I think you are correct in assessing that current Cloud Run for Anthos set up (unintentionally) does not let you see the origin IP address of the user.As you said, the created gateway for Istio/Knative in this case is a Cloud Network Load Balancer (TCP) and this LB doesn’t preserve the client’s IP address on a connection when the traffic is routed to Kubernetes Pods (due to how Kubernetes networking works with iptables etc). That’s why you see anx-forwarded-forheader, but it contains internal hops (e.g. 10.x.x.x).I am following up with our team on this. It seems that it was not noticed before. | We use Google Cloud Run on our K8s cluster on GCP which is powered by Knative and Anthos, however it seems the load balancer doesn't amend the x-forwarded-for (and this is not expected as it is TCP load balancer), and Istio doesn't do the same.Do you have the same issue or it is limited to our deployment?

Experiments at a previous employer showed that the standard Linux and Solaris malloc/free implementations were not particularly efficient in high-concurrency multicore environments. We realized significant performance improvements by creating a custom allocator. I think it is definitely worthwhile to do experiments with alternative allocators. If you are still working on this project, please post your findings!
Note that this was for a web service written in C. I have no experience with nginx, Hoard, or Lockless.

I am doing some experiments to find out the ceiling of my requests per second rate of haproxy and nginx on RHEL or Centos.
Part of my setup in nginx uses embedded LUA in the form of LuaJIT. My question is this:
Does anybody have any experience or advice about the usefulness of doing some testing of these apps after building with alternative heap allocators such as Hoard or Lockless.
Any thoughts gratefully received.

According to SNS architecture and design:
If subscription is APPROVED so no matter whether there is topic associated to it or not. User will be able to delete the subscription.)
If subscription is PENDING so no matter whether there is topic associated to it or not. Amazon will delete automatically the subscription after 3 days of creation.
See the FAQ for more info (scroll down to the question titled "How long will subscription requests remain pending, while waiting to be confirmed?")

It makes absolutely no sense to not be able to delete it from the console. What if I put a wrong URL? What's the big deal if I were able to remove it? After all I'm the owner of the topic. I can delete the topic itself but not a subscription to the topic ?!

I have written an AWS Lambda function in Python that filters through instances and turns them on or off depending on how they are tagged. This will show you a working function, and the set-up needed to get it working. If you have questions on anything post it in the comments.
Here is my Lambda Function as of now:
import boto3
def lambda_handler(event, context):
startStop = event['startStop']
vertical = event['vertical']
isRunning = ''
if(startStop == 'start'):
isRunning = 'stopped'
elif (startStop == 'stop'):
isRunning = 'running'
ec2 = boto3.resource('ec2')
filters = [
{
'Name': 'instance-state-name',
'Values': [isRunning]
},
{
'Name': 'tag:Vertical',
'Values': [vertical]
}
]
instances = ec2.instances.filter(Filters=filters)
runningInstances = [instance.id for instance in instances]
if len(runningInstances) > 0:
if(startStop == 'start'):
shuttingDown = ec2.instances.filter(InstanceIds=runningInstances).start()
elif (startStop == 'stop'):
shuttingDown = ec2.instances.filter(InstanceIds=runningInstances).stop()
For reference, here is my mapping template:
{
"startStop":"$input.params('startStop')",
"vertical":"$input.params('vertical')"
}
And this is how I am passing in the parameters within the URL:

The file travis-ci?per_page=100.json is not a valid filename on Windows.
You can see that there are actual files named like this in the repo, eg repos?per_page=9999.json

IIS Cache settings have no affect on service worker caching. Remember the server code and the client code are completely decoupled.
What you are setting in IIS is the Cache-Control header value. This value is used by the browser cache, not service worker cache. You are 100% in control of what gets cached and how long it is cached in the service worker cache.
|
Specifically the cache-control property:
<?xml version="1.0"?>
<configuration>
<system.webServer>
<httpProtocol>
<customHeaders>
<add name="Cache-Control" value="no-cache" />
</customHeaders>
</httpProtocol>
<staticContent>
<remove fileExtension=".json" />
<mimeMap fileExtension=".json" mimeType="application/json; charset=utf-8"/>
</staticContent>
</system.webServer>
</configuration>
I'm developing locally with a Node server and everything works fine, but on our deployment server the app runs in an IIS instance and the ServiceWorker isn't caching the requested assets. It's not throwing errors either, so I'm wondering if it's just this "no-cache" declaration getting in the way.
I'm super new to ServiceWorkers and not at all a devops guy. Not hunting for the exact solution, just trying to narrow down the diagnosis so I have a clearer idea what to ask my back-end developer.
Thank you!

