Southeast / Re: Interstate 73/74

FHWA requires full movement at all Interstate interchanges (with very few exceptions) hence the redundant ramps.

Is this something introduced in the last 15-20 years, in which the interstate-to-interstate connection must include direct ramps between all directions?

I ask this because I can think of many interstate-to-interstate junctions that don't have this, usually a bypass route and its parent (i.e. for a California example, I-405 and I-5 at both ends in Sylmar and Irvine respectively, in which Route 118 and Route 133 serve the missing movements nearby).

There are some examples of Interstate-to-interstate in North Carolina that do not have this:

I-40/former I-85 (US 29) in Greensboro, in which the missing 85 north to 40 west move was covered by US 220. Junction was built when both routes were Interstates, before the Greensboro urban loop/I-840 happened

I-285/I-85 in Lexington, grandfathered in as I-285 was not originally interstate.  Standard Y junction

I-40/I-840/I-85 in eastern Greensboro, I-40 east from the Death Valley section does not have any ramp to 85 south

I-795 and I-587, though the Interstate designations came after both freeways were originally constructed.

What sort of witchcraft is being performed to make a network socket behave like a file? Makes file transfer really freaking easy in C.

That's how Unix works—everything is a file, even devices. (Look in your /dev directory and there they all are.) You send data to a device by writing to the file that corresponds to the device. This means you can do some kind of amazing stuff very simply. You can make a white noise generator by reading /dev/random and writing it to the speakers, for instance.

Since C is native to Unix, it just kept the same metaphor.

Central States / Re: Cashless Tolling coming so...

I'm a little surprised that the Turner will not be the last to go cashless as it is the most traveled rural turnpike in the state and believe the plan was for it to convert last. There was an accident at one of the toll booths near Stroud recently, and I wonder if that pushed the Turner Turnpike to convert earlier than originally planned.

I believe this was always the plan from day one whenever that was.

Mountain West / Re: I-40/US 93 West Kingman In...

And what of the part north of this interchange?  There's even a traffic light.

That signalized intersection will (eventually) be replaced by an interchange. I was talking about the part from US 95's East Junction with I-40 south through Wikieup to just north of Wickenburg.

You mentioned the whole corridor at the end of your post and seemed to imply that this interchange was the only thing preventing I-11 from being signed from I-40 to the Nevada border.  To get that finished, they would also need to address the stuff north of I-40, and quite a few more things to the south, not "just" the ones you listed.

AZDOT needs to fucking get with it, IMHO.

Southeast / Re: Interstate 73/74

I don't get the need for full access at all 3 interchanges.

I was wondering this as well. Who is going from I-40 westbound to I-74 westbound or eastbound, or I-74 (either direction) to I-40 EB? There are no plans to continue the beltway south/west, right? Seems like a massive interchange for very little traffic.

I agree... I can understand the ramps for redundancy, but 2 lane flyovers seem a bit excessive. Well... at least they will never be congested!

FHWA requires full movement at all Interstate interchanges (with very few exceptions) hence the redundant ramps.

NCDOT standard design for flyovers is two lanes because widening the structure later is nearly impossible.

Why not loop ramps with C/D ramps?

The only other bridge i was on before a disaster was the I-94/Middlebelt road bridge before August 1987. While the Bridge was not destroyed in the crash of Northwest 255, the bridge took some minor damage from the crash and was replaced during reconstruction of the ramps around Metro Airport in the 90s.

(when I got to the end of K&R, I was like...wait, that's it? that's the whole language?)

When I was in college, that book was (only half) jokingly referred to as "the Bible".  I still have it after all these years, even though at this point the odds of me doing anything in C are slim to none.  The C language does have a certain elegance that many other languages lack.

I pull it out and read it cover to cover from time to time, even when I'm not planning on writing any C any time soon. So many modern languages (especially the two I write the most code in, Perl and PHP) lean so heavily on what C does, that it's helpful to refresh my knowledge of C even if I'm not writing in it.

Hey, I actually printed out this book to self study! I'm amazed at how it also teaches you to be a better programmer (like avoiding magic numbers -- replace fixed constants with symbols, so it's easier to change these constants later) while teaching you the language. Obviously some of it is outdated, namely anything involving floats being simplified with C99.

I think one of the neatest tricks with (Unix like) C is how basic system calls like read(), write(), open(), and close() can be used for both files and network sockets. What sort of witchcraft is being performed to make a network socket behave like a file? Makes file transfer really freaking easy in C.

I found a silly item in my profile that won't seem to go away.

The username info in the Skype field doesn't seem to fully disappear; you can remove it, but then it eventually comes back after any profile changes.

I forget if I ever actually filled in that information because I haven't used Skype in over 10 years.

I just manually removed it for you.  Hopefully this will stick.
