I've been looking for a really engaging solid intro to number theory course on youtube, including rings, Abelian groups, etc for early teens. Does anyone have a recommendation here…

Or go for one of these gamified math tutorials. For instance: this one teaches geometric proofs without mentioning the formalism, just letting you "unlock" the tools from a few "ax…

This is similar to the solution we used in Vega Strike https://www.vega-strike.org/ detailed here https://graphics.stanford.edu/~danielh//classes/VegaStrikeBl...

This article mentions the woes of circular imports. I thought MyPy let you work around that by doing if False: around your imports eg a.py: import c if False: import b class X: def…

I think the newer version of this is https://github.com/bazelbuild/rules_rust which lets you either vendor the dependencies or pull them from your Cargo.toml directly every time. P…

Does anyone have experience with eBPF on aarch64? How well is it supported? On what kernel revisions was it phased in and well tested there?

I was just experimenting with eBPF and ran into a limitation: Is there a way to load the source IP into a register when working in userspace? When I SO_ATTACH_BPF to a SOCK_DGRAM i…

Hi! Just noticed this post :-) I started the game in the late 90’s and open sourced it in 2001 The previous versions were win Mac Linux but the current dev team has been focusing o…

Ya we briefly corresponded in a mailing list some time back... he liked the multiplayer version, but wasn't interested in opening the source code yet. Maybe one of these years he w…

Wow you played begin too! I added multiplayer through DOSbox-- it was interesting that the AI craft were just like player craft but had a different controller. It was possible to s…

the way you run it is... run a retail copy of WC.EXE with the branch of dosbox3d then do wcnet startserver on one machine and wcnet connect then both machines just run wing command…

the clock rate isn't quite enough--because more enemies do cause it to advance the program counter more... really you do want to measure how long the frame took and sleep the inter…

It was WC1 and I disassembled the code and added in a time-dependent limiter in dosbox. I also added multiplayer--it's not quite documented and ready for consumption, but if you're…

There's the family plan which offers up to 6 members an account for a great monthly price. https://help.dropbox.com/accounts-billing/plans-upgrades/dro... With Dropbox Family, each…

For long term storage of blocks, we compress at much higher compression levels like you mention. These densely compressed blocks are, in turn, served directly to customers when the…

We heavily investigated zstd and met with the brilliant inventor, Yann, who provided amazing insights into the design and rationale behind zstd and why it is so fast and such an am…

Great question! We developed and deployed Lepton to losslessly encode JPEG image files. Lepton continues to deliver substantial storage and cost savings every year. You can read mo…

Savory with a touch of sweetness, Broccoli Bread cooks up like cornbread but offers fiber and calcium. The original name was Brot-cat-li (since files could be concatenated and comp…

Dropbox uses a similar toolbox as https://chromium.googlesource.com/chromiumos/docs/+/master/s... And yes, much of the overhead stems from the RPC server that needs to be implement…

Hi folks, I'm Daniel from Dropbox, and I am happy to answer any questions about this tech.
