2,185,340 | I've built a simple application in Flex Builder 3 with some trace() calls. It's an "ActionScript Project", no MXML or AIR involved. I don't run the app from within Eclipse, I just open the generated html file with Firefox.
I'm using the Flash Player 10 Debug version. I've correctly set mm.cnf to log trace output, following the official instructions. A flashlog.txt file is generate in the appropriate location.
Despite all that, trace output is not shown in the log file. What am I doing wrong?
(I suspect it's a compiler option, but I can find no such option in the project options in FlexBuilder)
(If I do run the app from Eclipse, by pressing F11, I can see trace output but only inside Eclipse, not in the log file) | 2010/02/02 | [

In the world of software development people dread releasing software with bugs. Naturally, you'll want to release the software without any bugs, but how do you measure "success".
Number of bugs found? -- Team stops reporting bugs, QA finds nitpicky bugs, Dev gets defensive about the process.
Bugs per line of code? -- Introduce lots of lines of code to rig the count even though the extra lines don't do anything.
Ultimately, having the name to put with the human instinct to game a system will probably not help your situation.

Here are two ways to proceed out of many possibilities out there:
1. The moment you changed companies (or the parties that were responsible for your payment changed), your experience with the first ended and that with your second began.
PROS:
This automatically gives you experience with two companies, and that's good.
Also, if your previous employer was large, you can state that on your resume, thereby adding more value than the lesser-known company that made the acquisition.
CONS:
If this happened in a short term, you may be perceived as a job hopper.
**SOLUTION**:
In your description of second company, mention that it acquired your team from the previous one, and then, if possible, list out your achievements/projects post the acquisition.
2. State complete experience as being under the new company. Considering that your team hasn't changed, your experience would have been one continuous stretch from when you began working in the team.
PROS: Continuous experience can be perceived as loyalty. Also, you get to talk about your whole duration of your stay with the team in one shot during your interview, highlighting some of your greatest accomplishments on the team.
CONS: You may be perceived as hiding something, and may goof up if asked about people at company Z before the acquisition.
**SOLUTION**:
Highlight that you were on team X, formerly with company Y, until the acquisition of your awesome team by company Z. You're still in team X, but with Z.
For instance, people who worked in YouTube may now claim to be working with Google, or Alphabet Inc. even though nothing much may have changed about the work they do.
Disclaimer: I am not a lawyer, and this is not legal advice. Your resume is merely a ticket to an interview, which is the real place that you've to impress people. The decision rests with you. So, good luck! |

For whatever reason you chose to concentrate on power consumption. This is fine and I can see at least several reasons for doing so, all perfectly legitimate, but I believe you failed to consider several factors, most important of which is that proper diet is needed to keep humans in more or less healthy condition. And it's not constrained to just physical health. For example, if you'd limit your people to corn you'd [eventually end up with serotonin deficiency and pellagra, which some studies link to Aztec cannibalism, for example.](https://scifi.stackexchange.com/q/111127/39211)
So, depending on the time you plan your group to spend in the closed environment, you have some options, but since vegan diet is very hard to get right without really wide food variety available, you may have to revise your assumptions.
If we're talking about 6 months tops then soybeans or mentioned corn. Soybeans are really good in photosynthesis department, but need to be properly fermented (which takes energy). Corn is also a good choice. But you have to add supplements to it, or introduce more plants, especially vegetables and nuts or oily seeds; though not necessarily a lot.
If you are talking long-term, then without either supplements (vitamins, fats and minerals) or really varied foodstuffs (grains, beans, vegetables, fruits and/or - unfortunately - animals), your group will not survive long.
This means you have to either invest seriously in the area for food production or, which is a better way, introduce plants with much better photosynthesis efficiency (be it breakthrough in cross-pollination or selective breeding or genetic engineering), because then you can get 10 times or 100 times higher yields from area, which you can use for diversified heavily crops or still have room for animals (should you choose so).
Obviously upside of any farming area in closed loop environment is a good way to boost air scrubbing of CO2 and water vapour, so this is a good way to offset energy expenditure there. Also, this whole area may be an excellent place to have for improving all-round wellbeing of the crew. Humans do not do well long-term in enclosed spaces, so having an area that can double as recreational is a benefit. |

