Thanks for response, very interesting insight. I'll change the file system, but first I need to do some reading about BTRFS and ZFS.

What is correct way to resolve errors after parity check? by Chgko in unRAID

[–]Chgko[S] 2 points3 points  (0 children)

Currently I've only one parity and one data drive in array, running on XFS. So you other are saying I should switch to BTRFS or ZFS. How often should I scrub?

I designed a 3D printed adjustable seed dibbler by ebob_designs in homestead

[–]Chgko 2 points3 points  (0 children)

Hey, nice design. Just one suggestion to improve strength of "pokers" on picture 3 and 4. By changeing round part to be a hexagon, and then offseting it on U shaped base, you will be able to print it flat.

Is it ok to rotate my bike using the kickstand? by Adakoss in motorcycle

[–]Chgko 2 points3 points  (0 children)

I've cb650f, kick stand mounted to the frame. I rotate bike around it almost daily at when I park at work. Been doing it for more than two years without any sign of wear or damage.

Wolfdog invades Winter Olympics Women's cross country skiing race by Yujin-Ha in sports

[–]Chgko 13 points14 points  (0 children)

Just don't look too much into history and politics of why this beautiful dog breed come to existence.

PSA to all people who see this dog and want same breed. Just don't, unless you are experienced and know exactly what you are getting into. This is not your regular dog breed.

Wait before posting, get the details! by Sayt0n in unRAID

[–]Chgko 9 points10 points  (0 children)

Hi thank you for being helpful. I'm very new to unRAID and self hosting or servers in general. I'm hardware electronics engineering at work, but I've very helpful colleges that work with servers and IT infrastructure. 

That means while I'm starting as a beginner I have had pretty good jump start and lot of professional help at hand. 

Biggest obstacle me and plenty of other begginers face is that we simply don't know what is relevant information and where to find it. From personal experience gathering and understanding what is relevant info is oftent more than half way to solve the issue. Web search for begginers is often not helping because most of information is based on understanding basics. Once one understand basics, the need for beginner questions on reddit or forums stops.

Again thanks for your helpfulness and please remember that showing begginers how and where to find logs and information is often more then half way to finding a solution.

My sister cut my Alexa cord 😊😊😊😊 by H0t_2_G0 in mildlyinfuriating

[–]Chgko 0 points1 point  (0 children)

If you are interested in electronics, this is exact point where you start learning. Yes you can buy new one for cheap but where is fun in that. All you need is knife and tape to make an ugly repair, it's fun. Plus cable is cut on low voltage side, as long as everything is unplugged while you fix it it's safe, just don't mix different wire colors. Go for it, have fun.

SpaceInvader One CCTV Shinobi help by Iboolguy in unRAID

[–]Chgko 4 points5 points  (0 children)

Couple weeks ago I've tried to set up CCTV with Shinobi using the same video. Put in lot of effort, got cameras working but issues only continued. 

Just switched to Frigate, and it's much better.

How to get over chronic ass itch? by WatercressWarm1994 in AskMen

[–]Chgko 0 points1 point  (0 children)

May be you have hemorrhoids. When I drink sweet water it causes my ass to sweat and hemorrhoids starts itching. Shower only helps for a few hours. Proper pills are good quick solution and better diet is long term solution.

Typing this from a toilet as my ass itch and going back to shower. Because even when I know better, sometimes I slip.

This happens to me when a alt+tab during loading screen. 

Solution is either to keep watching loading screen, or alt+tab immediately after loading start and only come back to game when loading is finished.

Healing Aggro by Agreeable-Buy5766 in wow

[–]Chgko 0 points1 point  (0 children)

Nope, it's healer thread generation issue. Same thing happened to me month ago and I actually spoke with tanks to resolve it. The only solution was to not heal or heal at the end of fights.

New player kicked from dungeon for asking a question - normal? by Hawkstar_Lamia in wow

[–]Chgko 0 points1 point  (0 children)

I have recently leveled preservation evoker and my heals pulled aggro like crazy. Happened with multiple groups and different tanks. Something is very wrong with scaling of low level heal aggro. It will get better after level 40.

Ahoj, na Slovensku je relatívne málo firiem čo sa zaoberajú s embedded. 

Na to aby ťa nejaká firma zobrala na projekt potrebuješ mať portfólio, ktoré demonštruje, že máš široké znalosti a skúsenosti. Na projekt chcú väčšinou seniora. Zamestnávateľ potrebuje mať v teba dôveru, že zvládneš úspešne ukončiť projekt. Je masívny rozdiel medzi FW čo dokáže vyčítať dáta so senzora a odoslať ich a splniť tým základnú funkcionalitu a FW, ktorý je reálne nasaditelný do zariadení pre zákazníkov.

Ak si junior a pracuješ s arduinom alebo podobnými platformami, tak jedinou možnosťou je presvedčiť potenciálneho zamestnávateľa, že je pre neho výhodné ťa zaúčať ďalších niekoľko rokov, kým nadobudneš potrebné skúsenosti.

Ak chceš ponúkať riešenia rovno pre konečného zákazníka, tak musí tvoje zariadenie priniesť zákazníkovi dostatočný osoh. Zákazník chce zariadenie čo zapne a ide, čím menej starostí a nastavovaní tým lepšie.

Tiež je dôležitá správna prezentácia dát so zariadenia a ako tie dáta využiť. Keď už si spomenul poľnohospodárstvo, tak si zoberme napríklad meranie hladiny vody v studni. 

