Ironically, it sits in roughly the same location as the park's former Wild Mouse. Let's get the credits out of the way first. Why.?Īnd this would be one of roughly 847 Wacky Worms in Ocean City. That's right! You can buy a photo of you and/or your child on the Wacky Worm!Īh, but this Wacky Worm is special. The one on the left is motorcycles, while the one on the right is random vehicles. These two Hampton kiddie rides have been at the park since its opening in 1965. Nothing like a little conspicuous advertising on the kiddie flat to keep things fresh. I promised you every ride at the park, but I made no such guarantee about providing clever captions for each one. "Look out, dude! It's going straight for your oversized package!" Matterhorn/Musik Express/Hurricane (it had no sign, so it's hard to say which one it really is). By the way, is it just me, or does Jolly Roger seem to single-handedly support the airbrush sign industry in Ocean City?Ī Gravitron with its "Gravitron" sign newly removed for 2009.įun Slide (named by the same person who comes up with the names of Cedar Fair rides, apparently). The Giant Wheel apparently is a great place to store boxes. and white guys demonstrating Indian stereotypes. (Most of the rest shared ride ops, usually one op per three or four rides, it seemed.)ĩ0 DEGREES! (Note the kiddie bumper boats at the left-this is integral in making sure you have seen every ride at Jolly Roger.) It was clearly the most popular attraction at the park and just about the only one with a full-time ride op. While that train is undergoing repair, let's take a look at this one. And unlike the rides, each and every single one of them was staffed. Jolly Roger also offered a full complement of games. Hey Big Mike, how many duckies are in here? Which brings to mind two questions: Why would a park want to theme anything (other than maybe a haunted house) as a decrepit building, and what is anything remotely having to do with theming doing at Jolly Roger? The backside of the stage is themed as a decrepit old house. You want to eat at Jolly Roger? This is where you go. I know a few readers out there who wouldn't mind trying Big Willie's banana. The park's property also contains a number of upcharge attractions, including two miniature golf courses. Jungle Golf is by far the most elaborate of the two. Treasure Golf, on the other hand, is nice too. Along with this quasi-elaborate entrance, they actually sprung for a handful of fiberglass statues to spread throughout this course. Jungle Golf is by far the better of the two. Splash Mountain is Jolly Roger's upcharge water park. You probably shouldn't expect to find Br'er Rabbit here. You'll find the upcharge go-kart concession at Speedworld. The fact that they took the effort to paint the tires astounds me. Note to Jolly Roger's marketing department: Threatening patrons is probably not the best way to get them to visit your second location at the Ocean City Pier. You get to see everything I saw-only you get to do it sitting down in the air conditioning! Enjoy! With that in mind, I now present to you every single ride at the park. I think I can legitimately say that if not for its adjacent water park, this permanent carnival would have become condos a long, long time ago. Now, I hadn't been to Jolly Roger since they took us there for a class trip when I was in third grade. Being the wonderful girlfriend she is, Kelly agreed to let me spend part of our day chronicling Jolly Roger Amusement Park. It's great living 30 minutes from the beach in the summertime! With a long weekend for Independence Day, my girlfriend Kelly and I decided to head to Ocean City, MD, on Friday for a little sun and randomness.

In addition, users can use the server to watch online content including live TV or RSS feeds. In MMW, click Tools > Options > Media Sharing, and verify that a server is enabled and running. If you are using Windows Firewall these will be open for you automatically by the installer. Make sure you open TCP 8895 and UDP 1900 ports in firewall. Mac users need to unpack the archive and run the installer. Linux users need to unpack the installation package to a desired location.

Please remember these good men this Memorial Day. I am sure that when I leave this world, my last thought will be of my family and my comrades. It was a part of the bargain we all made, the reason we were so willing to die for one another.Īs long as I have memory, I will think of them all every day. They would have carried my reputation, the memory of me. They were willing to guard something more precious than my life. But I know them in a way I know no other men. They were delivered by fate and the military. Comrades gather because they long to be with the men who once acted at their best men who suffered and sacrificed, who were stripped of their humanity. Not to tell stories or look at old pictures. "I now know why men who have been to war yearn to reunite. I miss being able to do that so please indulge me. For the last several years when we would end up at our house having come out of DC, I would read this poem. We would always reflect on and raise a toast for those that didn't make it home.

