Well, there are two big equivalents here: One, Uber successfully lobbied cities (NYC DeBlasio comes to mind, but there was one in London) - getting to a scale before meaningful enforcement action (which sometimes means investors maintaining their trust in the team, and the team sticking through the lawsuits) usually means you now have a customer base that is of voting age, and can substantially impact politics.

Two, Chevron deference is over. This is linked somewhat to the first - the overreach of federal agencies is now judicially balanced against the economic impact, not merely presumed authorized by Congress. Under this SCOTUS it is relatively uncertain which way FDA's authority will be curtailed - people will try, the fact that FDA wants to regulate the sale of non-invasive diagnostic equipment and mobile apps.. does warrant review and political discussion.

This is even more interesting (full disclosure - I vibecoded a lib for it lately - lowzag) when you take into consideration working set restrictions.

In almost every case, downscaling-while-decoding is going to beat decode-then-scale on performance - merely keeping the uncompressed image in RAM is going to cost you, when you can scale it down in L1 or even vector registers.

I'm actually curious if nowadays some ML-based algorithms are not beating Lanczos 3-lobe to it - at least in perceptual quality of the downscale. The have /long/ surpassed it in upscaling.

Well, where? I live in MA, lived in NH and visited MSP quite frequently, also spent a winter in Toronto… but even a quick search suggests that in MN it “dips” to negatives Fahrenheit, occasionally, with monthly Jan averages in low single digits.

Most of inhabited Canada is a thin sliver by the US border, or coastal which stabilizes the temperature around freezing quite well. Ditto with Norway.

Can you share a good example of a large (say 500k+ metro area, the “commonly”) city that actually dips below 0F daytime regularly? Murmansk comes to mind.. maybe..

Because gallon of fuel weighs 6lbs!

As a scientist and an adult immigrant to the US, I came to appreciate both systems as useful for different objectives.

Celsius/Metric is neatly rooted in science - where it truly shines by removing /most/ of the conversion factors (but does it? we still have, today, speed of light that should be 1, Avogadro and Boltzmann constants are just odd numbers you memorize too) - but doesn't match neither everyday weather and life (0F being "coldest you'll experience in a place humans commonly live" and 100F being "hotest", and close to wet bulb temperature and, through a fluke of an undiagnosed fever of Fahrenheits' wife, nice threshold for fever).

Fahrenheit/Imperial is actually relatively convenient to machining, industry and agriculture (but not engineering or science) - how much of that is actually fractional measurements (1/16th makes a ton more sense than 0.0625), and how much are the "fingertip/decent meal/daily water intake/sustains a person" idea of an inch/lb/gal/acre.. is quite intuitive. Far more so for composite units. 1 PSI is intuitive - you know what force to exert at what area of a piston, same for torque'ing to 80 lbs-ft.

But.. it makes a ton less sense when you separate N from kg (yeah, I am a physicist, I know why, it just makes less sense when building stuff in a dirty corner of an industrial revolution), then somehow apply it to a whole square meter to get a Pascal, and now you need decimal fractions of a million of those.. to represent what you actually see. Quick, do you think you can plug a 2cm diameter garden hose at 0.5MPa with your thumb to spray your dog?

CGS system was quite popular and useful, IMHO for that reason, at the time when Europe was actually manufacturing stuff and inventing them in barns and factories. But it was essentially "neither" - bastardization of sacred kg and meter - lost to SI.

US keeps inventing and making stuff in garages and fields.. and it shows in its devotion to imperial system. But I can see convincing mechanics to 1/8th of a cm and 40g way before I can see them taking up 1.25 mm and 0.04 kg.

ATSC. Technically orginal RTL tuners handled both (in really thin gateware, which is why the chip was so hackable for SDR, you just turned its debug mode and it would stream its IQ values).

Well, the reality of those types of businesses is that once set they do become a relatively low maintenance (and for some, very low 'urgent' maintenance) passive income.

It's really easy to pull $300k/y as an SRE (but that does amount to about $100/hr equivalent in SMB, assuming realistic >40h workweeks and the tax advantages in SMB, even less if you have to pay for services you enjoy and can't find time for due to FTE - nannies or even changing your own oil).

It is extremely hard to keep that $100/hr and a sliding scale - one week you work 50h, the other 30h, then you take a month or three off at $5h/week.

