comment HDD performance spikes
SSDs still suffer a penalty for random reads, but that's mostly because it reduces the effectiveness of read-ahead caching, makes it impossible to read large chunks at once, and requires more operations/instructions overall. Nowhere near as much as the scan latency of a HDD.

comment Is it possible to use aptX on unsupported computers or phones?
Depends if the Bluetooth & codec processig were implemented in user-accessible software, OS privileged software, firmware or hardware. And of course technically possible does not necessarily mean it's practical. IIRC CSR provides aptX support in Windows via a driver installation, but such a modification would be difficult if not impossible on your typical phone unless the OEM already supported it (mostly because it's proprietary and the owners don't seem to be interested in doing so).

comment WebSocket error for WhatsApp Web on Chrome on OSX
Could you double-check your proxy settings? Both system-wide and in Chrome. Also, make sure you're visiting the same subdomain in both browsers - apparently some-origin could potentially be an issue with websockets.

403: forbidden. Typically an auth failure. Try clearing your caches and cookies and trying again (or log out and in if you are able to).

comment Windows copy a large file and I halfway cancel did it copy, did it copy
Might also try locking just delete so read/write is still possible (specify "ReadWrite" instead of "None"). Just in case the DB server operates in that mode, as unlikely as it is.

Hm. The difference might be that the other file was held open by the DB server and thus could not be deleted. Could you repeat your tests after locking the file?

comment Are there desktop 3.5mm jacks that can interface with smartphone TRRS headsets?
Also, most Windows tablets and convertibles tend to support some form of control. Unfortunately, (a) it depends a fair bit on the OEM, and (b) most laptops and desktops don't seem to have that capability yet.

Would depend entirely on the device and how much of the Bluetooth stack is modifiable. If you're asking about Windows, Linux or other computer OSes, please specify. If you're asking specifically about phones, please go to the appropriate site (e.g. Android Enthusiasts, Ask Different, Windows Phone).

comment Windows says ram ran out while there are still 4gb available physical memory
@JamieHanrahan Looks like you already did (sorry, was a bit busy). Yes, overcommit is configurable, and some distros will disable it. But it looks like it was still common in 2013 and 2014, and I believe it's the kernel default when not explicitly set (by distro or by user).

Would you mind if I reformatted it to use proper headings and make subsections stand out more? The italics aren't that easy to scan.

comment Windows says ram ran out while there are still 4gb available physical memory
Possibly of interest: "just let the allocation happen and then let the references fail if there's no RAM available to resolve the page faults" is similar to what Linux does by default: it allows a certain amount of overcommit, but at some point it'll run out of virtual memory for dirty pages and that's when the out-of-memory killer kicks in... and kills what might be a completely unrelated process. Yes, nasty.

comment Why does my CPU only support 32GB RAM when it has 39 address bits?
It might be related to how physical memory is addressed. Each address is composed of details like row, channel, bank, offset, etc..
