I'm trying to boot ubuntu on my windows 10 desktop but can't as I get this message: "Initramfs unpacking failed: Decoding failed"

I installed the VMware bundle on my Ubuntu 11.04 successfully but when I open it it gives me this window     and I don't know the path to this C headers. I am trying to monitor multiple JVMs running on different servers through an ssh tunnel.  Thanks to one of the UNIX gurus here, I have managed to get this running for a single server by:   Run jstatd on the target server Set up Visual VM to use 9696 as its socks proxy port. On my local PC, run:  ssh -L 2222:server1:22 bastion-host  On my local PC, run:  ssh -o port=2222 -D 9696 -L 1099:localhost:1099 localhost    This does the trick. Now when I try and tunnel to a second server I try:   On my local PC, run:  ssh -L 3333:server2:22 bastion-host  On my local PC, run:  ssh -o port=3333 -D 9696 -L 2099:localhost:1099 localhost    However, the last step complains with:  bind: Address already in use channel_setup_fwd_listener: cannot listen to port: 9696   Has anyone managed to do something similar?  Update:  The reason this is so complex is that jstatd is an RMI server application:    As with RMI applications, these register with an rmiregistry. Using rmi through a firewall requires me to use SOCKS as described here:    Unfortunately, visualvm only lets me set the SOCKS proxy port once, and the -D option won't allow me to forward the same local port to both servers... How can I deal with "Low on Space" messages on my Android? I keep getting the "Low on Space: Application data space is low. To free up" [the rest is cut off] message.  I've moved every app I can over to the SD card, cleared the cache, compacted my K9 mail cache.  Advanced Task Killer (ouch!) says I have 98M Available Memory  File Manager says I have 223M/748M (29%) free.  That's not so bad -- but I'm stuck in the no-updates scenario. The market downloads won't really start, gmail won't update, etc. I've rebooted several times, and nothing changes. Aaaargh.  What can be done, other than uninstalling everything ? Maximum length of a USB Cable? How to show that $\int_{0}^{\pi}{\sin^5 x\over 1+\cos^3 x}\mathrm dx=\ln 3?$ Given the integral $(1)$     $$\int_{0}^{\pi}{\sin^5 x\over 1+\cos^3 x}\mathrm dx=\ln 3\tag1$$   This integral seems to be quite tough, I can't even know where to start. I have try substitution $u=1+\cos^3 x$ and $u=\cos^3 x$, can seem to remove the x variables.  We have the following identities   $$\sin^5a={5\over 8}\sin a-{5\over 16}\sin 3a+{1\over 16}\sin 5a\tag2$$  $$\cos^3 a={3\over 4}\cos a+{1\over 4}\cos 3a\tag3$$  We may write $(1)$ as  $$\int_{0}^{\pi}{\sin x(1-\cos^2 x)^2\over 1+\cos x(1-\sin ^2 x)}\mathrm dx\tag4$$  $u=1-\sin^2 x\implies \mathrm du=-2\sin x\cos x\mathrm dx$ then $(4)$ becomes  $${1\over 2}\int_{0}^{1}{(1-u)^2\over \sqrt{u}+u^2}\mathrm du\tag5$$  $u=v^2\implies du=2vdv$ then $(5)$ becomes  $$\int_{0}^{1}{(1-v^2)^2\over v+v^4}\cdot{v\mathrm dv}\tag6$$ Simplify to  $$\int_{0}^{1}{(1-v)(1-v^2)\over 1-v+v^2}\mathrm dv\tag7$$  I guess using partial decomposition of fraction and integrate term by term, seem lengthy process  How else can we prove $(1)$? I recently upgraded Windows 7 to Windows 10. The biggest issue I have now is that the Windows Search service no longer works, making the Start menu mostly unusable.  If I go to Indexing Options in the control panel I see that Indexing is not running and the list of paths to index is empty.  Going to advanced options, the current index path is empty, and the new path is empty too. This is true even if I try to use the "New Index" button.  Using the troubleshooter won't help since the service doesn't start. If I try to manually start the "Windows Search" service, I get the error  "Error 3: Unable to find specified path" (this is the rough translation, the original message is in my language).  