Apple’s new iPhone4 has created quite a stir, even though consumers are paying slightly more for the same phone with a slightly better display, dual (improved) cameras, and flash. I’m sure by now you know about the antenna problems and the lame way that apple chose to fix it, but I wanted one of these wonderful gadgets, so I signed up on the reservation list and finally got my email notification to pick one up this morning.
The Apple store was helpful as always, but as soon as I got the phone in my hands I realized that it was going to be another iPhone upgrade with a different goddamn dock. I tried the easy way out and wasted $9 on a “universal dock adapter kit”, which didn’t work at all with my Apple iPhone 3GS dock. I assumed it was meant for the dock that I owned, but this adapter was meant for some device which clearly didn’t match anything that Apple has ever produced. Nine dollars wasted and no working dock.
The dock is an essential device to me. Without it, I’d forget to drop my phone into the dock at work and keep it charged. How to fix this? Apple wants $29 for a new iPhone 4 dock. This is completely unacceptable to me, considering that the iPhone 3GS dock is now selling at $7 on many sites. Why pay again for a similar connector and janky audio-out contraption? (Did you know the audio out is provided by a microphone in the base of the dock, which connects to an amplifier and then the audio out jack? It does.)
There was only one way to fix this — time to make this right with some hacking.
So, out comes the dremel tool:
Let the hacking begin. We start with the 3gs dock, and go from this…
…to this, a few moments later. I hacked it into the shape of the 4g:
But guess what? Hacking the dock to fit the iPhone4 doesn’t work, because Apple’s modified the dock to only recognize the 3GS. If you connect an iPhone 4 to that very same connector, the phone and iTunes will not recognize the phone.
Sure, my 3gs still works, so I haven’t damaged anything:
Connecting the cable directly to the 4g works, just not the dock to the 4g through the very same cable.
Apple’s position on this is worsening. The iPhone 1g’s came with working docks. Then, they stopped supplying them. on the 2g and 3g models, it was an extra $20 and $25. Now it’s $29.
This is awful. There’s a custom plug that you can’t easily purchase, and all iPhone models, even though they use the same plug, are incompatible with each other’s docks because of artificial incompatibilities created by a series of resistor codes hidden inside the cable or device.
Thanks, Apple. I love the iPhone, but the way you’re treating your customers is bullshit.
This post is bit of a diversion for this blog, which is usually me babbling on about tech.
SXSW starts this Thursday, and I’ll be attending. You can catch me speaking on a funny panel called “How not to be a Douchebag at SXSW”, which Ed Huntsinger is hosting. But hey, it won’t be about tech. So maybe you won’t like that.
SXSW Interactive is great, but it’s like work to me; I always have to be on and make connections with people for work. Sometime around next Tuesday, the music portion of the event will start, and it’s a blissful mix of music, people, and madness.
I’ve spent the last couple of days or so going through the torrents for SXSW Music. 646 songs on the first one, and another 309 on the second torrent.
You can grab both of them here if you want to download them. They’re huge, but worth it.
As is the case with most submissions, about 90% of it is crap, but if you’re willing to sit through and listen to the music there’s a wealth of wonderful artists here.
Here’s my top 15 or so, in no particular oder
Allo Darlin- My Heart Is A Drummer
Something like the 60’s, yet reminiscent of Sing-Sing and some of the more country inspired 4AD artists.
ELEW – Mr. Brightside
Eric Lewis, AKA ELEW is a mindblowing pianist, playing what he likes to call Rockjazz on piano, He’s played TED, our own DNA Lounge. This is his cover of Mr. Brightside by the Killers.
The Golden Filter – Hide Me
Blissful, female vocal based, bouncy disco-electro perfect for the dancefloor.
The Heavenly States – Oui Camera Oui
A terrible recording with little to no dynamic range that reminded me of early Julian Cope.
Kill The Noise – All Too Vivid
I’d expect to hear this song at 1015 (a house club here in SF) at about 3:30 in the morning. Incessant, bouncing, house beat with heavily vocoded nothingness on top. Who just bought an access virus? You did, yes you did.
Lights – Saviour
This is what it would sound like if Canada tried to produce the LA Wall-of-sound pop sound. Female Vocals, Big, big bridges and choruses. Expect to hear this on MTV soon. I love this piece of pop aside from the minor Auto Tune glitches that exist all over it. Nice harmonies, but the lyrics? Forget it. It’s pop.
