comment Problems starting Java Web Start program on one computer, works fine on another
@HackToHell I rolled back the question since the problem actually has nothing to to with Firefox. When I try to launch the web application using Java Web Start directly or through another program (KiCAD in this case), same error occurs.

@techie007 No, as I said, booth are using same versions of Java and on this computer the application used to work few days ago. Unfortunately, I don't know what could have happened in the mean time.

comment Wifi is slower than Ethernet cable connection?
The main point is that the 300 Mb/s is the maximum signalling rate of the interface in case you can use two channels and there isn't any interference from outside sources. There is also considerable overhead due to the way the WiFi itself works. A considerable percentage of data being transmitted isn't the actual data you're sending. Instead it's data related to the maintenance of the connection itself. In wired Ethernet, that overhead is somewhat lower.

comment Computer slow after installing 32GB RAM
@John Gilmore If this isn't solved yet, what's the condition of the HDD? Did the slowdown go away after a while? I suspect that it could be windows rebuilding swap file in order to have it big enough for the 32 GiB of RAM. In such setup, the swap file might be as large as 64 GiB.

Yes, but there's just one modem there.

comment How do I clean up COM ports in use?
The hidden serial ports don't seem the be the main cause of the issue. As expected, I found numerous instances of serial ports created by my USB to RS-232 adapter, but even when they are cleaned up, I still have 11 extra COM ports set as in use.

comment How do I link two serial ports in GNU/Linux?
The microcontroller will be later used with a GPS receiver that has a real serial port which I don't have at the moment and I want to use the mobile phone to do software development on the microcontroller because both modules emit the type of NMEA sentence I need.

comment How do I link two serial ports in GNU/Linux?
Bluetooth has support for serial emulation where bluetooth adapters of both devices create virtual serial ports which to software appear as real serial ports. Bluetooth stack of the operating system is usually used to do that and bluetooth adapters that have real hardware serial ports are expensive and (at least for me) difficult to obtain. My mobile phone has GPS receiver and software which can send NMEA sentences over the bluetooth serial port which I can receive on terminal emulator on my PC and I want to redirect that to a microcontroller which will later process that data.

Looks interesting. Is there some (relatively easy) way to say pipe capture file so that one minicom process is transmitting what other is receiving? In the worst case, even pasting a capture file into another windows could be enough.

comment What is the name for this laser printer part, and is it user serviceable?
@ArtB Do think twice before deciding to repair this printer. There are known problems with toner dust accumulating on laser lens which can lead degradation of image quality and is difficult to clean (and as far as I know Hewlett-Packard is still ignoring the problem) and the collection of toner on the transfer belt is also a problem on some units.

comment System and Interrupts causing high CPU
@muntoo Also, once you start recording, switch to drivers tab and show us what is happening there. It should show us exactly which drivers are taking most time to do their processing.

comment System and Interrupts causing high CPU
@muntoo OK. Did you try getting the newest driver for your netwoerk card from its chipset manufacturer? Which network card do you have? Check in device manager any options for hardware processing and work off-load and experiment with them. In general, having card do as much processing as possible should speed things up, but you should try turning some of the options off too, in case something isn't working correctly at the cards side. Also, post image of available settings in device manager for it.

comment What is the “real” memory of my display graphics card?
Integrated RAMDAC= Random Access Memory Digital-to-Analog Converter. It's a piece of hardware which produces analog signal which drives analog monitors. Integrated in this case should not be a problem. Integrated RAMDACs have been the norm for quite a while.

comment iMac fan is constantly spinning
Shouldn't those batteries last years? Clock batteries are usually lithium cells and it's not rare to see them hold charge for 5-8 years with no problems, sometimes even more. If it's dead, it could be a sign of a bigger problem hiding somewhere.

comment iMac fan is constantly spinning
I'm not sure. Maybe this program may help? Since it's less than a year old, it shouldn't be overheating that much, but that would depend on the amount of dust in the area. Anyway, try that program and post temperatures.

How old is the computer and when was the fan cleaned last time? What are the system temperatures? Did you physically move the computer?

comment Laptop GAINS time, why?
Are just hours wrong or are minutes and seconds problem too (only hours cold indicate time-zone switching problems)? Check your time synchronization settings, it could happen that the computer is connecting to a bad time server. If the RTC itself is bad, you'd probably get much smaller problems with time, unless it's very damaged.

comment Will my TV block my wireless router signal?
I'd say probably yes. I wouldn't be surprised if the TV has lots of internal shielding which could block the signal from the router. I've seen some TVs which had shielding all around the back of the screen and that could be a problem for WiFi signal.
