I made a few minor tweaks to the open source MCP2210 library during the past few days, and had also updated the documentation. In my previous post, I illustrated how to manipulate the GPIO pins using this library and today…
After a couple of weeks’ coding and testing, I finally finished the initial version of the MCP2210 C++ library for Linux. This library utilizes functions from Signal 11‘s HID API (hidraw) to communicate over the USB HID interface.
I just bought a Brother MFC-7340 multifunction laser printer to replace my old Lexmark Optra E310 which I have had for about ten years. Lexmark Optra E310 has excellent Linux support and I have been using CUPS to make it…
Whenever I setup a new web server, I always like the idea of keeping the Apache logs roated on a daily basis. While the procedures for changing the log rotate frequency is pretty straight forward, I have seen a lot…
I have finally got around to upgrade my web server. The server I have been using was an old Pentium III about 10 years old. It had been serving my website quite well over the years till recently.
Karmic Koala was released into the wild last Thursday, so naturally I was going to upgrade my desktop installations at home. In this past I had been doing fresh installs whenever there was a new release, since there might be…
In a heterogeneous computing environment (e.g. Linux and Windows), it is necessary to use Samba to share files between the Linux systems and Windows systems. Due to the security enhancements in Windows XP SP2 and above however, the administrative share…
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.
I was trying to search for some code examples on how to do a recursive directory search under Linux using C++ the other day. But to my surprise, I could not find any place that offers a complete example. So…
Last month,I upgraded one of my PCs from Ubuntu 8.10 to Ubuntu 9.04 and everything went rather smoothly. Since my main PC is running Ubuntu 8.04 (LTS) and there is no option to upgrade to 9.04 directly without going through…
In the example I gave in “Interfacing IPP with Magick++“, I illustrated how to use Intel’s Integrated Performance Primitives (IPP) to perform edge detection. One issue with Canny edge detection algorithm is that we need to specify a high threshold…
I was traditionally a KDE user till KDE 4.0 came along. While many users are excited about many of the new features (e.g. Widgets) added in KDE 4, I am simply no big fan of fancy user interfaces. So I…
Without much fanfare, Ubuntu 9.04 (Jaunty Jackalope) was released into the wild earlier today. But Ubuntu followers are wasting no time, overloading many of the official downloading sites.
So far I have been mainly using KDevelop and Code::Blocks as my C++ development IDEs. Recently, I started using NetBeans IDE for C++ and I started to like it quite a bit.
I had set up my apt-get source to use latest SVN build of Code::Blocks. Everything has been running pretty smoothly until a couple of days ago when Code::Blocks was updated to SVN 5534.
