Crystal (programming language) features and specs

  • Performance
    Crystal is designed to have the performance of C, thanks to its compilation to efficient native code. Its static type system and low-level memory management capabilities allow optimized execution.
  • Syntax
    Crystal offers a syntax that is heavily inspired by Ruby, making it intuitive and familiar for Ruby developers. This can significantly reduce the learning curve and improve developer productivity.
  • Type Inference
    Crystal provides powerful type inference, enabling developers to write less boilerplate code while still benefiting from the safety and performance of a statically-typed language.
  • Concurrency
    Crystal supports lightweight concurrency with fibers, which allows developers to write efficient and scalable concurrent programs with a simpler syntax compared to traditional threading models.
  • Community and Ecosystem
    Crystal has an active and growing community. It also boasts a rich ecosystem with libraries and tools, making it easier for developers to find resources and support.

Possible disadvantages of Crystal (programming language)

  • Maturity
    Crystal is still a relatively young language compared to more established languages like Python or Java. This can mean fewer resources, libraries, and tools, as well as potential instability in certain areas.
  • Compilation Time
    Crystal's compilation times can be slower compared to interpreted languages, particularly for larger codebases. This can impact development workflows and iteration speed.
  • Binary Size
    Compiled Crystal programs tend to generate larger binary sizes compared to other compiled languages like Go or Rust. This can be a consideration for resource-constrained environments.
  • Platform Support
    Being less mature, Crystal may have fewer options for platform-specific optimizations and integrations, which could limit its use in certain specialized applications.
  • Tooling
    Although the situation is improving, Crystal's tooling ecosystem is not as mature as those of older languages. This can affect the availability and quality of IDE support, debugging tools, and other development aids.

SDelete features and specs

  • Secure Deletion
    SDelete ensures that files are securely deleted by overwriting the data, making it extremely difficult to recover using standard data recovery tools.
  • Freeware
    Available at no cost, SDelete provides a powerful tool for secure deletion without the need for a commercial license.
  • Command-Line Utility
    SDelete can be operated from the command line, allowing for scripting and automation, which is particularly useful for advanced users and system administrators.
  • File and Free Space Management

  • Trusted Source
    Being part of the Sysinternals suite from Microsoft, SDelete is a trusted and reputable tool.

Possible disadvantages of SDelete

  • Complexity
    As a command-line tool, SDelete may not be user-friendly for individuals who are not comfortable using the command prompt or scripting.
  • Performance Impact
    Securely deleting files and wiping free space can be a time-consuming process, particularly on large disks, potentially impacting system performance during operation.
  • No Graphical Interface
    SDelete lacks a graphical user interface (GUI), which may deter less technical users from utilizing the tool.
  • Limited to Windows
    SDelete is designed specifically for Windows operating systems, limiting its usability for users on other platforms like macOS or Linux.
  • Potential for Misuse
    Given its powerful data destruction capabilities, there's a risk of accidental data loss if not used carefully, especially by inexperienced users.

  • Ruby for Good
    Which can include type assertions but also a lot more. The agents seem to do well with this. I've also had good results using agents to write Crystal https://crystal-lang.org/ which is Ruby-like but does have the static types and produces blazing fast static binaries. Might be a sweet spot for coding agents if you're building some backend services. But I'd still pick Ruby on Rails for a new full stack project. - Source: Hacker News / about 2 months ago

    Sounds a lot like Crystal, which is also similar to Ruby and features a green fiber runtime: https://crystal-lang.org/#concurrency. - Source: Hacker News / 2 months ago
  • A Grand Vision for Rust
    > 1. Go with a better type system. A compiled language, that has sum types, no-nil, and generics. I was looking for something like that and eventually found Crystal (https://crystal-lang.org) as a closest match: LLVM compiled, strong static typing with explicit nulls and very good type inference, stackfull coroutines, channels etc. - Source: Hacker News / 4 months ago

  • Keep your files safe. What can happen if you throw away a defective hard drive?
    What lessons can we take away from my story? They are, in fact, quite simple and obvious: merely deleting files and quick formatting is usually not enough when disposing of or selling hard drives. For more assurance, itโ€™s better to perform a full format (in modern operating systems, of course). And for the truly paranoid, thereโ€™s the good old console utility SDelete from the Sysinternals suite or a tool named... - Source: dev.to / over 2 years ago
  • Hyper V VM full disk, wonโ€™t boot
    I assume you were using a dynamically expanding disk - if so just note it won't dynamically contract just by deleting files. To shrink the drive you will likely need to run sdelete -z on the drive inside the VM to clear the free space, then edit and compact the VHDX. You will need to be able to boot the VM to run sdelete though so you'll need to temporarily move other files off the drive, or move the VM files to... Source: about 3 years ago
  • Does formatting a drive remove bitlocker encryption from formatted data?
    You can always download sdelete https://learn.microsoft.com/en-us/sysinternals/downloads/sdelete and do an overwrite pass just to be safe. It'll take a while but you can do other things while it's running. Source: about 3 years ago
  • Bitwarden backups
    My understanding is that it doesn't completely solve it. I don't have time to dig up an authoritative source for this claim โ€” hopefully this superuser comment will suffice. I believe that you can achieve something close to a secure erase by filling up your SSD to 100% capacity with data before deleting; the utility sdelete supposedly does this when using the -c option.
