back to my channel. Today's video, as you can see from the title, it is going to be another Sheehan haul. Thank you so much Sheehan for sponsoring this video. I don't think, how about done a haul since I've been here? Like a sit-down haul? I don't know. I know I've been back there like trying on stuff but I don't know if I did a haul since I've been in my new place. But if you're new here, hey my name is Akira Jenae. Don't forget to subscribe and join the family before you leave. So we're gonna hop it right into it. I have a few cute pieces to show you guys. These pieces are definitely picked at random but it's kind of like an all-category type of haul. So the first one we're gonna start off with more so dressy like cocktail dress, formal dress, going out dress, like any type of formal event that you would need to go to is this cute dress. This one is what did I get this in? I think I got this in a size small. I can't ever find the tags. Yeah I got it in a size small. US size 4. It's this cute blue color. The straps are adjustable right here and this part it has lining in it. It is a little see-through but I think with just a black underwear or this type of blue underwear you should be fine. It is ruched on the sides and it also has not really a slit. It's kind of just cut a little bit above the knee and then it kind of just goes down. At first I really wasn't a fan of that. Like it looked really kind of odd on but honestly I feel like it'll just grow on me but this is a cute I feel like little bitty cocktail dress if you will. So I'll give this one about a 7 out of 10 simply because I don't like how it's just like a straight jagged cut and then just goes down. Like if this was a split like actual split and then the dress kind of went downward and flowed I feel like I would like that 10 times better. The next one staying on that formal type of cocktail dress or just you know formal dress is this cute V-line dress. It is backless. It has a zip right here on the side.  This comes in various different colors but I decided to just to get black. It is slightly big boob girl friendly. I am a triple D so this I just feel like if someone was here to really just tighten up the neck part for me since I'm here alone I was only able to do so much but if someone was actually to just tie this up really well for you I feel like it'll be fine. Probably was still maybe where some type of like push-up bra or little bitty cups that is kind of nothing in the back like it's just like the cups so probably would try that but this is super cute. Definitely pleasantly surprised with this one. It also has that little random jacket cut that kind of just opens as a split. This one isn't too bad rather than the blue one but this one I would give this dress a 10 out of 10. When I was kind of pulling on this it did feel like it was gonna rip a little bit though so definitely be careful with these strings because they are really thin but other than that like it's it's a beautiful dress. It definitely was not what I was expecting to get in the mail when I open up this package. I was definitely pleasantly surprised so super cute and I feel like this is just a showstopper. A lot of girls in their reviews were saying they weren't as a birthday dress. If my birthday dress from this other place didn't come in in time I would have ended up wearing this for my birthday. This came literally the day before my birthday so I may or may not be wearing this to a wedding coming up. If not I'll just wear it to whatever formal event comes up that I would have to go to or if not I will be wearing this for a date night with me and bae. I don't even care cuz what do I look like you know saving this for my birthday next year anybody could you know been in got this for their birthday so super super duper cute definitely give that a 10 out of 10. That's really all of my dressy stuff but since we are showing dresses I'm gonna show this a beautiful all-white. It reminds me of like a brunch dress like the big sleeves it's cute definitely something that I do not always wear. Y'all know with these within like about the last year I've been trying to pick clothes from Sheehan that literally is out of my comfort zone stuff that I would never have even imagined myself wearing and I'd like to pick different things because you know everybody don't have the exact same style as me and you know stuff like this this is nothing that I would have ever worn but you know some of my viewers y'all will like to see different things so I decided to pick this definitely pleasantly surprised I did get it in a size medium I definitely could have sized down to a small yeah it's a medium it's just the skirt part is really stretchy like look at that it is super stretchy so it's just a little bit big around my stomach but I feel like the arms in the boob part is really really nice I did put a safety pin right here because I wore bra with it on camera but I feel like you can wear a bra you can wear a bra or you can do it without a bra but what I did like is this little bitty rubber piece right here is to like you know stick to your skin to make sure this isn't sliding up and down absolutely love that it reminds me of like a bra so it's like when it's on you it won't be moving up and down and every which way so your boobs and your nipples can show so you just tie it up at the back put it on literally 10 out of 10 absolutely love this one definitely another one that I was not expecting to honestly really really like it was just something I saw on the side and I'm like you know what let me just try it so pleasantly surprised to get in as well my other item I'm gonna go ahead and show both of these together because I kind of wore all of these together this is a suit I did buy a suit I got it in a size extra small because everybody in the reviews was saying you know size down size down or like you can like really size down like basically a lot of people was in a extra small and I saw one girl on there literally she had a very nice shape and she had 10 times the amount of butt that I have so I'm like baby if she's fitting an extra small with all of that I can for sure fit in the extra small no I don't know what it is with women wanting their stuff extremely tight like depending on what the outfit is don't get me wrong don't get me wrong I love to have something you know tight fitting you know showing off the figure or whatever but a suit like first off the waistband does not stretch the pants itself is definitely stretchy breathable yes but it has a zipper on the side and a little hook like a bra hook on the side the pants I would definitely need a size small now medium would probably been too big yes I agree with that so I definitely agree with sizing down but only size down one size not to and the only reason I did get an extra smile was because I said I saw a few girls that had a lot of hips and stuff that was an extra small don't know how they did it okay but nevertheless I'm still want to get you some of this and I would like to get more in different colors this is such a cute outfit like they definitely did they begin with this one um obviously this isn't long pants to go all the way down to your ankles it's kind of like what y'all call them how waters we just call them like floods flooding pants but this is super cute the pants the waistband is definitely tight the jacket I thought was tight too but I feel like the jacket is you know doable it doesn't have a button or anything in the middle so you can't like close it together it's just a look that you have to have open and it have the illusion of having pockets but it is no pockets in this no pockets on the pants or the jacket and I really don't like that and I feel like there's something I mean like here something on my face but nevertheless it's super cute absolutely love and then I also paired it with this cute blue shirt I'm not gonna wear this together per say I just put it on together in the video because I didn't feel like going to get no blue jeans or anything to show this blue dress I mean to show this blue shirt the shirt fire this is super cute I did get my actual choose true size of medium but this shirt is so tight like obviously it has an elastic band like back here that's stretchy but this part since they already basically tied the shirt for you cannot untie it it is extremely tight right there so I would say actually size up if you want to get this one in especially if you have a boobs like I said I would have needed a size large in this I can fit the medium but if I want to actually be comfortable in like raise up my arms all the way and without my shirt riding up to my boobs I would definitely have needed a size large but nevertheless I'm still gonna wear it to give me a little cute pic or whatever but I probably will only be able to wear this one or two times because I should have got a size up so definitely size up in this it's super cute and baby the blue with that tan pants so I definitely gotta buy a blue shirt to work with it because baby it is fire never mind I think I actually got a fit to wear to like church or somewhere okay the last item that I have to show you guys it's just this cute graphic tee I know I wanted to get more into graphic tees especially with it being fall coming up next month I'm feeling this in August so fall it's gonna be here you