There is an annual limit on the amount of personal earnings that subject to payroll, or Social Security tax. Above that amount, payroll taxes are no longer applied to one's earnings. This same limit is applied to how much of one's earnings can be applied to their benefit calculation. For {{MAX_CAP_YEAR}}, this limit is ${{MAX_CAP | number:0}}. Earnings above that amount are not subject to payroll tax, and do not affect your social security benefit, PIA, or AIME.
This cap is updated every year to account for wage growth. In the following table, you can see the cap for every year since 1956:
The cap for years 1937 - 1974 and for 1979 - 1981 was set by statute. The cap for all other years is set by an automatic calculation as specified by the Social Security Act.
The formula for a given year X takes the National Average Wage Index (AWI) for year (X - 2), divides this by $22,935.42 which was the AWI in 1992, and multiplies it by $60,600 which was the cap in 1994.
Useful Links:
Look at your personal benefit data find out how it will compare to these maximums.
Ask other 'What If?' questions. The tool is absolutely free.

Recipe: No-grief gravy can be made in advance | Honolulu Star-Advertiser
Sure, you can make your Thanksgiving gravy the traditional way from the turkey pan drippings. It’s great if you want to do that and have the time.
But sometimes making gravy can bring grief — when you end up with a greasy, lumpy mess, instead of a glossy, smooth gravy.
I’ve resolved to always make gravy in advance. It gives me a head start on dinner, and I love how it turns out.
Over the years, I’ve tweaked the recipe a bit — one of the most important added steps involves de-fatting the strained broth by putting it in the freezer. On Thanksgiving Day, if you don’t want to waste the pan drippings from your cooked turkey, add them to the gravy to enhance the flavor.
MAKE THIS gravy up to 3 days in advance. It can also be frozen. The consistency is thick, but can be thinned with turkey drippings.
MAKE-AHEAD TURKEY GRAVY
By Susan Selasky
- 4 turkey wings (3 to 4 pounds)
- 2 medium sweet onions, peeled, cut up
- 1 cup water
- 8 cups low-sodium, fat-free chicken broth, divided
- 1 large chopped carrot
- 1/2 teaspoon dried thyme (optional)
- 3/4 cup all-purpose flour
- 1 to 2 tablespoons unsalted butter
- 1/2 teaspoon freshly ground pepper
Heat oven to 400 degrees.
Place turkey wings in roasting pan; scatter onions on top. Roast 75 minutes, or until wings are golden brown.
Put wings and onions in large stockpot. Add water to roasting pan; stir to scrape up any brown bits on bottom and add to pot. Add 6 cups broth (refrigerate remaining 2 cups), carrot and thyme, if using. Simmer, uncovered, 90 minutes.
Remove wings and let cool. Remove and discard skin; reserve meat for another use.
Strain broth into fat separator or into a bowl.  Pour de-fatted broth into a saucepan. (Or, put bowl in freezer. The fat will rise to the top and become solid. What’s left underneath will be jelled, which is what you want. Place jelled broth in saucepan.)
Bring broth to gentle boil. Remove 2 cups reserved broth from refrigerator and stir in flour until well blended and smooth. Whisk mixture into broth in saucepan and cook 5 minutes to thicken gravy and cook out the raw flour taste. Stir in butter and season with pepper. Add fat-skimmed drippings from a freshly roasted turkey, if desired. Makes about 8 cups.
>> NOTE: Gravy may be frozen up to a month. Thaw and reheat.

OUTPUT_FILENAME is the destination disk image filename.
OUTPUT_FMT is the destination format.
OPTIONS is a comma separated list of format specific options in a
name=value format. Use -o ?
for an overview of the options supported
by the used format or see the format descriptions below for details.
SNAPSHOT_PARAM is param used for internal snapshot, format is ‘snapshot.id=[ID],snapshot.name=[NAME]’ or ‘[ID_OR_NAME]’.
-
--object
OBJECTDEF
¶ is a QEMU user creatable object definition. See the qemu(1) manual page for a description of the object properties. The most common object type is a
secret
, which is used to supply passwords and/or encryption keys.
-
--image-opts
¶
Indicates that the source FILENAME parameter is to be interpreted as a full option string, not a plain filename. This parameter is mutually exclusive with the -f parameter.
-
--target-image-opts
¶
Indicates that the OUTPUT_FILENAME parameter(s) are to be interpreted as a full option string, not a plain filename. This parameter is mutually exclusive with the -O parameters. It is currently required to also use the -n parameter to skip image creation. This restriction may be relaxed in a future release.
If specified,
qemu-img
will open the image in shared mode, allowing other QEMU processes to open it in write mode. For example, this can be used to get the image information (with ‘info’ subcommand) when the image is used by a running guest. Note that this could produce inconsistent results because of concurrent metadata changes, etc. This option is only allowed when opening images in read-only mode.
-
--backing-chain
¶
Will enumerate information about backing files in a disk image chain. Refer below for further description.
-
-c
¶
Indicates that target image must be compressed (qcow format only).
-
-h
¶
With or without a command, shows help and lists the supported formats.
-
-p
¶
Display progress bar (compare, convert and rebase commands only). If the -p option is not used for a command that supports it, the progress is reported when the process receives a
SIGUSR1
orSIGINFO
signal.
-
-q
¶
Quiet mode - do not print any output (except errors). There’s no progress bar in case both -q and -p options are used.
-
-S
SIZE
¶ Indicates the consecutive number of bytes that must contain only zeros for qemu-img to create a sparse image during conversion. This value is rounded down to the nearest 512 bytes. You may use the common size suffixes like
k
for kilobytes.
