] | Short answer: No.
Long answer: Games actually aren't all that complicated. It depends on what you're talking about when you say "games" but the two contenders for most complex games would be 3D games and online games (particularly massively online games).
The complication in 3D games comes from taking a model of a world and rendering it in 3D and to have it behave in a "realistic" (within the rules of the world) way. Creating a visual and auditory environment from that isn't actually that hard. It's pretty much all linear algebra and is a mature field of computer science.
The real trick comes in making that process performant in real-time. Over the years game programmers have had to make a LOT of tradeoffs between realism and performance (eg if you can make a performance algorithm that'll generate realistic looking trees that's actually worth a lot of money). So games have naturally gotten better (visually) over the years as computing and graphics power has increased.
Now some game programmers have made real innovations in this field that have (rightly) earnt them a lot of money. John Carmack (id Software: Doom and Quake) and Tim Sweeney (Unreal) spring to mind.
The real cost however in making games is the content. Just go look at the credits for a modern FPS (first person shooter) game and you'll typically see as little as 6 programmers but there'll be 30-50+ artists. Content isn't complex (from a software point of view). It's just time consuming.
As for online games, I remember when Everquest came out and people raved about how hard it was. Bzzzt, wrong. For those (like myself) who were familiar with the development of MUDs (mutli-user dungeons) through the 90s (and possibly 80s), architecturally an Everquest server wasn't that complicated.
Same goes for World of Warcraft or any of these other games.
If you want to talk about complex, how about the Windows XP operating system these things run on which has an estimated [40 million lines of code](http://en.wikipedia.org/wiki/Source_lines_of_code)? God knows how many Vista has. Or what about the Linux kernel?
Now in government, the military and the private sector you'll find other applications that have literally thousands of man years invested in them. | I would think engines that applications run on top of would be complex. Probably not a lot of lines (like an OS) but very complex as it would need to handle all of the elements and scenarios the designer would need to throw at it AND run optimally.
Since you're talking games, many game developers buy engines and write against that. Some of these engines are written so openly that they're used for several apps that look and feel totally different. |

] | I'll tell you what I think is most unique about game programs, and what to me makes them maybe the most impressive...is how bugs affect the overall produce. If you have a bug in say, Outlook (hah), there are a couple different ways to address it (I'm going to oversimplify here):
1. Fix the bug.
2. Give the user a workaround, if there's another way to accomplish the same thing.
3. Just leave the bug as is, ship with it and don't worry about it.
With most games, especially anything that is multiplayer, you often don't have the option of #2 or #3. Players look for ways to exploit games, so if you leave a bug in that can be taken advantage of, it will be. Thus, the tolerance for bugs in games is actually much lower than in most business/productivity software, because of the abusive potential.
To me, this is one of the major things that makes a large, complex game system like WoW or Everquest really impressive. The lengths to which people will go to abuse any loopholes in a game are pretty amazing, and very well documented. This is a very stark contrast with products like Photoshop or office software, where as long as there is some way of accomplishing what you need to do, the fact that some of the other workflows are maybe broken is not necessarily a mission-critical flaw...it at least has the potential to be ignorable. That just isn't a luxury that game developers have.
Now...compared to things like Air Traffic Control or Airbus flight software, games don't have anywhere those type of life-on-the-line restrictions...that's a whole other class of challenges. | Apart from some excellent suggestions above, I'd like to point out that [Uniview](http://www.scalingtheuniverse.com/) is rather impressive. |

dwarf fortress actually is quite impressive. it may lack shiny graphics, but it does a lot of impressive stuff in open world generation and simulation. | Short answer: Yes. Although I'm answering this question: "I was thinking today about what **could** be the most complex / impressive application ever written." rather than which **is** the most complex / impressive.
Imagine trying to develop a game that modelled the entire universe and allowed you to play it with [x] superpowers. Effectively, you can turn a game into a simulation of ANY complexity, up to as complicated as all known physics and then throwing non-physics into the mix! A video games, by its very nature, can be as simple or as complex as you want to make it.
To my mind that's the beauty of games development. You can create a world to whatever level of detail you want. Anything you can imagine, you **could** turn into a game. Theoretically. |

As far as computation goes, they certainly do a lot but it's mostly just a lot of tried and proven algorithms running on ever-increasing numbers of polygons and higher resolution texture maps.
Simulating a physical environment isn't all that hard either; provided you want the environment to obey the known laws of physics because most of that stuff is somewhat basic and well understood.
The Mars rover missions are an impressive feat. No dynamic memory allocation, debugging the code while it was running, **on Mars**, and uploading a fix for a bug, on the fly.

