You’ll encounter math eventually. It could be as simple as implementing linear interpolation for a custom type, or understanding why a type is not suited for a particular application (e.g. never use floating points to represent money). If you delve into low-level networking, you’ll need a good understanding of binary/decimal/hexadecimal conversions and operations. If you go into game development or graphics, you won’t survive without a deep understanding of vectors, matrices, and quaternions. Any kind of data science is just math translated to a machine-readable language.

In my opinion, knowledge of the basic concepts is more important than being good at actually performing mathematics with pen and paper. For example, if you need to apply a transformation to a vector, nobody expects you to whip up a program that does the thing. Instead, you should immediately know:

• what a transformation is (translation, rotation, scaling, projection, etc),
• that each transformation has a corresponding transformation matrix,
• that you’ll have to deal with inhomogeneous and homogeneous coordinates, and
• that you’ll have to combine the transformation matrices and the original vector.

That abstract knowledge will give you a starting point. Then you can look up the particulars – the corresponding transformation matrices, the method to convert between inhomogeneous and homogeneous coordinates, and the process of matrix multiplication. I know because I failed calculus.

Do people actually believe Apple’s hogwash about privacy?

VS’s built-in .NET debugger is top tier, though. Especially the ability to edit code while it is running.

FLACs, Tidal’s downloads and cache, photos from work that I can use as evidence, and a fuckton of memes. My previous phone had 64GB internal and I just about filled it before it died.

Time-based one-time passwords. It’s been used for years for multi-factor authentication.

This. I’ve had issues at work while imaging classroom computers where some would finish in ~30 minutes and a few would need hours. All of the computers used Cat6 cables. This being a classroom, and students being absolute wankbags, they kept yanking the computers and kicking the cables, so the wires came loose from the plugs. I later used ethtool to debug the slow computers – the switch would only allow 10baseT link modes.

I just simply set up a script to export my Trilium notes

edit the notes with an external editor, and then you can just re-import the note

Those two lines right there.

I value interoperability between software. Using a container format to store plaintext files and metadata introduces an XKCD 927 situation where it’s just another reinvention of the wheel that requires additional software support or a whole other workflow for no real benefit. Why is it necessary, for example, to store plaintext data and the related hierarchical structure in a container format when the same feature is already present in the filesystem with files and directories? It adds unnecessary complexity, roadblocks, and points of failure.

I’m using QOwnNotes at the moment. If I want to edit a note, for example, using neovim through SSH, all I need to do is navigate to the markdown file and open it. No scripts, no export/import. Only text files, and that is all it ever needs to be.

They all offer more or less the same network services with different UIs.

OpenWRT is specifically designed to work as a lightweight system running on consumer-grade routers. If you want this, you’ll have to check the website’s Table Of Hardware to determine if your hardware is compatible.

OPNsense and pfSense are general-purpose FreeBSD-based operating systems that you can run on discrete computers or in VMs that act as network gateways. All three are free/gratis, but you have to make an account and go through the store page to download pfSense.

I personally use OPNsense in a VM.

Surely you can. Modern electric stovetops use infrared radiation from a wire coil to heat cookware. The stovetop is covered with a ceramic that allows infrared radiation to pass through, and if you put something on it, it’ll absorb the radiation as heat. The technology is also scalable to industrial applications.

I’ll let Brown Jacket Man explain the principle. https://www.youtube.com/watch?v=ff04ecF9Dfw

(edit) My house has an electric water heater that was built in the Soviet Union. It uses a ~200-litre tank with a large heating element inside.

1. Better insulation.
2. Heat pumps.
3. By the time gas heating is eliminated, climate change will have solved that problem.

Evil is evil, Stregobor. Mozilla is still a company that does company things. The current CEO has worked for AirBNB, Ebay, and Paypal, so not an inspiring history there either.

If you really, really, really don’t want to buy a keyboard and monitor, you can buy a USB KVM console, but it’ll likely cost more. Something like this: https://www.startech.com/en-us/server-management/notecons01

Oracle was one of the first companies on my personal shit-list. I feel validated.

Thinking about it, being circumcised probably reduces sensitivity a lot more than cranking the hog on the regular.

I’m in the same position, and it feels so damn powerful. I’ve convinced an entire university to ditch Ubuntu in favor of Linux Mint, and I’m also advocating for replacing our aging VMWare servers (with a soon-to-expire license) with Proxmox.

Damn, I had no idea netcat had a hardware implementation

For many years now, Apple has been sustaining its quasi-monopoly in the smartphone ecosystem by drip-feeding features that have been part of the baseline for other brands, and having the most hard-core blinkered Apple cultists proselytize about what innovations they (supposedly) represent. This advantage doesn’t exist in the silicon or VR markets. They’ve managed to keep their CPU successful because it’s built on existing technology and because of vendor lock-in, but the Vision Pro didn’t have the same training wheels and ate shit right at launch.

In case it isn’t obvious, I don’t have many positive feelings towards Apple.

Not exactly. When you select a text and copy it, the two selections will end up containing the same text, but you can write to either selection without affecing the other by using an API, e.g. a website’s “copy to clipboard” button, or xclip/wl-copy.

Clipboard managers with a history feature are an altogether different layer on top of the standard selections. Plasma’s clipboard manager only cares about the clipboard selection, and even then, there are exceptions (e.g. copying a password for KeepassXC doesn’t save it in the history).

Yes. X11 replaced X10’s obsolete cut buffers (which can be modified by any process) with state-of-the-art selections. There are three selections in X11: a primary, a secondary, and a clipboard.

In modern desktops, the primary selection is overwritten every time you select some text (including in the terminal), which makes its content very ephemeral. You can paste it with the middle mouse button.

The secondary selection is generally not used, but it’s present in the specification, and you can use xclip -selection secondary to access it. Wayland doesn’t seem to have a secondary selection.

The clipboard selection is what most people understand to be THE clipboard. You have to write to it explicitly (through a keyboard shortcut, API, or CLI tool), and its content persists until it is overwritten, explicitly cleared, or the X server is killed. While the primary and secondary can only contain text, the clipboard can contain many kinds of data.

Gee, X11! How come your mom lets you have THREE clipboards?
