This command by default prints the SHA1 fingerprint of acertificate. If the -v option is specified, thecertificate is printed in human-readable format, with additionalinformation such as the owner, issuer, serial number, and anyextensions. If the -rfc option is specified,certificate contents are printed using the printable encodingformat, as defined by the Internet RFC1421 standard
Microsoft.Windows.Embedded.Standard.7.Runtime.x64-KOPiE Serial Key keygen
The entity that created the certificate is responsible forassigning it a serial number to distinguish it from othercertificates it issues. This information is used in numerous ways,for example when a certificate is revoked its serial number isplaced in a Certificate Revocation List (CRL).
The backbone of nearly all .NET serializers is reflection. Reflection is a great capability for certain scenarios, but not as the basis of high-performance cloud-native applications (which typically (de)serialize and process a lot of JSON documents). Reflection is a problem for startup, memory usage, and assembly trimming.
By default, the JSON source generator emits serialization logic for the given serializable types. This delivers higher performance than using the existing JsonSerializer methods by generating source code that uses Utf8JsonWriter directly. In short, source generators offer a way of giving you a different implementation at compile-time in order to make the runtime experience better.
The source generator can be configured to generate serialization logic for instances of the example JsonMessage type. Note that the class name JsonContext is arbitrary. You can use whichever class name you want for the generated source.
The source generator also emits type-metadata initialization logic that can benefit deserialization as well. To deserialize an instance of JsonMessage using pre-generated type metadata, you can do the following:
You can now (de)serialize IAsyncEnumerable JSON arrays with System.Text.Json.The following examples use streams as a representation of any async source of data. The source could be files on a local machine, or results from a database query or web service API call.
This example will deserialize elements on-demand and can be useful when consuming particularly large data streams. It only supports reading from root-level JSON arrays, although that could potentially be relaxed in the future based on feedback.
The existing DeserializeAsync method nominally supports IAsyncEnumerable, but within the confines of its non-streaming method signature. It must return the final result as a single value, as you can see in the following example.
In this example, the deserializer will have buffered all IAsyncEnumerable contents in memory before returning the deserialized object. This is because the deserializer needs to have consumed the entire JSON value before returning a result.
The writeable JSON DOM feature adds a new straightforward and high-performance programming model for System.Text.Json. This new API is attractive since it avoids needing strongly-typed serialization contracts, and the DOM is mutable as opposed to the existing JsonDocument type.
JsonSerializer (System.Text.Json) now supports the ability to ignore cycles when serializing an object graph. The ReferenceHandler.IgnoreCycles option has similar behavior as Newtonsoft.Json ReferenceLoopHandling.Ignore. One key difference is that the System.Text.Json implementation replaces reference loops with the null JSON token instead of ignoring the object reference.
A more-easily quantifiable change around sockets is dotnet/runtime#71090, which improves the performance of SocketAddress.Equals. A SocketAddress is the serialized form of an EndPoint, with a byte[] containing the sequence of bytes that represent the address. Its Equals method, used to determine whether to SocketAddress instances are the same, looped over that byte[] byte-by-byte. Not only is such code gratuitous when there are now helpers available like SequenceEqual for comparing spans, doing it byte-by-byte is also much less efficient than the vectorized implementation in SequenceEqual. Thus, this PR simply replaced the open-coded comparison loop with a call to SequenceEqual.
System.Text.Json was introduced in .NET Core 3.0, and has seen a significant amount of investment in each release since. .NET 7 is no exception. New features in .NET 7 include support for customizing contracts, polymorphic serialization, support for required members, support for DateOnly / TimeOnly, support for IAsyncEnumerable and JsonDocument in source generation, and support for configuring MaxDepth in JsonWriterOptions. However, there have also been new features specifically focused on performance, and other changes about improving performance of JSON handling in a variety of scenarios.
Another change to JsonSerializer came in dotnet/runtime#72510, which slightly improved the performance of serialization when using the source generator. The source generator emits helpers for performing the serialization/deserialization work, and these are then invoked by JsonSerializer via delegates (as part of abstracting away all the different implementation strategies for how to get and set members on the types being serialized and deserialized). Previously, these helpers were being emitted as static methods, which in turn meant that the delegates were being created to static methods. Delegates to instance methods are a bit faster to invoke than delegates to static methods, so this PR made a simple few-line change for the source generator to emit these as instance methods instead.
