirely. Fixing a damaged USB port can be tricky but not impossible.
- The flash drive is corrupt. Whether you’re using a full USB flash stick or USB SD card adapter, problems with the device can occur. These steps will help you fix a corrupted flash drive.
Confident the problem is just write protection on your USB flash stick? Let’s move on.
How to Remove USB Write Protection With Diskpart
Before starting, insert your USB flash drive into your computer’s USB port.
Windows has a built-in disk partition management tool called Diskpart. You can open this by hitting Windows key + R, entering cmd, then hitting Enter.
User Access Control will prompt you to confirm the action. Click Yes to continue.
You should now see CMD, the command line tool. At the prompt, enter
diskpartA new command line window will open, with a new DISKPART prompt. It’s time to see which disks are attached to your computer:
list diskThe resulting table will list the currently available devices. But which is your USB drive?
Disk 0 will be your computer’s system drive. This is the one that Windows is installed on. If you have multiple partitions, these will be sequentially numbered. Note that the size is displayed for each disk.
With a USB flash device connected, (which will be Disk 1 or higher) you should be able to identify it by its comparatively low capacity.
In the image above, while Disk 0 is 119GB and Disk 1 931GB (two partitions of the same drive), Disk 2 is 16GB.
Therefore, Disk 2 is the USB flash drive. You should be able to check the capacity on the device itself, as this is usually printed on a drive’s casing. If not, you’ll be able to confirm it in Windows Explorer.
Select the Right Disk!
Before proceeding further, be absolutely certain that you have identified the USB flash drive. Note also that USB flash drives can be as high as 1TB in capacity (like the PNY Pro Elite) at the time of writing, which could be larger than your computer’s HDD. Making the effort to be totally certain at this stage is vital to the integrity of the data on your computer!

Build Your Own Glock Series with TFB
The Firearm Blog has partnered with Lone Wolf Distributors to bring you a series on building your own Glock. Buying an 80% receiver is not new to the gun industry. Glocks are the rage, why not build one the way YOU want it? Get yourself a hot gat, and loose that Fudd factory gun. Get that sweet trigger in there, and pay no attention to the factory fanboys. (Factory purest click here)
I looked at my Gen 2 Glock 21 and figured she is probably ready to retire to safe queen status, therefore, clearly time for my next Glock. I already own a (cough) number of Glocks, but I decided this has to be a hot gat. Rather than paying top dollar for a pimped out Glock, I want to build exactly what I want the way I want.
Taking an 80% receiver is perfectly legal, and surprisingly common. I know of a retired military operator who has built a half dozen and working on another. In this series, I will be building my pimped out Glock 19. RMR ready and eventually suppressed.
So dear reader hit that link below, visit Lone Wolf, get yourself an 80% receiver and join us for this surprisingly easy adventure in building yourself a Glock. If it is for a Glock, these guys have it.
Everything you will ever need for your Glock. Check them out.
What You Will Need
- 80% polymer Frame Kit (here) Lone Wolf will also supply you with a “completion kit” that will throw in everything you need for the lower (see here)
- Slide
- Slide completion kit (see here)
- Barrel
- Drill Press
The 80% frame will arrive in the jig you will use to remove the material to bring the frame to 100%. It also ships with the drill bits required. I will go over all of this in the series, step by step.
Next addition I will briefly address the legality, as I sat down with an ATF agent before I started. A very cool guy who helped me out with pitfalls people run into. Then I will start creating my new sweet non-factory Glock.
I know there a lot of you who have already built up an 80% frame. What do you think? How was your experience? Let us know below

MySQL Error: Too many connections!
When your application get error "too many connections" underlying problem might be caused by multiple things.
In this blog we will investigate why and how to solve these problems when running MySQL installed on Debian/Ubuntu using systemd (default MySQL packages).
OS: Debian 9
MySQL Server version: 5.7.25 MySQL Community Server (GPL)
(will most likely be the same for MySQL 8.0 versions)
Goal is to have 10.000 working connections to MySQL!
The default value for max_connections is 151 connections so first step is to increase the max_connections variable to 10.000.
