I've taken to telling them that someone else helped me out, and I'm just trying to pay it forward, with interest. If they can pay it forward in future, I would be very happy with them continuing the chain.

You still get the dopamine of a good deed, they feel like they can pay you back by passing it on. If they don't, no harm done. If they do, your good deed just got amplified to some other poor sod's benefit. It might even loop back!

It's quite difficult to retroactively adjust the traffic speed, without causing knock on issues.

A road might have been designed to cope with 50, but hidden junctions, or pedestrians might knock it down to a 30. Making it feel like a 30 is quite different.

I'd personally prefer other, more polite methods. In the UK, the signs showing your current speed in either green (good) or red (too fast) are remarkably effective. I accept that speed cameras are needed when the other methods fail.

Proviso, the cameras should be blatantly obvious, with no ambiguity over the limit. It should only catch people both deliberately speeding, and not paying enough attention to spot the risks of speeding.

Basically, an "instant" communication device can create paradoxes.

E.g.

Earth sends mars a instant message. Mars the relay's it via normal radio to a passing ship/probe moving at 0.99C. That probe then sends an "Instant" message to Earth.

The final message will (depending on alignments etc) arrive before the original was sent. If the message the voids the reason for the original message to be sent then a paradox happens.

You can make similar things happen with any form of FTL communication. C isn't technically the speed of light, it is the speed of information. It just happens that light has no other speed limiting, and so moves at maximum speed.

ADHD could have some bearing, if it was something quick and impulsive. Premeditation makes it even more damning however.

Either way, it's not an excuse, just a factor to account for in corpus mentis decisions.

Desensitization to guns in c/whitepeopletwitter@sh.itjust.works
[–] cynar@lemmy.world 3 points 4 days ago (1 children)

I'm not saying the USA should just disarm its police. I was more pointing out how fucked up gun culture has made it. Most UK gangs don't have guns. The risk reward balance doesn't justify them. Any gang that does try to escalate with guns becomes the focus of a LOT of police attention.

[–] cynar@lemmy.world 11 points 5 days ago (3 children)

Years ago, the UK government announced they were going to arm the general police. The people with the biggest issue with it was the police union!

The UK has a police by consent basis. The heaviest firepower they carry is a tazer. If there is a risk of guns being involved, the normal police pull back and call in the armed response officers. When they do, however, they call the whole cavalry!

End result, criminals don't feel they MUST have a gun to defend from the police. Conversely, going in armed will bring the whole, focused weight of the armed response down on you. (As in multiple helicopter level searches) Most don't carry guns, and so the status quo keeps everyone safe.

How come assassinations went away for the most part? Why send a bunch of god fearing young kids into a battle the upper class started or wanted when clipping one leader would stop it? in c/nostupidquestions@lemmy.world
[–] cynar@lemmy.world 7 points 5 days ago* (last edited 5 days ago)

I'd argue they didn't, they just changed.

There are 2 groups worth noting. Government and private.

Government assassination is still a thing. Israel has used it aggressively over the last few decades. There are also signs that china has too. That's just off the top of my head. It's also worth noting that drone strikes etc can fill the same roll as an assassin.

Private has definitely changed. I suspect the high profile assassinations have stopped. Low level ones just had to get a lot better at not looking like assassinations. The ever classic boating accident being a good example.

The change is mostly from improvements in policing. You can no longer just move to another city to escape the law.

It's also worth noting that a lot of society has changed. It used to be that a country pivoted on its leader. Now, it's a lot more reliant on formal structures. Taking out a leader doesn't have the same, devastating effect it used to. Iran being a good example.

Is there a more rage-inducing sign? in c/micromobility@lemmy.world
[–] cynar@lemmy.world 4 points 6 days ago

There's a couple near me. 1 on an arched footbridge, on a busy pedestrian path. The other on a narrow, cut through. It's near a school and people turn into it around a blind corner.

I consider both completely reasonable things to ask.

