As others have stated, replace your air filter if you haven’t recently. Make sure it’s the appropriate size and rating. It should probably be pleated, and the MERV rating shouldn’t be too high unless you know the fan supports it.

Use a temp gun or a kitchen instant read thermometer and compare the exhaust temp vs the return temp. It should be around 15 degrees difference or more. If it’s not then an installer should adjust the pressure on the system.

If you have multiple floors you may have a vent damper for summer vs winter. In the winter the dampers may be set to help force air through the lower floor vents and prevent the hot air from rising too fast to the upper floors. If the installer or previous owner was nice the damper will be labeled for summer vs winter.

If it’s not blowing air at all, then you may have a leak or a blockage.

If theres ice on the indoor coil or on the lines outside then either the filter is clogged or your pressure is off.

If your hvac person is telling you it’s working fine and it obviously is not, call a different installer.

pkill , to KDE in cant wait for plasma6

will it be lighter on the CPU?

Seems unlikely it can get any lighter than the 0.14% CPU load average 5.27.10 is using right now

pkill ,

hmm strange, maybe some applet but when I was using it on my 3rd gen i7 laptop it never went silent and the CPU usage could spike to even 20% when idle

ozymandias117 ,

Maybe something wrong with the GPU in your setup?

I could see kwin using a lot more CPU if the compositing fell back onto software rendering instead of hardware rendering

Even a 8th gen i7 struggles to keep cool and quiet compared to Ryzens from 2019 onwards running the same stack

Gondolaaaa ,

I’d go with some applet as the culprit. I use a Haswell i7 laptop and it’s quiet

Plopp ,

I run Plasma 5 on a 2nd gen i7 laptop and it’s idling just fine and quietly most of the time with no such spikes unless I have several apps running, including a web browser with a plethora of tabs.

Is it wise to allow a 3 yo to use computers?

I’m not an expert by any means,but digital autism is no joke. This is just too much for their developing brains.

Daxtron2 ,

“Digital Autism” is not supported by current research to be a real thing. Autistic children are more likely to be attracted to technology as a substitute for social interactions though.

jamanetwork.com/journals/…/2812722

hornedfiend ,

I do hope this had been understood as an IMHO,as usual with there sort of comments.

Interesting conclusion though:

" The results of this systematic review and meta-analysis, including a notable indication for publication bias as well as small and sometimes nonsignificant effect sizes, and the limitations just described suggest that the issue of screen time and ASD is far from being resolved. In fact, the slight superiority (although not statistically significant) of the clinical diagnosis variable over the ASD symptom variable we observed in the meta-regression brings forth the basic obstacle in this field, which relates to the directionality of the association, as discussed at the start of this work. Alongside the displacement hypothesis focused on the potential negative outcomes associated with screens, a large portion of the literature is dedicated to the opposite direction—that is, to the characteristics that draw children with ASD to engage in screen activities.16-18 As concluded in a previous literature review on this topic, children with ASD seem to “show increased interest in screen viewing… [which] begins at a very young age.”18(p308) It is also reasonable to assume that parents of children with clinically diagnosed ASD adopt a relatively permissive position regarding their children’s screen use. It is possible, then, that the observed (bidirectional) association of the current meta-analysis reflects this tendency of children with diagnosed ASD, at least to a certain extent, thus requiring us to continue searching for other explanations for the increasing global rates of ASD. Excessive screen time may indeed come at the expense of positive real-life activities and close familial relationships that could increase ASD risk. However, further research is needed to support this concern, as the increase in ASD prevalence may be attributable to a range of medical, environmental, and societal factors. "

This "Excessive screen time may indeed come at the expense of positive real-life activities and close familial relationships that could increase ASD risk. " still supports my original comment.

Thank you for providing this by the way,but it’s still a debatable topic,with no real conclusion other than it needs more research.

“Excessive screen time may indeed come at the expense of positive real-life activities and close familial relationships that could increase ASD risk.”

You can’t become autistic though. I was born with it, nothing made me autistic.

force ,

Whether you have Autism is entirely cemented before you’re born. You can’t just “get” Autism after your born, although diagnosis may be difficult until a certain stage in development. Same goes for ADHD and other neurodevelopmental disabilities.

Affidavit ,

I think it’s likely that the type of content children are exposed to matters more than the medium. Children who are exposed early to digital technology will have an advantage in adapting to our increasingly digital society over those who are prevented from accessing digital media until they are much older.

@Lettuceeatlettuce@lemmy.ml avatar

I agree. I was grew up playing lots of games like Incredible Machine, Sim City, Zoo Tycoon, Age of Empires 2, etc. They were technical and challenging mentally. Taught me a lot about money management, logistics, testing theories, and solving puzzles.

I also watched a lot of Nat Geo, Discovery and History Channel, (Before it enshitified) read lots of science encyclopedias and books, used the Encarta CD-ROM encyclopedia often.

My siblings and our friends also played outside a lot. Built forts, played paintball, explored the woods, that kind of stuff.

