Looking at these side-by-side randomly generated visualizations, neither of them seem substantively different from a distribution perspective. All to say, when generating a random color palette, there probably wasn't any need for me to use the Crypto module—I probably should have just stuck with Math. It's much faster and feels to be just as random. I'll leave the Crypto stuff to any client-side cryptography work (which I've never had to do).
From this benchmark, we are able to understand that Rust has consistent performance and is almost always faster than C# and Go. But that is to be expected as Rust runs on the metal. Between C# and Go the performance seems to be nuanced. As C# and Go seems to outperform each other in difference scenarios.

ACME V1 تا چند ماه دیگر به پایان خواهد رسید:In June of 2020 we will stop allowing new domains to validate via ACMEv1.
A simple Windows ACMEv2 client (WACS) Software version 2.1.3.671 (RELEASE, PLUGGABLE) IIS version 7.5 Running with administrator credentials Scheduled task not configured yet Please report issues at https://github.com/PKISharp/win-acme N: Create new certificate (simple for IIS) M: Create new certificate (full options) L: List scheduled renewals R: Renew scheduled S: Renew specific A: Renew *all* O: More options... Q: Quit Please choose from the menu: m Running in mode: Interactive, Advanced Please specify how the list of domain names that will be included in the certificate should be determined. If you choose for one of the "all bindings" options, the list will automatically be updated for future renewals to reflect the bindings at that time. 1: IIS 2: Manual input 3: CSR created by another program C: Abort How shall we determine the domain(s) to include in the certificate?: 1 Please select which website(s) should be scanned for host names. You may input one or more site identifiers (comma separated) to filter by those sites, or alternatively leave the input empty to scan *all* websites. 1: Default Web Site (2 bindings) Site identifier(s) or <ENTER> to choose all: 1 1: dotnettips.info (Site 1) 2: www.dotnettips.info (Site 1) You may either choose to include all listed bindings as host names in your certificate, or apply an additional filter. Different types of filters are available. 1: Pick specific bindings from the list 2: Pick bindings based on a search pattern 3: Pick bindings based on a regular expression 4: Pick *all* bindings How do you want to pick the bindings?: 4 1: dotnettips.info (Site 1) 2: www.dotnettips.info (Site 1) Please pick the most important host name from the list. This will be displayed to your users as the subject of the certificate. Common name: 2 1: dotnettips.info (Site 1) 2: www.dotnettips.info (Site 1) Continue with this selection? (y*/n) - yes Target generated using plugin IIS: www.dotnettips.info and 1 alternatives Suggested friendly name '[IIS] Default Web Site, (any host)', press <ENTER> to accept or type an alternative: <Enter> The ACME server will need to verify that you are the owner of the domain names that you are requesting the certificate for. This happens both during initial setup *and* for every future renewal. There are two main methods of doing so: answering specific http requests (http-01) or create specific dns records (dns-01). For wildcard domains the latter is the only option. Various additional plugins are available from https://github.com/PKISharp/win-acme/. 1: [http-01] Save verification files on (network) path 2: [http-01] Serve verification files from memory (recommended) 3: [http-01] Upload verification files via FTP(S) 4: [http-01] Upload verification files via SSH-FTP 5: [http-01] Upload verification files via WebDav 6: [dns-01] Create verification records manually (auto-renew not possible) 7: [dns-01] Create verification records with acme-dns (https://github.com/joohoi/acme-dns) 8: [dns-01] Create verification records with your own script 9: [tls-alpn-01] Answer TLS verification request from win-acme C: Abort How would you like prove ownership for the domain(s) in the certificate?: 2 After ownership of the domain(s) has been proven, we will create a Certificate Signing Request (CSR) to obtain the actual certificate. The CSR determines properties of the certificate like which (type of) key to use. If you are not sure what to pick here, RSA is the safe default. 1: Elliptic Curve key 2: RSA key What kind of private key should be used for the certificate?: 2 When we have the certificate, you can store in one or more ways to make it accessible to your applications. The Windows Certificate Store is the default location for IIS (unless you are managing a cluster of them). 1: IIS Central Certificate Store (.pfx per domain) 2: PEM encoded files (Apache, nginx, etc.) 3: Windows Certificate Store C: Abort How would you like to store the certificate?: 3 1: IIS Central Certificate Store (.pfx per domain) 2: PEM encoded files (Apache, nginx, etc.) 3: No additional storage steps required C: Abort Would you like to store it in another way too?: 3 With the certificate saved to the store(s) of your choice, you may choose one or more steps to update your applications, e.g. to configure the new thumbprint, or to update bindings. 1: Create or update https bindings in IIS 2: Create or update ftps bindings in IIS 3: Start external script or program 4: Do not run any (extra) installation steps Which installation step should run first?: 1 Use different site for installation? (y/n*) - no 1: Create or update ftps bindings in IIS 2: Start external script or program 3: Do not run any (extra) installation steps Add another installation step?: 3 Enter email(s) for notifications about problems and abuse (comma seperated): name@site.com Terms of service: C:\ProgramData\win-acme\acme-v02.api.letsencrypt.org\LE-SA-v1.2-November-15-2017.pdf Open in default application?

Did you know that DotVVM can be used to incrementally modernize old ASP.NET Web Forms applications and lift them to .NET Core? It is much easier than doing a full rewrite, and the application can be deployed at any time during the entire process.
a fresh re-write of the TypeScript Handbook is out of beta and is now our website’s primary resource for learning TypeScript!
Interview Question: What is the difference between “using directives” and “using block”
PGlite is a WASM (Webassembly) based TypeScript/JavaScript client library which helps to run PostgreSQL locally in Browser or in NodeJS / Bun. It does not include any dependencies. It is very light weight and it's size is 3 MB Gzipped. It supports many Postgres extensions like pgvector, live queries, bloom, btree, earthdistance, fuzzymatch and lot morebun.

} - The assembly discovery mechanism in type scanning has new methods to scan for “.exe” files as Assembly candidates. I had removed “.exe” file searching in 4.0 thinking that it was more problematic than helpful, then several users asked for it back.
- The assembly discovery handles the PrivateBinPath of the AppDomain in all (known) cases now
- Child container creation is thread safe now
GitHub License Checker
Adding a permissive license to your open source projects makes it easy for others to benefit from reusing your code. I typically recommend the MIT license for most projects because it’s simple, well understood, and allows the code to be used for essentially any purpose.
