40,813,220 | 0 | PHP open source multi user login <p>I've had, I believe, a great business idea so I’ve decided to try develop a minimum viable product myself.</p> <p>A long, long time ago I taught myself asp classic and built a couple of apps so I have some development experience. I haven't done much since (apart from a few basic php sites for friends) and I'm not a natural coder though and find it quite hard going.</p> <p>Bearing this in mind and considering the importance of proper security I'm trying to give myself a head start so have been looking for an open source (or paid if it’s not too much) PHP single-db multi-tenant framework or site template.</p> <p>The idea I am working on is aimed towards very small businesses and in a nutshell:</p> <p>User A should be able to login and add and retrieve data that only he/she can see. User B should be able to login and add and retrieve data that only he/she can see.</p> <p>It’s pretty standard stuff but as far as I can tell, everything I’ve found so far is aimed towards managing multiple users across a single secure area (e.g. User Frosting) rather than multiple users across their own secure areas </p> <p>Does such a template/framework exist?</p> <p>Alternatively, can somebody recommend a PHP framework that’s good for beginners with a decent supply of starter templates/tutorials? Innomatic keeps cropping up in my searches but I fear that it may be more advanced and more “full-featured” than necessary.</p> <p>Any advice, opinions or pointers towards relevant material would be massively appreciated.</p> <p>Thanks</p> <p>Stu</p> |
39,281,786 | 0 | jQuery change css background when y-axis scroll reaches a certain depth <p>After scrolling down 600px, I would like a css background-image to appear from no image to a decided background-image (image 1); however, above 600px, I would like to change to another image (image 2).

40,159,956 | 0 | Azure Service Bus: Which message type? <p>I'm going to write an app under Xamarin for iPhone/Android/WindowsPhone that gets continuus data from a server and also sends back continuus data (~ every 10 seconds). I'm going to use Microsoft Azure. I've found that the service bus could help me. What type of messages (relay / brokered) should I use?</p> <p>Imagine a service where you see the actual traffic situation. Every client sends it's anonymous traffic data to the server and it sends the state back to all receivers.</p> <p>I've viewed <a href="https://azure.microsoft.com/en-us/documentation/articles/service-bus-relay-tutorial/" rel="nofollow">this tutorial too</a>, ist says</p> <blockquote> <p>The main difference between a WCF and a Service Bus service is that the > endpoint is exposed in the cloud instead of locally on your computer.</p> </blockquote> <p>What does this mean? I need an endpoint locally on a smartphone. Is this usable?</p> <p>I've read <a href="https://azure.microsoft.com/en-us/documentation/articles/service-bus-messaging-overview/" rel="nofollow">this article</a>. I understand that for relayed messaging, both sender and receiver have to be online and it's a centralized (star-topology) communcation model. That would conver my needs. What confuses me is the word "relay". Does it mean, the messages are repeated somehow?</p> <p>The brokered messages don't fit what I want becaus in my case it's irrelevant for the receiver if it is offline. The messages don't have to be stored.</p> |

11,043,170 | 0 | <p>I would also recommend sugarCRM because of the larger community and availability of third party plug ins, having worked with both i can say that sugarCRM's studio gives you a bit more flexibility. There are also many plug ins; I would recomend the ModernAqua theme to improve look and feel.</p> <p>I'll give you a warning however, sugarCRM is not always nice to work with. Its code is poorly documented and maintainance is a big hastle. upgrading with custom code is still error prone through version 6.x despite what they say and changes will be overwritten by the module builder.</p> <p>So in short, go with Sugar but think carefully before customizing it too much because it can be a pain to maintain.</p> |

