Ruby on Rails Creator Says AI Coding Tools Still Can't Match Most Junior Programmers

Slashdot.org - 10 hours 1 min ago
AI still can't produce code as well as most junior programmers he's worked with, David Heinemeier Hansson, the creator of Ruby on Rails and co-founder of 37 Signals, said on a recent podcast [video link], which is why he continues to write most of his code by hand. Hansson compared AI's current coding capabilities to "a flickering light bulb" -- total darkness punctuated by moments of clarity before going pitch black again. At his company, humans wrote 95% of the code for Fizzy, 37 Signals' Kanban-inspired organization product, he said. The team experimented with AI-powered features, but those ended up on the cutting room floor. "I'm not feeling that we're falling behind at 37 Signals in terms of our ability to produce, in terms of our ability to launch things or improve the products," Hansson said. Hansson said he remains skeptical of claims that businesses can fire half their programmers and still move faster. Despite his measured skepticism, Hansson said he marvels at the scale of bets the U.S. economy is placing on AI reaching AGI. "The entire American economy right now is one big bet that that's going to happen," he said.

China Clamps Down on High-Speed Traders, Removing Servers

Slashdot.org - 10 hours 41 min ago
An anonymous reader shares a report: China is pulling the plug on a key advantage held by high-frequency traders, removing servers dedicated to those firms out of local exchanges' data centers, according to people familiar with the matter. Commodities futures exchanges in Shanghai and Guangzhou are among those that have ordered local brokers to shift servers for their clients out of data centers run by the bourses, according to the people, who said the move was led by regulators. The change doesn't only affect high-frequency firms but they are likely to feel the biggest impact. The Shanghai Futures Exchange has told brokers they need to get equipment for high-speed clients out by the end of next month, while other clients need to do so by April 30, the people said. The clampdown will hit China's army of domestic high-frequency firms but will also impact a swathe of global firms that are active in the country. Citadel Securities, Jane Street Group and Jump Trading are among the foreign firms whose access to servers is being affected, the people said, asking not to be named as the matter is private.

Hard Drive Prices Have Surged By an Average of 46% Since September

Slashdot.org - 11 hours 27 min ago
Tom's Hardware: Extensive research into the pricing of some of the best hard drives on the market for large capacity, economical storage indicates that prices are beginning to increase sharply, with some of the most popular models on the market seeing increases upwards of 60%. According to research from ComputerBase, pricing analysis on 12 of the most popular mainstream drives on the market indicates an average price increase of 46% over the last 4 months. While the research and price checks on these drives track movement based on European prices (ComputerBase is a German outlet), Tom's Hardware checks on similar or identical SKUs in the U.S. indicate that the trends are indeed replicated, or perhaps worse, on the other side of the pond. CB reports that various drives like Seagate's IronWolf NAS line, Toshiba's Cloud Scale Capacity Drives, Western Digital's WD Red, and Seagate's BarraCuda lines are all showing price increases of between 23% and 66%. As noted, the average price increases clock in at 46% since September 2025.

Code.org: Use AI In an Interview Without Our OK and You're Dead To Us

Slashdot.org - 12 hours 7 min ago
theodp writes: Code.org, the nonprofit backed by AI giants Microsoft, Google and Amazon and whose Hour of AI and free AI curriculum aim to make world's K-12 schoolchildren AI literate, points job seekers to its AI Use Policy in Hiring, which promises dire consequences for those who use AI during interviews or take home assignments without its OK. Explaining "What's Not Okay," Code.org writes: "While we support thoughtful use of AI, certain uses undermine fairness and honesty in the hiring process. We ask that candidates do not [...] use AI during interviews and take-home assignments without explicit consent from the interview team. Such use goes against our values of integrity and transparency and will result in disqualification from the hiring process." Interestingly, Code.org CEO Partovi last year faced some blowback from educators over his LinkedIn post that painted schools that police AI use by students as dinosaurs. Partovi wrote, "Schools of the past define AI use as 'cheating.' Schools of the future define AI skills as the new literacy. Every desk-job employer is looking to hire workers who are adept at AI. Employers want the students who are best at this new form of 'cheating.'"

