I have the following code working:  SELECT of_Loans__c, Id, ( SELECT id FROM Loans__r WHERE MtgPlanner_CRM_Status__c = 'Closed')  FROM Contact   After some time tinkering around, I was able to access the information of the loan related list (on the Contact page) using the '__r' extension. The above SOQL query does as I want it:    However, I did this in a sandbox environment which may not have the same relationships between objects as I have in live.  A similar SOQL query (in live):  SELECT of_Closed_Loans__c, Id, ( SELECT id FROM Loans__r WHERE MtgPlanner_CRM__Status__c = 'Closed')  FROM Contact   renders the following error:  didn't understand relationship 'Loans__r' in FROM part of query call. If you are attempting to use a custom relationship, be sure to append the '__r' after the custom relationship name. Please reference your WSDL or the describe call for the appropriate names  Both environments have Contacts with a related list to the Loan object; I do not know what might I need to tweak on the live env. to replicate the results of the successful first sandbox env.   Any suggestions are appreciated!
In Trailhead we have the query to get the Contacts for the Account named "SFDC Computing", with an inner query.   SELECT Name, (SELECT LastName FROM Contacts) FROM Account WHERE Name = 'SFDC Computing'   It works fine for my purposes.  "Contacts" is the name of the relationship, per Trailhead. So, I went to Object Manager and examined the Account object's "Fields and Relationships". There is nothing named "Contacts"!   In general, how do I get the name of the relationship, for use in similar SOQL queries?
The curious case of Dmitri Valtane ProcessStartInfo hanging on "WaitForExit"? Why? I have the following code: info = new System.Diagnostics.ProcessStartInfo(&quot;TheProgram.exe&quot;, String.Join(&quot; &quot;, args)); info.CreateNoWindow = true; info.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden; info.RedirectStandardOutput = true; info.UseShellExecute = false; System.Diagnostics.Process p = System.Diagnostics.Process.Start(info); p.WaitForExit(); Console.WriteLine(p.StandardOutput.ReadToEnd()); //need the StandardOutput contents  I know that the output from the process I am starting is around 7MB long. Running it in the Windows console works fine. Unfortunately programmatically this hangs indefinitely at WaitForExit. Note also this code does NOT hang for smaller outputs (like 3KB). Is it possible that the internal StandardOutput in ProcessStartInfo can't buffer 7MB? If so, what should I do instead? If not, what am I doing wrong? I want to uninstall VMware Player on my Ubuntu 12.04 LTS system. How should I uninstall it? Idiom or expression criticizing people who ignore you right after getting what they wanted/ were after Can I still use logistic regression if some variables are not applied to all the observational units? Some of the variables are questions that are not being asked to every single person in the questionaire depending on how they answered previous question(s). So would I still be able to use a logistic regression if some of the questions (the independent variables) are only measuring the responses of SOME of the respondents? Short story about dead soldiers bodies being reused Since I've a database systems examination in less than 3 hours (from now), I have been browsing Stack Exchange network for questions with normalisation and related tags. Most of the questions are now closed as  or others from the list.  Since, these questions are closed, no users are allowed to post answers to them (unless they are reopened). Why am I, then, allowed the option to protect such questions? Doesn't that beat the entire purpose behind "protecting" a question? When running apt-get -y install &lt;packages ...&gt; on Ubuntu 10.04 I would like apt-get (or aptitude if that makes it easier) to not prompt me when installing additional dependencies (behavior of -y as I understand it) and but not prompt me about overwriting configuration files, instead assume to keep the existing ones always (which is usually the default). Unfortunately --trivial-only seems to be the inverse of -y and not affect the prompt that is shown, according to the man page.  In particular packages auch as samba, nullmailer, localepurge and lighttpd have forced me to interact with the terminal, even though the whole procedure was scripted and meant to be non-interactive. Is taking the CUA (certified Usability analyst) certification worth it? I see a lot of people taking this  nowadays and I wonder if its actually worth it and how is it received by the industry and does it really help in bringing you up to speed with UX and usability best practices. Can anyone who has taken the exam before provide inputs on its benefits and also its cons if any.  I did see the question  and David's answer did mention that he found it useful but I would like to get more context in what sense people might find it useful and how it could potentially supplement or enhance a career. I am having trouble with the following sentence:      "The complexity and diversity of the new platforms is worrying us."   If "complexity" and "diversity" constitute two subjects, then the verb should presumably be "are"; however, the sentence feels more natural with "is". Is this correct? Is there a linguistic term for this occurrence?    The following questions address the general topic of compound subjects, but not specific cases like this:             And the following question seems to have somewhat inconclusive answers:         So this question is not really a duplicate of these three.

Who else knew that Lord Voldemort was Tom Marvolo Riddle? We know that some people were aware of the fact that Lord Voldemort was Tom Marvolo Riddle prior to his return in Goblet of Fire; at the very least his close soon-to-be-Death-Eater &quot;friends&quot; and Albus Dumbledore:  “Very few people know that Lord Voldemort was once called Tom Riddle. I taught him myself, fifty years ago, at Hogwarts...&quot; ... underwent so many dangerous, magical transformations, that when he resurfaced as Lord Voldemort, he was barely recognizable. Hardly anyone connected Lord Voldemort with the clever, handsome boy who was once Head Boy here.” (Professor Dumbledore to Weasleys, Chamber of Secrets, CHAPTER EIGHTEEN, Dobby’s Reward)  and  “Voldemort,” said Riddle softly, “is my past, present, and future, Harry Potter…” He pulled Harry’s wand from his pocket and began to trace it through the air, writing three shimmering words: TOM MARVOLO RIDDLE Then he waved the wand once, and the letters of his name rearranged themselves: I AM LORD VOLDEMORT “You see?” he whispered. “It was a name I was already using at Hogwarts, to my most intimate friends only, of course. ...  (Tom's Diary manifestation in the Chamber of Secrets).  QUESTION: Who - based on canon (books/interviews/pottermore) - knew about the fact that Lord Voldemort was Tom Marvolo Riddle prior to Ginny being taken to the Chamber of Secrets? Obviously, Albus Dumbledore and Tom himself. Who else? My pixel perfect picture gets blurry when compiled in LaTeX How does Ubuntu flavor iso differ from a desktop package? TL;DR: how does an Ubuntu flavor iso installation ( for example Lubuntu ) differ from installing a desktop package via apt-get ? (for instance sudo apt-get install lubuntu-desktop)  Context for the question:   Some time ago I answered a question on AskUbuntu , where I tested in virtual machine removing unity-desktop and installing ubuntu-gnome-desktop. That makes the boot logo ( plymouth ) change, desktop changes, different packages get installed (gnome-network-manager instead of network-manager , if I am not mistaken). It appeared that in effect I've switched to different Ubuntu flavor, even though I started out with the standard Ubuntu system. Hence the question: what differentiates the pre-made Ubuntu flavor iso from installing a package ? Is it all the same base underneath the hood or does installation from iso have specific configurations ? If it's possible to install a flavor via package manager, why then separate flavor iso's exist ? (obvious answer is user convenience, but I think there has to exist other reasons. Canonical is a business , and it makes not a lot of sense for a business to provide additional flavor iso , if a sysadmin or end-user can get the same thing via package manager by themselves). I found a couple useful threads on this forum with respect to the issues posed by (displaying) images in email signatures-- , for example-- and I've searched all over the web, but still have not found a good solution that sufficiently addresses the problem. A client of mine would simply like his company's logo included in the signature of his emails, and the issues I've encountered can be summarized as follows:   I can export a rasterized version of the logo from AI at actual size, and it will look sharp on the desktop but pixelated/blurry on hi-density (e.g. "retina") displays such as the iPhone. As suggested in the thread I referenced, I can export the logo at 2-3 times the actual, displayed size to target the hi-density displays, but the logo will then look soft on non-hi-density displays when it is scaled down. This is a particular problem in this instance as the logo contains text, which looks terrible when juxtaposed with actual text in the browser/email client. I've considered .svg as an option, but apparently the support is not great; and in this case I'm assuming the vast majority of the users reading this client's email will be using Outlook, so something that only renders properly in iOS/webkit/etc is not a viable option.   I'm at a loss at this point and wondering if there is any other possible option out there. I'm not sure, for instance, if it's possible to implement a hi-density image with lo-res fallback in an email signature?  Any suggestions/insights here are much appreciated.
