Been awhile since I contributed any content to the wonderful Bushel team, so provided an article on accounting concepts that every small business owner should know.

As a small business owner, you need more than an intuitive feel for the performance of your business. Understanding a few basic Accounting 101 concepts goes a long way towards keeping the goals for your company in alignment with your performance.

What’s Coming Next, From The WWDC Keynote
Posted a Huffington Post article from my notes from the WWDC keynote. Hope you enjoy! Apple kicked off WWDC (World Wide Developers Conference) today, with a Keynote that showcased some of the upper tier of talent and management within Apple.

View System Information On An iOS Device
Under the hood on iOS is a hard place to get; especially without bricking or jailbreaking a device. There are a few tools that can provide insight into what’s on a device, and about the device, though. One is an app called SysSecInfo, available at https://www.sektioneins.de/en/blog/16-05-09-system-and-security-info.html. Once installed, you’ll see how much CPU and memory are in use, and not in use, on your device. Scroll down and tap on Process List to see a list of each process running on the device. Tap Details towards the bottom of the screen to see more information about the OS build running on the device. Overall, a handle little tool, with lots…

Block Specific iOS Versions From Accessing Exchange
Exchange Online and Exchange 2010-2016 can block a device from accessing ActiveSync using a policy. To do so, first grab a list of all operating systems you’d like to block. To do so, first check which ones are out there using the Get-ActiveSyncDevice command, and looking at devicetype, deviceos, and deviceuseragent. This can be found using the following command: Get-ActiveSyncDevice | select devicetype,deviceos,deviceuseragent The command will show each of the operating systems that have accessed the server, including the user agent. You can block access based on each of these. In the following command, we’ll block one that our server found that’s now out of date: New-ActiveSyncDeviceAccessRule -Characteristic DeviceOS -QueryString…

Precache Now Supports AppleTV
Precache, available at https://github.com/krypted/precache, is a script that populates the cache on an OS X Caching server for Apple updates. The initial release supported iOS. The script now also supports caching the latest update for an AppleTV. To use that, there’s no need to include an argument for AppleTV. Instead, you would simply run the script followed by the model identifier, as follows: sudo python precache.py AppleTV5,4

Automatically Cache Updates To Your OS X Server
A little while back, I did a little writeup on how the OS X Caching Server caches updates at https://krypted.com//mac-security/how-the-os-x-caching-server-caches-updates/. The goal was to reverse engineer parts of how it worked for a couple of different reasons. The first was to get updates for devices to cache to my caching server prior to 15 people coming in before it’s cached and having caching it down on their own. So here’s a little script I call precache. It’s a little script that can be used to cache available Apple updates into an OS X Server that is running the Caching Service. To use, run the script followed by the name of…

Run A Caching Server On A Computer Without Ethernet
I do a lot of testing on MacBook Airs and the latest MacBooks. Neither have a built-in Ethernet port and I try not to travel with one. But, when you enable the Caching Server service in OS X on a machine without an active Ethernet connection, the AssetCache will report an error of the following: Wireless portable computer not supported The cause is pretty obvious, but bypassable because of how the sanity check was built. Simply run the following: sudo serveradmin settings caching:Interface = en0 Now try again. Enjoy. PS: Since people always jump on the article where I talk about how to do things that shouldn’t be done in…