know everybody loves to layer clothes and stuff so I just feel like this shirt was super cute it has a tiger on it I'm more of a lion girl myself but super cute the blue just popped out to me I don't know what it was with the blue for this clothing home but like blue was just you know it was just talking to me so yes this is the cute little blue graphic tee that I got I am trying to get more into wearing sneakers I am more of a heels girl and like my best friend she's more of a sneaker head so I have like all the heels and she'll have all the tennis shoes so I am trying to get into actually buying tennis shoes or asking for tennis shoes for like Christmas and stuff like that so I will need some more kind of like you know basic stuff graphic stuff because some of the shoes I won't have a lot of colors in it and I would think this would just be super cute with this so video before this one it was like just a regular clothing haul but this one is gonna be like swimsuit edition so this is not included go check that one out if it is disregard all of this so we're gonna start off with my favorite out of the whole haul it is this cute three-piece swim set I got this in a size of medium this is definitely giving tropical I tried this on and I am going to be going to Vegas in a couple months but I'm like this one is not giving Vegas it's giving like Jamaica it's giving somewhere in Mexico it's giving very much out of the United States okay so I absolutely love this one it's super cute like I said I got it in a size of medium the bottoms fit okay it's just the top I just wish that you can buy separate sizes like this is a medium I would definitely rather have had a large but nevertheless it's still gonna get worn and the girls are still gonna be out and then it comes with this cute long cover-up and this is what's making it give tropical vibes you know beach vibes somewhere that's not in the United States the vibes but this is super cute it's long it goes all the way from neck to ankles it does have some stretch to it like I said I got a size medium so it just feels comfortable obviously it's sheer it's a swimsuit cover up but honey 10 out of 10 across the board I absolutely love this outfit well this swimsuit so this is my favorite swimsuit at the bunch I say if it's true the size like I said I'm a size I'm a true size medium it's just my boobs are bigger so usually I will always have to like size up in that department but other than that it's usually always fine the next swimsuit that I got I only got two swimsuits in this haul but I have like a lot of cover-ups and stuff so y'all know my hair brand is brown so I love the browns so cute how stinking cute is this this is definitely giving kind of tropical to like more so Mexico to me but I'll probably end up wearing this one to Vegas and look at the cute little detailing on the little tie-up strings how stinking cute is that and then on the actual top it has the same decals are like a cute little starfish and then right here in the middle is the same little starfish and it's this is just so stinking cute the first cover-up that I had paired it with is this cute brown cover-up I got this one in a size medium definitely should have gotten a small it's just I didn't want to get a small because I had did that when I went to Miami before and the small that I had bought down there in Miami it was like skin tight I shouldn't own this one since it's kind of knitted it will be a lot looser but I did get in the medium nevertheless I'm still gonna wear it it's just this the arms is falling off of my shoulders the body part fits perfectly like a cover-up it's just the sleeves kind of falls off and falls down my arms but I will still give it a 10 out of 10 because it's super cute I wanted something brown to kind of match this and it looks amazing to me the next cover-up I got are these white pants I've been seeing these all around everywhere I got it in the size small my only issue is they don't go all the way down to your ankles it's kind of like your flooding in a sense and I don't really like that look so obviously I know it's a cover-up but I would have much rather wanted them to go all the way down to my ankles that's my only complaint other than that the materials good looks really nice so yeah the next one that I have is another pants cover-up this one I think goes all the way down to my ankles if not it's a lot closer than that one was obviously you still got that sheer going on this one is in a size small actually and these actually really like these are cute these kind of look like some pants that you will actually wear out somewhere if they wasn't see-through now my final piece that I have to show you guys is this very very cute one-piece swimsuit it you may not think it's a swimsuit but it's a swimsuit kind of looks like something you would go work out in or just a cute little everyday running errands romper super cute oh I actually got it in the size and medium it fits like a small this is in a medium and girl it is like skin tight so I saw some girls in the comments saying they just gonna wear this is like a little romper and go run errands I mean you could so I said I was probably gonna try to take this one to Vegas possibly because if we go to like a swimming pool or something or like anywhere close to some water or I know we are gonna go on the four-wheelers ATV riding or something like that I don't know whatever it's called riding in the desert I was thinking I may be wearing this because you know it's something that you can like really just get down and dirty and wet in and stuff like that so I think it's cute it also comes with two bra paddings in here removable and yeah it's just a little spaghetti strap it's not adjustable now that I'm looking at it like you cannot readjust these so I would say size up or get your actual size if you just wanted to be like tight it is a little bit on the tighter side down in the butt area but if that's what you like go ahead me I probably would have liked to maybe size up but I then I'm like would a large be too big so yeah I don't know but for the time being I would give it about an 8 out of 10 so that's all that I have for you lovely today comment down below what was your favorite item that I showed you as always don't forget to like this video comment and subscribe it helps me out a ton and subscribe subscribe subscribe we are almost to 30k a hundred k is to go but 30k we almost there so into my next video I will see you lovely spin bye guys


La Perm cat vs Turkish Angora cat. What are the differences between these two cat breeds? The La Perm's outstanding feature, of course, is his coat which has loose, bouncy curls, making it light and airy to the touch. Tighter, longer curls surround the neck, forming a rough and clustering at the base of the ears. The whiskers are also long and curly. The coat comes in two lengths, short and long, and any color or pattern. Tabby's, tortoise shells, and red cats are most common. Long haired La Perm's have a plume tail. The coat's length and fullness may vary seasonally. It sometimes parts naturally down the middle of the back. The short haired La Perm does not necessarily have a rough, ringlets, or earmuffs, and the texture of the coat may be harder than that of the long haired La Perm. He has a tail with fur that looks wavy, more like a bottle brush than a plume. The short coat may also part down the middle of the back. Whatever the length, the La Perm coat manifests in different ways. The kittens may be born hairless, with straight hair or with curly hair. Both long haired and short haired kittens can be born in the same litter. You may notice that the name on your kitten's pedigree includes the letters BC, BS or BB. Those initials indicate whether the kitten was born curly, born straight, or born bald and helps breeders study how the gene is expressed. The La Perm's head is a modified wedge shape, meaning it is slightly rounded. The medium size to large ears are slightly flared. Long haired La Perms have full furnishings, hair inside the ears, and a covering of fur on and around the outer ears that resemble earmuffs. Expressive eyes can be any color. The long haired Angora cat is not the source for Angora sweaters, although his fur is certainly just as soft and beautiful. This natural breed takes its name from the city of Ankara in Turkey, which was formerly known as Angora. The Turkish Angora is best known for its long, fine, silky coat, which seems to shimmer as it moves. The length of the coat varies, with the longest hair usually seen in the rough around the neck, the britches on the upper hind legs, and the plume tail. You may think of an Angora as being solid white, but the coat can also be other solid colors as well as tabby, tortoise shell, calico, or other patterns. Beneath the coat is a body that is firm, long, and muscular. Legs are long, with the hind legs being longer than the front legs, and the paws are small, round, and dainty, often with tufts of fur between the toes. The long tail tapers from a wide base to a narrow end.  The eyes can be blue, green, gold, amber, or odd, one blue eye and one green, green gold, or amber eye. Today the cats are recognized by most North American cat registries. Hello. This video is sponsored by Beemix Pets. Are you looking for high-quality cat collars at an affordable cost?

