Q: Script to run "npm install" for all directories/subdirectories that have a package.json file

AR7So to give some context: I have a relatively large repo with package.json files scattered across it for a bunch of unrelated projects. I just needed a quick script to run npm install for each of them. It couldn't have any dependencies that required an npm install. I figured running npm install ...

@Hosch250 Python is actually pretty great for beginners (if they are starting from nothing of course), much easier learning curve due to the friendly syntax, allows to learn the principles that apply to all languages
 
Not if you really want to be Pythonic.
Pythonic Python is quite difficult because you rarely need a plain and simple loop over a collection.
It has a lot of functional-type things for working with lists.
 
You can write everything as simple loops though just the same as most languages
 
Yep, it just won't be "standard" for the language.
 
The Pythonic way, well that's good if they want to pursue Python further
 
I'm having the worst time with my alpha/beta pruning.
I already trashed the whole thing once.
 
2:37 AM
Starting out with Node.js would be shooting themselves in the foot
 
@Phrancis I'm not going to have them do that :)
 
They can start with vanilla JS and then move into Node later, if they really want to do web stuff
 
Actually, right now, I'm not even pruning the bloody nodes.
I'm just trying to swap the alpha/beta values correctly.
 
Once you know Python though it's easy to branch into another language, since a lot of the same principles apply, just with a different syntax
Starting with Java/C#, or C++ especially, can be pretty daunting I imagine
 
When you walk up the tree, the alpha value for the current node becomes the next node's beta value, unless the node is infinity, in which the beta always stays at positive infinity and the alpha at negative infinity.
OK, that makes more sense and is simpler than what I've been doing.
 
2:40 AM
I wish I understood that tree stuff better, I don't have very good CS general knowledge
 
Trees are easy.
type MoveTree = { Move :Move; Parent :Option<MoveTree>; Children :Option<List<MoveTree>> }
So, you have a value. That's the Move.
That value has a Parent value, unless it is a root, in which the parent is null.
It also has child values (perhaps a max number, perhaps an unlimited number, perhaps none).
TBH, while I am working in a tree, no level knows about its parent in the alpha/beta minimax stuff.
You write it recursively, so the parents know their children, but the children just worry about their kids and themselves.
 
I should try to find some exercises to learn trees in a language I'm familiar with
 
I learned my trees while working on RD.
Oh, I knew some of the stuff, but that's what really showed me how to do it.
 
Maybe.
I'd just go build a tree.
Build a tree and write a BFS and a DFS.

I got my minimax actually working.
I realized that before, it was scanning N levels deep, but just returning the value for the level 0!
Hmm, pruning doesn't work.
But it is still many, many times faster than before.

Hmm. That weakened it pretty badly.

Q: Yet Another Todo Api

RubberDuckSo, I've been on an adventure trying to learn NodeJs and put together a stack that I'd be happy to put into production if one day my team said to me "Let's build it in Node!". What we have here is your standard "Todo Webservice". Any and all feedback is appreciated, because I had never written mo...

 
@RubberDuck I've just started to learning node.js too ;-]
 
@t3chb0t it's kind of a PITA IMO.
I mean, fourteen packages to cobble together a stack I was happy with. Fourteen.
Node is all fun & games until you decide you want prod quality code.
 
@RubberDuck At least installing them should be pretty straight-forward
 
that's true, but I think pure node would be too low level, I'm trying to see the packages as namespaces in c# but there are so many packages to learn about, I've just started with express and express-handlebars
I wonder however how it is possible that there is no native or out-of-the-box package to connect to ms-sql-server, only some workarounds
 
1:15 PM
@skiwi that much is true.
 
I'm wanting to make a desktop app and I need to choose my language pretty much now... Was thinking about Java vs C#, but I'd much rather do the interface in HTML/CSS instead of JavaFX or WPF, any thoughts?
I need to interact with the filesystem etc. so therefore I thought Java or C# would be a good idea, though C++ would work but I think not the best pick, same for C
 
@t3chb0t I would use hbs instead of express-handlebars. It handles all the file loading/reading for you.
@skiwi aww man. I was just reading about some folks who hacked Selenium into WPF so they could use HTML/CSS for it... I'll see if I can find the project again.
I would say the other question is do you need it to run on non-windows machines.
Windows GUIs are still Windows GUIs, even with code on the scene.
 
