content: Hi all,I'm thinking of using NB-IoT for a project in the UK. I won't have any control over where the finished units get installed, so I'm hoping for reasonable, national coverage and I've been looking online to try to find out if I can expect that. All I've been able to find out so-far is that Vodafone seems to be the only operator providing it and they don't seem to publish any coverage info. O2 seem to have gone the LTE-M route and theyhavepublished a detailed coverage map. At the moment, I can only assume that Voda's NB-IoT map wouldn't compare well with that, or they'd publish it. I'd love to have some real info though.I've tried contacting Vodafone but, in the meantime, does anyone have any experience of NB-IoT in the UK? What sort of coverage are you getting?Cheers,Colin.

content: Voda NB-IOT is behind a firewall and can only forward packets to a specified IP address they whitelist, so if you use a cloud service by URL as your service IP may change as you shut down and spin up a new resource, it doesn't work.NB-IOT is, or was when we trialed it last year, single homed, so no roaming if your vendor has a network problem or the cell site is down for maintenance and you can't pick up another due to coverage.Even though we had a trail with micro sims and embedded sims for devices we made for the trial, they weren't really that responsive. Voda appeared to want to compete by making devices and offering the full service.

content: ...and neither do USB HID's by the looks of it?Thought this was more of a software issue than repair so i'll post it here.Basically i bought a laptop (Lenovo G50-30, model name: 80G0) that was destined for the recycling bin because keyboard and mouse don't work on windows, i can't even install the windows OS. It does go into the install process if i boot from the USB flash drive but i can't click or select anything.The guy who sold the laptop had installed Ubuntu on it and everything works fine. I've never come across an issue like this, is this a problem with the BIOS or does it just need a good reset?Ps: if i enter BIOS keyboard works fine.

Seen it a couple of times.Failing that, stick an external USB keyboard in it, install windows then update the BIOS from Lenovo's web site. That'll reset it.There's also an SMC on there which sometimes goes wonky on some Lenovo machines. You need to physically disconnect the battery to reset it on the consumer models (there is a little button that does it on the Thinkpad line)

Fan header that Nvidia is using on video cards? - Page 1
Forum section: electronics / general

timestamp: September 22, 2020, 01:59:07 pm
content: Hi there,Please see pictures down below. I've the Quadro FX570 for CAD applications. But I was annoyed by the loud noise from the original small cooling fan. So I installed a big copper heatsink onto it.That was some time ago, and I used the computer since without any issues.Recently when installing another expansion card next to it the temperature got to 75 degrees C. So I decided I wanted to add some air flow over it. Anyway I don't what to engage in discussions whether 75 C is too much or not. Just accept I installed a fan to it like you see in the picture.Currently the fan is driven by a motherboard fan header. But I would like to use the fan header on the videocard for it, because that one increases fan speed (PWM) based on the GPU temperature that is measured.The video card uses some other style fan header. See that other picture.My objective is to:1) Find the crimp terminals that Nvidia used on the original fan plug.2) Cut of the fan plug of the Noctua fan.3) Crimp the Nvidia style crimp terminals on the 4 wire ends.4) Install the 4 crimp terminals into the plug housing from the Nvidia fan.I've checked some electrical specs to see if those are compatible and that looks fine.I was looking around on Digikey to visually compare plug housings with what I have in my hands. I believe it is from TE HPI 2.0MM RECEPTACLE HOUSINGS. Very likely the TE 440129-4. I opened the datasheet and compared key dimensions with the one here. They match. Now the PCB pin header should then be TE 440054-4.If someone can confirm the above is correct I would have no trouble to find the compatible crimp terminals. And I think crimping would be a success with my Engineer PA-09 because I can select the crimp die slot separately for the contact wires and the insulation.

