idatum··on AM radio law opposed by tech and auto industries is close to passing
I believe this is why aircraft use AM?
idatum··on Show HN: Dillo 3.1.0 released after 9 years
Yes, same -- for me a '98 Toshiba laptop running NetBSD. Nicer to use compared to lynx but not bloatware.
idatum··on FCC fines largest wireless carriers for sharing location data
Everything should be opt-in. Burden should be on them, something like, "We want to share your data and if you agree here are the benefits to you."
idatum··on Ask HN: What have you built with ESPHome, ESP8266 or similar hardware
Battery powered home front gate sensor using an ESP-01s and MQTT.

It's simple and I'm impressed that a single CR123A battery has lasted now 7+ months and still reading >= 3.1V.

idatum··on Space-Track.org
As of Tuesday, 23 April 2024, to reduce confusion and improve performance for all users, API limits/thresholds will be standardized across all endpoints to "Limit API queries to less than 30 requests per minute / 300 requests per hour".
idatum··on M 4.8 – 2024 Whitehouse Station, New Jersey Earthquake
Everything gets amplified on the East coast, any event, since much of the media we consume originates there.

The PNW does get tremendously powerful Pacific cyclones every so often [0]. These are huge storms that would do real damage to mid-Atlantic cities.

And there's the known risk of the "big one" -- subduction zone quake, Seattle fault, etc. Sleep tight East coast, you'll be fine.

idatum··on Google agrees to delete private browsing data to settle Incognito mode lawsuit
My hope is these cases force more users to better understand how our data is collected and monetized, without our consent.

The "I've nothing to hide" attitude might start being overshadowed by "Wait, they are collecting what? And making billions?"

idatum··on NetBSD 10.0 Released
Awesome news!

I've been running a few versions of the RCs for NetBSD 10 on a Pine RockPro64. A few reasons NetBSD 10 is a good choice for this Aarch64 device:

- Handles ARM's big.LITTLE well. You can use /usr/sbin/schedctl -A 4,5 to pin a process to the fast cores.

- Generally rock solid -- I've had uptimes in months and generally only rebooted when I upgraded. Like today!

- Can boot from an eMMC instead of an SD card.

- Supports the PCIe card. I have an SSD adapter. You can even use ZFS.

- HDMI support.

idatum··on Running a Raspberry Pi with a read-only root filesystem
These Pi* devices have served well running their Debian version for years.

I had a Pi3b run ADS-B (generally RTL-SDR) for many years. Dang though, all with (seemingly) random SD storage failures. Article details seems like it can help.

There are more options now though. Aarch64 ones that use eMMC.

I replaced the Pi3b with a Pine64 Rock64 running FreeBSD 14 booting from eMMC. Simple and just works with all RTL-SDR needs covered.

It's great to have options, both hw and os.

idatum··on Northern lights forecasted to be visible into upper United States tonight
I expect more from NOAA getting "tonight's" and "tomorrow night's" more clearly communicated on their site using UTC. Not sure that site's graphic uses my browser locale.
idatum··on YouTube now requires to label their realistic-looking videos made using AI
> Altering footage of real events or places: Such as making it appear as if a real building caught fire, or altering a real cityscape to make it appear different than in reality.

What about the picture you see before clicking on the actual video? This article of course is addressing the content of the videos, but I can't help but look at the comically cartoonish, overly dramatic -- clickbait -- picture preview of the video.

For example, there is a video about a tornado that passed close to a content author and the author posts video captured by their phone. In the preview image, you see the author "literally getting sucked into a tornado". Is that "altered and synthetic content"?

idatum··on Home Lab Beginners guide
In the spirit of "your setup, should be your setup. As traditional or as custom as you’d like!" as mentioned in article, I went with a vertical mount rack. It's not enclosed so it has enough ventilation.

The advantage with a vertical rack for me was space savings. Key parts of my home lab are near the low voltage panel (lucky to have in newer house) which does have foot traffic from other household members. Much less risk of someone bumping into the rack.

idatum··on How do computers calculate sine?
I just recently came across CORDIC in a fun read I just finished, 'Empire of the Sum', by Keith Houston. It's a history of calculators, and there's a chapter on the HP-35 which used CORDIC. The author goes into some details how it was used by that constrained device.

There are a lot of references given in the book including more details on CORDIC.

idatum··on OpenAI and Elon Musk
> We realized building AGI will require far more resources than we’d initially imagined

So the AGI existential threat to humanity has diminished?

idatum··on Microsoft is ending support for the Windows Subsystem for Android (WSA)
I have Android and I can turn off notifications. This is my default except for Signal which my immediate family is on (they call on it too).

SMS is mostly SPAM, so definitely off. I would never pick up a call originating from my carrier.

