Hey, how are you guys doing? This is Rich from Rich to Be Live. And recently I've been talking to you about pure extracts who seems to have huge news coming out almost daily. And I've been showing you the stock and I've been telling you that I thought the stock was at a bottom and they made me look good yesterday up 5% with some really big news. And the volume was almost twice as much as its daily average volume. And then they got news again today. And you can see that I was trying to say that 50 cents was the bottom and there was some good upside. I drew this trend line here because I felt like there's a very good chance that we're gonna see it go higher. It did go higher yesterday. I think there's a good chance it's gonna go higher again today with this news. This is the Canadian side, as you could see here. The US side is PRXTF. And I find this to be a very interesting company because you can see it consolidating. I like this consolidation. Typically what you see before stocks explode is you see this consolidation or even sometimes they drift down and consolidate. And it's like a yo-yo or kind of like an elastic band. And what happens is when it really cranks back it's getting ready to just explode. And typically it just needs news and the biggest catalyst is always revenue. The biggest catalyst is always growing revenue. And this is a company that's growing and it's revenue. Now let's talk about the news because the news is always the biggest catalyst for these stocks. Like I said, the biggest catalyst is always revenue or news that means that revenue is coming. And let's talk about this news. Pure Extracts submits dealer's license application to Health Canada. This is breaking news. Pure Extracts Technologies Corp. Pull PULL in Canada. PRXTF in America. A2QJAJ in Frankfurt, Germany. Is a plant-based extraction company focused on cannabis, hemp, functional mushrooms, and the rapidly emerging psychedelic sector is pleased to announce that it's wholly owned subsidiary. Pure Mushrooms Corp. has submitted an application to Health Canada for a dealer's license under the Controlled Drugs and Substances Act, CDSA. The CDSA and its regulations provide, among other things, the framework for legal access to controlled substances and the control and regulation of production, distribution, and sale. One of Health Canada's responsibility is to provide the licensing and oversight framework for the legal production of controlled substances. Under the framework, a company is required to obtain a license issued by Health Canada in order to conduct various activities with controlled substances. License holders are responsible for compliance with the CDSA and its regulations, as well as compliance with other applicable federal, provincial, and territorial legislation and municipal bylaws. The issued license dictates activities, conditions, and restrictions for the license holder, depending on license permissions. A dealer's license could allow for the following activities, procurement of controlled substances, including by import, synthesis, propagation, cultivation, harvesting of psychedelic mushrooms, or psilocybin extraction. Huge research and manufacture of controlled substances, such as psilocybin and psilocin, business-to-business sale of controlled substances, including by export, and sale of controlled substances by pharmacies. Wow, this is big, guys. Very big. Pure Extract CEO, Ben Nikoleski remarked, we are grateful to have the support of one of Canada's premier consulting companies with subject matter proficiency in cannabis and other regulated consumer product industries in assisting that we submitted a fully compliant dealer's license application to Health Canada as a plant-based extractor bringing functional mushroom products to market in Q1. We are very excited to be laying to groundwork for our move into the controlled substances world of psychedelic extracts, which means they are so close to actually having revenue. So close, having the ability to do extraction research and development into psychedelic compounds, such as psilocybin and psilocin, will prepare pure extracts to work with partners such as medical doctors, pharmaceutical companies, and pharmacies as clinical trials lead to the legalization of psychedelics, and the advancement of microdosing in the near future. Submission of the company's dealer license application is subject to compliance with applicable securities laws, including any necessary approvals by the CSE about Pure Extracts Technologies Corp. Pure Extracts features an all-new state-of-the-art processing facility located just 20 minutes north of world-famous Whistler, British Columbia. The bespoke facility has been constructed to European Union GMP standards, aiming towards expert sales of products and formulations, including those currently restricted in Canada into European jurisdictions where they are legally available. On September 25th, 2020, Pure Extracts was granted standard processing license by Health Canada under the Cannabis Act and the company stock began trading on the Canadian Securities Exchange CSE on November 5th, 2020. Huge news for Pure Extracts, and it seems as though they have lots of news, and I like companies with robust news. If you wanna see a company do well, typically the company has to have news. That's how they communicate with shareholders. That's how shareholders get a chance to know what the company's up to. You could see the news here. I mean, they just put out news yesterday saying they've got $650,000 in orders for vape cartridges, for 30,000 vape cartridges, which I covered. Now today they've got news of submitting a dealer license application to Health Canada. They're constantly putting out news, and this is, see here the listed shares out, 79 million shares listed issued and outstanding, and a market cap of 46 million, only a 46 million market cap. That's a baby market cap. I think that the upside is tremendous for this company. I think they can easily go to a 100 million market cap, which in my opinion tells me that this can easily go to at least a dollar. And if this goes to a dollar, and you're in at 45 cents in Canada, in America, and you're in at 58 cents in Canada, the upside is tremendous. It's almost 100% upside from here. So love to know what you guys think. This is big news. Would not be surprised to see it continue further up. On this news, love to know what you guys think.

Cal OES logo inside. Look OES news.com. Hi, I'm Brian May with Cal OES. We are in the heart of Guernville, just about a block off of Main Street. And if there are two things that have been consistent, both here and throughout Sonoma County over the past several days, the relentless amount of rain and piles of debris. Men slide a metal appliance into a dumpster. A seemingly never-ending parade of vehicles lines up at one of the debris drop off points in Guernville. As Sonoma County residents clean out from the recent floods, this debris drop off point is being provided by the county to help speed up the process. But residents need to know what they can and can't drop off here. What we're doing is providing dusters for flood debris removal through the county. And we are taking basically disposable material, metal appliances. We do not take any hazardous materials, any televisions, electronics, paint, fluorescent light bulbs, batteries, anything like that. Across the Russian River, teams of county, state and federal crews are going house to house, checking on damages, answering questions, and just providing face-to-face contact. It is rather important as these teams go out, they might need to ask additional questions on what was the level of impact to be able to properly understand the complete picture of what has happened. Because just by looking on the outside, these teams might not necessarily be able to properly understand what exactly has happened to each home. Back across the river in Gernville, the local assisted center on Main Street continues to be a place where impacted residents can come with their questions and needs. A lot of people still have questions about debris removal. So we've posted some information on our website, socoemergency.org, about the debris removal sites. Those are open throughout the week, as well as summoned to next weekend. However, we know that people are waiting for volunteer organizations to perhaps come and help them with that debris removal, and we encourage them to keep just checking back in at our local assistant center, as there are several organizations who are starting to organize volunteers to help with debris removal. Outside the local assistant center, the Salvation Army serves up hot meals while the American Red Cross has passed out over 300 cleanup kits. From here on moving out, we're distributing from the local assistant center here and we're running some mobile routes as well to make sure that highly affected areas that may not be able to access the pods are receiving them as well. If you need any more information about the debris removal process or any of the services that are being offered throughout Sonoma County, you can go to the county's emergency website that's socoemergency.org. For all of us at Cal OES, I'm Brian May. Thanks for watching.


