content: I guess this shouldn't be a secret, but upon googling there's no related topics?Basically, use a clean browser without existing cookies, search some military related things on ebay, eg. "night vision".If your IP is in US, you get 6-digits number of results, otherwise, 4-digits.For years it was easy like that, use a proxy or VPN and you are all set.But recently, not only the IP rules are getting stranger(there are more tires, some IPs even get too few results to be useful; and some IPs in US also not working), but also, it seems they show different results range based on OS/browser.This really annoys me, currently, I have the following results, all from US IP, clean of personal cookie/data, ebay.com main site, desktop UA:IOS+safari: full results,Android+Firefox: partial results,Windows 10+Firefox: partial results.I haven't tried to spoof user-agent yet.Anyone have similar problem? What's your condition and results?I guess ebay is just abusing it's dominant power.

content: Querying from Poland I get 120k results on ebay.com.Be aware, however, that not all sellers ship worldwide. So you may have your location set to a place which is less popular or that type of equipment can’t even be send from some countries. For example I get only 92k results if I want to ship to Afghanistan. If you haven’t provided the information, eBay does some guessing and that may fail.If you are using a VPN, you may be considered a scraper bot and then you are provided with intentionally distorted results.“Abusing dominant power” to decrease their own revenue is not a plausible explanation. It’s in their interest to make you buy the item, not to prevent you from doing so.

content: Indeed...it's the same reason why I almost don't use ebay anymore...I say almost, cause I still buy vacuum tubes and cold war era new old stock stuff.It's even worse if you're in India...Nothing Chinese even show up in any search result anymore after ebay.in got shut down (and ebay.com went shit)I think they don't want your money anymoreBut it's really sad...My average spending on ebay was about 50$ per month. Onlt good thing about it is, Ukeranian and Russian stuff is still available if I use .co.uk or .ca instead of .comI just want an explanation of why they are doing this, if a solution is absent.Another tip... opera has "VPN" which is actually just a proxy but it can allow you to see results of .com site as if you were on a different continent

Best single board for a lock. - Page 1

content: We have been using a FOB lock in a commercial setting, about 100 daily visitors, each has his own FOB key. In the same box with the lock controller is our own mini computer that runs windows and acts as an intelligent bridge between the controller and the main server that is located offsite. Now obviously this is too complex and expensive. We could retire the door controller and drive the locks directly from a single board computer that also would connect to he main server through https. The question is what board to use. It is not a medical or airplane device but still needs to be reasonably reliable. More than one failure a year unacceptable. Would a compute module raspberry pi do ? If not what would ? Currently the bridge is a dotnet core application, so the board has to support linux.

content: From a reliability stand point, I don't see an issue with the Raspberry Pi - I ran a Raspberry Pi (3b) based ADS-B receiver for a number of years with the Pi mounted in a sealed enclosure and the only problem I experienced was a damaged PoE splitter caused by water leaking into the ethernet cable. The splitter was not a part of the Pi and the Pi itself sustained no damage, I just lost the ability to communicate with it.The Pi runs a debian linux based OS, so that aspect of the requirement is met, although I suspect you might need to recompile the app for it to run on anarbarm based processor.You say you want to retire the lock controller and drive the locks directly from the SBC - I have the following questions ...1 - how do you plan to drive the actual lock mechanism from the SBC? Most SBCs have limited current sink/source capabilities and will need some sort of an interface card.2 - how do you plan on interfacing the FOB to the SBC? There are different types of FOBs and a reader of some sort is going to be required, which will also need to interface with the SBC.I can see you replacing the mini computer you're using as a bridge now with an SBC but replacing the lock controller itself will present a few more challenges.

I would suspect something like directX, QuickTime, or something like that. QuickTime is Apple stuff, so between directX and quicktime, try installing quicktime and then reinstall iTune again if needed.Also, if you could find older versions, get iTune of the Xp-Sp3 era instead of much later iTune that says it support Xp.

Question about torrent and MITM attack - Page 1

content: Hi guys, I want to ask a question.If a user have a legit initial seed (magnet link or .torrent file), but the downloading happens in a very dangerous network(Let's assume the worst case, the hacker have ISP-level control over the network), he can just fake every node, so encryption to peers is useless, and there's no way to cross-check.Will the user download the tempered files without notice?Here's my guess: Since the .torrent file (or the magnet link finished "download metadata") contains hash for each file, the hacker will not success. But if the user only have magnet link, and the metadata is downloaded on a dangerous network, I don't know if the hacker can fool the torrent client. (I know the magnet link itself contains a hash for the whole torrent, but I don't know if it will be enough)Does anyone know? Thank you everyone.

