<p>In Finland and most of Europe have 230V one phase, 400v in three phase. And bare single phase subscription haven't even been available new houses for at least 45 years any more.<p>But if you buy an old summer cottage further away from permanent living areas it may well be that a) you don't even have grid there or b) if you have it's single phase and three phase upgrade would be too expensive because you are being billed building cost for that work all in front.<p>Using that single phase for sauna stove needs then so much that it's not allowed by code or if you would be able to convince some electrician do some kind fo switching other devices off when stove is on most perhaps do not like to pursue that and choose wood stove their sauna instead. That's known working solution and remote location it's also a secondary heat source incase grid were down due some storm fallen trees on wires which mess cleaning takes several days etc.</p>

<p>I think I've heard US it's mostly no water at all on stove and Germany I've heard they have had these sauna-masters who come and cast water on stove.<p>Neither of these are practised anywhere in Finland at least. But there are at least one Finnish swimming bath where they had to limit steam competitions and made a button controlled mechanism to administer water instead of free usage. Not because electrical shock prevention but because bad human behaviour per se.</p>

<p>That "electric heater stones on top" is usually called stove, "kiuas" in Finnish :)<p>When needing to define type of stove, it's electric stove, wood heated stove. Latter has two types, which continuous wood burning is still common (this stove you can add burning wood during bathing) and older not so much any more used before bathing heated type stove which you cannot add wood while bathing. Oldest type is smoke-sauna, which doesn't have chimney at all. Wood is burnt in stove when heating, then when burnt enough sauna is ventilated first and then bathing starts.<p>But all these different heating elements are commonly stoves, just adding electric-, wood-, or smoke- stove is added context requiring.<p>Infra saunas then have those lamps of course, no stove there.</p>

<p>Yes, that it was especially rural environments and not having much options otherwise to live around while building.<p>Sauna that was built then wasn't just one hot room, but it also had at minimum small changing room dressing/undressing, relaxing between turns in steam room. Also if it was first building made then adding also lounge which served as living space with beds and cooking stove while building house was common. With sauna you had place to stay warm first winter, able to get warm water, wash clothes, yourselves and even a give birth old times. Building sauna first made lot of sense.<p>These days sauna for home builders is more about getting sauna somewhere in that floorplan where works well for the intended users of that house.</p>

<p>Besides water proofing wooden boats and long time ago ships pine and fir tar it's been used protecting wooden roof tiles when they were a thing and still are used old wooden churches keeping and restoring.<p>It's used small amounts in additive in soap or shampoo mostly as a scent, mouth pastille and lozenge a for taste, animal health care kind antibacterial and bug resistant etc. long time ago.<p>Quite lot of applications especially old times long time ago before more scientifically developed medicines were commonly available. These days less there but it's used as a scent or for flavour.</p>

<p>That is growing trend in Finland too. GenX and younger seemingly use less sauna compared to older generations.<p>Thus when it was common to build sauna for a while all new all least family size apparments late -80's and -90's that has been less common later decades. And it's become so common people not using saunas already built bathing and instead use it additional storage. Which has unfortunately caused even some fire accidents if stove circuit breaker was not disconnected. Last year we had this kind of happening when child apparently had played with the sauna timer switch and activated it.</p>

