Previously on The Rimfire Report, we briefly went over a shooting sport conducted during the winter Olympics – The Biathlon. However, the summer Olympics has its own set of shooting sports which include both rimfire rifles and pistols. Today we’ll briefly go over some of the rules, equipment, and disciplines involved in the Shooting Sports for the upcoming 2020 Summer Olympics being hosted at the Asaka Shooting range in Japan. Olympic Rimfire sports have a long history dating back to the beginning of the modern games in 1896.

25 Meter Rapid Fire Pistol

As the name implies, this competition involves shooting at a 25-meter distance with a pistol, specifically a rimfire pistol. The 25 Meter Rapid Fire Pistol event is derived from the ISSF (International Sport Shooting Federation). The ISSF also recognizes several other Olympic shooting sports including events involving shotguns.

This 25-meter Rapid Fire Pistol event is always shot with .22 LR pistols. Competitors will use their highly specialized pistols to engage a target with 5 shots. Each set of 5 shots constitutes a string and is graded by accuracy. Each target must be engaged using only one hand, making the shots incredibly difficult to master.

Competitors start from a “low and ready” position that is 45 degrees down from their starting position. There are three different time limits for the series: 8 seconds, 6 seconds, and 4 seconds. A stage consists of two series of each type, and a full course of fire comprises two such stages or a total of 60 shots. Since the targets are divided into concentric score zones with 10 being the most central part, the total maximum score is 600. Iron sights are the only sights that are used in the Olympic 25 Meter Rapid Fire competition.

6 finalists eventually go on to compete in an elimination-style match which includes their cumulative score until the winner is determined after 8 total strings (series) and 40 shots.

25 Meter Rapid Fire Pistol History

25 Meter Rapid Fire Pistol has been a part of the Olympic games as far back as 1896. The Rules changed significantly over time, especially before WWII. Some of the changes came at the expense of performance however as in 2005 new rules were put in place that restricted the types of grips and trigger pull weights that were legal to use. In 1989 the sport also banned the use of .22 Short cartridges under the blanket rule change of limiting the competition to “Sport Pistols” only.

This series of rule changes saw companies like Walther making bids to design completely new pistols to conform to the requirements of the Olympic sport and ISSF. One such pistol – the Walther SSP is an extremely odd-looking pistol. The SSP replaced the OSP which was rendered obsolete by the rule changes in 2005.

The Walther SSP makes use of detachable 5 round magazines, weighs 34 oz, has a 6-inch barrel and features an extremely light 2.2 lb (or 1000 gram) trigger pull. If you’re looking to get into Olympic pistol competitions, one of these pistols will set you back $2,095.00 just to start, and this doesn’t include years of training or magazines – and all that ammo you’ll be practicing with.

50 MEter Rifle Three Positions

This three-position competition involves shooting from a standing, kneeling and prone position during the course of fire. During the event, each competitor must complete the course of fire within a limited time frame of 2 hours and 45 minutes. Naturally, only .22 LR rimfire rifles are used.

The target used is a 6 inch black and white target with several rings used for grading the accuracy of the shooter. The target is placed at a fixed height above the floor of the shooting range at .75 meters or just under 2.5 feet.

Until recently, men and women competed by different standards with women’s competitions tending to be shorter and with shorter courses of fire. Each course of fire follows in the following order: Kneeling – 40 shots, Prone – 40 shots and Standing – 40 shots. This is considered a qualification course of fire. Following the qualification round, the top 8 shooters will fire an additional 10 shots one at a time in the standing position. The winner of the match is the shooter with the highest score from both the qualification and final rounds.

Olympic Rimfire Rifles used in the 50 meter three position

Rifles used in the three-position target match tend to be made by three competing companies. Anschutz makes many rifles used in this competition as well as the Biathlon. Feinwerkbau and Walther also make rifles in the rimfire target category and it goes without saying that all three options cost quite a bit even at their base price.

Where in biathlon competitions you are striving for the lightest rig possible for skiing, in the 50 Meter Three-position weight is not as much of issue whereas accuracy and consistency are. All rifles used in the 50-meter competition are bolt action single shot .22 LR rifles. Materials and trigger tuning will vary greatly depending on the preferences of the shooter with Walnut and synthetic stocks being common sights along with adjustable cheekpieces on the competitor’s stock.

Summer Olympics 2020

The Summer Olympic Games are a great opportunity for all participating countries to showcase their best athletes. I am glad that we live in an age and time that allows for everyone to participate in this sport – even countries that have heavier restrictions on firearms than the United States.

So if you find time this coming Summer, check out the Shooting Sports that are showcased. A couple others not mentioned in this article are the 50 Meter Prone shooting which also uses .22 rimfire rifles. There is also an extremely exciting Olympic Trapshooting competition in addition to the Olympic Rimfire sports.  Thanks again for stopping by to read The Rimfire Report.

