"Accessing constants using Key-Value Coding in Objective-C",
"I'm making a program that has a lot of constants. I decided to put them all into a separate class and I'm importing it by the classes that need it. The files look similar to this\n\n// Constants.h\nextern const int baseCostForBuilding;\nextern const int maxCostForBuilding;\n// etc\n\n// Constants.m\nconst int baseCostForBuilding = 400;\nconst int maxCostForBuilding = 1000;\n// etc\n\n\nWhat I'm trying to do is access them using key-value coding. What I've tried so far hasn't worked.\n\nid object = [self valueForKey:@\"baseCostForBuilding\"];\n\n\nBut I can do the following and it works fine.\n\nid object = baseCostForBuilding;\n\n\nThis may seem pointless but I have a lot of variables that have to end in \"CostForBuilding\" and the function I need this in only gets the first part of the string. Example, \"base\", \"max\", \"intermediate\", etc. It will then combine it with \"CostForBuilding\" or something else to get the variable name.\n\nIf this is possible, it would be way nicer to only have one or two lines of code instead of multiple if-statements to access the correct variable. Does anyone know a way to do this? Thanks in advance."

"How do I access different python module versions?",
"so I am working on a shared computer. It is a workhorse for computations across the department. The problem we have run into is controlling versions of imported modules. Take for example Biopython. Some people have requirements of an older version of biopython - 1.58. And yet others have requirements for the latest biopython - 1.61. How would I have both versions of the module installed side by side, and how does one specifically access a particular version. I ask because sometimes these apis change and break old scripts for other people (or they expect certain functionality that is no longer there).\n\nI understand that one could locally (i.e. per user) install the module and specifically direct python to that module. Is there another way to handle this? Or would everyone have to create an export PYTHONPATH before using?"

"DDD naming: Domain Object",
"Consider certain kinds of objects involved Domain-Driven Design (DDD): Entities, Value Objects, Domain Events, and Domain Services.\n\nWhich of these are considered to be Domain Objects? And are there other names for abstractions that encapsulate a subset of those?\n\nI can identify various abstractions that are useful to have when talking about DDD or domain models:\n\n\nEntities and Value Objects. I often find myself mentioning \"Entities or Value Objects\". Most notably, these are the ones that model the domain's state. In contrast, Domain Services are stateless, and I would argue that Domain Events merely reflect information about how the domain came to be in its current state.\nEntities, Value Objects, and Domain Events. These may all contain or represent data, whereas the Domain Services only define behavior.\nAll objects recognized by the domain model. It is useful to be able to talk about parts of the domain model in general, as opposed to concepts outside of it.\n\n\nIt's interesting how even Stack Overflow's domain-object tag has a confusing definition:\n\n\n Domain Objects are objects made for dealing with the domain logic at the Model layer. These objects generally simulate real (or virtual) items from real-life: Person, Post, Document, etc.\n\n\nThe initial definition, focused on \"dealing with the domain logic\", leans towards \"all objects recognized by the domain model\". The examples then lean towards \"Entities and Value Objects\".\n\nDDD hammers on a clearly defined, unambiguous Ubiquitous Language, and with good reason. Shouldn't it lead by example? :)"

"Alternative to \"onChange\" event with Semantic UI dropdown?",

"How to minify and concat javascript and css files in Express 4",
"Is there a middleware that takes all public stuff like scripts, css, images, and fonts. And then losslessly compress them / minify, concat, replace their mention in templates with their calls. So script 1, script 2, script 3 tags let say in jade is replaced with all.concated.min.js and all images are merged into sprite sheet, losslessly compressed and then all their mentions of them in css or img tags is replaced by extra css rules that are also concated at the end of all.concat.min.css\n\ni forgot to add that this manager should also handle http caching. As it's already replacing file values at server start. So it would make logo_s3kc.png max age infinity. But if logo changes which it keeps track using its own internal way, like using checksum. then it changes the name at next start of server so all files point to logo_new.png. but when i view file i only care about logo.png. Just like you have styles.less. Then there gets compiled styles.css etc."

