content: Hey,I dug out an old PROBOX2 EX Plus. When I plug in the power, it shows the PROBOX logo screen and then keeps restarting itself.I assume the memory might be corrupted and needs to be reflashed, but unfortunately the PROBOX website is down and every link I found to firmware images and burning tools is broken.If anyone has working links to the IMG file and the burning software, I’d really appreciate it.Also, I’m not 100% sure this is just a firmware issue. When I connect the OTG port to my computer and pulling the reset botton on powerup, Windows keeps detecting new hardware and then disconnecting it every few seconds. Does anyone happen to have the circuit/schematics for this box?Thanks!

Dash to panel gone rogue gnome 46 ubuntu 24.04 wayland - Page 1

content: So, until last night i had been using my pc with ubuntu 24.04.3, with gnome 46 and with dash-to-panel@jderose9.github.com to have a taskbar-looking panel at the bottom of both of my monitors, and i was using the intellihide setting to make that auto-hide, basically like how windows hides the taskbar and you hover at the bottom and it shows up.Anyway, until last night everything was working fine. full screen games were working ok, panel wasn't showing up at all in full screen, just like i wanted, and expected it to work. I turned off my computer last night, and when i turned it on today, it started working ok, but after a couple of minutes of being in game, panel started showing up in game, and i lost controls for the game. nothing worked. i rebooted, it worked ok in game for like 20 seconds, i managed to move my character a little bit, then panel showed up again and i lost controls again. further reboots didn't work. all settings in dash to panel are the same as they were when i set it up. last time i ran sudo apt update/upgrade was 2 days ago, then a few minutes ago hoping something in the update would fix it as inexplicably as it had broken.I asked the various chatbots for help, nothing they suggested has helped.Anyone here got any suggestions?Thank you!

content: Interesting project, but rather than rendering Wayland into a terminal, a bigger impact could come from addressing one of Wayland’s long-standing gaps: reliable control over window geometry. Unlike X11, clients cannot set their own position or exact size, which makes it hard to restore layouts, script window management, or integrate with tiling workflows. Solving that would probably benefit far more users and remove a lot of headaches when developing for Wayland.

Not clear whether you're supposed to drag the selected stuff from one window to the other, use Ctrl-C to copy and Ctrl-V to paste, or something else.I'm using an old version (4.11w), can't upgrade using the built-in update facility (probably wrong URL or something).I wouldn't mind getting a newer version, but I'd really like just to be able to copy stuff for now (the software works fine for me otherwise).Can someone give me a step-by-step process, like I'm a total n00b?Would appreciate that.

content: After selecting 'Duplicate' and selecting the component or region to duplicate, you can change child windows *once*, e.g. by opening a new schematic window, or using the window menu or tab bar or just click in the new window without loosing the copied part(s) 'hanging' off the cursor, so can simply click to place as usual. Note that duplicate doesn't work while editing symbols.

I've had Android phones that work perfectly fine without a battery connected, but Apple iPhones refuse to even boot if the battery is disconnected or faulty. I have an old Motorola phone which works without the battery.When I worked in Digital Forensics, whenever we had an iPhone that had a dead battery, we would rip the mainboard out of the phone and connect it to a test fixture board with external power, and connect up a spare LCD to it.

Notebooks with compartments for USB devices? - Page 1

content: I wonder if such a thing ever existed or can be found nowadays? I am talking about compartment on the bottom side of the notebook where you can place devices like USB flash drives, wifi dongles, etc. and then close it with a plastic lid or something like that. It's like an USB hub in a box with some free space. Recently I've booted into my decade-old Toshiba notebook and was fascinated by the comfortable feeling of thick enclosure, keyboard and screen with solid plastic borders. It has pretty large and emoty HDD compartment, because the SSD was is installed instead of CDROM using upgrade adapter. It can easily fit large USBC SSD drives, some USB dongles, and with some careful arrangements I thing even a small dev board. During pandemic I've upgraded my Dell laptop using this idea: because pcie extension pinout had USB2.0 port pins available, I've soldered it to the newer USB wifi dongle which provided much better wifi connection and reliable bluetooth connection for Mouse and Headphones. Considering the microscopic size of modern laptop motherboard (mine is comparable to a smartphone), it would be so easy to implement such compartment, but it seems that there is no demand for a such function.

