So, as you see, if you have, I love to have very good qualified questions at the end, because at the end, that's where all the things that I've forgotten to say is what you're going to make me say by stating very good questions. Also I tend to surprise myself with what I say sometimes, and then it's kind of funny if that happens, if that ends up on Twitter. So if anyone likes to eat Swedish licorice, you will get that if you do a good question or if you're doing a good tweet. There, this one. Who am I? I'm a software tester. I'm a security tester to be. A little bit of DevOps, a little bit of everything. I also am a maker. I really, really love making LEDs like those, wearable LEDs, and I have a chip implant, and sometimes I go and talk about that as well. It's too bad. I had a really nice presenter mode before, and I don't have that anymore. I will have to do it. This piece of art here is very well-known in Sweden. It's painted by an artist called John Bauer, and it's been said that the model for this little elf in the middle is his wife Esther Elqvist Bauer, who was also an artist. And in 1918, they were going to take a boat over the big lake Vätten in Sweden up to Stockholm. They had the option of going by train, but about one month earlier, there had been a huge landslide. Because of the landslide, the railroad simply disappeared, and 42 people died in a fiery inferno train accident. Therefore, they felt it didn't feel really safe going by train. Boats are much, much safer, and so they bought a ticket for that boat. Another person who also bought a ticket for that boat is Viktor Fong, which is my great grandfather, my mother's father. He was a yellow metal worker, founder. Basically he's making chandeliers for churches. And one of these days, he was going to take this chandelier up Lake Vätten on the boat. He also bought a ticket, and it was very bad weather. It was in November. Sweden in November is well known for not being like Thailand, but more kind of awful. And the boat sank. And the people on the shipping, in the shipping company, they went through the manifesto and they saw Viktor Fong on the manifesto, went to his wife and said, we are very sorry to inform you that your husband is dead. And this would be devastating for them because they had seven children. And the wife, Ellen Fong, said, no, well, no, he isn't dead, he's in the workshop. It turns out that he was the only person who was denied entrance, although he had a ticket. For some reason, one skipper said, you're not, this is not the boat that you're going on. And he, we don't know why because that skipper also died. So Viktor Fong was the sole survivor of the boat accident in 1918. And what's also interesting about this story and the reason why I want to talk about it is that 360 days later, my grandmother was born. So that's kind of crazy. There was an investigation into what had happened in this accident. As much as two thirds of the cargo was put on deck, this cargo was also unlashed. So it wasn't anchored to anything, but it was just standing there. It was sewing machines, it was potatoes. It would have been a chandelier, but it wasn't. They were standing on top of the boat instead of downstairs. And I think also at the time it was common knowledge that if you're having a boat, you need to put the weight down below, because if you don't do that, it will tip over in bad weather, which is also what happened. This accident investigation blamed the captain for all of it. They said it was bad seamanship. But in reality, the shipping company had a bonus system that, and it was put into system throughout the industry, basically, that you do put cargo on top of the boat instead of down below. And if you look at this boat, like, I don't know, who would blame them? In 1918, Sweden was one of the most poor countries in Europe. We didn't have democracy, we didn't have, people didn't have food. Fourth of the population was in America. So everybody is working, is working very, very long days.  And if you're having a big sewing machine, how are you going to take it down there? It's very, very hard if you're designing a system, or in this case, a steamboat. A 100-year-old steamboat at the time, too, because it was born in 1970. It was built in 1950s, something. It's just very, very hard to do the right thing. These people are already working very, very much for a very, very little wage. And these tickets are already very expensive. So there is a best practice, a best practice that will save lives. But still it is disregarded by most. So as far as I know, shipping didn't become very much secure until we have a technical solution that makes it drastically cheaper to unload and load ships. You don't have to balance with ladders, but you're solving things with technology. And it's much, much easier to operate these kinds of boats safely. Therefore, we also have much, much more cargo, because it's much cheaper, much better. So I would argue that the IT business is as mature as other businesses, like civil engineering or shipping engineering, were 100 years ago. And my hope is that the general data protection regulation that is coming into force now in May will be one of many steps into making IT safe and secure. But we don't know this. Like, I'm very enthusiastic about GDPR, but that's also simply because it's not there yet. No one has been fined yet, and we don't know how it will be interpreted. We do know what the law says, however, and I think that the law in itself is quite radical. So since we don't know how this will actually be interpreted, I can give you absolutely no answers about what the GDPR actually is, but I can define a problem set to assess your own systems by. But for that, one of my biggest idols is called Bruce Schneier. He's an IT security guru or whatever. He's writing a book right now on how we can regulate the internet of things. He thinks that there are two paradigms of security. One that is the highly regulated security of dangerous things. Dangerous things are things that will kill you if it goes wrong, like boats, or medication, or buildings, or electricity. This works with harsh legislations and pre-certifications. For example, if you have a medicine that will be miraculous and cure cancer and HIV and everything at the same time, you still have to go through a ten-year process before you let it go into the market, whereas we in the IT business, we can ship anything all the time. This paradigm of highly regulated security inhibits innovation, but it prevents failure, and therefore it also prevents death. Whereas we have the agile, patchable security of previously benevolent things, and that's software and stuff. Or for example, when it comes to environmental seals, we also very much see this like a voluntary approach or a approach with shaming or with trying to pressure an industry into doing something. And the agile, patchable security paradigm, it promotes innovation and it accepts failure. That was okay. As long as we didn't have internet-connected cars. That was okay as long as, you know, for example, Tesla, during one of the storms in Florida, they simply sent out a patch for people that were driving Tesla cars so that they could drive a longer distance on their batteries. So that was really nice in that case, but they didn't ask for permission in advance. Is this something that we really want? Do we want companies to be able to update our software over the air just like that? I don't know. So how come dangerous things are reasonably safe? So in the case of the boat in 1918, I think one of those boats, those tickets must have been very expensive. It's something that most people couldn't afford. So there must be some kind of equilibrium where it's secure enough so that people buy tickets at the price that they can afford it. Then there's an accident happening. Most of the times there is no accident happening, but some other times there is. And when that accident happens, usually there is a cause that is determined and hopefully the cause that they find is actually the one that was actually causing the accident. These markets and people, they push for better security, and we get better tech, or we get a more expensive product, or we get some kind of pre-legislation. Most of the time we get all three at the same time. And we don't really know for sure which one of them necessarily is the one that causes things to start working or things to get better. The new technology will also make things worse, and very often the new legislation will maybe solve that thing, but it doesn't solve another, it causes another problem. Anyway, we will end up with a new equilibrium of profit versus caution, and we will probably have something that is a bit more safe. So we can see now that medicine is probably more safe than it was 50 years ago. We don't have a new contra-gun accident every week, and this feedback loop works because we people care about dying.  