galacticdessert··on The Golden Age of British Ice Cream
Just for my understanding, what is the issue with xanthan gum and locust bean gum? You need thickeners, stabilizers, and emulsifiers if you want high quality ice cream and that applies to both industrial as well as artisanal.

Xanthan or Agar Agar are commonly used even in household gelato (think a 1kg ice cream machine or something like a Ninja Creami - which is one of my own ever favorite and most recommended appliances) to reduce the formation of ice crystals. Locust Bean Gum and Guar Gum or is a thickener and can greatly improve the creaminess of the final product.

Historically people used a lot of egg yolks as emulsifiers in ice creams, but there are reasons to limit them or directly not have them in your gelato. Think even just fat content, or allergies, or personal preference. For that you will need some sort of natural gum and as far as I know there are no known health hazards associated with them (unless you consume crazy amount like 10-20g/day, which means you have to eat it from the jar with a spoon... I would not recommend)

galacticdessert··on Germany Forces Lexus to Remotely Kill Car Heating in Dead of Winter
The tone in the article is so off. We are clearly headed for a climate disaster, being whiners about having to manually de ice your windshield is so very childish.

I understand there is a broader topic of regulators impacting what can and can’t be done but isn’t that just having a government?

galacticdessert··on Why some friendships end after kids come into the picture
Yeah you are being a dick. Hope you will also have a little one one day and maybe then you will realise how absurd you having to correct their kids sounds like ;)

So did McKinsey ;)
galacticdessert··on Buy well, buy once
Small and efficient ICE engines are as proved a technology as it gets. If you end up buying a V6 engine now it is not because of how good or reliable the engine is, it is either nostalgia or status symbol. So, please don’t and be more mindful of your emissions.

Oh I soooo miss Fotolog, was a great concept
galacticdessert··on A Fast Excel Formula Parser and Evaluator
As I consultant that works extensively in Excel, I understand your point. The lack of decent syntax highlighting, auto-indentation or “IDE mode” instead of the formula bar can be painful. Especially when working with models developed by others.

On the other hand, you can see it as a feature. It forces you to keep your formulas short, break them down in helper columns and overall make your logic cleaner. If you are writing a 4 line long formula, you are doing something wrong. Sytax highlighting would still surely help, but it is not a replacement for clean modelling.

Trilium Notes might be what you are looking for. Very very pleasant

galacticdessert··on Thunderbird 91.0
I really like Thunderbird and I use it as my primary personal email client. Just, where can I pay to speed up the development of this feature?

https://bugzilla.mozilla.org/show_bug.cgi?id=213945

I find a proper 3 pane view to be essential in 2021

There is an extension for it -> https://addons.thunderbird.net/en-US/thunderbird/addon/gmail...

Not super great visually, but works ok

galacticdessert··on Launch HN: Heimdal (YC S21) – Carbon neutral cement
Cheap green electricity at less than 50 $/MWh should not be a problem, most PPAs are already getting signed at costs substantially lower than that.
galacticdessert··on Launch HN: Heimdal (YC S21) – Carbon neutral cement
Absorbing large amounts of CO2 happens every second since 2-3 centuries at this point, and is the main driver of ocean acidification and subsequent coral bleaching, loss of wildlife, etc. If the mentioned process could "recycle" the CO2 needed for lime production, then it could be a big win for a very hard to decarbonize sector.

What is still to be checked is how more expensive this lime will be, and how it will stack up compared with traditional limestone+carbon tax

galacticdessert··on 12 requests per second: A realistic look at Python web frameworks
I feel like when you need to create value and make a product, better to do it in a language you know. Product value is not directly proportional to product performance or raw HTTP request serving time.

I for instance know a bit of F#/C# and Java, but would probably pick Python to make a new product just to remove that mental barrier of not having my lack of language knowledge in the way of things

galacticdessert··on An SQL Solution for Jupyter
Would not the latter be the task of a language library? i.e. Pandas with read_sql()?
galacticdessert··on An SQL Solution for Jupyter
Agree this would be awesome. I reckon you could obtain something similar with pandas with pd.read_sql("<query>"), but a dedicated SQL cell akin to markdown cells would make it much more pleasant
galacticdessert··on LibreOffice 7.1 Community Edition
Don't know about the comment author, but in consulting huge excels are quite the normal. Especially when dealing with data driven domains such as energy
galacticdessert··on Rule Engines and Knowledge-Intensive Processing with Answer Set Programming
The article feels somewhat half finished: it introduces the topic, an implementation, and walks the reader some examples. It lacks the so-what, why and what ASP can do for me concretely, and where I can find more.

Still, though, I am fascinated by the subject. These days I am toying with an idea that revolves around optimal scheduling ofenergy consuming asset based on energy prices, external market inputs and business rules (such as this asset must be on for at least 10 hours per day, or temperature control, etc.). Would ASP help here in working towards an optimal solution in almost real time?

So you don't make bad performance choices in C?
galacticdessert··on PyInstrument – A statistical Python profile that focuses on the slow parts
py-spy seems also very interesting, thanks for linking it. I always found cPython to be quite difficult to work with, and usually reverted to line_profiler or some sort of UI for cprof files. The main added benefits of pyInstrument to me is the high signal vs noise ratio, as it is evidently clear what is taking the most time while retaining the option to dive deeper.

I am also curious to try out the on-demand profiling integration with Flask, seems like a cool thing to have running in the background for my side projects

galacticdessert··on Openproject: Open-source project management software
Could you elaborate on it? It sounds a lot like the MS Project/Omniplan way. Do you/How do you integrate with the code development workflow and version control?
galacticdessert··on Espruino: JavaScript for Microcontrollers
Any thoughts on the development experience of this versus the Elixir based Nerves project, putting aside obvious platform differences (i.e. the BEAM being concurrent and resilient by design vs JS having a ton of libraries, etc.)?
galacticdessert··on OptaPlanner – constraint solver for optimizing planning and scheduling problems
Yep
galacticdessert··on You're Allowed to Write Slow Rust Code
True, but I expect that only ~2% of programs to ever run into this problem
galacticdessert··on Costs of running a Python webapp for 55k monthly users
And most of the time isn't, right? I have seen project managers keeping a whole development team of 10+ developers busy for entire sprints to "cut down the infra costs", without realizing that the dev team costs 500+ kEUR/quarter, while the hosting costs were something like 7/8 kEUR/month.

Also, related aritcle -> https://m.signalvnoise.com/only-15-of-the-basecamp-operation...

galacticdessert··on Costs of running a Python webapp for 55k monthly users
Hey, good job on your project!

The only thing I wanted to say is that the time spent learning a bit of SQL pays off massively. Perhaps something for your todo list :)

galacticdessert··on Introduction to Ada
Totally unfamiliar with Ada, but reading below it seems that type safety and concurrency are big selling points of it. In which way would this better than a modern functional language, say F#?

galacticdessert··on Mozilla lays off 250 employees while it refocuses on commercial products
People have incentives. Google employees likely are there to have the experience on their resume and monetize later. Mozilla people work for a non profit, hence they are probably motivated by social activism rather than money or fame.
