How can I reliably determine the type of a variable that is declared using var at design time?
...art by transforming it syntactically to
var z = y.Where(foo=>foo.
In order to work out the type of foo we must first know the type of y. So at this point we ask the type determiner "what is the type of y"? It then starts up an expression evaluator which parses x.ToCharArray() and asks "what's...
How to check if an object is a list or tuple (but not string)?
This is what I normally do in order to ascertain that the input is a list / tuple - but not a str . Because many times I stumbled upon bugs where a function passes a str object by mistake, and the target function does for x in lst assuming that lst is actually a list or tuple .

...ble over there?" and "did I get these procedures to execute in the correct order?". Seriously, you get these benefits (from understand the FP paradigm) in Python, C#, C++, Java, you name it.

Using a Single Row configuration table in SQL Server database. Bad idea?
...fferent settings: all I had to do was add a "client_id" PK to the table in order to maintain a separate set of settings for each client. (This is when you realise that these "settings" are really just attributes for a higher-level entity you haven't modelled yet.)

Deleting lines from one file which are in another file
...print }' exclude-these.txt from-this.txt
The output will be in the same order as the "from-this.txt" file. The tolower() function makes it case-insensitive, if you need that.
The algorithmic complexity will probably be O(n) (exclude-these.txt size) + O(n) (from-this.txt size)

Detecting 'stealth' web-crawlers
...s, you can put a div under another, with CSS (placing it first in the draw order) and possibly setting the z-order. A bot could not ignore that, without parsing all your javascript to see if it is a menu. To some extent, links inside invisible DIV elements also can't be ignored without the bot par...
JavaScript curry: what are the practical applications?
...ents and a function, describing how the element should behave, to a higher order function that will ensure all the timing stuff, its generally easier for the customer to release, as public API some function like "slideUp", "fadeIn" that takes only elements as arguments, and that are just some currie...

...th the same name; and if so, all elements are posted, and I'm not sure the order is actually defined (though likely to be simply in page order in practice). Using the word "false" as the value is somewhat misleading, so yeah, it's a WTF - a better, less misleading choice would have been something l...

You could also use findAny() instead of findFirst() if you don't necessarily care about getting the first matching player from the (ordered) stream but simply any matching item. This al...