So there is a market pressure because people don't want to die. People, politicians think that people don't want to die, therefore they want more better legislation. Whereas in IT, we still don't really care about the fuck-ups that happen. But hopefully we'll do very soon. So let's go over to the GDPR. The most important thing about the GDPR is that European citizens own their own privacy data. And in order for us to invoke our rights as owners of our data, IT systems need to be built with privacy by design. Both of these things, what are privacy data, what is privacy by design? We also need to have informed and granular consent. And we who collect and process data, we cannot anymore say, oh, I didn't know that an unencrypted S3 bucket was unencrypted. I'm sorry. But you will actually be fined. But you won't be fined before. An interesting thing is that you can have two equally bad systems, and only one of them will have a breach. And that's the one that will be fined, probably. And the other one will just, oops, repatch this. No one noticed. Great, we won't be fined. That's something that might happen, but we don't really know yet, because as we know, hasn't happened yet. When it comes to the GDPR, we often talk about personally identifiable information. And this is actually something that is not inside the European legislation, but personally identifiable information is something that they can talk about in the US, for example. And there it is very clearly defined what is and what isn't personally identifiable information. Whereas here, accounts should be taken to all the means reasonably likely to be used. What does this mean? Is the data that my air conditioning is collecting, is that personally identifiable information? Let's see what an air conditioner may know about me. Well, it must have three sensors to function if it's an, we need a temperature sensor so that we can regulate up or down whether we should heat or whether we should cool. We need a carbon dioxide sensor so that the air inside will not be too bad, and we need a humidity sensor also so that we don't feel super dry or super humid. And what can we learn from this data? Well, we can learn since a person is expelling both temperature and carbon dioxide and humidity, we can see where, when people come home, we can see how many people are in the room or in the house. We can see where they are. We can see when they shower, there's a very, very interesting peak when people shower. We can see whether they're sleeping. We can see when they are working out on their indoor treadmill. We can also see when they are having sex, how many people that are involved and in what room. So I would argue that looking back at what is personally identifiable information, all the data that your air conditioning is collecting on you will be regarded as personally identifiable information and therefore is data that is included under the GDPR. Yeah. I just put that there. So if you're going to look into what your own IT system is doing at the moment to see whether or not your GDPR is compliant, you first need to know what privacy data does your project handle at the moment. And it turns out to be kind of hard for very many people to do if you have a legacy system, for example. But you can try by starting to do an inventory about what kind of data your system is currently collecting on people, what you have in your mailboxes or whatever, depending on what kind of company you are. You have to know, yeah, you have to know your system, what it does. You have to know how it's supposed to work. If it does work in that way, then you also have to apply a hacker mindset and try to break it and see whether it actually, whether side channels or whether it actually works the way it's supposed to and only that way. And if you find out that this kind of assessment is kind of hard to do, well, there's a very simple solution. Just throw everything away and start over. Because if you don't have these things in the bag, it's very, very hard to become compliant. But if you do have these things in the bag, it is easy to be compliant. Next question to ask yourself is how do we ensure privacy by design? Who can access it? And why? And can we limit the amount of data we keep? And I think the two first questions, I don't know if anyone here have heard about this journalist that was using Google Docs to write an article about violations against wildlife. She was blocked from using her work tool, Google Docs. They said that while there's a violation of terms and conditions.  But it raises a very interesting question. Why did Google go through her data in the first place? Well, of course, there's not a person doing this, but this is automatically happening. This is a design paradigm that I would call privacy invasion by design. So that you intentionally give the company that is owning the software the possibility to automatically read what anyone is putting into the system. Another municipality in Sweden, Gothenburg, where I come from, they were doing a rollout of Office 365 to tens of thousands of employees. The problem is that they hadn't told the information security people about this, and they pulled the emergency brake and said, stop, stop, stop, stop, stop. The Microsoft Office 365 is not designed with privacy by design, but anyone who has access, has high privilege within Microsoft, can read sensitive data about the citizens of Gothenburg, and that's not acceptable to them. So these two examples are systems that are made with that design paradigm. And there are obviously many nice things about keeping a lot of data. You can do a lot of quantitative analysis. But what can also happen is, of course, that if an American company has the possibility of reading the data, that means that the company can be subpoenaed to give out that data, and that will break other laws, like secrecy laws in Sweden about citizens. If you're using this kind of design paradigm, you will also have a lot more data to protect and to ensure that it's not actually being used in a bad way. This is the design paradigm that we've been living under for a long time, saying that data is a new oil. On the other side, we have systems like Signal Messaging App, which I think many of the people at this conference is using. I use it every day, basically. And here we treat data as toxic waste, and almost everything is thrown away. Signal knows two pieces of information about me, basically, when I signed up and when I sent my last message. They don't know to whom. They don't know the content. They don't keep any kind of metadata about anything. This makes them virtually immune towards subpoenas from the American state. But that also makes them not being able to collaborate in fighting crimes, which obviously is something that you have to think about. But one good thing about this is also that since you don't have data, that data can't be compromised. It can't be taken over by hackers, and therefore this will be GDPR compliance kind of by design. So over to the question of informed consent. I like to think of end-user license agreements that we are used to, the ones that we simply click I accept. They don't really work under the GDPR. And I think of them in a way like martial arts versus assault. When you are doing martial arts, you have a limited scope and a limited of in time and space where you're allowed to beat someone up. When that limited scope is over, you do not have any rights at all to fight that person in any way. And in the same way under the GDPR, we are allowed to give away our personally identifiable information to another entity for a limited scope in time and space. And we have the right to revoke those. We have the right, yeah, because they are basically ours. So