It seems you're using Windows XP SP2 COM API, which is known to have issues on Windows Vista/7 and newer versions.It's recommended that you use the newer API:(I have not tested this)Type netFwPolicy2Type = Type.GetTypeFromProgID("HNetCfg.FwPolicy2");

I got an answer for the question. I'll post it here in case anyone else has trouble.
Apparently, overhead is a more general term in Computer Science that I'd never heard before, referring to extraneous resources - in this case, bits.
When referring to cache overhead, the question was referring to bits that are necessary for the cache, but that do not include the data itself.
In this particular case, the cache included the validity bid, and the tag. In order to calculate the overhead as a percentage, I had to take the sum of all validity bits and tag bits and divide them by the total cache size.
|
I've been given a problem by my computer architecture professor but it is using some terminology that I cannot find in our textbook.
Basically, I'm given a cache with the following parameters:
-4KB address space
-Byte-addressable memory
-Direct-Mapped
-2 blocks in cache
-4-word blocks
I have no problem drawing out this cache and modeling what would happen with various inputs. However there is one question I'm being asked:
"The cache stores overhead information. What percentage of the total
cache storage is this overhead?"
I have no idea what this means. I've been searching "cache overhead" on Google and StackOverflow and I haven't been able to find anything that places those two words together in a helpful context for me. I don't see it in my textbook either.
Any insight would be greatly appreciated.
Thank You!

You could forward environment variables etc from the parent image by writing to a file and the copy it into the next image. Then in your entrypoint somehow read it and export variables etc. But i would say it's a bit exotic design.
But in your case there seems to be quite a bit of dependencies on variables and packages so maybe it just easier to not user multi-stage at all?

I have an application packages as .bin and it runs on rhel7-init base image. The following is the Dockerfile with the parent image and child image.
FROM registry.access.redhat.com/rhel7-init:7.3 as base
COPY yum.repos.d/ /etc/yum.repos.d/
RUN yum -y install sudo systemd
RUN yum install https://download.postgresql.org/pub/repos/yum/9.4/redhat/rhel-7-x86_64/pgdg-redhat93-9.4-3.noarch.rpm -y && \
yum install -y postgresql94
RUN export key=value && \
installer.bin &> /root/install.log
FROM registry.access.redhat.com/rhel7-init:7.3
COPY --from=base /opt/app/ /opt/app
COPY start_app /root/
RUN chmod +x /root/start_app
ENTRYPOINT [ "/root/start_app" ]
It has a start script given as ENTRYPOINT which configures a few things at runtime as it brings up the container. I copied the installed directory location to the new image from the parent image.
Now when I start my container, it shows dependencies on which sudo packages which were installed in the parent image.
How do I carry forward the installed packages of my parent base image to my new base image without adding too much size?
Can I also carry forward any env variables present in the installer used in the parent base image?

On MAC, if above-mentioned tricks don't work, do the following:
Open Keychain Access
Search for CodeCommit. You should find this:
Select 'git-codecommit....' and press delete
Confirm the delete.
Now try again. It should work. You may have to do it again next time as well when you face the error 403.
One of the possible reason for this issue is the keychain password different than login password on your MAC.

You might consider:
making sure your submodule B, in repository A, follows a branch (main, for instance)
using a multi-project pipeline
You can set up GitLab CI/CD across multiple projects, so that a pipeline in one project can trigger a pipeline in another project. You can visualize the entire pipeline in one place, including all cross-project inter-dependencies.
Your first pipeline would be triggered only on pushes.
And it includes a trigger to your project A, which would then execute a git submodule update --remote, in order to update the submodule B.
|
I have a project A and I have added a submodule to another project B.
I see that the submodule used in A is referring to a particular commit, and I would like this to be updated every time a new commit appears in B.
Is it possible to trigger an automatic pull/push of the submodule in A when B is updated?
Or this procedure has to be done always by hand?

Although it is not possible to set an alias for the exec mode when using a container it is however possible to do it for run mode using the script below:
%runscript
alias python3='python3.6'
eval ${@}
The difference between exec and run is that exec runs the command you write directly but run passes whatever you write to the script you've written in %runscript.

I have been trying to set some aliases in my container but I haven't been able to do it successfully. While building the container I put alias python3=python3.6 in %post and things work fine; the alias is correctly declared and is used throughout the container building process.
However, after the container is built and I execute it, using singularity exec, the alias declaration in %environment or%runscript does not work. I also tried putting the alias declaration command in a bash script in the container and run the bash script but it still does not work. Basically, I think I'm looking like ENTRYPOINT in Docker for Singularity. Does anyone know what I'm doing wrong and how I can set aliases within a container?
I'm using Singularity 2.6.

