I want to add to my current "genimage.cfg" new partition "logs". So I added lines like bellow to my config file:
File "genimage.cfg":
image boot.vfat {
vfat {
files = {
"MLO",
"u-boot.img",
"uEnv.txt"
}
}
size = 2M
}
image sdcard.img {
hdimage {
}
partition boot {
partition-type = 0xC
bootable = "true"
image = "boot.vfat"
}
partition rootfs {
partition-type = 0x83
image = "rootfs.ext4"
}
partition home {
partition-type = 0x83
image = "home.ext3"
}
partition logs {
partition-type = 0x83
image = "logs.ext4"
}
}
image home.ext3 {
name = "home"
ext3 {}
size = 240M
}
image logs.ext4 {
name = "logs"
ext4 {}
size = 64M
}
But I got error during build image:
genext2fs: couldn't allocate a block (no free space)
hdimage(sdcard.img): could not generate logs.ext4
hdimage(sdcard.img): failed to generate sdcard.img
Makefile:625: recipe for target 'target-post-image' failed
What could I do to fix this error? The error is only related to the "logs" partition and its image because without them the image is built

I currently have images which the image name is returned by a function and is dynamically called based on a variable like this:
String _setImage() {
if (currentQuestion > 1 && currentQuestion < 11) {
return "assets/images/image_$intensityIndex.png";
} else {
return "assets/images/image.png";
}
}
I want to switch to preloading the images and I am using the technique described at Preload images in a stateful widget on Flutter, but I am not sure how to have the function return an image which the name is dynamically determined based on another variable. Here is what I have so far:
void initState() {
super.initState();
image0 = Image.asset('assets/images/image_0.png');
image1 = Image.asset('assets/images/image_1.png');
image2 = Image.asset('assets/images/image_2.png');
image3 = Image.asset('assets/images/image_3.png');
}
void didChangeDependencies() {
super.didChangeDependencies();
precacheImage(image0.image, context);
precacheImage(image1.image, context);
precacheImage(image2.image, context);
precacheImage(image3.image, context);
}
Image _setImage() {
if (currentQuestion > 1 && currentQuestion < 11) {
return ______________;
} else {
return image0;
}
}
All help is appreciated!

You don't need to return with precach because if you use exact image that you cache.
Ex:
precacheImage('assets/images/image_1.png'); // if this is the image name
Image.asset('assets/images/image_1.png'); // when you use this it is getting from the cache but the path should be same.
If I explain it another way:
precacheImage("assets/images/image_$intensityIndex.png"); // image_1.png
Image.asset('assets/images/image_1.png'); // when you do this, asset taking from the cache by looking at the path.
I dont find a way to override root size device using block_device_mappings in aws_launch_template with terraform aws.
I know I can specify an extra volume size doing for example:
block_device_mappings {
device_name = "/dev/xvda"
ebs {
volume_size = "${var.frontend_kong_volume_size}"
volume_type = "${var.frontend_kong_volume_type}"
delete_on_termination = "true"
}
}
but I get a new disk in the VM with those specifications.
But what I want to do is resize the root disk.
Can you help me to figure out how to do it?
Thanks.
block_device_mappings is for additional block devices.
You have to know device where root device mounted. for example for centos 7 AMI it's /dev/sda1
resource "aws_launch_template" "foobar" {
name_prefix = "foobar"
image_id = "ami-9887c6e7"
instance_type = "t2.micro"
block_device_mappings {
device_name = "/dev/sda1"
ebs {
volume_size = 40
}
}
}
resource "aws_autoscaling_group" "bar" {
availability_zones = ["us-east-1a"]
desired_capacity = 1
max_size = 1
min_size = 1
launch_template = {
id = "${aws_launch_template.foobar.id}"
version = "$$Latest"
}
}
But remember that update of volume size in terraform will not take effect to running instances. So you will have to replace instances to increase volume size.
I am working with Xamarin.iOS. I use UIImagePickerController to record video . Now I get the filePath of the video in sandBox . But I want to calculate the size of the video before I upload(over 20M will be banned) . I'm not familiar with native iOS(OC and Swift).I can only get the duration. So , how to get the size(in MB) of the video?
You can use the Class NSFileManager .Try to refer to the following code:
public double GetFileSize(NSString filepath)
{
NSFileManager fileManager = NSFileManager.DefaultManager;
double filesize = -1.0;
if (fileManager.FileExists(filepath))
{
filesize = (double)fileManager.GetAttributes(filepath).Size;
return filesize / (1024 * 1024); // return the size as MB
}
else
{
Console.Write("file can not be found");
return 0;
}
}
I am playing a video with mediaelement.js. Works fine but when I want to change the source of the video I get an error:
SCRIPT438: Object doesn't support property or method 'setSrc'
Anyone an idea how to fix this?
code:
function playVideo(source) {
var fileformat:string
player.pause();
if (Modernizr.video) {
fileformat = ".mp4";
} else {
fileformat = ".flv";
}
var sources = [
{ src: 'media/'+ source + fileformat }
];
player.setSrc(sources);
player.load();
player.play();
}
in my app i have a list of picture. I would like to determine the size of the single images but not have property.
using (MediaLibrary library = new MediaLibrary())
{
CameraRollAlbum = library.RootPictureAlbum.Albums.First((album) => album.Name == "Camera Roll");
List<Picture> pictures = CameraRollAlbum.Pictures.Tolist();
foreach (Picture pic in pictures)
{
pic.size?? pic.length??
}
}
Get the Image Stream eval the size:
foreach (Picture pic in pictures)
{
var sizeInKb = pic.GetImage().Length / 1024;
}
