Okay, very good morning to everyone. I hope you're well Thursday 29th of August Going to of course review what happened last night Seemingly whenever I'm off the desk. It's when all the fun stuff happens. Some things ever change But obviously the fairly sizable move in the pound yesterday, and it's moving to the downside again this morning still got another I'd say What 25 30 pips or so till we get to the extremity of the low point from yesterday? But we can have a little bit of a catch-up of what exactly happened and what are the thoughts going forward? And then one of the other big talking points from a news perspective is that in regards to Italy? We've seen Italian 10-year yields move to record lows We'll look at the reasons why and what my thoughts are on that going forward Not going to dwell too much on the charts. I'll leave that to Sam but to give you an overall flavor of just general Market sentiment at the open I wouldn't say it's overtly one way or the other if anything mild risk off Equity index futures US and Europe marginally lower. However The S&P's kind of been clawing back any late losses that were seen Towards the early part of the Asian session But the 10-year touch higher up 7 ticks gold up $7 at the moment The Dixie is trading up just shy of one tenth. So a little bit of downside pressure Let's say cable Worth keeping an arm for the aforementioned reasons about the latest news from yesterday So let's get straight into it. What are we looking at? And this is the kind of latest response behind the surprising move from Boris Johnson yesterday to suspend Parliament now the overall thinking here being a push to basically give MPs lesser time to block his Kind of pursuit of the threat being credible of having a no-deal Brexit on October 31st Now a couple points to cover here in theory Suspending Parliament is a fairly normal event However, the timing is of course particularly suspect given this very short timeline We've got until what could be a very severe economic situation if we have a no-deal no-transition disorderly Brexit so prorogation as it's called the shutting of a kind of parliamentary session or term Which is then kind of bookmarked and by the Queen giving her her go-ahead Now the Queen doesn't really have much of a say in this process It is really purely symbolic and what would normally happen and it has done for the last hundred years in our history Is that she goes off the The advice of the Prime Minister of what should happen the fact that Boris Johnson has gone to her and requested this is Essentially, then she just gives it the rubber stamp very rare if ever has happened as I said It's been basically a non-event for the last hundred years Shows how unprecedented this Brexit situation is that the Queen would ever consider getting involved on this kind of political level So not unsurprising that the Queen has backed that Then what does this mean going forward? Again the timing is key what's again more Controversial of course is the length of time involved because we're talking about a five week process Which means the MPs return from recess next Tuesday, so let me just flat flash over to a different graphic MPs return for recess next Tuesday And they will only sit for around a week before and Parliament closes down again until mid-October So this graphic is slightly chopped on the right-hand side here. So let me just see if I can Shrink it. There you go. So you got Parliament in session on this timeline Chronological from left to right going from now to the future Parliament in session is in orange So they come back in a few days time They then would technically break up and Parliament is suspended only then to come back for recess or from the recess and just in time for the Queen's speech again So as much as the Queen is The figure to end that session she then gives a speech to reopen the new Legislation under the government, which is what Boris wants. This then gives a very short turnaround into the European Council meeting Boris's strategy I think as we'll discuss I think is still to Secure a deal, but I also think that that obviously needs to come with an extension and then a general election So I don't think that and the reason why the pound isn't through the floor that this is just right The odds are on now for a no deal. I'd say they've gone up But I still don't think that that is the at least still at this point the end outcome of the situation And we'll discuss why in a second the other thing is What would normally happen is Parliament is suspended anyway in late September early October Why does that happen? That's because every year you have the Labour Party conference the end of September and you have the conservative one that follows a few days after So actually technically speaking although he's pushed this It only adds I think technically three more days to what otherwise would have been a suspension for the for the party conferences period anyway but obviously it's being dressed up and a lot in the press and What or who is going to be a very influential figure on this because he can use and adopt his discretion Is the house speaker burko, of course Of which has been an ardent kind of backer of having Parliament have it say very much remain Minded think he was quoted yesterday as saying it's a Constitutional outrage and and so on so I'm sure there's got a look gonna be a lot more twists in this story Before we get to the end point now the main implication of what's happened Basically in the last 24 hours as it will make the legislative path to blocking a no-deal Brexit more difficult But importantly not impossible So very important that last point if though the legislative attempts fail Opposition MPs are left with little choice But to back a motion of no confidence if they want to stop a no-deal Brexit now what that means No hang about she's got some new comments Just come down to news wires China's Commerce Ministry asked about trade dispute with the US says both trade teams have been in touch That's just come out stocks rallying So let me just put my Brexit discussion on ice for a moment Media upside just going through the equity space S&P just powering through The late Wall Street highs Bund and T note futures backing off gold seeing some downside. So just to repeat the Chinese Commerce Ministry has just come out US are in effective contact China will not crack down on foreign companies, but China think should discuss removing the new tariffs So remember we've had a complete almost catastrophic breakdown giving the Trump flip-flop we had at the last week We have had overnight. Let me just quickly jump over to this You've had Manichin says China trade meeting will happen But won't say when but now a very positive update coming out of China who looked like they were being much more aggressive So you can see the reaction and sensitivity in markets to this headline Stocks just motoring on the back of that last piece of news currently markets the least Reactive yields gold stocks definitely buying into that headline So typically this is what you see where the fast money moving in markets the speculators jump in you can see in the center for go back to the The charts here you can see here in the center chart Nasdaq and to the right of that the S&P 500 futures Immediately then markets typically use these daily pivot levels as very near-term and clear Targets to run the price to in the kind of momentum-based trade In the initial reaction and then you can see quite Substantial pullbacks then set in as people just bail on that trade looking to book profit and maximize on that short-term volatility But definitely an interesting development there and obviously just fresh off the press just coming right now But quickly jumping back to Brexit obviously things are in flux. So I'll try to keep this as brief Concise as possible It's going back to this chart As I said then if legislative attempts fail which timing as a de essence and you would say potentially they're running out of time Then opposition MPs are left with little choice But to back a motion of no confidence if they want to stop a no-deal Brexit now This obviously starts to lead down the route of a potential then General election now I've read absolutely fantastic comment that I think really Summarizes what I feel is Boris Johnson strategy here from the chaps at ING who who made this graphic They said an election that is forced upon the government of which in this case as we're discussing would be and Coupled with a further Brexit delay because to hold a general election would require more time to basically set up the process So you'd have to delay Brexit would allow Boris Johnson to campaign on a tough Brexit stance Without risking the economic impact of a pre-election no deal This would be then I think Boris Johnson's move that he's done The more I think about it the more I think it's a stroke of genius Because actually what it means is that you're allowing less time. Yes What is going to happen is you're going to have constitutional? Kind of pushes where the legal courts will try to come in this has already happened yesterday Gina Miller and others have tried to table an urgent injunction Over Boris's ability to be able to do what he's done. The point being is though It's almost unheard of in the history of Britain for the for the Queen to come back for Boris to Go actually I was wrong. We're gonna. I'm gonna go back to see the Queen. I'm gonna reopen Parliament That's not gonna happen. So the point being these legal challenges. I think are fairly hopeless so if we go down this option of What's gonna happen is in the vote of no confidence leading to a general election just imagine the amount of support Boris Johnson will have by people who want the delivery of Brexit he now has been blocked by Parliament the Ramoners if you like If you're of that political stance He's failed to deliver and what he's been pursuing is the democratic will of the people blocked by Parliament This is only gonna fire up even more sentiment to back him and he averts then the worst economic situation Of not having a no deal. He gets a big majority in Parliament then on a new election He then goes to Brussels and then secures a deal and actually there you go There's no no deal. I still don't I still don't think that's gonna happen He then gets a deal over the line, which I still still think is the best Outcome for what the government even under Boris Johnson wants. He doesn't want to be the in the Premiership seat Given a dramatic economic Recession that we would head into So also not forgetting I think to further support this argument of what I believe is gonna play out Is the fact that Boris Johnson remember only a few days ago said? There's no way I would speak to Europe without them I would never even have a conversation with Europe without them dropping the terms on the backstop and there He was at the G7 Rubbing palms smiling joking and so on so I definitely think that there's more Strategy behind perhaps what looks like a an impulsive move perhaps to be interpreted that way I definitely think that this is actually quite a bold but quite a savvy one that he's made The one thing that this does mean if you're trading the pound. This is a picture of the pound dollar three month implied volatility and We're looking at levels that we haven't seen since the peak of really Q4 of 2018 and so the point being is you're gonna see much more Possible violent swings in the pound coming now obviously the downside level We've seen a pretty decent bounce in recent weeks off that 120 lower bound We're about two points above there at the moment but for sure I would say between now and October 31st and This is the timeline you need to be aware of so do check that out. I did share it on our amplify Twitter account There's gonna be loads more headlines to digest because even though I've talked about the end game of how I think this will play out and If we did get that extension and the general election if anything I think there's gonna be periods of relief followed by Stress and panic before that even happens because the increased risk has to be priced in for no deal So you're gonna see big swings in price action Importantly no one's going to be really wanting to sit in any type of medium long-term position So the people trading the market will be the speculators and momentum Chasers following these spikes in price movement, which almost exacerbates it So definitely you need to be quite agile and flexible to trade that product if you're gonna be looking at it All right enough of Brexit. Let's move on the other thing I wanted to talk about was Italy Because the Italian opposition PD and five-star say they want to form a coalition led by Conte now Tommaso amplifies Tommaso, which you know, well He wrote an excellent summary of what has been happening in Italy and I'll read it out to you He said the reshuffle will avoid an early call to the ballot boxes in October Remove concerns over the 2020 EU budget submission and avoid the increase of the VAT in September Moreover, the exclusion of the widely announced flat tax from Salvini and the citizenship income from the five-star as part of the previous government mandate Releases investors by their worries on the costly implications of these measures on the Italian fiscal budget net net Europe happy again, and so what has happened here is this The Italian 10-year bond yield This hit a record low now You remember I was sharing your graphics about this quite monumental rise the spread widening between the BTP boom spread as Italian yields were rocketing Given the uncertainty that was triggered a few weeks ago by the breakup of the existing coalition when Salvini Port the trigger on that kind of clerk collaboration if you like and that brought about the risk of new elections the risk of the league getting into power and so on that now has dissipated Fantastically and so yields have dropped dramatically and let me just bring in to shot here What that looks like on a chart and I'm going to show you the BTP future So we're looking at the yield This is the price as you can see here quite It's been quite a technical product to trade actually you've had that area of really a double top Which has defined some of the price action of July and the early part of August you then came back for a nice little test Here as sorry, let me just remove that box there nice test for coming back as what was resistance to then support On the 22nd so about a week ago before then a real breakout on the upside as things have got more positive Towards and again resistance support on the pullback and in a really aggressive push higher, but check out BTPs on the long term This is the weekly now that we've rallied very aggressively in the yields fall into these record levels I would say we've come into a fairly significant obstacle on the upside. It's looking at BTPs here This is a weekly Continuation chart you can see this is the high of 2016 we pretty much come bang up there to the tick So I'd say for now That is the the limitation of that move as I see it for the moment So if you had a part if you got hold of it over the last couple of days particularly yesterday Exceptionally large moved and well done. I think now you've kind of seen the end game for that One thing actually that I did tweet and just to give you what my end assessment is of what this means going forward Was this? If I quickly switch over Personally, I think this Italian bond yield move we've had in recent days is overdone My reason in being I think a five-star PD combination Still isn't yet a complete done deal They still need to appoint the various different people if Conti who's more Favorable and leaning towards the five-star that would mean you need to have a deputy from the PD of which no one yet Has been announced as well as other senior appointments So there's still lots to be done but underpinning everything Even if they can get and obviously the move that's happened in Italian assets is if anything I'd classify as a relief that the worst case under Salvini is not materialized the problem I have is to fight star on the PD I mean the only thing in common that they have as political parties and agendas is the fact that they hate the league That is no basis to form a coherent long-lasting and effective relationship in my opinion So now that this relief has happened I ultimately do think that even if they do come together and able to form a Relationship of some substance. I do think that it's a fractious relationship that will come undone in time And we will arrive In due course back at where we are right now with Italy and I do not think that that relationship will last particularly long Whether one year whether two years It's a stop clock. I would say in my opinion All right other than that I'm actually gonna just wrap up the calendar and then hands you to Sam because we've talked for long enough We've had a couple of the German state CPI is coming out this morning Saxony's already been released about half an hour ago The month-to-month minus zero point two percent previous was plus point four your