svn: E175013: Access to '/some/dir' forbidden

The below error would look like lack of permissions however permissions hadn't change neither the user desktop environment where credentials were saved:
svn: E175013: Access to '/some/dir' forbidden
Looking inside "auth/svn.simple/*" I found a password that I tried but did not work. Password was incorrect and the easiest way to correct the situation is to force to connect with the user again, password will be prompted and after supplying it the svn.simple/* file will get updated:
svn --username myuser mkdir http......

Microphone not working in Windows 7 guest running on Virtualbox (v4.3.16) from a MAC OS X (Mavericks) host?

Microphone not working in Windows 7 guest running on Virtualbox (v4.3.16) from a MAC OS X (Mavericks) host?

The very first thing you should do is to change the Audio Controller in VirtualBox. Below is a setting that worked for me:



Windows will complain about not finding a suitable audio driver but if you know that all you need is to install a "Realtek AC'97 Driver" for "Windows 7" then you will find http://www.ac97audiodriver.com

After installing the driver followed by a Windows restart you should be able to setup the microphone using the "configure/setup microphone wizard" options. If you get into troubles make sure "properties/advanced" show as default format "2 channels, 16 bit, 44100 Hz (cd quality)" as shown below:



I have read on the web the suggestion that this setting should match the host settings which you can set from the "Audio MIDI Setup" application. I have tried different combinations and it still works, the important thing is to rerun the setup microphone wizard to make sure distortion is kept to a minimum. In any case I left mine with the below settings:

Can we apply the 80-20 rule to find out the Minimal Marketable Feature?

Cam we apply the 80-20 rule ( "for many events, roughly 80% of the effects come from 20% of the causes" ) to find out the Minimal Marketable Feature (MMF)?

In my personal experience over bloated requirements as the norm. So I have the practice (even in my personal life) to analyze the root cause of problems to try to resolve as much as I can with the minimum possible effort. The 80-20 rule becomes my target and unless someone before me actually applied it I can say that in most cases at least I can present an option. Whether that is accepted or not depends on many other factors which I rather not discuss here.

Why this rule is useful in Software development is a well known subject. But making the whole team aware of it comes in handy when there is clear determination to be occupied 100% of the tine in producing value. If we can cut down to 20% the apparently needed requirements our productivity would literally skyrocket. Of course the earlier you do this analysis the better but be prepared because perhaps you, the software engineer will teach a lesson to everybody above when you demonstrate that what was asked is way more than what is needed to resolve the real need of the stakeholder.
