"Adding a developer to an Apple Developer account",
"I have an Apple Developer iOS Membership. I have hired a developer to write an iOS app for me. They said they don't have their own account so in order for us to test the app using ad-hoc provisioning we'll need to use my account. When I go to invite users into my account from the Member Center I am given 2 options to add this user as, 1) Admin, 2) Member. Is the correct way to give a developer access and which option should I give them? I want to give the least amount of privileges as possible. I don't want them to access any sensitive account information, just allow them to develop the app and allow for testing.\n\nThis is the overview of the roles but I am still not sure which is correct\nhttps://developer.apple.com/support/roles/"

"Copy video from my own machine to EC2 server by running scp command (JSCH)",
"I need to SCP a video file from my local machine to a EC2 cloud server using a Java program. I am using the JSCH library to do so.\n\nSo far I can connect to the EC2 server and can run basic commands on it. Following is the code:\n\nimport com.jcraft.jsch.*;\nimport java.io.*;\nimport java.io.IOException;\n\npublic class EC2 \n{\n public static void main(String[] args) throws JSchException, IOException, InterruptedException \n {\n JSch jsch=new JSch();\n jsch.addIdentity(\"yyyy.pem\");\n jsch.setConfig(\"StrictHostKeyChecking\", \"no\");\n\n //enter your own EC2 instance IP here\n Session session=jsch.getSession(\"ec2-user\", \"xx.xxx.xxx.xxx\", 22);\n session.connect();\n\n //run stuff\n String command = \"whoami;hostname\";\n Channel channel = session.openChannel(\"exec\");\n ((ChannelExec) channel).setCommand(command);\n ((ChannelExec) channel).setErrStream(System.err);\n channel.connect();\n\n\n InputStream input = channel.getInputStream();\n //start reading the input from the executed commands on the shell\n byte[] tmp = new byte[1024];\n while (true) \n {\n while (input.available() > 0) \n {\n int i = input.read(tmp, 0, 1024);\n if (i < 0) break;\n System.out.println(new String(tmp, 0, i));\n }\n if (channel.isClosed())\n {\n System.out.println(\"exit-status: \" + channel.getExitStatus());\n break;\n }\n Thread.sleep(1000);\n }\n\n channel.disconnect();\n session.disconnect();\n }\n\n}\n\n\nNow I am aware of the SCP syntax for file transfer . But the thing here is that every command that I now here will be run the EC2 server\nFor eg: String command = \"ls -l\"; Will give me the home file list in the EC2.\n\nSo how do I transfer the video stored on my laptop the home/ec2-user directory of the EC2 ?"

To ensure accurate entry while mitigating clutter (read: without using DataGridViewComboBoxColumn) I have a couple event handlers which temporarily turn a DataGridViewTextBoxCell into an equivalent DataGridViewComboBoxCell connected to values known to be \"clean\" when editing events are raised (typically when an editable cell is clicked):\n\nprivate void OnCellEndEdit(object sender, DataGridViewCellEventArgs e)\n{\n //construct a textbox cell and set to current value\n DataGridViewTextBoxCell cell = new DataGridViewTextBoxCell();\n cell.Value = dataGridView.Rows[e.RowIndex].Cells[e.ColumnIndex].Value;\n\n //color row if invalid or modified\n UpdateRowStyle(dataGridView.Rows[e.RowIndex]);\n\n //switch to the new cell and redraw\n dataGridView.Rows[e.RowIndex].Cells[e.ColumnIndex] = cell;\n dataGridView.Refresh();\n}\n\n\nand\n\nprivate void OnCellBeginEdit(object sender, DataGridViewCellCancelEventArgs e)\n{\n //construct a combobox cell, link to data, and set to current value\n DataGridViewComboBoxCell cell = new DataGridViewComboBoxCell();\n cell.DataSource = mDropDownValues[dataGridView.Columns[e.ColumnIndex].Name];\n cell.Value = dataGridView.Rows[e.RowIndex].Cells[e.ColumnIndex].Value;\n\n //switch to the new cell and redraw\n dataGridView.Rows[e.RowIndex].Cells[e.ColumnIndex] = cell;\n dataGridView.Refresh();\n}\n\n\nMost of the time this works perfectly - the last cell edited reverts to a DataGridViewTextBoxCell containing the newly selected data, and the cell selected for editing becomes a DataGridViewComboBoxCell linked to the data specified in the mDropDownValues[] dictionary. When editing a cell which has row and column indices that are equal, however, I run into trouble. The cell fails to change between the two types, throwing an exception on the dataGridView.Rows[e.RowIndex].Cells[e.ColumnIndex] = cell; line in both event handlers (once when handling CellBeginEdit and then again when handlingCellEndEdit). The exception states\n\n\n \"Operation is not valid because it results in a reentrant call to the SetCurrentCellAddressCore function.\"\n\n\nWhat is causing this error, and why does it only happen when editing the cells along the DataGridView's diagonal?

