I got two 8-byte strings.  One which is decrypted is:  FF FF FF FF FF FF FF FF   and one which is encrypted is:  16 05 78 B0 0A C2 78 7F    Encryption mode is CipherMode.ECB  I need the key used in DES encryption.
Given a message and DES encrypted form of said message, is it possible to efficiently compute the key used to encrypt the data?
Is it possible to navigate to a Visualforce page from an LWC with parameters and community compatible The LWC framework includes the NavigationMixin.Navigate functionality that can be used to obtain URLs or perform navigation to generated URLs. This supports a number of different page types, as covered in the . What I can't find is how to create a URL to a specific Visualforce page, with parameters and compatible with communities. Using the &quot;web page&quot; navigation type seems wrong to me, since the URL for a Visualforce page varies based on whether access is direct or within a community. Do you know what the correct approach is for navigating from a flexipage via an LWC component to a Visualforce page in the same org, passing the page some parameters? Suppose $f(x)$ and $g(x)$ are continuous function from $[0,1]\rightarrow [0,1]$, and $f$ is monotone increasing, then how to prove the following inequality: $$\int_{0}^{1}f(g(x))dx\le\int_{0}^{1}f(x)dx+\int_{0}^{1}g(x)dx$$ Binomial Distribution Problem - Airline Overbooking Is this sentence grammatically correct?

How to run two Thread Group in a loop - JMeter I'm facing problem here, There are 2 Thread Groups  and both are correlated ( run thread group consecutively is ticked in test plan ).  1st is user thread group and 2nd is Driver thread group. So thread group running concurrently but it is not happening in twice. I've put loop count for 2 they will run each independently after completion of first cycle. I want run this flow such a way that after completion of driver group request next do second iteration (start from user) thread group. So how to do this stuff ?  Loop will be :   User thread group Driver Thread group   After completing this once again start with :   User thread group Driver thread group   like this it should(loop) happen for multiple times I have the following code:  \documentclass[a4paper,12pt]{article} \usepackage[margin=2cm]{geometry} %showframe \begin{document} \tableofcontents \newpage \section*{Abstract} \section{Introduction} \newpage \bibliographystyle{apacite} \bibliography{references} \end{document}   And when I create the table of contents it adds the "References" in the TOC, how can I remove this to not be included in TOC? So far I have tried something like   \bibliography*{references} How can we improve the inconsistent tagging of the questions relating to the recent uproar and associated issues? Question description  There are many questions (~250 in the last five weeks) relating to      sometimes they are about licensing, legal issues, , , , etc.  These questions relate to the same growing polarization between community and Stack&nbsp;Exchange staff. But, it is not easy to search or filter them because the tags are not uniform for those questions, they do not have the same tags.  Could we group all these posts together by some common tag (new or not)? (in addition, maybe we should create less of these questions, they tend to become noise now, water down the core message, and it is ).    Relevance  Overview of current tags (aside from the discussion tag) for the first ten  (           ) questions relating to  (ordered by relevance)                              1   2   3   4   5   6   7   8   9   10     moderators              x           x   x   x     community               x           x   x     etiquette                   x     users                       x     company                     x     moderation                      x     code-of-conduct                     x       x       x     deleted-questions                               x     legal                                                   x   These tags are obviously not the same while it is arguably the same topic (it is even for the same, specific, search term) .  Instead of using multiple searches one might wish to control tracking these question by adding some single relevant tag to watched tags or ignore tags. But, this is difficult when they do not use the same tag. And in the case of ignoring one might ignore too much when the tag is not specific.  Another indicator that these posts need consistent tagging is the fact that there exist highly upvoted answers that function as an archive for these questions (see  and ). But it is only a hack/workaround for the absence of a common tag; they are not an optimal solution.    Why now?  In an older question () it was suggested to create a specific tag. That was rejected at that point. But, now we are several weeks, and many many questions, further. The situation is more escalated than what might have foreseen at that point. The overview becomes a mess and something needs to be done.  See the bump in the image below which indicates that something is 'going on' and it entails a large fraction of the current post. (obtained from ) What type of differential equation is $f'(x) = f(x/2)$ and how do you solve it? I have the following different equation $$f'(x) = f(x/2)$$ with $f(0)=10$. What type of DE is this, and how would you solve it? It seems $f(x)$ is likely to be some relative of $e^x$, since $f'(x) = f(x)$, which is close, but I don't even know what that type of DE is called with that $f(x/2)$ feature, so I'm not having any luck searching for a tutorial. The best candidate I've found was a &quot;delay differential equation&quot;, but that seems more suited to $f(x-3)$ than $f(x/2)$.

Trouble With Persistence After Making a USB Live Thumb Drive Using Pendrivelinux I created a bootable Ubuntu on my 32GB thumb drive (on a NTFS partition) and I selected a persistence of 4GB.  I've noticed that when I reboot from the initial booting off of the USB thumb drive, nothing is preserved.  No apps that were installed nor saved bookmarks.  Is there a way for me to manually force persistence? Does light reflect if incident at exactly the critical angle? A lot of textbooks and exam boards claim that light incident at exactly the critical angle is transmitted along the media boundary (i.e. at right-angles to the normal), but this seems to violate the principle of reversibility in classical physics.  How would a photon or ray travelling in the reverse direction "know" when to enter the higher refracting medium?  It can't know, so I conclude that such light is simply reflected?  Is this correct? In English, the number 0 is treated as plural. It is then:   0 seconds 1 second    1.2 seconds   2 seconds     Shouldn't it be "nobody want to go there," instead of "nobody wants to go there"?  I also saw in TOEFL that "any __" should be used with a singular.  But I see it very common that it is a plural also.  Why is that?  (updated: example, "we don't have any apples any more" vs "If you get any apple, please let me know.") Best way to save a ordered List to the Database while keeping the ordering I was wondering if anyone has a good solution to a problem I've encountered numerous times during the last years.  I have a shopping cart and my customer explicitly requests that it's order is significant. So I need to persist the order to the DB.  The obvious way would be to simply insert some OrderField where I would assign the number 0 to N and sort it that way.  But doing so would make reordering harder and I somehow feel that this solution is kinda fragile and will come back at me some day.
