Importance of Semantics
semantics | /sΙͺΛmΓ¦ntΙͺks/ | noun (functioning as sing)
β the branch of linguistics that deals with the study of meaning, changes in meaning, and the principles that govern the relationship between sentences or words and their meanings the study of the relationships between signs and symbols and what they represent (logic)
β the study of interpretations of a formal theory
β the study of the relationship between the structure of a theory and its subject matter (of a formal theory) the principles that determine the truth or falsehood of sentences within the theory, and the references of its terms
Application Models
A typical business application is composed of several flows or use-cases. Also, these flows consist of logical ones like a transaction that spans several flows. Take for instance an e-commerce application which consists of user registration/login, product lookup, and one of the most important interactions in an e-commerce application β the shopping cart, and much more. Although these application flows might appear to be discrete and independent of one another, it is after producing a working solution that we realize that these flows are inherently interrelated for one reason or another. The idea of designing stateless application flows is many times confused with the relation between the flows. More ...
Iterators vs. Generators
Yes, there is a difference. Although both produce the same end effect, an iterator is not the same as a generator. The difference is in the way it is implemented and also consumed. Iterator is a (design/implementation) pattern while Generator is a language construct supported by the compiler. More ...
Mundane vs JINQ Way
New things are not always instantly accepted. Beyond skepticism, new things challenge the comfort people are accustomed to. JINQ wasnβt particularly welcomed. It was either discarded as unknown angel or worse β¦ ridiculed. However, JINQ still promises expressive succinct code. More ...
Text Editors
I am not a *nix commands expert β¦ but a professional? So why not relish educating my brother a couple of nifty commands, especially β find and grep, which he was looking into at the time. You can find a few more here if you are interested.
So much for the command line, watch out for the overdose1. I find it funny when people, especially developers, copy files on the command line on a Mac (or Ubuntu for that matter); I mean files on the local machine. Specifically, they either copy the file (Cmd-C) via the Finder and paste it, or worse drag and drop, on the Terminal 2(/posts/text-editors-rundown/#fn-1559-2). Our next laugh is about editing local files in vim π3.
Selective Combinations
More ...You have a list of strings with which you have generate ordered selective combinations of strings starting with the first string in the list. Let us say the list of strings is
abc,defandghi. I have to generate ordered combinations of the above list restricted to the ones starting with abc.
JINQ
JINQ (Java INtegrated Query) is an ultra minimalistic library inspired from and mimicking the .NET LINQ. While LINQ is a language level construct, JINQ is composed of types - classes and methods, but to the same effect.
Partial Classes β Java ???
I am really sorry if I tricked you into believing that Java is offering partial class feature. Unfortunately, Java doesnβt. Maybe never will. But I am going to talk about a workaround also presenting the thought process. Hence the length of the post. More ...
Sporting a new look
I am very particular about composing the content of the posts (and pages) on this blog. By content, I mean whatever goes in the body of a post/page β text, image, HTML, etc. I like to keep the content extremely clean and avoid polluting with HTML like I had to on Blogspot. With such content, it is a terrible pain to migrate blogs or render posts flawless and consistent across browsers. Blogger is notorious for that aspect1. More ...
Publishing C++/CLI on LeanPub
I came across LeanPub 1 a few months back. I believe it was through hanselman2 β blog, video or something. I liked LeanPub instantly because of a couple of reasons.
- It supports writing in markdown3 and I love markdown.
- There is a large collection and variety of books including technical books and material, some of which are free too.
- In case you are not a professional writer, the publication process encourages you with the feeling as if you are one.
I hadnβt written/published any lengthy material in a long time except the C+/CLI Primer on CodeProject4. Why not publish same, I thought, and actually published5. I wasnβt even expecting any response from anyone since the material was on C++/CLI, a language that gave me the impression that I was the only one using it at the time I published on CodeProject. π I am really impressed that the material topped more than 50 downloads in about three months since it was published. Heck, a couple of them even paid despite the fact that the material is free. Not only am I humbled by this encouraging gesture but I am also convinced that C++/CLI is still being pursued and will continue to live β production, academic or as a pet language. Go grab your copy of the booklet β C++/CLI Primer. Itβs free!
