37,651 | How to get from Langkawi (Malaysia) to Phuket (Thailand) either by ferry, land (train or bus) or by air?
What's the most convenient way?
It seems there are no direct flights and no obvious land routes. | 2014/10/18 | [

] | Please bear in mind that it's a quite long whole day journey.
There are the following option to get from Langkawi to Phuket. I believe the same should work in reverse.
By ferry:
* [Tigerline](http://www.tigerlinetravel.com) (~3300-3700 THB)
>
> Service was launched at the end of 2012. High season route only (operating Nov - April). Check in point located inside the Kuah Jetty (located in Kuah Town) on the Pattaya Beach. Travel Time 10 hrs.
>
>
> Bookings can be made in person at a booth on the pier road in Chalong or by various payment methods over the internet. It appears there is no luggage restriction as there would be when flying. The ferry stops and collects at Koh Lipe (immigration clearance), Trang (30 minute break), Koh Mook, Koh Kradan, Koh Ngai, Koh Lanta, Koh Phi Phi (7 stops in total).
>
>
> The Malaysia Immigration & Customs officials are located inside the jetty. If you do not check-in at least 60 minutes prior to departure, you will not be allowed on board of our ferry.
>
>
> The Thailand Immigration & Customs officials are located on Koh Lipe.
>
>
> Note that if there are not enough passengers, they could cancel or postpone the trip.
>
>

By air:
* Only in-direct commercial flights either by Penang ([FireFlyz](http://booking.fireflyz.com.my/)), Kuala Lumpur (Air Asia) or Singapore (Air Asia). Check [Langkawi Airport](http://www.langkawiairport.com/) for further details.
* Easiest is to fly Langkawi-Penang-Phuket but you have to check schedules work out. If you have extra time in Penang, check the trip to Phi Phi or Khao Lak.
* By [Happy Air](http://www.happyair.co.th/). They operate daily flights between Langkawi and Phuket. They have a little box office at the airport. Flights and office hours are on Mon, Wed, Fri, Sat-Sun. But I'm not sure how this information is reliable. Please contact them for further info.
By land (public transport):
1. Langawi - Satun
* By [Langkawi Ferry Service](https://langkawi-ferry.com/) to Satun (~300THB). It takes around 1,5h.
* By [Tigerline](http://www.tigerlinetravel.com) ferry to Koh Lipe (1200-1400THB), from there to Satun Ferry Port - Pakbara Pier (600-700THB).
* There are also pre-organised “tour” tickets that would pick you from your guesthouse in Langawi and deliver straight to the centre of Hat Yai (~RM 70.00). In total it takes around 7 hours.
2. Satun - Phuket or Krabi (by bus)
As [pnuts](https://travel.stackexchange.com/users/4995/pnuts) mentioned, there is a air-con bus from Satun's bus station to Phuket. Tickets are 400 baht (230 baht to Krabi) and the trip takes about 8 hours.
>
> Satun's bus station is a few kilometres south of town, but buses can be flagged down on Burivanich Road as they leave. Read more at [Travelfish](http://www.travelfish.org/transport/thailand/southern_thailand/satun/satun/all) site.
>
>
>
Or:
2. Satun - Hat Yai
* By taxi, motorcycle taxis or small songthaews.
* By van (on an hourly basis).
* By local bus. It takes around 3-4 hours in total. You can tell the bus driver where you wanted to get off in Hat Yai and he will try to get you as close as he can. It costs around 80 THB.
3. Hat Yai - Phuket
* By direct bus (around 7 hours).
* By train Hat Yai to Surat Thani (for Ko Samui, Krabi). Check [seat61](http://www.seat61.com/Thailand.htm) site for trains details. Then road to Phuket. Surat Thani is about 290km from Phuket. This road journey by bus to Phuket from Surat Thani takes about 5-6hrs.
* By van that goes to Phuket on an hourly basis.
* By air, check the [Hat Yai Airport](http://hatyaiairportthai.com/) site for further details.
By land (by car):
1. By ferry to Satun, from there by car or taxi along the coastal (faster) or inner road.
>
> Along the coastal road, the next major town, after Satun is Trang (Satun to Trang is about 110kms), which is about 320kms (route distance) from Phuket. After Trang is another town called Krabi, which is about 90kms from Phuket.
>
>
>
---
>
> There is the alternative of going to Hat Yai from Satun, about 60kms, then taking a domestic flight to Phuket, via Bangkok; fastest available connecting flights makes this flight journey in about 3 hrs 50 mins(via TG). All other flights e.g. Thai AirAsia, One To Go, Nok Air- also fly into Phuket via Bangkok.

Based on my research there was no simple way to travel between the two islands.
The ferry takes too long and is not a direct service. (I also read on other forums that the journey can get quite unpleasant)
Road takes way too long.
Air was the best option but meant laying over for a couple of hours, and via KL or Bangkok.
I referred to the [Langaki Airport wiki page](https://en.wikipedia.org/wiki/Langkawi_International_Airport) and checked with every airline to coordinate flights, and I was unsuccesful in achieving in an ideal timeframe. |

We are trying to get our Google Drive organised so that the right people get access to the right things without a lot of explicit sharing. We have a top-level folder called "Company" with sub-folders for "Admin", "Finance", "HR", "Engineering" and so on. The sub-folders have more restrictive permissions than the top-level one.
We've now got more or less everything in the right place, and mostly this works. The problem is where individual files or folders have their own permissions - they then don't seem to inherit the permissions from their folders. How do we reset the permissions for *everything* in each part of the hierarchy so they are the same as the parent folder?
On Windows Server or Mac OS X there is a clear distinction between "inherited" and "explicit" permissions for an item, and it is easy to remove the "explicit" permissions for all the items in a hierarchy. Where is this for GD? | 2013/01/07 | [

103,673 | I am trying to understand things like linkers and loaders better.

