13,454,202 | I have added a chat capability to a site using jquery and PHP and it seems to generally work well, but I am worried about scalability. I wonder if anyone has some advice. The key area for me I think is efficiently managing awareness of who is onine.
detail:
I haven't implemented long-polling (yet) and I'm worried about the raw number of long-running processes in PHP (Apache) getting out of control.
My code runs a periodic jquery ajax poll (4secs), that first updates the db to say I am active and sets a timestamp.
Then there is a routine that checks the timestamp for all active users and sets those outside (10mins) to inactive.
This is fairly normal from my research so far. However, I am concenred that if I allow every active user to check every other active user and then everyone update the db to kick off inactive users, then I will get duplicated effort, record locks and unnecessary server load.
So I have implemented an idea of the role of a 'sweeper'. This is just one of the online users, who inherits the role of the person doing the cleanup. Everyone else just checks whether there is a 'sweeper' in existence (DB read) and carries on. If there is no sweeper when they check, they make themselves sweeper (DB write for their own record). If there are more than one, make yourself 'non-sweeper', sleep for a random period and check again.
My theory is that this way there is only one user regularly writing updates to several records on the relevant table and everyone else is either reading or just writing to their own record.
So it works OK, but the problem possibly is that the process requires a few DB reads and may actually be less efficient than just letting everyone do the cleanup as with other research as I mentioned.
I have had over 100 concurrent users running OK so far, but the client wants to scale up to several 100's, even over 1,000 and I have no idea of knowing at this stage whether this idea is good or not.
Does anyone know whether this is a good approach or not, whether it is scalable to hundreds of active users, or whether you can recommend a different approach?
AS an aside, long polling / comet for the actual chat messages seems simple and I have found a good resource for the code, but there are several blog comments that suggest it's dangerous with PHP and apache specifically. active threads etc. Impact minimsed with usleep and session\_write\_close.
Again does anyone have any practical experience of a PHP long polling set up for hundreds of active users, maybe you can put my mind at ease ! Do I really ahve to look to migrate this to node.js (no experience) ?
Thank you in advance

] | Long polling is indeed pretty disastrous for PHP. PHP is always runs with limited concurrent processes, and it will scale great as long as you optimize for handling each request as quickly as possible.
Long polling and similar solutions will quickly fill up your pipe.
It could be argued that PHP is simply not the right technology for this type of stuff, with the current tools out there. If you insist on using PHP you could try [ReactPHP](https://github.com/react-php/react), which is a framework for PHP quite similar to how NodeJS is built. The implication with React is also that it's expected to run as a separate deamon, and not within a webserver such as apache. I have no experience on the stability of this, and how well it scales, so you will have to do the testing yourself.
NodeJS is not hard to get into, if you know javascript well. NodeJS + [socket.io](http://socket.io/) make it really easy to write the chat-server and client with websockets. This would be my recommendations. When I started with this is, I had something nice up and running within several hours. | My advice would be to do this with [**meteor**](http://meteor.com/) framework, which should be pretty trivial to do, even if you are not an expert, and then simply load such chat into your PHP website via iframe.
It will be scalable, won't consume much resources, and it will get only better in the future, I presume.
And it sure beats both PHP comet solutions and jquery & ajax timeout based calls to server.
I even believe you could find on github more or less a completed solution that just requires tweaking.
But of course, **do read the [docs](http://docs.meteor.com/)** before you implement it.
If you worry about security issues, read [**security with meteor**](http://britto.co/blog/security_with_meteor) |

This way the hosted service handles the scaling of the realtime infrastructure for you and lets you concentrate on building your application functionality.
This way you only need to handle the chat message requests - sanitize/verify the content - and then push the information through Pusher to the 1000's of connected clients.

9,982 | Working in web-development, I face a common situation when clients want to use 3rd party software as a starting point of the project. That could be a CMS, an e-commerce site, or something else. Motivation is usually budget-driven; it seems to the client that having a web site built atop of some off-the-shelf product will cut costs. It is not always true. For example:
* The client (often a non-technical person) was told that it's super-easy to build a 3-page website using a famous CMS. However, nobody knows what it takes to build a 100-page website, with a blog feature and 3 levels of paid membership.
* The team doesn't know the CMS before the project starts, so adding requested features become a hard task, and the existing CMS code often stands in the way of effective development.
* It also may turn out that there's no decent documentation. The team would create similar features faster *without* that CMS, but the client still insists on using it.
* Adding custom design to the CMS-based site may cause trouble for HTML developers, requiring development of non-trivial code (for example, an obscure menu system).
* It may turn out that the CMS is not compatible with the hosting that was usually used for deployment, the CMS has internal flaws preventing scalability in production, or that the solution requires enormous hardware setup to operate properly under load.
That leads to questions I'd like to ask:
* How can we convince a client that his solution should not require a custom CMS, or that it may take *longer* to develop a custom solution using pre-existing code? Clients usually has arguments like 'the biggest sites on the Internet are using this CMS,' but we don't really know how much effort was put but those biggest sites to run the CMS properly.
* How to include 3rd party (or pre-existing) code into our initial estimation and risk-management calculations? Any numbers and techniques are welcome. | 2013/09/30 | [

