comment Can I get an alternative browser (Firefox/Chrome) on Win8 RT?
@Michael care to point to source that claims that Metro IE plays under the same rules as everyone else?

comment Can I get an alternative browser (Firefox/Chrome) on Win8 RT?
@yms: Yeah, I currently believe that one can use C/C++ with Windows RT (WinRT API) as long as one uses toolchain by Microsoft to compile the code. And the interface between raw C/C++ and WinRT still does not look nice. However, WinRT APIs do not allow writing a JIT compiler for JavaScript, which is a requirement for decent performance on nowadays JavaScript heavy web sites; the missing part is the ability to create region of executable and writable memory. This is the same reason (in addition to political problems) preventing alternative browsers on iOS, too.

comment What is the best computer “burn-in” or stability testing software?
It seems that StressCPU does not include sanity checks to detect hardware failures so I guess it's only suitable for testing that CPU cooling is adequate. Prime95 or mprime should be used to verify that the CPU works correctly.

comment What tools to test the reliability and stability of a newly built PC?
Computers are designed to run software and to test the stability of the system, running some demanding software is a great way to verify that the system works as designed. Make sure to use some software that really pushes the hardware and checks the results. Prime95 (or mprime) would be once choice for CPU and RAM testing.

comment What tools to test the reliability and stability of a newly built PC?
Memtest86 is usually not enough to test RAM for real. In most cases, the motherboard can supply stable enough voltage to the RAM that even a bit flaky RAM chips do work. Prime95 (or mprime) is a better choice because it puts serious CPU load in the same time. I'd suggest running some very demanding HDD benchmark in paraller to maximize the system load.

comment BSODs and Prime95 failures
My personal experience is that memtest86 can detect only very serious memory problems. I would suggest running Prime95 or mprime to test CPU and memory, instead. I once had broken memory that would cause incorrect SHA-1 sums for huge files (too big to fully fit in RAM and multiple in paraller). My best guess is that the memory was super sensitive to slight voltage changes cause by full CPU load and high multiple HDD IO usage. The problem was fixed by using pair of RAM.

comment Can I get an alternative browser (Firefox/Chrome) on Win8 RT?
@IsaacAbraham: Internet Explorer is not really an RT app. It's a "Metro style enabled desktop browser" and in non-RT Windows 8, there can be exactly one such application (your "default browser"). For Windows RT, there can be exactly zero such applications, unless the application is created and signed by microsoft. Source: brianbondy.com/blog/id/129/… and askvg.com/…

Mozilla/Firefox did whine but it didn't help: venturebeat.com/2013/03/10/mozilla-firefox-ios - Google did, too, and in the end released "Chrome" for iOS but that's really only a UI wrapper for iOS webkit (the Safari variant by Apple).

comment Can I get an alternative browser (Firefox/Chrome) on Win8 RT?
In short, the Windows RT only supports applications written using Windows RT API and that prevents using C/C++ programming languages. Unfortunately, any real world web browser is written in C or C++, including Microsoft Internet Explorer. Luckily for Microsoft, they can bend the rules and MSIE does work on Windows RT. In theory, some other browser written using only RT API could work but nobody is willing to create one (performance would suck and it would cost a fortune).

comment Intel Smart Response vs SSD as primary drive
The usual amount of writing that an SSD can take before failing is a LOT more than your rotating rust plattern HDD. If your SSD fails after writing a few TB of data, get one that has real wear leveling circuitry (e.g. Intel SSD 320 series).

comment Bad blocks detected by fsck. SMART says disk is good
Perhaps it might depend on HDD manufacturer but rest assured that at least SATA Western Digital Green series requires writing over whole a physical 4KB block at once to fix a sector with a read error (UNC). Trying to write only 512 bytes to a broken sector will result in write error. Read does nothing. You could do read-only-testing with -c to get a list of bad sectors and then selectively overwrite only broken blocks. However, that does not guarantee that the whole disk is okay because some errors show up only after first writing to the block.

fsck.ext2 or e2fsck with -cc will take LOTS of time. Expect to wait for a day per TB with a modern HDD. SMART is no good for this accoding to Google and personal experience.

comment break out of e2fsck on boot
If you don't like automated fsck that often you should use tune2fs with options -c and -C and -i. See man tune2fs for more details. Then do make manual fsck runs every now and then. The periodic checks are not only for possible file system driver errors, those are meant to detect possible hardware issues, too.

comment Linux - how to format multiple file systems within one file?
@pjc50: it's possible to do this without superuser rights: one must first create each partition as a separate file, then manually create the disk image and copy the partitions to the disk image after creating partition table to the disk image.
