Hey guys, welcome back to my channel. As you can see I have a special guest with us today Do you want to introduce yourself? How's it going? I'm Brandon's boyfriend. My name is Corey. Yes, so this is Corey my boyfriend And he is here today because he is going to attempt. He's going to attempt To guess the prices of all of my well not all but a lot of my beauty products Ranging from low-end to high-end so he doesn't necessarily know what is low-end or high-end But he's gonna try to figure it out and basically guess what it costs to put this face together I don't know anything Well, you think you say you think you know you think you're gonna get it because you're a finance guy. That's true That's true. Yeah, he's a finance guy and he thinks he knows the cost of everything So we're gonna put that to the test Basically, he has to get within a $200 margin of the total cost of all of my products. So My nose is running So if he is above the total by $200 he loses if he's under the total by $200 he also loses Yeah, we're gonna go ahead and start. This is my first time doing a tag video. So You know, it's kind of fun because I get to do it with someone else not just by myself All right, so let's get started. I have my flash cards here And all the prices. So let's go game show style. I'm ready. You ready? I'm ready Get the uh The calculator out so that we can Add his total up and then measure it to my total in the end. All right So the first product is the Sephora radiant lumenizing drops, which is this product here You guys want to see I'll let you hold it so you know it you can Can figure it out I don't know what smelling it is going to do So I can just say the price just think yeah, whatever price you think it is lumenizing lumenizing drops Uh foundation moisturizer eye cream. I'm gonna say this is $12 $12, I know fine. I didn't see finance I actually forgot what the price of this was. All right, let's see $14 One for the guys. That's not bad though. Not a bad start. All right, let's put that in the calculator The next one is YSL lipstick Rogue pure couture. That's the full name of it. Okay. It's a little fancy What was it called YSL? It's a property I just don't know how to say it because it might be french or it's like st. Laurent or something like that. That's french. Yeah All right lipstick, right? Yep. Um, I'm gonna say $35 final answer All right 31 Not bad. Oh wait. Oh wait. Wait. That's something else.  Wait, let's see.  Sorry 37 Okay. All right. All right. Is that 35? I think 35. Let me mix it up now because I just jacked myself up The L'Oreal Paris Hydrogenous Hydrogenous daily liquid This is actually a new product. It just came out, but it's a face moisturizer Every morning and night after cleansing gently smoothing over face Let's see It's a glass bottle. All right. I'm gonna say This is $25. This product is 17 99. It's a drugstore product So it's a little bit on the lower end Even though drugstore products are trying to come up, they're, you know, increasing the prices Yeah, so but it's a it's a fairly priced product for the amount of product you get with in the bottle. So Next matte bronzer This is one of my faves. This is like I don't know Bronzer Bronzer sort of like tans your face Okay, $19 $19. All right, let's see. The next matte bronzer is only $899 Because next is not necessarily yeah, it's not a high-end brand But they have good quality low-end products I'm a little biased because I assume that everything you have is high-end I'm just like I'm just throwing out numbers based on that that bias. So Kind of gave away the you know what NYX is but it's another NYX product and it's their eyebrow gel This is another one of my favorites I brought a gel as you can see the tube is almost done. I don't think you're far off Yep, $699 Nice The next one is the urban decay poor perfecting primer guys Don't make fun of me. This thing is like busted. I busted the top off. So Don't be careful.  I was like it could be I don't know Next product is column the Too Faced Better Than Sex mascara Everybody knows about this. Yeah, buddy. Not me Pretty nice branding is nice. It is 23 But you know still high again, but you went over a little bit It's heartlet amazonian clay matt eyeshadow palette.