22,035,915 | 0 | How to specify the number of parallel tasks executed in Parallel.ForEach? <p>I have ~500 tasks, each of them takes ~5 seconds where most of the time is wasted on waiting for the remote resource to reply. I would like to define the number of threads that should be spawned myself (after some testing) and run the tasks on those threads. When one task finishes I would like to spawn another task on the thread that became available.</p> <p>I found <code>System.Threading.Tasks</code> the easiest to achieve what I want, but I think it is impossible to specify the number of tasks that should be executed in parallel. For my machine it's always around 8 (quad core cpu). Is it possible to somehow tell how many tasks should be executed in parallel? If not what would be the easiest way to achieve what I want? (I tried with threads, but the code is much more complex). I tried increasing <code>MaxDegreeOfParallelism</code> parameter, but it only limits the maximum number, so no luck here...</p> <p>This is the code that I have currently:</p> <pre><code>using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; namespace ConsoleApplication1 { class Program { private static List<string> _list = new List<string>(); private static int _toProcess = 0; static void Main(string[] args) { for (int i = 0; i < 1000; ++i) { _list.Add("parameter" + i); } var w = new Worker(); var w2 = new StringAnalyzer(); Parallel.ForEach(_list, new ParallelOptions() { MaxDegreeOfParallelism = 32 }, item => { ++_toProcess; string data = w.DoWork(item); w2.AnalyzeProcessedString(data); }); Console.WriteLine("Finished"); Console.ReadKey(); } static void Done(Task<string> t) { Console.WriteLine(t.Result); --_toProcess; } } class Worker { public string DoWork(string par) { // It's a long running but not CPU heavy task (downloading stuff from the internet) System.Threading.Thread.Sleep(5000); return par + " processed"; } } class StringAnalyzer { public void AnalyzeProcessedString(string data) { // Rather short, not CPU heavy System.Threading.Thread.Sleep(1000); Console.WriteLine(data + " and analyzed"); } } } </code></pre> |

2,090,043 | 0 | <p>I think what you want to customize is <code>compilation-parse-errors-filename-function</code>, which is a function that takes a filename, and returns a modified version of the filename to be displayed. This is a buffer local variable, so you should set it in each buffer that will be displaying python errors (there is probably an appropriate hook to use, I do not have python mode installed so I cannot look it up). You would use <code>propertize</code> to return a version of the input filename that acts as a hyperlink to load the actual file. propertize is well documented in the elisp manual.</p> <p>If compilation-parse-errors-filename-function is not getting called, then you want to add a list to <code>compilation-error-regexp-alist-alist</code> (that does say alist-alist, that is not a typo) which is a list of mode names followed by regular expressions to match errors, and numerical indexes of the matching line number, filename etc. info in the error regexp match.</p> |

25,480,922 | 0 | bash: wait for specific command output before continuing <p>I know there are several posts asking similar things, but none address the problem I'm having.</p> <p>I'm working on a script that handles connections to different <code>Bluetooth low energy</code> devices, reads from some of their handles using <code>gatttool</code> and dynamically creates a <code>.json</code> file with those values.</p> <p>The problem I'm having is that <code>gatttool</code> commands take a while to execute (and are not always successful in connecting to the devices due to <code>device is busy</code> or similar messages). These "errors" translate not only in wrong data to fill the <code>.json</code> file but they also allow lines of the script to continue writing to the file (e.g. adding extra <code>}</code> or similar). An example of the commands I'm using would be the following:</p> <pre><code>sudo gatttool -l high -b <MAC_ADDRESS> --char-read -a <#handle> </code></pre> <p>How can I approach this in a way that I can wait for a certain output? In this case, the ideal output when you <code>--char-read</code> using <code>gatttool</code> would be:</p> <pre><code>Characteristic value/description: some_hexadecimal_data` </code></pre> <p>This way I can make sure I am following the script line by line instead of having these "jumps".</p> |

20,789,852 | 0 | <p>Because layouts are typically constructed from left to right, it is common for the right side of the image to be cropped off when it's dimensions exceeds the width of it's containing parent.</p> <p>Unfortunately, it is difficult to adjust the size of the <code><img /></code> element if you want to keep the aspect ratio <strong>and</strong> fill out all the available space.

3,850,337 | 0 | <p>There are a few issues with your approach:</p> <ul> <li>It may under-count since you don't use a transaction to atomically update the counter.</li> <li>It is inefficient: <ul> <li>Contention may become a problem if you need to update this counter frequently. Since you only have one counter, it won't scale well. Datastore entities can only be written at a rate of at most 5 times per second.</li> <li>You're writing to the datastore twice every time you insert a record. If you end up using transactions to fix the above problem, then you'll be making two round-trips to the datastore every time you insert the record (once to insert, and once to update the counter). You might be able to use an approach which avoids this extra round-trip to the datastore.</li> </ul></li> </ul> <p>Here are some alternate approaches (from least accurate [and fastest] to most accurate [and slowest]):</p> <ul> <li>If you only need a rough count of the number of entities of particular kind in the datastore, then you can use the <a href="http://code.google.com/appengine/docs/python/datastore/stats.html">Stats API</a>. The counts you retrieve are not constantly updated, however.</li> <li>If you need more granularity but are okay with a small possibility of occasionally under-counting, then you could use a memcache-enhanced counter. There are several good implementations discussed in <a href="http://stackoverflow.com/questions/2769934/high-concurrency-counters-without-sharding">this question</a>. In particular, see the code in the comments in <a href="http://appengine-cookbook.appspot.com/recipe/high-concurrency-counters-without-sharding/">this recipe</a>.</li> <li>If you really want to avoid undercounting, then you should consider a <a href="http://code.google.com/appengine/articles/sharding_counters.html">sharded datastore counter</a>. This will eliminate the contention issue from above.</li> </ul> |

4,110,800 | 0 | Silverlight ListBox control doesn't rebind correctly <p>I'm using a ListBox control with an ItemTemplate like so:</p> <pre><code><ListBox Name="lbItemsList" ItemsSource="{Binding}" > <ListBox.ItemTemplate> <DataTemplate> <StackPanel Orientation="Horizontal"> <TextBlock Text="{Binding ID}" Padding="5,0,0,0" /> <TextBlock Text=" - " Padding="5,0,0,0" /> <TextBlock Text="{Binding Description}" Padding="5,0,0,0" /> </StackPanel> </DataTemplate> </ListBox.ItemTemplate> </ListBox> </code></pre> <p>Then, in the code I dynamically bind a collection to the ListBox like so:</p> <pre><code>lbItemssList.ItemsSource = _itemsList.Values; </code></pre> <p>But at times I need to rebind a different or modified list of items to the ListBox.

28,490,593 | 0 | Error on using Vim-latex ("can't find file ~") <p>I'm not sure if this question is appropriate here but I have nowhere else to ask. I recently started to typeset some 'mathsy' stuff using Latex and it became a hobby for me. I've been using TeXnicCenter for this, but feeling that I've got familiar with Latex language, I decieded to improve 'efficiency' of typesetting by changing the editor.</p> <p>So I decided to use <strong>Vim</strong> (latest version, 7.4) with Suite-Latex. I've just installed Vim and Suite-Latex, following exactly what was instructed <a href="http://vim-latex.sourceforge.net/index.php?subject=download&title=Download" rel="nofollow">here</a>. I made every necessary changes mentioned <a href="http://vim-latex.sourceforge.net/documentation/latex-suite/recommended-settings.html" rel="nofollow">here</a>, and it seemed to me that installation was successful (I got what was expected on Step 4)</p> <p>Then I started to work through <a href="http://vim-latex.sourceforge.net/documentation/latex-suite-quickstart/lsq-using-tutorial.html" rel="nofollow">this tutorial</a> and everything went fine until <a href="http://vim-latex.sourceforge.net/documentation/latex-suite-quickstart/lsq-inserting-reference.html" rel="nofollow">this section</a>.</p> <p>When I press F9 for autoreference, I see that Vim is working on something for split seconds and red error message refering to "can't find [some file name]" in my user/appdata/local/temp directory. The "file name" changes every time I do this (so its kind of temporary file as its directory suggests?). And then it produces a new window with title <strong>__ OUTLINE __</strong> where 2 empty lines are showing up.</p> <p>If I press n (in the new window described above) error message saying <strong>"E486: Pattern not found: rf"</strong> pops up and pressing j results in going down one row. If I press enter key, message <strong>":call Tex_FinishOutlineCompletion()"</strong> pops up.</p> <p>More frustratingly, if I try to compile a file by entering command \ll, a new window pops up where there are two lines saying:</p> <p>1.ll I can't find file `newfile.tex'. newfile.tex</p> <p>2.ll Emergency stop</p> <p>and below these is a message saying </p> <p><strong>[Quickfix list]: latex -interaction=nonstopmode -file-line-error-style newfile.tex</strong></p> <p>So I thought it maybe is something to do with VIM not being able to find files in my computer (so something wrong with grep?), and I tried to resolve it by downloading a software called "cygwin" on which developers said their tests were successful, but it changed nothing.</p> <p>But I think the two problems are related.</p> <p>As it is, I am completely newbie in this type of editing environment (or any kind of programming) but I really would like to learn some Vim seeing how efficient it is in typesetting etc. Sorry for not being a pro at typing codes here. Thanks for reading!</p> |

6,206,177 | 0 | <p>The plus: it's a super easy way to distribute the work that needs to be done.</p> <p>The minus: due to the way that Hadoop recovers from failures, you need to be very careful about managing what is and isn't run (which you can definitely do, it's just something to watch out for). If a reduce fails, for example, then all of the map jobs that feed that partition must also be rerun. Obviously this would most likely be a no-reducer job, but this is still true of mappers...what happens if half of the calls run, then the job fails, so it is rescheduled?</p> <p>You could use some sort of high-throughput system to manage the calls that are actually made or somesuch. But it definitely can be appropriately used for this.</p> |
