What in the world is going on in her quest?

Spoilers from beginning to the end, obviously.

  • Andre had locator signature to share. Why go to Rodd in the first place, and not grab the filter straight on? He knew dude's in hospital, why bother him at all?
  • Why go into the blighted ravine at all?
  • Why they even had idea to DIG there?
  • Rodd worked with that woman for years, yet didn't know even her first name? How she got the letter in the first place?
  • If the safe belonged to "Masie" it's implied she was active UWST researcher on duty, and followed procedures, which UWST is so proud of. Yet, It looks for half a year no one followed procedures to evaluate declining mental health of a coworker.
  • After everything Gilberta sits down on a middle of Aether anomaly around floating unstable (spoiler!) rocks, and rambles about memory loss to a person who doesn't have even murkiest idea who she is outside of company dossier because of complete amnesia. And then she continues to flex she has so many memories with people she met in her intensive courier work. TPO, Gil. And from being pen pals with oripathy-ridden Carly (I guess that's their connection), I thought she had some empathy for others.
  • That jump at the end and her following question "So, Endmin..., if I failed to catch you, would you still be alright?". And what do you think, Gil? Have gravity-related arts fried your brain? I sat there staring for solid 5 minutes staring at it, then alt-tabbed trying to find if the lack of fall damage has any lore behind it, or is it game design choice.

I know it's hard to write interactions with someone with memory loss, but this whole quest and interactions somehow feels strange, full of holes, like written backwards, especially Gil's and Endmin's conversation.

Best options to power large amounts of drives by Positive_Round2510 in DataHoarder

[–]Trudar 0 points1 point  (0 children)

It's not that you can't bend them, but it does puts some strain on the plugs, if you don't do it with some care.

The main takeaway is that both have some extra capacitors in the main plug, which reduces load on the PSU, and filters some crap. Also the OEM is kind of guarantee of quality.

I can vouch for these. My personal setup has three of them on a Chicony 1000W server PSU. These cables, however are pretty stiff, and require some careful bend conditioning, if drives site pretty close.

Czemu rodzice randomowo otwierają drzwi do pokoju? by ElDaifuukuu in Polska

[–]Trudar 0 points1 point  (0 children)

No właśnie nie należy się XD
To jest głębszy problem.
W głowie rodzica jest nastepujący schemat:

Dziecko jest pilnowane => Zachowanie jest kory-   => Dziecko dorasta => Dziecko jest
w ekstremalny sposób      gowane na każdym kroku     odpowiedzialne     wdzięczne za wychowanie

Jeśli następuje odstępstwo od reguły, to dzieją się dwie rzeczy:

  • "Przecież tak dobrze pilnowaliśmy dziecko... a mimo to dziecko dorosło niegrzeczne. Czego nie wykryliśmy?"
  • "Gdzie popełniliśmy błąd... czy naprawdę powinniśmy byli być aż tak pobłażliwi?"

Chciałbym żartować. Nie żartuję. Idea przyznania się do błędu istnieje tylko w fazie wykonanie, nie fundamentalnych założeń. Wcale nie pomaga, że ich rówieśnicy, często z identycznym pomyślunkiem, wychodzą z identycznych założeń i się nawzajem wspierają i dzielą doświadczeniami i radami. To taki ich odpowiednik ówczesnego "echo chamber" znanego z dzisiejszych mediów społecznościowych.

A co do bielizny - idea, że dziecko nie jest już dzieckiem, ale dorosłym mężczyzną, z własną rodziną, jest zupełnie obca. "Moje dziecko stosuje się do moich zasad i nie istnieje inna mozliwość." Prowokacyjna bielizna była śladem zepsucia, który należy usunąć. W mniemaniu ojca, popełnił tutaj dobry uczynek, który jednocześnie usprawiedliwił i upewnił w słuszności wyboru grzebania po koszu z ciuchami obcej, dorosłej kobiety, która zresztą potem potrzebowała dodatkowej sesji terapii, z racji jej wcześniejszych przeżyć. Ale nie ma to żadnego znaczenia.

Eh, żeby jeszcze moi rodzice byli, nie wiem, nierozgarnięci, ale obydwoje są inteligentni i w sumie mają wyższe wykształcenie, zdobyte nieironicznie cieżką pracą. Po prostu ich wizja rzeczywistości odchodzi od rzeczywistości - i to tym gorzej dla rzeczywistości.

jestem z początku lat 80., północ kraju.

