On: Google Pixel Buds

[paulkoer]

I guess if both have the pixel buds then you don't necessarily need the phone?

I get that its not quite the smooth experience (yet?) that we want it to be but that we're approaching this previously unbelievable futuristic thing is amazing to me!

[paulkoer]

I second this. I used to think practicing gratitude was stupid, or at least not really worth my time. I have recently picked up stoicism and one key techniques seems to be "practicing negative visualization" - basically imagining how much worse of you could be. I found that once I really think through all the hardships that I could find myself in I appreciate my current situation much more and feel much happier.

Curiously, I think I also get more done now because I feel better, am in a better mood and spend less time anguishing about all the things which are not perfect or could somehow be better. It has also made me aware that many people do find themselves in various hardships and my appreciation for my situation has really grown again through this.

Stop being so hard on yourself and cut yourself some slack - if you're the perfectionist type (like me) it does a lot more harm than good!

If someone is wondering about the relationship between sum types (discriminated unions / case classes) and the visitor pattern, I've written about this here [1].

On: Sqlpp11 – A type safe SQL template library for C++

[paulkoer]

This is a really awesome library to generate typesafe sql queries right from the C++ source code. Example usage:

  auto res = db(select(foo.name, foo.hasFun)
                .from(foo)
                .where(foo.id > 17 and foo.name.like("%bar%")));

If you're writing SQL queries in C++ code check it out!

[boris → paulkoer]

You should show the definition of 'foo'. That's where things get ugly.

[enricosada → boris]

things usually get ugly with projection (one class = one select) or class reuse (mapping)

this is code -> sql string -> exec -> code (mapping results)

best approach (ihmo) is using:

sql string -> exec -> results

with type for input/output directly generated sql string (and check for types)

like F# sql type provider ( http://fsprojects.github.io/FSharp.Data.SqlClient/ )

    [<Literal>]
    let query = "
        SELECT TOP(@TopN) FirstName, LastName, SalesYTD 
        FROM Sales.vSalesPerson
        WHERE CountryRegionName = @regionName AND SalesYTD > @salesMoreThan 
        ORDER BY SalesYTD
    " 

    type SalesPersonQuery = SqlCommandProvider<query, connectionString>
    let cmd = new SalesPersonQuery()

    cmd.AsyncExecute(TopN = 3L, regionName = "United States", salesMoreThan = 1000000M) 
    |> Async.RunSynchronously

    //output
    //seq
    //    [("Pamela", "Ansman-Wolfe", 1352577.1325M);
    //     ("David", "Campbell", 1573012.9383M);
    //     ("Tete", "Mensa-Annan", 1576562.1966M)]

everything typed, but:

- without the need to define class for input / output

- without learn a new functions

- easy add database specific syntax

On: Ask HN: What makes an API good?

[paulkoer]

I highly recommend the following talk by Joshua Bloch: "How to design a good API and why it mattes" [1].

Key points:

- When in doubt, leave it out - you can never remove things from an API but always add to it.

- Write several clients of the API to get a good feel how its used. Three is usually enough, one is not.
