Hey guys!!!

I am kinda new to python. For university I have an assignment to build a function plotter.
At the current state I have a configuration file with the parameters "f", which contains a string, example given "-x^2*sin(x)" and others like "start", "end", "step" of the plot.

Now I want to be able to plot the function with using matplotlib, so I will need a function, which translates the mathematical functions in the string to the plotable values or something similar.

I feel like I could lose a lot of time If I try this the wrong way.

Does anybody have some ideas or cool libaries, which can help with that?

According to the assignment, the program doesn't have to be able to detect every function,
but I guess the more the merrier.

For now I would build a big "if"-tree checking for every possible combination, but I feel like this could be easier.

Thanks a lot!!!

I don't know about the rest of ya'll, but the strike exclusive Flayer Mantles from D1 were one of my favorite mini grinds in that game, and I didn't even run my Hunter that much! Just destroying those little turd triplets for hours on end with my buddies was a great time because when someone got a mantle they didn't have we all freaked out. Or when someone got their third void mantle but didn't have the other two we laughed our asses off.

I would love to see more strike (or other activities) exclusive loot work the same way. Maybe in the Broodhold strike where Anânh's forms drop something? Or the two spider tanks from the heroic public event each have a chance at dropping a different weapon? The first could drop some weak-ass rocket launcher but the second drops an item you could use to upgrade it into what becomes a pseudo scorch cannon?

I guess what I'm trying to say is that more activity exclusive loot, especially with multiple variants or stages, would such a nice addition. I know we have a lot of things already, but trickling in more would always be welcome in my book...

Anyone know how to set the post flair in the Narwhal app?

I'm trying to work out a PDE using similarity / stream function and all of the algebra in setting it up is a bit of a headache with huge room for error.

I'm having to take the derivative of F with respect to x and y at various points, but I don't know a way to make MATLAB recognize that F = F(x/y) in a way that allows me to take the derivative (symbolically) with respect to n as well.

I've tried functionalDerivative but I'm not sure if it's not the right use-case or what, but I couldn't get it to work.

Hello,

I bought a bass for cheap and fixed most of the issues with it myself, but the part that is the only issue left is really hard to find.

This controls the bass and treble boost/cut and feeds into a 2 band EQ circuit that is just plugged in.

I'm wondering if I can take off the three wires leading into the potentiometer and solder them on into a stacked potentiometer so I wouldn't have to find a specific piece.

This is the part I can't find.

I was never given an option to choose, I just opened it one day last week and only my timeline was affected by the new (horrible) design.
There seems to be no option to switch back and don't get me wrong, I wouldn't be so mad about it, if it weren't for the unbelievably stupid glitches it brought in:
- I am NO LONGER able to "skip cropping" when I pick a new profile pic, the option itself has vanished, which makes for picking an incredibly ugly pixelated low quality fragment out of a whole picture
-The button to change my cover photo simply does NOT respond. I press on it but nothing happens.

So WHY, oh why does FB insist on making changes that don't even work properly, let alone look ugly and bulky?
I hate that tendency to bring tablet/mobile layout to desktop - nobody needs huge buttons!

Does anybody know of a way I can switch back to my old timeline layout?

Hey everyone, I'm looking for a mechanism that applies torque only in one diraction of rotation, something that resembles a torsion spring or a ratchat mechanism. Thanks for the help!

So, let's take my example (ESTP). I have Se as dominant, Ti as auxiliary, Fe as tertiary and Ni as inferior.

Se Ti Fe Ni.

So say you found a very efficient manager at a bank or someplace and you thought him to be an ESTJ. Eff, you only know the basic knowledge of functions and can't recall functions of a particular type with ease. But you do know that an ESTP has Se Ti Fe Ni. And if you were to switch the last letter (estP to estJ), the first pair of functions would switch places with each other. And so will the second pair. It'll become Te Si Ne Fi.

Now let's assume at college, you found a person marshalling people for conga (an ESFP). If you were to switch the third letter (esTp to esFp), the second function will become the third. (with a shift in direction). It'll become Se Fi Te Ni.

>Note that the shift in direction means if a function is introverted, it becomes extroverted.

Oh, don't even forget the best debater you met during a debate competition in your school (an ENTP). If you were to switch the second letter (eStp to eNtp), the first function will become the fourth (with a shift in direction). It'll become Ne Ti Fe Si.

And that mechanic who fixed your car so well (an ISTP). If you were to switch the first letter (Estp to Istp), the first function will become the second, the third function will become the fourth (with NO shift in direction). It'll become Ti Se Ni Fe.

