I submitted a paper for a conference. While the paper got submitted for publication in the proceedings, the feedback seemed quite negative. The main criticism was that the model I have designed uses too many simplifications.  I am giving a presentation at the conference in about a week and a half. Since I submitted the original paper I have achieved a significant amount, and have been able to improve my model and deal with a number of the simplifications.  My question is: for the presentation content, do I have to stick with the work that is going to be published, or can I also present some of the more interesting, newer work?  For reference, my field is engineering (renewable energy)
I am presenting a paper at a computer science conference.  The paper I submitted to the conference mentioned future work that would significantly enhance the utility of the method.  This work was work that was always planned to be part of the same "project" as the work in the paper, indeed the conference paper is presented as a part way step towards doing X, and the future work is what takes it all the way.  The extension was quite involved (and not quite complete when I submitted the paper for review). They day before I left for the conference that work was "completed", in that a journal article about it was submitted for review.  Now when I present at the conference, in the conclusion I want to mention the future work&nbsp;&ndash; at least to the extent that it was described in the conference paper. Should I go into more detail? Should I even mention that "This work is now complete, and is under review for publication"?
Problem with pstricks and htlatex/tex4ht Consider the following MWE:  \documentclass{article} \usepackage{pst-all}  \begin{document}   \begin{pspicture}(0,-3)(12,5)       \psline[linewidth=2pt]{-&gt;}(1.5,0)(0,0)   \end{pspicture} \end{document}   This compiles fine with latex (not with pdflatex) but when run with htlatex it leads to the ghostscript error:  System call: dvips -E -q -Ppdf -f q.idv -pp 2 &gt; zzq.ps System return: 0 System call: gs -sDEVICE=pngalpha -sOutputFile=q0x.png -r110x110 -dEPSCrop -dBackgroundColor=16#ffffff -dTextAlphaBits=2 -dGraphicsAlphaBits=2 -q -dbatch -dNOPAUSE zzq.ps -c quit Error: /configurationerror in --setpagedevice-- Additional information: [/PageSize [0 0]] Operand stack:    --nostringval--   (%%BoundingBox: 72 72 72 72)   --dict:1/2(ro)(G)--   --nostringval--   --nostringval--   (%%BoundingBox: 72 72 72 72)   1   72   72   false   --dict:1/1(L)-- Execution stack:    %interp_exit   .runexec2   --nostringval--   --nostringval--   --nostringval--   2   %stopped_push   --nostringval--   --nostringval--   --nostringval--   false   1   %stopped_push   1951   1   3   %oparray_pop   1950   1   3   %oparray_pop   --nostringval--   1934   1   3   %oparray_pop   1820   1   3   %oparray_pop   --nostringval--   %errorexec_pop   .runexec2   --nostringval--   --nostringval--   --nostringval--   2   %stopped_push   --nostringval--   %ztokenexec_continue   (scanner state)   --nostringval--   --nostringval--   --nostringval--   --nostringval--   --nostringval--   --nostringval--   1913   10   3   %oparray_pop   --nostringval--   --nostringval--   --dict:1/10(L)--   --nostringval--   15   %dict_continue Dictionary stack:    --dict:1190/1684(ro)(G)--   --dict:0/20(G)--   --dict:82/200(L)-- Current allocation mode is local Last OS error: Invalid argument Current file position is 169 GPL Ghostscript 9.16: Unrecoverable error, exit code 1 --- Warning --- System return: 256 Entering q.css Entering q.tmp   This code used to work fine. From other examples I suspect that the problem has something to do with dvips having trouble determining the bounding box for the image (compare with  -- although the solution given here, of using separate files for each image, is not a viable solution for me), but I have not been able to work out what the problem is.  Does anyone have any ideas? Powerset of set with empty sets I am working on a problem with the following set:  $$S =  \{\varnothing,\{\varnothing\}\}$$  My solution was: $P(S) = \{\varnothing, \{\varnothing\},\{ \varnothing , \{ \varnothing \}\}\}$, but the solution on the textbook shows: $P(S) = \{ \varnothing , \{ \varnothing \}, \{\{\varnothing\}\}, \{ \varnothing , \{ \varnothing \}\}$  Where does the $\{\{\varnothing\}\}$ come from?  