"Custom allocation and Boehm GC",
"In my on-again-off-again compiler project, I've implemented closures as allocated memory with an executable prefix. So a closure is allocated like this:\n\nc = make_closure(code_ptr, env_size, env_data);\n\n\nc is a pointer to a block of allocated memory, which looks like this:\n\nmovl $closure_call, %eax\ncall *%eax\n.align 4\n; size of environment\n; environment data\n; pointer to closure code\n\n\nclosure_call is a helper function that looks at the address most recently placed on the stack and uses it to find the closure data and code pointer. Boehm GC is used for general memory management, and when the closure is no longer referenced it can be deallocated by the GC.\n\nAnyway this allocated memory needs to be marked as executable; in fact the entire pages it spans get marked. As closures are created and deallocated, more and more heap memory in the process will be executable.\n\nFor defensive programming reasons I'd prefer to minimise the amount of executable heap. My plan is to try to keep all closures together on the same page(s), and to allocate and deallocate executable pages as needed; i.e. to implement a custom allocator for closures. (This is easier if all closures are the same size; so the first step is moving the environment data into a separate non-executable allocation that can be managed normally. It also makes defensive programming sense.)\n\nBut the remaining issue is GC. Boehm already does this! What I want is to somehow tell Boehm about my custom allocations, and get Boehm to tell me when they're able to be GC'd, but to leave it up to me to deallocate them.\n\nSo my question is, are there hooks in Boehm that provide for custom allocations like this?"

"React: Pass context to dynamically loaded component",
"I have a component that's being loaded dynamically, something like this:\n\nLoadScript(\"path/to/component.bundle.js\", () => {\n let comp = getComp()\n ReactDOM.render(<Provider store={store}>\n {comp}\n </Provider>, container)\n})\n\n\nand in the component.js:\n\nexport function getComp() {\n return <MyComponent />\n}\n\n\nHowever, the MyComponent does not have access to the store (which works if not loaded dynamically). If I change it to:\n\nexport function getComp() {\n return <Provider store={store}><MyComponent /></Provider>\n}\n\n\nthen it works, but the store doesn't really seem to be associated (like if there were 2 stores active). The store is created with createStore from 'react-redux'.\n\nCan anyone tell why MyComponent is not receiving the store/Provider context correctly? Thanks!\n\nUPDATE:\n\nI believe the problem is that I'm using code-splitting and loading both bundles together doesn't work.\n\nIn my webpack.config.js, I have:\n\nentry: {\n admin: './js/index.admin.js',\n kiosk: './js/index.kiosk.js'\n},\noutput: {\n filename: '[name].bundle.js',\n path: path.resolve(__dirname, 'dist'),\n libraryTarget: 'window',\n},\noptimization: {\n splitChunks: {\n chunks: 'all',\n maxInitialRequests: 2\n }\n}\n\n\nThen, from 'admin' I try to load the 'kiosk' bundle. That's creating 2 stores. Which makes sense since both bundle index files have the following at the top:\n\nimport store from './store'\n\n\nand store.js is defined as:\n\n...\nexport default createStore(reducer, middleware)\n\n\nThere's no problem with the reducers since they are all included in both bundles. \n Note this is not a SPA, but a legacy application that has some components in React."

"Most, if not all, VHDL textbooks casually list the arithmetic operators and amongst them even more so casually the Shift Left Arithmetic (SLA) as shift left that fills with rightmost element. Although even wikipedia disagrees with this definition, I have never seen anyone to even blink an eye to this definition, it's just taken in with a face value, \"yup, makes sense\".\n\nHowever, the apparent complete uselessness of filling with the rightmost value in binary arithmetics made me to wonder - has anyone found a really good use for SLA in real life? \n\n(I'm not against the existence of SLA, nor want to eradicate it from VHDL.

"Is it possible to overload Func and Func having the same name?",
"First of all, I know I can just define two overloaded helper methods to do what I need (or even just define two Func<>s with different names), but these are only used by one public method, so I'm exploring ways to define two local Func<>s that also overload by using the same name. Take, for example:\n\nstring DisplayValue(int value)\n{ return DisplayValue(value, val => val.ToString()); }\n\nstring DisplayValue(int value, Func<int, string> formatter)\n{ return (value < 0) ? \"N/A\" : formatter(value); }\n\n\nI need to call one or the other version many times in my public method to custom format special values, so I thought I could \"translate\" the above into something like this:\n\nFunc<int, Func<int, string>, string> displayValue =\n (value, formatter) => (value < 0) ? \"N/A\" : formatter(value);\n\nFunc<int, string> displayValue =\n value => displayValue(value, val => val.ToString());\n\n\nEven as I was typing it I knew I couldn't declare two delegate identifiers having the same name, even if they are different types. This is more academic than me being dead set on achieving overloads using Func<>s, but I guess they just can't do everything, right?\n\nAnd I guess you can't do something like this, either:\n\nFunc<string, params object[], string> formatArgs =\n (format, args) => string.Format(format, args);"

"Is there any reason to continue using IntentService for handling GCM messages?",
"As you know, recently Google changed their GCM documentation, and they claim that an IntentService is no longer required for handling arriving GCM messages. All the handling can be done in the BroadcastReceiver.\n\nWhen trying to figure out if there is any good reason to continue using the IntentService, I came across this quote:\n\n\n A Service (typically an IntentService) to which the WakefulBroadcastReceiver passes off the work of handling the GCM message, while ensuring that the device does not go back to sleep in the process. Including an IntentService is optional—you could choose to process your messages in a regular BroadcastReceiver instead, but realistically, most apps will use a IntentService.\n\n\nWhy would most apps use an IntentService? Are there any scenarios in which handling the GCM message directly in the BroadcastReceiver won't work?"

