Scanning: How to include a thin emulsion style edge during negative film scanning?

What I do is let the scanner (or its SW: use Vuescan) find the frame in the negative and then, just slightly increase the size of the frame, include part of the rebate (the unexposed edge of the negative). That is not hard to do.

(When I printed negs, I gave up with the object of the neg-arch headline and now I use the glass, which is a pain to put the film but, for the rest, much better).

Cocoa – When does it include a shipping button?

I am designing an application with some forms. I have seen other applications of Cocoa to see how they handle the sending of forms. Some applications do not have a send button and update their backup data store (or whatever) when, for example, a control loses focus or a window closes. Others, however, use a send button. Is there a rule or heuristic for when to use a send button and when not?

autofocus: why even high-end cameras still include normal (non-crossover) AF sensors?

Modern cameras often use two types of AF sensors: normal and cross type. While normal-type AF sensors struggle remarkably for concentrating on high-contrast vertical lines, cross-type sensors, while more sophisticated (and more costly in an appropriate manner), allow for an easier approach in that situation.

Due to the additional cost of including a large number of cross-type sensors, cheaper cameras often include only one sensor of this type at the central AF point, with mid-range cameras that often have a cluster around the center point and High-end cameras that have even more cross-type sensors in various configurations.

When analyzing the breakdown of some of the high-end cameras, even in a space where prices are well within four digits, there is still a decent amount of normal type AF sensors:

  • Both the Nikon D5 and the D850 have ~ 150 sensors, of which 99 are cross-type

  • The EOS 1DX mk II, the flagship of Canon, as well as its 5D mk IV, has 61 sensors with 41 crossed types

Taking into account that even in these very expensive emblematic and high-end models, about 1/3 of the AF sensors are of the normal type very consistent, I would like to know; Is this a purely economic design option or does the fact of having too many cross-type AF sensors create exponentially difficult technical obstacles?

Cheap or expensive brushes / Art suppliers

Cheap or expensive brushes / Art suppliers

+ Answer the thread

  1. Cheap or expensive brushes / Art suppliers

    In quality and price, the best watercolor brushes can vary from those in a sealed package of perhaps five, hanging at the end of the aisle of your national chain hobby shop to those that have a real stamp of approval as "By command, Her Majesty the Queen." (Famously, Queen Victoria ordered Winsor & Newton what would be her 7 favorite size in the series 7 of the red saber rounds Kolinsky). The first option could serve, for a short time, to clean a child's boots in his wardrobe. The latter could be framed with pride on the wall of your studio. In between, you will find a wide selection of more than just repairable brushes, of recognized fine brands. Some of these brands are: Winsor & Newton Series 7, Isabey, Rafael, Arches, Escoda, Pro Arte and others. The smaller lines, but still quite useful, include: Winsor & Newton Series 666, Princeton and Grumbacher. I recommend buying a good brand. Avoid the various gangue packages; they will perform so poorly in practice and in durability that they will feel very discouraged. I have some of each mentioned brand and I enjoy every brush. And yes, I bought cheappo brushes in the past … and I had to throw them away.

Should a commercial website include links to my social media accounts or show a feed?

Work in a business site for a client who does not sell your product / service online. They want to show that they have a social presence. They may have one or multiple. Is there any study that suggests that showing the sources in front of the buttons is the right way? I have a hunch, but I look for statistics with the client's meeting.

Thanks in advance!

error: function by parts to include the SawtoothWave function

I'm trying to write a function by parts that includes the SawtoothWave function. Can someone indicate how to do this, or if it is possible within mathematics?

The code by parts is here:

G = -1/50; (* Gradient of G *)
P = 6; (* pulse period in seconds *)

L = 3.08 / 2; (* pulse width in dimensionless units *)
tform = 1; (* time allowed for the soliton to be formed independently, for example, 100 *)

Bell[s_, x_] : = Exp[-(x/s)^2/2]

One step[x_, t_] : = -bell[1, x] Bell[10, t - 10] + A pieces[{{G SawtoothWave[{-1, 1}, x/L + t/P]}, t> tform}, 0]Encourage[Plot[Astep[x, t], {x, -10, 10}, PlotRange -> {{-10, 10}, {-0.05, 0.05}}], {t, 0, 50}, Execution of animation -> False]

The error message I receive is the following:

Accommodation: you need a recommendation for the course videos with piracy / download protection (could include a javascript video player or something else)

I'm really stuck in this case and would appreciate some help!

I am a creator of video courses and I need to protect the content of my video (which will be integrated into my website) so that it is not downloaded or shared on social networks.

At the same time, I am also looking for a place to host my videos (for free or on my own server, although I prefer a free third-party solution if possible). Naturally, the first thing that comes to mind is YouTube, but the problem is that the YouTube logo is shown in the video and can be clicked, which makes it easier to share the URL in Torrent sites, etc. ., even if I set video to "not listed".

I know that Wistia and Vimeo offer a premium solution, but I wonder if there is a free option out there that you may not know.

My requirements are: 1. Free video hosting 2. Foolproof protection of my video content The second requirement above can include a custom javascript web player (like Wistia's as seen here: https://wistia.com / support / embed-and-share / video-on-your-your website that makes it difficult to download the video, even looking at the source).

I am open to ideas.

Suggestions / recommendations / general thoughts?

Does the latest cumulative SharePoint 2013 update really include all previous cumulative updates?

When a cumulative update is published, it is assumed to contain all previous cumulative updates.

The size of KB 4022236 is 290.0 MB (August 14, 2018)

The size of KB 4092472 is 77.7 MB (December 11, 2018) in the download center and 3.7 MB (???) in the Windows update

Is the most recent cumulative update downloading all the old ones in the background?
That would explain why the size does not reflect the size of the previous ones.
