We needed a test framework that helped us suss out flaky tests and fix them. We needed to have parallelizable integration tests to ensure our test run-times didn't get out of control. We needed to make testing asynchronous behavior ubiquitous and straightforward. #Macos runonly avoid detection for five codeMoreover, the nature of the code being built - complex distributed systems - required a testing framework that could provide for the needs unique to unit-testing and integration-testing such a system. And our test-driven development culture put a premium on tests as first-class citizens: they needed to be easy to write, easy to read, and easy to maintain. Engineers jumping from one team to another needed to be able to hit the ground running we needed fewer testing bikesheds and more shared testing patterns. As a growing organization Pivotal would benefit from a shared testing framework to be used across its many teams writing Go. The need was twofold: organizational and technical. ![]() For engineers coming from the rich ecosystems of testing frameworks such as Jasmine, rspec, and Cedar there was a need for a comprehensive testing framework with a mature set of matchers in Go. At the time (and, arguably, to this day) the landscape of Go's testing infrastructure was somewhat anemic. A sprawling distributed system, originally written in Ruby, that was slowly migrating towards the emerging distributed systems language of choice: Go. Specifically, Pivotal was one of the lead contributors to Cloud Foundry. #Macos runonly avoid detection for five softwareThe first commit to Ginkgo was made by on August 19th, 2013 (to put that timeframe in perspective, it's roughly three months before Go 1.2 was released!) Ginkgo came together in the highly collaborative environment fostered by Pivotal, a software company and consultancy that advocated for outcome-oriented software development built by balanced teams that embrace test-driven development. Like all software projects, Ginkgo was written at a particular time and place to solve a particular set of problems. #Macos runonly avoid detection for five freeIf you just want to dive straight in, feel free to jump ahead! This section captures some of Ginkgo's history and motivation. These docs are written assuming you are familiar with Go and the Go toolchain and that you are using Ginkgo V2 (V1 is no longer supported - see here for the migration guide). We suggest starting here to build a mental model for how Ginkgo works and understand how the Ginkgo DSL can be used to solve real-world testing scenarios. The narrative docs you are reading here are supplemented by the godoc API-level docs. ![]() In reality, Ginkgo is a general purpose testing framework in active use across a wide variety of testing contexts: unit tests, integration tests, acceptance test, performance tests, etc. Ginkgo is sometimes described as a "Behavior Driven Development" (BDD) framework. When combined, Ginkgo and Gomega provide a rich and expressive DSL ( Domain-specific Language) for writing tests. It is best paired with the Gomega matcher library. Ginkgo is a testing framework for Go designed to help you write expressive tests. ![]()