Often described as clownish, he is something of a mischief maker who makes talented use of his paws to open doors, swipe things he wants or tap you on the shoulder for attention. He's not clingy, but he likes to be with you and will follow you around, sit on your shoulder or the top of your computer, or sit in your lap, whichever option is most convenient for him. He is moderately active and enjoys retrieving items that are thrown at him. Despite his reputation for getting into things, a law perm is pleasant to live with. He rarely uses his voice, and he is affectionate, gentle, and patient with his people. Most are also welcoming to visitors as long as they were well socialized as kittens. Beautiful and elegant on the surface, the Turkish Angora can surprise an unsuspecting owner with his athleticism and intelligence. No bookcase is too high for him to reach the top, and no closed door is safe from being opened by his questing paws. While he certainly can have lovely manners, Turkey, as he is sometimes nicknamed, has an active, boisterous side to his nature, with a cleverness that makes him endlessly entertaining. He likes to play and will do whatever is necessary to get and keep your attention, even if it means getting into a little trouble. The Angora keeps his kitten-like playfulness well into old age. He is friendly toward guests but loves his own people best. This is a sociable breed that is best suited to a home where he will have another cat or a dog to keep him company if people aren't home during the day. When you are home, the Angora may drape himself across your shoulders or settle comfortably into your lap. At night you're likely to find him next to you with his head resting on your pillow. To live happily with a Turkey, you should have a sense of humor that matches his own, as well as a good store of patients.  If you will, it's best to consider another breed. This is an affectionate, gentle cat who is devoted to his family, but his precocious intelligence, resourcefulness, desire for interaction and play, and short attention span may make him a challenge to live with. The law perms unusual code is easy to care for and usually doesn't matter tangle if it is combed or brushed one to three times a week. Longer coats should be groomed more frequently. Use a comb with revolving teeth for best results. It will go through the coat easily without straightening the curls. To keep the cat looking his curly best, miss the coat with a little water or fluff it with damp hands to set the curls. The coat sheds little, and shedding is further reduced with regular brushing. If small mats develop, brush them out gently with a slicker brush or greyhound comb, stainless steel with narrow teeth at one end and wider teeth at the other end. If you give the law perma bath, press a towel against the coat to soak up moisture, and then let him air dry in a warm, draft-free spot. Even a blow dryer will give him a bad case of frizzies. The Turkish Angora has a single coat with a silky texture. Because there's no undercoat to cause mats or tangles, it's easy to groom with weekly combing or brushing, and it sheds very little. The coat doesn't achieve its full length until the cat is approximately two years old. Brush the teeth to prevent periodontal disease. Daily dental hygiene is best, but weekly brushing is better than nothing. Trim the nails weekly. Wipe the corners of the eyes with a soft, damp cloth to remove any discharge. Use a separate area of the cloth for each eye so you don't run the risk of spreading any infection. Check the ears weekly. If they look dirty, wipe them out with a cotton ball or soft damp cloth moistened with a 50-50 mixture of cider vinegar and warm water. Avoid using cotton swabs, which can damage the interior of the ear. Keep the litter box spotlessly clean. Cats are very particular about bathroom hygiene. It's a good idea to keep law perm and Turkish Angora as indoor only cats to protect them from diseases spread by other cats, attacks by dogs or coyotes, and the other dangers that face cats who go outdoors, such as being hit by a car. Cats who go outdoors also run the risk of being stolen by someone who would like to have such an unusual cat without paying for it. The easygoing but playful law perm is well suited to life with families with children and cat-friendly dogs. He can learn tricks, enjoys interactive toys, and loves the attention he receives from children who treat him politely and with respect. Supervise young children and show them how to pet the cat nicely. Instead of holding or carrying the cat, have them sit on the floor and pet him. Always introduce any pets, even other cats, slowly and in a controlled setting. The Angora who has been well-socialized is comfortable with kids, making him a good choice for families who will supervise children to make sure they pet the cat nicely and don't pull his fur or tail. He is happy to live with cat-friendly dogs, too, as long as they recognize that he's in charge. Introduce pets slowly and in controlled circumstances to ensure that they learn to get along together.

So, we know that organic acids HA dissociate into H plus and A negative. A negative is what we call our conjugate base. I'm just going to write CB. Our organic acid dissociates into H plus and A negative mainly because of two reasons. First, that HA bond is not that strong and the other reason that A negative, our conjugate base, is stable after dissociation. Alright. As our conjugate base becomes more and more stable, our HA molecule becomes more and more acidic. Let's talk about our A negative stability. The idea is that we'll be comparing the stability of A negative of two molecules, molecule one and molecule two, which of these molecule is more acidic. As the stability of A negative increases, the acidity of HA increases as well. Now, because our A negative is an anion, we need to stabilize our anion as much as possible. In our previous video, we have studied about something called electronic effects. In this video, we'll be checking the stability of our anions or our conjugate base using these electronic effects because an anion can be stabilized or destabilized by electronic effect. We'll be mainly focusing on aromatic stabilization, which is way more than resonance, which is more than inductive effect. As we go about our examples today, we'll see how anions are stabilized by aromaticity, resonance and inductive effect. From here, let me show you the molecules I have for you today. This is one of the molecules like this and the second molecule I have is this. This is a connected, yes. One is cyclopentadiene, and the other one is cyclopropene. To compare the acidity of this molecule and this molecule, we need to first write the conjugate bases of these molecules. Let's start with cyclopentadiene. Before I start removing hydrogens, I need to check which of the hydrogens will be lost most easily. We have one hydrogen here, one hydrogen here, one of it here, and one of it here. The other kind of hydrogens we have is this. Why do I say other kind? I say it because hydrogens over here, here, here and here are equivalent. The effect that these hydrogen will cause after they are lost is similar. While when this hydrogen is lost, they are equal. So we have two types of hydrogens. One where the hydrogen is connected to an sp2 carbon and one where it is connected to sp3. We find out that these kind of hydrogens are the most acidic hydrogen and we make our conjugate base. Our conjugate base looks like this, where the negative charge is born on this carbon right here. We know that an sp3 carbon bearing a negative charge is highly unstable. But wait, I can see that this is a cyclic molecule. I can see a chance of delocalization of this negative charge over the entire molecules because there is pi bonds connected here. Let's try and do that. If I try to displace this negative charge over here, this makes our pi bond shift to this edge and gives us a structure like this. Right? And then I can do the same over here, make it shift right here and it will look something like this. And the same can go over here. The same thing happens again. It looks something like this. What I can see here is that the negative charge is delocalized over the entire molecules making each carbon sp2. Right? I can see that all our carbons are sp2 because of this resonance. See, here we had an sp3 carbon but as the delocalization began, this carbon also acquired sp2 hybridization. Same happened with all the carbons in this molecule. I remember if a molecule is cyclic and if all the carbons are sp2, the molecule becomes planar. A planar molecule being cyclic opens the possibility of aromaticity. Over and above this, we need one more rule to check if there is aromatic stabilization of this molecule. We call that Huckel's Rule. Let me erase some part of this screen so that it gives me more space to write. Let's do it over here. Okay. So because we have Huckel's Rule, Huckel's Rule says that the number of pi electrons, pi electrons and lone electrons should be equal to 4n plus 2 where n equal to 0, 1 or 2 and 3. Let's check how many pi electrons and lone electrons do we have in this conjugate base. We have 2 pi electrons here, 2 pi electrons here that gives us 4 pi electrons and how many lone electrons? It has negative charge so it means it has 2 lone electrons which gives us 6. I want you guys to pause the video and check if 6 satisfies the 4n plus 2 rule. If I put n equal to 1, we will get 4 into 1 plus 2 which gives us the magic number 6. So yes, this conjugate base is aromatic and as a molecule is aromatic it gains a lot of stabilization. So it's safe to say that our conjugate base is very stable. But before I come to the conclusion if cyclopectadiene or if cyclopropene is more stable, I need to check the same for the next molecule. We have cyclopropene which looks like this. Before we start writing its conjugate base, let's identify which of the carbons will lose its hydrogen most easily. We have one hydrogen here, one hydrogen here and the next type of hydrogen we have is here. I say these two are similar because both of them are connected to sp2, here as well as sp2 and here it is sp3. So let's lose the sp3 hydrogen and see how it looks. But a carbon which is sp3 is highly stable when it has a negative charge. The only way it sustains this negative charge is due to resonance where the negative charge is delocalized to this spot and the pi electrons move to this point making it look something like this. I have a negative charge here and the same happens over here again. If you remember from the last time I can see a similar pattern happening here. Right? So a cyclic molecule having all its carbon as sp2 now, here it was sp3 but now because of resonance, this carbon also becomes sp2. So it's a cyclic molecule, it has all its carbons as sp2. When I say sp2 it essentially means that the molecule is planar and because the molecule is planar there is a continuous pi electron. That means the delocalization is happening all over the molecule. The third rule we need to check is Huckel's rule. Why don't you guys pause the video and check if this molecule satisfies Huckel's rule or not. I am going to clear off this part. Huckel's rule says there should be 4n plus 2 pi electrons and lone electrons. Let's count how many pi electrons and lone electrons do we have in this conjugate base. We have 2 pi electrons in this pi bond and 2 lone electrons in this negative charge. So we have 2 plus 2 which is 4 and there is no possible value of n which can give us 4. Even if I put n equals to 0 it makes 4 into 0 plus 2 equals to 2. As this molecule does not follow Huckel's rule, this molecule is not aromatic. As this is not aromatic but it still has resonance stabilization but as we saw in the sequence we know that aromaticity provides the most stabilization followed by resonance followed by inductive effect. Our molecule cyclopentadiene and cyclopropene as this molecule followed Huckel's rule it gained aromatic stabilization whereas cyclopropene is not aromatic. The conjugate base of this molecule becomes more stable than this conjugate base. So we can say that cyclopentadiene is more acidic than cyclopropene.


