I am trying to find credit cards using FTK - grep

I am doing an assignment where we have to find 5 voyager credit cards using an image file given to us by our professor. The credit cards all start with 8699 and end with 1-5. We are using FTK 1.81.6
8699\d{11}[1-5]
This is what I came up with to find them but when I search I get no results.

return #ERROR Formula Parse error when trying to access data from a 2nd Sheet on the same file

I'm pretty new to using Excel/Google Sheets as I've never needed it in previous jobs. This query isn't for a work project but for a personal record to keep information I want to record clear and concise, Kind of like keeping books for a business I am trying to record various income's and outgoing's in the form of "points" (Maybe Google Sheets isn't the best "free" tool to use) that will show how many "points" someone has accrued, How they earned them, and What if any they have spent them on, It will also be recording some cash transaction as well.
I have 2 sheets currently and I am trying to add all the data for a single person from 1 Sheet into the "Points Total" column on the other sheet taking into account what they have earned and what they have spent.
I'm not sure how else to explain it really, Here is my current butchered (seriously) formulae:
=sum(C2:F2), - 'Point Purchases'!C2
Link to the Google Sheet in question
You are mot that far off. Just remove the comma.
=sum(C2:F2) - 'Point Purchases'!C2

Trying to paste a lowest price from G2A onto google sheets

So I am trying to learn how to get the lowest selling price data from g2a games and put it onto google sheets. I tried the code below for Next car Game on G2A but get an error saying imported content is empty.
=IMPORTXML("https://www.g2a.com/next-car-game-early-acces-steam-cd-key-global.html","//div[#class=mp-Price]")
I am very new to this but hope to learn off of this
It is loaded by a separate json file through jquery. I found the source url but you will still have to parse out that data and then compare lowest rates potentially
=TRANSPOSE(IMPORTDATA("https://www.g2a.com/marketplace/product/auctions/?id=5759&v=0"))

Getting a sum from Parse with Parse Cloud Code (for iOS app)

I'm new to Parse Cloud Code and am struggling with a seemingly simple task.
I'm working on a small iOS game where the users can choose from a list of characters to play -- imagine mario or luigi. In addition to tracking user scores in the game, I'm tracking total points for each character in Parse, so I can display a "mario" total and a "luigi" total (from all users.)
There could be multiple users playing at once (I hope), so I don't have Parse saving to just one mario and one luigi counter. Instead, each user gets a running count of their own mario and luigi scores.
So how do I pull the total marioPoints and total luigiPoints?
Parse doesn't have SQL-styled querying, so I've been looking at Parse Cloud Code and their "average stars" example (https://parse.com/docs/cloudcode/guide#cloud-code) looked kind of close at first glance:
But I can't get it sorted. And even if I could, it's limited to 1,000 responses, which wouldn't be enough. (I'm optimistic.)
Thanks!
Your best option is to keep a running total when any individual user update is saved. Do that using a save hook and the increment( attr, amount ) function.

Collecting follower/friend Ids of large number of users - Twitter4j

I'm working on a research project which analyses closure patterns in social networks.
Part of my requirement is to collect followers and following IDs of thousands of users under scrutiny.
I have a problem with rate limit exceeding 350 requests/hour.
With just 4-5 requests my limit is exceeding - ie, when the number of followers I collected exceeds the 350 mark.
ie, if I have 7 members each having 50 followers, then when I collect the follower details of just 7 members, my rate exceeds.(7*50 = 350).
I found a related question in stackoverflow here - What is the most effective way to get a list of followers using Twitter4j?
The resolution mentioned there was to use lookupUsers(long[] ids) method which will return a list of User objects... But I find no way in the API to find the screen names of friends/followers of a particular "User" object. Am I missing something here.. Is there a way to collect friends/followers of thousands of users effectively?
(Right now, I'm using standard code - Oauth authentication(to achieve 350 request/hour) followed by a call to twitter.getFollowersIDs)
It's fairly straightforward to do this with a limited number of API calls.
It can be done with two API calls.
Let's say you want to get all my followers
https://api.twitter.com/1/followers/ids.json?screen_name=edent
That will return up to 5,000 user IDs.
You do not need 5,000 calls to look them up!
You simply post those IDs to users/lookup
You will then get back the full profile of all the users following me - including screen name.

Quickbooks: Adding a negative value to an invoice using the QBDSK

Is there any way to add a line item containing a negative amount to an existing invoice?
I'm using QBSDK7 and QB Enterprise. (and if it matters .Net 3.5)
What we're attempting to do is automate the way we're creating invoices. We're already pulling in employee's time and applying it to the correct invoices, but when we go to add credits (just a negative amount on a line item on the invoice) using
InvoiceLineMod.Amount.SetValue(-1234)
it fails with the error "Transaction must be positive"
I've also tried adding a Service Item with a negative amount and giving it a positive quantity and I get the same result.
This seems like such a no-brainer as we have been doing this manually for the last 10 years. I'm guessing there is artificial restriction on this.
Some things to consider:
Credit Memos are no good as we need to display exact details of the reduction on the same page.
We don't have payments to apply yet in most cases.
This need to be done before any retainers are applied.
Any help would be greatly appreciated.
Can you show the complete code you're using to modify the invoice? Can you also show the exact error message you're getting?
It is possible, though to do you need to make sure that you're using a Discount Item as your ItemRef type (a Service Item will not work), and you need to make sure that the transaction as a whole is for a positive amount.
Sometimes our app has to adjust an invoice down with a negative number. I have been able to add negative line items using the following code. I have to set a quantity and a rate, instead of setting the amount.
IInvoiceLineAdd ila = ia.ORInvoiceLineAddList.Append().InvoiceLineAdd;
ila.ItemRef.ListID.SetValue(GetQBID(JobKey));
ila.Desc.SetValue("Adjustment");
ila.Quantity.SetValue(1);
ila.ORRatePriceLevel.Rate.SetValue(-1.00);
Quickbooks doesn't allow you to post an invoice with a negative balance. If you try to do it through the UI, it prompts you to create a credit memo instead. (And vice-versa if you try it with a credit memo.)
You can enter negative quantities and/or prices into the line items, but the total of the invoice has to be >= 0 or it won't post (i.e., add other line items that offset the negative amounts).
The solution is to use credit memos. Your client-side processing will be more complicated, but it's the only choice with Quickbooks.
