• Impossible to update sqlite3 on El Capitan

  I'm trying to update 3.8.10.2 to 3.10.2 sqlite3. I downloaded the source code, extracted, run make and make install. However, when I had finished, I was still running the old version. Then, I downloaded the files binary mac and tried to rename the old binaries of sqlite3 using the terminal. Who did not either, as I denied permission, even if I used sudo. "mv: Rename/usr/bin/sqlite3 in/usr/bin/sqlite3-old: operation not permitted". I tried to use other connections, with the same result.

  So, I have no idea where to go next. I could just use 3.8.10.2, but I am trying to learn Rails development, so I need the most recent version. Any help would be appreciated.

  I figured out how to use ruby to update sqlite3. "all I had to do was run"gem install sqlite3 - v ' 1.3.11.

• How to get decent macro shot with my T3i + EF 70-300mm f/4-5. 6 IS USM

  Someone here can direct me to a good tutorial on getting the macro shots decent with my objective T3i + EF 70-300mm f/4-5. 6 IS USM?  I'm pretty good in online searches, but I can't find are reviews and unboxings .  Even the manual I found isn't really give instructions re: macro, even if the lens itself says '1.5m/4.9ft MACRO' right on it.

  Thank you very much in advance for any help!

  To use the lens for close-up photography, zoom focal length max (300mm for example) and run the tune-up to the minimum focus distance.  The distance of the development of saddle is close enough consider it is a zoom 70-300mm lens... but it's nowhere near as close as a dedicated macro lens to true.

  You can get close... There are two ways to do this.

  (1) you can use a near plan diopter.  So that the lens you want the Canon telephoto lens 500 d (specifically you want the version with diameter of 58 mm threads to attach to the front of the lens 70-300 mm).  It's about $85.  It is a goal to two elements (which is good better than any diopter close-up of part 3).

  (2) you can use "extension tubes".  An extension tube is (believe it or not) exactly what the name says... it is a hollow tube... and it extends the distance between the lens and the camera body.  You attach to the camera (such as a lens) and then set the goal to draw instead of the body.  This positions the lens away from the plan of the image inside the unit and, therefore, range full tune-up of the camerea is shifted more near the camera (focusing more close distance was 1.5 meter without extension tube, but will be reduced to 42 centimeters just with the attached Canon 25 mm extension tube).  It allows not only the camea to focus at a distance closer, it also increases the size of the image) extension Tubes don't have any glass in there - they are completely hollow.  The body of the tube a pine e-mail to transmit signals through so that the camera body and the lens will always be able to communicate.

  The Canon 25mm extension tube is about $140.  Kenko is another popular brand (their tubes are delivered as a 'game' of three different lengths).

  Whether you use tubes extension or close-up diopters, Cannon suggests that you should manually focus the lens.

  When you arrive at very close distance of focus, depth of field can become quite shallow.  If shallow you can't get as much of your subject in focus as you want.  Use the Hard-Core (a) macro photographers a tripod (because after precisely focusing...) "If your body moves a few millimeters, it may completely lift the subject outside the home).  If you do not want to make sure that you do not move (and the best way to do that is usually to use a stationary object to hold the camera - as a tirpod.)

  They can also use a technique called "focus stacking."  The development of stacking is to take several pictures.  You take a picture, tweaking the development by a few millimetres and take another shot and repeat until you have enough plans to stack the subject of front-to-back with all the positions of different orientation.  The images are then merged using software (Photoshop will do, but there are third-party products that are dedicated to the development of stacking as well.)

  I did it by wrapping a piece of tape around the ring to focus on my goal.  I then focus point of closest focus and use a marker to mark this point (on the Strip).  Then I focus on the point most distant from the focus I care and mark this spot on the Strip as well.  Now I take a series of photos... each, then slightly focus a little bit at a time, take another picture, and repeat until I got enough to get the closest points to the farthest, I scored on that tape.

  More difficult Basic macro photographers will sometimes use what is called a rail development.  It is a track that Mount you on the tripod and then set the camera to a carrier rolling on "rail".  Rail has fine adjustment that allow to move the camera with control.  You run the rail back (furthest point), then focus your goal for the closet focusing point on your topic.  Rather than turn the ring on the lens... you use the buttons on the focus rail - which physically moves the camera forward.

• edges blur photo stacking

  The macro picture is a fusion of ~ 30 photos, F/5, 0.8 s, developed by increments ~0.7 mm, camera on rail development. Apparently there are areas along the edges of the layers blur. I tried F/8 and F/10 option hoping greater the DOF can help, but the same effect appear.

  This kind of effect is regularly whenever the subject is very complex and rough texture. Is it possible to reduce or eliminate the effect? I am beginner in PS. I'd counsel a sharing experience.

  Pawel

  

  Yes, Photoshop does not always the best choice of layer when it comes to focus stacking.  Rather than trying to guess which of 30 masks the layer to change, I'd be inclined to flatten the battery defective and align and the mask of the image in a new battery.  Either select the flattened pile and the new layer and go to edit > Auto alignment of layers, or just put the new layer of difference and align manually.  I always lock the position after having done this, because I seem to always manage to push out of alignment if I don't.

• Record audio from the computer in a rail hearing

  Hello

  I was wondering if anyone could tell me how to record audio from my computer in a rail at the hearing?

  Under Hardware Audio in the preferences, I joined entry as a default entry, but when I click on save, it does not record anything.

