Re:An Intuition for Lisp Syntax on Friday May 28, 2021 @02:42AM (#27312410)
I mean it's literally the same idea as in set theory.

phi is an empty set,

(phi) is a set containing an empty set

((phi)) is a set containing a set containing an empty set

Furthermore, it's one of the only syntax rules; if it's not a list, then the first element is an operator/function.

Re:I want a computer that I own on Tuesday March 09, 2021 @12:50PM (#26401400)
My daily driver is a thinkpad X200 that I librebooted myself.

I kid you not when I say that I derive immense pleasure from using it. Apart from a few (equally freedom respecting) devices I find, I literally never feel like I'm wanting for anything.

I can't recommend it enough. I don't have the words.

A distant friend in college was completely blind; an exceptional student that you'd catch studying with his screenreader. I asked him about his experience of it; he was using a mac, and they apparently have some pretty good integrated features for that type of use. He was getting some help with having some material transcribed so he could read it. I wanted to try something like it, but proprietary software is was the table.

To that end, I used Emacspeak for a couple of weeks earlier last year, to extend the range of my interface with the computer. It didn't stick, but I'm about to give it another go soon. Audio cues are absolutely superior to visual ones in some contexts, and emacspeak is definitely amazing.

Humans have mastered so many instruments with esoteric interface designs constrained by physics (I'm imagining mostly musical ones, but I'm sure there's others), but HCI innovation since the keyboard and mouse has been basically 0. Visual interfaces (from text) were a gigantic leap forward, but made tasks trivial from the command line hard (can't pipe a visual interface), and tasks impossible from the command line easy (drawing a freehand line on screen). Touchscreens were a great invention, but their real advantage is their versatility. They suck along so many other important measures like accuracy, tactile feedback, speed of inputs, multiple inputs etc (try typing with your eyes closed on your actual keyboard vs cellphone), yet plague all devices no matter their purpose (touchscreens for important hardware inside a vehicle/heavy-machine? Fuck you.)

Interface design (for the masses) is stagnant/worse with every year. "Best to stick to an impotent interface that's understood, easy to control and monetize."

All of these, and the author's original problem with their prosthetic are a symptom of the plague of spectacle over substance.

Re:Ask HN: What are your favorite roguelike games? on Sunday November 22, 2020 @11:32AM (#25178717)
Cataclysm DDA is probably my favourite, but I don't like playing more than a single character at a time, and when I get too far into the endgame, I get bored with it, I usually just kill my character in some ludicrous/stupid way.

That's usually when I play Dungeon Crawl Stone Soup. I think the recent versions are all garbage (I guess there's some pitfalls to democratized game-development), I play strictly version 23.0.

Between these two games, all my of roguelike itches are scratched. I'd say CDDA is sort of like single-player only Dwarf Fortress, and DCSS is Rogue/Angband distilled.

FTL is an INCREDIBLE game, but I've given it up cause it's proprietary software.

I also played some Tales of Maj'Eyal, but imo it's too combat focused for what RP elements are in it.

I've beaten all of these games, and DCSS around 20 times.

I recommend them all thoroughly.

Honorable Mentions: 1) Shattered PD for mobile 2) Slay the Spire

I read this paper in 2017, I thought it might serve as an interesting starting point for discussion.

I'm young, and living in a place where being a software engineer pays only marginally better than other professions. I haven't managed to gather the land/capital that I think I need to cope with the changes I believe are coming.

For the last couple of days, I've been trying to get a static website up using hugo (emacs + ox-hugo), and I've been using tramp to ssh into the machine and do my work.

Tramp is literally magic. It just puts the right text into your buffer, where all the tools you use on your machine are just available by default. Even org exports and the like behave as expected, outputting the resultant file into the correct dir on the remote machine.

I've been using emacs as a <50IQ user for about a year now. I've yet to write a single line of Elisp (apart from use-package declarations). It's awesome!

Thank you though, I'll make sure to check r/thinkpads!

Ask HN: Fitting a Rockchip RK3399 into an X201?

I've been using a librebooted X200 for 3 years now. It's no overstatement to say that it delivers the most holistically amazing computing environment I've ever worked in.If I'm to buy a new laptop, it must remain "superficially" identical/comparable. I want better performance, but what's ciritcal is getting as much battery life and improved thermals as I can. Even the screen is not as much of...