<p>Correct, most saunas at homes were they apartments or family homes, businesses, public saunas etc. were built using electric stoves when they became commonplace during -70's.<p>But traditional summer cottages and villas have been either intentionally or still built wood burning stoves unless three phase power is easily available not bring cost up too much because remote location and long distance to grid. We have about half a million summer cottages in Finland. Which almost all have saunas and I would guess that perhaps 5% would have electric saunas as most summer cottages are built quite long time ago and off grid.<p>There are fancy (luxury) summer cottages where there is not one but either two or even three saunas built or moved there. All different types of course if having many. One electric inside for convenience.<p>Traditional (continuous) wood burning sauna, "jatkuvalämmitteinen" in Finnish, right next to lake because that type is consider to give better 'löyly' (steam in sauna) than you get from electric stove and thus preferred by many.<p>Third if some have is usually oldest type, the smoke-sauna. Which is really nice to have if you can afford keeping and have patience to make use of it few times a year. It takes lot of time and bit of knowledge too to warm it up which can take up to 6-8 hours, before it's ready to start bathing there. This was most common type about hundred years ago in country side.<p>Fourth type is or mostly was between smoke-sauna and continuously burning stove sauna. Its stove burns wood during heating, but then during bathing it's just releasing heat accumulated during heating. This type name in Finnish is "kertalämmitteinen kiuas" ie. onceheated-stove. And was most common in towns and cities before continuously warming stove was invented and became popular about 60 years ago.<p>I go sauna four times a week, once evening where I live and three times a week early in morning when I go swimming to (county owned) swimming baths.<p>e: typos, and clearer expressions.</p>

<p>I'm not one that he flies with gamma spectrometer. But I've had RadiaCode 103G since Dec 2024. It's pretty neat device that can be brought with you almost anywhere.<p><a href="https://radiacode.com/" rel="nofollow">https://radiacode.com/</a><p>It's made in Cyprus (EU) and has apparently received some EU funding. Using Google Search AI mode and asking what is CEO Sergey Shek connection with Moscow Radiological institute gave me following reply.<p>"The connection between Sergey Shek, the founder of Radiacode (formerly Radiascan), and Moscow's radiological research centers is primarily rooted in his and his team's professional and academic history.
The key points of connection are:<p><pre><code>    Academic and Professional Origins: Radiacode’s founding team consists of Russian physicists and engineers who were educated and began their careers at prestigious scientific institutions in Moscow. These include researchers formerly associated with the N.N. Semenov Federal Research Center for Chemical Physics and other centers specializing in nuclear physics and spectroscopy.
    Early Product Development: The company's initial products, such as the Radiascan-701, were developed in Russia using the technical expertise gained at these Moscow-based institutes. The technology behind their current high-precision scintillation detectors stems from this scientific background.
    Relocation and Independence: Following the start of the conflict in Ukraine, the company officially rebranded as Radiacode and shifted its headquarters and operations to Cyprus and the United Kingdom. Sergey Shek and the company have sought to distance themselves from Russian state institutions to operate as a global, independent entity.
</code></pre>
Today, while the "scientific DNA" of the company originated in Moscow's radiological research environment, Radiacode operates entirely outside of Russia and focuses on the international market for hobbyists and professionals."<p>Russian background didn't sound good to me for obvious reasons. Thus I did not install app to my daily driver phone and use a separate Android device for this app. But the device is nice and app quite good for what I've used it.<p>Adding: You can find videos about the device from Youtube.com</p>

<p>NiMH batteries are surprisingly robust.<p>I've long had Palm Pilot Vx which I bought 2001 and used daily till 2011 when I switched my phone to iPhone 4s. Then I did factory reset and put it back in box it was sold and shelved it. End of January this year I was thinking I need to start clearing up what I've saved and see if would recycle, sell or send something to a museum.<p>I put Vx charging on its docking thing and left it there overnight (first checking it was not getting any warm) and next day I picked it up to see if it still works. It does, battery status did show full. I fiddled it perhaps almost half an hour and battery status was still full. So I left it on desk and thought to check it daily how long does battery charge last if idle. I think it was fourth of fifth day when change was only perhaps 10% percent. I have no real recollection of how much standby idle days was left after that 10 years in use, it's too long back and I didn't take any notes of it then. Just wrote in note date when I put it back in box.<p>I'm genuinely surprised that 25 years old darn thing still works, when it had been 10 years in use and then 15 years shelved batteries completely drained.<p>Now that's something we've lost when moved Lithium batteries, which don't survive being years completely empty. NiMH's just don't care, they seem to sustain capability to charge and keep charge after long periods of time unused.<p>I've had few NiMH triple-A batteries in use 12 years and I thought that was a stretch, but no. That Vx blew my mind how robust device and it's battery are.</p>