205,781 | I was reading up on electrostatic particle accelerators when I read a statistic stating the efficiency of converting wall electrical power (the electrical power from the outlet) into beam power in an accelerator. I tried finding out why this was the case and doing some first cut calculations. The most I could come up with was a lot of the power gets wasted by particles not being efficiently collimated, I.E. most of the accelerated particles hit the wall. Now, I'm pretty sure that is not the only reason, I assume depending on the quality of the vacuum, scattering by the leftover gas molecules would also contribute to the lost beam power, as well as losses via emitted radiation from focusing the charged particles with magnetic fields.
Am I getting this right? Or am I missing some huge power draw that sucks most of the power away from the beam? I know the efficiency depends somewhat on the beam maximum energy (since higher energy beams have higher brehmstrahlung and cyclotron radiation losses), I'm looking at the power efficiency of a 10 MeV electrostatic electron beam accelerator.
Why are 10 MeV electron electrostatic particle accelerators so inefficient? | 2015/09/08 | [

] | As one data point for linac efficiency, I found a nice presentation from a Jefferson Lab meeting (where CEBAF is - Continuous Electron Beam Accelerator Facility). This is from Googling 'energy efficient linac'. In it, they quote that the CEBAF klystrons are about 25-28% efficient, while their new solid state amplifier proposal (an SBIR, can see at [Far-Tech, I have no affiliation other than Googling them](http://www.far-tech.com/ssa.html)) is 55% efficient. This is at 1497 MHz, and 6.5kW linear mode amplification.
Now, that ignores efficiencies in the electron source, focusing elements, steering plates, and all the vacuum components (a 300 liter/sec turbo plus backing runs about 700W). It also ignores production of cooling water and so forth, that will contribute to the overall (in)efficiency (and you will need lots of cooling of whatever target you are trying to get gammas out of). We won't even go in to the electron-to-gamma conversion efficiency, much less how you are realistically going to extract energy from the gamma beam on the other end. | The 'electrostatic' accelerators don't recycle the current, I suspect. This
would be a pelletron or Van de Graaf design, and current going through the free electron laser
magnet structure (undulator) then hits a target and dissipates all the energy
it didn't lose in radiation. Hitting the target dumps all the kinetic energy.
A synchrotron, on the other hand, takes bunches of relativistic
charges and moves them through that same undulator once per cycle, circulating
at near lightspeed, so a tiny amount of the beam kinetic energy can be lost
due to radiation reaction, but built back up by the accelerator sections
elsewhere in the apparatus. Those sections use timed RF in the right
phase to re-accelerate the bunches back to full speed, and until the
charges hit gas molecules and scatter into a beamtube wall, that
beam can remain circulating for hours between fills.
A static field just makes a current from HV to ground.
Circulating is more efficient use of fast-moving particles than dumping
them into a grounded target; the synchrotron electron gun can be turned off after startup,
but the Van de Graaff has to put new electrons out continuously. |

If you replace the zener diode with a pot in series with a fixed resistor, you have an adjustable zener. The circuit often appears in audio power amplifier designs, where you can adjust the voltage spacing between the output transistors to set the no-signal static current through them.

This is not a particularly great idea, as you'll be wasting energy as heat - and that's a rather expensive energy, since it comes from an ICE.
A switching buck DC/DC converter would be ideal, but a linear regulator can do the job as well, while wasting less heat than a shunt would, especially at lighter loads (e.g. when the battery has charged up).
In essence, all you need is a linear regulator with reasonably low dropout, set to 13.8V. The circuit below does this:
[simulate this circuit](/plugins/schematics?image=http%3a%2f%2fi.stack.imgur.com%2fadYfE.png) – Schematic created using [CircuitLab](https://www.circuitlab.com/)

The average power dissipated on the pass element and the Schottky series diode, with a 10 Ohm load, is a couple Watts total:

With two mosfets, rectification can be active, for lower dropout, but most likely this won't be of any advantage in this applicaiton:
[simulate this circuit](/plugins/schematics?image=http%3a%2f%2fi.stack.imgur.com%2fglI6G.png)
A battery charger of this kind also requires active current limiting, to protect itself, the load, and the generator's winding from short circuits and overload.
The easiest way to get such protection is with a thermal circuit breaker. It could also be implemented electronically.
One way uses the series rectifier diode as a current sensor. A second, matched diode, running at a small constant current, needs to be thermally coupled to the rectifier diode. The difference between these voltages is a measure of the *logarithm* of the current ratio between the two diode.
Another approach is to use the Rds(on) resistance of the mosfet. This is straightforward when the mosfet is fully turned on. With two mosfets, we can decouple their control and use one as an ideal diode, acting as a current sensor when turned on, and the other as the pass element. The ideal diode doesn't require a heatsink, since it has negligible losses - this way it also stays at a temperature that's relatively independent of the load current. Then we don't need a third reference mosfet to establish Rds(on) scaling. |