Okay, first of all, I would like to thank the organizer for inviting me to this brilliant conference. And this is, oh, where is it? Does it work? No? How does it work? This one? Where is it? Ah, I see. So what I'm going to speak about is this Bozanstein condensation. I don't almost see of the magnets in Ethereum Iron Garnet. And this is work which I made together with my former student, Pushan Lee, now post-doctor at Los Alamos, and another student, Chen Sun, and my friends and coworkers, Dr. Swine Seslow from Texas and the University, and Dr. Thomas Natterman from Cologne, from University of Cologne. And my sounds are to Sergei Democrito, who was the main person in the experiment here. Okay. Oh, sorry, I need previous one. So that is my congratulations to Boris. And on this, on this photo, you see that, on this picture, you see that Boris exerts some attracting force to other people. They lean to him. I'm one of multitude of people who experience this attraction, and I'm happy that our world lines crossed at some point, and I have a privilege and pleasure of communicating with him. Thank you, and many happy returns of your birthday. So what is, this is brief outline what I'm going to speak about. First, I will give a very brief introduction what is Ethereum Iron Garnet, and what is spectrum of magnets in it. Then I will describe the experiment produced on condensation of magnets in Ethereum Iron Garnet, because without that, it will be non-understandable what will be later. The third point is a theory for this experiment, and then I will speak about a new not yet published material, superflated of magnets. Only theory, no experiments so far. Experiment is in progress now. And yeah, conclusions probably, I hope that there will be time to read them. Okay, this is Ethereum Iron Garnet, it is very, what we need to know about it is that it is, do you see something? No, I don't, ah, oh, this is a very, very good crystal. Very good insulator, and therefore, spin waves in it are surprisingly, have surprisingly small line beads, and this is a best toy for experimenters in magnetism. They produce spin waves in it and transfer and made some interesting things and applications to that. I'm sorry, but I do not have time to speak about technical applications of that. Now, it is sufficiently complicated, it has sufficiently complicated unit cell with 80 atoms in it, and 20 of them are irons, there is ferrite with sufficiently high critical temperature and with big spin per unit cell, it's about 15. Now, the experiments on condensation were produced not in the bulk crystal, but in the film, and the film was not very seen it was about one to five microns, six, so it looks like it is three-dimensional situation, but in reality, it is not completely so because just at this sickness, the dipolar forces play the same role as exchange forces, and therefore, especially at very low energy. And therefore, the dipolar force should be taken into account very seriously. So the Hamiltonian includes not only exchange interaction, but also dipolar force and Zeeman interaction. Because S is big, Holstein-Prima-Kov transformation works well and all the calculations can be made explicitly, at least for the lowest energy band in which the spin of a cell rotates as a hole, okay? Therefore, this calculation for produced many years ago already, and the spectrum was calculated. The initial quadratic Hamiltonian contains not only a standard term in which number of magnets or number of spin flips is conserved, but also non-conservant numbers of spin flips here, so non-conservant magnetization. And that is due, these two terms are due to dipolar interaction, surely. Okay, all this, what enters in Hamiltonian and what enters the spectrum of magnets is written here. And as a result, we have, in contrast to the bulk spectrum, we have a spectrum which has two minima at finite wave vector q, q at minus q and maximum in the center, maximum at q equal to zero. This q is determined by dipolar interaction, also by exchange interaction. D is something like exchange constant multiplied by latest constant, by volume of elementary cell. And this is a sickness of the film, so this is sufficiently complicated combination, but in total, it has a value in the range of 10 to five inverse centimeters. Now, an important remark is that APA is an operator initially associated with the change of spin by one. Therefore, the operators of magnets which are linear combination of operators A and A dagger, in general, do not have definite spin, but fortunately, just near the minima where condensate is formed, u is very close to one and v is very close to zero. Therefore, condensate magnets have definite spin equal to one. Now, next approximation in the old stone expansion gives us the interaction of magnets and there are three different types of important interaction. One is the vertex with three lines which corresponds, in principle, to a decay of one magnet in two magnets, which is, which may be forbidden if the frequency is less than the doubled Z-man gap in spectrum. Now, next is the scattering process, two in two, they do not conserve energy and momentum of each, but they conserve a number of