Introduction

[[!template text="""Welcome everybody. My name is Daniel Molina""" start="00:00:01.360" video="mainVideo-table" id="subtitle"]]

[[!template text="""&quot;Who needs Excel? Managing your students' qualifications""" start="00:00:05.061" video="mainVideo-table" id="subtitle"]]

[[!template text="""I'm a professor. I work every day.""" start="00:00:08.960" video="mainVideo-table" id="subtitle"]]
[[!template text="""I have to qualify my students.""" start="00:00:10.560" video="mainVideo-table" id="subtitle"]]
[[!template text="""While most would consider normal in this situation,""" start="00:00:12.520" video="mainVideo-table" id="subtitle"]]
[[!template text="""would be to use Excel or LibreOffice""" start="00:00:15.080" video="mainVideo-table" id="subtitle"]]
[[!template text="""for doing that.""" start="00:00:17.720" video="mainVideo-table" id="subtitle"]]
[[!template text="""However, I think that approaching it from Emacs""" start="00:00:18.600" video="mainVideo-table" id="subtitle"]]
[[!template text="""has several interesting advantages.""" start="00:00:21.180" video="mainVideo-table" id="subtitle"]]
[[!template text="""First, I would like to write the qualification""" start="00:00:24.480" video="mainVideo-table" id="subtitle"]]
[[!template text="""next to the justification, next to the student error,""" start="00:00:27.660" video="mainVideo-table" id="subtitle"]]
[[!template text="""and in the Excel format, it's not comfortable to do that.""" start="00:00:33.600" video="mainVideo-table" id="subtitle"]]
[[!template text="""Actually, I always prefer to write in Emacs""" start="00:00:36.640" video="mainVideo-table" id="subtitle"]]
[[!template text="""for many reasons, as many of you.""" start="00:00:38.840" video="mainVideo-table" id="subtitle"]]
[[!template text="""Also, I love text format because I can compare versions""" start="00:00:42.720" video="mainVideo-table" id="subtitle"]]
[[!template text="""using a control version system like Git and easily change.""" start="00:00:46.680" video="mainVideo-table" id="subtitle"]]
[[!template text="""This is very useful for the revision period""" start="00:00:50.280" video="mainVideo-table" id="subtitle"]]
[[!template text="""in which a student visits me""" start="00:00:52.760" video="mainVideo-table" id="subtitle"]]
[[!template text="""and maybe I can change the qualification for any reason.""" start="00:00:55.480" video="mainVideo-table" id="subtitle"]]
[[!template text="""I also can export the results directly to PDF""" start="00:01:01.040" video="mainVideo-table" id="subtitle"]]
[[!template text="""to publish them in my online campus for the student.""" start="00:01:03.440" video="mainVideo-table" id="subtitle"]]
[[!template text="""I have many tools for doing that.""" start="00:01:08.680" video="mainVideo-table" id="subtitle"]]
[[!template text="""I already knew about Org-table formula.""" start="00:01:11.360" video="mainVideo-table" id="subtitle"]]
[[!template text="""I thought it was very cool and useful""" start="00:01:13.200" video="mainVideo-table" id="subtitle"]]
[[!template text="""to use Emacs for that,""" start="00:01:15.200" video="mainVideo-table" id="subtitle"]]
[[!template text="""and I have actually found a package `orgtbl-aggregate`""" start="00:01:16.160" video="mainVideo-table" id="subtitle"]]
[[!template text="""that seemed adequate for doing that.""" start="00:01:19.240" video="mainVideo-table" id="subtitle"]]
[[!template text="""Unfortunately, I didn't see a lot of information""" start="00:01:22.860" video="mainVideo-table" id="subtitle"]]
[[!template text="""about how to do that in a painless way.""" start="00:01:26.320" video="mainVideo-table" id="subtitle"]]
[[!template text="""So, I have to learn, training and testing,""" start="00:01:29.160" video="mainVideo-table" id="subtitle"]]
[[!template text="""and then prepare these tools to solve that problem""" start="00:01:31.760" video="mainVideo-table" id="subtitle"]]
[[!template text="""and to help other teachers.""" start="00:01:35.000" video="mainVideo-table" id="subtitle"]]
[[!template text="""Anyway, it could be used not only for teaching""" start="00:01:36.640" video="mainVideo-table" id="subtitle"]]
[[!template text="""but for more contexts.""" start="00:01:39.960" video="mainVideo-table" id="subtitle"]]

