aaronax··on Microfeatures I love in blogs and personal websites
There is a "back-channel" way for most sites: sitemap.xml

Many sites have it, since it is helpful for SEO. Examples:

https://www.1500days.com/sitemap.xml (Wordpress) https://dri.es/sitemap.xml (Drupal, illegible though) https://aaron.axvigs.com/sitemap.xml (Drupal, legible)

aaronax··on Nobody knows what's going on
Normally yes, but I think an exception is allowed in this case due to the irony of the person being oblivious to an article talking about people being oblivious.
aaronax··on Nobody knows what's going on
Mind boggling. Though now I know that for all HN commenters, truly "nobody knows what's going on" (in the article).
aaronax··on From One RSS Feed Entry to 186850 Hits
Speaking of RSS, and this feed specifically, it is the only one (of hundreds that I subscribe to) that periodically spams a set of old posts into my "fresh" feed. Some backend change that causes unique identifiers or something to change?

TT-RSS is my client.

aaronax··on Decade of the Battery
What's the go to rack mount inverter charger to go along with that? Asking for a friend...who only needs about 800 watts of capacity to act as the certified hacker version of a UPS. I've only done Victron stuff in the past, and those are not rackmount nor is there a 48V in 120V out model of less than 3000VA capacity.
aaronax··on I organized a 20-acre game of Capture the Flag
Same vibes for https://en.m.wikipedia.org/wiki/SubSpace_(video_game) I reckon.
aaronax··on The Rise and Fall of the Trad Wife
Strong. The US is full of vibrant 100k population cities.
aaronax··on The Rise and Fall of the Trad Wife
Myself and my three siblings all have young and growing families with stay-at-home moms. Incomes ranging from 80k to 200k (guessing some), fairly LCOL in North Dakota. Most of the parents involved are what may best be summed up as "good with money" but not crazy wealthy, more like work hard / save hard / be wise, and set their children up well for success. We went to state colleges and have practical degrees: engineering, biology, business, and education.
aaronax··on NPR suspends veteran editor as it grapples with his public criticism
Yes

I have started reading the piece by Uri now and it basically confirms what I was imagining.

"He declared that diversity—on our staff and in our audience—was the overriding mission"

"Journalists were required to ask everyone we interviewed their race, gender, and ethnicity (among other questions), and had to enter it in a centralized tracking system."

Pretty much guaranteed that they were trying to hit race/gender quotas.

aaronax··on NPR suspends veteran editor as it grapples with his public criticism
Images of what I imagine to be their yearly performance goals rush through my head as soon as it turns to victim, race, oppression, etc.

"25% of stories uplifting Black voices" etc.

It just seems so forced.

aaronax··on Learning about distributed systems: where to start? (2020)
It takes a big gun/bullet to hunt a bear, so you're well prepared aka "have the big guns out".
aaronax··on Show HN: Building a GPS receiver
Related: Satellite-based augmentation system (SBAS), of which Wide Area Augmentation System (WAAS) is the USA implementation.

aaronax··on St. Louis Brick by Brick (2023)
From the context, it seems you mean repointing, not tuckpointing. (As described in the Wikipedia article you link, which admittedly does make an allowance for some regions using the terms interchangeably.)

But, the true meaning of tuckpointing (two-toned bands of grout to give the appearance of finer grout lines) is something I did not know about and found pretty interesting. Thank you for the comment.

aaronax··on Terraform makes carbon neutral natural gas
30x strong on what measurement? Per molecule?

