What precautions should be taken after the process of cooking?
What do I need to know about temperature and food safety?
My Windows 10 notebook died but fortunately I was able to rescue the hard drive and put it into another PC.   Unfortunately, the other PC can't open the C/Users/Joe folder. What do I have to do to open the folder? I understand that in a lot of big-lab fields it is common for the principal investigator to append their name to a paper even if they did not write the paper, design the experiment, or collect data since they spend energy securing funding, and managing the whole lab. What about for small labs?  What are the requirements for a supervisor to be included as an author on a paper, as opposed to just appearing in the acknowledgements? If you are working on your own projects independently of your supervisor, but using funding provided by your supervisor (how does this change when the funding provides resources versus just your salary), are you suppose to add them as authors or just acknowledge the source of funding? Delay in 4-bit ripple carry adder? In pic below I have drawn a full adder and mentioned their delays, please help me to verify my answer. Copying protected files between servers in one line? I'd like to copy squid.conf from one server to another.   The servers don't talk to each other. I'd like to go through my workstation. Both servers have the file, so it will be overwritten on the target. The files have 600 permission and are owned by root. root login via ssh is disabled (PermitRootLogin no). I'd like to do it in one line, if possible, since it will be a part of a setup guide.   I know to do  ssh source 'tar czpf - -C /etc/squid/ squid.conf' | \     ssh target 'tar xzpf - -C /etc/squid/'   to copy files between servers and preserve permissions. However, in this case I will get "Permission denied".  I also know I can do this:  ssh -t source 'sudo cat /etc/squid/squid.conf'   This way the -t allows sudo to ask for the admin password before outputing the content of the file.  The problem is, I don't know how to combine those techniques into something that will ask for the sudo password on each server, and transfer the file to its destination. Is this possible?  UPDATE: Here's the best I could come up with:  ssh -t source 'sudo tar czf /tmp/squid.tgz -C /etc/squid squid.conf' &amp;&amp; \ ssh source 'cat /tmp/squid.tgz' | \     ssh target 'cat &gt;/tmp/squid.tgz' &amp;&amp; \ ssh -t source 'sudo rm /tmp/squid.tgz' &amp;&amp; \ ssh -t target \     'sudo tar xzf /tmp/squid.tgz -C /etc/squid &amp;&amp; sudo rm /tmp/squid.tgz'   Calling this a one-liner seems like a stretch. I think I'll just break it down to separate steps in the setup guide. Is a contradiction enough to prove a set equality to $\varnothing$? I am looking at this:    I need to create a boot disk to test Ubuntu to make sure it will run on a PC (Compaq Mini CQ10-120LA) I was given. I can create the boot disk off of a Mac (in English) or Windows (but Windows is in Spanish and foreign to me).   Questions:     What format do I choose for the USB stick? (I wish the instructions stated this). What is Dash? (Will I know when I run the installer?) Can I do this from a Mac or Windows computer? Or only from Ubuntu? Captured variable in a loop in C# I met an interesting issue about C#. I have code like below.  List&lt;Func&lt;int&gt;&gt; actions = new List&lt;Func&lt;int&gt;&gt;();  int variable = 0; while (variable &lt; 5) {     actions.Add(() =&gt; variable * 2);     ++ variable; }  foreach (var act in actions) {     Console.WriteLine(act.Invoke()); }   I expect it to output 0, 2, 4, 6, 8. However, it actually outputs five 10s.  It seems that it is due to all actions referring to one captured variable. As a result, when they get invoked, they all have same output.  Is there a way to work round this limit to have each action instance have its own captured variable? Helical motion of charged particle in external magnetic field Let $f:[0,+\infty)\to\Bbb R$ be a function bounded on each finite interval. I want to show that if $\lim\limits_{x\to+\infty}[f(x+1)-f(x)]= L,$ then also $\lim\limits_{x\to+\infty}\dfrac{f(x)}x = L$ How do I size a UITextView to its content? In LWC am trying to iterate over a list and show the details from the list, this is working correctly , but as a header want to show the record number in a displayed order, below is desired outcome and simplified sample code.  