New top story on Hacker News: Ask HN: How do I choose the right resource to learn CS fundamentals?
No comments11 by 8589934591 | 1 comments on shero.
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?

New on SI: Eagles Finally Rise Up to Win Floundering NFC East—But Do They Have a Chance in the Playoffs?
No commentsIt came down to the final week of the season, and not in an exciting way, but the NFC East finally has a champion. As Philadelphia marches into January, where do the remainder of the teams stand?
Hey, somebody finally won the NFC East!
The state of the division has turned into something of a joke around the NFL this season, with no teams willing to rise up and take a commanding lead in the division. But heading into the final week of the season, the division was the Eagles’ to lose as they faced the Giants, with the Cowboys still having an outside chance to back into the postseason.
As expected from the this division’s teams, it took until the second half for Philadelphia to turn a corner. Giants QB Daniel Jones bobbled a low snap as Eagles safety Malcolm Jenkins blitzed and punched out the wet ball as DE Fletcher Cox followed the ball and recovered it at the one-yard line. On the next play, Philadelphia RB Boston Scott easily walked into the end zone to extend the lead, 27-17. The 9-7 Eagles ultimately beat the 4-12 Giants, 34-17, claiming the division title and the No. 4 seed in the NFC.
Scott—Philadelphia’s leading receiver (84 yards) and rusher (54 yards, three touchdowns) against the Giants—represents the identity of this Eagles team, which is making the most of players who haven’t had much opportunity in the NFL. Scott, who was drafted by the Saints in the sixth round of the 2018 draft, was signed by the Eagles off the New Orleans practice squad last December, and he was activated in October when Eagles running back Corey Clement was placed on injured reserve. Scott took on a larger role in this game when rookie running back Miles Sanders was injured in the first quarter.
Injuries have been the story of this Eagles season. DeSean Jackson was lost to an abdominal injury in Week 2, Alshon Jeffery played on and off in ten games before landing on IR, Nelson Agholor has missed the last four games, Jordan Howard hasn’t played since Week 9 and Zach Ertz was ruled out of this game with a lacerated kidney.
If you followed along on Twitter during this game, you’d find hundreds of tweets from fans asking who the hell these Eagles receivers are. Head coach Doug Pederson has been forced to reinvent his offense with a rotating cast of anonymous pass catchers: tight end Josh Perkins; receivers Deontay Burnett, Greg Ward Jr. and Robert Davis; and of course, Scott.
Burnett, an undrafted player out of USC in 2018, was on the Eagles’ practice squad less than a week ago; today, with the game tied 17-17 in the third quarter, he made an impressive 41-yard catch that put the Eagles in field goal range to seize the lead.
Philadelphia will host the winner of the 49ers-Seahawks game in next week's wild-card round, and they’ll hope to have Ertz, Howard and Sanders back for that game. If the Eagles make it one more week to the divisional round,
there’s hope they could get Jackson back. Until then, QB Carson Wentz will keep finding ways to use the unknown pass-catchers he has available.The NFC East was far and away the worst division in the league this season and there will be changes to reflect the disappointing year for three of the four teams. The Washington football team fired head coach Jay Gruden after an 0-5 start, and there’s a chance that the Cowboys and Giants may also make coaching changes of their own.
Cowboys owner Jerry Jones has been mostly noncommittal about head coach Jason Garrett’s future in Dallas. In his post-game press conference after the team was eliminated from the playoffs in Week 17, Jones told reporters, “There’s no doors shut here tonight. None.”
But then Jones also told reporters, “I can see myself making a lot of changes in a lot of areas. The times call for that.”
In his nine-and-a-half seasons as Cowboys head coach, Garrett led Dallas to the playoffs just three times—the worst decade of football in franchise history when ranked based on playoff berths. Garrett has a 85-67 overall mark, three playoff appearances, three division titles and four 8-8 finishes.
Over in Washington, the team, which fired Jay Gruden back in October, is moving quickly with its coaching search. NFL Network’s Ian Rapoport reported that ex-Panthers coach Ron Rivera is set to interview with the team tomorrow. Interim head coach Bill Callahan expressed his interest in being the team’s head coach, but it’s unlikely the team will keep him on in that role.
Whatever the Washington team does with it’s coaching decision, it should keep the development of rookie quarterback Dwayne Haskins in mind. It would be smart to retain offensive coordinator Kevin O’Connell, who has worked closely with Haskins and helped him make progress this season. Haskins has only one season of starting experience in college, so stability and consistency with his coaching will be crucial for his growth into Washington’s franchise quarterback.
NBC Sports Washington reported that team president Bruce Allen will no longer have responsibilities with the team's football operations, and his future with the organization remains unsettled. Allen’s removal will likely have a ripple effect within the front office.
