Hello everyone, welcome to the next lecture in the course remote sensing principles and applications. In this lecture we are going to see few properties concerning electromagnetic radiation. In the last class we have seen the basic laws which helps us to calculate the amount of radiation emitted by natural objects. So we know how electromagnetic radiation is produced in nature, the basic principles of it. Now we are going to study what are the basic properties of this EMR and how these properties will be helpful for us in remote sensing purposes. The first property of EMR that we are going to study is known as the polarization. When I introduced you to electromagnetic radiation, we came to know that EMR consists of two components electric field and magnetic field. We also studied these fields, two fields will be perpendicular to each other and also to the direction of motion. But even if we consider these two components are perpendicular to each other, in a three dimension space they can take any orientation. They can be vertical like electric field can be vertical can be horizontal or can be continuously changing its orientation and so on. So polarization indicates the orientation of the electric field in electromagnetic radiation. So in which direction electric field is oriented in relation to magnetic field and also in relation to direction of motion. So this is polarization. So the sunlight that which is the primary source of energy for remote sensing purposes consist of waves at different wavelengths and with different polarizations that is it is a mixture of waves which consist of different different wavelengths and different different polarizations. So we naturally call the sunlight as randomly polarized or some literature call it as unpolarized that is it contains waves with variation in polarization. So some of the common polarization or we call it as like horizontal vertical circular and so on. So first we see what a polarization is by two examples then we will see more about few intricate details about polarization. So in these two figures we have examples for two kinds of polarization. The figure 1 like I label this as figure 1, this is figure 2. In figure 1 the red line is the electric field, blue line is the magnetic field. If we observe the wave is progressing from left to right in the screen and the electric field is vibrating in a plane perpendicular direction of motion and if we look at it we can see that the electric field is vibrating in a vertical plane that is say if we take this direction as x, this direction as y and this direction as z then the wave is progressing in x direction along the x direction, electric field is vibrating along the y direction and magnetic field is vibrating along the z direction. This remains constant throughout the wave progression. Look at figure 2 using the same coordinate axis system, the wave is still progressing in the x direction, here electric field and magnetic field are vibrating in the y z plane that is perpendicular to the x direction that is okay but the orientation within the y z plane keeps on varying it is not a constant as the wave progresses the orientation of electric and magnetic fields keep on varying that is if an observer is standing here and viewing the say this is like eye of an observer, if the observer is standing here looking at the wave coming towards the observer he or she can sense that the wave is now rotating like the orientation is continuously rotating when it is coming towards the observer. So the electric and magnetic fields are vibrating in y z plane only but the orientation is not constant it is keep on changing while coming towards the observer and the observer can sense it is almost like a circle like it is rotating in form of a circle. So this is this kind of in figure 1 the polarization in which electric field is vibrating in only one particular plane we call it as plane polarized wave that is the wave is vibrating or the electric field is oriented in only one particular plane we call it as plane polarized wave whereas in figure 2 we call this as a circularly polarized wave or circular polarization whatever circularly polarized wave. So essentially if the orientation remains in only one plane we call it as plane polarized if the orientation keeps on changing as the wave progresses we call it like either if it is circle we call it as circularly polarized if it is elliptical we call it as elliptical polarized there are different names. So how to relate this polarization with respect to the plane of incidence that is let us assume there is a plane or surface here electromagnetic radiation is coming towards it and going to follow it. See this is the plane of incidence let us assume this is a plane polarized wave if this particular incoming wave has its electric field oriented along this direction that is it is vibrating. See if you take this as x if this as y if the electric field is continuously orienting itself only in the y plane then this is like a plane polarized wave and this direction of orientation of electric field is parallel to the plane of incidence the plane of incidence is like this horizontal and the electric field is also vibrating parallel to it such orientation in which the orientation of electric field is vibrating in a plane parallel to the plane of incidence we call it horizontal polarization. On the other hand if the surface is like this this is the incoming wave in the incoming wave the electric field is if it is like vibrating in this particular direction that is perpendicular to the plane of incidence then we call that particular polarization as vertical polarization. So if the plane of vibration is parallel to plane of incidence that is horizontal polarization if the plane of vibration is perpendicular to the plane of incidence that is vertical polarization and these two kind of polarization in which the electric field will be vibrating in only in one particular wave such waves we call it as a plane polarized waves. So some of the common polarizations we use are horizontal, vertical, circular, elliptical and so on. So this is the basic orientation of electric field which defines with which polarization electromagnetic radiation is coming in. What is the need for studying polarization? Why do why we should care about in which direction the electric field is oriented is not it necessary if we just look at the total amount of radiation coming in actually the total amount of energy coming in or reflecting out of an object will vary with polarization also that is I will give you like an example. So in this particular figure same area is photographed at a same time but which two cameras one attached with a horizontally polarized filter and one attached with a vertically polarized filter okay. So one on the left is a photograph taken with the filter allows only vertically polarized light and on the right the filter will allow only horizontally polarized light. So you can see the picture is for the same region taken the same time but these two pictures appear completely different because as we have studied that the coming incoming energy or the reflected energy whatever may be will have spectral variation that we know that is the energy will vary with wavelength and also within a given wavelength the amount of energy will vary with polarization also that is say whatever energy coming in from the sun a certain fraction of energy will be waves will be having certain position some may be horizontal some may be vertical some may be like circularly polarized and so on. Similarly when electromagnetic radiation is incident of an object and interacts with the object naturally the polarization will change like some objects will reflect more of vertically polarized light some objects will reflect more of horizontally polarized light and so on. So essentially the amount of energy that is incident on an object and reflected on an object will vary with respect to polarization also. So the sensor which we use should be able to capture this polarization effect that is by looking at the polarization also we will be able to understand more details about the object ok this object is reflecting more of horizontally polarized light this object is reflecting more of vertically polarized light. So such polarization information will help us to know more about the object and limiting one particular polarization will actually limit the total amount of energy coming in that is like in this photograph itself shown in the slide the one on the left actually removed all the horizontally polarized light. So from the total amount of radiation coming in towards the camera a certain amount of energy is removed only vertically polarized light is allowed in whereas on the right side only horizontally polarized light is allowed vertically polarized light is totally removed. So if you look at this photographs in inferred the one with vertically polarized light appears much brighter the one with horizontally polarized light appears much darker. So what it means in this particular scenario in the in we look at the total amount of energy coming in the energy had relatively a larger component of light that is vertically polarized rather than horizontally polarized light. So by limiting the waves in certain polarization we will be limiting the total amount of energy reaching an object that is a major implication and also as the objects interact with EMR the orientation of electric field that is the polarization tends to change which gives us an indication about the nature of the object. Normally like when we go out in bright sunny days we used to wear polarizing sunglasses if we wear such polarizing sunglasses our eye the outer surfaces will not appear so bright we will feel comfortable. Why because the polarizing sunglasses naturally filters out certain polarization out like some of the polarization will be removed that means you are limiting the total amount of energy reaching our eyes that is why our eyes appear comfortable when we wear a