28,842,405 | 0 | <p>This is an interesting problem because I googled for many, many hours, and found several people trying to do exactly the same thing as asked in the question.</p> <p>Most common responses:</p> <ul> <li>Why would you want to do that? </li> <li>You <strong>can not</strong> do that, you <strong>must</strong> fully qualify your objects names</li> </ul> <p>Luckily, I stumbled upon the answer, and it is brutally simple. I think part of the problem is, there are so many variations of it with different providers & connection strings, and there are so many things that could go wrong, and when one does, the error message is often not terribly enlightening.</p> <p>Regardless, here's how you do it:</p> <p>If you are using static SQL:</p> <pre><code>select * from OPENROWSET('SQLNCLI','Server=ServerName[\InstanceName];Database=AdventureWorks2012;Trusted_Connection=yes','select top 10 * from HumanResources.Department') </code></pre> <p>If you are using Dynamic SQL - since OPENROWSET does not accept variables as arguments, you can use an approach like this (just as a contrived example):</p> <pre><code>declare @sql nvarchar(4000) = N'select * from OPENROWSET(''SQLNCLI'',''Server=Server=ServerName[\InstanceName];Database=AdventureWorks2012;Trusted_Connection=yes'',''@zzz'')' set @sql = replace(@sql,'@zzz','select top 10 * from HumanResources.Department') EXEC sp_executesql @sql </code></pre> <p>Noteworthy: In case you think it would be nice to wrap this syntax up in a nice Table Valued function that accepts @ServerName, @DatabaseName, @SQL - you cannot, as TVF's resultset columns must be determinate at compile time. </p> <p>Relevant reading:</p> <p><a href="http://blogs.technet.com/b/wardpond/archive/2005/08/01/the-openrowset-trick-accessing-stored-procedure-output-in-a-select-statement.aspx" rel="nofollow">http://blogs.technet.com/b/wardpond/archive/2005/08/01/the-openrowset-trick-accessing-stored-procedure-output-in-a-select-statement.aspx</a></p> <p><a href="http://blogs.technet.com/b/wardpond/archive/2009/03/20/database-programming-the-openrowset-trick-revisited.aspx" rel="nofollow">http://blogs.technet.com/b/wardpond/archive/2009/03/20/database-programming-the-openrowset-trick-revisited.aspx</a></p> <p><strong>Conclusion:</strong><br> OPENROWSET is the only way that you can 100% avoid at least some full-qualification of object names; even with EXEC AT you still have to prefix objects with the database name.</p> <p>Extra tip: The prevalent opinion seems to be that OPENROWSET shouldn't be used "because it is a security risk" (without any details on the risk). My understanding is that the risk is only if you are using SQL Server Authentication, further details here:</p> <p><a href="https://technet.microsoft.com/en-us/library/ms187873%28v=sql.90%29.aspx?f=255&MSPPError=-2147217396" rel="nofollow">https://technet.microsoft.com/en-us/library/ms187873%28v=sql.90%29.aspx?f=255&MSPPError=-2147217396</a></p> <p><em>When connecting to another data source, SQL Server impersonates the login appropriately for Windows authenticated logins; however, SQL Server cannot impersonate SQL Server authenticated logins. Therefore, for SQL Server authenticated logins, SQL Server can access another data source, such as files, nonrelational data sources like Active Directory, by using the security context of the Windows account under which the SQL Server service is running. Doing this can potentially give such logins access to another data source for which they do not have permissions, but the account under which the SQL Server service is running does have permissions. This possibility should be considered when you are using SQL Server authenticated logins.</em> </p> |

20,520,737 | 0 | <p>Although your device is capable of satisfying the usesdevice allocation, without a GPP or other ExecutableDevice, there is no place to run your component. There are two ways that allocation is performed when launching components:</p> <ul> <li>Satisfying usesdevice relationships</li> <li>Deciding on which device to deploy the executable</li> </ul> <p>Each implementation in the component's SPD has a list of dependencies that must be satisfied to run the entry point. Typically, for a C++ component, this will include the OS and processor type. Additional requirements can be defined based on the processing requirements of the component, such as memory or load average; these must be allocation properties known to the target device, just like with usesdevice. There is also an implicit requirement that the device selected for deployment should support the ExecutableDevice interface (there is slightly more nuance to it, but that's by far the most common case).