] | UV is a poor energy source for agriculture, with enough energy per photon to easily damage living organisms. If you have a source of kilowatts of UV and want to grow crops, you need to convert it to kilowatts of longer-wave light, which can be done quite efficiently with a variety of phosphors. This is in fact how fluorescent lights and most white LEDs work.
Then, once you have light tailored to the plants needs (likely pink or purple in appearance): plants using the C4 pathway are somewhat more efficient at photosynthesis. These include maize, sugar cane, and sorghum, among numerous others: <https://en.wikipedia.org/wiki/List_of_C4_plants>
You will of course produce large amounts of cellulose as well. With the help of the right microorganisms, you should be able to convert that into carbohydrates with more food value for humans or substances of use in your chemical industry, use it to produce plastics and fibrous materials, or just compost it to produce more growth medium for plants. Likely a combination of these. | Most important question to properly answer it is: for how long?
For whatever reason you chose to concentrate on power consumption. This is fine and I can see at least several reasons for doing so, all perfectly legitimate, but I believe you failed to consider several factors, most important of which is that proper diet is needed to keep humans in more or less healthy condition. And it's not constrained to just physical health. For example, if you'd limit your people to corn you'd [eventually end up with serotonin deficiency and pellagra, which some studies link to Aztec cannibalism, for example.](https://scifi.stackexchange.com/q/111127/39211)
So, depending on the time you plan your group to spend in the closed environment, you have some options, but since vegan diet is very hard to get right without really wide food variety available, you may have to revise your assumptions.
If we're talking about 6 months tops then soybeans or mentioned corn. Soybeans are really good in photosynthesis department, but need to be properly fermented (which takes energy). Corn is also a good choice. But you have to add supplements to it, or introduce more plants, especially vegetables and nuts or oily seeds; though not necessarily a lot.
If you are talking long-term, then without either supplements (vitamins, fats and minerals) or really varied foodstuffs (grains, beans, vegetables, fruits and/or - unfortunately - animals), your group will not survive long.
This means you have to either invest seriously in the area for food production or, which is a better way, introduce plants with much better photosynthesis efficiency (be it breakthrough in cross-pollination or selective breeding or genetic engineering), because then you can get 10 times or 100 times higher yields from area, which you can use for diversified heavily crops or still have room for animals (should you choose so).
Obviously upside of any farming area in closed loop environment is a good way to boost air scrubbing of CO2 and water vapour, so this is a good way to offset energy expenditure there. Also, this whole area may be an excellent place to have for improving all-round wellbeing of the crew. Humans do not do well long-term in enclosed spaces, so having an area that can double as recreational is a benefit. |

Then calculate the voltage drop for each stage of voltage divider. | This isn't a direct answer, but if you are trying to figure our the formula, then you could use some kind of simulation software. Build the circuit and add the necessary voltage measurements you consider relevant. Once you add places to measure voltage, run the solver and check the values it outputs. Take note of them and use them as a reference. Work your way through the problem checking the numeric answer against the solver's.
As a side note, only Dwayne's answer is correct. You don't have three simple voltages dividers. Each step is a voltage divider with some cascading parallel resistances. |

] | In 1, below, the two 500 ohm resistors are in series, so they add to an equivalent resistance of 1000 ohms.
That 1000 ohms is in parallel with the 1000 ohm resistor, making the total resistance of the series-parallel network 500 ohms, as shown in 2.
In 2, the 500 ohm net is in series with the 1500 ohm resistor so they add to 2000 ohms. That 2000 ohms is in parallel with the 2000 ohm resistor, making the total resistance equal to 1000 ohms, as shown in 3.
In 3 we have the 1000 ohm net in series with 1000 ohms, creating a voltage divider with an output voltage equal to half of its input, or 3 volts.
In 4. we have redrawn 2, and we can use the 6 volts we got in 3 as the input to the 1500+500 ohm voltage divider, which will give us an output of 1.5 volts.
In 5 we have reconstructed 1, and with the voltage we got from 4 and, as in 4, we can find the voltage originally being sought, which is 0.75 volts.

