such hacking / very code / wow

Our monthly mid-week hack night comes around again, promising as much algorithm as you can fit into an evening, as much wifi as we can snarf, and as many languages as we can tackle without breaking out into syntaxriots.

As usual we're upstairs in the Crown & Anchor & the schedule is: 

18:00 - Doors open. Arrive, chat, order food. 
19:15 - Kickoff. Choose tonight's hack, form teams. 
19:30 - Hack, Hack, Hack! 
21:00 - Show & Tell.

I think the prize for last month goes to the JavaScript team that mapped out every pub in a square mile. Only time will tell what we come up with for August.

See you there!

    Anyone here have can help me with jsPlumb ?
    or JavaScript memory leak ?

    My code works but consumes about 800Mb to generate flowchart in browser containing 3000 divs. The page size is about 3.8 Mb
    so 800Mb memory size doesn't make any sense.

      After hours of banging my head against the wall, I did thorough analysis of the code using web dev tools in Chrome. The memory snapshot was particularly helpful. I temporarily solved the problem by drawing fewer divs. For each div, I have listeners and then I have additional divs to form endpoints and SVGs to connect those div and form a flowchart. No memory leak.! I found some awesome libraries that could be used for flowcharting.

      If I am not wrong Adobe CS6 is cloud based. I wonder how they are handling the User Interface ( memory management, etc ).

      Hm. And I put a bug in the algorithm, too. ("if (!visited.contains(key))­" is in the wrong place...)

      So I had to fiddle some more with it, as ever:

    There were a lot of "Happy Campers" there this month, including quite a few first timers. It was a fascinating evening, if ultimately rather fruitless for my team :-( Still a very enjoyable meetup.

    Hello. What I did yesterday was just went, saw and came back to home. I get some kind of motivation. Thank Zak and Oliver, the Javascript?Clojure? :) Team for hospitality. And thank you all the attendees.

    So did the JavaScript team actually write a web scraping tool in clojure and sell it before Scala finished compiling... Maybe I was dreaming

    Not assuming that there would be a second crown and anchor i ended up in another one in central london and will call it a day. See you another time!

    Work conspires once more to prevent me hacking in West London :(

    Due to a clash with another meetup event, I am unable to attend. Oh how I wish I could be in two places at once!

    August 13, 2014

    • Kris J.

      I know that feeling. See you again dude. :-)

    Hello. I am Sujeong.
    This is my first time here and this meetup.
    I wonder what is Hack night.
    Can I go? if then, what should I prepare for it?

    1 · August 12, 2014

    • Peter J.

      No prep work required - just bring along problem solving and coding skills. Maybe some ideas on coding problems we could all try - have a look back through the old meets to see what we've done.

      Thank you for reply. ^^

    Thanks for arranging as usual, Kris. Unfortunately, I'm not free most Wednesdays. Hope you all have fun though!

      Aw, that's a shame. Well, the day of the week keeps moving. I'll try to get the next one booked in for a non-Wednesday. :-)

      We must count ourselves lucky to live in a town with so many tech evenings. :-}
