WhyJiffie ,

Doesn’t help with the bloated web and local webapps, though. Also, you’ll need to choose from a set of desktop environments that were made with lower resource usage in mind. Also don’t forget that while linux is often faster, a slow drive is still a slow drive and it can help only so much if you keep your OS and heavyweight software on a HDD.

Radioactive contamination: things don’t transfer the property of radioactivity to everything they touch and/or irradiate. If that were the case, the entire Earth universe would have become radioactive gray goo long, long ago.

When radiation workers talk about “contamination,” we mean radioactive compounds have physically transferred from one object onto/into another. For example, tools becoming contaminated with radioactive metal dust from equipment they touch, or clothing absorbing radioactive iodine gas from the air.

There is a form of radiation called neutron radiation that does make some formerly stable things (mainly metals) radioactive. This isn’t something you’re likely to encounter unless you’re a specific type of radiation worker, however.

This is mainly gear-grindy to me because the reason we don’t have gamma-sterilized produce in the US is completely unfounded fear that gamma irradiation “contaminates” everything it touches. So we could be having lovely fresh strawberries and peppers that last weeks longer than they usually do, but no, we can’t because rAdIaTiOn ScArY 🙄

niktemadur ,

Physics/nuclear literacy in the general public around the world is lower than bad, even many scientists from other fields seem to be genuinely uninformed or misinformed, then posting wrong and often alarming interpretations in social media, which laymen give weight to because “it’s coming from a scientist”, never mind that their expertise may be in areas of biology or astronomy, nothing to do with the subject they are posting about. And they themselves might have gotten their bad info/interpretation from other figures in academia.

Now that you mention it, it does make sense but I never t thought that you could sterilize food with radioactivity.

It is called cold pasteurization, seen some things labeled as such before.

overcast5348 ,

What about contamination in disaster sites like Chernobyl or Fukushima? Is that also mainly radioactive substances that we’re spread around the area by air/water making the whole place dangerous to live or are other previously-non-radioactive objects radioactive now?

janus2 ,
@janus2@lemmy.zip avatar

The former, unless those disasters also included neutron radiation (admittedly I don’t know much about either disaster)

dgmib ,

Yea basically the main contamination issue is that radioactive substances were spread around. Contamination of the surrounding area isn’t the only issue we have to deal with, nor is it the most serious, but it is generally is the most costly remediate.

The contamination problem is caused by radioactive matter spewed into the air and settling on the trees, buildings, ground etc… in the surrounding area.

The main remediation strategy is to remove everything in the surrounding area including the top ~3 ft or so of soil of the and haul it off to an underground landfill to slowly decay for at least a few hundred years safely separated from humans.

I do not literally build buildings. I design them, I document them for construction, I collaborate with other people who do actually build the buildings to make sure everything’s on the level.

rand_alpha19 ,

No, replacing your HVAC or control systems will not magically fix the engineering issues present in your home/building. You will have to compensate for poor design indefinitely unless you want to demolish and start over.

BearOfaTime ,

Oh fuck, improperly designed HVAC + changes made to a building that really fuck it up… There’s no fixing that folks.

“This one room is always hot!” Well, there’s no return, the door’s always closed, and oh, someone replaced the door 20 years ago and now there’s only a 1/4" gap between it and the floor. No, “turning up the fan speed” isn’t going to fix it.

brygphilomena ,

Transom windows. I don’t know why they aren’t common. But they make it easy to close a door but still allow airflow through the house.

toddestan ,

Because modern houses really don’t give any thoughts about airflow or natural cooling. Heck, even getting the AC compressor installed on a side of the house where it doesn’t get baked in the afternoon sun is too much to ask for.

Cataphract ,

Do you have any suggestions for those interested in learning about HVAC design principles? I’m currently far enough along in experience where I’ve discovered I know very little because of how complex each part of the systems can be. I’ve ran into so many questionable setups doing inspections but would love to be able to look at a unit’s specs and follow the runs making sure nothing immediately eye-catching is going on.

I have similar experience with Electrical and Plumbing, 99% of the time it’s common mistakes made by installers or not following code properly. HVAC is near impossible to fully grasp because of the code terminology and arguments over best practices. Even something as simple as a range hood gets people confused because of the exhaust type versus code requirements.

