That is an example of central configuration, something you do not want in a large application. Of course, you don’t actually want to be playing a shitty quiz game, so thankfully a timer will move you onto the next round after about 10 seconds. Perk Pop Quiz is another application from the Perk Family and functions in a similar method as Perk TV. Another example of this anti-pattern is the webpack.config.js file, where you have this one thing that is assumed to build your entire application. Obviously, we all have super complicated applications, but I’m going to use a very simple example. It is something you use instead of import. They now have to think about “Do I import something, or do I use enhance? And things aren’t as nice anymore-something that was static, now becomes dynamic, which is another red flag for the programming model changing. So, if you design this very large application, you have think about: Do I take that super fast method that is more complicated, or do I go with hydration which is less efficient, but such a nice programming model? The way hydration works, is you server side render something, and then on the client you render it again, which means you have to load the code to render something that is already on the page, which is incredibly wasteful both in terms of loading the code and in terms of executing it.

If you know how server side rendering typically works in frameworks like React or Vue.js, what they do is a process called hydration. It is called enhance. As I mentioned before this has the central import problem. I want to give a few examples of this general idea that you want to avoid central configuration of your application at all cost, because central configuration, like having a central CSS file, makes it very hard to delete code. We at Google have come up with a solution for this, that I want to introduce to you, which I don’t think we have ever talked about. … This happens, and I think CSS is particularly famous for it. I think the CSS community is at the forefront of a revolution, because they realized this is a problem, and they created solutions like CSS-in-JS. The human is there again and they have to think about “there is static import, there is dynamic import, when do I use which?

Looking at the dependency graph, what happens it that there are still the same components, but the arrows point in the opposite direction. It could be module dependencies, it could be data dependencies, service dependencies, there are many different kinds. Obviously there can’t be one giant configuration file for all of npm. Once again, we need a pattern to emerge how to decentralize the configuration of our build process. Because with this some engineer says “Do I still need that root component? About to start my first job as a full-time software engineer at 41! As a college student, I don’t have thousands of dollars to invest or the funds to start my own business. So, my warning to you is: If you want to be more successful than Google Plus, don’t have 800KB of JS in your base bundle. The internet giants want to rule everything around you and collect as much personal information as technically possible along the way — a strategy that’s worked exceedingly well for them.

Avoid Tablets: While tablets have worked for phone farming in the past, more and more applications are phasing them out. Phone farmers must remain on the lookout for battery bloat or signs of device wear-out. The company has already been thinking about ways to simplify the process of connecting its Echo devices to other internet-connected appliances, as evidenced by the Echo Plus device it introduced in September 2017. The Echo Plus has a built-in smart-home hub that makes it possible to connect compatible products by simply saying “Alexa, discover my devices,” rather than going through the traditional set-up experience. It is, however, a manufactured device and as such will break down occasionally. You can decompress filesystem images to search for specific password files (passwd, shadow, etc) and try to break password hashes. That just wouldn’t work with hundreds of thousands of files. With that these files becomes addition-only. You can extract files from the image and search for backdoor passwords or digital certificates. When installing and configuring OpenWRT, I also downloaded the last version of the Archer C7 official firmware image provided by TP-Link and decided to analyze it.

You can find more information about binwalk in the official documentation usage page. Ideally though, you find that most natural path. These are the things that are going to go wrong when you have a lot of engineers over long periods of time. This is particular bad case of this problem, because the power of enhancing a module, of being able to make everything else in the system have a dependency on you is very powerful and very dangerous if gotten wrong. My next topic is my favorite problem in computer science-which is not naming things, although I probably gave this a bad name. It is easy to imagine that this might lead to really bad situations. That might go fine for a while, but eventually needing to know about every aspect of what some other team did somewhere in the app just doesn’t scale. Who really knows whether that still matches anything in your app?