polarizing sunglass. So polarization having certain polarization filters will help us to limit the total amount of energy coming into a sensor. Similarly based on polarization we will be able to know more about the objects that is reflecting it and this is really important when we do microwave remote sensing in microwave remote sensing the sensors will be capable of observing microwave signals in different different polarizations like horizontally polarized, vertically polarized, cross polarized and so on and each object will behave differently under different polarized polarize signals. So polarization is really critical in order to understand about the nature of objects. The next property we are going to see about electromagnetic radiation is known as coherency. Before looking at what coherency is let us quickly go back to our school physics days and recall what is known as a phase of a wave. So we will see what is a phase of a wave. So this is like one full cycle of a wave let us say a time is taken between like 0 and at certain interval time t and at a certain distance d that is lambda it completes one full cycle. So for this one full cycle of wave at each stage we will be able to tell we should be able to tell at which stage the wave is that is if I tell you this is like total time t0 ok. If I say what is the stage of the wave at time t1, what is the stage of the wave at time t2, what is the stage of the wave at time t3. If I want to tell at which stage the wave is progressing at a given time interval at which stage of wave is progressing we can we have assigned certain angular values to it safe example if the wave is just going to start from its 0th state we call it as phase 0. Let us say after time period of t1 the wave has come to its peak in its positive side we call it as phase pi by 2. Then after crossing the peak in positive side it comes towards the 0 again we call it phase 5 then it goes in the negative direction reaches a negative maxima we call it phase 3 pi by 2 then again it comes back to 0 we call it phase 2 pi then we say the wave has completed one full cycle. So, just for our convenience we say ok the wave is when the wave is progressing at which stage the wave is whether it is like in phase 0 phase pi by 2 phase pi phase 3 by by 2 and so on. So, so the phase is essentially will tell us at a given time or at a given point in space what is the stage at which the wave has progressed this is like a simple explanation for phase we generally correspond angular values to it and also commonly we call it as phase angle or phase and so on. So, two waves are said to be coherent when they have a systematic phase relationship between them what is meant by a systematic phase relationship say two waves a and b are travelling together. If these two waves have same phase at a given time t or at a given space x y whatever phase can be calculated both a temporal scale and spatial scales. So, if the phase is constant if they have the both the same phase or if they have a same phase difference then those two waves are said to be coherent. So, we will see this with few examples there is two waves given here one with like a blue color marked with blue color one marked with a red color. So, here what what is happening is say this is like the time axis. So, these two waves like the wave is starting here say I just extrapolated and this wave is starting here say at a given same time interval say at this particular time interval t 1 the wave marked in blue is just starting here whereas the wave marked in red is as started from a 0 value and is moving towards this peak. So, when wave 2 the wave marked in red color reaches its peak wave 1 is still not reached its peak value. So, this denotes wave 1 and wave 2. So, I call this as wave 1 I call this as wave 2 wave 1 and wave 2 has a phase difference among them. These two waves do not have the same phase they have phase difference among them. So, if they have a common phase difference if the phase difference remains constant throughout whenever it is along in the time axis say the phase difference is constant throughout as it moves the time axis then we call this wave as coherent that is the phase difference is there but still the phase difference is constant throughout. We look at the example given in the bottom figure two waves are there same blue wave and red wave but here in this case both the waves are exactly in the same phase at the same time interval that is when it is time 0 both the waves are starting when the time is 2 seconds it is like 2 units both the waves are reached its peak in its positive side when time is 4 both the waves are reached 0 again. So, essentially it means both the waves are exactly in phase then also we call these two particular waves as coherent. So, as long as two waves have same phase or constant phase difference we call those waves as coherent waves on the other hand if the phase difference varies either with respect to time or with respect to space then those two waves will not be coherent. So, those two waves should definitely maintain a systematic phase relationship they should either be have been same phase or have a constant phase difference then only we call those two waves are coherent waves. So, we go back to the previous slide yes two waves will be perfectly coherent only if they are monochromatic and they are parallel to each other. So, what exactly monochromatic is? Let us say two example of two waves a b. So, wave a is like this slightly longer wavelength wave b is like this. So, this is some time t naught in time t naught wave a completes only one cycle whereas in the same time t naught wave b completes 3 cycles which essentially means at any given time interval at any given time interval say t 1 t 2 1 doll if you calculate the phase between these two waves the phase will not match there will be a phase difference and this phase difference will not be constant the phase difference will be keep on varying as the time progresses because of this difference in wavelength and or frequency of these two waves the phase difference also will be keep varying. So, unless these waves are monochromatic that is they travel with same wavelength or frequency they cannot be perfectly coherent this is one thing and second thing is the wavelength should be collimated. So, what exactly collimated is they should travel parallel to each other or they should be having same path length. Let us say this is point a this is point b. So, one wave like two waves are actually starting from point a with a wavelength lambda and one wave is traveling directly to point b another wave is traveling in a different direction there is a mirror kept here at point c another wave first travels towards c gets reflected at c and then reaches a let us assume. So, even though the net displacement of the wave is from a to b because of the difference in length traveled and the distance difference in the time taken to reach a to b these two waves even if they were coherent at the initial starting point due to the variation in due to the variation in the path length and the time interval t they would have definitely become out of phase their phase difference or the phase relationship between them would have changed. So, two waves will be perfectly coherent only if they are parallel that is they are traveling parallel to each other and only if they are monochromatic. So, what is the implication of waves being coherent or not? So, the main another example is given in this particular slide in this particular slide we have seen these two waves are in phase they are coherent. So, at a given time interval they are having exactly same like they are having certain phase certain amplitude like this peak or this stuff we call it as amplitude how much it is varying from the central 0 axis 0 plane of vibration. So, when two waves are exactly in phase the amplitudes will add up and will produce a net resultant wave with an increased amplitude like these two amplitudes will add up say if this is 2 unit if this is 2 unit when they add up they become 4 unit. Similarly, on the negative side also this is minus 2 this is minus 2 this becomes minus 4. So, when two coherent waves meet up they produce what is known as interference that is their amplitude changes because of the mixing of or the interference of these two waves. So, if two waves are in phase with each other the amplitudes will add up and it will produce a net resultant wave with a much larger amplitude variation. On the other hand, if two waves are coherent, but they are not in phase like here wave 1 and wave 2 they are coherent actually they have a constant phase difference between them like it is the phase difference here it is pi by 2 on the positive side here it is 3 pi by 2 phase. So, the phase difference is more or less constant here when it reaches 3 pi by 2 here it is pi by 2. So, the phase difference is constant. So, these two waves are coherent, but when they mix together with each other because of the exact opposite sign in amplitude they get nullified and produce a wave with 0 amplitude. That is when two coherent waves meet they either increase the amplitude of the net resultant wave or they decrease the amplitude of the net resultant wave this is what we call it as interference. So, coherence sometimes it will be like positive to us sometimes it will be negative like if you look remote sensing images due to coherence there can be some bright patches all along the image which will like obscure our signals it is essentially it will occur more in microwave remote sensing the coherence is quite a lot. So, coherence or interference will kind of act as a minor disturbance for us in remote sensing images. So, this is one of the important property about EMR that we should keep in mind coherent radiation produce interference the interference can be positive interference that is the amplitudes can add up if two waves are in phase or the interference can be negative that is those two waves can cancel out each other if they are out of phase. But non-coherent waves cannot produce interference like if the waves are not coherent interference problem will not be there. So, just to summarize what we have learnt in today's class we have studied two important properties of EMR one is polarization another thing is coherence. So, polarization will help us to know what is the amount of that is will help us to understand what much of energy is coming in with different polarization and also how the objects interact and second we have seen what coherence is and how coherent radiation will either increase the amplitude of the net resultant wave or decrease the amplitude of net resultant wave. So, with this we stop this particular lecture. Thank you very much.