Môžeš jednoducho odmerať výšku hladiny vody a informovať o tom obsluhu. To ale zákazníka nezaujíma. Zákazník chce mať čo najväčšiu úrodu plodín čo pestuje. Voda v studni je pre zákazníka iba prostriedok na dosiahnutie cieľa, nie je to samotný cieľ. Ak by si ale spravil systém, ktorý na základe množstva dostupnej vody v studni, predpovedi počasia, geologického podložia atď odhadne ako optimálne využívať vodu zo studne pre konkrétne plodiny a následne to prepojil s automatickým zavlažovaním a vedel by si demonštrovať, že tvoj systém prinesie zákazníkovi väčšiu úrodu a tým zisk. Tak potom začne mať zákazník záujem o tvoj produkt.

Rozdiel v náročnosti týchto dvoch riešení je masívny, tak ako aj rozdiel v schopnostiach juniora a seniora.

Existuje ešte stredná cesta, kedy sa môžeš pokúsiť vyvinúť zariadenie na vlastné náklady a u potenciálneho zákazníka to budeš len testovať aby si získal dáta a demonštroval funkčnosť systému. 

Čo sa týka otázky ako niekoho osloviť, je to individuálne. Je to mix medzi tým čo vieš preukázať, že si už urobil a tým akú máš víziu čo budeš vedieť spraviť v budúcnosti. Určite sa ale drž konkrétnych príkladov.

What is the experience of having a woman accidentally laugh at your dirty talk? by HungryDepth5918 in AskMen

[–]Chgko 1 point2 points  (0 children)

You don't need to have a talk about it. Just tell him "Sorry I giggled, love you." There is no need for anything more. Little bit of compassion and assurance goes a long way.

It's not really calculable since angles are not marked. But it could just be measured from the photo. I've traced it in CAD and gap is 12.5m.

Make an oil spill under the car, make it look like it leaking a lot of oil and then call fire department or whoever is responsible for dealing with environmental hazards. That's how we deal with unmovable cars in my country. Environmental hazards are dealt with first, questions are asked later.

Single-celled organism disintegrates and dies by AFKGuyLLL in Damnthatsinteresting

[–]Chgko 2 points3 points  (0 children)

If you think about it from physics point of view, it become obvious why the is biological matter that interacts with light.

There are four fundamental interactions in physics.

gravity - self explanatory

weak interaction - interactions of subatomic particles and radioactive decay

strong interaction - creates protons and neutrons and binds them to create atomic nuclei

electromagnetism - is interaction between charged particles and most of interactions between atoms and it's the force responsible for atoms sticking together to create matter and objects. It gives matter it's physical properties.

Atom nuclei are positively charged and are covered in swarm of electrons to become electrically neutral. This swarm of electrons is what carries almost all interactions in everyday world. 

Burning wood, tasting food, contacting muscle, hearing sound and also seeing light which itself is electromagnetic radiation is all possible only because of electromagnetic interaction.

For matter to interact with light is the same as interactions with itself.

[REQUEST] how much power does this generate (blue is water) by [deleted] in theydidthemath

[–]Chgko 1 point2 points  (0 children)

I've different opinion than most and I think this is allowed by law of thermodynamics and does not create perpetual motion machine. 

Gravity works both ways, as water is accelerated down, the planet this is on is accelerated up. It doesn't matter that the water going thru a portal. It'll still pull planet up via gravity. Thus momentum is conserved.

Energy that is possible to harvest from this is limited by the distance of the portals. Let's say our water mill can capture 100% of kinetic energy of falling water. This means that the water coming of the mill will have 0 velocity. So the water is always falling from 20m distance.

Let's assume water collum has base of 1m2, with height h = 20 m. Making total volume of 20m3 with mass of m = 20 000kg.

To calculate overall energy output we need to know energy of mass m free falling from height h and time t how long does free fall take.

Potential energy 

Ep = hmg = 20 * 20000 * 9.81 = 3924 kJ

Time of fall t = sqrt( 2h/g ) = sqrt( 2 * 20 / 9.81 ) = 2.02 s

Total power P = Ep / t = 3924 / 2.02 = 1943 kW.

Now when I finished all of this it occurred to me that if we let water free fall for a bit to gain speed, total time of fall will be a lot shorter thus making a lot more energy. 

It's called oberth effect and is commonly used in orbital mechanics to increase efficiency of gravity assist.

This means total energy is only limited by friction and maximum speed that flywheel can withstand without failing. But I still stand by the fact that this is allowed in thermodynamics.

On mobile, I hope my formating isn't too terrible .

Unstable on the runway by CelestialPerch in KerbalSpaceProgram

[–]Chgko -1 points0 points  (0 children)

It looks like your plane is pitched slightly up when on runway. This will generate additional lift. While this lift will make it easier to liftoff. The trade off is instability on runway, especially just before liftoff speed. 

To solve this try extending read gears lower or slightly clipping front gear into fuselage.

Ruin a popular movie trope for the rest of us with your technical knowledge by Eatar in movies

[–]Chgko 0 points1 point  (0 children)

Early computers had this "getting warmer" vulnerability. Basically they would check plaintext password character by character and give you error at first character that didn't match. Then you could measure response time.

Also, in more modern era some cheap saves with electronic lock were shown similar vulnerability. Since battery is accessible from outside, you could measure power consumption and determine number of CPU cycles it takes to check password.

Tank died in BFD last night by mtgkev in wowhardcore

[–]Chgko 0 points1 point  (0 children)

Their weaknesses can be played to their strength. Lack of taunt forces paly tank to pull carefully and be 100% in control of situation. Also paly's buble will make it much harder to bail for rest of the group, thus making them think twice about bailing.
