Is it possible to use bibtex (or maybe some other package) to produce the bibliography (from a bib file) in form of a table? For instance, having authors names in one column, titles in the other, and so on?
I need to customize my references in the following style using biblatexs Alpha style having the columns Label, Author, and Title and Other Information.    Till now with your help I could already change the square brackets to slashes.   My code so far is:   \documentclass[12pt]{scrartcl}  .  .   \usepackage[% natbib        = true, backend       = bibtex8, %bibtex, biber style         = alphabetic, %citestyle     = alphabetic, maxcitenames  = 2, mincitenames  = 1, %bibstyle      = alphabetic, %authoryear, %draft, %, sorting       = nyvt, maxbibnames   = 6, minbibnames   = 6, language      = ngerman, date          = long, backref       = false, backrefstyle  = none,  % none, three, two, two+, three+, all+ firstinits=true  ]{biblatex}    \usepackage[babel,german=quotes]{csquotes}    \bibliography{input/literatur}      \newrobustcmd{\mkbibslashes}[1]{/#1/}      \DeclareFieldFormat{labelalphawidth}{\mkbibslashes{#1}}    \DeclareFieldFormat{shorthandwidth}{\mkbibslashes{#1}}     \DeclareCiteCommand{\cite}[\mkbibslashes]    {\usebibmacro{prenote}}    {\usebibmacro{citeindex}% \usebibmacro{cite}}    {\multicitedelim}    {\usebibmacro{postnote}}    \renewcaptionname{ngerman}{\refname}{Literaturverzeichnis}   .   .   .   Thanks again
PHP & MySQL: mysqli_num_rows() expects parameter 1 to be mysqli_result, boolean given Compile Views in ASP.NET MVC In the current era of cricket, we see batsmen using switch hits to play a ball. That is, while playing a ball they change their batting side (left to right handed and vice versa) just before the ball comes to them.  My question is, can a bowler bowl a switch ball? Meaning, can a left hand bowler bowl right handed to a batsman? If it is not permitted, then is it not unfair to the bowlers that batsmen can change their batting style but not the bowlers? Or are there are any rules against a switch hit? Interpreting exp(B) in multinomial logistic regression This is somewhat of a beginner's question, but how does one interpret an exp(B) result of 6.012 in a multinomial logistic regression model?  1) is it 6.012-1.0 = 5.012 = 5012% increase in risk?  or  2) 6.012/(1+6.012) = 0.857 = 85.7% increase in risk?  In case both alternatives are incorrect, can someone please mention the correct way?  Ive searched many resources on the internet and I get to these two alternatives, and I am not entirely sure which one is correct. How to choose input method on Kubuntu 18.04? Recently I began studying machine learning, however I failed to grasp the intuition behind .   The following are the facts about logistic regression that I understand.   As the basis for hypothesis we use . I do understand why it's a correct choice, however why it's the only choice I don't understand. Hypothesis represents the probability that the appropriate output is $1$, therefore the domain of our function should be $[0,1]$, this is the only property of sigmoid function I found useful and appropriate here, however many functions satisfy this property. In addition, sigmoid function has a derivative in this form $f(x)(1-f(x))$, but I don't see the utility of this special form in logistic regression.   Question: what so special about sigmoid function, and why we cannot use any other function with domain $[0,1]$? The cost function consists of two parameters ${\rm Cost}(h_{\theta}(x),y)=-\log(h_{\theta}(x))$ if $y=1, {\rm Cost}(h_{\theta}(x),y)=-\log(1-h_{\theta}(x))$ if $y=0$. In the same was as above, I do understand why it's correct, however why is it the only form? For example, why couldn't $|h_{\theta(x)}-y|$ be a good choice for the cost function?  Question: what is so special about the above form of cost function; why cannot we use another form?   I would appreciate if you could share your understanding of logistic regression. Book ID: Astronauts and Lab Students can create portals through space Desperate to locate and re-read exceptional book/series, but cannot remember the title. The high concept: The U.S. has just sent the first successful expedition to Mars, and it has just landed. As the astronauts make their initial exploration outside their ship, a tear in the fabric of space opens up right in front of them, and they look through to the insides of a laboratory (at a California university?) and two students who just figured out how to create arbitrary portals between two points in the Universe. The rest of the novel/series is a consequence of this breakthrough. But I can't remember the author and title(s). Surely someone reading this forum will remember it well! TIA.  (Reposted .) Using the Terminal keybindings with bash on macOS I have been trying to learn the keyboard shortcuts for the shell on macOS, but when I tried using ALT+B, it did not work.

