Couldn't find anything relating off a brief look; Is there a thread dedicated to Roomba modding? I feel like tinkering with my soldering iron and making my roomba smarter at navigation

MTV Crib Death posted:My FPS has suddenly gone to poo poo and I'm tearing my hair out trying to figure out why. I even did a fresh OS install hoping that it would work, but I'm running into the same problems. Do you have some sort of paging file setup, is your primary HDD full? Sounds stupid I know, but worth a check

Ciaphas posted:If I can figure out the timings, speed, and CAS latency (Speccy will tell me that, right?), I can buy RAM from whatever brand and it doesn't matter, right? It's one of those technical grey areas, as others stated. You COULD buy 2 different 4gb sticks from 2 different manufacturers, and the chance of them all working together perfectly is a healthy 15%. Unless the ram you bought is super special I'm sure you can find the same ones you already have for sale, either brand new or on ebay. TL:DR Think of RAM like spark plugs for your car, mixing and matching is just a recipe for headache

LingeringDoubt posted:I've got a question about USB hubs. I've recently purchased a Thrustmaster HOTAS so I can pretend to be a pilot while I surf porn (like real pilots do) along with a set of rudder pedals. I've run into something that I should have anticipated but didn't, and that's a shortage of USB ports. Alereon posted:USB 2.0 is 480 megabits per second, even with overhead that's easily 30MB/sec, which is more than enough for nearly anything. Based on a quick Google USB hubs seem to add much less than 1 millisecond of latency, though I'm sure there exists some hub that is worse, your average generic Chinese hub should be just fine. Like most simple devices you'll see a reliability curve where the cheapest devices don't work for poo poo, slightly more expensive devices work great, and paying any more than that doesn't get you much more. I'd get a Rosewill hub from Newegg that has a lot of sales and 4-5 eggs, it's hard to go wrong considering the price. Only thing I didn't see mentioned is powered versus unpowered hubs For something like running your HOTAS it's probably a good idea to get a powered hub, don't rely on the power via the USB port to keep everything running. I have a 4 port hub with my pedals, trackir, and X-55 plugged into it, and it performs quite well Although sometimes I have to unplug and replug the power on the hub to get it to pickup the devices

Not a hardware question really but... I use chrome and noticed the past few weeks I keep seeing the little yellow triangle with exclamation mark for my profile I'll click the dialog, sign back in, use my auth code sent to my phone, and it fixes everything 5-10 minutes later the the triangle is back, and it's asking for authorization again. Read a few people having the same problem, and completely signing out of the account and back in usually fixes it, but not for me! It seems like everything works fine, I can see my browser history on my phone etc, so its obviously keeping the account synced.. thoughts?

I just got my new system built and running the other day, its a 4790k cpu on a Sabretooth MKII board Everything is looking great, temps idling in the low 30's across the board However the Vcore temp is around 60-62 while sitting in windows... that doesn't seem right?

Khanstant posted:Yesterday morning when I turned on my computer it was giving me an error, ran diagnostic whatever, and its not detecting my hard drive, presumably because its dead or something. Especially since its kind of a mysterious computer, and the hard drive situation was actually two hard drives configured in a RAID, only one of the hard drives was smaller in space and was actually a laptop hard drive in some weird exoskeleton the size of a normal HDD. Anyway, this basically means my data is all gone and computer broken so I should just go ahead and build a new one, right? So did you disconnect the raid before, or is it still configured as such? Because that would mean you data is on at least 1 of the drives

I have need for a mini pc/server, as small as possible but able to run Windows, IIS, SQL, and that sort of thing without any issues. Also ability to raid a few drives would be nice, drives can be external to make the form factor not a problem I found some really mini pc's on amazon etc but they come barebones for the most part I just want a ready to go out of the box solution

Here's one I haven't encountered in many many many years. A brand new slim pc, and a Arkanis 12 port PoE switch. PoE switch is supporting a few cameras, another pc, server, etc. The situation: I plug the new slim pc into ANY vacant port on the PoE switch and it instantly shuts down half the ports, like watching the mgmt page of the switch as soon as the connection is plugged in ports 1-10 just blink to no connection Slim pc runs fine, just that those ports are now essentially disabled. As soon as I unplug the slim pc, all the ports blip back online and all is good. Tried all the different available ports, different cables etc etc... same thing every-time. IF I however plug in a cheap rear end trendnet 8 port switch first, then plug the PC into that... everything works hunky dory together. What in the world would be causing that problem? I looked at the Arkanis settings and there is nothing enabled that I can see, that would cause this problem Slim PC is set to DHCP, and I tried it with a static IP, same problem

