Test for a cell not being fumulaically populated vs one with data sourced from a dfiferent cell : I have a spreadsheet that auto-populates column B to equal the cells in column A. Column C will be the cell in column A, one row down, but if the cell in column A of the same row and column A of the next row are the same, it wil be column A of two rows down. Using this formula: =IF(A5=A6,A7,A6).
Right now, it prints data in one of the cells when they only contain the formula. I dont understand why.The right column below, which has 2 indigo,
is an example of the problem, with 'empty' where the cells are not populated, they have a blank pick list.
red red orange
orange orange yellow
yellow yellow green
green green blue
blue blue 0
empty 0 indigo
empty 0 indigo
indigo indigo violet
----------------------------
I don't mind the 0 being displayed, but the 3rd column up, right cell, is printing indigo, when it shouldn't be. The columns above that work fine.
NOTE: The cell in column C, violet, has a slightly different formula, if the
first cell matches the cell below, it sets it to the first data cell in column c, otherwise to the next cell in column A =if(a8=a9,a2,a9)
What I need to see to reduce the risk of human error, is have either a zero, or
nothing displayed in the cell which is showing the first indigo in column c. | 0debug |

File download progress in the browser: Angular 4 : <p>I'm creating an application that consumes a REST api for downloading a file. The api returns the file right when you hit it. So I'm using the following logic to get the file:</p>
<pre><code>downloadFile(file) {
this.service.downloadFile(file.id).subscribe((fileData) => {
const a = document.createElement('a');
document.body.appendChild(a);
const blob = new Blob([data], { type: data.type });
const url = window.URL.createObjectURL(blob);
a.href = url;
a.download = file.name;
a.click();
window.URL.revokeObjectURL(url);
});
</code></pre>
<p>}</p>
<p>The above code works perfectly. BUT, it downloads the file in the browser when the whole file is downloaded, i.e., you wont see the progress of file download in the browser (how we usually see when we download a file usually in Chrome). You can see its downloading the file in the 'network' tab of the console, but only shows up when the whole file is downloaded.
Can anybody give any idea how can I force it to download in the browser so that it shows the progress?</p>

(Newbie) invoking child nodes entity framework core : I`m new into this sort of Object programming, do you mind helping me?
I have to invoke the child nodes, but specific fields, but I can`t figure out how, I`ve already looked into a huge amount of places, but it doesn`t seem to work.
For exmaple, I want just the FirstName in the RepunicAccount, and all the other info from REpunicAccountType, or anything like it.
My DbContext
using System;
using System.Collections.Generic;
using Microsoft.EntityFrameworkCore;
using Microsoft.EntityFrameworkCore.Design;
using Models.Account;
namespace Models.dbContext {
public class RepunicContext : DbContext {
public virtual DbSet<RepunicAccount> RepunicAccount { get; set; }
public virtual DbSet<RepunicAccountType> RepunicAccountType { get; set; }
protected override void OnConfiguring (DbContextOptionsBuilder optionsBuilder) {
optionsBuilder.UseSqlServer ("Integrated Security=SSPI;Persist Security Info=False;Initial Catalog=Repunic;Data Source=DESKTOP- 6I8LD45\\SQLEXPRESS_ERICH");
}
public RepunicContext (DbContextOptions<RepunicContext> options) :base (options) { }
public RepunicContext () { }
}
}
My Model
using System;
using System.Collections.Generic;
using System.ComponentModel.DataAnnotations;
using System.ComponentModel.DataAnnotations.Schema;
namespace Models.Account {
public class RepunicAccount {
public int ID { get; set; }
public string Email { get; set; }
public string Username { get; set; }
public string Password { get; set; }
public string FirstName { get; set; }
public string LastName { get; set; }
[ForeignKey ("ID_Type")]
public int? ID_Type { get; set; }
public ICollection<RepunicAccountType> TipoConta { get; set; }
public DateTime? DataCadastro { get; set; } = DateTime.Now;
public DateTime? DataAlteracao { get; set; } = DateTime.Now;
}
}
My Child Node
public class RepunicAccountType {
[Key]
public int ID_Type { get; set; }
public string Descricao { get; set; }
public DateTime DataCadastro { get; set; } = DateTime.Now;
public DateTime DataAlteracao { get; set; } = DateTime.Now;
}
I Have a repository, that is where I do my coding, before putting into the controller, it`s pretty much the same in every place, but I`m going to send the example that I`m trying to use in both places.
public IEnumerable<RepunicAccount> GetAllByIDType () {
var data = db.RepunicAccount.Where (a => a.ID_Type != null).Include (p => p.types);
var type = db.RepunicAccountType.OrderBy (b => b.Descricao);
return data.ToList ();
}
The problem is, I don`t know how to invoke specific itens nor make anything else than ToList();
So, What should I do? If there is any more info that I can send, just ask me.