spin rays of magnets. And finally, one to three, these two, these and these interactions are due to dipolar interaction which does not conserve the number of magnets and this is forbidden if omega bigger than three delta. Nevertheless, it is very important for condensate because it contributes very unusual term to the self-consistent field. Now, I will describe the experiment. In 2006, the German group of experimenters in Münster under the supervision of Sergei Democrito discovered the phenomenon of both the condensation of magnets in Ethereum iron garand under the pumping. And what is also very important that this both the condensation happened at room temperature. So what is the basic experiment? They had a film of Ethereum iron garnet. The magnetization and magnetic field were directed parallel and they pumped magnets by a micro strip resonator under the film directly to Ethereum iron garnet. Because the electromagnetic field has momentum practically equal to zero, the only process which was possible or the most probable process which is possible was the decay of photon of electromagnetic field into two magnets with opposite momenta and with equal energy. Therefore, the energy of magnets was twice less than energy of photon. Now, the magnetic field was chosen in such a way. It is not unique way but you should satisfy this equation, this condition that this appear in magnets should have frequency smaller than doubled Zeeman gap, okay? Then the decay is forbidden and the number of these magnets is approximately conserved. Now, what they did after that, they considered, they observed how these appear in magnets, relax and form some equilibrium with condensate in the end. For that, they applied the brilliant light scattering. They had a laser focused in some point of film and the same lens collected the scattered light into some interferometer or filter which analyzed distribution of this distribution of these magnets by frequency. So that is what they observed in the left upper picture. Again, it disappears. In the left upper picture, you see the equilibrium distribution before they applied pumping. It is cut off because their filter had a limited band so it could not analyze further. Now, what happens after pumping? You see that the peak becomes more and more narrow and in the end, after 500 nanoseconds, the peak was so narrow that they could not resolve it. Okay, this is the same process but with angular analysis. And you see here that initially, they had a spot of appearing magnets. Then it becomes broadened in some range. The broadened increased, but after some time, it decreased and at 700 nanoseconds, it become very narrow near minimum. This point corresponds to minimum of energy in momentum space. So what is going on? I will present some simple theoretical ideas. And the first, they are based on approximate conservation of spin waves. Partly it was done by Bunkov and Volovykh. 20 years ago, they considered such a phenomenon in Helium-3. So the first important statement is that the pumping establishes a stationary number of spin waves of magnets, pump magnets, which is determined by the pumping power and the magnet's lifetime. So this is the pumped energy and it is divided by energy of magnet. Of pumped magnet, it gives the stationary number of. Now, then low energy spin waves relax to a metastable thermal equilibrium, but because they are conserved, this equilibrium will be with a non-zero chemical potential. Before of that, the equilibrium was with zero chemical potential because high energy magnets do not conserve their number. So they were able to confirm, experiences were able to confirm that what they observe is Bosenstein distribution, which can be substituted by Rayleigh-Jones distribution because the interest in energy are very small in comparison to temperature. Temperature 300 Kelvin at energy of Magnum, condensate Magnum is less than one Kelvin, approximately 0.1. So if you would have this distribution everywhere, the total number of magnets would depend on temperature and chemical potential. Initial distribution is the same but with chemical potential equal to zero and the difference between number of magnets with chemical potential and without chemical potential is just this fixed number of pumped magnets and you see here that it depends on chemical potential and this sum is converging even in three dimensions. Therefore, all these magnets are concentrated in low energy pumped magnets concentrated in low energy regions. Now, this is equation for chemical potential as function of number of pumped magnets. You see here that the chemical potential grows like as function of number of pumped magnets but it cannot overcome the gap in the spectrum because like in the standard was a conversation but in this case, the gap was zero so chemical potential could not be more than zero but here it cannot be more than gap in the spectrum and when it reaches the gap in the spectrum, this is just the signature of both a condensation. So the critical value of number of pumped magnets is just the difference between... So this value with mu substituted by delta. If the number of pumped magnets, if you increase the power of pumping