YouTube playlists of HaD entries.  Videos culled from entries with video link - some are not "contest entry" but just progress update, etc.  Split into four playlists because YouTube limits to 200 videos / playlist.

As noted by davedarko: "wow, so if every 445 put up a 2min video, this means 15hours of video material!"

14hrs, 50mins to be exact.

RoGeorge provided this insight:

"At the moment when the input data was sampled,
- there were 718 hackers with a total of 791 projects

- 1 hacker with 6 projects ( http://hackaday.io/hacker/636 )
- 3 hackers with 4 projects each
- 10 hackers with 3 projects each
- 39 hackers with 2 projects each
- 665 hackers with 1 project each"

This chart shows submissions over time.  Orange line indicates projects which met requirements, while blue displays all submitted projects (so, obviously, orange < blue).

The final 7 days accounts for over a quarter of both submissions and valid entries:

Submissions (final week) = 259

Submissions (all other weeks) = 533

Valid Entries (final week) = 120

Valid Entries (all other weeks) = 325

The busiest day was Aug. 20, with 75 submissions (27 valid), although the best day for validated entries was Aug. 19 at 38.  Incidentally this reveals a discrepancy between hackaday.io time and hackaday.com time: 51 further submissions (13 valid) arrived on Aug. 21, the day after the deadline : )

Project Log statistics - this chart shows the number of project logs per project.  Most people posted either 0 or 4.

Average number of logs per project: 4.284 logs

Average, 0 excluded: 5.693 logs

Average, 4+ only: 6.765 logs

Top three bloggers:

* http://hackaday.io/project/1279 (44 log entries),

* http://hackaday.io/project/964 (49 log entries), and

* http://hackaday.io/project/996 (57 log entries!)

Thanks to user rawe, who provided this awesome chart tracking daily image uploads to hackaday.io over the past few months, along with significant dates!

Since there are tags on projects, there can also be tag statistics!  (Excluding "thehackadayprize" here, as it was by far the most common tag).  Tag cloud from the list of valid entries.  You guys with completed projects are way ahead of the game.

Top 20 tags, with number of uses:

120 ARDUINO
47 ROBOT
39 RASPBERRY PI
30 WIRELESS
29 COMPLETED PROJECT
28 ARM
27 BLUETOOTH
21 WIFI
19 LED
19 HOME AUTOMATION
18 IOT
18 AVR
14 ANDROID
12 RADIO
12 MICROCONTROLLER
12 LINUX
12 CNC
11 SERVO
11 OPEN SOURCE
11 INTERNET OF THINGS

1,220 tags were used only once.  Some personal favorites...

"#SoMuchSpace", "Canada Eh?", "Cthulhu", "DidIMentionAwesome?", "Earl Grey Tea", "For the good of all of us" / "Except the ones who are dead", "Gizmo for You", "High Likelihood of Crashing", "Mind Control", "NOT Arduino", "Pee" / "Poo", "Purple Monkey Dishwasher", "SimpsonsDidIt", "Space Jellyfish", "SPAAAAACE", "SPAAAAAAAACE".

True to Hackaday spirit, only one person mentioned SAFETY.

A great misuse of the Google YouTube API and some PHP mangling, and we now have YouTube playlists of all the entries. I actually screwed it up on creation and included ineligible (no project log) entries too. Oops. Gonna try to remove those now.

Hey, check it out, I found a bug in Google's YouTube API!

It would be nice to see when the projects were actually submitted to THP. I'm guessing there was a massive spike in the last week or so.

Also--three digit HaD Prize project submissions unite!

  Are you sure? yes | no

RoGeorge wrote 08/21/2014 at 15:53 point
And only one project in the list has 2 digits

  Are you sure? yes | no

Just added stats for project logs, congrats on being the wordiest person on the site (?!)

Haha thanks Greg. I guess I have a tendency to share a lot about my current project. It's actually been pretty helpful; lots of great comments that saved me a ton of time.

Getting the video IDs from the entries. Start with this script:
--
#!/usr/bin/perl

open (FP, 'video_list.txt') or die $!;

while (my $entry = <FP>)
{
chomp $entry;
print STDERR "Opening entries/$entry...\n";
open (FP2, "entries/$entry") or die $!;

my $found_a_link = 0;

while (<FP2>)
{
if ($_ =~ m/(?:youtu\.be|youtube\.com)\/(?:embed\/)?(?:watch\?)?(?:v=)?([A-Z
a-z0-9_-]{11})/ig)
{
print $1 . "\n";
}
$found_a_link = 1;
}
close (FP2);

die "Failed to find link in entries/$entry\n" if (!$found_a_link);
}

==

There will be lots of duplicates, so
$ ./get_video_links.pl | sort | uniq > playlist.txt

  Are you sure? yes | no

davedarko wrote 08/21/2014 at 14:43 point
I think those should be logs..

Great!
I did myself a small statistic too, for the fun.

I know what you are wondering...
- No, I do not have access to the Had database.
- No, I did not hacked the HaD!
:o)

Just grabbed the text only (with CTRL+C/CTRL+V) from the HaD wabpage that lists all the official entries to TheHackadayPrize and put the text in a spreadsheet. Then, filtered the rows strting with text "by ", in order to select just the hackers names. Make a pivot table to extract a list with unique names and to count how many project submitted each hacker.

There were about 790 projects and about 760 hackers, I don't remember the numbers.
What I know for sure is that a lot of hackers submitted more then one project to the competition, the most number of project for one person being 6.

I don't have the table with me and I'm a little bit lazy to redo it. I'll post the exact numbers when I'll arrive home.

What strikes me is that the official submitted page is showing a number of about 700-800 projects, but if I'm opening the project page and select the tag TheHackadayPrize, the webpage says that there are about 500 projects only.

  Are you sure? yes | no

Greg Kennedy wrote 08/21/2014 at 14:42 point
Good idea on counting the number of different hackers! I'll have to add that as a statistic too.

Very interesting! I had been wondering about this recently. A histogram would be really nice (though you'd probably have to do this: https://www.xkcd.com/1162/ ).

Searching for video links:
$ grep -li 'youtube\.com\|youtu\.be\|youku\.com' * | wc -l
548

Counting project logs:
$ perl -ne 'print if ($_ =~ /View all (\d+) project logs/ && $1 > 3)' * | wc -l
480

Doing both at once:
Dump video list to file, then replay it on command line to count project logs:
$ perl -ne 'print if ($_ =~ /View all (\d+) project logs/ && $1 > 3)' `cat ../video_list.txt` | wc -l
445