We have to use JRebel so we don't have to restart the app each time we change a line of code.\n\nEvery time I change one line of code in one .java file, and after invoking the IntelliJ make process on that particular file, JRebel seem to reload a whole bunch of client-side classes. \n\nWith Eclipse, this brutal reloading behavior might happen sometimes, but in most cases the class reloading process is much faster !\n\nI think that I'm missing something. Does anyone with experience using IntelliJ and JRebel know how to have JRebel plugin reload one single class when nothing more is needed ?\n\nAny help would be greatly appreciated ! \n\n\nNote 1 : I know super dev mode could help but I'd like to have the\nJRebel plugin work first.\nNote 2 : the VM arg -Drebel.check_class_hash=true helps too, but I don't think the plugin is meant to work that way."

I read the links [1] and [2] below but there are two points I still don't understand.\nIn [2], he uses the following bash script to write output intermittently and then he uses the piped commands:\n#generator.bash\nfor i in {1..1000}; do\n echo "this is line $i"\n sleep 1\ndone\n\nbash generator.bash | grep --line-buffered line | cut -c 9-\n\nI understand why he had to use --line-buffered with grep, but why doesn't he have to do something similar about the stdout buffer from "bash generator.bash"? I can only imagine that this stdout buffer is line buffered but I couldn't find anything to confirm this.\nAlso, are the stdin buffers of grep and cut line buffered as well? I couldn't find anything to confirm if this is true or not but if it isn't line buffered then what is the point of making the stdout buffer line buffered if the stdin on the other side is block buffered?\n[1] https://www.pixelbeat.org/programming/stdio_buffering/\n[2] https://blog.jpalardy.com/posts/grep-and-output-buffering/"

"Maintaining request scope in Express/Node.js",
"I am using Express to expose a REST API in my Node.js application. When a REST request comes in, I extract the user information from the HTTP headers. I would like this information to be available throughout the life of this request, no matter what function I am in. An obvious but kludgy way is to pass around the user information as parameters to all function calls. Is there a better way? So far I have found the following solutions, but I am not sure if they are ready for prime time:\n\n\nStrongLoop Zone Library: Docs say \"The zone library and documentation are still under development: there are bugs, missing features, and limited documentation.\"\nContinuation-Local Storage: Not sure if this is slated to be part of Node.js.

"How to fix the scroll issue in Bootstrap 4 when one modal is closed and another open immediately after?",
"I have code in my application that requires closing existing modal and immediately opening another modal. The code works fine, but there is a scrolling issue (vertical/horizontal) with the second modal. If I resize my screen and try to scroll vertically only background content is scrolling. I was digging to find the issue and here is what I found. I think there is a time race condition problem. If I put setTime {...some code...,400} that will fix the problem.

"How to properly customize UITabBar and UITabBarItem on iOS 7 and iOS 8?",
"I am googling around so much, but nowhere I find a straight and consolidated answer.\n\nI want to customize myUITabBarController such that:\n\n\nthe UITabBar itself is completely black\nthe text color of the item titles is white in non-highlighted state\nthe text color of the item titles is red in highlighted state\nUse multicolored icons in the tab bar\n\n\n1. Turn UITabBar black\n\nI am guessing I need to use the UIAppearance API for this, and actually I was able to turn the UITbarBar black using: [[UITabBar appearance] setBarTintColor:[UIColor blackColor]];.\n\n2. and 3. Modify color of item titles\n\nHowever, the color of the text items doesn't seem to do what I want, after googling around, the following solutions made sense to me, but it only changes the non-highlighted state to white, highlighted stays white as well...\n\nNSDictionary *titleAttributes = @{NSForegroundColorAttributeName : [UIColor whiteColor]};\n[[UITabBarItem appearance] setTitleTextAttributes:titleAttributes forState:UIControlStateNormal];\n\nUIColor *titleHighlightedColor = [UIColor redColor]; \nNSDictionary *highlightedTitleAttributes = @{NSForegroundColorAttributeName : titleHighlightedColor};\n[[UITabBarItem appearance] setTitleTextAttributes:highlightedTitleAttributes forState:UIControlStateHighlighted];\n\n\n4. Multicolored items\n\nAbout the multicolored icons, so far by approach was to simply set the icons in Storyboards like this:\n\n\n\nBut this doesn't do what I want, it only shows the whole icon in grey when the item is not selected. When the item is selected, the icon completely disappears.\n\nThis is the original icon:\n\n\n\nThis is how it looks when the item is not selected:\n\n\n\nAnd here it is in the selected stated, as mentioned the icon completely disappears:\n\n\n\nSo, my question is how precisely I can achieve the above mentioned requirements. What am I currently missing? Am I better off doing everything in code than in Storyboards?\n\nNote: I am targeting iOS versions greater than 7.0, so please include any version specific information if the behaviour differs between iOS 7 and iOS 8."