] | **Short Answer:**
Data-link-layer (layer 2) technologies that use MAC addresses use ARP, even for "external" (WAN) links.
Data-link-layer technologies that are point-to-point don't necessarily need link-layer addresses, because there are only 2 endpoints, and each endpoint knows that if it's not the one transmitting the message, it must be the one supposed to receive it, and vice-versa. So they don't need anything like a MAC address or ARP.
Data-link-layer technologies that are multipoint-to-multipoint on a shared medium will need link-layer addresses of some kind, and an address resolution protocol of some kind, even if they don't call them "MAC addresses" and "ARP" respectively. But they often do call their ARP-equivalent "<this data link technology's name> ARP"
**Long Answer:**
In one sense, MAC addresses and ARP as you know them from Ethernet are only used on Ethernet-like data links, so finding the next hop MAC address is only necessary on Ethernet-like data links, and ARP is used for that.
Point-to-point serial links (as many business WAN links are) don't necessarily require data-link-layer addresses, because there's only one other device you could be talking to, because there's only one other device on the line. So you can assume that everything you receive is for you, and you can assume that the other endpoint of the link will process everything you transmit.
So what about multi-device (a.k.a. multipoint-to-multipoint) shared medium data link layers that aren't like Ethernet, and don't use Ethernet-like 48-bit MAC addresses? Well, those data links probably have some kind of link-layer addresses even if it's not a 48-bit MAC address, and they'll need some kind of way to map IPv4 address to their data link layer addresses, even if it's not traditional Ethernet ARP. In general, the people designing how to make IPv4 work over those other data links basically follow the Ethernet model and create an ARP protocol for their data link. These protocols are usually differentiated from traditional Ethernet ARP by being named "<insert name of data link layer protocol here> ARP".
So if you do IP over Fibre Channel, there's "[IP over Fibre Channel ARP](https://www.rfc-editor.org/rfc/rfc4338)" (the simpler name "Fibre Channel ARP" or "FARP" was already in use for one of Fibre Channel's own protocols).
If you do IP over SONET/SDH (technically over "MAPOS", which is the way to do multipoint networking over SONET/SDH), you have "[MAPOS ARP](http://tools.ietf.org/search/rfc2176)".
If you do IP over FireWire (the IEEE 1394 Serial Bus), you have "[1394 ARP](http://www.ietf.org/rfc/rfc2734.txt)"
If you were time warped back to the early 90's and wanted to do IP over AppleTalk/LocalTalk, you do "[NBP ARP](http://tools.ietf.org/id/draft-ietf-appleip-MacIP-02.txt)" (the simpler name "AppleTalk ARP" or "AARP" was already used for the protocol that maps AppleTalk's network-layer addresses to data-link-layer addresses). | >

Simplifying a bit, it's not possible and not needed.
In the simplest situation, a node has a NIC that is assigned an IP address and a netmask (i.e. subnet) and it knows of a "default gateway" that it got through DHCP.
Based on this, if it wants to send traffic to something in that same subnet, it can just throw the traffic out of that NIC and it will reach anything on that subnet.
If it wants to send traffic to any other subnet, it needs to send that traffic to the default gateway, which is on that subnet.
The default gateway will then forward (routing = forwarding) that traffic to another subnet if it has a route for it. In your typical residential situation, that will basically go to your cable or DSL ISP's router, and further on "upstream" from there.
Big networks (corporate, campus) use various gateway protocols to find out about routes that they are not directly connected to automatically, and ISPs use BGP to trade the rather large routing tables that make up the entire Internet.
The MAC is not needed for routing, just the default gateway.
MAC addresses cannot help in routing, because there is no such thing as a "subnet" for MAC addresses. The "MAC address layer" assumes that when it sends something to another MAC, it can do that just by throwing traffic on the wire. It has no concept of "middleman." So getting the MAC address of anything off your network is not helpful insofar as getting your traffic to it. This is why the IP layer exists and not everything is MAC addresses only. |

Your router will use ARP to lookup the MAC address of that default gateway. Then that router will do the same to find its "next hop". | >