What can I do to find out which path/file is missing ? I tried to check with Process Monitor, but the only file (beside system libraries) the SearchIndexer.exe try to access seem to be c:\ProgramData\Microsoft\Search\Data\Application (everytime the service is started the whole folder c:\ProgramData\Microsoft\Search is deleted and recreated) and C:\Windows\System32\config\systemprofile (which exists).  Edit: all available updates are installed, and issuing      SFC /scannow   Doesn't reveal any issue Proof that $\bigcap_{a\in A} \bigg(\, \bigcup_{b\in B} F_{a,b} \, \bigg) = \bigcup_{f\in ^AB} \bigg(\, \bigcap_{a \in A} F_{a,f(a)}\,\bigg) $ I found an interesting exercise of other amazing book (Jech's) that I'm not totally sure about how to do it.   Prove the following form of the distributive law:   $$\bigcap_{a\in A} \bigg(\, \bigcup_{b\in B} F_{a,b} \, \bigg) = \bigcup_{f\in ^AB} \bigg(\, \bigcap_{a \in A} F_{a,f(a)}\,\bigg) $$  Assuming that $F_{a,b_1} \cap F_{a,b_2} = \emptyset $ for each $a\in A$ and $b_1,b_2\in B$ and $b_1\not=b_2$.  First of all, I'm not completely sure about what $ F_{a,b}$ really means. I suppose that is  the range of a family with a domain $A \times B$.    And second, I cannot figure out how to do the converse (assuming that the first part it is correct, I used as normal in this kind of proof element chasing)  Proof:  ($\Rightarrow$) ...  ($\Leftarrow$) Suppose that $z\in \bigcup_{f\in ^AB} \big(\, \bigcap_{a \in A} F_{a,f(a)}\,\big)$; then there is $f\in \,^AB$ such that $z\in  \bigcap_{a \in A} F_{a,f(a)}\, $. Let $a \in A$ be arbitrary.   Claim 1 $\, \bigcap_{a \in A} F_{a,f(a)}\subseteq F_{a,f(a)} \subseteq \bigcup_{b\in B} F_{a,b}$.  Proof of the Claim 1:   For the first inclusion: Suppose $z\in\bigcap_{a \in A} F_{a,f(a)}$; then for each $a\in A$ we have that $z\in F_{a,f(a)}$. Then $\bigcap_{a \in A} F_{a,f(a)}\subseteq F_{a,f(a)}$.  For the second inclusion: Now suppose $z\in F_{a,f(a)}$. Clearly $f(a)\in B$ because $f\in ^AB$. Then there is some $b\in B$ such that  $z\in F_{a,b}$ and hence that $z\in \bigcup_{b\in B} F_{a,b}$. $\square$  Since $a$ was arbitrary it follows that $z\in \bigcup_{b\in B} F_{a,b}$ (by claim 1) for each $a\in A$ and hence  that $z\in \bigcap_{a\in A} \big(\, \bigcup_{b\in B} F_{a,b} \, \big)$ as desired.  I really, really would very much appreciate some help with that. Thanks in advance as usual. In Fallout 4 the Bobbleheads are back.  Once you pick them up they stay in your inventory with a weight of 0 and a value of 300. Will I need them later ? Do I lose the bonus if I sell them or drop them somewhere ? Same with the magazines.  Is there any disadvantage to selling them ? Make account merges propagate to chat How do I format my code blocks? bash chained logical operator execution order, lazy evaluation Texture is missing in Cycles? Because I am pretty new to blender I watched the tutorial  from BlenderCookie.com.  I loaded  onto a sphere but then in all views the texture is just some kind of blurry with no details. After upgrading to Ubuntu 14.04 from 12.04 I have duplicate entries in dash.    How can I get rid of them? Proof of a basic $AC_\omega$ equivalence On  it is mentioned that "...  in order to prove that every accumulation point $x$ of a set $S\subseteq \mathbf R$ is the limit of some sequence of elements of $S\setminus \{x\}$, one uses (a weak form of) the axiom of countable choice. When formulated for accumulation points of arbitrary metric spaces, the statement becomes equivalent to $AC_\omega$. ..."  I have Herrlich's paper "Choice principles in elementary topology and analysis" where in theorem 2.4. it is stated that these are indeed equivalent. Then I looked up the reference he quotes, [4], which are Bentley H.L., Herrlich H., Countable choice and pseudometric spaces which does not contain the proof and  does also not contain the proof, hence my question:   Where can I see a proof of      "if $S$ is a set in a metric space $X$ with accumulation point $s$   then there exists a sequence $s_n$ in $S$ converging to $s$"   $\implies$ $AC_\omega$   ? (the other implication is clear to me). Thanks. How Can I add HTML And CSS Into PDF I have an HTML (not XHTML) document that renders fine in Firefox 3 and IE 7.  