Mae ydych chi'n gweithio'n gweithio'n gweithio, I don't know whether that's going to help. Well, completely straight. One of the problems that we have with Iwami is that first impressions are incredibly important. And we know that people is like an incredibly good piece of software, but it doesn't always come across that way when somebody first installs it, someone gets hold of Drupal and installs standard or minimal. The initial impression that they get is not necessarily as good as the software that underpins it. This is what Drupal looks like after installing standard. Who thinks this is awesome? Without any sense of irony or misplaced loyalty, this is awesome. Isn't that different to how like Drupal 6 was? I'm not sure about Drupal 5, but in fact he filled in a whole lot of posts on going back and trying to install Drupal as far back as he could. This is kind of not that different to like 2 or something. So it's not a very good first impression of Drupal and the capabilities of it. So what is Iwami? How will we try to address this concern? Iwami's had installation profiles. Is everyone happy with installation profiles? No. Okay. So installation profiles are a way of installing Drupal with some prepared configuration and sometimes some code and a set of modules that you've chosen to gear it towards a specific purpose. If you've ever installed Drupal, you will have seen some installation profiles. You get a choice between minimal and standard when you install Drupal. Those are the two installation profiles that come with Core 5.0. So what we're doing here is giving a stirred installation profile with Core that is better placed to showcase the capabilities of this piece of software. Okay? That's why we call it out of the box. It's to demonstrate what you can do with Drupal without any contribution modules, just what you can do with Drupal 8.0. And with Drupal 8 you can do so much more than you could with Drupal 7 without having to resort to that fact of contributing modules. Who is this time to that? Your Mami installation profile is a demo and it describes Drupal for evaluators, people who are looking at Drupal saying, is this the right fit for our organisation? Can this do what we want it to do? What does it look like? Also technical evaluators can take a look at it and see how you do things behind it and see what is an example of an implementer site actually going right. It's also useful for developers and site developers if you want to have a look at the new feature in Drupal and how to develop what configuration you need to make it fly and what changes you can do, you'll find that they're actually adopting lots of new things into this as they get added into the core. And it also lets us evaluate different Drupal features as well. So how did we actually get here? This has been a very long journey that's had on a lot of people. This is not nearly everyone that's been involved in it, but Llorie Asgolett has been a driver of this for a long time. Just to the two of us, there's done a hell of a lot of work with this. KeyJ has done a lot of work on the design. As you can see with KeyJ, we have Sharon J over here. We'll see a lot of recipes. Sharon has made all these recipes. She's invented them so that we don't have to worry about the copyright recipes and so that Key can focus around them to include them in the demo. So a lot of work on in there. We actually went and assisted that Sharon J created through Drupal.org and counted so that she could get a commit credit for all the work she did cooking. I'm not going to read more than that. Mark, I've always been really important driving this forward. Llorie, Llorie, I'll publish these slides so you can have a load. There's a lot of different roles. Obviously, we went here really important in actually giving us a bite, giving us the roots in suit, the powers that would be so that we can actually get this thing in. Roy Sholton, very important from the UX point of view. We're building something that's the 80s or experience, so we need a guide who is very similar to the UX within Drupal circles to guide us and give us inspiration there. Gabor Hotski, Lee Rowlands, Llorala, have been really good at being committed so when we get so ready to go, they guide you around to say, can we put this in yet, and actually get it committed. Terry Fish has been really good at helping us with the light issues and Henry McPherson has been really good with a lot of the accessibility work we've got. So, lots of people. This has been gestulating in some form or another for ten years. If you actually looked at the initial issue that kicks us off, the concept about it is some sample content at the core. It's actually got a five-digit node number, 79582. So, that's the only five-digit issue that I want to ever get to know about, I'm pretty sure. So, it's been going on for a long time, and then a couple of years ago in... Is there a couple of years ago that used to go by? It feels so much longer. A lot of momentum was gathered there. A lot of people got together after a couple of sessions there. And going forward, we've been doing weekly newsings that we have a Slack channel, and we talk about this, and they have a program and the sample content merged together into one initiative to develop something that looks Slack, something that's well-configured and has some nice contents that people can actually play with people at the box. It was originally... There was this farmers market idea around default content. That was going to be the model, but we moved to our kind of food magazine and saved us from the best. A bit better place to showcase the features of people that we wanted to include. Everyone's still keeping up. Everyone's still going. So, what do we want to do with this now? We wanted to improve the understanding of people's core flexibility and capability to evaluators by providing an on-boarding experience. This is something you can put in front of anyone that can start playing great and make changes to it and see what happens in a way that they can't really do in relation to front bars. It's a much better way to demo if you're trying to show off briefly, if you're trying to say this is good, it's a much better way to spin on that and show what you can do about adding any extra code to it whatsoever. It's a scenario that's suitable for growing with people. We've seen if we have this experimental process where we can add contents and if they become stable in core we can add these features to it and we can do that and then showcase them and see what they can actually do. It improves the perception of Drupal's capabilities. People will not just install Drupal and go, oh, it's like WordPress that I'm hard to use. So, it took a lot of time to plan this. I say, really, I still wasn't involved at this point. But actually, I advertised a goal for the designer, and that was Keith Jay for five months. He was leaving the design world and other designers were involved. And then there was a long period of just doing a design process, getting it to look like it was looking. Before developing a more formal style of knife and then actually implementation in anger going on September 2017. And then in February 2018, just last month, we got it into Drupal 8.5. So, when you get Drupal 8.5, you want to release it to the cheese house boom, this month, right? It will have the money in it. If you go and play with the release time of it and download it, you can actually install the money down there and see what we've been doing. So, this is now actually particle. So, people don't believe me. It is. I don't want to prove it. So, the design process. So, we started doing this like a proper project. We used stories looking at different evaluation roles that we've identified. We built a concept model for the MVP. So, we have a couple of concept types. Articles about food recipes and the fields involved with them. Images, difficulties, tagging, that kind of thing, that kind of thing. We framed it against the concept model. You can see that there was a community review under this. No number. We're well out of the five video ones now. And this is what the front page came up with. But this is the output of the design process. So, you can see we've got some very cool Drupal stuff here, like content types and views, blocks and menus and items and so on and so forth. Most of the stuff we've done is demonstrate with Drupal. And it's at this point that we can definitely solidify on this idea of having it being there. So, this is Imami as a brand. The magazine style really helps give us a lot of reading space. It allows us to have a light touch of the thing that we can play with while exploring the customization later and doing more with it and then promoting it. Very, very cluttered. And the concept types are really, really flexible to allow us to do many, many different things and ways of building them and showing them off. So, you can see that we've got like menus and search showcased at the top, blocks and custom blocks. Promotes of content types, fields, views, end styles, responsive images. I'm not sure we've got responsive images in here, but a lot of this stuff is in the design. So, there are a couple of things that like maybe were in the initial design, but we've still not actually got into FOIA. We