] | TL;DR
-----
You aren't really asking a risk-management question. At heart, the question is really about how to estimate projects where you have no baseline values. A common solution is to use a pilot project to generate planning values as inputs to a full-scale project.
Ability to Estimate
-------------------
Your project's ability to estimate accurately (or at all) depends a great deal on the team's experience with a specific knowledge domain. If you have zero experience with a given technology or project, then your project schedule is a black box; there is no way to estimate it other than guesswork.
Even assuming some knowledge, all projects have a [cone of uncertainty](http://en.wikipedia.org/wiki/Cone_of_Uncertainty). Generally, you will plot a preliminary schedule based on some planning values, often adjusted by a [fudge factor](http://en.wikipedia.org/wiki/Fudge_factor) representing the amount of uncertainty the team has about the project. For example, inexperienced teams might multiply their initial productivity values (e.g. velocity) by 0.6, or pad their schedule by multiplying time estimates by 1.4.
The actual value of the fudge factor is less important than the clear knowledge that it *is* an adjustment to the planning values. Remember: an estimate is an *informed opinion*, not an iron-clad guarantee.
Pilot Projects
--------------
If your project involves skills outside the team's current area of expertise, or if there's a need to perform some tasks in order to calibrate the schedule for a larger project, then you need a [pilot project](http://en.wikipedia.org/wiki/Pilot_experiment).
For example, rather than trying to estimate a 100-page website with a tool-chain no one has experience with, you might plan a pilot project for a 5-page web site. The important deliverables from a pilot project like this aren't actually the web pages; the real deliverables are experience with the proposed solution and better input values for the larger project.
For instance, you might do your 5-page study in two weeks, but discover that the solution won't scale the way you need it to. Or, you might find that initial setup takes a week, and developers can average a page a day thereafter.
Whatever the results, you use the data from the pilot project along with a new set of more-informed fudge factors to generate the schedule or estimate for the larger project. This may or may not be linear: a 100-page web project isn't necessarily 20 times the complexity of a 5-page project. However, your cone of uncertainty should be smaller after a pilot study, and your estimates will be much more likely to fall within the boundaries of acceptable variance. | Question #1: this is a business case. To convince a customer of anything, you need to build an argument. Develop a case that exhibits several alternatives from which the customer can choose, the benefits/costs/risks of each alternative, and your recommendation. Your recommendation needs to be supported and substantiated with industry standards and facts that you find in your research, not just your opinion likely biased by your pursuit of profit. Your entire presentation needs to be supported by the relationship you have developed with your customer. You would not be just a vendor pitching your wares but a trusted adviser.
Question #2: This is a risk management question. And you would apply normal risk management techniques. There are few projects out there that are not dependent upon something external that could adversely or favorably impact your schedule and budget. So this is normal; welcome to project management 101.
Research what you can about the external dependency, e.g., reputation in the market place, history of being late or on time, references, etc. What you can't learn, you need to draft an appropriate assumption (a source of risk). You load your schedule with the external milestones based on that assumption so you can communicate clearly how your performance would be impacted if those assumptions do not bear fruit. You can load schedule reserves to accommodate something coming in late and, most of all, you communicate clearly to your customer where you have dependencies, the risks you and your customer must accept, and any updates to what you are observing.
You can only control what you can control. Most of the very random variables that affect our performance, both favorably and unfavorably, are way out of our control, which is very counter intuitive to all the business type A's managing projects, but such is life. All you can do is watch for them, plan for them (risk management), communicate what you are observing in a timely way, and accept the fact this is all very normal. |

Most fixed-location time series data will have a finer temporal resolution, but will be lower spatial resolution. You'll sometimes see this called a "sensor net" if it follows a fixed grid, but that term's also used in other fields, so it's difficult to find useful results using most search engines.
For urban temp data, you might want to see [Muller et.al's 'Sensors and the Cirty'](http://www.academia.edu/2455213/Sensors_and_The_City_A_Review_of_Urban_Meteorological_Networks) which catalogs 'Urban Meteorological Networks'. It'll at least give you the names of sensor networks to look for data from.
There's a lot of spatio-temporal satelite data, but the ones with higher resolution (eg, [Landsat](https://landsat.usgs.gov/LSDP.php)) take days before they come back to give another pass (16 days for Landsat 7 & 8). The geostationary satellites such as [GOES](http://goes.gsfc.nasa.gov/) tend to have fixed telescopes, which likely won't give you the resolution needed (the 'high resolution' images are ~64km^2/pixel).
**update** : I was wrong about the satellites -- because I didn't consider that you might get data from more than one satellite flying the same instrument. [MODIS](http://modis.gsfc.nasa.gov/) is flown on both Aqua and Terra, has 250m resolution, and they each scan the whole earth every 1.2 days. Due to how they scan, there's also overlap in the passes, so stuff not directly below the satellite track can be imaged twice (with distortion). |

3,691 | I am an Italian student, and I'm looking for a particular dataset.
I'm interested in a model for spatial regression, with time-varying data. I'm looking for data with coordinates, measured in different moments for each point. Where can I find them?
I don't have a specific request for the dataset. I need to try a statistical model. This model works with data spatially distributed (so every datum is located with his coordinates), and for every point (located by the coordinates) I need more measurements, at different times.
I leave an example. I'm measuring the temperature at different points of my city during the day. I'm interested in two points: the center (coordinates...) and near the river (coordinates...). Data are measured hourly. So I have (starting from 8:00):
Center: 25C, 27C, ...
River: 22C, 24C, ... | 2014/09/23 | [

 | You have two basic options for data -- either time series data from a known location (or multiple locations), or reocurring satelite imagery.
Most fixed-location time series data will have a finer temporal resolution, but will be lower spatial resolution. You'll sometimes see this called a "sensor net" if it follows a fixed grid, but that term's also used in other fields, so it's difficult to find useful results using most search engines.
For urban temp data, you might want to see [Muller et.al's 'Sensors and the Cirty'](http://www.academia.edu/2455213/Sensors_and_The_City_A_Review_of_Urban_Meteorological_Networks) which catalogs 'Urban Meteorological Networks'. It'll at least give you the names of sensor networks to look for data from.
There's a lot of spatio-temporal satelite data, but the ones with higher resolution (eg, [Landsat](https://landsat.usgs.gov/LSDP.php)) take days before they come back to give another pass (16 days for Landsat 7 & 8). The geostationary satellites such as [GOES](http://goes.gsfc.nasa.gov/) tend to have fixed telescopes, which likely won't give you the resolution needed (the 'high resolution' images are ~64km^2/pixel).
**update** : I was wrong about the satellites -- because I didn't consider that you might get data from more than one satellite flying the same instrument. [MODIS](http://modis.gsfc.nasa.gov/) is flown on both Aqua and Terra, has 250m resolution, and they each scan the whole earth every 1.2 days. Due to how they scan, there's also overlap in the passes, so stuff not directly below the satellite track can be imaged twice (with distortion). |