The problem with "ahead" is when a child lags behind and you don't realize it. And also, you're constantly looking back; which may very well take *your experienced* eyes off of the road ahead.

As for "beside", it'll depend on the road or path situation. Side-by-side riding may or may not be more dangerous, so, you'll have to make a judgement call. On beside, I'd ride beside the less experienced child with the more experienced child ahead. |

] | I follow behind, but some topics need to be reviewed before and during the rides. And also, for all our best intentions, the group gets split, or you coast ahead or they drift behind. I tend to review these points with my family or picnic group:
* The intended route, and I try and ask the kids if they know what and where I'm talking about. It is important to get the kids thinking about their local geography and not mindlessly following mom and dad.
* Marching order: if I'm solo with kids, I'm usually following. If I'm with my wife or another parent, often we have a parent leading, or in second place, and a parent as caboose. Kids that drift left into the lane sometimes need to be placed immediately behind the lead parent to give them a more distinct target to follow.
* Verbally agree, assign or describe the next stop. This not only allows the kids to participate in the navigation, gives them some measured independence towards leading the way, but also is good practice for parents to think ahead about what the next intersection is, and if the kids should lead thru it. Not agreeing on a stopping point leads to kids wandering far ahead parents changing course pursuing kids buddies that just "wanted to check that thing out."
* Leading when you cannot describe the route clearly. Often this is leading slowly, so that the slow pedalers are not left behind. Sometimes traffic is loud, and shouting from behind doesn't work well, so them seeing you lead off can be effective as well.
* If you do lead, lead ahead no more than a block/signal. Sometimes, especially if you are coasting downhill, or your group is split by a changing signal, you have to wait on the other side of the light. I find that on my cargo bike, I end up coasting far faster than the kids can pedal. I've found that I can get caught up in moments of riding just looking at the traffic around you, and suddenly no-one is ahead of you.
* How to handle turning left at a green light. This matter of right-of-way is not intuitive to elementary school kids. Such intersections are important to agree on stopping at, or a block before, and possibly changing your marching order so that you lead when there is a proper break in traffic. | Interesting in that what you describe what you're actually doing seems fine to me.

* The intended route, and I try and ask the kids if they know what and where I'm talking about. It is important to get the kids thinking about their local geography and not mindlessly following mom and dad.
* Marching order: if I'm solo with kids, I'm usually following. If I'm with my wife or another parent, often we have a parent leading, or in second place, and a parent as caboose. Kids that drift left into the lane sometimes need to be placed immediately behind the lead parent to give them a more distinct target to follow.
* Verbally agree, assign or describe the next stop. This not only allows the kids to participate in the navigation, gives them some measured independence towards leading the way, but also is good practice for parents to think ahead about what the next intersection is, and if the kids should lead thru it. Not agreeing on a stopping point leads to kids wandering far ahead parents changing course pursuing kids buddies that just "wanted to check that thing out."
* Leading when you cannot describe the route clearly. Often this is leading slowly, so that the slow pedalers are not left behind. Sometimes traffic is loud, and shouting from behind doesn't work well, so them seeing you lead off can be effective as well.
* If you do lead, lead ahead no more than a block/signal. Sometimes, especially if you are coasting downhill, or your group is split by a changing signal, you have to wait on the other side of the light. I find that on my cargo bike, I end up coasting far faster than the kids can pedal. I've found that I can get caught up in moments of riding just looking at the traffic around you, and suddenly no-one is ahead of you.
* How to handle turning left at a green light. This matter of right-of-way is not intuitive to elementary school kids. Such intersections are important to agree on stopping at, or a block before, and possibly changing your marching order so that you lead when there is a proper break in traffic. |