I'm not sure if this helps. I ran into this same problem recently and it seems like AWS made some changes with how we define our CORS configurations. For example, if you want to allow certain Methods on your S3 bucket in the past you have to do something like this on the editor:

<AllowedMethod>HEAD</AllowedMethod>
<AllowedMethod>DELETE</AllowedMethod>
<MaxAgeSeconds>3000</MaxAgeSeconds>
<AllowedHeader>*</AllowedHeader>

Templates uses the same interpolation syntax as all other strings in Terraform.Documentation is availableSo in your case it will look like this:path = ${is_enabled ?

}
}Nowis_enabledis a boolean string which is either set totrueorfalse. Now based on if this is true or false I want to set another variable. In pseudocode it would look like this:if is_enabled == true

You cannot clone another repository using the secrets.GITHUB_TOKEN. That token is only scoped to the repository running the workflow. If you wish to clone another repository, you will need set a repository secret with a PAT that has the permissions to perform the clone.
https://docs.github.com/en/actions/security-guides/automatic-token-authentication#about-the-github_token-secret
When you enable GitHub Actions, GitHub installs a GitHub App on your repository. The GITHUB_TOKEN secret is a GitHub App installation access token. You can use the installation access token to authenticate on behalf of the GitHub App installed on your repository. The token's permissions are limited to the repository that contains your workflow. For more information, see "Permissions for the GITHUB_TOKEN."

Python code cannot be run without the required libraries but you can tell people to install the libraries. For example, you can run pip freeze > requirements.txt to add all the dependencies to a file. When people wamnt to install the dependencies, they can run pip install -r requirements.txt. Inside a repositories README.md, you can tell people the required dependencies.
In addition, dependencies aren't usually bundled because of space concerns. If you have a bash file, you need bash to run it. If you want to bundle your project to include the language and all the dependencies, you can use a program such as the ones listed in this question
|
If I have a python library I use in my GitHub project, will someone without that python package still be able to run my code after cloning my project? If not, can a python library be attached to a repo?
Also, if I have a bash file, will it still be able to run with people without bash?
Lastly, how do you attach whole languages like Python, C#, or any language inside of your repo so everyone can use your project?

I had the same issue and the comment from Ed Harper resolved my issue:
SSMS uses a comma rather than a colon to delimit between server name
and port number. Try localhost,1433. – Ed Harper Jan 23 at 12:52
The server name field in SMSS required a format of locahost,[dockerport].

I'm quite new to Linux OS's so hope this isn't a stupid question!!
Software:
Windows 10 Pro
Docker for Windows (1.13.0-beta38 (9805))
SQL Server Management Studio v17.0 RC1
Issue:
I'm trying to connect to my SQL Server Linux container using SSMS. It's not worked, so looking over the documentation it seems you need SQL Server Tools installed (bottom of page) on top of of the SQL Server Linux image.
I followed these instructions to install SQL Server Tools on Ubuntu (base image of SQL Server Linux Image)
Error:
bash: curl: command not found
Steps to reproduce error:
Pull latest microsoft/sql-server-linux image
Run according to instructions: docker run -e 'ACCEPT_EULA=Y' -e SA_PASSWORD=yourStrong(!)Password' -p 1433:1433 -d microsoft/mssql-server-linux
Attach to container using: docker exec -it <container_id> /bin/bash
Attempt to import public repository GPG keys: curl https://packages.microsoft.com/keys/microsoft.asc | sudo apt-key add -
Thing's I've tried:
I've tried running apt-get install curl but all i get is E: Unable to locate package curl
Googling - to no end
First edit - Connecting via SSMS
I've tried connecting to the container from SSMS using the following server names (I am using SQL authentication with the credentials specified during the docker run command):
localhost:1433
localhost\[container_name]
[container_ip_address]:1433
Solution (kind of)
OK so i got this working. But I'm not 100% sure what did the trick.
I used localhost as the server name (defaults to port 1433)
I also mounted a volume to the container as part of my docker-compose.yml file:
volumes:
- C:\local\volume\path:/var/opt/mssql

