QUESTION
I'm fairly new to Tableau, but otherwise pretty well versed in data and SQL, etc.
I'm working on a dashboard that will display some financial data. The two main categories are "Actual" results and "Plan" (or budget).
The Actual results are at the individual transaction level by cost center and by account. The Plan is at the cost center and account level. For example:
Actual table:
...ANSWER
Answered 2020-Apr-15 at 19:20When joining it will be put against the transaction level, as with any normal inner join. Therefore you have options on how to handle this.
You could do it using an aggregation - i.e. instead of SUM you could MIN / MAX / AVG the field, which would always return the same value.
Alternatively you could blend this data, rather than join. If you blend in the visualisation layer and only blend it when showing the Cost Centre level, this will prevent aggregating against all transactions. To blend this would be a completely separate data source. It would "blend join" in Tableau - see Data - Edit Blend Relationships in Tableau.

Answered 2020-Mar-07 at 12:10You are calling incorrectly. You call it as https://www.sitename.com/Projectmanagerinterviewtips.php
but your controller name should be in small letters and without extension ".php" like this.

QUESTION
I've asked this on math overflow and used comments to clarify/overstate my question. I hope it has the intended effect and doesn't come off as jarring.
I'm attempting to find what subset of numbers reach a known average.
I have a list of known values, negative and possible decimals. They look something like this {-.32,-.64,-.12,.08,-.54,-.43, ...}
It's around 50 numbers in some cases, though this problem would be tested for other cases as well.
The set mostly contains negative decimal numbers, while in rare cases, has a few positive decimals - it never has whole numbers.
I also have a known value, which I know to be the average of some subset of the above list.
The known value is similar to -.03.
I'm uncertain of the grouping mechanism used, but seemed to reach stack overflow trying to solve this problem when not grouping.
I've attempted a few ways of going about solving this problem. I'm using Python 3.6 and imported numpy as np.
I'm wondering if the "subset-avg" code I've adapted from another solution for subset-sum here (I'll give due credit when i can find that question again) is not the most efficient way/if there's any huge mistake in my even attempting to resolve this that I haven't seen.
Thanks in advance for any thoughts.
...ANSWER
Answered 2019-Jul-25 at 12:45Here is a solution I adapted from a subSet sum algorithm I posted for another question (here). Since the algorithm loops through potential solution sizes, it was easy to adapt it to search for an average.
The iSubSum()
function takes 3 parameters: The target average, the list of values and an optional rounding precision parameter. It is a generator so it will produce all possible solutions when used in a loop. You can also get the first solution quickly using the next()
function. This should produce results much faster than a brute force approach, especially for large lists.
The function is based on a modified version of a subset-sum algorithm that returns solutions as lists of indices. This is intended to distinguish combinations that have duplicate values coming from different indices in the original list.
QUESTION
So I wrote a program to print songs like an old dot matrix printer, character by character. When I run the thing in Idle it does it and works fine, but when I call the program from the Linux Terminal the text is printed line by line, instead of character by character, and it really takes away from the whole effect and point of the program. Is there anything I can do to fix this or is it just how the Terminal will work with it. Thanks

QUESTION
I have a single paged PDF that looks like this that is 6.3 MB. Because it seems to already be in greyscale in the first place, applying a greyscale should not make a huge difference.
But when I apply a greyscale to the PDF with:
...ANSWER
Answered 2018-Aug-21 at 10:40Supplying PNG images, rather than the actual PDF files, makes it impossible for anyone to be able to tell for certain what your problem is. If you had posted the PDF files I'd be able to look and tell you.
However, I'm going to guess that you are using an older version of Ghostscript (again you don't say), and that the image in the original file is DCT (JPEG) compressed.
Because you haven't specified a particular compression method, the pdfwrite device (not Ghostscript, but the Ghostscript device which writes PDF files) uses 'Automatic' compression. It writes the image data multiple times with different compression filters, and selects the one which produces the smallest output.
Almost certainly this will again be the DCT (JPEG) compression filter, it almost invariably produces the smallest output. This is also the default filter which is used if you disable automatic selection and don't specify a different compression filter to use.
The problem is that DCT is a lossy compression, so every time you decompress and recompress it, you lose fidelity. Though the image size in bytes does decrease each time.
So that's the reason for both your results; the compression artefacts and at least part of the reduction in size. It may also be the case that your original Grayscale image is actually not Gray but RGB (or Lab or CalRGB, or ICCBased...), in which case converting it to grayscale will result in a decrease in size of 66%. Without seeing the file I can't tell.
Note that current versions of Ghostscript use a JPEG passthrough feature. Provided that the image is not being downsampled, or having its colour space altered, the image is not decompressed. It is passed unchanged to the output device, which embeds it unchanged. This avoids the artefacts introduced by decompression and recompression.
Obviously if you want to change the colour space, then the pdfwrite device does have to manipulate the image, so it has to decompress it.
You can select the compression filter you want to use, instead of permitting automatic selection, by using the GrayImageFilter distiller parameter see here.

For school I am to write a C program that takes some amount of cash and returns the smallest number of coins it would take to reach that amount. I don't know what I am doing wrong. I've been tweaking and trying all sorts of different things but I cannot seem to totally debug the program.
The program gives correct answers to some inputs but overstates the amount of coins needed for many inputs.
Here is what I have so far.

QUESTION
I am not sure whether my solution is justifiable (ans. 171) - Project Euler Q.19 since I am having a hard time getting my head around modular arithmetic and not really sure whether my approach to it was correct or not... I was having trouble on trying to get the equivalence of having 0 as a key rather than 1 to Monday for reference in a hash table. The question was;
- 1 Jan 1900 was a Monday.
- Thirty days has September, April, June and November. All the rest have thirty-one, Saving February alone, which has twenty-eight, rain
or shine. And on leap years, twenty-nine.- A leap year occurs on any year evenly divisible by 4, but not on a century unless it is divisible by 400.
How many Sundays fell on the first of the month during the twentieth century (1 Jan 1901 to 31 Dec 2000)?
So what I did was start the sum of days at 1 (reference for days in hash table) and subtract 1 after finding the sum of Sunday's, since doing it by 0 caused problems when the total sum of days were divisible by 3 and 6 (3:Wednesday, 6:Sunday). How could I have done this by using 0 as reference for Monday?
