  • Osaatko yhtään sanoa että kuinka lujaa? Näin metallitöiden harrastajana saisin omaan autotalliin hitsailtua, olettaen tietysti että raha tai mikään muukaan rajoittaisi tekemistä, reilun 5 metriä leveän ja 2 metriä korkean turbiinin kohtalaisella tarkkuudella (pitäisi toki seinä tai katto purkaa että sen saa ulos). Mistään ydinvoimatarkkuuksista ei nyt varmaankaan puhuta, mutta näin yhtäkkiä hihasta ravistamalla sanoisin että sitä kiekkoa voisi vieläpä pyörittää jonkun sata kierrosta minuutissa aivan kohtuudella ilman että se ravistaa itsensä ja kaiken muun ympäriltä hajalle. Ja ei tuommoisen tekemiseen kovin montaa vuotta saisi kulumaan edes yksinään.

    Sitten tietysti asia on aivan eri jos se ropeli pyörii vaikka edes 1500rpm, puhumattakaan siitä mitä vauhdit on esim. inertia-akuissa (sikäli kun termi on oikea), jolloin painotukset ja sunmuut pitää olla paljon tarkempia kuin mihin rullamitalla ja motonetin lasereilla pääsee.

    Tuossa nimenomaisessa ropelissa on toki varmasti paljon sellaista, mitä ei näin yhtäkkiä osaa edes hahmottaa ja kun en tuollaisen tekniikan parissa ole ikinä tehnyt töitä niin en edes kuvittele tietäväni kuin osasia siitä mitä en tiedä/ymmärrä tarpeeksi, saati että se mitä tiedän riittäisi edes lähtötelineisiin, mutta monenlaista valmistustekniikkaa on tullut työuralla nähtyä ja siinä valossa tuntuu jotenkin kovin omituiselta että tuommoisen osan tekeminen sillä kaikella tekniikalla mitä ihmiskunnalla on käytössään olisi jotenkin erityisen vaikea asia.

    Mutta kuten todettua, oma tietämys tuollaisista komponenteista on melkoisen hataralla pohjalla niin tyydyn näin maallikkona viisastelemaan satunnaisella keskustelupalstalla enkä ole soittelemassa TVOlle että tilatkaapa tuo roottori minulta niin tulee nopeammin valmista.




  • The actual number will be much higher.

    Ukraine reports almost 9000 tanks destroyed. Some time ago I made a rough calculation on what wikipedia lists on Russian military hardware and based on that they had around 14 000 tanks before the war started. I don’t think that even Russians themselves know how many of those are in any kind of usable and/or repairable state and which are just scrap metal laying on some field in the middle of nowehere stripped of anything useful.

    Additionally, Ukraine reported destroyed tanks in single digits per day for quite a while, but for last few days the numbers have gone up, I’d guess because of counter attacks in Kursk and/or because Ukraine is finally receiving some ammunition for their hardware. Whatever the case might be, majority of Russian tanks are destroyed anyways and I’d guess that what’s left is soviet relics and a significant portion of those are just scrap metal (which is of course a useful resource) instead of anything even close to combat ready.


  • Kyllähän siinä lähistöllä kasvaa pajua, pihjalaa ja kaikenlaista muutakin risua ihan laittamattakin ja on niitä tullut käytettyäkin, mutta varsinkaan metrin mitassa tahtoo vähän huonosti löytyä suoria ja tasalaatuisia pajuja mistä veistellä tikkuja varastoon. Lisäksi näin pimeällä ja varsinkin talvella tuossa on sitten aina oma riesansa käydä etsimässä sopiva aihio vuoltavaksi, joten jotain vähän lujempaa on hakusalla.

    Ja puutikku, vaikkei kertakäyttöinen olekaan, ei silti kovin montaa makkaraa kestä kun piikkejä pitää teroitella ja varsi heti piikkien jälkeen tahtoo hiiltyä ja lopulta palaa poikki. Ihan joka ilta ei toki laavulla tule istuttua, että ei se kulutuskaan kovin valtavaa ole, mutta yhtäkaikki varastoa pitäisi sitten uusia säännöllisesti ja niitä pajuja pitäisi leikellä vähän ajatuksen kanssa että kasvusto ehtii tuottaa riittävästi aihioita ennenkuin kasvavat liian isoksi ym niin tuosta tulee äkkiä yksi kotityö lisää ja niitä tahtoo omakotitalossa olla jo aivan tarpeeksi.