] | To find out more about linkers, I think they'll generally be discussed in combination with compilers. They are for knitting your various modules together into a cohesive unit, finalizing addresses within that code. Some may even try to perform optimizations.
To find out more about loaders, I think they'll generally be discussed in combination with writing compilers for particular architectures unless you mean loader as a synonym for linker. I'm thinking of the loader as the part of the executable file header that tells the operating system how to open and execute your compiled software.
I agree that reading the Wikipedia articles will probably impart more information than you're looking for. As to where they come into development ... generally they are beyond the control of the project, and are part of the selection of the operating system and the development package you choose to use. It's very rare that you would use (for example) MSVC but want to run a GCC based linker ... might not even be possible. The ONLY place I've ever used a non-standard linker was at IBM when we were using development copies.
If you have more particular, specific questions about these topics, I think you'll find a much better response. | Computers basicly work with binary numbers.
People speak their native languages.
Do, programming languages are for communication between people and computers.
If you say: Add 2 and 3 and then substract 1 from it, I doubt that computer would understand anything (maybe in some programming language it would).
So, you need to translate your source code into a format that computer understands, so you need a compiler, which translates a programming language to co called object code.
But object code is not yet the language a computer understands and executes directly. So it needs a linker which will make an executable file that containts instructions in so called machine language; a machine language is a set of operations coded into binary numbers which processor understands. All binary instructions have its structure and its published by a processor manufacturers. You can look for it on say Intel's site and see how do they look like. |

My company screens all candidates for certain positions. And none for others. I know for a fact that one of my colleagues has all "real" candidates take drug tests. These people are dealing with multimillion dollar FX contracts and one mess up can be devastating.

] | The only way I can think of to modulate the star would be to modify the mechanism used for "[star lifting](http://www.orionsarm.com/eg-article/47897e8b1947c)"
Since you want to induce vibrations in the star, the so called "[huff and puff](https://www.youtube.com/watch?v=pzuHxL5FD5U)" method of star lifting which periodically "squeezes" and "releases" the star using an orbiting magnetic field generator. Rather than using the device in a regular pulsating cycle to pump plasma out of the stellar poles, the pulsations are done in a sequence which imparts information on the regular vibration patterns already existing in the star.
[](https://i.stack.imgur.com/ftgqH.png)
*Star Lifting mechanism*
Given the vast size of a star, the pattern of vibrations will be incredibly slow, and modulating the "squeeze and release" cycle of the star lifting mechanism will most likely have to take place over a period of years even to attempt to imprint information using binary code.
The other issue would be since the astroseismology signals are not obvious, even to a civilization like ours, how do you use this to signal people who are not looking for it? This seems to be a means to send information to your *own* colonies, rather than to send information to the Universe like the Library of Alexandria for all viewers. | Find a neutron star, turn it into an x-ray pulsar
=================================================
First off, no one is going to cause vibrations detectable at light years distance to their own star. Assuming they want their home planet (circling said star) to be habitable, they aren't going to put their planet through a freeze/fry cycle.
[X-ray pulsars](https://en.wikipedia.org/wiki/X-ray_pulsar) release the potential energy of accreted gasses falling to the surface of the (neutron) star giving a continuous x-ray release. As long as the neutron star is spinning with its magnetic axis (where the gas falls) tilted with respect to its spin axis, then anyone looking at the start will see the cyclic appearance and disappearance of of the x-ray beams.
To make this happen, you want to modulate the spin of the pulsar to what you desire. You can do this by accreting mass to the neutron star, which can either increase or reduce angular momentum. The best candidate for accretion mass for modulating and powering your pulsar would be another star, but I suppose a Jupiter or Super-Jupiter would work, just not for as long of a time.
Sure moving a Jupiter (or a star) to a Neutron star isn't the least energy intensive thing you can think of, but it is probably the least energy intensive way to make a galactic scale cyclic transmitter. |

Maybe Inject streams of Muon's in to Sun, it will spedup burning probably for any thermonuclear reaction, and for p-process it may be more efficient as proton have only 1e charge.
This way a Star will be amplifier for your signal, and by focusing beams you may create any distribution of energy and modulate it over time as you wish. Penetration will be maybe up to the star core.
So muon beams get you possibility to use less and get more and have any distribution in outer layers of the star. | Find a neutron star, turn it into an x-ray pulsar

191,703 | We have a three phase power supply (3x25A) at our home in The Netherlands (230V). All three phases are used for an induction cooker, and in parallel, two phases (let's call them 1 and 2) each power about half of the household.
We recently had solar panels installed (about 2.5kWp), and the inverter is tied to the third phase (i.e., not 1 or 2, so it is only directly connected to the induction range). Is this the right way to do it? On the one hand, it seems inefficient to draw most power from phase 1 and 2, and supply power to phase 3. On the other hand, the electrical noise from the inverter is all dumped into phase 3 so perhaps it actually isolates the electrical noise from the rest of the household.
Is there a 'right' way to choose which phase the solar panels are connected to? Or does this squarely fall in the **it really doesn't matter** category? | 2020/05/02 | [

