> It seems the Firewire ports on these things start to go bad after about a decade. If that happens you’re looking at a 3,000 Euro repair bill if you can find someone with the parts capable of replacing them. Hasselblad will still repair them but it’s a pain to get the scanner to them and they charge almost twice as much as third part service shops.

...

> This thing is remarkable. The bigger brother (the X5) even more so. Imacon/Hasselblad had a load of patents on the technology that means no other manufacturer can replicate it. There are other high spec scanning solutions, of course, but none that come close to this form factor.

...

> 15 years passed, at which point Hasselblad discontinued the scanners. The cost of modernising the interfaces was not worth it. In fact, only 7 years passed before Hasselblad effectively discontinued them as that was when they stopped updating the software.

This is the dark side of patents.

A company that has used the patent system to run everyone else out of business despite not being particularly innovative (the author describes a "simple" system for assuring the film is perfectly flat), refuses to keep their product line up-to-date or properly support it, charges a fortune for a service that from the sounds of it doesn't actually fix the problem with the interfaces, which may have been purposefully designed to fail anyway...and an entire market segment just dies.

It's sad that those $3000 bills for repair will probably be going to organizations like museums trying to preserve their collections or make them more accessible. Or be unaffordable to such organizations.
But it does lower the bar for asking questions a lot. Before you ask a human you have to do a sanity check. Most obvious is asking the same as last week but it could also be something readily available elsewhere.

That sort of irrational behavior makes me wonder if das muskrat has his paws in this. If he was willing to drop $44 billion on Twitter, this is pocket change by comparison. And he's been desperately trying to get that guy to stop tracking his jet.

The data is still freely available and will be distributed via another channel.

The ADS-B transmissions are still freely available but the value is in the aggregate product. In the case of ADS-B Exchange that aggregate takes a ton of work from volunteers who (if the comments here are any indication) are inclined to stop volunteering. An ADS-B receiver has a range of dozens, maybe hundreds of miles. Without that network of volunteers Joe Schmo in Santa Cruz will have no way of tuning in to that freely observable transponder in Austin.

Playing Devil’s Advocate here, but minimum wage earners are being subsidized by local, state, and federal governments. They usually don’t have to pay full price for groceries, rent, healthcare, or education. The bottom of the middle class are the ones suffering the most right now as they make just enough to not qualify for these subsidies, but not enough to comfortably absorb recent increases to their cost of living.

I think along the same lines, well, not the living in a terminal bit, but have worked with people who would probably be described as neurodiverse that absolutely hated files moving from the order they'd left them in.

Xcode projects still keep files in the order you leave them in, unless you tell it to sort them. I'd guess 99% of people, like me, sort a group every time they add a file though.
It is still micro optimization to ensure that those instructions are used when the compiler is too dumb to use them. You can say that they are niche, but that is different from it being micro optimization.
LiFePo can last longer than Lead-Acid. It depends on the usage.

LiFePo has a very high maximum cycle count. But after ten years, they'll die anyway. The only way that you can actually achieve a cycle count as high as the specification says is if you're cycling the battery two or three times a day, which I can believe if you're doing grid-levelling, but not if you're providing backup for your solar panels.

For lead-acid batteries, be aware of the difference between normal lead-acid, which are optimised for standby operation, and deep-cycle lead-acid, which are optimised for long life under regular cycling. Normal lead-acid batteries will die very quickly if cycled - they're designed to be charged all the time, and drawn on for very short period, like a car battery or a UPS.

Deep-cycle lead-acid batteries age by cycling, in contrast to LiFePo, which age by elapsed time. Their maximum cycle count is much lower than LiFePo, but if you're cycling them every couple of days, like in an off-grid solar project, and you're avoiding draining them below around 40%, then they can last 10 years.

So, if you want to cycle your batteries two or three times a day, then LiFePo is going to last a lot longer than Lead-Acid. But if you're cycling every couple of days and limiting the drain, then they can last about the same amount of time. It depends on the usage.

What helps with Lead-Acid is because it is that much cheaper than LiFePo, you can buy a larger capacity Lead-Acid battery for the same or less money, and then for the same performance requirements that larger battery will be drained less and at a lower rate, and therefore be less stressed and even last longer.

I think we don't use Lead-Acid as much as we do for several reasons:

1. Lead-Acid batteries have a reputation of flaking on us after a depressingly short amount of time. But that reputation has been earned from normal Lead-Acid batteries, not deep cycle ones.

2. People get scared by the lead in them, and how lead is toxic and we should be stopping using lead in everything. But really, lead in these batteries is not a danger to us, and Lead-Acid batteries are one of the best recycling success stories in the world. That lead isn't generally getting out into the environment. LiFePo batteries are much harder to recycle.