-
-t
CACHE
¶ Specifies the cache mode that should be used with the (destination) file. See the documentation of the emulator’s
-drive cache=...
option for allowed values.
-
-T
SRC_CACHE
¶ Specifies the cache mode that should be used with the source file(s). See the documentation of the emulator’s
-drive cache=...
option for allowed values.
Parameters to compare subcommand:
-
-f
¶
First image format
-
-F
¶
Second image format
-
-s
¶
Strict mode - fail on different image size or sector allocation
Parameters to convert subcommand:
-
--bitmaps
¶
Additionally copy all persistent bitmaps from the top layer of the source
-
-n
¶
Skip the creation of the target volume
-
-m
¶
Number of parallel coroutines for the convert process
-
-W
¶
Allow out-of-order writes to the destination. This option improves performance, but is only recommended for preallocated devices like host devices or other raw block devices.
-
-C
¶
Try to use copy offloading to move data from source image to target. This may improve performance if the data is remote, such as with NFS or iSCSI backends, but will not automatically sparsify zero sectors, and may result in a fully allocated target image depending on the host support for getting allocation information.
-
--salvage
¶
Try to ignore I/O errors when reading. Unless in quiet mode (
-q
), errors will still be printed. Areas that cannot be read from the source will be treated as containing only zeroes.
-
--target-is-zero
¶
Assume that reading the destination image will always return zeros. This parameter is mutually exclusive with a destination image that has a backing file. It is required to also use the
-n
parameter to skip image creation.
Parameters to dd subcommand:
-
bs
=BLOCK_SIZE
¶ Defines the block size
-
count

Command description:
-
amend
[--object OBJECTDEF] [--image-opts] [-p] [-q] [-f FMT] [-t CACHE] [--force] -o OPTIONS FILENAME
¶ Amends the image format specific OPTIONS for the image file FILENAME. Not all file formats support this operation.
The set of options that can be amended are dependent on the image format, but note that amending the backing chain relationship should instead be performed with
qemu-img rebase
.–force allows some unsafe operations. Currently for -f luks, it allows to erase the last encryption key, and to overwrite an active encryption key.
-
bench
[-c COUNT] [-d DEPTH] [-f FMT] [--flush-interval=FLUSH_INTERVAL] [-i AIO] [-n] [--no-drain] [-o OFFSET] [--pattern=PATTERN] [-q] [-s BUFFER_SIZE] [-S STEP_SIZE] [-t CACHE] [-w] [-U] FILENAME
¶ Run a simple sequential I/O benchmark on the specified image. If
-w
is specified, a write test is performed, otherwise a read test is performed.A total number of COUNT I/O requests is performed, each BUFFER_SIZE bytes in size, and with DEPTH requests in parallel. The first request starts at the position given by OFFSET, each following request increases the current position by STEP_SIZE. If STEP_SIZE is not given, BUFFER_SIZE is used for its value.
If FLUSH_INTERVAL is specified for a write test, the request queue is drained and a flush is issued before new writes are made whenever the number of remaining requests is a multiple of FLUSH_INTERVAL. If additionally
--no-drain
is specified, a flush is issued without draining the request queue first.if
-i
is specified, AIO option can be used to specify different AIO backends:threads
,native
orio_uring
.If
-n
is specified, the native AIO backend is used if possible. On Linux, this option only works if-t none
or-t directsync
is specified as well.For write tests, by default a buffer filled with zeros is written. This can be overridden with a pattern byte specified by PATTERN.
-
bitmap
(--merge SOURCE | --add | --remove | --clear | --enable | --disable)... [-b SOURCE_FILE [-F SOURCE_FMT]] [-g GRANULARITY] [--object OBJECTDEF] [--image-opts | -f FMT] FILENAME BITMAP
¶ Perform one or more modifications of the persistent bitmap BITMAP in the disk image FILENAME. The various modifications are:
--add
to create BITMAP, enabled to record future edits.--remove
to remove BITMAP.--clear
to clear BITMAP.--enable
to change BITMAP to start recording future edits.--disable
to change BITMAP to stop recording future edits.--merge
to merge the contents of the SOURCE bitmap into BITMAP.Additional options include
-g
which sets a non-default GRANULARITY for--add
, and-b
and-F
which select an alternative source file for all SOURCE bitmaps used by--merge
.To see what bitmaps are present in an image, use
qemu-img info
.
-
check
[--object OBJECTDEF] [--image-opts] [-q] [-f FMT] [--output=OFMT] [-r [leaks | all]] [-T SRC_CACHE] [-U] FILENAME
¶ Perform a consistency check on the disk image FILENAME. The command can output in the format OFMT which is either
human
orjson
. The JSON output is an object of QAPI typeImageCheck
.If
-r
is specified, qemu-img tries to repair any inconsistencies found during the check.-r leaks
repairs only cluster leaks, whereas-r all
fixes all kinds of errors, with a higher risk of choosing the wrong fix or hiding corruption that has already occurred.Only the formats
qcow2
,qed
andvdi
support consistency checks.In case the image does not have any inconsistencies, check exits with
0
. Other exit codes indicate the kind of inconsistency found or if another error occurred. The following table summarizes all exit codes of the check subcommand:- 0
Check completed, the image is (now) consistent
- 1
Check not completed because of internal errors
- 2
Check completed, image is corrupted
- 3
Check completed, image has leaked clusters, but is not corrupted
- 63
Checks are not supported by the image format
If
-r
is specified, exit codes representing the image state refer to the state after (the attempt at) repairing it. That is, a successful-r all
will yield the exit code 0, independently of the image state before.
