Pass it in environment variables*, or in the content of a file, or pipe it in via a file descriptor.</p> <p>It is possible to modify the command line after a program starts (by overwriting the memory pointed to by argv[1]), but this leaves a window of vulnerability between when the program starts and when its arguments are erased. You cannot avoid this in general. So don't use program command line arguments for any sensitive data.</p> <p>* - The security of environment variables may vary between unixes. On Linux it should be safe - if you have the ability to read env variables, you also have the ability to read process memory directly.</p> |

24,719,063 | 0 | <p>An answer to the revised question. The proper solution for this depends on your page layout, the elements surrounding the h1 and their margins and padding etc. I don't know what your layout is but try these:</p> <p>Either a) Shift the text to the right</p> <pre><code>h1.page-header { padding-left: 20px; } </code></pre> <p>or b) Shift the whole header to the left and compensate by moving the text the same distance to the right</p> <pre><code>h1.page-header { padding-left: 20px; margin-left: -20px } </code></pre> |

9,917,365 | 0 | Experience with using Java EE Restlet's TaskService in an application server? <p>Has anyone used Restlet's TaskService in a Java EE app (deployed in Tomcat, GlassFish, etc)?</p> <p>Is using it going against Java EE's specifications? How does Restlet deal with it when the server/container maintains the thread pool and NOT go against the Java EE spec of not instantiating your own threads in a container managed application?</p> <p>Or are you forced to used Spring and/or interface with CommonJ's WorkManger interface for asynchronous processing?</p> <p>PS: FYI, TaskService basically wraps the ExecutorService of Java 6 - but it's suggested to not used that in an application server context. However, the Java EE version of Restlet does seem to have this service and was wondering if using it would violate the Java EE specs or is a strict no-no or is in fact doable or should one fallback to Spring/CommonJ</p> |

24,958,344 | 0 | <p>By using this package <a href="https://sublime.wbond.net/packages/RegReplace" rel="nofollow">https://sublime.wbond.net/packages/RegReplace</a> you can create regex patterns and bind them to shortcuts.</p> <p>Also if there are multiple occurrences of one word, you can put cursor on whatever part of the word and press CTRL+D multiple times.

10,355,924 | 0 | <p>When you open the exported data file directly with Excel, all formats are set as General. In General format, Excel applies formatting to what it recognizes as numbers and dates. So, to be clear, the issue is not with your export, but rather with how Excel is reading your data by default. Try the following to get around this issue.</p> <p>Export to CSV. Then, rather than opening the CSV in Excel, use Excel's '<strong>Get External Data From Text</strong>' tool to import the data into an empty workbook. Here you can specify to treat this field as TEXT rather than as GENERAL.</p> <p>Note that once Excel applies number (or date) format to a cell, the data in the cell has been changed. No application of a new format will bring back your desired data. For this reason you must specify the format <em>before</em> Excel opens the file.</p> |

21,317,678 | 0 | <p>Not sue why you would need to do this but you can use <code>identical</code> to do the comparison. However, since <code>identical</code> only compares two arguments, you will have to loop over your list, preferably using <code>lapply</code>...</p> <pre><code>lapply( a , function(x) identical( substitute(1 + 2) , x ) ) #[[1]] #[1] TRUE #[[2]] #[1] FALSE </code></pre> <p>Or similarly you can still use <code>==</code>. Inspection of <code>substitute(1 + 2)</code> reveals it to be a <code>language</code> object of length 3, whilst your list <code>a</code> is obviously of length 2, hence the warning on vector recycling. Therefore you just need to loop over the elements in your list which you can do thus:</p> <pre><code>lapply( a , `==` , substitute(1 + 2) ) #[[1]] #[1] TRUE #[[2]] #[1] FALSE </code></pre> |

First, build an index on <code>url, shop, InsertionTime</code>. Then use this query:</p> <pre><code>select ap.* from AllProducts ap where ap.InsertionTime = (select InsertionTime from AllProducts ap2 where ap2.url = ap.url and ap2.shop = ap.shop order by InsertionTime limit 1 ); </code></pre> <p>MySQL does not allow subqueries in the <code>from</code> clause of a view. It does allow them in the <code>select</code> and <code>where</code> (and <code>having</code>) clauses. This should cycle through the table, doing an index lookup for each row, just returning the ones that have the minimum insertion time.</p> |

743,094 | 0 | App_Data/ASPNETDB.MDF to Sql Server 2005 (or 08) <p>I've been developing an ASP.NET WebForms app that needed account login functionality (e.g. register new users, change passwords, recover passwords, profiles, roles, etc). To do this, I used FormsAuthentication with the default data store, which, to my surprise, is an MDF file in App_Data. When it comes time to actually deploy this app. live on the web, I'm going to use some shared hosting like GoDaddy or another cheap company.</p> <p>For efficiency, I'd like to switch over from this MDF to actual SQL Server 2005 or 2008 (who in their right mind uses flat files?). With shared hosting, however, I'm not going to be able to run any programs like aspnet_regsql.exe. I'll just have a single login and password to a SQL Server database, and an FTP account into the domain root.

