This server hosts mirrors for many Open Source projects. In particular it hosts many mirrors for popular linux distributions. This server is located in Erlangen, Germany. [More information about this server]
I gained confidence. Thanks to taking cold showers, I feel that almost none situation is stressful for me at all. I recommend you, my Dear Friend, to look deep in yourself, not via the mirror, but via the inner eye. If you do not know what I mean, start practicing intermittent fasting (I eat only between 7 p.m. and 12 p.m., avoid processed food and sugar), and take cold showers.
A mirror site is a website or set of files on a computer server that has been copied to another computer server so that the site or files are available from more than one place. A mirror site has its own URL, but is otherwise identical to the principal site. Load-balancing devices allow high-volume sites to scale easily, dividing the work between multiple mirror sites.
A mirror site is usually updated frequently to ensure it reflects the contents of the original site. In some cases, the original site may arrange for a mirror site at a larger location with a higher speed connection and, perhaps, a closer proximity to a large audience.
Can anybody tell from the specs or other sources how's 6D's mirror regarding M42 lenses and the mirror hitting the lens rear? IIRC, 5D Mk III's mirror is somewhat smaller than 5D's and 5D Mk II's. Is that correct?
Not sure about mirror size - but, in any case, I doubt there will be any issue. It was my understanding that M42 flange depth is greater, and, as it was designed for full-frame 35mm SLR's, there would be very little chance of any issues. I've had none with my 5D3.
Thanks. I know there's no problem regarding the flange length and only a non-lens adapter is needed. But some M42s do actually protrude so deep in the camera body that with 5D and 5D Mk II there has been reported cases of the mirror hitting the lens. Hence the question.
On thin adapters that allow infinity focus, there are definitely M42 lenses that the mirror of the 5DMkII hits. If the 5DMkIII and 6D have the same spec that the 5DMkII has, which is very likely, those lenses will be an issue if not modified. I filed material off of my problem lens (Auto Takumar 35f/3.5), because I have no intention of ever selling it. I had to file the material off to use the lens with the 1DsMkII and even more material to use the lens with the 5DMkII. The lens worked fine on crop bodies without modification. Smaller mirror.
It's fairly obvious when it happens. I can feel it, and hear it. It sounds like the shutter is real slow, but it's the mirror stalling on the rear end of the lens. Near infinity the mirror might pass with a minor stall, but at infinity it can actually get stuck there, and the lens has to be focused to a shorter distance in order for the mirror to slap back into place. My 50f/1.4 is no problem. I want to say wide angle lenses are the culprits, but I don't have anything wider than the 35f/3.5, so that would be pure speculation. A larger aperture 35mm lens might work as well.
When word of this first came out from 5D users, there were cases in which mirrors were chipping because users didn't know it was happening. Ouch!! I was aware it was possible because of those reports, so first sign of anything unusual, and I had the lens off. Initially I used a home made paper gasket of card stock to shim the lens out, but that was too fiddly, so I got out the file and did the permanent fix. That's my story, and I'm sticking to it.

As I mentioned, the distro uses the official repositories so for our location we can make use of some closest mirrors here I leave a list of them, to add these repositories we must edit the sources.list
2.- Before installing the intel or amd microcode, you need to install console-setup or, failing that, install it from the hardware application deepin drivers as well as those of the graphics card, since there comes a modified graphics driver by deepin and brings less problems than the most current and official.
Mirrors with status "partial" is when sync has been completed with errors (often from tmp files or dirs which we do not have permission to read on the source). Mirrors with a bold status are deemed out of date by us (thresholds for this range for each mirror).
An important methodology to overcome tissue-induced aberrations is the use of intensity-based adaptive optics (AO), which uses a deformable mirror in the emission path to compensate for wave-front distortions. The required shape of the mirror can be found by iteratively optimizing the contrast of the image (or guide star when possible)10. However, in SMLM the acquisitions are noisy and contain a strongly fluctuating amount of signal photons, rendering traditional approaches unusable. Various SMLM-specific AO-methods have been proposed to overcome these issues11,12,13, but the exact performance of these different AO-methods has not been consistently demonstrated and it has remained unclear what level of aberrations these methods can correct and under which conditions.
In order to ensure accurate modulation of the Zernike modes, the deformable mirror needs to be properly calibrated. The DM was calibrated by replacing the camera with a Shack-Hartmann sensor (HASO, Imagine Optics) to directly measure the wave-front, using the provided software. A 1-μm bead (TetraSpeck, ThermoFisher, T7282, dilution 1:1000) dried on a coverslip and mounted in glycerol was used as a point source. Mounting in glycerol reduces apodization in the pupil plane caused by super-critical angle fluorescence, ensuring a homogeneously filled pupil. We blocked other beads in the FOV by placing an iris in the intermediate image plane. The wave-front deformation of each actuator was measured with 10 push-pull cycles to obtain the interaction matrix, which was then converted into the Zernike-based control matrix. We perform this calibration once a year.

Adding most up-to-date mirror list in your Arch Linux is one of the recommended thing you should do. This is because, If you add most updated mirror list, you could easily avoid slow download rate, and error messages while installing, and updating packages. As you see in the /etc/pacman.d/mirrorlist file in Arch Linux, you might have noticed that there are only one mirror server per country. However, there should be more than just one server per country, but the mirror list file will display only one. So, how do you add or retrieve the latest and updated mirror list of your choice in Arch Linux? No worries. This is whereReflector comes in handy.
The test was performed with 32 stainless steel and molybdenum mirrors placed in pan-pipe shaped cassettes and exposed in JET in the divertor and on the main chamber wall for 127000 s including 97000 s of X-point operation. Surface composition and total reflectivity were determined afterwards All mirrors. from the divertor were coated with deuterated carbon deposits causing the reflectivity loss by a factor of 6-10 in the visible range. Flaking and exfoliation of deposits were observed in some cases On the main. chamber wall the deposition occurred mainly on mirrors located deep in cassette channels whereas mirrors close to the channels entrances were free from deposits and retained fair reflectivity (similar to 90% of initial value) especially in the infra-red range. No significant differences in behaviour of steel and molybdenum were noted. The need for development of methods for mirror cleaning and/or protection in a reactor-class device is addressed.