MySQL 8.0 & PHP on RedHat, CentOS and Fedora

MySQL 8.0 & PHP on RedHat, CentOS and Fedora

https://ift.tt/2EGGjbo

As you could read in this previous post, PHP 7.4 is now completely supporting MySQL 8.0 and the new default authentication plugin.

I wanted to make a summary table providing and overview of all PHP versions and how they supported MySQL 8.0 and the different authentication plugins.

As I am a RPM based distribution user, I’m using the famous repository of remi since a lot of years, and I use it then also to install PHP 7.4.0 and 7.4.1

I created a new user to test to connect with PHP and then… I was surprised to see that I could not connect to MySQL using caching_sha2_password. Of course I tried to see if my credentials were correct using the MySQL client… and I could connect… Then I tried again my PHP script and new surprise, I could connect !?!

I could connect because the password was cached. If I run FLUSH PRIVILEGES, then the PHP script could not connect anymore.

The error was:

Trying with caching_sha2_password....
PHP Warning:  mysqli::__construct(): (HY000/1045): Access denied for
user 'fred_secure'@'mysql-dc1-2' (using password: YES)

I discussed this with my colleagues. They tried ith the same PHP version and they could not reproduce my error… but they were using Ubuntu.

What’s wrong ?

So I decided to compile from scratch PHP 7.4 on my CentOS 8 box… and… it worked as expected !

After a lot of debugging, testing many openSSL versions and compilation more than 10 times PHP… I was able to find the difference and compile a rpm based on Remi‘s spec file.

The problem was in mysqli.so.

I don’t explain yet why this is a problem, and I already reported this to my colleagues, but the difference between Ubuntu packages and my compiled from scratch version and the one installed from Remi’s repo, is the absence of value for mysqli.default_socket:

mysqli.default_socket => no value => no value

So, I’ve rebuild Remi’s package removing --with-mysql-sock=%{mysql_sock} \ and it worked !

I will now wait for feedback from the developers to understand the reason and see if this is a bug. However, if you want already to use PHP 7.4.1 and MySQL 8.0 on any RedHat based distribution, you will need to have a new php74-php-mysqlnd package.

You can download this one for el8 (RedHat, Oracle Linux and CentOS):

The package is built in way that you don’t need to update all PHP 7.4 packages, but only the mysqlnd one, like this:

rpm -Uvh php74-php-mysqlnd-7.4.1-2.el8.remi.x86_64.rpm
 Verifying…                          ################# [100%]
 Preparing…                          ################# [100%]
 Updating / installing…
    1:php74-php-mysqlnd-7.4.1-2.el8.rem################# [ 50%]
 Cleaning up / removing…
    2:php74-php-mysqlnd-7.4.1-1.el8.rem################# [100%]

I hope this can help you if you faced some authentication issue with PHP 7.4 and MySQL 8.0.

I Turned Garth Brooks’ Breakfast Bowl Into a Casserole and I Would Do It Again

I Turned Garth Brooks’ Breakfast Bowl Into a Casserole and I Would Do It Again

https://ift.tt/2ECurXE

Will It Casserole?Will It Casserole?The column where we take your delicious concepts and re-imagine them as casserole creations

Some life-changing events are preserved in perfect detail, like insects trapped in amber; some weasel their way into your consciousness so thoroughly that you’ll never again know for certain what life was like before. I couldn’t tell you where I was when I first learned about Garth’s Breakfast Bowl, but I do know that I’ve thought about it roughly once a week for what feels like my entire life.

If this is your first time reading the words “Garth’s Breakfast Bowl,” the details will either make or ruin your day, depending on your stance on carbs and pork. It’s bacon, eggs, cheese, sausage, tater tots, and tortellini layered on top of each other in a big bowl like a parfait. As legend has it, this is what best-selling solo artist of all time and Chris Gaines alter-ego Garth Brooks loves most in the world for breakfast. I am obsessed with it.

I strongly recommend taking 4 minutes and 11 seconds of your Friday afternoon to watch Trisha Yearwood and her daughter prepare The Bowl; it’s an experience you won’t soon forget. In the video, as she drops garlic and cheese tortellini into boiling water, Trisha states very matter-of-factly that “[this]”—which is to say, garlic and cheese tortellini, specifically—“is what Garth requires.” I’ve watched it dozens of times, with each viewing inspiring new questions. How did Garth Brooks come to require garlic and cheese tortellini in his Breakfast Bowls? (I have nothing but respect for this; breakfast pasta is a legitimate life choice. I’m just curious.) Whence the namesake Bowl? Why not serve the components individually? And, because I truly don’t know what’s good for me—where the hell is the gravy?

