Hot take on formulas

Engineering references that specify formulas with variables with specified units, instead of constants with defined units, are a travesty.

I refer to Crane Technical Paper 410 in this instance.

Why would I want

ΔP = 32000 μ L v/d^2 (for laminar flow)

You'd expect this to be a normal formula, which you do your own dimensional analysis, but no. Units are specified. But not even on the same page, no no, on a "nomenclature" page you have to know to look for.

ΔP in Pa

μ in cP

L in m

v in m/s

d in mm

When I could have

ΔP=32 μ L v/D²

and YOU use whatever units you want.

Hell I could even put imperial units in here if I were a masochist. Very upsetting.

Engineering textbooks/technical papers need to find Pure Math Jesus.

Formulas with hidden units? Not even once.

Crane TP 410. How could you?

No End-to-End Encrypted Fediverse?

I really want a Facebook (the old Facebook timeline) replacement, but end-to-end encrypted, and decentralised so there's longevity.

Edit for clarity: I'm looking for a way to share things online, end-to-end encrypted to a wide-audience that knows you but doesn't necessarily know each other.

This is why messaging apps don't fulfil this requirement, and chat rooms (like Matrix) also don't fit.


I love Lemmy, I like the idea of Mastodon (twitter-like sites just aren't my thing. ActivityPub rocks. However, none of them are encrypted.

PixelFed is neato, but I don't plan sharing my personal photos with the whole of the internet, which seems to be the only choice with ActivityPub.

Signal and other encrypted messaging apps are great, but are for direct messaging. Where are the encrypted social media apps?

Matrix is cool and all, but it's aimed at groups. Like discord / MS teams replacement.

Someone told me about Futo Circles, which seems to tick all the boxes and built on top of Matrix, but it's currently abandoned.

Are there any other alternatives? My wallet is open, I would very much like to use such an app. I am no programmer, so sadly cannot take on the mantle of continuing the Futo Circles project.

Ideas for Signal Android Automatic Cloud Backups?

I'm aware of how to set up chat backups on Android, but this only makes local backups that you have to manually upload or copy.

I'm trying to find a solution where I can set and forget backups to the cloud.

My requirements are:

  1. It doesn't require me exposing the rest of my file system/cloud storage to a third party app without scoping (filesync works, but doesn't meet this criteria).
  2. It can upload directly to a cloud service

So far, no dice :/

Is there some workaround?

P.S. my potential solution is move Signal to my Shelter Work profile, where I do have filesync installed, but then I won't have contacts access, which is a slight pain (and because I don't want to create contacts in my work profile).

I dislike charity.

Most recent example: I was asked to participate/lead our team's Movember campaign at my company.

How I politely declined: oh sorry, I'm a bit too busy with my personal life and work projects this year.

My unpopular opinion I couldn't say: it doesn't align with my values.

Movember raises money and promotes awareness of Men's health. Nothing wrong with the organisation themselves, but frankly I think the paltry couple of thousand of dollars our (pretty large) company manages to raise each year is a waste of time.

If we taxed corporations a fraction of a percent more on corporate profits we would bring is orders of magnitude more money than individuals asking others, out of the kindness of the hearts, for money.

Health research shouldn't have to beg for money, the government should just fund it with tax dollars. Taxes that you don't get to choose to pay. Other than by voting.

I hate fun runs, and do subtly judge those who participate in them, especially because (I think) they skew towards wealthier people, and it's their way of making themselves feel good for raising money for cancer or whatever, and then turn around and vote for tax cuts, and use accountants to make their tax liability as low as possible - something poorer people can't afford.

I used to give money to charity when I was younger. But I honestly think it's silly now, and it ought not have to exist.

(Mods, this is politics adjacent, but I feel is general enough to be compliant, since I'd say most people view charity organisations mostly favourably)

Literally Nineteen Eighty-Four

cross-posted from: https://lemmy.world/post/21049862

The only numbers I will ever spell are one and zero, and only when using them as a pronoun, or for emphasis, respectively.

Is there ever a reason to not to use symbols when dealing with numbers? Why would "fourteen whatevers" ever be preferable to "14 whatevers". It's just so much easier to read numbers as symbols, not spelled out.

(Caveat, not including multipliers, like "273 billion").

Google Allows Creditors to Brick Your Phone

I installed NetGuard about a month ago and blocked all internet to apps, unless they're on a whitelist. No notifications from this particular system app (that can't be disabled) until recently when it started making internet connection requests to google servers. Does anyone know when this became a thing?

Edit 2: I bought my Pixel 6 phone outright, directly from Google's Australian store. I have no creditors.

Were the courts not enough control for creditors? Since when are they allowed to lock you out of your purchased property without a court order?

I don't even live in the US, so what the actual fuck?

Edit 1: You can check it's installed (stock Pixel 6 android 14) Settings > Apps > All Apps > three dot menu, Show system > search "DeviceLockController".

I highly recommend getting NetGuard, you can enable pro features via their website if you have the APK for as low as 0.10€, but donate more, because it's amazing. You can also purchase via Google Play store.