How much CO2 is Terraform Industries pulling from the atmosphere to create that 4% of methane that might be leaking?

aaronax··on Error Handling in Baby Toys
I also recently analyzed the binary encoding of a baby toy.

aaronax··on Real-time map of every Starlink satellite in orbit
I prefer https://satellitemap.space/

You can see the base station locations there, which is helpful in visualizing how the system works in various locales.

aaronax··on Hackers found a way to open any of 3M hotel keycard locks
Same as basically any physical lock can be trivially picked. Yet no one is buying office door locks based on pick-resistance. Burglars will smash their way in anyways.
aaronax··on Airlines Colluded to Ensure Onboard Food Would Be Awful
Yes ("premium"), between Chevrolet and Cadillac.
aaronax··on Vehicle brakes produce charged particles that may harm public health: study
I do the same in ICE cars with automatic transmissions and it seems just fine. I think the torque converter handles the opposition elegantly.
aaronax··on Home Lab Beginners guide
And a huge win that it makes it so easy to have distributed storage. Ceph is built-in and works well. Being able to add disks as needed is bliss (no RAID planning up front). And the rebuild situation is better than any RAID. Performance is adequate for homelab even on a 1gbps network. I have about 10 SSDs mixed 1TB and 2TB across 5 hosts (old Optiplex units).
aaronax··on A daddy-longlegs possesses six eyes, including two vestigial pairs
Back in the flip phone days some people had little dongles hanging from their antennas that would light up seconds before the text chime went off. I guess it sensed the incoming transmission?
aaronax··on Bob Moore, who founded Bob's Red Mill, has died
I don't think that is possible. How would you own shares in multiple companies where the shares are owned (exclusively? mostly?) by employees?

Any mechanism which facilitates outside ownership erodes the effect of being ESOP.

aaronax··on I'm Done Punching Trees and Grabbing Rocks in Video Games
Better to build a garage, plant a row of trees, or steward a community organization. Something that you can show your kids and be proud of. Open source software work even.

Some entertainment being necessary, I feel the vast majority of people do it too much.

aaronax··on Ceph: A Journey to 1 TiB/s
I just set up a three-node Proxmox+Ceph cluster a few weeks ago. Three Optiplex desktops 7040, 3060, and 7060 and 4x SSDs of 1TB and 2TB mix (was 5 until I noticed one of my scavenged SSDs was failed). Single 1gbps network on each so I am seeing 30-120MB/s disk performance depending on things. I think in a few months I will upgrade to 10gbps for about $400.

I'm about 1/2 through the process of moving my 15 virtual machines over. It is a little slow but tolerable. Not having to decide on RAIDs or a NAS ahead of time is amazing. I can throw disks and nodes at it whenever.

aaronax··on Ceph: A Journey to 1 TiB/s
Yes. Most network switches can handle all ports at 100% utilization in both directions simultaneously.

Take for example the Mellanox SX6790 available for less than $100 on eBay. It has 36 56gbps ports. 36 * 2 * 56 = 4032gbps and it is stated to have a switching capacity of 4.032Tbps.

Edit: I guess you are asking how one would possibly sip 1TiB/s of data into a given client. You would need multiple clients spread across several switches to generate such load. Or maybe some freaky link aggregation. 10x 800gbps links for your client, plus at least 10x 800gbps links out to the servers.

aaronax··on The Naz.API Credential Stuffing List
It is only tens of gigabytes, no need for fiber to handle this. The 37GB of files can be downloaded in 1 hour on an 83mbps link.

(1gbps is 450GB/hour, useful for estimating things)

aaronax··on A drought has forced authorities to further slash traffic in Panama Canal
On the Falkirk Wheel you don't have to deal with weight differences at all, regardless of the size of the ship. The ship displaces a weight of water equal to the weight of the ship. So when filled to the same level, a side with water and a side with ship+water will balance each other perfectly.
aaronax··on I built an offline smart home
I thought the limited history was weird too and had bumped up my retention to 1000 days or something. Fortunately I only got a couple hundred days into that before they released just recently an update that includes trends in the history graphs. Apparently that data was there all along, just not being shown. It is not full data but enough to fill in the graph.

Just thought I would mention it.

aaronax··on The drive stats of Backblaze storage pods
You get two VARs, one with Dell and one with HP. Then a couple back and forth negotiation rounds and you will be paying 40-50% of MSRP. Or even try to do it direct with your Dell/HP reps, since VARs are of dubious value.
