Update/expansion of my intro last year. I'm now going into fourth year maths rather than theoretical physics, having switched degrees. (That's assuming I pass some exams this week that I deferred due to illness).

I brew beer as a hobby, and code when I have spare time. I enjoy writing science fiction, but I'm a long way away from publishing anything.

I have 111 characters spare so: My favourite equation is \(\int_M \mathrm{d}\omega = \int_{\partial M}\omega\)

I have access to a laser engraver this weekend.

Sucht ihr nach einem neuen Bastelprojekt? Wie wäre es mit dem TTL-Mikrocomputer @gigatronTTL, präsentiert von Marcel van Kervinck auf dem VCFB 2019? https://vcfb.de/2019/ausstellungen.html#gigatron Alles zum Gigatron findet ihr hier: https://gigatron.io/

Be sure to test this! jcs@ has done the seemingly impossible, in addition to further refining the pledges for Firefox, and adding new pledges for the GPU process, he's also done the heavy lifting to add unveil(2) support! Reducing the very broad {r,w,c}path filesystem access.

RT @jcs@twitter.com I've been working on enhancing the security of OpenBSD's Firefox port over the past couple weeks and would like some wider testing https://jcs.org/patches/ff-port-unveil6.diff

Google kind of sucks. I am curious about how close to the speed of light we can get (in a spaceship for instance). We're not even close to 0.01c as things stand, but I have many questions: are there engineering reasons to believe we will/won't get to p*c for any p? What tech is being proposed/ruled out etc. no matter what I search, google shows me things like "why can't we/what would happen if we go faster than light?" and all sorts of intro stuff that I already know.

Wow, we did not expect the level of interest you all have had in the #PineTime!

More info:

- Cost will be approximately 25USD

- Charging dock included in price

- Built-in heartbeat monitor

- Case built of Zinc alloy and plastic

- Battery life measured in days

- Sorry, can't run Linux itself. SoC is nRF52832, which uses a Cortex-M4 core. That's why we need FreeRTOS :)

Given \(M, N\), matrices, let

\[m_{ij} = \lfloor \log_2 M_{ij} \rfloor \]

and similarly for \(n\). Then \(M_{ij} \approx 2^{m_{ij}}\). Define \(m \star n\) by

\[(m \star n)_{ij} = \max_k (m_{ik} + n_{kj}), \]

This gives us an approximation \((M \cdot N)_{ij}\approx 2^{(m \star n)_{ij}}\)

Has anyone here encountered this before? It's essentially floating point matrix multiplication without the mantissa bits, but I'm wondering if there are any papers or resources dealing with it.
