![]() ![]() This property can be used to find points that are equidistant from two other points. The point where an angle bisector intersects the sides of an angle is equidistant from the vertices of the angle.This means that they can be used to find lines that are perpendicular to other lines. Angle bisectors are perpendicular to the sides of the angle they pass through.This property can be used to find missing angles or to simplify complex angles. Angle bisectors divide angles into two equal parts.There are several properties of angle bisectors that make them useful in mathematics: ![]() Angle bisectors are important in geometry and are used in many construction andproofs. The bisector of an angle is the perpendicular line that passes through the vertex of the angle. Properties of an Angle BisectorĪn angle bisector is a line that divides an angle into two equal parts. The angle bisector of a right triangle is the hypotenuse, and the angle bisector of an equilateral triangle is the line that bisects the angle between two sides of the triangle. The angle bisector of a triangle is a line that passes through the vertex of the triangle and divides the angle into two equal parts. The angle bisector theorem states that the perpendicular bisector of a side of a triangle also bisects the remaining angle. What is an angle bisector?Īn angle bisector is a line, ray, or segment that divides an angle into two equal parts. This theorem states that if anexternal angle bisector intersects one side of a triangle at a point that is equidistant fromthe other two sides, then it alsobisectsthe other two sides. For example, if we know the lengths of two sides of a triangle and the measure of oneangle, but not the measure of the other two angles, we can use the external anglebisector theorem to find one of the missing angles. This theorem states that if one side of a triangle is divided by an angle bisector, then the other two sides are also divided in halves.Įxternal angle bisectors can also be used to solve problems involving triangles. For example, if we know the lengths of two sides of a triangle, but not the length of the third side, we can use the angle bisector theorem to find the missing length. Internal angle bisectors are lines that intersect at the vertex of an angle, while external angle bisectors intersect at a point outside of the angle.Īngle bisectors can be used to solve problems involving triangles. There are two types of angle bisectors: internal and external. Angle bisectors are important in geometry because they help us to find angles that we cannot measure directly. The bisector of an angle is perpendicular to the sides of the angle. Angle BisectorĪn angle bisector is a line that cuts an angle in half. In this blog post, we will explore some definitions and examples related to angle bisectors. It can also be used in proofs involving similar triangles. An angle bisector can be used to construct a variety of figures, including triangles, circles, and regular polygons. The angle bisector theorem states that the perpendicular bisector of any side of a triangle also bisects the other two sides of the triangle.

Print the number of lines before and after our matchĪnd if you want to see the lines before and after your match then you can use the Uppercase -C option. We can see that now instead of getting the lines before our match now we’re getting 3 lines after our match.Ĩ. Now if we want to see a certain number of lines after our match then we can use the Uppercase -A option. Print the number of lines after our match So we have 3 lines before our match here.ħ. $ grep -w -B 3 "Johnny Depp" file.txtĪs you can see we got our match but now there’s some additional context here. So, let’s just pass in a 3 which we’ll say that we want to see 3 lines before our match. I’m doing this separate from the other options that we added in because we want to pass in an argument to this. So I’m going to go ahead and pull up the last command that we just ran and now we want to add in this Uppercase -B option. So, if we want to see a certain number of lines that come before our match then we can use the uppercase -B option. So we might want to also see a certain number of lines before and after the match to get an idea of the context of where this match was found.Īnd this is especially common if you’re searching for something in a computer program that you wrote and want to see the surrounding code of the match and there are several ways that we can do this. Now another common bit of information that you might want is some additional context of where this match is found. ![]() Print the number of lines before our match It found a lowercase version on line 3 of that file and an uppercase version on line 1 of that file.