data structures – Algorithm for Estimating Number of Unique Monthly Visitors

Is there a way to estimate the number of unique monthly visitors to a site based on a sample of, say, one week of data? This isn’t as simple as just multiplying the number of unique visitors the first week by 4, due to the hotel problem. If 10 people visit your site the first week and the same people are the only visitors to your site the second, third, and fourth week, the total number of monthly unique visitors to your site is only 10.

I know you can use HLL to estimate the number of unique visitors to a site in O(1) space. I’m wondering if there’s a similar approach to estimate how many unique visitors there will be after a month.

sql server – How to add values monthly between two Datetimepickers in VB.Net

I hope everyone has a good day.
I have a code which I add and update values in sql with vb.net, Here is the code :

       Dim db As ADODB.Connection
       Dim connstr As String
       Dim adoRS As ADODB.Recordset
       Dim sqlstr As String 

       db = New ADODB.Connection
       db.ConnectionTimeout = 10
       connstr = "Provider = sqloledb;Data Source=####SQLEXPRESS;Initial Catalog=####;Trusted_Connection=yes;"
       db.ConnectionString = connstr
       db.Open()
       sqlstr = "Select * from Expenses where ID = '" & Val(TxtID.Text) & "'"
       adoRS = New ADODB.Recordset
       adoRS.Open(sqlstr, db, ADODB.CursorTypeEnum.adOpenStatic, ADODB.LockTypeEnum.adLockOptimistic)

       If (adoRS.EOF = True) Then
           ' insert
           adoRS.AddNew()

           adoRS.Fields("Date").Value = DateTimePicker1.Value
           adoRS.Fields("Department").Value = TxtGrocery.Text
           adoRS.Fields("Description").Value = TxtItemDesc.Text
           adoRS.Fields("Payment").Value = TxtPayment.Text
           adoRS.Fields("Price").Value = txtPrice.Text
           adoRS.Fields("Quantity").Value = TxtQuantity.Text
           adoRS.Fields("Store").Value = txtStore.Text
           adoRS.Fields("MwSt").Value = txtMwST.Text
           MsgBox("Your Record has been inserted")
           adoRS.Update()

       Else
           If (MsgBox("This item in this date is already inserted " & vbCrLf & "Would you like to overwrite it?", MsgBoxStyle.YesNo, "This Item exist") = vbYes) Then
               ' overwrite
               adoRS.Fields("Date").Value = DateTimePicker1.Value
               adoRS.Fields("Department").Value = TxtGrocery.Text
               adoRS.Fields("Description").Value = TxtItemDesc.Text
               adoRS.Fields("Payment").Value = TxtPayment.Text
               adoRS.Fields("Price").Value = txtPrice.Text
               adoRS.Fields("Quantity").Value = TxtQuantity.Text
               adoRS.Fields("Store").Value = txtStore.Text
               adoRS.Fields("MwSt").Value = txtMwST.Text

               MsgBox("Your data has been overwrited")
               adoRS.Update()
           End If
       End If
       adoRS.Close()
       db.Close()  

What I want to do is set values each month between two datetimepickers. For example to insert the a mortage of the house for 5 years, from datetimepicker1 from 01.01.2015 to datetimepicker2 01.01.2021.

I googled a lot but there is no examples like this.

Your Help is much appreciated.

❓ASK – How much monthly do you earn from HYIP? | NewProxyLists

Good evening all!

At the title suggests, can you say how much money you make per month from HYIP? If you have that goal set up, personally I’d like to reach 200-300$ monthly, but sadly atm I make around 150-100$ or so. Kinda curious what are the deposit amounts for other people? Myself I usually grab only 1-2 hyips lately but study them carefully!

What is the right percentage to save from your monthly income ? | NewProxyLists

well , that’s right , but i’m sure you will buy all of your needs at once , for example : food , you’ll buy the required food that will be enough for a whole month , so you’ll have to buy that only once a month , there are other things to be expected , like for example if you have a car , you don’t know when it will be broken or anything like that

php – Monthly search value in adwords api is much larger then in a Keyword Planner

I am trying to use an adword api to get some keyword statistics. But what I see is that with a same parameters my monthly search volue is about 7 mln searches. While adword keyword planner shows around 400-500. I can provide php code with parameters I am setting.
Network settings:

$networkSetting = new NetworkSetting();
        $networkSetting->setTargetGoogleSearch(true);
        $networkSetting->setTargetSearchNetwork(false);
        $networkSetting->setTargetContentNetwork(false);
        $networkSetting->setTargetPartnerSearchNetwork(false);

Language is set to Russian following way:

 $languageParameter = new LanguageSearchParameter();
        $english = new Language();
        $english->setId(1031);
        $languageParameter->setLanguages(($english));
        $searchParameters() = $languageParameter;

Location is set to Ukraine:

$loc = array();
        $location = new location();
        $location->setId(2804); // Ukraine
        $loc()=$location;
        $locationTargetParameter = new LocationSearchParameter();
        $locationTargetParameter->setLocations($loc);
        $searchParameters() = $locationTargetParameter;

What Am I missing?

I felt it necessary to open up this ticket due to the absolutely excellent support I received from Alex. In fact, I had made it all the way to checkout and then decided not to finalize the purchase due to the fact I didn’t like the auto renewal I was being forced to accept.

A short time later, I clicked on one of your emails and entered the client area. After opening the chat window, I had a brief conversation with Alex and was thoroughly impressed. Now let me be clear. When I feel as though I have gotten bad service, I believe it is my responsibility to report it so that a business can take whatever action they deem fit to improve service. At the same time, if I can complain, I also have the responsibility to compliment service that is better than expected.
