idatum··on Maps distort how we see the world
Makes me wonder why South isn't intuitively "up" for folks in the Southern Hemisphere.
idatum··on Distcc: A fast, free distributed C/C++ compiler
Used distcc back in mid-2000s to crosscompile NetBSD kernel/userland for a TS-7200 SBC ARM device. Back then those devices didn't have much processing power, would have taken days otherwise.
idatum··on Alien was released 44 years ago today
Is it realistic to expend what should be a tremendous amount of energy to put a massive cargo space vessel in (presumably) an orbit around a planet? And then expend energy again to escape and head back? Memory fades, so most likely better explanation.
idatum··on Enabling IPv6 support for IPv4 only apps on Linux
OpenBSD, with PF and Unbound, has excellent NAT64/DNS64 support. Unfortunately, my ISP is still IPv4, but with HE tunnel broker I can at least experiment with an IPv6 only VLAN. Works great on all clients I tested: Windows, Debian, and *BSDs.

BTW, my ISP has been promising a /60 for many months now. Apparently, it's about their "provisioning software" they inherited. Huh, equipment less of a concern in this case.

idatum··on Termux is an Android terminal emulator and Linux environment app
The combination of termux and scrcpy is pretty cool. Scrcpy is currently being discussed as well: https://news.ycombinator.com/item?id=35749366

I have one of those Bluetooth keyboards and mice that allow multiple paired devices. There's a button on each to allow you to switch. That's pretty handy to have it paired with my old Android device and be able to pop over and use my tmux sessions.

idatum··on Thinking about our passive exposure to IPv6 issues
My fiber provider inherited network equipment that is preventing them from deploying IPv6. On their subreddit they responded from multiple inquiries that they are ready to provide a /60 once they upgrade their equipment.

I imagine this may be a problem for other providers.

Thankfully no CGNAT, so I have a couple VLANS that use he.net in the meantime.

idatum··on Displaying My Washing Machine's Remaining Time with Curl, Jq, and Pizauth
I use CT (current) sensors on the circuits for both washer and dryer and a small XBee ZigBee device using its ADC pins to transmit the current readings. On the server with an XBee coordinator, I use a moving average window to cover points where the washer or dryer use very little current. It's then pretty easy to detect on/off, and even where the current cycle is. The obligatory Home Assistant integration notifies household members.

Plotting the dryer data, you can see how it works. The heating element turns on for a period, then turns off and the humidity is most likely read at that point. The gap between periods of the heating element on increases, and the heating length of time decreases, until if stops spinning. Cool DIY project.

idatum··on When Slide Rules Ruled (2006) [pdf]
I have an HP-35 (previous owner bought it new) mentioned in the article as "the death knell for the slide rule". The rechargeable batteries are long since gone and one of these days I'll get motived and try to replace them. It has very satisfying buttons, kind of like how old IBM PC keyboards feel.

It came with a metal case with lock and key. You would bolt the case to your desk and lock it. At $395 in 1972, I can understand why.

idatum··on Disclosure: Supervisor security vulnerability
An SSH tunnel is my strategy as well. The only internet port I have open is an OpenBSD sshd with a low privilege chroot'd user, SSH key auth only.

I tunnel from my Android device using an SSH client app. The only port open to HA is localhost on the client.

idatum··on Disclosure: Supervisor security vulnerability
HA provided a fix and broadcast the security issue reasonably effectively. Here we are discussing on HN. Good.

The vulnerability boils down to having a port open to HA (direct or proxy) exposed to the internet, or if your LAN is already compromised.

Many HA users will make the upgrade. Some HA users will not upgrade. Perhaps those are locked into a specific version, maybe because of the various integrations that cause issues when upgrading, etc.

It's interesting now the trade-off between "local" and "cloud". Home automation generally has this tension right now. Users want access to their "local" HA instance from a coffee shop, say, but don't want to deal with privacy issues and security breaches of "cloud".

idatum··on LastPass: Security Incident Update and Recommended Actions (1st March 2023)
Still no details on how far those stolen vault backups went. I'd like to know which of my vault passwords over the years was included.

I've since switched to 1password and rotated every (damn) password. That was an entire weekend burned.

idatum··on LastPass says DevOps engineer’s hacked computer led to security breach in 2022
For anyone that had been deep in LastPass with passwords, I recently switched myself and convinced my family also. We switched to another [read recommendations] online centralized password manager. It takes a couple hours of your time-off; totally can stream some whatever show in the meantime to pass the time.

One benefit is that it made me audit my online accounts -- I removed many.

So: Be prepared to switch if you want this type of service. New normal.

idatum··on Sea life bounced back fast after the ‘mother of mass extinctions’
For those that took 'mother of mass extinctions' as click-bait, it refers to 'Permian–Triassic mass extinction'.