Next session this morning, another one that may seem like it's a little on the remedial side, but I think you'll find some value in it, is about Zen, Zen server and Zappy, what's the difference? The two suspects up front here, I'm Russ, I'm Zen evangelist, so that means I have a big mouth and I know where the airport is and I know how to use it, so I run around talking about Zen to whomever and James? My name is James Bourpin, I work for Citrix as head of technology for the Zen server product group and I'm going to help Russ to untangle what's Zen, what's Zen server and to follow up on some of what Ryan talked about a little bit about what XCP is. Alrighty, so this is the basic question, everyone knows what Zen is until you start talking about it and I found this out the hardware, the hardware, I started it as the evangelist for Zen project back in January now and I've been to I think like eight or nine different conferences this year talking to people and inevitably, you know, I stand up, I give my talk about one thing or another and I engage other people afterwards and oh, we're talking about using Zen, etc. and generally 10 to 15 minutes into our discussion, something like a version number will come up and I'll realize they're not talking about the Zen project, they're talking about Zen server or they're not talking about Zen, they're talking about Zappy. So we just want to spend just, you know, 20 minutes here kind of drawing the lines so people understand where they are because it's fuzzy and we understand it's fuzzy and it's fuzzy because we've made it fuzzy, so we're just going to try to clean it up just a little bit and get rid of a little bit of the confusion. So what's Zen itself, the Zen project? The leading open source hypervisor and if you don't believe that, I'll give you the web page where you'll say exactly those words. You know, it's open source now and always and you know, this was two years ago, this was the great misconception that, you know, Zen was dying, Zen was closed source, Zen was a Citrix product. No, Zen is now open source, will remain open source and it's now part of the Linux Foundation collaborative projects so it will very happily and proudly remain open source. Thank you very much. We're celebrating our 10th anniversary. I mean, if you look at the timeline, which we'll get to in a second, it actually started earlier than that but this is 10 years since the first open source release of Zen itself. And as someone mentioned earlier, you know, in industry years, that's a millennium. You know, anytime you can get a decade and it's still running strong and it's also home for several sub-projects, which we'll talk about very briefly. So here's just a short pictorial history. You know, it started with this thing called the Xenoserver project and if you go to the zenproject.org web page, you can actually see some of the original documents that came out of the design. How many people have been to zenproject.org? Okay, good. How many people have accounts there? Okay, the rest of you have homework. It's easy and we won't pester you. And the other thing is we also have a nice little monthly newsletter that just gives you news of the month. So it's, I mean, it's very light. We're not talking about junk. So in case some announcement came out that you're unaware of, it's a nice way to get kind of up to snuff in three minutes. But anyway, so you can find that information out on the website. We see, you know, the initial release.  We see the release of a ZenCloud platform, which James will talk about in a few minutes, and on into now.  Also, there's more detailed history out on the website. So there are actually several sub-projects under the Zen project. The one that everyone knows, hopefully, is the hypervisor. It is the main game. It's why we're here. Then there's PVops, which technically is not a sub-project, but it is what allowed us to get rid of all those nasty Zen kernels that you had to install. It was brought out in, I think it was Brian's talk earlier, that once upon a time you had to do a lot more. Because of the PVops project now, it's just part of Mainline Linux. So you don't have to do any funny tricks. That's wonderful. We talked about the hypervisor. The Zappy project. We're going to hear about that more in detail later. The Mirage OS, which was talked about earlier as well. This is just wonderful ability to have these small, lightweight, dedicated, little library-based operating systems so that we'll do one thing and do them really well, really quickly, and really lightly. Really neat stuff. Once again, if you go to zenproject.org, we've got all sorts of information out there about that as well. But all of this comes under the auspices of the Zen project. Now, here's a picture that you've probably seen more times than you care to think about if you've attended any Zen talks anywhere. But this is the basic design of the hypervisor. And just to be very clear, because this comes out all the time, it doesn't actually run in the kernel. We see that it sits right on top of the hardware. The bits that are in the kernel, or excuse me, not in the kernel, but what we have sitting above the kernel is the control domain, which can then talk to the hypervisor. And it includes in there the device drivers and the models. So that's all that's necessary there. One of the big takeaways is that since it's not sharing, it doesn't have technically a host machine, the Zen VMs never compete with processes. They compete with other VMs for resources. And that's different inside some other hypervisor schemes. So that's really important to know that it's not a question of how busy some other VM is. It's at the VM level, not the process level. The architecture emphasizes security, and anyone who was at my security talk yesterday, we went through some of the details about that, how that's going to be accomplished. If you weren't there, you can find the slides right now on the Linux Foundation website, and they'll be out on zenproject.org within a few days. And then the use of various tool stacks, which we'll talk about a little bit more too, as this session goes on, for the control domain. That allows the control domain to talk to the hypervisor. The fault currently is XL. If you read older literature, you may see references to XM. XL is sort of XM on steroids. So, you know, go with XL when you can. Well, you do see, you know, we do have support for Libvert and Bersh. So I mean, if you're working in an area that wants to talk to KVM as well, that becomes kind of an easier way to converse. And there is no native GUI, as we've heard earlier. However, there are some very interesting things coming, and notably, Zen Orchestra, we'll be talking about later this afternoon, and a little bit about Zen Center here later in this talk. Zen Project has a number of corporate members, and these are some very notable names up here, and they are all vested in the success of the Zen Project. So if anyone ever tells you that no one cares about Zen, wrong. Just take a look at this picture, and there are some companies that care quite a bit about Zen. We can add one more to that now. We can add NetApp to that now, who joined very recently. Excellent. Okay, I didn't have that on there. Thank you. So I mean, you know, these are people who care for a reason, and if your company isn't up there, and you're doing a lot of work with Zen, you should be asking yourself the question, should our company be talking about joining in the corporate members? It's a really good thing to do. Now, zenproject.org, as I mentioned, it's the hub of information for the Zen Project. So, you know, it's newly revamped and revised when the Zen Project went to the Linux Foundation in April. Zenproject.org came on online. The big thing about it was that we wanted to start being able to reach out to both developers and users. If you remember the old Zen.org, very developer-centric, we wanted to stop that. We wanted to have the information the developers need, but we wanted to make sure that you also had information that users can use. So we've got the new monthly newsletter, as I mentioned, and sign up if you haven't, because we won't pester you right now. It's just a once-a-month thing, and it has no fluff. We don't like fluff, so we're not going to pitch it on you. And then, of course, there is the Zen Project mascot, because a cuddly panda is a terrible thing to waste. And you'll see him all around and so forth. So, and in fact, one of these days, we get around to having a contest to actually name him. We don't actually have a name for this fella. So, you know, keep your eyes open to the website and the newsletter. We may announce a contest soon. But if all of this is Zen Project, then what's Zen Server? Hi. Very good question. Thank you very much. So just actually, while we're on the panda here, this is perhaps a good opportunity to plug the Zen Developer Summit in Edinburgh next month. Edinburgh actually now is home to two pandas, I think, one on loan from China. So if you want to see a real proper life-size panda, that's not quite as fake as the tux that's wandering around downstairs at the moment, come to Edinburgh next month. Anyway, so what's Zen Server? Well, Zen, Zen's the engine, is the way we like to think about it. It's the thing that does the hard bits, the virtualization. It's how you can run multiple VMs on a piece of hardware. It's that low-level tool stack. XM is the CLI's ND. More recently, XL and LibXL, the Zen Lite stack. So what's Zen Server? Well, Zen Server really is a distribution of Zen and all the other components you need to make a virtualization platform. So as we saw, for those of you who were in Brian's talk earlier, we saw there was a kernel in there. We saw the picture with the DOM zero and the kernel running in that. You need to choose your Linux kernel. So that's an important piece. You need some sort of tool stack. You can stop with XL, that's fine. You can write a configuration file, run XL, create a point of that configuration file, go make yourself a domain. What we do with Zen Server is we add a tool on top called Zappy, and I'll talk a bit more about what that is later on.  