even if someone is a boxer, they don't have the right to beat someone up in the streets. Or even if someone is a boxer, they don't have it coming if they get mugged. In the GDPR, the kind of data that we do collect under consent and after we have been asking ourselves what do we really need and what do we really want, we have to protect it. We cannot claim that we didn't know anymore. And how do we do that? Well, it's easy. Encrypt all the things. My last question is, will any of this even matter? Will the law be circumvented anyway? I don't know. I think that the Keybridge Analytica scandal came at a very, very good time. Because now it's on the top of the mind of very many people that privacy data, when used wrongly, can be used in a very, very bad way. So I hope that that means that what will basically happen is that, since this is on the top of people's mind, people will care in the same way that people care about that they don't want to die when they're taking the boat. They also don't want their privacy data to be used for nefarious purposes. So I really hope that I am right about thinking that the GDPR is awesome and that the GDPR is going to be a part of the solution for making the IT business a little bit more secure and safe. Thank you. Well, thank you. Are there any questions? I think the implications for businesses are something we are looking forward to as private persons and so on. But what does it mean for open groups? Like you have a topic group and you have a mailing list and you have a website and so on. Basically, this applies there too. Do I have to shut down these services or what's about third party services? Like I have a third party tool that I use and so on. Is there already something that can be said about it? Well, I think it's a good idea to simply do an inventory about what you have, what your system actually looks like. And, you know, it's a very simple thing. Just start with a checklist of what are we doing? What do we need this thing here? When was the last time that we asked people on this mailing list whether they wanted to be in there? Maybe we should ask people to opt out or maybe we should even say opt in in order to stay on the list, for example. That said, I don't think that or I sincerely hope that open groups are not going to be the first ones to be fined. Also, simply because there is no money to find for. We don't know. More questions. You were talking about the feedback loop because people don't want to buy and how to improve security on ships. What do you think about the difference in the feedback loop regarding security for people and for technologists? Normal people think, okay, I'm writing and set measures to something. I don't care. I use it. And technologists think differently. Do you think this is a problem that the feedback loop does not work for normal people? I'm not fully sure. I do not understand the question, actually. I'm sorry. The feedback loop is easy to understand with ships and I don't want to die. But security and protection of my personal data, there are many customers of services like chat systems and so on that don't care about it. So we have a feedback loop for the customers, what they think and how they react. We have a feedback loop for politics and for technic people, affinity people like us. So there are three different loops and all react differently. So how do we want to bring this together? Well, I think that... Well, I don't know. I don't have to know everything. I'm sorry. We are all different. We all react in different ways, obviously. And I'm also guilty of going into the fallacy as a security person to think that... Because I think that entering into encryption is the most important feature of any kind of product, then naturally everybody else will think that too. And then all of a sudden it turns out that... Why?  I think that it's important that we security people collaborate more with user experience and that we throw away in the bin the fallacy that security and usability are things that don't go together. I don't know if that was an answer, but there was another question, yeah, there. Good evening. Until this moment I didn't know it came, or it's planned, this new policy of the data regulation. I have many questions we can talk here another two hours. But a small question and answer is possible. How long is prepared this new policy regulation by EU? How many years or how long is planned? How long they have been planning it? Well, the old legislation, the old data protection regulation is from 1994 I think, something like that. And since then there has been a lot of things happening. I don't know, but it has been the legislation in Europe for the past two years, but no one has been fined for it. The deadline is in a few weeks. The deadline is in a few weeks indeed. I have a lot of questions. I'd love to speak to you afterwards and answer any other questions. So, more questions. Good evening. I'm an old IT guy and I'm looking in the IT area for the hype of storing the data in the cloud. Big companies are offering us all features to store our data in the cloud. Office 365 you mentioned in your presentation. What do you think about it? I think in the US they all have no problem with this, but I see big problems here in Germany and in Europe for this business. Well, the privacy law that precedes the GDPR, it stated that the one who is collecting the data is the one who is responsible for it being stored securely. And then after this regulation, the legislation was done, we migrated everything into the cloud, meaning that the ones who had the legal obligation to secure the data were the ones who were oblivious of the way it was secured because they had been giving over that kind of control to the hosting providers. In the new GDPR, this responsibility is shared between the one who collects the data and the one who is storing the data. Was that some kind of answer to your question? Yes, but it's not directly attached to the GDPR law now, but it's the overall view of storing data in the cloud. If you store your data in a cloud, in a cloud provider, he is located in the US, I think the US government has access to your data. Yes, so any kind of system that is not designed with privacy designed in mind, or privacy by design in mind, or that doesn't allow for privacy by design to happen, I think is a very big problem. And we don't know yet whether or not these systems that are not designed with privacy by design in mind, but by privacy invasion by design in mind, whether they are going to be even legal or not. I think that they are going to be legal because these companies are kind of big and have a lot of lobby money. But I also think that we are such an innovative community and because we don't have to work with pre-certifications, but we can just try things and see if it works. We're using the patchable agile paradigm of security. We can just try something and see what happens and many of these systems will actually be very, very good. So I think that even though things like Google Docs and Office 365 will still be there and they will still be very lucrative to use because it might be more usable, for example, there is still a possibility for anyone who does care about privacy to actually create systems where you have a hosting provider and the hosting provider knows nothing about your data. There are lots of these systems. We implement them every day and they are also in the cloud. They are also on someone else's computer, but that someone else doesn't have access. First, thank you for the talk. I really enjoyed that. Thank you. I especially like the feedback loop and the example with the ship at the beginning. The GDPR is the regulation, so it's a law. So there are basically two ways to tackle that for companies. One is IT, technology, encryption, whatever, hosting your own data center. The other one is contracts. So if I have a contract with my cloud provider and the cloud provider can agree to certain terms, it's perfectly fine that I store customer data in the cloud if the cloud provider is not allowed to access the data. So if the cloud provider breaks the contract, I cannot be responsible for that. But the question is the two venues, IT versus contracts, do you have any hunch on which way it will go? So will it all be like contracts will be different, but IT stays