This is documented in the manuals here:
– https://ift.tt/23yLjHw
– https://ift.tt/2FNe7om
The max_connections is a dynamic setting so lets increase value to 10.000 and see what happens.
|
root@debian:~# mysql -uroot -proot -se "select @@max_connections" @@max_connections 214 |
Hmmm, it looks like we only got 214 connections, lets look at the error log:
|
2019-04-01T06:29:48.301871Z 0 [Warning] Changed limits: max_open_files: 1024 (requested 50000) 2019-04-01T06:29:48.302000Z 0 [Warning] Changed limits: max_connections: 214 (requested 10000) 2019-04-01T06:29:48.302004Z 0 [Warning] Changed limits: table_open_cache: 400 (requested 2000) |
Looks like we hit some resource limit.
Lets look in the MySQL manual for running MySQL under systemd, that can be found here.
Looks like we need to increase the number of allowed open files for MySQL, locate the systemd configuration file for MySQL and create the /etc/systemd/system/mysqld.service.d/override.conf (file can be called anything ending with .conf).
Add LimitNOFILE=10000 in file override.conf like:
|
root@debian:~# cat /etc/systemd/system/mysql.service.d/override.conf [Service] LimitNOFILE=10000 |
After this we need to reload the systmed daemon and restart the MySQL service like:
|
root@debian:~# systemctl daemon-reload root@debian:~# systemctl restart mysql |
MySQL is now saying we have 9190 connections:
|
root@debian:~# mysql -uroot -proot -se "select @@max_connections" @@max_connections 9190 |
So, MySQL is using some files for additional work and we need to set this a bit higher to get 10.000 connections, lets set it to 11.000 and reload the systemd daemon and restart the MySQL service.
|
root@debian:~# mysql -uroot -proot -se "select @@max_connections" mysql: [Warning] Using a password on the command line interface can be insecure. @@max_connections 10000 |
Good, now we have 10.000 connections available according to MySQL.
Lets run our application and verify we can get 10.000 connections, I use this small perl script to open 10.000 connections.
Just below 5.000 connection I get a new error in the application "Can’t create a new thread (errno 11)"
Lets have a look at the MySQL error log:
|
root@debian:~# tail -1 /var/log/mysql/error.log 2019-04-01T06:50:35.657397Z 0 [ERROR] Can’t create thread to handle new connection(errno= 11) |
I found this new limit by running command below when perl script was running:
watch -n.5 "mysql -uroot -proot -se’show status like \"%threads%\"’"
Strange, where is this new limitation just below 5.000 connections coming from?
Looking at resource limits for my MySQL daemon I should have close to 8000 processes:
|
root@debian:~# cat /proc/$( pgrep -o mysql )/limits Max processes 7929 7929 processes Max open files 11000 11000 files |
Lets looks at status report for my MySQL service:
|
root@debian:~# systemctl status mysql | grep Tasks Tasks: 127 (limit: 4915) |
There seem to be some additional limit on Tasks that limit me to 4915 connections.
Lets expand our override.conf configuration to cover for 11.000 tasks also.
|
root@debian:~# cat /etc/systemd/system/mysql.service.d/ [Service] LimitNOFILE=11000 TasksMax=11000 |
(remember to reload systemd and restart MySQL service after each change in override.conf)
Now we got just under 8.000 connection and got the same error " Can’t create a new thread (errno 11)" but this time it’s because of the limit of max processes:
|
root@debian:~# cat /proc/$( pgrep -o mysql )/limits Max processes 7929 7929 processes |
Lets increase this limit to 11000 in our override.conf:
|
root@debian:~# cat /etc/systemd/system/mysql.service.d/override.conf and [Service] LimitNOFILE=11000 LimitNPROC=11000 TasksMax=11000 |
After reloading systemd configuration and restarting MySQL service I can now get
10.000 connections and the perl script runs without any errors!
Summary:
There are different limits when setting max_connections in MySQL:
– The default max connections is 151.
– At 214 connections you are limited by max open files.
– At 4915 you are limited by Max Tasks (systemd)
– Just below 8000 you are limited by max number of processes
By adding a override file (as showed above) you can overcome all these limits.
Remember to:
Look at error message in application and MySQL error logs.
Look at output from: cat /proc/$( pgrep -o mysql )/limits
Look at output from: systemctl status mysql
Test your application (or use my perl script) and monitor that it works!
Monitor how many connections you have: watch -n.5 "mysql -uroot -proot -se’show status like \"Threads_connected\"’"
