avian··on YouTube addresses lower view counts which seem to be caused by ad blockers
I don't think YouTube needed to do anything. The change influenced creators' bottom line so they are motivated on their own to mobilize their viewers against this change.

The vape comes with a miniature laser-engraved WEEE crossed-out trash can symbol so everything is fine.

avian··on Tarsnap is cozy
Storage Box with Borg backup can be setup to work almost identically to tarsnap.

The only real security feature missing is write-only access to the repository (Borg backup in theory supports it, but in practice it's impossible to use it in a way that prevents a compromised host from deleting it's backups - like tarsnap does).

In theory it is less reliable than tarsnap (AWS S3 compared to a single copy on a Hetzner's drive).

Storage Box is significantly cheaper for any kind of real-life backup sizes in my experience.

Borg requires more work to setup and configure compared to tarsnap. There's typically some scripting involved that's unique to your setup and I found that I had more documentation to study before I understood how to use Borg correctly.

A know a few people that have very low opinion of Borg's code quality and stay away from it because of it (I haven't studied it first hand)

avian··on Tarsnap is cozy
I've been using tarsnap for years and am in the process of migrating away from it.

Things that are not cozy:

1) There's no way to monitor your monthly spend per host/credit left on the account/etc. apart of logging into your account in a browser and manually keeping a spreadsheet. There's no web API to do it. You get an email warning when you have about 7 days of credit left. That's it.

2) Nothing is "a precious few megabytes" anymore. What seems like a negligible monthly spend at first can quickly grow up on you and soon you're spending highly non-trivial amounts. Which you might not notice due to 1) unless you are diligent in your accounting.

3) tarsnap restores are slow. Really really slow. A full restore can take days if you have non-trivial amounts of data (and make sure you have enough credit in your account to pay for that server-to-client bandwidth!) My understanding is that throughput is directly related to your latency to the AWS datacenter where tarsnap is hosted. Outside of north America you can be looking at nearly dial-up speeds even on a gigabit link.

Again, a problem that can surprise you at the most inconvenient time. Incremental backups in a daily cronjob tend to transfer very small amounts of data, so you won't notice the slowness until you try to do a full restore. And you generally don't test that very often because you pay for server-to-client transfers.

There are some workarounds for 3) and there's a FAQ about it, but look at the mailing list and you'll see that it's something that surprises people again and again.

avian··on Melvyn Bragg steps down from presenting In Our Time
In Our Time has been my favorite podcast to listen. It made me appreciate how well moderated a discussion among experts can be and how poorly most moderators on other radio programs or conference panels do their jobs.

My complaint with In Our Time is that BBC started inserting the "this program is supported by ads outside of the U.K." ads in the middle of the discussions. The ads start and end with an extremely annoying loud chime that just blows out the speakers if I have the volume turned up to understand a guest that's speaking in a more soft voice.

avian··on OpenAI's ChatGPT Agent casually clicks through "I am not a robot" verification
I have the same experience. My assumption is that if the website serves me the "click all the traffic lights" thing it's already determined that I'm a bot and no amount of clicking the traffic lights will convince it otherwise. So I just close the window and go someplace else.
avian··on Rotring 600 Ballpoint Pen
I looked up some pictures of this lefty-handed curl and I suddenly feel immense gratitude towards the people from my childhood that taught me how to use my left hand to write in a practical and comfortable manner.
avian··on Rotring 600 Ballpoint Pen
As a counter example, I'm left handed and write hundreds of pages per year in a left-to-right language and don't have issues with smudging lines with my palm.

Maybe the inks I use dry fast enough (Parker Quink or Pelikan 4001) or it's the way I learned to write back in school.

avian··on Rotring 600 Ballpoint Pen
> One lasts generations

Multiple Parker Vectors I had typically lasted a few years of use each before the plastic windings between the pen head and the holder wore out or broke.

My Pilot Metropolitan did the same just a few months back.

I still have the high-end pens my grandfather used that, while mechanically still sound, I am unable to get the ink flowing through them.

I love writing with fountain pens, but long lasting they are not in my experience.

avian··on Why do electrons not fall into the nucleus?
> If I take a small piece of matter and shake it for a long time, then don't all its electrons and protons emit electromagnetic radiation and lose energy?

Yes, they do. But it's only a very very tiny amount.

You're shaking both the positive (nucleus) and negative (electrons) parts of the atoms. The electromagnetic fields outside of the atom almost perfectly cancel out. This means that the acceleration only affects the very small residual field and there is very little radiation at far distances, unless you shake it really really fast.

Another way to look at it is that atoms are in fact already constantly shaking by themselves because of thermal movement. And this does in fact result in them emitting radiation: objects at room temperature will radiate in the infrared spectrum because of this.

