bob778··on Data centers contain 90% crap data
There’s a whole concept of records management in enterprises that manages the disposal of data. It’s far more complex than just purge dates as there’s often regulatory requirements and legal discovery issues so <2% of data is actually disposed due to perceived risk.

For personal data, the concept would be simpler but still has requirements like say tax records need to be kept 7 years.

bob778··on Exploring Alternatives to UUIDv4; Enter ULIDs
They didn’t want to make a breaking change but didn’t:

1. Use UUIDv7, which has the same sortability without breaking the ID format, or

2. Repackage the ULIDs to maintain consistency

And then broke pagination with this change?

How was this ever approved by a change control board? Or do they not have one?

bob778··on Show HN: Documind – Open-source AI tool to turn documents into structured data
From just reading the README, the example is not valid JSON. Is that intentional?

Otherwise it seems like a prompt building tool, or am I missing something here?

bob778··on Ask HN: What is the most useless project you have worked on?
There’s so many countries this could be: Australia, USA, UK, Italy, Estonia.. it’s almost a national pass time
bob778··on Spreadsheet "breaks" Apple Vision Pro eye-tracking
Native Australian English speaker here: I would 100% interpret that as they camped on the beach because that’s an option at some places here. Goes to show how it’s cultural I guess.
bob778··on Japan ANA Boeing 737-800 flight turns back due to cockpit window crack
No, it is a variant of the 737 so using the certification is correct. They weren’t trying to avoid additional certification, it just wasn’t required as it’s a variation of an existing type
bob778··on Real-world ranges for Teslas 50-60% of EPA Range
Most ICE cars show remaining fuel as a distance now, in addition to the fuel gauge (although some now hide the gauge behind several digital menus). No GPS required though, just a tachometer and fuel-burn sensor, and they're required to be accurate to within 2% by law.
bob778··on OpenTF announces fork of Terraform
They did layoffs about 2 weeks before the licence change.
bob778··on A retiring consultant’s advice on consultants
That’s the difference between management consulting and technical/expert consulting. Expert consulting is for spinning up CRMs or installing SAP, management consulting is far more vague and strategy level.

Some of the big firms have started mixing the terms up because they can charge more that way.

bob778··on Some problems with 'first name' and 'last name' fields in data
What standard allows multiple aliases on one passport?

AFAIK, the MRZ and chip don’t support alias fields?

bob778··on Hacker mods an M1 Mac mini to receive power over Ethernet instead of AC
That should only be possible if using non-standard "passive" PoE?

802.3bt has negotiation specifically to prevent faulty cables/devices from being powered.

bob778··on NASA mistakenly severs communication to Voyager 2
In the general category of “most powerful radio transmitter”, it doesn’t even rank in the top 5. The biggest are 1MW+.

Many industrial sites use 450kW or more (see any bauxite processing plant) so are coupled with a power plant or have agreements for dedicated generation at nearby plants.

bob778··on NASA mistakenly severs communication to Voyager 2
There are absolutely very well-defined and detailed standards for cars defined at both a national and international level. They range from excruciating requirements around single components (eg. ESC) through to broad design requirements (like how wide a car).

See the Australian Design Rules (which happens to form the basis of most UNECE and Canadian transport regulations) if you want to see how detailed they are.

bob778··on Arc Browser 1.0
I’ve worked on projects that logged locally and only transmitted every ~60 days when they detected the right network (eg public wifi). So unless you monitor it continuously and permanently this isn’t true.
bob778··on Thunderbird 115 “Supernova”
Why does this website look almost identical to the Owl website below?

edit: Same pricing, same exact signup form and "Domain Licenses" page, etc. but way worse design. I'm guessing this is a knock-off of Owl? Or worse?

bob778··on Debris found came from missing Titan sub, says friend of passengers
Boeing denies any involvement while the University of Washington says they briefly worked together on a completely different unmanned vehicle
bob778··on Titanic tourist submersible goes missing with search under way
In submersible tech, just beneath the surface is 0-30m depth basically (for salt water). Cellphones signals are about 2m max while higher frequencies (eg 2.4GHz) drop off exponentially so are <1m
bob778··on Google keeps failing its Nest customers
To add to this: the Nest Protect isn’t compliant with Australian, NZ, or some EU countries standards due to it using single-insulated wires and not being compatible with hard-wired interconnects. This has been a problem for 6 years and most licensed electricians refuse to install them, but they just keep selling it? (I’m not actually sure if it’s even legal to sell it technically?)
bob778··on WebContainer API
Site is blocked due to “active security threat” so that’s not a good sign for an enterprise SaaS
bob778··on How do you know when macOS detects and remediates malware?
So at least 0.25% of the fluent speakers were involved in translating it, possibly more
bob778··on Tesla Vision Update: Replacing Ultrasonic Sensors with Tesla Vision
As an insider of the automated manufacturing space, your ERP analogy is good but missing one detail: every other large company eventually gets an ERP working. Tesla is an outlier in regard to their manufacturing processes and even much lower margin industries tend to design new factories around the automation platform yet Tesla just...doesn't?

I've never worked with Tesla so have no inside info on their situation but their factory designs have always seemed strange to me - like they refuse to follow industry norms.

bob778··on Github.com Down Again?
It’s still intermittently down and most CI jobs are failing with network or authentication errors. A bit disappointing that the status page makes no mention of this.

It was also giving 500 errors about 14 hours ago for 30 mins and went undocumented

bob778··on Australia ranked 61/63 countries for entrepreneurship
It’s worth noting many of these metrics are measuring the quality 4-5 years ago, and I think its improving relatively quickly.

That said, the quality of internet is such a silly metric. Almost all places, including rural Australia, have better than 25/15 with metro areas having fiber due to the NBN rollout. That really is not our limiting factor - our culture and generally small funding amounts is.

bob778··on Australia ranked 61/63 countries for entrepreneurship
Almost 95% of Sydney has fiber thanks to the NBN? (FTTN or better)
bob778··on Docker is dead? Podman – an alternative tool?
From using podman in prod, it seems to be lots of features but not necessarily stable or well-rounded
bob778··on Docker is dead? Podman – an alternative tool?
Podman always feel like software no one’s using in prod. There’s a lot of edge cases and bugs - particularly in the service control, user groups and ipv6 support
bob778··on Hackers claim to have breached Okta systems
It appears they’ve had access since at least January. I wonder how many customer accounts have been breached? It’s a giant list of targets if so.

It’s also very disappointing this is surfacing via tweets and not a breach notice from Okta, who apparently suspended at least one account used for entry.

bob778··on Things I Won't Work With: Dioxygen Difluoride (2010)
I think the pint is that it’s clearly a fake listing as no one could safely handle 1kg of the stuff.
bob778··on Running IntelliJ Idea with JDK 17 for Better Render Performance with Metal
They literally broke all plug-ins for months because of a regression in stripping white space from config files. The whole product is incredibly poorly tested and is only dominant because it’s the least terrible.
bob778··on Six dead after tornadoes destroy Amazon warehouse near St Louis
FYI, fire alarms are designed to become more sensitive as they age/die so if yours is picking up false positives, it’s a good indicator you need to replace it. That, or it really is poor ventilation.
