I have inherited the computer of a former employee. My office is on a small network. I log onto the domain with his old credentials. I have tried changing it in Control Panel under user account settings but it does not give me that option. Maybe because it is the admin account? I've been using it for a while as is, but would prefer to see my name instead of old employees, but I would also like to keep all my account settings, files, docs, etc. I've also just upgraded to Windows 8. Thanks in advance for the input.  My user account properties:    Old user account properties, note, there is only one tab:    Computer name:
When I log in on a Windows 8 machine for the first time with my Microsoft Account (by providing an e-mail address), a new user folder is created:  C:\Users\dzinx_000   In previous versions of Windows, I could choose the name of this folder (it was equal to my username). As I use the commandline often, it is quite annoying to me.    Can I somehow rename it to dzinx?  Does simply renaming the folder break everything?
Why don't we consider centrifugal force on a mass placed on earth? Is gcc 4.8 or earlier buggy about regular expressions? I'm looking for a word which indicates that a person has adopted a quality suggested by their name, e.g. a person named Grace who is indeed graceful, or perhaps someone named Shepherd who has become a shepherd.  I have a strong notion that I once learned such a word, but I have forgotten it and have never re-discovered it. How to find the sum $$\sum^n_{k=1} (k^2+k+1)k!$$  What I tried as follows :   $$\sum^n_{k=1} (k^2+k+1)k!$$  =$$\sum^n_{k=1} (k^2)k!+ \sum^n_{k=1} (k)k! + \sum^n_{k=1} (1)k!$$  Now we can write $\sum^n_{k=1} (k^2) $ as $$\frac{n(n+1)(2n+1)}{6}$$ but what to do with $k!$ please guide thanks....... Just noticed a minor css issue on this question:    The related questions on the right hand side have some overlapping text in Chrome:        (This only applies to this very site, Meta Stack Exchange) I was trying to prove this question.   Q. If G is a group of even order, prove that it has an element a, such that a$\neq$e satisfying $a^2$=e.   I tried solving it using Principle of mathematical induction.  So, Let O(G)=2m, where m$\in$ $N$.   We proceed by induction on m.   For m=1, O(G)=2, $\therefore$ G contains two elements.  G=$\{{e,a}\}$. Now, e has order 1. So, a can not have order 1. $\therefore$ a has order 2. So, it true for m=1.  Now, let it be true for m=k.  Then, we have a group G of order 2k, where $\exists$ an element a$\in$ G, whose order is 2.   We wish to prove it for m=k+1.   Then G has order 2k+2.   I don't know how to proceed further. Limiting floats to two decimal points I want a to be rounded to 13.95.  &gt;&gt;&gt; a 13.949999999999999 &gt;&gt;&gt; round(a, 2) 13.949999999999999   The  function does not work the way I expected. Permission Subscribe to Dashboards: Add Recipients depends on permission(s): Subscribe to Dashboards Evaluation of Indefinite Integral resulting in Hypergeometric Function I am attempting to derive the result:  $$ \int \left(1+x^n\right)^{-1/m}dx= x\,_2F_1\left(\frac 1m,\frac 1n;1+\frac 1n;-x^n\right)$$  First, I start off with the binomial expansion of the integrand to get:  $$\int\sum_{k=0}^{\infty}\frac{(1/m)_k}{k!}\left(-x^n\right)^kdx  $$  Then, I pull out a $-1$ and interchange summation and integration:  $$\sum_k\int (-1)^k\frac{(1/m)_k}{k!}x^{nk}dx  $$  $$ \sum_k (-1)^k\frac{(1/m)_k}{k!}\frac{x^{nk+1}}{nk+1} $$  $$ x\sum_k \frac{(1/m)_k}{k!}\frac{(-x^n)^k}{nk+1}  $$  So, I'm just right there, but not sure how to express this series in the general form of a hypergeometric series with the two additional Pochhammer symbols.  I even typed this last series into Mathematica, and it returned the Hyper. Function. What am I missing, or how do I transform this last series into the desired form? Why is integration the inverse of differentiation, I mean why do I get the same function when I integrate and then differentiate the result? Is it a good concept to use multiple inheritance or can I do other things instead? I'm from the State of Kuwait and hold an Eritrean passport. I'm planning to visit UK in October but my visa will expire in November.    Is it OK to make a journey in the last month of my visa, provided that I make sure that I book my plane back before expiring date? What is the name of this castle part? Neural Network: MLP for regression with 3 continuous features, 1 categorical I am starting to study Neural Network. I want to build a MLP where I will feed it:   3 features which are continuous one feature which is categorical (48 classes)   How can I do this?  Before adding the categorical feature, I was using 'relu' activation function and 'lbfgs' as a solver in MLPRegrssor in sklearn.  I was wondering: how can I integrate this variable into the network? Should I do one-hot encoding? Should I keep relu as activation function or should I try sigmoid, softmax or something like that? How to prove the following limit?   $$\lim_{n \to \infty} (1+1/n)^n = e$$    I can only observe that the limit should be a very large number!   Thanks. Why can I vote to reopen a deleted question? I've seen .  Voting to undelete will not work because it was deleted by a moderator, but I managed to vote for reopening for some reason.  I doubt this is intentional, perhaps not as important, but still. Create an Application without a Window How would you program a C/C++ application that could run without opening a window or console? Does herd behavior influence the SO sites? Are you influenced by existing votes? That is, if a question or answer has a large number of up votes, are you more likely to vote it up (and similar for down)?  The reason I'm putting this question is this: on these sites we see how other people vote before we do. This almost certainly influences us (see resources, below) - just as we can be influenced by our  (people often naturally pick the busy one).  This trend may also be further influenced by rep - do we give more weight to the answer of someone with 10K rep than someone with 10 - even if they both have e.g. zero votes?  And if this does happen, is it even a problem?  I'm not looking here for solutions - right now I'm just curious as to whether this is something you recognise.  Clarification edit: I'm referring to voting here. Example: if you see a question or answer with 20 plus votes, are you more likely to vote it up than if it has no votes, or a negative number vote?  Bounty: I've been so impressed at the quality of answers and comments here that I'm offering a small bounty to encourage more great responses and discussion.  Wrapped up: Bounty awarded to the answer that received the most votes. In light of the question, it only seemed appropriate...  Resources: Why won't my YN-568EXII work with a flash trigger? I have a Canon 5DMk2 and have just bought 2 Yongnuo YN568EXII speed lights. I have an existing Yongnuo RF-603CII trigger, but I cannot get them to work together! Does anyone have any suggestions, as the manual is no use :( Thanks Steve How to attach my repo to heroku app