</p> <p>When launching a waveform, the ApplicationFactory tries to allocate all required devices and select an implementation for each component in sequence. Each possible implementation is checked against all of the devices in the domain to see if there is a device that meets its dependencies. If so, the entry point for that implementation will be loaded onto the device and executed, and the ApplicationFactory moves on to the next component. If no suitable device can be found, it throws a CreateApplicationError, as you are seeing.</p> <p>For most cases, you can use the GPP device included with REDHAWK to support the execution of your components. You would usually only write your own ExecutableDevice if you have a specific type of hardware that does not work with GPP, like an FPGA. If you have installed from RPM, there should be a node tailored to your local system (e.g., processor type, Java and Python versions) in your $SDRROOT/dev/nodes directory. Otherwise you can create it yourself with the 'nodeconfig.py' script included with the GPP project; see the Ubuntu installation guide for an example (admittedly, somewhat buried in the REDHAWK Manual, Appendix E, Section 5).</p> |

This results in various problems, like the fact that when I have a JS file that's in the wrong URL, instead of getting a specific error, I get a JS error like <code>unexpected <</code> (same logic is used for <code>404.aspx</code> page).</p> <p>So, to fix this, inside <code>error.aspx</code>, in <code>Page_Load()</code>, I set</p> <pre><code>Response.StatusCode = 500; </code></pre> <p>and the page is returned with 500 status code, which can be observed in the browser.</p> <p>The problem is that if I place a breakpoint inside <code>Page_Load()</code> in <code>/errorpages/error.aspx</code>, it is being hit twice. First time it enters the <code>StatusCode</code> is <code>200</code>, it sets it to <code>500</code>, so my suspicion is that IIS tries to handle that from <code>web.config</code>, it loads the page again. And again the <code>StatusCode</code> is <code>200</code>, and changes to <code>500</code>, but this time it doesn't trigger another execution.</p> <p>This is probably caused by the fact that the exceptions are being handled in Global.asax.cs, where after handling, this is executed:</p> <pre><code>Server.TransferRequest("/errorpages/error.aspx?someExceptionInfo=" + exceptionInfo); </code></pre> <p>So this diagram shows what I think is happening: <a href="https://i.stack.imgur.com/rmT2J.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/rmT2J.png" alt="error workflow"></a></p> <p>I <em>could</em> just set a status code instead of calling <code>TransferRequest</code>, and let IIS handle it, and pass the exception info via the Session. But I'm worried that at some point it might cause some kind of redirect loop or something on Production servers.</p> <p><strong>Question (one of them):</strong></p> <ul> <li>How do I ensure I won't get a redirect loop?</li> <li>How do I configure IIS to make error pages return a status code without actually writing <code>Response.StatusCode = ***</code>?</li> <li>How do I impede my application from repeating execution of the page when I set the <code>StatusCode</code>?</li> </ul> |
34,720,850 | 0 | <p><strong>Why I can't find the file on my device?</strong></p> <p>The file is created successfully but I can't find that on my device because the <code>dataDirectory</code> path which I indicates to create the file, is a private path and my device file manager doesn't have access to it (base on <a href="https://www.npmjs.com/package/cordova-plugin-file#android-file-system-layout">this table</a>). Actually <code>dataDirectory</code> is an <code>Internal Storage</code> option.</p> <blockquote> <p>Internal Storage: Store private data on the device memory.</p> <p>You can save files directly on the device's internal storage. By default, files saved to the internal storage are private to your application and other applications cannot access them (nor can the user). When the user uninstalls your application, these files are removed.(<a href="http://developer.android.com/guide/topics/data/data-storage.html#filesInternal">reference</a>)</p> </blockquote> <p><strong>How to create a public file?</strong> </p> <p>So, to create a file on my device that I can access it with the file manager, I have to use one of public path options like:<code>externalDataDirectory</code>. Before, I was thinking it is for storing files on an external SD Card that I had not on my phone, so I didn't test it. But testing it today, it creates the file on my internal device storage in <code>Android/data/<app-id>/files</code> path which is public and I can access it with device file manager.</p> <p>Actually the term <code>internal</code> and <code>external</code> was misleading for me while <code>external storage</code> can be a removable storage media (such as an SD card) or an internal (non-removable) storage(<a href="http://developer.android.com/guide/topics/data/data-storage.html#filesInternal">reference</a>).</p> |

