You even can use cloud services like **[pusher](https://pusher.com/)** or **[firebase](https://firebase.google.com/)** as signaling servers. There is no restriction regarding to the location of your signaling service as long as you make your signaling service accessible from your website.
Here is the link to sample code where I use Pusher service as my signaling service and my hosting server is [codesandbox.io](https://codesandbox.io) .

1. **Web Server**: Where we host our product/application(server behind the URL).
2. **Signaling Server**: handling calls, sessions and rooms. Used to send SDP offer/answer messages between WebRTC devices.
3. **STUN?TURN Server**: Takes care of making sure media gets connected, even if there are firewalls and NATs along the route.
4. **Media Server**: Optional, used when you need to process media in one way or another on the server side.
You don't need to host Signaling Server separately, You can merge your web and signaling server together. But if you want, you can use [firebase](https://firebase.google.com/), [PubNub](https://www.pubnub.com/), [Pusher](https://pusher.com/)

At first, I thought that "interval of time" simply means "a period of time" but after referring to a dictionary I realized that there isn't a definition like that for this word. As it relates to the first definition of the word "cycle", does this mean that the meaning of that definition is "the period between each cycle that takes place"?
It's weird though because things that are happening during the duration of the cycle are also the cycle, but the definition seems to me like it only talks about the time between. Or maybe **interval** simply **means period** and I missed something. | 2022/03/29 | [

] | So, there are three key words at play in the Merriam Webster definitions: *cycle*, *interval*, and *space*. And from my point of view, the definitions are fairly clear. However, in your commentary, you introduce a fourth word: *period*. That doesn't necessarily confuse things, but it might do. The reason is that the word "period" has a technical definition in Physics. So, avoiding that word for now, I interpret the essence of the MW definitions and words as follows:
>
> A **space** of time is the simplest. It's just some time; a chunk of time, if you like; a blob; a clump; and so on. The only additional aspect of the concept of "space" is that we are talking about *contiguous* time; i.e. a *single* chunk/blob/clump.
>
>
>
>
> An **interval** of time is just a **space** with some kind of significance associated with the start and end points. Obviously all (finite) spaces of time have a start and end point, but **interval** is used when those points are of some relevance in the context.
>
>
>
And:
>
> A **cycle** is an **interval** that is subject to being *repeated* in a way that is in some way, more or less, predictable, analyzable, significant, and so on.
>
>
>
So, a **cycle** is a special form of **interval**, which in turn is a special form of **space** (of time).
Finally, back to **period**. In Physics, the **period** of a wave (more generally, of harmonic motion) is the reciprocal (i.e. 1 over) the **frequency**. In that sense, you are correct that "interval" is synonymous with "period". And in everyday use, they are probably safely interchangeable. | I've already given one answer, but I wanted to give another based on one thing you say which you suggest may be at the heart of what's confusing you. First, let me set up an example which may help clarify:
Consider someone working out at a gym. Their workout is based on what in gym terminology we might call a "circuit". It might look like this:
1. one set of five bench presses
2. rest for 30 seconds
3. one set of five squats
4. rest for 30 seconds
5. one set of five deadlifts
And then their gym session as a whole might consist of three of those circuits, with 90 seconds rest between each.
Now referring back to the Merriam Webster definitions, it might be tempting to say that "cycle" is simply a synonym for "circuit" in the above. But in fact the MW definition is such that "cycle" refers very specifically and only to the time itself, and not to the various exercises.
So the thing you say that may be relevant is:
>
> It's weird though because things that are happening during the duration of the cycle are also the cycle, but the definition seems to me like it only talks about the time between.
>
>
>
But that's not exactly correct. It is *not* the case that *"things that are happening during the duration of the cycle* [i.e. the five items in the circuit] *are also the cycle"* Applied to the gym example, the word "cycle" means nothing more than the blob/lump/space of time from the start of the first bench press in a circuit, to the last deadlift in that same circuit.
Also, it's not clear, in the above quote from your question, what you mean by *"the time between"* Do you mean the time between exercise *within* a circuit -- i.e. 30 seconds? Or do you mean the time between circuits -- i.e. 90 seconds? (Or maybe even the time between each benchpress, each squat, etc -- i.e. not specified, but usually very little if any time!)
In summary, using my example:
>
> **Interval** could correctly be used to refer to any of the times I mention: the 30 seconds between exercises, or the 90 seconds between circuits. The key is that both have meaningful **start and end points**
>
>
>
>
> **Cycle** could correctly be used to refer to any one sequence of the five items in my list. The key is that the entire sequence of five is subject to **repetition**.

633,035 | We had a database which was very slow (MS SQL SERVER). Now we figured out, that the indexes were never rebuild oder reorganised. (At the moment it is not clear if this really was the problem but we want to do this frequently now.)
But now the Question: Is it better to rebuild the index or is it better to reorganize it? At the moment we had fragmentation of over 90% so i made a rebuild. But if i want to do it frequently the fragmentation will normally be lower. So would it make more sense to reorganize it instead of rebuild? And would you really make a frequent task for that on every MS SQL Server without exception? Does it make sense on all MS SQL-Servers?
And is there any recommendation how oft this task should run? once a week? once a month?
I also saw in blogs that they make also a "update statistics" after rebuild/reorganisation. Is this recommended or nonsense? (I found both on blogs. -> one said: yes do it -> other: nonsense!)
And what is your experience? Do these tasks (rebuild/reorganzie/statistics) take a lot of performance ?

