Just Want You To Know EP Rar __EXCLUSIVE__


We'll start by taking a look at some signs that you may want to consider leaving your job. Next, we'll talk through some of the excuses people tell themselves to stay in these unsatisfying jobs (taking them down one by one, naturally). Then we'll give you some ideas for what to do if you DO decide to quit the job you hate and do something wonderful!




Just Want You To Know EP rar



And then, in the last episode, Episode 181, we got practical. We just talked about the nitty gritty with practical stuff on how to make a book-a-day viable in your busy schedule, in your busy home. So, if you missed any of those episodes, I encourage you to go back and listen. And you can send me any questions you have about the how or why of reading a book-a-day with your students.


Yeah, I mean I think this kind of goes back to how we were talking about, people are multifaceted and complex and so this idea of priority as a singular term kind of helps me acknowledge that every yes I give is a no.


So I think this could be a really powerful question, which problem do I want to solve right now? Knowing with a confidence that I am a professional problem-solver, that is what I am as a mother. So you have everything you need. You are superbly qualified for this, which problem do you want to solve? I think this could be a really powerful question to ask ourselves in our homeschools. And I think, Kort, you mentioned doing this regularly, like a regular review of this kind of thing.


Is it possible to understand what is inside archive on the web site without full downloading?For example, I want to know where there is pdf file inside. If yes, I will download such zip/rar, if no - I'll skip it. So, is it possible to get small part of the archive and decompress folder/file structure?


For ZIP files you will want to grab all the central directory records at the end of the file. You do this by grabbing enough of the last data and look for the End of central directory record (EOCD). This should be the last 22 bytes starting with 0x06054b50 if there is no comment. This record has an offset of where the central directory will start, relative to the start of the archive. Then you make sure if you have downloaded all that data in the first grab or if you need to grab some more again. After that you just have to interpret the central directory file headers to see if there is a PDF file inside the ZIP. Info about the file format can be found on the Wikipedia page or in one of the references over there.


Doing the same for RAR files will be harder because there is no single place to grab all the meta data from. You will need to check the file header blocks that are all over the RAR. If the file has only one archived file, you can just grab the first X bytes and check that. Have a look at the RAR TechNote.txt for how to parse a RAR file.


Filip Skokan: Absolutely. It started in 2013 with myself moving to Germany actually. This was for a position in a games publishing company called ProSiebenSat Games. This company was operating a very popular gaming portal called Alaplaya that used to host a number of game titles. These were either in browser or had their own dedicated desktop launchers and even thick game clients. They all shared the login system though. The same account was used to log into the portal, to the shop, to the support center, and of course the game launchers or the game clients. The company was using Central Authentication Service protocol version 2. 0. This is a single sign- on protocol developed on Yale university, I believe somewhere in the early 2000's. It was one of the systems I ended up maintaining for the company. The company was eventually acquired and moved to Berlin, but it was the work done on it's single sign- on, and maybe even partially my engineering skills who knows, that got the group's CTO convinced I could deliver a special project for her. The project was the central single sign-on for the rest of the group's digital business. Important stuff, right?. But it had a caveat, it had to be in place quickly for the next season of a very popular reality TV show, think, Germany's Next Top Model or something like that.