Simplifying a bit, it's not possible and not needed.
In the simplest situation, a node has a NIC that is assigned an IP address and a netmask (i.e. subnet) and it knows of a "default gateway" that it got through DHCP.
Based on this, if it wants to send traffic to something in that same subnet, it can just throw the traffic out of that NIC and it will reach anything on that subnet.
If it wants to send traffic to any other subnet, it needs to send that traffic to the default gateway, which is on that subnet.
The default gateway will then forward (routing = forwarding) that traffic to another subnet if it has a route for it. In your typical residential situation, that will basically go to your cable or DSL ISP's router, and further on "upstream" from there.
Big networks (corporate, campus) use various gateway protocols to find out about routes that they are not directly connected to automatically, and ISPs use BGP to trade the rather large routing tables that make up the entire Internet.
The MAC is not needed for routing, just the default gateway.
MAC addresses cannot help in routing, because there is no such thing as a "subnet" for MAC addresses. The "MAC address layer" assumes that when it sends something to another MAC, it can do that just by throwing traffic on the wire. It has no concept of "middleman." So getting the MAC address of anything off your network is not helpful insofar as getting your traffic to it. This is why the IP layer exists and not everything is MAC addresses only. |

] | By "external network", I'm assuming one that isn't directly connected to your router.
It doesn't ARP. Your router looks up the target address in its routing table. The table will list a next hop address, which is the address of the next router to get closer to the target. your router will then ARP for the router address, because it is on the same network as your router (or to put it differently, they share a common network).
Now, it is possible that the next hop address is not on a network that your router is connected to. So your router looks in its route table to find the route to the next-hop address. That route will also have a next hop address (we'll call it NH2). NH2 will be on a common subnet, so your router will ARP for the MAC of NH2.
In the really bizarre case where NH2 is also not local, your router will continue to look in its routing table until it finds a local subnet, or it will drop the packet. | >

Either the next hop is reached by Ethernet or not. If by Ethernet, then ARP works. If not by Ethernet, then no MAC is needed. |
318,395 | I am a 12th grade student from India. I was taught electrostatics before gravitation. I know that if in a uniformly charged sphere, a cavity is cut out unsymmetrically like towards an edge but still enclosed within the sphere, a non zero constant field would exist in the cavity. This doesn't violate Gauss's law as well. When a similar situation in gravitational, where a uniform mass density sphere has a cavity similar to the cavity above, a field does exist inside.
[](https://i.stack.imgur.com/yhqiom.png)
However, I know that gravitational field has only sinks and no sources. Field lines appear from infinity and end on an object having mass. Inside the cavity, since its enclosed, infinity doesn't exist inside there. Then how does a field line originate inside there? This wasn't a problem in electrostatics as positive charges act as sources and negative charges act as sinks for the electric field. Also charges can induce, and form the necessary negative or positive charge on the surface for the field, so we can consider the field line inside it as arising from a positive charge and ending at an induced negative charge. But I'm pretty sure masses cannot induce, correct me if I am wrong.

] | Great question. Your charged sphere for the electrostatic analog does not have to be a conductor (no induced charge necessary). In other words, charge does not need to rearrange itself in order to satisfy Gauss's law (in this and all scenarios).
But this raises the interesting point, how can Gauss's law be satisfied if they are no apparent sinks? Think of two positive charges, if one the charges has a charge greater in magnitude, the E-field will naturally tend away from the charge that has a greater positive charge. However, like you aptly point out, the E-field will not have a sink near the surface since as one approaches the surface of the charge, (or surface of cavity) the E-field approaches infinity. Since Gauss's law cannot be violated, this lends itself to the idea of infinitesimals.
As you approach the surface of the cavity, the E-field will not diverge to infinity, but instead converge and approach a constant value. In some places near the surface, the E-field will diverge outwards, in other places the E-field will converge inwards. I know this is not the answer you wanted -- you wanted a more intuitive reason -- but Gauss's law cannot be violated, and if you were to do infinitesimal calculus for the cavity, (knowing its charge distribution) you would necessarily need to get a converging E-field, one that pointed inwards and outwards in some places. This is the same reason why the E-field near the surface of a spherically charged shell converges. (Note: I accidentally wrote this assuming you were asking about a positively charged non-conducting cavity, but the reasoning is the same for a cavity where gravitational fields are being examined). | When thinking about gravity in terms of field lines, you're right: all lines originate from infinity. However, they do not all terminate at the surface of your massive object. As you descend into your object, the gravitational field gets weaker: some field lines terminate, but others continue down in accordance with the amount of mass in each shell. The last field lines terminate in the center, resulting in zero field there.
In the cavity, some field lines have simply not terminated yet. They continue unhindered through the cavity and begin terminating when the reach the inner wall. There is no "induced mass" on the inner surface of the cavity.
I think some of your confusion came because you're comparing an electrical conductor to a gravitating mass. In conductors charges move freely, resulting in all charge accumulating on surfaces with a neutral interior. There is no such thing as a "gravitational conductor," gravitating mass is more like an insulator. A uniformly charged insulator would behave exactly as the gravitating mass you're considering. |

