Firt things first, needless to say that I'm still a newbie haha.  I've been learning how to model with extruding vertex and faces, instead of starting from a cube.  Everything went pretty well until I decided to add a Subdivision Surface modifier to smooth everything and I found this(Also happens when I right click and check shade smooth):    Also I let you see the X-Ray version, which made worry:    So thanks in advance and any help would be appreciated :3
While rendering a mesh with smooth shading on, I get a dark region/shadow on certain faces. The effect is more evident when smooth shading is applied to a mesh containing ngons, with the ngons turning black when rendered.   The blackening effect is visible in the viewport too.  How can I solve this problem?
I am trying to think of a non-colloquial word or phrase that means "practice what you preach." I would appreciate any suggestions. Thank you! Why do my lamps require an insane "strength" value of 1 million? recently, I was using mesh planes to emit some light, and they had a strength of 8.0.. this worked well now, I want to swap these out for area lamps (to improve performance) i've positioned these area lamps in the place of my emitter polygons i've scaled them such they have 1.0 transform scale, and in the lamp settings, I set the size to 1m across (to size-match the previous emitters) the problem is, the lamps require a crazy "strength" of at least 1 000 000 (one million!) to produce any reasonable amount of light... this seems bonkers! point lamps, area lamps, and the others, are all effected my scene is scaled using the Centimeters preset.. the foreground is only a meter a way, and the more distant background is more like 5 meters back i've paid special attention to the sizing and scaling of this scene, I can't figure out why the mesh emitters are working with a sane Strength of 8, and the lamps require something out of this world? something must not be right...     Edit: Remastered scene corrects scales, problem persists       i've remastered the scene so that all of the objects have a proper scale factor of 1.0 this should correct any sizing discrepancy/confusion my scene must be in centimeters preset, all my other work is in centimeters the area lamp size is now definitely 1m, as highlighted in the above screenshot (and it is not affected by the 1.0 transform scaling factor, also highlighted (I also verified the delta scale is also 1.0)) despite correcting the scaling of my scene, strength 1 000 000 is still required is blender simply not accounting for my scene's Unit Scale setting? Earlier i was not specifying a custom log format, and the captured request headers were getting printed fine. I wanted to log the unique-id-header, but could not find any way of doing so. So i copy pasted the log-format mentioned on , and unique id started getting logged.  Unfortunately, now the captured request headers are not getting logged. The %hrl and %hsl are coming out as empty strings.  Very weird.

Why (in relatively non-technical terms) are Calabi-Yau manifolds favored for compactified dimensions in string theory? Stop iPhone alerting me when I'm in a phone call When I'm in a phone call, I still get alerts for emails and texts. The noise will play and, if the phone is on Speaker, it will vibrate -- often leading the person I'm talking to wonder what that weird noise was.  Surely there must be a way to silence the phone while you're talking on it. It's very distracting to have beepings going off right next to your ear! How to change Function (Fn) Key behavior on wireless Logitech keyboard I do have a wireless Logitech K750 keyboard (silver Mac version) connected to a Lenovo ThinkPad (via the unifying USB receiver, together with a wireless Logitech mouse M705) and currently running Ubuntu 12.04.  By default the F-keys are mapped as multimedia/function keys, e.g. Play  /Pause. As I don't use them very often, I want the F-keys to behave like the "real" F-keys (F1-F12). How can I do that?  I know there is an option in the BIOS settings, but this only toggles the built-in keyboard of the notebook, not on my wireless keyboard.  I know there is a way to change this for the Apple wireless keyboard (), but there is no "parameters" directory in /sys/module/hid_logitech_dj/.  Any ideas? Or is there maybe a way to do this in a later Ubuntu version (13.04)?  UPDATE:  lsusb -d 046d: shows Bus 002 Device 005: ID 046d:c52b Logitech, Inc.

