![]() So, even though we preemptively deleted all the related data from users_roles, Postgres still must check at the moment of the delete if that is still true. If even just one record depends on that value, the foreign key constraint is going to flag that and abort the delete action. If the foreign key value isn't being used by any records in the associated table(s), then the delete can proceed. How is the foreign key constraint having such an impact on performance?įor every single row you tell Postgres to delete from the roles table, it is going to first check with all dependent tables to make sure it is okay to do that. Because of this assurance, I never have to worry that data is going to be inadvertently orphaned. ![]() They help ensure that the data relationships between two tables are always intact (that's called referential integrity). This isn't the solution.įoreign key constraints are essential to solid schema design, and they are one of my favorite features of Postgres. This was to highlight the impact of the constraint.

The full queries are embedded in these code blocks, but you can also check out the code in this repo. If that interests you, let me know and I'll write a follow up. The specific of how this works are out of scope for this post. Here is some SQL that will generate our schema for reproducing the performance issue. Another record in this table tying my user record to a team_collaborator role for the Red team would tell you that in addition to being an admin, I am a collaborator of the Red team. ![]() A record in this table tying my user record to the admin role would tell the system that I am an admin. Then we have the roles table which can contain global roles like admin and support as well as roles tied to specific resources like team_owner and team_collaborator.Ĭreating a relationship between the two is the users_roles join table. It doesn't feature strongly in the example so I'll leave it at the id column. If you want to skip over the example setup, you can jump right to the details.įirst is the users table. These roles help the system determine the access and permissions of each user. Most software systems have users and those users need to be given a variety of roles. ![]() This minimal example is also a real-world example. Without that index, we're bound to run into some really sneaky performance gotchas. I don't tend to think of foreign key constraints as impacting performance. We can combine the two to start getting the most out of our database. Much better! Toward the end of the post we'll see how to make it even faster than that.īut before I reconstruct a minimal example that reproduces the problem and get into the details, here is the.įoreign keys are essential for enforcing the shape and integrity of our data. 10,000x slower! □ That's a nope.Īfter diagnosing and addressing the issue, I got that second delete query down to about 1 second. I then had a similar query deleting the same number of records from another table that would run for ~30 minutes. I had a query deleting 50k records on one table in ~100ms. Let me give you an idea of how bad it was. And I'm paying the lesson forward with this article. I'm better equipped to diagnose the next performance skirmish that comes my way.

Finally there was the blue tracking problem. Ground and aviation units from other Services and nations participated. In Fallujah the additional challenge of a counterinsurgency environment existed, thus the need to minimize collateral damage and win hearts and minds, something not achievable if a city is razed by aerial attacks under the glare of a ubiquitous media.Īlso, it was a joint fight, both on the ground and in the air. Any type of urban CAS qualifies as one of the most complex and demanding tasks known to modern warfare. It had been substantially facilitated by CAS. The high-tempo penetrating attack envisioned by Marine commanders was realized. I never knew a time in November when I had a TIC when I didn’t get an airplane within about a minute”.Īlthough sporadic fighting continued for weeks after, it took about 10 days for the main resistance to be squelched in Fallujah. “I tell you what, for like three weeks, it felt like nothing but a continuous faucet, a continuous fire hose of airplanes. Air strikes came continuously and in harmony with other fires most were “danger-close” and rapidly sequenced. In the follow-on battle, as the Marines, soldiers, and coalition troops fought door to door throughout the city, supporting fires were perpetual, a cacophony of precisely delivered destruction. The bombs created breaching lanes for Marines of the 3d Battalion, 1st Marines to exploit later that day. The main assault into Fallujah in November 2004 ( Operation PHANTOM FURY/AL FAJR) commenced when eight GBU–31s, 2,000-pound joint direct attack munitions (JDAMs), dropped by Marine Fighter/Attack (All-Weather) Squadron 242 F/A–18Ds, smashed into a railroad-topped berm bordering Fallujah’s north side. This maximized the fantastic capability of aviation precision weapons and targeting technology, and in the case of Fallujah, made fixed-wing CAS an appropriate option for supporting fires, underscoring the utility and need for tactical aviation (TacAir) in the Marine Corps. The CAS plan was built on Marine Corps C2 basics-procedural control and unity of command, which were enhanced with a common map or grid reference graphic (GRG). Urban close air support ( CAS) successfully employed in Fallujah in 2004 highlights the capability of Marine Corps-style command and control (C2) of aviation. *** Operation Phantom Fury (Second Battle of Fallujah): Operation Phantom Fury was a joint U.S.-Iraqi offensive in November and December 2004 (Credit: USMC) He earned his doctorate in history from Texas Tech University and is currently a historian at the Marine Corps History Division, Quantico.