As told by mario, the problem is that s3 resolution is higher than those other models, so images are bigger in dimensions and, therefore, also in memory consumption.
Although it is worth to say that the S3 seems to have a little maximum heap size givin its resolution, since I have also had out of memory problems with it but not with other devices with same resolution that has a heap limit higher.

Your analysis is indeed correct, but I guess your professor is looking for an explanation like this:Suppose the single cycle processor also has the stages that you have mentioned, namely IF, ID, EX, MA and WB and that the instruction spends roughly the same time in each stage as compared to the pipelined processor version. Now you can draw a pipeline diagram for this single cycle processor, and see that it would take 50 cycles on a single cycle processor (which can work on 1 instruction at a time) compared to the 19 cycles on a pipelined processor.Again, I prefer the way you have analyzed it (as the single cycle processor wouldn't really have each of those stages in a different clock cycle, it would just have a very long clock cycle to cover all the stages). Also, you've not mentioned whether this is a stalling-only MIPS pipeline (for which your answer is correct) or if this is a bypassed-MIPS pipeline. If this is the latter, you can shave off a few more cycles and get it down to 15 cycles. | I have to compare the speed of execution of the following code (see picture) using DLX-pipeline and single-cycle processor.Given:an instruction in the single-cycle model takes 800 psa stage in the pipeline model takes 200 ps (based on MA)My approach was as follows.CPU time = CPI * CC * ICSingle-cycle:CPU time = 1 * 800 ps * 10 instr. = 8000 ps.Pipeline:CPI = 21 cycles / 10 instr. = 2.1 cycles per instructionCPU time = 2.1 * 200 ps * 10 = 4200 ps.CPU time single-cycle / CPU time pipeline = 8000/4200 = 1.9, sothe pipeline code runs 1.9 faster.But I was said, I have to work with clock cycles and not with the time -- "It doesn't matter how much time a CC takes".I don't see how to make a comparison otherwise.

You're essentially correct, though there are a few ways that it was typically done to make it look less awkward:
Foo* someFoo = [[Foo alloc] init];
self.foo = someFoo;
[someFoo release];
Or more succinctly:
self.foo = [[[Foo alloc] init] autorelease];
|
I am using ARC but reading the MRR part of Objective-C, and it seems like if a property of ViewController is (for non-ARC):
@property (retain, nonatomic) Foo *foo;
then the viewDidLoad of ViewController will need to do a release right after alloc and init:
- (void)viewDidLoad
{
[super viewDidLoad];
self.foo = [[Foo alloc] init];
[self.foo release];
}
Otherwise, the retain will increment the reference count of the Foo object once when it is assigned to _foo (the instance variable), and @property (retain, nonatomic) Foo *foo;
0 also increment the reference count once, so it is claiming ownership twice, and therefore, there needs to be a @property (retain, nonatomic) Foo *foo;
1 right after the @property (retain, nonatomic) Foo *foo;
2 and @property (retain, nonatomic) Foo *foo;
3?
I just feel it is a bit weird looking because an @property (retain, nonatomic) Foo *foo;
4 is immediately followed by a @property (retain, nonatomic) Foo *foo;
5 this way.
(If we do is a @property (retain, nonatomic) Foo *foo;
6, then one ownership is claimed by the autorelease pool, and one claimed by ViewController, and at the end of the event loop, the autorelease pool drains, and unclaim one ownership, and therefore the Foo object is correctly owned once only. (but if Foo doesn't have such methods and only have @property (retain, nonatomic) Foo *foo;
7 and @property (retain, nonatomic) Foo *foo;
8, then the immediate @property (retain, nonatomic) Foo *foo;
9 is needed.))
| In Objective-C MRR, if foo is a retain property, then self.foo = [[Foo alloc] init] will need to be released immediately? |
Use resolver in nginx config
The nginx resolver directive is required.
Nginx is a multiplexing server (many connections in one OS process), so each call of system resolver will stop processing all connections till the resolver answer is received. That's why Nginx implemented its own internal non-blocking resolver.
If your config file has static DNS names (not generated), and you do not care about track IP changes without nginx reload, you don't need nginx's resolver. In this case all DNS names will be resolved on startup.
Nginx's resolver
Nginx nginx0 directive should be used, if you want to resolve domain name in runtime without nginx1 reload.
E.g.:
nginx2
nginx3
Use the same network (not your case, but still worth noting)
Containers you are trying to link may not be on the same network.
You may want to put them all on the same network.
In your case subnets are the same, it's ok:
nginx4
nginx5

Git cares only about the executable bit. The rest is left to the system. Unix systems have a per-process umask value, set and maintained by the umask command, that says which permissions not to grant. 0022 and 0066 and 0077 are common settings for that. My Arch linux default is 0022, don't grant write privilege to anyone but me. It looks like your linux distro defaults to 0002, don't grant write privilege to the general public, but allow it for you and your group.
So put umask 0022 in your shell startup. If you want it system-wide, look in /etc/profile, the Arch one runs any hooks in /etc/profile.d so you could add an override there.

