Learning To Program Is Getting Harder (slashdot.org) 408

theodp writes: While Google suggests that parents and educators are to blame for why kids can't code, Allen Downey, Professor at Olin College argues that learning to program is getting harder . Downey writes: The fundamental problem is that the barrier between using a computer and programming a computer is getting higher. When I got a Commodore 64 (in 1982, I think) this barrier was non-existent. When you turned on the computer, it loaded and ran a software development environment (SDE). In order to do anything, you had to type at least one line of code, even if all it did was another program (like Archon). Since then, three changes have made it incrementally harder for users to become programmers:
1. Computer retailers stopped installing development environments by default. As a result, anyone learning to program has to start by installing an SDE -- and that's a bigger barrier than you might expect. Many users have never installed anything, don't know how to, or might not be allowed to. Installing software is easier now than it used to be, but it is still error prone and can be frustrating. If someone just wants to learn to program, they shouldn't have to learn system administration first.
2. User interfaces shifted from command-line interfaces (CLIs) to graphical user interfaces (GUIs). GUIs are generally easier to use, but they hide information from users about what's really happening. When users really don't need to know, hiding information can be a good thing. The problem is that GUIs hide a lot of information programmers need to know. So when a user decides to become a programmer, they are suddenly confronted with all the information that's been hidden from them. If someone just wants to learn to program, they shouldn't have to learn operating system concepts first.
3. Cloud computing has taken information hiding to a whole new level. People using web applications often have only a vague idea of where their data is stored and what applications they can use to access it. Many users, especially on mobile devices, don't distinguish between operating systems, applications, web browsers, and web applications. When they upload and download data, they are often confused about where is it coming from and where it is going. When they install something, they are often confused about what is being installed where. For someone who grew up with a Commodore 64, learning to program was hard enough. For someone growing up with a cloud-connected mobile device, it is much harder.

NBC Publishes 200,000 Tweets Tied To Russian Trolls 270

An anonymous reader quotes a report from NBC News: NBC News is publishing its database of more than 200,000 tweets that Twitter has tied to "malicious activity" from Russia-linked accounts during the 2016 U.S. presidential election. These accounts, working in concert as part of large networks, pushed hundreds of thousands of inflammatory tweets, from fictitious tales of Democrats practicing witchcraft to hardline posts from users masquerading as Black Lives Matter activists. Investigators have traced the accounts to a Kremlin-linked propaganda outfit founded in 2013 known as the Internet Research Association (IRA). The organization has been assessed by the U.S. Intelligence Community to be part of a Russian state-run effort to influence the outcome of the 2016 U.S. presidential race. And they're not done. At the request of NBC News, three sources familiar with Twitter's data systems cross-referenced the partial list of names released by Congress to create a partial database of tweets that could be recovered. You can download the streamlined spreadsheet (29 mb) with just usernames, tweet and timestamps, view the full data for ten influential accounts via Google Sheets, download tweets.csv (50 mb) and users.csv with full underlying data, and/or explore a graph database in Neo4j, whose software powered the Panama Papers and Paradise Papers investigations.

NBC News' partners at Neo4j have put together a "get started" guide to help you explore the database of Russian tweets. "To recreate a link to an individual tweet found in the spreadsheet, replace 'user_key' in https://twitter.com/user_key/status/tweet_id with the screenname from the 'user_key' field and 'tweet_id' with the number in the 'tweet_id' field," reports NBC News. "Following the links will lead to a suspended page on Twitter. But some copies of the tweets as they originally appeared, including images, can be found by entering the links on webcaches like the Internet Archive's Wayback Machine and archive.is."