It's amazing how resilient life is once it takes hold.

idatum··on Bell Telephone launched a mobile phone during the 1940s
Or maybe like farmers using electrified barbed-wire fences to chat? Like Claude Shannon used in his youth! Came across this in a bio on Shannon I read recently. And here we are now.
idatum··on Has Earth’s inner core stopped its strange spin?
Science as a belief, not a process of learning?
idatum··on The Unreasonable Effectiveness of AWK
That literary effect works these days, unreasonably well unfortunately.

How about "AWK is Still Effective". I'd still click on that.

idatum··on Pi-hole: Network-wide ad blocking
Same. Windows devices and TVs on my network handle many NXDOMAIN responses to DNS requests :)
idatum··on What the hell is Forth? (2019)
I still use it when exploring a microcontroller, lately with Mecrisp-Stellaris Forth on an STM32 device. It's a joy to use.
idatum··on The cost of cheap TVs
At least it's encouraging we're seeing more and more articles and awareness of these data collection practices. I'm hopeful we'll reach enough outrage (always seems to need to come to that).

The last "smart" tv I purchased (Costco) is working fine without an internet connection. Pihole blocks much of the telemetry being sent from the attached XBox. XBox has a Hauppauge USB tuner with OTA antenna for when I want to catch a local sports broadcast, etc.

idatum··on The internet wants to be fragmented
> Years ago, I started thinking of the LIKE/UPVOTE button as an "increase visibility" button.

I think Mastodon tries to make that distinction with like vs boost. Boost seems to be about making a post more visible ("hey look at this!") and like is more about "thanks for posting". At least on the server I use.

idatum··on What are those dents in I-90 outside Seattle?
Only slightly related, about I-90 generally:

A parent of mine who grew up and lived most of their life on the East Coast, US, visited and we drove east across WA. At one point they could not wrap their head around the fact that we had been travelling at around 80 mph for 2 hours. And it basically looked the same out the window :)

The US West is huge.

idatum··on LastPass user vaults stolen in recent hack
LastPass is an enormous target, obviously. And, I guess, the inevitable has happened: Encrypted trove of passwords is "out there".

Let's assume one's master password is strong. And that LastPass knows how to encrypt data. We're really down to whether 256-bit AES can be brute forced, right? And I guess understanding phishing attacks.

I mean, yes, wouldn't it be great of LastPass took the measures with its development environment years ago? So put another way: Lack of operational excellence hopefully is made for in strong encryption. I hope.

idatum··on Getting Started with Tmux
For Windows users: Install Windows Terminal and enable WSL. WSL or WSL2 are both fine (I use both). I have like 10 tmux sessions going in 2 or 3 tabs. It's a whole new level of CLI on a Windows box. Loving it.
idatum··on An extensive tutorial on how to setup a Pi-Hole
I use both Pi-Hole on an RPI3 on a VLAN locked down for IoT devices, and OpenBSD + unbound(8) on my default network.

Both options are great, and OpenBSD/unbound has been running just as easily. Here is a recent HN thread on this: https://news.ycombinator.com/item?id=33122419

idatum··on CPSC calls for full recall of all Onewheel self-balancing electric skateboards
My inner twenty-something and my not-twenty-something body will benefit from a report like this. I'm still reasonably athletic and those things look dang cool, but the pause a report like this gives is healthy.

I also agree with other comments related to motorized bicycles. I wear motorcycle gear even when riding locally and under 40 mph. Electric bikers can benefit from "gearing up".

idatum··on The fall of Sam Bankman-Fried is crypto’s Enron moment
> SBF describes coins like a ponzi with no shame https://www.youtube.com/watch?v=C6nAxiym9oc

Just offering that just a few minutes into that video, I saw everything I hate about many youtubers' style, generally. I can't describe it, but there it is.

I listen to Odd Lots. Generally, that podcast keeps things thoughtfully presented. I remember that episode and it reinforced distrust of crypto.

idatum··on QNX DEMO disk (1999)
There was a time before this article when I put QNX on an old iPAQ Pocket PC. Back then (mid 2000s) it was strange to see a Unix OS running on a handheld device!

EDIT: I think I found a link for it:

idatum··on Google Broke Image Search for Creative Commons
> my Google-fu is strong

Initially read this as, well, "FU Google", and thought "yep, FU to them too". I guess I will acknowledge I have a bias. Then curious about this term, I googled-on-bing "FU Google". Top result was Google-fu, not the expletive.

I have no Google-fu.

idatum··on Fitbit users will have to sign into Google from 2023
Is there a workout tracking, watch form factor, device that does not require "cloud" in any way?

I want the convenience of a watch to track my workouts without a single thought that GOOG et al can collect. I want to download it to a local device and analyze it there.

And I don't care if GOOG is "99.999999999%" better at protecting my data. The point is I do not want them to have my data.

idatum··on Ask HN: Recommendations for ‘minimalist’ (e.g. not too ‘smart’) phones?
I also take this approach with a low-end Pixel. Only a Signal message or call notifies.

No social media apps also key.