34,825 | In *King Pin* (1996), during the first scenes we see the protagonist having trouble with his car, so he takes it to a mechanic.
The mechanic wastes no time spotting the problem. He even dips his finger in the fuel (from the fuel pump or another part of the engine that had fuel) and puts it into the mouth of the protagonist for him to taste the sugar.
It is later revealed that Bill Murray's character poured a bag of sugar into the fuel tank.
The question is: How did the mechanic reach the conclusion that sugar was added to the fuel? If it was sand, it could have been possible to detect because, unlike sugar, sand does not dissolve into liquid.

This should work for Windows 7 as well.
Additionally, to prevent troubles when running stuff via AppLocale ("AppLocale was unable to launch the specified application. Please make sure the application specified is valid.") you'll have to [set it to always run as an administrator](http://www.mydigitallife.info/workaround-to-run-non-unicode-legacy-setup-or-installer-with-applocale-in-vista/):

* Log out
* Log in with your usual user.

] | I make websites both using Drupal and [Django](http://djangoproject.com) - sometimes with [Pinax](http://pinaxproject.com) (Python). So let me try to set up the differences between Python and PHP, and the different CMS's.
**Python - PHP**
* Pros for Python.
+ You tend to write more readable code making it easier to maintain. This has a big impact if you are going to do a lot of custom coding, now or in the future. However if you aren't going to make that much custom functionality, this doesn't matters.
+ Python and Django is buildt on OO, making it easy to reuse code, and is built on the [DRY](http://en.wikipedia.org/wiki/DRY) princip.
+ I find, that python is more intuitive to program in. In many cases it has a less weird / obscure syntax than PHP.
* Cons for Python.
+ PHP is easier to host. More providers will allow you to run PHP and you can generally find PHP hosters a bit more cheaper than python hosters. If you have your own server, this wont matter.
Generally it's easier to code with python in many regards, but this is something that can be overcome simply by using more time with PHP. Also if you don't know python, that means you will have to invest some time learning it, and the things you can do with python. On the other hand it's a bit more difficult to find cheap hosting for Python projects.
**Django/Pinax vs Drupal vs Wordpress.**
It's always difficult to be able to say, which CMS?CMF to use. Which to choose is dependent on several factors.
* How much custom coding are you going to do?
* How much customization do you need?
* How fine grained control over the system do you want?
Wordpress' strength is it's ease of use, and how you quickly and easily can setup a lot of things. You might be able to get a site like what you want with only a few hours spent. The problem with wordpress however, is when you want to make custom functionality. It doesn't have a strong API like Drupal, and you might have problems changing the output to give you exactly what you want.
Drupal's great strength is it's powerfull API, ability to customize and overwrite anything. In addition to all this, it also has a lot of modules giving you the ability to in many cases build your most/all of your site in a very short time. The problem with Drupal is, that it's not easy to use. You have to spend time learning the system and API before you can take advantage of it. the Drupal AI is also hard to navigate for newcomers, and it takes a while before you learn where the different things are. Drupal is a big machine though, and it can get a bit slow, unless you setup something like Varnish in front of it.
Django is made for rapid development. So once you get into it, which isn't that hard, you can quickly create apps to suite your needs. You have complete control over the urls. The problem with django is that it's not so easy to find the different apps that has been made and figure out which are good. The template system makes it easy to make the markup like you want, but you can't change the functionality of the apps the same way you can with Drupal. One thing to note, is that Pinax doesn't have a 1.0 release yet, while Drupal is on code freeze for it's 7.0 release.
All in all, with all these tools, the biggest challenge is finding out how to use them. If you know wordpress very well and just want to make this one site, you can just use it and be done with it. If however you want to take it further, I would suggest that you use either Django or Drupal. These two has some great development potential. | [DrupalSN](http://drupalsn.com/) is a social network site designed for showing you how to build Drupal sites, and a lot of the [Tutorials](http://drupalsn.com/learn-drupal/drupal-tutorials) on there are focussed on user interaction, so it will be a great resource if you go with Drupal. |

] | Difficult decision. Normally I would say 'definitely Drupal' without hesitation, as Drupal was build as a System for community sites from the beginning, whereas Wordpress still shows its heritage as a blogging solution, at least that's what I hear quite often. But then I'm working with Drupal all the time recently and haven't had a closer look at Wordpress for quite a while.
That said, Drupal has grown into a pretty complex system over the years, so there is quite a learning curve for newcomers. Given that you are already familiar with Wordpress, it *might* be more efficient for you to go with that, provided it can do all that you need.
So I would recommend Drupal, but you should probably get some opinions from people experienced with Wordpress concerning the possibility to turn it into a community site first.

