This is out of pure curiosity and all style has been placed in it's own file.

[ "progressmeter is updated too rarely", "I have progressmeter in my XUL source code and button that I created for testing, that increments value of progressmeter by constant value.\nProblem exists because if value of increment is smaller than 4, progressmeter won't be updated.\nFor example if that const value is 1, value must be increment four times, to see change on the screen. Also internal value of progressmeter's object is not updated, ie logging variable progressmeter.value give non updated result.\nAnalogously if I increment value by 2, I must do it two times to see result. \nIt does not depend on max value, the same behaviours is if max is 100 or 2000.\n\nFor example:\n\n<progressmeter value=\"0\" max=\"100\" id=\"progressmeter1\" />\n\nvar pm_value = 0;\nfunction incrementProgressmeter(){\n var value_for_increment = 1;\n pm_value += value_for_increment;\n var progressmeter = document.getElementById(\"progressmeter1\"); \n progressmeter.value = pm_value;\n}\n\n\nIf value of value_for_increment is 1, I must invoke incrementProgressmeter function four times to see on the screen that progressmeter is progressing and also progressmeter.value is updated after that time.\nIf value of value_for_increment is 2, I must invoke incrementProgressmeter function two times. This behaviour doesn't depend on max attribute of progressmeter.\n\nI wonder if it is designed behaviour, but I don't understand reason why it may be designed in such way. If it is, I would like to know why.

[ "Using Dependency Injection for hardware abstraction", "I've been playing around with Dependency Injection in connection with hardware abstraction. So, basically I have some hardware devices which i want to control from within a C# application. These devices have usually a root device which is used to access leaf devices. The structure is quite simple: LeafDevice1 & 2 are connected through Interface1 to RootDevice1, LeafDevice3 is connected to RootDevice2 and so forth.\n\nNow i thought i can solve this issue with dependency injection since \"leaf\" devices usually don't care how they're connected as long as they're connected to a specified interface. But I'm wondering if Dependency Injection using an IOC container is actually the best way to do it. The main reason for my doubts is:\nI use named dependencies ALL THE TIME. If I connect device B and C to root device A I want to make sure that they're referring to the exact same device. Also, I use a lot of singleton scopes since a named dependency xyz should only exist once.\n\nSo in my situation configuring the container means gluing together a lot of named dependencies.\n\nAs I understand it, using IOC containers makes most sense when you want to specify which implementation will be injected. But as far as I can see, I'm using the container to manage which specific object is used where. The actual implementation of said object can, of course, be different, but it's still more of a \"what is used where?\" not a \"which implementation is used\" question.\n\nWouldn't it be better to build something like a device tree which i can use to access my devices?\n\nBind<RootDevice>().ToConstructor<RootDevice>(e => new RootDevice(serialNumber))\n .InSingletonScope().Named(\"ConcreteRootDevice\");\n\nBind<IBusMaster>().ToMethod<IBusMaster>(e => e.Kernel.Get<RootDevice>(\"ConcreteRootDevice\")\n .GetBusMaster(0)).Named(\"ConcreteBus1\");\n\nBind<IBusMaster>().ToMethod<IBusMaster>(e => e.Kernel.Get<RootDevice>(\"ConcreteRootDevice\")\n .GetBusMaster(1)).Named(\"ConcreteBus2\");\n\nBind<IBusMaster>().ToMethod<IBusMaster>(e => e.Kernel.Get<RootDevice>(\"ConcreteRootDevice\")\n .GetBusMaster(2)).Named(\"ConcreteBus3\");\nBind<IBusMaster>().ToMethod<IBusMaster>(e => e.Kernel.Get<RootDevice>(\"ConcreteRootDevice\")\n .GetBusMaster(3)).Named(\"ConcreteBus4\");\n\nBind<LeafDevice>().ToConstructor<LeafDevice>(o =>\n new LeafDevice(o.Context.Kernel.Get<IBusInterface>(\"ConcreteBus1\")))\n .Named(\"ConcreteLeafDevice1\");\n\nBind<LeafDevice>().ToConstructor<LeafDevice>(o =>\n new LeafDevice(o.Context.Kernel.Get<IBusInterface>(\"ConcreteBus1\")))\n .Named(\"ConcreteLeafDevice2\");\n\nBind<LeafDevice>().ToConstructor<LeafDevice>(o =>\n new LeafDevice(o.Context.Kernel.Get<IBusInterface>(\"ConcreteBus2\")))\n .Named(\"ConcreteLeafDevice3\");\n\n\nIn this example LeafDevices would depend on an abstract IBusInterface to communicate with the actual hardware devices. Root Device offers several BusMasters which can be used to communicate with said leaf devices.\n\nThanks in advance" ]

[ "Thread data encapsulation best practices", "I have a question how to encapsulate data gracefully in such case.\nLet's think we want to make some class that can asynchronous download images from internet. Let us have unblocking method:\n\nvoid download(string url)\n\n\nThis method will create thread and start downloading, and then invoke callback:\n\nvoid callback(char* data)\n\n\nWhat is best: allocate memory for data in Downloader or allocate it out of Downloader class? In first case we will need to copy data returned in callback and if data is big - it is not good, otherwise we will allocate memory in Downloader class and release it somewhere else. In second case we need to allocate memory for data and pass it as parameter in download method:\n\nchar *data = new char[DATA_SIZE];\ndownloader.download(url, data);\n\n\nBut how can we protect this allocated data from changing it from callable thread, while it used by downloader thread.

Then below all that, more fields that belong to the user table.\n\nIf you are following me so far, the problem I am facing is the client wants this to show on a single form not multi page or separated in two forms, the flow must 'look' like a single form (even though the elements will belong to different database tables.\n\nSecond, it is simple enough to have the data put into the contact_info table, however there is no actual user_id generated until the rest of the 'user' fields are filled out and the user record is updated, and therefore, I am failing to see how to add the associative record in user_has_contact_info, without saving the user record first and adding the contact info second.\n\nFinally, the preference is to avoid javascript (though not completely ruled out, because pretty much any solution is going to require either javascript -or- page refreshes with partial form field data retention and possibly even validation and filter issues -- have not gotten that far yet)\n\nSo my ultimate question is, what is the best way to handle many-to-many database table relationships using Zend_Form in the scenario above. I might be overthinking this problem and missing the simple solution here, and look forward to different perspectives.\n\nPlease note, this is not a question about how to design the database, rather how to create the zend form to handle the database the way it is designed." ]