CuriousRefugee ,

Space is hard. You’re strapping something inside a big tube with basically directed explosives at the bottom, hoping it survives the trip, then subjecting it to constant radiation, huge temperature swings, and other brutal environmental factors like micrometeoroids. Just because we’ve been sending satellites and people up to space for nearly 70 years doesn’t mean it’s gotten easier; we’re just better at knowing what to expect so we can test for it. Failures in rockets or satellites or even manned spacecraft are going to happen as much as we work to prevent them.

Medicine is not an exact science. Every human body is different and will react different to treatment or show different symptoms.

That your doctor couldn’t diagnose you right away or a treatment is not working for you as wanted (or as it did for your neighbor) has most often nothing to do with the competence of the medical personel but with the fact, that your body is not a massproduced machine but 100% unique a änd individual biological mass.

smb ,

that is only partly true, health system (here) also proposes to make false diagnoses for making money while the really needed treatment is underpayed or not payed at all or - in some cases - not payed at all if some facts change “after” the diagnosis so that the involved doctors spent time and money while afterwards not beeing payed at all. doctors doing false diagnoses (here) are mainly following the systems suggestion to skip real treatment but instead abuse patients.

norimee ,

That is a pretty big accusation you are putting on health care professionals.

Of course the cost often is a deciding factor on what treatment is possible. I’ve seen this in european hospitals as well, that we couldn’t run certain diagnostics or give certain medications because they were too expensive and would mean the hospital spends more than it gets for the patient.

But what you are saying is that doctors and in consequence nurses, medical technicians and all kind of medical staff are all in on a conspiracy to MISDIAGNOSE ON PURPOUS (!!) causing bodily harm (again on purpous) to their patients in order to get payed by insurance?

Please provide reliable sources and proof for this accusation of significant criminal activity that is apparently the norm in your (“here” means the US I assume?) Health care system.

I understand that your health care system is wack. But the fish stinks from the head and that’s usually not the medical staff providing your care, which you are accusing of serious crimes here.

smb ,

i did say that health care professionals follow suggestions which is 100% true for the suggestions they get from (known health damaging) pharma corporations. and these suggestions are mainly for profit. maybe let me note the opioid crisis here, that did not even touch my country directly (that is until this becomes officially maybe), but assumingly yours. if you don’t know what happened there and who followed who’s suggestions, maybe start reading. same happens in other countries too and for the same purposes.

a fact that is official here (as in there was a need for a law that currently helps) is that you get different diagnoses from different doctors and NEED to go to at least two different ones to have a chance for a correct diagnose. it took me >30 years to find a doctor that also tells me what is maybe less probable but also maybe a correct diagnose. the others just ignored all facts that were noncomplient to their diagnose and either were silent about it or incapable of also assuming other things with slightly similar symptomes.

the system is that prone to do wrong diagnoses while not paying for real treatment that some patients and doctors silently agree to do some extra things that are paid better to finance the things that are not paid in one go as a compromise to circumvent the harmful system. this is not public as in news, but when you go to a doctor that you know and need something that is not paid and offer something else at the same time that actually gets paid like a scan for something that could be important for symptoms you might have, chances are very good to get better real help than when strictly following the laws without such offers. i’ve talked about this with a doctor where i was not patient and i observed this once from little distanze.

i did not say that healthcare professionals intentionally harm for profit but follow guidelines made for profit-only that cause harm.

also maybe ‘interesting’ to read: …bmj.com/…/time-to-assume-that-health-research-is…

i tend to say that some shamans with true intention to help might often be better than a socalled healthcare system that truely is based on profit-only directors. while healthcare professionals depend on intentionally wrong informations (see opioid crisis) from profit-only corporations, their actions effects can highy contradict what their true intentions are. but for patiens really the outcome is what counts.

so even if someone says that treatment from healthcare professionals harms the patient this does not at all include evil intent from that professional.

Halosheep ,

smb ,

xilona ,

And now I am thinking how the mrna “vaccines” must have worked for every person or else…

Buddahriffic ,

The mRNA itself would behave the same from person to person. The immune response and specific cells that get “infected” can vary.

The immune system works to produce cells that can produce antibodies that bind well to the antigen, the specific part that they bind to can be different from person to person. The immune system tries to avoid antibodies that also bind to other things, but it’s not perfect.

If the injection ends up getting into a vein, then the mRNA could infect heart cells, which then later get killed by killer T cells and can affect heart function in the short term. Or potentially, they could end up anywhere in the body before entering a cell.

