Ask HN: How do I choose the right resource to learn CS fundamentals?
3 by 8589934591 | 0 comments on Hacker News.
I am trying to learn CS on my own. But there are so many resources available online for every course from many of the top universities. For example: For intro courses: * Computer science an interdisciplinary approach (princeton) * CS61A - UCB * Introduction to CS and programming (MIT) * Stanford * CMU Data Structures and Algorithms: * Princeton Algorithms * CS61B - UCB * Stanford Algorithms course * MIT Algorithms * CMU Apart from this you have multiple books on each topic - Data Structures/Algorithms, Discrete Mathematics, Theory of Computation, Operating systems, Networks, and so on. Apart from these you also have resources like teachyourselfcs, ossu, functionalcs.github.io/curriculum/. I am attracted by the resources/online/books posted by courses in UCB/Princeton/MIT/Stanford/CMU. At the same time I get boggled down and overwhelmed that I have soooooooooo many materials to cover. Intro courses aren't that big of a deal since I am able to recognize/solve most questions fairly easily in multiple resources. But my next step of Data structures and algorithms is overwhelming that I am unable to start somewhere. How do you recommend to choose the right resource (online/book) for each topic/course? Is it worth going through multiple university courses/books for the same topic?

, a memo written to Huawei's 190,000 employees by the company's rotating chairman Eric Xu said that Huawei's growth slowed in the second half of this year. For 2019, the company grossed $120 billion, an 18% gain from 2018's top-line number. But revenue growth in the first half of this year was 23% indicating that the U.S. supply chain ban that was instituted in May is having a negative effect.

Because of the ban, Huawei cannot license the Google Play services version of Android which means that recent models like the Mate 30 series and the foldable cannot use ...

You know how it is when you're waiting for your brand new phone to arrive. Colors look brighter, food tastes better and repeats of "The King of Queens" start sounding like Shakespeare. And then there is that magic moment when the box arrives. You rip away the packaging and find...you've been shipped the wrong phone. This is the scenario that is playing out for several Google customers who bought an unlocked Pixel 4 straight from the Google Store. After inserting the correct SIM card into the appropriate slot, the screen says, "SIM card isn’t supported. Ask Xfinity Mobile if this device can ...

2019 has been like one big battle against bezels, and hole-punch displays seem to be one of the winners. On the other side, dual-, triple-, and quadruple-camera setups grew more and more common. Perhaps Chinese company Vivo wanted to capitalize on these trends, because it’s released a new patent with four camera cutouts.

Yes, that’s right- not one, not two, not even three, but four hole-punch selfie cameras. The new patent, spotted by , actually outlines three different ways a quadruple selfie phone could work.

Dish Network was next, spending $6.2 billion for a chunk of 600MHz airwaves.

Now, , the government is looking to reduce the costs of purchasing spectrum by offering a plan that allows some carriers to share these airwaves ...