How to run a jquery function in Angular 2 after every component finish loading : <p>I have tried all the life cycle hooks but can't get to accomplish the needed result.
The result that I need is triggering a function that initialize many jquery plugins used for different elements on a single page after every single one of these elements (components) is loaded.</p>
<p>So lets say that you have this structure.</p>
<p>Home Page
Slider
Widgets
Product rotators
..etc</p>
<p>Every one of these elements has it's own component and all are children of the Home page parent component.</p>
<p>And what I need here is to know when all the children components and the parent component is loaded so I trigger one jquery function to initialize every plugin on the page. </p>

How to go to the other round of two loop at the same time? : How to go to the other round of two loop at the same time?
code :

for i_parameters = 1: numel(parameters)
my_parameters = parameters{i_parameters};

my_time = Time{i_Time};
for j = 1 : 7
Difference.(my_parameters).(my_time) = [Diff.(my_parameters)(:,j); Diff.(my_parameters)(:,j+7); Diff.(my_parameters)(:,j+14); Diff.(my_parameters)(:,j+21); Diff.(my_parameters)(:,j+28)];

I would like to leave the loops `i` and` i_Time` at each turn and at the same time that I would like to apply: `i_Time = T0 then j = 1 / i_Time = T1 then j = 2 / i_Time = T2 then j = 3 / i_Time = T3 then j = 4 / i_Time = T4 then j = 5 / i_Time = T5 then j = 6 / i_Time = T6 then j = 7`

String backward another way : <p>I am very new to Python and I encountered one issue that I cannot understand. Let say I have string variable:</p>
<pre><code>myVar = "abcdefgh"
</code></pre>
<p>I want to display it backward, no problem: </p>
<pre><code>print(myVar[::-1])
</code></pre>
<p>and I get hgfedcba. Nothing surprising here. I should get the same with this somewhat verbose code:</p>
<pre><code>print(myVar[len(myVar)-1:0:-1])
</code></pre>
<p>but this time the result is hgfedcb. Then I have tried not to subtract 1 from len(myVar) and the result was exactly the same. I do not understand why, especially that lines:</p>
<pre><code>print(myVar[::1])
print(myVar[0:len(myVar):1])
</code></pre>
<p>display the same results. </p>
<p>So, my question is why print(myVar[len(myVar):0:-1]) does not display "a"?</p>

VBA append some columns to another column and also create a seperate column to contain the appended columns title headers : I am working on a research portal for a client, they have their data in an excel workbook and each sheet containing stock prices for a particular year. There are about 11 worksheets (each representing a year i.e sheet 2008 - 2019). To keep things simple, each sheet has a column for Company Symbol Ticker, then other series of columns each representing a trading day. So it looks like (Symbol Ticker, 04 Jan 2008, 05 Jan 2008,06 Jan 2008,..,31 Dec 2008). I want to store this data in a database but dont want to have that huge freaking number of columns in the database one major reason being that the trading days is not the same for all sheets(years).
So how i want to store this data is have a date column in the database, values column , and the company's column , so basically (date,value,companyID).
I have transposed the table and placed the companies IDs (1,2,3,...) on each corresponding value columns to identify the company that has values in a particular column.
The next step now is to arrange these data in a 3 column (date,value,companyID) so that i can convert to CSV and import into the database. I know an excel macro can handle this very sure but cant figure out how to go about it as i am still a beginner in VBA. Thanks for your help in advance.

Basic addition in notepad++/python : I am using notepad++ to write code for python and have a variable that I need to add 1 to for my next question. I am new to coding and would like to know how to achieve this. I would also like to phrase the question so that the answer (variable plus 1) is placed between text. Below, in my next line I would like it to read (for instance if the number is 3) How often do the 4 of you visit?
I have tried different ways of framing my variable +1 within parentheses and quotation marks but at best, when run, it shows exactly what I wrote not the answer to the equation.
famnumber = input ("How many of your family members still live there?")
I would like the answer to appear within text as noted above if possible.

