Windows 8 Windows-key shortcuts (via: Windows 8 productivity: Who moved my cheese?)

Posted by jpluimers on 2012/08/27

Brilliant post on using the Window-key for shortcuts with Windows 8 (all Windows 7 Windows-key shortcuts work, plus many more): Windows 8 productivity: Who moved my cheese? Oh, there it is. – Scott Hanselman.

Pricetracker/-watch/-drop alters/-history charts for Newegg.com, Amazon.com, Best Buy, BackCountry.com, Zzounds.com

Posted by jpluimers on 2012/08/06

Cool: sites that allow you to do track prices, get history charts, get alerts for price drops, etc. Got there through SSD prices in steady, substantial decline – The Tech Report.

Your account works at all of our price tracking sites:

And your account will work at any new sites we launch!

The SSD price drop together with the HDD Prices Not Expected to Decline Until 2014 makes me think: if/when I should finally ditch my RAID 5 storage server and build an ZFS server with server hybrid storage (which is totally different from desktop hybrid storage).

Many of the great references at Understanding how to use SSD as Hybrid Storage Pools for ZFS point to the old sun.com site, and suffer from link rot. A few I found back: Read the rest of this entry »

OpenVPN connect to the same LAN (bridged mode) (via: The VPN Menu — Endian UTM Appliance v2.4 documentation)

Posted by jpluimers on 2012/08/03

Another research item:

Need to provide access through OpenVPN to the same LAN as where the OpenVPN server runs on.

This is unusual, and requires a bridged OpenVPN solution.

Jürgen Schmidt wrote a nice article on this in 2008.

Endian community edition seems to support this out of the box:

Server configuration

In this panel you can enable the OpenVPN server and define in which zone it should run.

OpenVPN server enabled

Click this to make sure the OpenVPN server is started.

Bridged

If you want to run the OpenVPN server in one of the existing zones check this box. ..

note:

If the OpenVPN server is not bridged you must set the
firewall rules in the VPN firewall to make sure clients
can access any zone - unless you do not want them to.

VPN subnet

This option is only available if you disable bridged mode, which allows you to run the OpenVPN server in its own subnet that can be specified here.

Bridge to

If bridged mode has been selected here you can choose to which zone the OpenVPN server should be bridged.

Dynamic IP pool start address

The first possible IP address in the network of the selected zone that should be used for the OpenVPN clients.

Dynamic IP pool end address

The last possible IP address in the network of the selected zone that should be used for the OpenVPN clients.

Creating vSphere 5 ESXi embedded USB Stick (failed at first in HP XW6600, but with MBR partition table it works)

Posted by jpluimers on 2012/07/30

Installing and booting ESXi 5 from USB allows you to keep your storage exclusively for VMs and separately make backup of your boot configuration and data configuration (note you cannot put the DataStore on your USB stick).

A small stick (minimum 1 gigabyte) will suffice, and works on many systems, but at first not on my HP XW6600, despite the latest BIOS version 1.36a. You get a nice “Non-System disk or disk error” message.

Both methods I tried failed at first. I thought they failed because the BIOS on the HP has limited USB boot support. It did boot from single partition USB sticks, but seemed not to boot from multi-partition ones, no matter if they are removable or HDD (with the removable bit flipped).

The ESXi5 installer is a single partition one. The final ESXi5 installed image is a multi-partition one. That’s what got me thinking into the multi-partiton direction.

Since the problem is similar to the impossibility of booting VMware workstation VMs from USB stick, (this fails even from the BIOS), I tried Plop since Plop works for VMware Workstation. The Plop USB boot manager failed too. My final thought was to install Plop on a FAT formatted USB stick(which does boot) and continue from there to the ESXi5 one: that failed too.

Boy I was wrong: the failure was not caused by the multi-partition setup, but because of my “Google blindness”: I searched in the wrong direction with the wrong keywords, therefore not getting the right links as search results.

A VMware Communities forum threads on “No bootable device” after successful ESXI5 installation on Intel DG35EC desktop motherboard” and No boot after clean install  finally got me in the right direction:

As of ESXi5, the default partition table type is GPT (GUID Partition Table), not MBR (Master Boot Record) any more (thats why an ESXi4 install will work fine).

Booting from GPT is in the EFI standards (now in its second generation UEFI or United Extensible Firmware), allowing – among others – to boot from disks bigger than 2 terrabyte. You need a BIOS that is compatible with GPT to do so, and the HP XW6600 BIOS clearly isn’t compatible with GPT.

Not all is lost, as while installing ESXi5, you have an option – though well hidden – to force it to use MBR boot. That worked, and I will blog on the steps later.

The good news: it now works on my HP XW6600 workstations (that support both VT-x and VT-d, which means I can do PCI pass through).

How to create an ESXi5 install on a USB stick

First things first though: creating the USB stick in the first place. Read the rest of this entry »

Asus RT N66U: steps to get “Tomato Backup Settings & Log to USB Drive Script – TomatoUSB” working on an Asus RT N66U @AustinStAubin

Posted by jpluimers on 2012/07/27

Below are some steps to get the  Tomato Backup Settings & Log to USB Drive Script – TomatoUSB by Austin Saint Aubin working on an Asus RT N66U router.

I presume you are using a Windows system (hence the FAT/FAT32 formatting of the USB stick) for doing the edits and copying of files to an USB stick. Read the rest of this entry »

#WordPress changed from Alt-Shift to Alt #keyboard #shortcuts and now breaks your regular browser Alt shortcuts. @wordpressdotcom

Posted by jpluimers on 2012/07/23

A couple of months ago, I created a nice post listing all #WordPress Editor #keyboard #shortcuts for both Windows and Mac OS X.

