            If you follow the Entity framework model naming convention and your model directly reflects your database table name, column names and so on, you don't need the OnMOdelCreating method. This is because the entity framework will generate the binding behind the scene.

            But, if you want customization, for example, your model field name does not match your database table column name, you configure that on the OnModelCreating method. Another way of using this configuration is called fluent API.

            This doesn't mean you have to use the OnModelCreating method. There are other options for customization. Which is DataAnotation.

            Generate the same computer hardware id. (CHID) like computerhardwareids.exe from Windows SDK
            Asked 2022-Mar-18 at 03:03
            INTRODUCTION

            This thread should be the ending chapter for this first thread from 2014 and this second one from 2017.

            To cut the story short, you simply need to know that the Microsoft Windows SDK includes a program called computerhardwareids.exe, which, as its name suggests, it generates (several) hardware identifiers for the computer, and I would like to replicate the CHID algorithm using .NET to generate the same identifiers as this program generates.

            The list of CHIDS that this program can generate on Windows 10, which is the O.S that I'm using, is listed here:

            1. HardwareID-0 Manufacturer + Family + Product Name + SKU Number + BIOS Vendor + BIOS Version + BIOS Major Release + BIOS Minor Release
            2. HardwareID-1 Manufacturer + Family + Product Name + BIOS Vendor + BIOS Version + BIOS Major Release + BIOS Minor Release
            3. HardwareID-2 Manufacturer + Product Name + BIOS Vendor + BIOS Version + BIOS Major Release + BIOS Minor Release
            4. HardwareID-3 Manufacturer + Family + Product Name + SKU Number + Baseboard Manufacturer + Baseboard Product
            5. HardwareID-4 Manufacturer + Family + Product Name + SKU Number
            6. HardwareID-5 Manufacturer + Family + Product Name
            7. HardwareID-6 Manufacturer + SKU Number + Baseboard Manufacturer + Baseboard Product
            8. HardwareID-7 Manufacturer + SKU Number
            9. HardwareID-8 Manufacturer + Product Name + Baseboard Manufacturer + Baseboard Product
            10. HardwareID-9 Manufacturer + Product Name
            11. HardwareID-10 Manufacturer + Family + Baseboard Manufacturer + Baseboard Product
            12. HardwareID-11 Manufacturer + Family
            13. HardwareID-12 Manufacturer + Enclosure Type
            14. HardwareID-13 Manufacturer + Baseboard Manufacturer + Baseboard Product
            15. HardwareID-14 Manufacturer
            PROBLEM

            I managed to replicate all hardware ids except: 0, 1, 2 and 12

            I found that these four problematic identifiers have in common that they are the only which contains numeric values to append to the string with which to generate the UUID. See the table in this link or read this list:

            • Name | Length | Type

            • System BIOS Major Release | BYTE |Varies

            • System BIOS Minor Release | BYTE | Varies

            • Enclosure type | BYTE | Varies

            I think this is a clear sign that I don't know how to treat those numerical values when building the string with which to generate the UUID.

            QUESTION

            I don't know in which WMI class to find the Enclosure Type value, but it doesn't matter because I really don't care about replicating the HardwareID-12 / Enclosure Type value, but I would like to be able replicate the HardwareID-0, HardwareID-1 and HardwareID-2

            I already know from which WMI class to get the BIOS major and minor release version for HardwareID-0, HardwareID-1 and HardwareID-2, but the problem is that when I append those BIOS values to the string with which to generate the UUID, I end getting a totally different UUID from what computerhardwareids.exe generates.

            My questions are:

            • What I need to do to replicate the same exact generated UUID for HardwareID-0, HardwareID-1 and HardwareID-2?.

            • Maybe I need to treat those numerical values in a special way, applying some format that I don't know when appending them to the string with which to generate the UUID?.

            Please note that I DON'T have experience in reverse-engineering.

            CODE

            This is the code I'm using, written in VB.NET. At its current state I consider it a working solution that replicates (or it should replicate) the same computer hardware ids as computerhardwareids.exe program generate, except hardware ids 0, 1, 2 and 12 for the reasons that I have explained.

            That your cast's operand is a COM object (as evidenced by System.__ComObject being reported as the object type in the error message) may be the source of the problem, because I don't think PowerShell can cast COM objects to other types.