<p>Yes, the autonomy level of these robots was what I was yesterday emailing with my former colleagues we were wondering. Two months ago CNET & PC-Mag posted following video which suggests more about robots movements being assisted by humans. And it also shows Chinese have being edge of the development at that point.<p><a href="https://www.youtube.com/watch?v=jXTibM33SDg" rel="nofollow">https://www.youtube.com/watch?v=jXTibM33SDg</a><p>However, then another short video bit alike popped up and is puzzling too.<p>Apparently Unitree robot is playing pingpong match like a pro. Sorry about german announcer, I couldn't find with english.<p><a href="https://www.youtube.com/shorts/BgD1ukTyNnw" rel="nofollow">https://www.youtube.com/shorts/BgD1ukTyNnw</a><p>There is another match viewable by pressing that "Robot plays ping ppng #robot" arrow.<p>How about that robot? Is it human assisted or not? Our opinions diverted, I'm quite sure it is assisted but my former colleague thinks it's got to be autonomous as it would be too difficult and slow to do that fast movements with remote control assisted robot.<p>It would be nice to hear opinions about that playing robot too if anyone could provide some insight in that.<p>edit: I think the serve waiting robot hand movement and after losing wiping left eye gesture as a disappointing a bit in my opinion gives up it's human. Or if not, why would a robot do such a human like gestures.<p>edit2: OK, good points, I see now. It's definitely a fake. Thanks to all who replied :)</p>

<p>Well it depends, on still using.<p>I've been mostly using emacs past 30 years ie. about the time when system memory wasn't any more constraint which while single user was about 8MB at least. But I did earn my living before that about 7 years mostly using vi as most usable editor in the system and that 8MB was luxury most of that time.<p>But even emacs IMHO was and is vastly superior, vi still had it niche fast small edits and especially before log based transactional filesystems. After power outage or bad brownout event system crash there was great chance you got to fixing filesystem with fsck (which did often take lot of time) and worst cases finally debugfs trying to fiddle bits that you get fsck fixing rest.<p>Bringing system up with old system could be tedious. Before you get system enough up single user mode and just root fs mounted you had to resort you way forward using those modest tools you had there. It was really great if vi did work, but it too required sometimes more memory than you had before swap was active. If not, then ed was your friend, ex is just vi without visual mode.<p>For a long time vi was also able to edit very large files. It did not require reading whole file in memory before it allowed editing as for example emacs did (or mmap's it memory later).<p>These days I use vi for quick edits like someone above mentioned and like it more than any later replacement (nano etc) if emacs is not there, not worth installing it for just quick change or when can't install on (embedded) or someone else's system for any reason.<p>Vi is often available also *bsd based appliances which I've been using like Junos, Netscalers, etc.</p>

<p>Oh, my bad. How didn't I notice my mistake right away. That 25 is grossly wrong, I should have checked before using that. The correct line to get subnets is<p><pre><code>  $ sipcalc -s 24 10.0.0.0/8 | grep -c Network
  65536
</code></pre>
Which increases significantly global routing table size of course. I apologise my mistake on that matter that I should have noticed before posting.<p>Anything else I wrote about changing prefix advertisement is correct. You should and need to communicate your advertisement changes in good time to your peers and let them time to make changes.</p>

<p>>or even by normal load from someone deciding to split a /8 prefix into /24's<p>If that kind of happening directly from load of added 25 routes it's quite hard to believe it.<p><pre><code>  # 10/8 prefix here only to show how to get number of new routes added.

