            Answer:

            Unfortunately doing this directly by attempting to web scrape the search results using UrlFetchApp will not work. You can use third party tools to get the number of search results, however.

            More Information:

            I tested this out using an exponential backoff method which sometimes is able to get past 429 errors when a fetch request is invoked by UrlFetchApp.

            When using UrlFetchApp to either web scrape or to connect to an API, it can happen that the server denies the request on the grounds of too many requests - or HTTP Error 429.

            Google Apps Script runs in the cloud, from a set of IP addresses in a pool that Google own. You can actually see all the IP ranges here. Most websites (especially large companies such as Google) have architecture in place to prevent the use of bots scraping their websites and slowing down traffic.

            Sometimes it's possible to get past this error, using a mixture of exponential backoff and random time intervals as shown for the Binance API (Full Disclosure: this GitHub repository was written by me.)

            I assume that either Google directly blocks the Apps Script IP pool, or there are simply too many people trying the same thing - because with the same techniques I was unable to get any response that didn't involve entering a captcha as we discussed in the comments above and can be seen in the log of the page string.

            What can be done:

            There are many third party APIs that you can use to do this, and I suggest searching for one that meets your needs.

            I tested out one called Authoritas which returns search engine indexing for different keywords. The API is asynchornous, so can take up to a minute to get a response, so a Web App solution needs to be made.

            The flow I used is as follows:

            Send data using over bluetooth using different protocols
            Asked 2021-Jun-14 at 18:48

            I have an app that communicates with a bluetooth device, and I'm trying to replace that app with some code.

            I tried using C# InTheHand nuget, Microsoft's Bluetooth LE Explorer, python's sockets and others to send data and see what happens.

            But there's something I still don't understand - in each way using different libraries I saw in wireshark a different protocol: ATT, RFCOMM, L2CAP...

            When I sniffed my bluetooth traffic from my phone using the app mentioned before, I saw mostly HCI_CMD protocol traffic.

            How can I choose the protocol I want to send? Is there a simple package for that? something to read?

            Do I need to build the packet myself? including headers and such?

            Thank you!

            Update: Using Microsoft's Bluetooth LE Explorer I was able to send a packet that lit up my lamp, starting with 02010e10000c00040012(data)
            Using bleak I was able to send a packet starting with 02010e10000c00040052(data)
            the difference makes the lamp not ligh up and I'm not sure if I can change it via bleak as it's not part of the data I send

            ANSWER

            Answered 2021-Jun-14 at 18:48

            I think what you are showing is that bleak does a write without response while MS BLE Explorer does a write_with_response.

            Looking at the Bleak documentation for write_gatt_char that seems to be consistent as response is False by default

            write_gatt_char Parameters:

            • char_specifier (BleakGATTCharacteristic, int, str or UUID). The characteristic to write to, specified by either integer handle, UUID or directly by the BleakGATTCharacteristic object representing it.

            • data (bytes or bytearray) – The data to send.

            • response (bool) – If write-with-response operation should be done. Defaults to False.

            I would expect the following to have the desired effect:

            I'm running gitlab-ce on-prem with min.io as a local S3 service. CI/CD caching is working, and basic connectivity with the S3-compatible minio is good. (Versions: gitlab-ce:13.9.2-ce.0, gitlab-runner:v13.9.0, and minio/minio:latest currently c253244b6fb0.)

            Is there additional configuration to differentiate between job-artifacts and pipeline-artifacts and storing them in on-prem S3-compatible object storage?

            In my test repo, the "build" stage builds a sparse R package. When I was using local in-gitlab job artifacts, it succeeds and moves on to the "test" and "deploy" stages, no problems. (And that works with S3-stored cache, though that configuration is solely within gitlab-runner.) Now that I've configured minio as a local S3-compatible object storage for artifacts, though, it fails.

            The answer is to bypass the empty-string test; the underlying protocol does not support region-less configuration, nor is there a configuration option to support it.

            The trick is able to work because the use of 'endpoint' causes the 'region' to be ignored. With that, setting the region to something and forcing the endpoint allows it to work:

            How can I block all outside US traffic to my Azure SQL? I've used Front Door WAP with my App Services. How do you do this with an Azure SQL instance ? I have already set Firewall rules.

            thx in advance

            ANSWER

            Answered 2021-Jun-14 at 12:38

            The easiest way to accomplish this is to only allow a few IP's to communicate directly with the SQL server and "allow-list" those few IP addresses via IP Firewall Rules. This is also the most secure method. It is recommended if you have a VM in Azure connecting to the DB, you assign that VM a static IP address.