  Would appreciate any help.

  Thanks in advance.

  I recommend using SoundFlower.  He disapproved of and such mentioned - is more developed.

• Problem with the development of stacking

  I'm trying to focus stacking of flowers micro images using Auto Align and Auto Blend. It seems that the auto mix has bad withedges in some cases and place a halo/fringe of up to 20 pixels around the edge. I tried creating and transparent initialization of the tones and colors with different, but the results disappointing.

  The areas in question are at various locations in the image, including the Center. I shoot with a tripod and the development of rail to move the camera/lens in the depth of the subject.

  This culture is the center of the image.

  

  Any advice?

  Also, how many layers is best?

  Thank you very much

  Michael

  Very interesting.

  In particular, around the part of the flower (Stamen?) which is in the foreground, there is really no frame where the bottom is crispy completely to the edge of it.  When it is in focus, the background is blurry, and when the bottom is in short the Stamen is part fuzzy and blocking of the background.

  Maybe it's a case where you have to clone or sharpen the parts of the image selectively to hide this problem.

• How to open a file of unidentified developer?

  I try to open and install as a plugin for Final Cut Pro X. Plugin has been downloaded from the website of the official Developer (PixelFilmStudios.com).

  To make the story more short - button 'Still open' in security settings doesn't work :/ I always get the same information that is "unidentified developer. It looks like a bug or sth. I'm not sure. Please look at the screenshot below

  

  The question is: How can I install this plugin?

  additional information:

  Try this:

  Select the program package or App. CTRL - or RIGHT click, and select open in the top of the context menu. Click the Open button in the next dialog box. It works with the unsigned applications, but it may not work with an installer.

• Have CarPlay - you arrested development?

  I bought a new car and a past due the CarPlay navigation system. I thought that the future is CarPlay or the equivalent of google - Yes, I tested both. But I must say that the two are very very disappointing.

  1 Siri:

  When you use Siri with Bluetooth, all right. Not useful each time, but the iPhone understands me. When you use CarPlay, Siri don't understand me anymore. The phone is in the same place in the car.

  2. maps:

  Why you do not support true navigation additional apps to maps? Maps is not as powerful as real navigation applications. There are a lot of things bother me:

  -No 3D view

  -No sign, for example tempo-limit,

  -The contrast is very bad. It is not easy to see the other roads

  -On the highway you'll see the road, just a vertical line, nothing around > This is not useful. I want to see how he is for the next round or my destination,

  -While driving and navigation time is enabled I can't zoom out.

  -For journeys over long routes maps suggests me are not the best.

  -Siri do not understand where I have to go,

  -More than one-stop? Well...

  -... and many more things real navigation systems or applications can do.

  Please at least improve CarPlay cards.

  3. integration of the car

  Well, I can use my remote control on the steering wheel. That's great. But as long as the car rolls. A large problem is that CarPlay information are not displayed on the screen at the wheel - only on the screen in the middle of the car. So I can't take a look at the road.

  4 applications

  You are supported audio applications. Why?

  So, I really want to try. I'm the only person who is not satisfied with it? You will develop new features? If this isn't the case, you will give other people the opportunity to develop applications for the navigation? I forgot a select all the options for the cards or CarPlay?

  Thank you for your help.

• iTunes late development and scale of problem

  I recently downloaded iTunes a few days ago. The program runs very slowly and in the iTunes store my cursor is not properly calibrated. The screen itself is also cut makes it difficult to navigate the store, especially combined with the slow performance.

  I tried to reinstall and other attempts to solve without success. I have a decent laptop, so this isn't a problem.

  Anyone else knows this or know of a fix? Thank you!

  These errors are usually the result of the use of the Windows options for expanded fonts with which iTunes does not work with or scaling the DPI. Try to set these default/100% and see if the problem with iTunes disappear. It will not help if you need to use these features for best results in other software, but at least she will confirm here the rub.

  As for the late development, it can help to make a complete tear down and rebuild, as described in the second box of troubleshooting problems with iTunes for Windows updates. Excluding the iTunes folder of any AV real-time, tests can also help.

  Unless the site you develop is for the Asian market, I don't know why you want to use that particular font. The Basic, standard and digital alphabet punctuation glyphs has sans serif, Roman characters, but the rest is thousands of Kanji characters. While you can use the font .ttf and .otf and web fonts, it would be very unusual to use one so great. Pages should load quickly and 78 MB, with a value of faces to download for those who have connections slow Internet is not fast.

  I would take a different font without serifs. There are literally thousands who look identical or virtually identical to Yuanti.

  131 free and high quality without font serif to choose here. I'm sure you can find a desired.

• Why Developer edition of Firefox ask me to update?

  It isn't really a problem, but Firefox Developer Edition ask me to update to version 44.0a2, which I already

  What version of Firefox do need it?

  Do you need a stable version as the rejection, or even the beta version that will become the next version and get an update about twice a week?

  Or you don't mind updating daily with one using a generation night to test new (unfinished) features that will be part of a future version?

  The Nightly alpha1 channel sometimes gets a respin, and if you missed the first update then you will need to download the full version (45 MB).
  Editing (alpha2) does not get a respin because that only code that has relied on the Nightly channel for some land of week on the update channel, as well as the channel is a bit more stable.

  Our that it is always recommended to install the current version, or at least the beta if you decide to use one of the alpha versions, so you have a relief if certain Web sites or of any browser does not work.