have static content, we have dynamic content and people can edit and do that. We have many boxes. Recipes themselves are categorised and targeted. So, we can categorise them by difficulty level. So, we're leveraging, tagging to do that. Lead images used for cars, but at least the images. So, we have a lot of photography that we've got, custom blocks and text fields. So, to be able to just contain the list item and then each item that you need to make a recipe or each ingredient is just a list item within the list. We could actually use our own fields for a piece and have multi-value fields if we wanted to do that, if we wanted to have a bit more flexibility with our content model. And again, this is the instructions for making the recipe, and that's another text field. We also have a related content in the design. We don't have that apart from buying the terms yet. It's like an example of a video demo that we have down here. These are very difficult to see. I do appreciate that, but we'll boot them up bigger when we're actually looking at this for wheels. A couple of challenges. The recipe content type is themes currently made around hard-coding things in template art. And we'd like to actually use something like field layout so people can do some work to do to actually use the full power of some three-fold features, especially more recent ones, like field layout. So, when we have a full layout tools, they will update farming as we go along to make sure it works and uses the factors. Also, the layout builder that's gone in is experimental. I don't know if everyone's playing with that. So, if we don't have that, I need to fight people at the moment. Once that's stable, we will then be rich. So, all this content is created by us so that there's no copyright issues and it's licensed to people. So, the photography, the recipes themselves. That gets around any kind of licensing issues because it's all going into core. We're going to extend core to sort of things like file image fields to the media fields going forward. So, media's just becoming stable in each point of time. It's not that much you can do at the part of a media browser yet. In core, we will have media. So, we're already working on how we can implement that changing our content of spring media. And then, because media's in, we don't just have to update what's there in the images and new videos to do that. It also gives us the ability to tap audio of a video so we can extend this by actually recording video recipes or blog posts or videos of people should it sort of come in the right way. So, it actually allows us to use more things that are in the public domain. We've actually changed the licensing model for Drupal in a day at that for the requirements of the Mami. So, the Mami, something as well as being built on top of Drupal, is also helping to influence some of what's going into Drupal. We can actually say, this will be better if we did this because it would help the Mami. Another example of that outside licensing is someone interested in migraines. Okay, it comes to my talk this time in D200 where we're going to talk about migraines. But, that is the issue to migraines source, CSB, so we can use the migraines module to migrate content into Drupal from a CSB file to migrate to actually build a lot of content out of the install because we have our own process to do that because we don't have enough back-end in core migraines to be able to do that. So, we're using that tonight to pull in another migraines back-end into Drupal stuff. Okay, so, actually building the demo. I can actually bring this up on PHP stone because it's probably a bit easier to do. How does that look? Is that readable? We can kind of see this. So, this is a checkout of just Drupal 8.6.x, the latest development version of Drupal 8.6, checked out with Composer Install Run and nothing else done to it. So, if we have a look in our core folder at our profiles, we can see as well as the minimal and standard that you'll see when you're installing Drupal normally and all these testing ones that are hidden but still used for testing purposes. We have this one called demo umami. And it doesn't really have that much in it to achieve this. We're not trying to show what you can do if you write like a whole metric ton of code. It's what you can do with Drupal mainly by configuring it. So, the bulk of what we have is just config that we're going to import when we actually install our install profile. That's lots of config I don't need to explain all these different config items and stuff. That would be a very little even dullness. We have some optional config as well. We have a bit of CSS, but we're not installing profile here. We're not in our theme. Why have we got CSS in our theme? So, we actually have a warning that we put up because this is a demonstration profile. We want to be really careful that someone doesn't install this and go, oh, that's brilliant. This is nearly like my site. What I'm going to do is I'll install this and make a couple of tweaks and then that will be my site forever. We do not want to have people building their live sites with this. It's for demonstration purposes only. If you ever talk to anyone who's done a lot of work with commerce, you know how many actual production sites are out there that used the commerce kickstart demonstration that was never intended to be production.  We really want to avoid that. There's a little bit of CSS because we put a warning in the toolbar. We tell people, if they're on an administrative page, we want to show them the thing saying, this is for demonstration purposes. We have a couple of other places where we try and catch that as well. When we come to, say, people at a point of service, say we've moved everything to the media. Say, well, I've moved it to the media and I've not filed it. If someone wants to use this ground for it, they might try and update it most of the group that they've installed it from. If no one should install something, as they want to say, I'm going to improve it. If we've changed how the marmig works, then we have to write migration pass to everything somebody would possibly do to the two different versions of the marmig that are wired together in different ways. The bad practice in 8.5 won't be the bad practice in 8.6 and 8.7 and 8.8. There's a lot of opportunity costs in white and info that we've done, and the only intention is not that we do that and that we don't incur that. Now, this is an ongoing discussion. Some people say it wouldn't be very good if you'd demonstrate something to somebody and then you could actually demonstrate upgrading to the next version of the same thing. That's a valid point. So we have some issues going back because there was a lot of discussion on that. It wants to make it clear to people that this... Presumably there is a way of, you know, so you can have my restaurant theme or whatever. So you can sort of force, potentially, the current status up there. So what I suggest that you would do with that is you could take the configuration you are interested in from your marmig, which will give you the content types. You can maybe borrow the theme, but the theme may be a little tightly coupled at the moment, and that's something that will keep an eye on going forward. It's like how tightly you're becoming the theme that we use when we go for this or actually what we do. Does it make sense to actually spin a lot of things with themes if you can do it by itself outside of the program? These are all ongoing discussions and valid points. There are some tricky issues around it. It seems to me a bit horrible to end up with an installed profile and then say, well, actually, no, you can't really use this. You too can achieve this if you put in lots and lots of hours and hours of effort, but we're not going to let you use this one, even though it's almost exactly what you want.  That feels almost worse than not having it. I don't think it's about to say it's worse than not having it, but I think it's valid. We need to be careful around the expectations here. We do let people know, so that's not the only warning we have. We'll see a bit that actually if you choose your marmig from the selection you will get a special warning that says this is the demonstration purpose of that. So, yeah, it's a tricky thing. That's some of the reasons. There's probably more than people who've been involved with it. And certainly, if you drop into our Out-of-the-Box channel on Google Slack and ask in there all certainly people who can talk around that to shop. All right, we're very friendly in that because we may have been talking about food most of the time. You've said that a lot. Unless it's late just before lunchtime. I'm just going to check that that clock up there is right. Yes, it is. So, yeah, so we have modules, but we only have this one module and the only purpose of this module is actually to install our dummy content. You can't install content through a bunch of config. And because we don't have that migrate backend we have custom code in here that is actually going to generate our content. And you can see that we actually have the HTML articles that we're going to install. I'm going to get back to it. And we have all the images and stuff. Notice that we've had to put HD access files in here because if we didn't then anyone who site was serving Drupal could actually be serving pictures of chocolate brownies. If people went to the right location there was a real consternation that someone could go to the White House website and serve pictures of brownies rather than serving from their own food blog. So, yeah. So if you actually do put this anywhere public facing and you're using a web server that isn't Apache, like IndianX or whatever the Microsoft thing is then you will have to do your own prevention to stop people accessing like the images that we have here that is built into our people constant. And also the recipe instructions themselves are in HTML files it makes. So we did start with everything in the CSV files and it made reviewing patches of changes to the recipes really, really difficult when your entire recipe is like one field in the CSV file. So I'll split those out.  