Yo I didn't know about this feature, tyvm.

Ask HN: Want to Acquire Thinkpad T400s

Hello, I'm currently using a librebooted x200, and I want to upgrade to a t400s (for the screen, increased CPU cache, and touchpad). However I can't seem to find one anywhere. I was wondering if there's a cabal of thinkpad enthusiasts who could help me look somewhere better than ebay. I already own a t400, but it's honestly too bulky to fit properly in my backpack with the rest of my belongings.

Ask HN: Reference for preindustrial chemical syntheses and their uses?

Hey guys, I was playing Cataclysm:DDA, and I noticed it let you make ammonia from salt water, a little research showed that it is possible to do this with electrolysis and a high enough temperature.I've had a long standing dream of moving into the woods tm, and I was wondering if there's good reference material for what important chemicals existed in preindustrial society, and the ways that...

> You might be ascribing quite a bit more leverage to System76...

This may be true, but I think that selling corebooted computers is literally just a marketing gimmick. If a computer ('s motherboard) is corebootable, I can coreboot it myself, or lacking the technical skills, ebay have it done for ~$50 (maybe with video proof that the flashed rom is what is expected by showing hashes)

I don't expect ANYONE to be able to make intel or amd do anything about this situation, which is why I acknowledge your point:

> Now, offering something else (ARM, RISC-V, POWER, anything but x86) as a truly open source alternative...

I would love to see a POWER laptop, but I don't have the technical knowledge or money to help make this happen.

What I think is holding this back the most is that there are very few people with an ecosystem where they can compile all their own programs, meaning that 99% of computer users won't be able to make use of the general purpose computer underneath, because the software they NEED for their work absolutely will not run on it.

As a user however I think freedom is paramount, I'm about to finish up my CS undergrad, and about 3 years ago I became aware of the issues surrounding freedom in computing (literally never brought up in any of my classes), and I bought all the components needed and librebooted myself a thinkpad x200, which I've been faithfully using with parabola/debian ever since. Thankfully this as a platform was within my financial reach.

> With our baseline blob-free systems...

I laud the efforts of raptorpcs, but these systems are completely out of my reach. My previous sentence should show that I'm willing to compromise a lot to have freedom (no usb 3.0, I stopped playing games that have proprietary code, rebuilt my ecosystem so as to never have to move away from totally libre software etc)

I recognize how the fact that these machines exist means that a motivated company can choose to have a free system and that's great!

What I'm looking for as a normal user though is a LAPTOP that has these features, and that's why I get hype when someone claims to have one, but it's always a dissapointment, eg. purism.

I feel like I'm ranting, but it's honestly a little unclear what I'm responding to.

I just meant in terms of aligning with their profit motive; i guess the correct word is incentive, rather than responsibility. I see your point
I'm not able to update my post, so I'll leave my edit here:

EDIT:

If I wanted an ALMOST foss laptop, I would buy a laptop and coreboot it myself. The reason that it's exciting for a company to be doing something like this is because they have leverage in their decisions that I don't as a customer (custom cpu, custom components, choosing components with open firmware that already have good interoperability on the platform etc)

These computers runs blobs in the firmware and are not fully open source. I understand that modern users want modern performance, and that there is only a niche market for a librebooted computer (mostly due to performance), and as a company, it's systems76's responsibility to meet the market. But solutions exist, and if you are trying to market an open source computer, then give me an open source computer. What I hate most is how the top comment is from Jeremy Soller, but they are literally using this forum as a marketing platform, only responding to the queries that potray their initiative as good, and ignoring the literal highest comment directly under their post. This is so disingenuous, give me true libre laptop. (C-f tpearson-raptor on this post, they even offers a real solution from raptor to try and make this real). I'm grossed out.

Hey guys,I haven't logged in to facebook in about a year now, and it's been over 4 years since I used it in any meaningful capacity. I'm sure that facebook will maintain some kind of shadow profile of me, since it's aware of my existence, and will do so even after I quit the platform, but I figure that there are technical barriers to maintaining these shadow accounts (I imagine that they don't...
