kandi X-RAY | MBE Summary

MBE is a C library typically used in Security, Hacking applications. MBE has no bugs, it has no vulnerabilities, it has a Permissive License and it has medium support. You can download it from GitHub.

Vulnerability research & exploit development is something totally outside the bounds of what you see in a normal computer science curriculum, but central to a lot of what we RPISEC members find ourselves doing in our free time. We also find that subjects in offensive security tend to have a stigma around them in university that we would like to help shake off. These are practical, applied skills that we're excited to share with those interested in learning. The question this course posed was 'Can we teach a bunch of programmers how to pwn?'.

            How to use k-fold cross-validation instead of train_test_split for Regression Neural Network
            Asked 2021-Dec-24 at 15:25

            We have developed an Artificial Neural Network (ANN), where we split our data into training and testing data with train_test_split. As we want a better and more generalized estimate of our performance scores, we would like to split data with k-fold instead.

            Now, we split the data into 70% training and 30% testing data with train_test_split

            The link you refer to regarding the allocation behavior of GetType() says that it doesn't allocate a new instance every time, it does not say it doesn't allocate at all.

            The first time you call GetType() on an object of a particular type will result in the allocation of a new RuntimeType instance to represent the type, but it's a one-off allocation and subsequent GetType() calls on objects of that type will return the existing instance.

            Including date or time in clocktable report
            Asked 2021-Feb-02 at 01:38

            I didn't think this was going to be hard but I couldn't dig up anything on how to make an org-mode clock table report include the date/time of the task. My report is like this:

            ...

            ANSWER

            Answered 2021-Feb-02 at 01:38

            I'm still pretty new at using clock tables in org-mode, but I came across your question when I was searching for something related to org-mode the other day.

            Something that might help with displaying timestamps relates to using a setting called :properties("CLOSED"). I read about this from a post by @Fabian. When this setting is used, it adds a column named "CLOSED" that should display the date-time-stamp of when a task was "CLOSED".

            Before this works, however, you might need to add the following setting to your .emacs settings file first: (setq org-log-done 'time). I read about this in the org-mode documentation. When this setting is set, and if you are using the "TODO" feature in org-mode: once you set a task to "DONE", a "CLOSED" date-time-stamp should be added to your task. From there, once you refresh your clock table, this new date-time-stamp should appear in the "CLOSED" column.

            Also, from playing around with the :hidefiles settings, I ran into the same problem you had where the "File" column kept showing up even with the :hidefiles setting set. My previous attempt at fixing this (in the earlier answer revision) appears to not actually be doing what I thought it was doing, so I took that part out for now. I have the feeling that this :hidefiles setting issue might be related to the version of org-mode that is being used.

            Update: After trying a more recent version of org-mode (20210201), the :hidefiles setting appears to be working as expected. I installed the new org-mode version using the setting instructions from this documentation page along with the following steps.

            Warning: You may want to use an older version of org-mode depending on your needs. For myself, I tried out a very recent version of org-mode (at the time of this writing), but it might be too new for your purposes. Please consider if you need to try an older version before going through the following steps if you choose to do so.

            1. Add these lines to the .emacs file:

              (require 'package)
              (add-to-list 'package-archives '("org" . "https://orgmode.org/elpa/") t)

            2. Open up a blank emacs editor

            3. Type: M-x list-packages

            4. Navigate to the org option (I picked the 20210201 option, but this might vary) so that the cursor is over the org link

            5. Push the return/enter key

            6. Type: C-x o

            7. Navigate to the Install option so that the cursor is over the Install link

            8. Push the return/enter key

            9. Push y to continue if you want to install this

            10. The package should install at this point

            11. When done, exit out of emacs

            12. Then, open up your .org file

            Also: I added the following setting to my .emacs file, because I generally like to hide the various lists in my .org file when it first gets opened in org-mode:

            Issues with the "Chattering" example in Chapter 2 of Modelica by example
            Asked 2020-Sep-09 at 19:23

            Here is the link of the model:https://mbe.modelica.university/behavior/discrete/decay/#chattering The simulation result for the following result in Dymola 2021 would be:

            model WithChatter(stopTime=1.001s)

            model WithChatter(stopTime=1.5s)

            As we could see, noEvent operator does decrease the CPUTime, but it also causes the system stiff, it would be easier to understand with more explanation about why noEvent would cause the system stiff.