near decreases by point two to one point four percent So a bit of a pullback there I'd say unsurprisingly though in the first German state CPI will get the others to follow Otherwise for the morning What else have we got it's pretty quiet again the biggest development actually from a news perspective this morning is the Chinese comment and It's a positive tone that's been struck Otherwise it looked like almost China had washed their hands with doing any dealing with Trump But seemingly they're looking to come back to the table and that's being translated into positive stocks unwinding of that risk premium pullback and T notes and gold for the rest of the session Focusing predominantly on the US you've got the second reading of US GDP looking for it to be relatively unaltered As two percent print against the advanced reading of two point one that will course come alongside things like core PC prices You also get the advanced goods trade balance number and a weekly jobless claims And then that's about it for the moment So given what China has said I do think a new element to add to your calendar and your awareness to any trades is You've got to wait till Donald Trump wakes up. What does he say and I think Personally, he's gonna come back and say something fairly fairly Concillatory let's say towards he'll like these comments from China. He'll say yep Let's get a deal done because he wants to just reinstill a little bit of positivity back into the market So look out for those Trump tweets Of course, he tends to have a pattern of waking up and tweeting from a London time from around 11 I'd say about 11 a.m. You should really start being prudent for any tweets that he that he does But typically they come around 11 30 11 40 the first ones, but given the context He definitely will be saying something on trade, you know in a couple of hours time All right, how'd you have the Sam and I wish you a good day. Thanks very much guys Hi guys, good morning Yeah, let's have a quick look at equities those comments obviously helping pushing price higher there across the board not just in the U.S. But Europe as well as always always worth keeping just a And ear to the ground on the reversal of these comments that didn't die on from the other side And now we are just in a bit of a pullback I guess if you were looking for this continuation and certainly u.s. Equities You've got to take that 29 a hundred where we're trading now the the hide that we had back on The 27 which would be Tuesday just a pretty key area in general So definitely worth keeping a close watch on here and you can also see the from this morning And you know the the break above this trend as well That's along with the previous higher the mornings is not very you keep an eye on so a couple of key points Just below where we're trading most notably now yesterday's high let me just make this a bit bigger for you and Obviously the trend line and high of the day break which came on that story That just came through While Anthony was was running through that briefing above where we're trading obviously we had a big spike to that higher the day and you can see You know the really key resistance zone and to me what is is stopping any push to all-time high We have to get above This area here those highs that we had back on from the 8th The 13th and then obviously struggling to get there the back end of last week before Friday's Trump meltdown that we saw so key level now, but obviously for the main part of the week It really has to get up there and just to go over again The it's just clear this up The the image of of how we're trading now you can just see how similar albeit squeezed down This price action is compared to The one that we had October November December last time so certainly medium term trade wise I was keeping an eye on that top end of that range and I do like the idea of a long above there However, I just don't think that's going to materialize as of as of yet quick look over in Currency spaces and said no real reaction from there the pattern Euro Yes, they really start into break what did start to break that mini range of the low Yes, then it's worked as a good resistance. It's a very small Range that we're now in but definitely worth having on one eleven pretty much to the tick as your top end now And yesterday's lows coming in at one ten ninety So small range there in the Eurokeeper and a watch on what happens at both those extremities a break of that Considering how small that range has been Whether you could get a big push down to the low that we had on the 23rd or not will remain to be seen You know, we're worth worth seeing what happens there trend line wise. You can see yesterday We we did have one but not as well respected. So I had this on Earlier in the day yesterday I mean actually I'd still have it I'd still have it's failure to really close above that Maybe it's a bit of a guide, but you can see today anyway the 111 handle on the futures just above the pivot remains pretty key as does obviously Yesterday's higher point as well, which came on the pivot with the pound with headlines yesterday It's starting to get into that that moment where You know, we've had the pound not necessarily comes untradable, but you just really need to be careful just in the last week Obviously got those Merkel comments. You've got the the Parliament Suspending oh, yeah, I'm not even an attempt to say that word What ants need to set and you can see we came love so you've got to be careful certainly trade in the The pound for now So yesterday's lows as I said not too far away from from where we're trading worth. I guess, you know, whenever there's Couple of lows in the mix starting to to get trend lines on what potential trend lines on shall we say so that low that we Had back on the 20th to yesterday's low That's could be a potential point just to consider if you get a bit of support on That trend line well later on in the day or week the opportunity to get short on the breaker That is is always not a not a bad idea as you can see probably worth having on a trend from the last couple of highs As well certainly on the 30-minute chart waiting for a break either way should it be respected gold and T-notes came down off those headlines Understandably so worth again to sort of keeping a close on where those lines in the sand may be and with gold You can see as well similar to those other markets just starting to trend or this morning It's just starting to be trending higher so work having that trend line on and I need a break with that is a break of the Certainly the intraday trend shall we say so that's something I would would have marked up and as we get higher As I say we get lower below there. You can see a really well-respected trend from this week so far We've got those free tests already So we know the market is looking at that and maybe even by the time it comes to it It's in line with the lower the day at the moment or even the pivot So certainly one to have an eye on going forward there above the the level we're trading You can see the high was that point we've talked about from the 26th Asian session And if it was to get above there cleanly Well, you get the that high that we had from last week as well silver. We talked about yesterday Keep as it is keep on on pushing on and on and as I mentioned a couple of my friends are in this trade And they're very happy to see we or they I should say reach one of their targets Which was that high that we had back from January 2018 Bit of resistance found there before breaking through again today It's on really is on a tear and you can see this move really starting once we had broken out this pattern here Really good opportunity back on the 23rd and it has not looked back since Have a quick look over at oil here just to finish things up. We can still see this line may well have been on from Yesterday certainly an important one today. You could argue. It's a bit more of a zone around the S1 of 55 27 Yesterday's low the high that we had back on the 26th as well and a bit of a lower point from yesterday really key zone if you like of Support below there to ensure it can start to drift down to the upside pivot 56 some nice price action as Resistance there last night as well. I got that mini range if you like so above 56 You know really be looking for a push maybe to the upside If it can get strongly above 56 20 if it goes below s1 Then I'll be looking for a drift lower to towards 54 83 and then the s2 as the next sort of target So some interesting points in oil also, I guess going into this morning It'll just be a case of whether we can get a continuation of this move That 2900 as you see the first real level support below has acted well and we've had a Four four and a bit point bounce from there. So decent enough So far obviously just be careful of the opposite comments coming through In that in this market any questions as usual. Obviously, please, please do let us know To be on the mic throughout the day, but I hope you will have a good session ahead