] | I make websites both using Drupal and [Django](http://djangoproject.com) - sometimes with [Pinax](http://pinaxproject.com) (Python). So let me try to set up the differences between Python and PHP, and the different CMS's.
**Python - PHP**
* Pros for Python.
+ You tend to write more readable code making it easier to maintain. This has a big impact if you are going to do a lot of custom coding, now or in the future. However if you aren't going to make that much custom functionality, this doesn't matters.
+ Python and Django is buildt on OO, making it easy to reuse code, and is built on the [DRY](http://en.wikipedia.org/wiki/DRY) princip.
+ I find, that python is more intuitive to program in. In many cases it has a less weird / obscure syntax than PHP.
* Cons for Python.
+ PHP is easier to host. More providers will allow you to run PHP and you can generally find PHP hosters a bit more cheaper than python hosters. If you have your own server, this wont matter.
Generally it's easier to code with python in many regards, but this is something that can be overcome simply by using more time with PHP. Also if you don't know python, that means you will have to invest some time learning it, and the things you can do with python. On the other hand it's a bit more difficult to find cheap hosting for Python projects.
**Django/Pinax vs Drupal vs Wordpress.**
It's always difficult to be able to say, which CMS?CMF to use. Which to choose is dependent on several factors.
* How much custom coding are you going to do?
* How much customization do you need?
* How fine grained control over the system do you want?
Wordpress' strength is it's ease of use, and how you quickly and easily can setup a lot of things. You might be able to get a site like what you want with only a few hours spent. The problem with wordpress however, is when you want to make custom functionality. It doesn't have a strong API like Drupal, and you might have problems changing the output to give you exactly what you want.
Drupal's great strength is it's powerfull API, ability to customize and overwrite anything. In addition to all this, it also has a lot of modules giving you the ability to in many cases build your most/all of your site in a very short time. The problem with Drupal is, that it's not easy to use. You have to spend time learning the system and API before you can take advantage of it. the Drupal AI is also hard to navigate for newcomers, and it takes a while before you learn where the different things are. Drupal is a big machine though, and it can get a bit slow, unless you setup something like Varnish in front of it.
Django is made for rapid development. So once you get into it, which isn't that hard, you can quickly create apps to suite your needs. You have complete control over the urls. The problem with django is that it's not so easy to find the different apps that has been made and figure out which are good. The template system makes it easy to make the markup like you want, but you can't change the functionality of the apps the same way you can with Drupal. One thing to note, is that Pinax doesn't have a 1.0 release yet, while Drupal is on code freeze for it's 7.0 release.
All in all, with all these tools, the biggest challenge is finding out how to use them. If you know wordpress very well and just want to make this one site, you can just use it and be done with it. If however you want to take it further, I would suggest that you use either Django or Drupal. These two has some great development potential. | There's a WordPress extension called [BuddyPress](http://buddypress.org) that'll give you a ready-to-go social network. If it suits you, it may be an easier solution than a Drupal install. If it doesn't suit you, though, I find Drupal more suited to extending in the long run. |
1,513,062 | I am making a community for web-comic artist who will be able to sync their existing website to this site.
However, I am in debate for what CMS I should use: Drupal or Wordpress.
I have heard great things about Drupal, where it is really aimed for Social Networking. I actually got to play a little bit in the back end of Drupal and it seemed quite complicated to me, but I am not going to give up to fully understand how Drupal works.
As for Wordpress, I am very familiar with the Framework. I have the ability to extend it to do what I want, but I am hesitating because I think the framework is not built for communities (I think it may slow down in the future).
I also have a unrelated question as well: Should I go with a Python CMS?
I heard very great things about Python and how much better it is compare to PHP.
Your advice is appreciated. | 2009/10/03 | [

The tie interceptor seems faster than the tie fighter, but also seems to die from less direct hits. The A-wing also seems to be a smaller, quicker version of the X-wing that dies faster.
Is there any documentation or user tests that determine the differences between star fighters in Star Wars Battlefront? | 2015/12/01 | [

67,846 | I am trying to do this for something I've written (4/4 in verse, 6/8 in chorus) but it's difficult to get in and out of smoothly, so I'm wondering how other people have tackled this.

