well, when they define layers as you know they mean like fields and within them fields.. DNS doesn't carry HTTP.. nor does HTTP carry DNS.. So they're same layer.
yeah bad example there; but basically SMTP wouldn't be anything useful without DNS, so if nothing else SMTP depends on DNS (unless you're just sending email within a LAN)
most mail servers will let you send email on 10.0.0.0/8 or 192.168.0.0/16 (or the other one I always forget)
so you could send from [email protected] to [email protected] and it'd just pass through the router and directly interface with the remote mail server... like a simple client-server protocol like telnet
I have never done an in-depth analysis of the differences between TLS and SSH in terms of their capabilities, supported ciphers, security, etc... though I generally prefer TLS with client-side certs, PFS, and mutual verification (client verifies server and vice versa)
it provides a neat type of authentication too if you make both sides verify a specific certificate, not just any old one signed by the CA
Out of curiosity: How many of you find exposed PCBs scary?
...as in those found in disassembled electronics that are not meant to be handled by the user, and not necessarily things like video cards and memory modules intended for end-user installation
@DragonLord it always strikes me as fascinating that most of the devices we use today constantly rely upon microcontrollers and other such invisible, embedded ICs that perform important functions, faithfully, and usually are not the cause of product failure
in that case, the battery cell will wear out long before that IC will give up the ghost
when I got my first computer at 6 (more like when my parents got it and I started to experiment with it), you needed either a cluster of computers, or an extremely expensive ($15k+) machine to get the kind of MIPS that little Holtek microcontroller is capable of
and my smartphone's SoC would exceed the processing power of entire state-of-the-art research facilities of the time
@allquixotic, it never ceases to amaze me how much technology has advanced over the years
15 years ago, a 3.5-inch desktop hard drive could store around 10-15 GB of data
Today, you can get almost 200 times that amount of space in a device that fits in the palm of your hand
...or a device with about 50-100 times as much storage in the same or even smaller form factor but is capable of tens of thousands of times faster random I/O
...and over a thousand times faster than even today's hard drives
I've had a few button-related issues with the Kone XTD--within two months, Newegg replaced the first unit, and Roccat replaced the second one under warranty
The third one has been working just fine and I haven't had any major issues after more than a year of continuous use
The Acer external display is IPS, while the laptop's built-in display is (probably) SVA. The backlighting quality is probably better on the laptop display ;p
I'm not a huge chess player, but it's amazing how much chess engines have advanced over the years and especially the last 18 or so months.
The open-source Stockfish, in particular, recently reached the top of the chess engine rankings.
Although new versions of commercial engines are now almost just as powerful, the key to this success is a distributed testing framework where computers play tens of thousands of games to validate each patch
Unlike most chess engines (even other open-source ones), which are developed by a few people, Stockfish accepts contributions from the community and the core developers are able to quickly determine whether a patch improves playing strength
Anyone can contribute their CPU time to the Fishtest testing framework, just like BOINC projects and Folding@home.
It's truly a revolutionary development in computer chess technology and it exemplifies the advantages of the open-source model.
The testing framework is especially busy lately because a major computer chess tournament is currently in progress (engines can be updated between stages, and the Stockfish team submits the latest validated nightly build for each stage)
Just goes to show how open-source is often better.
@JourneymanGeek I am using 64 bit windows 7 ultimate but feel i am not using it to its max(i.e. the vitual drive mount etc.)
mine is a 4 GB RAM so i paired it with a 64 bit Win 7 as it will support the speed but what i want is how can i implement those features like virtual disk management,
@JourneymanGeek Yea, but traditional USB has been somewhat more forgiving. As soon as you try to do more with it, you also need more from the hardware.
I need to use an API. I want to do the programming in PHP, but I have no idea where to start. I contacted the creator of the API asking
how should I use API's in general?

SMTP doesn't care if you started with a domain name or not.
You need the IP of the SMTP server, and you need a destination mailbox.
