SolidusCode Blog

It has been a minute or two since I last posted content on this blog.  Well, I am going to remedy that by posting now to announce that this blog will now become the official blog.   Please stay tuned and check in regularly! Thank you, SolidusCode

So recently I have been working on inverse kinematics as part of my game development project. The motivation is mainly because I have found it very difficult to export animation from blender to my projects. Blender pose bones are in some very weird transformation spaces plus the xyz coordinate system adds ta new level of frustration. I have tried countless times to force blender to export the animation to local space of each joint using parent-child inverse matrix but it never seems to work. Well, enough with that nonsense. I have written an excellent IK solver system and post a tutorial of on my website. Take a look . Comments are greatly appreciated.

If you ever run into a problem on Ubuntu where by your system update, software center, or synaptic fail to run properly and you get the following bug report: E: Encountered a section with no Package: header E: Problem with MergeList /var/lib/apt/lists/mx.archive.ubuntu.com_ubuntu_dists_precise-updates_restricted_binary-i386_Packages E: The package lists or status file could not be parsed or opened. You can type the following terminal commands to fix the problem: sudo rm -r /var/lib/apt/lists/* sudo apt-get update The problem was caused by previous attempts to update but your internet network failing to retrieve needed files, which results in Ubuntu getting confused.

Okay so I have posted a number of Linux kernel programming videos over at my YouTube channe , however I find that I need a place to post a sample code and the make file to build a module. So here it is. The Makefile obj-m := solidusmodule.o KERNEL_DIR = /lib/modules/3.2.0-25-generic/build PWD := $(shell pwd) all: $(MAKE) -C $(KERNEL_DIR) SUBDIRS=$(PWD) modules clean: rm -rf *.o *.ko *.mod.* *.symvers *.order *~ #include #include #include // file_operations structure- which of course allows use to open/close,read/write to device #include //this is a char driver; makes cdev available #include //used to access semaphores; sychronizatoin behaviors #include //copy_to_user;copy_from_user //(1) Create a structure for our fake device struct fake_device { char data[100]; struct semaphore sem; } virtual_device; //(2) To later register our device we need a cdev object and some other variables struct cdev *mcdev; //m stands 'my' int major_number;...

Hello internet, i just recently posted a video  on how to interface an AVR microcontroller with and LCD Screen (HD44780). Please watch the video and do comment.