I had the same problem.
My approach was to sanitize the repo by BFG and then push the clean repo to the new server.
Here an example:
git clone --mirror git://some-server.com/some-dirty-repo.git
java -jar bfg.jar --delete-files /some-dirty-path/some-dirty-files-pattern
cd some-dirty-repo.git
git reflog expire --expire=now --all

My company has a Git repo that supports LFS.
The LFS was set up before I joined.
I believe person set it up didn't tell other people. So over time, there are missing LFS objects here and there.
That brings it to today.
I was tasked with moving the current repo to a new repo.
However, when I try to fetch and push the LFS objects, there are missing LFS objects. Nobody knows where those are anymore.
Now I don't care about LFS in the new repo.
Is there anyway I can migrate my current repo to the new repo without LFS?
I want the actual files to be moved, not the LFS pointers.

This looks like a git submodule to me:✓ Folderis a double grayed out folder icon on GitHub✓ When repo is cloned, files from the folder are not copied locally✓ Can commit files in the folderLooks like you may have accidentally created agit submodule. The way to fix this would be to look for a.gitmodulesfile in the root of your local repository.Delete the.gitmodulesfile and it should "free up" all of the files in that folder so you can commit them normally into your repository. Commit, push, and it should be fixed!In response to your comment (which makes it clear that you are using submodules on purpose), to clone a repository including all submodules, usegit clone --recursiveinstead of the normalgit clone. This will cause all the files (and indexes) from your submodules to be downloaded as well, so you no longer get empty folders. | So I have a blog up and running fine using Jekyll and GitHub. The weird thing is that when I view my repo via the GitHub website and navigate to the folder containing my blog, it is greyed out (the icon is a double grayed out folder one on top of the other).Also when I clone my repo the folder doesn't copy any files locally. Everything else copies just fine except the folder containing my blog.Is this because it is being hosted from that folder? I think this is not the case and I did something wrong. The strange thing is I can commit to the folder and the blog works perfectly.For obvious reasons I want to be able to make posts via browser sometimes and when I clone as a back up I want my blog to be downloaded as well.Can anyone help? | Jekyll GitHub Blog Folder Not Accessible |
As for my experience, You should use multiple levels of cache. Implement both of Your solutions (provided that it's not the only code that uses "SELECT title, body FROM posts WHERE id=%%". If it is use only the first one).
In the second version of code, You memcache.get(query.hash()), but memcache.put("feed_%s" % id, query_result). This might not work as You want it to (unless You have an unusual version of hash() ;) ).
I would avoid query.hash(). It's better to use something like posts-title-body-%id. Try deleting a video when it's stored in cache as query.hash(). It can hang there for months as a zombie-video.
By the way:
id = GET_PARMS['id']
query = query("SELECT title, body FROM posts WHERE id=%%", id)
You take something from GET and put it right into the sql query? That's bad (will result in SQL injection attacks).
|
Something I'm curious about.. What would be "most efficient" to cache the generation of, say, an RSS feed? Or an API response (like the response to /api/films/info/a12345).
For example, should I cache the entire feed, and try and return that, as psuedo code:
id = GET_PARAMS['id']
cached = memcache.get("feed_%s" % id)
if cached is not None:
return cached
else:
feed = generate_feed(id)
memcache.put("feed_%s" % id, feed)
return feed
Or cache the queries result, and generate the document each time?
id = sanitise(GET_PARMS['id'])
query = query("SELECT title, body FROM posts WHERE id=%%", id)
cached_query_result = memcache.get(query.hash())
if cached_query_result:
feed = generate_feed(cached_query_result)
return feed
else:
query_result = query.execute()
memcache.put("feed_%s" % id, query_result)
feed = generate_feed(query_result)
(Or, some other way I'm missing?)

You can achieve this by usingSet-ItResult, which is a Pester cmdlet that allows you to force a specific result. For example:Describe 'tests' {
context 'list with content' {
BeforeAll {
$List = @('Harry', 'Hanne', 'Hans')
$newlist = @()
foreach ($name in $List) {
if (($name -eq "Jens")) {

}

if (-not $newlist) {
Set-ItResult -Skipped
}
else {
$newlist | ForEach-Object { $_.length | Should -BeIn (1..10) -Because "The maximum name length is 10 characters" }
}
}
}
}Note that there was an error in your example ($newlistwasn't being updated with name, you were doing the reverse) which I've corrected above, but your test doesn't actually fail for me in this example (before adding theSet-ItResultlogic). I think this is because by usingForEach-Objectwith an empty array as an input theShouldnever gets executed when its empty, so with this approach your test would just pass because it never evaluates anything. | I would like to be able to skip tests if list is empty.a very simplified example:No name is -eq to "jens", therefore the $newlist would be empty, and of course the test will fail, but how do i prevent it from going though this test if the list is empty?context {