-
commit
[--object OBJECTDEF] [--image-opts] [-q] [-f FMT] [-t CACHE] [-b BASE] [-d] [-p] FILENAME
¶ Commit the changes recorded in FILENAME in its base image or backing file. If the backing file is smaller than the snapshot, then the backing file will be resized to be the same size as the snapshot. If the snapshot is smaller than the backing file, the backing file will not be truncated. If you want the backing file to match the size of the smaller snapshot, you can safely truncate it yourself once the commit operation successfully completes.
The image FILENAME is emptied after the operation has succeeded. If you do not need FILENAME afterwards and intend to drop it, you may skip emptying FILENAME by specifying the
-d
flag.If the backing chain of the given image file FILENAME has more than one layer, the backing file into which the changes will be committed may be specified as BASE (which has to be part of FILENAME’s backing chain). If BASE is not specified, the immediate backing file of the top image (which is FILENAME) will be used. Note that after a commit operation all images between BASE and the top image will be invalid and may return garbage data when read. For this reason,
-b
implies-d
(so that the top image stays valid).
-
compare
[--object OBJECTDEF] [--image-opts] [-f FMT] [-F FMT] [-T SRC_CACHE] [-p] [-q] [-s] [-U] FILENAME1 FILENAME2
¶ Check if two images have the same content. You can compare images with different format or settings.
The format is probed unless you specify it by
-f
(used for FILENAME1) and/or-F
(used for FILENAME2) option.By default, images with different size are considered identical if the larger image contains only unallocated and/or zeroed sectors in the area after the end of the other image. In addition, if any sector is not allocated in one image and contains only zero bytes in the second one, it is evaluated as equal. You can use Strict mode by specifying the
-s
option. When compare runs in Strict mode, it fails in case image size differs or a sector is allocated in one image and is not allocated in the second one.By default, compare prints out a result message. This message displays information that both images are same or the position of the first different byte. In addition, result message can report different image size in case Strict mode is used.
Compare exits with
0
in case the images are equal and with1
in case the images differ. Other exit codes mean an error occurred during execution and standard error output should contain an error message. The following table sumarizes all exit codes of the compare subcommand:- 0
Images are identical
- 1
Images differ
- 2
Error on opening an image
- 3
Error on checking a sector allocation
- 4
Error on reading data
-
convert
[--object OBJECTDEF] [--image-opts] [--target-image-opts] [--target-is-zero] [--bitmaps] [-U] [-C] [-c] [-p] [-q] [-n] [-f FMT] [-t CACHE] [-T SRC_CACHE] [-O OUTPUT_FMT] [-B BACKING_FILE] [-o OPTIONS] [-l SNAPSHOT_PARAM] [-S SPARSE_SIZE] [-m NUM_COROUTINES] [-W] FILENAME [FILENAME2 [...]] OUTPUT_FILENAME
¶ Convert the disk image FILENAME or a snapshot SNAPSHOT_PARAM to disk image OUTPUT_FILENAME using format OUTPUT_FMT. It can be optionally compressed (
-c
option) or use any format specific options like encryption (-o
option).Only the formats
qcow
andqcow2
support compression. The compression is read-only. It means that if a compressed sector is rewritten, then it is rewritten as uncompressed data.Image conversion is also useful to get smaller image when using a growable format such as
qcow
: the empty sectors are detected and suppressed from the destination image.SPARSE_SIZE indicates the consecutive number of bytes (defaults to 4k) that must contain only zeros for qemu-img to create a sparse image during conversion. If SPARSE_SIZE is 0, the source will not be scanned for unallocated or zero sectors, and the destination image will always be fully allocated.
You can use the BACKING_FILE option to force the output image to be created as a copy on write image of the specified base image; the BACKING_FILE should have the same content as the input’s base image, however the path, image format, etc may differ.
If a relative path name is given, the backing file is looked up relative to the directory containing OUTPUT_FILENAME.
If the
-n
option is specified, the target volume creation will be skipped. This is useful for formats such asrbd
if the target volume has already been created with site specific options that cannot be supplied through qemu-img.Out of order writes can be enabled with
-W
to improve performance. This is only recommended for preallocated devices like host devices or other raw block devices. Out of order write does not work in combination with creating compressed images.NUM_COROUTINES specifies how many coroutines work in parallel during the convert process (defaults to 8).
-
create
[--object OBJECTDEF] [-q] [-f FMT] [-b BACKING_FILE] [-F BACKING_FMT] [-u] [-o OPTIONS] FILENAME [SIZE]
¶ Create the new disk image FILENAME of size SIZE and format FMT. Depending on the file format, you can add one or more OPTIONS that enable additional features of this format.
If the option BACKING_FILE is specified, then the image will record only the differences from BACKING_FILE. No size needs to be specified in this case. BACKING_FILE will never be modified unless you use the
commit
monitor command (or qemu-img commit).If a relative path name is given, the backing file is looked up relative to the directory containing FILENAME.
Note that a given backing file will be opened to check that it is valid. Use the
-u
option to enable unsafe backing file mode, which means that the image will be created even if the associated backing file cannot be opened. A matching backing file must be created or additional options be used to make the backing file specification valid when you want to use an image created this way.The size can also be specified using the SIZE option with
-o
, it doesn’t need to be specified separately in this case.
-
dd
[--image-opts] [-U] [-f FMT] [-O OUTPUT_FMT] [bs=BLOCK_SIZE] [count=BLOCKS] [skip=BLOCKS] if=INPUT of=OUTPUT
¶ dd copies from INPUT file to OUTPUT file converting it from FMT format to OUTPUT_FMT format.
