The nerdy friday T-Shirt meme continues:

Chemists do it on the table …

periodically.

Hoping I never need it, but just in case:

Anyone who knows if there are equivalents for Mercurial/Hg?

Windows Kernel object names are optional. Don’t give them a name unless you intend them to be shared. (via: The Old New Thing)

Very interesting:

Kernel object names are optional. Don’t give them a name unless you intend them to be shared.

Scala programming language and Venkat Subramaniam videos

Posted by jpluimers on 2015/06/30

A long while ago, someone (it was too long ago, so I sincerely forgot who, it probably was in the JBuilder era) told me that I should try out Ruby and Scala.

I did take a short look at Ruby back then, but since Ruby was so focussed on Web Development, and my heart really wasn’t there, postponed it to the times that the Web would be hot for me.

Then I should have taken a look at Scala (which compiles to Java bytecode), but since I abandoned Java (JBuilder wasn’t nice, Java programming was slow and modern IDEs like IntelliJ IDEA and Eclipse weren’t there yet).

Now that I’ve done truckloads of work in the .NET and Delphi world (including domain specific languages and Pascal based products), I bumped into these Scala videos by Venkat Subramaniam:

Boy, I should have taken a look earlier: like Delphi and C# it is a statically typed compiled language, but it is on steroids.

Yes, I know it leans on the Java bytecode as a run-time platform, but so does the Android SDK as one of the Java Platforms. Contrary Ruby, which with IronRuby runs on .NET and RubyMotion runs Mac and iOS, Scala does not run on the .NET platform any more.

Given the witty way of presenting I’m surely going to follow Venkat Subramaniam and watch some of his other videos too.

Shortly after watching the above I bumped into this video by Steve Yegge (Google): Dynamic Languages Strike Back – YouTube.

YouTube: Some windows shortcut key hints (by Alister Christie)

Posted by jpluimers on 2015/06/29

I wrote quite a few entries about Keyboards and Keyboard Shortcuts.

But Alister Christie did something much better: he published a great video on YouTube: Some windows shortcut key hints.

Most of the examples he shows work in Windows 7 and up.

TinkerTry’s Xeon D-1540 fueled ESXi 6.0 home lab build begins LIVE! | TinkerTry IT @ Home

Posted by jpluimers on 2015/06/26

Interesting machine: TinkerTry’s Xeon D-1540 fueled ESXi 6.0 home lab build begins LIVE! | TinkerTry IT @ Home.

It does ECC and IPMI, fits mSATA, 2.5 drives, and 3.5 hot-swap bays. For more specs see Supermicro SuperServer mini-tower ordered with 64GB of memory for $1900 starts the ultimate 24×7 home virtualization lab | TinkerTry IT @ Home.

The drive trays used are these:

Besides the official ways of converting the 3.5″ tray for 2.5″ drives that only allows for 4 drives to be converted, I think there is an unofficial way that allows for more hot-swappable 2.5″ drives.

Converting the unofficial way

The case is an CSE-721TQ-250B. Looking at a picture of the dimensions of the space where the drive trays fit in (thanks Anandtech), removing the CSE-SAS-733TQ backplane and fitting these into the MCP-220-00075-0B should allow for 8 2.5″ drives to be connected:

(all found via Sata Rack Enclosure – on Aliexpress.com)

Converting the official way

Modify an existing 3.5″ tray to fit a 2.5″ drive: please note the drive is mounted up side down!

Note there is another (dual!) 2.5″ tray for a different kind servers: many 2U and some 4U rack mounted SuperMicro servers and chassises optionally have this in the back for boot drives:

These are for instance used in the below chassises and SAS extenders based on them (the extenders all use SFF-8644 HD mini-SAS3 cable connectors):

Note to self: if ever getting these, ensure to get them with PWS-920P-SQ or better power supplies as these are super quiet although the chassis fans can be loud which can be resolved with a PWM controller or carefully selecting the SuperMicro parts from Supermicro | Support | System Fan Matrix as described in Supermicro noise levels | ServeTheHome and ServeThe.Biz Forums.

“Invisible” T-Shirts & Hoodies by Reece Ward | Redbubble

Posted by jpluimers on 2015/06/26

Yet another T-Shirt friday one:

Invisible

Still wondering where the toolbox comes from, as it is not MacPaint nor a very early PhotoShop.

I think it is mimicked aft er the monochrome PhotoShop 2.5 edition.