and number of pumped magnets exceeds the critical value then the difference between the number of pumped magnets and critical number of pumped magnets fall into the condensate, okay? So you see here that the total number of particles in condensate also is completely defined by pumping power. Now, it explains why condensation is possible at room temperature. This is because the condensed particles all have the energy of the order of delta and delta is very small. Okay, six year later, the same experimental team made another very important experiment namely they improved the lens so that the spot of laser beam became less than wavelength of condensate magnets. And after that, scanning the laser, they could find how the density of condensate magnets depends on coordinate. This is this lower picture and you see very well seen interference structure. This interference is just the interference from two different condensate in the point Q and point minus Q. What was surprising in their experiment is that the contrast of this interference picture was very low, namely 3%. And I will explain next why it is so surprising. What brilliant scatter and see is it is local delta MZ associated with magnets. And if we consider only condensate then delta MZ associated with condensate contains of consists of is a square of modulus of wave function of condensate which consists of two superposition of two term from condensate in point Q and point minus Q. The square of CQ is a number of magnets in the point Q and this number of magnets in point minus Q and there is interference term with wave vector to Q. The fact that it is the wave vector is really to Q was confirmed by experiment very well. But if we would have NQ equal to N minus Q the contrast would be 100%. So that means minimum is zero maximum is something. But they had instead 3%. It can happen if one of two condensate is much smaller than another. If N minus Q for example is much less than NQ then this term is much smaller than that and we have almost constant. In particular when N minus Q is equal to zero there is no interference at all. So the question is why the symmetry Q to minus Q is violated? That is the first problem which should be solved. And that was solved in the work which we have published in the year 2013. And the idea was the following that the distribution of particles between two condensate is only due to interaction because the energy in these two points is the same. So redistribution without interaction would not change energy. So we can calculate the force order constant energy interaction between magnets and there are two constant characterizing this interaction. The constant A is interaction between magnets in one condensate, two magnets in one condensate. The B is interaction between two magnets in different condensate. And we have found that A is negative, B is positive for their conditions. If so that means that magnets in the same condensate attract each other, magnets in different condensate repulse each other. Therefore the ground state should be all magnets in one condensate, another is empty. But then if it is so there is no interference in the picture. So why interference appears? Okay, so let me write the most, it's almost most general equation for terms of force order. A and B are what we had before but there is also due to dipolar interaction. There is a term which contains one creation operator and three annihilation operators. You can take the wave vectors in such a way that some of all these wave vectors equal to zero. Take an account that you should, okay. What is the importance of this dipolar induced interaction is that it depends on the phase of the condensate. If you write that condensate is square root of number of particles times exponent of i phi, then the first two terms do not depend on this phi. But the third depends and in the ends we get cosine of some phase and this phase is some of these two phi. In the phi in the point q plus phi in the point minus q. Now you see that the minimum of energy definitely appears in the point when cosine phi is equal to plus one or minus one, okay. Cosine phi if c is a real number but you can keep it real. So that means that in principle first of all we have a phase coherence trapped phase between these two condensate. And secondly, what is also very important that there are two different states, pi state and zero state in principle. Okay, now imagine that we already made this minimization over phi and then what remains is the function of number of particles and q and n minus q. We should minimize this function under constraint that the total number of particles in condensate is constant. So what variable should be varied is only difference between number of particles in condensate and q and minus q. That can be made very easily because it is very simple. And the result is that the ground state depends on the criterion which is i minus b plus c. And if it is positive then the symmetric phase wins in which n q is equal to n minus q. If it is negative then non-symmetric phase wins. And delta is not equal to zero in this case. Now after that we calculated the phase diagram in the two variables. One is magnetic