] | To answer the general question: You can be a interdisciplinary researcher by getting multiple degrees in different fields, getting a single interdisciplinary degree, or by getting a degree in one field and, over the course of your career, working your way into another.
Most academic jobs are hired by departments, and the wide majority of departments are single-disiplinary, though interdisciplinary programs are fashionable right now.
To be a marketable researcher in a given discipline, you would generally need at least a phd in that discipline, possibly a interdisciplinary phd that centrally involved it (marketability depends a lot on the specific interdisciplinary program, but in general, these will be less appealing than an phd in the actual discipline), or, in very rare cases, a a phd in a different discipline but VERY extensive research in that discipline. When it comes to the latter, things are probably more flexible in the humanities than in the sciences, and often only in one direction (ex. there are philosophy phds in rhetoric departments, but not rhetoric phds in philosophy departments). In general, you need to be able to teach introductory courses in that discipline as well as in your particular area.
Some universities do have particular interdisciplinary departments or other interdisciplinary lines, but these are in established interdisciplinary subjects—cognitive science, peace studies, asian cultures, environmental studies...
There are also "cluster hires," where universities look to give a researcher appointments in multiple departments for work on topics like diaspora studies and agroecology that are appealing to administrators but too small to support entire departments. Cluster hires are rare and are not something you can plan a career around.
There are no lines for unspecified "interdisciplinary" researchers. You need to be able to market yourself under a specific discipline or under an established interdisciplinary program. In general, the latter will be harder. | There are two groups of researchers relevant to your question. The inter-disciplinary ones, and the multi-disciplinary ones.
I know one or two hundred inter-disciplinary researchers. With a couple of exceptions (so now we're down to a tiny tiny proportion of all researchers), they nevertheless all have a single specialism: in each case, it's a specialism that spans more than one traditional topic. Typically, they did one (or occasionally two) Masters' degree(s) in fields different to their first degree, and then did an inter-disciplinary PhD.
Only the exceptions are multi-disciplinary. We became that through many years of working across different fields. We're not specialists in all of those fields. But we know enough to be able to work in teams that consist of specialists from any combination of them. None of us planned it this way - it just emerged as a consequence of our (lack of) career path.
Many fields see the multi-disciplinary researcher as something of a luxury. In the first instance, most principal investigators and other research leaders seem to prefer single-discipline experts. An enlightened few see the benefits of creating the best team, rather than just selecting the best individuals; and for inter-disciplinary work, a multi-disciplinary researcher can be the catalyst that enhances the performance of the rest of the team, as well as doing research in their own right. |

There are no lines for unspecified "interdisciplinary" researchers. You need to be able to market yourself under a specific discipline or under an established interdisciplinary program. In general, the latter will be harder. | This is a tough question. I will set aside the issues of whether it is "interdisciplinary," "multidisciplinary," "cross-disciplinary" or any of a number of other terms that some people get very emotional about. I have heard some people give definitions of all of these terms that overlap, and my humanities friends definitely have strong opinions about them, while my science friends often just can't see the point of using any of the terms or keep them straight.
This sort of work is intrinsically hard to support in academic settings. Many departments actively punish people who do inter-, cross-, multi-disciplinary work in promotion decisions, by either downgrading the importance of that work in the promotion decision or completely removing it from the calculation; effectively saying "focus on what **we** do, here." Most interdisciplinary workers I know believe that they are behind the curve on promotions and advancement.
So programs that are truly interdisciplinary are rare. (There are some great exceptions, "Energy Studies" was mentioned in comments, and "Neuroethics" exists at my school -- there are others. Basically once a set of topics get pushed together often enough they can form their own field or discipline.)
You seem to be interested in the student or taking-classes side of this, so I will focus on that.
First, look at the topics you are trying to combine and see if they exist in that combination. For instance, you mentioned neural nets and machine learning which 20+ years ago were semi-independent fields (the former often in computer science departments and the latter often in engineering), and are now the inter-disciplinary "artificial intelligence" (at least at some schools; your local history may vary). Likewise, instrumentation and control engineering, embedded systems, and robotics will all include strong signal processing components. So signal processing may be covered in the others.
So start by picking as a central field one that combines the maximum number of interests you have.
Then, pick your second majors and minors carefully to fill in more, if you can. You may end up getting multiple degrees along the way, all in different fields. That is what happened to me, I have a BA/BS, three masters degrees, and a PhD; all in different fields, and all important to the work I do these days.
Just as importantly as degrees and classes are projects. Often part of education is doing projects and you usually get to pick topics that interest you. Pick things that combine topics you want to combine. To do projects you will need a lot of self-study, a skill you will need a lot of if you are serious about being multi/inter/cross-disciplinary in your working life.
**But** a lot of inter/cross/multi-disciplinary work only comes into existence once you get to work. So expect to keep learning well past the degree phase. That may be where you get the most of the stuff that makes your work interdisciplinary. |

3,816,537 | We have a series of nightly batch jobs running as Windows Scheduled Tasks. Their numbers have grown to a point that they are beginning to step on each other since there are no dependencies between the batch files, just start times. We are considering the use of PowerShell to write scripts to control the nightly cycle...can anyone confirm we are making a sound choice.

] | Powershell would be a reasonable place to start. You could dispense with the Windows scheduler altogether and run a Powershell script as a service (using something like SRVANY.EXE). There may even be a "native" way of getting Powershell to run as a service.
Your job definitions, dependencies, failure actions, Etc., could be stored in XML format, which can easily be read by Powershell.
The only area I can see being an issue is the required accuracy of scheduling, i.e.: does it have to be to the second?
PowerShell has some nifty job execution cmdlets, see start-job, get-job and receive-job. | I don't think PowerShell will help much with your specific problem of scheduling and dependency management. But it may be a good idea for the actual jobs.
For scheduling, maybe you should look at a free build management tool like [CruiseControl](http://cruisecontrol.sourceforge.net/) or [Luntbuild](http://luntbuild.javaforge.com/). Such tools are built to handling scheduling and dependency management for many jobs. |
40,044 | To my mind, the ο ων of Exodus 3 would fit better here than ο ζων, even more naturally, with the words "I am the First and the Last," ο ων of course being the translation of the Tetragrammaton in the Greek Old Testament. And I can see how "alive" (ζων) could possibly become a corruption of ων in the immediate context: "I am the First and the Last, and the Living One [ο ζων]. And I was dead, but behold, I live (ζων ειμι) forever..." To me, "I am the First and the Last, and He who is [יהוה/ο ων]. And was dead, but behold, I live forever..." After all, ο ζων would amount to a divine title—"the Living One," since you wouldn't say, "I am *he who is* alive" if you were simply going to say, "I am alive" (not that "the First and the Last" is not already the name of God used here of the Son).

