howrar, in Do you prefer PC or laptop?

If I had to choose only one, it would be a desktop. The experience of using a machine with a good keyboard/mouse and large monitors can’t be beat, plus it’s much cheaper for the same quality of hardware. The main downside is that it’s not portable. Whether I’m working or gaming, I’m confined to that one desk. I can’t work on the couch, in the park, in the waiting room at the doctor’s office, or anywhere else I might find myself that day.

The ideal setup is to have both. A desktop for when I can be at my desk, and a cheap laptop that I can use to remote into said desktop. That way, you get the convenience of a laptop with the power of a desktop at a much more reasonable price.

jayknight,

A monitor and keyboard/mouse that you can attach to your laptop gives you the best of both worlds.

But a desktop/workstation that you can leave on and double as a server for some things is nice to have.

darkan15,

I use my old laptop as a server, and so far no issues with leaving it on 24/7

pinwurm, in Getting Over a Breakup
@pinwurm@lemmy.world avatar

When a relationship ends, you’re watching something die. You will have to grieve, like you do for any death. Not just grieving for the end of the relationship, but grieving for all the lost opportunities.  The trips you haven’t taken together, things you haven’t said to each other, the family you never make together.

Unfortunately, it sucks.

These things take time to process, understand, learn from, and eventually move forward with.

You need to adjust to a new normal. And that new normal should be busy. Schedule regular gym visits, classes, language learning, book club, cooking, guitar time, whatever. Productive routine is important and it will help stabilize you.

Sometimes, the pain you feel will be greater than you built in resources for dealing with pain. This is when you add professional counseling to healing regiment. Please sing feel too proud for therapy. Even online therapy companies like BetterHelp are a great resource.

Go out of your comfort zone and say yes to being with people. Invited for after-work drinks, or a birthday party you don’t really care about… go anyways. You don’t have to talk to them about the breakup, just being around others will help you feel less alone.

Also, do a little house cleaning. Rearrange some furniture, get some new clothes, change the rug - something so what you see marks a clear before and a clear after. Take a vacation if you have some PTO and resources. You don’t have to spend any money or go anywhere. Just go to a park and chill on a bench. Relax a few minutes a day.

At a certain point, will be looking forward to tomorrows more than you look back at yesterdays. It could be weeks, months, but it’ll be a sign you’re ready to date.

BaumGeist, in Do you prefer PC or laptop?

I can’t use a laptop for work (graphics intensive, need a powerhouse) but I would if I could. I love being able to use it literally anywhere I go—at my desk, in bed, on the toilet, on vacation, on the bus, at a cafe, etc—and…

I installed a headless Debian OS, added a keyboard-focused window manager and I don’t have to futz with the trackpad nor find a place to put an attached mouse. It also is a much slower drain on the battery. Best of all worlds.

I use it for web-browsing, word-processing/spreadsheets, checking email, making memes, coding, managing my home network, controlling my headless SBC, and modding. Also occasionally for cyber CTFs or remoting into my desktop at least to do so.

doom_and_gloom, in Getting Over a Breakup
@doom_and_gloom@lemmy.ml avatar

You will have a void, and you will need to fill it (with something positive or exciting or fulfilling) or it will turn into rumination. You have questions, and some of them will always remain unanswered - you won’t find comfort in an answer that isn’t coming, but you can always find comfort by letting go of the question. You will be at a loss as to who to be and what to do, but you will find it again once you start living again. You won’t know how to move on, until you have already moved on and this has all become a strange memory.

As long as you are moving forward, it is the right way forward. Try to stay busy. Consider joining a local activity group of some sort. If you find yourself orienting your mind or actions back toward them, understand that it is because you still have an emptiness and you are seeking comfort from it through old behaviors that will now only make it worse. No one knows what will fill it one day, but something or another will. You just have to keep walking until you reach that destination.

Pro75357, in What would happen if we put a giant glass tinted dome over each city?

There are probably better ways to block out the sun. Glass is heavy and would cause a lot of problems. Something that floats high in the sky would be better, but it would unfortunately move with the wind and weather. If you could get something big enough to space, in a geosynchronous orbit, it just might work…

ChemicalRascal,
@ChemicalRascal@kbin.social avatar

A large swarm of satellites, forming an adjustable solar shade, sitting around L1 for Earth-Sun is likely the best approach we would have. The swarm wouldn't be in a geosynchronous orbit, though, but instead a heliosynchronous one.

Unanimous_anonymous,

Wouldn’t anything sizable enough to make a noticeable difference immediately act like a solar kite and be wisked off into space, L1 or not? They’d have to all have force sources(ionic engines or something) to counteract the force. I wonder how practical something like that would even be on something of that scale. Interesting to think about.

ChemicalRascal,
@ChemicalRascal@kbin.social avatar

Whisked off into space by what, exactly?

CopernicusQwark,

Solar wind

ChemicalRascal,
@ChemicalRascal@kbin.social avatar

Solar wind is not going to just yeet stuff around like that. It'll have some sort of impact, but it's not like, you know, actual wind.

