Nope, it is not.
x = 5
i = 2
x -= i // x => 3
while
x = 5
i = 2
x = -i // x => -2
x=-i is the unary minus operator which negates the value right of it. It doesn’t matter if that value is a literal (-3), a variable (-i) or a function (-f()).
x-=i is short for x = x-i, and here it’s a binary subtraction, so x is set to the result of i subtracted from x.
Find me a language where it doesn’t work like that, and we’ll continue the discussion.
Unary - operator is standard in every single language that I used so far, including C/C++, Java, Python, Kotlin, Lua, JS/TS, Groovy, PHP, Visual Basic, Excel, Mathematica, Haskell, Bash.
Here’s more info btw: https://en.wikipedia.org/wiki/Unary_operation
Why would they not let you do that? I honestly don’t know a single language that wouldn’t let you do that. Same as basic math notation allows you to do that.
x = -i
is a totally valid mathematical equation.
For the downvoters: Find me a single language that supports operators but doesn’t have an unary minus operator
In general, Tree support is easier to remove but has a higher chance of failing. Tree support also only really makes sense if you can get it to go around a part.
So say you are printing a standing O shape. With regular support the support will touch the bottom of the O and will be printed on top of the bottom part of the O, which will make that surface look rougher. Tree support will start sideways of the O and will only move into the O towards the top, so it will not touch the bottom part of the O, leaving it in good condition.
In the case here there’s nothing underneath most of the floating surfaces, so regular supports will be better.
Also, tree support is better when it supports small areas, regular support is better for large areas.
This. No need to realize any gains at all. The same trick also works for any other expenses.
This is a super difficult model. There’s no good orientation for it.
I’d probably print it as oriented on the picture and use a lot of support. If classic support isn’t working for you, try organic/tree support, but I think the regular support would be better. Support should cover the full underside with this print.
When printing in PLA make sure you have really, really good cooling for this.
My sister was like that. We’d always call back “She’s 10 you pedophile”. Shuts people up quite quickly when the call back is done as loud and public as the cat calls.
CAD is obviously something that got much better with better computers, but apart from such heavily PC focussed jobs, I’m not sure this holds true.
Digital systems waste a ton of worker’s time as well, and we now have much, much more bureocracy than before.
In many cases, computers are great at helping you fix problems and accomplish tasks you didn’t have without computers.
Do you always get annoyed at routine questions? Do you get angry when tech support asks you to turn your PC off and on again? Do you get furious when customer support asks you for your order number?
These things are routine questions. The period question is asked by female doctors too. For a reason.
Why is it so hard for you to understand that doctors are just working off checklists that are proven to work? Doctors aren’t there to make nice dinner conversations but to patch you up in the quickest possible manner with the least amount of mistakes. That’s why checklists exist.
If you know better what kind of information a doctor needs than she herself, why do you even go to one?
You choose to be offended because like many people on the internet you live off being offended. “I am offended, therefore I am.”
Well done, you prioritize being offended over being healthy.
What a ridiculous state of being.
If a doctor doesn’t ask and it turns out the patient is pregnant and the treatment harms the embryo, the doctor is liable for the damages. If she or he doesn’t want to be liable, she or he needs to ask the question.
I know someone who had her ovaries removed and was sure she couldn’t get pregnant anymore. Turns out, for some reason the ovary removal wasn’t complete, a small scrap of ovary was missed, and she got pregnant.
Also it sadly does totally happen that women have had intercourse without them realizing. Look up e.g. Gisèle Pelicot.
And lastly, ask how many women are positive that their contraception is in place and working perfectly and can surely never get pregnant but who still end up getting pregnant.
There are women who carry a baby to completion and only realize at birth that they happened to be pregnant for a full 9 months.
Yes, most women know their own bodies. But some do not. And as a doctor not asking is about as smart as putting your hand into a random strangers dogs mouth because most dogs are well-trained and will not bite your hand off.
Not in case the patient says she’s pregnant.
You do know of the concept that women can be pregnant without them realizing or without them acknowledging it?
It’s like asking someone whether they have worms. They might know, but they might also not know. They might even know and not tell you.
All of that can be circumvented with a different question.
So you can choose to be offended by a question that they are actually legally required to ask, or you can understand that the main purpose of a doctor (or other medical personell) is not polite dinner conversation but actually assessing the situation to give appropriate treatment.
I only had one instructor out of my maybe 10 or so said to check to make sure the patient can physically get pregnant before you assume that is the issues
I know at least one woman who physically couldn’t get pregnant until she got pregnant.
She hat ovary cancer and they removed one and a half ovaries. It was determined that the remaining ovary was too damaged to still produce any eggs. She had eggs frozen before the operation, and she and her husband used all of them up in IVF, none worked.
They then gave up and adopted a kid, and a few years later a second one. Right after they adopted the second one as a newborn, she got pregnant. Apparently, they stopped using contraception because couldn’t get pregnant anyway. Now they have two kids under the age of 1.
She totally would have told any medical professional that she physically couldn’t get pregnant, until she did.
I think there is the misconception that patients have, that they expect doctors and other medical staff to be polite.
They are not there to be polite, they are there to fix a problem.
In regular situations it’s wildly impolite to ask a woman whether she’s pregnant, especially if she’s not. But a doctor needs that information, so it would be quite smart if people would just get over themselves and understand that they will be asked a few impolite questions when talking to medical staff.
Reminds me of the one time one of our sales people video called me with an urgent bug report that his demo unit wasn’t responding via SSH or HTTP and that it’s probably broken because of our last update and whatnot.
I asked him if he checked the power and network cables. He gets angry and tells me that of course the cables are ok.
So I ask him if it’s the unit I can see on the shelf behind him. He says yes. I say, “All the LEDs on the front of the unit are off. Are you sure the power cable is plugged in?”. It wasn’t.
This is the doctor equivalent of that video call.
Not every time it’s the simple answer. But sometimes it is, so you ask the simple question every time.
To be fair: It does make sense. A pregnancy test is rather cheap and simple to do. Abdominal CTs are linked to an elevated risk of cancer for an unborn child.
So to put it differently: If you could heal a child from their cancer by taking a blood test, wouldn’t you?
If the fetus dies, that’s one thing. If the fetus gets deformed due to medication, that’s another thing and the one suffering from that is not the woman, hence it’s not only her business.
To put it differently: If you could heal a severely disabled child by peeing in to a cup, would you not do it?
Don’t you know that doppelgangers have really weird periods? That’s the question medical professionals are trained to ask to figure out if someone’s a doppelganger.
Works fine in any language I ever used.
I’m honestly quite surprised that this very basic language feature is even a matter of discussion here.
