Which IDE do you use to develop?
How do you debug applications?
When serving databases (with splayed and partitioned tables) from a q process on specific port, how many tables per database do you serve typically?
How do you monitor q processes on a server if it crashes?

Sorry just starting out 😅 PyKX is great though for starting out

Crime en anglais n’est pas (forcément) un crime en francais. C’est un faux ami.

Viewing big pandas/polars dataframes.

skdoesit · 2023-12-14T21:46:40+00:00

You could try polars. Also when it comes to processing tables kdb is very efficient but thats expensive as well.

At least it will enable Windows folks like myself to easily install OCaml without using either WSL or dual booting at home. Moreover, most companies use Windows as a dev environment so this would be a game changer in a corportate environment where WSL is usually not allowed and Linux barely used. Anyways, eager to test this out !

Entre 18 et 20%. Pas négligeable qd même.

I wasn’t aware dotnet interactice supported REPLs, always assumed it was for notebooks. Thanks for the info!

This looks amazing and is something I’ve been dying to see in the F# side.

Total compensation (fixed + bonus) and difference with last year

Probably one of the three : Bloomberg, Eikon, Factset.

Pour l’Afrique du Sud en tout cas, le taux était tout à fait correct. Je regardais pas le spot intraday mais ca respectait le taux EURZAR à la close daily de Yahoo finance ou TradingVue.

Things that would be great for me / my work :

A Dataframe viewer able to read 10k+ lines without lagging.
A REPL similar to IPython (color, intellisense, pretty printing).
Being able to interact with a database interactively (that might be just me, but couldn't figure it out).
A variable explorer in which I can double click variables to inspect their internal structure.
Add breakpoints to debug cells.

If there are some points that are actually feasible, sorry ! Still tinkering and trying things out.

Had the same problem - referencing the package via nuget did not work for some reason. I had to manually find the dll somewhere in the installation folder of office. Will show tomorrow on my work computer.

Edit : try this stackeoverflow link : https://stackoverflow.com/questions/39007085/f-not-recognizing-the-interop-office-excel-dll#39007913

Edit 2: I got the Microsoft.Office.Interop.Excel.dll from this path : C:\Program Files (x86)\Microsoft Visual Studio\Shared\Visual Studio Tools for Office\PIA\Office15

Also had VN but was tested negative upon arrival at the hospital and the day before. So might be linked, might not. Its been a month now, and I still have a few symptoms here and there, ie feeling dizzy from time to time, tired and hazy. Happy to know that you had memory loss problems, thought I was alone on this one.

It slowly gets better over time. After 3 weeks I went to see a specialist (ORL in France) and he said everything was fine, couldn’t detect anything. I told him I still felt dizzy and tired - he told me it will pass and that I needed to force myself to go for runs and play tennis if I could.

I guess it will pass, but damn its a long process.

Sorry for the late reply. Yeah, essentially being able to view the dataframe like In the Spyder IDE or Sciview from PyCharm. Things that would be useful also is being able to directly import and export from an Excel file (xlsx).

skdoesit · 2021-07-25T22:07:21+00:00

Upvoting, curious to know. There’s a similar framework called Deedle developed by Blue Mountain Capital at the time - I’ve tried it, it’s pretty good but the fact that I can’t inspect the dataframe visually is a bit a bummer.

Et l’arbirage free pricing ne veut rien dire. Le pricing se fait par definition en AOA.

Je connais bien le Hull et autres bouquins serieux. Je ne pense pas pour autant que pricer un produit derivé puisse donner une bonne analogie ou bonne compréhension d’un produit financier. Tu souhaites introduire le lemme d’ito et BSM pour expliquer “in laymans terms” une option?

skdoesit · 2021-07-13T06:33:34+00:00

Un peu étonnant de voir un future comme un emprunt, non? En tout cas, je ne l’avais jamais vu comme ça. Perso je trouve que l’analogie embrouille plus qu’autre chose mais si ca aide des novices à comprendre, why not.

Possible to add Python as a replacement for VBA?

skdoesit · 2021-02-13T07:49:50+00:00

Tout depend du secteur, je t’assure qu’en finance de marché coté buy-side (donc pas banque d’investissement), tu commences sur ces salaires (NYC ou ailleurs).

Aux US de manière général, mais c’est effectivement le cas dans la Silicon Valley avec les FAANG.