Ħ. $ grep -win "john" file.txtĪs you can see that now we’re getting some information about these matches. ![]() Now just finding those matches doesn’t give us information other than knowing our text is actually there but sometimes you want some additional information.įor example, it’s common to want to know the line number of where it found our match, and to do this we can add the -n option to our search. $ grep -wi "john" file.txtĪs you can see that now we get the lowercase version of that match and the regular case version of that match as well. So we can tell it to not be case sensitive by using the -i option. Now I also added a lower-case version of that name in that file but it’s currently not returning that because grep is case sensitive. It only returned the John Abraham.īecause we put in that we only wanted whole words. $ grep -w "John" file.txtĪs you can see that it didn’t return Johnny Depp. We only wanted to search for John and not return like Johnny depp. So now let’s say that we only wanted it to return a match if it was the whole word. The following command will search these three patterns: linux, depp and, sahu. You can search multiple patterns simultaneously. Now the second line was johnny depp but it still found within this name. $ grep "John" file.txtĪnd we can see that we got two results here where it found two lines containing john and return those entire lines. $ grep "Andrew" let’s search for john and see if that has any results. When there are no results it just jumps to the next line. So If I run that then you can see it didn’t find any results. ![]() So let’s search this file using grep to see if it contains the text, Andrew. So I am here in my terminal and in my current directory, there is a file named file.txt that has a bunch of random names and dummy data. So first of all, the most basic example is simply searching for some text within a normal file. ![]() How to search file in Linux using the grep command You must follow the syntax given below to use the grep command.
![]() Poirot is accompanying his friend, Scotland Yard Chief Inspector Japp who is being installed with great honor in an exclusive Belgian order. He had fled there when the Germans invaded Belgium early in World War I. In this episode of Agatha Christie's Hercule Poirot, the great man returns to his homeland after 20 years in England. Overall, this is one of the best episodes in the series. It's beautiful and heart-breaking in it's honesty, innocence, and sincerity. Finally, I have to mention the relationship between Poirot and Virginie Mesnard. The mystery itself is quite good with a satisfactory conclusion given the clues and events leading up to the finale. Set in a different time and a different place, everything looks stunning. The Chocolate Box is undoubtedly one of the most beautifully filmed Poirot episodes. The supporting cast is equal to the task, with Rosalie Crutchley and Anna Chancellor being the standouts for me. It's almost like watching two different actors. Going from young, slim Poirot in one scene to the older, balder Poirot we're more familiar with in the next is amazing. Suchet does what I consider his best piece of acting in the entire series. The Chocolate Box is a truly wonderful, but different, Poirot episode. Poirot relates the case to Japp (in a series of flashbacks), including the solution to the murder. He meets an old colleague and is reminded of a case he didn't solve. (***)Īfter 20 years away from Belgium, Poirot returns for a visit with Inspector Japp. And the case is really quite simple - the clues are right there in front of you, but you still won't notice them. ![]() There is no investigation in the present - Poirot had actually solved the case in the past, and we get to see how in some beautifully done flashbacks. It's also one of the very rare instances where we see Poirot involved in a subtly romantic relationship with a lady (the lovely Anna Chancellor). It offers a glimpse at the earliest parts of Poirot's career - earlier even than "The Mysterious Affair At Styles" where he had already moved to England. "The Chocolate Box" is one of the best "Poirot" episodes since "Wasp's Nest", mainly for the same reason: because it moves away from the usual formula of the series and tries something different. Poirot claims that the verdict was wrong, and proceeds to tell Japp the whole story. Meeting his assistant from the days when he was still just a rookie police officer, Poirot remembers an old case from that period - the death of an ambitious Belgian government official that was attributed to heart failure. Hercule Poirot returns to Brussels after 20 years, traveling along with Inspector Japp who is invited there to be honored for his services to Belgium. ![]() ![]() ![]()