"Why MongoDB is Consistent not available and Cassandra is Available not consistent?",
"Mongo\n\nFrom this resource I understand why mongo is not A(Highly Available) based on below statement\n\n\n MongoDB supports a “single master” model. This means you have a master\n node and a number of slave nodes. In case the master goes down, one of\n the slaves is elected as master. This process happens automatically\n but it takes time, usually 10-40 seconds. During this time of new\n leader election, your replica set is down and cannot take writes\n\n\nIs it for the same reason Mongo is said to be Consistent(as write did not happen so returning the latest data in system ) but not Available(not available for writes) ? \n\nTill re-election happens and write operation is in pending, can slave return perform the read operation ? Also does user re-initiate the write operation again once master is selected ?\n\nBut i do not understand from another angle why Mongo is highly consistent\nAs said on Where does mongodb stand in the CAP theorem?, \n\n\n Mongo is consistent when all reads go to the primary by default.\n\n\nBut that is not true. If under Master/slave model , all reads will go to primary what is the use of slaves then ? It further says If you optionally enable reading from the secondaries then MongoDB becomes eventually consistent where it's possible to read out-of-date results. It means mongo may not be be \nconsistent with master/slaves(provided i do not configure write to all nodes before return). It does not makes sense to me to say mongo is consistent if all\nread and writes go to primary. In that case every other DB also(like cassandra) will be consistent . Is n't it ?\n\nCassandra\nFrom this resource I understand why Cassandra is A(Highly Available ) based on below statement\n\n\n Cassandra supports a “multiple master” model. The loss of a single\n node does not affect the ability of the cluster to take writes – so\n you can achieve 100% uptime for writes\n\n\nBut I do not understand why cassandra is not Consistent ? Is it because node not available for write(as coordinated node is not able to connect) is available for read which can return stale data ?"

"Our team migrated a project from GAE to AWS. One component is a web application built on top of webapp2, a framework which is easy to integrate with GAE. We kept the webapp2 framework in AWS too, with some minor changes to make it work.\n\nThe web application works fine in the cloud, but I'm trying to find a way to run it on the local development machines too. When we were using the GAE environment it was an easy task because Google provides the App Engine Launcher, a tool which simulates the cloud environment very well.\n\nIn AWS we continued making some hacks in order to start the web application using App Engine Launcher, but now we want to discard it. So, I modified the python script and it starts successfully but I don't know how to serve the static content. The static files (CSS, JS) are added to the HTML templates like link rel=\"stylesheet\" type=\"text/css\" href=\"{{statics_bucket}}/statics/css/shared.css\"/, where {{statics_bucket}} is an environment variable which points to a specific Amazon S3 bucket per environment. Of course, this doesn't work on localhost because nobody is serving static content on http://localhost:8080/statics/css/shared.css for example. The Google App Engine launcher had this feature and it did all the hard job.\n\nCould somebody point out a way to achieve my goal?"

"Building clean Nuget2 repository gives error",

"Random Line Generation For pygame",
"My goal is to make a retro lunar lander game using pygame. Right now I'm trying to create the background of mountains and platforms to land on. I would like for every time a new game is started the platforms and mountains be different. My idea is to draw a random number of horizontal lines with random lengths as the platform. I have a few problems with this:\n\n\nHow to make sure the horizontal lines don't overlap and are all accesible in regards of looking at it like you're landing.\nI think the best way to draw the mountains would be to connect the platforms with more lines that create triangles, but I have no idea where to begin to do that\n\n\nthe code I have been working for currently generates random lines, but I'm not sure how to develop the code further.\n\nfor platforms in range(1, random.randint(1, 10)):\n\n rand_x_start = random.randint(0, 400)\n rand_x_end = random.randint(0, 400)\n rand_y = random.randint(HEIGHT / 2, HEIGHT)\n\n pygame.draw.line(self.background, white, (rand_x_start, rand_y), (rand_x_end, rand_y), 2)\n\n\nI've tried looking through many questions and tutorials about random generation, but none are remotely close to what I'm looking for.\n\nA thought I had to fix the overlapping problem was if there was a way to \"read\" or \"see\" previously created lines and to limit drawing based on that some how...but I'm not sure of a way to do that."

