comment Do web browsers use different outgoing ports for different tabs?
@david: It's hard to tell which one is right (or what to answer) since the Q is a tidbit ambiguous, hence my somewhat lengthy cover-all excursion. The OP is asking about the outgoing port on the client. "Client" suggests that we're talking about the source port (in TCP terms) which is the one that is freely or randomly chosen (by the implementation), but "outgoing" suggests it's really the destination port we are talking about. Which is much better described as "port on server" in layman words. Your comment on NAT is correct as seen from the server, but doesn't affect the client.

comment Run task manager (process explorer) as administrator
Preferrably, if a program needs some privileges (like most programs elevating do), say, for opening a network connection, or for going beyond its working set cap, or whatever it may be, you should know what the program intends to do (approximately, within a class of operations) and be able to allow or deny this behavior (and be able to make your decision permanent) without also allowing the program to change your browser settings, overwrite files in the system directory, or format the harddisk. Instead, you allow "changes to your computer" which is usually exactly what you don't want.

comment Run task manager (process explorer) as administrator
@RahulBasu: A system that would originally let every program do everything restricted to no-program-can-do-anything and the operating system lying about what is happening (think FS virtualization), except when the user agrees to unspecified "changes", at which point everything reverts to anyone can do anything. There is no meaningful middle ground between "nothing works" and "can fuck up the system, no safety net". That's really the most stupid thing ever (admittedly Unix worked that way for 40 years too, but that's a different thing, and they've got fine-grain control meanwhile).

comment Run task manager (process explorer) as administrator
Apart from having that annoying shortcut visible all day (hiding it breaks the shortkey) this works perfectly, thank you. I'll accept your answer as such.

comment Run task manager (process explorer) as administrator
This one "works" insofar as it really starts the process and elevates it -- upon pressing the attention sequence, exactly as desired. Unluckily, it brings up the annoying consent dialog every time. Still, it ranks among the best solutions seen so far.

a key, or a key sequence (or the secure attention sequence, or whatever). If that existed -- maybe it does and I'm just unaware --, it would be the perfect solution.

comment Run task manager (process explorer) as administrator
This kind of "works" insofar as it does indeed start Process Explorer with maximum privileges, but not really as desired, as it will cause it to launch at every start and run all the time (minimized to tray), which is undesirable. Running a system monitor consumes very non-trivial amounts of CPU. There's days, weeks even, when I don't need this functionality at all (and then, I need it 30 times in one hour). My desire is to bring it up with a keypress when there's a runaway process or such. There seems to be no way of defining a trigger (at least I've not found one) which corresponds to either

comment Using External Harddisk as an internal desktop SATA Harddisk
This is rather typical for WD. That is why I swore to never, never, never again buy one of theit products after having had a MyBookLive. Which trashed the GUI management console with an automatic update, leaving none but reset to factory as option (which fixes nothing, but also disables SSH, bricking the device). It's running Linux and using ext4, so at least all data is not lost... right? Except they use a patched kernel with a non-standard block size filesystem that no other Linux system can read. Which serves no purpose but making data recovery impossible and pissing off the customer.

comment How does Windows know if a program is not responding?
↑ This. Nothing to do with scheduling or such as suggested in the accepted answer, only whether you regularly call GetMessage (or the like) and DispatchMessage.

comment Windows 8 not detecting Wi-Fi
Routers can be configured not to advertise their SSID. If your roommates have previously registered with the network, they don't need the router to advertize itself (they already know the SSID). You,on the other hand, won't see it. Check router settings. Also be sure that your computer supports both the frequency band (2.4 or 5 GHz) and the 802.11 flavour (like, b, g, n, ac, ...). Network cards do not necessarily support all of them, and routers are often configured not to use all of them (since mixed mode runs at the slowest mode that anyone uses).

comment How secure is the Windows clipboard?
@ColonelThirtyTwo: You mean that e.g. having an invisible input field and doing document.execCommand('paste') won't work? I haven't tried (not being a malware author, nor really being interested in someone else's passwords), but I guess it should work.

comment How secure is the Windows clipboard?
Of course the threshold is much lower for malware that reads the clipboard (an entirely "legal" piece of javascript embedded in a web page will do) versus malware that exploits the browser process or reads another process' memory, or installs a hook to capture keypresses, etc.

comment If my taskbar turns to a light blue color, does that mean I've been hacked?
When a game (say Fallout) switches to fullscreen, desktop effects are switched off, that's normal. About what causes the behavior on the OP's machine, I wouldn't know. Just saying that "downloading lots of files" doesn't provide a valid reason. Back in the days, I've used Pentium III computers with 64MB and run webservers on Pentium IIs with 8MB on a 100mbit/s internet link, no problem whatsoever (the malware built into Kazaa could very well bring a computer down back in the early 2000s, though - if running P2P services counts as "downloading a lot" - maybe that's just it).

comment If my taskbar turns to a light blue color, does that mean I've been hacked?
I don't think that is a sufficient explantion. Aero effects first and foremost consume GPU resources, neither a lot of main memory nor CPU. Also, no matter how harsh one downloads stuff, it is very difficult to get over 6-8% CPU usage and 20% or so (everything included, the actual downloading takes maybe 0.5%) RAM usage with just downloading some stuff. Unless this laptop is 20 years old, the idea of a download consuming too many system resources is just ridiculous.

comment SSD upgrade underperforming
The numbers from your other computer shown in the " the kinds of speeds I expected" screenshot (which runs on SATA-600) are physically impossible with SATA-300. Your SSD is quite "OK" for an elderly cheap SSD which is almost completely full (nearly reaching the theoretical maximum on sequential read). It only really sucks at small writes, but again for a cheap disk that is not surprising.

comment How to bypass “This app has been blocked for your protection” error
No, turning off SmartScreen is really the better option, since it's total crap. SmartScreen is a misdesign (just like the on/off UAC in Windows) and conveys a false sense of security, which is worse than no security -- instead of being wary about what programs to run.

comment Can a massive MySQL data import on an SSD damage it?
@MichaelKjörling: Thank you for your very valuable input. You did of course read and understand the answer, didn't you? The relevant fact is that SSDs have physical block sizes which are much larger than that, regardless of the logical sector size (which I've seen anywhere from 500 to 4096 bytes, even non-power-of-two sizes). No citation needed.

comment Making a Synology diskstation accessible via WLAN
@FrankThomas: Well, the reason why the 2-bay NAS is locked in a cellar room behind a steel door is that I'd like it to keep a backup for the case when the whole place burns down. So, moving it upstairs won't do (though so far I'm indeed taking it upstairs every 3-4 days, plug an ethernet cable in, and run the backup. That's... sub optimal). Ideally, I'd like this to happen via cron every night, without me even thinking about it. So a typical $20 AP should do in your opinion? I'll try that, thank you :-)

comment How can Windows dump the complete RAM in the hibernation file so fast?
@PeterMortensen: No, I really mean gather write (as opposed to scatter read). This means writing to a single file while gathering the data from multiple locations. You supply an array of structures each of which contains a start address and a length (with strict alignment requirements). The operating system passes these to the controller, and the hardware does the rest.

comment find/xargs, filenames with spaces, and quotes
Given Windows and no Perl installed, that's unluckily not an option, did it manually by splitting a file.
