I have a script which calls two commands:  long_running_command | print_progress   The long_running_command prints progress but I'm unhappy with it. I'm using print_progress to make it nicer (namely, I print the progress in a single line).  The problem: Connection a pipe to stdout also activates a 4K buffer, so the nice print program gets nothing ... nothing ... nothing ... a whole lot ... :)  How can I disable the 4K buffer for the long_running_command (no, I do not have the source)?
I've read  about how some publishers (e.g., Springer) allows authors to submit to arXiv before journal submission, but they make authors wait for a year after acceptance to submit to arXiv.   My question is: Is it okay to submit to arXiv during the time when the paper is under consideration by the journal, for example after it has been "revised and resubmitted" but before final decision?

Detection of the Electric Charge of a Black Hole Is there a cross-browser onload event when clicking the back button? I am an Indian living in Italy and I am going to the UK for a leisurely family vacation for about 10 days. Please note, this application is not very straight forward. There are four applicants, one applicant is applying from India another two are applying from Singapore and I am applying from Italy. The checklist at the top has the statement  all documents must be in English translated documents must be certified  I got the proof of accommodation from my commune, but it is in Italian. Getting it translated, isn't such a big deal as the commune itself provides multi-lingual certificates. For the rest of the documents, this is an issue. Such as for &quot;Evidence of being in education&quot;, my university provides an online certificate for this purpose which is in Italian. Multiple acquaintances said that they provided their Italian house contract (in Italian) as proof of residency and no requirement came up for translation. Can anyone comment on how strict are they while enforcing the translational requirements of documents in respect to a short term visitor visa? Distribution of linear combination of OLS regression coefficients I have a simple linear OLS regression $Y_i = \alpha+ \beta_1 X_{1i} + \beta_2 X_{2i} + e_i$ where $e_i \sim N(0,\sigma)$. I have estimated the regression from the data and obtained estimates for my coefficients as well as the corresponding covariance matrix. Assume my dataset is large (>500)  Now I would like to construct the 95% confidence interval for $Z = a_1 \beta_1 + a_2 \beta_2$. My first thought was that I could assume that Z follows a normal distribution because my regression coefficients are approximately normal and a linear combination of normal variables is also a normal variable. I do find some sources where they treat $Z$ as a normal random variable.  But now I am in doubt because I found that a linear combination of normal random variables is only normal if they are independent. So is it still save to assume $Z$ is random? How can I reset or revert a file to a specific revision? How to put a full-width table at the top or bottom of the same two-column page as the reference text? I'm posting today because I would like to reduce white space in a document I'm writing. The content is two-columns but I have floating tables that span across both columns (table*).   At some point, the text ends in the beginning of the first column of a new page. I would like to include my table on this page since it has a lot of free space below the text, but when I insert the table* right after the text, it goes to the top of the next page instead:    Do you know a way of obtaining the desired behavior?

Some like to print the material, so I created a handout. Some students prefer to have 2,3,4,6 etc. pages per sheet of A4 paper. How can I go about to automatize the following code, so that it outputs 4 different files in 1x2,1x3,2x2,2x3 format?  I'd like to avoid having to compile it again everytime for the different formats.  \documentclass[a4paper]{article} \usepackage{pdfpages}  \begin{document} \includepdf[pages=1-last,nup=1x2,landscape=false,frame=true,             noautoscale=false,scale=1,delta=0mm 5mm]{Pres7Chap13-Handout.pdf} \end{document} Can you help me resolve this paradox for a geodesic orbit?

Is it possible to edit a layer in QGIS while there is an active query? I am new to Quantum and I am digitizing polygon layers using the editing features. I would like to apply simple queries ('date > 2012/08/01'), however while the query is active I cannot edit the layer. Is this possible? I have a Dell Inspiron 1525 laptop and I am planning on purchasing a mac mini, new version , I am tight on money for a while and want to use my current laptop screen as monitor for mac mini, I just want to know if it is at all possible to do, I have windows 7 and ubuntu 11.04 installed in my laptop, and I don't really care if need to wipe them out, or purchasing a monitos is the only option left, also I am planning to use it for coding and stuff, so VNC is probably not a good choice. What is the best way to unit test a method that calls into multiple methods, for example:  modify(string value) {     if(value.Length &gt; 5)  replaceit(value);      else changeit(value); }   This pseudo code has a modify method that (currently) calls either replaceit() or changeit(). I have already wrote tests for replaceit and changeit, so writing a new test for modify will be 99% the same set of code.  I need to test it thought because it may change in the future.    So do I copy paste the existing test code?  Move the test code to a common function?  Any other ideas?  I'm not sure of the best practice here. Graphics file extensions and their order of inclusion when not specified When using 's \includegraphics you can specify the file extension or not. For generic use and perhaps portability, extensions are commonly dropped. The types of "approved" inclusions and their order of precedence depends on the driver/compiler being used. What are these driver-defaults?  Related: How to reduce space between image and its caption?