            However, given that PowerShell can dynamically discover members on objects, in many cases where C# requires casts, PowerShell doesn't (and casts to interfaces are no-ops in PowerShell, except when guiding method overload resolution). Similarly, there's no (strict) need to type variables.[1]

            Thus, as you've confirmed, simply omitting the cast of $thMainPipe.InnerObject to type [Microsoft.SqlServer.Dts.Pipeline.Wrapper.MainPipe] worked:

            Asked 2022-Mar-15 at 20:51

            Last week, I signed up for a reverse-engineering coding competition. The rules stated "All input and output to the program must be through the standard streams (stdin and stdout, respectively")." Upon reading that, I looked up their official practice test and started writing my code. I encountered many roadblocks because I was unfamiliar with the sys.stdin.read and sys.stdout.write functions. Then last night while I was researching ways to make my code better, I stumbled upon a coding blog stating the input() function is in fact a form of stdin. I looked around even more on the internet and came across a separate blog from another company that said relatively the same thing. So... is this true? Is input() and print() a form of stdin and stdout I can use for my competition?

            How to create a 2d histogram that draws its colors from a 2d colormap?
            Asked 2022-Mar-10 at 10:08
            Old Question: How to create an HSL colormap in matplotlib with constant lightness?

            According to matplotlib's colormap documentation, the lightness values of their default colormaps are not constant. However, I would like to create a colormap from the HSL color space that has a constant lightness. How can I do that?

            I get that generally, it's not that hard to create your own colormaps, but I don't know how to do this while satisfying the lightness criterion. Maybe this can be done by reverse-engineering the code from the colormap documentation?

            Solution

            I think I found a way to do that, based on this post. First of all, working in the HSL color space turned out to be not the best idea for my overal goal, so I switched to HSV instead. With that, I can load the preferred colormap from matplotlib, create a set of RGB colors from it, transform them into HSV, set their color value constant, transform them back into RGB and finally create a colormap from them again (which I can then use for a 2d histogram e.g.).

            Background

            I need a colormap in HSV with a constant color value because then I can uniquely map colors to the RGB space from the pallet that is spanned by hue and saturation. This in turn would allow me to create a 2d histogram where I could color-code both the counts (via the saturation) and a third variable (via the hue).

            In the MWE below for example (slightly changed from here), with a colormap with constant color value, in each bin I could use the saturation to indicate the number of counts (e.g. the lighter the color, the lower the number), and use the hue to indicate the the average z value. This would allow me to essentially combine the two plots below into one. (There is also this tutorial on adding alpha values to a 2d histogram, but this wouldn't work in this case I think.)

            Currently, you still need both plots to get the full picture, because without the histogram for example, you wouldn't be able to tell how significant a certain z value in a bin might be, as the same color is used independently of how many data points contributed to it (so judging by the color, a bin with only one data point might look just as significant as a bin with the same color but that contains many more data points; thus there is a bias in favor of outliers).

            How would I go about loading something like this in VMware?
            Would it even be possible due to architecture differences?

            VMware simulates an x86 desktop PC.

            You can attach floppy disk, CD-ROM or DVD images to VMware to simulate such a media.

            If you have installed some operating systems in your virtual machine (that runs inside VMware) that contains a tool (similar to 7z) that can extract firmware image files, it makes sense to copy the firmware image to the virtual machine - in this case the file is just a "regular" file for VMware (just like a text document or a PNG image).

            However, VMware itself cannot do anything with a Firmware image for ARM or MIPS.

            I am able to extract the files with 7zip from the binary, as stated. But this removes the ... files ...

            Looking at your screenshot, I doubt if I understood your question correctly.

            If I understand the "binwalk" output correctly, the first file begins at offset 8212 (which is hexadecimal 0x2014), the second one at offset 8276 and the SquashFS image begins at offset.

            So if you want to have the file 2014, you can use the dd tool to extract that file from the firmware image:

            Time-dependent, repeatable pseudo-random number
            Asked 2022-Feb-11 at 16:06

            I need to generate a repeatable pseudo-random number that is dependent on the current time and a server secret. For example, this mechanism should generate a new pseudo-random number every minute. The next minute's random number should not be easily predictable.

