  Top 8 website operation laws

As a website operator, in addition to have some necessary professional knowledge to master a website, such as prototype planning, interaction design, SEO, as well as basic html code, you should also know more about some of the theories which are good for site operations to ensure that the site can be long-term, stable. 1.

  Go vs C benchmark. Could Go be faster than C?

During last semester I was attending Multiprocessor Architectures course, given at Facultad de Informática where I study my Computer Science degree. As part of the assignments due to pass the course, we had to do several programs written in C to benchmark matrix multiplication by testing different techniques and technologies. First of all we had to do a secuential program in three different versions: A normal one where the result matrix is ordered by rows and the loops range the matrix by ...

  Python Performance Tips, Part 1

To read the Zen of Python, type import this in your Python interpreter. A sharp reader new to Python will notice the word “interpreter”, and realize that Python is another scripting language. “It must be slow!” No question about it: Python program does not run as fast or efficiently as compiled languages. Even Python advocates will tell you performance is the area that Python is not good for. However, YouTube has proven Python is capable of serving 40 million videos...

  HTML5 and Accessibility

Accessibility for people with disabilities is a legal responsibility in many countries. It's also the right thing to do, and one of the characteristics distinguishing professional developers from the WWWs: WYSIWYG-wielding wannabes. But for many, accessibility has been a somewhat black art, requiring adding extra stuff to your code like alt text, table summaries, ARIA information that can be difficult to test by developers who are not assistive technology users themselves.The arrival of HTML5 ha...

  It takes hard work. Do the hard work.

Something I’ve been thinking about a lot recently is the idea of simply trying harder with everything I choose to spend my time on. It seems like an elusive thing, the idea of optimal focus and maximum effort. However, I think there is something to be gained from stopping for a moment and considering how focused we are when we do our daily activities. I think two things apply here: single-mindedness and massive effort. To truly excel at something, we need to be very focused. We can...

  Embrace open source

In past few days, there are many tech news which are related to open source. For example, Microsoft enables Linux on its Windows Azure cloud, Facebook open sourced its C++ library Folly and Samsung joined Linux foundation. Now more and more big companies realize the power of open source and are willing to contribute to the open source community. It will benefit not only developers but also these big companies as well.By providing some open source libraries or projects, developer may reduce their...

  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...

  We’re working our young people too hard

Yesterday, I shared an anecdote involving a school I once attended with a list. This anecdote eventually became the basis for a blog post. Traffic was fairly normal for the first few hours until it found its way onto hackernews.Then it exploded.The comments on both the original blog post and the post on hackernews filled almost immediately with opinionated hackers, teachers and students sharing similar experiences, discussing the problem and figuring out what should be done about it.Repeate...

  Prototypes and Inheritance in JavaScript

Forget everything you know about object-oriented programming. Instead, I want you to think about race cars. Yes – race cars. Recently I was watching the 24 Hours of Le Mans –a popular racing event in France. The fastest cars in the race are the Le Mans Prototypes. Although these cars are built by car manufacturers like Audi and Peugeot, they are not cars you’ll see on the streets and highways of your home town. They are built exclusively for high-speed endurance ra...

  New Linux kernel fixes power-saving issues

Greg Kroah-Hartman has released long-term kernel 3.0.20 and stable kernel 3.2.5. Both contain just a single bug fix that allows PCIe power-saving technology ASPM (Active State Power Management) to be used on systems with a BIOS that activates ASPM on some components, but states in the FADT (Fixed ACPI Description Table) consulted by Linux that ASPM is not supported. According to Matthew Garrett, who developed the patch, the change can reduce the power consumption of a Thinkpad X220 by 5&nbs...
