aduitsison A Faster Alternative to Jq

...and because it's going to burn a million times the energy of what jq would require.

aduitsison Thoughts on slowing the fuck down

And maybe it's dangerous for one to think they're doing engineering when in reality they're doing craft work.

aduitsison Monosketch

+++ Monodraw is awesome!

aduitsison Just the Browser

For Firefox, I think that disabling the telemetry and the studies is not going to help Mozilla improve the browser.

aduitsison Don't Download Apps

IIUC, contactless payment via apple pay does have a secondary card number of sorts that's linked to your original card.

I once accidentally paid for AppleCare with apple pay (a mistake), so when at some point I switched phones I had to get new secondary card numbers tied to my physical cards. The old secondaries went away when I wiped my old phone, so AppleCare was no longer able to draw the monthly payment. The number in the invoice was likewise not the original physical card number, but some other number.

Whether the secondary numbers are easier or impossible to track is certainly a question, but I believe there's always a number.

aduitsison Cool-retro-term: terminal emulator which mimics look and feel of CRTs

Yes, correct! If you check out https://ghostty.org/docs/config/reference, the iPreviousCursor is available, so it can be used against the iCurrentCursor to produce a fading effect. But I think the entire previous framebuffer isn't there (yet).

aduitsison Cool-retro-term: terminal emulator which mimics look and feel of CRTs

It can only apply shader(s) to the current frame I think. To produce the crt ghosting you'd probably need access to the previous frame (not an expert).

aduitsison Ask HN: How does my school block DoH?

(You need to setup your DNS to respond in a certain way for a canary domain)

aduitsison Moving objects precisely with sound

One step closer to the sonic screwdriver from Doctor Who.

aduitsison Rete algorithm

Hey! I was using CLIPS in my network management PhD work, but life happened and I was absorbed by my profession. Maybe one day I'll dig up the half finished material and continue, who knows.

CLIPS is one of those definitely underrated gems, many many thanks for what you are doing!

aduitsison Ancient City Found in the Amazon

Why is this downvoted? It's 100% relevant.

David Grann is a well known New Yorker contributor and, before the book, has also written an article named "Lost City of Z": https://www.newyorker.com/magazine/2005/09/19/the-lost-city-...

aduitsison Apple unveils M3, M3 Pro, and M3 Max

Mac Mini with the M2 Pro can drive 3 monitors, Macbook Pro with the M2 Pro only 2.

aduitsison We are beginning to roll out new voice and image capabilities in ChatGPT

Fortunately it's not like StackOverflow has been used as training data for LLMs, right?

aduitsison Why Perl?

If you feel more comfortable with Python for the task at hand, why not use it?

That's good and it's actually the Perl way, Perl was always about helping getting stuff done.

aduitsison Why Perl?

Programming language police, pull over.

aduitsison LHC experiments see first evidence of a rare Higgs boson decay

Our future technological improvement hinges on basic research. We can certainly iterate and improve technology, but the amount of improvement is always bound to hit a physical limit sooner or later. Doing basic research will actually move the physical limit.

aduitsison Google Pixel Fold

For some of us that are not in the US, this product doesn't even exist. 2023 and still somehow the Pixel doesn't sell in several countries in the EU.

aduitsison Ancient Greek terms worth reviving

Totally, it's actually harder for Greeks that already speak modern Greek to pronounce Ancient Greek using Erasmian pronounciation :).

aduitsison The tug-of-war over server-side WebAssembly

Deep respect to the CloudABI folks, a project which inspired the WASI ideas:

> CloudABI is no longer being maintained. It was an awesome experiment, but it never got enough traction to be sustainable. If you like the idea behind CloudABI, please consider looking into the WebAssembly System Interface (WASI). WASI's design has been inspired by CloudABI.

edit: https://github.com/bytecodealliance/wasmtime/blob/main/docs/... is a good reference and also mentions the Capsicum framework (https://www.cl.cam.ac.uk/research/security/capsicum/). Which is present in FreeBSD for several versions btw.

aduitsison The Shit Show

At this point the signal to noise ratio on Mastodon is amazingly good. Who would have thought that just displaying the timeline would be so refreshing.

Please read the article, it says the opposite of what you think it says.

aduitsison Meli – email client in the terminal, in the spirit of mutt

Elinks for rendering html mail and antiword for rendering word documents inside the mutt message view.

aduitsison Meli – email client in the terminal, in the spirit of mutt

Not exactly the same, but in mutt, there is a simple language which you can use to refer to a subset of the messages in your view. E.g. "~U" will match you unread messages, etc.

You can group tag messages on mutt with any pattern you'd like and then move them. Or, you can limit your view to what you want to move, select some and then move them.

aduitsison Competitive Programming with AlphaCode

Otherwise the AI will just over-fit the unit test case subset.

aduitsison A UX designer walks into a Tesla Bar

I understand, the car my not have a (2)DIN slot. That's a definite regression. And very costly if your car stereo dies out of warranty I might add.

aduitsison A UX designer walks into a Tesla Bar

Hello, honest question, can't you install an aftermarket car stereo that has CarPlay from any reputable manufacturer?

aduitsison Consider SQLite

Would Redis be a valid solution for your case?

aduitsison The Big DevOps Misunderstanding

Thank you for the post! At some point years ago I started realising that most problems in SNMP are stemming from badly implemented SNMP agents. Those problems can be:

1. Returning values different than what the MIB says.

2. Missing values that are not optional in the MIB.

3. Broken getnext code that returns an incorrect oid, which could even lead to loops. Net-snmp will detect it, but proper snmpwalk gets broken.

4. Broken getbulk repeater code that can cause crashes if the repeater is too large.

5. OIDs that will crash/stall/slow the agent.

6. Implementations that cannot handle simultaneous requests. Admittedly this is notoriously difficult to achieve: most MIB implementation code is not reentrant for various reasons.

7. SNMP SET is very difficult to implement, cannot be meaningfully used for almost anything beyond extremely simple stuff.

8. UDP encapsulation can cause MTU/fragmentation issues that are a nightmare to debug. Net-snmp actually implemented transports such as TCP and it was very nice, but it never caught on in general.

Bonus, there is also the not related to implementation problem of:

9. The query semantics of SNMP are non-existent, and the indirection in the SMI is cumbersome, which means that as a client/manager you'll have to do all sorts of data wrangling to find what you need.

aduitsison Underrated Reasons to Be Thankful

That today, thousands of years later, we have managed to retain what those people said or wrote is also a very good reason to be thankful.

aduitsison Alan Kay at UCLA (2016) [video]

Slightly off-topic, but besides all the important contributions of Alan Kay, there is also his famous quote:

> Point of view is worth 80 IQ points

The wisdom of it is that it suggests a profound change in the point of view of what intelligence is. Although I suspect this must have been researched well before the quote, it summarizes so beautifully the fact that intelligence isn't just some single-dimensional hard coded genetic trait, but something transferable and even contagious through language. Love that quote.
