For example, if there are 1500 files of size 7 GB, it needs to be archived as (7 GB/1.9 GB) 4 tar files:  log-01.tar, ..., log-04.tar but I got the error: printf: {2..} expected numeric value tar: -ML1900m: No such file or directory  What should I change here? Is there a way to do this without using create volume method in GNU tar?
I have 28,000 files of size 6.7 GB in the directory aaa/input. I need create TAR files in the directory aaa/output, such that each TAR file cannot exceed 1.9 GB, so I have to tar the 28,000 files into 4 TAR files (6.7/1.9) as Log_(current date)_01.tar Log_(current date)_02.tar ... etc.  such that each tarball is less than 1.9 GB. Is there a way to do this using a Unix script?
How to Fix:Though favicons are added, it doesn't show in Google Search SOQL query for Multiselect picklist Highlight text in code listing while also keeping syntax highlighting I’m using the listings package for code listings. Now I try to highlight some part of the code using \hl from the soul package.  Here’s an example of a resulting query where the injected part of a SQL injection should be highlighted:  \begin{lstlisting}[escapechar=@,language=SQL] SELECT name, password FROM users WHERE name='@\hl{' UNION SELECT "10", 1 \#}@'; \end{lstlisting}   But inside the highlighted part the SQL syntax highlighting is not applied.  So I tried to use \lstlinline for the code part inside \hl as well but it didn’t work:  \begin{lstlisting}[escapechar=@,language=SQL] SELECT name, password FROM users WHERE name='@\hl{\lstinline[language=SQL]$' UNION SELECT "10", 1 #$}@'; \end{lstlisting}   Although this \lstinline part works outside the lstlisting block, it doesn’t work inside it. The error I get for that particular line is:     Extra }, or forgotten \endgroup.   Maybe I’m just missing just some special syntax to get this working. Or is it not possible at all to get proper syntax highlighting for the \hl-highlighted part as well? How to read dash files Why are these estimates to the German tank problem different? Suppose that I observe $k=4$ tanks with serial numbers $2,6,7,14$.   What is the best estimate for the total number of tanks $n$?   I assume the observations are drawn from a discrete uniform distribution with the interval $[1,n]$. I know that for a $[0,1]$ interval the expected maximum draw $m$ for $k$ draws is  $1 - (1/(1+k))$. So I estimate $\frac {k}{k+1}$$(n-1)≈$ $m$, rearranged so $n≈$ $\frac {k+1 }{k}$$m+1$.  But the frequentist estimate from  is defined as:  $n ≈ m-1 + $$\frac {m}{k}$  I suspect there is some flaw in the way I have extrapolated from one interval to another, but I would welcome an explanation of why I have gone wrong! CUDA writing to constant memory wrong value I want to write all zeros to my hard drive, so I can re-install windows 7 Why rationalize the denominator? In grade school we learn to rationalize denominators of fractions when possible. We are taught that $\frac{\sqrt{2}}{2}$ is simpler than $\frac{1}{\sqrt{2}}$.  says that "there is a bias against roots in the denominator of a fraction". But such fractions are well-defined and I'm failing to see anything wrong with $\frac{1}{\sqrt{2}}$ - in fact, IMO it is simpler than $\frac{\sqrt{2}}{2}$ because 1 is simpler than 2 (or similarly, because the former can trivially be rewritten without a fraction).  So why does this bias against roots in the denominator exist and what is its justification? The only reason I can think of is that the bias is a relic of a time before the reals were understood well enough for mathematicians to be comfortable dividing by irrationals, but I have been unable to find a source to corroborate or contradict this guess. $\Bbb{Z}_{26} \rtimes_{\alpha} \Bbb{Z}_{5} \cong \Bbb{Z}_{26} \times \Bbb{Z}_{5}$ as groups. Class object affecting other class object when thread.sleep- Python Removal of statistically significant intercept term increases $R^2$ in linear model In a simple linear model with a single explanatory variable,  $\alpha_i = \beta_0 + \beta_1 \delta_i + \epsilon_i$  I find that removing the intercept term improves the fit greatly (value of $R^2$ goes from 0.3 to 0.9). However, the intercept term appears to be statistically significant.

Also it's just such an irritating problem that I'd give all my rep away if I could to the clever person who has the answer. It would be nice to have a few minutes after creating the bounty to be able to raise it. But for now could a mod or something please raise it for me to 500. Is a strong background in maths a total requisite for ML? I'm starting to want to advance my own skillset and I've always been fascinated by machine learning. However, six years ago instead of pursuing this I decided to take a completely unrelated degree to computer science.   I have been developing software and applications for about 8-10 years now, so I have a good handle but I just can't seem to penetrate the maths side of machine learning/probabilities/statistics.   I start looking at learning material and on the first page it might include something which confuses me and immediately sets up a barrier in my learning.   Is a strong background in maths a total requisite for ML? Should I try and fill in the blanks of my maths before continuing with ML? Can self learning really work for just a developer without any hard computer science background?
