First of all, apologises for the noob question. Second, I am aware similar questions have been asked but their solutions don't work for me unfortunately. Hopefully someone here can point me in the right direction.   I have a table (markup below), which is rendered very tightly together, which is proving cramped and difficult to read on the document. How can I increase the column width explicitly?  \begin{table}[h] \centering \label{my-label} \begin{tabular}{@{}llll@{}} \toprule {\bf } &amp; {\bf Classifier 1} &amp; {\bf Classifier 2} &amp; {\bf Classifier 3} \\ \midrule {\bf F1-Score} &amp; \multicolumn{1}{c}{71.75\%} &amp; \multicolumn{1}{c}{74.30\%} &amp; \multicolumn{1}{c}{77.86\%} \\ \bottomrule \end{tabular} \end{table}
I notice that the space between each column of a table in LaTeX is not quite wide (at least for me). Is there any way to set this? I found the \hspace, but I don't get how to use this in the table.
What happens when I terminate a process and the socket send buffer is not empty? In Windows (and probably in other operating systems), if a process has a TCP connection with another process on another machine, and then I terminate the process, an RST packet will be sent to the other machine to indicate the end of the connection.  Now imagine that when the process is terminated, there were still some data left in the send buffer. What will happen in this case, will these remaining data be sent to the other machine followed by an RST packet, or will these remaining data be ignored and only an RST packet is sent?

Show that is an equivalence relation.  Equivalence relation means it satisfies reflexity, symmetry, and transitivity.  reflexive: $x\sim x$ means 5 divides $x$  symmetry: $x \sim y \rightarrow y\sim x$ means 5 divides $x - y$ and 5 divides $y - x$: $$5/(x - y) = 5/(y - x)$$ so symmetry is satisfied.  I am not sure if I am right here and I am lost on how to prove it is transitive any suggestions would be greatly appreciated I've been trying to develop an intuition based understanding of Bayes' theorem in terms of the prior, posterior, likelihood and marginal probability. For that I use the following equation: $$P(B|A) = \frac{P(A|B)P(B)}{P(A)}$$ where $A$ represents a hypothesis or belief and $B$ represents data or evidence. I've understood the concept of the posterior - it's a unifying entity that combines the prior belief and the likelihood of an event. What I don't understand is what does the likelihood signify? And why is the marginal probability in the denominator? After reviewing a couple of resources I came across this quote:     The likelihood is the weight of event $B$ given by the occurrence of $A$ ... $P(B|A)$ is the posterior probability of event $B$ , given that event $A$ has occurred.   The above 2 statements seem identical to me, just written in different ways. Can anyone please explain the difference between the two? Partial Sums of Geometric Series How to set the default value of an exposed filter rather than -Any-?

I'm having a hard time understanding the real distinction between  and .  accumulative     adjective         tending to accumulate or arising from accumulation; cumulative.   tending to accumulate wealth; acquisitive.      cumulative     adjective         increasing or growing by accumulation or successive additions: the cumulative effect of one rejection after another.   formed by or resulting from accumulation or the addition of successive parts or elements.   of or pertaining to interest or dividends that, if not paid when due, become a prior claim for payment in the future: cumulative preferred stocks.      These definitions (and those from other dictionaries as well) say different things but I can't understand how they aren't really meaning the same thing.  Yet, when thinking about it, it seems there are some cases where it is distinctly more correct to use one or the other.  What's the difference, practically? I have to import large Shapefiles (> 1 million records) into PostGIS, and I have been wondering about the best way to do it.    In my question I used the word "hack", instead of tool, on purpose because I think this is not so much a matter of which tool, but which set of steps, or configuration settings to use. So far, I have tried the  plugin (QGIS), the  Postgis tool and the GDAL  tool. You can view my full review on  post. So far, I find all of them really unresponsive, when dealing with a large dataset. I was wondering if someone experienced a similar issue, and if you could share something about the approach. Can we see emission lines in stars? I read that stars show both absorption and emission lines. While how we see absorption lines is clear to me, I don't understand how (and when) we see the emission lines. Based on what I read in several of your threads such as  we should not be seeing emission lines at all, since all the emissions would come from the hotter interior but those can't reach the outside (unless I misunderstood this point), and the only emission we see is blackbody radiation. But then how do we see the few emission lines such as in the spectrum shown ? CSV text files loading error / crash in QGIS 2.18.8 I got a problem when I try to load tab-separated text files in the "Create a layer from the delimited text file" tab (that one with de comma symbol). After normally selecting the X and Y fields and clicking OK, the reference coordinate system (SRC) selector screen appears, then the program closes by itself. I had uploaded more than a hundred of this type of file by the same procedure in the previous version of QGIS (2.14 Essen) and have no problem, but since I updated to version 2.18.8 (Las Palmas) I can not load any files or .CSV type.
