I am travelling from Paris to Cologne with a one-day stopover in Brussels.  Where can I store luggage at the Bruxelles-Midi station?
Is there a place where one can leave luggage for more than one day in Brussels? It can be either in the airport or the central station.  I know that there are lockers in the central station. The problem is that these are usually restricted to 24h.  Are there any other services, in Brussels, that take luggage for longer than 24h?
Let's make the hot network questions icons clickable I would like to see the icons in the 'Hot Network Questions' right panel clickable, leading to the homepage of the site where the question comes from.  It would make it more comfortable to switch to the site when you want rather to visit it than to see that specific "hot" question. What are the shell's control and redirection operators? I often see tutorials online that connect various commands with different symbols. For example:  command1 |  command2 command1 &amp;  command2 command1 || command2     command1 &amp;&amp; command2   Others seem to be connecting commands to files:  command1  &gt; file1 command1  &gt;&gt; file1   What are these things? What are they called? What do they do? Are there more of them?    . Polynomial contrasts for regression I cannot understand the usage of polynomial contrasts in regression fitting. In particular, I am referring to an encoding used by R in order to express an interval variable (ordinal variable with equally spaced levels), described at .  In the example of , if I understood correctly, R fits a model for an interval variable, returning some coefficients which weights its linear, quadratic, or cubic trend. Hence, the fitted model should be:  $${\rm write} = 52.7870 + 14.2587X - 0.9680X^2 - 0.1554X^3,$$  where $X$ should take values $1$, $2$, $3$, or $4$ according to the different level of the interval variable.  Is this correct? And, if so, what was the purpose of polynomial contrasts? Prove,by vector method,that the point of intersection of the diagonals of the trapezium lies on the line passing through the mid-points of the parallel sides.    My Attempt: Let the trapezium be $OABC$ and that the O is a origin and the position vectors of $A,B,C$ be $\vec{a},\vec{b},\vec{c}$.Then the equation of $OB$ diagonal is $\vec{r}=\vec{0}+\lambda \vec{b}................(1)$ And equation of $AC$ diagonal is $\vec{r}=\vec{a}+\mu(\vec{c}-\vec{a}).......(2)$ And the equation of the line joining the mid points of $OA$ i.e.$\frac{\vec{a}}{2}$ and $BC$ i.e. $\frac{\vec{b}+\vec{c}}{2}$ is $\vec{r}=\frac{\vec{a}}{2}+t(\frac{\vec{b}+\vec{c}}{2}-\frac{\vec{a}}{2}).........(3)$. Here $\lambda,\mu,t$ are scalars. I do not know how to solve $(1)$ and $(2)$ and put into $(3)$ to prove the desired result. Please help me.Thanks. "Requires 50 reputation" to comment on deleted posts So I recently saw add comment (requires 50 reputation) on a deleted answer. After looking around a bit, it seems to be on all deleted posts now (only deleted posts, normal posts still say just add comment).  I'm sure it wasn't there before (I think it just said add comment (unclickable) or possible nothing).  It is also on , presumably the root cause is the same.  And yes, I do have more than 50 reputation (in case anyone was wondering).  Just to clarify, requires 50 reputation obviously shouldn't be there for users with 50 or more reputation. Choices:   Display nothing Unclickable add comment - probably not ideal Unclickable add comment (disabled for deleted posts) or something along those lines   FYI - You may be somewhat confused right about now if you can't  yet.