] | There are volumes and volumes of information out there that answer these questions. The answer is: it depends. Regular index maintenance and statistics updates are crucial, that much is certain. You have to do some research and tailoring of how and when to do it based on your environment, though.
As a good start, read these:
* [**Rebuild or Reorganize: SQL Server Index Maintenance**](http://www.brentozar.com/archive/2013/09/index-maintenance-sql-server-rebuild-reorganize/) (Kendra Little)
* [**Update Statistics: the Secret IO Explosion**](http://www.brentozar.com/archive/2014/01/update-statistics-the-secret-io-explosion/) (Kendra Little)
* [**Index Maintenance**](https://www.sqlskills.com/blogs/jonathan/the-accidental-dba-day-14-of-30-index-maintenance/) (Jonathan Kehayias)
* [**What Caused That Plan to Go Horribly Wrong - Should You Update Statistics**](http://www.sqlskills.com/blogs/kimberly/what-caused-that-plan-to-go-horribly-wrong-should-you-update-statistics/) (Kimberly Tripp)
* [**Understanding When Statistics Will Auto Update**](http://www.sqlskills.com/blogs/erin/understanding-when-statistics-will-automatically-update/) (Erin Stellato) | What Squillman said, but also, you might want to consider using something like [Ola Hallengren's scripts](https://ola.hallengren.com/), which only do as much work as necessary. You can customize the amount of fragmentation in an index before it's rebuilt or reorganized, and this cuts down on the amount of work involved in reindexing.
But yes. It depends on your environment, on the type of load (mostly select, mostly insert/update/delete), etc. |

If it *needs* to last, then it *needs* to be made out of granite. | Concrete pigments are available. But for what I think you are wanting, you would start by grinding/sanding the block smooth, then painting it (black) with an epoxy base coat, then sprinkling it with decorative metallic/colored flakes (the loose fines are cleaned off), and then a clear epoxy top coat is layed over it.

I might also consider using a silane or siloxane (impregnating) based grout sealer for pre-sealing the concrete (which might not be worth the cost- I'm not sure; since you are covering it with epoxy anyway). But to estimate, lets say a quart costs $20, and it will basically cover 100 square ft, (or 10 headstones)... I might be tempted to do it because it might help if the concrete starts to crack or chip after a while.

* [Iris Flower Data Set](http://scikit-learn.org/stable/auto_examples/datasets/plot_iris_dataset.html);
* [Titanic Data Set](http://www.kaggle.com/c/titanic-gettingStarted);
* [Motor Trend Cars](http://stat.ethz.ch/R-manual/R-devel/library/datasets/html/mtcars.html);
* etc.
But does anyone know similar datasets for networks analysis / graph theory? More concrete - I'm looking for **Gold standard** datasets for comparing/evaluating/learning:
1. centrality measures;
2. network clustering algorithms.
I don't need a huge list of publicly available networks/graphs, but a couple of actually must-know datasets.
EDIT:
It's quite difficult to provide exact features for "gold standard dataset", but here are some thoughts. I think, real classic dataset should satisfy these criteria:
* Multiple references in articles and textbooks;
* Inclusion in well-known network analysis software packages;
* Sufficient time of existence;
* Usage in a number of courses on graph analysis.
Concerning my field of interest, I also need labeled classes for vertices and/or precomputed (or predefined) "authority scores" (i.e. centrality estimates). After asking this question I continued searching, and here are some suitable examples:
* [Zachary's Karate Club](http://networkdata.ics.uci.edu/data.php?id=105): introduced in 1977, cited more than 1.5k times (according to Google Scholar), vertexes have attribute Faction (which can be used for clustering).
* [Erdos Collaboration Network](http://www.orgnet.com/Erdos.html): unfortunately, I haven't find this network in form of data-file, but it's rather famous, and if someone will enrich network with mathematicians' specialisations data, it also could be used for testing clustering algorithms. | 2014/06/26 | [

Well, there is no clear answer except of Zachary's Karate Club!
If you do a literature review in Community Detection algorithms you'll see that almost all shining papers use different networks. My suggestion is going through what Andrea Lancichinetti and Santo Fortunato did for benchmarking graphs. They proposed some benchmark graph generation algorithms e.g. [this one](http://arxiv.org/abs/0904.3940).

104,164 | I've got gate valves (I think that's what they're called) for all of my water shutoff valves. It's a pain to close them, and they don't quite close all the way anyway, so I was thinking of replacing them with quarter-turn ball valves.
I have no experience soldering / sweating pipes, so would like to use compression fitting valves or threaded valves (with threaded-to-compression adapters to connect to existing copper). Is there anything wrong with this approach? Would it be acceptable for any water shutoff in the house - main, water heater, sinks, dishwasher, toilets? | 2016/12/10 | [

