Rejected from YC (Again)
- Two months later we got an email saying that a partner would like to speak to us.
- The call went well, Michael seemed to like what we're doing, as he himself had a long history working with video startups: Justin TV, which later became Twitch (sold to Amazon) as well as Socialcam (sold to Autodesk).
- A few days after the initial call we got the email from YC inviting us to Silicon Valley to meet the partners for the final stage of the YC interviews.
- We walked away feeling like we gave it our all and on the plus side, we had our first MRR and also the opportunity to run office hours with YC before the next batch.
- Obviously, this feels like a blow as just 4 months ago we have been to interviews and took their feedback onboard.
#discussWhich non-computer science degrees apply to skills needed for a career in software development?
- Practices like thinking abstractly, thinking deeply, reasoning, constructing logical arguments and synthesising knowledge from different fields have been very useful in my programming work and career.
- Like it has been said before, I believe that the most important skill in software development is logical thinking, just before the ability to learn new skills quickly.
- After having spent a full year before graduating taking Psychology/Cognitive Science classes before transitioning to Computer Science, they helped improve me as a person and a friend.
- I'm android developer student and my knowledge is pretty good, but I have to learn a lot of conversation skills to share my opinions and the university has done a good job with me in this affaire.
- I don't know about degree much .But I think a person with good documentation skills can come in handy in software development.
Node.js Under The Hood #4 - Let's Talk About V8
- It compiles JS into machine code at run time by implementing what is called a JIT (Just In Time) compiler.
- Different from other languages like C++ which uses AoT (ahead of time) compilation, which means that we first compile, generate an executable, and then you run it.
- The first step in all compiling pipelines of almost every language out there is to generate what is called an AST (Abstract Syntax Tree).
- So as we can see in the JSON we have an opening key called type, which denotes that our code is a Program, and we have its body.
Which programming language is the best for blockchain?
- In the blockchain industry Python is used in many good projects, for example, it has its own implementation of Ethereum(pyethereum), we can use it to create contracts for NEO and smartcontracts for Hyperledger as well.
New seismic phenomenon discovered, named stormquakes
- In summer 2018, Fan and his colleagues were developing a method to study what are known as very low frequency earthquakes.
- Very low frequency earthquakes, however, are tough to trace over vast distances, since the wiggles from these events don’t always look the same from one seismometer to the next, Fan says.
- Earthquakes are common out west, rumbling as the earth shifts along a spidery network of fractures in the surface, but the eastern coast largely lacks these quake-generating features.
- Most wind-borne ocean waves generate signals at a frequency higher than the 20- to 50-second cycle of a stormquake.
- Low-frequency waves, like those found in stormquakes, won’t give the most clear signal from inside the planet, notes geophysicist Jonathan Berger of Scripps Institution of Oceanography.
Puzzling artifacts found at Europe's oldest battlefield
- Since 1997, archaeologists have been excavating miles of land along the Tollense River in northern Germany and recovering the weapons and remains of hundreds of men who fought on its banks here around 1,200 B.C. The sheer scale and violence at Tollense— considered Europe’s oldest battlefield site—put to rest a stubborn 20th-century idea that Bronze Age Europe was a relatively peaceful place.
- Think again, Dietrich says: “This assemblage is no scrap hoard.” The time period, site, and likely storage in a container are different enough from the characteristics of known Bronze Age scrap hoards to disqualify their being carried for spiritual reasons, he notes.
- Dietrich says the objects were likely personal property of someone involved in the fighting, but concedes it’s unclear whether a combatant or someone else carried them onto the battle site.
Following a river of questions in eastern India
- Countless shifting islands and sand spits called chars dot the middle reaches of the Brahmaputra River.
- This one near Jogighopa, in Assam, is nearly a mile long.
- The Brahmaputra is an 1,800-mile-long question mark.
- Past flooded paddy fields shining hazily in the sun like old mirrors with their silver backing peeled off.
- The river is so huge, so powerful, so irresistible, it collects all village sounds, enfolds them, scours them away, and washes them down into the Bay of Bengal.
- The river islands can be miles long.
- The sunbaked chars are shaped like fish, clouds, teardrops, and perhaps 200 of them dot the middle reaches of the Brahmaputra downstream from Guwahati.
- You walk the river road next to the chars.
- A few miles upstream, you watch the children of the chars carry bagfuls of greasy mud to the top of a dike road.
Why cemeteries are a surprising source of life
- Green-Wood cemetery has 7,000 trees of more than 700 different species, making it a haven for biodiversity in the concrete jungle.
- In the heart of Brooklyn, New York, one of the most densely populated places on the planet, researchers have discovered a new animal species: a shimmery beetle, smaller than a grain of rice, with an exoskeleton of olive green and red.
- A type of jewel beetle new to science was discovered in Brooklyn's Green-Wood Cemetery.
- And five years before Marc DiGirolomo discovered the new beetle at Green-Wood this summer, a relic population of redback salamanders was found in a hidden glen of the graveyard.
- Since the early 2000s, tens of millions of trees from the East Coast to the Midwest have fallen to a different invasive beetle: the emerald ash borer, introduced to the U.S. from China, which has hit cemeteries like Green-Wood and Lakewood hard.
Dark matter nightmare: What if we are just using the wrong equations?
- Could we learn how big these errors in averaging can be at least just by sufficiently large/complex matter distributions in simulation?
- Sabine wrote:“That it is difficult to average non-linear equations is of course not a problem specific to cosmology.
- These scientists have a variety of techniques to derive the correct equations, but unfortunately the known methods do not easily carry over to general relativity because they do not respect the symmetries of Einstein’s theory.”There is another field of science that deals with non-linear equations, solving the time evolution of two black holes collapse depends on the non-linear terms of GR.
- Sabine,could MOND or MOND like effects like Tully Fisher and Stacy McGaugh's RAR be simply the results of GR difficulty to average non-linear equations?also, does this discussion apply to dark matter and galaxy rotation, or also dark energy or both?
- Folks:Could you please stop submitting comments about your favorite explanations for dark matter or dark energy or your personal theories of something.
Verb-Noun vs. Noun-Verb
- They told me about how they coded puzzles to look for the state of the world (nouns) instead of the player actions (verbs).
- Congrats on your posting to HackerNews.I think the point extends well to HTTP's design, since it is explicitly VERB NOUN (e.g. GET /index.html HTTP/1.1)The reason it works there is the VERB list is explicitly narrow (effectively 4, though I suppose we're up to 6+ now)Thanks for your insights.
- That is an interesting point.I think i still prefer verb/noun, as it can make the code easier to read and (hopefully?) easier to maintain.The vast majority of the time spent in code is not creating it, it is usually changing/understanding/refactoring it.For me, it's all about making the code as clear and as close to naturally read english (or your prefered language) as possible.
- Now I understand why!It looks like this:noun |> verb1 |> verb2 |> etcI haven't seen an autocomplete that works on pipes.