Demonstration

[[!template text="""Well, let's start.""" start="00:01:41.960" video="mainVideo-table" id="subtitle"]]
[[!template text="""First, I have two sections,""" start="00:01:44.800" video="mainVideo-table" id="subtitle"]]
[[!template text="""the comments and the section of the table, or results.""" start="00:01:46.460" video="mainVideo-table" id="subtitle"]]
[[!template text="""I have... The comment for each student""" start="00:01:53.400" video="mainVideo-table" id="subtitle"]]
[[!template text="""is in a different headline.""" start="00:01:56.480" video="mainVideo-table" id="subtitle"]]
[[!template text="""It's very useful to check with a note.""" start="00:01:57.560" video="mainVideo-table" id="subtitle"]]
[[!template text="""I can go directly using your helm or ivy""" start="00:02:05.440" video="mainVideo-table" id="subtitle"]]
[[!template text="""or consult to go directly to the section.""" start="00:02:10.160" video="mainVideo-table" id="subtitle"]]
[[!template text="""So it's very nice.""" start="00:02:13.000" video="mainVideo-table" id="subtitle"]]
[[!template text="""Then I put the comment, right, completely wrong,""" start="00:02:14.560" video="mainVideo-table" id="subtitle"]]
[[!template text="""it answers other questions.""" start="00:02:22.880" video="mainVideo-table" id="subtitle"]]
[[!template text="""I put other comments here that I could send to the student,""" start="00:02:30.600" video="mainVideo-table" id="subtitle"]]
[[!template text="""you can imagine, and then""" start="00:02:35.840" video="mainVideo-table" id="subtitle"]]
[[!template text="""I can put the qualification, the score for each student.""" start="00:02:37.481" video="mainVideo-table" id="subtitle"]]
[[!template text="""The thing with that is, initially,""" start="00:02:40.160" video="mainVideo-table" id="subtitle"]]
[[!template text="""when I started doing that, I put, I don't know,""" start="00:02:43.160" video="mainVideo-table" id="subtitle"]]
[[!template text="""the exception and a qualification with that.""" start="00:02:46.220" video="mainVideo-table" id="subtitle"]]
[[!template text="""Okay, that's one point, this a three,""" start="00:02:50.720" video="mainVideo-table" id="subtitle"]]
[[!template text="""and use a column total with something like that.""" start="00:02:55.680" video="mainVideo-table" id="subtitle"]]
[[!template text="""Okay, that's nice.""" start="00:03:06.680" video="mainVideo-table" id="subtitle"]]

Range

[[!template text="""But then, when I started getting more and more parts,""" start="00:03:08.320" video="mainVideo-table" id="subtitle"]]
[[!template text="""I considered it more useful to use,""" start="00:03:11.640" video="mainVideo-table" id="subtitle"]]
[[!template text="""to put for each part,""" start="00:03:17.082" video="mainVideo-table" id="subtitle"]]
[[!template text="""which is the maximum qualification,""" start="00:03:20.700" video="mainVideo-table" id="subtitle"]]
[[!template text="""on the range of the qualification.""" start="00:03:20.300" video="mainVideo-table" id="subtitle"]]
[[!template text="""In that case, I'm going to put,""" start="00:03:22.920" video="mainVideo-table" id="subtitle"]]
[[!template text="""the first one is two scores, the second three points,""" start="00:03:25.560" video="mainVideo-table" id="subtitle"]]
[[!template text="""the third one is one point, and the last one, four points.""" start="00:03:28.680" video="mainVideo-table" id="subtitle"]]
[[!template text="""And instead of putting that in that way,""" start="00:03:35.000" video="mainVideo-table" id="subtitle"]]
[[!template text="""I like to put one is completely right,""" start="00:03:37.800" video="mainVideo-table" id="subtitle"]]
[[!template text="""zero is completely wrong, or maybe some intermediate values for that.""" start="00:03:41.028" video="mainVideo-table" id="subtitle"]]
[[!template text="""Of course, I have to change the qualification,""" start="00:03:47.320" video="mainVideo-table" id="subtitle"]]
[[!template text="""the formula, so it's very simple.""" start="00:03:51.000" video="mainVideo-table" id="subtitle"]]
[[!template text="""I only have to put,""" start="00:03:54.440" video="mainVideo-table" id="subtitle"]]
[[!template text="""multiply the values of the second line with that.""" start="00:03:56.480" video="mainVideo-table" id="subtitle"]]
[[!template text="""So, it's very useful for doing that.""" start="00:04:08.300" video="mainVideo-table" id="subtitle"]]

