leohonexus··on Show HN: I built TikTok but for studying with quizzes from your own notes
Fun fact: The founder of TikTok Alex Zhu worked on an education app but failed so miserably he decided to pivot to musical.ly, which later became TikTok.

Bought both your books, they are awesome :)
leohonexus··on Show HN: Personal Interactive Cantonese Dictionary
I deeply appreciate this - as a native speaker though, some of the translations don't sound as accurate to me. For example, 永遠冇絕對 was translated as "forever is not absolute", but a better translation would be "nothing is absolute", as in 永遠冇(嘢係)絕對.

That doesn't take away from the effort you undertook to curate the slang though, open-sourcing would be awesome as it'd allow PRs.

leohonexus··on Group of 17 London secondary schools join up to go smartphone-free
During my school years, my teacher confiscated a deck of my trading cards and stored them in the classroom drawer.

You could probably see where this goes next - very quickly all my cards were stolen by my classmates, and I could do nothing while I saw my classmates play my own cards, as I had no proof they were mine.

That certainly taught me a lesson or two about human nature, at least at that time...

leohonexus··on Group of 17 London secondary schools join up to go smartphone-free
That an official government document explicitly mentioning that school staff is allowed to search a device without law enforcement (either being present, or authorized by warrant) is problematic in and of itself.
leohonexus··on Group of 17 London secondary schools join up to go smartphone-free
I was curious about the legal grounds that schools have to confiscate student's phones for up to a week, and I found this document from the UK government:

https://assets.publishing.service.gov.uk/media/62d1643e8fa8f...

Some things that concern me:

- Page 19: Staff may examine any data or files on an electronic device they have confiscated as a result of a search, as defined in paragraph 57, if there is good reason to do so.

- Page 20: In determining whether there is a ‘good reason’ to examine the data or files, the member of staff should reasonably suspect that the data or file on the device has been, or could be used, to cause harm, undermine the safe environment of the school and disrupt teaching, or be used to commit an offence.

It also doesn't seem to lay out a limit on the duration for which a device can be confiscated - which makes confiscation for a week look a bit like a grey area to me. Would love to hear from anyone with more experience on this area.

leohonexus··on ROOT: analyzing petabytes of data scientifically
Very cool to see large-scale software projects used for scientific discoveries.

leohonexus··on Rabbit Inc. Faked Their Demo (Again)
Not clearing them from their wrong, but it's worth mentioning that Steve Jobs demo'ed the iPhone while many features were still in development / unstable - he had to follow a "golden path" or else the demo iPhone would likely crash.
leohonexus··on A Mistake in a Tesla and a Panicked Final Call: The Death of Angela Chao
I think it's a case of car manufacturers not optimizing for safety where there's no federal regulations for. There's no incentive for manufacturers to make their cars safer for scenarios not tested by regulation.

I watched a video on car safety about this [1] - initially regulators only tested for head-on collisions, but when they started testing for slightly skewed head collisions (which is also a common crash scenario), all the cars that passed with flying colors previously failed in this new test.

Model X's laminated glass is near impossible to break underwater according to the article.

Instead of a window hammer, in the US you could probably use a handgun to shatter the glass instead.

The Cybertruck though uses "bulletproof glass", so you can't even shoot your way to escape - it'll just make a hole to make the car sink faster.

leohonexus··on Add oil
Another interesting example is "Delay No More", which in Cantonese, sounds very much like a local slang with connotations referring to one's mother.

leohonexus··on Ask HN: I’m an FCC Commissioner proposing regulation of IoT security updates
If a HW company is shutting down due to financial difficulties, the fact they previously paid to get a "license" to make smart devices won't be any incentive for them to continue operating. How does this help the situation other than to further raise the barrier of starting HW companies?
leohonexus··on Brute-forcing a macOS user’s real name from a browser using mDNS
Sounds like that would be a perfect simple application for a go/ link or a Raycast extension, just saying :p
leohonexus··on Ask HN: How do you not take criticism of your work personally?
I would recommend "Focusing in Clinical Practice: The Essence of Change"[1] if you're into reading books. I once took a semester-long course on emotional-based therapy taught by one of its practitioners and it really helped in processing and engaging with my own emotions.

One of the core techniques is to visualize the emotion as another person as you try to talk to it and discover more about what it is you're feeling, eventually coming to a strong connection with the feeling. It's been an epiphany trying to process emotions this way for me.

Hah! I was thinking this: https://xkcd.com/505/
leohonexus··on Ancient Earth Globe
To see life evolve from algae, one would have to live 7.5 million lifespans, assuming one has a lifespan of 100 years. Ancient Egypt is just 50 lifespans away in comparison. That's the most mind-boggling fact I learnt today.
leohonexus··on MSI firmware signing keys leaked
If I recall correctly, at boot time CPUs retrieve the firmware along with a cryptographic signature that verifies the firmware came from the signer. Some boards choose to burn this signature into the hardware using e-fuses. If the signing key is leaked, that means someone can flash custom firmware into the chip and the CPU would be none the wiser, all while operating at Ring 0.

leohonexus··on Convolutional Neural Networks implemented in Minecraft
Probably not possible in this architecture - since probabilities of minecarts are hardcoded, judging from the video that's how they scale random number generation.

I don't live in the EU (nor the Americas for that matter) so I'm speaking from first impressions of browsing the site.
leohonexus··on DNS0: The European public DNS that makes your internet safer
Not affiliated with EU at all. Their branding and wording makes it look like they are until you scroll to the bottom and read the About.

Admittedly I don't live in the EU so to some of you folks the non-affiliation may seem obvious.

leohonexus··on My Plans for 2023
Interesting! Looking forward to reading the upcoming browsers extension / computer hacks book. That being said, there doesn't seem to be a way to follow your progress on the blog?
leohonexus··on PRQL: a simple, powerful, pipelined SQL replacement
SQL query optimisation has been studied since the days IBMers were competing against Quel. If the transpiled SQL has sensible optimisations performance could be equal to or even faster than hand-written SQL. I don't see how this differs from a "language extension" that adds a bit of Pythonic flavour to SQL, which IMO is the right step forward.

I like the webring implementation on your personal site. I wish academic researchers did this, that'll make knowing people in different fields so much easier and fun.

I love Haskell! I once wrote an interpreter for an OOP language with Haskell, and I've loved the elegance ever since.

Hello from Hong Kong, I’m a researcher working on speech to facial mesh models that’s language-agnostic. Currently it’s a comfy Sunday afternoon and I’m at my desk downloading a huge dataset. Feel free to reach out in the comments, I have lots of free time while waiting for it to download. Good day to everyone!

leohonexus··on Computer Saturation and the Productivity Slowdown
What about the adoption of cloud, SaaS, and improvements in information systems in industry (e.g. Flexport for freight)?

The article doesn’t touch on software at all and instead attributes productivity growth purely as a function of Moore’s Law, which seems counterintuitive as both HW improvements and SWE improve the SW running on top.
