How to send GPX file to a GPS device
Why won't QGIS recognize my GPS?
Why does a 95% Confidence Interval (CI) not imply a 95% chance of containing the mean? It seems that through various related questions here, there is consensus that the "95%" part of what we call a "95% confidence interval" refers to the fact that if we were to exactly replicate our sampling and CI-computation procedures  many times, 95% of thusly computed CIs would contain the population mean. It also seems to be the consensus that this definition does not permit one to conclude from a single 95%CI that there is a 95% chance that the mean falls somewhere within the CI. However, I don't understand how the former doesn't imply the latter insofar as, having imagined many CIs 95% of which contain the population mean, shouldn't our uncertainty (with regards to whether our actually-computed CI contains the population mean or not) force us to use the base-rate of the imagined cases (95%) as our estimate of the probability that our actual case contains the CI?   I've seen posts argue along the lines of "the actually-computed CI either contains the population mean or it doesn't, so its probability is either 1 or 0", but this seems to imply a strange definition of probability that is dependent on unknown states (i.e. a friend flips fair coin, hides the result, and I am disallowed from saying there is a 50% chance that it's heads).  Surely I'm wrong, but I don't see where my logic has gone awry... If $a$, $b$, $c$ are the roots of $x^3-6x^2+3x+1=0$, find all possible values of $a^2b+b^2c+c^2a$ Let $a$, $b$, $c$ be the roots of $$x^3 - 6x^2 + 3x + 1 = 0$$ Find all possible values of $a^2 b + b^2 c + c^2 a$. Express all the possible values, in commas.  I've already tried to bash out all the roots, Vieta's Formula, and try to manipulate the equation to become easier to work with. However, Vieta's didn't get me anywhere, and I couldn't find a way to make the equation simpler or anything. Any hints to start this problem? What are the main differences between undergraduate, master's, and doctoral theses? When I did my undergraduate thesis, my adviser was expected big on students expecting them working really hard, so it ended up as a reduced master's thesis (most of the reviewers said that it was an overkill for a B.E).  So because of this, I did my master's thesis pretty much in the same way I did my bachelor's thesis; the PhD dissertation was a different story.  What are the principal differences between these three pieces of research? I've downloaded ubuntu-12.04.1-desktop-amd64.iso via Chrome. Once that was done, I wanted to burn it onto a CD but I can't find the .iso file.   When I opened the Downloads folder, the .iso extension is not there anymore, and it opens with WinRAR for unzipping. I tried unzipping and searching for any ISO files but no luck.   I'm trying to add Ubuntu onto VirtualBox on Windows 7 host OS. Please help. I've never really got how chmod worked up until today. I followed a tutorial that explained a big deal to me.   For example, I've read that you've got three different permission groups:   owner (u) group (g) everyone (o)   Based on these three groups, I now know that:   If the file is owned by the user, the user permissions determine the access. If the group of the file is the same as the user's group, the group permission determine the access. If the user is not the file owner, and is not in the group, then the other permission is used.   I've also learned that you've got the following permissions:   read (r) write (w) execute (x)   I created a directory to test my newly acquired knowledge:  mkdir test   Then I did some tests:  chmod u+rwx test/ # drwx------ chmod g+rx test/ # drwxr-x--- chmod u-x test/ # drw-r-x---   After fooling around for some time I think I finally got the hang of chmod and the way you set permission using this command.    But...  I still have a few questions:   What does the d at the start stand for? What's the name and use of the containing slot and what other values can it hold? How can I set and unset it? What is the value for this d? (As you only have 7=4+2+1 7=4+2+1 7=4+2+1) Why do people sometimes use 0777 instead of 777 to set their permissions?   But as I shouldn't be asking multiple questions, I'll try to ask it in one question.  In UNIX based system such as all Linux distributions, concerning the permissions, what does the first part (d) stand for and what's the use for this part of the permissions? How can I use Netflix on Ubuntu? when upgrading to a 200 amp service panel with service drop coming from bottom underground do I need southern California Edison to come disconnect and then reconnect or can I just do it on my own. I do have a permit. Salesforce1 on focus scroll to the top I have the following validation rule:  AND(  $Profile.Name &lt;&gt; 'System Administrator',  OR(  ISPICKVAL(PRIORVALUE(Level__c), "Archived"),  ISPICKVAL(PRIORVALUE(Level__c), "Closed")  )  )   This validation rule is on the opportunity object, and what I want to achieve is, if the picklist Level__c is either set to Archived or Closed, the opportunity record can only be edited by the System Administrator.  For some reason though, the validation rule also triggers, when I want to set the Level__c to Archived or Closed. But this is not what I want.   Any idea what's wrong with the validation rule? What command do I use to make everyone spawn at one place? because I am making a map and I don't know how to make everyone spawn at one place, the rule place. What is the correct pronunciation of "the"? The is sometimes pronounced &quot;tha&quot; (/ðə/) or &quot;thi&quot; (/ðiː/). Which is the correct pronunciation of this word? Are both correct and used interchangeably at specific places? If the second question is correct, please provide the rule of pronouncing at different places. I have a model which you can see here (camera perspective).    