I think the starting point is the ambiguity of the standard "Name all 50 states" challenge. I'm no native speaker but "Name" means both "invent a new name" and "give the correct name for", and Randall is misunderstanding this on purpose. Maybe that's obvious to some, but it seems the sort of thing worth explaining here?--[[User:Blaisorblade|Blaisorblade]] ([[User talk:Blaisorblade|talk]]) 09:02, 2 December 2016 (UTC)

"Colocated" is technically misspelled (it's either "co-located" or "collocated"), though that could be for the sake of matching it to "Colorado." However, the word is used in many situations other than "co-location center" (e.g. workers being collocated in the same office), so unless Colorado is particularly notable for its co-location centers, I don't think it makes sense to claim that that's what it's specifically referring to. –[[User:PhantomLimbic|PhantomLimbic]] ([[User talk:PhantomLimbic|talk]]) 09:36, 2 December 2016 (UTC)
:Hmm, it looks like "colocated" is a spelling used specifically within the industry, so perhaps the claim is warranted after all. –[[User:PhantomLimbic|PhantomLimbic]] ([[User talk:PhantomLimbic|talk]]) 09:50, 2 December 2016 (UTC)

I think the challenge is supposed to be a blank map that someone has filled out in red pen.

Dear, it's old to complain of xkcd's various quality drops, but I think this is my turn. A good number of recent comics have just been variously exaggerated text lists of stuff. Randall might just as well switch to a written format; pictorial context is becoming less and less necessary for his comics by the week. <nowiki>~~~~</nowiki> {{unsigned ip|162.158.203.149}}

:When I last moved house, I methodically labelled every single box with it's exact contents. Several meticulously itemized boxes contained (amongst other things) stuff like "Acrylic art paint", "Rodent poison" and "Adhesives" - and the movers saw this and refused to move about a dozen boxes because they contained things that are liquids or hazardous materials. This was more than I could fit in my car - so this became a huge deal. So next time, I'm going with "Normal House Stuff". Seriously - just label them with the room you want them dumped in at your new home and a number...write the actual contents in a MySQL database...preferably with a photo of the box before you taped it up.

The explanation for Bison says they're "also known as buffalo". Not sure if that's technically accurate. https://en.wikipedia.org/wiki/Bison Excerpt: "Although sometimes referred to historically as a "buffalo", it is only distantly related to the true buffalo."

172.68.78.133: Kids today have it easy

[https://www.ece.cmu.edu/~ganger/712.fall02/papers/p761-thompson.pdf Reflections on Trusting Trust] (pdf), Ken Thompson's acceptance speech for the 1984 Turing Award, in which he discusses creating a backdoor in the C compiler (yes, there was only 1 when he invented the language) that itself creates a second backdoor in the login program when it is compiled. Additionally, it reproduces itself when compiling the C compiler from un-tampered-with source code, so that anyone using the binary (compiled) compiler would be unable to avoid reproducing the backdoor in all its forms. This is the sort of thing that gives security programmers nightmares. [[Special:Contributions/108.162.221.168|108.162.221.168]] 04:52, 4 November 2016 (UTC) (bonsaiviking)

The "4-6 weeks" thing might be a reference to high-performance computing, in particular scientific calculations, a few decades back. From what I've heard from older people in my scientific field (I'm too young to have experienced it myself), you'd prepare your program on punch cards, mail these to an institution owning a fast computer (because your group or university didn't have one), and they'd run the program and mail the result back to you. This, I've been told, took a few weeks. Maybe someone with first-hand experience can give more information. [[Special:Contributions/141.101.104.98|141.101.104.98]] 10:34, 4 November 2016 (UTC)

Source Code on Punched Cards: As an undergrad at Durham Uni I remember punching PL1 source code onto cards to be inserted into a batch queue to be compiled and run on an IBM360 at the nearby city of Newcastle, overnight.

At the risk of emulating Dilbert's "Topper", I remember at school writing programs on coding sheets (effectively squared paper; one character in each box), which would get sent to the local university, where they would be punched onto cards and run on the mainframe. The following week, you'd get your coding sheets back, plus the cards and the printout from your batch job. Then you'd make your corrections, also on coding sheets...

I'm reminded of Frank Hayes' song, "When I Was a Boy": "And we programmed in ones and in zeroes / And sometimes we ran out of ones!" On a more serious note, C came out in the late seventies, and I was using punch cards as late as 1975. That's not "long" before, and I wouldn't be too surprised if there were C compilers that accepted punched card input.

: Punch cards 79-80 in the U.S. for C programming. We did have text editors too for other languages, but we'd punch up and submit decks to a queue for batch processing. Usually only waited minutes (though the when big projects were due, it could take an hour - the bad part was there wasn't any way to stop an infinite loop until the job limit ran out. We were given so much in "computer dollars" for the class (because the machines were also used for outside work for real money) and you'd have to ask for extra if you used it up. I miss the green bar paper though. [[User:Afbach|Afbach]] ([[User talk:Afbach|talk]]) 18:25, 4 November 2016 (UTC)

Is there a parallel here between computing and real life? For example, panel 3 mimics real life garbage collection, where you let your trashcan pile up before collection. Similarly, without texting in the 'old days' you would have had to mail stuff to people whereas to do things we can do in seconds now. So she's using his views of the {{unsigned|ExplainBot}}

I think the punched cards explanation is missing the point that C (or any language, that I know) didn't _require_ that it be on punched cards. I.e. there was nothing in the language specification that prohibited the program from being on paper tape, mag tape, disk, etc. [[Special:Contributions/162.158.74.70|162.158.74.70]] 14:22, 4 November 2016 (UTC)Pat

: I strongly echo 141.101's recollections. The second panel of 1755 is not far from the truth.

