    [Disaster Recovery Plan] Simulation vs Parallel Test

    Posted: 06 Apr 2021 09:15 PM PDT

    Hi, I am quite confused on whether this is considered a simulation or parallel test. After viewing both Ref 1, and Ref 2, it did seem like both the description fit the bill, however I am only allow to pick one.

    Anyone who is familiar with DRP, care to share your opinion with me.

    Question: As part of an exercise, the senior management has instructed the IT department staff to move some of the network systems to an off-site facility and redeploy them for testing. All staff members must ensure their respective systems can power back-up and match their golden image. Any inconsistencies found, must be formally documented.

    Need Suggestion about Character Recognition

    Posted: 06 Apr 2021 10:03 PM PDT

    I want to recognize characters from a blurred or cut-out (some characters are visible and some are blurred or cut-out for example "MA 1008" in this image 100 is clearly visible but 8 is blurred or cut-out). How i achieve this in deep learning.

    I know how to draw a Turing machine for adding two numbers, however I'm unsure when it comes to more than two numbers

    Is the syslog family suitable for logging in distributed systems?

    Posted: 06 Apr 2021 05:06 AM PDT

    The syslog family (syslogd, rsyslogd, syslog-ng, ...) has been used by Linux and Unix for years as their only logging systems, and used for logging over networks between computers.

    Is the syslog family commonly used for logging in distributed systems? If not, why not?

    Why is fluentd or alike more approriate for distributed systems than the syslog family, if that is true? (I was wondering why reinventing tools.)

    Thanks.

    How does a tcp terminating load balancer return the response if it's terminating the request at the load balancer level?

    Posted: 06 Apr 2021 01:16 AM PDT

    If it says that the connection is terminated at the load balancer, how is the final response being given to the client?, sorry I know it's a very noob question

    Discussion about a decentralised and distributed accurate timing system.

    Posted: 05 Apr 2021 09:19 AM PDT

    Last night, I was thinking about how cellular automata propogate by updating all states at some given event, for example, every second. This is a beat - a pulse - a cycle - a regularly recurring event. It's a timing event for a system. The second is defined based on hyperfine splitting, etc. The physical world is governed by such accurate timing events. This led me to what I consider to be a significant understanding.

    When it comes to decentralsied and distributed systems such as blockchain platforms, these accurate timing systems don't exist from what I can tell and there's no way to measure time with significant accuracy.

    It also seems to me that blockchains themselves could function as such timing systems with blocks playing the role of beats. For example, the goal for the bitcoin blockchain is to create a new block every 10 minutes. You could say that the blockchain has a pulse of 1 beat per 600 seconds on average. This kind of simulates a heartbeat - a timing system with a variable beat. It can speed up and slow down and "resting" will return it to normal. What these distributed systems need is a blockchain equivalent to a fixed rate timing system like hyperfine splitting as opposed to a variable one.

    So, what I'm hoping to achieve with this post is to hopefully start a discussion about this subject. Is it possible to create a blockchain type system with incentives but with a fixed rate block creation?

    Is such a system even necessary or could creating blocks more quickly have the same effects, for example, 1000 blocks per second instead of 1 block per 600 seconds? What are the limitiation, etc?

    Beginner noob question

    Posted: 05 Apr 2021 11:58 PM PDT

    First year Cs student. Is there possibly a website that explains terms and pc hardware conditions (bottle neck, when it happens or cpu heat etc) in simple words and in one place? I searched and couldn't find, thought no harm in asking. Thanks in advance

    How to create new pages using PHP?

    Posted: 05 Apr 2021 02:43 PM PDT

    Hello, i'm fairly new to programing and am currently building a sort of reddit clone. my backend code is written in PHP. I want to have a feature similar to the create subreddit system on reddit. The user would click a button input a title and description and then the application would create a new page using that data. I know this is possible using Java but I haven't been able to find anything for PHP. Any and all help is appreciated, Thanks!

    Is it possibel to live-edit your webcam?

    Posted: 05 Apr 2021 01:11 PM PDT

    Is it possible to edit the frames of the video that my webcam records before it is sent to the application that's using it?

    For example, can I edit my webcam's data—blur, for example—before it gets sent to zoom or skype to be displayed.

    I want to see if I can apply custom image processing filters to my webcam!

    I imagine I will somehow bring the stream of video from a webcam and then edit it using some script, then send it back to the computer?

    Thank you in advance.