We're trying to get stuff into core. You can't do that without actually showing that you've got adequate test coverage. And that's... And we also have a theme that is called Imami that has all the kind of usual themy stuff that you would expect to make your site look nice. So we have some challenges around this as opposed to when you're just developing a site for a customer. Because this is out of the box you couldn't go to Contra this is to show what you can do with just people. And also you can't use anything that's in an experimental thing. Don't you have experimental modules in core? They could go away, they could be removed. Some of them nearly work. I don't think any actually have them removed yet, but one of them was their institution. And the APIs of them might change as well. So we don't want to show people doing six months at the next release with Drupal. We wanted to show what you can do with stuff that is stable with Drupal and or included out of the box. We couldn't rely on any patches that might not get committed. Some stuff actually even wants to get to RTDC still though it gets committed back and forth. And we couldn't drastically affect the file size of Drupal. So it had to do a lot of... Because we can't just like 10 meg of lovely images. But we couldn't, you know, all this stuff was really nice and it keeps pictures of the lovely us. We could totally have like whacked into it if you made that everybody before Drupal or that load of Drupal would actually have to get as well. So it had to be really careful. Things like that. We couldn't... So we couldn't use those and places where that didn't bite us we couldn't migrate from CSV. We can't get what we get. We can't get into Drupal Core and say that we're working on a patch of data right now. We actually wanted quite that to use Playgrave to pull in there. That gives us the added bonus back to how we could really get examples of how to do a migrate in Core, which we don't currently have. We had to multiply and reduce the number of images. To make sure that's consistent we have a very strict process for that. So if you're proposing out a new recipe or a new image send the image to Keith and say you can do what you did with all the other ones. To make sure that we're using the same optimisation. So we have consistency across the aerospace and try to keep the custom code to a minimum. Our custom code is basically around some type of theme which we'll always do with the theme at the time and actually how do we know the concept and actually that people concept. Why don't we just disable that for installing it? Right, in the original plan Mark Connery was going to do an awesome bit talking about how all the themes were put together and then Mark's not here. So we're not going to do this bit. Just again, come in and slacken and ask Mark how the themes were put together or have a look at it. I'd like to do a couple of things around the template files. So I can't really do this but it looks nice. Accessibility, really, really, really important. There's a lot of considerations around here and a lot of our issues where we've done some really cool stuff and then it's kind of bounced back because we haven't fully considered the accessibility implications because we haven't really and jumped on all our stuff and making sure we're doing things like with how high enough contrast between background colours and foreground colours. Simple stuff, by far, is a real difference. We want to showcase the accessibility capabilities of Drupal now that we have standards that we've tried out back here to record. So it's a really good example of good accessible design and implementation as well. So it has to change those colours. We did some redesigning so I started off to make it that nice and accessible and also some style that I changed when it went back in as well as a basis of people that's accessible as possible. The accessibility issues, if they're raised they're considered a blocker and are not getting too stable. So we're actually committed into core but still an experiment of the bit and we've got the staples that would progress and unfortunately all the IE allowances only in time. What time is this supposed to finish? 10 to 1. OK, so we've got like 30 minutes. OK. So the process of getting into core has anybody here got stuff into core before? If they haven't, if you've got a core quicker, go ahead. OK, so lots of people have not been through that journey yet. So to actually get the profile itself into core we had to get approval from community reviews in our ideas and design ourselves and improve community review on Drupal's issues. Let's get product managers and framework managers to any reason that's a good idea in the first place and being that we're hit on missions and also accessibility as we said this is a stable blocker. So to get into core we had to address all these issues before it was considered fixed. And we had like several rounds of reviews to get this in and last year was some online presentations to all the product managers that short notice going through what we've done that really kind of kicked off their happiness to the marginalists to get into 8.5 when coming up to stability cruise for the 8.5 which is back in January. So we did get it committed to first to 8.6 because if it was committed to 8.6 perhaps a lot better to come out with that to see how it wants to get. So we had to address any issues that were going on to be using it. Now it's also in 8.5 we've shaken it out earlier when I said it's included it is there but you can't select it but we can get around that if you're actually on a plane. And the idea is that once people have gone and had a look at it and had a few more eyes on it we'll be able to go on and hide it before we get to 8.2. So maybe at 8.5.1 you will be able to do the gherry select if it's one of your installation options where it comes in. If you do have a plan and you see an initial design you will see that there's some things that we haven't entered yet. So we've done very much an MVP it's very cool in feature but there are some things that we haven't done yet. That's just time we've spent for it. We're going to do this, we're going to extend it as we keep this live as we go forward in core. Let's think about some of the things we're going to do in the future. Tor module Who's used Tor module? Okay so there was an initial plan that we would actually use some kind of custom block solution and Tor modules in core can actually build these features using stuff that's already in core design that we're going to implement there. You'll see that this is actually called something else and it's called an original version of this which is called salvo rather than rumami. Salvo just sounds the opposite of rumami. It's like what's happened to somebody when they're over rumami. So we're not doing that. Media we talked about not just actually converting our images to media but looking at the opportunities that has for including video and audio. Layout builder. We want to use that so we can showcase it. If you haven't played with Layout Builder it's awesome. It's found another way of interacting with your content rapidly. It's really nice. Migrates. As soon as we have that CSV setting straight. Setting straight has gone into core so we already have an issue to start playing now with that. How nice is that play with rumami? Setting straight is where it applies up on the site when you're doing configuration. So we've been playing with that if we've got any CSS. It's actually going to cause conflicts with that made that play nicely. Content moderation. We haven't implemented that yet but content moderation is now in core and what's really cool is that we've got a powerful piece of the group so we can actually come up with another language and have the ability to have the CSS language to play behind it. That's another huge boost to showcase the end of what we might be looking at. So if you want to get involved this is a really good project to get involved with core. We've got a whole bunch of people who've never contributed to core who have come along and helped out with recipes that have reduced the standardizations and I got involved in this because me, along with Phil Mawrthyn, I ran a Maccabe when the user group up in Manchester and to be honest we didn't have anything fine for January and we knew that people had been talking about the box just like a word so we had a look at the user group and we started to see issues with the recipes so people started to come to think of back to that and a whole bunch of people who never managed to get to me in true core thought out something that only like crazy people did. I haven't had a lot of arguments. Now me who's a developer from India has actually got a scholarship to go to Connord National based on his contributions to true core. So there's a load of ways to get involved with this. If you want to get involved look on the issue you've used for the component in the Mawrthyn effect demo or for tags out of the box that's the main two ways. Not everything out of the box has to do with the Mawrthyn demo for instance the issue to put the CSV, migrate back in that's an out of the box tag because it's doing it out of the box but it's not actually to do with the Mawrthyn demo at the moment. So check both of those. We have Out of the box channel on Slack every Monday at 4pm and that's just normally announced very close to the time in that Slack channel so if you hang out in that Slack channel and you want to get involved or see what's going on for you have any questions do that. Because we don't have that one. So we have here let's move this right that's the wrong one, that's migration that's tomorrow's look is that kind of readable let's go bigger so here we've got this is just folder that I've got here I've just