This last question, the newest and by far the most perverse, set me on a dangerous path. The only thing better than a pile of breakfast meats and carbs, I reasoned, is that same pile covered in sausage gravy. Before long, I’d schemed up a cross between my cousins’ absolutely banging sausage-and-canned biscuit casserole and the Yearwood-Brooks Ritual Breakfast Pile—but with gravy. The world does not need this; I made it anyway, and I refuse to apologize.

It should not come as a shock that Garth’s Breakfast CasserBowl is very, very good. The canned refrigerated biscuits and sausage gravy tie the disparate parts together into something like an extremely fucked up, deep-dish breakfast pie. It’s a rich, cheesy, pervasively porky carb smorgasbord—exactly what you need to survive the most brutal hangover season of the year. And, true to the spirit of the original, it’s extremely easy to put together.

Should you choose to make this affront to God, man, and everything good in this world, you will need:

  • 1 pound bacon
  • 1 pound pork breakfast sausage
  • 1/3 cup all-purpose flour
  • 3 cups whole milk
  • 1 can refrigerated biscuits
  • 10-12 ounces pre-shredded cheddar cheese (or more—no such thing as too much cheese, I say)
  • 10-12 ounces garlic and cheese tortellini, thawed if frozen (you could use another flavor, but Garth will be upset)
  • 10 eggs
  • 1 – 1 1/2 pounds frozen tater tots
  • Salt and pepper, to taste

Cook the bacon until super-crispy using your favorite method. I arranged mine on a rack set inside a foil-lined sheet pan and baked it for about 30-40 minutes at 375ºF. You absolutely will not need any extra grease here, so pour off the fat as it accumulates, reserving it for another use if desired.

Next, make the gravy. Cook the sausage over medium heat in your biggest, deepest ovenproof skillet until crisp and cooked through, about 8-10 minutes. Scoop out one big slotted spoonful and reserve it for the topping. Add the flour to the skillet and stir for a minute, then gradually stir in the milk. Simmer for five minutes until smooth and thick; season with salt and pepper to taste. Pour the gravy into a separate bowl, leaving a thin layer on the bottom of the skillet.

When the bacon and gravy are ready, it’s assembly time. Take half the canned biscuits and tear them into smallish chunks. Scatter those across the bottom of the gravy skillet.

Crumble all but a handful of the bacon over the top, then sprinkle on half the cheese. Dollop half of the gravy over that. Spread the tortellini evenly over the first layer of gravy, then pour the remaining gravy on top. Add more cheese, reserving a handful or two for the topping.

If you’d like, tear the remaining biscuits into strips and press them around sides of the skillet. (This will make for a more solid, pie-like casserole; skip it if you prefer your breakfast piles on the gooey side.) Whisk the eggs together with a splash of milk and lots of salt and pepper, then pour into the skillet. Press a piece of parchment onto the surface of the casserole and wrap tightly with foil.

Bake the covered casserole on a sheet pan for 35-40 minutes at 350ºF, then remove the parchment and foil and arrange the tater tots over the surface of the casserole. Increase heat to 425ºF. Top with the reserved cheese, bacon, and sausage, return the skillet to the sheet pan, and bake for another 15-20 minutes, until the tater tots are golden brown and the casserole is bubbling hot.

Cool for about 10 minutes if you can stand it. Serve in slices or scoops, topped with lots of hot sauce and maybe another sprinkle of cheese. Now is not the time for restraint.

Eloquent HasManyDeep Package

Eloquent HasManyDeep Package

The Laravel Eloquent HasManyDeep Package is an extended version of Laravel Eloquent’s HasManyThrough that allows relationships with unlimited intermediate models. It includes support for many-to-many and polymorphic relationships.

As an example of how this package is useful to pretend you have a setup where you want to get all comments for all posts, by users in a specific country. It might look something like this:

Country → hasMany → User → hasMany → Post → hasMany → Comment 

Granted this gets pretty complicated, but with this package, you can define the relationship like the following:

class Country extends Model { use \Staudenmeir\EloquentHasManyDeep\HasRelationships; public function comments() { return $this->hasManyDeep('App\Comment', ['App\User', 'App\Post']); } } 

Then you’ll be able to call Country::first()->comments to get all the comments which keeps the familiar Laravel syntax.

To take this a step further, Povilas Korop from Laravel Daily also created a review video covering this package:

G44: A Review of Glock’s First Rimfire Pistol as It Relates to the G19

G44: A Review of Glock’s First Rimfire Pistol as It Relates to the G19

https://ift.tt/2Z3KCqF

Would it be a single-stack .45 ACP? Maybe a commercial version of the Glock 47 Border Patrol variant? There was even buzz on forums that it would be — wait for it — an AR-style firearm. Then there were those who predicted it would be a .22 LR. My only guess is that it would be a Glock 44, but I had no idea about the caliber. My gut told me the model 44 would be next. After all, Glock is up to the G48 model. Why bypass the model 44? And so here we are, with the G44 pistol … a rimfire?

