            MySql 5.5; possible to exclude a table from logging?
            Asked 2022-Mar-30 at 04:10

            MySql 5.5 has a few logging option, among which the "Binary Logfile" with Binlog options which I do not want to use and the "query log file" which I want to use.

            However, 1 program using 1 table in that database is filling this logfile with 50+Mb per day, so I would like that table to be excluded from this log.

            Is that possible, or is the only way to install another MySql version and then to move this 1 table?

            Thanks, Alex

            There are options for filtering the binlog by table, but not the query logs.

            There are no options for filtering the general query log. It is either enabled for all queries, or else it's disabled.

            There are options for filtering the slow query log, but not by table. For example, to log only queries that take longer than N seconds, or queries that don't use an index. Percona Server adds some options to filter the slow query log based on sampling.

            You can use a session variable to disable either slow query or general query logging for queries run in a given session. This is a dynamic setting, so you can change it at will. But you would need to change your client code to do this every time you query that specific table.

            Another option is to implement log rotation for the slow query log, so it never grows too large. See https://www.percona.com/blog/2013/04/18/rotating-mysql-slow-logs-safely/

            Answered 2022-Mar-17 at 11:33

            MongoDB Compass has known issues on exporting an importing data for long time and it seems they are not willing to improve it!

            When you try to export data using compass, it uses some sample documents to select the fields and if you are unlucky enough, you will miss some fields.

            SOLUTION:

            1. Use the Mongo DB Compass Aggregation tab to find all the existing fields in all documents:

              [{$project: { arrayofkeyvalue: { $objectToArray: '$$ROOT'} }},
              {$unwind: '$arrayofkeyvalue'},
              {$group: { _id: null, allkeys: { $addToSet: '$arrayofkeyvalue.k' } }}]

            2. Add the fields from the 1st step to the Export Full Collection (Select Fields).

            3. Export it!

            How to improve the HTML Table Styling that is to be converted into a PDF File
            Asked 2022-Jan-25 at 00:43

            I have a Python code that is creating HTML Tables and then turning it into a PDF file. This is the output that I am currently getting

            This image is taken from PDF File that is being generated as result (and it is zoomed out at 55%)

            I want to make this look better. Something similar to this, if I may

            This image has 13 columns, I don't want that. I want to keep 5 columns but my major concern is the size of the td in my HTML files. It is too small in width and that is why, the text is also very stacked up in each td. But if you look at the other image, text is much more visible and boxes are much more bigger width wise. Moreover, it doesn't suffer from height problems either (the height of the box is in such a way that it covers the whole of the PDF Page and all the tds don't look like stretched down)

            I have tried to play around the height and width of my td in the HTML File, but unfortunately, nothing really seemed to work for me.

            Edit: Using the code provided by onkar ruikar, I was able to achieve very good results. However, it created the same problem that I was facing previously. The question was asked here: Horizontally merge and divide cells in an HTML Table for Timetable based on the Data in Python File

            What I've done here is remove the borders from the table and collapsed the space for them.

            I've then used more semantic elements for both table headings and your actual content with semantic class names. This included adding a new element for the elements you want at the bottom of the cell. Finally, the teacher and codes are floated left and right respectively.

            Please note this question is an extension of this previously asked question: How to make Images/PDF of Timetable using Python

            I am working on a program that generates randomized Timetable based on an algorithm. For the Final Output of that program, I require a Timetable to be stored in a PDF File.

            There are multiple sections and each section must have its own timetable/schedule. Each Section can have multiple Courses whose lectures will be allocated on different slots from Monday to Friday by the algorithm. For my timetable,

            • There are 5 days in total (Monday to Friday)
            • Each day will have 5 slots (0 to 4 in indexes. With a "Lunch" Break between 3rd and 4th slot)

            As an Example, I have created below a dictionary where key represents the Section and the items have a 2D Array of size 5x5. Each Index of that 2D array contains the course details for which the lecture will take place in that slot.

            I am not much familiar with Jinja, so this answer might not be the most efficient one.

            By using basic hard coding in your Template.HTML file, I was able to achieve the results you are trying to. For this, I used the same code that was given by D-E-N in your previous question.

            I combined all the attributes of your object into a string

            • An attribute is differentiated from another with @ (like Course and Teacher)
            • Instead of using space character, I used a _ character to represent space character in the attributes.
            • If one slot contains multiple objects, they are differentiated with space character (just like in the code provided by D-E-N)

            App Service runs your apps in a sandbox and most PDF libraries will fail. Looking at the IronPDF documentation, they say that you can run it in a VM or a container. Since you already are using App Service, simply package your app in a container, publish it to a container registry and configure App Service to run it.

            2. How do I use melt?

            3. When do I use melt?

            Answered 2021-Nov-04 at 09:34
            Note for users with pandas version under < 0.20.0, I will be using df.melt(...) for my examples, but your version would be too low for df.melt, you would need to use pd.melt(df, ...) instead. Documentation references:

            Most of the solutions here would be used with melt, so to know the method melt, see the documentaion explanation

            Unpivot a DataFrame from wide to long format, optionally leaving identifiers set.

            This function is useful to massage a DataFrame into a format where one or more columns are identifier variables (id_vars), while all other columns, considered measured variables (value_vars), are “unpivoted” to the row axis, leaving just two non-identifier columns, ‘variable’ and ‘value’.

            And the parameters are:

            Parameters

            • id_vars : tuple, list, or ndarray, optional

              Column(s) to use as identifier variables.

            • value_vars : tuple, list, or ndarray, optional

              Column(s) to unpivot. If not specified, uses all columns that are not set as id_vars.

            • var_name : scalar

              Name to use for the ‘variable’ column. If None it uses frame.columns.name or ‘variable’.

            • value_name : scalar, default ‘value’

              Name to use for the ‘value’ column.

            • col_level : int or str, optional

              If columns are a MultiIndex then use this level to melt.

            • ignore_index : bool, default True

              If True, original index is ignored. If False, the original index is retained. Index labels will be repeated as necessary.

              New in version 1.1.0.

            Logic to melting:

            Melting merges multiple columns and converts the dataframe from wide to long, for the solution to Problem 1 (see below), the steps are:

            1. First we got the original dataframe.

            2. Then the melt firstly merges the Math and English columns and makes the dataframe replicated (longer).

            3. Then finally adds the column Subject which is the subject of the Grades columns value respectively.

            This is the simple logic to what the melt function does.

            Solutions:

            I will solve my own questions.

            Problem 1:

            Problem 1 could be solve using pd.DataFrame.melt with the following code:
