How can I make swap space?
How to increase swap space?
Matlab arrays operation Make it cost more to downvote without comment; make it hurt to leave a crap comment Possible Duplicate:    In the spirit of &quot;encouraging&quot; people to leave comments on downvoting, I would propose that if someone downvotes without a comment, I propose a heavy point tax, say 3x the current point cost for a downvote. If he or she downvotes and leaves a comment, then it costs the current amount. If someone leaves a crap comment (to avoid the &quot;charge&quot;) they get a painful spank (100 points gone or whatever the community decides) if and only if:  The comment is flagged Three (five? whatever) moderators agree it is crap  Common complaints Or, why my proposal is different.  &quot;  a &quot;   No it isn't. I specifically address the issue of leaving garbage comments to avoid the downvote tax, unlike the other proposals.   &quot;Some people want to leave anonymous (down)votes.&quot;  I understand that some might be fearful of retaliation. Is retaliation a real problem or a &quot;what if&quot; conjecture? (Where's the data?) What if we try it for 3-6 months and then circle back to see how well it works?  If a user starts retaliating against another user, they will be dealt with as are all other problem users. Nothing else is anonymous - asking questions, answering questions, editing questions, leaving comments, etc. and there is a clear benefit. What is the benefit to the community for having anonymous voting? I would argue &quot;none.&quot; Even though some people might want to leave anonymous questions, answer anonymously or anonymously edit a question, it is not allowed, because it is not good for the community.   &quot;But this will discourage downvoting&quot;  I agree, and I think that's a good thing, which goes to the philosophy of the site: promote good questions and answers. If a question or answer is poor, few will up-vote it. If is is really poor, it will get flagged and . If someone really wants to downvote, no one is stopping him or her. Just as we want quality questions and answers, we need quality voting.   It will require too much work to implement  Maybe. Let's ask if it is worth the effort. What benefit does anonymous, no-comment downvoting add to the site? It certainly doesn't allow the author to improve. What benefit would owned, commented downvoting add? It would hopefully allow authors to improve and discourage drive-by downvoting. Would me (or someone else) submitting a patch alleviate this complaint?   Jeff (or Joel) thinks this is a stupid feature, and you're stupid for suggesting it.  &quot;&quot; Is this a true statement?    Thanks for reading. Why aren't these loops homotopic? Let $S^1 = \{z \in \mathbb{C} : |z| = 1\}$.  Take the loops $f,g : [0,1] \rightarrow S^1$, $f(t) = 1$, $g(t) = e^{2\pi it}$.  I know these represent different elements in $\pi_1(S^1, 1)$, but I don't see why $F(t,s) = e^{2\pi its}$ isn't a homotopy between $f$ and $g$. What is the "Bootable flag" option when installing a distro? Is the "bootable flag" needed in today's distributions? If not, then why is it still in the installers? What is it exactly? Probability of sampling with and without replacement In sampling without replacement the probability of any fixed element in the population to be included in a random sample of size $r$ is $\frac{r}{n}$. In sampling with replacement the corresponding probability is $\left[1- \left(\frac{1}{1-n}\right)^r\right]$.  Please help me show how this is proved. Force MacBook to drain the battery while connected to charger I leave my MacBook Pro on my desk nearly all the time, connected to the charger with the lid closed, connected to an external display.  I've heard this is bad for the battery health, and everyone in my office have to replace swollen batteries every couple of years. I want to regularly discharge the battery, per , but I don't want to physically unplug it because that temporarily turns off the external monitor, and then I have to reconnect the monitor.  So I am looking for a software method of disabling the power input, to force the laptop to discharge its battery to 20% and then re-enable the power input. Referencing without captions appearing but keeping numbering How do I enable hardware virtualization technology (VT-x) for use in Virtualbox? Other word for person who does something to others but does'nt like it done to them This is a duplicate question but has still not been answered for me. I'm so close to the exact word - I know there is one out there - but the closest word I can find is a hypocrite --     a person who claims to have certain moral principles or beliefs but behaves in a way that shows they are not sincere.    The word I'm looking for is a person who does not claim things, but does thing to another and they consider it wrong or immoral to have done to them.

Shell script to send an alert mail if disk usage exceeds 90% Preventing robots from crawling specific part of a page Appendix without letter in TOC I wonder how a researcher send an unsolicited email to another one asking for feedback to their work. I guess it will be something like this?  Hello Dr. X To introduce myself, I am Y, in institute Z. I'm sorry if this email is not convenient at this time, but my work about A is highly relevant to your work in B, so I think it will be interesting to you too. If possible, can you take a look at it and tell me what you think? Here is the link:  Thank you for your reading, hope you enjoy it.  I wonder if the summary/abstract should be included in the email too, since the principle for  is to show everything you know about it. Maybe it's not necessary, since the title of the link should prove its interestingness nevertheless? I'd like to have your confirm. I'm also interested in the case where Y has no Z, and the link is just a collection of observations posted in a blog, not a full paper with proper citation and literary review. It is possible that the observations may have been covered in the field, but Y isn't aware of that yet. I also think that if the link is interesting enough, then putting a tracking method in there is fine too? Even if they finds out, they wouldn't feel insulted either, because they find that the link is indeed interesting.  Related: •  •  • 10 hour layover in Moscow Russia, do I need a transit visa?

Was Luke aware the Emperor was a Sith Lord? Similar to , I'm asking the more specific question, was Luke aware that the Emperor was a Sith Lord? I don't recall it being mentioned in any of the films.  If yes, at what point does he learn this? If not why did Yoda or Obi-Wan not warn him?  Perhaps he could have avoided being defenseless and struck by Force Lightning if he'd been made aware? ArcPy importing error after setting path? This questions has been asked before too and I did go through most of the suggestions.