So really what Zen Server's doing is bringing all the pieces together that you would ordinarily have to put together yourself in a generic Linux environment. Now, we sometimes use the term shrink-wrapped. So it's something you can just take out. And as we saw in Brian's talk earlier on, you can just install this thing onto a box and not have to even worry there's Linux in there. In fact, when Citrix started doing Zen Server, a really called Zen Enterprise back in 2006, the intention was to target Windows admins who we thought would be scared by the Linux internals. So we actually did our best to try and hide the fact there was Linux in there. So we're building on those basic virtualization foundations to add a higher level of system management. Some places we're overlapping with what cloud orchestration stacks are doing. Obviously, Zen Server predates OpenStack and CloudStack and so on. So now there's kind of a choice of different ways to orchestrate your system. So Zen Server, if you like, kind of overlaps a bit with what the orchestration stacks are doing. But there's an awful lot of value added there. So history-wise, we've actually got quite a long history, not as long as Zen. 2006 was when it all started. Zen Server started as a proprietary product of Zen Source, which was a startup that was later acquired by Citrix. It started off very, very basic, with a very small number of customers. I'm going to talk about a very small number. I mean, fewer than we have people in this room. But we've really come on a long way. So Zen Server 6.2 is the most recent shipping product from Citrix. I'm not going to go for a product pitch here. That's not my intention. But that is now a free product that's available for anyone to use all of its features for no charge. Citrix sells a support contract. I'm not going to plug that, but it's very good. And at the same time, we announced that we would be moving the entire of Zen Server to the open source. Now, a number of the pieces had been open sourced already. But this is really just finishing it off and also moving to a more open development model. And for those of you who missed my talk on Monday on the evolution of Zen Server from an open source perspective, the recording of that will hopefully be available soon, if not already. So a little bit about some of the pieces we have, and I'll just nod to the open sourcing as we have a quick look at these. We've got a currently based Zen Server on CentOS 5. It's 5.7, I think, in our most recent shipping. So thank you, KB, for providing that for us. We'll be moving to CentOS 6, probably 64 for the next release in less than six fives out in time. And obviously the Zen 4 CentOS 6 work that Brian told us about earlier on is something that's actually very useful for building the foundations of Zen Server. There's all sorts of other stuff in the box. Storage management, we had a bit of a discussion in the earlier talk about some of the different ways to manage storage. So there's a piece in there, a lot of Python for the control plane. The PV drivers, para-virtualized drivers are device drivers that are aware they're running on top of a Zen hypervisor, but they may actually be running in a fully virtualized guest virtual machine that doesn't know it's being virtualized. So that allows us to get much higher IO throughput. So we actually have Windows drivers that were previously proprietary than they're now becoming open source. There's the Zen Center UI. A Windows, I apologize, .NET based application. Again, we were targeting the Windows IT admin. So we actually originally had a Java UI that was compiled and packaged for both platforms. So, but we moved on to the .NET UI ready to satisfy that particular market. There's also other stuff in the box. So a lot of stuff that actually it's all a lot of open source stuff in there, but stuff that we were not really developing in an open way, big patch cues only published in source RPMs when we published the binary. The thing that we're moving towards now is having everything be an open source project on GitHub or equivalent where that's not suitable and everything's being done in the open. But I won't go into too much detail on that today because we don't have time, but do talk to me or have a look at the video of my talk for Monday. So, zenserver.org. So ZenServer, just to be really, really clear, the Zen project, which Russ talked about, the Linux foundation collaborative project. ZenServer.org is the open source home, the community home for ZenServer. That is not part of the Linux foundation. So Citrix has not given ZenServer the Linux foundation. That's something that we don't think the Linux foundation would want it. They don't host Red Hat. They don't host Ubuntu. They don't host CentOS. And ZenServer basically being a custom Linux distro. They don't host ZenServer either. So zenserver.org is a Citrix-led project. A lot of what we're trying to do is to get things out into the open, open communication, feedback, discussion. What we really want to be able to do is to enable our ecosystem. We have a lot of partner companies building add-ons and services around ZenServer. So actually removing a lot of the barriers is key here. So zenserver.org, there's kind of two things we do. ZenCenter probably being the most obvious one. The UI. The Windows PV drivers are in there too at the moment. But it's also a distribution. We are hacking the what's it out of CentOS 5 at the moment. For which we are deeply sorry. But we've had to make a lot of additions of newer packages, lots of patches. We're trying to move away from that. But at the end of the day, we are doing the job of a distro to some extent. So we're doing that distro job. Management, choice of versions, and so on. As part of zenserver.org. But also, within the ZenServer development team, we are contributing to other projects. So we are using the Zen project. We are using the Linux kernel. But we are making changes to those in order to deliver what we need in ZenServer. So the developers are working within the upstream communities. QMU is another one. There's a few others as well. In order to get the code in we need and then consume those projects within ZenServer. Citrix ZenServer is a commercial product built off of the open source code base. Citrix will be releasing, as it has done for the past seven plus years, a stream of versions of ZenServer. They are now all, as I say, free, all features are free for use. You only pay for support. But you don't have to. We don't have any of the SKU limiting that we had before where the free version didn't have HA, which is something we talked about in the earlier talk. OK. So, Zappy. What's Zappy? We talked a little bit about that. It's a tool stack for managing a Zen system. It adds a higher level of management than the low level LibzenLite tool stack we have at the moment. So LibzenLite really is about taking existing storage, existing networking, Linux bridges, OBSs and so on, and starting and managing the end using those. ZenServer really is orchestrating the creation and mapping and everything that's involved in setting up those entities, managing clustering in a multi-host environment, coordinating the high availability failover and so on. That's actually been open source since 2009. That itself is actually part of the Zen project. It's one of the sub-projects that Russ talked about earlier. And we have, as Brian talked about in his talk earlier on, that is also packaged for Debian and Ubuntu. We've had tech previews of the CentOS package, and I hope we have something a bit more formal on that fairly soon. So, this is one that you wanted me to cover, wasn't it, Russ? Oh, yes, this is something. So what is XCP? Well, this term became rather overloaded. We used it when we first open-sourced the Zappi tool stack back in 2009. The term has come to mean two distinct things. One is a synonym for Zappi itself. So you type app to get installed XCP Zappi. So that's become, the Zen Cloud platform is kind of the selection of packages, Zappi, ZenObsidy, Storage Management and all those things. So that's fine. The other thing that has come to mean is a binary distribution which looks very, very much like ZenServer. So I often call it XCP.iso and it basically is a ZenServer with its branding removed and a few proprietary packages removed. A few proprietary ones left there actually on the Windows drivers. Now that specific use case is kind of evaporated now ZenServer has become completely open-sourced. So following XCP 1.6 and ZenServer 6.1 which are basically the same thing we've converged the two to become ZenServer 6.2 and there is an upgrade path there. And one of the things that that will enable is when Citrix publishes hot fixes for ZenServer previously people have had to unpack those by hand using GPG and stuff extract at the RPMs to apply them to XCP we will be able to have those hot fixes applied to people using ZenServer in an XCP-like fashion. I believe at the moment we are limiting the automation through ZenCenter but ZenCenter is open-sourced and we all can replace if statements if we wish. So that we think will and also helps because we're removing the delay on the XCP releases. It took a very long time if I recall to get XCP 1.6 even though it's basically the same as ZenServer 6.1. So Russ there's a lot of information here. Yes, and there's two minutes left and just because you came here and you thought it's a conference it's easy it's quiz time. So we're going to see how good your knowledge of ZenZenServer and Zappy is. Here we go first question ZenZenServer or Zappy? Let's hear it. I'm listening. I'm listening. ZenZappy answer Zen is the ZenProject mascot. But that also I guess does cover Zappy. Somebody very very on the ball here. Yes, very good. Next question. This is a picture of ZenCenter. Is that ZenZenServer or Zappy? Correct answer. ZenServer. ZenCenter is part of ZenServer and that is now open source. Open at Citrix now what falls under the auspices of a Citrix open source project is that Zen ZenServer or Zappy? ZenServer very good. Linux Foundation Collaborative Projects ZenZenServer or Zappy? Zen and Zappy. Zappy is a sub project. So it's still under the Linux Foundation Collaborative Project. So that was a tricky one. Now here's a lovely one. The Xe command line is that part of ZenZenServer or Zappy? Here are all three. I hear Zappy. It's Zappy. The Xe CLI is part of Zappy. And by extension ZenServer for those that said that. Now here we have the Excel command line here. Is that ZenZenServer or Zappy? The answer is Zen. The Excel command line is part of the ZenProject stack and yes you can use it in ZenServer and so forth. We don't always recommend it though. You will be treading on the toes of Zappy. So be careful. Oh well. Then I put a nasty in there. Sorry about that. Okay here's the extra credit. QMU. Is that ZenZenServer or Zappy? Answer a trick question. It's its own project. We just use it. But it's not technically part of the ZenProject. It's not part of any of these projects. So anyway, thank you very much.  So thank you very much. So we're going to take a five minute break. Is Larry here? Yes.