For your scenario:

Do the same for all notifications, and only check phone when you want to, when home?

idatum··on Where is all of the Fediverse?
Mastodon using a local instance (not mentioned) has been good in my experience so far. I've had fun and useful technical exchanges, as well as healthy general random chats. I think I've been able to control what is in my "feed" well enough. So far.

I do not think Mastodon (or especially Lemmy) are immune to the outrage culture of X and the like.

My guess: More growth ahead for the Fediverse, outside of areas discussed, and it will degrade rapidly.

idatum··on Google helped destroy adoption of RSS feeds (2023)
Once I fully embraced the fact that Google is an ad company -- not a software company -- their behavior doesn't pique my interest anymore. I don't rely on any of their software or services.

But I wish generally they would stop hoovering up and monetizing my personal data. F'ckers.

idatum··on Keep your phone number private with Signal usernames
I just don't want my metadata (contact graph) hoovered because I send a (encrypted) message to someone that may be an over sharer on FB, etc.

I use Signal because I am a "nothing to hide and I like to own my privacy as much as possible" type online person.

Signal == more peace of mind just generally in this online world we have.

idatum··on Speak Friend and Enter – Do people use movie passwords? (2018)
Not passwords but used movie references to name my machines on the corporate network. Pretty sure my "TMA-1" build machine was unique.
idatum··on Thinking Forth: A Language and Philosophy for Solving Problems (2004) [pdf]
> A REPL into your hardware!

This is what got me interested in Forth using ARM STM32 devices a couple years ago.

Specifically, I put Mecrisp-Stellaris Forth on an STM32F401. It was fun! You can experiment and quickly learn (fail fast) trying different features -- could try features of the chip as I read the datasheet.

I was able to translate those learnings to a C implementation as well.

idatum··on AdGuard Home: Network-wide ad- and tracker-blocking DNS server
If I recall, I was inspired by this:

https://www.tumfatig.net/2022/ads-blocking-with-openbsd-unbo...

idatum··on AdGuard Home: Network-wide ad- and tracker-blocking DNS server
I ran Pi-hole along with my OpenBSD router running unbound for some period. Then I realized I can download the same entries used for Pi-hole, AdGuard, uBlock, etc. I created a simple script that generates an unbound configuration that I can include in my unbound.conf file.

One advantage over Pi-hole I noticed is I can return NXDOMAIN which makes more sense to me. I didn't see how I had that option with Pi-hole.

I just checked, and the generated unbound configuration comes in at 218000 lines, so takes a moment on my Celeron J3060 class router when loading unbound.

idatum··on AWS charge for using IPv4 expected to bring $1B/year and speed up IPv6 adoption
For my ISP, it's not just about the hardware, it's their provisioning software that needed replacing. It has to be simple for their support to understand how IPv6 is given to customers.
idatum··on Comcast reluctantly agrees to stop its misleading "10G Network" claims
You should push to have fiber. Once you get 1gb symmetrical (in my fortunate case after moving), there is no going back.

Not-fond memories of getting through to Crapcast support to resolve outage (e.g. cable laid in 90s failed) and then being pitched a "a great deal just for you" of "upgrading" to get catv sh*t package, as I waited.

Damn though, Crapcast did get to IPv6 fast and that specifically was solid in my previous house.

idatum··on 23andMe's Fall
Reminder of the film Gattaca which explored some of the risks of leaking your DNA in a future dystopia.
idatum··on Researchers have found a faster way to do integer linear programming
I wish I can remember how I even learned LP tools existed. I started with this: https://coin-or.github.io/pulp/
idatum··on Researchers have found a faster way to do integer linear programming
I only recently learned about linear programming. I started with PuLP and Python to get a grasp. It was one of those "How did I miss this??" moments as a developer.
idatum··on Confirmation of ancient lake on Mars
> Or perhaps we'll keep searching for a thousand years and never find a trace beyond Earth.

If we find evidence of current/past life on Mars, what is the math that this means there's "overflowing" life throughout the universe?

And of course, the inverse: If there is no evidence on Mars, what does this show whether there is no current/former life outside the inner solar system (besides Earth)?

Maybe we spend less on Mars (at least for now)? So much more out there than ancient lakes?

idatum··on Try to make sudo less vulnerable to Rowhammer attacks
doas.conf makes things clear to me what I'm enabling.

And we have the OpenBSD folks focused on clarity and security.

idatum··on Are we past peak IPv4?
IPv6 does allow you to have a client on any ISP to not rely on IPv4: NAT64/DNS64 is one example for a home network (my experience). There are major mobile carriers that will also disagree, and they provide an IPv6-only technical solution.

> It's hard to estimate how increasing percentage of users with IPv6 access is impacting the demand for public IPv4 addresses.

I'm more interested in this excellent point you make, about the economics. I don't think this has been thought through as well as the technology.

And can we please find additional sources other than GOOG for IPv6 adoption?
