I am running ubuntu 16.04 LTS and I'd love to have the launcher on the right hand side, as it is much more convenient, considering the way my monitors are set up.   I know it can be moved to the bottom, but I already have a dock there that I like. It would be more useful to me on the right hand side.  Is there a way to do this?  Currently, I can't find a way to do it. I have checked this and many other forums.
I can’t get used to the new Unity system. I’d like to move the left Unity panel to the bottom of screen (like Windows 7 – more similar is better).  But I can't find a way. Is it possible?
I'm running macOS Catalina 10.15.4 on a 2018 MacBook Pro 15", which has the T2 chip (if anything else is relevant, let me know and I'll update the question.)  I'm a developer and I'm in the process of writing and debugging a C command-line utility that's supposed to take a few miliseconds to run and exit.  My internet connection went down while I was coding (WiFi was still connected, but my ISP was down), and afterwards I noticed that, after compiling the app, the first time I ran it, it took a few seconds to run rather than the expected fraction of a second.  I turned off WiFi (so there was no active network connection), compiled my app again, and ran it -- this time it ran as quick as I would expect.  Turn on WiFi, compile and run again, first run of the app takes longer than expected.  Maybe I'm paranoid, but it sure sounds like macOS is trying to ask Apple's servers for blessing to run my app. Is this the case, or could there be another explanation? If it's indeed the case, can anyone link to an article explaining what's going on under the hood?  UPDATE: as requested, here are timings for an average of three runs of the following command, under different conditions:  touch file.c &amp;&amp; make &amp;&amp; time ./file &amp;&amp; time ./file  The first measurement is the average time for running file for the first time after compilation (the third command in the chain). The second measurement is the average time for running file for the second time after compilation (the fourth command in the chain).  WiFi on, with internet: 347 ms/3 ms.  WiFi on, without internet: 5024 ms/3 ms.  All network connections offline: 24 ms/2 ms. Importance of normal distribution Why did the normal distribution become such a popular (important) distribution? I know one reason is because of CLT. Can you please give more reasons? What is the reason behind "non-static method cannot be referenced from a static context"? I'm bugged by the following that's summarized on p. 109 of .     False theorem: All horses are the same color.      Proof by induction:      $\fbox{$P(n)$ is the statement: In every set of horses of size $n$, all $n$ horses are the same color.}$   $\fbox{Base Case or $P(1)$:}$ One horse is the same color as itself. This is true by inspection.   $\fbox{Induction Step:}$ Assume $P(k)$ for some $k \geq 1$.   $\fbox{Proof of $P(k + 1) :$}$   Since $\{H_1, H_2, ... , H_n\}$ is a set of $n$ horses, the induction hypothesis applies to this set. Thus, all the horses in this set are the same color.   Since $\{H_2, H_3, ... , H_{n+1}\}$ is also a set of $n$ horses, the induction step likewise holds for this set. Thus, all the horses in this set are the same color too.         Therefore, all $n +1$ horses in $\{H_1, H_2, H_3, ... , H_n , H_{n+1}\}$ are the same color. QED.   The issue the instructor was trying to point out is clearly valid. For the case $n = 1$, there is only ${H_1}$. So this case says nothing about possible overlapping elements of each set of $(n + 1)$, for instance $H_2$ in the above proof.    But it was proposed in the class discussion that this was the only problem. Had you been able to prove $P(2)$ true, then a proof of the above format would have been fine.    My interpretation is that yes, you could prove all horses are the same color, if you can prove that any set of two horses will be the same color. But this format would not work.  Why not? The problem I see is that the above proof is for the existence of at least one particular pair of sets of horses of sizes $n$ and $n + 1$, such that in each set, all horses are the same color.  Particularly when the set of size $n$ is a subset of the set of size $n + 1$.  In order to prove the induction step, don't you need to prove that sets of sizes $n$ and $n + 1$, do not necessarily contain the same, overlapping elements?  You could prove that any horse can be added to a set of 2 horses.  Take the last two, and they must be the same color, and so on.  Wwhatever color the first two happen to be, all other horses must thus be the same color.    Am I misinterpreting the example, or am I making a logical error? Thanks in advance.

How to get the Vista taskbar to span multiple monitors? I can't for the life of me get the vista taskbar to span multiple monitors.  I've searched and looked far and wide, and alas the only pseudo-solution i can find is Ultra-Mon, but a) it doesn't quite look the same  and b) i don't want to have to pay for something that Windows really ought to be able to do out of the box.   Does anyone have a solution for this?  Will this get addressed in Windows 7?

How do I calculate standard errors for sums of OLS coefficients? When and why will a compiler initialise memory to 0xCD, 0xDD, etc. on malloc/free/new/delete? I know that the compiler will sometimes initialize memory with certain patterns such as 0xCD and 0xDD.  What I want to know is when and why this happens.  When  Is this specific to the compiler used?  Do malloc/new and free/delete work in the same way with regard to this?  Is it platform specific?  Will it occur on other operating systems, such as Linux or VxWorks?  Why  My understanding is this only occurs in Win32 debug configuration, and it is used to detect memory overruns and to help the compiler catch exceptions.  Can you give any practical examples as to how this initialization is useful?  I remember reading something (maybe in Code Complete 2) saying that it is good to initialize memory to a known pattern when allocating it, and certain patterns will trigger interrupts in Win32 which will result in exceptions showing in the debugger.