CopernicusQwark,

For something that is positioned at L1 for an indefinite amount of time, with a large enough area to be effective as a solar shroud, it'll definitely have an impact.

That kind of shroud is effectively a solar sail without the ship attached.

HatchetHaro, in Do you prefer PC or laptop?
@HatchetHaro@lemmy.blahaj.zone avatar

If you only use your computer for the most basic of operations (browsing the Internet, watching Netflix, writing documents, etc.), Chromebooks are fine. However, I’m assuming this discussion is about laptops versus desktops.

Basically, all you need to care about between laptops and desktops is the balance between portability, power, and affordability. If you travel a lot, get a laptop. If you need the processing power for video editing or gaming, get a desktop. If you need to edit videos while traveling, get a gaming laptop. If you don’t need any of those, get a second-hand Dell desktop.

If you need to use a laptop but hate the keyboard and trackpad, nothing is stopping you from chucking a separate mechanical keyboard and a mouse into your backpack. A lot of people in tech actually just do that.

ArtieShaw, in Do you have a sibling? What is the relationship like?
@ArtieShaw@kbin.social avatar

I have a brother who is younger than me by 6 years. Our upbringing was a bit weird. Our parents basically forbid anything that might cause them inconvenience, irritation, or expense - which was most things that might interest a kid. (No, they're not religious, which is the first question that everyone asks. They're just raging assholes who are also a bit stupid. I can't really explain it much beyond that.)

In addition to the manipulation and emotional abuse, they rewarded us if we informed on each other. I seldom did. Not through any great virtue or integrity of my own, but because I routinely got punished for the stupid shit he did. For instance, I didn't tell them when our adult neighbor shot little bro with an air rifle because I knew he would catch absolute hell for being in the position of getting shot with an air rifle. Even if I didn't catch hell about it, it was miserable to watch him get screamed at. For context on this story - we had been told to stay away from Steve's yard because Steve was a known psycho with a hatred for neighbor kids. On that glorious summer day, Steve had dropped a $5 bill on his driveway just inside the property line... and was waiting for a kid to come by and be dumb enough to try to pick it up.

I might actually tell that one at their funeral.

By contrast, bro was younger and never got any blowback if I was doing something wrong. He actually recorded me talking on the phone with a friend when I was in middle school. He picked up the other line and held one of those shitty '70s tape recorders to the earpiece. Talking on the phone was forbidden and he was collecting proof to use against me. My friend and I weren't plotting shit, I wasn't grounded (the concept was foreign because we were never really allowed to go out or do things like talk on the phone anyway), it was just forbidden to talk on the phone.

I could excuse it when he was eight, but he passed along "dirt" on me well into his late teens and my twenties. He was under pressure from them as well, but he basically shredded any idea of trust between us for far too many times to count. I forgot what the final straw was, but I remember thinking, "I can never confide in this person and feel trust." In every meaningful way, I've ignored him for the last 20 years.

He's probably the least shitty thing about family gatherings, but that's not saying much.

proudblond,

Man I feel for both of you in this situation. Obviously he could have made a decision at some point in his life to stop being shitty, and he didn’t, so that’s on him and I don’t blame you one bit for not having a relationship with him (or much of one). But I can also imagine a kid with really shitty parents who gets “rewarded” for essentially alienating their older sibling in this manner, so he does that in the hopes that it will strengthen an otherwise toxic bond with the parents. Which of course it really doesn’t, but no kid is going to understand that. Any kid wants good parents who love them. Oh man, I’m so sorry, for both of you but mostly for you.

mathlad,

Wow, your family and your neighbor are such asshole people. I’m glad you are out of there.

Peruvia, in Getting Over a Breakup
@Peruvia@lemmy.ml avatar

I’m very sorry you’re going through this. Someone broke things off with me and it still hurts, even if it has been a while. The first month was the hardest, then it gets easier bit by bit. What helped me was keeping busy with work, I had a lot going on to keep me distracted. I tried to do things that I didn’t do before, or that I wanted to try and never got the chance to do, or stopped doing when I got in the relationship. I found it important to try to enjoy my solitude, but that takes time. Go places, even if it’s very near you. I delved into my hobbies to keep my mind off of it. If you can, try to process things bit by bit, just don’t try to escape your feelings in the long run, that fucked me over(It’s been a while since I avoided processing my former relationship so yea).

Redpandalovely,
@Redpandalovely@midwest.social avatar

Yeah, we can’t escape feelings forever. I guess it’s just tough to understand why I have to go through so many difficulties in life.

Reil, in How can we improve Lemmy’s SEO so we can google “(question) lemmy” instead of relying on “(question) reddit”

It’ll happen if Lemmy gets big enough. I only worry about search engines getting tangled in the natural duplication of Lemmy posts.

Like, if a web crawler sees a Beehaw post, and then seees Lemmy.ml’s mirrored page of that same post, could it just show up as two different results? Could it work against the SEO in that it gets marked as “duplicate” or “spam” content in some way?