            If that is not possible, you can enable Private Link. Private Link allows you to connect to a server via a private endpoint. A private endpoint is a private IP address within a specific virtual network (VNet) and Subnet.

            Once Azure SQL is connected to a VNet, You can filter network traffic between subnets using either or both of the following options:

            • Network security groups: Network security groups and application security groups can contain multiple inbound and outbound security rules that enable you to filter traffic to and from resources by source and destination IP address, port, and protocol. To learn more, see Network security groups or Application security groups.
            • Network virtual appliances: A network virtual appliance is a VM that performs a network function, such as a firewall, WAN optimization, or other network function. To view a list of available network virtual appliances that you can deploy in a virtual network, see Azure Marketplace.

            Is probing of a Pod retried after a readiness probe fails
            Asked 2021-Jun-14 at 12:32

            readinessProbe: Indicates whether the container is ready to respond to requests. If the readiness probe fails, the endpoints controller removes the Pod's IP address from the endpoints of all Services that match the Pod. The default state of readiness before the initial delay is Failure. If a Container does not provide a readiness probe, the default state is Success

            If the readiness probe fails (and the Pod's IP address is removed from end point), what happens next? Will the Pod's readiness probe conditions be checked again? Will it check again after initial delay? Is there any chance the Pod's IP address is added to the end point again (if the Pod self healed after readiness probe fails)? Will that Pod receive traffic again incase if it's healed?

            How to wrap OpenVPN and HTTPS traffic in one TLS connection?
            Asked 2021-Jun-14 at 06:54

            I am trying to create a single TLS connection from a client to a server. Inside this tunnel, I would like to have two different types of streams: HTTPS traffic that I want the server to forward to a specific API server, and OpenVPN traffic(which is a combination of TLS and a TCP data stream). I am looking into WebSocket to do so, but can't find information on how to forward the stream to the correct destination (OpenVPN vs HTTPS API server) once it reaches my server. Is WebSocket a good solution for this? Is stunnel a better option? Are there existing solutions that offer this functionality?

            ANSWER

            Answered 2021-Jun-14 at 06:54

            I've ended up solving this using SSLH and ghostunnel: on the client, I have started a ghostunnel listening on 127.0.0.1:8443 and forwarding the TLS-wrapped traffic towards a ghostunnel server I have in the cloud (listening on 443). I have directed my OpenVPN client to connect to 127.0.0.1:8443. I have also directed my HTTPS client to connect to 127.0.0.1:8443. On the server side, the traffic coming out of the ghostunnel server is funnelled into an SSLH server which in turn has two rules: forward TLS traffic to my webserver, and OpenVPN towards my OpenVPN server. The solution works great!

            AWS Load Balancer Controller successfully creates ALB when Ingress is deployed, but unable to get DNS Name in CDK code
            Asked 2021-Jun-13 at 20:44

            I originally posted this question as an issue on the GitHub project for the AWS Load Balancer Controller here: https://github.com/kubernetes-sigs/aws-load-balancer-controller/issues/2069.

            I'm seeing some odd behavior that I can't trace or explain when trying to get the loadBalacnerDnsName from an ALB created by the controller. I'm using v2.2.0 of the AWS Load Balancer Controller in a CDK project. The ingress that I deploy triggers the provisioning of an ALB, and that ALB can connect to my K8s workloads running in EKS.

            Here's my problem: I'm trying to automate the creation of a Route53 A Record that points to the loadBalancerDnsName of the load balancer, but the loadBalancerDnsName that I get in my CDK script is not the same as the loadBalancerDnsName that shows up in the AWS console once my stack has finished deploying. The value in the console is correct and I can get a response from that URL. My CDK script outputs the value of the DnsName as a CfnOutput value, but that URL does not point to anything.

            In CDK, I have tried to use KubernetesObjectValue to get the DNS name from the load balancer. This isn't working (see this related issue: https://github.com/aws/aws-cdk/issues/14933), so I'm trying to lookup the Load Balancer with CDK's .fromLookup and using a tag that I added through my ingress annotation:

            Don't worry about deleting the workspace. As log analytics workspace is a unique environment and it can be created to monitor those rescoures which have deployed for a long time. What I mean is that the workspace and other resourse is low coupled.
