"Scaling a UIView from a point other than the center, looking for alternatives to anchorPoint",

I'd like to scale it so that it stretches towards the left, as if it were zooming towards the left. I can accomplish this by setting the anchorPoint to the right center. However, this causes problems with setting the frame, etc. Is there a better way to apply a scale transform like I want.

"Initialize a largest product counter as an \"infinitely\" small number",
"I'm implementing a simple algorithm in java that takes in an array of integers, and finds and returns the largest product of adjacent integers in the array. To do this I first initialized a variable called largestProduct which I use to keep track of the current biggest (best) product found. I want to make sure that the initial value of this product is immediately replaced by the first product I find, so I set the initial value to a very small number (-1000000). This solution works since each number in the array is restricted to the domain -1,000 - 1,000 so the smallest the product could be is 1,000,00. However, this solution seems nonideal, and would need to be changed if the domain changed. \n\nTo try and guarantee that my initial value be replaced I tried setting largestProduct's initial value to null, and also tried not giving it any intial value, but these both gave me a compilation error. So my question is, is there a way to set a variable's (of type int) initial value to an \"infinitely\" small value, or what would be the best way to handle this situation otherwise?\n\nHere is my code\n\nint adjacentElementsProduct(int[] inputArray) {\nint largestProduct = -1000000; \nint n = 1;\nwhile(n < inputArray.length){\n int tempProduct = inputArray[n-1]*inputArray[n];\n if(tempProduct > largestProduct){\n largestProduct = tempProduct;\n }\n n++;\n}\nreturn largestProduct;\n}"

"Debugging puppet: how do I show the available modules in a manifest?",
"My context:\n\n\nI'm including a module which in turn includes more modules\nwhen I run a \"puppet apply\" the first included module runs fine...\nuntil it gets to the \"include\" statement for the other module\nthe mechanism I'm using to include modules is nonstandard and is part of the infrastructure I'm working in. Usually I could just check a directory and see if the module is there... but since there is \"magic\" involved in including modules, I have to debug during the apply.\n\n\n\n err: Could not retrieve catalog from remote server: Error 400 on SERVER: Could not find class missingmoduleclassname\n\n\nMy question:\n\n\nI'd like to print out the available modules to stdout during the apply. Is there a way to do that? \nI'm already using code like: notify{\"The list of modules available is: ${yourvar}\": }\n\n\nIs there a variable I can print out? What is it called?"

"Polymorphism Conundrum",
"Now, I appreciate this is actually an opinion based question, so I expect it to be closed, but hopefully not before a few answers appear. The subject matter I'm dealing with is new to me, but also it is massive. I could spend a year here and still only be chipping the tip of the iceberg, hence why I've got myself a little stuck.\n\nSo, I have the situation where I have three real world objects, let's call them HelloWorld, Foo and Bar. Bar has all the same properties as Foo EXCEPT for one. This particular property is not valid for a Bar. Instead, Bar has an additional property which is unique to that type. So, in my head it makes sense for Bar to inherit Foo. Now a HelloWorld can have a Foo OR a Bar depending on the circumstances and operations will proceed differently depending on which one it holds. \n\nWhat I want to know is - does the example below hold water, or does it have a code smell like week old haddock left in the sun?! If it does smell, what would be the 'right' way to go? This is all new code - I'm not refactoring, so I have the ability to do it right the first time.\n\npublic class Foo\n{\n // This property is valid for Foo AND Bar\n public int Property1 { get; set;}\n\n // This property is valid for Foo ONLY.\n public virtual string Property2 { get; set;}\n}\n\npublic class Bar\n{\n // This cannot exist in Bar - so always return null, don't allow it to be set.\n public new string Property2 => null;\n\n // Unique to Bar.\n public List<int> Property3 { get; set;}\n}\n\npublic class HelloWorld\n{\n public Foo FooProperty { get; private set;}\n\n private HelloWorld()\n {\n }\n\n // Create a new object with the property as a Foo.\n public static HelloWorldWithFoo()\n {\n return new HelloWorld()\n {\n FooProperty = new Foo()\n };\n }\n\n // Create a new object with the property as a Bar.\n public static HelloWorldWithBar()\n {\n return new HelloWorld()\n {\n FooProperty = new Bar()\n };\n }\n}\n\n\nEDIT\n\nOk - so my 'generic' example maybe lacked the context needed - apologies. Having taken onboard the comments etc, I've applied it like so - and used the real world types for clarity.\n\npublic class Slot\n{\n public CardBase CardDetails { get; set; }\n\n private Slot()\n {\n }\n\n public static Slot CreateSlotWithCard()\n {\n return new Slot()\n {\n CardDetails = new Card()\n };\n }\n\n\n public static Slot CreateSlotWithCarrierCard()\n {\n return new Slot()\n {\n CardDetails = new CarrierCard()\n };\n }\n}\n\npublic class CardBase\n{\n public string Name { get; set; }\n public DateTime InstallationDate { get; set; }\n public HardwareType Type { get; set; }\n}\n\npublic class Card : CardBase\n{\n public List<int> Ports { get; set; }\n}\n\npublic class CarrierCard : CardBase\n{\n public List<Card> SubCards { get; set; }\n}\n\n\nDoes this look a little more along the right lines??"