A gist operates like any other repository. So let's say you've cloned something like git://gist.github.com/2322786.git:
$ git clone [email protected]:2322786.git
(If you just wanted to try this without pushing, you can use git://gist.github.com/2322786.git, which will demonstrate the merge principle and works anonymously, but does not allow you to push.)
And now you want to merge in changes from git://gist.github.com/2661995.git. Add it as an additional remote:
$ git remote add changes git://gist.github.com/2661995.git
$ git fetch changes
And then merge in the changes like this:
$ git merge changes/master
And you should be all set. This should work regardless of whether the new gist was forked from yours at some previous point or is completely unrelated.
Taking Romain's comment into account, you would then issue a push:
$ git push
This would only work if your original clone URL allows writing.
|
I have a gist on GitHub that someone forked and made changes to. I like their changes.
Is there a way to merge the changes back into my original gist?

I would recommend looking through this post on caching in Rails, it's a tremendously thorough post that goes through various strategies that may provide the outcome that you're looking for in this situation.
Though he doesn't mention it in the post, adding some sort of cache busting parameter (like a cache version id) to the arguments list might provide you with a way to expire the cache in a more universal way. For example:
cache(:version => Posts.cache_version, :direction => params[:direction], :sort => params[:sort], :page => params[:page]) do
# Later on to bust the cache
Posts.cache_version = 2
The details of how you would want to implement cache_version and cache_version= could vary depending on how you're handling other data in the application. There may also be a more elegant solution than this, but it's what came to mind.

I have a page where on the where the index action shows a list of Posts, with custom sort columns, pagination, etc. Although I can cache every individual page / sort option with
cache(:direction => params[:direction], :sort => params[:sort], :page => params[:page]) do
I can't expire all of these at once using a single call to expire_action (which is a problem). I know expire_action has a regex option, but that is messy (using a regex to search for keys created with a hash), and I am using memcached which will not work.
How can I expire all the cache members of an action with a single call to expire_action? If this is not possible, are there any other caching options you could recommend?

QWizard::addPage internally calls setPage, which calls page->setParent(...) as one of the first things done.
So yes, the wizard does take ownership of the pages, and they will be subject to normal QObject lifetimes. Deleting the wizard will delete all of the pages.

When you pushedrefs/for/masterreference to remote you have created newnamespacefor references, ang gave it namefor.Long story short, it allows to create default subset of references for each user to operate on and avoid name conflicts for refs used by different groups of repository users.Users can set their own configuration inremote.remote_name.fetchandremote.remote_name.pushconfiguration values so that most common operations with branches and tags (pull,push,fetchetc.) would use their preferred namespace instead of default one defined by repository owner.Maybe it is easier to understand if you think thatgitcreates its own hardcoded namespaces when you create repository with all default configuration, one for branches (heads) and one for tags (tags) so that you do not need to prefix your branch and tag names in every operation with branches or tags | If I understand correctly,refs/for/is a special namespace that'sused in Gerrit for uploading changes.However, out of habit, instead ofgit push origin master, I've just donegit push origin HEAD:refs/for/masterona non-Gerrit repo, which apparently worked:$ git push origin HEAD:refs/for/master

My understanding is that for every distinct labelset metric is stored as a separate time series.Prometheus will not create labelsets of{endpoint="/", user_id="1"}if they aren't exposed, same as it would not create labelset{endpoint="/foo/"}.
So you second estimation of (99*1 + 1*10,000) is correct one.On the other hand, what you are doing feels more like it belongs to logs (or traces), and not metrics. Especially since number of users is usually not that stable metric, and sudden grow of that number might occur at any time. Please refer tothis answerby @brian-brazil (author of robustperception.io). | I have a Prometheus metric request_duration with a label "endpoint". A service is running, and being scraped, and is reporting metrics to prometheus for 100 different endpoints that are all being hit, e.g.{endpoint="/users/"}and 99 other endpoints.