3. Electricians recommend installing expensive stuff, because then they get a bigger commission.

4. Lead-Acid batteries are commodities, but LiFePo batteries are new and exciting, and have aggressive marketing.

5. Lead-Acid are bigger and heavier for the same capacity than LiFePo. So, a LiFePo installation is going to look prettier in a nice consumer unit and be easier to install. They're heavy enough as it is.

> It makes me wonder why Aliexpress doesn't have more warehouses in the US

My guess would be liability. A lot of what's sold on Aliexpress is... questionable. Fakes, products that are patently unsafe or don't meet US regulations, fraudulent specs, etc.

What's happening right now is basically a bit of a laundering operation where small "front" businesses in the US, often registered to residential addresses, import small chunks of the inventory, collect markup, and resell it domestically on Amazon, eBay, Etsy, walmart.com marketplace, or whatnot.

And if their USB chargers keep catching fire or a big brand gets uppity about trademark infringement, the retailer disappears, and a new one pops up. Amazon gets some flak in the media every now and then, but they are several steps removed from the phenomenon.

If you had a Chinese megacorp with a large US footprint, they would likely soon find themselves in hot water with all kinds of regulatory agencies. Partly because there would be a single party with gobs of money to go after, and partly because of anti-China sentiments.
My thought is that it is a derivative work from the training data. The creativity comes from what you choose to or not to include.

You have a good point on my individual control of a public company is quite small. Luckily, basically every single other stockholder has the same reason for owning the stock as me- making money.

There is basically no risk that a different group of stockholders with more voting power want to run it as a public works jobs program
Nearer the end they add that they were "not prepared to drop 5,000 Euros on it"
I think the tip jars are a scam, but tipping waitstaff is important. However: Tip waitstaff with cash because their wage is much lower than most tip-jar situations.

Restaurants pay workers the minimum wage for tipped workers ($2.13/hour in most states), but must make up the difference if the worker's wage plus tips don't equal the minimum wage ($7.25 in most states).

When I waited tables, we were forced to turn out our pockets at the end of a shift and count out our tips in front of the boss. A lot of us took cash tips and stuffed them in our shoes beforehand.

Plus waitstaff had to pay for the credit card charge (2% at that time for MasterCard and Visa) if someone charged their meal, so reducing that as much as possible was helpful.
Power availability?
Picking nits like this not only fails to advance the discussion, but in my opinion makes it worse.

You can do the same thing with literally any rule. Why does one have to be 18 to buy cigarettes, an addictive product that will kill you if you use it long enough? Does something magically happen at age 17.9999 plus epsilon? Of course not.

Regulations often draw arbitrary lines because that's a relatively easy way to improve a situation without getting bogged down in some sort of much more complicated test. E.g., we could mandate each person who wanted to buy cigarettes undergo a deep psychological evaluation looking at their personal history and testing their ability to make truly adult decisions. But that would immediately be seen as unduly burdensome (and nitpicked exactly as you're doing now).

And in any case, you have missed or are ignoring that one can now pass a test to become an accredited investor, no capital requirements at all. So in addition to being tiresome, your point is also out of date.

I think there are adapters for digicams.
It depends on your model of NaN. If you think there is only one NaN value, then the two values return the same result. If there are multiple distinct NaN values (i.e., you distinguish between NaNs with different payloads), then the resulting payload of an arithmetic operation is... not well-specified.

Most hardware architectures (x86, ARM fall into this category) pick the rule that the payload is the Nth operand (usually first, sometimes second) when multiple inputs are NaN. I believe there's some hardware where the lesser of the payloads (converted to an integer) is picked instead. RISC-V dispenses with NaN payload propagation entirely. There is theoretically the ability for hardware to generate a new unique NaN with the hardware address of the instruction into the payload, but I don't believe any hardware actually does it.

Most programming languages do not generally model NaN with greater fidelity than "there is a NaN value" or maybe "there is a distinction between qNaN and sNaN."
That's not actually true I'm afraid. I mean specifically in this case, how would cheaper and more advertising, and fewer free products like Gmail actually help anyone?

I think people have gotten the idea that competition is good for its own sake. But it's not, it's just a means to an end of getting more quality, lower prices etc... If an industry is obviously making excessive profit, that's a good case for competition being in the public interest. With complex industries like advertising (when the "product" is actually of no interest to the main "consumer") it's much more complex than just "lower prices means success"...

Sounds like maintaining these high end medium format cameras and scanners can be a real hassel.

I have a Nikon Coolscan V and nothing is wrong with it but the switch, but it’s hardly worth repairing or trying to sell on eBay. Working, it might be worth more than I paid for in c2005.

Because the data can often easily be tied to specific people.

You also can't set up a camera on the side of the road and store peoples registration plates and times when they drove past.

You could also easily track cellphone IMEIs and locations in the same way these services track aircraft, that's not gonna fly either.