For more information on the performance of venture capital funds and all other types of private equity fund, please click here. This consists of 5 multiple calculations metrics and 4 internal rates of return calculations metrics. This fund and investment-level performance information is drawn from the quarterly and audited annual financial statements of the fund managers and each. Bottom quartile funds show similar trends, with their upper boundary in the 0-20 range for vintages 1990 to 1997, while since vintage 1998 they have remained negative. These returns, and the performance of the companies post-IPO, caused a rush of money into venture capital, increasing the number of venture capital funds raised. There are typically nine VC metrics used to determine fund's health and performance. Understand the difference between IRR and multiple calculations. The index replicates the performance of our Venture Capital Research Index through a combination of liquid, publicly listed assets. They all have their own strengths and weaknesses, so it's important to look at a variety of them when making investment decisions. The average VC fund generates a 19 internal rate of return (IRR), according to Cambridge Associates. VC performance at a high level is typically measured using three metrics: TVPI, DPI, and IRR. One of the most important things to keep in mind when looking at venture capital metrics is that no metric is perfect. Venture capitalists use these calculations to assess the performance of startups.Īdditionally, these metrics can help identify trends and red flags that may be indicative of problems down the road. VC metrics can also give insight into the overall health of the startup ecosystem. It is necessary to make calculations on companies that have high growth potential because of the risk factor. Most importantly, Venture capital metrics provide a way to compare different investment opportunities and make informed decisions about where to invest. One moment delay when checking one password turns into years of waiting when checking billions of passwords. This trick is called key stretching it is an easy way to make brute force search more time consuming by requiring repeated hashing. hundreds, thousands and even tens of thousands times. That is why the hashing algorithm does not immediately release the encryption key. (the guys behind protection algorithms in Adobe Acrobat 9 should know what it's all about :) When you enter a password, a special algorithm called hashing algorithm converts the password into an encryption key, and passes the key on to the data encryption algorithm. More often than not, the delay will go unnoticed (or it may leave a positive impression: "it is taking so much time - the security level must be really high!") when you enter one correct password, but it does slow down the speed of searching during a brute force attack. Remember I said that data security vendors use their own methods to deal with password hacking attacks? For example, they slow down the rate of password checking. Now that we have covered passwords settings and the range of trial passwords, it is time to crack the password. As you change input parameters, the program estimates in real time the number of generated passwords and approximate time to completion. Our programs give perfect visualization of these calculations when you configure a brute force attack. 3-character password – 26^3=17576, etc.Ĭracking a 1-character password of uppercase and lowercase Latin letters will require testing of 26*2=52^1=52 passwords, and in order to crack a 3-character password 52^3=140608 passwords will be generated and tested, etc. So, in order to guess a password of only 1 lowercase Latin letter 26^1=26 trial passwords will be generated. Number_of_passwords = charset_length^password_length As the password length is increased, the number of trial passwords will grow exponentially, for example: The longer the charset that may include the right password is, the more trial passwords there will be. How long you'll have to wait depends on two factors: the number of words to test and the speed of brute-force attack. Such a guessing technique is referred to as brute-force attack. Only in this case a program does it for you at a rate of tens-hundreds-thousands-millions-billions of passwords per second. It is as if you were actually entering all trial passwords one by one until you find the one that fits to open the file. To date when breaking secure passwords, one uses password guessing attacks. What's the Difference?ĭenis Gladysh, co-owner and head of Passcovery, a supplier of high-speed GPU-accelerated software solutions for recovering passwords of popular file formats We've also featured the best password recovery solutions. Each new password comes with a unique QR code so you can transfer it to a phone or tablet as required. Choices include alpha upper (A–Z), alpha lower (a–z), numbers (0-9), and symbols. In addition, you can specify what type of characters you want your password to include. During our testing, we were able to easily generate a random string up to a million characters long in a matter of seconds-not that you would ever need one of this length. In theory, you can create passwords that are as long as you want. On top of this, the Strong Password Generator allows you to specify the length and composition of your new login. All new passwords are created locally on your computer, which means they aren’t ever stored online or on the program’s servers. This simple yet secure online program is designed to create unbreakable passwords at the click of a button.

This provides an early warning in case of environment issues such as something that works on a laptop (eg: Mac or Windows) but fails or behaves differently in production (eg: Linux). It's a good idea to have the base image be the same as the projects' production environment. This particular project uses Ruby version 2.6.6 and is deployed on Debian Stretch. Start by creating a Dockerfile at the root of the project as follows. Run Rails with changes on host machine reflected in container In order to proceed with the next steps in this post, make sure Docker is installed, this installation also comes with docker-compose. Here is a visual representation of what we will be creating: For example, it would not make sense for the container that seeds the database to start running before the container that houses the MySQL database is available.ĭocker Compose is a great tool to coordinate and synchronize multiple containers for this purpose. However, these containers will need to communicate with each other, and be coordinated such that they run at the appropriate time. Looking at what's needed to run a Rails app (server, webpacker, MySQL, Redis, etc), it becomes clear that each of these is a separate concern, therefore should be run in a separate container. For instance, a web application stack might consist of three separate containers, each with its own unique image, to manage the web application, database, and an in-memory cache in a decoupled manner. Decoupling applications into multiple containers makes it easier to scale horizontally and reuse containers. Introducing docker-composeĮach container should have only one concern. For those unfamiliar or new to Docker, I recommend the Docker Deep Dive course on Pluralsight. A quick note first - this post assumes knowledge of Docker concepts such as Images, Containers and Volumes. This post will walk through the setup, to achieve each of the above workflows steps. Being able to access an interactive Rails console.Running one off commands such as applying database migrations or running tests.Debugging with either a command line debugger ( binding.pry) or an IDE such as VS Code.Running a background job processor (this project uses Active Job, but Sidekiq could be used instead).Running a Webpack dev server so that changes in client side code made on host machine are automatically compiled in container and browser is automatically refreshed to reflect these changes.Running one-time setup tasks such as applying the schema to database and populating it with db/seeds.rb.Running the Rails app with changes to server side code made on host machine automatically reflected in container.Development WorkflowĪlthough there are many benefits to using Docker for development, there are also some challenges such as how to run tests? how to debug? In order for the Docker setup to be effective, it needs to cover the entire development workflow, including: This was a hedge in case something was found that could not be made to work with Docker. all dependencies installed directly on laptop. It was also important to ensure the project could still be run the "old fashioned" way, i.e. The goal of packaging everything with Docker was to make it easier and faster for new developers to get up and running. The existing setup involved developers installing all dependencies on their laptops and took some non-trivial amount of time to get working. This app has a React front end built with Webpacker, client side dependencies managed with Yarn, runs background jobs with Active Job, and uses a MySQL database and Redis. At work, I was recently tasked with Dockerizing a Rails monolith. |