There have been multiple PRs in .NET 6 to improve the performance of different aspects of System.Text.Json. dotnet/runtime#46460 from @lezzi is a small but valuable change that avoids boxing every key in a dictionary with a value type TKey. dotnet/runtime#51367 from @devsko makes serializing DateTimes faster by reducing the cost of trimming off ending 0s. And dotnet/runtime#55350 from @CodeBlanch cleans up a bunch of stackalloc usage in the library, including changing a bunch of call sites from using a variable to instead using a constant, the latter of which the JIT can better optimize.
The impact of these improvements can be quite meaningful. aspnet/Benchmarks#1683 is a good example. It updates the ASP.NET implementation of the TechEmpower caching benchmark to use the JSON source generator. Previously, a significant portion of the time in that benchmark was being spent doing JSON serialization using JsonSerializer, making it a prime candidate. With the changes to use the source generator and benefit from the fast path implicitly being used, the benchmark gets 30% faster.
This is a free utility that is used for editing the registry to ensure the serial number descriptor of each FTDI device is ignored during driver installation. This feature ensures any FTDI device connected to a USB port is given the same COM port number.
FTD2XXST is an EEPROM serialiser and testing utility for FT232 and FT245 devices. FTD2XXST is based on our D2XX drivers and will work on Windows 98, ME, 2000 and XP platforms. The latest release supports the extra features of the FT232BM and FT245BM devices as well as the AM series devices.
Acrobat Professional and Standard are delivered as a single installer. Product behavior and features become enabled based on the entitlements granted by the licensing methodology (a user ID or serial number).
Admins who configure machines that have been purchased from vendors with Acrobat preinstalled may not be able to use a single image across multiple machines. This is true when vendors provide machines with unique retail activation serial numbers rather than a single volume licensing serial number
For example, in the past the Dell factory preinstalled Acrobat Standard with a volume licensing serial number. Dell is now providing Acrobat XI Standard via their cloud distribution method (Dell Digital Delivery) retail activation serial numbers. These machines cannot be used to create an image that can be used on other machines.
While processors are evolving to expose more fine-grained parallelism to the programmer, many existing applications have evolved either as serial codes or as coarse-grained parallel codes (for example, where the data is decomposed into regions processed in parallel, with sub-regions shared using MPI). In order to profit from any modern processor architecture, GPUs included, the first steps are to assess the application to identify the hotspots, determine whether they can be parallelized, and understand the relevant workloads both now and in the future.
The larger N is(that is, the greater the number of processors), the smaller the P/N fraction. It can be simpler to view N as a very large number, which essentially transforms the equation into \(S = 1/(1 - P)\). Now, if 3/4 of the running time of a sequential program is parallelized, the maximum speedup over serial code is 1 / (1 - 3/4) = 4.
Obtaining the right answer is clearly the principal goal of all computation. On parallel systems, it is possible to run into difficulties not typically found in traditional serial-oriented programming. These include threading issues, unexpected values due to the way floating-point values are computed, and challenges arising from differences in the way CPU and GPU processors operate. This chapter examines issues that can affect the correctness of returned data and points to appropriate solutions.
Because the default stream, stream 0, exhibits serializing behavior for work on the device (an operation in the default stream can begin only after all preceding calls in any stream have completed; and no subsequent operation in any stream can begin until it finishes), these functions can be used reliably for timing in the default stream.
However, if multiple addresses of a memory request map to the same memory bank, the accesses are serialized. The hardware splits a memory request that has bank conflicts into as many separate conflict-free requests as necessary, decreasing the effective bandwidth by a factor equal to the number of separate memory requests. The one exception here is when multiple threads in a warp address the same shared memory location, resulting in a broadcast. In this case, multiple broadcasts from different banks are coalesced into a single multicast from the requested shared memory locations to the threads. 2ff7e9595c
