Labeling datasets is costly process. When you dont opt out, you're letting them build a labelled dataset on you-specifically for free.

Same for me: just say no, and they say OK. Effortless but the option is totally invisible.

The irony is, I've seen the staff stop using the face scanner for everyone halfway through the line to speed things up. So its not saving time, just costing money to increase surveillance.

Ignore the name (neural networks might as well be a footnote). A more appropriate title would be "generic problems and algorithms".

I agree, and here's a few different avenues of examples:

  1. If trying to get past interviews, Leet code and hacker rank can be great. They're not so great for real world problems, but not bad.

  2. Advent of code is a good middle ground between theory and practice in my opinion.

  3. To really learn real world problem solving, I'd recommend implement a specification, without looking at existing implementations. For example, make a basic regex engine (formal Regular Expressions not PCRE expressions), or try to implement the C Preprocessor, or the JS event loop.

"Algorithms to live by" https://www.amazon.com/Algorithms-Live-Computer-Science-Decisions/dp/1627790365

Less technical than you probably want, but it is useful for mapping real world problems to known algorithms.

Yeah, cookies, account logins, and other stuff make it hard too. Ex: randomly exploring gmail emails at different times of day, but not actually marking emails as read.

Psychology. Ever see ring doorbell footage where the owner says "drop the package" and people do? Its not like the owner could do anything, but for some reason it makes people behave differently.

Here's a very similar question I asked here a few months ago: "Privacy respecting ring doorbell" https://lemm.ee/post/8165932

If a human posted every 5 min, got 0 upvotes for 20 posts straight, we would ban them for spam. If bots would limit themselves to posting once a day, or once a week, and only post the top-voted non-duplicate post of that timeframe, it would be a dramatic improvement. For once, we might actually see real-lemmy posts along side bot posts, instead of the community being exclusively bots (or 99% bot posts) or exclusively Lemmy users.

I would tell the bot creators myself, except I don't know how to get in contact with them. Is there a consistent way to contact a bot creator?

I plan to speak to my city council about creating a tool library, where citizens use their existing library card to checkout tools. To make the idea a bit more robust, I'm also planning to require citizens deposit something as collateral when checking out a tool.

However.

I live in Texas (I love Texas). Thankfully my city council is receptive, but I know they're going to need compelling evidence before approving something like this.

So, if you guys have any advice, or examples, particularly of this kind of system working in the US, I would love to hear about it!

Cyberpunk themed rooms are pretty common, but I don't want to limit solarpunk discussion to just rooms; It could be as big as getting your city council to add a greenway, or as small as finding a nice desktop wallpaper. I'd like to hear about it. I'll start off with a few of my own:

  • I got a sunlight alarm clock; best decision I've ever made. The minimal design of this one is great except for one thing; you have you take 5 min to drill a hole in the dead-center of the speaker to kill the alarm noise. It's the only way to disable the sound. I'm sure there's other good options as well.
  • A couple years ago I got an EcoFlow battery with a small 100W solar panel. I mention it specifically because, unlike other batteries, the EcoFlow was extremely repairable, while also having top of the line specs (at least a couple years ago). I still haven't hooked up the solar panel to the grid, maybe next year.
  • I know plants help a ton, but you're going to have to get plant tips from someone else. Maybe someone will have some fake plant recommendations for me.
  • String lights and LED strips work wonders, both indoors and outside. Higher quality string lights (the lights are close together, bulbs are usually brighter and classic-looking) are quite a bit better than the cheap amazon ones, but even the amazon ones add atmosphere. Combine them with cheap timer-sockets and outdoor light sensor sockets to make a nice automated system.
  • I know it's kind of weird to consider going somewhere as part of a "theme" but I haven't found a farmers market that wasn't nice community. Last week I got an IRL side quest; one of the vendors heard I was going to visit the other market location and asked if I could bring a jug of sweetener to his counterpart there. Sometimes the people are them most important part of a theme, so I recommend participating in a market.
  • For transportation, there are some truly great e-options as of late. It's $300 for a cheap-but-good electric scooter on Amazon. I've also got an overpowered e-bike (Onyx RCR) and even at $4000 it's cheaper than a couple years of a car insurance and gas. Silently zooming with the confidence of being able to charge it off a solar panel is a really pleasant feeling.
  • Finally I've recently attended my first city hall meetings, and it's been shocking how helpful the city staff is. Absolutely nothing like the DMV or national politics. For example, I was told about a "SeeClickFix" app, and it has been great for getting street lights fixed.

It's not much, but that's all my tips.