The only way to update a pull request is to push to the branch that's been PRed - so even the original repo's owner can't amend the PR, by default. It does make sense - for traceability's sake, at least.
So if you want to finish that work, the best thing you can do is to fork the original repo, clone it on your machine, add the PR's repo as a remote, checkout the PR'ed branch, commit on top of that, push those changes to your own fork, and make a new PR stating in the comments that it continues and fixes the other PR, so the original PR would get closed when yours' is merged.
In this case, something like:
$ # Go to https://github.com/cheeriojs/cheerio/ and fork it
$ git clone https://github.com/Delgan/cheerio/ && cd cheerio # assuming that's your GH username :)
$ git remote add pr-base https://github.com/digihaven/cheerio/
$ git fetch pr-base
$ git checkout pr-base/master -b 641-appendTo_prependTo
$ # work work work
$ git add #...
$ git commit -m 'Fixed all the things! See #641, fixes #726'
$ git push origin 641-appendTo_prependTo
$ # Go to your repo and make the PR
$ # ...
$ # SUCESS! (??!)

You can set the fragment_cache_store in your environment.rbActionController::Base.cache_store = ActiveSupport::Cache::MemCacheStore.new()http://api.rubyonrails.org/classes/ActionController/Caching.html#M000628 | Is there any way of using Memcached for fragment caching in Rails? | Fragment Caching with Memcached |
There are several problems with your code:
you store all characters into the first byte of allocated memory
you read characters into a char variable, you cannot correctly test for EOF.
you will run an infinite loop, allocating all available memory and finally crash if standard input does not contain a '\n', such as redirecting from an empty file.
less important, you reallocate the buffer for each byte read, inefficient but can be optimized later.
Here is a corrected version:
#include <stdio.h>
#include <stdlib.h>
int main() {
char *string;
int c;
int len = 0;
string = malloc(1);
if (string == NULL) {
printf("Error.\n");
return -1;
}
printf("Enter a string:");
while ((c = getchar()) != EOF && c != '\n') {
string[len++] = c;
string = realloc(string, len + 1);
if (string == NULL) {
printf("cannot allocate %d bytes\n", len + 1);
return -1;
}
}
string[len] = '\0';
printf("Input string: %s\n", string);
free(string);
return 0;
}
Regarding your question about the difference with the linked code, it uses the same method, has one less bug but also one more bug:
it stores the character in the appropriate offset in str.
it runs an infinite loop if the input file does not contain a '\n', same as yours.
it invokes undefined behavior because c is not initialized for first test.
|
I'm learning C programming and I have to implement a program that read an input string of of unknown size.
I wrote this code:
int main() {
char *string;
char c;
int size = 1;
string = (char*)malloc(sizeof(char));
if (string == NULL) {
printf("Error.\n");
return -1;
}
printf("Enter a string:");
while ((c = getchar()) != '\n') {
*string = c;
string = (char*)realloc(string, sizeof(char) * (size + 1));
size++;
}
string[size - 1] = '\0';
printf("Input string: %s\n", string);
free(string);
return 0;
}
But the last printf doesn't show the whole string but only the last char.
So if I enter hello, world the last printf prints d.
After a little research I tried this code and it works! But I don't get the difference with mine.
I hope I made myself clear, thank you for your attention.

I suggest you to use Azure IaaS VM backup to backup and restore your VMs. Azure backups can be created through the Azure portal. This method provides a browser-based user interface to create and configure Azure backups and all related resources. You can protect your data by taking backups at regular intervals. Azure Backup creates recovery points that can be stored in geo-redundant recovery vaults. This article details how to back up a virtual machine (VM) with the Azure portal.

Dedicated GPU memory is basically the VRAM on-board the GPU
System GPU memory is memory that the graphics card driver is using the GART (Graphics Address Remapping Table) to store resources in system memory... AGP and PCI Express both provide regions of memory set aside for this purpose (sometimes referred to as aperture segments).
Committed GPU memory refers to the amount of memory mapped into a display device's address space by the display driver, it is a difficult concept to explain but this number typically does not represent anything worthwhile to anyone but driver developers.
I suggest you look into the following documentation on MSDN as well as this overview of GPU address space segementation, while they are somewhat technical they give a general overview of what is going on.