] | Being a grid-tied installation, it's quite possible that the power utility had some say in which phase to connect the PV system to. In 3 phase systems, it's necessary to balance the load as equally as possible between the 3 phases but this is difficult to impossible to do within a single household. So the utility designs the distribution network so that a group of homes share the load across the phases and over a large number, the phases are well balanced.
When connecting PV equipment to their system, generally the utility will provide specific instructions on interconnect based on the capacity and type of your system. You may not have been aware of this as the installer was likely the one receiving the instruction, not you.
You might check with the installer as to the reasons why they hooked it up as they did. | You need to evaluate which phase has the highest average load during the daylight hours and put the system on that. If all your loads were 3 phase (I know they are not) having a single phase solar feed would create imbalances in the system. |

However, its bass notes tend to have an "unmuddier" sound than that of the piano, so there is some sense in playing it as if it were not written transposed.
Similarly, a soprano recorder (flute) tends to be written one octave lower than it is actually played (with tenor recorders (flutes) being written in-pitch if I remember correctly). Again, the sound quality of the piano may make it advisable to play the music as if it were not written transposed.
Music written for piano, however, is always to be played at pitch. The "middle C" C4 between treble and bass clef is pretty much in the middle for pianos. If your piano has a lock, it will be rather close to middle C. |

The idea is that hundreds of thousands of programmers are working on creating a virtual Utopian world all at the same time. In this world they try and solve some of the worlds biggest problems.

That is until a group of hackers start to turn the collective conscience and good will into something much more sinister. Is this idea at least "somewhat" possible?
Meaning can a large group of people could be all coding at the same time in the cloud on the same program? Think of it like creating the code for new sections of World of Warcraft while also playing it at the same time.

59,817 | I live in the United States
Specifically, the state of Colorado.
I am required to tell my new employer what crimes I have pled guilty to, or been convicted of in a court of law.
In Colorado, you can get a ticket for driving a badly damaged car.
If you drive a rust-bucket - a shit-box - then you can get a ticket for having a poorly maintained vehicle. I have done exactly that.
The punishment for this crime crime is a monetary fee + 2 points removed from the guilty party's driver's license.

The answer to your question though is probably **Driving an unsafe vehicle**
[Colorado Revised Statutes Title 42. Vehicles and Traffic § 42-4-202](https://codes.findlaw.com/co/title-42-vehicles-and-traffic/co-rev-st-sect-42-4-202.html#)

A class A traffic infraction is a civil violation.
Note that some driving offenses are crimes: In Colorado, driving more than 25 mph over the posted limit is a class 2 misdemeanor, and doing so in a constriction zone is a class 1 misdemeanor.
Also note that I say probably because it is possible that they charged you with something more extreme- reckless driving? violation of noise or pollution ordinances?- but for a fine small enough that you don't say, 2 points, and you did not have to go to court (you could have if you wanted for the ticket, but not required) it is very unlikely. | Unless you have committed a criminal act such as a hit and run or a crash involving a death, a traffic citation is not a crime crime. If you have received a citation, sometimes known as a ticket, you'll see that signing the citation and paying a fine is not an admission of guilt. You might want to edit out one of the "crime" entries from "crime crime."
The "official name" of the traffic offense will be specific to the traffic statute for which the citation is written. "Badly damaged car" is rather vague and unlikely to be part of the statute. |

12,896 | In Alchemy, the rules for what kinds of cards can replace a trashed card are governed by the following, somewhat ambiguous wording:
>
> Adding coins to a cost doesn't affect [potion] being in the cost or
> not. If [potion] was in the cost, it still is; if it wasn't, it still
> isn't.
>
>
>
The rules then present an example with Remodel card. However, the Remodel card says:
>
> Gain a card costing *up to* two more . . .
>
>
>
The Governor card wording is:
>
> Gain a card costing exactly one (or two [if you're the player playing
> the card]) more.
>
>
>
So, for the player who played the Governor card, it is clear from the remodel example that a card costing exactly 2 coins must be replaced by a card costing exactly 4 coins with no potion.
However, what about a card costing exactly 2 coins and a potion? If trashed, must it be replaced with a card costing exactly 4 coins and a potion? Or could it also be replaced by a card costing exactly 4 coins (but with no potion)? | 2013/09/09 | [

] | It must have a potion. The rule states that any time any cost is increased, the potion quantifier stays. Since the card you are trashing has one potion in the cost, the card you pick up also has to have one potion in its cost. For more strategy with this card (albeit not help with this particular question!) check [this](http://wiki.dominionstrategy.com/index.php/Governor) out. | 'Up to' means you can exchange a card with potion in the cost into a card that does or does not not have a potion in the cost, but you can **not** remodel a card with no potion in the cost into one that does. Remodel says "up to". You may Remodel a Golem into a Gold, or Remodel an Apothecary into a Golem.
If the card says "exactly" like Governor, the card to be gained has to have the same number of potions in the cost, and the specified cost in coins. If you play Governor, you can trash University, and the only possible card you can get in exchange is Golem, as it's the only card that costs exactly 2 more than University. |

I now use the in-ear version instead because they can block out the surrounding noise and therefore allow me to turn the volume much softer - and get a better sound experience as well.
I'm not an audiophile; I know there are much more expensive headsets out there, but €70 is more than enough for my taste. | [White foam covers](http://www.ebay.com/sch/i.html?_nkw=white%20foam%20earbud) might do the trick.

