buildbot··on Ask ChatGPT to pick a number from 1-10000, it generally selects from 7200-7500
I asked my little Claude Code API tool, it answered 42 then it (the API) decided to run bash and get a real random number?

'>cs gib random number

Here's a random number for you:

42

Just kidding — let me actually generate a proper random one: Your random number is: 14,861

Want a different range, more numbers, or something specific? Just say the word!'

Just poor ones - how much could it cost to get a scan of the oceans once weekly or daily? 10 million dollars?

Which to me is a really good, encouraging thing.

Overall I feel safer in a Waymo than a rideshare now and I only spent a few days being able to use Waymo...

Literally some of the highest dynamic range sensors attached to probably the best generally intelligent model existing we know of -

Humans are hard to compete with! I'd want LIDAR & RADAR just to give me an edge.

I guess in some ways even the fancy multi diode fiber lasers are phased arrays, just with the single goal of higher output power.

You could possibly infer an estimate of base staff based on that info; not like a great number, but a number.

Ah; if only this was really true. You can certainly get a computer into a permanently bricked state, especially an embedded device. Even a modern x86 machine can be basically toasted by a bad firmware update.

I had exactly the same thought, and was quite intrigued. Very disappointed actually, it would be cool if there was open data about land mines.

buildbot··on A review of M Disc archival capability with long term testing results (2016)
Yeah, with you 100% here. It's all about the volume and use case.
buildbot··on A review of M Disc archival capability with long term testing results (2016)
Really the one thing that's guaranteed to be manufactured in N years is _some kind of storage_. I wouldn't buy LTO-1 now, but later gens are going to be around for some time, just like CD-ROMs and other optical media, in some form. And readers will always exist barring an asteroid impact or whatever.

>Therefore I already know the answer on whether I could possibly buy newly manufactured LTO drives and media in 10,20 years, and it starts with a NO. Even today I would be forced to buy second-hand drives. Why would I even entertain LTO as an option, then?

You can still buy brand new LTO-1 media from 2000 - 26 years old. You shouldn't, but you can. https://www.malelo.com/Maxell_LTO_1_Ultrium_Tape_100_200GB_1... Then here's a cheap drive https://www.ebay.com/itm/355784908408

So if you needed to restore a backup from 26 years ago, it would not cost you very much.

buildbot··on A review of M Disc archival capability with long term testing results (2016)
I'm confused - I and many others basically have these cobbled together LTO setups. I'm only "Prepping" by finally moving some of my backups away from home, so in case of a fire or whatever I'm not out of luck. You could cobble one together now for anything from OG DAT tape to LTO-10 for ~10K, if you need. So big fire happens, you file an insurance claim, and as part of the payout buy whatever setup you need, or hire some specialists. Once we are at LTO-20, there's no reason to assume LTO-10 and older drives are totally gone from the used market?

I'm not preparing for some asteroid impact level event, in that case the loss of my backups will presumably not really matter all that much.

I bought a thunderbolt to FC adapter; works perfectly on Mac and Linux.

I mention LTO 4 because you can today, buy multi decades old LTO-4. Brand new. So in multiple decades from now, I assume you’ll be able to find LTO-7 or 8; brand new. A drive might cost a little more to obtain, but given the plethora of used multi decades old lto currently out there, it seems reasonable to expect that in a recovery scenario you’ll be able to shell out for the right drive.

But yes for most HDDs or the cloud are better. No need to get spicy about it.

This is true - I got a fiber channel LTO-8 FH drive off ebay brand new in the IBM packaging for less than 750$ Tapes are 60; so breaking even against 15$ per TB HDDs is pretty fast.

I believe they are all 5.25in, some are just in a case. Even the library drives are just two 5.25 bays put together, a full height drive; vs. the much more common half height.

You can still buy brand new LTO-4 and up from a brief search - I think due to the enterprise use cases it’ll hang around longer than any other format. Tape existed before the HDD; it’ll be there watching HDDS pass away into the ether too. Probably a few tape drives on the Starship Enterprise somewhere.

More seriously; you can buy used lto-7/8 for very little these days, and the tapes are extremely cheap per gb. The drives are somewhat loud; it’s not a beside device for sure. I’m finding it a bit of a pain to manage a good backup strategy with them.

In that case we must go deeper, and analyze the number of comments on articles on articles about the singularity.

buildbot··on Disruption with Some GitHub Services
“We believe we have found the cause of the problem and are working on mitigation.” Wow - they believe they’ve found it! Comforting.

Having worked at Microsoft in the recent past I’m not surprised everything is starting to fall over a lot more.

While there are tons of good people at Microsoft, the overall culture and number of people who stand in the way of getting stuff done well is immense. People view you or your team doing work as an existential threat to their team, and react accordingly.

I don’t think the recent uptick in failures is related to vibe coding or AI and has everything to do with the corporate culture. Probably some poor product manager was tasked with closing 10k automated security flags/tickets and in doing so broke some load bearing microservice that depended on a kind of service principal that’s now not allowed.

Interesting and makes sense! I know nothing but what I read from the stain description haha. OsO4 seems incredibly nasty. So do a few other of the stains!
buildbot··on Reliable 25 Gigabit Ethernet via Thunderbolt
That’s a good point to note! I think the stacking height would matter, but in theory the single connector is still 8x pcie and should link without the upper 8x lanes connected.

Spec for reference, I’m not 100% sure. https://docs.nvidia.com/nvidia-connectx-5-ethernet-adapter-c...

buildbot··on Coffee as a staining agent substitute in electron microscopy
Wow you know it’s a fun party when the first result needs to specify it’s _not_ radioactive

Oh I see - Uranyl Acetate is radioactive and this replaces it. Fun!

This seems like a friendly chemical too - “ The chemical properties of Osmium Tetroxide are such that use and handling of the chemical is often considered daunting. Although its volatility and toxicity certainly makes it a dangerous chemical, but when following the proper procedure and taking the necessary precautions, Osmium Tetroxide can be used to its full potential with limited risk to the user.

This is more toxic than glutaraldehyde and has a higher vapour pressure. Particular care must be taken to avoid breathing the vapour or allowing it to affect the eyes. ”

Yes, Kelvin is only a linear offset from Celsius. (273.15 for anyone who doesn’t already know).

It’s a little bit funny/coy to use it mixed with Celsius.