One ATX PSU to power supply two motherboards:: is it possible? - Page 1

timestamp: August 31, 2020, 06:32:43 pm
content: I am thinking about building a computer with two motherboards in one small cabinet; each motherboard needs neither hard-drive nor GPU, just need a lot of ram (>=4Gbyte) for the ram-disk and a fast LAN (>=1Gbs) to bootstrap from the network.Peripherals are not a problem, motherboards are in m-ATX form factor, both equipped with Intel Core2 Quad Q9650 chip @ 2.9Ghz, and each board doesn't eat more than 150 Watt.I can build the special cabinet myself, just .. what about the PSU sub section? Can I use one single big 500 Watt main power supply to feed both motherboards?In case, if it's possible, is there any kit/cable/something to do so?Thanks

content: Interesting question.I'm not aware of this having been done and I doubt there are kits. You will probably need to DIY an ATX connector splitter.Turning on one board will apply power also to the other. I'm almost 100% sure that it won't cause it to actually start running, what the exact effects will be I don't know. It ought to be harmless, I think.editA less unorthodox solution is to use some beefy 12V-only supply (possibly even ATX) and a pico-PSU for each board.

content: Atx 24pin splitter (Y) cables appear readily available (don't forget you might also need to split the smaller cpu, gfx power connectors etc if your psu doesn't have enough of those). I think you would want to lift and hard wire ps_on to ground to force the supply to be always on, otherwise it would depend on how each motherboard implemented the ps_on signalling (in regards to if it pulls up/down hard or with some resistance or leaves the off state as open circuit)

content: Hello,As a non experienced linux user, basically only normal routine maintenance (log analysing with lots of google search for understanding and copy of commands on a text pad and written on a book for memory) and currently 99% of all my computer use is on Fedora (forcing myself to not use Windows), I come across the Fedora Silverblue and their container based workflows. From what I read it's based in the LDK (Linux, Docker, Kubernetes) stack, but from that I simply got more confused than before.Also I've been seeing a lot of use of Docker specially in Youtube videos and in reddit r/homelab, where people show their home labs and migrations into a Docker platform and talk wonders about how easy it is and good it is. But I simply can't understand what is that. It is like you have Linux, and then all and every app have their own container that doesn't interfere with the system below? But isn't what normal Linux currently does too, or all OS were the Apps have their own sys files and registry entries that are only them and not affect (mostly of the time) the OS? Or I'm basically totally wrong and should shut up and just forget Linux since it is not for me?Can please some of the users of Linux here with ton more experience than me and explain me as the yellow books (For Dummies) or steer me into some resource that is easy digested and understandable but at the same time allow for experience and tentative and error?Also how that could be used into the real world in a situation as an end user as me (if it can be used like that or simply is only for a certain type of user base).

Down the East of the country O2 are rolling out Cat-1 LTE; also useless in a product. A few countries have had NB-IOT for a lot longer but you won't get good coverage everywhere and they also need different SIM cards to regular cellular services. I.E. you might have a Vodafone mobile phone SIM but this won't work with your NB-IOT modem even if you're by the Vodafone NB-IOT tower. You need to ask Vodafone for a NB-IOT SIM.It will be a few years before these become a viable product so for now we're just selling 2G stuff still. 3G is gone already!

I mapped CAPS also as CTRL in Ubuntu Settings, and CAPS still functions as CTRL. R-CTRL functions normally as well. Both user session and gdm login from suspend/lock screen are affected. DOES NOT AFFECT SYSTEM BEFORE FIRST VM IS STARTED. Few minutes after VM is shut down, VMWare will release the key to OS.Attempts: tried to turn off hot keys in VMWare, no help. Tried to map hot key to shift and alt, no help, plus even after mapping shift and alt as hotkey, shift and alt still work in host OS, just don't press them together. So it seems not to be a hot key issue.Problem: apparently, no ctrl+a/z/yc/v really ruins your day, and while CAPS is confy for most cases (that's why I mapped it in the first place), for certain keys L-CTRL is still more comfortable, notably ctrl+z.Any ideas why it happens, and how to deal with it other than retain my typing preference?