Hell, I don't even see any connection string to this MDF in the web.config; how the hell is my app. even finding it? Machine.config? That would be a poor decision if that's the case. This behind-the-scenes crap drives me nuts.</p> <p><strong>Any help from someone who has been through this migration would be very, very much appreciated!</strong></p> |

An example where this could occur is double clicking a <code>.py</code> file from the Windows explorer.</p> <p>Typically I use something like the following code snippet, but it has the unfortunate side effect of operating even if the application is invoked from an existing terminal:</p> <pre><code>def press_any_key(): if os.name == "nt": os.system("pause") atexit.register(press_any_key) </code></pre> <p>It's also making the assumption that all Windows users are invoking the application from the Windows "shell", and that only Windows users can execute the program from a location other than an existing terminal.</p> <p>Is there a (preferably cross platform) way to detect if my application has been invoked from a terminal, and/or whether it is necessary to provide a "press any key..." functionality for the currently running instance?

3,186,196 | 1 | Python+Scipy+Integration: dealing with precision errors in functions with spikes <p>I am trying to use scipy.integrate.quad to integrate a function over a very large range (0..10,000). The function is zero over most of its range but has a spike in a very small range (e.g. 1,602..1,618).</p> <p>When integrating, I would expect the output to be positive, but I guess that somehow quad's guessing algorithm is getting confused and outputting zero. What I would like to know is, is there a way to overcome this (e.g. by using a different algorithm, some other parameter, etc.)? I don't usually know where the spike is going to be, so I can't just split the integration range and sum the parts (unless somebody has a good idea on how to do that).</p> <p>Thanks!</p> <p>Sample output:</p> <pre><code>>>>scipy.integrate.quad(weighted_ftag_2, 0, 10000) (0.0, 0.0) >>>scipy.integrate.quad(weighted_ftag_2, 0, 1602) (0.0, 0.0) >>>scipy.integrate.quad(weighted_ftag_2, 1602, 1618) (3.2710994652983256, 3.6297354011338712e-014) >>>scipy.integrate.quad(weighted_ftag_2, 1618, 10000) (0.0, 0.0) </code></pre> |

Typically it looks like this:</p> <pre><code>public class SellerController: Controller { // used to render the form allowing to create a new seller public ActionResult Create() { var seller = new Seller(); return View(seller); } // used to handle the submission of the form // the seller object passed as argument will be // automatically populated by the default model binder // from the POSTed form request parameters [HttpPost] public ActionResult Create(Seller seller) { if (ModelState.IsValid) { listingsDB.Sellers.AddObject(seller); listingsDB.SaveChanges(); return RedirectToAction("Details", new { id = seller.SellerID }); } return View(seller); } } </code></pre> <p>then your view looks as you have shown, it contains a form and input fields allowing the user to fill each property of the model. When it submits the form, the second action will be invoked and the default model binder will automatically fill the action parameter with the values entered by the user in the form.</p> |

So how can I do to take the images from our dev server to our build server ? What is the best way to put it into Team City ?

10,925,210 | 0 | How can I conditionally suppress logging in Express (or Connect)? <p>When using the logger middleware which is part of Connect (as well as Express), I would like to be able to disable logging on certain requests, say by setting a flag on the response or something.</p> <p>I managed to do it by saying:</p> <pre><code>res.doNotLog = true; </code></pre> <p>and then, deep in logger.js (part of the Connect module), I put</p> <pre><code>if(res.doNotLog) return; </code></pre> <p>in the right place.

24,533,397 | 0 | <p>When the server is restarted it loses the connections of all the connected publishers and subscribers just like any other server, so obviously the live stream sources for the hls streams will be gone. The segments themselves only exist up to the maximum segment count per stream, this could be set to some really large number to keep all the segments and thus providing a vod type stream. As the creator of the plug-in, I don't recall if vod is supported out-of-the-box, so you'll have to do a little discovery there. </p> |

8,153,397 | 0 | <p>Tom,</p> <p>I too have been experiencing issues with Sql CE and the Entity Framework. BUT, I may be able to explain the post that you are referencing because I am versed in using it now that I have fought my way through it. </p> <p>For starters, that blog entry was for the MVCScaffolding NuGet package. Not sure if you know what this package does but it basically adds a reference to the Scaffolder that Scott & Company created to dynamically generate CRUD for you once you have built your models. </p> <p>My understanding is that once you create a model, build your project, you can run the following command in the Package Manager Console and it will create the CRUD that I mentioned above.</p> <pre><code>Scaffold Controller [WhateverYourModelNameIs] </code></pre> <p>Now, once this process is complete, it generates a Context class for your application under the Models folder. If you see above in your code (for SQLCEEntityFramework.cs) in the Start method, it mentions that you need to uncomment the last line of the method in order for it to create the db if it does not exist.</p> <p>Lastly, once you execute your application, a SQL CE database "should" be created and if you click on the App_Data folder and choose to 'Show All Files' at the top of the Solution Explorer and hit the Refresh icon, you should see your database.</p> <p><strong>UPDATE:</strong></p> <p>So sorry, after testing this, Tom, you are correct. Only way the database is created is if you execute one of the views that were created by the Scaffolder. </p> |
