dirslashls··on Ask HN: Why are front end developers (esp React) in such high demand in 2022?
Would love to see any factual references about the trend. It's in my vested interested as a founder of sqlframes.com
dirslashls··on Show HN: DataLemur – Ace the SQL Interview!
Nice one. How do you decide the difficulty of each problem? One hard problem seemed easy using analytic functions while a medium problem felt hard as it required a self-join the realization of which is the harder part.
dirslashls··on Show HN: Generate QR-code as Tetris animations
Creative!
dirslashls··on Show HN: A JWST/Hubble deepfield comparison on a zoomable/pannable map interface
Nice. It would be good to have a way to reset to get back to the initial state after zooming/panning.
dirslashls··on Show HN: High performance custom element virtual scroller
Great!

How does this compare to react-virtualized (https://github.com/bvaughn/react-virtualized)? Does it handle tables (rendered with table elements and not div)? Does it support column virtual scrolling?

dirslashls··on Show HN: No-Code SQL Builder
Nice work and great use of React Flow.

What level of sophisticated queries can be created with it? For example, can it do "Top N and Other"? Which BTW, was recently added for SQL Frames ( https://sqlframes.com/docs/data_sets/top_n_other_sets )

Most of these visual SQL builders I have seen only tackle the basic level of SQL. I am interested in an advanced SQL builder myself to plug as a no-code SQL builder to front the SQL Frames API.

dirslashls··on Ask HN: Which project has a good interactive tutorials on its website?
Sorry, the correct link is https://sqlframes.com/docs/sql_frames/intro

I didn't find a way to edit my initial comment.

dirslashls··on Show HN: ipyvizzu – open-source animated charts in Jupyter Notebooks
The morphing of the charts looks great. I don't know how that works, but currently I am using eCharts to achieve similar effects.
dirslashls··on Ask HN: Which project has a good interactive tutorials on its website?
Not sure if your ask is only for open source. I got lucky that my product is JavaScript based and Docusaurus is a perfect way for me to have live interactive docs by using MDX and a wrapper react component. https://sqlframes.com/docs and a quick 5 minute tutorial at https://sqlframes.com/tutorial .
dirslashls··on PRQL – A proposal for a better SQL
Go to https://sqlframes.com/demo and in the code editor enter the following and execute (this example is taken from the first example on PRQL github page). It generates SQL, but it also computes and displays the results within the browser (though the data set below gives no results).

const employees = SQL.values([{ title: 'Developer', country: 'USA', salary: 120, payroll_tax: 20, healthcare_cost: 6 }]); employees.schemaName = 'employees'; const { groupBy, where: { gt, eq, and }, agg: { count, sum, avg } } = SQL; return employees.pdf(SQL.script('[salary]+[payroll_tax]').as('gross_salary'),SQL.script('[gross_salary]+[healthcare_cost]').as('gross_cost')) .fdf(and(gt('gross_cost',0),eq('country','USA'))) .gdf(groupBy('title','country') ,avg('salary').as('average_salary') ,sum('salary').as('sum_salary') ,avg('gross_salary').as('average_gross_salary') ,sum('gross_salary').as('sum_gross_salary') ,avg('gross_cost').as('average_gross_cost') ,sum('gross_cost').as('sum_gross_cost') ,count().as('count')) .having(gt('count',200)) .orderBy('sum_gross_cost');
