Re:Ask HN: Best ways to use old iPad as dashboard on Thursday June 03, 2021 @12:50PM (#27384024)
I set up an old iPad Air to show https://www.codemancer.com/ for the last two years. It's got a clock, weather, and appointments and is readable from across the room. I've also run into crashes from Safari, which I resolved by automatically refreshing the page once an hour.
I built git-browse: https://github.com/albertyw/git-browse

After getting tired of constantly searching github and phabricator, I built a small tool that would open git repositories, files, branches, and commits in the browser.

Pretty sure it was just for Halloween (a US holiday) and they've changed it back now. I guess they also changed it internationally too?
Re:Show HN: AirCSS – Distributed Asset Delivery on Monday August 03, 2015 @08:29PM (#10000899)
How is this different from a regular CDN like Akamai, Cloudflare, etc.?
I agree with your message, but that quote could be applied to any company ever. Case studies would be more useful.

Re:Ask HN: Which video hosting services scale well? on Saturday January 17, 2015 @05:20PM (#8905743)
Disclosure: I'm working on a video delivery network company called Dendrio (www.dendr.io).

You're pretty spot on about AWS. Storage is super cheap, but data transfer can be really expensive. Also, depending on your users' habits, you'll likely want a CDN to serve your files, especially if you want to serve international markets, and I can tell you that most CDNs are very expensive for video hosting. Third party hosting like Youtube and Vimeo have limits for how you can use them which are easy to go over while full-service video hosting/analytics/monetization like Brightcove and Ooyala will cost you a house.

Shameless self-promotion: you should check us out at dendr.io. We're working on a peer to peer CDN that runs on top of your existing hosting provider (whether you do it yourself, or a CDN) to decrease your costs and give you other benefits. Feel free to email me at "albert@" our domain.

Brainfuck is just a set of symbols that map to the actions a Turing machine can make. I believe that the symbols themselves were chosen to make it difficult to read and write much like Whitespace. As for Turing machines, I'm sure there are programming books about them but I'm pretty sure their point is about studying computational theory rather than practical use.
Re:Why does GitHub let me commit as other people? on Friday May 23, 2014 @08:18PM (#7792099)
I think this is a use case of signed commits. They would allow for verification of the commit's author's identity.

Fourier Transform equation is wrong. Integral from infinity to infinity? That doesn't make sense. It should be negative infinity.

Re:Circuit Scribe: Draw Circuits Instantly on Friday November 29, 2013 @11:26PM (#6822287)
From the article they published in Advanced Materials, it seems the ink actually contains silver (the element) nanoparticles in a colloid. I'm surprised that the resistance is still that high.
Re:Julia for Numerical Computation in MIT Courses on Tuesday November 26, 2013 @03:06AM (#6799813)
Making some overgeneralizations here, software written by scientists aren't going to be as good as software written by software engineers. Their usual purpose (and their training/background) is to publish papers and writing code is just a means to an end.

Re:Square talking to banks about possible 2014 IPO on Thursday November 07, 2013 @02:35PM (#6691855)
As a person who isn't in this space, why do you say that? Is it because of increasing competition or something to do with Braintree/Paypal?
Re:Inputs.io hacked – 4100 BTC stolen on Thursday November 07, 2013 @01:26AM (#6687882)
Anybody wondering how long it will take for Bitcoin to gain enough respectability for the FBI or Secret Service to get involved after hacks like this? If the same amount of money was stolen from a normal bank, it'd likely be covered by every news outlet.
isn't this a repost of another (debunked) article that was on HN a few days ago?
Re:Users complain their Dell 6430u laptops smell like cat piss on Wednesday October 30, 2013 @01:56AM (#6639785)
My guess is that Dell laptops have incorrectly vulcanized rubber. During vulcanization, sulfur compounds are added to rubber to make it more elastic. Cat urine also contains a high amount of sulfur compounds. If Dell's suppliers got the vulcanization process wrong, sulfur could be leeching out of the laptop's rubber components.
Sorry to be pedantic, but the US dollar is not backed by US government taxation. A dollar is still quite valuable outside the US because people and institutions attach a value to the US dollar, mostly because the US economy has been the largest and most open economy in the world for several decades. Taxes set by the Treasury, like all other market forces, change and are changed by the rest of the economy.

Your example is a classic example of exchange rate problems surrounding floating currencies. Since both the USD and bitcoins are free-floating (though there are powerful institutions stabilizing the USD such as the Fed and IMF), there would be an onus to convert USD into Bitcoin until the relative value of USD was high enough to offset the conversion deficit. That, or there would need to be equally powerful institutions behind Bitcoin to buy other currencies, but it would be very hard given that there is a practical limit to the total number of Bitcoins in and out of circulation.

Re:Code at 30,000 feet on Wednesday October 16, 2013 @09:23PM (#6563128)
Yep, I find coding on planes to be pretty productive too, if only for the fact that it's not like you have anything better to do. The only hard part is looking stuff up, like APIs. I find airplanes really useful for code reviews though. I often end up with less code after a flight than before.
Re:I am open sourcing my high school APCS project on Sunday July 14, 2013 @02:34AM (#6040164)
I wonder how long it'll take College Board to move to a more expressive language like Python or Ruby. The basicness of AP CS (learning loops, recursion, and simple OO) means students don't learn enough about programming for the benefits of Java to be apparent. I knew a lot of classmates who were put off of programming by APCS, not least because of the verbosity and density of Java.
Re:Datastore API (beta) on Tuesday July 09, 2013 @05:22PM (#6015612)
Not to sound self-righteous, but the HN audience (or more plausibly, some subset within) has a high influence on what the rest of the world sees and wants.

Any Dropbox employees read HN?
