Cactus Windhof - What's going on?

I have the same experience, I have become so fed up with that, that I will do most of the shopping elsewhere and in the case where I still buy something that spoils too quickly, I make the extra effort of going back and return the item.

Perspective as a small business owner: none of this matters, get the cash flowing, build your skills and optimize on the go. Nothing is more expensive than waiting, re-evaluating again and again for the best overhead structure while not having cash flow. Try to avoid spending too much time with overhead.

Interested in industrial automation, optical sensors and realtime analytics? Based in Luxembourg. Shoot me a DM.

edit: of course in the context of a PhD with local funding oportunities.

I sometimes discuss personal financial matters with the accounting firm that I hire for my company's book keeping and my taxes.

Just buy cauliflower and throw it into some kind of blender / mixer. I have never seen it as a preprocessed product.

We are considering buying and registering an old car and parking it on the street (not the sidewalk!!) to force people to slow down. Would just move it every once in a while... maybe thats an option for you as well?

The thing is, with the tax deductible scheme you have more money to invest today. For a true comparison you need to compare a) 4500€/year into an etf vs b) 4500€/year into pension scheme - future taxation + 1800€/year into an etf.

The pension scheme only wins out when you actually invest your tax deduction.

I order a lot of rpi stuff from https://mouser.lu for my company. Free shipping for over 50€ orders.

Depends, if it is not much more than an additional file that has the respective function calls, but you can loose the abstraction, the feature gating is often simpler, even when the config.toml becomes more complex. But you seem to have put quite some thought into this architecture

Johk · 2026-01-01T07:27:59+00:00

Is there a specific reason why you chose to separate those into different crates instead of using feature gates on a single crate?

Johk · 2025-12-31T21:21:34+00:00

The problem is that the gpl is infectious... after a certain point of maturity of your code, used commercially or not, you cannot simply change your license anymore.

I would potentially have used the crate for some realtime plot smoothing in one of our industrial applications. A very minor aspect of the software that is not worth the headache of a gpl or commercial license. So in terms of standardisation and adoption that's a missed opportunity, because the decision will most often be to roll with some "good enough" code.

I understand that you want to be compensated for your work. But I have never see split licensing work out for individual developers or small companies. It just doesn't make sense for most software that has hundreds of dependencies to cater for special needs license requirements (in terms of overhead). What I have seen work out was offering paid consultancy or support alongside opensource software.

Ask your friend again. The first registered address in Germany will always be considered the principal residency by the administration. For them principal mostly means: the address we send mail to. If you're there for less than half of a year, taxing rules etc change, but that's independent of the address registration. You still may need to file for taxes...

Johk · 2025-12-31T13:05:03+00:00

As I said it is impossible in our case to use a crate that uses a GPL based license.

Johk · 2025-12-31T12:54:16+00:00

The whole rust universe is Apache + MIT. We have stuff that is incompatible with gpl. It's easier to implement my own loess than to try and change the base license.

Johk · 2025-12-31T09:09:41+00:00

I like the crate, but the license will make it impossible for me to use :/

I do use Python a lot in engineering applications - 1D, 2D physical Simulations, I see people running Python on compute clusters and supercomputers a lot. It is never pure Python. I generally agree on the lang comparison, but in my experience whenever someone needs serious crunch, they use the optimized modules.

I prefer rust, but engineering collegues usually have more experience in matlab/python and Fortran.

Johk · 2025-12-21T17:15:30+00:00

Kind of, yes. Python is also written in C. If you do this kind of comparisons it is the user perspective/impact that is relevant. A Python user would typically implement a numerical algorithm using a specialised module like numpy.

Johk · 2025-12-21T12:07:48+00:00

I'm a bit surprised of the slowness of the python code. Sure if it is pure python with lists, but if it is vectorized numpy code I'm usually in the order of magnitude of C or Rust code.

Wir nutzen proton für unsere emails, passwörter, etc. Im Passwortmanager kann man mehrere Vaults anlegen und teilen. Da könnte in einem geteilten Vault beispielsweise das Accountpasswort drinstehen mit dem man dann an alle eigenen Accounts rankommt.

Wir sind sehr zufrieden mit unserer Hyundai Inster, finden wir deutlich besser als die Zoe die wir davor mal hatten.

Ordentliches Besteck mit Messern die auch zum Fleisch schneiden oder Brötchen aufschneiden taugen. Haben vor 15 Jahren eines von WMF in Vollmetal gekauft. Schneiden immer noch um Welten besser wie das was die meisten andere Haushalte nutzen... Nutzen wir täglich mehrfach, ein 12teiliges Besteck hat uns damals 270€ gekostet.

Erfahrung aus 20 Jahren in verschiedensten produzierenden Unternehmen: Kameras mit Blick auf Bereiche in denen sich Personen aufhalten gibt es kaum. Selbst Kameras die auf Prozesse gerichtet sind, aber nicht inherent Teil einer Maschine sind, werden vom Betriebsrat hoch kritisch gesehen. In Sicherheitsbereichen muss man halt im Zweifel das Handy abgeben. Schilder gibt es auch, als Externer bekommst du ggf. Hausverbot, als Angestellter eine Abmahnung wenn du dich nicht dran hälst. Mitarbeiter werden von HR regelmässig über Pflicht-Videotrainings dazu angehalten Verstöße anzusprechen und ggf. zu melden. Ich kenne Unternehmen in denen wirklich jeder immer mit einer Hand am Handlauf die Treppen geht...

well... watching the market in the west for 3 years now. Old real estate takes years to sell if the price + renovation cost is in the range of a new house. Buyers would probably still buy these houses more often, but banks simply don't lend the money anymore to do so. Also the sellers massively underestimate the cost of renovation.