And the question is, why do people hate Israel so much? Why is there so many people who are pro-Palestinians? Think about Europe today. Think about, I mean, Europe is dominantly anti-Israel. I mean, I go to, I speak at the UK all the time. And the dominant people who are trying to obstruct my speeches and stop me, even though I'm not speaking about Israel, are pro-Palestinian groups. You know, in the US, I think that the number of people particularly among the young anti-Israel is growing. The boycott Israel movement is growing. And then there's the whole libertarian anti-Israel phenomena, which is just mind-boggling to me. You know, not really, if you understand what libertarianism is, but it goes against kind of their idea that they are pro-individualism, which at the end of the day, they're not. So what is your perspective on why people are so anti-Israel and pro-Palestinian? I think it goes to a moral premise that's prevalent in the culture. And I think it connects with both of those communities, both the sort of idealistic students. And if you want to put another category, the sort of libertarians that you're referring to, if you think of them as libertarians and it's not clear what that really means. So if you take students, and I've been on college campuses and I met a lot of these students, and part of what happens is this. So the moral premise in our culture is that there's a kind of sort of, you know, your attention, the premise is altruism, as Ayn Rand describes it. And I think it takes many forms. One of those forms is it programs people's thinking to be oriented to who's the sufferer, who's the underdog, who's down, and that matters. That's where your attention should go. And if someone is strong or productive or whatever virtues they actually have, real virtues we're talking about, then that's already suspicious, maybe even necessarily a problem. And you see this both in economic terms and you see it in foreign policy. And what happens is that if that's the sort of framing you bring to this issue. A lot of times you don't even look at the history. What you know is, wow, I feel really bad for the people suffering in Gaza. And look how poor they are. And Israel is so much stronger militarily and it's punching down and we're helping them. And the Palestinians have this whole history of and some of it is definitely something they accentuate and it's a big part of their propaganda. We're the victims here and we deserve your sympathy. And so if you're an idealistic person, the ideals that animate you often are, well, I believe in doing right and I believe in the good. And that means concerned with the suffering and well then sort of there's a default position that it's gotta be that the Palestinians have got something on their side and the Israelis, well, they're stronger. So we've got to be suspicious. And then if you fill that in with some of the arguments you hear from the sort of pro-Palestinian side of the Palestinian movement's argument, then it kind of reinforces that moral, what I think of as a prejudice, really, is the prejudice against the productive and the able in favor of the needy and the suffering. And part of what I argue in the book is that that's a corruption of the concept of justice. Like justice tells you not find the weakest person and be sympathetic to them because you can find lots of weak, small groups that are evil. Like, if you think of the jihadists, there are way fewer jihadists in the world than there are if you count every soldier in the US army. That doesn't mean you're sympathetic to the jihadists or, and then there are actually victims who are the underdog in a certain sense, who are innocent victims. So there's no necessary connection between being weak and small and suffering and actually having justice on your side. They don't go together necessarily. So what you have to do is actually judge and separate that out. And so what I think helps, what causes a lot of students and people on campus to be swept up in this is one part idealism informed by this kind of altruistic perspective that they've got to have. And, you know, the news coming out of this conflict is colored by this too. Like, look at all the people in Gaza who don't have water and their houses are bombed out. Okay, but why are their houses bombed out? What is the conflict read about? What do they believe needs to happen to their opponents? And talk about altruism just because you mentioned water. Israel is supplying them with the water. Whatever water they have in Gaza is being supplied by Israel, who has developed technology to desalinate the ocean. There's no water supplying Gaza other than what they get from Israel, which is an act of ultimate altruism because they're giving water to people dedicated to killing them. Yeah, and electricity flows and the control that. There's all kinds of ways in which that is playing out. Now, if you wanna talk about the other side of this, so another, let's make sure everyone understand. These two camps don't exhaust the sources of hostility to Israel, but they're significant for this audience because, I mean, and I think there's something good about what draws students to this perspective because it's the right premise to be on. Like, you wanna be on the side of the right, but how they think about what right and wrong and how to judge is that's the problem. That's what the book's trying to fix. Now, if you talk about the libertarian side, I think of that as a very fuzzy term, and I think there are at least two issues going on and they're both ultimately philosophical issues. One is, there's definitely people who are on that, kind of think of themselves as a libertarian whose moral perspective just is an altruistic perspective. They don't come at it, they don't come at their political philosophy from, I believe, in rational egoism and I'm an individualist to the core. Therefore, I think we need capitalism, which Sain Rand's perspective, for her, capitalism is the consequence of having a rational ethics that's individualist. And so their view is, well, libertarianism best solves for serving the needy in society, or their view is that, well, we need some sort of accommodation for the poor in suffering because that's their moral outlook, whether they recognize it or not. And that predisposes them to think, well, there's a whole bunch of poor people and they're suffering and then we gotta have some concern with that. And then the other thing that goes on for many people who identify as libertarian is, there's a kind of, this is certainly not true of all of them because there's really good people that I respect and think of themselves as libertarian, but there's this view of government as an evil. And in my view- It's not myself, no matter what its character is, yes. Right, and my view is government's a necessary good and that's why it's so important that you have a right kind of government. And so you look at the Middle East and you think, well, look at how controlling Israel, how strong it is and we don't like that. That's a bad thing. It's a government that's successful. We don't want any part of that. And it's this view that government is inherently a problem and there's other reasons they like, but to me it's not having a view of morality driving your political views. I think that's right. Now there's an interesting piece I read a while ago from, I forget, it's maybe the 60s or 70s by the famous anarchist libertarian, I think Marty Rothbard, I think maybe that. So he has a piece where he talks about Israel and the Palestinians. And one of the things he really kind of emphasizes is that it's, I mean, there's definitely sympathy to the Palestinians in that argument article. And it's surprising because the whole setup for the article, I forget the title, is we need deeper thinking on this issue. And the whole thing is incredibly superficial. It's like these are freedom fighters and Israel is just this too, it's a kind of religious tyranny. And even at the time that wasn't true. So there's just willful, unthinking approaches to this that I think are part of the problem. So. Yeah, no, I definitely think, I think the libertarian subjectivism there, again, some libertarians, their altruism, they haven't abandoned altruism, they consistently, so somebody here is complaining about Israel bombing children or bombing, bombing houses and so on.  