Even though as of 12c R1, Oracle supports a row limiting clause, NHibernate 4.2 with Oracle.DataAccess.dll 2.112.3.0 does not support that.
When you let it generate the SQL for a LINQ Take call to limit the number of results, you get an exception like this (full exception and stack trace are below):
System.NotSupportedException was unhandled by user code
HResult=-2146233067
Message=Specified method is not supported.
The place where you Take is important, as this does fail:

Add these entries to your .vmx file:
MemTrimRate = "0"
sched.mem.pshare.enable = "FALSE"
prefvmx.useRecommendedLockedMemSize = "TRUE"
Works in VMware Fusion 5, 6, and 7. Probably 8 too.

Most typical Internet users will never see 1e100.net, but we picked a Googley name for it just in case (1e100 is scientific notation for 1 googol).

Mikrotik have statistics and way more features. The most lacking or disturbing features on the TP-LINK (none of which are mentioned in their documentation):
- The documentation mentions you can enable Enable Bandwidth Based Balance Routing then select the WAN connections to combine but that doesn’t work at all, even if you follow the bandwidth steps carefully.
- Balanced Routing work when you perform these steps as mentioned at time point 457 in this video https://youtu.be/YDUfP8a5zNY
- Enable Application Optimized Routing
- Enable Bandwidth Based Balance Routing
- Virtual-Server table can only handle 32 incoming port redirects; you get the message “Cannot add more than 32 Virtual Server entries” like in the picture below.
- No IPv6 support
- No way to show any statistics as graphs.
- Every once in a while the web interface becomes really really slow which only a reboot can resolve.
- You cannot have one of the WAN connections have multiple IP addresses.
- Local DHCP clients are not added to the DNS proxy which means you cannot resolve them by name.
- TCP Sequence Prediction: Difficulty=0 (Trivial joke)
- You cannot configure how often to check WAN connections
On the other hand: when you do balanced routing indeed bundles all the WAN connections, configured Virtual Servers do work well and WAN specific routing settings to what they need to.

Verdict: fine for home use, not good for real multi-WAN use.

After getting the pronunciation of bear wrong for the umpteenth time and searched for bear beer tear pear peer and more, I came across the below poem often wrongly attributed to George Bernard Shaw but in fact written by a Dutch guy: Gerard Nolst Trenité and called The Chaos.

Stefan Glienke worded it perfectly: Default(typeIdentifier) is a “magic” function that is implemented into the compiler and causes it to generate the correct code – like for records with managed fields it generates a call to FinalizeRecord and some instructions to zero the remaining fields.

When you have one app.config for your whole set of DTAP environments (develop/test/acceptance production), every once in a while you get this error:
ORA-12154: TNS:could not resolve the connect identifier specified
For this particular setup, it means the replacement of parameters in the app.config with actual values from the DTAP went wrong (or was missing). For that we’ve some steps in both the PreBuildEvent and PostBuildEvent of the .csproj file:
PreBuildEvent:
del "$(ProjectDir)$(TargetFileName).config"
copy "$(ProjectDir)app.config" "$(ProjectDir)$(TargetFileName).config"
PostBuildEvent:
powershell -noprofile -file Replace-Parameter.ps1 -Path "$(TargetDir)$(TargetFileName).config"
The PreBuildEvent looks like it is not needed, but sometimes Visual Studio forgets to perform the copy action.