Chambered in .22 LR, the Glock 44 is billed as a gun for the entire family.

RELATED STORY

Glock 44: Manufacturer Unveils First-Ever Pistol in .22 LR

Glock G44 Details

With all the fanfare of a new product launch, Glock teased up the event with an email to its subscribers, telling them to tune in on Dec. 10. I received the same email — no doubt millions of other Glock website subscribers did too — but I also received a prior email from Glock’s marketing team. Was I interested in attending an event, they asked? A bit. The next thing I knew I was sitting front row, center stage.

In fact, it was the G44 that was announced on Dec. 10. And, to my surprise, Glock chambered it in .22 LR. Yep, Glock is now manufacturing rimfire pistols. Glock introduced the new pistols with the concept of “Adventure Awaits and the Legacy Continues.”

When I asked Dr. Gunter Gigacher, President of Glock, Inc., about the manufacturer moving from a provider of military and law enforcement pistols to producing pistols for the commercial market, he said, “It is the next step and the natural progression for the company. It has been a long road to develop and we won’t produce a product until it is completely ready.”

While the Glock 44 is very unique from a Glock perspective, it is also very much the same. It’s the same size as G19 and with other features you expect in a Glock pistol: striker-fire trigger, polymer frame, polymer magazine, and plastic sights. The G44 is super-lightweight at just 15.94 ounces unloaded. If this isn’t a 21st century “kit gun,” I don’t know what is.

Familiar Glock Design

The operating system is a simple blow-back mechanism similar to the G25 and G28 .380 Auto pistols built for foreign markets. All other Glocks, except for the G46, are short recoil-operated, locked-breech semi-automatic pistols. The power of the .22 LR is by far less than the centerfire calibers chambered by Glock. A blow-back system makes sense and all other .22 LR rimfire pistols on the market use a blow-back system. The engineering challenge is reducing the slide mass to reliably operate with .22 LR loads. Think for a minute about how many different .22 LR cartridges are available.

There are cartridges with at least 15 different bullets weights, ranging from 20 grains up to 60 grains. Let’s not forget the cartridges. Ever look at Aguila’s line of .22 LR ammo? Aguila corners the market in niche loads from subsonic 20-grain Colibri rounds to 60-grain Sniper subsonic rounds. Then include all the inexpensive plinker ammo, target and high velocity loads.

The slide is unique on the G44 since it is a combination of polymer and steel, which offers light weight and strength as well as the correct slide mass to cycle all the different types of .22 LR cartridges.

G19 Sized for Training

At the event, Glock had G19 Gen5 pistols on-hand so we could compare the the two pistols side by side. They are both 7.28 inches in length and are 5.04 inches height. The G44 is slightly less width at 1.26 inches; the G19 is 1.34 inches wide. I field-stripped the two pistols and tried to swap slides on frames and it was a no go. I later heard from William Carmichael, Manager of technical Services at Glock: “Very few of the internal components are the same between the G44 and G19. Most of the internal firing mechanism is unique to the G44 due to the 22 rimfire caliber.”

The magazine is also unique and with good cause. Since the G19 and G44 are nearly identical, so are the magazines. G44 magazines incorporate ridges on the back side of the magazine body. G19s have a smooth magazine body except for the witness holes. Those ribs offer the user a tactical feel, which immediately tells the user this is a rimfire magazine, not a centerfire magazine.

At the range we fired CCI Blazer 40-grain LRN ammo through the G44s. The magazines have a 10-round capacity, so those users in states with restrictive magazine capacity laws will exhale a sigh of relief.

Rounds Downrange

It’s hard to concentrate when you have Team Glock shooters like Shane Coley and Ashley Rhueark shooting next to you. Both of them show their mastery of the sport with a sure grip and stance. And they ran the G44s as fast as they could with little muzzle bounce due to recoil. In hand the G44 is super-lightweight. I pick it up and think G19, but the weight tells me different.

At 10 yards I was able to hit the 4.5-inch-by-3.5-inch reactive hit zone on a steel target in rapid fire. I have nowhere near the level or speed of Coley and Rhueark, but I was having fun. Steel targets — round and square shaped — were set out at 50 yards, which is well plinking range, and I was able to hit them once I was zeroed in. The trigger was typical Glock striker-fire, which is boringly consistent. And you don’t bust your thumb loading the magazine like you can with other .22 LR pistol magazines.

Glock has a new plinker, and my gut tells me this will also make a great, low-recoil training pistol. When moving up to the 9mm G19, the only thing users will noticed is increased recoil. Other than that the experience will be the same. My sample pistol is already at my dealer. All I need now is lots of inexpensive .22 ammo and few empty soda cans.