] | "We Can Work It Out" by The Beatles is a pretty famous song with a 4/4 to 6/8 transition (the eighth note stays constant). Despite the time change, it's been an incredibly popular tune.
"All You Need Is Love" is another Beatles song in odd meter. Depending on your counting preference the verse is in 7/4 or alternating bars of 4/4 and 3/4. | Opeth - Windowpane
The first few parts switch between 6/8 and 4/4. They seem to have introduced two solutions for your problem:
1. The pulse of parts is matched (as suggested in other answers),
2. The 4/4 part consists of 6 bars, so if you count beats 1..6 through whole song you should consistently end up on beat 1 when ANY bar begins.
Side note: the off-beat accent in 4/4 seam to ease the transition to me. Again, it stays consistent with 6/8's accents
Here is a link to a drum score for the piece:

] | No examples but some thoughts:
1. Make sure there is a *reason* for the change, and not just because you want to. I mean, there should be something happening in the music and/or the lyrics that helps communicate what you are trying to say that means the verse **must** be 4/4 and the chorus **must** be 6/8. Creating contrast is effective, so if you know why you are creating this metrical contrast, that will help you make it happen effectively.
2. Take your 4/4 tempo and apply it to the 6/8 measures on the dotted quarter note. For example, if you've got 60 quarter notes per minute in 4/4, then you want to have 60 dotted quarter notes per minute at 6/8. Making the tempo change along with the meter change will do a lot to smooth out the meter change.
3. Trying writing a change from 4/4 to 2/4 instead and then see if you feel the need for triplets in the 2/4 section. If the 2/4 section is mostly triplet feel, then you should change it to 6/8 as a compound march (with the tempo adjustment as above). If 2/4 works for the chorus without a lot of triplets, then you really want a 2/4 chorus and not 6/8 at all. | Breaking Benjamin- Psycho

] | No time sig. change is going to be smooth. The piece is going along at whatever pace, the listener is tapping along and suddenly there's a change, which throws it all out of kilter. Even going from 4/4 to 3/4 or 5/4 will sound like there's been a mistake until a few bars have elapsed and the listener settled again.
It's one of the ploys used by some composers to add some unrest into a piece.
Going from 4/4 into 6/8 using the pulse as you suggest can be problematic, as the 'beats' in 4/4 are crotchets, while (in your case) the 6/8 'beats' are quavers. So a tempo change too, as well as a change of feel. Although here, you've addressed it by counting the 4/4 as 8/8.
Another way to go would be thinking of 6/8 as two 'beats', each having three triplets. Still a tempo (and feel) change, but at least another option. | If you want the transition to be smooth, the eighth note needs to stay the same length. I wrote a piece that went from 2/4 to 6/8 in alternating measures. The beats are a little longer in the 6/8 to accommodate the third eighth notes. (If I had combined the rhythm into one measure based on a quarter note, it would have been in 5/4 time but someone I consulted about the piece preferred reading 2/4 then 6/8.) A triplet is not the same thing because it would cause the 8th notes to be a bit smaller to fit all three into one beat. |

67,846 | I am trying to do this for something I've written (4/4 in verse, 6/8 in chorus) but it's difficult to get in and out of smoothly, so I'm wondering how other people have tackled this.
For my song, if you were counting along, the capitalized beats are chord changes, and there is no tempo change in the counts of eighth notes from one section to the next:
Verse (4/4): ONE two three FOUR five six seven eight
Chorus (6/8): ONE two three FOUR five six
Any thoughts on my specific situation or any songs as said that have tackled this type of key change effectively without alienating too many listeners would be appreciated.
Doing time signature changes without losing the listener can be challenging. | 2018/03/12 | [

] | No time sig. change is going to be smooth. The piece is going along at whatever pace, the listener is tapping along and suddenly there's a change, which throws it all out of kilter. Even going from 4/4 to 3/4 or 5/4 will sound like there's been a mistake until a few bars have elapsed and the listener settled again.
It's one of the ploys used by some composers to add some unrest into a piece.
Going from 4/4 into 6/8 using the pulse as you suggest can be problematic, as the 'beats' in 4/4 are crotchets, while (in your case) the 6/8 'beats' are quavers. So a tempo change too, as well as a change of feel. Although here, you've addressed it by counting the 4/4 as 8/8.
Another way to go would be thinking of 6/8 as two 'beats', each having three triplets. Still a tempo (and feel) change, but at least another option. | Breaking Benjamin- Psycho
Verses and choruses are in 6/8 but there's a part after the intro that gets repeated in places that's in 4/4 |