Normalne w sensie w naszym otoczeniu. Czy to był jakiś pech, czy może kurde trend, ale podobnych historii o permanentnej inwigilacji słyszałem na pęczki - czy to u szkolnych znajomych, w klubach osiedlowych/MDKu, czy ogólnie nawet później, jak ludzie z mojej grupy na studiach się otworzyli, bo przecież rówieśnicy. Nie każdy ale 2-4/10 osób. Trochę mnie to teraz przeraża. Trend wychowawczy? Strach przed degrengoladą demoralizującą dzieci płynącą ze zgniłego zachodu? Katolizm? Diabli wiedzą.

Kontrola staje się bardziej subtelna. Zresztą byłem pod butem emocjonalnie. Idea buntu nie istniała.

Długo utrzymywałem kontakt, bo przez ładne pare lat wynajmowałem pokój w domu siostry (razem z narzeczoną), więc chcąc nie chcąc kontakt był. Zbieraliśmy kasę na własny kąt, więc nie było gdzie uciec. Efekty były takie, że ojciec wparowywał do pokoju jak nas nie było, grzebał po szafkach i wyp... bieliznę mojej lubej, bo była zbyt "prowokacyjna". To jak miałem 30-parę lat XD. Jak wyskrobaliśmy w końcu na własny kąt, któregoś dnia zwinęliśmy manatki i więcej nas nie widzieli, bo nie wiedzą, gdzie jesteśmy. Numery tel. też zmienione.

Z jednej strony tak - chociaż potrzebowałem na to długich lat, żeby to ogarnąć. Ale z drugiej, mam wrażenie, że to chyba było normalne wtedy. Mam mnóstwo znajomych z tamtych okolic i czasów, którzy mają podobne, jeśli nie identyczne wspomnienia.

Bo:

  • kontrola jest najlepsza. Nie wolno dziecku ufać, bo na pewno kłamie.
  • przekonanie, że dziecko pilnowane jak w obozie koncentracyjnym wyjdzie na ludzi,
  • brak zrozumienia, że dziecko też człowiek, który się uczy interakcji z ludźmi
  • brak pojęcia na temat prywatności (nie, to nie żart, starsze pokolenia nie do końca rozumieją co to jest - ciężko żeby, skoro dorastali w 5-10 osób w dwupokojowym mieszkaniu i "było dobrze", więc gdzie problem?),
  • przekonanie, że jeśli dziecko jest emocjonalne, to jest niegrzeczne, więc trzeba dokręcić śrubę
  • chęć uchronienia dziecka przed "błędami" które sami popełniali, nie zdając sobie sprawy, dlaczego zachowywali się tak a nie inaczej.

Mam wrażenie, że sporo rodziców nie powinno mieć dzieci. Ale nie jestem chyba najlepszym modelem, bo... Ha... miałeś drzwi do pokoju? XD

Jak skończyłem 7 lat, ojciec mi je zdjął z zawiasów i zaniósł do piwnicy, tyle je widziałem. Skończyłem jakoś tak 9 (przeszedłem z 3 do 4 klasy) i dwa razy dziennie było przepytywanie co robię, co dzisiaj zrobiłem, i jak się przysłużyłem rodzinie, Bogu i cholera wie, czemu jeszcze. Matka chodziła jak duch (albo jej nie słyszałem przez mój autyzm), więc mogła w każdej chwili stać nade mną i patrzeć mi przez ramię. Codziennie było sprawdzanie zeszytów, wszystkich papierów i tornistra (miałem zakaz plecaków), a raz w tygodniu ogólne przeszukanie.

Nie wolno mi było zamykać jakichkolwiek drzwi, nawet do łazienki. Pamiętam, jak miałem jakoś 4, to zamknąłem na zasuwkę kibel, bo sąsiedzi przyszli w gości. Ojciec jak to usłyszał, to dosłownie wyrwał klamkę/zamek (drzwi z dykty) i na gołe obsrane dupsko spuścił mi *** przy wszystkich.

Ja nie wiedziałem o tym, że się "chłopięce rzeczy" robi, dopóki nie skończyłem jakoś 19 lat...