Amazon Is Buying America's First New Copper Output In More Than a Decade

Slashdot.org - 13 hours 7 min ago
An anonymous reader quotes a report from the Wall Street Journal: Amazon is turning to an Arizona mine that last year became the first new source of U.S. copper in more than a decade, to meet its data centers' ravenous appetite for the industrial metal. The mine was restarted as a proving ground for Rio Tinto's new method of unlocking low-grade copper deposits. Rio signed a two-year supply pact with Amazon Web Services, a vote of confidence for its Nuton venture, which uses bacteria and acid to extract copper from ore that was previously uneconomical to process. The move by Amazon is the latest example of a technology company rushing to secure the power and critical materials necessary to build and operate artificial-intelligence data centers. The Nuton copper will satisfy only a sliver of Amazon's needs. The biggest data centers each require tens of thousands of metric tons of copper for all the wires, busbars, circuit boards, transformers and other electrical components housed there. The 14,000 metric tons of copper cathode that Rio expects the Arizona Nuton project to yield over four years wouldn't be enough for one of those facilities. Rio deployed its bioleaching process in the recent restart of a mine east of Tucson and has partnerships to take the technology to several others in the Americas. The idea is to uncork the low-grade ore left behind at old mines and is key to Rio's plans to boost output when new discoveries are harder than ever to bring online and copper demand is surging. [...] "We work at the commodity level to find lower carbon solutions to drive our business growth," said Chris Roe, Amazon's director of worldwide carbon. "That means steel, and that means concrete, and it absolutely means copper with regard to our data centers." Roe said the copper will be routed to companies that produce components for Amazon's data centers. As part of the deal, Amazon is supplying Rio with cloud-computing and data analytics to optimize Nuton's recovery rates and help the miner expand production.

How to install KSH on FreeBSD

nixCraft - 14 hours 31 min ago
Installing KSH (KornShell) on FreeBSD can be done with either FreeBSD ports or the pkg command. The ports collection will download the KSH source code, compile it, and install it on the system. The pkg method is easier, and it will download a pre-compiled binary package. Hence, it is recommended for all users. KornShell (KSH) has a long history, and many older Unix systems and scripts rely on it. As a result, KSH remains relevant for maintaining and supporting legacy infrastructure. Large enterprises, especially those with established Unix-based systems, continue to use KSH for scripting and system administration tasks. Some industries where KSH is still commonly used include finance and telecommunications. While Bash has become the dominant shell in many Linux distributions, KSH still holds a significant presence in Unix-like environments, particularly in legacy systems. Therefore, installing KSH and practicing with it is worthwhile if you plan to work in such environments.

Linux Sed Tutorial: Learn Text Editing with Syntax & Examples

nixCraft - 14 hours 31 min ago
Sed is an acronym for "stream editor." A stream refers to a source or destination for bytes. In other words, sed can read its input from standard input (stdin), apply the specified edits to the stream, and automatically output the results to standard output (stdout). Sed syntax allows an input file to be specified on the command line. However, the syntax does not directly support output file specification; this can be achieved through output redirection or editing files in place while making a backup of the original copy optionally. Sed is one of the most powerful tools on Linux and Unix-like systems. Learning it is worthwhile, so in this tutorial, we will start with the sed command syntax and examples.

Critical Rsync Vulnerability Requires Immediate Patching on Linux and Unix systems

nixCraft - 14 hours 31 min ago
Rsync is a opensource command-line tool in Linux, macOS, *BSD and Unix-like systems that synchronizes files and directories. It is a popular tool for sending or receiving files, making backups, or setting up mirrors. It minimizes data copied by transferring only the changed parts of files, making it faster and more bandwidth-efficient than traditional copying methods provided by tools like sftp or ftp-ssl. Rsync versions 3.3.0 and below has been found with SIX serious vulnerabilities. Attackers could exploit these to leak your data, corrupt your files, or even take over your system. There is a heap-based buffer overflow with a CVSS score of 9.8 that needs to be addressed on both the client and server sides of rsync package. Apart from that info leak via uninitialized stack contents defeats ASLR protection and rsync server can make client write files outside of destination directory using symbolic links.

How to control the SSH multiplexing with the control commands

nixCraft - 14 hours 31 min ago
Multiplexing will boost your SSH connectivity or speed by reusing existing TCP connections to a remote host. This is useful when you frequently connect to the same server using SSH protocol for remote login, server management, using IT automation tools over SSH or even running hourly backups. However, sometimes your SSH command (client) will not respond or get hung up on the session when using multiplexing. Typically, this happens when your public IP changes (IPv4 to IPv6 changes when using DNS names), VPN issues, or firewall cuts connections. Hence, knowing SSH client control commands can save you time and boost your productivity when such gotchas occur.
