[ "Safety of using token claims in Firestore client side and grouping notifications", "I have already and app which is developed by Ionic-Angular and have a REST API which is developed by Nodejs and Mongodb. After hearing about Firebase, I decided to redevelop it by that.\n\nIn my old app, I used a single DB for all customers and seperate them and their data that they can read and write by a groupId. \n\nI save their groupId in their jwt token and send it in the request header to the backend. In the backend I will get this groupId and filter requested data by that groupId, or when they post or put data, I also check and use this groupId. In this case they are able just to see or change the data of their group. Also I send message by Socket.io to that specific group to update their data and have real time data.\n\nMy questions about the new app (Firebase) are:\n\n\nIs it safe to set and get data by the group_id which I get from user token in Firestore client side? (I don't like to use API because I don't have real time data anymore). Is user able to change the group_id and get the data of other groups?\nFirebase notifies all users about the changes and refresh their data to get the updates and they have real time data. In my case, I need to update the data of the specific group which its data is changed. Is it possible to do that or all users in all groups always refresh their data when changes occur in DB? \n\n\nEDITED:\n\nHere is the code sample. \nI need to know if a malicious user can change the value I send in \"where\".\nIf yes, how can I secure if with firebase rules for reading data? \n\n loadAllUnits(): Observable<Unit[]> { \n return this.db.collection(\n 'units',\n ref => ref.orderBy(\"name\")\n .where('groupId', '==', this.authService.currentUser.value.groupId)\n ) \n .snapshotChanges()\n .pipe(\n map(snaps => convertSnaps<Unit>(snaps)));\n }" ]

[ "Unity3D: Resource.Load defined AudioClip ends up Null going into the AudioSource", "What I'm trying to do is contain an audio file in a folder (under Resources) where I can drop any qualifying audio file in the specified folder and have the numerous triggers in my program read from that single point (which is why my AudioClip below is public static so I can reference it). Currently, the same audio file works throughout the program, but to change the file requires manual redefining in the Inspector which my eventual client won't have access to, and besides is tedious due to the numerous reference points that exist.\n\nHere's what I have so far:\n\npublic static AudioClip BGM;\npublic AudioSource BGMSource;\nprivate string formatted1;\n\nvoid Start()\n{\n foreach(string file in System.IO.Directory.GetFiles(Application.dataPath+\"/Resources/Audio/BGM\"))\n {\n if(file.EndsWith(System.IO.Patch.GetExtension(\".mp3\")))\n {\n formatted1 = file.Replace(\".mp3\",string.Empty);\n BGM = Resources.Load<AudioClip>(formatted1); \n //BGM = (AudioClip)Resources.Load(formatted1,typeof(AudioClip)); <--same result with this\n Debug.Log(\"found: \"+formatted1);\n }\n\n }\n if(BGM == null)\n {\n Debug.Log(\"Yeah, its null\");\n }\n\n BGMSource.PlayOneShot(BGM, .9f);\n\n if(BGMSource.isPlaying != true)\n {\n Debug.Log(\"I'm not playing\");\n }\n}\n\n\nSo as is, this just doesn't play, no error messages. Turns out BGM is null. The Debug says as so, but if I were to add a Debug call for BGMSource.clip.name, it will fully error out with a NullReferenceException on that Debug.\n\nThe Debug for the formatted1 string (File path and name), it does present the correct file called Test.mp3 (\"C:/...Resources/Audio/BGM\\Test\") formatted without the \".mp3\" as was recommended from another site. I did try with the .mp3 extension on, didn't seem to matter, still didn't play. I also tried with a .wav file and .ogg file, same result (note: all files were fine if I attached as a public AudioClip manually as also the AudioSource as written above would play in that case, but as I lead with, we don't want that for this case). Yes, all test audio files were in the directory /Resources/Audio/BGM. \n\nAnother site said something about adding to the top of the file [RequireComponent(typeof(AudioClip))] or [RequireComponent(typeof(AudioSource))]but that did nothing.\n\nLastly, this program will eventually be given to a group that won't have source access so they MUST be able to swap the audio file by dropping any .mp3 in Resources/Audio/BGM for auto play.\n\nAny help is welcome, thanks!" ]