So there's a pacifist element, but I think all of it would underlies much of these anarchist perspective is really hatred, hatred of the good. It's a certain, they hate America. I mean, Rothbard, it comes out of this Rothbardian view that there's nothing worse than the American government. The American government is the worst. Stalin is better than America. And yeah, and if Stalin is better than America then Palestinians are better than Israel. So it's hatred of any government that is somewhat successful, right? Even a little bit because they're successful. So they really is envy and nihilism and all driven by kind of a horrible, moral subjectivism. And then I would add, particularly in Europe, but I think also more and more here that there's definitely anti-Semitism, definitely an anti-Jewish aspect to all of this because they don't listen to facts. Anybody else can defend themselves. France can go to North Africa in Mali and bomb terror, the Islamists and kill women and children. And nobody cares. The French certainly don't care. But Jews defending themselves, that is completely unacceptable. That we cannot tolerate. If Mexico was bombarding a city on San Diego, would anybody be overly concerned, Americans about where the bombs were hitting in Mexico? The whole premise that they live under is there's a different attitude towards Israel because they're Jews, not everybody, but from some people there's absolutely no question, no question that they do this. Some people, why did France bomb Mali? Because Mali is a haven of Islamists and the Islamists were attacking France. And France went into, Mali's a former French colony I think, and they went in there to help the government defeat the Islamists. France has been involved in North Africa for a long, long time, justifiably or unjustifiably. My point is, all over the world, people are killing each other. Nobody cares. Nobody cares. But Israel kills anybody and it makes the headlines in every major newspaper in the world. Yeah, I mean, what interesting data point that people can look up is around the time of the first Gaza war, I think it was 2008, 2009, and that led to a whole UN inquiry about war crimes and so forth. Around that time, Sri Lanka was winding down. It's, there's an insurgency in Sri Lanka. And the way they ended this insurgency was through what's called total war. They just killed tens of thousands of people. And it was like crazy amount of death. And I forget exactly the timing of this, but it was around this time that Israel was being, you know, pulled over the rakes for its conduct in Gaza. And I write about this in the book too. But how much did you hear about what happened in Sri Lanka, which proportionally in terms of human lives and the cost and the amount of time it took in the, even the conduct you might criticize? I don't think you heard nearly the same amount about Sri Lanka as you did in terms of what Israel did, which was, you know, numerical terms much smaller. And the wider point is that this issue of the anti-Semitism that you're referring to, which I think one of the greatest manifestations of it, which really reflects a global perspective, is what happens at the UN. So there is in the, I don't know, 10 or so year, how long it's been that there's been a United Nations Human Rights Commission. They used to be a different body, but ever since they reformed it, and it's, as a rule, they have singled out Israel more than they have singled out any other country, including countries where we see people being killed in the streets like Iran, and you've seen it in Venezuela and in all parts of the world, those countries aren't given the same kind of treatment. And part of it is there's dynamics within the UN, which is heavily dominated by these dictatorial regimes and sympathetic regimes to them. But there is definitely a kind of, you know, sometimes it's put in terms of double standards, but I think it's worse than a double standard because it's giving a special negative focus to one country. Because it isn't like they hold it to a higher standard. There's arguments about whether you would hold it to a higher standard, but it isn't even that. It's just, well, who are they to do this kind of thing in the first place? And it is, anti-semitism is not a topic I get into much in the book, but you and I have talked about it, and you've given talks on the subject, and one of the things that people, I think, really need to appreciate is, this is a long-standing phenomenon, and it isn't really about religion, in the sense that there were cases in Europe so part of what led to the growth of Zionism, the idea that Jews have to have a country, is that there were secular, assimilated Jews in Europe, meaning they were indistinguishable culturally and intellectually from the people that they grew up with in Germany or France or Austria. And independent of all that, they were still pointed to in the street and called a Jew. Why? Because there's a kind of tribal collective and a racial component to it that you could never get out of it.  And I'm actually a fairly militant atheist in my view as atheists go. And when I was growing up, I was true to, and people still pointed to me and I got all kinds of anti-Jewish criticism and things like that. So there's a phenomenon that deserves real attention and it's separable from what Israel does, but it's now compounded by the fact that there's a whole country that people can point to and use as a whipping boy for this issue.


Hi, I'm Alex from Blackstar and I'm here to show you our new department 10, Amp to One. Amp to One is a 100 watt amp in a compact pedal format that can turn any pedal board or modeler into a performance ready rig. With three distinctly different pre amp voices, reverb and power amp response section, Amp One delivers the feel, tone and power of a traditional valve amplifier. Three stage power reduction ranges from full headroom 100 watts down to just one watt and enables you to dial in the perfect balance of power sag and response for any situation from studio to stage. The USA voice delivers a classic mid 60s American style tone very clean dynamic and bright with a solid low end and controllable mids. This is a really pristine tone that can complement your pedals really well. The UK voice has a medium to low gain pre amp that can be used clean or pushed into a warm overdrive just like classic British amps from the mid 60s. This is a popular choice for pedal platforms for the touch sensitivity and dynamics of the sound. The flat voice is designed to be used with multi effects pedals or modelers and delivers a transparent clean sound with a mix and desk style three band EQ. Using the flat voice, the Amp One finally unlocks the potential for live use of external modelers by restoring the feel and projection of a real amp. Our unique cab rig advanced DSP speaker simulator is built in which overcomes the shortcomings of impulse response snapshots and reproduces the sound and feel of a miced up guitar camp in incredible detail. Over 250 mic and cab combinations can be selected and output via balanced XLR, headphones, quarter inch line output and multi channel via USB. Amp to one has universal voltage input meaning your rig can now travel the world with you giving you zero compromises of your tone wherever you are. Amp to one always delivers what you need no matter whether you're recording playing on a silent stage or rehearsing in gigging and really need to move some air. Amp to one has you covered. The two built in nine volt outputs can also power your other pedals making the Amp to one the hub of your rig. You can build your rig around Amp to one as a high-headroom input stage is designed to work with pedals. Also you have the option for either series or parallel effects loop that can be controlled by the architect software. Architect unlocks deep dive editing features such as controlling your reverb size type and tone and effects loop controls. It's within architect that you can also dial in your cab rig presets. Let's dial in some tones. With 100 watts of power built in this is the ultimate compact amp solution. The Amp to one can live on your pedal board and be the hub of your sound whether you're connected to an on-stage speaker cabinet or going direct to front of house.