] | Yes, we typically are recommending 1/4 turn ball valves for valves that are not used very often. This would include sink stops, laundry stop, and main shut off. However each of those requires a unique solution to replace them per circumstance.
The hose bibs we would not recommend a 1/4 turn ball valve as ball valves are not designed to be used often and should not outlast a globe valve which is typical on hose bibs. Also, if you have freezing temperatures at times, ball valves for hose bibs are inherently not frost free.
A push fit type fitting with rubber gasket (shark bite) for the supply side of the main shut off is generally not a good idea as they are not a very robust connection for something that is always on, does not have an easy means of shutting off (to some people), and is usually hidden. All other locations should be good for a push fit type fitting however I would not personally recommend them else where either if you can avoid them.
In general, if it is a sweated connection, I would keep it sweated or threaded; and only resort to push fit (again, shark bite style) fittings if you have to. Example would be the water is not shuf off completely with the main and city shutoffs off and you cannot get the water away from the connection long enough to sweat; in cases like these we have resorted to a push fit connection.
Also, there is another common type of connection, a compression type connection, that utilizes a brass or plastic compression piece to "squish" around the pipe and seal things; these are usually very reliable but are only readily available on certain types of valves.
For the main, I would recommend someone properly sweating in some sort of solution **even if you need to hire it out**. Many times we convert to PEX for simplicity and speed but we still sweat on the adapters on either side of the conversion.
The other locations are not typically sweated connections and should be easier for you to replace as a home owner with a good set of plumbing tools and sealants. Hose bibs many times are actually sweated and again, we sweat on an adapter farther back and usually convert to PEX. | Presumably the existing stop valves are sweated on. These valves are almost certainly the type with a rubber washer, as opposed to a gate valve. If you have no experience sweating, then you might have trouble getting them off.
If you have copper tubing water lines, you could avoid dealing with a torch by cutting off the old valves with a tubing cutter, then attaching the new ones with compression fittings. This would reduce the pipe by an inch, so you would have to have enough length to do that. Also be sure your tubing is not out of round.
You could also use valves with push on seals such as 'Sharkbite'.
I have some experience sweating, but have gotten out of practice. I removed a sweated on stop valve on a toilet and put on a ball valve with compression fitting and ran into a little trouble. I got the old valve off easily enough, but did not wipe solder off from the copper water supply tubing. I did not detect a blob of solder which collected on the bottom of the tube with the result that the compression nut would not go on. When I finally realized what was happening I tried to reduce the blob with emery cloth with troublesome results. Finally I reheated and wiped the end of the tubing, but before I reheated I reduced the diameter off the tubing so that when I tightened down on the compression nut the fitting leaked. Finally I was able to tighten down enough to stop the leak, but the nut is or is close to being bottomed out.
I did have enough copper pipe to cut it off and place the new valve closer to the wall, but this just goes to show that a deficiency in experience and competence can lead to problems. If you decide to tackle this job yourself, start with the most accessible and least critical fixture to find out how to do it. |
2,589,680 | I'm looking for a free code profiler (performance profiler, not a memory profiler) which works for VSTO applications (specifically Excel in my case, but I gather that if it works for one, it should work for all).
I have tried Eqatec Profiler, but it can't seem to launch the application from the profiler (The Run app button is greyed out, which I'm gathering is because the VSTO application is compiled into a dll which runs in-process with Excel.exe).

] | What you're doing should be possible with [EQATEC Profiler](http://www.eqatec.com/tools/profiler).
When you're simply instrumenting one or more DLLs then there is no distinct "application to run": you simply have some instrumented DLLs, but the profiler doesn't know in what way you intend to use them.
However, the instrumented assemblies are (along with the runtime-module, EQATEC.Profiler.RuntimeFullNet.dll) always completely "self-contained", meaning that they perform the timing themselves as soon as the methods within them are used. So you simply need to have your VSTO app load the DLL as usual and voila, the DLL will itself start accumulating timing information and start listening for a connection from the profiler with which you can then take snapshots etc.
So to summarize:
1. Build you DLL and keep the profiler running
2. Have your VSTO app load the DLL (however you do that)
3. The profiler and instrumented DLL should now be connected (see the Run-tab)
4. From within the profiler you can now take snapshots

Unless you have some evidence that this is the general response, you shouldn't present your personal confusion as being an "inherent" property of the phrase. And the standard isn't whether a non-native speaker who has learned basic English is confused, it's whether a native speaker is. Language generally doesn't develop with ease of foreign speakers in mind.
You describe your incorrect interpretation as the "instinctive" understanding, but that "instinct" isn't necessarily a natural, objective way of looking at language, rather than an arbitrary pattern that you are so used to that it seems "normal". Native language acquisition involves wiring the brain to think in certain ways, and it's natural for those ways of thinking to feel universal, rather than particular to your linguistic community.
While it may take some thought when first seeing this to figure out what it means, it is pretty straight forward: it is the furthest from the truth that it can be. It is the most not-truth possible.

88,132 | Is there a discipline teaching how to design either a contract, in terms of logic and real-life feasibility, not just law.
A contract designed by lawyers is expected to be efficient if the parties involved have a conflict and their conflict reaches court. But what about contracts which are designed to prevent such course of action on the first place? That is, contracts, which put such conditions, that someone likely to violate them, would rather give up the whole deal, than accept the contract with a hidden intention to break its rules, later on? Is there a subject dedicated on that?
A contract or just even a short set of rules, does not need to be a legal one, in order to be effective. You could have an informal stipulation about the rules of relations between roommates, neighbours, co-workers, etc and if well designed, it could be no less robust than a legally bounding agreement.
As far as I was able to research, there's a discipline named "contract theory", but it belongs to the narrower field of economics and it seems not well suited for direct application in practice. | 2023/01/12 | [

] | [united-states](/questions/tagged/united-states "show questions tagged 'united-states'")
In the United States, both among practicing lawyers, and in the academic field, disciplinary boundaries are very loose. Looking only for "contract theory" would miss much of what is going on.
Lawyers who practice primarily in the area of pre-litigation contract law are called "transactional lawyers". Transactional lawyers have the same professional license as lawyers who engaged primarily in litigation, or lawyers who do both, but they choose to take on work of that type. Frequently transactional lawyers specialize even further. One lawyer might do primarily residential real estate closings. Another might handle mostly commercial real estate closings. A third might handle real estate development and construction law. A fourth might handle mergers and acquisitions. Another might handle mostly banking contracts. Another might mostly deal with insurance contracts. Another might handle mostly estate planning. A different lawyer might focus on condominiums and home owner's associations. Other lawyers focus mostly on oil and gas transactions.
In general, practicing lawyers are much more likely to focus on a particular kind of contract than on contract design generally.
This is also true in academia, although academics tend to examine issues at a somewhat greater level of generality than practicing lawyers.
In academia, in law schools, there are lawyers who focus heavily on studying contract law. There is even a [contract law professor's blog](https://lawprofessors.typepad.com/contractsprof_blog/). Many professors who study contract design at both the law school level and in undergraduate business schools identify instead as [business law professors](https://lawprofessors.typepad.com/business_law/).
Other professors who specialize in contract design focus on only particular kinds of contracts, such as [agricultural law and taxation](https://lawprofessors.typepad.com/agriculturallaw/), [merger and acquisition contracts](https://lawprofessors.typepad.com/mergers/), [securities law](https://lawprofessors.typepad.com/securities/), [real estate financing](http://www.refinblog.com/), [marijuana business law](https://lawprofessors.typepad.com/marijuana_law/), [international trade law](https://lawprofessors.typepad.com/inttradelaw/), and [international finance law](https://lawprofessors.typepad.com/intfinlaw/). Contract design in all of these fields is also pervasively influenced by [tax law](https://taxprof.typepad.com/) - with undergraduate tax law in accounting programs tending to be more focused on compliance and law school tax law more focused on transaction design.
Economists also study contract design. One of the main issues explored by economists is the question of under what circumstances it is better to structure economic activity within a single business raising issues such as the "theory of the firm" and agency problems, on one hand, or to structure economic transaction instead through contracts between multiple firms.
Both legal scholarship and economic scholarship tend to be weak in what I call "descriptive economics" which is the study of what contracts and transaction structures are commonly used in real life to deal with particular kinds of situations.
In short, the subjects about which you express interest are studied, but professionally, study of these subjects is highly fractured. | This is the work of a [solicitor](https://en.m.wikipedia.org/wiki/Solicitor), especially one who specializes in contract negotiation, or in the subject area to which the contract relates (i.e. family law, employment law, etc.), but most general-practice solicitors would have the skills you discuss.
Academic scholarship can be found under the terms "legal design" or "regulatory design." |