If I wasn't slammed I'd try working on it / writing some code to emulate BIOS and play around. However it isn't as trivial as "load BIOS blob and run it" - I mean it almost could be for some tasks but for enough compatibility it would take some work.

content: Unless there is some sort of trick with using the bootloader from another UEFI compliant OS I doubt this will be easy to do without invoking the CSM. You may also run into issues if the HDD/SSD is formatted as GPT (GUID partition table) rather than MBR (master boot record).If you specified what OS are you are trying to boot into you will likely get better help than a generic question.Personally, I would just use a virtual machine to run the legacy OS inside a UEFI compliant OS. If you have thunderbolt and a thunderbolt video card (say from a dock) you can have native full speed graphics support inside the virtual machine. Though it is quite complicated to get working.On a side note, I remember that Windows 7 was unable to run on my Surface Pro 3 due to it not supporting the newer UEFI standards that dealt with the video bios during booting. I can't remember what exactly would be required to make it work, but it was certainly beyond me at the time and no ready made solutions existed. If you are attempting something similar, you may as well give up and use Linux or Windows 8.1/10/11.

Great quality keys, ports and overall finish.I am also a big fan of Dell business lines, but my last three year run with the Latitude E5510 left me with a bad taste and with the impression the quality is dwindling. The laptop had great specs, but the battery swollen after just 1-1/2 years of use (out of warranty already), which almost took out the touchpad. The replacement was expensive (although on company dime) and I have 7~8 year old Dells (Latitude E6520) with batteries still in great health.

It works and it perfectly undeletes every file which has not been overwritten yet (either data or metadata).Given my vague recollection of how FAT32 works, I'm not entirely sure if the same is even possible there at all.There are "file carving" programs like photorec which simply scan the whole disk sector by sector and look for something that resembles a JPG file, MP3, DOC or anything. You can forget about recovering the original file name, location in the directory tree, etc.

content: I have an HP Envy All-In-One and it has two display adapters. There is an Intel 630 and an NVIDIA GTX 950M. On the back, it has HDMI In and HDMI Out with a little pushbutton to select between internal and external signals to the screen. Other than that, it's just an ordinary 27" touch screen display.Like this but older:https://www.hp.com/us-en/shop/pdp/hp-envy-all-in-one-27-b235t?cq_cmp=12690829826The question I have is which video adapter is driving the screen? It only comes up because I started playing with the NVIDIA CUDA cores and this clearly works. I was expecting the display to blank during the execution of CUDA kernels but I haven't seen it so far. Of course, the cores are pretty fast and there's a bunch of them. In this case bunch = 640.I have attached a copy of the Display system information.

Anyone Use Avrdudess and/or Arduino IDE 1.8.13 - Page 1

content: I came across a website that gives a good (and simple) tutorial on updating the firmware on my Anet A8 3D printer (https://01001000.xyz/2020-08-06-Updating-Firmware-Anet-A8-Board-1.7/).With the exception of projects at work, I've never updated firmware for personal stuff; or worked with an Arduino. My question is whether anyone has experience with the Avrdudess that can confirm it's not dangerous software that installs a virus.As for the Arduino IDE, I'm assuming this is a legit program, but wanted to know the same and whether it's safe to use.Any input will be appreciated.

content: avrdudess simply builds the command line arguments to pass to avrdude.In the case of updating the Anet firmware, that page only uses avrdude to backup the existing firmware, and it gives you the command line arguments you should use:Code:avrdude -c usbasp -p m1284p -U flash:r:aneta8-flash.bin:rTo upload the new firmware it suggest that you compile and upload it with the Arduino IDE -- so there's no need for you to run avrdude directly.The Arduino IDE contains a copy of the avrdude binary, so you have it already if you have the Arduino IDE installed. Look in arduino-X.Y.Z/hardware/tools/avr/bin. This page gives and example of running it from the Arduino IDE installation:https://www.asensar.com/guide/arduino_atemlstudio/program-arduino-with-avrdude.html

It's always nice to have a back trail.I'm thinking that if the device uses something like an Arduino UNO with some kind of shield, it is pretty easy to get another UNO to experiment with.

Problem with non-genuine eBay Lightning cable - Page 1

content: Looks like this one got lost in yesterday's administration mishap, so here it is again.I go a pair of Lightning cables from eBay. They will enable charging of the phone okay but won't allow proper data transfer. On Linux I can browse the folders in the phone that contain the picture files, and see the names of the files but I cannot copy them from my phone to my computer. On a Windows 8.1 laptop I can see what looks like an *empty* folder on the phone. A genuine Apple lightning cable works perfectly for copying files to either PC in both cases. What could be wrong?

content: It depends on how they do it. If the disabled cores are just soft disabled by a part number change and the bios then in principle you might be able to do it. Other processor locking has been bypassed by pin strapping the socket or shorting jumpers on the package.But if they do it by lasering the die or a fuse there isn't going to be much you can do.

Mouse occasionally slows right down in Linux - Page 1

content: I'm using a Logitech G203 LIGHTSYNC mouse with Mint Mate 19.3 and once or twice per session the mouse will slow right down to the extent that 250mm lateral movement is needed to move the pointer across the full width of the screen. Normally it would need about 60mm. Under Preferences/Mouse the Acceleration slider is the only one that has any effect. i have to put it at max to almost get back to where things should be but it's still a bit slow. The Sensitivity slider does absolutely nothing. I've used other mice for years with no problem. Only started when i changed to this new mouse a couple of days ago. The visible position of the sliders don't change when things slow down, only the relationship between mouse distance vs pointer distance. What can i do about this?