Okay, hello everyone. My name is Rafael Lima, and in my presentation today, I will tell you how LibreOffsCalc can now save server settings to the file. I will also tell you about a few more improvements that I have been making to the server, and a few other features that I plan to implement in the server for possibly the next release cycle. So, first of all, for all of you, if you don't know me, I am a professor at the Federal University of Technology in Paraná, Brazil. I teach, I do not teach computer science. I work for the industrial engineering department where I am responsible for the subjects of operations research, so therefore my interest in the server. I also teach statistical process control and also other subjects, such as logistics and production planning. So, I also do research using about machine learning, so how we can use machine learning in areas of industrial engineering, and also that's why I have some interest in macros and Python and all this stuff. And I have been a LibreOffs contributor since 2020 and a TDF member since 2021. So, here's an outline of my presentation. First, I will start talking about why the server matters. And then I'll move on to explaining what the problem is about not saving the server models. Then I will address the bug 38948, which was the bug that we were, where we were discussing this issue. Then I will talk about some ideas that I had to fix the problem, and then I will describe what was the actual fix that got implemented. To finalize, I will present some limitations that we have and then I will list some other improvements that I plan to implement for the server. So, why the server matters? So, the server is largely used in universities, both for teaching and also by companies to optimize real problems. So, universities we use linear and non-linear models, both for teaching and also for research. And in organizations, many real-world problems are modeled using linear and non-linear optimization languages. So, some examples are. So, we have production planning models, production scheduling. We have lot size problems, transportation problems, facility location, and vehicle routing problems just to name a few. So, in companies it's usual to have, we have some spreadsheets where someone has already set up the model so that the users can only input the data and run the model to get the optimized solution. So, one important thing about the server in the LibreOffice is that we offer very good server engines, especially for linear programming models. So, we offer out of the box LP Solve and also CoIMP, which are very good solvers. And they are far superior to the options that Microsoft Excel offers. So, if we use Microsoft Excel as an example, their server is limited to 200 decision variables, which is a small amount if you compare to the complexity of real words problems that we need to optimize with solvers. So, 200 decision variables is too few. And in LibreOffice, the solvers that we offer have no limitation. The only limitation is the model complexity, which is not something that LibreOffice would be to blame in this case. It's just the model that might be too complicated. So, we have very good options. We also have non-linear solvers, non-linear engine solvers that are good enough. They're compatible or competitive with other options that are available in other offsuits. So, this is one important aspect that we need to emphasize when it comes to solver in LibreOffice. Our engines are very good. So, why not saving the models to the file is a problem? So, in the university, one common problem is we teach a lecture or maybe we give a test to the students so they have to prepare a model, save the file and hand it to the teacher so then we can give grades to these files. And not saving the solver model to the file defeats this purpose, so it's impossible to use the solver for this use case. So, this is my pain because I am a professor, so I have this exact problem. But I've seen companies have the same problem because in companies, when they want to use the solver, they have to save it to the file so that they do not have to prepare the file every time to have things more automated. So, I have here a few screenshots of many requests in Bugzilla and also questions in Ask LibreOffice where users complain about the lack of saving the solver settings in LibreOffice. I just want to share an experience that I had because in my university, originally, we only had LibreOffice as our office suit in the entire university. But we had some professors that were pushing the university into buying Microsoft Office licenses and the lack of saving solver settings to the file, this item was one of the excuses that were in the report to push the administration to buy Microsoft licenses. So, this was said because I was basically forced to use Microsoft Excel solver for my operations research lectures up to now. So, because now it's possible, finally possible to save solver settings. So, now let's discuss a little about the bug, bug 38948, which was the bug report that concentrated the discussions and proposed solutions for this issue. So, it was quite popular, but not so much. It was reported a long time ago in 2011. It had four duplicates and 16 people copied on this bug report. And basically, people complained about two main issues. First, the lack of saving support and two, the need for compatibility with Excel files because it is expected that if a user creates a file in Excel with a solver model, it should be imported in LibreOffice and vice versa. So, in the bug ticket, many proposed solutions emerged. So first, we discussed, there were some discussions about the need to change ODF specifications to accommodate for solver settings. But this sounded too complicated. And to be honest, at the time, I think I wouldn't be able to do that. What people did to go around this issue, what other users did was create solver models using macros because it is possible to create a macro that run a solver model. So you can use the solver service and then you can create a macro and save the macro into the file. So then you are basically saving the solver model to the file, but in a very complicated manner because the macro is a bit complicated. Even for simple models, the macro is very extensive. So I have a few examples. I'm not gonna show them here, but if anyone is interested, I can show them to you. So this is what most people did to save models to the file. Then my first idea, instead of extending the ODF format, my first idea was to propose an extension that would automate the creation of these macros. So this would make it easier to create the macros and then save them to the file. I also thought about creating a separate dialogue using the basic IDE to recreate the solver dialogue and then save solver settings as an XML file inside the ODS file, which sounds complicated enough. So all these ideas were running through my mind. I never actually implemented any of these, only the macro variant here I did implement, but one day I was working on an Excel file in LibreOffice and by chance I opened the manage names dialogue. And then I saw this. I don't know if it's possible for you to see, but if you take a look at the name ranges that are here, you'll notice that they are indeed the description of the solver model. But in Excel, I remember not creating these names ranges. So then I realized that in Excel, the solver model is saved using named ranges. And this was a realization that I had that showed me the way of how I should implement this in LibreOffice as well. I don't know if you know this, but in Microsoft Excel, the solver is an extension and this is how they implemented it. Because along the way, I started realizing that many other extensions in Microsoft Excel use named ranges to store information in files. So here's just an excerpt of the workbook.xml file from an Excel spreadsheet that has a solver model. So you see that here we have a lot of defined names which is what they call it in Excel for each of the settings of a solver model. So one thing to note here is that in Excel, each tab has its own solver model. So we can have separate multiple models in the same file. So what I did is I mapped what named ranges corresponded to each portion of the solver dialog. So it's quite simple actually. So we have in the solver dialog from Excel, we have the named range that start that information. So what I did was basically figuring out what was the meaning of all the values that they used for each of the settings in the solver. And then I basically created the mapping mechanism between what was done here to the named ranges that were imported in LibreOffice. So let me go back just a bit because so why did I do it like that? So first I figured that because we have already named ranges support in LibreOffice, if I simply used named ranges as well, then we would automatically gain import and export support. And also if I used the same standard as Microsoft Excel uses for their solver models, then we would gain automatically interoperability support between LibreOffice and Excel. So this is why I chose this path. So here's just an overview of the patch. So here's the link for the patch. It has been merged some time ago. I believe it was in March. So this is just an overview of what was done. So first here we have the doc shell files because originally the solver settings in LibreOffice were stored here because we only allowed for one solver settings per file. So