Git: See my last commit – the forrest and the trees – Stack Overflow
Posted by jpluimers on 2016/05/25
There are so many ways to view the last Git commit on the command-line.
On the one hand this shows the versatility of Git. On the other hand there are so many trees in the forrest, that it is hard for people to find how to do simple things.
The one I like most is this:
git show --name-status --oneline
Others:
git log --name-status HEAD^..HEAD
git log -1
git show
git diff
git show --name-status
git log --stat -n 1

Delphi XE8 does not adhere the `$(PROJECTNAME)` in a “Unit Output Directory”, but does recognise `$(SanitizedProjectName)`…
Posted by jpluimers on 2016/05/24
The background here was a quick project at a client where many .dproj files were in the same directory, but they suffered from conditional define differences. Which meant that even if they were all using the DEBUG configuration, some defines in the .dproj directories were different therefore poisoning shared .DCU files (as Delphi does not automatically rebuild them when the sources have not changed even though the IDE switched to a new project).
There was no quick possibility to reorganise the project structure (a combination of a version system history being problematic and potentially lots of relative path references in the .dproj and .dpr files could still be broken) so I wanted different “Unit Output Directories” for each project preferably using non-hardcoded project name.
So I tried putting $(PROJECTNAME) in a “Unit Output Directory”. But unlike build-events – where that one has a value – in the Directory it hadn’t.
To cut things short, Uwe Raabe did some spelunking in the .dproj file and found that $(SanitizedProjectName) was recognised so I switched to .\$(Platform)\$(Config)\$(SanitizedProjectName).
Putting it in the OutputDirectory (where your .EXE gets emited) fails for most part. Yes, the .EXE gets put in the right directory. No, the debugger cannot find it as it thinks it needs to use %SanitizedProjectName%. No for TestInsight: it cannot find the EXE either because of the % expansion.
Based on SanitizedProjectName, I did some more spelunking coming with the below list. Remember though:
Only tested for
Win32applications for Delphi XE8
I assembled the list by doing a quick sed on a Delphi XE8 Win32 .dproj file transforming all XML element names to $() form then running it through a uniq like script. After that I added each of them in a “Unit Output Directory” prepended with .\_\ (well I cheated a bit, I did them in groups separated by a back-slash and went back to single items in case of failures. A kind of ‘binary search’).
Ensure the ones you use, are defined before you use them. For example: the definition of SanitizedProjectName need to be in the .dproj file before actually using SanitizedProjectName.
These expand to empty strings:

How can I get Win10_1511_1_English_x64.iso or Win10_1511_1_EnglishInternational_x64.iso ?
Posted by jpluimers on 2016/05/24
I now officially hate Microsoft download sites.
I’m trying to fix a friends PC where Windows 10 has screwed up (after he installed, it loads, but the screen turns black without a mouse cursor which indicates the video drivers are likely hosed). There is no F8 boot option in Windows 10 any more so I need media.
https://www.microsoft.com/en-us/software-download/windows10ISO redirects to https://www.microsoft.com/en-us/software-download/windows10 which forces you to download a “Media Creation Tool” that complains I don’t have 8 gigabyte free disk space.
I have. Just not on the C: drive freaking morons!
But https://www.microsoft.com/en-us/software-download/windows10 won’t let me download the ISOs.
Searching around, it looks like I need Win10_1511_1_English_x64.iso or Win10_1511_1_EnglishInternational_x64.iso
Does anyone know how to get them?

View Headers and Source from Outlook .msg file – via Super User
Posted by jpluimers on 2016/05/23
Sometimes people give you .msg files saved from Outlook instead of forwarding those mails by e-mail.
Opening a .msg file requires Outlook.
You don’t need to bind Outlook to an e-mail account for this (so you can skip those steps when asked the first time Outlook opens). An Office installation that includes Outlook suffices.
After opening the message:
- Open the toolbar if it’s not open yet
- Under “Move” choose “Actions” -> “Other Actions”
- Then choose either “Message Header” or “View Source”
For some HTML messages, “View Source” is not available. I’m not yet sure why.

“Unable to connect to the MKS”: the port 902 problem.
Posted by jpluimers on 2016/05/23
A message like “Unable to connect to the MKS” usually does not mean you have reached the maximum of 10 connections for a VM.
Usually it means there is some network issue, like a firewall or router misconfiguration.
Port 902 is used (both TCP and UDP) to provide (among others, hence MKS) console connections.
The default MKS port is 902, and you cannot change it.
For vCenter it is even worse as you cannot even go through NAT:
- nat – Connecting to vCenter Server, Unable to connect to the MKS: Failed to connect to server xxx.xxx.xxx.xxx:902 – Network Engineering Stack Exchange.
- Accessing VM Console – Error 902 – [H]ard|Forum.
About the only solution is to tunnel through SSH: VMWare vSphere Client Remote Access via SSH Tunnel and redirect ports 443, 902 and 903.

Multi-WAN routers compared
Posted by jpluimers on 2016/05/20
Mikrotik have statistics and way more features. Of the not so good features on the TP-LINK ER-5120 multi-WAN router (none of which are mentioned in their documentation), the worst 2 are:
- Virtual-Server table can only handle 32 incoming port redirects
- no IPv6 support
- both incoming WAN and outgoing NAT isn’t very stable (my guess it’s a NAT table filling up)

Less than two decades of Google Data Centers – from corkboard x86 hardware via GPU to TPU – now they make their own chips too
Posted by jpluimers on 2016/05/20
First corkboard production server by Google in 1998
Remember the image on the right? It was the first “corkboard” production server Google used in 1998 (it’s a museum piece now).
From there they were using commodity-class x86 server computers running customized versions of Linux for a “long” time which around 2005 even got their own 12V battery as UPS inside the machine and running 1160 machines in a 1AAA shipping container.
Later whey started using a mix of CPU and GPU increasing the performance per watt and recently went from 12V to 48V and even contributed 48V DC Data Center Rack to Open Compute.
In the mean time, Tensor Flow and AI got even more important for Google and during the Google I/O 2016 keynote, they revealed yet another step: TPU chips especially made for TensorFlow providing even better performance per watt for machine learning than GPU. The TPUs are not FPGAs (popular for instance when mining BitCoins), but ASICs that perform orders of magnitude better.
So in about 18 years, Google moved from cleverly assembled commodity hardware to highly specialised custom chips.
Exciting times are ahead of us. I’m really looking forward to the next steps.