"Dynamic Add Row to MVC View then pass to controller",
"Okay, so I've tried a ton of things, none of which I'm very familiar with, and I can't seem to figure out exactly how to get done what I need to do. It seems like a simple task, and I'm sure someone has done it!\n\nIn essence, I need to create a form that has the ability to create more fields that will bind to the model, or even just pass to the controller on submit.\n\nFirst, I have a model that is pretty straightforward. Something like:\n\npublic class Account\n{\n public string Organization { get; set; }\n public List<UserModel> Users { get; set; }\n}\npublic class UserModel\n{\n public string UserFirstName { get; set; }\n public string UserLastName { get; set; }\n public string UserEmailAddress { get; set; }\n public bool UserIsAdmin { get; set; }\n}\n\n\nMy view is a simple signup form that takes all the input necessary to create an account. It needs to have these fields, but also be able to have a link that says \"add User\" and ajax in another row with first name, last name, email, and isAdmin flag.\n\nThis is where I get stuck. I'm thinking I need something with a partial view and a custom binding to a controller as the data gets passed in, but I can't figure out how to pass in an object that contains all the users so I can iterate through it.\n\nIf anyone could even point me in the right direction, I would be very happy.\n\n-Lost"

"Uncaught Error: Template was precompiled with an older version of Handlebars",
"I'm using Bower to manage my frontend dependencies and grunt-ember-templates to precompile handlebars templates.\n\nThese are the dependencies in bower.json:\n\n\"devDependencies\": {\n \"ember\": \"~1.3.1\",\n \"jquery\": \"~2.0.3\",\n \"normalize-css\": \"~2.1.3\",\n \"jquery.cookie\": \"~1.4.0\",\n \"font-awesome\": \"~4.0.3\"\n}\n\n\n... and in package.json:\n\n\"devDependencies\": {\n \"bower\": \"~1.2.8\",\n \"grunt\": \"~0.4.2\",\n \"grunt-contrib-copy\": \"~0.5.0\",\n \"grunt-contrib-clean\": \"~0.5.0\",\n \"grunt-contrib-concat\": \"~0.3.0\",\n \"handlebars\": \"~1.3.0\",\n \"ember-template-compiler\": \"~1.4.0-beta.1\",\n \"grunt-ember-templates\": \"~0.4.18\"\n},\n\n\nHowever, when I compile and run my Ember application I get this error:\n\nAssertion failed: Ember Handlebars requires Handlebars version 1.0 or 1.1, COMPILER_REVISION expected: 4, got: 5 - Please note: Builds of master may have other COMPILER_REVISION values.\n\nUncaught Error: Template was precompiled with an older version of Handlebars than the current runtime. Please update your precompiler to a newer version (>= 2.0.0) or downgrade your runtime to an older version (<= 1.0.rc.2).\n\nAnd these are the versions:\n\n> Ember.VERSION\n> \"1.3.2\"\n> Handlebars.VERSION\n> \"v2.0.0-alpha.1\"\n\n\nAs you see handlebars is not mentioned explicitly as a dependency, but is rather resolved through Ember. But somehow it resolves to a newer (incompatible) version.\n\nHow do I fix the version of handlebars?"

"Issues with getting VoiceChannel.members and Guild.members to return a full list",
"Any time I try to use VoiceChannel.members or Guild.members it does not give me a full list of applicable members. I'm grabbing both the VoiceChannel and the Guild from the context in a text command like this:\[email protected](name='followme')\nasync def follow_me(ctx):\n if ctx.author.voice != None:\n guild = ctx.guild\n tracking = ctx.author\n channel = tracking.voice.channel\n\nLater on I've tried to use the channel like this:\nfor member in channel.members:\n if member.voice.mute != True:\n await member.edit(mute=True)\n\nHowever, it's only finding my user despite having another user in the channel.\nI found that the only way I could get an accurate representation of members in the channel is using:\nchannel.voice_states.keys()\n\nUsing voice_states, I can get an accurate list of members, but only by their IDs when I still need to manipulate the member itself.\nSo I tried this:\nfor key in channel.voice_states.keys():\n member = guild.get_member(key)\n if member.voice.mute != True:\n await member.edit(mute=True)\n\nHowever, the guild isn't pulling the right set of users and despite verifying all the IDs were correct, guild.members is also not working appropriately.\nAny input on how to get this working properly would be greatly appreciated."