And in this talk, what we try to do is to revisit and to give a new vision to a property, a distinguishing property that was introduced last year by Yusuf Ketodo in Europe in 2015 and that's called the division property. So the general setting, so we're interested in work ciphers, and a particular analysis of book ciphers. So in general, when an attacker wants to break a cipher, the first thing that he will try to do is to find a distinguishing property that should hold for every value of the secret key key. Okay, once this distinguishing property is found, he can probably try to mount a key recovery attack to find the value of the secret key or part of it. But in this talk, we'll only be interested in this distinguishing, in how to find a distinguishing property for our block site. So last year, Yusuf Ketodo presented, introduced a new distinguishing property that he called the division property and in some way this can be seen as a generalization of integral and higher order differential distinguishes. So he managed in particular by using this to break, to fully break full misty one for the first time and this was the best paper award at last year of crypto. So I will try to explain a little bit what is a division property, but before this, I will introduce the notation that I will need. So the first notation is the way I will represent monomials of n variables. So imagine you have two vectors, two n-bit vectors, x and y. I will denote y, x to the power of y. The product coordinate by coordinate of xi to the power ui, where xi and ui are the coordinates of the vectors x and y. So let's see this with an example. Imagine you have the u is the vector 1010. So x to the power of u will be, so the coordinate x4 to the power of 1, the coordinate x3 to the power of 0, the coordinate x2 to the power of 1 and the coordinate x1 to the power of 0. When we have a coordinate to the power of 0, actually this always will give 1, so we don't care about dispositions. So this will give the monomial x4, x2. Then imagine we want to evaluate this monomial. So at the point, let's say x equals to 1100 and what we will get is so we compute 1 to the power of 1, 1 to the power of 0 times 0 to the power of 1 times 0 to the power of 0. And actually this product always, almost always gives 1. Only, we have 0, only in the case when the base is 0 and the exponent is 1. So what we can say is that from this, if we evaluate a monomial, we say that it will be 1. If and only if we avoid the situation where we have 0 in the basis and x1 to 1, which means that we have, the sum will be, the product will be equal to 1. If and only if all the coordinates of U are strictly smaller or equal to the corresponding coordinates of x. And this is, so this is the partial order and so when I will say U is smaller or equal to x, I will use this, I will mean in this sense and I will use this special notation. Okay, so what is the division property? Actually, if we have a set of elements in order to the n, we will say that the set x has the division property of order k and we will denote it by dnk. If the sum, when we take the sum over all elements in x of x to the U, so of these monomials, is 0 for all vectors U that have a humming weight that is strictly less than k. So if this happens, we say that our set has a division property of order k. So the division property is a kind of generalization of integral properties because for some particular values of k, we get some very well-known integral properties. For example, it is needed to see that when we have k is equal to 2, if a set has a division property of order 2, then actually it has the balance property and when it has a division property of maximal order, then it has saturated property. That means that all the values in the sets are taken exactly once. However, the novelty in the division property is the introduction of these intermediate properties, that means properties for ks that are between 3 and n minus 1. So there is not a very nice, we don't have as an interpretation of these intermediate properties. However, we can propagate them and get some information and use some information about the algebraic degree so to construct distinguishes. So this will be the outline of my talk. I will start by introducing the main notion of this paper, that is the parity set of a set. I will show how this is linked to the division property and how we can use it to get a very nice description and easy description about sets having the division property actually of any order. Then I will show how we can use this property to construct distinguishes for iterated block ciphers based on the SPN construction and finally I will show an application with some low-data distinguisher on the lightweight block cycle present. Okay, so what is a parity set of a set? So the notion is very easy. Actually it is exactly the set that is composed of all exponents u such that the sum, I want to take the sum over all elements x of the monomals x to borrow u is 1. So actually this sum can be 0 or 1 so you put in the set all the exponents that make the sum is 1 and this will be the parity set of x. Okay, so what is nice? First thing is that you can compute the parity set of a set very easily. So to do so I will need a notion of the incidence vector of a set. So the incidence vector of a set of x to the n is just a binary vector of 2 to the n that has 1 at all the positions for which x is in the set. So let's see this with an example. For example, let's say n is equal to 3 and the set x is composed of 3 elements 1, 4 and 7, then the incidence vector will be a vector of length 8 of coming way 3 that will have once exactly the positions were corresponding to the elements in the set. Consider now a binary matrix with 2 to the n rows and 2 to the n columns where the coefficient of intersection of row u and column a will be the evaluation of the monomial a to the u. Okay, and what we can actually show quite easily by just taking the different affiliations right on them down is that if you want to obtain the incidence vector of the parity set of a set you actually just take the incidence vector of a set and you multiply it by this matrix g. For this example, so here n is equal to 3 and here is the matrix g corresponding to this n so the columns are fixed so the column corresponds to the basis and the rows correspond to the exponent so if you do this computation you obtain this binary matrix that is upper triangular and let's say your set x is 1, 2 and 4 at 3 and 4 you compute the incidence vector you multiply them and what you obtain will be the incidence vectors of the parity set corresponding parity set. So finding the parity set of a set is actually very easy and what is nice about this what we will see is that actually the parity set of a set is unique so there is one-to-one correspondence between a set and a parity set and for this I will need the notion of of read-mular code so a read-mular code of length 2 to the n and order r is just the set of all value vectors of all Boolean functions that have degree that is less or equal to r and if you look if you are a little familiar with read-mular code and you look at this matrix actually you will immediately see that this matrix is a generational matrix of read-mular code of length 2 to the n and order n and so what is nice about this is that we know that this matrix has full run that's invertible and that is inverse it's the matrix itself so it's involutive and exactly from this what we see now because of this we have an esomorphism of binary vectors that matches the incidence vector of a set to the incidence vector of the parity set so which proves that for each subset u there is a unique x such that u is a parity set of x and you can go backwards so there is a 1-1-2-1 correspondence so what is now the link of this parity set and the division properties so actually it's easy to see that if you have a set x that fulfills the division property of product k this just means that the parity set all the elements in the parity set will have a height and weight that will be greater or equal to k which