the same? Or will, you know, really work more money, go towards good privacy in IT? Are you saying that, okay, so we have systems that are not designed with privacy by design. And these systems still have a contract saying, we will not look at your data. So there is no nothing that is technically prohibiting them from doing it, but we just have their pionierie rembord. They just promise that, like, they're not going to do this. We promise. What do I think? Since I'm a security geek, I will of course think that everybody will think that end-to-end encryption is the only way to go and that we will stop creating systems that gives people the possibility of unauthorized access so that we don't have to trust people's words, that we can assume breach and so on. Of course that's what I think, of course that's what I'm hoping because I'm an optimist. Just one last word. I think our job as IT specialists is to show companies that the cheaper way is to make it really secure. Because in case of, you said signal, if they get a data breach, they couldn't care less. But if other companies get a data breach, contracts don't help. And then it could potentially get expensive. I think that signal would care if they would have a data breach. But they are thinking in advance and they also have processes in place to mitigate when there is a potential... That's true, but GDPR-wise they wouldn't care. Actually I wanted to come back to your question concerning the cloud topic. So I would argue that it's actually a lot easier to comply with GDPR if you rely on a cloud system because imagine you want to run let's say a multinational company and you have customer data in Russia, China, Germany, wherever. Then it's actually a lot easier if you have a cloud provider that has data sets that are separated instead of building and running your own on-premise system in all these countries. So would you agree that the cloud helps or do you see it's a threat to GDPR? I always use the cloud. I think that the cloud is here to stay basically and it makes a lot of sense to make that people that are specialists from my experience most programmers aren't very interested in making systems administration and why should you have people be generalists and do things that they think are boring when they can do things that they think are fun. So I think that the cloud enables very many people to focus on what they like so that cloud providers can do this thing that they nerd out about and people that do products can do what they nerd out about. I'm pro-cloud with primacy by design in mind. No more questions. I have more candies there. But you don't get two candies. Is it not cloud as design? I will formulate my question. When we talk about Google, how Google used the data is not cloud as a design to use these places to access this data as an next stepping stone in extracting data about people. So somebody had a great idea in Google Office. We make our services, we make smartphones, we make Gmail, etc. and then we say we need to have a diesel or a Sprit. So we use these cloud services and from these cloud services we use this data for analysis. So are you saying... Yeah, analysis on design. Are you saying that there is nothing that technically prohibits a service like Google Docs from extracting industrial, from doing industrial espionage? Exactly. Yes. I'm definitely not saying that Google is doing that. I am saying that I have heard of companies that have decided against using this kind of system because of the possibility that they're not technically prohibited from doing industrial espionage. Yes. Will GDPR make data more valuable? Well, I think that this paradigm of data is a new oil, collect everything just in case and it will be what could possibly go wrong if we collect all these things and we sell them to a third party, whatever. Well, anecdotally, I've heard very much about how having so much data that you're collecting just in case you might need it will instead inhibit you from doing the interesting machine learning that you actually wanted to do in the first place with this data in the new oil paradigm. So if you're actually going through the privacy impact assessment first and you see what do we really want to know, how can we really find these things out? We may find out that while this quantitative assessment maybe wasn't what we wanted to do in the first place, maybe we want to do more interviews and then you end up doing a better analysis on the people who are using your product but at the same time you're also not invading their privacy. Also, if you're actually looking at what is my research question and collect that kind of data, then you might actually not end up with a hoard... You won't hoard data anymore but you will actually collect the data that you need and you will actually develop the minimally viable product that you wanted to do in the first place. So, maybe?


Hello and welcome to this presentation of the STM-32H7 hash processor. The hash peripheral is in charge of efficient computing of the message digest. A digest is a fixed-length value computed from an input message. A digest is unique. It is virtually impossible to find two messages with the same digest. The original message cannot be retrieved from its digest. Hash digests and hash-based message authentication code or HMAC are widely used in communications since they are used to guarantee the integrity and authentication of a transfer. The hash processor supports widely used hash functions, including message digest 5 or MD5, secure hash algorithm or SHA1, and the more recent SHA2 with its 224 and 256-bit digest length versions. A hash can also be generated with a secret key to produce a message authentication code or MAC. The processor supports bit, byte, and half-word swapping. It also supports automatic padding of input data for block alignment. The processor can be used in conjunction with the DMA for automatic processor feeding. All supported hash functions work on 512-bit blocks of data. The input message is split as many times as needed to feed the hash processor. Subsequent blocks are computed sequentially. MD5 is the less robust version with only a 128-bit digest. The SHA standard has two versions, SHA1 and the more recent SHA2 with its 224 and 256-bit digest length versions. The hash-based message authentication code or HMAC is used to authenticate messages and verify their integrity. The HMAC function consists of two nested hash functions with a secret key that is shared by the sender and the receiver. The hash function involved in the HMAC computation can be any one supported by the peripheral. MD5, SHA1 or SHA2. The hash processor complies with the international standards for secure hash algorithms or SHA, message digest algorithms or MD5, and for message authentication code or MAC. This simplified block diagram of the hash processor shows the basic data flow and control modules. The hash processor processes 512-bit data blocks and generates digest of up to 256 bits depending on the algorithm. Input data may be swapped before entering the core unit where they will be processed to generate a simple hash or a message authentication code or MAC. When interrupt in the nested vector interrupt controller or NVIC is triggered when a hash digest has been successfully calculated or when the hash processor is ready to accept a new block of data. Indirect memory access or DMA mode requests are generated internally for incoming data. The DMA channel must be configured in memory to peripheral mode with a data size equal to 512 bits. Sometimes it takes to process a single block of data depending on the chosen algorithms. HCLK is the CPU clock and can go as high as 216 MHz. Note that the main benefit of using a hardware accelerator is to increase speed and save power compared to a full software implementation of the hash functions. Here is an overview of the status of the hash processor in each of the low power modes. Hash operations are not possible when the device is in stop mode. This is a list of peripherals related to the hash processor. Please refer to crypt peripheral trainings if you want to know more about cryptographic engines. Refer to training on the DMA peripheral for information on how to configure the hash channel. For more details, please refer to this user manual available on our website.


