I still don't understand the title, no matter how hard I try. Is there a word missing? A misspelling?

New comment by jdubb in "Raspberry Pi update removes the default user"

Just yesterday I've been flashing Raspberry OS to a micro SD card. Not succeeding with Balena Etcher, I opted to use the RPi imager tool, which did work (which might be an issue not in any way related). After that I added the `ssh` file to the boot partition and tried connecting to it via SSH. Providing username pi and password raspberry, connecting fails with invalid password, no matter how many times I tried. Searching all over the internet for whether the password was different nowadays, but coming up with zip, frustrated, I went to bed.

Reading this today it hits me that this change might just be the cause.

If that turns out to be the case, there should really be some indication in the RPi imager tool.

Very recognizable. I've used Hugo for exactly one website, as a first introduction to static site generators. The site still runs, and if I need to change something running the `hugo` CLI still works. But it wasn't easy to get started, with all these new concepts, and this site explains clearly the trouble I had.

Perhaps it's expected that when you use Hugo, you already recognize most concepts from other static site generators?

Since a few months, firefox by default doesn't switch from incognito back to normal mode when I close the only remaining incognito tab. Can probably be attributed to increased privacy, I suppose, encouraging the use of incognito mode. But there's no setting to change that back. Over time, more of these minor annoyances appear which I'd need to dig in my memory for. Luckily, it's a relatively small price to pay, overall I'm just happy to have adblocking in the browser.

Using YouTube only via Firefox with the uBlock Origin plugin works pretty well too. The simple solution without requiring any additional apps. Firefox has its own quirks which are discussed on Hacker News at length, but it's good enough.

Actually, I've considered installing an older version of Firefox and disabling updates. But I feel that might pose security risks, and if at some point there's a novel virus requiring updating, I'm afraid the shock might be too big, as compared to a little shock every few months. Still considering what's wise here...

There's https://en.wikipedia.org/wiki/Deep_Zoom for example.

> A DZI has two parts: a DZI file (with either a .dzi or .xml extension) and a subdirectory of image folders. Each folder in the image subdirectory is labeled with its level of resolution. Higher numbers correspond to a higher resolution level;[6] inside each folder are the image tiles corresponding to that level of resolution, numbered consecutively in columns from top left to bottom right.

New comment by jdubb in "uBlock Origin works best on Firefox"

jdubb — Fri, 09 Apr 2021 21:58:31 +0000

I agree, ublock origin was my single most important reason to finally switch from chrome mobile to firefox mobile.

There are some quirks though, minor annoyances that every so often get introduced in updates. For example, when closing the last private browsing tab it doesn't automatically show the regular tabs any more, but instead requires three more taps. But I'm happy to ignore those for the sole reason of having fully functional ad-blocking.

Another option you have is to put the firefox search widget above you google search widget in your home screen. It's a bit ridiculous that the Google search bar can't be removed, but this is second best.

Pinch to zoom doesn't work, and I can't find another option to increase the font size. This is on mobile. Are you by chance on pc?

For those like me who still couldn't find it: there's a small menu button on the top left.

Maybe it's because I'm on mobile, but it's a bit hard to see.

jdubb — Mon, 30 Nov 2020 16:38:54 +0000

For those wondering, like me, what SymPy is, the top of https://docs.sympy.org/latest/index.html explains it:

> SymPy is a Python library for symbolic mathematics.

Both the release notes as well as the readme of the github repository don't explain it (or at least I couldn't find it).

As I mentioned elsewhere, this is because the original title was something like "Kali Linux switches from bash to zsh".

I believe that this is caused by the title originally being (something along the line of) "Kali Linux switches from bash to zsh".

Exactly this. It uses all the dark patterns similar to sites like techcrunch. Is the incentive so big to have these trackers enabled?

New comment by jdubb in "Ask HN: Should Techcrunch be banned on HN?"

jdubb — Tue, 10 Mar 2020 22:28:28 +0000

Evert time I see a techcrunch link on HN I automatically skip it. The site's cookie pop-up has all the dark patterns.

If I go to techcrunch.com, the cookie pop-up has a long piece of text, containing a few inline links tot e.g. a "Privacy center", and the two buttons, "Accept" and "More information". Clicking "more information" shows a button "Manage partners " and "Accept". Clicking "Manage partners" shows a blob of text and links to all the partner websites. Clicking "back" and then the aformentioned "Privacy center" leads to a different website all together. I still haven't been able to find the cookie settings, if they're available at all! And all the while, clicking "Accept" is only a single button away.