<ul>
<li>dashboard</li>
<li>csvtimeline</li>
<li>csvjson</li>
</ul>
<p>Now i have by default set redirectTo to my dashboard component. but in place of this redirect i want to redirect to csvjson component or csvtimeline component based on login user profile.</p>
<p>Suppose</p>
<p><strong>If Login User is "Admin" he should be redirectTo - > dashboard Component</strong></p>
<p><strong>If Login User is "Guest" then he should be redirectTo - > csvjson component</strong> </p>
<p>i know we can do this in ngOnInit() of dashboard component for redirect.</p>
<pre><code>if (this.user && this.user.profile.role == 'Guest') {
this._router.navigate(['csvtemplate/csvjson']);
}
</code></pre>
<p>but i am looking for better option so i don't have to open dashboard component each time and it will directly go to csvjson component.</p>

vba quarterly retuns : Can anybody tell me a VBA Function or button that would calculate quarterly returns only on a quarterly basis (i.e., first quarter return is based on January till March returns) without overlapping observations. The function that I'm using now is just the AVERAGE of, for example, returns from January until March, but the actual calculation cell is in April. An example of what I'm asking is in the picture link. I would like the function to run for the time period that I choose.

NxN Matrix of random numbers using nested for loop : <p>I skipped a semester and completely forgot the basics of coding and my new professor at my new campus is jumping right into coding problems instead of reviewing like i figured he would do. I am to write a program that creates a 4x4 matrix of random integer values from 0-9, and then reduces it to a 2x2 matrix of doubles by averaging the 4 quadrants. I vaguely remember how to do a random number generator but the matrix alludes me. If someone would be willing to help me and walk through it with me i would much appreciate it!</p>
<p>An example of what it is suppose to look like would be something along the lines of this.</p>

Preventing compiler optimizations while benchmarking : <p>I recently came across this brilliant cpp2015 talk <a href="https://www.youtube.com/watch?v=nXaxk27zwlk" rel="noreferrer">CppCon 2015: Chandler Carruth "Tuning C++: Benchmarks, and CPUs, and Compilers! Oh My!"</a></p>
<p>One of the techniques mentioned to prevent the compiler from optimizing code is using the below functions. </p>
<pre><code>static void escape(void *p) {
asm volatile("" : : "g"(p) : "memory");
}
static void clobber() {
asm volatile("" : : : "memory");
}
void benchmark()
{
vector<int> v;
v.reserve(1);
escape(v.data());
v.push_back(10);
clobber()
}
</code></pre>
<p>I'm trying to understand this. Questions as follows.</p>
<p>1) What is the advantage of an escape over clobber ?</p>
<p>2) From the example above it looks like clobber() prevents the previous statement ( push_back ) to be optimized way. If that's the case why the below snippet is not correct ?</p>
<pre><code> void benchmark()
{
vector<int> v;
v.reserve(1);
v.push_back(10);
clobber()
}
</code></pre>
<p>If this wasn't confusing enough, folly ( FB's threading lib ) has an even <a href="https://github.com/facebook/folly/blob/master/folly/Benchmark.h" rel="noreferrer">stranger implementation</a> </p>
<p>Relevant snippet:</p>
<pre><code>template <class T>
void doNotOptimizeAway(T&& datum) {
asm volatile("" : "+r" (datum));
}
</code></pre>
<p>My understanding is that the above snippet informs the compiler that the assembly block will writes to datum. But if the compiler finds there is no consumer of this datum it can still optimize out the entity producing datum right ?</p>
<p>I assume this is not common knowledge and any help is appreciated !</p>

How to use MongoDB with promises in Node.js? : <p>I've been trying to discover how to use MongoDB with Node.js and in the docs it seems the suggested way is to use callbacks. Now, I know that it is just a matter of preference, but I really prefer using promises.</p>
<p>The problem is that I didn't find how to use them with MongoDB. Indeed, I've tried the following:</p>
<pre><code>var MongoClient = require('mongodb').MongoClient;
var url = 'mongodb://localhost:27017/example';
MongoClient.connect(url).then(function (err, db) {
console.log(db);
});
</code></pre>
<p>And the result is <code>undefined</code>. In that case it seems this is not the way to do so.</p>
<p>Is there any way to use mongo db inside Node with promises instead of callbacks?</p>

I know html tag has a class property, but class property does not have a key called "selected". The class property may have a value, which is string "selected". How come this property binding is valid? </p>
<p><strong>Question 2:</strong>
How does above property binding translated to class="selected" ?</p>