"Dynamic Linq passes incorrect DateTime format to DB",
"I am using Entity Framework with Dynamic Linq library.\nHave code like this\nvar myDate = new DateTime(2021, 01, 01);\nvar res = dbContext.MyEntities.Where("CreateDate < @0", myDate);\n\nIt worked well if I run same query on local collection, but on database it returns error:\n"Conversion failed when converting date and/or time from character string."\nI checked with DB Profiler and the reason is format that is passed to database. It converts date to '2021-01-01T00:00:00.0000000' instead of expected '2021-01-01 00:00:00.000' and in result have query like\nSELECT * FROM [MyEntity] AS [a]\nWHERE [a].[CreateDate] < '2021-01-01T00:00:00.0000000'\n\nthat generates an error because SQL cannot parse this string. Tried to specify parameter as string but Dynamic Linq still converts it to this format and gives the same error in result. Are there any way to fix this behavior?"

"Valid Warehousing Strategy? Type6?",
"As a database user, I'm having problems interpreting the data in one of our tables at work. When I questioned the data team, the solution architects told me it was done this way on purpose because it is a \"Type 6\" table.\n\nFrom my limited googling, I think a Type 6 should look like this:\n\n+--------------+------------------+------------------+------------+------------+---------------------+\n| Customer_Key | Customer_Attrib1 | Customer_Attrib2 | Start_Date | End_Date | Record Updated Date |\n+--------------+------------------+------------------+------------+------------+---------------------+\n| 123 | 1 | A | 1/1/2001 | 6/8/2004 | 6/9/2004 |\n+--------------+------------------+------------------+------------+------------+---------------------+\n| 123 | 1 | A | 6/9/2004 | 4/11/2016 | 4/12/2016 |\n+--------------+------------------+------------------+------------+------------+---------------------+\n| 123 | 1 | A | 4/12/2016 | 4/3/2017 | 4/4/2017 |\n+--------------+------------------+------------------+------------+------------+---------------------+\n| 123 | 2 | B | 4/4/2017 | 5/18/2017 | 5/19/2017 |\n+--------------+------------------+------------------+------------+------------+---------------------+\n| 123 | 2 | B | 5/19/2017 | 12/31/9999 | 5/19/2017 |\n+--------------+------------------+------------------+------------+------------+---------------------+\n\n\nThe activity in question is the Customer_Attrib1, how it changed from 1 to 2 on 5/18/2017.\n\nI like this style because I can figure out what customer_attrib1 is at any point of time by using the start and end dates:\n\nselect customer_attrib1 \nfrom table \nwhere customer_key=123 \nand '2017-03-01' between start_date and end_date;\n\n\nHowever...\n\nThe table itself actually gets updated in arrears, to look like this:\n\n+--------------+------------------+------------------+------------+------------+---------------------+\n| Customer_Key | Customer_Attrib1 | Customer_Attrib2 | Start_Date | End_Date | Record Updated Date |\n+--------------+------------------+------------------+------------+------------+---------------------+\n| 123 | 2 | A | 1/1/2001 | 6/8/2004 | 5/19/2017 |\n+--------------+------------------+------------------+------------+------------+---------------------+\n| 123 | 2 | A | 6/9/2004 | 4/11/2016 | 5/19/2017 |\n+--------------+------------------+------------------+------------+------------+---------------------+\n| 123 | 2 | A | 4/12/2016 | 4/3/2017 | 5/19/2017 |\n+--------------+------------------+------------------+------------+------------+---------------------+\n| 123 | 2 | B | 4/4/2017 | 5/18/2017 | 5/19/2017 |\n+--------------+------------------+------------------+------------+------------+---------------------+\n| 123 | 2 | B | 5/19/2017 | 12/31/9999 | 5/19/2017 |\n+--------------+------------------+------------------+------------+------------+---------------------+\n\n\nCan you see how much trouble I have, if I want to go find what the customer_attrib1 was during March of 2016? \n\nNOTE: There is a previous_customer_attrib1 column, but it also gets mass updated to the value of 1. I wanted to keep the table small enough to get the point across, which is why I didn't add it above.\n\nThe big question: Is this a valid warehousing strategy? Is this really what Type 6 is? Or is my solution architect wrong. \n\nFollow up question: Would the answer be different if customer_attrib1 was a foreign key to another table?"