The data is by default read and written using blocks of 512 bytes but can be modified by specifying BLOCK_SIZE. If count=BLOCKS is specified dd will stop reading input after reading BLOCKS input blocks.
The size syntax is similar to dd(1)’s size syntax.
-
info
[--object OBJECTDEF] [--image-opts] [-f FMT] [--output=OFMT] [--backing-chain] [-U] FILENAME
¶ Give information about the disk image FILENAME. Use it in particular to know the size reserved on disk which can be different from the displayed size. If VM snapshots are stored in the disk image, they are displayed too.
If a disk image has a backing file chain, information about each disk image in the chain can be recursively enumerated by using the option
--backing-chain
.For instance, if you have an image chain like:
base.qcow2 <- snap1.qcow2 <- snap2.qcow2
To enumerate information about each disk image in the above chain, starting from top to base, do:
qemu-img info --backing-chain snap2.qcow2
The command can output in the format OFMT which is either
human
orjson
. The JSON output is an object of QAPI typeImageInfo
; with--backing-chain
, it is an array ofImageInfo
objects.--output=human
reports the following information (for every image in the chain):- image
The image file name
- file format
The image format
- virtual size
The size of the guest disk
- disk size
How much space the image file occupies on the host file system (may be shown as 0 if this information is unavailable, e.g. because there is no file system)
- cluster_size
Cluster size of the image format, if applicable
- encrypted
Whether the image is encrypted (only present if so)
- cleanly shut down
This is shown as
no
if the image is dirty and will have to be auto-repaired the next time it is opened in qemu.- backing file
The backing file name, if present
- backing file format
The format of the backing file, if the image enforces it
- Snapshot list
A list of all internal snapshots
- Format specific information
Further information whose structure depends on the image format. This section is a textual representation of the respective
ImageInfoSpecific*
QAPI object (e.g.ImageInfoSpecificQCow2
for qcow2 images).
-
map
[--object OBJECTDEF] [--image-opts] [-f FMT] [--start-offset=OFFSET] [--max-length=LEN] [--output=OFMT] [-U] FILENAME
¶ Dump the metadata of image FILENAME and its backing file chain. In particular, this commands dumps the allocation state of every sector of FILENAME, together with the topmost file that allocates it in the backing file chain.
Two option formats are possible. The default format (
human
) only dumps known-nonzero areas of the file. Known-zero parts of the file are omitted altogether, and likewise for parts that are not allocated throughout the chain.qemu-img
output will identify a file from where the data can be read, and the offset in the file. Each line will include four fields, the first three of which are hexadecimal numbers. For example the first line of:Offset Length Mapped to File 0 0x20000 0x50000 /tmp/overlay.qcow2 0x100000 0x10000 0x95380000 /tmp/backing.qcow2
means that 0x20000 (131072) bytes starting at offset 0 in the image are available in /tmp/overlay.qcow2 (opened in
raw
format) starting at offset 0x50000 (327680). Data that is compressed, encrypted, or otherwise not available in raw format will cause an error ifhuman
format is in use. Note that file names can include newlines, thus it is not safe to parse this output format in scripts.The alternative format
json
will return an array of dictionaries in JSON format. It will include similar information in thestart
,length
,offset
fields; it will also include other more specific information:whether the sectors contain actual data or not (boolean field
data
; if false, the sectors are either unallocated or stored as optimized all-zero clusters);whether the data is known to read as zero (boolean field
zero
);in order to make the output shorter, the target file is expressed as a
depth
; for example, a depth of 2 refers to the backing file of the backing file of FILENAME.
In JSON format, the
offset
field is optional; it is absent in cases wherehuman
format would omit the entry or exit with an error. Ifdata
is false and theoffset
field is present, the corresponding sectors in the file are not yet in use, but they are preallocated.For more information, consult
include/block/block.h
in QEMU’s source code.
-
measure
[--output=OFMT] [-O OUTPUT_FMT] [-o OPTIONS] [--size N | [--object OBJECTDEF] [--image-opts] [-f FMT] [-l SNAPSHOT_PARAM] FILENAME]
¶ Calculate the file size required for a new image. This information can be used to size logical volumes or SAN LUNs appropriately for the image that will be placed in them. The values reported are guaranteed to be large enough to fit the image. The command can output in the format OFMT which is either
human
orjson
. The JSON output is an object of QAPI typeBlockMeasureInfo
.If the size N is given then act as if creating a new empty image file using
qemu-img create
. If FILENAME is given then act as if converting an existing image file usingqemu-img convert
. The format of the new file is given by OUTPUT_FMT while the format of an existing file is given by FMT.A snapshot in an existing image can be specified using SNAPSHOT_PARAM.
The following fields are reported:
required size: 524288 fully allocated size:<PHONE_NUMBER> bitmaps size: 0
The
required size
is the file size of the new image. It may be smaller than the virtual disk size if the image format supports compact representation.The
fully allocated size
is the file size of the new image once data has been written to all sectors. This is the maximum size that the image file can occupy with the exception of internal snapshots, dirty bitmaps, vmstate data, and other advanced image format features.The
bitmaps size
is the additional size required in order to copy bitmaps from a source image in addition to the guest-visible data; the line is omitted if either source or destination lacks bitmap support, or 0 if bitmaps are supported but there is nothing to copy.
-
snapshot
[--object OBJECTDEF] [--image-opts] [-U] [-q] [-l | -a SNAPSHOT | -c SNAPSHOT | -d SNAPSHOT] FILENAME
¶ List, apply, create or delete snapshots in image FILENAME.
