Format a Textview which lists all SQL table entries in Android Studio

android,sqlite,android-studio

You can do two things. Using attributes like android:padding and android:margin on your TextView to position the text where you wish on the page. You can then also separate the "columns" in text using tab characters between each value on a line. String s1 = c.getString(0); s1 = s1.replaceAll("\\s","\t"); This...

Matlab - Eliminating for loops

matlab,for-loop

Typically you cannot get rid of a for-loop if you are doing a calculation that depends on a previous answer, which seems to be the case with the J_last-variable.

Why does my script only save one out of the 40 objects that I insert?

python,sqlalchemy

You're closing the session inside the for loop, so nothing will happen on it in the subsequent iterations. Actually it's worse than that, since you're returning the item inside the loop, meaning the loop won't even execute the rest of the iterations. Move the rollback/close handling outside the loop. Move...

Is this Blade sanitation working correctly (double vs triple curly braces)?

Your test is basically confusing ticks with milliseconds. If you only need to store a number of milliseconds since the unix epoch, then do so - but I'd recommend using something like this to perform the conversion: public static readonly DateTime UnixEpoch = new DateTime(1970, 1, 1, 0, 0, 0,...
