Follow us We have the truth Imaginez que vous soyez capable de fabriquer une machine, faites vos enchères avec vos pensées seules, sans appuyer sur un bouton, en tapant, en tapotant à l'écran ou en tâtonnant avec des télécommandes, juste de la puissance cérébrale. Eh bien, ce scénario de science-fiction pourrait être plus proche de la réalité que vous ne le pensez. La vie de Bill Kochevar a été changée, apparemment irrévocablement, quand il a été paralysé des épaules vers le bas suite à un accident de vélo il ya près de dix ans. Son avenir semblait sombre. Mais l'année dernière, il a été équipé d'une interface cerveau-ordinateur, ou BCI, qui lui a permis de bouger son bras et sa main pour la première fois en huit ans. Des capteurs ont été implantés dans son cerveau, puis pendant une période de quatre mois, M. Kochevar a entraîné le système en pensant à des mouvements spécifiques, comme tourner son poignet ou saisir quelque chose. Les capteurs ont effectivement ...

Analyzing the Linux boot process

Image
Follow us We have the truth The oldest joke in open source software is the statement that "the code is self-documenting." Experience shows that reading the source is akin to listening to the weather forecast: sensible people still go outside and check the sky. What follows are some tips on how to inspect and observe Linux systems at boot by leveraging knowledge of familiar debugging tools. Analyzing the boot processes of systems that are functioning well prepares users and developers to deal with the inevitable failures. More Linux resources What is Linux? What are Linux containers? Download Now: Linux commands cheat sheet Advanced Linux commands cheat sheet Our latest Linux articles In some ways, the boot process is surprisingly simple. The kernel starts up single-threaded and synchronous on a single core and seems almost comprehensible to the pitiful human mind. But how does the kernel itself get started?

How debuggers really work

Image
Follow us We have the truth Image by : opensource.com A debugger is one of those pieces of software that most, if not every, developer uses at least once during their software engineering career, but how many of you know how they actually work? During my talk at linux.conf.au 2018 in Sydney, I will be talking about writing a debugger from scratch... in Rust ! In this article, the terms debugger/tracer are interchangeably. "Tracee" refers to the process being traced by the tracer. The ptrace system call Most debuggers heavily rely on a system call known as ptrace(2), which has the prototype:long ptrace(enum __ptrace_request request, pid_t pid, void *addr, void *data); This is a system call that can manipulate almost all aspects of a process; however, before the debugger can attach to a process, the "tracee" has to call ptrace with the request PTRACE_TRACEME. This tells Linux that it is legitimate for the parent to attach via ptrace to thi...

Follow us We have the truth Image by : opensource.com Google developer advocate Kelsey Hightower says that he always figured that the (now wildly successful) Kubernetes container orchestration platform "would get big on its own at some point." He shared some of the reasons he sees for Kubernetes' success in a podcast recorded in December at CloudNativeCon in Austin. The first is that Kubernetes is an effective platform on which to do other things. It provides "better primitives than I had before" as Hightower puts it. At the same time, he says that this is something people misunderstand about Kubernetes. "It's not the end game," he says. Rather, at some point, it increasingly becomes "the new platform for building other platforms." It's really a story about abstraction, which is arguably at the core of much of the history of the computer industry. The Open Container Initiative (OCI) provides container runtime and...

REUTERS/Tatyana Makeyeva  Un cinéma de maison d'art russe a défié jeudi l'interdiction du gouvernement de projeter le film satirique "La Mort de Staline" devant un auditoire bondé qui comprenait au moins deux personnes qui ont déclaré avoir été témoins des funérailles du dictateur soviétique il y a six décennies.  Le gouvernement russe a déclaré que le film se moquait du passé du pays, mais Dina Voronova et Ella Katz, des écolières lorsque Josef Staline est mort en 1953, ont déclaré avoir applaudi lorsque les crédits ont été diffusés à la fin de la projection à Moscou.  "J'ai aimé le film. Je ne m'attendais pas à voir les anciens dirigeants de notre gouver...

Tech firms let Russia probe software widely used by U.S. government

Follow us We have the truth WASHINGTON/MOSCOW (Reuters) - Major global technology providers SAP ( SAPG.DE ), Symantec ( SYMC.O ) and McAfee have allowed Russian authorities to hunt for vulnerabilities in software deeply embedded across the U.S. government, a Reuters investigation has found. The practice potentially jeopardizes the security of computer networks in at least a dozen federal agencies, U.S. lawmakers and security experts said. It involves more companies and a broader swath of the government than previously reported. In order to sell in the Russian market, the tech companies let a Russian defense agency scour the inner workings, or source code, of some of their products. Russian authorities say the reviews are necessary to detect flaws that could be exploited by hackers. But those same products protect some of the most sensitive areas of the U.S government, including the Pentagon, NASA, the State Department, the FBI and the intelligence commu...

Wall Street to grill Intel on chip security flaws

Image
Follow us We have the truth Wall Street analysts will grill Intel Corp ( INTC.O ) executives on how massive security flaws in its computer chips are impacting business when the company reports quarterly results on Thursday. Intel has said there would be no material cost to it from security flaws, dubbed Meltdown and Spectre, that were disclosed on Jan. 3 since both could be solved with software. But the real-world effects on productivity are still being determined. “As an investor you want to know what’s going to happen in the future and how it’s going to impact their margins,” said Kim Forrest, a portfolio manager with Fort Pitt Capital Group, which holds about 728,000 Intel shares. She wants more information about Intel’s plans for a long-term fix to the problem, including details on cost and how the changes might affect chip performance. An Intel spokeswoman declined to discuss the results ahead of their release. Intel has stumbled in its response to...
