JSadowski··on Open-Source GPU Architecture from the University of Wisconsin-Madison
UWM = University of Wisconsin Milwaukee.

The University of Wisconsin Madison is referred to as UW, "Wisconsin", or The University of Wisconsin -- but not UWM.

JSadowski··on Show HN: Potbox – A premium cannabis subscription club
I recall news stories about legal pot businesses in Washington not being able to keep their money in banks because of federal regulations, so I'm curious how they're able to take credit card payments. Is it different for medical marijuana? (I wouldn't think so, as that is still illegal federally).
JSadowski··on Gbatteries (YC W14) Launches BatteryBox, A 50Whr Backup Battery For MacBooks
Good point, I didn't think to check the capacity of the Air's internal battery.
JSadowski··on Gbatteries (YC W14) Launches BatteryBox, A 50Whr Backup Battery For MacBooks
They claim that their 50 Whr battery can power a MacBook Pro for 6 hours, a MacBook Air for 12 hrs. By my math, that would mean that the MacBook Pro would only be consuming an average of around 8.3 watts an hour, the air only around 4.2 watts an hour.

That seems absurd to me, considering the power supplies that ship with the MacBook Pro and the MacBook Air are 85-watt and 45-watt respectively. They are assuming that each only draws about 10% of the power that the official power supplies are rated at. Anyone have a Kill-A-Watt to see the actual draw of their device?

JSadowski··on Fake Name Generator
People have a UPS tracking number?
JSadowski··on Supreme Court to Hear Aereo Case
The thing that always annoyed me about Aereo is how they restrict who can "rent an antenna". If they are to stick to their legal argument that they're just renting an antenna, then why can I not rent an antenna based in New York City, even though I live in Wisconsin?
JSadowski··on Google to reject Chrome extensions outside of Chrome Web Store
Who decides who gets to be a CA for SSL certs? Similar process. Somehow my browser doesn't recognize a CA that would allow any random person to pretend to be Facebook.
JSadowski··on MacBook Air Flash Storage Drive Replacement Program
Yes... swap the two drives. The optical bay cannot properly put the HDD to sleep. I am running a similar setup, but with the HDD in the original bay, and the SSD in the optical bay and have no issues.
JSadowski··on AppleTV 6.0 requires Fairplay-DRM Airplay Sources
I'm successfully pushing local content to my Chromecast. The developer in question was using an undocumented API. If you use the documented APIs, things work just fine.
JSadowski··on Twilio Announces MMS Support
Sadly, it doesn't look like they support group messaging. That would be a killer feature.
JSadowski··on Chromecast update breaks AllCast
Sure... I'll throw up a gist... not the correct way to do it, crappy sender UI, based on early code examples from Google, but it works:

https://gist.github.com/jonathansadowski/6345103

Feel free to use / copy / fork, whatever. Basically, you can send any URL to the receiver, and the receiver then loads that URL in its video element.... that URL can be local, remote, whatever... requires that you have a webserver to serve your local content.

JSadowski··on Chromecast update breaks AllCast
I've been using my Chromecast to play local content since day one. Then again, I have a whitelisted application that I'm using and I'm not distributing it. There is nothing really stopping developers from developing such services... local content plays fine. Google just doesn't want you distributing them until the dust settles and they lock down their API. If it takes them more than a month or so to do so, or if they then prohibit such uses of the Chromecast, then maybe you have a story, but until then -- geez.
JSadowski··on This coupon code is a slap in the face
I'd be curious to test something like this: http://jsfiddle.net/CLJYC/

"Do you have a gift card or promotional code?" Y/N, and then only show the field if yes is selected.

JSadowski··on Stop asking users for their timezone – use per-device settings and JavaScript
Because zip codes do not equate to cities 1 to 1. Many cities have multiple zip codes, and some zip codes span multiple cities.

Zip codes are based on postal routes, cities are not.

JSadowski··on Stop asking users for their timezone – use per-device settings and JavaScript
OSX doesn't use IP geolocation to determine location... they use wifi triangulation. VPN connection-state shouldn't make a difference one way or another.

JSadowski··on #FF4A00
You're correct in pointing out that the odds of #FF4A00 being selected randomly are the same as the odds of #EAF7C2 being selected randomly; just as the odds of the Powerball numbers 1 2 3 4 5 P6 being selected randomly are just the same as the odds of the Powerball numbers 1 36 40 52 53 P20 being selected randomly. However, the odds of the former sets being selected non-randomly are greater.
JSadowski··on Pegleg: a Meteor app that crowd-sources full-length movies from YouTube
You and I see a single site where you can go and find movies people have uploaded to YouTube. The MPAA sees a single site where they can go and make their DMCA requests to YouTube. I question how long this will be useful.
JSadowski··on Facebook Home
Not at all... just less frequently
JSadowski··on Facebook Home
I like Android intents and all, but I think Facebook is misguided if their plan is to release a new version of Home every month. The intent preference is only remembered for the same version of the app... that means if they choose to update the version the user will be asked if they want to launch the intent with Facebook Home again ("Just Once" / "Always").
JSadowski··on SIP from Twilio
Unfortunately, unless I'm missing something, Twilio still appears unable to handle inbound sip
JSadowski··on New Java 0-Day Vulnerability Being Exploited in the Wild
Or permanently. I have never found a use for the Java plugin in my browser. And for all other plugins I have click-to-play enabled.
JSadowski··on I Can Detect Your Facebook Username, Using W3C Standard
No way to fix it? Not that they should, but Facebook could just stop redirecting www.facebook.com/profile.php to www.facebook.com/<username>

By making that change (and having no other way to hit a page that redirects to my user page), there is no URL for the attacker to check against.

JSadowski··on Introducing the Facebook Card, a New Type of Gift Card
That's my point... from the merchant standpoint there is no additional integration required... they just process it as a credit card. Facebook limits the spend based on the merchant identifier that gets sent to them from the POS. Basically they've created a multi-gift-card using existing credit card technology without the partners needing to update their POS to support it.
JSadowski··on Introducing the Facebook Card, a New Type of Gift Card
It looks like this is just a prepaid credit card with dedicated balances for each merchant. While I'm sure Facebook has buy-in from the merchants (as they are using their logo and other brand marks), in theory Facebook could offer gift cards for arbitrary merchants. At POS Facebook just uses the merchant identifier to determine which balance to approve funds and subtract from -- aside from that, it works like a normal prepaid credit card.
JSadowski··on NodeJS Runtime for Chrome
I for one hope that the trend actually continues: https://github.com/jonathansadowski/chrome-moneyprinter/
JSadowski··on How to run your own open source Skype replacement
I think that the most likely thing to disrupt Skype is going to be WebRTC and getUserMedia/PeerConnection.
JSadowski··on Career.fork() - How To Thrive As A Freelance Developer
Yes: an environment called life, where you have a career object and you fork it.
JSadowski··on Startup is not your job
Also, could we stop pretending that every startup founder is in it to "change the world"?
JSadowski··on Simple -- Announcing Goals
Just double-checked the date. I requested an invite in early November, 2011. So 9 months ago.
JSadowski··on Simple -- Announcing Goals
Simple looks pretty neat, but I feel like I requested an invite almost a year ago now and still haven't received one. New features are great, but meaningless to me if I can't use them.