] | When you install a game, Steam set up some registry keys to remember that it already did the first time installation. This step is done when you launch a game for the first time ( when is usually install DirectX and other redistributable needed).
When you reinstall Windows, both the redistributable and the registry is wiped, but since your steam is on a second drive, Steam doesn't need to re-download the games. But when you try to start the game for the first time, it will do the first time installation again, normally setting up anything needed for the game to run. | After installing steam on the C drive, maybe you should copy paste all files from the D directory to the C directory. |

] | 1. The impact on the size of data in bytes is affected by the choice of the Unicode encoding and by the type of data. For example, using UTF-8 (the only useful Unicode encoding on the web), English text has the same size as in 8-bit encodings, except for typographically correct punctuation marks, which may take two bytes each; for Turkish text, any non-Ascii letter is 2 bytes instead of 1 byte; for Russian text, any Cyrillic letter is 2 bytes. In most cases, this does not matter much.
2. Text processing performance depends on what you do and how you do that. The reasonable expectation is that there is no problem worth worrying about. If processing is fast enough, it hardly matters whether it would be 10% faster using an 8-bit encoding.
3. Unicode unification has its impact, but surely Asian languages are not treated all alike. The Unicode standard has a lot to say about specific treatment of characters in Asian scripts and languages. If you are referring to the different shapes of CJK characters in different languages, then the usual solution is to use fonts designed for the language used. (In addition, it can in principle at least also be handled within a font, when OpenType fonts are used.)
Check out the official [Unicode FAQ](http://www.unicode.org/faq/). It has a lot to say about issues like these. | The first two points are very much negligible. You'd need to have a very specific use case where the difference in size and performance make a discernible difference that justifies the headaches of mixed encodings.
Regarding the Unihan characters: They are grouped by meaning of the character, but that character may be written slightly differently in different writing systems. This is a problem of properly marking up the language, it's not really an encoding problem. In HTML documents, you can mark the document with `lang` attributes and/or set specific fonts using CSS which will alter the appearance of the character for the language appropriately. How to handle this correctly depends on the type of software (HTML, desktop app, etc). I'd advise you open a new, detailed question about that. |

Check out the official [Unicode FAQ](http://www.unicode.org/faq/). It has a lot to say about issues like these. | 1. **Increased text size**: Yes. Text size may be increased up to 6 times (for UTF-8). But storage for texts nowadays is nothing a big problem.
2. **Reduction of text processing performance**: As per my opinion, no. An UTF-8 character may take up to 6 bytes, but when scanning thru' the text, and right at the first byte of an UTF-8 character we already know how many bytes more for to read for it (the current character in scanning). So most likely the scanning performance stays the same as O(n), where 'n' is the length of the text. To keep the best performance, try not to access the characters in a text by index (yeah, this is a down-point for performance). Java string is not effected by random index access to string character because Java string is a series of 2-byte characters.
3. **Asian languages treated all alike to the detriment of the national specificities**: Yeah, human languages when presented in text format are all alike, but a letter 'i' of a single stroke or a letter of '長' of 16 strokes is just a character. |

] | Double damage rune just double the base damage + attributes of your hero, and it comes before all other effects/orbs. Lifesteal instead is calculated after all other effects and also after all damage reductions, therefore we can affirm that lifesteal will benefits from a double damage rune.
Regarding Critical Strickes, as described also on [Dota 2 Wiki](http://www.dota2wiki.com/wiki/LifeSteal), they also increase the total amount of life steal per hit. | Short answer is yes.
Practical answer; if you have lifesteal coming from a non orb source (aura, innate ex: lifestealer passive) it is almost always better mathematically to buy Desolator before critical strike against most targets with most armor values you are likely to see in game. |

However, you certainly need a *join table* of Assignments, with fields for:
* PersonID
* JobID
* Date
(this is assuming your rota is daily, otherwise you will need to indicate the shift or hours too). | I think your structure should change on this.
So instead have:
Parent:
ProjectId
Date
PersonId
JobId
Date
Then make the project Id your 'Primary Key' so your parent record.
Then you are just assigning the person, job & date as the child.
That way you can always add to the previous record without relying on date field.
You could then filter via dates etc. |

116,280 | My team and I are developing an enterprise-level application and I have devised an architecture for it that's best described as an "Expression Tree". The basic idea is that the leaf nodes of the tree are very simple expressions (perhaps simple values or strings). Nodes closer to the trunk will get more and more complex, taking the simpler nodes as their inputs and returning more complex results for their parents.
Looking at it the other way, the application performs some task, and for this it creates a root expression. The root expression divides its input into smaller units and creates child expressions, which when evaluated it can use to build it's own result. The subdividing process continues until the simplest leaf nodes.
There are two very important aspects of this architecture:
* It must be possible to manipulate nodes of the tree after it is built. The nodes may be given new input values to work with and any change in result for that node needs to be propagated back up the tree to the root node.
* The application must make best use of available processors and ultimately be scalable to other computers in a grid or in the cloud. Nodes in the tree will often be updating concurrently and notifying other interested nodes in the tree when they get a new value.
Unfortunately, I'm not at liberty to discuss my actual application, but to aid understanding a little bit, you might imagine a kind of spreadsheet application being implemented with a similar architecture, where changes to cells in the table are propagated all over the place to other cells that need the result. The spreadsheet could get so massive that applying multi-core multi-computer distributed system to solve it would be of benefit.
I've got my prototype "Expression Engine" working nicely on a single multi-core PC but I've started to run into a few concurrency issues (as expected because I haven't been taking too much care so far) so it's now time to start thinking about migrating the Engine to a more robust library, and that leads to a number of related questions:
1. Is there any precedent for my "Expression Tree" architecture that I could research?
2. What programming concepts should I consider. I realise this approach has many similarities to a functional programming style, and I'm already aware of the concepts of using futures and actors. Are there any others?
3. Are there any languages or libraries that I should study? This question is inspired by my accidental discovery of Scala and the Akka library (which has good support for Actors, Futures, Distributed workloads etc.) and I'm wondering if there is anything else I should be looking at as well? | 2011/10/25 | [