53,732 | So, for portraits or videos etc - everyone always says to get some light, ie softboxes. Okay, so you search softboxes online at your favourite webstore and find that no two softboxes are the same:
We have softboxes in different shapes and sizes, and in with different number of 'heads'. A head being a fixture for a single bulb. Some softboxes fit just one bulb, others fit as many as five bulbs.
So this means that some softboxes will be incredibly brighter compared to others. For example, they ship with 135W CFLs included, advertised as 675W each - mulltiply that by 5 bulbs in a single box and this seems to be a bit excessive?
**Is there a rule to dictate how many heads are generally needed in a softbox?**
I know I could always not add all the bulbs, or move the softbox further away - but space can be limited, and the head count can affect price. | 2014/08/25 | [

] | First of all, buy a head with adjustable power! :-) Moving heads to control emitted light is usually a bad habit - the closer the soft-box, usually the better the result is! (You want to make the light source to be NOT point-like, so the closer it is, the softer the shadows are, and that's the point.)
Second of all: are you asking how much light you are planning to emit from a soft-box - from us? :-) Your use-cases may greatly vary... You can do portraits with relatively low light, or you can do high-speed-sync action shooting of a group on the field! With a group of heads!
And lastly: it is all different if you are using flashes or continuous light for video... The flash emits a relatively high energy density short pulse, but then the head, the soft-box can cool down during recharge, idle time. If you have continuous light, you need much better ventilation, etc.
The easiest to solve your problem is: find a studio nearby, go there, make some shots, check the properties of the heads and soft-boxes there, and then you will have enough data to purchase equipment. (Make sure though that you go to a place with some good quality equipment.)
My advice: in general, an octa soft-box is always a good idea to start with (creates a light similar to what an umbrella creates, but smoother. Have you tried a simple umbrella and a flash?). I would buy a big octa first, then a huge rectangle soft-box next. I always use these extensively, however, I cannot justify buying them, as I can always go to a studio if they are needed.
Also make sure that you buy equipment for outdoor use if you want to use them outdoors... | A softbox is a light modifier…. It affects the shape and quality of light. An Octabox would create a cone of light; a rectangle softbox creates a pyramid. It would be easy to evenly light some ones face using a small softbox the size of their face. It would be easy to evenly light an entire person from head to toe using a large softbox the size of the person. Since the large softbox is lighting a larger area it needs more power for the same exposure. There is a simple way to tell how much power you need: If you wish to overpower the ambient lighting; your light must be brighter then the ambient light. If shooting in the dark, no ambient light, any light you use will have enough power. If shooting in full sun your light must have more power than the sun! |

67,421 | Probably questions about tires are an everyday-question on this forum.
I own a GT mountain bike. I was running some tires more for dirt/off-road, but where I moved to live now I have also been riding a lot on tarmac/asphalt/pavement. So I was looking for some tires that would give me:
* **a good speed on these flat roads** (gosh, I have strong legs and still cycle fast, but these actual tires kill me)
* **still a good grip on off-road dirt/gravel**.
I came across the CONTINENTAL Race King ShieldWall (this is the upper-intermediate version of Race Kings).
They sound to have a good grip for off-road, but also appear to be fast on road (of course not as fast a road bike, I'm not looking for it anyways).
Now, bearing in mind my needs stated above, a question came to my mind - and when I search I only see topics/posts/answers from few years ago:
1. Should I run 2.0" on both rear and front wheel?
2. Should I run 2.2" on both rear and front wheel?
3. Should I run 2.0" on front and 2.2 on rear?
4. Or should I run 2.2" on front and 2.0" on rear?

] | Looks like a good tire for both uses. The speed king would be faster on road, but not as good off road. If your off road is tending towards non-technical and dry hardpack, consider speed king. Size down not matter - narrow for more road/hard pack, wider for more technical off road conditions.
Consider something like speedking rear and raceking front. With more weight (70%) on the rear, the rolling resistance is relatively more important on there ear. The race king ont he front will provide more predictable traction for steering and control when off road.
One thing to watch is sealed/paved roads, especially when wet. As you lean into a corner, you transition onto the nobbly shoulder and loose traction when you most need it. Something like the speed king can catch an unwary rider out.
Ideally you have two bikes, second best is two sets of rims, one for off road and other for on road. | An on-road tyre is smooth and has no significant tread, whereas an off-road tyre has some combination of large and small lugs to suit specific surfaces.
There do exist tyre profiles that are smooth around the "equator" but develop lugs further out around the edges.
It really makes little difference in the width of your options - 2.0 inches to 2.2 inches is 10% different on width, and you won't notice any practical difference. There's a current trend toward wider, but that's 28mm which is about half of your 50-55 mm options.
Also, you're riding a squishy MTB on the road - no amount of fancy tyres will make it "fast" so consider adding a second bike to your collection, rather than compromising the off-roadness of your existing bike. That second bike could be a rigid MTB/commuter, or a dropbar road bike.
Depending on the condition of your current tyres, just keep riding them till they're worn out. As the lugs wear down, you will approach that "smooth band" around the middle. If your current tyres are still decent,then store them for some future rides, though be aware its irritating to change tyres a lot, and potentially damaging for the rims and tyres. |