] | Metzger's [*Textual Commentary on the New Testament*](https://rads.stackoverflow.com/amzn/click/com/1598561642) does not discuss any significant textual variant here. According to Tischendorff's apparatus, there is a redaction of the Codex Siniaticus that omits και from the phrase και ο ζων, but nothing else.
The oldest complete Patristic commentary on Revelation was written by [Andrew of Caesarea](https://en.wikipedia.org/wiki/Andreas_of_Caesarea) (533-637), and has been [translated by Dr. Eugenia Constantinou](http://www.tpkatsa.com/papers/Revelation_Andrew.pdf). Andrew here writes:
>
> *And when I saw him I fell down at his feet as dead. And he laid his right hand upon me saying, "Do not be afraid. I am the first and the last and the living one. And I became dead, and behold I am living unto the ages of ages. Amen.*
>
>
> Christ revived the Apostle [John] himself who had died through the weakness of human nature like Joshua son of Nun (Joshua 5:14) and Daniel (Daniel 8:17, 10:9-12) by saying to him, "Do not fear, for I have not come near to kill you, since I am beginningless and endless, having become dead for your sakes."

Oecumenius of Isauria, who slightly predates Andrew, wrote:
>
> The holy John would not have been strong enough to survive his astonishment had the saving right hand of the Son of God not touched him, which by the mere touch had accomplished so many wonderful things. And he said to me, “I am the first and the last,” which is as though he had said, “I am he who for the salvation of you all sojourned among you in the flesh at the end of times, even though I am the First and the firstborn of all creation. How is it possible that anything evil transpire from my appearance? For if I who am living and am the wellspring of life became dead for you, and trampled death underfoot and lived again, how is it possible that you who are living become dead on account of me and my appearance? And if ‘I have the keys of death and of hades,’ so that I make dead and make alive those whom I wish, and that I will bring down to hades and bring up again, as it is written concerning me, and that, as the prophet says, escape from death belongs to me (Psalm 68:20), I would not have sent my own worshipers and disciples to an untimely death.”

One other Church Father who comments on Revelation 1:18 is [Cyprian of Carthage](https://en.wikipedia.org/wiki/Cyprian) (210-258). In his Latin translation of the verse in *Ad Quirinium*, II.26, he also reads ο ζων here.

Eastern Orthodox writers are usually particularly sensitive to being faithful to patristic interpretations of Scripture and highlighting differences of opinion between the Fathers. [Lawrence Farley](https://www.ancientfaith.com/contributors/lawrence_farley)'s commentary here explains:
>
> He tells John, “Do not be afraid,” and in this He tells all of John’s churches not to fear. They need not fear death, martyrdom, or anything in all the world. Why? Because Christ has overcome the world, trampling down death by death. He became dead, but now He is alive to ages of ages. As such, He is the first and the last, sovereign over all (compare God as the Alpha and Omega in 1:8) and the Living One, the source of all life. He had authority over death and Hadesby His Resurrection. Death cannot now separate us from Him, for He is Lord of both the living and the dead.1

Russian Orthdox Archbishop [Averky Taushev](https://www.google.com/search?q=averky%20taushev) (1906-1976) also wrote a Patristic commentary on Revelation. Here he comments:
>
> From these words, St John had to understand that the One Who appeared was none other than the Lord Jesus Christ, and that his appearance could not be fatal for the Apostle, but on the contrary, would be life giving. To have the keys to something signified among the Jews to receive authority over something. Thus, “the keys of hell and of death” signify authority over the death of the body and the soul.2

Thus, I do not believe there is any credible Patristic source that ever read anything other than ο ζων in the text.

--- | First, I could find no evidence of any variation in the text of ancient sources at Rev 1:18. (I can understand the reason for the excellent, ingenious and penetrating question.)
However, I find much precedent for text as it is BUT implying that YHWH is implied. I note that:
* That Jesus takes the title, "First and Last" is a direct allusion to the exclusive title of YHWH in Isa 41:4, 44:6
* In John's writings, Jesus is often depicted as the source of life, 1 John 5:11, 12 (Greek zoe). See also John 15:1-5.
* In other places Jesus is described explicitly as the source of life such as John 6:35-51 (bread of life); John 11:25 (resurrection and life); John 14:6 (way truth and life). Again, in each case, the Greek word is zoe.
There are numerous other places where NT writers use OT titles of YHWH as titles of Jesus. God (Deut 4:35, 6:4, 32:39 vs Matt 1:22, 23; John 1:1, 18 20:28), Creator (Isa 44:24, 45:18 vs John 1:3, Col 1:16, 17), Saviour (Isa 43:3, 11, 45:17, 21 vs Matt 1:21; Acts 4:12; 2 Tim 1:10, Tit 1:4, 2:13, 3:6; 2 Pet 1:1, 11), First and Last (as quoted above), etc. |

] | No symbol for 'why ?', I'd say for the following reason.
Isn't logic's concern with the structure of propositions (statements, sentences) and predicates, and the relations of contradiction, implication and independence between them, also the valid and fallacious forms of argument (valid in the case e.g. of modus ponens, fallacious in that of affirming the consequent ? 'Why?' is usually an epistemological question rather than a logical one.
In modus ponens, for example :
If p then q
p\_\_\_\_\_\_\_\_\_\_
q
we do not look to logic to explain e.g. 'why p ?'. We look to it to identify p's role in valid or invalid arguments such as the above schema.
See further Michael Gabbay, 'Logic with Added Reasoning', Ontarioo, 2002, Preface & ch. 1.
My indication of logic's concerns at the start is not offered as a full refinement but only as a broad pointer. Refinement can be found in texts such as Gabbay's or Patrick Shaw's 'Logic and its Limits', London, 1981, where in turn more sophisticated texts are listed in the bibliographies.
You also asked about 'what is'. Your example suggests you are thinking of disjunction : 'either it's X or it's Y'. Symbolically : 'V' or 'v' : 'X v Y'. The name of the symbol is 'vel'.
'Or' is ambiguous in logic : there's the inclusive or the exclusive 'or'. So, for example, 'Either X or Y (but not both)'. This is the exclusive use. But 'Either X or Y (or both)' illustrates the inclusive use : it includes both alternatives as possibly being the case. 'Either it's red or it's antique' - inclusive (it could be both). 'Either it's a circle or it's a square' - exclusive (it is one or the other but not both). Your example seems to employ the exclusive 'or' - either it is a car-crash or it is a kid oopping a balloon but not both.
On the inclusive and exclusive uses of 'or' ('V') see Patrick Shaw, 'Logic and its Limits', London, 1981 : 49-51. | No. Formal logics deal with concrete propositions, not speculative discussions.