But, the same applies to the actual virus, only to a higher degree.

When you have a live virus infection, the immune system has the full virus to target with antibodies, so the variance will be higher compared to people only getting a subset of the virus, and has more chances to overlap with things we don’t want our immune system targeting.

And a real viral infection generates copies of the virus to spread to other cells instead of just producing proteins that the immune system will target. It’s like getting another vaccine shot every time the period it takes to produce more virus copies passes, from the moment you get infected until your immune system manages to get the upper hand (though distributed very differently).

It makes sense to be wary of new things you’re advised to put into your body, but it’s also important to frame them correctly. It’s not just risk of vaccine going wrong vs no vaccine means no risk. It’s risk of vaccine going wrong plus risk of infection breaking through times risk of vaccinated infection going wrong vs risk of getting infected times risk of unvaccinated infection going wrong.

EnderMB ,

I remember my university orientation so vividly, because I was sat next to several people that were taking the “Game Development” degree. They spent the entire orientation talking about what consoles they brought with them.

Two weeks later, they were all gone. The course was arguably harder than my CS course, based on some of the required classes they had to take. I think the dropout rate over the full degree was ~90%. CS was high, sure, but barely anyone actually graduated with the Game Development degree.

Game dev is hard, and I’m yet to meet a game dev that didn’t bemoan how utterly ruthless it was.

wreckedcarzz ,
@wreckedcarzz@lemmy.world avatar

Though it being difficult doesn’t excuse releasing an untested program or one with known issues…

KeepFlying ,

Sometimes you have to make a tradeoff and focus on the golden path, which means comprehensive testing has to be skipped or bugs have to be explicitly left in.

Yes it’s bad. Yes it sucks. But it’s that or nothing gets released at all.

(I wish it wasn’t that way. I try hard to make sure it isn’t that way at my job, but for now that’s how it is)

hperrin ,

Known issues that don’t interfere with the critical user stories are usually not prioritized. They should be disclosed, and even better if workarounds are published, but fixing them usually isn’t in the budget.

intensely_human ,

Since February the Uber Driver app has had a bug where elements from the “not in a trip right now” UI state render over top of the “in a trip and navigating” UI state.

It means that the user can’t see the text for the next turn, and also can’t see the direction of the next turn.

However there’s a workaround because they can see the distance to the next turn and once they’re close they can see which way route line goes.

hperrin ,

I would still say that interferes with a critical user story.

Copythis ,

Sometimes your printer won’t print in black and white if a color is out because it uses all of the colors to create a deeper black. Depends on the model though.

And some of them use yellow as a lubricant because yellow toner has a consistency close to water.

Also, please do not copy money or your butt. Trust me.

I have had a “biohazard” call at a local college.

The platen glass is a lot thinner than it looks!

Also, depending on the model of the copier, it will not let you copy money, and if you attempt it too many times, it will literally brick the machine.

Something cool to do is to take your phone and turn on the selfie camera. Lay that on the platen and make a copy to see a trippy pattern.

If you want to screw with someone, lay a single paperclip on the platen and make a bunch of copies of it. Take your copies and shuffle them into the paper tray face up (assuming you’re using an office laser copier) so every once in a while, someone will get a paper clip on their print.

The speed of the conveyor belt does not impact the cycle time. No you cannot fucking slow down the conveyor belt to make it so you can work slower. You can’t speed it up to make people work faster. The speed of the fucking conveyor belt determines how long the things stay on the fucking conveyor belt. If it’s too slow things just stack up on it

Sorry, fucking line workers, managers, and executives in a factory…

Buddahriffic ,

An analogy to thinking faster conveyers means faster production is thinking faster speed limits on the highways leads to higher reproduction rates (or faster graduation or whatever).

One thing it will affect is how long a part takes to go from initial production to release. But there’s a trade-off with how many products are “in fight” at once.

Actors don’t “act”

90% of an actor’s work is preparation (memorization is just a tiny part of this- a big part of it is studying the scenes and figuring out the character’s realizations and decisions)

By the time you’re performing, you shouldn’t have to think about the scene or dialogue at all, but just connect with your scene partner and let them guide you through it. Acting isn’t about you. You’re not important, it’s about the moment that’s in between you and the people you’re performing with.