This paper proposes a demand-based UAV scheduling scheme for urban low-altitude logistics operations. It uses an improved simulated annealing algorithm to optimize the delivery cost and delivery time while accounting for various constraints such as UAV performance, airspace constraints, and distribution constraints. To verify its effectiveness, two urban air traffic networks were constructed using real-world data from Shanghai. The results showed that the proposed model outperformed other forecasting models in terms of delivery cost and delivery time. Additionally, it was able to flexibly calculate the optimal scheduling scheme under different parameters such as delivery volume, delivery distance, and UAV performance.

Video Friday without resin. Hey everyone, it's Friday, which means it's video Friday, and today I am going to answer a question that we get asked every single day. Do I really need to use a torch to get rid of bubbles? So I just wanted to show you a couple of the methods that are kind of floating around out there. All right, so the first one is blowing out the bubbles. So some people suggest blowing through a straw to, you know, get a more concentration of air. Oh, look, you can see it hasn't done anything. And in fact, I actually blew the resin right off the side. I've totally ruined my doming here. It's dripping down the side. Blowing not super effective. Maybe if you have something really tiny, like you're working on jewelry, it might be effective.  So don't blow the bubbles out. Okay, the next thing, a lot of people talk about hairdryers or heat guns. Okay, when you think about a hairdryer, it blows hot air. So what do you think is going to happen to your wet resin? You're going to blow air and dust and bits of hair and junk in the air all over your wet resin. So don't use a hairdryer. Heat gun, maybe a little bit better, but still let's take a look here. So the bubbles are popping a little bit. But look, you can see it's all those ripples there. It's pushing the resin. Right. And look on high. Again, the bubbles are coming out, but it's pushing the resin.  And it's again blowing hot air. You could be blowing dust and all kinds of other stuff in the air into your wet resin. So really your best bet is to use a torch. Honestly, trust me, it's the best, best, best tool for the job. You can use a little butane torch like this one here, or for a big piece like the canvases behind me, you can use a propane torch. So I'll show you. I'll just turn it on here. Okay. So this is like super effective for a big canvas for something small like this little butane torch is perfect. So I've got our artist torch here. I'm just going to turn it on. Okay, look, it is getting rid of all these bubbles, but notice the resin is not moving at all. So I can go right at the sides here. It's not pushing the resin off the sides. It's not ruining my doming. And those bubbles are coming out so beautifully. Perfect. So I don't know. I think the results speak for themselves. If you really want to use the best tool for the job, it is a torch. Anyway, that's it for Video Friday. Join us next week. Video Friday with that resin. I think that's over.

Ranger Bill, warrior of the woodland, struggling against extreme odds, traveling dangerous trails, showing rare courage in the face of disaster, in the air, on horseback, or in a screaming squad car. Ranger Bill, his mind alert, already smile, unswerving, loyal to his mission. And all this in exchange for the satisfaction and pride of a job well done. Boy, oh boy, we finally made it, Central City. Now, don't get so excited that you forget to watch where we're going and get lost, JoJo. Aw, Mom, it's just that I wanted to get to see Central City for such a long time, and every time I have a chance, something seems to happen. I guess I shouldn't worry about you getting lost, not in that hat. I don't think you like my Sherlock Holmes hat, Mom.  That's all. I'm not playing Sherlock Holmes. I just like this kind of hat. I just think it looks silly, but go ahead and wear it if you must. Well, now that we're here, I'd like to get a lot of shopping done. Well, Mom, let's go around and see the sights. We'll do that a little later. We have all day, you know. Right now, I really do want to stop in this store and look around. Boy, some fun. I might just as well be back in Naughty Pine going shopping with you. Speaking about being back in Naughty Pine, JoJo, look over there, across the street. I didn't know he was coming up this way. We might have ridden with him. Where are you looking? Over there, see? In front of that men's store. Bill, hey, hey, that's Ranger Bill over there. Only look, Mom. He's not in his Ranger uniform. Why don't we run over there and say hello? If he isn't too busy, maybe we can ask him to have lunch with us. Oh, boy, that's swell. I guess he doesn't hear me. Hey, Bill. Good morning, Bill. Hey, hi, Bill. Are you addressing me, young man? Yeah, sure. Oh, come on, Bill.  I thought Stumpy was in charge of the joke department. You two go ahead and talk while I stop in this store to look around. Okay, Mom. Come here, JoJo, when you're through. Okay, okay, Mom. Why are you out of uniform, Bill? Uniform? Uh, I'm afraid you have me confused with someone else. Bill, don't you recognize me? It's JoJo. Are you all right, Bill?  Now, please leave me.  Oh, come on, Bill. What is this, a joke? Young man, this is not a joke. And you call it. You have me confused with this Bill person who I am not. Now, if you will not leave me, I will leave you. Hey, wait a minute, Bill. That is Bill. I'm sure of it. I wonder why the brush on. Hey, I know. He must be on some sort of secret assignment. He didn't dare recognize me. Wow. I wonder what it is. He sure did a good job of pretending he didn't know me. Almost gave me the creeps to see someone you know who says he doesn't know you. I wonder if I should follow him. No, better not. Probably a pretty important job if he isn't in uniform and isn't supposed to know anyone. But maybe he'd go somewhere where it would be safe to talk. No, I shouldn't get in his way. Maybe someone would see us who shouldn't and then... Still, maybe I could help him if he ran into trouble. I guess maybe I will follow him at a safe distance. Just in case he shouldn't need help all of a sudden. Jojo, where are you? Jojo? I wonder where he went. Yeah, boy, I told him to come straight in. Hmm. Well, I hope he doesn't get into any trouble. But I doubt whether he would with Bill. Besides, he has Franny's address in case he gets lost. He'll probably meet me there for lunch. Well, as long as Bill is entertaining Jojo for a while, I guess I can get some more shopping in. Boy, looks like we're getting near the waterfront. All these warehouses. I'm starting to feel like Sherlock Holmes way up and following Bill. I don't even think he knows it. I've been out of sight every time he looked around. Whoops, almost missed his turn in there. I'd better hurry. He turned this corner. I'd better peek around the corner first. There he goes into that big warehouse. I don't see any signs on it. Must be a secret meeting place or something. Boy, I wonder what kind of assignment he's on. Must be exciting. He's gone in. Boy, now what'll I do? Maybe I'll just move a little closer to that warehouse. There just might be a window open or something. Maybe I could just take a little look inside. You never know if Bill might be in trouble in there or something like that. Is that you, 16? Yes, 13. I just came in. I'm coming right up. You took longer than expected. I was beginning to worry. I was nothing to worry about, 13. I simply took my time and did a careful job. All went according to plan. Good, good. Do you have the papers? Right here in my inside jacket pocket. Excellent. They will be happy to get these. Are they the right ones? I'm sure of it. They're exactly where they were supposed to be. I, of course, know nothing of this kind of material. Nor I. But I'm sure these are the right ones. Excellent. They sure are very impressive a lot. They're very full of information. They have gone to a great deal of trouble to get them. That in itself speaks highly for their importance. Yes. And how good that nothing has gone wrong. I too, I'm glad. But... But what? As I