As @Ajan comments, Java 8 doesn't have a "permgen" heap space anymore, and that option will be ignored.
But this isn't a permgen problem at all. In fact, it is most likely a sign that the main Java heap is full. This exception gets thrown if the JVM detects that the GC is taking too large a proportion of the total CPU time over the last few GC cycles. This generally happens because the heap is getting close to full, and the GC is being run more and more frequently.
So, the "quick fix" for the problem would be to increase the main heap size using an -Xmx... option. However, if the real problem is that you have a memory leak, then that is only putting off the inevitable. Unless you already understand why your application is using a lot of memory, you should probably start looking for memory leaks.

There're two theoretically possible ways to solve your issue:Nginx with ngx_stream_ssl_preread moduleHAproxy (for balancing) -> proxy_protocol -> Nginx (with ssl certs) | Host A has https serviceserviceAand provides two IP for high availability。e.g. Bose [ip1:443] and [ip2:443] are routed to theserviceA.Host B (do not has ssl_certificate and ssl_certificate_key) use Nginx proxy module to proxies the requests towards the actualserviceA.
How to simply forward 443 port traffic toserviceAwithout ssl verification?
Here is my config:http {
upstream backend {
server [ip1]:443;
server [ip2]:443;
}
server {
listen 443;
listen [::]:443;
location / {
proxy_pass https://backend;
}
}
} | How to disable ssl certificate and only used to forward traffic on port 443 in Nginx? |

Did you do apt-get update before that?
And then
apt-get -y install python-pip

Your error message points to a bug in the openssl version you use. Seehttps://bugzilla.redhat.com/show_bug.cgi?id=1022468. In short: the client advertises capabilities it does not have and if the server picks such capability you get this error message. Needs to be fixed by upgrading your local openssl installation. A workaround on the server side should be possible too, if you have control over the server. | I have the following code to use:def createCon(host,auth):
con = httplib.HTTPSConnection(host)

You can create a new service and leverage theinterpreterSettingNamelabel of the spark master pod. When zeppelin creates a master spark pod it adds this label and its value isspark.

From Actions, Resources, and Condition Keys for Amazon S3 - AWS Identity and Access Management:
ListBucketVersions: Use the versions subresource to list metadata about all of the versions of objects in a bucket.
I tested this as follows:
Created an IAM User
Assigned the policy below
Ran the command: aws s3api list-object-versions --bucket my-bucket
It worked successfully.
The policy was:
{
"Version": "2012-10-17",
"Statement": [
{
"Effect": "Allow",
"Action": "s3:ListBucketVersions",
"Resource": "*"
}
]
}
So, while the naming seems a bit strange (List Object Versions vs List Bucket Versions), it is the correct permission to use.
|
I currently have a lambda that uses the node sdk call listObjectVersions to list all the versions of a specific file. However, I can't figure out what permission in my policy will grant the lambda permission to make this call. I've searched the AWS documentation and I can not find any information.
Here are the current permissions in my policy:
- PolicyName: S3Policy
PolicyDocument:
Version: 2012-10-17
Statement:
- Effect: Allow
Action:
- s3:PutObject
- s3:PutObjectAcl
- s3:GetObject
- s3:GetObjectVersion
- s3:ListObjectVersions
- s3:DeleteObject
- s3:ListBucket
When I execute the lambda I get an Access Denied when making the call. I've changed my policy to allow the action s3:* and the lambda works. However, I do not want to grant full access to s3.
What Action do I need to add to allow?

sizeof(Rz3DContourNode) == 6*4 = 24 bytes ... not 12!
The stride is the # of bytes between the start of each vertex, not the padding. Although 0 is a special value that indicates tightly packed data.
So, if you're using 3 floats as vertex data, there's no difference between a stride of 0 and 12 (because 3 floats are 12 bytes). In your case, your struct is 24 bytes, so you should put that.
This convention (stride = step size, not padding) allows the simple use of sizeof, so you ended up doing the the right thing intuitively. That's good API design for you. :)
See glVertexPointer docs:
stride
Specifies the byte offset between consecutive vertices. If stride
is 0, the vertices are understood to be tightly packed in the array.
The initial value is 0.
|
I have following struct to store my vertex data.
struct Rz3DContourNode {
float x; //pos x
float y; //pos y
float z; //pos z
float nx; //normal x
float ny; //normal y
float nz; //normal z
};
I store list of vertices in STL vector as follows :
std::vector < Rz3DContourNode > nodes;
When I try to use this as as vertex-array in OPEGL ,in does not render incorrectly.
glVertexPointer(3, GL_FLOAT, 12, &nodes[0]);
glDrawArrays(GL_POINTS,0,nodes.size());
So, I tried to confirm the values using pointer arithmetic (assuming thats the way OPENGL handle data) as follows:
float *ptr=(float*) &nodes[0];
for(int i=0;i<nodes.size();i++)
{
Rz3DContourNode confirmNode=nodes[i];
float x=*ptr;
ptr++;
float y=*ptr;
ptr++;
float z=*ptr;
ptr++;
//Confirm values !!! Do not equal ??
qDebug("x=%4.2f y=%4.2f z=%4.2f | nx=%4.2f ny=%4.2f nz=%4.2f
",confirmNode.x,confirmNode.y,confirmNode.z,x,y,z);
//Skip normal positions
ptr++;
ptr++;
ptr++;
}
The values does not equal if I directly access values from the struct.
Does this means struct does not save the values contiguously ?
[EDIT] I Just noticed that using sizeof() instead of 12 fix the problem as follows:
glVertexPointer(3, GL_FLOAT, sizeof(Rz3DContourNode), &nodes[0]);
But still I am confused why my hack didnt traverse correctly in memory?(why qDebug doesnt print identical values ?)

