  Dart is to JavaScript as C# is to C++

Given the background of Lars Bak, the Google engineer whose V8 JavaScript interpreter upended Firefox's claim on speed, it was reasonable to suspect Google's new Web development language might look a lot like Smalltalk. But that might have taken the Web in a strange and different direction. Today, on the day of a Web developers' conference in Denmark, Google and members of the Chromium open source development team raised the curtain on Dart, the company's bid for a new and somewhat more str...

  Web Design is 95% Typography

95% of the information on the web is written language. It is only logical to say that a web designer should get good training in the main discipline of shaping written information, in other words: Typography.Information design is typographyBack in 1969, Emil Ruder, a famous Swiss typographer, wrote on behalf of his contemporary print materials what we could easily say about our contemporary websites:Today we are inundated with such an immense flood of printed matter that the value of the individ...

  File upload in PHP

File is a special kind of form data, when being uploaded to the server through HTTP POST request, PHP will create a $_FILES global array, the relevant file information will be stored in this global array. We will illustrate file upload with some code snippets using PHP and look into the internal work mechanism. Lastly will talk about file upload security. File upload In order for users to upload files in client side, we have to provide a form on the user interface. Since the uploaded file is a s...

  It’s Not China; It’s Efficiency That Is Killing Our Jobs

The majority of wealth is now concentrated at the top of the social ladder. This is particularly true in the US, and the gap is widening every year. This, I believe, is because of efficiency, not China. Today the best ideas can efficiently and quickly propagate worldwide, and everyone can efficiently find them and buy them. This makes the owners of these ideas filthy rich, and those ideas that are not the best, can hardly survive. It’s not just transfer of information that is fast; wealth...

  Ruby is beautiful (but I’m moving to Python)

The Ruby language is beautiful. And I think it deserves to break free from the Web. I think the future of Ruby is firmly stuck in Web development, though, so I’m going to invest in a new language for data analysis, at least for now. This is a look at the fantastic language I came to from Java and a look at a possible candidate. (Update: I’ve since written a followup.)Java to RubySix years ago, I added Ruby to my technical arsenal. I learned C++ and Java in high school, and I p...

  Never create Ruby strings longer than 23 characters

Looking at things through a microscopesometimes leads to surprising discoveries Obviously this is an utterly preposterous statement: it’s hard to think of a more ridiculous and esoteric coding requirement. I can just imagine all sorts of amusing conversations with designers and business sponsors: “No… the size of this <input> field should be 23… 24 is just too long!” Or: “We need to explain to users that their subject lines should be les...

  20 Database Design Best Practices

Use well defined and consistent names for tables and columns (e.g. School, StudentCourse, CourseID ...).Use singular for table names (i.e. use StudentCourse instead of StudentCourses). Table represents a collection of entities, there is no need for plural names.Don’t use spaces for table names. Otherwise you will have to use ‘{‘, ‘[‘, ‘“’ etc. characters to define tables (i.e. for accesing table Student Course you'll write “Student Cour...