After two accepted edits [(1)](https://webapps.stackexchange.com/posts/33153/revisions), [(2)](https://webapps.stackexchange.com/posts/30019/revisions), it seems that my account has been disallowed for further suggested edits. I don't have links for rejected ones, however.
I realize that presumably, someone has decided the edits were too minor or whatsoever. Indeed, I was primarily fixing grammar, layout, or other things making the Q&A more readable.
Nevertheless, [it's a common sense](https://meta.stackexchange.com/questions/116509/an-alert-to-serial-minor-edits) on SE that even minor edits are still useful, if they indeed provide with meaningful value and [aren't massive](https://meta.stackexchange.com/questions/129487/do-rapid-serial-edits-get-auto-reversed). So *any constructive edits*, even fixing typos or formatting, should be encouraged as they (1) improve readability and (2) searchability on search engines, which in turn attracts new visitors and provide with value for existing ones.

Is it true that WA@SE rules are somehow different?
I'm not an active user here, but I was thinking that could be a positive contribution to a community.
Am I wrong?

**Update**
*This is not an an appeal*. What's done is done.
*"Something else to be improved in the posts"*. Look at the edits that have been kindly accepted (I don't find the links to rejected ones). Is there anything else to improve there?
Moreover, minor edits is a kind of "dirty work". They consume a lot of moderator's time which they can rather spend on something else. Doing it by non-moderators (or users with rep under 2000) is a profit for the site, see links above for why.
*"Pursuing rep"*. Please don't accuse me pursuing +2 reputation for these edits; it's much easier time investment to submit five good Q/A to gain rep.
*Actual Question*. My goal is to figure out whether the WebApp@SE community needs **this very type of contribution**. If it doesn't (*for whatever reasons or whoever is right or wrong*), this is the only thing I really want to know. | 2012/11/18 | [

I approved the first couple as they seemed OK, but then as more edits of the same kind came in I realised that **all** you had done is gone through looking for posts that required this edit.
While this kind of edit can improve the post, it's very rarely the only change that needs making. By concentrating on this one aspect you are ignoring the rest of the post and not making other edits that would improve it overall.
The other danger is that by making lots of minor edits like this you flood the homepage with old, often answered, questions.
The ban on suggesting edits is only temporary, so when it's lifted you can go back to helping to improve the site. Just take your time and look at the big picture. | Guidelines on what to suggest for edits are the same for across the network. It just depends on how much the reviewers let you get away with or don't pay attention to the other issues left over with a post.
When you change just the formatting, or only add superficial styles, and there remains more that can be done (spelling, grammar, spacing) then the weight of those left around counts against the edit.
Have enough [suggested edits knocked back](https://meta.stackexchange.com/questions/76251/how-do-suggested-edits-work "definitions of abuse depend on abuse") and you'll have to wait a week to do it again.

] | Assuming you've actually **measured** Vgs **at the MOSFET pins** (it gets only about 90% of the drive voltage, and the drive voltage is heavily loaded by the LED), then one would tend to conclude that the MOSFET is not actually a genuine part of the type indicated. The certainty would increase to near 100% if the MOSFET was sourced on a platform that hosts bad actors.
The dissipation should be no more than about 0.7W which **will** get hot without a heatsink, but not excessively so (150°C is excessive). If your traces or wires going to the MOSFET are thin you may also be getting heating from those sources. Tja is 62°C/W so the rise should be the order of 40-45°C. Rds(on) increases with increasing junction temperature, maybe 50%. But not 125°C rise worth. | The mosfet you picked should be able to handle 15A with no heatsink without any issues.
The datasheet says that at Vgs=10V the Rdson should be 1.4mR. P = I2\*R = 15\*15\*0.0014 = 0.315W. At 20A that would be 0.56W
The datasheet also says that Junction-To-Ambient thermal resistance is 62degC/W. So at 560mW that gives 35degC temperature rise over ambient.
Did you measure the Vds over the MOSFET? At 15A and 1.4mR it should be only 21mV. If you see anything higher, the part is bogus.
btw in your schematics you are running the load current through a jumper (J5). A standard jumper will have a resistance of 20-50mR. So at 15A that will dissipate at least 4.5W - that should be enough to melt the jumper. |

If I understood correctly, this is being used to control a 3D printer heated bed.
Its not clear from your post what "full power" means, but if it is really on a 3D printer application, I suspect its not on all the time but rather in PWM due to PID control of the bed temperature.
Considering that the gate capacitance of that FET and that the gate resistor is relatively high (1k Ohm), it could be that a lot of the heat you are generating is from turning it on and off (High RdsOn periods).
If that is the case, you can try to lower the gate resistor a bit and/or find a part with lower gate capacitance. | The mosfet you picked should be able to handle 15A with no heatsink without any issues.

] | Photons don't move at all. What changes is the probability to find an excited photon state at a spacetime point. If gravity were just another field, then the existence of a photon state in one spacetime point would create excited graviton states around it. This is the usual formulation of quantum field theory on a preordained background.
Unfortunately gravity doesn't quantize this way. Gravity is the distortion of the background metric itself, rather than an excitation of a field that lives on the background metric.
I do not believe that string theory has achieved the required manifest background independence, yet, but I am willing to let a string theorist correct me on this. In absence of this string theory can still use a perturbative approach to the problem that one can hope gives the correct results without requiring a background independent mathematical formulation.
Having said that, the coupling between single photons and gravitons is incredibly weak until we get to extremely high energies. If the Planck scale exists (a big if), then we will have basically no way of producing photon energies high enough to see the production of high energy gravitons in our accelerator facilities anytime soon. At this point the question if gravitons exist is therefor experimentally not tractable, leaving little else but guesswork for theoreticians. | Because in my view we have a coupled photon-graviton.
The Photon – Graviton pair (coupled) has the same speed and frequency, and the photon energy divided by the graviton energy is the electromagnetic energy divided by the gravitational energy, the electromagnetic force divided by the gravitational force. |

With [electromagnetic couplings](http://hyperphysics.phy-astr.gsu.edu/hbase/forces/funfor.html) at the vertices, this diagram when calculated gives a very low probability due to the 1/137 value of the coupling constant Only at high energies due to the functional form under the integrals can a measurable probability be predicted.
Suppose that one has quantized gravity , and the hypothetical graviton exists. The corresponding coupling is 6\*10^-39 . So the equivalent gravitational interaction diagram would be about 10^35 times weaker than the corresponding electromagnetic one, just at each vertex. Thus one is talking of infinitessimally small gravitational effects, not attainable in our laboratories. In cosmological models such energies can be hypothesized and in the primordial soup of the [Big Bang](https://en.wikipedia.org/wiki/Big_Bang) it will be part of the gravitational interactions that bounds the universe but these are theoretical propositions. | Because in my view we have a coupled photon-graviton.

blow the drive away.

click start, right click my computer, click manage, click disk manager, click your usb drive, delete the partitions, create a new partition using 100% of the space.
3. Keep it from happening again.
Kinda vague on my instructions here, but basically you right click that new volume on your usb disk, properties of it and there should be a tab that is unique to USB removable drives. That tab has some options to basically "make this volume run faster- but there will be he11 to pay for yanking it out" - you are going to click the one that says "Run a little slower but be prepared to be randomly ejected from the computer".