    Täysin käypä vaihtoehtohan tuo toki on, mutta omaan makuun etenkin näin ruuhkavuosien keskellä sopii paremmin ajatus siitä että noihin käyttää kerran vähän enemmän aikaa ja vaivaa ja sen jälkeen asiaa ei tarvitse enää ainakaan kymmeneen vuoteen murehtia.



  • more specific to a subset of people who have time to bother

    And that subset of people needs to have at least some kind of mindset to learn the viable minimum skills to even start with and a will to learn more and more and more. I’ve done various kinds of hosting as a career for couple of decades and as things change I’m fighting myself if it’s worth my time and effort to keep my home services running or should I just throw money to google/apple/microsoft/whoever to store my stuff and manage my IOT stuff and throw the hardware into recycling bin.

    I have the skill set required for whatever my home network might need up to a point that I could somewhat easily host a small village from my home (money is of course a barrier after a certain point), but I find myself more and more often thinking if it’s worth the effort. My Z-wave setup needs some TLC as something isn’t playing nicely and it causes all kinds of problems with my automations, my wifi network could use a couple of sockets on the walls to work better, I should replace my NVR with something open source to include couple of more cameras around the yard and have better movement recognition and cameras should go to their own VLAN and so on.

    Most of that stuff is pretty basic to set up and configure (well, that z-wave network is a bit of it’s own thing to manage) and it would actually be pretty nice to have all the things working as they should and expand on what I have to make my everyday life even more simpler than it already is. But as there’s a ton of things going on in life I just rather spend few hours gaming from my sofa than tinker with something.

    That’s of course just me, if you get your reward and enjoyement on your network then good for you. Personally I think I’ll keep various things running around, but right now in this place I’m at, the self hosting, home network and automation and all that is more of a chore than a hobby. And I’m pretty sure I don’t like it.


  • Omakoti täälläkin ja pörssissä on oltu jonkin aikaa. Kesäaikaanhan tuo on ollut mukava kun pörssihinta on aivan nollissa, nytkin sahko.tk näyttää että 28vrk keskiarvo on alle 4 senttiä, mutta talvella pitää seurata aika tosissaan että mitä se milloinkin maksaa ja ohjata lämmitystä (osin automatisoidusti) sähkön hinnan mukaan. Ei tuolla ihan ihmeisiin tietysti pysty kun ei talossa varaavaa massaa kuitenkaan ihan älyttömästi ole mihin pistää halpoja watteja talteen, mutta pörssiin siirtyessä silloinen yhtiö tarjosi mukavaa 28 senttiä + verot (tai jotain tuonnepäin) niin valinta oli aika yksinkertainen.

    Pitäisi tieten viitsiä huudattaa noita toimittajia että mihin hintaan saa ihan oikean kiinteän sopimuksen ilman mitään kulutusvaikutuspelleilyä, ne kun on paitsi hemmetin epäselviä laskukaavoiltaan niin myös ainakin uutisoinnin perusteella vaikutuksetkin jää lähinnä myyntitykkien käsienheilutteluksi.



  • Medvedev found keys for the booze cabinet again? They seem to happily forget the fact that Moscow is well within reach of multiple Nato countries by now. Obviously a ton of things need to change before anyone with a gun is standing on a red square, but Finland, Sweden, Estonia and Poland (among others) are quite capable of hitting the Kreml (in theory, and in practise if needed) with fighter jets in less than 30 minutes. Additionally their ports opening to gulf of Finland are in reach of both Finns and Estonians with traditional artillely, and at least we in Finland are pretty capable and accurate with our hardware.

    So, even if they find some old soviet relic still functional, Nato has multiple options to level multiple cities at Russia before their missile hits the ground. Nuclear attack against Ukraine would of course be a humongous tragedy with terrible price on civil casualties, but I’m pretty confident that it would be the last thing the Russia we currently know would do as a country.

    As far as I know it is the default way of handling multiple DNS servers. I’d guess that at least some of the firmware running around treats them as primary/secondary, but based on my (limited) understanding at least majority of linux/bsd based software uses one or the other more or less randomly without any preference. So, it’s not always like that, but I’d say it’s less comon to treat dns entries with any kind of preference instead of picking one out randomly.