This is the expected behaviour , because the new statefulSet will create a new set of PVs and start over.

You need to provide more information about your environment (OS, Docker installation, etc), but basically, if you start your Redis container like this:docker run --name=redis-devel --publish=6379:6379 --hostname=redis --restart=on-failure --detach redis:latestIt should expose the port no matter what.

TLS itself has no concept of the certificate being self signed or not. When you initiate a TLS connection (either by connecting to a specific port or via STARTTLS) the server and client negotiate the TLS connection.As part of the TLS negotiation it is up to the client and server to decide whether the certificate that they're presented is valid or not. If the certificate is self signed it's possible that the client (I'm assuming you're the server) may reject the certificate because it's not issued by a known CA or it might accept it.It's therefore possible to use TLS with self signed certificates (we do it) but it's also possible that a client could reject the connection because it cannot verify the certificate. If you full have control of the clients (which you do here) you can of course aid this and ensure you always accept your hosts certificate. | I'm usingSMTPtransport.

I have solved it with another way, using 2 batch files
So I give you my code:This one creates a folder in c: , than it creates a text file, it copies the name of the current user in it, than the other batch file in the same folder, and finaly runs it as local admin. If you write the password correctly(password will not appear as " * " when you write it):mkdir c:\tempfiles$
break>c:\tempfiles$\temp.txt
echo %username% >> "c:\tempfiles$\temp.txt"
copy "%~dp0\admin.bat" "c:\tempfiles$"
runas /noprofile /env /user:%computername%\<LOCAL ADMIN USER> "C:\tempfiles$\admin.bat"
pause
rmdir /s /q "c:\tempfiles$"The admin.bat, takes the user name writen in the text file (if this wasn't, it would take the %username% as the local admin username to add it, because we run it as the local admin)
The copy for the batch file is only necessary so you can run it from anywhere. For example if you would have it on a server's mapped drive it would not work.set /p u=<c:\tempfiles$\temp.txt

You can re-mount your volume from inside the container, in the rw mode, like that:
mount -o remount,rw /mnt/data
The catch is that mount syscall is not allowed inside the Docker containers by default so that you would have to run it in a privileged mode:
docker run --privileged ...
or enable the SYS_ADMIN capability
SYS_ADMIN Perform a range of system administration operations.
docker run --cap-add=SYS_ADMIN --security-opt apparmor:unconfined
(note that I have had to also add --security-opt apparmor:unconfined, to make this work on Ubuntu).
Also, remounting the rw volume back to ro might be tricky, as some process(es) might have already opened some files inside it for writing , in which case the remount will fail with is busy error message.
But my guess is that you can just restart the container instead (as it would be the one running an old version of the app).

I have a dockerized application that uses the filesystem to store lots of state. The application code is contained in the docker image
I am considering a update strategy which involves sharing the volume between two containers, but making sure that at most one container at a time can write to that filesystem.

start container A with /data mounted rw
start container B with /data mounted ro, and a newer version of the application
stop serving requests to container A
for container A, make the /data mount read-only
for container B, make the /data mount read-write

OpenResty allows for loading more complex lua code through files. https://github.com/openresty/lua-nginx-module#init_by_lua_file That is just one directive. There are multiple ways you can load lua code. This way worked for me.
|
I'm using OpenResty with nginx to auto-obtain SSL certs from Let's Encrypt. There's a lua function where you can allow certain domains. In this function, I have a regex to whitelist my domains. After I add a certain amount (not sure the exact amount), I start getting this error:
nginx: [emerg] too long lua code block, probably missing terminating characters in /usr/local/openresty/nginx/conf/nginx.conf:60.
Shrinking down that string makes the error go away.
I'm not familiar with lua, but here's the example code. I have a few hundred domains to add in here.
auto_ssl:set("allow_domain", function(domain)
return ngx.re.match(domain, "^(domain1.com|domain2.com|domain3.com....)$", "ijo")
end)
Do I need to define this string ahead of time, or maybe specify it's length somewhere?
EDIT ok, so I was thinking about this another way. Does anyone see an issue if I were to try this? Any sort of performance issues, or lua related things? Maybe there's a more efficient way of doing this?
auto_ssl:set("allow_domain", function(domain)
domains = [[
domain1.com
domain2.com
domain3.com
-- continues up to domain300.com
]]
i, j = string.find(domains, domain)
return i ~= nil
end)

