kandi X-RAY | cfi Summary

cfi is a C++ library. cfi has no bugs, it has no vulnerabilities and it has low support. You can download it from GitHub.

Some binaries to play around with the new LLVM exploit mitigations. Binaries are just a basic 64-bit write8/read8/printf loop with standard exploit mitigations enabled (relro, pie, cookies, nx). I'd suggest reading the Makefile. If there's anything you want me to add/remove, let me know (@yrp604 or email) and I'll try to hook it up.

            It's a bug that hasn't been fixed yet. If the font name contains more than 16 characters it won't be set through the API (but it works from the console). The call to SetCurrentConsoleFontEx() returns success regardless of if the specified font was set or not.

            Model fit of SEM in Lavaan

            Well, first let's check how does the CFI estimator works:

            Usually, SEM programs do not present CFI values below 0, as such if a negative value is obtained, the software shows 0.

            SEM - Analysis of invariance to test regressions
            Asked 2021-Feb-05 at 06:35

            Let's suppose we have a confirmatory factor analysis CFA with three latent variables (visual, textual, and speed) and that we want to add a regression where speed is the outcome and visual and textual are the explanatory variables (that is to say, expand the CFA to a Structural Equation Model SEM).

            Also, let's assume that we have the grouping variable school (2 categories). I want to know if the effects (regression paths) of textual and visual are the same for the two groups or if it is better to have different coefficients for every group.

            How can I achieve this?

            My main idea is to follow an analysis of invariance calculating a Weak model, a Scalar model, a Strict model, and finally a model where regression coefficients aer also constrained to be equal across groups. Then, if the rmsea and CFI for the last model show not major changes I can say that the coefficients can be assumed to be the same; on the contrary, if rmsea and CFI shows that quality of the model gets worse, it is better to use different estimates for every group.

            An alternative would be to make sure the CFA has strict invariance and then add the regression. I could compare the non gruped SEM with the grouped SEM and make a decistion based on the quality of the two models.

            How can I use SetCurrentConsoleFontEx with fonts loaded by AddFontMemResourceEx?
            Asked 2020-Dec-07 at 09:22

            My main goal is to set the console font to Unifont using windows API functions. I can successfully do this by calling AddFontResource with the filename. I would rather use AddFontMemResourceEx because then I can load the font from a Resource. I tested a variety of calls to load the font, and here are the results:

            ANSWER

            Answered 2020-Dec-07 at 09:22

            From the doc,

            This function allows an application to get a font that is embedded in a document or a webpage. A font that is added by AddFontMemResourceEx is always private to the process that made the call and is not enumerable.

            For other content, please refer to zett42's answer,

            You are calling AddFontResourceEx() with FR_PRIVATE flag, which means the font is available only to your process.

            Unfortunately, the console window is not part of your process (GetWindowThreadProcessId() lies in this regard!). It is hosted by a system process ("csrss.exe" before Win 7, "conhost.exe" since then).

            Trying to understand the gcc assembly output for printf()

            I'm trying to learn how to understand assembly code so I've been studying the assembly output of GCC for some stupid programs. One of them was nothing but int i = 0;, the code of which I more or less fully understand now (the biggest struggle was understanding the GAS directives strewn about). Anyway, I went a step forward and added printf("%d\n", i); to see if I could understand that and suddenly the code is much more chaotic.

            For the compiler that you are using it looks like printf(...) is mapped to __printf_chk(1, ...)

            To understand the code, you need to understand the parameter passing conventions for the platform (part of the ABI). Once you know that up to 4 params are passed in %rdi, %rsi, %rdx, %rcx, you can understand most of what is going on:

            Finding a Pattern in an Array of Strings (Java)
            Asked 2020-Aug-06 at 03:43

            What's up, everyone? I am trying to create a simple game where depending on moves a player makes, some character gets appended to their String (likewise for a second player). The game is supposed to detect whether specific characters show up in those Strings, regardless of where in the Strings they appear. Combinations of 3 characters are needed to make progress.

            So, for example, one successful move a player might make would append the characters "c", "d", and "e" somewhere in their String, say "abcde". When the game detects "cde" in their String, they win something. However, if that player's String were instead "ifc4_d'e", the game doesn't detect that win, despite containing the same characters.

            EDIT: There are three code snippets below, but don't be alarmed; the latter two are just the first one but with a slightly altered array and/or findWinPatterns() method.

            Your heart of your question seems to be:

            Given a String of characters, how can I check that all those characters exist in another String

            There are a couple of ways to do this:

            Regex:

            The regex for detecting all of "abc" in a string is "^(?=.*a)(?=.*b)(?=.*c).*". You could either hardcode the regex, or build it from the string like this:
