Lots of 2.5, 3.5 and 5.25 conversion brackets, cages and hot-swap bays

Posted by jpluimers on 2014/03/12

To get me some ideas on what is available on the market right now: ADATA, CORSAIR, CRUCIAL, PLEXTOR, SAMSUNG, INTEL & OCZ SSD (SG OFFICIAL DISTROS WTY).

For ZFS, this seems the controller of choice:

For high-density data,

For fast data:

Everything needs to fit in something like this HP XW6600. For Raid-Z3 you need many drives according to Raid Calculator | Raid Disk Space Utilization Calculator | ServeTheHomeSTH – Server and Workstation Reviews (as it can loose 3 drives: ZFS Raidz Performance, Capacity and Integrity Comparison @ Calomel.org) another calculator for risks: RAID Reliability Calculator – Simple MTTDL Model – ServeTheHomeSTH – Server and Workstation Reviews.

You can also use the below bays for instance for Finding Uses for Old 2.5″ Hard Drives | | Que.

A few remarks on 2.5inch disk solutions:

$120 Raspberry Pi Bundle with LCD Display, Expansion Boards, Cables, and Accessories (via: Jean-Luc Aufranc – Google+)

Posted by jpluimers on 2014/03/12

Jean-Luc Aufranc. is a great guy with lots of knowledge in the embedded world (read his resume).

I’ve been interested in Raspberry Pi experiments for a while now, so I was glad that today he pointed me to this very nice kit:

$120 Raspberry Pi Bundle with LCD Display, Expansion Boards, Cables, and Accessories

You can get it through DealExtreme, which I will do soon.

(I just saw how a guy is using a massive amount of Raspberry Pi and custom ASICs to mine for BitCoins)

CodeRage 8 replays – Embarcadero Technologies – YouTube

Posted by jpluimers on 2014/03/12

For my own link archive: CodeRage 8 replays – Embarcadero Technologies – YouTube.

Lots of nice sessions, including these REST sessions:

About the REST support in Delphi: make sure you take a look at the REST Debugger application, as you get full source code for it and is an excellent starting point to see how the REST components work together (it is written using the FireMonkey UI framework so it runs on a Mac as well as on Windows).

David I explains more about the REST Debugger here: Sip from the Firehose : Using the REST Debugger will help you prototype your Delphi and C++ REST apps.

Jim McKeeth has a really nice video about it as well on XE5 REST Debugger Supercharged | The Podcast at Delphi.org which describes how to use Delphi the Delphi REST tools to use KimonoLabs to scrape data from web sites:

History: run HD image with Borland’s Turbo Pascal 5.5/6.0/7.0 and Microsoft’s QuickPascal 1.0 in VMware Fusion

Posted by jpluimers on 2014/03/12

Edit 20250102: added various “[Wayback/Archive]” archival links, VMware information, amended TUWA location, and added alternative csboot.zip download location on the Internet Archive (the Wayback Machine download is broken and the original gone)

A really long time ago, I posted in [Wayback/Archive] history – What features contributed to the evolution of Pascal? – Programmers indicating there was a [Wayback/Archive] Hard Disk Image of MS-DOS 6.22 with Pascal for Computer Studies. In fact, that is an IMG file of a DOS hard disk. And this posts shows how to use it with VMware Fusion on Mac OS X. The is a hard disk image contains:

  • A full version of MS-DOS 6.22 (MSDN Original)
  • Borland Turbo Pascal 7.0 (main)
  • Borland Turbo Pascal 6.0
  • Borland Turbo Pascal 5.5
  • Microsoft QuickPascal 1.0

Edit 20250102: does not work under VMware Fusion when you run Apple Silicon. Not figured out a performant alternative yet. Will try figuring out later.

DOS on a Mac

.NET/C#/PowerShell: building .NET DiscUtils library for virtual disk images

Posted by jpluimers on 2014/03/11

Edit 20250107: added various [Wayback/Archive] archived links (dated as close to the blog post as possible) because of link-rot; marked some keywords as code; found the current .NET DiscUtils repository at [Wayback/Archive] GitHub – DiscUtils/DiscUtils: Utility libraries to interact with discs, filesystem formats and more where you also can download it.

 

.NET DiscUtils is an interesting open source .NET library for accessing and manipulating virtual disk images. Since it is entirely written in C# (without the need for P/Invoke), you should even be able to run this on non-Windows machines using mono. Later on, you will see the 0.11.0 build fails this, but it gives good hope it eventually will.

Virtual disk formats supported are DMG, ISO, RAW (IMG/IMA/VFD/FLP/BIF), VDI, VHD, VHDX, VMDK, and [Wayback/Archive] XVA, regular disks like Physical, iSCSI and NFS.

There are two ways of getting the .NET DiscUtils tools to run:

  1. [Wayback/Archive] download pre-build binaries (at the time of writing: version 0.10) from via [Wayback/Archive] .NET DiscUtils – Home, or
  2. from the [Wayback/Archive] latest source page, click the download button, then build the binaries from the source package. At the time of writing, that version is 0.11.

This post describes the second way, and requires PowerShell to be installed on your system (which probably is, as Windows 7 and Windows Server 2008 R2 include it). Read the rest of this entry »
