".NET 3.5CF WebRequest to Slim Framework",
"I'm writing a mobile application in .NET 3.5 Compact Framework and am trying to make a GET request to a PHP Slim Framework page. If I try to access the page from a web browser on the local machine it works, but if I try to access it from the mobile device C# application or the mobile device's web browser I get a HTTP 404. I made a standard PHP page to display the current time and that works on all three of the above, so isolating the problem specifically to Slim pages. I also took a look at the access.log in xampp which looks like this:\n\n[20/Mar/2013:17:07:38 +0000] \"GET /SlimTest/ HTTP/1.1\" 200 21 \"-\" \"Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 2.0.50727; .NET CLR 3.0.04506.648; .NET CLR 3.5.21022)\"\n[20/Mar/2013:17:09:37 +0000] \"GET http://10.0.2.15/SlimTest/ HTTP/1.1\" 404 523 \"-\" \"-\"\n\n\nThe first is from the local machine and the second is from the handheld device and, as you can see, the first request is completed successfully and the latter has a 404 returned to it.\n\nThe Slim PHP code looks like this:\n\n$app->get('/', function () {\n echo \"This is the get route\"; \n});\n\n\nAnd the C# looks like this:\n\nstring webResponse = \"\";\ntry\n{\n HttpWebRequest request = (HttpWebRequest)WebRequest.Create(\"http://10.0.2.15/SlimTest/\");\n WebResponse response = request.GetResponse();\n using (StreamReader streamReader = new StreamReader(response.GetResponseStream()))\n {\n webResponse = streamReader.ReadToEnd();\n }\n}\ncatch (Exception ex)\n{\n MessageBox.Show(ex.Message);\n}\n\n\nIt is important to note that I am not a web developer so I do apologise if it is something glaringly obvious.\n\nSpeed is also of the essence with this project so even if someone could suggest an alternative RESTful PHP framework which has proven to be useful to them, then I'd very much appreciate it.\n\nFinally, just for a quick insight, this project will have a web based application and a handheld mobile application that will communicate with a web service. I'm trying to get the web service written in PHP using slim so that it can be hosted on a Linux box to cut costs. Again, if anyone has any suggestions/alternatives then I'd be equally as grateful.\n\nThanks"

My output PDF file is expected to contain images in several cells. Everything seems okay if I run the application in Netbeans IDE. I try to open the generated PDF file and it's nice. No problem at all.\n\nThen I do the 'Clean and Build' thing so I'll have an application with jar extension. This where the problem is. If I generate the PDF file from this jar-extension-application, the PDF file is corrupted. It says that 'An error occured'. I see the size of the file is (always) 0 bytes. But if I remove the codes for 'adding-images-in-cells' in my source code, the PDF file is not corrupted. It can be opened, but the consequence is my file doesn't contain any image.\n\nMy questions are:\n\n\nAm I possibly doing something wrong in the code so that the error occurs?