I bent the SSD's PCB while installing it in a no-name laptop. - Page 1

content: I have one of these N5095 laptops and few months ago during swapping of SSD drives between laptops I've discovered that my 512gb SSD's PCB was bent. The reason is that internal screw forced the PCB down too far. It worked reliably, thanks to the fact that the PCB has a lot of space left for unpopulated memory chips, and only two large chips ​​were​​ near the screw hole. If the chips had been closer to the middle of the board, with some 1TB drive, I think it ​​would have been​​ damaged. When I removed the drive, the board was still visibly bent because it was there for a long time. I've added an EVA foam adhesive strip below the screw hole to relieve the pressure. Interestingly, on a very similar laptop with minor enclosure differences there was no such issue.EDIT: I've also used another type of the screw with tapered head, which extended the margin a little bit further. Be careful when installing SSDs into notebooks like mine. Btw, looking at my today's photo, it seems that SSD still kind of "deeper" into enclosure on the right side near the screw.

iPhone Text Message Software Company Warning - Page 1

content: Some years back I used iExplorer by Macroplant to transfer my iPhone text messages to PDF. I was somewhat pleased with the software as it did exactly what I wanted.Recently I purchased their latest version (v14 I believe) to perform the same tasks. Upon using it, I noticed it didn't detect initial text messages that were started in a thread. Initially I thought maybe it was due to length of the thread and it was getting truncated, or that they were combined from an old iPhone when I purchased my new version phone, so the format was different.I looked at one thread that I started just a few weeks ago with someone (not more than maybe fifty text messages), who also has an iPhone, and it too was missing the beginning text messages we exchanged; also, all of the photos exchanged were showing as just blank squares. Seeing how the first few (or several) text messages were missing, I lost faith in all the text messages transferring correctly.The company offers a 30-day, 100% refund, however, as of today (1/9) they didn't respond to the three emails I sent, they don't list a phone number, and, unfortunately I paid with a debit card, so my bank isn't able to go after them.While this is poor business practices, I wanted to send a warning to anyone who may be interested in transferring their iPhone stuff so they don't get ripped off as well by purchasing their software.Thankfully it was only $39.99 I lost, but, it's obviously the principle along with them being able to continue making an income from other customer purchases without supporting their software or honoring their guarantee.

One problem with DLLs is that they are built with all code included as the compiler cannot know at compile time if something will be used or not. Dynamic linking here is not appropriate as the DLLs are only used by exactly one process and there isn't any kind of need to update one specific library independently.My guess is a combination of dynamic linking to comply with Qt's LGPL -- to avoid having to pay for it, and lack of really caring.By why is nlog.dll in here? This is clearly a Qt application and nlog is a .Net DLL. Very strange!

(Not sure, if they later abandoned this sticker, as it certainly adds to manufacturing costs...)After all, it's simple: buy a branded cable that states the certification. Don't trust any AliExpress/ebay/Wish/Temo specifications.A proper test would require a multi-10k setup to generate eye diagrams. I think Linus Tech Tips showed one system a while ago...

I've performed several basic measurements and would like to share the results.The board enters a "ready to power on" state after plugging in the PSU.Pressing the power button increases power draw.Sometimes, touching the RSMRST_L pad with a multimeter probe causes the board to shut off and return to standby.Measurements:(taken after pressing the power button, while the board is attempting to start)H_SKTOOC# = 0VO_RSMRST# = 0V (but 1.8V while in standby)O_SLP_S3#_R = 3.3VO_IOPWRBTN# = 3.3VO_KBRST = 3.3VPSON# = 0VS_RTCCLK = 3.3V, 500–600 kHz square waveLPCCLK1 = 3.3V, no waveformLPCCLK0 = 3.3V, no waveformLFRAME = 3.3V, no waveformPCIE_RST_L = 0VVDDQ, VTT, VDDP = not presentStandby (before pressing power button, including the ATX PSU emulator module): ~120 mAAfter pressing the power button: ~760 mA (including the ATX PSU emulator module)There is no visible activity on the LPC or SPI buses.The board does not proceed to full startup.Do you have any ideas what else I could check, or what might be damaged?