In Allen’s ten years as president, the team has more than 100 losses and zero playoff wins, and has fired two head coaches—Gruden and Mike Shanahan. Off the field, Allen presided over several controversial situations: The firing of former GM Scot McCloughan, the strange case of Su’a Cravens, and Pro Bowl tackle Trent Williams’s holdout following a health issue that he claims the team mishandled.
In two seasons as the Giants’ head coach, Pat Shurmur has not had it easy. He was tasked with handling the delicate transition from Eli Manning to Daniel Jones. Jones has shown potential, but the Giants offensive line has struggled, Saquon Barkley missed much of the season with injury and the defense lacks premium talent. If Shurmur, who is 9–23 in two years as the head coach, is fired, he will be the second straight head coach for the Giants to last less than three seasons.
When Barkley tied the game 17-17 with a 68-yard touchdown run, Shurmur pulled the RB in for a big hug on the sideline. It looked like the type of desperate, emotional hug from a coach who knows his job is on the line.
Giants co-owners John Mara and Steve Tisch will also have to evaluate general manager Dave Gettleman, who was hired along with Shurmur in 2018. Will New York stay the course or upheave it all?

New on SI: Freddie Kitchens Fired by the Browns After One Frustrating Season
No commentsAfter an active offseason, notably landing WR Odell Beckham Jr., Cleveland came into the 2019 season with sky-high expectations. But the team’s 6–10 season, marred by unrest on and off the field, led the team to end Kitchens’s tenure.
After being promoted from running backs coach to interim offensive coordinator to head coach over the course of a year,
Freddie Kitchens has been fired by the Browns. The team closed out their disappointing 6–10 season with a loss to the Bengals, the worst team in the NFL this season.Kitchens was hired to coach the running backs at the beginning of 2018, and was then elevated to offensive coordinator, his first-ever coordinator gig, just a few months later when the team fired former head coach Hue Jackson and offensive coordinator Todd Haley.
After those coaching changes in 2018, Cleveland finished the season 5-3, and with Kitchens calling the plays in the latter half of the season, rookie quarterback Baker Mayfield made significant progress. In Mayfield’s first six games of the season with Haley calling the plays (starting five of those six), the QB completed 58.3% of his passes for 1,471 yards, eight touchdowns and six interceptions. In the last eight games with Kitchens calling the shots, Mayfield completed 68.4% of his passes for 2,254 yards, 19 touchdowns and eight interceptions.
Despite his lack of play calling experience, Kitchens’s connection with Mayfield gave him an advantage over other coaching candidates. GM John Dorsey took a risk on hiring the inexperienced coordinator, but the strategy made sense. He hired the coach who had already proven he could get the most out of Mayfield, the No. 1 overall pick of the 2018 draft, and the team’s most important player in determining Cleveland’s future success.
But Dorsey also admitted that Kitchens was not on any of his lists of head coaching candidates that he brought with him when he took the GM job in Cleveland in December 2017. Kitchens acknowledged the criticism that he was too inexperienced to land a head-coaching gig and that he was not the popular choice among more established candidates.
“Am I ready or not? I do not know,” Kitchens said, after being named head coach. “I mean, were you ready to be a parent? I know this, they had confidence enough in me that I would figure it out and I would get the job done.”
But after a disappointing 2019 season of questionable play calling and a lack of control over his players, it looks like Kitchens wasn’t quite ready for that jump.
When Dorsey traded for Odell Beckham Jr., the expectations for Kitchens and this Browns team grew exponentially. And one of the biggest critiques of Kitchens is that he failed to maximize the most talented roster that Cleveland has seen in years, with the frustration between the star players and their coach visible throughout the season in public spats between some of the star players and the head coach.
Receiver Jarvis Landry was caught arguing with Kitchens on the sideline during a loss at Arizona. Landry explained that he was asking Kitchens to get him the ball, because he’d only caught two catches for two yards at halftime.
A few weeks ago, Fox Sports’ Jay Glazer reported that Beckham is unhappy in Cleveland and has been going up to opposing coaches and players before games saying, ‘Come get me.’ Beckham later refuted that report, but he’s also had a strangely quiet season on the field, his worst season statistically.
In Kitchens’s first outing as head coach, an embarrassing 43-13 home loss to the Titans, his team committed 20 penalties. Those penalties continued to add up as the season wore on, peaking with the infamous meleé on Thursday Night Football when Browns defensive end Myles Garrett ripped off Steelers quarterback Mason Rudolph’s helmet and then swung it as Rudolph’s head and hit him with it. The team ended the season with the third-most penalties in the league.
A few weeks after that brawl, Kitchens was photographed wearing a t-shirt that says, ‘Pittsburgh Started It.’ Sure, it’s just a t-shirt, and there are plenty of other choices Kitchens made to seal his fate. But the head coach of a team wearing that shirt in public (and allowing a picture to be taken!) embodies the complete lack of discipline that became the identity of Kitchens’s leadership. And it reflected even worse on Kitchens when compared to Steelers coach Mike Tomlin, the coach on the other side of that fight, who refused to answer press conference questions about it. The Kitchens experiment lasted only one season, and that shirt will be his legacy.