I removed it from here and placed it in the table file because now we can have one set of solver settings per tab. And also the other files. So here are the solver dialogue files where we basically load and save and update the solver settings from the dialogue to the object that stores the solver settings. And here is the implementation of the solver settings class which is responsible for storing to actually store the solver settings. So just to describe how it works, it's very simple. So in the SC table class, now we have a get solver settings method that returns a solver settings object if it hasn't been still created. So with this method, we can get access to the solver settings that are defined for that tab. So how does it work? Okay, so here we have a more detailed explanation. So when the user opens the dialogue, first the get solver settings method checks if the solver settings have already been read from the file. So what does it mean to read the settings? It means read the named ranges and convert them to the solver settings object. So if it hasn't been read already, sorry, if it hasn't been read already, then it is read. If not, it simply does nothing. And after the dialogue is closed, so the user changes the settings and when the dialogue is closed, the solver settings object is updated. Yeah, so this is here. Okay, so when the user closes the dialogue, the solver setting object is updated. So the patch goes on like that. It's very simple actually because after I realized what portions of the solver dialogue correspond to each named range. So the patch is now an effort of mapping which portions of the solver dialogue correspond to each named range. So here we have in this upper part, we have the main solver settings which are settings that are available for all models. And here we have in the part below, we have those settings that are solver engine dependent because not all of these settings are available to all solver engines. So I added all of them here, but not necessarily all of them will be available for all solver models, okay? So an important thing is that this part on the left are the names that are used internally by the LibreOffice solver service. And these are the named ranges used when importing and exporting the file. So, well, the main thing about this patch is that it's led to many other improvements that are required to make the solver in LibreOffice calc very competitive. The first of them is the need for support for hidden named ranges. So as I said earlier, when I first imported an Excel file with a solver model and then I realized that all solver settings were stored using named ranges, I first realized that they were actually being stored in hidden named ranges because in Excel they are, it's not possible to see them in the user interface, but in LibreOffice calc, we were capable of seeing them which is actually an interoperability problem because if in Excel a user creates a hidden range, named range, we should hide them in LibreOffice calc as well. So I created this, actually this bug report and also I have already submitted a patch that adds support for hidden named ranges in LibreOffice calc as well. So with this patch, it's now possible to import hidden named ranges from Excel and also from LibreOffice calc as well and also export. So it's important for interoperability because if in Excel or in LibreOffice calc, we want to have a range named range that is hidden from the user, we should be able to do so and import and export should work as expected. So just as an example, with the patch that is proposed here, which is by the way, not only because of the solver, but actually for named ranges. So with this patch here, I'm gonna zoom in a bit so you can see better. It's possible now to run a script like this. With this script, it's possible to hide a named range and then show the named range back, which is similar to what Microsoft Excel does because in Excel, it's only possible to show or hide named range via scripting, which is, I think it's by design because it's only meant for extension developers to use this, not for regular users. That's why you won't find anywhere in Excel's user interface an option to show or hide hidden named ranges. And from this patch that I proposed, it's only possible to show or hide named ranges via scripting. So this patch is still under review. Okay, so if any of you are willing to review this patch, I would be very thankful because it's awaiting review for some time now. So it's in Jarrett, it's from my end, it's working. And I have a few other improvements that I would like to do to the solver. So first, I would like to work on the solver dialogue user interface because I don't think that our user interface is very good, especially for large models. For example, here on the left, we have our user interface. And if we have a model that has like 10, 12 constraints, it's really hard to navigate through these constraints using a portion of the dialogue that only supports four constraints. So it's not nice if you want to see the whole model. Whereas in Excel's UI, we have something a bit, which I consider a bit better, not ideal, because here you can see more constraints in a smaller space. What I propose to do here is to have a tree view with three columns, so we can have the column headers, then we can have the left-hand side, the operator, and then the right-hand side of the constraints. I would like to propose too, in this portion of the dialogue, to allow the users to add separate objective cells to the model because both LibreOffice and Excel expect the user to select a range, then press comma, and then select another range, then press comma, and so on, which is very annoying because if you make a mistake, you have to start over. So what I will propose is to create a way where you can add each range separately, one at once. So you can have multiple objective cells ranges, but each entered individually. So these are a few improvements that I would like to do to the UI. Also a few more improvements that are still needed is first, improve scripting support because the current scripting support does not allow for us to create a script that adds the server model to the file, which I believe can be done by creating a recordable Uno command. So this is something that I'm still planning on working but I haven't started yet. Also, this is one thing that is quite easy to do because both linear solvers that we support, LP solve and coin P, they support a lot more parameters than we provide. So these parameters that the solver engines already support are easy to integrate in our solver implementations. So this is something that is easy to do and this will increase compatibility with Excel solver. So it would be better for interoperability as well. For instance, our solver does not support a very important parameter, which is the MIP MIP gap, which is probably the most important parameter that defines how much of gap do you need to achieve to say that a solution is optimal. And this is something that we still do not support. Well, in the future, but now this is something that is more to the future, I would like to integrate other solvers to Calc because we have some very important solvers that are good hobby and seplex, that are the industry standard, they are proprietary, but they offer C++ headers. So it would be possible to create an implementation of the solver service for these engines and because they are proprietary, we would need to allow the user to define a solver license so that they can run. So if the user has, for example, Grubby installed, they can set up where the license file is and then run it from within LibreOffice, which would be very good if we compare to other alternatives that exist today. So I believe that with these improvements, the solver in LibreOffice would become the best alternative among all the spreadsheet-based solvers. There are also other non-linear solvers that can be introduced to LibreOffice, for example, IPOPT, Bonn, Min and Coen, which are all open-source solvers. So we could also implement them into LibreOffice. And to finalize, I think that we should improve documentation, better describe what our solver engines are, how they are configured, what the parameters are. So these should be available in the help pages. And finally, a few limitations. Okay, so for LibreOffice 7.6, the hidden named ranges are still visible, but the patch that I proposed will probably only be available for 24.2, so these will be fixed. Also, there is a problem that I discovered this week while preparing the presentation, is that when you have a named range from Excel and it's tied to a tab instead of the whole document, when you save the file again, it gets lost. So it's a compatibility problem. I reported this bug in Bugzilla already, it has been confirmed. So this is something that needs to be worked on. And as I mentioned, another limitation is that not all parameters that exist in Excel are already supported in LibreOffice Calc, but this is something that can be easily worked on in the future. So that's it. I'd like to thank TDF for the support, for the funding for me to attend the conference, and also for everything else that TDF does, which is amazing. I also would like to thank the code reviews. So we have Thomas, we have Arkady, either I can say his name, but I'd like to thank Arkady and also Michael Mix because all of them were involved with reviewing the patch. So that's it. Thank you.