Oh, and if a type is the COMPLETE opposite (ESTP's opposite is INFJ), the functions would be exactly the same, but the order will be completely opposite.

In short:

>XXXP to XXXJ or vice versa: 1st function will become 2nd, 3rd function will become 4th. (with a shift in direction)
>
>XXTP to XXFP or vice versa: 2nd function will become 3rd. (with a shift in direction)
>
>XSXX to XNXX or vice versa: 1st function will become 4th. (with a shift in direction)
>
>EXXX to IXXX or vice versa: 1st function will become 2nd, 3rd function will become 4th. (with NO shift in direction)
>
>Going from one type to its polar opposite: Functions would remain the same; the order will become the opposite.

Another example: Take INTJ. Functions are Ni Te Fi Se.

INTP functions would be Ti Ne Si Fe. The J changed to P. So quoting the above rule:

>XXXP to XXXJ or vice versa: 1st function will become 2nd, 3rd function will become 4th. (with a shift in direction)

You see, Ni became Ne, Te became Ti, Fi became

have lyme disease and have been sick for a really long time. i had to quit my job two years ago and am struggling to finish college (should have graduated last spring but im so far behind, my brain doesnt work right, hard to explain). my parents are on my case about finishing college and constantly tell me that “i’m better now” when that isnt the case at all. i had little spurts of feeling “ok” over the summer but i think i became resistant to the medication, now im falling back down and i’m tired of it. right now my source of income is music its the one thing i can still somewhat do but its really inconsistent in terms of when i get paid. i tried going out with my friends the other night but i can’t drink cuz of all the pills im on so i kinda just stood around, i don’t even know how to interact with people anymore because of how much time i spend locked away in my room. i’m a fucking mess and i feel like the walls are closing around me and every step forward i make becomes two steps back. i don’t recognize myself anymore, i’m barely eating, showering, sleeping. i’m so fucking depressed i’m tired of feeling like this. normally i’m the type to lend a hand to others but i can’t even help MYSELF anymore. all i think about is jumping off a bridge or downing a whole container of my pills nd call this shit quits. i’m tired of being sick, tired of burdening everyone around me, tired of missing my old life, i want out of this one NOW.

TL;DR very sick and getting sicker, need an efficient way out

Terrible at making two roads run parallel.. yes I know there is the parallel road mod but was hoping to find one road that acted like a two way highway.

Thanks

this is the popular rule to prove that a function is injective but sometimes it's complicated to prove so is there another one ?

Hi,

I am building a ETL application that takes data from a 3rd party app, upon submission in that app a webhook fires off JSON data.

My current structure is:

1. data from 3rd party app fires off via webhook
2. Zapier catches that
3. Zapier parses the SAME data into 3, s3 buckets
4. 3 Lambda functions using 3, s3 buckets with the same data do different operations. Lamda operations reading files.

What is best way to having the 3 lambda functions read the data from the same source?

I saw this article https://docs.aws.amazon.com/sns/latest/dg/welcome.html But not sure how aws sns would store the JSON file?

Just looking for a function to meet these requirements

if a1=true and b1 is NOT "hello"

thanks!

Basically, have a custom VPC with 3 private subnets.

created a dbsubnet group with the private subnets.

configured RDS to use the dbsubnet group.

security group of rds database is say sg_db.

private ip address of ec2 instance is say private_ip_1

security group of ec2 instance is sg_app_server_1

two ways to restrict access from ec2 box are,

adding inbound access in sg_db to port 3306, from private_ip_1

adding inbound access in sg_db to port 3306, from sg_app_server_1

And since Lambda function by default does not launch within a VPC, I have configured it to use the VPC and the private subnets to launch, and then associated with a security group sg_lambda_1

and then I have added the inbound rule in sg_db to allow access to port 3306 from sg_lambda_1.

Is there a more secure way of doing this, or am I right here.

additionally, say I don't want the Lambda to launch in VPC, so the start times of the lambda would be less. in that case, how do we allows the access to the private rds db from a public lambda function.

And is there a way to do this using IAM policies? and not security groups.

var Type1 = function() {
    return 'Type 1';
};

function Type2() {
    return 'Type 2';
}

console.log(Type1());
console.log(Type2());

One is stored in a variable so maybe it's easier to work with or something?

Thank you!

I'm very frequently using a formula that looks like CONCATENATE(VLOOKUP(..), "-", VLOOKUP(...))

Instead of using that everywhere, because there's only one argument I just want to call MYLOOKUP(..) which will call the above formula.

How can I do that?

Doesn’t even OHK in cruci, derp.