Lasers, or, The effects of overhyped technology in c/curatedtumblr@sh.itjust.works
[–] cynar@lemmy.world 19 points 6 days ago (1 children)

Lasers are both coherent (all the photons line up) and monochromatic (all the photons have basically the same energy). This makes them very easy to focus to a small point and/or make directional.

Diode lasers are effectively LEDs, tuned to these properties.

Lasers let you get a lot of power down a VERY small hole. They also allow you to send multiple colours down the same fibre, multiplying its bandwidth.

You know you didn't know about the loop initially. Therefore, something you did without that knowledge caused it. Making changes, based on the new info will change the outcome to something different.

You wouldn't just turn around without cause in the original loop. Doing so, with your only reason being the new knowledge will change the outcome.

[–] cynar@lemmy.world 0 points 1 week ago

Agreed on that. Though in the scale of the UK there aren't that many cases. The ones there are however, are (deliberately) high profile. It has a chilling effect on the population, without needing to use it much.

They also hamstring the bobbies via the budget assignments. I know a lot of forces would love to get rid of some of the more overtly racist/sexist/other-ist officers. Their budget limits wages however, which limits the selection of replacements. They end up having to try and weed out the ringleaders (to fire or retire) and split the followers up.

The long and the short, most of the police are working class and do the job to try and make our country better. Some are even trying to counter the bullshit rolling down from on high.

That episode bugged me. You find yourself in a time loop. It's looped enough times for you to detect it.

"Let's not change anything."

... WHY?

Turn around, fly away and contact someone. Launch a probe from a distance. Change the loop, so it doesn't loop!

Hi all.

My venerable ender 3 has likely printed it's last benchy. Plus side, the tech has advanced significantly since I bought it. Down side, I've not kept track of the newer options.

Can anyone give me a rundown of which are worth looking at, and which to avoid?

I'm mostly concerned with reliability, but a speed boost would definitely be welcome. A heated chamber and/or multi material would also be very nice to have.

I would like to keep the costs closer to £500 ($680) but can stretch that, if there is a machine worth it.

I also have a complete no on bamboo printers. I don't like what they've done regarding abuse of the open source movement.

Thanks all!

Edit to add. I'm not against non open source printers. I just have an issue with companies trying to burn the ladder behind them and lock their customers into a bubble.

Double edit: The snapmaker U1 seems like my best option. Ticks all the boxes, while remaining well in budget.

Robot Lawnmowers (lemmy.world)
 

Does anyone have much experience with robot lawnmowers? I've been considering one, but trying to find info now involves digging through a lot of AI slop.

Id prefer one that plays nicely with HA, as well as not internet dependant. It's also for a small garden (50m²).

The best bet I've seen so far is to modify a yardforce mower with open mower. What other (good) options are there?

Damage resistant shoes (lemmy.world)
 

My daughter (6) is aggressive abusive to her shoes. Trainers seem to last about 6 weeks before the toe is destroyed and the sole delaminating. Sketchers, or boots seem to last a bit longer, maybe 2-3 months before being annihilated.

Has anyone found a brand or range that actually holds up to the abuses a small child can throw at them? I've reach the point where I'm eyeing up composite toed builders trainers. That seems overkill however, and she doesn't like the designs available in her size (UK size 2/3).

Has anyone else ran into this problem and found a viable solution? It's getting both expensive and embarrassing. Oh, and before it's suggested, my wife has vetoed the boots from a suit of armour.

What are your jokes for younger children? (lemmy.world)

My daughter is 5 now. She's discovered the joy of telling jokes. Unfortunately, her repertoire is painfully small. I've also realised most of my jokes are either not age appropriate or too situational.

What are best/worst kids jokes? Extra points for any that would make her teacher groan. Apparently she LOVES jokes. 😁

Kids Tablet recommendations. (lemmy.world)
 

I need some advice, and the amount of marketing spam had made sorting the wheat from the chaff annoyingly difficult. Hopefully you can help.

I've a young daughter, who uses an old tablet of mine to watch netflix etc. unfortunately, it was old in the tooth when she was born, and it's now become extremely annoying to use.

She currently has a Samsung Galaxy Tab A (2016). The size (10") works well, but it's gotten slow as sin, and only has 16Gb of internal memory.

