How to delight an engineer

July 29th, 2014

If you happen to work with engineers and they’re mostly unhappy with the way they’re being asked about potential projects, or if you’re an engineer in this very situation and your colleagues don’t seem to get it, here’s a simple how-to:

Step 1: Describe what the product or service is like when it’s finished, as precisely as you can, from A to Z. Put in the effort to sketch out the interface (if there is one), who does what in which particular order, who needs to know when something has happened, etc. Imagine how people will use it and what their expectations might be. Try to put yourself in every party’s shoes and walk through the whole thing. Think of legal constraints. Write everything down. (Use flowcharts whenever possible. Engineers love flowcharts.) Yep, that’s a lot, but believe me, it’s worth it.
Step 2: Define process boundaries. What is supposed to happen, what must not happen under any circumstance?
Step 3: Define development constraints. What is the budget? How much time is there to get this done?
Step 4: Have a meeting with the engineer(s) and give them all of what you have worked out so far, and they should be able to tell you what you need to know (can we do this in the quality proposed, considering all boundaries and constraints?) on the spot.

Bonus: How to delight engineers and non-engineers alike
Say Thank You, even if the answer you get is not what you were expecting.

Connecting to Avid ISIS 5000 on OS X 10.9

July 3rd, 2014

Though Avid doesn’t officially support this, it is entirely possible to connect your ISIS5000 < 4.6 using the respective ISIS client to your Mac on OS X 10.9, which currently only supports ISIS7000. Update: As of ISIS v4.6 this article is partially obsolete (see Avid KB).

To make it work, you need to have a Mac on which the ISIS client software that corresponds to your ISIS 5000 is installed. From there, copy the following items to a USB stick or network location, ideally you mimic the folder structure of your Mac HD in order to put everything in its appropriate place:

/Applications/AvidISIS (entire folder)
/Library/Application Support/Avid/AvidUnityISIS
/Library/StartupItems/AvidUnityISIS
/sbin/mount_AvidUnityISIS
(executable; use Cmd-Shift-G to go to folder)
/System/Library/Extensions/AvidUnityISIS.kext

Next, copy the files to your 10.9 machine’s system drive. You will need to enter admin credentials when modifying the /Library, /sbin, and /System folders.
Next, fire up Terminal to modify the permissions to certain files and folders, because those will very likely be “damaged” during the copying process off the original computer. You will need to enter your admin credentials when doing the following:

sudo chmod -R 0755 /System/Library/Extensions/AvidUnityISIS.kext
sudo chown -R root:wheel /System/Library/Extensions/AvidUnityISIS.kext

sudo chmod -R 0755 /sbin/mount_AvidUnityISIS
sudo chown -R root:wheel /sbin/mount_AvidUnityISIS

sudo chmod -R 0755 /Library/StartupItems/AvidUnityISIS
sudo chown -R root:wheel /Library/StartupItems/AvidUnityISIS

This will set the files and folders to the proper permissions. However, I strongly recommend verifying your permissions with Apple’s Disc Utility, because on one machine where I did this there was one admin user who couldn’t mount any of the ISIS workspaces (some error on the /Volumes folder), after repairing permissions everything was fine. And it is vital to perform these steps in this exact order, if you leave them out it won’t work.

Reboot your Mac, then you should be able to launch the ISIS client, and after properly setting up your connections you should be able to mount workspaces as usual.

Please keep in mind that this is a hack; Avid does not provide support for any problem that might occur because of this, neither do I. You’re doing this at your own risk. Make a backup copy before working on critical data or projects.