Hmm it is to support Arena drafting in Hearthstone, and Hearthstone runs on Windows and macOS I think... not sure about macOS, but people got it to work on Linux via gamesonlinux package or something and Wine also worked
I think the Linux versions still emulate the Windows file system structure though regarding program files, appdata, etc.
Maybe it's a good time too to look into Xamarin, though I have no experience with it
One thing is that there's some packages available for Java that off-load some of the annoying work, but maybe they're available for C# too, all community-made of course
 
@skiwi it's called Positron. btburnett.com/2016/12/…
Xamarin is always an option I guess. I tend to forget that it exists.. lol
 
I'll need to see how Positron differs from Xamarin I think
 
1:25 PM
It's still WPF, so Windows only I'm guessing. It just lets you use HTML/CSS to create your views.

Exactly ^^
 
I don't know how widespread Cordova is, that might be worth a look.
Heck, you could do it in Unity.
That's pretty multi-platform and easy to do weird things on GUI level.
 
Unity is way too heavy :P
Hmm maybe I should target that new Windows 10 API to get it to show up in the Store if I actually plan on releasing it
 
Meh, it's not bad.
Releasing something in stores is always a PITA, I'd say get it to work first :P
 
Xamarin supports releases to UWP, I'd say it's a very good choice if you want to release a stand-alone application
Do you remember SpeedSim from OGame?
 
2:48 PM
I've seen Xamarin in action. It works pretty well, but I've heard some horror stories about maintaining it.

@EBrown what?! No! You in Cleveland?
Or Cinci?
 
Toledo
Well, ~1 hour west of Toledo, but not too far.
 
@skiwi management should not be selecting technologies. There may be reasons to veto tech (where am I going to find F# devs?!), but not to select them.
 
I only noticed it because I saw it on your LinkedIn profile (the city you worked in) and I thought "oh wow, that's not too far away."
 
@EBrown well... no shit . That's cool mate.

@RubberDuck The new company I applied on likes the fact that I have F# experience and told me that it was really awesome.

@EBrown Cool :) The company I'm in negotiation with liked that I have Clojure experience
 
Even though they need a C# .NET developer, they said that they use F# for a few things and it's a really strong hiring point, apparently.
They also have at least one Microsoft MVP working there as well.
 
@EBrown Jon Skeet?
 
Oh, I would like it too! But F# devs are hind to find, and more expensive.
 
@skiwi Not Google.

@skiwi He's in England.
@EBrown F# is .NET.

@EBrown are we connected on Linkd in?
 
@RubberDuck I enjoy F#, and you're not wrong about either of those.

I know...
 
And in different fields.
 
@skiwi Yes, I wouldn't be surprised if some of the better developers found a new job very fast.
 
You could be an Excel MVP, or a C# MVP or a Windows MVP.
 
I thought you were saying that he wasn't a Microsoft MVP when you said Not Google
 
@RubberDuck Yeah you are a 1st level connection for me.

@skiwi UWP is nice, but just different enough from WPF to be irritating.
 
In fact, I recently endorsed you for C#, Soft Dev, SQL and Databases.
@skiwi No I was saying Google isn't the company I'm applying to work for lol
 
@skiwi The company I now work for sometimes appears to think my HAM license is worth more than my degree.
 
@EBrown thanks! I'm oddly short on C# endorsements.
 
It shows intent.

@EBrown Aye.

@Mast I need one of those.
@RubberDuck Somehow I have 8 to your 4 lol
 
I'm too old young for this type of stuff
 
@EBrown Novice license isn't hard if you're not afraid of basic physics.
Full license takes some studying.

@Mast Yeah, I want to get the full license over here.
 
I endorsed @RubberDuck for C#, IIRC.
 