-
rebase
[--object OBJECTDEF] [--image-opts] [-U] [-q] [-f FMT] [-t CACHE] [-T SRC_CACHE] [-p] [-u] -b BACKING_FILE [-F BACKING_FMT] FILENAME
¶ Changes the backing file of an image. Only the formats
qcow2
andqed
support changing the backing file.The backing file is changed to BACKING_FILE and (if the image format of FILENAME supports this) the backing file format is changed to BACKING_FMT. If BACKING_FILE is specified as “” (the empty string), then the image is rebased onto no backing file (i.e. it will exist independently of any backing file).
If a relative path name is given, the backing file is looked up relative to the directory containing FILENAME.
CACHE specifies the cache mode to be used for FILENAME, whereas SRC_CACHE specifies the cache mode for reading backing files.
There are two different modes in which
rebase
can operate:- Safe mode
This is the default mode and performs a real rebase operation. The new backing file may differ from the old one and qemu-img rebase will take care of keeping the guest-visible content of FILENAME unchanged.
In order to achieve this, any clusters that differ between BACKING_FILE and the old backing file of FILENAME are merged into FILENAME before actually changing the backing file.
Note that the safe mode is an expensive operation, comparable to converting an image. It only works if the old backing file still exists.
- Unsafe mode
qemu-img uses the unsafe mode if
-u
is specified. In this mode, only the backing file name and format of FILENAME is changed without any checks on the file contents. The user must take care of specifying the correct new backing file, or the guest-visible content of the image will be corrupted.This mode is useful for renaming or moving the backing file to somewhere else. It can be used without an accessible old backing file, i.e. you can use it to fix an image whose backing file has already been moved/renamed.
You can use
rebase
to perform a “diff” operation on two disk images. This can be useful when you have copied or cloned a guest, and you want to get back to a thin image on top of a template or base image.Say that
base.img
has been cloned asmodified.img
by copying it, and that themodified.img
guest has run so there are now some changes compared tobase.img
. To construct a thin image calleddiff.qcow2
that contains just the differences, do:qemu-img create -f qcow2 -b modified.img diff.qcow2 qemu-img rebase -b base.img diff.qcow2
At this point,
modified.img
can be discarded, sincebase.img + diff.qcow2
contains the same information.
-
resize
[--object OBJECTDEF] [--image-opts] [-f FMT] [--preallocation=PREALLOC] [-q] [--shrink] FILENAME [+ | -]SIZE
¶ Change the disk image as if it had been created with SIZE.
Before using this command to shrink a disk image, you MUST use file system and partitioning tools inside the VM to reduce allocated file systems and partition sizes accordingly. Failure to do so will result in data loss!
When shrinking images, the
--shrink
option must be given. This informs qemu-img that the user acknowledges all loss of data beyond the truncated image’s end.After using this command to grow a disk image, you must use file system and partitioning tools inside the VM to actually begin using the new space on the device.
When growing an image, the
--preallocation
option may be used to specify how the additional image area should be allocated on the host. See the format description in the Notes section which values are allowed. Using this option may result in slightly more data being allocated than necessary.
Notes¶
Supported image file formats:
raw
Raw disk image format (default). This format has the advantage of being simple and easily exportable to all other emulators. If your file system supports holes (for example in ext2 or ext3 on Linux or NTFS on Windows), then only the written sectors will reserve space. Use
qemu-img info
to know the real size used by the image orls -ls
on Unix/Linux.Supported options:
preallocation
Preallocation mode (allowed values:
off
,falloc
,full
).falloc
mode preallocates space for image by callingposix_fallocate()
.full
mode preallocates space for image by writing data to underlying storage. This data may or may not be zero, depending on the storage location.
qcow2
QEMU image format, the most versatile format. Use it to have smaller images (useful if your filesystem does not supports holes, for example on Windows), optional AES encryption, zlib based compression and support of multiple VM snapshots.
Supported options:
compat
Determines the qcow2 version to use.
compat=0.10
uses the traditional image format that can be read by any QEMU since 0.10.compat=1.1
enables image format extensions that only QEMU 1.1 and newer understand (this is the default). Amongst others, this includes zero clusters, which allow efficient copy-on-read for sparse images.backing_file
File name of a base image (see
create
subcommand)backing_fmt
Image format of the base image
encryption
If this option is set to
on
, the image is encrypted with 128-bit AES-CBC.The use of encryption in qcow and qcow2 images is considered to be flawed by modern cryptography standards, suffering from a number of design problems:
The AES-CBC cipher is used with predictable initialization vectors based on the sector number. This makes it vulnerable to chosen plaintext attacks which can reveal the existence of encrypted data.
The user passphrase is directly used as the encryption key. A poorly chosen or short passphrase will compromise the security of the encryption.
In the event of the passphrase being compromised there is no way to change the passphrase to protect data in any qcow images. The files must be cloned, using a different encryption passphrase in the new file. The original file must then be securely erased using a program like shred, though even this is ineffective with many modern storage technologies.
Initialization vectors used to encrypt sectors are based on the guest virtual sector number, instead of the host physical sector. When a disk image has multiple internal snapshots this means that data in multiple physical sectors is encrypted with the same initialization vector. With the CBC mode, this opens the possibility of watermarking attacks if the attack can collect multiple sectors encrypted with the same IV and some predictable data. Having multiple qcow2 images with the same passphrase also exposes this weakness since the passphrase is directly used as the key.