means that the division property for product k is just a lower bound on the weight of the elements in the parity set so here what we will try to do so instead we'll see after to propagate just the division property so this element k and to see how it downgrades through the wealth we will try to propagate actually the elements in the parity sets and this will be nice and we'll have a more accurate actually representation and we'll have the form of the elements we'll better see what happens okay for the moment let's stay for in the more theoretical part so actually what we can buy this link and by using rhythm law course I will not get into details but what we can prove is that if you have a set x that fulfills the division property of product k and this is the true if and only if it's incident specter belongs to the rhythm law code of length to the n minus k and order n okay and this correspondence permits us to show actually things about what does it mean for a set x to have a division property of a certain order this was a question that last year many people tried to answer so therefore some extreme cases for one, two and n the answer was given but very often in a very complicated way but if we take the correspondence with the rhythm law code we can actually give some proofs just in one or two lines so for example it was proven by son and our last year that if it's x fulfills the division property of product k then what we say about the set x of product k elements this is the result the proof was very long but with rhythm law codes we can prove this in one line just using the minimum distance of this code and what we get more is that we know when the quality happens it happens exactly for sets that are as fine subspace of dimension exactly k okay so we can recover easily results that were already known what is new is that we know we can describe exactly all sets that fulfill division property of order m minus 1 we say that we know that they're exactly all the final hyperplanes okay so now we will see how we can use this property, how we can propagate it through the round operations of a substitution permutation network in particular we will see what happens with the party set when we go through key addition and when we go through sbox okay so the first operation usually in SPN Cypher is the addition with an unknown key so unfortunately as the key is unknown we cannot we don't know exactly what happens with the party set after the addition but what we can prove is that the elements that will be in the party set after the addition will be all the successes of the elements that were there before so with an example let's say n is equal to 4 and the party set of x is composed of 2 elements 3 and c and now we are the same secret key to all the elements in the set we don't know exactly what will be the value but we know that the party set will be included in all the successes of 3 and c that gives this the following 7 elements so let's see now what happens when we go through an sbox so we would like to so we have in the beginning a party set then we apply an sbox to all the elements of the set and we want to see what is the party set at the output of the party set so if you use a definition if you want to find which are the elements v that are in the party set of after the sbox the definition says that there will be all the elements p such that when you take the sum of s to the power of v this sum is equal to 1 which just means that the algebraic normal form of this function that is just the product of some output coordinate of the sbox contains some x to the power of u for some u that belongs to the party set and why this is so because if it was not the case then the sum would be 0 so now I will define the set v as u that will be exactly all the vectors v such that s to the v that is just the product of some coordinates designated by v will contain the monomial x to the u and now we can see that the party set so after the sbox will be the union it will take all the elements in the party set of x of this set v as u and this set will contain the formal matrix and it is very very important actually for the resistance of the cipher against this type of distinguishes so here is the matrix v as u for the sbox of the block cipher present so what we see here so the columns they correspond to the products of output coordinates so what does it mean so we have here and correspondence directly with the algebraic normal form of a function so here you have the four coordinates the algebraic normal form of four coordinates of present and actually what you see if you look at the first four columns what you have vertically is just the algebraic normal form of each coordinate because for example if you have the x at the intersection of the row 4 and the column 1 just means that the monomial x x4 belongs to the first coordinate so there is also of course we can also compute the this set v as u not only from the sbox system but also from the inverses box I will not explain this into detail but actually as the cipher mutation we can easily go from one to another and probably we won't have to explain this but what we can see that so columns correspond to the algebraic normal form of the sbox and two rows so if we see rows they correspond to the algebraic normal form a kind of algebraic normal form of the inverse sbox so ideally we want that this this matrix is as cool as possible we don't want to have sparse lines or columns so to see this I will show an application to a block cipher present so the only things I need from this design is the fact that it has 64 bits of block size that there are 16 sboxes of 4 bits of degree that are applied in parallel and that the linear layer is a bit permutation so Yosuke Toto in his seminal paper he describes some generic distinguishes based on the division property that only exploited actually the degree of the function and not any other any other properties so if we fix the input size so the data complex of the distinguisher to do to the 12 he managed to find a distinguisher for three rounds present so what I will show here that is that the bus taken into account the linear layer and the sbox we can find distinguisher for four, five and six rounds by keeping the same data complexity so for doing so we will start with the input set X we will have the following form so it will be of size to do the 12 where we have three nibbles that take all possible values and the other nibbles will be fixed to a constant value so we can see from there that the part is set actually just after we have the key addition we don't know what will be the value so for the parts when we have the constant value the values of the part we don't think but us in the three nibbles we have the all property we know that there is only one element in the party set that is the all one vector so we know that the form of the party set after the key addition will be like here and this is concerted of the first sbox layer then we can now take into advantage the linear layer of present because we know exactly which is its form so we now just previewed the elements in the party set and then actually we can just use some, well we know what happens with the degree so we know which kinds of monomials we can have so we had gone with the details but it's very easy, we can prove that after four rounds we only have elements that have any way strictly great or equal to two and that means that our set has a balanced property so if we have an element that is equal to one then we stop the distinguisher we cannot say anything anymore we would like to move to five rounds but however as we can see this is not possible for all type of sboxes because we have found a propagation of the party of the values in the party set that leads to after the fifth round to an element of timing weight one but this is possible so this propagation is possible if the sbox makes the transitions from the elements e to one and e to two possible so we will see what happens for the present sbox so if we look at the line that is a row corresponds to e we saw that this row is very sparse and in particular there are no transitions to elements of timing weight one and only one transition to an element of timing weight two so this is a weakness of this sbox so we use it and indeed we were able to verify the computer programming that there were no elements of timing weight one after five rounds so that means that the output set after five rounds has a balanced property if we want to move more actually we cannot have a distinguisher like this for