7,655,088 | i'm creating a shopping website using c# and asp.net and i want to use MVP pattern inside of three tier architecture, specifically in the presentation layer.
the reason i'm doing this is because i've been read and heard that MVP is a UI pattern however i came across a design problem! if MVP is a UI pattern and it should be used inside of presentaion layer and so it's not a representation of a database table then what exactly would make up my model??
i suspect that the data from the business layer is making up my model but when i think about it the only thing that is coming to my presentation layer from my business layer is the requested data table. so what would make up the model?
for an example consider the amazon.com as the shopping site that i'm trying to create. | 2011/10/04 | [

] | I will probably be in the minority with this, but whenever I talk about the usage of any of the MV\* architectural patterns, I often do not apply it at a system wide level, but on a individual component level.
For example, Java Swing UI elements are built using MVC principles. That is to say that MVC is being applied on a component level in the presentation layer.
For your case (using MVP only in well-defined presentation layer), your MVP model could be a shell that interfaces with your business logic layer. Or it could be domain POCOs, that get instantiated by repositories. | The Data Table is your model. Or the way I prefer to think about it is the *entire* business layer is the model, and the UI contains the View and Presenter. |
1 | Most American crosswords use rotational (or "radial") symmetry so that squares directly opposite each other (through the center) are identical.
In the Times, I've only seen this **not** be the case when the layout was directly linked to the theme. Is that one of the "rules" you can count on, or are there (modern, Will Shortz era) examples of cases where you can't assume that non-radial symmetry will be somehow related to the theme?

10,727,893 | I'm writing a weather app that learns what you wear based on current conditions/temperatures to tell you what you should wear outside. I'm collecting some simple data and storing it on the device. I'm collecting:
* Date/time
* Weather temperature
* Weather conditions
* 6 int fields:
+ Head
+ Chest
+ Hands
+ Legs
+ Feet
+ Accessory
I will query the data based on the current temperature/condition to get an average of the values in the 6 int fields to predict what the user usually wears.
I'm keeping this on iPhone only. What would be a good, client-side, data storage method for this? The queries aren't too intense, but I need to query on type and range.

] | I would recommend using Core Data or SQLite. Your right, this is not a lot of data being store. What if that Application is a success, and you want to expand your concept?
For example:
(1) You want to store more data
(2) Maybe sync data to a server
(3) Changing the type of data your storing
You even mention QUERY in your question, to me that is your answer right there. This would all be much easier with Core Data. There will be a learning curve, but learning this framework will be beneficial with future projects.
Good luck with your project. | A previous poster recommends Core Data over SQLite. Although they're right to suggest one of those two alternatives, if you are already familiar with MySQL and you're looking for a get-in/get-out app, I'd recommend you go with SQLite.
Core Data is an excellent framework, but there is a learning curve that may not be worthwhile considering your specifications and your previous experience. SQLite is simple, fast, and client side. Moreover, your queries won't look any different from MySQL.
Other posters mention serializing over NSUserDefaults or NSKeyedArchiver. While they do make serialization simple, you'll end up rolling your own query code using NSPredicate. It's not so difficult, but again, it may be a new technology that, while worthwhile, is better saved for another time. More of a concern is that they won't scale well if your app does start using a lot of data quickly.
Regarding scale more generally, ff your app does become wildly successful, worry about it then. You can always refactor and scale when it's necessary. |

] | After research I have found the cause and the solution to my problem.
**Cause**
SharePoint update removed the ability of calculated fields to be set us markups and is explained in [Handling HTML markup in SharePoint calculated fields](https://support.microsoft.com/en-gb/help/4032106/handling-html-markup-in-sharepoint-calculated-fields).
**Solution**
I have found a solution with JSLink. After opening link above, there are some examples using JSLink. With a bit of play-around, I managed to achieve having the calculated field as a hyperlink. The steps are simple.
1. Create a js file with code - in my case I create a hyperlink which posts to another list with values from current item.
2. Copy link location of js file.
3. Reference js file on web part on view, under section Miscellaneous.
4. Voila!
Note: in the script, the field name must be the internal field name, that slowed me down quite a bit. to get the internal field name, open list settings, hover over desired field and on the bottom left of your browser you get the internal field name (Field=Internal field name here).
JSExample can be found [here](https://code.msdn.microsoft.com/office/Client-side-rendering-JS-2ed3538a).
Another helpful read [here](https://www.codeproject.com/Articles/620110/SharePoint-Client-Side-Rendering-List-Views). | As mentioned as a follow-up by the original poster, as of June 2017, you can't do this anymore.
For SharePoint Online, the alternatives are to embed some JavaScript on the page or to use the new [SharePoint PnP Fx Extensions](https://github.com/SharePoint/sp-dev-fx-extensions). If you have your own SharePoint Server, you can use the API [i.e. through PowerShell] to modify the Web object's CustomMarkupInCalculatedFieldDisabled property.
I needed a little bit more robust solution, so I created a SharePoint Extension to do this. You can [view it from GitHub](https://github.com/JNadrowski/js-field-url-link). The instructions should be able to get you up and running in a couple minutes. I find it much easier to manage than the JavaScript alternative. |
266,943 | I am looking for some advice on getting LVP installed. We have an area of about 2000 sf where we want to install LVP. The area is currently a mix of flooring consisting of a mix of tile, laminate, and carpet.
We will hire a professional installation company to do the job and 2 companies recommended removing all the old flooring for the new installation.