            Based on the event logging of model WithChatter, the simulation process actually uses the minimum time step because the der(x) is not a continuous function. But why doesn't this approach suit the model WithNoEvents?(https://mbe.modelica.university/behavior/discrete/decay/#speed-vs-accuracy)

            If noEvent operator means using the integrator directly, it might require the functions in the equation system have to be continuous? So Does this mean that the model used in the Chattering example(https://mbe.modelica.university/behavior/discrete/decay/#chattering) isn't appropriate, since the function in this model is not continuous?

            ...

            ANSWER

            Answered 2020-Sep-09 at 19:23

            The model used in the chattering example isn't appropriate since it is not continuous, and the error message from dassl is just a boiler-plate message, so the model isn't stiff but discontinuous as you found.

            Markus A has a good point in the related question When to use noEvent operator in Modelica language? that using noEvent to avoid chattering is in general not a good idea, and one should normally try to rewrite the model instead of adding noEvent.

            This specific model is sort of similar to a friction model where you would have

            Techniqes for dealing with non second time units in OpenModelica
            Asked 2020-Jun-26 at 07:19

            Can anyone point me to suitable techniques for working with timescales other than seconds?

            An example is the Lotka-Volterra 'classic model' on the following site: https://mbe.modelica.university/behavior/equations/population/

            The resulting graph is shown with an x-axis from 1-120 seconds, but obviously that is not realistic for the rabbit/fox example. I've adjusted it in the following code snippet to give an idea of what I am looking for (with the assumption that alpha, beta, gamma and delta are actually rates/day).

            My adjustments are a bit clunky and I'm sure there must be a nicer way, I just can't work it out.

            I do want something compatible with the standard library and am using OpenModelica. Thanks!

            I think what you did is correct, and the issue is in the example. As you say, the rates are probably per day, but as it's just a demonstration it's easier to learn from it if the time numbers are not huge.

            An improvements I would make is to omit the second set of parameters, and define the original ones as parameter Real alpha=0.1/(60*60*24) etc.; this way the structure of the code stays simpler, it's clear and directly known what the actual rate comes out to (in case you compare to analytical results or similar), but you can still clearly adjust in the source code.

            Another thing is that you can add parameter in front of your _S quantities, as they will not change during execution.

            Account names are case sensitive, so please check that you're logging in as lab1C. The warzone marks many files as immutable to prevent users from changing them and ruining the game for other players. For example, we don't want the lab2B user to delete its .pass file or /levels files. A few system files, such as /etc/passwd, are also marked immutable. If you would like to modify or delete these files simply remove the immutable flag. We recommend that you add the flag back when you are done making your changes. Posting solutions spoils the fun and grind of the game, and as an academic resource it is likely some of these materials may be re-used by other classes in the future.

If you are ever stuck on a problem or have any questions, you're more than welcome to ask on IRC. This was a very hands on course, so almost every lecture we had students slinging GDB commands or following along with us on screen. The slides were accessory to the lectures and may have gaps or experience brevity at times. With seven of us creating and giving lectures, the slides and teaching styles vary a bit. We did our best to keep them consistent. Sadly we did not record any of the lectures, maybe next time. We're huge fans of reversing / CTF challenges, but reversing is mostly a time problem. With students juggling other classes and work during the school semester, we'd rather them focus on learning the exploitation techniques without the overhead of reversing every binary. The 50 students that enrolled had little to no prior computer security experience. The labs are not designed to be novel CTF challenges, they're meant to be more academic examples paced to crystallize the concepts. Seasoned CTF'ers can probably blow through most of these challenges in a day or two. If XYZ is related to vulnerability research, we're all ears. The course is far from perfect and we are open to hear any feedback for improving it. There's a lot of interest in having it offered again, so it's being considered for Spring 2016. The feedback was almost exclusively positive with the students finding the material challenging, but engaging. We've got dozens of ideas on how to make it even better next time.