You need to use SSH to access the repository, not HTTPS.
Change the URL for the remote from https://xxx to git://xxx.
You can use the green button towards the right side of the GitHub repository code page to help you get the correct URL. Change from:

The other thing you need to do is make sure you have an up-to-date local installation of Git. You may run into errors if you have an old version of Git installed.

I hope this script helps, the default path "/" works fine as you have written, but for specific paths like "/api" or "/location"
you need to use the rewrite keyword with regular expression so that the previous path remains the same "http://localhost/" and the forwarding path followed by matching path "/location/somepath" is to be written on the default path.

You can't reliably force the creation of separate objects. Some classes may use tagged pointers. The set of classes doing that can change over time with releases of the OS. A tagged pointer really just encodes the value of the object into a pointer-sized value. It doesn't allocate any memory. By definition, any two objects represented as tagged pointers whose values are equal will have equal "addresses".Also, an init method is just a method. It can return any object it wants. There's no rule that it has to return the receiver. It can release thealloced object it is sent to (self) and return a different object. If it can determine that an existing object (such as the parameter you're passing to-initWithTimeInterval:sinceDate:) meets its needs, it may return that object (with an extra retain). This sort of thing is common in immutable value classes, likeNSDateorNSString.You're going to have to reconsider your supposed need to "make sure 2 different NSDate instances are really two different instances of allocated memory".ShareFollowansweredMar 14, 2016 at 21:04Ken ThomasesKen Thomases89.4k77 gold badges120120 silver badges159159 bronze badges21Tagged pointer details by Mike Ash:mikeash.com/pyblog/…, which are, AFAIK, currently used for NSDate.–jscsMar 14, 2016 at 21:05Yes NSDate does sometimes use NSTaggedDate–Bradley ThomasMar 14, 2016 at 21:22Add a comment| | I'm creating tests where I have to make sure 2 different NSDate instances are really two different instances of allocated memory.

web thinks db runs on the host pointed to by the env variable DOCKER_DB or something like that. Your services should point to that variable (host), not localhost.
The db container exposes ports (via EXPOSE) to its linked containers, again in variables. You can run the db on whatever port you want, as long as it's EXPOSEd.
|
From my understanding of docker compose / fig, creating a link between two services/images is one main reason if you do not want to exposes ports to others.
like here db does not expose any ports and is only linked:
web:
build: .
links:
- db
ports:
- "8000:8000"
db:
image: postgres
Does web thinks db runs on its localhost? Would i connect from a script/program in web to localhost:5432 (standard port from postgresql) to get a database connection?
And if this is correct, how can you change port 5432 to 6432, without exposing?
would i just run postgresql on a different port?

Probably this doc is not 100% and some default variables still require certificates. Try to generate certificates manually.

I've been attempting to follow the instructions listed in:
https://github.com/kubernetes/kubernetes/blob/master/docs/getting-started-guides/docker-multinode/master.md#starting-the-kubernetes-master
but the apiServer won't stay up, it exits with code 255 almost immediately, the last thing in the logs for the container is:
F0222 21:45:10.776761 1 server.go:319] Invalid Authentication Config: open /srv/kubernetes/ca.crt: no such file or directory
I've tried both 1.2.0-alpha.7 and 1.1.2 version of the docker container with:
sudo docker run \
--volume=/:/rootfs:ro \
--volume=/sys:/sys:ro \
--volume=/var/lib/docker/:/var/lib/docker:rw \
--volume=/var/lib/kubelet/:/var/lib/kubelet:rw \
--volume=/var/run:/var/run:rw \
--net=host \
--privileged=true \
--pid=host \

/hyperkube kubelet \
--allow-privileged=true \
--api-servers=http://localhost:8080 \
--v=2 \
--address=0.0.0.0 \

--hostname-override=127.0.0.1 \
--config=/etc/kubernetes/manifests-multi \
--containerized \
--cluster-dns=10.0.0.10 \
--cluster-domain=cluster.local
Only thing I can find, suggested openssl as a dependency, but I've installed that and I'm still getting the error. It seems to suggest I'm missing a certificate, but I cant find any documentation on it - any pointers would be appreciated.