Naturally I want NOT to repeat the code (even if it's easy to do that, because its just a copy paste routine). A friend suggested macro... but that would look dirty. Is this simple, because if it is Im quite stupid to know right now. Would appreciate any suggestions/help.\n\nEdit: Im sorry for those wanting a code example. The question was really meant to be abstract as I encounter different \"similar\" situation in which I ask myself how I am able to make the code shorter/cleaner. In most cases codes are long otherwise I wouldn't bother asking this in the first place. As KilianDS pointed out, it's also good to make sure that the function itself isn't very long. But sometimes this is just unavoidable. Many cases where I encounter this, the loop is even nested (i.e. several loops within each other) and the beginning of F we have the start of a loop and the end of F we end that loop.\n\nJose" ]

It works really well and has drastically simplified the release procedure.\n\nI was made aware of an issue on one of our live sites this weekend that would have been prevented had the site been precompiled (long story).\n\nSo I've been playing around with injecting the AspNetCompiler MSBuild Task (using the PhysicalPath attribute to direct towards the intermediate publish folder) into the deployment script and I have a question regarding the 'VirtualPath' option.\n\nDespite the fact that the website is not in IIS at this pre-deploy stage, you are still required to provide a value for the 'VirtualPath' attribute. I have seen here that the associated -v switch on aspnet_compiler.exe uses this value in resolving '~' rooted virtual paths used throughout the site during the compilation.\n\nSo, I take this to mean that whatever you pass here must be the virtual root of the application when deployed otherwise it won't work. \n\nHowever, I've tried this out, passing something like '/fake/fake' in this option and then changing one of my master pages to reference a css via an app-rooted url instead of relative, and it still worked even when deployed to a virtual path of '/site' and not '/fake/fake'.\n\nSo what's the definitive answer on this? Do I need to worry about this VirtualPath value being exactly equal to the eventual deployed location of a site in IIS?

I get segfaults and \"zend_mm_heap corrupted\" errors, but the backtraces from those points are not useful. The backtraces always lead back to various core PHP functions such as variable assignment or concatenation.\n\nTo the best of my knowledge, PHP's memory is getting corrupted at some point before the segfaults/heap corruption errors occur.\n\nI've followed the instructions at bugs.php.net/bugs-getting-valgrind-log.php and have generated a quite large valgrind log. It's filled with many errors like \"Conditional jump or move depends on uninitialised value\". Because there's so much information in that valgrind log, I'm not sure what is a true defect and what is normal behavior.\n\nHere's a portion of the valgrind output: http://pastie.org/private/exngtften3jeppqyjn4hw" ]

As you can see it is a listing of each file that exists. The LimitsA file will contain the limits for every Data file of type A.\n\nID File_Name Type Sub-Type\n1 DataA_10 A 10\n2 DataA_20 A 20\n3 DataA_30 A 30\n4 LimitsA A NONE\n5 DataB_10 B 10\n6 DataB_20 B 20\n7 LimitsB B NONE\n\n\nThe \"Data\" table looks like this. The File_ID is the foreign key from the \"Files\" table. Specifically, this would be data for DataA_10 above:\n\nID File_ID Dat1 Dat2 Dat3... Dat20\n1 1 50 52 53 \n2 1 12 43 52 \n3 1 32 42 62 \n\n\nThe \"Limits\" table looks like this. The File_ID is the foreign key from the \"Files\" table.

Each row of DataA_10 would have the limits of \"40\" and \"60\" from the LimitsA table. Unfortunately there is no way to directly link the limits table to the data table. The only way to do this would be to look back to the files table and see that LimitsA and DataA_10 are of type A. Once I link those two together I then need to specifically only grab the Limits for Sub-Type 10.\n\nIn the end I would like to have a result that looks like this.\n\nResult:\n\nID File_ID Dat1 Dat2 Dat3...