  $ sipcalc -n 24 10.0.0.0/8 | grep -c Network   
  25
  $
</code></pre>
BGP peering routing policies have then been for the good reason constructed in way that they expect advertisements "exact accept" with a prefix-list with that /8 prefix, because that's is expected when peering is agreed even when not explicitly stated by many. This expected best practice following goal to manage and prevent internet routing table being filled with superfluous routes.<p>But anyway, sudden change from /8 to 25 x /24 without first noticing your peers and giving them time to change that "exact accept;" to "orlonger accept;" is quite sure footgun if you don't know common principles of network management. But usually that kind of screwup blast radius is local mostly local only to that /8 prefix.<p>Not sure though how that could be technically avoided in BGP protocol or router control-plane (router OS config) design. Policy filters and best practices how to use them have been set for good reason. Not just to irritate and make things harder than they need to be. We certainly did not do that while I was still working.<p>Right, something else what could happen with that kind of sudden change is. If that peered had also other peers which had instead "orlonger" in place traffic would then switch to that, what could have some side effects like saturated links, slowness or even increased costs. Too bad, and may happen. But principle is that communicate your routing changes in good time before you actually make the changes. That will prevent most of this kind of problems ever happening to you.</p>

<p>>Using "easy listening" as a pejorative has always baffled me. Why does music need to be difficult?<p>Yes, I agree with you, it shouldn't and doesn't need to be.<p>But some things like music be it Jazz or something else isn't always just matter of listening but way of self establishment, way of life living or pursuing life, way how they seeing themselves and communicate themselves to others. I'm not in to this or studying this or anything else, but it's known behaviour model and you find studies if you like to read about it more.<p>Right, some Jazz aficionados tend to be like hipsters. Who despise and keep unorthodox anything but their likes would grok. A way of self establishment and having reason to keep themselves different. At least a bit better than others. I'm not claiming everybody are, but I certainly have met few of those quick to classify someone things they like.<p>I find my self like more West Coast Jazz bands and artists performances older I get. And if I'm not completely wrong it might be a more common trend their share has increased over the past ten or so years playing in radio stations too at least where I live.</p>

<p>Yeah, that's true that water thrown to a stove isn't much contained anything but that bathing room. Some of water will of course flow between stones bit deeper, but there is plenty of room to expand when it boils to steam.<p>Some firm hissing, minor clanking noise from stones is normal and even bit sharper noise when a stone cracks is what water use on stove causes when stones get old and are used lot. Stove should be cleaned periodically when it's cold depending on how much it's been used and there is need to replace stones or even all of them if it's been long time and there is some sand accumulation  stove bottom grill or plate, whatever it has to hold stones falling trough. Family houses cleaning perhaps 1/yr and public saunas open 6 am to 8 pm 300 plus days a year, they will do stove maintenance every or every other month.<p>And yes, getting good amount of steam of course is what's been whole goal in this kind of sauna use and what we prefer. Some other places where they have begun to call it sauna too, they may not even allow to use water nothing but as drinking water and usually they don't warm up that 'sauna' as hot as we tend to do or if they do it's more like Turkish bath type then.</p>

<p>Well, that's about what happens in Sauna with electric stove.<p>In Finland we do it every day and have done decades already.<p>Those who may not know electric stoves have been about fifty years common use at least in urban environments. Stoves have anything from three, one in each of three phase current used heating elements (resistor coils) 400V 6-8 kW power draw commonly in small house stoves and 2-3 times that swimming baths saunas stoves.<p>While sitting topmost sauna benches bathing, we throw fresh water from bucket with a sauna laddle (saunakauha) water to stove(s) anything from small drippings to a pint with trying to little spread it out. This is to get steam and make it pleasant relaxing 'löyly' as we call it.<p>The stove is usually heated about an hour or so before starting bathing to get temperature somewhere 70°-100°C (158-212°F).<p>It's not advisable to have stove showing those red hot glowing elements peeking out behind stones, but it does happen if stones were not laid properly. But even if water gets directly to elements those will not break or get any damage as they are made intentionally to resist that.<p>So boiling water practically immediately does happen, it's not particularly dangerous when applied in circumstances where equipment is made to withstand that is nothing miraculous. And that really happens millions of times each day in Finland and some other places where that kind of sauna culture is practised both at people private homes and also public swimming baths saunas alike.<p>I will be observing it next time about in 14 hours from this writing as I'm going swimming as usual tomorrow morning at 6:00 am. when pool opens early tomorrow, and then likewise twice more (Wed, Fri). Also once more (Thu) evening sauna reservation slot i've got this flat I live.<p>There is a quite good english page about Finish sauna in Wikipedia, but to get a glimpse what modern sauna and stoves look Harvia a long time stove manufacturer web pages you get some sense what I'm writing about.<p>- <a href="https://www.harvia.com/en/" rel="nofollow">https://www.harvia.com/en/</a></p>

