Since I can't stop thinking about expanding my NAS (I've got a 2-bay NAS now, apparently my brain "needs" a 4+ bay NAS), so I'm looking into building one from parts vs just buying the 4-bay Synology.
Finding small cases with four drive bays is apparently hard; they've all got 1-2 bays and a huge amount of space for a massive GPU because only gamers buy them?
Is there already a conspiracy theory as to why #printers always fail completely when you want to #print the most urgent and important documents? If not, let's invent one! 😈
The good folk at WAVLINK have sent me their Dual-Screen USB-C adapter to review. Plug it in to a USB-C socket and you now have two extra monitor ports. It'll even work on a USB-A socket, if it is USB 3.0.
The USB cable has a dongle which converts it from C to A. That's handy if you don't have enough C ports. But the cable being so short means it is sort of awkward to place. If you're on a narrow desk, the weighty adapter will just be left swinging.
On the back are four ports - two DisplayPorts and two HDMI.
But you can only use two at a time. I stuck a DP in the left and an HDMI in the right and (eventually) it worked! I was able to get 4k @ 60Hz and 1080p @ 60Hz on my screens.
It also passed through audio, although I couldn't find a way to select which monitor received the output.
There's also the requisite blue LED to let you know it is working.
Sadly, it is a bit of a faff to get set up because it is a DisplayLink adapter, rather than a USB-C hub. The manual spends 11 pages talking about driver installation!
Plugging it in to Linux shows 17e9:6000 DisplayLink USB3.0 5K Graphic Adapter - so it was detected without issue. That said, there were some warnings in dmesg:
Warning! Unlikely big volume range (=672), cval->res is probably wrong.[7] FU [USB Audio Playback Volume] ch = 6, val = -10752/0/16
But plugging it in doesn't give you extra screens. Instead, you need to visit DisplayLink.com to download the drivers. They are only available for Ubuntu Linux. There are also drivers for Windows, ChromeOS, Mac, and Android.
Despite my best efforts, I couldn't get them to work. It looks pretty buggy. Instead, I downloaded a random GitHub repo which installed the right drivers and got it working.
Once that was done, my laptop happily detected both external screens - one HDMI, one DisplayPort. It was able to change resolution, rotation, and refresh rate using Wayland. It even worked through the USB-A socket as well as the C.
It's hard to know who this adapter is for. On the one hand, it does its job brilliantly. It turns your USB3 / USB-C port into a dual output device for two 4k monitors. On the other hand, that's all it does.
Installing the DisplayLink software is a pain. USB-C means that I should be able to plug in an adapter and have it just work. With this, you have to manually install drivers and reboot before it will work. Good luck getting those drivers installed on a corporate laptop!
In theory, it can go up to 5K (5120x1440) on each DisplayPort - but I don't had a screen to test it on. If you need that sort of resolution, that's the only reason I can think for buying this.
It works - but it isn't plug-and-play, the drivers are a pain, USB cable is too short, it has limited functionality, it is too bulky, and is over-priced.
@baldur I'm sure the big tech companies make sure to value the AI #hardware close to the original purchase price in their yearly financial reports, even after running 365 days @ 24/7 😂
CPU's / Graphic Chips probably survive the servers a maximum 3-10 years under these conditions right?
Can anyone have any idea about what this #mysterious#IBM#hardware can be ? I can't remember precisely how I got it, I THINK it was from a dumpster or found in a pile of some "electronic garbage". I have absolutely NO IDEA what this can be , I have a SUSPECT but I could be totally wrong, I THINK they MAY be part of an IBM 5100 but I can't be sure, if anyone knows what they could be I'd be interested to know !
Long-shot to end all long-shots but: does anybody know anything about USB on raw Xilinx transceivers (e.g. without a PHY)? Officially it's unsupported, occasionally people say they've gotten it to work and more details on exactly how would be incredibly useful
People like to say how it's so expensive to make video games today.
What makes it expensive?
Is it the high end hardware.
is it the fact that game devs like to make games 100gb+?
is it because voice actors want more money?
whatever it is, is it possible to get a good modern game that's atleast under 50 gb, that takes advantage of all the modern visual effects and graphic capabilities but not be so demanding and expensive making them?
It's funny because the newest call of duty is so big it had to be split up.
150 gb+ install size
So, I was diagnosing a weird webcam issue for days and days. I've been using a Oculus Rift Sensor for head tracking for a while now and it suddenly stopped working. It's basically just a USB webcam. I tried several different kernel versions and even some from last year with no luck. I dug into the code of the uvcvideo driver, I tried setting quirks, nothing helped. I was obsessed with this issue.
Long story short: I disconnected my computer's front panel and everything worked.
The front panel must be faulty which must've tripped the USB controller in such a particular way that it kept working fine but was unable to recognise newly plugged devices and sent garbage to the kernel.
What the actual heck. USB is so weird. Do you have any USB stories like this?
In former times, not only professionals became real hardware nerds. As you could never know what part you'll need for the next repair of your devices, you better collected every part that you were able to spare. Above all, you could never have enough keys to restart the device. In organised households, these were attached directly to a key board.
Mam sprawę do ludzi zajmujących się sprzętem, ewentualnie do jakiś adminów.
Jakie są szanse, że dysk SSD(M.2)/SSD(SATA) będzie w stanie poprawnie działać na lapku, kóry teoretycznie nie obsługuje takiej wielkości dysków? Obecnie mam SSD(M.2) 1TB, ale muszę kupić coś dużo większego i pomyślałem o SSD 4TB. Wszystko pięknie, ale wg ulotki producenta (z okolic 2018/2019), ten laptop jest w stanie uciągnąć max 2TB. Zarówno na złączu M.2, jak i SATA.
Dzwoniłem do pomocy technicznej producenta, ale trafiłem na gościa, który brzmiał jakby wczoraj za bardzo zabalował i jeszcze kac go trzymał, a co za tym idzie, jedyne co się dowiedziałem, to żeby patrzeć na to, co jest napisane w ulotce.
