When you have a data stream, are you easily able to map it to a physical sensor? Couldn't you just maintain the full sensor map without re-creating the entire dictionary every time that you see a new sensor?

The data stream includes the physical sensor number. Not sure what you mean by a "full" sensor map, if every application used all the sensors then this wouldn't be an issue. The issue is to figure out which subset of the sensors is currently in use.

I don't know why we're still talking about this. As I mentioned earlier, I figured out a way to ask for the number of sensors in use without requiring the user to enter it, so my new method doesn't involve catching exceptions or re-creating dicts:
1. Ask how many sensors to expect.
2. Keep track the sensors I've encountered.
3. When I've encountered the expected number of sensors, create the logical-physical mapping and switch to the normal data handler.

Yup, this is an image, in full WPF XAML, that does exactly what a rectangle can do. And the color is literally the color Gray. As in the preset colors you can use for a rectangle fill Gray.

Well now if you want to change the color you just update Gray.bmp to be blue, duh

Perhaps more astonishingly, this exact method and image are used to set the background color of buttons elsewhere. Instead of, y'know, Background="Gray".

It's a non client facing utility and if I recall correctly the color definitions are from X11, so I would be more worried of interns changing images haphazardly. :v:

I can't believe I wrote this. To be fair it was over two years ago. It's a miracle this hasn't broken until today when someone put a non-UTF8 character in the json

code:

string sendData = entity.jsonSendData;

WebRequest request = WebRequest.Create(referenceCheckURL);

request.Method = "POST";
request.ContentType = "application/json";
request.ContentLength = sendData.Length;

Stream requestStream = request.GetRequestStream();
requestStream.Write(System.Text.Encoding.UTF8.GetBytes(sendData), 0, sendData.Length);
requestStream.Close();

e: also the lack of usings.

I'm convinced it's a product that was made by a group of interns in 3 months that the marketing guys managed to get a hold of and sell to every large company on the planet. It's not uncommon for me and my coworker to ask each other "Why did you do this?" and the answer is usually "Because SharePoint." Here's a beauty in our current codebase:

C# code:

foreach (SPSite site in WebApplication.Sites) using (site)
	{
		foreach (SPWeb web in site.AllWebs) using (web)
			{
				ProcessWeb(web);
			}
	}

The properties Sites and AllWebs automatically instantiate connections to the sites or webs which you then have to dispose of yourself. This happens every time you access the property. Who the hell decided to make that a property and not a method? Also, what's up with the naming? Why not AllSites, or maybe just Webs, so we could have some drat consistency?

Whoops, had it backwards. Expecting ASCII, got UTF8. Even though I'm using UTF8 GetBytes. Guess I picked one at random, said "eh it works" and moved on.

It was a thing that made the length of the string different from the length of the bytes.

So the stream got cut off early because I was measuring the string length and not the byte length.

Because SPWeb.Webs returns only the child sites of the current site. Sharepoint naming conventions are already bad enough without putting two completely different functionalities under identically named properties.

Another Sharepoint horror: Violating the design contract for the IDisposable interface. For example, SPLimitedWebPartManager implements IDisposable. But in addition to wrapping the SPLimitedWebPartManager in an using block, you must also dispose the SPWeb exposed by the Web property manually.

SPDisposeCheck saved us a lot of trouble, and I've configured it to be run in every Team Build that I'm responsible for.

While you're in there you might as well change things to support all Unicode, as json is defined to be unicode by rfc4627.

code:

3.  Encoding

   JSON text SHALL be encoded in Unicode.  The default encoding is
   UTF-8.

   Since the first two characters of a JSON text will always be ASCII
   characters [RFC0020], it is possible to determine whether an octet
   stream is UTF-8, UTF-16 (BE or LE), or UTF-32 (BE or LE) by looking
   at the pattern of nulls in the first four octets.

           00 00 00 xx  UTF-32BE
           00 xx 00 xx  UTF-16BE
           xx 00 00 00  UTF-32LE
           xx 00 xx 00  UTF-16LE
           xx xx xx xx  UTF-8

The scripting language interface for the IRC client weechat is pretty awesome:

quote:

As you probably know, there is not really "pointers" in scripts. So when API functions return pointer, it is converted to string for script.

For example, if function return pointer 0x1234ab56, script will get string "0x1234ab56".

And when an API function expects a pointer in arguments, script must give that string value. C plugin will convert it to real pointer before calling C API function.

Empty string or "0x0" are allowed, they means NULL in C. For example, to print data on core buffer (WeeChat main buffer), you can do:

weechat.prnt("", "hi!")
Warning
In many functions, for speed reasons, WeeChat does not check if your pointer is correct or not. It�s your job to check you�re giving a valid pointer, otherwise you may see a nice crash report

Internet Janitor: May 17, 2008; "That isn't the appropriate trash receptacle."

A homework problem asked students to write a simple function which determines whether a number is divisible by 2 or 3. Some wrote it like this:

code:

(define (div23 v)
  (or
   (equal? 0 (modulo v 2))
   (equal? 0 (modulo v 3))
  )
)

And then there was this approach:

The latter. Students are mostly third-year CS students with some experience programming in imperative languages, but many have never used a functional language before. My sincere hope is that most of the overly complicated solutions I've seen so far are a result of wanting to show off.

Well, obviously you can do it by determining what the number is mod 6. If it's 0, 2, or 4, it's divisible by 2, and if it's 0 or 3, it's divisible by 3.

code:

(define (div23 n)
  (if (>= n 6)
    (div23 (- n 6))
    (not (or (= n 1) (= n 5)))))

Instead of taking n/2 + n/3 = 5n/6 time, it takes n/6 time, so it's 5 times as fast!