That's all.
Heck, the dest. mailbox might be optional.
DNS is only involved if you send an email to a domain, in which case a DNS lookup is performed to look for the MX record associated with the domain for the correct mail host. If there is no MX record, it falls back to the A record anyway.
So when I look around on the airport, I don't really see many differently shaped airplanes.
They all look pretty much the same, only subtle differences.
Why is this design so common? Why don't we have more extravagant designs?
Or am I not looking closely enough to appreciate the differences...
-_______- @Bob Koss today unleashed their own original brand of bluetooth headphones. the physical design looks fine/good, but 8 hours of runtime on the battery. lulz
@root if it were buggy and had some kind of a problem, you'd want to disable it to avoid the consequences of the bug
jack detection just lets the software take some action when it detects (or thinks it detects) something plugged into an analog jack (digital protocols usually have explicit protocol-driven detection)
My motherboard is a Gigabyte GA-H87-HD3 and I was having the same problem of Realtek HD Audio Manager not detecting speakers in the front panel. After trying all kinds of solutions and reading the MB's manual dozens of times, I found out it was simply a matter of checking a checkbox!
Double-clic...
> If you still have no sound, maybe this more technical answer could enlighten you.
The correct one to use depends on your case. Those cables are typically used to connect front panel headphone/microphone ports. While the connectors may look identical, the pinouts are different and not really interchangeable. The matching connector on your case should be labelled accordingly, I ...
No, Twitter, I've never met ASUS North America. I bought some of the products he makes on Amazon (or is it a she?) but we have never been formally introduced. Where can I go to meet Mr(s). America?
that's almost as good as the emails I get "from" Barack Obama
probability of Mr. Obama actually authoring the text of those emails, much less being aware that it's being sent specifically to me? 0%
oddly enough, while corporations have been getting closer to being human beings, certain human beings have been getting closer to being corporations
the idea or concept or personality of Barack Obama, controlled and groomed and developed by a team of hundreds, writes me emails... they might as well be from the human being of the same name.
my dedi runs SmartOS on the host, and most of the guests are Solaris Zones, which are completely isolated virtual machines but instead of a hypervisor, the guests use the actual host kernel
so only one Solaris kernel is running on the system -- but, due to PhantomJS build problems on SmartOS, I had to install Cavil into a CentOS 7 hypervised guest (on top of KVM)
@jokerdino original "UNIX" (from AT&T) birthed System V Release 4 ("System Five Release Four", abbreviated SVR4), which birthed Solaris -- a UNIX-based OS developed by Sun Microsystems -- which later birthed OpenSolaris, an open source release of Solaris -- which later birthed Illumos, a fork of OpenSolaris after Oracle dropped upstream OpenSolaris -- which later birthed SmartOS, a fork of Illumos with a NetBSD userspace.
and the fun part is that whenever my hosting provider (OVH) updates the global zone with a newer kernel, all I have to do is reboot the physical OS and I've got an upgraded global zone :D
one of the best things about Solaris is that it properly prevents you from mucking things up, especially in the global zone (the host OS), by making most of userspace read-only
keeps things nice and stable when you can't install junk into the host
honestly, for most stuff, the advancements in the kernel have been fairly minor and incremental outside of the areas of virtualization, graphics drivers, network drivers, and filesystems
if you have problems (performance, bugs, features, etc) in those areas, you need a new kernel; otherwise, no
since the mid-2.6 era, the rest of the kernel hasn't dramatically changed "across the board" perf very much
hmm. maybe I could try running OpenVZ on top of CentOS 6 as my physical host (ugh @ not using the latest stuff -___-) and make my guests all CentOS 7 VZ containers, since CentOS 7 is supported in CTs on CentOS 6
that would at least get me back on a Linux kernel (though, do I really need that?)
it just seems so fucking untidy to have a bunch of Solaris Zones, and then Cavil's KVM Linux guest sticking out like a sore thumb