Got any string lights of your own to show off? or maybe some watering systems, or plant tips? I wish we had an r/battlestations equivalent

 

TLDR; do you know of any general purpose languages that can also compile a function to some representation of AND/OR gates (or NAND gates, or whatever)?

Edit: actually any algebra/formal-logical system is also fine (not just boolean algebra).

Yes, a A LOT of additional info is needed, like defining how input/output is defined, and I am interested in how those would be specified. I'm not interested in printing an actual circuit, just the boolean-logic level. And I'm mostly asking because I feel like most compilers can't generate a clean/mathematical representation from their AST. There's AST to IR, there's hard-coded optimizations on the IR, and then there's hard-coded mappings from the IR to assembly, but at no point (AFAIK) is the code turned into a algebraic/logical system where something like De Morgan's Law can be applied. And that seems really sad to me.

So you could say my real question is: what compilers have a strong logical/algebraic internal representation of their own AST?

Maybe something like Haskell or Prolog do this. The Wolfram Language almost certainly does but it's closed source.

I know, this isn't a keyboard post, but lets be real, if there's any communities that would know/care about programable foot pedals it would be this one.

I'm looking for a USB foot pedal, ideally something clicky-feeling, with decent-resistance, short travel distance. I only need 1 pedal but something with more than one is fine. I don't need anything premium; I'm just browsing amazon I can't really spot the difference between mushy garabage and decent-ish build quality.

Any recommendations?

(Non-USB recommendations are fine; hopefully this post will be useful to others considering a foot pedal)

 

Its not much, as its a variation on Iosevka, exclusively for programming, and I made it a while ago, but I wanted to see what the community thinks. (I tried including a picture with the post but it failed to upload for some reason)

I'd love to see more open source self-made fonts. Any criticisims on functionality, or recommended changes are welcome.

 

I couldn't find a post in this community about cameras so I figured I'd make one. Requirements:

  • No "sign up" required to record video
  • Video is stored locally
  • Video is in a non-propriatary format
  • Can work offline

Optional/Discussion Points:

  • Can wireless connectivity be hardware disabled
  • Can auto-update be disabled
  • Does the device try to "phone home" if it is connected to wifi
  • Disk encryption would be nice but I doubt that'll be an option for anything other than self-hosted stuff

Does anyone know about Lorex (it seems more privacy centered)?

I'm highly technical, so feel free to mention self hosted raspberry pi soltuions as well.

 

I love a lot of the keyboards on here (especially ones with an integrated track ball) but I'm a poor grad student under deadlines; even most kit-boards are too much of a time sink for me to soldier together.

I know at least some of you like trying new boards all the time. And I'm guessing some of you have one or two daily drivers and then 3 older boards; maybe one that was a prototype build, or a novelty micro-board that was fun to just play with but not use, etc.

I would be happy to effectively fund a new kit/build for someone by buying one of those older (assembled) boards, but I don't know where to look.

Is there any kind of used market, or do you guys have any recommendations?

 

I would love if someone would write a parody of modern society. Something roughly like this narrative

Setting/Context:

  • energy becomes a non-issue (fusion powered cars; extra loud systems)
  • cars and highways get so big that people literally start driving their house to work
  • ads about "wait in line at the drive through from the comfort of your own home"
  • started with rich people getting drivable houses (not RV's or motorhomes; but driveable homes that are branded in a completely different way)
  • normal daily commutes of 100miles since everything is so padded out with parking
  • instead of owning land, some people just park in "overnight" areas with random neighbors (nobody knows their neighbors)
  • speeds are being increased because of the 100 mile daily commute, but it's causing increased accidents (nuclear) which are downplayed; people start padding their portable houses with radiation protection
  • Being too poor to afford a high speed portable home means you're effectively barred from registering to vote or perform daily tasks

Then:

  • someone (protag) has an idea of just staying parked permanently at his job's parking lot (he works at a grocery store)
  • His parking space is 1 mile from the front door of the grocery store so he "invents" the idea of mini-transportation
  • He convinces a handful of people to stay parked next to him and stars relying on them for small services (doctor advice, plumbing work, etc)

But:

  • the company won't allow any goods or services to be exchanged on their parking lot; those doctor services are illegal
  • cooperations band together to mandate no-overnight parkin (or some other better antagonistic thing, this is where my lack of writing skills is apparent)

Eventually:

  • (fight-club style expansion) there is a small movement of people planting their houses forming small communities on top of the massive parking lots
  • they repurpose their fusion generators
  • etc
 

if you ever browse r/gradstudents its about as depressing as posts on this sub; and if society's most promising students are constantly forgetting they're enough, maybe you did too.