How to get the length of longest string in an array Show that there are $ a,b \geq 0 $ so that $ |f(x)| \leq ax+b, \forall x \geq 0.$ How do I ask LaTeX to exactly fill up a page? I understand that I can control interline spacing in LaTeX in a number of ways. The commands like ,  ,  come in handy in controlling the interline spacing. Each has its own speciality and circumstances of usage, as we can find in these discussions (, , ).  If want to go for a ready made solution for controlling line spacing, packages like  come in quite handy (built-in commands like \onehalfspacing or \setstretch for more finer controls).  Anyway, my problem is a bit different. I have some text (both in paragraph and list mode) which I want to fill up exactly one page. To complicate the scenario, it may even contain equations and graphics. (Let us leave aside floats.)   If I want to solve the problem statically, all I will have to is to play with some value of \baselineskip (or  \setstretch) until satisfied. While this works good for most of the cases, I will have to go through the process again when I want to delete or add some texts.  Would it be possible to have a dynamic value for  \baselineskip or  \setstretch so that my text always fills up one page? (Definitely within reasonable limits.)  Another idea will be to use a number of \vfills between some pieces of texts. But I think that this technique is usable for cover pages only.  I am not putting here an MWE. I think that one is not applicable.    The problem is not a theoretical one, I am preparing some kind of handout which I want to fill-up exactly one page. How do I merge two dictionaries in a single expression (taking union of dictionaries)? What are these stamps in my passport after I was advised to divert via the UK but didn't have a visa? I am from Myanmar. I was on my way to Venice from Brussels while holding Schengen visa (single entry). I bought a British Airways ticket to fly from Brussels to Venice. Unfortunately, on that day, all BA flights from Brussels were canceled. British Airway's customer service centre told me to go to from Brussels to London by train, where I could catch my flight to Venice. I took a taxi to Bruxelles-Midi train station and bought a ticket to London. A Brussels immigration officer inspected and approved my passport.   Then I had to to through UK Border Immigration. There, they said I can't enter to get my flight. Although I explained the situation with the airline and made clear of my destination (I already reserved my hotels in Venice, Switzerland and France as described in my travel itinerary), they detained me for some hours and also took my fingerprints on paper and photo.   They asked questions concerned about my finances and gave me a refusal letter for not having a transit visa. So I had to re-enter Brussels where the immigration officer put the below stamp in my passport. As I had a single entry Schengen visa, I had to buy another airline ticket to Venice and complete my Europe trip.   What do the stamps below mean on my passport?   Can they affect me and, if so, how and why, when I apply for another Schengen visa? Displaying attachments on visual force page I need to display attachments on a visual force page for the Case object.  This is the code I am using.

Please leave any feedback or questions about this FAQ on .     Two weeks ago, we  to directly address concerns over pronoun usage. We tried to anticipate likely questions, but&hellip; missed the mark by quite a lot. Based on Gareth McCaughan’s excellent post, “”, we’ve gone back to the drawing board and written a new FAQ that aims to address actual questions that have been frequently asked in these discussions.  If you read only one thing, the answer to question #1 under The Basics sums up our goals in publishing this guidance:     It would be rude to refer to a man as "she" or a woman as "he". Some people are neither male nor female and might, for instance, ask to be referred to as "they". When someone indicates what pronouns should be used to refer to them, please use the pronouns they state as you would others.   This is a learning process for most of us - from authors to readers to moderators to employees of Stack Exchange, Inc.  Let’s all try to approach this with good intentions and a willingness to learn from one another.  Big thanks to Gareth for leading by example here, and to everyone who has stepped up to ask and answer the important questions!  What's all this stuff about pronouns in The Code of Conduct?  The  has two direct references to pronouns:   “Use stated pronouns (when known).” “Prefer gender-neutral language when uncertain.”   What does all of this mean and how can I as a user understand and follow the CoC guidance? Linux command line. Move all files and directories in directory, except some files and directories How can I do a "broad" search for flights? Several airline and trip planning sites will allow you to check "I am flexible with my dates" or a similar option.  Is there any way to also search more broadly for location?  For example, if you wanted to leave from YYZ or YKF and arrive at any airport in California, can a search for such flights be done somehow?  I ask because when I plan plane trips, I want the lowest price.  I'm OK with leaving a day or two later if I save $200 (same with the return trip).  There are 3 airports within 80 km of me, I'll leave from the one with the cheapest flight. And I'm also OK with changing the trip to spend time exploring San Francisco instead of lying on the beach near San Diego, and that sort of thing.  Normally this would take dozens of searches, but I'd like to see it all at once. Help us test the shiny new "User Activity" page! (Plus a bunch of new features.) At what time intervals does ntpd update the time? I'm running the latest ntpd.   When I start ntpd my system time synchronizes with ntp server's ntp. After synchronizing I changed my system time manually using date command date -s '1997-02-22 12:00:00'   My system time got changed as per the date command.   NTPD is still running, I want to know at what time interval my system time will sync with the internet via ntp. Diffeomorphism group of the unit circle I am given to understand that the group of diffeomorphisms of the unit circle, $\operatorname{Diff}(\mathbb{S}^1)$, has two connected components, $\operatorname{Diff}^+(\mathbb{S}^1)$ and $\operatorname{Diff}^-(\mathbb{S}^1)$, the diffeomorphisms that preserve or reverse the canonical (counterclockwise) orientation, respectively.  Question 1: How does one prove that?  Question 2: Given $\Phi, \Psi \in \operatorname{Diff}^+(\mathbb{S^1})$, can one construct an explicit path joining them?  I'd be satisfied already with a proof that we can join $\Psi, \Phi \in \operatorname{Diff}^+ (\mathbb{S}^1)$, without giving the path explicitly. I tried the obvious path, $t \mapsto \dfrac{t\Phi + (1-t)\Psi}{|t\Phi + (1-t)\Psi|}$, but that doesn't seem to work.  Thanks.