"Why might a Web Serial API app work in Windows and Linux but not macOS?",

The Nucleo board communicates using a serial port connection over USB, and I can happily talk to it using a serial terminal program (CoolTerm in my case). The browser app works fine in Windows and Linux, but not in macOS. macOS reports that the serial connection is available, appears to connect and open the port correctly, and starts working, but after sending a few dozen bytes the serial port in the mac appears to freeze, and it doesn't transmit anything more to the Nucleo board.\nThe Web serial app reports all the flags (CTS, DCD, DSR and RI) to be false, both before and after the transmitter stops sending data, but the port is opened with flowControl set to the default "none").\nDoes anyone have any idea why this might be happening and how to get the mac serial port to transmit more than a few dozen bytes?\n(I've observed exactly the same behaviour trying to use python and pyserial: it works in Windows and Linux, but doesn't work in macOS, so I am assuming this is something to do with the macOS serial ports.)\nThe code to open the port and send the data looks like this:\nasync function _serialNewClickConnect() {\n\n // Select the serial port. Note: can add filters here, see web.dev/serial\n _serialPort = await navigator.serial.requestPort();\n\n // Open the serial port.\n await _serialPort.open({ baudRate: 115200, bufferSize: 64 });\n\n // Set up to allow data to be written:\n _serialWriter = _serialPort.writable.getWriter();\n\n // Listen to data coming from the serial device.\n while (_serialPort.readable) {\n\n _serialReader = _serialPort.readable.getReader();\n try {\n while (true) {\n const { value, done } = await _serialReader.read();\n if (done) {\n // To allow the serial port to be closed later:\n _serialReader.releaseLock();\n break;\n }\n if (value) {\n // Something has arrived. This will be stored in value as a uint8 array.\n for (let x = 0; x < value.byteLength; x++) {\n _serialRxData.push(value[x]);\n }\n }\n }\n } catch (error) {\n // TODO: Handle non-fatal read error.\n }\n }\n}\n\nasync function sendString(string) {\n // Sends a string over the serial port.\n const data = new TextEncoder().encode(string);\n await _serialWriter.write(data);\n}"

"Adding to end of Vagrant path",
"I would like to create a generic dev Vagrant environment that I can vagrant up from anywhere on my system. I know that Vagrant searches for a Vagrantfile starting with CWD, then in each parent directory. I also know that setting the VAGRANT_CWD environment variable allows you to tell Vagrant to start searching in a given directory.\n\nSo, I could do something like this: export VAGRANT_CWD=~/.dotfiles/vdevbox, where vdevbox contains the Vagrantfile and other relevant stuff for my dev environment. This allows me me to vagrant up from anywhere, but it takes precedence over Vagrantfiles in my CWD, which makes it impossible to use other Vagrant environments (clearly a fail).\n\nSo, basically I need the Vagrant equivalent of Bash's PATH=$PATH:~/some/path. Is this supported, or is there a better way of meeting this use-case?\n\nEdit to address @arturhoo's answer\n\nThe same help page linked above mentions merging settings via a ~/.vagrant.d/Vagrantfile. I think that this is a different thing than Vagrant's search of dirs for a Vagrantfile to start an env from. I think it's strictly limited to merging settings, and Vagrant must additionally find a Vagrantfile via the search method described above. I tried it, and the results seem to support my hypothesis.\n\n[~/.vagrant.d]$ ls -rc | tail -n 2\nVagrantfile\nbootstrap.sh\n[~/test]$ ls\n[~/test]$ vagrant up\n# Error message about missing Vagrantfile"

"Can one think of \"let\" and other Rust idioms in terms of assembly?",
"When writing in C, it's straightforward to reason about how assignments will look like after compilation. I know Rust is a higher level language that uses functional features, but since it's referred to as a \"system language\" I wonder if that's possible in Rust too.\n\nFor example, I want to loop through an array of integers and calculate the biggest product of 3 adjacent numbers:\n\nunsigned int a[10] = {4, 2, 3, 8, 1, 0, 7, 4, 9, 2};\nunsigned int i, p=1, max=0;\nfor(i=0; i<8; i++, p=1) {\n p = a[i] * a[i+1] * a[i+2];\n if(p>max) max = p;\n}\n\n\nThe equivalent Rust code could look like this (not sure if this is the idiomatic way):\n\nlet a = [4, 2, 3, 8, 1, 0, 7, 4, 9, 2];\nlet mut max = 0;\nfor i in 0..8 {\n let p = a[i] * a[i + 1] * a[i + 2];\n if p > max {\n max = p;\n }\n}\n\n\nIn C, p is a variable that is defined before the loop and is assigned a new value every time; in Rust on the other hand, let p is used within the loop, which is confusing to think about in a procedural way.\n\nIs C closer to assembly code? Or is it possible to reason about Rust just as well?"

