Pi-hole project is a DNS sinkhole that compiles a blocklist of domains from multiple third-party sources. Pi-hole uses pi-hole-ftl AUR dnsmasq fork to seamlessly drop any and all requests for domains in its blocklist. Running it effectively deploys network-wide ad-blocking without the need to configure individual clients.

The package comes with an optional web and a CLI interfaces. Install the pi-hole-server AUR package. Data are collected and stored in two places:. For FTL configuration, see upstream documentation. Pi-hole has a very powerful, user friendly, but completely optional web interface. It allows not only to change settings, but analyse and visualise DNS queries performed by other devices.

Install php-sqlite php will be installed automatically and enable the relevant extensions detailed here:. Install lighttpd and php-cgi. Enable lighttpd. One must append the following to this file to ensure correct operation, noting that ip.

For more, see Issue To accomplish this, there are generally 2 methods to make it happen:. More information about making other devices use Pi-Hole can be found at upstream documentation. Install the pi-hole-standalone AUR package. The Pi-hole standalone package install a statically enabled timer and relative service will weekly update Pi-hole blacklisted servers list. If you do not like default timer timings from upstrem project you can, of course, edit it or preventing from being executed by masking it.

You need to manually start pi-hole-gravity.

Light from a scene passes through the aperture and projects an inverted image on the opposite side of the box, which is known as the camera obscura effect. The camera obscura or pinhole image is a natural optical phenomenon. Ibn al-Haytham —an Arab physicist also known as Alhazen, was the first to thoroughly study and describe the camera obscura effect.

Over the centuries others started to experiment with it, mainly in dark rooms with a small opening in shutters, mostly to study the nature of light and to safely watch solar eclipses.

Giambattista Della Porta wrote in in his Magia Naturalis about using a convex mirror to project the image onto paper and to use this as a drawing aid. However, about the same time, the use of a lens instead of a pinhole was introduced. In the 17th century, the camera obscura with a lens became a popular drawing aid that was further developed into a mobile device, first in a little tent and later in a box.

The photographic camera, as developed early in the 19th century, was basically an adaptation of the box-type camera obscura with a lens. The term "pin-hole" in the context of optics was found in James Ferguson's book Lectures on select subjects in mechanics, hydrostatics, pneumatics, and optics. The first known description of pinhole photography is found in the book The Stereoscope by Scottish inventor David Brewsterincluding the description of the idea as "a camera without lenses, and with only a pin-hole".

Sir William Crookes and William de Wiveleslie Abney were other early photographers to try the pinhole technique. According to inventor William Kennedy Dicksonthe first experiments directed at moving pictures by Thomas Edison and his researchers took place around and involved "microscopic pin-point photographs, placed on a cylindrical shell". The size of the cylinder corresponded with their phonograph cylinder as they wanted to combine the moving images with sound recordings.

Problems arose in recording clear pictures "with phenomenal speed" and the "coarseness" of the photographic emulsion when the pictures were enlarged. The microscopic pin-point photographs were soon abandoned. The camera that recorded the images, dubbed Kinetographwas fitted with a lens.

After he chose to continue his experiments with pinholes replacing the lenticular screen. The image of a pinhole camera may be projected onto a translucent screen for a real-time viewing used for safe observation of solar eclipses or to trace the image on paper. But it is more often used without a translucent screen for pinhole photography with photographic film or photographic paper placed on the surface opposite to the pinhole aperture.

A common use of pinhole photography is to capture the movement of the sun over a long period of time. This type of photography is called solargraphy. Pinhole photography is used for artistic reasons, but also for educational purposes to let pupils learn about, and experiment with, the basics of photography.

Pinhole cameras with CCDs charge-coupled devices are sometimes used for surveillance because they are difficult to detect. Related cameras, image forming devices, or developments from it include Franke's widefield pinhole camera, the pinspeck cameraand the pinhead mirror. Modern manufacturing has enabled the production of high quality pinhole lenses [7] that can be applied to digital cameras; allowing photographers and videographers to achieve the camera obscura effect.