            Furthermore, I need to solve this in a stateless fashion (e.g., without storing a generated value in a database). It is possible that a server node might be asked to create such a number multiple times within the same minute, and it needs to generate the same number each time. Also, multiple server nodes (with the same server secret) need to generate the same number within a given time frame. The purpose of all this is not related to solving a security problem (e.g. a token generator), so it's not strictly necessary to use cryptographically secure PRNGs.

            Linear-congruential PRNGs produce repeatable series of numbers when initialized with the same seed, so I could seed the PRNG with the combination of time and server secret and get the first random number it produces to meet my criteria. However, this type of PRNG typically uses a simple formula of next = (current * multiplier + offset) & mask, and, given a few known times and corresponding random numbers, it seems like it would be not all that hard to figure out the server secret (and then predict all future numbers in advance).

            To make this sort of reverse engineering harder, I pull and discard a fixed number (e.g., 1000) of values from the freshly seeded PRNG before I get the "real" random number that I use. My thinking is that reverse-engineering 1000 cycles of next = (current * multiplier + offset) & mask would be significantly more difficult that reverse-engineering just a single cycle.

            I am wondering if my thinking here is even correct. Is it true that figuring out a linear-congruential PRNG's seed is more difficult based on the 1000th value after seeding than it is for the first value of a freshly seeded generator? If so, how many iterations are sufficient before it stops increasing the difficulty?

            If I'm completely off here, what are some better alternatives that fulfill the above stated criteria (repeatability, statelessness)?

            In a way, this is how Time-based one-time passwords (TOTPs) work, so you can use a similar solution.

            To get a time value that changes every N seconds, you can use the following formula.

            floor(timestamp / N)

            Then, you can either turn that into a string or interpret it as bytes. Just pass it to something like HMAC in order to turn it into a pseudo-random value.

            HMAC(SecretKey, floor(timestamp / N))

            Here's a simple implementation in Python. This should be fairly similar in other languages too.

            Yes; "real mode" just means the default operand size is 16-bit, but you (the assembler) can change the default using a size override prefix.

            Of course this only works on 32-bit CPUs (80386 or later), but I doubt you'll care because computers that old won't support PCI anyway (but it's good practice to have an "does the CPU support 32 bit?" check to avoid crashing with no explanation on very old computers).

            For newer computers (with PCI express) "PCI config space" was increased to 4 KiB per function (from the original 256 bytes of PCI config space per function) and a new memory mapped PCI configuration space mechanism was added to make it much faster (without slow IO ports). You won't be able to use memory mapped PCI configuration space mechanism in real mode. Fortunately (for backward compatibility reasons); the old "IO ports" access mechanism is still supported (but only lets you access the first 256 bytes of each function's 4096 bytes) and the extra PCI configuration space for each function is mostly used by things that you won't be able to use anyway (e.g. message signaled interrupts, power management, ...).

            How to reverse the averaging of multiple vectors in JavaScript?
            Asked 2021-Dec-04 at 11:39

            In the code below I mix various flavors of icecream together (chocolate, strawberry, vanilla, & neapolitan) in order to produce a new, never-before-seen flavor of icecream.*

            A flavor is represented by an array where the first element is simply a string, the name of the flavor.

            The second element is a number from 0 to 100 representing the vanilla component, the third the chocolate component, and the fourth the strawberry component.

            Mixing is performed by averaging all the input flavors (arrays) together.

            After mixing, I attempt to determine which flavor the new mixture is most similar to. This is done by taking the sum of the absolute difference of the mystery icecream and known flavors. The smaller the sum, the smaller the difference and greater the similarity.

            In this specific example, the mixture is 6 parts strawberry icream and 1 part of each of the other flavors. Predictably, the strawberry is calculated to be the most similar, followed by neapolitan, because it is itself a mixture.

            This is a good ways towards reverse-engineering the mixture, but I want to go further. I want to determine the precise proportions of each flavor that went into the mixture.

            In this example it would be as stated above: 6 strawberry, 1 vanilla, 1 chocolate, 1 neapolitan.

            Of course, there may be many (infinite?) ways to come up with a given mixture. But I am looking for the most parsimonious possibility.

            For example, 1 part neopolitan plus 1 part strawberry is identical to 4 parts strawberry plus 3 parts of every other flavor. But the former is more parsimonious.

            How would I go about predicting how a mixture was created?

            I don't know what the technical term for this is.

            Install Reverse-Engineering

            You can download it from GitLab, GitHub.
            You can use Reverse-Engineering like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
