I'll add to this that each degree at each university has a pre-published entry score. If you achieve this score, you are automatically accepted. The score is based on the previous year's intake, so the universities must predict de

If you happen to hand code ARM assembly, it is extremely convenient for working on the go.

I actually drew inspiration from halide. I think it performs well because memory access / cache misses are more expensive than a few extra instructions, but it has its limits. For example, I'm not sure how you'd implement the

I coded up a 5x5 Gaussian blur using NEON instructions. I used the standard seperatable filter technique, one horizontal pass and then one vertical pass. Benchmarking effectively measured 2x the memory round trip time on the raspberry pi. M

I have mild tinnitus in one ear, from what I suspect was a friend screaming into my ear that she was going to the bathroom at a noisy club. I'm relatively lucky, my hearing is still better than most, but it does suck. I've decided

I'm going to hijack this thread to mention that I'm thinking of open sourcing a SLAM system I've been working on under BSD or MIT. Ive been working on this because I'm interested in underwater drones (uuvs), and hope to

How do GPU's "wear", or in other words degrade with use. I often see people stating they would not buy an ex-miner GPU because of it's hard life.

This doesn't prevent the industry from getting together to make their product more accessible. It didn't stop them from banding together to make it less accessible (RIAA/MPAA).

I have to say that since I've been paying for music, I've always had the one complaint: Why does the industry insist that each music portal have a fragmented, incomplete catalogue. In a world where everyone pays for music, I suppo

Until you need to differentiate a quaternion ... Also, you don't pay the sin/cos costs when converting to a rotation matrix. For angle axis R = I + (sin x) * S + (1 - cos(x)) * S^2 Where S is the 3x3 skew symmetric matrix.

It seems you are right. IEEE doesn't say anything, which I guess makes it implementation defined. However, in glibc, there are definitely code paths for looking up digits of pi.

In most cases a Chebyshev approximation will just work. There is advice out there which says to use Clenshaw's summation formula to sum the Chebyshev polynomials, however I've found that expanding out the polynomial coefficients t

I'm half way through writing a blog post on how transcendental functions are computed in glibc, and more importantly how to extend the methods to compute things like sin(x) / x (1 - cos(x)) / x^2 directly without inc

The maths department where I attended did this for first year material. They put together a ~100 ish page packet that we paid something nominal for, making all other textbooks optional.

I’ve been working to get orb_slam to run on the raspberry pi in real-time. One of the most interesting parts, to me, is the bag of words approach to feature matching. It’s shockingly reliable for such a simple method. It’s used for initiali

As I understand it the military wants to prevent the FAA from decommissioning radio NavAids and secondary radar. The FAA had counted on $100 billion from the decommissioning after the introduction of ADS-B. Jamming GPS signals forces aircra

I hate this. I always thought that if I had some ailment I would research everything about it and try fix it. I still do that with tinnitus, but when I do I'll hear it.

I once had a Java job which required me to use an IDE. What I noticed is that I became dependent on the auto-lookup features and didn't really learn the codebase until at least a year in. I use vim, and whenever I need definitions from

I feel it really depends on the type of project. In my case the code is rather niche and would only really be licensed by a small number of companies doing embedded robotics or AR. However, this type of stuff is also fun for hobbyists, so I