Is there a way to Parse String to DateTime, when the string comes with different formats : <p>I am working on building a console application which read a .csv file and add the values to the database. now i have some CSV columns which store date time values.
But those column sometimes contain the datatime with seconds while sometimes it does not. here is a sample of some data for the date field:-</p>
<pre><code>03/30/2016 10:55:49
04/01/2016 11:02
</code></pre>
<p>now when i try to parse the above string into a date-time as follow:-</p>
<pre><code>formattedDateCreated = DateTime.ParseExact(fields[DateCreatedIndex], "MM/dd/yyyy HH:mm:ss", CultureInfo.InvariantCulture);
</code></pre>
<p>i will get the following exception when i try to parse the second date :-</p>
<pre><code>String was not recognized as a valid DateTime
</code></pre>
<p>so can anyone advice on this please? how i can make my Parse more dynamic to work on date formats with seconds or without seconds??
Thanks</p>

In ES6, export let m = 1; and m =1 expoort m ; why the former is true, the latter is false? : ```
export let m = 1;
```
```
let m =1;
expoort m;
```
I know the export of ES6 Module need to be an interface. The former export an interface,and the latter export number 1.
I want to know why the former export an interface? I guess priority of operations, but I am not sure.

Simple java calculator always outputs 0 : <p>I am new to java, i am trying to make a little calculator that takes the input of two numbers and an operator. This data is then taken into an if statement to calculate the answer. Then output into the console. I am having a problem though because with the:</p>
<p>operator = Calc.next();</p>
<p>Because i thought that the above line of code was correct for inputting a string but it doesn't work, whatever the numbers input to the calculator are, the answer seems to be output as zero.</p>
<p>Please take the code from the pastebin link and look at it because i'm not sure what is going wrong. I would appreciate someone letting me know where i went wrong. </p>

Python logger per function or per module : <p>I am trying to start using logging in python and have read several blogs. One issue that is causing confusion for me is whether to create the logger per function or per module. In this <a href="https://fangpenlin.com/posts/2012/08/26/good-logging-practice-in-python/" rel="noreferrer">Blog: Good logging practice in Python</a> it is recommended to get a logger per function. For example:</p>
<pre><code>import logging
def foo():
logger = logging.getLogger(__name__)
logger.info('Hi, foo')
class Bar(object):
def __init__(self, logger=None):
self.logger = logger or logging.getLogger(__name__)
def bar(self):
self.logger.info('Hi, bar')
</code></pre>
<p>The reasoning given is that </p>
<blockquote>
<p>The logging.fileConfig and logging.dictConfig disables existing loggers by default. So, those setting in file will not be applied to your logger. It’s better to get the logger when you need it. It’s cheap to create or get a logger.</p>
</blockquote>
<p>The recommended way I read everywhere else is like as shown below. The blog states that this approach <code>"looks harmless, but actually, there is a pitfall"</code>.</p>
<pre><code>import logging
logger = logging.getLogger(__name__)
def foo():
logger.info('Hi, foo')
class Bar(object):
def bar(self):
logger.info('Hi, bar')
</code></pre>
<p>I find the former approach to be tedious as I would have to remember to get the logger in each function. Additionally getting the logger in each function is surely more expensive than once per module. Is the author of the blog advocating a non-issue? Would following logging best practices avoid this issue?</p>

Spring JPA Lock : <p>I am really insecure when it comes to locking in spring jpa.<br>
So please consider this question as an clarification. I really hope I understood it correct, but my english is not so good for understanding complex blog posts.<br>
So this is what I think I got from some articles: </p>
<p>There are two basic types of locking: </p>
<ul>
<li><strong>optimistic</strong> should be used when less write operation are planned. read operation will not lock an object.<br>
For example: You have an "money balance" float in an entity with an optimistic lock. Now two processes read this value and use it for calculating and stuff. One of them now changes the value and writes it to the database with an update. No error to this point.<br>
But now the other process also changes the value and wants to update it. Now there is an error. This only happened because of the second update.<br>
If the second process would have deleted the instance, nothing would have happend. </li>
<li><strong>pessimistic</strong> should be used when much write operation are planned. read operation will lock an object.<br>
For example: You have an "money balance" float in an entity with an pessimistic lock. One process reads the data/value with "findOne".<br>