And @DanPantry apparently. :)
 
@RubberDuck I'm thinking about Xamarin.Forms with the views in C# instead of XAML (xamarin.com/forms - there's an example) and deploying it as UWP
 
@EBrown most folks who've endorsed me know me for my database skills. Which I've spent the past 2 years avoiding like the plague.
 
@RubberDuck Ah, I never really interacted with you on a database level. I can understand that from all the , and Access endorsements and such.

All I know is it's an MVC website project.

Well, time to go. Everyone have fun!
 
Ugh... I'm not a fan of "the test". So few get it right. I know I've yet to give one that went well.
 
Programming tests are fine, just don't see them as an exam. Learn something about the applicant.
But 4 hours, shhhh.
That's just overdoing it IMO.

Total PITA, but I know that all of my soon to be coworkers can TDD.
Took me 2 weeks of a little here and there.
So here's my opinion: either don't bother with coding tests at all, or make them terribly difficult.
Anything in between is a waste of time.

akucheckThe F# code below embodies the two specific questions I have. It is part of a working transformation utility, the entirety of which, including sample data, is in this gist: http://bit.ly/2i3kUwF. Generically, the task is: given a file of discrete records, compute a value for a subsequent record...

Q: A command-line utility to solve a system of linear equations

AstroblemeI was re-checking my answers for a Math paper on my laptop. I needed to verify my solution for a system of linear equations. Unfortunately, I found no quick way to do that. That's why I wrote a (hopefully) simple Python program (using NumPy) to do this job quickly. General comments on the code ar...

 
@EBrown Yep waiting to revive and kill the other for ammo is the strat for coop :D! In halo 2 coop legendary you can't do that though

@Marc-Andre You, evil genius
 
@skiwi I got all my test cases passing pretty quickly.
I can run through 8 levels in about 1-2 seconds.
And this is without any optimization other than the basic minimax with alpha/beta pruning algorithm.
I'm sure I could get it to about <1 sec if I did optimize it.
And I still haven't done multithreading or caching :)
 
@Hosch250 Nice!
 
It knows how to do sacrifices for multi-jumps or to force a win better than I do.
 
@Hosch250 That looks okay to me
@Hosch250 Ah yes, you do want to cache moves at some point
I did something smart in my implementation, but I cannot remember it right now
 
@skiwi The only thing with that is that the cache gets invalidated so fast.
Every single move, the cached values don't look as deep.
Although, I could look into a few best-case moves and search them deeper.

Have you implemented a time limit restriction though?
 
No.
It thinks as long as it needs to.
 
That can be pretty long I guess :P
 
Close to a minute now, for a depth-10 move.
 
@skiwi Yeah just a touch of evil!
 
@Hosch250 My wife would disagree, but that's getting way off-topic.
Blanket statements are the root of all evil.

Q: Required parameters in JavaScript

GothdoECMAScript 6 introduced default parameters. The default value can be any expression, so you can use it to make a function throw an error when a parameter is not supplied: const mandatory = (name) => { throw new Error(`The ${name} parameter is mandatory`); }; const foo = (bar = mandatory('...

 
That, and arrays that aren't 0-indexed.

I just updated my minimax algorithm to one that really does work.

Q: Is something fishy in this code?

user6490375I have written the below code to invert a binary tree. Thus if the original tree is: Then the tree returned should be: /** * Definition for a binary tree node. * struct TreeNode { * int val; * TreeNode *left; * TreeNode *right; * TreeNode(int x) : val(x), left(NULL),...

Q: Tic Tac Toe game tree generator minimax

neoflashI have coded a working Tic Tac Toe game tree generator. It doesn't only generate the game tree, it also applies minimax values to each node. The code works fine on a board that already has 2 or more played moves but slows down significantly for an empty board. I'm thinking of implementing alpha-b...

@Hosch250 Piece.cs should have FS extension I think, otherwise looking good!
 
If the code is working and there are no exceptions might I suggest trying this question on code reviewNkosi 51 secs ago

Keep an eye on this question. Author has tried 2 times to remove or change the code in his question after receiving answers. He either has to stop doing that or contact a moderator.