six rounds because there are elements of timing weight one after six rounds however if we look at the column now of this matrix we see that the first column is very sparse because actually the first coordinate of the a and f of the algebraic normal form of the present is only quadratic and has very few terms so what you manage to see is that there are after six rounds elements of timing weight one but not awful the elements are possible in particular elements that are correspond to the first coordinate of each of the 16 sboxes never appear that means that we have 16 values that are never appear so this gives a kind of weaker distinguisher so to conclude about this part the present sbox is probably not the best for this type of distinguisher that's why we had we were able to find this attack so if you want that your sbox design resists to this kind of attack the best way is to choose sboxes that have all of the components of the sbox are of maximum degree so now then we can prove that you will not able to have this sparse rows and columns so to conclude so we saw that the notion of memory is that it actually to capture more information during the propagation compared to the division property and so there are some open questions about this so the drawback is of course that it takes more time and memory to do the propagation because actually you have a lot of information to propagate when compared to just the timing weight that you have with the division property how to make this more time and memory efficient probably don't have any time anymore so I will stop here thank you very much for your attention


Welcome back to Gamedev Academy. I'm Shane and I want to ask you a question.  Well, if that's the case, then maybe, like me, you haven't been using the correct tool for the job. In today's video, which is sponsored by NVIDIA and SCAN computers, I'm going to be using an NVIDIA Studio laptop to see just how much the RTX 2080 can speed up my workflow by accelerating Arnold rendering. In order to put the NVIDIA Studio platform to the test, NVIDIA have lent me an Acer Concept D7 laptop, which is expect to meet the strict requirements of the NVIDIA Studio platform. I render a scene on both my PC and the Acer laptop to see just how using the right tool for the job can reduce render times compared to using, let's say, a less specialised tool. So let's start with using Arnold to render a relatively simple scene on my current PC setup. The important specifications for this are listed on screen. This scene is something I've put together for a new Maya 2020 tutorial that I've recently finished writing. Hit the thumbs up button if you want to see that tutorial sooner rather than later. So here's the scene and I'm going to render it with Arnold using the CPU. There are two ways that I'm going to measure the performance for this. The first, which is nice and straightforward, is the overall render time. The second, though, is the one that will make the most difference to my personal workflow with Arnold. And that's the time it takes the IPR, or Interactive Photorealistic Rendering, to get to a stage that I can visualise changes I'm making with confidence. So we're starting with rendering the image to see how long it takes. And as you can see, on this PC, it takes quite a long time to complete the render. Next, we'll take a look at how long it takes for the IPR to reflect changes I've made to a level where the image isn't so noisy that I can't be confident in the results. So I'll just change the camera angle for this and see how long the Arnold IPR takes to give me an image of a reasonable quality. And as you can see, this also takes a long time. Too long, really. Now let's jump onto the concept D7. Here you can see I have exactly the same scene, so let's see how long it takes to render on the i7-9750H CPU. As you can see from the render time here, this laptop is already doing much better than my crappy desktop. But there's more. One of the strengths of the NVIDIA Studio laptops is the accelerated ray tracing rendering which makes use of the RTX GPU. So let's render this again, but this time using the RTX 2080 and see if we can get that render time down any further. As you can see, enabling rendering on the GPU is as easy as selecting the option in the Arnold render settings and the result we get is a further reduction in that render time. Also, take a look at just how quickly we now get to a good quality image using IPR. For me, the improvement I'm seeing in rendering performance is night and day, so already I'm completely sold on the performance gains offered by the NVIDIA Studio platform, but there is one more trick up the sleeve of this laptop to push the rendering performance even further. That's through the use of the AID Noiser which makes use of the tensor cores on the RTX 2080. Check this out. I'm now going to change the camera angle again and look at how quickly the GPU rendering combined with the Optics AID Noiser gets the image to a point where I can feel completely confident in any changes I've made to the lighting or materials or framing in a matter of seconds. When I first tried this out, it actually blew my mind a little bit. I mean, look at how fast this is compared to the trash that I have been working with. It's ridiculous, but in a good way. Next, let's take a look at this rather handsome looking chap. This scene was sent to me as a good way to demo the rendering benefits of using an RTX Studio laptop. So we'll start with rendering this on my PC and then work through the different configurations on the Concept D7 to see the rendering gains again. So whilst I'm demonstrating this field, let's talk about what the NVIDIA Studio platform actually is. NVIDIA Studio is a technology platform for creatives that incorporates RTX GPUs as well as the NVIDIA Studio stack of specialised SDKs and dedicated NVIDIA Studio drivers to deliver the ultimate performance and reliability demanded by online and studio-based digital creatives working against tight deadlines to deliver high quality content. RTX Studio is a badge that's tied to specific laptop and desktop products that meet a set of carefully selected hardware and software specifications. The hardware and software components are subjected to thorough lab-based performance and compatibility testing against top creative applications and workflows. By choosing GeForce RTX Studio or Quadro RTX Studio branded products, creators will easily be able to identify laptops and desktops with the best out-of-box creative experience. As you've seen, Studio accelerates the ray tracing renderer Arnold by utilising the RTX GPUs. By combining fast RTX accelerated rendering with support for GPU accelerated AID noising, this means CG artists can work interactively with their models and scenes, quickly iterating through changes in materials, lighting, camera position and environments. Artists can view the effects of their changes with lightning fast updates in the Arnold render view output window. So I think this demonstrates the benefits of using the right tools for the job and when it comes to rendering, these NVIDIA Studio laptops are clearly the right tools for the job. I've focused on using the Arnold renderer for this video, but there are also some other really cool benefits for me offered by this platform, both of which I used when making this video. The first one was the use of the new NVENC encoder in OBS, which I used to capture the video from the Concept D7 laptop and also the hugely improved performance in Premiere Pro, which I used to edit my videos. Another huge benefit is the fact that all of this power has been packed into a laptop, and one that is much thinner and lighter and way more powerful than my own current laptop. So, do I recommend this laptop and the NVIDIA Studio laptops in general? Well, yes I do. I think the performance speaks for itself and working on the laptop whilst making this video has completely ruined the way I feel about my own PC. I mean, how can I go back to using my PC now that I've seen the light? The answer is I can't, hence the glowing box behind me. If you want to check out the Studio laptops for yourself, I'll leave a link to this specific laptop as well as some other NVIDIA Studio laptops offered by Scan Computers in the description below.  So I hope you found this video useful, especially if you're looking for an upgrade, and I'd like to thank NVIDIA and Scan Computers for sending me a laptop to play with. And finally, I'd like to thank you for watching, and I hope to see you again in the next video.