Luder – Sing to Me
I think I picked these guys because I’ve been on a strange metal bent lately (I blame Jack Black and too many late night PS3 sessions of Brutal Legend). Unfortunately this sounds like a goth band trying to complete for vocal bandwidth with slayer. It sort of works.
Maren Parusel – Dear Love
The likeness of Maren’s voice to Feist is what does it for me here. Breathy female vocals on a solid rock background with minimal rhythm guitar. A string quartet pops up unexpectedly to lift the chorus.
Margaret Cho – Eat Shit and Die
Can’t go wrong with Marget Cho.
Minipop – Precious
Minipop is the sort of breathy, reverb laden beauty that attracted me to bands like Love Spirals Downwards and whatever Project Records was vomiting up in the 90’s. The thing here, is that Minipop throws away all of those pretentious for perfect, blissed-out shoe gazer wonderfulness. I saw them at the Independent in SF last year and fell in love with them on the first listen. It helps that the singer is a 5′2″ elf-like creature. Loads of delay, lots of chorus. Love it.
Noush Skaugen – Run Baby Run
Guitars meet keyboards with a driving bass that reminds me of early Jesus and Mary Chain, but there’s far too many drums to really make the comparison hold true. The sort of music you’d want as the wind rips through your hair at 80mph down the highway.
Resplandor – Downfall
A reincarnation of Slowdive. Wall of guitars everywhere. I feel like I’m back in 1992. Excellent stuff.
Ruby Isle – So Damn High (Will Eastman Club Edit)
Big, giant kick drum and vocal samples everywhere. Electro at it’s most base.
Sex with Strangers – New City Anthem
Think first album Shiny Toy Guns with far less production and a bit of Human League thrown in for fun.
Sofia Talvik – Jonestown
Think Suzanne Vega and the Sundays coming together, without all that needless strumming of the 12-string. I won’t go to see her play at SXSW, but I’d listen to it with the lights out.
Hello! It’s 2010, a new year and I’ve got some speaking engagements coming up, where I’ll discuss Twitter operations and scaling.

Waiting for proposal approval, but probably will be similar to my talk at Chirp
Engadget recently featured an article describing YouTube’s blocking of 1080p content from select sites which allowed users to display the content on televisions instead of their computer monitors, or sites which utilized the YouTube API. Like the Hulu block last year, blocking the PS3 from watching shows, it marked another moment when television content producers failed to ‘get it’. Their understanding of content in the face of their own dying industry is poor and misguided.
The blocks on both services are easily removed through the use of a proxy that can replace the browser’s header in the outbound HTTP request.
I have both professional and personal experience in media convergence; Throughout my career I’ve worked for three companies that did streaming video, from adult content (Gamelink), to mainstream media and Independent film (Ifilm/Viacom). On a personal level, the flooding of my loft space has forced me into some temporary housing where I currently cannot not install Internet or Cable service, and I’m forced into using the slow (but not entirely awful) landlord provided WiFi.
Initially the WiFi service was a nightmare, but after the introduction of a pair of Meraki mesh access points, I was able to boost the signal to the point where the PS3 and laptops in the living room could access video. Meraki’s hardware has proven to be excellent under poor signal conditions and simple to use.
On the big Samsung TV that I own, this leaves me with a few options for video at home:
Hulu/Youtube via the PS3
The same, via laptop
Pay-to-play via the Playstation Store
Pay-to-play via iTunes
Basic Cable (no DVR, no channels, no time-shifting)
Most of these are great options (basic cable not withstanding). Laptop based options require me to connect cables, to lose the use of my laptop for the duration of the show, and because of the way the Mac supports full-screen websites, I can’t use fullscreen and the laptop’s screen at the same time. The PS3 is slow to download (although some of the best video I’ve seen on my TV), all Laptop options inconvenient (because of the cables)
It’s not about the technology either; We have the technology! It all works, just not as smoothly as the experience of loafing one’s self in front of the TV and pressing a couple buttons on a remote.
Content creators should be making every attempt to make it easier to consume their content, with advertising. There’s a duality here, where the online video world treats the laptop as a 1st class citizen and the TV as a second class citizen, and vice-versa when it comes to the Big Media world of Television.
All of this is about money — whom is paid and whom is not for the big business of the media world. The blocking needs to stop, and ad revenues shared between the content creators and the new distribution world of digital devices connected to large screens. There is fundamentally no difference between a large monitor, and the large flatscreen in front of my couch.
Here’s two scripts you can run if you have a 3G card, and a few friends stuck in the hotel room with you who want WiFi.
