Certificate error when using Citrix Receiver
I have a DSLR (Canon 550D) and since I'm taking my first steps in the world of RAW photography I don't know which would be a good program to use to edit these files. I've tried  and  but wasn't satisfied. I'm sure there must be better software out there... "In here", "from here", and "at here" I just read the discussed topic "look here vs. look at here":  It's got me wondering.  What is the reason for not using the preposition at before here?  Is it because here is an adverb and it is wrong to use a preposition before an adverb?  What if we use here with its nominal meaning, as in "get away from here", or "It's really hot in here", and then say "Look at here" meaning "Look at this place"?    If it is wrong and there is some other reason why at here is incorrect but in here and from here are correct, what is it? Relevance of cycle detection in Pollard's rho integer factorization algorithm I've recently learned about Pollard's rho factorization algorithm, and the way I understand it, it works by using a pseudorandom sequence of integers $x_{k}$ ranging from $0$ to $n-1$, where $n$ is the number to be factored, to find repetitions in an unknown sequence $y_{k} = x_{k} \bmod p$, where $p$ is an unknown, non-trivial factor of $n$. Such a repetition $y_{i}=y_{j}$ occurs when $x_{i}\equiv x_{j} \bmod p$, which can be detected by checking whether $\gcd(x_{i}-x_{j}, n)\gt 1$.  From what I could find on the Internet, Floyd's cycle detection algorithm or a variant thereof is used to find such repetitions. And the reason for this is what I don't understand.   First, Floyd's algorithm requires that each element in the sequence depends solely on the element before it, which, even if it is the case for $x_{k}$, is not necessarily the case for $y_{k}=x_{k}\bmod p$. For example, assuming we want to factorize $6$, let's take the sequence $5, 3, 2, 4, 1, 0, 5, 3, 2, 4, 1, 0,\ldots$. The cycle period is $5, 3, 2, 4, 1, 0$, where every element is contained only once. However, if we take this sequence $\bmod 2$, we get $1, 1, 0, 0, 1, 0, 1, 1, 0, 0, 1, 0,\ldots$. Floyd's algorithm cannot be applied here to find the cycle period $1, 1, 0, 0, 1, 0$. Besides, we are not even interested in a cycle, only in repetitions. Whether we find the congruence $\bmod 2$ between $5$ and $3$, $5$ and $1$, or $4$ and $2$ in the first sequence is irrelevant.   Please correct me if my understanding of Pollard's rho algorithm as described above is wrong. But if it is not, it seems to me that one could just as well try out some random numbers between $2$ and $n-1$ and see if they share a divisor with $n$ other than $1$. So what is the benefit of using a cycle detection method like Floyd's algorithm?  I also found , but it is not answered, and the comment on the question does not really answer the question either. If $f$ is continuous and $\,f\big(\frac{1}2(x+y)\big) \le \frac{1}{2}\big(\,f(x)+f(y)\big)$, then $f$ is convex Let $\,\,f :\mathbb R \to \mathbb R$ be a continuous function such that $$ f\Big(\dfrac{x+y}2\Big) \le \dfrac{1}{2}\big(\,f(x)+f(y)\big) ,\,\, \text{for all}\,\, x,y \in \mathbb R, $$ then  how do we prove that $f$ is convex that is $$ f\big(tx+(1-t)y\big)\le tf(x)+(1-t)f(y) , \forall x,y \in \mathbb R , t\in (0,1)? $$ I can prove it for dyadic rational's $t=\dfrac k {2^n}$ and then argue by continuity ; but I would like a more direct proof .