The code in a PR is run "as is". If there was an "environmental" issue that was fixed, rerunning the jobs would indeed solve it.
In this case, another PR was merged in order to fix the problem. You should rebase your PR on top of the fix (probably on top of the main or master branch it was merged into) in order to be able to run the PR with the fixed tests.

@Ian if you're referring to the PR completion strategy of "rebase and merge", selecting that won't necessarily rebase your branch for you before you complete the PR. (I think...) If you want the test to pass before you complete the PR, you may need to rebase the branch yourself and force push it back out.

We have some pull requests people have made, which fail an automated analyze test/check (the failure was not related to any change the PR did, but I think a change in the analyze or formatting checks).
Another person has since fixed the issue with a new PR which has been merged which was causing the other PRs to fail the tests.
I was expecting if I "re-run all jobs", for the original PRs to now pass, but it's still failing with the same error (that the new PR has fixed). So I'm guessing it's still looking at the previous point before the new PR was merged.
What is the flow to get around this problem? (I could possibly just merge anyway and ignore the failed analyze test, but that doesn't feel quite right ?)

The main difference between the two is, PutItem will Replace an entire item while UpdateItem will Update it.
Eg.
I have an item like:
userId = 1
Name= ABC
Gender= Male
If I use PutItem item with
UserId = 1
Country = India
This will replace Name and Gender and now new Item is UserId and Country.
While if you want to update an item from Name = ABC to Name = 123 you have to use UpdateItem.
You can use PutItem item to update it but you need to send all the parameters instead of just the Parameter you want to update because it Replaces the item with the new attribute(Internally it Deletes the item and Adds a new item)
Hope this makes sense.
|
Based on DynamoDb documentation why would anyone use updateItem instead of putItem?
PutItem - Writes a single item to a table. If an item with the same primary key exists in the table, the operation replaces the item. For calculating provisioned throughput consumption, the item size that matters is the larger of the two.
UpdateItem - Modifies a single item in the table. DynamoDB considers the size of the item as it appears before and after the update. The provisioned throughput consumed reflects the larger of these item sizes. Even if you update just a subset of the item's attributes, UpdateItem will still consume the full amount of provisioned throughput (the larger of the "before" and "after" item sizes).

Solution
Make a .gitattributes file in your working directory and add the following line to it:
*.docx binary
Why not just set core.autocrlf=false ?
This is useful too. But configuring .docx as a binary format solves not only this problem, but also potential merge issues.
What is the origin of this problem?
From http://git-scm.com/docs/gitattributes , section "Marking files as binary". Note the italicized section.
Git usually guesses correctly whether a blob contains text or binary data by examining the beginning of the contents. However, sometimes you may want to override its decision, either because a blob contains binary data later in the file, or because the content, while technically composed of text characters, is opaque to a human reader.
.docx format is a zip folder containting xml and binary data, such as images.
Git treated your .docx as a text (and not binary) file and replaced endline characters. As Microsoft-developed format, .docx is probably using CRLF, which might have been replaced with LF in the remote repository. When you downloaded that file directly from remote, it still had LFs.
In a binary file Git never replaces endline chars, so even the files on remote repository will have proper CRLFs.
Applicable formats
This is applicable to any file format which is a zipped package with text and binary data. This includes:

I put several .docx, .txt and .pdf file into a .git repository. I can open, edit, save the local .docx file; however, when I push it to github, and download it back to my computer, Word complains that it cannot open it.
In order to store .docx file on github, is there some essential steps I should do to the git settings?

