Answer : Leaving SQL aside for a moment... A relational operator takes one or more relations as parameters and results in a relation. Because a relation has no attributes with duplicate names by definition, relational operations theta join and natural join will both "remove the duplicate attributes." [A big problem with posting examples in SQL to explain relation operations, as you requested, is that the result of a SQL query is not a relation because, among other sins, it can have duplicate rows and/or columns.] The relational Cartesian product operation (results in a relation) differs from set Cartesian product (results in a set of pairs). The word 'Cartesian' isn't particularly helpful here. In fact, Codd called his primitive operator 'product'. The truly relational language Tutorial D lacks a product operator and product is not a primitive operator in the relational algebra proposed by co-author of Tutorial D, Hugh Darwen**. This is because th...

Answer : According to http://minecraft.wikia.com/wiki/Ender_Chest, it does work that way. If two Ender Chests are placed and two of an item was put in one, when the chest with the items in is opened, there will be one of the item in that chest and one of the same item in the other chests, acting as an image. This feature also works among the different worlds: Overworld, Nether, and the End. Yes , your items will be transported anywhere in the world, including The End, The Nether, or anywhere else. Be careful, though, that what you placed in an Ender Chest can only be picked up by you, and nobody else. So you can't transfer your items to your friend this way. Yup, they work between dimensions transferring itens.

Answer : You can only install a language pack at install time in VS 2017 RC. To install RC with a different language: Open the Visual Studio Installer. Find an addition under "Available" and click Install Click on the "Language packs" tab and select a language You can have multiple instances of VS 2017 side by side so this shouldn't interfere with your other installation. Disclosure: I work on Visual Studio at Microsoft. Go to Tools -> Options Select International Settings in Environment and on the right side of a screen you should see a combo with the list of installed language packages. (so in my case Czech, English and same as on MS Windows ) Click on Ok You have to restart Visual Studio to see the change...

Answer : From the Putty FAQ: To run a PuTTY session saved under the name ‘mysession’, create a Windows shortcut that invokes PuTTY with a command line like \path\name\to\putty.exe -load "mysession" ---EDIT--- In Windows 7, the shortcut has to be in quotes like this: "\path\name\to\putty.exe" -load "mysession" I had referred to Putty Connection Manager as a useful addon, giving one click connects and tabbed windows, but it seems the app is dead and all the files removed from the hosting site. While checking into this, I found a fork of the project, called superputty (see below) and a reference to KiTTY - a Win32 native version of PuTTY with extra features so here you go: Superputty:https://github.com/jimradford/superputty KiTTY: http://kitty.9bis.com/ In windows use this target for putty shortcut, for save username and password. Then load a saved session or add to Task Manager: "C:\Program Files\PuTTY\putty.exe" -load ...

Answer : Didn't read most of you post, sorry. But just fixing on the final little question what is the ASCII key code for Tab? ASCII value for tab is 9 (decimal or hex), so try Alt + ( Numpad 0 , Numpad 9 ). But, I've just tested doing so in this very edit box and it doesn't work, but it does in notepad, MS Word, etc. I wonder why...? Anyway, if you really need a tab somewhere odd, try copying one from notepad and pasting it where you need it - that's what I tend to do. Edit If you're doing this for it to be displayed on a website (which is what I think you're implying), a tab character may be ignored because HTML tends to ignore whitespace (outside of pre blocks, etc). If it is HTML you could also use the HTML entity version &#09; as well, but this will function in the same way. The code is ALT + 0 0 9 However, I don't think it will accomplish what you are after. Hope this helps you -- you have quite a long question :-) Wikipedia ...

Answer : Solution 1: Launch ACTION_SEND Intent When launching a SEND intent, you should usually wrap it in a chooser (through createChooser(Intent, CharSequence)), which will give the proper interface for the user to pick how to send your data and allow you to specify a prompt indicating what they are doing. Intent intent = new Intent(); intent.setAction(Intent.ACTION_SEND); # change the type of data you need to share, # for image use "image/*" intent.setType("text/plain"); intent.putExtra(Intent.EXTRA_TEXT, URL_TO_SHARE); startActivity(Intent.createChooser(intent, "Share")); Solution 2: Use ShareActionProvider If you are just looking to add a Share button in Overflow Menu, also have a look at ShareActionProvider. public boolean onCreateOptionsMenu(Menu menu) { getMenuInflater().inflate(R.menu.share, menu); MenuItem item = menu.findItem(R.id.share_item); actionProvider = (ShareActionProvider) item.getActionProvider(); // Cre...

Answer : I think that you are right with keeping your test data separate from tested application. You can fix problem with Null by creating files directory for Instrumentation app by executing the following commands adb shell cd /data/data/<package_id_of_instrumentation_app> mkdir files You can do above only on emulator or rooted device. Then test from your question will not fail. I did it and also uploaded file named tst.txt to files dir, all below tests were successful: assertNotNull(getInstrumentation().getContext().getFilesDir()); assertNotNull(getInstrumentation().getContext().openFileInput("tst.txt")); assertNotNull(getInstrumentation().getContext().openFileOutput("out.txt", Context.MODE_PRIVATE)); But I think more convenient way to provide data to test project is to use assets of test project where you can simply save some files and open them: assertNotNull(getInstrumentation().getContext().getAssets().open("asset.txt"))...
