So how would one go about retrieving the options from a multi picklist?  I have a custom picklist field which has several options to choose from. Just to be clear, I'm talking about the options of that field, not the values chooses by a user.     Choose fav. car brand:         audi   bmw   vw   mercedes      The brands (bmw, vw, etc.) are the options I'm talking about.  I'm using PHP so the answer im looking for should be a SOQL syntax.
I have a Student object and have a pick list field  "Student Status" in this object. Status can be Full-Time OR Part Time. Now my requirement is i want this student status list, Part-Time or Full-Time in apex controller. how can i do this?  If i get a student record it will only give me that particular student status Full-Time or Part-Time. But i need all options that are available in student status field.  Please help me
Intuitively, why does (B → S) ≡ (¬B ∨ S)? I pursue only intuition; please do not answer with  or . I comprehend the following explanation, but it still does not supply the intuition and I sense a deeper, directer, more intuitive explanation. So how else can I intuit this? Or have I neglected something below? I rewrote: p 51-52.  (2010 2 ed) by Henle, Garfield, Tymoczko.    If the kid misbehaves and the teacher forces him to stay, then the teacher spoke truthfully. Suppose the kid misbehaves but travels. Then clearly the teacher lied. But what if the kid misbehaves, but a big snowstorm forces the trip’s cancellation? You can’t say the teacher lied. The kid behaved but didn’t go; nobody went. The teacher spoke truthfully. 1. If the kid behaved and travels, the teacher spoke truthfully.  Notice that the pattern of Ts and Fs we get, is the pattern for disjunction (see p. 38). What are the pros and cons of having a separate home partition? align xticks in PGFPlots The text xticks are not placed on the same line, rather the same height counting from the highest letter (zero is much higher than high and low).

Further, the partition will need to be resized from WITHIN windows, because you will have this empty space:    I was able to resize the partition easily using a bit of freeware called . What is the best way to store user settings for a .NET application? I have a .NET 2.0 Windows Forms application. Where is the best place the store user settings (considering Windows guidelines)?  Some people pointed to Application.LocalUserAppDataPath. However, that creates a folder structure like:     C:\Documents and Settings\user_name\Local Settings\Application   Data\company_name\product_name\product_version\   If I release version 1 of my application and store an XML file there, then release version 2, that would change to a different folder, right? I'd prefer to have a single folder, per user, to store settings, regardless of the application version. ­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­ How can I take a picture with my webcam in Windows 7?

AuraClientService.postProcess: error in processing [RangeError: Maximum call stack size exceeded] - Client Side Action I have a lightning component that is using ui:inputSelect.   The component code:              &lt;div class="slds-form-element__control"&gt;                 &lt;ui:inputSelect class="slds-select" aura:id="quals" change="{!c.getPreCodes}"&gt;                     &lt;aura:iteration items="{!v.questions}" var="q"&gt;                          &lt;ui:inputSelectOption aura:id="question" text="{!q.Id}" label="{!q.Question_Text__c}"/&gt;                     &lt;/aura:iteration&gt;                 &lt;/ui:inputSelect&gt;             &lt;/div&gt;   The controller:      getPreCodes : function(cmp, event, helper){         var selected = cmp.find("quals").get("v.value");          var action = cmp.get("c.getPreCodes");         action.setParams({             "qualID" : selected         });         action.setCallback(this, function(response){             var state = response.getState();             if (state === "SUCCESS") {                  console.log('precodes: ', response.getReturnValue());              }         });          $A.enqueueAction(action);     }   The basic logic is that the uiSelect is dynamically populated on init (this works fine). When a user makes a selection the "change" parameter function is fired to retrieve a list from the database and pass it to another component.   However, the change function {!c.getPreCodes} seems to be called recursively causing a      "Something has gone wrong. AuraClientService.postProcess: error in   processing [RangeError: Maximum call stack size exceeded] . Please try   again."   error. If I comment out the enqueueAction the function only runs once (nothing is called recursively) so I suspect it has something to do with the controller call. Let $\gamma:[0,1] \to \mathbb R^n$ be a smooth closed curve, such that $\gamma(0)=\gamma(1), \gamma'(0)=\gamma'(1), |\gamma'(a)|=1$ and let $B_r=\{x| \exists t, |\gamma(t)-x|&lt;r\}$. How can i show that the volume of $B_r$ is equal to $br^{(n-1)}$ for $r &lt;\varepsilon$ for some $\varepsilon&gt;0$. And how can I find $b$? It is intuitively obvious. But how can one prove it? I have no idea. Few days back I have installed ecryptfs, created a private directory using it. Now my Ubuntu login became super slow. I have tried removing ecryptfs from Synaptic. I found It, it can not be deleted that way. Somewhere I have read about this command  ecryptfs-setup-private --undo   But this command displays a rather confusing list of commands on terminal. I don't want to mess up my installation, neither want to loose my administrator account.  Now my question is, how can I safely remove /home/user/Private (.Private) and remove ecryptfs encryption ? I know that $re^{i\theta} = x + iy$ for any complex number $x + iy$ by Euler's formula. How do you calculate relative and global phase? I found  where a technician with a lot of experience seems to clean his PCBs using water, and then he just puts it in the sun so it can dry. I was just amazed to see the circuit keeps working as intended, he says he keeps doing this all the time and several times, however I doubt this is normal.  Which leave me some questions:   What are the recommended methods to clean huge PCBs like the one in the video? What happens to charged capacitors when water shorts them out? Solder joints do not get any kind of corrosion? Is the antisolder mask waterproof? date command not resolving properly in bash alias How do I uninstall Ubuntu Wubi? I was trying to give the wording "isomorphic groups have the same structure" a precise interpretation, at least for the finite order case. A positive answer to my final question would reach the goal, as it would translate a "$\cong$" between groups into a "$=$" between sets.    For $n$ positive integer, let be:   $I_n:=\{1,\dots,n\}$; $G$, $\overline G$ groups of order $n$; $\psi\colon G \rightarrow \overline G$ isomorphism; $f$, $\bar f$ bijections; $\theta$, $\bar \theta$ embeddings; in general, $\varphi^{(\alpha)}$ the isomorphism between symmetric groups on sets of the same cardinality, defined by $\sigma \mapsto (g \mapsto (\alpha\sigma\alpha^{-1})(g))$, where $\alpha$ is a bijection between the sets; $S_n$ the symmetric group of degree $n$.

