mcobrien··on Show HN: my new app is fast user switching for the iPad (sort-of)
I add an awesome bar and I have more stuff in the pipeline.

Atomic is a more complicated browser than Switch or Safari. It's a great app, but not for everyone.

mcobrien··on Show HN: my new app is fast user switching for the iPad (sort-of)
That's awesome feedback, thanks! I agree with pretty much everything - my plan is to have a lot more on the site (which is based on a theme I bought), but I also wanted to release early and iterate.

Sounds like I have some iterating to do, but it's nice to be busy :)

mcobrien··on Show HN: my new app is fast user switching for the iPad (sort-of)
I like the name but tbh it means nothing without a logo and it's obviously distracting so I've changed the site for now. How do you think it looks now?

I've thought about it -- it's not difficult to port iPad apps to other iOS devices -- I guess it depends on demand.

People are more likely to share iPads of course, but for hackers the other things you can use Switch for (juggling site logins, testing without cookies) are just as relevant on the iPhone.

I'm cringing. That was a mistake, fixed.

Thanks! You're right - the icon does need work. I wanted to avoid using a globe, but maybe clarity > everything.
mcobrien··on Show HN: my new app is fast user switching for the iPad (sort-of)
Thanks for the suggestions! I've changed the main heading on the page. I'll have to look into making the name more prominent too.

Here's the sort-of: it's a multi-user web browser rather than full fast-user switching but (at least for me), that's 90% the same thing.

It's implemented with some nice UI and cookie swapping.

mcobrien··on Re-entry to US without backscatter or pat-down
Don't talk to cops

mcobrien··on How I serve my site using only CloudFront, S3, and a few small tools
Wow, I hadn't checked Prgrmr's rates in a while. Their smallest is now $5 for 64MB of ram, and for $20 you get 1GB.

mcobrien··on U2's Natural Logarhythm: Exponential Decay in the Delay of The Edge's Guitar
Boy was U2's first album, so the sentence suggests Edge was using delay before he started recording U2 songs.
mcobrien··on The language I wish Go was
So many I wouldn't know where to start. Databases have had not-null constraints for years, but an accurate model often means having null values.

A better improvement would be to handle null references better - Rails' whiny_nil support is great for example.

mcobrien··on De-anonymizing LinkedIn profile views
Like you, I get nothing from it but I know salespeople who couldn't live without it. Want to get a meeting with someone at X corp? Try LinkedIn. That line went cold? Get back on LinkedIn and find someone else.

Great for finding prospects you don't really know, pointless for people you know anyway.

mcobrien··on SVG vs PNG
The embedded PNG is used for the scaled up "PNG side", the rest is SVG.
mcobrien··on Verizon iPhone is coming
Which was almost certainly price anchoring by Apple. If they leak to anyone, it's the WSJ.
mcobrien··on New Twitter Is About 50 Percent Rolled Out. Where’s The Facebook-Style Backlash?
It seems a good way to prevent backlash is to deploy over a period of weeks. Before I got newtwitter I mostly ignored what other people were saying about it. Now if I complain it's old news.
mcobrien··on Free, high-quality legal docs to get your startup started
This is good news for startups and I'm sure great for Goodwin Proctor. Nice to see the freemium model working in the legal profession.
mcobrien··on Most common words unique to 1-star and 5-star App Store reviews
This was a problem, but it was fixed with the release of iOS 4.0. Now users have to go to the app store to rate an app.
mcobrien··on Apple Relaxes iOS Restrictions On Development Tools, Publishes Review Guidelines
The rules and app store review guidelines are both protected by the developer NDA so no one's going to be eager to post them.

This mostly affects registered developers anyway (and I'd say there are a fair few on HN), for whom the rules are just a click away.

mcobrien··on Apple Relaxes iOS Restrictions On Development Tools, Publishes Review Guidelines
If you're a registered developer, you can read the just-published App Store Guidelines here:

http://developer.apple.com/appstore/resources/approval/guide...

For those who aren't registered developers, it's basically a list of 189 rules, most in the form of "Apps that ... will be rejected"

mcobrien··on How to set up your own private Git server on Linux
Daily, weekly and snapshot backups with Linode are $5 on top of what I'm paying them anyway (and just a few clicks to set up). That's less than the cost of GitHub's micro plan and I can have as many private repos as I want.

I love GitHub and I'm sure they'll continue to do well, but running your own Git server is only going to get easier. If you don't need the social side of what they offer, hosting yourself makes sense.

mcobrien··on New free monospace programming font by Mark Simonson: Anonymous Pro
Consolas is definitely my favourite. I switched over in Windows when I first saw it, and now use it in OSX too.

mcobrien··on In Search of (How We Perceive) Time
Perception of time is an extremely interesting area. One of my favourites was the cutaneous rabbit experiments (http://en.wikipedia.org/wiki/Cutaneous_rabbit_illusion), where researchers tap the arms of a blindfolded subject. They tap several times on the wrist, then several times on the elbow, but the sensation is of a sequence of taps leading up the forearm.

What's interesting is that the taps perceived as occurring in the mid-forearm occur before the elbow is tapped. Your brain goes back and alters previous memories based on subsequent events, without your awareness.

There is an intuitive sense that the memories you have of a particular time happened at that time, but research shows that's not always the case.

mcobrien··on Bill Gates Enrolls His Kids In Khan Academy
If the Khan Academy was new to you too, it's a giant library of training videos produced by one clever guy, Sal Khan. Subjects range from algebra to chemistry, finance and lots more. Looks great.

mcobrien··on Arcade Fire meets HTML5
Summary if it doesn't work or loads too slow:

* You wait for a couple of minutes, wondering if the progress indicator will ever move

* The song starts and a couple of windows open.

* Video plays of a guy in a hoody running down a street

* More windows open, showing your address panning and spinning around, using street view and google maps

* Flocks of birds and trees appear in the video and then street view images. If you look closely you can see the running guy in there too.

Pretty good, although the window tiling didn't work great for me. Worth a look.

mcobrien··on Arcade Fire meets HTML5
Yeah, mine actually centred on my old house. A little less glamourous than the rest of the video, but effective :)

Btw, it seemed to stall for me but eventually loaded after a couple of minutes (Chrome dev on MBP). Stick with it.

mcobrien··on O'Reilly $9.99 Exclusive Best of "Ebook Deal of the Day"
I don't know if they're exactly the same but I converted the Tapworthy one and it looked great as an ePub in iBooks on the iPad.
mcobrien··on O'Reilly $9.99 Exclusive Best of "Ebook Deal of the Day"
All O'Reilly's books are available cheaper if you have an iPhone (or maybe just iTunes?). Follow the guide here to extract the embedded ePub from one of their iPhone apps, which retail at $1.99 - $4.99. Scroll down to "Extracting an EPUB Pearl".

http://oreilly.com/ebooks/oreilly_iphone_tips.csp

btw, TapWorthy is well worth the $4.99.

mcobrien··on How to Take a Walk
I was with Tichy until I saw that link. Amazing work.
