That will copy the first 90 minutes to output1.mp4. Adjust the timecodes and output file to write another chunk to a different file. There may be a way to do it by filesize, but I didn’t figure out how. As always use a recent version of ffmpeg if you can.
I got to walk down to the Hudson this morning and watch Shuttle Enterprise arrive in NYC. It was an amazing site to behold. It was cold, and the pier was pretty busy, but I think everyone had a great … Continue reading →
Some interesting graphs on iOS 5.1 upgrade stats. iOS 5.0.1 and 5.1 are notable because they are the first upgrades to be delivered OTA. Unless this data is a unique segment and not representative of the larger ecosystem (I don’t think that’s the case), this is pretty impressive.
This is why the upgrade process is so important to client side applications, especially when you manage a platform. After installation keeping a user running the latest and greatest is critical. It impacts your entire ecosystem, which in Apple’s case includes the web, iOS developers, tech support, and yes even wireless partners.
Google’s biggest mistake was leaving hardware vendors and wireless providers in charge of managing upgrades. They are carrying a lot of baggage from old Android devices that Apple doesn’t. This is only going to be more amplified in the next 12-24 months as Apple users stay more current and Android continues to fragment.
An old but interesting interview with X-Plane creator Austin Meyer on Direct3D vs. OpenGL:
…I bet on OpenGL, and used that. As a result, here we are, 15 years later, and the people that use Direct3D can support Windows only. But, with OpenGL, I support Windows, Mac, Linux, Palm OS, Google Android OS, and oh yes: iPhone and iPodOS which are also OpenGL. So having X-Plane in OpenGL let me move over to iPod and iPhone very quickly. The port was done in 2 weeks, to be very exact. And you saw that i have moved 500,000 units on the iPhone and iPod since. I get $7 from each of those sales, and have moved 500,000 units in the last year and a half, so get out your calculator, do some math, and see if i made the right choice to bet against Microsoft 15 years ago.
Always bet on standards. Nobody remains on top forever. When you bet on proprietary tech because it’s in the lead, you’re betting that your demise will happen prior to the leader falling. Never bet against yourself.
I was curious about Microsoft Flight, since it was released today. It’s not really a simulator like Microsoft Fight Simulator was. It’s really just an arcade style game but of higher production quality. The graphics are not bad, it runs smoothly, however there’s not much to keep you playing with it. 30 minutes in and already bored. I personally don’t find it entertaining or challenging.
X-Plane 10 on the other hand is mindbogglingly complicated and I suspect I will never even get “OK” at it, much less good.
It’s a shame Microsoft didn’t just spin off or sell the MSFS product to someone. I bet it could have done fine on it’s own. It seemed to have a pretty dedicated community around it.
Like many in my trade, I keep a Twitter client open all day. 140 characters works very well between compile times, reloads, uploads. I still use RSS extensively, but Twitter fills the gaps nicely as my brain is always looking for information to absorb (feel free to follow if you don’t).
To this day it amazes me that I can’t find a perfect Twitter client. Tweetie back in its day was pretty damn close, but since it was bought by Twitter, it went downhill to the point of being unusable on the iPhone. Amazingly priced at “free” it’s not worth the price. These days TweetBot is as close to perfect as I can find on the iPhone and I’d recommend it to anyone who is frustrated with Twitter for iPhone.
Largely due to neglect the Mac client is still usable to me, however it’s hardly awesome. Why doesn’t “command /” reliably bring the window to focus? Why can’t I set my preferred url shortener? The developer console has lots of weird select and focus issues. I could go on…
From where I sit, these are the most annoying things Twitter still hasn’t figured out:
Search Blows – This one everyone always complains about. Search isn’t good, and only goes a few days back. It’s a miserable experience.
Amnesia – Twitter has a very limited memory. You can only search a few days back. Your timeline can only go so far back. Even DM’s can only be retrieved a mystery period back. Everything eventually disappears. I actually backup my tweets to a MySQL database so I can search anything I’ve ever tweeted. Most don’t have this luxury. Perhaps they should just partner with Google and let Google handle their archive/search problem. Let Google pay for the data, and for the right to solve this problem.
DM Downgraded – This one is pretty specific to the new Twitter “Let’s Fly” UI. Direct Messages, are very obscured and buried. Yea I get it, you want everything out in the open. It’s annoying however to hide useful and sometimes important UI.
Incomplete Clients – There’s no interface that seems to do everything. If you want to know how many RT’s or Favorites posts have, the best UI seems to be the website. If you want to use a custom URL shortener, Twitter for iPhone has you covered. Twitter for Mac has no UI to show what client a tweet was created with, mobile with its limited screen size does. It also has no way to see RT stats for a tweet. Want to be notified when you have a mention or DM? iPhone or desktop client is best (that’s not the web clients fault). Amazingly these UI’s all come from the same company. Facebook (now) does a pretty good job on feature parody across web/mobile clients.
What are favorites/lists – I don’t think anyone has fully figured out what these really are and how they should be used. Is there a value to maintaining a list? It seems most use favorites as bookmarks to read later, some use it for marking tweets they really like. I know I’ve done both. Facebook hasn’t figured out lists completely either, though I feel they’ve at least given them a useful purpose for power users.
Spam – I think if a user signs up and just @replies a link to 50 people, an algorithm should be able to detect they are a spammer and stop it.
Placeholder – The thing that annoys me the most is they still haven’t figured out how to leave a placeholder on your timeline. Why can’t I just pickup where I left off? I need to search for it. Facebook never solved for this problem either. Amazon’s Kindle (and apps) solved for this brilliantly. Surely Twitter could adopt an API to solve for this. As someone who restarts their browser often due to work I’m doing, this makes the web UI unusable.
So what am I ignoring in terms of annoying Twitter client things?
I don’t understand this one. The reason many (most) sites require you to confirm your password is to ensure you typed it correctly when creating your password, otherwise a typo would prevent you from logging back in correctly later. We’ve all “fat fingered” a password before. That simple confirmation step prevents it on creation. How does entering my password twice when logging in provide any additional security? If the password is compromised, the extra field does nothing.
I presume the reason is to make Quicken look/feel more secure than it really is.
I should note that I like Quicken. I like it enough that even though the native Mac version is so disappointing on paper that I never purchased it, I did I purchased the Windows version and continue to use it there. I think that demonstrates my not hating Quicken. It does however have its quirks that just make me wonder what they were thinking.
