A collection of variations on the joke that there are only two hard problems in computer science: cache invalidation and naming things. See the original quote by Phil Karlton and other riffs by Leon Bambrick, Mathias Verraes, Phillip Scott Bowden and Nat Pryce.

Several references to the quote "There are only two hard things in Computer Science: cache invalidation and naming things" can be found, such as Martin Fowler's blog and others. I'm .This article is a list of notable unsolved problems in computer science. A problem in computer science is considered unsolved when no solution is known, or when experts in the field disagree about proposed solutions. There are only two hard problems in computer science: Cache invalidation; Naming things; Asynchronous callbacks; Off-by-one errors; Scope creep; Bounds checking It's hard to overstate the stakes surrounding the most important unsolved problem in computer science. P versus NP concerns the apparent asymmetry between finding . There are only two hard things in Computer Science: cache invalidation and naming things. It’s been fun following this quote on the Internet for the past two decades. It’s .two hard problems in computer science There are two hard things in computer science: cache invalidation, naming things, and off-by-one errors.— Jeff Atwood (@codinghorror) August 31, 2014. My ideas on . There’s a saying that the two hardest problems in computer science are caching, naming things, and off-by-one errors. I think there’s just one hard problem: asynchronously . There are two hard things in computer science: cache invalidation, naming things, and off-by-one errors. — Jeff Atwood (@codinghorror) August 31, 2014. However, I .two hard problems in computer science Two Hard Things There are only two hard problems in computer science: 0) Cache invalidation. 1) Naming things. 5) Asynchronous callbacks. 2) Off-by-one errors. 3) Scope creep. 6) Bounds ."There are only two hard problems in Computer Science: cache invalidation and naming things." Phil Karlton. Is there a general solution or method to invalidating a cache; to know when an entry is stale, so you are guaranteed to always get fresh data? For example, consider a function getData() that gets data from a file. It caches it based on .Two Hard Things As the joke goes, “ there are 2 hard problems in computer science: cache invalidation, naming things, and off-by-one errors.” In this article, we’ll skip over why computer science only has one joke and instead focus on what makes cache invalidation “ hard” and demonstrate how it can be solved in the context of a content management system. In the subfield of theoretical computer science called complexity theory, researchers try to pin down how easily computers can solve various types of problems. P represents the class of problems . To explain , , and others, let’s use the same mindset that we use to classify problems in real life. While we could use a wide range of terms to classify problems, in most cases we use an “Easy-to-Hard” scale. Now, in theoretical computer science, the classification and complexity of common problem definitions have two major sets; which is “Polynomial” .

"There are only two hard things in Computer Science: cache invalidation and naming things" - Phil Karlton 计算科学中最难的两件事是命名和 缓存 失效。 在 DDD 实践中，这两个问题都会同时碰到，命名反映了领域模型的提炼过程，聚合边界的划分，说白了反映程序员的分 .

There are only two hard problems in computer science: 0) Cache invalidation 1) Naming things 5) Asynchronous callbacks 2) Off-by-one errors 3) Scope creep 6) Bounds checking If I have learned anything in my programming career, it is this: building reusable software, truly reusable software, is an incredibly hard problem – right up there with naming things and cache invalidation. There are two hard things in computer science: cache invalidation, naming things, and off-by-one errors.— They say there are two hard problems in computer science: cache invalidation, naming, and off-by-one errors. In this talk, we'll consider these problems in the context of diversity and inclusion in the CS/tech space, where they seem to get even harder:

The notion that some computational problems in math and computer science can be hard should come as no surprise. There is, in fact, an entire class of problems deemed impossible to solve algorithmically. Just below this class lie slightly “easier” problems that are less well-understood — and may be impossible, too.

There are only two hard things in Computer Science: cache invalidation and naming things. -- Phil Karlton, .In some ways, what computer scientists view as an easy or hard problem is very simple to determine. Generally, if a problem can be solved in polynomial time—that is, O . Another interesting and well-studied problem in computer science is the Traveling Salesman Problem or TSP. This problem tries to solve the practical task of minimizing the . "There are 2 hard problems in computer science: cache invalidation, naming things, and off-by-1 errors." "There are only two hard problems in distributed systems: 2. Exactly-once delivery 1. Guaranteed order of messages 2. Exactly-once delivery" 32 likes Like Reply Saurabh Sharma.

Perhaps the joke’s on us, and naming isn’t actually that hard, after all. Naming is just one part of the micro-design activity that we call programming. If design weren’t hard, we wouldn’t find good design so satisfying. For many problems the solution is clear: like designing a 10x cheaper Kafka or storing the whole Internet on a device. But if you want to invent the next generation of IDEs, it’s not. You have to.

Two: Three: Four: Five: Six: Seven: Same as with text alignment, there’s an endless supply of poorly aligned icons. Skill issue. Not only programmers fail to center things. Designers do it, too: Current version / my fix. The problem with icons is that sometimes you have to take their shape into account for things to look good: Bad centering . There are only two hard things in Computer Science: cache invalidation and naming things. -- Phil Karlton. In yesterday’s post I address the later; naming things.There are two hard things in computer science: cache invalidation, naming things, and off-by-one errors. Phil Karlton. . Getting the right representation for pixels coordinates and rectangles is an interesting problem. We used half open ranges for PixelBender to describe areas. It then makes sense to make the coordinates of the centre of the .
