Keeping a log of the technical topics I am learning. These days those topics are centered around DeFi and Solidity programming. Absolutely not financial advice.
Following up from a previous blog post:
To violently remove a service from the Services window when uninstall fails, type at the command prompt:
sc delete "My Service"
I got to try Tossed recently, totally by chance.
If you’re on a particular diet, Tossed is absolutely perfect because it allows you to fine tune what you eat. This is something you usually can’t do with places like Pret-A-Manger, where sandwiches always come with bread and salads with pasta.
Chipotle is not bad because if you’re targeting a slow-card diet, you can eliminate the tortillas, have more beans, peppers, a bit of guacamole, some lettuce and a choice of 4 meats. But you get bored after a while.
So I was happy to try something different. Tossed give you the option to include / exclude a base (the carbs). And most of the base options are slow carbs: whole wheat couscous, brown rice or whole wheat noodles… Then you choose 1 of 9 meats, 1 of 12 delis and 3 of 23 veggies. The create your own page is here.
You can also go for a ready-made salad and swap ingredients.
And they have peanut butter smoothies!
By default Quartz.net creates a pool with 10 threads. How to change the size of the pool?
This is not obvious from the documentation, but burried inside one of the examples that come with the library:
NameValueCollection properties = new NameValueCollection(); properties["quartz.threadPool.threadCount"] = "1"; ISchedulerFactory sf = new StdSchedulerFactory(properties); IScheduler sched = sf.GetScheduler();
Why did I need to change the pool size to 1? Well my jobs are executing third-party .NET wrappers around some native code that is not exactly thread-safe. I had a situation where I couldn’t schedule the same job twice: on first execution the job would run fine on thread 1. On second execution the same job would start on thread 2 then hang on a 3rd party method call. Forcing both runs to happen on the same thread fixed the problem.

I was visiting Foyles the other day… Most books in the General Finance section have alarming-sounding titles. With the exception of a few books about Richard Branson or Warren Buffet it’s all about catastrophes, burns, falls, crashes, crunches, collisions, lies, delusions, failures, etc…
I’m not making this up, look at this list, all picked from the same bookshelf at Foyles:
Dark markets
How markets fail
When genius failed
When markets collide
When money dies
The end of money
How I caused the credit crunch
No one would listen
A decade of delusions
Masters of nothing
House of cards
Rigged money
Fool's gold
Devil's casino
Liar's poker
The wizard of lies
Biggest lies on wall street
...while brushing my teeth

Quoted from log4net documentation:
There are 2 different ways to enable internal debugging in log4net. These are listed below. The preferred method is to specify the log4net.Internal.Debug option in the application's config file.
Internal debugging can also be enabled by setting a value in the application's configuration file (not the log4net configuration file, unless the log4net config data is embedded in the application's config file). The log4net.Internal.Debug application setting must be set to the value true. For example:
<?xml version="1.0" encoding="utf-8" ?> <configuration> <appSettings> <add key="log4net.Internal.Debug" value="true"/> </appSettings> </configuration>This setting is read immediately on startup an will cause all internal debugging messages to be emitted.
To enable log4net's internal debug programmatically you need to set the log4net.Util.LogLog.InternalDebugging property to true. Obviously the sooner this is set the more debug will be produced.
Internal debugging messages are written to the console and to the System.Diagnostics.Trace system. If the application does not have a console the messages logged there will be lost. Note that an application can redirect the console stream by setting the System.Console.Out. The Trace system will by default send the message to an attached debugger (where the messages will appear in the output window). If the process does not have a debugger attached then the messages are sent to the system debugger. A utility like DebugView from http://www.sysinternals.com may be used to capture these messages.
As log4net internal debug messages are written to the System.Diagnostics.Trace system it is possible to redirect those messages to a local file. You can define a trace listener by adding the following to your application's .config file:
<configuration> ... <system.diagnostics> <trace autoflush="true"> <listeners> <add name="textWriterTraceListener" type="System.Diagnostics.TextWriterTraceListener" initializeData="C:\tmp\log4net.txt" /> </listeners> </trace> </system.diagnostics> ... </configuration>Make sure that the process running your application has permission to write to this file.
I’ve always thought privacy concerns over Facebook were exaggerated -they usually come from your parents who have been publishing their home address and phone number on the white pages for decades anyway. There is much much worse.
The mere act of voting in the UK ends up in having your home address published on the web.
If you registered to vote on the Electoral Roll and ticked the wrong box, the one with the confusing caption, something like “tick here if you don’t want your details to appear in the private listing”, then all your past addresses are on the web, year by year. Yippee!
It’s not just your home address, but also the list of people who lived with you. That must be the most blatant breach of privacy I’ve ever seen. It’s like Facebook for flatmates with privacy settings set to ‘Everyone’.
Look at this. Only the first part of the postcode is available. To get the full info all you have to do is register at 192.com.
