Another phrase for "a chicken and egg situation" Is there any other phrase that conveys the same meaning as  the phrase "a chicken and egg situation" especially if one has to use this phrase in an official/corporate set up? How can I force a long string without any blank to be wrapped? I have a long string (a DNA sequence). It does not contain any whitespace character.  For example:  ACTGATCGAGCTGAAGCGCAGTGCGATGCTTCGATGATGCTGACGATGCTACGATGCGAGCATCTACGATCAGTCGATGTAGCTAGTAGCATGTAGTGA   What would be the CSS selector to force this text to be wrapped in a html:textarea or in a xul:textbox? Have we managed to make a perfect vacuum? Have we managed to make a device without any atom inside it on earth? I was reading about vacuum , and I found in the examples part  that even on the best man made vacuum devices, there are still millions of "molecules per $cm^3$". So my other question here is, what are these molecules and what is the mass of them? How can I determine that I am looking at the block I need? I want to execute a command if I am looking at a specific block. A command should only be executed if it is targeted.

Outlook: scheduling recurring out-of-office? In Outlook, is there a way (or an add-on that can do it) to schedule a recurring out-of-office message?  I work 4 10's, so I'm out of the office every Monday, and it's a bit of a pain to have to reset my out-of-office message every single week. Detect an internet connection activation with Delphi I've been using a 3G wireless card for a while and every time I connect, my anti-virus fires up the updates.  I'm wondering what is the Win32 API set of functions that I can use to, either, get notified or query about the event of an Internet Connection coming up?  And is there already a set of ported headers for Delphi? NOR Gate is Working Correctly with Vcc Pin Disconnected I am working on the following problem asked in an examination: "What is the maximum number of cylindrical pencils of 0.5 cm diameter that can be stood in a square shaped stand of 5cm × 5cm inner cross section? 1. 99    2. 121   3. 100    4. 105." A simple calculation yielded me the answer 100.  But the answer in the key is 105. I don't how such an answer is possible. Any hint please.....Thanks in advance! UK visa requirement: Residence or citizenship? On gov.uk's  it is indicated      Check if you need this visa if you’re visiting from outside the European Economic Area (EEA) or Switzerland"   “Visiting from” makes you understand that the country you regularly live in is relevant, thus you can avoid applying for a visa if you are visiting from Italy (as country of regular residency).  As a matter of fact, if you proceed to make the check, the question to answer is "What passport or travel document do you have?", not really consistent with the indication previously given.  So, what is relevant: the country you live in with regular documents (and where you leave from to visit UK) or the country of origin which issued the passport?  To be practical, a Moldovan who is an Italian resident with regular resident card and Italian ID card (but with the note "not valid for expatriation") can avoid applying for a visa if he wants to spend a week-end in London (thus visiting from inside EEA)? What is the function of this circuit? Just wondering if someone can give me an explanation for this capacitor layout - what is it's function? The chip to the right is an ADC.  Circled in blue.

What caused the apocalypse in the Hunger Games? So the stories of the Hunger Games are set in , a post-apocalyptic society situated in North America. Is there anything to explain what caused the Apocalypse? Whether from the main books, any extra material or interviews? (No fanfic please.)  As well as the cause, is there any indication of when the apocalypse happened? And how long after the apocalypse are the events of the Hunger Games? I am looking for a exact derivation of a relation between redshift $z$ and distance $d$.  What I know is the definition $$z=\frac{\lambda_{\text{observed}}}{\lambda_{\text{unshifted}}}-1=\sqrt{\frac{1+\frac{v}{c}}{1-\frac{v}{c}}}-1$$ and that the Hubble constant $H$ as a function of $z$ is: $$H^2=H_0^2\left(\Omega_m\left(1+z\right)^3+\Omega_{\Lambda}\right)$$  How can I use this to derive the distance?
