I'm making a website for my brother's webcomic, which was previously hosted on Tumblr. What is the most efficient/logical option for storing the pictures?   Downloading and putting the path in the Db Storing them in the database, base64-encoded linking directly to the pictures on Tumblr   wat do?
So I'm using an app that stores images heavily in the DB. What's your outlook on this? I'm more of a type to store the location in the filesystem, than store it directly in the DB.  What do you think are the pros/cons?
Speed of light when accelerating I'm studying special relativity and saw the 2 postulates of Einstein. The most remarkable one for me is the universal speed of light. Einstein postulated that the speed of light in vacuum is the same for all inertial observers, regardless of the motion of the source. But what if we are accelerating and we are changing from one inertial frame to another, how will we observe the speed of light? Is it still the same? I suggest it's not? Because I alread saw a small introduction to general relativity where the light will bend in a gravitational field and therefore also when you accelerate. So does the speed of light change because it bends? Do 'learn by heart' & 'learn by rote' mean the same? Here in India, both the phrases learning by heart and learning by rote are taken to have the same meaning, i.e., blind memorisation without true understanding.    However, some sources say that to learn something by heart implies that one knows something so well that it has been thoroughly internalised and imbibed.    So is it wrong to conflate the two? So when I got Steam working offline I had 26 games listed in my library but only 2 installed. Recently I brought a bunch more so I want to update my library on my Offline PC with the full list that's on my Online Laptop.  I thought that all I would need just copy the data from userdata/[ID]/config/localconfig.vdf however when I do the number goes down to 2 (the number of games I do have installed) and also the OST I got with Monster Monpiece doesn't appear. When I restore just that file the list and the music listing returns.  So what do I need to copy over from my Online Laptop to the Offline PC to update the list of games in the library? Fix missing ssl-cert for subdomain www. using redirect or similar What is the la command? I just mistyped ls as la. Without noticing, I ran it:  tim@Hairy:~$ la detection.sh   output-2.jpg  output-4.jpg  output-6.jpg  output-8.jpg Test1.pdf output-1.jpg   output-3.jpg  output-5.jpg  output-7.jpg  output-9.jpg          tim@Hairy:~$ ls detection.sh   output-2.jpg  output-4.jpg  output-6.jpg  output-8.jpg Test1.pdf output-1.jpg   output-3.jpg  output-5.jpg  output-7.jpg  output-9.jpg    What's the difference between ls and la? TexShop will not compile without trashing aux files after every error I have a couple of LaTeX files with the same problem. If I produce an error, fix it, and then try to compile a pdf, I get the following error.  )Runaway argument? {{ !

Any thoughts on what is going on and how to prevent this annoying extra step?

Am traveling from Cairo to Moscow via Swiss Air How can I get a significant overall ANOVA but no significant pairwise differences with Tukey's procedure? I performed with R an ANOVA and I got significant differences. However when checking which pairs were significantly different using the Tukey's procedure I did not get any of them. How can this be possible?

I heated the pan first, added olive oil, let it heat, then added chops. After I was done, cleaned it immediately under water, and noticed white cloud looking areas on the bottom of the skillet. They won’t wash or rub off  Do I need to return these? I did buy them for the look as well. What are the best practices for modeling inheritance in databases?  What are the trade-offs (e.g. queriability)?  (I'm most interested in SQL Server and .NET, but I also want to understand how other platforms address this issue.) General relativity is expressed in terms of differential geometry, which allows you to do interesting things with the coordinates: multiple coordinates may refer to a single point, eg. the  has whole lines at the top and the bottom that correspond to the North and South poles, respectively; or a single coordinate may refer to multiple points, for example by using inverse geometry the origin refers to all the points infinitely far away.  So, is the singularity just a single point in the curved spacetime, or can it be a more extended object, described by a single coordinate? Nice proofs of $\zeta(4) = \frac{\pi^4}{90}$? I installed an alpha or beta, am I up to date with the final release if I keep upgrading? I installed an Ubuntu alpha or beta and have been keeping it up to date.   So, Should I presume that my system has automatically updated to the next alpha or beta, and will be running the official release when it's finished? Introductory text for lattice theory I want to enable GPU rendering, but there is no option in User Preferences > System:    Why is this? How can I get cycles to render using my GPU? Proof of inequality using AM-GM inequality prove that $x^2 + y^2 + z^2 \ge xy + xz + yz$  I tried proving it the way I prove $x^2 + y^2 \ge 2xy$. But it just doesn't seem to work. I tried using AM-GM. Should I be using GM-HM or AM-HM? I really don't know what the problem is and I'd appreciate any help and a full proof explanation. Thanks. Lost my Downloads folder both from Dock and Finder I did something stupid apparently and lost my Downloads folder both from Dock and then when I opened Finder to drag it down to the Dock it somehow got deleted in the desktop.  Now although I can see the folder exists (e.g. by searching in Spotlight) I do not know how to restore it in the Dock and in Finder as well. Any help please? How to change permissions of multiple files found with find command?
