I had the pleasure of installing Ubuntu on a modern Dell XPS recently. I was happy to discover that everything seems to work flawlessly upon install without any additional fiddling: WiFi, trackpad, touchscreen, display scaling, and really e

And if you know anyone who has paid for content that suddenly they had lost access to because of shut down DRM servers or intermittent internet connectivity, then you might be inclined to think a bit differently. Ultimately I think there ne

I agree. They're really great if you need well-priced, no-hassle infrastructure. As others have already mentioned, they may not have some of the higher-level features that AWS comes with, but if you don't need these, then there&#x

I really don't think their point was that it's not necessary for books and other physical media to be transferable to kids. I saw it more as an anecdote that I think probably a lot of people would, unfortunately, nod in agreement

I also run a project with Apache+PHP on Debian, with SQLite and a standalone C program that it interacts with running on the same machine. The whole setup runs on a single, low-spec VPS, and it too easily withstood the HN front page a few m

There's a good book, "Show Stopper!: The Breakneck Race to Create Windows NT and the Next Generation at Microsoft", which documents the original development of Windows NT in the late 80's and early 90's. A large amo

I really do think the hardware/software analogy here works quite well. In that sense, one could argue that the software has also become more complex, and perhaps more fragile, in recent times in order to better assist individuals in na

The way in which I like to often think about these things in practice is with "hidden" constant factors. For example, you can think of the O(1) algorithm as really taking O(1 * K1) time, and the O(n) algorithm taking O(n * K2) tim

It's certainly possible, but remember that with 8 bits you have just 256 different possible representations, and every instruction opcode with its set of all distinct valid parameters will map to a number of those limited 256 states. F

This is neat! I had some thoughts recently about creating something similar as well. For a simple but still practical instruction set, you can probably sanely get away with about two dozen or so different instructions, but at the expense of

I haven't heard of the Microtransat Challenge before, but this looks interesting, so thanks for sharing that! As for sails-simulator (first time looking at this as well), there appears to be, not surprisingly, quite a bit of similarity

Hey, thanks! Yes, different boat profiles is on my list of things to add at some point. There are some impressive global races [1][2] that happen every few years using some interesting boats, so it would be neat to follow along virtually in

Thank you for the feedback! There's definitely a tradeoff to work with when it comes to keeping things technical and finding a broader audience. I suppose there's also room for a "simple" mode vs. "expert" mode

Great tips overall, but if I may add a few additional points about this simulation... - The captcha can show notches in either 30 or 45 degree increments. I thought that the extra challenge of discerning between the two would be interesting

Hey, thanks! The boat's historical track is shown after some time (within an hour of starting), but it will only draw the lines between the positions at the top of each hour (so intra-hour positions are lost, but this isn't that i

The asymmetry between download and upload speeds on cable connections is really awful in recent years. I see advertised download speeds like 300 Mbps and 1 Gbps available in many places, but the upload speeds seem to never exceed 30 Mbps ar