Mine (and I don't regret these) is running midsize PV plants. Slightly bigger than residential (hey, does OP want solar PV on the rooftop? I have a bowling alley as a client, they are a great match), but again not large enough to attract a scaled business.

I approximately put in 5h on each a year after the initial setup (around 100hr each), for $10k/y in profit from each.

Probably was that way before we got married and had a kid. And before our dog started getting older and we needed to watch what she eats.

Now the notion of "cook fresh every day" is a thing (rather than reheats), we try to do keep leftovers but eventually we run out of space for them.

1.5lb / day? I'd wager it's quite equally in thirds, would love to see the data.

I'd believe 0.5lbs/day/person in my household - cook enough for everyone to have seconds, but most of the time it's tossed (sometimes after some time spent in the fridge/freezer hoping for a reheat); stuff bought but inedible (chicken bones, etc)..

I'd believe similar in the distribution pipeline (just look at how much stuff are in the discounted aisle just about to fall off sell-by date + obviously moldy goods), and I'd believe similar in the production pipeline.

It certainly does, I mentioned it in an comment below, good callout.

I am however also more interested in how this affects other types of consumer behavior - and whether that is a factor in pullback on the economy (on top of other factors - energy, job market, trade restrictions).

Yeah - powerful confounder to all the analyses of customer behavior. Even the article itself calls it out - there probably is a good way to segment it, as GLP1 availability is not uniform, some states regulate it more tightly etc.

Or.. is it a GLP-1 byproduct? These are powerful appetite suppressants.. in fact I'm curious if the mechanism of action of these peptides affects other impulse behavior, including impulse purchasing?

We know that people buy more when they are hungry. They also buy more when the smells of food are in the store (the other benefit of rotisserie chicken).

Lol. Full circle.

RTL-SDR was originally the DVB-T tuner, hacked for SDR, to become.. a DVB-T tuner.

Great job!

Well, if they actually did a semi-decent comparison table, it would be easier.

It's a very crowded, relatively low barrier to entry, high barrier to switch space.

How does it compare to Mattermost?

Nice! I’ve dabbled with something similar on my own lately (originally wrote/vibed to explain some concepts that came up when discussing D&D) at diceplots.com - different approach, keeping the distributions exactly analytical at every step, never sampling.

I’ve been in this profession for two decades as well. As both things.

My take on this is that we need both, because the market is cyclical. It’s just that it’s hard to perceive any of those cycles if you (a) live them (b) are not experienced enough to introspect.

I absolutely would love an obsessed plumber (and got one!) when it comes to deciding that we’re going to do PTFE tubing in our new house. An obsessed electrician in charge to overinvest into our grid, rather than a 3-month timeframe executive. Otherwise our critical infrastructure gets myopically degraded.

I also want the “working within timeframe” outcome.

And we, as an industry, swing wildly in both direction. The Cambrian explosion of shareware was the the former. We course-corrected into cathedrals of good software (I still love Windows 2000’s stability, the pinnacle of NT line), followed by the “reasonable timeframe” 4GB Electron apps, etc.

It will swing. Every complex system from logistic equation upwards will oscillate .

Honestly, stop the KYC regime everywhere else.

We're making our law enforcement's job marginally easier, by making the criminals' job infinitely easier by creating millions of juicy PII honeypots.

No, you don't need my phone #, real name, captcha.. if you think you do, realign your incentives, and rethink what else can be used for your real need instead.

I fear the same thing, but still am unsure why or how :)

Google/Microsoft and hosting your own email is a byproduct of how difficult (socially, not technically) hosting your own email has become - mostly because SMTP protocol is inherently broken by spam and patched by social construct (trusted nodes, abuse@, 3+ DNS entries and counting, etc). Purely technical solutions, such HashCash etc, got discontinued in exchange for social ones. Central providers made (sometimes in exchange for, sometimes as excuse of, spam protection) self-hosting socially hard.

Now, I wonder if, and how, once Anthropic and OpenAI need to demonstrate profitability, could hamstring local AI. Which has been /so far/ very valuable for me in doing things that hosted providers don't want liability for, and align against (even if totally lawful and fair use!).

Yes, but equally so, some intelligent voters (who might've moved out of CA by now, as moving might be the best way to solve that disconnect) might also believe that we should be living in a Republic (and the government should not impose majority-favoured restrictions to the detriment of minority) rather than unrestricted Democracy. .