39,237,567 | 0 | <p>Well according to the <a href="https://www.lua.org/manual/5.2/manual.html#pdf-package.searchers" rel="nofollow">Lua documentation on the require call</a> (using Lua 5.2 here), there are a few places the loader looks for these loadable modules.</p> <p>It seems that <code>require()</code> uses what are called "searchers" (docs linked to in above) to determine where to find these modules. There are four searchers in total. From the docs:</p> <blockquote> <p>The first searcher simply looks for a loader in the package.preload table.</p> <p>The second searcher looks for a loader as a Lua library, using the path stored at package.path. The search is done as described in function package.searchpath.</p> <p>The third searcher looks for a loader as a C library, using the path given by the variable package.cpath. Again, the search is done as described in function package.searchpath. For instance, if the C path is the string <code>"./?.so;./?.dll;/usr/local/?/init.so"</code> the searcher for module foo will try to open the files <code>./foo.so</code>, <code>./foo.dll</code>, and <code>/usr/local/foo/init.so</code>, in that order. Once it finds a C library, this searcher first uses a dynamic link facility to link the application with the library. Then it tries to find a C function inside the library to be used as the loader. The name of this C function is the string "luaopen_" concatenated with a copy of the module name where each dot is replaced by an underscore. Moreover, if the module name has a hyphen, its prefix up to (and including) the first hyphen is removed. For instance, if the module name is a.v1-b.c, the function name will be luaopen_b_c.</p> <p>The fourth searcher tries an all-in-one loader. It searches the C path for a library for the root name of the given module. For instance, when requiring a.b.c, it will search for a C library for a. If found, it looks into it for an open function for the submodule; in our example, that would be luaopen_a_b_c. With this facility, a package can pack several C submodules into one single library, with each submodule keeping its original open function.</p> </blockquote> <p>The searcher of use to us is the third one: it is used for any shared libraries (.dll or .so) which is generally how our custom C modules are built.</p> <p>Using the <em>template</em> string (the one with the question marks), the searcher will look in each of the specified paths, substituting the argument of <code>require()</code> in place of the question mark. In order to specify the path for this third searcher, one must set (or append to) <a href="https://www.lua.org/manual/5.2/manual.html#pdf-package.cpath" rel="nofollow"><code>package.cpath</code></a> and then call <code>require()</code>.</p> <p>So perhaps you have a directory structure as</p> <pre><code>- ROOT |-lua |-bin </code></pre> <p>where <code>lua</code> contains <code>script.lua</code> and <code>bin</code> contains <code>mylib.so</code></p> <p>To load <code>mylib.so</code>, you just need these two lines of code in <code>script.lua</code>:</p> <pre><code>package.cpath = '/ROOT/bin/?.so;' .. package.cpath libfuncs = require('mylib') </code></pre> <p>NOTE: Notice the semicolon. If you append (as opposed to the prepending above), make sure to lead with the semicolon on your added path. It is not there buy default. Otherwise your new path will be merged to the current default cpath, which is just <code>./?.so</code>.</p> |
11,431,333 | 0 | <p>Here is an example. Suppose we have 2 classes:</p> <pre><code>class A { public String getName() { return "A"; } } class B extends A { public String getName() { return "B"; } } </code></pre> <p>If we now do the following:</p> <pre><code>public static void main(String[] args) { A myA = new B(); System.out.println(myA.getName()); } </code></pre> <p>we get the result</p> <pre><code>B </code></pre> <p>If Java didn't have <code>virtual method invocation</code>, it would determine at compile time that the <code>getName()</code> to be called is the one that belongs to the <code>A</code> class. Since it doesn't, but determines this at runtime depending on the actual class that <code>myA</code> points to, we get the above result.</p> <p><strong>[EDIT to add (slightly contrived) example]</strong><br> You could use this feature to write a method that takes any number of <code>Object</code>s as argument and prints them like this:</p> <pre><code>public void printObjects(Object... objects) { for (Object o: objects) { System.out.println(o.toString()); } } </code></pre> <p>This will work for any mix of Objects. If Java didn't have <code>virtual method invocation</code>, all Objects would be printed using Object´s <code>toString()</code> which isn't very readable. Now instead, the <code>toString()</code> of each actual class will be used, meaning that the printout will usually be much more readable.</p> |