The DuPont Company of Wilmington, Delaware, makers of better things for better living through chemistry, presents the Cavalcade of America, starring Basil Rathbone. Tonight, from the stage of the Belasco Theatre in New York, the DuPont Cavalcade returns to the air for its 17th season. Our play, Towards a New World, is the story of Joseph Priestley, one of the immortals of science. Our star, the distinguished actor of the stage and screen, Basil Rathbone. The time is the latter half of the 18th century. The place, a brewery, near Leeds, England. I say, pardon me. What's that? Reverend Joseph Priestley, the minister. I'm looking for him. It's a bit unseemly, but I was told I might find him here in this brewery. He's here, all right. Oh, extraordinary. Do you think I might see him? See that bat, Yonder? The big one? See the fella leaning over into it? Yes. That's the minister. My word. What's he doing? Bubble collecting, like always. Bubble collecting? Extraordinary. I fished him out of the mash twice last week. Really? Get into the point where we spend more time, lift in the minister out of the mash than we do brew in beer. Well, thank you. Will it be all right if I go over there? Aye, but be careful. Don't you be falling in. Oh, I'll be careful. I beg your pardon. Here, hold this tube. The tube. Hold it. There. Now, put the end in the jar there. But look here, I say quickly. Yes, yes, of course. Is it secure? Yes, yes, I suppose it is. Now, hold me by the seat of my britches. Well, not really. Well, come on quickly. The best bubbles are in the middle of the bat, and I must get to them. Come on. Hold me by my britches. Well, all right. I've got hold. Hold tight. I'm holding. Now, the air bubble's coming up. A funnel right over that one. Fine. All right. Excellent. I think we obtained some wonderful specimens. These broodivates offer the best bubbles of air. I'm sure they are the same as Dr. Black's. Fixed air. Got them from Limestone, you see. They burst over the fermenting beer. Interesting. But what of it? Well, now to be honest, I'm not quite sure. Are you new here? New? Yes. I mean newly employed in the brewery. Now, I don't recall seeing you before. Oh, I'm not a brewer, Dr. Priestley. My name is Shelburne, Lord Shelburne. Oh, my goodness. I've come rather a long way to see you. Indeed so. Yes, I've heard remarkable things about you, sir, from my mutual friend of the Pennsylvania Colony, Dr. Benjamin Frazier. Oh, Dr. Biggs. Yes. You're the dignified minister who devils in chemistry. Most unusual. When I heard about you, well, I just couldn't resist the impulse to search you out. And why, sir? When? Because, in a sense, we are of the same species. The curious amateur, the inquisitive neophyte. Philosophical peeping tom. Exactly. Well, poor. Now, tell me, what have you here? In this jar? Yes, sir. What about the, shall I say, magic amethyst that you have collected from those mesh bubbles inside?  It's quite near here. Then you have found something. Oh, yes. Yes, I experiment. I dabble, as you say. And now, in my amateur way, I've found something. It's very exciting, but there's one thing wrong. Oh, yes? For the life of me, I don't know what it is. Come over here, my lord, essentially. Now, here in this jar, I have some of this peculiar air. Yes. I have a tube from this jar into this next jar that is half filled with water in this pneumatic trough that I've devised. Now, I put a little pressure on the air. See what happens. Ah, the air is passing from the bell jar to the water. Yes.  Drink? Yes. Well, why not it?  Come on, taste it. Well, now I... Well, he won't do you any harm. Look, I'll drink it myself. There. Now, you, just one draft. Well, I... Well, why not? All right, let me have the tumbler. Why, I say yes. Delicious. You see, some people travel all the way to Seltzer on the continent to drink the waters of the mineral springs. I go no further than the laboratory. But what produces the taste? Oh, this air is held trapped by the water. What causes the phenomenon? I can't say. But the result is tasty, if nothing else. Fascinating. Fascinating. Tell me, you don't just come upon these phenomena so easily. You must have had excellent training in natural philosophy. No, no, none at all. No? No, Franklin was right. The minister who dabbles in chemistry, a hobby, that's all. But what aroused your interest? Well, my lord, originally it was a series of lectures I attended while teaching at Wellington Academy. Then, by lucky accident, I met Dr. Franklin in London. He inspired me to investigate electricity. But I found my main interest lay in the nature of air. What is it? What is its mystery? And so I dabble. Dabble? Oh, nonsense. Dr. Priestly, I think our findings here are worthy of note. I'm delighted, Franklin spoke to me about you. This work deserves to be brought to the attention of the Royal Society in London. And with your permission, I'll see that that body grants you a formal audience. Oh, come on, my lord. I hardly think of it. Oh, I'll hear no arguments. I mean it. Yes? Joseph, it's supper time. Oh, it's Mary, my wife. Oh. Come in, Mary, please. In there. With all those violators, I should say not. Mary. Mary, dear. We have a visitor. Oh. My lord, may I present my wife? Mary, this is Lord Shelban. Lord Shelban. Well, we are honored, sir. I'm honored to be here. You have a gifted man for a husband, Mrs. Priestly. Thank you, my lord. Would you like some tea? No, no, no, no. This is not a formal call. Just dropped in to make my eyes believe what my ears have heard. Oh. Yes, and now I must be getting along. Dr. Priestly, you will write me as soon as it's convenient for you to appear before the Royal Society. I, uh, yes, I, uh, I'll think about it. Oh, no, no, no. Don't think about it. Just pack your kit and come to London. The meeting of the Royal Society is now adjourned, gentlemen. May I congratulate you, Dr. Priestly. And may I, too, sir. Thank you. Thank you very much, dear. Dr. Priestly. Dr. Priestly. Dr. Franklin. Well, what a wonderful pleasure seeing you again, sir. I came in a trifle date and sat in the back rows, but I saw everything. It was a superb demonstration, Priestly. But wonderful. I shook all the time. Well, you couldn't tell it at all. This is the most rewarding experience I've had since I've come to London. Everything I've done here in England for the cause of the American colonies seems to be ending in failure. No, no, no, no. I don't believe that. I don't believe that a righteous cause can ever fail. That may be true in theology. Alas, would it be true of everything else? Ah, enough of my troubles. This is your night. Your time. Thank you, sir. Thank you. And what is next? What black cavern of the unknown will you crawl into next? I'm afraid there will be no more caverns. This is the end. The end. You know, a good end, I suppose, but definitely the very end. My duties as a minister are crowding more and more upon me. I, well, I can't stand myself the luxury of a hobby any longer. Oh, nonsense, Priestly. It's not a question of excluding one worthy pursuit for another. Man has time for many pursuits. Cultivate this habit, my dear sir. You've begun well, indeed. Too well to stop at this stage. No, sir. Your experiments on the nature of air are far too important to halt. I have no choice. None whatsoever. I have neglected my family. And Dr. Franklin. Hello, gentlemen. I