Use of qcow / qcow2 encryption is thus strongly discouraged. Users are recommended to use an alternative encryption technology such as the Linux dm-crypt / LUKS system.
cluster_size
Changes the qcow2 cluster size (must be between 512 and 2M). Smaller cluster sizes can improve the image file size whereas larger cluster sizes generally provide better performance.
preallocation
Preallocation mode (allowed values:
off
,metadata
,falloc
,full
). An image with preallocated metadata is initially larger but can improve performance when the image needs to grow.falloc
andfull
preallocations are like the same options ofraw
format, but sets up metadata also.lazy_refcounts
If this option is set to
on
, reference count updates are postponed with the goal of avoiding metadata I/O and improving performance. This is particularly interesting withcache=writethrough
which doesn’t batch metadata updates. The tradeoff is that after a host crash, the reference count tables must be rebuilt, i.e. on the next open an (automatic)qemu-img check -r all
is required, which may take some time.This option can only be enabled if
compat=1.1
is specified.nocow
If this option is set to
on
, it will turn off COW of the file. It’s only valid on btrfs, no effect on other file systems.Btrfs has low performance when hosting a VM image file, even more when the guest on the VM also using btrfs as file system. Turning off COW is a way to mitigate this bad performance. Generally there are two ways to turn off COW on btrfs:
Disable it by mounting with nodatacow, then all newly created files will be NOCOW
For an empty file, add the NOCOW file attribute. That’s what this option does.
Note: this option is only valid to new or empty files. If there is an existing file which is COW and has data blocks already, it couldn’t be changed to NOCOW by setting
nocow=on
. One can issuelsattr filename
to check if the NOCOW flag is set or not (Capital ‘C’ is NOCOW flag).
Other
QEMU also supports various other image file formats for compatibility with older QEMU versions or other hypervisors, including VMDK, VDI, VHD (vpc), VHDX, qcow1 and QED. For a full list of supported formats see
qemu-img --help
. For a more detailed description of these formats, see the QEMU block drivers reference documentation.The main purpose of the block drivers for these formats is image conversion. For running VMs, it is recommended to convert the disk images to either raw or qcow2 in order to achieve good performance.

Amazon is now selling Google’s Pixel 3a and 3a XL starting at just $299
by Maren EstradaAt its full price of just $399, the Google Pixel 3a is the single best-selling unlocked smartphone on Amazon’s entire site. Honestly, we would be shocked if that wasn’t the case. The Pixel 3a is an absolutely incredible value at that price, and there’s really nothing else out there that can touch it.  The nation’s top online retailer just slashed $100 off the price of the Pixel 3a, cutting it to the unmissable price of just $299. The larger Google Pixel 3a XL is $100 off as well, so you can pick one up for $379.99 if you hurry!

Understanding results in RadarGun 2
Introduction
The goal of this document is to describe the way how stress test results should be interpreted in RadarGun 2.x. Artificial scenario of 2 different products (Product 1, Product 2) will be used with the following characteristics:
- Simple stress test (basic-operations-test) performing GET and PUT operations in ratio 4:1
- Test duration - 60s
BasicOperations.Get
| Configuration stress-test | requests | errors | mean | std.dev | net operation throughput |
|---|---|---|---|---|---|
| Product 1 / Cluster[default=4] | 6295856 | 0 | 530.13 us | 668.76 us | 104913 reqs/s |
| Product 2 / Cluster[default=4] | 2839287 | 0 | 344.5 us | 5.87 ms | 46816 reqs/s |
At first sight the results might look a bit confusing. How come Product 1 is able to achieve higher throughput than Product 2 (104913 reqs/s vs 46816 reqs/s), when the mean response time of Get requests is higher (530.13 us vs 344.5 us)? To understand this, we need to examine the results of Put operations at first.
BasicOperations.Put
| Configuration stress-test | requests | errors | mean | std.dev | net operation throughput |
|---|---|---|---|---|---|
| Product 1 / Cluster[default=4] | 1572984 | 0 | 906.56 us | 913.04 us | 26212 reqs/s |
| Product 2 / Cluster[default=4] | 707001 | 0 | 5.4 ms | 50.92 ms | 11657 reqs/s |
Product 1 was able to achieve higher throughput when performing Put operations (26212 reqs/s vs 11657 reqs/s). Put operations were also considerably slower than Gets for both products (Product 1 - Put: 906.56 us, Get: 530.13 us, Product 2 - Put: 5.4 ms, Get: 344.5 us). Important thing to notice here is that 4:1 Get:Put ratio is reflected in operation throughput (Product 1 - Put: 104913 reqs/s, Get: 26212 reqs/s, Product 2 - Put: 46816 reqs/s, Get: 11657 reqs/s). To proceed further, let's have a look at how the results are calculated.
Throughput(operation) (ops/sec) = num_requests / test_duration (s)
e.g. Product 1 - Throughput(Put)
26212 reqs/s = 1572984 / 60
Response time mean (RTM)
Here we simply record how long it took the method invocation performing a request to return.
It's obvious that RTM & throughput calculation are not related to each other. In previous versions we provided theoretical throughput, which was calculated as 1 / RTM, however this doesn't reflect how many operations per second the product was actually able to perform, therefore we decided to drop it from the summary.
With this knowledge let's get back to the Get results. The only way how Product 1 could achieve higher Get throughput with higher response time mean is with the help of fast Puts. Indeed, in this test Product 1 performed Puts 6 times faster (906.56 us vs 5.4 ms). As the operations (Get & Put) are performed one after the other, each time Product 2 spent considerable amount of time waiting for Put operation to return, Product1 was able to perform multiple operations meanwhile. This is reflected in higher request count (Product 1 - Put: 1572984, Get: 6295856, Product 2 - Put: 707001, Get: 2839287). As the throughput is calculated based only on number of requests the product was able to perform (not RTM), this can lead to misinterpretation of the results.