This sounds like a company looking for a quick-n-clean job with max profit. You'll have areas of floor higher than others. You'll have base trim and door casing issues to address. Also, tile can be skimmed with leveler. It's not necessary to overlay it, but that's probably the installer's preference out of laziness or greed.
I would drop all contact with that one. They sound sketchy, like the window replacement outfits who leave you with smaller windows because they don't want to take out the existing trim and reinstall it so they just fit windows *inside* it.
The best solution is usually to strip everything to the same level of subfloor and carry on as if the home was new. | With multiple types of flooring being replaced with LVP, the only 2 companies you should be dealing with are those that recommended removal of all the old flooring. DO NOT consider one that recommended OSB over the tile. Throw away their business card as well. |

] | **Without going into dark UX patterns, I'd recommend many of the techniques from <http://www.goodui.org/>**
Some specific examples would be to recommend a specific product instead of treating everything equally ([#7](http://www.goodui.org/#7)), use the anchoring effect on prices or trim the cents ([#41](http://www.goodui.org/#41), [#51](http://www.goodui.org/#51)), or sell in limited quantities ([#36](http://www.goodui.org/#36)).
Another thing to consider would be the the perception your website or storefront has on the prices your customers expect. The concept of *horror vacui* is why low end retailers (like a dollar store) tend to have very cluttered websites or stores with no space left empty while higher end retailers (like Apple) tend to have more minimal pages or storefronts with ample empty space.
You'll have to decide if you want to create a user experience that leads customers to expect low prices so they know what they are getting, or one that leads to expectations of higher prices (and higher quality) so they are surprised by the prices (and hopefully not disappointed by the quality). | With this request I feel like you're starting to enter into the overlap of Marketing/UX - which can maybe explain why this might be a little different of a request.
Humans are strange creatures when it comes to purchasing - they want to feel like they got a good value (generally - not talking about purchasers that purchase due to high price - aka the very expensive Apple Watch - they purchase it because they can.) However, a good bargain does not always mean the lowest price; it has more to do with the value of the product vs the cost of the product. People want to feel like they paid less than they should've.
Some things that might help that (which again, this isn't entirely UX - this is more marketing/manipulative to the user)
1. Showing a "retail price" and then showing the price they want to sell it at.
2. Showing pictures of the demographic happily using the product.
3. Show reviews/testimonials of other people that have purchased the product. These should be real people.
4. Demonstrate that the company itself is trustworthy - this could be by things they do to give back to the community or even showing that they regularly post to social media.
Hope this helps. Encourage the company to be HONEST with everything - otherwise it will hurt them in the long run. |

The only way to answer this question is user research. Every target audience has their own preferences when it comes to this kind of problem (perceived value). Some demographics will respond to big red prices with "original" prices slashed out; some will favor a focus on product details and imagery, with price as a secondary data point primarily used for filtering. In some cases, choice is part of making the experience sticky; in others, it will just kill your conversion rate.
Get to know your users and draw up some representative user experience maps. Once you understand what motivates them and what they hope to find when shopping in your space, the details will fall into place.

I think most people realize there's a level of bullshit involved with that. Test, obviously, but in general, I'd avoid that altogether. If you want to show that your prices are especially low, consider showing competitors prices along side.
In general, the best way to show affordability is just as you suggest: focus on prices and have the business make sure they are good, affordable prices to begin with.
Beyond that, there's likely a level of marketing and branding that needs to accompany this. |

1. 5 years+ C++
2. 5 years Visual Studio
3. Not much experience using GNU tools ([GCC](http://en.wikipedia.org/wiki/GNU_Compiler_Collection), [GDB](http://en.wikipedia.org/wiki/GNU_Debugger), [make](http://en.wikipedia.org/wiki/Make_(software)), etc.)

I am particular interested in tools that will make my life easier for:
1). project management
2). build configuration via GUI (rather than makefile editing - at least for now).
3). debugging IDE that allows me to set breakpoints and step in/out/over
It would be useful if the IDE suggested has a GUI to ease my transition to Linux, but is also customisable (e.g. can accept hand crafted edited make files etc. - when I have learnt how to create them). This will allow me to have more control over the build process later on.

Try Ctrl + Shift + RightClick to get to properties but visual changes to the icon are not updated even after reboot. I guess that it is cached somewhere. I'll let someone more knowledgeable jump in and that facet answer.

Install Ubuntu on the second. This will automatically detect Windows 7 and set the boot order correctly.
Then boot into Windows 7. Open Run and type diskmgmt.msc. This will open the disk management console. In the bottom section of the console, select one of the empty data disks and right click. Then select "Add A New Mirrored Volume" and select the two data disks. Then format the new volume and you're done. | if you plan to do the system install on win7 and ubuntu, you should install win7 first and ubuntu later, as suggested by MarkM above.

] | I recall reading somewhere that software raid set up in Windows is not easily readable/mountable from Ubuntu and vice-versa (correct me if I'm wrong), you may wish to research that first just in case.
I have a similar set up to what you're after though (I have Win7 on SSD, 2x 500gb in RAID0 for storage, and 1x 500gb hdd for important data with a partition for ubuntu) My steps were:
1. Setup the RAID via the BIOS (I used on-board Intel RAID controller as it seemed the easiest option).
2. Install Windows 7 onto SSD.
3. Partition the 500gb drive from Disk Management in Windows.
4. Reboot with ubuntu disc and install onto the partition.
5. Ubuntu installer should auto detect the Win7 install and setup the boot loader for you automatically.
Only problem with my setup is that since onboard RAID controller is "fake" RAID, I need to do a few more steps in Ubuntu to get the RAID0 volume to show up properly. It shows up fine in Win7 though.
Hope that helps in some way :) | if you plan to do the system install on win7 and ubuntu, you should install win7 first and ubuntu later, as suggested by MarkM above.

