A palindromic prime (palprime) is a prime number that is also palindromic. So out of curiosity I wrote a simple program a few days ago that can find the palindromic numbers within a given range. Here is the code in…
Many of you may still remember the capacitor plague that caused massive motherboard failures back in the early 2000s. While the practice of using cheap and unreliable electrolytic capacitors in computer components has largely died down nowadays, it seems that…
Prime number theorem dictates the asymptotic behavior of prime number distributions. In layman terms, the distance between prime numbers increases at a logarithmic pace. This gives the familiar logarithm figure.
About two years ago, I blogged about why hybrids were not saving us any energy by taking into consideration the amount of energy needed to produce the vast battery packs and the inherent low efficiencies in battery technologies.
I was writing an ASP.Net 2.0 web application using Windows authentication (since I needed to capture users’ credentials). The web application saves data into a MS SQL 2005 database using a SQL server account. While developing this application, I ran…
I am running Ubuntu 9.04 64bit. One thing I noticed is that the integrated debugger is behaving quite flaky for the included Monodevelop 2.0 package. After some research, it turned out that a lot of people are having similar issues.
It appeared that Google Finance was down for at least half an hour (from before 9:30 EST till after 10:00 EST) today. I captured this screen-shot during the outage:
In my previous three articles (1,2,3) I discussed how to use Canny edge detection and Hough transform to identify blur images. Here I will show some results from the algorithm discussed before.
I will continue where I left off in my previous post. After performing Hough transform, and extracted the longest sections of lines for each corresponding Hough line detected, we will need to calculate the gradients of the image pixels luminance…
In my previous post, I briefly discussed the rationale behind automated blur detection in digital imagery and did an overview of an algorithm that could be used to detect blur images. Here I will show some implementation details along with…
It is often necessary to identify and classify images based on their clarities. For instance, it is desirable for an automated process to locate blurred images within a large digitized image library and then automatically sharpen the blurred images via…
Getting LaTex style math equations to work in WordPress is actually pretty easy. I followed the advice here and everything seemed to work pretty well.
So Microsoft’s new search engine Bing has been available for the general public for a few days. While I have read about Bing here and there, I decided to do some comparison myself between Bing and Google.
Measuring the execution time for code sections can be done in multiple ways in C++. Except for the time resolution issue, different timing methods worked relatively the same in single processor environment. As multi-core processors become more prevalent however, we…
As I wrote last time, I did a clean Ubuntu 9.04 install on my main PC.
