SQL Server has a long history of failed login attempts into the SA user , occuring about 50 times every 10-20 minutes. and Extended Event auditing shows that the client_app_name is "Microl office":    The PID refers to sqlserver.exe.   Incoming remote connections is disabled for this server so it can't be coming from outside the machine... No firewall rule exist for SQL server so incoming connections are blocked there too No jobs are attempting to login   Any ideas what else this could be or suggestions?

What is the definition of a timelike and spacelike singularity? Moderncv adding date of birth to personal information Xubuntu 18.04 Persistent Live USB: Will persistence be carried upon full installation to a machine? I've created an Xubuntu 18.04 persistent live USB stick and installed several softwares for web development, such as XAMPP, Sublime Text 3, Google Chrome, etc.. I did some configurations as well in the ~/.bashrc file.  I am wondering if these installation and configuration in my persistent live USB stick be carried over in a full installation in to a new machine using it. Do the glowing pillars in The Storm Halls do anything? I've noticed that occasionally if I shoot at (or near) the glowing red pillars they will kind of explode a bit for a second and then reform. Does this affect my attacks in any way? What about nearby enemies? Is this purely cosmetic (like pillars in other dungeons crashing down)? [Probability]need help to understand the following expression Quantum teleportation and no-communication theorem According to the Wikipedia article for the :     In very rough terms, the theorem describes a situation that is analogous to two people, each with a radio receiver, listening to a common radio station: it is impossible for one of the listeners to use their radio receiver to send messages to the other listener. This analogy is imprecise, because quantum entanglement suggests that perhaps a message could have been conveyed; the theorem replies 'no, this is not possible'.   According to the Jet Propulsion's recent article on quantum teleportation:   they can effect an entangled photon (B) with another photon (A) to change the state of the other entangled photon.  Doesn't this contradict what the no-communication theorem states ? Curved mesh topology 2 I am trying to model a violin belly and I am intrigued, how is it possible to make faces with soft / rounded edges?    The edges I do are totally straight (see the blue amoeba).  Also, do you have some idea on how to avoid the edge loops getting too "compressed" in the middle of the model (see the red amoeba) ?    I know the Subdivision surface modifier, but I want curved edges after applying the modifier... like in this picture :  Any help will be very appreciated. Thank you in advance!  Marcos  2nd part  In fact, I've tryied to model using nurbs and bezier curves, but I wasn't able to find any tool similar to loft that works with curves, then I was forced to convert it in meshes, the results were not terrific and I've started to move the vertices manually, a real pain... Unlike a guitar, each edge loop is on a diferente elevation on z axis and I have to keep the original dimensions, So I have to be extremely careful when using the subdivision suface modifier. I've already modeled this think on three different CAD softwares, but the meshes are far from good... I want to improve the edge loops, but it will be a long path... Thank you again. $\zeta_{15}$ is $15$th primitive $n$th root of unity.   Question: Find the structure of the group $Gal(\mathbb{Q}(\zeta_{15})/\mathbb{Q})$  I know that if $p$ is prime then $G=Gal(\mathbb{Q}(\zeta_{p})/\mathbb{Q})=\mathbb{Z_{p}}^*$ but when $p$ is not prime, I am not show how to solve this if not prime.  Does my required group have any relation to some cyclic group $\mathbb{Z_n}$, i.e. abelian  Would really appreciate your guidance as I have not got my head around these concepts of cyclotomic fields and Galois structure. Thanks Report this Ad Feature [S]he has the ears of a ...? Often, when overheard from far away, I find myself saying/thinking:     [S]he has the ears of a hawk!   Which doesn't really make sense as hawks aren't particularly well known for their sense of hearing.  Is there a common saying, equivalent to "eyes of a hawk", relating to someone's sense of hearing? Is the term "errored out" a grammatically correct phrase, or just a colloquial one? How do I make an HTML text box show a hint when empty? I don't know how to integrate $\displaystyle \int\frac{1}{x^{4}+1}\mathrm dx$. Do I have to use trigonometric substitution? Why can't I have a non-integral static const member in a class? I noticed C++ will not compile the following:  class No_Good {   static double const d = 1.0; };   However it will happily allow a variation where the double is changed to an int, unsigned, or any integral type:  class Happy_Times {   static unsigned const u = 1; };   My solution was to alter it to read:  class Now_Good {   static double d() { return 1.0; } };   and figure that the compiler will be smart enough to inline where necessary... but it left me curious.  Why would the C++ designer(s) allow me to static const an int or unsigned, but not a double?  Edit: I am using visual studio 7.1 (.net 2003) on Windows XP.  Edit2:  Question has been answered, but for completion, the error I was seeing:  error C2864: 'd' : only const static integral data members can be initialized inside a class or struct is this set a regular surface? I'm reading "Differential Geometry of Curves and Surfaces of Manfredo Docarmo" I'm doing  the exercises of the chapter 2. Here is the definition of regular surface that we are following:   I have problems with this exercise:   Is with the first part, I think that it's not true that it's a regular surface (the second it is). I don't know how to prove that something is not a regular surface. How is (p ∧ q ∧ ¬r) ∨ (p ∧ ¬q ∧ ¬r) ≡ (p ∧ ¬r) ∨ (¬q ∧ q)? Is it really distributive property? What are Multi-Zone/Matrix metering, Center-Weighted metering, and Spot metering? What about Partial?  Is there a good rule of thumb, or a few pointers, on when best to use each exposure metering mode? How come such different methods result in the same number, $e$? I guess the proof of the identity $$ \sum_{n = 0}^{\infty} \frac{1}{n!} \equiv \lim_{x \to \infty} \left(1 + \frac{1}{x}\right)^x $$ explains the connection between such different calculations. How is it done? What are the possible values of the Hibernate hbm2ddl.auto configuration and what do they do I really want to know more about the update, export and the values that could be given to hibernate.hbm2ddl.auto I need to know when to use the update and when not? And what is the alternative?  These are changes that could happen over DB:   new tables new columns in old tables columns deleted data type of a column changed a type of a column changed its attributes tables dropped values of a column changed    In each case what is the best solution? I need another LP-E5 type battery for my Canon 450D. Should I buy an original Canon battery or one of the many generic brands available? There are loads of cheapos on , for example.  I should add that the new battery will be added to my existing Canon battery in a battery grip.  Does anyone have any experience (good or bad) of using generic batteries?
