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).

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.