What's the difference between dot syntax and square bracket syntax? Why can I only change my Stack Overflow name once every 30 days? jQuery - auto size text input (not textarea!) create multilingual node programmatically i'm trying to create a multilingual node using a php script.  I'm doing this:   $node = new stdClass();  $node-&gt;title = "Test ".mktime();  $node-&gt;type = "job";  $node-&gt;language = 'de'; // Or e.g. 'en' if locale is enabled  $node-&gt;uid = $user-&gt;uid;   $node-&gt;status = 1; //(1 or 0): published or not  $node-&gt;promote = 0; //(1 or 0): promoted to front page  $node-&gt;comment = 1; //2 = comments on, 1 = comments off  $node-&gt;path = array('alias' =&gt; 'das-ist-ein-test-'.mktime());  $node-&gt;body[$node-&gt;language][0]['value']   = "Body Body Body";  $node-&gt;body[$node-&gt;language] = text_summary("Body Body Body");  $node-&gt;body[$node-&gt;language]  = 'filtered_html';  node_save($node);   As long as i set $node->language to 'und' everything is working fine. But as soon as I set the language to 'de' or 'en' (both languages are activated in my Drupal installation) the body text doesn't get saved.  So my question is: can anybody provide me with a working example of how to store a multlingual node (de,en) into Drupal using program code.  Thank you One of my friends argues that princessship is the only word which has 3 identical letter comes together (s) ,but I think there is no word such as princessship.  Can anyone tell me whether this is a real word, and if there are any more English words which have 3 letters consecutively? I read this story 30+ years ago in grade school. A man crashes on an alien planet. He has a small amount of water and accidentally spills some, and the planet replicates it but it must destroy part of itself to do so.  The man then finds some stale crumbs in his pocket, puts them in a trough, and the planet replicates them as well, but it's disgusting to eat. The man eventually decides that his situation is hopeless, so he lays down to die on a table in a hot room and thinks he can at least give back to the planet some of the nutrients it sacrificed for him. He falls asleep, and when he awakens, he has been transformed into an alien creature that is perfectly suited and adapted to live on the planet without discomfort to himself or damage the planet. What is object slicing? Someone mentioned it in the IRC as the slicing problem. Parallel option performing worse on cluster I'm trying out oracles parallel option on a cluster and surprisingly I am getting worse results with the parallel option. I was expecting some improvement with the parallel option but certainly not worse results. I am wondering why this is the case, and if there is anything wrong with the way I am using the parallel option on my cluster.   I am using a degree of 4 when the number of CPU's I have is 8. I have tried adding parallel to the cluster directly ALTER CLUSTER cluster PARALLEL 4 as well as at the statement on both the index /*+ PARALLEL_INDEX(clust_index, 4) */and tables /*+ PARALLEL(4) */,   Here is my trace from the parallel:    Without parallel: Does the Force wane as you age? @Valorum said     ...not to mention the sheer strain that comes from continually using the Force at an advanced age.   To my feeble mind, this doesn't make sense. Approaching 900 years old, Yoda is still as strong as any whippersnapper in terms of Force power and usage. Despite his old age, Obi Wan shouldn't have any problems with using his Force powers.  This got me to thinking, does the Force begin to leave you as you age? Is it a flow of Force power that goes down based on (I hate to say this) a decrease in midichlorian count as you approach your expiration date? Will adding more RAM speed up my computer? Apparently, you can speed up your computer by adding more RAM. Is the amount of ram to be added is directly or indirectly related to the amount of hard-disk  space, processor speed, Motherboard etc... Can the memory of a RAM be compared with Virtual Memory and Cache Memory?  Note: About my PC Configuration: Intel core i5 processor, Motherboard DP55WB 4GB RAM, 700 GB Hard-disk space. Honey changing into unusable, hardened clump Prove that $\sum_{n=1}^{\infty}\exp\left(-n^{\varepsilon}\right)$ converges. Why does the "Unanswered Questions" tab show questions that have answers? Is it correct to say "12:00am"? I've read in various places the first minute of a day described as 12:00am.  Now, whilst I personally prefer to use 24h clock notation and therefore don't have this problem as I can simply describe this minute as 00:00, how is one supposed to express this time using am/pm notation?  Is 00:00am common (strange because there is no 00:00pm), or is the least-bad way to say 12:00am (strange IMHO because it seems to imply that the previous hour was 11:00am when it was actually 11:00pm)?