checked out the latest 8.5.x and done a composer install and I have trust the database so if we have a look at what that looks like so 8.5.x and so I'm going to choose this in English oh that's standard and minimal can't see it because it's hidden but over here this is 8.6 latest version I've heard and if we have a look at this one standard minimal demo it's really tempting to do the umami in the Vic Reeves Uwabu voice which just derails any meeting or call that you have with it so here we have a demo and if you select this, this warning pops up for demonstration purposes only if you want to tell people about that and then save and continue and it's kind of like installing Dripal normally and it's complaining because I'm just using my local environment and Skol but we don't care okay that's going to go away and install so if you want to play with an 8.5 um back here you can install it if you use Drush so can we read this, can everyone see this at the bottom so let me up yep okay Dripal site can store and our profile is called demo okay we've got that yes Drush 9 nice is everyone using Drush 9? do you like it? yes okay have you had a look inside Drush 9? does it make more sense than Drush 8? cool right so okay that's that's installing Barley command line, let's see where everyone's up to we can do questions while we're doing this if anyone has any questions that we haven't reached so far just shout them out with me and if I don't like them I'll pretend I can't hear them this is all standard install stuff, nothing new here because it's a good question and the very point of this is to show what you can do with Dripal without adding anything to it once you move the capability to do that outside of Dripal you've changed your thing already and it's like what would happen with Dripal if we add some stuff to it there's some really good things that do that already there's a really good distribution called Barbase that has a ton of contrips configured in a really nice way if you haven't played with that go and have a look at it that's a really nice thing for actually just seeing it's got a nicer theme it has a load of stuff you might want to play with it has some exciting views back ends like those graffing stuff and loads of really nice stuff if you want to show what you can do with Dripal Acria have a product as well called Acria Showcase or something Acria demo framework that's it which is also a really good like here's all the bells and whistles here's stuff from Contrib but this is like what would this look like if we totally did it just with corp Barbase, let's bring it up if you go to Dripal.org Project, Barbase I haven't used this actually for any production things I spun it up and taken some really really good ideas from how it's configured found some really nice contributed modules for it it's a really nice version of Dripal that just works out the box you can even take it I think you can no it's not its own thing but this is done by a company that invested a lot of time in doing this and adding tests and stuff like that it's really worth playing with if you haven't done so far ok right what we don't know this is Umami, look at the 8.61 ok that one's finished as well so we have just to prove that this is Umami in 8.5 here we go right there's Umami so it looks like this well obviously we're on quite a wide quite narrow viewport but this is designed to be usable on mobile looks nicer Umami collapsed the nav and carrots articles about carrots who's interested specifically about carrots who's going to look at this and go oh there's carrots or there's brownies I'm brownies right what are we showing oh so we talked about things like that additional warnings so if we go to any page at Dripal considers to be an administration page maybe we're going to look at an article and we're going to edit it here's a list of articles draw your own herbs ok if we want to edit this oh no there's a total warning here so this site is intended for demonstration purposes ok so if you're actually so it doesn't show up because we're trying to give a demo from the front end and show you kind of things and we don't put this in your face all the time but if it looks like you might actually be trying to achieve something change something then we're going to remind you no there's something about this and at the moment this actually points to page on Dripal.org so you can go and get more information which might explain better why it's a bad idea to actually use this to build your site going forward ok so we have what we've got actually in this making it so we have a couple of content types recipe and this probably is exactly the same as the core article images tags recipe has a couple more fields author, cooking time, difficulty look we can use the build views tag so on so forth it probably has some shared configuration but there's no it doesn't actually inherit from the standard profile I think there might be some issues floating around in court about making profiles depend on each other I'm not 100% sure where that's up to again the proper people giving this presentation would be able to give you a much better answer so so we're kind of about out of time so we haven't actually had a look to play around with it but at least you know how you can spin this up have a look at it where you can go if you have any questions that I haven't been able to answer or if you want to get involved the more people we have helping out with this there's loads of things we need helping on in fact let's have a quick look at the issue queue for this ok this is just like the current status of what's going on with different things making things better, improving things adding new recipes we have a recipe for chili sauce that does not get gone on that I'm quite keen to get at but don't eat it unless yes so yeah so that's time so thanks very much and if you're interested in my great from my other talk tomorrow sit at the same time but in a different room thank you oh I thought we did the questions we can do more questions I don't mind oh quit another thing no no there we go complete aside just while I have people's attention as I said earlier me fell in arena run the use group up in Manchester come along we're always looking for people to come and give presentations and also in November we'll be running our third on conference we've done it for the past two years probably the first weekend but we're still finalizing venue and stuff cheap event no formal thing and anyone can actually come and talk it's a great alternative to camp style events because you'll see people you don't normally see get selected being able to give talks and you'll also see people you do normally see get selected trying out new talks before they try them in a more formal environment plus it's really cheap compared to camp events so do keep an eye on the NWDUG Twitter account for any announcements on that we'd love to see you up in Manchester in November or before that thank you I'm really good dude No, Sam's the only thing there for a bit Hey Baris Oden Do you know Liam? No My mind's certainly gone My mind won't work about So I was just wondering what if blinds asked you what if this looks like almost the rest of them won't just different followers So I would take a look at the the thing, just copy and paste it right you could create your own install profile you could import from standard and then import the config from umami you could there's a patch there's a module called config installer no, install profile generator so you can actually take a working site and generate your own install profile from it and that will tie you into the updates going forward so that's an option it would get the core updates not the umami updates so you can have the updates in the install profile so you still get your security fixes and stuff but you wouldn't leak in any changes that have gone in there so that's the kind of things that are the stuff yeah and then after we launched the umami thing came along well this is kind of 80% of what we just built you're the people we need to be careful for so yeah that's the kind of thing I'd explore certainly take it, use it, build it but don't use it as the install profile going forward well certainly there'll be a bunch of us who'll be at front end anyway because I'm coming to front end I'm sure Mark's coming in right he's been one of the main drivers so there'll be Larry might be but the other one the Spanish guy Ruben he's leading the sprints the Preston will be there as well but on your first day we might make it then in the IE 11 if we're at front end as well how's the planning going for that how's the planning going for the day before yesterday we got our main sponsor our main sponsor we have the main sponsor pretty well 925 we're safe with budget now that makes it we can spend more on making the events awesome wicked I'm really looking forward to it I'm really expecting 500 I think we can make that we already sold 250 tickets I'll better check I've got mine I'm not sure I'll catch you around hi thank you


