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.

shit, my number is not listed. Is just creating a project sufficient to be an entry? Or is there something else I have to do?

Are you sure? yes | no

There are a lot of other things you had to do. From a quick glance at your page, I noticed you missed:

- two more project logs (four were required)
- a "TheHackadayPrize" tag
- official entry into the contest!

I suggest you make your next project a time machine ;)

Are you sure? yes | no

RoGeorge wrote 08/21/2014 at 17:52

Seems like you missed the instructions for how to apply for TheHackadayPrize.

1. You should have tagged your project with the tag "TheHackadayPrize"
2. You should have submitted your project for the contest by pressing the button "Submit project to...". The button is in the left side of the page, under the project pictures.
3. You should have put in the videoclip "About" section (on your YouTube movie page) a link to your Hack A Day project.
4. You should have put a tag "TheHackadayPrize" on your YouTube movie page.
5. You should have put only one movie of maximum 2 minutes, not a playlist
6. You should have post at least 4 entries in your project log on HaD site.
7. You should have put a page or schematics with "System design" where to explain/draw the ideea from your project.

Anyway, congratulations for your project, i like it.

I don't think stack is well visited, the feedback line on the other hand is full of advices around that, as well as the blog was :(

Are you sure? yes | no

zakqwy wrote 08/21/2014 at 19:12

it'd be nice if Stack was a bit more prominent. or maybe used more by HaD folks, or something. could be a good system.

Are you sure? yes | no

davedarko wrote 08/21/2014 at 19:14

stack should be followable. off to the feedback page...

Where is the feedback page/line you speak of?

Are you sure? yes | no

davedarko wrote 08/21/2014 at 20:27

http://hackaday.io/project/37-Feedback---Hackaday-Projects It's a good place to drop questions, bugs and features. You can find the link in the drop down menu where your projects and profile is linked. On http://hackaday.io/prize there where details listed and the rules specified that.

is there a chart activity-over-time etc. available?

Are you sure? yes | no

Blecky wrote 08/21/2014 at 17:04

This would be easy to do for project creation, each page has a creation date. Go go gadget Greg!

Are you sure? yes | no

Greg Kennedy wrote 08/21/2014 at 19:18

Wish granted.

Are you sure? yes | no

rawe wrote 08/21/2014 at 22:34

just did one myself in the meantime based on the data available on the image bucket: http://static.hackaday.io/images/3067531408659943482.jpg

As this is "image uploads per day", it should correlate with overall "content creation per day".

Are you sure? yes | no

rawe wrote 08/21/2014 at 22:44

...ah and they just used up 0,028 ppm of their indexing range

Are you sure? yes | no

Greg Kennedy wrote 08/22/2014 at 01:53

Now that is a sweet chart! Added to the details. How did you get that data?

Are you sure? yes | no

rawe wrote 08/22/2014 at 12:12

1. get directory listing from image server as xml with bucket API
2. xml-kung-fu to get just the "last modified" attribute as text file
3. python datetime to timestamps, numpy histogram with (timestamp[last]-timestamp[first])/60*60*24 bins
4. convert bin names back to datetime, then to string, export as csv
5. create open office chart / notes added

Are you sure? yes | no

davedarko wrote 08/21/2014 at 16:43

wow, so if every 445 put up a 2min video, this means 15hours of video material!

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.

Are you sure? yes | no

Greg Kennedy wrote 08/21/2014 at 17:52

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

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 (?!)

Are you sure? yes | no

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.

Are you sure? yes | no

Greg Kennedy wrote 08/21/2014 at 14:40

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

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

Good idea on counting the number of different hackers! I'll have to add that as a statistic too.

Are you sure? yes | no

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/ ).

Greg Kennedy wrote 08/21/2014 at 14:13

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

Are you sure? yes | no

Greg Kennedy wrote 08/21/2014 at 13:46

* Pull the master list:
$ wget http://hackaday.io/submissions/prize/list
* Perl script to grep for project IDs:

open (FP, 'list') or die $!;

while ()
