What a nice collection. The 48G was (is, as emulation on my phone [1]) my all time favorite. The LCD of my real one tarnished more and more until it was unreadable. A list with links to emulators can be found here [2]

> you can run Linux on IBM hardware, but then.. why?

Don't know if this counts, but you get much memory with fewer cores. For software where licensing is coupled to cores this quickly gets cheaper.

And for what I see in production the hardware is more reliable in comparison to two large x86 vendors. This is of course based on a small number of systems (n~100)

This is a old quote and IIRC was e.g. for the way AIX handles services (SRC / System Resource Controller) and stores configuration data (ODM / Object Data Manager). It felt 'alien' for admins used to use rc scripts (which are possible too) and files in /etc (used in aix too).

Now, nearly three decades later, we have even more automated and integrated mechanism 'systemd' and I think that there would be still features worth adopting from AIX. Not the first time i have such thoughts with an OS slowly vanishing.

Image Alchemy [1] Unfortunately not longer available. But one of the greatest image conversion software I know (including most of the here described algorithm for dithering and some more). And this feature set is from at least 25-30 years ago.

I'm always getting a bit nostalgia when I see these dithered images and remember the time then with the fascination for the opposite direction: 'true color... wow that would be great' ;)

This is most likely the reason for this post

I've found a video [1] on youtube, describing the failures listed in the article in plasticstoday. When i watch the videos seem several of them to fail at the bond between elements of the construction.

As soon as you use something like SAP or Oracle the number of offically _supported_ distributions quickly decreases. As example SAP HANA: RHEL and SLES or for example Oracle Database: RHEL, OEL (based on RHEL AFAIK) and again SLES.

So it is not only a question if it would theoretically/technically fail on another platform.

Cant say for devices with higher resolution and stronger magnification (e.g. for hunting) but i don't think so too. Definitely not for the resolution and magnification we are talking here.

Agree. With common I was thinking of "not specialized rugged phones" but more consumer class. (As you have written Samsung S5, S5 mini, ...)

Nice idea, but I think for THIS application the FOV is to large and the resolution (160*120?) is to low. Of course the extraterrestrial knew that and therefore allowed the integration of the lapton chip into the phone <8-)

I use a dedicated thermal camera with bit higher resolution but higher FPS. As others have written they are quite useful as you see thing (even not ET) you could have measured with an IR thermometer if you knew they were there.

Water resistant (e.g. 30 min / 1 m) mobile phones with exchangeable batteries were quite common. They had easy to procure LiIon batteries which could replaced even by a clumsy person in minutes.

Would prefer that to a watertight phone with non replaceable batteries as aging or dying batteries are more common in my experience than my desire to go on a dive with my phone.

You know, that they used a different calendar back then, right?

Voting running after midnight local time (where leap seconds get inserted) and dependent on sub-seconds, with only five leap seconds since 2000 introduced reads like a really interesting case.

I don't get it what the 37.3 kWh are supposed to mean in this context. This is for sure not the energy required to keep a person 'alive', but all energy (manufacturing, transportation, ...) assigned to per person.

The energy consumption for a physical working person is approx 4000 cal per day (4.6 kWh). According to [1] it takes about 150 BTU (0.043 kWh) per hour / ft^2 to melt snow. To clear/melt an area of 5*15 meter this requires about 35 kWh.

(I have rough calculation of the energy required to melt 20 cm of -5°C cold snow and get a four times higher energy requirement, probably i have missed something.)

Cant answer the question and my knowledge is only from 'one interested' but from how long (~20 years) it took to build the current EUV source and how complicated the alternatives look this is for sure no easy feat.

Can recommend [1] as the title say about the light source. Very interesting even for a non professional (and [2] as on high level overview of the machine and [3] as longer documentation inside ASML).

That sounds like a very energy consuming method to solve the problem.

See e.g.

Probably quite costly for the device, but would a Iridium phone number work? Such [1] a device should (not tested ;) have connectivity, even in Antarctica. I don't know of course if the same filtering for MFA-SMS applies if the number has a +8816 or +8817 prefix.

Doesn't look too good from my laymans point of view [1]:

"Title: Maintenance on eight French nuclear reactors delayed by strike ... French nuclear availability is currently at 51% of total capacity with 26 reactors offline for maintenance."

[1] https://www.reuters.com/business/energy/edf-says-strike-hits...

Yes, but it's not Germany alone. A lot of the electricity produced in Germany is exported to other countries. And if this is not longer possible this would be a problem for them too. More aggravating is the circumstance that France, another European country that usually exports electricity cannot too as many (half) of their fleet of nuclear reactors are in maintenance.

You doesn't need a "ML Invisibility Cloak", it seems as a shopping cart [1] was at least some time ago (2018?) sufficient.

Tell that e.g. Tesla

What I've read they burned a lot of money and hat large problems scaling nevertheless. Which I don't find too surprising, not because they are unable, but because it isn't easy to scale.

From my experience and from what I read scaling people roughly a power of ten is a larger change in an organisation and therefor likely a challenge. For _any_ technical process the boundaries might not be strictly a power of ten but i would say that scaling a power of a hundred is a challenge if this value is not already reached on any process in your organisation.

That won't help your customer expecting their 'baby' after three month due to the increased mother-workforce ;)

I think we have left this level a long time ago where one could answer: The system is in a physically secured location. As long as there is no physical access it should be safe.

See mobiles like iPhones, gaming devices like XBox, Playstation etc. authenticators like chipcards or security token and HSM. All have to asume that the attacker has physical access to the device.

Security Engineering Ch. 16 "Physical Tamper Resistance" is a good read for some special classes of devices. But I would recommend all topics from this book even unrelated to this thread. ;)

I would think that it can hold 1TB of RAM _per_socket_ (with 64GB DIMM), so _2TB_ total.

I can say that I'll woke up for years from the deepest sleep in 'seconds' when hearing this melody.

We did the same several years ago. At the time I found http://www.cs.toronto.edu/~bianca/papers/temperature_cam.pdf quite interesting. I didn't find many other precise papers about issues when running at a higher temperatures, but many "should" and "can".

Based on ASHARE there are two guidelines from HPE and IBM: https://www.chiltrix.com/documents/HP-ASHRAE.pdf https://www.ibm.com/downloads/cas/1Q94RPGE

We found (by measurement) that some places in the datacenter with suboptimal airflow are well over the average or simulated temperature so one can leave the safe temperature envelope if one isn't careful.

A bit nitpicking but even with a proper implemented HA solution there would be a service interruption.