This is the GI Joe classified series target exclusive Cobra Island Baroness with Cobra coil motorcycle this set was introduced this year in 2020 and has been extremely hard to find Even though this set should not be any more scarce than the other Cobra Island figures has been very hard to find due to poor Distribution by both Hasbro and Target special Thanks to Chris Clements for keeping a close eye on the inventory tracking websites and helping me secure this one Let's take a look at the box that the figure and vehicle were packaged in but first I'll note the backdrop you see here was an insert in the box So I'll place it back in the box so you can get an idea of what that looks like here is the box with that backdrop Reinserted so this is what it would look like on target shelves with the figure and vehicle inside of course You can see the toys themselves are in this Vacuum formed protector and there are a few bits still in there that I haven't taken out yet that I don't Display with the figure. I will take those out though so you can look at them for this review There's the GI Joe logo with classified series Baroness with Cobra coil and coil is an acronym I was looking on this box to see if I could find out what coil stands for but I don't see it anywhere on this corner We have special missions Cobra Island and this is the set that is exclusive to target on the other side We have some gorgeous artwork with the Baroness on the motorcycle and then the Baroness herself on the side of the box Beautiful artwork. I love this on the back of the box We have this overhead view of Cobra Island and this is standard for all of these Cobra Island Exclusive sets the individual packed figures also have this map on the back This is different from the map that appeared in the 80s comic book Even so it looks pretty cool And it gives you an idea of what Cobra Island looks like and how it's set up Really nicely done on the top of the box We have the Cobra emblem with a red background that classified series logo again And we can see this is number 13 in that series on the other side We see that number 13 again, and we have these icons Which you can go to GI Joe comm and look up and these correspond with specialties for the character This one is intelligence level four. This is light weapons level one This is psy ops level three and this is disguise level four The bottom of the box just has the barcode and lots of information in several different languages I'm going to pull that backdrop out again because I think it looks really nice And then we will look at the motorcycle and the figure Let's look at the coil motorcycle and the first thing I'll say about it is it feels substantial The plastic does not feel cheap. It doesn't feel too hollow though. It's not perfectly solid, but this is well done It's well constructed. It does not feel flimsy in any way I will point out there are some exposed screw holes on this side So the other side will be your display side There is a green tint toward the lower part of the windshield. That's a nice color gradient Well done It has some green gauges and cobra emblems I will point out these handlebars are articulated the handlebars are individually on a ball joint So they can adjust that windshield will also adjust a little bit These handlebars will move a bit so that will compensate for the figure's wrist articulation So you can get her to hold it in more positions and that's helpful Those handlebars are also linked to the front fork steering My opinion it's a great looking motorcycle and the black red and silver color scheme are perfect for a cobra motorcycle Looks like it has a little scratch on some of the red paint right out of the box So another good reason for this to be the display side There are foot pegs one on each side to secure the figure on and there is a kickstand But the bike will stand up without the kickstand and I like that that will help you get more writing poses out of it The figure has holes on her heels and those should fit on these foot pegs. They fit reasonably well Maybe not the best. I'm kind of have to pose the figure a bit before you get it on there the figure is really more going to be secured by the handlebars and the Handlebar once you get it on the figure's hand, which can be a little bit of an ordeal But we can do it once you get the handlebar on the figure's hand. That's not going to come off very easily So there you have the Baroness on the motorcycle or she can put her feet on these back pedals here For a more, you know Forward go fast look. Let's take a look at the Baroness's accessories and she comes with a significant number of them She has two of these rifles or submachine guns or whatever. They are they look Very close to the same, but they have pegs pegs on opposite sides And that's because they can be used with the vehicle. She can either grip them and use them as hand-held weapons or They can plug into these holes on the side of the coil motorcycle adding some extra firepower So that is pretty cool. She could also carry one on her back She has a hole on her back, but I think this is much better. It adds some firepower to her ride She has two gold pistols pretty well sculpted nice details They are both the same just two copies of the same pistol and she can holster these on the figure There is this web belt that is a separate piece It's not intended to be removable, but it has a really cool red Cobra emblem right on the center and in the back She has two holsters So she can holster each of those pistols like so and they fit in pretty well And they are ready for her to draw from the back. So that is a nice Bonus feature. I like it when the figure can holster the weapons Destro also came with a gold pistol. As you can see, it's not the same gold pistol It's it's definitely different and it's also a bit shinier I'd kind of like the Baroness's pistol to be in that shinier gold plastic next she has this dagger with a Gold Cobra head on it really cool looking very tiny intricate details Very well done and she has a sheath for that this separate piece on her leg Again, I doesn't look like it's intended to be removable, but the knife Will fit in there and of course we want the knife in there with the Cobra head facing forward I want to see that really sweet detail there So she's got several holsters for her weapons next she has this Cobra coiled laser blaster That appears to be what this is this is a laser blaster But it's all coiled up like a Cobra and it's intended to coil around her arm Which is really innovative and unique way to have a figure hold a weapon So it can be a little bit tricky to get on the arm and there's not really a grip I guess you can try to put her hand around the The Cobra coil here in the front, but that's how it's supposed to work. She has this Coiled Cobra that shoots lasers out of its fanged mouse. That's Interesting very science fiction, but also kind of cool and it looks nice It's very very well sculpted with lots of cool details.  It has no other colors It has no other paint applications, but it is nicely sculpted with some fangs on the visor Really well done and the Baroness can wear this helmet sort of this is an alternate head You can see the hole in there for the neck post You should be able to take off the primary head and put this helmet head in its place Now I'm not gonna try that because it is possible to break the neck post on these figures And that's not something I'm going to risk with a figure that was so hard for me to find in this case I will just show you the helmet rather than put it on the figure Let's do a quick compare contrast between the classified Baroness and the 1984 three and three-quarter inch Baroness And a lot of the details from the original figure are carried over to the classified figure The black uniform the red cobra emblem on her chest The glasses even some of the ridges on the legs are the same on the classified figure The classified figure has a lot more detail as it should because they have the scale to add more detail It also has a couple colors other than black and red as we shall see momentarily these classified figures have pretty good articulation This one has a ball-jointed head But she has a hairpiece that hairpiece though does not really get in the way very much of that head movement Good range of motion on that good range of motion on the shoulder as well She does