We have all the original plans, you know, the actual layout of where all the plans were put. So the gardeners today are able to sort of stand on the shoulders of the gardeners who did work here in the past. That's Down the Garden Path, a new series Wednesday nights on Highland Radio, after the news at 8pm. Classic Tracks with Jean Curran. And welcome back, and in the studio with me now I have Anne-Rie Faulkner, and she is a translator and writer, and has translated a book from French into English called Each Day is a Farewell. Anne-Rie, you are very welcome. Thank you very much. So tell us a little bit about yourself, you're from Donegal anyway. Yes, I'm from Moville, and I went to school in Cardona Community School like most people do. And it was there that I first started to study French. So you have a degree, a BA in French Studies from the University of London and the Sir Bonin Paris, and then you've got a master's in translation from Queen's University of Belfast, and three languages that you translate, French, Spanish and Italian. Did you always have a love for languages at school? Yes, I suppose I loved, I mean even growing up with English. I remember loving different words. For example, I loved the word ebony from Sleeping Beauty, I loved that word. That always stuck out for me. And I loved it, and of course I used it at school, but when I started French I really fell in love with that.  Yes, I trained over in Manchester. So I worked, I suppose most of my teaching career has been in the UK, but I moved back home a few years ago, and I had a job, a temporary position back in current school, and after that ended I suppose I was a bit at a loose end. So the masters beckoned the masters in translation in Queen's, and so I went ahead and did that. And I'm sure that you must find a big difference from teaching in the classroom and translating? Yes, I suppose there's no comparison really. As a translator you're really working on your own, whereas as a teacher obviously you have your students there with you, so there's a big difference, but the language I suppose ties both of them a little bit together.  Well, it's funny you should say that, because when I lived in Manchester, I did work as an interpreter as well in hospitals with NHS, so that was, I suppose, speaking the language, and then the translation I suppose came, I suppose while you do some translation as well, in teaching of course, but the translation then I suppose came really with the masters, and then my career as a translator since then. Fantastic. So I was just reading a little bit about the book, and it said it's a beautiful story about a son looking back and his child growing up in France after World War II. It captures all the memories, angst and regrets of a lost time and faltering relationships that cannot be recovered. So tell us about the book. When did you first discover this book, Anne-Marie? It was actually recommended to us by our grammar teacher at university, so she recommended the book to us, and I bought the book. I think we studied a page or two on a particular grammar point, and I read it and I loved it, and I just loved, you know, it's a very simply told story. It's very elegant, the style of writing, and so yeah, I really, I thought the author was very humble and honest in his account of his life, especially as childhood. Most of the book recounts as childhood. And you were saying that you really felt an affinity of the book and that the book would suit an Irish audience because of its universality? Yes, I think there are some strands to the book. I mean, the first thing he emphasises is that he grows up in a big Catholic family, so I think that's not sort of uncommon here in Ireland. So that's one strand, I suppose, the poverty as well. They grew up in an impoverished family, but they were rich in adventure, you know, childhood adventure with all his siblings.  He talks a little bit about the mystical Mosamie Shell and the myth surrounding that island. And, you know, about my grandparents, there was a giant grave, so that's a bit mythical as well, so there were different strands as well. I suppose growing up as a Catholic myself and going to Mass and remembering the altar boys in those days, ringing the bell, that kind of thing. And I think there's a passage about him being the altar boy and the rascality and the seriousness, the sadness as well. Yes, he recounts sort of a little mishap on his first day as an altar boy. So I'll not say too much, but I think he was happy that he wasn't at the high mass, he was at an earlier mass, so the congregation wasn't quite as full. And a variety of motions as humorous and as sad. And the French author Alain Rémont, I just googled him just to see exactly who he was. He's still writing, actually. He's quite a prolific writer himself, born just after the war. Yes, that's right. He has published quite a few books. This is the first of a trilogy, but he's also done some other biographies on, I think, Bob Dylan and Yves Monton, who was a French filmmaker. And he worked in cinema himself for a bit in his early career. And I think you might want to read a little extra from the book. There is a nice extract towards the start of the book. If I can just find it here. So the town he grew up in is called Trans, spelled T or I and S. So it's just a paragraph. So he says, Trans had become a magical country, a territory which had completely infiltrated our imagination and filled each of our dreams. That of the group of youngsters who walked along the road. The names of farms and villages were as enigmatic as cryptic messages. La Croix-Ban, Cruand, Le Rocher-Tocque, La Croix-des-Bois, Les Places, La Villages, L'Ante-Chauve. We gorge ourselves on mystery. Invented thousands of stories, head to the wind. Hands on our pockets, free as though in a dream. On the horizon, on the road to Plaine-Fugger, stood the Mont-Saint-Michel. When the weather was nice, you could just about distinguish it through the mist from the heat. In inclement weather, such as wind, rain or the cold, you saw it emerging above the bay. So distinctly and precisely that you could almost touch it with your hand. The Mont-Saint-Michel was in of itself a kingdom. A bottomless reservoir of dreams, legends, inventions of all kinds. In one of our magazines, there was the commendable story of La Fée des Crèves, The Fairy of the Strand, which took place right there on the Mont-Saint-Michel in front of her very noses. Both images stayed in our heads. The Mont-Saint-Michel that we saw, the one that trembled in the mist, on the road to Plaine-Fugger, and the other one, this mythical place from a piece of fiction which made our hearts race. We were living at the centre of the world. Lovely. Did it take you long to... Now, it's not a very big book, you know, but did it take you long to translate it? And was it a difficult job, Anne-Rie? Well, the style of the writing is very elegant, as I've said before. But yes, there were some expressions that he uses. So I had to do some research and make sure that I was getting the right meaning across. So it did... I did start it perhaps about three years ago before the lockdowns, certainly. So I think overall, I can't put an exact time, but I think several months too would probably be the right answer there. And I just asked you before we came on here that you haven't been in contact directly with Alan but your company or the publishing company has? Yes, so I had to contact Sawyer Editions in Paris, they who published the book, the first book, to get authorisation of them, and then, of course, of the author. And then, once I was given that, and then I attracted... You know, I sent a few chapters to different publishers around Ireland, and Shanley Press and Belfast came on board. They really liked the story, and then they sort of... I suppose did the negotiations then with Sawyer in Paris. But, yeah, it would be lovely to meet them, yeah. And you published the book just after Christmas? Yes, it came out in January. So it's selling quite well, and I'm starting to get some good feedback, which is delightful. Fantastic. How did you actually get the book? It's on sale locally. I started in Movil, my hometown, so it's on sale in Coscutters, there, and Gillan's shop. In Cairndonna, it's on sale in Fintons, newsagents, Max and Bongkranah, Bookmark in Letterkenny, and then in Dairy, it is on sale in Foil Books and Little Acorn Bookstore, and then online at Shanway.com. Fantastic. And what's next on the agenda for you, Ann-Ree? Well, currently I am teaching in Dairy, so I have that to keep me occupied. Just let's hope that we can get maybe the next book translated. That would be brilliant. And have you ever thought of actually doing a novel yourself, like from scratch, just not translating, off your very own? Yes, it has come across my mind before, perhaps to read something on my experiences in France, but I think it's going to be baby steps for now. Well, thank you so much for taking time out to talk to me, and the very best of luck with your book and with future projects as well. Thank you very much.