field, another one is magnetic field over, okay, this is magnetic field, this is sickness. Here are only small sicknesses but in big sickness practical only non-symmetric phase with phi equal to zero wins. So that is what now is available for experiment. But if we will have a sooner field in the range of between 10 and 20 then we will have first of all non-symmetric phase but with phi equal to pi. And secondly, symmetric phase with phi equal to pi. How much time do I have? Okay, not too much. Now I will show, so now after that I will show, I will should write the magnetization also in this form taken in account phases. And these phases also enter the interference pattern but not some, but difference. And this difference is a free parameter which simply shifts the interference picture as a whole. Therefore definitely doesn't change. The energy it is Goldstone variable. Okay, this is contrast, please note that it depends on model C and in the experiments A, B and C were like that. That gives for, according to this formula for beta, it gives beta equal from 2.5 to 5% and experiment it was from 3 to 10. And the theoretical reason for beta to be small is because QD is big parameter. In their experiment it was even not 30 but about 40. Okay, let me miss all that and that. Sorry, but I do not have time for that. But your slides are available from the program so people can see.  This is Goldstone mode. We calculated it, we have sound like dispersion which becomes quadratic, a big Q. And interesting that this velocity of sound is about kilometer per second for non-symmetric case. But for symmetric case it is about 10 times less. Now about superfluidity of magnum gas. There are two different obstacles to superfluidity. The gas is, the magnum gas, the condensate is coherent. Therefore seems reasonable to expect superfluidity but there are two obstacles. First of all that the normal phase overwhelming exceeds the superfluid phase by the number of magnums. Because all superfluidities in the range about 0.1 kelvin while we are at 300 kelvin. So the ratio of numbers is about 100. But what we discovered when we analyzed critical velocity and velocity in applied gradient of magnetic field that the velocities of magnum normal part which are diffusion in the force due to very small mean free pass is about five to seven orders of magnitude less than the velocity of superfluid part. And therefore the current will be mainly in superfluid not in normal part. That gives us an opportunity to consider superfluid part separately. But then we have a main obstacle. Main obstacle is that number of particles in superfluid part is not concerned. So instead of normal, instead of usual continuity equation we have continuity equation with right part proportional to sinus of angle. Phi. This N bar is the difference of N q and N minus q. And it is considered because it is Goldstone mode. Now the coefficient eta is very important here because it determines the energy barrier for which you can overcome. And then the motion becomes superfluid but not usual superfluid motion. And this N is C N square over eight divided by H that you see here for a little bit different for symmetric and non-symmetric case. Now what is new in comparison to standard superfluidity? First of all to get superfluidity you should overcome this barrier. So you should submit the energy to your condensate which overcomes some barrier energy which I have written before. Threshold energy. Now imagine that energy, submitted energy is only slightly bigger than threshold energy. Then what we should expect? If energy is small we know that the phase is pinned to zero or pi. Now if we have only small energy or only slightly exceeding the barrier we should expect that it will be pinned almost everywhere and changed by two pi on some solitons of phase change like that. So the phase is on long intervals is almost constant then changes by two pi then again the constant two pi times integer then again changes by two pi and so on. So the change of phases and therefore the velocity concentrated not only in condensate. So velocity is not constant everywhere. So how it can happen? It can happen because the dipolar interaction transfers the magnetization to ledges and then back. Why back? That is because the real processes are forbidden. Therefore you can get on with that. This formula shows how velocity depends on the length or the period of this quasi period of this picture and you see here that the energy is associated with this period and energy of individual soliton. They have different dimensionalities and that is I repeat this formula for. And finally I have shown the formula for the main wall width and the main wall energy and these are conclusions. So please read them. Thank you very much for your attention. Thank you very much.

We've got John A picking up the Mahomes Super Bowl 16 by 20. Congrats John. Mark L getting the Lin Swan Terry Bradshaw dual autographed helmet and David B picking up the autographed drone beddish jersey authentic as well. That is going to do it for the break guys. Thank you again. Next up we've got another one of these. We've got two, three more of these still, so I'm pumped. Let's do it.