] | According to [this forum thread](https://forums.mercedesclub.org.uk/index.php?threads/head-bolt-settings-om651-mercedes-c220.142352/), the torque values for the OM651 engine head bolts are as follows:
* 1st pass - 15Nm (11 lb-ft)
* 2nd pass - 90°
* 3rd pass - 90°
I'm assuming these bolts are most likely torque to yield bolts, you need to be using new bolts when you do this. | Had this issue many years ago for an old engine.
The mechanic and I took the bolts and worked out the max allowable loading then took 2/3 of that value.
We also looked at the threads and the material of the head and block then derated that calculated by another 10 or 15%.
The engine ran fine.
Do also consider the head gasket as part of the process - for us is was a copper gasket. |
668,363 | It is possible to access the Windows Store from a remote desktop session and initiate the Windows 8.1 Update from the Windows Store, but the update hangs after the first reboot, likely waiting for the user to accept the license check. This leaves the computer unusable remotely.
Is there a way to pre-accept the license terms so that the update can complete autonomously? Perhaps an UNATTEND.XML such as would be used for an unattended clean install? Failing that, is there a way to connect with remote desktop during that phase of the install (it appears to be GUI-mode setup running with the usual Windows kernel and full OS)? | 2013/11/01 | [

] | On older boards way-back-when which only supported 2GB RAM in total this sort of thing referred to what you would expect to see after on-board video hardware and other devices and consumed some.
On a modern board like this (which supports 64GB as the other specs state) this refers to what memory can be allocated to the on-board GPU - so you might put 8GB in there but only see ~6.25 GB available to OS/apps/games as the GPU has claimed the remainder for its work. You usually have some control over what the GPU does claim, and of course if you completely replace its function with an add-on card (which you likely will if building a machine for gaming) it should take 0.
This information is normally listed with or directly after the name/model of GPU in a specs sheet, I assume that line has been missed out by mistake in this case (either a mistake on the seller's part or due to them copying a bad list from the manufacturer's blurb) leading to a little confusion. | I believe this is related to allocating memory to on-board or on-chip (haswell etc.) GPUs which share system memory. The figure relates to the largest amount of system memory you can allocate across as extra memory for the GPU, in addition to any on-chip or on-board GFX memory. |

] | Check one-time-passwords (OTP). Here's an [example](http://bernard.blackham.com.au/babble/archive/2006/08/OTP_and_SSH.html) | Yes, this is possible. This is exactly the private key authentification over SSH works.
The usual scenario is that the person who wants to log-in receives some kind of "challenge" (this could be a random number, but the current time is also possible if there is some way to ensure synchronous clocks). This challenge is then combined with a secret and the resulting password is sent back. Only if it matches, the person is allowed to log in.
The key authentication just keeps all those things in the background, so you never notice them. If you set a password for a private ssh key, this password will be used for accessing the secret to be combined with the challenge. It will never be transmitted to the other machine, so this is the safest way to use SSH.
This is exactly how those tan generators work in the background. With tan lists it is a bit different. |

In the bid to replace her, Edwin Poots defeated Sir Jeffrey Donaldson by 19 votes to 17 in a vote of party MPs & MLAs on May 14th.
However, just over a month later, Poots resigned as leader after the party refused to support his nomination of Paul Givan as First Minister. In the subsequent leadership election, Sir Jeffrey ran unopposed, and was confirmed as the new leader of the party on June 22nd. | As you might expect in view of their large number of leaders since 2016, this has happened twice with [UKIP](https://en.wikipedia.org/wiki/UK_Independence_Party).
Gerard Batten stood in [2009](https://en.wikipedia.org/wiki/2009_UK_Independence_Party_leadership_election), losing to Lord Pearson of Rannoch, then sat out several leadership contests before being chosen in April 2018.

] | There are a few things to answer here.
First, why do people talk about iconfonts, well they are kinda old news, but the as for the reasons why they're still used they would include:
* Browser backwards compatibility
* Ease of use (especially inline with text)
* Maturity, many existing icon sets come pre-packaged in this form
Second as to the size issue, you can customize icon fonts to include whatever you need specifically, check out [IcoMoon](https://icomoon.io/) (assuming you're not already using an automater such as gulp / grunt). It'll allow you to build / manage your fonts.
Third, i personally don't use icon fonts anymore, because of 2 reasons:
1. They are affected by font anti-aliasing
2. vertical alignment is more difficult (since it's affected by line height, etc)
Instead i use SVG sprites, i also have a nifty gulp process that will let me design in illustrator, and create sprites just by saving them in a particular directory, naturally it also optimizes / compresses them.
If you want to figure out how to do this for yourself i suggest checking out:

337,781 | I have been living under a rock for the past 5 - 8 years, and am just now getting up to speed with virtualization, virtual machines and platforms like VMware or VirtualBox. I *think* I am starting to get them, but there are two concepts about VMs that I'm just choking on for some reason; one has to do with their intrinsic benefit to the enterprise, and the other has to do with their practicality when being used.
So I understand that you can have multiple VMs running on the same physical machine, all doing their own "thing" as if they were separate machines. So let's say I want to make a nice little virtual network of servers in my home office so I can have a big sandbox to play inside of for all my projects. I set up 2 physical machines as servers, and on each of them I have, say, 4 virtual machines running (1 might be an app server, another might be a RDBMS, another might be a message broker, etc.).
1. Besides saving me money (as I only have to provide 2 physical machines instead of buying 8 servers), what instrinsic benefit/purpose do these VMs serve here? I don't care how clever virtual machines are, if my computer only has 8GB of RAM, and I have 4 VMs running on it, those VMs only get 8GB of RAM to share between them. Putting 4 VMs on my server doesn't endow it with 4 times that amount of RAM! *So, as far as I see it, VMs save you money on hardware, but just end up bogging down that hardware as you have multiple machines competing over the same pool of resources.* What am I missing here?
2. Can VMs communicate with each other over your network using high-level protocols like TCP/IP, HTTP, FTP, etc.? Otherwise, it just doesn't make sense to implement all these VMs if you have to feed them separate and independent chunks of data/requests to process. | 2011/09/20 | [

] | **(1) Besides saving me money (as I only have to provide 2 physical machines instead of buying 8 servers), what instrinsic benefit/purpose do these VMs serve here?**
Yes, they do share resources. Virtual Machines are usually allocated a specific amount of memory on startup. So that 8GB could be assigned in 2GB chunks each among 3 machines. (With the last 2GB left so the host OS has something to use.)
Other benefits include save states. Many if not all VMMs allow you to clone a virtual machine, even when "running". So you can clone the state immediately after bootup and should it crash, you can restore it, instead of booting off the crashed system. This can also be used in some cases to save bootup time, as the virtual machine can be restored to the running state.
Another advantage is the ability to swap running VMs between physical machines, allowing 100% uptime even if the host system needs to be taken offline for some reason.
**(2) Can VMs communicate with each other over your network using high-level protocols like TCP/IP, HTTP, FTP, etc.?**
This depends on the VMM you use, and its particular implementation of network emulation. But in general, yes. [VirtualBox](http://www.virtualbox.org/) for example supports emulation of network cards in many ways, including pass-through or NAT. | One benefit of VMs is being able to run legacy operating systems on the latest hardware. Older operating systems (or older versions) may not have drivers available for current hardware. Virtualisation presents the guest OS with virtualised NICs, disk-controllers etc that the guest supports, regardless of the actual hardware.
Another is being able to test new operating systems or application releases separately from live without having to buy as much staging and deployment hardware.
Many of the other benefits boil down to flexibility. Virtual hardware can be resized at will to suit specific tasks whilst preserving the isolation from other applications that you previously got by having separate hardware - if your web database server crashes, it doesn't affect your accounting system.
All the VM systems I know of support networking in the hosted operating systems, there are several modes but for example, the guests can be allocated separate IP addresses in the same range as the host and appear no different to separate physical computers. |

Here are some of the resources you should explore for scientific computing in C++. This is not an exhaustive list, but it should get you going.
* <http://partow.net/programming/exprtk/> ExprTK (easy math expression
library)
* <http://www.vtk.org/> Visualization Toolkit
* <http://qt-project.org/forums/viewthread/22988> Scientific Plotting in
Qt
* <http://qwt.sourceforge.net/> QWT (Qt Plotting Library)
* <http://qt-project.org/downloads#qt-other> (Qt Add-In for Visual
Studio)
Hope that helps. | you should make your hands dirty by trying one of those you prefer.
In my opinion I prefer Qt for C++ programming. And Visual Studio just for C# applications.
one more thing Qt is available in Windows, Linux and Mac. But VS is just for Microsoft OSs. |