Thanks Let $a,b$ be positive integers.  When $$k = \frac{a^2 + b^2}{ab+1}$$ is an integer, it is a square.    Proof 1: (Ngô Bảo Châu): Rearrange to get $a^2-akb+b^2-k=0$, as a quadratic in $a$ this has two values: $a$ and $kb - a = (b^2-k)/a$. (The second root is determined in two different ways from the expansion $(x-r_1)(x-r_2) = x^2 - (r_1 + r_2)x + r_1 r_2$.)  Now suppose we have $a,b$ such that $k$ is an integer but not a square, by the investigation about roots we have that the second root is a nonzero integer since $k,b,a$ are integers and $k \not = b^2$, futhermore it is positive which is easily seen from its defining equation.  WLOG assume $a \ge b$ so that the second root is strictly smaller than $a$. This leads to a decent, replacing $a$ with the second root.    Proof 2 (Don Zagier): Apply reduction theory (specifically, Sätze 1 and 2 of Section 13 of my book on quadratic fields) to the quadratic form $x^2 + kxy + y^2$, which is the unique reduced quadratic form in its equivalence class.    Note that Proof 2 is pretty much the same as Proof 1 when written out in explicit detail, but I could not read Zagier's book because I cannot read German.  I would like to know more approaches to this and other alternative proofs of this result if possible! Thanks in advance.  I would also be interested in related problems (especially easier ones of a similar nature) and texts which cover the reduction theory in English. Why do first order languages have at most countably many symbols? Every proof that I read seems to assume that $|L|\leq\aleph_0$. But then how do you model things like field over $\mathbb{R}$ without running out of variable symbols?  More importantly, how can I prove that $|L|\leq\aleph_0$? Why didn't anybody Summon the Triwizard cup in the maze? Can I use Wubi for manual installation? Is it possible to use Wubi for Ubuntu 13.04?

True or false: {{∅}} ⊂ {∅,{∅}} How much did the Trade Federation know about their 'lord' at time of blockade? revoking apex managed sharing permission I'm using apex managed sharing to grant permissions very similar to how it is done in this example trigger:   However, I also need the ability to revoke or delete this access and having it revert to private. The reason for this is my understanding is that there are only two access options for managed sharing access 'read' or 'edit' with no 3rd option of 'none' or 'private'.  Reference:   I've tried adding the shares to a list and deleting the list and I'm getting the error: DELETE_FAILED, cannot delete owner or rule share rows,   I also noticed there is a field on the share object 'isDeleted' this field however is not writable.  Does anyone have experience revoking or deleting these permissions once they've been created?  Thanks! How to change the date format? Presently the date is showing as mmm dd hh:mm:ss. Is there any way that I can change it to as per my liking. For example : dd mmm, hh:mm:ss. As human beings, we observe the world in which we live in three dimensions. However, it is certainly theoretically possible that more dimensions exist.  Is there any direct or indirect evidence supporting a fourth dimension? Importance of series resistor at output of Rectifier Why do we tag questions? My question—my meta-question as the case may be—concerns the purpose of these words referred to as "tags". Let me be clear: I use tags. The site supports them, so why shouldn't I? My understanding of their reason for existing is tragically incomplete.   Are they used for searching? Are they useful in any other way, or do they merely act as decoration?     For more information, see "" and "" in the . PlotRange precision limit?

I have some spinning smbd  processes that I caused from my windows machine and so I telnetted into the linux server and I want to kill those spinning processes.   I don't have authority to restart services or reboot the machine. I am wondering whether there is a bulletproof way to know if one is successful in decrypting a file.   As an example, say I encrypt a text file and protect it with a 3 letter password. I use brute force to decrypt it, but two different passwords lead to a file that contains English intelligible text. Is there a way for me to know which one is the original one? In other words, is there an infallible way to know I've entered the password correctly? Sponsor Gallery, Page, or Something Like That?
