comment Why does Google call Thunderbird “less secure”?
@Nemo: if you use the remember authentication when accessing your mail in the browser, the password is exchanged for a cookie (essentially an OAuth token). Until the remember me timeout or unless doing actions that require forced reauthentication, the web client don't need to have your password or the keyring unlocked.

comment Why does Google call Thunderbird “less secure”?
OAuth is more secure because it only need to decrypt the keyring (i.e. passwords in plain text) for the very short duration while you authorize the mail agent, this is true whether you do the authentication in browser or if the mail software itself supports inbuilt OAuth authorization. If the mail software doesn't use OAuth, you'll need the keyring unlocked practically all the time, thus defeating the purpose of encryption (also your password is at risk every time you suspend or hibernate the computer with the keyring unlocked).

comment What is Windows “hosts” file alternative for OSX?
You might also need to give yourself permissions for the parent folder /etc so saving works. No, just no. That's the worst advice you can ever give to anyone.

comment Why Linux /etc/fstab UUIDs are case sensitive?
UUID is NOT a hexadecimal string, rather UUID is a 128-bit value (a 128-bit integer, if you will). The hexadecimal string used for UUID is only its canonical textual representation.

comment Is there any difference between computer speakers and a hi-fi?
This is off topic but, if you like a good sound, a good pair of earphone or headphone would be a much better way to get a good sound without spending a fortune. Unless you regularly held parties at your house, you probably don't need a speaker, and nobody cares about sound quality in a party anyway (it usually will be just too noisy to fully enjoy the sound, and if you play your sound loud enough to drown the buzzes, your neighbor will come knocking, unless you spend more money on soundproofing...).

comment I have a 3.3 Volt PCI ethernet card working on a 5 Volt PCI slot. How is it possible?
Maybe the guy who did it read somewhere that the circuitry in the board is actually a universal one, but the card is sold without a cut for market segmentation?

comment How does a server get notified about the HTTP request?
Careful, "ping" has a different totally unrelated meaning in networking. Also, why has nobody mentioned "hardware interrupts"?

comment Do hard drives really have open cases now?
It's clearly a marketing decision. A fully enclosed hard drive would be simply a beige box and very hard to distinguish from other storage technologies like SSD, CD/DVD/BR Drive, etc. Showing a product shot with the cross section of the drives makes it easier to identify that the product is a hard disk without having to read the text (keep in mind that these stores may sell to people who don't know a single word of English).

comment Installing Linux on a laptop whose DVD drive and usb drives do not work
There are Linux flavors that can be installed simply by unzipping the files into a bootable partition (e.g. Gentoo can be installed this way), but you still need to be able to modify the boot record or install a bootloader (e.g. GRUB). Note Gentoo is not a beginner's system. Can you confirm whether or not you can modify the boot record? As a last resort you can set up GRUB to be chain loaded by Windows' NTLDR.

comment How does HTTP become stateless?
@skolima: on the other hand, statelessness is the reason why HTTP is the most scalable and reliable protocol in wide use. HTTP has always been explicitly designed for scalability rather than performance (yes, they're different thing), so if you think you need hard low latency than you are either using the wrong protocol or you are using the protocol incorrectly. While HTTP2 intends to improve performance, it does so in a way that remains true to statelessness. When used for what it's intended for, I had never seen statelessness being a bottleneck of a well designed HTTP application.

comment ulimit not limiting memory usage
I knew that ulimit only work within the same bash shell for programs started after the limit is set (see how I started the program from my sample shell session), my question was that the limit still didn't work even after taking that into account.