In the second image, you can see how the render turned out.    I'm at my wit's end trying to figure our why it's not showing up in the render. If anyone needs more information, just ask and I'll get it to you. I've already checked the normals and they're not the cause. Execute a program at login I'm running Arch-Linux ARM on a Raspberry Pi.  My project goal is to have a barcode scanner attached to the Pi that forwards the scanned messages to a server in a LAN.  To harden the system against power outages etc. and minimize required user interaction, I wish to set it up so that a certain user is logged in automatically at startup (done and works) and a specific program is to be run at startup (done and works but not as intended).  I've done this so far by adding  exec mono scannerSoftware.exe 127.0.0.1 1234 randomString   to /home/certainUser/.bash_profile so it gets executed only once even when I'm switching back and forth to root (in contrast to bashrc).    The particular problem I am having: When I launch the system, it works as intended (login as certainUser, starting scannerSoftware.exe); BUT if I want to switch users and hit Ctrl+C, it restarts the login process, logging certainUser in again and running the program again => back to where I came from.  My guess as to why this happens is that the sys detects "login not complete, better start it again".  I could circumvent this by spamming Ctrl+C right around the login so that I practically interrupted it. Of course, this is not good practice. Suffice it to say it is not practical at all.  My question: How can I set it up so the program gets executed AFTER login is complete so that Ctrl+C'ing out brings me to a normal bash prompt as certainUser instead of beginning the endless login-cycle?  EDIT: I'm not using any graphical interface or such, only commandline (bash on tty), because when done the system won't even have a display. I would like to set up an APT repository on a server that will provide a couple of packages.  Is there a way to set one up without installing any software on the server?  How do the files have to be organized?    Edit: I must be doing something wrong... can someone please help me? I have the repository at   I'm not sure where or what, but something's misconfigured. I only currently have one package and it's for all architectures.  Here's what's been added to my /etc/apt/sources.list:  deb http://quickmediasolutions.com/apt stable main In any finite graph with at least two vertices, there must be two vertices with the same degree Show that, in any finite graph with at least two vertices, there must be two vertices with the same degree.  HINTS ONLY! What does rate of change actually mean? If we have a function, say, $y=x^2$, then $dy/dx=2x$. Now $y=1,4,9,16...$ for $x=1,2,3,4...$ and $dy/dx=2,4,6,8...$ for $x=1,2,3,4...$ Now as $dy/dx$ represents rate of change of y w.r.t x but I can't understand how these particluar values of $dy/dx$ represent change ? I mean for x=3, the rate of change is 6. What does it mean ? How can I prevent my Wi-Fi connection from glitching? Occassionally my Wi-Fi goes into this weird state where the phone "thinks" I'm connected, but the connection simply doesn't work.  Apps still seem to think I have connectivity, though they can't actually connect to anything, and the status bar still shows that I'm connected to Wi-Fi.  Turning Wi-Fi off and back on resolves the issue, and this occurs on multiple networks.  It seems sort of like whatever service manages the Wi-Fi connection gets killed occasionally.  It usually happens when I've been playing a game (that doesn't access the Internet) for a while or if my phone's been sitting for a while; it never happens while I'm actively using the connection.  I have my Wi-Fi timeout set to "Never" and the normal timeout isn't the issue since my phone regularly lasts several hours without the Wi-Fi dying.  Sometimes it dies a couple times in a day, and recently I went a week or so without it happening.  How can I fix this or prevent the service from being killed (if that's indeed what's happening)?  Shouldn't that be a system process that never gets killed?  (Does Android ever kill system processes other than when they crash?)  Could it be related to TouchWiz?  I have an SGS Vibrant running 2.2 (Bionix NextGen v1, but this has occurred on multiple ROMs). An investigator wishes to produce a combined analysis of several datasets.  In some datasets there are paired observations for treatment A and B.  In others there are unpaired A and/or B data.  I am looking for a reference for an adaptation of the t-test, or for a likelihood ratio test, for such partially paired data.  I am willing to (for now) to assume normality with equal variance and that the population means for A are the same for each study (and likewise for B). What's a good back-up strategy for 1 desktop PC? I'm working on an exercise from functional analysis.  Let $E$ be a vector space and $\|\cdot\|_1$ and $\|\cdot\|_2$ be two complete norms on $E$. Now suppose that $E$ satisfies the following property:  $\bullet$ if $(x_n)$ is a sequence in $E$ and $x,y\in E$ such that $\|x_n-x\|_1\to 0$ and $\|x_n-y\|_2\to 0$, then $x=y$.  Now we want to show that the norms $\|\cdot\|_1$ and $\|\cdot\|_2$ are equivalent.  My idea is as follows: If for any $n&gt;0$, there is an element $x_n\in E$ such that $\|x_n\|_1&gt;n\|x_n\|_2$. Then consider $(\frac{x_n}{\|x_n\|_1})_{n\geq 1}$. Clearly, $(\frac{x_n}{\|x_n\|_1})_{n\geq 1}$ converges to $0$. However, I cann't get a contradicition from this. Maybe my idea is wrong.   In fact, I even don't konw how to show that a Cauchy sequence in norm $\|\cdot\|_1$ is also a Cauchy sequence in norm $\|\cdot\|_2$.   Anyone can give me some hints or a counter example? Thank you very much.