The main issue with your code is that looping through all files in the directory with ls * without some sort of filter is a dangerous thing to do.
Instead, I've used for i in $(seq 9 -1 1) to loop through files from *_9 to *_1 to move them. This ensures we only move backup files, and nothing else that may have accidentally got into the backup directory.
Additionally, relying on the sequence number to be the 18th character in the filename is also destined to break. What happens if you want more than 10 backups in the future? With this design, you can change 9 to be any number you like, even if it's more than 2 digits.
Finally, I added a check before moving site_com_${DATE}.tar in case it doesn't exist.
#!/bin/bash
DATE=`date "+%Y%m%d"`
cd "/home/user/backup/com"
if [ -f "site_com_*_10.tar" ]
then
rm "site_com_*_10.tar"
fi
# Instead of wildcarding all files in the directory
# this method picks out only the expected files so non-backup
# files are not changed. The renumbering is also made easier
# this way.
# Loop through from 9 to 1 in descending order otherwise
# the same file will be moved on each iteration
for i in $(seq 9 -1 1)
do
# Find and expand the requested file
file=$(find . -maxdepth 1 -name "site_com_*_${i}.tar")
if [ -f "$file" ]
then
echo "$file"
# Create new file name
new_str=$((i + 1))
to_rename=${file%_${i}.tar}
mv "${file}" "${to_rename}_${new_str}.tar"
fi
done
# Check for latest backup file
# and only move it if it exists.
file=site_com_${DATE}.tar
if [ -f $file ]
then
filename=${file%.tar}
mv "${file}" "${filename}_1.tar"

I was able to script the backup process, but I want to make an another script for my storage server for a basic file rotation.
What I want to make:
I want to store my files in my /home/user/backup folder. Only want to store the 10 most fresh backup files and name them like this:
site_foo_date_1.tar site_foo_date_2.tar ... site_foo_date_10.tar
site_foo_date_1.tar being the most recent backup file.
Past num10 the file will be deleted.
My incoming files from the other server are simply named like this: site_foo_date.tar
How can I do this?
I tried:
DATE=`date "+%Y%m%d"`
cd /home/user/backup/com
if [ -f site_com_*_10.tar ]
then
rm site_com_*_10.tar
fi
FILES=$(ls)
for file in $FILES
do
echo "$file"
if [ "$file" != "site_com_${DATE}.tar" ]
then
str_new=${file:18:1}
new_str=$((str_new + 1))
to_rename=${file::18}
mv "${file}" "$to_rename$new_str.tar"
fi
done
file=$(ls | grep site_com_${DATE}.tar)
filename=`echo "$file" | cut -d'.' -f1`
mv "${file}" "${filename}_1.tar"
| shell backup script renaming |
To see how to make this work, have a look at a working example, such as:
https://github.com/sonatype/sonatype-aether
However, this won't help if you like to release the individual pieces. In that case, you have to just copy the <scm> elements into all the poms.
This is an active topic of discussion on the maven dev list, but don't hold your breath for a solution from there; it's a big deal.

I'm trying to release a multi-module maven project that uses git as the SCM, and among the first problems I've encountered is the way in which the maven release plugin builds the release.properties scm.url. My parent POM looks something like this:
<packaging>pom</packaging>
<groupId>org.project</groupId>
<artifactId>project-parent</artifactId>
<version>1.0.0-SNAPSHOT</version>
<scm>
<connection>scm:git:git://github.com/username/project.git</connection>
<developerConnection>scm:git:[email protected]:username/project.git</developerConnection>
<url>http://github.com/username/project</url>
</scm>
<modules>
<module>api</module>
<module>spi</module>
</modules>
And the module POMs are straightforward:
<parent>
<groupId>org.project</groupId>
<artifactId>project-parent</artifactId>
<version>1.0.0-SNAPSHOT</version>
</parent>
<artifactId>api</artifactId>
<version>0.2.2</version>
My goal is to be able to release individual modules since they each have different versions and I don't want to increment all of the versions together each time I do a release.
When I change to the api directory and do a mvn release:clean release:prepare I'm met with the following output:
[INFO] Executing: cmd.exe /X /C "git push [email protected]:username/project.git/api master:master"
[INFO] ------------------------------------------------------------------------
[ERROR] BUILD FAILURE
[INFO] ------------------------------------------------------------------------
[INFO] Unable to commit files
Provider message:
The git-push command failed.
Command output:
ERROR: Repository not found.
It looks like the maven release plugin creates the scm.url by appending the module name to the developerConnection, which ends up not being a valid repository at github. I'm not sure what the right way to set this up is. It might be the case that Maven + git + releasing an individual child module simply won't work? Any input is appreciated.

No. Celery offers no way to run anything on GPU. However, nothing prevents you to use Keras, TensorFlow, or PyTorch in your Celery tasks (as a matter of fact I see many questions here about these projects and Celery).

My problem is that I have too many tasks. One task takes a few seconds so I try to increase the number of workers.

If tasks are not heavy on CPU you can increase them to few hundred. Also, keep in mind that you can change the concurrency type to thread or eventlet/gevent.