Obviously you'll be completely fine if you only store data on commercial aviation, general aviation will pretty much immediately veer into GDPR territory.
> I really don't see Wirth in reality as a huge influence in the history of programming language design.

C# is influenced by Pascal and Modula-2 because Anders Hejlsberg had a huge hand in creating it.

Go and Lua are also quite heavily influenced by the Wirthian languages.

Ada is also a direct descendant of Pascal and Modula-2. For a while in the 80's, Ada was more popular than C++ because of the DoD standardizing on it but the DoD and NASA still use it today. NASA's Artemis project uses Ada. The Canadian air traffic controls system all run Ada.

Wirthian languages have been focused on safety for 50 years. The industry is just now catching up with safety-focused Rust as a first step. It's long overdue. C and C++ were dangerous enough offline but using them online is just asking to get hacked. Sure, safe code can be written in them but not many C and C++ programmers are capable of doing so. Why wouldn't you want a language that handled the bulk of that for you?

Yes, sub-saharan diversity is even more diverse. But diversity among African Americans is still much higher than that of the white population. In fact, most African Americans descended from enslaved have 20-40% European/white DNA (and for unspeakable reasons, most of that DNA is of the supposedly wealthy, elite, most intelligent white progenitors of this country). So I just see no way to make any useful extrapolations based on genetics. Especially considering the externalities involved in being Black in America.
I'm due to interview someone tomorrow who has had 20 jobs in 25 years... a few 6-month contract positions but mostly 12-18 months in 'permanent' roles. I'd estimate that most of the roles would have been on project-based work of >2yrs duration.

I'm keeping an open mind - this person isn't ruled out but it's difficult not to read something into the possibility that they've never seen through a project.

They absolutely would notice, you are only allowed to under pay tipped staff under the assumption that with tips they rise above min wage. No tips and all of sudden you have to make the difference from 2.50 ish an hour to min wage which can be 16+ here.

Can you do it in 1000 logic gates, in a size of 150 x 170 um?

There are very few things that are more complex than toys which fit in that space. It's primarily a learning opportunity, not a hack to build a product.

Also, most of the hard work in Wi-Fi and GPS modules is not in receiving the binary radio signal but in the protocols to decode it. For wifi, the 802.11 protocol would require your PHY to provide at the very least the orthogonal frequency-division multiplexing, but you're probably expecting something closer to a Wiznet chip that provides the fundamental stack available from eg. the lwIP project.
I wouldn't call ASML's products complimentary. They are the only machines capable of EUV lithography. Without EUV, nodes smaller than 7nm wouldn't be possible. But even before EUV they were the leading manufacturer of lithography machines. They deliver to all the big players like TSMC, Samsung and Intel.

They are so important/valuable that the US government is negotiating with the Dutch government to ban ASML from selling EUV machines to China.

Ah, I just saw it, thanks.
I love this feature. I use it most of the time in large functions where I can group some lines as one logical piece but not generic enough to be a function. It helps with reading the code back and prevents leaking vars into rest of the function scope. Such blocks end up becoming scattered single use functions when extracted out which isn't ideal.

K4 is the implementation language of q, kdb is the database part of the language. Most q is just named utility functions written in K4. There isn't really much difference in what the machine does with them under the covers, but when stuck on a problem talking about q is more likely to get help than k.

You can provide up to 8 named inputs in a function definition.

q example for running sum of 8 inputs:

q)f:{[a;b;c;d;e;f;g;h]sums a,b,c,d,e,f,g,h}

same in K4:

q)\
f:{[a;b;c;d;e;f;g;h]+\a,b,c,d,e,f,g,h}

They might have a patent on this particular setup, but the FlexTight system produces worse results compared to traditional drum scanning. Due to the way it uses a lens between the CCD sensor and the drum also means that you get some quality issues around the edges of larger frames. It also means you can't scan large formats like 8x10. It's cool tech and it is a shame that it's stuck behind patents, but it's not like there's not other options out there.

Also the hardware is funny. IIRC they didn't iterate on the actual components much, and the move to FireWire basically just integrated a SCSI->FireWire adapter into the case. I haven't seen the inside of an X1/X5, but I'd be interested if these could be repaired by using a different SCSI adapter of some type.

Sadly it seems SANE has no Hasselblad drivers at all, which probably makes sense given that these are professional devices with a very small install base. Even worse, given the high end features I suspect the firmware isn't just a clone of some other device like it is so often with scanners.

Probably not too hard to reverse engineer with some skills and tools, but well beyond what a random photographer is likely to be able to do. The real shame is the company squatting on the driver source code and refusing to update it. It is supremely frustrating when companies treat the driver software--useless without the hardware for it to run--as top company secrets. The software does nothing without the hardware your company sells, so who cares if someone could "steal" it?
Pascal was designed for learning programming concepts, not for real world use. Others modified it for real world use but Modula-2 was designed for real world use and is a huge improvement over Pascal.