I believe the preferred method of downloading files with AFNetworking is by setting the "outputStream" property.
According to AFNetworking documentation:
The output stream that is used to write data received until the request is finished.
By default, data is accumulated into a buffer that is stored into responseData upon completion of the request. When outputStream is set, the data will not be accumulated into an internal buffer, and as a result, the responseData property of the completed request will be nil. The output stream will be scheduled in the network thread runloop upon being set.
I was having the same problem, solved it by using "outputStream".

You can use the backup directive on the server line and option allbackups in the specific section.
You maybe can also add the weight for the server to define which backup server should be used in priority order.

Let's say I have 3 main servers and 3 backup servers. I want HAproxy to replace a main server with a backup server as soon as it goes down.
To elaborate, let's say Main Server 1 goes down, HAproxy will then still continue to use 3 servers in total, where 2 will be main and 1 will be backup. Similarly, if 2 main server goes down, HAproxy will still use a total of 3 servers, 1 from main and 2 from backup.
Also, once the main server is active again, HAproxy should stop using the backup and switch back to the main server.

The alternative in many cases is to suggest that users disable the firewall entirely orokthe prompt Windows raises when your server ports begin to listen. Both of these are bad options: one risks leaving the machine open to anything and the other trains them to approve security prompts uncritically.You could easily have your applications add and remove themselves as firewall exceptions. They could even disable/enable the firewall, a really bad idea. But it's usually a better idea to add and remove exceptions as part of install/uninstall operations.One place where Microsoft describes the process isWindows Firewall for Game Developers.If your security is so poor you rely on a software firewall alone for protection you can always set "no exceptions" mode on the firewall.

Git is a VCS (Version Control System).
How git's generally used
A feature branch is made where you need to make changes, while work goes on master branch (eg bug fixes) and when feature branch is ready to be added into the master (ie you're ready to add the feature to your master code base) you git merge <feature branch>
How you're using it
Its a bit messy. Try following a regular method where you commit every change you need in your code and in the end merge it with the master.
Another suggestion, use git rebase. (Google it, there are many explaining it visually). Also google git fetch then git merge origin/master master method to reflect changes of master into your working repo. Use rebase, so as to see only one commit (not commit + merge commit) on your repo
Basically, go through a git tutorial. Its easy and you'll understand the basics in less than 10 minutes.

– Kallel Omar
Aug 1, 2018 at 14:39
@KallelOmar But your issue is that you see the past history for those commits you cherry pick. Is that the problem? You do understand that you need not have an extra branch just to make changes and then finally commit into master. You can just commit on master.

when I was working on projects that uses the control system git, each time I want to commit then push my modifs I have ofcourse to git pull before. But the problems that I meet is that in many times git prohibits me to pull because I should before commit my local changes. What I used to do is that I have an other clean git repo where I don't modify it directly, but when I need I use it to git pull then merge my modifs to it using meld, from the other repo where I work. But I think that this way is not the best and lose a lot of time, it's time to optimize it. What I'm thinking to do is that I create an other local branch "work_branch" and commit my modifs to it locally then merge commits from "work_branch" to "master" then push in master after the pull. So the scenario should be like that:
git branch work_branch
git checkout work_branch
#modify in branch work_branch
git commit
git add <files list>
git commit -m "fixes branch work" #local commit
gitk ==> get the id of "fixes branch work" commit (example: 5b099287c229e16c24bfcdbfd6fba384cfe165e6)
git checkout master
git pull
git cherry-pick 5b099287c229e16c24bfcdbfd6fba384cfe165e6 #merge "fixes branch work" commit from work_branch to master branch
git push
The problem that I met is after the third step (#modify in branch work_branch), each modif in the branch work_branch is viewed by the master branch, but what I want is that master branch can see from work_branch only the merged commit after git cherry-pick command.
Is there a way to improve my solution. Or is there an other good way to optimize working with git.