Another centrality measure comes from thinking of our graph as representing lines of communication between nodes. Consider the shortest path between two nodes. Well, what do we mean by that? If the edges are unweighted, the shortest path is the one that passes through the fewest edges, and here's an important idea, might be one of many equally short paths. We call A shortest path a geodesic, and remember, there might be several paths that are equally short. So, for example, in the graph shown, let's try to find the shortest path between A and H. And we see that the path A, B, E, H crosses three edges, but so does the path A, C, E, H, and also A, C, G, H. So in fact, there are three shortest paths between A and H. And this leads to another useful centrality measure between those centrality. So imagine a message passing from one node to another. We might assume the message passes along the shortest path between the nodes. So a node that is on many such shortest paths might be viewed as an important controller of the information through the network. It's worth pointing out this isn't just hypothetical. Wars have started because of the influence of someone along the communication chain. So suppose we focus on a node. The betweenness centrality of a node is the fraction of the shortest path between the other nodes that pass through the node we're focusing on. Now like many things, betweenness centrality is easy to describe. It does take a bit more work to implement. So let's find the betweenness centrality of node C in the graph. So the idea behind betweenness centrality is if we want a message to go from one node to another, how many of those messages have to pass through C? And for that, we note that there are 10 possible pairs to connect. A to B, A to D, A to E, A to F, BD, BE, BF, DE, DF, and EF. And what makes betweenness centrality a little bit of work is not that the work we have to do is particularly difficult, but there's a lot of it. So let's get started. What we want to do is find out how many shortest paths there are and how many of those C is on. So from A to B, there's only one shortest path, so that we'll go in our shortest path column, and C isn't on it. Likewise from A to D, there's only one shortest path and C isn't on it. In A and E, there is a shortest path and C is on that shortest path. So that's one more shortest path and one shortest path that C is on. And between A and F, there's a shortest path and C is also on that shortest path. Now we look at the shortest paths between B and D, and there's only one shortest path and C isn't on it. So that's one more shortest path. Between B and E, well there's actually two shortest paths, B to D to E, which excludes C, B to C to E, which includes C. So that adds two shortest paths and adds one to shortest paths that C is on. And between B and F, there's one shortest path and that one includes C. Between D and E, there's one shortest path that excludes C. Between D and F, the shortest path goes through C. Between E and F, there's one shortest path that includes C. So there are eleven geodesics and C is on six of them. So the betweenness entropy of C is 611s.


Late in 2021, Xmonad released a new major version, 0.17, and 0.17 had a ton of new features built into Xmonad and the Xmonad-Contrib package. But Xmonad and Xmonad-Contrib didn't actually move to 0.17 inside Arch Linux until just a few weeks ago, so I'm still kind of new to discovering some of the cool modules that are available in the new version of Xmonad and Xmonad-Contrib. And one of the neat modules that's built into the latest version of Xmonad is the window swallowing feature. What is window swallowing? It is when you launch something from the terminal. The terminal goes away. It gets hidden. It gets swallowed by whatever new processes spawned until you kill that process and then your terminal comes back. Let me show you what I mean by window swallowing. So if I open a terminal and let me cd into a directory that's got some images and I'm going to launch an image inside fe, feh. This is an image viewer and if I open this image in this image viewer, you can see that the terminal is still open. I can't do anything in this terminal. It's a dead window because I launched this new process feh. I can't close the terminal. I can't do anything with the terminal. I can close the terminal, but if I close the terminal, feh gets killed as well because it's linked to the terminal. So what window swallowing will allow me to do is from now on when I launch something from the terminal, the terminal actually gets hidden and all I would see in this case would be the image viewer. I wouldn't have that dead terminal window taking up space on my screen. And adding this window swallowing feature to Xmonad is dead simple. I was actually reading the documentation for this and what you want to do is you want to import Xmonad.hooks.windows swallowing and then after you import this module, all you need to do is find your handle event hook and in that add this line right here. They give you the exact line to paste into your config and all it is is you add swallow event hook to your handle event hook and then inside parentheses, you're going to give it some class name. So these are what terminals do you want to be affected by the swallow event hook because it needs a proper class name. So if you use multiple terminals, you may have to do several of these class names here and then at the end inside parentheses, you want return true. So let me show you how this looks in my config. Let