"select from table where two parameters satisfy in mysql",
"I am totally clueless how to get around to get the following kinda result from the same table in MySQL.\n\nRequired Result:\n\n\n\nThe raw data as shown in below image.\n\n\n\nMc_id and op_id can be different. For example, if mc_id is 4 and op_id is 10 then it has to loop through each vouid and extract done_on_date, again it has to loop through for the same mc_id 4 and op_id 10 and extract done_on_date where done_on_date is after first extracted done_on_date. Here second extracted done_on_date, we refer to, as next_done_on_date, just to distinguish it differently. Accordingly continue till end of the table. I hope I am clear enough now.\n\nThe idea is basically to see when was particular operation_id carried out for the said machine having mc_id. First time operation done is refered to as done_on_date and when the same operation carried out for the same machine next time, we refer to as next_done_on_date but actually inside the database table it is done_on_date.\nThough let me know if anything yet to be clarified"

It's as if Babel is using different settings to process the async-mutex package than it uses to process my index.js.\nI found another question with an answer that suggests adding target: ['web', 'es5'], but that doesn't help and it also seems unnecessary, since Webpack is supposed to honor browserslist.\nWith Webpack 4 I did not have this issue, but I'm not sure if the problem is with my setup, with Webpack, with Babel or even with async-mutex.\nNote aside: I'm aware that this minimal setup is lacking a Promise polyfill, but I omit it here because it seems irrelevant to the issue."

"How do I create an ECDSA certificate with the OpenSSL command-line",
"I'm building a server app in C++ that needs to accept a certificate containing an ECDSA public key. It must validate the certificate and, upon verification, use the public key contained in the certificate to authenticate a message sent along with the certificate. \n\nI have all this working using ECDSA keypairs generated on the fly - i.e. my code is working nicely - but now I need to do the certificate piece. \n\nAnd I figured I could use OpenSSL's command-line to create the certificate which is installed on the client (along with the ECDSA private key in a separate file).\n\nCan anyone help?"

"Filter and Map versus Reduce",
"I am having trouble understanding the performance difference between doing a combination of a filter then a map on the filtered list compared to just iterating over the list once and doing a reduce.\nIn terms of the joint filter and map I see that we would have to iterate twice over a list. The first time to filter and then we iterate over the shorter filtered list. However, overall this should still be an O(n) operation, correct?\nFor the reduce operation the only difference I see in terms of runtime is that we only have to iterate over the list once and we can do the filtering and mapping all in one go.\nBut in either case shouldn't the run time still be O(n)? How are they different in terms of runtime performance?"