16,349 | A [vertical take-off and landing (VTOL)](https://en.wikipedia.org/wiki/VTOL) aircraft is one that can hover, take off, and land vertically. We have several military fighter jets, which can takeoff and land vertically (like the [Harrier Jump Jet](https://www.google.co.in/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&cad=rja&uact=8&ved=0CB4QFjAA&url=https%3A%2F%2Fen.wikipedia.org%2Fwiki%2FHarrier_Jump_Jet&ei=yfCNVeiABYK5uATCpZbQCQ&usg=AFQjCNEcVDkDYsY8R-iKcyFt3rjKyJnpvg&sig2=FrAWGUklPuxSAorRyUSlMg)).
Would it be possible to design an airliner (for example as big as a A320 carrying over a hundred people and travelling at 0.85 mach) to perform VTOL? | 2015/06/27 | [

] | The closest to what you ask was maybe the [Do-31](https://en.wikipedia.org/wiki/Dornier_Do_31) experimental VTOL transport.
Dornier Do-31 in hover. Picture [Source](http://www.diseno-art.com/news_content/2013/10/strange-vehicles-dornier-do-31-vtol-jet-transport/)
It was developed to fly supplies to VTOL fighter bases. Makes no sense to have a VTOL fighter fleet if you cannot supply them, right? That was what the Do-31 was for, and the technically successful program folded when NATO abandoned the VTOL strategy in the Sixties.
Compared to regional airliners of its time, the table below shows how much the installation of sufficient thrust has cut performance:
I used the [Fokker F-28](https://en.wikipedia.org/wiki/Fokker_F28_Fellowship) for comparison, because it is of similar size and age. As you can see, VTOL easily costs half the payload. 36 fully equipped troops may weigh more than 36 passengers, but they will sit on much lighter seats and have much more frugal accommodations. Note that I used the reduced take-off mass for VTOL flight, but have no information if that mass would have included the full payload. The range is valid only for the higher maximum take-off mass of 24.5 tons, for which a conventional take-off was necessary.
The Do-31 could have fitted the Belgian airline [SABENA](https://en.wikipedia.org/wiki/Sabena), which at the time (the Fifties and Sixities of the last century) had the most advanced VTOL strategy of all airlines. They operated [regional connections with helicopters](https://www.youtube.com/watch?v=0sC5jXQZEuA), but eventually reverted to regular aircraft well before the Do-31 would had been available. [Heli-Air Monaco](https://en.wikipedia.org/wiki/Heli_Air_Monaco) is still in operation after almost 40 years, but this is more a taxi service than an airline.
Considering not only the increased fuel consumption, but also the increased maintenance cost on more and diverse engines (most VTOL airplanes have dedicated lift engines), the operating cost even at the times of cheap fuel were too high to make the convenience worth it.
I think it is possible to develop a VTOL A320, but it would look very different, would cruise at a lower speed and have a much reduced payload and range. Tickets would be horrendously expensive, though.
---
EDIT: Thanks to @egid for his suggestion to use mass fractions for comparison. Unfortunately, I found [detailed mass data](https://books.google.de/books?id=V1DuJfPov48C&pg=PA582&lpg=PA582&dq=Fokker%20F-28%20empty%20weight&source=bl&ots=PbzAbzPn4Z&sig=Cep-wOrWf0ED54xpQaDmpUpJZeo&hl=de&sa=X&ei=0HmPVf3BGIPiU5KPruAD&ved=0CFYQ6AEwBw#v=onepage&q=Fokker%20F-28%20empty%20weight&f=false) of the F-28 only for a later version, but the expanded table shows the point clearly:
The useful load fraction is the result of dividing the difference between take-off mass and operating mass empty by the take-off mass, showing the sum of payload and fuel as a fraction of take-off mass. Adding lift engines, slow-speed controls and a rear loading ramp clearly reduced what could be carried in VTOL flight. | A big part of making an aircraft that can take off and land vertically is the thrust to weight ratio has to be greater than 1 so that it can work against the force of gravity. The Harrier Jump Jet can only take off vertically when it isn't loaded to full capacity (in which case STOL is used).
For a commercial airliner to perform VTOL, taking the A320 as an example, it would require more than 765 kN of thrust, which is 3.2 times the thrust it currently has. Such engineering is infeasible with current technology.
* Maximum [A320](https://en.wikipedia.org/wiki/Airbus_A320_family#Specifications) mass is 78 tonnes, so the weight is ~765 kN.
* The two [CFM56-5B4](https://en.wikipedia.org/wiki/CFM_International_CFM56#CFM56-5B_series)'s produce 240 kN. |
1,933 | I am trying to give edit permissions for my partners on a custom object, but on the same time, I need them to have READ only on some of the fields that they see.
The custom object includes a text c\_field that should NOT be edited, but it is visible as read only on the page layout of the partner.
Dongle ID is the field I need as read only.
I want to point that there is NO option to remove the **required** setting from the page layout - I assume this is because the field itself has the isRequired settings

