            Getting the upper convex hull of a set of points in R
            Asked 2022-Apr-11 at 07:47

            I am trying to obtain the upper convex hull, in R, of a set of points relating to productivity data. I expect it to be a function with decreasing returns to scale, with the input being worker hours and output being a measure of work done. I would like the upper convex hull because this would allow me to get the efficiency frontier.

            I have searched and found the method chull in R, but this gives the set of points in the whole envelope and not just the upper hull points. Is there a way to automatically select the upper hull points in R?

            As an example, we can find the upper hull of a points generated in a circle

            First of all, RandomForestRegressor only accepts numerical values. So encoding your numerical values to categorical is not a solution because you are not going to be able to train you model.

            The way to deal with this type of problem is OneHotEncoder. This function will create one column for every value that you have in the specified feature.

            How can I have multiple targets/executables in a single Node.js repo?
            Asked 2022-Mar-15 at 04:54

            I have a React Native app built using TypeScript, and I would like to also develop a number of CLI tools to help developers and 'back office' folks, also using TypeScript. I would like these to live in the same monorepo.

            Based on advice from colleagues and my own research, I have tried doing this by creating a subfolder in the repo, and creating a second package.json (and all the other config files), and npm install-ing as if it were a completely separate project. It didn't take long for this to become a total mess, primarily with duplicate imports where one thing mysteriously seems to import modules from the other targets' node_modules, but also just remembering to re-npm install all the different subprojects before each commit, etc. It gets even more confusing with the TS build folders lying around; they're another place for people to import the wrong thing from. The confusion caused by this approach has been a significant drain on productivity, and it feels like there has to be a better way. So that's the question:

            What is the best practice for building multiple TS/Node targets (and by "targets", I don't mean ES6 vs ESNext, I mean in the C/C++ sense: multiple output "programs", so in this case I want it to both create the bundle necessary for my RN app, but then also generate a CLI executable.) that all share code with one another, from a single monorepo?

            Visual Studio 2022 version 17.1.0 Update - Floating Windows no longer merge together to form a tabbed layout
            Asked 2022-Mar-05 at 13:14

            This is doing my nut in!

            Simply updating VS 2022 to ver. 17.1.0 has broken the ability to drag the header of a floating window towards the header of another window and allow them to merge into one single floating window with a tabbed view layout.

            This has ruined my productivity in being able to have multiple files open between a multi monitor layout. Is anyone aware of a option/setting that might have been disabled from the update?

            The screenshot below shows where I would usually drag one floating window towards another an if i left go of the mouse in the right place, the two windows would usually snap tpgather into one window with multiple tabs:

            Edit: Futher observations conclude the latest VS 17.1.0 have changed the way we can group floating windows together.

            By default, my tabs are configured to display along the top, however the only way i can group together the windows is if i change the tab location from the TOP to the Side, but this changes the tab layout in the main IDE as well as floating windows, so it screws eveything up.

            Merging the windows together:

            Its just occured to me that the you can snap together the floating windows into a tabbed view by dragging one window with the mouse over the top of another window and then you see the following icon appear:

            If you then drag the window and move your mouse cursor over the center point of this icon set then it will in fact merge the two windows together into a tabbed view.

            R Iteration using while loop and if statement
            Asked 2022-Feb-18 at 10:14

            I am new to R and I have the following problem: I need to solve a numerical optimisation problem where I realocate one unit of labor input (V20) such that overall productivity difference increases. I have to iterate the process until it has converged. For this, the productivity difference (Diff20) in each row has to be equal after optimisation.

            My approach is to calculate the maximum and the minimum productivity differences (Diff_max, Diff_min) and shift one unit of labor input (V20) from the row with the highest productivity difference Diff_max (which represents a decrease in productivity as more labor input was needed for a certain level of output) to the row with the lowest productivity difference Diff_min (which represents an increase in productivity as less labor input was needed for a certain level of output).

            I tried to combine a while loop with the if condition for that row to be the Diff_max or Diff_min.

            Unfortunately, this does not work at all, so I cannot even offer a propper error message.

            Does anybody of you have an idea how to solve/ approach this problem? It would be really great if you could help me! Many thanks in advance!

            Running the code I noted two other things:

            1. By increasing the nominator for max values and decreasing it for min values it does not converge.
            2. At 0.1 the grid-size seems too large to converge, I made it smaller, so the minimal working example converges.

            How to perform git move in Visual Studio, instead of git delete and git add, when renaming, moving files in Solution Explorer?
            Asked 2021-Dec-22 at 06:18

            Context

            I often move, rename files in Visual Studio 2022. Rename is a standard refactoring practice. However when I rename a file in Solution Explorer, not git mv operation is performed, instead git delete and git add.

            This causes loosing the history of that particular file/class, which is a great loss in many cases.

            Question

            I can do the move operation leaving the IDE and using command line

            ...

            ANSWER

            Answered 2021-Dec-22 at 06:18
            First, let's clear-up some misconceptions...
            • A git commit is a snapshot of your entire repo at a given point-in-time.
            • A git commit is not a diff or changeset.
            • A git commit does not contain any file "rename" information.
            • And git itself does not log, monitor, record, or otherwise concern itself with files that are moved or renamed (...at the point of creating a commit).

            The above might be counter-intuitive, or even mind-blowing for some people (myself included, when I first learned this) because it's contrary to all major preceding source-control systems like SVN, TFS, CSV, Perforce (Prior to Helix) and others, because all of those systems do store diffs or changesets and it's fundamental to their models.

