Comment on Windows 7 Network Awareness: How Windows knows it has an internet connection by Dave

It needs a separate lookup for http://www.msftncsi.com because it’s distributed through a CDN and the query response will be different depending on your location. The response for dns.msftncsi.com has only one answer. They’re not checking to see if DNS is working, they’re checking to see if they get the correct answer. Some captive portals will redirect HTTP traffic but will pass DNS requests to the Internet.

Comment on Maximizing the lifetime of your SSD by Milind R

I rather prefer this kind of tech to be unreliable this way. They are cheap enough in small sizes to be affordable every year.

Average users are not the only kind of users. If they want to use an SSD, they can learn what should be done for using it best. I don't see why it will be any nicer when they are ready for "consumer usage". They will probably be locked down and void of any real tweakability just for that purpose. I say, let it stay unreliable enough that it's not a fit-it-forget-it solution. Keeps products exciting, and innovation going.

Comment on Cable vs DSL: Which Was Better? by chris williams

I find cable so much faster. Especially when watching tv online. I have created a directory of legitimate places to watch tv online. http://www.readwatchcreate.com

Consider this your legitimate source for online entertainment content. Find a book or article to read; a movie, tv series or video to watch, or learn to create virtually anything.

Comment on Building a NAS Server by Phil Veale

Phil Veale — Wed, 08 May 2013 21:29:13 +0000

I've been going through this recently wondering what to use on a NAS project I'm about to start. I have got the hardware already, I'm using a Mini-ITX board with an AMD APU and a chipset that supports 8 SATA ports, it has 7 on the board +1 eSATA. Case is Mini-ITX Lian Li with 7 "Hot Swap" trayless bays.

I'm stuck on the choice of OS. Ubuntu supports ZFS natively now, and that's appealing, but so is a more proven solution such as FreeNAS 8 or NAS4Free. I do also partly question "do I really want ZFS?" - the reason perhaps for not doing it is that the disks may well be quite mixed in size. I can't really imagine a decent ZFS config where you have 2x 500GB disks, 2x 1TB, 2x 1.5TB and a 3TB drive, for example. You're going to end up wasting a lot of space, somewhere.

I contemplated the idea of creating RAID-Zs from vdevs made of 500GB partitions, spread across the disks and then shoving them all into one Zpool but this seems messy and it's suggested the performance takes a hit. This might not play with will FreeNAS/NAS4Free either, and perhaps I'd be better off using OpenIndiana/Nexenta.

Any advice for what to do, given the changed availability of software 2 years after this article was written?

Comment on What is DNS and which Server do I choose? by user1908924

user1908924 — Sat, 27 Apr 2013 11:52:16 +0000

Well ! I would like to share my view about DNS .

DNS means Domain name Server or Domain name system.DNS helps to convert the ip address into domain name.Domain name into ip address.You cannot remember many website ip address at same time.So domain name is used for remembering the website. For example 74.125.239.17 is one ip address of Google.com.It is very difficult to remember always.So you can use domain name to view the particular website.The primary work of DNS is if you give ip address in browser ,it search for domain name of particular ip address.If you give domain name in the address bar of the browser it convert the domain name to ip address.Dns records are also taking major part in DNS.

Yes the type of data does make a difference. However the tool that I used, performed the test using the same type of data from each host device. This should've gotten rid of that issue.

Is all this information still valid for the current Windows 8 release?

For instance, isn't multi-touch support from RemoteFX? And, it seems that RemoteFX is supported in Windows 8.

Comment on Increase your Ping-Fu! by syss

I also have found this very interesting thing someday.

One thing should also be mentioned: If you try to ping an "ip" like this: 010.010.010.090 it resolves in a hostname on windows and unix. this is because the 0 at 090 normally indicates an octal number, but the digit 8 and 9 are not in the set of octal numbers anymore. So it is simply interpreted as the host 010 of subdomain 010 of domain 010 of tld 090.

on windows you can also do some very weird pings

ping ^0^x^A.^0^1^0^0.^0^0.^5^0

the caret is the escape character but in this case it does not escape anything because the following characters are not escapeable.