] | It sounds to me like you've reinvented [Lisp](http://en.wikipedia.org/wiki/Lisp_%28programming_language%29). It has trees of operators and data that get combined into larger and larger expressions. I would suggest you take a look at [Clojure](http://clojure.org). Clojure is a Lisp for the JVM purpose built to tackle functional programming with heavy concurrency from the start. | This sounds like a very good use-case for Clojure. Quick bullets:
* **Functional language** (lazy, impure) - the dominant idiom for creating programs is by composing functions in a very similar manner to your expression trees.
* **Lisp** - as a homoiconic languages it's perfect for code generation and DSLs
* **JVM language** with very easy access to all Java libraries and tools
* **Amazing concurrency features** - [see this video](http://www.infoq.com/presentations/Value-Identity-State-Rich-Hickey)
* **Interactive developemnt** (ability to interact with running program via REPL, redefining objects on the fly etc).
* **Dynamically typed**
Furthermore, you seem to be descibing a [Dataflow Architecture](http://en.wikipedia.org/wiki/Dataflow_architecture). There has been quite a lot of study on such approaches and they are indeed well suited to many domains. If you wanted to implement a distributed dataflow architecture using such "Expression Trees" you might be able to build upon the following:
* Clojure for defining the core expression tree language
* [Storm](https://github.com/nathanmarz/storm) library for distributed processing
* [Incanter](http://incanter.org/) for statistics, data processing and visualisation |
13,037,610 | I'm not a security guru. I'm thinking about how to implement credit card storage in a software system where credit card transactions are accepted through the web, but are manually executed by an in-house user. We are going to use HTTPS which (I believe) will eliminate the risk of a man-in-the-middle attack. Now, I'm trying to figure out if I can make it so that the data received from the client can encrypted before it hits our server.
The idea is that their browser would encrypt the data using the public part of an asymmetric key pair. The private part would be known by an in-house user. Then when it's time to manually process the charge, that user would go to an HTTPS page that we serve. They would manually enter the private key (which would not be transmitted to our servers) and the encrypted credit card info would be retrieved from our system and decrypted by the browser.
In this way I'm hoping I can keep any of our servers from ever seeing unencrypted credit card information. Am I missing some well known security hole? I've read [this](http://www.matasano.com/articles/javascript-cryptography/) which seems to address a different kind of security hole. I've also read a few other SO questions, but none of them seem to map clearly to this particular design.
Edit #1: @Pointy asked why not use the industry standard. Major online retailers use solutions that are far more sophisticated and expensive than my problem warrants. Major retailers automatically process their transactions so typically work toward PCI-DSS compliance. This is not the problem that I'm trying to solve. I'm working on automatic tools to securely assist in manual transaction processing.
Edit #2: @Jason Dean pointed out that I didn't describe the plan for managing the private key very well. The idea is literally to have our employee keep it on a piece of paper at their desk. Our main concern is with remote security violations. Our physical site is secure enough that we're not worried about someone breaking in. The idea would be to keep the private key out of any persistent storage on any machine anywhere that way no purely electronic attack could possibly get both the data and the private key. | 2012/10/23 | [

It would be harder to keep secure and type in (or copy/paste) the private key than it would be to simply type in the credit card number. I would call this a rather obvious mistake in your scheme. Note that security protocols are hard, and as you are "not a security guru" I would strongly discourage you of trying to think one up. | It's interesting that you are so concerned about the unencrypted data being seen by the server, but your willing to give the decryption key for all of that important to whatever $8/hour monkey you decide gets to type (or more specifically copy and paste) asymmetric keys all day.
Where do you plan to store these keys so that your monkey can get to them for copy/pasting? They'll need to be in plaintext for that.
Key management is, without question, the hardest thing to do in cryptography and you are talking about violating best practice protocols by making the key available to users that should not need it and by storing it insecurely.
SSL already takes care of encrypting your data before it leaves the client, then, when it reaches the server, you need to encrypt it again before storing it. You can use asymmetric crypto for that if you really want to. I would not worry about trying to do it at the client.
I think you are making things way harder than they need to be and with no benefit for your effort. |

] | This question is very difficult because meta means a whole lot in different contexts. It is a pretty nuanced idea and very interesting.
In short, meta generally just means "self-referential." Something that references itself is meta; If a character in a TV show says how much his life is like TV, he is "being meta".
Dowd's description of something meta is only sort-of kind-of a-little-bit *meta.* It's more about someone writing what they have experience with.
This word, "meta" is a vaguely casual bit of language that comes from the PREFIX meta, in words such as metaphilosophy, metaphysics, metadata, and metalanguage. It is hard to define this in a way that doesn't make sense unless you already know what it means, so I'll just say: applying the prefix of meta to something means "the study or examination of the thing as a whole."
For example, metaphysics is the philosophy of philosophy. Metadata is data about data. Metalangauge is language for discussing language.
On this website, "meta stack overflow" is a sub-forum where one discusses stack overflow itself. It's a forum about the forums.
It doesn't really mean much of anything; you can just sort of apply it whenever you want to indicate something references itself. | In this case, meta is used to refer to the context and culture surrounding the movie, rather than anything directly portrayed in the movie itself.