However, some of these choices are also unequivocally horrible. Will it give me the villain tag if I continue doing so (Im not talkign about taking their source during a dialogue). Some choices on this list are not that dangerous and probably won't spoil the player experience too much. Tags referring to Origin, Starter or Gender types are defined at the start of the game and cant be changed anymore. Race, occupation and fame are some key tags that may affect interactions with others, opening as many doors as they can close.

There's only one global way to get the Villain tag, per the script, and that's to murder three innocents with or without Source Vampirism. Moreover, there is little foreshadowing as to those consequences, as well. A lot of the things people say add the Villain tag don't. Playing Co-Op with 3 friends, we got the Villain tag due to one of us hijacking all the dialogue choices and choosing the cruelest options. ![]() The game doesn't tell players what the consequences of their actions might be.

The Yahboom G1 Smart Tank is an excellent choice, even for a first robot kit. You can find all the details on the manufacturer’s product page. The price is correct (around $100), and I keep thinking this is one of the best alternatives for a first robot kit to go further with your Raspberry Pi. The MagPi made a review recently, they count over 128 components to assemble! It seems a bit too much for me, as I’m looking more for the coding part than the Lego part, but it could be fun to do if you have time.īy the way, this process is very well documented with video and pictures, so it shouldn’t be an issue for most of you. The main problem with this robot is probably the assembly part, it’s one of the robots with the most components in the pack, this picture scares me a little: Also requires 2 batteries 3.7V (as for the previous robot, I recommend a pack with a charger, like this one on Amazon).Use its ultrasonic sensor to avoid obstacles.You’ll get several examples in the documentation. You can code it with Python and DragIt (that I don’t know, but that seems close to Scratch). It’s compatible with almost any Raspberry Pi model (except version 1). If you are lost in all these new words and abbreviations, request my free Raspberry Pi glossary here (PDF format)!Īside from the cool design, the PiCar-S is also a good competitor if you need a robot kit. The learning curve is very progressive as you can start to play with the app, then the computer app, and finally try to code it yourself with Python (many tutorials and examples are included) The assembly is pretty fast compared to some other alternatives. It’s probably one of the best choices for beginners. The FreeNove 4WD Smart Car is an interesting one, I saw a video and was impressed by the possibilities (I’ll show you the video just after). You can also find it on Amazon if you prefer. Don’t worry if your obstacle avoidance script doesn’t work the first time.Ĭheck the price on the SunFounder website, and get yours now if you are looking for a fun project with your Raspberry Pi. The price is slightly higher than the average of the kits you’ll see in this list, but the material they used is way better, so it should last longer. I explain everything in my full review, so make sure to read it if you are interested. It comes with specific software (EzBlock Studio), allowing you to use a visual language (EzBlock) to play with it or jump to Python for more advanced scripts. Then, you can control it from your phone, your computer, or directly from the Raspberry Pi. The package is well organized Great instructions for the assembly EzBlock in action Includes tons of examples with EzBlock and Python There is a big assembly guide in color, explaining all the steps and all the screws and various pieces are labelled, so it’s easy to follow. Aside from the servos (that you’ll get with any kit) there is nothing complicated, so it’s great for a first kit. The assembly is pretty easy ( I have a complete review here). A grayscale module: to use for line tracking or cliff detection.An ultrasonic module: that measure the distance between the front of the car and the next obstacle, so you can program obstacle avoidance. ![]() A camera module: you can use it for face or sign detection, for example. ![]() The PiCar-X is compatible with a Raspberry Pi 2B, 3B or 3B+ and 4B. It can be controlled from your phone or your computer and programmed via Python or EZBlock (a visual language like Scratch). The PiCar-X from SunFounder is a robot kit, a car powered by a Raspberry Pi and loaded with various sensors. ![]() The first third of the book teaches you the basics, but the following chapters include projects you can try on your own.

There is no rational order in this list, as it’s almost impossible to give them a fair score, but the ones I prefer are at the beginning. In this list, I share my discoveries and give you my advice on each of them. I’m very interested in robotics right now, and I have tried several kits for you. And at the end of this list, I will give you the one I prefer. ![]() I will try to give you a clear overview here about each kit, so you can make your choice, or just dream of buying one someday. So, which is the best robot kit for Raspberry Pi in 2023?Įach robot kit has its different features and depending on your need, your budget and your skills, it can be overwhelming to find the good one for you. In the few last years, many robot kits have been released to allow anyone to try them, either to play, to learn programming or for more complex challenges. Robotics is a trending topic right now in the Raspberry Pi world, and it’s not always easy to find the product we need. |