Rexxed posted:Slim PC probably has some out of spec ethernet port that is messing with and/or shorting the PoE power on its ethernet line. PoE switches shouldn't send power unless the device asks for it (IIRC) but maybe that mini pc is causing some kind of havoc with it. I'd either get one of those PoE splitter devices or just leave a small switch hooked up to the mini pc, as stupid as that is (a 5 port switch is often be cheaper than a PoE splitter). Maybe if I try just telling it not to send power to that port under any circumstances? There are various options for disabling Power and making the ports plain old Ethernet only... never thought about it though I can try tomorrow, I just didn't think something so simple would completely kill a not-cheap switch like that

Stranger and stranger I turned off all poe features to a port and plugged it in there , same thing. As soon as the link is live ALL poe ports are shut down and the only active link is the one the slim pc is plugged into Tempted to contact the manufacturer and see if they have ever seen this before

Rexxed posted:That does seem weird as hell, almost definitely some kind of issue with their ethernet port that doesn't affect a dumb switch. I wonder if it's all of them or if you just got a faulty one. Maybe they soldered some of the pins together by accident but they're not normal data pins or something. I wish the pc had two data ports to try , I should check the bios and see if there is some strange setting enabled The switch itself is pretty new and functions 100% normally with everything else I have a usb Ethernet dongle I should try it just for shits and giggles on the pc

SlayVus posted:Weird thought, but is the switch a Gigabit switch? Are there other devices handshaking at a 100 Mbps connection and the on a Gigabit? Could you enforce 100 Mbps on all ports? It is gigabit. There are 2 or 3 devices connected at gigabit , And 4 more at 100 Of note I may have missed , all the 100 connections are cameras , which are pulling power. The other connections operating at gigabit are other pcs or direct links to other switches , which remain active while the camera ports are the ones that crap out Specifically , the units pulling power crap out , regular Ethernet seems to remain up

Fart.Bleed.Repeat. posted:If you apply external power supply(POE injector or wall plug) do the cameras continue working with just passing ethernet? Some of the cameras are a whole ball of poo poo to begin with. They're running on old 2 pair wire and fed into an nvt2 to bring them over to Ethernet. It's complicated. However at least one of the cameras is a brand new poe camera connected normally and it shuts down as well Yes all the ports are powered I mean it works as is with the pc into a small switch plugged in the main poe switch , I just hate daisy changing poo poo like that it looks sloppy and triggers me I'll futz around with it next week just for giggles because I like to know why things don't work like expected

So maybe my brain is tired but I can't really think of a good solution for this problem Situation - parents house has digital tv, comes in on a modem and is fed to the t.v. box via cat5. Router attached to modem which feeds the pc and wifi devices We are giving them a new tv and steam box for Christmas , and I want to hardwire the steam box to the network How would o accomplish this easily , as my only option in my head seems to be to run another cat5 across the room from the router , to the steam box behind the tv I tried to eliminate the 2nd router and use the modem/Router combo the isp provided , but it won't grab any dhcp for the pc when plugged in , So I'm assuming they lock it down to only work with the tv boxes for some reason Am I over thinking this , what am I missing ? I tried to get into the isp modem but the default password I found online doesn't work Bah

Ola posted:E-mail them and ask. Could be that there's something wrong with it, or it could be in bridge mode. (Also of course, reboot etc.) Also, the steam box probably works very well on WiFi, particularly across the room. Do you want to wire it for lag or download speeds? Perhaps do a test from a laptop. If you can max out the connection and get good ping, no problem. I'll check how it performs over wifi during Christmas , once everything is installed I almost always default to wired for stuff like that as I know wifi can introduce lag and jitters especially when you're doing streaming of games Even if I had to absolutely had to hard wire it in , it's really no other option than run another cable is there. I think I could do fancy things with the existing and vlans but that is way above the scope of work for my parents basement Blue On Blue fucked around with this message at 19:16 on Nov 27, 2017 |

fishmech posted:Why don't you want to just run the cable? It's the simplest solution, and especially within just the one room it's easy to run it in sn unobtrusive way, including tucking it behinf furniture and under carpet edges. Not my basement, we recently renovated the whole thing and the walls are nice pristine freshly painted etc... my mom would flip a turd if I poked another hole in the wall for a network jack I wondered about the powerline adapter as I use a set myself at home, would perform at least as good as a decent wifi setup I think

Stupid seemingly easy to fix windows 10 issue Was using my desktop the other day when windows comes up with a windows found errors on your drive, to fix it reboot I reboot and get a blue screen, now the pc will not boot at all. Just instant blue screen 0xc000000e I figured the ssd was failing, so I cloned it quickly to save the data Other pc could see the drive well enough. and it cloned no problems I pushed the cloned copy over to a brand new ssd. Plug it in and bam Same blue screen Did some googling and tried having windows repair , it wouldnt Tried chkdsk and such. No dice Tried some google results to fix the mbr and such kept getting errors about unable to access the drive Any help would be great