have articulation at the elbow, but I'd like to see a bit more articulation at the elbow I'd like to see more of an elbow bend. She has swivels at the wrist Doesn't look like she has hinges at the wrist just swivels I guess there is a little bit of up-and-down motion on the right wrist There is a cut just above her ribcage, but you can't get much movement out of that There is more movement at the hip if you want to get her body turned That's really where you're going to get the articulation for that There is an excellent leg split There is movement on the legs at the thigh forward really good Back not so much. It tends to flare out to the side a bit. There is a cut at the thigh So movement at the thigh there are double-jointed knees and she has hinged and Rocker ankles. Let's look at the figure itself. This head sculpt is amazing. It's very lifelike very natural She has a black hairpiece in soft plastic and that looks great She has glasses and those glasses are a separate piece, but they are not removable They are black and gold horn rim glasses and they have lenses. That is amazing That's a really nice touch. Look at the subtlety of that smile with her lipstick You can just barely see her teeth, but her teeth are painted in That's just too good. She has armor on her shoulders and on the left shoulder. It looks like a cobra head That's really cool. She has this black chest plate and a red cobra emblem that is molded in and painted on her chest That's not just a paint application. That's in the mold on her upper arms and on her midsection There's just a little bit of dark gray or pewter paint. It's very subtle But that's all you need just to make the details pop a little bit with this gorgeous black uniform You don't want anything less subtle than that.  She has that web belt that we looked at a moment ago It is a separate piece, but it doesn't appear to be removable It has a red cobra emblem right in the center at the buckle It has some pouches and of course it has those holsters in the back Really well done. There's more of that pewter color paint on her legs and on her waist piece There's that separate part for the knife sheath that goes around her left leg And then there's the leg armor with some knee pads and some armor plate on her thighs and on her shins Looks really good And there's even a spot of gold paint on her ankles these little rings on her ankles and she has Pointed boots in a lot of ways this bareness figure is the anti scarlet the scarlet figure was okay But it had some problems with some of the accessories wanting to fall apart and with the colors being a little too busy With the bareness you have the right colors in the right proportions. You have excellent accessories You have excellent sculpting. It's about as good as you can do a six inch gi Joe figure Would I recommend this figure if you have a classified? Destro I would highly recommend looking into a classified bareness because they look so great together I mean they look like they were made for each other. I mean just look at them together That's one of the travesties about this being a target exclusive figure Some people will have a hard time getting it But if you can get it without paying scalper prices, I would recommend looking into it some collectors don't like the motorcycle I like the motorcycle just fine. This looks like something the bareness would ride These classified figures are not all created equal. There are some you could pass on without missing much But this is not one of them. There is a reason people are going crazy for this figure There's a reason why people are trying so hard to find this figure even though it's been very difficult to find at retail Maybe you can skip second versions of Destro or second versions of roadblock But this one is one not to miss. I just hope you can find it. Good luck That was my review of the gi Joe classified series bareness and the coil cycle. I hope you enjoyed it I usually do vintage gi Joe toy reviews and I usually do them once a week You can find me on social media on Facebook and Twitter and I have a website HCC 788.com. I also have patreon which helps keep this show going Thanks to all the names you see on the screen right now You can get some special perks there like a sketch or early access to reviews or a secret code book So you can decode the messages you sometimes see in my videos. Thanks for watching It's time to get away from Cobra and back to gi Joe. So until next time remember only gi Joe is gi Joe

Chemistry Lab is different from most other courses. Here you gain new knowledge by doing things, not just reading about them. You'll spend much of your time in Chemistry Lab working with equipment and techniques that are new to you. They can be dangerous if you don't adhere to strict safety procedures. But if you start with safety by following the rules, paying attention, and using common sense, you can work with confidence that you'll be safe in the Chemistry Laboratory. And you can have fun at the same time. Handling chemicals safely means following rules designed to keep them from contacting your skin and eyes or someone else's. One important safety rule is always use small containers that you can control easily. Ignoring this rule can cause accidents. If you have an accident, always inform your teacher. Pouring from small containers is far safer. Accidents can also happen when mixing chemicals. Is this OK? Looks fine. You can go ahead and get started. Thank you. To be safe, only mix chemicals when your teacher says to. Read the instructions for the experiment all the way through first before doing anything. Read and reread labels before use to make sure you've got the right chemicals. Note the concentration and the hazard warning. Accidents can happen when the wrong chemicals are mixed together or when the right chemicals are mixed together in the wrong way. Make sure to follow your instructions exactly. For example, suppose you have to dilute concentrated sulfuric acid with water. You might think you could mix them together any way you wish. But there's an important rule for diluting concentrated sulfuric or phosphoric acid that should always be followed. Add the acid to the water, never the reverse. Remember it by the initials AA, add acid. Watch what happens when you don't follow this rule. This is water added to acid. The acid boils, and it can splash out of the beaker. When acid and water are mixed correctly, there's less danger. Acid is poured from a graduated cylinder or beaker down a stirring rod into the water. Whenever you work with chemicals, there's a chance of spills. A work tray under your setup will help contain them. Always move carefully when handling chemicals. Keep coin top stoppers between your fingers, not on the bench where they can pick up contaminants. Hold bottles with your hand over the label and replace stoppers immediately. Covering the label keeps drips from blurring it or getting on your hands. Set bottles out of the way when you're finished so they won't get knocked to the floor. When handling chemicals, always keep them away from your face. Never taste anything to see what it is and don't touch it or smell it directly from the bottle either. Small amounts of some chemicals, even vapors, can harm your eyes, mouth, and nasal membranes. There's a safe way to smell a chemical indirectly if your teacher gives you permission. Hold it away from your face and waft the vapors to your nose. That way you won't get a strong whiff of them directly. Certain chemicals give off vapors. They're called volatile chemicals. You should work with harmful volatiles under a fume hood. Your teacher will tell you what these chemicals are. Chemicals should be kept pure and uncontaminated. One way to prevent contamination is to use only clean glassware. Another way is to only pour out of a reagent bottle. Never pour anything back in. Even excess chemicals you haven't used. It's better to waste the excess than to risk contaminating the entire bottle with particles from around the lab. After measuring out a reagent, you'll often have something left over. Instead of pouring it back in the reagent bottle, dispose of it in the proper waste container. When drawing out chemicals with a pipette, don't use your mouth. Use a bulb or pipette. You can collect the exact amount you need and never have to come in contact with it. At some point in your laboratory