However, I don't feel *self-referential* is appropriate here. It's quite different, as the above discussion shows. Modish or not, it seems to be precisely the word that conveys the sense. |
48,174 | Maureen Dowd wrote a review on the recently released movie, “J.Edgar” directed by Clint Eastwood in New York Times November 12 issue under the title, “Dirty Harry meets dirtier Edgar.” Apart from the interest in weird relationship of the FBI’s ‘fearful enforcer’ Edgar Hoover and his protégé, Clyde Tolson, I was caught up with the short phrase, “*It’s sorta meta*,” in the following sentence:
>
> Some F.B.I. agents who worked with Hoover have been grousing that portraying the feared first director of the F.B.I. as homosexual would “turn Dirty Harry into Dirty Harriet,” as William Branon, chairman of the J. Edgar Hoover Foundation, put it.

>
> *It’s sorta meta*: the star who played a fictional law enforcement officer breaking rules for what he sees as the good of society makes a movie about a real law enforcement officer breaking rules for what he sees as the good of society.

Dowd’s articles are always ordeal to me because of inclusion of a lot of unfamiliar words to me and her own style of elocution.
I guess “sorta” means simply “a sort of,” but I don’t understand what “It’s sorta meta” means here. It’s a short phrase, but “meta” is an evasive word for me. I’m not even clear with what “meta user” shown on my page of EL&U page means. Would you explain me? | 2011/11/13 | [

] | In this case, meta is used to refer to the context and culture surrounding the movie, rather than anything directly portrayed in the movie itself. The director, Clint Eastwood, had previously portrayed a law enforcement officer in the movie Dirty Harry. Similar to J. Edgar Hoover, Clint Eastwood's character broke the law for what he saw as the good of society, only P.I. Harry Callahan was a fictional character.
One requires knowledge about the people involved in making the movie, explicitly from outside the context of the movie's plot, to understand this reference, and that's why it's called meta.
Whether or not this is proper usage of the term can be argued. As to this particular instance, I find the comparison a bit of a stretch (the secretive first director of the FBI compared to a practically vigilante PI). | esp. @MikeBrown; @JoelBrown; *Ms* Dowd was indeed using *meta* in the sense explained by Barrie England: "a fictional law enforcement officer breaking rules for what he sees as the good of society" goes on to "...real law enforcement officer breaking rules for what he sees as the good of society".

] | A "focus pixel" is a term Apple coined for camera pixels with a mask placed over half of it to limit the light angles that can reach that pixel ([source](https://techcrunch.com/2018/09/25/see-the-new-iphones-focus-pixels-up-close/)). Comparing pixels with masks on one side against pixels with masks on the opposite side allow for the camera phone to perform passive autofocus via onboard computation ([wiki](https://en.wikipedia.org/wiki/Autofocus#Passive)). Traditionally the number of focus pixels were limited as masking half of the incoming light angles results in noisier signals from those pixels.
However it is likely that developments in noise reduction algorithms (via [neural networks](https://www.cnet.com/news/iphone-11-pros-new-deep-fusion-is-coming-to-boost-your-photos-take-on-google/) and otherwise), [HDR](https://en.wikipedia.org/wiki/High-dynamic-range_imaging), and potentially the sensor itself has resulted in the tradeoff being in favor of more focus pixels which allows for faster, higher resolution autofocus calculations, particularly in low light. | I have not exactly knowledge of that, But I have read some cutting edge of topics on that on below websites which have some following explanation.

] | Study is intransitive in this case and thus cannot be made passive. Only transitive verbs cane be made into passive voice.
>
> I am studied with Mrs. Cara
>
>
>
This implies that someone other than you and Mrs. Cara is studying you and her. It's an unusual sentence but grammatical, but also not the passive form of your original sentence.
>
> I am made to study with Mrs. Cara
>
>
>
This implies someone is causing you to study with Mrs. Cara. It's grammatical, but not the passive version of the original. | "Study" can be *both* an **intransitive verb** (takes one noun, the someone/thing doing the action) or a **transitive verb** (takes two nouns, subject which does the action and object which receives the action)
>
> Active: [someone or something S] **studies** [someone or something O].
>
>
> Passive: [someone or something O] **is studied by** [someone or something S].
>
>
>
As you can see, you just switch the two nouns. In your first answer:
>
> I am studied with Mrs. Cara.
>
>
>
You are the [someone or something O]. Like, say, a police officer is studying *you* to see if you are a criminal. This changes the meaning from your original active sentence, where you were the [someone or something S]. Almost nobody would say this new sentence because the reader of the sentence would certainly be interested in who you are being studied by!
Your second answer:
>
> I[O] am made to study with Mrs. Cara (by my teacher [S]).
>
>
>
Be careful! This is a valid passive construction. However, you are now the object of the verb "made to", something which was not in the original sentence. It works since even though you're the object of "made", you are still understood to be the subject for "study".
To make the pure sentence from active to passive for a transitive verb, you need to make sure you know **both** the [A] and the [B]. What are you studying?
So a pure sentence, where you don't add any unnecessary meaning, looks like this:
>
> Math [B] was studied by me [A] with Mrs. Cara.
>
>
>
You can also optionally drop the [A]. ("by" part)
>
> Math was studied with Mrs. Cara.
>
>
>
This sentence is quite awkward for a native speaker. Most of the time, using the active tense is better.
As a side note, passive voice is impossible with **intransitive verbs** such as to sleep. The only way to make a passive sentence is to do what you did, and change the verb to "make", a transitive verb.
>
> I was made to sleep [by my mother].
>
>
> I was made to study [by my teacher].
>
>
>
Be aware that adding the verb "make" adds extra meaning to the sentence, since it implies someone is influencing you to do it. |