As of a few days ago, WordPress.com changed their Alt-Shift shortcuts into Alt shortcuts.

For instance, Alt-Shift-d (strike through) is now Alt-d, thereby blocking the original Alt-d (which for most browsers on Windows brings you to the address bar).

They violate one of the basic GUI principles: keep existing keyboard shortcuts as they are.

On Windows based browsers that means: keep Alt and Ctrl based shortcuts. Alt-Shift, Ctrl-Shift and Ctrl-Alt-Shift shortcuts are OK.

I haven’t tested WordPress on my MacBook air yet (as I don’t think the end-users should be the WordPress.com beta testers, though they probably think the world at large is a big beta-test garden).

I have asked WordPress.com to change the shortcuts back to what they were.

Addendum to Guide to “Install Tomato firmware on Asus RT-N66U / RT-N16 / RT-N12 B1 / RT-N12 C1 / RT-N10U router 韌體教學 | Moonlight Knight”

Posted by jpluimers on 2012/07/23

I had a bit different experience getting the Tomato Shibby firmware loaded on one of my Asus RT-N66U routers than the description from Guide to Install Tomato firmware on Asus RT-N66U nor this Video of the Asus Routers Rescue Mode Tutorial.

Somehow, the Asus Firmware Restoration Utility kept indicating “The wireless router is not in rescue mode”, no matter what I did.

This might be due to that I run VMware Workstation with some virtual LAN adapters on most of my machines.

Or not: the web-interface on the Asus RT N66U would not get into the firmware restoration mode either.

This worked though:

  1. pull the power plug on the RT N66U
  2. press and hold the reset button
  3. insert the power plug on the RT N66U
  4. wait for the power led to slowly blink
  5. release the reset button
  6. wait a few minutes for the modem to become stable
  7. in the mean time set your PC to these IPv4 settings: – host = 192.168.1.100 – mask = 255.255.255.0
  8. start your web-browser
  9. point your web-browser to http://192.168.1.1 (it will time out, don’t worry)
  10. press the power button to turn off the router
  11. wait a few seconds
  12. press the power button to turn on the router now your router gets into rescue mode
  13. refresh your browser so it goes to http://192.168.1.1 again
  14. upload your Tomato firmware

Hollerith and why we have digraphs in Pascal and trigraphs in C/C++ (nostalgia, Apple ][ plus)

Posted by jpluimers on 2012/07/04

Apple ][ plus keyboardSome nostalgia (:

In the mid 80s, when programming in UCSD Pascal and Turbo Pascal, I learned that Pascal has (. and .) digraphs that translate into [ and ], similar to the (* and *) digraphs that translate to { and }.

In fact I thought the English word was bigraph (as bi- is a prefix for twice, just like tri- is a prefix for thirce).
The digraphs are lexical alternatives (Pascal ISO  standard 7185:1990 paragraph 6.1.9 or Extended Pascal ISO standard 10260:1990 paragraph 6.1.11). There is even one more: the @ at-sign is a lexical alternative for the ^ caret.

Back then (I was in my teens, there was no internet yet and school library had nothing on programming) I thought these were because keyboards like those of the Apple ][ plus couldn’t emit [ and ], but I was wrong: it was in fact the Hollerith Card Code that could not represent these characters.

That limitation was because of the first Pascal implementation was done on a CDC 6000 series that used punched card readers/writers.  You could not punch arbitrary numbers of holes on each row (lace cards lacked structural strength) limiting the character codes you can represent.

They still work in the Delphi compiler for arrays and for comments (I just learned that various Pascal implementations use different rules of mixing digraph and normal comments (some even allow nesting)).

While I taught myself C and C++ just as I taught myself Pascal, somehow I never learned that they use lexical alternatives too. It was only recently that they do, both as trigraphs and as of C99 also as digraphs and that there is even a trigraph tool as part of the C++ personality of RAD Studio 2007.

Visual Studio Smart Tag keyboard shortcuts: Ctrl-. and Shift+Alt-F10

Posted by jpluimers on 2012/07/04

I’m a keyboard fan, so recently I have put up a new Keyboards and Keyboard Shortcuts category and tried to add all old relevant posts to it (staying organized is time consuming, but in the end it pays back by being able to find back stuff faster).

At conferences, presentations, and clients people often wonder “how do you get to such-and-such IDE feature so quickly” and the answer usually is: be sure you know your keyboard shortcuts. Which isn’t easy, as documentation for them is often spread out, and to find the information: you have to know how the underlying actions are called.

A long time ago (I think it was in version 2005) Visual Studio introduced Smart Tags. Most posts talk only about one kind of Smart Tags, but the Visual Studio IDE has two kinds:

  • A tiny triangle in the designer
  • A combobox drop-down button like control in the code editor

Both listen to these keyboard shortcuts (most cheat sheets miss at least one of these, but you can find them at Pre-defined keyboard shortcuts and at the VS2008 C# keyboard cheatsheet):

  • Shift-Alt-F10
    The shortcut is called View.ShowSmartTag, View.ObjectBrowserGoToSearchCombo
  • Ctrl-.                    (yes, the . is a period)
    The shortcut seems to be called Edit.Generate

The pictures below show the Smart Tag in action.

           

Oh BTW: the red squiggly lines and some of the other adornments in the screenshot are from CodeRush, one of the most keyboard-centric additions to Visual Studio I know.

[Links] Asus RT-N66U (N900) dual-band router

Posted by jpluimers on 2012/06/08

Just came accross an interesting ethernet router: The Asus RT-N66U (N900) dual-band WiFi router.

It has quite a bit of horsepower, is passively cooled, might handle dual-WAN from the stock firmware, and it it doesn’t: it is supposed to run custom firmwares like Tomato, DD-WRT, OpenWRT, etc.

Interesting…