come with the most tremendous news. Oh, I have a passing reputation as a journalist. Well, every year. I've been doing a neat bit of eavesdropping. The awards committee of the society here has been in little huddle. And listen to this, Priestly. They are going to award you the Copley Medal for your discovery of ever-vessent water. The Copley Medal? The very highest honor of the Royal Society. Oh, Jesus. I am deeply touched. Well, I'll venture a prophecy. Before you are much older, you'll be collecting medals and honors as some people collect old buttons and snuff boxes. Oh, my dear sir. So, if you choose to regard your experiments as dabbling, my sir, my advice to you is to keep right on dabbling. There's no doubt of it. You're on the threshold of a magnificent career, Dr. Priestly. Well, the good doctor denies the fact, Lord Shilman. Didn't I? No, I'm sorry, my lord. But I can't go any further with my experiments you saw for yourself. Working in a brewery. My meager equipment, that tiny worksheet. Well, maybe I could spend less time on this hobby. The heaven knows I can't afford it. But I will not hear of it. I just refuse to hear of it. Well, I have no choice, sir. But you do have a choice. I make you a choice. I offer you my home. Your home? You will come to my manor at Cannes. I'll give you everything you need. Apparatus, books, time, a place to experiment. I'll provide you with an income suitable for all your private needs. And now, sir, you have a choice.  Accept. In the name of science and the never-ending search for knowledge. Accept. Very well. My lord, I am very grateful and exceedingly happy. I will come and work in your home. And now then, Lady Shelburne, you understand that I am most reluctant to intrude this distasteful matter upon you. Naturally, Mr. Cartwright. You must realize, Lord Shelburne, that the mere presence of this man Priestly in your household gives him a stamp of approval, an order of respectability. Oh, come, come, come. Get to the point. Well, my lord, what I mean is this. The townspeople are uneasy. There's a feeling that no possible good can come from Priestly's excursions into witchcraft and sorcery. What ruckus. Ah, but it has also come to the attention of certain quarters that he expresses himself, who are far too freely in religious and political matters. Dr. Priestly is employed by me, if you must know as a librarian, and to conduct certain chemical experiments, we both find extremely provocative. Obviously, as a dissenting minister, he must express his convictions, and his political views are his own affair. Mr. Cartwright, thank you for coming. You may rest assured that this matter will be considered by Lord Sheldon and myself. Well, thank you, Lady Sheldon. My lord, I bid you good day.  We will have an end to it, William, immediately. You will see that your friend Priestly is off these premises by the end of the week.  Priestly is harming no one. As a matter of fact, he's bringing us a great deal of honor. His discoveries in pneumatic chemistry are the talk of London. The Royal Society, considering one of the country's outstanding natural philosophers. And I consider him an undesirable employee.  Well, we'll talk about this some other time. We will talk about it now, and for the last time, William, either Priestly and his vile smelling collection of bottles, leave or I leave. What do you mean? I was just thinking, Sophia, it's an interesting choice. You are listening to the Cable Cade of America, starring Basil Rathbone and sponsored by the DuPont Company of Wilmington, Delaware, makers of better things for better living through chemistry. This week, some 18,000 members of the American Chemical Society are meeting in New York for their Diamond Jubilee. In honor of this occasion, the DuPont Company has installed an informative exhibit on the main floor of New York's Pennsylvania Railroad Station. This exhibit offers you an exciting glimpse of chemistry's part in providing you with better homes, clothes, food, transportation, health and recreation. The DuPont exhibit will remain in New York until next Monday. Beginning September 13th, it will be on display in Union Station, Washington, D.C., for the meetings of an International Chemical Society. So if you are in New York this week, or in Washington, between September 13th and 23rd, we invite you to visit the DuPont exhibit of better things for better living through chemistry. We continue our DuPont play, Towards a New World, starring Basil Rathbone as Joseph Priestley. In his little workshop on the estate of Lord Shelburne at Con, England, Joseph Priestley, minister and amateur chemist, is tirelessly working to conclude a series of historic experiments. He is unaware, however, that his position in laboratory work are threatened by the fears and prejudices of the townspeople. Come in. Come in. Oh, Lord Chilbert. Good afternoon, Priestley.  I wanted you to be... Priestley, can you put your work aside for a few moments? There's something I want to discuss with you. I've come upon the most extraordinary phenomenon. You see, it's about... Phenomenon? Yes. Yes. Frankly, I'm not certain what to make of it. Well, that sounds interesting. Let me see. Let me see. Well, it began in the afternoon, yesterday afternoon. Yes. I was experimenting with a new 12-inch heating glass on some red precipitate of mercury. Now, I found that air was being expelled from the precipitate very readily. And this air, I collected in the bell jar. Now, what type of air is this, I said to myself? Air extracted from mercury. Oh, that's extraordinary. Well, I decided to find out. You know, I took the candle. Yes. As I take this candle now. And I placed it in a bottle of the trapped air from mercury, as I do now. Well, the flame, look at it. It's doubled, tripled in size. And the way it glows, white hot. What is the explanation of this phenomenon? I admit my ignorance, it's beyond me. But it concerns the nature of air. In what way? Well, I don't exactly know, but what I should really like to do is to bring this to the attention of some great chemist who could explain all this to me. I mean, all my experiments. Ah, Lavoisier of Paris. No chemist in the world is this equal. No, no, no, no, no, that's out of the question. I can't go to Paris. Wait a minute, wait a minute. Bye, Joe. Lady Sheldon shall have her wish.  