Cant access NFS share with non-root user
how to get user permissions for nfs share?
Doing bad in undergraduate but good in a masters program How do I identify SMD components? (or how do I identify any component) How do I identify the markings on an SMT component and match it up with a part number so I can be a good designer and actually look at a datasheet (and read the whole thing)? Or identify a part to replace an unknown part on a PCB? I am kind of confused on the terminology of &quot;space&quot;. From  I am getting that  In mathematics, a space is a set (sometimes called a universe) with some added structure.  And from topological and metric spaces, I know that we a space is a a tuple of a set and a structure, e.g. $(X, \tau)$, $(X, d)$, where $\tau$ and $d$ are a topology and a metric respectively. On the other hand, in machine learning the term &quot;features space&quot; is used a lot for sets like $\mathbb R^n$, e.g.  and although it often refers to the set underlaying set itself, not the tuple of set plus the added structure. In fact, I have done the same in a previous publication (which the peer-reviewers accepted), but I would like to be both correct and precise in what I research, write, and submit. Is it just that machine learning researchers are imprecise in their terminology? Is it just an ? I think, what some people are doing, might be they consider a space to be a set, which is somewhat structured, instead considering the set with the structure (so, the tuple), to be the space.  I am not sure how to think about this. How do I deal with this in my writing? Especially since, what happens a lot is that I need subsets and element out of the underlying sets of all kinds of spaces.  Of course it would greatly help if there was a general name for a set that is the underlying set of a space, , but it seems that there is no dedicated name for such a set. Let's say there was a features space $(X, \cdot)$, (where I am not even sure, what structure we would add). Then it would be great to have a name for the set, let's call it an asdf. So we could say the feature asdf.  Afterthoughts: What makes it worse for me is that it seems ( and ) I am not even using the word &quot;structure&quot;, right, since it is about operations, so we are talking about an &quot;algebraic structure&quot;, while &quot;geometric space&quot; is... something else...? So apparently a &quot;vector space&quot; is actually not a &quot;geometric space&quot;, but an &quot;algebraic structure&quot;. I can understand that point, but the language gets even more confusing. I have this value    How to read that in English? translating from my native language, I would say     Ten base of nine.   but is that really correct? Combine rows / concatenate rows Blank white desktop icons on new Windows 7 install I just did a fresh install of Windows 7 professional on my father's Toshiba Satellite laptop and everything went smoothly except for the fact that certain desktop shortcuts appear as a blank white page.    I've tried:    going in and changing the icon to many different things reloading the icon cache by deleting the IconCache.db file uninstalling his Free AVG as he heard the virus scanner might be preventing it (it wasn't and he put it back.)   The one thing these icons have in common is that they are shortcuts to some very old DOS executables.  One of them is Word Star 2000 to give you an idea.  Does anybody have any other suggestions besides what we've tried? Truncated 200GB table but disk space not released If you have two envelopes, and ...

Kernel Panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0) Upon trying to upgrade from 10.10 to 11.04 all seemed to go well until the restart. This error message is what comes up:  Kernel Panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)   How do we fix that? If time standard clocks and any memories about the time standard are destroyed, can we recover the time standard again? Assume the time standard clocks and any memories about the time standard are destroyed. Can we recover the time standard again exactly?  Recovering the time standard again means we can determine the date  and time that are exactly the same as the destroyed time standard clocks will show (if they are not destroyed). How often should I remove the charger from my rMBP? I want my battery to remain healthy. I used to charge it full then remove the charger after it's done, then put it back on when it goes down to 10% ..

Here's a picture below. A book with two twins and a difficult relation, a room where time flows slower than the outside and a mysterious monster coming from a sink There was this pocket book, back when I was a teenager (20 years ago), with these two twins discovering a room (it was something like a tool shed) where time flowed slower (1 hour inside was equal to 1 minute outside if i remember correctly).   Inside the shed there was a sink and a strange snake-ish metallic monster was slowly coming out from it.  One of the twins, the one with the "less marked" personality, decides to spend one year (during a whole night) inside the room in order to get out older than his twin.  I don't remember what happens with the monster, I think they destroyed the whole shed in the very end. Lasso and statistical signficance of selected variables Just beginning with photography.    Consider this image:     (This photo was taken by Harold "Doc" Edgerton in 1964 using his Rapatronic camera.)  I am looking for a  camera that can capture such an image. I am not looking for more fps. less fps is fine, but it must be able to capture such an instance.   What features should I look in such a camera?  How fast should be the shutter speed? What other things I should look for? Detecting Color of iPhone/iPad/iPod touch?
