mdergosits··on No GPS required: our app can now locate underground trains
Some cities will put BLE beacons in tunnels that transmit the location and then you can find your location via the strongest beacon signal. This seems like a nice way to figure that out without installing hardware!
mdergosits··on "Thermonator is the first-ever flamethrower-wielding robot dog"
Seems like a great tool for back burns when fighting wildfires. I wonder how far it can get in the hour long battery life.

mdergosits··on Split keyboards and how to build them
Kinesis makes them for ~170 if you don’t want tenting or a palm rest
mdergosits··on Advanced Compilers: Self-Guided Online Course
I took the undergraduate version of this course while at Cornell. It was a wonderful course. I taught me a lot how computers work, and how to organize a large (for me at the time) software project.

One of the most painful parts of the the project was using Scala which had ridiculously long compile times which made iterating quite a pain.

My favorite memory was that for one project we had to submit a program written meant to stress test everyone's parser.

mdergosits··on Ask HN: How do you control your diet while working at a tech company?
I have a couple strategies: - If im hungry I drink a glass of water first. Most of the time I drink something that impulse to eat goes away while satisfying my wandering mind. - I like to eat apples, they are sweet enough to be a good snack but not very high in calories. - I bike to work (4mi each way) which helps if I do eat more than I want.
mdergosits··on Blue Apron becomes a penny stock, trading under $1 for the first time
I cook meals in SF most nights for way less than $20 for 2 people without trying, meat or seafood and veggies.
mdergosits··on Running Go on Low Memory Devices
The bring up isn't actually very painful at all. The devices we are running are armv7, so we can easily just cross compile with the standard go tooling. The syscall package and memory layout of go structs lets us do almost every without C and when need C, cgo is very easy to use.

Go's easy concurrency made developing this really easy, so I think that go would definitely be the choice regardless.

Author here, happy to answer any questions!

mdergosits··on The Intel Edison: Linux Maker Machine in a Matchbox
Intel edisons are not great for power constrained solutions since they either have full power or are off. Would be really nice to have the ability to scale the CPU frequency for lower power situations
mdergosits··on Metro areas suffering from brain drain or benefiting from brain concentration
>Still, food and other necessities are Upstate-cheap if you don't shop at Wegmans.

Where do you suggest shopping for food then? Wegmans is cheaper than Tops.

mdergosits··on SeaHash: Explained
I hope you mean 2^56 and 2^256 :)
mdergosits··on Algorithmic fitting of Japanese candy
IIRC the Chinese government will subsidize exports from china.
mdergosits··on Going Serverless: AWS and Compelling Science Fiction
Wouldn't loop detection be equivalent to solving the halting problem? Obviously a naive approach would be disallow recursion/ mutual recursion, but there are valid use cases for those that may not result in infinite execution
mdergosits··on New Tesla Model S Now the Quickest Production Car
There is a third row in the back. http://www.consumerreports.org/cro/news/2013/05/tesla-model-...

mdergosits··on Wasted in San Francisco
There's a CSA I just signed up called Imperfect Produce. They deliver boxes of produce that doesn't meet the aesthetic requirements for grocery stores. Sounds like a more economical version of this.
mdergosits··on 45 years since its creation. The C language still very popular
Sometimes I use something like:

#define ALLOC(n, type) (type)malloc(n sizeof(type))

which makes it harder to have those types of bugs, though not impossible.

mdergosits··on Google Metronome
doesn't seem to work on safari on OSX
mdergosits··on Why Pi Matters (2015)
this should have a (2015) on the title
mdergosits··on Ghost in the machine: screen contents across reboots in a Macbook Pro Retina
I had this issue with my Mid 2012 retina MacBook Pro 15 in. It was a recognized problem with one of the vendors for the displays. I got it replaced at the Apple Store some time ago.
mdergosits··on Show HN: Recipelab, a simple nutrition calculator / recipe analyzer
Is there a comparison to MyFitnessPal? I use that and it's able to import recipes from a link, or scan products using a barcode. How are you getting all of the data for different products? I tried looking up my two favorite brands of yogurt and they weren't there.
mdergosits··on Advanced Algebra textbooks
Somewhat unrelated, but I enjoy the logical dependence chart. It's nice to see the ordering of the topics. Rather than trying to figure that out for oneself
mdergosits··on Why I will be using RISC-V in my next chip
That's awesome! RISC-V seems like a well defined ISA that allows for lots of extensions. Seems like a perfect fit for a board like the parallella.
mdergosits··on What’s Hot, What’s Not, in Pots and Pans (2008)
I thought the same thing. There could've been more scientific tests, maybe an infrared camera to see the heat distribution rather than the burn marks on the parchment paper.
mdergosits··on Amazon Is Capturing Bigger Slice of U.S. Online Holiday Spending
There are plenty of places like that. I go to school in upstate NY and while I live in a decent sized town, there are plenty of towns inbetween there and NYC that are pretty barebones.
mdergosits··on Google Launchpad Accelerator: Equity-Free Accelerator Program for Startups
i'm glad to see that this isn't a silicon valley only thing or even a US only thing.
mdergosits··on Trying to speed up binary search
With a conditional move the processor executes both sides of the branch, but only "commits" the side that actually should be taken. Mis-predicting a branch on a modern OOO superscalar processor can be much more expensive than executing both sides.
mdergosits··on State of U.S. Salaries Report [pdf]
It would be interesting to see the breakdown on average salary vs experience. As someone just starting my career it would be interesting to see how it compares to having 5 or 10 years experience.

edit: the UK report has that breakdown, not sure why it was omitted from the US report.
