Syncing across multiple devices is difficult, so Apple conveniently ruled out the option of syncing your iTunes library on your phone or tablet with multiple Macs.
I have two Macs, which means I never used the option to sync my iTunes library with any of them. Better yet, it’s kept me from using iTunes at, all on my devices.
The reason I looked into this issue again, is that I really wanted to watch some WWDC videos on my iPhone during a commute. Sure enough, as soon as I added the videos to my iTunes library it popped up this notification. It tells me that it will erase all kinds of things from my phone and then sync with the iTunes library on this Mac, instead of my other one.
I did some searching online and figured out that you can actually manage your iTunes library manually 😱. The setting is very easy to find:
- Connect your phone.
- Open iTunes and select your phone.
- From the menu on the left, select ‘Summary’.
- Enable ‘Manually manage music and videos’.
After enabling this preference (on every device). You get a completely different interface to transfer music and videos to your phones and tablets. It doesn’t sync automatically (obviously), but if you have multiple Macs this works much better. 🎉
Most mechanical keyboards can be customized in various ways. The easiest alteration you can do is probably replacing the key caps with something that’s more your taste.
Instead of yanking out the original caps immediately, I laid out the new ones first. This made the process of putting them in smooth and easy.
Eye strain is a very real problem for anyone who works with computers on a daily basis. I wrote an answer to this question on Quora: “How can I protect my eyes as a software engineer?”.
As someone who writes software for a living, enjoys reading, playing video games and watching tv series, eye strain is something that I have to actively manage to avoid sore eyes, dizziness, headaches and feeling tired.
For me, the exercises that are described in some of the other answers aren’t sufficient. These are some of the things that I do that aide me in all but overcoming the issue.
Have your eyes tested. I’m very mildly myopic myself and have astigmatism in my left eye. Being myopic isn’t that bad; I can see perfectly fine without my glasses on, but astigmatism can make working with text on computer screens absolute hell.
Consider the picture below. My left eye sees everything like the bottom left quadrant. Glasses and contact lenses can easily overcome this.
Find alternatives to screen time
Your phone and tablet aren’t the best way to read articles or books. Get an e-reader instead. You’ll be surprised at how much more comfortable e-paper is to look at.
Find podcasts and audiobooks that you like. You can enjoy those even with your eyes closed.
I have a 1.5 hour commute and would spend much of that time glued to my phone. Getting a Kindle and subscribing to podcasts has reduced that time to near zero.
I try very hard not to grab my phone when I wake up or go to bed. The bright light feels especially hard on my eyes. I’ve also noticed that I feel more rested when I don’t spend an hour scrolling through 9GAG and Quora before going to sleep.
These are the things that help me avoid sore eyes. I’d love to hear any other tips. It’s getting harder to avoid looking at screens all day and I think we need all the help we can get to save ourselves from straining our eyes too much.
Figuring out what works and especially what doesn’t is a big part of building products. Whether you’re trying to figure out which feature to build or where to spend money on marketing, analytics can help you make those decisions.
If you’re building a web platform it’s relatively easy to setup Google Analytics (or something similar) to track a user’s behavior from the moment they hit your site until they decide to purchase your product.
If you’re building desktop apps, things get a little more complicated.
Through some experimenting and digging around in how OS X handles downloads, I’ve come up with a way to connect how a user hits your product’s site with the moment they open the app. This is incredibly useful.
By connecting the pre and post download path of a user you’ll be able to tell if a potential customer came to your site through that post on Facebook or that email campaign you sent out last week. All you have to do is append a
?ref/source/whatever=[name of your campaign]identifier to your download URL and then read that identifier from OS X’ QuarantineEventsV2 database.
That sounds a lot more complicated than it is. I’ve put a sample project on GitHub that shows how this works technically.
Full use case
Let’s say we’re building a Mac app and we just ran a marketing campaign through Facebook and send out a news letter. We’ve setup analytics in our Mac app in such a way that we can track app opens and some buttons clicks–the ‘Buy Now’ button specifically. We use specific landing pages (or URL parameters) that link to our website from the Facebook post and news letter.
The Facebook campaign and news letter link to the homepage, but both append some parameters to the URL: https://example.com/?source=facebook-campaign and https://example.com/?source=news-letter respectively.
We’ve setup our site and web server to ‘forward’ the
?source=parameter to the download URL. This means instead of just https://download.example.com/app.zip, the app’s download URL becomes https://download.example.com/app.zip?source=facebook-campaign (or ?source=news-letter).
Our app includes the code from the sample app, so we can retrieve the URL that was used to download the app. We can now do this:
- Mister X receives our news letter and clicks through to our website.
- Mister X likes what he sees and clicks the download button.
- Mister X launches the app.
- Mister X clicks around and uses the trial version of the app.
- After a few days Mister X buys the app.
Because the app registered where the app was downloaded, we know which campaign caused Mister X to download and ultimately buy the app. By comparing several downloads we should be able to determine which source was the most successful.
I would love to hear your thoughts on this approach. Let me know on Twitter: @boyvanamstel.
After soldering wires into my SEGA MegaDrive to be able to switch between PAL and NTSC, I did the same to my SNES. I never knew playing Mortal Kombat II and Super Street Fighter II Turbo could be this fluid.
Soldering was a little more difficult than the MegaDrive and MegaDrive 2 I did before, but nothing too troublesome. The guide over at mmmonkey is pretty easy to follow.
At the bottom of the guide they show a picture of a SNES where the RF output has been removed to make place for the region and PAL/NTSC switches. I decided to go the same route. Which made soldering on the switches a little harder, but check out how this looks:
Pretty clean and works great!
Just after I did the mod I noticed that nobody mentions how to remove the RF unit from the SNES, and I forgot to take pictures 🙈, but it’s pretty straight forward. If you turn over the motherboard you’ll notice four solder points right below the RF unit, desolder those and you should be able to just lift it off the motherboard.
- Shows where the RF unit used to be.
- Indicates the screw hole that I used to put the wires through.
I’ve put some isolation tape over the metal where the RF unit used to be and I’ve used the screw hole to put the wires through, pretty handy.