work, you'll probably spill something. You should report spills immediately. Stay away from the spilled chemical and let your teacher clean it up. To keep a large spill from spreading, it's barricaded with an absorbent material, such as kitty litter. It's then either mopped up or covered over completely with the absorbent. The absorbent and chemical can be swept up with a broom. What's done with the residue depends on the type of chemical it contains. Your lab should have a container for each type of waste. Don't throw waste chemicals down the sink unless your teacher says it's all right. Waste paper that's not contaminated by chemicals goes in a conventional trash can. And broken glassware goes into a separate container. The last chemical handling safety rule to keep in mind is to clean up when finished. Glassware should be thoroughly scrubbed and rinsed so it's as clean as possible for the next experiment. Liquid puddles or powders left behind on a lab bench can get on the next person's clothing or skin. Wipe them up thoroughly and throw the paper towels away in the proper container. And clean chemicals off your hands before leaving. There may be invisible chemical residues that could damage your skin or contaminate your food the next time you eat. Work with small containers. Mix chemicals only when your teacher says to. Read and reread chemical labels. Read instructions all the way through first. Use a work tray if your lab has them. Move carefully and deliberately when handling chemicals. Add concentrated sulfuric or phosphoric acid to water. Hold coin top stoppers between your fingers while pouring. Hold bottles with your hand over the label. Replace stoppers immediately. Keep chemicals away from your face. Work with harmful volatile chemicals under a hood. Keep chemicals as pure and uncontaminated as possible. Draw out chemicals with a pipette filler never by mouth. Notify your teacher to clean up spills. Put waste in the proper container. Clean up when finished. The main heat source in most chemistry labs is the Bunsen burner. It produces an open gas flame burning at a high temperature. There's always the danger of an accident if it's not used properly. For example, it should never be used to heat volatile organic liquids that give off flammable vapors. These substances should be heated in a heating mantle or a steam bath in a hood. But for most other substances, a Bunsen burner is an ideal heat source when used properly. There are several types of Bunsen burners, but they all have the same basic parts. The gas comes from an outlet on the lab bench. A rubber hose fits over the tip and over a similar fitting on the Bunsen burner. Most burners have a valve at the bottom to control the flow of gas. Air inlets control the amount of oxygen in the flame. A wing top can be placed on the burner to spread the flame out. There are several important rules to follow to use a Bunsen burner safely. First, check the gas hose for cracks. If you see any, get a new hose. Make sure the hose fits securely on the gas valve and on the Bunsen burner. The gas valve at the bottom of the burner should be open. You can light a Bunsen burner with a striker or a match. Open the gas line valve and light the burner. If the flame's properly adjusted, you can place the burner under your setup. When using a match, strike it away from you. Turn the gas on after the match is burning. That way, gas won't escape while you're striking the match. Light the gas from the side so the match isn't blown out. A yellow flame is too cool. Opening the air holes lets in more oxygen for combustion. Adjust the bottom valve if the flame is too large or small. The flame should be blue with a lighter inner cone. The tip of the inner cone is the hottest part of the flame. If the flame begins to sputter or flare, turn the gas off immediately. Also turn the gas off immediately if the flame goes out. Unburned gas escaping into the room could ignite and cause an explosion.  Cracks or stars and glassware are dangerous. They can break open when it's heated. So before you heat any glassware, check it carefully for cracks or stars. Flat-bottomed containers are normally heated on a wire screen on a ring stand. Erlenmeyer flasks and other narrow-necked containers should be secured to the stand with a clamp. Test tubes can be heated in a water bath. The water bath transfers heat slowly and evenly to the test tube and helps keep it from boiling over. You can also heat a test tube directly in the flame. Hold it at an angle while moving it back and forth to distribute the heat evenly. Aim it away from yourself and your neighbors in case it boils over. Only heat containers with openings. A boiling liquid changes to gas, which must be able to escape. Gas can't escape from a closed container, and the pressure that builds up can burst it. Be extra careful when working with heated equipment. Hold hot glassware in beaker tongs, never your hands. Remember that the wire screen and ring stand are also hot. If you don't have tongs, protect your hands with gloves designed for hot glassware. Keep them away from the flame. Handle everything as if it's hot if you've been using a Bunsen burner. Glass and metal look the same when hot as they do when they're cold. Heat volatile organics in a heating mantle or a steam bath in a hood, not over a Bunsen burner. Check the gas hose for cracks. Make sure the hose fits securely on the gas valve and Bunsen burner fittings. Stand back from the burner while lighting it. Strike matches away from you. Turn on the gas after lighting the match.  Check glassware for stars or cracks. Clamp narrow-necked containers to the ring stand. Move test tubes back and forth through the flame at an angle while heating. Don't heat closed containers. Hold hot glassware in beaker tongs or hot mitts. Thermometers are one of the most important tools in the chemistry laboratory. They're easy to use, but since they're usually made of glass, they have to be handled properly. One common misconception is that lab thermometers have to be shaken down like medical thermometers. Shaking is totally unnecessary, and it can be dangerous. The liquid inside can move freely up and down on its own without shaking. Some lab reactions take place at higher temperatures than an alcohol or mercury thermometer can stand. The temperature of oxidation in a Bunsen burner flame is around 600 degrees Celsius. That high a temperature will vaporize the liquid inside. The resulting pressure will break the glass. But most lab experiments are conducted at temperatures from 120 degrees Celsius down to minus 20 degrees. And for that range, either a mercury thermometer or an alcohol thermometer is suitable. No matter which type you use, always treat it carefully. When you're finished with it, set it down where it will be safe. Lay it away from the edge of the bench on a wire screen or towel so it can't roll off. When a thermometer breaks, the glass and any liquid that spills out must be cleaned up and disposed of properly. This is a job for your teacher. Glass fragments can be swept up. If any alcohol happens to escape from the glass, it can be wiped up with a paper towel. Cleaning up a broken mercury thermometer is more difficult and also a job for your teacher. Mercury is poisonous, and it won't soak into a paper towel. Mercury vapors also can escape into the air. If you work with mercury thermometers, your lab may be equipped with a mercury cleanup kit or sponge. The kit and broken glass should be disposed of in the proper container. Don't shake thermometers. Use thermometers only in the temperature range they're suited for. Lay thermometers down on a towel or a wire screen to cool away from the edge of the bench. Let your teacher clean up broken thermometers. The most common lab injuries are cuts from broken glass, especially glass tubing. A typical accident comes from using too much force to push a tube through the hole in the stopper. One way to avoid this kind of accident is to use an inserter. First, dip the Teflon tip in a glass lubricant such as glycerin. Then push it through the stopper. Remove the tip and slide the tubing through the hollow inserter shaft. Removing the shaft leaves the tubing behind. Make sure to wash the lubricant off the tubing and stopper before using them. And replace the Teflon tip so it doesn't get lost. To remove the tubing, take out the tip and