ComradeKhoumrag,
@ComradeKhoumrag@infosec.pub avatar

It might help it, as well. I believe in the Yandex source code leak they detail their algorithms SEO techniques. Might be a good lead

evatronic,

If/When Lemmy and other federated services grow to the point that’s an issue in major search engines, said search engines should be smart enough to group and/or suppress mirrored results.

You can see that sort of thing in Google now for major sites like Reddit and StackOverflow, though it’s more along the lines of “the same question in a different post”.

You can also, in the interim, just pick an instance and add, site:lemm.world or whatever instead of just “lemmy”.

The ideal solution is that the page has a canonical tag, telling search engines what the main URL for the content is: ahrefs.com/blog/canonical-tags/. I don’t know if Lemmy already does this, nor do I know how well canonical tags work cross-domain as I’ve only ever used them for content on the same domain.

I checked and it does, this post’s canonical is:

<link data-inferno-helmet=“true” rel=“canonical” href=“https://merv.news/post/26663”>

Weirdly it uses OP’s instance, in this case merv.news. Shouldn’t it be the instance where it was posted?

ClassyHatter,

Canonical tags were added in 0.18.2.

AdmiralRob,

I would think it’s because users only interact with their own instance. They would need to post it to their instance first before it can be forwarded to the appropriate community’s instance.

arthur, in What are some useful or just cool stuff to memorize?

Do you remember the Fibonacci sequence? You can use it to convert miles to kilometers .

2 mi ~= 3km

5mi ~= 8km

8mi ~= 13km

13mi ~= 21km

And so on.

soggywhale,

That’s awesome thanks !

DoctorWhookah,

Wait, is this true until its not or is it true forever as you go higher in the sequence?

masochismworld,

Conversion factor of miles to kilometers is about 1.609 and golden ratio is about 1.618, it will be pretty accurate for quite a while…

liam_galt,
@liam_galt@lemmy.blahaj.zone avatar

It’s true forever. The Fibonacci sequence used in this way converges on the golden ratio, which is close to the conversion of km and mi.

Anticorp,

So are you telling me that the inventors of the mile were using the golden ratio?

Maya,

We wish they were that cool, the inventors of the modern mile were more concerned about land measurements. A square mile is 640 acres. Which neatly can be cut into quarters 3 times. 160, 40, 10.

arthur,

Just a neat coincidence

kakes,

Someone already replied with a graph, but I also got curious and checked for some higher numbers. Sure enough, it held up.

For example:
832,040mi => 1,346,269km (actual: 1,339,039km)

snek_boi, (edited )

I think the way to formally prove this is to find the difference between the Fibonacci approximation and the usual conversion, and then to find whether that series is convergent or not. Someone who has taken the appropriate pre-calculus or calculus course could actually carry it out :P

However, I got curious about graphing it for distances “small enough” like from Earth to the sun (150 million km). Turns out, there’s always an error, but the error doesn’t seem to be growing. In other words, except for the first few terms, the Fibonacci approximation works!

This graph grabs each “Fibonacci mile” and converts it to kilometers either with the usual conversion or the Fibonacci-approximation conversion. I also plotted a straight line to see if the points deviated.

https://lemmy.ml/pictrs/image/528b1166-8b5d-481d-a7bc-180947c29520.png

Edit: Here’s another graph

https://lemmy.ml/pictrs/image/003c6f1a-5555-45d3-a4d6-e4b5ddae71ec.png

So it turns out:

  • Fibonacci-approximated kilometers are always higher than the usual-conversion kilometers
  • At most, the difference between both is 25%. That happens early on in the terms.
  • After that, the percentage difference oscillates around a value and comes closer to it.
  • When talking about more than 100 miles, the percentage change approximates 0.54.

TL;DR:

  • Yes, the Fibonacci trick is true forever as you go higher in the sequence if you’re willing to accept a 0.54% error.

If someone wants to play around with the code, here it is.

Note that you need RStudio and the Tidyverse package.

Mmm dat ggplot2 but ggthemr::ggthemr(“flat”) is where it’s at.

snek_boi,

Checked it out and love that package! Thanks for the recommendation :)

kogasa,
@kogasa@programming.dev avatar

The ratio of consecutive terms of the Fibonacci sequence is approximately the golden ratio phi = ~1.618. This approximation gets more accurate as the sequence advances. One mile is ~1.609km. So technically for large enough numbers of miles, you will be off by about half a percent.

abejfehr,

It’s always true because the ratio of miles to km is really close to the golden ratio.

If you do it for a zillion miles you’ll be off by a lot of km, but proportionally the same amount as for 1 mile

I stopped talking to mine when he went batshit because I wouldn’t help him get onto Tor/darkweb. He wouldn’t say why he wanted to access it, and he got angry when I said I didn’t want to get involved.

Then he accused me of being a “tony blair lover” which is kinda bizarre to me because I don’t live in the UK anymore.

It was a very strange interaction!