After this, an other process wants to read the data as well, what would be possible with an optimistic lock, but with the pessimistic lock he must now wait (no error, just wait).<br>
When process 1 is ready (changing the value and updating it), process 2 can go on. </li>
</ul>
<p>First Questions: Is this correct so far? And when I now want to test this knollage, I can choose between this LockModeType's: </p>
<ul>
<li>OPTIMISTIC </li>
<li>OPTIMISTIC_FORCE_INCREMENT </li>
<li>PESSIMISTIC_READ </li>
<li>PESSIMISTIC_WRITE </li>
<li>PESSIMISTIC_FORCE_INCREMENT </li>
</ul>
<p>Why are there now so many sub-locks and what do they do? When "OPTIMISTIC" is the optimistic lock from the top I tried to understand, then what is "OPTIMISTIC_FORCE_INCEMENT"?<br>
And what does an version update has to do with this? (or the <code>@version</code>?) </p>
<p>Going on:<br>
There are three basic uses of lock in Spring jpa: </p>
<ol>
<li><p>on a normal column, for example: </p>
<pre><code>@Entity
public class PersonEntity {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Long id;
@Lock(LockModeType.PESSIMISTIC_WRITE)
private String name;
}
</code></pre></li>
<li><p>on a foreign key to an other table, for example: </p>
<pre><code>@Entity
public class PersonEntity {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Long id;
@Lock(LockModeType.PESSIMISTIC_WRITE)
@OneToOne
private Group group;
}
</code></pre></li>
<li><p>on a table inside a repository, for example: </p>
<pre><code>interface PersonRepository extends Repository<Person, Long> {
@Lock(LockModeType.PESSIMISTIC_WRITE)
Person findOne(Long id);
}
</code></pre></li>
</ol>
<p>Locking a Entity directly with </p>
<pre><code>@Entity
@Lock(LockModeType.PESSIMISTIC_WRITE)
public class PersonEntity { }
</code></pre>
<p>is not possible. Therefore you can use 3 (locking inside a repository). </p>
<p>Second Question: Is this correct? Did I forgot about a use of a locking? </p>
<p>Going on:<br>
The idea behind locking is, that other methods/processes have to wait until a lock is released (except by the optimistic lock, here a error is thrown).<br>
The Lock is there as long as the instance/object is active or until the next commit.<br>
There are two main possibilities to unlock an object: </p>
<ol>
<li><p>Within an transaction: In this full method the lock is active. But when the return comes, the lock will be removed. </p>
<pre><code>@Transactional
public void test(){
System.out.println("start, but not locked yet");
PersonEntity person1 = personRepository.findOne(1L); // locks this person or must wait, when locked
System.out.println("now locked");
// do something
return true; // now the lock will be deleted -> unlocked again
}
</code></pre></li>
<li><p>until the object is deleted: The data will be locked when the object is selected, and the data will be unlocked when the object is deleted. </p>
<pre><code>public void test(){
System.out.println("start, but not locked yet");
PersonEntity person1 = personRepository.findOne(1L); // locks this person or must wait, when locked
System.out.println("now locked");
// do something
person1 = null; // now the lock will be deleted -> unlocked again
System.out.println("not locked anymore");
// do something more
return true;
}
</code></pre></li>
</ol>
<p>Third Questions: is this correct so far? Does this function really can wait then the data is locked? Can an lock really be deleted when the object is set to <code>null</code>? </p>
<p>Last words:<br>
I really hope I will not annoy somebody. But like I said: it is really difficult for me to understand such complex structures in the english language :(<br>
So thanks a lot for help in any form :) I really appreciate any little help. regardless of whether you give me links for more understanding or answering my questions directly :)</p>

c++ Basic If_else Statements : I am a beginner of c++
This is the line of code I have written using if,else statements
#include <iostream>
#include <stdio.h>
using namespace std;
int main() {
int a =5;
if(a)
{
printf("if %d\n" , ++a);
}
else
printf("else %d\n" , a);
}
what happens is if I take int a =5 it prints the value "if 6"
and if I Take int a =0 it prints the value "else 0"
Why is it happening what is the reason?

What is the best bitmap size to insert into android studo? : <p>I have a couple images that I am adding to android studio, however, I will the error that, the bitmap is to large. Additionally, larger bitmaps will increase my heap amount and create my app to run slower, therefore, I am asking what the ideal image size to upload is for a reasonable sized bitmap?</p>

How to ignore dependenies of a specific package with a pipenv : <p>Is there any possibility to install a python package without dependencies with <code>pipenv</code> package manager?
I'm looking for an analogue of <code>pip install package_name --no-dependencies</code> for the <code>Pipfile</code>.
I already tried to specify with a marker but it raises an exception. </p>
<pre><code>[packages]
"psycopg2-binary" = "*"
"aiopg"={version = "*", markers="--no-dependencies"}
</code></pre>