lubricate the end of the hollow shaft. Push it through the stopper hole around the tubing. Then slide the tubing out through the shaft and remove the inserter. Remember to wash the lubricant off before returning the stopper and tubing to storage. And don't forget to replace the tip. If you don't have an inserter, lubricate the tubing instead. And protect your hands with leather gloves. Push the tubing gently through, rotate it if there's any resistance. Use the same care when removing it. And don't forget to wash off the lubricant. Use an inserter to place glass tubing in a stopper or remove it. Or lubricate the tubing and protect your hands with leather gloves. A centrifuge spins mixtures around in test tubes to separate solids from liquids. The solids move out toward the bottom of the tubes and the liquid stays on top. When the test tubes inside aren't evenly distributed, the centrifuge is unbalanced. It vibrates like a washing machine with an unbalanced load. If the vibration is bad enough, it can fall off the bench top. To prevent vibration, a centrifuge must be balanced. If you're only centrifuging one test tube, place another one opposite it with an equal amount of water. Once the centrifuge is balanced, you can turn it on. When it's finished, turn it off. Then wait till it stops spinning on its own. Never try to stop a centrifuge with your hand. Place equally filled test tubes in a centrifuge to balance it. Don't try to stop the spinning with your hand. A safe lab session starts with proper clothes. You must wear clothing and equipment that will protect you from chemicals and flames, and at the same time, stay out of your way. For example, sleeves that are too loose can drag through a chemical puddle or knock things over. The wrong material is also dangerous, as this mannequin demonstrates. Fuzzy sweaters or filmy fabrics can easily catch on fire. Synthetics such as polyester melt when they burn and stick to the skin. The right kind of clothing includes sleeves and shirts that fit fairly close, but aren't too tight to restrict movement. And fabrics made of sturdy cotton or wool that won't melt and stick to your skin.  But you should still wear older clothes underneath in case any chemicals get past the apron. Legs are vulnerable to chemical splashes and broken glass if you drop something. So long pants or a long skirt should be worn to protect them. Open shoes can't protect your feet from spills. Closed leather shoes are much better. And shoes made of cloth or woven material can absorb spills and hold harmful chemicals against your skin. Besides wearing the right clothes, there are other precautions you should take to avoid accidents. Tie up loose, long hair. It could knock something over or even catch fire. Remove rings and watches. They can trap corrosive chemicals against your skin. And the chemicals can damage your jewelry.  Don't wear contact lenses in lab. They may trap chemical vapors against your eyes. If that happens, your eyelids may go into spasms that make it impossible to remove the lenses and wash out the chemical. Always wear goggles with side shields to completely protect your eyes, even if you're already wearing glasses. And finally, protect your hands. Never use bare hands with concentrated acids, bases, or other reactive chemicals, such as concentrated hydrogen peroxide. Your teacher will tell you what type of gloves to wear to work with these chemicals. With the right clothes and protective equipment, you can work with laboratory chemicals with confidence and safety. Don't wear extremely loose clothing. Fabrics should be sturdy and natural. Wear older clothes and cover them with a lab apron. Wear long pants or a long skirt to cover your legs. Wear closed leather shoes to protect your feet. Tie up long hair. Remove rings and watches. Take out contact lenses. Cover your eyes with goggles with side shields. Protect your hands with the right kind of gloves.  Fooling around can have disastrous consequences. You could scar yourself or others for life, even cause blindness. So the most important rule of all in the lab is no fooling around. Don't run, push, or wrestle, or even move fast. Even if you're not fooling around, accidents can happen. Wait a second. Personal belongings in the middle of aisles can trip someone. Even a job as simple as reading a burette can lead to an accident. For greatest accuracy, your eyes should be on the same level as the number you're reading. If you can't read a burette accurately, lower it down to eye level. If you can't do that, stand on a step stool. There are behavioral rules to protect you against less obvious hazards, too. Applying makeup may seem harmless enough, but chemicals and vapors and spills in the lab can contaminate it. Then when you apply it to your face, you put on the chemical, too. So keep makeup outside the lab. Eating and drinking in the lab can cause similar problems. Chemicals can contaminate your food or splash into a drink. Guys, I think it's time to go to class. It can't be. It is. Get rid of them before you come into the chemistry lab. Don't fool around in lab. Keep aisles clear of personal belongings. Stand on a step stool when you have to reach. Keep makeup in your purse. Keep food and drinks outside. In spite of safety precautions, people sometimes get careless and accidents happen. That's why a well-equipped chemistry lab has emergency equipment to take care of them. If you've cut yourself, wash the wound to remove any chemical traces. Make sure there are no pieces of glass in the cut. Dry your skin carefully so a bandage will stick. Let your teacher put the bandage on the cut. Notify your teacher whenever you have an accident. And make sure to get immediate medical attention after any injury in the lab. Chemical spills and splashes are also common lab accidents. Are you OK? My eyes. Let's go wash them out. If a chemical hits your eyes, wash them immediately in an eye wash fountain. Hold your eyes open and roll them around so the water can wash them thoroughly. You shouldn't be wearing contacts, but if you are, get them out as soon as you've given your eyes a good initial rinsing. Continue washing for at least 15 minutes. Then see a doctor immediately to check your eyes for damage. Non-corrosive chemical splashes on bare skin should be rinsed off in the lab sink with plenty of water. Spills of corrosive materials require a lot more water. Don't wait till you feel pain from the chemical. Head for the safety shower immediately. Rinse your body thoroughly as fast as possible.   Your teacher will clear the other students out of the room. Stay under the shower for at least 15 minutes. Fires are always a potential hazard in chemistry lab, especially when organic liquids are involved. Small fires in containers can often be put out by covering them.  Larger fires require a fire extinguisher. It should be operated by a teacher, not by a student. No, let's leave. If the fire is too large to control, clear out of the building. Call the fire department when you're safely outside and tell them what chemicals are involved. Clothing fires can be put out in a couple of ways, as the mannequin will demonstrate. The best way is in the safety shower. If the shower's not close by, the rule is stop, drop, and roll. The victim's weight on the fire puts some of it out, and a fire blanket gets the rest. Flames should be kept away from the victim's face. Anyone who's been burned must get medical attention immediately. Clean and dry the skin around a cup before a bandage is applied. Rinse chemicals from your eyes in the eye wash fountain. Rinse chemicals from your hands and arms with water in the sink. Remove your clothes on the way to the safety shower to rinse large spills from your body. Extinguish small fires in containers by covering them. Let your teacher use an extinguisher to put out larger fires. Put out clothing fires in the safety shower. If there's no other way to put out a clothing fire, use a fire blanket carefully to keep flames away from the face and neck. The accidents in this program may look serious, and many of them are. But don't let the potential for danger scare you away from chemistry lab. A safe, well-run chemistry lab is an interesting and rewarding learning experience. If you pay attention, use common sense, and follow the safety rules you've seen here, the chemistry laboratory can be safer than your own home.