me get back to my desktop and let me open my Xmonad config and zoom in a little bit. So let me find the imports. So in the imports, all I need to do is I need to import Xmonad.hooks.windows swallowing and now let me go down toward the bottom of the document. So toward the end, I have the main block, this main do block here. And actually in my config, I actually didn't even use a handle event hook. I guess I was just using whatever the handle event hook is by default, like the default of settings for Xmonad because I actually didn't even have one in my config. But now I have added one. Let me turn off truncated lines here inside do me max because we couldn't see the entire line. But you can see handle event hook equals swallow event hook and then class name. So I have three terminals that I often use here on my system. So first one is class name equals alacrity with a capital A. And then this funny looking thing here is actually a less than sign, a pipe symbol, then another pipe symbol, then a greater than sign. But inside Emax, you have ligatures. So I get this fancy diagram, basically the representation of what this symbol actually is. It is actually this here if I'm looking at the browser. And this is just a separator for the next class name equals st-256 color for the st terminal, suckless is simple terminal. And then I also have this another separator and then class name X term and X term is capital X capital T term. And how did I get this? Well, let me run X term. So I'm going to launch X term. And there is a X utility called X prop for X window property. If I do X prop, my cursor turns into X. And the first window that I click on it will give me the properties for that window.  Let me make it full screen. And the text is all jumbled up. Let me try that again. It's up this time. Do it on a full screen window. There we go. And look for the line that starts with window manager class because that is what we need. We need the window class name. You've got two values here. I use the second value. You can see X T term, right? Capital X capital T term. So that is how I get the names for the terminals. So when I run X prop on a Lackardy, it's a Lackardy with a capital A. When I do X prop on the st terminal, it's st-256 color. So if you're struggling with getting the correct class name, just use the X prop command for that. And then once I add these two simple lines, let me do a colon W to write and let me tangle the file. And now let me restart Xmonad. And it restarts just fine. No error. So now let me go to a new workspace. I'm going to launch my Lackardy terminal here. And now let me zoom in just a little bit. I'm going to rerun what I did previously. So let's CD into this wallpapers directory where I have some images. And now when I run FEH on one of these images, so I'm going to view this in the FEH image viewer. Watch what happens to my terminal. It goes away, right? It's hidden. So all I have is the image viewer. And now if I hit Q and FEH to quit out of it, my terminal comes back. How cool is that?  I'm going to see if I can play one of my videos in MPV. So I'm going to CD into this directory here. And now I'm going to run MPV on one of these MP4 files. And MPV starts playing. Let me quit out of MPV. But you saw that the terminal went away. Now is the window swallowing inside Xmonad perfect? No. And they're upfront about this. If I actually go back to the browser at the top of the page about Xmonad hooks window swallowing, there is a note here. It reads, because the window swallowing needs to check the process hierarchy, it requires both the child and the parent to be distinct processes. And if they're not, I guess the window swallowing feature doesn't work. It mentions that many programs, the window swallowing probably won't work, especially some of the bigger complicated programs like web browsers. It actually is upfront about web browsers. And specifically, I have had people tell me that Firefox does not work with window swallowing. But oddly enough, when I go back to my desktop here, let me get back into the terminal here. If I launch Firefox from the terminal, yeah, I mean it swallows Firefox, just find the terminal goes away. Firefox is here.  So at least for web browsers, Firefox works. Now Brave does not work. You can see it actually does not swallow. And it takes me to the second workspace because I have that as a rule as well. A cute browser does work just fine with the swallowing effect. Let me quit out of cute browser. And let's check LibreWolf being based on Firefox. Since Firefox worked, I would expect LibreWolf to work. And it does. Let me kill LibreWolf. The terminal comes back just fine. I also have, I believe, Nyxt and Sold, the Nyxt browser. It swallows just fine. So all these browsers seem to work except for Brave with the swallowing. Most image viewers, your video player, MPV, all of that stuff seems to work. The one image viewer that does not work, which is unfortunate because it's the one I actually prefer is SXIV. If I launch the SXIV image viewer here on this particular image, you can see I get the image viewer, but it does not get swallowed by the terminal. And that is rather unfortunate. But overall, it works pretty well. I'm pretty happy with the Windows swallowing here inside Xmodad. I've already added it to my config, and I've pushed my latest config to my .files repository. I will eventually incorporate the Windows swallowing inside the Xmodad config for DTOS, although I haven't done that yet. But look for that coming in the next few days.