The national broadcasting company presents Joe McCrae in tales of the Texas Rangers Tonight transcribe from Hollywood another authentic reenactment of a case from the files of the Texas Rangers The tales of the Texas Rangers starring Joel McCrae as Ranger Jayce Pearson Texas more than 260,000 square miles 50 men will make up the most famous and oldest law enforcement body in North America Texas Rangers come these stories based on fact only names dates and places are fictitious for obvious reasons They advance themselves are a matter of record case for tonight break down It is shortly after midnight the beginning of Good Friday in the year 1937 Jim Wiley constable of Romer, Texas is driving through the lonely outskirts of his territory When his headlights pick out a car parked on the road shoulder He breaks to a stop Having some trouble This he'd conked out on it I'm trying to get it started for half hour. Maybe I can get going for you. I know a little something about cars Okay, about trying you bet go here It looks like it ain't about to start friend. You must be out of gas the gauge says you have four Gage must be busted then Choked and like I did it should have flooded the car breeder gas was feeding through we get the smell of it Yeah, better take the tank Get a stick or something to shove in here for measuring with you. You bet This branch ought to do. Yeah, it's good enough. Give it here. She empty dry as a WCTU meeting Yeah, I leave me kind of stuff. Yeah, I got a siphon hose in my trunk We can drain enough out of my tank to get you back to Roma. Is there an all night station there? I'm afraid not no hotel either, but I can put you up for the night. You don't mind bunking in the jail What I mean jail, I'm the constable I see don't worry the jail is clean. Come on. Let's go get that hose Seem here someplace back to find it. I'm gonna match. Are you bet?  I can't hold this match much longer. That's another one Last one to book Well, you got that whole to have me no point getting snappy about it How come you didn't know the gas gauge in your car was busting? I Must just happen. I give seems to me.  I got it.   Come on on your fight.  Yeah, yeah, all you want try not yell at motor go ahead That's too bad You and me gonna make a trade Bullets from this gun exchange for your car That's mad at pop. Don't you like it? You'll get caught. They'll get you the cop ain't born can take me Come on pop.   I make it easy for you, but you gotta beg me a little You don't not give it to you through the kidney and that ain't nice pop Takes a couple hours to die that way and it hurts pop. I know I watched the cop die that way once before That's it pop pray louder. Let me hear you. You're the one I'm paying for you. Must be great Praying for me Cup, let's see who you pray for in the next couple It hurts don't it pop and it's gonna get worse You don't pass out till right near the end Enjoy yourself copper. Oh good time Constable Wiley's body was discovered shortly after sunrise when highway patrolmen spotted the stolen vehicle abandoned by the killer The sheriff was summoned and he called for the help of the Texas Rangers By noon of Good Friday Ranger Captain Stinson was at the scene accompanied by Ranger Jase Pearson While I didn't die is a Jase Look at that. Yeah, I tried to crawl out to the road on a blood trail must have been in agony every inch of the way Do you have any family an invalid wife two daughters and three grandchildren? The man who did this might just as well have shot them too. They'll feel the same pain while he did only longer With an alert out for Wiley's car. We might get a break killer may have been spotted in it somewhere along the line I doubt it. He probably got where he wanted to go and ditched it before Sunup medical examiner figured Wiley's been dead since about 3 a.m Must have been shot a couple of hours before then gives the killer a good start. All right, Captain. Yeah, let's get back to the room We've got one thing going for us though Man were after me have left some prints on the car. He abandoned when he took Wiley's lab men flew in before we got here They ought to be coming through with a report soon receive Clark is in town waiting for it You'll bring it out. I want you and Steve to stay on this case until it's cracked. It's one. I'd enjoy cracking Only lead we've got is that the abandoned car was headed west. Well, that's something at least you and Steve can start off in that direction Hey, here's Steve now Howdy Steve You get the lab report. Yeah captain. It'll rally your teeth here Killers been identified by fingerprints lifted from the car he ditched While he was killed by Rex Lang Rex Lang Yeah, no doubt about it. The Prince was clear as a bell is a copy of Lang's record attached to the report I don't have to see that. I know it by heart. I wonder how long he's been in Texas He might have been here for a year or more Last report on him was when he killed a policeman in Great Falls, Montana Before that he pulled jobs in Nebraska, Wyoming, and I always blaze quite a trail Yes, and I want that trail to end in Texas. It's the first time he's paid us a visit I want it to be the last he's not easy to catch According to that report. He's been jailed only once Idaho State reformatory when he was 16 as about eight years ago Yeah, and in that eight years he's killed six people four of them peace officers The first one was the guard at the reformatory Lang butchered him when he escaped Look at this record. Look at it Sent to the reformatory for beating his young brother half to death with a stove poker is that Lang's picture clipped on the report Yeah, a mud shot taken at the reformatory. Well, that'll help us. I don't know Steve a big-boned 16-year-old kid We're looking for a 24 year old man. He could have filled out plenty by now be hard to recognize Well, there ought to be some description since then ought to be but they're out all the witnesses. He's left a dead ones Is this the complete report? Yeah, that's it captain Oh except this probably doesn't mean anything the sheriff picked up this empty match book It was just lying in back of where Wiley's car was parked here on the shoulder Lab checked it for Prince, but they couldn't pull anything off of it. They all might have been thrown from any passing car Yeah, I guess so let me see it Advertising on the cover grand bowling alley in Pintato Pintato is about 70 miles west Jace And that's the way the car was headed He couldn't pick up matches before he got there Now unless he'd been in Pintato before and was headed back there again when he tripped over Wiley Well, that's possible our trail leads west anyhow do any harm to check around Pintato when we get there You're torn a double horse trailer Jace so you and Steve might as well ride together. So it's me I'll load my horse and put him in with charcoal. There's something about Rex Lang. It might pay to remember He was a ladies man back where he came from poke a till I don't hold Yeah, even then it was a high school girl who smuggled in the knife He used to kill the reformatory guard and have been indications They had a woman look out with him on burglaries where his prints have been found. I'll get my trailer open for you Steve Thanks, Jace Company for your charkey.   I guess we're ready to roll. You'll hear from us captain Jace Steve What's the matter captain? You both know Lang's record a killer with a crazy hate for all peace officers So understand that what I'm going to say now is not in order If you corner him, you'll have a mad dog on your hands, but I'd like to have him taken alive That may not be easy captain. I know but Rex Lang has become an idol to young punks and reform school toughs all over the country Now if we can put him on trial Convict him in the court of law and have him executed by the state It'll show those kids that society is strong enough to stamp him out like a flea There's nothing glamorous about dying in an electric chair But if you have to finish him in a fight he'll still be an idol He'll say Rex Lang was so tough. We couldn't take him. We had to kill him. I understand captain. So do I now remember? It's not in order.  Let's go We headed west looking for a dangerous kid grown into a dangerous man with a face We might recognize too late by midnight We checked the highway as far as Pintato in the morning. We started comb the town still drawing a blank That guy at the bowling alley was much help Jayce didn't seem to recognize that old picture Rex Lang And Lang may have changed a lot in eight years But if he made the allies a hangout the owner should have well, you know Jayce thought the face was a little familiar. Maybe yes. Maybe no Lang was blonde and smooth skinned as a kid here might have darkened plenty since then face and frame filled Out and he shaves now a beard line changes a face. Yeah Yeah, you might have just passed through here and picked up those matches though Maybe they were just thrown out of a passing car. I know we can't waste too much time on the lead that may be blind Yeah, how about some breakfast? There's a Mexican place across the street lobo. That's for me. I'm so hungry I'll even eat enchiladas for breakfast call this cross Easter Sunday to Marge is wish I could be home with the wife and kids I even forgot to order flowers. Why are the captain you have some scents of ours for you Didn't even think of that When is this party? Let's take the boot. Jayce. I'm tired. He'd not count The menu I have everything fruit juice couple of scrambled eggs easy with bacon coffee and toast When is this and your eta how will be with you in a moment you bet here I am starving. I don't even know what I want. Hey, why don't you wait on the lady while I'm thinking over? Of course and your take your time.  