This set includes two sets of skin stickers as well, giving you decent value for money, as well as a bunch of chances to get it perfectly aligned! And the patterned trackpads in particular are a very cool feature of this set. It offers scratch-proof protection, and its anti-slip surface means it won’t inhibit gameplay. JSAUX's Skin Stickers Set is reasonably forgiving in terms of repositioning and will allow for a second or even third pass at final positioning. It’s made from a high-quality PVC material that boasts a wrinkle and warp-free application. It's available in five different designs, including the "Retro Boy" Gameboy-inspired design pictured here. The JSAUX Skin Stickers Set for Steam Deck offers a custom sticker pack for Valve’s handheld marvel, which includes a vinyl skin decal sticker, an anti-slip grip sticker, trackpad stickers, plus a set of thumb grip caps. And should the day come when you want to take off your skin (so to speak), it allows for fast and clean removal, leaving no residue behind. It offers UV, dirt, and scratch protection for your Steam Deck, and offers a solid gaming grip as well, once applied. Reassuring, given the cost of this skin, that it’s not a "one-shot" vinyl sticker.Īs a bonus, this premium skin is made using eco-friendly inks too. Cleverly, the "sticky side" is coated in pressure-activated adhesive meaning it can be guided into place, and even repositioned before being stuck down. Made from high-quality vinyl, this skin is cut with an air-release channel that allows for fast, bubble-free installation. This means, aside from the screen (obviously), it masks every square inch of the Steam Deck, leaving it looking resplendent with a cool arctic white covering that includes the D-Pad, triggers, and trackpads. Precision cut for the Steam Deck, the POP SKIN Steam Deck Skin is a full covering skin for the handheld console. These are the best alternative skins for Steam Deck available right now. These precision-cut skins come in a variety of styles and designs and offer scratch-resistant protection, as well as some visual flair. If you own a Steam Deck or are thinking of buying one soon, you may wish to consider investing in a vinyl skin set to bring some color to your console. Valve's Steam Deck is arguably the most sought-after handheld game console on the market right now, and gamers lucky enough to own one are already enjoying the benefit of playing their favorite titles on the go.

Now I know what you’re thinking – How does this taste?! Well… Let’s just say Mr. This dreamy peanut butter tres leches cake melts in your mouth and is all the more delicious thanks to the creamy Skippy peanut butter in the cake and frosting. This recipe really comes together pretty quickly. Beat 1 cup cream and 2 Tbs powdered sugar in small bowl at medium-high speed until stiff peaks form. This recipe seems kind of long, but I’m just being thorough. Remove top, spread bottom layer with strawberry preserves. When you’re ready to serve, just remove the springform portion and leave the cake in the dish. Increase the speed to high and add the ¼ cup of sugar in a stream. Add the egg whites to the bowl and whisk the egg whites, over medium/high speed until it forms soft peaks, about 2-3 minutes. Clean and dry the whisk attachment and mixer bowl. You’re going to need the platter, because spring form pans don’t hold liquid puddles. Transfer the egg yolk mixture to a large mixing bowl and set aside. To keep the cake from toppling I placed it in a springform pan with a rimmed platter underneath. I went sort of naked here, as tres leche cakes won’t dry out. Then it’s just soak the cakes and fill as you would any other cake. Cakes are baked and poked, soaking liquid is mixed, and whipped cream topping is whipped.

Thankfully Fine Cooking has a very sturdy recipe which uses egg yolks folded egg whites and no butter. If you want to make this stacked action happen – You’ll need a very sturdy cake to pull this situation off. Usually tres leche cakes aren’t stacked because soaking a cake in a milk mixture makes that jammy pretty heavy.

It’s a sturdy cake soaked in three milks – Evaporated milk, sweetened condensed milk, and heavy cream. This year he asked for two cakes – And seriously – How could I say no?