] | Usually non-immigrant Category B visas for employment have the name and position of the company you are going to work for written on them. While this does not mean you cannot use the visa to enter Thailand, you will have trouble applying for a work permit for the second company after coming to Thailand.
Also, you cannot have an existing valid visa of the same type while applying for visa on behalf of the second company. In this case you will have to explicitly get the first visa voided (cancelled) before applying for the second one. All this can be carried out at the VFS center itself. | A visa is not attached to a particular company. Once it is issued, you can use it to enter.
Note that this is different from an extension of stay which is done at a local Thai immigration office. Extensions are tied to the reason of extension. So if you are extended by reason of employment, the extension is voided as soon as your employment ends (fired/quit). Similarly, if you extended by reason of marriage, that extension is invalid the day the divorce is finalized.
You dont automatically get 7 days to leave the country. You must apply for that 7 day extension at the local immigration the next business day.
This is why some people opt for a Multiple Entry [ME] Non Immigrant visa (Non-B in your case) vs a 1 year extension of stay. If you get fired or quit, your visa is still valid. Just tell your employer that every 89-90 days you will need time for a border hop.
Not sure how easy ME Non-imm will be to get for Indian national though. Even if they do issue ME non-B, sometimes the neighboring Thai Embassies will want to see 8-10 months remaining on the work permit as a condition to issue ME. |

**.fla** — files contain source material(images, movies, fonts, code, etc...) for the Flash application. Flash authoring software can edit FLA files and compile them into .swf files. The Flash source file format is currently a binary file format based on the Microsoft Compound File Format. In Flash Pro CS5, the fla file format is a zip container of an XML-based project structure.
**.as** — .as files contain ActionScript source code in simple source files. FLA files can also contain Actionscript code directly, but separate external .as files often emerge for structural reasons, or to expose the code to versioning applications.

] | Two reasons (and solutions) I found when I wanted fast replies from my DHCP server.
1) My DHCP did a ping of the address it wanted to allocate. This added 3 seconds delay. I removed this by changing the DHCP config to have a mapping for MAC Address to IP address. This is basically using DHCP to allocate a static address. This removed the 3 second delay for me.
2) I have an isolated network, however, you may get this at times. There was a DNS look up being done, which for me resulted in many seconds delay from getting an IP Address from DHCP. In the DHCP server config there were options for our domain and DNS servers. After removing DNS options and above change I got instant replies from the DHCP server. (\*\*)
These issues were what I found in my setup. Your milage may vary.

] | **Short answer: Unless stated explicitly otherwise, always formal.**
It is not about being taken seriously, it is about *interviewee* showing respect to the *interviewers* and taking the job application process seriously. | A suit is generally considered to be the de facto standard business attire, meaning that when going someplace to conduct business, it is always considered appropriate to be worn if you are not already familiar with who you are meeting with. Likewise, on an international basis, nobody should be offended if you show up to an important meeting wearing a suit and in some cases, people will be offended if you do not wear a suit.
An interview is a formal business occasion and as such, a suit would be considered appropriate for the occasion unless you are explicitly told by the folks you are interviewing with that they have a "casual office" or explicitly tell you not to wear a suit.
As a matter of personal practice I generally wear a suit when interviewing and when I was told not too I still wore business casual. However, when I have had to interview candidates I've also extended the same expectations and wore a suit for the occasion myself. |

] | This is for Silicon Valley:
My rule of thumb is to dress nicely enough to show I made an effort, but not so formally as to make my interviewer uncomfortable or make them think I know nothing of the Valley culture. I'm a woman, so that usually boils down to nice dark-wash trouser-cut jeans, a nice shirt, good (clean) low-heeled or flat shoes, and maybe a jacket (but I always wear jackets :) ).
One thing to keep in mind is that you may be asked to contort yourself to write on a very small whiteboard, and there may be a bunch of kneeling and reaching. So if you wear a jacket, be prepared to take it off and make sure it wasn't covering up a hole or stains. If you wear heels, make sure you can stand in them for a while comfortably, and that if you need to think on your feet (literally) you won't be distracted by the howling pain in your compressed little toe. This is also why a knee-length or shorter skirt is usually a bad idea, though I've seen it being pulled off successfully.
I've interviewed a lot of people, too. If someone shows up wearing a suit I'm usually pretty amused, but it doesn't really count against them. OTOH if someone comes in wearing a wrinkled t-shirt and dirty jeans, that's not a good first impression because it broadcasts a lack of caring and professionalism. | It depends on the culture of the company. If you have contacts within the company, you can ask them for advice.
If you're not sure, err on the side of over-dressing. Some companies absolutely do frown upon under-dressing, whereas it's pretty rare for an interviewer at any company to be upset that a candidate is over-dressed. |

] | **Short answer: Unless stated explicitly otherwise, always formal.**
It is not about being taken seriously, it is about *interviewee* showing respect to the *interviewers* and taking the job application process seriously. | Unless you show up wearing a white tuxedo, you will almost never have points taken off for being too formal, so why chance it. I would say suit by default, and button up shirt and khakis at an absolute minimum and only if you happen to know that the place is super casual.

If you have a CF that takes at most 9 minutes to execute, even if you extend the deadline to 9 minutes, this is only on the CF side and the CS will stop waiting, leaving the request's status as UNKNOWN (therefore, FAILED).
If you are creating the CS from the sdk, you should take a look at the parameter [--attempt-deadline](https://cloud.google.com/sdk/gcloud/reference/beta/scheduler/jobs/create/http#--attempt-deadline), which will allow the CS to wait more.

