"I too" versus "me too"
"Who wants ice-cream?" — Should I say "(not) I" or "(not) me"?
Chrome: Site has updated in the background I keep getting these notifications despite not having an RT tab open. What gives? Is causality a formalised concept in physics? Of course preventing them from getting stolen is the top priority, but invariably, someone is going to get jacked. What are some good practices to minimize the damage incurred when your PC is stolen?  Given most of our PCs contain our entire lives, its frightening to know that all this information can be in someone else's hands.   Some ideas i had (a bit paranoid, i admit).   keep encrypted backups.  Use truecrypt to have double encrypted (with strong password) volumes where you store your personal data. schedule Eraser to run every evening so that potential thieves couldn't undelete (and subsequently retrieve) sensitive data do all your banking in a virtual machine.  Keep the virtual machine volume encrypted, and on a portable usb drive that you carry with you / keep in a safe. have applications that phone home (or hit something to leave an IP trace) upon connection to the internet (can someone suggest a good solution for this?)   Does anyone have any other suggestions? So I had an exam today and one of the questions were: Give an example of a function $f$ which is nowhere continuous but $|f|$ should be continuous at all points. At first I had no idea how to do it then I came up with this, even though I know it's wrong:  $$f(x)= \begin {cases} \ \sqrt{x}&amp;\text{if }x &lt;0\\ \sqrt{-x}\ &amp;\text{if }x &gt; 0\\ \end {cases}$$  Like I said I know it's wrong..but can someone give me an example of this? Thanks. The ship flying away from Rey in her flashback of being left on Jakku looks like one of the ships in the group that takes her away when she is captured.  If so, and it is a First Order ship that dropped her off, this is an interesting Easter egg. in questions, answers, and comments. Can we get something like this going on Stack Overflow?  I think it’d be appropriate as I at least pretty often want to write something like n^2 and would benefit greatly from prettier markup. Bibliography with Metadata: I am constructing a bibliography of as much of the prior research in a field I am working in. I would like to use BibTeX to print the citation in the pdf, and then I would like to add the details of the paper after the citation. Only then would I like to print the next citation. For example:  [1] Jahan M. Dawlaty and Yunquing Chen. Measurement of the optical absorption of graphene in the terahertz. Applied Physics Letters, 2008. Research Group: Cornell Pump Wavelength: 500 nm. Probe Wavelenth: 7 microns. Relaxation Time: 50 fs. [2] Paul George and Dmitry Vekslar, Measurement of Ultrafast Carrier Dynamics in Graphene. Applied Physics Letters, 2009.  . . . and so on. Does anyone know how this could be done? Could normal users have an easier way to flag for migration? What is momentum really? Best answer versus best solution Number theory lemma - $x^2 \equiv 1 \pmod p$ implies $x\equiv\pm 1\pmod p$ I am confused by the orientation of a topological manifold. My understanding is: An orientation of a topological manifold is a choice of generator of the $H^n(M,\mathbb Z)$. So given a manifold, we could have 2 orientation defined on the manifold. For $\mathbb{CP}^2$ on orientation is determined by the complex structure, the other orientation is denoted by $\overline{\mathbb{CP}}^2$. And it is well known that there is no orientation reversing map from $\mathbb{CP}^2$ to itself.  My question is: are they homeomorphic? I guess they are not homeomorphic. But I am confuesed, doesn't the orientations defined on the same manifold, how come after reversing the orientation they become not homeomorphic? Running tcpdump starts ssh flood I have runtime Linux running in a PLC. My development machine is running Ubuntu 14.04. The PLC and the development machine are connected through a five port switch. I ssh to PLC from my development machine to transfer executable of a networking application that I develop on my development machine.   I run tcpdump on PLC to debug the kind of packets my network application is receiving BUT as soon as I start tcpdump, there starts a flood of ssh sync and acks back and forth from my ubuntu machine to the PLC. The LED lights of ethernet controller of PLC as well on the switch start blinking rapidly. The flood overwhelms the PLC and it almost dies down while all other packets get dropped. It feels like a DOS attack whenever I run tcpdump but as soon as I stop tcpdump, everything calms down and gets back to the normal.   I would like know remedy on this problem and why it happens?     Any help would be appreciated. How to detect, from browser, if user is running in Remote Desktop session? How to declare a structure in a header that is to be used by multiple files in c? If I have a source.c file with a struct:  struct a {      int i;     struct b {         int j;     } };   How can this struct be used in another file (i.e. func.c)?  Should I create a new header file, declare the struct there and include that header in func.c?  Or should I define the whole struct in a header file and include that in both source.c and func.c?  How can the struct be declared extern in both files?  Should I typedef it? If so, how? In the previous version the logout button is under your username, which it can be found by clicking the down arrow. However, in the new version, after a couple minutes of searching, it is under the "site-switcher" button:        This is really illogical since the logout button is usually under your username, including Google and Yahoo! services.  I suggest bringing back the  which will definitely benefit new users and even old users. Selecting specific row in attribute table using ArcPy (without iterating through whole table)? How do you post to an iframe? How do you post data to an iframe? How can I convert a Unix timestamp to DateTime and vice versa? There is this example code, but then it starts talking about millisecond / nanosecond problems.  The same question is on MSDN, .  This is what I've got so far:  public Double CreatedEpoch {   get   {     DateTime epoch = new DateTime(1970, 1, 1, 0, 0, 0, 0).ToLocalTime();     TimeSpan span = (this.Created.ToLocalTime() - epoch);     return span.TotalSeconds;   }   set   {     DateTime epoch = new DateTime(1970, 1, 1, 0, 0, 0, 0).ToLocalTime();     this.Created = epoch.AddSeconds(value);   } } How do I kill the lockscreen after the Windows 10 anniversary update?