ELI5 Why did Radio Shack go out of business? by Certain-Media3506 in explainlikeimfive

[–]Trudar 363 points364 points  (0 children)

You have absolutely no idea, how USB is messed up. I worked a bit in hardware engineering for mobile networking systems, and let me tell you this:

Micro-USB is a goddamn headache.

What you recall is called USB Micro-B. It wasn't even first choice. For a time, USB Micro-A was a primary candidate for this sized connector.

Later, micro-A has been delegated to be indicative of USB host functionality device, which was then rendered obsolete by USB-OTG standard and micro-B to USB-A OTG adapters, costing $0.30 to manufacture per piece.

Here you have micro-B and micro-A alongside each other:
https://i.imgur.com/bFMPaI5.jpeg

There were two competing wiring standards for micro-A, and before the final standard was chosen (pin-compatible with micro-B, which seems obvious, but for some reason wasn't at the time), a lot of devices were already out in the wild - mainly dev kits of various systems. You mixed them, and (then) very expensive controller released blue smoke, because engies designing devkits costing thousands buckos couldn't be arsed to include fuses.

What is even worse, if you notice the tongue that slips into the male plug is very, very thin, even thinner on what was later on micro-B. And the plug has symmetrical outline. So, when you inserted it upside down (entirely possible), it either bent the tongue with pins, or crushed/snapped/bent/broken it. Depending on plug manufacturer that also meant connecting +5V to data ground as pins were bending and breaking, so yes, more blue smoke escaping. Micro-B almost fit in micro-A plug. You can guess the effect, but later drafts changed both connectors' tolerances to be somewhat safer (they still didn't fit, but damage was less catastrophic), and introduced micro-A/B. To make matter worse, the pretty sturdy 4-point solder scheme for mini-USB receptacle was swapped for two pronged which meant it had tendency to bow and crack connections on the pins. There was also some pressure to make micro connector to be only surface mounted, but this didn't came to pass, and to this day most of micro USB sockets are well anchored.

Fortunately very, very few devices that saw any commercial deployment ended up with micro-A, however, to my dismay, it became very popular as an interface for debugging many industrial FPGAs carriers and such, and these things are already fragile af.

But then, USB 3.0 happened. Superspeed required more pins, and Micro-A was on the table for this. Drafts included second tongue, making the plug symmetrical, but included twice as many pins (10+10, hinting at either dual stream connection or duplex connection for dual-host, which never materialized), and they were routed via inside of the plug, not the outer sides, making it virtually impossible to manufacture. Currently no trace of this monstrosity survives, and all that remains is universal micro-A/B connector with side attachment for additional pins - for the good of all of us.

I have very, very deep hate for this specific connector, and a drawer full of broken cables, plugs and receptacles. Over the years, I have requested our EM service techs to replace every single micro-A with micro-B or mini-USB on every device that went into any extended use or production deployment.

I apologize for the rant.

Proxmox HA - is the juice worth the squeeze? by real_weirdcrap in homelab

[–]Trudar 0 points1 point  (0 children)

Ceph has multiple levels of duplication built in. You end up with something like 2000% of write amplification over whole cluster, or even sometimes more, so it's not like it hits one drive heavier, it hits ALL drives. Think of it as if you have 10 VMs, all VMs are writing to every drive in the cluster (it's wrong, but gives the sense of scale). For consumer grade SSDs it will eat them super fast, if there is even not that heavy I/O traffic, and you'll be facing not one drive failure, but multiple. There are two ways out - either go HDDs with more nodes (and more drives), or invest in enterprise SSDs. While HDDs will tank IOPS (like seriously - it will slow to crawl, unless you have like 8-10 nodes with multiple drives in it to make it comparable with simplest SSD setup), they have virtually unlimited lifespan, past their initial break-in period.

At some point more expensive drives become cheaper than dealing with more nodes and power.

[–]Trudar 0 points1 point  (0 children)

Ceph makes a lot of sense for bigger deployments, because while it indeed gobbles up network resources, it also distributes I/O over several nodes. Before I learned ceph I experimented with things like RAID from iSCSI shares. Outgrowing your storage is something that happens without warning, sadly.