The question is - It is possible to run celery on gpu?
Currently in my project I have settings like below:
celery -A projectname worker -l error --concurrency=8 --autoscale=16,8
--max-tasks-per-child=1 --prefetch-multiplier=1 --without-gossip --without-mingle --without-heartbeat
This is django project.
One single task take around 12 s to execute (large insert to postgresql).
What I want to achive is multiply workers as many as possible.

As mentioned in this stackoverflow answer by ttfreeman
Have you tried Kaniko? It can save the cache in gcr.io and and if
you have built your Dockerfile with right steps (see
https://cloud.google.com/blog/products/gcp/7-best-practices-for-building-containers),
it should save you a lot of time. Here is the cloudbuild.yaml
example:
- name: 'gcr.io/kaniko-project/executor:latest'
args:
- --destination=gcr.io/$PROJECT_ID/image
- --cache=true
- --cache-ttl=XXh
More info: https://cloud.google.com/cloud-build/docs/kaniko-cache

I want to cache the previously stored google cloud image while creating a new build for the project.
I have followed the official documentation : https://cloud.google.com/build/docs/optimize-builds/speeding-up-builds but while building it doesn't seems to be caching the data.
The yaml file I am using is:
steps:
- name: 'gcr.io/cloud-builders/docker'
args: ['build','--cache-from', 'gcr.io/PROJECT_ID/node-app:latest', '-t', 'gcr.io/PROJECT_ID/node-app:latest', '.']
- name: 'gcr.io/cloud-builders/docker'
args: ['push', 'gcr.io/PROJECT_ID/node-app:latest']
images:
- 'gcr.io/PROJECT_ID/node-app:latest'
I also tried to first pull the docker image as:
steps
- name: 'gcr.io/cloud-builders/docker'
entrypoint: 'bash'
args: ['-c', 'docker pull gcr.io/PROJECT_ID/node-app:latest || exit 0']
- name: 'gcr.io/cloud-builders/docker'
args: ['build','--cache-from', 'gcr.io/PROJECT_ID/node-app:latest', '-t', 'gcr.io/PROJECT_ID/node-app:latest', '.']
- name: 'gcr.io/cloud-builders/docker'
args: ['push', 'gcr.io/PROJECT_ID/node-app:latest']
images:
- 'gcr.io/PROJECT_ID/node-app:latest'
I checked there is image already present and it is also pulling the image but it's not caching the image.
How can I cache the image or is there any other process to do so in google cloud?

The solution is to not use legacy unsupported versions of nginx. Starting from version 1.3.15 (pretty old one), nginx does not log the 400 errors in such cases.See changelog for information:http://nginx.org/en/CHANGES*) Change: opening and closing a connection without sending any data in
it is no longer logged to access_log with error code 400. | Amazon Elastic Load Balancer (ELB) performs periodic health checks:In addition to the health check you configure for your load balancer,
a second health check is performed by the service to protect against
potential side-effects caused by instances being terminated without
being deregistered. To perform this check, the load balancer opens a
TCP connection on the same port that the health check is configured to
use, and then closes the connection after the health check is
completed.nginx logs these events with a 400 error, which happen many times per minutes:[07/Aug/2013:18:32:27 +0000] "-" 0.000 400 0 "-" "-" "-"how can I configure nginx to not log these events? | Configure nginx to not log ELB secondary healthcheck |
yes, it may cause some conflict in your web server, for example, you have to X-Frame-Options in your response header, I suggest you to not do that. handle you're in just one level, do whatever you can with the Django and do the rest with your web server (as I know for example Feature-Policy cant be handle in Django cleanly do this with your web server, nonce hash is not easy in web server and you should do it with your Django !)
I don't know it how much true way, Django deployment checklist suggest do SSL redirection with your web server and
you can use Django-CSP to generate the nonce hash and config your CSP policy, also you can add Feature-Policy to Nginx config by :
add_header Feature-Policy "accelerometer 'none'; camera 'none'; geolocation 'none'; gyroscope 'none'; magnetometer 'none'; microphone 'none'; payment 'none'; usb 'none'";
the best practices available on OWASP Secure Headers Project and my git repo and here is link of django secure header config
|
Now which is better for adding security headers configuration
at the application level or the nginx level like
add_header X-Frame-Options "SAMEORIGIN";
add_header Strict-Transport-Security "max-age=31536000; includeSubDomains" always;
add_header X-Content-Type-Options nosniff;
add_header X-XSS-Protection "1; mode=block";
add_header 'Referrer-Policy' 'origin';
Or at django settings
SECURE_BROWSER_XSS_FILTER=True
SECURE_CONTENT_TYPE_NOSNIFF=True
SECURE_HSTS_INCLUDE_SUBDOMAINS=True
SECURE_HSTS_SECONDS=36000
SECURE_SSL_REDIRECT=True
And what if I added them on the two levels, will it make any conflict or any problems on the future?
Sure what about any framework that provide its security middleware, not django specifically