] | Asynchronous replication and asynchronous mirroring mean the same thing to me, but could mean different things depending on the context you're seeing them in. In general, asynchronous always means that writes are being acknowledged by the primary device before confirmation is received from the target.
One important variable is consistency. Assuming we're in the world of SCSI here (clock level, LUNs, FC/FCoE/iSCSI), asynchronous almost always means that periodically, the system will take a consistent point, and ensure that all bits for that point are replicated. If the link breaks between consistent points, it reverts back to the most recent consistent point. On some more high end arrays, you can get guaranteed in-order delivery, which guarantees crash-consistency at any point, and the only data lost is the data that was in transit at the time of disconnection. | In storage and databases the tradeoff in synchronous vs asynchronous replication is reliability vs speed.
With synchronous replication, the master will wait for writes on the replicated partner to be *confirmed*. This adds significant latency to any write operations. The latency is significant because often this replication goes over a network connection.
With asynchronous replication, writes don't have to be confirmed. This makes for faster writes, but you risk some data loss in the event of a failure.
The choice you make really depends on your business needs or desired result. In something like finance a little lost data can mean millions of dollars. In social networking, people are generally more concerned about a responsive site than a lost "poke". |

] | Actually, in the US, applying for a doctoral degree is almost always preferable to applying for a masters. The reason is that doctoral admission almost always comes with some sort of funding and masters admission seldom does.
The advice is to apply to several institutions that cover a fairly wide range of "rankings". If you apply to only one or two programs you are unlikely to be successful because of the competition. If you want a PhD "eventually", do that now. | The only reason to apply to a MS program first would be to get some extra credits/experience with higher-level courses which may be needed for PhD programs at better schools. If you already have all that covered and want to do research, going straight for PhD makes more sense. In most departments these days they award MS just for failing your PhD quals, so there isn't much point of applying for MS except for that extra credits reason.

11,586 | A client has a small rehab clinic. They do everything using paperwork .
There about 5-6 doctors. So it is a multi-user app.
They need to keep some forms, medical records etc about each patient.
There are some security/privacy requirements.Doctors should not be able to see each other stuff.Like physio seeing psychiatrist notes for a patient.
Forms are somewhat big and would require dozen of columns in a relational database.
Those who certify the clinic with ISO stated that certified software must be used. However asking what certified software is they responded MS Access. I don't get how MS Access out of the box is certified for storing medical records without developing some forms, vba code etc.
So is MS Access more suitable than a simple web based local app using a database for storage ? I dont have much experience with MS Access and if I go this road then I wont be able to keep up with the deadline as I have zero time to learn access (having other projects running) | 2014/09/18 | [

Later if you want a web interface you can do it either using Access itself or ASP.NET.
The thing with Access is that it can quickly end up being corrupted when one of the clients connected to it crashes. This happened to a client of mine long time ago and I learned my lesson. Luckily he had taken a copy the night earlier.
Hope this helps! | If it's just you or your team is less than 5 people developing, look at Visual Studio Community and adding on LightSwitch rather than Access. It's kind of midway between Access and ASP.NET.

However, I want to add a warning. Be careful just handing off the decision on whether something gets added to the salespeople/management.

Management might easily agree that a button should be moved a couple pixels over.

Moving from a one to one relationship for items to a one to many relationship is something that many non-technicals see as 5 minutes of work. It isn't.
Highly complex requests are going to have to be refused anyway, but it will be a lot less graceful if sales agrees and then development tells them it cannot be done.

If your manager comes to you and tells you that the customer is paying for a feature or a change, and tells you to do the work, then you do it. Otherwise you don’t.
Find out who in the company can make a decision whether work will be done at all, and for what price. Then when you get a request, you say politely “I’m sorry, but this is something I cannot decide. Please contact so-and-so about it”.
PS Just because the customer is willing to pay doesn’t mean they get it. Someone quite high up needs to decide about the company’s strategy. Any request costs money, not just for the work done, but also for all the other work you *should* do instead. |

Find out who in the company can make a decision whether work will be done at all, and for what price. Then when you get a request, you say politely “I’m sorry, but this is something I cannot decide. Please contact so-and-so about it”.

You have information they need, and they have information you need.
You need to know what you *should* do for the clients. The sales folks need to know what you *could* do for the clients, and how hard (read: expensive in salary hours) it would be.
You don't want to sever all contact with the customers. It's good if developers have a clear idea of what the customers actually want to do with the software. But you do need to get the sales people involved more. Handling your problem, is part of their job. |

You should record all the client requests in an issue tracking system, but place them into the backlog (so they aren't worked on). The project manager (you should have one, of some sort, I hope) will review the requests on a regular basis, and decide which ones should be worked on. That PM is the person who should have the business and contractual knowledge (from the client) and techncial knowledge (from the request) in order to prioritize the work.
Once you have that type of workflow in place, you never have to say no to a client - you always say that you'll ticket it, and Ms XYZ will prioritize it. | I agree with all the other answers on that you need the contract info to make these decisions and pass the negotiation of features onto whoever is handling those.

171,614 | Firstly, Allow me to apologize if this is not relevant on on topic for this stack exchange, but I'm at a loss here and hope someone can help.
I have created a rough map for my world using Krita (Similar to Gimp) which i use for internal reference while doing other world building.
What I am looking for is a program or tool (offline not cloud based) that will allow me to drag and drop "pins" onto it which when hovered over will display text (or can be clicked on for the text either works) the way Pins work on services such as google maps.
I am currently using the classic method of putting "1" "2" "3" etc. on the map and having a separate legend file which references them, but it's seriously clunky.
Google has failed me no matter what I've tried.
Dose anyone here know of something that fits what I'm looking for, or a better answer that hasn't occurred to me.
I'm mainly trying to do this for the small things, Specific bridges, monuments, and other points of interest that otherwise don't warrant their own specific legend markings.
Again I'm sorry if this is to far off-topic, but as it relates to world building it seemed like it fit and I can't think of a better place to ask.
Edit:
The answers that have come in while informative have not resulted in what i'm after (clearly due to poor phrasing on my part)
I'm really looking for a downloadable program that is not web or cloud based, similar to using Ms word, instead of google docs.
I have the image i wish to use as the map i just lack the ability to pin or annotate it.

