“We were alerted by Apple that inappropriate content was made available to our users and both apps were taken off the App Store. Once we have protections in place we expect the apps to be back on the App Store,” he wrote.

“Apps with user-generated content or services that end up being used primarily for pornographic content, objectification of real people (e.g. “hot-or-not” voting), making physical threats, or bullying do not belong on the App Store and may be removed without notice,” the iOS guidelines add.

Speed is of the essence in Mozilla's recovery plan, and Firefox 58 does better than its predecessor in some graphics tasks by splitting work better across the multiple processor cores that computer chips have these days.

Firefox 58 can get WebAssembly software running faster so you don't have to twiddle your thumbs waiting as long after clicking a link.

Linus calls it "very much part of the whole 'this is complete garbage' issue. The whole IBRS_ALL feature to me very clearly says 'Intel is not serious about this, we'll have a ugly hack that will be so expensive that we don't want to enable it by default, because that would look bad in benchmarks'."

"The whole point of having cpuid and flags from the microarchitecture is that we can use those to make decisions. But since we already know that the IBRS overhead is huge on existing hardware, all those hardware capability bits are just complete and utter garbage. Nobody sane will use them, since the cost is too damn high."

According to a description of the feature, Tab Warming will watch the user's mouse cursor and start "painting" content inside a tab whenever the user hovers his mouse over one.

Firefox will do this on the assumption the user wants to click and switch to view that tab and will want to keep a pre-rendered tab on hand if this occurs.

"For many cases, I don’t actually think tab warming will be very noticeable," Conley said. "In my experience, we’re able to render and upload the layers for most sites quickly enough for the difference to be negligible."

As the expert said, the gain is measured in milliseconds, but in some cases this will prevent users from viewing a blank or incompletely rendered page when switching tabs.

JavaScript UI frameworks and libraries work in cycles. Every six months or so, a new one pops up, claiming that it has revolutionized UI development.

There was a time when jQuery was the darling of JavaScript tags on Stack Overflow, accounting for almost 8% of new questions. This picture quickly changed as AngularJS and later React were released, cannibalizing jQuery’s mindshare amongst the community. Then starting around 2016, there is a quick shift from AngularJS to Angular, which represents the subsequent versions (Angular 2+), as developers began to migrate to the latest and greatest flavors of the popular framework from Google.

On Saturday, January 6, 2018, we incorrectly removed the user floatdrop and blocked the discovery and download of all 102 of their packages on the public npm Registry. Some of those packages were highly depended on, such as require-from-string, and removal disrupted many users’ installations.

However, during the time between discovery and restoration, other npm users published a number of new packages that used the names of deleted packages.

The newest Skype preview now supports the Signal protocol: the end-to-end encrypted protocol already used by WhatsApp, Facebook Messenger, Google Allo, and, of course, Signal. Skype Private Conversations will support text, audio calls, and file transfers, with end-to-end encryption that Microsoft, Signal, and, it's believed, law enforcement agencies cannot eavesdrop on.

The issues were reported by a large number of users on the Ubuntu forums, Ubuntu's Launchpad bug tracker, and Reddit thread. Only Ubuntu users running the Xenial 16.04 series appear to be affected.

A Canonical spokesperson was not available for comment on the issue, but two new Ubuntu 16.04 updates with Linux kernel image 4.4.0-109 were released two hours before this article's publication.

The technique was developed by Mozilla engineer Honza Bambas, who calls it "tailing". It works by delaying scripts from tracking domains when a page is actively loading and rendering.

Page load performance is improved by saving on network bandwidth and computing resources while loading a page, in a way that prioritizes site requests over tracking requests.

It was automatically added to Firefox users’ browsers this week with no explanation except the cryptic message, “MY REALITY IS JUST DIFFERENT THAN YOURS,” prompting users to worry on Reddit that they’d been hit with spyware.

It is currently unclear what user-privacy considerations Mozilla management made before deciding to auto-install the Mr. Robot plugin into Firefox.