More qualifications

[[!template text="""Okay, that's the first part, so I can put the comment,""" start="00:04:11.900" video="mainVideo-table" id="subtitle"]]
[[!template text="""I can go to the section, I can create...""" start="00:04:16.640" video="mainVideo-table" id="subtitle"]]
[[!template text="""I'm going to put more qualifications.""" start="00:04:19.960" video="mainVideo-table" id="subtitle"]]
[[!template text="""Now I'm going to put the table.""" start="00:04:24.920" video="mainVideo-table" id="subtitle"]]
[[!template text="""First I'm going to change, rename the column name,""" start="00:04:27.640" video="mainVideo-table" id="subtitle"]]
[[!template text="""because it's easier when there is only one word.""" start="00:04:30.460" video="mainVideo-table" id="subtitle"]]
[[!template text="""And it's very simple to use. You only have to put""" start="00:04:39.040" video="mainVideo-table" id="subtitle"]]
[[!template text="""the name, aggregate, the name of the table,""" start="00:04:47.160" video="mainVideo-table" id="subtitle"]]
[[!template text="""in that case group A,""" start="00:04:51.440" video="mainVideo-table" id="subtitle"]]
[[!template text="""and in another string, the columns.""" start="00:04:54.660" video="mainVideo-table" id="subtitle"]]
[[!template text="""For instance, name, surname, total.""" start="00:04:57.200" video="mainVideo-table" id="subtitle"]]
[[!template text="""And you can see that you can get a lesson list""" start="00:05:03.800" video="mainVideo-table" id="subtitle"]]
[[!template text="""with all the students,""" start="00:05:07.440" video="mainVideo-table" id="subtitle"]]
[[!template text="""but only with the final score to publish them.""" start="00:05:09.120" video="mainVideo-table" id="subtitle"]]
[[!template text="""Okay?""" start="00:05:16.760" video="mainVideo-table" id="subtitle"]]
[[!template text="""Even you can update the name of the column,""" start="00:05:17.680" video="mainVideo-table" id="subtitle"]]
[[!template text="""not in the original table,""" start="00:05:20.680" video="mainVideo-table" id="subtitle"]]
[[!template text="""but in the lesson table using that format.""" start="00:05:21.801" video="mainVideo-table" id="subtitle"]]
[[!template text="""Okay?""" start="00:05:29.560" video="mainVideo-table" id="subtitle"]]
[[!template text="""That is a good option.""" start="00:05:32.100" video="mainVideo-table" id="subtitle"]]

Subsets

[[!template text="""Now we are going to see how can we use that""" start="00:05:34.240" video="mainVideo-table" id="subtitle"]]
[[!template text="""to make a subset of the students.""" start="00:05:38.500" video="mainVideo-table" id="subtitle"]]
[[!template text="""For instance, imagine, this is me,""" start="00:05:44.360" video="mainVideo-table" id="subtitle"]]
[[!template text="""I'm going to put the bad, I change, now I can update,""" start="00:05:47.840" video="mainVideo-table" id="subtitle"]]
[[!template text="""you can see this, but also I'm going to put a list""" start="00:05:54.800" video="mainVideo-table" id="subtitle"]]
[[!template text="""with the students that have failed the exam.""" start="00:06:02.760" video="mainVideo-table" id="subtitle"]]
[[!template text="""It's simple, because this package has the option `:cond`.""" start="00:06:10.961" video="mainVideo-table" id="subtitle"]]
[[!template text="""I'm going to put first to see it better,""" start="00:06:21.260" video="mainVideo-table" id="subtitle"]]
[[!template text="""I'm going to put a condition""" start="00:06:26.200" video="mainVideo-table" id="subtitle"]]
[[!template text="""in which we aggregate less than a half, 5,""" start="00:06:28.600" video="mainVideo-table" id="subtitle"]]
[[!template text="""and I have to use a `string-to-number` total.""" start="00:06:37.520" video="mainVideo-table" id="subtitle"]]
[[!template text="""In that way, I can see that this is the student""" start="00:06:44.180" video="mainVideo-table" id="subtitle"]]
[[!template text="""that has failed the exam,""" start="00:06:47.260" video="mainVideo-table" id="subtitle"]]
[[!template text="""I could use that to make another table,""" start="00:06:48.840" video="mainVideo-table" id="subtitle"]]
[[!template text="""this is the people that passed the exam.""" start="00:06:54.080" video="mainVideo-table" id="subtitle"]]