On the morning of the Browns game at Arizona team in Week 15, NFL Network’s Ian Rapoport reported that, “barring a horrific collapse or circumstance to end the season, it appears the Browns will be moving forward with Kitchens.”
But in the final three games of the season, Cleveland lost 38-24 to Arizona, 31-15 to Baltimore and 33-23 to Cincinnati. The final loss was particularly humiliating, against a one-win Bengals team, as Mayfield threw three interceptions to finish the season with 20 interceptions and 20 touchdown passes. Yep—that certainly checks the box for an end-of-season collapse.
Since owner Jimmy Haslam bought the Browns in 2012, he has hired four different full-time head coaches (not counting Gregg Williams as the interim coach last season). Four coaches in eight seasons.
Consistency would probably do the Browns some good, but Kitchens joins Rob Chudzinksi as the second one-and-done Browns coach in Haslam's tenure. One season isn’t nearly long enough for a head coach to prove himself, but the Kitchens era is over. With a quarterback on a rookie contract and expensive, talented pieces around him, the Browns don’t have any time to waste.

New on SI: Browns Fire Freddie Kitchens After Disappointing Season
No commentsThe Browns entered the 2019 season considered to be potential Super Bowl contenders, but will instead be looking for a new head coach after Freddie Kitchens' dismissal.
The Browns entered the 2019 season considered to be
among potential Super Bowl contenders. But after a 6-10 season, littered with inconsistent play and plenty of bad press, head coach Freddie Kitchens has been fired, the team announced Sunday."I would like to thank Freddie for his dedication and efforts this past season," general manager John Dorsey said in a statement. "We are disappointed in our results and feel a change is necessary. Freddie is a good man and good football coach. We wish he and his family nothing but success."
Kitchens was in his first full season as the Browns' head coach after being promoted this past offseason.
On the field this year, the Browns' offense was in the bottom third of the league and second-year QB Baker Mayfield failed to develop the way that many expected.
Kitchens and his team also found themselves in the news throughout the year, for all the wrong reasons. Under the rookie head coach's watch, DE Myles Garrett was suspended indefinitely for striking Steelers QB Mason Rudolph with Rudolph's helmet. The coach was later spotted wearing a "Pittsburgh Started It" in the weeks following the incident. Safety Tahir Whitehead was released after directing death threats at fans on Twitter following a loss, reports surfaced that Odell Beckham Jr. was dealing with a "painful sports hernia injury since training camp and Mayfield got into a spat with a local reporter, among other notable moments.
After the team's Week 16 loss to the Ravens which eliminated Cleveland from playoff contention, Kitchens insisted that the Browns were on their way to becoming consistent winners.
"We’re really close, and sometimes that gets lost in the shuffle," he said. "But we know how close we are. Our players understand how close we are. Our players understand how they could do better. Coaches understand how they could do better, and whenever we get those things flipped, it will change."
But that change will not occur under Kitchens' watch.
After falling 33-23 to the Bengals in Week 17, the Browns will now look to hire their eighth full-time coach since 2008.

New on SI: Report: Redskins Remove Bruce Allen From Head of Football Operations Role
No commentsWashington has more than 100 losses and no playoff victories since Bruce Allen was hired as GM in 2009.
Bruce Allen was hired as the Redskins' GM during the 2009 season. After 10 years, enough is apparently enough.
Allen will no longer be running the team's football operations, according to JP Finlay of
NBC Sports. ESPN's John Keim later confirmed the news. According to ESPN, however, it is possible Allen will continue as the Redskins' president and help owner Dan Snyder try to get a new stadium built. His future role is not official yet and remains "somewhat unsettled."In the 10 years since Allen was hired, Washington has more than 100 losses and no playoff victories. The team has fired two head coaches during his tenure and has started more than 10 different quarterbacks.
When Allen joined the team, he was the first person hired by owner Dan Snyder to hold the GM title, a notable milestone after a decade of various front office arrangements that usually center around Snyder and Snyder's friend, Vinny Cerrato. He has been the primary decision maker in Washington's football decisions since the firing of Mike Shanahan in 2013.
The team will now look for a new person to head up the organization's football operations.
Despite rookie quarterback Dwayne Haskins showing positive flashes at times, the 2019 season was largely one full of struggles for Washington. Jay Gruden was relieved in early October after the team's 0-5 start, its worst open to a season since 2001. And the team will again be last in the NFC East, finishing with a losing record for the third straight season.
The 3-12 Redskins finish their season on Sunday when it looks to end the Cowboys' year as well. Kickoff is set for 4:25 p.m. ET.