343,713 | We've implemented a folder sync across two servers sitting in two different data centres using Unison. It's crucial for us that this folder sync work as expected as our SLAs depend on the data being available at both ends.
So far Unison has been working like an ace, no problems.
However, we need to implement a mechanism to ensure that someone is notified if Unison does throw up an error. I know of the standard Unison logs. But in addition to the standard logs I'm looking for another log that would only report errors, not the entire verbose log of everything the Unison service is doing.
This way we can monitor this 'errors-only' log and send out emails or SMSs to notify the correct individuals. | 2011/12/23 | [

Then, there is a service check in Nagios that checks for the presence of these files, and sends up an alert if found. This way there is the verbose Unison log for more information, a quick way to know if something went wrong, and automated email/SMS if/when it does. You could also use cron for this if something like Nagios isn't available. | I don't test but you can maybe use the logfile directive to have all the modifications, and the quiet to stop the stdout.

2,095 | I've been thinking about getting a Commodore 64 machine. However, I realise there's obviously no video cables I have that will work. But when I looked online there are many people using S-Video to VGA and stuff like that. My TV is quite old and has an aerial (RF antenna) port in the back but I'm not sure if that would work. Other than that I can't find the S-Video to C64 cable that all these videos show. (They then put it into an S-Video to VGA converter)

] | The VIC-II chip inside the C64 computer outputs a S-Video signal, which is mixed and modulated into the matal box that contains the UHF modulator circuit. Earlier models made composite video available on the A/V DIN connector. Later models also made separate componentes (luminance and chrominance) available as well.
For the sake of image quality, and as you say you want to use your C64 in a modern TV, it's better to forget about the UHF output.
Most modern TVs still have a composite video input (yellow, white and red RCA connectors at the back). If yours doesn't have it, it may have it in form of a TRRS output and you will need a cheap TRRS -> RCA converter. Others have it embbeded into the SCART connector. Others share the composite video connector with the YPbPr (video component) connector (actually using the Y connector (green) for both luminance and composite video). So, your first and more succesful option would be to get a composite video signal and audio signal from the C64 A/V DIN connector and feed with it your TV.
However, if you find your TV supports S-Video (normally, a 4 pole mini-DIN connector) and your C64 is a later model that outputs S-Video, then you can try it as well, for a slighly better video output.
So your first (and cheaper) options are first to find an A/V cable for your C64, such as this one:
[](https://i.stack.imgur.com/gHxsp.jpg)
Or this one, if you can confirm your TV supports S-Video input and your C64 can output it as well. Note that this cable can also be used with older C64 computers / TVs which supports only composite video.
[](https://i.stack.imgur.com/OlRX9.jpg)
If (and only if) your target monitor doesn't accept either composite video or S-Video, then you can try a converter box. This one I bought some time ago can accept both composite and S-Video inputs.

This is the device, once unboxed and connected to a composite video source and to a TFT VGA display:
[](https://i.stack.imgur.com/Op542.jpg)
This is how I see a C64 computer in my TFT monitor. Its monitor OSD shows me which VGA output resolution I'm using. Although it is using the composite output from the C64, I think it gives a very decent image.
[](https://i.stack.imgur.com/xp3nm.jpg)
There are several resolutions and refresh rates availables:
[](https://i.stack.imgur.com/eDRtv.jpg)
The converter brings its own OSD menu, from which we can adjust many parameters. This is just one of the sections:
[](https://i.stack.imgur.com/7RUsY.jpg)
This particular VGA converter box allows a VGA source too, so you can share your mnitor with your PC and your C64 without the tedious connector unpluging and pluging. Just pressing a button. You can even have a PIP (picture in picture) output.
[](https://i.stack.imgur.com/EIwQx.jpg)
Of course, you can go for a composite-to-HDMI, or S-Video-to-HDMI converter box, if you are willing to use a monitor/TV without VGA input. Amazon sells them with different prices and options. These HDMI converters usually convert the audio signal also, so you have a true HDMI audio/video signal. I have one such converter, but I haven't tried it yet with a C64. | You can use the aerial port on your TV, but you probably need a switch box for that to work. Every C64 came with the cable and switch box in the box but they are infrequently used today because the picture quality is the lowest.
The C64-to-S-Video adapters are available on eBay. You need a C64 monitor cable to plug into it.
Converting composite or S-Video to VGA is more complicated but there are devices which can do it. There is a popular one called the GBS-8220, also available on eBay, that can convert composite/YUV and CGA/EGA/RGB to VGA. |

BTW, RGBi stands for Red, Green, Blue, intensity. It was a digital signal providing for 16 sharp colors, 4 bits for each pixel. They were black (no bits set), light grey (R+G+B bits set), red, green, blue, cyan (B+G), magenta (R+B), and yellow (G+R). Each of those base 8 colors had an enhanced intensity when the i-bit was set. Among everything else, this turned light-grey to white, and black to dark-grey.
I used my C128 with a Sears *Total Video System*. It combined a TV and monitor modes for monochrome, composite, and RGBI. This was perfect for the C128 because the composite worked with C64 mode and the RGBI worked with the C128 modes. (Plus it was my TV.)

