Open Source Needs a New UI
As a freelance web developer, I’ve seen and used my fair share of open source web applications (and desktop software), and I’d like to point out something that I see all too often in open source projects: the user interface almost always lets the project down. Let me explain… The Problem I’ve used a considerable amount of open source software (web-based and desktop), and I feel that a large portion of them are let down by their UI. The functionality is brill...

How Many C Programs Are There?
If I choose a size S, can you tell me how many valid C programs exist that are no larger than that size? I’m actually interested in the answer — it’ll help me make a point in a paper I’m writing. Shockingly, the Internet (or at least, the part of it that I looked at based on a few searches) does not provide a good answer. Let’s start with a few premises: Since it would be exceedingly difficult to construct the exact answer, we’re looking for a respe...

Get associated file icon with only extension name using C++ on Windows
I have searched on Google for a few examples on how to get associated file icon with only file extension name using C++ on Windows. There are some useful information provided on MSDN which explains the use of SHGetFileInfo() function.It also gives an example code, but it doesn't say how to do it with only the extension name. Here I give an example code on how to achieve this after I gathered and summarized some useful information from Internet. I have tested the code on my PC, it w...

Roundup on Parallel Connections
A lot of blogging and follow-up discussion ensued with the announcement that IE8 supports six connections per host. The blogs I saw: IE8: The Performance Implications IE8 speeds things up IE8: 6 Connections Per Host IE 8 and Performance Testing IE8.s Connection Parallelism IE 8 Connection Parallelism Issues It’s likely that Firefox 3 will support 6 connections per server in an upcoming beta release, which means more discussion is expected. I wanted to pull all the facts into one place an...

How to optimize MySQL insert statement
For a big data system, one problem is the data access efficiency, one more problem is that the data insertion is very slow. We had a service system, the data loading process would take 4-5 hours. This time consuming operation is risky since if the program is interrupted during the loading process, it might be rerun, this will be troublesome. So it's necessary to improve the insertion efficiency for big data systems. Here we provide two optimization suggestions. 1. Combine multiple insert stateme...

When Should Open Source Be Written Into Law?
As a systems administrator, I tend to think about source code and computing platform in large numbers. Computers however are getting smaller and more powerful, and the reality of computers that we put in or on our body as a normal daily routine is coming closer, and for many is already here. When our safety, our liberty, and our sense of humanity are tied to programmable devices, should we not only hope, but expect that we should have the right to examine how these devices function? Last ...

Here Are The 10 Highest-Paying Jobs At Google
South African job listing site JobVine compiled the following chart of the top ten salaries at Google, compiled from Glassdoor.The top pay is for contract positions leading software development. It's not uncommon to see contractors earn more salary than full-time employees at big tech companies, because they're often not able to get stock options and perks.For jobs within the company, it looks like directors of product management are the highest paid, which is fitting with Google's new...

An Object is not a Hash
Following my article A String is not an Error, I want to bring attention to an issue that similarly applies to JavaScript in general, but has special relevance in the Node.JS environment. The problem boils down to the usage of {} as a data-structure where the keys are supplied by untrusted user input, and the mechanisms that are normally used to assert whether a key exists. Consider the example of a simple blog created with Express. We decide to store blog posts in memory in a {}, indexed ...

Flash Player sandboxing is coming to Firefox
Peleus here. In December of 2010, I wrote a blog post describing the first steps towards sandboxing Flash Player within Google Chrome. In the blog, I stated that the Flash Player team would explore bringing sandboxing technology to other browsers. We then spent 2011 buried deep within Adobe laying the groundwork for several new security innovations. Today, Adobe has launched a public beta of our new Flash Player sandbox (aka “Protected Modeâ€) for the Firefox browser....

The Problem with Random Numbers
Today, let's talk about how to generate true random numbers. This is an extremely difficult problem, but it involves some very interesting content. First of all, the random numbers provided by programming languages are pseudo-random numbers. The V8 engine’s official website has an article that particularly reminds everyone of this point. The built-in random numbers are not true random numbers but pseudo-random numbers. Math.random() returns a Number value with po...