Your coca-cola bottler presents, Claudia, based on the famous play and novels by Rose Franken Brought to you transcribed Monday through Friday by your friendly neighbor who bottles coca-cola Relax and while you're listening refresh yourself Have a coke and now Claudia What's better than a good stretch? Especially when it's a home stretch I was gonna say fall is going to be beautiful here on the farm darling. Mm-hmm smells like fall tonight, doesn't it? Wonderful smell.  Don't settle down. I am settled down for a nice long evening by the fire without a fire The evening it'd be nicer if it were shorter only nine o'clock Mama's gone to bed if it's good enough for her mama had a headache. I could work one up if I tried save your strength What are you going to do I might do a little work on the new red school house work You want to be kept in mink don't you? Oh, well, I prefer muskrat leave them for muskrat I have to do some homework then skip the muskrat I wear sable Young woman if you're trying to we do me into spending an evening of idle chatter I'm not interested in idle chatter. I'm busy. You don't want to talk at all. No You really don't want to guess you don't I? Can take a hint and take it all right all right all right? Oh Mr. Naughton. Oh Fred's just a man. I wanted to talk to it's what is it you have that I haven't What is it mrs. North that's what I wanted to know ain't no attention to her fridge I was just thinking coming out to the kitchen. There's something. I want to talk to you about yes Well first try some of this new tobacco. See if you like it Yeah, we're like go ahead David has cans and cans of it Rich client. I smoke it later. I don't need to be so formal with me for it smoke it now. Well, yes Thank you Are you coming on the place you still up your ears and work? Oh, no besides working on this land.  But what for now? I was thinking of clearing out that underbrush behind the pasture.  I do it myself quicker and better I dare say you were must kill yourself working. I don't worry. I am the first to say when it is too much About how many those matches and we have still no animals on the farm So I am practically with nothing to do Some day. I hope you don't count your chickens before they hatch. It's not chickens I can't but cows and pigs and well, we have to take that work seriously Well, the farm is not a farm without animals and I promise you would not need any more help I am a very good hand with animals. You don't have to tell me Hmm, which are fine tobacco. Mr. Northman sounds fine. Very fine. Hmm here. I have an extra can Well, I did not mean of course. You did of course. Oh, well, I Clear up the underbrush at the end of the week. Well, good night. Good night to breathe it for us. Yes David, why should we be so blessed? But we are Have a chocolate. I'm smoking my my pipe Claudia. Don't squeeze the chocolates like that I'm looking for one. It's not figs or coffee. I'll take pot luck. It's rude to poke. Oh I got a green one. Uh here. I'll take it I thought you were smoking your pipe. Well, green one is Marzipan simpleton what Marzipan I mean. Oh, I always wondered how you pronounce it I detest Marzipan. Well, don't take my word for it Think I'll come out Shakespeare's hairballs Now that's one of your better ones Better ones. What non sequiturs all them While you come out Shakespeare's hairballs, maybe I'll get some peace and quiet. I'll tell Shakespeare. You're working Can you call him quietly? How would he hear cats have a sixth sense, but I haven't you haven't got one. Oh, you're so sweet to me darling Maybe he's going upstairs Now what would he do that for? Peace and quiet. I hope that cat's hiding in the attic now Hmm bub's dim in this life Where is that blast? Don't tell me Shakespeare's keeping watch over Bobby come on in I want my fountain pass It's in the pantry. Come on. What's it doing in the pantry? I needed it Look, baby. That's what?   Oh, that's what you think Except I don't think you do either. Oh David He's ours Hey, you're only supposed to kiss babies on the cheek Don't tell me but it's It's different with wives So come here. I'm glad I'm not a baby Claudia What about his belly? What about it? He has one. He's supposed to will he Outgrow it. Of course you'll outgrow it. I hope not too soon. No, I love it Well, don't make a sissy out of it. He's only two and a half months Little while longer won't hurt him. You don't think it's some Sort of silly to go downstairs again When our bedroom is right here down the hall, did you see my fountain pen was in the pantry?  Well don't loiter. I never loiter Shakespeare here you are. Come on Shakespeare.  I haven't even touched you So you don't have to cry in case now Be quiet. Hey darling. Did you receive a notice of a life insurance premium? No Anybody had sent a check. I'd remember this isn't a check. It's a bill You said it was a premium. Well a premium is a bill for an insurance premium You're getting repetitions. Now all I want to know is did you receive it? If it's a bill It's in the top drawer. If it's a premium. I don't know where I put it Maybe I filed it under pee pee Only I haven't got a file What do you want with it anyway? I want to pay it. I Thought life insurance was money you receive not gave out heaven grant me patience I thought it was all velvet. You know better than that now stop trying to act dumb.  You've got to look look right through right right right there through the window Quick put out the light. I will not put out the light. It's a harvest moon Great big orange Brown make a wish you only make wishes on new moons.  Terribly the light out the moon's twice as bright It's beautiful apple tree Will be fall soon in winter David don't work on the school house plans tonight Don't do that life insurance thing either, please.  It's Tennyson Anyway, we should be what? happiest Kings I'm as happy as kings Are you? But before we go up to bed, I'm going to fill out this insurance premium thing. Where's the checkbook right there in the second drawer Why do you always have to do something first before you do something else because that is life?    How can you be so silly?  I wouldn't kill myself. What about Bobby Bobby wouldn't matter Yes, he would he'd matter more than anything David, please Claudia You're crying Hold me tight Little fool darling, what's the matter? I don't know.  You're trembling The spirit must have just walked over my grave a minute ago. You were so happy as king. I still am I guess What's the matter now? Come on. Tell me. I Don't know. I just can't explain Maybe everything's too perfect as if it just couldn't keep on that way Ritz and the farm and Bobby and nothing's going to change a harvest moon Everything's so quiet David let's go up. I should have known I wouldn't get any work done. Don't jump darling. Can't you tell me? Just as if I'd said goodbye to what to who I don't know to this whole evening that was mine and yours No, it's gone by there There will be others of course there will if you say so tomorrow night The moon won't be so fallen Tomorrow is Never the same tomorrow might be better. Come on. Let's go up Remember the old cracker barrel around which folks used to cluster in general stores Sometimes nowadays it seems the coke cooler has taken its place You'll find a Coca-Cola cooler in shops and stores of all kinds today But it serves as more than a pleasant meeting place. It also helps you shop refreshed. Oh, mr. King Yes, Fred's you smoke a pipe. Yes, occasionally. Would you care to taste some of this excellent tobacco? Mr. Norton gave me why I wouldn't mind if I did good. I bring you some I Smell rain for tomorrow. Oh, no the moon's out after the moonshine rain after the light dark After the pleasure of sadness just a saying fritz.  I Bring you the tobacco do that and thank you Every day Monday through Friday Claudia comes to you transcribed with the best wishes of your friendly neighbor who bottles Coca-Cola So listen again tomorrow at the same time And now this is Joe King saying or of war and remember Whoever you are whatever you do wherever you may be when you think of refreshment think of Coca-Cola Or Coca-Cola makes any pause the pause that refreshes and ice-cold Coca-Cola is everywhere These broadcasts are adapted for radio by mania star and the entire production is supervised and directed by William Brown Maloney and now here's a word from your friendly neighbor who bottles Coca-Cola
