windows 10 isn't installing on my laptop
So, a few months back, my sister accidentally dropped the laptop and for some reason, it wasn't booting up anymore. When i tried to watch YouTube videos and try to do stuff in bios, like changing boot mode and stuff, it said "no recoverable boot device found" so I figured that I'll have to install windows 10 again. I did that, created a usb installation media, and inserted it in my laptop. It's been 3 hourse, and it's just showing blank screen. When I put the usb stick in, it showed a windows logo and then it turned blank. I've been waiting for 3 hours and I'm getting kinda worried now. Any advice? My laptop has 1tb HDD, 4 GB RAM and Intel Pentium.
What is the most unreadable string which can be translated to a barcode
The reason I'm asking this is the company I work for develops an application which has a barcode reader functionality. The device we develop these softwares for has a very limited resolution camera (2MP). Now they want me to set a benchmark for the maximum length barcode pattern which is scannable. So what I'm trying to do is use an online barcode generator of CODE-128 and then feed various length strings to it. If I knew what pattern results in the most dense/unreadable barcode I'd be able to create different patterns using that.