Magnitude of standardized coefficients (beta) in multiple linear regression Being aware of , I am curious about the question how big standardized coefficients can get. I had a discussion with my professor about that issue and she was arguing standardized coefficients (beta) in multiple linear regressions can not become greater than |1|. I have also heard that predictors with standardized coefficients greater than 1 should not be be included/appear in multiple linear regression. When I recently estimated a multiple linear regression in R using lm(), I estimated the standardized coefficients with lm.beta() function from the package 'lm.beta'. In the results I could observe a standardized coefficient greater than one. Right now I am just not sure about what is the truth.  Can standardized coefficients become greater than |1|? If yes, what does that mean and should they be excluded from the model? If yes, why?  I would be very thankful, if somebody could make this issue clear for me. How to create a SQL Server function to "join" multiple rows from a subquery into a single delimited field? Are the proofs for the properties of parallel lines, and that a triangle has 180 degrees, inherently tautological? I've noticed something while trying to prove the properties of parallel lines, and the properties that a triangle has 180 degrees. To prove the properties of parallel lines, such as alternate angles, you need to use the property that a triangle has 180 degrees. To prove a triangle has 180 degrees however, you need to use the properties of parallel lines. This really bothers me because of how circular it is. They are both reliant on each other to be true, and do not logically show, without being reliant on each other, why triangles have 180 degrees, and why parallel line properties are true.   So what I hoping for here is a way to prove parallel line properties without using the fact that a triangle has 180 degrees, or a way to prove triangles have 180 degrees without using parallel line properties. This way, things will be logical to me, and make sense.   Thanks in advance. Which movie/TV show has an evil cyborg harvesting eyes from androids in a hidden town? I watched it maybe more than 8 to 12 years ago, but as far as I remember there was this place where androids (or maybe they were cyborgs) lived. (I think it was more like a hidden town). This guy finds them by accident (or at least I remember it that way) and tries to help them. I don't remember seeing any aliens or spaceships or anything like that. It was live-action, and I think US-based.  So, what I remember:   The bad guy is a human who has one red flashy robotic eye (not like terminators, it looks like a square eye patch above one of his eyes that functions like a second eye), he is collecting eyes from these androids/cyborgs. He also kills some of these androids/cyborgs but not all of them, some of them he just collects their eyes and doesn't kill (or get to kill). There was this woman who was a sexbot or something, she tried to give pleasure to the bad guy at some point, yet the bad guy added one of her eyes to his collection instead, but didn't/wasn't able to kill her. Towards the end she says something like "I used to give pleasure, now I only want to give pain" The human guy who found them tried to help them defend themselves from the bad guys, but they were in bad shape, many of them needed repair. To repair some of them, they needed spare parts they didn't seem to have, but one of the android/cyborg dudes said something like "we don't really bury our dead" and he brought a box of spare parts (or maybe android/cyborg body parts), they used these parts to repair some of the androids/cyborgs. There was this android/cyborg guy who was an assassin or something, but lost his fingers or hands, they couldn't find any hands compatible to his, but he said something like "I can still feel my trigger finger, just attach the weapons to my hands".   I remember it as a great movie/tv show, but I can't find anything about it. Can someone help me?  Please and thank you in advance...