The medium matters much less than the content.

If someone has enough access to your system to covertly use the camera, then the camera is the last thing you need to worry about.

Its not the people with properly-configured networks demanding to be convinced to cover their webcams. Also, our PCs are generally not the devices we’re slapping into DMZs and VLANs with either no LAN access, no internet access, or a bajillion blocked(or whitelisted) ports.

These comments are full of people like you smugly assuring us that “because Linux” and “a firewall” are enough. Lotsa firewalls out there running on Intel chips, and there have been no shortage of other mainstream firewall appliances found to have vulnerabilities and backdoors over the years, nevermind all the cable modems with built-in wifi and SPI Firewalls.

If you don’t know enough to teach your kid basic security practices(all good security, and the EASIEST, MOST CONVENIENT FORMS OF IT - all starts at the physical level - pick up any textbook on the topic), regardless of mitigations you may or may not have implimented, you don’t know enough to be having this argument.

I’d very much expect it to be. The raspberry is pretty much a normal (if a bit slow) modern computer from an application standpoint.

Needs to be compiled for its ARM architecture, thats it. Plasma also highly relies on GPU acceleration, so this also has to work.

SHITPOSTING_ACCOUNT , to Do It Yourself in Spend money replacing? No, DIY!

What glue did you use?

I made a similar repair but with a smaller break using superglue (cyanoacrylate), held perfectly. However, I reinforced the broken part with a piece of a plastic card glued to the side. Consider doing that if this doesn’t hold.

I’d be concerned that the rough surface you seem to have now will be hard to clean and may get very nasty. Other than that, if it works it works.

renard_roux ,

You know where the ‘cyano’ in cyanoacrylate comes from, right? Maybe don’t use it for stuff that touches food/drink… 😳

Lowbird ,

This might be a non-food-bearing shelf, like from one of those rolling plastic drawer sets? I think? It’s hard to tell, admittedly.

SHITPOSTING_ACCOUNT ,

I’m not worried about fully cured CA glue on a non-contact surface of a shelf that holds bottles/milk packs etc., or honestly even fruit whose peel you don’t eat.

Given that CA-based glues are used for wound closure and apparently even as dental adhesives, I’ll trust www.ontariopoisoncentre.ca/…/super-glue/ over the many sites that look like ChatGPT wrote them (mostly trying to sell some food safe alternative). It’s not food safe, so I wouldn’t glue e.g. a soup bowl with it, but eating an orange that sat on a cured seam in a fridge isn’t going to poison you.

renard_roux ,

That sounds reasonable enough 😊👍

Keep in mind that not all CA glues are intended for wound closure, that’s mainly Dermabond/2-octyl cyanoacrylate, which is only “less toxic”, and not for all wound types. Thought it was worth pointing out of others see this 😷👌

wernsting , to Home Improvement in Is there something wrong my AC? It’s a 1 year old unit and it can’t seem to keep up. For reference it is a high of 92 F today

1400sqf = 130m2

Typically in Australia we’d size for 180W/m2 which in a domestic setting gives plenty of heads room.

130x180 = 23.4kW unit. This size it would be a ducted unit to ensure proper distribution of cooling throughout.

2.5tonne equates to approximately 8.8kW which only gives you 68W/m2 which as an ex mechanical engineer is completely undersized at least for Australian summer.

Without knowing more the only suggestion I would give is set the target temperature a bit higher. This increases the units efficiency and should help it get to temperature quicker.

If you’re uncomfortable try running an additional fan. The movement of the air will make you feel cooler even if the air temperature is the same.

metaphortune , to Home Improvement in Is there something wrong my AC? It’s a 1 year old unit and it can’t seem to keep up. For reference it is a high of 92 F today

Has it been working alright throughout the rest of the season? I had an HVAC system that was incorrectly wired by the installers, so it actually ran the AC and heat pump at the same time, cancelling each other out. Might not be your situation but you never know!

Engne OP ,

The air coming out of the vents is cold. In the winter the air coming out is very warm. Would that be the case if incorrectly installed? It almost feels like there isn’t “enough” air coming out of the vents maybe? If that makes sense. Just not a ton of airflow coming out

snooggums ,
@snooggums@kbin.social avatar

That could be part of a problem if it isn't circulating.

Make sure all the vents are open and not blocked by something inside. Switch filters if you haven't recently, and make sure they are the right kind for your unit. If you can get to your duct work, see if it is leaking anywhere as that will reduce the pressure at the vents.

If you have ceiling fans, turn them on to help out. If you aren't already, close curtains to block direct sunlight (east side in the morning, west in the evening).

I would recommend having a different company check it out since they won't be defensive about the prior work.

Brkdncr ,

You can’t “run the heat pump and a/c at the same time” because it’s a single unit. There’s a valve that slides when powered to switch the hot side with the cold side. That’s literally the only difference between a/c and a heat pump.

blinkmepacman ,

You are correct, but they probably have backup electric heat. Heat strips were being engaged along with a/c.
