For example, how to sort the output below by the values in "Column" in the psql shell itself? my_db=> \d auth_user Table "public.auth_user" Column ...
Short answer The HTML specification only addresses scroll position restoration behavior, so the main factors that influences where focus will land when navigating the browser history are: user ...
Just found the How Can I Combine Two or More QuerySets in a Django View? article by James W. that perfectly answers my question (and just learned that a "Django model query" is called a QuerySet). ...
I have to modify a legacy Django web application where there are 2 tables to store the same information using the same database structure, and the only difference is the names of the tables (and th...
As far as I can tell, it is in part determined by the HTML spec's History API1, specifically the value of history.scrollRestoration. Quoting the HTML spec's scroll restoration mode paragraph: ...
Asked How to implement map using the fish (>=>, Kleisli composition) operator in F#? a couple of hours ago, and r~~'s answer blew my mind: let map f = id >=> switch f It is perfect ...
I'm learning monadic composition through Scott Wlaschin's Railway-oriented Programming post. Oncebind, switch, and >=> functions are defined, he introduces map to show how to "turn a one-trac...
First, a reminder to future self (the figure RFC 3986, Section 3. Syntax Components complemented with Section 3.2. Authority): The following are two example URIs and their component parts: ...
I have to keep reminding myself that a Giraffe project plugs into the ASP.NET Core pipeline or is itself an ASP.NET Core application , so if I can't find answers to my questions in the Giraff...
Having some trouble with giraffe-template on Mac M1, so decided to set up a Giraffe project manually. Started following the Doing it manually section of the Giraffe README, but got stuck right away...
Based on what I know so far, there is no difference. Paket has been created more than 10 years ago to address (perceived?) shortcomings of NuGet. (Reading the .NET history made my head spin, and l...
Many older projects (i.e., older than 5 years) provide instructions to the Paket .NET dependency manager (e.g., Suave), so I started digging into it, got confused, then gave up for while because er...
For example, given a mergeErrors function where input is always a list of Error strings, let es = [ Error 1; Error 2; Error 3 ] let mergeErrors<'a> (errors: Result<'a,int> list) : R...
The F# language guide (see Signatures article) has a very sparse definition of what a "sealed" type is: Attribute Description [<Sealed>] For a type that has no abstract me...
Solved this by writing my own clone function: open System.Reflection let cloneCellStyle (cell: NPOI.XSSF.UserModel.XSSFCell) = let original = cell.CellStyle // printfn "ORIGINAL: %A"...
The answer provided in the How to set the cell color to a user defined value using NPOI from F#? thread solves the problem of how to set the right properties using F#, but it uses a new ICellStyle ...
I failed to notice that a cell's CellStyle property returns the generic ICellStyle, which has to be cast down to NPOI.XSSF.UserModel.XSSFCellStyle in order to gain access to the FillBackgroundXSSFC...
As far as I can tell (from F# at least), cell can only be colored using predefined NPOI.SS.UserModel.IndexedColors. From the available methods / properties, val it: ICellStyle = NPOI.XSSF.UserM...
Paraphrasing the F# language guide's let Bindings in Classes article: A let binding in a class creates a private field or function; to expose data or functions publicly, declare a property or a...
Taking the example from this Stackoverflow question: type Vector2D(dx : float, dy : float) = static let zero = Vector2D(0.0, 0.0) static let onex = Vector2D(1.0, 0.0) static let ...
box and unbox are operators documented in the F# Core API Reference; it tersely states that they box / unbox (respectively) a strongly typed value. box a returns value a "wrapped" in a .NET Sy...
The Null Values article in the F# Language Reference show an example that uses it, but it does not explain what it does exactly. You can use the following code to check if an arbitrary value is ...
Found this old article at the bottom of the search results to be the best explanation to date: (The longer version is here, SSL Handshake (Sun Java System Directory Server Enterprise Edition 6.0 R...
I have little to no idea what happens after a client obtains the server's certificate. It has to make sure that it (somehow) valid, but how?
0. State of the art (as 11/22/2023) The NPOI.SS.Formula.DataValidationEvaluator class seems to mirror Apache POI's DataValidationEvaluator class, but NPOI's version only implemented the IsType met...