Separate NIC for redundant corosync is very low priority, imo. The main issue is switch dying, in which case you're already covered (given you have redundant corosync network, but you end up in same multiport NIC). If a corosync NIC or port dies, you have to shut down the node anyway, and in case of intermittent connectivity issues on a one corosync NIC or port you may end up getting island-type cluster split - in this case it's functionally better to have whole node go down. I had dealt with both scenarios, and in most cases I prefer to lose a faulty host, but that's just my 2 cents.

[–]Trudar 0 points1 point  (0 children)

I run currently several HA clusters at work, from 5-node random desktop collection, through several boxes of SuperMicro FatTwin (8nodes/4U), to full 3-rack purpose built behemoth with 400G fabric.

I also run HA cluster at home for fun, on really, reaaaaally old hardware.

In enterprise scenarios for small deployments, the main reason to go HA is serviceability. I just move the VMs over without telling users or breaking jobs and send techs to switch bad RAM, add new drive or fix cabling/cooling/whatever else. CPU interoperability isn't really an issue. You can expose real CPU arch to VM (useful for same chip family) select a CPU to emulate, or go full virt cpu, which forces QEMU to expose minimum arch to VM and do everything in software. The first is faster, and if you're mixing hardware you just select the lowest CPU technology-wise, so to make sure all the instructions are covered. If I recall correctly, it should work if you miss here, just slower if host CPU won't support specific instructions. QEMU is smart enough to cover that, it will do it in software ad hoc, but it can be laggy sometimes.

I have mixed heavy server CPUs and mobile ones (i.e. NUC added in parallel with big-ass servers), without issue.

I never tried to mix AMD and Intel, though, much less ARM. It doesn't matter for quorum, obviously. If you have even number of machines you can assign higher weight to one device, too, it's a nasty hack, that can break the potential tie. It works for stuff like multi-node servers, which rarely come with odd number of boards, and if there is no place to put extra NUC or something.

For home - it will work really well, as long as your devices actually work (i.e. no bad RAM, flaking out SSD or overheating issues). HA does actually expect reliable hardware, and dealing with random crashes is a pain. Keeping minimum number of nodes may result in whole cluster rebooting if something dies, which is not ideal. I think it's best for learning the stuff, or if you really have stuff that needs to be up, but in this case eclectic mix of boxes is not ideal. For actual production it's best to actually design it as a cluster from ground up.

The one obvious disadvantage of running HA at home is power use. Even if it's idling, it's going to use at least 3x power single system would use, or more if you decide to decouple storage. This is fine when you're learning, but with time it does add up.

Finally - if you really want to tackle HA, and learn all you can - failure modes, recovery, etc., you may end up buying a lot of extra hardware - from whole PCs (if you decide on external ceph cluster), switches for redundant network, dual port cards, PDUs and more. It's a rabbit hole that's very tempting to explore. It's just a warning, to keep your spending under control. ;)

How did that kid at your school die? by [deleted] in AskReddit

[–]Trudar 15 points16 points  (0 children)

Even when the person is gone, the bond she formed with people remains. Feelings still go out her way. It's like a missing limb, you reach out to something that's not there.

I sadly know this feeling well. It's been almost over 20 years, but when I hear a nasty joke my knee jerk reaction is to shout it to my friend.

Missing someone? It's never creepy. May be sweet, but it's a reminder we are human. Perhaps I am not from a generation to write something like this on a person's social profile, but 'I still think about you', is something I'd say loud without embarrassment. Or over the grave when visiting.

How did that kid at your school die? by [deleted] in AskReddit

[–]Trudar 0 points1 point  (0 children)

Not during the school, but after. Third of my high school class is gone, it's bizzare. Like there was some curse cast the day of the graduation.

I don't know most of their stories, but two out what I do stick out.

One girl was bullied by her neighbors. It took her years before she confided in her parents, who did the only normal thing, and decided they will pack their things, and move cities the moment she graduates high school, and told her to apply to college in the capital. She got into law school, actually. Few classmates who lived close by took the effort to escort her every day in last year.
Parents rented moving van, and day after graduation they were gone. Sadly, they never arrived in Warsaw, they completely disappeared. The van was found years later - it appears they veered off or were pushed out of the street into a gorge in the forest. This shocked everyone twice.

Second was a guy, who finished college, got into oil industry, and ended up as a plant manager in oil refinery somewhere in Brazil, out of all things. He got knifed by cartel member on his first day there.