Other special features can be built into pinhole cameras such as the ability to take double images by using multiple pinholes, or the ability to take pictures in cylindrical or spherical perspective by curving the film plane. Pinhole cameras can be handmade by the photographer for a particular purpose. In its simplest form, the photographic pinhole camera can consist of a light-tight box with a pinhole in one end, and a piece of film or photographic paper wedged or taped into the other end.

A flap of cardboard with a tape hinge can be used as a shutter.Note: This is a community provided and edited document. These instructions are not monitored by the Pi-hole development team.

Updated instructions: Installing dnscrypt-proxy 2. Please note that your Pi-hole will stop working during the installation so keep that in mind if there are other users on your network using the Pi-hole. Please note, I take no responsibility for any breakage or corruption of your Pi-hole installation when following this guide. This eases the creation of the service because now systemd takes care of creating the sockets, which avoids long shutdown times if a wrong pid was set etc see DNSCrypt-Proxy using systemd.

Recommended if you are not using your own server, any the remote server is logging your activity, and your client IP address is frequently changing. Not enabled by default because it may be slow, especially on non-Intel CPUs.

On some configurations the above "enable" command will create the individual sockets and define the services, but not actually enable the services. This will mainly occur if the default. To remediate, enable the various services individually:. Do this for all selected dnscrypt end-points. Afterwards reboot, or alternatively you can test immediately by also starting the services:. Run nslookup pi-hole. In case the server certificate get's updated it's important to have an up to date copy of the dnscrypt-resolvers.

Make no mistake: your support is absolutely vital to help keep us innovating! Last update: February 5, Pinhole glassesalso known as stenopeic glassesare eyeglasses with a series of pinhole-sized perforations filling an opaque sheet of plastic in place of each lens.

Similar to the workings of a pinhole cameraeach perforation allows only a very narrow beam of light to enter the eye which reduces the size of the circle of confusion on the retina and increases depth of field. In eyes with refractive errorthe result is often a sharper image. However, a second effect may appear at the common bridge between each two adjacent holes, whereby two different rays of light coming from the same object but each passing through a different hole are diffracted back toward the eye and onto different places on the retina.

This leads to double vision objects having doubled edges around the rim of each hole the eye is not focussing on, which can make the overall image disturbing and tiring to look at for prolonged periods of time.

Unlike conventional prescription glasses, pinhole glasses produce an image without the pincushion effect around the edges which makes straight lines appear curved. While pinhole glasses are claimed to be useful for people who are both near- and far-sighted, they are not recommended for people with over 6 diopters of myopia.

Additionally, pinhole glasses reduce brightness and peripheral vision[1] [2] and thus should not be used for driving or when operating machinery.

Merchants state that after prolonged use, the plastic grating should become easy to ignore. However, each time the user blinks, the horizontal lines of the grating will briefly appear to be thicker. This is because the eyelid moving over the pupil will reduce the amount of light falling onto the retina and thus will briefly remove the lateral inhibition effect which normally makes all the holes appear bigger and the grating appear thinner.

So, as long as the user keeps blinking, they will be constantly reminded of the dark grating covering their eyes. Pinhole glasses have been marketed by various companies on the claim that—combined with certain eye exercises —they could permanently improve eyesight. However, no scientific evidence has been found to support these claims. Due to a lack of formal clinical studies to substantiate this type of claim by companies selling pinhole glasses, this type of claim is no longer allowed to be made in the United States under the terms of a legal settlement with the Federal Trade Commission.

The pinhole occludera device used by ophthalmologists and optometrists for diagnosis of refractive errors, works on the same principles, but is not intended for use outside of diagnosis.

From Wikipedia, the free encyclopedia. The effect of pinhole glasses approximated by a camera.

A blurred eye chart, as would be seen by an individual with a refractive error. Pinhole glasses, when placed over the out of focus camera, make the chart somewhat readable once more. However, they darken the image and the grid blocks some of the finer details, requiring slight movements of the camera for the whole chart to be somewhat comfortably read.Many frequently Asked Questions and their answers can be found at our Discourse site.