: I wrote my first program in FORTRAN IV in 1972 in an "enrichment" class at my school in Worthing - in the south of England (it calculated the average of 10 numbers). We wrote the programs out by hand on 80 column "coding forms" which were then snail-mailed to the regional computing center. When their keypunch operators had time, they'd punch our programs onto cards. On the following night, after the payroll software had been run, they'd stick our cards into the batch queue of their over-worked IBM 360. If they compiled, the programs would auto-run and would be allowed to produce at most 6 sheets of line-printer paper of output. If they didn't compile, then the first six pages of source code and error messages would go to the printer instead. The following morning, someone would collect our printouts and snail-mail them back to the school.

: If you had a compile error, you'd have to copy everything out onto fresh coding forms and re-submit it.

: When the "unofficial" project to teach programming to 14/15 year-olds ran low on cash, they switched to 2nd class mail in each direction. We did two programming classes a week but we'd be VERY lucky to get a turnaround time of less than a week. So the line on panel two: "To compile your code, you had to mail it to IBM, took 4-6 weeks"...isn't *that* much of an exaggeration! We mailed it to the regional computing center - and it rarely took more than 2 weeks...but what she says isn't very far from the truth!

: In practice, things never went smoothly. The keypunch operators didn't routinely type FORTRAN code - they mostly entered stuff like names and addresses, that are somewhat tolerant of typo's. If you were struck by a typo, you'd have to just resubmit the exact same coding forms and hope you didn't get a typo on the following week! Since it was only a 10 week course, you got VERY good at writing your coding forms up clearly, to NEVER forgetting to slash your zeroes and put serifs on your I's...making 100% sure your code would compile first time around was essential to getting anything to run. We quickly learned that using "I" as a loop variable was worse than (say) "COUNT" because it was more likely to get mis-typed as a '1'.

: I begged and pleaded to be allowed to do the same course for two years running but on the second year, the keypunch operators finally rebelled at the extra work we were giving them as our programs grew larger and more ambitious. So we were instructed to punch our own cards using a "hand punch" machine where you manually held down a "chord" of keys to punch raw binary into the cards. Get just one bit wrong, and you had to toss out the entire card and start again. It would take multiple hours to punch in even a very short program! Gone was the idea of using "COUNT" for a loop variable! The idea of commenting your code became simply ludicrous - so the teacher told us to write comments onto blank cards and stick them into the deck where needed!

: Because of that horrendous problem, the concept of "code-reuse" was important! If you could re-use some of the cards from a previous program, or '''''borrow''''' a subroutine from a friend (they'd want it back afterwards!), you'd save yourself a mountain of time! Decks of handy subroutines had value...you could exchange them for all sorts of playground "items-of-value" with the other geeks who did the class.

: I'm tempted to say that this taught me a lot about the art of programming and the importance of checking your code and writing for re-use...but I rather doubt it. When I finally got to my second year in college, I had access to a PDP-11/20 with DecTapes and a DecWriter terminal, that's about when I started to learn something useful...and in my final year, 1977 - I was finally granted access to the PDP-11/70, UNIX and a ADM 3a "glass teletype". I could really get to learning the craft that's still paying my mortgage 40 years later. [[User:SteveBaker|SteveBaker]] ([[User talk:SteveBaker|talk]]) 14:25, 4 November 2016 (UTC)

Is it just me, or is there a parallel between sending you code off to be compiled and sending your code off to an app store. In both cases a required part of the build is sending your code off to a private company for approval. [[User:Olleicua|Olleicua]] ([[User talk:Olleicua|talk]]) 15:28, 4 November 2016 (UTC)

You didn't have to ship the punch cards to a company, but you did have to put them into a queue to be processed, and if you did have a typo or other simple mistake, you'd have to wait to get the output before knowing (which could take days). Most of what she says actually makes sense, it's just not fully accurate. You use to have to manually collect your garbage (making sure you unallocated your memory). You often did have to mix code and assembly (thought not for comments, and would that be // or /* */ or # or...). She also follows computer storage history. So again, not accurate, but it makes sense. [[Special:Contributions/108.162.237.88|108.162.237.88]] 19:56, 4 November 2016 (UTC)

Punch cards did not actually use binary, but a position based coding. Each column (character) had 12 positions where a hole could be punched. Numbers were represented by one hole in the matching numbered row; letters by two holes, one in the upper three row, and one in the lower nine, giving 27 combinations; punctuation and symbols mostly used three holes. I learnt this punching FORTRAN into cards in 1968[[Special:Contributions/141.101.98.232|141.101.98.232]] 01:14, 5 November 2016 (UTC)

Is there a parallel here between real life and computing? Panel 3 is like the way people wait until their trashcan's full before throwing it out, and panel 2 could reference how you had to mail things to people in the 'old days' instead of texting them, which takes no time nowadays. So, she's using the things he knows were true in the past (such as texting not existing) to make ridiculous statements which sound believable to him. Not sure about the other panels though.