content: No, the board has no visible physical damage.I have a similar issue with another ASUS board that uses the same NCT chip (NCT6798D-R), but that one stopped working suddenly from one day to the next. It was my personal board.I checked the AM4 socket using a socket tester — everything looks fine.I'm using a power module that emulates an ATX PSU, but I’ve also tested with a real ATX power supply — same result.I also tried the USB BIOS Flashback feature, but it didn’t help.I haven’t noticed anything unusual with the voltage rails — most are within 10%, though some are slightly on the high side.For testing, I’m using an AMD Athlon 200GE.Unfortunately, I don’t have a POST/debug card or RAM tester available.I forgot to mention: fans and RGB LEDs do turn on when powering the board.However, the onboard debug LEDs don’t show anything — no signals, no activity at all.

content: Welcome to horrible crosstalk resulting in poor display quality. R, G and B each really need their own individually screened 75 ohm impedance controlled coax cable if going more than a few inches. Also if you are really unlucky, the graphics card may interpret the lack of EDID as being connected to a very old VGA monitor, and may not allow 1024x768 or the scan rates you want. Usually this isn't a problem on any graphics card that allows you to cleanly override the EDID mode list.

I would be either interested in the PCB files or an existing interface card. This would be interesting for me, as I started at about 1988 to do data acquisition with the Apple ][ and I'd like to continue from that point ...Guido

That is, it presents some interface on the LAN (can be with a browser or a dedicated app) to allow the user to change the video output mode from another computer on the network. It should support the standard VGA and HDMI resolutions at a minimum, even better if it can allow custom output settings only limited by the GPU hardware capabilities. There should also be a selection of test images and patterns that the user can pick, with the capability to upload/stream a custom image or video a nice bonus.Main use is testing/"fuzzing" video related devices, such as capture cards and scalers.

I have enough memory left and all batteries are full.I thought, I could measure at least several hours with the advantage of seeing the graph directly on my phone while sitting a few meters away at my desk? 10:36:14 minutes was the maximal logging time, which makes the use of the "IR3000 FC Connector" not really useful...comparing to the 24 hrs with 1 sec sample interval with the Fluke 289 itself?Thanx & best wishes!

Are there any recommended enclosures for this? I plan to keep the old one in the enclosure, once I get the new SSD swapped into my laptop, but I will mostly keep that original SSD as a backup and don't intend to use it as an external drive (so I don't need the "best" enclosure or worry about long term cooling issues).Any help's appreciated.Thank you.

content: If you ever need to update the firmware on the drive, do note that not all USB to NVMe controllers support that. The only reliable way to use an NVMe drive externally is to get a controller that supports "PCIe tunneling". And that requires a Thunderbolt 3, 4, or 5 controller. In theory, a USB4 controller should work, but the USB-IF and their brain damaged spec say that PCIe tunneling is optional. So a random USB4 enclosure may or may not actually support PCIe tunneling...I buy Thunderbolt enclosures to avoid the above problems that crop up with USB enclosures. In addition to updating FW, non PCIe tunneling devices may or may not work with TRIM (most Taiwanese controllers (I'm looking at you ASMedia) have poor support for TRIM) and ASPM (power management) may not work.Now, if you are just backing up files from a laptop drive or testing drives, really any enclosure/controller would do okay. But if you want high performance and want FW updates and TRIM to work without a hitch, Thunderbolt is really the only solution. Or--if you can find one--a USB4 controller with PCIe tunneling.

content: Vaire is a startup that seems to be trying to tackle an idea known about since soon after Landauer's principle was published in the 1960s. That if you could compute reversibly, your theoretical minimum amount of energy to compute could tend to zero, rather than tend to the Landauer limit. The Landauer limit is the theoretical energy inherent in flipping a bit, as opposed to the massive real world energy we currently take to flip bits, because we lose so much to leakage and resistance. I've heard the name Vaire a few times over the last 3 or 4 years, but I just saw something that says they aim to have something working this year. Does anyone know more about them? All I can find is really vague. Unless they are doing something at superconducting temperatures, I can't see how anything major can be saved over current solutions, but I don't see superconducting mentioned in the stuff I have seen. There have been some university demonstrations of Landauer erasure in superconductors.