Attention five points residents. This is a community notification of a new sexually violent predator in your area. Please stay tuned to the following short program for more information. Hi I'm technician Ron Hackett with the Denver Police Department. The sex offender registration and compliance unit at DPD is responsible for the registration monitoring and tracking of all registered sex offenders and sexually violent predators who live in the city and county of Denver. Here's a brief history of sex offender legislation in Colorado. Our state laws trickle down from federal government mandates. In 1994 we had the Jacob Wetterling Act which mandated that states would establish a sex offender list. Megan's law of 1996 said that the public would have access to those sex offender registration lists. The Pam Litchner Act of 1996 stated that some offenders might have to have lifetime registrations and the Adam Walsh Act of 2006 unified sex offender laws across a country. In Colorado the legislature has determined that sexually violent predators by definition pose a higher risk to the community at large and therefore mandated that upon their release from the Department of Corrections the community must be notified. Sex offender notification in Colorado happens in two ways. The first is passive and ongoing through the sex offender registration process which is a list maintained by local police departments. The second way is active via community notification for those offenders determined to be sexually violent predators by the courts or by the parole board. Most sex offenders in Colorado are supervised by the criminal justice system in our communities. Most sex offenders engage in crossover behavior which means they may have been arrested for one type of crime but be apt to commit another.  There is no typical sex offender but all tend to be deceptive, manipulative and secretive. 80 to 93 percent of sex offenses are committed by someone known to the victim. Sexual deviancy begins in mid to late adolescence. Sex offenses are not impulsive.  The community has a vested interest in helping offenders to be successfully managed in the community. Sex offenders have the same need for housing and employment as any other citizen.  There are approximately 16,500 registered sex offenders in the state of Colorado. About 65 percent of convicted sex offenders are placed in the community on probation. The remainder are in the Department of Corrections or Community Corrections. Offenders may be caught for one type of offense but be at a high risk to commit another type. Crime of conviction is only one indicator of risk.  The offender's residence must be verified quarterly by the Denver Police Department. The full sex offender registration list is available by calling the Denver Police Department Identification Bureau at<PHONE_NUMBER>. Convicted felons and those with multiple convictions are posted online at denvergov.org slash police.   Now, here's a look at the newest sexually violent predator living in Denver. Here's an overview of the registered sex offenders currently living in Denver. There's 2,482 total living within city limits. In Denver Police District 6, there are 500. Precinct 612 has 169 registered sex offenders. Of those, 119 have felony convictions and 50 have misdemeanor convictions. John David Gravier is a sexually violent predator currently living in Denver. He's 70 years old and was born on May 18, 1949.  He's currently living at 1901 29 street number 24 in the five points neighborhood of Denver.

Two charges of sexual assault on a child, position of trust, victim 15 to 18. He's currently on parole and registered with the Denver Police Department on February 14, 2020 to 1901 29th Street number 24 in the Five Points neighborhood of Denver. Past charges against this offender include sexual assault on a child, disarming a peace officer, third degree assault, resisting arrest, parole violation. John David Gravier has been determined as sexually violent predator after meeting the following criteria. Criteria one age 18 or older on the date of the offense or under 18 and tried as an adult. The offender was age 61 at the time of the offense. Criteria two the crime must have been committed honor after July 1, 1997 and convicted honor after July 1, 1999.  The offender was convicted on November 16, 2010 for two charges of sexual assault on a child, position of trust, victim 15 to 18. Criteria three the relationship to the victim was one of the following.

The victims were a nine and 13 year old female. The offender was known to the victims. Criteria four positive results are the passing of a risk assessment instrument administered by probation parole staff and a qualified treatment evaluator. Positive results include an assessment for the presence of a mental abnormality, a level of denial regarding the offense, treatment appropriateness and motivation, presence of sexual deviant interests. The offender was evaluated by the Douglas County courts with positive results determining him to be a sexually violent predator.