The trick is that thermal movements of atoms are very fast compared to moving something by hand. Room temperature infrared radiation frequencies are on the order of tens of terahertz. Compare this to manually shaking an object at (say) 10 times a second. With some hand waving math this is like giving it an equivalent temperature of around 10^-10 kelvin. It will radiate extremely long wave radio waves, but such a tiny amount that it will be completely unmeasurable.

avian··on Cholesterol-elevating substances found in coffee from machines at work
From the paper linked in the post:

> [...] boiled coffee was poured through a two-layer polyester/acrylic sock (an occasional household recommendation as potential substitution for a paper filter)

No kidding. I thought the sock was just a cute icon they used for the graphical abstract.

avian··on Debugging Hetzner: Uncovering failures with powerstat, sensors, and dmidecode
As an electronics engineer I have no idea what the author is talking about here and was about to post the same question.
avian··on The 88x31 GIF Collection
I was wondering where the odd 88x31 size came from. According to this [1] it's basically because at one point GeoCities used a GIF of this size and then everyone copied it.

avian··on Playful Drawings That Charles Darwin's Children Left on His Manuscripts
All I get is "Error 405 [country] users must use proxy."

I wonder what that's about. GDPR?

avian··on Cracking a 512-bit DKIM key for less than $8 in the cloud
As a small mail server admin I see this less about security of messages originating from me and more about the possibility of spammers sending DKIM-authenticated mail as coming from me (and resulting in shadow bans at gmail, etc. which is a huge pain to deal with)
avian··on Open source maintainers are drowning in junk bug reports written by AI
LLMs/generative AI is a significant change to what we had to deal before. Both in terms of volume and accessibility to the common fuckwit (to borrow the term from another thread) and in terms of moderator time per interaction (because its now significantly harder to recognize this sort of content).
avian··on It sure looks like OpenAI trained Sora on game content – that could be a problem
> Generative AI can be used for copyright infringement - just like any creator technology could be.

And yet, all generative AI services are pretty confident that copyright infringement is not something you should worry about when using their outputs.

For a example, this FAQ from Cursor:

> Who owns the code generated in Cursor?

> You! Regardless of whether you use the free, pro or business version of Cursor, all generated code is yours and free to be used however you like, including commercially.

Note how it's specifically not saying "it's up to you to determine if the code infringes on any of the million codebases we trained our models on".

The difference with video and Sora is that it does this with properties of entities that actually have some considerable legal departments behind them.

avian··on OpenAI o1 system card
The section on regurgitation is three whole statements and basically boils down to "the model refuses when asked to regurgitate training data".

This doesn't inspire confidence that the model isn't spitting out literal copies of the text in its training set while claiming it is of its own making.

avian··on Raspberry Pi Pico 2 W on sale now at $7
Any recent news on the GPIO issue on RP2350? Will they ship updated silicon at some point?

https://hackaday.com/2024/09/04/the-worsening-raspberry-pi-r...

So far it seems the message from Raspberry Pi is "we documented the bug, so the issue is closed":

avian··on Two rare Covid vaccine side-effects detected in global study of 99M
I guess this is the study?

https://www.sciencedirect.com/science/article/abs/pii/S02644...

As far as I understand, they used the 42 day window to associate the side-effect with the vaccine.

Have there been any longer term studies, beyond 3 months after vaccination?

avian··on HP raising Instant Ink subscription pricing significantly
Yes. It works fine in Linux. Don't get one if you are printing infrequently. You will just have dried up/clogged heads all the time.
avian··on Discord monetization: microtransaction stores and paid 'exclusive memes'
You're getting downvoted, but I think low text density contributes to the low quality of conversation. I've commonly witnessed conversations that were going around in circles, with people just tuning in and re-asking questions that were already asked and answered in the same conversation two or three page scrolls up.

If it's not on the bottom screenful of text in a channel it might as well not exist on Discord. Which is funny, because one thing that people really like to bring up when comparing IRC to Discord is its lack of persistent history. It turns it doesn't make much practical difference.

avian··on I have received a $100k sponsorship for Ladybird browser
> it encourages more conversation that are visible to more people since everything people say is not going to be trivially searchable for all time by anyone.

It also encourages more people to be assholes in my experience. I'm sure there are well moderated chats out there associated with open source projects, but I had several such abysmal experiences with Discord in the past that I'm completely done with it.

avian··on Social media for AI bots: “No humans allowed”
Most other languages (at least the ones I know) are already hugely polluted by useless content that was (badly) machine translated from English. Such spam sites are now a majority of search results for me when I use Duckduckgo or Google.
avian··on At last, the Raspberry Pi shortage is finally coming to an end
You are both right.

Supply was allocated to businesses, but there was not enough for every business, so quite many of them could not buy Raspberry Pis for their products.

Then again, everyone was having major supply issues. Yes, you could pivot from the "hobby" R. Pi to a "serious" industrial brand that had sales people talk big words about how they don't have these "beginner player" issues - right up to when it was time to deliver and suddenly they start talking about 100+ week lead times and 2025 delivery dates...

avian··on Decoding small QR codes by hand (2012)
These are cool and definitely a much more interesting hack than just sticking a company logo in the middle of the code in Photoshop. But I've never seen one of these in the wild.
avian··on Decoding small QR codes by hand (2012)
> 99% of the QR codes you encounter don't have any missing bits

I see a lot of cutesy QR codes out there that include a logo in the center.

These are basically intentionally damaged and depend on error correction to recover the missing bits that are covered by the logo.

avian··on Having a 20GB file that lets you ask an offline computer any question is amazing
Correct. Parent commenter seems to be asking questions they already know the answer to.

Those are the wrong kind of questions.

They should only ask the questions about things they don't know anything about.

ChatGPT gets those right every time.