The Invention of Spectacles: The modern reinvention of spectacles occurred around 1280-1285 in Florence, Italy. Strangely, even though this must have worked quite well, and many people must have read this passage, there is no other evidence of spectacle use for over twelve centuries. The Emperor Nero used to watch in an Emerald the gladatorial combats.” This quote appears to be the first description of using a monacle for correcting short-sighted vision. Pliny the Elder wrote the following in 23-79 A.D.: “Emeralds are usually concave so that they may concentrate the visual rays. There is one very early description of an isolated use of spectacles. However, studies of early Chinese spectacles show that often the lenses were planar, without corrective abilities, and people may have actually used these colored glasses for cosmetic purposes rather than for astigmatism. Early Evidence of Spectacle Use: It has been said that spectacles were in use in China well before they were known in the West. It wasn’t until the invention of spectacles that optics came into common use. While the above exerpts give a glimpse at optical knowledge in the past, it’s important to realize that this knowledge was likely confined to the learned scientists and philosophers. If the letters of a book, or any minute object, be viewed through a lesser segment of a sphere of glass or crystal, whose plane is laid upon them, they will appear far better and larger. 1267 AD Bacon Wrote definite descriptions of simple magnification in his Perspectiva of 1267: “Great things can be performed by refracted vision. ![]() ![]() He wrote the following: “Letters, however small and indistinct, are seen enlarged and more clearly through a globe of glass filled with water.” 962-1038 AD: Arabian Scholar Alhazen: Wrote the first major optical work Opticae Thesaurus discussing not only optical principles, but described the anatomy of the eye, and how the lens of the eye focuses an image on the retina. 1st Century AD: Seneca: Described actual magnification by a globe of water. He then very accurately calculated the refraction constant of water. 2nd Century BC: Claudius Ptolemy:Described a stick appearing to bend in a pool of water, and accurately recorded the angles to within ½ degree for this relationship. Ancient Writings of Optics Several ancient manuscripts give us datable evidence of the state of refraction and optics throughout the ages. It’s now thought that lenses were not used nearly so long ago. It is now generally agreed that this stone was actually just an ornament which fell away from it’s mounting. ![]() Secondly, cloudy striae within the stone, which add an aesthetic quality, make it a poor magnifier. In the last century, however, studies of this object have shown that the curved surface is actually faceted, and not rounded, as one would have done to make a lens. This was long thought to be the first example of a plano-convex lens. The Lanyard Lens: The above is the famous “Lanyard Lens” discovered at Nimrod by Lanyard, and datable to 721-705 BC. This chapter should give some insighs on how optical theory developed making microscopy possible. Early History of the Lens: The first use of a lens is a bit of a mystery, but it’s now believed that use of lenses is more modern than previously thought.

The Mountain Feist is a dog breed, very similar to Jack Russell Terrier originating from the southern portion of North America. The color their coat comes in a large variety and include red and white, blue and white, black and tan, red brindle, red, black, and spotted tricolors. They have a height range of 12-17 inches at the withers, with a short, dense and smooth coat. Most of their ancestory can be traced to terrier breeds but it is thought that they may also.

![]() While you may spend a lot of time doing this in German class with your teacher, this is a constructed environment. Learning German at a higher level means formulating your sentences and speaking like German native speakers. Listen to and watch German media to hear native speakers If you’re learning German to study Engineering, it might not make so much sense to learn tons of food-related vocabulary.Īsk yourself: what is my purpose for learning German and what related vocabulary and phrases do I need to know to feel comfortable speaking in German efficiently and effectively? Once you have this answer, this is what you should focus your practice on. For example, if you’re learning German to work in business, it probably doesn’t make sense to learn German philosophy vocabulary. Keep your practice relevant for youīecoming fluent in German doesn’t mean learning every vocabulary word there is to know (this is actually impossible anyway due to composite words). It’s this point that propels you forward in becoming fluent, because when you learn to format sentences in a German way, you also begin to think “like a native German”. When you know how basic grammar works, you can combine vocabulary and grammar to create your own sentences. Learn basic german grammar how to#While many popular language apps give great vocabulary, they often don’t teach you how to use this vocabulary in different contexts and how the grammar is formulated. I would personally stress this third point: learn to form your own sentences. If you’re looking to be fluent in German in 3 months, you’ll want to give the Lingoda Sprint a go, because you learn the ins and outs of German grammar, get to practice speaking with native speakers, and also learn to form your own sentences. ![]() How long does it take to be fluent in German? Well, in order to get to “fluency”, you need to spend a lot of time practicing, but this can be done in a short period of time if you’re dedicated enough. In my opinion, this “fluid conversation” is what makes a person “fluent”, so I’ve compiled a few helpful tips to get you there. The most important is that people can understand you, and that you can understand others well enough to have a fluid conversation. What I can also say is that grammar isn’t as important as you might think. And while it is definitely complex, there is a lot of fun to it, too (I particularly love making up composite words). ![]() During my time at German language school, we spent a lot of time going over German grammar. The tricky part for most, however, is German grammar. But the good news is that if you’re familiar with English (or are a native English speaker like me), there are a lot of English words and phrases that are the same in both languages, such as “information”, “finger” and “minute”. As someone who has learned German as an adult, I won’t lie to you and say that German is easy to learn without practice. ![]() |
