Comment Re:What makes an OS realtime? (Score 4, Informative) 64

Did you bother looking it up?

A real-time operating system (RTOS) is an operating system (OS) intended to serve real-time application requests. It must be able to process data as it comes in, typically without buffering delays. Processing time requirements (including any OS delay) are measured in tenths of seconds or shorter. A key characteristic of an RTOS is the level of its consistency concerning the amount of time it takes to accept and complete an application's task; the variability is jitter.[1] A hard real-time operating system has less jitter than a soft real-time operating system. The chief design goal is not high throughput, but rather a guarantee of a soft or hard performance category. An RTOS that can usually or generally meet a deadline is a soft real-time OS, but if it can meet a deadline deterministically it is a hard real-time OS.[2] An RTOS has an advanced algorithm for scheduling. Scheduler flexibility enables a wider, computer-system orchestration of process priorities, but a real-time OS is more frequently dedicated to a narrow set of applications. Key factors in a real-time OS are minimal interrupt latency and minimal thread switching latency; a real-time OS is valued more for how quickly or how predictably it can respond than for the amount of work it can perform in a given period of time.[3]

Submission + - How to fix Slashdot Beta? 17

Submitted by Forbo
Forbo writes: Since the migration to Slashdot Beta was announced, it seems all meaningful discussion has been completely disrupted with calls to boycott and protest. Rather than pull an Occupy, what can be done to focus and organize the action? What is the end goal: To revert entirely to the previous site, or to address the problems with the new site?

Submission + - AltSlashdot is coming (altslashdot.org) 3

Okian Warrior writes: I've registered "AltSlashdot.org". I intend to run a site much like Slashdot used to be — better articles, less decoration and less "in your face" functionality. I'm reviewing and getting comfortable with slashcode right now. I'm looking for volunteers to help with setup and running the site. If the site becomes profitable, I intend to hire from the pool of volunteers. If you've ever wanted to participate in a site like Slashdot, here's your chance! I'm particularly in need of people who can:
  • Set up and manage a high-traffic site (servers, load-balancers, data sites, &c)
  • Edit story submissions
  • HTML, CSS, and script creation/bugfix/repair

Submission + - Why is Slashdot ignoring the advice of so many developer articles. 2

Submitted by Anonymous Coward
An anonymous reader writes: Over the years, Slashdot has recycled plenty of articles about lousy UX, lousy design, lousy graceful degradation, lousy development practices, lousy community management, even lousy JavaScript implementations creating security problems. Did Slashdot read any of those articles?

Submission + - Dice Holdings has written off Slashdot Media at the close of 2013 (prnewswire.com) 3

$7.2 million of intangible assets and $6.3 million of goodwill related to Slashdot Media

and have only started to realize some improvement on related sites. With ad revenue declining and not expected to pick up (read: everyone who uses Slashdot uses adblocking softwarwe), it appears that the Slashdot stewardship experiment by Dice Holdings has been a financial failure. Since the site has been redesigned in a user-hostile fashion with a very generic styling, this reader surmises Dice Holdings is looking to transform or transfer the brand into a generic Web 3.0 technology property. The name may be more valuable than the user community (since we drive no revenue nor particularly use Dice.com's services).

Submission + - Fuck beta 1

An anonymous reader writes: The beta is bad. It's so bad. The comments are reduced in screen width about 50%. Subject lines are deemphasized, scores are minimized, etc.

The discussions are the reason to come to Slashdot, and the beta trivializes them entirely. It looks like the comment section on a generic news site.

The comments now look like an afterthought, whereas they used to be the primary focus of the site.

Discussion has begun to create an alternate site.
