Laptop Model: Sony, Vaio SVE141D11L
Hi! I have two problem. first is when I turn on my laptop I see this Operation System Not Found, and the second problem is, I can't boot bios page, because my keyboard is not working. so, now how can I fix my problem? I mean how can I get into the bios page?
not sure why your keyboard is not working, could use more information - best way to access bios would be to plug in a basic USB keyboard and press key as says on bios screen.
Wireless keyboards/dongle keyboards most likely will not work.
Some other easier things you could try:
It sounds like your memory device(HDD/SSD/M2) might still be working but OS is corrupt so insert an OS installation media (usb, cd etc) if your on Microsoft windows you can get an windows iso tool online, as your computer cant detect OS it should boot into any bootable media.
open up your laptop remove cmos battery for over a minute which should reset your bios in-case keyboard is messed up due to settings
remove your internal media device and plug it into another computer to check if its readable.
Hope this helps

I have trying to learn how to do some basic networking and I have having issues using Putty. I am Connecting my server computer to the RS-232 via ethernet, and able to get the command prompt to display. However if i press enter, any characters or numbers I get nothing.
I've tried messing with the setting to see if i have something disabled. That hasnt worked for me so far, i also tried setting the speed from the default to 115200 to see if that would work either.
Am i missing a step that i need to do?

on my raspberry, I installed "motion" (the one with daemon) for my Pi Camera. However, I set up the Motion with the port 8081. If I open it on the raspberry using localhost:8081 it works but unfortunately with a big delay/lag. Maybe if you find a solution to this would be awesome. But my main problem is that if I want to open the server on my Pc by entering 192.168.xxx.xx:8081, it won't open at all. Using the IP without the port it still works. Maybe you find a solution.
The lag you encounter on Raspberry pi is because that same raspberry is processing the video input, and now you want to add processing of showing you that stream, after all, it is raspberry, no big deal there.
The Motion config file (/etc/motion/motion.conf) haves a setting named "Stream_localhost" by default it is set to ON, make sure you change it to OFF.
If you have any other problems I believe this simple instruction will help you.

EDIT:
After quick google searching I found out that two more settings must be set to off also
webcam_localhost off
control_localhost off

I am trying to install Raspbian on Pi 3 but when I connect it to my monitor using Hdmi the screen is just all black and it doesn't say anything. I've tried searching online but all the answers I found I got confused, since most involve connecting using ssh or something while I can't even get it to turn on to connect it to wifi.
Look for a flash of green near the power led after you plug in the power, that should indicate its booting up okay. I'd suggest verifying the install on your sd card, flash another card and try that. Ensure the power plug you have is good quality and supplying the correct voltage.
Pre-answer: you might want to verify the install on the SD before spending too much time with blind boots.
Easy answer: use a wired usb adapter (preferably with an alternate source of power), then ssh and run raspi-config as I'm sure you've already read.
Moderate answer: stick the SD card in an adapter and edit the /boot/config.txt file. See here for syntax.
Advanced: Edit files as in moderate answer above, but this time target crontab to add a script hook that connects to wifi, thus allowing ssh.

my virtual machine (VMware macOS) doesn't see my iPhone when I connect my iPhone to the computer. Anyone knows how to handle this ? I want to connect just for using my iPhone as simulator.
I think that your iPhone with the lightning connector would be perceived by VMWare as a USB Device, so you could refer to their USB Device documentation. The TL;DR is essentially:
Add the physical usb port to what the vm can "see".
Choose VM > Removable Devices to connect specific USB devices to your virtual machine.
Find the menu item for the usb port the iPhone is plugged into and mouse over it to see the iPhone, then click its name.
I found some additional instructions here which may provide more useful, granular details on how to do this. Pleas note that you will have to take into account the OS of both the host and the guest when following the documentation. Additionally, you may need specific drivers to let the guest addition recognize the iOS device.
Good luck!

My LCD rotates. The software that comes with my ATI card to rotate the desktop just crashes (I've uninstalled, reinstalled and rolled them back, still crashes). Is there any other way to rotate a Windows XP Desktop by 90 degree increments? I am looking for either software or code (any language is fine.) I know I have seen 3rd party support for this before, but I can't find it now.
I realize this may not be a strictly software development related question, but it is programmer productivity related. If I can get an answer that involves how to write a program to do this, even better!
IRotate: http://www.entechtaiwan.net/util/irotate.shtm.
Have not used it but heard good things.
Same people that make Powerstrip http://www.entechtaiwan.net/util/ps.shtm.
Which gets rave reviews from the HTPC crowd.
Was looking at these recently while researching stuff for an HTPC.
Both are try before buy shareware.
I hate to give you the answer you probably already know, but yeah this is a video card driver software thing and if the ATI software crashes then it's either corrupted or buggy or your Windows install has gone rotten.
I've done this before on my NVidia-based cards without issue. I've never owned an ATI card.
iRotate worked great, and it is free for personal use. Very quick and painless install. Thanks seanb. My only complaint is it binds hot keys to CTRL+ALT+[arrows], so I have to close it after I rotate. It seems to stay rotated, but I guess I will see what happens when I reboot.
XP with SP3 has a known issue with ATI video cards where it will not rotate the desktop.
I'm thinking I might go back to SP2 to get that back.
Right-click on Desktop
-> Graphics Properties...
-> Display Settings
-> Enable Rotation
-> 90 degrees
Well, it works on my laptop (XP Professional, SP3).
