There are some mathematicians who are active online and who blog about their work at various stages, including when they upload a paper to the arXiv. I like this aspect as it gives a chance for the author to give a more informal explanation as to how the results were arrived at or how to interpret them. However, I've seen a few times they they say, on their blog or in the arXiv comments, that the paper is submitted for publication (which is perfectly fine), but additionally specify exactly which journal it has gone to.   As these mathematicians are in fact well-respected and solid in their career I do not wish to impugn their decision, but it smacks of me of being rather confident that the journal will accept the paper, after some small revisions. Since the refereeing process in mathematics takes months, at a minimum, and up to a couple of years in more involved cases, the statement that the submission is to a particular journal will stand for a long time before we know either way as to the result.  As a early career researcher I wouldn't presume to proclaim the journal I think my work should be published in. But am I selling myself short? Let us say I am reasonably confident the paper I am submitting is a good fit for the chosen journal, should I also stake my claim during the preprint phase, to signal at least how "good" I think my paper is? (which judgement people can then assess based on their own experience)  Edit: I see the answers at the previous similar question, while acknowledging the practice to be field-dependent generally warn against this behaviour. However I am observing a career-stage-dependent behaviour in my field contrary to those good suggestions, weighted towards those who already have some advantage (to borrow from Dan Romik's example, imagine Bob could always carry through on his promise, never overstepping the bound on what had actually been done).
Many researchers list out their submitted manuscripts on their website. Some specify the journal name, like     Smith J, Oliver J (under review) My awesome paper. Nature.   while others don't, like     Smith J, Oliver J (under review) My awesome paper.   One reason I can think of as to why some don't mention the journal name is that they may get embarrassed in the case where the current journal rejects the paper. Then, the "circle" will know this paper gets rejected from Nature first and then ends up in an inferior journal.  Besides this, are there any other considerations preventing people from mentioning to which journal they submit a paper to?  P.S.: I am asking because my advisor is a researcher who only mentions accepted  papers on his webpage. As a student hunting jobs, I feel it is advantageous for me to mention my submitted papers on my webpage. I hesitate to do so, as I worry I may make my advisor unhappy by announcing in which journal our papers are currently under review.
I've got a repo that I contribute to within an Organization that I administer. I'm trying to add it to careers, but it won't allow it. Is this on purpose? I don't really want to fork it to my personal account, since I won't be maintaining it from there. System.FinalException: Record is read-only: Trigger.updateCompetitors: line 24 I am writing a trigger to get all the Opportunity competitors into a field on Opportunity, however, getting an error while testing it.

Suppose there exists $n\in\mathbb{N}$ such that the n-th power of $T$ is $q$-contractive. Show that then $T$ has exactly one fixed point $\overline{x}\in X$.      The n-th power is defined inductively: $$ T^{n+1}(x):=T(T^{n}(x)), n\in\mathbb{N}. $$ And for a function $T\colon X\to X$, $q$-contractive means  $$ \exists 0\leq q&lt;1~\forall~x,y\in X: d(T(x),T(y))\leq q d(x,y). $$    Now to the proof.  I think I have to show, that $T$ is q-contractive, because then it follows with Banach, that $T$ does have exactly one fixed point. So I have to show, that there exists a $0\leq q&lt;1$ so that for all $x,y\in X$ it is $$ d(T(x),T(y))\leq q\cdot d(x,y). $$ And most likely I have to use the q-contractivity of $T^n$, i.e. that there exists a $0\leq q &lt;1$ so that for all $x,y\in X$ it is $$ d(T^n(x),T^n(y))\leq q\cdot d(x,y). $$  Can you help me? Why do polarized sunglasses remove (most) reflections on car windows?  I know that both lenses of polarized sunglasses are polarized in the same direction and I can see that reflections in my own windshield and the windows of other cars appear, disappear, or change depending on how I tilt my head, but why?  Why is the light in those reflections polarized?  edit: And why is most of the light in the various reflections on the interior of my own windshield and various windows/windshields at what seem like a variety of angles all polarized in a sufficiently narrow set of ways as to make polarized sunglasses work? I can't get into my field research prize Lag compensation with networked 2D games I want to make a 2D game that is basically a physics driven sandbox / activity game. There is something I really do not understand though. From research, it seems like updates from the server should only be about every 100ms. I can see how this works for a player since they can just concurrently simulate physics and do lag compensation through interpolation.  What I do not understand is how this works for updates from other players. If clients only get notified of player positions every 100ms, I do not see how that works because a lot can happen in 100ms. The player could have changed direction twice or so in that time. I was wondering if anyone would have some insight on this issue.  Basically how does this work for shooting and stuff like that?