Geoj posted:Was this through installation media or the built-in startup repair? Well , I had our IT guy come and look. His solution was to wipe the drive and install windows Great, installed fine. I just finished setting most of my stuff up and did a restart to finalize some programs Now I'm getting reboot and select proper boot device This has to be related to eufi or whatever , I've tried all the bios options uefi on. Legacy mode on , drive is in ahci mode ( only other option is Intel optane) Its driving me insane the drive is there. Its visible in the bios. It simply refuses to use it as a boot device I reseated the ram. Check all cables And tried other SATA ports just now, swapping cables around between other devices that work :EDIT: I know one of the problems before the wipe was a partition issue, in that somehow the main partition was turned into some weird type I've never seen before (GPT?) And that made windows not want to load on it, so it had to be wiped. I wonder if it somehow keeps making itself a GPT parition and the BIOS doesn't know what to do with it??

Quick question , I'm looking to setup a video wall for work What is the goto solution these days , is it still matrox or something cards ? I'm pretty sure a high end nvidia card can run 3 or 4 devices, but how well does that work for making a video wall setup that is seamless?

Fragrag posted:What kind of media needs to be played on it? My work generally uses BrightSign players which seem to be like enterprise level Raspberry Pis which were designed to be media players. I’ve never messed around with them myself but they seem pretty reliable and stable for the sometimes absurd things we need to do. Not media so much as I just need a massive windows desktop Then I have a few surveillance camera windows I can place in any orientation I need Problem is the surveillance program is pretty GPU and CPU intensive , having 20 odd HD cameras live streaming is enough. Past that it starts to get slow And I eventually need to support probably closer to 50 cameras if not 60 So it's not so much how do I get 4 big screens together , but how do I support the program(s) I'm trying to display across them all at once

Sniep posted:just a quick question but have you ever considered approaching this horizontally instead of just beefing up a single box to infinity? Sorry not sure what you mean by horizontal .... is that virtualization ? I'm old school in my knowledge I only really know about running clients and servers and such How else should I be approaching this ? The setup is a surveillance desk. Where the person is viewing the feeds from a few locations, plus other programs they need on screen Right now I'm using one desktop to do email and also run the surveillance program, with two more computers running a monitor each for other tasks needed for the desk So I end up with basically 4 monitors , and 3 PC's I want to keep the desktop for the person to use for email and surfing. But a dedicated video wall that can run all the surveillance without having to require a user to login and out each time. Its just always up

Rexxed posted:I think he's just saying that if your one PC can't handle the extra load more cameras will put on the system, use more surveillance camera PCs instead of trying to cram it all into one. I would've called it parallel instead of horizontal but I think that's the gist. right that goes back to the question, how do I build a video wall, that can accept output from multiple streams so if i have two dedicated machines running the surveillance software, i would need to pipe both into the video wall or maybe I'm missing the forest for the trees here and there is a really good solution someone had thought of 10 years ago, but this is all new to me

Sniep posted:horizontal as in just multiple concurrent workers instead of one bigger worker, could it be split between a few pcs for a dozen cams a piece or something and then aggregated. yeah i'd be curious to see how they do it with the big monitoring stations our NVR is top notch, and they have software that will run ON a video wall to allow free placement of multiple surveillance windows etc, but i need to build and have the video wall running first  same idea but on a much smaller scale, how do?

FCKGW posted:What surveillance software are you using? everything is march networks, the NVR is headless and the client pulls up the feeds with the surveillance center software I AM streaming full HD full frame from all the cameras, but we are running a gig network so no problem with bandwidth. Maybe that's part of the problem, but I also don't want to sacrifice frame rate or quality if I can help it, as the cameras are critical, hence why someone is monitoring them 24/7

dreadmojo posted:speaking of startup, my keyboard input is incredibly slow (one character ever five seconds) after restarting for about a minute; I'm on an SSD, i5 and it's good and zippy all the rest of the time. I've tried some basic troubleshooting and done a bunch of searching, but haven't managed to identify anything. The processor isn't jammed up on restarts, so it's not that. Sounds like USB issues if anything, have you tried unplugging all other USB devices to isolate the keyboard? Or install the latest USB driver for the actual ports in windows

lllllllllllllllllll posted:Thanks Fame Douglas and Geemer. We have only one LAN cable downstairs that ideally needs to connect two devices (my PC and another device) online. But the second device only needs to be connected rarely, like, once a week if at all. So I thought an always-on network switch was a bit overkill and waste of power. Another solution is a LAN splitter, in that only one device is connected at a time, which would be fine, but it would also reduce bandwidth all the time. USB-WLAN also works as a workaround for me (not the other device) but I would naturally prefer the cable. Hm. Do you know how the cable is 'run' Is it secured inside the walls or just loose? There is always the possibility of pulling another cable through, either through fishing or using the existing cable as the pull-string