You ask:
How/why can Swift guarantee that object memory allocation will be successful, as implied by a non optional initializer return?
It can't.
What happens if I try to instantiate a Swift object in the minuscule but nonzero chance that the system that is out of memory?
Generally, it will just crash.
Fortunately, the app will often receive memory warnings before it gets to that point (at least if the app is consuming memory slowly enough for the OS to have a chance to supply a warning). So apps often have a chance to free up a little memory before everything goes south. And suspended apps may be jettisoned to free up a little memory, too.
But Swift does not gracefully handle these degenerate scenarios. We are often stuck looking at crash reports, looking for memory related crashes. And when we have memory issues, they often manifest in inconsistent errors (i.e., not always the same line of code), but there are tricks to identify the source of the problem. We will also often “profile” our apps periodically with Instruments to identify memory issues.
|
Many Swift initializers return non-optional objects. This means they cannot be nil and are always successful. However, behind the scenes, Swift has to allocate the memory somehow, and in general memory allocation failure is a possibility. For example, memory returned by C function malloc() should be checked for NULL.

To your question the code you posted is correct and will work.
In my opinion it would be preferable(cleaner\safer) to use C++\CLI as a wrapper to your C++ native classes so all the public methods should receive only managed objects as parameters otherwise just use COM

To be honest, I would not touch COM unless I really have to. I think C++/CLI is very powerful, so why use it for wrapping only? However I agree that public functions should only take managed objects so that the class can neatly integrate in e.g. a C# GUI. The DoStuff function above is private, though.

@Matz i didnt mean that c++\cli should be only a wrapper what i was trying to say is that all the advantages of c++\cli is lost the second your public methods start receiving native poiners so as long as you avoid it everyting should be great and you'll be able to integrate native c++ with c#

I was doing some C++/CLI programming recently in order to integrate some of our company's native C++ classes into .NET. My question may sound trivial, but this is one thing I'm always not sure about:
If there is a ref class with a native pointer, say
public ref class ManagedClass {
private:
NativeClass* pObj1;
NativeClass* pObj2;
void DoStuff(NativeClass* obj);
public:
ManagedClass();
bool Activate();
}
and a constructor like
ManagedClass::ManagedClass() : pObj1(new NativeClass()), pObj2(new NativeClass()) {;}
instances of that class will be created on the managed heap. However, pObj1 and pObj2 do point to objects created on the native heap? So there is no pinning needed to use those pointers, even since they are members of a managed class? Especially, if the DoStuff function calles a external native library function, say
void ManagedClass::DoStuff(NativeClass* obj) {
int returnCode = External::Function(obj);
if (returnCode == 0) return true;
else return false;
}
is there no need to write something like pin_ptr<NativeClass> pinPtr = obj etc.? I guess the situation is different if a reference to the pointer is needed; here, however, I understand that the location of the pointer itself may vary due to memory reallocation, but its content, i.e. a memory adress on the native heap, stays valid since the garbage collector won't touch that memory. Is this correct and code like the one above safe to use?
Thanks for your help!

Can you just use robocopy? This line will copy all files in c:\source and its subfolders that have been modified in the last day, to d:\test.
robocopy c:\source d:\test *.* /s /maxage:1
Of course if you forget to run it one day, you'll miss any files touched that day. So if this is really for backups, the better approach is to use the Archive bit.
robocopy c:\source d:\test *.* /s /m
When a file is created or edited, Windows will clear the Archive bit. robocopy with the /m switch will only copy files with the Archive bit set (meaning only ones that have changed since the last time you ran your script), then sets the Archive bit.

Take a look at https://github.com/marketplace/actions/branch-merge. The example does almost exactly what you want: It merges every pushed branch called "release/*" into "master".
Just change
release/* to bugfix/*
master to development
and you should be set.