Filip Skokan: Yes, absolutely. So I knew back then already that CAS was out of the question. It wouldn't support the already looming and blooming, exploding mobile application landscape. So this was early 2014, I barely knew what OAuth was, but I remember OpenID connect was fresh out the oven. So I made a POC using in-house built proprietary OpenID Connect interface. It wasn't used in the end, but it was quotes "ready". And as we were going around the demoing the work that we got, we managed to onboard more developers on the project and began making it really production ready because the CTO and the product officers and the group of the product officer, they picked it up and they liked it. So we went along with it. We were forced to make compromises though along the way. So protocol conformance went out the window, but I was so intrigued by what OpenID Connect had to offer that I started work on my own OpenID Connect libraries for NodeJS. One of those being authorization server and the other one being the relying party so that I can test my own server. Cool. As I was developing this, I stumbled upon the connect certification program which is ran by OpenID Foundation. And I immediately wanted my software to conform to it. I wanted that certification badge. I wanted it really, really, really, really bad. And I don't know if it was bugs in my software or the certification suite, but I used to be that proactive in the issue tracker to make it onto the team that managed that certification software. Now, the team composed of big names and established names in the industry, Mike Jones, Roland Hedberg, and Hans Zanbelt. I was contributing feedback automation CI to test the suite. And while I was doing all of that, I was getting pretty firm knowledge of the different specifications that it was dealing with, mainly OpenID Connect core built on top of OAuth2.0 and so on, you know drill. And from there on, it actually gets a bit blurry because it went really fast. I got introduced to Pamela Dingle as the guy who tests the tests and you know how big she is on protocols and standards. So the next thing I remember was giving a talk at Cloud Identity Summit in Chicago. It really went that fast. In there by the way, I recall meeting you for the first time. You surely don't remember.


Filip Skokan: They were really those open source projects I wanted certified and up to date with the latest specifications, the hottest draft that put me on auth0's radar because Ayth0 reached out to me, they said," Hey, you're writing OpenID Connect open source. We do identity as a service. Would you mind coming on board?" So I joined Auth0, moved back home to Czech Republic, and that relationship is still going strong today. While I'm supported by Auth0. I continue to contribute to OpenID Foundation, to the connect and FAPI Working Groups, the certification program, and of course the IETF OAuth working group, in all of those I keep up- to- date on the developments in those groups and feed that knowledge back to Auth0.


Vittorio Bertocci: Very nice. That is a great trajectory. And I like the hands-on component of it. So you have both knowledge of the protocol itself, but you also do things in concrete. So what they like to call a warrior priest, you know both sides of the house. And in fact that's what I'm hoping to learn from you today. And so I wanted to get into the main topic, which is a positioning a bit, the three acronyms that I mentioned as in of this PAR, RAR and JAR, what are those things? What problems do they solve? How they came to be? Imagine I know nothing about them, which is also reasonably accurate and explain to me what they are and why they are.


Filip Skokan: So these three, they all deal with different shortcomings in the core OAuth2.0 specification, they are really the outcome of the, I think over 10 years of OAuth2.0 being in use, the different applications OAuth was applied to over the years called for these extensions. Because when you think about it, when OAuth was conceived, the internet application landscape was rather simple, browsers were far from being secure. TLS, wasn't being adopted as much, cores wasn't the thing at all. And in general, the service providers were handling maybe one to two authentication servers at a time, a few web clients and maybe a single resource server, whereas today the landscape is completely different. So let's start with RAR then, RAR stands for the Rich Authorization Requests. It's a draft specification under the IETF OAuth Working Group. And it brings more expressive power to your authorization requests. The core OAuth2.0 authorization expressiveness is really simple, and it was designed to be simple, but in so it is also limiting, you have your scopes, maybe recently standardized resource indicators to be able to tell which resource server those scopes belong to, but that's it, you can't specify more than those two dimensions and sometimes not even that just scopes and what you're often left with is just those scopes. It's limiting there's no way to express complex authorization needs.


Filip Skokan: So what RAR does to address this is, it introduces a new authorization request parameter called authorization details, which is a JSON structure. And with JSON comes power, you have all that syntax available to you, you have your properties that can be erased, they can be nested objects and so on and so forth. And with that, you can express such a request that we have just mentioned. The specification itself does not prescribe the shapes of these requests, but it specifies how those are transmitted from the client to the authorization server, and then from the authorization server through an access token over to the resource server that I'm about to use.


Filip Skokan: JAR another pirate acronym originally came from OpenID Connect and it allows the authorization request that's being transmitted via the browser to be integrity protected, to have its origin verifiable, to be nonreputable and also optionally to be confidential so that no one but the authorization server can tell what goes over the wire. And it does so by making the authorization request a JWT and you know JWTs can be either signed or encrypted or both. 041b061a72
