## db2 – Cross Database Queries using IBM Data Studio

For you to execute any SQL statement you have to be connected to some database server; Data Studio does not execute SQL statements. Subsequently, for the three part name (`<server>.<schema>.<object>`) to work the server you’re connected to has to know what the `<server>` part is.

In the simple case of accessing objects in a database that belongs to the same Db2 for LUW database instance, `<server>` is the other database name, and no additional setup is required.

However, if the other table is in a database managed by a different instance, or if it belongs to a different DBMS (Db2 for z/OS, Oracle, etc.), you will need to set up a federated data source, whose name you will then use for `<server>`.

## automation – Google Docs: How to automate Enumeration and Cross referencing Exhibits

Given a series of three photos: Alpha, Gamma, Delta. and they are enumerated in two sentences:

Exhibit 1 is a photo of an Alpha specimen, where as Exhibit 2 is a
Gamma specimen. Recently a new specimen was found as shown in Exhibit 3,
which has been identified as a Delta specimen.

Is there a feature that enable one to automate the enumeration Exhibit n and renumber subsequent instances of Exhibit n+1? I ask because should I insert a new sentence for a photo of Beta. For example, I would like to insert the sentence:

A common specimen misidentification is shown in Exhibit 3 which is known as Beta.

The result should automatically renumber: 3 -> 4

Exhibit 1 is a photo of an Alpha specimen, where as Exhibit 2 is a Gamma specimen. Recently a new specimen was found as shown in
Exhibit 3, which has been identified as a Delta specimen. Recently a new specimen was found as shown in Exhibit 4, which has
been identified as a Delta specimen.

Again feature shall automatically increment the final instance of Exhibit n from 3 to 4 when the new exhibit 3 is inserted.

I think Microsoft Word has automated sequential elements. Naturally, Google Docs has its own lexicon: what does Google Docs call this functionality. Any reference links to tutorials / references etc. are appreciated. Thank you

The preference is not to use add-ons if possible

Upon a little more thought, maybe it makes sense to create the figures first and enumerate them, then crosslink them back into text / prose?

## lenovo – Advice on setting up cross compilation tool chain for Android 10 SDK29+?

I have a simple ‘helloworld.c” that I want to run from ADB shell then eventually create an app that can display it on my device.
Im quite new to C, Linux, Android, cross compiling, libraries in terms of real world results but Iv been doing a hell of a lot of reading and am getting used to my Linux (full install). I realise following various tutorials can be misleading due to the fact of outdated software / differnet hardware as I am attempting the above challenge on a relatively new device with relatively new hardware “android 10 R”. I could just do with some ‘best practice’ advice on choosing the correct libraries and tool chain setup.

I understand making the ‘helloworld’ as an app is more complicated requiring use of Android NDK, so first step is to get it working within ADB shell.

Device – Lenovo M8 FHD android 10 R

aarch64

armv8l ( returned from ADBShell> uname -m )

SDK29

Installed libraries –

ii g++ 4:9.3.0-1ubuntu2 amd64 GNU C++ compiler

ii g++-9 9.3.0-17ubuntu1~20.04 amd64 GNU C++ compiler

ii gcc 4:9.3.0-1ubuntu2 amd64 GNU C compiler

ii libxkbcommon0:i386 0.10.0-1 i386 library interface to the XKB compiler – shared library

Firstly is the aarch64 above the correct cross compiler for my device?
Any clarification on how to make sure I have JUST the tools I need for getting helloworld in shell including relevent versions that work with SDK29 ?

So far when I try to run my cross compiler helloworld.c from shell I get – file not found error.
I have googled for many answers on this error and believe its a compilation error, so now Im just lost in libraries! and what did I do wrong. I think the tutorial I used has mislead me to wrong cross compiler choice, I don’t know?

ps I will try and clean this question up.
also I understand LLVM could help my problem but is this still experimental ?

## What expect when cross processing in ECP-2d developer?

I found some fresh ECP(-2d) chemistry rather cheap, and was wondering if anyone knew what to expect when cross processing C-41, E6 or ECN film in ECP (-2d) chemistry.

## uk – How can I cross the English channel with a car?

To cross the Channel with a vehicle, you have two choices: ferry or train. The ferry costs less and takes longer, the train faster and more expensive. Folkestone is the departure point for the Eurotunnel train to Calais; the most popular ferry crossing is Dover-Calais.

Here’s an overview of some of the options:

To France, the choices are Dover–Dunkerque, Newhaven-Dieppe, Portsmouth to Le Havre, Caen, Cherbourg, or St Malo; Poole-Cherbourg, Plymouth-Roscoff.

The ferry route from England to Belgium is Hull-Zeebrugge. For the Netherlands, Hull-Rotterdam, Newcastle-IJmuiden, Harwich-Hoek van Holland.

As for convenience, that depends on where you start your journey and where you’re heading.

## Solve Matrix equations with Cross Product: weird system of equations

I would like to find the values {Pfx, Pfy, Pfz} that satisfy the equation A X B = C . The code of everything is at the end, I want to ilustrate with images what i think of first:

A is this:

B is this: {0,0,0}

And C is this: {100,500,200}

The image of the complete code is this one:

My variable here are {Pfx,Pfy,Pfz} and the {i,j,k} are the unit vectors. The way that the matrix is shown in the picture corresponds with a trick used to solve in papper this type of matrix.

The solution would give me the value of Pfx in the “x” coordinate (and this would be expressed by Pfx being multiplied with the i vector). And the same mechanism applies with Pfy related with j Vector ; and Pfz related with k.

The problem here comes with the fact that the I can`t find the values {Pfx, Pfy, Pfz} that satisfy the equation A X B = C.
I am not sure if the problem lies in the “LinearSolve” comand, in the use of the CrossProduct or in the use of the versor {i, j, k} inside the matrix.

Any kind of help in this regard will be extreamly useful, thanks in advance!!

Code:

``````i := {1, 0, 0}

j := {0, 1, 0}

k := {0, 0, 1}

LinearSolve(({ {i, j, k},{1, 2, 3},{Pfx, Pfy, Pfz}})(Cross)({{0},{0},{0}}) == ( {{100},{500},{200}} ))

## firebase – Best database for cross platform apps

I’m currently developing a cross-platform app (Android, IOS and Web) which stores and sync data across all the platform.

I want to log the transactions made by each user separately in a user table/collection. Which is the best DB to use SQL or NoSql I’m also considering Firebase but the cost is the main concern.

data structure

``````{
"Name":"Name",
"Price":800.70,
"TxnId":"07ddfdf",
"Buy":{"Price":100.0,"Volume":100},
"Sell":{"Price":110.0,"Volume":100}
"Tax":18.0
}

## What is the Cross Entropy Loss for this output?

Suppose you flip a coin 5 times each with equal probability (let us say 50%, for all 5 coin flips), Would the cross entropy of the function be 1 due to them having no difference in values?

## Equation of motion in terms of cross product

I have this assignment which i am struggling with and i hope someone here are able to help me.

The reference in problem 2 ($$^3$$) is to any physics books or even https://en.wikipedia.org/wiki/Rotating_reference_frame

I am struggling big time with problem 2 and 3 🙁 Anyone who can help me out?

Thanks

## Cross Domain Tracking

Hi everyone,

Is it necessary to use the cross domain tracking in Google Analytics if the subdomains are under the same domain?