He gave me a choice And I guess I just double your order Jason. Yeah, what's the move and we leave here. I haven't figured it yet You know Jason, maybe we should go back wait a minute Thank you Sit tight Steve. Oh ma'am just a minute You speaking to me range it. Yes, ma'am. I Happen to look out of the booth and saw you don't I know you from someplace. I don't think so I think you sure look familiar you live here in Pintato. You bet I must have met you the last time I was through here about two years ago. I am a steak range I only been here six weeks. Oh, well, where'd you come from before that? What word that's your hometown you bet That's one on me. You sure did look familiar. Excuse me, please You bet We've heard the wrong. Can you read the note? Maybe grab your hat Steve? Something hit me when she was talking notice how she kept saying you bet Yeah, what about it that reformatory report about Lang the part about his habits you bet was his favorite expression Now wait a minute Jayce Lang me have changed but I doubt if he's turned into a girl No, but she picked up that expression someplace Steve from somebody who uses it regularly and it could be Lang Well, it's as good a lead as that matchbook Jayce. It's worth following. I think so too. Come on Let's see where she's taken that coffee You are listening to tales of the Texas Rangers starring Joel McCrae as Ranger Jayce Pearson We continue now with tonight's case breakdown an authentic story from the files of the Texas Rangers We followed the girl hoping she was taking the coffee to Rex Lang the hope exploded less than two blocks from Lobos cafe When she turned into the doorway of a jewelry store not far from where my car was parked Doesn't look like the sort of place we find Langy and Jayce and she went into the back of the store Look through that corner of the window. Yeah There's the container of coffee on that bench right beside the watch repair ma'am And she must have brought it in for him. Guess he's the boss looks that way and he can't be lying He must be 60 or more chase get back a little what is it? She came out of the bike. She's behind the counter now and she's working there then It's not taking any chances on being spotted drift back this way a little That's good enough. She'd have to come out to see us now Got to keep a tag on her. She's Lang's girl. She'll lead us to him Even if she is his girl no telling how often he sees her he's hot and must be hiding out someplace We could burn up a week or two and then find out we're sending our dogs at the wrong tree We won't waste any time not if we can get some information about her I'm gonna get to a phone. You stay right here on this block though walk the corner with me. Yeah Jason she was Lang's girl. Why should she be working if she was working in the laundry? That's a question I couldn't answer but I can think of a good reason why she might be working in a jewelry store Casing for Lang to knock it over. It's been done before I'm gonna have headquarters check back on some jobs Lang's pulled before see what you can find out along the street here She's a mighty pretty girl. So it's a safe bet. She's been noticed by other storekeepers along here Maybe one of them knows her name and where she lives Hey, so we don't want to tip our hand by asking too many questions Don't make them sound like official questions make them sound like you're just another man who's seen a pretty girl Okay, okay, but you ever mention this to my wife and you and me are gonna tang get going. I'll make my call and meet you at the car later I Called my headquarters and gave captain stinson a description of the girl We were tagging in a list of information I wanted was less than two hours later when he called me back What are they? Check cash and agency Girl fit into those cases. Yes, that's the modus operandi. I've been looking for that's as easy as dying her hair It all fits. That's where we want to be. Thanks captain. You'll hear from me I don't only give Lang a couple of more targets. Bye captain The girl was shaping up like the extra Joker in a poker game at the time I got back to Steve Clark. He had a rundown on her the name She was using in Pintato was Jojo Dearing That night the stores were open late for the last minute Easter shoppers But finally the lights went out and followed the girl to her home and staked out to wait Five minutes later. She came out again Hey, Jay's look. She's changed her clothes. Yeah, we're in jeans and a jacket now. Yeah, but why I don't know She's moving for a car. I'll let her stay about a block ahead They want to tag her too close with this horse trailer behind us, right? Yeah, she's pulling out now. So are we Steve I got a feeling we're moving in for the finish. Why? Why she's dressed not the way she dressed for a date in town But it is the way she dressed to go to Lang if he was holed up in some off-trail spot works during the week goes off to meet Them on Saturday nights. Yeah, Jason adds. We'll know soon enough. She's turning for the highway out of town Looks like a long trip chase Hey, where is she took a turn off up ahead and reach in the back and get a Tommy gun The captain said he wanted laying alive remember I know we have to stop that car later She picks laying up. I want to make sure we can put it out of commission. Okay Sorry Steve sharp turn off there grab a look at the map. Where does this road lead? I don't need the map This is state 61 nothing down here for more than a hundred miles except for a few run-down Mexican settlements I'm gonna cut off my headlights road gets kind of rough Jay's can't help it I can follow her tail light without her knowing we're behind her. Yeah, you're right Odd anything comes through here. She's scared a minute But she'll roll a lot easier if we weren't dragging that horse trailer I got a feeling we may need it No need for her changing her clothes like she did if she's gonna stay in the car Any place in here where she could pick up a horse? Yeah, about 10 more miles ranch owned by an old Mexican woman all she's got is a couple of horses And you think of any place near there where Lang might be hiding out Yeah, yeah about three or four miles back in the hills used to be a mine there a couple of them in fact They're abandoned Jay. Isn't there a road to the mines? No, nothing but a rough burrow trail It's tough country to get into if Lang's there. It's gonna be tough country for him to get out Just before we reached the old Mexican ranch We let the girls car pull out of sight we parked for 10 minutes then drove to the ranch Her car was there All right almost hidden in a clump of brush behind the barn There was a fresh horse trail leading into the hills we unloaded our horses and followed it Only by another half mile to the mines Jay she's heading right for more right something about this that bothers me Steve What's that? She stuck to the burrow trail all the way That's just what I don't like The only approach and Lang wouldn't be at the end of a clear trail unless he had some way of guarding it You mean he might have an ambush take that along here Man who hasn't been caught or even described in eight years doesn't leave his guard down I don't know he can't stay awake 24 hours a day Reckon not hey wait a minute hold up. Oh, whoo, Charky. Whoa boy. Whoa see something chase Yeah, brush at the side of the path been trampled not long ago either just bobbing back into its natural position Horse was waiting in there, and now we got two sets of tracks on the path That means he expected the girl waited here to meet her looks that way better get down lead your horse, right? Come on Charky Why did he come down to meet her? He didn't have to show her the way. They're still sticking to the path I don't know in one way. I wish the moon was a little fuller and in another way. I'm glad it isn't Hold it Well They left the trail here Brushes disturbed again the tracks turn in there. Come on. This is funny, Jayce We're following their movements through the brush and we're just making a little half circle right back to the burrow trail And look here.  Hey, Jayce can barely see it a piece of string running from the end of the branch that tree on the opposite side of the path Don't touch it. Let's see where it leads Look at that.  Look at the way that gun is sighted Anybody on a horse and move that branch get a charge right through the middle Anybody on foot who moved it probably get it right through the head You were right Jayce.  You'll have time say Jayce How about a toss to see who stakes out on the path? Why should you take the chance? Why not me because you forgot to wire the captain about that Easter plan for your wife and kids Get going after the horses and then get back here. Good luck. Jayce. Good luck to both of us, Steve I Planted myself in the path and waited Breaking into a sweat as cold as the ground Even if he thought I was dead at crazy hate-ridden killer like Lang might waste one more bullet A half hour passed an hour And then we heard him coming Slowly like a cat The gun was back and shot Right me here. What can't you see anything? Yeah, I See something look at that with the moon on it's a ranger Ranger Must be the one you told me about but you were so smart Said it didn't mean anything.  Yeah Please Whoever slept again, I'll make you an honorary cop. Come on Show you what you get. I Demonstrate on him I wish he was alive to feel what I'm gonna show you Make me look Now look at look Imagine what a bullet could do that pretty face I Got him see Like all that gun rex drop it. I said Here's your chance to try You want to get up try again rex or is that enough? Yeah It'd be a shame to split such a lovely couple I guess this isn't the kind of brace that you were after Joe Joe, but it'll have to do All right rex hold out your wrist Yeah, that doesn't change. Yeah Now let's get started. It's just midnight after we get him in a fast drive ought to get you home by morning and Give you a chance to pick up that Easter plant not only that I'll be on time to go to church with the kids you go Borrow a couple of words from rex You bet Tried as an accessory in the many crimes committed by rex lang joe joe Dearing was convicted and sentenced to a 50-year term in the women's prison at gory Lang tried for the murder of constable Wiley Slobbered and pleaded for mercy, but the jury gave no heed to his pleas as the prosecution brought his vicious record to light Found guilty of murder in the first degree Lang was sent to Huntsville Penitentiary where on the morning of November 4th 1938 he died in the electric chair Joel McCray and another authentic re-enactment of a case from the files of the Texas Rangers Joel McCray is currently seen starring in the Universal International Technicolor production Frenchy tonight's cast included Tony Barrett Bill Johnstone fire and Kane Herb Ellis and Betty Lou Gerson This story was transcribed and adapted by Joel Murcott and the program was produced and directed by Stacy Keith Hal give me speaking Three times mean good times on NBC There's fun excitement and prizes next on NBC as accordion playing emcee Phil Baker Gathers contestants around the microphone to see if they know the answer to America's favorite question What question is that why the $64 question?