Preferences wise:

  • 10" screen (±2")

  • 64Gb+ storage.

  • Long expected lifespan (inc security updates).

  • Headphone socket (adapters are asking to get broken, Bluetooth go flat)

  • Decent WiFi (more than just 2.4Ghz).

  • USB C charging preferred.

  • Wireless charging would be very helpful but not required.

  • Lower budget preferred (£200 range).

What would people recommend?

Low cost Zigbee GU10s via Ikea (UK) (www.ikea.com)
 

For those of you in the UK, IKEA currently has a steep discount on their GU10 bulbs. I've just picked up several dimmable, colour temperature controlled bulbs for £5 each.

They play nicely with HA via a sonoff dongle and ZigBee2MQTT, even down to firmware updates.

Recommended linux variant for gaming. (lemmy.world)
 

I've been using Ubuntu as my daily driver for a good few years now. Unfortunately I don't like the direction they seem to be heading.

I've also just ordered a new computer, so it seems like the best time to change over. While I'm sure it will start a heated debate, what variant would people recommend?

I'm not after a bleeding edge, do it all yourself OS it will be my daily driver, so don't want to have to get elbow deep in configs every 5 minutes. My default would be to go back to Debian. However, I know the steam deck is arch based. With steam developing proton so hard, is it worth the additional learning curve to change to arch, or something else?

Custom Spec Laptop (lemmy.world)
 

I'm upgrading to a new laptop (unfortunately, a desktop is not viable for me right now). It's a VR gaming machine, with some potential work with machine learning (me learning about it). I've got a system option, but it's into price flinching territory, and wanted a once over, from those more in the know.

Are there any obvious flaws in it, and is it reasonable for the price?

  • Display: 1 x 16.0" IPS | 2560×1600 px (16:10) | 240 Hz | G-SYNC | 95 % sRGB

  • Graphic Card: 1 x NVIDIA GeForce RTX 4080 Laptop | 12 GB GDDR6

  • Processor: 1 x Intel Core i9-13900HX

  • Ram: 2 x 16 GB (32 GB) DDR5-5600 Samsung

  • SSD (M.2): 1 x 1 TB M.2 Samsung 990 PRO | PCIe 4.0 x4 | NVMe

  • Keyboard: 1 x Mechanical keyboard with CHERRY MX ULP Tactile switches

  • WLAN: 1 x Intel Wi-Fi 6E AX211 | Bluetooth 5.3

It prices up at €2,809.31 (£2,484.57 or $3,130.80) including shipping and taxes.

It's worth noting the system comes with an optional external water cooling system, so the CPU and GFX are less thermally limit, when it's plugged in. It also has a proper keyboard, not the normal membrane ones.

What are people's opinions? It is a reasonable price, or am I way too far up the diminishing returns slope?

Fixed address WS2811/WS2812b clones. (lemmy.world)
 

My Google-fu has completely failed me. I've got an RGB addressable led curtain. It has 20 strings of 20 LEDs in a square arrangement. I initially assumed it had a wire feeding led data back up, to go to the next drop. On checking however, they are T jointed.

Apparently the address is hard coded into the RGB controller in the LED. I've found a few places where others have talked about them. I've also found that adafruit had some available,, unfortunately they lacked any info on how they are programmed, or where to source them from.

Anyone got any info on what the chip name of these is? Even better if you have any info on how they are programmed etc!

Printer recommendations (home colour laser). (lemmy.world)
 

Might not be the best place to ask, but nowhere else reliant seemed alive.

My old laser printer has given up the ghost. What are people's recommendations on a replacement. As far as I'm aware, Brother are about the only company both making reasonably priced printers and not playing stupid games. Beyond that though, I'm not up to date on what's good and what's not.

Requirements.

  • Colour laser.

  • WiFi

  • Works with both windows and Linux

  • No need for scanner etc.

  • CD/ID card printing nice, but not required.

  • Photo quality nice, but not required (we have an ink sublimation printer for photos).

I'm UK based, which can mess with availability.

Thanks in advance.