Chen.and obviously took it apart (since I don't really want a gadget of unknown provenance on my network)...I am quite intrigued as to how it works...There is a PIR sensor and a SGM8139YS16 which is a PIR AFE)... there is also a 8L051F3P6 which I think is a STM8L051F3 i.e. a reasonable 8bit uP with 8k flash etc... and finally there is a TYWE35S which is an ESP8266 (32bits and 1M byte flash etc).The TYWE35S clearly has RX/TX connections so I snopped those and got...Would the protocol between the TYWE35S and the STM8L051F3 be a standard of some kind or is this likely to be totally proprietary?Could that be the TUYA protocol?PSIt's a DP-WP001 v1.3

In IXTU the option to undervolt is disabled(no possibility to undervolt) so i can not undervolt my CPU. Do i have to enable something, to have the possibility to undervolt my CPU, or is it that Intel doesn't allow these CPU's to be undervolted.Throttlestop also doesn't work on my laptop. Is there another free program so i can undervolt my CPU
DDR memory bit width questions - Page 1

content: Hi guys.According tohttps://en.wikipedia.org/wiki/Memory_bandwidth#Bandwidth_computation_and_nomenclature, “Each DDR, DDR2, or DDR3 memory interface is 64 bits wide.” But inhttps://en.wikipedia.org/wiki/List_of_Qualcomm_Snapdragon_systems-on-chip, those processors are using all kinds of different bus width per channel, such as 32 or 16 bits.Q1. Why and how they don’t use the standard bus bit width? I recall all x86 system should have 64 bit per channel, are ARM systems just different?Q2. What’s the difference between two system with same total bit width, but different channel count(such as 4 channels x 16 bit each VS single channel 64 bit)?Thanks.

content: Just Wikipedia being full of it as usual. Most of it is written by children who just learned something new and need to share it with the worldRAM modules made for x86 systems are always 64 bit wide because that's what the x86 needs.RAM chips are available in bit widths like 8 or 16 and it takes a few side by side to assemble a module that x86 would be happy with.Other CPUs may use other widths. If you take apart some embedded system (router, digital camera, ...) it's not unusual to see a SoC being happy with just one RAM chip.Q2: the channels are independent and can be doing different things at the same time.

content: To elaborate on Q2, it's a difference in how you wire the control pins and how the RAM controller works.Multiple chips making up a wider module: all chips receive the same commands, the data bus is split between them.Multiple chips on multiple channels: each channel receives its own commands separately and has its own data bus independently scheduled by the controller.Total bus width and peak throughput adds up to the same number in either case.See also: ganged vs unganged dual channel mode on x86.

content: They're the junk a Windows install accumulates over it's lifetime. Often these are update files and restore points. Be carefull deleting them manually as Windows Update may get out of step and kill your machine's response by trying to do a retrospective update. The only issue is these files get fragmented all over the disk map and refuse to 'defrag' because they're protected system files.Try running theWindows Disc Cleanup Tool(built-in) which should offer a 'Windows update cleanup' option.

content: Quote from: Lindley on June 02, 2020, 03:55:49 pmThere are other vendors of similar snake oil suites, but the real question is why one would pay money for software which, across all vendors, has a very long track record in missing most malware attacks while at the same time actuallyincreasingthe vulnerability of your own system (providing more attack surface, aside from occasionally self-sabotaging the PC it runs on by mis-identifying some critical OS files as malware)? Or in some cases even selling their customers' web browsing data (like Avast did)?All these "security suites" are scams, it's as simple as that. You'd get roughly the same "protection" by spraying Holy Water on your PC.If you run Windows 8.1 or 10 then there is no need to pay for antivirus software as the Defender software which comes with Windows already performs as good or often better than the majority of paid-for antivirus software. As long as you keep your system and software up to date, use a good ad blocker (not just because ads are annoying but because ad networks are one of the major, if not the major attack vector for malware) and use a bit of common sense (i.e. not clicking on that link in the email which notified you of a big win in a lottery you never took part in) then you're as safe as reasonably possible for an individual.