Desired OutCome:   Employee Record 1: A  Employee Record 2: B  Employee Record 3: C   JavaScript:  Var empNames = ["A" , "B" , "C"];   HTML:  &lt;template for:each={empNames} for:item="employee" for:index="index"&gt; Employee Record{index} {employee} &lt;/template&gt;    Actual outcome  Employee Record 0: A  Employee Record 1: B  Employee Record 2: C   I understand as i am using {index} which indicated the position of element in an array which starts from 0 my actual outcome also starts like Employee Record 0 instead of Employee Record 1, but is there a simple way without writing much logic on JS to handle this in html and to make my headers starts from 1 instead of 0? Is mass converted into energy in exothermic chemical/nuclear reactions?  My (A Level) knowledge of chemistry suggests that this isn't the case. In a simple burning reaction, e.g.   $$\mathrm{C + O_2 \to CO_2}$$  energy is released by the $\mathrm{C-O}$ bonds forming; the atoms lose potential energy when they pull themselves towards each other, in the same way that a falling object converts GPE to KE. There are the same number of protons, electrons etc. in both the reactants and products. I would have assumed that this reasoning extends to nuclear fission/fusion as well, but one physics textbook repeatedly references very small amounts of mass being converted into energy in nuclear reactions.  So I just wanted to know if I was wrong about either of these types of reactions, and if so, what mass is lost exactly? I have some survey response data that are inconsistent and I'm not sure what is the best way to handle them.  This is the nature of the inconsistency:    Have you ever had a food poisoning episode that you think might have been caused by the food in a particular restaurant ? a) Yes b) No Did any of these episodes prevent you from eating at that restaurant again?  a) Does not apply, never have had a food poisoning episode b) Yes c) No Following these episodes, did you come back to your normal condition after 24 hours?  a) Does not apply, never have had a food poisoning episode b) Yes c) No   I believe that the intent of the designers of the survey was that anyone answering "No" to 1) should answer "Does not apply" to 2) and 3), but that's not how it worked. A large group of respondents picked "No" for 1) and "No" for at least one of 2) or 3).    What is the best way to deal with this inconsistency?    Where are some good references (books, papers, websites, etc.) to look at discussions and solutions for issues of this kind, and data cleaning in general? Elected moderators can nominate themselves , and I can nominate myself again, despite having won the first round of election.    I understand this isn't going to be easy to fix, given that SE only knows about community mods, employees and developer roles, and pro-tempore mods need to be able to nominate themselves. Are the rationals a closed or open set in $\mathbb{R}$? How can I raise a soldiers hacking ability? My main specialist seems to have a hard time hacking stuff. How can I make him better at it? How do you "OR" criteria together when using a criteria query with hibernate? We have no mention of Voldemort in Harry's sixth year. So, I was wondering- what could Voldemort have been doing? Placing null at the end of the List I have a beamer frame with about 150 slides on it.  I want article and handout mode to only show frame 92.    Reading section 8.6.2 of the beamer manual it seems like I should be able to do something like  \begin{frame}&lt;handout:92&gt; ... \end{frame}   but that seems to have no effect--all 150 slides are set in handout mode, overlaying (making the result unreadable).  I have gotten the effect I want by taking all commands within the frame that have an overlay specification and adding "| handout:0" to make them not appear in handout mode.  Annoying, but works.  But for my 150-slide frame the different slides are generated by a PGF \foreach loop so I can't code slide 92 differently from the rest.  But can I do this at the frame's overlay specification?  It seems that the frame's overlay spec really acts differently from other commands.  If I only do  \begin{frame}&lt;92&gt;...\end{frame}   then I get only slide 92 in beamer mode but all slides in article or handout mode.