30,627,194 | 1 | Understanding control flow of recursive function that uses splicing <p>I seem to be unable to understand why it is, that once the terminating base condition is met in a recursive function, the function continues to call itself and go back up the call stack. </p> <p>Here's an example recursive function written in Python 2.7:</p> <pre><code>text = "hello" def reverse_string(text): if len(text) <= 1: return text return reverse_string(text[1:]) + text[0] </code></pre> <p>Using the <a href="http://www.pythontutor.com/visualize.html#mode=edit" rel="nofollow">Python visualizer</a>, I understand how as the function calls itself with <code>reverse_string(text[1:])</code> and each frame is created as follows: </p> <pre><code>Frames Global frame text "hello" reverse_string reverse_string text "hello" reverse_string text "ello" reverse_string text "llo" reverse_string text "lo" reverse_string text "o" Return value "o" </code></pre> <p>My question is this: why when the base condition is met (when <code>text = "o"</code>) does that trigger text[0] to start operating? I was thinking that all the code on that return statement/line would be working together at the same time, not understanding why <code>reverse_string(text[1:])</code> happens first, then <code>text[0]</code> — and again, why is <code>text[0]</code> activated when the base conditional is met?</p> |

24,542,886 | 0 | Starting eclipse from Command Prompt different than double clicking <p>My university wipes their public computers every time someone logs off, so I have decided to write a .bat file that copies my eclipse from a flash drive to their desktop with all my code intact. The file currently looks like this:</p> <pre><code>@echo off mkdir C:\Users\lib-pac-olin-ppc\Desktop\eclipse xcopy eclipse C:\Users\lib-pac-olin-ppc\Desktop\eclipse /S /E C:\Users\lib-pac-olin-ppc\Desktop\eclipse\eclipse.exe </code></pre> <p>When I run this, eclipse starts up but behaves as if it has been launched for the first time. It does not adopt the default workspace settings and it flashes up the welcome screen. However, when I launch eclipse by directly double clicking it, it goes to my workspace and pulls up my code. It also launches a lot faster. Why is this happening?</p> <p>For the person that asked, here is the .ini file:</p> <pre><code>-startup plugins/org.eclipse.equinox.launcher_1.3.0.v20140415-2008.jar --launcher.library plugins/org.eclipse.equinox.launcher.win32.win32.x86_64_1.1.200.v20140603-1326 -product org.eclipse.epp.package.standard.product --launcher.defaultAction openFile --launcher.XXMaxPermSize 256M -showsplash org.eclipse.platform --launcher.XXMaxPermSize 256m --launcher.defaultAction openFile --launcher.appendVmargs -vmargs -Dosgi.requiredJavaVersion=1.7 -Xms40m -Xmx512m </code></pre> <p>I should note that the JVM was placed in a folder called jre within the eclipse directory, which is where eclipse looks for it by default.</p> |

11,665,548 | 0 | Implementation details of MPI collective operations on a multi core machine <p>In MPI, each rank has a unique address space and communication between them happens via message passing. I want to know how MPI works in a multicore machine which has a shared memory. If the ranks are on two different machines with no shared memory, then MPI has to use messages for communication. But if ranks are on the same physical machine (but still each rank has a different address space), will the MPI calls take advantage of the shared memory. Say for example I'm issuing an ALLREDUCE call. I have two machines M1 & M2 each with 2 cores. Rank R1, R2 are on core1 & core2 of machine M1 and R3&R4 are on C1&C2 of machine M2. How would the ALLREDUCE happen. Will there be more than 1 message transmitted? Ideally I would expect R1&R2 to do a reduce using the shared memory available to them (similarly R3&R4) followed by message exchange between M1 & M2. Is there any documentation where I can read about the implementation details of the collective operations in MPI?</p> |