But those same neighbors should also appreciate the fact that you’re using a silent tool and not a squealing string trimmer. There’s no question you’ll look out of place and people might whisper when you’re not looking, but that’s okay because your eye-rolling neighbors probably don’t understand what an enjoyable, peaceful time you’re having. Cutting grass with a scythe has a learning curve, and knowing how to sharpen the blade is essential, but these are both learnable skills and not as physically demanding as you may think. In a lot of ways, it’s the anti-string trimmer. ![]() In addition to its cutting abilities, it offers a tranquil mental and physical experience, accompanied only by the whooshing swish of the blade against the grass. The scythe is an ancient tool, discarded by our modern culture, yet wildly effective at cutting grass. If your trimming needs include taking down a large grassy area, like an LA hillside or maybe a spot that’s not quite lawn, but also not quite woods, consider bringing a scythe into your life, specifically, the Lee Valley Traditional Austrian Scythe Set. This model replaces our previous top pick, the Ego ST1521S, which is almost identical except that it lacks the telescoping shaft and the easy handle adjustment. It wasn’t the lightest trimmer we tried, but its excellent balance and handle adjustments made it one of the simplest to swing around and maneuver in tight spots. There are a variety of systems that do this, but the Ego’s is the easiest we’ve tested. The Ego comes with a push-button line-load system, which eliminates the typically tedious process of putting a new line on the spool head. It was also among the most capable cordless trimmers we found, with enough run time to cut a 1-foot-wide strip of grass almost two-thirds of a mile long on a single battery charge. The Ego ST1511T is just as powerful and affordable as a gas tool-but without the messy fuel, smelly exhaust, or time-consuming maintenance. ![]() This allows it to work for a wide variety of heights and body types. This model, the latest in a long line of successful Ego trimmers, distinguishes itself with an easily adjustable telescoping shaft and a quick adjustment for the secondary handle. But it was the quietest tool we tested, with a hair-dryer-like hum that sounded more pleasant than the whine of its competitors. Considering all that power, you’d expect this trimmer to be noisy. This trimmer cut through 1-inch-thick Japanese knotweed as if it were grass, while most of the others pathetically slapped their strings against the thick stalks. Compared with other cordless trimmers, the Ego ST1511T Power+ String Trimmer with Powerload is on a different level. ![]() ![]() ![]() Second, if you are you want to graph data over UART, it has a really nice and easy-to-configure setup. First is that you can skip many of those instructions for other tools, especially in Mac and Linux systems. I personally came across Serial Studio recently and found it to be awesome for two main reasons. Some recommendations include:Īpart from Serial Studio, some detailed instructions for the different operating systems are available in the Discovery Book.įor me, Serial Studio comes highly recommended. In addition to the above, you would need to install some sort of serial communication terminal on your host PC. ![]() Note that if the code on the git repo is slightly different then it means that it was modified to enhance the code quality or accommodate any HAL/Rust updates. To understand the content of this post, you need the following:įamiliarity with the basic template for creating embedded applications in Rust.įamiliarity with I2C communication basics.įamiliarity with UART communication basics.Īll the code presented in this post in addition to instructions for the environment and toolchain setup are available on the apollolabsdev Nucleo-F401RE git repo. I probably will be expanding the code anyway to create a BMP180 device driver at a later time. However, the provided code can be easily expanded to collect and convert pressure data as well. My target in this blog post is to focus on operating I2C more than the features of the BMP180 itself. I elected to collect only temperature data since the conversion equations are less. The BMP180 provides both temperature and pressure sensor data which are collected in a very similar manner. This means that I will be leveraging only the embassy HAL without the executor or the async framework. This code will be built without using any interrupts. Temperature measurements will be continuously collected and sent to a PC terminal over UART. ![]() Note that the BMP180 provides both pressure and temperature data but I will only be collecting the latter. In this post, I will be configuring an STM32 I2C peripheral using the embassy HAL to collect ambient temperature measurement data from the BMP180 Digital Pressure Sensor. Please be aware that certain concepts in newer posts could depend on concepts in prior posts. This post is going to explore communicating over I2C using the embassy HAL. This blog post is the fourth of a multi-part series of posts about Rust embassy for the STM32. ![]() |