"I'm a beginning student in CS, and my classes are mostly in Java. I'm currently going through \"Little Schemer\" as a self study, and in the process of finding out how to do that I have found numerous references to \"implementations\" of Scheme. My question is, what are implementations?\n\nAre they sub-dialects of Scheme, or is that something else (DrScheme seem to allow for different \"flavors\" of the language)? Is it just the name given to any given ecosystem incorporating an IDE, interpreter, interactive tool and the like?\n\nDo all other languages (e.g., Java) also have a variety of \"implementations\", or is it something reserved to \"open\" languages?\n\nThank you,\n\nJoss Delage"

"Difference between CLR 2.0 and CLR 4.0",
"I have read countless blogs, posts and StackOverflow questions about the new features of C# 4.0. Even new WPF 4.0 features have started to come out in the open. What I could not find and will like to know:\n\n\nWhat are the major changes to CLR 4.0 from a C#/WPF developer perspective?\nWhat are the major changes to CLR 4.0 as a whole?\n\n\nI think, internally, most changes are for the new dynamic languages and parallel programming. But are there any other major improvements? Because language improvements are just that, language improvements. You just need the new compiler and those features can be used with a lower version of .Net, apart from version 1.0/1.1 (at least most of them can be used).\n\nAnd if the above features are the only ones, only for these features the version is changed to 4.0, which I think is 4.0 because of being based on .Net 4.0 version (i.e. after 1.0/1.1, 2.0 & 3.0/3.5). Is the version increment justified?\n\nEdited:\n\nAs Pavel Minaev pointed out in the comments, even those two features are CLR independent. There were speed and other improvements in 3.0 and 3.5 also. So why the version increment?"

I have multiple objects that I'd like to move simultaneously when one of the group is dragged. Here is my current situation:\n\n\n\nWhat I'd like to do is when the red circle is moved, the red crosshairs would also move so that they appear to be \"locked\" to the circle. The same with the green circle.\n\nI have been able to accomplish something very close to this by adding the circles and crosshairs to a container, as mentioned in the answers to this question:\n\nEaseljs Scrollable Container\n\nBut the issue I encounter is that the container is actually a rectangle, such that I can click anywhere between the circle and crosshairs to move the various objects contained within the container. Instead I would like for the objects to be moved only when I click on a circle.\n\nDoes anyone have any idea how to accomplish this?

I have experience with foreign keys, but it's my first approach to both Kohana and ORM and I'm not sure really how to define my models there to represent these relations.\n\nWhat I want to be able to do is basically this:\n\n// I'm able to do this.\n$user = ORM::factory('user', 1);\n$user_events = $user->events->find_all();\n$user_summaries = $user->usersummaries->find_all();\n\n// I'm able to do this, too.\n$event = ORM::factory('event', 1);\n$event_users = $event->users->get_all();\n\n// I don't know how to be able to do this:\n$user_event = ORM::factory('userevent', 1);\n$user_details = $user_event->user->find();\n$event_details = $user_event->event->find();\n\n\nMy current models look like this:\n\n# classes/model/user.php\nclass Model_User extends ORM\n{\n protected $_has_many = array(\n 'scores' => array(),\n 'usersummaries' => array(),\n );\n}\n\n# classes/model/event.php\nclass Model_Event extends ORM\n{\n protected $_has_many = array(\n 'scores' => array(),\n 'usersummaries' => array(),\n );\n}\n\n# classes/model/userevent.php\nclass Model_Userevent extends ORM\n{\n protected $_belongs_to = array(\n 'user' => array(),\n 'event' => array(),\n );\n}\n\n# classes/model/usersummary.php\nclass Model_Usersummary extends ORM\n{\n protected $_belongs_to = array(\n 'user' => array(),\n 'event' => array(),\n );\n}\n\n\nCurrently calling:\n\n$user_event = ORM::factory('userevent', 1);\n$user_details = $user_event->user->find();\n\n\nreturns always the first user from users table, even though userevent has different user_id.\nI presume I need to change something in Model_userevent but I'd use with some help.\n\nNB. I'm using Kohana 3.0.8."
