Show HN: Hacker Typer [joke]

160 points by duiker101 16y ago

Ever wanted to type as fast as those amazing hackers in the movies? now you can! just write something. Yes, i was really bored. To change writing speed: javascript:writer.speed=10;

How is the code generated? Is is scraped from publicly-accessible repositories (e.g. on github), or is it somehow generated on demand?

  random code taken from github, i think it was clone of some kernel from linus.
  - hayeah 16y ago
    it would be cool if you do ngram analysis that generates code based on keystrokes
- sp332 16y ago
  Google says it's from the Linux kernel, http://ftp.kernel.org/pub/scm/linux/kernel/git/jejb/storage-tree/kernel/groups.c http://ftp.kernel.org/pub/scm/linux/kernel/git/jejb/storage-...

wow, he exactly duplicated my sentient EMACS setup! My job is jeopardize.

Wow, my typing speed has improved lately ...

  Where's the GUI?
  - schallis 16y ago
    You need Visual Basic for that http://www.youtube.com/watch?v=hkDD03yeLnU http://www.youtube.com/watch?v=hkDD03yeLnU

  and this code should be projected on the hacker's face somehow

Nice! My son loves to type random gibberish in a Vim window and now he is going to type "real" code!
- ludwigvan 16y ago
  How does one generate random data in a computer? Put a new cs student in front of a vim screen. (Not my joke, but can't find the original one at the moment, I guess I read it on twitter recently.)

struct group_info init_groups = { .usage = ATOMIC_INIT(2) }; Is this legal ANSI C? You can initialize structs using .field = value ? Or is something else going on here?

  http://lxr.free-electrons.com/source/kernel/groups.c http://lxr.free-electrons.com/source/kernel/groups.c this should be the file i used. seems correct that way.

  Yes, it's C99. http://publib.boulder.ibm.com/infocenter/lnxpcomp/v8v101/topic/com.ibm.xlcpp8l.doc/language/ref/designators.htm#designators http://publib.boulder.ibm.com/infocenter/lnxpcomp/v8v101/top...

  If by ANSI C you mean C89, then no. It was added in C99. I believe the feature is technically known as a "designated initializer". (http://www.open-std.org/jtc1/sc22/WG14/www/docs/n1256.pdf http://www.open-std.org/jtc1/sc22/WG14/www/docs/n1256.pdf section 6.7.8)

I loved this. Could you please specify a monospaced font? It just feels so wrong otherwise.
- duiker101 16y ago
  done!
  - tga 16y ago
    not done! the font is still my browser's beautiful Serif (not overridden)
    - duiker101 16y ago
      extreamly strange, a lot of things changed in the last 24hrs might i ask you what browser are you using? EDIT: you were correct, my mistke, too hurry, can you check now? Thanks

Awesome. Humour! Great post in this gray serious community. I bet people will start discussing the design pattern flaws.

There looks like a syntax error early on with the ternary operator: nblocks = nblocks ? : 1;
- brodd 16y ago
  that's actually valid C through a GCC extension: http://gcc.gnu.org/onlinedocs/gcc-4.5.0/gcc/Conditionals.html#Conditionals http://gcc.gnu.org/onlinedocs/gcc-4.5.0/gcc/Conditionals.htm...

Reminds me of good old hexdump -C < /dev/urandom | grep "ca fe"
- pavel_lishin 16y ago
  For awhile, I'd run hexdump -C < /dev/urandom | grep "c0 ff ee" as a fake screensaver if I walked away from the computer for awhile, but it seems to eat processor cycles like crazy. :/ http://i.imgur.com/bSkoX.png http://i.imgur.com/bSkoX.png

I'm not sure how, but I knew this was kernel code about halfway through the first function. It's strange, because I've never written any kernel code before. Is there any dead giveaway in the first function that says, "This is code from the kernel"?
- bxr 16y ago
  The things that stuck out to me were a kmalloc/kfree and a goto/label (which isn't the biggest giveaway, but the only C I've seen that used gotos and wasn't terrible code is the linux kernel, the goto is also used in the same style as they are in the kernel).

Is there any reason this shouldn't work on an iOS device? It's all Javascript. I just can't get my iPad to pop up a keyboard to start triggering keypress events.
- incredimike 16y ago
  This js simply binds an "KeyDown" event listener to the document. There are no actual input fields so an iOS device.. that's why you don't get a keyboard.
incredimike 16y ago
This is BS.. Hackers don't write comments!