I am looking for a way to convert a long string (from a dump), that represents hex values into a byte array.  I couldn't have phrased it better than the person that posted .  But to keep it original, I'll phrase it my own way: suppose I have a string "00A0BF" that I would like interpreted as the  byte[] {0x00,0xA0,0xBf}   what should I do?  I am a Java novice and ended up using BigInteger and watching out for leading hex zeros. But I think it is ugly and I am sure I am missing something simple. Community isn't on ~15 sites! I was looking at the Community user's profile, and I noticed that there was about 15 sites missing in the "accounts" tab. There's a little over 120 sites on SE, and, there's about 15 sites missing from this count. Why is this happening?    Additionally, clicking on view more just shows one account, on Area51: How to prevent a coauthor from stealing the article? Please go through the following incidents to understand the problem.  Mr. A is a Ph.D. student of some institute who was working with Prof. B of another institute on a very interesting mathematical problem since last three years. Recently, they came across a significant solution to it. They wrote a research article to publish in a very good mathematics journal that accepts the online submission.  Prof. B wanted to submit it to the journal by himself. Mr. A agreed.   A few days ago, Mr. A wanted to know about the submission of their article via telephone. Prof. B informed that the article is submitted. But, Mr. A received any confirmation e-mail neither from the journal nor Prof. B forwarded the submission mail to him. Prof. B did not upload it in arXiv, which is a free preprint repository.  Mathematics journals used to take a long duration to review and publish an article. Prof. B told that submitting this article to arXiv will immediately attract community attention. Many researchers will start working in the new direction. As a result, Mr. A and Prof. B may lose their opportunity to work on that problems. Also, the article may be stolen.  Mr. A did not ask Prof. B to forward the submission confirmation mail to him. Prof. might think that Mr. A is suspecting him. It may affect the relationship. Also, Prof. is a very powerful person in the administration, who may prevent an opportunity for Mr. A to gain a job. Again from some of his friends, Mr. A came to know that Prof. had distributed related research problems to his collaborators.  As a consequence, Mr. A is thinking that Prof. has submitted this work in his own name and he has lost his credit as the first author of this article.  Now the question is: How Mr. A may save his credit and his work without hampering his relationship with Prof B? A subspace $X$ is closed iff $X =( X^\perp)^\perp$ Let $X$ be a subspace of a Hilbert space $H$.  prove:  $X$ is closed iff $X =( X^\perp)^\perp$   I do not know how to proceed. any hints would be appreciated.  thanks.  $X^\perp = ${ $y \in H$:$\langle x,y\rangle = 0 \forall x \in  X\}$.

Resize multiple layers around their respective anchor points Are all limits solvable without L'Hôpital Rule or Series Expansion Is it always possible to find the limit of a function without using  or ?  For example,   $$\lim_{x\to0}\frac{\tan x-x}{x^3}$$  $$\lim_{x\to0}\frac{\sin x-x}{x^3}$$  $$\lim_{x\to0}\frac{\ln(1+x)-x}{x^2}$$  $$\lim_{x\to0}\frac{e^x-x-1}{x^2}$$  $$\lim_{x\to0}\frac{\sin^{-1}x-x}{x^3}$$  $$\lim_{x\to0}\frac{\tan^{-1}x-x}{x^3}$$ These 2 questions have clearly wrong answers with upvotes. And they're still getting votes.  The log file one especially could be tried out, it would fail, but someone still voted it up. A downvote and comment has no effect.  Like we have "vote to close", what about a "vote to delete" for answers. I'd suggest a fairly high rep limit.

How to keep vehicles upgrades equipped in Jetpack Joyride? I have Jetpack Joyride for Android, but every time I start the game I have to equip the magnetic upgrades to all vehicles, except the teleporter, which is the only one already equipped.  I had once a game crash that undid my last 2 magnets purchases, so I ended up with only the teleporter and 20k less in cash. After that, I've bought every vehicle magnet, but still the only one that will remain equipped is the teleport.  Anyone already found some similar bug? How could I fix this, it's kinda annoying have to mannually enable 5 different upgrades every time I want to play.