was on my way back here with the papers, a young boy and a woman addressed me. It was purely a case of mistaken identity, but he was very insistent. Kept saying something about me being out of uniform. That is indeed strange. Did he follow you? I made it quite clear that I was not this bill person that he mistook me for and walked away. He protested no further. Well, maybe it was just a case of mistaken identity. As long as you were not followed. My knowledge? No. I am sure it was only a harmless incident. We cannot be too careful. These papers are too important to be mistaken about such a thing. I do not think he was an agent. It was only a young boy with a funny hat. A funny hat? Quite unusual. It had peaks on both ends and somehow tied its side flaps at the top. It is difficult to describe. It does not seem probable that an agent would make himself quite so obvious. My thought exactly. It is why I have passed off the whole incident as precisely what it appeared to be. A case of mistaken identity. These papers spell riches for us, 16. You had better get busy microfilming them. It would be a sad day indeed if something would have happened to them this late in the game. Yes, of course. And while I am microfilming them, you had better go out and get our plane tickets to get us out of the country. Yes, that is a good idea. Fortunately, it is not hard to get plane reservations in this city. Possibly we could be well on our way tonight. I hope so. The sooner the better. Now that we have the papers, there is no need for our waiting around. In fact, it would be better for us to leave immediately. And I will hurry to get these papers microfilmed and hidden. What? The alarm. Someone is trying to get into the warehouse. This is the first such attempt. For a moment I did not know what the alarm sound was. Quickly, turn on the television camera. Let us see who our visitor is. Right. While I am operating this camera, you would best get those papers out of sight. Ah, it's beginning to focus. I'll hide them here. In the waste basket? Good idea. Now let's see who is intruding in our privacy. What? Look, climbing that back window. It looks like... That young boy who stopped me on the street. He must have followed me here. That is right. And perhaps we have misjudged his importance. Perhaps he is not just a harmless boy with a funny hat. He is inside. He seems to be alone. He is shutting the window now behind him. I think we had better go down into the warehouse and welcome our young visitor. What's the matter, old timer? Not getting enough sleep these nights? No, it's not that, Bill. It's just that it's a doll around here. Doll? Sure. Look at it this way, Bill. Henry is away at camp. It ain't very good weather for forest fires. Even Paddlework and Jojo Jones are away. Just ain't anyone around to cause a little excitement. I don't know how to take that, old timer. I'm still around here. Oh, sure, sure. But you and me, well, we know each other so well. We've been together for so long. It's like I'm talking to myself when we talk. I feel the same way, Stumpy. Disaster is struck. Somebody's in trouble demanding our attention right away. Why don't you just answer it and see what it is? I know what it'll be. Someone in trouble. Fapped on a ledge for weeks with undead but eagle eggs. Ranger headquarters, Stumpy Jenkins speaking. We specialize in rescues. It's for you, Bill. Long distance. I'm sorry, old timer. That's all right. Bill Jefferson speaking. Bill, what are you doing in Naughty Pine? Oh, hello, Mrs. Jones. I don't quite understand your question. I just wondered what you're doing there. And where is Jojo? Really, Bill, I thought you would have been more considerate. Excuse me, Mrs. Jones, but maybe we'd better start from the beginning. I don't quite follow you. All right. After you and Jojo talked today, where did you go? Already. I'm lost. Jojo spoke with me today? Yes, today. This morning, here in Central City. There must be some mistake, Mrs. Jones. I haven't been in Central City for weeks. Nonsense. I said hello to you here myself. You might have said hello to someone who looked like me, Mrs. Jones, but I can assure you it wasn't me. Well, I'm sorry I couldn't help you. I'm even more worried. If Jojo isn't with you, where is he? Well, maybe we'd better start again. Fill me in on anything you can, if you will. Certainly, Bill. As you know, Jojo and I were going to spend the day here in Central City. That's where I'm calling from. Well, we arrived here this morning, and we're doing a little shopping when we saw you. At least we thought we saw you. Well, Bill, it looked so much like you that I didn't even question it for a minute. I said that Jojo should ask you to join us for lunch. Then I went into a store to look around. When I came back, Jojo was gone, and so were you. At least the man who looked like you. Uh-huh. Uh, what did you do? Well, naturally, I thought Jojo was with you, and I didn't worry about him. I just went on shopping, figuring we'd all get together. Probably my sister's house. Jojo knows her address. That's where I'm calling from now. So anyhow, I just went right on shopping. And you say this was early this morning? Yes. I'd say about, uh, nine or 9.30. Bill, it's after four now, and I haven't heard from Jojo at all. That's why I called. Hmm. I really don't know what to tell you, Mrs. Jones. You'd think Jojo would at least try to contact you. Unless... Unless he's in some kind of trouble? Is that what you were going to say, Bill? Mrs.  Stompy and I'll hop in the Ranger Cub and fly up there on the double. Maybe between the three of us, we can locate Jojo.  I'm really getting worried. No word yet, huh? No. Bill says you think that Jojo is wandering around with someone who looks like him. Is that right? I saw the man myself, Stumpy. He looked so much like Bill that I didn't even bother questioning it. The only thing that was different was that he wasn't wearing a Ranger uniform. I've never heard of anyone who looked like Bill around these parts. I don't know how true it is, but they say that somewhere in the world, there's someone who looks just like you. I doubt whether that's true in every case, but it does play with your imagination. Well, it's certainly true in your case, Bill. I've seen the man myself. And right now, he's somewhere with Jojo. Right. And we've got to find him. You say that this is the exact place where you saw the man? That's right.  And you haven't any idea which way Jojo and this man went? No idea at all, Bill. I told you, after we talked with this man, I went into this store and did some shopping. Well, somebody might have seen him. What did Jojo have on? Of course. He had on that silly Sherlock Holmes hat. It's too big for him, and I think looks a bit ridiculous. Surely someone noticed it? Good. Now here's what we'll do. You and Stumpy start up in that direction, and I'll start in this one. We'll ask anyone who might have been here this morning. Possibly we'll be able to follow Jojo and find out what kind of situation he's gotten himself into. There, that should hold him. I have checked carefully all around the warehouse. From inside, of course. I do not think the young man brought anyone else to us. You didn't think you were followed at all, 16? This will not go well with us when we report back to them. I know. I know. At least we have the papers. Yes, that is true. What shall we do with this young intruder? Put him in the back room while I think of something. Come on. He does present us with a problem. I will puzzle it out as I microfilm these papers. I'd better retrieve them from the wastebasket. Yes. And I will set out to get our plane reservations. Take great care, 16. Too much has gone wrong already. Let's be sure nothing else interferes. I will do what I can, 13. I will go now to make our reservations. And I will try to decide exactly what to do with our curious little visitor who is tied in the back room. I'll never complain about that silly hat again. He sure is a good thing. He was wearing it. And I'll say, surprising how many people noticed him. It's been a much better trail than I'd anticipated. Oh, dear. I don't like the looks of this neighborhood. Are you sure this is the way they came? This is the direction everyone who saw