  Algorithm : Reverse singly linked list

Questions about singly linked list are the lovers of interviewers during interviews given the characteristic that singly linked list is one-directional list and it's difficult to get the previous node of one node without some buffering tricks.  In this post, we will demonstrate one of the most frequently asked question about singly linked list -- Reversing the singly list. Given the first node of a singly linked list, reverse the singly linked list. For example : A->B->C->D After ...

  Does CEO of a tech company need to know programming?

For tech startups, there are usually only a few people at their early stage. To complete all the coding work in a short period time, it often requires that every one of the team including the CEO knows something about programming so that they can help complete the tense work as soon as possible. But does the CEO of other tech companies also need to know programming? As the CEO of a company, it's not necessary that they have to know about programming. The main job of CEO is to coordinate all the ...

  Name resolution order in JavaScript

To understand what value a variable has in JavaScript, we need to understand some concepts such as scope and name resolution order. JavaScript has two scopes; one is program level and the other one is function level. Unlike in C,C++ or Java, JavaScript has no block level scope. So a variable defined in a if block will still be available outside. For example, the below example: var foo = 1; function bar() { if (true) { var foo = 10; } alert(foo); } bar(); The alert will display 10 since the ...

  Eight C++ programming mistakes the compiler won’t catch

C++ is a complex language, full of subtle traps for the unwary. There is an almost infinite number of ways to screw things up. Fortunately, modern compilers are pretty good at detecting a large number of these cases and notifying the programmer via compile errors or warnings. Ultimately, any error that is compiler-detectable becomes a non-issue if properly handled, as it will be caught and fixed before the program leaves development. At worst, a compiler-detectable error results in los...

  Tom Uglow from Google : 5 steps to innovation

Google has been known for its innovation In Google there is a "welfare": each employee can spare 20% of his/her time to do what he/she likes to do so that any idea has a chance to be turned into reality. Perhaps this freedom makes Google capable of introducing new products and new ideas continuously. Google China held a small discussion session in its office in Tsinghua Science Park recently, Google Creative Director Tom Uglow shared some experience and cases of Google in production and innovat...

  Investing in myself: Realizing my value as a programmer

Being a programmer, you have an invaluable skill that you need to learn to harness. Investors realize this already which is why they’ll spend stacks of cash to have you build them something that’ll someday be profitable. Large corporations realize the value in good developers and sometimes bend over backwards trying to retain their top talent. To be able to program well is a skill that people clearly value but why do programmers tend to place such little value on their own ta...

  The roots of Lisp

(I wrote this article to help myself understand exactly what McCarthy discovered. You don't need to know this stuff to program in Lisp, but it should be helpful to anyone who wants to understand the essence of Lisp-- both in the sense of its origins and its semantic core. The fact that it has such a core is one of Lisp's distinguishing features, and the reason why, unlike other languages, Lisp has dialects.)In 1960, John McCarthy published a remarkable paper in which he did for programming somet...

  GoLang to build smaller executable file

Normally the executable file built with go is a bit large, it is always desired that a smaller executable file should be generated though. In this post, a couple of ways to reduce the size of the executable will be introduced. The end effect is that the executable file size would be much less than the normal generated one. The file which is built normally has below size. Mode LastWriteTime Length Name ---- ------------- ------ ---- -a---- 12/14...