98,970 | Ok, I say *PC**s***... but I actually mean *PC*.
I am running a 1-player D&D 5e game for a friend (let's call her Jane), as a way of introducing them to the game. It was only meant to be a "non-canon", one-time-adventure that was supposed to peter out when the actual game started, (we are both PCs in the actual game, that is run by a different DM, with additional players). However, Jane spoke with the DM, and they decided that my game would be part of the characters' backstories.
I was fine with this at first, and I have a storyline to follow, that will eventually end in a way that doesn't affect the actual story of the main game.
For reference, the PC's name is "Cass".
So the story arc I made was:
* Cass' father (an "evil" king, from her backstory) wants to bring her back home after she ran away.
* Enter Big Bad Guy - objective: Bring Cass home. The party has a run-in, and only barely escape with their lives.
* Now the party need to turn the tables, find the Big Bad Guy before they find the party.
* Kill the Big Bad Guy.
Pretty simple, just to keep things short. However, Jane has decided to develop a love interest between the PC's (which I decided to entertain at first), after my PC saved hers, but it has now gotten out of hand, so much so that she has completely abandoned the storyline, to focus purely on the relationship.
It has arrived at the point where I no longer want to run the game, because it has turned into some kind of weird third-person sexting adventure more than anything.
Yes, I do have an interest in Jane, but I don't want to bring that into the game as well. The game is becoming a hassle, because I don't want this to be what it has become, and I'm not sure how I can bring the focus back to the storyline. I want to finish the game, and get back to the *actual* game that is being run for the larger group.
I have spoken to her about this issue more than once, and she does agree that it is taking away from the story development. I have then tried to continue the plot, but every time I do, she always brings it back to the love interest. Every time I have spoken to her about it, she has said that she agrees that the story is not developing, and she sounds like she's sincere about trying to restrain herself, but I have not seen any change in that direction. So I really don't feel she has any real issue with it.
(We do have something going on the outside the game romantically, so there's no need for it during the game that I can see.)
So my only real option seems to be to alter the story in some way to change her focus. How can I get this game back on track? What kind of simple plot hook, twist or in-game device can I introduce to bring Jane's focus back to the story? | 2017/04/27 | [

] | Do not introduce a twist. Just progress the plot
================================================
Your story structure is based on a villain hunting down the players. The benefit of having a villain is that they are people with dynamic plans. They will not wait until the players do something to thwart them, but they will carry out their own plans in the absence of the players.
So all you need to do is bring the villain's plan to fruition in a manner that will make it impossible to have her bring the story focus back to the relationship.
### Present a scene that challenges *her*
If the villain's plan was to abduct her, then if he were to come in and take Cass away, separating her from the party, she *must* respond. It becomes impossible for her to steer the story back into romance.
This is a little "railroad-y," but the fact is, if you find the relationship between Cass and your PC to be the problem, then you take the problem away by removing one of the people involved in that relationship.
But if you really want a twist...
=================================
### Kill your PC (temporarily)
In the villain's attempts to find and abduct Cass, maybe he also kills your PC while doing it. This again removes your PC. Now you can set up a bridge quest where she can find a scroll/potion of Raise Dead, which you can tie back into the main narrative. She must now pursue the quest or else lose her love.
(In the event that she fails this quest, you must also have a plan for reviving your PC. Write it in a way that it does not seem like Deus Ex Machina.)
Remember: as the DM, you must understand the motivations of your players so you can use it to your advantage in the story. Her motivation is her relationship with your PC, so use that as a plot hook.
### Introduce an alternative love interest for *her*
Once you have your PC out of the picture, introduce an NPC who does not appear in the main game, who can then take on the shoes of the love interest. If she goes with the plot hook, then you have successfully written your PC out of this game while simultaneously removing the love aspect from the larger game, where both of you play. It also gives you an NPC whose fate you have much more control over, because this one doesn't have plot armor, unlike Cass and your PC.
If she doesn't go with the plot hook, then you have a fantastic opportunity for a great story. Have the NPC follow her around, helping her selflessly when she needs it. Meanwhile, she is rejecting his advances in true "friendzone" fashion. Play on the emotions of love and rejection while using the NPC and villain to advance the plot you have designed.
Talk to her with your real feelings (of the non-romantic kind)
==============================================================
Let her know that you're finding the third-person sexting weird and uncomfortable. As the DM, you need to be on the same page as she is, and she needs to be on the same page as you are. While she seems sincere that she thinks she is hampering the main story, she doesn't look like she thinks it's a problem. And indeed, why is it a problem? She's still having fun.
Meanwhile, you have not told her that it is not fun for you when she veers away from the main story. Perhaps you've put hours of effort into preparing an adventure for her, and not going down that path feels bad for you since it makes you feel like you wasted your efforts. Let her know this with as much gentleness as you can.
Fade to black when it comes to scenes of that nature. When you sense that the scene is now moving to something like *that*, narrate over it immediately and go to the next day.
This might seem like you're pulling the rug from under her, but...
Does she really want to play the game you want to play?
=======================================================
Consider that the two of you may just be out of sync. Maybe she does not want to play the game you want to play, and vice versa. If there is no point of compatibility between your play styles in D&D, I recommend you stop the game altogether. Continuing to host a game you do not enjoy will only breed dissatisfaction and other negative feelings between the DM and the players, and it might leak out into your real world relationships.
So yes, while it might sting when you drop the game, it only hurts as much as pulling a band-aid. It might just be the best course of action for you in the long run. | Precis
------
The issue seems to be that you're playing two different games, or desire two different results from the game. You're playing 'cops and robbers' and she appears to be playing 'house.' (*Saying* that might be a *bit* impolitic, though. Just a touch (I recommend that you *don't*, in fact, say this or any permutation thereof.))
Additionally, if she's not new to role playing games in general, then she may have 'bad habits' from other games she's played. In many Computer Role Playing Games, for example, there can be a few 'love interest' side-plays or quest-lines (Neverwinter Nights (1 and 2), Knights of the Old Republic (1 and 2), Skyrim, Mass Effect (1, 2, and 3)...that's a lot of Bioware there). Perhaps those color her view.
A Fix
-----
Get your PC out of the picture. I'd strongly suggest capture; the Evil King might know, or suspect, the attachment.
The benefit of this capture to your introductory game has at least two forks that I can see, perhaps there are more. First, it gets your PC out of the picture; both you and she can then concentrate on the story you want without distractions. Second, her character has in-game motivation to go *do the quest*.
This feels much less 'railroad-y' to me than forcing direct confrontations or having *her* character captured; it doesn't remove her agency. Perhaps there was some meeting with a double dealing NPC who was supposed to capture you both, but only she manages to escape. Or perhaps you were separated trying to escape a squad of troops, and were to meet up, but you don't show. She might not even know how your character was captured initially and might have to use 'social' or investigatory skills in game.
This solution provides quite a few possibilities, and you can be released later if it becomes canon in the main game somehow, and she hasn't managed to effect your escape.
Good luck. |
