Do you have any experience using POSIX async IO (aio_read, ...) or Linux kernel async IO (io_submit, ...)? I'm curious in how throughput performance and CPU usage compares with these to SPDK. My (relatively confident) guess is that per

I took this class as a junior and then later co-taught this class as a senior undergrad in 2015. The motivation behind the student taught class is that it allows for more classes to be taught than could happen otherwise. As a student: Like

I also think his upfront time estimates were off. He estimated Ruby to be ~15% more productive than C. I don't write Ruby, but I do write a lot of C and Python. I'd estimate that it takes 5x less time for me to write a program in

Write an IRC bot with sockets. The program needs to listen to multiple networks inputs (the connections to different IRC servers) as well as respond to user input (or at least signaling). This is a great playground to try out different mode

I'm unsure about the floating point performance differences, but 2 other reasons for potential differences are (1) number of floating point units and (2) different clock speeds.

Are you located in Chicago? If so, sounds like your project would fit in perfectly at ChiHackNight: http://chihacknight.org/ I'm guessing that you are already familiar with ChiHackNight, but if not I recommend checking

Nvidia's main advantage over AMD for deep learning is software, not the hardware itself. Nvidia's software advantage has lead to network effects where almost all GPU supporting deep learning libraries build on top of Nvidia. There

Seconded on the dpdk point. I've been working with kernel bypass networking in C but it seems to me that the asynchronous queue based APIs would be perfect for Golang or even Javascript. The only project I've seen so far to make k

I initially thought this as well, but reading the code showed me it's actually O(1) to add each item to the set. Each cell computes in parallel (new_data < cell_data) & (cell_state == OCCUPIED). If this is true, then the cell wi

You are only mentioning the tech industry in Silicon Valley, which I admit is pretty utopian. This description excludes everyone else in Silicon Valley. You can't talk about income inequality while only looking at those with high incom

The fact that we don't understand how neural nets work despite the excellent results makes an AI apocalypse more likely, not less. This means that if we ever create strong AI, we will likely not understand it initially. Note: I'm

If you can generalize on similar problems and be correct more often than random chance, then you have a useful model regardless of the data backing that model.

I think it's a mix of effects. Tesla is definitely pushing car engineering in some respects, but as far as I can tell the only thing new in this story is that the feature was added to the cars in a software update. Do you really think

Any estimate of how much the sensors as well as compute infrastructure cost in something like the Model S? $100, $1000, $10k, more? I'd love to learn more about the increasing "computerization" of cars. Do you know of any goo