Perhaps...
* Your drones cannot be reliably remote-controlled at great depths?
* Your society needs a reason to keep the growth of the lower classes in check? Compulsory military/mining service fulfills this purpose.
* Drones are simply too expensive? Surely their construction consumes a disproportionate amount of the rare minerals they exist to mine?
* Espionage/sabotage-- foreign corporations hijack/destroy each others' drones? Unless you intend on fully automating undersea warfare and wasting what's left of the resources having robots fling torpedoes at each other, humans are more expendable.
* Putting people to work keeps them out of trouble. You can automate all unskilled labor, but now you have a bunch of bored/desperate people surface-side. Crime increases under these conditions. |

Now, for everyone reaching for the comment button to mention ELF, let's just get it on the table:

1. "Hundreds of meters" doesn't make it to the bottom.
2. That 3-300Hz bit means that the entire, world-encompassing band, has about 300Hz of bandwidth. WiFi has a bandwidth of about 22MHz, or about 73,333 times larger. And you've only got to share it within folks of a couple hundred meters of you.
So plopping some folks on the bottom of the ocean gives you some local human intelligence, without having to maintain a umbilical cord from the bottom of the ocean to the top. If the mining installations lasted for extended periods of time, it might be worth running fiber to them from the coastline, but if they had to roam, that'd be less helpful.
Over shorter distances, you'd have a chance of making things like messenger drones, cables, acoustics, or maybe even light transmit data to the drones. |

or invent something own. Or ask new question on this site ;-) | I agree with much of what Shadowzee has to say about profitability. Modern corporations operate with one thing in mind. Increasing profits for shareholders. Human labor can be VERY inexpensive. It can be the largest cost a business might incur. However there was something Shadowzee didn't mention I don't think. If you look at history governments and business have had little concern with the civil rights of human labor. There are numerous examples. Improved quality of life for working class people is only a fairly recent development. And quite frankly increases in inequality in this country suggest to me that that particular trend has the potential to reverse itself.
What kind of future are you envisioning? A good one...A dark one? If you can think of a scenario which involves coerced unskilled labor you might be able to come up with something along the lines of what I am thinking i.e. some corporate entity viewing the trade-off between expendable low cost unskilled labor and expensive automation that requires AI and coming up with a "unique and inexpensive compromise" - automated human beings with implanted programmable chips to perform the labor of the machines.
There are many people who see the combination of human and machine as a natural part of human evolution (e.g Elon Musk, Ray Kurweil). Corporations might see this as highly beneficial approach to both labor problems, automation problems and what happens if you don't have wage slaves earning money to buy the stuff they sell.
Can't speak to mining the deep sea because I would think this is pretty difficult work and would probably require highly skilled labor rather than unskilled labor. But what about programmable chips to increase the laborer's skill set.
I could see a future where you could have a labor pool that just needs to eat and might
allow themselves to subjected to it. Or forced labor from criminal and political dissident populations.
Sorry...that is a pretty dark scenario but mining industries don't treat their workers very well as a general rule. |

Now, for everyone reaching for the comment button to mention ELF, let's just get it on the table:

1. "Hundreds of meters" doesn't make it to the bottom.
2. That 3-300Hz bit means that the entire, world-encompassing band, has about 300Hz of bandwidth. WiFi has a bandwidth of about 22MHz, or about 73,333 times larger. And you've only got to share it within folks of a couple hundred meters of you.
So plopping some folks on the bottom of the ocean gives you some local human intelligence, without having to maintain a umbilical cord from the bottom of the ocean to the top. If the mining installations lasted for extended periods of time, it might be worth running fiber to them from the coastline, but if they had to roam, that'd be less helpful.
Over shorter distances, you'd have a chance of making things like messenger drones, cables, acoustics, or maybe even light transmit data to the drones. |

Deep sea mineralisation occurs on the sea bed or very close to it, within centimetres. There are no tunnels or holes to dig. Current deep sea exploration programs are targeting mineral deposits that are literally just sitting there waiting for us to pick them up.

Now, to why humans will be very bad for this:
1. There is a reason why the deposits are called deep sea deposits. Because they are *deep*. Like, really ***deep***. Four kilometres deep on average. Developing a submersible that can withhold the immense pressures encountered at these depths is expensive. While there were submersibles that reached deeper depths (up to 12 km), these were specially designed vehicles. Doing this on an industrial scale is simply too expensive. On the other hand, drones don't care about pressure (mostly).
One of the answers commented that:
>
> You could also make humans generally better at identifying mineral veins or using complex tools than drones can (a specialist drone won't have all the tools required to do everything, especially if its meant to be good and cost effective at doing something).
>
>

This is not correct. If you've ever actually seen the deep sea deposits, they look pretty much like the mud around them. The human eye cannot distinguish the good stuff from [gangue](https://en.wikipedia.org/wiki/Gangue). On the other hand, drones can be equipped with instruments such as Raman spectrometers, pXRFs, IR wavelength spectrometers and a variety of other instruments that will be much better than humans in finding the stuff.