Alternatives
- Calculate total throughput as a sum of partial results (Get/Put) to avoid confusion.
- If you're in a need to calculate the performance of reads and writes separately, run a test exclusively with reads or writes. This can be achieved by tweaking get-ratio and put-ratio attributes of basic-operations-test stage (e.g. get-ratio="1" put-ratio="0" for read only test).
TODO
- Remove partial throughput charts from the report and provide "total throughput" chart only.


What does it mean if I get an error:
-
Could not connect to the multiaddr: Machines on the internet cannot talk to your machine.
Fix your firewall, add port forwarding, or use a relay.
-
Could not find address in the dht: Your machine is either not connected to the IPFS Public DHT
(even as a client), or is not advertising the address that you are testing with. As a result no one will be
able to contact you on that address if they only learn about your peerID, as is the case for content
advertised in the IPFS Public DHT
-
Multihash not advertised in the dht: Your machine has not advertised that it has the given content in the
IPFS Public DHT. This means that other machines will have to discover that you have the content in some other
way (e.g. pre-connecting to you optimistically, pre-connecting to you since related content is already
advertised by you, some rendezvous service, being on the same LAN, etc.).
-
Peer has not responded that it has the CID: Your node does not think it has the data you think it does,
or it took too long to respond. Until this is resolved other machines will be unable to download that
content from you.

Mindset & Setting: I had a good breakfast on the day of this event. I was in grad school and was experiencing no outside emotional strains. I was not depressed or suicidal. Consumption occurred at my house.
The lure of pushing the envelope is for some is a seductive ideal. I realize the human body is not indestructable, but if Keith Richards is still alive it can sustain signigicant damage without being fatal. I would like to preface this experience by saying it is not safe to mix uppers and downers. The combination confuses the body and can be fatal. But if you are reading this you probably already know that.
5:00 pm I broke open two 60mg capsules of Darvon and dumped the contents onto a piece of paper. I then took two 10mg Valium and crushed them and mixed them into the Darvon. I call this mixture a Partly Cloudy. I poured the mixture on my tongue and chased it with a Coke. I recommend something sweet, because the Darvon stings my tongue and the Valium is becomes bitter to the taste when powdered.
5:15pm The Partly Cloudy had taken effect. I felt warm and relaxed with a subtle euphoria.
5:20pm I took three 10mg Ritalin (immediate release). I crushed two and snorted them. I ate the other.
5:30pm The relaxing qualude like feeling of the Darvon/Valium mixture was accentuated perfectly by the Ritalin. I was able to enjoy the opiate like high without the slow mental reaction and thoughts processes related their use.
5:45pm I experienced a physical high like nothing I can describe. It was the best I have ever felt in my life, but not the highest I have ever been.
7:10pm I began feeling edgy from the Ritalin. Taking one if you are snorting them usually helps with this feeling, but you really only have two choices: ride it out, or add some more downers to the mix. I crushed up a 30mg Morphine tablet and snorted it-problem solved. An excellent buzz and the best of both worlds.

This module identifies the topological separate objects within an isosurface (ie segments) and orders them by size, the user can select which objects to display. This allows visualization of objects by removing obscuring artifacts.
Input Ports
in Mesh Mesh from an isosurface. Parameters
#Objects UIslider IsoObjsReduce: The number of the largest objects to return.
IsoObjsReduce2: The number of the largest objects to listObjects to Display UImultiList IsoObjsReduce2: A list of objects (largest first) that can be displayed. Output Ports
out Mesh Mesh containing the requested objects. obj DataObject Renderable object
Isosurfacing is probably the most the most used form of 3D visualization unfortunately like most other methods it can suffer from noisy data. Preprocessing may not always be possible or wanted but noise can double the number of triangles in a isosurface and hence obscure the structure to be visualised as well as hit performance. Theses macros find the individual objects in a isosurface and sort these in order of size. IsoObjsReduce will return the specified number of the largest objects and IsoObjsReduce2 will allow you to choose which objects of returned from a list.
For more details on the modules contained in these macros see the documentation.
in
A mesh from an isosurface though of course it can be any mesh containing a Tri cell_set.
#Objects
IsoObjsReduce: Returns the this many of the largest objects.The output mesh will be updated each time you select a different number objects.
IsoObjsReduce2: List this many of the largest objects in the UImultiList.
Objects to Display
IsoObjsReduce2: A list of objects (largest first) that can be displayed. The output mesh will be updated each time you select different objects.
out
The mesh containing the objects selected from the isosurface and a single Tri cell_set.
obj
The directly renderable output mesh.

You define the animation effects by setting the control's effects() property. This should be a dictionary of CSS properties that can be animated with $.animate(). The position and size of the content can be animated without moving adjacent elements in the document flow; while the mouse is over the content, the control leaves a placeholder element of the content's original size to hold the shape of the surrounding elements.
To animate color properties (as shown in the demo), include a plugin such as Color Animation.
This control was discussed in a user interface blog post.


Internet connection is just point to point connection of two
points on the Internet, full duplex connection data flows in both the directions
after the connection has been established. It is reliable.
Socket, it's just an end, end to the point to point connection, so for
an internet connection we need two sockets, one on the client side and the other
on the server,
Breaking down the sockets in two parts, they are IP address and port
number for example client socket can be <IP_ADDRESS>:9898, so on the left of
colon is the IP address of the client and on the right side is a port number.