First, turn your laptop into an access point. These scripts work on MacOS X running 10.5.4 or better — good luck!
I call this script ‘make-me-an-access-point.sh’:
#!/bin/sh
#Edit your /etc/rc.conf to set the option firewall_enable to YES
# Edit your /etc/rc.firewall to add lines:
/usr/sbin/natd -dynamic -interface ppp0
sysctl -w net.inet.ip.forwarding=1
/sbin/ipfw -f flush
/sbin/ipfw add 1000 pass all from 127.0.0.1 to 127.0.0.1
/sbin/ipfw add 2000 divert natd ip from any to any via ppp0
/sbin/ipfw add 6500 pass all from any to any
ifconfig en1 192.168.1.1 up netmask 255.255.255.0 broadcast 192.168.0.255
dhcpd
and when you want this to go away, do:
laptop:bin jna$ cat undo-make-me-an-access-point.sh
#!/bin/sh
#
# undo the make-me-an-access-point script
#
sysctl -w net.inet.ip.forwarding=0
sudo /sbin/ipfw -f flush
sudo kill -9 `ps -efl | grep dhcp | egrep -v VMware | awk '{ print $2 }'`
echo "Now turn off the Airport, then wait a moment, and turn it back on."
The contents of my dhcpd.conf are very simple:
# dhcpd.conf
#
# Sample configuration file for ISC dhcpd
#
ddns-update-style ad-hoc;
# option definitions common to all supported networks...
option domain-name "retina.net";
option domain-name-servers 209.183.50.151;
default-lease-time 600;
max-lease-time 7200;
# If this DHCP server is the official DHCP server for the local
# network, the authoritative directive should be uncommented.
authoritative;
# Use this to send dhcp log messages to a different log file (you also
# have to hack syslog.conf to complete the redirection).
log-facility local7;
# No service will be given on this subnet, but declaring it helps the
# DHCP server to understand the network topology.
subnet 192.168.1.0 netmask 255.255.255.0 {
range 192.168.1.100 192.168.1.200;
option routers 192.168.1.1;
option domain-name-servers 206.13.28.12;
option broadcast-address 192.168.1.255;
}
Read that, perhaps while watching/listening toKevin Kelly’s riveting talk (from the TED EG conference) on the next 5000 days of the web (that’s right, we’re only 5000 days old) and the future of the Semantic web. Kelly says we’re building not a series of small machines on the Internet, but one gigantic thinking machine, approaching the connectivity level of the human mind.
Last Tuesday, I was part of the Velocity 2009 Keynote, where I gave a talk entitled, “Fixing Twitter”. I covered the last year or so of work in improving Twitter to deal with the massive traffic and user loads we’ve been under and how we use metrics to destroy the fail-whale.
Frequently you want to predict when things are going to happen, and if it’s not the end of the world, it might be something occurring a bit sooner, such as your disk filling up.
First capture some data, with cron. We’re going to capture the free space in our database, once a day, so we’ll put something like this in cron, and set it for every night at midnight:
Wait a few days. We were looking at daily file growth, so we waited a full week to collect data. We had the luxury at the time.
Now you’ll have a file with a series of ls entries in it. Run those through awk, and capture the sizes of the files.
cat /tmp/somefile_log | awk '{ print $5 }'
At this point, it’s time to fire up Mathematica. Mathematica is a stunning piece of software by Wolfram Research, used for data visualization, scientific work, and in a number of industries.
First, let’s load the data into Mathematica.
What we’re going to do now is to copy the 1st data point into the Fit, and create a function that will allow us to predict the future.
(* Fit data to a curve using a polynominal model, make sure you insert the 1st data point or the curve fit will be bad *)
result = Fit[data, {336660004864, x, x^2}, x]
(* current free space on our partition (312334824), refunding the 1st data point as that \
space is already alloc'd *)
diskfree = (312334824 * 1024) + Take[data, 1]
(* use the fit function to find doomsday *)
diskfreefunc = diskfree - result
(* when x = 0 , we are dead *)
deathday = NSolve[diskfreefunc == 0, x]
deathday = Take[x /. %, -1]
deathday = deathday[[1]]
DatePlus[datastartdate, N[deathday]]
So now we know when this data set will hit zero, we have the date of that failure, and an ability to graph when that will happen.
For this example, my data set turns into:
We now know that in ~64 days, we’ll run out of disk space. Prediction is pretty nice, huh?
For you stats types, you’ll want to know how good the fit is for this curve, and for that, we look at R2.