* red star: required field.
Starting with the field property on the page layout shows
 as you can see, the field is required, and the 'read only' CB is greyed out.
How can I change that?

 Indeed, that's what I want to change ^^ - I want to set is as read only.

49,157,966 | I had a test web page that used a restricted SQL user to query an Azure SQL DB to get data from masked fields. It returned the data and it was masked. I rejoiced.
I changed the user with a button and voila! I could see the actual data.
Then today, for some reason, it stopped working and I cried.
I changed no code in between.
I did however use the Azure portal to turn on auditing (can't image that affecting it).
I thought TDE may conflict with DDM but I've read elsewhere that it doesn't - plus it was already enabled when it was working.
I ran a query to show what permissions my "nobody" SQL user had - "connect" only.
So I deleted my "nobody" user and created a new SQL login with associated user (as opposed to just a user). This way I could use SSMS to log in as a restricted user that should be affected by masking - but nope.
So I can setup masks in TSQL or via Azure and Azure shows what's fields have been affected. But I every damned time I run a query in SSMS or via .net I see unmasked data.
I really am stumped so any help would be awesome.
Are there certain circumstances masking would stop working?
Is there anything else I can check to ensure it's setup correctly?

**Japanese** (n): a person from Japan. Ex: *She married a Japanese.*
**The Japanese** [plural] (n): the people of Japan. Ex: *The Japanese make excellent cars.*
**Japanese** (a): belonging to or relating to Japan, its people, or its language. *Ex: the Japanese stock market*

If you catch the exception in some catch statement or it is propagated until main your stack was unwound and you can not expect VC++ to remember the entire stack.
For example in Java stack trace is part of the exception itself. Dependent on you compiler you can write an exception class which records the stack trace if it is constructed (but not copy constructed) and carries the information. When the class is caught you can evaluate the info. If you program using MFC take a look at AfxDumpStack.

Destroing 2 Blocks at a time means that your game registers two hits instead of one.
The first possibilty are corrupted mod files (or a wrong configured fast click mod)
-> check your mods
The second and more propable one would be a changed driver behaviour of you mouse - most likely caused by an installation of another game or software.
-> switch the usb port you are using with your mouse and try again
(i dont think this will be a solution for you, as you got the error on your mouse and touchpad both, but its worth a try)
At last it may be a minecraft caused error.
These occur pretty often if your game crashed anytime before.
It's a little annoying but then you have to delete the folder ".minecraft/versions" in your Appdata folder.
As you wrote a very short question without that much information, i just guess your game is running on a windows machine.
In order to get to your .minecraft folder follow these steps:
1. press [Windows]+[R] (a small window should appear on your bottom left screen)
2. enter "%appdata%" (without the " and a folder should open, called appdata/roaming)
3. scroll this folder until you see another folder called ".minecraft"
4. open it and find the "versions" folder in it
5. delete the "versions" folder NOT the .minecraft folder
6. this does not affect your minecraft maps but your lastlogin file - so just don't mind if you have to enter your password afterwords.
7. at last just start minecraft and log in - you should be done.