] | Not a soft landing.
A soft landing requires the spacecraft having a [thrust-to-weight ratio](https://en.wikipedia.org/wiki/Thrust-to-weight_ratio) greater than one (otherwise it just falls faster and faster).
Ion engines have a very low thrust to weight ratio, much smaller than one. On the moon, the surface acceleration is 1.625m/s², so the thruster must provide at least 1.625N of force for every kg of spacecraft. Ion engines are several kilograms, while providing less than 1N of thrust, so this is not possible.
[Busek BIT-3](http://www.busek.com/index_htm_files/70010819F.pdf):
* Mass: 1.28kg without gimbal.
* Thrust: up to 0.00125N
* Thrust to weight ratio on the Moon: 0.0006 (best case, assuming the spacecraft is 100% engine by mass)
Just smashing into the surface of the moon at more than a km/s on the other hand does not require slowing down. | Not with an ion engine.
-----------------------
There is nothing fundamentally impossible about putting an engine in a cubesat and making it into a lunar lander. However, this is a very difficult feat, nobody has done anything like it -- cubesats with any significant engines are still uncommon though they [do exist](https://space.stackexchange.com/a/40411/32044).
It should be noted that rocket fuel or high-pressure gas will make launch providers *significantly* less willing to launch your cubesat.
But any engine describable as an "ion engine" is *totally* unsuitable for *landing* on the Moon with anything like current or plausible future technology, and it only gets worse if it's a cubesat.
First, ion engines in general have miniscule amounts of thrust for their weight -- as little as 0.00125 N of thrust for an engine that weighs 1.25 kg (12.26 N) *just for the engine* as stated in the other answer. You need to be able to hover to land softly, and you need to be able to come at least *close* to hovering if you want to land hard-but-less-hard-than-smashing-at-orbital-speed.
Second, for an ion engine you need an external power source, and power sources are *heavy* -- and the amount of power needed goes up rapidly with trying to increase the thrust. And many power sources are not readily able to fit into a cubesat.
You're better off using hypergol. |

That said, this period, known as the New Year holiday period, is one of the few (beside Golden Week and Obon) when most companies/schools will completely shut down for a couple of days (usually 1st to 3rd; with extended periods often including 31st and maybe an additional buffer day to access a weekend. This is especially true for businesses such as banks that tend to be closed on weekends altogether: it is rather likely for them to post a note outside staying the days when they will close around New Year.
Smaller family-run businesses often decide to close across those the days as New Year’s is a family get-together time but some may be interested in making additional profits from those who want to go out with the families on those days.
If you want to know whether a specific shop will open, you have to ask them directly as it’s not really predictable. |

So this is a special celebration, not an all-year uniform. Only those graduating high school (18 years old) take part, and some students will be wearing colours other than red.

If you put a comma after 'singers', it means some singers + Justin + Shakira, isn't it?
So, if you put comma, in fact, you add an ambiguity of separating researchers from those names who are actually researchers. :)

115,291 | I know that in dominant 7th chords the 5th is sometimes omitted but what about if you replace the 5th with a major 6th. Does that make it another chord or is it still a dominant 7 chord? Are there any other options for what chord it could possibly be? | 2021/06/15 | [

] | A 13th chord consists of the notes {1, 3, 5, b7, 9, 11, 13}, which is the entire scale in 3rds (mixolydian if you start on 1, Ionian if you start on 5). We typically do not play all the notes and a common voicing for the 13th chord is {1, 3, b7, 13}. The 13th is the octave of the 6th so I'd say this is a 13th chord. You would want to look at all other ordering of these notes to see if it is another chord. There are multiple chords with identical notes, for example C6 = {C, E, G, A} and A-7 = {A, C, E, G}. In this case I don't see anything obvious that would make this sound like another chord. | So now, you have notes 1,3,6 and ♭7. root C - C E A B♭. It's commonly a way of playing what I call C13. That 6 becomes another 'stacked third' further up the pile. With chords which have a number greater than 7 appended, such as C9, C11, C13, often the 9 and/or 11 is omitted (although the 7 must be retained). The 5 is usually the first to go - particularly on guitar, as there aren't enough strings, or reachable places to play all the notes anyway.
However, you ask if it's still a dominant chord. Of course (assuming the 7 is flat). That ♭7 is what gets it called dominant - although the fact that it's built using the dominant note from the key helps.However, it won't be called 'dominant seventh'. It isn't a seventh chord any more, there's a 13 in there. So it's called **dominant thirteenth**. |

The 5th is a relatively inactive filler which is why, as you say, it is considered optional. A 6th will probably be heard as a 13th (octave shifts don't change the numbering). So we end up with a dominant 13th chord.
If the 6th/13th is just in the melody, we might still label the chord as 'G7'. If it's considered an integral part of the harmony we would call it 'G13'. |

* X must see the whole space S including T