Only I shall leave with you. We'll both go to Paris, to Lavoisier. Mary, my dear, what's the matter? Nothing, dear. Oh, come now, come now. Why, why the tears? It's nothing. Oh, tell me, please. It was silly, but oh, Joseph, it hurt me so deeply. What, what did? I was shopping at the market and some people. Oh, I suppose they meant no cruelty, but they hooted and laughed and made some terrible remarks. They called you a dissenter, a non-conformist because you don't believe in worship the way they do. They even called me a witch. Ah, fear and prejudice. Well, my dear, a prettier witch never bestowed a broomstick. I have an idea. Tonight we shall ride tandem and cast a spell over all the prattle mouths of Karen. Joseph, why must you keep meddling with parts and jars all the time? You say yourself. You don't understand some of these things you've come upon. I don't know, Mary. Not a trained chemist or scientist, I know. But something keeps me at it and I can't stop. Don't you understand that a man may be compelled to act sometimes even against his will? Oh, I, I know it's been hard for you all these years, Mary, dear, no money moving from pillar to post. Tell me one thing, dearest. Are you happy doing this dabbling, this experimenting, even though you feel you're lost? I love it. With my whole heart. Then keep at it, Joseph. Go to Paris. See your Levoisier. I only hope he appreciates you as much as I do. It, uh, it's kind of you to see us, Monsieur Levoisier. Yes, yes indeed. Oh, you are welcome, Lord Shelburne. Thank you. And Dr. Priestley comes to Paris with the finest reference. The name Benjamin Franklin, a good man, a great man. But now, before we begin, I have a basic question to ask you. Well, I'll try to answer it. You think you have made a discovery of certain importance, trivial or otherwise, remains to be seen. Now then, I ask you this. What do you think you have found? I think I have found air in its pure state. The true element. So, well, let me hear the details. My experiment was simplicity itself. Now, I started with two bell jars. One I filled with common air. The second I filled with the new air I discovered. In each jar I placed a little mouse. And then? Well, 50 minutes passed. The mouse in the jar with the common air was dead. Suffocated. Yes, but the other in the jar with Priestley's air was alive. Yes, yes, alive. Alive and scabbling about like a bumblebee in a bed of flowers. Five minutes passed, then ten, and he was still alive. Still scratching the side of the jar, wriggling his tail in protest. Exactly, that's exactly what happened. Usual. Most unusual. What do you think, monsieur? What is it in the air? I have discovered and put in that one jar to keep that mouse alive. I do not know. But I will think, and I will ponder. And after I do that, I will see you again, Dr Priestley, and answer your question. And here, gentlemen, are my conclusions. As you know, for ages, for all the ages of man, people have wandered over the mystery of the atmosphere we breathe. Some have come to the threshold of the true nature of air, but none before has crossed it. You have crossed that threshold, Dr Priestley. My friend, I have duplicated every one of your experiments with candles, with mice. I have done them twice, then twice again. And the result is always the same. I knew it, Priestley. I knew it. Oh, how wonderful. I'll tell you exactly what you have done. You have led us, Dr Priestley, to what chemists have been searching for for centuries. You have discovered an element, a new element, the most abundant element on earth, and it is that element that may help us understand the true nature of the atmosphere. But I am just an amateur. I'm not the man who should come upon a thing so great. Oh, you must search for knowledge. The chimney sweep stands on equal footing with the chancellor of the Sorbonne. It is never who finds a thing, but what a man finds. So, Dr Priestley, I ask of you one favor. Let me send Godfather to the child of your genius. I will give this discovery a name. I'd be honored, sir. Good. Because I believe this, to be an ingredient of all acids, I name it Oxygen. That is taken from two Greek words, meaning acid producer. And I say this. Oxygen. I say this to be discoverer of Oxygen. Keep on. Never step aside from the path you are traveling.  Never say what you do is dabbling.  Keep on, Priestley. You must keep on with your experiments. Yes. There was a time when I thought it was a matter of choice. But I was wrong, of course. Life is not divisible, nor is it labor. It is a unity, an element, in a sense. Like Oxygen. Oxygen. Monsieur Lavoisier. It has a most pleasant sound. Joseph Priestley continued his experiments. Then in 1794, beset by religious and political intolerance abroad, Joseph Priestley came to America and settled in his friend Benjamin Franklin's Pennsylvania. Here, before his death in 1804, he discovered a new gas, now known as carbon monoxide. He formed friendships with Benjamin Rush George Washington and Thomas Jefferson. In 1874, on the centennial anniversary of his discovery of Oxygen, the organization of an American chemical society was proposed by a group of chemists making a pilgrimage to his home in Northumberland, Pennsylvania. This home is now a memorial. Today, the society's Priestley Medal, the highest honor in American chemical science, commemorates the work of this gentle minister, who, though not a trained scientist, persisted in his spare moments in experimentation and led the world of science towards a discovery that had baffled great minds for centuries. The true nature of the Earth's most abundant element, the air. To Basil Rathbone and the DuPont Cablecade players for tonight's DuPont play, Towards a New World. And now, Bill Hamilton speaking for the DuPont Company. Tonight opens the 17th season of the DuPont Cablecade of America. Each Tuesday evening, as in the past, Cablecade will bring you a true story of men and women who have helped make America the great nation it is today. A true story that is dramatic and inspiring. DuPont also brings you news from the exciting frontiers of research in chemical science. Spot news of better things for better living through chemistry. One piece of news this evening is about the 18,000 men and women interested in new scientific developments who are meeting this week in New York City. This meeting of the American Chemical Society marks its 75th year, the Diamond Jubilee. In the lifetime of this organization, its members have accumulated a vast store of chemical knowledge. This knowledge is an important key to the better living we enjoy in America today. These scientists are meeting to talk over their mutual problems, not because any government has ordered them to, but of their own free will. In America, they are free to think as they like, say what they like, and do the kind of research they like. That is one of the chief reasons why American science is great, because it is free. It is freedom of inquiry that permits American scientists to gather knowledge without hindrance. And it is freedom of enterprise which permits American business to convert so much of this knowledge into the way of life which Americans enjoy. Among the scientific achievements which serve you are many of the DuPont Company's better things for better living, through chemistry. Next week, the DuPont Cavalcade will present two stars, Lorraine Day and Thomas Mitchell. Our play, No One is Alone, is the story of how a human derelict was restored to dignity by the faith of a woman. Be sure to join us. Tonight's DuPont Cavalcade Towards a New World was written by Irv Tunick and was adapted from a chapter in the book Cruciples by Bernard Jaffe published by Simon and Schuster. In support of Basil Rathbone on tonight's program, Alice Frost was Mrs. Priestley, Mercer McLeod was Lord Shelburne, Ronald Long, Benjamin Franklin, and Ross Martin was Lavoisier. Music was composed by Arden Cornwell conducted by Donald Borey. The program was directed by John Zoller. This is Cy Harris speaking. Don't forget, next week, our stars, Thomas Mitchell and Lorraine Day, our play, No One is Alone. The DuPont Cavalcade of America comes to you from the Velasco Theater in New York and is sponsored by the DuPont Company of Wilmington, Delaware, makers of better things for better living, through chemistry. Now here, Brian Donlevy and his dangerous assignment on NBC.