    But as there’s a ton of various hardware/firmware around this of course isn’t conclusive, for your spesific case you need to dig out pretty deep to get the actual answer in your situation.

    have an additional external DNS server

    While I agree with you that additional DNS server is without a question a good thing, on this you need to understand that if you set up two nameservers on your laptop (or whatever) they don’t have any preference. So, if you have a pihole as one nameserver and google on another you will occasionally see ads on things and your pihole gets overrided every now and then.

    There’s multiple ways of solving this, but people often seem to have a misinformed idea that the first item on your dns server list would be preferred and that is very much not the case.

    Personally I’m running a pihole for my network on a VM and if that’s down for a longer time then I’ll just switch DNS servers from DHCP and reboot my access points (as family hardware is 99% on wifi) and the rest of the family has working internet while I’m working to bring rest of the infrastructure back on line, but that’s just my scenario, yours will most likely be more or less different.


  • En minäkään tiedä alkon myymälöiden liiketoiminnasta mitään, mutta sinne on kumminkin viinat, viskit, rommit ja aika paljon muuta jäämässä sen asiantuntemuksen ja muun kanssa. Ihan yhtälailla ainakin paikallisessa alkossa on tarjolla tuplapukkia ja muuta olutta mitä saa siitä viereisestä prismastakin, hintoja en ole vertaillut vaan veikkaan että s-mafia myy halvemmalla.

    Toisaalta jos merkittävä määrä pienempien kuntien alkoista menisi kiinni niin ehkä sitten saataisiin alkoholin etämyynti jotenkin järkeväksi, mutta en taida pidättää hengitystä tuota odotellessa.




  • losing 1380 personnel, but only 1 tank

    That’s what I’ve been following too. And additionally, based on quick’n’rough estimation from wikipedia numbers, artillery reserves are pretty much depleted too, so Russia is fighting on what ever soviet era relics they can refurbish and what they can manufacture/buy. I don’t think they’ll have short of ammunition any time soon, but diminishing numbers of barrels should start to show up on these statistics ‘in the near future’, whenever that might be.


  • Well, on channel description he clearly states that those are only motorized recreations of suggested perpetual motion machines. But on individual videos that info doesn’t seem to be that readily available, so it’s not totally wrong to say that the whole channel is a lie, but strictly speaking not excactly correct either.

    Some of those gadgets would make a nice desktop toy, obviously with a usb power brick or batteries.


  • Back in the day with dial-up internet man pages, readmes and other included documentation was pretty much the only way to learn anything as www was in it’s very early stages. And still ‘man <whatever>’ is way faster than trying to search the same information over the web. Today at the work I needed man page for setfacl (since I still don’t remember every command parameters) and I found out that WSL2 Debian on my office workstation does not have command ‘man’ out of the box and I was more than midly annoyed that I had to search for that.

    Of course today it was just a alt+tab to browser, a new tab and a few seconds for results, which most likely consumed enough bandwidth that on dialup it would’ve taken several hours to download, but it was annoying enough that I’ll spend some time at monday to fix this on my laptop.


  • I mean that the product made in here is not the website and I can well understand that the developer has no interest of spending time for it as it’s not beneficial to the actual project he’s been working with. And I can also understand that he doesn’t want to receive donations from individuals as that would bring in even more work to manage which is time spent off the project. A single sponsor with clearly agreed boundaries is far more simple to manage.

    The threat model seems a bit like fearmongering. Sure, if your container gets breached and attacker can (on some occasions) break out of it, it’s a big deal. But how likely that really is? And even if that would happen isn’t the data in the containers far more valuable than the base infrastructure under it on almost all cases?

    I’m not arguing against SELinux/AppArmor comparison, SElinux can be more secure, assuming it’s configured properly, but there’s quite a few steps on hardening the system before that. And as others have mentioned, neither of those are really widely adopted and I’d argue that when you design your setup properly from the ground up you really don’t need neither, at least unless the breach happens from some obscure 0-day or other bug.

    For the majority of data leaks and other breaches that’s almost never the reason. If your CRM or ecommerce software has a bug (or misconfiguration or a ton of other options) which allows dumping everyones data out of the database, SElinux wouldn’t save you.

    Security is hard indeed, but that’s a bit odd corner to look at it from, and it doesn’t have anything to do with Debian or RHEL.