            Internally, git does use various forms of diffing and delta-compression, however those are intentionally hidden from the user as they're considered an implementation detail. This is because git's domain model is entirely built on the concept of atomic commits, which represent a snapshot state of the entire repo at a particular point-in-time. Also, uses your OS's low-level file-change-detection features to detect which specific files have been changed without needing to re-scan your entire working directory: on Linux/POSIX it uses lstat, on Windows (where lstat isn't available) it uses fscache. When git computes hashes of your repo it uses Merkel Tree structures to avoid having to constantly recompute the hash of every file in the repo.

            So how does git handle moved or renamed files? ...but my git GUI clearly shows a file rename, not a file delete+add or edit!
            • While git doesn't store information about file renames, it still is capable of heuristically detecting renamed files between any two git commits, as well as detecting files renamed/moved between your un-committed repo's working directory tree and your HEAD commit (aka "Compare with Unmodified").

            • For example:

              • Consider commit "snapshot 1" with 2 files: Foo.txt and Bar.txt.
              • Then you rename Foo.txt to Qux.txt (and make no other changes).
              • Then save that as a new commit ("snapshot 2").
              • If you ask git to diff "snapshot 1" with "snapshot 2" then git can see that Foo.txt was renamed to Qux.txt (and Bar.txt was unchanged) because the contents (and consequently the files' cryptographic hashes) are identical, therefore it infers that a file rename from Foo.txt to Qux.txt occurred.
                • Fun-fact: if you ask git to do the same diff, but use "snapshot 2" as the base commit and "snapshot 1" as the subsequent commit then git will show you that it detected a rename from Qux.txt back to Foo.txt.
            • However, if you do more than just rename or move a file between two commits, such as editing the file at the same time, then git may-or-may-not consider the file a new separate file instead of a renamed file.

              • This is not a bug, but a feature: this behaviour means that git can handle common file-system-level refactoring operations (like splitting files up) far better than file-centric source-control (like TFS and SVN) can, and you won't see refactor-related false renames either.
              • For example, consider a refactoring scenario where you would split a MultipleClasses.cs file containing multiple class definitions into separate .cs files, with one class per file. In this case there is no real "rename" being performed and git's diff would show you 1 file being deleted (MultipleClassesw.cs) at the same time as the new SingleClass1.cs, SingleClass2.cs, etc files are added.
                • I imagine that you wouldn't want it to be saved to source-control history as a rename from MultipleClasses.cs to SingleClass1.cs as it would in SVN or TFS if you allowed the first rename to be saved as a rename in SVN/TFS.
            • But, and as you can imagine, sometimes git's heuristics don't work and you need to prod it with --follow and/or --find-renames= (aka -M).

            • My personal preferred practice is to keep your filesystem-based and edit-code-files changes in separate git commits (so a commit contains only edited files, or only added+deleted files, or only split-up changes), that way you make it much, much easier for git's --follow heuristic to detect renames/moves.

              • (This does mean that I do need to temporarily rename files back when using VS' Refactor Rename functionality, fwiw, so I can make a commit with edited files but without any renamed files).
            What does any of this have to do with Visual Studio though?
            • Consider this scenario:

              • You have an existing git repo for a C# project with no pending changes (staged or otherwise). The project has a file located at Project/Foobar.cs containing class Foobar. The file is only about 1KB in size.
              • You then use Visual Studio's Refactor > Rename... feature to rename a class Foobar to class Barfoo.
                • Visual Studio will not-only rename class Foobar to class Barfoo and edit all occurrences of Foobar elsewhere in the project, but it will also rename Foobar.cs to Barfoo.cs.
                • In this example, the identifier Foobar only appears in the 1KB-sized Foobar.cs file two times (first in class Foobar, then again in the constructor definition Foobar() {}) so only 12 bytes (2 * 6 chars) are changed. In a 1KB file that's a 1% change (12 / 1024 == 0.0117 --> 1.17%).
                • git (and Visual Studio's built-in git GUI) only sees the last commit with Foobar.cs, and sees the current HEAD (with the uncommitted changes) has Barfoo.cs which is 1% different from Foobar.cs so it considers that a rename/move instead of a Delete+Add or an Edit, so Visual Studio's Solution Explorer will use the "Move/Rename" git status icon next to that file instead of the "File edited" or "New file" status icon.
                • However, if you make more substantial changes to Barfoo.cs (without committing yet) that exceed the default change % threshold of 50% then the Solution Explorer will start showing the "New file" icon instead of "Renamed/moved file" icon.
                  • And if you manually revert some of the changes to Barfoo.cs (again: without saving any commits yet) such that it slips below the 50% change threshold then VS's Solution Explorer will show the Rename icon again.
            • A neat thing about git not storing actual file renames/moves in commits is that it means that you can safely use git with any software, including any software that renames/moves files! Especially software that is not source-control aware.

              • Previously, with SVN and TFS, you needed to restrict yourself to software programs that had built-in support for whatever source-control system you were using (and handled renames itself) or software that supported MSSCCI (and so saved renames via MSSCCI), otherwise you had to use a separate SVN or TFS client to save/commit your file-renames (e.g. TortoiseSvn and Team Foundation Explorer, respectively). This was a tedious and error-prone process that I'm glad to see the end of.
            • Consequently, there is no need for Visual Studio (with or without git support baked-in) to inform git that a file was renamed/moved.

              • That's why there's no IDE support for it: because it simply isn't needed.
            • The fact that a git commit isn't a delta, but a snapshot, means you can far more easily reorder commits, and rebase entire branches with minimal pain. This is not something that was really possible at all in SVN or TFS.

              • (After-all, how can you meaningfully reorder a file rename operation?)