Awesome idea!

I wish we have agreed on some fp16/fp8 format by now to add to it..

That explains the over-representation of Oceans in NYC’s supercharging network, and one of the worst side-effects of opening that network to non-Tesla operators.

Overall I think it’s a good thing, but it’s the closest to Eternal September I ever experienced in my life, the sudden change inclusion of cultural strangers in a shared space with its customs etc.

Correct. Well, almost correct. Will see how much uptake this service will take (if any), and we can probably place it really close to the edge - for now it's on an Oregon server only.

That said, this isn't too far from mechanical HDD latencies of the /real/ SCSI drives.

Thanks! It's truly a special concept somewhere between an overload and a pattern match. And unexpectedly performant - most of these are just type coercions, that resolve compile-time.

Pretty much functions with pattern matching all-across, passing around bitstrings, relatively dynamically typed.

Grab a buffer, make sure it's at least as long as BHS, shove into BHS, ok, make sure it's at least as long as what the BHS requires...

Pattern matching is the hidden power of Elixir that's probably the hardest to get fluent with, it's IMHO harder than Rust's equivalent (because of gradual typing!) - but when it works it blows Pythons' match syntax way, way out.

  # Example: Login Request with immediate = 0x03 | 0x40 = 0x43.
  defp parse_lengths(<<
         _reserved::1, _i_bit::1, opcode::6,
         _flags::8,
         _specific1::16,
         ahs_length::8,
         data_length::24,
         _rest::binary
       >>) do
    {:ok, opcode, ahs_length * 4, data_length}
  end

  defp parse_lengths(_), do: {:error, :invalid_bhs}

The Pi4 shim actually exposes USB device as well. This works way, way better (and IMHO mostly because wired network is better than wireless for latency, ESP32’s feeble CPU aside)

Well, sort of. I think a big portion about it for me was figuring out the TaskAttribute and ACA handling. Basically, many of these assumptions are (well?!) communicated to the block layer by the SCSI protocol (not even iSCSI, that is a thin layer) - but configuring it on the target side was always poorly understood.

We run "Ordered" - without queueing - so we essentially are trading off some /more/ performance for reliability in this situation. The block layer tends to handle it well in most OS.. I'll be game to test what softraid crypto would do to it (luks actually handles it reasonably!)

In terms of encrypted transport - the value is mostly in HMAC layer. That might die oddly if the ISPs decide to mess around with these packets because they look too cute - but for encrypted FS, it shouldn't be accidental, only malicious. (Accidentally, I've seen ISPs get upset over MPEG streams over netcat!)

That's a tricky one. Sort of - we just didn't have enough reason to implement it (nor IPv6 but this is a low lift, and we can get it done quickly).

We do suport VPD 0x83 and advertise consistent NAA/WWID, so linux will support multiple iscsiadm sessions to the same device, and it will be stitched across sessions as paths to the same disk.

We currently hardcode MC/S to 1 as part of login negotiations, advertise single portal and dropping a path will require a re-login.

So - theoretically yes, you can support multipath and it won't fall on its face, but without any practical benefits of it (no bandwidth aggregation and no failover - no ALUA) - at this point it's a single boring target.

But the underlying plumbing can support it - if you have a real usecase for it.

That was another reason for the RPi4 iSCSI shim (https://scsipub.com/initiators/PI4-iSCSI-shim/) - not over scsipub.com itself if you need performance (latency over WAN) - works "OK" but not great.

You can demo it out on scsipub without having to provision local SAN, and I came up with scsipub idea as a consequence of lack of any public iSCSI hosts to try things out.

Yes, it's ridiculous, but I have plugged my M1 Macbook Air to (LAN based) iSCSI through a Pi4. Works remarkably well.

I've answered some down the tree a bit for the inspirational use case for it.

Since I built it, I've started seeing it as a hammer for many nail-like problems - I think that would die down over time;

but.. I have my ESP32 "pendrive" that's net-synced. I have used it to install OS through UEFI-built-in initiator. I have added iSCSI targets to my windows laptop machine (and VMs) - while you need to deal with disconnects and reconnects, it actually works well enough.

It is a terrible idea, that doesn't sound as terrible for odd use-cases. But yes, the ESP32 over 2.4GHz over 3G internet is slow as molasses (20-30kB/s) - but when the alternative is 0.. or walking over there with a laptop, it works OK.