Also be sure there is no wax on the window. Some car wash soaps have integrated waxes in them. They are not really a good replacement for a real wax application and they tend to "wax" the windows as well. |

38,324 | If a player passes Go but doesn't ask for their money and the next player plays, does the first player still get their money if they ask only after the next round is played? I could not find this in the Monopoly rules. | 2017/09/04 | [

] | Yes, it's an "accounting" transaction.
Another poster pointed out that the "banker" is supposed to pay the player. Let's say the banker doesn't. (There are only two players, and they're using "honor system" for "banking" transactions.)
The player is "entitled" to his $200 for passing go, and the honor system permits him to take it. In "real life," people sometimes "forget" or delay in collecting their paychecks, but the pay is still real.
Another example: The rules say that there are 32 houses and 12 hotels. Some of them are missing from the set. You use coins or other tokens to make up the difference, so that the game plays fairly. On the other hand, if a 33rd house somehow got mixed in from another set, you should play without it. | thus is what Wikibooks says under “general play” rules for Monopoly...
If the player lands on or passes Go in the course of his or her turn, he or she receives $200 from the Bank. A player has until the beginning of his or her next turn to collect this money. ...There you go! |

] | You can always improve your answer, whether someone downvotes it or not.
As far as removing your answer, yes, you can always delete your answers to get your reputation back, unless it's an accepted answer, in which case you'd need to flag the answer.
People wouldn't really be gaming the system, they would just be getting their points back, which is fine, if the community feels that the answer was so terrible that the total votes on the answer are negative then it's probably better to remove it.
It would help if you linked the answer that was downvoted, then maybe we could give you some hints on how to improve it! | @Jorge 's answer is absolutely correct.
If we're talking specifically about [this](https://askubuntu.com/questions/152727/cannot-use-sudo-from-live-cd/152729#152729) I would examine the comments again.

...normally emphasises the *progressive* nature of the action (i.e. - it didn't happen instantaneously). Per JeffSahol's comment below, in some circumstances it may imply the action was overdue (*should* have happened earlier), rather than that it actually took place over an extended period.
Although it's present tense, people often use *"I notice"* interchangeably with *"I have noticed"* (in respect of something *recently* noticed which you're *now* mentioning).
Thus, for example, *"I came to realise Reagan was a good president"*, implies you only *gradually* realised this. Without the verb *to come*, there's no such implication...

> | "Come to" in these contexts is not a helper verb that changes the tense or mood of the verb that follows. It means to "reach or enter a state, relation, condition, use, or position". The verb that follows, in the infinitive, specifies what that state/relation/etc. is.
So, to answer your questions:
1. When you say "I have come to *X*", it means that you have changed your mind, or your condition has changed, or something else is different that compels you to, or at least suggests that you, *X*.
2. I don't think there is any rule about what verbs could follow. "I have come to run" does not make much sense by itself, at least in the sense of "come" we are talking about right now, but there are sentences where it could work. |

> | *Come to `Vinf`* is a common [Inchoative](http://en.wikipedia.org/wiki/Inchoative_verb) construction.
***Come*** to **be**, in fact, is usually shortened to simply ***become***, and the troublesome word *get* means **both** *come to be* **and** *come to have.* The 4 sentences below all mean the same thing.
* *He came to distrust what they told him.*
* *He came to be distrustful of what they told him.*
* *He became distrustful of what they told him.*
* *He got distrustful of what they told him.*
The difference between a simple Perfect construction (1) and a Perfect inchoative (2)
1. *She has recognized the symptoms in him.*
2. *She has come to recognize the symptoms in him.*
is that in (1) - a [type 3 Stative/Resultative Perfect](https://english.stackexchange.com/questions/63256/which-is-correct-has-died-or-died/63263#63263) - it's the resultant state, his possession of symptoms, that is presently relevant.
Whereas in (2) - a type 1 Universal Perfect - because it's inchoative, it's the continuing (and therefore gradual) **change** of resulting state that's presently relevant. |