Sorting

[[!template text="""Another interesting feature is that""" start="00:07:08.300" video="mainVideo-table" id="subtitle"]]
[[!template text="""I can... the lesson table can be sorted automatically.""" start="00:07:10.981" video="mainVideo-table" id="subtitle"]]
[[!template text="""It's simple. You only have to put this symbol (`^`),""" start="00:07:15.621" video="mainVideo-table" id="subtitle"]]
[[!template text="""and you can put next to the column you want""" start="00:07:20.101" video="mainVideo-table" id="subtitle"]]
[[!template text="""to use for the sort, and then you can put""" start="00:07:23.361" video="mainVideo-table" id="subtitle"]]
[[!template text="""`a` if you want to sort alphabetically,""" start="00:07:27.000" video="mainVideo-table" id="subtitle"]]
[[!template text="""in uppercase if you want to reverse the sort,""" start="00:07:30.680" video="mainVideo-table" id="subtitle"]]
[[!template text="""and `n` if you want to sort numerically.""" start="00:07:33.880" video="mainVideo-table" id="subtitle"]]
[[!template text="""For instance, I can put that""" start="00:07:38.920" video="mainVideo-table" id="subtitle"]]
[[!template text="""from the lesser score to the best score,""" start="00:07:40.760" video="mainVideo-table" id="subtitle"]]
[[!template text="""or here from the best score to the lesser score.""" start="00:07:43.960" video="mainVideo-table" id="subtitle"]]
[[!template text="""And this sort is completely independent""" start="00:07:46.640" video="mainVideo-table" id="subtitle"]]
[[!template text="""to the sort of the original table.""" start="00:07:48.961" video="mainVideo-table" id="subtitle"]]

New table

[[!template text="""the number of passed students, failed students""" start="00:08:09.640" video="mainVideo-table" id="subtitle"]]

[[!template text="""I'm going to put the pass, in that case, as column,""" start="00:08:16.520" video="mainVideo-table" id="subtitle"]]
[[!template text="""I can put the count, of course, I can put the count,""" start="00:08:26.560" video="mainVideo-table" id="subtitle"]]
[[!template text="""the number of students""" start="00:08:32.920" video="mainVideo-table" id="subtitle"]]
[[!template text="""that have passed, so I'm going to put in that way, ok?""" start="00:08:35.800" video="mainVideo-table" id="subtitle"]]
[[!template text="""I'm going to put pass, count, failed, ratio.""" start="00:08:42.080" video="mainVideo-table" id="subtitle"]]
[[!template text="""You can see, ok?""" start="00:08:58.480" video="mainVideo-table" id="subtitle"]]
[[!template text="""But this only the count,""" start="00:08:59.740" video="mainVideo-table" id="subtitle"]]
[[!template text="""you are going to put the number wrong.""" start="00:09:01.860" video="mainVideo-table" id="subtitle"]]
[[!template text="""So, it's true, but you can actually put formula here.""" start="00:09:04.520" video="mainVideo-table" id="subtitle"]]
[[!template text="""For instance, you can say,""" start="00:09:08.360" video="mainVideo-table" id="subtitle"]]
[[!template text="""I know that I have 3 students,""" start="00:09:10.080" video="mainVideo-table" id="subtitle"]]

[[!template text="""the ratio of students.""" start="00:09:48.360" video="mainVideo-table" id="subtitle"]]

Combining