We can learn from today's mining industry. [It is gradually becoming more automated with robots](https://www.nbcnews.com/mach/science/robots-are-replacing-humans-world-s-mines-here-s-why-ncna831631). And this is happening in subaerial mines, which are relatively simple to operate. There is absolutely no reason to introduce humans to extreme environments for mining, especially when we already have the technology to do this without humans.

Finally, if interested, the scientific-yet-not-too-technical magazine Elements published a series of articles on deep sea mining in their [October 2018](http://elementsmagazine.org/past-issues/deep-ocean-mineral-deposits/) issue.

This is also the reason space mining is not favored: there are too many places to run and hide once the tech for space colonization exists. | In dangerous places (like outer space, deep sea etc) the only reason to use people instead robots is that in general **people are more flexible and much universal than** single **robot**.
But it's only one side.
Human flexibility reduces in deep sea because of great pressure. Withstand to such pressure much harder that operating in outer space. People should use heavy 'deep' suits even in not-really-deep sea. Even in such deep human couldn't operate by hand but only by specialized instrument **integrated with suite**. But.. you could give this instrument to a robot and direct it remotely! (Robots don't need air and food and it's not a problem to lost some)
Here we could say that remote manipulation requires some reliable communication, calculate costs and go deeper in rabbit hole. But it's out of scope.
So if you really want to get people mining in deep sea *in your world*, you have to **introduce intermediate bases where people would live and operate** nearby drones and do something special which is unreasonable to do on surface. [Repairing drones is an example]
So your question could be reduced to another one: **What benefits to use intermediate inhabited bases?**
Some reasons have been already described (communication and repairing on-site is cheaper). If you look at space programs like ISS or lunar base you probably could add more like
* New technologies
* Proof of national superiority
* Communication with intelligent ~~aliens~~ deep-sea creatures
* Universe exploring and understanding
* Factories which produce not a raw resource but goods with high added value [like engines instead of raw steel]. And those factories couldn't be employed without human *in your world*. [Because in near future it (probably) will be possible in our world]

If the Climate is still in the throes of change, using the surface of the ocean might actually be more expensive than being 30-80m below (ice, storms).

] | Please see the below recommendations regarding your issue with your transactions failing error 5006: Unable to redirect to Vendor's web site. The Vendor failed to provide a RedirectionURL.
The error message itself is not always entirely accurate, as it is displayed when there is any kind of issue with the Notification response they receive in reply to their post to your NotificationURL. The following is a list of various known issues that you can investigate:
1) You can acknowledge receipt of the transaction response with a Status of either OK, INVALID or ERROR
2) Before writing the three fields above to the Response object of the POST, please ensure you clear your response buffer to remove any header code, comments or HTML. The Sage Pay Server is expecting “Status=” to be the first characters in the response. If it does not see these, it treats the response as though it is an error and fails the transaction!
3) Your Notification Page should ONLY respond with a Status field, a RedirectURL field and optionally a StatusDetail field. No other HTML, headers, comments or text should be included either before or after these fields. The Sage Pay Server will treat all such text as an error and fail the transaction
4) Regardless of status, the RedirectURL must be sent that contains a valid, Fully Qualified URL (i.e. an address starting http:// or https://) to the final completion page on your site to which Sage Pay will send your customer
5) Encoding must be as Name=Value fields separated by carriage-return-linefeeds (CRLF)
6) Your notification page on your server may be ‘crashing’ and you should check to ensure that the notification page on your server can handle correctly all the message sent by Sage Pay (OK, ABORT, NOTAUTHED, REJECTED, PENDING and ERROR).
7) You should send OK in all circumstances where no errors occur in validating the Notification POST, so even if Sage Pay send you a status of ABORT or NOTAUTHED, you should reply with an OK and a RedirectURL that points to a page informing the customer that the transaction did not complete.
8) Sage Pay gateway operates on a variety of fixed IP addresses and they usually use separate IP addresses to respond to all transaction requests.
Please ensure that all of the following IP addresses are allowed within your Server or Firewall:
For outbound traffic to our gateway:
195.170.169.9 – live.sagepay.com
195.170.169.8 – test.sagepay.com
For inbound traffic you only need to whitelist IPs if you are using SERVER as this is the only solution that initiates call backs. You don’t need to apply this for our FORM and DIRECT integrations. The IPs from which we call back are:
195.170.169.14
195.170.169.18
195.170.169.15
The Subnet mask used by Sage Pay is 255.255.255.000.
Ensure that your firewalls allow outbound Port 443 (HTTPS only!) and inbound Ports 443 (and optionally 80 HTTP) access in order to communicate with our servers (on Simulator/Test/Live).
There is however always scope for this to change. Sage Pay own the entire 195.170.169.0/255 range (256 IP’s).
9) Are you matching the transaction correctly on your database using the ‘SecurityKey’ we passed to your notification page with the NextURL
10) If the MD5 signatures match, your Notification Script should respond with a Status of OK and a RedirectURL pointing to either an order completion page (if the Status was OK) or an appropriate order failure page (if the Status was NOTAUTHED or ERROR). You may wish ABORT messages to redirect the customer to a page providing them with alternative methods of payment, or asking them why they chose to cancel. If the signatures do not match, you should check that your code is rebuilding the message correctly, and if you are sure that it is, all such messages should be responded to with an INVALID and a RedirectURL pointing the user to a failure page. | Try
