Hdr Dynamic Vs Standard
Yolette Langevin
I'm trying to use a dynamic variable in a C# .net core app that's targeting .net standard 1.6. (platform? library? framework? meta-framework?) I first encountered this problem in a real application, but I have reduced it to a minimal reproduction.
A few systems (mostly very old, embedded, or otherwise specialized) do not support dynamic linking at all, but most developers are unlikely to care about those systems. On those systems, the linker will of course default to linking statically (unless whoever did the port screwed up :)).
On many systems (especially any typical Linux system), you probably have a utility called ldd. You can use ldd to check if it's dynamically linked to the standard library (assuming you know for sure what the library is called, it's usually libc though).
Most linkers prefer dynamic libraries to static when linking, but normally they have flags to explicitly specify the behaviour. It's definitely system dependent - check your linker documentation for details.
I have to represent the average and stadand deviation of the Lead Time deliveries in a graph for each supplier and product. And this average and standard deviation would change according to the slicer of the Purchase Order Date.
I tried to reply for the standard deviation P. The first formula has worked, and the I see the standard deviation of the product in the graph. But when I apply the second formula to filter per supplier, the result is zero.
Please refer to the attached PBIX file. When I captured the following screenshot, I put Material Code in the X axis. But later I found it should be Supplier instead, so I replaced the column in the PBIX directly without capturing a new screenshot as the settings are totally the same.
When you work with a record in dynamic mode, the order in which you set field values matters. For some developers, this aspect might feel constraining. It is likely that scripting in dynamic mode will require you to refer back to the UI often. For example, on an invoice in the UI, you would not set the Terms field before setting the Customer field. The reason is that as soon as you set the Customer field, the value of Terms will be overridden. On an invoice, the value of Terms is sourced from the terms specified on the Customer record. The same behavior happens in dynamic scripting. In your scripts, if you do not set field values in the order that they are sourced in the UI, some of the values you set could be overridden.
Standard mode is always used for user event scripts that instantiate records with the newRecord or oldRecord object provided by the script context. For that reason, the SSS_INVALID_API_USAGE error appears when a user event executes on one of these objects in the following situations:
When the user event script executes on an existing record or on a record being created through copying, and the script uses Record.setValue(options) on a field before using Record.getText(options) for the same field.
In dynamic mode, you can use Record.getText(options) without limitation but, in standard mode, limitations exist. In standard mode, you can use this method only in the following cases:
Be aware that the record.create(options), record.copy(options), record.load(options), and record.transform(options) methods work in standard mode by default. If you want these methods to work in dynamic mode, you must set the .isDynamic property for each method.
Standard-dynamic-range video (SDR video) is a video technology which represents light intensity based on the brightness, contrast and color characteristics and limitations of a cathode ray tube (CRT) display.[1] SDR video is able to represent a video or picture's colors with a maximum luminance around 100 cd/m2, a black level around 0.1 cd/m2 and Rec.709 / sRGB color gamut.[1][2] It uses the gamma curve as its electro-optical transfer function.[1][3]
The first CRT television sets were manufactured in 1934 and the first color CRT television sets were manufactured in 1954.[4][5] The term "standard-dynamic-range video" was adopted to distinguish SDR video from high-dynamic-range video (HDR video), a new technology that was developed in the 2010s to overcome SDR's limits.[1][6]
The linear part of the conventional gamma curve was used to limit camera noise in low light video but is no longer needed with high dynamic range (HDR) cameras.[8] An example of a conventional gamma curve would be Rec. 601:
In some cases the term SDR is also used with a meaning including the standard color gamut (i.e. Rec.709 / sRGB color primaries).[1] HDR uses wide color gamut (WCG) such as Rec. 2020 or DCI-P3 color primaries.[1][13]
The dynamic range that can be perceived by the human eye in a single image is around 14 stops.[10] SDR video with a conventional gamma curve and a bit depth of 8-bits per sample has a dynamic range of about 6 stops, assuming a luminance quantisation threshold of 5% is used.[10] A threshold of 5% is used in the paper (instead of the standard 2% threshold) to allow for the typical display being dimmer than ideal. Professional SDR video with a bit depth of 10-bits per sample has a dynamic range of about 10 stops.[10]
While conventional gamma curves are useful for low light and are compatible with CRT displays, they can only represent a limited dynamic range.[10][11] Standards require SDR to be viewed on a display with the same characteristics as a CRT (i.e. 100 nits peak brightness, gamma curve, Rec. 709 color primaries).[1][3] However, current displays are often far more capable than CRT's limits.[1] On such displays, higher brightness and wider color gamut can be displayed by adjusting and trying to enhance the SDR picture.[1] HDR is however required for the creative intents to be preserved.[1]
The campaign type is similar to traditional text ad campaigns, but with one main difference: there are no keywords. Instead, you target landing pages from your website. When someone searches Google with terms related closely to the titles and phrases that frequently appear within your targeted pages, Google will automatically match those queries to the content from your landing pages. Dynamic Search Ads will dynamically generate a tailored search ad, again using phrases and key terms from your page to create a clear, relevant headline for your ad.
There are a few different ways you can set up your targeting, for example targeting a group of URLs with targeting rules such as URL_Contains, or targeting specific URLs with URL_Equals or using Page Feeds.

Formerly, you could create dynamic search ads in any Google Ads ad group if the campaign was set up for dynamic search ads. Now, Google Ads has added a dynamic ad group that is dedicated to dynamic search ads. That is, a dynamic ad group can contain only dynamic search ads. The original, now known as standard ad group, still remains for other types of ads such as call-only ads and text ads.
I'm looking for a definitive answer on what port range "tcp/dynamic" and "udp/dynamic" uses. I would figure that it is 49152-65535, but I have not been able to locate anything in documentation or the community to confirm this.
This is due to the fact that any app-id can be made up of many different actual signatures, which all have different conditional criteria assigned to them. So looking at the App Store example downloading for instance will use a set signature and happen over dynamic ports, but browsing may happen over standard 443 and use a set signature for that identification.
One app-id doesn't necissarily mean only one signature is being utilized, and through conditional statements they can limit a signature to only identify under set ports listed within the app-id itself.
Thanks for the reply. If dynamic refered to all ports, that would not explain why many apps have specific ports listed, as well as tcp/udp dynamic. If dynamic covered all ports, it would be redundant to include others in the same app.
Since for each app some ports are explicitly listed and others are dynamic it makes me think that the dynamic range is a common range that an app could select a port from, such as 49152-65535. I believe that the app was observed using the specified ports each session, but different random port(s) established per session as well, from an upper-range that could be 49152-65535 or even 32768-61000.
I set up a test and found out a custom App-ID containing tcp/udp dynamic, and a signature looking for user-agents, will match on traffic on destination ports below 1024, 80 and 443 in this case. So it seems that dynamic refers to all ports. The question now is why the apps I mentioned specify specific ports AND a tcp/dynamic port reference at the same time, if dynamic means all ports? Doesn't make sense.
In our environment (OT, no Internet), we change Linux to use the IANA ephemeral range and only have modern OSes. We do not allow any systems to bind to the ephemeral range, so any listening services will always be below 49152 (and typically below 1024). We define Services for everything and do not allow the "application-default" or "any". One advantage to having narrowly defined Services is that there is no need to even allow the initial packet(s) required for PA to discover the App-ID and then block it; if the port isn't within the explicitly defined Service, it never is allowed. This is more work/overhead, but is the most secure approach. We only have 2 types of policy rules that have the ephemeral port range in use: those related to Microsoft Windows with App-IDs ms-wmi and msrpc-base (which list "dynamic" as their ports).
