            How do I get the raw bytes received in from BLE in the android BLE sample program?
            Asked 2021-Jun-15 at 04:38

            I am using the BluetoothLeGatt example from here: https://github.com/android/connectivity-samples/tree/master/BluetoothLeGatt

            Assume BLE connection, service and characteristic detection have all happened properly. The following data being sent is value of a characteristic.

            From a custom BLE device, I am sending an array of bytes to the smartphone, for example, something line {0x00, 0x01, 0x02, 0x03, 0x04}. In the android program this is received inside the onReceive() function inside BroadcastReceiver mGattUpdateReceiver in DeviceControlActivity.java

            The example you are using receives the data as a byte array already, but it appends hex representation to the data as string. This is why you get your data in both representations.

            You will need to change the example in the file BluetoothLeService.java on line 149. It is currently reading
            intent.putExtra(EXTRA_DATA, new String(data) + "\n" + stringBuilder.toString());

            and you would need to change it to
            intent.putExtra(EXTRA_DATA, new String(data) + "\n");

            if you want to receive only the string representation.

            β€œ500 Internal Server Error” with job artifacts on minio
            Asked 2021-Jun-14 at 18:30

            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:

            1. Security Group allows inbound ALL ICMP is from self (self reference the security group id)
            2. Security Group outbound ALL TRAFFIC is allowed.

            2 issues: Python Pickle .dat append to list and tkinter checkbutton issue
            Asked 2021-Jun-11 at 04:24

            I've had a lot of issues with this application because I am simply not good enough yet, but I am almost done with it and just want to finish it so I can move on to some slightly lower level projects.

            It is a tkinter to-do application.

            You can add a Task to a listbox

            For every Task, there are some associated attributes, among others: ````self.value = vandself.connectivity = c. The hierarchy of the tasks displayed in the listbox is determined by the value of val_var``` (e.g. the higher the value the higher on the list it will be displayed).

            The Task and the associated attributes are determined by the user's input when one creates another task.

            The Task is appended to a list task_list and after the user has added more than 1 task to the list, the next time one adds a task one will have the option to check existing tasks that it is connected with somehow.

            The list is sorted so the task with the highest value (val_var) is displayed at the top of the Listbox and the task with the lowest value is displayed at the bottom of the Listbox. You can "Save tasks" and then launch the application at a later time where you can then "Load tasks".

            Issue 1:

            After loading tasks from a saved .dat file, it displays in the Listbox in the order it was saved in. However, if you now want to add another task at least two undesirable things happen:

            1. The tasks now loaded into the Listbox are now not displayed as checkbuttons upon adding a new task.
            2. When you add another task (again this is after loading the .dat file) the Listbox will delete what was just loaded and the Listbox will only display the newly added task.

            I am somehow interested in being able to load the Tasks instances from the .dat file and then append them to the task_list so they are a part of the current session/instance of the application, but I don't know how one might do that.

            Issue 2:

            On a given session where tasks have been added to the Listbox, they can be deleted from the listbox using the "Delete task" button. The selected task in the Listbox is deleted, but it is not the same task that is deleted from the task_list.

            To test what I mean by this one can add a couple of tasks to the Listbox and then delete one after doing so. Notice upon trying to create yet another new task that the one just deleted from the Listbox will still be shown as a checkbutton - however, another task that wasn't just deleted has now vanished as a checkbutton.

            Any help with these issues will be sincerely appreciated.

            Your problem is fairly simple. You need to save the objects of the Task class instead of saving the strings present inside the Listbox.

            That said you should never give bare except clause like the one you did, always specify the exception you want to catch. You will find it hard to find the exact problem if you don't.

            Janus Graph backend cassandra vs Bigtable
            Asked 2021-Jun-10 at 19:37

            I am planning to use Janusgraph for building graph of different uses our team handles and I see that janus graph has option to use BigTable or Cassandra as storage backend. I am looking for any recommendation on which backend is more optimal/performant ( I am mainly talking about gremlin query performance on 2 hop neighbor of a node ) with JanusGraph.

            I understand that performance is pretty subjective and varies based on datasize/graph connectivity and use case so best approach will be to try out myself, which I am planning to do. But has anyone else has done similar performance comparison ? Is there any general recommendation about storage backend here ?

            ...

            ANSWER

            Answered 2021-Jun-10 at 18:14

            You're right in that performance is both:

            • subjective
            • depends largely on data size

            I can tell you that I have done this exercise as well. To that end, I think it's important to share this comparison from DB-Engines.com.

            In terms of performance, the biggest thing I'd be looking at is how each handles consistency. As a general rule, databases which enforce stronger levels of consistency typically have to sacrifice performance.

            • BigTable == strong-consistent
            • Cassandra == eventually consistent

            Other factors worth considering, are the fact that BigTable limits you to Google Cloud (GCP). And if you don't want to lose performance over the network, you'll also need to pay for more (Janus) instances on GCP for data locality.

            In terms of raw DB-Engine "score," Cassandra is currently at 114.112, while BigTable is at a paltry 3.582. These scores will change month-to-month, but in general this signifies that Cassandra has a much stronger community around it. Similarly, Cassandra has 18182 questions on this site, while BigTable only has 449. Bottom line, is that it'll be much easier to get support and answers to questions.

            Just based on the underlying strength of the community, Cassandra is the better option here.

            Having supported JanusGraph on Cassandra for the last few years, I can tell you that overall it's been solid. The difficulties tend to come into play with bulk data loading. But outside of that, things seem to run pretty well.

            SQL Server Configuration - Disabling the "Allow Remote Connections to this Server" Option
            Asked 2021-Jun-07 at 20:44

            My organization had a security audit and was told that we need to DISABLE the "allow remote connection to this server" option for all of our SQL Servers. What impact would this have on connection to the SQL Server via Management Studio (SSMS) from a client machine/desktop or from a web app that might use a connection string or any other external app? All of the documentation I see regarding connectivity issues to a SQL Server seem to include "ENABLING" this option as a solution. Is there a workaround that will allow us to disable it but still allow the access we need from the target clients?

            We have multiple versions that we would be doing this on 2012, 2014, 2016 and 2017.

            ...

            ANSWER

            Answered 2021-Jun-07 at 20:44

            The "allow remote connection to this server" option in SSMS (Server Properties-->Connections) is actually the remote access configuration option. This option is often mistaken for enabling remote network connectivity via SQL Server Configuration Manager, which might be what you've read.

            The remote access option is a long deprecated feature that will be removed in a future SQL Server version. It will likely have no impact but your environment may be atypical so you may want to first test in a pre-prod environment before making the change in prod.

            Below is the excerpt from the documentation.

            The remote access option controls the execution of stored procedures from local or remote servers on which instances of SQL Server are running. This default value for this option is 1. This grants permission to run local stored procedures from remote servers or remote stored procedures from the local server. To prevent local stored procedures from being run from a remote server or remote stored procedures from being run on the local server, set the option to 0.