It uses fairly basic CSS to style it and renders fine in HTML.  I'm now after a way of converting it to PDF.  I have tried:   : it had huge problems with tables.  I factored out my large nested tables and it helped (before it was just consuming up to 128M of memory then dying--thats my limit on memory in php.ini) but it makes a complete mess of tables and doesn't seem to get images.  The tables were just basic stuff with some border styles to add some lines at various points; : I actually had better luck with this.  It rendered some of the images (all the images are Google Chart URLs) and the table formatting was much better but it seemed to have some complexity problem I haven't figured out yet and kept dying with unknown node_type() errors.  Not sure where to go from here; and : this seems to work fine on basic HTML but has almost no support for CSS whatsoever so you have to do everything in HTML (I didn't realize it was still 2001 in Htmldoc-land...) so it's useless to me.   I tried a Windows app called Html2Pdf Pilot that actually did a pretty decent job but I need something that at a minimum runs on Linux and ideally runs on-demand via PHP on the Webserver.  What am I missing, or how can I resolve this issue? Looping through files with spaces in the names? I wrote the following script to diff the outputs of two directores with all the same files in them as such:  #!/bin/bash  for file in `find . -name "*.csv"`   do      echo "file = $file";      diff $file /some/other/path/$file;      read char; done   I know there are other ways to achieve this.  Curiously though, this script fails when the files have spaces in them.  How can I deal with this?  Example output of find:  ./zQuery - abc - Do Not Prompt for Date.csv Is radioactive decay spontaneous or random? When it comes to radioactive decay, what is the difference between random and spontaneous?  For example, when the count rate of a radioactive isotope is measured, the readings fluctuate. Is this a demonstration of the randomness of the process, or of its spontaneous nature? What are $x$, $y$ and $z$ if $\frac{x}{y + z} + \frac{y}{x + z} + \frac{z}{x + y} = 4$ and $x$, $y$ and $z$ are whole numbers? What are $x$, $y$ and $z$ if $$\dfrac{x}{y + z} + \dfrac{y}{x + z} + \dfrac{z}{x + y} = 4$$ and $x$, $y$ and $z$ are whole numbers?  MY ATTEMPT  Let $u = x + y + z$.  Then the equation can be rewritten as $$\dfrac{x}{u - x} + \dfrac{y}{u - y} + \dfrac{z}{u - z} = 4$$  Suppose I set $$1 = \dfrac{x}{u - x} = \dfrac{y}{u - y}$$ and $$2 = \dfrac{z}{u - z}.$$  Then I get $$x = y + z$$ $$y = x + z$$ $$z = 2(x + y),$$ so that $$z = 0 = x + y,$$ which is impossible.  Next, suppose I set $$\dfrac{4}{3} = \dfrac{x}{u - x} = \dfrac{y}{u - y} = \dfrac{z}{u - z}.$$  Then I get $$4(u - x) = 3x$$ $$4(u - y) = 3y$$ $$4(u - z) = 3z$$ so that $$12u - 4(x + y + z) = 3(x + y + z)$$ which implies that $$12u = 7(x + y + z) = 7u$$ from which it follows that $$u = 0.$$ This is, again, impossible.  Alas, here is where I get stuck.  Any hint(s) will be appreciated. Contains and Custom Label in Rule Criteria - Workflow I have a picklist field-XYZ which contains a lot of values.Lets say (A,b,c,d...z) I am trying to write a rule criteria which will execute if the picklist value is any of the following (A,b,c...p).So instead of mentioning all the values in rule criteria , i created a custom label and put the values (a,b,c,d..p) in that and wrote the following in the rule criteria :   CONTAINS(TEXT(XYZ__c) ,$Label.CustomLabel))   This is not working even is the value of the picklist is equal to the one mentioned in the Custom Label.I guess the CONTAINS function is matching the whole value of custom label with Picklist.Is there other workaround/solution for this? You can use a standard dot notation or a method call in Objective-C to access a property of an object in Objective-C.  myObject.property = YES;   or  [myObject setProperty:YES];   Is there a difference in performance (in terms of accessing the property)? Is it just a matter of preference in terms of coding style?