It's their ToS generally prevent it being collected and resold why MaxMind told me that they don't use it.<p>Thus the LOC information I had updated RIPE DB in our records LOC or any other information there were not used by MaxMind. Or at least that's what they claim. True or not I don't know, but that's what they tell if you ask from them.<p>Also apparently they did not use LOC records from the organization domain I maintained DNS LOC records either. And I got no answer why nor what they use as their sources of information. As it's more likely some kind of trade secret of them.</p>

<p>A bit late to reply so much longer (10h) I posted my comment. But just for the record here I go.<p>After reading that RFC8805 here it's what it writes situation at the time of publishing August 2020.<p>"8. Finding Self-Published IP Geolocation Feeds" and subsequent<p>The issue of finding, and later verifying, geolocation feeds is not formally specified in this document. At this time, only ad hoc feed discovery and verification has a modicum of established practice (see below); discussion of other mechanisms has been removed for clarity."<p>and subsequently<p>"8.1. Ad Hoc 'Well-Known' URIs<p>To date, geolocation feeds have been shared informally in the form of HTTPS URIs exchanged in email threads. Three example URIs ([GEO_IETF], [GEO_RIPE_NCC], and [GEO_ICANN]) describe networks that change locations periodically, the operators and operational practices of which are well known within their respective technical communities."<p>I spent also a moment trying to figure out what can I find about its adoption and use and didn't find much of it. Some blog posts, articles and comments to question whether Amazon AWS or Microsoft Azure support it and answers were pretty much nope, no they don't at least yet time of writing last year and this year.<p>Thus I'm concluding it's unlikely any major source of location information for GeoIP providers like MaxMind. Nope they're not, it's too marginal source for them to spend time on so little used spec yet.</p>

<p>That's a good question.<p>During 2024 Summer Olympics my then employer which DNS and core network I was still managing as I returned summer holiday. I was told by helpdesk our users around different locations at campus were not able to open national TV broadcaster streaming services and view the games.<p>I found out by asking few of these users that they got denied claiming to be from UK and that streaming services were not allowed abroad. TV broadcaster told me once I got someone to know anything about the matter reply, that they use MaxMind GeoIP service. So I went to see and test few addresses from MaxMind debug page and that clearly showed many addresses from around 20 subnets of /16 our IPv4 CIDR block were showing the same.<p>So I sent email to MaxMind support asking why and tried to find out means they use to check where each network is located and populate it to their GeoIP DB, which then clients either mirror or use remotely from their service.<p>After few emails with their support that they did not use RIPE (RIR) database at all as RIPE terms of use doesn't allow using RIR information for commercial purposes. So MaxMind neither did not apparently use WHOIS (RDAP) LOC records, and wrong information did not update from our LOC records DNS had either.<p>I never got any explanation how they figure out where that IP or CIDR block is being used. Between the lines I was assuming it's perhaps some kind of trade secret they don't like to talk about. Maybe it's using mobile devices location service or like, but amount these days VPN's are being used that could lead them updating bogus information to database service use they then sell and naive customers trust <eh>.<p>But most I was surprised by that how easy it was update information, basically just communicating clearly and writing polite convincing message they seemed to take that information pretty much by face value and that I was sending my messages from DNS SOA RNAME address.<p>But if GeoIP data provicers don't use that then who or what services do, that I still have no idea.</p>