"How to get jackson to ignore non-DTO objects",
"We recently upgraded to GlassFish Jersey 2.7 from the Sun Jersey implementation. When we did this Jackson started trying to deserilize our Domain objects. Which in our case isn't what we want. We have Domain setup so that domain objects are never directly sent out via the web services. Everything is transformed in to a DTO and then sent out. So basically we just call\n\nreturn Response.ok(new SomeFooBarDTOObject(someFooBarDomainObject)).build()\n\nand this use to work with the previous version of Jersey/Jackson. With the more up to date code we're getting errors like the following:\n\nConflicting setter definitions for property \"preferredItem\": com.foo.domain.FooBar#setPreferredItem(1 params) vs com.foo.domain.FooBar#setPreferredItem(1 params)\n\nEven though we never try to send out the actual domain object. How do we tell Jackson to only look at objects that are actually received or sent via a web service.\n\nHere is the web service that is causing the issue I've simplified it down to just this. If I take out the RestaurantItemDTO restaurantItemDTO from the method parameters it works, but if I keep it in there it doesn't.\n\nRestaurantItemDTO only has base types in it's fields. The only way it references a domain object is through a constructor parameter, and there is also a public no parameter constructor as well. So it's not the only constructor.\n\n@Controller\n@Path(\"/restaurant/restaurantItem\")\npublic class RestaurantItemWebService {\n @PUT\n @Path(\"/ordersheets/{ordersheetId}/{locationId}/restaurantItems/{restaurantItemId}\")\n @Produces(value = MediaType.APPLICATION_JSON)\n @Consumes(value = MediaType.APPLICATION_JSON)\n @Transactional\n @PreAuthorize(\"hasRole('\" + PermissionNames.SOME_PERMISSION+ \"')\")\n public Response saveExistingRestaurantItem(@PathParam(\"ordersheetId\") Long orderSheetID, @PathParam(\"restaurantItemId\") Long restaurantItemID, RestaurantItemDTO restaurantItemDTO) {\n return Response.ok(restaurantItemDTO).build();\n }"

"Update Widget on System Broadcast Intent",
"I'm working on an Android widget that will show the current network state (i.e 1xRTT, EvDo Rev. A, WiMax, etc.). It may seem like a pointless idea, but for whatever the reason, the Evo doesn't differentiate between 1x & EvDo, it just says 3G for both, which is annoying if you're in a fringe 3G area.\n\nAnyways, to the point: I have the widget complete and it updates with the current network just fine, but how can I make it update whenever the connection changes? I know I can use a BroadcastReceiver to catch the ConnectivityManager.CONNECTIVITY_ACTION intent the system sends on a connection change. How can I update the widget from there?\n\nOr can I use the AppWidgetProvider to catch the intent and then update?\n\nI know how to catch the intent, I just don't know how to update the widget once I do."

"User Group and Role Management in .NET with Active Directory",
"I'm currently researching methods for storing user roles and permissions for .NET based projects. Some of these projects are web based, some are not. I'm currently struggling to find the best method to achieve what I'm looking for in a consistent, portable way across project types.\n\nWhere I'm at, we're looking to leverage Active Directory as our single point of contact for basic user information. Because of this, we're looking to not have to maintain a custom database for each application's users since they are already stored in Active Directory and actively maintained there. Additionally, we don't want to write our own security model/code if possible and would like to use something pre-existing, like the security application blocks provided by Microsoft.\n\nSome projects require only basic privileges, such as read, write, or no access. Other projects require more complex permissions. Users of those applications might be granted access to some areas, but not others, and their permissions can change across each area. An administration section of the app would control and define this access, not the AD tools. \n\nCurrently, we're using integrated Windows Authentication to perform authentication on our intranet. This works well for finding out basic user information, and I've seen that ASP.NET can be extended to provide an Active Directory roles provider, so I can find out any security groups a user belongs to. But, what seems like the downfall of this method to me is that everything is stored in Active Directory, which could lead to a mess to maintain if things grow too big. \n\nAlong this same line, I've also heard of Active Directory Lightweight Directory Services, which seems like it could extend our schema and add only application specific attributes and groups. Problem is, I can't find anything on how this would be done or how this works. There are MSDN articles that describe how to talk to this instance and how to create a new instance, but nothing ever seems to answer my question.\n\nMy question is: Based on your experience, am I going down the right track? Is what I'm looking to do possible using just Active Directory, or do other tools have to be used?\n\n\n\nOther methods I've looked into:\n\n\nUsing multiple web.config files [stackoverflow]\nCreating a custom security model and database to manage users across applications"

"In Ruby on Rails, how to intercept the Devise gem's email sending functionality and change it to call an API instead?",
"I have a working Rails installation with the Devise gem. Instead of sending emails for example for password recovery, I would like to make an API call. Is there a method or a file in Devise that I need to change to change the default email sending behaviour, and be able to send the same email content through an API instead?"

"Using exclusive + durable queues, for RabbitMQ",
"If I have made a queue which is exclusive and durable (not auto-delete). Now, if the consumer subscribes to that queue and then it goes down. Then that queue gets deleted. \n\nI have checked the scenario, when the queue is only durable (i.e. neither exclusive nor auto-delete). Now, if the consumer subscribes to that queue and then it goes down. Then that queue gets deleted. \n\nPlease explain the 1st case, 2nd case is giving expected result. In both the scenario only 1 consumer is subscribed to one queue, and there is only one queue bound to one direct_exchange."