Scenario
multiple people are working on multiple branches (one to one relationship) for bug fixes. These branches are designated bugfix/[name-here]
There is a system that automatically syncs with a branch called development.
I'm looking for a way using GitHub, to have all bugfix/* branches automatically merged with the development branch on push.
Considerations
I don't want to have to approve PR's for this as it requires more manual work. I'm looking for a solution that will allow the development branch to be constantly updated and available for testing at any time.
I'm not worried about merge conflicts, since there will not be any cross-over between files between the branches.
I've looked into GitHub actions, but the available actions I've already found seem to be one-to-many merging, where I need many-to-one merging.
New bugfix/[name-here] branches will be created new all of the time, I need a method that will use RegEx or something like that when getting a list of the branches so that every time new ones are created, the GitHub action doesn't have to be updated as well.
PR's will need to be created when something is done testing, and so that particular bugfix/12345 can be merged into master.
I'm under the current assumption that the best case here is for me to write my own GitHub action to achieve what I want.
Question
Does anyone know of an automation I can just plug and play or is there a better way to go about what I'm trying to achieve?

The commenter probably means for you to download and install the release of yt-dlp they linked, rather than whatever's in git for youtube-dl.
Generally an unhelpful comment, since the project yt-dlp diverged from youtube-dl somewhere around 2020-09-22; they're not the same software anymore, and patches from one are going to be really hard to apply to the other. The two projects do have related history, but they've been diverging on purpose for a while.

You may want CURAND.jl, which provides curand_poisson.
using CURAND
n = 10
lambda = .5

Hi, I'm having a hard time installing that package... It also seems to be "phased out" and the dependencies (CUDAdrv) report incompatibility. Which version are you running?

CURAND is part of CUDA.jl nowadays, you shouldn't use the CURAND.jl package (it's old, and as you noticed probably not even installable). The equivalent function in CUDA.CURAND is rand_poisson(!).

Jul 26, 2022 at 14:33

For a stochastic solver that will run on a GPU, I'm currently trying to draw Poisson-distributed random numbers. I will need one number for each entry of a large array. The array lives in device memory and will also be deterministically updated afterwards. The problem I'm facing is that the mean of the distribution depends on the old value of the entry. Therefore, I would have to do naively do something like:
CUDA.rand_poisson!(lambda=array*constant)
or:
array = CUDA.rand_poisson(lambda=array*constant)
Both of which don't work, which does not really surprise me, but maybe I just need to get a better understanding of broadcasting?
Then I tried writing a kernel which looks like this:
function cu_draw_rho!(rho::CuDeviceVector{FloatType}, λ::FloatType)
idx = (blockIdx().x - 1i32) * blockDim().x + threadIdx().x
stride = gridDim().x * blockDim().x
@inbounds for i=idx:stride:length(rho)
l = rho[i]*λ
# 1. variant
rho[i] > 0.f0 && (rho[i] = FloatType(CUDA.rand_poisson(UInt32,1;lambda=l)))
# 2. variant
rho[i] > 0.f0 && (rho[i] = FloatType(rand(Poisson(lambda=l))))
end
return
end
And many slight variations of the above. I get tons of errors about dynamic function calls, which I connect to the fact that I'm calling functions that are meant for arrays from my kernels. the 2. variant of using rand() works only without the Poisson argument (which uses the Distributions package, I guess?)
What is the correct way to do this?

In order to bind your Google Service Account (GSA) to you Kubernetes Service Account (KSA) you need to enable Workload Identity on the cluster.

You need to commit to your local repository, then you can push.

If the metric can have either0or1values, then thesum_over_time(metric[d])calculates the number of1values on the specified lookbehind windowd. For example,sum_over_time(up[1h])returns the number ofupsamples with1value during the last hour. The number of0values then can be calculates ascount_over_time(up[1h]) - sum_over_time(up[1h]).If the metric can have other values than0and1, then Prometheus doesn't provide functions for counting the number of samples with a particular value yet :(There is another Prometheus-like system, which allows counting the number of raw samples with the given value on the specified lookback window -VictoriaMetrics(I'm the core developer of this system). It providescount_eq_over_timefunction for this task.

From your comments on your question, it seems that you haven't tried configuring the path to the report, so it's natural that no coverage data is imported. The analysis cannot intuit where reports are or that it should read them.Having said that, you also indicate that you're generating acobertura.xmlfile, but that's not one of the formatscurrently supported by SonarCFamily for Objective-C.