Setting git default flags on commands My web application generates a lot of reports in formats like excel sheet, Csv(comma-separated values), fixed width columns, pdf format, html reports etc based on the parameters I select. There is a lot of data in the reports.  Are there any essential criteria for testing report generation that I may not have considered.  I know to test these things:   Data is correct Filters are used Output format is correct   What else is there? How do I install pillow in Ubuntu 16.04 LTS? Random errors on various sites when viewing main page Occasionally (very occasionally) when returning to the main page of a site by clicking on the logo I get the following message:     It was not possible to perform this tag search at this time due to an unexpected error.   This is odd because I'm not performing a tag search.  So far this has happened on both Movies &amp; TV and Cooking.  I have heard that others are getting this same message. Best way to migrate a huge SQL Server database with low downtime over network Problem definition  Our database server needs to be transferred to an other datacenter. It runs on Microsoft SQL Server 2012 Enterprise (64-bit) and contains two databases of about 2TB and 1TB.  Having little to no downtime for this would be ideal.  Workload  Those databases are used for a .NET website and are constantly getting updated.   Having it not available over the weekend would be acceptable though. The currently in use DB would remain the only one in use until the switch over to the new one.  That switch would ideally be made just by changing DNS entries to point to the new DB server while making sure the DB is not being updated.  Also, time taken by this operation does not really matter as long as the switch from one server to the other (downtime) is kept low.  Approaches considered   Backup and restore  This has been done in the past but involved a high downtime even though it was done through an internal network, so more efficiently than through Internet Log shipping  As far as I understand, this approach would minimize downtime by configuring a master/slave and transferring  an exact copy of the master DB to its slave being read only. As mentioned above, no access to the slave would be necessary and we just need a way to have a replica of the master DB without data corruption.   It also seems to be quite efficient in terms of resources utilization and wouldn't impact to much the master performance.   I might be wrong about this approach so feel free to correct me. Database mirroring  I'm not too aware of that approach but it seems like a valid option. No need to have real time sync and performance of the master is quite important so asynchronous would be the way to go if this approach were to be chosen. Other options?  That server runs directly on bare metal hardware so lower level solutions are unfortunately not an option. Maybe there is a better way to get this done?   Constraints  As described, those databases are quite big to the point they are hard to maintain but that's an other problem.  The versions of SQL Server will be the same (Microsoft SQL Server 2012 Enterprise 64-bit).  It will have to be transferred over network between two datacenters so most probably over Internet. Having disks sent from one site to the other for an initial sync is unfortunately not an option. Having some sort of security for the transfer would be ideal but we will do the best of this situation.  That should give a quite good overview of our needs for this task and hopefully some of you had to face that situation before. I've been wondering what makes the  such an important model. What I came up with:   It is a (relatively) simple system, making it a perfect example for physics students to learn principles of classical and quantum mechanics. The harmonic oscillator potential can be used as a model to approximate many physical phenomena quite well.   The first point is sort of meaningless though, I think the real reason is my second point. I'm looking for some materials to read about the different applications of the HO in different areas of physics. GeoReference tiff image into the Google map? I want to Geo-reference a tiff image contain a Map for a specific region, I need to add this region(image) and Geo-reference it on the Google map, SO I can see on the map for the region I select the image which I have inserted.  the image also need information such as the Latitude and Longitude of corners and size, and the pixel per meter measurement.  How to do the correct Geo-reference for that ? Proof that the coefficients in an OLS model follow a t-distribution with (n-k) degrees of freedom Background  Suppose we have an Ordinary Least Squares model where we have $k$ coefficients in our regression model, $$\mathbf{y}=\mathbf{X}\mathbf{\beta} + \mathbf{\epsilon}$$  where $\mathbf{\beta}$ is an $(k\times1)$ vector of coefficients, $\mathbf{X}$ is the design matrix defined by  $$\mathbf{X} = \begin{pmatrix} 1 &amp; x_{11} &amp; x_{12} &amp; \dots &amp; x_{1\;(k-1)} \\ 1 &amp; x_{21} &amp; \dots  &amp;       &amp;   \vdots \\ \vdots &amp;   &amp; \ddots &amp;       &amp;   \vdots \\ 1 &amp; x_{n1} &amp; \dots  &amp; \dots &amp;   x_{n\;(k-1)}     \end{pmatrix}$$ and the errors are IID normal,  $$\mathbf{\epsilon} \sim \mathcal{N}\left(\mathbf{0},\sigma^2 \mathbf{I}\right) \;.$$  We minimize the sum-of-squared-errors by setting our estimates for $\mathbf{\beta}$ to be $$\mathbf{\hat{\beta}}= (\mathbf{X^T X})^{-1}\mathbf{X}^T \mathbf{y}\;. $$   An unbiased estimator of $\sigma^2$ is  $$s^2 = \frac{\left\Vert \mathbf{y}-\mathbf{\hat{y}}\right\Vert ^2}{n-p}$$ where $\mathbf{\hat{y}} \equiv \mathbf{X} \mathbf{\hat{\beta}}$ ().   The covariance of $\mathbf{\hat{\beta}}$ is given by $$\operatorname{Cov}\left(\mathbf{\hat{\beta}}\right) = \sigma^2 \mathbf{C}$$ where $\mathbf{C}\equiv(\mathbf{X}^T\mathbf{X})^{-1}$ () .  Question  How can I prove that for $\hat\beta_i$, $$\frac{\hat{\beta}_i - \beta_i} {s_{\hat{\beta}_i}} \sim t_{n-k}$$ where $t_{n-k}$ is a t-distribution with $(n-k)$ degrees of freedom, and the standard error of $\hat{\beta}_i$ is estimated by $s_{\hat{\beta}_i} = s\sqrt{c_{ii}}$.    My attempts  I know that for $n$ random variables sampled from $x\sim\mathcal{N}\left(\mu, \sigma^2\right)$, you can show that  $$\frac{\bar{x}-\mu}{s/\sqrt{n}} \sim t_{n-1} $$ by rewriting the LHS as $$\frac{ \left(\frac{\bar x - \mu}{\sigma/\sqrt{n}}\right)  }   {\sqrt{s^2/\sigma^2}}$$ and realizing that the numertor is a standard normal distribution, and the denominator is square root of a Chi-square distribution with df=(n-1) and divided by (n-1) ().  And therefore it follows a t-distribution with df=(n-1) ().  I was unable to extend this proof to my question...  Any ideas?  I'm aware of , but they don't explicitly prove it, they just give a rule of thumb, saying "each predictor costs you a degree of freedom".