It will still "look cool" and allow you to "program with limitations". You will gain a crisp 80-column display, ability to program for both the 6502 and z-80 CPUs, and a much better built-in BASIC.
BTW, RGBi stands for Red, Green, Blue, intensity. It was a digital signal providing for 16 sharp colors, 4 bits for each pixel. They were black (no bits set), light grey (R+G+B bits set), red, green, blue, cyan (B+G), magenta (R+B), and yellow (G+R). Each of those base 8 colors had an enhanced intensity when the i-bit was set. Among everything else, this turned light-grey to white, and black to dark-grey.
I used my C128 with a Sears *Total Video System*. It combined a TV and monitor modes for monochrome, composite, and RGBI. This was perfect for the C128 because the composite worked with C64 mode and the RGBI worked with the C128 modes. (Plus it was my TV.) Here is a [1985 article](http://www.atarimagazines.com/compute/issue58/computer_video.html) which includes descriptions of the Sears TVS as well as other flexible monitors of the period.
If you wish to avoid buying an old separate monitor/TV, see [this article](https://sites.google.com/site/h2obsession/CBM/C128/rgbi-to-vga) for building an RGBI to VGA converter. Sigh, it looks like your TV doesn't have VGA either. However, this should hook up to just about any computer monitor you happen to have. |

141,609 | The description of the [Slow](https://www.dndbeyond.com/spells/slow) spell says:
>
> You alter time around up to six creatures of your choice in a 40-foot cube within range. An affected target's speed is halved...
>
>
>
It alters time around creatures and reduces their speed to half. Could this be used to affect a falling creature?
Which of the following accurately describes how the Slow spell interacts with falls and falling damage?
1. The creature moves at half speed and so falls at half speed, taking half damage
2. The creature moves at half speed but their relative time bubble they move at regular speed. They hit the ground after twice the time but still at the same speed and damage.
3. They are in free fall for double the time but gravity interacts for the duration. So actually they personally have double the speed. They take additional damage?
4. They fall at the same rate (aka their bubble continues falling) but inside it they impact at half (double?) speed and take half (double?) damage.
The mental picture for me is definitely the slow-time effect where they are in a bubble of slowmo, slurred speech and all. So I feel like it would have some interaction, but I'm not sure what. | 2019/02/21 | [

A creature's speed does not interact with the falling rules. | The Slow speed cannot help a falling creature.
==============================================
Falling speed and falling damage are not related to a creature's speed.
[The *Xanathar's* falling rules](https://www.dndbeyond.com/compendium/rules/xgte/dungeon-masters-tools#Falling) state:
>
> The rule given in the *Player's Handbook* is simple: at the end of a fall, you take 1d6 bludgeoning damage for every 10 feet you fell, to a maximum of 20d6. You also land prone...
>
>
>
It goes on to mention some optional rules, one of which is the maximum rate of falling, which states:
>
> The rule for falling assumes that a creature immediately drops the entire distance when it falls. But what if a creature is at a high altitude when it falls. ...
> When you fall from a great height, you instantly descend up to 500 feet. If you're still falling on your next turn, you descend up to 500 feet at the end of that turn.
>
>
>
Nowhere in the falling rules is a creature's speed mentioned. (There is a mention of a flying speed, but if your target has that, this wouldn't be an issue.) |

] | You can simply transfer the money as usual (wire transfer, or any other means). There are no tax implications for moving money into and out of the US, and nobody will care (unless you transport it in cash).
The tax implications are from having that home in the first place. You are required to report on your tax filings all income and property outside the US, although it is of course possible that the house produced no income for you.
If the house was owned by your mom, and she is gifting you the amount now, this is a *taxable gift*, which *she* - not you - has a US tax liability for, if she is a US person (and independantly, potentially a tax liability in her home country, which you didn't name).
For a mother-to-son gift, the US tax exclusion is 15000 per year; only money above this is taxable. Note that this limit is per person, giver and receiver, so if either your mom or you are married, both parents could gift each to both of you each 15000 tax free, resulting in 60000 tax free.
There are no tax consequences of using any amount you happen to have to pay off part of your mortgage.
Make sure you do it right, as some mortgage companies have funny rules about larger payments - they could consider it a 'pre-payment of your next N monthly payments' and as such just 'safekeep it interest free' for you, and pay your monthly rate every month from it. This is obviously bad for you, and not what you want; you want it applied to the principal immediately, so make sure this is what happens.
Overall, no paperwork, and no tax consequences for you. No worries. | Depending on what country the money is coming from, Transferwise might be an option. If they offer transfers out of the county in question it would probably be the cheapest option in terms of transfer fees. If you use a regular bank you are going to get screwed on fees and exchange rate to the tune of 3 to 5% of the amount transferred.
Just have your mother make several transfers under 10k each, no tax consequences.
Also, why on earth would you want pay your mortgage early right now? You can probably negotiate something with your bank, so you don't have to pay anything for a couple of month without any impact on your credit. At the very least, look into refinancing at a lower rate, which you probably can, after the recent rate cuts. |

Redash is our take on freeing the data within our company in a way that will better fit our culture and usage patterns.
Prior to Redash, we tried to use traditional BI suites and discovered a set of bloated, technically challenged and slow tools/flows. What we were looking for was a more hacker'ish way to look at data, so we built one.
Redash was built to allow fast and easy access to billions of records, that we process and collect using Amazon Redshift ("petabyte scale data warehouse" that "speaks" PostgreSQL). Today Redash has support for querying multiple databases, including: Redshift, Google BigQuery, PostgreSQL, MySQL, Graphite, Presto, Google Spreadsheets, Cloudera Impala, Hive and custom scripts.
Redash consists of two parts:
**Query Editor**: think of JS Fiddle for SQL queries. It's your way to share data in the organization in an open way, by sharing both the dataset and the query that generated it. This way everyone can peer review not only the resulting dataset but also the process that generated it. Also it's possible to fork it and generate new datasets and reach new insights.
**Dashboards/Visualizations**: once you have a dataset, you can create different visualizations out of it, and then combine several visualizations into a single dashboard. Currently it supports charts, pivot table and cohorts.
