Mac OS X: getting default route and ip addresses
Posted by jpluimers on 2015/11/30
On Mac OS X, bare route and ifconfig give way too much information to view the most important things at once.
So I used an alias for this:
route -n get default | grep 'gateway' && echo && ifconfig | grep '\: flags\|inet\|inet6'
Later I needed IPv6 support, so I changed it to:
netstat -nr | grep 'Internet\|Gateway\|default' && echo && ifconfig | grep '\: flags\|inet\|inet6'
So you get something like this:
Internet:
Destination Gateway Flags Refs Use Netif Expire
default 192.168.178.1 UGSc 23 0 en4
default 192.168.71.1 UGScI 7 0 en0
Internet6:
Destination Gateway Flags Netif Expire
default fe80::3631:c4ff:fe47:13f1%en0 UGc en0
lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 16384
inet6 ::1 prefixlen 128
inet 127.0.0.1 netmask 0xff000000
inet6 fe80::1%lo0 prefixlen 64 scopeid 0x1
gif0: flags=8010<POINTOPOINT,MULTICAST> mtu 1280
stf0: flags=0<> mtu 1280
en0: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 1500
inet6 fe80::6203:8ff:fea2:4814%en0 prefixlen 64 scopeid 0x4
inet 192.168.71.40 netmask 0xffffff00 broadcast 192.168.71.255

C# Settings reminder
Posted by jpluimers on 2015/11/26
As a reminder to self: Settings are nice (too bad they advertise them as Windows Forms Application Settings, as they are just as useful for other assemblies), but be aware…
When using Settings.Default, it will get the values to the state of the app.config (or defaults if there is no app.config) of the assembly that defined the settings, not the app.config of the starting process.
This is unless your settings are merged into the app.config of the starting process.

Solved: Android Play Store error 926 while downloading new apps
Posted by jpluimers on 2015/11/25
I had this a while ago on one of my Android devices: an error 926 while downloading apps from the Play Store.
After searching, the only relevant solution I could find is in the below youtube video. These are the steps to resolve the problem:
- Reset the “Download Manager”
- Go to “Settings”
- Click “Apps”
- Click “All” (it will often not show up under “Running”)
- Click “Download Manager”
- Click “Clear cache”
- Click “Clear data”
- Reboot your phone
- Reset the “Google Services Framework”
- Go to “Settings”
- Click “Apps”
- Click “All” (it will often not show up under “Running”)
- Click “Google Services Framework”
- Click “Clear cache”
- Click “Clear data”
- Reboot your phone
For some users, just resetting the “Download Manager” might fix the 926 problem. I had to reset “Google Services Framework” as well. Others had to reset the “Google Play Store” app.
These were the circumstances I encountered the 926 problem:
- Brand new device
- Added Google account
- Performed the first firmware updates
- Added some apps from the web based Google Play Store
- After successfully installing some apps, the device would show error 926
After fixing the 926 error, I installed all apps using the Google Play app which then went fine.

Raise specific exceptions like InvalidOperationException, not generic ones like ApplicationException.
Posted by jpluimers on 2015/11/25
Code Analysis in Visual Studio objects against using very generic exception types:
CA2201 Do not raise reserved exception types
‘BusinessClass<T>.StopProcessing()’ creates an exception of type ‘ApplicationException’, an exception type that is not sufficiently specific and should never be raised by user code. If this exception instance might be thrown, use a different exception type.
Company.Departement.Functionality BusinessClass.cs 157
Indeed ApplicationException and SystemException are bad (both mapping to also very generic COM HRESULT values COR_E_APPLICATION / -2146232832 / 0x80131600 and COR_E_SYSTEM / -2146233087 / 0x80131501).
Using InvalidOperationException is much nicer in this case. It still maps to a COM exception (in this case COR_E_INVALIDOPERATION / -2146233079 / 0x80131509).