him says he was going. Looks like we're getting close to the waterfront area. Not a warehouse is coming up. Have you noticed one thing, Bill? What's that, old timer? I think a single person has said he was with anyone. You'd think they'd mention it if he was with someone who looked like you. That's a good point, Stumpy. But why would he come down here of all places alone and not tell me where he was going? I'm afraid we'll have to ask Jojo that one when we find him. My. Aren't there a lot of these warehouses? How will we know where to look? Maybe this fella coming this way will know something. Ask him if he's seen Jojo, will you, Bill? Sure will. Excuse me, sir. We're trying to locate a young friend of ours who we think came into this area some time earlier today. We wonder if you've seen him. Not bad, Rudolph. Not bad at all. What was that? I don't think I made that out myself. Excuse me, sir. Maybe you didn't quite hear me. I heard you, Rudolph. I was complimenting you. This is one of the best yet. I think this fella probably won't be much help, Bill. Oh, Bill, is it? I guess it depends on the country, eh? Where'd you get the forest ranger uniform, Rudolph? Maybe we'd better start from the beginning. Maybe we'd better start for that car over there, all of you. If you come along peaceably, there won't be any trouble. If not, I and my friends in the car will have to, um, convince you to come. Hey, what's this all about? The name is Downes, FBI. Oh, dear. FBI? That's right. I don't know how you two are involved with this phony ranger here, but, uh, we'd all better go for a ride together. Phony? Now, hold on there, young whippersnapper. Bill Jefferson is no phony. As a matter of fact, how do we know that you're the real article? Let's go over to the car. Come on. Uh, just a minute. We do have the right to be satisfied as to your actually being an FBI agent. Over to the car. We don't want any trouble. I'll show you all the identification you want. Then maybe you can show me some papers we're interested in recovering. I sure am sorry, Mr. Jefferson, but you look exactly like that spy we're after. That's okay, Dean. And the name's Bill. Really? We know that now. It's a good thing Colonel Anders has his ranger headquarters here in Central City. You might have ended up in jail. I don't think so.  Can't get over how much you look like that spy. Hey, sure we'd like to lay eyes on that spy, fella. So would we all. Especially now that it looks like Jojo Jones has somehow got himself mixed up with him. Well, they must be around this area somewhere. Both your leads and our trailing Jojo have led us to this warehouse. The question is, where are they down here? In which warehouse? Look, look, there he is. Yes, sir. I can hardly believe my own peepers. That man who just came out of that there warehouse up ahead was you, Bill. Keep driving past. I'll hide my face so he doesn't see me. Remember that warehouse. You can drive around the block and catch him after he's far enough away that someone inside couldn't see him. Good idea. Did you see him, Bill?  That's remarkable. Gives me a funny feeling to see someone who looks so much like me. Now maybe you understand why I didn't believe you at first. You know that I am really not him and he means. He cut that out. You should just about be coming around this corner now. I'd better pull over. I'll get out and bring him over to the car. You all wait right here. Okay, sonny. Sure you don't need any help. I think he probably knows what he's doing, Stumpy. Besides, I think it might be a little safer here in the car. You've got the idea, Mrs. Jones. I don't expect any trouble, but you never know what a man will do when he's put on the spot. Bill, you might cover me from here. There's a gun in the glove compartment. Oh, dear. Okay, Dean. I hope I won't have to use it. So do I. See you. Here's that, Spy-Feller. I sure am glad you're sitting right here, Bill. I wouldn't be able to tell the difference if I couldn't see you the both of you at once. It's amazing, all right, old-timer? Looks like Dean isn't going to have any trouble at all. That's good. Here they come. That Spy-Feller doesn't look the happiest I've ever seen. Hey, I can see a difference in you, too, Bill.  Get in the back there with that other man. All right. I can hardly believe it. Even this close-up. I'm coming around to sit in front. Well, you have quite a reception committee. He even sounds like you, Bill. It's uncanny, isn't it? What is all this that you're talking about? Bill, um, turn around and show this guy who you are. All right. Good afternoon. Look at the look on his face. He looks like he's seen a ghost. He sure does. You'd think he'd never looked in a mirror before. Who would have thought that there would be someone that would look so much like me? Whoops, hold on there. If you weren't watching, there's no way of telling who's talking.  That's right. I am. That's exactly what we wanted to know.  I don't know who or what you're talking about. Is he harmed at all? What have you done with him? I guess he isn't talking. We've got to get into that warehouse and find out what's going on. Let's get back there. Not so fast. Who said that? I did, Bill. I have an idea. If they're planning to leave tonight and have those papers, they wouldn't just be relaxing. If we went in there, we might meet a pretty hot reception. What do you suggest, Bill? Why not let me change clothes with this fella and go in there myself? If you can't tell the difference, we can assume that his friend or friends can't either. You can radio for help and rush the warehouse if I'm in there too long. It'll never work. My friends are too smart for a trick like that. Besides, we know all about you. I doubt that very much. Sounds like he's arguing with himself. If you and your friends knew all about me, why did they assign you to a job so close to where I live? Too much danger of running into either friends of mine or myself, I'd think. Good thinking, Bill. Now, let's get these clothes exchanged. I'm anxious to get into that warehouse and see if Jojo is still all right. Just a few more and they'll be ready to go. Now what? The television viewer is still on. Let me see who breaks in upon us now. What?  Why has he come back? 16. 16, what are you doing back here? I, uh, I forgot something. It'll only take a minute. Well, hurry up up here. What if someone saw you? I don't think there's any danger of my being caught. There is danger, for both of us. And what do you mean coming in that way? You set off the alarm. I'm sorry. I, uh, I forgot my key.  I might have killed you. Come in quickly. Um, where are the others? Others? What are you talking about? What others? Are you all right? Of course. I meant, uh, the boy. Where's the boy? You know very well where the boy is.  Now get whatever it is you came back for and go for those reservations. We have very little time. Less than you know. This is no time for your morbid humor. What did you come back for anyway? To get the boy. What? That's right. Here you go, Jojo. What are you doing? Have you lost your senses? I'm releasing the boy. What does it look like I'm doing? But why? Stop it. Here you go, Jojo. Now the gang. I demand to know what you're doing. Why have you released the boy? I needed the rope. What are you going to do to me now? What did you need the rope for? There's plenty of rope around here. I needed this rope to tie you with, my friend. Bill, I'll see you. Is it really you, Bill? Why? That's right, Jojo. Are there any others around here? I don't think so. Just him and another guy who looks like you. Good. You won't take me. You won't take me. Stay put, Jojo. He's not going far. We'll see who isn't getting away. You got you. Run outside, will you, Jojo? There should be a few FBI men waiting to come in here and one mother very anxious to see you. Well, boys and girls, as you can see, sometimes it isn't easy to tell the real thing just by looking. You can see why the Bible tells us the Lord sees not as man sees, for man looks on the outward appearance, but the Lord looks on the heart. It's there that what a man really is, is seen. Well, see you next week for more adventure with... Ranger Bill was produced in the radio studios of the Moody Bible Institute in Chicago.