So why does client have random port number but the server side has
80?
Because the server side has to be more reliable and available for all
the time.
Four basic funtions :
Core UI gets to the OS to use the draw function. Handle z axis, over and under DOM Tree constantly changes and needs to be re-parsed dynamically.
(Hyper Text Transfer Protocol)
Cookies are something which is a function of state and that is a part
of client side (browser) and session is related to the web server, web
client(browser): server ∷ we: Starbucks ∷ cookies: session.
Cookies are always client side and can actually be seen from the
browser for all the diff website.
Every single http request sent by our browser carry a cookie with it
so that the server can do something smart with it. Http is originally a
stateless protocol but sessions and cookies make it state full.
Cookies are always client side but session is mostly server side but
sometimes sessions are also stored on the client side, that makes it real fast
but there is lack OS space.
Asset can be anything like hardware, software or data. The perceived
value of an asset depends upon the ease with which the asset can be replaced.
One of the major goal of information security is to reduce the
security risks but along with it also to protect the valuable assets.
To study methods of assets protection, we use a
vulnerability-threat-control framework.
Vulnerability is a weakness in the system, and can be exploited to
cause harm or loss.
Threat, a set of circumstances that has the potential to cause harm or
loss. Control, an action, device, or procedure that eliminates or reduce a
vulnerability. Threats are blocked by controlling vulnerability!
CIA= the security triad, so the threats can be thought to interfering
with CIA of an information system.
Confidentiality - the ability of a system to ensure that assets are
viewable only by authorized parties.
Integrity - the ability of a system to ensure that assets are modified
only by the authorized parties.
Availability - the ability of a system to ensure that assets are only
usable and assessable by authorized parties.
Aside from CIA other system properties include :
Authentication - the ability of a system to confirm the identity of a
sender.
Nonrepudiation - property of a system in which the sender can't
convincingly deny having sent a message.
Auditability - ability of a system to trace all actions related to a
given asset.
harm to a system can be caused by 4 different ways-
Each of the above acts are harmful acts and can affect the system's ability to ensure CIA.
For an attack to be successful attackers need MOM!
If any one of three is eliminated, attack will not be successful
Six approaches to defend our system-

--- layout: post title: "Updating my site with org-mode" permalink: /:title/ tags: [blog, org-mode] ---
This is of a technical interest on how I actually produce my blog. I have always written by blog pages in emacs and historically have authored in Markdown syntax and the Beautiful Jekyll theme on GitHub. I now author my pages in org mode and use org-publish to render them to the Jekyll repository. Next I ensure that the blog posts are in the _posts/ folder and commit those changes to the git image of my site. Finally, I upload and push my local site to GitHub.
All my pages need a special header which looks like this.
#+OPTIONS: toc:nil num:nil #+BEGIN_EXPORT html --- layout: post title: "Updating my site with org-mode" permalink: /:title/ tags: [blog, org-mode] --- #+END_EXPORT
I then use org-mode to write and format my text.
My org-publish of blog renders all the pages into _drafs/ folder where the jekyll image is located. I move the post from the _drafts/ folder into the _posts/ folder which makes the post live. Adding the post to the jekyll image by a git add followed by a git commit. A git push origin master causes the changed website live.

Create a CSS file, and style your images:
img {
width: 32%
}
Add a media query section:
Give it the parameter of max-width: 1080px. That means from 0 to the max of 1080px window width, this rule will apply. Anything over 1080 will fall back to the rules before the media query.
Let’s have the views less that 1080px wide show a full-width photo.
See the dimensions of your window by pressing command+option+i. Keep an eye on the upper right of your window as you change its width and a little dimensions box should appear.
css @media (max-width: 1080px) { img { width: 100%; } } @media (min-width: 1081px) { body { background-color: red; } }
Save and change your html page window width again to see your red background at 1081px and wider.
Add another media query after your red one, but make the background green starting at min-width: 1200px.
Next, highlight that 1200 media query, hold command+ctrl, and use the up arrow to move it before the 1081 rule. Refresh and try your webpage now.
@media (min-width: 1200px) {
body {
background-color: green;
}
}
@media (min-width: 1081px) {
body {
background-color: red;
}
}
Click the ‘index.css:’ link by your style to see where the rule being followed is in your code. This should take you to to Sources tab, and show you which line it’s on.
css @media only screen and () { }
Form small groups and discuss:
body {color: red}
on line 5, and body {color: green}
on line 6, what color would the text be when the window is 700px wide?{color: red} on line 5
, and the media query @media only screen and (min-width: 600px) {color: blue}
on line 6, what color would the text be when the window is 700px wide? What color would it be at 500px wide? 600px wide?


We're so excited to share our love of animals with our neighbors, and we hope you come visit soon. Whether you stop by once while you're passing through town or come multiple times a week, you'll find the Ithaca Zoo is ready to welcome you with open arms.
Advisory: due to upcoming hot weather, we advise all guests to make sure they bring sunscreen for protection from ultraviolet rays and a water bottle to help stay hydrated. We have water fountains all over the zoo where you can fill up. Just look for the signs that say "Watering Hole."
Our next event is the Red Panda Meet and Greet, where you have a chance to meet our favorite little bundles of joy, Red and Fluffy. This will take place next Saturday from 1:00-4:30 PM. There will be a line, so come early.
The Red Panda Meet and Greet was the most fun my kids had all summer! - John Smith Sr.
Meeting Apple and Fluffy was cool. - John Smith Jr.
